New Atypical Manifestations and Prognostic Factors of Vibrio vulnificus Infection: a 10-Year Retrospective Study
JAPANESE JOURNAL OF INFECTIOUS DISEASES(2021)
Abstract
Vibrio vulnificus (V. vulnificus) infection is rare but potentially fatal. This study explored new atypical manifestations and prognostic factors of V. vulnificus-infected patients during hospitalization. We retrospectively reviewed the medical records of 33 patients diagnosed with V. vulnificus infection in Guangdong Province, China between 2010 and 2020. Multiple logistic regression and receiver operating characteristic (ROC) curve analyses were performed. The new atypical manifestations included cholangitis, urinary tract infection, and suppurative otitis media. Eleven of the 33 (33.3%) V. vulnificus-infected patients eventually died. Univariate analysis showed that patients with cardio-cerebrovascular diseases, lower platelet counts, and higher levels of C-reactive protein and procalcitonin (PCT) had statistically higher mortality. However, multivariate analysis showed that only the PCT level (P = 0.036) was statistically significant. In addition, the area under the ROC value estimate for PCT was 0.8816 (95% confidence interval (CI), 0.759-1.000; P = 0.0009). More than half of the patients with V. vulnificus infection died when PCT was > 20 ng/mL, while no patient died when PCT was <= 20 ng/mL. This study found new atypical manifestations of V. vulnificus infection. In addition, PCT was an effective and independent predictor of mortality in patients with V. vulnificus infection, allowing clinicians to conduct early risk stratification and determine the best therapeutic strategies.
