It is a complex condition with numerous different etiologies, co-morbidities, and a heterogeneous presentation. As we know, there is a lack of studies that describe the differences and compare the characteristics between focal and multifocal bronchiectasis. The aim of this study is to identify differences in clinical characteristics presentation, severity or distribution in focal and multifocal bronchiectasis, and prognostic implications. Methods: 126 patients with computed tomography (CT)-verified bronchiectasis were enrolled. Baseline characteristics that included age, sex, smoking history, and respiratory symptoms were recorded, with special attention paid to hemoptysis appearance, body mass index, and comorbidities. The type of bronchiectasis determined by CT scan and the modified Reiff scores indicating radiological severity were recorded. Patients were divided in two groups (I is focal and II is multifocal). Results: There were no statistically significant differences in age, smoking status, comorbidity, and BMI between the two groups. Multifocality was associated with a significantly higher proportion of females (p = 0.014), the rate of hemoptysis (p = 0.023), and the number of hospitalizations, but not of exacerbations and prevalence of immunodeficiency (p = 0.049). Significantly, a high number of subjects with multifocality had bronchiectasis of moderate severity, and post-infective and asthma-associated phenotypes were the dominant in this group. Unexpectedly, the cystic and varicose radiological phenotype (which need more time to develop) were more dominant in the focal group. The cylindrical phenotype was equally observed in the multifocal and focal groups. Conclusions: Our study suggests that multifocality is not related to age, number of exacerbations, or radiological phenotype, but it seems to be associated with the clinical post-infective phenotype, immunodeficiency, frequent hospitalizations, and severity. Thus, the presence of multifocal bronchiectasis may act as a biomarker of severity and poor outcomes in these patients.<\/jats:p>","DOI":"10.3390\/medicina60050795","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T10:26:36Z","timestamp":1715682396000},"page":"795","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Phenotype and Clinicoradiological Differences in Multifocal and Focal Bronchiectasis"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8529-8624","authenticated-orcid":false,"given":"Jelena","family":"Jankovic","sequence":"first","affiliation":[{"name":"Clinic for Pulmonology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"},{"name":"Medical Faculty, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandar","family":"Jandric","sequence":"additional","affiliation":[{"name":"Clinic for Pulmonology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0825-4748","authenticated-orcid":false,"given":"Natasa","family":"Djurdjevic","sequence":"additional","affiliation":[{"name":"Clinic for Pulmonology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"},{"name":"Medical Faculty, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2618-4176","authenticated-orcid":false,"given":"Dragan","family":"Vukosavljevic","sequence":"additional","affiliation":[{"name":"Clinic for Pulmonology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zlatan","family":"Bojic","sequence":"additional","affiliation":[{"name":"Clinic for Pulmonology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrej","family":"Zecevic","sequence":"additional","affiliation":[{"name":"Clinic for Pulmonology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1787-1438","authenticated-orcid":false,"given":"Mihailo","family":"Stjepanovic","sequence":"additional","affiliation":[{"name":"Clinic for Pulmonology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"},{"name":"Medical Faculty, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"180016","DOI":"10.1183\/16000617.0016-2018","article-title":"Bronchiectasis: A case-based approach to investigation and management","volume":"27","author":"Contarini","year":"2018","journal-title":"Eur.
