ABSTRACT

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.

ABSTRACT

BACKGROUND: Blunt chest trauma and its complications are commonly encountered in emergency medicine. Herein, we used a rat model to investigate the role of thoracic trauma in inflammation, apoptosis and bacterial translocation following multiple traumas. METHODS: Ninety Wistar rats were divided equally into nine groups. Rats underwent a standardized blunt thoracic and/or head trauma and were sacrificed 24 or 48 hours after the trauma. Specimens from various organs and blood samples were collected and quantitatively cultured for aerobic organisms. Interleukins, TNF-α, and MCP-1 levels were assessed in the sera and markers of apoptosis were detected in the lungs. RESULTS: Levels of interleukins, TNF-α and MCP-1 in all of the groups undergoing trauma were significantly higher than those of the control group (p=0.001). Levels of apoptotic cells in the groups undergoing head and thoracic trauma (HTT) were significantly higher than those of the control group (p=0.009). Light microscopic evaluation indicated that damage in the HTT groups was significantly higher than that in the control group. The incidence of bacterial translocation was also significantly higher in the HTT groups (p=0.003). CONCLUSION: Multiple inflammatory mediators are activated in multiple traumas (including blunt thoracic trauma), which allow bacterial translocation and apoptotic processes to occur. Our results indicate that thoracic trauma plays a major role in post-traumatic bacterial translocation, inflammation, and apoptosis following multiple traumas.
