WARNING TO DELAY IN DIAGNOSING MICROSCOPIC COLITIS IN OLDER ADULTS. A SERIES OF CASES.

BACKGROUND: Microscopic colitis (MC) is a chronic inflammatory bowel disease causing non-bloody diarrhea, and several cases are undiagnosed as a hidden cause of chronic diarrhea. OBJECTIVE: We aimed to report the symptoms, delay diagnosis and the treatment of MC in a case series. METHODS: All patients were treated at a Gastroenterology reference office from May 2022 to June 2023. Personal history including preexisting disorders, use of medications and smoking habits were collected. The delay between the onset of symptoms and the correct diagnosis was informed. All patients consented to use budesonide MMX (Corament®) off label. RESULTS: During the study period, six Caucasoid patients were diagnosed with MC, five females and one male, between the ages of 65 and 74. All patients had comorbities and were taking multiple prescription drugs. Laboratory findings showed negative serology for celiac disease for all patients, normal levels of albumin and vitamin B12. The delay between the symptoms and the MC diagnosis varied from 2 months to 6 years. All patients had a previous diagnosis of irritable bowel syndrome. All patients were in complete clinical remission during the treatment and referred no side effects of the drug. CONCLUSION: Older females using high-risk medications are suggestive of MC. Preventing delay in the diagnosis of MC is crucial to improvement in patients´ quality of life. Budesonide MMX appears to be effective, safe and well-tolerated. BACKGROUND: • Microscopic Colitis is a chronic inflammatory bowel disease causing non-bloody diarrhea. BACKGROUND: • Several cases are undiagnosed and can be a hidden cause of chronic diarrhea. BACKGROUND: • Treatment with budesonide MMX (Corament®, off label) was effective and safe.

RESUMO Contexto: A colite microscópica (CM) é uma doença inflamatória intestinal crônica que causa diarreia não sanguinolenta, e vários casos não são diagnosticados como uma causa oculta de diarreia crônica. Objetivo: Esse estudo visou relatar os sintomas, qual o atraso diagnóstico e o tratamento da CM em uma série de casos. Métodos: Todos os pacientes foram atendidos em um consultório de referência em Gastroenterologia no período de maio de 2022 a junho de 2023. Foram coletados antecedentes pessoais, incluindo distúrbios preexistentes, uso de medicamentos e tabagismo. Foi buscado o período entre o início dos sintomas e o diagnóstico correto. Todos os pacientes consentiram em usar budesonida MMX (Corament®) off label. Resultados: Durante o período do estudo, seis pacientes caucasóides foram diagnosticados com CM, cinco mulheres e um homem, com idades entre 65 e 74 anos. Todos os pacientes apresentavam comorbidades e faziam uso de vários medicamentos prescritos. Os achados laboratoriais mostraram sorologia negativa para doença celíaca em todos os pacientes, níveis normais de albumina e vitamina B12. O atraso entre os sintomas e o diagnóstico de CM variou de 2 meses a 6 anos. Todos os pacientes tinham diagnóstico prévio de síndrome do intestino irritável. Todos os pacientes apresentaram remissão clínica completa durante o tratamento e não referiram efeitos colaterais da droga. Conclusão: As mulheres mais velhas que usam medicamentos de alto risco são sugestivas de CM. Evitar o atraso no diagnóstico de CM é fundamental para melhorar a qualidade de vida dos pacientes. A budesonida MMX foi eficaz, segura e bem tolerada.

MICROSCOPIC COLITIS: CONSIDERATIONS FOR GASTROENTEROLOGISTS, ENDOSCOPISTS, AND PATHOLOGISTS.

•Diagnosis of microscopic colitis necessitates effective communication among gastroenterologists, endoscopists, and pathologists. •The gastroenterologist should refer every patient with chronic watery diarrhea to perform a colonoscopy in spite of the benign course of the disease and the absence of alarm symptoms. •The endoscopist should take 2 or 3 biopsy samples of the colonic mucosa from the right and left colon, put in separate recipients, despite that the mucosa looked macroscopically normal. •The pathologist should be encouraged to use objective histological criteria to make the diagnosis. Microscopic colitis is a chronic inflammatory bowel disease characterized by non-bloody diarrhea that can range from mild to severe. It is difficult to attribute up to 10-20% of chronic diarrhea to microscopic colitis. The three determinants factors of the diagnosis are characteristic clinical symptoms, normal endoscopic picture of the colon, and pathognomonic histological picture. This manuscript aimed to update considerations and recommendations for professionals involved (gastroenterologist, endoscopists and pathologist) in the diagnosis of MC. In addition, a short recommendation about treatment.

