Red flags for clinical suspicion of eosinophilic granulomatosis with polyangiitis (EGPA).

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA), is a rare ANCA-associated systemic vasculitis. Its overlapping features with other vasculitic or eosinophilic diseases, and the wide and heterogeneous range of clinical manifestations, often result in a delay to diagnosis. OBJECTIVE: To identify red flags that raise a suspicion of EGPA to prompt diagnostic testing and to present an evidence-based clinical checklist tool for use in routine clinical practice. METHODS: Systematic literature review and expert consensus to identify a list of red flags based on clinical judgement. GRADE applied to generate a strength of recommendation for each red flag and to develop a checklist tool. RESULTS: 86 studies were included. 40 red flags were identified as relevant to raise a suspicion of EGPA and assessed by the experts as being clinically significant. Experts agreed that a diagnosis of EGPA should be considered in a patient aged ≥6 years with a blood eosinophil level >1000 cells/µL if untreated and >500 cells/µL if previously treated with any medication likely to have altered the blood eosinophil count. The presence of asthma and/or nasal polyposis should reinforce a suspicion of EGPA. Red flags of asthma, lung infiltrates, pericarditis, cardiomyopathy, polyneuropathy, biopsy with inflammatory eosinophilic infiltrates, palpable purpura, digital ischaemia and ANCA positivity, usually anti-myeloperoxidase, among others, were identified. CONCLUSION: The identification of a comprehensive set of red flags could be used to raise a suspicion of EGPA in patients with eosinophilia, providing clinicians with an evidence-based checklist tool that can be integrated into their practice.

Efectividad del tratamiento con ciprofloxacino durante 21 días en la primoinfección por pseudomonas aeruginosa en las bronquiectasias no fibrosis quística / Effectiveness of treatment with ciprofloxacin during 21 days in primoinfection by pseudomonas aeruginosa in the bronchiectasia not cystic fibrosis

Las bronquiectasias no debidas a fibrosis quística (FQ) constituyen la tercera patología inflamatoria crónica más frecuente de las vías respiratorias.La infección bronquial determina la progresión de la enfermedad, siendo la infección por Pseudomonas aeruginosa la que se asocia con peor pronóstico. Por este motivo, las guías de práctica clínica recomiendan la erradicación de P. aeruginosa en la infección primaria. Hasta el momento ningún estudio ha demostrado la utilidad real de esta pauta de tratamiento en el manejo de la infección bronquial inicial por Pseudomonas aeruginosa, por lo que el objetivo de este estudio es determinar la efectividad del tratamiento con Ciprofloxacino 750 mg cada 12 horas por vía oral durante 21 días en la erradicación de P. aeruginosa en pacientes con bronquiectasias no relacionadas con FQ.

Bronchiectasis not due to cystic fibrosis (CF) constitutes the third most frequent chronic inflammatory pathology of the airways. Bronchial infection determines the progression of the disease, being infection by Pseudomonas aeruginosa the one that is associated with the worst prognosis. For this reason, clinical practice guidelinesrecommend eradication of P. aeruginosa in primary infection. At the moment, any study has shown the real usefulness of this treatment regimen in the management of the initial bronchial infection by Pseudomonas aeruginosa, so the objective of this study is to determine the effectiveness of treatment with Ciprofloxacin 750 mg every 12 hours orally for 21 days in the eradication of P. aeruginosa in patients with non-CF bronchiectasis.

Efectividad de reslizumab en asma grave no controlada (AGNC) eosinofílica con poliposis nasal asociada / Effectiveness of reslizumab in severe uncontrolled asthma (AGNC) eosinophilic with associated nasal polyposis

In order to better characterize the profile of asthmatic patients who could benefit from monoclonal antibody treatments, the present study evaluated the effectiveness of reslizumab after one year of treatment in patients with severe uncontrolled eosinophilic asthma, distinguishing those with chronic rhinosinusitis. with associated nasal polyposis (RSCcNP). Reslizumab proved to be effective in this series of patients by reducing asthma exacerbations, improving lung function and asthma control, in addition to reducing the size and symptoms caused by nasal polyposis.

Con el fin de caracterizar mejor el perfil de pacientes asmáticos que podrían beneficiarse de tratamientos con anticuerpos monoclonales, en el presente estudio se evaluó la efectividad de reslizumab tras un año de tratamiento en pacientes con asma grave no controlada eosinofílica, distinguiendo aquellos que presentaban rinosinusitis crónica con poliposis nasal (RSCcPN) asociada. Reslizumab demostró ser efectivo en esta serie de pacientes al reducir las agudizaciones asmáticas, mejorar la función pulmonar y el control del asma, además de lograr disminuir el tamaño y sintomatología ocasionada por la poliposis nasal.
