RESUMO
The nail is an important characteristic in the context of psoriasis. Nail psoriasis exhibits several clinical manifestations. Since the development of the Nail Psoriasis Severity Index (NAPSI) score assessment tool for evaluating the severity of nail psoriasis, nail matrix symptoms such as pitting, leukonychia, crumbling, and red spots have been observed in the lunula. Nail bed symptoms include onycholysis, subungual hyperkeratosis, oil spots, and splinter hemorrhage. However, Beau's lines and nail fold psoriasis, which are not included in this assessment tool, should be considered essential symptoms for indicating the activity of nail psoriasis. Although NAPSI is the most widely used tool for assessing the severity of nail psoriasis, it has uncontrolled limitations. Although other assessment tools have been developed, none have successfully replaced the NAPSI. In clinical trials for nail psoriasis, the NAPSI is used in various forms, such as improvement rates, changes in the mean NAPSI score, and achievement rates of NAPSI 75. Consequently, caution is warranted when interpreting the clinical trial results related to nail psoriasis improvement.
RESUMO
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.
RESUMO
Small plaque psoriasis is the typical form of chronic plaque psoriasis affecting adults in South Korea. The effectiveness of calcipotriol/betamethasone dipropionate (Cal/BD) aerosol foam for large and small psoriasis plaques has not previously been examined. We performed a post hoc analysis of a recent, 4-week observational study of Cal/BD aerosol foam use in routine clinical practice in South Korea. Investigator Global Assessment response ([IGA] 0/1 at week 4), Patient Global Assessment response ([PaGA] 0/1 at week 4), change in Psoriasis Area and Severity Index (PASI), changes in psoriasis symptom scores, change in the Dermatology Life Quality Index (DLQI), and the proportion of patients achieving DLQI ≤5 were analyzed for patients with small (≤5 cm; n = 131) or large (>5 cm; n = 35) baseline plaque size. IGA response rates were similar for patients with small and large plaques (59.5% and 51.4% respectively). Similarly, there was no significant difference between the small and large groups in mean change in PASI (-2.20 vs -3.34), the proportions of patients with DLQI ≤5 (62.3% vs 54.3%) or PaGA 0/1 (29.2% vs 40.0%). Mean improvements in DLQI (-4.04 vs -6.20) and in psoriasis symptoms including itching (-1.50 vs -2.83), sleep loss (-0.67 vs -1.89), dryness (-1.57 vs -2.97), scaling (-1.21 vs -3.57), and redness (-1.17 vs -3.11) were greater in patients with large plaques than those with small plaques. Itching and DLQI differences were not statistically significant after adjustment for baseline characteristics. Stratification by body surface area affected eliminated statistically significant differences between the groups for most outcomes. In conclusion, this analysis suggests that Cal/BD aerosol foam is an effective, well-accepted treatment for adult patients with the small plaques typical of chronic plaque psoriasis in South Korea, as well as for those with large plaques.

Patients with psoriasis frequently have comorbidities, which are linked to higher mortality rates. An in-depth investigation of comorbidities and their effects on health can help improve the management of patients with psoriasis. We conducted a comprehensive and unbiased investigation of comorbidities in patients with psoriasis and explored the pattern of association between comorbidities. A nationwide population-based study included 384 914 patients with psoriasis and 384 914 matched controls between 2011 and 2021. We used automated mass screening of all diagnostic codes to identify psoriasis-associated comorbidities and applied association rule analysis to explore the patterns of comorbidity associations in patients with psoriasis. Patients with psoriasis had an increased risk of autoimmunity-related diseases such as inflammatory arthritis, Crohn's disease, type 1 diabetes, and acute myocardial infarction. The comorbidities of patients with psoriasis with a history of cardiovascular events demonstrated strong interrelationships with other cardiovascular risk factors including type 2 diabetes mellitus, essential hypertension, and dyslipidemia. We also found comorbidities, such as malignant skin tumors and kidney and liver diseases, which could have adverse effects of anti-psoriasis therapy. In contrast, patients with psoriasis showed a decreased association with upper respiratory tract infection. Our results imply that comorbidities in patients with psoriasis are associated with the systemic inflammation of psoriasis and the detrimental effects of its treatment. Furthermore, we found patterns of associations between the cardiovascular risk factors and psoriasis. Mass screening and association analyses using large-scale databases can be used to investigate impartially the comorbidities of psoriasis and other diseases.

