Bronchiectasis patients may suffer from frequent infections which may result in poor clinical course and outcome. Our aim was to evaluate the relationship between ABO blood group and clinical course and microorganisms grown in sputum in non-CF bronchiectasis adult patients. Material and method: Bronchiectasis patients followed between January 2016 and October 2024, microorganisms grown in sputum culture results were retrospectively evaluated.Demographic, clinical and laboratory data were extracted from hospital files. Patients were divided into four groups as O, A, B and AB blood group and compared in terms of clinical course (hospitalization and intensive care unit stay, presence and number of exacerbations and emergency visits, mortality) and sputum culture results. Results: A total of 102patients (51 males and 51females, 50%each) were included to the study. In 26 cases there was P.aeriginosa growth in sputum and 6 cases it was colonised. 25 (25,5%) patients were followed in ICU and 19(19,3%) patients were died. In all blood types investigated;all paarmeters were similar except median number of emergency visits /year was higher in B blood type(p=0,047). Discussion and conclusion: In the study, no difference was found between the blood groups in terms of the exacerbations, mortality rate and lung functions also growth of bacterial species in the sputum of adult patients with non cystic fibrosis bronchiectasis. However, emergency admissions due to lower respiratory tract infection were higher in the B blood group which suggested that the risk of infection may be higher in the B group. But due to the small number of cases, it was concluded that multicenter studies were needed to investigate the relationship between blood group and sputum growth and clinical course in bronchiectasis. Bronchiectasis ABO blood type microorganism pseudomonas aeriginosa Introduction and aim ABO blood groups are classified according to the antigens found on the erythrocyte surface. These antigens can be found not only on erythrocytes but also on epithelial cells and mucosal surfaces and may facilitate some infections and prevent other.Recent studies have shown that there is a significant relationship between blood group and susceptibility to various infections (1-6). This issue has been popularized in numerous studies, especially during the COVID-19 pandemic, and it has been observed that there is an increased risk of infection in individuals with group A, while there is a relative protective effect in group O(7, 8)In addition, a relationship between Helicobacter pylori infection and blood group(1) A has been established. Bronchiectasis is a chronic and progressive disease characterized by irreversible dilatation of the bronchi associated with impaired mucociliary clearance, mucus accumulation and recurrent infections.Infections play a key role in the onset and progression of the disease. Permanent damage to the airways leads to impaired mucociliary clearance and, together with the accumulation of mucus, creates a favorable environment for microorganisms. As a consequence: patients may suffer from frequent infections which may trigger acute attacks of the disease and lead to further damage to the bronchi(9-12).On the other hand infections are important both for progression of the disease and mortality (13). In pediatric patients it was reported that Blood group B was highly associated with P. aeruginosa sepsis (14). On the other hand no association was found between ABO blood type gene polymorphism and the lung disease severity and the age of onset of P. aeruginosa infection (15), nor with ABO Blood Group type and pseudomonas colonisation in CF bronchiectasis (16). To our knowledge the relation between bacterial infections and ABO blood type was not investigated in non CF bronchiectasis patients. So we planned this study to evaluate whether there was a relationship between ABO blood group and clinical course and microorganisms grown in sputum in non CF bronchiectasis adult patients. Material and method: Between January 2016 and October 2024, patients with a diagnosis of bronchiectasis, known blood type and sputum culture results were retrospectively evaluated.Demographic and clinical data, inhaled corticosteroid use, ABO blood group, sputum culture result, exacerbation, hospitalization and intensive care unit stay, and mortality, if any, were recorded. Patients were divided into four groups as O, A, B and AB blood group and compared in terms of clinical course (hospitalization and intensive care unit stay, presence and number of exacerbations, mortality) and sputum culture results. Ethical Considerations: Ethical approval was obtained from the Clinical Research Ethics Committee of Ümraniye Training and Research Hospital (Approval Date: December 12, 2023; Approval Number: B.10.1.TKH.4.34.H.GP.0.01/454). Institutional permission was granted to access and utilize anonymized patient data from the hospital’s electronic medical records. All data were de-identified prior to analysis to ensure confidentiality. The study was conducted in accordance with the principles of the Declaration of Helsinki and applicable data protection regulations. Statistical Analysis: All statistical analyses were performed using IBM SPSS Statistics for MacOS, version 29.0 (IBM Corp., Armonk, NY, USA). Categorical variables were presented as frequencies and percentages, and continuous variables were expressed as median values with minimum and maximum ranges. The normality of data distribution was assessed using the Kolmogorov-Smirnov test. For comparisons between two groups, the Mann-Whitney U test was used for