Ocul Immunol Inflamm 2024:1-7. [PMID: 38626414 DOI: 10.1080/09273948.2024.2342378] [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: 12/13/2023] [Accepted: 04/08/2024] [Indexed: 04/18/2024]
Abstract
PURPOSE To evaluate the serum asymmetric dimethylarginine (ADMA) level as a biomarker for uveitis in Behçet's Disease (BD). METHODS In this cross-sectional study, two groups of BD patients were examined: 33 with uveitis and 27 without uveitis. All patients were clinically evaluated, with disease activity measured by Behçet's Disease Current Activity Form (BDCAF) score. They also underwent thorough ophthalmic evaluation, and routine laboratory investigations, including serum ADMA. RESULTS Patients with BD who experienced active or inactive uveitis had higher levels of serum ADMA compared to those without uveitis. Anterior (ρ = 0.34, p < 0.01), posterior (ρ = 0.3, p < 0.05), and pan uveitis (ρ = 0.35, p < 0.01) were significantly correlated with serum ADMA levels. However, there was no significant correlation between ADMA and other BD manifestations. ROC curve analysis showed that increased serum ADMA levels in BD patients predicted uveitis with a sensitivity of 61.8%, specificity of 96.2%, and AUC of 0.78(95% CI: 0.66-0.9, p < 0.001). CONCLUSION Serum ADMA level can serve as a novel biomarker of uveitis in BD and its severity with good diagnostic accuracy, regardless of its site or activity.

Abstract
PURPOSE To investigate the association of clinical findings and indocyanine green angiography (ICGA) score with inflammatory markers derived from complete blood count (CBC) parameters in patients with Vogt-Koyanagi-Harada (VKH) to determine the diagnostic and predictive role. METHODS Demographic characteristics, presenting complaints, ocular findings, optical coherence tomography findings, ICGA scores and best corrected visual acuity were recorded in treatment-naive VKH patients at presentation. Patients were divided into two groups as acute stage and chronic recurrent stage. CBC parameters were noted in patients at presentation and healthy controls (HC, n = 25). Neutrophil-lymphocyte-platelet-monocyte counts, neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), monocyte/lymphocyte and systemic immune-inflammation index (SII) were recorded. The association between these markers and clinical severity were evaluated. RESULTS Thirty-two patients with VKH (23 females/9 males) with a mean age of 34.1 ± 14.6 years were included in the study. There was an increase in neutrophil count, NLR and SII in patients with VKH compared to HC (p < 0.001). The cut-off values for these three parameters were 4.37, 2.24 and 562.35, respectively. Twenty-six patients presented in the acute stage and six patients presented in the chronic recurrent stage. Choroidal thickness, early stromal hyperfluorescence and total ICGA scores were higher in patients presenting in the acute stage (p < 0.001, 0.001 and 0.025, respectively). Patients with higher disease severity at presentation were treated earlier. Early stromal vessel hyperfluorescence and choroidal vasculitis scores were correlated with decreased lymphocyte count, increased NLR, PLR and SII (p < 0.05). CONCLUSION CBC-derived inflammatory parameters indicate that VKH is a systemic inflammation. These parameters can be used in the diagnosis and determination of disease severity of VKH.

Abstract
BACKGROUND Uveitis and posterior scleritis are sight-threatening diseases with undefined pathogenesis and accurate diagnosis remains challenging. METHODS Two plasma-derived extracellular vesicle (EV) subpopulations, small and large EVs, obtained from patients with ankylosing spondylitis-related uveitis, Behcet's disease uveitis, Vogt-Koyanagi-Harada syndrome, and posterior scleritis were subjected to proteomics analysis alongside plasma using SWATH-MS. A comprehensive bioinformatics analysis was performed on the proteomic profiles of sEVs, lEVs, and plasma. Candidate biomarkers were validated in a new cohort using ELISA. Pearson correlation analysis was performed to analyze the relationship between clinical parameters and proteomic data. Connectivity map database was used to predict therapeutic agents. RESULTS In total, 3,668 proteins were identified and over 3000 proteins were quantified from 278 samples. When comparing diseased group to healthy control, the proteomic profiles of the two EV subgroups were more correlated with disease than plasma. Comprehensive bioinformatics analysis highlighted potential pathogenic mechanisms for these diseases. Potential biomarker panels for four diseases were identified and validated. We found a negative correlation between plasma endothelin-converting enzyme 1 level and mean retinal thickness. Potential therapeutic drugs were proposed, and their targets were identified. CONCLUSIONS This study provides a proteomic landscape of plasma and EVs involved in ankylosing spondylitis-related uveitis, Behcet's disease uveitis, Vogt-Koyanagi-Harada syndrome, and posterior scleritis, offers insights into disease pathogenesis, identifies valuable biomarker candidates, and proposes promising therapeutic agents.

