Diabetic nephropathy (DN) has a steadily increasing prevalence, particularly because of the increase in sedentary lifestyle and obesity. It is defined as the persistent presence of albuminuria in a diabetic patient and requires early management to prevent progression to end-stage renal failure. The purpose of this work is to describe the epidemiologic profile and the progression of DN for the first time in a southern Moroccan region: Guelmim Oued noun - Moroccan Sahara.Patients and methods: It is a retrospective study conducted at the 5th military hospital in Guelmim and including all diabetic patients seen in nephrology consultation between January 2015 and December 2018. We collected the following parameters of our patients: demographics, comorbidities, prescribed treatments and biological data (Albuminuria, renal function and glycated hemoglobin) during their nephrology follow-up.Résults: During the study period 267 diabetic patients were included among 1042 patients, which represented 25.9% of the nephrology consultation activity. Their average age was 64.3 years with a slight male predominance (60%) and only two patients had type 1 diabetes. At the first nephrology consultation the average duration of diabetes was 14.6 years, 61 (22.8%) patients were on diet alone, 95 (35.5%) on oral antidiabetic drugs (OADs), 94 (35.2%) on insulin and 35 (13%) on OAD and insulin. Half the patients were hypertensive and 107 (40%) already had a cardiovascular complication (arterial disease, coronary artery disease or stroke). The average initial albuminuria was 388 mg/24h and the average glomerular filtration rate (GFR) was 67 ml/min ; 115 (43%) patients being in renal failure. 46 (17%) patients had no renal function assessment during their previous follow-up and only 139 (52%) were on renin-angiotensin system inhibitors (RASIs). After 12-month-follow-up in nephrology, the average GFR was 70 ml/min and 64 ml /min after two years.Conclusion: Diabetic nephropathy accounts for at least a quarter of nephrology consultation activity in the region of Guelmim Oued Noun. It is characterized in this context by the delay in treatment using renin angiotensin system inhibitors and late nephrology referral hence the need to strengthen preventive strategies in this region especially continuous training. |
