Comprehensive analysis of morbidity and mortality patterns in familial partial lipodystrophy patients: insights from a population study.

Background: There is a lack of information on the clinical and molecular presentation of familial partial lipodystrophy (FPLD), a rare genetic disorder characterized by partial subcutaneous fat loss. Objective: This study aimed to provide a comprehensive assessment of the clinical, metabolic, and genetic features of FPLD in the Brazilian population. Methods: In a multicenter cross-sectional investigation we evaluated patients with FPLD across five Brazilian reference centers for lipodystrophies. Diagnosis of FPLD was made by clinical evaluation and genetic confirmation. Data on genetic, clinical, and metabolic characteristics were captured. Statistical analysis involved the utilization of the Kruskal-Wallis test to identify differences. Results: The study included 106 patients with genetic confirmation of FPLD. The mean age was 44 ± 15 years, and they were predominantly female (78.3%). LMNA pathogenic variants were identified in 85.8% of patients, PPARG in 10.4%, PLIN1 in 2.8%, and MFN2 in 0.9%. Diabetes mellitus (DM) was highly prevalent (57.5%), affecting 54 females (50.9%). Median triglycerides levels were 199 mg/dL (54-2724 mg/dL), severe hypertriglyceridemia (≥ 500 mg/dL) was found in 34.9% and pancreatitis in 8.5%. Metabolic-associated fatty liver disease (MAFLD) was observed in 56.6%, and cardiovascular disease in 10.4%. The overall mortality rate was 3.8%, due to cardiovascular events. Conclusion: This study presents an extensive cohort of Brazilian patients with FPLD, predominantly DM with several multisystem complications. A comprehensive characterization of lipodystrophy syndromes is crucial for effective patient management and care.

Gestational and neonatal outcomes of women with partial Dunnigan lipodystrophy.

Introduction: Lipodystrophies are a group of disorders characterized by selective and variable loss of adipose tissue, which can result in an increased risk of insulin resistance and its associated complications. Women with lipodystrophy often have a high frequency of polycystic ovary syndrome (PCOS) and may experience gynecological and obstetric complications. The objective of this study was to describe the gestational outcomes of patients with familial partial lipodystrophy type 2 (FPLD2) at a reference center with the aim of improving the understanding and management of pregnant women affected by this condition. Methods: This was a retrospective analysis of data obtained from questionnaires regarding past pregnancies and a review of medical records from the beginning of follow-up in outpatient clinics. Results: All women diagnosed with FPLD2 who had previously become pregnant were included in this study (n=8). The women in the study experienced pregnancies between the ages of 14 and 38 years, with an average of 1.75 children per woman. The pregnancies in question were either the result of successful conception within 12 months of attempting to conceive or unplanned pregnancies. During pregnancy, two women (25%) were diagnosed with gestational diabetes mellitus (GDM), one (12.5%) with gestational hypothyroidism, and one (12.5%) with preeclampsia. Among the 17 pregnancies, two miscarriages (11.8%) occurred, and five cases (29.4%) of macrosomia were observed. Four instances of premature birth and an equal number of neonatal hypoglycemia cases were recorded. The reported neonatal complications included an unspecified malformation, respiratory infection, and two neonatal deaths related to heart malformation and respiratory distress syndrome. Conclusion: Our data showed a high frequency of fetal complications in women with FPLD2. However, no instances of infertility or prolonged attempts to conceive have been reported, highlighting the significance of employing effective contraception strategies to plan pregnancies at optimal times for managing metabolic comorbidities.

Brazilian evidence-based guideline for screening, diagnosis, treatment, and follow-up of metabolic dysfunction-associated steatotic liver disease (MASLD) in adult individuals with overweight or obesity: A joint position statement from the Brazilian Society of Endocrinology and Metabolism (SBEM), Brazilian Society of Hepatology (SBH), and Brazilian Association for the Study of Obesity and Metabolic Syndrome (Abeso).