THE MANAGEMENT OF DERMATITIS HERPETIFORMIS BY THE GASTROENTEROLOGIST. A SERIES OF CASES.

BACKGROUND: Dermatitis herpetiformis (DH) is considered a skin celiac disease (CD). The individuals can be seen by primary care professionals or by dermatologists that could refer the patient to a gastroenterologist. OBJECTIVE: The study aimed to investigate the clinical profile of patients diagnosed with DH and referred to a gastroenterologist and evaluate the treatment response. METHODS: We retrospectively studied patients with DH referred to the same gastroenterologist at a private office in Curitiba, Brazil, between January 2010 to December 2019. We included adult patients with a confirmed DH diagnosis. Symptoms, clinical signs, laboratory and histological data, as well as treatment response, were collected. RESULTS: Thirty-three patients were studied (60.6% women, mean age at diagnosis 40.8±12.61 years). The median delay for DH diagnosis was four years. Skin involvement was mild in 33.3%, moderate in 18.2%, and severe in 48.5%. The more frequent gastrointestinal complaints were abdominal distension (78.8%), flatulence (75.7%), and gastroesophageal reflux (51.5%). Depression and anxiety were observed in 81.8% and anemia in 51.1%. A higher prevalence of bone disorders was associated with higher age at DH diagnosis (P=0.035). Duodenal biopsy showed changes in all patients. Improvement after treatment only with a gluten-free diet (GFD) plus dapsone was verified in 81.2%. CONCLUSION: Patients with DH referred to a gastroenterologist showed a high frequency of gluten intolerance and systemic complaints. Duodenal histological alterations were found in all the cases. The treatment based on GFD plus dapsone was effective in most patients.

RESUMO CONTEXTO: A dermatite herpetiforme (DH) é considerada como a doença celíaca (DC) da pele. Os pacientes podem ser atendidos por profissionais do atendimento primário ou por dermatologistas que podem encaminhar o paciente a um gastroenterologista. OBJETIVO: Os objetivos do estudo foram investigar o perfil clínico dos pacientes com diagnóstico de DH encaminhados a um gastroenterologista e avaliar a resposta ao tratamento. MÉTODOS: Foram investigados retrospectivamente pacientes com DH encaminhados ao mesmo gastroenterologista em consultório particular em Curitiba, Brasil, entre janeiro de 2010 a dezembro de 2019. Foram incluídos pacientes adultos com diagnóstico confirmado de DH. Dados sobre sintomas e sinais clínicos, dados laboratoriais, histológicos e resposta ao tratamento foram coletados. RESULTADOS: Foram estudados 33 pacientes (60,6% mulheres, média de idade 40,8±12,61 anos). O atraso médio para o diagnóstico de DH foi de 4 anos. O envolvimento cutâneo foi considerado leve em 33,3%, moderado em 18,2% e grave em 48,5%. As queixas gastrointestinais mais frequentes foram distensão abdominal (78,8%), flatulência (75,7%) e refluxo gastroesofágico (51,5%). Depressão e ansiedade foram observadas em 81,8% e anemia em 51,1%. Maior prevalência de alterações ósseas foi associada à maior idade ao diagnóstico de DH (P=0,035). A biópsia duodenal mostrou alterações em todos os pacientes. A melhora após o tratamento apenas com dieta sem glúten e/ou dapsona foi verificada em 81,2%. CONCLUSÃO: Pacientes com DH encaminhados ao gastroenterologista apresentaram alta frequência de queixas gastrointestinais e sistêmicas. Alterações histológicas duodenais foram encontradas em todos os casos. O tratamento à base de dieta sem glúten e/ou dapsona foi eficaz na maioria dos pacientes.

ILEITIS - DO ENDOSCOPIST AND PATHOLOGIST SPEAK THE SAME LANGUAGE?

