Neutrophil to lymphocyte and platelet to lymphocyte ratio in patients with dipper versus non-dipper hypertension

Background: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are associated with worse outcome in various diseases. Non-dipping blood pressure pattern is associated with higher cardiovascular mortality. The aim of this study was to explore the association between NLR and PLR in patients with dipper versus non-dipper hypertension.

Methods: The study included 166 patients with hypertension. Eighty-three patients (40 male, mean age: 49.1?±?10.5 years) had dipper hypertension, while 83 patients (41 male, mean age: 52.3?±?12.7 years) had non-dipper hypertension.

Results: Baseline demographic characteristics were similar in both groups. Patients with non-dipper hypertension had significantly higher NLR compared to dipper hypertension (2.3?±?0.9 versus 1.8?±?0.5, p?p?=?0.001). In univariate analysis, hyperlipidemia, smoking, presence of diabetes, PLR more than 107 and NLR more than 1.89 were among predictors of dipper and non-dipper status. In logistic regression analyses, only hyperlipidemia (odds ratio: 2.96, CI: 1.22–7.13) and PLR more than 107 (odds ratio: 2.62, CI: 1.13–6.06) were independent predictors of dipper and non-dipper status. A PLR of 107 or higher predicted non-dipper status with a sensitivity of 66.3% and specificity of 68.7%.

Conclusion: We demonstrated that patients with non-dipper hypertension had significantly higher NLR and PLR compared to dipper hypertension, which has not been reported previously. Moreover PLR more than 107 but not NLR was independent predictor of non-dipper status.     

Neutrophil to lymphocyte and platelet to lymphocyte ratios in systemic lupus erythematosus: Relation with disease activity and lupus nephritis

ObjectivesTo investigate the role of neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) as activity markers in systemic lupus erythematosus (SLE) without nephritis and lupus nephritis (LN) patients.Patients and methodsThis study included 60 SLE patients with LN, 60 SLE patients without renal involvement and 30 healthy controls. We analyzed correlations between NLR and PLR and both disease activity and renal affection.ResultsThe NLR of SLE patients was much higher than those of the controls. Both ratios showed significantly increased values in SLE patients with active disease. NLR and PLR were positively correlated with SLEDAI, ESR, and CRP and negatively correlated with C4. SLE patients with LN had higher levels of NLR than those without nephritis. NLR showed positive correlations with BUN, serum urea, serum creatinine and 24 h urinary protein. We found NLR to be related to anti-ds-DNA level and renal biopsy classes. While PLR was related only to anti ds-DNA. The best NLR to predict SLE active disease was 2.2 and the best PLR cut-off value was 132.9.ConclusionNLR and PLR are useful inflammatory markers to evaluate disease activity in SLE patients. Also, NLR could reflect renal involvement in SLE patients and is associated with the different classes of its histological staging.     

Platelet to lymphocyte ratio as a novel indicator of inflammation is correlated with the severity of metabolic syndrome: A single center large-scale study

Metabolic syndrome (MetS) as a cluster of several cardio-metabolic components is rapidly growing public-health problem worldwide and significantly associated with poor cardiovascular outcomes. Increased visceral adiposity activates the important pathways connecting low-grade chronic inflammation, oxidative stress and blood coagulation. Recently, platelet to lymphocyte ratio (PLR) has been evidenced as a novel indirect inflammatory marker. Therefore, for the first time, we aimed to investigate the association of PLR with both the presence and severity of MetS. In this cross-sectional study, a total of 1146 participants were enrolled (n?=?539 with MetS and n?=?607 without MetS). MetS was defined according to NCEP-ATP III criteria. MetS (+) group revealed significantly higher PLR and C-reactive protein (CRP) levels as compared to MetS (?) group (p?p?r?=?0.163, p?p?p?p?相似文献   

Implications of blood indices in systemic lupus erythematosus patients: Two feasible determinants of disease activity and lupus nephritis

