ABSTRACT

BACKGROUND AND OBJECTIVE: The impact of allergic rhinitis (AR), a common comorbidity in asthma, on global quality of life (QoL) using generic QoL questionnaires has not been extensively evaluated. METHODS: This was a cross-sectional population-based study among adults ≥18 years old. Generic QoL was measured using the World Health Organization (WHO) questionnaire (WHOQOL-BREF), and asthma control was assessed using the Asthma Control Test. Participants were categorized into four groups: Group 1 (No asthma, no AR), Group 2 (Asthma only), Group 3 (AR only) and Group 4 (Concomitant asthma and AR). The student t-test or the ANOVA was used for comparison between groups and based on the level of asthma control. Linear regression was used to assess the association between the level of asthma control and QoL scores, adjusted for age and sex. A p-value of less than 0.05 was considered significant for all associations. RESULTS: There were 9115 participants; 906 (9.9%) had asthma, and 1998 (21.9%) had AR. The lowest QoL scores were in the environment domain. Mean QoL scores were significantly lower in asthma compared to 'no asthma' and in AR compared to 'no AR'. Either asthma or rhinitis (Group 2 or 3) had significantly lower scores compared to no disease (Group 1) only in the environment domain, but the concomitant disease (Group 4) had lower scores across all categories and domains. Scores were significantly lower for uncontrolled asthma compared to controlled asthma and for 'concomitant asthma and AR' compared to 'asthma only'. Increasing age and uncontrolled asthma predicted worse health-related quality of life (HRQoL) consistently. CONCLUSION: Although asthma and AR negatively impact HRQoL independently, concomitant asthma and AR are worse. Uncontrolled asthma underpins poor QoL in asthma because QoL is not impaired in controlled disease. This underscores the need for recognition and treatment of AR in asthma and reinforces the benefits of achieving asthma control as a priority in asthma treatment.

ABSTRACT

BACKGROUND: This study aimed to evaluate the safety and effectiveness of the BNT162b2 vaccine in immunocompromised adolescents and young adults. RESEARCH DESIGN AND METHODS: The study conducted a meta-analysis of post-marketing studies examining BNT162b2 vaccination efficacy and safety among immunocompromised adolescents and young adults worldwide. The review included nine studies and 513 individuals aged between 12 and 24.3 years. The study used a random effect model to estimate pooled proportions, log relative risk, and mean difference, and assessed heterogeneity using the I2 test. The study also examined publication bias using Egger's regression and Begg's rank correlation and assessed bias risk using ROBINS-I. RESULTS: The pooled proportions of combined local and systemic reactions after the first and second doses were 30% and 32%, respectively. Adverse events following immunization (AEFI) were most frequent in rheumatic diseases (40%) and least frequent in cystic fibrosis (27%), although hospitalizations for AEFIs were rare. The pooled estimations did not show a statistically significant difference between immunocompromised individuals and healthy controls for neutralizing antibodies, measured IgG, or vaccine effectiveness after the primary dose. However, the evidence quality is low to moderate due to a high risk of bias, and no study could rule out the risk of selection bias, ascertainment bias, or selective outcome reporting. CONCLUSIONS: This study provides preliminary evidence that the BNT162b2 vaccine is safe and effective in immunocompromised adolescents and young adults, but with low to moderate evidence quality due to bias risk. The study calls for improved methodological quality in studies involving specific populations.

