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.

Prevalence of eating disorders in patients with celiac disease: a comparative study with healthy individuals.

INTRODUCTION: Celiac disease is a chronic immune-mediated disease, which is triggered and maintained by gluten in genetically susceptible individuals. Eating disorders are a persistent disturbance in eating-related behavior that results in altered food consumption or absorption and that significantly impairs physical health or psychosocial functioning. OBJECTIVE: This study aimed at evaluating the prevalence of eating disorders in Brazilian celiac patients. METHODS: This cross-sectional study was conducted as online survey including adult celiac patients who agreed to participate and a paired control health group. Questionnaires included questions about socioeconomic data and celiac disease diagnosis, and a validated questionnaire about eating disorders (Eating Attitudes Test-26. RESULTS: In total, 741 responses were studied, with 484 from the celiac group and 257 from the control group. No significant difference was observed between the number of individuals at risk of developing eating disorder (p=0.39). Both groups showed a high risk of developing eating disorders (34.2% in the celiac group and 37.7% in the control group). Furthermore, among patients with celiac disease, we found higher scores on the Eating Attitudes Test-26 in those with depression (p=0.0013), those with living difficulty due to the disease (p<0.0001), and those dissatisfied with their weight (p<0.0001). CONCLUSION: In the sample analyzed, no greater risk of eating disorders was identified in patients with celiac disease compared with the control group. However, in general, about one-third of the respondents in each group had scores associated with the risk of eating disorders. Among celiac patients, depression, difficulties living with celiac disease, and being unhappy with one's weight were associated with higher risk for eating disorder.

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.

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.

Alert for bone alterations and low serum concentrations of vitamin D in patients with intestinal inflammatory disease.

BACKGROUND: Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are characterized by chronic inflammation of the intestine that can reduce the absorption of nutrients such as vitamin D and calcium. OBJECTIVE: To investigate bone alterations and serum levels of vitamin D in patients with IBD. METHOD: This was a cross-sectional study based on a review of medical records of patients from a private office in Curitiba, PR, Brazil. Serum levels of vitamin D and bone densitometry were measured at diagnosis of IBD. A total of 105 patients were included; 38 (58.4%) with CD; 27 (41.6%) with UC and 40 with irritable bowel syndrome (IBS) as comparison group. RESULTS: When compared to patients with UC, CD patients showed a higher prevalence of bone alterations, being 15.8% with osteoporosis and 36.8% with osteopenia. In UC, bone alterations occurred in 29.6% of cases, 3.7% with osteoporosis and 25.9% with osteopenia. As for vitamin D levels, among CD patients, 10.5% had vitamin deficiency, 65.8% insufficiency and 23.7% were sufficient. In UC, 7.4% of cases had deficiency, 74.1% insufficiency and 18.5% had sufficient serum levels of vitamin D. In the group with IBS, deficiency was observed in 17.5% of cases, insufficiency in 55% and sufficiency in 27.5% of them. There was no significant difference between groups. CONCLUSION: IBD patients have a high prevalence of bone changes, especially those with CD. Serum levels of vitamin D are below the recommended in all the evaluated groups.

Tratamento da doença celíaca: estado da arte / Celiac disease treatment; state of the art

A falta de opções terapêuticas para a Doença Celíaca (DC) tornou-se um problema de grande relevância no setor farmacêutico em decorrência do aperfeiçoamento das técnicas sorológicas de diagnóstico e, consequentemente, do aumento do número de indivíduos com diagnóstico confirmado para esta doença. Até o momento, a única terapia eficaz na DC é a dieta isenta de glúten, um tratamento aparentemente simples, mas que tem enormes reflexos nos hábitos nutricionais e sociais do paciente. O conhecimento do complexo mecanismo patogênico da DC permitiu o gradual desenvolvimento de pesquisas em busca de novas opções terapêuticas, entre as quais podemos destacar a ingestão oral de enzimas capazes de hidrolisar o glúten, inibidores da enzima transglutaminase tecidual, inibidores da permeabilidade intestinal, e indutores da tolerância oral ao glúten. Este estudo, além de descrever algumas características da Doença Celíaca e sua relação com a estrutura do glúten, compila informações de diversos autores sobre o desenvolvimento de novos tratamentos para a doença, com objetivo de identificar as opções terapêuticas que apresentam os maiores avanços e, portanto, tem potencial para estarem à disposição dos pacientes celíacos em um futuro próximo.

