本研究の目的は,尿酸(UA)が2019年新型コロナウイルス症(COVID-19)の予後因子および重要なマーカーとして独立して作用するかどうかを探ることである.武漢の4つの指定病院で、COVID-19が確認された540人の患者を含む多施設、レトロスペクティブ、観察研究を実施した。人口統計学的データ、臨床データ、検査データを収集し、分析した。主要評価項目は,COVID-19 患者の院内死亡であった.死亡した患者の入院時のUA濃度(adUA)および入院中の最低尿酸濃度(lowUA)は,生存者のそれよりも有意に低かった。多変量ロジスティック回帰分析の結果、lowUAの濃度(OR 0.986、95%CI 0.980-0.992、p<0.001)は、院内死亡のリスクを独立して予測できることがわかった。lowUAの濃度が低い群の平均生存期間は,他の群に比べて有意に短かった.lowUAが≦166µmol/Lの場合、院内短期死亡率を予測する感度は76.9%(95%CI 68.5-85.1%)、特異度は74.9%(95%CI 70.3-78.9%)でした。今回のレトロスペクティブ研究では、COVID-19の重症患者において、入院中のUAの最低濃度が予後の指標および重症度のマーカーとして使用できることが判明しました。
The purpose of this study is to explore whether uric acid (UA) can independently act as a prognostic factor and critical marker of the 2019 novel corona virus disease (COVID-19). A multicenter, retrospective, and observational study including 540 patients with confirmed COVID-19 was carried out at four designated hospitals in Wuhan. Demographic, clinical, laboratory data were collected and analyzed. The primary end point was in-hospital death of patients with COVID-19. The concentration of admission UA (adUA) and the lowest concentration of uric acid during hospitalization (lowUA) in the dead patients were significantly lower than those in the survivors. Multivariate logistic regression analysis showed the concentration of lowUA (OR 0.986, 95% CI 0.980-0.992, p < 0.001) was able to independently predict the risk of in-hospital death. The mean survival time in the low-level group of lowUA was significantly lower than other groups. When lowUA was ≤ 166 µmol/L, the sensitivity and specificity in predicting hospital short-term mortality were 76.9%, (95% CI 68.5-85.1%) and 74.9% (95% CI 70.3-78.9%). This retrospective study determined that the lowest concentration of UA during hospitalization can be used as a prognostic indicator and a marker of disease severity in severe patients with COVID-19.
