ABSTRACT

RESUMO Objetivos: Comparar a evolução do perfil nutricional de pacientes submetidos ao bypass gástrico em Y de Roux (BGYR) e ao Sleeve, em hospitais dos setores público e privado da Saúde de Pernambuco. Método: O estudo incluiu pacientes submetidos à cirurgia bariátrica nos setores público e privado de saúde de Pernambuco no período de 2008 a 2016. Foram avaliados dados antropométricos e bioquímicos (Hemoglobina, Vitamina B12, Ferro e Ferritina) no período pré-operatório e com 3, 6 e 12 meses de pós-operatório. Resultados: Não foram registradas diferenças significativas entre os pacientes internados nos dois setores da Saúde no tocante às variáveis: níveis hemoglobina, anemia por deficiência de ferro e vitamina B12 em nenhuma das avaliações e conforme o tipo de cirurgia. Entre os pacientes submetidos ao BGYR, os níveis de ferro sérico foram significativamente menores nos pacientes do setor privado da Saúde apenas na primeira avaliação. Baixos níveis de ferritina sérica foram observados na segunda avaliação, sendo os pacientes do setor privado os que apresentaram menores valores. O sucesso cirúrgico foi significativamente maior no grupo que realizou o BGYR na rede privada. Conclusões: Com um seguimento de 12 meses pós-cirurgia bariátrica, não foi observada diferença estatisticamente significante no que diz respeito às deficiências de micronutrientes entre pacientes usuários dos setores público e privado de Saúde.


ABSTRACT Purpose: To compare the nutritional status follow up of patients who underwent Roux-en-Y gastric bypass (BGYR) and Sleeve gastrectomy (SG) in hospitals of the private and public health systems, in Pernambuco. Methods: This study included patients who underwent bariatric surgery in the public and private health systems, in Pernambuco, from 2008 to 2016. Anthropometric and biochemical (hemoglobin, B12, iron and ferritin) data were evaluated in the preoperative period and at 3, 6 and 12 months after the operation. Results: There were no significant difference between patients seen at the two health systems regarding the levels of hemoglobin, iron, anemia and vitamin B12. Patients who underwent the RYGB, presented with iron deficiency which was significantly lower for those in the private system, but only at the 3 month evaluation. Low levels of ferritin were observed at the 6 month evaluation, and patients in the private health system presented with the highest ferritin deficiency. The rate of surgical success was significantly higher in those patients undergoing the RYGB at the private system. Conclusions: After a 12-month bariatric surgery follow-up, there was no statistically significant difference regarding micronutrient deficiency between patients followed up at the private and public health systems.

ABSTRACT

SUMMARY OBJECTIVE To compare the complete blood counts, namely the plateletcrit (PCT) and Platelet-To-Lymphocyte Ratio (PLR) of healthy subjects and those with morbid obesity in the young population. METHODS We included 45 patients with morbid obesity (body mass index -BMI - greater than or equal to 45 kg/m2) and 45 healthy subjects (BMI less than or equal to 25 kg/m2) in our study. Blood samples were obtained from the participants following a 12-hour fasting period. Then we evaluated the levels of hemoglobin (Hb), hematocrit (HCT), red cell distribution width (RDW), mean platelet volume (MPV), white blood cell (WBC), PLR, platelet counts, and PCT in the complete blood count. RESULTS The morbid obesity group had significantly higher platelet counts and PCT values (p<0.001), and PLR values (p=0.033). The value of WBC was also higher in the obese group (p=0.001). MPV was lower in the obesity group but not statistically significant (p=0.815). No significant difference was found between hemoglobin and hematocrit values in these groups; but RDW valuewere higher and statistically significant in the obese group (p=0.001). CONCLUSION PLR or PCT may be more useful as a marker in determining an increased thrombotic state and inflammatory response in morbid obesity.


RESUMO OBJETIVO Comparar as contagens sanguíneas completas, nomeadamente o plateletcrit (PCT) e a razão plaquetas/linfócitos (PPL) de indivíduos saudáveis com aqueles que têm obesidade mórbida na população jovem. MÉTODOS Incluímos 45 pacientes com obesidade mórbida (índice de massa corporal superior a 45 kg/m2) e 45 indivíduos saudáveis (índice de massa corporal inferior a 25 kg/m2) em nosso estudo. Foram obtidas amostras de sangue dos participantes após um período de jejum de 12 horas. Depois, avaliamos os níveis de hemoglobina, hematócrito, largura de distribuição dos glóbulos vermelhos, volume médio de plaquetas, glóbulos brancos, razão plaquetas/linfócitos, contagem de plaquetas e plateletcrit no hemograma completo. RESULTADOS O grupo de obesidade mórbida teve contagens plaquetárias e valores plateletcrit significativamente mais elevados (p<0, 001), e valores razão plaquetas/linfócitos (p=0, 033). O valor dos glóbulos brancos também foi maior no grupo obeso (p=0, 001). O volume médio dos plateletes foi inferior no grupo da obesidade, mas não estatisticamente significativo (p=0, 815). Não foi encontrada diferença significativa entre os valores de hemoglobina e hematócrito nesses grupos, mas os valores da largura de distribuição dos glóbulos vermelhos foram mais elevados no grupo obeso e estatisticamente significativos (p=0, 001). CONCLUSÃO Relação plaquetas-linfócitos e valores de plateletcrit podem ser mais úteis como marcadores na determinação de um estado trombótico aumentado e da resposta inflamatória na obesidade mórbida.

ABSTRACT

ABSTRACT BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the commonest hepatopathy worldwide. OBJECTIVE: To investigate the correlations between NAFLD histopathological features and the levels of adipokines (adiponectin, leptin, and resistin) and circulating inflammatory markers (interleukin-6 [IL-6], interleukin-8 [IL-8], tumor necrosis factor alpha [TNF-α], and C-reactive protein [CRP]). METHODS: This is an exploratory cross-sectional study, which enrolled 19 women with obesity who underwent bariatric surgery. Biochemical characteristics evaluated included the levels of adiponectin, leptin, resistin, IL-6, IL-8, TNF-α, and CRP. NAFLD was assessed through histological examination of liver biopsies carried out during the surgical procedures. RESULTS: The mean age of the study group was 37.3±8.2 years old; mean BMI was 36.2±2.5 kg/m2. Among individuals with liver fibrosis, the levels of IL-8 were significantly higher (24.4 ± 9.7 versus 12.7 ± 6.6; P=0.016726). The intensity of fibrosis presented a significant negative correlation with the levels of adiponectin (R= -0.49379; P=0.03166); i.e. the higher the levels of adiponectin, the lower the intensity of fibrosis. The intensity of steatohepatitis presented a significant negative correlation with the levels of adiponectin (R= -0.562321; P=0.01221); this means that the higher the levels of adiponectin, the lower the intensity of steatohepatitis. CONCLUSION: Adiponectin levels were inversely correlated with the severity of fibrosis and steatohepatitis, whereas IL-8 levels were higher in individuals with liver fibrosis among individuals with obesity and NAFLD undergoing bariatric surgery. The use of these markers to assess NAFLD may bring significant information within similar populations.