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as Nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in individuals with overweight or obesity. In this context, a panel of experts from three medical societies was organized to develop an evidence-based guideline on the screening, diagnosis, treatment, and follow-up of MASLD. Material and methods: A MEDLINE search was performed to identify randomized clinical trials, meta-analyses, cohort studies, observational studies, and other relevant studies on NAFLD. In the absence of studies on a certain topic or when the quality of the study was not adequate, the opinion of experts was adopted. Classes of Recommendation and Levels of Evidence were determined using prespecified criteria. Results: Based on the literature review, 48 specific recommendations were elaborated, including 11 on screening and diagnosis, 9 on follow-up,14 on nonpharmacologic treatment, and 14 on pharmacologic and surgical treatment. Conclusion: A literature search allowed the development of evidence-based guidelines on the screening, diagnosis, treatment, and follow-up of MASLD in individuals with overweight or obesity.

2023 UPDATE: Luso-Brazilian evidence-based guideline for the management of antidiabetic therapy in type 2 diabetes.

BACKGROUND: The management of antidiabetic therapy in people with type 2 diabetes (T2D) has evolved beyond glycemic control. In this context, Brazil and Portugal defined a joint panel of four leading diabetes societies to update the guideline published in 2020. METHODS: The panelists searched MEDLINE (via PubMed) for the best evidence from clinical studies on treating T2D and its cardiorenal complications. The panel searched for evidence on antidiabetic therapy in people with T2D without cardiorenal disease and in patients with T2D and atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), or diabetic kidney disease (DKD). The degree of recommendation and the level of evidence were determined using predefined criteria. RESULTS AND CONCLUSIONS: All people with T2D need to have their cardiovascular (CV) risk status stratified and HbA1c, BMI, and eGFR assessed before defining therapy. An HbA1c target of less than 7% is adequate for most adults, and a more flexible target (up to 8%) should be considered in frail older people. Non-pharmacological approaches are recommended during all phases of treatment. In treatment naïve T2D individuals without cardiorenal complications, metformin is the agent of choice when HbA1c is 7.5% or below. When HbA1c is above 7.5% to 9%, starting with dual therapy is recommended, and triple therapy may be considered. When HbA1c is above 9%, starting with dual therapyt is recommended, and triple therapy should be considered. Antidiabetic drugs with proven CV benefit (AD1) are recommended to reduce CV events if the patient is at high or very high CV risk, and antidiabetic agents with proven efficacy in weight reduction should be considered when obesity is present. If HbA1c remains above target, intensification is recommended with triple, quadruple therapy, or even insulin-based therapy. In people with T2D and established ASCVD, AD1 agents (SGLT2 inhibitors or GLP-1 RA with proven CV benefit) are initially recommended to reduce CV outcomes, and metformin or a second AD1 may be necessary to improve glycemic control if HbA1c is above the target. In T2D with HF, SGLT2 inhibitors are recommended to reduce HF hospitalizations and mortality and to improve HbA1c. In patients with DKD, SGLT2 inhibitors in combination with metformin are recommended when eGFR is above 30 mL/min/1.73 m2. SGLT2 inhibitors can be continued until end-stage kidney disease.

Impact of an educational intervention in the management of individuals with uncontrolled type 2 diabetes mellitus using insulin therapy.

OBJECTIVE: To investigate the effects of problematizing intervention in the treatment of individuals with type 2 diabetes mellitus. METHODOLOGY: A randomized clinical trial was conducted in 41 patients ages 18 to 64 with type 2 diabetes who were treated with insulin and had glycosylated hemoglobin greater than 7.0%. The mean age of participants was 55.9 (SD = 5.49). A high percentage of patients had comorbidities such as hypertension (92.7%), dyslipidemia (68.3%), overweight (95%), retinopathy (41%), and neuropathy (39%). The patients in the intervention group participated in 6 educational groups using problematization methodology, whereas the patients in the control group attended only routine consultations. Sociodemographic, clinical, behavioral, and lifestyle variables were assessed. RESULTS: After 6 months of follow-up, no statistically significant difference in glycemic control and anthropometric parameters was observed between participants in either study group. The intervention group showed an increase in knowledge about the disease, and an improvement in total cholesterol and uric acid levels. CONCLUSION: The use of a problematizing intervention provided an improvement in behavioral as well as specific clinical parameters, compared to routine diabetes care. However, longer follow-up time for these patients could bring benefits regarding glycemic control.

Portuguese-Brazilian evidence-based guideline on the management of hyperglycemia in type 2 diabetes mellitus.