The lack of therapeutic options for celiac disease (CD) has become a relevant issue in the pharmaceutical sector, as a result of the improvement on technical diagnostic serological and the following increase in the number of individuals with confirmed diagnosis for this disease. To date, the only effective therapy to CD is the gluten-free diet, a seemingly simple treatment, but that has enormous repercussions in the social and nutritional habits of the patient. New findings on the complex pathogenic mechanism of CD allowed gradually the development of researches to look for new therapeutic options, among which we can highlight the oral intake of enzymes capable to hydrolyze the gluten, inhibitors of tissue transglutaminase enzyme, inhibitors of intestinal permeability, and tolerance induction of gluten. This study, besides to describing some features of celiac disease and its relationship with the structure of gluten, compiles information from several authors regarding the development of new treatment of this disease, with the goal of identifying therapeutic options that present the biggest advances and, therefore, has the potential to be at the disposal of celiac patients in a near future.

LOW BONE MINERAL DENSITY IN BRAZILIAN PATIENTS AT DIAGNOSIS OF CELIAC DISEASE.

BACKGROUND: Low bone mineral density is considered an extra-intestinal manifestation of celiac disease with reduced bone mass, increased bone fragility, and risk of fractures. Celiac disease is considered a condition at high risk for secondary osteoporosis and the evaluation of bone density is very important in the clinical management of these patients. OBJECTIVE: The present study aimed to investigate bone alterations in celiac patients from Curitiba, South Region of Brazil at diagnosis, correlating the findings with age and gender. METHODS: Patients who were included in the study were attended to in a private office of the same physician from January 2009 to December 2013. The diagnosis of celiac disease was done through clinical, serological and histological findings. All data were collected from the medical charts of the patients. After the diagnosis of celiac disease, evaluation for low bone mineral density was requested by dual-energy X-ray absorptiometry (DEXA). DEXA bone densitometer was used to estimate low bone mineral density at the lumbar spine and femur. RESULTS: A total of 101 patients, 82 (81.2%) female and 19 (18.8%) male subjects, with mean age of 39.0±3.03 years were included. At celiac disease diagnosis, 36 (35.6%) were younger than 30 years, 41 (40.6%) were between 31 and 50 years, and 24 (23.8%) were older than 50 years. Among the evaluated patients, 69 (68.3%) presented low bone mineral density, being 47% with osteopenia and 32% with osteoporosis. Patients who were older than 51 years and diagnosed with celiac disease presented low bone mineral density in 83.3% (20/24) of the cases. As expected, age influenced significantly the low bone mineral density findings. Among women, low bone mineral density was present with high frequency (60%) from 30 to 50 years. In patients diagnosed older than 60 years (n=8), all the women (n=5) and two of the three men had osteoporosis. CONCLUSION: This study demonstrated that 69% of Brazilian patients with celiac disease at diagnosis had low bone mineral density, being more frequent in women older than 50 years.

LOW BONE MINERAL DENSITY IN BRAZILIAN PATIENTS AT DIAGNOSIS OF CELIAC DISEASE / Alterações ósseas em celíacos brasileiros ao diagnóstico

BackgroundLow bone mineral density is considered an extra-intestinal manifestation of celiac disease with reduced bone mass, increased bone fragility, and risk of fractures. Celiac disease is considered a condition at high risk for secondary osteoporosis and the evaluation of bone density is very important in the clinical management of these patients.ObjectiveThe present study aimed to investigate bone alterations in celiac patients from Curitiba, South Region of Brazil at diagnosis, correlating the findings with age and gender.MethodsPatients who were included in the study were attended to in a private office of the same physician from January 2009 to December 2013. The diagnosis of celiac disease was done through clinical, serological and histological findings. All data were collected from the medical charts of the patients. After the diagnosis of celiac disease, evaluation for low bone mineral density was requested by dual-energy X-ray absorptiometry (DEXA). DEXA bone densitometer was used to estimate low bone mineral density at the lumbar spine and femur.ResultsA total of 101 patients, 82 (81.2%) female and 19 (18.8%) male subjects, with mean age of 39.0±3.03 years were included.

