ABSTRACT
BACKGROUND/OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Nail psoriasis (NP) is often considered disfiguring for patients with a relevant impact on quality of life (QoL). It is also difficult to treat for dermatologists who are often frustrated by the scarcity of effective therapeutic alternatives in this particular location. Topical therapies are often used as the first-line treatment for mild NP, but efficacy is the modest. Conventional disease-modifying antirheumatic drugs (cDMARDs) (e.g., cyclosporine, methotrexate, acitretin, and dimethyl fumarate) are generally avoided in NP without general cutaneous involvement. Biologics represent, to date, a concrete possibility for the management of these patients. The data from the clinical trials are encouraging, although there are still few data in real-life. Here, we report a study conducted at Siena University Hospital on 20 patients with NP on both hands and feet treated with anti-IL23 for 52 weeks. No differences were evaluated from baseline to week 4 of anti-IL-23 treatment. NAPSI greatly improved at week 24 with almost 60% of patients reaching NAPSI75 and 40% NAPSI50. At week 52, almost 75% of patients reached NAPSI90. No adverse effects were reported in the patients in the study. The clinical response observed in these patients suggests that treatments that target interleukin-23 may be an effective option for NP, especially when refractory to conventional therapies.

Nail involvement can place a significant burden on patients as a result of functional damage and psychosocial problems, leading to major repercussions on the quality of life. There is strong evidence that nail psoriasis can often be difficult to treat. We report a 69-year-old man with severe onychodystrophy, onycholysis, and pain in the hands; he had been previously treated with topical and systemic traditional therapies without satisfactory response. The patient showed multiple severe psoriatic crumbly nails (nail psoriasis severity index [NAPSI] score of 69) and started ustekinumab treatment at standard dosage of 45 mg fl.s.c. After 24 weeks, both nail matrix and nail bed disease showed marked improvement and the patient continued therapy with ustekinumab (NAPSI 0 at week 104). At week 136 (September 2015), the patient had been complaining of hands pain (visual analogue scale pain: 80) and ultrasonographic (US) evaluations found a synovial proliferation with effusion on metacarpophalangeal joints. The patient continued therapy with ustekinumab, adding methotrexate 10 mg fl.s.c/week. In November 2016, the patient showed a remission of symptoms; clinical and US evaluations did not find signs of synovitis. Methotrexate treatment was suspended and currently the patient reached more than 4 years of ustekinumab treatment without sign and symptoms of synovitis.

BACKGROUND: Previous clinical trials have not evaluated improvement in nail psoriasis as a primary end point. OBJECTIVE: This phase 3 trial evaluated the safety and efficacy of adalimumab in patients with moderate-to-severe fingernail psoriasis and moderate-to-severe plaque psoriasis. METHODS: Patients were randomized 1:1 to 40 mg adalimumab every other week or placebo. The primary efficacy end point was at least 75% improvement in total-fingernail modified Nail Psoriasis Severity Index (NAPSI75) response rate at week 26. Ranked secondary end point scores evaluated at week 26 were total-fingernail NAPSI and modified NAPSI, nail pain, Nail Psoriasis Physical Functioning Severity, Brigham Scalp Nail Inverse Palmo-Plantar Psoriasis Index, and Physician's Global Assessment (fingernail psoriasis). RESULTS: Of the 217 randomized patients (108 received placebo and 109 received adalimumab), 188 (86.6%) completed 26 weeks of treatment (period A) or escaped early to the open-label period. The study met the primary end point (response rate of 3.4% with placebo vs 46.6% with adalimumab [P < .001]) and all ranked secondary end points. The serious adverse event rates (placebo vs adalimumab) in period A were 4.6% versus 7.3%; the serious infections rates were 1.9% versus 3.7%. LIMITATIONS: Patients with less than 5% BSA involvement were not eligible for enrollment. CONCLUSIONS: After 26 weeks of adalimumab treatment, significant improvements were seen in the primary and all ranked secondary end points and in signs and symptoms of moderate-to-severe nail psoriasis versus with placebo and no new safety risks were identified.

