Behçet's disease is an inflammatory disease characterized by recurrent oral and genital ulcers and significant organ involvement. Localizing the genetic association between HLA-B*51 and Behçet's disease and exploring additional susceptibility loci in the human leukocyte antigen (HLA) region are complicated by the strong linkage disequilibrium in this(More)
Behçet’s disease (BD) is a multisystemic inflammatory disorder of unknown etiology that is sometimes associated with thrombosis. However, the mechanism of hypercoagulability is not known. In this study, we investigated whether hyperhomocysteinemia, being a well-known risk factor for thrombosis, is also a contributing risk factor to venous and arterial(More)
The aims of this study were to determine the antimicrobial susceptibility patterns of urinary isolates from community acquired acute uncomplicated urinary tract infections (uUTI) and to evaluate which antibiotics were empirically prescribed in the outpatient management of uUTI. Among the patients which were admitted to outpatient clinics of Ankara(More)
Adult-onset Still’s disease (AOSD) has often been regarded as the adult spectrum of systemic juvenile idiopathic arthritis (sJIA). The present study aims to compare the clinical and laboratory features, the disease course and the response to treatment in patients having AOSD with those having sJIA. Retrospective review of all available data that were filled(More)
Although it has been reported that the MHC class I molecule, HLA-B51, is a risk factor for Behçet’s disease (BD), contribution of the tumor necrosis factor (TNF) genes, which are located in the vicinity of the HLA-B locus, to the genetic susceptibility for BD has yet to be elucidated. The purpose of this study was to analyze the effect of TNF-α promoter(More)
Acute rheumatic fever (ARF) is a systemic inflammatory disease occurring as a consequence of an exaggerated immune response to group A, beta haemolytic streptococcal pharyngitis. The molecular mimicry between human target organs/tissues and specific components of the infectious organism leads to the development of autoimmune reactions and cardiac tissue(More)
Rheumatic heart disease (RHD) or acute rheumatic fever (ARF) develops as a consequence of an exaggerated immune response to Group A beta haemolytic streptococci causing pharyngitis. The molecular mimicry appears between human cardiac myosin and M protein of group A streptococcal membranes. The polymorphism of the protein tyrosine phosphatase nonreceptor 22(More)
Acute rheumatic fever (ARF) is a systemic inflammatory disease that develops as a consequence of an exaggerated immune response to group A beta-haemolytic streptococci, which causes pharyngitis. Major manifestations of ARF include carditis, arthritis and chorea. Several investigators have attempted to establish a relation between ARF and human leucocyte(More)
INTRODUCTION HLA-B*51 and HLA-B*52 are two close human leukocyte antigen (HLA) allele groups with minor amino acid differences. However, they are associated with two different vasculitides (HLA-B*51 in Behçet's disease and HLA-B*52 in Takayasu's arteritis (TAK)) and with major clinical and immunological differences. In this study, we aimed to screen a large(More)
Acute rheumatic fever (ARF) is a non-suppurative inflammatory disease after group A, β haemolytic streptococcal pharyngitis. Certain individuals can develop ARF. This finding implies variability in host predisposition to ARF. A variety of studies have linked specific genetic markers with ARF or rheumatic heart disease (RHD) as a sequelea of ARF. For this(More)
