Extra- pulmonary tuberculosis ( EPTB) contributes to the burden of Tuberculosis (TB) especially in developing countries. Despite this fact, information on the prevalence of EPTB is scarce. The aim of this study is to determine the five-year prevalence of EPTB among patients diagnosed with tuberculosis (TB) that attended and received treatment for TB at directly observed treatment short course (DOTS) clinic of Abubakar Tafawa Balewa University Teaching Hospital (ATBUTH), Bauchi, North-eastern Nigeria.
This is a retrospective review of all patients' records diagnosed with TB that attended and received treatment at the TB DOTS clinic of ATBUTH, Bauchi from January, 2017 to December, 2021. Extracted data was analyzed using IBM SPSS version 23.0 software.
There were 676 patients comprising of 389 (57.5%) males and 287 (42.5%) females and out of these, 208 had EPTB. The estimated five-year prevalence of EPTB in the studied cases was 30.8%. Tuberculosis of the spine was the predominant form of EPTB in this study with 117 (56.3%) cases. This was followed by TB Lymph nodes 40 (19.2%), TB Abdomen 36 (17.3%), TB Pleura 6 (2.9%), TB Pericardium 3 (1.4%), 2 (1.0%) each of TB Breast and CNS, and 1 (0.5%) each of TB Testicle and Upper arm. Seventy-eight (11.5%) patients were HIV positive, 549 (81.2%) were HIV-negative and the HIV status of 49 (7.2%) patients was unknown.
The study showed prevalence of EPTB is still high as reported in some literature. Tuberculosis of spine was the commonest form of EPTB. These findings underscore the need for continued screening of EPTB to reduce the burden of TB in resource-poor countries.
肺外结核（EPTB）是结核病（TB）负担的重要组成部分，尤其在发展中国家。尽管如此，关于 EPTB 患病率的信息仍然有限。本研究旨在确定在直接观察短期疗程（DOTS）诊所接受结核病（TB）治疗的患者中，EPTB 的五年患病率。
这是对 2017 年 1 月至 2021 年 12 月期间在巴州阿卜杜勒·塔法瓦·巴莱瓦大学教学医院（ATBUTH）DOTS 诊所就诊并接受治疗的所有 TB 患者记录的回顾性研究。使用 IBM SPSS 版本 23.0 软件分析提取的数据。
共有 676 名患者，其中 389 名（57.5%）为男性，287 名（42.5%）为女性，其中 208 名患有 EPTB。在研究病例中，EPTB 的五年患病率估计为 30.8%。脊柱结核是本研究中最主要的 EPTB 形式，有 117 例（56.3%）。其次是淋巴结结核 40 例（19.2%）、腹部结核 36 例（17.3%）、胸膜结核 6 例（2.9%）、心包结核 3 例（1.4%）、乳房和中枢神经系统结核各 2 例（1.0%），睾丸和上臂结核各 1 例（0.5%）。78 名（11.5%）患者 HIV 阳性，549 名（81.2%）HIV 阴性，49 名（7.2%）患者 HIV 状态未知。
研究表明，EPTB 的患病率仍然很高，正如一些文献报道的那样。脊柱结核是最常见的 EPTB 形式。这些发现强调需要继续筛查 EPTB，以减少资源匮乏国家的结核病负担。
