    Asia has the highest burden of tuberculosis (TB) and latent TB infection (LTBI) in the world. Optimizing the diagnosis and treatment of LTBI is one of the key strategies for achieving the WHO 'End TB' targets. We report the discussions from the Asia Latent TubERculosis (ALTER) expert panel meeting held in 2018 in Singapore. In this meeting, a group of 13 TB experts from Bangladesh, Cambodia, Hong Kong, India, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Taiwan, Thailand and Vietnam convened to review the literature, discuss the barriers and propose strategies to improve the management of LTBI in Asia. Strategies for the optimization of risk group prioritization, diagnosis, treatment, and research of LTBI are reported. The perspectives presented herein, may help national programs and professional societies of the respective countries enhance the adoption of the WHO guidelines, scale-up the implementation of national guidelines based on the regional needs, and provide optimal guidance to clinicians for the programmatic management of LTBI.

    PMID: 23770860 MyJurnal
    A review of the epidemiology of tuberculosis, its contributing risk factors (excluding HIV) and the role of screening latent tuberculosis infection in Malaysia was done. Despite the global and domestic decrease in prevalence rates of tuberculosis in the past decade, there is an alarming increase in the trend of non communicable diseases in the country. High prevalence rates of major risk factors leading to reactivation of tuberculosis were seen within the population, with diabetes mellitus being in the forefront. The rising numbers in the ageing population of Malaysia poses a further threat of re-emergence of tuberculosis in the years to come. Economically, screening of diabetic patients with comorbidities for latent tuberculosis infection (LTBI) using two major techniques, namely tuberculin sensitivity (TST) and Interferon gamma release assay tests (IGRA) could be a viable option. The role of future research in the detection of LTBI in the Malaysian setting might be necessary to gauge the disease reservoir before implementing prophylactic measures for high risk groups involved.

  3. Fulltext A rare case of Tuberculous Prostatitis
    Nurul Yaqeen Esa, Mohammad Hanafiah, Marymol Koshy, Hilmi Abdullah, Ahmad Izuanuddin Ismail, Mohamed Fauzi Abdul Rani
    Journal of Clinical and Health Sciences, 2016;1:33-36.
    Tuberculous prostatitis is an uncommon form of tuberculosis infection. It is commonly seen in immunocompromised patients and in those of middle or advanced age. The diagnosis is often not straight forward due to the nature of its presentation. We report a case of tuberculous prostatitis in a young, healthy and immunocompetent patient, who initially presented with respiratory features, followed by episodes of seizures and testicular swelling. He was finally diagnosed with tuberculous prostatitis after prostatic biopsy. This case illustrates that in a high TB prevalence environment, when symptoms warrant, there should be a high clinical suspicion coupled with a thorough approach in order to arrive at a correct diagnosis of TB prostatitis.

    The discovery of heat shock protein 16 kDa antigen protein has deepen the understanding of latent tuberculosis since it was found to be primarily expressed by Mycobacterium tuberculosis during latent phase leading to the rapid optimization and development in terms of diagnosis and therapeutics. Recently, T cell receptor-like antibody has been explored extensively targeting various diseases due to its dual functionality (T cell receptor and antibody). In this study, a TCR-like domain antibody (A2/Ab) with the binding capacity to Mtb heat shock protein (HSP) 16 kDa antigen presented by major histocompatible complex (MHC) HLA-A*02 was successfully generated via biopanning against human domain antibody library. The generated antibody (A2/Ab) exhibited strong functionality and binding capacity against the target assuring the findings of this study to be beneficial for the development of latent tuberculosis diagnosis and immunotherapeutics in future.

  5. Fulltext Role of Mantoux test in the diagnosis of tuberculosis
    Loh KY
    Malays Fam Physician, 2011;6(2):85-86.
    PMID: 25606232 MyJurnal
    Mantoux test is a sensitive but non-specific in the diagnosis of active tuberculosis. The positive cut-off of 10 mm in a person without BCG and 15 mm with previous BCG is appropriate. The interpretation of Mantoux needs to be correlated to the patient’s clinical context. Mantoux test may have a role in assisting extrapulmonary tuberculosis and latent tuberculosis in children.