Aim of the workTo investigate whether or not neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) may by indicators of disease activity in systemic lupus erythematosus (SLE) with and without lupus nephritis (LN).Patients and methodsThis research was carried out on 40 adult SLE patients (20 with LN and 20 without) and 20 controls. The NLR and PLR were calculated. The SLE disease activity index (SLEDAI) was assessed.ResultsThe mean age of the patients was 36.2 ± 7.6 years, 38 females and 2 males (F:M 19:1), with a disease duration of4.3 ± 1.2 years. The mean SLEDAI was 15.1 ± 4.7 being significantly higher in those with LN (17.5 ± 3.5) compared to those without (12.6 ± 4.6) (p = 0.001). The mean NLR (6.1 ± 2.1) and PLR (236.6 ± 86.9) were significantly increased in patients compared to the control (2.7 ± 1.2 and 125.2 ± 38.8 respectively) (p < 0.001). The NLR and PLR were both significantly related to the serum creatinine (r = 0.35, p = 0.03 and r = 0.5, p = 0.001) and SLEDAI (r = 0.36, p = 0.03 and r = 0.34, p = 0.03 respectively). NLR can significantly predict activity of SLE at cut off 5.6 with a sensitivity 80%, specificity 65% (p = 0.007) and PLR at cut off 217 with sensitivity 75%, specificity 65% (p = 0.035). The NLR can significantly predict LN at cut off 3.6 (sensitivity 80%, specificity 40%; p = 0.007) and PLR at cut off 186 (sensitivity 70%, specificity 60%; p = 0.035).ConclusionThere is a remarkable link between PLR and NLR with SLEDAI. Thus, both may serve as promising affordable indicators of inflammation in SLE. The notable relation to LN may signal renal involvement in patients with SLE.     

Noninvasive evaluation of gastric emptying and gastric wall thickness in SLE patients

Objective: The objective of this study is to evaluate the gastric emptying in patients with systemic lupus erythematosus (SLE) with gastrointestinal involvement using three-dimensional (3D) ultrasonography.

Methods: The gastric emptying times at 25% (T1), 50% (T2), and 75% (T3) of SLE patients with gastrointestinal involvement (n?=?40) and healthy controls (n?=?80) were evaluated and compared. In addition, the correlations among the gastric wall thickness, SLE disease activity index (SLEDAI), and upper gastrointestinal symptoms were calculated.

Results: The gastric wall thickness was correlated with the SLEDAI (r?=?0.928, p?<?0.001) and the upper gastrointestinal symptom index (r?=?0.848, p?<?0.001). The emptying times T1, T2, and T3 of the SLE patients were 17.08?±?2.65?min (mean?±?standard deviation), 39.85?±?6.54?min, and 83.58?±?7.12?min, respectively. For healthy controls, they were 19.65?±?5.39?min, 41.08?±?7.51?min, and 70.34?±?8.03?min. The T1 of the SLE patients was shorter (p?<?0.01), while the T3 was longer (p?<?0.001). Moreover, T3 in the SLE group had the best correlation with the upper gastrointestinal symptom index (r?=?0.553, p?<?0.001). T1 in the SLE group was anti-correlated with early satiety (r?=??0.366, p?<?0.05).

Conclusions: Combining the emptying times T1 and T3, as well as the gastric wall thickness, the SLEDAI and the upper gastrointestinal symptoms index can provide accurate clinical diagnosis of SLE with gastric involvement.     

Mean platelet volume as an indicator of disease activity in juvenile SLE

The aim of the study was to assess mean platelet volume (MPV) in children with systemic lupus erythematosus (SLE) at the active and inactive stages. Twenty children with SLE and 30 age- and gender-matched controls were enrolled. Demographic data, SLE disease activity index (SLEDAI), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), MPV, complement 3 (C3), complement 4 (C4), urine protein (Up), and urine creatinine (Ucr) values upon reactivation and remission phases were recorded. MPV was statistically higher in patients than in controls and significantly increased in active phase compared to inactive phase (p?=?0.001). A MPV level of 8.4 fL was determined as predictive cutoff value of activation of SLE (sensitivity 75 %, specificity 90 %). MPV was positively correlated with SLEDAI (p?=?0.01, r?=?0.55), ESR (p?=?0.01, r?=?0.45), CRP (p?=?0.04, r?=?0.24), and Up/Ucr (p?=?0.01, r?=?0.45) and negatively correlated with C3 (p?=?0.02, r?=??0.36), albumin (p?=?0.01, r?=??0.63), and Hb (p?=?0.01, r?=??0.48). There was not any significant association between MPV and the histological classification of lupus nephritis (p?=?0.65). MPV might be used as an early indicator of reactivation in children with SLE. MPV seemed to be more accurate than ESR, CRP, and C3 for monitoring the disease activity in SLE.     

