Rheumatic pneumonitis.

Successful reintroduction of methotrexate after pneumonitis in two patients with rheumatoid arthritis.

Two patients are described with severe and progressive rheumatoid arthritis in whom methotrexate was reintroduced despite previous methotrexate related pneumonitis. In both patients a marked improvement in disease control occurred without a recurrence of the pneumonitis.

Acute systemic lupus erythematosus with fatal pneumonitis and disseminated intravascular coagulation.

We reported the case of a 40-year-old female with acute onset of systemic lupus erythematosus, followed rapidly by the development of fatal pneumonitis and disseminated intravascular coagulation. The likely relationship between these events and the therapeutic options are discussed.

Title: Evidence for HSV-1-induced pneumonitis in patients under standard immunosuppressive therapy for rheumatic and vasculitic autoimmune disease

Life threatening acute pneumonitis during low dose methotrexate treatment for rheumatoid arthritis: a case report and review of the literature.

A patient is described with definite rheumatoid arthritis (RA) who developed life threatening acute pneumonitis after receiving a total dose of only 12.5 mg methotrexate (MTX). This complication has been previously described, but this is probably the lowest reported dose before development of pneumonitis in a patient with RA. The possible significance of this case is discussed in the light of r...
