    Prevalence and determinants of depression among patients with hypertension: A cross‑sectional comparison study in Ghana and Nigeria
    (Wolters Kluwer ‑ Medknow, 2020) Ademola, A. D.; Boima, V.; Odusola, A. O.; Agyekum, F.; Nwafor, C. E.; Salako, B. L.
    Background: Despite evidence linking depression to poor blood pressure (BP) control and increased hypertension‑related morbidity and mortality, there is paucity of data about depression among patients with hypertension in sub‑Saharan Africa. We assessed factors associated with depression among patients with hypertension in Ghana and Nigeria. Subjects and Methods: Patients with hypertension were recruited from four hospitals: In Ghana, Korle Bu Teaching Hospital (n = 120), and in Nigeria, the University of Port Harcourt Teaching Hospital, the Lagos State General Hospital, and the University College Hospital Ibadan (n = 237). Demographic, socioeconomic, psychosocial, and clinical factors which predicted depression among the study cohort were assessed by logistic regression. Depression and beliefs about medications were assessed with the Patient Health Questionnaire (PHQ‑9) and the Beliefs about Medication Questionnaire, respectively. Depression was regarded as PHQ‑9 score >4. Results: The mean ages of the Ghanaian and Nigerian cohort were 57.0 ± 13.7 years (58.3% female) and 56.4 ± 12.9 years (57.0% female), respectively. Prevalence of depression was 41.7% and 26.6% among the Ghanaian and Nigerian cohorts, respectively. Significant predictors of depression in the Nigerian cohort were age in years [OR 0.97 (0.95–0.99)], concern about medications [OR 1.15 (1.03–1.30)], and poor BP control [OR 2.06 (1.09–3.88)]. Young age was the only independent predictor of depression in the Nigerian cohort. In the Ghanaian cohort, none of the factors significantly predicted depression. Conclusion: Prevalence of depression is high among patients with hypertension in Ghana and Nigeria. Screening and treatment of depression among patients with hypertension in Ghana and Nigeria may have important implications for improving outcomes.

    Childhood nephrotic syndrome in tropical Africa: then and now
    (Taylor and Francis, 2017) Olowu, W. A.; Ademola, A. D.; Ajite, A. B.; Saad, Y. M.
    This descriptive and comparative review examines the changing epidemiology, treatment, renal and patient outcome of childhood nephrotic syndrome (NS) in tropical Africa (TpAfr). In the 1960s to 1980s, corticosteroid-resistant non-minimal change disease (nMCD) including quartan malaria nephropathy (QMN) was the dominant renal histopathology type. The overall incidence of NS was 0.35–1.34% of hospital admissions. Median age at onset of NS ranged between 4.0 and 12.0 years while the mean (SD) age range was 5.8 (3.8) to 10.3 (4.8) years across studies. The male: female ratio was 1.6:1.0. The overall mean (SD) incidence of idiopathic minimal change disease (MCD) [21.6 (18.6%)] compared with idiopathic nMCD [59.1 (25.7%)] demonstrates significant dominance of the latter (p = 0.0001). Post-1989, the following mean (SD) incidences of histopathological types were: MCD 20.4 (17.7%), focal segmental glomerulosclerosis 39.0 (26.3%), membranoproliferative glomerulonephritis 25.4 (16.8%), proliferative glomerulonephritis 16.7 (27.0%) and membranous nephropathy 7.4 (4.5%). While the mean (SD) proportion of steroid resistance (SR) [73.5 (19.2%)] was significantly greater than the mean complete remission (CR) [26.5 (19.2%)] during 1960-1989 (p=0.005), mean (SD) SR [27.4 (25.3%)] was significantly lower than mean (SD) CR [66.1 (28.0%)] post-1989 (p < 0.001). Unlike QMN, hepatitis B virus, HIV infection, sickle cell disease and systemic lupus erythematosus are now increasingly being associated with NS in TpAfr. Mean (SD) renal survival post-1989 was 58.3 (37.0%) while all-cause mortality was 9.8%. Children with NS now survive better than before, reflecting improved access to healthcare and transition to a clinical pattern favouring idiopathic NS and increased sensitivity to corticosteroids.