Omalizumab is effective in chronic spontaneous urticaria unresponsive to antihistamines. Of the licensed dosing schedules, Korean patients prefer a low dose, of 150 mg/month, for financial reasons. However, real-world experiences of low-dose omalizumab consumption have not been reported. The aim of this retrospective study was to assess the treatment outcomes and long-term clinical course of patients with chronic spontaneous urticaria who were treated with low-dose omalizumab. The study included 179 patients aged ≥ 20 years who were treated with omalizumab 150 mg/month for ≥ 12 weeks. Baseline disease activity was mild, moderate, and severe in 54.7%, 35.2%, and 10.1% of patients, respectively. A complete response was observed in 133 patients at 12 weeks, among whom 88 patients showed early responses within 4 weeks. Overall, 158 patients finally achieved a complete response. Multivariate analyses revealed that baseline disease activity is more likely to be mild in patients who experience early and final complete responses. The absence of atopic comorbidities correlated with an early response. Smoking was associated with a final complete response. This study shows that low-dose omalizumab provides favourable treatment outcomes in antihistamine-refractory chronic spontaneous urticaria. Disease severity, atopic comorbidity, and smoking may be predictive factors for studying the response to omalizumab.

The effect of antipsoriatic therapy on cardio-cerebrovascular disease (CCVD) is not well described. Thus, we performed a population-based nested case-control study to investigate the effect of systemic antipsoriatic therapy on CCVD in psoriasis patients. Using nationwide cohort data from the Korean National Health Insurance Claims database, newly diagnosed psoriasis patients were identified. Among the enrolled participants, postenrollment development of CCVD events (ischemic heart disease, myocardial infarction, cerebral infarction, and cerebral hemorrhage) was investigated. To evaluate the effect of systemic antipsoriatic therapy on CCVD risk, we calculated the proportion of the treatment period with systemic antipsoriatic therapy during the study period (PTP [%]: the sum of all systemic antipsoriatic therapy durations divided by total observation period). Among 251 813 participants, 6262 experienced CCVD events during the study period (CCVD group). Controls included 245 551 patients without CCVD history during the study period (non-CCVD group). The non-CCVD group had greater PTP than the CCVD group (CCVD 2.12 ± 7.92, non-CCVD 2.64 ± 9.64; P < 0.001). In multiple logistic regression analysis, PTP was inversely associated with the CCVD risk after adjusting for age, sex, diabetes, hypertension, and dyslipidemia. A 10% increase in PTP reduced CCVD risk by 0.96 (95% confidence interval 0.93 to 0.99). Reduced CCVD risk was robust for both conventional antipsoriatic therapy and biologics. Our study found that systemic antipsoriatic therapy use was inversely associated with CCVD risk in psoriasis patients. These findings suggested that systemic antipsoriatic therapy could reduce CCVD development in patients with psoriasis.

Patients with psoriasis were randomized to guselkumab, placebo or adalimumab in the VOYAGE 1 and VOYAGE 2 studies. In this post hoc analysis, difficult-to-treat psoriasis regions in the Asian subpopulation for both the guselkumab and adalimumab groups were compared with placebo at week 16 and the active treatment groups were compared at week 24. Endpoints included patients achieving scores of 0 or 1 (clear or near clear) or 0 (clear) on the scalp-specific Investigator's Global Assessment (ss-IGA), Physician's Global Assessment of the hands and/or feet (hf-PGA), and fingernail PGA (f-PGA), and percentage improvement in target Nail Psoriasis Severity Index (NAPSI) score through week 24. Efficacy was also assessed by prior biologic experience at baseline. A total of 199 eligible Asian patients were included. The proportion of patients achieving "clear" or "near clear" with guselkumab was superior to adalimumab at week 24 for scalp psoriasis ss-IGA (Asian patients, 72 [85.7%] vs 35 [67.3%], P = 0.004), hands and/or feet psoriasis hf-PGA (29 [82.9%] vs 16 [61.5%], P = 0.054), and similar for fingernail psoriasis f-PGA (28 [63.6%] vs 17 [54.8%], P = 0.412). Guselkumab mean improvements in NAPSI were comparable to adalimumab (39.9% vs 35.9%, P = 0.618). Overall, the complete clearance response of scalp, and hands and/or feet at week 24 occurred in a greater proportion of patients in the guselkumab group, irrespective of baseline biologic status (treatment-naïve or treatment-experienced). Guselkumab was superior to adalimumab for the treatment of scalp, and hands and/or feet psoriasis, and proportionally higher for fingernail psoriasis. Findings were comparable to the global study population.

