RESUMO

Background: The severe forms of influenza infection requiring intensive care unit (ICU) admission remain a medical challenge due to its high mortality. New H1N1 strains were hypothesized to increase mortality. The studies below represent a large series focusing on ICU-admitted influenza patients over the last decade with an emphasis on factors related to death. Methods: A retrospective study of patients admitted in ICU for influenza infection over the 2010-2019 period in Réunion Island (a French overseas territory) was conducted. Demographic data, underlying conditions, and therapeutic management were recorded. A univariate analysis was performed to assess factors related to ICU mortality. Results: Three hundred and fifty adult patients were analyzed. Overall mortality was 25.1%. Factors related to higher mortality were found to be patient age >65, cancer history, need for intubation, early intubation within 48 h after admission, invasive mechanical ventilation (MV), acute respiratory distress syndrome (ARDS), vaso-support drugs, extracorporal oxygenation by membrane (ECMO), dialysis, bacterial coinfection, leucopenia, anemia, and thrombopenia. History of asthma and oseltamivir therapy were correlated with a lower mortality. H1N1 did not impact mortality. Conclusion: Patient's underlying conditions influence hospital admission and secondary ICU admission but were not found to impact ICU mortality except in patients age >65, history of cancer, and bacterial coinfections. Pulmonary involvement was often present, required MV, and often evolved toward ARDS. ICU mortality was strongly related to ARDS severity. We recommend rapid ICU admission of patients with influenza-related pneumonia, management of bacterial coinfection, and early administration of oseltamivir.

RESUMO

BACKGROUND: Metastatic spread to the tracheobronchial tree from other than bronchopulmonary tumors is a common clinical problem. However, malignant melanoma, a highly metastatic potential tumor, is rarely metastasing in the airways. Therefore little is known about survival of patients with endobronchial metastasis from melanoma. OBJECTIVES: The aim of our study was to assess survival of patients with endobronchial metastasis of melanomas according to clinical and radiological features, to determine any possible factor affecting survival. METHODS: This retrospective study included 19 patients who underwent a bronchoscopy from 11 different hospitals. Data about patients' demographics, symptoms, radiographic, endoscopic findings and treatment were investigated to evaluate any possible impact on survival. RESULTS: Endobronchial metastases occurred at a median of 48 months (range 0-120) following the diagnosis of the primary tumor. About 73.7% of patients had other proven metastases when the endobronchial involvement was diagnosed. Symptoms are not specific as well as radiological features. Median overall survival of the studied population was 6 months (range 1-46). Factors of poor survival were multiple metastatic sites (P = 0.019), pleural (P = 0.0014) and soft tissue metastasis (P = 0.024). Different treatment modalities applied in our patients showed no effect on survival. CONCLUSION: Patients with endobronchial metastasis have overall poor survival, affected by multiple organ involvement, the presence of pleural and soft tissue disease, while no impact on survival has been shown by any treatment applied.

RESUMO

BACKGROUND: The French College of General Hospital Respiratory Physicians conducted two studies that consecutively included all patients followed in participating general hospitals for primary small cell (SCLC) or non-small cell (NSCLC) lung cancer diagnosed in 2000 and 2010. These studies allow descriptive statistics and outcome assessment for SCLC and NSCLC separately and comparison over a 10-year period. METHODS: A standardised form was completed for each patient at inclusion. Then, vital status was collected. RESULTS: In 2000 and 2010, 948 (15.5% female) and 968 (23.3%) SCLC patients, mainly heavy active- or former-smoker seniors, participated in these studies. One-year survival rate was 35.8% for SCLC vs. 44.8% for NSCLC in 2010 and 33.1% for SCLC in 2000. In 2010, in reference to stage 0-IIB (4.1% of SCLCs), the hazard ratio was 0.92 [95% confidence interval (CI): 0.6-1.5; P=0.76], 1.8 (95% CI: 1.1-2.8; P=0.019), and 3.4 (95% CI: 2.2-5.3; P<0.001) for stage IIIA (10.2%), IIIB (14.5%), and IV (71.2%). Positron emission tomography (PET)-scan use, which has increased in 10 years, was frequent in patients with limited disease. CONCLUSIONS: One-year survival in SCLC patients was poor in 2010 and dependent of SCLC stage. TNM classification reintroduction and new diagnostic techniques (e.g., PET-scan) should allow lung oncologists to tailor treatment based on disease stage at diagnosis.

