Things must not fall apart: the ripple effects of the COVID-19 pandemic on children in sub-Saharan Africa.

Zero to 19 year-old children in sub-Saharan Africa bear a disproportionate proportion of the global burden of communicable and non-communicable diseases. Significant public health gains have been made in the fight against these diseases, however, factors such as underequipped health systems, disease outbreaks, conflict, and political instability continue to challenge prevention and control. The novel coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) introduces new challenges to public health programs in sub-Saharan Africa. Of particular concern are programs targeting major conditions among children, such as undernutrition, vaccine-preventable pneumonia and diarrhea, malaria, tuberculosis, HIV, and sickle cell disease. This article focuses on the impact of the COVID-19 pandemic on child health in sub-Saharan Africa. We review the epidemiology of major pediatric diseases and, referencing modeling projections, discuss the short- and long-term impact of the pandemic on major disease control. We deliberate on potential complications of SARS-CoV-2 co-infections/co-morbidities and identify critical social and ethical issues. Furthermore, we highlight the paucity of COVID-19 data and clinical trials in this region and the lack of child participants in ongoing studies. Lastly, approaches and interventions to mitigate the pandemic's impact on child health outcomes are discussed. IMPACT: Children in sub-Saharan Africa bear a disproportionate burden of communicable and non-communicable diseases globally; this remains true even as the COVID-19 pandemic persists. Amidst the fast-expanding COVID-19 literature, there is little comprehensive coverage of the pandemic's indirect impact on child health in sub-Saharan Africa. This article comprehensively outlines the threat that the pandemic poses to major disease prevention and control for children in sub-Saharan Africa. It discusses the potential impact of SARS-CoV-2 co-infections/co-morbidities, highlights research gaps, and advocates for data and action to mitigate the ripple effects of the pandemic on this population.

Time to sputum culture conversion and treatment outcome among the first cohort of multidrug resistant tuberculosis patients in a high burden country.

BACKGROUND: Sputum conversion considered the most important interim indicator of the efficacy of anti-tuberculosis treatment was assessed at varying time points among the first cohort of multidrug resistant tuberculosis (MDR-TB) patients in a National TB Control Programme. METHODS: A retrospective study was conducted for the period between 2010 and 2013, at the premiere MDR-TB treatment center in Nigeria. Genexpert, culture and drug susceptibility tests were carried out. Total duration of treatment was 20 months. RESULTS: A total of 115 patients were studied consisting of 76 (66.1%) males and 39 (33.9%) females with ages ranging between 15 and 65 years. Median time to sputum conversion was 2.06 months (95% confident interval [CI] = 1.82, 2.30). At the end of the first month, 43 (37.4%) patients sputum converted, increasing to 104 (90.4%) at the end of three months. There was no significant interaction with Human Immunodeficiency Virus (HIV) status. Overall treatment success was 69.4%. The default rate was 8.7% (10/115) and 25 (21.7%) deaths were recorded. CONCLUSION: The treatment success rate in the study was high with most of cases with or without HIV infection, achieving sputum culture conversion within 2 months of commencing treatment. Expansion of MDR-TB treatment services is necessary to reduce the death rate.

Blood Transfusion-Associated HIV Infection in Children in Ibadan, Nigeria.

INTRODUCTION: This study describes the epidemiologic features and clinical course of children with blood transfusion-associated HIV infection (TAHI) in Ibadan, Nigeria. METHODOLOGY: All children diagnosed to have TAHI at the University College Hospital, Ibadan, were studied and compared with children who acquired HIV vertically using the pediatric HIV database in the hospital. RESULTS: Transfusion-associated HIV infection accounted for 14 (2.3%) of the 597 children diagnosed to have HIV infection between January 2004 and December 2011. The mean age at diagnosis of TAHI was 10.2 years and that of vertically acquired HIV infection was 3.9 years ( P < .001). In 9 cases, blood transfusion took place in private hospitals and in 5 cases in public hospitals. Median interval between infection and diagnosis of AIDS was 84 months in cases with TAHI and 48 months in vertically acquired cases ( P = .542). CONCLUSION: Optimal blood safety practices are advocated for prevention of TAHI in Nigeria.

