Nail Psoriasis Severity Index Score Research Articles

Rapid response of nail psoriasis to secukinumab in patients with moderate to severe psoriasis after 12 weeks of treatment with a total of 24 weeks of follow-up.

Nail psoriasis, a subtype of psoriasis, can cause significant pain, disability, and reduced quality of life. Despite the established efficacy of anti-IL17 secukinumab in improving skin psoriasis, there is a lack of clinical trials focusing on nail psoriasis as primary endpoint. This study aims to investigate the efficacy of secukinumab in treating nail psoriasis in patients with moderate to severe psoriasis. We prospectively recruited patients newly diagnosed with moderate to severe psoriasis in single centre from January 2021 to January 2022 who were treated with secukinumab. A total of 16 patients consisting of 9 males and 7 females were included. Their mean age was 38.88 ± 10.29 years. They had an average initial Nail Psoriasis Severity Index (NAPSI) score of 45.06 ± 20.39 and an average NAPSI score at 12 weeks of 8.94 ± 13.50, showing a significant (p < 0.05) decrease of NAPSI score after 12 weeks of secukinumab treatment. After 24 weeks of treatment, NAPSI score was decreased to 5.12 ± 8.52. Secukinumab rapidly improved nail psoriasis after 12 weeks of treatment, with further enhancement at 24 weeks, suggesting its potential as a potent therapeutic option for nail psoriasis.

Evaluation of serum selenium level in patients with plaque-type psoriasis

Back ground Psoriasis may be accompanied by homeostatic imbalance of some trace elements such as selenium (Se) that may influence disease management. Se has antiproliferative and immune-modulating properties. There are limited data about the imbalance of Se level in psoriasis patients with equivocal findings. Objective Aim of the study was to evaluate serum Se level in plaque-type psoriasis patients with different severity and chronicity of disease. Patients and methods In this case–control study during 18 months, Se level was analyzed in serum samples of 54 psoriasis patients and 54 healthy volunteers. Se level was measured with atomic absorption method. The extent of psoriasis was investigated using the psoriasis area severity index and nail psoriasis severity index scores. Age, sex, duration of psoriasis, severity scores, and levels of Se were collected and analyzed by SPSS software. Results There was no significant difference in Se levels between two groups (P=0.323). Also median level of Se in patients with different duration time of psoriasis was not significantly different (P=0.157). But there was significant differences in the median level of Se in mild group compared with severe (P=0.035) and moderate group (P=0.018). There was a nonsignificant correlation between severity and duration of psoriasis with Se level. Conclusion Considering these nonsignificant difference, we think that Se imbalance is not probably an important factor in our psoriasis patients.

Nail psoriasis in China: A prospective multicentre study.

Data on nail psoriasis (PsO) in China are scarce. To provide nail PsO-related data regarding epidemiologic characteristics, manifestations, fungal infections, arthritic complaints and treatments that may facilitate improved patient management globally. From August 2021 to August 2022, patients with nail PsO were enrolled in a prospective multicentre observational study at 25 hospitals in China. We collected and analysed data concerning nail PsO demography, clinical signs, fungal detection, arthritic symptoms and treatment. A total of 817 patients with nail PsO were involved, with a mean body mass index of 24.13 ± 2.93. In addition, 71.41% of the patients were male. The Nail PsO Severity Index score was weakly positively correlated with body surface area. The percentage of nail involvement was 95.29% for fingernails and 57.18% for toenails, with pitting (67.11%) and subungual hyperkeratosis (60.40%) being the most prevalent manifestations, respectively. Toenails showed a significantly higher frequency of nailfold scales, subungual hyperkeratosis and nail plate crumbling and a lower frequency of splinter haemorrhages, pitting and erythema of the lunula. A total of 13.26% of the PsO patients had onychomycosis, and 77.08% were observed in the toenails. Articular symptoms were reported by 12.17% of the patients, with the peripheral type being predominant. Significant associations between articular symptoms and nailfold swelling, subungual hyperkeratosis, nailfold scales, onycholysis and longitudinal ridges were found. Only 2.30% (20 out of 871) of patients with nail PsO received treatment. The most frequently employed therapy for cutaneous PsO with nail involvement was biologic therapy (n = 366). PsO showed distinct manifestations in the toenails and fingernails. Additionally, toenail PsO combined with onychomycosis requires special attention. Articular symptoms in psoriatic patients are associated with specific nail changes. It is important to research and advocate for more potent treatments for nail PsO.

