Comparative effectiveness of switching paroxetine formulation for treatment of major depressive disorder: an open-label multicenter study.

AIM: To assess the effectiveness and safety of switching the antidepressant formulation from immediate-release (IR) to controlled-release (CR) paroxetine in patients with major depressive disorder (MDD). PATIENTS AND METHODS: A total of 113 outpatients with MDD diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, and treated with a stable dose of IR paroxetine for at least 6 months were enrolled. Patients were then switched to CR paroxetine for 8 weeks. Effectiveness was evaluated by scores on the Himorogi Self-Rating Depression/Anxiety Scales (HSDS/HSAS) and the Clinical Global Impression - Severity (CGI-S). Safety was evaluated based on the reported adverse drug reactions (ADRs). Medication satisfaction and preference were assessed based on questionnaire responses using Likert-type scales. RESULTS: The overall patient HSDS/HSAS scores significantly improved after switching from IR to CR paroxetine (P<0.001). Furthermore, CR paroxetine was superior to IR paroxetine (P<0.001) according to the results of the CGI-S evaluation. ADRs were experienced by 14 (12.4%) patients, including dry mouth, nausea/vomiting, somnolence/drowsiness, and wakefulness/arousal during sleep. Satisfaction and preference for paroxetine improved after switching to the CR formulation (P<0.001; chi-square test). CONCLUSION: These results suggest that switching the treatment from IR to CR paroxetine could improve depressive symptoms and decrease ADRs. However, these results may have been caused by the psychological effect of drug switching. Hence, future studies with blinded evaluation methods are required to confirm and expand our findings.

Safety profile of tacrolimus in patients with rheumatoid arthritis.

We assessed the safety of tacrolimus therapy for rheumatoid arthritis. Forty-two patients who started tacrolimus therapy between April 2005 and July 2006 were investigated retrospectively using data from their medical records up to June 2007. The cumulative treatment continuation rate was assessed by the Kaplan-Meier method. Fisher's exact test was used to compare gastrointestinal symptoms between different tacrolimus doses and between the presence and absence of each concomitant medication. The mean (+/-SD) observation period was 288 +/- 238 days. The cumulative treatment continuation rate was, respectively, 59.5% and 38.1% at 6 months and 1 year after the patients started treatment. Tacrolimus was discontinued in 28 patients, and was discontinued because of adverse reactions in 21 patients. Gastrointestinal symptoms were the most common adverse reactions (45.2% = 19/42 patients), followed by infections and hyperglycemia. Tacrolimus was discontinued in 9/19 patients with gastrointestinal symptoms, and was discontinued within 60 days of starting treatment in seven of them. Nausea and vomiting led to discontinuation in seven patients (within 60 days of starting treatment in six of them). The incidence of gastrointestinal symptoms was higher in patients receiving a daily dose >or=2 mg than in those receiving <2 mg/day. During treatment of rheumatoid arthritis by oral tacrolimus therapy, gastrointestinal symptoms were common, early, and dose-dependent. However, these symptoms were not severe and did not cause any serious safety problems.

A case of systemic sclerosis complicated by idiopathic portal hypertension: case report and literature review.

We encountered a 62-year-old woman who had systemic sclerosis (SSc) complicated by idiopathic portal hypertension (IPH). She had a 10-year history of scleroderma and Raynaud's phenomenon. She also had pancytopenia, splenomegaly, and esophageal varices. Treatment with prednisolone and endoscopic variceal ligation resulted in improvement of her symptoms. According to our literature review, the prognosis of patients with SSc complicated by IPH is relatively poor. However, the factors that predict outcome of these patients have not been elucidated.
