Objective:
The purpose of this study is to study laboratory indicators for the identification of hand, foot, and mouth disease (HFMD) severity.
Methods:
We searched PubMed, Embase, and the Web of Science for literature that was published before May 2022. The main results are presented as forest plots. Subgroup analyses, sensitivity analyses, and publication bias were also performed.
Results:
Our study indicated that white blood cells (WBC) (95%CI: 0.205-0.778), blood glucose (95%CI: 0.505-0.778), lymphocytes (95%CI: 0.072-0.239), creatinine (95%CI: 0.024-0.228), interleukin (IL)-2 (95%CI: 0.192-1.642), IL-6 (95%CI: 0.289-0.776), IL-8 (95%CI: 0.499-0.867), IL-10 (95%CI: 0.226-0.930), interferon-γ (IFN-γ) (95%CI: 0.193-2.584), tumor necrosis factor-α (TNF-α) (95%CI: 1.078-2.715), and creatine kinase MB isoenzyme (CK-MB) (95%CI: 0.571-1.459) were associated with an increased risk of HFMD severity, and the results of the sensitivity analysis of these indicators were stable and free of publication bias.
Conclusions:
Our results suggest that various deleterious immune and metabolic changes can increase the risk of HFMD severity, which can provide a basis for predicting the prognosis and useful evidence for clinicians to manage patients efficiently.
