Thirty seven Chinese adults and 23 children in Hong Kong with myasthenia gravis were tested for HLA-A and -B antigens and acetylcholine receptor (AChR) antibody. HLA BW46 had a significantly increased prevalence in patients with juvenile onset ocular myasthenia gravis. Only one third of the juvenile ocular patients had AChR antibodies and the titres were generally low. In the adult patients tak...

Human leukocyte antigen (HLA) genes have been associated with susceptibility and protection against a number of cancers. Here we used an immunogenetic epidemiological approach to evaluate the overall influence 127 HLA Class I II alleles on 30 types cancer. We found preponderance protective (negatively correlated cancer prevalences), especially for I. Of cancers investigated, 13 were mostly effe...

Objective To better characterize the genetic association between human leukocyte antigen (HLA) and anti-IgLON5 disease to explore auto-antigen binding associated HLA molecules their functional involvement in pathophysiology. Background Anti-IgLON5 is a rare, but likely underdiagnosed type of autoantibody encephalitis with heterogeneous clinical phenotype, including sleep, movement brainstem dys...

Employing five radioimmunoassays for immune complexes, the sera of 45 acute and 27 postacute follow-up sera from patients with acute rheumatic fever were examined. All patients experienced actue polyarthritis. Complexes were detected in 89% of acute-phase sera by one assay, 51% by two, 29% by three, and 7% by four. Immune complex values decreased significantly at followup, although some abnorma...

Background: It has been arguedthat unprecedented degree of human leukocyte antigen (HLA) loci polymorphism within a population is requiredto avoid the devastating effects of infectious diseases. The present study was conducted to determine the associations between some of HLA classI genes and the outcome of hepatitis B virus (HBV) infection. Methods: Using sequential sampling method, 64 individ...

  Background and Objective: The outcome of hepatitis B virus (HBV) infection may be influenced by host factors like Human Leukocyte Antigen (HLA). We have investigated HLA-A and DRB1 alleles in patients with persistent hepatitis B infection compared to subjects who had spontaneously recovered from HBV infection. To complete the findings of this study we performed another survey in certain HLA ...

Gluten sensitive enteropathy also known as Celiac disease, an autoimmune disorder which occurs in the presence of HLA DQ2 & DQ8 gene genetically susceptible individuals. Homoeopathy can direct treatment constitutionally and therapeutically. Gliadin a derivative gluten is modified by TTG seen antigen to Antigen presenting cells. The lead failure thrive.

Using a standard microcytotoxicity (NIH) technique of tissue typing, the HLA-B27 antigen was identified in 30 out of 34 patients (HH.2%) with classical ankylosing spondylitis (AS), compared to 6 out of 70 controls (H.6%) (P < 0.005). We also found this antigen in 8 out of 76 (10.5%) patients with non-AS arthritis.

Human Leukocyte Antigens (HLA) of fetus are responsible for induction of HLA antibodies in mother. Exposure to the mismatched paternal HLA antigens in the fetus gives rise to a polyclonal antibody response against paternal HLA antigens. HLA antibodies are present in the maternal circulation of the placenta and are absorbed onto the placenta [1]. The major source of HLA antisera is from sera of ...

diseases and is divided into two vulgaris and foliaceus pemphigus and mainly appears during fifties and sixties.1,2 Its etiology is not exactly known and genetic talent may play a role in its development.3,4 The disease is globally widespread and is more common in some races.5,6 A study was conducted to evaluate the HLA-class I in patients suffering from pemphigus. Patients with skin biopsy of ...
