RESUMO
BACKGROUND: The burden of hospitalizations and mortality for hemoptysis due to bronchiectasis is not well characterized. The primary outcome of our study was to evaluate in-hospital mortality in patients admitted with hemoptysis and bronchiectasis, as well as the rates of bronchial artery embolization, length of stay, and hospitalization costs. METHODS: The authors queried the Nationwide Inpatient Sample (NIS) claims database for hospitalizations between 2016 and 2017 using the ICD-10-CM codes for hemoptysis and bronchiectasis in the United States. Multivariable regression was used to evaluate predictors of in-hospital mortality, embolization, length of stay, and hospital costs. RESULTS: There were 8240 hospitalizations (weighted) for hemoptysis in the United States from 2016 to 2017. The overall in-hospital mortality was 4.5%, but higher in males compared to females. Predictors of in-hospital mortality included undergoing three or more procedures, age, and congestive heart failure. Bronchial artery embolization (BAE) was utilized during 2.1% of hospitalizations and was more frequently used in those with nontuberculous mycobacteria and aspergillus infections, but not pseudomonal infections. The mean length of stay was 6 days and the median hospitalization cost per patient was USD $9,610. Having comorbidities and procedures was significantly associated with increased length of stay and costs. CONCLUSION: Hemoptysis is a frequent indication for hospitalization among the bronchiectasis population. In-hospital death occurred in approximately 4.5% of hospitalizations. The effectiveness of BAE in treating and preventing recurrent hemoptysis from bronchiectasis needs to be explored.

BACKGROUND: Haemoptysis is a challenging symptom that can be associated with potentially life-threatening medical conditions. Follow-up is key in these patients to promptly detect new or misdiagnosed pathologic findings. Few prospective studies have evaluated long-term prognostic outcomes in patients with haemoptysis. Furthermore, the role played by antiplatelet and anticoagulant drugs on mortality and recurrence rates is unclear. The aim of this study was to assess mortality after 18 months of follow-up. Furthermore, the incidence of recurrence and the risk factors for recurrence and death were evaluated (including the role played by anticoagulant and antiplatelet drugs). METHODS: Observational, prospective, multicentre, Italian study. RESULTS: 451/606 (74.4%) recruited patients with haemoptysis completed the 18 months follow-up. 22/604 (3.6%) diagnoses changed from baseline to the end of the follow-up. 83/604 (13.7%) patients died. In 52/83 (62.7%) patients, death was the outcome of the disease which caused haemoptysis at baseline. Only the diagnosis of lung neoplasm was associated with death (OR (95%CI): 38.2 (4.2-347.5); p-value: 0.0001). 166 recurrences were recorded in 103/604 (17%) patients. The diagnosis of bronchiectasis was significantly associated with the occurrence of a recurrence (OR (95% CI): 2.6 (1.5-4.3)); p-value < 0.0001). Anticoagulant, antiaggregant, and anticoagulant plus antiaggregant drugs were not associated with an increased risk of death and recurrence. CONCLUSIONS: Our study showed a low mortality rate in patients with haemoptysis followed-up for 18 months. Pulmonary malignancy was the main aetiology and the main predictor of death, whereas bronchiectasis was the most frequent diagnosis associated with recurrence. Antiplatelet and/or anticoagulant therapy did not change the risk of death or recurrence. Follow-up is recommended in patients initially diagnosed with lower airways infections and idiopathic bleeding. TRIAL REGISTRATION: NCT02045394.