ContextoBaixa densidade mineral óssea é considerada uma manifestação extra-intestinal da doença celíaca com redução da massa óssea, aumento da fragilidade óssea e risco de fraturas. A doença celíaca é considerada uma condição de alto risco para a osteoporose secundária e a avaliação da densidade óssea é muito importante no manejo clínico dos pacientes.ObjetivoO presente estudo teve como objetivo investigar as alterações ósseas presentes em pacientes com doença celíaca de Curitiba-PR, no momento do diagnóstico, correlacionando os achados com a idade e gênero.MétodosOs pacientes incluídos no estudo foram atendidos por um só médico no período de janeiro/2009 a dezembro/2013. O diagnóstico da doença celíaca foi feito através das manifestações clínicas, sorologia específica e achados histológicos da mucosa duodenal. Todos os dados foram coletados a partir dos prontuários dos pacientes. Após o diagnóstico da doença celíaca, foi solicitada a avaliação de densidade mineral óssea por meio de densitometria (dual-energy X-ray absorptiometry DEXA). DEXA foi utilizada para estimar a densidade mineral óssea na coluna lombar e fêmur.ResultadosUm total de 101 pacientes, 82 (81,2%) mulheres e 19 (18,8%) homens, com idade média de 39,0±3,03 anos foram incluídos. No momento do diagnóstico de doença celíaca, 36 (35,6%) tinham menos de 30 anos, 41 (40,6%) tinham entre 31 e 50 anos, e 24 (23,8%) tinham mais de 50 anos. Entre os pacientes avaliados, 69 (68,3%) apresentaram baixa densidade mineral óssea, 47% deles com osteopenia e 32% com a osteoporose. Os pacientes maiores de 51 anos de idade apresentaram baixa densidade mineral óssea em 83,3% (20/24) dos casos. Como esperado, a idade influenciou significativamente os resultados da baixa densidade mineral óssea. Entre as mulheres, baixa densidade mineral óssea foi observada com alta frequência (60%) também na faixa etária entre 30 a 50 anos. Pacientes diagnosticados mais de 60 anos (n=8), todas as mulheres (n=5) e dois dos três homens tinham osteoporose.ConclusãoO presente estudo demonstrou que 69% dos pacientes brasileiros com doença celíaca no momento do diagnóstico apresentaram baixa densidade mineral óssea, sendo mais frequente em mulheres com mais de 50 anos.

FECAL CALPROTECTIN: levels for the ethiological diagnosis in Brazilian patients with gastrointestinal symptoms.

BACKGROUND: Determination of fecal calprotectin can provide an important guidance for the physician, also in primary care, in the differential diagnosis of gastrointestinal disorders, meanly between inflammatory bowel diseases and irritable bowel syndrome. Objectives The aims of the present study were to prospectively investigate, in Brazilian adults with gastrointestinal complaints, the value of fecal calprotectin as a biomarker for the differential diagnosis between functional and organic disorders and to correlate the concentrations with the activity of inflammatory bowel diseases. METHODS: The study included consecutive patients who had gastrointestinal complaints in which the measurement levels of fecal calprotectin were recommended. Fecal calprotectin was measured using a Bühlmann (Basel, Switzerland) ELISA kit. RESULTS: A total of 279 patients were included in the study, with median age of 39 years (range, 18 to 78 years). After clinical and laboratorial evaluation and considering the final diagnosis, patients were allocated into the following groups: a) Irritable Bowel Syndrome: 154 patients (102 female and 52 male subjects). b) Inflammatory Bowel Diseases group: 112 patients; 73 with Crohn's disease; 38 female and 35 male patients; 52.1% (38/73) presented active disease, and 47.9% (35/73) had disease in remission and 39 patients with ulcerative colitis;19 female and 20 male patients; 48.7% (19/39) classified with active disease and 49.3% (20/39) with disease in remission. A significant difference (P<0.001) was observed between the median value of fecal calprotectin in Irritable Bowel Syndrome group that was 50.5 µg/g (IQR=16 - 294 µg/g); 405 µg/g (IQR=29 - 1980 µg/g) in Crohn's disease patients and 457 µg/g (IQR=25 - 1430 µg/g) in ulcerative colitis patients. No difference was observed between the values found in the patients with Crohn's disease and ulcerative colitis. Levels of fecal calprotectin were significantly lower in patients with inflammatory bowel diseases in remission when compared with active disease (P<0.001). CONCLUSIONS: The present study showed that the determination of fecal calprotectin assists to differentiate between active and inactive inflammatory bowel diseases and between inflammatory bowel diseases and irritable bowel syndrome.
