Therapeutic effectiveness of paracetamol in rheumatoid arthritis.

A single-blind, non-crossover study of the effectiveness of paracetamol, compared with aspirin and indomethacin has been carried out in 143 patients suffering from rheumatoid arthritis. Subjective indices have been employed, and the validity of the present method is discussed. The results of the trial have also been compared with those of a previous study (of prednisone, aspirin and placebo). Paracetamol was not significantly different from placebo, either in terms of pain relief or patient satisfaction rating. Prednisone and indomethacin were significantly better than paracetamol in respect to both parameters, but aspirin was not. On the basis of these results, the frequent prescription of paracetamol as the main therapeutic agent in the treatment of rheumatoid arthritis is not justified.

The origins and relative distribution of polysaccharidases in rheumatoid and osteoarthritic fluids.

Three lysosomal polysaccharidases were measured in synovial fluid (SF) and serum from rheumatoid (RA) patients, SF from osteoarthritic (OA) patients, and serum from healthy volunteers. (1) There was no correlation between the enzyme levels and white cell counts in the SF. (2) beta-glucuronidase and beta-N-acetylglucosaminidase were markedly elevated in the SF of RA as compared to OA. (3) beta-glucuronidase and beta-N-acetylglucosaminidase levels in the SF of RA correlated well with each other but not with hyaluronidase. (4) beta-glucuronidase and beta-N-acetylglucosaminidase levels were higher in the SF of RA than in the corresponding serum, while the converse was true for hyaluronidase. (5) Hyaluronidase levels were significantly higher in RA serum than in normal serum. These results suggest that the synovial membrane may be the source of beta-glucuronidase and beta-N-acetylglucosaminidase, while hyaluronidase is derived from a source remote from the joint via the serum. This source of hyaluronidase may be the liver. (J Rheumatol 2: 393-400, 1975).

Effective immunity to dental caries: protection of gnotobiotic rats by local immunization with Streptococcus mutans.

Gnotobiotic rats injected in the submandibular region with killed, whole Streptococcus mutans cells developed salivary antibodies directed to this microorganism. Increased levels of salivary IgA and inhibition and augmentation of agglutinin titers with anti-rat alpha-antiglobulin suggested that these antibodies were of the immunoglobulin A class. Furthermore, the rats monoinfected and immunized with homologous organisms always had lower mean caries scores than monoinfected, non-immunized rats. This reduction was evident in carious lesions on the buccal surfaces of molars and in those in sulcal areas. These results suggest that local immunization with whole S. mutans cells stimulates a specific salivary IgA response protective against caries resulting from S. mutans infection.
