The role of inflammatory parameters (neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and monocyte-to-eosinophil ratio) in patients with Peyronie's disease.

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.

Protective effect of hydrogen sulfide on experimental testicular ischemia reperfusion in rats.

AIM: Testicular torsion is an urgent urological condition. Ischemia-reperfusion (I/R) processes that occur after detorsion as a treatment for torsion are caused by testicular injury. The purpose of our study is investigating the protecting effect of hydrogen sulfide (H2S) on the testicular ischemia reperfusion injury. MATERIALS AND METHODS: Thirty-eight Wistar-Albino rats were divided randomly into 6 different groups: Control (6); sham (6); IR-E (6)-2 h of torsion and 4 h of reperfusion; IR-E + H2S (6)-in addition to the IR-E group, 75 µmol/kg of sodium hydrogen sulfide (NaHS) was administered intraperitoneally 30 min before reperfusion; IR-L (7)-2 h of torsion and 24 h of reperfusion; IR-L + H2S (7)-in addition to the IR-L group, 75 µmol/kg NaHS was administered intraperitoneally 30 min before reperfusion. Biochemically, nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD), reductive glutathione (GSH), and tumor TNF-α levels were measured in the testis. Serum TNF-α levels were also measured. Hematoxylin and eosin (H & E) was used for histopathological staining and microscopic findings were examined. The Johnsen score was performed to assess spermatogenesis activity in the testis. Apoptosis protease activating factor-1 (Apaf-1) and inducible nitric oxide synthase (iNOS) activity were evaluated immunohistochemically as well. Statistical analyses were made by the Chi-squared test and one-way analysis of variance. RESULTS: MDA and NO levels were significantly increased in the IR-L group compared with sham and which decreased by the addition of H2S treatment to the IR-L group (p < 0.05) in biochemical evaluation. GSH vs SOD levels were decreased in the IR-L group compared with sham and which increased by the addition of H2S treatment to the IR-L group, but this correlations were not statistically significant (p > 0.05). Tissue and serum TNF-α levels were significantly increased in the IR-E group compared with sham and which decreased by the addition of H2S treatment to the IR-E group. Johnsen score was the lowest in IR-L group (p < 0.05). Apaf-1 and iNOS activity were significantly increased in the IR-L group compared with sham and which decreased by the addition of H2S treatment to the IR-L group (p < 0.05) in immunohistochemical evaluation. CONCLUSIONS: First, the authors would like to say that H2S treatment is protective and it is against ischemia reperfusion injury in testicular torsion. The anti-inflammatory, antioxidant, and antiapoptotic properties of H2S caused protective effect as shown in this study.