Pre‐treatment neutrophil/lymphocyte ratio and platelet/lymphocyte ratio are prognostic of progression in early stage classical Hodgkin lymphoma

To determine whether pre‐treatment neutrophil/lymphocyte (NLR) or platelet/lymphocyte ratios (PLR) are predictive for progression in early‐stage classical Hodgkin lymphoma (cHL), we derived NLR and PLR values for 338 stage I/II cHL patients and appropriate cut‐off point values to define progression. Two‐year freedom from progression (FFP) for patients with NLR ≥6·4 was 82·2% vs. 95·7% with NLR <6·4 (P < 0·001). Similarly, 2‐year FFP was 84·3% for patients with PLR ≥266·2 vs. 96·1% with PLR <266·2 (P = 0·003). On univariate analysis, both NLR and PLR were significantly associated with worse FFP (P = 0·001). On multivariate analysis, PLR remained a significant, independent prognostic factor (P < 0·001).     

Platelet to lymphocyte ratio as a prognostic marker in primary percutaneous coronary intervention

We assessed the prognostic value of the platelet to lymphocyte ratio (PLR) in primary percutaneous coronary intervention (pPCI). Patients (n?=?440) with acute myocardial infarction (AMI) who underwent pPCI were divided into 2 groups: low PLR (<137) and high PLR (>137). “Thrombolysis In Myocardial Infarction” (TIMI) flow grades and Syntax scores (SXS) were calculated from initial angiograms. In-hospital mortality rate and cardiac adverse events were obtained from medical records. Patients with high PLR had more no-reflow, higher SXS and higher mortality rate (p?<?0.001, p?<?0.001 and p?=?0.008, respectively). In receiver operating characteristic curve analysis, high PLR predicted development of no-reflow (specificity 71% and sensitivity 85%), SXS>22 (specificity 52% and sensitivity 61%) and adverse events (specificity 67% and sensitivity 63%). In multivariate regression analysis, PLR was an independent risk factor for no-reflow, SXS>22 and in-hospital adverse events. In addition to PLR, we present the relationship between mean platelet volume, red cell distribution width and neutrophil to lymphocyte ratio and no-reflow, SXS and in-hospital adverse events.     

Neutrophil/lymphocyte ratio but not platelet/lymphocyte ratio and mean platelet volume can be an indicator of subclinical inflammation in patients with Familial Mediterranean Fever

Aim of the work: To evaluate the value of three hematological indices to determine subclinical inflammation in Familial Mediterranean Fever (FMF) patients during attack-free period. Patients and methods: This study included 60 FMF patients without FMF-related symptoms or signs in the preceding month and 50 age and sex matched healthy control. Subclinical inflammation was defined as the presence of elevated C-reactive protein (CRP) > 5 mg/dL and/or serum amyloid A (SAA) levels > 6.4 mg/L in the absence of any FMF related clinical signs and symptoms. The neutrophil/lymphocyte ratio (NLR), the platelet/lymphocyte ratio (PLR) and mean platelet volume (MPV) were evaluated. Results: The median age of the patients was 32 and 80% were females. They were 12 (80%) with subclinical inflammation and 48 (80%) without. Mutations of MEFV gene were analyzed in 43 (56.6%) patients and were homozygous in 21, heterozygous in 12 and compound heterozygous in 10. The most common mutation was of M694V. The NLR and PLR were significantly higher and MPV lower in patients with inflammation (p = 0.002, p = 0.02, p = 0.03, respectively) but was comparable to the values in the control. Only NLR was significantly higher in those with inflammation compared to those without (p = 0.009) whereas MPV and PLR were similar (p = 0.45 and p = 0.22, respectively). The best cut-off value for NLR in predicting subclinical inflammation in patients was 2.94 (sensitivity 66.7%, specificity 94.9%;p = 0.009). Conclusions: Only NLR increased in FMF patients with subclinical inflammation which may be used as a marker in determining early activity or flare in addition to other markers.     