BACKGROUND: Although tranexamic acid (TXA), a readily accessible antifibrinolytic agent, is widely adopted in hemorrhage scenarios, its role on mortality in patients with hemoptysis remains uncertain. New evidence is yet to be generated to evaluate the risk of mortality after using TXA in patients with hemoptysis. METHODS: PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus databases were searched from inception to May 2020. Randomized controlled trials and observational studies that evaluated the effect of TXA on patients with hemoptysis were included. Data were independently extracted by 2 reviewers and synthesized using a random-effects model. MAIN RESULTS: Five studies with a total of 20,047 patients were analyzed. When compared with the control, administration of TXA was associated with a reduction in short-term mortality (risk ratio = 0.78, 95% confidence interval [CI] 0.72-0.85; I2 = 0), shorter bleeding time (mean difference =â-â24.61âhours, 95% CIâ-â35.96 to -13.26, I2 = 0), shorter length of hospital stay (mean difference = -1.94âdays, 95% CI -2.48 to -1.40, I2 = 0), and lower need for intervention (risk ratio = 0.38, 95% CI 0.16-0.87, I2 = 0) in patients with hemoptysis. Compared with control, administration of TXA did not cause increased major or minor adverse effects. CONCLUSIONS: TXA provided benefits in terms of a lower short-term mortality rate, less bleeding time, shorter length of hospital stays, and less need for intervention in patients with hemoptysis. Use of TXA was not associated with increased adverse effects.

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.

OBJECTIVES: Hemoptysis, a symptom common across various respiratory diseases, can cause airway obstruction leading to a life-threatening condition. Arterial embolization has been used to control bleeding from the lower airways. However, limited studies have evaluated its effects on in-hospital mortality in patients with hemoptysis requiring mechanical ventilation. The objective of this study was to clarify whether early intervention by arterial embolization reduced mortality in mechanically ventilated patients with hemoptysis. DESIGN: Retrospective cohort study from July 2010 to March 2017. SETTING: More than 1,200 acute-care hospitals, comprising approximately 90% of all tertiary-care emergency hospitals in Japan. PATIENTS: The study cohort was patients with pulmonary diseases hospitalized for hemoptysis and mechanically ventilated within 2 days of admission. INTERVENTIONS: We compared patients who had undergone arterial embolization within 3 days of endotracheal intubation (early embolization group) with patients who did not (control group). MEASUREMENTS AND MAIN RESULTS: A total of 12,287 patients with hemoptysis requiring mechanical ventilation were analyzed. After 1:4 propensity score matching, there were 226 and 904 patients in the early embolization and control groups, respectively. The early embolization group was associated with lower 7-day and 30-day mortalities (7-d mortality: 1.3% vs 4.0%; odds ratio, 0.39; 95% CI, 0.16-0.97; p = 0.044 and 30-d mortality: 7.5% vs 16.8%; odds ratio, 0.45; 95% CI, 0.28-0.73; p = 0.001) and shorter duration of mechanical ventilation (median 6 d, interquartile range 4-13 d vs 8 d, interquartile range 4-19 d; p = 0.003) compared with the control group. CONCLUSIONS: Our results show that early intervention by arterial embolization may be effective in reducing 7-day and 30-day mortalities in patients with life-threatening hemoptysis requiring mechanical ventilation.

BACKGROUND: Multidetector computed tomography (MDCT) angiography is a useful examination to detect the source of the bleeding in patients with hemoptysis. The aim of the study was to prospectively evaluate the role and clinical efficacy of MDCT angiography before bronchial artery embolization (BAE) for the management of hemoptysis, and to investigate the predictors of early recurrence. METHODS: It is a double-center study which included 57 hemoptysis patients undergoing MDCT angiography prior to BAE from August 2019 to July 2020. A prospective analysis of culprit arteries detected by MDCT angiography allowed an evaluation of the role of this technique. A follow-up was done to assess the efficacy of BAE with preprocedural MDCT angiography and to explore the risk factors of early recurrent hemoptysis. RESULTS: The accuracy of MDCT angiography in the identification of culprit arteries was as high as 97.5%. The average number of total culprit arteries per patient was 2.75 ± 1.73. Among which, the average numbers of culprit ectopic bronchial arteries (BAs) and non-bronchial systemic arteries (NBSAs) per patient were 0.21 ± 0.41 and 1.04 ± 1.57, respectively. The immediate clinical success rate, total hemoptysis recurrence rate, and early hemoptysis recurrence rate of BAE following MDCT angiography were 94.7, 18.5, 16.7%, respectively. Aspergilloma (HR = 6.63, 95% CI: 1.31-33.60, p = 0.022) was associated with an increase in the risk of early recurrence. CONCLUSIONS: MDCT angiography should be performed before BAE for the management of hemoptysis. Aspergilloma was an independent predictor for early recurrence.

