    Currently, there are no specific diagnostic investigations for systemic juvenile idiopathic arthritis (s-JIA). Various investigations are considered when making a differential diagnosis. During the 5th Pediatric Rheumatology Workshop held in 2017, we interviewed 17 Japanese pediatric rheumatology experts about the investigations they conduct in the initial diagnostic process for s-JIA. Bone marrow aspiration was preferred by 82% of experts. Routine use of joint magnetic resonance imaging and measurement of serum IL-18 for an initial diagnostic approach appeared to be controversial. Fluorodeoxyglucose-positron emission tomography or Gallium scintigraphy were not frequently conducted. Although each investigation was known to play a certain role in the diagnosis of s-JIA, they were often not conducted for reasons such as radiation exposure, invasiveness, availability of the investigation in that hospital, and health insurance coverage. In addition, investigations necessary for diagnosis should be selected on an individual basis because patients with s-JIA show diverse initial manifestations. There was consensus among the experts that exclusion of malignancy is important when diagnosing s-JIA; therefore, selected investigations should be performed carefully.

    <Objective> To clarify factors associating with transition readiness in youth/young adults with childhood-onset rheumatic diseases( coRD) and their parents/caregivers. <Methods> We enrolled 28 patients with coRD aged 10 years and older and their parents/caregivers. We evaluated transition readiness both in youth/young adults with coRD and in their parents/caregivers by using Transition readiness checklist. Mental disorders and overprotection of parents/caregivers were subjectively evaluated by their attending doctors. <Results> We did not find any association between achievement score of transition readiness in youth/young adults with coRD and gender, primary diseases, age at the onset of primary disease, duration of primary disease, or age at the enrollment. We found that both achievement score of transition readiness in youth/young adults with coRD and that in parents/caregivers were significantly lower in subjects with overprotection of parents/caregivers. <Conclusion> Overprotection of parents/caregivers may be an obstructive factor for transition readiness in youth/young adults with childhood-onset rheumatic diseases and their parents/caregivers.

    Introduction : Methotrexate( MTX) is the only disease modifying anti-rheumatic drugs( DMARDs) that is approved for juvenile idiopathic arthritis( JIA) in Japan. Therefor, the patients who had an adverse event for MTX have been taken into consideration of using biological agents. Purpose : We evaluated retrospectively the association between dose of MTX, frequency of adverse events, and introduction of biological agents in articulated JIA. Results : Forty-six patients with JIA were included in this study. The mean age at evaluation was 17 years and mean duration from illness onset was 10 years. Adverse events were observed in 23 patients( 50%), and the most common symptom was nausea. The patients who experienced adverse events( n = 23) received significant higher dose of MTX compared to the patients who did not experienced adverse events( n = 22)( 2.6 vs. 7.4 mg/ m2/week ; p =0.0029), and moreover the patients having MTX tolerance received more biological agents than having MTX intolerance( 83 vs. 50% ; p =0.0029). Conclusion: Although MTX is an effective for the patients with JIA, the patients frequently experienced adverse events. There are no other DMARDs we could use instead of MTX in Japan. We expect that other DMARDs will be approved for treatment of JIA, even in consideration of medical economy and appropriate disease management.

    The present case report describes a 14-year-old girl with systemic lupus erythematosus( SLE). She presented with butterfly-shaped erythema, oral ulcers, joint pain, proteinuria, pericarditis, leukopenia, elevated anti-dsDNA-, anti-Sm-, and antiphospholipid antibodies, and low complement, and was antinuclear antibody-positive. As she had a cough and bloody sputum on admission, alveolar hemorrhage syndrome was suspected. Therefore, she underwent two courses of steroid pulse therapy, and her symptoms of SLE promptly improved. International Society of Nephrology class Ⅲ (A/C) lupus nephritis was diagnosed according to kidney biopsy results. Due to the possibility of diffuse alveolar hemorrhage, she underwent ovarian tissue cryopreservation to preserve her fertility and cyclophosphamide pulse therapy was initiated four days after. Young women with cancer undergo ovarian tissue cryopreservation when treated with alkylating agent; however, this is the second report of cryopreservation of ovarian tissue for SLE in Japan. SLE affects young women at a high rate; therefore, female patients with SLE should be presented with the option of ovarian tissue cryopreservation before cyclophosphamide pulse therapy.

    Patients with childhood-onset systemic lupus erythematosus (SLE) often follow a more acute and severe clinical course compared with those with adult-onset SLE. Herein, we report a case of refractory SLE. An 11-year-old boy was diagnosed with severe lupus nephritis (LN), classified as IV-S(A) on histology using the International Society of Nephrology/Renal Pathology Society classification. He was treated with methylprednisolone pulse therapy (MPT), mycophenolate mofetil (MMF), and intravenous cyclophosphamide for remission. Seven months after treatment initiation, the patient experienced a recurrence of SLE, associated with deteriorated renal function. He was retreated with MPT, MMF, tacrolimus, and hydroxychloroquine. A second renal biopsy was performed; he had progressed to class Ⅳ-G (A/C) on histology with either crescent formation or segmental sclerosis or both in all glomerulus. Therefore, we introduced immuno-adsorption plasmapheresis, as well as repeated rituximab treatment. It took approximately 10 months to achieve normal urinary findings after the recurrence, despite a persistently high level of serum anti-double-stranded DNA antibody. Male sex, childhood onset, and associated LN are adverse prognostic factors of SLE. Thus, remission induction in the early stage of the disease should include treatment with multi-target therapy, immuno-adsorption plasmapheresis and B-cell depletion in male patients with childhood-onset SLE complicated with severe LN.

