Real-world treatment patterns and disease control over one year in patients with inflammatory bowel disease in Brazil.

BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBDs) with a remission-relapsing presentation and symptomatic exacerbations that have detrimental impacts on patient quality of life and are associated with a high cost burden, especially in patients with moderate-to-severe disease. The Real-world Data of Moderate-to-Severe Inflammatory Bowel Disease in Brazil (RISE BR) study was a noninterventional study designed to evaluate disease control, treatment patterns, disease burden and health-related quality of life in patients with moderate-to-severe active IBD. We report findings from the prospective follow-up phase of the RISE BR study in patients with active UC or CD. AIM: To describe the 12-mo disease evolution and treatment patterns among patients with active moderate-to-severe IBD in Brazil. METHODS: This was a prospective, noninterventional study of adult patients with active Crohn's disease (CD: Harvey-Bradshaw Index ≥ 8, CD Activity Index ≥ 220), inadequate CD control (i.e., calprotectin > 200 µg/g or colonoscopy previous results), or active ulcerative colitis (UC: Partial Mayo score ≥ 5). Enrollment occurred in 14 centers from October 2016 to February 2017. The proportion of active IBD patients after 9-12 mo of follow-up, Kaplan-Meier estimates of the time to mild or no activity and a summary of treatment initiation, discontinuation and dose changes were examined. RESULTS: The study included 118 CD and 36 UC patients, with mean ± SD ages of 43.3 ± 12.6 and 44.9 ± 16.5 years, respectively. The most frequent drug classes at index were biologics for CD (62.7%) and 5-aminosalicylate derivates for UC patients (91.7%). During follow-up, 65.3% of CD and 86.1% of UC patients initiated a new treatment at least once. Discontinuations/dose changes occurred in 68.1% of CD patients [median 2.0 (IQR: 2-5)] and 94.3% of UC patients [median 4.0 (IQR: 3-7)]. On average, CD and UC patients had 4.4 ± 2.6 and 5.0 ± 3.3 outpatient visits, respectively. The median time to first mild or no activity was 319 (IQR: 239-358) d for CD and 320 (IQR: 288-358) d for UC patients. At 9-12 mo, 22.0% of CD and 20.0% of UC patients had active disease. CONCLUSION: Although a marked proportion of active IBD patients achieved disease control within one year, the considerable time to achieve this outcome represents an unmet medical need of the current standard of care in a Brazilian real-world setting.

Real-world disease activity and sociodemographic, clinical and treatment characteristics of moderate-to-severe inflammatory bowel disease in Brazil.

BACKGROUND: Understanding the treatment landscape of inflammatory bowel diseases (IBD) is essential for improving disease management and patient outcomes. Brazil is the largest Latin American country, and it presents socioeconomic and health care differences across its geographical regions. This country has the highest increase in IBD incidence and prevalence in Latin America, but information about the clinical and treatment characteristics of IBD is scarce. AIM: To describe the sociodemographic, clinical, and treatment characteristics of IBD outpatients in Brazil overall and in the Southeast, South and Northeast/Midwest regions. METHODS: Multicenter, cross-sectional study with a 3-year retrospective chart review component. Patients with moderate-to-severe Crohn's disease (CD) or ulcerative colitis (UC) were consecutively enrolled between October 2016 and February 2017. Active CD at enrollment was defined as a Harvey Bradshaw Index ≥ 8 or a CD Activity Index ≥ 220 or a calprotectin level > 200 µg/g or an active result based on colonoscopy suggestive of inadequate control during the previous year; active UC was defined as a partial Mayo score ≥ 5. Descriptive statistics were used to analyze all variables. RESULTS: In a total of 407 included patients, CD was more frequent than UC, both overall (264 CD/143 UC patients) and by region (CD:UC ratios of 2.1 in the Southeast, 1.6 in the South and 1.2 in the Northeast/Midwest). The majority of patients were female (54.2% of CD; 56.6% of UC), and the mean ages were 45.9 ± 13.8 years (CD) and 42.9 ± 13.0 years (UC). The median disease duration was 10.0 (range: 0.5-45) years for both IBD types. At enrollment, 44.7% [95% confidence interval (CI): 38.7-50.7] of CD patients and 25.2% (95%CI: 18.1-32.3) of UC patients presented with active disease. More than 95% of IBD patients were receiving treatment at enrollment; CD patients were commonly treated with biologics (71.6%) and immunosuppressors (67.4%), and UC patients were commonly treated with mesalazine [5-Aminosalicylic acid (5-ASA)] derivates (69.9%) and immunosuppressors (44.1%). More than 50% of the CD patients had ileocolonic disease, and 41.7% presented with stricturing disease. One-quarter of CD patients had undergone CD-related surgery in the past 3 years, and this proportion was lower in the Northeast/Midwest region (2.9%). CONCLUSION: In Brazil, there are regional variations in IBD management. CD outweighs UC in both frequency and disease activity. However, one-quarter of UC patients have active disease, and most are receiving 5-ASA treatment.

Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil.

BACKGROUND: Inflammatory bowel diseases (IBD) have been associated with a low quality of life (QoL) and a negative impact on work productivity compared to the general population. Information about disease control, patient-reported outcomes (PROs), treatment patterns and use of healthcare resources is relevant to optimizing IBD management. AIM: To describe QoL and work productivity and activity impairment (WPAI), treatment patterns and use of healthcare resources among IBD patients in Brazil. METHODS: A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn's disease (CD) or ulcerative colitis (UC). At enrolment, active CD and UC were defined as having a Harvey Bradshaw Index ≥ 8 or a CD Activity Index ≥ 220 or calprotectin > 200 µg/g or previous colonoscopy results suggestive of inadequate control (per investigator criteria) and a 9-point partial Mayo score ≥ 5, respectively. The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L, the Inflammatory Bowel Disease Questionnaire (IBDQ), and the WPAI questionnaire. Information about healthcare resources and treatment during the previous 3 years was collected from medical records. Chi-square, Fisher's exact and Student's t-/Mann-Whitney U tests were used to compare PROs, treatment patterns and the use of healthcare resources by disease activity (α = 0.05). RESULTS: Of the 407 patients in this study (CD/UC: 64.9%/35.1%, mean age 42.9/45.9 years, 54.2%/56.6% female, 38.3%/37.1% employed), 44.7%/25.2% presented moderate-to-severe CD/UC activity, respectively, at baseline. Expressed in median values for CD/UC, respectively, the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2, the EQ-visual analog scale score was 80.0/70.0, and the IBDQ overall score was 164.0/165.0. Moderate to severe activity, female gender, being unemployed, a lower educational level and lower income were associated with lower QoL (P < 0.05). Median work productivity impairment was 20% and 5% for CD and UC patients, respectively, and activity impairment was 30%, the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity (75.0% vs 10.0%, P < 0.001). For CD/UC patients, respectively, 25.4%/2.8% had at least one surgery, 38.3%/19.6% were hospitalized, and 70.7%/77.6% changed IBD treatment at least once during the last 3 years. The most common treatments at baseline were biologics (75.3%) and immunosuppressants (70.9%) for CD patients and 5-ASA compounds (77.5%) for UC patients. CONCLUSION: Moderate to severe IBD activity, especially among CD patients, is associated with a substantial impact on QoL, work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil.

[Low levels of 25-hydroxyvitamin D (25OHD) in patients with inflammatory bowel disease and its correlation with bone mineral density]. / Níveis baixos de 25-hidroxivitamina D (25OHD) em pacientes com doença inflamatória intestinal e sua correlação com a densidade mineral óssea.

UNLABELLED: Patients with inflammatory bowel disease (IBD) are at risk of having vitamin D deficiency (25-OHD) and low bone mineral density (BMD). OBJECTIVES: To measure 25OHD in a young group of IBD patients submitted to a clinical evaluation, routine biochemistry and BMD measurement (lumbar spine and proximal femur). RESULTS: 39 Crohn disease (CD) and 37 ulcerative colitis (UC) patients had lower serum levels of 25OHD compared to the control group (CD p = 0.003; UC p < 0.001), and 48.5% of the UC patients were 25OHD deficient. Lumbar spine BMD was lower in patients than controls (CD p = 0.001; UC p = 0.008). In CD patients, serum levels of 25OHD were significantly correlated with total femur (r = 0.391; p = 0.027) and femoral neck (r = 0.384; p = 0.03) BMD. CONCLUSION: It was found lower levels of 25OHD and BMD in young IBD patients compared to normal controls, suggesting an important role of 25OHD deficiency in the pathogenesis of the IBD bone disease.