Abstract
Abstract
Background
Behcet’s disease (BD) does not have specific laboratory finding or pathological physical examination sign, and only few studies have investigated Neutrophil to lymphocyte ratio (NLR), platelets to lymphocytes ratio (PLR), lymphocytes to monocytes ratio (LMR), or mean platelet volume (MPV) values in patients with BD. We conducted this study to investigate the relationship between these indices and Behcet’s disease (BD) and to determine their relation to BD disease activity.
Results
This study is a case-control study that included 36 Behcet’s disease patients and 36 healthy controls. BD patients showed significant increase in the mean of NLR and PLR in comparison to control (P = 0.008 and 0.011) respectively, and highly significant decrease in LMR and MPV levels in BD patients in comparison to control (P < 0.001 and < 0.001) respectively. Also, we found that NLR, PLR, and LMR were significantly related to BD activity, and there were significant associations between the studied hematological parameters with some of muco-cutaneous, articular, gastrointestinal, eye, and nervous system manifestations in BD patients.
Conclusion
The blood indices NLR, PLR, LMR, and MPV are potential inflammatory markers that can be used to evaluate inflammatory status and disease activity in patients with BD. NLR and PLR showed positive relation being higher in active disease and also higher in highly active disease than in low disease activity. Also, LMR was significantly decreased in Behcet’s disease patients in relation to disease activity. Furthermore, NLR and PLR levels were significantly more associated with muco-cutaneous and nervous system involvement while, LMR levels were significantly associated with muco-cutaneous, articular, gastrointestinal and eye manifestations and MPV levels were associated with articular manifestations being significantly related to disease activity. These easily evaluated markers could help in the management of this disease with multisystem affection that are sometimes serious and potentially life threatening.

Abstract
Background NLR is a systemic inflammatory marker that have been associated with overall survival in patients with some rapidly progressive disease. There are few data about the diagnostic and predictive value of NLR in autoimmune diseases, and it has not been described in anti-MDA5 positive DM. We try to correlate neutrophil-to-lymphocyte ratio (NLR) with fatality from dermatomyositis in anti-MDA5 positive patients. Method A retrospective study in which 195 patients were enrolled was conducted. Clinical and laboratory information was collated and ratios of neutrophil to lymphocyte counts (NLR) calculated. The primary end point was all-cause death. Result Of the 195 patients studied, all had interstitial lung disease, including 140 survivors and 55 non-survivors. An optimal NLR cut-off value of 4.86 for mortality prediction was identified. The NLR of non-survivors was significantly higher than that of survivors (p < 0.001). Plasma levels of lactate dehydrogenase (LDH) and C-reactive protein were significantly increased when NLR was greater than 4.86. Results of multivariate analysis established that NLR > 4.86 was an independent predictor of mortality (HR: 2.52; 95%CI: 1.33–4.78; p = 0.005). Abstinence from smoking (HR: 2.66; 95%CI: 1.33–4.78; p = 0.003), emergence of rapidly progressive interstitial lung disease (RPILD; HR: 4.38; 95%CI: 2.37–8.08; p < 0.001), low plasma LDH (HR: 3.82; 95%CI: 2.06–7.11; p < 0.001) and presentation with dyspnea (HR: 2.17; 95%CI: 1.22–3.86; p = 0.009) were all protective factors predictive of survival. Conclusion NLR is a cost-effective and widely accessible biomarker with utility for risk stratification in patients with anti-MDA5 + dermatomyositis.

