BackgroundSepsis and septic shock are severe medical conditions that can damage multiple organs with a higher risk of mortality. Recently, the combination of hydrocortisone, ascorbic acid and thiamine (HAT) was hypothesized to work synergistically to reverse septic shock and reduce mortality.AimTo ascertain the efficacy of HAT therapy and compare whether HAT therapy is more beneficial compared to the standard of care in sepsis and septic shock patients.MethodsPubMed, Clinicaltrials.gov, Scopus, Web of Science, Cochrane and Embase are databases that were used to identify trials that conducted a study of the combination of HAT in sepsis or septic shock.ResultsThere were 134 articles identified through a database search and 16 from other sources, which were subsequently reduced to 11 trials (six randomized trials and five non-randomized trials) that were deemed appropriate for inclusion in this review. Most of the outcomes from these studies focused on mortality, the need for renal replacement therapy, duration of vasopressor use, changes in Sequential Organ Failure Assessment score, procalcitonin clearance and lengths of intensive care unit stay.ConclusionDue to inconsistent results from clinical studies, the benefits of HAT therapy cannot be confirmed at this point in sepsis and septic shock. Currently, there are at least 20 randomized controlled trials testing HAT in various combinations and dosages in patients with severe sepsis and septic shock. The results of these studies are required before definitive conclusions can be made regarding the impact of this novel treatment strategy on the morbidity and mortality of patients with sepsis.
