Due to the asymptomatic nature of acute hepatitis C it can be difficult to diagnose in the early stage of infection, but with the higher treatment success rates and reduced treatment duration at this stage, it is imperative that diagnoses are made. Therefore, physicians should routinely screen at-risk individuals and investigate abnormal liver function tests. Serum HCV RNA should be considered in any HCV-antibody-negative individual in whom acute HCV is clinically suspected, or annually in those high-risk individuals with previous infection. Acute hepatitis C transmission may be facilitated by the presence of an erosive genital lesion, such as syphilis or lymphogranuloma venereum, and thus testing at this time should be encouraged. Reinfection with HCV does occur and patients need to be informed of the sexual and other high-risk behaviors that put them at risk of reinfection. Public awareness of the possibility of HCV infection, and subsequent reinfection, in high-risk groups should be increased. The question of the optimal treatment regimen is still disputed. However, ongoing trials and the proposed randomized controlled trial from the European AIDS Treatment Network should answer many of our questions. In the meantime, units faced with HIV/acute hepatitis C coinfection should follow recommendations from the HCV-HIV International Panel.
由于急性丙型肝炎具有无症状的特性,在感染早期可能难以诊断,但鉴于此阶段治疗成功率较高且治疗疗程缩短,进行诊断势在必行。因此,医生应定期对高危个体进行筛查,并对肝功能检查异常情况展开调查。对于临床怀疑为急性丙型肝炎的任何丙型肝炎抗体阴性个体,或既往感染过的高危个体每年都应检测血清丙型肝炎病毒核糖核酸(HCV RNA)。糜烂性生殖器病变(如梅毒或性病性淋巴肉芽肿)可能会促使急性丙型肝炎传播,因此此时应鼓励进行检测。丙型肝炎病毒再次感染确实会发生,需要告知患者存在使其面临再次感染风险的性行为及其他高危行为。应提高高危人群对丙型肝炎病毒感染及后续再次感染可能性的公众认知。最佳治疗方案的问题仍存在争议。然而,正在进行的试验以及欧洲艾滋病治疗网络提议的随机对照试验应能解答我们的许多问题。与此同时,面临人类免疫缺陷病毒(HIV)/急性丙型肝炎合并感染的科室应遵循丙型肝炎病毒-人类免疫缺陷病毒国际专家组的建议。