BACKGROUND: In current management of type 2 diabetes (T2DM), cardiovascular and renal prevention have become important targets to be achieved. In this context, a joint panel of four endocrinology societies from Brazil and Portugal was established to develop an evidence-based guideline for treatment of hyperglycemia in T2DM. METHODS: MEDLINE (via PubMed) was searched for randomized clinical trials, meta-analyses, and observational studies related to diabetes treatment. When there was insufficient high-quality evidence, expert opinion was sought. Updated positions on treatment of T2DM patients with heart failure (HF), atherosclerotic CV disease (ASCVD), chronic kidney disease (CKD), and patients with no vascular complications were developed. The degree of recommendation and the level of evidence were determined using predefined criteria. RESULTS AND CONCLUSIONS: In non-pregnant adults, the recommended HbA1c target is below 7%. Higher levels are recommended in frail older adults and patients at higher risk of hypoglycemia. Lifestyle modification is recommended at all phases of treatment. Metformin is the first choice when HbA1c is 6.5-7.5%. When HbA1c is 7.5-9.0%, dual therapy with metformin plus an SGLT2i and/or GLP-1RA (first-line antidiabetic agents, AD1) is recommended due to cardiovascular and renal benefits. If an AD1 is unaffordable, other antidiabetic drugs (AD) may be used. Triple or quadruple therapy should be considered when HbA1c remains above target. In patients with clinical or subclinical atherosclerosis, the combination of one AD1 plus metformin is the recommended first-line therapy to reduce cardiovascular events and improve blood glucose control. In stable heart failure with low ejection fraction (< 40%) and glomerular filtration rate (eGFR) > 30 mL/min/1.73 m2, metformin plus an SGLT-2i is recommended to reduce cardiovascular mortality and heart failure hospitalizations and improve blood glucose control. In patients with diabetes-associated chronic kidney disease (CKD) (eGFR 30-60 mL/min/1.73 m2 or eGFR 30-90 mL/min/1.73 m2 with albuminuria > 30 mg/g), the combination of metformin and an SGLT2i is recommended to attenuate loss of renal function, reduce albuminuria and improve blood glucose control. In patients with severe renal failure, insulin-based therapy is recommended to improve blood glucose control. Alternatively, GLP-1RA, DPP4i, gliclazide MR and pioglitazone may be considered to reduce albuminuria. In conclusion, the current evidence supports individualizing anti-hyperglycemic treatment for T2DM.

Impact of Weight Loss With Intragastric Balloon on Bone Density and Microstructure in Obese Adults.

The historical concept that obesity protects against bone fractures has been questioned. Weight loss appears to reduce bone mineral density (BMD); however, the results in young adults are inconsistent, and data on the effects of weight loss on bone microstructure are limited. This study aimed to evaluate the impact of weight loss using an intragastric balloon (IGB) on bone density and microstructure. Forty obese patients with metabolic syndrome (mean age 35.1 ± 7.3 yr) used an IGB continuously for 6 mo. Laboratory tests, areal BMD, and body composition measurements via dual-energy X-ray absorptiometry, and volumetric BMD and bone microstructure measurements via high-resolution peripheral quantitative computed tomography were conducted before IGB placement and after IGB removal. The mean weight loss was 11.5%. After 6 mo, there were significant increases in vitamin D and carboxyterminal telopeptide of type 1 collagen levels. After IGB use, areal BMD increased in the spine but decreased in the total femur and the 33% radius. Cortical BMD increased in the distal radius but tended to decrease in the distal tibia. The observed trabecular bone loss in the distal tibia contributed to the decline in the total volumetric BMD at this site. There was a negative correlation between the changes in leptin levels and the measures of trabecular quality in the tibia on high-resolutionperipheral quantitative computed tomography. Weight loss may negatively impact bone microstructure in young patients, especially for weight-bearing bones, in which obesity has a more prominent effect.

Combination of basal insulin and GLP-1 receptor agonist: is this the end of basal insulin alone in the treatment of type 2 diabetes?

