Pham NTU, Nguyen TV, Nguyen HT. HLA-Cw6 increases the risk of psoriasis and early onset before twenty-seven years of age among the Vietnamese population. Dermatol Reports 2024; 16:9854. [PMID: 38957641 PMCID: PMC11216135 DOI: 10.4081/dr.2023.9854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 10/05/2023] [Indexed: 07/04/2024] Open
Abstract
Psoriasis is a chronic inflammatory skin disease that affects people all over the world. It is linked to the HLA-Cw6 allele, which is more common in Caucasians than in Asians and varies across ethnic groups. We investigated the association between the disease severity and the onset age of HLA-Cw6 prevalence in Vietnamese psoriasis patients. In 121 psoriasis patients and 30 healthy controls, we looked at the relationship between HLA-Cw6 and clinical features. We found that patients with psoriasis had significantly higher levels of HLA-Cw6 (64.5%) than controls (26.7%) (p=0.0001), with an odds ratio of 4.98 (2.04-12.15). Positive HLA-Cw6 patients had a significantly lower mean age of psoriasis onset than negative HLA-Cw6 patients. Patients with mild psoriasis (100%) were more likely to have the AA genotype, while patients with moderate to severe psoriasis (47.2% and 59.0%, respectively) and those with high PASI scores (55.1% and 54.1%, respectively) were more likely to have the TA genotype. Thus, HLA-Cw6 is a major genetic risk factor for psoriasis in Vietnamese patients, especially early-onset cases. Variations in HLA-Cw6 genotypes also affect disease severity.

Epidemiological analysis of the patients with psoriasis in Asian countries and region using the same clinical case cards between 2020 and 2022. J Dermatol 2024; 51:567-583. [PMID: 38345285 DOI: 10.1111/1346-8138.17132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 12/21/2023] [Accepted: 01/11/2024] [Indexed: 02/28/2024]
Abstract
Although many epidemiological surveys for patients with psoriasis have been reported based on individual countries or facilities, there has been no study encompassing the major countries or the region in Asia. The Asian Society for Psoriasis (ASP) has been conducting an epidemiological study across various Asian countries and regions to elucidate the and compare the epidemiology of psoriasis. A total of 1948 cases were analyzed, with 938 cases from Japan, 530 cases from China, 325 cases from Korea, 141 cases from Chinese Taipei, and 14 cases from Thailand, all of which were enrolled between 2020 and 2022. In the Asian region total, the male-female ratio was 1.87:1 and the peak age at disease onset was 20-29 years. The proportion of psoriasis vulgaris (PsV), psoriatic arthritis (PsA), and pustular psoriasis (PP) was 80.1%, 17.7%, and 2.2%, respectively, and PsA was more commonly associated with nail symptoms than psoriasis vulgaris (PsV). Of the patients, 13% had a familial history of psoriasis and the most frequently affected family member was the father. Regarding treatment, 78.3% of the patients received topical medications, 9.0% underwent phototherapy, 34.0% received oral medications, and 36.1% were treated with biological agents. This study provided valuable information on the epidemiology and treatment of psoriasis using the registry data collected with the common reporting form in the same period in major Asian countries and regions. Male predominance is a distinctive feature of psoriasis in Asia. This epidemiological data registry in the ASP will continue afterwards.

Unlocking the role of the B7-H4 polymorphism in psoriasis: Insights into methotrexate treatment outcomes: A prospective cohort study. Immunology 2024; 171:104-116. [PMID: 37814391 DOI: 10.1111/imm.13704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 09/28/2023] [Indexed: 10/11/2023] Open
Abstract
B7-H4 is a recently discovered member of B7 family that negatively regulates T-cell immunity, specifically Th1 and Th17 cell responses. However, its role in the pathogenesis of psoriasis has yet to be determined. This study aims to investigate the effect of B7-H4 polymorphism on the efficacy of methotrexate (MTX) and its mechanism in psoriasis. Four single nucleotide polymorphisms of B7-H4 were genotyped in 310 psoriatic patients who received 12-week MTX. The protein expression of B7-H4 in platelets was characterized using immunofluorescence staining, confocal laser scanning microscopy, and flow cytometry techniques. We found that GG genotype carriers of B7-H4 rs1935780 had a lower Psoriasis Area and Severity Index (PASI) 75 response rate and higher weight (p = 0.0245) and body mass index (p = 0.0185) than AA and AG genotype carriers. Multiple regression analysis showed that the PASI score at baseline (p = 0.01) and age at disease onset (p = 0.003) were positively correlated with PASI 75 response rate, while weight (p = 0.005) and the rs1935780 genotype (p = 0.003) were negatively associated with PASI 75 response rate. B7-H4 was expressed in the platelet plasma membrane and cytoplasm. Furthermore, the expression of B7-H4 protein in platelets was lower in good responders than in non-responders and was upregulated considerably after 12-week MTX or in vitro MTX stimulation in good responders. Collectively, these results demonstrate that psoriatic patients with GG genotype of B7-H4 rs1935780 had a poorer response to MTX. Low expression of B7-H4 protein in platelets correlated with better clinical outcomes of MTX in psoriasis.

Five-year Maintenance of Clinical Response and Consistent Safety Profile for Guselkumab in Asian patients with Psoriasis from VOYAGE 1 and VOYAGE 2. Dermatol Ther (Heidelb) 2023; 13:2721-2737. [PMID: 37750995 PMCID: PMC10613179 DOI: 10.1007/s13555-023-01026-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 02/23/2023] [Indexed: 09/27/2023] Open
Abstract
INTRODUCTION Guselkumab is a human monoclonal antibody against IL-23 used in the treatment of moderate-to-severe psoriasis. This post-hoc analysis evaluated the efficacy and safety of guselkumab in the Asian subpopulation of VOYAGE 1 and VOYAGE 2 through 5 years. METHODS The proportions of guselkumab-treated Asian patients (VOYAGE 1 and 2) achieving Psoriasis Area and Severity Index (PASI) 90 and PASI 100, Investigator's Global Assessment (IGA) scores of 0/1 and 0, and Dermatology Life Quality Index (DLQI) scores of 0/1 (week 100 through week 252) were assessed. Non-responders were patients who met the treatment failure rules. Efficacy endpoints were analyzed using the as-observed methodology (no missing data imputation) for both studies and using non-responder imputation (for patients with any missing data) in VOYAGE 1. Safety outcomes were based on pooled data through week 252. RESULTS Response rates through week 252 for 199 Asian patients in the guselkumab group in VOYAGE 1 and VOYAGE 2, respectively, were 76.8% and 80.6% (PASI 90), 26.8% and 38.7% (PASI 100), 64.3% and 87.1% (IGA 0/1), and 26.8% and 45.2% (IGA 0). DLQI (0/1) at week 252 was achieved by 52.7% of patients in VOYAGE 1 and 61.3% in VOYAGE 2, while DLQI (0) at week 252 was achieved by 32.7% of patients in VOYAGE 1 and 40.3% in VOYAGE 2. The safety profile was similar to the global population and remained consistent through 5 years. Asian patients were followed for a total of 814 patient-years (PY). Over 85% of the guselkumab-treated patients continued treatment through week 264. The rate of serious adverse events (AEs) at week 252 was 3.07/100 PY. Rates of AEs of interest were low: serious infections, 0.74/100 PY; nonmelanoma skin cancer (NMSC), no patients; malignancies other than NMSC, 0.12/100 PY; and no major adverse cardiovascular events (MACE). CONCLUSION These analyses confirm a continuous response over 5 years, indicating that guselkumab shows therapeutic longevity in Asian patients requiring long-term treatment for moderate-to-severe psoriasis. TRIAL REGISTRATION ClinicalTrials.gov identifiers: VOYAGE 1 [NCT02207231] and VOYAGE 2 [NCT02207244].