Abstract
PURPOSE Oral isotretinoin (ISO) can effect markers of inflammation in patients with acne vulgaris. Systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI) were described as novel inflammatory and prognostic biomarkers. The present study aimed to evaluate the effectiveness of SII, SIRI, and other inflammatory markers in patients with acne vulgaris who receive isotretinoin therapy. METHODS One hundred fifty-six patients with moderate-to-severe acne vulgaris who received at least 3 months of ISO treatment (0.5-1 mg/kg/day) and 100 healthy individuals were enrolled in the study. The medical records and laboratory findings of the participants were reviewed retrospectively. Pre-treatment and post-treatment neutrophil, lymphocyte, monocyte, and platelet counts, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte-lymphocyte ratio (MLR), SII, SIRI, total cholesterol, LDL cholesterol, triglyceride, HDL cholesterol, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were analysed. RESULTS Before ISO treatment, patients with moderate-to-severe acne vulgaris had significantly higher platelet counts than healthy controls (p = 0.003). Serum total cholesterol, LDL, triglyceride, AST, and ALT increased significantly after isotretinoin treatment in patients with acne vulgaris (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p = 0.029, respectively). In the follow-up of patients using ISO, a significant increase was found in platelet levels (p < 0.001). However, neutrophil, NLR, SII, and SIRI were found significantly decrease after ISO treatment (p = 0.047, p = 0.038, p = 0.003, p = 0.001; respectively). Lymphocyte, monocyte, PLR, and MLR did not show any significant change after ISO treatment. CONCLUSION SII and SIRI are better parameters as an indicator of the anti-inflammatory effect of isotretinoin than other inflammatory markers.

Abstract
BACKGROUND Behçet's disease (BD) is a multisystem autoinflammatory disease characterised by mucosal ulceration, ocular, neural, joint and skin inflammation. The cause of BD is not known but there is a strong genetic association with HLA-B*51, IL10 and IL23R. Neutrophils are a first line of defence against invading pathogens and have been described as activated in patients with BD. Neutrophils can now be separated into different subsets, such as low density (LDN) and normal density (NDN) that have diverse functional roles. We wished to address neutrophil heterogeneity in patients with BD. METHODS Peripheral blood neutrophils were obtained from 32 BD patients and 37 healthy aged-matched controls. Percoll isolation was used to isolate all neutrophils, while Ficol-Hypaque was used to obtain LDN and NDN. Phagocytic capacity and production of reactive oxygen species (ROS), and neutrophil extracellular traps (NET) stimulated with phorbol 12-myristate 13-acetate (PMA) and Escherichia coli (E.coli) were assessed in both groups. RESULTS We have demonstrated reduced phagocytic capacity and ROS production but greater NET production by total neutrophils stimulated with PMA or E.coli from BD patients in comparison with healthy controls. Patients with BD had elevated numbers of LDN and lower number of NDN compared with healthy controls. However, both neutrophil subsets showed the same reduced ROS production and phagocytic function as total neutrophils in both groups. CONCLUSION Our novel findings indicate that the neutrophil population in BD is heterogeneous and the increased number of LDN in combination with greater NET production may contribute to the inflammatory response and pathogenesis.

Abstract
INTRODUCTION Recurrent oral ulcers (ROUs) are the most common disorder of the oral cavity in the community. The most challenging issue for the clinician to deal with in the diagnosis is to distinguish whether ROUs are associated with primarily Behçet's disease (BD). We aimed to investigate whether hemogram parameters contribute to reinforce BD suspicion in the differential diagnosis of recurrent aphthous stomatitis (RAS) and BD. METHODS A total of 260 participants were recruited from the dermatology department in this single-centre, prospective, case-control study. Participants meeting eligibility criteria were divided into three groups as healthy control (n = 90), RAS (n = 97) and mucocutaneous BD (n = 73). The mean platelet volume (MPV), red cell distribution width (RDW), haemoglobin, neutrophils, monocyte, lymphocytes and platelet counts were evaluated with the complete blood count. Furthermore, the neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio and platelet/lymphocyte ratio were calculated. Erythrocyte sedimentation rate (ESR) and C-reactive protein were recorded. The contribution of hemogram parameters to the differentiation of BD from RAS was analysed. RESULTS The healthy control, RAS and BD groups were matched in terms of mean age (29.3 ± 5.8, 28.7 ± 5.6 and 29.9 ± 6.8 years; respectively) and sex distribution (women/men rate: 1.4, 1.6 and 1.7; respectively). ESR, neutrophil count and NLR were significantly higher in BD patients. (P = .032, P = .010, P = .019; respectively). MPV is significantly decreased in BD patients than in healthy control and RAS patients (P < .001). Decreased MPV (≤10 fL) and increased RDW (≥13.0%) were useful in predicting BD in patients evaluated with complaints of ROUs (OR = 9.98, 95% CI: [4.65-21.42], P < .001 and OR = 2.23, 95% CI: [1.14-3.36], P = .019, respectively). CONCLUSIONS Decreased MPV may be predictive for BD in selected patients with ROUs. We consider that more attention is required in terms of BD especially if MPV ≤10.0 fL.

