The utility of the adenosine deaminase (ADA) assay in the diagnosis of patients with pleural tuberculosis (TB) and human immunodeficiency virus (HIV) infection is controversial. Forty-eight HIV positive patients with pleural effusion were evaluated; ADA assay was obtained in forty-three of them. Twenty-five patients presented diagnosis of TB. Patients with diagnosis of TB showed a median value of ADA of 70 IU/L (interquartile range (IQR) 41⁻89) and the non-TB group a median of 27.5 IU/L (IQR 13.5⁻52). Patients with diagnosis of TB had a median cluster of differentiation 4 (CD4) count of 174 (IQR 86⁻274) and the non-TB group had a median of 134 (IQR 71⁻371). Receiver operating characteristic curve was performed with an area under the curve of 0.79. The best cut-off obtained was 35 IU/L with a sensibility of 80% and a specificity of 66%. There was no correlation between CD4 lymphocytes count and the value of ADA in the TB patient group.
腺苷脱氨酶（ADA）检测在诊断合并胸膜结核（TB）和人类免疫缺陷病毒（HIV）感染患者中的作用存在争议。对48例HIV阳性且伴有胸腔积液的患者进行了评估；其中43例进行了ADA检测。25例患者被诊断为TB。诊断为TB的患者ADA中位数为70 IU/L（四分位间距（IQR）41⁻89），非TB组中位数为27.5 IU/L（IQR 13.5⁻52）。诊断为TB的患者分化簇4（CD4）计数中位数为174（IQR 86⁻274），非TB组中位数为134（IQR 71⁻371）。绘制了受试者工作特征曲线，曲线下面积为0.79。得到的最佳截断值为35 IU/L，敏感性为80%，特异性为66%。TB患者组中CD4淋巴细胞计数与ADA值之间无相关性。