non-normally distributed data. For comparisons among more than two groups, the Kruskal-Wallis H test was applied. The Chi-square test or Fisher’s exact test was used for categorical variables. Logistic regression analysis was performed to identify independent risk factors associated with bacterial growth in sputum. A p-value of <0.05 was considered statistically significant. Results A total of 102 patients were included in the study, consisting of 51 males and 51 females (50% each). The median age was similar across blood groups. Pseudomonas aeruginosa growth in sputum was identified in 26 patients (25.5%), and colonization was observed in 6 patients. Comorbidities were present in 58 patients. A total of 41 patients were using nebulizers, a subset used BiPAP, and several were on long-term oxygen therapy (LTOT). ICU admission occurred in 25 patients, while 19 patients died during the follow-up period. When clinical and microbiological parameters were compared among blood groups (O, A, B, AB), no statistically significant differences were found in terms of sex distribution, age, comorbidities, lung function parameters (FEV1, FVC), use of noninvasive ventilation, LTOT, ICS use, hospitalization duration, ICU admission, exacerbation rate, or mortality. Likewise, the rates of bacterial growth in sputum including Pseudomonas aeruginosa , other gram-negative and gram-positive organisms were similar among the groups. The only statistically significant difference was found in the number of emergency department visits per year, which was higher in patients with blood group B (p = 0.047). The median values of white blood cells, neutrophils, lymphocytes, eosinophils, and platelet counts were also comparable across groups (table 1). Discussion In the study, no difference was found between the blood groups in terms of the number of exacerbations, mortality rate and lung functions also growth of pseudomonas and other bacterial species in the sputum of adult patients with non-cystic fibrosis bronchiectasis.However, emergency admissions due to lower respiratory tract infection were higher in the B blood group which suggested that the risk of infection may be higher in the B group. Previous studies have reported that the risk of urinary, upper respiratory tract, gastrointestinal system and skin infections and the risk of infection with E.Coli, Pseudomonas and Staphylococcus species are lower in the 0 blood group than in other blood groups (6). It was reported that blood type O was also associated with increased incidence of cholera, plague, tuberculosis infections, and mumps, whereas blood type A was associated with increased incidence of smallpox and Pseudomonas aeruginosa infection; blood type B is also associated with increased incidence of gonorrhea, tuberculosis, and Streptococcus pneumoniae , E. coli , and salmonella infections; and blood type AB is associated with increased incidence of smallpox and E. coli and salmonella infections(5). The association between ABO blood groups and infections is mainly explained by the following biological mechanisms: (6). 1. Microbial Adhesion and Mechanism of Cell Entry: Some bacteria and viruses can directly target ABO antigens and may establish infections via binding these antigens e.g. Norovirus, Helicobacter pylori and Plasmodium falciparum. 2. Neutralizing Effect of Natural Antibodies: Anti-A and/or anti-B antibodies in plasma may play a role in preventing infection by inhibiting the binding of some pathogens to host cells. (e.g. SARS-CoV-2). 3. Modulation of the Immune Response: Some studies suggest that group A patients show an exaggerrated inflammatory response during infections related to cytokine production, leukocyte activation and cellular immune response which may effect the clinical course e.g. COVID-19, influenza and systemic infections. 4. Effects on Microbiota and Mucosal Immunity: ABO antigens are present in mucosal secretions and this may alter the structural composition of the microbiota in gastrointestinal and respiratory tract mucosa. Bacterial growth in sputum in bronchiectasis leads to increased morbidity and mortality. Previous studies have reported that the development of lower respiratory tract infections and chronic bacterial colonization in patients with bronchiectasis are associated with more severe symptoms, poorer quality of life, more frequent exacerbations, more hospitalizations, more rapid loss of lung function and higher mortality risk, especially pseudomonas aeruginosa, which is the most common bacterium in bronchiectasis and has the worst prognosis (17-20). Infectious exacerbations of bronchiectasis especially with pseudomonas aeriginosa in bronchiectasis are associated with increased morbidity and loss of lung functions and poor clinical course (5, 17).In our study, the rate of pseudomonas infection was.25,5%. In a study conducted by.. Wang et al P. aeruginosa was isolated in19.8% (17). The higher rate in our study may be expalined with the selection of patients only with microorganism growth in sputum samples. Although the emergency service admission per year was more frequent in B blood type, functional parmeters, hospitalisation duration, ICU follow up and mortality were similar. This may be explained with similar exacerbation rate. We concluded that blood group type may not have any effect on clinical course and outcome of bronchiectasis patients but the risk of infection may be higher in the B group. However, due to the small number of cases, it was concluded that multicenter studies were needed to investigate the relationship between blood group and sputum growth and clinical course in bronchiectasis.

