Association of Serum Prolactin Concentrations with Renal Failure in Diabetic Patients

Abstract

Background and aims: Diabetes is one of the causes of end-stage renal disease, so that about 70% of all diabetic patients have nephropathy. Prolactin is a hormone that is affected by diabetes but the interaction between diabetes and prolactin has not been understood properly. This study aimed to evaluate the relationship between changes in serum prolactin levels in diabetic patients with renal failure. Material and methods: In this study 223 individuals were participated and after assessment of inclusion/ exclusion criteria 189 individuals were evaluated. Finally, the individuals were divided into three groups: Control (C), Diabetic (D), and Diabetic Nephropathy (DN). Blood samples were collected between 8.00 a.m. and 12.00 a.m. for measurement of prolactin levels and biochemical analysis. Results: The results showed that sodium, potassium, urea, creatinine and prolactin significantly increased in DN group compared to control individuals (P< 0.001). The prolactin levels were significantly decreased in the group of patients with diabetes (P< 0.001). Conclusion: The results of the current study indicated that serum prolactin level decreased in diabetes while it increased in diabetic nephropathy.

Macrophage migration inhibitory factor antagonist (p425) ameliorates kidney histopathological and functional changes in diabetic rats

“…Diabetic nephropathy (DN) is the most common cause of chronic kidney disease and is one of the most important long-term complications related to diabetes. Although the DN is conventionally viewed as a nonimmune disease, numerous evidence show that inflammatory mechanism may play a pivotal role in its development and progression 1 - 3…”

Immunomodulator Drug (IMODTM) and Exercise Improve Cardiac Oxidative Stress and Antioxidant Balance in Diabetic Rats

“…Type 1 diabetes is associated with the destruction of insulin-producing pancreatic β-cells (1). Diabetes, with complex and not fully understood pathophysiology, increases the risk of cardiovascular complications at least 10-fold (2,3). Diabetes-induced impairments in cardiac function and structure are termed as diabetic cardiomyopathy (DCM) (4,5).…”
