Abstract
Microvascular dysfunctions are associated with poor prognosis in sepsis. However, the potential role of clinical assessment of peripheral ischemic microvascular reserve (PIMR), a parameter that characterizes the variation of peripheral perfusion index (PPI) after brief ischemia of the upper arm, as a tool to detect sepsis-induced microvascular dysfunction and for prognostic enrichment has not been established. To address this gap, this study investigated the association of high PIMR with mortality over time in patients with sepsis and its subgroups (with and without shock) and peripheral perfusion (capillary-refill time). This observational cohort study enrolled consecutive septic patients in four Intensive-care units. After fluid resuscitation, PIMR was evaluated using the oximetry-derived PPI and post-occlusive reactive hyperemia for two consecutive days in septic patients. Two hundred and twenty-six patients were included-117 (52%) in the low PIMR group and 109 (48%) in the high PIMR group. The study revealed differences in mortality between groups on the first day, which was higher in the high PIMR group (RR 1.25; 95% CI 1.00-1.55; p = 0.04) and maintained its prognostic significance after multivariate adjustment. Subsequently, this analysis was made for sepsis subgroups and showed significant differences in mortality only for the septic-shock subgroup, with was higher in the high PIMR group (RR 2.14; 95% CI 1.49-3.08; p = 0.01). The temporal ΔPPI peak values (%) analyses did not demonstrate maintenance of the predictive value over the first 48 h in either group (p > 0.05). A moderate positive correlation (r = 0.41) between ΔPPI peak (%) and capillary-refill time (s) was found within the first 24 hours of diagnosis (p < 0.001). In conclusion, detecting a high PIMR within 24 h appears to be a prognostic marker for mortality in sepsis. Furthermore, its potential as a prognostic enrichment tool seems to occur mainly in septic shock.

Abstract
Microcirculatory disorders have been consistently linked to the pathophysiology of sepsis. One of the major organs affected is the kidneys, resulting in sepsis-associated acute kidney injury (SA-AKI) that correlates considerably with mortality. However, the potential role of clinical assessment of peripheral perfusion as a possible tool for SA-AKI management has not been established. To address this gap, the purpose of this study was to investigate the prevalence of peripheral hypoperfusion in SA-AKI, its association with mortality, and fluid balance. This observational cohort study enrolled consecutive septic patients in the Intensive Care Unit. After fluid resuscitation, peripheral perfusion was evaluated using the capillary filling time (CRT) and peripheral perfusion index (PI) techniques. The AKI was defined based on both serum creatinine and urine output criteria. One hundred and forty-one patients were included, 28 (19%) in the non-SA-AKI group, and 113 (81%) in the SA-AKI group. The study revealed higher peripheral hypoperfusion rates in the SA-AKI group using the CRT (OR 3.6; 95% CI 1.35-9.55; p < 0.05). However, this result lost significance after multivariate adjustment. Perfusion abnormalities in the SA-AKI group diagnosed by both CRT (RR 1.96; 95% CI 1.25-3.08) and PI (RR 1.98; 95% CI 1.37-2.86) methods were associated to higher rates of 28-day mortality (p < 0.01). The PI's temporal analysis showed a high predictive value for death over the first 72 h (p < 0.01). A weak correlation between PI values and the fluid balance was found over the first 24 h (r = - 0.20; p < 0.05). In conclusion, peripheral perfusion was not different intrinsically between patients with or without SA-AKI. The presence of peripheral hypoperfusion in the SA-AKI group has appeared to be a prognostic marker for mortality. This evaluation maintained its predictive value over the first 72 hours. The fluid balance possibly negatively influences peripheral perfusion in the SA-AKI.