These antigens can be found not only on erythrocytes but also on epithelial cells and mucosal surfaces and may facilitate some infections and prevent other.Recent studies have shown that there is a significant relationship between blood group and susceptibility to various infections (1-6). \u0026nbsp;This issue has been popularized in numerous studies, especially during the COVID-19 pandemic, and it has been observed that there is an increased risk of infection in individuals with group A, while there is a relative protective effect in group O(7, 8)In addition, a relationship between Helicobacter pylori infection and blood group(1) A has been established.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eBronchiectasis is a chronic and progressive disease characterized by irreversible dilatation of the bronchi associated with impaired mucociliary clearance, mucus accumulation and recurrent infections.Infections play a key role in the onset and progression of the disease. Permanent damage to the airways leads to impaired mucociliary clearance and, together with the accumulation of mucus, creates a favorable environment for microorganisms. As a consequence: patients may suffer from frequent infections which may \u0026nbsp;trigger acute attacks of the disease and lead to further damage to the bronchi(9-12).On the other hand infections are important both for progression of the disease and mortality (13). In pediatric patients it was reported that Blood group B was highly associated with P. aeruginosa sepsis (14). On the other hand no association was found between ABO blood type gene polymorphism and the lung disease severity and \u0026nbsp;the age of onset of P. aeruginosa infection\u0026nbsp;(15), nor with \u0026nbsp;ABO Blood Group type and pseudomonas colonisation in CF bronchiectasis\u0026nbsp;(16). To our knowledge the relation between bacterial infections and ABO blood type was not investigated in non CF bronchiectasis patients. So we planned\u0026nbsp;this study \u0026nbsp;to evaluate whether there was a relationship between ABO blood group and clinical course and microorganisms grown in sputum in non CF bronchiectasis adult patients.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial and method:\u003c/strong\u003eBetween January 2016 and October 2024, patients with a diagnosis of bronchiectasis, known blood type and sputum culture results were retrospectively evaluated.Demographic and clinical data, inhaled corticosteroid use, ABO blood group, sputum culture result, exacerbation, hospitalization and intensive care unit stay, and mortality, if any, were recorded. Patients were divided into four groups as O, A, B and AB blood group and compared in terms of clinical course (hospitalization and intensive care unit stay, presence and number of exacerbations, mortality) and sputum culture results.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u0026nbsp;Ethical Considerations:\u003c/strong\u003e Ethical approval was obtained from the Clinical Research Ethics Committee of Ümraniye Training and Research Hospital (Approval Date: December 12, 2023; Approval Number: B.10.1.TKH.4.34.H.GP.0.01/454). Institutional permission was granted to access and utilize anonymized patient data from the hospital’s electronic medical records.

