Burn Resuscitation

Resuscitation of adult patients with burn size greater than 20% total body surface area (TBSA) and pediatric patients with burn size greater than 15% TBSA is essential for early survival due to the fluid shifts that occur after injury. After the primary and secondary survey, burn resuscitation is different from resuscitation from other types of shock because it is based on continuous fluid administration. Judicious use of fluids reduces fluid creep and complications of over-resuscitation. Accurate estimation of TBSA will improve the use of crystalloids. Furthermore, inhalation injury, chemical injury, electrical injury, and preexisting comorbidities can complicate resuscitation of these patients. Although crystalloids are the mainstay of therapy, adjuncts to resuscitation such as colloids, plasma exchange, and high-dose vitamin C have been considered to reduce complications of over-resuscitation or support patients who are refractory to typical resuscitation strategies in the initial period post injury. Wound care should never precede the primary and secondary survey and most often can wait until definitive care at a burn center.

Abstract Introduction Estimates on frequency and outcomes of burn or inhalation injury in the United States are limited since reported databases are confined to specific phases of care, included facilities, length of follow-up, facility/provider/patient identification and/or lack of longitudinal tracking. A population-based database addresses these issues. Methods We queried a statewide mandated-reporting database for the years from 2000 through 2015 at the time of injury using a set of ICD9-CM codes for second degree or deeper burns, inhalation injury, and chemical and electrical burns. Burn total body surface area percentage by anatomical region was assigned as appropriate using modified and age-stratified Lund and Browder charts. Records for each patient were extracted out to one year pre- and post-injury, as available. Provider and facility burn volume and survival was stratified into quartiles. We applied the Committee on Trauma/American Burn Association referral criteria to the index presentation. Kaplan-Meier curves were generated to 1-year post injury for testing combinations of burn percent total body surface area of 20% and inhalation injury for age ranges < 15, 15 - 60, and >60 years. Regression models were developed to model the probabilities of in-patient, 90-day, and 365-day mortality and readmission. Results 56,712 patients were included. Overall, 22% of patients meeting referral criteria were never seen at a burn center within 1-year post-injury. The greatest positive predictors of in-patient mortality were facility case volume and burn percent total body surface area. The greatest negative predictors were high provider burn case volume (for highest quartile, adjusted odds ratio 0.08, 95% confidence intervals 0.06 – 0.12). The highest risk of unscheduled 30-day readmission was associated with index presentation to a non-burn care facility (p < 0.001). For all groups, the first 100 days had the greatest mortality rate, the most severe being among patients of age greater than 60 with >20% burn percent total body surface area and inhalation injury, with a 40% survival rate. Conclusions This study is the first to be able to simultaneously evaluate in-patient, post-discharge, and facility-based parameters for outcomes. A significant number of patients are not accounted with current databases. Applicability of Research to Practice A population-based approach with longitudinal tracking allows for greater realization of the outcomes of all patients following burn injury. Existing association-supported or government databases fail to account for a significant portion of burn victims, motivating further evaluation of burn care efforts.

Abstract Introduction Controversy exists over the use of colloid required for burn resuscitation. Data show that fresh frozen plasma (FFP) may have benefits beyond volume sparing alone, however, there are inherent risks including transfusion related acute lung injury (TRALI) and transfusion reactions (TR). The aims of this project were: (1) determine the effectiveness of early FFP during burn resuscitation, and (2) to document any potential side effects of FFP administration. Methods A retrospective review was performed on all burn patients aged >18 years old with >20% total body surface area (TBSA) burns who underwent resuscitation using our nursing guided resuscitation protocol (NGRP) from November 2016- June 2019 at our ABA- verified burn center. Excluded were those with electrical injury, delayed resuscitation, polytrauma, renal replacement therapy and or death within 24 hours (hrs) of injury. Pursuant to the NGRP all patients with >30% TBSA burns received FFP at 6–8 hrs post injury. Data recorded included: demographics, % TBSA burned, total crystalloid/FFP, and urine output (UO). An hourly resuscitation ratio (I/O ratio) of fluid given (ml/kg/%TBSA/hr) to UO (ml/kg/hr) was calculated. FFP initiation was standardized to time zero. Major complications such as abdominal compartment syndrome (ACS), acute respiratory distress syndrome (ARDS), TRALI and TR were documented. Univariate statistical analysis was performed. Results Over the study period 71 patients required NGRP resuscitation, 56 met inclusion criteria. Baseline demographics included: 47 male (84%), median age 34 years [IQR 27–53], median TBSA 30% [range 20–95%]. 40 patients were resuscitated with FFP versus 16 patients resuscitated with crystalloid alone. Median time to FFP administration was 7 hours [IQR 6–8] with an average of 1866 ml infused [779–4484]. Those who received FFP had larger % TBSA burns median 41% [29–57] vs no FFP 22% [20–24], p< 0.001. Median I/O ratio at FFP initiation improved from 1.0 [IQR 0.4–3.7] to 0.4 [IQR 0.2–1.5, p=0.01] at 2 hrs post FFP, see Graph. Median UOP improved from 0.18 cc/kg/hr the 2 hrs prior to FFP administration, to 0.44 cc/kg/hr at 2 hrs post FFP (p=0.01). Total 24 hour fluids given (cc/kg/% TBSA) were similar in both groups: FFP 3.94 [3.49–5.36] vs no FFP 3.92 [3.54–4.53], p=0.77. There were no reported incidents of ACS, ARDS, TRALI, or TR. Conclusions The use of FFP in burn resuscitation significantly improves UOP and normalizes I/O ratios. FFP administration did not cause any serious complications. Applicability of Research to Practice Future research efforts should focus on comparing albumin vs FFP in acute burn resuscitation.

