Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

Management of BK virus-associated haemorrhagic cystitis in allogeneic stem cell transplant recipients

BK virus (BKV)-related haemorrhagic cystitis (HC) is an important cause of morbidity following allogeneic haematopoietic stem cell transplantation (HSCT). The various risk factors include high-level BKV viruria and/or viremia, myeloablative conditioning, acute graft versus host disease (GVHD), cytomegalovirus viremia, and unrelated or HLA-mismatched donor. The presence of high plasma BK viral load and cytopenias have been implicated as important predictors for protracted disease course. These patients frequently require hospitalisation which may extend for several weeks. Supportive measures in the form of analgesics, intravenous hydration, bladder irrigation, and transfusion support remain the mainstay of management. Various drugs have been used with limited success in this setting. These include antiviral drugs, fluoroquinolones, leflunomide, growth factors, clotting factors, estrogens, and prostaglandins. The role of adoptive cellular immunotherapy has also been explored but lacks clinical validation. The strategies aimed at expediting urothelial repair like hyperbaric oxygen therapy (HBOT), intravesical fibrin glue and platelet-rich plasma (PRP) are emerging. Some patients with severe disease do require surgical intervention to relieve urinary obstruction. The frequent co-occurrence of acute GVHD and CMV disease further complicates the management in such patients. There is an unmet need for effective and evidence-based options for the prevention and management of this disease. Due to lack of robust data supported by randomised trials, the acceptability of the available guidelines to simplify the treatment is expected to be low. Despite the availability of various treatment options, the management of BKV-related HC in day-to-day practice continues to be a challenge. The aim of this article is to put forward an up-to-date review of the preventive and therapeutic strategies for BKV-related HC

Clinical Profile and Renal Survival of Anti-Glomerular Basement Membrane Disease Patients: A Retrospective Case Series from Northern India

Introduction: Anti-glomerular basement membrane (anti-GBM) disease is a rare organ-specific autoimmune disease. The overall and renal outcomes of patients have mostly been reported in small-sized cohorts. We aimed to study the clinical profile, overall survival, and renal survival of anti-glomerular basement membrane disease patients at our center. Methods: We conducted a retrospective analysis of the data regarding the clinical profile and renal survival of patients diagnosed with anti-GBM disease from October 2019 to March 2022, having a minimum follow-up of 12 months. Results: There were 15 patients in the study, with the mean age of presentation being 51.6 ± 13.7 years. The median duration of symptoms onset to the nephrologist opinion was 15 (10–23) days. The extrarenal manifestations were seen in the respiratory, otorhinolaryngological, and neurological systems. The mean serum anti-GBM titers were 154.5 (14.9–263.5) U/mL. Serum anti-GBM titers were present in 13/15 (86.6%) patients, and 12/13 (92.3%) patients had above the reference range. Anti-neutrophil cytoplasm antibody (ANCA) levels were assessed in 12/15 (80%) patients, and 9/12 (75%) had higher levels. Renal biopsy was available in 14 patients with more than 50% crescents. Along with crescents, necrotizing lesions, rupture of the Bowman’s capsule, and granulomatous lesions were also seen. Among the initial therapies, the steroid pulse was given to 13 (86.6%) patients, whereas membrane plasmapheresis was given to 8 (53.3%) patients. Inj. cyclophosphamide and inj. rituximab were given to 8 (53.3%) and 4 (26.6%) patients, respectively. No difference was seen in clinical characteristics, renal biopsy features, treatment received, and outcomes with ANCA positivity except for age, where patients who were ANCA positive were older compared to patients who were ANCA negative. One-year renal and patient survival was seen in 4 (26.6%) and 6 (40%) patients, respectively. Conclusion: Most patients of anti-GBM disease have active sediments, raised creatinine, and non-specific symptomatology. There is poor renal and patient outcome as most patients present with advanced renal failure