RESUMO CONTEXTO: A doença hepática gordurosa não-alcoólica (DHGNA) é a hepatopatia mais comum no mundo. OBJETIVO: Investigar correlações entre as apresentações histopatológicas da DHGNA e os níveis de adipocinas (adiponectina, leptina e resistina) e marcadores sistêmicos de inflamação (interleucina-6 [IL-6], interleucina-8 [IL-8], fator de necrose tumoral alfa [TNF-α] e proteína C reativa [PCR]). MÉTODOS: Estudo transversal exploratório envolvendo 18 mulheres com obesidade submetidas à cirurgia bariátrica. As características bioquímicas avaliadas incluíram os níveis de adiponectina, leptina, resistina, IL-6, IL-8, TNF-α e PCR. A DHGNA foi avaliada através de exams histológicos de biópsias hepáticas realizadas durantes as cirurgias. RESULTADOS: A idade média foi 37,3±8,2 anos; o índice de massa corporal (IMC) médio foi 36,2±2,5 kg/m2. Entre os indivíduos com fibrose hepática, os níveis de IL-8 foram significativamente mais altos (24,4±9,7 versus 12,7±6,6; P=0,016726). A intensidade da fibrose apresentou uma correlação negativa significativa com os níveis de adiponectina (R= -0,49379; P=0,03166), demonstranso que, quanto maiores os níveis de adiponectina, menor a intensidade da fibrose. A intensidade da esteato-hepatite apresentou uma correlação negativa significativa com os níveis de adiponectina (R= -0,562321; P=0,01221), demonstrando que quanto mais altos os níveis de adiponectina, menor a intensidade da esteato-hepatite. CONCLUSÃO: Os níveis de adiponectina correlacionaram-se negativamente com a severidade da fibrose e da esteato-hepatite, enquanto os níveis de IL-8 foram maiores entre os indivíduos com fibrose hepática. O uso destes marcadores pode trazer informações significativas sobre a DHGNA em populações com obesidade.

ABSTRACT

Abstract Objective: Roux-en-Y gastric bypass (RYGB) reduces body weight and the comorbidities associated with obesity. The aim of this study was to evaluate whether glucose and lipid profiles were maintained during a 5-year follow-up period after RYGB. Subjects and methods: Anthropometric and laboratory data from 323 patients who had undergone this operation were analyzed. Differences in laboratory variables between the baseline and 12, 24, 36, 48 and 60 months postoperatively (PO) were assessed using a one-way ANOVA test to compare the three groups. Delta significance using one-way ANOVA was performed to assess anthropometric variable in the postoperative period (p < 0.05). Results: 77 patients (24%) were included in Group 1 (G1), 101 (32%) in Group 2 (G2), and 141 (44%) in Group 3 (G3). The majority of patients, 71.7% in G1, 82.8% in G2, and 70% in G3, showed high triglycerides (TG) before surgery. A decrease in weight loss was observed in all groups followed by an increase in body weight in G2 and G3 at 36, 48 and 60 months. Laboratory results for G1, G2 and G3 showed no significant differences between groups at baseline and during the post-operative period. Conclusion: Our results suggest that weight regain after RYGB has no significant impact on the long-term evolution of the lipid profile and glycemia.

ABSTRACT

ABSTRACT BACKGROUND: The glucagon-like peptides 1 and 2 (GLP-1/GLP-2) are gut hormones that may directly affect the glucose homeostasis and their activity seems to be significantly affected by chronic inflammation. OBJECTIVE: To evaluate the postprandial levels of glucagon-like peptides 1 and 2 (GLP-1/GLP-2), C-reactive protein (CRP), and the postprandial glucose and insulin levels among individuals with obesity, type 2 diabetes, and healthy controls. METHODS: An exploratory cross-sectional study, which involved individuals awaiting for bariatric/metabolic surgery and healthy controls. Postprandial levels of GLP-1, GLP-2, glucose, and insulin were obtained after a standard meal tolerance test. Inflammation was assessed by means of CRP. RESULTS: There were 30 individuals enrolled in the study, divided into three groups: non-diabetic with morbid obesity (NDO; n=11 individuals), diabetic with mild obesity (T2D; n=12 individuals), and healthy controls (C; n=7 individuals). The mean CRP levels were significantly higher in the NDO group (6.6±4.7 mg/dL) than in the T2D (3.3±2.2 mg/dL) and C groups (2.5±3.2 mg/dL) (P=0.038). The GLP-1 levels following standard meal tolerance test and the area under the curve of GLP-1 did not differ among the three groups. The GLP-2 levels were significantly lower in the NDO and T2D than in the C group following standard meal tolerance test at all the times evaluated. The area under the curve of the GLP-2 was significantly lower in the NDO and T2D groups than in the C group (P=0.05 and P=0.01, respectively). CONCLUSION: GLP-2 levels were impaired in the individuals with obesity and diabetes. This mechanism seems to be enrolled in preventing the worsening of the glucose homeostasis in these individuals.


RESUMO CONTEXTO: Os peptídeos semelhantes ao glucagon 1 e 2 (GLP-1/GLP-2) são hormônios gastrointestinais que podem afetar diretamente a homeostase glicêmica; a atividade de ambos parece ser significativamente afetada pela inflamação crônica. OBJETIVO: Avaliar os níveis pós-prandiais dos peptídeos semelhantes ao glucagon 1 e 2 (GLP-1/GLP-2), proteína C reativa (PCR) e as curvas pós-prandiais de glucose e insulina entre indivíduos com obesidade, diabetes tipo 2 e controles saudáveis. MÉTODOS: Estudo piloto transversal, que envolveu indivíduos aguardando a realização de cirurgia bariátrica/metabólica e controles saudáveis. Os níveis de GLP-1, GLP-2, glucose e insulina foram obtidos após um teste de refeição padrão. A inflamação foi avaliada através dos níveis de PCR. RESULTADOS: Houve 30 indivíduos avaliados no estudo, divididos em três grupos: obesos mórbidos sem diabetes (NDO; n=11 pacientes), diabéticos com obesidade leve (T2D; n=12 pacientes) e controles (C; n=7 pacientes). Os níveis médios de PCR foram significativamente maiores no grupo NDO (6,6±4,7 mg/dL) do que nos grupos T2D (3,3±2,2 mg/dL) e C (2,5±3,2 mg/ dL) (P=0,038). Os níveis de GLP-1 após o teste de refeição padrão e a área sob a curva do GLP-1 não diferiram significativamente entre os grupos. Os níveis de GLP-2 foram significativamente mais baixos nos grupos NDO e T2D do que no grupo C em todos os tempos avaliados. A área sob a curva do GLP-2 foi significativamente menor nos grupos NDO e T2D do que no grupo C (P=0,05 and P=0,01, respectivamente). CONCLUSÃO: Os níveis de GLP-2 encontram-se alterados em indivíduos com obesidade e diabetes. Este mecanismo parece estar envolvido na prevenção da piora da homeostase glicêmica nestes indivíduos.