  7. Fulltext Prevalence and correlates of latent tuberculosis infection among employees of a high security prison in Malaysia
    Al-Darraji HA, Tan C, Kamarulzaman A, Altice FL
    Occup Environ Med, 2015 Jun;72(6):442-7.
    PMID: 25794506 DOI: 10.1136/oemed-2014-102695
    OBJECTIVES: Although prison employees share the same tuberculosis (TB) risk environment with prisoners, the magnitude of TB problems among prison employees is unknown in most resource-limited prisons. This survey was conducted to investigate the prevalence and correlates of tuberculin skin test (TST) positivity among employees in Malaysia's largest prison.

    METHODS: Consented, full-time prison employees were interviewed using a structured questionnaire that included sociodemographic data, history of working in the correctional system and TB-related risk. TST was placed intradermally and read after 48-72 h. Induration size of ≥10 mm was considered positive. Logistic regression analyses were conducted to explore associations with TST positivity.

    RESULTS: Of the 445 recruited prison employees, 420 (94.4%) had complete data. Most were young (median=30.0 years) men (88.8%) who had only worked at this prison (76.4%) for a median total employment period of 60 months (IQR 34.5-132.0). The majority were correctional officers, while civilian employees represented only 7.6% of the sample. Only 26 (6.2%) reported having ever been screened for TB since employment. Prevalence of TST positivity was 81% and was independently associated with longer (≥12 months) prison employment (AOR 4.9; 95% CI 1.5 to 15.9) and current tobacco smoking (AOR=1.9, 95% CI 1.2 to 3.2).

    CONCLUSIONS: Latent TB prevalence was high in this sample, approximating that of prisoners in this setting, perhaps suggesting within prison TB transmission in this facility. Formal TB control programmes for personnel and prisoners alike are urgently needed within the Malaysian correctional system.

    Prisons continue to fuel tuberculosis (TB) epidemics particularly in settings where access to TB screening and prevention services is limited. Malaysia is a middle-income country with a relatively high incarceration rate of 138 per 100,000 population. Despite national TB incidence rate remaining unchanged over the past ten years, data about TB in prisons and its contribution to the overall national rates does not exist. This survey was conducted to address the prevalence of latent TB infection (LTBI) in Malaysia's largest prison.

  10. Fulltext Latent tuberculosis infection screening in foreign-born populations: a successful mobile clinic outreach model
    Morano JP, Zelenev A, Walton MR, Bruce RD, Altice FL
    Am J Public Health, 2014 Aug;104(8):1508-15.
    PMID: 24922157 DOI: 10.2105/AJPH.2014.301897
    OBJECTIVES: We evaluated the efficacy of a mobile medical clinic (MMC) screening program for detecting latent tuberculosis infection (LTBI) and active tuberculosis.
    METHODS: A LTBI screening program in a MMC in New Haven, Connecticut, used medical surveys to examine risk factors and tuberculin skin test (TST) screening eligibility. We assessed clinically relevant correlates of total (prevalent; n = 4650) and newly diagnosed (incident; n = 4159) LTBI from 2003 to 2011.
    RESULTS: Among 8322 individuals, 4159 (55.6%) met TST screening eligibility criteria, of which 1325 (31.9%) had TST assessed. Similar to LTBI prevalence (16.8%; 779 of 4650), newly diagnosed LTBI (25.6%; 339 of 1325) was independently correlated with being foreign-born (adjusted odds ratio [AOR] = 8.49; 95% confidence interval [CI] = 5.54, 13.02), Hispanic (AOR = 3.12; 95% CI = 1.88, 5.20), Black (AOR = 2.16; 95% CI = 1.31, 3.55), employed (AOR = 1.61; 95% CI = 1.14, 2.28), and of increased age (AOR = 1.04; 95% CI = 1.02, 1.05). Unstable housing (AOR = 4.95; 95% CI = 3.43, 7.14) and marijuana use (AOR = 1.57; 95% CI = 1.05, 2.37) were significantly correlated with incident LTBI, and being male, heroin use, interpersonal violence, employment, not having health insurance, and not completing high school were significantly correlated with prevalent LTBI.
    CONCLUSIONS: Screening for TST in MMCs successfully identifies high-risk foreign-born, Hispanic, working, and uninsured populations and innovatively identifies LTBI in urban settings.

