Partnership in tuberculosis control through involvement of pharmacists in Delhi: An exploratory operational research study

Community pharmacists-led interventions in tuberculosis care: A systematic review

BACKGROUND

A multidisciplinary approach is required to tackle the tuberculosis (TB) epidemic, which is one of the most pressing public health concerns worldwide. However, community pharmacists are underutilized in TB programs.

OBJECTIVE

To identify community pharmacists-led interventions in TB management with their corresponding impacts in TB case detection and treatment outcomes.

METHODS

A systematic search was performed in six electronic databases and health organization websites, from database inception to August 2, 2022. Studies which described TB screening, referral and/or treatment monitoring by community pharmacists with their corresponding outcomes were screened and reviewed independently by two reviewers. The studies were checked for the risk of bias using Cochrane risk of bias tools. All data of included studies were analysed qualitatively and presented narratively.

RESULTS

The search yielded 8,121 studies and five reports for initial screening. Sixteen studies and two case study reports were included in this review. Community pharmacists were involved throughout the TB care cascade, contributing their services in TB screening, referrals and in directly observed treatment-short course (DOTS) program. These interventions showed improvements in the effective control and prevention of further spread of TB, which improves individual, community and population level outcomes.

CONCLUSIONS

The inclusion of community pharmacists into TB program can improve the continuity of care, bridging the gaps in TB case detection and treatment monitoring. Adequate training and support are essential, to further empower the role of community pharmacists in TB control and prevention, in building a TB-free world.

Epidemiology of molecular probes in Xpert MTB/RIF assay in Khyber Pakhtunkhwa, Pakistan

Regardless of a plethora of advanced diagnostics, TB and drug resistance remains a principal killer. We proposed gold nanoparticles (AuNPs) attached with probes to enhance the efficiency of GeneXpert MTB/RIF assay instead of conventional dye probes for molecular detection. A total of 15,000 samples were collected from TB suspects and subjected to Xpert MTB/RIF assay, where 6800 (45.3%) were detected as MTB positive, 280 (4.3%) were detected to harbor mutations in the RRDR, while invalid /errors were found in 690 (4.6%) cases. The mutations were detected by probe E, 199 (71.1%), while probes B and D, 30 and 26 (10% and 9%), respectively. In the Xpert MTB/RIF Assay were found mutations picked by probes E and B codons 529-533 (71%) and 512-518 (10%), respectively. The fast-rising works of TB nano-diagnostics, of Xpert probes, may improve by the applications of gold nanoparticle probes.