ABSTRACT

Background: The burden of tuberculosis (TB) in Nigeria remains high, and diagnosis in children, a challenge. We aimed to document yield from Xpert Mycobacterium tuberculosis/rifampicin (MTB/RIF) as a mode of diagnosis for children and the variables associated with a positive result. Methods: This was a retrospective review of TB treatment cards of children aged 0-15 years managed from January 2017 to December 2021 across six public tertiary institutions in Nigeria. The data obtained were analyzed using the descriptive and inferential statistics. Statistical significance was set at P < 0.05. Results: Of 1489 children commenced on TB treatment, 1463 (97.9%) had sufficient data for analysis the median age of study participants was 60 months (interquartile range [IQR]: 24, 120), and 814 (55.6%) were males. Xpert MTB/RIF test was performed in 862 (59%) participants and MTB was detected in 171 (19.8%) participants, of which 6.4% (11/171) had RIF resistance reported. The use of Xpert MTB/RIF rose from 56.5% in 2017 to 64% in 2020 but fell to 60.9% in 2021. We found that older age (> 10 years), the presence of pulmonary TB (PTB), and a negative human immunodeficiency virus (HIV) status were associated with positive Xpert MTB/RIF tests (P = 0.002, 0.001, and 0.012, respectively). Conclusion: The utilization of Xpert MTB/RIF in children increased in the years before the COVID-19 pandemic. Factors associated with MTB detection by Xpert MTB/RIF include older age, the presence of PTB, and a negative HIV status. Clinical and radiological evaluation continues to play vital roles in the diagnosis of childhood TB in Nigeria.

ABSTRACT

BACKGROUND: Several studies have shown that the impact of maternal mental health disorders on newborns' well-being in low and middle-income countries (LMIC) are underreported, multi-dimensional and varies over time and differs from what is reported in high-income countries. We present the prevalence and risk factors associated with common mental disorders (CMDs) among breastfeeding mothers whose infants were admitted to Nigerian tertiary care facilities. METHODS: This was a national cross-sectional study involving mothers of hospitalised babies from eleven Nigerian tertiary hospitals. We used the WHO self-reporting Questionnaire 20 and an adapted WHO/UNICEF ten-step breastfeeding support package to assess mothers' mental health and breastfeeding support. RESULTS: Only 895 of the 1,120 mothers recruited from eleven tertiary healthcare nurseries in six geopolitical zones of Nigeria had complete datasets for analysis. The participants' mean age was 29.9 ± 6.2 years. One in four had CMDs; 24.0% (95% CI: 21.235, 26.937%). The ages of mothers, parity, gestational age at delivery, and length of hospital stay were comparable between mothers with and those without CMDs. Antenatal care at primary healthcare facilities (adjusted odds ratio [aOR:13], primary education [aOR:3.255] living in the south-southern region of the country [aOR 2.207], poor breastfeeding support [aOR:1.467], polygamous family settings [aOR:2.182], and a previous history of mental health disorders [aOR:4.684] were significantly associated with CMDs. In contrast, those from the middle and lower socioeconomic classes were less likely to develop CMDs, with [aOR:0.532] and [aOR:0.493], respectively. CONCLUSION: In Nigeria, the prevalence of CMDs is relatively high among breastfeeding mothers with infants admitted to a tertiary care facility. Prior history of mental illness, polygamous households, mothers living in the southern region and low or no educational attainment have a greater risk of developing CMDs. This study provides evidence for assessing and tailoring interventions to CMDs among breastfeeding mothers in neonatal nurseries in LMIC.

ABSTRACT

Introduction: the high expectations that heralded the development of COVID-19 vaccines has been plagued with vaccine hesitancy (VH). The prevalence and associated factors of COVID-19 VH in the six geopolitical zones in Nigeria are explored. Methods: using a cross sectional survey, a pre-tested and validated questionnaire on a "Google form" was distributed via social media platforms and hard copies in the six geopolitical zones of Nigeria. Included, using a chain-reference sampling technique, were healthcare workers (HCW), university students and adults in the general population. Participants who expressed unwillingness to receive COVID-19 vaccine in the event of an available vaccine were considered to have vaccine hesitancy. Frequency and percentage were used to describe categorical variables. Multivariable logistic regression analysis was used to assess for factors associated with VH. Level of significance was set at 5% on two-sided tails test. Results: among 1615 respondents, mean (standard deviation) age was 36.7 (11.3) years, and 847 (52.4%) were males. More than half were healthcare workers (943; 58.4%), 97.4% had at least secondary level of education, and majority 60.5% belonged to the upper social class. The prevalence of VH was 68.5% (1107/1615), and 67.2% preferred foreign manufactured COVID-19 vaccines. On multivariable regression analysis, residence in Northeast (AOR 6.01, 95% CI 2.24, 16.10) and Northwest (AOR 3.33, 95% CI 1, 48, 7.48) geopolitical zones, the Igbo ethnic group (AOR 1.88, 95% 1.10, 3.22), Christians (AOR 1.86, 95% 1.10, 3.14), nurses (AOR 3.50, 95% CI 1.25, 9.80), pharmacist (AOR 5.82, 95% CI 2.12, 16.32) and participants without confidence in foreign vaccines (AOR 4.13, 95% CI 2.99, 5.72) were at higher likelihood of VH. Conclusion: vaccine hesitancy is high among adults in Nigeria, with higher likelihood among the Igbo ethnic group, Christian faith, residence in Northeast and Northwest geopolitical zones and those with an aversion to foreign-made vaccines. Targeted interventions are required for the desired COVID-19 vaccine uptake rate and herd immunity.

