Lipodystrophy syndrome (LD) is common in HIV-infected children, particularly those taking didanosine, stavudine or zidovudine. Lipo-atrophy in particular causes major stigmatisation and interferes with adherence. In addition, LD may have significant long-term health consequences, particularly cardiovascular. Since the stigmatising fat distribution changes of LD are largely permanent, the focus of management remains on early detection and arresting progression. Practical guidelines for surveillance and avoidance of LD in routine clinical practice are presented. The diagnosis of LD is described and therapeutic options are reviewed. The most important therapeutic intervention is to switch the most likely offending antiretroviral to a non-LD-inducing agent as soon as LD is recognised. Typically, when lipoatrophy or lipohypertrophy is diagnosed the thymidine nucleoside reverse transcriptase inhibitor (NRTI) is switched to a non-thymidine agent such as abacavir (or tenofovir in adults). Where dyslipidaemia is predominant, a dietician review is helpful, and the clinician may consider switching to a protease inhibitor-sparing regimen or to atazanavir.
脂肪代谢障碍综合征(LD)在感染HIV的儿童中很常见,尤其是那些服用去羟肌苷、司他夫定或齐多夫定的儿童。特别是脂肪萎缩会导致严重的污名化,并影响治疗依从性。此外,LD可能会产生重大的长期健康后果,尤其是心血管方面。由于LD导致的具有污名化的脂肪分布变化在很大程度上是永久性的,管理的重点仍然是早期发现和阻止病情进展。本文介绍了在常规临床实践中监测和避免LD的实用指南。描述了LD的诊断方法并对治疗选择进行了综述。最重要的治疗干预措施是一旦确诊LD,就将最有可能导致问题的抗逆转录病毒药物换成不会引起LD的药物。通常,当诊断出脂肪萎缩或脂肪肥大时,将胸苷核苷逆转录酶抑制剂(NRTI)换成非胸苷类药物,如阿巴卡韦(成人用替诺福韦)。如果血脂异常为主,营养师会诊会有帮助,临床医生可考虑换成不含蛋白酶抑制剂的治疗方案或使用阿扎那韦。
