[Renal failure in Tunisian patients with type 2 diabetes: frequency and related factors].

Background: Frequent screening of renal failure and good glycaemic control in diabetic patients can avoid this severe complication.

Aim: To evaluate the frequency of renal failure and the associated risk factors among type 2 diabetic Tunisian in-patients. Glomerular filtration rate was estimated using the Cockcroft-Gault formula.

[Factors influencing homocysteineamia in type 2 diabetic patients].

Previous studies have suggested that hyperhomocysteinaemia (Hcy) could be a strong and independent cardiovascular risk factor. Many factors could influence the serum concentration of Hcy such as vitamin B 12, folic acid, renal failure, hypothyroid status, ovarian failure and cancers. So the aim of our study was to evaluate the prevalence of hyperhomocysteinaemia among 54 type 2 diabetic patients and to study, its relationship with vitamin B12, folic acid and Metformin.
