Development and Validation of the Morphea Activity Measure in Patients With Pediatric Morphea

Morphea is an insidious inflammatory disorder of the skin and deeper tissues. Determining disease activity is challenging yet important to medical decision-making and patient outcomes. To develop and validate a scoring tool, the Morphea Activity Measure (MAM), to evaluate morphea disease activity of any type or severity that is easy to use in clinical and research settings. This pilot diagnostic study was conducted from September 9, 2019, to March 6, 2020, in 2 phases: development and validation. During the development phase, 14 morphea experts (dermatologists and pediatric dermatologists) used a Delphi consensus method to determine items that would be included in the MAM. The validation phase included 8 investigators who evaluated the tool in collaboration with 14 patients with pediatric morphea (recruited from a referral center [Medical College of Wisconsin]) during a 1-day in-person meeting on March 6, 2020. During the development phase, online survey items were evaluated by experts in morphea using a Likert scale (score range, 0-10, with 0 indicating not important and 10 indicating very important); agreement was defined as a median score of 7.0 or higher, disagreement as a median score of 3.9 or lower, and no consensus as a median score of 4.0 to 6.9. During the validation phase, reliability (interrater and intrarater agreement using intraclass correlation coefficients), validity (using the content validity index and κ statistics as well as correlations with the modified Localized Scleroderma Severity Index and the Physician Global Assessment of Activity using Spearman ρ coefficients), and viability (using qualitative interviews of investigators who used the MAM tool) were evaluated. Descriptive statistics were used for quantitative variables. Data on race and ethnicity categories were collected but not analyzed because skin color was more relevant for the purposes of this study. Among 14 survey respondents during the development phase, 9 (64.3%) were pediatric dermatologists and 5 (35.7%) were dermatologists. After 2 rounds, a final tool was developed comprising 10 items that experts agreed were indicative of morphea activity (new lesion in the past 3 months, enlarging lesion in the past 3 months, linear lesion developing progressive atrophy in the past 3 months, erythema, violaceous rim or color, warmth to the touch, induration, white-yellow or waxy appearance, shiny white wrinkling, and body surface area). The validation phase was conducted with 14 patients (median age, 14.5 years [range, 8.0-18.0 years]; 8 [57.1%] female), 2 dermatologists, and 6 pediatric dermatologists. Interrater and intrarater agreement for MAM total scores was good, with intraclass correlation coefficients of 0.844 (95% CI, 0.681-0.942) for interrater agreement and 0.856 (95% CI, 0.791-0.901) for intrarater agreement. Correlations between the MAM and the modified Localized Scleroderma Severity Index (Spearman ρ = 0.747; P < .001) and the MAM and the Physician Global Assessment of Activity (Spearman ρ = 0.729; P < .001) were moderately strong. In qualitative interviews, evaluators agreed that the tool was easy to use, measured morphea disease activity at a single time point, and should be responsive to changes in morphea disease activity over multiple time points. In this study, the MAM was found to be a reliable, valid, and viable tool to measure pediatric morphea activity. Further testing to assess validity in adults and responsiveness to change is needed.

Effect of pregnancy on scleroderma progression.