RESUMO

Hypereosinophilic asthma (HEA) is considered as a specific severe asthma phenotype. Whether eosinophils have a link with airway remodeling characterized by pathological (thickening of the basement membrane), functional (persistent airflow impairment and decline in lung function) and imaging features (increase airway wall thickness at CT scan) is still debated. In a one year prospective cohort of 142 severe asthma patients (according to IMI), 14 persistent HEA patients (defined by a persistent blood eosinophilia >500/mm(3) at two consecutive visits) were identified and compared with ten patients without any blood eosinophilia during the follow-up period (NEA, blood eosinophilia always <500/mm(3)). Airflow and lung volumes were recorded. Bronchial biopsies obtained at enrollment were stained for eosinophils (EG2) and basement membrane thickness (BM) was quantified. Imaging by CT scan acquisition was standardized and bronchial abnormalities quantified. ACQ score and exacerbations were prospectively recorded. HEA was not associated with preeminent features of airway remodeling assessed by airflow impairment (Best ever FEV1 values 97% ± 20 in HEA vs. 80 ± 24% in NEA, p = 0.020), decline of FEV1 (FEV1 Decline 40 ± 235 ml/y in HEA vs. 19 ± 40 ml/y in NEA, P = 0.319), submucosal abnormalities (BM thickness 7.80 ± 2.66 µm in HEA vs. 6.84 ± 2.59 in NEA, p = 0.37) and airway wall thickening at CT-scan (0.250 ± 0.036 mm vs. 0.261 ± 0.043, p = 0.92). Eosinophils blood count was inversely correlated with semiquantitative imaging score (rho -0.373, p = 0.039). Smoking history and positive skin prick tests were independent risk factors for increased BM thickening. Outcomes were similar in both populations (Control and exacerbations). Persistent HEA is not associated with evidences of airway remodeling.

RESUMO

Phalanx bone metastasis as the initial presenting sign of lung cancer is a rare presentation. Lung cancer is known to metastasize to the bone, but rarely to the fingers. A 61-year-old male smoker presented with pain in the left ring finger. Severe pain discouraged the patient from using his left hand. An X-ray of the left hand showed a lytic bone lesion. The patient was treated with finger radiotherapy. Analgesics were no longer needed and the patient was able to reuse his left hand in his everyday life. Palliative radiotherapy relieved our patient and improved his quality of life.

RESUMO

BACKGROUND: Cross-sectional severe asthma cluster analysis identified different phenotypes. We tested the hypothesis that these clusters will follow different courses. OBJECTIVE: We aimed to identify which asthma outcomes are specific and coherently associated with these different phenotypes in a prospective longitudinal cohort. METHODS: In a longitudinal cohort of 112 patients with severe asthma, the 5 Severe Asthma Research Program (SARP) clusters were identified by means of algorithm application. Because patients of the present cohort all had severe asthma compared with the SARP cohort, homemade clusters were identified and also tested. At the subsequent visit, we investigated several outcomes related to asthma control at 1 year (6-item Asthma Control Questionnaire [ACQ-6], lung function, and medication requirement) and then recorded the 3-year exacerbations rate and time to first exacerbation. RESULTS: The SARP algorithm discriminated the 5 clusters at entry for age, asthma duration, lung function, blood eosinophil measurement, ACQ-6 scores, and diabetes comorbidity. Four homemade clusters were mostly segregated by best ever achieved FEV1 values and discriminated the groups by a few clinical characteristics. Nonetheless, all these clusters shared similar asthma outcomes related to asthma control as follows. The ACQ-6 score did not change in any cluster. Exacerbation rate and time to first exacerbation were similar, as were treatment requirements. CONCLUSION: Severe asthma phenotypes identified by using a previously reported cluster analysis or newly homemade clusters do not behave differently concerning asthma control-related outcomes, which are used to assess the response to innovative therapies. This study demonstrates a potential limitation of the cluster analysis approach in the field of severe asthma.

