Incidence of Catastrophic Health Expenditures Amongst Hospitalized Neonates in Ekiti, Southwest Nigeria.

Background: Neonatal illnesses require huge spending due to prolonged hospital stay. The management of these illnesses is usually financed by individual families which in most instances are living below the poverty line. This healthcare financing method can readily push families into catastrophic spending on health. Aim: To ascertain the average cost of managing common neonatal illnesses and the financial burden, it constitutes to families in Ekiti State, southwest Nigeria. Methods: We conducted a cross-sectional study on the out-of-pocket spending involved in managing neonates admitted into and discharged from the SCBU of the Ekiti State University Teaching Hospital, Ado-Ekiti, southwest Nigeria. Data collected included the monthly family income, the money spent on drugs, laboratory investigations and the hospital bill using a purposely designed structured questionnaire. Healthcare spending greater than 10% of the overall family income was described as catastrophic health spending (CHS). Results: The medical bills for most (95%) of the 119 study participants were paid through the out-of-pocket means and 81.5% of the families spent more than 10% of their monthly earnings (CHS) to settle medical bills. Close to 50% of the families belonged to the lower social economic class. The median (IQR) duration of hospital stay was 2.75 days (3.0-8.0). The median (IQR) total expenditure was N24,500.00 (N13,615.00-N41,487.50). The median (IQR) expenditure for the treatment of prematurity was highest at N55,075.00 (USD 133.10) [N27,350.00 (USD 66.10)-N105,737.50 (USD 255.53)] and more than 60.5% of the expenses was on hospital utilities and consumables. The length of hospital stay showed a robust positive correlation with the total hospital bill (r = 0.576, P < 0.001). Conclusion: Neonatal illnesses put many households at risk of catastrophic health spending. There is need for increased government investment in health and extension of the health insurance scheme to all the citizens of the country.

Relationship between ultrasound-measured spleen, liver and anthropometry of children living in a rural community in southwest Nigeria: a cross-sectional study.

BACKGROUND: Ultrasonography is noninvasive, relatively inexpensive and useful for resource-poor settings. US spleen and liver sizes have been observed to differ among populations, so there is a need for reference values for different geographic populations. OBJECTIVE: To describe the sizes of the spleen and liver of children living in a rural community in southwest Nigeria and assess the relationship between these measurements and the children's anthropometry. MATERIALS AND METHODS: We conducted a community-based cross-sectional study among 358 apparently healthy children ages 1-14 years. We obtained the participants' weights, heights, body mass index and body surface area. They underwent US imaging to obtain longitudinal measurements of their spleen and liver. We used independent t-test to compare means, and linear regression analysis to assess relationships between continuous data. The significance level was set as P < 0.05. RESULTS: There were more girls (181; 50.6%). Most children were ages 1-5 years (172; 48.0%). The body surface area had significantly strong positive relationships with US spleen size (r = 0.769; R2 = 0.592; P < 0.0001) and US liver size (r = 0.819; R2 = 0.671; P < 0.0001) but body mass index had weak positive relationships. CONCLUSION: This study contributes to data on US spleen and liver sizes of Nigerian children. The findings buttress observations that body surface area strongly correlates with US spleen and liver measurements. It is recommended that more studies be conducted among Nigerian children to generate a robust pool of data that are useful for creating homogeneous formulae to ease interpretation of US measurements of these intraabdominal organs.

Towards malaria control in Nigeria: implications of the malaria parasite rate and spleen rate among children living in a rural community in southwest Nigeria.

