OBJECTIVE:
To investigate the value of maximal rate of left ventricular pressure (dp/dtmax) in evaluating the changes of cardiac function before and after heart rate reduction in patients with sepsis-induced cardiomyopathy (SIC).
METHODS:
A single-center, prospective randomized controlled study was conducted. Adult patients with sepsis/septic shock admitted to the department of intensive care unit (ICU) of Tianjin Third Central Hospital from April 1, 2020 to February 28, 2022 were enrolled. Speckle tracking echocardiography (STE) and pulse indication continuous cardiac output (PiCCO) monitoring were performed immediately after the completion of the 1 h-Bundle therapy. The patients with heart rate over 100 beats/minutes were selected and randomly divided into esmolol group and regular treatment group, 55 cases in each group. All patients underwent STE and PiCCO monitoring at 6, 24 and 48 hours after admission in ICU and calculated acute physiology and chronic health evaluation II (APACHE II) and sequential organ failure assessment (SOFA). Primary outcome measure: change in dp/dtmax after reducing heart rate by esmolol. Secondary outcome measures: correlation between dp/dtmax and global longitudinal strain (GLS); changes of vasoactive drug dosage, oxygen delivery (DO2), oxygen consumption (VO2) and stroke volume (SV) after the administration of esmolol; proportion of heart rate reaching the target after the administration of esmolol; 28-day and 90-day mortality in two groups.
RESULTS:
Baseline data on age, gender, body mass index, SOFA score, APACHE II score, heart rate, mean arterial pressure, lactic acid, 24-hour fluid balance, sepsis etiology and prior comorbidities were similar between esmolol group and regular treatment group, there were no significant differences between the two groups. All SIC patients achieved the target heart rate after 24 hours of esmolol treatment. Compared with regular treatment group, parameters reflecting myocardial contraction such as GLS, global ejection fraction (GEF) and dp/dtmax were significantly increased in esmolol group [GLS: (-12.55±4.61)% vs. (-10.73±4.82)%, GEF: (27.33±4.62)% vs. (24.18±5.35)%, dp/dtmax (mmHg/s): 1 312.1±312.4 vs. 1 140.9±301.0, all P < 0.05], and N-terminal pro-brain natriuretic peptide (NT-proBNP) significantly decreased [μg/L: 1 364.52 (754.18, 2 389.17) vs. 3 508.85 (1 433.21, 6 988.12), P < 0.05], DO2 and SV were significantly increased [DO2 (mL×min-1×m-2): 647.69±100.89 vs. 610.31±78.56, SV (mL): 49.97±14.71 vs. 42.79±15.77, both P < 0.05]. The system vascular resistance index (SVRI) in esmolol group was significantly higher than that in regular treatment group (kPa×s×L-1: 287.71±66.32 vs. 251.17±78.21, P < 0.05), even when the dosage of norepinephrine was similar between the two groups. Pearson correlation analysis showed that dp/dtmax was negatively correlated with GLS in SIC patients at 24 hours and 48 hours after ICU admission (r values were -0.916 and -0.935, respectively, both P < 0.05). Although there was no significant difference in 28-day mortality between esmolol group and regular treatment group [30.9% (17/55) vs. 49.1% (27/55), χ2 = 3.788, P = 0.052], the rate of esmolol use in patients who died within 28 days was lower than that in patients who survived [38.6% (17/44) vs. 57.6% (38/66), χ2 = 3.788, P = 0.040]. In addition, esmolol has no effect on the 90-day mortality of patients. Logistic regression analysis showed that after adjusting for SOFA score and DO2 factors, patients who used esmolol had a significantly lower risk of 28-day mortality compared with patients who did not use esmolol [odds ratio (OR) = 2.700, 95% confidence interval (95%CI) was 1.038-7.023, P = 0.042].
CONCLUSIONS
dp/dtmax in PiCCO parameter can be used as a bedside indicator to evaluate cardiac function in SIC patients due to its simplicity and ease of operation. Esmolol control of heart rate in SIC patients can improve cardiac function and reduce short-term mortality.

Maternal septic shock and disseminated intravascular coagulation (DIC) following amniocentesis is a relatively rare condition, and its incidence is only 0.03~0.19%. Acute myocardial infarction (AMI) associated with DIC is also rare. We report here on a 40-year-old female patient who had septic shock and DIC that was complicated by AMI following amniocentesis. The possible mechanism of AMI in this patient may have been coronary artery thrombosis associated with DIC.

We describe a case of septic shock due to Vibrio alginolyticus presenting with fever and bilateral leg pain. Despite intensive management with antibiotics and inotropic agents, the patient died from septic shock 1 day after hospitalization. V. alginolyticus was isolated from both leg wounds and a blood culture. To the best of our knowledge, this is the first reported case of V. alginolyticus bacteremia in Korea.

9.Necrotizing fasciitis following varicella in a child.
Chinese Medical Journal 2012;125(5):951-953
Varicella is a self-limited disease, but sometimes it may be associated with some serious life-threatening complications.Necrotizing fasciitis is a rare complication of varicella. This is a case of a 7-year-old girl with septic shock caused by necrotizing fasciitis as a complication of varicella. Swelling and pain in the left inguinal region and left axillary region were found five days after varicella. Then a high fever occurred followed by hypotension. Fluid infusion, vasopressor and antibiotics were administered. Group A beta-hemolytic Streptococcus was isolated from exudates from the wounds. The clinical symptoms markedly improved after surgical drainage and removal of the necrotic tissue. Both wounds were covered with skin grafts after healthy granulation tissue formed. Although there have been few reports of life-threatening necrotizing fasciitis following varicella in western countries, it is rare in China. Usually patients with varicella were admitted to pediatric or infectious disease department but not surgical departments; so that the clinicians should be aware that varicella may be complicated by life-threatening surgical infections. Necrotizing fasciitis should be suspected in patients of varicella who showed an increasing pain and swelling in any body areas associated with increasing fever and local erythema. Early identification, surgical drainage and debridement are essential for successful treatment of necrotizing fasciitis.

10.Significance of gaseous signal molecule in the pathogenesis of cardiovascular diseases.

The discovery of nitric oxide (NO) initiated a novel research field, gaseous signal molecules. Other two gaseous signal molecules, carbon monoxide (CO) and hydrogen sulfide (H2S), have been approved subsequently. All of these three gaseous signal molecules are generated endogenously and exert extensive biological effects. This article reviews the significance of gaseous signal molecules in the pathogenesis of cardiovascular diseases. In the cardiovascular system, the endogenous NO, CO and H2S form three specific and relevant pathways with their corresponding enzymes including nitric oxide synthase (NOS), heme oxygenase (HO), and cystathionine-gamma-lyase (CSE). The gaseous signal molecules not only participate in the maintenance of physiological function and structure of the cardiovascular system, but also exert important pathophysiological effects in the pathogenesis of cardiovascular diseases, such as hypertension, pulmonary hypertension, septic shock and atherosclerosis. Further studies on gaseous signal molecules will remarkably promote the basic research in the cardiovascular fields, and provide a novel direction for the clinical research as well.
