The case is reported of a patient who developed an acute arthropathy, which was initially diagnosed as acute septic arthritis. The true diagnosis of rat bite fever due to Streptobacillus moniliformis was delayed because of difficulty in growing the organism, which has fastidious growth requirements. The patient had no history of rat bite, which is the usual form of transmission of this disease.
Four cases of post-yersinial reactive arthritis are described. All patients presented with an acute lower limb arthropathy with features of an associated enthesopathy. Two patients had restriction of axial skeletal movements. Systemic features were prominent in three, including weight loss and malaise. Mean age of onset was 34 years. Three patients gave a history of antecedent diarrhoea within the previous month. Three patients had raised titres to Y enterocolitica type 0:3 (ranging from 1 in 320 to 1 in 2560) and one had raised titres to Y pseudotuberculosis type 2 at 1 in 640. Two of the three patients with Y enterocolitica reactive arthritis ran a chronic course with low grade arthropathy of lower limbs and back stiffness. One patient developed radiological sacroiliitis at two years, and two patients had an increased sacroiliac index, though x rays of the sacroiliac joints were normal. The patient with Y pseudotuberculosis reactive arthritis had a self limiting disease with spontaneous resolution over six months.
The concentration of IgA and titre of IgA antibodies to several Gram-negative bacteria were measured in the serum and parotid saliva of patients with AS and normal tissue-typed individuals. Salivary IgA and antibody levels in the patients were identical with the control population. The serum antibody level against Yersinia enterocolica 0:3 was slightly raised in patients but there was no difference in the reactions to Klebsiella oxytoca strain MX100 or Escherichia coli 0111.B4. The serum IgA level was elevated in patients with AS, irrespective of HLA B27. We conclude that this approach is unlikely to provide convincing evidence of a link between Gram-negative bacteria and ankylosing spondylitis.
A 49 year old man with rheumatoid arthritis developed a proliferative glomerulonephritis with progressive renal impairment during treatment with D-penicillamine. His renal function continued to deteriorate after the drug was stopped but improved after treatment with corticosteroids and azathioprine.
Although recurrent rheumatic fever in adults is uncommon and the recurrence rate declines with age and with the interval from the attack, we describe a patient who has had four attacks of rheumatic fever, two in childhood and two in adult life.
