    The objectives in this epidemiology review are to measure and report the extent of morbidity and mortality due to tuberculosis (TB), the proportion of new sputum smear positive cases in districts and the status of cohort analysis as of 1999. As for leprosy, the main objective is to determine morbidity and the treatment outcomes of Multiple Drug Therapy (MDT). Based on the results obtained, a comprehensive action plan for prevention, control and monitoring of tuberculosis and leprosy cases and patients is being produced and implemented throughout the state. The analysis concentrated on patients diagnosed at all out-patient units and admitted in all of the state's hospitals. The patient particulars were recorded using a standardized format based on TB and Leprosy Health Management Information System (TB HMIS). TB was the second highest by notification of communicable diseases in Malaysia in 2001. 29% or about one-third of the national TB cases are from Sabah. However, it has been noted that there was an average decline of 2.6% in annual notification since 10 years ago to date. There was also a reduction of 11.4% in 2001 as compared to annual notification in 2000. Immigrants contribute more than 24% in detection of new cases since 1990. Treatment success rate in term of completion of treatment to date is 82%. Mortality rate has steadily declined from 14 deaths to 7 deaths per 100,000 population. Leprosy in Sabah also contributes to 30% of the yearly total caseload of Malaysia and has the highest notification rate of 2 per every 100,000 population as compared to other states. The average registered leprosy cases over the past 5 years are 239 cases and the prevalence rate is 0.7/10,000 population. The state has successfully achieved its goal to decrease leprosy as per the World Health Organization (WHO) goal of yearly overall prevalence rate of less than 1 case for every 10,000 population. However, the districts of Kudat, Tawau, Lahad Datu, Kota Kinabalu and Semporna are still within the prevalence rate of more than one per 10,000 population. This review highlights some interesting findings which can be incorporated into the State and Districts action plans and strategies. It is also noted that in order to translate National Plans and Strategies into effective action at the community level, health workers need relevant up-to-date knowledge of the pattern of health and disease, and of their determinants, in each district. The Sabah Health Department continues to organize and support programs related to management and control of tuberculosis and leprosy to progressively reduce the incidence of these diseases in the community by breaking the chain of transmission of Mycobacterium tuberculosis and M. leprae, respectively.

    In the early 1940s and 1950s, tuberculosis (TB) was the number one cause of death in Malaysia. Patients with TB were admitted to the many sanatoria we had in various parts of the country and were often managed by surgical means. TB chemotherapy became available only in the late 1950s. At this time, TB was already a major cause of morbidity and mortality. Realizing its seriousness, the Malaysian government launched its National TB Control Programme (NTP) in 1961. At that time, the recommended treatment for TB was a combination of three drugs, namely, streptomycin, isoniazid and paraaminosalicylic acid (PAS) given for 2 months followed by isoniazid and PAS given for 12 months. Generally the treatment used to last for 1-2 years. The National TB Centre in Kuala Lumpur functioned as the headquarters of the NTP, and the state general hospitals with their chest clinics functioned as the state directorates. From the operational point of view, every state has a state TB directorate which is known as the State TB Managerial Team (Fig. 1). This team is responsible for the implementation of the activities of the NTP at the state and district levels. Ever since 1995, the national TB directorate has been shifted to the Public Health Division of the Ministry of Health (MOH) and is now under the Director of Disease Control (Fig. 2). The National TB Centre has now been renamed as The Institute of Respiratory Medicine. Over the years from being the number one cause of death, TB has dropped to being below number 10 (Fig. 3).

