Thirty-six cases of necrotizing lymphadenitis--including 33 cases of unknown etiology, 1 typhoid lymphadenopathy, and 2 cases of suspicious lupus lymphadenopathy--were clinico-pathologically reviewed and analyzed with immunostaining for s-100 and lysozyme. All cases histologically showed architectural effacement by paracortical lesions composed of nuclear karyorrhexis and mononuclear cell proliferation. Immunohistochemical study revealed proliferation of lysozyme-positive macrophages in the necrotizing areas and an increase in the number of s-100-positive cells in the uninvolved paracortical areas. This observation suggests that necrotizing lymphadenitis may be a common morphologic expression of a T cell-mediated hyperimmune condition induced by diverse etiologies.

Between January 1986 and January 1989, 524 non-typhoid salmonella strains, of which 4 (0.8%) from urine, were isolated at the Microbiology Laboratory of Department of Biomedicine (University of Pisa). These strains were isolated from a man with systematic lupus erythematosus, from two little girls with structural defects of the lower urinary tract, and from a woman with ulcerous colitis. Except the last case, the others were associated with immunological or structural abnormalities that are thought to predispose to salmonella infections.

We report a case of well-documented typhoid fever in a 30-year-old woman with inactive systemic lupus erythematosus with asymptomatic lupus anticoagulant and high-titer anticardiolipin antibody (aCL). Despite prompt eradication of the Salmonella typhi obtained with appropriate antibiotic therapy, multiple organ system dysfunction occurred. The central nervous system was involved, with ischemic infarcts in the occipital lobes. High-dose corticosteroid therapy failed to improve the neurologic manifestations, which responded to repeated plasmapheresis. A sharp fall in aCL and anti-beta2-glycoprotein I antibody titers was recorded before the start of plasmapheresis. At the same time, IgM and IgG antibodies to Salmonella group O:9 lipopolysaccharide became detectable; the IgM antibodies disappeared within 4 months, whereas the IgG antibodies remained detectable during the next 13 months. Despite treatment with high-dose corticosteroids and cyclophosphamide, rapidly progressive glomerulonephritis developed, leading to chronic renal failure. There is convincing evidence of a link between the S. typhi infection and the ensuing catastrophic syndrome in this patient, probably precipitated by bacterial antigens.

Increased susceptibility to infection has long been observed among patients with systemic lupus erythematosus, and still represents a chief cause of morbidity and mortality in these patients. This is due in part to the severity of infection and to the difficulty of early diagnosis owing to the similarity between SLE flares and infection. Epidural infection is an uncommon condition, and a most rare condition caused by salmonella, which accounts for a broad spectrum of human illnesses from gastroenteritis and typhoid fever to the asymptomatic carrier state. We report the first case of epidural abscess caused by Salmonella enteritidis in a female with SLE with protean manifestations treated by intravenous antibiotics and surgery with full recovery of neurological symptoms, illustrating the importance of performing an early diagnosis and prompt treatment.