BACKGROUND: Hemoptysis, a common symptom of different lung diseases, engenders shortness of breath and increased mortality. Tranexamic acid (TXA), a commonly used antifibrinolytic agent, can control bleeding. However, the effects of its use on pulmonary hemorrhage have rarely been discussed. OBJECTIVE: We conducted this systematic review and meta-analysis of randomized controlled trials (RCTs) of TXA for hemoptysis to investigate its effectiveness in reducing hemoptysis volume and duration. METHODS: We searched the Cochrane Library, Embase, PubMed (including MEDLINE), and Scopus databases for relevant RCTs. Two of the authors individually assessed study quality by using the Cochrane risk-of-bias (RoB) 2.0 tool, and the pooled results were evaluated using RevMan 5.3. RESULTS: We obtained 617 articles, of which four RCTs met eligibility criteria. The pooled results demonstrated no significant differences in bleeding duration or hemoptysis resolution between the TXA and control groups. Nevertheless, TXA use reduced bleeding volume (mean difference [MD] = - 56.21 mL; 95% CI - 94.70 to - 17.72 mL), further intervention risk (Peto odds ratio = 0.24; 95% CI 0.08-0.67; I2 = 0%), and length of hospital stay (MD = - 1.62 days; 95% CI - 2.93 to - 0.31; I2 = 0%). CONCLUSION: TXA use was observed to reduce bleeding volume, further intervention risk, and length of hospital stay in patients with hemoptysis; however, our results may have low statistical power because of limited sample size. Additional large-scale RCTs are thus warranted to confirm the effectiveness and safety of TXA use.

OBJECTIVE: Massive hemoptysis (MH) has a high mortality rate. Therapeutic options include bronchoscopy for endobronchial lesions, bronchial artery embolization (BAE), and emergency surgery. Scant options exist for patients who are not candidates for these modalities. Culprit bronchial segment occlusion is an option to prevent "spillover flooding â hypoxia." Applying this concept, we describe a case series of MH control using a novel bronchoscopically inserted customized endobronchial silicone blocker (CESB). We analyzed the safety and efficacy of CESBs in a select subset of patients with MH. METHODS: Inclusion criteria were patients with MH who were unstable for surgery/BAE, failed BAE, or relatively contraindicated/refused BAE. CESBs were manufactured on-site by modifying silicone stents, inserted using rigid bronchoscopy and reinforced with glue. The CESB was removed after 6 weeks when possible. A successful outcome was defined as immediate bleeding control with no recurrence after removal. RESULTS: Over 4.5 years, 13 episodes of MH in 12 patients meeting the criteria specified earlier were treated with CESBs. Seven of 12 patients had tuberculosis, 4 active and 3 inactive. One patient had mucormycosis, 1 post-lobectomy, 1 endobronchial renal cell carcinoma, 1 fibrosing mediastinitis, and 1 patient had metastatic laryngeal Ca. Eight of 12 patients were taken for primary-CESB placement. Four of 12 patients were sent for BAE, which was unsuccessful, and rescue-CESB was done for definitive management. The success rate, as defined earlier, was 92.3%, with no deaths from MH. CONCLUSIONS: Innovative bronchoscopically inserted CESBs are an effective strategy in MH when patients are unstable or fail conventional management.

