Clinical Characteristics of Cryopyrin-Associated Periodic Syndrome and Long-Term Real-World Efficacy and Tolerability of Canakinumab in Japan: Results of a Nationwide Survey. Arthritis Rheumatol 2024. [PMID: 38268504 DOI: 10.1002/art.42808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 01/09/2024] [Accepted: 01/22/2024] [Indexed: 01/26/2024]
Abstract
OBJECTIVE We assess the clinical characteristics of patients with cryopyrin-associated periodic syndrome (CAPS) in Japan and evaluate the real-world efficacy and safety of interleukin-1 (IL-1) inhibitors, primarily canakinumab. METHODS Clinical information was collected retrospectively, and serum concentrations of canakinumab and cytokines were analyzed. RESULTS A total of 101 patients were included, with 86 and 15 carrying heterozygous germline and somatic mosaic mutations, respectively. We identified 39 mutation types, and the common CAPS-associated symptoms corresponded with those in previous reports. Six patients (5.9% of all patients) died, with four of the deaths caused by CAPS-associated symptoms. Notably, 73.7% of patients (100%, 79.6%, and 44.4% of familial cold autoinflammatory syndrome, Muckle-Wells syndrome, and chronic infantile neurological cutaneous articular syndrome/neonatal onset multisystem inflammatory disease, respectively) achieved complete remission with canakinumab, and early therapeutic intervention was associated with better auditory outcomes. In some patients, canakinumab treatment stabilized the progression of epiphysial overgrowth and improved height gain, visual acuity, and renal function. However, 23.7% of patients did not achieve inflammatory remission with crucial deterioration of organ damage, with two dying while receiving high-dose canakinumab treatment. Serological analysis of canakinumab and cytokine concentrations revealed that the poor response was not related to canakinumab shortage. Four inflammatory nonremitters developed inflammatory bowel disease (IBD)-unclassified during canakinumab treatment. Dual biologic therapy with canakinumab and anti-tumor necrosis factor-α agents was effective for IBD- and CAPS-associated symptoms not resolved by canakinumab monotherapy. CONCLUSION This study provides one of the largest epidemiologic data sets for CAPS. Although early initiation of anti-IL-1 treatment with canakinumab is beneficial for improving disease prognosis, some patients do not achieve remission despite a high serum concentration of canakinumab. Moreover, IBD may develop in CAPS after canakinumab treatment.

Enhancing evidence-informed policymaking in medicine and healthcare: stakeholder involvement in the Commons Project for rare diseases in Japan. RESEARCH INVOLVEMENT AND ENGAGEMENT 2023; 9:107. [PMID: 38031179 PMCID: PMC10685685 DOI: 10.1186/s40900-023-00515-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 11/14/2023] [Indexed: 12/01/2023]
Abstract
BACKGROUND Although stakeholder involvement in policymaking is attracting attention in the fields of medicine and healthcare, a practical methodology has not yet been established. Rare-disease policy, specifically research priority setting for the allocation of limited research resources, is an area where evidence generation through stakeholder involvement is expected to be effective. We generated evidence for rare-disease policymaking through stakeholder involvement and explored effective collaboration among stakeholders. METHODS We constructed a space called 'Evidence-generating Commons', where patients, family members, researchers, and former policymakers can share their knowledge and experiences and engage in continual deliberations on evidence generation. Ten rare diseases were consequently represented. In the 'Commons', 25 consecutive workshops were held predominantly online, from 2019 to 2021. These workshops focused on (1) clarification of difficulties faced by rare-disease patients, (2) development and selection of criteria for priority setting, and (3) priority setting through the application of the criteria. For the first step, an on-site workshop using sticky notes was held. The data were analysed based on KJ method. For the second and third steps, workshops on specific themes were held to build consensus. The workshop agendas and methods were modified based on participants' feedback. RESULTS The 'Commons' was established with 43 participants, resulting in positive effects such as capacity building, opportunities for interactions, mutual understanding, and empathy among the participants. The difficulties faced by patients with rare diseases were classified into 10 categories. Seven research topics were identified as priority issues to be addressed including 'impediments to daily life', 'financial burden', 'anxiety', and 'burden of hospital visits'. This was performed by synthesising the results of the application of the two criteria that were particularly important to strengthen future research on rare diseases. We also clarified high-priority research topics by using criteria valued more by patients and family members than by researchers and former policymakers, and criteria with specific perspectives. CONCLUSION We generated evidence for policymaking in the field of rare diseases. This study's insights into stakeholder involvement can enhance evidence-informed policymaking. We engaged in comprehensive discussions with policymakers regarding policy implementation and planned analysis of the participants' experiences in this project.