  11. Fulltext Prevalence and risk factors of latent tuberculosis infection among health care workers in Malaysia
    Rafiza S, Rampal KG, Tahir A
    BMC Infect Dis, 2011;11:19.
    PMID: 21244645 DOI: 10.1186/1471-2334-11-19
    BACKGROUND: Health care workers are exposed to patients with tuberculosis and are at risk of nosocomial infection. The aim of this study was to determine the prevalence and factors associated with latent tuberculosis infection among health care workers in Malaysia and also to evaluate the agreement between Quantiferon TB Gold in tube test with Tuberculin Skin Test.
    METHODS: A cross sectional study was conducted at four randomly selected hospitals in the Klang Valley from December 2008 to May 2009. Self administered questionnaire was used to obtain information on health care workers and possible risk factors. The response rate for this study was 90.8% with 954 respondents completed the questionnaire and were tested with Quantiferon TB Gold in tube for latent tuberculosis infection. Agreement between Quantiferon TB Gold in tube and Tuberculin Skin Test was assessed among 95 health care workers who consented to undergo both tests.
    RESULTS: The overall prevalence of latent tuberculosis infection among health care workers was 10.6% (CI: 8.6%; 12.6%). Factors significantly associated with latent tuberculosis infection were aged 35 years and older [9.49 (CI: 2.22; 40.50)], history of living in the same house with close family members or friends who had active tuberculosis [8.69 (CI: 3.00; 25.18)], worked as a nurse [4.65 (CI: 1.10; 19.65)] and being male [3.70 (CI: 1.36; 10.02)]. Agreement between Quantiferon TB Gold in tube test and tuberculin skin test at cut-off points of 10 mm and 15 mm was 50.5% and 82.1% respectively. However, Kappa-agreement was poor for both cut-off points.
    CONCLUSION: The prevalence of latent tuberculosis infection in Malaysia was relatively low for an intermediate TB burden country. We could not comment on the occupational risk of latent tuberculosis infection among health care worker compared to the general population as there were no prevalence data available for latent tuberculosis infection in the general population. Kappa agreement between Quantiferon TB gold in-tube and tuberculin skin test was poor.

  12. Fulltext Preventing tuberculosis in healthcare workers of the radiology department: a Malaysian perspective
    Tan L, Kamarulzaman A
    Biomed Imaging Interv J, 2006 Jan;2(1):e3.
    PMID: 21614220 MyJurnal DOI: 10.2349/biij.2.1.e3
    Tuberculosis (TB) is a well recognised occupational hazard for healthcare workers (HCWs). Concerns on the safety of healthcare settings in Malaysia was raised following a report of 25 HCWs working in 11 general hospitals in Malaysia who were infected with TB in 2004 being publicised in the media recently. As the disease burden in general is high in Malaysia, due attention should be given to this disease in our healthcare facilities including the radiology department, an often neglected area in TB infection control programmes. This article focuses on the key control measures that can be implemented in radiology departments in a developing country with limited resources.

    Eradication of tuberculosis seems to be a long way off especially with the growing of drug resistance tuberculosis and HIV co-infection tuberculosis. The gaps in our knowledge and the limited sensitive and specific biomarkers especially for latent tuberculosis infection make it defensive. The fate of tuberculosis treatment ranged from cured to failure and there are many risk factors involved apart from the immune state and age. Therefore, this review focuses on the understanding of tuberculosis disease progression and the associated risk factors of the events in the disease progression. This article also highlights the diagnostic and predictive marker that may predict the disease progression. In addition, this review highlights the potential use of rifabutin in tuberculosis treatment regimen. It is hoped that this review could give an overview on future directions of research in tuberculosis.

  14. Fulltext Close contact investigation of TB in high-burden, low- and middle-income countries

    PMID: 25893066 MyJurnal
    Tuberculosis (TB) remains a very common disease in most of the low- and middle-income countries. As a result of high disease burden, TB control measures in these countries are usually concentrated on intensifying active disease case-finding and early treatment of infectious TB. On the contrary, in countries with low disease burden, the focus is on contact investigation to identify latently infected individuals and prophylactically treating them to prevent disease reactivation and transmission. These two strategies are deemed important for the effective TB control. Nonetheless, WHO cautions that targeted contact investigation and latent TB infection (LTBI) treatment should only be undertaken by countries that have the operational capacity/ resources and have achieved ≥ 85% treatment success rate of active TB. The screening of LTBI is further challenged by the lack of a “gold standard” test to identify and validate individuals with this condition. Tuberculin skin test (TST) is still the preferred investigation as it is cheap, widely available and validated in many trials. The sensitivity and specificity of the newer test—interferon gamma release assay (IGRA) for LTBI screening has been encouraging in low prevalence countries. However, the evidence supporting such usage remains uncertain in high burden settings. Diagnosis of LTBI should adhere to the strict criteria outlined in the guidelines to avoid misdiagnosing active TB as LTBI. The treatment of the latter involved only one or two anti-TB drugs. It has been demonstrated that in the properly conducted contact screening and LTBI treatment, chances of the emergence of multi-drug-resistant TB is very low.