ABSTRACT

Background: Although several randomized controlled trials (RCTs) published over the past 5 years show that prenatal or postnatal probiotics may prevent or optimize the treatment of childhood asthma and atopic disorders, findings from the systematic reviews and meta-analyses of these studies appear inconsistent. More recent RCTs have focused on postnatal probiotics, and linked specific probiotic strains to better disease outcomes. Objective: This systematic review aimed to determine if postnatal probiotics are as effective as prenatal probiotics in preventing or treating childhood asthma and atopic disorders. Methods: We searched the PubMed, Medline, Google Scholar, and EMBASE databases for RCTs published within the past 5 years (from 2017 to 2022). We included only full-text RCTs on human subjects published in or translated into the English language. We retrieved relevant data items with a preconceived data-extraction form and assessed the methodological quality of the selected RCTs using the Cochrane Collaboration's tool for assessing the risk of bias in randomized trials. We qualitatively synthesized the retrieved data to determine any significant differences in study endpoints of the probiotic and placebo groups. Results: A total of 1,320 participants (688 and 632 in the probiotic and placebo groups) from six RCTs were investigated. One RCT showed that early Lactobacillus rhamnosus GG (LGG) led to a reduction in the cumulative incidence rate of asthma. Another study demonstrated that mixed strains of Lactobacillus paracasei and Lactobacillus fermentum could support clinical improvement in children with asthma while one trial reported a significant reduction in the frequency of asthma exacerbations using a mixture of Ligilactobacillus salivarius and Bifidobacterium breve. Three trials showed that a combination of LGG and Bifidobacterium animalis subsp lactis, Lactobacillus rhamnosus alone, and a probiotic mixture of Lactobacillus LOCK strains improved clinical outcomes in children with atopic dermatitis and cow-milk protein allergy. Conclusions: Postnatal strain-specific probiotics (in single or mixed forms) are beneficial in preventing and treating atopic dermatitis and other allergies. Similarly, specific strains are more effective in preventing asthma or improving asthma outcomes. We recommend more interventional studies to establish the most useful probiotic strain in these allergic diseases.

ABSTRACT

Bronchiectasis (BE) is a chronic condition affecting the bronchial tree. It is characterized by the dilatation of large and medium-sized airways, secondary to damage of the underlying bronchial wall structural elements and accompanied by the clinical picture of recurrent or persistent cough. Despite an increased awareness of childhood BE, there is still a paucity of data on the epidemiology, pathophysiological phenotypes, diagnosis, management, and outcomes in Africa where the prevalence is mostly unmeasured, and likely to be higher than high-income countries. Diagnostic pathways and management principles have largely been extrapolated from approaches in adults and children in high-income countries or from data in children with cystic fibrosis. Here we provide an overview of pediatric BE in Africa, highlighting risk factors, diagnostic and management challenges, need for a global approach to addressing key research gaps, and recommendations for practitioners working in Africa.