Abstract
This is an abridged edition of English version of the Clinical Practice Guidelines for the Management of Atopic Dermatitis 2021. Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. In Japan, from the perspective of evidence-based medicine, the current strategies for the treatment of AD consist of three primary measures: (i) use of topical corticosteroids, tacrolimus ointment, and delgocitinib ointment as the main treatment of the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling, and advice about daily life. In the present revised guidelines, the description about three new drugs, namely, dupilumab, delgocitinib, and baricitinib, has been added. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
BACKGROUND The efficacy of small molecule inhibitors for intracellular signal mediators varies among the individuals, and their mechanism of action is broad. A phosphodiesterase 4 inhibitor apremilast shows a dramatic effect on a certain proportion of psoriatic patients by modulating the cellular metabolism and regulating the production of pro-inflammatory molecules. However, it is unclear to which disease subtype this drug benefits. While psoriasis is a Th17-mediated disease, how immune cells are affected by the modulation of cellular metabolism is not fully evaluated, either. OBJECTIVE This study aims to identify the indices which predict the efficacy of apremilast in psoriasis, and to investigate the impact of metabolic activity in immune cells on the psoriatic pathogenesis. METHODS The association of treatment efficacy with clinical and laboratory data of the 58 psoriatic patients was evaluated. The reflector of the associated index was also sought among the indices of cellular metabolic pathways by use of an extracellular flux analyzer. RESULTS There was a correlation between clinical improvement and the serum lactate dehydrogenase (LDH) level in the patients treated with apremilast but not in those with biologics. Serum LDH level did not correlate with the cutaneous disease severity but correlated with the oxygen consumption rate of blood T cells. CONCLUSION Psoriatic patients with high serum LDH level can be benefitted by apremilast. The serum LDH level reflects the augmented respiratory activity of T cells in psoriasis. Our results would highlight the importance of regarding metabolic skew in immune cells as a treatment target in psoriasis.

A prospective, phase II study on the safety and efficacy of negative pressure closure for the stabilization of split-thickness skin graft in large or muscle-exposing defects: The NPSG study. J Dermatol 2021; 48:1350-1356. [PMID: 34028872 DOI: 10.1111/1346-8138.15970] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 04/28/2021] [Accepted: 04/29/2021] [Indexed: 11/29/2022]
Abstract
Several studies have demonstrated the usefulness of negative pressure closure (NPC) for the stabilization of skin grafts because it provides a uniform pressure to the graft. The results of our previous retrospective study also suggested the superiority of NPC over tie-over methods for the stabilization of split-thickness skin graft (STSG) in large or muscle-exposing defects. However, the usefulness of NPC for graft stabilization is yet to be fully established. This prospective, phase II clinical study was conducted to investigate the safety and efficacy of NPC for the stabilization of STSG in large or muscle-exposing defects. Patients who would require STSG for reconstruction of defects in the trunk and extremities other than hands and feet measuring >10 cm in the longest diameter or with muscle exposure were enrolled. NPC was applied for skin graft stabilization. Seven patients who had received wide excision of malignant tumors and resulted in muscle-exposed skin defects were included. All patients underwent meshed STSG. The mean size of the defect was 94.5 cm2 (range 63.6-164.9). The mean time from the skin graft harvesting to the NPC stabilization was 15.6 min (range 10.7-19.5). The mean survival rate of the skin graft at postoperative day 7 and 10 was 98.7% (range 97-100) and 96.5% (range 89.4-98.4), respectively. No adverse events associated with the procedure were observed. This prospective study provided further evidence of the safety and efficacy of NPC for STSG stabilization in patients with large or muscle-exposing skin defects.

Invasive and in situ lesions of squamous cell carcinoma are independent factors for postoperative surgical-site infection after outpatient skin tumors surgery: A retrospective study of 512 patients. J Dermatol 2021; 48:497-501.

