Survey of diversity awareness and environment among members of the Pediatric Rheumatology Association of Japan.

BACKGROUND: Diversity management has gained traction in Japan. The Pediatric Rheumatology Association of Japan (PRAJ) has an Advisory Committee for Diversity Promotion with a broader focus on promoting diversity. The objectives of this study were to better understand the problems faced by PRAJ members regarding the work environment, childcare and nursing care, and work-life balance. METHODS: A web-based questionnaire was administered to members of the PRAJ and 79 responses were evaluated. RESULTS: Of the respondents, 73% were male and 27% were female. A total of 14% worked for more than 12 h on weekdays, and 22% worked for more than 60 h per week and 38% had fewer than 4 days off per month. Regarding childcare, 54% of the respondents were raising preschool children and 83% had taken parental leave for less than 1 year. A total of 17% of participants had family members in need of care. For both childcare and caregiving, the burden was greater for women. Only 18% of the respondents reported a well-balanced work-life balance, and the most common reasons for a lack of balance were not having enough time, heavy workload, and heavy housework load. CONCLUSIONS: The working hours of the respondents were long, and female members had a greater burden of childcare and caregiving, which was considered a barrier to the career development of women. In the future, there will be a need to promote a sense of equality in diverse human resources, develop support for family life, and shorten working hours.

Subcutaneous Panniculitis-like T-cell Lymphoma with a HAVCR2 Mutation Diagnosed after 10 Years of Treatment with Glucocorticoids and Cyclosporine as Lupus Panniculitis.

Subcutaneous panniculitis-like T cell lymphoma (SPTCL) is a very rare cutaneous T cell lymphoma that has been reported to be associated with autoimmune disorders but is most commonly associated with systemic lupus erythematosus. We herein report a 26-year-old man thought to have lupus panniculitis (LP) treated for 10 years with corticosteroids and cyclosporine. After several relapses with panniculitis, he was finally diagnosed with SPTCL, which was confirmed to have a HAVCR2 mutation for p.Tyr82Cys. We emphasize that rheumatologists should be aware of the possibility of SPTCL, despite its rare appearance, when making a diagnosis of LP or when encountering clinical manifestations that are not consistent with LP.

Different pharmacoresistance of focal epileptic spasms, generalized epileptic spasms, and generalized epileptic spasms combined with focal seizures.

OBJECTIVE: Among standard treatments for infantile spasms, adrenocorticotropic hormone (ACTH) is reported as the best treatment, but ACTH is ineffective in one-half of the patients. To establish precision medicine, we examined pharmacoresistance of focal epileptic spasms (ES), generalized ES, and generalized ES combined with focal seizures, diagnosed based on the revised seizure classification of ILAE in 2017. METHODS: We conducted a retrospective nationwide study in Japan on the long-term seizure outcome of ES. Long-term seizure outcome was evaluated by seizure-free rate, seizure-free period, and Kaplan-Meier curve. Seizure-free was defined as seizure control for longer than 2 months. RESULTS: From the medical history of 501 patients, 325 patients had generalized ES only (GES group) at the start of the first treatment, 125 patients had generalized ES after focal seizure onset (FS-GES group), seven patients had focal ES after focal seizure onset (FS-FES group), and 24 patients had generalized ES combined with focal seizures after focal seizure onset (FS-GES + FS group). Seizure-free period of ES (generalized ES and focal ES) [mean (95% confidence interval)] was 2.7 (0.0-5.4) months in GES group, 1.1 (0.1-2.2) months in FS-GES group, 1.0 (0.2-1.9) months in FS-GES + FS group, and 0.1 (-0.2-0.5) months in FS-FES group. Seizure-free rate, seizure-free period, and Kaplan-Meier curve of generalized ES were almost the same in GES group and FS-GES group, with characteristics of superior response to ACTH. Mean seizure-free period of generalized ES combined with focal seizures was significantly shorter in FS-GES + FS group than in GES group. Mean seizure-free period of focal ES in FS-FES group was extremely short with exceedingly early relapse. SIGNIFICANCE: Pharmacoresistance was different in generalized ES, focal ES, and generalized ES combined with focal seizures. ES with focal features or with focal seizures may have focal lesions, thus consider surgical options earlier in the course.

