[PMID: 37997789 DOI: 10.1080/08820538.2023.2283028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 11/09/2023] [Indexed: 11/25/2023]
Abstract
PURPOSE The purpose of this study was to determine whether specific genetic polymorphisms affect the response to intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment in patients with macular oedema secondary to retinal vein occlusion (RVO). METHODS Participants in this prospective study were 50 patients with macular oedema secondary to RVO, who were treated with intravitreal ranibizumab or aflibercept, and were followed-up for 12 months after initiation of treatment. Five single nucleotide polymorphisms (SNPs) from three different genes (APOE, PON1, SDF-1) were examined as potential predictors for treatment response to intravitreal anti-VEGF agents. RESULTS Patients with the LL genotype of the PON1 L55M SNP had significantly higher reduction in central subfield thickness (CST) at month 12 after initiation of intravitreal anti-VEGF treatment (101.63 ± 56.80 μm in LL vs. 72.44 ± 39.41 μm in LM vs. 40.25 ± 19.33 μm in MM, p = .026). Patients with the M allele of the PON1 L55M SNP were significantly associated with lower reduction in CST compared to non-carriers (68.29 ± 38.77 μm in LM + MM vs. 101.63 ± 56.80 μm in LL, p = .032). CONCLUSION PON1 L55M SNP may serve as a promising genetic biomarker for predicting response to intravitreal anti-VEGF treatment in patients with macular oedema due to RVO.

Abstract
PURPOSE To assess changes in monocyte-to-high-density lipoprotein (HDL) ratio (MHR), neutrophil-to-lymphocyte ratio (NLR), and systemic immune-inflammation index (SII) with Graves' ophthalmopathy (GO) and their possible relation with GO disease activity and severity. METHODS A total of 20 patients with GO and 24 healthy controls were involved in the study. The thyroid status, MHR (monocyte count/HDL cholesterol level), NLR (neutrophil count/lymphocyte count) and SII [(neutrophil count × platelet count)/lymphocyte count] were compared between the groups. The relation of systemic inflammation parameters with disease activity and severity was evaluated. RESULTS The mean Clinical Activity Score (CAS) was 0.75 ± 0.78 in the GO group. None of the patients were active. The severity was mild for 14 (70.0%) patients and moderate-to-severe for 6 (30.0%) patients. MHR (17.28 ± 5.56 vs. 13.28 ± 5.08), NLR (2.51 ± 1.09 vs. 1.69 ± 0.53) and SII [600.42 (391.79-837.16) vs. 413.69 (344.26-603.82)] values were significantly increased in GO patients than in the controls (p = 0.017, p = 0.005 and p = 0.036, respectively). CAS was significantly correlated with MHR (r = 0.815, p < 0.001), NLR (r = 0.768, p = 0.017) and SII (r = 0.837, p < 0.001). The severity of GO was associated with increased MHR, NLR and SII (p = 0.019, p = 0.036 and p = 0.008, respectively). ROC analysis demonstrated that MHR, NLR and SII have a good ability to differentiate GO patients from healthy individuals. CONCLUSION GO patients have higher MHR and SII levels than healthy controls. Higher MHR, NLR and SII values were associated with increasing disease severity and activity, supporting the efficacy of these non-invasive, low-cost markers in determining the course of GO. Future prospective controlled trials are needed to elucidate the relation between inflammatory markers and GO.

Abstract
INTRODUCTION The aim of the study was to evaluate associations of peripheral blood immune cells and blood lipid profile levels with retinal vein occlusion (RVO). METHODS This retrospective study included 127 patients with RVO and 108 controls. Patients with RVO were divided into branch RVO (BRVO), central RVO (CRVO), ischemic RVO, or nonischemic RVO groups. Medical records were collected and analyzed. RESULTS The RVO group had higher mean neutrophil, triglyceride (TG), and monocyte/high-density lipoprotein (HDL) ratio (MHR) levels and lower HDL levels (p = 0.037, p < 0.001, p = 0.004, and p = 0.002, respectively). TG and MHR levels were significantly higher in the BRVO and CRVO groups compared with the control group (p < 0.001 and p = 0.016, respectively), but there was no difference in BRVO and CRVO group (p = 0.972 and p = 0.916, respectively). Mean HDL levels were significantly lower in the BRVO and CRVO groups than in the control group (p = 0.005), but the difference between the BRVO group and CRVO group was not significant (p = 0.290). Neutrophils, TG, and MHR were independent risk factors for RVO. HDL was an independent protective factor for RVO. Age was an independent risk factor for ischemic RVO. CONCLUSIONS Lower HDL, and higher neutrophil, TG, and MHR levels are associated with RVO. Age is an independent risk factor for ischemic RVO.