ABSTRACT

ABSTRACT Objective: The objective was to conduct clinical and metabolic evaluations of obese adolescents before and after laparoscopic sleeve gastrectomy (LSG) (up to 24 months). Subjects and methods: This was designed as a retrospective, descriptive series of cases study, conducted in Instituto da Criança, São Paulo, Brazil. Analysis of clinical and laboratory data from 22 obese adolescents between 14 and 19 years old submitted to LSG between 2007 and 2014. Patients had BMI > 40 kg/m2 or BMI > 35 kg/m2 with comorbidities. Anthropometric, clinical and laboratory assessments were performed: before surgery, 6, 12, 18, and 24 months after surgery. We assessed weight loss and metabolic changes up to 24 months after LSG. Results: The mean preoperative weight and BMI were 128.5 kg (SD = 23.1) and 46.5 kg/m2 (SD = 74), respectively. There was an average weight loss of 34.5 kg in the first 12 months' post LSG, corresponding to a 60% excess weight loss (EWL), as well as an average reduction in BMI of 12.3 kg/m2. However, after 24 months, the average EWL was 45%, corresponding to an average weight regain (WR) of 13.3 kg (15%) within two years. LSG improved dyslipidemia in 67.8% of patients, a significant remission of hepatic steatosis 47% and 37.7% systemic arterial hypertension; type 2 diabetes remission was complete. Conclusions: LSG proved to be a safe and effective procedure and seems to be the new hope for the obesity epidemic.

ABSTRACT

ABSTRACT BACKGROUND Bariatric surgery has become the gold standard treatment for morbid obesity, but access to surgery remains difficult and low compliance to postoperative follow-up is common. To improve outcomes, enable access and optimize follow-up, we developed a multidisciplinary preoperative approach for bariatric surgery. OBJECTIVE To determine the impact of this program in the outcomes of bariatric surgery in the Brazilian public health system. METHODS A prospective evaluation of the individuals who underwent a preoperative multidisciplinary program for bariatric surgery and comparison of their surgical outcomes with those observed in the prospectively collected historical database of the individuals who underwent surgery before the beginning of the program. RESULTS There were 176 individuals who underwent the multidisciplinary program and 226 who did not. Individuals who underwent the program had significantly lower occurrence of the following variables: hospital stay; wound dehiscence; wound infection; pulmonary complications; anastomotic leaks; pulmonary thromboembolism; sepsis; incisional hernias; eventrations; reoperations; and mortality. Both loss of follow-up and weight loss failure were also significantly lower in the program group. CONCLUSION The adoption of a comprehensive preoperative multidisciplinary approach led to significant improvements in the postoperative outcomes and also in the compliance to the postoperative follow-up. It represents a reproducible and potentially beneficial approach within the context of the Brazilian public health system.


RESUMO CONTEXTO A cirurgia bariátrica se tornou o tratamento padrão-ouro para a obesidade mórbida, porém o acesso ao tratamento cirúrgico continua difícil e a baixa adesão ao seguimento pós-operatório é comum. Para melhorar os resultados e o índice de seguimento, nossa equipe propôs uma abordagem pré-operatória multidisciplinar para a cirurgia bariátrica. OBJETIVO Determinar o impacto deste programa nos resultados da cirurgia bariátrica em um hospital público brasileiro. MÉTODOS Avaliação prospectiva dos indivíduos que passaram por um programa multidisciplinar pré-operatório para cirurgia bariátrica e comparação de seus resultados cirúrgicos com os observados no banco de dados históricos prospectivamente coletados antes do início do programa. RESULTADOS Houve 176 indivíduos que passaram pelo programa e 226 que não passaram. Os indivíduos que passaram pelo programa apresentaram frequência significativamente menor das seguintes variáveis: tempo de internação, deiscência de ferida, infecção de ferida, complicações pulmonares, fístulas anastomóticas, tromboembolismo pulmonar, hérnias incisionais, eventrações, reoperações e mortalidade. Tanto a perda de seguimento quanto a falência na perda de peso foram também significativamente menores entre aqueles que passaram pelo programa. CONCLUSÃO: A adoção de uma abordagem multidisciplinar pré-operatória integrada levou a melhoras significativas nos resultados pós-operatórios, e também na adesão ao acompanhamento pós-operatório, representando uma abordagem reprodutível e potencialmente benéfica dentro do contexto do sistema público de saúde do Brasil.

ABSTRACT

The aim of this study was to investigate the effect of Roux-en-Y gastric bypass (RYGB) on the peripheral blood microRNAs (miRNAs) of patients with type 2 diabetes mellitus (T2DM). miRNAs are small 20- to 22-nucleotide (nt) noncoding RNAs. They constitute a novel class of gene regulators that negatively regulate gene expression at the post-transcriptional level. miRNAs play an important role in several biological processes. Twelve patients with T2DM who were scheduled to undergo laparoscopic RYGB surgery were separated into two groups, using a body mass index of 30 kg/m2 as a cut-off point. Venous blood was collected before operation and 12 months after operation. A significant change was observed in the peripheral blood miRNA expression profile of both groups after RYGB surgery compared with those before operation. The expression levels of hsa-miR-29a-3p, hsa-miR-122-5p, hsa-miR-124-3p, and hsa-miR-320a were downregulated. The methylation state of the CpG sites within an approximately 400-bp genomic DNA fragment of each of the four miRNA genes, including about 200 bp upstream and 100 bp downstream of the pre-miRNA, did not vary after RYGB surgery. With remission of T2DM in both groups, RYGB could modulate the expression level of many peripheral blood miRNAs associated with lipid metabolism, insulin secretion, beta-cell function, and insulin resistance. The expression level of peripheral blood diabetes-related miRNA varied in patients with T2DM after receiving RYGB surgery, laying a strong foundation for future studies on this subject. The molecular mechanisms underlying RYGB surgery that can cause aberrant expression of miRNA remains to be determined.

