Relationship between psoriasis and urolithiasis

The aim of the present study was to investigate whether patients with psoriasis are prone to urolithiasis. Prospective analysis of 67 patients diagnosed as psoriasis (PS group) and 65 volunteers who had never been diagnosed as psoriasis (NPS group) was performed. The levels of oxalate, citrate, calcium, uric acid, magnesium, creatinine, and sodium were evaluated by analyzing the 24-h urine samples. Stone events were detected in 13 patients (19.4%) in the PS group and in five participants (7.7%) in the NPS group, respectively (P < 0.05). The median value of 24-h citrate was significantly lower in the PS group than in the NPS group (P = 0.029). The median value of 24-h urine uric acid was significantly higher in the PS group than the NPS group (P = 0.005). Hypernatriuria was significantly higher in the PS group (P = 0.027). Hyperuricosuria was detected in the 10.4% and 1.5% of patients who had severe and mild disease, respectively (P = 0.027). Patients with psoriasis are more prone to urolithiasis. Hypocitraturia, hyperuricosuria, and hypernatriuria were the main metabolic abnormalities detected in psoriasis. Hyperuricosuria has been associated with the severity of the disease.

The Relationship Between Coronary Collateral Circulation and Serum Adropin Levels

Objective Coronary collateral circulation (CCC) are vascular structures that limit the infarct area, protect left ventricular function, and reduce the frequency of arrhythmia and mortality during myocardial ischemia and infarction. In this study, we examined the relationship between the development of CCC and serum adropin levels, which has been shown in previous studies to regulate endothelial functions and increase endothelial nitric oxide synthesis, in patients with acute myocardial infarction. Methods This study included 41 patients with insufficient CCC and 43 patients with well-developed CCC who were hospitalized for acute myocardial infarction and underwent coronary angiography. The Cohen-Rentrop classification was used to grade the CCC. The patients were divided into two groups according to Rentrop grades: those with a 0-1 stage were considered as insufficient and those with grades of 2-3 were considered as well-developed CCC. We took blood samples to measure the adropin levels within the first 24 hours of hospitalization. Results The mean age was 59.1±11.9 years and 62 (73.8%) were male. The right coronary artery was the most frequently target vessel (n: 51, 60.7%), and the majority of the patients presented with ST-segment elevation myocardial infarction (STEMI) (n:58, 69%). The median interval between the severe chest pain and the intervention was significantly higher in patients with well-developed CCC (p=0.042). The serum adropin levels in patients with insufficient CCC were significantly lower than in those with well-developed CCC (196.3 [131.5 - 837.0] pg/mL vs. 235.5 [171.9 - 1124.2] pg/mL, p<0.001). Logistic regression analysis revealed that the circumflex artery as the target vessel, NSTEMI (non-STEMI) as the type of myocardial infarction, and serum adropin level were the independent risk factors for the prediction of poor coronary collateral vessel formation (p<0.05). Conclusions In this study, we found that in patients with acute myocardial infarction, those with well-developed CCC had higher adropin levels.
