Multiple vasculopathies and hepatitis B in a family.

A unique kindred with an unusual high incidence of serological markers of past or present hepatitis B infection was studied. None of eight relatives had clinical or chemical evidence of hepatitis and all were negative for IgM anti-hepatitis A, but four sisters, each with at least one hepatitis B marker, had features of rheumatic disorders. The index patient had polyarteritis nodosa, two sisters had Raynaud's disease, and the fourth and unclassifiable non-inflammatory polyarthralgia. A daughter of one sister with Raynaud's developed the aortic arch syndrome. There was no segregation of HLA-A, -B and -C alleles with hepatitis B infection. The intrafamilial occurrence of B virus infection and multiple vasculopathies suggests a wider role of this virus in inflammatory vessel diseases.

Rheumatoid disease without arthritis.

A middle-aged man developed multiple subcutaneous rheumatoid granulomata, high titer of rheumatoid factor, diffuse interstitial pulmonary fibrosis and digital clubbing in the absence of clinicoradiological evidence of synovial disease. This patient supports the concept of rheumatoid disease without arthritis.

The effect of allopurinol on oxypurine excretion in xanthinuria.

In a patient with xanthine urolithiasis secondary to hereditary xanthinuria (xanthine oxidase deficiency), allopurinol administration resulted in a 20 per cent increase in oxypurine excretion and an elevation of the urinary xanthine/hypoxanthine ratio from 4.08 to 6.53. The rise in this ratio suggests that residual xanthine oxidase activity may have been present. It is possible that the excessive re-utilization of hypoxanthine and xanthine in this disease prevents the allopurinol-induced inhibition of de novo purine biosynthesis that is seen in normal subjects.

Destructive monarthritis and granulomatous synovitis as the presenting manifestations of Crohn's disease.

A twenty-two-year-old woman and a fourteen-year-old boy with Crohn's disease presented with progressive monarticular arthritis with radiologic evidence of altered articular cartilage and subchondral bone. In one individual, granulomatous inflammation of the synovium was demonstrated. Intestinal symptoms were not prominent. In both individuals, the development of the monarthritis led to the discovery of the underlying inflammatory bowel disease.
