RESUMEN
We assessed the relationships between changes in lung compliance, lung volumes and dynamic hyperinflation in patients with emphysema who underwent bronchoscopic treatment with nitinol coils (coil treatment) (n=11) or received usual care (UC) (n=11). Compared with UC, coil treatment resulted in decreased dynamic lung compliance (CLdyn) (p=0.03) and increased endurance time (p=0.010). The change in CLdyn was associated with significant improvement in FEV1 and FVC, with reduction in residual volume and intrinsic positive end-expiratory pressure, and with increased inspiratory capacity at rest/and at exercise. The increase in end-expiratory lung volume (EELV) during exercise (EELVdyn-ch=EELVisotime EELVrest) demonstrated significant attenuation after coil treatment (p=0.02).

Articular manifestations should be screened before and during anti-IL-5/5R biologic treatment in severe asthma. Rigorous multidisciplinary team discussion should be carried out to assess the risk-benefit balance of withholding effective treatment. https://bit.ly/3vfPn4k.
RESUMEN
BACKGROUND: Hypersensitivity reactions (HSRs) to platinum salts (PS) and taxanes (TX) are a challenge to cancer management. Allergy evaluation based on skin tests (ST) and graded challenges can provide a diagnosis of an allergy to a suspected drug and indicate possible treatment with alternative same-class drugs. OBJECTIVE: This study aimed to estimate the negative predictive value of ST in the diagnosis of HSRs to TX and PS. METHODS: This multicenter study prospectively enrolled patients with a suspected HSR to PS and TX. ST were performed for chemotherapy, drugs of the same pharmacological class, and other agents (latex or cotreatments). For patients with negative ST, a graded challenge was performed by the cancer teams trained in allergy management. RESULTS: A total of 119 consecutive patients were included during a 6-year period. ST results were positive for 58% of the cohort: for TX in 7 patients and for PS in 62 patients. Other agents were responsible for 4.2% of cases. Skin cross-reactivity was 50% for TX and 30% for PS. A graded challenge was performed in 14 patients for TX and in 50 patients for PS. Negative predictive values (NPVs) for ST were 100% for TX and 92% for PS, with NPVs for individuals PS of 100% for cisplatin, 89% for oxaliplatin, and 87% for carboplatin. CONCLUSIONS: ST to PS or TX offered a high NPV, making allergy evaluation a key element in the management of patients with cancer. Graded challenges can be safely performed by oncology teams trained in anaphylaxis management.
