[Clinical cases of complicated diverticulitis against the background of severe course COVID-19. Case report].

Two clinical cases of perforation of a previously undiagnosed colon diverticulum in patients with coronavirus infection caused by the SARS-CoV-2 virus treated at the Hospital №1 of Nalchik. Both patients were elderly, overweight, had a lot of chronic concomitant diseases. Patients received hormone therapy and were targeted: the first patient twice (tocilizumab on the first day of hospitalization and olokizumab on the 7th day of inpatient treatment). The second patient received levilimab on the 3rd day of his stay in the hospital. A short time after targeting, both patients developed acute diffuse abdominal pain, the patients were transferred to the surgical department and operated on. During the operation, both patients were found to have previously undiagnosed diverticular disease, complicated by diverticular perforation and peritonitis on the background of immunosuppression. Both patients died. Thus, when using targeted therapy for patients with COVID-19, it is necessary to take into account that they may have previously undiagnosed chronic diseases that can cause fatal complications against the background of immunosuppression.

Utility of monocyte distribution width in the differential diagnosis between simple and complicated diverticulitis: a retrospective cohort study.

BACKGROUND: Colonic diverticulitis is a leading cause of abdominal pain. The monocyte distribution width (MDW) is a novel inflammatory biomarker with prognostic significance for coronavirus disease and pancreatitis; however, no study has assessed its correlation with the severity of colonic diverticulitis. METHODS: This single-center retrospective cohort study included patients older than 18 years who presented to the emergency department between November 1, 2020, and May 31, 2021, and received a diagnosis of acute colonic diverticulitis after abdominal computed tomography. The characteristics and laboratory parameters of patients with simple versus complicated diverticulitis were compared. The significance of categorical data was assessed using the chi-square or Fisher's exact test. The Mann-Whitney U test was used for continuous variables. Multivariable regression analysis was performed to identify predictors of complicated colonic diverticulitis. Receiver operator characteristic (ROC) curves were used to test the efficacy of inflammatory biomarkers in distinguishing simple from complicated cases. RESULTS: Of the 160 patients enrolled, 21 (13.125%) had complicated diverticulitis. Although right-sided was more prevalent than left-sided colonic diverticulitis (70% versus 30%), complicated diverticulitis was more common in those with left-sided colonic diverticulitis (61.905%, p = 0.001). Age, white blood cell (WBC) count, neutrophil count, C-reactive protein (CRP) level, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and MDW were significantly higher in the complicated diverticulitis group (p < 0.05). Logistic regression analysis indicated that the left-sided location and the MDW were significant and independent predictors of complicated diverticulitis. The area under the ROC curve (AUC) was as follows: MDW, 0.870 (95% confidence interval [CI], 0.784-0.956); CRP, 0.800 (95% CI, 0.707-0.892); NLR, 0.724 (95% CI, 0.616-0.832); PLR, 0.662 (95% CI, 0.525-0.798); and WBC, 0.679 (95% CI, 0.563-0.795). When the MDW cutoff was 20.38, the sensitivity and specificity were maximized to 90.5% and 80.6%, respectively. CONCLUSIONS: A large MDW was a significant and independent predictor of complicated diverticulitis. The optimal cutoff value for MDW is 20.38 as it exhibits maximum sensitivity and specificity for distinguishing between simple and complicated diverticulitis The MDW may aid in planning antibiotic therapy for patients with colonic diverticulitis in the emergency department.

Acute Cholecystitis and Diverticular Abscess Patient with COVID-19 Infection.

This is a case of a 53-year-old African American woman with newly diagnosed concomitant acute cholecystitis, diverticulitis, and SARS-COV-2 infection. She underwent treatment for COVID-19 with antibiotics and supportive treatment, and on day 32 after initial symptoms presented, she had an elective laparoscopic cholecystectomy. Our patient was one of the first cases to present with acute cholecystitis and diverticulitis complicated by COVID-19, and serves as a template for surgical management of non-emergent abdominal pathologies in the midst of the COVID-19 pandemic.

Voici le cas d'une Afro-Américaine de 53 ans chez qui on a diagnostiqué récemment une cholécystite aiguë concomitante, une diverticulite et une infection par le SRAS-COV-2. Elle a été traitée pour l'infection COVID-19 avec des antibiotiques et un traitement de soutien, et le 32e jour après l'apparition des premiers symptômes, elle a subi une cholécystectomie laparoscopique élective. Notre patiente a été l'un des premiers cas à présenter une cholécystite et une diverticulite aiguës compliquées par le COVID-19, et sert de modèle pour la gestion chirurgicale des pathologies abdominales non urgentes au milieu de la pandémie de COVID-19.
