Epidemiology of Diffuse Alveolar Hemorrhage in Pediatric Allogeneic Hematopoietic Cell Transplant Recipients. Transplant Cell Ther 2024:S2666-6367(24)00553-0. [PMID: 39089527 DOI: 10.1016/j.jtct.2024.07.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Revised: 07/15/2024] [Accepted: 07/27/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND Diffuse alveolar hemorrhage (DAH) is a life-threatening pulmonary toxicity that can arise after hematopoietic cell transplantation (HCT). Risk-factors and outcomes are not well-understood due to a sparsity of cases spread across multiple centers. OBJECTIVES The objectives of this epidemiologic study were to characterize the incidence, outcomes, transplant-related risk factors and co-morbid critical care diagnoses associated with post-HCT DAH. STUDY DESIGN Retrospective analysis was performed on a multi-center cohort of 6,995 patients ≤21 years old who underwent allogeneic HCT between 2008-2014 identified through the Center for International Blood and Marrow Transplant Research registry and cross-matched with the Virtual Pediatric Systems database to obtain critical care characteristics. A multivariable Cox-proportional hazard model was used to determine risk factors for DAH. Logistic regression models were used to determine critical care diagnoses associated with DAH. Survival outcomes were analyzed using both a landmark approach and Cox-regression with DAH as a time-varying covariate. RESULTS DAH occurred in 81 patients at a median 54 days post-HCT (IQR 23-160 days), with a 1-year post-transplant cumulative incidence probability of 1.0% (95% CI 0.81-1.3%) and was noted in 7.6% of all PICU patients. Risk factors included transplant for non-malignant hematologic disease (Referent: malignant hematologic disease, HR=1.98, 95% CI 1.22-3.22, p=0.006), use of calcineurin inhibitor plus mycophenolate mofetil (CNI + MMF) as GvHD prophylaxis, (Referent: calcineurin inhibitor plus methotrexate, HR=1.89, 95% CI 1.07-3.34, p=0.029), and grade III-IV acute GvHD (HR=2.67, 95% CI 1.53-4.66, p<0.001). Critical care admitted patients with DAH had significantly higher rates of systemic hypertension, pulmonary hypertension, pericardial disease, renal failure, and bacterial/viral/fungal infections (p<0.05) than those without DAH. From the time of DAH, median survival was 2.2 months and one-year overall survival was 26% (95% CI 17-36%). Among all HCT patients, the development of DAH when considered was associated with a seven-fold increase in unadjusted all-cause post-HCT mortality (HR 6.96, 95% CI 5.42-8.94, p<0.001). In a landmark analysis of patients alive 2 months post-HCT, patients who developed DAH had a one-year overall survival of 33% (95% CI 18-49%) versus 82% (95% CI 81-83%) for patients without DAH (p<0.001). CONCLUSION Although DAH is rare, it is associated with high mortality in the post-HCT setting. Our data suggest that clinicians should have a heightened index of suspicion of DAH in patients with pulmonary symptoms in the context of non-malignant hematologic transplant indication, use of CNI + MMF as GvHD prophylaxis and severe acute GvHD. Further investigations and validation of modifiable risk factors are warranted given poor outcomes.

Abstract
OBJECTIVES To derive systematic-review informed, modified Delphi consensus regarding antifibrinolytic and adjunct hemostatic agents in neonates and children supported with extracorporeal membrane oxygenation (ECMO) for the Pediatric ECMO Anticoagulation CollaborativE consensus conference. DATA SOURCES A structured literature search was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021. STUDY SELECTION Use of antifibrinolytics (epsilon-aminocaproic acid [EACA] or tranexamic acid), recombinant factor VII activated (rFVIIa), or topical hemostatic agents (THAs). DATA EXTRACTION Two authors reviewed all citations independently, with a third independent reviewer resolving conflicts. Eleven references were used for data extraction and informed recommendations. Evidence tables were constructed using a standardized data extraction form. MEASUREMENTS AND MAIN RESULTS Risk of bias was assessed using the Quality in Prognosis Studies tool. The evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation system. Forty-eight experts met over 2 years to develop evidence-based recommendations and, when evidence was lacking, expert-based consensus statements for the management of bleeding and thrombotic complications in pediatric ECMO patients. A web-based modified Delphi process was used to build consensus via the Research And Development/University of California Appropriateness Method. Consensus was defined as greater than 80% agreement. One weak recommendation and three consensus statements are presented. CONCLUSIONS Evidence supporting recommendations for administration of antifibrinolytics (EACA or tranexamic acid), rFVIIa, and THAs were sparse and inconclusive. Much work remains to determine effective and safe usage strategies.