J Dermatol 2023; 50:1180-1189. [PMID: 37341137 DOI: 10.1111/1346-8138.16865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 03/27/2023] [Accepted: 06/04/2023] [Indexed: 06/22/2023]
Abstract
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.

Arch Dermatol Res 2022; 315:1241-1247. [PMID: 36513862 DOI: 10.1007/s00403-022-02498-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 10/31/2022] [Accepted: 11/28/2022] [Indexed: 12/15/2022]
Abstract
MTX in genetically distinctive Chinese psoriatic patients remains less explored. The present study aimed to determine the impact of HLA-Cw*06 on MTX response in a Chinese psoriasis patient population. A total of 204 patients with psoriasis were enrolled in this study. Clinical data and DNA samples from all patients were collected. The allele of HLA-Cw*06 genotyping was detected using direct Sanger sequencing. This study enrolled 204 patients with psoriasis, including 47 (23.04%) psoriatic arthritis patients, 157 (76.96%) patients free of psoriatic arthritis. Overall, 110 (53.92%) of all patients carried the HLA-Cw*06 allele. This frequency in patients with arthritis-free psoriasis was higher than that in those with psoriatic arthritis (58.59 vs. 38.30%, P = 0.014). After 8 weeks of MTX treatment, the arthritis-free psoriasis patients, who tested positive for the HLA-Cw*06 allele, showed significant improvement compared to those who tested negative (For PASI50, 78.57 vs. 55.22%, P = 0.02, and for PASI75, 51.11 vs. 34.33%, P = 0.036). The psoriatic arthritis-free patients who carried the HLA-Cw*06 allele in combination with the ABCB1 rs1045642 CC genotype showed the highest improvement. A regression model containing HLA-Cw*06, rs1045642T > C, and initial PASI scores was used to construct the efficacy prediction model of MTX, which yielded AUC values of 73.2 and 75.6% for PASI50 and PASI75 to MTX, respectively, in arthritis-free psoriasis patients. The HLA-Cw*06 allele is associated with optimal response to MTX treatment in arthritis-free Chinese psoriasis patients. When combined with clinical indicators, the polymorphism explained more than 75% of the individual efficacy differences.

Abstract
Skin of color (SOC) populations include those who identify as Black/African, Hispanic/Latinx, Asian/Pacific Islander, American Indian/Native Alaskan, Indigenous Australian, Middle Eastern, biracial/multiracial, or non-White; this list is far from exhaustive and may vary between and within cultures. Recent genetic and immunological studies have suggested that cutaneous inflammatory disorders (atopic dermatitis, psoriasis, and hidradenitis suppurativa) and malignancies (melanoma, basal cell carcinoma, and cutaneous T-cell lymphoma) may have variations in their immunophenotype among SOC. Additionally, there is growing recognition of the substantial role social determinants of health play in driving health inequalities in SOC communities. It is critically important to understand that social determinants of health often play a larger role than biologic or genetic factors attributed to "race" in health care outcomes. Herein, we describe the structural, genetic, and immunological variations and the potential implications of these variations in populations with SOC. This article underscores the importance of increasing the number of large, robust genetic studies of cutaneous disorders in SOC to create more targeted, effective therapies for this often underserved and understudied population. Part II of this CME will highlight the clinical differences in the phenotypic presentation of and the health disparities associated with the aforementioned cutaneous disorders in SOC.

Imputation of the major histocompatibility complex region identifies major independent variants associated with bullous pemphigoid and dermatomyositis in Han Chinese. J Dermatol 2022; 49:998-1004. [PMID: 35751838 DOI: 10.1111/1346-8138.16499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 04/29/2022] [Accepted: 06/05/2022] [Indexed: 11/27/2022]
Abstract
As autoimmune skin diseases, both bullous pemphigoid (BP) and dermatomyositis (DM) show significant associations with the major histocompatibility complex (MHC) region. In fact, the coexistence of BP and DM has been previously reported. Therefore, we hypothesized that there may be a potential genetic correlation between BP and DM. Based on data for 312 BP patients, 128 DM patients, and 6793 healthy control subjects, in the MHC region, we imputed single-nucleotide polymorphisms (SNP), insertions and deletions (INDEL), and copy number variations (CNV) using the 1KGP phase 3 dataset and amino acids (AA) and SNP using a Han-MHC reference database. An association study revealed the most significant SNP associated with BP, namely, rs580921 (p = 1.06E-08, odds ratio [OR] = 1.61, 95% confidence interval [CI] = 1.37-1.90), which is located in the C6orf10 gene, and the most significant classic human leukocyte antigen (HLA) allele associated with DM, namely, HLA-DPB1*1701 (p = 6.56E-10, OR = 3.61, 95% CI = 2.40-5.42). Further stepwise regression analyses with rs580921 identified a threonine at position 163 of the HLA-B gene as a new independent disease-associated AA, and HLA-DPB1*1701 indicated that no loci were significant. Three-dimensional ribbon models revealed that the HLA-B AA position 163 (p = 3.93E-07, OR = 1.64, 95% CI = 1.35-1.98) located in the α2 domain of the HLA-B molecule was involved in the process of specific antigen presentation. The calculations showed that there was no significant genetic correlation between BP and DM. Our study identified three significant loci in the MHC region, proving that the HLA region was significantly correlated with BP and DM separately. Our research highlights the key role of the MHC region in disease susceptibility.

Abstract
The identification of robust endotypes-disease subgroups of clinical relevance-is fundamental to stratified medicine. We hypothesized that HLA-C∗06:02 status, the major genetic determinant of psoriasis, defines a psoriasis endotype of clinical relevance. Using two United Kingdom-based cross-sectional datasets-an observational severe-psoriasis study (Biomarkers of Systemic Treatment Outcomes in Psoriasis; n = 3,767) and a large population-based bioresource (UK Biobank, including n = 5,519 individuals with psoriasis)-we compared demographic, environmental, and clinical variables of interest in HLA-C∗06:02-positive (one or two copies of the HLA-C∗06:02 allele) with those in HLA-C∗06:02‒negative (no copies) individuals of European ancestry. We used multivariable regression analyses to account for mediation effects established a priori. We confirm previous observations that HLA-C∗06:02-positive status is associated with earlier age of psoriasis onset and extend findings to reveal an association with disease expressivity in females (Biomarkers of Systemic Treatment Outcomes in Psoriasis: P = 2.7 × 10-14, UK Biobank: P = 1.0 × 10-8). We also show HLA-C∗06:02-negative status to be associated with characteristic clinical features (large plaque disease, OR for HLA-C∗06:02 = 0.73, P = 7.4 × 10-4; nail involvement, OR = 0.70, P = 2.4 × 10-6); higher central adiposity (Biomarkers of Systemic Treatment Outcomes in Psoriasis: waist circumference difference of 2.0 cm, P = 8.4 × 10-4; UK Biobank: waist circumference difference of 1.4 cm, P = 1.5 × 10-4), especially in women; and a higher prevalence of other cardiometabolic comorbidities. These findings extend the clinical phenotype delineated by HLA-C∗06:02 and highlight its potential as an important biomarker to consider in future multimarker stratified medicine approaches.

Transethnic analysis of psoriasis susceptibility in South Asians and Europeans enhances fine-mapping in the MHC and genomewide. HGG ADVANCES 2022; 3:100069.