BACKGROUND: The World Health Organization prioritizes malaria surveillance for accurate tracking of progress of intervention programmes. The malaria parasite rate (PR) and spleen rate (SR) are economical surveillance tools. There has been a global decline in the burden of malaria over the last decade, but most African countries, like Nigeria, have a slow rate of decline. There is a need for adequate malaria surveillance to guide malaria control strategies and policymaking. METHODS: A community-based cross-sectional study was conducted among 363 children ages 1-15 y in rural southwest Nigeria. The participants' PR was determined by microscopy and the SR was determined by palpation and ultrasonography. The associations between PR and SR and other covariates were assessed. RESULTS: The PR was 26.7% and the SR was 12.9%. There was no significant association between PR or SR across age groups, but low social class was significantly associated with PR (55 [33.5%], p=0.004) and SR (29 [17.3%], p=0.013). The odds of having splenomegaly doubled with malaria parasitaemia (odds ratio 2.03 [95% confidence interval 1.06 to 3.88). CONCLUSIONS: The PR and SR suggest that the study area is meso-endemic. The PR in the study area was almost equal across age groups; our findings suggest there may be a need for policy review to plan malaria intervention programmes and include older children, not just children <5 y of age. Routine malaria surveillance using simple tools such as the PR and SR are necessary for reviewing malaria control programmes in the community.

Diagnostic Accuracy of HemotypeSC as a Point-of-Care Testing Device for Sickle Cell Disease: Findings from a Southwestern State in Nigeria and Implications for Patient Care in Resource-Poor Settings of sub-Saharan Africa.

This study aimed to determine the performance of a rapid, point-of-care testing device (HemotypeSC)™ for diagnosing sickle cell disease (SCD) relative to 2 commonly-used methods compared to DNA polymerase chain reaction (PCR) as the reference standard. The diagnostic performance of (HemotypeSC)™ in diagnosing SCD and determining various other Hb genotypes relative to high performance liquid chromatography (HPLC) and cellulose acetate Hb electrophoresis in alkaline buffer (CAE) was investigated among 156 participants aged 4 to 23 years in Ekiti, Southwest Nigeria. PCR was considered as the reference method/gold standard. The sensitivity and specificity for SS, SC, AS, AC, and AA genotypes by HemotypeSC and HPLC when compared with PCR, were each 100%. Similarly, their positive and negative predictive values were each 100%. However, sensitivity and specificity for identifying these Hb genotypes by CAE were 100, 100, 96.5, 0, 99.2%, and 99, 100, 92.9, 0, 91.7%. Also, CAE did not identify any of the 2 HbAC individuals that were correctly identified by PCR and both HemotypeSC, and HPLC, thus representing 100% HbAC misdiagnosis. In conclusion, this study shows that HemotypeSC has perfect concordance with PCR and 100% accuracy in diagnosing SCD in the population tested. Its ease of use, accuracy and other attributes make it suitable for use in sub-Saharan Africa for rapid determination of Hb genotypes.

Addressing antimicrobial resistance in Nigerian hospitals: exploring physicians prescribing behavior, knowledge, and perception of antimicrobial resistance and stewardship programs.

INTRODUCTION: We assessed the knowledge of, attitude toward antimicrobial resistance (AMR) and practice of antimicrobial stewardship (AMS) among physicians in Nigeria to provide future guidance to the Nigerian National Action Plan for AMR. METHODS: A descriptive cross-sectional questionnaire-based study explored the physicians' self-reported practice of antibiotic prescribing, knowledge, attitude, and practice of AMR and components of ASPs. RESULTS: The majority (217; 67.2%) of respondents prescribed antibiotics daily in their clinical practice AMR was recognized as a global and local problem by 308 (95.4%) and 262 (81.1%) respondents, respectively. Only 91 (28.2%) of respondents have ever heard of antibiotic stewardship. The median AMR knowledge score was 40 (19-45)out of 45while that for ASP was 46.0(32-57) out of 60. There was significant statistical difference between the ASP median scores among the medical specialties category (P value <0.0001) More respondents had good knowledge of AMR than ASPs (82.7% versus 36.5%; p < 0.0001). CONCLUSION: Respondents in this study were more knowledgeable about AMR than AMS and its core components.

Seroprevalence and determinants of Helicobacter pylori infection among asymptomatic under-five children at a Tertiary Hospital in the South-Western region of Nigeria.

