Safety and Immunogenicity of a Human Papillomavirus Peptide Vaccine (CIGB-228) in Women with High-Grade Cervical Intraepithelial Neoplasia: First-in-Human, Proof-of-Concept Trial.

Objective. CIGB-228 is a novel therapeutic vaccine consisting of HLA-restricted HPV16 E7 epitope adjuvated with VSSP. This trial was designed to evaluate the toxicity, safety, immunogenicity, HPV clearance, and lesion regression.

Relationship of type 1 diabetes to ancestral proportions and HLA DR/DQ alleles in a sample of the admixed Cuban population.

Background: Incidence of type 1 diabetes varies widely around the world, probably due to ethnic differences across populations among other factors.

Aims: To determine whether there is an association between disease and ancestry proportions; and to control disease-HLA associations for possible confounding by admixture or population stratification.

Subjects And Methods: 100 cases and 129 controls participated in the study.

HLA class I polymorphism in the Cuban population.

The extreme polymorphism found at some of the human leukocyte antigen (HLA) system loci makes it an invaluable tool for population genetic analyses. In the present study the genetic polymorphism of the Cuban population was estimated at HLA-A, -B, and -Cw loci by DNA typing. HLA class I allele and haplotype diversity were determined in 390 unrelated Cuban individuals (188 whites and 202 mulattos) from all over the country.

ACE I/D polymorphism study in a Cuban hypertensive population.

Background: The angiotensin converting enzyme (ACE) is a key protein of the renin angiotensin system, whose main function is the conversion of angiotensin I to II. ACE is involved in the physiological control of blood pressure and it is a candidate gene for essential hypertension in humans. We tested the relevance of the ACE insertion/deletion (I/D) polymorphism in our population.

HLA DQA1*0501 and DQB1*02 in Cuban celiac patients.

Celiac disease (CD) susceptibility has been strongly associated with HLA-DQ2 and HLA-DQ8. The main objective of this study was to assess the distribution of HLA DQA1*0501 and DQB1*02 alleles (DQ2) for the first time in a group of Cuban celiac patients. We evaluated 22 patients, 54 first-degree relatives, and 60 controls for detection of antitissue transglutaminase (tTG)-specific antibodies in serum.