Abstract
Because transethnic analysis may facilitate prioritization of causal genetic variants, we performed a genomewide association study (GWAS) of psoriasis in South Asians (SAS), consisting of 2,590 cases and 1,720 controls. Comparison with our existing European-origin (EUR) GWAS showed that effect sizes of known psoriasis signals were highly correlated in SAS and EUR (Spearman ρ = 0.78; p < 2 × 10-14). Transethnic meta-analysis identified two non-MHC psoriasis loci (1p36.22 and 1q24.2) not previously identified in EUR, which may have regulatory roles. For these two loci, the transethnic GWAS provided higher genetic resolution and reduced the number of potential causal variants compared to using the EUR sample alone. We then explored multiple strategies to develop reference panels for accurately imputing MHC genotypes in both SAS and EUR populations and conducted a fine-mapping of MHC psoriasis associations in SAS and the largest such effort for EUR. HLA-C*06 was the top-ranking MHC locus in both populations but was even more prominent in SAS based on odds ratio, disease liability, model fit and predictive power. Transethnic modeling also substantially boosted the probability that the HLA-C*06 protein variant is causal. Secondary MHC signals included coding variants of HLA-C and HLA-B, but also potential regulatory variants of these two genes as well as HLA-A and several HLA class II genes, with effects on both chromatin accessibility and gene expression. This study highlights the shared genetic basis of psoriasis in SAS and EUR populations and the value of transethnic meta-analysis for discovery and fine-mapping of susceptibility loci.

Abstract
Background The study of HLA classes I and II in Brazilian psoriasis patients may contribute to a better understanding of their association with the disease. Objective To describe HLA classes I and II of Brazilian patients with psoriasis, with or without arthritis, compare them to controls and correlate HLA markers with epidemiological and evolutional aspects of psoriasis. Methods A total of 55 patients with more than 5 years of psoriasis, with or without arthritis, answered a questionnaire on ethnic background and disease severity. A total of 134 bone marrow donors were controls. HLA class I and II genotyping was determined by PCR-SSP. Results Mean age was 42.4 years; 23 women and 32 men. HLA-B*57 was present in 23.6% patients and in 7.5% controls (p=0.00200, OR= 3.8381), and HLA-C*06 in 29.1% patients and in 16.4% controls (p= 0.04832, OR=2.0886). HLA-B*57 and HLA-C*18 were significantly present in patients with arthritis (p=0.00104, OR=6.6769 and p=0.00269, OR=16.50, respectively). HLA-B*57 was significantly present in patients with history of erythroderma (p=0.00548, OR= 5.1059), as was HLA-C*06 (p=0.02158, OR=3.0545). HLA-B*57 was also frequent in patients with history of hospital internment due to psoriasis (p= 0.00094, OR=7.8909) and in the ones with history of systemic treatment for psoriasis (p= 0.00011, OR= 5.3733). Haplotype HLA-A*02 B*57 C*06 DRB1*07DQB1*03 was the most common among the patients (p= 0.00069, OR= 3.528). Conclusion HLA-B*57 and HLA-C*06 were significantly increased in the patients indicating risk for psoriasis. HLA-B*57 remained high in patients with history of erythroderma, hospital internment, systemic treatment, and psoriatic arthritis, showing association with disease severity. HLA-C*18 was significantly high only in patients with psoriatic arthritis. HLA-B*57 and HLA-C*06 and haplotype HLA-A*02B*57Cw*06DRB1*07 DQB1*03 seen in this study were already described before, associated with psoriasis. HLA-Cw*18 was not described in other populations in association with psoriasis.

Abstract
Psoriasis is a chronic inflammatory skin condition with regional and ethnic differences in its prevalence and clinical manifestations. Human leukocyte antigen (HLA)-Cw6 is the disease allele conferring the greatest risk to psoriasis, but its prevalence is lower in Asian individuals. Recent studies have found associations between HLA-Cw1 and some Asian populations with psoriasis, especially Southern Chinese. HLA-Cw6 was associated with type I early-onset psoriasis, guttate psoriasis, Koebner phenomenon, and better response to methotrexate, interleukin (IL)-12/23, IL-17, and IL-23 targeting drugs. In contrast, HLA-Cw1 positivity has been associated with erythrodermic psoriasis, pustular psoriasis, and the axial type of psoriatic arthritis. Furthermore, HLA-Cw1 was more frequently associated with high-need patients who did not respond to conventional therapies. No known trigger factor nor autoantigen has been identified for HLA-Cw1 positivity. However, HLA-Cw1 has been linked to some viral agents. For example, cytotoxic T lymphocytes recognize multiple cytomegalovirus pp65-derived epitopes presented by HLA alleles, including HLA-C*01:02. In addition, cytomegalovirus can lead to severe exacerbation of psoriatic skin disease. The proposed interaction between viral infection, HLA-Cw1, and psoriasis is through the killer cell immunoglobulin-like receptors of natural killer cells. Given the diverse nature of psoriasis pathogenesis and the difference in HLA-Cw prevalence in different racial groups, more studies are needed to confirm the role of HLA-Cw1 in psoriasis.

Abstract
BACKGROUND Erythrodermic psoriasis (EP) is a rare variant of psoriasis that involves more complications and poorer biologic drug survival than plaque-type psoriasis vulgaris (PV). No prior study has explored human leukocyte antigen (HLA) or other genetic polymorphisms in patients with EP. OBJECTIVES Our objective was to describe the clinical features, comorbidities, and HLA polymorphisms among Chinese patients with EP. METHODS We enrolled consecutive patients with EP from our clinic, with EP defined as generalized confluent erythematous thin plaques covering at least 80% body surface area. Patients were categorized as having primary or secondary EP. Aggravating factors, comorbidities including psoriatic arthritis, family history of psoriasis, age of onset, and treatment history were also identified. Genetic studies were performed for HLA-C and HLA-DRB1, and the results were compared with those from a healthy population and patients with PV. RESULTS Of the 63 included patients, the male to female ratio was 2.71:1. Five (7.9%) patients had primary EP, and 58 (92.1%) had secondary EP. Genotyping of HLA-C and HLA-DRB1 was available in 61 and 58 subjects, respectively. HLA-C*0102 was the most frequent HLA-C allele (34.4%), followed by HLA-C*0702 (18.0%). The frequency of HLA-C*0602 allele (4.1%) was lower than in patients with plaque-type psoriasis (4.1 vs. 16.3%, corrected p value [Pc] = 0.02) and similar to that in the healthy population in Taiwan. The most frequent HLA-DRB1 allele was HLA-DRB1*0901 (20.7%), followed by HLA-DRB1*0803 (13.8%). An increased prevalence of psoriatic arthritis (61.9%) and higher male predominance were also noted in comparison with PV. CONCLUSIONS There are HLA differences in Chinese patients with EP compared with patients with PV. The incidence of psoriatic arthritis is also higher. The implications of the above findings await further investigation.

Abstract
INTRODUCTION Psoriasis is a systemic, chronic inflammatory disease that not only afflicts the skin but is also associated with cardiovascular disease and metabolic syndrome. The strongest susceptibility loci for the disease is within the human leukocyte antigen (HLA) complex, though specific HLA allelic associations vary between populations. OBJECTIVE Our objective was to investigate HLA associations with clinical phenotypes of psoriasis and metabolic syndrome in Chinese psoriasis cases. METHODS We conducted an observational case-control study in Singapore with a cohort of psoriasis cases consecutively recruited from an outpatient specialist dermatological center (n = 120) compared with 130 healthy controls. RESULTS Significant HLA associations with psoriasis were observed with HLA-A*02:07, B*46:01, C*01:02, and C*06:02. The three-locus haplotype of A*02:07-C*01:02-B*46:01 was also significant (odds ratio [OR] 3.07; p = 9.47 × 10-5). We also observed an association between nail psoriasis and HLA-A*02:07 carriers (OR 4.50; p = 0.002), whereas C*06:02 carriers were less prone to have nail involvement (OR 0.16; p = 0.004). HLA-A*02:07 was also identified as a possible risk allele for hypertension (OR 2.90; p < 0.05), and C*01:02 was a possible risk allele for dyslipidemia (OR 3.36; p < 0.05), both known to be common comorbidities in patients with psoriasis. CONCLUSION Our results demonstrate the growing importance of discerning population-specific clinical phenotypes and their association with certain HLA alleles in psoriasis.

