- Interesting article. The only person who died was the one who received
- immunosuppressive treatment (prednisolone and cyclophosphamide) for an
- autoimmune disease. I am not saying that this particular article proves
- anything one way or the other, but it is just another piece in the
- puzzle.

- Abstract: There have been reported cases of long-term symptomless human
- immunodeficiency virus type 1 (HIV-1) infection, but it is not clear
- whether the benign course of infection was due to host, viral, or other
- unknown factors. During follow-up of subjects with transfusion-acquired
- HIV-1 infection in New South Wales, Australia, we identified a group of
- 6 subjects who had been infected through a single common donor. We were
- therefore able to study the contributions of various factors to the
- course of infection. Throughout follow-up (range 6.8-10.1 years after
- infection), 5 of the recipients and the donor (last follow-up 10.2 years
- after infection of the first recipient) remained clinically free of
- symptoms, with normal CD4 cell counts and no p24 antigenaemia. HIV-1 was
- isolated from only 1 recipient; the isolate did not induce syncytia in a
- SUPT1 co-culture assay and had a limited in-vitro host range. 1 infected
- recipient (who had received extensive immunosuppressive treatment for
- systemic lupus erythematosus) developed Pneumocystis carinii pneumonia
- and died 4.3 years after infection. The frequency of progression to AIDS
- or a CD4 cell count below 0.50 x 10(9)/l was significantly lower among
- the 6 subjects with a common donor (1/6) than among 101 other HIV-
- infected transfusion recipients for whom data from 7 years of follow-up
- were available (94/101; p less than 0.0001). These findings suggest that
- the subjects were infected by a less virulent strain of HIV-1. The
- identification of this group of subjects should stimulate a search for
- other similar groups, which will provide important information on the
- immunopathogenesis of HIV-1 disease.
