Heart failure in Nigeria: protocol for a systematic review and meta-analysis.

Background: Heart failure is now a significant contributor to the burden of non-communicable diseases in developing countries like Nigeria which is experiencing epidemiologic and demographic transition. The epidemiology of heart failure in this country is poorly characterized. The aim of the review is to determine the prevalence of heart failure, the associated risk factors, the aetiology, management, and outcomes of the condition in the country. Methods: Relevant databases such as PubMed /Medline, EMBASE, Web of Science, Google Scholar, African Index Medicus, and African journal online would be searched for articles published in English from January 2000 to December 2021. The analysis will include observational studies conducted among Nigerian adults aged 12 years and above. Article selection shall be conducted by pairs of independent reviewers. Data extraction shall be done by 2 independent reviewers. Results: The primary outcome would be the pooled prevalence of heart failure while the secondary outcomes would be to identify the risk factors and management of heart failure in Nigeria. Conclusion: This will be the first systematic review and meta-analysis of heart failure epidemiology in Nigeria which will hopefully identify gaps for future research and guidance for policy interventions.

Neonatal Jaundice: Perception of Pregnant Women Attending Antenatal Clinic at a Tertiary Hospital in Southwest, Nigeria.

Background: Severe neonatal jaundice (NNJ) remains a leading cause of preventable brain damage, mental handicap, physical disabilities, and early death among infants. Methods: Using a descriptive cross-sectional study design, information was gathered using a structured, pretested questionnaire from 518 pregnant women who attended the antenatal clinic at a tertiary Hospital in Southwest Nigeria. Results: Most (77%) of the respondents have heard about NNJ prior the survey. Most respondents (69.5%) demonstrated poor knowledge of the causes of NNJ. The majority, 98.4% had good attitude toward treatment of NNJ. Most respondents (72.1%) demonstrated poor knowledge of the correct treatment of NNJ. A quarter of the respondents knew no danger sign of NNJ. Conclusion: There is serious knowledge gap among the respondents about the causes, treatment, dangers signs and complications of NNJ. There is need for increased awareness campaign using every available means of reaching women of reproductive age group to reduce the consequences of this common neonatal problem.

Pattern and outcome of dog bite injuries among children in Ado-Ekiti, Southwest Nigeria.

INTRODUCTION: Dog bites in humans are a major public health problem. Globally, millions of people are bitten by dogs but most of the fatal cases occur in children. There is paucity of data on dog bite related diseases among Nigerian children. Objectives: to determine the pattern of dog bite injuries and associated health problems among children seen at Ekiti State University Teaching Hospital. METHODS: This is a retrospective study on the clinical data of patients managed for dog bite related injuries between January 2010 and June 2014. RESULTS: In all, 84 cases of dog bite injuries were managed constituting 0.89% of the total consultations; six (7.1%) had rabies. Most of the victims were aged 6-12 years (60.7%) and majority (71.4%) was boys. Eighty two percent of the victims presented within 24hrs of the injury. Thirty-six (43%) had WHO grade 3 dog bite injury at presentation and the lower limb was the commonest (57.1%) bite site. Use of herbal preparation was the most common pre-hospital treatment 60%. Although 92.9% received anti-rabies vaccine, only 64.3% of them completed the vaccination schedule. The case fatality rate for dog bite was 7.14%. The six that died all presented late, had no post exposure prophylaxis and died within 24 hours of admission. CONCLUSION: There is need for public enlightenment on dangers associated with dog bites and also for the government to defray the high cost of post exposure prophylaxis treatment for children.

Prescription audit in a paediatric sickle cell clinic in South-West Nigeria: A cross-sectional retrospective study.

Background: Sickle cell disease (SCD) is a genetic haematological disorder that affects millions of people around the world especially people of African heritage. The treatment of the symptoms of SCD includes the use of analgesics, antibiotics, and anti-malarial drugs. Studying the pattern of drug prescription is a veritable tool for establishing the current practice and how it conforms to existing guidelines. Objectives: The main objective of this study was to assess the pattern of drug prescription in children with sickle cell disease (SCD) attending the paediatric outpatients' clinic of a tertiary care centre in Ado-Ekiti, South-West Nigeria. Methods: This was a cross-sectional retrospective study carried out using the medical records of all patients with SCD who attended the paediatric outpatient clinic of the teaching hospital between January 1 and December 31, 2014. The information retrieved from the case notes included the bio-demographic data, associated co-morbid conditions and the list of prescribed drugs. Results: A total of 202 SCD patients aged below 18 years were seen in the clinic during the study period with males accounting for 61.9% of them. The mean age of all patients was 6.9 ±3.8 yrs. A total of 1015 medications were prescribed during the study period giving a mean of 5.02 ± 1.9. Vitamins/micronutrients, anti-malarial drugs, antibiotics and analgesics accounted for 41.4%, 29.0%, 15.7% and 13.9% of all prescribed drugs respectively. Antibiotics from the penicillin group were the most commonly prescribed followed by macrolides and cephalosporins while Ibuprofen (60.3%) and Acetaminophen (32.6%) were the commonly prescribed analgesics. Conclusion: High rate of antibiotic prescription, low use of opioid analgesics and non-prescription of prophylactic penicillin/pneumococcal vaccination were the main findings in this study. There is need for the introduction of standard treatment protocols for this group of patients.

