Medical causes of death in a teaching hospital in South‑Eastern Nigeria: A 16 year review

Background: Most developing regions of the world are undergoing gradual epidemiological transition resulting in high burden of both communicable and noncommunicable diseases. This affects the pattern of death in this region.Objective: The objective of this study is to determine the causes of death in the medical wards of the University of Nigeria Teaching Hospital, Ituku/Ozalla, Enugu, South‑East Nigeria from 1995 to 2010.Materials and Methods: Data were collected retrospectively from January 1995 to December 2010.Statistical Analysis Used: Statistical Package for Social Sciences (SPSS Inc. Chicago, IL, USA) version 17.0 was used. Simple descriptive statistics were done. Student’s t‑test was used to compare means of continuous variables, while Chi‑square test was used to test significance of differences between two proportions.Results: The mortality rate was 22.8% (6250/27,514) admissions. The male to female ratio was 1.7:1. Infections (20.2%) were the most common cause of death. However, chronic kidney disease was the single most common disease entity causing death (12.3%). Other important causes of death in order of prevalence were cerebrovascular accident (10.5%), acquired immune deficiency syndrome and tuberculosis either alone or as co‑infection (10.3%), heart failure (8.8%), chronic liver disease (7.0%), septicemia (6.5%), respiratory failure (5.3%), diabetes mellitus (4.6%), cardiac arrhythmias (2.9%), and primary liver cell carcinoma (2.7%). There were few deaths from tetanus, malaria, typhoid fever, and coronary artery disease.Conclusion: Mortality is high in our medical wards and reflects the emerging trend of mixed disease spectrum comprising communicable and noncommunicable diseases.Keywords: Chronic kidney disease, infections, medical wards, mortality, Nigeri

Pattern of cancer deaths in the medical wards of a teaching hospital in South East Nigeria

Background: Cancers are emerging public health problems in developing countries like Nigeria. The epidemiological shift and aging population make cancers a challenge.Objective: We set out to describe the pattern of death due to cancer in our medical ward. The hospital is one of the premier hospitals covering the South East zone of Nigeria.Materials and Methods: We retrospectively reviewed the case notes and death certificates of all who died of cancer in our adult medical wards for 16 years (January 1995 to December 2010).Statistical Analysis Used: Statistical Package for Social Sciences (SPSS Inc. Chicago, IL) version 17.0 was used.Results: Twenty seven thousand, five hundred and fourteen patients were admitted into the medical wards. Six thousand, two hundred and fifty died. Out of the 6250 deaths, cancers accounted for 7.6%. Male to Female ratio was 2.4:1. The mean age at death was 43.7 ± 17.4 years. The mean age at death in both sexes was similar (42.9 ± 17.5 for men and 45.7 ± 17.0 years for women), P = 0.109. Primary liver cell carcinoma was the most common cause of death among men (40.8%), while cancer of hematopoietic organ was the most common in women (48.7%). The overall fatality rate was 1.7% (477/27 514) of medical admissions. Younger and middle age groups were most commonly affected in both sexes. Conclusion: Since the most productive age groups were affected, governments in developing countries should as a matter of urgency put in place adequate cancer preventive and curative services.Keywords: Cancer, mortality, medical wards, South East NigeriaNigerian Journal of Clinical Practice • Oct-Dec 2013 • Vol 16 • Issue

Prevalence of CKD-MBD in pre-dialysis patients using biochemical markers in Enugu, South-East Nigeria

Background: As kidney function declines, there is a progressive deterioration in mineral homeostasis with disruption of normal serum and tissue concentration of phosphorus and calcium, and changes in circulating levels of hormones-parathyroid hormone (PTH), calcitriol (1,25(OH)2 D), and Fibroblast growth factor-23 (FGF-23).Objective: This study was aimed at determining the prevalence of markers of CKD-MBD in pre-dialysis patients.Methods: We evaluated consecutively 168 subjects made up of 85 CKD patients and 83 healthy controls, who were attending the renal clinics and medical outpatient of University of Nigeria Teaching Hospital,  Enugu. GFR was estimated and serum calcium, phosphorus, alkaline phosphatase, PTH, and 25(OH) D levels assayed.Results: The prevalence of various mineral bone disease abnormalities were 70% hyper-phosphatemia, 85% hyper-parathyroidism, and 100% low levels of 25 (OH) D among the patients. Estimated GFR  correlated negatively with both serum phosphorus, and PTH. Age of the patients ranged from18-76 years with a male to female ratio of 1.7:1. Chronic Glomerulonephritis (CGN), hypertension and diabetes mellitus caused CKD in 75% of the patients. There was no significant decrease in serum calcium levels of patients compared to controls. The patients did not have pathologically raised alkaline phosphatase, although their mean level was significantly higher than that of the control group.Conclusion: Low 25 (OH) D levels (insufficiency/deficiency), hyperparathyroidism, and hyper-phosphatemia were the obvious markers of CKD-MBD in our pre-dialysis patients. These should be evaluated at presentation in these patients.Key words: CKD-MBD, Predialysis, biochemical markers, Southeast Nigeria

Left ventricular hypertrophy in renal failure review

Renal failure is becoming increasingly common in our enironment. Advances in management like availability of dialysis and transplantation is prolonging the live of patients. As a consequence complication are increasingly being encountered. Cardiovascular complication is one of the commonest; and left ventricular hypertrophy is one of the major cardiovascular complications of end stage renal failure. It is an independent predictor of survival in patients with chronic renal failure and is present in a large number of patients entering maintenance haemodialysis. This review summarizes the occurrences of left ventricular hypertrophy, its pathomechhanism, clinical significance, evaluation and interventional strategies. This information is useful to us as we grapple with this problem.
