Pattern and Prevalence of Intestinal Helminthiasis among Human Immunodeficiency Virus-Infected Children at the University of Nigeria Teaching Hospital, Ituku-Ozalla, Enugu State.

BACKGROUND: Children infected with the human immunodeficiency virus (HIV) may be more prone to helminthic infestation because they have depleted immunity, which increases their susceptibility to infection and infestations, even with minimally pathogenic organisms such as helminths. AIM: The prevalence and pattern of intestinal helminthiasis among children living with HIV attending the University of Nigeria Teaching Hospital (UNTH), Ituku-Ozalla, Enugu. PATIENTS AND METHODS: A cross-sectional study in which 70 HIV-infected children were consecutively recruited from the Pediatric HIV clinic and matched for age and sex with 70 children recruited from the children outpatient clinic (CHOP) of UNTH Ituku-Ozalla. Stool samples of study participants were collected and analyzed using the Kato-Katz method and subsequently examined under the microscope for helminths' eggs and larvae. The worm intensity was determined using the theoretical analytic sensitivity (TAS) of 24 eggs per gram (EPG) to obtain the number of eggs per gram of feces. The CD4+ count, which describes the severity of immunosuppression in HIV-positive children was determined using the PARTEC Cyflow counter for the CD4+ lymphocyte count, whereas HIV screening was performed using the rapid diagnostic tests for HIV (Determine, Statpack and Unigold). Data were analyzed using IBM SPSS. RESULTS: The prevalence of intestinal helminthiasis among HIV-infected and non-infected children was 27.1% and 12.9%, respectively (P = 0.038). HIV-positive children were more likely to have intestinal helminthiasis than HIV-negative children (odds ratio [OR] =2.525, 95% confidence interval [CI]: 1.052-6.063). Ascaris lumbricoides was the predominant helminthic species in both HIV-infected and non-infected groups; however, there was no statistical significance between intestinal helminthic species and HIV status (P = 0.655) but the severity of intestinal helminthiasis was significantly associated with decreasing CD4+ count (P = 0.028). The risk factors for intestinal helminthic infestation examined were similar in both HIV-positive and HIV-negative children (P > 0.05). CONCLUSION: There was a significantly higher prevalence of helminthic infestation among HIV-infected children compared to their HIV-negative counterparts. The severity of intestinal helminthiasis was significantly associated with decreasing CD4+ count.

Normalization of Cardiac Structural dimension and Function to Body Surface Area in South East Nigeria Children.

BACKGROUND: Standardizing cardiac valve structures and function to body surface area will help the clinician and surgeons in decision-making. AIM: To evaluate the z-scores of the sizes of cardiac structures and function and to present them in Gaussian curves and reference values. MATERIALS AND METHODS: This was a cross-sectional study that involved 300 apparently healthy children. This study was performed among healthy children from birth to 18 years. Children with a normal echocardiogram, those with no chronic illness, no congenital heart defect, and no acquired heart defect were included in the study. RESULT: The majority fell within the normal limits, as shown in the Gaussian curves. For instance, 40 (13.3%) of atrioventricular (AV) valve diameters were +1 Z-score above the normal, and only 5 (1.7%) were +2 Z-score above the normal. About 9.3% (28/300) had below -2 Z-score below normal, while only 5% had -1 Z-score below normal. Similarly, the left ventricular function z-scores were also derived at -3 Z-scores to +3 Z-scores. The standard reference values were compared with the results obtained from our Z score values. There was no significant difference noted in the Z-scores. P values ranged from 0.07 to 0.84 for all the cardiac structures except for gender, where Z-scores of the mitral valve and left pulmonary artery varied significantly (P = 0.02). CONCLUSION: Reference values of cardiac structure and function were presented using Z scores, and we noted no significant difference when compared with the Western standard values except for the mitral valve and left pulmonary artery.

Echocardiographic Comparison of Left Ventricular Systolic Function and Aortic Blood Flow Velocimetry in Children with Ventricular Septal Defect.