Point-of-Care Testing for Anaemia in Children Using Portable Haematocrit Meter: A Pilot Study from Southwest Nigeria and Implications for Developing Countries.

BACKGROUND: Prompt and accurate diagnosis is needed to prevent the untoward effects of anaemia on children. Although haematology analyzers are the gold standard for accurate measurement of haemoglobin or haematocrit for anaemia diagnosis, they are often out of the reach of most health facilities in resource-poor settings thus creating a care gap. We conducted this study to examine the agreement between a point-of-care device and haematology analyzer in determining the haematocrit levels in children and to determine its usefulness in diagnosing anaemia in resource-poor settings. METHODS: EDTA blood samples collected from participants were processed to estimate their haematocrits using the two devices (Mindray BC-3600 haematology analyzer and Portable Mission Hb/Haemotocrit testing system). A pairwise t-test was used to compare the haematocrit (PCV) results from the automated haematology analyzer and the portable haematocrit meter. The agreement between the two sets of measurements was assessed using the Bland and Altman method where the mean, standard deviation and limit of agreement of paired results were calculated. RESULTS: The intraclass and concordance correlation coefficients were 0.966 and 0.936. Sensitivity and specificity were 97.85% and 94.51% respectively while the positive predictive and negative predictive values were 94.79% and 97.73%. The Bland and Altman`s limit of agreement was -5.5-5.1 with the mean difference being -0.20 and a non-ignificant variability between the two measurements (p = 0.506). CONCLUSION: Haematocrit determined by the portable testing system is comparable to that determined by the haematology analyzer. We therefore recommend its use as a point-of-care device for determining haematocrit in resource-poor settings where haematology analyzers are not available.

Evaluation of a Portable Haemoglobin Metre Performance in Children with Sickle Cell Disease and Implications for Healthcare in Resource-poor Settings.

BACKGROUND: Sub-Saharan Africa has the largest burden and worst outcome of sickle cell disease (SCD). This gloomy outlook has been attributed to the lack of use of simple and cost-effective measures for diagnosis and treatment of the disease. Although haematology analysers are the gold standard for accurate measurement of haemoglobin (Hb) concentration, they are often out of reach of most health facilities in resource-poor settings, thus creating a care gap. We conducted this study to examine the agreement between a point-of-care device and haematology analyser for determining the Hb concentration in children with SCD and its usefulness in resource-poor settings. METHODS: Ethylenediaminetetraacetic acid blood samples collected from participants were processed to estimate their Hb concentration using two devices (Sysmex KX21N haematology analyser and portable mission Hb device). The agreement between the two sets of measurements was assessed by the Bland and Altman method. RESULTS: The intraclass and concordance correlation coefficients were 0.854 and 0.936, respectively. Sensitivity and specificity were 84.2% and 98.6%, respectively. The positive and negative predictive values were 94.1% and 96.0%, respectively. The Bland and Altman's limit of agreement was -2.3 to 1.6 and the mean difference was -0.34 with non-significant variability between the two measurements (p = 0.949). CONCLUSION: Hb concentration determined by the portable testing system is comparable with that determined by the haematology analyser. We recommend its use as a point-of-care device for determining Hb concentration of SCD children in resource-poor settings where haematology analysers are not available.

The financial burden of sickle cell disease on households in Ekiti, Southwest Nigeria.

BACKGROUND: Studies on economic impact of sickle cell disease (SCD) are scanty despite its being common among children in developing countries who are mostly Africans. OBJECTIVE: To determine the financial burden of SCD on households in Ado Ekiti, Southwest Nigeria. METHODS: A longitudinal and descriptive study of household expenditures on care of 111 children with SCD managed at the pediatric hematology unit of the Ekiti State University Teaching Hospital was conducted between January and December 2014. RESULTS: There were 64 male and 47 female children involved, aged between 15 and 180 months. They were from 111 households, out of which only eight (7.2%) were enrolled under the National Health Insurance Scheme. The number of admissions and outpatients' consultations ranged from 1 to 5 and 1 to 10 per child, respectively. Malaria, vaso-occlusive crisis, and severe anemia were the leading comorbidities. The monthly household income ranged between ₦12,500 and ₦330,000 (US$76 and US$2,000) with a median of ₦55,000 (US$333), and health expenditure ranged between ₦2,500 and ₦215,000 (US$15 and US$1,303) with a mean of ₦39,554±35,479 (US$240±215). Parents of 63 children lost between 1 and 48 working days due to their children's ill health. Parents of 23 children took loans ranging between ₦6,500 and ₦150,000 (US$39 and US$909) to offset hospital bills. The percentage of family income spent as health expenditure on each child ranged from 0.38 to 34.4. Catastrophic health expenditure (when the health expenditure >10% of family income) occurred in 23 (20.7%) households. Parents who took loan to offset hospital bills, low social class, and patients who took ill during the study period significantly had higher odds for catastrophic health expenditure (95% confidence interval [CI] 5.399-87.176, P=0.000; 95% CI 2.322-47.310, P=0.002; and 95% CI 1.128-29.694, P=0.035, respectively). CONCLUSION: SCD poses enormous financial burden on parents and households.
