BACKGROUND: Every year, a large number of people undergo kidney transplants because of various reasons leading to renal failure. These patients usually have low immunoglobulin levels due to the use of immunosuppressive drugs. In recent years, the COVID-19 pandemic has been a major global health risk. Patients who are immunocompromised or who have diabetes are especially at risk.
METHODS: In this study, we enrolled 156 patients who had undergone kidney transplant and had received 2 doses of Sinopharm/BIBP-CorV. The serum antibody levels against COVID-19 spike glycoprotein (immunoglobulin [Ig] G and IgM) were measured using a sandwich enzyme-linked immunosorbent assay kit to evaluate whether different immunosuppressive drugs could affect the body's response to the said vaccine.
RESULTS: We found that only patients receiving Rapamune had increased IgM secondary to COVID-19 vaccine. None of the immunosuppressive drugs in this study have shown a positive correlation with increased IgG levels. The only factor that showed a significant effect on both IgM and IgG was a positive history of COVID-19, which was correlated with increased levels of serum IgG/M.
CONCLUSIONS: Only patients treated with Rapamune showed an acute immune reaction to the vaccine in the form of positive serum IgM levels, and no rise of serum IgM antibody was observed in COVID-19-naive patients. Patients who had a previous history of COVID-19 infection showed an elevated serum IgM and IgG level, suggesting that vaccines in general and Sinopharm/BIBP-CorV in particular are not enough to ensure immunity against COVID-19 in transplant recipients. We recommend further studies using different types of vaccines and immunosuppressive drugs.