RESUMO

BACKGROUND: Asthma-like symptoms are frequent in overweight and obesity, but the mechanism is unclear when airway hyperresponsiveness (AHR) is lacking. In this study, we focused on obese women with a clinical suspicion of asthma but negative methacholine challenge and tested distal airway hyperreactivity, explored by Forced Vital Capacity dose-response slope (FVC DRS). OBJECTIVE: To question AHR at the distal airway level in obese women. METHODS: A total of 293 symptomatic obese and nonobese women free of treatment were investigated. Methacholine challenge tests were undertaken, and patients were divided according to their results to the test. In hyperreactive and nonhyperreactive patients and in our total population, correlations, regression analyses, and analyses of covariance were performed to compare distal airway hyperreactivity in three groups of body mass index (BMI). RESULTS: After adjusting for age and baseline respiratory values, the relationship between FVC and FEV1 (forced expiratory volume in one second) DRS was influenced by BMI, with a lower slope in obese than overweight and normal patients in our total population (P = 0.008) and in our nonhyperreactive one (P = 0.028). CONCLUSION: Distal airway hyperresponsiveness was observed in symptomatic wheezing obese women negative to methacholine challenge.

RESUMO

BACKGROUND: The clinical manifestations of bronchial remodeling in asthma and the potential impact of this process on lung function remain unclear. We aimed to determine whether the presence of pathologic features of airway remodeling in patients with asthma was associated with steroid responsiveness in the short term. METHODS: Sixty-three consecutive patients with severe asthma with chronic airflow impairment (post-bronchodilator FEV(1) < 80% predicted values) were recruited, clinically characterized, and had an initial bronchoscopy where endobronchial biopsy and BAL were performed. BAL cellular content was reported and reticular basement membrane (RBM) thickness was measured by validated repeated measures. Patients were then treated with 1 mg/kg/d of methyl prednisone, directly administered IV, for 10 days. A threshold of 15% FEV(1) improvement was used to discriminate responsive (group 1) and refractory patients (group 2). RESULTS: Thirty-eight patients had a steroid responsiveness > 15% (group 1) and a thinner RBM at the biopsy level (5.78 ± 2.0 µm vs 7.60 ± 2.2 µm; P = .001) compared with nonsteroid responsive group 2 patients as defined. The best predictors for being unresponsive were no long-term treatment with oral steroids and increased RBM thickness. The associated receiver operating characteristic curve indicated that RBM thickness could predict steroid responsiveness below 15% with an area under the curve of 0.747 (P = .0002) at a threshold of 7 µm. CONCLUSIONS: Features of airway remodeling are associated with limited short-term steroid responsiveness in severe asthma.

RESUMO

Smoking associated COPD progression is likely to be directly linked to differential injury and repair dynamics in small airways (SA). Although IL8 is a well-accepted marker for injured airway epithelium, Clara cells [the predominant proliferating cells in SA] and SCGB1A1 protein [their major secretory product] have only recently emerged as potential SA repair markers. We therefore postulate that the SCGB1A1/IL8 ratio in the airways of smokers would be inversely associated with physiological, radiological and clinical measures of COPD. A cross-sectional cohort of 28 smokers undergoing surgery for peripheral nodule was recruited (24M/4F, age 61 +/- 11 y, FEV1s 76 +/- 20%, smoking 40 +/- 12 p.y). SCGB1A1 and IL8 were measured by ELISA in the induced sputum (IS) 3 to 5 days prior to surgery as well as by immunohistochemistry from lung tissue (also assessed morphometrically) obtained distant to the cancer surgery site. COPD was assessed using standard clinical, functional and radiological parameters. Log-transformed IS-SCGB1A1 was linearly correlated with SCGB1A1-positive epithelial cells detected via immunohistochemistry (r = .533, p = .001), while IS-IL8 was positively related to SA infiltrating neutrophils (Elastase-positive cells). There was a striking negative correlation between IS-SCGB1A1/IL8 levels and whole airway thickness [SA < 2 mm] at morphometry (r = -0.83, p < 0.0001). IS-SCGB1A1/IL8 levels were also inversely associated with nitrogen slope [r = -0.52, p < 0.001] and HRCT SA score [r = -0.51, p < 0.001]. In a multivariate analysis the IS-SCGB1A1/IL8 ratio was a stronger predictor than both the physiological and radiological measures of SA disease assessed. The SCGB1A1/IL8 ratio measured in sputum is a potentially valuable biomarker for non-invasive assessment of SA remodelling in smokers.