The study was conducted in accordance with the principles of the Declaration of Helsinki and applicable data protection regulations.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eStatistical Analysis:\u0026nbsp;\u003c/strong\u003eAll statistical analyses were performed using IBM SPSS Statistics for MacOS, version 29.0 (IBM Corp., Armonk, NY, USA). Categorical variables were presented as frequencies and percentages, and continuous variables were expressed as median values with minimum and maximum ranges.\u003c/p\u003e\n\u003cp\u003eThe normality of data distribution was assessed using the Kolmogorov-Smirnov test. For comparisons between two groups, the Mann-Whitney U test was used for non-normally distributed data. For comparisons among more than two groups, the Kruskal-Wallis H test was applied. The Chi-square test or Fisher’s exact test was used for categorical variables. Logistic regression analysis was performed to identify independent risk factors associated with bacterial growth in sputum.\u003c/p\u003e\n\u003cp\u003eA p-value of \u0026lt;0.05 was considered statistically significant.\u003c/p\u003e"},{"header":"Results","content":"\u003cp\u003eA total of 102 patients were included in the study, consisting of 51 males and 51 females (50% each). The median age was similar across blood groups. \u003cem\u003ePseudomonas aeruginosa\u003c/em\u003e growth in sputum was identified in 26 patients (25.5%), and colonization was observed in 6 patients. Comorbidities were present in 58 patients. A total of 41 patients were using nebulizers, a subset used BiPAP, and several were on long-term oxygen therapy (LTOT). ICU admission occurred in 25 patients, while 19 patients died during the follow-up period. When clinical and microbiological parameters were compared among blood groups (O, A, B, AB), no statistically significant differences were found in terms of sex distribution, age, comorbidities, lung function parameters (FEV1, FVC), use of noninvasive ventilation, LTOT, ICS use, hospitalization duration, ICU admission, exacerbation rate, or mortality. Likewise, the rates of bacterial growth in sputum including \u003cem\u003ePseudomonas aeruginosa\u003c/em\u003e, other gram-negative and gram-positive organisms were similar among the groups. The only statistically significant difference was found in the number of emergency department visits per year, which was higher in patients with blood group B (p\u0026thinsp;=\u0026thinsp;0.047). The median values of white blood cells, neutrophils, lymphocytes, eosinophils, and platelet counts were also comparable across groups (table 1).\u003c/p\u003e"},{"header":"Discussion","content":"\u003cp\u003eIn the study, no difference was found between the blood groups in terms of the number of exacerbations, mortality rate and lung functions also growth of pseudomonas and other bacterial species in the sputum of adult patients with \u0026nbsp; non-cystic fibrosis bronchiectasis.However, emergency admissions due to lower respiratory tract infection were higher in the B blood group which suggested that the risk of infection may be higher in the B group.\u003cstrong\u003e\u0026nbsp;\u003c/strong\u003ePrevious studies have reported that the risk of urinary, upper respiratory tract, gastrointestinal system and skin infections and the risk of infection with E.Coli, Pseudomonas and Staphylococcus species are lower in the 0 blood group than in other blood groups (6). It was reported that blood type O was also associated with increased incidence of cholera, plague, tuberculosis infections, and mumps, whereas blood type A was associated with increased incidence of smallpox and \u003cem\u003ePseudomonas aeruginosa\u003c/em\u003e infection; blood type B is also associated with increased incidence of gonorrhea, tuberculosis, and \u003cem\u003eStreptococcus pneumoniae\u003c/em\u003e, \u003cem\u003eE. coli\u003c/em\u003e, and salmonella infections; and blood type AB is associated with increased incidence of smallpox and \u003cem\u003eE. coli\u003c/em\u003e and salmonella infections(5).\u003c/p\u003e\n\u003cp\u003eThe association between ABO blood groups and infections is mainly explained by the following biological mechanisms: (6).\u003c/p\u003e\n\u003cp\u003e1. Microbial Adhesion and Mechanism of Cell Entry: Some bacteria and viruses can directly target ABO antigens and may establish infections via binding these antigens e.g. Norovirus, Helicobacter pylori \u0026nbsp;and Plasmodium falciparum.\u003c/p\u003e\n\u003cp\u003e2. Neutralizing Effect of Natural Antibodies: Anti-A and/or anti-B antibodies in \u0026nbsp;plasma may play a role in preventing infection by inhibiting the binding of some pathogens to host cells. (e.g. SARS-CoV-2).\u003c/p\u003e\n\u003cp\u003e3. Modulation of the Immune Response: \u0026nbsp;Some studies suggest that group A patients \u0026nbsp;show an exaggerrated inflammatory response during infections related to \u0026nbsp;cytokine production, leukocyte activation and cellular immune response which may effect the clinical course e.g. COVID-19, influenza and systemic infections.