Screening for Chronic Kidney Disease in Type 2 Diabetic Patients: Single Centre Study

Abstract Background Diabetes mellitus is the most common cause of chronic kidney disease in the world, leading to multiple complications including end-stage renal disease, cardiovascular disease and even death so, Screening is an important strategy to address the burden of CKD in diabetic population. International clinical guidelines recommend CKD screening for individuals with risk factors such as diabetes, using laboratory assessments of glomerular filtration rate (GFR) and urine albumin excretion. Objective This study describes the implementation and outcomes of screening programme for chronic kidney disease in type 2 diabetic patients to assess the burden of renal disease in diabetic population. Patients and Methods The present study included two hundred type 2 diabetic patients complicated with diabetic nephropathy. Fifty five percent of the studied patients were males. Age ranged from 42 to 82 years with mean ± SD of 60.09 ± 8.55 years. They were screened in Alagouza Hospital for CKD by using urinary ACR and average eGFR. Patients with CKD were further investigated for extrarenal diabetic complications as PVD, amputation and cardiovascular complications by using LL arterial duplex and echocardiography. Results As regard diabetic complications, nephropathy came in the 1st rank with 106 patients (53%) presented with either average eGFR<60 ml/min/1.73 m2(10.5%), ACR >30 mg albumin/gm creatinine (30%) or both(12.5%). That was followed by history of neuropathy which represented 44.5% of the studied patients. Retinopathy evidenced in fundus examination compromised about 34.516% out of our studied population. Patients with past history of stroke represented 17.5% of the studied population Peripheral neuropathy was more common in patients with nephropathy 69.7 % (n = 62) (4 patients with decline eGFR, 36 patients with albuminuria and 22 patients with both), compared to only 30.3 % (n = 27) non- nephropathic diabetic patients gave positive history of neuropathy. retinopathy was more common in patients with nephropathy (11 patients with declined GFR, 25 patients with albuminuria and 25 patients with albuminuria and declined GFR), versus only 8 patients in among the non-nephropathic diabetic patients had retinopathy evidenced in fundus examination. Stroke was more common among patients with nephropathy (4 patients with decline eGFR, 6 patients with albuminuria and 12 patients with albuminuria and declined eGFR), versus 13 patients with positive stroke history in non- nephropathic diabetic patients. Patients with nephropathy were further investigated for the presence of extra renal diabetic complications as PVD and cardiovascular complications. Arterial LL duplex revealed PVD in 32.1% (34 patients) with 3 patients underwent amputation. As regard cardiovascular complications, 17.9 % (19 patients) were found to have abnormal findings in echocardiography examination including heart failure and ischemic changes. Conclusion From our study, we showed the high burden of diabetic complications among the patients with type 2 diabetes especially renal diabetic complications. Therefore, screening of diabetic nephropathy in patients with type 2 diabetes mellitus can help in early treatment and avoid its more serious complications not only the progression to ESRD but also development of other extra-renal diabetic complications.
