Cytokine Gene Polymorphism in BCG Lymphadenopathy

cytokine gene polymorphism in bcg lymphadenopathy

background: tumor necrosis factor-beta or lymphotoxin-alpha (lt- α ), il-4 and il-10 are determining factors in immunity against bcg.  allelic polymorphisms in the regulatory regions of their genes affect the rate of cytokine production and therefore, the host’s ability in bcg containment.   objective : to study the prevalence of –590 (c/t) and –592 (c/a) allelic distribution of il-4 and il-10 ...

BCG lymphadenopathy detected in a BCG-vaccinated infant.

Large-scale vaccination with BCG, the live attenuated strain of Mycobacterium bovis, is being adopted around the world, although sporadic complications have occurred after the procedure. Lymphadenopathy is not uncommon especially in babies under one year (0.73% of vaccinated infants), but the swelling subsides within 2 months in most cases, with no medical or surgical treatment. Brazil adopted ...

Cytokine Gene Polymorphism and Infection

Th1 and Th2 Cytokine Gene Polymorphism in Iranian Patients with Chronic Myelogenous Leukemia

Background:It has been hypothesized that genetic factors other than histocompatibility disparity may play a role in predisposition to developing Chronic Myelogenous Leukemia (CML). In this regard, Th1 and Th2 cytokines and their gene polymorphism seems to be important. Overall expression and secretion of cytokines is dependent, at least in part, on genetic polymorphism (nucleotide variations) w...

Cytokine gene polymorphism in recurrent acute otitis media.

BACKGROUND There is increasing evidence that a strong genetic component is involved in the predisposition to recurrent acute otitis media (rAOM). Cytokines play a key role in the pathogenesis of otitis media. Constitutional polymorphisms in cytokine genes may lead to individual variations in cytokine secretion. OBJECTIVE To elucidate the role of cytokine gene polymorphisms in rAOM. SETTING ...

Patterns of cytokine gene expression in peripheral T-cell lymphoma of angioimmunoblastic lymphadenopathy type.

Peripheral T-cell lymphoma of angioimmunoblastic lymph-adenopathy type (AILD-TCL) is histologically characterized by a mixed infiltrate of atypical T cells, B cells including B immunoblasts, and plasma cells, as well as eosinophilic granulocytes accompanied by proliferated high endothelial venules, while, clinically, fever and weight loss are often observed. These morphologic and clinical pecul...
