RESUMO
RATIONALE: Severe asthma is burdened by relevant socio-economic and clinical impact. Randomized controlled trials on Dupilumab showed efficacy and a good safety profile, but post-market studies are needed. OBJECTIVES: To evaluate the impact of Dupilumab on (i) the use of anti-asthmatic drugs, including oral corticosteroids (OCS), (ii) the rates of asthma exacerbation-related hospital admissions, and (iii) the healthcare costs in patients with asthma. METHODS: Data were retrieved from Healthcare Utilization database of Lombardy region (Italy). We compared healthcare resources use between the 6 months after Dupilumab initiation ("post-intervention period") and (i) the 6 months before Dupilumab initiation ("wash-out period") and (ii) the corresponding 6 months of the prior year ("pre-intervention period"). MAIN RESULTS: In a cohort of 176 patients, Dupilumab significantly reduced anti-asthmatic drugs use (including OCS and short-acting ß2-agonists, inhaled corticosteroids (ICS)/long-acting ß2-agonists and ICS alone) when comparing the "pre-intervention" to the "post-intervention" period. When considering hospital admissions, we observed a not statistically or marginally significant reduction between both periods before Dupilumab and the post-intervention period. Six-months discontinuation rate was 8%. Overall healthcare costs had a tenfold increase between the "pre-intervention" and "post-intervention" period, which was mainly led by the biologic drug cost. Conversely, expenditures connected to hospital admissions did not change. CONCLUSIONS: Our real-world investigation suggests that Dupilumab reduced anti-asthmatic drugs use, including OCS, in comparison to a corresponding period in the prior year. However, long-term healthcare sustainability remains an open issue.

BACKGROUND: Conventional transbronchial needle aspiration (c-TBNA) and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) are both valuable diagnostic techniques for the diagnosis of hilar/mediastinal lesions. Although a superiority of EBUS-TBNA over c-TBNA may be expected, evidence-based data on a direct comparison between these 2 procedures are still lacking. OBJECTIVES: We aimed to test the superiority of EBUS-TBNA over c-TBNA in a randomized trial and to evaluate the cost-effectiveness profile of a staged strategy, including c-TBNA as initial test followed by EBUS-TBNA, in case of inconclusive results at rapid on-site evaluation. METHODS: Eligible patients were randomized 1:1 to either the EBUS-TBNA or c-TBNA group. The primary endpoint was to test the superiority of EBUS-TBNA sensitivity over c-TBNA. The secondary endpoints included the sensitivity of the staged strategy, as well as costs and safety related to each procedure and to their sequential combination. RESULTS: A total of 253 patients were randomized to either EBUS-TBNA (n = 127) or c-TBNA (n = 126), and 31 patients of the c-TBNA group subsequently underwent EBUS-TBNA. The sensitivity of EBUS-TBNA was higher, but not significantly superior to that of c-TBNA (respectively. 92% [95% CI 87-97] and 82% [95% CI 75-90], p > 0.05). The sensitivity of the staged strategy was 94% (95% CI 89-98). No major adverse events occurred. CONCLUSIONS: EBUS-TBNA was the single best diagnostic tool, although not significantly superior to c-TBNA. Due to the favorable cost-effectiveness profile of their sequential combination, in selected scenarios with a high probability of success from the standard procedure, these should not be necessarily intended as competitive and the staged strategy could be considered in clinical practice.

OBJECTIVES: SSc is a clinically heterogeneous and generalized disease, characterized by thickness of the connective tissue of the skin and internal organs, such as the digestive tract, impairing gastrointestinal (GI) motility. Our aim is to evaluate retrospectively abnormalities of oesophageal motility, gastric emptying, oro-cecal transit time (OCTT) and small intestine bacterial overgrowth (SIBO) in a large cohort of SSc patients. METHODS: Ninety-nine SSc patients were included in the study. Forty-two patients underwent oesophageal conventional manometry, 45 performed a [(13)C]octanoic acid breath test to measure gastric emptying time and all 99 patients performed a lactulose breath test in order to evaluate OCTT and SIBO. Data were compared with healthy controls. RESULTS: In SSc patients, median lower oesophageal sphincter (LOS) pressure [14 mmHg (25th-75th; 8-19) vs 24 mmHg (19-28); P < 0.01] and median wave amplitude [30 mmHg (16-70) vs 72 mmHg (48-96); P < 0.01] were lower than in controls. Oesophageal involvement, defined as reduced LOS pressure and ineffective oesophageal motility pattern, was encountered in 70% of SSc patients. A delayed gastric emptying time was present in 38% of SSc patients: mean t½ was 141 ± 79 min vs 90 ± 40 min of controls (P < 0.01). Also, OCTT was significantly delayed in SSc: median OCTT was 160 min (25th-75th; 135-180) vs 105 min (25th-75th; 90-135) of controls (P < 0.01). SIBO was observed in 46% of SSc compared with 5% of controls (P < 0.01). CONCLUSION: GI involvement is very frequent in SSc patients. Oesophagus and small bowel are more frequently impaired, whereas delayed gastric emptying is less common.