INTRODUÇÃO: Pacientes com doenças inflamatórias intestinais (DII) estão propensos a apresentar níveis baixos de vitamina D (25OHD) e densidade mineral óssea (DMO) diminuída. OBJETIVO: Verificar o nível de 25OHD em jovens com DII submetidos à avaliação clínica, dosagens bioquímicas rotineiras e medida da DMO de coluna lombar e fêmur, comparando-os com controles saudáveis. RESULTADOS: 39 pacientes com doença de Crohn (DC) (p = 0, 003) e 37 com retocolite ulcerativa inespecífica (RCUI) (p < 0,001) apresentaram níveis mais baixos de 25OHD comparados aos controles, 48,5 por cento dos pacientes com RCUI tinham deficiência de 25OHD. A DMO em coluna lombar foi mais baixa nos doentes (DC p = 0,001; RCUI p = 0,008). A 25OHD correlacionou-se significativamente com a DMO do fêmur total (r = 0,391; p = 0,027) e colo do fêmur (r = 0,384; p = 0,03) na DC. CONCLUSÃO: Foram encontrados níveis baixos de 25OHD e DMO em jovens com DII, sugerindo papel importante desta deficiência na patogênese da doença óssea desses pacientes.

Correlação das características do ecodoppler do sistema porta com presença de alterações endoscópicas secundárias à hipertensão porta em pacientes com cirrose hepática / Correlation of Doppler ultrasound of the portal system with endoscopic changes caused by portal hypertension in cirrhotic patients / Correlation of Doppler ultrasound of the portal system with endoscopic changes caused by portal hypertension in cirrhotic patients

RACIONAL: A hipertensão portal é a causa principal das complicações da cirrose hepática, traduzidas clinicamente por circulação colateral visível na parede abdominal, ascite e varizes esofágicas. OBJETIVO: Avaliar a capacidade do ecodoppler do sistema porta no diagnóstico de alterações esôfago-gástricas endoscópicas secundárias à hipertensão porta em pacientes com cirrose hepática. PACIENTES E MÉTODOS: Cento e oitenta e seis pacientes dos ambulatórios de gastroenterologia e hepatologia do Hospital de Clínicas da Universidade Federal do Paraná, Curitiba, PR, foram selecionados para avaliação. Destes, 145 completaram todas as etapas e 133 puderam ser incluídos na análise final dos dados. Todos foram submetidos a endoscopia digestiva alta, visando determinar presença e grau de varizes esofágicas e gástricas e de gastropatia congestiva e ao ecodoppler do sistema porta para medir/aferir pico de velocidade sistólica da veia porta, diâmetro das veias porta e esplênica, tamanho do baço, presença de recanalização da veia umbilical e de fluxo hepatofugal. RESULTADOS: Os pacientes com varizes esofágicas e gástricas tiveram diferença significativa do tamanho do baço quando comparados com os pacientes sem essas alterações. No entanto, a exatidão e a especificidade deste parâmetro não foi adequada. O diagnóstico de gastropatia congestiva pode ser predito de maneira significativa, tanto pelo diâmetro da veia porta, quanto pelo da esplênica e também pelo tamanho do baço. Da mesma forma, todavia, a exatidão e especificidade destes parâmetros foram ruins. As medidas foram validadas pela construção de curvas ROC ("Receiver Operating Characteristic"), cujas áreas sob as curvas foram sempre menores que 0,8. CONCLUSÃO: Nesta série de pacientes não houve boa correlação dos parâmetros do ecodoppler do sistema porta com a presença das principais alterações endoscópicas (varizes esofágicas, varizes gástricas, gastropatia congestiva) em pacientes com cirrose hepática.