Abstract
Surgical-site infection (SSI) is one of the major postoperative complications in surgery, which can cause significant morbidity. However, factors associated with SSI in dermatological surgery are not well understood. Here, we retrospectively investigated 512 patients who underwent outpatient surgery for skin tumors at the University of Tsukuba Hospital to analyze factors associated with postoperative SSI. The overall incidence of SSI was 28 (5.5%). Univariate logistic regression analysis revealed that SSI was significantly associated with invasive squamous cell carcinoma (iSCC), Bowen's disease (BD), actinic keratosis (AK), longer diameter of defects, presence of ulcer, reconstruction with full-thickness skin graft and local skin flaps, medical history of diabetes mellitus, and use of immunosuppressive agents. However, in the multivariate analysis only iSCC, BD, and AK retained significance. The frequencies of SSI in iSCC, BD, and AK were 22% (13/58 patients), 15.6% (5/32), and 25% (2/8), respectively; however, the frequency of other non-SCC tumors was only 1.9% (8/414). χ2 -Tests revealed that the frequency of SSI in iSCC, BD, and AK were all significantly higher than in non-SCC tumors, with the frequencies being more than eight times higher. These results suggest that invasive and in situ lesions of SCC are independent risk factors of SSI development after outpatient skin surgery.

Abstract
Psoriasis is an autoinflammatory/autoimmune skin disease and the epitome of an exaggerated primary inflammatory response in the surface barrier tissue. Despite the efficacy of dimethyl fumarate, an electrophilic drug for psoriasis management, there is a paucity of mechanistic evidence in vivo. In response to electrophiles, the Kelch-like erythroid cell-derived protein with cap-n-collar homology-associated protein 1/nuclear factor erythroid 2-related factor 2 (NRF2) system mediates a myriad of cytoprotective mechanisms, including the regulation of excessive inflammatory response and epidermal differentiation. Because the psoriasiform tissue reaction comprises neutrophil infiltration and parakeratotic scaling, it is hypothesized that Nrf2 not only regulates inflammatory responses but also maintains epidermal differentiation, a hallmark of epidermal homeostasis. By using the imiquimod-induced cutaneous inflammation model, an exaggerated inflammatory response and impaired epidermal differentiation in Nrf2-/- mice was detected. Dimethyl fumarate treatment in Nrf2+/+ mice attenuated a psoriasiform tissue reaction and rescued epidermal differentiation, which was not observed in Nrf2-/- mice. In accordance with the fact that psoriasis plaques form well-demarcated parakeratotic lesions in association with the psoriasiform tissue reaction, the lesional skin showed reduced expression levels of NRF2 and its downstream target genes compared with nonlesional skin. In conclusion, Nrf2 attenuates the psoriasiform tissue reaction and underscores the mechanistic legitimacy of the electrophile-based approach for the management of psoriasis.

Abstract
BACKGROUND Patients with steroid-resistant bullous pemphigoid (BP) require an appropriate treatment option. OBJECTIVE A multicenter, randomized, placebo-controlled, double-blind trial was conducted to investigate the therapeutic effect of high-dose intravenous immunoglobulin (IVIG; 400mg/kg/day for 5days) in BP patients who showed no symptomatic improvement with prednisolone (≥0.4mg/kg/day) administered. METHODS We evaluated the efficacy using the disease activity score on day15 (DAS15) as a primary endpoint, and changes in the DAS over time, the anti-BP180 antibody titer, and safety for a period of 57days as secondary endpoints. RESULTS We enrolled 56 patients in this study. The DAS15 was 12.5 points lower in the IVIG group than in the placebo group (p=0.089). The mean DAS of the IVIG group was constantly lower than that of the placebo group throughout the course of observation, and a post hoc analysis of covariance revealed a significant difference (p=0.041). Furthermore, when analyzed only in severe cases (DAS≥40), the DAS15 differed significantly (p=0.046). The anti-BP180 antibody titers showed no difference between the two groups. CONCLUSION IVIG provides a beneficial therapeutic outcome for patients with BP who are resistant to steroid therapy.

Abstract
This study investigated rare variants associated with atopic dermatitis. We performed exome analyses on 37 patients who were diagnosed with atopic dermatitis by board-certified dermatologists and had total serum IgE levels greater than 1000 IU/ml. The exome analysis identified seven variants with <1% allele frequency in Asian (ASN) population of 1000 Genomes Project phase 1 data and >5% allele frequency in the atopic dermatitis exome samples. We then conducted a replication study using 469 atopic dermatitis patients with total serum IgE ≥1000 IU/ml and 935 Japanese controls to assess the presence of these 7 candidate variants. The replication study confirmed that CYP27A1 rs199691576 (A/G) was associated with atopic dermatitis with high serum IgE levels (P = 0.012, odds ratio = 2.1). CYP27A1 is involved in the metabolism of vitamin D3, which plays important roles in modulating immune function. Previous studies have reported polymorphisms in vitamin D pathway genes that are associated with allergy-related phenotypes. Our data confirm the importance of genes regulating the vitamin D pathway in the development of atopic dermatitis.

