RESUMEN
BACKGROUND: Many patients with ulcerative colitis (UC) gain weight after treatment. However, the clinical significance of weight gain in these patients remains unclear. This study aimed to evaluate body weight changes after treatment in patients newly diagnosed with moderate-to-severe UC and their effects on patients' prognosis. METHODS: The change in weight between diagnosis and 1 year after treatment in 212 patients enrolled in the MOSAIK cohort (mean age, 40 years; males, 60%) was analyzed. Significant weight gain was defined as a weight increase of ≥ 5% from the baseline at 1 year. Factors associated with significant weight gain and the effect of significant weight gain on the risk of major adverse outcomes (clinical relapse, hospitalization, and new use of steroids or biologics) during a follow-up period of 20 months were evaluated. RESULTS: Mean weight gain at 1 year was 1.7 ± 4.2 kg. The proportion of overweight/obese patients increased by 9.0% from 37.9% to 46.9%. Thirty-two percent had significant weight gain; extensive colitis at diagnosis was the only factor associated with significant weight gain (odds ratio 6.5, 95% confidence interval 1.4-31.0, p = 0.006). In multivariable analysis, significant weight gain was not associated with the risk of major adverse outcomes. Weight loss symptoms at diagnosis were associated with an increased risk for new steroid use after 1 year. CONCLUSIONS: Approximately one-third of patients with moderate-to-severe UC had significant weight gain after 1 year of treatment. However, significant weight gain was not associated with the patient's prognosis.

BACKGROUND AND AIM: No inception cohort study has ever evaluated the early course of moderate-to-severe ulcerative colitis (UC) within 1 year of diagnosis in the non-Caucasian population. We aimed to investigate the early clinical course of moderate-to-severe UC patients in terms of remission, relapse, UC-related hospitalizations, colectomy, mortality, and overall use of medications. METHODS: In the MOSAIK inception cohort, which is an ongoing multicenter, prospective, hospital-based, observational cohort, 354 patients with moderate-to-severe UC were followed up for 1 year. Main outcomes of UC and predictive factors for medication use over the course of 1 year were evaluated. RESULT: Among 354 patients, 276 (78.0%) patients were followed up for 1 year. The rates of remission, relapse, UC-related hospitalizations, and proximal disease extension were 95.3%, 39.6%, 15.2%, and 12.3%, respectively. Systemic corticosteroids, thiopurines, and biologics were administered to 61.2%, 30.4%, and 10.5% of patients, respectively, throughout 1 year. One year after, 58.2% patients experienced remission or mild endoscopic activity. Overall disease courses did not show much difference according to moderate or severe disease activity at baseline. In addition, no colectomy and mortality were observed for 1 year. Predictive factors for medication use included disease severity, disease extent, endoscopic severity, and presence of periappendiceal inflammation at baseline for corticosteroid, disease extent and initial corticosteroid use for thiopurine, and only initial corticosteroid use for biologics. CONCLUSION: Korean patients with moderate-to-severe UC may have more favorable early outcomes than Western patients. However, outcomes of them need to be further looked into for a longer time.

BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR) is an independent prognostic marker in solid and hematological cancers. While the derived NLR (dNLR) was shown to be non-inferior to the NLR in large cohorts of patients with different cancer types, it has not been validated as a prognostic marker for multiple myeloma (MM) to date. METHODS: Between May 22, 2011 and May 29, 2014, 176 patients with MM from 38 centers who were ineligible for autologous stem cell transplantation were analyzed. The dNLR was calculated using complete blood count differential data. The optimal dNLR cut-off value according to receiver operating characteristic analysis of overall survival (OS) was 1.51. All patients were treated with melphalan and prednisone combined with bortezomib. RESULTS: The complete response rate was lower in the high dNLR group compared to the low dNLR group (7 vs. 26.1%, respectively; p = 0.0148); the corresponding 2-year OS rates were 72.2 and 84.7%, respectively (p = 0.0354). A high dNLR was an independent poor prognostic factor for OS (hazard ratio 2.217, 95% CI 1.015-4.842; p = 0.0458). CONCLUSION: The dNLR is a readily available and cheaply obtained parameter in clinical studies, and shows considerable potential as a new prognostic marker for transplantation-ineligible patients with MM.

