Megacolon tóxico en paciente con COVID-19 / Toxic megacolon in a patient with Covid-19

Introducción: La pandemia derivada de la enfermedad por el nuevo coronavirus 2019 (COVID-19) se ha convertido en una emergencia de salud pública mundial, debido a que puede desarrollar complicaciones que amenazan la vida. Si bien se sabe que el SARS-CoV-2 causa enfermedad pulmonar sustancial, se han observado muchas manifestaciones extrapulmonares, incluyendo el compromiso del sistema gastrointestinal. El megacolon tóxico es una complicación rara pero, potencialmente, mortal que se asocia más con la enfermedad inflamatoria intestinal. Sin embargo, cualquier afección que conduzca a la inflamación del colon puede conducir a una dilatación tóxica. Objetivo: Se presenta el caso de un paciente con un síndrome de dificultad respiratoria aguda secundario a una infección por SARS-COV-2. De manera concomitante presentó un cuadro de dilatación no obstructiva del colon, asociado con toxicidad sistémica. Caso clínico: El desarrollo de megacolon tóxico en un paciente con SARS-COV-2 puede estar justificado debido a que el virus infecta las células huésped a través del receptor de la enzima convertidora de angiotensina 2. Se cumplieron los criterios diagnósticos para megacolon tóxico. Conclusiones: Esta también se encuentra altamente expresada en las células epiteliales intestinales, por lo tanto, se debe considerar su diagnóstico oportuno para una intervención temprana, en aras de reducir la tasa de mortalidad tanto como sea posible(AU)

Introduction: The pandemic derived from the 2019 novel coronavirus disease (COVID-19) has become a global public health emergency, due to the fact that it can develop life-threatening complications. Although SARS-CoV-2 is known to cause substantial lung disease, many extra-pulmonary manifestations have been observed, including involvement of the gastrointestinal system. Toxic mega colon is a rare but life-threatening complication most associated with inflammatory bowel disease. However, any condition that leads to inflammation of the colon can lead to toxic dilation. Objective: To report the case of a patient with ARDS secondary to a SARS-COV-2 infection. Concomitantly, she had non-obstructive dilation of the colon, associated with systemic toxicity. Clinical case report: The development of toxic mega colon in a patient with SARS-COV-2 may be justified because the virus infects host cells through the angiotensin-converting enzyme 2 receptor. The diagnostic criteria for toxic megacolon were met. Conclusions: It is also highly expressed in intestinal epithelial cells, therefore, its timely diagnosis should be considered for early intervention, in order to reduce the mortality rate as much as possible(AU)

Megacolon tóxico de origen idiopático: reporte de caso / Megacolon toxic of idiophatic origin: case report

Resumen El megacolon tóxico (MT) es una patología con una tasa de mortalidad superior al 80% desencadenada por un proceso inflamatorio progresivo que compromete la pared del colon con dilatación secundaria de la luz intestinal debido a procesos inflamatorios o infecciosos. Su presentación clínica es infrecuente y los pilares básicos en su manejo son un diagnóstico oportuno, un manejo médico adecuado (antibiótico, reanimación hídrica y corrección metabólica) y, de ser necesario, un manejo quirúrgico eficaz que evite al máximo las complicaciones que empeoran el pronóstico de los pacientes. En este artículo se presenta un caso de una paciente con choque séptico secundario a MT, con desenlace fatal y con sospecha de un cuadro de colangitis grado III descartado por ecografía, lo cual generó distorsiones en su enfoque y manejo inicial. Por deterioro clínico y distensión abdominal, la paciente se llevó a laparoscopia diagnóstica en la que se evidenció un compromiso isquémico severo de todo el colon sin compromiso de intestino delgado, razón por la que se le realizó una colectomía total. El reporte de patología y la historia clínica descartan colitis ulcerativa o enfermedad de Crohn, lo que confirmó el MT. La paciente no presentaba factores de riesgo para el desarrollo de colitis pseudomembranosa. Se concluyó que fue la presentación de un caso de MT idiopático.

