Pathohistological features of Clostridium difficile-associated pseudomembranous colitis in post-COVID-19 patients
Year: 2025
Type: article
Study design: Case Report
Abstract: AIM: to assess features of pathomorphological changes in the intestinal wall in patients who had new coronavirus infection SARS-CoV-2.PATIENTS AND METHODS: the study included 8 patients who underwent surgery for complications of pseudomembranous colitis and had previously COVID-19. Six patients underwent colectomy, and two underwent subtotal colectomy with end ileostomy. Histology of the removed specimens was standard.RESULTS: in all specimens, in addition to the changes peculiar for pseudomembranous colitis, vascular lesions of the bowel wall were detected as vasculitis of small arteries and vessels of the microcirculatory network, phlebitis and thrombosis of venous vessels like in COVID-19. These pathological changes in blood vessels may reveal the intramural perfusion disorders of blood circulation, leading subsequently to ischemic changes.CONCLUSION: when treating patients with pseudomembranous colitis and postcovid syndrome, it is necessary to take into account the mutually aggravating effect of both diseases, when assessing risks, determining indications for surgery and conservative measures.
