Abstract
Autosomal recessive congenital ichthyoses (ARCI) is a genetically heterogeneous condition that can be caused by pathogenic variants in at least 12 genes, including ABCA12. ARCI mainly consists of congenital ichthyosiform erythroderma (CIE), lamellar ichthyosis (LI) and harlequin ichthyosis (HI). The objective was to determine previously unreported pathogenic variants in ABCA12 and to update genotype-phenotype correlations for patients with pathogenic ABCA12 variants. Pathogenic variants in ABCA12 were detected using Sanger sequencing or a combination of Sanger sequencing and whole-exome sequencing. To verify the pathogenicity of a previously unreported large deletion and intron variant, cDNA analysis was performed using total RNA extracted from hair roots. Genetic analyses were performed on the patients with CIE, LI, HI and non-congenital ichthyosis with unusual phenotypes (NIUP), and 11 previously unreported ABCA12 variants were identified. Sequencing of cDNA confirmed the aberrant splicing of the variant ABCA12 in the patients with the previously unreported large deletion and intron variant. Our findings expand the phenotype spectrum of ichthyosis patients with ABCA12 pathogenic variants. The present missense variants in ABCA12 are considered to be heterogenous in pathogenicity, and they lead to varying disease severities in patients with ARCI and non-congenital ichthyosis with unusual phenotypes (NIUP).

Abstract
Autosomal recessive congenital ichthyosis (ARCI) is a genetically heterogeneous disorder manifesting aberrant skin scaling and increased transepidermal water loss (TEWL). Current treatments for ARCI are limited and sub-optimal. We studied a 27-year-old man with ARCI resulting from a homozygous missense variant in TGM1 (transglutaminase 1). RNA-sequencing of lesional skin revealed aberrant JAK-STAT signalling, providing a rationale for innovative treatment with a Janus kinase inhibitor. We prescribed oral tofacitinib (11 mg daily) for 26 weeks. Rapid improvements in erythema and fissuring manifested within the first month. Sustained reductions in 5-D itch scale and Dermatology Life Quality Index (DLQI) scores were also observed. TEWL decreased for the first 10 weeks but increased thereafter. Tofacitinib down-regulated inflammatory genes and pathways, while enhancing skin barrier markers. Moreover, TGM1 distribution was normalized although enzymatic activity remained deficient. This study suggests that oral tofacitinib may be a useful therapy to consider in patients with ARCI.

Abstract
Generalized pustular psoriasis (GPP), a rare form of psoriasis, is characterized by neutrophil-rich, sterile pustules. In Japan, GPP has intractable and rare disease designation, which allows patients to access support from national and local governments for medical expenses. Previously, similar numbers of patients in Tokyo and Hokkaido have been shown to have GPP designation, despite different population sizes. Here, we determine whether there are regional differences in the proportion of patients receiving GPP designation status in Japan and aim to identify causal factors. In this descriptive, retrospective cohort study, publicly available data were collected on the number of patients with intractable and rare disease designation for GPP in each prefecture and age classification (April 2018-March 2021). Three other designated intractable and rare disease cohorts were included: pemphigus, rare skin diseases, and all diseases. The primary outcome was the standardized morbidity ratio (SMR) of patients at prefecture level (observed numbers divided by expected). Regional differences were compared with the statistical expectation for the total population and age distribution of each prefecture. Regional differences were observed in all cohorts. Overall, 1910 patients had GPP as a designated intractable and rare disease in 2020. Regional differences in SMRs for GPP were observed with high SMRs (≥1.5) in Hokkaido, Tottori, Kagawa, and Miyazaki, and low SMRs (<0.6) in Gunma and Kanagawa. Regional differences in SMRs for GPP did not correlate with the number of medical doctors or dermatologists or internal migration. The number of medical doctors or dermatologists correlated with SMRs in the rare skin diseases and total cohorts. Regional differences in Japan exist in the number of patients with GPP who have an intractable and rare disease designation. Managing rare diseases is an important public health issue, and further research is required to elucidate the factors contributing to these differences.

