A case of fluminant septic shock due to Streptococcus agalactiae in a patient with MPO-ANCA related glomerulonephritis

Abstract

Recently group A Streptococcus toxic shock like syndrome (TSLS) has been reported, but as for group B streptococcus (S. agalactiae) infection, there have been little documentation in the literature. We report a case of fluminant septic shock due to Streptococcus agalactiae (S. agalactiae). A 72-year-old male was admitted to our hospital because of general fatigue and azotemia. He was diagnosed as having MPO-ANCA related glomerulonephritis and treated with steroid therapy. Gradually he was doing well. On the 228th hospital day, he suddenly had tachypnea, transient conscious disturbance, and profound hypotension. About 16 hours later, he died despite intensive treatment. S. agalactiae was isolated from the blood. Autopsy revealed bilateral bronchopneumonia and shock liver. To our knowledge, this is the first report of septic shock caused by S. agalactiae.