BACKGROUND: Ileitis is defined as an inflammation of the ileum, which is evaluated during colonoscopy. Biopsies should be performed on altered ileus, aiding to the diagnosis. OBJECTIVE: Evaluate the correlation of anatomopathological findings on ileitis between pathologists and endoscopists. METHODS: A retrospective, cross-sectional study, between 2013 and 2017. Examination report, indications for colonoscopy, and medical records were evaluated to identify whether the colonoscopic findings were clinically significant. Anatomopathological samples were reviewed by a pathologist expert in gastrointestinal tract. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age and those with previous intestinal resections were excluded. The correlation was assessed using the kappa coefficient index. RESULTS: A total of 5833 colonoscopies were conducted in the study period and 3880 cases were included. Ileal alterations were observed in 206 cases, with 2.94% being clinically significant. A hundred and sixty three biopsies were evaluated using the kappa index, resulting in agreement among pathologists of 0.067 and among pathologist and endoscopist of 0.141. CONCLUSION: It was observed that despite the low concordance between pathologists and endoscopists, there was no change in patient outcomes. This study confirms the importance of knowledge of the main anatomopathological changes related to ileitis by pathologists and endoscopists, making the best diagnosis and follow-up.

SERONEGATIVE CELIAC DISEASE IN BRAZILIAN PATIENTS: A SERIES OF CASES.

BACKGROUND: Celiac disease (CD) is an autoimmune disease characterized by immune reaction mostly to wheat gluten. The diagnosis is based on clinical, serological and histological findings in patients ingesting gluten. Cases that the clinical profile indicates CD and the autoantibodies are negative bring so a dilemma for the professional, as the risk of missed the diagnosis or a delay at the same. OBJECTIVE: To show the importance of correct diagnosis of cases with seronegative celiac disease (SNCD). METHODS: Ten cases of SNCD Brazilian patients were retrospectively studied (2013 to 2019). Data of clinical complaints, autoantibodies, IgA serum levels, histological findings and HLA-DQ2/DQ-8 were compiled. Dual-X densitometry, delay at diagnosis, previous autoimmune diseases and family history of CD were also checked. RESULTS: All SNCD patients presented clinical symptoms of CD, with confirmed diagnosis by histological findings of the duodenal mucosa and HLA-DQ2 and/or HLA-DQ8 positivity. All patients had normal IgA levels and negative autoantibodies (IgA-anti-transglutaminase and anti-endomysial). Dual-X densitometry detected osteopenia in two women and osteoporosis in two males, all with low levels of vitamin D. Delay diagnostic ranged from 1 to 19 years. Familiar occurrence of CD was reported in 40% of the cases. After one year of gluten-free diet, eight patients refer improve of symptoms, while duodenal biopsies, done in five cases, showed histological improvement. CONCLUSION: Patients who demonstrate the clinical profile of celiac disease with negative serology and normal levels of IgA, especially those who have family members with celiac disease, should be submitted to duodenal biopsies to look for histological findings.

RESUMO CONTEXTO: Ileíte é definida como uma inflamação ileal, que pode ser avaliada durante a colonoscopia. Biópsias devem ser realizadas em íleos alterados, acrescentando na definição diagnóstica. OBJETIVO: Avaliar a correlação de achados anatomopatológicos das ileítes entre patologistas e endoscopistas. MÉTODOS: Estudo retrospectivo, transversal, entre os anos de 2013 e 2017. Foram avaliados laudos de exames, indicações e prontuários para identificar quando os achados colonoscópicos foram significativos. As amostras de anatomopatologia foram revisadas por um patologista especialista em trato gastrointestinal. Foram incluídos pacientes acima de 18 anos, com ileoscopia, e excluídos pacientes menores de 18 anos e os com ressecções intestinais prévias. A correlação foi avaliada utilizando-se o coeficiente kappa. RESULTADOS: Durante o período do estudo foram realizadas 5833 colonoscopias, das quais 3880 foram incluídas. Alterações ileais foram observadas em 206 casos, com 2,94% sendo clinicamente significativo. Cento e sessenta e três biópsias foram avaliadas, resultando em coeficiente kappa entre patologistas de 0,067 e entre patologista e endoscopista de 0,141. CONCLUSÃO: Foi observado que a despeito da baixa concordância entre patologistas e endoscopistas, não houve mudança no desfecho clínico do paciente. Esse estudo confirma a importância do conhecimento dos achados anatomopatológicos principais das ileítes entre patologistas e endoscopias, fazendo o melhor diagnóstico e seguimento.

