The Effect of Dehydroepiandrosterone on Ovarian Reserve in Ovarian Damage Caused by Methotrexate

To determine the possible detrimental effects of multiple methotrexate doses has on the ovarian reserve and to determine the beneficial effects of dehydroepiandrosterone supplementation. The rats (n:24) divided into three groups; Group 1: control group, Group 2: dehydroepiandrosterone and methotrexate group (6mg/kg dehydroepiandrosterone dissolved in 0.1 ml sesame seed oil subcutaneously for ten days and 1mg/kg intramuscular methotrexate at the 1st, 3rd, 5th and 7th days) and Group 3: methotrexate group (1mg/kg intramuscular methotrexate at the 1st, 3rd, 5th and 7th day). The groups compared in regards to their histopathological ovarian damage scores and AMH values. It established that multiple methotrexate applications had a considerable effect on reducing vascular congestion in the ovarian tissue. Both in groups 2 and 3 AMH values found to be significantly lower. When this decline in the ovarian reserve examined comparatively; while both the group 2 and 3 reported having a considerable and continuous reduction in the AMH levels correlative to the control group; the primordial, primary and total follicle counts shown to stay statistically the same in the group 2 (

The role of pentraxin 3 as diagnostic value in classification of patients with heart failure

Objective: Pentraxin 3 (PTX3) is a new inflammatory marker that is the prototype of the long pentraxin group, while C-reactive protein (CRP) is the short pentraxin group. The aim of the present study was to investigate the clinical significance of plasma PTX3 and CRP levels in heart failure (HF). Materials and methods: The study included 22 male and 37 female patients with HF, and 23 healthy volunteers as the control group. Patients were divided into 4 groups (class I, II, III and IV) according to New York Heart Association functional class. Results: Plasma PTX3 and CRP levels were significantly elevated in HF patients compared to healthy controls. Comparing PTX3 levels in patient groups, statistically significant difference was found between class-I and class-II, class-III and class-Of patients (p = 0.009, p = 0.001, p < 0.001, respectively). There was a positive correlation between PTX3 and CRP levels (r = 0.369, p = 0.004). In receiver-operating characteristic (ROC) curves, area under the curve (AUC) values for PTX3 and CRP were 0.928 (p = 0.001) and 0.834 (p = 0.001), respectively. Conclusions: Plasma PTX3 levels are elevated in HF and might be used as diagnostic value in classification of patients with HF. It is still debated whether inflammation may be just a cause or a consequence of the disease. Therefore further work is needed to better understand in large populations of patients with HF.
