[Anti-fibrinogen antibody detected in a patient with systemic lupus erythematosus and disseminated intravascular coagulation].
A 22-year-old woman was admitted to our hospital with fever, generalized lymphadenopathy, and pancytopenia in February 1995. She was diagnosed as having systemic lupus erythematosus (SLE) based on positivity for anti-nuclear antibody, and polyarthritis among other findings. A diagnosis of disseminated intravascular coagulation (DIC) was made based on the increase of FDP and other data (DIC score: 7). We also detected an anti-fibrinogen antibody. Lymph node biopsy revealed subacute necrotizing inflammation and there were on signs of the hemophagocytic phenomenon in bone marrow. The DIC score improved and the anti-fibrinogen antibody disappeared in association with the response of SLE to prednisolone therapy. The onset of SLE associated with DIC has never been reported before, as far as we could determine. The mechanism of DIC associated with SLE may be related to endothelial damage caused by immune complexes.