Reich K, Song M, Li S, Jiang J, Youn SW, Tsai TF, Choe YB, Huang YH, Gordon KB. Consistent responses with guselkumab treatment in Asian and non-Asian patients with psoriasis: An analysis from VOYAGE 1 and VOYAGE 2. J Dermatol 2019; 46:1141-1152. [PMID: 31631377 DOI: 10.1111/1346-8138.15109] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Accepted: 09/09/2019] [Indexed: 01/05/2023]
Abstract
Guselkumab, an interleukin-23 blocker, was superior to placebo and adalimumab and well-tolerated in phase 3 psoriasis studies (VOYAGE 1 and VOYAGE 2). This analysis evaluated the consistency of response in the Asian subpopulation in VOYAGE 1 and VOYAGE 2. Study designs were identical through week 24; patients were randomized to guselkumab, placebo, or adalimumab. Investigator's Global Assessment (IGA), Psoriasis Area and Severity Index (PASI), safety, and pharmacokinetic and immunogenicity data from VOYAGE 1 and VOYAGE 2 were pooled and compared by race (Asian, n = 199; non-Asian, n = 1630). At week 16, treatment differences between guselkumab and placebo were 78.2 (95% confidence interval [CI], 66.9-89.6) and 76.4 (95% CI, 72.7-80.2) percentage points for IGA 0/1 (score of 0 or 1) and 70.1 (95% CI, 60.0-80.1) and 68.5 (95% CI, 64.9-72.2) percentage points for PASI 90 (≥90% improvement) in the Asian and non-Asian populations, respectively. Treatment differences between guselkumab and adalimumab were 31.1 (95% CI, 17.7-44.6) and 16.1 (95% CI, 11.2-21.0) percentage points for IGA 0/1 and 24.9 (95% CI, 9.4-40.5) and 23.2 (95% CI, 17.7-28.6) percentage points for PASI 90 in the Asian and non-Asian populations, respectively. Similar results were observed at week 24. Safety was generally similar between populations and among treatment groups. Median serum guselkumab concentrations over time were comparable between the populations. Comparable responses between the Asian and non-Asian populations in this analysis suggest that the overall efficacy, safety, and the resulting benefit/risk analyses from VOYAGE 1 and VOYAGE 2 are applicable to Asian populations.

Abstract
Background Correlation between severity of psoriasis and psoriatic arthritis (PsA) is inconsistent. Also, human leukocyte antigen (HLA)-Cw6 was found to be underrepresented in severe psoriasis who failed conventional systemic therapies, but the effect of HLA polymorphism on PsA severity needs to be confirmed. Objectives To describe the severity of psoriasis, demographic features and HLA polymorphism among Chinese patients with active peripheral type PsA who had inadequate response to conventional disease-modifying antirheumatic drugs. Methods We included all patients with PsA who had at least 3 tender and swollen peripheral joints despite at least two conventional non-biologic treatments in our clinic. Demographic results were compared with global pivotal studies of biologics for PsA. HLA-Cw and HLA-DRB1 genotyping was also analyzed. Results We identified 60 patients who met our inclusion criteria. The male to female ratio was 1.31:1. The majority of patients presented with psoriasis first (81.7%). The mean interval between psoriasis and PsA was 7.2 ± 8.1 years (mean ± SD). The baseline number of tender and swollen joints was 14.9 ± 10.7 and 11.3 ±10.2, respectively. In total, 41.7% subjects had more than 3% body surface area involvement of psoriasis. Genotyping of HLA-Cw and HLA-DRB1 was performed in 47 subjects. HLA-Cw*0702 was the most frequent allele (29.8%), followed by HLA-Cw*01 (26.6%). The frequency of HLA-Cw*0602 allele was similar to normal population. The most frequent HLA-DRB1 allele was HLA-DRB1*04 (20.2%), followed by HLA-DRB1*08 (16.0%). No cases carrying HLA-DRB1*13 were detected. Conclusions Compared with Western population, our patients had less psoriasis and PsA burden. The frequencies of HLA-Cw*06, HLA-Cw*12, and HLA-DRB1*07 were not increased. In contrast, HLA-Cw*0702 and HLA-DRB1*08 allele frequencies were increased compared with psoriasis patients and normal population in Taiwan. Future studies are still needed to characterize the demographic and genetic features of high need PsA patients.

Abstract
Psoriasis is a multifactorial disease with a strong genetic background. HLA-Cw6 is one of the most strongly associated psoriasis susceptibility alleles. It is repeatedly observed to affect disease course, phenotypic features, severity, comorbidities and treatment outcomes. To the best of our knowledge, the roles of HLA-Cw6 in psoriasis have not yet been thoroughly reviewed. The worldwide frequency of the HLA-Cw6 allele varies greatly, with it being generally higher in white people than in Asians. The allele is associated with type I early-onset psoriasis. Stress, obesity and streptococcal pharyngitis are commonly observed in HLA-Cw6-positive patients. Phenotypically, HLA-Cw6 has been found to be associated with guttate psoriasis. In addition, patients carrying the allele are more likely to have arm, leg and trunk involvement, and the Koebner phenomenon. Patients with psoriatic arthritis with HLA-Cw6 more often have early onset and tend to show cutaneous symptoms before musculoskeletal symptoms. HLA-Cw6-positive patients have been shown in several studies to be more responsive to methotrexate and ustekinumab. However, this difference in ustekinumab efficacy was only moderate in a post-hoc analysis of a pivotal phase III study. HLA-Cw6 positivity also tends to be less frequent in high-need patients who fail conventional therapy. Small studies have also investigated the role of HLA-Cw6 in remission of psoriasis during pregnancy, and with the comorbidities of photosensitivity and atherosclerosis. Given the diverse nature of psoriasis pathogenesis, as well as the difference of HLA-Cw6 positivity in different ethnic groups, more studies are needed to confirm the role of HLA-Cw6 in psoriasis.

Abstract
Geographic tongue is a chronic, inflammatory, and immune-mediated oral lesion of
unknown etiology. It is characterized by serpiginous white areas around the
atrophic mucosa, which alternation between activity, remission and reactivation
at various locations gave the names benign migratory glossitis and wandering
rash of the tongue. Psoriasis is a chronic inflammatory disease with frequent
cutaneous involvement and an immunogenetic basis of great importance in clinical
practice. The association between geographic tongue and psoriasis has been
demonstrated in various studies, based on observation of its fundamental
lesions, microscopic similarity between the two conditions and the presence of a
common genetic marker, human leukocyte antigen (HLA) HLA-C*06. The difficulty
however in accepting the diagnosis of geographic tongue as oral psoriasis is the
fact that not all patients with geographic tongue present psoriasis. Some
authors believe that the prevalence of geographic tongue would be much greater
if psoriatic patients underwent thorough oral examination. This study aimed to
develop a literature review performed between 1980 and 2014, in which
consultation of theses, dissertations and selected scientific articles were
conducted through search in Scielo and Bireme databases, from Medline and Lilacs
sources, relating the common characteristics between geographic tongue and
psoriasis. We observed that the frequency of oral lesions is relatively common,
but to establish a correct diagnosis of oral psoriasis, immunohistochemical and
genetic histopathological analyzes are necessary, thus highlighting the
importance of oral examination in psoriatic patients and cutaneous examination
in patients with geographic tongue.