Mucocutaneous Disorders of Pediatric HIV in South West Nigeria: Surrogates for Immunologic and Virologic Indices.

OBJECTIVES: Nigeria has the world's highest burden of pediatric HIV. In the face of paucity of monitoring tests in Nigeria, we studied the spectrum of pediatric mucocutaneous manifestations and evaluated their clinical utility as surrogate markers for immunodeficiency and plasma viral load levels. METHODS: Cross-sectional study comparing mucocutaneous manifestations in 155 HIV-positive children aged 12 weeks to 14 years with 155 HIV-negative children. Relationships between mucocutaneous manifestations in HIV-infected patients and their immunologic and virologic indices were analyzed. RESULTS: Mucocutaneous lesions were seen in 53.5% of HIV-infected children compared with 18.1% of the controls. Prevalence of lesions increased with worsening levels of immunodeficiency and increasing viral loads (P < .01). Oral candidiasis, angular stomatitis, and fluffy hair were associated with more severe degrees of immunodeficiency. CONCLUSION: Mucocutaneous disorders are common in HIV-infected children. Oral candidiasis and nutritional dermatoses can be used as surrogates for advanced or severe immunodeficiency.

Oral lesions and their association with CD4 count and viral load in HIV positive Nigerian children.

BACKGROUND: ral lesions may indicate the presence of HIV infection and may differ in children and adults in different regions. AIM: To determine the prevalence, types of oral lesions in HIV positive children and their association with the clinical stage, CD4 count and viral load. METHODS: A cross-sectional study involving consecutive HIV positive children whose sero-positive status was confirmed with ELISA screening and Western immunoblot. Oral lesions were diagnosed clinically by a trained dental surgeon using previously established classification. Data obtained was analyzed with SPSS 15.0. RESULTS: There were 127 children with age range of 3 to 204 months (median: 60 months) and male preponderance of 58.3% (n=74). 55.9% (n=71) of the subjects had oral lesions and pseudomembranous candidiasis (55.9%) was the commonest followed by caries (12.7%), xerostomia (7.8%) and gingivitis (6.9%). Correlation between prevalence of oral lesions and clinical stage of the disease did not reveal any statistically significant association (p=0.354). Also there is no statistically significant difference in prevalence of oral lesions between children on Antiretroviral Therapy (ART) and those who are not on ART (p=0.875). Incidence of oral lesions was however associated with lower mean baseline CD4 count (p= 0.004) but not with mean log10 viral load (p=0.256). CONCLUSION: This study has shown that HIV associated oral lesions are prevalent in our environment and antiretroviral therapy does not have significant correlation with occurrence of these lesions in HIV infected children. CD4 count is a better indicator of disease progression than viral load.

Parotid gland enlargement in pediatric HIV population.

OBJECTIVES: To establish the significance of parotid enlargement, state frequency, cytological features and effect of antiretroviral therapy (ART) on parotid enlargement among a pediatric HIV population. STUDY DESIGN: A 6 month cross sectional survey that utilised clinical features, serial immunological indices and fine needle aspiration cytology. RESULTS: 287 HIV positive children were seen at special paediatric clinic of the University College Hospital, Ibadan, Nigeria, 114 (39.7%) had oral features and among these 24 (8.4%) had parotid involvement comprising of 10 males and 14 females. The overall mean age was 43.4 + 39.7 months compared with 59.6 + 36.5 months in the parotid enlargement group (p = 0.03). Mean ages of parotid enlargement and non enlargement group was significantly different (p = 0.03). The mode of transmission was vertical in (91.7%), 87.5% was bilateral (87.5%) and (75%) presented as a syndrome state with generalised lymphadenopathy. The predominant cytology was lymphoid hyperplasia (62.5%). ART resulted in marked clinical reduction in all the cases and statistically significant improvement in serum indices of CD4 count, CD4% and viral load (p = 0.001, 0.000 & 0.009 respectively). CONCLUSION: HIV positive children often present with bilateral parotid enlargement and the syndrome state with classical clinical and cytological features of lymphoid hyperplasia predominated. ART resulted in satisfactory reduction of the swellings in most of the cases with no need for further intervention.