Abstract
Massive hemoptysis is a time critical airway emergency in the perioperative setting, with an associated mortality exceeding 50%. Causes of hemoptysis in the perioperative setting include procedural complication, coagulopathy, malignancy, chronic lung disease, infection, left-sided cardiac disease, pulmonary vascular disease and autoimmune disease. A rapid and coordinated multidisciplinary response is required to secure the airway, isolate the lung, ensure adequate oxygenation and ventilation, identify the underlying cause and initiate specific systemic, bronchoscopic, endovascular, or surgical treatment. This review examines the etiology, pathophysiology, as well as approach to management and interventions in perioperative massive hemoptysis.

Abstract
Introduction Diffuse alveolar hemorrhage (DAH) is a devastating disease process with 50-100% mortality in oncology and hematopoietic cell transplant (HCT) recipients. High concentrations of tissue factors have been demonstrated in the alveolar wall in acute respiratory distress syndrome and DAH, along with elevated levels of tissue factor pathway inhibitors. Activated recombinant factor VII (rFVIIa) activates the tissue factor pathway, successfully overcoming the tissue factor pathway inhibitor (TFPI) inhibition of activation of Factor X. Intrapulmonary administration (IP) of rFVIIa in DAH is described in small case series with successful hemostasis and minimal complications. Methods We completed a single center retrospective descriptive study of treatment with rFVIIa and outcomes in pediatric oncology and HCT patients with pulmonary hemorrhage at a quaternary hematology/oncology hospital between 2011 and 2019. We aimed to assess the safety and survival of patients with pulmonary hemorrhage who received of IP rFVIIa. Results We identified 31 patients with pulmonary hemorrhage requiring ICU care. Thirteen patients received intrapulmonary rFVIIa, while eighteen patients did not. Overall, 13 of 31 patients (41.9%) survived ICU discharge. ICU survival (n=6) amongst those in the IP rFVIIa group was 46.2% compared to 38.9% (n=7) in those who did not receive IP therapy (p=0.69). Hospital survival was 46.2% in the IP group and 27.8% in the non-IP group (p=0.45). There were no adverse events noted from use of IP FVIIa. Conclusions Intrapulmonary rFVIIa can be safely administered in pediatric oncology patients with pulmonary hemorrhage and should be considered a viable treatment option for these patients.

Abstract
PURPOSE This article summarizes emerging nontraditional therapies administered via the nebulization route for use in the emergency department (ED). SUMMARY Although traditional routes of medication administration (eg, intravenous) have been the mainstay of administration modalities for decades, these routes may not be appropriate for all patients. Nowhere is this more readily apparent than in the ED setting, where patients with a variety of presentations receive care. One unique route for medication administration that has increasingly gained popularity in the ED is that of aerosolized drug delivery. This route holds promise as direct delivery of medications to the site of action could yield a more rapid and effective therapeutic response while also minimizing systemic adverse effects by utilizing a fraction of the systemic dose. Medication administration via nebulization also provides an alternative that is conducive to rapid, less invasive access, which is advantageous in the emergent setting of the ED. This review is intended to analyze the existing literature regarding this route of administration, including the nuances that can impact drug efficacy, as well as the available literature regarding novel, noncommercial nebulized medication therapy given in the ED. CONCLUSION Multiple medications have been investigated for administration via this route, and when implementing any of these therapies several practical considerations must be taken into account, from medication preparation to administration, to ensure optimal efficacy while minimizing adverse effects. The pharmacist is an essential bedside team member in these scenarios to assist with navigating unique and complex nuances of this therapy as they develop.