Dermoscopic Features of Psoriatic Nails and Their Correlation to Disease Severity.

Nail psoriasis is a challenging chronic condition affecting patients functionally and psychologically. Nail involvement is observed in 15-80% of psoriatic patients with occasional presence of isolated nail psoriasis. To evaluate dermoscopic features of nail psoriasis and correlate them clinically. The study included fifty subjects with nail psoriasis. Psoriasis skin and nail severity was evaluated using psoriasis area severity index (PASI) and nail psoriasis severity index (NAPSI). Dermoscopy of the nails (onychoscopy) was performed, and features were recorded and analyzed. The most common clinical and dermoscopic findings were pitting (86%) and onycholysis (82%). Among all dermoscopic features of nail psoriasis, only longitudinal striations and subungual hyperkeratosis were significantly higher in patients with moderate to severe psoriasis than in patients with mild psoriasis (P=0.028; P=0.042, respectively). PASI scores correlated positively but none significantly with NAPSI scores (r = 0.132, P=0.360), and similarly, no significant correlation was observed between the duration of psoriasis and the dermoscopic NAPSI (r = 0.022, P=0.879). Dermoscopy can serve as a useful tool for early diagnosis of psoriatic nail changes not always visible to the naked eye and is a non-invasive easy-to-use confirmatory tool for nail changes in psoriatic disease or in isolated nail involvement.

Evaluation of Nail Psoriasis: Delving into Some Useful Scores

Introduction: Several scoring systems have been established for nail psoriasis severity assessment. However, there is a lack of consensus on these tools. Objectives: To evaluate the nail changes in psoriasis patients and to correlate the severity of nail findings by Nail Psoriasis Severity Index (NAPSI) and modified NAPSI (m-NAPSI) scores. Material and Methods: Three hundred and seventy consecutive adult psoriatic patients were studied to describe the pattern of nail changes with its frequency and the findings were compared with data collected on age-and gender-matched 150 control subjects to determine which of the observed features are psoriasis disease-specific nail changes. The nail severity was assessed by NAPSI and m-NAPSI scores and correlated. Results: Nail signs included in NAPSI were more commonly seen in psoriatic patients as compared to healthy controls and it was statistically significant. Beau’s line was also found more in patients as compared to controls. None of the cases and controls had red spots in the lunula, and leukonychia was comparatively common in the controls. There was a strong and significant correlation found between NAPSI and m-NAPSI (r=0.916). Fingernails had a stronger correlation as compared to toenails between NAPSI and m-NAPSI (r=0.920 vs. r=0.877; p&lt;0.001). Conclusions: m-NAPSI may be considered to measure the degree of nail changes however leukonychia and a red spot in the lunula could be removed and Beau’s line could be added as further modification of m-NAPSI.

A Real-Life Study on the Use of Tildrakizumab in Psoriatic Patients.

