Clinical analysis of foreign-born patients with tuberculosis found in Malaysia.

In this retrospective study, we investigated 263 foreign patients who were diagnosed as having tuberculosis at the National Tuberculosis Center (NTBC) from January 2001 to December 2002. The age range was 14-72 years, with a mean of 33.3 +/- 9.95 years. The study subjects were predominantly males (60%) and females comprised 40%, where the greater impact of tuberculosis was observed in the young and active ones (up to 34 years of age), than middle-age (up to 54). A significantly higher percentage of these patients were from the Southeast Asian countries (87%) and particularly occurred in single male (47.5%) and married female (71.4%) patients (p<0.05). We also found that tuberculosis was significantly higher in female (50.5%) and male (64%) with smoking laborers (p<0.05). Fever (70%), cough (90.5%) and BCG vaccination status showed a significantly higher percentage in male patients (p<0.05), whereas lymphadenopathy (22%) was found in a significantly higher percentage in females (p<0.05). Overall, pulmonary disease (94.3%) occurred more commonly in males and the pleura (3.2%) was the most common site of disseminated tuberculosis. By contrast, the lymph node (11.4%) and miliary (4.8%) forms were the more common extrapulmonary tuberculosis in females. More males had higher percentage of treatment completed at > or = 6 (38%) and > or = 9 (13.3%) months in pulmonary tuberculosis, whilst, more females showed higher percentage of treatment completed (8.7%) in extrapulmonary tuberculosis. Surprisingly, more women showed non-compliance to the anti-tubercular therapy than their counterpart in this study.

Tuberculosis in HIV/AIDS patients: a Malaysian experience.

This retrospective study was conducted at the National Tuberculosis Center (NTBC) where 252 HIV-positive patients coexisting with tuberculosis (TB/HIV) were examined. We found that patients with pulmonary (PTB) and extrapulmonary tuberculosis (EPT) had similar mean age. A higher sex ratio between male to female (10.7:1) was observed in patients with PTB. The other characteristics of patients with pulmonary and extrapulmonary tuberculosis were not statistically different from each other. Cough (88%) and hemoptysis were the most common presenting symptoms, significantly related to patients with PTB. Lymphadenopathy (33.5%) was the most common sign in patients with EPT. The majority of patients with pulmonary and extrapulmonary tuberculosis had CD4 cell counts of less than 200 cells/mm3 (range 0-1,179 with a median of 57 cells/mm3). Lung (89%) and miliary (55.6%) forms were the most frequent disease locations in patients with PTB and EPT, respectively. A higher percentage of patients with PTB (42%) were treated successfully with short-course (6 months) therapy, whereas in patients with EPT (43%) needed a longer period (9 months) for successful treatment. Of the patients who defaulted treatment, a higher proportion (87%) had PTB. No MDR-TB or relapse cases were found in this study.

Tuberculosis in diabetic patients: a clinical perspective.

This retrospective and descriptive study was a report on the clinical situation of tuberculosis in diabetic patients, with 1,651 patients recruited. The mean age of TBDM patients was significantly higher than that of non-diabetic patients (p<0.05). Moreover, TBDM patients had a higher ratio of male to female than the other group. The significant proportion of TB appeared to increase steadily with age in diabetic patients compared to non-diabetic ones (p<0.05). However, they showed similarities in terms of sex, race, marital status, present address, and occupation. A higher percentage of pulmonary tuberculosis (91.4%) was shown in the TBDM group. We found that both groups had no differences in the radiological findings, with opacity or cavity of the upper lobe involvement being 89% and 91% in TBDM and non-diabetic groups, respectively. TBDM patients were shown to have more treatment success (33.3%), particularly the pulmonary type of tuberculosis in the longer duration ( 9 months). Further findings demonstrated that a lower proportion of the TBDM group defaulted in their treatment (19.8%) and experienced resistance to anti-tubercular therapy (1.4%) compared to non-diabetics.

Extrapulmonary tuberculosis in Peninsular Malaysia: retrospective study of 195 cases.