RESUMO

BACKGROUND: Solitary endobronchial papillomas (SEP) are rare tumors and most of them are described by case report. A misdiagnosis is common with viral related papillomas. A histopathological classification has recently permitted a major advancement in the understanding of the disease. CASE PRESENTATION: We report a case of a mixed bronchial papilloma with an unusual endoscopic presentation. The literature was extensively reviewed to ascertain the unusual characteristics of the current case. A 39-year of age male was referred to our institution for the investigation of a slight hemoptysis. Routine examination was normal. A fibroscopy revealed an unusual feature of the right main bronchus. The lesion was a plane, non-bleeding, non-glistering sub-mucosal proliferation. No enhanced coloration was noticed. Biopsies revealed a mixed solitary bronchial papilloma. In situ HPV hybridization was negative. Endoscopic treatment (electrocautery) was effective with no relapse. CONCLUSION: This lesion contrasts with the data of the literature where papilloma were described as wart-like lesions or cauliflower tumors, with symptoms generally related to bronchial obstruction. We advise chest physicians to be cautious with unusually small swollen lesions of the bronchi that may reveal a solitary bronchial papilloma. Endoscopic imaging can significantly contribute to the difficult diagnosis of SEP by pulmonary physicians and endoscopists.

RESUMO

BACKGROUND: Most inoperable patients with esophageal-advanced cancer (EGC) have a poor prognosis. Esophageal stenting, as part of a palliative therapy management has dramatically improved the quality of live of EGC patients. Airway stenting is generally proposed in case of esophageal stent complication, with a high failure rate. The study was conducted to assess the efficacy and safety of scheduled and non-scheduled airway stenting in case of indicated esophageal stenting for EGC. METHODS AND FINDINGS: The study is an observational study conducted in pulmonary and gastroenterology endoscopy units. Consecutive patients with EGC were referred to endoscopy units. We analyzed the outcome of airway stenting in patients with esophageal stent indication admitted in emergency or with a scheduled intervention. Forty-four patients (58+/-\-8 years of age) with esophageal stenting indication were investigated. Seven patients (group 1) were admitted in emergency due to esophageal stent complication in the airway (4 fistulas, 3 cases with malignant infiltration and compression). Airway stenting failed for 5 patients. Thirty-seven remaining patients had a scheduled stenting procedure (group 2): stent was inserted for 13 patients with tracheal or bronchial malignant infiltration, 12 patients with fistulas, and 12 patients with airway extrinsic compression (preventive indication). Stenting the airway was well tolerated. Life-threatening complications were related to group 1. Overall mean survival was 26+/-10 weeks and was significantly shorter in group 1 (6+/-7.6 weeks) than in group 2 (28+/-11 weeks), p<0.001). Scheduled double stenting significantly improved symptoms (95% at day 7) with a low complication rate (13%), and achieved a specific cancer treatment (84%) in most cases. CONCLUSION: Stenting the airway should always be considered in case of esophageal stent indication. A multidisciplinary approach with initial airway evaluation improved prognosis and decreased airways complications related to esophageal stent. Emergency procedures were rarely efficient in our experience.

RESUMO

BACKGROUND: An outbreak of chikungunya virus infection occurred on Reunion Island during the period 2005-2006. Persistent arthralgia after chikungunya virus infection has been reported, but few studies have treated this aspect of the disease. METHODS: Adult patients with laboratory-confirmed acute chikungunya virus infection who were referred to Groupe Hospitalier Sud Reunion during the period 2005-2006 were asked to participate in the study. Patients were assessed a mean of 18 months after acute disease occurred. Assessment consisted of answering questions on a standard form, undergoing a medical examination, and being tested for the presence of IgM antibodies to chikungunya virus. RESULTS: Eighty-eight patients (mean age, 58.3 years; male-to-female ratio, 1.1:1.0) were included in this study. Fifty-eight patients (65.9%) had been hospitalized for acute chikungunya virus infection, and a history of arthralgia before chikungunya virus infection was reported by 39 patients (44%). Fifty-six patients (63.6%) reported persistent arthralgia related to chikungunya virus infection, and in almost one-half of the patients, the joint pain had a negative impact on everyday activities. Arthralgia was polyarticular in all cases, and pain was continuous in 31 patients (55.4%). Overall, 35 patients (39.7%) had test results positive for IgM antibodies to chikungunya virus. CONCLUSIONS: Persistent and disabling arthralgia was a frequent concern in this cohort of patients who had experienced severe chikungunya virus infection approximately 18 months earlier. Further studies are needed to evaluate the prevalence of persistent arthralgia in the general population to determine the real burden of the disease.