\u003c/p\u003e\n\u003cp\u003e4. Effects on Microbiota and Mucosal Immunity: ABO antigens are present in mucosal secretions and this may alter the structural composition of the microbiota in gastrointestinal and respiratory tract mucosa.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eBacterial growth in sputum in bronchiectasis leads to increased morbidity and mortality. Previous studies have reported that the development of lower respiratory tract infections and chronic bacterial colonization in patients with bronchiectasis are associated with more severe symptoms, poorer quality of life, more frequent exacerbations, more hospitalizations, more rapid loss of lung function and higher mortality risk, especially pseudomonas aeruginosa, which is the most common bacterium in bronchiectasis and has the worst prognosis (17-20).\u003c/p\u003e\n\u003cp\u003eInfectious exacerbations of bronchiectasis \u0026nbsp; especially with pseudomonas aeriginosa in bronchiectasis are associated with increased morbidity and loss of lung functions and poor clinical course (5, 17).In our study, the rate of pseudomonas infection was.25,5%. In a study conducted by.. Wang et al \u003cem\u003eP. aeruginosa\u003c/em\u003e was isolated in19.8% (17). The higher rate in our study may be expalined with the selection of patients only with microorganism growth in sputum samples. Although the emergency service admission per year was more frequent in B blood type, functional parmeters, hospitalisation duration, ICU follow up and mortality were similar. This may be explained with similar exacerbation rate.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eWe concluded that blood group type may not have any effect on clinical course and outcome of bronchiectasis patients but the risk of infection may be higher in the B group. However, due to the small number of cases, it was concluded that multicenter studies were needed to investigate the relationship between blood group and sputum growth and clinical course in

Bronchiectasis patients may suffer from frequent infections which may result in poor clinical course and outcome. Our aim was to evaluate the relationship between ABO blood group and clinical course and microorganisms grown in sputum in non-CF bronchiectasis adult patients.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial and method: \u003c/strong\u003eBronchiectasis patients followed between January 2016 and October 2024, microorganisms grown in sputum culture results were retrospectively evaluated.Demographic, clinical and laboratory data were extracted from hospital files. Patients were divided into four groups as O, A, B and AB blood group and compared in terms of clinical course (hospitalization and intensive care unit stay, presence and number of exacerbations and emergency visits, mortality) and sputum culture results.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults: \u003c/strong\u003eA total of 102patients (51 males and 51females, 50%each) were included to the study. In 26 cases there was P.aeriginosa growth in sputum and 6 cases it was colonised. 25 (25,5%) patients were followed in ICU and 19(19,3%) patients were died. In all blood types investigated;all paarmeters were similar except median number of emergency visits /year was higher in B blood type(p=0,047).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiscussion and conclusion: \u003c/strong\u003eIn the study, no difference was found between the blood groups in terms of the exacerbations, mortality rate and lung functions also growth of bacterial species in the sputum of adult patients with non cystic fibrosis bronchiectasis. However, emergency admissions due to lower respiratory tract infection were higher in the B blood group which suggested that the risk of infection may be higher in the B group. But due to the small number of cases, it was concluded that multicenter studies were needed to investigate the relationship between blood group and sputum growth and clinical course in bronchiectasis.\u003c/p\u003e","manuscriptTitle":"Association Between Blood Type Clinical Course and Sputum Microorganisms in Bronchiectasis","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-30 04:11:36","doi":"10.21203/rs.3.rs-7502427/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"57e3b939-8e0d-439b-b362-3ca99d79d62b","owner":[],"postedDate":"October 30th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2025-12-10T07:55:40+00:00","versionOfRecord":[],"versionCreatedAt":"2025-10-30 04:11:36","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7502427","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7502427","identity":"rs-7502427","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
