Unique Identifier : AIDSLINE MED/94133106 AB C57/BL/6 mice infected with LP-BM5 MuLV virus developed an AIDS-like disease (MAIDS) with splenomegaly, leukopenia, thrombocytopenia, anemia, decreased numbers of helper/inducer and suppressor/cytotoxic T-cells and decreased production of interferon alpha. We have shown previously that HIV-associated Kaposi's sarcoma tissue contains high levels of prostaglandin E2 (PgE2), and this inhibits interferon synthesis through a cAMP-dependent second-messenger process. In this study we treated groups of MAIDS-infected mice with combinations of pentoxifylline, an agent which increases cAMP and inhibits phosphodiesterases, and sodium meclofenamic acid, a PgE2 inhibitor. Treated mice showed: 1) significantly higher total leukocyte and platelet counts, 2) higher total L3T4+ (helper/inducer) and Lyt-2+ (suppressor-cytotoxic) T-cell population. Pathologic examination also showed significantly less hepatosplenomegaly and lymphadenopathy in animals treated with pentoxifylline and meclofenamic acid. Partly, PgE2-induced suppression of interferon alpha production may mediate expression of retrovirus infection in this murine model of AIDS.