Abstract
Analyzing colocalization of single cells with heterogeneous molecular phenotypes is essential for understanding cell-cell interactions, and cellular responses to external stimuli and their biological functions in diseases and tissues. However, existing computational methodologies identified the colocalization patterns between predefined cell populations, which can obscure the molecular signatures arising from intercellular communication. Here, we introduce DeepCOLOR, a computational framework based on a deep generative model that recovers intercellular colocalization networks with single-cell resolution by the integration of single-cell and spatial transcriptomes. Along with colocalized population detection accuracy that is superior to existing methods in simulated dataset, DeepCOLOR identified plausible cell-cell interaction candidates between colocalized single cells and segregated cell populations defined by the colocalization relationships in mouse brain tissues, human squamous cell carcinoma samples, and human lung tissues infected with SARS-CoV-2. DeepCOLOR is applicable to studying cell-cell interactions behind various spatial niches. A record of this paper's transparent peer review process is included in the supplemental information.

Abstract
Background To develop precision medicine for atopic dermatitis (AD), it is critical to establish relevant biomarkers. However, the characteristics of various biomarkers have not been fully understood. We previously carried out the Biomarkers to Predict Clinical Improvement of AD in Patients Treated with Dupilumab (B-PAD) study, a comprehensive nationwide study in Japan, to explore biomarkers for AD. Objective The aim of this study is to find biomarkers associated with objective and subjective clinical findings in patients with moderate-to-severe AD based on the B-PAD study and to identify biomarkers sensitive enough to assess the severity of AD. Methods We performed the B-PAD study as a consortium composed of 19 medical facilities in Japan, enrolling 110 patients with moderate-to-severe AD. We evaluated the Eczema Area and Severity Index (EASI) for objective assessment as well as the Patient-Oriented Eczema Measure (POEM) and a numeric rating scale for pruritus (pruritis-NRS) for subjective assessment, measuring 19 biomarkers at baseline. Results We found that 12, 6, and 7 biomarkers showed significant and positive associations with the EASI, POEM, and pruritis-NRS, respectively. Most of the biomarkers associated with either the POEM or the pruritis-NRS were included among the biomarkers associated with EASI. Of the biomarkers examined, CCL26/eotaxin-3 and SCCA2 were the most capable of assessing severity for EASI, as shown by the 2 kinds of receiver operating characteristic analyses, respectively, whereas lactate dehydrogenase was the best for both the POEM and pruritis-NRS, again using the 2 analyses. Conclusion We found biomarkers associated with the EASI, POEM, and pruritis-NRS, respectively, based on the B-PAD study. Moreover, we identified CCL26/eotaxin-3 and/or SCCA2 as the biomarkers having the greatest ability to assess severity in the EASI; lactate dehydrogenase did the same for the POEM and pruritis-NRS. These findings will be useful in treating patients with moderate-to-severe AD.

Abstract
Whole-exome and whole-genome sequencing have become widespread in approximately the last 15 years, and the predisposing factors and pathomechanisms of inflammatory keratinization diseases, which have been unknown for a long time, have gradually been revealed. Hence, various inflammatory keratinization diseases are recognized to cause innate immunity hyperactivation. Therefore, we have been advocating for the clinical entity, "autoinflammatory keratinization diseases (AiKDs)" since 2017. AiKDs are inflammatory keratinization diseases caused by autoinflammatory-related pathomechanisms in the skin. The aberrant activation of innate immunity and the resultant autoinflammation in the epidermis and the superficial dermis in AiKDs cause hyperkeratosis in the epidermis. Our initially proposed concept of AiKDs included generalized pustular psoriasis and related conditions, pityriasis rubra pilaris type V, and familial keratosis lichenoides chronica. Since then, the number of diseases known to be AiKDs has increased as previously unknown disease-causing factors and pathogenetic mechanisms of inflammatory keratinization diseases have been clarified one by one. To date, porokeratosis, hidradenitis suppurative, keratosis linearis with ichthyosis congenita and sclerosing keratoderma (KLICK) syndrome, and AiKDs associated with epidermal growth factor receptor (EGFR) deficiency or with hepatitis and autism have been recognized as AiKDs. The concept of AiKDs is considered extremely useful in our precise understanding of the pathogeneses behind inflammatory keratinization diseases and our appropriate treatment method selection. The number of AiKDs is expected to grow with the clarification of the pathomechanisms of further inflammatory keratinization diseases.