Abstract Toxic megacolon is a pathology whose mortality rate is over 80%. A progressive inflammatory process compromises the colon wall, and secondary dilation of the intestinal lumen occurs due to inflammatory or infectious processes. Its clinical presentation is bizarre. but the basic pillars for management are opportune diagnosis and adequate medical management with antibiotics, water resuscitation, and metabolic correction. If necessary, effective surgical management can prevent the development of complications that worsen the disease and the prognosis of a patient. In this article we present the case of a patient who died after developing septic shock secondary to toxic megacolon. Cholangitis grade III was suspected, but discarded after ultrasonography, and this resulted in generated distortions in approach and initial management. Due to clinical deterioration and abdominal distension, the patient underwent diagnostic laparoscopy which revealed severe ischemic compromise of the entire colon but without involvement of the small intestine. For this reason, a total colectomy was performed. The pathology report and clinical history ruled out ulcerative colitis or Crohn's disease which confirmed the diagnosis of toxic megacolon. The patient had no risk factors for the development of pseudomembranous colitis. We conclude that this was a case of idiopathic toxic megacolon.

Management of acute severe ulcerative colitis: a clinical update / Manejo da colite ulcerativa aguda grave: atualização terapêutica

ABSTRACT Introduction: Acute severe colitis is a potentially lethal medical emergency and, even today, its treatment remains a challenge for clinicians and surgeons. Intravenous corticoid therapy, which was introduced into the therapeutic arsenal in the 1950s, continues to be the first-line treatment and, for patients who are refractory to this, the rescue therapy may consist of clinical measures or emergency colectomy. Objective: To evaluate the indications for and results from drug rescue therapy (cyclosporine, infliximab and tacrolimus), and to suggest a practical guide for clinical approaches. Methods: The literature was reviewed using the Medline/PubMed, Cochrane library and SciELO databases, and additional information from institutional websites of interest, by cross-correlating the following keywords: acute severe colitis, fulminating colitis and treatment. Results: Treatments for acute severe colitis have avoided colectomy in 60-70% of the cases, provided that they have been started early on, with multidisciplinary follow-up. Despite the adverse effects of intravenous cyclosporine, this drug has been indicated in cases of greater severity with an imminent risk of colectomy, because of its fast action, short half-life and absence of increased risk of surgical complications. Therapy using infliximab has been reserved for less severe cases and those in which immunosuppressants are being or have been used (AZA/6-MP). Indication of biological agents has recently been favored because of their ease of therapeutic use, their good short and medium-term results, the possibility of maintenance therapy and also their action as a "bridge" for immunosuppressant action (AZA/6-MP). Colectomy has been reserved for cases in which there is still no response five to seven days after rescue therapy and in cases of complications (toxic megacolon, profuse hemorrhage and perforation). Conclusion: Patients with a good response to rescue therapy who do not undergo emergency operations should be considered for maintenance therapy using azathioprine. A surgical procedure is indicated for selected cases.

RESUMO Racional: A colite aguda grave é emergência médica, potencialmente letal e o seu tratamento permanece ainda nos dias de hoje um desafio para o clínico e cirurgião. A corticoterapia intravenosa introduzida no arsenal terapêutico na década de 50 permanece como primeira linha de tratamento, e nos pacientes refratários a tal medida, a terapia de resgate pode ser com medidas clínicas ou colectomia de urgência. Objetivo: Avaliar os resultados da terapia de resgate medicamentosa (ciclosporina, infliximabe e tracolimus), suas indicações e resultados, e sugerir um guia prático para abordagem clínica. Métodos: Foi realizada revisão na literatura utilizando as bases Medline/Pubmed, Cochrane Library, Scielo, e informações adicionais em sites institucionais de interesse cruzando os descritores: colite aguda grave, colite fulminante e tratamento. Resultados: O tratamento da colite aguda grave tem evitado a colectomia em 60- 70% dos casos, desde que iniciado precocemente e com acompanhamento multidisciplinar. A ciclosporina intravenosa apesar de seus efeitos adversos, tem sido indicada naqueles casos mais graves com risco iminente de colectomia, pela sua rapidez de ação, meia-vida curta, e não aumentar os riscos de complicações cirúrgicas. A terapia com infliximabe tem sido reservada para os casos menos graves e naqueles em uso ou já expostos a imunossupressores (AZA/6-MP). A facilidade terapêutica, seus bons resultados a curto e médio prazo, a possibilidade de terapia de manutenção e também por agir como "ponte" para ação de imunossupressores (AZA/6-MP) tem recentemente favorecido a indicação de biológicos. A colectomia fica reservada para casos que não apresentaram resposta a terapia de resgate após cinco a sete dias de tratamento e nas complicações (megacólon tóxico, hemorragia profusa e perfuração). Conclusõe s: Os pacientes com boa resposta à terapia de resgate e não submetidos à operações de urgência, deverão ser considerados para terapia de manutenção com azatioprina, sendo procedimento cirúrgico indicado para casos selecionados.