Abstract
RATIONALE Different populations have their own unique physiological and pathological characteristics. However, in specialized maternal and child hospitals, there is currently a lack of standardized methods for assessing coagulation dysfunction, both domestically and internationally. PATIENT CONCERNS A 19-day-old neonate was transferred to neonatal intensive care unit with cyanosis, nasal bleeding for 6 hours, and a consciousness disorder for 5 hours. A 33-year-old woman presented with hydramnios and a 39 + 3week intrauterine pregnancy. All indicators before delivery were normal, but postpartum hemorrhage occurred after delivery. DIAGNOSES We retrospectively analyzed 1 neonate with pulmonary hemorrhage accompanied by thrombocytopenia and 1 pregnant patient with amniotic fluid embolism. INTERVENTIONS The new coagulation indicators, such as thrombin-antithrombin complex, plasmin-alpha 2 antiplasmin complex, thrombomodulin, and tissue plasminogen activator-plasminogen activator inhibitor-1 complex, have been indicated to be valuable. In neonates, it is necessary to continuously monitor special items combined with specific therapeutic agents, such as tranexamic acid. In cases where postpartum hemorrhage occurs with low fibrinogen levels, it is essential to effectively identify patients with severe amniotic fluid embolism from a high incidence of specimen clotting. OUTCOMES The neonate's oxygen saturation stabilized, and after 5 days of treatment with low molecular weight heparin, thrombin-antithrombin complex and plasmin-alpha 2 antiplasmin complex returned to normal levels. The pregnant began to remove the remaining thrombus, the patient's condition recovered, and she had a good prognosis. LESSONS For pregnant and neonatal critical illnesses, it is necessary to develop personalized coagulation monitoring programs that provide realistic and reasonable treatment recommendations. Such programs should consider the unique physiological and pathological characteristics of different populations to ensure effective management of critically ill patients.

Abstract
Diffuse alveolar hemorrhage (DAH) is a morbid syndrome that occurs after autologous and allogeneic hematopoietic cell transplantation in children and adults. DAH manifests most often in the first few weeks following transplantation. It presents with pneumonia-like symptoms and acute respiratory failure, often requiring high levels of oxygen supplementation or mechanical ventilatory support. Hemoptysis is variably present. Chest radiographs typically feature widespread alveolar filling, sometimes with peripheral sparing and pleural effusions. The diagnosis is suspected when serial bronchoalveolar lavages return increasingly bloody fluid. DAH is differentiated from infectious causes of alveolar hemorrhage when extensive microbiological testing reveals no pulmonary pathogens. The cause is poorly understood, though preclinical and clinical studies implicate pretransplant conditioning regimens, particularly those using high doses of total-body-irradiation, acute graft-versus-host disease (GVHD), medications used to prevent GVHD, and other factors. Treatment consists of supportive care, systemic corticosteroids, platelet transfusions, and sometimes includes antifibrinolytic drugs and topical procoagulant factors. Therapeutic blockade of tumor necrosis factor-α showed promise in observational studies, but its benefit for DAH remains uncertain after small clinical trials. Even with these treatments, mortality from progression and relapse is high. Future investigational therapies could target the vascular endothelial cell biology theorized to contribute to alveolar bleeding and pathways that contribute to susceptibility, inflammation, cellular resilience, and tissue repair. This review will help clinicians navigate through the limited evidence to diagnose and treat DAH, counsel patients and families, and plan for future research.