Abstract
Because absorption of the oral drug pazopanib depends on gastric pH, concomitant use of proton pump inhibitors (PPIs)/potassium-competitive acid blockers (P-CABs) may inhibit pazopanib absorption by elevating the gastric pH. This study investigated to what extent the concomitant use of PPIs/P-CABs affects treatment with pazopanib in patients with soft tissue sarcoma. We retrospectively reviewed the medical records of patients with soft tissue sarcoma who had received at least one dose of pazopanib at our institution, among which those who had received concomitant PPIs/P-CABs were included in this analysis. Using paired sample t tests, the frequency of dose reduction or interruption of pazopanib and the major adverse events (AEs) were compared in each patient between periods with and without PPIs/P-CABs. Between January 2018 and December 2022, eight patients were eligible. The median time to treatment failure (TTF) was 3.9 months (2.1-38.2 months). Two patients received concomitant PPIs/P-CABs throughout their treatment with pazopanib. Among the other six patients, dose reduction or interruption of pazopanib occurred less frequently (P = 0.021), and neutropenia tended to be milder (P = 0.155) with the concomitant use of PPIs/P-CABs. Although the concomitant use of PPIs/P-CABs had no apparent effect on TTF in patients undergoing pazopanib treatment, dose reduction or interruption of pazopanib occurred less frequently, and neutropenia was milder, suggesting that concomitant use of PPIs/P-CABs might decrease the pharmacological activity of pazopanib.

Abstract
Pathogenic variants in ABCA12 are important causative genetic defects for autosomal recessive congenital ichthyoses (ARCI), which include congenital ichthyosiform erythroderma (CIE), harlequin ichthyosis, and lamellar ichthyosis. In addition, pathogenic variants in ABCA12 are known to cause a localized nevoid form of CIE due to recessive mosaicism. We previously reported siblings who carried an ABCA12 variant but did not show a "congenital" phenotype. They were considered to have pityriasis rubra pilaris (PRP). Here, we present a further patient with ABCA12 variants whose phenotype was not congenital ichthyosis, in an independent family. Notably, these three patients had geographic unaffected areas. Such areas are not usually found in patients with ARCI who have ABCA12 variants, suggesting mild phenotypes for these patients. Interestingly, the histological features of the ichthyotic lesions in these patients resembled those of PRP. All three patients had homozygous pathogenic missense variants in ABCA12. Our findings expand the phenotypic spectrum of patients with ABCA12 variants.

Abstract
BACKGROUND Congenital ichthyoses sometimes present with severe skin symptoms that significantly affect the patient's quality of life (QOL). Symptomatic treatments are the mainstay therapies, and their efficacy is limited and inadequate. OBJECTIVE To assess the disease severity and QOL in patients with congenital ichthyoses, and to investigate the effectiveness of current treatments. METHODS We conducted a questionnaire-based Japan-wide epidemiological survey of patients with congenital ichthyosis who received medical care from 1 January 2016-31 December 2020. Effectiveness of past and current treatments was assessed. The outcomes were the physician's assessment, disease severity assessed using the clinical ichthyosis score (CIS), and the disease burden estimated using the Dermatology Life Quality Index (DLQI), the Children's Dermatology Life Quality Index (CDLQI), and the Infants' Dermatitis Quality of Life Index. RESULTS One hundred patients with 14 ichthyosis subtypes from 47 institutes were included in the final analysis. The CDLQI score showed a positive correlation with CIS (rs = 0.59, p = 0.004), while the DLQI score showed no significant correlation (rs = 0.13, p = 0.33). All existing medications were effective for many patients. Etretinate improved QOL and reduced CIS, but side effects including bone growth retardation were reported. Decreased treatment willingness was observed in patients with very low and very high CIS. CONCLUSION QOL scores were found to correlate with CIS in children, but not in adults. Considering the adverse events, it is speculated that etretinate is not indicated for children with mild cases. Petrolatum was the most commonly used medication, even in patients who were reluctant to receive treatment.