Tildrakizumab is a humanized IgG1κ monoclonal antibody that selectively targets the p19 subunit of interleukin IL-23, thereby inhibiting the IL-23/IL-17 axis, which is primarily implicated in the immunopathogenesis of psoriasis. Tildrakizumab is approved for the treatment of moderate-to-severe plaque-type psoriasis in adults based on the evidence of two randomized and controlled phase-III clinical trials (reSURFACE 1 and reSURFACE 2). Here, we report our real-life experience treating 53 psoriatic patients (19 female and 34 male) who were administered tildrakizumab every 12 weeks and received follow-ups over 52 weeks. Descriptive and inferential statistical analyses were performed, in particular the Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI) and, if applicable, the Nail Psoriasis Severity Index (NAPSI) and Palmoplantar Psoriasis Physician Global Assessment (PPPGA). These were assessed at baseline and after different timepoints (weeks) during the follow-up period. We described and evaluated demographical and epidemiological characteristics in our cohort group, focusing on comorbidities. In this group, 35.9% of patients were female and 64.1% were male, with 47.1% being smokers and with a mean age of 51.2 years. A total of 37.7% of these patients was affected by scalp psoriasis; regarding comorbidities, hypertension was the most frequent (32.5%), followed by psoriatic arthritis (PsA) (18.60%) and diabetes (13.9%). At week 52, 93%, 90.2% and 77% of patients achieved a PASI reduction ≥75% (PASI 75), PASI 90 and PASI 100, respectively. In addition, NAPSI, PPPGA and DLQI scores were significantly reduced by week 52. In our cohort of complex psoriasis patients, disease remission began at the end of the fourth week of treatment and remained constant from week 16 to week 52.

A cross-sectional observational study of clinical, histopathological, and dermoscopic correlation in patients with nail psoriasis at a tertiary care hospital

Background: Among various nail disorders encountered in dermatology outpatient department, nail psoriasis is not uncommon. Around 80%–90% of patients with psoriasis present with nail involvement at some point in their life. In 1%–5% of patients, alterations compatible with nail psoriasis may also occur in the absence of cutaneous lesions. There is limited literature on nail psoriasis especially in Indian patients. Objective: The present study was undertaken to evaluate clinical, histopathological, and dermoscopic features in nail psoriasis and its impact on quality of life. Materials and Methods: All clinically suspected cases of nail psoriasis were included in the study. Clinical parameters and dermoscopic findings were observed and noted. Nail biopsy was performed to confirm the findings. Impact on quality of life was evaluated by correlating Nail Psoriasis Severity Index (NAPSI) score and nail psoriasis quality of life scale (NPQ10) score. Results: Of 50 patients with clinically suspected nail psoriasis, skin involvement was seen in 45 (90%), and 5 (10%) had only nail involvement. The mean NAPSI score was 34.34 in our study. The most common clinical nail finding was pitting (38 [76%]) followed by onycholysis (31 [62%]). The most common dermoscopic finding was pitting (39 [76%]) followed by onycholysis (32 [64%]). Histopathologically, the most common finding was parakeratosis (41 [82%]) followed by focal hypergranulosis (40 [80%]). The majority of the patients (21 [42%]) had NPQ10 (modified) score between 10 and 20, and moderate positive correlation between NAPSI score and NPQ10 scale score was observed. Limitations: Small sample size and no control group. Conclusion: Nail psoriasis does impact the quality of life of patients especially in females who feel embarrassed in social gatherings and workplace. Nail biopsy, though painful and difficult to perform, is the most efficient method to diagnose nail psoriasis.

Nail Psoriasis Quality Of Life Scale 10 (Npq10) As A Predictor Of Quality Of Life In Nail Psoriasis Patients