RESUMO CONTEXTO: A doença celíaca (DC) é uma doença autoimune caracterizada por reação imune principalmente ao glúten do trigo. O diagnóstico é baseado em achados clínicos, sorológicos e histológicos em pacientes que ingerem glúten. Casos em que o perfil clínico indica DC e os autoanticorpos são negativos trazem um dilema para o profissional, como o risco de não realizar ou atrasar o diagnóstico da DC. OBJETIVO: Mostrar a importância do diagnóstico correto de casos com doença celíaca soronegativa (DCSN). MÉTODOS: Dez casos de pacientes brasileiros com DCSN foram estudados retrospectivamente (2013 a 2019). Foram compilados dados de queixas clínicas, autoanticorpos, níveis séricos de IgA, achados histológicos e HLA-DQ2 / DQ-8. Densitometria, atraso no diagnóstico, doenças autoimunes prévias e histórico familiar de DC também foram verificados. RESULTADOS: Todos os pacientes com DCSN apresentaram sintomas clínicos de DC, com diagnóstico confirmado por achados histológicos da mucosa duodenal e positividade para HLA-DQ2 e/ou HLA-DQ8. Todos os pacientes apresentavam níveis normais de IgA e autoanticorpos negativos (IgA-anti-transglutaminase e anti-endomisial). A densitometria detectou osteopenia em duas mulheres e osteoporose em dois homens, todos com baixos níveis de vitamina D. O atraso no diagnóstico variou de 1 a 19 anos. A ocorrência familiar de DC foi relatada em 40% dos casos. Após 1 ano de dieta isenta em glúten, oito pacientes referem melhora dos sintomas, enquanto as biópsias duodenais, realizadas em cinco casos, mostraram melhora histológica. CONCLUSÃO: Pacientes que apresentam quadro clínico de doença celíaca com sorologia negativa e níveis normais de IgA, principalmente aqueles que possuem familiares com doença celíaca, devem ser submetidos à biópsia duodenal para pesquisa de achados histológicos.

REPRODUCTIVE ASPECTS IN BRAZILIAN CELIAC WOMEN.

BACKGROUND: Celiac disease (CD) is a chronic enteropathy in response to ingestion of gluten. CD was associated with gynecological disorders. OBJECTIVE: In this retrospective study, we aimed to investigate the age of menarche, age of menopause, number of pregnancies and abortions in Brazilian celiac patients. METHODS: We studied 214 women diagnosed with CD and as control group 286 women were investigated. RESULTS: Regarding the mean age of menarche, a significant difference was found (12.6±1.40 in CD and 12.8±1.22 years in healthy group; P=0.04). Regarding abortions, in CD women 38/214 (17.8%) and 28/286 (9.8%) in the control group reported abortion (P=0.0092, OR:1.98; CI95%=1.1- 3.3). There was no significant difference in the mean age of menopause nor number of pregnancies per woman. CONCLUSION: In this study, we found that celiac women had a higher mean age of menarche and higher risk of spontaneous abortions.

Gender-Related Differences in Celiac Patients at Diagnosis.

BACKGROUND: Clinical presentation of celiac disease (CD) in terms of gender have demonstrated differences between symptoms among women and men. This study evaluated the differences in the clinical presentation of CD among Brazilian men and women at the time of diagnosis. MATERIAL AND METHODS: We investigated data on symptoms and clinical signs of 240 patients (80 [33.3%] men and 160 [66.6%] women) aged >18 years who were diagnosed with CD during 2000-2017. The overall mean age at diagnosis was 38.3 ± 13.28 years, with the mean age being 38.1 ± 14.48 years for men and 38.4 ± 12.68 years for women (p = 0.16). Details regarding other previously diagnosed autoimmune diseases were enquired with the patient. All data were collected at the time of diagnosis of CD. RESULTS: Symptoms such as anxiety/depression (OR = 7.9), lack of appetite (OR = 3.5), flatulence (OR = 1.9), malaise (OR = 2.5), nausea (OR = 3.1), and vomiting (OR = 6.5) were more frequent in females than in males. Only steatorrhea was more frequent in men (OR = 2.6). Clinical signs such as anemia (OR = 2.8), short stature (OR >20), and weight loss (OR = 2.4) were also more frequent in women. Other findings such as diarrhea, abdominal distension or pain, and anorexia did not reveal differences in terms of gender. Regarding concomitant autoimmune diseases, dermatitis herpetiformis was more frequent in men (OR = 2.6), and thyroiditis was more frequent in women (OR = 10.5). CONCLUSION: Our study has demonstrated that men and women with CD presented differences in clinical presentation at the time of diagnosis. Women exhibited more gastrointestinal symptoms and clinical signs than men.

