Immunohistochemistry and real-time Polymerase Chain Reaction: importance in the diagnosis of intestinal tuberculosis in a Peruvian population.

INTRODUCTION: The diagnosis of intestinal tuberculosis is challenging even nowadays. This study aims to report the positivity rates of new diagnostic methods such as immunohistochemistry and Real-Time Polymerase Chain Reaction in patients with intestinal tuberculosis, as well as describe the pathological and endoscopic features of intestinal tuberculosis in our population. METHODS: This was a retrospective observational study conducted in patients diagnosed with intestinal tuberculosis, between 2010 to 2023 from the Hospital Nacional Daniel Alcides Carrion and a Private Pathology Center, both located in Peru. Clinical data was obtained, histologic features were independently re-evaluated by three pathologists; and immunohistochemistry and real-time Polymerase Chain Reaction evaluation were performed. The 33 patients with intestinal tuberculosis who fulfilled the inclusion criteria were recruited. RESULTS: Immunohistochemistry was positive in 90.9% of cases, while real-time Polymerase Chain Reaction was positive in 38.7%. The ileocecal region was the most affected area (33.3%), and the most frequent endoscopic appearance was an ulcer (63.6%). Most of the granulomas were composed solely of epithelioid histiocytes (75.8%). Crypt architectural disarray was the second most frequent histologic finding (78.8%) after granulomas, but most of them were mild. CONCLUSION: Since immunohistochemistry does not require an intact cell wall, it demonstrates higher sensitivity compared to Ziehl-Neelsen staining. Therefore, it could be helpful for the diagnosis of paucibacillary tuberculosis.

Febre tifoide como causa de abdome agudo: um diagnóstico diferencial a ser lembrado / Typhoid fever as a cause of acute abdomen: a differential diagnosis to remember

A infecção causada pela bactéria Salmonella typhi continua sendo importante preocupação para a saúde global, especialmente em regiões de acesso limitado a saneamento básico. Conhecida por sua ampla variedade de apresentações clínicas e agressividade ao provocar necrose tecidual, a febre tifoide pode representar um diagnóstico desafiador em áreas endêmicas onde outras doenças com manifestações semelhantes têm maior prevalência, o que agrava ainda mais seu potencial de morbimortalidade. Neste artigo relatamos o caso de um paciente com febre tifóide cujo diagnóstico foi inicialmente confundido com tuberculose intestinal e que evoluiu para perfuração e óbito.

Treatment of intestinal tuberculosis with small bowel perforation: a case report.

BACKGROUND: Diagnosis of intestinal tuberculosis poses a dilemma to physicians due to nonspecific symptoms like abdominal pain, fever, nausea, and a change in bowel habit. In particular, the distinction between inflammatory bowel disease and intestinal tuberculosis remains challenging. CASE PRESENTATION: A 27-year-old man from Colombia presented with fever, night sweats, and progressive lower abdominal pain. Computed tomography revealed a thickening of the bowel wall with a mesenterial lymphadenopathy, ascites ,and a pleural tumor mass. Histology of intestinal and pleural biopsy specimens showed a granulomatous inflammation. Although microscopy and polymerase chain reaction (PCR) for Mycobacterium tuberculosis (MTB) were negative, empirical MTB treatment was initiated on suspicion. Due to a massive post-stenotic atrophied intestinal bowel, MTB medications were administered parenterally in the initial phase of treatment to guarantee adequate systemic resorption. The complicated and critical further course included an intra-abdominal abscess and bowel perforation requiring a split stoma, before the patient could be discharged in good condition after 3 months of in-hospital care. CONCLUSIONS: This case highlights the clinical complexity and diagnostic challenges of intestinal MTB infection. A multidisciplinary team of physicians should be sensitized to a timely diagnosis of this disease, which often mimics inflammation similar to inflammatory bowel disease, other infections, or malignancies. In our case, radiological findings, histological results, and migratory background underpinned the suspected diagnosis and allowed early initiation of tuberculostatic treatment.

