PURPOSE: To evaluate the effect and improvement of potassium aminobenzoate (500 mg Peyron capsule) in oral therapy for Peyronie's disease. MATERIALS AND METHODS: From February 2011 to September 2011, 31 patients with Peyronie's disease received potassium aminobezoate (500 mg Peyron capsules) and were divided into two groups. Group 1 (N=10) received potassium aminobezoate (500 mg Peyron capsule) 3 g four times daily without previous treatment of Peyronie's disease, while group 2 (N=21) received the same drug with previous treatment of Peyronie's disease (10 mg Tamoxifen +300 mg L-carnitine two times daily). Outcomes were assessed by subjective symptom change, pain relief, resolutions of the plaque, and curvature. RESULTS: After 3 months, there were no significant improvements in clinical outcomes of either group and among all the patients, 23 stopped taking potassium aminobezoate (23/31, 74%). The reasons for ceasing the therapy were gastrointestinal trouble (8/23, 35%), too many doses to take (7/23, 30%), ineffectiveness (6/23, 26%), and high price (2/23, 9%). CONCLUSIONS: Athough the etiology of Peyronie's disease has not been elucidated, potassium aminobenzoate in therapy of Peyronie's disease has been used. The use of this medication has the limitations of gastrointestinal trouble, ineffectiveness, too many doses, and high price. Further evaluations of the effect and appropriate dosing of potassium aminobenzoate are needed.

Background/Aims: To date, studies on various noninvasive techniques have been suggested to evaluate the degree of liver fibrosis. We aimed to investigate the diagnostic performance of se-rum asialo α1-acid glycoprotein (AsAGP) in the diagnosis of liver cirrhosis compared with chronic hepatitis for clinically useful result. Methods: We conducted a case-control study of 96 patients with chronic liver disease. Chronic hepatitis was defined as the presence of chronic liver disease on ultrasonography, with a liver stiffness of less than 5.0 kPa as shown on magnetic resonance elastography (MRE). Liver cirrho-sis was defined as liver stiffness of more than 5.0 kPa on MRE. The serum AsAGP concentration was compared between the two groups. Results: Serum AsAGP levels were significantly higher in patients with cirrhosis than in those with chronic hepatitis (1.83 μg/mL vs 1.42 μg/mL, p<0.001). Additionally, when comparing pa-tients in each cirrhotic group (Child-Pugh grades A, B, and C) to those with chronic hepatitis, AsAGP levels were significantly higher in all the cirrhotic groups (p<0.05, p<0.01, p<0.001, respectively). The sensitivity and specificity of AsAGP for detecting cirrhosis were 79.2% and 64.6%, respectively, and the area under the curve value was 0.733. The best diagnostic cutoff to predict cirrhosis was 1.4 μg/mL. AsAGP and bilirubin were found to be independent risk factors for the prediction of cirrhosis in the logistic regression analysis. Conclusions Serum AsAGP showed an acceptable diagnostic performance in predicting liver cirrhosis.