BACKGROUND: Evidence for the association between psoriasis and uveitis according to the severity of psoriasis including psoriatic arthritis (PsA) and type of uveitis is lacking, and there are no data on the frequency or timing of recurrence of uveitis in patients with psoriasis. OBJECTIVES: We aimed to evaluate the risk of first occurrence and recurrence of uveitis in patients with psoriasis in the Korean population. We further evaluated the risk of uveitis according to the severity of psoriasis, comorbidity of PsA and location of uveitis. METHODS: In a nationwide retrospective cohort study, we compared 317,940 adult patients who had psoriasis with 635,880 matched controls. Incidence rates (IRs) and estimated IR ratios of the first occurrence and recurrence of uveitis were calculated using survival analysis and Poisson regression, respectively. RESULTS: The rate of uveitis incidence and uveitis recurrence in patients with psoriasis was 1.18 and 2.31 per 1000 person-years, respectively. Compared to the controls, the IR ratios of development and recurrence of uveitis in patients with psoriasis were 1.14 (95% CI 1.08, 1.2) and 1.16 (95% CI 1.12, 1.21), respectively. The recurrence rate of uveitis was highest within 3 years after the onset of psoriasis. The corresponding IR ratios for uveitis recurrence in patients with mild psoriasis, severe psoriasis and PsA were 1.11 (1.06, 1.16), 1.24 (1.16, 1.33) and 1.49 (1.31, 1.7), respectively. Patients with psoriasis had an increased risk of recurrence of anterior uveitis, and patients with both psoriasis and PsA had an increased risk of recurrence of both anterior-uveitis and panuveitis. CONCLUSIONS: Patients with psoriasis had a higher risk of both development and recurrence of uveitis, especially with severe psoriasis and PsA. The timing of uveitis recurrence was related to the onset of psoriasis, and patients who had psoriasis with PsA had an increased risk of vision-threatening panuveitis.

Palmoplantar pustulosis (PPP) is a variant of pustular psoriasis involving the palms and soles. The severity of PPP is usually evaluated using the Palmoplantar Pustulosis Area and Severity Index (PPPASI). Among the components of the PPPASI, the area of the involved lesion is evaluated differently by raters, who generally make a rough estimate using the eye and not through a specific calculation. To overcome inconsistent evaluation of the area subscore of PPPASI by human raters, we developed and validated deep-learning-based algorithms to enable automated and reliable assessment of the area involved in PPP to provide clinical advantages. In this study, we developed a dataset of 611 images of the palms and soles of 153 patients with PPP. We evaluated the area of the lesion by dividing the number of pixels in the area involved in PPP by the number of pixels in the area of the palms or soles. Using attention U-net, we developed two convolutional neural network (CNN) models that can evaluate the percentage of the affected area (%) and subsequently assign a score ranging from 0 to 6. The area subscore of PPPASI evaluated by the deep-learning algorithm was same or differed by 1-point from the subscore of ground truth in 98.8% of the images. The intraclass correlation coefficient between the CNN and ground truth was 0.879, indicating good agreement. The accuracy and mean absolute error of the model were 66.7% and 0.344, respectively. In a Bland-Altman plot, most of the differences in the percentage of the affected area lay between the 95% confidence interval with a mean difference of 0 and a standard deviation of 0.2. The deep-learning algorithm can provide several clinical advantages by objectively evaluating the components of the PPPASI without concern for disagreement between clinicians. The algorithms further enable cumulative clinical data acquisition related to PPP severity.