Tuberculosis infantil sistémica / Systemic childhood tuberculosis

Introducción: La tuberculosis infantil, definida como la enfermedad infectocontagiosa producida por el bacilo de Koch en pacientes menores de 15 años, continúa siendo un problema de salud pública debido a la cantidad de casos que anualmente se informan, además de ser un desafío para el pediatra en el diagnóstico y tratamiento de esta enfermedad. Objetivo: Describir el caso de un paciente varón con un cuadro de tuberculosis multisistémica. Presentación de caso: Paciente varón de 13 años con un cuadro progresivo de pérdida de peso de 20 kilos en 3 meses, dolor abdominal de localización difusa, tos seca e hiporexia. En los exámenes realizados, se encontraron lesiones cavitarias pulmonares, múltiples adenopatías enteroperitoneales y baciloscopia positiva en heces y orina; con lo que se llegó al diagnóstico de tuberculosis sistémica infantil y se inició esquema antituberculoso. El paciente evolucionó favorablemente y se encuentra estable. Conclusiones: Ante un paciente pediátrico con síndrome consuntivo, procedente de una zona endémica, la tuberculosis debe ser una de las primeras opciones en el diagnóstico diferencial(AU)

Introduction: Childhood tuberculosis, defined as the infectious-contagious disease caused by the Koch bacillus in patients under 15 years of age, continues to be a public health problem due to the number of cases that are reported annually; in addition to represent a challenge for the pediatrician in the diagnosis and treatment of this disease. Objective: Describe the case of a male patient with a picture of multisystem tuberculosis. Case presentation: A 13-year-old male patient with a progressive weight loss of 20 kg in 3 months, abdominal pain of diffuse location, dry cough and hyporexia. In the examinations carried out, pulmonary cavitary lesions, multiple enteroperitoneal adenopathies and positive smears in feces and urine were found; with which the diagnosis of systemic tuberculosis in children was reached and an antituberculous scheme was initiated. The patient progressed favorably and he is stable. Conclusions: In the case of a pediatric patient with a wasting syndrome, and coming from an endemic area, tuberculosis should be one of the first options in the differential diagnosis(AU)

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.

Consideraciones diagnósticas y terapéuticas de la tuberculosis intestinal / Diagnostic and Therapeutic Considerations about Abdominal Tuberculosis

Introducción: La tuberculosis es una enfermedad reemergente, importante como causa mayor de incapacidad y muerte en muchas zonas del mundo. La tuberculosis intestinal representa 11 por ciento de todas las formas extrapulmonares; 0,5 por ciento de todos los casos nuevos de y el 10 al 15 por ciento en los no infectados por el VIH. En el municipio Tunas se notificó el caso de un adolescente de 17 años, masculino, al que se le diagnostica esta enfermedad luego de haber presentado síntomas de dolor abdominal recurrente durante de varios meses antes del diagnóstico. Objetivo: Actualizar la información sobre el diagnóstico y tratamiento de la tuberculosis intestinal. Métodos: Se realizó una revisión bibliográfica sobre tuberculosis intestinal con la literatura encontrada en bases de datos disponibles en la red Infomed: PubMed, Hinari, The Cochrane Library, SciELO, MEDLINE y MedicLatina; con un enfoque histórico-lógico y de análisis-síntesis. Conclusiones: El diagnóstico precoz de la tuberculosis intestinal sin tuberculosis pulmonar activa continúa siendo un problema de salud, ya que los parámetros clínicos, bioquímicos, imagenológicos y endoscópicos aún carecen de especificidad, y en algunos casos se ha mostrado resistencia al tratamiento habitual(AU)

Introduction: Tuberculosis is a reemerging disease, also important as a major cause of disability and death in many regions of the world. Abdominal tuberculosis represents 11 percent of all extrapulmonary forms; 0.5 percent of all new cases of HIV infection and 10-15 percent of those not infected with HIV. In Las Tunas Municipality, the case of a 17-year-old male adolescent who was diagnosed with this disease was reported after the patient presented symptoms of recurrent abdominal pain for several months before diagnosis. Objective: To update information on the diagnosis and treatment of abdominal tuberculosis. Methods: A literature review on intestinal tuberculosis was carried out with the literature found in databases available on the Infomed network, such as PubMed, Hinari, The Cochrane Library, SciELO, MEDLINE, and MedicLatina, with a historical-logical and analysis-synthesis approach. Conclusions: The early diagnosis of intestinal tuberculosis without active pulmonary tuberculosis continues to be a health concern, since clinical, biochemical, imaging, and endoscopic parameters still lack specificity, and, in some cases, resistance to usual treatment has been shown(AU)

[Duodenal obstruction and upper gastrointestinal bleeding as the initial presentation of an isolated duodenal tuberculosis]. / Obstrucción duodenal y hemorragia digestiva alta como presentación inicial de una tuberculosis duodenal aislada.

