To the Editor—In our opinion, the extent to which dysglycemia is causally associated with tuberculosis (TB) remains unanswered. Ugarte-Gil and colleagues, with no control group, cannot answer that question [1]. We note that the prevalence of diabetes in, for example, their South African TB patients is not dissimilar to that reported in the general population of South Africans aged >30 years [2]. In fairness, their TB cohort is at the lower end of this age distribution.

肺结核和血糖异常

致编辑-我们认为，血糖异常与结核病（TB）因果关系的程度尚无定论。没有对照组的Ugarte-Gil及其同事无法回答该问题[1]。我们注意到，例如，其南非结核病患者中的糖尿病患病率与30岁以上的南非普通人群中报道的相近[2]。公平地说，他们的结核病队列处于这一年龄分布的低端。