Glycemic control has been considered a major therapeutic goal within the scope of diabetes management, as supported by robust observational and experimental evidence. However, the coexistence of micro and macrovascular disease is associated with the highest cardiovascular risks which highlights the importance that pharmacological treatment of type 2 diabetes mellitus provides not only glycemic control, but also cardiovascular safety. Basal insulin is a highly effective treatment in reducing fasting blood glucose, but it is associated with considerable risk of hypoglycemia and weight gain. Glucagon like peptide 1 receptor agonists (GLP-1 RAs) are also effective in terms of glycemic control and associated with weight loss and low risk of hypoglycemia. The potential benefits of combining GLP-1RAs with basal insulin are contemplated in the current position statement of several different position statement and guidelines. This article reviews the efficacy and safety of different strategies to initiate and intensify basal insulin, with focus on new fixed ratio combinations of basal insulin with GLP-1 RAs available for use in a single injection pen (insulin degludec/liraglutide and insulin glargine/lixisenatide).

Avaliação dos níveis de albuminúria em adultos obesos e sua associação com marcadores de risco cardiovascular / Albuminuria levels in obese adults and their association with cardiovascular risk markers

Introdução: A obesidade é um dos fatores mais importantes para explicar o aumento incidência das Doenças Cardiovasculares (DCV). Dentre os múltiplos fatores de risco para estas doenças, a albuminúria é dos mais importantes. Objetivos: Avaliar os níveis de albuminúria e correlacionar com outros marcadores de risco cardiovascular em pacientes obesos que procuraram tratamento para obesidade. Materiais e métodos:Estudo transversal, retrospectivo, através dos prontuários de 183 pacientes de ambos os sexos, entre 18 e 65 anos, com índice de massa corpórea (IMC) ≥ 30 Kg/m². Todos os pacientes foram submetidos a exame físico e receberam um pedido de rotina laboratorial, incluindo de albuminúria em amostra isolada de urina. Valores até 17 mg/L foram considerados normoalbuminúria, de 17-173 mg/L microalbuminuria e ≥ 174mg/L macroalbuminúria. A análise de correlação de Pearson ou Spearman foi utilizada para correlacionar os níveis de albuminuria com as variáveis antropométricas e laboratoriais. Resultados: Dados de albuminúria estavam disponíveis em 81 prontuários. Destes, 15 pacientes (18,5%) tinham valores acima de 17 mg/L de albuminúria. Nenhuma correlação foi encontrada entre os níveis de albuminúria e os parâmetros antropométricos (IMC, Cintura, Quadril e RCQ), pressão arterial (PA) sistólica ou diastólica ou uso de anti-hipertensivos. Foi encontrada correlação entre os níveis de albuminúria e o high-density lipoprotein cholesterol (HDLc), (r=-0,27; p=0,012), além de uma tendência a significância com os níveis de Proteína C Reativa Ultrassensível (PCR-us; r=0,21; p= 0,081). Conclusão: Apesar da alta frequência de albuminúria em pacientes obesos, não foi encontrada correlação entre este marcador e os parâmetros antropométricos. Foi encontrado uma relação inversa da albuminúria com HDLc e uma tendência a significância com a PCR-us, sugerindo uma associação limitada entre a albuminúria e alguns marcadores específicos de risco cardiovascular.

Introduction: Obesity is one of the most important factors related to the increase in Cardiovascular Diseases (CVD) incidence. Among all risk factors for CVD, albuminuria is one of the most relevant. Objective:To evaluate the levels of albuminuria and to correlate with other cardiovascular risk markers in obese patients who seek treatment for obesity. Material and Methods: A retrospective cross-sectional study of 183 patients of both genders, aged 18-65 years, with a body mass index (BMI) ≥ 30 kg / m², attended for the first time. All the patients were submitted to a physical exam and received a routine laboratory request, including for the concentration of albumin in the urine. Values below 17 mg/L were considered normoalbuminuria, from 17 to 173 mg/dL microalbuminuria and above 174 macroalbuminuria. Pearson ou Spearman Correlation was used to correlate albuminuria levels with anthropometric and laboratorial variables. Results: Excluding 102 patient charts out of the criteria, the results of 81 patients were considered. Of these, 15 patients (18.5%) had values above 17 mg / L of albuminuria. No correlation was found between albuminuria levels and anthropometric parameters (BMI, Waist, Hip), systolic BP, diastolic BP or antihypertensive use. A significant correlation was found between albuminuria levels and high-density lipoprotein cholesterol (HDLc), (r = -0.27, p = 0.012), and a trend toward significance with hs-CRP levels (r = 0, 21, p = 0.081). Conclusion: Despite the high prevalence of albuminuria in obese patients, no correlation was found between anthropometric markers and albuminuria. An inverse relationship was found for albuminuria with HDLc, and a trend toward significance with hs-CRP, suggesting a limited association between albuminuria and some specific markers of cardiovascular risk.

