Summary
Combined antiretroviral therapy (ART) efficiently suppresses viral replication and markedly decreases mortality among patients with HIV-1 infection/AIDS. While the advanced AIDS patients with CD4+T cell count less than 200 cells/L often develop seriously opportunistic infections (OIs), severe wasting syndrome, and other fatal complications, which are the major causes of death in these patients. There has been no effective immune therapy for advanced AIDS patients who had a high mortality rate even in the era of cART. This clinical trail is to inspect the efficiency of allogeneic adoptive immune therapy for advanced AIDS patients.
Description
Combined antiretroviral therapy (ART) efficiently suppress viral replication and dramatically decrease mortality of the disease in HIV-1/AIDS patients.1 While in cART naive patients with chronic human immunodeficiency virus-1 (HIV-1) infection often characterized by HIV-1 replication, immune activation and deficiency, which lead to profound and systematic inflammation and pathoglogical change, especially in the AIDS patients with CD4 T count less than 50/uL, who often develop deadly complications, which accounts for the major cause of death group in spite of cART era. Up-to-date, there are no effective immune interventions to restore host holistic immunity for advanced AIDS patients.
In pre-cARTera, HLA-matched lymphocytes or stem cell transplantation had been exploratively used in AIDS patients. However, this kind of therapy failed for immunological reconstitution due to the lack of antiviral therapy to suppress HIV-1 replication at that time. With the advent of cART, allogeneic HLA-matched or mismatched lymphocytes or stem cell transplantations were mainly used for AIDS patients with hematopoietic malignancies, the Berlin and London patients were the cured pateints. However, allogeneic transplantation can not be used outside the setting of hematopoietic malignancies. In addition, the high frequency of GVHD (Graft-versus-host disease) owning to a transient or long-lasting engraftment is inevitable.
Until now, there has been no report of effective immune therapy for late-stage AIDS patients with acquired immunodeficiency and severe opportunistic infections (OIs). The urgent challenge is how to efficiently restore the host holistic immunity in AIDS patients at late stage.
The investigators have recently developed a mismatched allogeneic adoptive immune therapy (AAIT) protocol in combination with cART, and found that the treatment was safety and tolerability in a phase I study. The purpose of this study is to further investigate the efficacy of allogeneic adoptive immune therapy (AAIT) for advanced AIDS patients. 120 patients received i.v. transfusion one round (2-3 times) of 2.0-3.0*10E8 cells/kg of MNSs as the treated group, all of these patients received the conventional cART treatment. In addition, the equal 120 patients received cART were used as control. The side effects, CD4 T cell numbers, HIV viral load, clinical symptoms improvement, control of opportunistic infections, AIDS-related events and non-AIDS related events will be evaluated during the 96-week follow up.
