[Frequency of diabetic microangiopathy in newly diagnosed diabetes mellitus in Conakry: late diagnosis and lack of screening].

INTRODUCTION

Diabetes morbidity is not only connected to a scarce therapeutic care. It is especially the fact of late diagnosis of diabetes, at a time where complications are already present. The aims were to estimate the frequency of microangiopathy observed at the time of diabetes diagnosis within diabetic patients received in Conakry University Hospital and to describe the clinical characteristics of patients who had this complication.

PATIENTS AND METHOD

We prospectively examined 116 patients [76 men (65.5%) and 40 women (34.5%); 11% type 1 diabetes and 89% type 2 diabetes] consecutively received and for whom known evolution of diabetes was lower or equal to three-months. All patients were interrogated (in search of cardiovascular risk factors), had a systematic check for retinopathy (exam done by ophthalmologist) or nephropathy (by measure of creatinine, urea and proteinuria).

RESULTS

Diabetic retinopathy was present in 29 cases (24.8%) and diabetic nephropathy in 9 cases (7.8%), one at the stage of chronic renal failure. The patients who had microangiopathy were older than the others (p = 0.003) and have more frequently Type 2 diabetes (p = 0.005). However, glycaemia level and cardiovascular risk factors (nicotine addiction, arterial high blood pressure, obesity and sedentary) were not statistically different between both groups.

CONCLUSION

Diabetic microangiopathy is frequent at the time of diabetes diagnosis in Guinea. Thus need for a check-up at the diabetes discovery time, as these results point the therapeutic choices and justify patient's compliance.