Abstract
Psoriasis is a common inflammatory skin disease with complex etiology and chronic progression. To provide novel insights into the molecular mechanisms of regulation of the disease we performed RNA sequencing (RNA-Seq) analysis of 14 pairs of skin samples collected from psoriatic patients. Subsequent pathway analysis and an extraction of transcriptional regulators governing psoriasis-associated pathways was executed using a combination of MetaCore Interactome enrichment tool and cisExpress algorithm, and followed by comparison to a set of previously described psoriasis response elements. A comparative approach has allowed us to identify 42 core transcriptional regulators of the disease associated with inflammation (NFkB, IRF9, JUN, FOS, SRF), activity of T-cells in the psoriatic lesions (STAT6, FOXP3, NFATC2, GATA3, TCF7, RUNX1, etc.), hyperproliferation and migration of keratinocytes (JUN, FOS, NFIB, TFAP2A, TFAP2C), and lipid metabolism (TFAP2, RARA, VDR). After merging the ChIP-seq and RNA-seq data, we conclude that the atypical expression of FOXA1 transcriptional factor is an important player in psoriasis, as it inhibits maturation of naive T cells into this Treg subpopulation (CD4+FOXA1+CD47+CD69+PD-L1(hi)FOXP3-), therefore contributing to the development of psoriatic skin lesions.

The role of common protective alleles HLA-DRB1*13 among systemic autoimmune diseases. Genes Immun 2016; 18:1-7.

Abstract
Associations between human leukocyte antigen (HLA) and susceptibility to systemic autoimmune diseases have been reported. The predisposing alleles are variable among ethnic groups and/or diseases. On the other hand, some HLA alleles are associated with resistance to systemic autoimmune diseases, including systemic sclerosis, systemic lupus erythematosus and rheumatoid arthritis. Interestingly, DRB1*13 alleles are the protective alleles shared by multiple autoimmune diseases. DRB1*13:01 allele is protective in European populations and DRB1*13:02 in Japanese. Because alleles in multiple HLA loci are in strong linkage disequilibrium, it is difficult to determine which of the protective alleles is functionally responsible for the protective effects. Thus far, association studies suggested that DRB1*13:02 represents at least one of the causally associated protective factors against multiple systemic autoimmune diseases in the Japanese population. The protective effect of DRB1*13 alleles appears to overcome the predisposing effect of the susceptible alleles in heterozygous individuals of DRB1*13 and the susceptible allele. A gene dosage effect was observed in the associations of DRB1*13:02 with the protection from systemic autoimmune diseases; thus homozygous individuals are more effectively protected from the systemic autoimmune diseases than heterozygotes. DRB1*13:02 also confers protection against organ-specific autoimmune diseases and some infectious diseases. Several hypotheses can be proposed for the molecular mechanisms of the protection conferred by DRB1*13, some of which can explain the dominant effect of DRB1*13 molecules over the susceptible alleles, but the actual protective function of DRB1*13 requires further study. Understanding of the protective mechanisms of DRB1*13 may lead to the identification of targets for the curative treatment of systemic autoimmune diseases.

In addition to the core regulators, we identified 38 transcription factors previously not associated with the disease that can clarify the pathogenesis of psoriasis. To illustrate these findings, we analyzed the regulatory role of one of the identified transcription factors (TFs), FOXA1. Using ChIP-seq and RNA-seq data, we concluded that the atypical expression of the FOXA1 TF is an important player in the disease as it inhibits the maturation of naive T cells into the (CD4+FOXA1+CD47+CD69+PD-L1(hi)FOXP3-) regulatory T cell subpopulation, therefore contributing to the development of psoriatic skin lesions.

Abstract
Psoriasis is a multi-factorial heritable prototypical immune-mediated inflammatory disease, characterized by hyperproliferation of keratinocytes in the affected skin. There are no studies till date, to the best of our knowledge, about the association of HLA-C*06, the risk variant in the PSORS 1 susceptibility locus that confers the greatest risk for early onset of psoriasis, with the disease in South Indian Tamil patients with psoriasis. The present study was performed to determine the association of HLA-C*06 with psoriasis in the South Indian Tamil ethnic population. Three hundred and fifty-five cases of psoriasis and 360 healthy controls were included in this case-control study. Severity grading according to psoriasis area severity index (PASI) scoring was done in patients with psoriasis. PCR assays with sequence-specific primers (PCR-SSP) were used for specific detection of HLA-C*06. PCR with analysis of restriction fragment length polymorphism was used to distinguish between patients homozygous and heterozygous for HLA-C*06. We observed that those with the HLA-C*06-positive allele had a 3.5 times higher odds of having psoriasis compared to those without, [p < 0.0001, OR 3.5, 95 % CI (2.59-4.79)]. Among cases of psoriasis, it was noted that there was a significant association of HLA-C*06 positivity with female psoriatics [p = 0.006; OR 2.49 (1.28-4.87)] and early age of onset of psoriasis [p = 0.002; OR 2.04 (1.29-3.20)]. Our results suggest that the HLA-C*06 allele is positively associated with susceptibility to psoriasis, female gender and early onset of psoriasis in South Indian Tamils.

Abstract
Psoriasis is thought to be a multifactorial disease triggered by both genetic and environmental factors. The HLA-C locus on chromosome 6p21.33 remains the strongest susceptibility candidate locus in psoriasis. The strong association between psoriasis and the HLA-Cw6 allele has been well documented in various races. It is known that psoriatic patients with early onset are more likely to be familial and associated with HLA-Cw6. Familial occurrence of Japanese psoriasis is smaller than other populations. Furthermore, males are predominant over females in Japanese psoriasis. We investigated the relation between HLA-C alleles and age of onset, and in each gender for Japanese psoriasis, and discuss male predominance in the incidence of psoriasis in Japan. Four hundred forty six unrelated Japanese patients with psoriasis vulgaris and 557 sex- and age-matched unrelated Japanese healthy controls were investigated by genotyping. We confirmed the association between early-onset type of psoriasis with HLA-C*06:02 allele in Japanese. In addition, we detected the association between the late-onset type of psoriasis and the HLA-C*12:02 allele in Japanese. No significant differences in allele frequency were observed between females and males. Our results suggest that there is no genetic factor effect on male predominance in Japanese. In contract, the effect of environmental risk factors on the onset of Japanese psoriatic patients is stronger in males than in females. As a result, male predominant in psoriasis may occur in Japan.

Abstract
BACKGROUND Geographic tongue (GT) is the most frequent oral lesion in psoriatic patients (PP), and genetic involvement in these conditions has been described. The association of psoriasis with GT is still not clear, and the study of human leucocyte antigen (HLA) may help clarify this relation. OBJECTIVE The aim of this study was to investigate the association of HLA alleles with psoriasis vulgaris and GT. METHODS Fifty-eight Brazilian PP, 29 GT patients and 125 healthy controls individuals were selected. Information on demographic and clinical characteristics was collected. All patients underwent an oral examination and blood collection for HLA typing. RESULTS HLA-A did not show significant differences in frequencies among the groups. HLA-B*57 allele was more frequently found in PP and was not found in GT. HLA-B*58 allele was more frequently found in GT. HLA-C*06 and -C*18 alleles were associated with psoriasis. No significant differences in HLA-DRB1 and HLA-DQB1 were observed. CONCLUSION HLA-B*58 was associated with GT and HLA-B*57 was possibly associated with psoriasis. This suggested that some GT cases may represent true oral psoriasis and some may represent only GT. Therefore, it is necessary to make this distinction and increase our sample size to improve the correct diagnosis and treatment of these conditions.

