Conclusions
1. The finasteride treatment of adult male rats led to a decrease in androgen receptor expression and its cellular translocation within the kidney cortex.
2. The pathomorphological changes (glomerulosclerosis, tubulosclerosis, dysplastic glomeruli, and tubules with lumen dilatation) in rats’ kidneys with disturbed steroid hormone imbalance were associated with the diminished expression of intracellular junctional proteins.
3. The changed apoptotic/proliferating ratio of nephron cells and the increase in the numberof lymphocytes in the area of pathologically altered convoluted tubules were accompanied by impaired androgen/estrogen homeostasis.
Although studies of exogenous DHT supplementation in animals previously receiving finasteride have not been performed, it can be suggested that these described evidences from the animal model of experiment could indicate that the patients with renal dysfunction or following renal transplantation with androgen supplementation or with pharmacologically (i.e., by finasteride) induced DHT deficiency should be under special control and covered by extended diagnostics, due to the potential adverse effect of DHT deficiency on the progression of kidney disease.