Diretriz brasileira baseada em evidências sobre prevenção de doenças cardiovasculares em pacientes com diabetes: posicionamento da Sociedade Brasileira de Diabetes (SBD), da Sociedade Brasileira de Cardiologia (SBC) e da Sociedade Brasileira de Endocrinologia e Metabologia (SBEM) / Brazilian evidence-based guideline on cardiovascular disease prevention in patients with diabetes: positioning of the Brazilian Society of Diabetes (SBD), the Brazilian Society of Cardiology (SBC) and the Brazilian Society of Endocrinology and Metabology (SBEM)

Resumo Fundamentação: desde o primeiro posicionamento da Sociedade Brasileira de Diabetes (SBD) sobre diabetes e prevenção cardiovascular, em 2014,1 importantes estudos têm sido publicados na área de prevenção cardiovascular e tratamento do diabetes,2 os quais contribuíram para a evolução na prevenção primária e secundária nos pacientes com diabetes. Ferramentas de estratificação de risco mais precisas, novos fármacos hipolipemiantes e novos antidiabéticos com efeitos cardiovasculares e redução da mortalidade, são parte desta nova abordagem para os pacientes com diabetes. O reconhecimento de que o diabetes é uma doença heterogênea foi fundamental, sendo claramente demonstrado que nem todos os pacientes diabéticos pertencem a categorias de risco alto ou muito alto. Um porcentual elevado é composto por pacientes jovens, sem os fatores de risco clássicos, os quais podem ser classificados adequadamente em categorias de risco intermediário ou mesmo em baixo risco cardiovascular. O presente posicionamento revisa as melhores evidências atualmente disponíveis e propõe uma abordagem prática, baseada em risco, para o tratamento de pacientes com diabetes. Estruturação: perante este desafio e reconhecendo a natureza multifacetada da doença, a SBD uniu-se à Sociedade Brasileira de Cardiologia (SBC) e à Sociedade Brasileira de Endocrinologia e Metabolismo (SBEM), e formou um painel de especialistas, constituído por 28 cardiologistas e endocrinologistas, para revisar as melhores evidências disponíveis e elaborar uma diretriz contendo recomendações práticas para a estratificação de risco e prevenção da Doença Cardiovascular (DVC) no Diabetes Melito (DM). As principais inovações incluem: (1) considerações do impacto de novos hipolipemiantes e das novas medicações antidiabéticas no risco cardiovascular; (2) uma abordagem prática, baseada em fator de risco, para orientar o uso das estatinas, incluindo novas definições das metas da Lipoproteína de Baixa Densidade-colesterol (LDL-colesterol) e colesterol não Lipoproteína de Alta Densidade HDL; (3) uma abordagem baseada em evidências, para avaliar a isquemia miocárdica silenciosa (IMS) e a aterosclerose subclínica em pacientes com diabetes; (4) as abordagens mais atuais para o tratamento da hipertensão; e (5) recomendação de atualizações para o uso de terapia antiplaquetária. Esperamos que esta diretriz auxilie os médicos no cuidado dedicado aos pacientes com diabetes. Métodos: inicialmente, os membros do painel foram divididos em sete subcomitês para definirem os tópicos principais que necessitavam de uma posição atualizada das sociedades. Os membros do painel pesquisaram e buscaram no PubMed estudos clínicos randomizados e metanálises de estudos clínicos e estudos observacionais de boa qualidade, publicados entre 1997 e 2017, usando termos MeSH: [diabetes], [diabetes tipo 2], [doença cardiovascular], [estratificação de risco cardiovascular] [doença arterial coronária], [rastreamento], [isquemia silenciosa], [estatinas], [hipertensão], [ácido acetilsalicílico]. Estudos observacionais de baixa qualidade, metanálises com alta heterogeneidade e estudos transversais não foram incluídos, embora talvez tenham impactado no Nível de Evidência indicado. A opinião de especialistas foi usada quando os resultados das buscas não eram satisfatórios para um item específico. É importante salientar que este posicionamento não teve a intenção de incluir uma revisão sistemática rigorosa. Um manuscrito preliminar, destacando recomendações de graus e níveis de evidência (Quadro 1), foi esboçado. Este passo levou a várias discussões entre os membros dos subcomitês, que revisaram os achados e fizeram novas sugestões. O manuscrito foi, então, revisto pelo autor líder, encarregado da padronização do texto e da inclusão de pequenas alterações, sendo submetido à apreciação mais detalhada pelos membros dos comitês, buscando uma posição de consenso. Depois desta fase, o manuscrito foi enviado para a banca editorial e edição final, sendo encaminhado para publicação. Quadro 1 Graus de recomendações e níveis de evidências adotados nesta revisão Grau de recomendação Classe I A evidência é conclusiva ou, se não, existe consenso de que o procedimento ou tratamento é seguro e eficaz Classe II Há evidências contraditórias ou opiniões divergentes sobre segurança, eficácia, ou utilidade do tratamento ou procedimento Classe IIa As opiniões são favoráveis ao tratamento ou procedimento. A maioria dos especialistas aprova Classe IIb A eficácia é bem menos estabelecida, e as opiniões são divergentes Classe III Há evidências ou consenso de que o tratamento ou procedimento não é útil, eficaz, ou pode ser prejudicial Níveis de Evidência A Múltiplos estudos clínicos randomizados concordantes e bem elaborados ou metanálises robustas de estudos clínicos randomizados B Dados de metanálises menos robustas, um único estudo clínico randomizado ou estudos observacionais C Opinião dos especialistas