Abstract
Epidermal lipids play important roles in skin homeostasis and diseases. Psoriasis is an inflammatory disease characterized by keratinocyte hyperproliferation and Th17 immune responses. We previously reported that ethanolamine-type lysoplasmalogen (P-LPE), preferentially produced by group IIF secreted PLA2 (sPLA2-IIF/PLA2G2F) that is expressed in the suprabasal epidermis, promotes epidermal hyperplasia in psoriatic inflammation. Herein, we show that forcible degradation of epidermal P-LPE by topical application of recombinant lysophospholipase D (LyPls-PLD) from Thermocrispum, a lysoplasmalogen-specific hydrolase, attenuated epidermal hyperplasia and inflammation in imiquimod-induced and K5.Stat3C-transgenic mouse psoriasis models. In humans, P-LPE levels were elevated in the tape-stripped stratum corneum of patients with psoriasis. Moreover, in primary cultured human epidermal keratinocytes, aberrant cell proliferation and activation by psoriatic cytokines were sPLA2-IIF/P-LPE-dependent and were suppressed by the addition of LyPls-PLD with a decrease in P-LPE. These findings confirm that the sPLA2-IIF/P-LPE axis in the epidermis indeed regulates psoriasis, that P-LPE is a lipid biomarker that predicts the severity of psoriasis, and that pharmacological removal of this bioactive lipid is useful to prevent the disease. Thus, our study may lead to the development of drug discovery and diagnostic techniques based on this pathway.

Abstract
As extramammary Paget's disease (EMPD) sometimes invades and metastasizes from the skin to the mucosa, radical surgical resection of these lesions is often difficult. The purpose of this study was to analyse the association between surgical margins and survival as well as the benefit of functional preservation over complete resection, in patients with EMPD. We retrospectively analysed 230 patients diagnosed with EMPD between 1969 and 2020. Patient and treatment characteristics were recorded. Since our centre is a specialized hospital and almost all patients were referred from other hospitals, we reviewed their referral letters. Prognostic factors and survival time were also analysed. Among 230 patients, 78 (33.9%) had positive margins. The presence of margin positive lesions increased the local recurrence rate but was not significantly correlated with survival. Of all the patients who had received a thorough explanation about the surgical procedure in the referring hospital, 43.8% were scheduled for surgeries that would result in functional impairment, and all of them had function-preserving surgeries at our hospital with a 10-year survival rate of 100%. Our result suggest that less invasive surgery preserves anogenital and urethral function may be an acceptable option for EMPD treatment.

Abstract
This is the English version of the Japanese guidance for biologics in treating atopic dermatitis (AD). The signaling pathway mediated by interleukin (IL)-4 and IL-13 contributes to type 2 inflammatory responses and plays an important role in the pathogenesis of AD. IL-31 is a cytokine mainly produced by activated T cells and is known to be involved in the pruritus of AD. Biologics for AD have been approved, including dupilumab, an anti-IL-4 receptor α antibody that was approved for expanded use in AD in 2018. In 2022, nemolizumab, an anti-IL-31 receptor α antibody, was approved for pruritus of AD, and tralokinumab, an anti-IL-13 antibody, was approved for AD. Physicians who intend to use these drugs should sufficiently understand and comply with the contents of the guidelines prepared by the Japanese Ministry of Health, Labour, and Welfare to promote the optimal use of the drugs. In treatment with biologics, it is important to consider disease factors (activity and severity), treatment factors (dosage and administration as well as the efficacy and safety), and patients' background characteristics (age and comorbidities) and share this information with patients when choosing treatment options. This guidance was developed for board-certified dermatologists who specialize in treating AD, and for promoting the proper use of biologics, taking into account the variety of factors in individual patients.

Abstract
This small-scale prospective study investigated the changes in antigen-specific IgG4 (sIgG4) that occur during long-term dupilumab treatment in patients with atopic dermatitis. While dupilumab has been reported to have an inhibitory effect on B-cell maturation, the increase in sIgG4 during dupilumab treatment may indicate that dupilumab indirectly improves allergies in those predisposed to them. We present the possibility of a new therapeutic effect of long-term dupilumab use.

