Abstract
Background Bronchiectasis is a disease with predominantly neutrophilic inflammation. As a readily available biomarker, there is little evidence to support the use of blood neutrophil-to-lymphocyte ratio (NLR) to predict bronchiectasis exacerbation severe enough to warrant hospitalization. Methods A registry-based retrospective cohort study was conducted at a in Hong Kong. Chinese patients with non-cystic fibrosis (CF) bronchiectasis were retrospectively reviewed and subsequently followed up to investigate the association of NLR and the need for hospitalization for bronchiectasis exacerbation. Data on the NLR for patients in a clinically stable state in 2018 were collected and patients followed up from 1 January 2019 to 31 December 2022. The primary outcome was the need for hospitalization due to bronchiectasis exacerbation over the next 4 years. Results We reviewed 473 Chinese patients with non-CF bronchiectasis, of whom 94 required hospitalization for bronchiectasis exacerbation during the 4-year follow-up period. Multi-variable logistic regression adjusted for E-FACED score (Exacerbation, Forced expiratory volume in 1 s (FEV1), Age, Chronic colonization, Extension, and Dyspnea score), gender, age, smoking status, and presence of co-existing chronic obstructive pulmonary disease (COPD) was conducted to compare patients with highest and lowest quartile NLR. Results revealed that those with NLR at the highest quartile were at increased risk of hospitalization for bronchiectasis exacerbation with an adjusted odds ratio (aOR) of 2.02 (95% confidence interval = 1.00-4.12, p = 0.05). Conclusion Blood NLR may serve as a marker to predict the need for hospitalization due to bronchiectasis exacerbation.

Abstract
Our study aimed to enhance understanding of nasal polyp pathophysiology by reviewing the data for variations of NLR values between patients with nasal polyp and healthy controls. We searched Web of Science, PubMed, ProQuest, and Scopus up to 2 April 2023. The search strategy was not limited to any specific language. Twelve studies were included in our study. Of them, ten studies, involving 898 nasal polyp patients and 590 control patients, were included in the meta-analysis. The NLR levels in nasal polyp patients were statistically greater than in the control group (SMD = 0.56; 95%CI 0.04-1.08, P = 0.036). Subgroup analysis based on study design yielded that patients with nasal polyp exhibited significantly higher NLR levels than healthy controls in retrospective studies (SMD = 0.83; 95%CI 0.30-1.35, P = 0.002) but not in prospective studies (SMD = 0.10; 95%CI = -1.03 to 1.23, P = 0.85). Also, we found that the NLR levels in nasal polyp patients were significantly higher than healthy controls in high-quality studies (SMD = 1.00; 95%CI 0.38-1.62, P = 0.002) but not in low-quality studies (SMD = 0.11; 95%CI = -0.69 to 0.91, P = 0.79). A total of 312 patients with recurrence and 550 patients without recurrence were included in the study. The combined results revealed that NLR levels in nasal polyp recurrence patients were significantly higher than those of the nasal polyp without recurrence group (SMD = 0.06, 95% CI 0.39-0.81, P = 0.000). These results showed the relationship between the NLR in nasal polyps and can help medical doctors to predict the recurrence of the disease in such patients.

Abstract
OBJECTIVE The objective of this study is to analyze the risk factors associated with bronchiectasis combined with non-tuberculous mycobacteria pulmonary disease(NTM-PD) and provide a basis for more effective prevention and treatment strategies. METHODS The study subjects for this manuscript were patients with bronchiectasis who were admitted to the infection department between January 2021 and June 2023.There were 34 patients with NTM-PD in the observation group, and 52 patients with simple bronchiectasis in the control group. Basic information, imaging features, serum albumin levels, and infection indicators were collected from both groups of patients.Univariate and multivariate logistic regression analysis were performed to analyze the risk factors for NTM-PD in patients with bronchiectasis. RESULTS Multivariate logistic regression analysis revealed that bronchiectasis exacerbation occurring at least twice a year(OR = 3.884, 95% CI: 1.200-12.568), involvement of three or more lung lobes with bronchiectasis (OR = 3.932, 95% CI: 1.208-12.800), hypoalbuminemia (OR = 3.221, 95% CI: 1.015-10.219), and the NLR index (OR = 1.595, 95% CI: 1.200-2.119) were significant risk factors for non-tuberculous mycobacteria pulmonary disease in individuals with bronchiectasis (P < 0.05). CONCLUSION Patients with bronchiectasis accompanied by NTM-PD present specific risk factors that should be promptly addressed through prevention and treatment.