  15. Fulltext Epidemiology of latent tuberculosis infection among patients with and without diabetes mellitus
    Swarna Nantha Y, Puri A, Mohamad Ali SZ, Suppiah P, Che Ali SA, Ramasamy B, et al.
    Fam Pract, 2017 09 01;34(5):532-538.
    PMID: 28369346 DOI: 10.1093/fampra/cmx017
    Background: Individuals with type 2 diabetes mellitus (DM) are at a greater risk of tuberculosis (TB) reactivation. There is a paucity of information about the risk factors associated with latent tuberculosis infection (LTBI) in patients with diabetes.

    Objective: We conducted an observational study to compare the prevalence and risk factors associated with LTBI factors in Malaysian adults with and without DM.

    Methods: Four hundred and four patients with DM and 359 patients with non-DM at a regional primary care clinic were recruited as participants in this case-control study. The tuberculin sensitivity test (TST) was performed. The presence of LTBI was defined by a TST value of 10 mm in DM patients and 10 mm in the non-DM group. A logistic regression model was used to identify variables associated with LTBI.

    Results: There was no statistical significant difference in the prevalence rates seen between the DM and non-DM group of the study. LTBI prevalence among patients with DM was 28.5%. The proportion of patients in the non-DM group with LTBI was 29.2%. When a critical cut-off of 8 mm was used, the adjusted odds ratio of LTBI in DM patients was 1.88 (95% confidence interval: 1.22-2.82). Smoking was an independent risk factor for LTBI regardless of DM status. HbA1c levels or anthropometric measurements were not associated with LTBI in diabetic patients.

    Conclusions: There is no significant risk of contracting LTBI in DM patients using the standard 10-mm TST cut-off. Nonetheless, using lower cut-offs in a DM population appear valid. Smoking is an important predictor of LTBI.

  16. Genomic plasticity between human and mycobacterial DNA: A review
    Danjuma L, Ling MP, Hamat RA, Higuchi A, Alarfaj AA, Marlina, et al.
    Tuberculosis (Edinb), 2017 12;107:38-47.

    Mycobacterium tuberculosis has a remarkable ability of long-term persistence despite vigorous host immunity and prolonged therapy. The bacteria persist in secure niches such as the mesenchymal stem cells in the bone marrow and reactivate the disease, leading to therapeutic failure. Many bacterial cells can remain latent within a diseased tissue so that their genetic material can be incorporated into the genetic material of the host tissue. This incorporated genetic material reproduces in a manner similar to that of cellular DNA. After the cell division, the incorporated gene is reproduced normally and distributed proportionately between the two progeny. This inherent adoption of long-term persistence and incorporating the bacterial genetic material into that of the host tissue remains and is considered imperative for microbial advancement and chemotherapeutic resistance; moreover, new evidence indicates that the bacteria might pass on genetic material to the host DNA sequence. Several studies focused on the survival mechanism of M. tuberculosis in the host immune system with the aim of helping the efforts to discover new drugs and vaccines against tuberculosis. This review explored the mechanisms through which this bacterium affects the expression of human genes. The first part of the review summarizes the current knowledge about the interactions between microbes and host microenvironment, with special reference to the M. tuberculosis neglected persistence in immune cells and stem cells. Then, we focused on how bacteria can affect human genes and their expression. Furthermore, we analyzed the literature base on the process of cell death during tuberculosis infection, giving particular emphasis to gene methylation as an inherited process in the neutralization of possibly injurious gene components in the genome. The final section discusses recent advances related to the M. tuberculosis interaction with host epigenetic circuitry.