Neutrophil/lymphocyte and platelet/lymphocyte ratios are useful predictors comparable to serum IL6 for disease activity and damage in naive and relapsing patients with lupus nephritis

Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have become recently useful as predictive and prognostic tools in patients with various medical conditions.Aim of the workTo evaluate NLR and PLR in systemic lupus erythematosus (SLE) and their relation to disease clinical characteristics, nephritis, disease activity and damage.Patients and methodThe study involved 110 Egyptian SLE patients; 80 with lupus nephritis (naive and relapsing) and 30 without as well as 50 matched control. Patients were subjected to full clinical examination, SLE disease activity index (SLEDAI) scoring, and damage using Systemic Lupus International Collaborating Clinics Damage Index (SLICC-DI). Laboratory and immunology profiles included the complete blood count (CBC) with differential white blood cell counts and estimation of both NLR and PLR, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), protein/creatinine ratio, anti-nuclear antibody (ANA), anti-double stranded deoxyribonucleic acid (anti-dsDNA), serum complements and interleukin-6 (IL-6) levels.ResultBoth NLR and PLR were significantly higher in SLE patients (4.8 ± 1.4 and 281.7 ± 66.7 respectively) compared to controls (3.8 ± 2 and 138.2 ± 50.4). Both ratios were significantly elevated in patients with active lupus nephritis (at presentation or as a flare) and were comparable between naive and relapsing lupus nephritis patients. In lupus nephritis patients, NLR and PLR significantly correlated with proteinuria, ESR, hypocomplementemia, IL6, SLEDAI and SLICC-DI. The best NLR cut-off value to predict nephritis activity was 5.65, whereas the best PLR cut-off value was 316.5.ConclusionNLR and PLR appear to be potentially useful cheap parameters of activity, relapse and severity in SLE patients with nephritis.     

New inflammatory markers in pre-eclampsia: echocardiographic epicardial fat thickness and neutrophil to lymphocyte ratio

Background: Increased epicardial fat thickness (EFT) has been proposed as a new cardiometabolic risk factor. The neutrophil/lymphocyte ratio (NLR) has predictive and prognostic value in several cardiovascular diseases. The aim of this study was to explore the association between EFT and NLR in patients with pre-eclampsia.

Methods: Hundred and eight pregnant patients with a mean age of 30.6?±?6.3 years were included in the study. Patients were divided into two groups based on the presence of pre-eclampsia. All participants underwent transthoracic echocardiography imaging, and complete blood counts were measured by an automated hematology analyzer. Statistical analysis was performed using the Chi-square, Mann–Whitney U, correlation and logistic regression tests, and receiver operating characteristic (ROC) analysis.

Result: The mean EFT value of the pre-eclampsia group was significantly higher than the control group (6.9?±?0.6 versus 5.6?±?0.6; p?p?Conclusion: Unlike many other inflammatory markers and bioassays, NLR and echocardiographic EFT are inexpensive and readily available biomarkers that may be useful for risk stratification in patients with pre-eclampsia.     

Prognostic meaning of neutrophil to lymphocyte ratio (NLR) and lymphocyte to monocyte ration (LMR) in newly diagnosed Hodgkin lymphoma patients treated upfront with a PET-2 based strategy

Recent reports identify NLR (the ratio between absolute neutrophils counts, ANC, and absolute lymphocyte count, ALC), as predictor of progression-free survival (PFS) and overall survival (OS) in cancer patients. We retrospectively tested NLR and LMR (the ratio between absolute lymphocyte and monocyte counts) in newly diagnosed Hodgkin lymphoma (HL) patients treated upfront with a PET-2 risk-adapted strategy. NLR and LMR were calculated using records obtained from the complete blood count (CBC) from 180 newly diagnosed HL patients. PFS was evaluated accordingly to Kaplan-Meier method. Higher NLR was associated to advanced stage, increased absolute counts of neutrophils and reduced count of lymphocytes, and markers of systemic inflammation. After a median follow-up of 68 months, PFS at 60 months was 86.6% versus 70.1%, respectively, in patients with NLR?≥?6 or NLR?<?6. Predictors of PFS at 60 months were PET-2 scan (p?<?0.0001), NLR?≥?6.0 (p?=?0.02), LMR?<?2 (p?=?0.048), and ANC (p?=?0.0059) in univariate analysis, but only PET-2 was an independent predictor of PFS in multivariate analysis. Advanced-stage patients (N?=?119) were treated according to a PET-2 risk-adapted protocol, with an early switch to BEACOPP regimen in case of PET-2 positivity. Despite this strategy, patients with positive PET-2 still had an inferior outcome, with PFS at 60 months of 84.7% versus 40.1% (negative and positive PET-2 patients, respectively, p?<?0.0001). Independent predictors of PFS by multivariate analysis were PET-2 status and to a lesser extend NLR in advanced stage, while LMR maintained its significance in early stage. By focusing on PET-2 negative patients, we found that patients with NLR?≥?6.0 or LMR?<?2 had an inferior outcome compared to patients with both ratios above the cutoff (78.7 versus 91.9 months, p?=?0.01). We confirm NLR as predictor of PFS in HL patients independently from stage at diagnosis. Integration of PET-2 scan, NLR and LMR can result in a meaningful prognostic system that needs to be further validated in prospective series including patients treated upfront with PET-2 adapted-risk therapy.     

