The effect of the Covid-19 pandemic on Tuberculosis (TB) case notification in Ogun State, Nigeria.

Introduction: COVID-19 pandemic has resulted in disruptions in delivery of Tuberculosis services especially, in resource-limited settings. Provisional data by the WHO from 84 countries indicates that about 1.4 million fewer people received care for tuberculosis in 2020 than in 2019. This study assessed the effect of COVID-19 pandemic on tuberculosis case notification rates in Ogun state, Nigeria. Methods: A retrospective review of presumptive TB and diagnosed TB cases that were notified in 2019 and 2020. Analysis was done using Epi-info version 7.2.3.1. Level of statistical significance was p < 0.05. Results: A total of 3102 and 3326 confirmed cases were reported in 2019 and 2020 respectively with an increase of 7.2%. There was significant decline in total number of cases notified in Q2, 2020 compared to 2019 (p=0.001) with a significant increase in proportion of TB cases notified by private facilities from 11.65% in 2019 to 20.27% in 2020. Conclusion: Total TB cases notified in Ogun state increased during the covid-19 pandemic. There was significant decline in TB cases during the lockdown but an increase in proportion of TB cases notified by private facilities demonstrating that private facilities can withstand disruptions to TB case notifications due to the Covid-19 pandemic.

Outcome of community-initiated treatment of drug-resistant tuberculosis patients in Lagos, Nigeria.

BACKGROUND: With the improvement in the capacity to diagnose multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) patients due to the increased number of GeneXpert machines in Nigeria, the number of patients diagnosed surpassed the bed capacity at MDR-TB treatment centres. Community DR-TB treatment is an important option to improve access to care for MDR/RR-TB patients. However, few studies have determined the outcome of community management of MDR-TB patients, which this study aims to address. METHODS: We conducted a retrospective study of MDR/RR-TB patients initiated on treatment in the community in Lagos, Nigeria, between 1 January 2015 and 31 December 2016. Data were retrieved from DR-TB treatment cards/registers. The treatment outcomes of these patients were assessed at the end of treatment and categorized according to national TB guidelines. RESULTS: A total of 150 DR-TB patients commenced treatment during the study period. Adherence was 64.7%, with the majority of patients experiencing mild (56.5%) adverse drug events. Treatment was successful in 70% of patients. The only predictor of successful treatment was treatment adherence. CONCLUSIONS: The study shows that community initiation of MDR-TB treatment is feasible and results in a high treatment success rate. Adherence counselling before and during treatment is essential for a favourable treatment outcome.

Trend of tuberculosis case notification and treatment outcome in Lagos State, Nigeria: a 5-year retrospective study.

Background: This study assessed trends of tuberculosis (TB) case notification rate (CNR) and treatment outcomes between 2011 and 2015 in Lagos State, Nigeria. Methods: A retrospective review of TB notification data to the Lagos State Tuberculosis and Leprosy Control Programme (LSTBLCP) between 1 January 2011 and 31 December 2015 was conducted. Results: A total of 44 516 TB cases were notified during the study period, representing 9.4% of the national figure. The male:female ratio was 1.3:1. About 53%, 44.1% and 2.7% of patients were smear positive, smear negative and extrapulmonary TB cases, respectively. TB notification increased by 12.2% between 2011 and 2013 and subsequently declined by 7.2% in 2015 relative to 2013. The TB CNR declined from 82.9 per 100 000 in 2013 to 72.1 per 100 000 in 2015. However, directly observed treatment short course (DOTS) and microscopy site expansion increased from 0.3 to 0.64 per 25 000 population and from 0.16 to 0.4 per 50 000 population, respectively, from 2011 to 2015. Similarly, there was a slight increase in treatment success rate, from 80.1% in 2011 to 82% in 2015. Conclusion: The CNR declined in Lagos State despite an increasing trend in DOTS and microscopy site expansions between 2013 and 2015. The LSTBLCPs need to re-engineer current strategies of active TB case findings in order to improve case notification in the state.

FACTORS ASSOCIATED WITH TB/HIV CO-INFECTION AMONG DRUG SENSITIVE TUBERCULOSIS PATIENTS MANAGED IN A SECONDARY HEALTH FACILITY IN LAGOS, NIGERIA.

