HLA class I haplotypes and progression of primary open-angle glaucoma.

Purpose: To verify if patients with primary open-angle glaucoma with HLA class I haplotypes (A9-B12, A2-B40, A1-B8) associated with this disease may have a greater rate of progression than patients who do not present these haplotypes.

Methods: Anatomical and functional glaucoma evaluation (cup-to-disc ratio and visual field) of 25 patients (six of them with one of the haplotypes associated with glaucoma) followed at the Glaucoma Outpatient Clinic of the University Hospital, Ribeirão Preto School of Medicine, São Paulo University (HCFMRP-USP) for ten years after typing of their HLA antigens in order to compare with their previous condition.

Results: A greater increase of the cup-to-disc ratio was observed in patients with HLA haplotypes associated with primary open-angle glaucoma predisposition.

Immunohistochemical expression of HLA-DR in the conjunctiva of patients under topical prostaglandin analogs treatment.

Purpose: Subclinical inflammation may be observed in patients using topical antiglaucomatous drugs. The objective of this study was to investigate inflammation in conjunctiva of glaucoma patients using prostaglandin analogs, by the detection of an immunogenetic marker (HLA-DR) and compare the effect of 3 different drugs: latanoprost, bimatoprost, and travoprost in the induction of this inflammation.

Subjects And Methods: Thirty-three patients with primary open-angle glaucoma were evaluated without and with prostaglandin analogs topical therapy.

HLA profile in patients with AIDS and tuberculosis.

Studies carried out in various populations have reported an association between some HLA specificities and susceptibility to tuberculosis. We investigated the class I and class II HLA profile in Brazilian patients of various ethnic backgrounds who had AIDS and tuberculosis. Twenty-two adult patients with AIDS and tuberculosis (Group I), 103 patients with AIDS without tuberculosis (Group II) and 423 healthy individuals not infected with HIV (Group III) were evaluated.