BACKGROUND: Psoriasis and obesity are chronic, inflammatory diseases, sharing certain pathophysiological factors. Psoriasis, increasingly viewed as a systemic inflammatory condition, may have various symptoms beyond the skin manifestations. METHODS: This research aimed to explore the connection between body mass index (BMI) and pediatric psoriasis, through a case-control study on 100 psoriasis cases and 100 controls who were matched in terms of age and sex. The percentiles of the BMI by age and sex determined the nutritional status of each patient and control. The severity of psoriasis was evaluated based on the psoriasis area and severity index (PASI), nail involvement based on the nail psoriasis severity index (NAPSI), and quality of life impairment with the dermatology life quality index (DLQI). RESULTS: While no statistically significant relationship was identified between increased BMI and PASI (p = 0.074), the risk of being overweight and obesity was significantly higher in the psoriasis group (OR 6.93, p = 0.003; OR 12.6, p < 0.001, respectively). The BMI increased with the PASI for psoriasis vulgaris but not for psoriasis inverse. No connections were found between disease duration and BMI (p = 0.56) or between BMI and PASI based on sex (p = 0.26). The NAPSI increased significantly with increased BMI (p = 0.000015). CONCLUSIONS: This study highlights the association between elevated BMI, psoriasis diagnosis, and severity of psoriatic onychopathy in pediatric patients, advocating for further large-scale studies to confirm these explorations and increasing awareness for better screening and management of such cases for overweight/obese patients.
ABSTRACT
Nail psoriasis is a chronic, inflammatory condition which is difficult to treat, linked with greater psoriasis severity, and may be associated with anxiety and significant functional impairment of the quality of life. The 1064 nm Nd: YAG laser was reported to yield satisfactory results in the treatment of nail psoriasis.The aim of the study was to assess the clinical and ultrasonographic efficacy of long-pulsed 1064 nm Nd: YAG laser in the treatment of fingernail psoriasis and compare its effect to control fingernails.This intra-patient randomized controlled trial analyzed 86 fingernails collected from 13 patients suffering from cutaneous and nail psoriasis. The nails were randomized into two groups. Group A was treated with Nd: YAG laser once monthly for three sessions while group B served as control. Assessment took place at baseline, 1 and 3 months after the last treatment session. For scoring, the 32-points target NAPSI scoring systems was used. Additionally, two blinded dermatologists' score of improvement, patients' pain assessment by visual analogue score and ultrasonographic assessment were all performed.At the end of follow up, the medians of tNAPSI score, plate definition, matrix thickness, bed thickness and bed vascularity decreased significantly in the Nd: YAG laser treated group in comparison to baseline (p = 0.001, 0.006, 0.039, < 0.001 and 0.010, respectively). While, there was a non-significant reduction in median tNAPSI score in the control group at last follow up, however, ultrasonography recorded a significant reduction in the medians of plate definition, bed thickness and vascularity (p = 0.002, 0.011 and 0.033, respectively) from the baseline. Comparison of the Nd: YAG laser and the control groups showed no significant difference from baseline regarding the medians of tNAPSI, tNAPSI percentile improvement, pits count, blinded evaluation of photographs and ultrasonographic assessments.In conclusion, Nd: YAG laser showed clinical and ultrasonographic improvement in fingernail psoriasis. Ultrasonography is a useful noninvasive tool in diagnosing and monitoring the clinical and even the subclinical changes in nail psoriasis. Nail psoriasis although difficult to treat, may show spontaneous improvement.

