RESUMO
OBJECTIVES: This study aimed to investigate the prevalence of sexual disorders in stage 2 - 5 chronic kidney disease (CKD) during predialysis and its relationship with laboratory parameters. METHODS AND RESULTS: This cross-sectional study included 110 predialysis patients and 110 healthy controls admitted to clinics. The International Index of Erectile Function (IIEF) and Female Sexual Function Index (FSFI) were used. Sexual dysfunction was detected in 76% of female patients and 31.4% of the control group, and the FSFI total and subscale scores of the patients were significantly lower than those of the control group. The frequency of erectile dysfunction in male patients and controls was 56.7% and 33.3%, respectively. The erectile function, sexual satisfaction, and overall satisfaction scores on the IIEF scale were significantly lower than those in the control group. Low glomerular filtration rate, high calcium levels, increased C-reactive protein, anemia, and metabolic acidosis in male and female patients, and testosterone deficiency in male patients were associated with sexual dysfunction. In multiple regression analysis, eGFR was the only independent variable associated with sexual dysfunction. Luteinizing hormone (LH) and prolactin levels increased as the disease progressed in men and women with sexual dysfunction, while testosterone levels decreased in male patients. Low testosterone levels were related to erectile dysfunction. The increase in parathormone and prolactin levels was related to loss of libido in the male and female patient groups. CONCLUSION: Metabolic acidosis and low eGFR appear to be the most important risk factors contributing to sexual disorders in patients with CKD.
RESUMO
OBJECTIVE: To investigate the effects of lipoic acid and methylprednisolone on nerve healing in rats with traumatic facial paralysis. MATERIALS AND METHODS: The rats were randomly divided into four groups, with six rats in the control group and eight each in the remaining three groups. The buccal branch of the facial nerve in all groups except the control group was traumatized by a vascular clamp for 40 minutes. Group 1 was given lipoic acid (LA), Group 2 was given methylprednisolone (MP), and Group 3 was given lipoic acid and methylprednisolone (LA + MP) for one week. Nerve stimulus thresholds were measured before trauma, after trauma and at the end of the one week treatment period. RESULTS: When the groups were compared with each other, post-treatment threshold levels of LA + MP were significantly lower than LA. Although post-treatment threshold levels of LA and MP were still higher than the control group, there was no significant difference between LA + MP and control values (p > .05). CONCLUSION: Lipoic acid has a positive effect on nerve healing and can enhance the effect of methylprednisolone treatment. It is a good alternative in cases where methylprednisolone cannot be used.
