This included systematic engagement of hospital administration and all specialist doctors, staff training and regular facility-based review meetings. HDL was associated with 35% increase in childhood TB notifications in 2015 (versus 2014) in HDL sites as compared to 16% increase in non-HDL sites. The increase was seen across provinces, age-groups and sexes, but did not correlate with presence of Xpert MTB/RIF®?or “screeners” (health workers deployed to screen children for TB).展开更多

Pakistan ranks 5th high burden countries for drug-susceptible and 6th among drug-resistant TB patients [1]. Objectives of the study were to assess the prevalence of TB-HIV Co-infection at the designated Sentinel Sites across Pakistan. A cross-sectional study is based on retrospective record review of routinely maintained TB program data at all 17 designated sentinel sites of TB Control Program from 2013-15. Among the screened TB patients 145 (0.66%) were found HIV reactive. The prevalence of HIV was higher (1.02%) in extra-pulmonary and male TB patients (1.23 %) as compared to pulmonary (0.55%) and female patients (0.09%). Scale up TB surveillance activities, integrating TB-HIV care services, active case finding among key affected populations will have a positive impact on TB-HIV co-infection and disease control.展开更多

Objective: To assess the change in case notification by private healthcare providers as well as effect on sputum smear positivity rate at private laboratories after introduction of incentives. Design: A comparative cross-sectional study based on routinely maintained National TB Control Program data collected before and after the introduction of incentives (2014 and 2016). Results: In 2016, TB case notification increased by 71% after cash incentives was introduced. Among the 618 private healthcare providers who enrolled and maintained participation in the Public Private Mix program, only 1% of the GPs contributed to 19% increase in case notification, whereas 27% GPs had reported a reduced number of cases compared to the pre-intervention period. After incentives, slide positivity rate for diagnostic declined by 1.9% and follow-up increased by 0.6%. Number of slides for diagnostic and follow-up testing increased by 82% and 72% respectively. Conclusion: Engaging the private healthcare sector, by providing cash incentives to private health care Provider’s is an effective strategy for providing a substantial increase in National TB case notification.展开更多

There was a 55% increase in childhood TB notifications in 2014 compared to 2012 in facilities with screeners (n = 8) compared to 40% increase in facilities without screeners (n = 22). This apparent association disappeared when stratified by presence of “trained pediatrician” whose introduction was associated with a massive increase in notifications while transfer was associated with a marked decrease. In conclusion, screeners were not associated with increase in pediatric TB case notifications.展开更多

The biology of the mycobacterium tuberculosis is complicated and has affected the control as well as elimination of the disease. Nigeria is one of the countries with high incidence and prevalence of TB. The late and low case detection has been a major problem with National TB control program, caused by passive case finding strategy practiced by the country. A shift from the passive and active case search has been recommended for detection of missing cases of TB and improved program performance. The proximity of TB contact is a major determinant of disease transmission. However, maximizing early case detection and prompt treatment of notified cases is very useful in (TB) control especially in high burden countries. The tracking of TB contacts provides a good platform for early diagnosis, educating the household on TB disease and infection control as well as breaking the chain of transmission. The objective of the study is to ascertain effectiveness of contact tracing on Tuberculosis case detection. The study is a retrospective quasi experimental with quantitative arm. The study was conducted in Abia State, one of the South Eastern States of Nigeria. A pre-tested questionnaire was used for data collection and analyzed with SPSS. A total of 168 and 162 index cases of TB were recruited for both intervention and control facilities. The 168 index TB cases yielded 301 TB contacts. The result revealed 55% contact/index ratio, presumptive TB yield of 130 (43.2%) and TB yield of 68 (22.6%). The cases registered in the State increased from 336 to 417 and p value = 0.001, while presumptive TB and BCG vaccination were major predictors. The study shows that tracing contact of index TB cases is an effective and complementary method of finding undetected cases of TB.展开更多

It reached epidemic proportions in Europe and North America during the 18th and 19th centuries. The incubation period is 2 - 6 weeks and the control has been complicated with emergence of HIV and drug-resistant TB. In 1993, World Health Organization (WHO) declared TB a global emergency. However, despite the concerted effort of National TB control programs, adoption and implementation of Stop TB strategy, TB has remained a major public health challenge with high mortality rate, especially in developing countries. Methodology: This is a descriptive study, evaluated using the positivist/quantitative approach. The study was conducted at FederalMedical Centre Umuahia, a tertiary specialist hospital with comprehensive TB/HIV treatment services. All the presumptive drug-resistant TB cases and symptomatic PLHIV were screened for HIV and their sputum specimens were tested for tuberculosis using the Gene xpert and the Ziehl- Neelsen technique for detecting Acid Fast bacilli. A pretested structured questionnaire was used tocollect the demographic data and other essential data from the presumptive TB and laboratory registers such as total number of TB presumptive cases registered HIV status, AFB status and rifampicin status within the study period. Result: A total of 493 presumptive TB cases were screened in the study, 49.9% were HIV positive while 50.05% were HIV negative. More so, 77.85% of thescreened cases were AFB negative and 22.15% were AFB positive. Moreover, 11% of the TB/HIV co-infected patients were rifampicin positive. Interestingly among the 493 cases screened with gene xpert machine, 3.6% were rifampicin positive. Furthermore, 3.6% of the HIV negative cases were rifampicin positive while 1.6% of the HIV positive cases were rifampicin positive. Discussion: The data depict lower rifampicin resistance among HIV positive cases than HIV negative cases. The implication for public health professionals is to intensify equitable and unbiased search for resistant TB cases among smear negative and positive cases.展开更多
