OKT4/OKT8 ratio in asymptomatic heroin addicts

The OKT4 (helper) and OKT8 (suppressor) lymphocytic subpopulations were enumerated in a sample of 60 asymptomatic drug addicts and in 17 controls. No significant differences in the ratio could be found that could not be explained by the action of HIV. It can be concluded that heroin itself was not responsible for any alteration in the T4/T8 ratio in the population considered.