Nail psoriasis can affect the patient's quality of life, so to evaluate the quality of life in patients with skin diseases in general, the Dermatology Quality of Life Index (DLQI) can be used. The questionnaire was unable to distinguish the impact on quality of life caused by nail abnormalities or skin lesions, so a special scoring system was needed to evaluate the quality of life for nail psoriasis patients with the Nail Psoriasis Quality of Life Scale 10 (NPQ10). To find the relationship between the severity of nail posirais based on Nail Psoriasis Severity Index (NAPSI) score with DLQI and NPQ10. The total respondents were 20 people with a diagnosis of nail psoriasis who came to the Dermatovenereology Outpatient Clinic of Dr. Moewardi General Hospital, Surakarta from April-June 2020. We took photography and dermoscopy of fingernails and toes and then calculated the NAPSI score. All respondents filled out the DLQI and NPQ10 questionnaires. Pearson's (r) correlation test was used to find the relationship between the mean and standard deviations of NAPSI and DLQI and NPQ10. We also tested the correlation between DLQI and NPQ10. The data significance value was declared significant if p &lt;0.05. The results of the correlation test between NAPSI scores with DLQI and NPQ10 showed a statistical relationship, where the correlation value between NAPSI and DLQI was slightly more significant than NPQ10 (r = 0.948: r = 0.877; p &lt;0.05). The mean value of DLQI and NPQ10 in women was higher than men (14.12 ± 8.21: 11.5 ± 8.29 and 11.5 ± 3.58: 8.16 ± 4.52) with a correlation test value of DLQI and NPQ10 is r = 0.888, p &lt;0.05. We found that the association between NAPSI correlates more significantly with DLQI than NPQ10. This may be due to some questions that do not reflect the daily activities of our study subjects, but NPQ10 score in women is higher than men where the quality of life for nail psoriasis is also influenced by gender.

102 A deep learning system enables a prompt and objective scoring of Nail Psoriasis Severity Index

In the practice of psoriasis, nail lesions must be accurately evaluated in addition to skin and joint lesions. Scoring with Nail Psoriasis Severity Index (NAPSI) is often used as a tool to assess the severity of nail psoriasis, but there are several vexing issues. First, calculating NAPSI scores on multiple digits is rather time-consuming. Second, NAPSI scores often vary widely among scoring dermatologists. In this study, we developed a deep learning-based NAPSI prediction system to solve the current problems of NAPSI scoring and make it easier and more effective to implement in daily clinical practice.

Ultrasound Can Be Usefully Integrated with the Clinical Assessment of Nail and Enthesis Involvement in Psoriasis and Psoriatic Arthritis.

Objectives: This study aimed to examine and compare the findings of nail and enthesis ultrasonography in patients with psoriasis and psoriatic arthritis. Methods: We identified 154 patients with psoriatic arthritis and 35 patients with psoriasis who were treated at Chang Gung Memorial Hospital, Taiwan, between September 2018 and January 2019. Results: There were significant differences in the Nail Psoriasis Severity Index scores and Glasgow Ultrasound Enthesitis Scoring System scores between patients with psoriasis and those with psoriatic arthritis. B-mode ultrasonography revealed that onychopathic changes were more common in the psoriasis group. The psoriatic arthritis group showed a higher proportion of lower-limb enthesopathy, with significant differences in distal patellar ligament thickness and Achilles tendon thickness. Conclusion: The findings of nail ultrasonography were more severe in psoriasis cases, and the ultrasonographic findings of enthesopathy of the lower limb were more severe in cases of psoriatic arthritis.

Sustained Resolution of Nail Psoriasis Through 5 Years with Ixekizumab: A Post-Hoc analysis from UNCOVER-3.

Nail psoriasis is a chronic, difficult-to-treat condition affecting almost half of patients with psoriasis. It is associated with considerable social stigma and impairment of patients' quality of life. The aim of this study was to assess improvements in objective measures of nail psoriasis among patients from the long-term extension of the UNCOVER-3 study who received the interleukin-17A inhibitor ixekizumab and had either any degree of nail psoriasis (Nail Psoriasis Severity Index (NAPSI) >=1) or significant nail psoriasis (fingernail NAPSI ≥ 16 and ≥ 4 fingernails involved) at baseline. Efficacy outcomes reported through week 264 included the mean percentage improvements from baseline in NAPSI score and the proportion of patients achieving nail psoriasis resolution (NAPSI=0). In UNCOVER-3, 56.9% (219/385) of patients had nail psoriasis at baseline; of those, 61.2% (134/219) had significant nail psoriasis. At week 60, a total of 66.9% and 59.1% of patients with baseline nail psoriasis and significant baseline nail psoriasis, respectively, reported complete clearance of nail psoriasis, an effect which was sustained through week 264. This analysis demonstrates that continuous treatment with ixekizumab in adult patients with moderate-to-severe-psoriasis through 264 weeks was associated with improvements and clearance of fingernail psoriasis, irrespective of the severity of nail psoriasis at baseline.

