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 TBAfter TBI do not knowAsthma in TB 100% (17)82% (14)18% (3)0Number of asthma attacks93% (13)7% (1)0Severity of asthma attacks79% (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.