Comparison of the effects of endovenous laser ablation at 1470 nm versus 1940 nm and different energy densities.

OBJECTIVES: To evaluate histological and immunohistochemical changes in the great saphenous vein after endovenous laser ablation at two different wavelengths (1470 vs. 1940 nm) and linear endovenous energy density values (50 vs. 100 J/cm). METHOD: Segments were obtained from the conventional eversion removal of great saphenous vein and divided into a control group and four groups for ex vivo irradiation (control group; A: 1470 nm, 50 J/cm; B: 1470 nm, 100 J/cm; C: 1940 nm, 50 J/cm; D: 1940 nm, 100 J/cm). Fifty venous segments ( n = 10/group) were analyzed. Changes were classified into low-temperature changes, moderate-temperature changes, high-temperature changes, and very high-temperature changes. RESULTS: In the intima, low-temperature changes + moderate-temperature changes were significantly more prevalent in group A (65.4%) than in D ( p = 0.001). In the media, low-temperature changes + moderate-temperature changes were achieved mostly in groups A and C (77.4% and 75.0%, respectively). In adventitia fragments, 100% of changes in group A were low-temperature changes + moderate-temperature changes. CONCLUSIONS: The 1940-nm laser wavelength with linear endovenous energy density of 100 J/cm was excessively destructive to the intima and media causing a high rate of high-grade thermal damage. These findings corroborate the possibility of using lower linear endovenous energy densities with 1940-nm devices to achieve effective occlusion with less high grade thermal damage to the intima and media, as well as to prevent damages to the adventitia and perivenous tissues, including venous perforation and its attendant clinical consequences.

Doenças imunomediadas em pacientes com doença celíaca e em seus familiares: um estudo comparativo entre idade e sexo / Immune mediated diseases in patients with celiac disease and their relatives: a comparative study of age and sex

ABSTRACT BACKGROUND: Up to 15% of other immune-mediated diseases (IMDs) can occur in patients with CD throughout their lives and are associated with multiple factors, including sex and sex hormone levels. Moreover, sex is associated with differences in clinical presentation, onset, progression, and outcomes of disorders. OBJECTIVE: To investigate the prevalence of IMDs at diagnosis in patients with celiac disease (CD) and their first-degree relatives and to compare the findings between female and male patients of different age. METHODS: A retrospective study including Brazilian patients with CD who visited the same doctor during January 2012 to January 2017 was performed. Demographic and medical history data were collected through self-administered questionnaires and medical charts of the patients. In total, 213 patients were examined at diagnosis: 52 males (mean age, 40.0 years) and 161 females (mean age, 41.4 years). The patients were divided into two groups according to sex and age. RESULTS: IMDs were observed in 60.2% of the female (97/161) and 42.3% of the male patients (22/52; P=0.22). However, the frequency of IMDs was significantly higher in females aged 51-60 years than in males with same age (P=0.0002). Dermatitis herpetiformis (DH) was significantly more prevalent in males (P=0.02), whereas atopy was more prevalent in females (P=0.02). IMDs observed in first-degree relatives were similar to those observed in patients (70.9%; P<0.001), with a higher number observed in female relatives. CONCLUSION: The frequency of IMDs in CD patients was similar in all age groups and both sexes, except women diagnosed with CD after 51 years of age presented with an increased frequency of IMDs compared with males. Dermatitis herpetiformis was more prevalent in males, whereas atopy was more prevalent in females. No difference was observed in the type of IMDs between the first-degree relatives of both sexes.

