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
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
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.

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
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
Dermatofibromas (DFs) are common, benign fibrous skin tumors that can occur at any skin site. In most cases, DFs are solitary and sporadic, but a few are multiple and familial, and the mechanisms leading to these lesions are currently unclear. Using exome sequencing, we have identified a heterozygous variant in a pedigree with autosomal dominant multiple familial DF within RND3 (c.692C>T,p.T231M) that encodes for the small GTPase RhoE, a regulator of the actin cytoskeleton. Expression of T231M-RhoE or RhoE depletion using CRISPR in human dermal fibroblasts increased proliferation and adhesion to extracellular matrix through enhanced β1 integrin activation and more disorganized matrix. The enzyme PLOD2 was identified as a binding partner for RhoE, and the formation of this complex was disrupted by T231M-RhoE. PLOD2 promotes collagen cross-linking and activation of β1 integrins, and depleting PLOD2 in T231M-RhoE-expressing cells reduced T231M-RhoE-mediated β1 integrin activation and led to increased matrix alignment. Immunohistochemical analysis revealed reduced expression of RhoE but increased expression of PLOD2 in the dermis of DF skin samples compared with that of the controls. Our data show that loss of RhoE function leads to increased PLOD2 activation, enhancing integrin activation and leading to a disorganized extracellular matrix, contributing to DF.

Abstract
In dermatology, biologics that block signaling pathways of TNF-α, IL-4/IL13, IL-17s, and IL-23 are widely used for the treatment of several inflammatory skin diseases, such as atopic dermatitis and psoriasis. They have shown excellent efficacy with an acceptable safety profile. However, these biologics targeting pathogenic cytokines and their receptors could modulate immunological balance, leading to the development of other inflammatory or autoimmune skin diseases in some cases. In this study, we present a patient who suffered pemphigus vegetans and showed an exacerbation of pemphigus foliaceus after secukinumab loading for the treatment of complicated generalized pustular psoriasis and pyoderma gangrenosum.

Abstract
Blockade of the secretion of immunoglobulins leads to their accumulation in plasma cells, resulting in condensed immunoglobulins in the rough endoplasmic reticulum of plasma cells, termed Russell bodies. They are sometimes found in lymphoplasmacellular inflammation of the intestinal mucosa and in lymphoid cell malignancies, but only very rarely in skin diseases. Here, we report an 86-year-old female who presented with a lesion with the prominent accumulation of Russell bodies underlying pseudocarcinomatous hyperplasia with fungal infection in the face. Immunohistochemical staining showed the cells containing Russell bodies to be positive for CD138 and the Russell bodies to be positive for immunoglobulin κ and λ light chains. The present case suggests that when inflammatory cell infiltration with abundant round intracellular eosinophilic materials is observed in the dermis, the dermal accumulation of Russell bodies should be considered in cases with reactive pseudocarcinomatous hyperplasia with fungal infection.

Abstract
Darier's disease (DD) is a rare autosomal dominantly inherited disorder. DD patients usually present with widespread keratotic eruptions with itching in the seborrheic regions that are exacerbated by various factors, including heat, sweat, and physical trauma. The SARS-CoV-2 (COVID-19) pandemic has stirred confusion among the medical community, including dermatologists, as this infection has been implicated in various skin conditions. Only a handful of reports have documented DD associated with COVID-19. Here, we report a 30-year-old male with Darier's disease whose symptoms were exacerbated following both COVID-19 vaccination and COVID-19 infection. The patient had noticed slight eruptions 7 years prior, but was not particularly concerned. After COVID-19 vaccination and infection, he had erythematous maculopapular lesions in large areas of the trunk and extremities. The previously reported pathogenic variant c.2255_2257del (p.(Ile752_Tyr753delinsAsn)) in ATP2A2 was detected in the present patient. Oral etretinate greatly improved his DD manifestations. As far as we know, the present patient is the first genetically confirmed DD case who showed both COVID-19 infection- and vaccination-related DD exacerbations independently. We think that the further accumulation of DD cases exacerbated by COVID-19 infection/vaccination is needed to clarify the mechanisms of DD aggravation.

Since the myositis of anti-ARS-positive patients is characterized by a unique set of non-myopathic manifestations, including interstitial lung disease, mechanic's hands, and arthralgia, the patients are classified as having anti-synthetase syndrome. Autoantibodies have been identified to eight kinds of ARSs. Of the other 12 ARSs, eight are components of the "OJ" multi-synthetase complex. Autoantibodies to the four remaining ARSs (CysARS, ValARS, SerARS, and TrpARS) have not been reported to be present in patients with inflammatory myopathies. In this study, we first screened samples from more than 300 Japanese patients majorly consisting of those with dermatomyositis (DM) by our established in-house ELISA to find autoantibodies against the four ARSs described above. Since sera from two DM patients specifically reacted to CysARS or ValARS, we determined their reactivities by immunoprecipitation (IP) with the corresponding recombinant proteins and IP-Western blotting with cellular extract. One patient had several features found in anti-synthetase syndrome, but the other did not. The clinical differences among the various anti-ARS antibodies should be explored in a future work.

Abstract
Self-healing collodion baby (SHCB), also called "self-improving collodion baby", is a rare mild variant of autosomal recessive congenital ichthyosis and is defined as a collodion baby who shows the nearly complete resolution of scaling within the first 3 months to 1 year of life. However, during the neonatal period, it is not easy to distinguish SHCB from other inflammatory forms of autosomal recessive congenital ichthyosis, such as congenital ichthyosiform erythroderma. Here, we report a case study of two Japanese SHCB patients with compound heterozygous mutations, c.235G>T (p.(Glu79∗))/ c.1189C>T (p.(Arg397Cys)) and c.1295A>G (p.(Tyr432Cys))/ c.1138delG (p.(Asp380Thrfs∗3)), in CYP4F22, which encodes cytochrome P450, family 4, subfamily F, polypeptide 22 (CYP4F22). Immunohistochemically, inflammation with the strong expression of IL-17C, IL-36γ, and TNF-α was seen in the skin at birth. CYP4F22 is an ultra-long-chain FA ω-hydroxylase responsible for ω-O-acylceramide (acylceramide) production. Among the epidermal ceramides, acylceramide is a key lipid in maintaining the epidermal permeability barrier function. We found that the levels of ceramides with ω-hydroxy FAs including acylceramides and the levels of protein-bound ceramides were much lower in stratum corneum samples obtained by tape stripping from SHCB patients than in those from their unaffected parents and individuals without SHCB. Additionally, our cell-based enzyme assay revealed that two mutants, p.(Glu79∗) and p.(Arg397Cys), had no enzyme activity. Our findings suggest that genetic testing coupled with noninvasive ceramide analyses using tape-stripped stratum corneum samples might be useful for the early and precise diagnosis of congenital ichthyoses, including SHCB.
