Human immunodeficiency virus-associated nephropathy (HIVAN) has rarely been reported in African children. In this single-center study, we analyzed ten children diagnosed with HIVAN from January 2000 to October 2006. There were eight boys and two girls, with a male:female ratio of 4:1. Their ages were from 5 months to 15 years (mean 6.8+/-6.2 years), with a peak age of 5-9 years. The presenting complaints included generalized edema (60%) and hypertension (50%). All patients had proteinuria on urine dipstick, with four (40%) at nephrotic range (proteinuria >or=500 mg/dl). Nine (90%) patients were in renal failure, with elevated serum creatinine (6.3-24 mg/dl) and serum urea (70-120 mg/dl). Renal disease was the first manifestation of HIV infection in six patients, whereas the diagnosis was made on autopsy in three. The duration from HIV infection to development of HIVAN ranged from 5 months to 10 years. CD4(+) cell count, done in only three patients due to financial constraints, was below 200/mm(3). The kidneys were hyperechoic on abdominal ultrasound in all patients, and three (30%) showed grossly enlarged kidneys. Histology of renal tissues available by autopsy in three patients showed mainly collapsing focal segmental glomerulosclerosis. Treatments given were angiotensin-converting enzyme (ACE) inhibitors and highly active antiretroviral therapy (HAART) in four and two patients, respectively, and one patient underwent peritoneal dialysis. On outcome analysis, seven (70%) patients died, two were lost to follow-up, and one was alive on HAART therapy at the writing of this article. In conclusion, HIVAN occurs in Nigeria children, and the mortality is very high from uremia.
人类免疫缺陷病毒相关性肾病(HIVAN)在非洲儿童中鲜有报道。在这项单中心研究中,我们分析了2000年1月至2006年10月间确诊为HIVAN的10名儿童。其中有8名男孩和2名女孩,男女比例为4:1。他们的年龄从5个月至15岁(平均6.8±6.2岁),发病高峰年龄为5 - 9岁。主要临床表现包括全身性水肿(60%)和高血压(50%)。所有患者尿试纸检测均有蛋白尿,其中4例(40%)为肾病范围蛋白尿(蛋白尿≥500mg/dl)。9例(90%)患者出现肾衰竭,血清肌酐(6.3 - 24mg/dl)和血清尿素(70 - 120mg/dl)升高。肾病是6例患者HIV感染的首发表现,而3例是在尸检时确诊。从HIV感染到发展为HIVAN的时间为5个月至10年。由于经济限制,仅3例患者检测了CD4(+)细胞计数,均低于200/mm³。所有患者腹部超声显示肾脏回声增强,3例(30%)肾脏明显增大。3例尸检患者的肾组织病理学检查主要显示塌陷型局灶节段性肾小球硬化。分别有4例和2例患者接受了血管紧张素转换酶(ACE)抑制剂和高效抗逆转录病毒治疗(HAART),1例患者接受了腹膜透析。在预后分析中,7例(70%)患者死亡,2例失访,1例在撰写本文时接受HAART治疗存活。总之,HIVAN在尼日利亚儿童中存在,且因尿毒症导致的死亡率很高。
