Cytomegalovirus (CMV) infections is a severe infection in patients of rheumatic disease treated with corticosteroid and immunosuppressive agents. Ganciclovir is the main therapy in CMV infection, accompanied with diverse side effects, including neutropenia, anemia, disorder of renal function and so on, which are also common symptoms of rheumatic diseases. Additionally, prolonged antiviral treatment may delay recovery of virus, specific immune responses, resulting in an increasing of late-onset CMV disease.
IL-2 is a pleotropic cytokine which can promote the proliferation and function of CD8+ T cells and NK cells through the combination with IL-2 receptor. Recently, several studies have revealed that low dose IL-2 is an effective and safe therapy for autoimmune disease. In systemic lupus erythematous patients, additionally, patients treated with low-dose IL-2 had lower incidence of infection with increased percentages of natural killer (NK) cells.
In this prospective clinical trial, we propose to assess the effective and safety of low-dose IL-2 combined with ganciclovir in the treatment of CMV infection. Meanwhile, we will assess the immune response of after IL-2 treatment.
In rheumatic diseases, CMV infection are more frequent in patients after corticosteroid pulse treatment and long-term treatment of corticosteroid and immunosuppressor.
If patients are eligible, which CMV-DNA are more than 10\^3 copies, it will be randomly distributed in low-dose IL-2 and ganciclovir group, or ganciclovir group. Low-dose IL-2 is defined as 1 million IU per day subcutaneously, The CMV-DNA levels will be monitored until it turned out to be negative. In this period, we will simultaneously monitor the immune response in regard to CMV infection, including innate immune response, such as IFN-γ, TNF-α, natural killer cells, and adaptive immune response, such as CMV specific CD8+ T cells, T helper cells and so on.
We will follow these patients for at least 3 months after drug withdrawal. If patient belonging to any of these two groups develops a viral infection, then the patient will receive treatment with ganciclovir.