Nail psoriasis is a chronic condition characterized by nail dystrophy affecting the nail matrix and bed. The severity of nail psoriasis is commonly assessed using the Nail Psoriasis Severity Index (NAPSI), which evaluates the characteristics and extent of nail involvement. Although the NAPSI is numeric, reproducible, and simple, the assessment process is time-consuming and often challenging to use in real-world clinical settings. To overcome the time-consuming nature of NAPSI assessment, we aimed to develop a deep learning algorithm that can rapidly and reliably evaluate NAPSI, thereby providing numerous clinical and research advantages. We developed a dataset consisting of 7054 single fingernail images cropped from images of the dorsum of the hands of 634 patients with psoriasis. We annotated the eight features of the NAPSI in a single nail using bounding boxes and trained the YOLOv7-based deep learning algorithm using this annotation. The performance of the deep learning algorithm (DLA) was evaluated by comparing the NAPSI estimated using the DLA with the ground truth of the test dataset. The NAPSI evaluated using the DLA differed by 2 points from the ground truth in 98.6% of the images. The accuracy and mean absolute error of the model were 67.6% and 0.449, respectively. The intraclass correlation coefficient was 0.876, indicating good agreement. Our results showed that the DLA can rapidly and accurately evaluate the NAPSI. The rapid and accurate NAPSI assessment by the DLA is not only applicable in clinical settings, but also provides research advantages by enabling rapid NAPSI evaluations of previously collected nail images.
ABSTRACT
Introduction: Treatment of nail psoriasis is challenging. Systemic therapies may be difficult to justify, while topical therapies may be sup-optimal. Triamcinolone acetonide (TA) injections are recommended as first-line therapy in cases with less than 3 nails involved; however, limited studies are available. This study was conducted to evaluate the reduction in NAPSI (Nail Psoriasis Severity Index) with TA injections in patients with isolated nail psoriasis. Methods: A retrospective case record analysis of efficacy and safety of TA (5 mg/mL) nail injections (4-weekly for fingernails, 8-weekly for toenails) was done in 10 patients. NAPSI was evaluated at each visit and treatment endpoint (75% reduction or 10 injections, whichever was earlier). Dropouts and adverse effects were recorded. Results: Among 10 patients (94 involved nails, 61 fingernails, and 33 toenails), 3 patients (30%) dropped out (2, 4, and 5 sessions, respectively), citing procedural pain. Three patients achieved NAPSI-75 (3, 6, and 7 sessions, respectively). Baseline mean NAPSI of 5.03 (4.63 fingernails and 5.78 toenails) dropped to 3.67 (3.13 fingernails and 4.42 toenails) by the 5th injection; and 2.35 (2.13 fingernails and 2.59 toenails) by the 10th injection. Adverse effects included pain (30%), subungual haematoma (1.7%), and proximal nail fold hypopigmentation with mild atrophy (1.1%). Conclusions: TA (5 mg/mL) injections are effective in nail psoriasis and associated with minimal adverse effects.
ABSTRACT
BACKGROUND: Literature concerning clinical signs and frequency of nail psoriasis is incomplete. Recent studies focus only on signs included in the Nail Psoriasis Severity Index (NAPSI). OBJECTIVE: We sought to describe clinical characteristics of fingernail psoriasis in comparison with healthy controls. METHODS: We collected data on 49 patients with fingernail psoriasis who visited our outpatient department and 49 control subjects, through questionnaires and clinical examination. The disease severity was measured by the NAPSI. RESULTS: Mean NAPSI score in patients and control subjects was 26.6 and 3.6, respectively. Most items included in the NAPSI were specific for nail psoriasis. Onycholysis and splinter hemorrhages were most frequently observed. Leukonychia was more frequent in control subjects. Longitudinal ridges and Beau lines are not included in the NAPSI but are significantly more frequently seen in patients than in control subjects. LIMITATIONS: Limited sample size was a limitation. CONCLUSION: The NAPSI was able to discriminate patients with fingernail psoriasis from healthy control subjects. Onycholysis and splinter hemorrhages were the most prevalent fingernail changes in psoriatic patients. Leukonychia was more frequently observed in control subjects, which raises the question of whether leukonychia should remain in the NAPSI. On the other hand, longitudinal ridges and Beau lines occurred more frequently in psoriasis but are not included in the NAPSI.

