Nephropathy is one of the complications occuring during diabetes diagnosed via microalbuminuria. From 1992 to 1999, five hundred and eighty seven (587) diabetic patients were recruited in groups A (n = 270) and B (n=317). Microalbuminuria was determined by immunonepheletry for A and immunoturbidimetry for B. The results pointed out respectively 15.5% and 20.19% pathological cases (NS). Considering the distribution of patients with microalbuminuria according to the type of diabetes there were 16.12% type 1 and 15.07% type 2 in group A against 22.60% and 18.13% in group B ; no stastically significant differences were observed either in the same group or from one group to another. These frequencies would reflect the situation in the nineties; they are lower than those encountered in other populations. Nevertheless monitoring is needed through a regular schedule to prevent nephropathy.