BACKGROUND: This study assessed factors associated with TB/HIV co-infection among TB patients managed in a secondary health facility in Lagos Nigeria. MATERIALS AND METHODS: A retrospective review of treatment cards of patients seen at a secondary referral hospital between January 1 2014 and December 31 2014 was conducted. Treatment outcomes and factors associated with TB/HIV co-infection were assessed. RESULTS: Of the 334 records of patients reviewed, the proportion of patients with TB/HIV co-infection was 21.6%. The odds of having TB/HIV co-infection was 2.7 times higher among patients above 40 years than patients less than 25 years (AOR 2.7 95% CI 1.1 - 6.5, p =0.030). In addition, the odds of having TB/HIV co-infection was 3.3 higher among extra-pulmonary TB cases (AOR 3.3; 95% CI 1.2 - 9.5; p = 0.026) and 2.1 times higher among retreated patients (AOR 2.1; 95% CI 1.1 - 3.9; p = 0.017) than pulmonary TB and new patients respectively. The chance of having TB/HIV co-infection was 2.7-fold more in patients with poor treatment outcomes than patients with treatment success (AOR 2.7; 95%CI 1.3 - 5.4; p =0.006). CONCLUSION: TB/HIV co-infection rate was high in the study area. There is need to put measures in place to improve treatment outcomes of TB/HIV co-infected patients.

Spatial distribution of leprosy in Nigeria.

Background: Despite achieving the WHO elimination target of less than 1/10,000 population in 1998 at the national level, there are still pockets of relative high endemicity of leprosy in Nigeria. This study used spatial analytic techniques to determine the spatial distribution of leprosy in Nigeria. Methods: The study is an ecological study of secondary data of new leprosy cases reported to the National TB and Leprosy Control Programme (NTBLCP) in Nigeria, 2010­2014. The 36 states and Federal Capital Territory were used as the unit of geographical analysis. The global Moran's I and Local Moran's I (LISA) test were used to measure spatial autocorrelation and significant levels were taken at P < , 0·05. Results: A total of 17,356 new leprosy cases were notified over 5 years (2010­2014) in Nigeria. A majority of the cases were multi-bacillary 16,037 (92·4%) while 1319 (7·6%) were pauci-bacillary. A total of 1569 (9%) children were reported with leprosy. The leprosy case detection rate increased slightly from 2·21/100,000 in 2010 to 2·24/100,000 in 2012 and declined to 1·66/100,000 population in 2014. Significant clustering of average annual leprosy case detection rate was observed in Kebbi state only, while childhood leprosy was significantly clustered in four states namely Sokoto, Kebbi, Rivers and Zamfara states. Conclusion: The study observed a significant clustering of leprosy case detection rate in Nigeria. The findings can serve as a useful guide to the national leprosy control programme for efficient use of scarce resources to target interventions to priority states for the elimination of leprosy in the country.

Neonatal jaundice and its management: knowledge, attitude and practice of community health workers in Nigeria.

BACKGROUND: Neonatal jaundice (NNJ) is still a leading cause of preventable brain damage, physical and mental handicap, and early death among infants in many communities. Greater awareness is needed among all health workers. The objective of the study was to assess the knowledge of primary health care workers about the description, causes, effective treatment, and sequelae of NNJ. METHODS: The setting was a local government area i.e. an administrative district within the south-western part of Nigeria. Community health workers in this area were interviewed by means of a self-administered questionnaire which focused on awareness and knowledge of neonatal jaundice and its causes, treatment and complications. RESULTS: Sixty-six community health workers participated in the survey and male-to-female ratio was 1:5. Their work experience averaged 13.5 (SD 12.7) years. Only 51.5% of the respondents gave a correct definition of NNJ. 75.8 % knew how to examine for this condition while 84.9 % knew at least two of its major causes in our environment. Also, only 54.5 % had adequate knowledge of effective treatment namely, phototherapy and exchange blood transfusion. Rather than referring affected babies to hospitals for proper management, 13.4 %, 10.4 % and 3 % of the participants would treat with ineffective drugs, natural phototherapy and herbal remedies respectively. None of the participants knew any effective means of prevention. CONCLUSION: Primary health care workers may have inadequate knowledge and misconceptions on NNJ which must be addressed concertedly before the impact of the condition on child health and well-being can be significantly reduced. We recommend regular training workshops and seminars for this purpose.