BACKGROUND: Nail affection is seen in up to 50 % of patients with skin psoriasis, although up to 5% of nail psoriatic patients do not complain of skin affection. Various treatment options are emerging for nail psoriasis such as intense pulsed light Tawfik, 2014). Methylene-blue (M.B) is a phenothiazine dye which is suggested to mediate cell cyto-toxicity by the generation of hydroxyl-radicals which change the intra-cellular calcium homeo-static mechanisms (Lee and Wurster, 1995). OBJECTIVES: Evaluation and comparing the efficacy of I.P.L. and methylene-blue assisted photo-dynamic therapy for treating psoriatic nails. PATIENTS AND METHODS: 20 patients with mild to moderate psoriasis with nail involvement. Sessions were performed once every 2 weeks on all the affected nails for a maximum of 3 months (6 sessions). Nail Psoriasis Severity Index (N.A.P.S.I.) score and photo-documentation were done for all the patients to assess the nail status at the first visit, after two, six sessions and three months after finishing the six session (0 m., 1 m., 3 m. and 6 m.). Nails of the right hand were treated with methylene-blue mediated photo-dynamic therapy using the Intense Pulsed Light (IPL) as the light source, while the left hand received conventional IPL (430-1200 nm) alone. RESULTS: The present study showed that both treatments were effective on nail psoriasis, but MB-PDT was more effective in nail-bed lesions. There was no significant difference regarding patient satisfaction. CONCLUSION: Both Intense Pulsed Light and methylene-blue assisted photo-dynamic therapy were safe, nearly pain-free, easy to use, and effective for treating nail psoriasis. MB-PDT is a new promising strategy for the treatment of nail psoriasis.

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.
ABSTRACT
BACKGROUND: Available network meta-analyses (NMAs) comparing the efficacy of biologics in nail psoriasis (NP) have not included recently approved biologics such as bimekizumab nor have they provided comparisons up to 1 year. OBJECTIVE: We conducted two NMAs that update and extend results from a previous NMA comparing biologics for achieving complete resolution of NP. METHODS: Bayesian NMAs were performed using a generalized linear model with a logit link to model the binary outcome of nail clearance at weeks 24-28 and 48-52. RESULTS: For the NMA at weeks 24-28, which included seven biologics and placebo, the absolute probability of achieving complete resolution of NP was highest for ixekizumab (46.4%; 95% credibility interval [CrI] 35.2-58.0), followed by brodalumab (37.1%; 95% CrI 17.1-62.2) and bimekizumab (30.3%; 95% CrI 12.7-53.9). For the NMA at weeks 48-52, which included six biologics, the absolute probability was highest for ixekizumab (77.2%; 95% CrI 51.1-93.4), followed by adalimumab (75.6%; 95% CrI 61.5-87.3) and brodalumab (71.9%; 95% CrI 38.4-93.2). CONCLUSION: Among biologics included in these two NMAs, ixekizumab has the highest absolute probability of achieving complete resolution of NP. Results may help to inform treatment decisions for patients with NP.

Background: As face is the index of the mind, so is the nail the index to health, as the nail is capable of mounting only a limited number of reaction patterns to the large number of disorders affecting it. Dermoscopy is thus a valuable aid not only in enhancing visible nail features but also in revealing cryptic features of diagnostic value. Aims: To study the clinical and dermoscopic features in nails of papulosquamous disorders and correlate it with disease severity. Methods and Material: This was a cross-sectional study with convenient sampling. After obtaining ethical clearance, according to inclusion and exclusion criteria, papulosquamous disorders were enrolled in the study. Finger nails and toe nails were numbered 1-10. Detailed clinical examination was done. Wet and dry dermoscopic examination was made in both polarised and non-polarised mode using ultrasound (USG) gel. Psoriasis area and severity index (PASI) and body surface area (BSA) were compared with nail changes. Statistical analysis of data was performed using the Statistical Package for the Social Sciences (SPSS) version 26. Results: Out of 203 patients, 117 were male. Psoriasis was the most common disease (55.6%). A total of 65.51% of patients had nail changes. Pitting was the most common finding in psoriasis, both dermoscopically and clinically. Splinter haemorrhage, oil drop, dilated capillaries, and pseudofibre sign were detected better on dermoscopy (P < 0.05). Positive correlation was found between PASI and nail psoriasis severity index (NAPSI). A strong correlation was also found between clinical (cNAPSI) and dermoscopic (dNAPSI). Thinning was the most common in lichen planus. No relation between BSA and nail changes was observed. Conclusions: Dermoscopy is thus a valuable aid not only in enhancing visible nail features but also in revealing cryptic features of diagnostic value and reducing the requirement for invasive procedures like nail biopsies, early diagnosis, directing management.
