HLA-B*3531, a hybrid of B35 and B61, implications for diagnostic approaches to alleles with complex ancestral compositions.

The serological characterization of allelic variants that have been generated by large-scale interallelic recombination events indicates which residues may be involved in the formation of epitopes crucial for serological recognition. The allelic product of HLA-B*3531 is composed of B35 in its alpha1 domain and of B61(40) in its alpha2 domain. Both specificities are only weakly detectable with available sera. Allelic products with 'mixed' serology also represent a challenge to DNA-based HLA typing methods, as only the sequence motif of one ancestral allele may be recognized. In this case the hidden specificity would not be considered in the matching process and might not be recognized as an antigen 'unacceptable' to the recipient.

Using a primary nurse manager to implement DCCT recommendations in a large pediatric program.

PURPOSE: This study was conducted to determine whether recommendations from the Diabetes Control and Complications Trial (DCCT) could be implemented in a large pediatric population using a diabetes clinical nurse specialist program coordinator dedicated to intensive management. METHODS: Patients' charts were reviewed to examine HbA1c levels from before the results of the DCCT were published and again 1 year after the recommendations were implemented. Patients who met the following criteria (N = 124) were enrolled: type 1 diabetes, less than 18 years old, followed at Yale for 1 year prior to the results of the DCCT and 1 year after, and HbA1c level recorded in the medical chart. RESULTS: HbA1c levels were significantly lower 1 year after implementing the DCCT protocol; 3 years later these same patients improved even further as evidenced by another decrease in HbA1c levels. The patients were taking more insulin (more Ultralente and regular insulin and less NPH) and had an increased number of injections at both the 1-year and 3-year follow-up points. CONCLUSIONS: The DCCT protocol can be implemented in a large population of pediatric patients with the help of a nurse who is dedicated and available to the patients for ongoing adjustments and provides creative ways to overcome the barriers to achieving normoglycemia.
