Abstract. Background:. Sepsis is a serious disease caused by infection. Aminophylline has anti-asthma and anti-inflammatory effects. We aimed to explore the safety and effect of aminophylline in sepsis. Methods:. We conducted a clinical randomized controlled trial involving 100 patients diagnosed with sepsis within 48 h after intensive care unit (ICU) admission in two sites. All patients were randomized in a 1:1 ratio to receive standard therapy with or without aminophylline. The primary clinical outcome was all-cause mortality at 28 days. Results:. From September 27, 2018 to February 12, 2020, we screened 277 septic patients and eventually enrolled 100 patients, with 50 assigned to the aminophylline group and 50 to the usual-care group. At 28 days, 7 of 50 patients (14.0%) in the aminophylline group had died, compared with 16 of 50 (32.0%) in the usual-care group (P = 0.032). Cox regression showed that the aminophylline group had a lower hazard of death (hazard ratio = 0.312, 95% confidence interval: 0.129–0.753). Compared with the usual-care group, patients in the aminophylline group had a longer survival time (P = 0.039 by the log-rank test). The effects of aminophylline on vasopressor dose, oxygenation index, and sequential organ failure assessment score were time-dependent with treatment. There were no significant differences in total hospitalization days, ICU hospitalization days, and rates of serious adverse events (all P > 0.05). No adverse events were observed in the trial. Conclusions:. Aminophylline as an adjunct therapy could significantly reduce the risk of death and prolong the survival time of patients with sepsis. Trial registration:.

Abstract Purpose Current knowledge of Lymphoma Associated Hemophagocytic Syndrome (LAHS) mainly relies on T/NK-cell LAHS cases, while B-cell lymphoma associated hemophagocytic syndrome (B-LAHS) variant are rare. We aimed at identifying a single-center cohort of patients with B-LAHS to shed light on relevant clinical and laboratory features, diagnosis, treatment and prognosis. Methods The clinical data of 36 patients with B-LAHS, admitted to the First Affiliated Hospital of Zhengzhou University in the time period ranging from January 2011 to May 2021 were analyzed retrospectively. Survival analysis was performed using the Kaplan–Meier method and groups were compared using the log-rank test. Results The 36 patients included 17 males and 19 females with a median age of 53.5 years (range: 28–74 years). Among these, the most common histopathological type diagnosed was diffuse large B-cell lymphoma (69%). The initial symptoms included fever (100%), splenomegaly (97%), multicavity effusion (83%), abnormal liver function (58%), and jaundice (44%). Patients treated with dexamethasone only seemed to have an inferior prognosis compared to those treated with etoposide-involving regimens (χ2 = 20.037, p < 0.001). Patients received based on the Hemophagocytic Lymphohistocytosis (HLH)-2004 protocol combined with multidrug chemotherapy had a significantly improved Overall Survival (OS) compared to patients who only underwent treatment according to the HLH-2004 regimen (χ2 = 30.744, p < 0.001). The 2-week mortality rate was 13.9% and the 1-year OS rate was 19.4%. Compared with the median survival time of 34 patients without Epstein-Barr virus (EBV) infection, 97 days (range: 24–322 days), two patients with EBV infection died within 8 days. Conclusion B-LAHS is relatively rare and has a high early mortality rate, mostly in middle-aged and elderly patients. The HLH-2004 regimen combined with multidrug chemotherapy is a reasonable choice for the treatment of B-LAHS, and EBV infection may be used as a reference indicator of a poor prognosis.

Abstract Background High morbidity and mortality due to carbapenem-resistant Gram-negative bacilli (CR-GNB) has led to the resurgence of polymyxin B (PMB) use in the last decade. The aim of our multicenter, real-world study was to evaluate the effectiveness and safety of PMB in the treatment of CR-GNB infections. Methods The real-world study included patients treated with intravenous PMB for at least 7 days during the period of October 2018 through June 2019. Associations between these clinical features and 28-day mortality or all-cause hospital mortality were explored through univariate analyses and multivariable logistic regression. Results The study included 100 patients. Many patients presented with combined chronic conditions, septic shock, mechanical ventilation, and the presence of Klebsiella pneumoniae. The mean duration of PMB therapy was 11 days (range 7–38 days). Temperature (38 °C vs 37.1 °C), white blood cells (14.13 × 109/l vs 9.28 × 109/l), C-reactive protein (103.55 ug/l vs 47.60 ug/l), procalcitonin (3.89 ng/ml vs 1.70 ng/ml) and APACHE II levels (17.75 ± 7.69 vs 15.98 ± 7.95) were significantly decreased after PMB treatment. The bacteria eradication rate was 77.65%. The overall mortality at discharge was 15%, and 28-day mortality was 40%. Major adverse reactions occurred in 16 patients. Nephrotoxicity was observed in 7 patients (7%). Conclusions Our results provide positive clinical and safety outcomes for PMB in the treatment of CR-GNB. Timely and appropriate use of PMB may be particularly useful in treating patients with sepsis in CR-GNB infections.