Factors affecting onychomycosis in patients with psoriasis.

Prevalence of onychomycosis increases in patients with psoriasis and that psoriasis predisposes to onychomycosis. It was aimed to determine the frequency of onychomycosis and responsible pathogens in patients with psoriasis, to reveal their differences compared to the population without psoriasis, and to determine the factors in this study. The study included 81 patients with nail disorder diagnosed with psoriasis. Clinical findings, psoriasis area and severity index (PASI), nail psoriasis severity index (NAPSI) scores, body mass indexes (BMI) and laboratory characteristics were recorded. Mycological examination by direct microscopy and fungal culture was performed both on nails that were considered onychomycosis and on nails with any of the psoriatic nail findings. The prevalence of onychomycosis was 27.2% in psoriasis patients. Nail involvement of psoriasis was found in 31.3% of the patients using biologic agents, 5.9% of those receiving conventional treatment, and 31.3% of those receiving topical treatment and 68.8% of the patients who did not receive treatment at all. The difference between the patients who did not receive treatment and those who received conventional treatment was significant (p < 0.05). There was growth in the fungal culture in 23.5% of the patients with psoriasis. There was no statistically significant relationship between onychomycosis and PASI, NAPSI score, and BMI (p > 0.05). Since the prevalence of onychomycosis in psoriasis patients receiving conventional and anti-TNF-α therapy is higher than in patients not receiving treatment, nail changes in these patients should be evaluated in more detail for the presence of onychomycosis. In addition, since more than one fungal agent can grow and non-dermatophyte molds are seen more frequently in patients with psoriasis, it should be taken into account that native and fungal culture examinations should be performed together.

Study of Nail Psoriasis and Dermoscopic Correlation with Dermoscopic and Modified Dermoscopic Nail Psoriasis Severity Indexes (dNAPSI and dmNAPSI).

BackgroundNail involvement in psoriasis may be assessed clinically, ultrasonologically, and dermoscopically. The aim of this study was to assess the dermoscopic features of nails in psoriasis, to compare them with the clinical findings, and to correlate them with the Nail Psoriasis Severity Index (NAPSI) score.MethodsWe recruited 120 patients with psoriatic nail changes for the study. The Psoriasis Area Severity Index (PASI) was used to assess the severity of disease. Clinical and dermoscopic (Derm-Lite DL4, ×10, polarized and non-polarized) nail examination determined NAPSI, modified NAPSI (mNAPSI), and NAPSI determined with dermoscopic findings (dermoscopic NAPSI [dNAPSI] and dermoscopic modified NAPSI [dmNAPSI]) were used to assess severity of nail involvement.ResultsSubungual hyperkeratosis (50.8%) and nail plate thickening (56.7%) were the commonest clinical nail changes found, and dermoscopically, they were subungual hyperkeratosis and pitting (68.3% each). The average median with interquartile range of PASI and NAPSI scores were 7.5 [5.7–10.8] and 8.0 [6–12], respectively. NAPSI scores increased significantly with the increase in PASI scores (P < 0.001). A comparison of NAPSI and mNAPSI with dNAPSI and dmNAPSI revealed that NAPSI, mNAPSI, and dNAPSI increased significantly with an increase in PASI scores. The dNAPSI scores increased significantly with increased mNAPSI and dmNAPSI, and mNAPSI and dmNAPSI were significantly good predictors of joint involvement in psoriasis.ConclusionsDermoscopy allows for better visualization of nail findings. Evaluating NAPSI and mNAPSI scores in conjunction with dNAPSI and dmNAPSI increases their helps detect early psoriasis, detection of worsening moderate-to-severe psoriasis (PASI >10) and predict joint involvement and their severity.

