Tuberculosis (TB) remains a major global public health challenge, with 10 million incident cases estimated in 2019. Historically, national TB programmes and international TB policy frameworks have focused on the need to identify active TB cases, improve access to care and ensure treatment completion, in order to achieve microbiological cure and improve disease survival. However, in recent years as TB survival has slowly improved, there has been a growing focus on residual post-TB morbidity, with calls for TB programmes to consider the long-term physical, psychosocial and socioeconomic well-being of TB survivors even after TB treatment completion.1 Residual lung damage after pulmonary TB disease—or post-TB lung disease—is a particular concern in TB endemic settings. For patients with TB in low-income and middle-income countries (LMICs) residual respiratory symptoms may be highly stigmatising, interfere with work and livelihoods, and lead to costly health seeking after TB treatment completion. For healthcare providers the lack of access to respiratory diagnostics, treatment guidelines and established care pathways make patients with post-TB lung disease particularly challenging to manage.
The study by Kamenar et al2 highlights the relationship between previous TB and residual chronic obstructive pulmonary disease (COPD) in LMICs. This paper is a pooled analysis of five population-based studies in LMICs, which include data from 12 396 adults from thirteen resource-poor settings in six countries, of whom 332 (2.7%) reported a history of previous TB disease. It examines the relationship between COPD—defined as a post-bronchodilator forced expiratory volume in …
