This study evaluated the effects of inhaled nitric oxide (iNO) therapy combined with intravenous (IV) corticosteroids on hemodynamics, selected cytokines, and kidney messenger RNA toll-like receptor 4 (mRNA TLR4) expression in ischemia–reperfusion injury animal model. The primary endpoint was the evaluation of circulatory, respiratory, and renal function over time. We also investigated the profile of selected cytokines and high-mobility group box 1 (HMGB1) protein, as well as renal mRNA TLR4 activation determined by quantitative real-time polymerase chain reaction analysis. Pigs (n = 19) under sevoflurane AnaConDa anesthesia/sedation were randomized and subjected to abdominal laparotomy and alternatively suprarenal aortic cross-clamping (SRACC) for 90 min or sham surgery: Group 1 (n = 8) iNO (80 ppm) + IV corticosteroids (25 mg ×3) started 30 min before SRACC and continued 2 h after SRACC release, followed with decreased iNO (30 ppm) until the end of observation, Group 2 (n = 8) 90 min SRACC, Group 3 (n = 3)—sham surgery. Renal biopsies were sampled 1 hr before SRACC and at 3 and 20 h after SRACC release. Aortic clamping increased TLR4 mRNA expression in ischemic kidneys, but significant changes were recorded only in the control group ( P = 0.016). Treatment with iNO and hydrocortisone reduced TLR4 mRNA expression to pre-ischemic conditions, and the difference observed in mRNA expression was significant between control and treatment group after 3 h ( P = 0.042). Moreover, animals subjected to treatment with iNO and hydrocortisone displayed an attenuated systemic inflammatory response and lowered pulmonary vascular resistance plus increased oxygen delivery. The results indicated that iNO therapy combined with IV corticosteroids improved central and systemic hemodynamics, oxygen delivery, and diminished the systemic inflammatory response and renal mRNA TLR4 expression.

We have evaluated the effect of early and late micro-ecological enteral nutrition on systemic inflammatory response, bacterial translocation, and immune function in patients with severe acute pancreatitis. Two weeks after treatment, experimental group receiving early nutritional intervention exhibited a significant increase in intestinal lactobacilli and bifidobacteria, fewer staphylococci, and E. coli, and lower levels of serum endotoxin, D-lactic acid, and diamine oxidase than the group receiving late intervention (control group) (P < 0.05). Also, the serum levels of CD3+ and CD4+ and CD4+/CD8+ ratio significantly increase after 2 weeks of intervention. On the other hand, the level of CD8+ and the Acute Physiology and Chronic Health Evaluation II and Modified Computed Tomography Severity Index scores significantly decreased after 2 weeks of treatment (P < 0.05). The early intervention also led to a significant shortening of time needed for abdominal pain relief, anal exhaustion, resumption of peristaltic sound, and hospitalization. Furthermore, there was a significant increase in overall response rate, and decrease in the incidence rate of complications (P < 0.05). Early micro-ecological enteral nutrition therapy can effectively relieve systemic inflammatory response, prevent intestinal bacterial translocation, restore the function of intestinal mucosal barrier, and alleviate nutritional imbalance in severe acute pancreatitis patients leading to improved immune function, mitigation of the disease, and reduced complications benefiting the recovery of patients.

The early diagnosis of sepsis increases the chances of its successful treatment. Biomarkers are able to distinguish between systemic inflammatory response syndrome and sepsis and are used to monitor pro- and anti-inflammatory changes associated with the host response to pathogens. A total of 11 rats underwent sepsis induction and measured systolic, diastolic and mean arterial blood pressure. Leukocyte counts, procalcitonin, and nitric oxide also were measured 0, 2, and 4 hours after the induction of sepsis using the cecal ligation and puncture method. The animals were divided into two groups: control (SHAM) and induced. Procalcitonin levels remained within the normal range for an inflammatory response throughout the experiment. There was a statistically insignificant increase in nitric oxide levels. All animals showed increased diastolic arterial blood pressure; however, the increase in the induced animals was even more pronounced. Procalcitonin and nitric oxide levels can increase due to surgical manipulation, while arterial blood pressure was not a good predictor for the onset of sepsis during the time period studied here.
