METHODS: A retrospective study was conducted to recognize the epidemiology facts of EPTB. Individual data for EPTB patients were collected from TB registers, laboratory TB registers, treatment cards and TB medical personal files into a standardized study questionnaire. Crude (COR) and adjusted odds ratios (AOR) and 95% confidence intervals (CI) were determined to assess the risk factors for EPTB and unsuccessful treatment outcomes.
RESULTS: There were 1222 EPTB patients presenting 13.1% of all TB cases during 2006-2008. Pleural effusion and lymph node TB were the most frequent types and accounted for 45.1% of all EPTB cases among study participants. Treatment success rate was 67.6%. The best treatment completion rates were found in children ≤15 years (0.478 [0.231-1.028]; p = 0.05). On multivariate analysis, age group 56-65 years (1.658 [1.157-2.376]; p = 0.006), relapse cases (7.078 [1.585-31.613]; p = 0.010), EPTB-DM (1.773 [1.165-2.698]; p = 0.008), patients with no formal (2.266 [1.254-4.095]; p = 0.001) and secondary level of education (1.889 [1.085-3.288]; p = 0.025) were recorded as statistically positive significant risk factors for unsuccessful treatment outcomes. Patients at the risk of EPTB were more likely to be females (1.524 [1.311-1.746]; p
OBJECTIVE: The aim of this paper is to introduce readers to the platforms on which Tuberculosis participants interact, to discuss reasons for and risks associated with TB-related activity, and to review research related to the potential impact of individual participation on TB outcomes.
METHODS: Research and online content related to Tuberculosis online activity is reviewed, however, the difficulty in accurate prescribing and adhering to these protocols and the emergence of M. tuberculosis strains resistant to multiple drugs and drug-drug interactions that interfere with optimal treatment of Tuberculosis and co-infected patients with the different disease has generated a pressing need for improved Tuberculosis therapies.
RESULTS: Together with the ominous global burden of Tuberculosis, those shortcomings of current medication have contributed to a renewed interest in the development of improved drugs and protocols for the medication of Tuberculosis. This article features obstacles related with the enhanced utilization of existing drugs and difficulties related with the advancement of enhanced products, concentrating on perspectives characteristic in Tuberculosis drug clinical improvement. The participation includes peer support, advocacy, self-expression, seeking and sharing TB information, improving approaches to Tuberculosis data management, and humour.
CONCLUSION: This article highlights hurdles related to the optimised use of existing drugs and challenges related to the development of improved products, focusing on aspects inherent in Tuberculosis drug clinical development. Concluding comments offer processes for more efficient development of Tuberculosis therapies and increase the quality of life.
METHODS: We conducted a retrospective review of TB cases notified in Sabah, Malaysia, between 2012 and 2018. Using data from the state's 'myTB' notification database, we calculated the case notification rate and described trends in the epidemiology, diagnostic practices and treatment outcomes of TB in Sabah within this period. The Chi-squared test was used for determining the difference between two proportions.
RESULTS: Between 2012 and 2018 there were 33 193 cases of TB reported in Sabah (128 cases per 100 000 population). We identified several geographic hotspots, including districts with > 200 cases per 100 000 population per year. TB rates increased with age and were highest in older males. Children drug resistant (MDR) TB prevalence was low (0.3% of TB cases), however, rapid diagnostic test coverage was low (1.2%) and only 18% of all cases had a positive culture result. Treatment success was 83% (range: 81-85%) in those with drug-sensitive TB and 36% (range: 25-45%) in cases of MDR-TB.
CONCLUSION: Between 2012 and 2018, TB notifications in Sabah State equated to 20% of Malaysia's total TB notifications, despite Sabah representing only 10% of Malaysia's population. We found hotspots of TB in urbanised population hubs and points of migration, as well as evidence of late presentation and diagnosis. Ensuring universal health coverage and expansion of GeneXpert® coverage is recommended to reduce barriers to care and early diagnosis and treatment for TB.
SETTING: The study was conducted at a tertiary hospital in the northern region of Peninsular Malaysia. Methods Action research methodology was used.