Primary duodenal tuberculosis is rare, even in endemic regions. The diagnosis poses a major challenge and requires a high index of suspicion, supported by imaging studies, microbiology, and histopatology obtained by endoscopic or surgical biopsy. We report the case of a 31-year-old man, without HIV infection or any previous history of tuberculosis, who presented with duodenal obstruction. After exploratory laparotomy, he presented a duodenal stenosis and upper gastrointestinal bleeding. A total of four diagnostic procedures (one laparotomy and three endoscopies) were performed, all of which included biopsies. Only the last endoscopy made with the technique "biopsy upon biopsy" showed the presence of acid fast bacilli and granulomas. The diagnosis of tuberculosis was confirmed by polymerase chain reaction in duodenal tissue. There was no evidence of involvement of other organs by tuberculosis. The patient had an excellent therapeutic response.

CLINICAL PROFILE, DRUG RESISTANCE PATTERN AND TREATMENT OUTCOMES OF ABDOMINAL TUBERCULOSIS PATIENTS IN WESTERN INDIA.

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.

Obstrucción duodenal y hemorragia digestiva alta como presentación inicial de una tuberculosis duodenal aislada / Duodenal obstruction and upper gastrointestinal bleeding as the initial presentation of an isolated duodenal tuberculosis

Resumen La tuberculosis duodenal primaria es muy infrecuente, incluso en regiones endémicas. El diagnóstico plantea un gran reto, y requiere un alto índice de sospecha, apoyado en estudios de imágenes, microbiología, e histopatología obtenida por biopsia endoscópica o quirúrgica. Presentamos el caso de un varón de 31 años, sin infección por VIH ni antecedente de tuberculosis, que debutó con una obstrucción duodenal. Posterior a una laparatomía exploradora presentó una estenosis duodenal y una hemorragia digestiva alta. Luego de varias biopsias no concluyentes, sólo la última, realizada con la técnica "biopsia sobre biopsia", demostró la presencia de granulomas con bacilos ácido-alcohol resistentes. El diagnóstico de tuberculosis fue confirmado por reacción de polimerasa en cadena de tejido duodenal. No se evidenció compromiso de otros órganos. La respuesta terapéutica fue excelente.

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 abdominal: patología infrecuente en un paciente joven: reporte de un caso / Abdominal tuberculosis: an unusual disease in a young patient: a case report

Resumen Introducción: La tuberculosis abdominal es un problema reemergente, y es una de las enfermedades transmisibles más importante en todo el mundo. A pesar de las expectativas acerca de su erradicación en países en desarrollo, ha sido recientemente declarada de nuevo como una patología de emergencia mundial. Con el aumento de su incidencia y prevalencia, su forma abdominal es una de las presentaciones de afectación extrapulmonar más comunes. Objetivo: Dado que la tuberculosis puede afectar diversos órganos, tiene una amplia gama y gran espectro de signos y síntomas que dificultan su diagnóstico y retrasan el tratamiento. Por esto, se realiza esta revisión de tema, concentrándonos en que el alto índice de sospecha debe ser un factor importante en el diagnóstico precoz, para que una vez establecido, se pueda iniciar el tratamiento ayudando a prevenir y disminuir las altas tasas de morbilidad y mortalidad evidenciadas en la actualidad. Caso Clínico: Paciente joven con presencia de ascitis secundaria a tuberculosis abdominal confirmada por una biopsia y el aumento de la adenosin deaminasa en el líquido peritoneal. Se describen los principales hallazgos clínicos, paraclínicos, estudios imagenológicos y tratamiento.

Introduction: Abdominal tuberculosis is a reemerging problem and is one of the most important communicable diseases in the world. Despite expectations about the eradication in developing countries, it has recently been re-declared as a global emergency pathology. The increased incidence and prevalence shows an abdominal shape as one of the most common extrapulmonary involvement presentations. Objective: Since tuberculosis can affect various organs, it has a wide range and spectrum of signs and symptoms that make diagnosis difficult and delay treatment. Therefore, this review of the topic is done, concentrating on the fact that the high suspicion index should be an important factor in the early diagnosis. Treatment can be initiated helping to prevent and reduce high morbidity and mortality rates. Case Report: We present a case of a young patient with ascites secondary to abdominal tuberculosis confirmed by biopsy and increased adenosine deaminase in the peritoneal fluid. The main clinical findings, paraclinic, imaging studies and treatment are described.
