Biological Basis of the HLA-B8,DR3-Associated Progression of Acquired Immune Deficiency Syndrome

1998

The factors influencing the evolution of human immunodeficiency virus (HIV) infection are not fully known, but the host genotype undoubtedly plays a role in determining the outcome of the disease by affecting the immune response to HIV. The role of the host human leukocyte antigen (HLA) genotype in the regulation of susceptibility to HIV infection and expression has been studied extensively in different major risk groups. Certain HLA alleles and haplotypes, being associated with aberrant immune responses independently from HIV infection, have been reported to facilitate the rapid progression of disorders related to HIV infection. Particularly, the association of rapid acquired immunodeficie…

Seguint la pista del VIH: els estudis evolutius i la comprensió de la sida.

2013

El VIH o virus de la immunodefi ciencia humana te un gran impacte sanitari, social i economic; les terapies actuals permeten controlar la infeccio pero no s’ha trobat tractament guaridor ni vacuna efectiva. Per a aconseguir aquests objectius, ha de tenir-se en compte la gran variabilitat genetica i la rapida evolucio del VIH, associades, per exemple, a l’aparicio de variants de resistencia a farmacs o de canvis antigenics.

A qualitative model of the HIV vital cycle

1992

Qualitative modelling is a recent artificial intelligence approach to physical system modelling. This approach has been successfully applied in several fields. On the basis of an analysis and qualitative modelling of cell growth, we reckon that a qualitative model of the vital cycle of HIV can be proposed, including the phases in which HIV can be attacked. The actions of antiviral drugs can also be qualitatively modelled, provided their action mechanism is known, even only in a broad sense.

Augmented Passive Transfer of Contact Sensitivity in Severe Combined Immunodeficiency Mice and Its Dependence of Vβ8<sup>+</sup> Cells in…

1993

The passive transfer of contact sensitivity using picryl chloride immune cells from H-2 syngenic BALB/c donors was analyzed in severe combined immunodeficiency (SCID) mice which lack functional T and B lymphocytes. H-2-restricted and antigen-specific contact sensitivity was transferred to SCID mice, and comparison between the level of contact sensitivity and the number of transferred cells showed a significantly more efficient transfer to SCID than to BALB/c mice. The cells passively transferring contact sensitivity were shown to carry the Vβ8 phenotype. Moreover, chromium-labeled cells from BALB/c PC1-primed donors localize normally in peripheral lymphoid organs, and an increased percentag…

Pefloxacin in the Antibacterial Treatment of Immunodepressed Patients

1990

Pefloxacin 800 to 1200 mg daily was given for 3 to 20 days, orally or intravenously, to 84 immunocompromised patients. Five patients dropped out because of side effects and 2 for other causes. Treatment efficacy was evaluated in 77 patients, 43 men and 34 women, aged 18 to 80 years. Immunodepression resulted from malignancy in 46 patients, LAS/ARC or AIDS in 28, and from unknown causes in 3. Fifty-eight patients had documented infections (respiratory-tract infections 29, urinary-tract infections 13, septicemia 10, other 6) and 19 had a fever of unknown origin (FUO). Cure or significant improvement of symptoms was achieved in 81% of patients with documented infections and in 74% of patients …

Thiamine for the treatment of nucleoside analogue-induced severe lactic acidosis

1999

Nucleoside analogue-induced lactic acidosis is an often fatal condition in patients with HIV. There is only one report of successful treatment with riboflavin. We describe a 30-year-old female with AIDS and nucleoside analogue-induced lactic acidosis that exacerbated shortly after introducing total parenteral nutrition and reversed within hours after the addition of thiamine. Successful treatment of nucleoside analogue-induced lactic acidosis with a high dose of thiamine supports the hypothesis that vitamin deficiency is an important cofactor in the development of this rare and unpredictable condition in patients with HIV. We suggest that high dose B-vitamins should be given to any patient …