Peripheral Neutrophil-to-Lymphocyte Ratio in Bronchiectasis: A Marker of Disease Severity. Biomolecules 2022; 12:biom12101399. [PMID: 36291608 PMCID: PMC9599714 DOI: 10.3390/biom12101399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 09/22/2022] [Accepted: 09/28/2022] [Indexed: 11/17/2022] Open
Abstract
Most patients with bronchiectasis have a predominantly neutrophilic inflammatory profile, although other cells such as lymphocytes (as controllers of bronchial inflammation) and eosinophils also play a significant pathophysiological role. Easy-to-interpret blood biomarkers with a discriminative capacity for severity or prognosis are needed. The objective of this study was to assess whether the peripheral neutrophil-to-lymphocyte ratio (NLR) is associated with different outcomes of severity in bronchiectasis. A total of 1369 patients with bronchiectasis from the Spanish Registry of Bronchiectasis were included. To compare groups, the sample was divided into increasing quartiles of NLR ratio. Correlations between quantitative variables were established using Pearson's P test. A simple linear regression (with the value of exacerbations as a quantitative variable) was used to determine the independent relationship between the number and severity of exacerbations and the NLR ratio. The area under the curve (AUC)-ROC was used to determine the predictive capacity of the NLR for severe bronchiectasis, according to the different multidimensional scores. Mean age: 69 (15) years (66.3% of women). The mean NLR was 2.92 (2.03). A higher NLR was associated with more severe bronchiectasis (with an especially significant discriminative power for severe forms) according to the commonly used scores (FACED, E-FACED and BSI), as well as with poorer quality of life (SGRQ), more comorbidities (Charlson index), infection by pathogenic microorganisms, and greater application of treatment. Furthermore, the NLR correlated better with severity scores than other parameters of systemic inflammation. Finally, it was an independent predictor of the incident number and severity of exacerbations. In conclusion, the NLR is an inexpensive and easy-to-measure marker of systemic inflammation for determining severity and predicting exacerbations (especially the most severe) in patients with bronchiectasis.

Abstract
OBJECTIVE Inflammatory biomarkers, such as absolute neutrophil and lymphocyte counts, neutrophil-to-lymphocyte ratio (NLR), platelet (PLT)-to-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR), are associated with the progression and development of several disorders. Although patients with Cushing syndrome (CS) have immunosuppression with altered leucocyte counts, the profile of the inflammatory biomarkers in these patients has not been extensively studied. DESIGN We compared a panel of inflammatory biomarkers in patients with active endogenous CS (n of complete blood count (CBC) reports = 319) and eucortisolemic subjects of similar age, gender and BMI (n of CBC reports = 93). Patients were divided into two age groups (6-12 years at the time of CBC and >12 years at the time of CBC) based on age differences in normal reference ranges. RESULTS Patients with CS had higher NLR vs controls (6-12 years: 2.47 (1.86, 3.32) vs 1.35 (1.11, 2.27), P < 0.0001; >12 years: 3.00 (2.23-4.17) vs 1.80 (1.23-2.31), P < 0.0001). Similarly, absolute neutrophil and lymphocyte counts, MLR and PLR differed between patients with CS and controls. The inflammatory biomarkers correlated with indices of cortisol secretion, such as midnight serum cortisol, 24-h urinary free cortisol and morning cortisol. On receiver operating characteristic analysis, NLR showed high area under the curve (AUC) (6-12 years: cutoff of 1.72 had AUC: 0.77, >12 years: cutoff of 2.35 had AUC: 0.81). CONCLUSIONS We conclude that multiple inflammatory biomarkers differed between patients with CS and controls suggesting substantial effects of hypercortisolemia on the immune system.