Abstract
PURPOSE To evaluate complete blood count (CBC)-derived inflammatory indices in central retinal artery occlusion (CRAO). METHODS A total of 42 patients with CRAO (CRAO group) and 42 age- and sex-matched subjects without CRAO (Control group) were included. CBC parameters including red cell distribution width (RDW) levels were assayed. Platelet/lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and neutrophil/ lymphocyte ratio (NLR) were calculated. RESULTS RDW, PLR, SII and NLR values were significantly higher in CRAO group than control group [15.2 ± 1.47% vs 13.96 ± 1.13% (p < .001), 127.94 ± 48.21 vs 101.16 ± 24.84 (p = .008), 667.11 ± 357.84 vs 493.44 ± 207.07 (p = .008), 2.70 ± 1.27 vs 2.13 ± 0.83 (p = .018), respectively]. In multivariate analysis only RDW was independent predictor for CRAO (OR 2.317, p < .001). On ROC analysis, area under curve of RDW, PLR, SII, and NLR for CRAO were 0.761, 0.685, 0.622 and 0.618, respectively. CONCLUSION RDW seems superior to other inflammatory indices to predict CRAO.

Abstract
Purpose To assess the predictive value of inflammatory blood biomarkers in rhegmatogenous retinal detachment (RRD) patients and its correlation with proliferative retinopathy (PVR) grade. Methods 82 RRD patients and 1 : 1 age- and gender-randomly matched cataract patients as the control group were included. The clinical features and laboratory parameters of all participants were collected and recorded, and the comprehensive index of inflammatory blood and its correlation with PVR were calculated. Results Monocytes and monocyte-to-high-density lipoprotein ratio (MHR) were significantly lower (P=0.005, P=0.044), while mean platelet volume (MPV), lymphocyte-to-monocyte ratio (LMR), and MPV-to-platelet ratio (MPR) were significantly higher in RRD patients as compared with the control group (P=0.013, P=0.019, P=0.037). LMR and MPR might be the predictors of RRD. The receiver operating characteristics analysis showed that the values of MPV, LMR, and MPR in RRD patients were 0.612, 0.606, and 0.594, respectively. PVR grade was not associated with inflammatory blood biomarkers. Conclusion The increase in MPV, LMR, and MPR were associated with increased odds of RRD. LMR and MPR may be useful as inexpensive and effortless biomarkers for assessing the occurrence of RRD.

Abstract
The etiopathogenesis of retinal vein occlusion (RVO) is multifactorial, and the contribution of platelets to RVO development has not been fully elucidated. We aimed to analyze platelet function in RVO patients (n = 35) and controls (n = 35). We found a higher (p < 0.05) level of soluble P-selectin in RVO group vs. controls. Additionally, in RVO patients, the concentration of platelet-derived microvesicles was higher (p < 0.05), and the difference between groups was deeper for the fraction of platelet-derived microvesicles with the procoagulant phenotype (p < 0.0001) and for overall procoagulant microvesicles level (p < 0.0001). The results were similar for the total RVO group and for both RVO types (central- and branched-retinal vein occlusion). We did not find differences in simple platelet parameters (platelet count, mean platelet volume, platelet distribution width, platecrit, reticulated platelets) and inflammatory markers (platelet-lymphocyte ratio, neutrophil-lymphocyte ratio). Similarly, no differences were found for platelet aggregation-stimulated byadenosine diphosphate; collagen; arachidonic acid; and in multiparametric flow cytometry evaluation of P-selectin, PAC-1, and fibrinogen binding for both unstimulated and adenosine diphosphate-, collagen-, and thrombin receptor activating peptide-stimulated platelets. Our results suggest that platelets can contribute to developing RVO by enhancing procoagulant activity through providing a procoagulation surface via platelet-derived microvesicles. The direct role of platelets’ hyperreactivity in developing RVO is less apparent, which is consistent with the complexity and multifactorial background of this disorder.

