A routine assay for the direct analysis of HLA-DR-related shared epitope and B27 alleles in chronic inflammatory arthritis.

Knowledge of the genetic background of patients with inflammatory arthritis may be useful for disease management. The main markers are the HLA-DR-associated Shared Epitope (SE) for Rheumatoid Arthritis (RA) and HLA-B27 for ankylosing spondylitis. We have developed a simple molecular biology-based test to provide this essential information. HLA targets are amplified by polymerase chain reaction (PCR), then simultaneously analyzed using 16 individual hybridization reactions in two 8-well ELISA strips with colorimetric detection. Concordance was evaluated using a cohort of RA patients with known genotype. Using this new assay, 100% concordance was observed with conventional genotyping in RA patients both for HLA-DR SE and B27 genotypes. Seventy-three percent of the patients with destructive RA had at least one susceptible allele within SE, compared to 38% of those patients with non-destructive disease. This new assay, which requires minute amount of blood, could be used to determine the genetic background of inflammatory arthritis, particularly in non-specialized settings and for large-scale clinical trials.

[Evaluating radiotherapy patients' need for information: a study using a patient information booklet] .

The French Radiotherapy-Oncology Society (SFRO) and the National Trade of Radiotherapists-Oncologists (SNRO) elaborated and published a patient information booklet on radiotherapy, in 1999. This present study appraises the pertinence of the form and substance of this booklet one year after its release. Eight radiotherapy centers participated in this research which evaluated 162 patients at treatment initiation. The conclusions of this study demonstrated the importance of clearly informing patients of their disease, treatment, and the secondary effects of treatment. It is essential to emphasize that 97% of the patients declared that an information booklet is a real necessity, and that the one provided by the SFRO responds to the majority of their concerns. Obtaining technical and practical knowledge resulted in a reassurance about their treatment. The most revealing result is that 87% requested direct communication about their illness, and that cancer be named by this word and not other, evasive terms. Seventy-two percent of the patients requested more information about their cancer, different treatment options, and quality of life issues in an attempt to psychologically prepare themselves to face an illness for which they have little control. Patients refuse to be passive, and claim the right to become 'partners' of the medical teams, concerning their treatment and recovery.
