Severe Leptospira interrogans serovar Icterohaemorrhagiae infection with hepato-renal-pulmonary involvement treated with corticosteroids

As immune mechanisms probably play a crucial role in advanced leptospirosis with presumed pulmonary hemorrhages, patients might benefit from corticosteroids or other immunosuppressive agents beside antibiotics.
