Characterisation of the Novel HLA-B*51:409N Allele by Next-Generation Sequencing.

HLA-B*51:409N differs from the HLA-B*51:01:01:01 by one nucleotide at position 923 in exon 3.

False Positive B-Cells Crossmatch after Prior Rituximab Exposure of the Kidney Donor.

Crossmatching is essential prior to kidney transplantation to confirm compatibility between the donor and the recipient, particularly to prevent acute antibody-mediated rejection. An unexpected positive crossmatch may be obtained in recipients with an autoimmune disease or preexisting antibodies not detected by single-antigen bead array due to complement interference or who have been previously treated by desensitization protocols such as rituximab, antithymocyte globulin, or intravenous immunoglobulins. We report donor and recipient investigations that revealed unexpected positive B-cells crossmatch, probably due to donor cells, as the donor had received rituximab therapy shortly before organ harvesting, in a context of severe idiopathic thrombocytopenic purpura.

Evaluation of efficacy and safety of itraconazole oral solution for the treatment of oropharyngeal candidiasis in aids patients.

This study was a non-comparative multicenter clinical trial to evaluate the efficacy and tolerability of itraconazole oral solution 200 mg/day (100 mg twice a day in the fasting state) for the treatment of oropharyngeal candidiasis in AIDS patients. We included 50 patients who were treated and followed for up to 3 weeks after ending therapy in the analysis. Mycological cures at the end of therapy occurred in 20/50 patients (40%), but colonization by Candida sp.

Cellular and plasma viral load in patients infected with HIV-2.

Objective: To determine circulating viral load in HIV-2-infected individuals.

Methods: Viral load was determined in 40 HIV-2-infected adults using standardized quantitative cell and qualitative plasma viraemia assays. We also tested for proviral HIV-2 DNA using single and nested polymerase chain reaction (PCR) in fresh lymphocytes from 27 subjects.
