Thalidomide is increasingly being used as adjuvant therapy for
patients with mycobacterial and human immunodeficiency virus (HIV)
infections. The T-helper (Th)1 cytokine-Th2 cytokine balance critically determines the outcomes of these diseases. To obtain insight
into the effect of thalidomide on the capacity of lymphocytes to
produce Th1 and Th2 cytokines, six healthy volunteers received an oral
dose (400 mg) of thalidomide. Before and at 3, 6, and 24 h after
ingestion of thalidomide, peripheral blood mononuclear cells (PBMCs)
were isolated and stimulated for 24 h with the T-cell stimulant
staphylococcal enterotoxin B (SEB) or anti-CD3/CD28. In all six
volunteers ingestion of thalidomide was associated with enhanced SEB-
and anti-CD3/CD28-induced production of the Th1 cytokine gamma
interferon (P < 0.05) and a decrease in the level of
anti-CD3/CD28-induced interleukin-5 (IL-5) production (P < 0.05). The levels of IL-2 (Th1) and IL-4 (Th2)
released remained unchanged. These changes were accompanied by an
increase in the amount of IL-12p40 released by the PBMCs 6 h after
ingestion of thalidomide (P < 0.05). Thus, a single
oral dose of thalidomide causes a Th1-type response in healthy humans.
This finding offers a potential explanation for the positive effect of
thalidomide in patients with mycobacterial and HIV infections.
