Coronavirus disease 2019 (COVID-19) is a contagious disease that has a potential of causing cardiovascular illness. Cardiac outcomes of COVID-19 mainly include acute coronary syndrome, heart failure, and left ventricular dysfunction. However, pericardial involvement is very rare. Here, we present a case of pericarditis and pericardial effusion in a known hypertensive COVID-19 patient. Our case was a diagnostic dilemma as the literature review mentioned that cardiovascular manifestations are mostly reported in symptomatic and critically ill patients of COVID-19. However, this patient has no viral respiratory illness, and is otherwise healthy.

This report evaluates plasma protein patterns, dialysates and protein analysis of used dialysis membranes from the same patient under hemodialysis in three separate modalities, using high-flux membranes in concentration-driven transport (HD), convection-driven hemofiltration (HF) and combined hemodialfiltration (HDF). The plasma protein changes induced by each of the three dialysis modalities showed small differences in proteins identified towards our previous plasma analyses of chronic kidney disease (CKD) patients. The used dialysate peptide concentrations likewise exhibited small differences among the modalities and varied in the same relative order as the plasma changes, with protein losses in the order HD>HDF>HF. The membrane protein deposits allowed quantification of the relative Hb removal ratios as ~1.7 for HD and ~1.2 for HDF vs. ~1.0 for HF. Hence, plasma protein alterations, dialysate peptide contents and membrane Hb deposits all identify HD as the modality with the most extensive filtration results and exemplifies the accessibility of protein analysis of used membrane filters for evaluation of dialysis efficiencies.