Burn Resuscitation

Abstract On June 17-18, 2019, the American Burn Association, in conjunction with Underwriters Laboratories, convened a group of experts on burn and inhalation injury in Washington, DC. The goal of the meeting was to identify and discuss strategies to optimize the process of burn resuscitation. Patients who sustain a large thermal injury (involving >20% of the total body surface area [TBSA]) face a sequence of challenges, beginning with burn shock. Over the last century, research has helped elucidate much of the underlying pathophysiology of burn shock, which places multiple organ systems at risk of damage or dysfunction. These studies advanced the understanding of the optimal use of fluids for resuscitation. The resultant practice of judicious and timely infusion of crystalloids has likely improved mortality after major thermal injury. However, much remains unclear about how to further improve and customize resuscitation practice to limit the morbidities associated with edema and volume overload. Herein, we review the history and pathophysiology of shock following thermal injury, and propose some of the priorities for resuscitation research. Recommendations include: studying the utility of alternative endpoints to resuscitation, re-examining plasma as a primary or adjunctive resuscitation fluid, and applying information about inflammation and endotheliopathy to target the underlying causes of burn shock. Undoubtedly, these future research efforts will require a concerted effort from the burn and research communities.

Cellular Rejection

: Although acute renal graft rejection rate has declined in the last years, and because an adequate therapy can improve graft outcome, its therapy remains as one of the most significant challenges for pharmacists and physicians taking care of transplant patients. Due to the lack of evidence highlighted by the available metaanalyses, we performed a narrative review focused on the basic mechanisms and current and future therapies of acute rejection in kidney transplantation. : According to Kidney Disease/Improving Global Outcomes (KDIGO) guidelines, both clinical and subclinical acute rejection episodes should be treated. Usually, high dose steroids and basal immunosuppression optimization are the first line of therapy in treating acute cellular rejection. Rabbit antithymocytic polyclonal globulins are used as rescue therapy for recurrent or steroid-resistant cellular rejection episodes. Current standard-of-care (SOC) therapy for acute antibody-mediated rejection (AbMR) is the combination of plasma exchange with intravenous immunoglobulin (IVIG). Since a significant rate of AbMR does not respond to SOC, different studies have analyzed the role of new drugs such as Rituximab, Bortezomib, Eculizumab and C1 inhibitors. Lack of randomized controlled trials and heterogenicity among performed studies limit obtaining definite conclusions. Data about new direct and indirect B cell and plasma cell depleting agents, proximal and terminal complement blockers, IL-6/IL-6R pathway inhibitors and antibody removal agents, among other promising drugs, are reviewed.

Abstract Introduction In burn patients, vitamin D deficiency has been associated with increased incidence of sepsis. The objective of this study was to assess the impact of vitamin D deficiency in adult burn patients on hospital length of stay (LOS). Methods This was a multi-center retrospective study of adult patients at 7 burn centers admitted between January 1, 2016 and July 25, 2019 who had a 25-hydroxyvitamin D (25OHD) concentration drawn within the first 7 days of injury. Patients were excluded if admitted for a non-burn injury, total body surface area (TBSA) burn less than 5%, pregnant, incarcerated, or made comfort care or expired within 48 hours of admission. The primary endpoint was to compare hospital LOS between burn patients with vitamin D deficiency (defined as 25OHD < 20 ng/mL) and sufficiency (25OHD ≥ 20 ng/mL). Secondary endpoints include in-hospital mortality, ventilator-free days of the first 28, renal replacement therapy (RRT), length of ICU stay, and days requiring vasopressors. Additional data collected included demographics, Charlson Comorbidity Index, injury characteristics, form of vitamin D received (ergocalciferol or cholecalciferol) and dosing during admission, timing of vitamin D initiation, and form of nutrition provided. Dichotomous variables were compared via Chi-square test. Continuous data were compared via student t-test or Mann-Whitney U test. Univariable linear regression was utilized to identify variables associated with LOS (p < 0.05) to analyze further. Cox Proportional Hazard Model was utilized to analyze association with LOS, while censoring for death, and controlling for TBSA, age, presence of inhalation injury, and potential for a center effect. Results Of 1,147 patients screened, 412 were included. Fifty-seven percent were vitamin D deficient. Patients with vitamin D deficiency had longer LOS (18.0 vs 12.0 days, p < 0.001), acute kidney injury (AKI) requiring RRT (7.3 vs 1.7%, p = 0.009), more days requiring vasopressors (mean 1.24 vs 0.58 days, p = 0.008), and fewer ventilator free days of the first 28 days (mean 22.9 vs 25.1, p < 0.001). Univariable analysis identified burn center, AKI, TBSA, inhalation injury, admission concentration, days until concentration drawn, days until initiating supplementation, and dose as significantly associated with LOS. After controlling for center, TBSA, age, and inhalation injury, the best fit model included only deficiency and days until vitamin D initiation. Conclusions Patients with thermal injuries and vitamin D deficiency on admission have increased length of stay and worsened clinical outcomes as compared to patients with sufficient vitamin D concentrations.