ABSTRACT

ABSTRACT Background: The role of gut hormones in glucose homeostasis and weight loss achievement and maintenance after bariatric surgery appears to be a key point in the understanding of the beneficial effects observed following these procedures. Aim: To determine whether there is a correlation between the pre and postoperative levels of both GLP-1 and GLP-2 and the excess weight loss after Roux-en-Y gastric bypass (RYGB). Methods: An exploratory prospective study which enrolled 11 individuals who underwent RYGB and were followed-up for 12 months. GLP-1 and GLP-2 after standard meal tolerance test (MTT) were determined before and after surgery and then correlated with the percentage of excess loss (%EWL). Results: GLP-2 AUC presented a significant postoperative increase (945.3±449.1 vs.1787.9±602.7; p=0.0037); GLP-1 AUC presented a non-significant trend towards increase after RYGB (709.6±320.4 vs. 1026.5±714.3; p=0.3808). Mean %EWL was 66.7±12.2%. There was not any significant correlation between both the pre and postoperative GLP-1 AUCs and GLP-2 AUCs and the %EWL achieved after one year. Conclusion: There was no significant correlation between the pre and postoperative levels of the areas under the GLP-1 and GLP-2 curves with the percentage of weight loss reached after one year.


RESUMO Racional: O papel de hormônios gastrointestinais sobre a homeostase glicêmica e a obtenção e manutenção da perda de peso após a cirurgia bariátrica parece ser elemento fundamental na compreensão dos benefícios observados após estes procedimentos. Objetivo: Determinar se há correlação entre os níveis pré e pós-operatórios de GLP-1 e GLP-2 com a perda do excesso de peso após o bypass gástrico em Y-de-Roux. Métodos: Estudo prospectivo exploratório que envolveu 11 indivíduos submetidos ao bypass gástrico, acompanhados por 12 meses. Os níveis GLP-1 e GLP-2 após um teste de refeição padrão foram determinados antes e 12 meses após a operação e então foram correlacionados com o percentual de perda do excesso de peso. Resultados: Houve aumento significativo da área sob a curva do GLP-2 após a operação (945,3±449,1 vs. 1787,9±602,7; p=0,0037); a área sob a curva do GLP-1 apresentou tendência não-significativa à elevação após o procedimento (709,6±320,4 vs. 1026,5±714,3; p=0,3808). O percentual médio de perda de peso foi 66,7±12,2%. Conclusão: Não houve nenhuma correlação significativa entre os níveis pré e pós-operatórios das áreas sob as curvas de GLP-1 e GLP-2 com o percentual de perda de peso atingido após um ano.

ABSTRACT

ABSTRACT Objective: to evaluate the effectiveness of Roux-en-Y gastric bypass in improving the glycemic profile of obese patients with type 2 Diabetes Mellitus (DM2) after 18 months of follow-up. Methods: four hundred sixty-eight pacients with DM2 and BMI ≥35 were submitted to Roux-en-Y gastric bypass, from 1998 to 2010. All patients were submitted to glycemic control analysis in the 3rd, 6th, 9th, 12th and 18th postoperative months. We considered: type 2 diabetic patients, the ones with fasting glucose ≥126mg/dl and HbA1C ≥6.5 in two dosages; high risk patients for diabetes, those who presented fasting glucose ≥ 100 to 125 mg/dl and HbA1C between 5.7%-6.4%; and normal patients, those presenting glucose <100mg/dl and HbA1C <5.7%. Such diagnostic criteria were based on the official position of Sociedade Brasileira de Diabetes, published in July, 2011. Results: The remission of DM2 was seen in 410 (87.6%) out of 468 patients 18 months after the surgery, that being a meaningful difference, with p<0.001. Fourty-eight (10.3%) patients sustained criteria for the disease and ten (2.1%) continued at high risk for DM2. Conclusions: Roux-en-Y gastric bypass was effective in the promotion and maintaince of long-term glycemic control. There are evidences showing that the remission of DM2 is not only related to weight loss and that other enteroinsular axis mechanisms must be involved.


RESUMO Objetivo: avaliar a eficácia da gastroplastia com derivação em Y-de-Roux, em pacientes obesos e portadores de Diabetes Mellitus tipo 2 (DM2), na melhoria do perfil glicêmico após 18 meses de seguimento. Métodos: foram submetidos à derivação gástrica em Y-de-Roux 468 pacientes com IMC ≥35 e portadores de DM2, no período de 1998 a 2010. Todos os pacientes tiveram a análise do controle glicêmico realizadas no terceiro, sexto, nono, 12o e 18o meses de pós-operatório. Os critérios diagnósticos de diabetes foram baseados no Posicionamento Oficial da Sociedade Brasileira de Diabetes, publicado em julho de 2011. Resultados: observou-se a remissão do DM2 em 410 pacientes (87,6%) após 18 meses da cirurgia, sendo essa diferença significativa com p-valor <0,001. A doença se manteve inalterada em 48 pacientes (10,3%), e dez pacientes (2,1%) permaneceram com o risco aumentado para DM2. Conclusão: a gastroplastia com derivação em Y-de-Roux foi efetiva na promoção e manutenção do controle glicêmico em longo prazo.

Background: Obesity and type 2 diabetes mellitus are associated to inflammatory state, which can be set off by the adipose tissue, once it is a metabolically active organ that can cause a chronic mild inflammatory state.Aim: To evaluate the correlation between preoperative C-reactive protein and postoperative complications risk in obese patients (grades II and III) after Roux-en-Y gastric bypass, with and without type 2 diabetes mellitus.Methods:Between 2008 and 2013 were analysed 209 patients (107 with diabetes), presenting body mass index >40 kg/m2or >35 kg/m2with comorbidities. During the postoperative period, two groups were evaluated: with and without complications. Preoperative ultra-sensitive C-reactive protein was measured by immunonephelometry method. Results: Complications occurred in seven patients (pulmonary thromboembolism, fistula, two cases of suture leak, pancreatitis, evisceration and upper digestive hemorrhage). No statistical significance was found regarding lipid profile and C-reactive protein between patients with and without type 2 diabetes mellitus. When compared to each other, both groups (with and without complications) presented with statistical significance regarding C-reactive protein level (7,2 mg/dl vs 3,7 mg/dl, p=0,016) and had similar weight loss percentage after 3, 6 and 12 months follow-up.Conclusions: Preoperative C-reactive protein serum level was higher in the group which presented complications after Roux-en-Y gastric bypass when compared to the group without postoperative complications.


