RESUMO
Objective: To explore the clinical features and prognosis of children with histiocytic necrotizing lymphadenitis (HNL). Methods: The clinical data of 118 children with HNL diagnosed and treated in the Department of Rheumatology and Immunology of Children's Hospital, Capital Institute of Pediatrics from January 2014 to December 2021 were retrospectively analyzed. The clinical symptoms, laboratory examination, imaging examination, pathological findings, treatment and follow-up were analyzed. Results: Among the 118 patients, 69 were males and 49 were females. The age of onset was 10.0 (8.0, 12.0) years, ranging from 1.5 to 16.0 years. All the children had fever lymph node enlargement, blood system involvement in 74 cases (62.7%), skin injury in 39 cases (33.1%). The main manifestations of laboratory examination were increased erythrocyte sedimentation rate in 90 cases (76.3%), decreased hemoglobin in 58 cases (49.2%), decreased white blood cells in 54 cases (45.8%) and positive antinuclear antibody in 35 cases (29.7%). Ninety-seven cases (82.2%) underwent B-mode ultrasound of lymph nodes, showing nodular lesions with low echo in the neck; 22 cases (18.6%) underwent cervical X-ray and (or) CT; 7 cases (5.9%) underwent cervical magnetic resonance imaging. Lymph node biopsy was performed in all 118 cases, and the pathological results did not support malignant diseases such as lymphoma or Epstein-Barr virus infection, suggesting HNL. Fifty-seven cases (48.3%) recovered without treatment, 61 cases (51.7%) received oral steroid therapy, and 4 cases (3.4%) received indomethacin as anal stopper. The 118 cases were followed up for 4 (2, 6) years, ranging from 1 to 7 years, 87 cases (73.7%) had one onset and did not develop into other rheumatological diseases, and 24 cases (20.3%) had different degrees of recurrence, 7 cases (5.9%) had multiple system injuries, and all of the tested autoantibodies were positive for medium and high titers. All of them developed into other rheumatic immune diseases, among which 5 cases developed into systemic lupus erythematosus and 2 cases developed into Sjogren's syndrome; 7 cases were given oral steroid therapy, including 6 cases plus immunosuppressant and 2 cases receiving methylprednisolone 20 mg/kg shock therapy. Conclusions: The first-onset HNL portion is self-healing, hormone-sensitive and has a good prognosis. For HNL with repeated disease and multiple system injury, antinuclear antibody titer should be monitored during follow-up, and attention should be paid to the possibility of developing into other rheumatological diseases, with poor prognosis.

Objective: To summarize the clinical characteristics and treatments of chronic non-bacterial osteomyelitis with autoimmune hepatitis in children. Methods: A child who had chronic non-bacterial osteomyelitis with autoimmune hepatitis was admitted to the Department of Gastroenterology of the Children's Hospital Capital Institute of Pediatrics at April 2022. The clinical data was retrospectively analyzed. Using the keywords of "chronic non-bacterial osteomyelitis""autoimmune hepatitis" in Chinese and English, the literature from database establishment to December 2022 in CNKI, Wanfang, China Biomedical Literature Database and Pubmed was searched. Combined with this case, the clinical characteristics and treatment of chronic non-bacterial osteomyelitis combined with autoimmune hepatitis were analyzed. Results: A 5 years and 3 months girl was admitted to the Department of Gastroenterology of Children's Hospital, Capital Institute of Pediatrics for "transaminase elevated for 1 year and swelling of right maxillofacial area for half a year". The physical examinations at admission found a 4.0 cm × 4.0 cm swelling area with tenderness before the right ear, abdominal distention with visible abdominal wall vein, firm and enlarged liver (10.0 cm below the xiphoid and 4.5 cm below the right ribs), and splenomegaly (Line Ⅰ 10.0 cm, Line Ⅱ 11.5 cm, and Line Ⅲ 25.0 cm). There was no redness, swelling or restriction of the limbs. Laboratory examination found abnormal liver function with alanine aminotransferase 118 U/L, aspartate aminotransferase 227 U/L, γ-glutamyltransferase 360 U/L, and positive direct anti-human globulin test; immunology test found immunoglobulin G 41.60 g/L and a homogeneous type of antinuclear antibody of 1∶1 000; the autoimmune hepatitis antibody test found a positive anti-smooth muscle antibody (1∶100). Liver biopsy showed moderate interfacial inflammation and the patient was diagnosed with autoimmune hepatitis (International Autoimmune Hepatitis Group 19). The imaging findings showed extensive involvement of the bilateral mandible, while the right side was severe. There were expansile bone changes, thinning of the bone cortex, and significant swelling of the surrounding soft tissue in the mandibular body, mandibular angle, and mandibular ramus. After treatment of glucocorticoid, the swelling of the right maxillofacial region disappeared and the transaminase returned to normal. Only one case was reported before in English and none in Chinese. The two cases were both girls whose main clinical features were joint pain and swelling. The previous case started with pain in both knee joints, and developed liver injury during treatment while this case had liver injury as the initial clinical presentation. Besides, the affected sites and degrees of arthritis in the 2 cases were different. After glucocorticoid treatment, the clinical symptoms were alleviated, and transaminases returned to normal. Conclusions: Chronic non bacterial osteomyelitis may involve the liver and manifest as autoimmune hepatitis. Glucocorticoids therapy is effective.

