Frequency of Type-2 diabetes mellitus in Nephropathic patients and comparison of mean magnesium levels in Nephropathic patients with and without Type-2 diabetes mellitus

Objective The objective of this study was to determine the frequency of Type 2 diabetes mellitus (T2DM) in patients with nephropathy (i.e. Chronic Kidney Disease Stage 1 to 3) and to compare the mean magnesium levels in diabetic nephropathic patients and non-diabetic nephropathic patients. Methods This cross-sectional study was conducted in department of Medicine, Mayo Hospital Lahore from August 2014 to February 2015. Using non-probability purposive sampling 200 nephropathic (Chronic Kidney Disease Stage 1 to 3) patients were selected. Patients were assessed for T2DM and divided in two groups on the basis of presence or absence of DM. Magnesium levels were recorded in both groups. Percentages, mean, standard deviation and unpaired t-test was used to assess the data. SPSS was used for analysis of information. Results Total number of cases were 200, 43.5% (n=87) out of them were between 25-50 years of age while 56.5% (n=113) patients were between 51-70 years. The Mean+SD was calculated to be 51.38+11.51 years. The male patients were 48.5 %(n=109) while 51.5 %(n=91) were females. The frequency of DM in patients with nephropathy was 25.5% (n=51). Comparison of mean magnesium levels in nephropathic patients with and without diabetes was done. The results showed nephropathic patients having diabetes had 1.54+0.301 mg/dL magnesium levels while cases without diabetes had 1.92+0.313 mg/dL levels of magnesium, p value was calculated as 0.001 showing a significant difference between the two groups. Conclusion The frequency of diabetes mellitus is higher among patients with nephropathy while on comparison of mean magnesium levels, nephropathic patients with diabetes had significant lower levels of magnesium as compared to without diabetes.