Racional: Obesidade e diabete melito tipo 2 são associadas a estado inflamatório desencadeado pelo tecido adiposo, uma vez que é órgão metabolicamente ativo e que pode gerar estado de inflamação crônica leve.Objetivo: Avaliar a correlação entre os níveis de proteína C reativa pré-operatória e o risco de complicações pós-operatórias em obesos graus II e III após bypass gástrico em Y-de-Roux, em um grupo com e outro sem diabete melito tipo 2.Métodos: Entre 2008 e 2013 foram analisados 209 pacientes (107 diabéticos) com índice de massa corpórea acima de 40 kg/m2 ou maior que 35 kg/m2com comorbidades. No pós-operatório foi avaliado um grupo com e outro sem complicações. A proteína C reativa ultrassensível pré-operatória foi mensurada pela técnica de imunonefelometria.Resultados: Complicações ocorreram em sete pacientes (tromboembolismo pulmonar, fístula, dois casos de vazamento de sutura, pancreatite, evisceração e hemorragia digestiva alta). Não houve diferença estatística significativa em relação ao perfil lipídico e níveis séricos de proteína C reativa entre os grupos com e sem diabete. Quando comparados, os dois grupos (com e sem complicações) apresentaram significância estatística entre os níveis de proteína C reativa (7,2 mg/dl vs 3,7 mg/dl, p=0,016), sendo semelhantes em relação à percentagem de perda de peso após seguimento de 3, 6 e 12 meses.Conclusões: O nível sérico de proteína C reativa pré-operatória foi mais elevado no grupo com complicações após bypass gástrico em Y-de-Roux do que no grupo sem complicações.

ABSTRACT

Background:DiaRem score consists in preoperative model for predicting remission of type 2 diabetes mellitus in obese patients who underwent gastric bypass.Aim:To evaluate the applicability of DiaRem comparing the scores obtained preoperatively with remission of T2DM after surgery.Method:Preoperative parameters such as age, use of insulin, oral hypoglycemic agents and glycated hemoglobin, were retrospectively evaluated in diabetic patients undergoing gastric bypass during the period between July 2012 to July 2013. Through these data the DiaRem score were applied. The results of fasting blood glucose and glycated hemoglobin were requested prospectively.Results:Were selected 70 patients; the remission of T2DM after surgery was found in 42 (60%) and no remission in 28 (40%). Checking the final score, it was observed that: from 0 to 2 points, 94.1% of patients remitted completely; between 3 and 7 had remission in 68.9%, of which 42.8% complete; from 8 to 12, 57.1% achieved complete remission; between 13 to 17, 87.5% did not achieve remission and was not seen this complete remission group; between 18 to 22, 88.9% were not remitted.Conclusion:The DiaRem score showed appropriate tool to assess remission of T2DM in obese patients who will undergo gastric bypass.


Racional: Escore DiaRem consiste em modelo pré-operatório de predição de remissão de diabete melito tipo 2 (DM2) em pacientes obesos que serão submetidos exclusivamente ao bypass gástrico.Objetivo: Avaliar a aplicabilidade desse escore comparando a pontuação obtida pré-operatoriamente com a remissão de DM2 após realização da operação.Método: Foram avaliados retrospectivamente, dados clínicos e laboratoriais pré-operatórios necessários para aplicar o escore (idade, uso de insulinoterapia, uso de hipoglicemiantes orais e hemoglobina glicada) de pacientes diabéticos submetidos à gastroplastia laparotômica do tipo bypass, e após um a dois anos de acompanhamento pós-operatório, verificou-se a remissão ou não do DM2.Resultados:Selecionou-se 70 pacientes; a remissão completa foi encontrada em 35 (50%), parcial em sete (10%) e não houve remissão em 28 (40%). Verificando a pontuação final, foi visto que as expectativas lançadas pelo escore DiaRem foram atingidas, pois o grupo de pacientes que alcançou a remissão foi o mesmo que obteve as menores pontuações.Conclusão: O escore DiaRem mostrou-se ferramenta apropriada para avaliar remissão de DM2 em obesos que serão submetidos ao bypass gástrico.

ABSTRACT

Although there is no indication for surgery taking only into account the glycemic condition, results have shown that benefits can be obtained in glycemic control with bariatric surgery.Aim: To compare the glycemic behavior among type 2 diabetic and non-diabetic patients within 48 h after bariatric surgery, and clarify whether there is a reduction in blood glucose level in obese patients with diabetes before the loss of weight excess.Methods: Descriptive epidemiological study with prospective cohort design with 31 obese patients undergoing Roux-en-Y gastric bypass and sleeve gastrectomy. The patients were controlled with hemoglucotests in different periods of time: preoperative, postoperative and each 6 h after surgery for 48 h.Results: Average ambulatory blood glucose in diabetics was 120.7±2.9 mg/dl vs 91.8±13.9 mg/dl in the nondiabetic. After 48 h there was decrease in diabetics to 100.0±17.0 mg/dl (p=0.003), while the non-diabetic group did not change significantly (102.7±25.4 mg/dl; p=0.097). There were no differences between the surgical techniques. There were no death.Conclusions: Diabetic patients significantly reduced blood glucose after surgery regardless of the use of exogenous insulin or oral hypoglycemic agents.


Racional: Apesar de não haver indicação cirúrgica levando-se exclusivamente em consideração apenas o estado glicêmico, resultados já revelaram que pode ser obtido benefício no controle da glicemia com operação bariátrica.Objetivos: Comparar o comportamento glicêmico dos pacientes diabéticos tipo 2 ou não nas 48 h após cirurgia bariátrica, e esclarecer se há redução nos níveis glicêmicos de obesos com diabete antes da perda de excesso de peso.Métodos: Realizou-se estudo epidemiológico descritivo com delineamento de coorte prospectiva de 31 pacientes obesos submetidos ao bypass gástrico em Y-de-Roux e gastrectomia vertical. Acompanhou-se o hemoglicoteste nos momentos pré, trans, pós-operatório e a cada 6 h após a operação durante 48 h.Resultados: A glicemia ambulatorial média nos diabéticos era 120,7±2,9 mg/dl vs 91,8±13,9 mg/dl nos não diabéticos. Após 48 h houve queda nos diabéticos para 100,0±17,0 mg/dl (p=0,003), enquanto o grupo não diabético não se modificou de forma significante (102,7±25,4 mg/dl; p=0,097). Não houve diferenças quanto às técnicas cirúrgicas empregadas. Não houve óbito.Conclusões: Os pacientes diabéticos reduziram significativamente a glicemia após a operação independentemente do uso de insulina exógena ou drogas hipoglicemiantes orais.

