In December 2019, a series of pneumonia cases of unknown etiology, which were epidemiologically linked to a seafood market, was reported in Wuhan, Hubei province, China. The disease has rapidly spread around the world, becoming a global pandemic. A coronavirus, which was named 2019 novel coronavirus (2019-nCov), was isolated from respiratory tract samples1 and later identified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The name of the disease was officially changed to coronavirus disease 2019 (COVID-19). Pulmonary involvement with alveolar damage and acute respiratory failure has been the most remarkable clinical condition of COVID-19 patients. However, there is increasing evidence that this virus also affects other organs, kidney injury being relatively common in this infection and associated with an increased mortality rate.2 In a large prospective cohort of 701 COVID-19 patients in China, 44% had proteinuria and 27% had hematuria on admission. During hospitalization, 5.1% of them developed acute kidney injury.2 We report a patient who developed systemic symptoms and renal involvement after being hospitalized because of a COVID-19 infection. A mesangial proliferation and IgA deposits in the glomeruli were seen on the kidney biopsy specimen.

Background: Chronic fluid overload is frequent in hemodialysis patients (P) and it associates with hypertension, left ventricular hypertrophy (LVH) and higher mortality. Moreover, echocardiographic data assessing fluid overload is limited. Our aim was to evaluate the relationship between fluid overload measured by bioimpedance spectroscopy (BIS) and different echocardiographic parameters. Methods: Cross-sectional observational study including 76 stable patients. Dry weight was clinically assessed. BIS and echocardiography were performed. Weekly time-averaged fluid overload (TAFO) and relative fluid overload (FO/ECW) were calculated using BIS measurements. Results: Based on TAFO three groups were defined: A- dehydrated, TAFO < -0.25 L 32 P (42%); B- normohydrated, TAFO between -0.25 and 1.5 l: 26 (34%); C- overhydrated, TAFO>1.5 l: 18 (24%). We found significant correlation between TAFO and left atrial volume index (LAVI) (r: 0.29; p = 0.013) but not with FO/ECW (r: 0.06; p = 0.61). TAFO, but not FO/ECW kept a significant relationship with LAVI (p = 0.03) using One-Way ANOVA test and linear regression methods. LVH was present in 73.7% (concentric 63.2%, eccentric in 10.5%). No differences between groups in the presence of LVH or left ventricular mass index were found. Conclusions: We found that left atrial volume index determined by echocardiographic Area-length method, but not left ventricle hypertrophy or dimensions of cavities, are related on hydration status based on bioimpedance measured time-averaged fluid overload (TAFO), and not with FO/ECW.
