Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

Long Acting Muscarinic Antagonists (LAMA) such as tiotropium and glycopyrronium are used in the management of COPD1. They have been shown to improve lung function, quality of life and exercise tolerance. They have also been associated with reduced COPD-related exacerbations, associated hospitalisati...ons and duration of hospital stay. Both the South African Thoracic Society (SATS) and Global Initiative for Chronic Obstructive Lung Disease (GOLD), guidelines recommend the use of long acting anticholinergic drugs (or long acting beta agonists) in moderate to very severe disease as defined by lung function (FEV1). The most up to date guideline, utilizing the GRADE methodology (European Respiratory Society guidelines of 2017), confirms their superiority over long acting β agonists (LABA) as monotherapy for COPD in that LAMA's have demonstrated greater efficacy in terms of exacerbation reduction, with similar safety profile.2 These recommnedations are supported by published peer-reviewed
evidence including individual papers and Cochrane reviews.

This document serves as an update to “Out of the Dark”, a report published by MSF in October 2011, highlighting the need to prioritise the long-neglected area of paediatric tuberculosis (TB). This update will outline the key improvements and setbacks—the ‘highlights’ and ‘...lowlights’—that have occurred over the last year.
