ABSTRACT
Objective:
To evaluate the effectiveness and safety of coronavirus disease 2019 (COVID-19) vaccines for dialysis patients with chronic kidney disease.Methods:
PubMed, Medline, Embase databases and CNKI, VIP, Wanfang databases were searched systematically. The deadline was April 25, 2022. The search terms included haemodialysis, peritoneal dialysis, vaccine, seroresponse, COVID-19, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The main outcome included the positive rate after vaccination, antibody titer, antibody changes during follow-up, infection rate of SARS-CoV-2, hospitalization rate and mortality.Results:
A total of 154 195 patients were analyzed in 26 studies. The results of meta-analysis showed that the positive rate of serum IgG antibody in patients with chronic kidney disease was 48% after the first dose of vaccine, 89% and 96% after the second dose and third dose, respectively. After vaccination with COVID-19 vaccines, there was no significant difference in serum antibody and titer between hemodialysis patients and peritoneal dialysis patients. However, compared with the healthy control group, the antibody positive rate and antibody titer of dialysis patients after vaccination were lower (both P<0.05). In the follow-up, the antibody positive rate at the third month decreased by 12% compared with at the first month, at the sixth month decreased by 15% compared with at the third month, and at the sixth month decreased by 20% compared with at the first month. The serum antibody positive rate after the third dose of vaccine increased by 38% ( RR=1.38, 95% CI 1.12-1.70, P<0.001), and the antibody titer increased significantly ( SMD=1.46, 95% CI 0.31-2.61, P<0.001). Although the vaccines could not reduce the infection rate of SARS-CoV-2 in dialysis patients, it could significantly reduce the hospitalization rate and mortality after infection.Conclusions:
After vaccination with COVID-19 vaccines, dialysis patients can produce strong serum antibodies, which can reduce the hospitalization rate and mortality after SARS-CoV-2 infection. However, the duration of antibody is short and the titer level is low, so it is necessary to timely vaccinate booster vaccine dose to obtain stronger immunogenicity.