Abstract
PURPOSE To evaluate the association of systemic immune-inflammation index (SII) levels, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) with severity of noninfectious uveitis. METHODS This retrospective study included 46 patients with noninfectious uveitis (uveitis group) and 46 age- and sex-matched healthy subjects (control group). The demographic and ocular findings, localization, and activity of uveitis were recorded at the time of onset evaluation. SII, NLR, and PLR levels of patients were compared between the groups. RESULTS SII, NLR, and PLR levels were significantly higher in uveitis group when compared to control group (p < 0.001, p = 0.005, and p = 0.001, respectively). While SII and NLR were significantly higher in severe anterior uveitis than mild anterior uveitis (p = 0.006 and p = 0.021, respectively), only SII was significantly higher in severe posterior and panuveitis than mild ones (p = 0.038). CONCLUSION SII, as a novel inflammation index, may be more significant tool than NLR and PLR in determining the severity of the uveitis. Furthermore, SII may be a potential useful index in clinical practice to follow-up and manage these patients by monitoring response to anti-inflammatory treatment modalities.

Abstract
PURPOSE To evaluate systemic inflammatory parameters in patients with corneal graft rejection after low-risk penetrating keratoplasty. METHODS Patients undergoing penetrating keratoplasty with indications of keratoconus, pseudophakic bullous keratopathy, and Fuchs endothelial dystrophy were analyzed retrospectively. Patients who had an endothelial rejection attack within two years post-transplant were included in the rejection group (n = 20), whereas patients with at least two years of post-transplant follow-up without graft rejection or failure were included in the control group (n = 46). All patients' clinical features and preoperative laboratory parameters were obtained from hospital records. The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio, and platelet-to-lymphocyte ratio of the groups were calculated and compared. RESULTS There was no difference between the two groups in terms of age, sex, indication, postmortem time and storage time of grafts, graft diameter, follow-up time, and common systemic diseases (p > 0.05). The NLR was found to be significantly lower in the rejection group when compared with the control group (2.04 ± 1.17, 2.66 ± 0.91, respectively, p = 0.023). There was no significant difference between the groups in terms of MLR and PLR (p = 0.243, p = 0.101, respectively). CONCLUSIONS Although a high NLR value, which is an indicator of systemic inflammatory condition, is associated with many ocular diseases, NLR was found to be lower in patients with a rejection episode after transplant surgery when compared with the control group. Further studies are needed to clarify the role of these hematologic parameters in graft rejection.

Abstract
Behçet's disease (BD) is a chronic disorder that involves multiple organs and is pathologically considered as a form of vasculitis. The current study aims to assess the metric properties of platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) in assessing BD disease activity. Three-hundred-nineteen patients with BD were enrolled in this cross-sectional study. Demographic and epidemiological data, including IBDDAM, time since the onset, and medication and manifestation history were recorded. Complete blood counts (CBC), NLR, and PLR were assessed by analyzing blood samples. On the last visit, patients were assessed for active manifestations of disease. IBDDAM and ocular IBDAAM scores were calculated for activity of disease in each patient. Both PLR and NLR were higher in patients with active BD (Mann-Whitney U test, p-value < 0.05). Patients with active ocular manifestation had significantly higher NLR and PLR (Mann-Whitney U test, p-value < 0.05). These ratios, however, were not associated with other active BD manifestations. A value of NLR > 2.58 had 46% sensitivity and 85% specificity for the diagnosis of active ocular manifestations (AUC: 0.690). NLR had a significant, though, weak positive correlation with IBDDAM (Spearman's rho = 0.162; p-value < 0.05) and ocular IBDDAM (Spearman's rho = 0.159; p-value < 0.05). Active Behçet's presented with higher NLR and PLR ratios; however, there was only a modest correlation between NLR and BD activity (IBDDAM score). Also, NLR and PLR have significant relationship with ocular features of BD patients.