AIMS: SB4 has been developed as a biosimilar of etanercept. The primary objective of the present study was to demonstrate the pharmacokinetic (PK) equivalence between SB4 and European Union -sourced etanercept (EU-ETN), SB4 and United States-sourced etanercept (US-ETN), and EU-ETN and US-ETN. The safety and immunogenicity were also compared between the treatments. METHODS: This was a single-blind, three-part, crossover study in 138 healthy male subjects. In each part, 46 subjects were randomized at a 1:1 ratio to receive a single 50 mg subcutaneous dose of the treatments (part A: SB4 or EU-ETN; part B: SB4 or US-ETN; and part C: EU-ETN or US-ETN) in period 1, followed by the crossover treatment in period 2 according to their assigned sequences. PK equivalence between the treatments was determined using the standard equivalence margin of 80-125%. RESULTS: The geometric least squares means ratios of AUCinf , AUClast and Cmax were 99.04%, 98.62% and 103.71% (part A: SB4 vs. EU-ETN); 101.09%, 100.96% and 104.36% (part B: SB4 vs. US-ETN); and 100.51%, 101.27% and 103.29% (part C: EU-ETN vs. US-ETN), respectively, and the corresponding 90% confidence intervals were completely contained within the limits of 80-125 %. The incidence of treatment-emergent adverse events was comparable, and the incidence of the antidrug antibodies was lower in SB4 compared with the reference products. CONCLUSIONS: The present study demonstrated PK equivalence between SB4 and EU-ETN, SB4 and US-ETN, and EU-ETN and US-ETN in healthy male subjects. SB4 was well tolerated, with a lower immunogenicity profile and similar safety profile compared with those of the reference products.

BACKGROUND: Genome-wide association studies have identified many genetic loci associated with blood pressure (BP). Genetic effects on BP can be altered by environmental exposures via multiple biological pathways. Especially, obesity is one of important environmental risk factors that can have considerable effect on BP and it may interact with genetic factors. Given that, we aimed to test whether genetic factors and obesity may jointly influence BP. METHODS: We performed meta-analyses of genome-wide association data for systolic blood pressure (SBP) and diastolic blood pressure (DBP) that included analyses of interaction between single nucleotide polymorphisms (SNPs) and the obesity-related anthropometric measures, body mass index (BMI), height, weight, and waist/hip ratio (WHR) in East-Asians (n = 12,030). RESULTS: We identified that rs13390641 on 2q12.1 demonstrated significant association with SBP when the interaction between SNPs and BMI was considered (P < 5 × 10 -8). The gene located nearest to rs13390641, TMEM182, encodes transmembrane protein 182. In stratified analyses, the effect of rs13390641 on BP was much stronger in obese individuals (BMI ≥ 30) than non-obese individuals and the effect of BMI on BP was strongest in individuals with the homozygous A allele of rs13390641. CONCLUSIONS: Our analyses that included interactions between SNPs and environmental factors identified a genetic variant associated with BP that was overlooked in standard analyses in which only genetic factors were included. This result also revealed a potential mechanism that integrates genetic factors and obesity related traits in the development of high BP.

BACKGROUND: Osteoporotic fracture (OF) as a clinical endpoint is a major complication of osteoporosis. To screen for OF susceptibility genes, we performed a genome-wide association study and carried out de novo replication analysis of an East Asian population. METHODS: Association was tested using a logistic regression analysis. A meta-analysis was performed on the combined results using effect size and standard errors estimated for each study. RESULTS: In a combined meta-analysis of a discovery cohort (288 cases and 1139 controls), three hospital based sets in replication stage I (462 cases and 1745 controls), and an independent ethnic group in replication stage II (369 cases and 560 for controls), we identified a new locus associated with OF (rs784288 in the MECOM gene) that showed genome-wide significance (p=3.59×10(-8); OR 1.39). RNA interference revealed that a MECOM knockdown suppresses osteoclastogenesis. CONCLUSIONS: Our findings provide new insights into the genetic architecture underlying OF in East Asians.

