    ABSTRACT: We report the case of a 70 years old patient hospitalized for renal insufficiency and deterioration of the general state. The electrophoresis of serum proteins on freezing of agarose reveals the presence of a discrete peak of monoclonal pace on the level of the gammaglobulines identified by serum immunofixation like IgM of the kappa type. The research of the cryoglobulinemia carried out in a laboratory of city was made positive and typified like a monoclonal cryoglobulinemia IgM kappa, thus directing the diagnosis towards a disease of Waldenström. However, the result of the biopsy medullary made exclude any lymphoprolifératif syndrome. The positivity of the serology of hepatitis B justified a second request for study of the cryoglobulinemia, carried out within our laboratory. The cryoglobuline was typified like mixed (IgM kappa monoclonal and IgG polyclonales). This result associated with the immunological assessment and the renal biopsy made retain for our patient the diagnosis of a kidney vasculitis connected to an infection chronicle by the virus of hepatitis B. This observation points out the interest of the preanalytic, analytic and post analytic phases in the study of the cryoglobulinemias. A good technical control is today the only guarantee of the quality of the result of this examination which has large importance in internal medicine in the etiologic assistance with the diagnosis of certain clinical demonstrations.

    ABSTRACT: Allergic diseases are ranked fourth considering the world health organization classification of diseases. The consequences linked to these ailments are huge for public health economics and the diagnosis is awkward due to clinical polymorphism and multifactorial aetiologies. The allergologic diagnosis is the result of weighing in clinical and biological findings. The biological assessment is made of qualitative specific and multiple-allergen serum IgE test, which once positive drives to skin test and each allergen-specific IgE level determination to conclude. Our study aims at displaying biological analysis results of incoming patients with clinical allergy conditions. We carried out a nine months retrospective study, from June 2007 to March 2008, with 200 outwards patients involved. Blood samples were collected using dry tubes and as recommended we first did screening tests for respiratory (Pharmacia Phadiatop) and food (fx 5) allergens, then for positive samples we proceeded to serum specific IgE assay (UniCap, Phadia). We also realized the total IgE assay on 46 patients using Roche Elecsys 2010 technology. 49% of patients enrolled in the study were positive to aerollergens, d1 Dermatophagoides pteronyssinus being the most incriminated (96.4%), and 2.5% to food allergens. On 13% of patients, we noticed a double sensitization to d1 and g6 (pollen of grasses). Concerning the total IgE dosage, we found 50% of patients tested with normal values, 28% of whom having a positive allergologic screening test. Further studies matching clinical data, skin tests to serum IgE assay are necessary to draw the profile of respiratory and dermatological allergies for our patients.
