OBJECTIVES: To study the clinical characteristics of pediatric Behçet syndrome (BS). METHODS: A retrospective review was conducted on the medical records of children hospitalized in the Department of Pediatrics at the Second Hospital of Hebei Medical University between December 2014 and December 2024 who met diagnostic criteria for BS. RESULTS: Among 45 children with BS, 26 (58%) were male. Oral aphthous ulcers were the most common manifestation (43/45, 96%), followed by genital ulcers (23/45, 51%) and gastrointestinal involvement (18/45, 40%). Genital ulcers were more frequent in girls, whereas ocular involvement was more common in boys (P<0.05). The pathergy test was positive in 10 (22%), and HLA-B51 was positive in 13 (29%). Fecal calprotectin (FC) was elevated in 16 (36%); gastrointestinal involvement was more frequent in children with elevated FC than in those with normal FC (P<0.05). According to the respective criteria, 17 (38%) patients met the International Study Group criteria (1990), 33 (73%) met the International Criteria for Behçet Disease (2014), and 13 (29%) met the Pediatric Behçet Disease criteria (2015). CONCLUSIONS Pediatric BS shows marked clinical heterogeneity. HLA-B51 is associated with disease susceptibility.

Myelodysplastic syndromes (MDS) are clonal hematopoietic neoplasms characterized by chronic cytopenias and abnormal cell morphology, with a propensity of progressing to bone marrow failure or acute myeloid leukemia. Behçet's syndrome is a systemic vasculitis characterized by recurrent oral ulcers, skin lesions, and ocular inflammation. In recent years, an increasing number of clinical cases with coexistence of MDS and Behçet's syndrome have been reported, suggesting a potential pathological relationship between these conditions. Abnormal immune cell activation, dysregulated cytokine secretion, and cytogenetic alterations are thought to play critical roles in the pathogenesis of MDS combined with Behçet's syndrome. Currently, treatment strategies for MDS combined with Behçet's syndrome are primarily individualized and include immunosuppressive therapy, cytotoxic drug therapy, targeted therapy, and hematopoietic stem cell transplantation. However, due to the limited number of case reports and insufficient research on the underlying mechanisms, selecting appropriate treatment options remains challenging. This article reviews the pathogenesis and interrelationships of MDS combined with Behçet's syndrome and summarizes recent advancements in treatment strategies, providing a reference for clinical management and further researches on related mechanisms.

OBJECTIVE: To explore the clinical and genetic characteristics of a boy with X-linked familial Behcet-like autoinflammatory syndrome-2 (AIFBL2). METHODS: A boy who was admitted to Children's Hospital Affiliated to Zhengzhou University in December 2023 due to recurrent oral ulcers for 2 years, intermittent abdominal pain and fever for more than 1 year was selected as the study subject. Clinical data of the patient was collected. Whole exome sequencing (WES) was carried out, and candidate variant was verified by Sanger sequencing and bioinformatic analysis. A literature search was conducted in OMIM, PubMed, Wanfang Data Knowledge Service Platform, China Biomedical Literature Service System, and the VIP database using the keywords "ELF4 gene" "deficiency in ELF4, X-linked" "ELF4 deficiency" and "DEX" to identify recently published studies. This study was approved by the Medical Ethics Committee of the Children's Hospital Affiliated to Zhengzhou University (Ethics No.: 2023-H-K44). RESULTS: The patient, a 12-year-old male, presented with recurrent mouth ulcers, fever and abdominal pain. Lymphocyte subsets showed a significant decrease in NK cells. Abdominal CT showed thickening of local intestinal wall in the lower right abdomen. Colonoscopy revealed a solitary deep longitudinal ulcer in the ileocecal region. Genetic testing revealed a hemizygote missense variant c.687C>G, with his mother showing the same mutation at this locus. According to the guidelines of the American College of Medical Genetics and Genomics (ACMG), the variant was considered likely pathogenic (PP1+PP2+PM2_Supporting+PP3+PP4). Literature review has found 19 AIFBL2 patients including 1 patient from this study. Mouth ulcer, fever, rash and abdominal pain were the primary clinical manifestations, for which genetic testing is the main diagnostic method. CONCLUSION The hemizygote c.687C>G missense variant of the ELF4 gene probably underlay the AIFBL2 in this child, which has provided a basis for his clinical diagnosis and genetic counseling.