    Kidney disease in hepatitis B surface antigen-positive children: experience from a centre in south-west Nigeria and a review of the Nigerian literature
    (Taylor and Francis, 2017) Asinobi, A. O.; Ademola, A. D.; Okolo, C. A.; Adepoju, A. A.; Samuel, S. M.; Hoy, W. E.
    Background: Kidney disease is an important extra-hepatic manifestation of hepatitis B virus (HBV) infection. However, there is paucity of recent literature on kidney disease in children and adolescents with HBV infection from several parts of sub-Saharan Africa including Nigeria. Objective: To review the pattern of kidney disease in hepatitis B surface antigen (HBsAg)-positive children and adolescents seen at a tertiary hospital in south-west Nigeria. Methods: A retrospective study was undertaken of HBsAg-seropositive children with kidney disease managed at University College Hospital, Ibadan, from January 2004 to December 2015. Patients were identified from the paediatric nephrology unit admissions and the renal histology registers. Results: 24 children and adolescents were studied, 17 of whom were male (70.8%), and the median age was 10.0 years (range 3–15). Ten (41.7%) had nephrotic syndrome, five (20.8%) had non-nephrotic glomerulonephritis, five (20.8%) were in end-stage renal disease (ESRD), including a patient with posterior urethral valves, and four had acute kidney injury secondary to acute tubular necrosis. Renal histology was available for 10 patients: nine had nephrotic syndrome associated with minimal change disease in six, focal segmental glomerulosclerosis in two and one had membanoproliferative glomerulonephritis. The patient with non-nephrotic glomerulonephritis had diffuse global sclerosis. Conclusion: The pattern of kidney disease in HBV-positive children demonstrated a predominance of nephrotic syndrome, followed by non-nephrotic glomerulonephritis, ESRD and acute kidney injury. Better diagnostic facilities and treatment are required. Prevention of HBV infection by universal childhood immunisation is the ultimate goal.

    Congenital anomalies in Ibadan, Nigeria
    (Spectrum Books. Publisher, Ibadan Nigeria, 2016) Ayede, A. I.; Adeleye, A. O.; Olusanya, A. A.; Ademola, A. D.; Olayemi, O.; Ogbole, G. I.; Akinmoladun, J. A.; Agunloye, A. M.; Akinrinoye, O. O.; Takure, A. O.; Oyewole, O. B.; Oluwatosin, O. M.; Omokhodion, S. I.
    Background: There is a need for a multidisciplinary database that can be used as a potential source for developing a protocol and a guideline for a possible nationwide prospective surveillance of congenital anomalies in Nigeria. Methods: This five-year cross-sectional retrospective survey of data from January 2009 to December 2013 was done at the University College Hospital, Ibadan. Data were collected from the admission records on the wards in 8 specialty units with the most workable documented clinical records of congenital anomalies in their care using a predesigned proforma. Proportions of congenital anomalies were determined based on systemic classification of the anomalies and the descriptive terms used were according to the ICD_10-chapter XVIII_RCPCH extension. Result: The total number of patients with congenital anomalies whose records were obtained from the ward registers was 1311, there were 75 (5.7%) missing case notes while information was obtained on 1236 (94.3%) patients. There were a total of 1479 anomalies with multiple anomalies seen in 16.1% of the patients. The male/female ratio was 2:1 and multiple births as well as positive family history of birth defects were seen in about 2.4% and 2.2% of cases respectively. Prenatal diagnosis of the anomalies was documented in only 11 cases (0.9%). Only about one in five cases presented within the neonatal period, and defects of the abdominal wall as well as the cranial-facial-orbital regions were the most prevalent. Next were those in the cardiovascular, spinal column, anorectal and genital, as well as musculoskeletal systems. Conclusion: The size and pan-systemic profiles of the birth defects documented in this study calls for further action on this all-important cause of childhood mortality and significant life-long morbidity in our country.