Abstract
AIM To develop a suitable radiation optic neuropathy (RON) diagnostic model based on optical coherence tomography angiography (OCTA) and to reveal the correlation between endocrine and OCTA indexes in nasopharyngeal carcinoma (NPC) patients with radiation encephalopathy (RE). METHODS This retrospective cross-sectional study included seventy-seven male NPC patients with RE following radiotherapy (41 non-RON and 36 RON). Endocrine and OCTA indexes were collected. The macular and peripapillary vessel density (VD) were automatically analyzed using AngioVue 2.0 of the RTVue XR Avanti device. The OCTA indexes were included in the multivariable binary logistic regression model between non-RON and RON. For all RE patients, a multiple linear regression was performed between each of the OCTA indexes and the endocrine indexes. RESULTS Compared to non-RON, enlarged foveal avascular zone (FAZ) area, reduced superficial vascular plexus (SVP) VD and radial peripapillary capillary plexus density, reduced full retinal thickness, ganglion cell complex thickness and peripapillary retinal nerve fiber layer thickness were observed in RON. Foveal VD in the SVP was included in the RON diagnostic model. Free triiodothyronine (FT3) showed a significantly negative correlation with the FAZ area but showed a significantly positive correlation with foveal VD in the SVP and deep vascular plexus, peripapillary VD and thickness and parafoveal and perifoveal thickness. CONCLUSIONS OCTA may be useful for diagnosing RON in male NPC patients with RE following radiotherapy. Reduced FT3 and foveal VD in SVP may be sensitive in screening RON in these patients.

Abstract
PURPOSE To assess the predictive value of inflammatory markers calculated from complete blood counts in patients with retinal vein occlusion (RVO). METHODS This was a retrospective cross-sectional study with a total of 56 RVO patients and 56 age- and gender-matched controls involved. All subjects went through a routine ocular examination, and the peripheral venous blood samples were collected to analyze the differences in inflammatory markers between groups. RESULTS The systemic immune-inflammation index (SII) and neutrophil-to-lymphocyte ratio (NLR) values were significantly higher in RVO patients than those in the controls (p=0.002, p=0.004, respectively). According to the receiver operating characteristic (ROC) curve analysis, the areas under the curve (AUC) of SII was 0.666. The AUC of NLR was 0.657. CONCLUSION As a novel inflammatory indicator, SII is a more promising indicator than NLR and PLR in the prediction of RVO development.

Abstract
Background: Chronic inflammation in type 2 diabetes mellitus (T2DM) is an essential contributor to the development of diabetic retinopathy (DR). The monocyte–to–high-density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel and simple measure related to inflammatory and oxidative stress status. However, little is known regarding the role of the MHR in evaluating the development of DR. Methods: A total of 771 patients with T2DM and 607 healthy controls were enrolled in this cross-sectional study. MHR determination and eye examination were performed. The association of MHR with the prevalence of DR in T2DM patients was analyzed. Results: The MHR in patients with DR was significantly higher than that in both non-DR diabetic patients (P < 0.05) and healthy controls (P < 0.01). No significance was observed in the MHR of different DR severity grades. Moreover, the MHR was similar between patients with non-macular oedema and those with macular oedema. Logistic regression analysis demonstrated that MHR was independently associated with the prevalence of DR in diabetic patients [odds ratio (OR) = 1.438, 95% confidence interval (CI): 1.249–1.655, P < 0.01]. After additional stratification by HbA1c level and diabetic duration, the MHR was still independently associated with the prevalence of DR. Conclusions: Our study suggests that the MHR can be used as a marker to indicate the prevalence of DR in patients with T2DM.

