Abstract

Background

MS patients are at increased risk for tuberculosis reactivation due to immunosuppressive therapies. Prevalence of latent tuberculosis in MS from our country is unknown.

Objective

To assess the prevalence and determinants of latent tuberculosis infection (LTBI) in MS patients from Colombia.

Methods

Multicentric, cross-sectional, retrospective study involving confirmed MS patients. LTBI was defined as a positive tuberculin skin test in asymptomatic patients with normal chest imaging. The prevalence (95 %CI) of LTBI was estimated and compared to the general prevalence with a one-sample proportion test. Determinants of LTBI were analysed using adjusted logistic regression.

Results

481 patients were included, with a mean age of 42 years and a mean MS duration of 10 years. The prevalence of LTBI was 6.24 % (95 %CI: 4.25–8.78), significantly lower than that of the general population (21.11 %; p < 0.001). Male sex (OR: 2.52; 95 %CI: 1.00–6.28, p = 0.046) was independently associated with LTBI.

Conclusion

LTBI is significantly less prevalent among our sample compared to the general population, and is associated with male sex.

来自一个流行国家的多发性硬化症患者潜伏结核感染的流行：一项横断面研究

背景：由于免疫抑制治疗，多发性硬化症患者结核病再激活的风险增加。我国多发性硬化症中潜伏性结核的患病率尚不清楚。目的了解哥伦比亚多发性硬化症（MS）患者潜伏性结核感染（LTBI）的流行情况及其影响因素。方法采用多中心、横断面、回顾性研究，纳入确诊的多发性硬化症患者。LTBI定义为无症状且胸部影像学正常的患者结核菌素皮肤试验阳性。估计LTBI的患病率（95% CI），并通过单样本比例检验与一般患病率进行比较。使用调整后的逻辑回归分析LTBI的决定因素。结果纳入481例患者，平均年龄42岁，MS平均病程10年。LTBI患病率为6.24% (95% CI: 4.25-8.78)，显著低于普通人群(21.11%；p & lt;0.001)。男性(OR: 2.52；95% CI: 1.00-6.28, p = 0.046)与LTBI独立相关。结论与一般人群相比，我们的样本中ltbi的患病率明显较低，并且与男性有关。

期刊介绍： Multiple Sclerosis is an area of ever expanding research and escalating publications. Multiple Sclerosis and Related Disorders is a wide ranging international journal supported by key researchers from all neuroscience domains that focus on MS and associated disease of the central nervous system. The primary aim of this new journal is the rapid publication of high quality original research in the field. Important secondary aims will be timely updates and editorials on important scientific and clinical care advances, controversies in the field, and invited opinion articles from current thought leaders on topical issues. One section of the journal will focus on teaching, written to enhance the practice of community and academic neurologists involved in the care of MS patients. Summaries of key articles written for a lay audience will be provided as an on-line resource. A team of four chief editors is supported by leading section editors who will commission and appraise original and review articles concerning: clinical neurology, neuroimaging, neuropathology, neuroepidemiology, therapeutics, genetics / transcriptomics, experimental models, neuroimmunology, biomarkers, neuropsychology, neurorehabilitation, measurement scales, teaching, neuroethics and lay communication.