Abstract
Pathogenic variants in MPO, which encodes the myeloperoxidase, were reported as causative genetic defects in several cases of generalised pustular psoriasis (GPP) in addition to patients with myeloperoxidase deficiency in 2020. However, which clinical subtypes of GPP patients have pathogenic variants in MPO remains largely undetermined, and elucidating this is clinically important. The present report outlines a mild case of GPP with a rare missense heterozygous variant, c.1810C>T p.(Arg604Cys), in MPO. Our structural analysis and functional assays to measure myeloperoxidase activity suggest that the present MPO substitution is a hypomorphic variant in MPO. Thus, the mild phenotype of the present GPP patient might be associated with an incomplete hypomorphic loss-of-function variant in MPO. Additionally, the severe intractable edematous pustules and erythema improved dramatically after five rounds of granulocyte and monocyte adsorption apheresis (GMA) therapy. This is the first report of GMA treatment for GPP associated with a pathogenic variant in MPO, as far as we know. Our findings suggest that GMA might be a useful and powerful tool for controlling GPP in patients with myeloperoxidase deficiency.

Abstract
As mentioned above, the cathepsin family is a group of important proteases that are deeply involved in the development of various skin disorders of cornification and inflammation, including AiKDs. The cathepsin family members are considered to play essential roles in the keratinocyte proliferation/differentiation and inflammatory pathways in the skin.

Abstract
The kinesin superfamily protein 20B (KIF20B), also known as M-phase phosphoprotein-1, is a plus-end-directed motor enzyme for cytokinesis. Anti-KIF20B antibodies have been reported in idiopathic ataxia, but no previous studies have examined anti-KIF20B antibodies in systemic autoimmune rheumatic diseases (SARDs). We aimed to establish methods for detecting anti-KIF20B antibodies and to investigate the clinical significance of these antibodies in SARDs. Serum samples from 597 patients with various SARDs and 46 healthy controls (HCs) were included. Fifty-nine samples that had been examined by immunoprecipitation using the recombinant KIF20B protein produced by in vitro transcription/translation were used for establishing the ELISA cutoff with the same recombinant protein for measuring the anti-KIF20B antibodies. The ELISA performed well, showing close agreement with the immunoprecipitation results (Cohen's κ >0.8). The ELISA results for 643 samples showed the prevalence of anti-KIF20B to be higher in the systemic lupus erythematosus (SLE) patients than in the HCs (18/89 vs. 3/46, P = 0.045). Since no SARD other than SLE had higher frequencies of anti-KIF20B antibodies than those of the HCs, we investigated the clinical characteristics of anti-KIF20B antibody-positive cases in SLE. The score on the SLE Disease Activity Index-2000 (SLEDAI-2K) was significantly higher for the anti-KIF20B-positive SLE patients than for the anti-KIF20B-negative SLE patients (P = 0.013). In a multivariate regression analysis of the anti-single-stranded deoxyribonucleic acid, anti-double-stranded deoxyribonucleic acid, and anti-KIF20B antibodies, the presence of anti-KIF20B antibody was significantly associated with high SLEDAI-2K scores (P = 0.003). Anti-KIF20B antibodies were found in ~20% of patients with SLE and were associated with high SLEDAI-2K scores. Much larger cohort and longitudinal studies are needed to confirm the association between anti-KIF20B antibodies and SLE.

Abstract
We read with great interest ‘Chronic activation of Toll-like receptor 2 induces an ichthyotic skin phenotype’ by Tagoe et al.1 Their findings expand our recent understanding of how certain kinds of autoinflammation contribute to the pathogenesis of ichthyosis. Inspired by the report by Tagoe et al., we suggest that their unique autosomal recessive congenital ichthyosis in vitro models have several characteristics in common with autoinflammatory keratinization diseases.

Abstract
Recently, Gong et al. reported two substitutions, p.(Gly50Glu) and p.(Gly50Arg), located at the last amino acid of the estimated signal peptide in kallikrein11 (KLK11) in three independent ichthyosiform erythroderma or erythrokeratoderma pedigrees (Gong et al., Br J Dermatol, 2023). Here, we present a further case of autosomal dominant congenital ichthyosiform erythroderma caused by the p.(Gly50Glu) substitution in KLK11; the patient had sharply demarcated pigmented hyperkeratotic lesions. Thus, p.(Gly50Glu) in KLK11 might represent a recurrent variant underlying this recently reported autosomal dominant disorder of cornification, and the large hyperkeratotic pigmented plaques seen in all patients may represent a pathognomonic part of the phenotype.

