Immunization status of children 1-5 years old seen at the Emergency Pediatric Unit of a Teaching Hospital in North-Central Nigeria.

Introduction: Advocacy for immunization has been ongoing in various parts of the world to improve immunization uptake amongst children. Annually within the last decade, immunization has been reported to avert over two million deaths globally. This study determined the current immunization status of children 1-5 years of age, the factors affecting immunization uptake and recommends ways of improving immunization uptake among children presenting at an Emergency Pediatric Unit (EPU). Methods: This was a prospective cross-sectional study conducted from 1st October to 30th November 2019. All eligible children aged 1-5 years old seen within the study period whose mothers/caregivers consented to participate in the study were recruited in the EPU of Jos University Teaching Hospital (JUTH), Plateau State, Nigeria. A systematic sampling technique was employed in the selection of caregiver/mother-child pair while data were obtained using an interviewer-administered questionnaire. Results: A total of 191 (76.4%) children were fully immunized for age. Distance to the health facility, experience of vaccine side effects and health workers' attitude were significantly associated with immunization status. Distance to health facility was an independent predictor of complete immunization while short messaging service (SMS) was the most preferred 190 (76.0%) way suggested to improve immunization uptake. Conclusions: This study has brought to light a suboptimal level of full immunization status for age, which can be improved by targeting homegrown interventions at improving accessibility to the facility and addressing adverse events following immunization promptly.

Prevalence of hepatitis B virus infection in pregnant women with and without HIV in Jos, Nigeria.

OBJECTIVE: To compare the prevalence of hepatitis B virus (HBV) in pregnant women with and without human immunodeficiency virus (HIV) in Jos, Nigeria. METHODS: This comparative cross-sectional study of pregnant women was undertaken between 1 November 2017 and 30 April 2018. Informed consent was obtained, demographic data and predictors for HBV were collected, and all women were screened for HIV and HBV. Descriptive statistics and multivariate analyses using STATA Version 15 were performed. RESULTS: Of 3238 women enrolled, 12.6% and 7.2% of those with and without HIV had HBV, respectively (P = 0.01). Women with HIV, higher parity [adjusted odds ratio (aOR) 0.68, P < 0.01], lower gestational age (aOR 1.04, P < 0.01) and without prior HBV vaccination (aOR 0.40, P < 0.01) were significantly more likely to have HBV infection. CONCLUSIONS: Among pregnant women, the prevalence of HBV was higher among those with HIV. Predictors of HBV included being multigravida or grand-multigravida, registration for antenatal care before 20 weeks of gestation, and no prior HBV vaccination. In settings with endemic HBV and HIV, integration of effective HBV and HIV prevention services could greatly decrease the transmission and prevalence of HBV.

Prevalence of hepatitis B virus infection among pregnant women in Jos, Nigeria.

Objectives: The study sought to determine the prevalence and risk factors associated with Hepatitis B surface antigenemia (HBsAg) positivity among pregnant women in Jos, Nigeria. Methodology: This was a cross-sectional study carried out among the pregnant population in five healthcare facilities in Jos, between November 1, 2017 and April 30, 2018. Informed consent was obtained, and data on sociodemographic and risk factors for hepatitis B virus (HBV) infection were collected. Hepatitis B viral infection was assessed using the in vitro HBsAg diagnostic rapid kit (Acon Laboratories, USA). Descriptive statistics, Chi-square test, and logistic regression were performed to identify predictors of HBV infection in the study population. All statistical analyses were carried out on STATA version 15. Results: Of the 3,238 women enrolled, 7.4% (241/3238) (95% confidence interval [CI] = 6.6% to 8.4%) were HBsAg positive. The absence of HBV vaccination (adjusted odds ratio [AOR] = 2.49; 95% CI = 1.49-4.09; P < 0.001), co-infection with HIV (AOR = 1.90; 95% CI = 1.18-3.08; P = 0.009), and higher parity (AOR = 1.37; 95% CI = 1.04-1.79; P = 0.024) were independently associated with HBV infection in pregnancy. Conclusions: The prevalence of HBV infection among pregnant women was high, especially among those without prior vaccination for HBV, those with HIV co-infection and higher parity.

L'absence de vaccination contre le VHB (cotes ajustées rapport [AOR] = 2,49; IC à 95% = 1,49­4,09; P <0,001), co-infection par le VIH (AOR = 1,90; IC à 95% = 1,18­3,08; P = 0,009) et plus la parité (AOR = 1,37; IC à 95% = 1,04-1,79; P = 0,024) était indépendamment associée à l'infection par le VHB pendant la grossesse. Conclusions: le la prévalence de l'infection par le VHB était élevée chez les femmes enceintes, en particulier chez celles qui n'avaient pas été vaccinées contre le VHB, celles avec le VIH co-infection et parité plus élevée.

Improving the diagnosis of pulmonary tuberculosis using line probe assay and determining the factors associated with the disease in children in Jos, Nigeria.

