Diagnostic challenge between Crohn's disease and intestinal tuberculosis in chronic diarrhea with ulcerated jejunal stenosis: a case report / Desafío diagnóstico entre la enfermedad de Crohn y la tuberculosis intestinal en la diarrea crónica con estenosis yeyunal ulcerada: reporte de un caso

ABSTRACT Intestinal tuberculosis and Crohn's disease are a diagnostic challenge because of the clinical, radiological and endoscopic similarity. The histological and microbiological findings are positive in less than 50%, which delays the correct treatment, putting the patient at risk. We reported a 34-year-old immunocompetent patient with 4 years of malabsorptive diarrhea, weight loss, nocturnal diaphoresis, abdominal pain and an ulcer with stenosis in the jejunum was found; she received empirical anti- tuberculosis treatment with clinical improvement. Later the culture was positive for M. tuberculosis.

RESUMEN La tuberculosis intestinal y la enfermedad de Crohn son un desafío diagnóstico debido a la similitud clínica, radiológica y endoscópica. Los hallazgos histológicos y microbiológicos son positivos en menos del 50%, lo que retrasa el correcto tratamiento, poniendo en riesgo al paciente. Reportamos un paciente de 34 años inmunocompetente con 4 años de diarrea malabsortiva, pérdida de peso, diaforesis nocturna, dolor abdominal y se encontró una úlcera con estenosis en yeyuno; recibió tratamiento empírico antituberculoso con mejoría clínica. Posteriormente el cultivo fue positivo para M. tuberculosis.

Perfil clínico, teste padrão da resistência à droga e resultados do tratamento de pacientes com tuberculose abdominal da Índia ocidental / Clinical profile, drug resistance pattern and treatment outcomes of abdominal tuberculosis patients in western india

ABSTRACT BACKGROUND: Abdominal tuberculosis is an increasing problem in developing world. OBJECTIVE: The objective of the study was to describe the clinical presentations, drug resistance pattern and treatment outcomes of abdominal tuberculosis in Western India. METHODS: All the cases of abdominal tuberculosis from May 2014 to April 2017, diagnosed on the basis of clinical profile and gross morphological findings at endoscopy, imaging, followed by histology and/or GeneXpert and MGIT culture were included. All patients received antitubercular drug (AKT) therapy according to national protocol. Patients were followed from diagnoses till completion of treatment and various parameters were studied. RESULTS: Out of the 176 patients, 48% were males. Abdominal pain was most common complaint in 83.5%. On colonoscopy terminal ileum and ileocaecal valve were most commonly involved segments. Upper gastrointestinal tract was involved in four patients. Overall ulceronodular lesions were most common followed by ulcerative/nodular lesion. Strictures in bowel were seen in 28 (15.9%) patients with ileocaecal valve being most commonly involved, of which 23 had symptomatic relief with AKT and only three required dilatation. Histopathology showed granuloma in 80.8% cases. MGIT was positive in 43 (35.80%) cases and GeneXpert was positive in 35 (26.1%) cases. Eight patients had multi drug resistant tuberculosis. Only two patients required surgical management. CONCLUSION: Abdominal tuberculosis with wide spectrum of presentation, can still be managed with early diagnosis and treatment even in patients with sub acute intestinal obstruction. Weight gain or resolving symptoms were considered early markers of treatment response. Patients with stricture can become asymptomatic with medical treatment alone.

RESUMO CONTEXTO: A tuberculose abdominal é um problema crescente no mundo em desenvolvimento. OBJETIVO: O objetivo do estudo foi descrever as apresentações clínicas, o padrão de resistência a fármacos e os desfechos de tratamento da tuberculose abdominal na Índia ocidental. MÉTODOS: Foram incluídos todos os casos de tuberculose abdominal de maio de 2014 a abril de 2017, diagnosticados com base no perfil clínico e nos resultados morfológicos brutos na endoscopia, imagem latente, seguido pela histologia e/ou pela cultura de GeneXpert e de MGIT. Todos os pacientes receberam a terapia antitubercular da droga (AKT) de acordo com o protocolo nacional. Os pacientes foram acompanhados de diagnósticos até a conclusão do tratamento e vários parâmetros foram estudados. RESULTADOS: Dos 176 pacientes, 48% eram do sexo masculino. A dor abdominal foi a queixa mais comum em 83,5%. Na colonoscopia, o íleo terminal e a válvula íleo-cecal foram os segmentos mais comumente envolvidos. O trato gastrointestinal superior foi envolvido em quatro pacientes. As lesões ulceronodulares totais foram as mais comuns seguidas pela lesão ulcerosa/nodular. As estenoses foram observadas em 28 (15,9%) pacientes priciplamente com a válvula íleo-cecal envolvida, dos quais 23 tiveram alívio sintomático com AKT e somente três necessitaram de dilatação. A histopatologia mostrou o granuloma em 80,8% casos. O MGIT foi positivo em 43 (35,80%) e GeneXpert foi positivo em 35 (26,1%) casos. Oito pacientes tiveram tuberculose resistente a múltiplas drogas. Apenas dois pacientes necessitaram de manejo cirúrgico. CONCLUSÃO: A tuberculose abdominal com amplo espectro de apresentação, ainda pode ser manuseada com diagnóstico precoce e tratamento mesmo em pacientes com obstrução intestinal sub-aguda. Ganho de peso ou sintomas resolvidos foram considerados marcadores precoces de resposta ao tratamento. Pacientes com estenose podem se tornar assintomáticos com tratamento médico isoladamente.

Tuberculosis ileocecal: revisión de la literatura a partir de un caso clínico / Ileocecal tuberculosis: literature review from a case report

Tuberculosis (TB) remains a major public health challenge. The true incidence of intestinal TB is unknown, as it can be asymptomatic, and by its nature, often diverts its diagnosis to neoplastic diseases or inflammatory bowel disease. Therefore, we must have a high index of suspicion, not only in high risk populations and immunocompromised patients. Diagnostic tests that certify the pathology, don't always achieve excellent performance. Endoscopic findings are not always clear in differentiating malignancy, and in some cases, a therapeutic trial may be needed to confirm the disease. We present the case of a patient with chronic diarrhea, consumptive syndrome and without respiratory symptoms at its onset.

La tuberculosis (TBC) sigue siendo un reto importante de salud pública. La verdadera incidencia de TBC intestinal es desconocida, ya que puede ser asintomática, y por su naturaleza a menudo desvía su diagnóstico a patologías neoplásicas o de enfermedad inflamatoria intestinal. Por lo tanto, se debe tener un alto índice de sospecha, no sólo en poblaciones de alto riesgo y en pacientes inmunocomprometidos. Las pruebas diagnósticas que certifiquen la patología no siempre se logran ni tienen un excelente rendimiento. Los hallazgos endoscópicos no siempre son claros para diferenciarla de una neoplasia, y en algunos casos una prueba terapéutica puede ser la confirmación de la enfermedad. Presentamos el caso de un paciente con diarrea crónica, cuadro consuntivo y sin síntomas respiratorios al inicio de su cuadro.

Tuberculosis intestinal: aspectos clinicos, diagnosticos y terapeuticos / Intestinal tuberculosis: clinical, diagnostic and therapeutical aspects

Presentamos el estudio de 351 pacientes de TBC intestinal observados en el Hospital Regional Honorio Delgado de Arequipa-Peru, entre 1960 y 1983. Se analizan los problemas etiopatogenicos, clinicos, diagnosticos y terapeuticos, llegandose a la conclusion que, en nuestro medio la TBC intestinal sigue constituyendo un importante problema medico-social, que debe ser encarado adecuadamente por nuestras autoridades de salud
