Tofacitinib for the Treatment of Nail Lesions and Palmoplantar Pustulosis in Synovitis, Acne, Pustulosis, Hyperostosis, and Osteitis Syndrome.

ABSTRACT:

Importance

Nail involvement is common in synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome, which has a strong association with quality of life in patients with SAPHO. Tofacitinib is an oral Janus kinase inhibitor that has been previously shown to be effective for nail psoriasis.

Objective

To assess the efficacy and safety of tofacitinib for the treatment of nail involvement in SAPHO syndrome.

Interventions

Participants received tofacitinib, 5 mg, twice daily, for 12 weeks.

Design, setting, and participants

This open-label, single-arm, prospective pilot study included 13 patients with SAPHO syndrome accompanied by nail lesions and active palmoplantar pustulosis who were recruited from Peking Union Medical College Hospital from September 2019 to December 2019. Follow-up was completed in March 2020. Analysis began March 2020.

Main outcomes and measures

The primary end point was the percentage of the change from baseline in Nail Psoriasis Severity Index scores at week 12. Secondary end points included the percentage of the change from baseline in Palmoplantar Psoriasis Area and Severity Index scores, change from baseline in Visual Analogue Scale scores in global osteoarticular pain, Dermatology Life Quality Index scores, and inflammatory markers. Adverse events were recorded throughout the study.

Results

Thirteen female Asian patients (means [SD] age, 39.7 [12.3] years) were included, all of whom completed the study. At week 12, significant improvements were observed in Nail Psoriasis Severity Index scores (median, -67% [interquartile range (IQR), -56% to -77%]; P < .001) and Palmoplantar Psoriasis Area and Severity Index scores (median, -71% [IQR, -58% to -78%]; P < .001). Significant improvement was also noted in Dermatology Life Quality Index scores (median, -12 [IQR, -8.5 to -15]; P < .001) at week 12. A significant decrease in Visual Analogue Scale scores in global osteoarticular pain was observed at week 8 (median, -4 [IQR, 0 to -5]; P = .02) but was not significant at week 12. Inflammatory marker levels were decreased, as indicated by erythrocyte sedimentation rate (median, -8 mm/h [IQR, -4 mm/h to -11 mm/h]; P < .001) and high-sensitivity C-reactive protein levels (median, -1.6 [IQR, -0.3 to -4.1]; P = .01). No severe adverse events were observed.

Conclusions and relevance

In this pilot study, tofacitinib yielded significant remission of nail lesions and palmoplantar psoriasis accompanied by an improvement in quality of life in patients with SAPHO syndrome. Additional follow-up studies to evaluate the long-term efficacy and safety of tofacitinib for nail involvement in SAPHO syndrome are warranted.

Project description:OBJECTIVE:To characterize the high-resolution computed tomography (HRCT) pulmonary abnormalities in patients with synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome. METHODS:Pulmonary HRCT images were reconstructed from whole-spine computed tomography (CT) images of 67 patients with SAPHO syndrome. HRCT images of 58 healthy controls were also obtained and reviewed. Patients with pneumonia and tuberculosis were excluded. Demographic and clinical data such as gender, age, onset age, disease duration, erythrocyte sedimentation rate (ESR), highly sensitive C-reactive protein (hs-CRP) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were collected from the SAPHO syndrome patients. Demographic characteristics, ESR and hs-CRP data from the healthy controls were also recorded. Student's t test, Mann-Whitney U test, chi-squared test and logistic regression were employed to compare the HRCT findings of the two groups of patients. RESULTS:The median age of the SAPHO syndrome patients was 47.0 years, interquartile range [38.0-53.0]; that of the healthy controls was 37.0[30.8-53.8]. From the detailed HRCT evaluations, abnormalities were identified in 45 patients. We found irregular linear opacities in 29 (43.3%) patients, opacities in 22 (32.8%), ground-glass opacity in 11 (16.4%), pleural thickening in 9 (13.4%), solitary nodules in 6 (9%), bronchiectasis in 3 (4.5%), pulmonary bulla in 2 (3%), multiple nodules in 1 (1.5%), and reticular patterns in 1 (1.5%). Compared to the healthy controls, the SAPHO syndrome patients had a significantly higher rate of opacities but a significantly lower percentage of nodules (especially multiple nodules), although the overall rates of abnormal HRCT findings were similar in the two groups. According to the multivariate logistic regression analysis, increased age and BASDAI < 4 were significant predictors of abnormal HRCT findings. CONCLUSION:Our study is the first to address HRCT pulmonary abnormalities in SAPHO syndrome patients. SAPHO syndrome patients have a significantly higher percentage of opacities and a significantly lower rate of pulmonary nodules than healthy controls. BASDAI and age are possible good predictors of abnormal HRCT pulmonary findings.

