Background The COVID-19 pandemic has led to significant reductions in transplantation, motivated in part by concerns of disproportionately more severe disease among solid organ transplant (SOT) recipients. However, clinical features, outcomes, and predictors of mortality in SOT recipients are not well-described. Methods We performed a multi-center cohort study of SOT recipients with laboratory-confirmed COVID-19. Data were collected using standardized intake and 28-day follow-up electronic case report forms. Multivariable logistic regression was used to identify risk factors for the primary endpoint, 28-day mortality, among hospitalized patients. Results Four hundred eighty-two SOT recipients from >50 transplant centers were included: 318 (66%) kidney or kidney/pancreas, 73 (15.1%) liver, 57 (11.8%) heart, and 30 (6.2%) lung. Median age was 58 (IQR 46-57), median time post-transplant was 5 years (IQR 2-10), 61% were male, and 92% had ≥1 underlying comorbidity. Among those hospitalized (376 [78%]), 117 (31%) required mechanical ventilation, and 77 (20.5%) died by 28 days after diagnosis. Specific underlying comorbidities (age >65 [aOR 3.0, 95%CI 1.7-5.5, p<0.001], congestive heart failure [aOR 3.2, 95%CI 1.4-7.0, p=0.004], chronic lung disease [aOR 2.5, 95%CI 1.2-5.2, p=0.018], obesity [aOR 1.9, 95% CI 1.0-3.4, p=0.039]) and presenting findings (lymphopenia [aOR 1.9, 95%CI 1.1-3.5, p=0.033], abnormal chest imaging [aOR 2.9, 95%CI 1.1-7.5, p=0.027]) were independently associated with mortality. Multiple measures of immunosuppression intensity were not associated with mortality. Conclusions Mortality among SOT recipients hospitalized for COVID-19 was 20.5%. Age and underlying comorbidities rather than immunosuppression intensity-related measures were major drivers of mortality.

This survey suggests that clinical practice patterns among gastroenterologists and hepatologists for the management of NASH frequently diverge from published practice guidelines. Although liver biopsy remains the gold standard to diagnose NASH, less than 25% of respondents routinely require it to make the diagnosis of NASH. We conclude that NASH is underdiagnosed in gastroenterology and hepatology practices, highlighting the need to refine noninvasive diagnostic tools.

We found that patients do not report the majority of their symptoms during ambulatory reflux monitoring even within a 5-min time window of the true event and advise caution in clinical decision-making based solely on symptom indices.

We report a 43-year-old man who presented for evaluation of ascites, varices, and hepatosplenomegaly. Initial labs were notable for normal platelets, mild liver synthetic dysfunction, and disproportionately elevated alkaline phosphatase. He was presumed to have underlying cirrhosis, and diuresis was attempted without success. A transjugular liver biopsy showed marked sinusoidal dilation without cirrhosis. Diagnostic paracentesis revealed fluid studies suggestive of cardiac ascites. Further cardiac evaluation confirmed constrictive pericarditis. The case highlights the importance of considering a broad differential in the evaluation of ascites.

Background. Oxidative stress is crucial in developing broad spectrum of diseases, including atherosclerosis and related life-threatening conditions, such as acute coronary syndrome (ACS) mainly caused by atherosclerotic plaque vulnerability. Objective. To clarify the relation between oxidative stress and plaque instability we decided to compare oxidative profiles of patients with acute coronary syndrome (ACS) and with chronic coronary syndrome (CCS), evaluated at admission to the coronary care unit (CCU) of LTD Clinic-LJ (Kutaisi, Georgia) in April 2018 - June 2019, who underwent successful primary percutaneous coronary intervention (PCI). Methods. 191 patients were enrolled (100 patients with ACS in Group 1 and 91 patients with CCS in Group 2) into the study. Using the CR3000 FORM PLUS (Callegari Srl, Catellani Group, Italy) – Callegari Point of Care instrument we evaluated free oxygen radical test (FORT), free oxygen radicals defense (FORD), calculated REDOX Index and the overall Profile of oxidative stress. Results. The mean/median concentration of Free Oxygen Radicals was significantly higher in the patients with ACS (404.37±9.83 Fort units/2.36 mmol/l H2O2 eq. vs 282.34±9.83 Fort units/2.36 mmol/l H2O2 eq., p<0.0001). Significant correlation was found between advanced oxidative stress and acute coronary syndrome (OR 14.42 95% CI (7.08-29.4), RR 3.26 95% CI (2.31-4.60) with high diagnostic characteristics (sensitivity of 82% and specificity of 92.3%; positive predictive value of 92% and positive likelihood ratio of 11). Conclusion. Oxidative stress is crucial in life-threatening acute coronary events. Measurement of overall oxidative stress profile, as a surrogate of plaque instability and rupture predictor, could help the clinicians in risk stratification and prevention of acute coronary syndrome (ACS).