"Near-miss" obstetric events and maternal deaths in Sagamu, Nigeria: a retrospective study.

AIM: To determine the frequency of near-miss (severe acute maternal morbidity) and the nature of near-miss events, and comparatively analysed near-miss morbidities and maternal deaths among pregnant women managed over a 3-year period in a Nigerian tertiary centre. METHODS: Retrospective facility-based review of cases of near-miss and maternal death which occurred between 1 January 2002 and 31 December 2004. Near-miss case definition was based on validated disease-specific criteria, comprising of five diagnostic categories: haemorrhage, hypertensive disorders in pregnancy, dystocia, infection and anaemia. The near-miss morbidities were compared with maternal deaths with respect to demographic features and disease profiles. Mortality indices were determined for various disease processes to appreciate the standard of care provided for life-threatening obstetric conditions. The maternal death to near-miss ratios for the three years were compared to assess the trend in the quality of obstetric care. RESULTS: There were 1501 deliveries, 211 near-miss cases and 44 maternal deaths. The total near-miss events were 242 with a decreasing trend from 2002 to 2004. Demographic features of cases of near-miss and maternal death were comparable. Besides infectious morbidity, the categories of complications responsible for near-misses and maternal deaths followed the same order of decreasing frequency. Hypertensive disorders in pregnancy and haemorrhage were responsible for 61.1% of near-miss cases and 50.0% of maternal deaths. More women died after developing severe morbidity due to uterine rupture and infection, with mortality indices of 37.5% and 28.6%, respectively. Early pregnancy complications and antepartum haemorrhage had the lowest mortality indices. Majority of the cases of near-miss (82.5%) and maternal death (88.6%) were unbooked for antenatal care and delivery in this hospital. Maternal mortality ratio for the period was 2931.4 per 100,000 deliveries. The overall maternal death to near-miss ratio was 1: 4.8 and this remained relatively constant over the 3-year period. CONCLUSION: The quality of care received by critically ill obstetric patients in this centre is suboptimal with no evident changes between 2002 and 2004. Reduction of the present maternal mortality ratio may best be achieved by developing evidence-based protocols and improving the resources for managing severe morbidities due to hypertension and haemorrhage especially in critically ill unbooked patients. Tertiary care hospitals in Nigeria could also benefit from evaluation of their standard of obstetric care by including near-miss investigations in their maternal death enquiries.

Fertility desires and intentions of HIV-positive patients at a suburban specialist center.

OBJECTIVES: To determine the extent of fertility desires and intentions of HIV-positive patients receiving care at a suburban specialist clinic and assess how these may vary by their sociodemographic and health-related factors. METHODS: Questionnaire-based interview of a consecutive sample of HIV-positive men (18-55 years) and HIV-positive women (18-45 years) who presented at the HIV clinic of the Center for Special Studies, Sagamu, Nigeria, between November and December 2004. RESULTS: 63.3% of the 147 studied participants expressed the desire for childbearing, even though 50.4% of them already had > or = 2 children. Respectively, 71.5% and 93.8% of men and women who desired children intended to have > or = 2 in the near future. Only 4.3% of those who desired children did not intend to have any. All 30 individuals who had no children intended to bear children in the future, and they constituted 32.3% of those who expressed the desire for childbearing. Multivariate logistic regression analyses of associated factors indicated that decreasing age, shorter time since diagnosis of HIV infection and nondisclosure of serostatus to current partner significantly increase the odds of desire for childbearing, while having no children and a poor most-recent CD4 count significantly increase the odds of intention to have > or = 3 children instead of 1-2. CONCLUSION: The extent of the fertility desires and intentions of these patients poses a threat to the preventive strategies against vertical and heterosexual transmission of HIV in this region. In view of their compelling desire for parenthood, it may be wise for caregivers to desist from the conventional systematic advice against pregnancy but, in addition to laying emphasis on the risks, provide adequate information on practicable reproductive options for HIV-positive individuals.

Nevirapine-related adverse events in a patient receiving a fixed-drug combination pill.

Nevirapine associated rash has been well described in the Caucasian population. With increasing access to antiretroviral treatment--especially a fixed dose combination--by people living with HIV/AIDS in developing countries, there is a need to emphasize the lead in doses of nevirapine. We strongly recommend a warning label on the bottle advising patients on the lead-in period and the signs and symptoms of significant rash.
