背景:HIV-1阴性疟疾患儿淋巴细胞可逆,CD4计数减少。我们评估了疟原虫血症对 HIV-1 感染者和非 HIV 感染者的绝对 CD4 计数的影响。方法:在赞比亚恩多拉的卫生中心一级,我们治疗了 327 名患有确诊、无并发症的临床疟疾的非怀孕成年人。我们在入组时以及治疗后 28 天和 45 天评估了 HIV-1 状态、CD4 计数和 HIV-1 病毒载量(如果感染 HIV-1)。结果:成功抗疟治疗后,随访第 28 天,HIV-1 阴性患者的中位 CD4 计数从 468 个细胞/μL 增加到 811 个细胞/μL,HIV-1 阳性患者的中位 CD4 计数从 297 个细胞/μL 增加到 447 个细胞/μL(配对 t 检验,两者 P < 0.001)。在 HIV-1 阴性 (P < 0.001) 和 HIV-1 阳性患者 (P = 0.03) 中,CD4 计数增量与第 0 天的 CD4 计数呈负相关。成功治疗后,第45天CD4计数<200/μL的患者比例,HIV-1阴性的疟疾患者比例从9.6%下降到0%,HIV-1阳性疟疾患者的比例从28.7%下降到13.2%(两者P < 0.001)。在可检测到但大多无症状的寄生虫血症患者中,随访第 45 天时的 CD4 计数以及 HIV-1 感染的病毒载量与入组时观察到的相似。结论:在临床疟疾发作期间或之后,对绝对 CD4 计数的解释可能存在偏差。因此,在疟疾流行地区,在对 HIV-1 阳性个体的管理做出任何决定之前,应评估其疟疾状况。
Background:HIV-1-negative children with malaria have reversible lymphocyte and CD4 count decreases. We assessed the impact of malaria parasitemia on the absolute CD4 count in both HIV-1-infected and non-HIV-infected adults. Methods:In Ndola, Zambia, at the health-center level, we treated 327 nonpregnant adults for confirmed, uncomplicated, clinical malaria. We assessed HIV-1 status, CD4 count, and HIV-1 viral load (if HIV-1-infected) at enrollment and at 28 and 45 days after treatment. Results:After successful antimalarial treatment, the median CD4 count at day 28 of follow-up increased from 468 to 811 cells/μL in HIV-1-negative and from 297 to 447 cells/μL in HIV-1-positive patients (paired t test, P < 0.001 for both). CD4 count increment was inversely correlated with CD4 count at day 0 in both HIV-1-negative (P < 0.001) and HIV-1-positive patients (P = 0.03). After successful treatment, the proportion of patients with CD4 count <200/μL at day 45 decreased from 9.6% to 0% in HIV-1-negative and from 28.7% to 13.2% in HIV-1-positive malaria patients (P < 0.001 for both). In patients with detectable but mostly asymptomatic parasitemia, CD4 count and, if HIV-1-infected, viral load at day 45 of follow-up were similar to those observed at enrollment. Conclusion:Interpretation of absolute CD4 count might be biased during or just after a clinical malaria episode. Therefore, in malaria-endemic areas, before taking any decision on the management of HIV-1-positive individuals, their malaria status should be assessed.