  17. Tuberculosis screening in a novel substance abuse treatment center in Malaysia: implications for a comprehensive approach for integrated care
    Al-Darraji HA, Wong KC, Yeow DG, Fu JJ, Loeliger K, Paiji C, et al.
    J Subst Abuse Treat, 2014 Feb;46(2):144-9.
    PMID: 24074846 DOI: 10.1016/j.jsat.2013.08.023
    People who use drugs (PWUD) represent a key high risk group for tuberculosis (TB). The prevalence of both latent TB infection (LTBI) and active disease in drug treatment centers in Malaysia is unknown. A cross-sectional convenience survey was conducted to assess the prevalence and correlates of LTBI among attendees at a recently created voluntary drug treatment center using a standardized questionnaire and tuberculin skin testing (TST). Participants (N=196) were mostly men (95%), under 40 (median age=36 years) and reported heroin use immediately before treatment entry (75%). Positive TST prevalence was 86.7%. Nine (4.6%) participants were HIV-infected. Previous arrest/incarcerations (AOR=1.1 for every entry, p<0.05) and not being HIV-infected (AOR=6.04, p=0.03) were significantly associated with TST positivity. There is an urgent need to establish TB screening and treatment programs in substance abuse treatment centers and to tailor service delivery to the complex treatment needs of patients with multiple medical and psychiatric co-morbidities.

  18. Fulltext A review of tuberculosis research in Malaysia
    Swarna Nantha Y
    Med J Malaysia, 2014 Aug;69 Suppl A:88-102.
    PMID: 25417956 MyJurnal
    One hundred seventy four articles related to tuberculosis were found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. One hundred fifty three articles were selected and reviewed on the basis of clinical relevance and future research implications. Topics related to epidemiology, clinical presentation, detection methods and treatment were well researched. However, limited information was available on screening and behavioural interventions. The younger population were more vulnerable to tuberculosis infection and had higher prevalence of risk factors that reactivate tuberculosis infection. Screening of tuberculosis was conducted primarily on healthcare workers, tuberculosis contacts, prisoners and foreign workers. Data on the clinical presentation of pulmonary and extrapulmonary tuberculosis was comprehensive. There was a general focus on related risk factors such as HIV and diabetes mellitus. A great degree of information was available on the treatment and various detection methods to identify tuberculosis. The efficacy and the practicality of investigative methods was analysed in this review. In conclusion, the direction of research should be aimed at novel preventive and control measures of tuberculosis. There should be emphasis on the screening of high risk groups (other than HIV) within the population namely diabetic patients, smokers and immunosuppressed individuals. The design of health policies should be guided by information gathered from research evaluation of communitybased behavioural interventions.

    The Asia-Pacific Working Group on inflammatory bowel disease (IBD) was established in Cebu, Philippines, under the auspices of the Asian Pacific Association of Gastroenterology with the goal of improving IBD care in Asia. This consensus is carried out in collaboration with Asian Organization for Crohn's and Colitis. With biologic agents and biosimilars becoming more established, it is necessary to conduct a review on existing literature and establish a consensus on when and how to introduce biologic agents and biosimilars in the conjunction with conventional treatments for ulcerative colitis (UC) and Crohn's disease (CD) in Asia. These statements also address how pharmacogenetics influence the treatments of UC and CD and provide guidance on response monitoring and strategies to restore loss of response. Finally, the review includes statements on how to manage treatment alongside possible hepatitis B and tuberculosis infections, both common in Asia. These statements have been prepared and voted upon by members of IBD workgroup employing the modified Delphi process. These statements do not intend to be all-encompassing and future revisions are likely as new data continue to emerge.

    MyJurnal
    Tuberculosis (TB) has become a worldwide public concern with 10.4 million new cases reported in 2015 and 1.4 million deaths. More importantly, an increase in trend in TB incidence among healthcare workers has become a major concern. Therefore, the present study was conducted to explore the knowledge and practice towards TB and the factors associated with it among nurses in a teaching hospital. The present study used cross-sectional design and stratified sampling method. A total of 275 nurses in a teaching hospital participated in this study. The knowledge and practice on management of TB was measured using a structured questionnaire. Majority of the respondents had good knowledge and practice on management of TB represented by 70.2% and 63.3%, respectively. However, knowledge gap (1.8%) and practice gap (0.4%) were identified in method of sputum collection. Work place setting was the only demographic factor found significantly associated with level of knowledge and practice (p=0.028). Level of knowledge and practice on management of TB identified among nurses was not associated with many socio-demographic factors. Nurses as frontline healthcare workers are at high risk of being exposed due to frequent contact with various patients especially those who are undiagnosed and TB suspect patients. Hence, implementation of TB Infection Control (TBIC) measures is important to minimize the risk of infection and cross-infection within hospital.