Objective: To summarize the clinical, radiological characteristics, and prognosis of infectious sacroiliitis in children. Methods: A case-control study was conducted, including 12 cases of infectious sacroiliitis diagnosed in the Rheumatology and Immunology Department of the Children's Hospital affiliated with the Capital Institute of Pediatrics from June 2018 to June 2023. These cases comprised the case group. Concurrently, 28 cases of pediatric idiopathic arthritis involving the sacroiliac joint in the same department served as the control group. Basic patient information, clinical features, laboratory parameters, and clinical treatment outcomes for both groups were collected and analyzed. Independent sample t-tests and chi-squared tests were used for inter-group comparisons. Results: Among the 12 cases in the case group, there were 5 males and 7 females, with a disease duration of 0.8 (0.5, 1.2) months. Nine patients presented with fever, and 1 patient had limping gait. Human leukocyte antigen (HLA)-B27 positivity was observed in 1 case, and there was no family history of ankylosing spondylitis. In the control group of 28 cases, there were 19 males and 9 females, with a disease duration of 7.0 (3.0, 17.0) months. One patient (4%) had fever, and 14 cases (50%) exhibited limping gait. HLA-B27 positivity was found in 18 cases (64%), and 18 cases (64%) had a family history of ankylosing spondylitis. The case group had higher white blood cell count (WBC), neutrophil ratio, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, as well as a higher proportion of unilateral involvement on magnetic resonance imaging and bone destruction on CT compared to the control group ((11.1±6.2)×109 vs. (7.3±2.3)×109/L, 0.64±0.10 vs. 0.55±0.12, 72 (34, 86) vs. 18 (5, 41) mm/1 h, 24.6 (10.1, 67.3) mg/L vs. 3.6 (0.8, 15.0) mg/L, 11/12 vs. 36% (10/28), 9/12 vs. 11% (3/28), t=2.90, 3.07, Z=-2.94, -3.28, χ2=10.55, 16.53, all P<0.05). Conclusions: Pediatric infectious sacroiliitis often presents as unilateral involvement with a short disease history. Elevated WBC, CRP, and ESR, as well as a high rate of bone destruction, are also common characteristics.

Objective: To evaluate the efficacy and safety of intra-articular injection of adalimumab (ADA) in the treatment of refractory oligoarticular juvenile idiopathic arthritis (JIA). Methods: This was a retrospective study. Clinical data on age, gender, and symptoms of joint swelling and pain were collected from 11 children with refractory oligoarticular JIA involving only knee joints admitted to Department of Rheumatism and Immunology of Children's Hospital, Capital Institute of Pediatrics from November 2019 to October 2020. The physician and parent-child evaluation of disease activity, the number of active joints, and the level of erythrocyte sedimentation rate (ESR) at different treatment time points were analyzed at every 4-week observation point after drug administration, and the non-parametric Kruskal-Wallis test was used to compare the differences in clinical evaluation indicators and changes in laboratory tests at different treatment times. The follow-up period was 6 months. Results: Among the 11 children, 5 were boys and 6 were girls. The age was 3.0 (2.8) years. All 11 children had symptoms of joint swelling and pain as well as limitation of movement. After 3 intra-articular injections of ADA, the joint symptoms of 11 children were better than before treatment; the joint symptoms of 7 children disappeared completely, and no recurrence occurred during the 6-month follow-up period. At different treatment times, physician and parent-child evaluation of disease activity, a gradual decrease in the number of active joints in the children, ESR, and juvenile arthritis disease activity score with 27 joints were all statistically significant (χ2=53.99, 59.37, 32.87, 40.07, 54.00, all P<0.001).No significant adverse drug reactions were observed in any of the 11 children during treatment and follow-up. Conclusion: Intra-articular injection of ADA in the treatment of refractory oligoarticular JIA has a significant effect in controlling joint symptoms and is relatively safe.