PURPOSE: To review safety and efficacy of bronchial artery embolization (BAE) for treatment of hemoptysis in adult patients with cystic fibrosis (CF) and to report 30-day, 1-year, and 3-year outcomes. MATERIALS AND METHODS: Between January 2001 and April 2018, 242 patients with CF were evaluated for hemoptysis. Thirty-eight BAEs were performed in 28 patients with hemoptysis. Technical success was defined as freedom from repeat embolization and hemoptysis-related mortality. Clinical success was defined as freedom from repeat embolization and mortality from any cause. Technical and clinical success were examined at 30 days, 1 year, and 3 years after initial BAE. Mean patient age was 32 years, and median follow-up was 4.8 years (range, 10 mo to 16.7 y). RESULTS: Technical and clinical success rates at 30 days were 89% (25/28) and 82% (23/28), respectively. Success rates at 1 year were 86% (24/28) and 79% (22/28), respectively, and at 3 years were 82% (23/28) and 75% (21/28), respectively. The 30-day overall complication rate was 7.9% (3/38) with 2.6% (1/38) major complication rate and 5.2% (2/38) minor complication rate. Overall 3-year mortality rate was 25% (7/28). CONCLUSIONS: BAE is safe and effective in patients with CF presenting with life-threatening hemoptysis. BAE results in high rates of long-term technical and clinical success in this patient population despite progressive chronic disease. Repeat embolization is necessary only in a minority of patients.

BACKGROUND: Although tranexamic acid is widely used in patients with haemoptysis, whether it improves mortality has not been well investigated. The aim of this study was to evaluate the effect of tranexamic acid on in-hospital mortality among patients with haemoptysis. METHODS: This was a retrospective study using data from the Japanese Diagnosis Procedure Combination inpatient database. We identified all cases of emergency admission due to haemoptysis from July 2010 to March 2017. Patients were divided into two groups: a control group, and a tranexamic acid group (those who received tranexamic acid on the day of admission). The primary outcome was in-hospital mortality, with secondary outcomes of hospital stay length and total healthcare cost. The data were evaluated using a propensity score matching analysis. RESULTS: Among 28,539 included patients, 17,049 patients received tranexamic acid and 11,490 patients did not. Propensity score analysis generated 9933 matched pairs. Compared to the control group, patients in the tranexamic acid group had significantly lower in-hospital mortality (11.5% vs. 9.0%; risk difference, - 2.5%; 95% confidence interval (CI), - 3.5 to - 1.6%), shorter hospital stays (18 ± 24 days vs. 16 ± 18 days; risk difference, - 2.4 days; 95% CI, - 3.1 to - 1.8 days), and lower total healthcare costs ($7573 ± 10,085 vs. $6757 ± 9127; risk difference, $- 816; 95% CI, $- 1109 to - 523). CONCLUSIONS: Tranexamic acid may reduce in-hospital mortality among patients with haemoptysis requiring emergency admission.

OBJECTIVES: To describe the etiologies of hemoptysis in patients without pre-existing bronchiectasis or cardiac disease; to assess odds of recurrent hemoptysis by diagnostic category; and to assess odds of mortality by diagnostic category. STUDY DESIGN: This retrospective case series included all patients with hemoptysis documented during an admission to Boston Children's Hospital from January 1, 2007 to June 1, 2017. Patients with bronchiectasis, congenital heart disease, primary pulmonary hypertension, bleeding above the glottis, hemoptysis before 38 weeks of corrected gestational age, hematemesis, foreign body, and trauma were excluded. Patients were also characterized by coagulation status. Primary outcomes were recurrent hemoptysis and death. Univariate analysis was performed to determine ORs for recurrence and death per diagnostic category with infection as the reference category. RESULTS: In total, 257 patients met study criteria and were analyzed. The most common causes of hemoptysis were infection (n = 122), neoplasm (n = 58), and other diagnoses (n = 49). Of the patients with infection, recurrence was 28% and all-cause mortality was 12%. Neoplasm had lower odds of recurrence (OR 0.3, P = .012) but higher odds of mortality (OR 15.8, P < .001). Thrombocytopenia had lower odds of recurrence (OR 0.2, P = .005) but higher odds of mortality (OR 5.9, P < .001). Patients with a tracheostomy had higher odds of recurrence (OR 6.3, P < .001), but lower odds of death (OR 0.4, P = .042). CONCLUSIONS: This study confirms that infection is the most common cause of hemoptysis in patients without severe underlying pulmonary or cardiac disease. Hemoptysis associated with neoplasm and/or thrombocytopenia confers mortality risk. Tracheostomy confers risk of recurrence. Future prospective research on diagnoses associated with hemoptysis is warranted.

