%X Objectives: To determine the clinical and laboratory predictors of fatality among patients with Hantavirus infection.Materials and methods: A retrospective study was conducted on the patients with Hantavirus infection between April 2009and October 2011 at the Black Sea and the Mediterranean regions in Turkey. Demographic, clinical and laboratory findings offatal cases and non-fatal cases at the admission were compared.Results: Twenty-two patients with confirmed Hantavirus infection were evaluated. Five patients died (22.7%). The cause ofdeath was massive bleeding. The rate of hemorrhage was significantly higher in the fatal cases than non-fatal cases (p<0.001).Massive gastrointestinal hemorrhage was seen in four of these patients, cerebral hemorrhage in two and both gastrointestinaland pulmonary hemorrhage in one. Disseminated intravascular coagulation (DIC) was present in four of the fatal cases and aremarkable cause of the bleeding (p=0.02). White blood cell count (WBC) (p=0.002), creatine phosphokinase (CPK) (p=0.011),blood-urea-nitrogen (BUN) (p=0.014), C reactive protein (CRP) (p=0.005) and D-dimer levels (p=0.001), prothrombin time (PT)(p=0.023), activated partial thromboplastin time (aPTT) (p=0.001) and international normalized ratio (INR) (p=0.021) were significantlyhigher, and platelet counts (p=0.038) significantly lower in the fatal cases. Optimum diagnostic cut-off points for specificlaboratory parameters which may be predictive of fatality were; WBC=16,000 ¦ÌL-1, PLT=30000 ¦ÌL-1, PT=19.7 s, aPTT=36s, INR=1.2, D-dimer=9.3 ¦Ìg/mL, CPK=600 U/L, BUN=47 mg/dL and CRP=13.4 mg/dL.Conclusions: Physicians should be aware of the high fatality risk for patients with Hantavirus infection with hemorrhage, elevatedWBC, CPK, BUN, CRP, PT, aPTT, INR and D-dimer and reduced platelet counts.
