Objective: To characterize the role of interleukin-1β (IL-1β) and microvascular endothelial cells (MVECs) in the generation of alternatively activated macrophages in the skin, and to explore their role in the development of skin fibrosis in patients with systemic sclerosis (SSc; scleroderma).

Methods: Conditioned medium prepared with MVECs purified from the skin of healthy donors and the skin of SSc patients was used to generate monocyte-derived macrophages. Flow cytometry, multiplex protein assessment, real-time quantitative polymerase chain reaction, and tissue immunofluorescence were used to characterize MVEC-induced polarization of alternatively activated macrophages.

Systemic sclerosis (SSc) is a rare autoimmune connective tissue disease characterized by a microangiopathy and fibrosis of the skin and internal organs. No treatment has been proved to be efficient in case of early or advanced SSc to prevent or reduce fibrosis. There are strong arguments for a key role of topo-I in the pathogenesis of diffuse SSc.

Introduction: Co-stimulatory molecule cytotoxic T-lymphocyte antigen-4 (CTLA-4) inhibits T-cell activation. Clinically, CTLA-4 has been targeted in opposite ways: its blockade enhances antitumor immunity in the field of oncology, whereas CTLA-4 agonists such as abatacept are used for the treatment of immuno-inflammatory diseases as rheumatoid arthritis (RA).

Observation: We herein report the case of a 69-year-old man with a history of severe RA successfully treated with abatacept, who showed unusually rapid progression of undifferentiated multi-metastatic carcinoma.

Background: Combination therapy with hydroxychloroquine and darunavir/ritonavir or lopinavir/ritonavir has been suggested as an approach to improve the outcome of patients with moderate/severe COVID-19 infection.

Objectives: To examine the safety of combination therapy with hydroxychloroquine and darunavir/ritonavir or lopinavir/ritonavir.

Methods: This was an observational cohort study of patients hospitalized for COVID-19 pneumonia treated with hydroxychloroquine and darunavir/ritonavir or lopinavir/ritonavir.

Philadelphia-negative myeloproliferative neoplasms (MPNs) greatly increase the risk of maternal and fetal complications during pregnancy. Currently, international agreements regarding the management of these women are lacking. Our study aimed to assess the current management and outcomes of MPN pregnancies in a French cohort.

Background: Although peripheral nervous system involvement is common in eosinophilic granulomatosis with polyangiitis (EGPA), central nervous system (CNS) manifestations are poorly described. This study aimed to describe CNS involvement in EGPA.

Patients And Methods: This retrospective, observational, multicenter study included patients with EGPA and CNS involvement affecting cranial nerves, brain and/or spinal cord.
