Audit of Stroke Admissions in a Tertiary Hospital in South East Nigeria.

INTRODUCTION: Stroke is one of the commonest causes of medical admissions and mortality in Nigeria. Documenting the pattern of stroke and risk factors for stroke is important not only for public health policy makers but also for physicians in implementing both primary and secondary preventive programs. OBJECTIVES: The aim of this study was therefore to document the pattern of stroke and risk factors for stroke in stroke patients admitted in a tertiary hospital in Enugu. METHODS: This was a cross-sectional descriptive study carried out at Enugu State University Teaching Hospital, Enugu. Data were analyzed using the SPSS version 26 (IBM Corporation, New York, USA). RESULTS: Data from 350 patients were included in the present study. The three commonest risk factors for stroke were diabetes (69.1%), hypertension (64.9%), and age 65 years and above (51.1%). A total of 74.9% of the patients had ischemic stroke and 25.1% had hemorrhagic stroke. Hemorrhagic stroke was significantly higher in patients < 50 years (46.5%) and people with hypertension, (31.7%). About 31.4% of the patients had two risk factors and 28.6% had three risk factors. Age 65 years and above positively correlated with having ischemic stroke and hypertension positively correlated with hemorrhagic stroke. When controlled for age, the correlation between hypertension and hemorrhagic stroke was still significant. CONCLUSION: The reported frequency of ischemic stroke was 74.9% and of hemorrhagic stroke was 25.1%. The commonest risk factors for stroke documented among stroke patients in a tertiary hospital in Enugu were diabetes, hypertension, and age 65 years and above. When controlled for age, the correlation between hypertension and hemorrhagic stroke was still significant.

INTRODUCTION: L'accident vasculaire cérébral (AVC) est l'une des causes les plus courantes d'admissions médicales et de mortalité au Nigeria. Il est important de documenter le profil des et les facteurs de risque des accidents vasculaires cérébraux sont importants non seulement pour le santé publique mais aussi pour les médecins dans la mise en œuvre des programmes de prévention primaire et secondaire. OBJECTIFS: L'objectif de cette étude était donc de documenter le modèle d'AVC et les facteurs de risque d'AVC chez les patients admis dans un hôpital tertiaire d'Enugu. MÉTHODES: Il s'agit d'une étude descriptive transversale menée à l'hôpital universitaire d'Enugu, Enugu. Les données ont été analysées à l'aide du SPSS version 26 (IBM Corporation, New York, USA). RÉSULTATS: Les données de 350 patients ont été incluses dans la présente étude. Les trois facteurs de risque d'accident vasculaire cérébral les plus courants étaient le diabète (69,1 %), l'hypertension (64,9 %) et l'âge de 65 ans et plus (51,1 %). Un total de 74,9 % des patients ont eu un AVC ischémique et 25,1 % un AVC hémorragique. L'AVC hémorragique était significativement plus élevé chez les patients < 50ans (46,5 %) et les personnes souffrant d'hypertension (31,7 %). Environ 31,4 % des patients présentaient deux facteurs de risque et 28,6 % trois facteurs de risque. Âge 65 ans et plus était positivement corrélé au fait d'avoir un AVC ischémique et l'hypertension était en corrélation positive avec l'AVC hémorragique. Après contrôle de l'âge, la corrélation entrel'hypertension et l'AVC hémorragique était toujours significative. CONCLUSION: La fréquence rapportée de l'accident vasculaire cérébral ischémique était de 74,9 %. et celle de l'AVC hémorragique était de 25,1 %. Les facteurs de risque les plus courants pour d'AVC documentés chez les patients victimes d'un AVC dans un hôpital tertiaire de Enugu étaient le diabète, l'hypertension et l'âge de 65 ans et plus. Lorsque l'âge, la corrélation entre l'hypertension et l'AVC hémorragique était toujours significative. MOTS CLÉS: AVC ischémique, AVC hémorragique, Facteurs de risque, Nigeria.