Abstract
Psoriasis is a chronic relapsing disorder which shows variable clinical features. The long-term clinical study with many patients is important to elucidate the epidemiologic characteristics and clinical features of psoriasis. The purpose of this study was to analyze the epidemiologic characteristics and clinical features of psoriasis in Korean patients. Epidemiologic and clinic data and assessments for severity of extent and activity of psoriasis were collected from the medical records of 5084 patients, who had been newly diagnosed with psoriasis in the Psoriasis Clinic of Seoul National University Hospital between 1982 and 2012. The sex ratio of the psoriasis patients was 1.2:1 (male 54.6%, female 45.4%). The peak age of onset in males was 20s, while it was the teenage years in females. A total of 63.5% of patients developed psoriasis before 30 years of age. Family history of psoriasis was observed in 26.0% of patients. Moderate to severe extent of involvement were more frequently observed in male patients and patients under 30 years of onset age than in females and patients 30 years or over of onset age, respectively. Moderate to severe disease activity were also more frequently presented in male patients, but not in patients under 30 years of onset age. The most common morphological type was nummular (56.7%), followed by large plaque (28.5%) and guttate (8.5%). Nail involvement accompanied in 26.4% of patients. We demonstrated the epidemiologic and clinical characteristics of psoriasis in Korean patients.

Abstract
BACKGROUND Gaucher disease (GD) is caused by the reduced activity of lysosomal enzyme glucocerebrosidase, which leads to the accumulation of glucocerebroside in macrophages and a chronic stimulation of the immune system. GD is divided into 3 main types according to the presence or absence of neurological involvement and to its presentation (acute or chronic). Gaucher cells show an increase in their expression of HLA-DR antigens on their surface, and there is an increase in levels of antigen-presenting molecules. Over 100 diseases have already been associated to HLA antigens; however, this association has never been studied in GD. OBJECTIVES To analyze the variability of HLA genes in a Southern Brazilian sample of GD patients, to compare it with controls, and to look for associations with clinical manifestations. METHODOLOGY Thirty-one GD patients (24 mild, 4 moderate, and 3 severe) were included in the study. They were typed for HLA A, B, and DR and compared to 250 healthy controls. The clinical data were obtained from the review of medical records. RESULTS/DISCUSSION There was a significant difference in the frequency of B37 allele among patients when compared to controls (p=0.011, OR 13.28). An association was found between DR11 (p=0.008) and DR13 (p=0.011) alleles and the severity of the disease. DR11 allele seems to be associated to neurologic compromise, while DR13 seems to be associated to osteonecrosis. CONCLUSION Our data suggest a possible association of HLA variants and GD. The HLA variants must be further studied, for they seem to be a phenotype-modifier factor for GD.

Abstract
The main purpose of this report is to provide baseline gene frequencies of Knops blood group in the complement receptor 1 gene (CR1) in Korean population. In addition, possible relationship between the CR1 polymorphism and HLA specificities were studied, because the two systems had principal importance in immunity. CR1, which contains Knops antigens, was investigated by PCR-direct sequencing from 238 cord blood from Koreans. HLA data was archived from the enrolled cord blood units. Among the 7 SNPs, only 4843 (for KCAM antigen) and 4223 (for Yk(a)) nucleotide positions showed polymorphism. The genotype frequencies of KCAM were A/A (62.2%), A/G (33.2%), and G/G (4.6%); Yk(a) were C/C (29.4%), C/T (50%), and T/T (20.6%). KCAM (A/A) associated with HLA-DRB1(∗)13 (p=0.003, P(c)=0.0513); KCAM (G/G) with HLA-A(∗)30 (p<0.001, P(c)=0.0012). The Knops blood group system in Korean population has no diversity, except SNPs for KCAM and Yk(a), and the genotype of KCAM related with specific HLA alleles.

Abstract
The purpose of this study was to test for detectable serum levels of antibodies usually associated with immune-related diseases in children with Vernal keratoconjunctivitis (VKC) and seek for their family history of allergies and autoimmune disorders. The association of human leukocyte antigens (HLA) with VKC was also investigated. We enrolled 181 VKC children and assessed total and specific IgE, antithyroglobulin (AbTG), antithyroidperoxidase (AbTPO), antitransglutaminase (tTG), and antinuclear antibodies (ANA) by standard procedures. Class I and II HLA typing was also carried out following standard protocols, and it was compared with that of healthy subjects. Patients were positive for AbTG (22%), AbTPO (14.6%), and ANA (15.8%), and AbTG positivity was associated with VKC severity (mean ocular score ± SD positive vs. negative: 6.56 ± 2.1 vs. 4.82 ± 2.1; p = 0.03). We found that 12.2% of VKC cases had a positive family history for psoriasis, 6.4% for other cases of VKC, and 5.2% for thyroiditis, while 50.2% of them were atopic. The expression of HLA class I B37 was significantly higher in VKC patients than in controls (7.1% vs. 2.1%, p = 0.04), although not confirmed after multiple antigens testing analysis. Our study suggests a role of common components associated with immune-based diseases in the clinical expression of VKC.

Abstract
BACKGROUND The molecular basis of pathogenesis of psoriasis remains unclear, but one unifying hypothesis of disease aetiology is the cytokine network model. The class II cytokines (CF2) and their receptors (CRF2) are all involved in the inflammatory processes and single nucleotide polymorphisms (SNPs) in respective genes have been associated with psoriasis in a previous study of the Estonian population. OBJECTIVE We performed a replication study of 47 SNPs in CF2 and CRF2 genes in independent cohorts of psoriasis patients of two ethnic groups (Russians and Bashkirs) from the Volga-Ural region of Russia. METHODS DNA was obtained from 395 psoriasis patients of two ethnic groups from the Volga-Ural region of Russia and 476 ethnically matched controls. 47 SNPs in the loci of the genes encoding Class II cytokines and their receptors were selected by SNPbrowser version 3.5. Genotyping was performed using the SNPlex™ (Applied Biosystems) platform. RESULTS The genetic variant rs30461 previously associated in original case-control study in Estonians, was also associated in Russians (corrected P-value (Pc=0.008, OR=0.44), but did not reach statistical significance in the Bashkir population. Additionally, the haplotype analysis provided that CC haplotype formed by the SNPs rs30461 and rs955155 had a protective effect in Russians (Pc=0.0024, OR=0.44), supporting the involvement of this locus in the protection against psoriasis. Combined meta-analysis of three populations, including 943 psoriasis patients and 812 healthy controls, showed that the IL29 rs30461 C-allele was not associated with decreased risk of psoriasis (P=0.165, OR=0.68). Moreover, stratification of studies by ethnicity revealed a significant association in the European cohort (P=9.506E-006, OR=0.53). CONCLUSION Therefore, there is no overall evidence of association between psoriasis and SNP rs30461 of the IL29 gene, but there is some evidence to suggest that an association exists in Europeans. However, this current concept should be considered as preliminary and the results need to be confirmed in future independent studies.