Correlation of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV) with gout activity: A monocentric and retrospective study

To evaluate the correlation of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV) with parameters related to gout activity. The general data of the patients and healthy controls (HCs), including complete blood count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum uric acid (SUA), and the presence of tophi were retrospectively analyzed. NLR, MPV, and PLR were calculated in patients with intercritical gout and gout flares. Correlation of the 3 markers with clinical features, like ESR, CRP, SUA, and the presence of tophi, were analyzed. The results revealed that NLR and PLR were elevated and MPV was markedly decreased in patients with gout compared with HCs (all P < .05). In patients with gout flares, NLR, and PLR were higher and MPV was lower than in intercritical gout patients (all P < .05). NLR and PLR were positively correlated with ESR and CRP, whereas MPV was negatively correlated with ESR. NLR, PLR, and MPV showed no obvious correlation with SUA and the presence of tophi. The receiver operating characteristic curve showed that NLR was more valuable in assessing gout disease activity. NLR, PLR, and MPV were correlated with inflammatory parameters in gout; they may be used as complementary tools to evaluate gout activity.     

Neutrophil-lymphocyte ratio is associated with arterial stiffness in patients with peritoneal dialysis

Background

Patients with peritoneal dialysis are in the persistent inflammation state and have elevated arterial stiffness. Neutrophil-lymphocyte ratio(NLR) is a new inflammatory marker in renal and cardiac disorders. Brachial-ankle pulse wave velocity (baPWV) is a non-invasive measurement, which is widely used as a surrogate marker of arterial stiffness. However, there is little evidence to show an association between NLR and baPWV in patients with peritoneal dialysis. The aim of this cross-section study was to investigate the relationship between NLR and arterial stiffness measured by baPWV in patients with peritoneal dialysis.

Methods

In this cross-section study, 101 patients with peritoneal dialysis were enrolled from January 2014 to June 2015. According to average baPWV level (1847.54 cm/s), the patients were categorized into two groups, low group and high group. baPWV, which reflects arterial stiffness, was calculated using the single-point method. Clinical data were collected in details. NLR was calculated using complete blood count. Associations between NLR and baPWV were assessed using Pearson’s correlation and linear regression analysis.

Results

The NLR was significantly lower in the low baPWV group than in the high baPWV group (p?=?0.03). There were positive correlations between baPWV and neutrophil count (r?=?0.24, p?=?0.01) and NRL(r?=?0.43, P?<?0.01), and there was a negative correlation between baPWV and lymphocyte count (r?=?-0.23, p?=?0.01). In addition, albumin, phosphorous and intact parathyroid hormone showed negative correlations with baPWV (r?= ?0.32, p?<?0.01; r?= ?0.28, p?<?0.01; r?= ?0.25, p?=?0.01, respectively). Age and hsCRP showed positive correlations with baPWV (r?=?0.47, p?<?0.01; r?=?0.25, p?=?0.01). In multivariate analysis, NLR independently correlated with baPWV in patients with peritoneal dialysis (β?=?0.33, p?<?0.01), even after adjustment for various confounders.

Conclusion

Our study suggests that NLR was an independently associated with arterial stiffness in patients with peritoneal dialysis. However, further prospective studies are needed to confirm cause-and-effect relationship between NLR and baPWV, and to investigate whether anti-inflammatory treatment could improve arterial stiffness in patients with peritoneal dialysis.

     

Assessment of neutrophil to lymphocyte ratio,C-reactive protein,mean platelet volume in obese,and nonobese patients with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is associated with low-grade chronic inflammation.This was a retrospective case–control study.In the present study, the risk coefficients of neutrophil to lymphocyte ratio (NLR), high-sensitive C-reactive protein (hs-CRP), and mean platelet volume (MPV) in obese patients with PCOS were determined. This study was designed to investigate NLR, hs-CRP, and MPV levels in 68 obese patients with PCOS and 44 nonobese patients with PCOS, and our study group was matched with 47 obese and 43 nonobese controls, respectively.PCOS group had higher MPV, NLR, insulin, glucose, and HOMA-IR rates than those of the controls. Subgroup analyses revealed that the obese PCOS group had higher NLR, hs-CRP, and MPV levels compared to those of controls. The obese PCOS group had higher NLR, hs-CRP, and MPV levels compared to those of the nonobese PCOS group. The odds ratios and 95% confidence intervals of those variables (NLR, hs-CRP, MPV) were found significant (P < .05). NLR, hs-CRP, and MPV variables were found statistically significant in the analysis of receiver operating characteristics.Our study demonstrated that NLR, hs-CRP, and MPV levels are increased in patients with obese PCOS.     