A young leukemic patient with unusual catastrophic intestinal complication.

A 14-year-old child with acute lymphoblastic leukemia who had completed induction chemotherapy presented with fever and diffuse musculoskeletal pains which was thought to be a constellation of myositis, arthralgias and arthritis. Investigations revealed initially showed normal peripheral blood counts but had pancytopenia and pre-terminally blasts were seen in the peripheral blood smear. He had bone marrow necrosis. Disseminated intravascular coagulation was suspected with a positive fungal serology. At autopsy, he had evidence of disease relapsed in lymph nodes, liver, spleen, testes and kidneys. There was extensive pseudomembranous colitis and appendicitis with changes of toxic megacolon.

Toxic Megacolon Associated with Secondary Amyloidosis: An Unusual Complication of Clostridium difficile Colitis / 이화의대지

Amyloidosis is characterized by extracellular deposition of protein fibrils in one or multiple organs. AA amyloidosis is secondarily occurred to be related with chronic infections or inflammatory diseases. We report a 67-year-old man suffered from secondary AA amyloidosis related with chronic Clostridium difficile colitis after repeated total hip replacement surgery. Infection control is the most important treatment of AA amyloidosis secondary to chronic infection. However, the patient's C. difficile colitis was not controlled well, eventually toxic megacolon with sepsis was developed. Consequently, he had to take total colectomy, but he expired with multi-organ failures. We suggested that early surgical procedure might be one option for intractable C. difficile colitis complicated with secondary amyloidosis.

A Case of Toxic Megacolon Associated with Fulminant Pseudomembranous Colitis / 대한소화기내시경학회지

The clinical presentation of Clostridium difficile infection ranges from asymptomatic carriage, colitis with or without pseudomembranes, to fulminant colitis. Although not common, fulminant Clostridium difficile colitis can result in bowel perforation and peritonitis with a high mortality rate. We report a case of toxic megacolon associated with fulminant pseudomembranous colitis. We experienced a case of a 65-year-old male patient who presented with abdominal distension and pain for three days during treatment of pneumonia. We were able to diagnose the case as a toxic megacolon associated with fulminant pseudomembranous colitis. In spite of oral metronidazole treatment and conservative treatment, the clinical course worsened and the patient went into septic shock. The patient underwent a total colectomy but the clinical situation did not improve and the patient died.

A Case of Transverse Colon Perforation after Colonoscopy in a Patient withEnterocolitis Caused by Non-typhoidal Group D Salmonella / 대한소화기내시경학회지

Clinical manifestations of Salmonella infection are variable such as enterocolitis, bacteremia, enteric fever, focal infection and asymptomatic carrier status. Among these presentations, enterocolitis is the most common clinical manifestation and can be diagnosed by the use of fecal specimens. Patients with severe infectious colitis are at increased risk of developing a colon perforation after colonoscopy due to colon trauma. We report a case of a 31-year-old woman with transverse colon perforation after colonoscopy that was diagnosed with enterocolitis caused by infection with non-typhoidal group D Salmonella.