Abstract Background Immune checkpoint inhibitors (ICIs) can cause cardiac immune-related adverse events (irAEs), including pericarditis. Cardiovascular events related to pericardial irAE are less frequent, but fulminant forms can be fatal. However, the diagnosis and treatment strategies for pericardial irAE have not established. Case summary A 58-year-old man was diagnosed with advanced non-small-cell lung cancer and nivolumab was administered as 5th-line therapy. Eighteen months after the initiation of nivolumab, the patient developed limb oedema and increased body weight. Although a favourable response of the cancer was observed, pericardial thickening and effusion were newly detected. He was diagnosed with irAE pericarditis after excluding other causes of pericarditis. Nivolumab was suspended and a high-dose corticosteroid was initiated. However, right heart failure (RHF) symptoms were exacerbated during the tapering of corticosteroid because acute pericarditis developed to steroid-refractory constrictive pericarditis. To suppress sustained inflammation of the pericardium, infliximab, a tumour necrosis factor-alfa inhibitor, was initiated. After the initiation of infliximab, the corticosteroid dose was tapered without deterioration of RHF. Exacerbation of lung cancer by irAE treatment including infliximab was not observed. Discussion IrAE should be considered when pericarditis develops after the administration of ICI even after a long period from its initiation. Infliximab rescue therapy may be considered as a 2nd-line therapy for steroid-refractory irAE pericarditis even with constrictive physiology.

A 26-year-old, 17-week pregnant woman developed aquaporin-4-IgG-positive severe longitudinally extensive transverse myelitis during the course of disseminated herpes zoster and became quadriparetic. She was unresponsive to high-dose intravenous methylprednisolone but became able to walk without assistance after intravenous immunoglobulin. One and a half months later, left optic neuritis developed but her vision improved with intravenous immunoglobulin. The only sequela was left T5 girdle sensation, and she delivered a healthy baby. Intravenous immunoglobulin may be a rescue therapy in aquaporin-4-IgG-positive neuromyelitis optica attacks in pregnant women, especially those with severe infections.

Abstract Introduction Adipose stem cells (ASCs) have shown therapeutic promise for inflammatory conditions that beget multi organ dysfunction, including burns. While ASCs have immunomodulatory properties, some studies have brought up safety concerns of increased pro-coagulant activity such as pulmonary microvascular thrombi formation after intravenous (IV) administration of ASCs. In the present study, the aims are two-fold: 1) to verify if IV administration of human ASCs promotes coagulation and 2) to determine if human ASCs affect organ function in a 40% total body surface area (TBSA) swine burn model. Methods Female Yorkshire swine (39.63 ± 8.26kg) were anesthetized and subjected to 40% TBSA full thickness contact burns according to a formerly established model. After recovery from anesthesia, animals were randomized to receive 15ml/kg Lactated Ringer’s Solution containing: 1- no ASCs; 2- a low dose (5x105 ASCs/kg), or 3- a high dose (5x106 ASCs/kg) over a 15-minute period as a bolus. Blood was collected at baseline (BL) and 3, 6, 12, and 24h post burn to determine the effect of ASCs on organ function and coagulation status. At 24h post-burn, animals were humanely euthanized, and kidney and liver tissue was collected for histological and Western blot analyses. Data is presented as mean ± SEM, and statistical significance was set at p< 0.05. Results The high dose of ASCs significantly increased the circulating number of monocytes starting at 12 hours. Two-way ANOVA revealed a significant effect of ASCs on both prothrombin times (PT) and international normalized ratio (INR) (1.03 ± 0.04, 0.93 ± 0.03, and 1.02 ± 0.04 for no, low and high ASC groups, respectively at 24 hours). There were no differences in partial thromboplastin time, fibrinogen, or d-dimer levels. Both doses of ASCs briefly exacerbated burn-induced increases in total bilirubin at 3 hours (0.062 ± 0.025mg/dL, 0.148 ± 0.060mg/dL, and 0.211 ± 0.086mg/dL in no, low, and high ASC groups, respectively). ASCs did not alter urine output; yet, there was a significant effect of ASCs on creatinine. Western blotting revealed a rise in caspase expression in the liver of animals receiving a low dose of ASCs, while there was no difference in caspase expression in kidneys. Conclusions We show that IV administration of xenogeneic ASCs produces minimal changes in coagulation status and renal and hepatic dysfunction. Modest changes in the extrinsic coagulation pathway were dose-dependent, while exacerbation of liver dysfunction was brief and normalized after administration of ASCs was completed. We cannot rule out that continuous infusion of ASCs would not have a cumulative effect on organ dysfunction.