    Haemodialysis for paediatric acute kidney injury in a low resource setting: experience from a tertiary hospital in South West Nigeria
    (Oxford University Press, 2016) Asinobi, A. O.; Ademola, A. D.; Alao, M. A.
    Background: Acute kidney injury (AKI) is an important cause of preventable mortality among children. Management of AKI may require renal replacement therapy (RRT) but access to RRT for children in low resource settings is limited. Our study explored the role of haemodialysis in the management of children with AKI in a low resource setting in terms of aetiology and outcomes. Methods: A review of patients managed in the Paediatric Nephrology Unit, University College Hospital Ibadan, South-West Nigeria, who underwent haemodialysis for AKI from January 2006 to December 2014. Results: Sixty-eight patients (55.9% males), aged 3–16 (mean ± standard deviation, 9.0 ± 3.4) years were studied. The causes of AKI were sepsis (22.1%), malaria (17.6%) and glomerulonephritis (17.6%), intravascular haemolysis—cause unknown (16.2%), G6PDH deficiency (7.4%), malignancy (8.8%) and haemoglobinopathy (5.9%). The number of sessions of haemodialysis ranged from 1 to 10 (mode = 2 sessions) over a period of 1–55 days. Mortality was 27.9% (n = 19) and was related to the aetiology of AKI (P = 0.000): no deaths among patients with intravascular haemolysis or malaria, six deaths among patients with sepsis (40%), six (50%) among the patients with glomerulonephritis, while all the patients with malignancies died. Conclusions: The outcome of haemodialysis for AKI in Nigeria is relatively good and is related to the underlying aetiology of AKI. In addition to peritoneal dialysis, intermittent haemodialysis may have a role in the management of paediatric AKI in low resource settings and should be supported.

    Trends in the epidemiology of severe pediatric non-surgical renal disorders in Ibadan Nigeria: A marked increase in the incidence of acute kidney injury
    (Sciencedomain International, 2016) Asinobi, A. O.; Ademola, A. D.; Ogunkunle, O. O.; Yaria, J.
    Background: Renal disorders are increasingly being recognized as major contributors to morbidity and mortality. Variability in their pattern in different populations and regions of the world and changes occurring with time have been demonstrated. We aimed to determine the current trends in the pattern of severe non-surgical childhood renal disorders at our Centre and compare the findings with previous studies. Methodology: A descriptive analytical study was carried out on consecutive incident cases of nonsurgical renal disorders aged 14 years and below, managed in the Pediatric Nephrology Unit of the University College Hospital, Ibadan, Nigeria. Two separate time periods were studied. Results: A total of 869 incident cases of severe non-surgical disorders were admitted during the study periods. There was an increase in the hospital incidence from 1.5 to 2.2 per 100 pediatric admissions and in the average yearly admission from 43 to 103. The crude annual incidence increased from 42 per million age-related population (PMARP) to 86 (PMARP) at the end of the two study periods. The most remarkable increase occurred with Acute Kidney Injury, which showed a 6.5-fold rise and was the most common cause of renal morbidity and mortality in children encountered in the study. Interventional measures resulted in early detection, prompt treatment and reduced mortality. Conclusion: The study has shown an increase in the incidence of severe childhood renal disorders in Ibadan, with Acute Kidney Injury being the leading non-surgical renal disorder. A significant decline in case fatality rates was demonstrated in recent years.

    An Audit of the Use of Renal Function Tests among Paediatric Mortalities
    (Sciencedomain International, 2016) Asinobi, A. O.; Ademola, A. D.; Ogunku, O. O.
    Background: Acute kidney injury is a frequent and serious complication encountered in critically ill children and is an independent risk factor for mortality. Major causes of childhood mortality in our environment are conditions frequently complicated by kidney failure, yet kidney failure is conspicuously absent in many of the reports. The actual proportion of these critically ill children subjected to renal function tests is not known. In view of the low representation of kidney failure as a cause of mortality in our environment, we sought to know what proportion of critically ill/dying patients had renal functions tests done and to identify any cases of missed diagnosis. Methods: This was a descriptive study of the mortalities in the Department of Paediatrics, University College Hospital, Ibadan, between August 2004 and May 2006, particularly those due to kidney failure. Data from the departmental mortality database collected on a weekly basis were analyzed. Results: Out of 4,941 admissions, there were 542 mortalities (age 1day -13 years) giving a mortality rate of 11%. Low birth weight, malaria, severe perinatal asphyxia, meningitis and neonatal tetanus were the leading five causes of death. Over 80% of the mortalities were under-fives
