“…Although some isolated case reports of pH1N1-associated rhabdomyolysis have been published [18][19][20][21][22], uncertainty still remains regarding the clinical implications of elevated creatine kinase levels. While the association of elevated CK with requirement for RRT has been documented at CK level around 11,000 UI/L in several pH1N1 case reports [23,24], others have failed to demonstrate a need for RRT, even at levels of CK of 16,000 UI/L and above [22,25,26]. A series of case reports showed elevated levels (1,000-5,000 UI/L) of CK in severe presentations of pH1N1 infection [27], and one case report showed AKI due to pH1N1-induced rhabdomyolysis (with CK levels above 40,000 UI/L) [28].…”
