RESUMO

We evaluated the efficacy and safety of orally administered bovine tracheal type II collagen (CGII) in the treatment of rheumatoid arthritis (RA). Twenty RA patients received 0.5 mg/day of CGII for 12 weeks. Eighteen of them had improvements in the clinical parameters studied (swollen and tender joint counts, 15-m walking time, duration of morning stiffness, and physician's global assessment of disease activity). Anti-CGII antibodies were positive in 57% and rheumatoid factor (RF) in 71% of the patients with a short history of RA ( < or =2 years), whereas only 23% of those with long histories (>2 years) presented autoantibodies to CGII and 38% had positive RF. After the treatment, four patients showed reduced RF levels and all those with detectable serum tumor necrosis factor alpha (TNF-alpha) experienced its return to normal or levels below those at study entry. Although a placebo effect cannot be discounted, the oral administration of bovine tracheal CGII induced clinical benefits in 90% of the patients, without the side effects usually associated with treatment. This is the first study showing that feeding CGII can induce reductions in RF and TNF-alpha. The data justify further controlled studies to assess the long-term efficacy of this treatment approach.

RESUMO

En este trabajo se presentan los resultados obtenidos en un estudio inmunológico, realizado en un grupo de 13 pacientes con síndrome de hipersensibilidad a la Candida. Los estudios micológicos confirmaron los hallazgos clínicos de candidiasis. En cada uno de los casos se realizó cultivo, tipificación y recuento de colonias, que oscilaron entre 9.800 y 90.000 unidades formadoras de colonias de C. albicans/g de materia fecal peso húmedo. Las pruebas de hipersensibilidad cutánea fueron realizadas con 4 antígenos. Todos los pacientes mostraron positividad en la lectura precoz y negatividad en la tardía a excepción de 4 de ellos. La inmunoglobulina E fue cuantificada por ELISA y se encontraron valores por encima de lo normal en el 84% de los casos. Los valores hallados oscilaron entre 31 y 1000 Ul/ml. El número de LB fue normal en todos los casos mientras que el de LT fue normal en el 46% y disminuídos en el 54% de los pacientes. En ambas determinaciones se usó el método de las rosetas. Las subpoblaciones de LT se determinaron por técnica de inmunofluorescencia indirecta, con anticuerpos monoclonales. Los CD4+ (cooperadores/inductores) se encontraron disminuídos en el 77% de los casos mientras que los CD8+ (citotóxicos/supersores) estuvieron normales en la mayoría de ellos (84%). De acuerdo a estos resultados se puede deducir que existe una estrecha relación entre candidiasis, IgE aumentada e inmunodeficiencia fundamentalmente de la inmunidad mediada por células y en especial de las ...

RESUMO

The serum IgE levels were determined; LB and LT groups and T4 (CD4+) and T8 (CD8+) subgroups were quantified, in 20 patients with immunoallergic respiratory disease (rhinosinusitis and/or bronchial asthma). The IgE levels were raised in 90% of the patients (mean value 412 IU/ml; range 56-1000 IU/ml). The LB count was normal or reduced. There was a relationship between LT count and IgE: for low levels of IgE, the LT count was normal and below normal when the IgE levels were high. The T8 subgroup count was normal in 50% of the patients. The T4 subgroup count was below normal in 80% of the patients. Perhaps, a more detailed study of T4 subgroup components, would explain the immunologic finding in these patients. We can conclude that the immune system must be thoroughly studied before instituting a specific immunotherapy.