Abstract
Background. Cystic fibrosis (CF) is one of the most frequent genetic diseases. The discovery and implementation of new therapies prolonged the survival of CF patients in the last years. Evaluation of long-term complications could be useful to improve the outcome of these patients. Aim of the Study. To evaluate renal function, metabolic, nutritional, and inflammatory status in CF patients on cystic fibrosis transmembrane regulator (CFTR) modulators therapy as well as lung transplant recipients (LRs) and patients on conservative therapy (control group). Materials and Methods. We performed a prospective, longitudinal study on 69 CF patients. Clinical and laboratory parameters (metabolic and nutritional indices and inflammatory markers) were evaluated in all patients before starting CFTR therapy or transplant (T0) and after 3 years (T1). Results. We enrolled 69 CF patients (42 males). Patients were distributed into three groups. The average age was 35.01 ± 10.57 years for the control group (group 0), 32.47 ± 9.40 years for patients on CFTR modulators therapy (group 1), and 38.93 ± 7.14 years for LRs (group 2). At T1, we showed a significant difference among the three groups in terms of renal function indices: creatinine, eGFR, serum nitrogen as well as serum uric acid, sodium, and potassium (
,
,
,
,
, and
, respectively), particularly in LRs patients. Significant differences were found in nutritional status parameters among the three groups: total protein, serum albumin, serum fibrinogen, serum transferrin, and white blood cell counts (
,
,
,
, and
, respectively), particularly in LRs compared with other groups. Moreover, we found significant differences in metabolic profile (HbA1c,
) and inflammatory status, with a significant difference in C-reactive protein values, neutrophil counts, and neutrophil-lymphocyte ratio (NLR) among the three groups (
,
, and
, respectively). Conclusions. Our study showed a reduced renal function and poor nutritional status in LRs, along with worse metabolic control. Moreover, we showed a lower inflammatory status in patients on CFTR modulators therapy. Therefore, we suggest early and careful monitoring of renal function, metabolic, and nutritional parameters in CF patients, whether they are on conservative therapy, CFTR modulators therapy, and LRs patients.

Abstract
Introduction Bronchiectasis is a disorder resulting mainly from bronchial inflammation caused by recurrent or chronic infections. It is characterized by permanently dilated airways due to bronchial wall destruction. Exacerbations have a key role in bronchiectasis as they are associated with a negative impact on patient prognosis. Exacerbations are generally infectious events caused mostly by bacterial microorganisms. Infective or inflammatory agents cause neutrophil recruitment into the airways, which leads to proteolytic enzymes such as neutrophil elastase and matrix metalloproteinases release, resulting in airway matrix destruction. Neutrophil to lymphocyte ratio (NLR) is used as a biomarker of inflammation. It is calculated by dividing the number of neutrophils by the number of lymphocytes. Our aim is to evaluate Neutrophils to Lymphocyte Ratio in patients with bronchiectasis exacerbation and its correlation to microbiological data. Methods The study involved patients with a diagnosis of bronchiectasis based on high-resolution computerised tomography (HRCT) of the chest who fulfilled the criteria of bronchiectasis exacerbation. Complete blood counts with differential counts, which included total white blood cells, neutrophils and lymphocytes, were obtained. NLR and C-reactive protein (CRP) levels were measured in patients with bronchiectasis exacerbation and in healthy controls. NLR was calculated as the ratio of the neutrophils to lymphocytes. The mean NLR values in patients with bronchiectasis exacerbation were compared to mean NLR values in healthy controls. The NLR values were compared to CRP levels in patients with bronchiectasis exacerbation. Sputum cultures were performed in all patients. The mean NLR values in patients with positive sputum cultures were compared with mean NLR values in patients with negative sputum cultures, and mean NLR values in patients with isolated Pseudomonas aeruginosa in sputum cultures were compared to mean NLR values in patients with other infectious agents isolated. Results The study population consisted of 80 patients with bronchiectasis exacerbation - 54 males and 26 females - with a mean age of 77.3±8.4 years, and 64 healthy controls - 36 males and 28 females - with a mean age of 62.9±15.3 years. The mean CRP levels in patients with bronchiectasis exacerbation were 75.03±73.87 mg/l. The mean NLR value in patients with bronchiectasis exacerbation was 9.2±7.8 and the mean NLR value of controls was 3.1±2.9 (p<0.001). The NLR values in patients with bronchiectasis exacerbation had no linear correlation with CRP values in these patients (r=0.002, p=0.992). Fifty-two patients had positive sputum cultures and 28 patients had negative sputum cultures. The mean NLR value in patients with positive sputum cultures was 10.5±9.1, and in patients with negative sputum cultures, it was 6.7±3.6 (p<0.012). The mean NLR value in patients with P.aeruginosa was 10.1±9.5, and in patients with other microorganisms isolated, it was 10.8±8.9 (p=0.784). Conclusions Neutrophil to lymphocyte ratio values are statistically greater in patients with bronchiectasis exacerbation compared to healthy controls. There is no linear correlation between NLR and CRP in these patients. NLR values are statistically greater in patients with positive sputum cultures compared to those with negative sputum cultures. Therefore, NLR can be used for predicting positive cultures in patients with bronchiectasis exacerbation.