Abstract
BACKGROUND Psoriasis, a common autoimmune disorder characterized by T cell-mediated keratinocyte hyperproliferation, is known to be associated with the presence of certain specific Human Leukocyte Antigen (HLA) alleles. AIM To evaluate distribution of HLA-A and HLA-B alleles and hence identify the susceptible allele of psoriasis from patients in Western India. MATERIALS AND METHODS The study design included 84 psoriasis patients and 291 normal individuals as controls from same geographical region. HLA-A and HLA-B typing was done using Serology typing. Standard statistical analysis was followed to identify the odds ratio (OR), allele frequencies, and significant P value using Graphpad software. RESULTS The study revealed significant increase in frequencies of HLA-A2 (OR-3.976, P<0.0001), B8 (OR-5.647, P<0.0001), B17 (OR-5.452, P<0.0001), and B44 (OR-50.460, P<0.0001), when compared with controls. Furthermore, the frequencies of HLA-A28 (OR-0.074, P=0.0024), B5 (OR-0.059, P<0.0001), B12 (OR-0.051, P=0.0002), and B15 (OR-0.237, P=0.0230) were significantly decreased in psoriasis patients. CONCLUSION This study shows the strong association of HLA-A2, B8, and B17 antigens with psoriasis conferring susceptibility to psoriasis patients from Western India, while the antigens HLA-A28, B5, and B12 show strong negative association with the disease.

Abstract
The human leukocyte antigen (HLA), the major histocompatibility complex (MHC) in humans has been known to reside on chromosome 6 and encodes cell-surface antigen-presenting proteins and many other proteins related to immune system function. The HLA is highly polymorphic and the most genetically variable coding loci in humans. In addition to a critical role in transplantation medicine, HLA and disease associations have been widely studied across the populations world-wide and are found to be important in prediction of disease susceptibility, resistance and of evolutionary maintenance of genetic diversity. Because recently developed molecular based HLA typing has several advantages like improved specimen stability and increased resolution of HLA types, the association between HLA alleles and a given disease could be more accurately quantified. Here, in this review, we have collected HLA association data on some autoimmune diseases, infectious diseases, cancers, drug responsiveness and other diseases with unknown etiology in Koreans and attempt to summarize some remarkable HLA alleles related with specific diseases.

Abstract
OBJECTIVES To determine which of the following is the best method to identify PSORS1-associated psoriasis in patients with psoriatic arthritis (PsA): age at disease onset or positive family history of disease. METHODS A total of 71 patients with PsA who met the CASPAR criteria were recruited on a randomized basis. The patients were stratified according to age at disease onset, with cutoff points at 25, 30, 35 and 40years of age. The alleles of locus Cw were analyzed by PCR-based methods, and their distribution was compared to that of 177 healthy blood donors. RESULTS HLA-Cw*0602-PSORS1- was associated with disease risk (56% vs. 18%) OR 5.8, 95%CI: 3.2-10.7, P=0.00001. A close relationship was established between this allele and onset of psoriasis under 30years of age (68% vs. 24%) OR 6.4, 95%CI: 2.3-18.2, P=0.0003. The relationship in turn lost significance above this age limit. An association was found between a family history of psoriasis and disease risk, though there was no specific cutoff point according to age at onset of the disease. Sixty-four percent of the subjects with positive family history were HLA-Cw*06 (+) compared to 44% of those without a family history, OR 2.3, 95% CI: 0.82-6.36, P=0.08. CONCLUSIONS In patients with PsA, the susceptibility effect of HLA-Cw*06 declines with increasing age of onset. Disease onset under or above 30years of age may contribute to differentiate type I vs. type II psoriasis in PsA populations, while the family history have a lesser contribution to such stratification.

Abstract
BACKGROUND Psoriasis is association with an overexpression of T-helper cell type 1(Th1) cytokines and relative underexpression of Th2 cytokines. The cytokine production is under genetic control, and certain allelic variants of cytokine genes are associated with higher or lower cytokine production in vitro and in vivo. OBJECTIVES We aimed to evaluate association of cytokine genes polymorphisms with psoriasis in the Korean population. METHODS We investigated the polymorphisms of IL-2 -330, IL-4 -590, IL-4 receptor +1902, IL-10 -1082 and -819, and IFN-gamma intron 1 in 114 psoriasis patients and 281 healthy normal controls in Korean. RESULTS IL-2 -330*G and IL-4 -590*C alleles significantly increased in psoriasis patients, especially late-onset group, compared to the control. The combined effect of IL-2 -330*G and IL-4 -590*C showed that the positive combination of IL-2 -330*G and IL-4 -590*C alleles were more significantly associated with the late-onset group of psoriasis patients than the controls. CONCLUSIONS These results suggest that the genetic polymorphisms of IL-2 and IL-4 genes can be susceptible to psoriasis in Korean, especially late-onset psoriasis group.

Abstract
BACKGROUND Psoriasis vulgaris is a skin disease with a complex immunological and genetic background, triggered by environmental factors. The association of human leukocyte antigens (HLA) and psoriasis has long been reported on population and familial studies. OBJECTIVES To review and discuss studies on psoriasis vulgaris and HLA, in Caucasian and non-Caucasian populations. METHODS The major population studies on psoriasis vulgaris and the associated HLA antigens and alleles are described and discussed based on a review of the current literature. RESULTS Population studies demonstrate the presence of different HLA specificities as well as extended haplotypes in patients with psoriasis, when compared to controls. Some alleles occur in a lower frequency in patients with psoriasis, indicating they could be protection alleles. In all studies which HLA class I was typed, Cw6 or Cw*0602 was present in a significant frequency in patients with psoriasis, mainly when early onset and positive family history were considered. HLA-DRB1*0701 was also present in a higher frequency in patients in different populations. CONCLUSIONS Different antigens and alleles from both HLA classes I and II were seen in a significantly higher frequency in patients with psoriasis vulgaris. HLA Cw*0602 and DRB1*0701 were represented in different reports, and the former was related mainly to psoriasis type I.

Abstract
BACKGROUND Psoriasis is a chronic T-cell-mediated immunological skin disease. The occurrence of the disease appears to differ with geography and ethnicity. There is a need for epidemiological data obtained from defined population-based studies, and the sex-specific differences observed in the natural history of the disease require more attention. OBJECTIVES To describe the occurrence and risk of psoriasis in Norway by age and sex. PATIENTS/METHODS A population-based health survey was conducted in 1998 in Norwegian twins aged 19-31 years. The present study is based upon the self-reported history of psoriasis among the 8045 questionnaire responders. RESULTS Altogether, 334 (4.2%) reported a positive history of psoriasis. There were no sex differences in the overall prevalence rates, but significantly higher point-prevalences emerged in females in the teenage-year intervals. A fairly linear increase in incidence rates by every 4-year age-interval peaked at a lower age in females. The mean age at onset was also significantly lower in females (14.8 years) than in males (17.3 years). The absolute risk of developing psoriasis appeared higher for females across the entire age range. However, by the age of 31 the cumulative risks were similar in females and males (0.056 and 0.053, respectively). CONCLUSIONS In this historical cohort of Norwegian twins, we find a high prevalence of psoriasis in congruence with previously reported data among whites in north-western Europe. We have found sex-specific characteristics in point-prevalences and incidence rates which may contribute to the understanding of the earlier age at onset of the disease in females.

