[Diagnosis of adult-onset Still's disease: contribution of biology].

We report one case of adult-onset Still's disease. The diagnosis of this disease currently requires application of Yamaguchi's criteria and then exclusion of infectious, haematological, autoimmune and neoplasic disorders. The place of biology is enhanced with the use of new markers like ferritin and glycosylated ferritin.

[Multicenter evaluation of thr Abbott glycosylated hemoglobin assay on IMx].

The Abbott IMx glycated hemoglobin assay was evaluated in a multicentre study. This method utilizes boronate affinity chromatography, and ion-capture technology. This assay determines both total glycohemoglobin (% GHb) and percentage of hemoglobin Alc (% HbAlc).

Comparison of six serum ferritin immunoassays and isoferritin spectrotypes in malignancies.

Serum ferritin was measured by six enzyme immunoassays in specimens from patients with digestive cancers (n = 30) and hematologic malignancies (n = 33). Most mean comparisons show significant differences in both groups of patients. In digestive cancers correlations between any two methods are very satisfactory (r > 0.

Serum ferritin and isoferritins are tools for diagnosis of active adult Still's disease.

Objective: Still's disease is an acute systemic inflammatory disorder. There are no pathognomonic symptoms or specific laboratory abnormalities. Serum ferritin concentration in rheumatoid arthritis together with some plasma glycoproteins such as alpha 2-glycoprotein and C-reactive protein are part of the response to inflammation.