Abstract
Diffuse alveolar hemorrhage (DAH) is a life-threatening complication of hematopoietic cellular therapy (HCT). This study aimed to evaluate the effect of DAH treatments on outcomes using data from consecutive HCT patients clinically diagnosed with DAH from 3 institutions between January 2018-August 2022. Endpoints included sustained complete response (sCR) defined as bleeding cessation without recurrent bleeding, and non-relapse mortality (NRM). Forty children developed DAH at a median of 56.5 days post-HCT (range 1-760). Thirty-five (88%) had at least one concurrent endothelial disorder, including transplant-associated thrombotic microangiopathy (n=30), sinusoidal obstructive syndrome (n=19), or acute graft versus host disease (n=10). Fifty percent had a concurrent pulmonary infection at the time of DAH. Common treatments included steroids (n=17, 25% sCR), inhaled tranexamic acid (INH TXA,n=26, 48% sCR), and inhaled recombinant activated factor VII (INH fVIIa, n=10, 73% sCR). NRM was 56% 100 days after first pulmonary bleed and 70% at 1 year. Steroid treatment was associated with increased risk of NRM (HR 2.25 95% CI 1.07-4.71, p=0.03), while treatment with INH TXA (HR 0.43, 95% CI 0.19- 0.96, p=0.04) and INH fVIIa (HR 0.22, 95% CI 0.07-0.62, p=0.005) were associated with decreased risk of NRM. Prospective studies are warranted to validate these findings.

Nebulized vs IV Tranexamic Acid for Hemoptysis: A Pilot Randomized Controlled Trial. Chest 2023; 163:1176-1184. [PMID: 36410494 DOI: 10.1016/j.chest.2022.11.021] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 11/10/2022] [Accepted: 11/12/2022] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Tranexamic acid (TA) is used to control bleeding in patients with hemoptysis. However, the effectiveness of the different routes of TA administration has not been studied. RESEARCH QUESTION Does the nebulized route of TA administration reduce the amount of hemoptysis compared with the IV route in patients presenting to the ED with hemoptysis? STUDY DESIGN AND METHODS This was a pragmatic, open-label, randomized, parallel, single-center, pilot trial of nebulized TA (500 mg tid) vs IV TA (500 mg tid) in adult patients presenting to the ED with active hemoptysis. The primary outcome was cessation of bleeding at 30 min. Secondary outcomes included amount of hemoptysis at 6, 12, and 24 h; interventional procedures; and side effects of TA. Patients who were hemodynamically unstable or requiring immediate interventional procedure or mechanical ventilation were excluded from the study. RESULTS Of the 55 patients in each arm, hemoptysis cessation at 30 min following TA administration was significantly higher in the nebulization arm (n = 40) compared with the IV arm (n = 28): χ2 (1, n = 110) = 5.55; P = .0019. Also, hemoptysis amount was reduced significantly in the nebulization arm at all time periods of observation (P value at 30 min = .011, at 6 h = .002, 12 h = .0008, and at 24 h = .005). Fewer patients in the nebulization arm required bronchial artery embolization (13 vs 21; P = .024) and thereby had higher discharge rates from the ED (67.92% vs 39.02%; P = .005). Two patients in the nebulization arm had asymptomatic bronchoconstriction that resolved after short-acting beta-agonist nebulization. No patient discharged from the ED underwent any interventional procedure or revisited the ED with rebleed during the 72 h follow-up period. INTERPRETATION Nebulized TA may be more efficacious than IV TA in reducing the amount of hemoptysis and need for ED interventional procedures. Future larger studies are needed to further explore the potential of nebulized TA compared with IV TA in patients with mild hemoptysis.

Abstract
Cardiac implantable electronic devices are being increasingly used for a variety of cardiovascular diseases. We describe a rare case of massive hemoptysis after device implantation. The patient was managed conservatively with reversal of anticoagulation and inhaled tranexamic acid and had a successful recovery. A systematic review accompanies the case presentation. The modality and difficulty of access appear to play a significant role in precipitating bleeding, believed to be the result of direct injury to the pulmonary parenchyma and vasculature. The condition is often self-limiting; however, anticoagulation reversal, intubation, endobronchial intervention, and transarterial embolization may be indicated in more severe pulmonary hemorrhage.