RESUMO

OBJECTIVE: Analysis of risk factors associated with severity in patients with confirmed leptospirosis. DESIGN AND SETTING: Retrospective study in 147 leptospirosis-confirmed patients at two tertiary nonteaching hospital in Reunion Island. PATIENTS: 138 men and 9 women, aged 36+/-14 years, 80 in the ICU and 67 in medical wards. MEASUREMENTS AND RESULTS: We collected demographic, clinical, biological, and radiographic data and performed univariate and multivariate analysis to examine risk factors associated with admission in ICU and mortality. Pulmonary forms were more frequent (85%) than in previous reports, with 85 cases (65.3%) on abnormal chest radiography. Among the 38 patients who underwent bronchoalveolar lavage at admission 31 (81.5%) had alveolar hemorrhage. Independent factors related to ICU admission were: age over 46[Symbol: see text]years (OR 3.02), creatinine higher than 200[Symbol: see text]mumol/l (6.69), shock (13.87), and acute respiratory failure (20.69). Mortality was 12.9%. The only factor independently related to mortality was need for mechanical ventilation (OR 20.94). Icterohemorrhagiae serogroup was found in 62 cases (42.8%) but was not related to death. CONCLUSIONS: Pulmonary involvement is a major feature in leptospirosis disease but is not associated with poor outcome. Identification of clinical and laboratory findings on admission may help to better characterize severe cases.

RESUMO

BACKGROUND: Reticular basement membrane (RBM) thickness is considered a hallmark for airway remodeling in airway diseases such as asthma. It is still unclear whether this measurement could be associated with disease severity or apply to chronic obstructive pulmonary disease (COPD). A wide range of results, at baseline or after therapeutic intervention, have been reported using different measurement methods. OBJECTIVE: To determine whether increased RBM thickness could be associated specifically with severe asthma and in COPD in large samples. METHODS: We blindly measured RBM thickness in endobronchial biopsies from 50 patients with severe asthma (mean age, 53 years; FEV(1) 66% predicted, inhaled steroids > or =1500 microg and 20 mg daily dose of oral corticosteroids, lifelong nonsmokers), 50 untreated patients with mild asthma (mean age, 33 years; FEV(1) 93%pred, lifelong nonsmokers), 50 patients with COPD (mean age, 57 years; FEV(1) 53%pred, all current smokers), and 18 control subjects using 2 different validated quantitative and computer-assisted methods (repeated multiple point-to-point vs area by length ratio). RESULTS: Reticular basement membrane thickness was higher in severe asthma compared with mild asthma and COPD (P = .0053). On the basis of receiver operating characteristic curves, RBM thickness was effective in differentiating severe asthma from other groups (sensitivity and specificity, 98% and 95%, respectively, above a threshold of 5 microm vs control, 70% and 75% at 7 microm vs mild, 83% and 68% at 6 microm vs COPD). CONCLUSION: Increased RBM thickness was specifically associated with severe asthma, whereas surprisingly, COPD and mild asthma had similar remodeling features. CLINICAL IMPLICATIONS: Reticular basement membrane thickness can be considered a hallmark of severe asthma.

RESUMO

BACKGROUND: Chikungunya is a reemerging disease. In 2005-2006, a severe outbreak occurred on Reunion Island in the southwestern part of the Indian Ocean. Other islands in this area were affected during the same period. METHODS: Adult patients with acute chikungunya (defined as onset of fever and/or polyarthralgia in the 5 days preceding consultation) and laboratory-confirmed chikungunya who were referred to Groupe Hospitalier Sud Reunion during the period from March 2005 through April 2006 were included in this retrospective study. Their clinical and laboratory features are reported. RESULTS: Laboratory-confirmed acute chikungunya was documented in 157 patients. The mean age of patients was 57.9 years, and the ratio of male to female patients was 1.24 : 1. Sixty percent of patients had at least 1 comorbidity. Ninety-seven patients (61.8%) were hospitalized, and 60 (38.2%) were treated as outpatients. Five fatalities were reported. One hundred fifty-one patients (96.1%) experienced polyarthralgia, and 129 (89%) experienced fever. Gastrointestinal symptoms were reported by 74 patients (47.1%), and skin rash was reported by 63 (40.1%). Hemorrhagic signs were rare. Lymphopenia and hypocalcemia were the prominent laboratory findings. Severe thrombocytopenia was rarely observed. CONCLUSIONS: Chikungunya virus can be responsible for explosive outbreaks of disease. Polyarthralgia and fever are the 2 main clinical features. In this era of travel and globalization, chikungunya should be considered in the differential diagnosis of febrile polyarthralgia with an abrupt onset.

