Abstract Incubation of serum and plasma samples at 56 degrees C for 30 min inactivates the HTLV-III virus. We assessed the effect of this procedure on results of routine biochemical tests by dividing samples of serum and plasma into two, heat-treating one while the other remained at room temperature. Samples were then analyzed in an SMA 16/60, an Astra-8, an Analox glucose analyzer, a Cobas Bio centrifugal analyzer, and manually for salicylate and acetaminophen (paracetamol). Most of the differences produced by heat treatment were not clinically significant, although heated samples proved unsuitable for use in assay of some commonly measured enzymes. Serum evidently is preferable to plasma for this procedure, and heat-treated serum samples can validly be used for most routine analyses. Thus this procedure makes safer the analysis of samples from patients with suspected or proven acquired immune deficiency syndrome (AIDS).

Acquired Immune Deficiency

Abstract Monoclonal and oligoclonal banding has been observed in electrophoretograms of serum, cerebrospinal fluid, and urinary protein from patients infected with the human immunodeficiency virus (HIV). This is the first report of kappa oligoclonal banding in the protein electrophoretograms for urine but not for serum of two patients with the acquired immune deficiency syndrome (AIDS). Both patients had proteinuria, but only one had the nephrotic syndrome and renal failure. Serum oligoclonal banding in HIV-infected patients occurs much more frequently than in age-matched controls and may be detected before AIDS or lymphadenopathy syndrome evolves. The use of oligoclonal banding as a marker for HIV infection is currently under investigation. Urine as well as serum samples should be included in this research.

The subtypes of human immunodeficiency virus type 1 (HIV–1) group M exhibit a remarkable similarity in their between–subtype distances, which we refer to as high synchrony. The shape of the phylogenetic tree of these subtypes is referred to as a sunburst to distinguish it from a simple star phylogeny. Neither a sunburst pattern nor a comparable degree of symmetry is seen in a natural process such as in feline immunodeficiency virus evolution. We therefore have undertaken forward–process simulation studies employing coalescent theory to investigate whether such highly synchronized subtypes could be readily produced by natural Darwinian evolution. The forward model includes both classical (macro) and molecular (micro) epidemiological components. HIV–1 group M subtype synchrony is quantified using the standard deviation of the between–subtype distances and the average of the within–subtype distances. Highly synchronized subtypes and a sunburst phylogeny are not observed in our simulated data, leading to the conclusion that a quasi–Lamarckian, punctuated event occurred. The natural transfer theory for the origin of human acquired immune deficiency syndrome (AIDS) cannot easily be reconciled with these findings and it is as if a recent non–Darwinian process took place coincident with the rise of AIDS in Africa.