Safety and response to influenza vaccine in patients with systemic-onset juvenile idiopathic arthritis receiving tocilizumab.

OBJECTIVE: We investigated the safety and efficacy of administering influenza vaccines to patients with systemic-onset juvenile idiopathic arthritis (sJIA) treated with tocilizumab. PATIENTS AND METHODS: The subjects were 27 sJIA patients treated with tocilizumab and 17 healthy age- and sex-matched volunteers. Serum samples were collected prior to and 4-7 weeks after vaccination. Hemagglutination inhibition values of the vaccine were taken as the antibody titers. The duration of tocilizumab administration and the daily doses of prednisolone per unit body weight were analyzed to identify factors affecting the responses of the sJIA patients to influenza vaccination. We questioned all the subjects about whether they had contracted influenza and whether they had had adverse reactions to the influenza vaccination. We compared steroid doses in sJIA patients before and after vaccination to document any worsening of the underlying disease. RESULTS: The efficacy of influenza vaccination did not differ significantly between the sJIA group and the healthy controls. The duration of tocilizumab administration did not affect the response of the sJIA patients to the influenza vaccination. None of the sJIA patients experienced either severe adverse reactions or disease exacerbation after the influenza vaccination. CONCLUSION: We found that sJIA patients treated with tocilizumab could be effectively and safely immunized with the influenza vaccine.

[Two patients with childhood-onset Behcet's disease successfully treated by anti-tumor necrosis factor therapy].

Behçet's disease (BD) is a multisystem immune-mediated inflammatory disorder. The choice of treatments depends on organ involvements and its severity. The treatments for pediatric patients usually consist of corticosteroids and immunosuppressants, but some of them are refractory to these treatments. Recently, tumor necrosis factor alpha (TNF-alpha) appears to play an important role in the immunopathogenesis in BD. We describe two patients with childhood-onset BD, successfully treated by anti-TNF agents. One patient, a 18-year-old male, was diagnosed as having BD at 8 years of age. He developed abdominal pain and bloody diarrhea at 17 years of age. Gastrointestinal endoscopic examination revealed esophageal and ileocolic ulceration consistent with intestinal BD. Methylpredonisolone pulse therapy and immunosuppressants were administrated, but did not respond. Infliximab infusions (4 mg/kg) were given at weeks of 0, 2, 6, and then every 8 weeks. A dramatic improvement in gastrointestinal symptoms and extraintestinal manifestations were observed. Another patient, a 9-year-old girl, developed recurrent oral ulcers and folliculitis at 4 years of age. She was diagnosed as having BD at 6 years of age, and treated with colchicines, corticosteroids and immunosuppressive agents. She was suffering from fever, malaise, and arthralgia in addition to mucocutaneous manifestation. At 8 years of age, etanercept was started at a dosage of 25 mg subcutaneously twice a week. A resolution of the systemic and mucocutaneous symptoms was achieved. Furthermore, she was free from corticosteroids in three months. Anti-TNF therapy would be a good choice for juvenile BD refractory to conventional treatments.

Effect of anakinra on arthropathy in CINCA/NOMID syndrome.

