Description of intervention(s) / exposure
Patients exposed to sepsis or septic shock will be monitored for thiamine deficiency. Therefore transketolase levels will be measured at 4 timepoints to determine (relative) thiamine deficiency. Also lactate levels will be observed in each patient, to review any relationship between thiamine deficiency and lactate levels.

2) 24 hours after ICU admission [primary timepoint]
3) 48 hours after ICU admission
4) 72 hours after ICU admission

Eligibility
Key inclusion criteria
Sepsis, defined as an infection complicated by organ dysfunction, identified as SOFA score greater than or equal to 2 or a change in SOFA greater than or equal to 2 point from baseline,
OR
Septic shock, defined as sepsis and persistent hypotension despite adequate fluid resuscitation, as seen by:
1. Vasopressors required to maintain MAP greater than or equal to 65 mmHg
AND
2. Serum lactate level greater than 2 mmol/L
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
<18 years of age;
Pregnancy;

Statistical methods / analysis
Individual variables will be summarised by mean (SD), median (IQR) or count (%) as indicated. Thiamine levels will be reported as absolute levels at measured time points, and as relative change in concentration across the 72 hour period. Univariate analysis will be conducted to measure association between thiamine concentration, physiological variables and lactate concentrations, with statistically significant results being used to conduct multivariate analysis. Statistical analysis will be performed using SPSS 24 and/or StataMP 15 software.

Summary
Brief summary
This study will determine the prevalence and incidence of thiamine deficiency in patients admitted to the intensive care unit with sepsis and septic shock, and measure association with peak lactate concentrations at admission, and within 24, 48 and 72 hours of admission.
As a pilot epidemiological study, this project will help inform future studies of the role of thiamine and other nutritional deficiencies in the pathogenesis and management of septic shock, and will provide useful data for hypothesis generation and calculation of sample size for future studies.