Various analytical approaches have been suggested for the characterization of rare variants. One main approach is to collapse the genetic information of rare variants in a region and to construct an overall test statistic. Here, we proposed a new approach based on collapsed genotype scores. By utilizing the information of the association signal that is ignored in collapsing methods, i.e. the configuration of rare alleles, we constructed a more powerful test and compared it with existing rare-variant approaches. With extensive simulation studies, we showed that our method performs better than existing approaches, and we applied our method to a sequencing study of nonsyndromic cleft lip illustrating the practical advantages of the proposed method.

This study aimed to identify underlying demographic and clinical characteristics among individuals who had previously attempted suicide, utilizing the comprehensive Health Insurance Review and Assessment Service (HIRA) database. Data of patients aged 18 and above who had attempted suicide between January 1 and December 31, 2014, recorded in HIRA, were extracted. The index date was identified when a suicide attempt was made within the year 2014. The medical history of the three years before the index date and seven years of follow-up data after the index date were analyzed. Kaplan-Meier estimate was used to infer reattempt of the suicide attempters, and Cox-proportional hazard analysis was used to investigate risk factors associated with suicide reattempts. A total of 17,026 suicide attempters were identified, of which 1,853 (10.9%) reattempted suicide; 4,925 (28.9%) patients had been diagnosed with depressive disorder. Of the reattempters, 391 (21.1%) demonstrated a history of suicide attempts in the three years before the index date, and the mean number of prior attempts was higher compared to that of the non-reattempters (1.7 vs.1.3, p-value < 0.01). Prior psychiatric medication, polypharmacy, and an increase in the number of psychotropics were associated with suicide reattempt in overall suicide attempters. (Hazard ratio (HR) = 3.20, 95% confidence interval [CI] = 2.56-4.00; HR = 2.42, 95% CI = 1.87-3.14; HR = 19.66, 95% CI = 15.22-25.39 respectively). The risk of reattempt decreased in individuals receiving antidepressant prescriptions compared to those unmedicated, showing a reduction of 78% when prescribed by non-psychiatrists and 89% when prescribed by psychiatrists. Similar risk factors for suicide reattempts were observed in the depressive disorder subgroup, but the median time to reattempt was shorter (556.5 days) for this group compared to that for the overall attempters (578 days). Various risk factors including demographics, clinical characteristics, and medications should be considered to prevent suicide reattempts among suicide attempters, and patients with depressive disorder should be monitored more closely.