Impact of 6 months of treatment with intragastric balloon on body fat and quality of life in obese individuals with metabolic syndrome.

BACKGROUND: Obesity is a worldwide public health issue with a negative impact on quality of life. Different weight loss interventions have demonstrated improvements in quality of life. The aim of this study was to investigate the effect of 6 months of treatment with an intragastric balloon (IGB) on health-related quality of life (HRQOL) and its relation to changes in body fat in obese individuals with metabolic syndrome (MS). METHODS: Fifty obese patients with MS aged 18-50 were selected for treatment with IGB for 6 months. Body fat was assessed with anthropometric measures and dual-energy X-ray absorptiometry (DXA) at baseline and after removal of the IGB. HRQOL was evaluated with the short form of the World Health Organization Quality of Life (WHOQOL-BREF) at baseline and soon after removal of the IGB. RESULTS: Thirty-nine patients completed the study. After 6 months, there was a significant improvement in quality of life (p = 0.0009) and health (p < 0.0001) perceptions, and in the Physical (p = 0.001), Psychological (p = 0.031), and Environmental domains (p = 0.0071). Anthropometric measures and total fat determined by DXA were directly and significantly related to an improvement in general aspects of quality of life. The decrease in the percentage of total fat was the parameter that better correlated with improvements in quality of life perception after regression (p = 0.032). CONCLUSIONS: In obese individuals with MS, weight loss parameters were associated with short-term improvements in HRQOL after 6 months of treatment with IGB. However, only total fat was independently related to HRQOL perception. TRIAL REGISTRATION: ClinicalTrials.gov NCT01598233 .

Correlation between parameters of self-monitoring of blood glucose and the perception of health-related quality of life in patients with type 1 diabetes mellitus

ABSTRACT Objective The aim of this study was to evaluate how different parameters of short-term glycemic control would correlate with the perception of health-related quality of life (HRQoL) in patients with type 1 diabetes mellitus (T1D). Subjects and methods A total of 50 T1D patients aged 18 to 50 years were evaluated with the questionnaires Problem Areas in Diabetes (PAID) scale and Diabetes Quality of Life (DQOL) measure after 30 days of self-monitoring of blood glucose (SMBG). Glycemic control was evaluated using glycated hemoglobin (HbA1c), mean glucose levels (MGL) in the prior month's data from SMBG (Accu-Check 360o), number of hypoglycemic episodes (< 70 mg/dL and < 50 mg/dL), and glycemic variability (GV). Results PAID correlated positively with MGL (r = 0.52; p < 0.001) and HbA1c (r = 0.36; p < 0.0097), but not with GV (r = 0.17; p = 0.23) or number of hypoglycemic episodes (r = 0.15; p = 0.17 for glucose < 70 mg/dL and r = 0.02; p = 0.85 for glucose < 50 mg/dL). After multiple linear regression, only MGL remained independently related to PAID scores. DQOL scores had a positive correlation with MGL (r = 0.45; p = 0.001), but not with HbA1c (r = 0.23; p = 0.09), GV (r = 0.20; p = 0.16), or number of hypoglycemic episodes (r = 0.06 p = 0.68). Conclusion In T1D patients, MGL, but not HbA1c or number hypoglycemic episodes, was the glycemic control parameter that best correlated with short-term perception of HRQoL.

