Hemorrhage in a patient with Bronchial Dieulafoy's disease and associated pulmonary fibrosis: A case report.

Background: Bronchial Dieulafoy's disease (BDD) is a rare vascular anomaly that was first described in 1995. The main symptom is recurrent hemoptysis. It can be diagnosed through angiography, bronchoscopy, and sometimes histology and endobronchial ultrasound scan (EBUS). Treatment includes embolization and surgery. Case presentation: A 77-year-old male with dyspnea and CT scan revealing an interstitial pattern underwent bronchoscopy for bronchoalveolar lavage (BAL). During bronchoscopy, a protruding white non-pulsatile lesion was biopsied. The biopsy triggered a massive hemorrhage, which required an embolization procedure. Bronchial Dieulafoy's disease was diagnosed. There was no need for surgery in this case. The interstitial pattern was diagnosed as idiopathic pulmonary fibrosis. Conclusions: This report describes a novel case of BDD leading to bronchial hemorrhage. Considering the endoscopic differential diagnosis, including rather frequent carcinoid tumor and broncholithiasis, we highlight the need for extreme caution when considering endoscopic biopsy of protruding white lesions. Indeed, biopsy - or even contact - with a BDD lesion is frequently associated with massive hemorrhage. According to our review, BDD is the most hemorrhage-prone lesion when biopsied, associated with significant bleeding in 90% of cases and 30% mortality, compared with significant bleeding in only 2.6% of carcinoid tumors and 3.1% of broncholithiasis cases.This case of BDD is also original since associated with idiopathic pulmonary fibrosis. It is to our knowledge the first time that such an association has been reported.

Chronic respiratory diseases are predictors of severe outcome in COVID-19 hospitalised patients: a nationwide study.

BACKGROUND: Influenza epidemics were initially considered to be a suitable model for the COVID-19 epidemic, but there is a lack of data concerning patients with chronic respiratory diseases (CRDs), who were supposed to be at risk of severe forms of COVID-19. METHODS: This nationwide retrospective cohort study describes patients with prior lung disease hospitalised for COVID-19 (March-April 2020) or influenza (2018-2019 influenza outbreak). We compared the resulting pulmonary complications, need for intensive care and in-hospital mortality depending on respiratory history and virus. RESULTS: In the 89 530 COVID-19 cases, 16.03% had at least one CRD, which was significantly less frequently than in the 45 819 seasonal influenza patients. Patients suffering from chronic respiratory failure, chronic obstructive pulmonary disease, asthma, cystic fibrosis and pulmonary hypertension were under-represented, contrary to those with lung cancer, sleep apnoea, emphysema and interstitial lung diseases. COVID-19 patients with CRDs developed significantly more ventilator-associated pneumonia and pulmonary embolism than influenza patients. They needed intensive care significantly more often and had a higher mortality rate (except for asthma) when compared with patients with COVID-19 but without CRDs or patients with influenza. CONCLUSIONS: Patients with prior respiratory diseases were globally less likely to be hospitalised for COVID-19 than for influenza, but were at higher risk of developing severe COVID-19 and had a higher mortality rate compared with influenza patients and patients without a history of respiratory illness.

Characteristics and Long-term Outcomes of Pulmonary Venoocclusive Disease Induced by Mitomycin C.

BACKGROUND: Pulmonary venoocclusive disease (PVOD) is an uncommon form of pulmonary hypertension (PH) predominantly characterized by pulmonary vein and capillary involvement. An association between chemotherapy, in particular mitomycin C (MMC), and PVOD has been reported. RESEARCH QUESTION: What are the characteristics of MMC-induced PVOD, and what is the prognosis for patients with MMC-induced PVOD? STUDY DESIGN AND METHODS: We report the clinical, functional, radiologic, and hemodynamic characteristics at diagnosis and outcomes of patients with PVOD from the French PH Registry after exposure to MMC. The results are expressed as the median (minimum-maximum). RESULTS: From June 2011 to December 2018, 17 incident cases of MMC-induced PVOD were identified. At diagnosis, these patients had severe clinical and functional impairment, with 12 patients having a New York Heart Association (NYHA) functional class of III or IV and a 6-min walk distance of 220 (0-465) m. Right heart catheterization confirmed severe precapillary PH with a mean pulmonary artery pressure of 38 (30-52) mm Hg, a cardiac index of 2.2 (1.5-4) L/(min × m2), and pulmonary vascular resistance of 8.3 (5.1-14.5) Wood units. The diffusing capacity of the lungs for carbon monoxide was markedly decreased at 31% (20%-51%) of the theoretical values associated with severe hypoxemia. MMC was withdrawn for all patients, and 14 patients received specific pulmonary arterial hypertension (PAH) therapies. Among these patients, mild but statistically insignificant improvements were observed in NYHA functional class (P = .10), 6-min walk distance (P = .09), and pulmonary vascular resistance (-4.7 Wood units; P = .052) at reassessment (median delay of 4.8 months). Three patients experienced pulmonary edema requiring the cessation or reduction of PAH treatment. The median overall survival was 20 months, and the 6-, 12-, and 24-month survival rates were 76%, 58%, and 18%, respectively. INTERPRETATION: PVOD after MMC treatment is a rare but life-threatening complication associated with a poor prognosis despite MMC withdrawal and PAH-specific therapy.

Cardiovascular prevention and at-risk behaviours in a large population of amateur rugby players.

