OBJECTIVES In Morocco, the patients affected by ankylosing spondylitis (AS) presents a high frequency of coxitis. Our study reports, for the first time, the polymorphism of Human Leukocyte Antigen (HLA) class I and class II molecules in the Moroccan patients. METHODS Forty-six patients diagnosed with an AS and coxitis were compared to a group of 183(More)
Rejection occurs after the introduction of a genetically different graft, in a recipient. Nowadays, it is still a major obstacle in renal transplantation and reflects a normal protective immune response of a recipient against a foreign antigen. Involving many mechanisms of the innate and adaptive immunity, this reaction results in renal parenchymal lesions(More)
The toll-like receptors are innate immunity receptors which recognise particular exogenous structures in the microorganisms pathogen associated molecular pattern (PAMP) and endogenous structures damage-associated molecular patterns (DAMP). Eleven TLR have been identified among human beings. These are danger receptors located in the cells of the immune(More)
In recent years the T CD4+ lymphocyte family has grown. In the initial two components TH1 and TH2 lymphocytes were added the TH17 lymphocyte and T cell regulator (Treg). Under the influence of transforming growth factor β, interleukin 6 (IL6), IL21 and IL23, the naive lymphocyte T CD4+ differentiates in TH17. Currently, the TH17 is recognized as the leading(More)
OBJECTIVES We have study the various associations between Behçet disease and alleles HLA class I and II in Moroccan population. The distribution of HLA alleles involved in the disease is assessed according to clinical signs and sex. PATIENTS AND METHODS Patients suffering from Behçet's disease have been compared to healthy controls matched by age and(More)
OBJECTIVES The Luminex technology is the most sensitive diagnostic method for HLA antibody detection and identification. However, the interpretation of immunoassays is commonly affected by the artifact, and non-specific background. Sera from some patients show high negative control bead (NC) value, which makes assessing and interpretation of HLA antibodies(More)
The management by objectives method has become highly used in health management. In this context, the blood transfusion and haemovigilance service has been chosen for a pilot study by the Head Department of the Ibn Sina Hospital in Rabat. This study was conducted from 2009 to 2011, in four steps. The first one consisted in preparing human resources(More)
Lupus nephritis (LN) is a disease with a poor prognosis. The association between LN and the Human leukocyte antigen (HLA) genes has never been studied on a Moroccan population. The aim of this work was to evaluate the distribution of the HLA class II alleles in patients with LN and to determine susceptible and protective HLA alleles/haplotypes in LN. The(More)
INTRODUCTION The Luminex® technology has become an integral component of clinical decision-making and diagnosis of transplanted organ rejection. Despite the superior sensibility of this technology, it is not completely problem free. We have observed in these bead-based assays that sera of some patients give a high negative control bead (NC) value which(More)
PURPOSE OF STUDY The blood transfusion and haemovigilance service of the Ibn-Sina hospital in Rabat (Morocco) was created 1997. This unit manages the pretransfusional tests, distribution of blood products, traceability and haemovigilance. The objective of this study was to analyze, over a period of 12years, the traceability of blood products delivered in(More)