ABSTRACT

BACKGROUND: Lung function abnormalities may occur in children with human immunodeficiency virus (HIV) infection. Small-airway disease (SAD) precedes abnormalities in forced expiratory volume in 1 s (FEV 1). OBJECTIVE: This study aims to assess the presence and reversibility of SAD in HIV-infected children using the Global Lung Function Initiative standards. METHODS: A cross-sectional study was conducted over 6 months at the Paediatric HIV Clinic of the University of Nigeria Teaching Hospital in Enugu, Southeast Nigeria. Eligible consenting children with HIV infection were recruited. Lung function was measured, and the reversibility of FEV1 and forced vital capacity (FVC) was assessed at 12% while that of forced expiratory flow between 25% and 75% (FEF25-75) was assessed at 12%, 15%, and 20%. Predictors of abnormal Z-score values were determined by multivariate linear and logistic regressions. Statistically significant values were set at P < 0.05. RESULTS: The mean Z-score for FEV1, FVC, and FEF25-75 was - 2.19, -1.86, and - 1.60, respectively. Most patients (73%) had abnormal FEV1, while 52% had abnormal FEF25-75. Significant changes in FEV1 (P = 0.001) and FEF25-75 (P < 0.001) occurred after the bronchodilator response (BDR) test. Of the children whose FEV1 showed positive BDR, 70.9% had low zFEV1; 50% had low zFEF25-75, while all had low FEV1. Nutritional status (Z-score for body mass index) was significantly associated with low FEV1. CONCLUSIONS: Abnormal FEF25-75 as a marker of SAD and FEV1 with a positive BDR are common in HIV-infected children. These lung function abnormalities justify long-term follow-up for these patients.

ABSTRACT

BACKGROUND: There is paucity of data on objectively measured lung function abnormalities in Nigerian children using diagnostic testing methods such as spirometry. Such assessments could prompt early diagnosis and therapeutic interventions. METHODS: This was a cross sectional study among children aged 6 to 12 years in South-Eastern Nigeria. We selected participants from one school using a multistage stratified random sampling technique. A structured respiratory questionnaire was administered to obtain necessary data. The lung functions of the children were measured by spirometry. We used Lower Limits of Normal (LLN) based on GLI reference equations for African-American and mixed ethnicities to define abnormal spirometry. We studied the association between the exposures and lung function using logistic regression/chi-squared tests. RESULTS: A total of 145 children performed acceptable and repeatable tests. There were 73 males (50.3%), mean age of 9.13 years (+1.5) and age range 6 to 12 years. Frequency of respiratory symptoms was cough- 64 (44.1%) and wheeze in 19 (13.1%). Using GLI for African-Americans, fifty-five (37.9%) children had abnormal spirometryobstructive pattern in 40 (27.6%) and restrictive pattern in 15 (10.3%). The two references showed significant differences in interpretation of abnormality (χ2 = 72.86; P < .001). Respiratory symptom-wheeze was an independent determinant of abnormal lung function in this population.(OR = 0.31; 95%CI: 0.10-0.94; P = .04). CONCLUSION: There is a high burden of respiratory symptoms and abnormal spirometry among these children. The need for objective evaluation of lung function especially for children with respiratory symptoms is evident.

ABSTRACT

BACKGROUND: Beyond its chronicity, childhood asthma carries an economic burden for households. In this study we evaluated the cost of care of childhood asthma in a Nigerian household. METHODS: A cross-sectional hospital-based study. Relevant information was obtained through an interviewer-administered questionnaire. The cost of asthma treatment was estimated using direct medical costs and loss in productivity. Data analysis was done with SPSS version 22. A significant value of p < 0.05 was used. RESULTS: Sixty-six participants were enrolled, mean ±â€¯SD age (11.6 ±â€¯) the average direct cost was USD10.35. The cost of drug was USD5.8 and accounted for 56% of the direct cost. The loss in productivity was USD16.73. The mean cost per clinic visit was USD27.08, which was catastrophic in 12 (18.2%) households. The calculated annual cost of asthma treatment was USD162.49, with a cumulative national cost of USD 0.16 billion, which makes up 0.002% of the national GDP. CONCLUSION: The cost burden of asthma treatment may be low on the households but carries a huge national cost impact. We recommend the inclusion of asthma care in the Nigerian social health insurance as this may help reduce the financial burden due to asthma.

