Antibiotic-induced endotoxemia in a patient with endogenous endophthalmitis

Abstract

Purpose: The aim of the study is to describe a case of suspected endotoxin-induced uveitis associated with septic endogenous endophthalmitis followed by antibiotic-induced endotoxemia. Methods: The human leukocyte antigen (HLA) typing of peripheral leukocytes was studied by lymphocytotoxicity technique. Histological and immunohistochemical studies of paraffin embedded specimen were conducted. Results: Findings of HLA typing revealed positive reaction for B 51, Cw 3, DR 8, DR 11, DQ 3. The vitreous body of an eviscerated eye was occupied by the non-specific granulomatous tissue, composed of fibroblast, plasma cells, and Sudan black staining positive foamy cells, including melaniferous phagocytes, identified as CD 68 positive macrophage. Conclusion: It is suggested that antibiotic-induced endotoxemia of a patient with septic endogenous endophthalmitis produced endotoxin-induced uveitis under an upregulation of HLA and endotoxin activated macrophages may release cytokines, followed by fibrin formation and subsequent granuloma.