Prevalence and clinical pattern of paediatric HIV infection at the University College Hospital, Ibadan, Nigeria: a prospective cross-sectional study.

BACKGROUND: The prevalence of Paediatric HIV infection is largely unknown in many countries in sub-Saharan Africa. This study was aimed at determining the prevalence, clinical pattern of HIV infection and outcome among new patients aged <15 years using age-specific diagnostic methods. METHODS: A prospective cross sectional study was carried out using the provider initiated HIV testing and counselling (PITC) model. HIV rapid test in parallel was used for screening and confirmation was with HIV DNA PCR in children <18 months and Western Blot in children ≥ 18 months. RESULTS: A total of 600 children were enrolled with ages ranging between one day and 179 months. Male: female ratio was 1.2:1. HIV seroprevalence was 12.3% and after confirmatory tests, the prevalence was 10%. Fourteen (37.8%) of the children aged less 18 months were exposed but not infected. Mother-to-child transmission accounted for 93.3% of cases. Features predictive of HIV infection were diarrhoea, cough, weight loss, ear discharge generalized lymphadenopathy, presence of skin lesions, parotid swelling and oral thrush. About 75% presented in advanced or severe clinical stages of the disease, 56.8% had severe immunodeficiency while 50% had viral loads more than 100,000 copies/ml. Mortality rate was 14.3% among HIV positive compared with 11.3% in HIV negative children but was not significant. Among the HIV positive children, 26.7% were orphans. CONCLUSIONS: The prevalence rate of HIV infection among new patients screened using the PITC model was high, majority resulting from mother-to-child transmission. Most children presented in advanced stages of the disease and mortality rate among them was high. Though, the study site being a referral centre might have contributed to the high prevalence observed in this study, there is a need to expand access to PMTCT services, ensure implementation of PITC in paediatric settings and expand support services for HIV infected children.

Disclosure of HIV status to infected children in a Nigerian HIV Care Programme.

With increasing survival of HIV-infected children, parents face the challenges of disclosure to the children. The aim of this study was to assess the rate of HIV disclosure to children in Ibadan and the factors influencing it in order to guide design of strategies for successful disclosure. A semi-structured questionnaire was administered to consecutive consenting caregivers of HIV-infected children aged ≥6 years attending the Paediatric Infectious Disease Clinic of the University College Hospital, Ibadan, between November 2008 and October 2009. Caregivers of 96 children (46 boys, 50 girls) infected with HIV were interviewed. The ages of the children ranged from 6 to 14 years with a mean (SD) of 8.8 (2.2) years. Disclosure had been done in only 13 (13.5%) of the children; ages at disclosure ranged from 4.5 to 13 years with a mean of 8.7 (SD = 2.2). Disclosure was associated with age above 10 years. Reasons given by carers for non-disclosure in 83 caregivers included inability of the children to understand in 53 (63.9%), fear of disclosure to other children 34 (41.0%), fear of disclosure to family/friends in 28 (33.7%), fear of psychological disturbance of the children in 26 (31.3%) and fear of blaming the parents in 22 (26.5%). Twenty (20.8%) of the children have asked questions relating to their diagnosis and the responses are often evasive. Caregivers felt disclosure had helped adherence to antiretroviral therapy in 7 (63.6%) of the 11 children on antiretroviral drugs in whom there was disclosure but no effect on the remaining. There is a need to assist parents and health care providers in successfully disclosing HIV status to infected children without adverse consequences.

Clinical and Immunological Profile of Pediatric HIV Infection in Ibadan, Nigeria.

