ABSTRACT

Background@#Oral acitretin (ACT) has been approved for the treatment of psoriasis (PSO), whereas alitretinoin (ALI) has been prescribed off-label. Few studies have compared the efficacy of these two therapeutics. @*Objective@#To evaluate the clinical outcomes of oral ACT versus ALI for treating PSO. @*Methods@#Sixty-five patients diagnosed with PSO and treated with ACT or ALI were reviewed. Patient demographics, clinical efficacy, and adverse effects were evaluated. Treatment efficacy was assessed using physician’s global assessment (PGA) and psoriasis area and severity index (PASI). @*Results@#A total of 38 cases in the ACT group and 27 cases in the ALI group in PSO were retrospectively reviewed. No significant intergroup differences were noted in the proportion of patients achieving PGA score of “clear” or “almost clear” (18.42% vs. 22.22%; p=0.71). The reduction rate of PASI from baseline was higher in the ALI group (24.30% vs. 22.74%; p=0.68), while the rate of achieving 75% improvement in PASI was higher in the ACT group (18.42% vs. 14.81%; p=0.75); no significantly differences were noted. The ALI group had fewer adverse effects (6/27 [22.22%]) than the ACT group (10/38 [26.32%]), and no severe events occurred in either group. @*Conclusion@#ALI can be considered an off-label treatment option for a limited patient population.

ABSTRACT

Pilomatricoma is a common benign tumor that originates from hair matrix cells. Bullous pilomatricoma (BP) is a rare variant that often occurs on the upper extremities. A 23-year-old male presented with a cyst on the left upper arm for 6 months. He received the BNT162b2 (Pfizer) mRNA COVID-19 vaccine in the same location approximately 6 months prior to presentation. The lesion appeared 1 week after inoculation and gradually enlarged.Physical examination revealed a 2.5-×2.0-cm-sized, pinkish cystic nodule on the left upper arm. The lesion was excised, and histopathological examination showed a well-circumscribed nodule composed of basophilic cells and eosinophilic shadow cells. Finally, the patient was diagnosed with BP. The exact cause of BP formation following vaccination is yet to be determined; however, this report presents the possibility of BP occurrence in individuals with chronic skin lesions at the site of vaccination.

ABSTRACT

UI026 is an expectorant and antitussive agent which is a new combination of Pelargonium sidoides extract andCoptis extract. The bioactive compounds of Pelargonium sidoides and Coptis extracts were identified as epicatechin and berberine, respectively. This study evaluated the effect of food on the pharmacokinetics (PKs) and safety of UI026. A randomized, openlabel, single-dose, 2-treatment, parallel study in 12 healthy male subjects was performed. Subjects received a single oral dose of UI026 (27 mL of syrup) under a fed or fasted condition according to their randomly assigned treatment. Blood samples for the PK analysis were obtained up to 24 hours post-dose for berberine and 12 hours post-dose for epicatechin. The PK parameters were calculated by non-compartmental analysis. In the fed condition, the mean maximum plasma concentration (C max ) and mean area under the plasma concentrationtime curve from time zero to the last observed time point (AUC last ) for berberine were approximately 33% and 67% lower, respectively, compared with the fasted condition, both showing statistically significant difference. For epicatechin, the mean C max and mean AUC last were about 29% and 45% lower, respectively, compared to the fasting condition, neither of which showed a statistically significant difference. There were no drug-related adverse events. This finding suggests that food affects the systemic exposure and bioavailability of berberine and epicatechin.

ABSTRACT

BACKGROUND: It is not well known about the implication of left ventricular (LV) strain as a predictor for mortality in patients with chronic aortic regurgitation (AR). The purpose of this study was to investigate whether global longitudinal strain measured by two-dimensional speckle-tracking echocardiography could predict long-term outcome in patients with chronic AR. METHODS: This is a single center non-randomized retrospective observational study. The patients with chronic AR from January 2002 to December 2012 were retrospectively enrolled. Following patients were excluded; combined other significant valvular disease, previous heart surgery, aortic disease, congenital heart disease, acute AR and young age under 18 years old. Finally, 60 patients were analyzed and the LV global strain rate was measured on apical four chamber image (GS-4CH). RESULTS: During 64 months follow-up duration, 16 patients (26.7%) were deceased and 38 patients (63.3%) underwent aortic valve replacement (AVR). Deceased group was older (69 years old vs. 51 years old, p < 0.001) and had lower longitudinal strain (-12.05 +/- 3.72% vs. -15.66 +/- 4.35%, p = 0.005). Kaplan-Meier survival curve stratified by GS-4CH showed a trend of different event rate (log rank p = 0.001). On multivariate analysis by cox proportional hazard model adjusting for age, sex, body surface area, history of atrial fibrillation, blood urea nitrogen, LV dilatation, LV ejection fraction and AVR, decreased GS-4CH proved to be an independent predictor of mortality in patients with chronic AR (hazard ratio 1.313, 95% confidence interval 1.010-1.706, p = 0.042). CONCLUSION: GS-4CH may be a useful predictor of mortality in patient with chronic AR.
