“…[8][9][10][11] It has been shown that EBTB may be misdiagnosed as bronchial asthma as it causes wheezing. 12,13 Approximately 24% of the studied patients who had this sign had been mistakenly treated for bronchial asthma for long periods before diagnosis. Radiological workup in 15% of the patients showed thoracic mass lesions in their CT scans, but no invasive procedures were performed until active lung tuberculosis was ruled out.…”

“…Exercise challenge and histamine challenges identify different pathways in the airways (31). Although tuberculosis is prevalent both in the Transkei and in Cape Town in the Xhosa population, individuals with endobronchial tuberculosis do not have significantly increased BHR (32).…”

Twenty years ago, the prevalence of atopic sensitization and bronchial hyper‐responsiveness (BHR) in Xhosa children in a rural location in South Africa was very low. The aim of this study was to document the current prevalence of these two indices by comparing traditional rural Xhosa children, recently urbanized Xhosa children and established city white children, and to consider factors that may account for the observed increase in all of these groups. One thousand four hundred and fifty‐seven school children aged 10–14 years from the rural Transkei, from a recently urbanized peri‐urban area and from urban Cape Town areas were studied using a questionnaire. Four hundred and eighteen children had histamine challenges, and 492 tests for atopy were also conducted. As determined by bronchial challenge with histamine, 17% of rural and 34.4% of recently urbanized Xhosa children had increased BHR, a marked increase from the 0.03% and 3.17% prevalence of increased BHR previously found using the exercise challenge. The prevalence of increased BHR in white urban children was 33%. Sensitization to one or more aero‐allergens, as indicated by CAP RAST tests, was present in 36.6% of the rural Xhosa children with normal BHR and in 62.5% of those with increased BHR, a striking increase from that of previous studies. Atopic sensitization to one or more aero‐allergens, as indicated by a skin prick test (SPT), was found in 42.3% of the recently urbanized Xhosa children and 45% of urbanized white children. We have also documented sensitization to house dust mites in the rural Xhosa children for the first time. Passive cigarette smoking was not identified as a risk factor for increased BHR or atopy. Wood smoke in the indoor environment did not play a role in the rural Xhosa children's BHR. Ascaris infection does not appear to play any modifying role in the development of increased BHR in the rural or urban children. We have found that increases in BHR in the rural and recently urbanized Xhosa children develop independently of increases in atopy. Our results challenge the ‘hygiene’ hypothesis as a complete explanation for the recent dramatic worldwide increases in allergic diseases.

“…The bronchostenosis is mainly determined by the extent of disease progression and closely related to the formation of granulation tissue [7,8]. Once fibrostenosis already develops or extensive granulation tissue appears, remarkable bronchostenosis is inevitable despite of efficacious anti-tuberculosis chemotherapy [9-11]. The incidence rate of broncho stenosis may reach up to 68% in initial 4 to 6 months of the disease and rises further with the course of disease elongating [12].…”

BackgroundEndobronchial tuberculosis (EBTB) is a special form of pulmonary tuberculosis. In spite of much progress in the diagnosis of this disease in past years, delayed or mistaken diagnosis is still commonly seen.ObjectiveThe aim of this study is to try to find out some useful clues for the diagnosis of EBTB, especially the early diagnosis.MethodsThe medical records of patients with EBTB were analyzed retrospectively. Results: The male-to-female ratio was 1:2.2 out of 22 patients. Patients aged below 60-years-old constituted 72.7% of the cases. 22.7% of these patients were smokers. The male-to-female ratio of smokers was 4:1. 68.2% of these patients tested all showed negative result for the HIV test. The frequent complaints were cough, sputum, shortness of breath and fever, and antibiotic treatments were usually inefficacious. Multiple lobes lesion, exudative shadow and atelectasis were the frequent radiological findings. Acid-fast bacilli staining for sputum smear was positive in only 13.6% of these patients. Tuberculin skin test was positive in 59.1% of these patients. Granular lesion was the most common bronchoscopic appearance in these patients. Histological changes showed distinctive tuberculose lesion in 72.2% of 18 patients undergoing bronchoscopic biopsy.ConclusionThe diagnosis of EBTB is easily delayed or mistaken because of nonspecific clinical manifestations and the low incidence of positive acid-fast bacilli staining. A high index of awareness of this disease is required for diagnosis. Bronchoscopy should be performed as soon as possible in suspected patients, especially when patients present positive tuberculin skin test or no response to antibiotic treatments.