During a 2-year retrospective study, 195 non-HIV-infected patients with extrapulmonary tuberculosis (EPT) were diagnosed at the National Tuberculosis Center, Kuala Lumpur, representing 10% of all patients with tuberculosis. Their mean age was 39 (+/- SD) 14 years old (range 14-81). The largest age group was 25-34 years, while 78.5% were less than 50 years of age. The subjects were mainly female (50.3%), Malay (49.2%), married (61.5%), resided in Kuala Lumpur (51.0%), and were unemployed (50.3%). Regarding risk factors, they were smokers and/or alcohol users (21.0%), and injecting drug users (IDUs) (5.1%); they also had history of tuberculosis (3.6%) and contact with TB patients (9.2%). Lymphadenopathy was the most common sign (45.6%) shown in the medical records. 42% of x-ray findings (chest, spine, and hip) showed signs consistent with tuberculosis, while histopathology was the most useful diagnostic tool (52.3%) and lymph node was the most frequent specimen used (35.0%) in this study. The three main sites of involvement were lymph nodes (42.6%), miliary and disseminated (19.5%), and pleura (12.8%). The outcome of this study showed 72.8% of these patients had completed treatment for at least 6 months, whilst, only 4.6% of patients were still undergoing treatment, and unfortunately, 22.6% of them showed non-adherence to anti-tubercular therapy at a duration of less than 6 months. However, no MDR-TB or death cases were reported or registered in this study.

Notification of occupational and work-related diseases and poisonings in Malaysia, 1997-1998.

In 1997, the Ministry of Health Malaysia introduced a surveillance programme for occupational and work-related diseases including poisonings for cases seen in government health facilities. Between June 1997 and November 1998, there were 36 cases of respiratory disease and 95 cases of poisoning by chemicals and pesticides notified while skin diseases were 108 cases. Respiratory diseases reported were predominantly occupational asthma (25%), pneumoconiosis (17%) and infections (39%). The commonest reported skin disease was contact dermatitis (87%). The commonest causes of occupational poisonings were paraquat (19%), organo-phosphates (16%), agro-chemicals excluding pesticides (15%) and gases (10%). The number of cases reported is still relatively few compared to data from other countries, suggesting that there is still considerable under reporting.

Fibreoptic bronchoscopy in the diagnosis of pulmonary tuberculosis--a Malaysian experience.

We report our experience on the use of fibreoptic bronchoscopy in the diagnosis of pulmonary tuberculosis. The case records of 1,274 patients who underwent fibreoptic bronchoscopy at the National Tuberculosis Centre, Kuala Lumpur, Malaysia during a three-year period were reviewed. In 120 of them the final diagnosis was tuberculosis. Bronchoscopy confirmed the diagnosis in 37 patients (30.8%). This was achieved by bronchial aspiration for culture in 26 patients (70.3%) and bronchial biopsy for histopathology in 11 patients (29.7%). It was the exclusive method of confirmation in 16 patients (13.3%). Sputum culture was positive in 62 patients (51.7%) including 41 patients (34.2%) in whom bronchoscopy was unhelpful. Six patients had diagnosis confirmed by other means while in 36 others (30%) it was based on clinical features and supportive basic investigations. There were no complications noted. We conclude that while sputum examination remains the mainstay for diagnosing pulmonary tuberculosis, fibreoptic bronchoscopy serves as a safe and useful adjunct.

A study of primary drug resistance in pulmonary tuberculosis in west Malaysia 1984-1987.

Eight hundred and fifty-six strains of Mycobacterium tuberculosis from previously untreated patients with pulmonary tuberculosis from various states in West Malaysia were studied during the period 1984 to 1987. All the strains were tested for in vitro susceptibility to the anti-tuberculosis drugs isoniazid (INH), streptomycin (SM), rifampicin (RMP) and ethambutol (ETB). One hundred and twenty-one of the isolates (14.18%) were resistant to 1 drug while 17 (1.97%) were resistant to 2 drugs. No strain was found to be resistant to more than 2 drugs. The prevalence of primary resistance to INH was 4.20%, SM was 7.59%, RMP was 0.95% and ETB was 1.44%. In 1.86% of isolates, resistance was noted to both INH and SM, while 0.11% were resistant to both RMP and ETB. There was no significant difference in distribution of resistant bacilli between the sexes (p > 0.01).

Spinal tuberculosis: a five-year review of cases at the National Tuberculosis Centre.

We reviewed 31 cases (19 males and 12 females) of spinal tuberculosis seen at the National Tuberculosis Centre from 1985 to 1989. The mean age was 35.4 years. The predominant clinical feature was backache (90.3%), while neurological features were found in 30.9%. An elevated erythrocyte sedimentation rate (in 80.0%) and a positive Mantoux test (in 70.9%) served as useful investigations. Spinal x-ray was abnormal in all cases, the lumbar spine being most commonly involved. Bacteriological or histopathological confirmation was obtained in only 29.0% of cases. The mainstay of treatment was anti-tuberculous chemotherapy with surgery being performed in 41.9% of patients.