    Juvenile dermatomyositis( JDM) is an autoimmune disease presenting with predominantly proximal muscle weakness and characteristic dermatological symptoms. Patients generally have a good prognosis, and the majority of cases are responsive to steroid therapy. However, a fulminant subtype is particularly dangerous, with rapid deterioration of muscle tissue and release of myoglobin into the bloodstream, causing significant myoglobinemia and myoglobinuria, which can trigger acute renal failure. An 8─year─old boy diagnosed with JDM by his previous physician had no symptomatic improvement following intravenous methylprednisolone (IVMP) and methotrexate (MTX). He was further diagnosed with steroid─resistant JDM, and referred to our hospital for further treatment. The boy was started on intravenous cyclophosphamide upon admission. Subsequent dramatic decline in muscle strength, severe muscle pain, and dysphagia led to a diagnosis of fulminant JDM. Tacrolimus (TAC) and intravenous immunoglobulin (IVIG) were added to his treatment regimen, but his condition still did not improve. Concerned about his risk of renal failure, we decided to perform therapeutic plasma exchange (TPE) to induce remission. Our efforts were successful. Our experience suggests that TPE in combination with immunosuppressants is an effective treatment for acute presentations of treatment─resistant fulminant JDM.

    Juvenile dermatomyositis (JDM) is a rare autoimmune disorder characterized by dermal and muscular symptoms and defined as dermatomyositis that develops under the age of 16. Its prognosis is not always benign especially if the intervention is delayed. Therefore, we should have high index of suspicion for JDM in children having prolonged dermal and muscular symptoms for early diagnosis of JDM. We encountered a 4-year-old girl with JDM who presented with butterfly rash and skin eruptions lasting for more than 3 months. She responded well to the intervention consisting of steroid and methotrexate. In order to clarify the clinical features for the diagnosis of JDM in early infancy, we reviewed the reported cases of JDM which developed younger than 5 years of age including ours. As a result, persistent dermal symptoms were observed dominantly, while signs and symptoms due to myositis were rare in patients with JDM younger than 5 years of age. Therefore, in infants with prolonged dermal signs and symptoms, we should suspect the existence of JDM behind and perform MRI to detect the myositis in infancy.

    Pyoderma gangrenosum (PG) is a sterile pyoderma that initially forms small pustules and papules predominantly on the lower extremities, and rapidly evolves to ulcers. It is often associated with inflammatory bowel disease, arthritis or vasculitis. A 2-year-old girl presented with a two-week history of fever, tonsillitis, mild abdominal pain and a skin ulcer on her left lower leg. Initially, a small pustule formed on her leg, for which oral antibiotics were not effective. Subsequently, the skin lesion ulcerated. The ulcer improved with cleaning and the application of an ointment (Sulfadiazine silver), but she showed pathergy and sterile abscesses developed on her finger and lips. Because of the absence of HLA-A26 and B51, major symptoms of Behçet’s disease( eg. genital ulcer or uveitis), and vasculitis, we diagnosed Sweet’s syndrome at the first medical examination. After starting prednisolone, all of her symptoms improved. However during the tapering of prednisolone, her symptoms, especially abdominal pain, recurred. Multiple ulcers on her colon were observed during gastrointestinal endoscopy, and we revised the diagnosis to intestinal Behçet’s disease. As the features of skin pathologies of Behçet’s disease, Sweet’s syndrome and PG are similar to each other, attention should be given to the changes in symptoms and diagnosis and treatment should be reviewed. 9:70-75

    We describe the case of linear scleroderma with arthritis of interphalangeal joints of hand as an initial symptom. An 8-year-old girl was referred to us with a 4-month history of swelling and arthralgia of right third metacarpophalangeal (MP) joint and a 3-month history of arthralgia of left second proximal interphalangeal joint. Laboratory examination showed no significant findings. Contrast magnetic resonance imaging (MRI) revealed peritendinitis around the left third MP joint with longitudinal enhancement of flexor tendon, bone marrow edema of the third metacarpal bone and peritendinitis around the right second PIP joint. Linear lesions of scleroderma became gradually clear several months later. The diagnosis of linear scleroderma was made. Cyclosporine was started and abnormal findings at the site of linear lesion on MRI were improved after 1 year treatment with cyclosporine. This patient presented diagnostic difficulties because she had no typical skin lesion of scleroderma. MRI might be useful to diagnose linear scleroderma. Patients with linear scleroderma with arthritis should be treated aggressively with immunosuppressants including cyclosporine to prevent the development of joint contracture leading to permanent dysability.