Int Arch Otorhinolaryngol 2020; 25:e229-e234. [PMID: 33968225 PMCID: PMC8096515 DOI: 10.1055/s-0040-1709194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 02/17/2020] [Indexed: 11/16/2022] Open
Abstract
Introduction
There are no definitive parameters to guide the etiology and severity of pediatric antrochoanal polyps.
Objective
The aim of our study is to compare the values of blood cell distribution parameters in cases of pediatric antrochoanal polyps (ACPs) with those of the control group. These values may be guiding parameters in determining the etiology of ACPs and evaluating the severity of the disease and the risk of recurrence.
Methods
Blood count values of patients operated for pediatric ACPs were retrospectively analyzed and compared with the data of the control group with the same age and gender distribution. The ACPs group was divided into subgroups in terms of inflammation, severity, and recurrence, and these subgroups were statistically compared as well.
Results
When the ACP patient group and the control group were compared, there was no statistically significant difference between the two groups. When we compared the patients considering the CT findings, there was a statistically significant difference between the stage III patients and the control group in terms of mean platelet volume (MPV) and platelet-to-lymphocyte ratio (PLR) values (
p
< 0.05 in both). Similarly, the MPV and PLR values were significantly higher in the recurrence patient group than in the control group. (
p
< 0.05 in both).
Conclusion
As a result of the data obtained, it can be suggested that inflammatory parameters in pediatric cases of ACPs vary in terms of recurrence and the severity of the disease.

Abstract
BACKGROUND Mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have all been investigated as novel inflammatory markers of cardiac and oncological diseases, while there is only a limited number of studies investigating these markers in chronic obstructive pulmonary disease (COPD). In the present study we examine NLR, PLR; and other markers, such as eosinophil, MPV, plateletcrit (PCT), platelet distribution width (PDW), red cell distribution width (RDW), and C-reactive protein (CRP) in patients with stable and acute exacerbation of COPD. METHODS Stable COPD (Group 1, n=140), COPD with acute exacerbation (Group 2, n=110), and healthy controls (Group 3, n=50) were included in the study. Leukocyte, CRP, hemoglobin (HB), RDW, platelet, MPV, PCT, PDW, neutrophil, lymphocyte, eosinophil, NLR, and PLR were analyzed in all groups. RESULTS HB, leukocyte, platelet, neutrophil, eosinophil, MPV, PCT, CRP, NLR, and PLR were significantly higher, while the lymphocyte was lower in Group 1 than in Group 3. Leukocyte, neutrophil, RDW, CRP, NLR, and PLR were significantly higher, while lymphocyte was lower in Group 2 than in Group 3. Leukocyte, neutrophil, RDW, CRP, NLR, and PLR were significantly higher, while HB, platelet, MPV, PCT, and lymphocyte were significantly lower in Group 2 than in Group 1. NLR and PLR increased significantly in patients with bronchiectasis when compared to those without in Group 1. CONCLUSIONS Our study results suggest that NLR, PLR and RDW can be used as simple and cost-effective markers for the evaluation of severity of exacerbation and for predicting hospitalization and further exacerbations in patients with COPD.