Novel transdermal device for delivery of triamcinolone for nail psoriasis treatment

Nail psoriasis treatment is challenging due to difficult drug delivery and systemic therapy toxicities. Self-dissolvable microneedle patches embedded with corticosteroids offers a potentially rapid, minimally invasive drug delivery platform with good efficacy and minimal adverse side effects. We conducted a 4-month prospective randomised controlled trial. Subjects with psoriatic nails were randomised to receive microneedle device delivered topical steroids on one hand and control treatment (topical Daivobet gel) on the other. Two independent dermatologists blinded to the treatment assignment scored their Nail Psoriasis Severity Index (NAPSI) during visits at baseline, 2 and 4 months. All treatment was discontinued after 2 months. Average NAPSI score on each hand was analysed. A total of 25 participants were recruited, aged 22 to 73 years. Majority were Chinese (72%), followed by Indian and Malay. There was equal randomisation of treatment to the left and right nail. While there was a rapid significant improvement in average NAPSI score for the control arm at 2 months, the treatment arm had a greater, more sustained improvement of the NAPSI score at 4 months. The average NAPSI score improved for both treatment and control group at 4 months compared to baseline. However, only the NAPSI value improvement in the controls at 2 months compared to baseline was statistically significant (P=0.0039). No severe adverse effects were reported. To the best of our knowledge, this is the first prospective randomised control trial comparing microneedle technology against conventional topical steroids in nail psoriasis treatment. Our findings demonstrate microneedle technology is as efficacious as topical therapy.

Ultrasound in Evaluation of Subclinical Enthesitis of Extensor Digitorum Tendon and Nail Unit Changes in Psoriasis

Abstract Background Subclinical inflammation at entheseal level has been detected in patients with psoriasis without previous history of arthropathy or Psoriatic arthritis (PsA). Ultrasound (US) is a valid and sensitive tool for the assessment of inflammatory involvement at entheseal level in PsA patients. Objective To detect subclinical arthritis or enthesitis at distal interphalangeal (DIP) fingers and nail unit changes in psoriatic patient for early detection of PsA Patients and Methods This study included 30 adult psoriatic patients and 30 healthy matched controls. All underwent history, clinical examination, Psoriasis Area and Severity Index (PASI), Nail Psoriasis Severity Index (NAPSI) score calculation and musculoskeletal US both grey and power Doppler (PD) assessed at enthesis of extensor digitorum tendon insertion at distal phalanx, DIP joints from 2nd to 5th finger bilaterally examined for detection of synovitis and over the nail for morpho-structural evaluation. Results Patient’s ages ranged from 18-65 years and controls 20-60 years (mean ±SD 45.07 ± 13.52, 38.37 ± 11.96 respectively), male to female ratio 1:2. DIP joint affection in the form of synovial hypertrophy and effusion with PD was found in 13.3% of cases. Enthesophyte with PD in 56.7% of cases. On comparison between NAPSI score by clinical examination versus US examination, the sensitivity of US was 100%, all cases clinically positive by NAPSI were positively affected by US (20 cases). Also 30% of cases were negative by NAPSI and were positive by US (7cases). Three cases were negative by both NAPSI and US. A significant positive correlation was observed between disease duration and NAPSI Score (r = 0.429, pvalue&amp;lt;0.05), similarly between presence of enthesophyte with PD and PASI Score (r = 0.547, pvalue&amp;lt;0.02). Conclusion Detection of subclinical enthesopathy at DIP joint by ultrasound is not infrequent, so it is an important tool for examining enthesis in psoriatic patients. The presence of a high PASI score and long disease duration could be considered as predictive parameters for the presence of psoriatic enthesitis ongoing to arthritis.