    Tuberculosis (TB) remains a major cause of morbidity and mortality worldwide and the main cause of death in correctional facilities in middle- and low-income countries. Due to the closed environment and the concentration of individuals with TB-related risk factors, effective measures are required to control TB in such settings. Isoniazid preventive therapy (IPT) represents an effective and cost-effective measure. Despite international recommendations that IPT be integral to TB control, it is seldom deployed. A systematic review of interventions used to assess IPT initiation and completion in correctional facilities was conducted using published studies from two biomedical databases and relevant keywords. Additional references were reviewed, resulting in 18 eligible studies. Most (72%) studies were conducted in the United States and in jail settings (60%), with the main objective of improving completion rates inside the facility or after release. Studies that provided data about initiation and completion rates showed poor success in correctional facilities. Adverse consequences and treatment interruption ranged from 1% to 55% (median 5%) in reported studies; hepatotoxicity was the most prevalent adverse reaction. Despite its accelerating effect on the development of active TB, information on human immunodeficiency virus (HIV) status was provided in only half of the studies. Among the four studies where IPT effectiveness was assessed, the results mirror those described in community settings. Future studies require thorough assessments of IPT initiation and completion rates and adverse effects, particularly in low- and middle-income countries and where comorbid viral hepatitis may contribute significantly to outcomes, and in settings where TB and HIV are more endemic.

    BACKGROUND: Serial testing for tuberculosis (TB) exposure has been advocated among health care workers (HCWs) at risk of nosocomial infection.
    OBJECTIVE: To determine the incidence and factors associated with TB infection among selected HCWs in Malaysia and to determine interferon-gamma response in serial testing.
    DESIGN: A cohort of 769 HCWs were retested after 1 year using QuantiFERON®-TB Gold In-Tube. Incidence of TB infection was determined among HCWs who previously tested negative. Conversion and reversion rates using several definitions were explored.
    RESULTS: Incidence of TB infection was 9.9 per 100 workers per year (95%CI 7.9-12.3). Working in the Emergency Department (ED; RR 2.18, 95%CI 1.07-4.43) was significantly associated with risk of TB infection. Reversion and conversion occurred frequently, with 46.7% reversion among HCWs with baseline interferon-gamma (IFN-γ) levels of 0.35-0.70 international units (IU)/ml, and 23.8% conversion among HCWs with baseline IFN-γ levels of 0.20-0.34 IU/ml.
    CONCLUSIONS: TB infection control measures need to be strengthened, particularly in the ED, as the incidence of TB was high. Conversion and reversion rates in serial testing were high, and further studies are needed to facilitate its interpretation.

    SETTING: An urban university teaching hospital.
    OBJECTIVES: To determine patients' attitudes to tuberculosis and their knowledge of the disease, and factors associated with treatment compliance.
    DESIGN: All adult patients commenced on treatment for tuberculosis from September 1994 to February 1996 were interviewed on initiation of treatment. To assess patient compliance with treatment, hospital clinical records were reviewed retrospectively.
    RESULTS: A total of 135 patients with a mean age (±SD) of 41.9 (±17.4) years (range 15–84 years) were interviewed. The patients had limited understanding and knowledge about tuberculosis. There was a negative correlation between patient age and tuberculosis knowledge score (r = −0.18, P = 0.038). Patients with tertiary education had better knowledge than the others. Of 118 patients who were followed-up in our chest clinic, 80 (67.8%) completed the prescribed treatment. Compliance with treatment and follow-up was not affected by age, sex, ethnic group, educational level, occupation, extent of knowledge, tuberculosis symptoms, hospitalisation for tuberculosis or duration of the prescribed treatment regimen. There was a trend toward poorer compliance among patients who equated disappearance of tuberculosis symptoms with cure of the disease.
    CONCLUSIONS: Malaysian patients with newly diagnosed tuberculosis attending a university teaching hospital had misconceptions and limited knowledge about the disease and its treatment. Educational background was an important determinant of a patient's level of knowledge about tuberculosis. Compliance was not affected by patient characteristics. Adequate counselling and education of patients and close relatives on tuberculosis and the necessity for prolonged treatment may help to improve treatment compliance.

    BACKGROUND: Drug resistance in general, and multidrug-resistant tuberculosis (MDR-TB) in particular, threatens global tuberculosis (TB) control efforts. Population-based estimates of drug resistance are needed to develop strategies for controlling drug-resistant TB in Pakistan.

    OBJECTIVE: To obtain population-based data on Mycobacterium tuberculosis drug resistance in Pakistan.

    METHODS: To obtain drug resistance data, we conducted a population-based study of TB cases in all provinces of Pakistan. We performed culture and drug susceptibility testing on M. tuberculosis isolates from patients with a prior history of anti-tuberculosis treatment (retreatment cases) from all over the country.