ABSTRACT

Context Severe obesity affects the body favoring the development of serious diseases, including hypertension, diabetes mellitus, atherosclerosis and non alcoholic fatty liver disease. Bariatric procedures increased in Brazil in the last decade. Objectives The purpose of this study was to verify if gender and age in date of procedure resulted significant differences in metabolic syndrome parameters after surgery. Methods The study involved 205 medical records of adult patients undergoing Roux-en-Y gastric bypass, stratified by gender and age groups and followed one year by a multidisciplinary team. Results It was observed significant decrease in body mass index, fasting glucose and insulin at all ages and both genders. Lipid profile showed significant improvements except high density lipoprotein cholesterol. Ectopic fat in the liver has decreased after 6 months in patients classified with steatosis at baseline. Patients classified as hypertensive blood pressure levels decreased 6 months after surgical intervention. Conclusions Roux-en-Y gastric bypass proved to be an important tool in remission of metabolic syndrome parameters. The reduction of body mass accompanied to decrease in insulin resistance resulted in lower prevalence of comorbidities associated with obesity. The benefits were similar and extended both genders and all age groups between 18 and 65 years old. .


Contexto A obesidade severa favorece o desenvolvimento de doenças graves, como hipertensão, diabetes mellitus, aterosclerose e esteatose hepática. Na última década, houve um aumento de procedimentos bariátricos no Brasil. Objetivos O objetivo deste estudo foi verificar se o gênero e a idade no momento da cirurgia implicam em diferenças significativas nos parâmetros da síndrome metabólica. Métodos Estudo envolveu 205 prontuários de pacientes adultos submetidos à derivação gástrica em Y-de-Roux, estratificada por gênero e faixas etárias, acompanhados por equipe multidisciplinar com seguimento de 1 ano. Resultados Observou-se diminuição significativa do índice de massa corporal, glicemia e insulina em todas as idades e ambos os gêneros. O perfil lipídico apresentou melhorias significativas, exceto na fração da lipoproteína de alta densidade. Os níveis de gordura ectópica no fígado diminuíram depois de 6 meses. Houve uma diminuição na prevalência de hipertensos 6 meses após a intervenção cirúrgica. Conclusões A derivação gástrica em Y-de-Roux mostrou melhora dos parâmetros da síndrome metabólica. A redução da massa corporal acompanhada da diminuição na resistência à insulina resultou em menor prevalência de comorbidades associadas à obesidade. Os benefícios foram similares e estenderam-se para ambos os gêneros e todas as faixas etárias entre 18 e 65 anos de idade. .

ABSTRACT

OBJECTIVES: To evaluate the prevalence of goiter and nodular disease in patients with class III obesity, and to correlate results with serum leptin levels and insulin resistance (IR) parameters. SUBJECTS AND METHODS: A cross-sectional study was performed to assess thyroid ultrasound (US) patterns, HOMA-IR, serum leptin, and TSH levels in obese patients and controls. RESULTS: Thyroid volume was positively correlated with body mass index (BMI) (r = 0.240, p = 0.039) and with HOMA-IR (r = 0.329; p < 0.01). Thyroid US patterns were similar between groups. However, when data from the male group was considered, greater thyroid volume was detected in the obese group compared with controls (10.8 vs. 8.5 cm³; p = 0.04). Also, nodules were more frequently detected (67% vs. 18%), as were nodules requiring FNAB (33.3% vs. 0%, p ≥ 0.05-0.09), in this group. CONCLUSION: Although IR did not correlate directly with the presence of nodules, the results support the hypothesis of a direct association between insulin resistance and thyroid volume.


OBJETIVOS: Avaliar a prevalência de bócio e doença nodular tireoidiana em pacientes com obesidade grau III e correlacionar os resultados com os níveis de leptina e parâmetros de resistência à ação da insulina (RI). SUJEITOS E MÉTODOS: Estudo seccional foi desenvolvido realizando ultrassonografia (US) tireoidiana e níveis séricos de HOMA-IR e TSH nos pacien­tes obesos e nos controles. RESULTADOS: Volume tireoidiano foi positivamente correlacionado com índice de massa corporal (IMC) (r = 0,240, p = 0,039) e com HOMA (r = 0,329; p < 0,01). Volume tireoidiano e prevalência de doença nodular tireoidiana foram similares entre os grupos. Quando avaliado o subgrupo masculino, maiores volumes tireoidianos foram detectados no grupo dos obesos comparados aos controles (10,8 vs. 8,5 cm³; p = 0,04), nódulos foram mais frequentes (67% vs. 18%), assim como nódulos com indicação de punção (33,3% vs. 0%, p ≥ 0,05-0,09). CONCLUSÃO: Embora RI não se correlacione diretamente com a presença de nódulos, os resultados suportam a hipótese da direta associação entre resistência à ação da insulina e volume tireoidiano.

ABSTRACT

RACIONAL: A vitamina A participa de várias funções primordiais no organismo humano e as suas concentrações séricas podem estar diminuídas nas doenças crônicas não transmissíveis. OBJETIVO: Avaliar a relação entre o estado nutricional da vitamina A, e a regressão da esteatose hepática em indivíduos submetidos à gastroplastia em Y-de-Roux para tratamento da obesidade classe III. MÉTODOS: Foram estudados 30 pacientes obesos classe III, de ambos os sexos, com esteatose hepática, submetidos à gastroplastia em Y-de-Roux. Seis meses após a operação, os pacientes foram submetidos à ultrassonografia abdominal e distribuídos em dois grupos: grupo 1 - pacientes com esteatose detectada na ultrassonografia e grupo 2 - pacientes sem esteatose detectada na ultrassonografia. No pré-operatório e seis meses após a operação foram realizadas análises antropométricas e exames bioquímicos: insulina basal, glicemia, Homeostasis Model Assessment Index (HOMA IR), colesterol, HDL, LDL, triglicerídeos, AST, ALT, Gama-GT, albumina, bilirrubina total, retinol, e beta caroteno. RESULTADOS: A média de perda de peso foi de 35,05 + 10,47 (p<0,01) e a diminuição no Índice de Massa Corporal (IMC) de 11,6 + 4,99 Kg/m² (p<0,01). Após seis meses, todos os exames bioquímicos apresentaram diminuição significativa das concentrações (p<0,05). O grupo 2 (sem esteatose) apresentou no pós-operatório, concentrações significativamente inferiores (p<0,05), nas variáveis: peso, IMC, AST, ALT, gama GT, HOMA IR, insulina basal. As concentrações séricas de albumina apresentaram valores médios aproximados, sem diferença significativa nos dois tempos avaliados. Observaram-se concentrações séricas mais elevadas de retinol e de β-caroteno e redução menor em relação as concentrações do pré-operatório nos pacientes sem esteatose, porém sem diferença estatística. CONCLUSÃO: Adequado estado nutricional de vitamina A pode contribuir na regressão da esteatose hepática em pacientes submetidos à Gastroplastia em Y-de-Roux para tratamento da obesidade classe III.