Abstract
OBJECTIVE Recent studies have shown that chronic inflammation contributes to the development of sudden sensorineural hearing loss (SSNHL). Some hematologic parameters have also been linked to the prognosis of SSNHL. However, the prognostic value of such hematological factors is not conclusive. This study explored the association of routine hematological parameters with SSNHL. METHODS A systematic literature search was conducted in PubMed, Cochrane Library, Web of Science and Embase to identify eligible studies. Standardized mean deviation (SMD) and the 95% confidence interval (CI) were retried from relevant studies for analysis. Heterogeneity, subgroup, and publication bias analyses were performed. RESULTS A total of 18 studies involving 1505 SSNHL patients and 1466 healthy persons were enrolled in the final analysis. The study population included 699 responders and 458 non-responders to treatment. Pooled results revealed that the neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) value in the SSNHL patient group were higher than in the healthy group (SMD = 1.05, 95% CI: 0.86,1.24, p < 0.001, SMD = 0.52, 95% CI: 0.26,0.78, p < 0.001, respectively). However, there was no significant difference in the mean platelet volumes (MPV) between the groups (SMD = 0.03, 95% CI: 0.44, 0.49, p = 0.91). Notably, NLR and PLR values were evidently higher in the unrecovered group than in the recovered group (SMD = -0.63, 95% CI: 1.02, -0.23, p = 0.002, SMD = -0.4, 95% CI: 0.76, -0.03, p = 0.03, respectively). However, the MPV value was similar in both groups (SMD = -0.35, 95% CI: 1.14,0.44, p = 0.38). CONCLUSIONS Our results show that NLR and PLR values can predict the onset and prognosis of SSNHL.

Abstract
PURPOSE To compare complete blood count (CBC) parameters and neutrophil/lymphocyte ratio (NLR) between patients with infectious uveitis (IU) and those with non-infectious uveitis (NIU) during the first acute uveitis attack (AUA). METHODS The records of 119 patients admitted with the first AUA between 2016 and 2019 and whose diagnosis was unknown at the time of admission were retrospectively reviewed. The patients were divided into two groups, IU and NIU according to diagnoses after ocular and systemic workup. The IU group was also divided into subgroups as uveitis associated with local ocular infections and systemic infections. The complete blood count and associated indices of patients calculated from samples taken during the attack were compared between the groups. RESULTS A total of 60 NIU cases (mean age: 43.5 ± 11.6 years) and 59 IU cases (43.3 ± 14.7 years) were examined. Twenty-six of the NIU cases were female and 34 were male, while 32 of the IU cases were female and 27 were male. The localization of uveitis was similar in the IU and NIU groups (anterior: 11 vs. 18, intermediate: 3 vs. 6, posterior: 28 vs. 14, panuveitis: 17 vs. 22). The NLR values were significantly increased in patients with IU compared to those with NIU (p = 0.047). When the NLR is compared between NIU and subgroups of IU, this value was only found significantly increased in uveitis due to a systemic infection (n = 12) (p < 0.001). The mean white blood cell (WBC) count (p < 0.001) and neutrophil values (p < 0.001) were also observed significantly higher in the uveitis associated with systemic infectious diseases when compared with uveitis associated with local ocular infections and NIU group. CONCLUSION In the current study, NLR values are compared with autoimmune uveitis and systemic infectious uveitis for the first time in patients with AUA. This ratio has been found significantly higher in uveitis associated with systemic infections. The use of CBC parameters and indices, especially the NLR, may be instrumental in assessing patients presenting with first AUA, particularly when there is no clear explanation or underlying cause.