ABSTRACT

BACKGROUND: Global standards require that spirometry should be performed by trained and experienced personnel, who would be able to assess the correct performance of tests by patients and assure good quality of the result. The complete achievement of this requires a two-step assessment where competency in both knowledge and skills are tested. This study aims to assess the impact of a one-day hands-on spirometry training (Phase1), on the knowledge and application of spirometry among health workers. METHODS: This was a descriptive cross-sectional study, which describes a one-day (seven hours) spirometry training and skills impartation done at two conference city locations in Enugu and Calabar in the southern part of Nigeria. All the verbally consenting attendees who completed the training assessment tests constituted the study population. The assessment of the spirometry knowledge base before and after the theory and practical sessions, on the various aspects of spirometry, according to international best practices, quality assurance and the interpretation of results, was done and the outcome was analyzed. Factors that could affect the outcome were also assessed. RESULTS: There were 64 consenting participants of whom 54.7% (35/64) were females. Theparticipants demonstrated much improved post-intervention knowledge and could satisfactorily perform spirometry, calibration, interpretation of test results and quality control as evidenced by the post test scores after practical sessions were conducted. Pre-test mean scores improved by a mean difference of 12% (p < 001) and were affected by the year of academic graduation and availability of spirometers at the place of work, an effect that was no longer seen at post-test following the hands-on spirometry training. CONCLUSION: The present study has shown that a one-day spirometry workshop significantly improved the knowledge of spirometry practice. There is need to set up more frequent locally-organized spirometry workshops since a one-day seven-hour effective knowledge and practical training would most likely have significant impact on participants' spirometry practice with its expected positive outcome on respiratory health in Nigeria.

ABSTRACT

ABSTRACT Introduction: Persistent hematuria is a chronic complication of sickle cell anemia (SCA) which can progress to chronic kidney disease. The practice of early detection of persistent hematuria in children with SCA in steady state is important for timely intervention. Objective: To determine the prevalence of persistent hematuria among children with sickle cell anemia in steady state and compare the result with that of a group of HbAA controls. The outcome will possibly strengthen the health policy on the need for regular screening for persistent hematuria in children with SCA. Methods: Children with sickle cell anemia, aged 2-18 years in steady state, were recruited consecutively from the sickle cell clinic at the University of Nigeria teaching Hospital Enugu. The controls were similarly recruited from the children's outpatient clinic. To determine persistent hematuria, dipstick urinalysis and microscopy were performed for both subjects and controls at enrollment and repeated after four weeks. Results: Out of the 122 children with SCA studied, 5 (4.1%) had persistent hematuria. None (0%) of the 122 age- and gender-matched HbAA controls had persistent hematuria. This difference in prevalence of persistence between HbSS patients and HbAA controls was statistically significant (p= 0.02). Conclusion: Persistent hematuria still occurs significantly more among children with SCA, even among those in steady state. Routine urinalysis at follow-up visits in children with SCA is strongly recommended, as this will aid early detection and prompt management to prevent progression to chronic kidney disease.