Abstract
Massive hemoptysis is a rare life-threatening condition in children. Individuals with non-cystic fibrosis bronchiectasis may present with various degrees of hemoptysis. Therapeutic measures are mainly derived from studies involving adults or various case reports of children with cystic fibrosis. The standard management of massive hemoptysis is limited to invasive bronchoscopy, bronchial artery embolization, and surgical resection. Tranexamic acid (TXA) use is limited to non-massive hemoptysis or as an adjuvant and temporizing measure before definitive treatment. We report the potential use of TXA as an emergency treatment for massive hemoptysis in a 10-year-old boy with non-cystic fibrosis bronchiectasis and chronic infection. The use of systemic TXA (250 mg every eight hours for five days) successfully stopped active bleeding beginning from the first dose and altered the need for invasive interventions. Although he experienced another episode of massive hemoptysis because of pneumonia and pulmonary exacerbation, invasive measures were not required because he responded to systemic TXA immediately. Moreover, no further recurrence of hemoptysis was noted on cessation of TXA and throughout two years of regular follow-up. Therefore, TXA could be considered a non-invasive therapy for children with massive hemoptysis, especially in the absence of standard invasive therapies.

Abstract
Diffuse alveolar haemorrhage (DAH) is a rare complication of antiphospholipid syndrome. With a mortality rate of 46%, early diagnosis and management remain an ongoing challenge. Case reports are limited, and management guidelines are not yet definitive. In this case report, we present a 43‐year‐old male with DAH who required high‐dose oral steroids, intravenous methylprednisolone cyclophosphamide and rituximab over 18 months to control life‐threatening episodes of pulmonary bleeding.

Abstract
Tranexamic acid (TXA) is widely utilized to control perioperative bleeding. TXA is considered a safe drug with few serious adverse effects, but many studies report TXA-associated seizures especially with cardiac surgeries. Usually, TXA-associated seizures persist for few minutes with no progression into status epilepticus. Here, we report, for the first time, a case of refractory status epilepticus after IV injection of TXA in a pediatric non-cardiac surgery. This case report and literature review aim to increase awareness about TXA-associated seizures and to provide mechanistic-based prevention and treatment recommendations. During adenotonsillectomy for a 4-year-old male child, TXA infusion started after induction of anesthesia for surgical bleeding prophylaxis. During recovery from anesthesia, the patient developed tonic-clonic convulsions which did not improve after two IV doses of midazolam but showed an improvement after a dose of propofol. The patients did not regain consciousness and was transferred to the ICU. He had recurrent treatment-resistant attacks of tonic-clonic convulsions. The patient developed acute kidney injury and died after 18 hours. In high-risk patients, using the lowest effective dose with early termination of TXA infusion and prolongation of administration of anesthetics may prevent seizures. General anesthetics (propofol and halogenated inhaled anesthetics) are considered the first line for prevention/treatment of TXA-associated seizures.

Abstract
Noninfectious lung diseases contribute to nonrelapse mortality. They constitute a spectrum of diseases that can affect the parenchyma, airways, or vascular pulmonary components and specifically exclude cardiac and renal causes. The differential diagnoses of these entities differ as a function of time after hematopoietic cell transplantation. Specific diagnosis, prognosis, and optimal treatment remain challenging, although progress has been made in recent decades.