Brazilian guidelines on prevention of cardiovascular disease in patients with diabetes: a position statement from the Brazilian Diabetes Society (SBD), the Brazilian Cardiology Society (SBC) and the Brazilian Endocrinology and Metabolism Society (SBEM).

BACKGROUND: Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. MAIN BODY: The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. CONCLUSIONS: Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in individuals in the highest risk as well as protection from overtreatment in those at lower risk. Thus, cardiovascular prevention strategies should be individualized according to cardiovascular risk while intensification of treatment should focus on those at higher risk.

Dipeptidyl peptidase-4 levels are increased and partially related to body fat distribution in patients with familial partial lipodystrophy type 2.

BACKGROUND: Dipeptidyl peptidase-4 (DDP4) is an enzyme responsible for glucagon-like peptide-1 inactivation and plays an important role in glucose metabolism. OBJECTIVE: The aim of this study was to evaluate DPP4 levels in patients with familial partial lipodystrophy type 2 (FPLD2) and correlate it with body fat distribution. METHODS: Fourteen patients with FPLD2 were selected to participate in this study and matched to a healthy control group (n = 8). All participants had anthropometrical data registered. Body adiposity index (BAI) was used to evaluate fat distribution in this population. Body fat content and distribution were analyzed by dual X-ray absorptiometry (DXA). Biochemical exams, including DPP4 levels, were performed in all individuals. RESULTS: Despite the same body mass index, lipodystrophic patients had a significant lower hip (median 92.0 vs 94.5; p = 0.028), HDL cholesterol (42.6 ± 10.4 vs 66.1 ± 16.0; p < 0.01) and BAI (24.1 ± 2.8 vs 29.0 ± 3.7; p = 0.02), suggesting that BAI was able to catch differences in fat distribution between groups. On the other hand, patients with FPLD2 presented significant higher levels of insulin (median 11.2 vs 5.3; p = 0.015), triglycerides (184.9 ± 75.4 vs 89.1 ± 51.0; p < 0.01) and DPP4 (4.89 ± 0.92 vs 3.93 ± 1.08; p = 0.04). A trend toward an inverse statistical significance was observed between DPP4 levels and BAI (r = -0.38; p = 0.072). In the lipodistrophic group, a significant correlation was found between DPP4 levels and percentage of total body fat (r = 0.86; p = 0.0025) and android fat (r = 0.78; p = 0.014). CONCLUSIONS: Patients with FPLD2 exhibit an increase in DDP4 levels in comparison to a healthy control group. The increase in the levels of this enzyme does not seem to be related to the diagnosis of diabetes and might be associated with an increase in central fat (estimated using BAI and measured using DXA). These results might be used to reinforce the concept that DDP4 is an adipokine related to central fat distribution.

Correlation between parameters of self-monitoring of blood glucose and the perception of health-related quality of life in patients with type 1 diabetes mellitus.

OBJECTIVE: The aim of this study was to evaluate how different parameters of short-term glycemic control would correlate with the perception of health-related quality of life (HRQoL) in patients with type 1 diabetes mellitus (T1D). SUBJECTS AND METHODS: A total of 50 T1D patients aged 18 to 50 years were evaluated with the questionnaires Problem Areas in Diabetes (PAID) scale and Diabetes Quality of Life (DQOL) measure after 30 days of self-monitoring of blood glucose (SMBG). Glycemic control was evaluated using glycated hemoglobin (HbA1c), mean glucose levels (MGL) in the prior month's data from SMBG (Accu-Check 360o), number of hypoglycemic episodes (< 70 mg/dL and < 50 mg/dL), and glycemic variability (GV). RESULTS: PAID correlated positively with MGL (r = 0.52; p < 0.001) and HbA1c (r = 0.36; p < 0.0097), but not with GV (r = 0.17; p = 0.23) or number of hypoglycemic episodes (r = 0.15; p = 0.17 for glucose < 70 mg/dL and r = 0.02; p = 0.85 for glucose < 50 mg/dL). After multiple linear regression, only MGL remained independently related to PAID scores. DQOL scores had a positive correlation with MGL (r = 0.45; p = 0.001), but not with HbA1c (r = 0.23; p = 0.09), GV (r = 0.20; p = 0.16), or number of hypoglycemic episodes (r = 0.06 p = 0.68). CONCLUSION: In T1D patients, MGL, but not HbA1c or number hypoglycemic episodes, was the glycemic control parameter that best correlated with short-term perception of HRQoL.