ABSTRACT

BACKGROUND: The current paradigm for treating toddler's diarrhea comprises dietary modification and fluid restriction. Previous studies show that probiotics and proton-pump inhibitors (PPIs) or H2 blockers could control diarrhea associated with functional gastrointestinal disorders (FGIDs). This study aims to determine and compare the efficacy of a short course of oral ranitidine and a probiotic in the treatment of toddler's diarrhea. METHODS: This study was a parallel-group randomized controlled trial (RCT). We sequentially enrolled 40 patients who met the eligibility criteria. We randomly assigned 20 patients to the oral ranitidine group, ten patients to the probiotic group, and ten patients to the placebo group. In the oral ranitidine group, patients received oral ranitidine (3 mg/kg/day) once daily for 10 days; in the probiotic and placebo groups, they were administered 5 to 10 billion colony-forming units (CFUs) per day of lyophilized Lactobacillus rhamnosus and 50 mg of once-daily oral vitamin C tablet respectively for 10 days. Stool frequency and consistency on the 10th day of the interventions were recorded as the primary outcomes. We used the Student's t-test to determine if there were significant differences in the mean daily stool frequencies in the three intervention groups. A p-value < 0.05 was adopted as the level of statistical significance. RESULTS: In the ranitidine group, stool frequency decreased significantly from an average of five per day on the first day to an average of approximately one per day on the 10th day of intervention (t = 10.462, p <  0.001). Additionally, stool consistency normalized on the 10th day of intervention. In the probiotic group, there was a significant reduction in stool frequency from an average of five per day on the first day to four per day on the 10th day (t = 2.586, p = 0.041), although stool consistency remained loose. However, stool consistency and frequency were not significantly affected in the placebo group (t = 1.964, p = 0.072). CONCLUSION: Oral ranitidine is more effective than probiotics in reducing stool frequency and normalizing stool consistency in toddler's diarrhea. We recommend multi-center trials with appropriate study designs to confirm and validate this finding. TRIAL REGISTRATION: ISRCTN, ISRCTN10783996 .

ABSTRACT

INTRODUCTION: intellectual capacity measured as intelligence quotient (IQ) is one of the determinants of school performance of children. It influences academic achievement, future personal health, social well-being and therefore, is of public health significance. The objective of the study was to determine the intelligence quotient (IQ) and academic performance of primary school children in Enugu-East LGA. METHODS: children who met the inclusion criteria were recruited from both public and private primary schools in the Local Government Area (LGA) using a proportionate multistage sampling technique. Academic performance was classified into high, average and low academic using past records of class assessment. Intelligence quotient was assessed using the Raven´s Standard Progressive Matrices (RSPM) and was grouped into optimal and suboptimal. A semi-structured questionnaire was used to obtain data such as-age, gender, socio-economic indices and family size of the study participants. Analysis was done with Statistical Package for Social Sciences (IBM-SPSS). RESULTS: a total of 1,122 pupils aged 6 to 12 years were recruited. Optimal IQ and high academic performance were found in 54.0% and 58.8% of the study participants. Being from upper social class, in private school, and family size less than 4 were the significant determinants of high IQ and good academic performance (p<0.001). CONCLUSION: low socio-economic status, large family size and public school attendance impact negatively on IQ and academic performance. Hence, measures to curb large family sizes (i.e.>4 children) and improve the socio-economic status of families are needed environmental measures to improve intelligence and academic performance.

ABSTRACT

Posterior reversible encephalopathy syndrome (PRES) is a rare clinical syndrome that has been observed in different age groups, including pediatric patients. Identified triggers of PRES in both children and adults have included immunosuppressive and cytotoxic agents, organ transplantation, severe sepsis, blood transfusion, or evidence of human immunodeficiency virus-1 (HIV-1). Its clinical and radiological courses have been reported as mostly benign and reversible over days to weeks. Computed tomography (CT) scans are helpful in diagnosis, but magnetic resonance imaging (MRI) remains the gold standard. Unfortunately, because of the prohibitive costs of such medical equipment, diagnosis remains a challenge in developing countries. There is a dearth of information about pediatric PRES in resource-poor settings. This narrative aims to draw attention to the possible existence of PRES in children and to identify factors responsible for the difficulty in making the diagnosis. This review will hopefully increase awareness of PRES among pediatricians in order to make early diagnosis and institute appropriate management of this condition.

