title: [Value of the protein profile in unexplained inflammatory syndromes].
abstract: The diagnosis of unexplained inflammatory syndromes requires many investigations which are commonly expensive, often invasive and must be repeated several times. A means for physicians to improve the diagnosis procedure would be to have new tests available to select the best diagnosis procedures. In order to test the value of the protein profile (PP) in the case of unexplained inflammatory syndromes, we prospectively studied 95 among 650 patients admitted in our unit for an inflammatory syndrome defined by a C Reactive Protein level > 2 mg/dL and a sedimentation rate > 30 mm, which remained unexplained after a 5 day hospitalization (49 men, 46 women; mean age: 62.9 +/- 12.3 years). PP has been considered as a useful test for the diagnosis in 21 cases (22%) having been definitively established by pathologic examination (42%), radiologic procedures (24%), endoscopy (19%), immunological tests (19%), and serological test (9.5%). The definitive diagnosis was a systemic disease in 12 cases, infection (four cases), malignancy (three cases), amyloidosis (one case) and occult intestinal bleeding (one case).
  
  
  CONCLUSIONS
  Our data indicate that PP is a useful test for the diagnosis of unexplained inflammatory syndromes; its main utility is the disclosure of some specific biochemical syndromes available for better selecting the definitive diagnosis procedures.
