ABSTRACT
A common criticism of the classification of lupus nephritis is the relative scarcity of information regarding tubular, interstitial, and vascular changes compared to the available information regarding glomerular changes, even though their potential for independent progression is known. This study reviewed the importance of less explored lesions by the current and widely used 2003 classification of lupus nephritis of the International Society of Nephrology/Renal Pathology Society (ISN/RPS), with emphasis on the tubulointerstitial, podocyte, and vascular lesions, increasingly recognised as being important in the pathogenesis and prognosis of the disease. Recognition of these lesions can help with therapeutic decision-making, thereby allowing better results for patients with systemic lupus erythematosus.
ABSTRACT
Clinical presentations of the novel coronavirus (SARS-CoV-2) infection are quite varied, ranging from asymptomatic conditions to potentially fatal disease. The kidney is one of the affected targets of coronavirus disease (COVID-19) complications, and renal dysfunction is a significant prognostic factor for mortality. This report describes a series of clinical complications in a previously healthy child who developed nephritic syndrome with a concomitant SARS-CoV-2 infection. These complications include acute kidney injury that progressed to chronicity, multisystemic inflammatory syndrome, Kawasaki-like syndrome, and thrombotic microangiopathy.
