 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.
