          Abstract

          Resumen Objetivo: Determinar la efectividad del uso de un protocolo de vitamina C, tiamina e hidrocortisona en shock séptico a las dosis empleadas en el estudio Marik. Método: Estudio observacional retrospectivo antes-después que compara dos grupos de pacientes con shock séptico: grupo tratamiento (GT), tratado con el protocolo, desde enero 2019 a mayo 2020, frente a un grupo control (GC) en un periodo previo. Los objetivos principales fueron la supervivencia a los 14 y a los 28 días. Resultados: Se incluyeron 91 pacientes, 44 en GC y 47 en GT. No se encontraron diferencias estadísticamente significativas en la supervivencia a los 14 ni a los 28 días ni en la duración de estancia hospitalaria ni en la Unidad de Reanimación (REA) (p>0,05). La variación de los valores de creatinina entre los días 1 y 4 presentó una mediana de -0,04 (RIC -0,24;0,8) en el GC frente a -0,3 del GT (RIC -0,079;-0,03), p<0,05. Los valores de procalcitonina descendieron en el 27,3% de los pacientes del GC frente al 91,5% del GT (p<0,05). La necesidad de soporte vasoactivo con noradrenalina fue del 93% GC vs 76,6% GT en el día 2; 75% GC vs 55,3% GT en el día 3; 50% GC vs 27,7% GT en el día 4 (p<0,05). Conclusiones: Los datos de nuestro estudio muestran un beneficio limitado del uso del protocolo en pacientes con shock séptico, pero son necesarios estudios de mayor reclutamiento con un diseño prospectivo randomizado para asegurar el beneficio real y/o dosis óptimas.

          Abstract Objective: To determine the effectiveness of using a protocol of vitamin C, thiamine and hydrocortisone for the treatment of septic shock at the doses used in the Marik study. Methods: Retrospective observational before-after study comparing two groups of patients with septic shock: treatment group (GT), treated with the protocol, between January 2019 and May 2020, versus a control group (GC) in a previous period. The primary outcomes were 14-Day and 28-Day Survival. Results: 91 patients were included, 44 in GC and 47 in GT. No statistically significant differences were found in 14day and 28-day survival, in length of hospital or Resuscitation Unit (REA) stay (p>0.05). The median creatinine variation between days 1 and 4 was -0.04 (IQR -0.24;0.8) in the GC vs -0.3 in the GT (IQR -0.079; -0.03) (p<0.05). Procalcitonin values decreased in 27.3% of GC versus 91.5% of GT (p<0.05). The need for vasoactive drugs (noradrenaline) was 93% in GC vs 76.6% GT on day 2; 75% GC vs 55.3% GT on day 3; 50% GC vs 27.7% GT on day 4 (p<0.05). Conclusions: Our results show a limited benefit of the use of the protocol in patients with septic shock, but larger recruitment studies with a prospective randomized design are needed to ensure real benefit and/or optimal doses.

            Effect of high-dose Ascorbic acid on vasopressor's requirement in septic shock

            Objective: Effects of ascorbic acid on hemodynamic parameters of septic shock were evaluated in nonsurgical critically ill patients in limited previous studies. In this study, the effect of high-dose ascorbic acid on vasopressor drug requirement was evaluated in surgical critically ill patients with septic shock. Methods: Patients with septic shock who required a vasopressor drug to maintain mean arterial pressure >65 mmHg were assigned to receive either 25 mg/kg intravenous ascorbic acid every 6 h or matching placebo for 72 h. Vasopressor dose and duration were considered as the primary outcomes. Duration of Intensive Care Unit (ICU) stay and 28-day mortality has been defined as secondary outcomes. Findings: During the study period, 28 patients (14 in each group) completed the trial. Mean dose of norepinephrine during the study period (7.44 ± 3.65 vs. 13.79 ± 6.48 mcg/min, P = 0.004) and duration of norepinephrine administration (49.64 ± 25.67 vs. 71.57 ± 1.60 h, P = 0.007) were significantly lower in the ascorbic acid than the placebo group. No statistically significant difference was detected between the groups regarding the length of ICU stay. However, 28-day mortality was significantly lower in the ascorbic acid than the placebo group (14.28% vs. 64.28%, respectively; P = 0.009). Conclusion: High-dose ascorbic acid may be considered as an effective and safe adjuvant therapy in surgical critically ill patients with septic shock. The most effective dose of ascorbic acid and the best time for its administration should be determined in future studies.

              Ascorbic acid, corticosteroids, and thiamine in sepsis: a review of the biologic rationale and the present state of clinical evaluation

              The combination of thiamine, ascorbic acid, and hydrocortisone has recently emerged as a potential adjunctive therapy to antibiotics, infectious source control, and supportive care for patients with sepsis and septic shock. In the present manuscript, we provide a comprehensive review of the pathophysiologic basis and supporting research for each element of the thiamine, ascorbic acid, and hydrocortisone drug combination in sepsis. In addition, we describe potential areas of synergy between these therapies and discuss the strengths/weaknesses of the two studies to date which have evaluated the drug combination in patients with severe infection. Finally, we describe the current state of current clinical practice as it relates to the thiamine, ascorbic acid, and hydrocortisone combination and present an overview of the randomized, placebo-controlled, multi-center Ascorbic acid, Corticosteroids, and Thiamine in Sepsis (ACTS) trial and other planned/ongoing randomized clinical trials.