BACKGROUND: This aim of this study was to develop an objective tool for rating submental fat applied to Koreans. METHODS: The study was conducted between April 2019 and October 2019. A total of 92 subjects were enrolled in the study. Clinical photos of the subjects were categorized using validated CR-SMFRS by three plastic surgeons and one dermatologist. The categorized photos were then shown to six different plastic surgeons for evaluation. RESULTS: The Cohen's kappa value for the six raters were 0.830, 0.742, 0.703, 0.907, 0.862, and 0.793 with statistical significance (p < 0.001). ICC value was between 0.860 and 0.966 (p < 0.001). Since the Cohen's value and ICC were above 0.6 for all raters, the ratings performed by all six raters were used in the analysis. The ICC values between raters were between 0.899 and 0.902. CONCLUSIONS: We came up with a set of reference photos that can be used for submental fat rating scale applicable to Korean subjects. LEVEL OF EVIDENCE: II.
RESUMO
Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous drug adverse reaction characterized by various cutaneous and systemic manifestations. However, reports on the various patterns of alopecia after DRESS are lacking. Thus, we aimed to describe cases of alopecia after DRESS and review the literature. This multicentric retrospective study reviewed the records of 182 patients diagnosed with DRESS from 2009 to 2021; of these, 10 who had alopecia after DRESS were included. Patients were diagnosed with permanent alopecia (n = 4), telogen effluvium (n = 5), and alopecia areata (n = 1), and were treated with topical minoxidil or alfatradiol (6; 60%), topical corticosteroids (3; 30%), dietary supplements (6; 60%), systemic corticosteroids (1; 10%), and intralesional corticosteroid injection (2; 20%). Although patients with permanent alopecia did not show hair regrowth after 6 months, those with telogen effluvium and alopecia areata experienced marked clinical improvement within 6 months. Various types of alopecia can persist over an extended period, even after the resolution of an acute episode of DRESS.

A reduction in the unnecessary use of antibiotic prophylaxis can prevent antibiotic resistance and adverse drug events. We aimed to evaluate the effects of implementing clinical pathways (CPs) on adherence to a systematic and appropriate duration of antibiotic prophylaxis. We identified 61 eligible CPs and a total of 44,062 patients who underwent elective surgeries associated with CPs. The Poisson mixed model with an interrupted time-series analysis frame was applied to the patient-level data. This enabled a comparison of the adherence rate before and after CP implementation. Furthermore, we examined the effect of application or completion of CP on the adherence rate after implementation. Adherence to the antibiotic prophylaxis guideline substantially increased (incident rate ratio [IRR] 8.05; 95 confidence interval [CI] 2.64-24.55), compared with that before implementation. Following the implementation into the electronic entry system, we observed an improved adherence not only in CP completion but also in attempted CP execution (IRR of the executed but not completed cases 1.54; 95% CI 1.17-2.04; IRR of the executed and competed cases, 1.94; 95% CI 1.4-2.69). The implementation of CP into the electronic prescribing system was associated with a significant increase in the appropriate use of antibiotic prophylaxis among patients who underwent elective surgeries. The results suggest that a computer-assisted CP system for electronic health records could improve antibiotic adherence without significant expense.

Cyclosporine (CsA) is an immunosuppressive agent that specifically inhibits T cell-related immune responses. There is little evidence regarding the association between low-dose CsA administration and abnormal hepatic function in dermatology patients. This study aimed to examine the association between the cumulative dose of CsA and liver enzyme abnormalities obtained from peripheral blood tests in patients with skin diseases. A retrospective single-center study of 697 patients who were prescribed CsA for skin disease in the outpatient dermatology clinic between 2015 and 2019 were performed. Multiple logistic regression with confounder adjustment was performed to assess the association between the cumulative dose of CsA and liver enzyme abnormalities. Compared to patients with the lowest cumulative dose of CsA (Ë7.0 g), patients with the highest cumulative dose of CsA (≥30.6 g) were significantly associated with an increased likelihood of developing liver enzyme abnormalities (odds ratio [OR] = 1.96; 95% confidence interval [CI] = 1.02-3.79). In the stratified analysis, patients with the highest cumulative dose of CsA (≥30.6 g) were significantly associated with a 1.5-or higher alanine aminotransferase elevation from baseline (OR = 2.26, CI = 1.08-4.73). Patients prescribed long-term, low-dose CsA up to a high cumulative dose (≥30.6 g) may be associated with an increased risk of developing liver enzyme abnormalities. However, these liver enzyme elevations were not severe in magnitude and were reversible.