OBJECTIVES: Managing hemoptysis in chronic thromboembolic pulmonary hypertension can be challenging due to the difficulties in maintaining coagulation homeostasis in affected patients. In this study, we evaluated the efficacy and safety of bronchial artery embolization in treating hemoptysis in chronic thromboembolic pulmonary hypertension patients. DESIGN: Pilot, prospective cohort study. SETTING: A large respiratory medical institute. PATIENTS: From January 1, 2012, to December 31, 2017, hospitalized chronic thromboembolic pulmonary hypertension patients were eligible for inclusion. Patients with pulmonary hypertension caused by other conditions, or who failed to participate in the follow-up were excluded. INTERVENTIONS: Hemoptysis in chronic thromboembolic pulmonary hypertension patients was treated with or without bronchial artery embolization based on whether the bleeding could be stopped with medication alone and patient willingness for bronchial artery embolization treatment. MEASUREMENTS AND MAIN RESULTS: A total of 328 patients diagnosed with chronic thromboembolic pulmonary hypertension were consecutively collected, 317 patients were completed the follow-up. There were 15 chronic thromboembolic pulmonary hypertension patients with hemoptysis in total, and the occurrence rate of hemoptysis in chronic thromboembolic pulmonary hypertension patients was 4.7%. Among the hemoptysis chronic thromboembolic pulmonary hypertension patients, 10 (67%) underwent bronchial artery embolization, and five (33%) were treated with medication only. The median follow-up period for hemoptysis patients was 7.6 months. In patients underwent bronchial artery embolization treatment, oxygenation index and right heart function showed no significant difference between pre bronchial artery embolization and post bronchial artery embolization. Hemoptysis relapse (20% vs 80%; p = 0.025) and hemoptysis-related mortality (0% vs 40%; p = 0.032) were significantly lower, whereas the overall survival (90% vs 40%; p = 0.040) was higher in patients treated with bronchial artery embolization than in patients treated without bronchial artery embolization. CONCLUSIONS: Bronchial artery embolization procedure demonstrated effectiveness and safety to treat hemoptysis in chronic thromboembolic pulmonary hypertension patients at our center, but further controlled studies are needed before it can be considered as an effective therapy for these patients.

