Atorvastatin as adjunctive therapy for chronic plaque type psoriasis versus betamethasone valerate alone: A randomized, double-blind, placebo-controlled trial.

BACKGROUND: Psoriasis is a T helper 1 cell-mediated chronic inflammation. Statins have been found to have anti-inflammatory and immunomodulatory effects targeting T helper 1 cells and thus, are being investigated as treatments for psoriasis. AIMS: To investigate the efficacy and safety of atorvastatin as adjunctive treatment for mild to moderate chronic plaque psoriasis; and the impact of atorvastatin on quality of life. The study also aimed to correlate the beneficial effects of atorvastatin with its lipid-lowering effects. METHODS: Twenty-eight (19-65 year old) mild-moderate chronic plaque psoriasis patients were randomly assigned to two groups (treatment group: atorvastatin 40 mg OD; control group: placebo OD) and followed up for 6 months. All were allowed to use betamethasone valerate 0.1% ointment twice a day for a maximum of 3 weeks continuous application with 1-week rest periods in between. Primary outcome measures were the mean percentage reduction in Psoriasis Area and Severity Index (PASI) scores and percentage of patients achieving PASI-50. RESULTS: Fourteen patients (treatment: 6, control: 8) completed the trial. Mean reductions in PASI scores between the treatment (2.15 ± 2.17) and control (1.69 ± 2.36) groups were not statistically significant (P = 0.636). Intention-to-treat analysis of PASI-50 showed increased risk of treatment failure with atorvastatin as adjunct but estimates were not significant. Changes in Dermatology Life Quality Index (DLQI) scores (P = 0.214) and high-sensitivity C-reactive protein (P = 0.884) were likewise not statistically significant. Reductions in PASI scores were not linearly correlated with reductions in total cholesterol (P = 0.924), triglycerides (P = 0.274), low-density lipoprotein-cholesterol (P = 0.636), high-density lipoprotein-cholesterol (P = 0.584), or high-sensitivity C-reactive protein levels (P = 0.906). Adverse effects in the treatment group were transient elevated transaminases (n = 1) and mild myalgia (n = 1). LIMITATIONS: A 50% dropout rate was experienced. This remarkably high dropout rate decreases the robustness of the study results. CONCLUSIONS: Although atorvastatin exhibited earlier percentage reduction in PASI scores, it was not able to produce an additional benefit compared to psoriatic patients applying steroid alone.

Cutaneous Drug Reactions in a tertiary government hospital in the Philippines 2009-2011

OBJECTIVES: To determine the frequency of cutaneous drug reactions (CDRs), thier associated drugs, and morphological presentation min the Philippine General Hospital (PGH) from 2009 to 2011 and to identify new or uncommon drugs causing CDRs. METHODS: This is a 3-year retrospective record review. The Naranjo algorithm was used to score drug causality. RESULTS: One hundred and forty-three (143) patient records were retrieved, with 218 associated drugs identified. The most common drug classes were antibiotics (29%), anti-tuberculosis medications (17%), and NSAIDs (9%). The most common drugs were isoniazid, rifampicin, pyrazinamide, ethambutol (HRZE) combination drug (9%); amoxicillin (6%); and cotrimoxazole (5%). A morbiliform reaction (49%) was the most common morphological presentation. There were several identified drugs, including anti-fungals and beta-blockers, which caused a single drug reaction but had a sufficient Naranjo score to warrant inclusion. CONCLUSION: The most common drug classes, drugs, and cutaneous morphological presentation found in this study are similar to those seen in existing literature. However, there were several drugs identified causing single drug reactions. This may reflect the need for improved documentation, diagnosis, and follow-up of CDR cases in the PGH.