RESUMO

Burkholderia pseudomallei, the causative agent of melioidosis, is endemic in Southeast Asia and Northern Australia but is a rare pathogen in other parts of the world. No human case of melioidosis has been reported in Madagascar until now. We describe a case of pulmonary melioidosis probably acquired in Madagascar.

RESUMO

Chikungunya is a viral disease transmitted by a mosquito of the genus Aedes. It is currently epidemic on Reunion Island, in the Indian Ocean. It is essentially characterized by an influenza syndrome but associated with polyarthralgia and an eruption. The disabling and chronic nature of the arthralgia is the most remarkable clinical aspect of chikungunya infection. Severe and unusual forms have appeared, not previously described in the literature. These forms must be studied to determine whether there is a direct relation between the chikungunya virus and the severity factors. Treatment is solely symptomatic, combining analgesic and/or antiinflammatory agents. There is no vaccine. The epidemic is not limited to Reunion: cases of chikungunya have also been reported in neighboring islands (Maurice, Seychelles, and Madagascar). Travelers planning to visit the region should be counseled.

RESUMO

OBJECTIVES: There has recently been great interest in the possible relationship between air travel and venous thromboembolism (VTE). Based on a case-control survey, we measured the frequency of VTE, associated risk factors (RFs), and factors influencing the onset of pulmonary embolism (PE) or deep vein thrombosis (DVT). METHODS: The study was conducted over 1 yr. A questionnaire was sent to physicians. Patients with a diagnosis of VTE were included, provided they had traveled from France to Reunion Island. RESULTS: Over 46 cases, 33 patients showed DVT and 13 PE. RFs for VTE were present in 38 patients (82%). On comparing RFs between study and control groups, we found no differences in age, gender, alcohol, sleep-inducing drug consumption, seat allocation, or estroprogestative treatment. RFs were significantly higher in the VTE group at p < 0.005: history of previous VTE (OR 63.3), recent trauma (OR 13.6), presence of varicose veins (OR 10), obesity (OR 9.6), immobility during flight (9.3), and cardiac disease (OR 8.9). For patients with DVT or PE, no differences were observed in comparing RFs. The PE group was older and mortality occurred only in this group. The number of displacements during flight (p < 0.009) and complete immobility (p < 0.001) were strongly related with onset of PE. Delay of symptoms was less than 24 h in 69% of PE cases compared with 21% of DVT cases (p < 0.004). CONCLUSION: Long-duration air travel VTE is associated with other underlying thromboembolic RFs. Low mobility during flight is a striking modifiable RF of developing PE. Travelers with RFs for VTE should be advised to increase their mobility.

RESUMO

INTRODUCTION: The aim of this study was to assess the efficacy of leucotrien- antagonists in aspirin-intolerant asthma (AIA). The severity of asthma was evaluated according to GINA guidelines. On each consultation, the patients filled-in a simplified self-assessment questionnaire on rhinitis and quality of life (QOL). METHODS: Montelukast was administered during the inclusion visit. Patients' general state of health was assessed, FEV1 and MMEF25-75 were measured and the QOL and rhinitis scores and therapeutic impact were analysed at 3 and 6 months. RESULTS: Sixteen patients were included. FEV1 was initially recorded at 62% +/- 23 of theoretical values and then improved to 73% +/- 26.8 (p<0.002), and 77.2% +/- 17. Initial rhinitis score was 13 +/- 3.7 then 9 +/-5 (p<0.006) and 5.7 +/- 3.5 (p<0.03). Oral corticosteroids were required in 12 patients (8.5 +/- 5.6 mg). This dose was tapered to 3.4 +/- 6.4 mg (p<0.04) and 2.1 +/- 4.4 mg and stopped in 8 patients. The initial QOL score was of 4.36 +/- 1.4 and improved to 5.87 +/- 1.06 (p<0.002), and to 5.90 +/- 1.12. DISCUSSION: Aspirin-induced asthma is a challenging issue. Rhinitis is a major feature of discomfort. Following montelukast administration, we noted an improvement in the QOL and rhinitis subjective parameters, and an objective improvement in spirometrical measurements and in the doses of oral corticosteroids. CONCLUSION: Early recognition of these asthmatic patients is required in order to optimise their management. Administration of montelukast could be envisaged as unofficial first-line therapy in these patients combined with the recommended treatments.
