A comparison between BSA, PASI, PLASI and SAPASI as measures of disease severity and improvement by therapy in patients with psoriasis

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2008
Tilo Henseler PhD
Background, This study investigates four measures of disease severity in patients with psoriasis, both before and after therapy. Methods, Data records were analyzed from 33 patients with moderate-to-severe chronic plaque psoriasis who were treated with efalizumab, 1 mg/kg/week subcutaneously, for 12 weeks. Four measures of disease severity were used: body surface area (BSA), psoriasis area and severity index (PASI), psoriasis log-based area and severity index (PLASI) and self-administered PASI (SAPASI). Results, At the end of the 12-week therapy, the mean percent improvement shown by each measure varied considerably, ranging from 48.6% (PASI) to 70.6% (SAPASI). PASI and PLASI were the most comparable (67.3% and 66.5%). These differences were smaller when a dermatologist's opinion about the improvement was taken into account, for example "very good improvement" ranged from mean percent improvement of 63.8% (BSA) to 83.8% (PASI). The correlation between all measures revealed a high level of significance (P, 10,5). Conclusions, Comparing the slopes and intercepts of the regression lines revealed PLASI as the most reliable measure for the severity and therapeutic improvement in patients with moderate-to-severe chronic plaque psoriasis. PLASI proved to be a marginally more accurate than PASI, and much more accurate than SAPASI and BSA. The superiority of PLASI may be a result of the logarithmic scale of the affected skin surface.

Abstract Aims The purpose of this study was to determine whether a percutaneous needle electrode (PNE) technique or a surgical first stage lead placement (FSLP) better predicted whether a patient would progress to implantation of a pulse generator (IPG) in older urge incontinent women. Methods Thirty subjects ,55 years with refractory urge incontinence who had been selected to undergo a test stimulation procedure were randomized to either PNE or FSLP. Thirteen underwent PNE placement and seventeen underwent FSLP placement. If during the test stimulation period subjects had greater than 50% improvement in their incontinence parameters they qualified for permanent lead and/or IPG implantation of the Interstim® device. Results Twenty-one subjects (70%) responded to the test stimulation and underwent implantation, 15/17 (88%) in the FSLP group and 6/13 (46%) in the PNE group. Subjects who were randomized to the FSLP group were significantly more likely to proceed to implantation of the IPG (P,=,0.02) than those in the PNE group. There was no significant difference in demographics, pre-test stimulation incontinence parameters or post-stimulation visual analog pain scores between the randomized groups or between test stimulation responders and non-responders. When comparing FSLP and PNE responders, there was no significant difference in the percent improvement in 24-hr pad weight, daily pad usage, or daily incontinence. Conclusion FSLP better predicted progression to implantation of the IPG than a test stimulation with a PNE in an older urge incontinent cohort. Neurourol. Urodynam. © 2006 Wiley-Liss, Inc. [source]


Direct comparison of treatment responses, remission rates, and drug adherence in patients with rheumatoid arthritis treated with adalimumab, etanercept, or infliximab: Results from eight years of surveillance of clinical practice in the nationwide Danish DANBIO registry

Objective To compare tumor necrosis factor , inhibitors directly regarding the rates of treatment response, remission, and the drug survival rate in patients with rheumatoid arthritis (RA), and to identify clinical prognostic factors for response. Methods The nationwide DANBIO registry collects data on rheumatology patients receiving routine care. For the present study, we included patients from DANBIO who had RA (n = 2,326) in whom the first biologic treatment was initiated (29% received adalimumab, 22% received etanercept, and 49% received infliximab). Baseline predictors of treatment response were identified. The odds ratios (ORs) for clinical responses and remission and hazard ratios (HRs) for drug withdrawal were calculated, corrected for age, disease duration, the Disease Activity Score in 28 joints (DAS28), seropositivity, concomitant methotrexate and prednisolone, number of previous disease-modifying drugs, center, and functional status (Health Assessment Questionnaire score). Results Seventy percent improvement according to the American College of Rheumatology criteria (an ACR70 response) was achieved in 19% of patients after 6 months. Older age, concomitant prednisolone treatment, and low functional status at baseline were negative predictors. The ORs (95% confidence intervals [95% CIs]) for an ACR70 response were 2.05 (95% CI 1.52,2.76) for adalimumab versus infliximab, 1.78 (95% CI 1.28,2.50) for etanercept versus infliximab, and 1.15 (95% CI 0.82,1.60) for adalimumab versus etanercept. Similar predictors and ORs were observed for a good response according to the European League Against Rheumatism criteria, DAS28 remission, and Clinical Disease Activity Index remission. At 48 months, the HRs for drug withdrawal were 1.98 for infliximab versus etanercept (95% 1.63,2.40), 1.35 for infliximab versus adalimumab (95% CI 1.15,1.58), and 1.47 for adalimumab versus etanercept (95% CI 1.20,1.80). Conclusion Older age, low functional status, and concomitant prednisolone treatment were negative predictors of a clinical response and remission. Infliximab had the lowest rates of treatment response, disease remission, and drug adherence, adalimumab had the highest rates of treatment response and disease remission, and etanercept had the longest drug survival rates. These findings were consistent after correction for confounders and sensitivity analyses and across outcome measures and followup times. [source]


Unipolar versus bipolar radiofrequency treatment of rhytides and laxity using a mobile painless delivery method

Macrene Alexiades-Armenakas MD
Abstract Background Previous studies have shown that radiofrequency (RF) energy is a safe and effective treatment for rhytide-reduction. Objective This randomized, blinded, split-face study assesses the safety and efficacy of the unipolar versus bipolar handpieces on an RF device with a mobile delivery method for the treatment of rhytides and laxity using quantitative grading. Methods In this randomized, blinded, split-face design study, 10 subjects (aged 18,75 years) with a clinically observable excess of rhytides and laxity (minimum grade 2 out of 4) on the face received four treatments at 1-week intervals with random assignment of unipolar RF to one side and bipolar RF to the contralateral side. Each side received approximately four passes per treatment delivered in a mobile continuous manner. Results were evaluated by two blinded investigators of photographs employing a comprehensive 4-point grading scale at baseline, and 1- and 3-month follow-up visits after the final treatment. Results All subjects completed and responded to treatment. The blinded evaluations demonstrated the following mean percent improvements in grading scores of rhytides and laxity: for the unipolar side 6.0±4.6% and 4.6±4.8% versus the bipolar side 4.4±2.5 and 7.3±3.5%. The degree of improvement approached but did not achieve statistical significance for either handpiece, but demonstrated a trend toward improvement (P,=,0.5599 unipolar vs. 0.1108 bipolar). The treatment was painless (rated 0 out of 10 by all subjects) and side effects included minimal erythema which resolved within 1,3 hours. No crusting, dyspigmentation or scarring was observed. Conclusion This randomized, split-face study with blinded evaluations employing a quantitative grading scale demonstrated that minimal pass, mobile energy delivery serial treatments with either the unipolar or bipolar handpieces of a novel RF device appears to safe and painless. Each handpiece demonstrated minimal clinical efficacy which was not statistically significant, but with a trend toward improvement in rhytides and laxity of facial skin. Lesers Surg.
