Rheumatic heart disease patients were young, predominantly female, and had high prevalence of major cardiovascular complications. There is suboptimal utilization of secondary antibiotic prophylaxis, oral anti-coagulation, and contraception, and variations in the use of percutaneous and surgical interventions by country income level.

Background:The patterns of childhood acquired heart diseases (AHD) vary in different parts of the world and may evolve over time. We aimed to compare the pattern of childhood AHD in our institution to the historical and contemporary patterns in other parts of the country, and to highlight possible regional differences and changes in trend.Materials and Methods:Pediatric echocardiography records spanning a period of 10 years were reviewed. Echocardiography records of children with echocardiographic or irrefutable clinical diagnoses of AHD were identified and relevant data extracted from their records.Results:One hundred and seventy five children were diagnosed with AHD during the period, including seven that had coexisting congenital heart disease (CHD). They were aged 4 weeks to 18 years (mean 9.84΁4.5 years) and comprised 80 (45.7%) males and 95 (54.3%) females. Rheumatic heart disease (RHD) was the cause of the AHD in 101 (58.0%) children, followed by dilated cardiomyopathy (33 cases, 18.9%) which was the most frequent AHD in younger (under 5 years) children. Other AHD encountered were cor pulmonale in 16 (9.1%), pericardial disease in 15 (8.6%), infective endocarditis in 8 (4.6%) and aortic aneurysms in 2 (1.1%) children. Only one case each of endomyocardial fibrosis (EMF) and Kawasaki Disease were seen during the period.Conclusions:The majority of childhood acquired heart diseases in our environment are still of infectious aeitology, with RHD remaining the most frequent, particularly in older children. Community-based screening and multicenter collaborative studies will help to better describe the pattern of AHD in our country. More vigorous pursuit of the Millennium development goals will contribute to reducing the burden of childhood acquired heart diseases in the country.

BackgroundEvents in pregnancy play an important role in predisposing the newborn to the risk of developing CHD. This study evaluated the association between maternal preeclampsia and her offspring risk of CHD. MethodsThis is a cohort study of 90 sex-matched neonates (45 each born to women with preeclampsia and normal pregnancy) in Jos, Nigeria. Anthropometry was taken shortly after delivery using standard protocols. Echocardiography was performed within 24 hours of life and repeated 7 and 28 days later. SPSS version 25 was used in all analyses. Statistical significance was set at p<0.05. ResultsCongenital heart disease (CHD) was observed in 27 (30.0%) of newborns of women with preeclampsia compared with 11 (12.1%) of newborns without preeclampsia (p<0.001) at the end of 7 days and in 19 (21.1%) of newborns of women with preeclampsia and 3 (3.3%) of newborns of women without preeclampsia by the end of the 4 th week of life (p<0.001). Overall, ASD (4 newborns), PDA (21 newborns), patent foramen ovale (14 newborns) and VSD (2 newborns) were the prevalent lesions found among all the newborns studied in the first week of life. Isolated atrial and ventricular septal defects were seen in 4 (4.4%) of the newborns of women with preeclampsia. Being the infant of a woman with preeclampsia was associated with about 8-fold increased risk of having CHD (OR = 7.9, 95% CI = 2.5-24.9, p<0.001).

Aims: To determine the incidence and severity of zidovudine-induced anaemia in HIVinfected children initiated on anti-retroviral therapy in Jos, Nigeria. Study Design: This was an observational cohort study.

Left ventricular systolic dysfunction is significantly more frequent in HIV-infected children compared with controls. Left ventricular systolic function in HIV-infected children deteriorates with increasing age and should be serially evaluated in them.
