Abstract
Crimean Congo Hemorrhagic Fever (CCHF) is an acute and fatal disease with various clinical and paraclinical characteristics. In this article, we report data on confirmed CCHF cases from Iran and describe the association between studying factors and outcomes of the disease. In the study design, we evaluated demographic characteristics, clinical, laboratory and sonographic findings of 160 CCHF confirmed cases during 2003 and 2012 in Zabol (A city in Sistan and Baluchestan province of Iran). The association between these factors and the fatal outcome were evaluated by regression analysis. The disease had a fatal outcome in 7 (4.4%) patients. Females had more severe symptoms and higher odds for death (odds ratio11.57, p=0.005). Leukocytosis (p<0.001), PT (p<0.001) and PTT (p=0.008) elongation, AST (p=0.010) and ALT (p>0.001) elevation were significantly associated with fatal outcome. CNS related symptoms (odds ratio 5.9, p=0.027) in clinical examination and ascites (odds ratio 38.4, p=0.012) and liquid in the pelvic cavity (odds ratio 24.2, p=0.004) were also identified as risk factors of death in this study. Our data suggest that in addition to clinical and laboratory findings practitioners consider sonography for CCHF prognosis.
