Abstract: Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia. In Cameroon, the traditional treatment of this pathology is based on the use of Propolis. The present study aims to evaluate the antidiabetic and antioxidant properties of the ethanoic extract of Meiganga propolis (Adamawa Region, Cameroon). To confirm the different properties of this extract, the glycaemia, lipid profile and oxidative stress parameters of different groups of animals were assessed in a type 2 diabetes model induced by the Hypercaloric Sucrose Diet combined with dexamethasone. Simultaneous administration of the ethanolic extract of Meiganga propolis (EEMP 300 mg/kg) and the hypercaloric sucrose diet to rats for 30 days prevented a significant increase in fasting blood glucose levels compared with animals in the diabetic control group, whose fasting blood glucose levels were 78.25 ± 2.29 and 156.5 ± 2.75 mg/dL respectively on day 30. In terms of lipid profile, the administration of propolis extract (300 mg/kg) prevented a significant increase in LDL-cholesterol and triglyceride levels compared with animals in the diabetic control groups. The values were 27±2.71 mg/dL and 97.8±2.92 mg/dL for LDL-cholesterol. In terms of oxidative stress, simultaneous administration of propolis extract (300 mg/kg) and a high calorie diet to rats for 30 days prevented a significant increase in malondialdehyde (MDA) and increased superoxide dismutase (SOD) levels compared with animals in the diabetic control group. Values for this superoxide dismutase in the liver were 81.72 U/g of organ for EEMP 300 mg/kg and 58.6 U/g of organ in the liver of diabetic rats. These results justify the use of ethanoic extract of Meiganga propolis in the prevention of type 2 diabetes in Cameroon.

Abstract: Introduction: Endogenous Cushing's syndrome (CS) is a known cause of secondary osteoporosis, characterized by a loss of bone mass and density. Cushing's osteopathy is one of it’s most severe complications. Abnormal bone turnover, decreased bone mineral density (BMD), and increased fracture risk are common effects of glucocorticoid excess. Objectives: The aim of our work is to determine the bone densitometric profile of patients followed for Cushing's disease, to define the characteristics of osteoporosis and osteopenia in these patients, and to analyze the factors influencing BMD. Materials and methods: This is a retrospective descriptive study involving patients followed for Cushing's disease in the endocrinology-diabetology department of the public hospital establishment (EPH) of Bologhine-Algiers, during a period of 10 years, going from the January 2013 to January 2023. Results: 58 patients were followed during this period with an average age was 34 years, with a clear female predominance and a sex ratio of ≈ 4. Average Z score was (-1.6) at the vertebral level and (-1.09) at the femoral level. Osteoporosis was found in 44.8% (n = 26) patients and osteopenia in 37.9% (n = 22), while normal BMD was found in 17.24% (n = 10). Note that Z-score values were significantly lower at the lumbar spine than at the femoral neck. No significant difference in BMD was found between eumenorrheic and hypo-/amenorrheic females with Cushing's disease. Our study demonstrated a significant negative correlation between morning plasma cortisol and BMD. While there is a significant positive correlation between BMD and ACTH concentration in CD patients, BMD at the lumbar spine and femoral neck also had a significant positive correlation with weight and BMI. Conclusion: Early detection and management of CS are essential to reduce bone complications. BMD examinations should be performed to enable rapid recognition and intervention for osteoporosis. Lumbar bone loss occurs earlier and more extensively.