OBJECTIVES: To compare the average number of culprit arteries per patient, clinical success rate, and hemoptysis-free survival rate between hemoptysis patients with multidetector computed tomography (MDCT) angiography prior to bronchial artery embolization (BAE) and those without preprocedural MDCT angiography METHODS: This retrospective study was approved by the institutional review board with waiver of patient informed consent. From September 2012 to March 2017, 157 consecutive hemoptysis patients had been undergoing BAE. Among them, 106 patients received preprocedural MDCT angiography (MDCT group), while 51 patients did not receive preprocedural MDCT angiography (control group). The average number of culprit arteries per patient, clinical success rate, and hemoptysis-free survival rate were compared between the two groups. RESULTS: The average number of culprit ectopic bronchial arteries and that of non-bronchial systemic arteries originating from the subclavian and internal mammary arteries per patient in the MDCT group were both significantly higher than those in the control group (0.15 ± 0.51 vs 0.04 ± 0.20, p = 0.022, and 0.17 ± 0.56 vs 0.08 ± 0.39, p = 0.040, respectively). The clinical success rate of BAE with preprocedural MDCT angiography tended to be higher than that without MDCT angiography (97.2 vs 88.2%, p = 0.057). Importantly, patients in the MDCT group had a significantly higher hemoptysis-free early survival rate compared to those in the control group (96.1 vs 86.7%, p = 0.031). CONCLUSIONS: Preprocedural MDCT angiography helps detect culprit ectopic bronchial arteries and non-bronchial systemic arteries originating from subclavian and internal mammary arteries during BAE, and can improve the hemoptysis-free early survival rate, which could be recommended as a regular examination prior to BAE in patients with hemoptysis. KEY POINTS: ⢠Preprocedural MDCT angiography helps detect culprit ectopic bronchial arteries and NBSAs originating from subclavian and internal mammary arteries during BAE. ⢠Conducting MDCT angiography prior to BAE can improve hemoptysis-free early survival rate in hemoptysis patients.

OBJECTIVE: This study aimed to analyze the clinical characteristics and prognosis of pediatric idiopathic pulmonary hemosiderosis (IPH). METHODS: Pediatric IPH cases that were diagnosed at West China Second University Hospital, Sichuan University between 1996 and 2017 were reviewed. Follow-up data from 34 patients were collected. RESULTS: A total of 107 patients were included (42 boys and 65 girls). The median age was 6 years at diagnosis. The main manifestations of the patients were as follows: anemia (n = 100, 93.45%), cough (n = 68, 63.55%), hemoptysis (n = 61, 57%), fever (n = 23, 21.5%), and dyspnea (n = 23, 21.5%). There were relatively few pulmonary signs. The positive rates of hemosiderin-laden macrophages in sputum, gastric lavage fluid, and bronchoalveolar lavage fluid were 91.66%, 98.21%, and 100%, respectively. Seventy-nine patients were misdiagnosed. A total of 105 patients were initially treated with glucocorticoids, among whom 102 survived and three died. Among the followed up patients, two died and 32 survived, among whom 10 presented with recurrent episodes. CONCLUSIONS: The classic triad of pediatric IPH is not always present. The rates of misdiagnosis and recurrence of IPH are high. Early recognition and adequate immunosuppressive therapy are imperative for improving prognosis of IPH.

BACKGROUND: Diffuse Alveolar Hemorrhage (DAH) is a rare and potentially life-threatening clinical syndrome whose early recognition is essential. OBJECTIVES: Characterization of patients with DAH and comparison of presentation and evolution of the disease according to etiology. METHODS: We retrospectively reviewed the clinical records of patients admitted to our hospital over a 7-year period with DAH. Criteria for DAH (1+2): 1 - hemoptysis and/or pulmonary infiltrates and/or anemia (DAH triad); 2 - hemorrhagic bronchoalveolar lavage (BAL) or siderophagic alveolitis. DAH was grouped in immune and nonimmune and the course of disease was compared. RESULTS: We included 24 patients admitted with DAH, of which 11 had an immune cause: p-ANCA vasculitis (n=7), Systemic Lupus Erythematosus (n=2), c-ANCA vasculitis (n=1), Rheumatoid Arthritis (n=1) and 13 had a nonimmune cause: heart disease (n=6), amiodarone toxicity (n=2), clotting disorder (n=2), cannabis toxicity (n=1), S. aureus infection (n=1) and idiopathic (n=1). Patients with nonimmune DAH were significantly older than those with immune DAH (67.9±18.1 vs 56.6±18.8 years, p=0.042). DAH triad was observed in 54% of all patients, hemoptysis in 67%, anemia in 79%, and pulmonary infiltrates in all cases. Patients with immune DAH had more frequently pulmonary-renal syndrome (p<0.001), kidney failure (p=0.048), shock (p=0.049) and needed more frequently admition in ICU (p=0.039) and blood transfusion (p=0.043). Hospital length of stay was superior in immune group (29.5±20.0 vs 19.5±14.3 days, p=0.047). In-hospital mortality was exclusive to immune DAH (12.5%). CONCLUSIONS: Patients with DAH due to immune causes were significantly younger, had more severe presentations of the disease and worst outcomes.