Abstract
The number of disorders that benefit from hematopoietic stem cell transplantation (HSCT) has increased, causing the overall number of HSCT to increase accordingly. Disorders treated by HSCT include malignancy, benign hematologic disorders, bone marrow failure syndromes, and certain genetic diagnoses. Thus, understanding the complications, diagnostic workup of complications, and subsequent treatments has become increasingly important. One such category of complications includes the pulmonary system. While the overall incidence of pulmonary complications has decreased, the morbidity and mortality of these complications remain high. Therefore, having a clear differential diagnosis and diagnostic workup is imperative. Pulmonary complications can be subdivided by time of onset and whether the complication is infectious or non-infectious. While most infectious complications have clear diagnostic criteria and treatment courses, the non-infectious complications are more varied and not always well understood. This review article discusses pulmonary complications of HSCT recipients and outlines current knowledge, gaps in knowledge, and current treatment of each complication. This article includes some adult studies, as there is a significant paucity of pediatric data.

Abstract
OBJECTIVES Hemoptysis is uncommon in children, even among the critically ill, with a paucity of epidemiological data to inform clinical decision-making. We describe hemoptysis-associated ICU admissions, including those who were critically ill at hemoptysis onset or who became critically ill as a result of hemoptysis, and identify predictors of mortality. DESIGN Retrospective cohort study. Demographics, hemoptysis location, and management were collected. Pediatric Logistic Organ Dysfunction-2 score within 24 hours of hemoptysis described illness severity. Primary outcome was inhospital mortality. SETTING Quaternary pediatric referral center between July 1, 2010, and June 30, 2017. PATIENTS Medical/surgical (PICU), cardiac ICU, and term neonatal ICU admissions with hemoptysis during or within 24 hours of ICU admission. INTERVENTIONS No intervention. MEASUREMENTS AND MAIN RESULTS There were 326 hemoptysis-associated ICU admissions in 300 patients. Most common diagnoses were cardiac (46%), infection (15%), bronchiectasis (10%), and neoplasm (7%). Demographics, interventions, and outcomes differed by diagnostic category. Overall, 79 patients (26%) died inhospital and 109 (36%) had died during follow-up (survivor mean 2.8 ± 1.9 yr). Neoplasm, bronchiectasis, renal dysfunction, inhospital hemoptysis onset, and higher Pediatric Logistic Organ Dysfunction-2 score were independent risk factors for inhospital mortality (p < 0.02). Pharmacotherapy (32%), blood products (29%), computerized tomography angiography (26%), bronchoscopy (44%), and cardiac catheterization (36%) were common. Targeted surgical interventions were rare. Of survivors, 15% were discharged with new respiratory support. Of the deaths, 93 (85%) occurred within 12 months of admission. For patients surviving 12 months, 5-year survival was 87% (95% CI, 78-92) and mortality risk remained only for those with neoplasm (log-rank p = 0.001). CONCLUSIONS We observed high inhospital mortality from hemoptysis-associated ICU admissions. Mortality was independently associated with hemoptysis onset location, underlying diagnosis, and severity of critical illness at event. Additional mortality was observed in the 12-month posthospital discharge. Future directions include further characterization of this vulnerable population and management recommendations for life-threatening pediatric hemoptysis incorporating underlying disease pathophysiology.

Abstract
INTRODUCTION Post-tonsillectomy hemorrhage is a serious postoperative complication, and its acute management can present a challenge for the emergency provider. Although various strategies have been proposed, guidance on the best approach for management of this condition in the emergency department (ED) setting remains limited. Anecdotal reports of the use of nebulized tranexamic acid (TXA) for management of tonsillar bleeding have emerged over the past two years. Two recently published case reports describe the successful use of nebulized TXA for stabilization of post-tonsillectomy hemorrhage in an adult and a pediatric patient. CASE SERIES Eight patients who presented to our ED with secondary post-tonsillectomy hemorrhage received nebulized TXA for hemostatic management. The most common TXA dose used was 500 milligrams, and all but one patient received a single dose of the medication in the ED. Hemostatic benefit was observed in six patients, with complete bleeding cessation observed in five cases. Interventions prior to nebulized TXA administration were attempted in three of the six patients and included ice water gargle, direct pressure with TXA-soaked gauze, and nebulized racemic epinephrine. All but one of the patients were taken to the operating room for definitive management after initial stabilization in the ED. CONCLUSION Nebulized TXA may offer a hemostatic benefit and aid in stabilization of tonsillectomy hemorrhage in the acute care setting, prior to definitive surgical intervention. Consideration of general principles of nebulization and aerosol particle size may be an important factor for drug delivery to the target tissue site.

