Introduction: One of the biological markers for monitoring glycaemic control in diabetic patients is glycated protein. The definition of a reference method to improve the accuracy of measurement tools is necessary. The aim of our study was to assess the glycemic control of diabetic patients based on glycated hemoglobin. Patients and Method: This is a descriptive cross-sectional study conducted in April 2021 at the national university hospital center (CNHU-HKM) of Cotonou. All patients who consulted during the period and who gave their consent were included. After collecting the blood samples according to the classical standards of the pre-analytical phase, we measured the blood glucose level and the HbA1c. Results: The mean blood glucose level of the patients was 1.52 ± 0.16 g/L with extremes of 0.80 g/L and 3.5 g/L. The mean HbA1c proportion was 8.39% ± 0.60% with a minimum and maximum value of 5.40% and 16% respectively. We also noted that the mean body mass index (BMI) of the patients was 28.61 ± 1.46 Kg/m 2 with extremes of 17.50 Kg/m 2 and 46.02 Kg/m 2 . Oral anti diabetic and hygienic-dietary measures were used by 44 patients (80%) and hygienic-dietary measures (HDM) only used by 9.09%. A frequency of 87.53% of patients had at least one degenerative complication. Retinopathy was the most observed degenerative disease (36.36%) followed by cardiovascular disease (25.45%). Conclusion: This study showed that there is a poor correlation between fasting blood glucose and glycated haemoglobin levels, which could be due to several biological and clinical reasons. It also showed that despite the respect of hygienic dietary measures and a well conducted treatment, it is difficult to obtain a satisfactory glycemic balance in obese patients.

Diabetes mellitus is a disease of great frequency and is a major public health problem. Several complications can occur during the course of diabetes such as diabetic nephropathy, which starts with microalbuminuria in diabetic patients. This was a cross-sectional and analytical study which took place from 23 September to 23 December 2021 in the Endocrinology-Metabolism-Nutrition Department of the CNHU-HKM of Cotonou, Benin. We carried out an exhaustive census of the patients. Type 2 diabetic patients were included in the study, and 24-hour microalbumunuria, fundus examination and assessment of complications were performed. We identified 145 type 2 diabetic patients of whom 44 had positive microalbuminuria, i.e. a prevalence of 30.3%. There were 61 men and 84 women with a sex ratio of 0.72. The mean age was 59 years with extremes of 26 and 85 years. The complications identified in diabetics with positive microalbuminuria were Neuropathy (43.2%), Nephropathy (22.7%) and Retinopathy (20.5%). Factors associated with microalbuminuria in diabetics were: age, occupation, hypertension, diabetes imbalance, erectile dysfunction. Conclusion: Microalbuminuria is common in type 2 diabetes. It should be managed early to slow the progression of kidney disease to the end stage.

Diabetic peripheral neuropathy (DPN) is a common complication of diabetes.The main objective of the study was to determine the prevalence of diabetic peripheral neuropathy and associated factors in diabetics in the University Clinic of Endocrinology Metabolism Nutrition of the CNHU-HKM, Cotonou, Benin 2021. This was a cross-sectional, analytical study that ran from 23 September to 23 December 2021. Admitted diabetic patients seen in consultation during the study period were included. The DN4 tool was used as the basis for data collection. Data analysis was performed using R software version 3.6.1. Multivariate analysis was used to identify factors associated with DPN. Out of 155 diabetics, 54 patients had diabetic peripheral neuropathy, a prevalence of 34.8%. The average age of our patients was 56.8 years and 56.8% were female. Of the patients, 54.7% had unbalanced diabetes. An association between DPN and gender (p = 0.022), occupation (p = 0.004), education (p = 0.011), hypertension (p = 0.017), smoking (p = 0.031), diabetic imbalance (p = 0.001), diabetic retinopathy (p = 0.020) and dyslipidaemia (p = 0.015) was observed. DPN was also associated with erectile dysfunction in men (p = 0.001). Conclusion: Diabetic peripheral neuropathy is common (34.8). Its occurrence is indicative of the presence of associated factors.

Aim: To determine the prevalence of peripheral arterial disease and its risk factors in type 2 diabetic outpatients. Materials and Methods: It was a descriptive and analytical cross-sectional study, which included 146 diabetic out patients seen. Peripheral arterial disease (PAD) has been accessed using Ankle-Brachial Index and Arterial Doppler Ultrasound . PAD was defined by an ABI value ≤ 0.9 in either of the legs Data management and analysis were performed using Epi-Info software. A p value <0.05 was considered significant. Results: The overall prevalence of peripheral arterial disease was 62.3%. Factors statistically associated with peripheral arterial disease were age (p=0.009), duration of diabetes greater than 10 years (p=0.006) and presence of peripheral neuropathy (p=0.0005). Conclusion: The prevalence of peripheral arterial disease is high in type 2 diabetic outpatients. A systematic screening and suitable management should be done in order to prevent cardiovascular events often associated.
