Abstract
Most physicians in general, and family physicians in particular, are familiar with certain parameters when ordering a hematological study, such as hemoglobin (including hematocrit and its features), leukocytes (including lymphocytes) and platelets. Nevertheless, there are two values that we use to overlook which are eosinophils and basophils. Specifically, eosinophils have a tendency to increase with allergic pathology. This article focuses on this type of cells, helping to interpret the values obtained and highlighting their importance in two of the most frequent respiratory pathologies in primary care: asthma and COPD. In addition to observing how the increase or normality of these parameters condition the diagnosis, phenotype and even the treatment.

Expert Rev Respir Med 2023; 17:675-690. [PMID: 37647343 DOI: 10.1080/17476348.2023.2254234] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 08/24/2023] [Accepted: 08/29/2023] [Indexed: 09/01/2023]
Abstract
INTRODUCTION Although rare, pediatric severe therapy-resistant asthma (STRA) is a highly heterogeneous, resource-demanding disease that differs significantly from severe adult asthma and whose pathogenesis is still poorly understood. AREAS COVERED This review summarizes the latest 10 years of English-written studies defining pediatric STRA endotypes using lung-specific techniques such as bronchoalveolar lavage and endobronchial biopsy. Results of the studies and limits on the field are discussed, together with some future perspectives. EXPERT OPINION Over the years, it has become increasingly clear that 'one size does not fit all" in asthma. However, "Does an extremely tailored size fit more than one?'. Only using multicentric, longitudinal pediatric studies, will we be able to answer. Three issues could be particularly critical for future research. First, to provide, if existing, a distinction between prepuberal STRA and puberal STRA endotypes to understand the transition from pediatric to adult STRA and to design effective, tailored therapies in adolescents, usually suffering from poorer asthma control. Second, design early treatments for pediatric airway remodeling to preserve lifelong good lung function. Finally, to better characterize inflammation before and during biological therapies, to provide clues on whether to stop or change treatments.

Ther Adv Respir Dis 2023; 17:17534666231213637. [PMID: 38069568 PMCID: PMC10710755 DOI: 10.1177/17534666231213637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 10/23/2023] [Indexed: 12/18/2023] Open
Abstract
At present, medications containing inhaled corticosteroids (ICS-containing) are the keystones of asthma treatment. The majority of asthmatic children can significantly improve clinical outcomes with little worsening by standardized inhaled glucocorticoid treatment, but there is still a small proportion of children who are unable to achieve good symptom control even after the maximum standardized treatment, known as 'children with difficult-to-treat asthma (DA)'. The high heterogeneity of DA makes therapy challenging and expensive, which poses a serious risk to children's health and makes it extremely difficult for clinical physicians to accurately identify and treat children with DA. This article reviews the definition, evaluation, and treatment of this asthma in order to provide a reference for optimal clinical decision-making.