ABSTRACT
Tildrakizumab, an IL-23 inhibitor, is effective and safe for the improvement of moderate-to-severe chronic plaque psoriasis. However, little evidence is available on the use of this biologic in psoriasis in difficult-to-treat locations. In this retrospective analysis, we treated patients with 100 mg tildrakizumab at Day 0, after 4 weeks and every 12 weeks thereafter. Disease severity and treatment response was assessed by the Psoriasis Area and Severity Index (PASI), the static Physician's Global Assessment of Genitalia (sPGA-G), the Psoriasis Scalp Severity Index (PSSI), Nail Psoriasis Severity Index (NAPSI) and the Palmoplantar Psoriasis Area and Severity Index (ppPASI) at baseline and after 4, 12 and 28 weeks. We followed 18 patients (mean age 49.1 ± 12.7 years, 61.1% male) with psoriasis localized to the genital region (N = 7), scalp (N = 6), nails (N = 5) and palmar/plantar areas (N = 7). PASI score decreased from 11.5 at baseline to 3.1 and 2.4 at 12 and 28 weeks. Tildrakizumab treatment decreased sPGA-G (3.3 to 0.2), PSSI (36.2 to 2.7), NAPSI (48.4 to 15.7) and ppPASI (5.3 to 0) from baseline to 28 weeks, respectively. Data from this real-life retrospective analysis shows that tildrakizumab is an effective option for the management of psoriasis in difficult-to-treat areas.
ABSTRACT
Nail psoriasis significantly impacts the quality of life in patients with psoriasis, which affects approximately 2-3% of the population worldwide. Disease severity measures are essential in guiding treatment and evaluation of therapeutic efficacy. However, due to subsidy, convenience and low costs of health care in Taiwan, doctor usually needs to manage nearly hundreds of patients in single outpatient clinic, leading to difficulty in performing complex assessment tools. For instance, Nail Psoriasis Severity index (NAPSI) is used by dermatologists to measure the severity of nail psoriasis in clinical trials, but its calculation is quite time-consuming, which hampers its application in daily clinical practice. Therefore, we developed a simple, fast and automatic system for the assessment of nail psoriasis severity by constructing a standard photography capturing system combined with utilizing one of the deep learning architectures, mask R-CNN. This system not only assist doctors in capturing signs of disease and normal skin, but also able to extract features without pre-processing of image data. Expectantly, the system could help dermatologists make accurate diagnosis, assessment as well as provide precise treatment decision more efficiently.
ABSTRACT
BACKGROUND: Nail psoriasis (NP) is common and of high importance in patients with psoriasis. Complete resolution of NP at week 24â26 is an unambiguous nail outcome accessible for indirect treatment comparison of biologics. OBJECTIVE: To evaluate the comparative efficacy of approved biologics in achieving complete resolution of NP at week 24â26. METHODS: A network meta-analysis (NMA) was conducted to indirectly compare the efficacy of six biologics in achieving complete resolution of NP at week 24â26 in patients with moderate-to-severe psoriasis and concomitant NP. Complete resolution of NP was defined as a score of zero on the Nail Psoriasis Severity Index (NAPSI), modified NAPSI (mNAPSI) or Physician's Global Assessment of Fingernails (PGA-F). RESULTS: The probability of achieving complete resolution of NP was highest for ixekizumab (46.5%; 95% credibility interval [CrI] 35.1â58.0; Surface Under the Cumulative RAnking curve [SUCRA] 97%), followed by brodalumab (37.0%; 17.0â61.0; 79%), adalimumab (28.3%; 24.4â32.4; 62%), guselkumab (27.7%; 21.1â35.1; 58%), ustekinumab (20.8%; 10.2â35.2; 37%), and infliximab (0.8%; 0.0â8.9; 17%). CONCLUSION: In patients with moderate-to-severe psoriasis and concomitant NP, ixekizumab has the greatest likelihood among approved biologics of achieving complete resolution of NP at week 24â26. Findings should be interpreted carefully because of inherent study limitations.