BACKGROUND AND AIM: We aimed to investigate cardiovascular risk factors and health behaviours prospectively in a large population of French amateur rugby players. METHODS: An anonymous questionnaire was displayed to rugby players aged over 12 years enrolled in the 2014-2015 French amateur rugby championship from the Burgundy region (n = 5140). Questions addressed awareness on: (a) cardiovascular prevention; (b) tobacco, alcohol and highly caffeinated beverages consumption; and (c) adherence to prevention guidelines (ECG checks, training in basic life support, avoidance of sports practice during fever/infectious episodes). RESULTS: Among the 640 participants who completed the questionnaires, most were male (90%) and were aged under 35 years (80%). Almost half had basic life support training (42%), but only a minority attended an ECG check-up before licensing (37%), and only a few were aware of the cardiovascular prevention information campaign (17%), similarly across the age groups. Surprisingly, playing rugby with fever was commonly reported (44%) and was even more frequent in young women (55%). A high number of respondents were current smokers (35%), of whom most reported consumption less than 2 hours before/after a rugby session. Alcohol drinkers were frequent (69%), of whom most (79%) drank alcohol less than 2 hours before/after a match. Highly caffeinated beverages consumption (34%) was high, particularly in younger players (39%). Half highly caffeinated beverages consumption was in the setting of a rugby session, even greater in women and mainly motivated by performance enhancement (34%). CONCLUSION: Our findings from a representative regional cohort may help to identify targets for cardiovascular prevention through the development of educational programmes aiming to improve the knowledge and behaviour of amateur rugby players.

Increasing burden of noninfectious lung disease in persons living with HIV: a 7-year study using the French nationwide hospital administrative database.

An overall reduction in the incidence of AIDS and a change in the spectrum of lung disease have been noticed in persons living with HIV (PLHIV). Our aim was to provide an epidemiological update regarding the prevalence of lung diseases in PLHIV hospitalised in France.We analysed the prevalence of lung disease in PLHIV hospitalised in France from 2007 to 2013, from the French nationwide hospital medical information database, and assessed the association between HIV and incident noninfectious disease over 4 years of follow-up.A total of 52 091 PLHIV were hospitalised in France between 2007 and 2013. Among PLHIV hospitalised with lung disease, noninfectious lung diseases increased significantly from 45.6% to 54.7% between 2007 and 2013, whereas the proportion of patients with at least one infectious lung disease decreased significantly. In 2010, 10 067 prevalent hospitalised PLHIV were compared with 8 244 682 hospitalised non-PLHIV. In 30-49-year-old patients, HIV infection was associated with chronic obstructive pulmonary disease (COPD), chronic respiratory failure, emphysema, lung fibrosis and pulmonary arterial hypertension (PAH) even after adjustment for smoking.The emergence of noninfectious lung disease, in particular COPD, emphysema, lung fibrosis, PAH and chronic respiratory disease, in PLHIV would justify mass screening in this population.

Haemoptysis in adults: a 5-year study using the French nationwide hospital administrative database.

Haemoptysis is a serious symptom with various aetiologies. Our aim was to define the aetiologies, outcomes and associations with lung cancer in the entire population of a high-income country.This retrospective multicentre study was based on the French nationwide hospital medical information database collected over 5 years (2008-2012). We analysed haemoptysis incidence, aetiologies, geographical and seasonal distribution and mortality. We studied recurrence, association with lung cancer and mortality in a 3-year follow-up analysis.Each year, ~15 000 adult patients (mean age 62 years, male/female ratio 2/1) were admitted for haemoptysis or had haemoptysis as a complication of their hospital stay, representing 0.2% of all hospitalised patients. Haemoptysis was cryptogenic in 50% of cases. The main aetiologies were respiratory infections (22%), lung cancer (17.4%), bronchiectasis (6.8%), pulmonary oedema (4.2%), anticoagulants (3.5%), tuberculosis (2.7%), pulmonary embolism (2.6%) and aspergillosis (1.1%). Among incident cases, the 3-year recurrence rate was 16.3%. Of the initial cryptogenic haemoptysis patients, 4% were diagnosed with lung cancer within 3 years. Mortality rates during the first stay and at 1 and 3 years were 9.2%, 21.6% and 27%, respectively.This is the first epidemiological study analysing haemoptysis and its outcomes in an entire population. Haemoptysis is a life-threatening symptom unveiling potentially life-threatening underlying conditions.

[Drug-induced interstitial lung diseases]. / Pneumopathies interstitielles iatrogéniques.

Drug-induced infiltrative lung disease may manifest as variable clinical radiological patterns, including subacute or chronic interstitial pneumonia, pulmonary fibrosis, eosinophilic pneumonia, organising pneumonia, pulmonary edema, or sarcoidosis. A large amount of drugs have been incriminated, including those used in cardiovascular diseases (amiodarone, statins and angiotensin converting enzyme inhibitors), antibiotics (minocycline, nitrofurantoin), most of anticancer drugs (and especially chemotherapy and chest radiation), treatment of rheumatoid arthritis, as well as more recent drugs. A high index of suspicion is therefore required in any patient with infiltrative lung disease and the web-based tool www.pneumotox.com will help to list possible causative drugs. The following steps are necessary: history and timing of drug exposure, clinical and imaging pattern, exclusion of other causes of infiltrative lung disease, improvement following drug discontinuation. Rechallenge, dangerous, is not recommended.