MAIN OUTCOME MEASURE: Pharmaceutical care issues.
RESULTS: The prevalence of diabetes mellitus among newly diagnosed tuberculosis patients was 15% (53/352). Out of 53 patients identified, 35 participated in the study. Patients' ages ranged between 29 and 73 years (mean of 52 ± 10 years). The male: female ratio was 1.7:1. Pharmaceutical care issues identified by pharmacists were nonadherence, uncontrolled diabetes mellitus, adverse drug reactions and individual patient's medication related problems. Pharmacists were able to intervene and resolve some of the pharmaceutical care issues.
CONCLUSION: Pharmacists played an important role in integrating the provision of care for tuberculosis and diabetes mellitus by providing individualised pharmaceutical care management. There still remains a need to address logistic barriers that impinged on the ability to conduct the pharmaceutical care service to its full potential.
Methods: A prospective longitudinal study was conducted in the Sindh province, Pakistan. A total of 508 TB children in multicenter hospitals under ATT were assessed for ADRs. Naranjo Causality Assessment and Hartwig's Severity Assessment Scale were used.
Results: A total of 105 ADRs were reported in 67 (13.2%) of 508 patients. Gastrointestinal disorders were the most frequently observed ADRs (65.7%), followed by arthralgia (24.8%). Around 65 (61.9%) of ADRs were identified as probable and 78 (74.3%) as mild severe ADRs during the study. A total of four cases of mild hepatotoxicity were observed among children. On multivariate analysis, the independent variables which had statistically significant positive association with ADRs were female (OR; 2.66, P = 0.004), retreatment (OR; 22.32, P = ≤ 0.001), and absence of BCG scar (OR; 17.84, P = 0.001).
Conclusions: The finding of the current study suggests that close monitoring of females, patients with previous TB treatment, and those without BCG is warranted at the study site.
MATERIALS AND METHODS: In this study, we focus on two important drugs used for TB treatment - rifampicin (RIF) and isoniazid (INH) - and report a detailed study of RIF-loaded poly lactic-co-glycolic acid (PLGA) NPs and INH modified as INH benz-hydrazone (IH2) which gives the same therapeutic effect as INH but is more stable and enhances the drug loading in PLGA NPs by 15-fold compared to INH. The optimized formulation was characterized using particle size analyzer, scanning electron microscopy and transmission electron microscopy. The drug release from NPs and stability of drug were tested in different pH conditions.
RESULTS: It was found that RIF and IH2 loaded in NPs release in a slow and sustained manner over a period of 1 month and they are more stable in NPs formulation compared to the free form. RIF- and IH2-loaded NPs were tested for antimicrobial susceptibility against Mycobacterium tuberculosis H37Rv strain. RIF loaded in PLGA NPs consistently inhibited the growth at 70% of the minimum inhibitory concentration (MIC) of pure RIF (MIC level 1 µg/mL), and pure IH2 and IH2-loaded NPs showed inhibition at MIC equivalent to the MIC of INH (0.1 µg/mL).
CONCLUSION: These results show that NP formulations will improve the efficacy of drug delivery for TB treatment.
DISCUSSION: We present a summary of the current and novel TPT regimens, including current evidence of use with antiretroviral regimens (ART). We review challenges and opportunities to scale-up TB prevention within HIV programmes, including the use of differentiated care approaches and demand creation for effective TB/HIV services delivery. TB preventive vaccines and diagnostics, including optimal algorithms, while important topics, are outside of the focus of this commentary.
CONCLUSIONS: A number of new tools and strategies to make TPT a standard of care in HIV programmes have become available. The new TPT regimens are safe and effective and can be used with current ART, with attention being paid to potential drug-drug interactions between rifamycins and some classes of antiretrovirals. More research and development is needed to optimize TPT for small children, pregnant women and drug-resistant TB (DR-TB). Effective programmatic scale-up can be supported through context-adapted demand creation strategies and the inclusion of TPT in client-centred services, such as differentiated service delivery (DSD) models. Robust collaboration between the HIV and TB programmes represents a unique opportunity to ensure that TB, a preventable and curable condition, is no longer the number one cause of death in PLHIV.
