[Information and consent forms for hematopoietic stem cell transplantation donors and recipients: Guidelines from the Franchophone society of bone marrow transplantation and cellular therapy (SFGM-TC)].

Within the context of the SFGM-TC's 6th workshop series on the harmonization of clinical practices, our workshop proposes a standardization of the informed consent process for hematopoietic stem cell donors and recipients leading up to an autologous or allogenic transplantation. All informed consent was for bone marrow or peripheral stem cell donors, and mononuclear/lymphocyte donors according to usual procedures. The informed consent for autologous and allogenic related or unrelated adults and pediatric transplantation patients have been included.

Development of miniaturized immunoassay: influence of surface chemistry and comparison with enzyme-linked immunosorbent assay and Western blot.

Protein microarray technology provides a useful approach for the simultaneous serodetection of various antibodies in low sample volumes. To implement functional protein microarrays, appropriate surface chemistry must be designed so that both the protein structure and the biological activity can be retained. In the current study, two surface chemistries for protein microarrays and immunofluorescent assays were developed.

A new target for autoantibodies in patients with rheumatoid arthritis.

Early treatment of rheumatoid arthritis (RA) with disease-modifying antirheumatic drugs can achieve a better disease outcome and reduce the severity of joint damage. The presence of autoantibodies in patient sera can precede onset of the disease and thus be predictive of the development of RA. To date, known autoantibodies in RA are positive in only 50-60% of RA patients at onset of disease and even less before the onset of any RA symptom.

Carbonic anhydrase III: a new target for autoantibodies in autoimmune diseases.

The objective of this study was to identify new autoantibodies that could be useful for the diagnosis of rheumatoid arthritis (RA) using immunoblotting on synovial membrane proteins which represent the best source of candidate RA autoantigens. A new target protein with a molecular weight of 26 kDa was found to be recognized by autoantibodies in RA sera and was identified using MALDI-TOF mass spectrometry and second-dimension electrophoresis as carbonic anhydrase III (CAIII). Three similar protein spots at 26 kDa were recognized by both human sera and monoclonal antibody (mAb) directed against CAIII on immunoblotting using the human recombinant CAIII.

Calcium-sensing receptor autoantibodies are relevant markers of acquired hypoparathyroidism.

We investigated the presence of autoantibodies (aAbs) directed against the parathyroid gland in 17 patients with spontaneous isolated acquired hypoparathyroidism. Fourteen patients with acquired hypoparathyroidism (AH) associated with type I or II autoimmune polyendocrinopathy syndrome were also tested in comparison with a control group of 68 subjects without AH, including patients with other autoimmune diseases and healthy blood donors. aAbs against parathyroid tissue were screened using an indirect immunofluorescence technique on primate parathyroid tissue and human parathyroid adenoma.
