The HIV-associated lipodystrophy syndrome is reported with an increasing incidence predominantly in HIV-seropositive patients on antiretroviral therapy. The core of the lipodystrophy syndrome consists of fat loss in face, extremities and buttocks with or without a visceral fat accumulation, hyperlipidemia and a disturbed glucose metabolism are considered essential parts of the syndrome too. Additional metabolic abnormalities are regarded as syndrome related.
Currently identified risk factors associated with the development of lipodystrophy are antiretroviral treatment (duration, number and kind of drugs), low CD4 cell count, higher age and metabolic abnormalities. The currently favored hypotheses to explain the lipodystrophy syndrome are essentially based on the assumption that antiretroviral treatment is the cause of the disorder.
The short-term benefit of antiretroviral treatment is greater than the disadvantages of the lipodystrophy syndrome, in the long term, however, the cardiovascular risk associated with the metabolic disturbances may result in an increased mortality on its own. The current approach to treatment includes modification of antiretroviral therapy and specific treatment of symptoms.
据报道,与HIV相关的脂肪代谢障碍综合征发病率日益上升,主要见于接受抗逆转录病毒治疗的HIV血清反应阳性患者。脂肪代谢障碍综合征的核心表现为面部、四肢和臀部脂肪减少,伴或不伴有内脏脂肪堆积,高脂血症和糖代谢紊乱也被视为该综合征的重要组成部分。其他代谢异常也被认为与该综合征相关。
目前已确定与脂肪代谢障碍发生相关的危险因素包括抗逆转录病毒治疗(疗程、药物数量和种类)、CD4细胞计数低、年龄较大以及代谢异常。目前用于解释脂肪代谢障碍综合征的主流假说是基于抗逆转录病毒治疗是该疾病病因这一假设。
抗逆转录病毒治疗的短期益处大于脂肪代谢障碍综合征的弊端,但从长远来看,与代谢紊乱相关的心血管风险本身可能导致死亡率上升。目前的治疗方法包括调整抗逆转录病毒治疗方案以及对症治疗。