An innovative foam formulation for the fixed-dose combination of calcipotriol and betamethasone dipropionate (Cal/BD) has recently become available for the treatment of psoriasis vulgaris. Observational studies of patients treated with Cal/BD foam in routine practice have been conducted in several Western countries, but there are limited data on outcomes in Asian patients. We performed a prospective, open-label, noncomparative, noninterventional study to investigate treatment outcomes and satisfaction in adult patients receiving Cal/BD foam for psoriasis vulgaris in dermatological centers and outpatient clinics in Korea. Data were collected at the time of enrollment (Visit 1) and at a routine clinic visit ~4 weeks later (Visit 2). In total, 218 patients were enrolled, of whom 175 were included in the safety analysis set (58.9% male; mean age ± standard deviation 46.7 ± 15.1 years; use of Cal/BD foam at least once daily 74.3%). Of the safety analysis set, 166 patients had at least mild psoriasis (Investigator Global Assessment [IGA] ≥ 2) and were analyzed for treatment outcomes and satisfaction. Of the 166 patients, 71.7% had mild psoriasis (IGA 2) at baseline. The majority (57.8%) achieved an IGA of 0/1 (clear/almost clear) at Visit 2. The Psoriasis Area Severity Index (PASI) and Dermatology Life Quality Index (DLQI) showed significant improvements from Visit 1 to Visit 2 (PASI -2.4 ± 3.0, DLQI -4.5 ± 5.2, both P < 0.0001). Most of the patients were satisfied with the Cal/BD foam treatment; 77.0%, 60.0%, and 73.9% were satisfied in terms of effectiveness, ease of use, and global satisfaction, respectively. In the safety analysis set, adverse events were reported in 13 patients (7.4%). In conclusion, this first Korean real-world study of Cal/BD foam shows improvement of lesions and health-related quality of life after 4 weeks of treatment, with high global satisfaction and good overall tolerability and safety.

Background: Although patients with psoriasis have an increased risk of cancers, little is known about the risk of psoriasis in cancer patients. Objective: We aimed to comparatively analyze the incidence and risk factors of psoriasis in gastric cancer patients who underwent gastrectomy and in the general population. Methods: A nationwide retrospective cohort of 52,608 gastric cancer survivors (2007~2015) was compared to 123,438 matched controls from the general population to estimate the incidence and hazard ratio (HR) of new-onset psoriasis. We also calculated the HRs for psoriasis according to adjuvant cancer treatment, obesity, and vitamin B12 supplementation in gastric cancer survivors. Results: During a mean follow-up of 6.85 years, 645 of the 52,608 gastric cancer patients developed psoriasis, while 1,806 in the 123,438 matched control group developed psoriasis. Gastric cancer patients had a decreased risk of psoriasis (HR, 0.86; 95% confidence interval, 0.79~0.94), especially those who underwent subtotal gastrectomy. We found that vitamin B12 supplementation for more than 3 years had an additive effect on decreasing the risk of psoriasis in gastric cancer patients who underwent subtotal gastrectomy. Total gastrectomy, radio/chemotherapy, and obesity did not affect the risk of psoriasis in gastric cancer survivors. Conclusion: The incidence of psoriasis is slightly lower in gastric cancer survivors than in the general population. Our results suggest that the development of psoriasis may be reduced by removing the source of systemic inflammation caused by Helicobacter pylori infection through subtotal gastrectomy in gastric cancer survivors.
RESUMO
Pustulotic arthro-osteitis (PAO) has been studied primarily in Japan. However, there is a lack of research regarding its clinical features among large populations in other countries and it is often believed to be similar to psoriatic arthritis (PsA). Although the association between psoriasis (PsO) and palmoplantar pustulosis (PPP) is debatable, differences in the clinical characteristics between PsA and PAO might support the notion that PsO and PPP are distinct entities. This study aimed to investigate the clinical characteristics of PAO in Korean patients and to compare them with those of PsA. We retrospectively reviewed the medical records of patients diagnosed with PPP, PAO, and PsA. Among 266 patients with PPP, 13.2% had PAO. Unlike Japanese patients with PAO, Korean patients had a relatively lower involvement of the chest wall. PAO patients demonstrated lower age of onset, higher proportion of females, and higher severity of cutaneous eruptions compared to PPP patients without PAO, but the differences were not statistically significant. Female predominance was prominent in PAO compared to PsA. Cutaneous eruptions occurred earlier than joint symptoms in 83.5% of the patients with PsA and in 42.9% of the patients with PAO. PAO involved axial joints more frequently compared to PsA, especially the chest wall and spine. PsA mainly involved the peripheral joints, especially the metacarpophalangeal joints and distal interphalangeal joints of the hands and feet. In conclusion, PAO and PsA exhibited different demographics and locations of joint involvement, supporting the notion that PPP and PsO are separate disorders. Many PAO patients presented with joint symptoms before the appearance of skin eruptions, underlining the important role of dermatologists in recognizing PAO among PPP patients. Physicians should be aware of the characteristics of PAO while treating patients with PPP.

