Safety and efficacy of intra-articular injections of a combination of hyaluronic acid and mannitol (HAnOX-M) in patients with symptomatic knee osteoarthritis: Results of a double-blind, controlled, multicenter, randomized trial.

Background: To compare both safety and efficacy of a novel intra-articular viscosupplement made of intermediate molecular weight (MW) hyaluronic acid (HA) mixed with high concentration of mannitol with a marketed high MW HA, in patients with knee osteoarthritis (OA).

Methods: Patients with symptomatic knee OA, with radiological OARSI grades 1 to 3, were enrolled in a controlled, double-blind, parallel-group, non-inferiority trial. They were randomized to receive three intra-articular injections, at weekly intervals, of either HAnOX-M made of a combination of HA (MW one to 1.

Exposure to abatacept or rituximab in the first trimester of pregnancy in three women with autoimmune diseases.

The use of biological therapies for treating autoimmune diseases is increasing. These therapies are sometimes administered to pregnant women as part of a planned therapeutic regimen or to women with unexpected or unplanned pregnancies. The safety of biological therapies in this setting is a major issue.

Skeletal recovery from hepatitis C-associated osteosclerosis (HCAO) following antiviral treatment.

Hepatitis C-associated osteosclerosis (HCAO) is characterized by increased bone mass following hepatitis C infection. We report here a case of HCAO that lasted 8 years before the patient received antiviral hepatitis treatment. Seven years after the antiviral treatment, the evolution of radiographs and densitometry showed skeletal recovery of osteosclerosis.

Jessner-Kanof disease induced by leflunomide: a dermal variant of cutaneous lupus?

Leflunomide can have adverse effects, but cases of subacute cutaneous lupus have more rarely been described. This drug, through its immunomodulatory effect, can favor the appearance of a Th2 lymphocyte immune response inducing lupus. A recent study has suggested that Jessner-Kanof disease (JKD) could be a dermal form of lupus.