Abstract
Our Research Group for Rare and Intractable Skin Diseases operates within the Project for Research on Intractable Diseases of the Ministry of Health, Labour, and Welfare of Japan and is conducting research on eight rare intractable skin diseases. Five of these are monogenic disorders (epidermolysis bullosa, congenital ichthyoses, oculocutaneous albinism, pseudoxanthoma elasticum, and hereditary angioedema), and for a sixth [generalized pustular psoriasis (GPP)], genetic predisposing factors are important. This review introduces our activities for raising public awareness of these six intractable hereditary skin diseases and summarizes our recent achievements in clarifying the situation of medical treatments for these diseases in Japan. We note our current progress in elucidating the pathogeneses of these diseases and in developing new treatment methods, and we discuss our progress in establishing clinical practice guidelines. A nationwide survey on epidermolysis bullosa and a clinical survey on congenital ichthyoses are progressing. The Angioedema Activity Score and the Angioedema Quality-of-Life Questionnaire, the latter of which is a quality-of-life evaluation tool, have been established for hereditary angioedema. Registries of patients with oculocutaneous albinism and pseudoxanthoma elasticum have been created, and the registry for the latter has achieved its target of 170 cases. For GPP, the results of our survey on clinical practice were published in 2021. Information regarding all six of these hereditary skin diseases has been disseminated to academic societies, medical professionals, patients, and the general public.

Abstract
Immune-related sclerosing cholangitis (irSC) is relatively rare and its clinical characteristics are not well known. In this study, we aimed to summarize the clinical features of irSC. Clinical data were collected retrospectively from 1,393 patients with advanced malignancy treated with immune-checkpoint inhibitors (ICIs) between August 2014 and October 2021. We analyzed patients with immune-related adverse events of liver injury (liver-irAEs) and compared irSC and non-irSC groups. Sixty-seven patients (4.8%) had a liver-irAE (≥ grade 3) during the follow-up period (median, 262 days). Among these, irSC was observed in eight patients (11.9%). All patients in the irSC group were treated with anti-PD-1/PD-L1 antibodies. Compared with the non-irSC group, the irSC group showed mainly non-hepatocellular liver injury (87.5 % vs 50.8 %, P = 0.065), and had elevated serum inflammatory markers (e.g., CRP and NLR) and biliary enzymes (e.g., GGTP and ALP) at the onset of liver-irAEs. Furthermore, most patients with irSC had abdominal pain. In the non-irSC group, the liver injury of 23 patients improved only with the discontinuation of ICIs, and 22 patients improved with medication including prednisolone (PSL). Conversely, almost all patients (n=7) in the irSC group were treated with PSL, but only two patients experienced an improvement in liver injury. We found that irSC is characterized by a non-hepatocellular type of liver injury with abdominal pain and a high inflammatory response and is refractory to treatment. Further examination by imaging is recommended to detect intractable irSC in cases with these characteristics.

Abstract
Studies have reported an association between elevated neutrophil-to-lymphocyte ratio (NLR) and poor prognosis in patients with melanoma treated with ipilimumab. However, it remains unclear whether NLR is useful in Japanese patients with melanoma, and if so, what is the optimal cut-off value. We retrospectively examined 38 patients who received ipilimumab from August 2015 to November 2021 at Nagoya University Hospital. We divided patients into two groups: 1-2 versus 3-4 cycles of ipilimumab. In univariate analysis, baseline neutrophil count and NLR were significantly higher in patients who discontinued ipilimumab within 2 cycles. With receiver operating characteristic analysis, the optimal NLR cut-off value was found to be 3.4 (area under the curve, 0.75; 95% confidence interval, 0.58-0.92). In multivariate logistic regression analysis, baseline NLR >3.4 was an independent risk factor for ipilimumab discontinuation (odds ratio, 15.6; 95% confidence interval, 3.0-82) that was significantly associated with shorter progression-free survival (PFS) (p = 0.003, log-rank test). In conclusion, NLR >3.4 is useful for selecting Japanese patients with melanoma who might have better PFS with ipilimumab-containing treatment. Because the optimal NLR cut-off value in this study was lower than values in American and European studies, it possibly differs by race. Hence, it should be extrapolated to Japanese patients with caution.