BACKGROUND: This study investigated the safety and effectiveness of ustekinumab (UST) in Korean patients with Crohn's disease (CD). METHODS: Adult patients with CD treated with UST were prospectively enrolled in the K-STAR (Post-MarKeting Surveillance for Crohn's Disease patients treated with STelARa) study between April 2018 and April 2022. Both the clinical effectiveness and adverse effects of UST therapy were analyzed. Missing data were handled using nonresponder imputation (ClinicalTrials.gov Identifier: NCT03942120). RESULTS: Of the 464 patients enrolled from 44 hospitals across Korea, 457 and 428 patients (Crohn's disease activity indexâ ≥150) were included in the safety analysis and effectiveness analysis sets, respectively. At weeks 16 to 20 after initiating UST, clinical response, clinical remission, and corticosteroid-free remission rates were 75.0% (321 of 428), 64.0% (274 of 428), and 61.9% (265 of 428), respectively. At week 52 to 66, clinical response, clinical remission, and corticosteroid-free remission rates were 62.4% (267 of 428), 52.6% (225 of 428), and 50.0% (214 of 428), respectively. Combined effectiveness (clinical responseâ +â biochemical response) was achieved in 40.0% (171 of 428) and 41.6% (178 of 428) at week 16 to 20 and week 52 to 66, respectively. Biologic-naïve patients exhibited significantly higher rates of combined effectiveness than biologic-experienced patients (50.3% vs 30.7% at week 16-20, Pâ <â .001; 47.7% vs 36.0% at week 52-66, Pâ =â .014). No additional benefits were observed with the concomitant use of immunomodulators. Ileal location was independently associated with a higher probability of clinical remission compared with colonic or ileocolonic location at week 52 to 66. Adverse and serious adverse events were observed in 28.2% (129 of 457) and 12.7% (58 of 457), respectively, with no new safety signal associated with UST treatment. CONCLUSIONS: Ustekinumab was well-tolerated, effective, and safe as induction and maintenance therapy for CD in Korea.
Ustekinumab was well-tolerated and safe for Koran patients with Crohn's disease with no new safety signal as induction and maintenance therapy. Biologic-naïve patients exhibited better effectiveness outcomes, whereas combination therapy with immunomodulators was not superior to ustekinumab monotherapy.
RESUMEN
Background/Aims: To date, there is no prospective study that specifically investigated the efficacy of infliximab in intestinal Behçet's disease (BD). This study evaluated the efficacy of infliximab in patients with moderate-to-severe active intestinal BD that are refractory to conventional therapies. Methods: This phase 3, interventional, open-label, single-arm study evaluated clinical outcomes of infliximab treatment in patients with moderate-to-severe intestinal BD. The coprimary endpoints were clinical response, decrease in disease activity index for intestinal BD (DAIBD) score ≥20 from weeks 0 to 8 for the induction therapy and week 32 for the maintenance therapy. Results: A total of 33 patients entered the induction therapy and were treated with infliximab 5 mg/kg intravenously at weeks 0, 2, and 6. The mean DAIBD score changed from 90.8±40.1 at week 0 to 40.3±36.4 at week 8, with a significant mean change of 50.5±36.4 (95% confidence interval, 37.5 to 63.4; p<0.001). Thirty-one (93.9%) continued to receive 5 mg/kg infliximab every 8 weeks during the maintenance therapy. The mean change in the DAIBD score after the maintenance therapy was statistically significant (61.5±38.5; 95% confidence interval, 46.0 to 77.1; p<0.001, from weeks 0 to 32). The proportion of patients who maintained a clinical response was 92.3% at week 32. No severe adverse reactions occurred during the induction and maintenance therapies. Conclusions: This study provided evidence that infliximab 5 mg/kg induction and maintenance therapies are efficacious and well-tolerated in patients with moderate-to-severe active intestinal BD. (ClinicalTrials.gov identifier: NCT02505568).

Background/Aims: Golimumab has been used for patients with ulcerative colitis (UC) since 2013. However, there is limited data on the effectiveness and safety of the real-world use of golimumab in Asian patients. Methods: This was a multicenter, prospective, observational study. We enrolled patients with moderate-to-severe UC who were administered subcutaneous golimumab at 46 medical centers between May 2014 and November 2019. The primary outcome was the effectiveness and safety of golimumab at week 22. Clinical outcomes and adverse events were assessed according to partial Mayo score at weeks 0, 2, 6, 14, and 22. Results: A total of 130 patients were included (mean age: 45.7±16.0 years). The clinical response/ remission rates at weeks 2, 6, 14, and 22 were 40.4%/22.9%, 56.0%/35.8%, 70.6%/49.5%, and 67.9%/48.6%, respectively. Based on full Mayo score at week 14, clinical response and remission rates were 84.2% and 39.5%, respectively. Mucosal healing rate was 65.8%. In multivariate analysis with logistic regression, longer disease duration was significantly associated with a higher clinical response rate (adjusted odds ratio [aOR], 1.136; 95% confidence interval [CI], 1.006 to 1.282; p=0.040 at week 6; aOR, 1.256; 95% CI, 1.049 to 1.503; p=0.013 at week 22). A higher baseline Mayo endoscopic subscore was significantly associated with a lower clinical response rate at week 6 (aOR, 0.248; 95% CI, 0.089 to 0.692; p=0.008). The incidence of adverse drug reactions was 4.6% (6/130, nine events). No serious unexpected adverse drug reactions or deaths were reported. Conclusions: Golimumab was effective and safe as an induction and maintenance treatment for Korean patients with moderate-to-severe UC.

