The changing pattern of hemolytic streptococcal gangrene.

We reviewed nine cases in which either limg-threatening or life-threatening complications developed due to streptococcal infection. Our findings indicate important changes in the pattern of this fulminating illness since its original description in 1924. A higher mortality reflects increased longevity with a greater frequency of impaired host resistance and degenerative diseases involving vital organs. Initial symptoms and signs often mimic acute thrombophlebitis, acute arthritis, deep soft-tissue trauma, or acute vascular occlusion. The emergence of multiple organ failure and serious coagulation disorders are a challenge to current therapy. A diagnostic algorithm was developed to aid in the early diagnosis and management of this life-threatening infection.