RESUMO CONTEXTO: Até 15% das outras doenças imunomediadas (DIMs) podem ocorrer em pacientes com doença celíaca ao longo de suas vidas e estão associados a múltiplos fatores, incluindo sexo e níveis de hormônios sexuais. Além disso, o sexo está associado a diferenças na apresentação, início, progressão e desfecho das doenças. OBJETIVO: Investigar a prevalência de DIMs ao diagnóstico de doença celíaca e em seus familiares de primeiro grau e comparar os resultados entre sexo feminino e masculino em diferentes idades. MÉTODOS: Estudo retrospectivo incluindo pacientes brasileiros com diagnóstico de doença celíaca que realizaram acompanhamento com o mesmo médico no período de janeiro 2012 a janeiro de 2017. Dados demográficos e histórico médico foram coletados através de um questionário auto administrado e prontuários médicos dos pacientes envolvidos. No total, 213 pacientes eram portadores de doença celíaca, dos quais 52 do sexo masculino (idade média 40,0 anos) e 161 do sexo feminino (idade média 41,4 anos). Os pacientes foram divididos em dois grupos de acordo com o sexo e idade. RESULTADOS: DIMs foram observadas em 60,2% das pacientes femininas (97/161) e 42,4% dos pacientes masculinos (22/52; P=0,22). Entretanto, a frequência de DIMs foi significantemente maior em pacientes do sexo feminino com idade entre 51-60 anos que em pacientes masculinos da mesma idade (P=0,0002). Dermatite herpetiforme apresentou maior prevalência no sexo masculino (P=0,02), enquanto atopia obteve maior prevalência nas pacientes do sexo feminino (P=0,02). DIMs observadas em familiares de primeiro grau foram similares as encontradas nos pacientes (70,9%; P<0,001), com um maior número observado em familiares femininos. CONCLUSÃO: A frequência de DIMs em pacientes com doença celíaca foi similar nos grupos etários e ambos sexos, exceto as mulheres com diagnóstico de doença celíaca após a idade de 51 anos, as quais apresentaram um aumento na frequência de DIMs em comparação com os pacientes do sexo masculino. Dermatite herpetiforme apresentou maior prevalência em pacientes do sexo masculino, enquanto que atopia foi mais prevalente no sexo feminino. Em relação ao sexo, não foi observada diferença no tipo de DIMs observada entre os familiares de primeiro grau.

IMMUNE MEDIATED DISEASES IN PATIENTS WITH CELIAC DISEASE AND THEIR RELATIVES: A COMPARATIVE STUDY OF AGE AND SEX.

BACKGROUND: Up to 15% of other immune-mediated diseases (IMDs) can occur in patients with CD throughout their lives and are associated with multiple factors, including sex and sex hormone levels. Moreover, sex is associated with differences in clinical presentation, onset, progression, and outcomes of disorders. OBJECTIVE: To investigate the prevalence of IMDs at diagnosis in patients with celiac disease (CD) and their first-degree relatives and to compare the findings between female and male patients of different age. METHODS: A retrospective study including Brazilian patients with CD who visited the same doctor during January 2012 to January 2017 was performed. Demographic and medical history data were collected through self-administered questionnaires and medical charts of the patients. In total, 213 patients were examined at diagnosis: 52 males (mean age, 40.0 years) and 161 females (mean age, 41.4 years). The patients were divided into two groups according to sex and age. RESULTS: IMDs were observed in 60.2% of the female (97/161) and 42.3% of the male patients (22/52; P=0.22). However, the frequency of IMDs was significantly higher in females aged 51-60 years than in males with same age (P=0.0002). Dermatitis herpetiformis (DH) was significantly more prevalent in males (P=0.02), whereas atopy was more prevalent in females (P=0.02). IMDs observed in first-degree relatives were similar to those observed in patients (70.9%; P<0.001), with a higher number observed in female relatives. CONCLUSION: The frequency of IMDs in CD patients was similar in all age groups and both sexes, except women diagnosed with CD after 51 years of age presented with an increased frequency of IMDs compared with males. Dermatitis herpetiformis was more prevalent in males, whereas atopy was more prevalent in females. No difference was observed in the type of IMDs between the first-degree relatives of both sexes.
