RESUMEN
OBJECTIVES: The aim of the study was to investigate the ability of the systemic inflammatory parameters to predict the discrimination of the phases of Peyronie's disease (PD). MATERIALS AND METHODS: Demographic, clinical, and laboratory data from 156 patients with PD were analyzed. A complete blood count (CBC) was obtained for every patient, and the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-eosinophil ratio (MER) were calculated for every men. Subsequently, patients were divided into two groups based upon the phase of the disease. RESULTS: The mean age was 51.9 ± 9.6 in all study population. The mean duration between symptom onset and patient evaluation was 4.2 ± 3.2 months in acute phase group, while it was 32.7 ± 31.7 months in chronic phase group (p < 0.001). There were no significant differences between the groups according to comorbidities such as diabetes, hypertension, lipid abnormalities, ischemic heart disease, smoking, and alcohol consumption. There was a statistically significant difference in NLR and PLR between two groups (p = 0.008, p = 0.008, respectively). NLR and PLR were significantly correlated with discrimination status in univariate analysis (p = 0.003, p = 0.005, respectively). Multivariate regression analysis revealed that NLR was the only independent risk factor for discrimination of the phases of PD (p < 0.001). The ROC analysis revealed a cutoff value of 1.8 (AUC 0.712, p < 0.001; sensitivity 61.1%; specificity 75.0%) for the NLR. CONCLUSION: Our study demonstrated that NLR could be helpful to differentiate the chronic phase from the acute phase in patients with PD. Therefore, NLR could be used as an objective biomarker to the management of the disease and choosing the appropriate treatment.

OBJECTIVE: Nephrotoxicity is a major complication of gentamicin (GEN), which is widely used in the treatment of severe Gram-negative infections. As we know, treatment with nebivolol has been shown to decrease renal fibrosis and glomerular injury as well as improve endothelial dysfunction. Therefore, we evaluated the potential protective effect of nebivolol (NBV) against GEN-induced nephrotoxicity in rats. MATERIAL AND METHOD: Twenty-four rats were randomly divided into four groups: control group (Group 1); rats intraperitoneally injected with GEN (100 mg/kg/day; Group 2); rats treated with GEN plus distilled water (Group 3); and rats treated with GEN plus NBV (10 mg/kg/day; Group 4). After 15 days, the rats were sacrificed, their kidneys taken, and blood analysis performed. Tubular necrosis and interstitial fibrosis scores were determined histopathologically in a part of kidneys; nitric oxide (NO), malondialdehyde (MDA), and reduced glutathione (GSH) levels were determined in other part of kidneys. RESULTS: The GSH levels in renal tissue of only GEN-treated rats were significantly lower than those in control group, and administration of NBV to GEN-treated rats significantly increased the level of GSH. The group that was given GEN and NBV had significantly lower MDA and NO levels in kidney cortex tissue than that given GEN alone. Despite the presence of mild tubular degeneration, the rats treated with GEN+NBV showed a less severe tubular necrosis, and their glomeruli maintained a better morphology compared to GEN group. CONCLUSION: NBV exerts antioxidant, anti-inflammatory and antifibrotic effects on GEN-induced kidney damage by reducing oxidative stress in rat model (Tab. 3, Fig. 2, Ref. 68).