Abstract
Purpose: To investigate monocyte to high-density lipoprotein (HDL) ratio (MHR) and neutrophil-to-lymphocyte ratio (NLR) as indicators of systemic inflammation in acute central serous chorioretinopathy (CSC). Methods: The HDL levels, hematological profiles, erythrocyte sedimentation rates (ESR), and C-reactive protein (CRP) levels of 38 patients with acute CSC (Group I) and 38 controls without CSC (Group II) were measured. Results: MHRs were significantly higher in Group I (13.30 ± 2.95) than in Group II (11.52 ± 2.42, P = 0.005), whereas NLRs, CRP values, and ESR values did not significantly differ between the groups (P = 0.726, P = 0.219, and P = 0.441, respectively). Multivariate analysis revealed that the MHR was an independent predictor of acute CSC (OR = 1.266, 95% CI = 1.054-1.521, P = 0.012). Conclusion: Indicating an association between increased MHRs and acute CSC, the MHR might represent simple, inexpensive, reliable biomarkers of inflammation in acute CSC.

Abstract
OBJECTIVE To investigate the monocyte-to-HDL-cholesterol ratio (MHR), neutrophil to lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), eosinophil-to-lymphocytes ratio (ELR), platelet distribution width (PDW), red blood cell distribution width (RDW), mean platelet volume (MPV), MPV to platelet count ratio (MPV/PC), and RDW to platelet ratio (RPR) that are accepted as inflammatory markers in patients with keratoconus. METHODS In this study, 43 patients with keratoconus and 43 healthy individuals as the control group were retrospectively evaluated. High density lipoprotein cholesterol (HDL-c), lymphocyte, neutrophil, eosinophil, monocyte, platelet, MPV, PDW, and RDW values were obtained with complete blood count performed on the peripheral blood samples. RESULTS Absolute monocyte (593 ± 182 vs 492 ± 177; p < 0.05) and neutrophil (4860 ± 1553 vs 3954 ± 1297; p < 0.01) counts were statistically significantly higher in the keratoconus groups compared to the control group. MHR (13.18 ± 5.02 vs 9.88 ± 4.45; p < 0.01) and NLR (2.30 ± 0.87 vs 1.77 ± 0.61; p < 0.01) were statistically significantly higher and LMR (4.07 ± 1.67 vs 5.18 ± 2.06; p < 0.01) was significantly lower in the keratoconus group. As a result of univariate logistic regression analysis, it was observed that MHR and NLR were statistically significant relationship with keratoconus (p = 0.02 and p = 0.021) (Odds ratio = 5.41 (95% CI: 1.169-6.669) and Odds ratio:5.28 (95% CI: 1.024-6.321); respectively). No statistically significant difference was found between the groups in terms of PLR, ELR, RDW, MPV, PDW, MPV/PC, and RPR. Adjusting for age and gender, multivariate regression analysis revealed that MHR was the most significant parameter to demonstrate relationship with keratoconus (p = 0.025) (Odds ratio = 4.99 (95% CI: 1.019-6.332)). CONCLUSION MHR and NLR values considered as inflammatory markers were statistically significantly higher and LMR value was significantly lower in the keratoconus group. Among these values, MHR was the most reliable parameter.

Abstract
Purpose: To determine the association of monocyte-to-high-density lipoprotein ratio (MHR) and neutrophil-to-lymphocyte ratio (NLR) with diabetic macular edema (DME) and early anti-VEGF treatment response.Material methods: This was a retrospective and cross-sectional study conducted with 143 patients with diabetes mellitus (53 diabetic retinopathy with DME, 38 diabetic retinopathy without DME, and 52 without diabetic retinopathy).Results: 13.9 was the best cutoff value to predict DME for MHR, and 2 was for NLR (59% and 75% sensitivity and 81% and 59% specificity, respectively). Logistic regression analysis showed that NLR≥2 and MHR≥13.9 were significantly associated with DME prediction. However, neither NLR≥2 nor MHR≥13.9 was associated with central retinal thickness(CRT) or best corrected visual acuity(BCVA) outcomes after anti-VEGF treatment. On the other hand, increased NLR was associated with inferior CRT outcomes.Conclusion: MHR and NLR were simple and cost-effective biomarkers to predict DME. Moreover, higher NLR may contribute to poor CRT outcomes.