    RESULTS: Of 544 isolates from previously treated cases, 289 (53.1%) were susceptible to all first-line drugs, 255 (46.9%) were resistant to at least one anti-tuberculosis drug and 132 (24.3%) were MDR-TB. Among MDR-TB isolates, 47.0% were ofloxacin (OFX) resistant. Extensively drug-resistant TB was found in two (0.4%) isolates.

    CONCLUSION: Prevalence of drug resistance in retreatment isolates was high. The alarmingly high prevalence of OFX resistance among MDR-TB isolates may threaten the success of efforts to control and treat MDR-TB.

    A total of 136 patients, 67 HIV, 69 diabetes mellitus (DM) with or without (+/-) end-stage renal disease (ESRD), were registered for tuberculosis treatment at the National Tuberculosis Center (NTBC) from May to December, 2003. Ages ranged from 21-78 years (median 57.7 years) in TB/DM patients, and 21-62 (mean 37.6 +/- 8.3 years) in TB/HIV patients. TB was significantly found in younger and single HIV patients, but in older and married DM patients (p<0.05). Male patients in both groups were strongly associated with TB, while females more commonly had TB with DM (p<0.05). The majority of these patients were Malays, unemployed, and resided in Kuala Lumpur territory; however, no statistically significant difference was found between the 2 groups. Smoking, IVDUs and hepatitis C virus (HCV) infection were more significantly found in TB/HIV patients and further analysis showed that pulmonary TB was strongly associated with HCV infection in these patients (p<0.05). Pulmonary TB (62; 89.9%) was the most common type found in both groups and was a markedly more common disease location in TB/DM patients, while extrapulmonary TB (21; 31.3%) and miliary TB (14; 21%) were significantly higher in TB/HIV patients. Cough with or without sputum, fever and loss of appetite and/or weight were common clinical presentations in both groups. Nevertheless, fever (54; 80.6%) and lymphadenopathy (17; 25.4%) were significantly related to TB/HIV patients (p<0.05). Interestingly, the presence of BCG vaccination and positive tuberculin skin test were stronger in TB/HIV (27; 40.3%) and TB/DM (20; 29%) patients, respectively (p<0.05). Overall, regular 6-, 9- and 12-months' anti-tubercular therapy (ATT) were routine practice, and EHRZ+B6 was the most common regimen used. The highest percentage of patients with treatment success were in both groups with 6 months' ATT; however, a significantly higher percentage was found in TB/DM (24; 34.8%) than TB/HIV (13; 19.4%) (p<0.05). A success rate of 15 (21.7%) was noted for TB/DM patients with 9 months' ATT, which was similar to both groups with the 12-month regimen. A higher percentage failure rate (lost to follow-up) was seen in TB/HIV (19; 28.4%) patients. Nine patients were reported to have anti-tubercular-drug side-effects, such as drug-induced hepatitis, blurred vision, and skin rash. No cases of drug resistance or death were notified among these patients.

    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.

    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.

    Tuberculosis (TB) has made a comeback. It has become a resurgent public health problem in developing countries in the tropics and is the leading cause of death from any single infectious agent. Non-compliance to anti-tuberculosis treatment is the most serious problem in TB control. A cross-sectional study was conducted to investigate the determinants of poor compliance with anti-tuberculosis treatment among tuberculosis patients in Kota Bharu, Kelantan, Malaysia in 1999. A total of 390 patients were included in the study of which 130 were tuberculosis patients who defaulted treatment and 260 were those compliant to treatment. Data collection was done by interviewing the patients and collecting clinical and laboratory data from their medical records. Using multiple logistic regression analysis, patients who were not on direct observed therapy (DOT) lived distant to the health facility, were non-intravenous drug users (IVDU) and were HIV positive had statistically significant higher odds of being non-compliant. Patients should be given treatment under direct supervision with special attention to IVDU and HIV positive groups. Anti-TB treatment should be accessible to patients at the nearest health center from their residence. Interventions with health education programs emphasizing the benefits of treatment compliance should be implemented by further large-scale multicentered studies.

