TET1 Regulates Skeletal Stem-Cell Mediated Cartilage Regeneration

Akshay Pandey, Malachia Hoover, Mamta Singla, Yudhishtar Bedi, Hunter Storaci, Stuart B. Goodman, Charles Chan, Nidhi Bhutani

Summary: This study investigates how the DNA hydroxymethylase Tet1 regulates the function of adult skeletal stem cells (SSCs) in osteoarthritis (OA). It was found that loss of Tet1 expands the SSC pool and enhances their chondrogenic potential. Inhibiting Tet1 also enhances chondrogenesis in human SSCs and chondroprogenitors. Furthermore, the use of melatonin, a hormone, can mimic the inhibition ability of Tet1 and improve cartilage health.

Adalimumab Effectively Decreases Inflammation Downstream of TNFα Signaling in Synoviocytes from Extended Oligoarticular Juvenile Idiopathic Arthritis

Megan M. Simonds, Samuel T. Freer, Lina Al-Jaberi, AnneMarie C. Brescia

Summary: This study examines the effects of inhibiting TNF alpha signaling with adalimumab on fibroblast-like synoviocytes (FLS) isolated from synovial fluid of patients with juvenile idiopathic arthritis (JIA). The results suggest that adalimumab can reduce inflammation in FLS associated with TNF alpha.

Neuro-Behçet's disease with atypical subcortical nodular lesions: A case report and treatment approach

Kiyomi Yoshimoto, Tadanao Kobayashi, Hidetoshi Matsuoka, Nobushiro Nishimura, Hiromasa Kawashima, Ryo Yoneima, Emiko Tsushima, Shiro Ono, Kenji Nishio

Summary: This article reports a rare case of Neuro-Behcet's disease (NB) presenting with multiple subcortical nodular brain lesions but without involvement of the brainstem, thalamus, or basal ganglia. The diagnostic challenge of distinguishing between NB and tuberculosis based on imaging alone is highlighted, and the potential efficacy of high-dose steroid therapy in steroid-resistant NB with subcortical nodular brain lesions is demonstrated.

Long-Term Efficacy and Safety of Canakinumab in Patients With Tumor Necrosis Factor Receptor-Associated Periodic Syndrome: Results From a Phase III Trial

Marco Gattorno, Laura Obici, Inmaculada Calvo Penades, Tilmann Kallinich, Susanne Benseler, Elise Dekker, Jeremy Levy, Fabrizio De Benedetti, Helen Lachmann

Summary: This study assessed the efficacy, safety, and tolerability of canakinumab in TRAPS patients during a 72-week long-term, open-label extension. The results showed that long-term canakinumab treatment effectively controlled disease activity and reduced flare incidence in TRAPS patients. No new safety concerns were identified.

Use of transient elastography to assess hepatic steatosis and fibrosis in patients with juvenile idiopathic arthritis during methotrexate treatment

Summary: Hepatic steatosis is common among patients with juvenile idiopathic arthritis (JIA) receiving methotrexate treatment, but none had transient elastography-defined hepatic fibrosis. Overweight/obese JIA adolescents and patients with a high cumulative dose of methotrexate are at risk for hepatic steatosis.

Real-world safety and effectiveness of mepolizumab for patients with eosinophilic granulomatosis with polyangiitis in Japan: A 48-week interim analysis of the MARS study

Tomonori Ishii, Hideaki Kunishige, Tamami Kobayashi, Etsuko Hayashi, Masaki Komatsubara, Takeo Ishii, Rafael Alfonso-Cristancho, Jun Tamaoki, Peter Howarth

Summary: The study aims to evaluate the long-term safety and effectiveness of mepolizumab for eosinophilic granulomatosis with polyangiitis (EGPA) in Japan. The results show that mepolizumab treatment for 144 weeks led to a significant reduction in oral corticosteroid dose and improvement in clinical symptoms. The treatment demonstrated good safety profile and improved disease control among EGPA patients.

Immunohistochemical expression of perforin in adult systemic lupus erythematosus associated macrophage activation syndrome: Clinicohematological correlation and literature review

Summary: This study aimed to investigate the immunohistomorphological characteristics of bone marrow in adult SLE-MAS patients. The results showed that MAS was more common in patients who had prior immunosuppressive therapy, involvement of three or more systems, lower fibrinogen, increased triglyceride, and increased bone marrow hemophagocytosis. Fibrinogen, hemophagocytosis score, and MAS probability score were useful in discriminating between MAS and non-MAS patients.

Calcinosis in Juvenile Dermatomyositis-Epidemiology, Pathogenesis, Clinical Features, and Treatment: A Systematic Review

Jucier Goncalves Junior, Samuel Katsuyuki Shinjo

Summary: Calcinosis is common in female children with around five years of age and three years of disease duration. The pathogenesis involves interleukin 1 and 6, tumor necrosis factor alpha, and innate immunity dysregulation. Treatment with anti-NXP-2, anti-MDA-5, and anti-Mi-2 autoantibodies remains controversial, and further studies are needed to evaluate treatment protocols.

Summary: In an international real-world RA population, treatment discontinuations for adverse events were compared among second-line therapies including JAKi, TNFi, and other mode of action biologicals. While overall JAKi were not associated with more treatment discontinuations for adverse events, subgroup analyses revealed varying patterns with specific JAKi drugs like tofacitinib.