BACKGROUND: Vitamin A participates in several essentials functions in the human body and their serum concentrations may be decreased in non-transmissible diseases. AIM: To assess the relationship of the nutritional status of Vitamin A through the serum concentrations of retinol and beta carotene, with regression of hepatic steatosis in individuals who undergone Roux-en-Y gastric bypass surgery for treatment of class III obesity. METHODS: Were included 30 individuals, male and female, submitted to Roux-en-Y gastric bypass for treatment of class III obesity, who were diagnosed through an abdominal ultrasonography as presenting hepatic steatosis. From the result of an ultrasonography screened six months after the surgical procedure those subjects were divided into two groups: group 1 - patients with steatosis detected in the ultrasonography (16 subjects) and group 2 - patients without steatosis detected in the ultrasonography (14 subjects). Before and six months after the surgery, were carried out anthropometrical analyses and biochemical exams (basal insulin, glicemy, Homeostasis Model Assessment Index (HOMA IR), cholesterol, HDL, LDL, triglycerides, AST, ALT, Gamma-GT, albumin, total bilirubin, retinol, and beta carotene. RESULTS: The individuals presented an average weight loss of 35.05 + 10.47 (p<0.01) and a decrease in the Body Mass Index (BMI) of 11.6 + 4.99 Kg/m² (p<0.01). After six months, all the biochemical exams presented a significant decrease in their basal concentrations (p<0.05). In the post-operative period the group 2 (without steatosis) presented concentrations significantly lower (p<0.05) in the following variables: weight, BMI, AST, ALT, Gamma-GT, HOMA IR, basal insulin. The albumin serum concentrations presented close average values, with no significant difference in the two periods evaluated. In the assessment of retinol and beta carotene, higher serum concentrations and a small decrease in relation to the concentrations of the pre-operative period in the group without steatosis were observed, however, no statistical difference was found. CONCLUSION: An adequate nutritional status of vitamin A might contribute in the improvement of the hepatic esteatosis after Roux-en-Y gastric bypass for class III obesity treatment.

ABSTRACT

Background: Several studies have analyzed the relation between obesity and the hormonal imbalances generated by overweight and a family history of breast cancer. All of these factors are potentially implicated in the early development of breast cancer. Aim: To verify the existence of a significant relation between the nutritional status of breast cancer patients, their hormone serum levels (estrogens, prolactin, and progesterone), and the existence of a family history of breast cancer. Material and Methods: Retrospective data was collected from clinical records of524 women diagnosed with breast cancer in a Spanish hospital. Results: There was a positive association between estrogen, progesterone and prolactin serum levels and body mass index. The elevations in hormone levels occurred earlier in life among women with a family history of breast cancer. A two way ANOVA found a significant association between progesterone and prolactin levels with the age at diagnosis of breast cancer. Conclusions: Extreme serum levels of these hormones appear to be related to the early development of breast cancer, which in turn is influenced by the existence of a family history of cancer among those women with normal or average hormone levels.

ABSTRACT

OBJETIVO: Investigar a associação entre doença hepática gordurosa não alcoólica (DHGNA) e os marcadores de lesão e função hepática com os componentes da síndrome metabólica (SM) em indivíduos obesos classe III. MÉTODOS: A população estudada foi constituída por 144 pacientes com obesidade classe III (IMC > a 40 kg/m²). A SM foi identificada segundo o critério do NCEP ATP III, por meio da determinação do perfil lipídico, glicemia e insulina basal. Foram quantificados ainda os marcadores de função e lesão hepática. A resistência à insulina (RI) foi verificada pelo índice HOMA-IR e o diagnóstico da DHGNA por ressonância magnética. Os cálculos estatísticos foram realizados pelo programa estatístico SPSS na versão 13.0. A associação foi verificada pelo teste Mann-Whitney e qui-quadrado, com nível de significância de 5%. RESULTADOS: Foi encontrada associação significativa entre o diagnóstico de SM e DHGNA (χ² = 6,84; p = 0,01). Quanto aos componentes diagnósticos para SM, constatou-se associação positiva e significativa entre HDL-c (p = 0,05), circunferência da cintura (p < 0,05) e hipertensão arterial (χ² = 4,195; p = 0,041) com a DHGNA. O índice HOMA-IR (p < 0,001) também apresentou associação positiva com a doença hepática. CONCLUSÃO: Constatouse associação positiva e significativa entre DHGNA e componentes da SM em indivíduos obesos classe III, sugerindo a necessidade e importância do monitoramento desses componentes para rastreamento da DHGNA.


OBJECTIVE: To investigate the association between non-alcoholic fatty liver disease (NAFLD) and liver function/injury markers with components of metabolic syndrome (MS) in class III obese individuals. METHODS: The study population consisted of 144 patients with class III obesity (body mass index [BMI] > 40 kg/m²). MS was diagnosed according to the National Cholesterol Education Program - Adult Treatment Panel III (NCEP ATP III) criteria, by determining the lipid profile, blood glucose and basal insulin. Liver function/injury markers were also quantified. Insulin resistance (IR) was measured by HOMA-IR and NAFLD diagnosis was established by magnetic resonance imaging (MRI). Statistical calculations were performed by SPSS version 13.0. The association was assessed by the Mann-Whitney and Chi-square tests, with a level of significance set at 5%. RESULTS: There was a significant association between the diagnosis of MS and NAFLD (χ² = 6.84, p = 0.01). As for the diagnostic components of MS, there was a positive and significant association between HDL-C (p = 0.05), waist circumference (p < 0.05) and hypertension (χ² = 4.195, p = 0.041) with NAFLD. HOMA-IR (p < 0.001) also showed a positive association with liver disease. CONCLUSION: A positive and significant association between NAFLD and components of metabolic syndrome in class III obese individuals was observed, suggesting the need and importance of monitoring these components for NAFLD screening.

