AB Murine immunodeficiency disease (MAIDS) induced with LP-BM5 strain of
MuLV is a disease that shows many similarities to human HIV-infection.
Lithium (Li) influences many aspects of immunohematopoietic cellular
proliferation and differentiation and is an antagonist to magnesium (Mg)
dependent reactions. We describe here results of in vivo studies
investigating the effects of Li and Mg (1 mmol placed in the drinking
water) treatment in MAIDS-infected mice. Viral control, Li and Mg
treated C57BL/6 mice were monitored for survival and MAIDS pathology.
Virus-treated mice were grouped to receive Li po as follows: (1) 48 hr
before virus; (2) at the same time as virus and (3) 5-wk postvirus. Mg
was given 5-wk postvirus. After 22 wk of observation, percent survival
was as follows: virus controls, 20%; Mg, 5 wk postvirus, 40%; Li, 5 wk
postvirus, 80%; Li, at the time of virus, 85%; and Li, 48 hr prior to
virus, 100% survival. Lymphoma, measured by splenomegaly (gms) was
significantly reduced: normal age-matched controls 0.1 +/- 0.01; virus
controls, 0.83 +/- 0.2, Mg, 5 wk postvirus, 1.47 +/- 0.12; Li, 5 wk
postvirus, 0.47 +/- 0.02; and Li, at the time of virus, 0.28 +/- 0.1 (p
value less than 0.01). These data suggest cations such as Mg and Li may
play an important role in MAIDS pathogenesis and also indicates Li may
be an efficacious agent in altering the pathogenesis and lymphoma
characteristic of this retroviral disease in mice.
