Background: Sleep is essential for the maintenance of an intact immune function. Patients with sleep apnoea experience frequent sleep interruption due to apnoea-related arousals, possibly adversely impacting their immunity and affecting their outcomes when confronting sepsis. This case-control study aimed to compare the outcomes of sepsis patients with and without sleep apnoea., Methods: From 2000 to 2009, 168 sleep apnoea patients who were first admitted for sepsis were identified from the Taiwan National Health Insurance Research Database. Also, 672 sepsis patients without sleep apnoea, who were matched by age, gender and Charlson's comorbidity index scores, served as controls. Hospital outcomes of the two groups were compared. Binary logistic regression was employed for multivariate analysis., Results: The mortality rates of sepsis patients with and without sleep apnoea were 60.1% and 47.9%, respectively (P = 0. 005). After multivariate adjustment, sleep apnoea (OR: 1.805, 95% CI: 1.227-2.656, P = 0.003), presence of shock (OR: 3.600, 95% CI: 2.144-6.046, P < 0.001) and number of organs with dysfunction (OR: 1.591, 95% CI: 1.087-2.329, P = 0.017) were found to be independently associated with mortality. Sleep apnoea patients who needed continuous positive airway pressure treatment had an even higher risk of mortality., Conclusions: Sepsis patients with sleep apnoea may have poorer hospital outcomes than those without sleep apnoea., (© 2013 Stichting European Society for Clinical Investigation Journal Foundation.

Background: In recent years, intensive care for cancer patients has improved and treatment of critically ill cancer patients has become increasingly aggressive over time. However, not all cancer patients would benefit from aggressive care, especially those with late-stage cancer., Objective: We aimed to investigate the outcome of late-stage lung cancer patients with sepsis-related respiratory failure and identify predictors of mortality., Methods: From 2007 to 2008, consecutive stage III and IV lung cancer patients admitted to an intensive care unit (ICU) of a teritiary medical center in Taiwan for sepsis-related respiratory failure were retrospectively enrolled. Data at baseline and upon ICU admission were collected. In-hospital survival was analyzed. Variables of the survivors to hospital discharge and patients who died were compared by uni- and multivariate analyses., Results: Seventy patients were enrolled. During a mean follow-up period of 30.10 days, 29 (41.4%) patients survived to hospital discharge and 41(58.6%) died. Compared with the survivors, the patients who died had poor performance status, lower serum albumin level, higher percentage of disseminated intravascular coagulation, and more severe organ dysfunction as disclosed by higher Sequential Organ Failure Assessment (SOFA) scores. Multivariate analyses revealed that SOFA score (p=0.026) was the only independent predictor of mortality; 44.8 % (13/29) of survivors were weaned from ventilator during hospitalization., Conclusion: Among late-stage lung cancer patients with sepsis-related respiratory failure, those with lower SOFA scores seemed to have better survival rate and may benefit from intensive care in the ICU. Early palliative care should be considered for all patients with advanced lung cancer, and hospice care is suggested for those with sepsis-respiratory failure and high SOFA scores.

Sex hormones have diverse immunomodulatory effects that may be involved in the pathogenesis of sepsis. However, the roles of serum sex hormones in predicting outcomes and the severity of organ dysfunction, especially acute kidney injury (AKI), in septic shock patients remains controversial. We prospectively enrolled 107 clinically diagnosed pneumonia-related septic shock patients and serum sex hormone levels were measured on the day of shock onset. The aim of the present study was to investigate the predictive values of serum sex hormones levels for 28-day mortality and organs dysfunction, especially AKI. Compared with survivors, serum levels of progesterone (p<0.001) and estradiol (p<0.001) were significantly elevated in non-survivors. In multivariate Cox regression analysis, serum level of estradiol >40 pg/mL (p = 0.047) and APACHE II score ≥25 (p = <0.001) were found to be independent predictors of day 28 mortality. Inclusion of estradiol levels further enhanced the ability of APACHE II scores to predict survival in patients with high mortality risk. A serum level of estradiol >40 pg/mL was also an independent predictor of concomitant AKI (p = 0.002) and correlated well with severity of renal dysfunction using RIFLE classification. Elevated serum estradiol levels also predicted the development of new AKI within 28 days of shock onset (p = 0.013). In conclusion, serum estradiol levels appear to have value in predicting 28-day mortality in septic shock patients. Increased serum estradiol levels are associated with higher severity of concomitant AKI and predict development of new AKI. [ABSTRACT FROM AUTHOR]
