ABSTRACT
Background: Diabetes mellitus (DM) and its complications are on the increase especially in the developing countries with significant negative economic consequences on individuals, families and health systems. Objective: We, therefore compared albumin/creatinine ratio, microalbuminuria, and HbA1c among subjects of varying degree of complications with controls to ascertain if they can serve as markers of diabetic chronic complications to enhance early detection of chronic complications amongst diabetes mellitus patients in developing countries. Methods: 109 type 2 DM subjects (47 males and 62 females) and 100 non-DM controls of the same age range (40-80 yrs) were recruited for this study. The chronic complications found were: nephropathy, retinopathy, coronary artery disease, cerebrovascular disease, peripheral vascular disease and diabetic foot. These were further classified into micro vascular complications (nephropathy and retinopathy) and macrovascular complications (Coronary Artery Disease, Cerebrovascular Disease, Peripheral Vascular Disease and diabetic foot).Out of these 109 DM subjects, 36 were without chronic complications, 37 have microvascular complications only and 36 have a combination of microvascular and macrovascular complications. HbA1c, Urine microalbumin and creatinine were analysed using standard methods. Results: The mean levels of HbA1c, Microalbuminuria and albumin-creatinine ratio were significantly higher in DM subjects when compared to the control (p<0.05). Microalbumin, albumincreatinine ratio, and HbA1c were significantly higher in DM subjects with chronic complications than those without complications (p<0.05). However, DM subjects with both macro and micro complications had significant higher level of urine microalbumin, albumin-creatinine ratio, and HbA1c than those with microvascular complications only (p<0.05). Subjects aged 40-45 years had significant (p<0.01) albumin/creatinine ratio than subjects aged 51-55yrs as well as those >60 years. The male subjects had a significant (p<0.01) albumin/creatinine ratio and microalbumin respectively on comparing to their female counterpart Conclusion: Albumin-creatinine ratio is a simple, and less cumbersome tool which could serve as a predictor of complications in type 2 diabetes mellitus.
ABSTRACT
BACKGROUND AND OBJECTIVES: Various clinical and hematological indices have been used to assess the severity of Sickle Cell Anemia (SCA), however biochemical indices are lacking. Hepatomegaly has been a frequent finding in SCA and its persistence has been associated with increased disease severity. The association between hepatic enzymes and disease severity in SCA is undefined. This study was therefore designed to look at the association between clinical severity and hepatic enzymes in SCA subjects with persistent hepatomegaly (that is, lasting more than six months) in order to determine a possible role for hepatic enzymes as a biochemical index of severity. MATERIALS AND METHODS: Serum levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (SAP) and gamma-glutamyl-transferase (GGT) were determined in two groups of SCA subjects and in hemoglobin genotype AA (HbAA) controls. SCA group comprised of 37 subjects with persistent hepatomegaly equal to or greater than 10 cm (below right coastal margin) while the second group comprised another 38 SCA subjects without palpable hepatomegaly. 40 individuals with hemoglobin genotype AA served as control for both groups. Clinical and hematological parameters of severity which included steady state haematocrit, number of transfusions per year, number of crises per year and percentage HbF level were determined and scored in a manner similar to the Glasgow coma scale. Results obtained were analyzed with the aid of statistical package on EPI-INFO version 6.02. RESULTS: There was a significant increase in serum ALT, ALP and GGT levels in SCA with persistent hepatomegaly over those without hepatomegaly (p < 0.05, p < 0.05 and p < 0.01 respectively). All the index scores and the final aggregate severity scores were also significantly higher in SCA subjects with persistent hepatomegaly. Only GGT demonstrated a fairly positive and significant correlation (r = 0.46, P < 0.05) with increased clinical severity among the hepatic enzymes. CONCLUSION: Elevated serum level of GGT in SCA during steady state is suggestive of increased disease severity.