ABSTRACT

BACKGROUND: The need to generate a robust epidemiological data on the neglected tropical diseases is imperative, in order to encourage access to formal care, drive public policies and ensure the allocation of resources by policy-makers. OBJECTIVES: The objective of this study was to determine the prevalence of soil-transmitted helminthiasis (STH) and its association with nutritional variables among primary school pupils living in urban slums in a South-Eastern sub-Saharan African city of Enugu, Nigeria. METHODS: The stool samples of school-aged children living in urban slums were analyzed for ova of the helminths using the Kato-Katz methods, whereas the nutritional assessment (weight and height) was obtained and analyzed to indicate acute or chronic malnutrition. Degrees of helminthic load were then classified. The socioeconomic status was determined while the prevalence of STH and the relationship between it and the nutritional stratus was assessed to ascertain any significance between being malnourished and having STH as this will inform policy decisions. RESULTS: There were a total of 371 analyzed stool samples from 228 females (61.5%) and 143 males (38.5%), with 285 (76.8%) from the lowest socioeconomic class. The prevalence of STH was 18.1%, while that of acute and chronic malnutrition were 3.3% and 7.5%, respectively. The intensity of infestation was, however, light, with the highest mean egg intensity of 74.4 ± 32.8 documented for ascariasis. There was no statistically significant association between the presence of STH and various indices of acute and chronic malnutrition (P > 0.05). CONCLUSION: STHs prevalence is high among children living in urban slums. Nutritional status was, however, not adversely affected by helminthic infestation.

ABSTRACT

INTRODUCTION: When a child reaches a certain age, he or she moves over to the adult physician. For this to maximally benefit the child, there has to be a process of equipping the child with skills required for taking on more responsibilities. Transitioning involves a process in which the adolescent with chronic illness is prepared ahead of time to enable them to eventually transfer to adult care with good outcomes. In high-income countries with well-organized health financing, the transitioning process begins as early as 12 years. In Africa, this process is not as organized and most hospitals would write a referral letter once the child turns 18 and transfer to adult clinic. In four of our chronic disease clinics (asthma, HIV, sickle cell anaemia and chronic kidney diseases) patients up to 24 years old are still attending the paediatric clinics. Understanding transition readiness among African adolescents remains a gap. Our findings will form a basis for informed practices for adolescent clinics in African countries. METHODS: This was a descriptive cross-sectional study of pre-transition readiness in adolescents and young adults with chronic illnesses attending four outpatient specialist clinics in a tertiary hospital in Enugu Nigeria. This was done using the validated STARx Questionnaire. Total scores were computed and scores nearer the upper limit of 90 were acceptable, while mean subdomain scores of 4 and above were considered as optimal level of transition readiness. Demographic and clinical data were also collected. Acceptability to move on to adult-oriented care was documented using binary response (yes/no). Cross tabulations were done, and likelihood ratios obtained for predictors of acceptability of transition. Significant value was set at p-value of ≤0.05. RESULTS: A total of 142 adolescents and young adults aged 12 to 24 years were studied. There were 38.0% (54), 24.6% (35), 22.5% (32) and 14.8% (21) from HIV, sickle cell anaemia, asthma and nephrology clinics, respectively. Their mean age was 15.6 years ± 2.4, and 48.6% (69) were male. The mean total transition readiness score was 56±14 and this was not nearer the higher spectrum of total scores obtainable. Highest mean scores (3.7) occurred in the knowledge subdomain while least mean score (2) was noted in the use of medication reminders. The males had highest scores in the knowledge subdomain while the females were better informed about medication adherence and were more inquisitive about their chronic illness. Only about 37% (53) of the adolescents and young adults welcomed the idea of moving on to adult-care clinics. Children who had less frequent emergency hospital visits and better treatment outcome accepted the idea of transfer to adult care. Irrespective of the age all participants had suboptimal subdomain scores. High scores did not influence the participants' choice to embrace transfer to adult care. CONCLUSION: There is suboptimal transition readiness irrespective of the age. The older age groups were less willing to transfer to adult care. Better disease knowledge and better communication skills did not positively influence acceptability of transfer to adult care.