Brazilian guidelines on prevention of cardiovascular disease in patients with diabetes: a position statement from the Brazilian Diabetes Society (SBD), the Brazilian Cardiology Society (SBC) and the Brazilian Endocrinology and Metabolism Society (SBEM)

BACKGROUND: Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. MAIN BODY: The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy.

Serum TSH levels are associated with cardiovascular risk factors in overweight and obese adolescents / Níveis de TSH sérica associados a fatores de risco cardiovascular em adolescentes acima do peso e obesos

Abstract Objective: To investigate the relationship between serum thyrotropin (TSH), insulin resistance (IR), and cardiovascular risk factors (CRF) in a sample of overweight and obese Brazilian adolescents. Methods: A retrospective, longitudinal analysis of 199 overweight and obese pubescent adolescents was performed. The TSH and free T4 (fT4) levels, anthropometric measurements, and laboratory test results of these patients were analyzed. Results: 27 individuals (13.56%) presented with TSH levels above the normal level (subclinical hypothyroidism [SCH]). Their waist circumference (WC) was significantly higher than those of euthyroid individuals. Serum TSH was positively correlated with the homeostasis model assessment of insulin resistance (HOMA-IR) index, triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C). Using TSH and BMI as independent variables, TSH levels were shown to be independently related to HOMA-IR (p = 0.001) and TG (p = 0.007). Among euthyroid subjects, individuals with TSH values <2.5 mIU/mL exhibited statistically significant decreases in waist-to-hip ratio, HDL-C levels, and HOMA-IR scores and a tendency toward lower WC values. Conclusion: SCH in overweight and obese adolescents appears to be associated with excess weight, especially visceral weight. In euthyroid adolescents, there appears to be a direct relationship between TSH and some CRF. In conclusion, in the present sample of overweight and obese adolescents, TSH levels appear to be associated with IR and CRF.

Resumo Objetivo Investigar a relação entre tireotrofina sérica (TSH), resistência à insulina (RI) e fatores de risco cardiovascular (FRC) em uma amostra de adolescentes brasileiros acima do peso e obesos. Métodos Foi realizada uma análise longitudinal retrospectiva de 190 adolescentes púberes acima do peso e obesos. Foram analisados os níveis de TSH e T4 livre (T4l), as medidas antropométricas e os resultados de exames laboratoriais desses pacientes. Resultados 27 indivíduos (13,56%) apresentaram níveis de TSH acima do normal (hipotireoidismo subclínico (HSC)). Eles apresentaram circunferência da cintura (CC) significativamente maior que os indivíduos eutireoideos. A TSH sérica foi positivamente correlacionada ao índice do modelo de avaliação da homeostase de resistência à insulina (HOMA-IR), triglicerídeos (TG) e lipoproteína de alta densidade-colesterol (HDL-C). Usando TSH e IMC como variáveis independentes, os níveis de TSH estavam relacionados ao HOMA-IR (p = 0.001) e a TG (p = 0.007) de forma independente. Entre os pacientes eutireoideos, indivíduos com valores de TSH < 2.5 mIU/mL apresentaram reduções estatisticamente significativas na razão cintura/quadril, nos níveis de HDL-C e nos escores de HOMA-IR e tendência a menores valores de CC. Conclusão O HSC em adolescentes acima do peso e obesos parece estar associado ao excesso de peso, principalmente de peso visceral. Em adolescentes eutireoideos, parece haver uma relação direta entre TSH e alguns FRC. Concluindo, em nossa amostra de adolescentes acima do peso e obesos, os níveis de TSH parecem estar associados a RI e FRC.