Abstract
The aim of present study was to elucidate the role of the interleukin (IL)-24 gene in predicting risk for plaque-type psoriasis and to describe the linkage disequilibrium (LD) pattern emerging from the genes of IL-19, IL-20 and IL-24. Genes encoding IL-19, IL-20 and IL-24 locate in the region q32 of chromosome 1. The association between the single-nucleotide polymorphisms (SNPs) or haplotypes of the IL-24 gene and the susceptibility of psoriasis was not found. However, a significant protective effect of the combined haplotype CAAAC of IL-20 and IL-24 genes against plaque-type psoriasis was established (OR 0.154). Protective effect against psoriasis was also observed with haplotype TGGGT (OR 0.591) and haplotype CGAGT (OR 0.457). Performing a comprehensive analysis using the data regarding SNPs of IL-24 gene together with the previously published data regarding IL-19 and IL-20 SNPs, we identified two haplotype blocks within the region q32 of chromosome 1. The main result of the present study is that while the IL-19/IL-20 extended haplotype CACCGGAA is a significant susceptibility factor for psoriasis (previous study), IL-20/IL-24 haplotypes CAAAC, TGGGT and CGAGT have a significant protective effect. Nevertheless, family-based studies are required to confirm the impact of IL-19, IL-20 and IL-24 genes in the genetic predisposition for psoriasis.

Abstract
Psoriasis is a common inflammatory skin disease and is considered as T cell-mediated immune response. In this study, we analyzed T cell receptor alpha-chain variable region (TCR Valpha) usage in the lesions of psoriasis patients using 5'-RACE. As the results, Valpha1, -2, -7, -8, -10, -11, -12, and -23 were commonly detected in psoriatic lesions and comparison of expressions of these Valpha types between psoriasis patients and healthy individuals showed that Valpha1, -7, -11, and -12 were highly increased in psoriasis patients than in healthy individuals. Compared with atopy dermatitis patients, the expressions of Valpha1 and Valpha7 were increased in psoriasis patients. Then, to identify CDR3alpha of T cells infiltrated in psoriatic lesions, we examined which type of J gene segment was rearranged with Valpha1 or Valpha7, which the expressions was specifically increased in psoriatic lesions. The result showed that the V-J rearrangements between the examined patients were not equivalent and their frequencies were diverse, however, several common rearrangements such as Valpha1-Jalpha13, -23, -27, or -34 and Valpha7-Jalpha12, -33 were detected. The results in this study might provide the clue to define the characteristics of T cells associated with the pathogenesis of psoriasis.

Abstract
Summary Haplotype associations of the major histocompatibility complex (MHC) with psoriasis vulgaris (PV) have been demonstrated in different racial or ethnic populations. The objective of this study was to demonstrate the different haplotype associations of the MHC in Chinese patients with psoriasis according to the type of onset and their sex. One hundred and thirty-eight patients with PV and 149 normal control subjects without psoriasis were typed for HLA-A, -B, -C, -DQA1, -DQB1 and -DRB1 by using the PCR with sequence-specific primers. The results showed: (i) HLA-A*26 (26.1% vs. 12.1%, Pc < 1 x 10(-5)), -B*27 (17.03% vs. 1.01%, Pc < 1 x 10(-7)), -Cw*0602 (15.58% vs. 5.03%, Pc < 1 x 10(-2)), -DQA1*0104 (19.93% vs. 9.40%, Pc < 1 x 10(-3)), -DQA1*0201 (22.40% vs. 10.74%, Pc < 1 x 10(-3)), -DQB1*0303 (18.12% vs. 9.73%, Pc < 1 x 10(-7)), and -DRB1*0701/02 (26.09% vs. 9.73%, Pc < 1 x 10(-7)) were significantly increased in PV patients, while HLA-B*57, -DQB1*0201 were slightly increased in PV patients. HLA-Cw*0304 (5.07% vs. 14.43%, Pc < 1 x 10(-3)), -DQA1*0501 (5.79% vs. 14.09%, Pc < 0.05) were found to be negatively associated with PV, but HLA-A*2 (2.54% vs. 6.38%, Pc < 0.5) was decreased in PV patients without statistical significance. (ii) HLA-A*26-B*27 [P < 0.0001, odds ratio (OR) = 48.38], -A*26-Cw*0602 (P < 0.0001, OR = 11.84), -B*27-Cw*0602 (P < 0.0001, OR = undefined), -DRB1*0701/02-B*27 (P < 0.0001, OR = 22.62), -DRB1*0701/02-DQA1*0104 (P < 0.0002, OR = 3.59), -DRB1*0701/02-DQB1*0303 (P < 0.0001, OR = 5.63), -DQA1*0201-DQB1*0303 (P < 0.0002, OR = 7.77), -A*26-B*27-Cw*0602 (P < 0.0004, OR = undefined), -A*26-DRB1*0701/02-DQA1*0201-DQB1*0303 (P < 0.01, OR = undefined) were identified as risk haplotypes for patients with PV in China. (iii) HLA-A*26 -B*27 (P < 0.0001, OR = 58.47), -DQA1*0201-DQB1*0303 (P < 0.0001, OR = 8.62), -DRB1*0701/02 -DQA1*0104 (P < 0.0002, OR = 4.13), -DRB1*0701/02-DQB1*0303 (P < 0.0001, OR = 6.68) and -A*26-DRB1*0701-DQA1*0201 -DQB1*0303 (P < 0.006, OR = undefined) were only significantly associated with type I psoriasis compared with controls, while others showed no differences in either type I or type II psoriasis. (iv) These associated haplotypes with PV were not different by sex, except that the frequency of DRB1*0701/02-DQB1*0303 (P < 0.0001, OR = 10.14) was higher in male patients with psoriasis. To summarize, this study demonstrated a differential association of HLA and identified some special risk haplotypes in Chinese patients with PV compared with other ethnic or racial populations.

Abstract
BACKGROUND Type 1 T cells are hypothesized to be central in the immunopathogenesis of psoriasis. Through elaboration of interferon (IFN)-gamma, type 1 T cells regulate the expression of many 'downstream' inflammatory genes, including an array of chemokines that regulate leucocyte trafficking and activation in skin lesions. Accordingly, disease progression and/or severity might be controlled by the degree to which differing cytokines and chemokines are overexpressed in focal skin regions. To examine this possibility, we studied two forms of chronic psoriasis vulgaris that differ significantly in overall severity and progression: small plaque (SP) psoriasis occurring in Korean patients, and large plaque (LP) psoriasis occurring in North American patients. OBJECTIVES To characterize LP and SP psoriasis vulgaris with respect to expression of proinflammatory genes that define the type 1 T-cell axis in skin lesions [genes encoding interleukin (IL)-12, IFN-gamma, and IFN-gamma-regulated chemokines or inflammatory mediators]. METHODS Total cellular RNA of skin samples from groups of patients with LP or SP psoriasis was analysed by quantitative reverse transcription-polymerase chain reaction (TaqMan analysis) to compare the differences in mRNA expression of genes related to the IFN-gamma pathway. RESULTS The mRNA expression of keratin 16, CD25, IFN-gamma, IL-12 p40, signal transducer and activator of transcription-1, inducible nitric oxide synthase, IL-8, macrophage inflammatory protein-3alpha, monocyte chemoattractant protein-1, S100A12, IFN-gamma-inducible protein of 10 kDa, IFN-inducible T-cell alpha-chemoattractant and monokine induced by IFN-gamma was increased in the lesions of both LP psoriasis and SP psoriasis. However, IL-18 mRNA expression was significantly different in the lesions of LP psoriasis in comparison with those of SP psoriasis. CONCLUSIONS The results indicate that proinflammatory type 1 genes regulated by IFN-gamma are similarly increased in both SP and LP psoriasis, but a potential difference in IL-18 exists between these disease forms. The consistent activation of this set of genes argues for a central role of IFN-gamma as a molecular regulator of inflammation in these distinct subtypes of psoriasis vulgaris. In contrast, disease extent/severity must be controlled by yet other factors.