Project description:INTRODUCTION:Palmoplantar psoriasis (PP) and palmoplantar pustulosis (PPP) are diseases affecting the hands and/or feet that can cause marked physical discomfort and functional disability. The tumor necrosis factor-alpha antagonists adalimumab, etanercept, and infliximab, the interleukin (IL)-17A inhibitors ixekizumab and secukinumab, and the IL-23 or IL-12/IL-23 inhibitors guselkumab and ustekinumab have been well studied for the treatment of moderate to severe plaque psoriasis. Less is known about the efficacy and safety of these agents for the treatment of PP (hyperkeratotic and pustular forms) and PPP. The aim of this review was to investigate the efficacy of biologic therapy for the treatment of hyperkeratotic PP, pustular PP, and PPP. METHODS:A systematic search of the medical electronic databases (Medline, Embase, and Cochrane Library) was conducted to identify studies or case reports which both used biologic therapy for the treatment of hyperkeratotic PP, pustular PP, and PPP and reported treatment outcomes. RESULTS:The systematic search identified 579 published articles, of which 44 were included in the analysis. Seven of the articles involved randomized placebo-controlled trials, two were open label trials, and the remaining were cohort studies, case series, or case reports. In the randomized controlled trials on the treatment of hyperkeratotic PP, adalimumab, guselkumab, infliximab, ixekizumab, and secukinumab each demonstrated superiority to placebo at 16, 16, 14, 12, and 12 or 16 weeks, respectively (p < 0.05). For the treatment of pustular PP, ustekinumab 45 mg was not superior to placebo at 12 and 16 weeks, respectively (p > 0.05), although an open label study demonstrated that four of five patients on a therapeutic regimen of ustekinumab 90 mg achieved clinical clearance at 16 weeks. For the treatment of PPP, etanercept and ustekinumab 45 mg were not superior to placebo at 12 and 16 weeks, respectively (p > 0.05). A combined analysis of studies for hyperkeratotic PP demonstrated that 94.7%, 90.0%, 82.5%, 89.1%, and 86.7% of patients experienced an improvement of at least 50% upon treatment with adalimumab, guselkumab, ixekizumab, secukinumab, and ustekinumab, respectively. In a combined analysis of case reports examining PPP, infliximab showed the greatest efficacy at 100.0% clinical improvement of patients from case reports, followed by ustekinumab at 58.8% clinical improvement. Few serious adverse events were reported, but several were reported in patients treated with infliximab or secukinumab. CONCLUSION:Biologic therapy is effective and well-tolerated for the treatment of hyperkeratotic PP, but less data are available on the treatment of pustular PP or PPP. Adalimumab, guselkumab, ixekizumab, secukinumab, and ustekinumab all showed > 80% efficacy for the treatment of hyperkeratotic PP, while infliximab and ustekinumab showed moderate efficacy for the treatment of pustular PP, and infliximab was the most efficacious treatment for PPP.

Project description:ImportanceAlthough palmoplantar pustulosis (PPP) can significantly impact quality of life, the factors underlying disease severity have not been studied.ObjectiveTo examine the factors associated with PPP severity.Design, setting, and participantsAn observational, cross-sectional study of 2 cohorts was conducted. A UK data set including 203 patients was obtained through the Anakinra in Pustular Psoriasis, Response in a Controlled Trial (2016-2019) and its sister research study Pustular Psoriasis, Elucidating Underlying Mechanisms (2016-2020). A Northern European cohort including 193 patients was independently ascertained by the European Rare and Severe Psoriasis Expert Network (2014-2017). Patients had been recruited in secondary or tertiary dermatology referral centers. All patients were of European descent. The PPP diagnosis was established by dermatologists, based on clinical examination and/or published consensus criteria. The present study was conducted from October 1, 2014, to March 15, 2020.Main outcomes and measuresDemographic characteristics, comorbidities, smoking status, Palmoplantar Pustulosis Psoriasis Area Severity Index (PPPASI), measuring severity from 0 (no sign of disease) to 72 (very severe disease), or Physician Global Assessment (PGA), measuring severity as 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), and 4 (severe).ResultsAmong the 203 UK patients (43 men [21%], 160 women [79%]; median age at onset, 48 [interquartile range (IQR), 38-59] years), the PPPASI was inversely correlated with age of onset (r = -0.18, P = .01). Similarly, in the 159 Northern European patients who were eligible for inclusion in this analysis (25 men [16%], 134 women [84%]; median age at onset, 45 [IQR, 34-53.3] years), the median age at onset was lower in individuals with a moderate to severe PGA score (41 years [IQR, 30.5-52 years]) compared with those with a clear to mild PGA score (46.5 years [IQR, 35-55 years]) (P = .04). In the UK sample, the median PPPASI score was higher in women (9.6 [IQR, 3.0-16.2]) vs men (4.0 [IQR, 1.0-11.7]) (P = .01). Likewise, moderate to severe PPP was more prevalent among Northern European women (57 of 134 [43%]) compared with men (5 of 25 [20%]) (P = .03). In the UK cohort, the median PPPASI score was increased in current smokers (10.7 [IQR, 4.2-17.5]) compared with former smokers (7 [IQR, 2.0-14.4]) and nonsmokers (2.2 [IQR, 1-6]) (P = .003). Comparable differences were observed in the Northern European data set, as the prevalence of moderate to severe PPP was higher in former and current smokers (51 of 130 [39%]) compared with nonsmokers (6 of 24 [25%]) (P = .14).Conclusions and relevanceThe findings of this study suggest that PPP severity is associated with early-onset disease, female sex, and smoking status. Thus, smoking cessation intervention might be beneficial.