INTRODUCTION: Diagnosing tuberculosis (TB), including pulmonary tuberculosis (PTB), in children remains a challenge, partly due to its paucibacillary nature in young children. Data on the use of line probe assay (LPA), on gastric and sputum samples, for diagnosing PTB in children are scarce. We determined the proportion of samples positive for Mycobacterium tuberculosis (MTB) by smear microscopy (SM) and LPA in presumptive PTB cases as well as the factors associated with PTB confirmed by LPA, in children in Jos, Nigeria. METHODS: An observational study in children aged 6 months-16 years. Gastric and sputum samples were examined by SM and by LPA for MTB using GenoType MTBDRplus Ver 2.0 (Hain Lifescience). Multivariate logistic regression was performed to determine the factors associated with PTB. RESULTS: Out of 103 children with presumptive PTB, 47 had confirmed PTB, 26 unconfirmed PTB and 30 unlikely PTB by LPA. In 67 gastric samples, MTB was identified by SM in 2 (3.0%) compared to 28 (41.8%) by LPA while in 31 sputum samples, MTB was identified by SM in 5 (16.1%) compared to 18 (58.1%) by LPA. The factors associated with pulmonary tuberculosis were an abnormal chest X-ray (adjusted odds ratio (AOR))=12.39 [3.75-40.90], p<0.001), sleeping in the same room with more than three persons (AOR=3.30 [1.23-8.85], p=0.018) and sleeping in a room with none or one window (AOR=2.86 [1.03-7.95], p=0.044). CONCLUSIONS: Line probe assay improves the diagnosis of pulmonary TB in children, especially with gastric samples, while an abnormal chest X-ray is a useful adjunct in PTB diagnosis. Avoiding overcrowding and having windows in sleeping rooms are a necessary part of TB prevention.

Serum lipid and glucose profiles in HIV-positive Nigerian children.

OBJECTIVES: To describe the fasting serum lipid and glucose profiles of HIV-positive Nigerian children and determine the prevalence and risk factors for dyslipidaemia and hyperglycaemia, which are risk factors for cardiovascular diseases. METHODS: This was a comparative cross-sectional study carried out at the Paediatric Infectious Disease Clinic (PIDC) of the Jos University Teaching Hospital (JUTH) for HIV-positive children and at two primary schools in Jos for HIV-negative children as controls. One hundred and forty-two HIV-positive children aged 6-18 years and an equal number of controls were studied by determining their fasting serum lipid and glucose levels. The prevalence of dyslipidaemia and hyperglycaemia was determined and their risk factors obtained using multivariate logistic regression. P values of less than 0.05 were considered statistically significant. RESULTS: Mean triglyceride levels were significantly higher in HIV-positive children compared with controls at 87.2 mg/dL (95% confidence interval [CI] 79.4-95.0) and 68.1 mg/dL (95% CI 62.5-72.7), respectively (P<0.001). There were no significant differences in mean glucose levels. Dyslipidaemia was significantly higher in HIV-positive children (21.8%) compared with controls (12.7%; P=0.04). Total serum cholesterol was elevated in 17 (12.0%) HIV-positive participants compared with seven (4.9%) of controls (P=0.02). Children on lopinavir/ritonavir (LPV/r) and those with no significant or mild disease had a significantly higher prevalence of hypercholesterolaemia (33.3% vs 4.8% and 14.5% vs 0.0%, respectively; P<0.001). CONCLUSION: HIV-positive children on antiretroviral (ARV) drugs, especially LPV/r, should have their lipids regularly monitored as those with dyslipidaemia stand the risk of subsequently developing cardiovascular diseases.

Factors associated with antiretroviral treatment interruption in human immunodeficiency virus (HIV)-1-infected children attending the Jos University Teaching Hospital, Jos, Nigeria.

BACKGROUND: Interrupting anti-retroviral therapy (ART) for any number of reasons is an indication of a compromised adherence to ART. Several factors, including the pill burden from other drugs used in treating co-infections in children with human immunodeficiency virus (HIV), may influence ART adherence. The aim of this study was to identify the factors associated with ART interruption in HIV-1-infected children. MATERIALS AND METHODS: A retrospective cohort study analysing data on 580 children consecutively enrolled on ART between February 2006 and December 2010 at the paediatric HIV clinic of Jos University Teaching Hospital (JUTH), Jos. Subjects were children aged 2 months - 15 years diagnosed with HIV-1 infection and on first-line ART. Cotrimoxazole prophylaxis was usually commenced at diagnosis while awaiting ART commencement. Children diagnosed with tuberculosis (TB) were also placed on multiple individual anti-TB drugs. STATISTICAL ANALYSIS USED: A comparison of the data on children with and without ART interruption was made. Variables associated with ART interruption in a univariate analysis were fit in a multivariate logistic model to determine the factors that were associated with ART interruption. RESULTS: Children on anti-TB drugs were twice more likely to interrupt ART compared to those who were not, (adjusted odds ratio, AOR = 1.84 (1.03-3.28); P = 0.04). But children on cotrimoxazole prophylaxis had a 57% reduction in the odds of interrupting ART compared to those who were not, (AOR = 0.43 (0.20-0.93); P = 0.03). CONCLUSION: Children on ART and also taking multiple individual anti-TB drugs should be monitored closely for ART adherence. Cotrimoxazole prophylaxis should be encouraged in children diagnosed with HIV while awaiting ART commencement as this may prime them for a better ART adherence.