Comparison between the Efficacy of Intense Pulsed Light (IPL) versus Photodynamic Therapy with Methylene Blue in the Treatment of Nail Psoriasis

Abstract Background Nail psoriasis is often refractory to traditional treatments, and patients with nail psoriasis usually demand a therapeutic option. Both photodynamic therapy (PDT) and intense pulsed light have been evaluated in nail psoriasis. Objective The objective of this study was to evaluate and compare the efficacy of IPL and methylene blue assisted photodynamic therapy in the treatment of nail psoriasis. Patients and Methods Twenty patients (15 males and 5 females) with mild to moderate psoriasis with nail affection were included in this study. Their age ranged from 24 to 71 years. The PDT used IPL as the light source and methylene blue as photosensitizer. Sessions were applied every 2 weeks for a maximum of 3 months, treating one hand with IPL and the other with PDT. The nails treated were evaluated at baseline, after 2 sessions, after 6 sessions and 3 months after the last treatment session according to the Nail Psoriasis Severity Index (NAPSI) score. Follow-up was performed after 2 sessions, after 6 sessions, and 3 months after the last treatment session. Results A decrease in NAPSI score was observed with both treatments and in both nail bed and nail matrix involvement. No statistically significant difference was found between PDT and IPL as regarding total NPASI score. However, total NAPSI score improved by 61% in MB-PDT group versus 47% in IPL group. Patient follow-up revealed the appearance of new lesions in 3 patients in the group of IPL, and in 1 patient in the MB-PDT after 6 months. Conclusion Intense pulsed light and methylene blue assisted PDT are a promising effective modalities of treatment of nail psoriasis, which are easy to use, safe, and nearly pain-free. This was confirmed by the improvement NAPSI score.

The relationship between the nail and systemic enthesitis in psoriatic arthritis.

ObjectivePsoriatic nail disease is more common in PsA than in isolated skin psoriasis (PsO). The nail is closely integrated to the DIP joint entheses. US data have shown that those patients with nail disease in PsO are more likely to have systemic enthesitis. We examined whether there was a relationship between nail disease, DIP enthesitis and systemic enthesitis in established PsA.MethodsForty-six PsA participants with nail disease underwent US scanning of the nail unit and the DIP entheses along with peripheral entheseal sites according to the Madrid sonographic enthesitis index (MASEI).ResultsAt the finger level, there was a mild to moderate correlation between nail US changes and both clinical nail disease and DIP enthesis changes (DIP US) [Spearman correlation (rS) = 0.30, P < 0.001 and rS = 0.16, P < 0.001, respectively]. At the patient level, there was a moderate correlation between the nail US score and nail psoriasis severity index score and DIP US (rS = 0.33, P = 0.024 and rS = 0.43, P = 0.003, respectively). At the patient level, there was also a positive correlation between a higher nail US score and the active peripheral enthesitis score (MASEI-active) (rS = 0.35, P = 0.018). When power Doppler was part of nail US score, similar results were demonstrated at both the finger and patient levels.ConclusionThis study has demonstrated the utility of nail US imaging and the close relationship, on scanning, between the DIP entheses and the nail unit. In PsA, we have seen a correlation between active US changes at the nail and peripheral enthesitis, which requires further analysis.Trial registrationClinicalTrials.gov, https://clinicaltrials.gov, NCT03955861.

