Hepatitis C virus (HCV) is one of the most common infections among hemodialysis (HD) patients. It continues to be exasperating problem in many HD centers, in spite of strictly following infection and quality control measures.
This is a multi-center retrospective comparative study, carried out in different HD units of Menoufia Governorate, Egypt. Patients who were HCV negative on starting HD were divided into two groups; Group-1 included patients who remained negative for HCV and group-2 included patients who seroconverted to HCV positive status during dialysis. Risk factors for seroconversion were compared between the two groups.
Out of the 514 surveyed patients, 259 were negative for HCV and 255 were positive; the prevalence of HCV infection was 49.6%. A total of 303 patients who were HCV negative on starting HD were recruited in the study. Group-1 included 259 patients who remained negative for HCV and group-2 included the 44 patients who seroconverted to HCV positive status during dialysis. Patients in group-2 had significantly longer duration on dialysis compared to group-1 (71 .4 versus 33.7 months) and they had stronger family history of HCV infection (20.5% versus 6.4%).
There is high prevalence and high seroconversion rate of HCV in surveyed HD units. Following infection control measures and strict supervision of dialysis staff should be emphasized. More studies are needed to evaluate the possible benefits of isolation protocols of HCV patients on regular HD.
丙型肝炎病毒(HCV)是血液透析(HD)患者中最常见的感染之一。尽管严格遵循感染控制和质量控制措施,但在许多血液透析中心,这仍然是一个令人头疼的问题。
这是一项在埃及梅努菲亚省不同血液透析单位开展的多中心回顾性比较研究。开始血液透析时HCV阴性的患者被分为两组;第1组包括HCV仍为阴性的患者,第2组包括在透析期间血清转化为HCV阳性状态的患者。比较两组之间血清转化的危险因素。
在514名接受调查的患者中,259名HCV阴性,255名阳性;HCV感染患病率为49.6%。共有303名开始血液透析时HCV阴性的患者纳入本研究。第1组包括259名HCV仍为阴性的患者,第2组包括44名在透析期间血清转化为HCV阳性状态的患者。与第1组相比,第2组患者的透析时间明显更长(71.4个月对33.7个月),且他们有更强的HCV感染家族史(20.5%对6.4%)。
在所调查的血液透析单位中,HCV患病率和血清转化率都很高。应强调遵循感染控制措施并对透析工作人员进行严格监督。需要更多研究来评估对常规血液透析的HCV患者采用隔离方案可能带来的益处。