BACKGROUND: Tranexamic acid (TA) is an antifibrinolytic drug currently used systemically to control bleeding. To date, there have been no prospective studies of the effectiveness of inhaled TA for the treatment of hemoptysis. OBJECTIVES: The goal of this study was to prospectively assess the effectiveness of TA inhalations (ie, nebulized TA) for hemoptysis treatment. METHODS: This analysis was a double-blind, randomized controlled trial of treatment with nebulized TA (500 mg tid) vs placebo (normal saline) in patients admitted with hemoptysis of various etiologies. Patients with massive hemoptysis (expectorated blood > 200 mL/24 h) and hemodynamic or respiratory instability were excluded. Mortality and hemoptysis recurrence rate were assessed at 30 days and following 1 year. RESULTS: Forty-seven patients were randomized to receive TA inhalations (n = 25) or normal saline (n = 22). TA was associated with a significantly reduced expectorated blood volume starting from day 2 of admission. Resolution of hemoptysis within 5 days of admission was observed in more TA-treated patients than in those receiving placebo (96% vs 50%; P < .0005). Mean hospital length of stay was shorter for the TA group (5.7 ± 2.5 days vs 7.8 ± 4.6 days; P = .046), with fewer patients requiring invasive procedures such as interventional bronchoscopy or angiographic embolization to control the bleeding (0% vs 18.2%; P = .041). No side effects were noted in either group throughout the follow-up period. In addition, a reduced recurrence rate was noted at the 1-year follow-up (P = .009). CONCLUSIONS: TA inhalations can be used safely and effectively to control bleeding in patients with nonmassive hemoptysis.

This report describes a series of ten cases of fulminant pulmonary haemorrhage in dogs following envenomation by the eastern brown snake (Pseudonaja textilis) in south eastern Queensland, Australia. All cases were presented for veterinary treatment during 2011-2018 at a specialist veterinary emergency centre. Each case received prompt antivenom treatment and supportive care. Pulmonary haemorrhage was diagnosed based on clinical examination; overt haemoptysis; thoracic radiographic demonstration of a diffuse alveolar pattern; and, the presence of venom induced consumptive coagulopathy. The median elapsed time from hospital admission to onset of haemoptysis was 2 h (range 0-18 h). In 80% (8/10) of cases endotracheal intubation was required, whilst 20% (2/10) were successfully treated with mask oxygen supplementation alone, and 40% (4/10) received mechanical ventilation; but only 25% (1/4) of these survived to hospital discharge. Fresh frozen canine plasma was administered to 70% (7/10) of cases and 43% (3/7) of these survived. Of the total number of cases presented for treatment, 30% (3/10) survived to hospital discharge, 60% (6/10) were euthanised due to poor prognosis and 10% (1/10) died from cardiac arrest. Initial serum brown snake venom antigen levels were retrospectively measured from frozen serum samples by venom specific sandwich ELISA in two dogs at 154 ng/mL (survived) and 3607 ng/mL (euthanised); no free venom was detected post-antivenom. Dogs that survived were discharged from hospital without apparent complications. Pulmonary haemorrhage is an uncommon event following envenomation by P. textilis in dogs and has not been described in similarly envenomed humans. This case series highlights the potential for fulminant and fatal pulmonary haemorrhage in dogs following eastern brown snake envenomation.

