Serum opsonic activity for E. coli 075, conversion of C3 by inulin, total hemolytic complement (CH(50)), levels of native C3, factor B, C3b inactivator (KAF), properdin (P), and immunoglobulins (Ig) were determined in 14 patients with burns involving 13% to 91% body surface during 6 to 8 weeks postburn. In the 12 uninfected patients, levels of IgG and IgA were reduced during the first 10 days postburn, and decreased concentrations of P and IgM were demonstrated from three to 6 weeks postburn. C3 conversion was reduced from 10 days to 6 weeks postburn. Levels of C3, factor B, and KAF were normal or elevated for the entire study period. No difference in the occurrence of humoral abnormalities was noted in patients with burns caused by flame, immersion scald, or acid contact. Reduction in C3 conversion and P concentration were the only abnormalities which correlated with increasing burn size. Bacteremia and/or fungemia was documented in the other two patients. In one of these patients, reduction in CH(50) occurred during septicemia due to S. aureus, and in the other, reduction in all measurements of complement was associated with candidemia and Pseudomonas septicemia and occurred prior to the development of shock. Serum opsonic activity was only reduced significantly during sepsis, suggesting that this abnormality occurred as a result rather than a cause of infection. These results indicate that consumption of components of the classical and/or alternative pathways of complement activation may be an important mechanism by which infection is perpetuated in the burn patient. They also emphasize the importance of the clinical management of the burn patient in preventing the development of septic complications.

We encountered six patients with ecthyma gangrenosum due to Pseudomonas aeruginosa who, uncharacteristically, had no evidence of bacteremia prior to the institution of antibiotic therapy. Seven similar cases have previously been reported in the English-language medical literature. These 13 patients resembled those with classic ecthyma gangrenosum accompanied by Pseudomonas septicemia in being immunocompromised and neutropenic and having skin lesions at similar sites. The most striking difference between these two groups of patients was a significantly lower mortality rate for the nonbacteremic patients. These findings suggest that ecthyma gangrenosum can occur as a primary skin lesion in the absence of bacteremia. Patients with this particular subtype of infection appear to have a better prognosis than those having a preceding bacteremia.

Ecthyma gangrenosum (EG) is a recognized cutaneous infection commonly associated with Pseudomonas aeruginosa bacteremia. It typically occurs in patients who are septic and severely immunocompromised. Clinical presentation characteristically begins as an erythematous or hemorrhagic vesicle or bulla, which evolves into a necrotic ulcer with eschar and surrounding erythema. This was first described in association with Pseudomonas septicemia by Barker in 1897 and was later given the name "ecthyma gangrenosum" by Hitschmann and Kreibich.
