Abstract
Introduction: In clinical practice, it was observed that TB patients rarely develop bronchial asthma.
Objectives: To compare asthma prevalence in TB and non-TB patients.
To compare the number of asthma attacks and severity before and after TB infection.
Design and settings: The study was performed in 2013 on 322 adult TB Sudanese patients ( 194 from Khartoum and 128 from Kosti ). Subjects had completed a questionnaire containing data about incidence, number of attacks and severity of asthma.
The prevalence of asthma in TB patients was compared to reference asthma prevalence in non-TB subjects. The number of asthma attacks and severity of symptoms before and after development of TB were compared.
Results: In Khartoum: The prevalence of asthma in TB patients was 5% compared to 10% in non-TB patients (1). 80% of asthmatic TB patients had developed asthma before TB. 88% of asthmatic TB patients had reported an increase in the umber of asthma attacks before TB and 75% had reported an increase in asthma severity before they developed TB.
In Kosti: The prevalence of asthma in TB patients was 5% compared to 6.4% in non-TB patients (1). 86% of asthmatic TB patients had developed asthma before TB. All asthmatic TB patients had reported an increase in number of asthma attacks before TB and 83% had reported an increase in asthma severity before they developed TB
Before TB | After TB | I do not know | |
Asthma in TB 100% (17) | 82% (14) | 18% (3) | 0 |
Number of asthma attacks | 93% (13) | 7% (1) | 0 |
Severity of asthma attacks | 79% (11) | 14% (2) | 7% (1) |
Asthmatic TB patients ( Khartoum and Kosti)
Conclusion: It had been found that TB infection decreased asthma prevalence, number of attacks and severity of symptoms.