Background/Aims: Improving quality of life has been gaining importance in ulcerative colitis (UC) management. The aim of this study was to investigate changes in health-related quality of life (HRQL) and related factors in patients with moderate-to-severe UC. Methods: A multicenter, hospital-based, prospective study was performed using a Moderate-to-Severe Ulcerative Colitis Cohort in Korea (the MOSAIK). Changes in HRQL, evaluated using the 12-Item Short Form Health Survey (SF-12) and Inflammatory Bowel Disease Questionnaire (IBDQ), were analyzed at the time of diagnosis and 1 year later. Results: In a sample of 276 patients, the mean age was 38.4 years, and the majority of patients were male (59.8%). HRQL tended to increase in both the IBDQ and SF-12 1 year after diagnosis. A higher partial Mayo score was significantly related to poorer HRQL on the IBDQ and SF-12 in a linear mixed model (p<0.01). Inflammatory markers such as C-reactive protein (CRP) or erythrocyte sedimentation rate also showed a negative correlation on HRQL (p<0.05). Patients whose IBDQ score improved by 16 or more (71.2%) in 1 year were younger, tended to be nonsmokers, and had a lower partial Mayo score and CRP than those whose IBDQ score did not. There was no significant association between HRQL and disease extent, treatments at diagnosis, or the highest treatment step during the 1-year period. Conclusions: Optimally controlled disease status improves HRQL in patients with moderate-to-severe UC. The partial Mayo score and inflammatory markers may be potential indicators reflecting the influence of UC on patient`s daily lives.

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.
RESUMEN
INTRODUCTION: Golimumab is a human monoclonal antibody that inhibits tumor necrosis factor-α (TNF-α). Inhibition of TNF-α by golimumab inhibits the inflammatory response, thereby modulating the immune response in immune-mediated inflammatory diseases. Although the efficacy of golimumab has been demonstrated in randomized controlled trials (RCTs), various patient populations, such as those at high risk of infection, including those with latent tuberculosis and various comorbidities, or on co-administered medications, were excluded from the RCTs. Therefore, safety cannot be sufficiently evaluated by RCTs in the patient group with heterogenous characteristics. The aim of this study was to assess the safety and effectiveness of golimumab in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondyloarthritis (AS) in a real-world setting in Korea. METHODS: We conducted an open-label, prospective, non-interventional study as post-marketing surveillance. Safety was evaluated by collecting and recording adverse events, and effectiveness was evaluated by assessing disease activity using DAS28-CRP, DAS28-ESR, ACR20, and ASAS20 outcome measures. Multiple logistic regression was performed to identify factors associated with the incidence of adverse events, and changes in disease activity scores from baseline were analyzed using the Wilcoxon signed-rank test. RESULTS: A total 673 patients were enrolled, of whom 621 were included in the safety analysis. During the study, 97 adverse drug reactions (ADRs) were reported in 62 patients (10.0%). The most frequently reported ADRs were related to infection, including nasopharyngitis (0.8%), upper respiratory tract infection (0.6%), and herpes zoster (0.5%). The mean (± standard deviation) changes from baseline in global disease activity at weeks 12 and 24 were - 3.37 ± 2.529 and - 3.68 ± 2.404, respectively, with statistical significance. In those patients with RA, 72.5 and 47.0% of individuals had a good response based on DAS28-CRP and DAS28-ESR outcomes at week 24. At week 24, 71.4% of patients with PsA had an ACR20 response and 72.9% of patients with AS had an ASAS20 response. CONCLUSION: In the real-world setting, golimumab was safe and effective in Korean patients with RA, PsA, and AS.
RESUMEN
We aimed to evaluate the safety and effectiveness of darunavir (DRV) in the treatment of human immunodeficiency virus-1 (HIV-1) infection in Korea. From October 29, 2010, 225 eligible patients with HIV-1 infection receiving DRV were enrolled. DRV was administered with other antiretroviral agents, and followed for 24 weeks. The primary objective was safety evaluation, and effectiveness was assessed by viral load and CD4 T cell counts after 12 weeks and 24 weeks. Adverse drug reactions occurred in 18 patients (9.2%); diarrhea was the most common. Viral load was controlled (<400 copies/mL) in 90.9% of patients. CD4 T cell counts were increased 45.0/mm³ significantly at Week 12 (P = 0.0002), and 70.5/mm³ at Week 24 (P <0.0001). DRV safety and effectiveness was consistent with previous studies.
RESUMEN
Postmarketing surveillance is conducted to establish drug safety and effectiveness under real-world practice. We aimed to validate the effectiveness and safety of ustekinumab in the treatment of adult Korean patients with plaque psoriasis under real-world practice. This was a prospective, observational, and multi-center study. Subjects aged 18 years or older who were treated with ustekinumab for plaque psoriasis were enrolled. We enrolled 977 patients; 654 (66.9%) were men, with mean body surface area (BSA, ± standard deviation) of 27.0 ± 18.3% and mean psoriasis area severity index (PASI) score of 18.1 ± 9.7. The effectiveness analysis was performed in 581 patients who had at least one follow-up assessment and met treatment criteria per local label and reimbursement guidelines. Of these patients, 287 had effectiveness data for visit 6 at 53.7 ± 2.1 weeks. At visit 6, 91.6% (263/287), 51.2% (147/287), and 9.4% (27/287) patients achieved PASI 75, 90, and 100 responses, respectively. Adverse events (AEs) occurred in 112 of the 977 (11.5%) patients with an incidence rate of 21.5 per 100 patient-years (PYs). Serious AEs occurred in eight (0.8%) patients with an incidence rate of 1.2 per 100 PYs. The estimated 1-year drug survival rate was 87.7%. The multiple logistic regression analysis showed that higher baseline PASI score and no prior biologic exposure were significant predictors for PASI 90 response at visit 6. Ustekinumab was effective and safe, and displayed a high survival rate in the treatment of adult Korean patients with plaque psoriasis in real-world practice.

