Immunoepidemiology of post-Salmonella reactive arthritis in a cohort of women.

Following a foodborne outbreak of Salmonella dysentery in a group of 79 women and 4 men, 6 individuals were found to have reactive arthritis (ReA). None of the affected individuals had the classical genetic marker HLA B27 although 2 of the 6 had CREG antigens. IgA antibodies to the lipopolysaccharide of the causative organism, Salmonella heidelberg, were found to be elevated in those patients with active ReA compared to those with inactive ReA or those who had dysentery but did not develop ReA. The lymphocyte proliferative response to both PHA and the whole S. heidelberg organism was impaired in the patients with ReA (active or inactive) compared with the non-ReA patient controls. In this predominantly female outbreak of Salmonellosis, the development of ReA lacked an association with HLA class I antigens commonly recognized.

Interplay of microbe and major histocompatibility complex: a family study.

We describe a 24-year-old man who developed reactive arthritis (ReA) after a dysenteric illness caused by Salmonella hadar. Serologic tests suggested recent exposure of family members to Salmonella. All members of the family were HLA-B27 positive, but no other family member developed acute ReA, although 2 of them had clinical evidence of previously existing B27 associated arthritis.

Psoriatic arthritis and myopathy.

We describe a patient with psoriatic arthritis and a myopathy. The myopathy did not follow the time course of topical steroid treatment, nor did the patient display any features of hypercorticolism or local steroid excess. No evidence was found to support the diagnosis of polymyositis. Psoriatic myopathy is an uncommonly described condition. Steroid induced myopathy shares some nonspecific features with psoriatic myopathy, but can be differentiated by the clinical response to cessation of steroid therapy. Myalgia and 24 h urine creatine elevation are 2 features not previously described in association with psoriatic myopathy. The latter appears to correlate with muscle weakness and may be useful in following the course of this disease.

Erythema nodosum and non-Hodgkin's lymphoma.

We describe a case of erythema nodosum associated with non-Hodgkin's lymphoma. The course and resolution of the erythema nodosum correlated most closely with a breakdown and release of new antigen at the start of a new regimen of chemotherapy.

Eosinophilic fasciitis in a pair of siblings.

Two siblings, a 38-year-old woman and a 33-year-old man, developed eosinophilic fasciitis within a period of 6 months. They were found to have identical HLA-A, B, DR, and DQ antigens, raising the possibility of a genetic influence in the development of this disease. No common environmental factors close to the time of onset were identified; however, the possibility of a common, remote environmental factor cannot be discounted.

Internuclear ophthalmoplegia in giant cell arteritis.

Ophthalmoplegia from ischemia to peripheral ocular motor nerves or muscles may complicate the course of giant cell arteritis (GCA). Although brainstem ischemia is known to occur in GCA, internuclear ophthalmoplegia has not been described. Two cases of biopsy-proven GCA are described in which internuclear ophthalmoplegia resulted from brainstem ischemia. Embolization from thrombosed extradural segments of inflammed vertebral arteries, or arteritis of brainstem perforating vessels may account for brainstem infarction. Rapid tapering of steroids was temporally related to brainstem infarction in both cases.
