Summary
Drug addicts with persistent lymphadenopathy showed immune system deficits. Thymopentin treatment partially restored immune cell function, improving T-lymphocyte counts and neutrophil activity.
Area of Science:
- Immunology
- Pharmacology
Background:
- Drug addicts with persistent generalized lymphadenopathy exhibit significant immunological abnormalities.
- These include an inverted OKT4/OKT8 lymphocyte ratio and impaired neutrophil function.
- Deficiencies in blastogenetic response and phagocytic/chemotactic capabilities against Candida albicans were observed.
Purpose of the Study:
- To evaluate the efficacy of Thymopentin in correcting immunological abnormalities in drug addicts with persistent generalized lymphadenopathy.
Main Methods:
- Treatment involved Thymopentin administration (50 mg s.c. 3 times/week for 3 weeks, repeated after 3 months).
- Immunological parameters, including OKT4+ lymphocyte counts, blastogenesis to PWM, and neutrophil chemotaxis, were assessed before and after treatment.
Main Results:
- Thymopentin treatment significantly improved OKT4+ lymphocyte counts (p<0.05).
- A significant enhancement in blastogenesis response to pokeweed mitogen (PWM) was observed (p<0.01).
- Neutrophil chemotaxis returned to normal values after the first treatment cycle.
Conclusions:
- Thymopentin demonstrates a capacity to partially restore immune function in drug addicts with persistent generalized lymphadenopathy.
- The treatment positively impacts T-lymphocyte populations and neutrophil activity, suggesting therapeutic potential.
