Distribution of hepatitis C virus genotypes among intravenous drug users in the Çukurova region of Turkey.

BACKGROUND/AIM: The most common hepatitis C virus (HCV) genotype in Turkey is genotype 1. However, there has not been a study about the distribution of HCV genotypes among intravenous drug users (IVDUs) in the Çukurova region of Turkey. This study was planned to understand if there is a difference between IVDUs and the normal population. MATERIALS AND METHODS: Between May 2010 and May 2014, anti-HCV positive IVDUs who applied to the 6 hospitals in the Çukurova region of Turkey were included in this study. Their HCV genotypes were studied. RESULTS: Ninety-seven anti-HCV positive IVDUs were screened in terms of HCV RNA and genotype. Ten were excluded from the study because their HCV RNA results were negative. Fifty-one of the 87 patients (58.6%) had genotype 3. Genotype 2 was detected in 26 (29.9%) and genotype 1 was detected in 10 (11.5%) patients. CONCLUSION: HCV genotypes seem to be different between the normal population and IVDUs according to studies worldwide. Among IVDUs, we detected a dominance of genotype 3 and genotype 2, which is apparently different from the normal population. The reason for this difference can be simply explained by infection through shared needles. However, there may still be a different immunological response in IVDUs, the investigation of which may lead to further studies.

Association of insulin resistance, viral load, and adipokine levels with liver histology in patients with chronic hepatitis C: an observational, multicenter study in Turkey.

OBJECTIVE: To evaluate the association of insulin resistance (IR), viral load, and adipokine levels with liver histology in patients with chronic hepatitis C (CHC). PATIENTS AND METHODS: In this noninterventional, multicenter study carried out at 11 infectious diseases clinics in Turkey, 103 CHC patients [mean (SD) age: 50.2 (11.0) years, 60 (58.3%) women] planned to be treated by ribavirin and peginterferon-α2a were included. Data on hepatic fibrosis and steatosis, IR, viral load, and hepatitis C virus-RNA genotyping, adipokine, and cytokine levels were collected. RESULTS: The mean (SD) Knodell score was 8.1 (3.6); grade I steatosis was evident in 46 (44.7%) patients and IR was identified in 56 (54.9%). There was a significant positive correlation of the homeostasis model assessment-IR index with Knodell fibrosis (r=0.235; P=0.027) and hepatic steatosis (r=0.435; P<0.001). There was a significant positive correlation of leptin levels with Knodell fibrosis (r=0.265; P=0.013) and hepatic activity index (r=0.218; P=0.041). Hepatic steatosis was correlated negatively with adiponectin (r=-0.320; P=0.001) and positively with leptin (r=-0.368; P<0.001) levels. Logistic regression analysis showed that increase in age [odds ratio (OR), 1.056; 95% confidence interval (CI), 1.005-1.110; P=0.030] was the only significant predictor of hepatic fibrosis (OR, 1.056; 95% CI, 1.005-1.110; P=0.030), whereas increase in age (OR, 1.066; 95% CI, 1.006-1.130; P=0.030), the presence of IR (OR, 5.621; 95% CI, 1.547-20.425; P=0.009), and decrease in adiponectin levels (OR, 0.808; 95% CI, 0.682-0.957; P=0.013) were the significant predictors of hepatic steatosis. CONCLUSION: Our findings indicate a significant relationship of hepatic fibrosis and hepatic steatosis with IR and leptin levels, but not with the viral load in Turkish patients with CHC.

Fever of unknown origin in Turkey: evaluation of 87 cases during a nine-year-period of study.

OBJECTIVES: To investigate fever of unknown origin (FUO) in 87 patients. METHODS: We investigated 87 (61 male) patients with FUO using the criteria of Petersdorf and Beeson [Medicine 40 (1961) 1] hospitalized between January 1994 and August 2002 at Cukurova University Hospital. RESULTS: The median age of the patients was 38.5 years (range: 14-80 years). Eleven patients (12.6%) were over 65. The mean duration of hospitalization was 22.5+/-13 days. Infectious diseases were the most common causes of FUO. Tuberculosis (n=15, 17.2%), infective endocarditis (n=6), abdominal abscess (n=6), brucellosis (n=5), urinary tract infection (n=5), visceral leishmaniasis (n=4), salmonellosis (n=3), rhinocerebral mucormycosis (n=4), atypical pneumonia, cerebral toxoplasmosis, Cytomegalovirus infection or encephalitis were diagnosed in 51 (58.6%) patients. The second most common causes of FUO were collagen vascular diseases (n=16, 18.3%) determined as vasculitis syndrome, adult Still's disease (n=4), systemic lupus erythematosus, Behçet's disease, juvenile ankylosing spondylitis. Neoplasm was found in 12 (13.7%) patients; (non-Hodgkin lymphoma, Hodgkin lymphoma, chronic myeloid leukemia, gastrointestinal tract carcinoma, glioma). Miscellaneous diseases thyroiditis, granulomatous hepatitis were diagnosed in two (2.2%) patients. On admission, six patients (6.8%) were neutropenic. CONCLUSIONS: Infectious diseases, especially tuberculosis, were the leading diagnostic category of FUO in this study. Adult Still's disease was more common than expected. An aetiological diagnosis could not be reached in six (7%) patients who were followed for 1 year. Five of these patients completely recovered, and one patient died.