    The human immunodeficiency virus (HIV) epidemic has had a profound influence on the epidemiology of tuberculosis (TB). The potential for HIV-associated TB cases to transmit M. tuberculosis and to produce a secondary increase in TB morbidity is unknown. A cross-sectional study was carried out to compare the prevalence of M. tuberculosis infection among the household contacts of HIV-positive and HIV-negative pulmonary tuberculosis (PTB) patients. Records of tuberculin (Mantoux) tests administered during routine contact investigations at the Chest Clinic, Hospital Kota Bharu, from 1999 to 2000 were reviewed. The HIV status of the patients was based on the results of ELISA tests while information on household contacts was gathered during visits to their houses. Ninety-four contacts of 39 HIV-negative patients and 44 contacts of 17 cases of HIV-positive patients were included in this preliminary study. 30% (12/40) of the contacts of HIV-positive PTB had a positive tuberculin compared with 52.8% (47/ 94) of the contacts of HIV-negative patients [OR = 0.41, 95% Confidence interval (CI) 0.17 - 0.97; p = 0.016]. The difference was still significant after performing multivariate logistic regression analysis to adjust for variables associated with infectiousness of TB (adjusted OR = 0.24, 95% CI 0.07 - 0.87; p = 0.03). This study has shown that HIV-infected PTB patients are less infectious to their contacts than HIV-negative patients. The presence of MV in the community may not necessitate a change of the current policy of the management of contacts.

    A total of 290 HIV/AIDS patients were recruited into this retrospective study, which was carried out at the National Tuberculosis Center (NTBC), Kuala Lumpur. The age range was 18 to 75 years with a mean age of 36.10 (SD +/- 7.44) years. Males outnumbered females by a ratio of 31:1. In this study, the majority of patients were male (96.9%), Malay (47.2%), single (66.9%), unemployed (81%), and smoked (61.4%). The main risk marker identified was injecting drug use (74.5%). The most common clinical manifestations were cough, fever, sputum, lymphadenopathy, and chest infiltrations. More than half of the patients (85.9%) were diagnosed with localized tuberculosis (pulmonary) and the others (14.1%) had extra-pulmonary or disseminated tuberculosis. At the time of this study, the majority of the patients (16.9%) had CD4 cell counts of less than 200 cell/mm3, with a median of 221 cell/mm3. Clinical outcomes demonstrated that among those who survived, 11.0% and 20.7% of the patients had completed treatment either > or = 6 or > or = 9 months, respectively, whereas 54.8% of patients were lost to follow-up, including 0.7% for MDR-TB. Diagnostic criteria for tuberculosis in this study were mainly clinical symptoms/signs and chest x-ray findings (31.0%).

    In the year 2001, 1459 Tuberculosis (TB) cases (43.1/100,000 population) were notified in Selangor. The highest age specific incidence rate was among those aged above 60 years and foreigners accounted for 15% of the cases notified. Fifteen percent of the TB cases were treated in the private sector where treatment efficacy and compliance could not be evaluated. Co- infection of Human Immunodeficiency Virus (HIV) infection with TB accounted for 51% of the TB deaths notified. Screening programmes in prisons and drug rehabilitation centres had detected 11.7% of HIV/TB coinfection among HIV positive inmates screened in these institutions.

    This retrospective study documents a strong correlation between tuberculin reactivity and the subsequent development of active tuberculosis in student nurses. 12% of the 25 student nurses with tuberculin reactions above 20 mm developed tuberculosis over a period of 2 years, compared to only 0.3% of the 341 student nurses with reactions of 20 mm or less. The implications of these findings for preventive therapy are discussed.

    Between January 1990 and December 1991, 100 cases of extrapulmonary tuberculosis were identified at the General Hospital Kota Bharu representing 11% of all the newly diagnosed tuberculosis. It was commonest in the third decade of life and the sites involved were the lymph nodes (34%), osteoarticular (14%), miliary (12%) and pleura (10%). Tuberculous lymphadenitis appears to be more common in females and younger patients. Fourteen patients had concurrent active pulmonary tuberculosis and in 36 others the chest X-rays showed satisfactory response to standard chemotherapy. Six patients died and six were lost to follow-up.