In spite of the increasing number of children living with HIV in Nigeria, published data on their clinical profile are few. We describe the clinical profile at presentation of HIV-infected children at the University College Hospital, Ibadan, in a prospective study. Among 272 children studied (149 [54.8%] males; mean age 4.2 years [range 2 months to 15 years]), infection was acquired through vertical transmission in 252 (92.6%), blood transfusion in 5 (1.80%), and undetermined routes in 15 (5.5%) cases. Clinical features included weight loss (62.5%), prolonged fever (55.4%), generalized lymphadenopathy (48.6%), chronic cough (45.4%), and persistent diarrhea (28.3%). Tuberculosis was present in 45.3%, World Health Organization (WHO) clinical stages 3 and 4 disease in 70.6% and severe immunosuppression in 44.5% of cases. Pediatric HIV in Ibadan is acquired mainly vertically and most cases present with severe disease. Improved access to prevention services and early diagnosis are recommended.

Proximate predictors of early antenatal registration among Nigerian pregnant women.

BACKGROUND: Provision of antenatal care (ANC) is included in the pillars of maternal health care promoted as effective answers to maternal mortality. Early antenatal registration has been linked with optimal utilization and appreciable reduction of perinatal morbidity and mortality. This study aimed to determine the profile and possible predictors of pregnant women who presented early for antenatal registration. METHODS: A cross-sectional study was conducted among 796 women presented for antenatal registration at a tertiary hospital. Information was obtained by a self-administered open- and closed-ended questionnaire and analyzed with Statistical Package of Social Science (SPSS) 12.0 software. RESULTS: The mean gestational age at booking was 20 weeks. Univariate analysis showed that first trimester booking was significantly with more educated women, professionals, women of lower parity and those who have had previous stillbirths (P < 0.05). Low parity (OR 1.76, 95% CI 2.79-1.11) and previous stillbirth (OR 2.97, 95% CI 1.61-5.51) were significant predictors of early booking on multivariate analysis. CONCLUSION: Long-term advocacy and investment in female education will contribute significantly to primary prevention of late or non-attendance of ANC. Pre-conception clinics and community awareness campaigns would be necessary tools to reach these women and encourage them to register early when pregnant.

HIV/AIDS in 3 generations: case series.

BACKGROUND: The HIV pandemic is one of the greatest challenges facing humanity, and generations may be wiped out if effective prevention, treatment, and care are not in place. CASE REPORTS: A total of 3 families are presented. In the first 2, the children represented the third generation in their families to be infected with HIV and probably had mother-to-child transmission of the disease. The children in the third family were HIV negative. The mothers and grandmothers in all the families were infected with HIV. Risky sexual behavior involving multiple sexual partnering was recorded among them, some of whom had died from AIDS-related illness. This has serious implications in the care of the infected and affected children as they had been made vulnerable by their circumstances. CONCLUSION: HIV/AIDS has been around long enough now to cross generations as shown in the reported cases, which resulted in serious health and socioeconomic effects in the affected families.

Infant-feeding pattern of HIV-positive women in a prevention of mother-to-child transmission (PMTCT) programme.

OBJECTIVES: To evaluate the infant-feeding choices, practices and possible determinants among HIV-positive women enrolled in a prevention of mother-to-child transmission programme in Ibadan, Nigeria. METHODS: A cross-sectional survey involving HIV-positive women who had received infant-feeding counselling prior to delivery. A structured questionnaire was administered at < or = 72 hrs and not > or = 6 weeks of delivery and was complemented with an in-depth interview. RESULTS: A total of 241 women were studied. The choice of infant feeding was formula for 223 (93.5%) and in actual practice, 9 (3.7%) mothers admitted mixed feeding. There was no statistical significant difference between the feeding pattern and the socio-demographic characteristics. The major factor influencing the choice of infant feeding was "The desire to reduce the risk of transmission" which was recorded among 204 (84.6%) of the women. Greatest support in maintaining infant-feeding option was the spouse (36.1%). From the in-depth interview of 23 non-breastfeeding (infant formula) mothers, the major challenge faced was stigmatisation. CONCLUSION: Despite the premium placed on breastfeeding in this locality, with infant-feeding counselling, most HIV-positive women chose and practiced formula feeding. It is necessary to address how best HIV-positive mothers could handle or overcome criticisms and stigmatisation by others.