Transplant tourism among kidney transplant patients in Eastern Nigeria.

BACKGROUND: Transplant tourism entails movement of recipient, donor or both to a transplant centre outside their country of residence. This has been reported in many countries; and has variously been associated with organ trade. The objective of this study is to determine the frequency and pattern of transplant tourism among transplant patients in Eastern Nigeria. METHODS: This is a non randomized cross sectional study. All kidney transplant patients who presented at Enugu State University Teaching Hospital Parklane Enugu and Hilton Clinics Port Harcourt in Nigeria were recruited. The clinical parameters including the transplant details of all the patients were documented. The data obtained was analysed using SPSS package. RESULTS: A total of one hundred and twenty six patients were studied, 76.2% were males with M:F ratio of 3.2:1 and mean age of 46.9 ± 13.3 years. Fifty four and 58.7% of the patients were managed in a tertiary hospital and by a nephrologist respectively before referral for kidney transplant. Only 15.8% of the patients had their kidney transplant without delay: finance, lack of donor, logistics including delay in obtaining travelling documents were the common causes of the delay. Ninety percent of the patients had their transplant in India with majority of them using commercial donors. India was also the country with cheapest cost ($18,000.00). 69.8% were unrelated donors, 68.2% were commercial donors and 1.6% of the donors were spouse. All the commercial donors received financial incentives and each commercial donor received mean of 7580 ± 1280 dollars. Also 30.2% of the related donors demanded financial incentive. CONCLUSION: Transplant tourism is prevalent in eastern Nigeria.

Prevalence and clinical and laboratory characteristics of kidney disease in anti-retroviral-naive human immunodeficiency virus-infected patients in South-South Nigeria.

Since the emergence of acquired immune deficiency syndrome (AIDS) about three decades ago, several renal disorders have been reported as common complications of human immunodeficiency virus (HIV) infection. These renal disorders result from diverse etiologies. The aim of this cross-sectional study was to determine the prevalence and clinical and laboratory characteristics of anti-retroviral-naοve HIV-infected patients with impaired kidney disorder in South-South Nigeria. This study was conducted on patients presenting at the University of Benin Teaching Hospital, Benin City in South-South Nigeria for six months. The patients' demographic data and clinical, hematological and biochemical parameters were assessed. Their glomerular filtration rate (GFR) was calculated and the protein excretion was assessed from the protein- creatinine ratio. Data were analyzed using statistical software program SPSS version 15.0. Three-hundred and eighty-three patients with a mean age of 35.39±8.78 years and a male: female ratio of 1:1 were studied; 53.3% had evidence of kidney disorder. The main clinical features in patients with kidney disorder were evidence of fluid retention, urinary symptoms, pallor and encephalopathy. The mean systolic and diastolic blood pressures were 115.33±17.17 and 72.33±14.31 mm Hg, respectively. The mean estimated GFR was 52.5 mL/min/1.73 m 2 . Patients with kidney disorder had higher proteinuria (P=0.001), lower mean CD4 cell count and packed cell volume (P=0.019 and 0.001, respectively). Kidney disorder is a common complication in HIV-infected patients, and they have clinical and laboratory anomalies. Screening of HIV/AIDS patients at the time of diagnosis will facilitate early diagnosis of kidney disorders in them.

Prevalence and correlates of chronic kidney disease among civil servants in Bayelsa state, Nigeria.

