AB OBJECTIVE: To analyze the relationships between blood trace elements and
beta 2 microglobuline levels in the 2 years follow-up of HIV infected
patients with respect to the clinical evolution. METHODS: The study
group consisted of 148 patients (36 females and 112 males, age: 33 +/- 9
years) at various stages of HIV infection. Subjects exhibited no severe
renal disease or liver disease or hypoalbuminemia. 30 age cross-matched
healthy volunteers subjects (11 females, 19 males) served as controls.
Serum (zinc: Zn, selenium: Se, copper: Cu) levels, beta 2 microglobuline
(B2M) concentrations and CD4 and CD8 counts were examined. RESULTS: In
the HIV infected group, the decrease in Se and Zn levels as well as the
rise of B2M concentrations are progressive with the severity of the
disease. The Cu concentrations were within the normal range in 84% of
cases. Moreover, significant negative correlations were observed
between: B2M and CD4/CD8 ratio, B2M and CD4 expressed in %, B2M and Zn
values, B2M and Se values. There was also a negative relation between Se
and Zn concentrations. No relationship between all the different
parameters was found in control group. According to the clinical
evolution in the 2 ensuing years, similar observations were found one
year later in survival patients where as no correlation was observed in
subjects who died in the following 12 months (24 and 10 subjects died
respectively in the next 12 and 24 months). CONCLUSION: HIV patients
exhibited relationship between specific and nonspecific markers of
immune system activity and trace element status which are not observed
in HIV seronegative subjects. These correlations seems to reflect the
immune dysregulation as well as an increased oxydative stress and an
accelerated HIV replication. By resulting from a total immune
derangement associated with opportunistic infections and/or
gastrointestinal diseases, the lack of all the correlations between the
different parameters in patients with survival < 1 year argues for a
increased risk factor of unfavorable evolution.