Objective: To investigate the clinical characteristics of systemic juvenile idiopathic arthritis combined with coronary artery dilatation. Methods: A retrospective analysis was performed on the clinical data, including clinical manifestations, blood routine, inflammatory factors, echocardiography, vascular ultrasound and CT angiography, treatment and outcomes, etc, of 5 cases with systemic juvenile idiopathic arthritis combined with coronary artery dilation admitted to Department of Rheumatology in the affiliated Children's Hospital of Capital Institute of Pediatrics from May 2019 to June 2021. Results: There were 2 males and 3 females among 5 cases. The onset age ranged from 7 months to 4 years 7 months.The diagnostic time ranged from 1.5 months to 3.0 months.Four cases were diagnosed as atypical Kawasaki disease. Three cases showed unilateral coronary artery dilation.Two cases showed bilateral coronary artery dilation.Four cases developed multiple organ injuries.Three cases developed macrophage activation syndrome.Three cases developed lung injury.Two cases developed pericardial effusion.One case developed pulmonary hypertension.As for treatment, 3 cases treated with methylprednisolone pulse therapy and methotrexate combined with cyclosporine, improved after the final application of biological agents, and have stopped prednisone. The other 2 cases were treated with adequate oral prednisone and gradually reduced, and methotrexate was added at the same time, 1 case relapsed in the process of reduction. No other vascular involvement was found in 5 cases. Coronary artery dilation recovered completely after 1 to 3 months of treatment. Conclusions: Systemic juvenile idiopathic arthritis combined with coronary artery dilatation has the clinical characteristics of small onset age, long diagnostic time, prone to multiple organ injuries. Corticosteroids and conventional immunosuppressive agents are not sensitive, and biological agents should be used as soon as possible.The prognosis of coronary artery dilation is good after timely treatment.

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of autologous peripheral blood hematopoietic stem cell transplantation (auto-PBHSCT) and its therapeutic effect on refractory rheumatism among preschool children.</p><p><b>METHODS</b>Three boys with juvenile rheumatoid arthritis (JRA), juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM) respectively, 3 to 6 years old with the mean age of 5 years with 3.5 to 22 months course of disease with 14 months on average, received auto-PBHSCT. Their conditions were so severe that conventional therapy failed to control the diseases. The changes of both clinical manifestations and immunologic indexes were observed before and after transplantation with long term following up at specialty clinic of rheumatism.</p><p><b>RESULT</b>The time when neutrophil count >or= 0.5 x 10(9)/L in the 3 children was days +9, +13 and +11 respectively, that of platelet count >or= 20 x 10(9)/L was days +14, +18 and +13 respectively. The cellular immune function remained abnormal with CD4 cells at a low level and CD4/CD8 being inverted. As to the JDM child, the skin rash had disappeared and his muscle tone was improved to grade 5 within one month after the transplantation. The EMG and serum creatase level returned to normal and muscle MRI findings were improved greatly within 2 months after the transplantation. As to the JSLE child, skin rash and proteinuria had disappeared, MRI of brain showed that the pathological changes had been absorbed and EEG returned to normal 3 months after the transplantation, all the autoantibodies turned to negative within 8 months after transplantation. As to the JRA child, the arthritis had been improved remarkably within 3 weeks after auto-PBHSCT. There was no swelling of joints nor movement limitation 3 months post transplantation. The steroids and immunosuppressive drugs were discontinued post transplantation. Cushing syndrome disappeared. Their body heights increased by 10 to 15 cm in the past 18 months, and they all returned to school. There was no relapse during follow-up periods of 25 - 27 months.</p><p><b>CONCLUSION</b>The therapy with auto-PBHSCT for refractory rheumatism among preschool children was remarkably effective in a short-term, yet the safety and long-term effect still need to be further studied.</p>