BACKGROUND: The portal hypertension in cirrhotic patients is the main cause of this illness complication, that are clinically translated to visible collateral circulation in the abdominal wall, ascites and esophageal varices. AIM: To evaluate if the portal system echodoppler is able to estimate the presence of esophageal varices, gastric varices and congestive gastropathy in patients with hepatic cirrhosis. PATIENTS AND METHODS: One hundred and eighty six patients of the gastroenterology and hepatology ambulatory of the Clinical Hospital of the Federal University of Paraná, Curitiba, PR, Brazil, had been selected for evaluation. Of those, 145 had completed all the stages of the evaluation and 133 had been enclosed in the final analysis. All had been submitted to high digestive endoscopy for evaluation of esophagogastric varices and congestive gastropathy and then to Doppler ultrasound of the portal system with study of the systolic peak speed of the portal vein, diameter of the portal and splenic vein and spleen size, presence of the umbilical vein recanalization and hepatofugal flow. RESULTS: The patients with esophagogastric varices had significant difference of the spleen size when compared to patients without these change. However, none of the Doppler ultrasound parameters showed good accuracy and specificity in this group of cirrhotic patients. Congestive gastropathy patients had their diagnosis predict with significant manner not only by the portal and splenic vein diameter but also by the spleen size. Similarly to that described above, they do not have a good accuracy and specificity. These evaluations were validated by the construction of ROC (Receiver Operating Characteristic) curves, whose areas below the curves had always been less than 0,8. CONCLUSION: There was not a good correlation of the Doppler ultrasound parameters of the portal system to the presence of the main endoscopic alterations (esophagogastric varices and congestive gastropathy) in ...

Avaliação da densidade mineral óssea em pacientes com doença inflamatória intestinal / Bone mineral density evaluation in inflammatory bowel disease patients

RACIONAL: Pacientes com doença inflamatória intestinal têm maior prevalência de redução da densidade mineral óssea em comparação às pessoas saudáveis. OBJETIVO: Avaliar a densidade mineral óssea em uma população de pacientes com doença inflamatória intestinal. MÉTODOS: Noventa pacientes de 20 a 50 anos de idade, do ambulatório de doença inflamatória intestinal do Serviço de Gastroenterologia do Hospital de Clínicas da Universidade Federal do Paraná, Curitiba, PR, foram selecionados para avaliação. Desses, 76 completaram todas as etapas de avaliação. A densitometria foi realizada da coluna lombar e fêmur direito em aparelho Hologyc QDR 1000/W. RESULTADOS: Os pacientes com doença inflamatória intestinal tiveram significativa redução da densidade mineral óssea, avaliada por massa óssea em números absolutos (g/cm²), em todas as regiões avaliadas, colo do fêmur, fêmur total e coluna lombar. As variáveis analisadas como, índice de atividade de doença, uso de corticóide, cirurgias prévias, índice de massa corpórea e falta de atividade física, não demonstraram correlação com a massa óssea, ou seja, não influenciaram os resultados da densidade mineral óssea no grupo estudado de doentes com doença inflamatória intestinal. CONCLUSÃO: Densidade mineral óssea reduzida foi encontrada nos pacientes com doença inflamatória intestinal do Ambulatório de Doença Inflamatória Intestinal do Serviço de Gastroenterologia do Hospital de Clínicas da Universidade Federal do Paraná, mais pronunciadamente nos pacientes com doença de Crohn, semelhante ao descrito na literatura. Nenhuma das variáveis analisadas mostrou correlação com a densidade mineral óssea.

[Bone mineral density evaluation in inflammatory bowel disease patients]. / Avaliação da densidade mineral óssea em pacientes com doença inflamatória intestinal.

BACKGROUND: Inflammatory bowel disease patients have shown greater reduction of the bone mineral density compared to healthy people. AIM: To evaluate the bone mineral density in a population of patients with inflammatory bowel disease. METHODS: Ninety patients from 20 to 50 years old, of the Inflammatory Bowel Disease Ambulatory of the Gastroenterology Service of the Clinics Hospital, Curitiba, PR, Brazil, were selected for the evaluation. From those, 76 completed all the stages of the evaluation. The densitometry was made from lumbar column and right femur with a dual-energy x-ray absorptiometry (Hologyc QDR 1000/W) device. RESULTS: The inflammatory bowel disease patients had a significant reduction of the bone mineral density in all the evaluated parts, femur neck, total femur and lumbar column. The analysed variables, disease activity index, usage of corticoids, the lack of physical activities, the index body mass and previous surgeries did not have influence in the results. CONCLUSION: Reduced bone mineral density was founded in inflammatory bowel disease patients of the Clinics Hospital, mainly in the Crohn's disease patients, as described in literature. None analyzed variables had significant correlation to the bone mineral density.