Abstract
INTRODUCTION Massive hemoptysis is a life-threatening emergency that requires rapid evaluation and management. Recognition of this deadly condition, knowledge of the initial resuscitation and diagnostic evaluation, and communication with consultants capable of definitive management are key to successful treatment. OBJECTIVE The objective of this narrative review is to provide an evidence-based review on the management of massive hemoptysis for the emergency clinician. DISCUSSION Rapid diagnosis and management of life-threatening hemoptysis is key to patient survival. The majority of cases arise from the bronchial arterial system, which is under systemic blood pressure. Initial management includes patient and airway stabilization, reversal of coagulopathy, and identification of the source of bleeding using computed tomography angiogram. Bronchial artery embolization with interventional radiology has become the mainstay of treatment; however, unstable patients may require advanced bronchoscopic procedures to treat or temporize while additional information and treatment can be directed at the underlying pathology. CONCLUSION Massive hemoptysis is a life-threatening condition that emergency clinicians must be prepared to manage. Emergency clinicians should focus their management on immediate resuscitation, airway preservation often including intubation and isolation of the non-bleeding lung, and coordination of definitive management with available consultants including interventional radiology, interventional pulmonology, and thoracic surgery.

Abstract
Diffuse alveolar hemorrhage (DAH) is a life-threatening pulmonary complication in patients with hematologic malignancies or systemic autoimmune disorders. Pathologic findings show pulmonary capillaritis, bland hemorrhage, diffuse alveolar damage, and hemosiderin-laden macrophages, but in the majority of cases, pathogenesis remains unclear. Despite the severity and high mortality, the current treatment options for DAH remain empirical. Systemic treatment to control inflammatory activity including high-dose corticosteroids, cyclophosphamide, and rituximab and supportive care have been applied, but largely unsuccessful in critical cases. Activated recombinant factor VII (FVIIa) can achieve rapid local hemostasis and has been administered either systemically or intrapulmonary for the treatment of DAH. However, there is no randomized controlled study to evaluate the efficacy and safety, and the use of FVIIa for DAH remains open to debate. This review discusses the pathogenesis, diverse etiologies causing DAH, diagnosis, and treatments focusing on hemostasis using FVIIa. In addition, the risks and benefits of the off-label use of FVIIa in pediatric patients will be discussed in detail.

[PMID: 33014865 PMCID: PMC7509147 DOI: 10.3389/fonc.2020.01757] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Accepted: 08/05/2020] [Indexed: 12/21/2022] Open
Abstract
Pulmonary complications are common following hematopoietic cell transplantation (HCT) and contribute significantly to its morbidity and mortality. Diffuse alveolar hemorrhage is a devastating non-infectious complication that occurs in up to 5% of patients post-HCT. Historically, it carries a high mortality burden of 60–100%. The etiology remains ill-defined but is thought to be due to lung injury from conditioning regimens, total body irradiation, occult infections, and other comorbidities such as graft vs. host disease, thrombotic microangiopathy, and subsequent cytokine release and inflammation. Clinically, patients present with hypoxemia, dyspnea, and diffuse opacities consistent with an alveolar disease process on chest radiography. Diagnosis is most commonly confirmed with bronchoscopy findings of progressively bloodier bronchoalveolar lavage or the presence of hemosiderin-laden macrophages on microscopy. Treatment with glucocorticoids is common though dosing and duration of therapy remains variable. Other agents, such as aminocaproic acid, tranexamic acid, and activated recombinant factor VIIa have also been tried with mixed results. We present a review of diffuse alveolar hemorrhage with a focus on its pathogenesis and treatment options.