Background/Aims: Limited data are available regarding psychosocial distress at the time of diagnosis of ulcerative colitis (UC). We investigated the psychosocial burden and factors related to poor health-related quality of life (HRQL) among patients newly diagnosed with moderate-to-severe UC who were affiliated with the nationwide prospective cohort study. Methods: Within the first 4 weeks of UC diagnosis, all patients were assessed using the Hospital Anxiety and Depression Scale (HADS), Work Productivity and Activity Impairment questionnaire, Inflammatory Bowel Disease Questionnaire (IBDQ), and 12-Item Short Form (SF-12) health survey. A multiple linear regression model was used to identify factors associated with HRQL. Results: Between August 2014 and February 2017, 355 patients completed questionnaires. Significant mood disorders requiring psychological interventions, defined by a HADS score ≥11, were identified in 16.7% (anxiety) and 20.6% (depression) of patients. Patients with severe disease were more likely to have presenteeism, loss of work productivity, and activity loss than those with moderate disease (all p<0.05). Significant mood disorders had the strongest negative relationship with total IBDQ score, which indicates disease-specific HRQL (ß coefficient: -22.1 for depression and -40.0 for anxiety, p<0.001). The scores of all SF-12 dimensions, which indicate general HRQL, were remarkably decreased in the study population compared indirectly with previously reported scores in the general population. The Mayo score, C-reactive protein level, and white blood cell count showed significant negative associations with the IBDQ score (p<0.05). Conclusions: Psychosocial screening and timely interventions should be incorporated into the initial care of patients newly diagnosed with UC.

