ABSTRACT:
The present invention is directed to methods of treating CD4+ T cell lymphopenia in HIV-infected patients. The methods include administering an effective mount of adenosine deaminase or related enzymatic material to a patient in need thereof. In preferred aspects of the invention, the method is employed in conjunction with HIV-infected patients having CD4+ T cell levels of less than about 200/.mu.l. Effective amounts of the enzyme range from about 5 to about 50 IU/kg/week. In one particularly preferred aspect of the invention, the adenosine deaminase is conjugated to one or more strands of polyethylene glycol to prolonged activity in vivo.