INTRODUCTION: Chronic kidney disease (CKD) has become a public health problem with rising incidence and prevalence world-wide. Despite the fact that Sub-Saharan Africa, including Nigeria appears to be badly hit by this epidemic, there is a paucity of data on CKD prevalence in these regions and where data exists, they are mostly hospital-based. OBJECTIVES: The present study was carried out to determine the prevalence and correlates of CKD in an urban civil service population in Bayelsa State, Nigeria. MATERIALS AND METHODS: A total of 179 civil servants in the Bayelsa State secretariat were screened for CKD during the World Kidney Day on March 2012. CKD was defined as estimated glomerular filtration rate <60 ml/min/1.73 m 2 body surface area and/or proteinuria. Socio-demographic data was obtained using interviewer-administered semi-structured questionnaire while anthropometric measurements were taken. Blood pressure (BP), urinalysis, serum urea and creatinine were also assessed. RESULTS: The prevalence of CKD in the study was 7.8%. Age >50 years was associated with CKD in univariate analysis but none of age, gender, body mass index, BP or hyperglycemia independently predicted it. CONCLUSION: The prevalence of CKD among Nigerian civil servants was fairly high and was associated with advancing age. Routine screening for CKD in this population is recommended.

Outcome and challenges of kidney transplant in patients with sickle cell disease.

Sickle cell nephropathy is a common presentation in patients with sickle cell disease. End-stage kidney disease is the most severe presentation of sickle cell nephropathy in terms of morbidity and mortality. Sickle cell disease patients with end-stage kidney disease are amenable to renal replacement therapy including kidney transplant. Kidney transplant in these patients has been associated with variable outcome with recent studies reporting short- and long-term outcomes comparable to that of patients with HbAA. Sickle cell disease patients are predisposed to various haematological, cardiorespiratory, and immunological challenges. These challenges have the potential to limit, delay, or prevent kidney transplant in patients with sickle cell disease. There are few reports on the outcome and challenges of kidney transplant in this group of patients. The aim of this review is to highlight the outcome and challenges of kidney transplant in patients with sickle cell disease.

Pregnancy in a 24 year old Nigerian woman with chronic kidney disease: challenges and outcome.

There is increasing incidence and prevalence of chronic kidney disease worldwide. The developing countries including Nigeria are facing greater challenges because of the prevailing poverty and high burden of infectious diseases. There are various prevalent co-morbid conditions that influence and are influenced by the status of the kidney function of the patient. These conditions pose some peculiar challenges and management of the challenges will determine the outcome. The aim of this report is to highlight the chalIenges of pregnancy in women with chronic kidney disease and possible outcome. We report a 24 years Nigerian woman diagnosed with chronic kidney disease who presented with 10 weeks gestation and deteriorating kidney function. Her management was associated with various challenges including non adherance to medications and not regular to follow up visits. She later developed ecclampsia and had intra uterine fetal death. She had various interventional measures including haemodialysis. She recovered kidney function appreciably but has defaulted follow up since discharge.

Analgesic nephropathy as a cause of end-stage renal disease in a 55 year-old Nigerian.

Analgesic nephropathy is a subtle but significant cause of chronic renal failure. There is paucity of data on analgesic nephropathy in Nigeria. This case presentation is to highlight the need to have high index of suspicion in patients at risk of developing analgesic nephropathy. In March 2009 a 55-year-old businessman was referred to the renal unit on account of azotemia by the hematologist who had hitherto managed the patient as a case of refractory anemia. The patient had osteoarthritis for over 10 years and was managed with several analgesic drugs over the same period. He was found to have features suggestive of analgesic nephropathy and had end-stage renal disease. He was commenced on appropriate therapy, and he had a live related kidney transplant six months later. Analgesic nephropathy is preventable and morbidity/mortality can be remarkably reduced with appropriate and prompt intervention.

Cardio-renal-anemia syndrome: a report of three cases.

Patients with chronic kidney diseases (CKDs) and cardiovascular diseases (CVDs) present with various degree of anemia. Anemia has been associated with poor outcome in patients with CKD and CVD. CVD is the commonest cause of morbidity and mortality in patients with CKD. CKD causes anemia and CVD, and this rapidly deteriorates when anemia is not corrected. This triad of CVD, CKD, and anemia has been termed cardio-renal-anemia syndrome. The objective of this study is to highlight the importance of cardio-renal-anemia syndrome, their relationship, and management. Three patients with various stages of CKD who presented with anemia and cardiovascular abnormalities are reported. The patients responded well to various interventional measures, with improvement in their clinical and laboratory parameters. Cardio-renal-anemia syndrome is an entity that should be identified. Early and appropriate intervention leads to better outcome.