Abstract
Purpose: To evaluate whether the C-reactive protein (CRP)/albumin ratio (CAR) in patients with uveitis during an attack is a marker that can give information about the activity, severity and prognosis of the disease.Methods: This study included 35 patients with an uveitis attack and 35 healthy volunteers. The localization and severity of uveitis were recorded. Patients' complete blood count (CBC) during the attack, CRP, CAR, erythrocyte sedimentation rate(ESR), neutrophil/lymphocyte ratio(NLR), and platelet/lymphocyte ratio(PLR) were recorded.Results: The mean age was 34.1 ± 12.5 years for the 35 uveitis cases and 30.1 ± 4.1 years for the healthy volunteers. CRP and CAR were significantly higher in uveitis patients (p = .015 and 0.011, respectively). While CRP and CAR were significantly higher in severe anterior uveitis than mild anterior uveitis (p = .036 and 0.022, respectively), only CAR was significantly higher in severe posterior and panuveitis than mild ones(p = .017).Conclusion: CAR may be an important parameter in determining the activation of the uveitis.

Abstract
AIM To summarize the results of studies investigating neutrophil-to-lymphocyte ratio (NLR) and to identify the role of NLR in ocular diseases. METHODS With the aim of identifying the studies related to NLR, a search was conducted on http://www.ncbi.nlm.nih.gov/pubmed by utilizing the key words "neutrophil lymphocyte ratio, ocular diseases, and eye diseases" up to February 2018. All of the original articles were assessed according to date of publications, countries, clinics and topics. Studies about ocular inflammatory diseases were evaluated according to their qualifications, review methods and results. RESULTS A total of 4473 publications, including original research articles and reviews were screened. The number of publications was shown a regular logarithmic increase over the years. The majority of studies were performed by clinics in Turkey and many of these publications were performed by oncology and cardiology clinics. A total of 75 publications were identified to be about ocular diseases. CONCLUSION Elevated NLR as a cheap, reproducible, and readily available marker could be used as a diagnostic and/or prognostic marker in ocular diseases.

Abstract
Helicobacter pylori (H. pylori) is a common problem and a significant cause of chronic gastric inflammation. H. pylori, ongoing gastric inflammation and its severity are the most critical component of precursors of gastric cancer. Hypothetically, every chronic tissue injury activates platelets, and the mean platelet volume (MPV) reflects this action well. The potential relationship between H. pylori and platelet count has been shown before. However, there are few and conflicting papers about the relationship between MPV and H. pylori related chronic gastric inflammation and its severity. The study aimed to assess any potential relationship between MPV and presence of H. pylori, as well as the severity of chronic gastric inflammation. A total of 6890 endoscopic reports were initially evaluated, and a total of 218 dyspeptic patients having undergone upper endoscopy were included. Of these, 118 (54.2%) were H. pylori positive and 100 (45.8%) were H. pylori negative. At least four gastric biopsies were obtained and evaluated according to Sydney classification. Age, gender, hemoglobin, mean corpuscular volume, ferritin, serum iron and C-reactive protein, as well as endoscopic findings were also recorded. A p<0.05 was accepted as significant. The MPV and platelet count did not differ between H. pylori positive and H. pylori negative groups of patients (p>0.05). There were no differences and correlation between MPV and gastric inflammation severity according to Sydney classification (p>0.05). When stratifying MPV as <9.15 fL and >9.15 fL, there was no difference between H. pylori positive and H. pylori negative groups either (p>0.05). In this study, we found no relationship between MPV and presence of H. pylori or severity of gastric inflammation. Although there are still conflicting publications on this issue, in our opinion and according to the results of this study, MPV is not a suitable marker for evaluation of gastric inflammation severity, being H. pylori either positive or negative.