Objective: To retrospectively investigate the clinical data, radiological characteristics, treatment, and outcome of patients with parenchymal neuro-Behcet's disease (P-NBD) with particular emphasis on dizziness. Methods: This was a cross-sectional study of clinical data from 25 patients with a confirmed diagnosis of P-NBD who were admitted to the Department of Neurology of the First Medical Center of Chinese People's Liberation Army General Hospital between 2010 and 2022. The median age of the population was 37 years (range: 17-85 years). Clinical data were retrospectively analyzed, including gender, age of onset, disease duration, clinical manifestations, serum immune indicators, cerebrospinal fluid (CSF) routine biochemical and cytokine levels, cranial and spinal magnetic resonance imaging (MRI) findings, treatment, and outcome. Results: The majority of patients were male (16 cases; 64.0%), the mean age of onset was (28±14) (range: 4-58 years), and the disease course was acute or subacute. Fever was the most common clinical presentation, and the complaint of dizziness was not uncommon (8/25 patients). Analysis of serum immune indices, including complement (C3 and C4), erythrocyte sedimentation rate, interleukin-1 (IL-1), IL-6, IL-8 and tumor necrotic factor-alpha were abnormal in 80.0% of patients (20/25). Most of the 16/25 patients who underwent lumbar puncture tests had normal intracranial pressure and increased CSF white cell count and protein [median values were 44 (15-380) ×10⁶/L and 0.73 (0.49-2.81) g/L, respectively]. Of the five patients who underwent CSF cytokine tests, four patients had abnormal results; of these, an elevated level of IL-6 was most common, followed by IL-1 and IL-8. The most common site of involvement in cranial MRI was the brainstem and basal ganglia (60.0% respectively), followed by white matter (48.0%) and the cortex (44.0%). Nine cases (36.0%) showed lesions with enhancement and six cases (24.0%) showed mass-like lesions. Three patients (12.0%) patients had lesions in the spinal cord, most frequently in the thoracic cord. All patients received immunological intervention therapy; during follow up, the majority had a favorable outcome. Conclusions: P-NBD is an autoimmune disease with multiple system involvement and diverse clinical manifestations. The symptom of dizziness is not uncommon and can be easily ignored. Early treatment with immunotherapy is important and can improve the outcome of these patients.

Behçet's disease (BD) is a systemic vasculitis characterized by recurrent acute vascular inflammation. There is currently limited epidemiological data in Southeast Asia. We discuss a 26-year-old woman who came to our institution for recurrent vulvar abscesses for a year. Physical examination showed labial, tongue, and vulvar ulcers. Pathergy test was negative and biopsy done were unremarkable . We diagnosed her clinically as a case of Behçet’s disease. We started her on colchicine 0.6 mg once daily and educated her on skin, oral, and perineal hygiene. On follow-up after one month, she noted resolution of her lesions. However, symptoms recurred in the last three months after discontinuing treatment. We used telemedicine to communicate due to the COVID-19 pandemic and lockdown, advising her to continue her medication. Timely diagnosis is essential in order to provide symptomatic relief and enhance patient education.

OBJECTIVE: This study explored the correlations between the use of complementary and integrative therapies (CITs) and symptoms among Turkish patients with familial Mediterranean fever (FMF). METHODS: This is a cross-sectional and descriptive study. The study was conducted with 1119 FMF patients who were registered to the social networking site for Behcet's and the FMF Patients Association (Befemder) in Turkey, between January 2018 and February 2019. Data were collected using an online survey, for which a three-part questionnaire was created using a Google form. Descriptive statistics, chi-square test and logistic regression analysis were used to analyze the data. RESULTS: It was determined that 53.2% of the individuals who participated in the research used various forms of CITs and that 32.8% used vitamin and mineral supplements (calcium, iron, and vitamin B12, C and D), 25.0% used nutritional supplements (fish oil and honey), and 24.6% used oral herbs (ginger, turmeric, green tea and rosemary) and mind-body methods (relaxation, respiration exercise and meditation). It was determined that the percentage of participants that used CITs was higher among women (odds ratio [OR] = 1.825; 95% confidence interval [CI] 1.421-2.344), those with joint pain (OR = 1.385; 95% CI 1.047-1.832), those with difficulty breathing (OR = 1.323; 95% CI 1.031-1.697), those with gastrointestinal symptoms (OR = 1.405; 95% CI 1.089-1.814) and those who had a family member with FMF (OR = 1.437; 95% CI 1.115-1.851). CONCLUSION More than half of the individuals used at least one type of CIT for symptom control.