To explore the trajectory of scleroderma disease activity in women who experienced a pregnancy after systemic sclerosis diagnosis compared to nulliparous women. We analyzed data from the Canadian Scleroderma Research Group registry by identifying nulliparous women and women with ⩾1 pregnancy after systemic sclerosis diagnosis. Patient characteristics were compared between groups at registry entry. Controlling for age, smoking, and time since systemic sclerosis diagnosis, generalized estimating equations tested the effect of pregnancy on force vital capacity, diffusing capacity of the lungs for carbon monoxide, right ventricular systolic pressure, glomerular filtration rate, antibody status, active digital ulcers, physician global assessment of activity, and severity over 9 years. At registry entry, numbers of women in the nulliparous and pregnancy after systemic sclerosis diagnosis groups were 153 and 45, respectively. Corresponding numbers at 6 and 9 years were 48 and 21, and 18 and 9, respectively. The prevalence of anti-topoisomerase positivity was 18.3% in nulliparous and 12.5% in pregnancy after systemic sclerosis diagnosis. Baseline differences included mean (Standard deviation) age of diagnosis (nulliparous: 38.8 (14.0), pregnancy after systemic sclerosis diagnosis: 22.6 (6.8) years, p < 0.001), disease duration (nulliparous: 9.6 (8.9), pregnancy after systemic sclerosis diagnosis: 21.9 (9.6) years; p < 0.001), and inflammatory arthritis (nulliparous: 41 (28%), pregnancy after systemic sclerosis diagnosis: 22 (49%), p = 0.009). There were no significant differences between groups in the change of any outcomes over time. Results demonstrated that having ⩾1 pregnancy after systemic sclerosis diagnosis did not appear to significantly impact long-term renal, respiratory, or global function outcomes. While this offers a hopeful message to systemic sclerosis patients planning a pregnancy, physicians and patients should remain vigilant for potential post-partum complications.

Preliminary evidence on abatacept safety and efficacy in refractory juvenile localized scleroderma.

To evaluate the safety and efficacy of abatacept treatment for refractory juvenile localized scleroderma (jLS) in a retrospective study. A multicentre cohort study was performed to evaluate jLS subjects treated with abatacept with follow-up for 12 months to maximum of 24 months. Assessments at 6-month intervals included skin activity measures and physician global assessment of activity (PGA-A). Descriptive statistical analysis was performed. Eighteen subjects were studied with median age of 13.4 years, the majority had linear scleroderma subtype, and musculoskeletal involvement. All had previously failed MTX and/or mycophenolate mofetil treatment and glucocorticoids. Abatacept was added to the subject's maintenance DMARD treatment; 13 also received glucocorticoids at start of abatacept. No serious adverse events occurred. Skin activity and PGA-A scores declined in nearly all by 6 months and continued to improve from 6 to 12 months. At 12 months, 15 (83%) subjects were considered responders, two (11%) treatment failures, and one dropped out for adverse event. Response was sustained for 11 (61%) subjects to 18 months and eight (44%) to 24 months. Overall, four (22%) subjects were treatment failures and three (16.7%) discontinued abatacept for adverse event. Active musculoskeletal problems improved in most affected subjects. Ten subjects were able to discontinue initial glucocorticoid and six concomitant DMARD treatment. Abatacept was found to be safe and effective for jLS subjects refractory to standard of care treatment. Subjects experienced improvement in both skin and musculoskeletal activity. Prospective studies should be performed to more fully evaluate abatacept's efficacy.

Using the Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) to classify morphoea by severity and identify clinically significant change.

Validated scoring measures in morphoea can facilitate clinical trials. To ascertain the clinical significance of scores on the Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) and identify the change in scores correlated with clinically meaningful change. A prospective study of 120 participants from the Morphea in Adults and Children (MAC) cohort was undertaken. Physician's subjective assessments of severity and of improvement were completed at each visit. Receiver operating characteristic analysis determined LoSCAT scores corresponding with mild, moderate and severe disease, and absolute and percentage changes in scores corresponding with improved or worsened disease activity or damage. Mild, moderate and severe activity corresponded with LoSCAT activity index (LoSAI) scores of 0-4, 5-12 and 13 and over, and with Physician's Global Assessment of activity (PGA-A) scores of 0-10, 11-30 and 31 and over. Mild, moderate and severe damage corresponded with LoSCAT damage index (LoSDI) scores of 0-10, 11-15 and 16 and over, and with PGA of damage (PGA-D) scores of 0-18, 19-30 and 31 and over. Improved activity was best indicated by LoSAI decrease of at least 2 points or 27·5%, or PGA-A decrease of at least 6 points. Improved damage was best indicated by LoSDI score decrease of at least 2 points. Worsening activity was best indicated by LoSAI increase of at least 2 points or 19·5%, or PGA-A increase of at least 4 points. Worsening damage was best indicated by LoSDI increase of at least 25·5%. The LoSCAT can be used to classify patients with morphoea by disease severity, and identify clinically significant improvement in activity. What's already known about this topic? The Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) is a clinical tool that separately quantifies disease activity and damage in morphoea, and prior studies have demonstrated validity and reliability. What does this study add? The LoSCAT can be used to classify patients with morphoea by disease severity into mild, moderate and severe groups, and to identify clinically significant improvement in disease activity in patients with morphoea. The LoSCAT may be limited in its ability to detect clinically significant changes in disease damage.