BACKGROUND: The epidemiology of Helicobacter pylori (H. pylori) infection among under-five children in the South West Nigeria remains largely understudied. There is no data on the subject from the study area. OBJECTIVES: This study was conducted to assess the seroprevalence of H. pylori infection among under-five children at a tertiary hospital in the South Western, Nigeria and to determine its associated socio-demographic factors. METHODS: Sera of 360 children were analyzed for anti H. pylori Ig G using enzyme linked immunosorbent assay test kit (BQ ELISA Ig G KIT) and H. pylori infection risk factors were determined. Determinants of H. pylori infection was determined using binary logistic regression analysis and p-values < 0.05 were taken as statistically significant. RESULTS: H. pylori infection seroprevalence rate was 32.8% and increased with age. Living in one room accommodation, large families, playing with soil, family history of dyspepsia, practice of premastication, sharing of plates and cutlery, and water closet toilet were associated with H. pylori Ig G seropositivity (p<0.05) on binary regression analysis. CONCLUSION: The seroprevalence of H. pylori infection in under -five children is high, increasing as the age of the children increased. This may suggest that instituting preventive measures at young age, targeting identified factors may be effective in reducing the burden of H. pylori infection.

Influence of alpha thalassemia on clinical and laboratory parameters among nigerian children with sickle cell anemia.

BACKGROUND: There is paucity of data on the influence of alpha thalassemia on the clinical and laboratory parameters among Nigerian sickle cell anemia (SCA) patients. This study aimed to determine the prevalence of alpha thalassemia and the influence of alpha thalassemia on laboratory parameters and clinical manifestations in a group of young Nigerian SCA patients. METHODS: This was a cross-sectional retrospective study conducted on 100 patients with SCA and 63 controls. The diagnosis of SCA was confirmed by DNA studies. Alpha thalassemia genotyping was performed by multiplex gap-PCR method. Laboratory parameters including complete blood count, hemoglobin quantitation, serum lactate dehydrogenase (LDH), and bilirubin were determined with standard techniques. RESULTS: Alpha thalassemia was found in 41 (41.0%) patients compared to 24 (38.1%) controls (P = 0.744), and all were due to the 3.7 κb α-globin gene deletions. Alpha thalassemia was associated with more frequent bone pain crisis, higher hemoglobin concentration, red blood cell count, and HbA2 level among the patients. On the contrary, patients with alpha thalassemia had lower mean corpuscular volume, mean corpuscular hemoglobin, and white blood cell count (WBC) (P Ë‚ 0.05). There were 6 (6.0%) patients with leg ulcers, and none of them had alpha thalassemia, P = 0.04. CONCLUSION: This study confirms that coexistence of alpha thalassemia with SCA significantly influences both the clinical and laboratory manifestations of young Nigerian SCA patients. The coexistence of this genetic modifier is associated with increased bone pain crisis and protects against sickle leg ulcers among the patients.

Preliminary trial of aloe vera gruel on HIV infection.

BACKGROUND: Ten (10) young women diagnosed with human immunodeficiency virus (HIV) infection in the Wesley Guild Hospital Ilesa, a unit of Obafemi Awolowo University Teaching Hospital, Ile Ife, Osun State, Nigeria who did not meet the national criteria for the use of antiretroviral drugs were managed with 30-40 mL of aloe vera (Aloe barbadensis miller) gruel daily. METHODS: Their CD4 counts, general improvement, and physical well-being (including weight gain) were monitored over a 1-year period. The findings were compared with those of 20 age- matched controls who were on antiretroviral drugs. One (1) patient who reacted badly to antiretroviral drug switched over to aloe vera. RESULTS: The average weight gain among those on aloe vera was 4.7 kg compared to 4.8 kg by those on antiretroviral drug (p=0.916). The average rise in CD4 count among them was 153.7 cells/µL compared to 238.85 cells/µL among the controls (p=0.087). There was no significant side effect(s) in either group except in the 1 patient who switched over from antiretroviral drugs to aloe vera gruel. CONCLUSIONS: These preliminary data suggest that consumption of aloe vera may be of help to HIV-infected individuals in the tropics, given its availability and inexpensiveness.