BACKGROUND: The assessments of left ventricular (LV) longitudinal systolic dynamics in children with ventricular septal defect (VSD) have achieved a major milestone in the evaluation of LV systolic function. OBJECTIVES: This study aims to evaluate the LV function, LV mass (LVM), and the descending aorta blood flow in children with VSD compared to that obtained in age and sex-matched controls. RESULTS: The mean LVM of the control, 113.5 ± 123.9 was higher than that of those who had VSD, 75.8 ± 83.9, and the difference in mean was found to be statistically significant (Mann-Whitney U = 2.322, P = 0.022). The mean EF of the control, 67.9 ± 10.3 was comparable to that of those with VSD, 65.6 ± 13.9, (Student's t = 1.223, P = 0.223). Similarly, the mean descending aorta blood flow of control, 1.6 ± 2.2 was comparable to that of those with VSD, 3.9 ± 16.1, (Mann-Whitney U = 1.002, P = 0.321). There was a very weak positive correlation between LVM and descending aorta blood flow among the subjects (n = 85, r = 0.117, P = 0.425). There was a very weak negative correlation between LVM and descending aorta blood flow among control. (n = 85, r = -0.065, P = 0.609). CONCLUSION: The LVM among children with VSD is lower than controls but there is no difference between LV function in subjects and controls. There is a linear increase of LVM with descending aorta blood flow.

Eisenmenger Syndrome: A Revisit of a Hidden but Catastrophic Disease.

BACKGROUND: Eisenmenger syndrome (ES) is a rare condition seen in children with congenital heart disease (CHD). It is characterized by raised pulmonary vascular resistance (PVR) arising from a shunt reversal with the presence of desaturated blood in the systemic circulation. Proper timing and early intervention in children with congenital heart disease have made the syndrome a rare occurrence. However, this cannot be said in developing countries where facilities for the diagnosis and management of children with congenital heart disease are not optimal. OBJECTIVES: The aim of this narrative review is to highlight the importance of early diagnosis and to review the new techniques in the evaluation of children with ES. It also highlights in a snapshot the state of management of ES in a developing country. METHODS: A search for published data on ES was done through several search engines such as Pubmed, google scholar citation, systematic reviews, and meta-analysis. This involves research done over the past 30 years. Keywords such as Eisenmenger'syndrome, 'congenital heart defect', 'Pulmonary hypertension', 'catherterization', 'echocardiography', and children' were used. RESULTS: This review shows the new technique in the diagnosis, aetio-pathogenesis, management and treatment of children with ES in-depth descriptive analysis and new advances in the management of children with ES. CONCLUSION: Eisenmenger syndrome is a preventable disease that can be curbed by early diagnosis and treatment of children with congenital heart disease, especially in the developing world.

CONTEXTE: Le syndrome d'Eisenmenger (SE) est une affection rare observée chez les enfants atteints de cardiopathie congénitale. Il se caractérise par une augmentation de la résistance vasculaire pulmonaire (RVP) due à l'inversion d'un shunt et à la présence de sang désaturé dans la circulation systémique. Le syndrome est devenu rare chez les enfants atteints de cardiopathie congénitale grâce à un choix judicieux du moment et à une intervention précoce. Toutefois, il n'en va pas de même dans les pays en développement où les moyens de diagnostic et de prise en charge des enfants atteints de cardiopathies congénitales ne sont pas optimaux. OBJECTIFS: L'objectif de cette revue narrative est de souligner l'importance d'un diagnostic précoce et de passer en revue les nouvelles techniques d'évaluation des enfants atteints de SE. Elle met également en lumière, sous forme d'un instantané, l'état de la prise en charge de l'ES dans un pays en développement. MÉTHODES: Une recherche de données publiées sur l'ES a été effectuée à l'aide de plusieurs moteurs de recherche tels que Pubmed, google scholar citation, revues systématiques et méta-analyses. Il s'agit de recherches effectuées au cours des 30 dernières années. Des mots clés tels que "syndrome d'Eisenmenger", "malformation cardiaque congénitale", "hypertension pulmonaire", "cathétérisme", "échocardiographie" et "enfants" ont été utilisés. RÉSULTATS: Cette revue présente les nouvelles techniques de diagnostic, d'étio-pathogénie, de prise en charge et de traitement des enfants atteints de SE, ainsi qu'une analyse descriptive approfondie et les nouvelles avancées dans la prise en charge des enfants atteints de SE. CONCLUSION: Le syndrome d'Eisenmenger est une maladie évitable qui peut être enrayée par un diagnostic et un traitement précoces des enfants atteints de cardiopathies congénitales, en particulier dans les pays en développement.
