Gluten-dependent enteropathy and atypical human leukocyte antigen alleles.

The risk for developing celiac disease is associated with the major histocompatibility complex class II human leukocyte antigen DQ2 and DQ8. We retrospectively reviewed the medical records of 127 consecutive cases of adult-onset celiac disease evaluated at a single United States center to determine the distribution of the associated human leukocyte antigen DQA1 and DQB1 alleles. The median patient age of diagnosis was 41 (range, 16-81) years.

HLA class I allelic diversity and progression of fibrosis in patients with chronic hepatitis C.

Patients infected with HIV-1 who are heterozygous at HLA class I loci present greater variety of antigenic peptides to CD8+ cytotoxic T lymphocytes, slowing progression to AIDS. A similar broad immune response in chronic hepatitis C (CHC) infection could result in greater hepatic injury. Although specific HLA class II alleles may influence outcome in CHC patients, the role of HLA class I heterogeneity is generally less clearly defined.

Campath-1H induction plus rapamycin monotherapy for renal transplantation: results of a pilot study.

Campath-1H, an anti-CD52 monoclonal antibody, was used as induction therapy (40 mg i.v. total dose) in 29 primary human renal transplants, and the patients were maintained on rapamycin monotherapy (levels 8-15 ng/mL) post-transplant.
