To determine whether systemic inflammation after initiation of HIV-antiretroviral therapy (ART) is associated with the development of diabetes.
We conducted a nested case-control study, comparing 55 previously ART-naive individuals who developed diabetes 48 weeks after ART initiation (case subjects) with 55 individuals who did not develop diabetes during a comparable follow-up (control subjects), matched on baseline BMI and race/ethnicity. Stored plasma samples at treatment initiation (week 0) and 1 year later (week 48) were assayed for levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and the soluble receptors of tumor necrosis factor-α (sTNFR1 and sTNFR2).
Case subjects were older than control subjects (median age 41 vs. 37 years, P = 0.001), but the groups were otherwise comparable. Median levels for all markers, except hs-CRP, decreased from week 0 to week 48. Subjects with higher levels of hs-CRP, sTNFR1, and sTNFR2 at 48 weeks had an increased odds of subsequent diabetes, after adjustment for baseline marker level, age, BMI at week 48, CD4 count at week 48 (< vs. >200 cells/mm(3)), and indinavir use (all P(trend) ≤ 0.05). After further adjustment for week 48 glucose, effects were attenuated and only sTNFR1 remained significant (odds ratio, highest quartile vs. lowest 23.2 [95% CI 1.28-423], P = 0.03).
Inflammatory markers 48 weeks after ART initiation were associated with increased risk of diabetes. These findings suggest that systemic inflammation may contribute to diabetes pathogenesis among HIV-infected patients.
确定 HIV 抗逆转录病毒治疗(ART)起始后全身炎症是否与糖尿病的发生有关。
我们进行了一项嵌套病例对照研究,比较了 55 例在 ART 起始后 48 周发生糖尿病的初治患者(病例组)和 55 例在相当随访期间未发生糖尿病的患者(对照组),匹配了基线 BMI 和种族/民族。在治疗起始(第 0 周)和 1 年后(第 48 周)储存的血浆样本中测定高敏 C 反应蛋白(hs-CRP)、白细胞介素-6(IL-6)和肿瘤坏死因子-α的可溶性受体(sTNFR1 和 sTNFR2)水平。
病例组比对照组年龄更大(中位数年龄分别为 41 岁和 37 岁,P=0.001),但两组在其他方面无差异。除 hs-CRP 外,所有标志物的中位数水平从第 0 周降至第 48 周。在第 48 周时 hs-CRP、sTNFR1 和 sTNFR2 水平较高的患者,在调整了基线标志物水平、年龄、第 48 周 BMI、第 48 周 CD4 计数(<200 细胞/mm3 和>200 细胞/mm3)和使用沙奎那韦(所有 P(趋势)≤0.05)后,其随后发生糖尿病的可能性增加。在进一步调整第 48 周血糖后,作用减弱,只有 sTNFR1 仍具有显著性(最高四分位数与最低四分位的比值,最高四分位与最低四分位的比值 23.2[95%CI 1.28-423],P=0.03)。
ART 起始后 48 周时的炎症标志物与糖尿病风险增加相关。这些发现提示全身炎症可能在 HIV 感染患者的糖尿病发病机制中起作用。