Abstract
Bronchiolitis is a rare condition mainly affecting the intralobular conducting and transitional small airways. The present study describes a case of severe airflow limitation in a patient with ulcerative colitis who developed toxic epidermal necrolysis following mesalazine therapy. Forced expiratory volume in one second was decreased and a flow-volume curve showed airflow limitation, but the single-breath diffusing capacity of the lung for carbon monoxide (DLCO) and DLCO divided by alveolar volume (DLCO/VA) were not decreased. This rare clinical condition should be considered as a differential diagnosis for subjects presenting with sub-acutely developed airflow obstruction if the findings in chest computed tomography scans demonstrate hyperinflation but few low-attenuation areas. Relatively well-preserved DLCO and DLCO/VA provide a clue to establishing the correct diagnosis.

B-Myb enhances proliferation and suppresses differentiation of keratinocytes in three-dimensional cell culture. Arch Dermatol Res 2014; 306:375-84.

Abstract
B-Myb (Mybl2) is a member of the Myb gene family of transcription factors involved in the control of cell growth, differentiation, and apoptosis. The effects of B-Myb on keratinocyte proliferation and differentiation have not yet been clarified. The present study was performed to examine the role of B-Myb in proliferation and differentiation of the spontaneously immortalized human skin keratinocyte cell line HaCaT and normal human keratinocytes with formation of a stratified epidermoid structure in air-liquid interface three-dimensional culture. B-Myb was expressed specifically in undifferentiated normal keratinocytes and downregulated during differentiation. The constitutive overexpression of B-Myb in HaCaT cells during air exposure-induced differentiation resulted in an undifferentiated phenotype, i.e., thickening of the stratified layers, suppression of differentiation marker expression, and retention of proliferative activity with activation of cell cycle regulatory proteins in the S and G2/M phases. In contrast, suppression of B-Myb caused their downregulation and constrained proliferation with retention of differentiation capacity. These findings suggested that B-Myb plays an important role in maintenance of the undifferentiated phenotype of keratinocytes in the basal epidermal layer.

Abstract
Neurofibromatosis type I (NF1) is associated with typical hypervascular tumors, including neurofibroma, glioma, malignant peripheral nerve sheath tumors (MPNST) and glomus tumors. Previously, we and other groups reported that neurofibromas showed high-level expression of vascular endothelial growth factor (VEGF), a potent angiogenic factor involved in neovascularization. However, the molecular mechanism underlying the upregulation of VEGF in neurofibromas remains unclear. In this study, we examined the effects of Nf1 gene silencing on VEGF expression in Schwann cell and non-Schwann cell line and the upstream mTOR-HIF-1α - VEGF pathway in Schwann cell line. The results indicated that Nf1 gene silencing by lentiviral-mediated RNA interference resulted in elevated expression of VEGF, HIF-1α and phosphorylated mTOR at the protein level. The results obtained from Nf1 gene silencing in murine Schwann cell line analogously suggest that NF1 gene haploinsufficiency in human tumor Schwann cells may directly elicit upregulation of VEGF expression without the tumor microenvironment by activation of the mTOR-HIF-1α - VEGF pathway. We also showed that interleukin-6 is upregulated in Nf1 gene knock-down Schwann cells at the protein level.

Abstract
Graft-versus-host disease (GVHD) is a frequent complication of bone marrow transplantation (BMT) that can be classified as acute or chronic. Characteristic cutaneous manifestations of acute GVHD, which generally occurs within 3 months following BMT, include maculopapular exanthema and perifollicular papular lesions. Psoriasiform skin eruption as a manifestation of acute GVHD is rare. We report the case of a 4-year-old boy who developed a generalized psoriasiform eruption shortly after undergoing an allogeneic BMT. Histologic features of both psoriasis and acute GVHD were present.

The POU domain transcription factors Oct-6 and Oct-11 negatively regulate loricrin gene expression in keratinocytes: association with AP-1 and Sp1/Sp3. Arch Dermatol Res 2013; 305:371-8.