Objective: Safe, effective, long-term oral therapies are needed for plaque psoriasis. This study aimed to assess the safety and effectiveness of tepilamide fumarate (a fumaric acid ester) extended-release tablets. Methods: This Phase IIb, randomized, double-blind, placebo-controlled, 24-week, multicenter study treated adults with moderate-to-severe plaque psoriasis with tepilamide fumarate 400 mg once (QD) or twice daily (BID), 600 mg BID, or placebo. Coprimary endpoints were the proportion of patients achieving ≥75% reduction in the Psoriasis Area and Severity Index (PASI-75) and Investigator's Global Assessment (IGA) of clear or almost clear (≥2 points' reduction). Results: A total of 426 patients were randomized (mean age 49.6 [±13.0] years). There was a ≥75% PASI reduction in 39.7%, 47.2%, 44.3%, and 20.0% in the 400 mg QD, 400 mg BID, 600 mg BID, and placebo groups, respectively; IGA treatment success was 35.7%, 41.4%, 44.4%, and 22.0%, respectively. Between 50%-66% of tepilamide fumarate and 48% of placebo patients experienced ≥1 treatment-emergent adverse event. Gastrointestinal intolerance (20%-42%), infection (6%-18%), and decreased lymphocyte count (4%-9%) were more common with tepilamide fumarate. Limitations: High placebo response somewhat limits the utility of these findings. Conclusion: Patients with moderate-to-severe plaque psoriasis treated with oral tepilamide fumarate demonstrated positive response.
ABSTRACT
BACKGROUND: Nail are important for both function and esthetic appearance and although they represent a small body surface area, dermatologic disorders affecting the nails can have a detrimental effect to the patient. Deciding on the best systemic antipsoriatic drug to treat nail psoriasis can be difficult due to the lack of nail data on their Food and Drug Administration-approved labels, as well as the variety of scoring systems used for nail psoriasis. METHODS: We performed a literature review and included randomized control trials or articles based on randomized control trials for different systemic antipsoriatic drugs. Only articles and studies utilizing Nail Psoriasis Severity Index (NAPSI) or target NAPSI as outcome measures were included. Data was taken directly from articles, directly from clincaltrials.gov or directly from data on file at various pharmaceutical companies. RESULTS: Data for NAPSI and PASI were collected for 10 antipsoriatic drugs including three oral medications and seven biologic agents. We found that NAPSI or target NAPSI was strongly predicted based on the change in PASI and duration of treatment (R2 = 0.71, p = .0002). PASI alone (R2 = 0.52, p = .001) and duration alone (R2 = 0.21, p = .07) predict NAPSI response. CONCLUSION: According to this model, there is a relationship between skin and nail response, with improvement in nails correlating with improvement in skin and longer duration of treatment.

BACKGROUND: Intralesional injection of corticosteroid (ILIS) and pulsed-dye laser (PDL) have been used in nail psoriasis treatment with variable outcomes. OBJECTIVE: We sought to compare the efficacy of ILIS to PDL for the treatment of psoriatic fingernails using a dermoscope in the assessment and follow-up. METHODS: This study included 30 patients with bilateral nail psoriasis. The fingernails of one hand were treated with PDL, whereas ILIS was used to treat the fingernails of the other hand. One psoriatic nail was left alone as a control. Every patient received four treatment sessions once every month. Efficacy was recorded clinically using the Nail Psoriasis Severity Index (NAPSI) and by a dermoscope before treatment (baseline) and at eight, 24, and 36 weeks after treatment. RESULTS: The assessment by NAPSI revealed improvements of 22.24% and 24.11% occurred in the laser group and the intralesional steroid group, respectively. Also, the dermoscopic assessments revealed an improvement of 18.33% in the laser group versus that of 21.69% in the ILES. No significant difference was found between the two groups. CONCLUSION: Both PDL and ILIS are considered safe treatments for nail psoriasis, yielding nearly equal results. The dermoscope is a reliable tool for the diagnosis and follow-up of nail psoriasis treatment.