BACKGROUND: Psoriasis and psoriatic arthritis (PsA) are included in the group of immune-mediated inflammatory diseases (IMIDs) caused by systemic inflammation; however, indicators for monitoring inflammatory activity in patients with psoriasis, such as the Psoriasis Area and Severity Index (PASI), are limited. OBJECTIVE: To determine whether the Psoriatic Arthritis Screening and Evaluation (PASE) questionnaire can be used to monitor disease activity in patients with psoriasis. METHODS: This was a multicenter, noninterventional, cross-sectional study. Demographic factors and PASI and PASE scores were collected to investigate associations between each. RESULTS: PASE data were available for 1,255 patients, of whom 498 (39.7%) had a score of ≥37. Compared with the group with PASE score <37, the group with score ≥37 had a higher proportion of women (34.9% vs. 48.8%, p<0.0001), older mean age at diagnosis (36.4 vs. 41.7 years, p<0.0001), more severe disease activity using PASI and body surface area measures (p=0.0021 and p=0.0008, respectively), and higher mean body mass index (23.7 vs. 24.1, p=0.0411). In a multiple linear regression model, PASE score was positively associated with cutaneous disease activity (p<0.0001). CONCLUSION: After risk-adjustment, PASE was positively associated with PASI, which suggests that PASE can be sensitive to disease activity. Since psoriasis is regarded as one of the IMIDs, PASE may be utilized as a tool not only to screen PsA but also to monitor disease activity.
RESUMEN
While ustekinumab has been widely used as an effective biologic for the treatment of chronic plaque psoriasis, no prospective studies have specifically investigated the clinical factors that may influence treatment outcomes with ustekinumab. This post-hoc analysis aimed to identify specific clinical factors that may influence treatment outcomes with ustekinumab in psoriasis patients. In the MARCOPOLO study, 102 Korean patients with moderate to severe psoriasis were analyzed to assess the influence of baseline characteristics as clinical factors on clinical response (improvement in Psoriasis Area and Severity Index by ≥75%/90% [PASI75/PASI90]) to ustekinumab. In addition, differences in PASI75 and PASI90 responses between the responder group and non-responders were evaluated at weeks 28 and 52. Multiple logistic regression analysis was used to determine adjusted clinical factors predicting treatment outcomes among patient characteristics. At week 28, there was a significant difference in PASI75/PASI90 response based on prior biologic experience, although the difference did not persist at week 52. In addition, after adjusting for the effects of relevant clinical factors, biologic experience was significantly associated with less PASI75 (odds ratio [OR] = 0.14, P = 0.001) and PASI90 (OR = 0.22, P = 0.036) responses at week 28. The presence of comorbidities was higher among non-responders than among PASI75/PASI90 responders at both weeks 28 and 52, but was not statistically significant. Previous biologic use was the only clinical factor predicting less response at week 28, although it did not influence the clinical response after week 52. Further studies are warranted to investigate the association between presence of comorbidities and clinical response.

BACKGROUND: Psoriasis is an immune-mediated, chronic inflammatory disease affecting multiple aspects of patients' lives. Its epidemiology varies regionally; however, nationwide epidemiologic data on psoriasis depicting profile of Korean patients has not been available to date. OBJECTIVE: To understand nationwide epidemiologic characteristics and clinical features of adult patients with psoriasis visited university hospitals in Korea. METHODS: This multicenter, non-interventional, cross-sectional study recruited 1,278 adult patients with psoriasis across 25 centers in Korea in 2013. Various clinical data including PASI, BSA, DLQI, SF-36 and PASE were collected. RESULTS: A total of 1,260 patients completed the study (male:female=1.47:1). The mean age was 47.0 years with a distribution mostly in the 50s (24.9%). Early onset (<40 years) of psoriasis accounted for 53.9% of patients. The mean disease duration was 109.2 months; mean body mass index was 23.9 kg/m2; and 12.7% of patients had a family history of psoriasis. Plaque and guttate types of psoriasis accounted for 85.8% and 8.4%, respectively. Patients with PASI ≥10 accounted for 24.9%; patients with body surface area ≥10 were 45.9%. Patients with DLQI ≥6 accounted for 78.8%. Between PASI <10 and PASI ≥10 groups, significant difference was noted in age at diagnosis, disease duration, blood pressure, waist circumference of female, and treatment experiences with phototherapy, systemic agents, and biologics. CONCLUSION: This was the first nationwide epidemiologic study of patients with psoriasis in Korea and provides an overview of the epidemiologic characteristics and clinical profiles of this patient population.