Kidney transplant in a 26-year-old nigerian patient with sickle cell nephropathy.

Sickle cell nephropathy (SCN) is a common complication of sickle cell disease (SCD). It has variable presentation, ranging from hyposthenuria to end-stage renal disease (ESRD). Management of ESRD in SCD patients is froth with multiple challenges which has potential to impact negatively the outcome of the patient. Kidney transplant is the preferred renal replacement therapy in these patients. The objective of this case study is to report kidney transplant in a Nigerian young man with sickle cell nephropathy and to highlight the outcome and the challenges to kidney transplant in this patient. The index case is a 26-years-old sickle cell disease patient with ESRD complicated with cardiovascular, pulmonary, immunological, and infective challenges. These conditions were controlled, and the patient had a successful live-related kidney transplant. Kidney transplant is a viable option for sickle cell disease patients with ESRD.

Renal disease in HIV infected patients at University of Benin Teaching Hospital in Nigeria.

BACKGROUND: HIV related renal disease is a common occurrence in patients with HIV infection. It is the third leading cause of end stage renal disease among African-American males between the ages of 20 and 64 years in USA. Renal function impairment has been reported at all stages of HIV infection. The aim of this study is to determine the relationship between severity of renal function impairment and CD4 cell count in HIV infected patients. METHOD: HIV patients presenting at University of Benin Teaching Hospital Benin, City Nigeria from 1(st) January to 30(th) June 2007 were randomly selected and screened for renal functional impairment (RFI). Those with RFI detected by glomerular filtration rate < 60 ml/min/1.73 m(2) or urine protein creatinine ratio 3 200 were stratified into mild, moderate and severe RFI. Forty patients from each stratum and forty HIV infected patients with normal renal functions were recruited as subjects and control respectively. Their clinical and laboratory parameters were evaluated. The data obtained were analysed using SPSS vs 15.0. RESULTS: Of the HIV patients screened, 53.3% had renal functional impairment. of these, 40.2% had mild, 37.7% had moderate and 22.2% had severe impairment in their renal functions respectively Their mean age was 36.0 ± 8.8 years. The CD4 cell count was found to be 309.75 ± 268.71/ul, 188.45 ± 173.12/ul, and 141.10 ± 126.01/ul among subjects with mild, moderate and severe RFI respectively. The CD4 cell count in control group was 319.05 ± 248.41/ul. The difference was statistically significant. (p = <0.001). CD4 cell count had a significant positive correlation with GFR (r = 0.32, p = 0.042). However, there was a negative correlation between CD4 cell count and proteinuria but this was not statistically significant (r = 0.09, p = 0.173). CONCLUSION: Severity of RFI has a positive correlation with degree of immunosuppression in HIV infected patients.

Spectrum of Clinical Presentations in Human Immunodeficiency Virus (HIV) Infected Patients with Renal Disease.

