Article Abstract
Hemophagocytic syndrome is a key point in the pathogenesis of severe forms of multisystem inflammatory syndrome associated with COVID-19 in children (MIS-C). The factors associated with hemophagocytosis in patients with MIS-C were assessed in the present study of 94 boys and 64 girls ranging in age from 4 months to 17 years, each of whose HScore was calculated. In accordance with a previous analysis, patients with HScore ≤ 91 ( = 79) and HScore > 91 ( = 79) were compared. Patients with HScore > 91 had a higher frequency of symptoms such as cervical lymphadenopathy, dry cracked lips, bright mucous, erythema/swelling of hands and feet, peeling of fingers, edematous syndrome, hepatomegaly, splenomegaly, and hypotension/shock. They also had a higher erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and D-dimer levels, and a tendency to anemia, thrombocytopenia, and hypofibrinogenemia. They more often needed acetylsalicylic acid and biological treatment and were admitted to ICU in 70.9% of cases. Conclusion: The following signs of severe MIS-C were associated with HScore > 91: myocardial involvement, pericarditis, hypotension/shock, and ICU admission.

Department of Dermatology, Baylor College of Medicine, Houston, Texas.
Background: Little is known about the dermatologic manifestations of multisystem inflammatory syndrome in children (MIS-C) in children and adolescents.
Objective: We sought to describe the demographic background, key clinical features, and the clinical consequences of developing rash manifestations in MIS-C patients at Texas Children's Hospital.
Methods: Descriptive retrospective cohort study of 290 hospitalized eligible patients between May 2020 and April 2022.
Behçet's disease and factor V Leiden: A thrombogenic synergy causing budd-chiari syndrome.

Department of Internal Medicine, An Najah National University Hospital, Nablus, Palestine.
Behçet's Disease (BD) is a multisystem inflammatory disorder that can lead to severe vascular complications, including Budd-Chiari Syndrome (BCS), a rare but life-threatening condition characterized by hepatic vein obstruction. The co-occurrence of BD and inherited thrombophilia, such as Factor V Leiden mutation, significantly increases the risk of thrombosis, complicating the clinical management of affected individuals. In this case, a 16-year-old female initially presented with nonspecific symptoms of generalized fatigue and bone pain, which later progressed to abdominal distension and significant hepatosplenomegaly.

Background: As a master immune system regulator, transforming growth factor β1 (TGF-β1) is closely linked to the complicated pathophysiology and development of systemic sclerosis (SSc), a multisystem fibrotic disease.
Objective: We aim to evaluate the transcriptional levels of TGF-β1 mRNA in PBMCs, assess the TGF-β1 serum levels of SSc patients, and compare them with those of healthy subjects.
Methods: PBMCs were isolated from whole blood of 50 SSc patients and in 30 healthy controls.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a liver disease that is strongly associated with chronic low-grade inflammation. Stage 3 of MASLD is characterized by excessive formation of connective tissues, commonly referred to as liver fibrosis. Although numerous inflammatory markers have been identified and extensively studied, including the tumor necrosis factor-α and interleukin-6 have been studied [Byrne CD, Targher G.

This case report presents the management of a 25-year-old woman with refractory hemophagocytic lymphohistiocytosis (HLH) secondary to adult-onset Still's disease. Despite initial treatment with corticosteroids and biologic therapies, including anakinra and tocilizumab, her condition continued to deteriorate, necessitating intensive care unit admission. Following multidisciplinary consultation, ruxolitinib therapy, a Janus kinase (JAK) inhibitor targeting hyperinflammation, was initiated.
