This study aimed to identify septic phenotypes in patients receiving vitamin C, hydrocortisone, and thiamine using temperature and white blood cell count. Data were obtained from septic shock patients who were also treated using a vitamin C protocol in a medical intensive care unit. Patients were divided into groups according to the temperature measurements as well as white blood cell counts within 24 h before starting the vitamin C protocol. In the study, 127 patients included who met the inclusion criteria. In the cohort, four groups were identified: &ldquo:Temperature &ge:37.1 °:C, white blood cell count &ge:15.0 1000/mm3&rdquo: (group A: n = 27), &ldquo:&ge:37.1 °:C, <:15.0 1000/mm3&rdquo: (group B: n = 30), &ldquo:<:37.1 °:C, &ge:15.0 1000/mm3&rdquo: (group C: n = 35) and &ldquo:<:37.1 °:C, <:15.0 1000/mm3&rdquo: (group D: n = 35). The intensive care unit mortality rates were 15% for group A, 33% for group B, 34% for group C, and 49% for group D (p = 0.051). The temporal improvement in organ dysfunction and vasopressor dose seemed more apparent in group A patients. Our results suggest that different subphenotypes exist among sepsis patients treated using a vitamin C protocol, and clinical outcomes might be better for patients with the hyperinflammatory subphenotype.