ABSTRACT

OBJECTIVE: The purpose of the study was to investigate the prevalence of hyperuricemia in morbidly obese subjects before and after Roux-en-Y gastric bypass (RYGBP) and its relationship with metabolic syndrome abnormalities. SUBJECTS AND METHOD: We evaluated 420 morbidly obese patients. Pre and postoperative (8 months after RYGBP) blood samples were drawn. Obese patients underwent laparoscopic RYGBP and after eight months all the tests were repeated. RESULTS: The overall prevalence of hyperuricemia was 34.28 percent. Hyperuricemia was more common in men than in women (51.72 vs. 29.72 percent; p = 0.0002). Men with hyperuricemia were more likely to have diabetes (p = 0.034) and more elevated fasting plasma glucose levels (p = 0.027). Women with hyperuricemia were more likely to have hypertension (p = 0.003), metabolic syndrome (p = 0.001), elevated triglycerides (p = 0.001) and GGT (p = 0.009), and decreased HDL (p = 0.011). After surgery, uric acid levels decreased from 5.60 ± 1.28 to 4.23 ± 1.20 (p < 0.0001). The prevalence of hyperuricemia decreased from 33.6 percent to 6.4 percent (p < 0.0001), in men from 48.3 percent to 17.2 percent (p < 0.0001) and in women from 29.7 percent to 3.6 percent (p < 0.0001). CONCLUSION: Concentrations of uric acid were associated with the prevalence of metabolic abnormalities in this sample of morbidly obese patients. Also, weight loss after RYGBP can reduce uric acid levels and the prevalence of hyperuricemia.


OBJETIVO: O objetivo do estudo foi investigar a prevalência de hiperuricemia em pacientes obesos mórbidos antes e após o bypass gástrico com reconstrução em Y-de-Roux (RYGBP) e sua relação com anormalidades da síndrome metabólica. SUJEITOS E MÉTODOS: Foram avaliados 420 pacientes com obesidade mórbida. Amostras de sangue pré e pós-operatório (8 meses após RYGBP) foram obtidas. Os pacientes obesos foram submetidos a RYGBP laparoscópica e após oito meses todos os testes foram repetidos. RESULTADOS: A prevalência de hiperuricemia foi 34,28 por cento. A hiperuricemia foi mais comum em homens do que em mulheres (51,72 vs. 29,72 por cento, p = 0,0002). Homens com hiperuricemia foram mais propensos a ter diabetes (p = 0,034) e tinham níveis mais elevados de glicemia de jejum (p = 0,027). Mulheres com hiperuricemia foram mais propensas a ter hipertensão arterial (p = 0,003), síndrome metabólica (p = 0,001), triglicérides elevado (p = 0,001) e GGT (p = 0,009) e diminuição de HDL (p = 0,011). Após a cirurgia, os níveis de ácido úrico diminuíram de 5,60 ± 1,28 para 4,23 ± 1,20 (p < 0,0001). A prevalência de hiperuricemia diminuiu 33,6 por cento para 6,4 por cento (p < 0,0001), em homens de 48,3 por cento para 17,2 por cento (p < 0,0001) e nas mulheres de 29,7 por cento para 3,6 por cento (p < 0,0001). CONCLUSÃO: As concentrações de ácido úrico foram associadas com a prevalência de anormalidades metabólicas nesta amostra de pacientes com obesidade mórbida. Além disso, a perda de peso após RYGBP pode reduzir os níveis de ácido úrico e a prevalência de hiperuricemia.

ABSTRACT

CONTEXT: Morbidly obese patients have an increased risk for nonalcoholic fat liver disease. Its severe form, nonalcoholic steatohepatitis may cause liver fibrosis. The diagnosis of advanced fibrosis has great value during the pre operative evaluation for bariatric surgery. Currently, liver biopsy is the gold standard for diagnosis of liver fibrosis. OBJECTIVE: To evaluate the nonalcoholic fat liver disease fibrosis score in morbidly obese patients undergoing Roux-en-Y gastric bypass in our population. METHODS: One hundred fifty-eight morbidly obese patients that had undergone bariatric surgery were included. Age, body mass index, hyperglycemia, platelet count, albumin and AST/ALT ratio were applied to the score formula. Scores above 0.676 were indicative of advanced liver fibrosis and scores under -1,455 absence of advanced liver fibrosis. These scores were compared to liver biopsy findings. RESULTS: The presence of advanced fibrosis could be diagnosed with good accuracy, with a positive predictive value of 83.7 percent. The score had a higher accuracy to exclude advanced fibrosis with a negative predictive value of 97 percent. Twenty-five patients (16 percent) had scores between the cutoffs points and were identified as indeterminate. The score sensibility and specificity was 83 percent and 97 percent respectively. CONCLUSIONS: The nonalcoholic fat liver disease fibrosis score has high accuracy to identify and exclude advanced liver fibrosis in morbidly obese patients subjected to bariatric surgery.


CONTEXTO: Pacientes com obesidade mórbida apresentam risco significativo para doença hepática gordurosa não-alcoólica e para suas formas mais graves, a esteatohepatite e a cirrose hepática. O diagnóstico de tais alterações é importante, principalmente na avaliação pré-operatória de cirurgia bariátrica. Até o momento, a biopsia hepática é o procedimento com maior precisão para tal diagnóstico. OBJETIVO: Avaliar o escore de fibrose hepática em doença hepática gordurosa não-alcoólica em pacientes com obesidade mórbida na população brasileira. MÉTODOS: Foram incluídos 158 pacientes com obesidade mórbida submetidos a cirurgia bariátrica. Idade, índice de massa corporal, hiperglicemia, albumina, contagem de plaquetas e razão AST/ALT foram aplicados à fórmula do escore de fibrose. Valores acima de 0,676 indicavam fibrose avançada e abaixo de - 1,455 indicavam ausência de fibrose. Estes valores foram comparados com os achados de biopsia hepática realizados no intra-operatório. RESULTADOS: A presença de fibrose avançada foi diagnosticada com boa precisão, valor preditivo positivo de 83,7 por cento. O escore teve melhor precisão para excluir fibrose avançada, com valor preditivo negativo de 97,2 por cento. Em 25 pacientes (16 por cento) o escore resultou indeterminado entre os pontos de corte. A sensibilidade e a especificidade do escore foram de 83 por cento e 97 por cento, respectivamente. CONCLUSÃO: O escore de fibrose para doença hepática gordurosa não-alcoólica apresenta elevada precisão para reconhecer e excluir fibrose avançada em pacientes com obesidade mórbida submetidos a cirurgia bariátrica.