Apremilast improves quality of life and ultrasonography parameters in patients with nail psoriasis: A prospective cohort study

Specific studies on apremilast for nail psoriasis are lacking. Our objective was to evaluate the nail-specific patient-reported outcomes, clinical efficacy, ultrasound (US) parameters, and safety of apremilast for nail psoriasis. We conducted a prospective cohort study including adult patients with plaque and nail psoriasis with a fingernail Nail Psoriasis Severity Index (NAPSI) score of 12 or more. Patients were treated with apremilast 30mg b.i.d. for 52weeks. Forty-five patients were included. At week 52, the Nail Assessment in Psoriasis and Psoriatic Arthritis (NAPPA) Patient Benefit Index global weighted score was 2 or more in 52% of patients and NAPPA Quality of Life and fingernail NAPSI improved by 57% and 53%, respectively. US parameters improved from week 16 onwards. Target nail NAPSI improvements were higher for nail matrix scores (60%) than for nail bed scores (38%, p<0.001). Baseline target nail bed NAPSI was associated with not achieving a target nail 50% reduction in NAPSI score at week 52 in the bivariate analysis (p=0.024). Safety was consistent with the known apremilast profile. Results from apremilast therapy for 52weeks in patients with psoriasis and predominant nail disease show significant improvements in nail-specific quality of life, clinical signs, and structural restoration on US, suggesting that apremilast may be considered in the treatment of nail psoriasis.

Effectiveness and safety of apremilast in biologic-naïve patients with moderate psoriasis treated in routine clinical practice in Greece: the APRAISAL study.

Apremilast is an oral phosphodiesterase-4 inhibitor indicated for patients with moderate-to-severe chronic plaque psoriasis and active psoriatic arthritis. To examine the effectiveness of apremilast on Dermatology Life Quality Index (DLQI), Psoriasis Area and Severity Index (PASI) and nail, scalp and palmoplantar involvement, when administered prior to biologics. This 52-week real-world study included biologic-naive adults with moderate psoriasis (psoriasis-involved body surface area 10% to <20%, or PASI 10 to <20 and DLQI 10 to <20). Apremilast was initiated ≤7days before enrolment. Data from the first 100 eligible patients who completed 24weeks (W24) of observation (or were prematurely withdrawn) are presented in this interim analysis using the last-observation-carried-forward imputation method. Eligible patients (mean age: 49.9years; 71.0% males; median disease duration: 8.0years) were consecutively enrolled between April and October 2017, by 18 dermatology specialists practising in hospital outpatient settings in Greece. Baseline DLQI (median: 12.0) and PASI (median: 11.7) scores improved (P<0.001) at all postbaseline timepoints (Weeks 6, 16 and 24; W24 median decreases: 9.0 and 9.4 points respectively). At W24, DLQI ≤5, DLQI 0 or 1, and PASI-75 response rates were 63.0%, 25.0% and 48.0% respectively. The Nail Psoriasis Severity Index score in patients with baseline nail involvement (n=57) decreased at all postbaseline timepoints (P<0.001; W24 median decrease: 20.0 points). At W24, 50.0% and 51.7% of patients with baseline scalp (n=76) and palmoplantar (n=29) involvement respectively achieved postbaseline Physician's Global Assessment (PGA) score of 0 or 1 if baseline score was ≥3, or 0 if baseline score was 1 or 2. The adverse drug reaction rate was 21.0% (serious: 2.0%). These interim results indicate that through 24weeks, apremilast improved quality of life and reduced disease severity in biologic-naive patients with moderate plaque psoriasis, while demonstrating safety consistent with the known safety profile.

Correlation between nail psoriasis severity index score with quality of life in nail psoriasis

Background: Psoriasis is a recurring chronic inflammatory disease, which can involve the skin, nails and joints. Nail psoriasis occurred in 50% of psoriasis patients. Nail psoriasis can interfere with the quality of life (QoL) due to its physical, mental, and social impacts. To determine the correlation between Nail Psoriasis Severity Index (NAPSI) score and QoL in nail psoriasis patients.Methods: This was a correlative analytical study with a cross-sectional approach that involved nail psoriasis subjects aged ≥18 years. Data accessed from the recording of basic data. The examination of subjects included an assessment of NAPSI scores and the Nail Psoriasis Quality of Life (NPQ10) questionnaire.
