Comparison of tolmetin sodium and aspirin in the treatment of juvenile rheumatoid arthritis.

The Pediatric Rheumatology Collaborative Study Group was established in 1973 to undertake systematic trials of new drugs in the treatment of juvenile rheumatoid arthritis. The first drug evaluated was tolmetin (1-methyl-5-p-toluoylpyrrole-2 acetic acid), a new nonsteroid anti-inflammatory agent. A four-week open trial with 30 patients and a subsequent 12-week double-blind trial against aspirin with 107 patients were conducted. Tolmetin and aspirin had equal anti-inflammatory and analgesic effects in the treatment of JRA. Elevations of transaminase values attributed to aspirin were not found with tolmetin. Adverse effects accompanying administration of tolmetin did not appear to be of major clinical significance.

Juvenile rheumatoid arthritis.

Juvenile rheumatoid arthritis is a diverse group of diseases that includes systemic-onset, polyarticular, and pauciarticular types. Appreciation of the different types and their hallmarks is particularly important to accurate diagnosis, which is determined by exclusion of other known disease entities in children with chronic arthritis (more than three months' duration). Therapy should be directed at the arthritis per se (synovitis), at the extra-articular manifestations, and at the whole child. Salicylates provide the most satisfactory control of the arthritis per se and of the systemic manifestations in most cases. Iridocyclitis should be managed in consultation with an ophthalmologist. Patients should not be regarded as invalids or restricted needlessly. The prognosis for children with juvenile rheumatoid arthritis is good. In most patients, the disease remits without causing permanent joint damage.

Feline oncornavirus-associated cell membrane antigen. II. Antibody titers in healthy cats from household and laboratory colony environments.

Antibody titers to the feline oncornavirusassociated cell membrane antigen (FOCMA) were determined for 447 healthy cats from laboratory colony and household environments. Only 2.7 percent of 221 cats from colony environments were antibody positive as compared to 50.4 percent of 256 cats from household environments. Incidence of FOCMA antibody and geometric mean antibody titer for pet cats from New York City representing single cat apartment habitats were substantially lower than values for unscreened cats from the Boston, Glasgow, and Detroit suburban environments. Geometric mean antibody titer for young adults in the Boston population was significantly higher than titers for kittens or aged cats. This may be due to greater mobility resulting in increased exposure to other cats. In contrast to the high frequency of FOCMA antibody positivity in pet-cat populations, less than 2 percent of the same groups were positive for virus group-specific antigen in peripheral blood leukocytes and platelets. This was interpreted as an indication that many more cats became infected with feline leukemia virus under natural conditions that the number developing persistent virus infection and/or clinical leukemia.