HIV infection is a multiorgan disease with the kidney not spared. A variety of renal syndromes with varying clinical presentations has been reported amongst HIV infected patients. This study aims to highlight the spectrum of clinical presentations in HIV infected patients with renal disease. HIV infected patients presenting at University of Benin Teaching Hospital (UBTH) Benin City were the study population. A total of 383 patients were studied. Their biodata, clinical presentations and laboratory investigations including serum urea, creatinine and albumin, urine protein and creatinine were assessed. Their glomerular filtration rate (GFR) and protein urine excretion were calculated using six equations of modification of diet in renal disease (MDRD) and protein: creatinine ratio respectively. Patients were stratified according to their renal functions into normal, mild, moderate and severe renal function impairment. The data was analysed using statistical software program SPSS Vs 15.0. 53.3% of 383 patients screened had renal function impairment, 40.2% mild, 37.7% moderate and 22.2% severe impairment. Mean age was 35.6±8.3, 36.0±9.9 and 36.3±8.3 years for mild, moderate and severe renal function impairment (RFI) respectively. Easy fatigability was the commonest symptoms occurring in 47.5%, 30.0%, 37.5% and 22.5% of control, mild RFI, moderate RFI and severe RFI subjects respectively (p = 0.568). Oliguria, facial and body swelling occurred more in patients with RFI especially in patients with severe renal impairment. The difference is statistically significant (p = 0.046, 0.041, and 0.033 respectively). Pallor was the commonest clinical sign occurring in 32.5%, 50.0%, 35.0% and 62.5% of control and patients with mild, moderate, and severe RFI respectively; the difference was not statistically significant (p = 0.459). Ascites, facial puffiness and pedal oedema were commoner in patients with RFI especially those with severe RFI. The differences were statistically significant. (p = 0.048, 0.019, and 0.008 respectively). In conclusion spectrum of clinical presentations in HIV patients with renal impairment are many but few are specific to these patients.

Risk factors associated with congenital malaria in Enugu, South Eastern Nigeria.

There is paucity of data on the risk factors associated with congenital malaria in Nigeria. This study assessed the risk factors for congenital malaria in a population of neonates delivered at the University of Nigeria Teaching Hospital, Enugu, South Eastern Nigeria. It was a prospective cross-sectional study of neonates who were delivered in the institution from 2 April 2003 to 15 April 2004 as well as their mothers. Thick and thin blood films were made from maternal, baby and cord blood as well as the placenta for each mother/baby pair to determine malaria parasite density counts and for species identification. The maternal samples were obtained as soon as labour was confirmed while the cord and baby's blood as well as placental smears were taken within 1 h of delivery. Data analysis was by means of descriptive and inferential statistics as well as univariate and multivariate logistic regression at the 95% confidence level using the statistical software SPSS for Windows Version 10. A total of 658 mother/baby pairs were recruited into the study within the 13-month period. Out of this number, 625 mother/baby pairs completed the study and their data were subsequently analysed. A total of 356 (56.96%) mothers and 203 (32.48%) babies were smear positive for Plasmodium falciparum. On univariate logistic regression with presence or absence of the congenital malaria as the dependent variable, six out of the 13 putative risk factors tested were statistically significant. These were low compared with higher socioeconomic classes (OR = 1.41, 95% CI = 1.18 - 1.69, p = 0.00); low compared with normal birth weight (OR = 2.14, 95% CI = 1.39 - 3.30, p = 0.001); positive placental malaria parasitaemia (OR = 6.29, 95% CI, 4.73 - 8.37, p = 0.000), positive maternal blood malaria parasitaemia (OR = 5.04, 95% CI = 3.74 - 6.78, p = 0.000), positive cord blood malaria parasitaemia (OR = 26.87, 95% = 15.79 - 45.74, p = 0.000) and parity of 0 - 1 compared with other parities (OR = 1.31, 95% CI = 1.11 - 1.55, p = 0.002). On multivariate logistic regression, three of the six factors that were significant on univariate logistic regression remained significant. These were: positive placental malaria parasitaemia (OR = 2.55, 95% CI = 1.45 - 4.47, p = 0.001); positive cord malaria parasitaemia (OR = 18.90, 95% CI = 10.68 - 33.46, p = 0.000 and parity of 0 - 1 compared with other parities (OR = 1.66, 95% CI = 1.09 - 2.52, p = 0.02). It was concluded that the risk factors for congenital malaria identified in this study emphasise the need for effective preventive and curative treatment of malaria not only during pregnancy but also during delivery in malaria endemic areas. Additionally, congenital malaria should now rank high among the list of differential diagnosis of fever in the newborn in such endemic areas.
