Necrotizing soft tissue infections in critically ill neutropenic patients: a French multicentre retrospective cohort study

Abstract Background Necrotizing soft tissue infections (NSTIs) are rare life-threatening bacterial infections. Few data are available regarding neutropenic patients with NSTIs. Our objectives were to describe the characteristics and management of neutropenic patients with NSTIs in intensive care units (ICUs). We conducted a retrospective multicentre cohort study in 18 ICUs between 2011 and 2021. Patients admitted with NSTIs and concomitant neutropenia at diagnosis were included and compared to non-neutropenic patients with NSTIs. The relationship between therapeutic interventions and outcomes was assessed using Cox regression and propensity score matching. Results 76 neutropenic patients were included and compared to 165 non-neutropenic patients. Neutropenic patients were younger (54 ± 14 vs 60 ± 13 years, p = 0.002) and had less lower limb (44.7% vs 70.9%, p < 0.001) and more abdomino-perineal NSTIs (43.4% vs 18.8%, p < 0.001). Enterobacterales and non-fermenting gram-negative bacteria were the most frequently isolated microorganisms in neutropenic patients. In-hospital mortality was significantly higher in neutropenic than in non-neutropenic patients (57.9% vs 28.5%, p < 0.001). Granulocyte colony-stimulating factor (G-CSF) administration was associated with a lower risk of in-hospital mortality in univariable Cox (hazard ratio (HR) = 0.43 95% confidence interval (CI) [0.23–0.82], p = 0.010) and multivariable Cox (adjusted HR = 0.46 95% CI [0.22–0.94], p = 0.033) analyses and after overlap propensity score weighting (odds ratio = 0.25 95% CI [0.09; 0.68], p = 0.006). Conclusions Critically ill neutropenic patients with NSTIs present different clinical and microbiological characteristics and are associated with a higher hospital mortality than non-neutropenic patients. G-CSF administration was associated with hospital survival

Long-term quality of life in adult patients surviving purpura fulminans: an exposed-unexposed multicenter cohort study

International audienceBACKGROUND : Long-term health-related quality of life (HR-QOL) of patients surviving the acute phase of purpura fulminans (PF) has not been evaluated.METHODS : This was a French multicenter exposed-unexposed cohort study enrolling patients admitted in 55 intensive care units (ICUs) for PF from 2010 to 2016. Adult patients surviving the acute phase of PF (exposed group) were matched 1:1 for age, sex, and Simplified Acute Physiology Score II with septic shock survivors (unexposed group). HR-QOL was assessed during a phone interview using the 36-Item Short-Form Health Survey (SF-36) questionnaire, the Hospital Anxiety and Depression (HAD) scale, the Impact of Event Scale-Revised (IES-R), and the activity of daily living (ADL) and instrumental ADL (IADL) scales. The primary outcome measure was the physical component summary (PCS) of the SF-36 questionnaire.RESULTS : Thirty-seven survivors of PF and 37 of septic shock were phone-interviewed at 55 (interquartile range [IQR], 35-83) months and 44 (IQR, 35-72) months, respectively, of ICU discharge (P = .23). The PCS of the SF-36 was not significantly different between exposed and unexposed patients (median, 47 [IQR, 36-53] vs 54 [IQR, 36-57]; P = .18). There was also no significant difference between groups regarding the mental component summary of the SF-36, and the HAD, IES-R, ADL and IADL scales. Among the 37 exposed patients, those who required limb amputation (n = 12/37 [32%]) exhibited lower PCS (34 [IQR, 24-38] vs 52 [IQR, 42-56]; P = .001) and IADL scores (7 [IQR, 4-8] vs 8 [IQR, 7-8]; P = .021) compared with nonamputated patients.CONCLUSIONS : Long-term HR-QOL does not differ between patients surviving PF and those surviving septic shock unrelated to PF. Amputated patients have an impaired physical HR-QOL but a preserved mental healt