PURPOSE: To evaluate the safety and efficacy of endovascular management of pulmonary artery lesions caused by lung tumors. MATERIALS AND METHODS: Nineteen patients (15 men, 4 women; average age: 60.3 years, range, 51-86 years) treated for massive or recurrent hemoptysis with transarterial pulmonary artery embolization between 2010 and 2016 were included in this multicenter, retrospective study. Inclusion criteria were: patients with lung cancer and at least 1 episode of hemoptysis with a pulmonary artery lesion detected by computed tomography (CT) angiography or after failed bronchial artery embolization. No patient undergoing pulmonary embolization for a lung tumor was excluded. Technical success, clinical success, and complications were recorded. The survival curve was estimated using the Kaplan-Meier method RESULTS: Mean follow-up was 188.1 days (range, 0-1440 days). Primary and assisted technical success rates were 73.7% (14/19) and 84.2% (16/19), respectively. Two patients died during the procedure due to massive hemoptysis and cardiac arrest, and 1 patient was treated with surgery. All patients with technical success achieved clinical success without further bleeding. No complications were noted, and no pulmonary infarction was detected on CT scan during follow-up. Survival rates after embolization at 1 and 3 months were 67% (95% confidence interval [CI]: 40%-90%) and 46% (95% CI: 23%-80%), respectively, with 36.8% (n = 7) of the patients still alive at the end of the study. CONCLUSIONS: Embolization is an effective and safe treatment of lung tumors with pulmonary arterial bleeding.

OBJECTIVE: The aim of this retrospective study was to observe the long-term outcomes of conservative treatment and bronchial artery embolization (BAE) in patients with mild hemoptysis and to analyze the risk factors associated with hemoptysis recurrence. METHODS: Patients with mild hemoptysis from January 2005 to January 2016 were enrolled in this study. The patients' medical records, including smoking history, etiologic diseases, bronchoscopic findings, mortality, BAE information, and follow-up data of recurrent hemoptysis, were reviewed and analyzed. RESULTS: A total of 288 patients with mild hemoptysis were included in this study. Of them, 71 patients (24.7%) underwent BAE and 217 patients (75.3%) were treated conservatively. The clinical success rate of BAE was 98.6%, with a low minor complication rate of 5.6%. Bronchoscopy before treatments was performed in 237 patients (82.3%). Fifty-five patients (19.1%) experienced recurrent hemoptysis during a median follow-up period of 2.4years (interquartile range: 1.0-4.4years). Patients who showed active bleeding or blood clots on bronchoscopy had a significantly lower recurrence-free survival rate than patients with no bronchoscopic evidence of bleeding or blood clots (p=0.012). The risk factors affecting recurrence were heavy smoking (p=0.002, hazard ratio [HR]: 3.57), aspergillosis (p=0.035, HR: 6.01), and bronchoscopic findings of active bleeding (p=0.016, HR: 3.29) or blood clots (p=0.012, HR: 2.77). CONCLUSIONS: The recurrence rate of hemoptysis was not negligible in patients with mild hemoptysis. BAE can be considered in patients with a high risk of recurrence.

Massive hemoptysis is a life-threatening condition often defined as coughing up 300-600mL of blood in 24 hours in an adult, or >8mL/kg in 24 hours in a child. Although the definition is controversial, one should view massive hemoptysis as any volume of expectorated blood that can cause respiratory failure. This is because mortality in the setting of hemoptysis is usually associated with asphyxiation, rather than exsanguination. Massive hemoptysis accounts for only about 5% of cases of hemoptysis, but when treated conservatively, has a reported mortality rate between 50% and 85%. Etiologies vary widely based on demographics. In children, infectious causes predominate in developing countries, and cystic fibrosis predominates among children of European descent. In adults, malignancy, bronchiectasis, and chronic infection are the most common causes. Treatment begins with resuscitation and airway protection, followed by minimally invasive bronchoscopic and endovascular techniques. Surgical interventions are considered last line therapy due to mortality rates of 37%-43% in the setting of massive hemoptysis. Bronchial artery embolization is now considered the treatment of choice for massive hemoptysis.
