Severe acute respiratory syndrome coronavirus 2 (SARS COV-2) activate and enhances complement mediated cell destruction through membrane attack complex (MAC) formation (Ting Gao, 2020) [6]. In paroxysmal nocturnal hemoglobinuria (PNH) there is deficiency of complement regulatory proteins (CD55 and CD59) which enhances the red blood cells (RBC) to lysis by MAC (Rother, 2005) [3]. SARS COV-2 causes complement activation on the other hand individuals with PNH is vulnerable to complement mediated destruction of RBC. In PNH when massive hemolysis occur hemosiderin become deposited in renal tubule causing acute renal tubular necrosis (ATN). If it is diagnosed and treated early it may be reversible but if remain untreated it may progress to chronic kidney disease (CKD) as occur in this patient (Hussain S, 2013) [1]. Individual with PNH when superadded with COVID-19 infection it should be treated with extreme caution to prevent multiple complications.