Pretherapy neutrophil to lymphocyte ratio and platelet to lymphocyte ratio do not predict survival in resectable pancreatic cancer

Background

Pretherapy serum neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have both been identified as prognostic in pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to identify the prognostic implication of pretherapy NLR and PLR in patients with resectable PDAC.

Persistent expression and function of P-glycoprotein on peripheral blood lymphocytes identifies corticosteroid resistance in patients with systemic lupus erythematosus

Corticosteroids (CS) are the mainstay of treatment in systemic lupus erythematosus (SLE) patients. However, some patients have poor response to CS treatment. Among the multiple mechanisms of CS resistance, overexpression of P-glycoprotein (P-gp) on peripheral blood lymphocytes (PBL) may be one of them as this result in efflux of CS from lymphocytes. Thus, we evaluated the role of P-gp protein on PBLs in patients with SLE in its response to CS therapy. SLE patients (n?=?42) (fulfilling ACR revised criteria) who were naïve to CS and immunosuppressive drugs were enrolled. Disease activity was assessed using SLE disease activity index (SLEDAI) and expression, and function of P-gp was evaluated by flow cytometry at baseline and after 3 months of therapy with CS. At 3 months, patients with SLEDAI >4 and SLEDAI ≤4 were grouped as nonresponders and responders, respectively. P-gp expression was significantly increased on PBLs of SLE patients as compared to healthy controls (p?<?0.001). P-gp expression and function correlated with SLEDAI (r?=?0.49, p?=?0.005; and r?=?0.49, p?=?0.001, respectively). P-gp expression and function were not different in responders and nonresponders at baseline. However, at 3 months of CS therapy, P-gp expression and function decreased in responders (p?<?0.001 and p?<?0.005, respectively), whereas in nonresponders, it remained unchanged. Persistent overexpression and activity of P-gp are associated with poor response to CS in CS naïve patients of SLE.     

Hematologic parameters and disease activity in patients with primary Sjögren's syndrome

Aim of the workTo evaluate hematologic parameters in patients with primary Sjögren's syndrome (PSS) and their association with disease activity.Patients and methodsSixty-five PSS patients and 65 age and sex matched control were studied. Neutrophil to lymphocyte ratio (NLR), mean platelet volume (MPV), red blood cells distribution width (RDW), platelet to lymphocyte ratio (PLR) and platelet count were evaluated. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured. The European league against rheumatism (EULAR) Sjögren's syndrome disease activity index (ESSDAI) was assessed.ResultsThe mean age of patients was 47.8 ± 12.1 years and disease duration 5.71 ± 1.2 years and they were 63 females and 2 males. The mean ESSDAI was 6.4 ± 7.9 (3–25). 11 had neurological involvement. 92.3% of patients received low-dose prednisolone (<10 mg/day) and hydroxychloroquine (HCQ). The mean NLR (1.83 ± 0.8), PLR (131.9 ± 32.5) and MPV (8.82 ± 1.4) in patients was significantly higher than in control (NLR 1.57 ± 0.56, PLR 109.9 ± 24.7 and MPV 7.71 ± 1.3; p = 0.036, p < 0.001 and p < 0.001 respectively). The RDW tended to be higher in patients (13 ± 1.56) compared to control (12.83 ± 1.13) (p = 0.46). There was a significant correlation between ESSDAI with NLR (r = 0.29, p = 0.02), RDW (r = 0.37, p = 0.002), ESR (r = 0.32, p = 0.01) and CRP (r = 0.33, p = 0.007) and between MPV with CRP (r = 0.27, p = 0.03) and between RDW and ESR (r = 0.36, p = 0.003).On regression analysis, NLR and RDW were significant predictors of disease activity (p = 0.01 and p = 0.02 respectively).ConclusionThe MPV, PLR and NLR, were significantly increased in PSS. NLR and RDW can be used as indicators of disease activity.
