504 healthy infants, born to HBsAg negative mothers from May 1st to December 31st 1991, were randomly allocated to an accelerated (group A) or traditional (group B) immunization schedule. The group A infants were immunized at 4 days, 1 month and 3 months of life with 10 micrograms of recombinant HBV vaccine (Engerix B, SKF) while the group B infants were immunized at 4 days, 1 month and 6 months of life with the same dose of vaccine. One month after the first dose of vaccine, 9.2% of the infants in both groups had an HBsAb serum level > 10 mIU/ml. One month after the booster dose, at 4 months of life for group A and at 7 months for group B, 97.40% and 98.53% of the infants presented a serum level > 10 mIU/ml respectively. None in group A and only 2 patients in group B could be considered non-responders (serum concentration below 2 mIU/ml) and 4 infants in group A and 4 in group B were considered hypo-responders (serum level between 2.1 and 9.9 mIU/ml). Immunogenetic study performed on the 2 non-responders and 6 of the hypo-responders, revealed the presence in all but two of the HLA haplotypes, classically involved in the lack of hyporesponsiveness to foreign peptides, namely: HLA-DR7; DQ2, DR4; DQ3, DR15; DQ6 and DR3; DQ2. Surprisingly, 2 hypo-responders carried the HLA haplotypes (DR11, DQ7 and DR13, DQ6), usually associated with hyperresponsiveness. Both vaccinal cycles provided evidence that infants respond well to vaccination, started at birth, against hepatitis B virus with a high degree of protection.(ABSTRACT TRUNCATED AT 250 WORDS)

A patient with cervical non-Hodgkin lymphoma was treated with chemotherapy. Fourteen months after the diagnosis of the lymphoma, an endometrial adenocarcinoma was detected as a secondary malignant tumor. The patient was treated with surgery followed by radiotherapy. Approximately 7 years after the diagnosis of endometrial cancer, vaginal invasive squamous cell carcinoma was diagnosed as the third primary malignancy, and a second-line palliative radiotherapy was applied. Seven months after the last radiotherapy, postradiational sarcoma in the vagina was diagnosed. Congenital and acquired immune system disorders, viral oncogenes, and various human leukocyte antigen (HLA) types were investigated. Total blood count and lymphocyte subset analysis were performed, and CD4+ lymphopenia was detected. Serologic tests were carried out for human immunodeficiency virus, hepatitis B virus, human papillomavirus, Epstein-Barr virus, and herpes simplex virus infection. Epstein-Barr virus viral capsid antigen IgG was found positive. Low-risk human papillomavirus panel was detected by Hybrid Capture method in the cervical smear. The HLA investigation revealed HLA-A2, HLA-A3, HLA-B57, HLA-B35, HLA-B4, HLA-B6, HLA-DR3, HLA-DR1, HLA-DR51, HLA-DR52, HLA-DQ6(1), and HLA-DQ7(3). The patient died because of the disease.

Antibody-mediated rejection after liver transplant, especially when the donor is not a direct relative; it is associated with additional inconvenience for patients. We encountered a case in which antibody-mediated rejection because of de novo donor specific antibodies against donor human leukocyte antigen developed 6 months after ABO-compatible living-donor liver transplant and was treated with retransplant. A 38-year-old man with hepatitis B virus-related hepatocellular carcinoma underwent living-donor liver transplant with a graft from his wife. Six months later, he experienced fatigue and jaundice. Liver biopsy revealed C4d deposits, and histologic examination showed an antibody-mediated rejection pattern. We re-evaluated recipient-donor human leukocyte antigen matching and tested the patient's blood for antihuman leukocyte antigen donor-specific antibodies against donor human leukocyte antigen. De novo auto-antibodies against human leukocyte antigen-DQ6 were identified by Luminex single antigen beads.Because exhausting all treatment options, a rescue second living-donor liver transplant was planned with the patient's stepdaughter as the donor. Pretransplant human leukocyte antigen matching was performed, and the patient was discharged without event. Two months later, hyperbilirubinemia was noted, and a residual common bile duct from the first donor with chronic fibrosis and stricture was strongly suspected. Redo hepaticojejunostomy was successfully performed, with no problems during 1-years' follow-up. Thus, liver retransplant could be a rescue treatment for antibody-mediated rejection complicated with hepatic failure.
