Ninety-three patients with acute rheumatic fever and 195 patients with acute glomerulonephritis were observed in Trinidad during an outbreak of scabies with a high incidence of secondary streptococcal infections. Clinical and laboratory manifestations of ARF were the same as those seen in temperate zones, except that antistreptolysin O titers were less(More)
Serum immunoglobulin A (IgA) was markedly increased in 80% of 50 patients with acute rheumatic fever in Trinidad in contrast to 20% of 63 patients with acute glomerulonephritis, whereas serum IgG was increased in nearly all of both groups. Since total antibody to M-associated protein (MAP) (assessed by complement fixation) is the only antibody as yet(More)
A newly available dried concentrate of antihemophilic factor (Profilate, Abbott Laboratories) was compared with standard, blood-bank prepared cryoprecipitate in the control of bleeding in a patient with von Willebrand's disease. Profilate effectively raised plasma levels of factor VIII but produced only half the expected increase in plasma ristocetin(More)
We examined the hypothesis that streptococcal neuraminidase may alter host serum immunoglobulin G so that autoantibodies are formed which lead to immune complexes and acute glomerulonephritis. We confirmed the observation that T-type 4 and T-type 12 streptococci (both associated with acute glomerulonephritis) are the most likely of many types studied to(More)
To determine the incidence of chronic nephritis after poststreptococcal acute glomerulonephritis in Trinidad, 760 patients (41 adult) were examined two to six years after recovery from the illness, 344 being studied twice (four and six years). Only 1.8 per cent had persistent urine abnormalities on their last follow-up examination, and another 8.0 per cent(More)
Renal biopsies obtained from four adolescent girls who developed symptomatic thrombocytopenia with serologic evidence of systemic lupus erythematosus, without clinical signs of renal involvement, showed glomerular disease by electron and immunofluorescent microscopy with light microscopic changes in two cases. Subsequently, three of the patients developed(More)