BACKGROUND: In psoriasis treatment, not all body regions improve simultaneously after clinical interventions. OBJECTIVE: This study was aimed at evaluating clinical responses across body regions, which may differentially influence patient treatment plans. METHODS: This prospective, observational, and multi-center study was conducted in Koreans who adhered to ustekinumab treatment based on criteria per local label and reimbursement guidelines. A total of 581 were included in this analysis. RESULTS: The mean (±standard deviation) psoriasis area severity index (PASI) score at baseline, age, disease duration, and body surface area (%) were 18.9±9.69, 44.2±13.29 years, 11.3±9.65 years, and 27.8±17.83, respectively. Across the head and neck, upper extremities, trunk, and lower extremities, the correlation between the PASI sub-scores for the upper and lower extremities was the highest (r=0.680). The mean PASI sub-score for the lower extremities was the highest at baseline. PASI90 and PASI100 scores were the highest for the head and neck region, indicating the highest response rates, while those for the lower extremities were consistently low at all visits. CONCLUSION: We found differences in regional ustekinumab responses, with the lower extremities being the most difficult to treat. These findings should be considered in psoriasis treatment.
RESUMO
BACKGROUND: The phase 3 studies, VOYAGE 1 and 2, were conducted to assess guselkumab in the treatment of patients with moderate-to-severe psoriasis. OBJECTIVES: To investigate the efficacy and safety of guselkumab in Korean patients. METHODS: The Korean sub-population of VOYAGE 1 and 2 study patients were included in this analysis. Efficacy and safety were evaluated through Weeks 24 and 28, respectively. RESULTS: Of 126 randomized Korean patients, 30, 63, and 33 received placebo, guselkumab, and adalimumab, respectively. At Week 16, guselkumab was superior to placebo in achieving an Investigator's Global Assessment (IGA) score of 0 or 1 (cleared or minimal; 90.5 vs. 20.0%, p<.001) and a Psoriasis Area and Severity Index (PASI) 90 response (71.4 vs. 3.3%, p<.001). At week 24, a significantly higher proportion of guselkumab-treated patients achieved PASI 75 and IGA 0 (clear skin) responses compared to adalimumab-treated patients (PASI 75: 93.7 vs. 66.7%, p<.001; IGA 0: 52.4 vs. 21.2%, p=.004). Through Week 28, guselkumab and adalimumab showed comparable safety profiles. CONCLUSION: The efficacy and safety of guselkumab in Korean psoriasis patients through 28 weeks were consistent with findings for the overall VOYAGE 1 and 2 study population.

To our knowledge, there have been no previous reports of granulomatous periorificial dermatitis (GPD) in adult patients in contrast to childhood GPD (CGPD). We report cases of 9 adult patients with GPD with regards to the clinical and histopathological characteristics and their management. GPD in adults may be an entity that is actually underdiagnosed, especially in middle-aged females. It is a benign disorder, albeit requiring a relatively long-term treatment. Unlike CGPD, GPD in adults is frequently accompanied by pruritus with predilection for the eyelid and should be treated initially with oral medication.
RESUMO
ABSTRACT: Although ustekinumab (UST) shows excellent efficacy in treating psoriasis, not all patients have a complete clearance rate. The purpose of this study was to investigate the histopathological characteristics of refractory psoriasis lesions in patients with excellent response to UST. Fifty-seven patients with newly diagnosed psoriasis and 66 patients with a 75% reduction in the Psoriasis Area and Severity Index score after UST treatment were included. Computer-aided image analysis was performed to measure the epidermal thickness, horny layer thickness, number of dermal vessels, and dermal inflammatory cell infiltration rate. Parakeratosis was scored using a 4-point scale. These measurements were compared between the refractory lesions of UST-treated patients and the untreated lesions of newly diagnosed patients after the adjustment for confounding factors. The dermal inflammatory cell infiltration rate was significantly lower in the refractory lesions (P = 0.022). Meanwhile, the epidermal thickness, horny layer thickness, grade of parakeratosis, and dermal vessel count did not differ between the groups (P = 0.125, 0.719, 0.542, and 0.758, respectively). Subgroup analyses were performed within the UST-treated group after dividing them into 2 groups according to the number of treatments or treatment response rates. None of these features were significantly different between the subgroups. This study suggests that the reduction of dermal inflammation by UST was not sufficient to ameliorate the epidermal changes and implies the role of the interleukin-23-independent downstream cytokine pathway in causing the refractory lesions among patients who responded well to UST. The continuation of UST treatment might not further improve epidermal alterations.