ABSTRACT

INTRODUCTION: Persistent hematuria is a chronic complication of sickle cell anemia (SCA) which can progress to chronic kidney disease. The practice of early detection of persistent hematuria in children with SCA in steady state is important for timely intervention. OBJECTIVE: To determine the prevalence of persistent hematuria among children with sickle cell anemia in steady state and compare the result with that of a group of HbAA controls. The outcome will possibly strengthen the health policy on the need for regular screening for persistent hematuria in children with SCA. METHODS: Children with sickle cell anemia, aged 2-18 years in steady state, were recruited consecutively from the sickle cell clinic at the University of Nigeria teaching Hospital Enugu. The controls were similarly recruited from the children's outpatient clinic. To determine persistent hematuria, dipstick urinalysis and microscopy were performed for both subjects and controls at enrollment and repeated after four weeks. RESULTS: Out of the 122 children with SCA studied, 5 (4.1%) had persistent hematuria. None (0%) of the 122 age- and gender-matched HbAA controls had persistent hematuria. This difference in prevalence of persistence between HbSS patients and HbAA controls was statistically significant (p = 0.02). CONCLUSION: Persistent hematuria still occurs significantly more among children with SCA, even among those in steady state. Routine urinalysis at follow-up visits in children with SCA is strongly recommended, as this will aid early detection and prompt management to prevent progression to chronic kidney disease.

ABSTRACT

PURPOSE: Asthma is an important cause of morbidity and mortality worldwide and information on the prevalence of asthma in Nigeria is inconsistent. Nationally representative data, important for health planning is unavailable. We aimed to determine the current prevalence of asthma and allergic rhinitis in Nigeria. MATERIALS AND METHODS: A cross-sectional population survey conducted between June 2017 and March 2018 across five cities representing five geo-political zones in Nigeria. Validated screening questionnaires were used to identify persons with asthma and allergic rhinitis respectively. Asthma was defined as physician diagnosed asthma, clinical asthma and by presence of wheeze in the last 12 months respectively. Socio-demographic information, tobacco smoking, sources of household cooking fuel were also obtained. RESULTS: A total of 20063 participants from 6024 households were screened. The prevalence (95% confidence interval) of physician diagnosed asthma, clinical asthma and wheeze was 2.5% (2.3-2.7%), 6.4% (6.0-6.64%) and 9.0% (8.6-9.4%) respectively. The prevalence of allergic rhinitis was 22.8% (22.2-23.4%). The prevalence of asthma and rhinitis increased with age (prevalence of clinical asthma: 3.1% (2.8-3.4%), 9.8% (9.1-10.5) and 10.7% (9.4%-12.0) among 6-17 years, 18-45 years and >45 years respectively). Prevalence also varied across different cities with the highest prevalence of clinical asthma occurring in Lagos (8.0%) and the lowest in Ilorin (1.1%). The frequency of allergic rhinitis among persons with clinical asthma was 74.7%. Presence of allergic rhinitis, family history of asthma, current smoking and being overweight were independent determinants of current asthma among adults. CONCLUSION: The prevalence of asthma and allergic rhinitis in Nigeria is high with variabilities across regions and age groups. The number of persons with clinical asthma in Nigeria (approximately 13 million) is likely to rank among the highest in Africa. This warrants prioritization by stakeholders and policy makers to actively implement risk reduction measures and increase investment in capacity building for the diagnosis and treatment of asthma and allergic rhinitis.

ABSTRACT

Background: The state of asthma management and asthma control at the population level in Nigeria is unknown. We aimed to determine the level of asthma control and asthma management practices in Nigeria. Methods: A cross-sectional population-based study of 405 participants with current asthma (physician-diagnosed with use of asthma medication or asthma symptoms in the preceding 12 months). We determined the level of asthma control, self-perception of asthma control, health-care use, missed work/school, and medication use. Results: Asthma was controlled in 6.2% of the participants. Night-time awakening and limitation in activity in the preceding 4 weeks were reported by 77.5% and 78.3%, respectively, 56.3% and 14.1% missed work/school and had emergency room visits, respectively, and 11.6% and 38.8% used inhaled corticosteroid and short-acting beta-2 agonist, respectively, in the preceding year. About a third (34.3%) had spirometry ever performed and 46.7% had training on inhaler technique. Nearly 90% with uncontrolled asthma had self-perception of asthma control between somewhat and completely controlled. Conclusion: The level of asthma control in Nigeria is poor with a high burden of asthma symptoms and limitation in activities. This calls for a broad-based approach for the improvement in asthma care that encompasses education and access to medications.