Association between quality of life and clinical characteristics in patients with morphea.

Morphea can lead to considerable cosmetic or functional impairment; nevertheless, health-related quality of life (HRQoL) is rarely documented in adult morphea patients. To investigate the impact of morphea on HRQoL and to identify determinants of impaired HRQoL. A cross-sectional study has been carried out among adult morphea patients. HRQoL was evaluated by the Dermatology Life Quality Index (DLQI). The modified Localised Scleroderma Skin Severity Index (mLoSSI) and the Localised Scleroderma Damage Index (LoSDI) were applied to evaluate disease activity and damage, respectively. Physician Global Assessment of Activity and Damage (PGA-A, PGA-D) were also completed. Determinants of HRQoL were analysed by multiple regression. A total of 101 patients (84% females) entered the study, with a mean age of 56.8 ± 14.8years. Median mLoSSI, LoSDI, PGA-A and PGA-D scores were 8, 5, 9 and 9 points, respectively. Patients with generalised localised (51%) and plaque-type morphea (45%) had median total DLQI scores of 4 and 1, respectively. Embarrassment (53%), itchy or painful skin (46%), and clothing issues (43%) were the most commonly reported problems in the DLQI. Female gender, generalised morphea, higher disease activity (PGA-A score) and involvement of hands and/or feet were significant predictors of impaired HRQoL (p < 0.05). This study represents the largest sample of adult morphea patients surveyed about their HRQoL in Europe. The frequent occurrence of embarrassment warrants an increased attention to improve patients' mental health. Care must be taken in case of involvement of functionally sensitive areas, as these cases might require more intensive treatment.

A pilot study of acupuncture as adjunctive treatment of rheumatoid arthritis

We evaluated the efficacy of acupuncture as a useful adjuvant treatment in the management of rheumatoid arthritis (RA). A pilot, randomized, double-blind, and controlled clinical trial was conducted. Forty RA patients with active disease despite stable therapy for at least the preceding 1 month were randomized to receive a standard protocol of acupuncture (AC) or superficial acupuncture at non-acupuncture points (controlAC) for 9 weeks. The primary outcome was achievement of 20% improvement according to the American College of Rheumatology (ACR) 20 criteria after five and ten treatment sessions and after 1 month of follow-up. Secondary measures included Disease Assessment Scale (DAS), tender and swollen joint count, morning stiffness, Health Assessment Questionnaire (HAQ), visual analogue scale (VAS) of pain, physician global assessment of activity disease, physician and patient global assessment of treatment, and inflammatory markers (erythrocyte sedimentation rate and C-reactive protein). There was not significant difference between the groups regarding the number of patients that reached ACR20 at the end of the treatment (p=0.479). However, after 1 month of follow-up, there was a trend in favor of the AC group, with p=0.068. Compared with the controlAC, the AC group also demonstrated significant improvement in the patient and physician global assessment of treatment and physician global assessment of disease activity, but there was no difference on other clinical and laboratorial measures. On the other hand, only the AC patients had within group improvement on the variables DAS, HAQ, morning stiffness, patient and physician global assessment of treatment, and physician global assessment of disease activity in comparison to baseline visit. Despite the improvement of some studied variables, there was no significant difference in the proportion of patients that reached ACR20 between the AC and controlAC groups. This negative result can be related to the small sample size, selection of patients, type of acupuncture protocol applied, and difficulties in establishing an innocuous and trustworthy placebo group to studies involving acupuncture.