Abstract
The platelet-to-lymphocyte ratio (PLR) has emerged as an informative marker revealing shifts in platelet and lymphocyte counts due to acute inflammatory and prothrombotic states. PLR has been extensively examined in neoplastic diseases accompanied by immune suppression and thrombosis, which can be predicted by combined blood cell counts and their ratios. Several large observational studies have demonstrated the value of shifts in PLR in evaluating the severity of systemic inflammation and predicting infections and other comorbidities, in inflammatory rheumatic diseases. The value of PLR as an inflammatory marker increases when its fluctuations are interpreted along with other complementary hematologic indices, particularly the neutrophil-to-lymphocyte ratio (NLR), which provides additional information about the disease activity, presence of neutrophilic inflammation, infectious complications, and severe organ damage in systemic lupus erythematosus. PLR and NLR have high predictive value in rheumatic diseases with predominantly neutrophilic inflammation (e.g., Behçet disease and familial Mediterranean fever). High PLR, along with elevated platelet count, is potentially useful in diagnosing some systemic vasculitides, particularly giant-cell arteritis. A few longitudinal studies on rheumatic diseases have demonstrated a decrease in PLR in response to anti-inflammatory therapies. The main limitations of PLR studies are preanalytical faults, inadequate standardization of laboratory measurements, and inappropriate subject selection. Nonetheless, accumulating evidence suggests that PLR can provide valuable information to clinicians who encounter multisystem manifestations of rheumatic diseases, which are reflected in shifts in platelet, lymphocyte, neutrophil, or monocyte counts. Interpretation of PLR combined with complementary hematologic indices is advisable to more accurately diagnose inflammatory rheumatic diseases and predict related comorbidities.

Abstract
Behçet's disease (BD) is an uncommon autoimmune/autoinflammatory disease. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were investigated in many diseases as a marker of inflammation. In this study, we investigated NLR and PLR in patients with BD as a marker of disease activity and its association with different clinical manifestations. The study included 23 BD patients; their mean age was (32.5 ± 6.76) and M:F ratio was 16:7. Complete blood picture was done for all patients. NLR and PLR were compared in both active and inactive BD patients and its relation with different clinical manifestations was assessed. NLR was higher in active BD patients than in inactive BD patients (P < 0.01). Although both NLR and PLR were correlated with Behçet's Disease Current Activity Form (BDCAF), the correlation of NLR with BDCAF was much stronger than that of PLR. NLR was associated with some mucocutaneous lesions. Both NLR and PLR were associated with articular and GIT manifestations, but also NLR showed more significant results. In our studied patients, both NLR and PLR were not informative about any ongoing ocular activity (P > 0.05). Both ratios were not affected by the presence of neurologic deficits nor previous vascular events (P > 0.05). NLR was superior to PLR as an indicator of disease activity. NLR was closely related to skin manifestations while PLR was not. In our study, both were not considered reliable in representing ocular activity.

Abstract
OBJECTIVES Spontaneous bacterial peritonitis (SBP) is a common and high-mortality infectious complication of patients with cirrhosis. New inflammatory markers are associated with morbidity/mortality in various diseases. The aim of our study was to find the 30-day mortality rate of SBP and their predictors. PATIENTS AND METHODS Seventy patients with cirrhosis complicated with SBP and 55 non-SBP controls were enrolled into the study, and patients were evaluated for mortality rate and its predictors. RESULTS The 30-day and 3-month mortality rates in the SBP group were 26.1 and 50.7%, respectively. Mortality rates were higher in the SBP group than in the controls. Symptoms at hospital admission and cell counts in ascitic fluid made no difference in predicting 30-day mortality. Patients with SBP with high serum neutrophil counts, high neutrophil-lymphocyte ratio, high C reactive protein (CRP)/albumin ratio, and high model for end-stage liver disease (MELD) score had higher 30-day mortality rates. We determined optimal cutoff values of MELD scores and serum neutrophil counts for predicting 30-day mortality as 20.5 and 6850/mm, respectively. The sensitivity and specificity for the MELD cutoff value were 83.3 and 80.4%, respectively. We also followed up patients for 60 months after SBP; the patients with high inflammatory markers and MELD scores at the time of SBP diagnosis had worse survival compared with the group with lower levels. CONCLUSION Our results suggest that SBP has high 30-day mortality. MELD scores and inflammatory markers (CRP, CRP albumin ratio, neutrophil-lymphocyte ratio) may be used to predict mortality in patients with SBP.