CINCA/NOMID is an autoinflammatory disorder characterized by the triad of neonatal onset of cutaneous symptoms, chronic meningitis, and recurrent fever and it presents with distinctive osteoarthropathy, synovitis mainly of the large joints and overgrowth of epimetaphyseal cartilage, particularly of the long bones. The cartilage overgrowth eventually causes osseous overgrowth and deformity that persists beyond skeletal maturity and leads to limb length discrepancy, joint contracture, and early degenerative arthropathy. Autoinflammation in CAPS/NOMID has been proven to derive from excessive release of interleukin-1 (IL-1). It has been well documented that the IL-1 receptor antagonist anakinra (Kineret(R)) helps mitigate systemic inflammation in the disorder. However, a general consensus has not been reached on its beneficial effect on osteoarthropathy. The case of a girl with CINCA/NOMID syndrome who showed dramatic improvement of osteoarthropathy after anakinra treatment is reported. A 4-year-old girl suffered at the age of 10 months from a generalized urticarial skin lesion with recurrent episodes of fever and growth disorder. Blood examination revealed persistent massive neutrophilia, anemia and intense acute phase response. She manifested knee joint swelling with limited ROM when she was 20 months old and was diagnosed as being CINCA/NOMID based on characteristic findings of radiograph despite negative CIAS1 mutation. Radiological examination demonstrated metaphyseal fraying and cupping and widening of the growth plate in the distal femur. MR imaging showed mottled gadolinium enhancement at the chondrosseous junction. Neither significant joint effusion nor synovitis was identified. At 2 years and 7 months of age, anakinra, 2 mg/kg/day given by regular daily subcutaneous injections, was started. A few days after the initiation of the treatment, her clinical symptoms and laboratory findings of active inflammation were promptly alleviated. She was not able to walk unaided prior to the treatment, but she walked independently 1 month after the treatment. Follow-up radiographs and MR imaging showed that growth plate widening and gadolinium enhancement at the chondrosseous junction were less conspicuous. Furthermore, longitudinal growth of the femur and tibia was identified during 20 months of observation.

[Infliximab therapy for three adolescent patients with refractory Takayasu's arteritis].

Takayasu's arteritis (TA) is a chronic idiopathic inflammatory disease affecting primarily aorta and its proximal branches. Pediatric patients with TA tend to have more severe clinical course and be refractory to conventional treatments compared with adults. Corticosteroids are major treatment of TA, however, high dose is required to get remission. Particularly, adolescent patients are usually suffering from side-effects of excessive dose of corticosteroids. Immunosuppressants are added expecting the corticosteroid sparing agents. However, some patients, such as HLA-B52 positive, tend to be registant to these conventional treatments. Recently, several reports showed the efficacy of Infliximab, anti-tumor necrosis factor (TNF) alpha monoclonal antibody, for adult patients with refractory TA. We described three cases of adolescents with TA treated with Infliximab. It was initially effective in all three patients. However, serious infusion reaction occurred in one of them during 11(th) times of Infliximab infusion and she discontinued the therapy. Other two patients showed good response in initial phase, but clinical manifestations and laboratory findings became worse after several months. In these patients with secondary failure to Infliximab, increased dosage and shortening the interval of infusions provided effectiveness again. Infliximab would be a good choice for adolescent patients with TA refractory to conventional treatments. However, we should carefully monitor safety and efficacy of this agent considering its peculiarity.

[Clinical and histological experience of labial lip biopsy in juvenile Sjögren syndrome].

The therapeutic efficacy of corticosteroids and immunosuppressants on secretary glands of children with Sjögren syndrome was investigated examining the lip-biopsy specimen on both lymphocyte infiltration and fibrosis. Six children with primary Sjögren syndrome and two children with lupus-associated secondary Sjögren syndrome were evaluated according to the intensity of therapy. The shorter the term of medications of corticosteroids and immunosuppressants were, the lesser the extents of lymphocyte infiltration and fibrosis were, and the lower the doses of medications were, the lesser the efficacy was. Thus, in childhood Sjögren syndrome, appropriate corticosteroids and immunosuppressants may provide the suppressive effects on the progressive inflammatory destruction of secretary glands. Further evaluation with more patients is needed to determine the inclusion criteria of these treatments for sicca syndrome, especially in cases with no other organ involvement.