Abstract
Loricrin is a major component of the epidermal cornified cell envelope, and is expressed only in terminally differentiated keratinocytes. This cell differentiation-specific expression pattern suggests specific regulatory mechanisms for activation and suppression of loricrin gene transcription in differentiated keratinocytes. Here, we identified a regulatory element in the proximal promoter region of the loricrin gene involved in suppression of its expression in keratinocytes. A database search indicated that this sequence contained a POU transcription factor binding motif. Electrophoretic mobility shift assay revealed that Oct-1, Oct-6, and Oct-11 actually bind to the motif. Constructs with point mutations in the POU-binding motif showed increased reporter activity, indicating that the POU factors negatively regulate loricrin gene transcription. Cotransfection experiments suggested that Oct-6 and Oct-11 suppress loricrin gene transcription in a cooperative manner with AP-1 and Sp1. Furthermore, in vitro experiments indicated that the Oct-6 and Oct-11 can physically associate with both AP-1 factors and Sp1/Sp3. These findings indicate that Oct-6 and Oct-11 contribute to the regulation of loricrin gene transcription via interaction with AP-1 factors and Sp1/Sp3.

Abstract
Yin-Yang-1 (YY1) is a member of the GLI-Krüppel family of transcription factors, and both YY1 mRNA and protein expression have been identified in a number of different tissues and cell types suggesting that it is expressed both constitutively and ubiquitously. In epidermal tissue, however, we reported previously that YY1 protein is expressed at high levels in undifferentiated basal keratinocytes and is downregulated during differentiation toward the suprabasal layers. This differential expression pattern during keratinocyte differentiation suggests that YY1 may have an important role in regulating keratinocyte differentiation. In this study, we examined the role of YY1 in differentiation of the human keratinocyte cell line HaCaT using air-liquid interface three-dimensional culture. The constitutive overexpression of YY1 in HaCaT cells during air exposure-induced differentiation resulted in an undifferentiated phenotype, thickening of the stratified layers, suppression of differentiation marker expression, and retention of proliferative activity. These findings suggested that YY1 may have an important role in maintenance of the undifferentiated phenotype of keratinocytes in the basal epidermal layer, and that reduction of YY1 expression in the suprabasal layers may allow keratinocytes to differentiate and move toward the upper layers of the epidermis.

Abstract
A 52-year-old woman with advanced non-small cell lung cancer was admitted to our hospital with melena and palpable purpura which appeared on her lower legs. She had been taking gefitinib for about 2 months before admission. A skin biopsy revealed leukocytoclastic vasculitis in the superficial dermis and immunofluorescence also showed the presence of C3 depositions within the blood vessel walls, which led to a diagnosis of Henoch-Schönlein purpura. The purpura gradually improved with topical steroids and bed rest; however, gefitinib had to be discontinued because of a growing papulopustular rash with intense itching, and as a result of the discontinuation, both types of skin lesions resolved. Two months later, she resumed gefitinib treatment since her level of CEA began to rise. Even though the papulopustular rash developed after the readministration of gefitinib, there had been no evidence of Henoch-Schönlein purpura recurrence during 2.5 years follow-up. It has been reported that adult onset Henoch-Schönlein purpura is often associated with malignancy. This case, however, suggests that not only drug eruption but also paraneoplastic vasculitis should be considered in the differential diagnosis of palpable purpura in patients with non-small cell lung cancer receiving treatment with gefitinib.

Abstract
BACKGROUND Tumor lysis syndrome (TLS) is rare in the treatment of solid tumors, but it may occur in myelolymphoproliferative diseases. METHODS A 58-year-old man with bulky metastatic melanoma of the liver was treated with transcatheter arterial infusion of cisplatin and embolization therapy. The patient developed classic signs of TLS within 24 h of chemotherapy, including acute renal failure. RESULTS The patient was treated with aggressive hydration, allopurinol, and repeated hemodialysis. He gradually improved and his biochemical markers returned to normal. CONCLUSION TLS is an uncommon, but potentially life-threatening, complication in melanoma and other solid tumors. It is important for oncologists to recognize this complication and prevent its development if bulky metastatic disease and several pre-existing risk factors, such as multiple and bulky liver metastases, elevated lactate dehydrogenase, and hyperuricemia, are present.

Abstract
Severe local skin reactions to subcutaneous injection of interferon beta-1b in multiple sclerosis are rare, and only 12 cases of severe skin reaction due to interferon beta-1b have been reported to date. We report two cases of severe skin reactions in multiple sclerosis patients following the injection of subcutaneous interferon beta-1b. In case 1, after five years of treatment, a painful indurated erythematous lesion appeared at the injection site on the left buttock. On histological analysis, the lesion showed septal and lobular panniculitis with lymphocytic infiltration. In case 2, cutaneous ulceration was surrounded by painful induration, which developed at the injection site on the right thigh after four years of treatment. The lesions resolved rapidly after discontinuation of interferon beta-1b treatment in both cases. Here, we review cases of similar lesions caused by interferon beta-1b reported in the literature, and discuss the characteristics, mechanism, treatment, and prevention of such lesions.
