title: [Laboratory diagnostic and prognostic factors: Multiple myeloma in Morocco].
abstract: ObjectivesThe purpose of this retrospective study was to clarify the factors for a laboratory diagnosis of multiple myeloma (Kahler's disease) and assess their prognostic value.MethodsThe study of all 10 patients with multiple myeloma seen during 2009 in the department of internal medicine and the haematology laboratory of HASSAN II University Hospital Centre in Fez. Work-ups for all patients included hemograms, sedimentation speed, electrophoresis of serum and urinary proteins, myelograms, creatinemia, calcemia, ß2-microglobulin, LDH and CRP.ResultsIn this series, the average age of the patients was 59 years and the sex ratio 1.3 (men). The laboratory tests showed anemia below 12 g/dl in 80% of the cases, with IgG accounting for 50% of the cases. The median concentration of the monoclonal component was 28 g/l. The prognostic assessments showed an increase in ß2-microglobulins and creatinemia in one case. CRP was elevated in all patients.ConclusionThe results from this study are consistent with those from other series. Protein electrophoresis and myelography results are major diagnostic elements, because they make it possible to rule out a monoclonal gammopathy of undetermined significance, for which treatment differs completely from that for multiple myeloma. ß2-microglobulin and CRP are independent prognostic factors providing important information about survival.