Abstract
PURPOSE Platelet count, mean platelet volume, platelet distribution width, and plateletcrit are standard indices of platelet activation that have been studied in retinal vein occlusion (RVO) and its subtypes: branch retinal vein occlusion and central retinal vein occlusion. This systematic review and meta-analysis aimed to assess the association between these platelet parameters and RVO. METHODS We searched for studies investigating the association between these platelet indices and RVO in multiple online databases from inception to August 2020. Mean differences and the associated confidence intervals were obtained and calculated for each included study and pooled using random-effects inverse variance modeling. Meta-regression was used to explore interstudy and intrastudy heterogeneity. RESULTS Thousand three hundred and twenty-five unique studies were screened, from which 24 studies encompassing 2,718 patients were included. Mean platelet volume and platelet distribution width were significantly elevated in RVO, with pooled mean differences of 0.45 fL (95% CI 0.24-0.66, P < 0.0001) and 1.43% (95% CI 0.57-2.29, P = 0.0011), respectively. Platelet count and plateletcrit were not significantly associated with RVO. Mean platelet volume was also independently elevated in branch retinal vein occlusion and central retinal vein occlusion. CONCLUSION Mean platelet volume and platelet distribution width are significantly elevated in RVO. Further research is required to explore the independence and potential prognostic significance of these associations.

Abstract
PURPOSE: The purpose of this study is to evaluate systemic inflammation in patients with pterygium using the monocyte-to-high-density lipoprotein cholesterol ratio (MHR) and hematologic indexes of inflammation. METHODS: Thirty-one patients with primary pterygium and 31 age-and sex-matched healthy participants were enrolled in this retrospective study. The MHR, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, eosinophil-to-lymphocyte ratio, monocyte-to-eosinophil ratio, mean platelet volume-to-platelet count ratio, platelet distribution width, and red cell distribution width were compared between the two groups. RESULTS: There was not a statistically significant difference in terms of the MHR between the pterygium group and the control group (P = 0.693). The NLR was higher in the pterygium group than in the control group (P = 0.028). In the other hematologic indexes, there were no statistically significant differences between the two groups (P > 0.05 for all). CONCLUSION: The MHR is not associated with the presence of pterygium. An increased NLR in patients with pterygium may be an indicator of systemic inflammation.

Abstract
PURPOSE To investigate the potential association between peripheral blood biomarkers and morphological characteristics of retinal imaging in patients with diabetic macular edema (DME). METHODS Participants in this cross-sectional study were 36 consecutive patients (36 eyes) with treatment-naïve DME, who underwent spectral domain-optical coherence tomography (SD-OCT), fundus photography, and fundus fluorescein angiography (FFA). In addition, peripheral blood samples were taken to evaluate full blood count and biochemical parameters. Correlation between imaging characteristics and laboratory parameters was examined. RESULTS Eyes with central subfield thickness greater than 405 μm presented significantly higher neutrophils/lymphocytes (p = 0.043) and higher lipoprotein (a) compared to eyes with CST < 405 μm (p = 0.003). Presence of hyperreflective foci on SD-OCT was associated with significantly higher white blood cell count (p = 0.028). Ellipsoid zone disruption was associated with significantly lower hematocrit (p = 0.012), hemoglobin (p = 0.009), and red blood cell count (p = 0.026), as well as with higher lipoprotein (a) (p = 0.015). Macular ischemia on FFA was associated with significantly higher monocytes (p = 0.027) and monocytes/HDL (p = 0.019). No significant associations were found between laboratory parameters and subretinal fluid, intraretinal fluid, exudates, cysts, disorganization of inner retinal layers, epiretinal membrane, and external limiting membrane condition. CONCLUSION Specific imaging morphological characteristics were found to be associated with laboratory parameters in patients with DME. These findings may shed light on the pathophysiology of DME and its correlation with the development of specific clinical signs.

Abstract
Background: Recently, considerable evidence pointed out monocyte to high-density lipoprotein ratio (MHR) is highly related to inflammatory related diseases. We aim to explore the level of MHR in acute aortic dissection (AAD) patients and determine whether MHR can be a novel diagnostic marker of AAD. Research design and methods: A total of 228 subjects including 128 AAD patients and 110 healthy control were enrolled. MHR levels and other serum samples were obtained at admission. Results: The baseline MHR levels were significantly higher in patients with AAD (p < 0.0001). A cutoff value of MHR >0.37 was associated with a sensitivity of 86.70% and a specificity of 93.60% for AAD. MHR levels were positively correlated with the time from symptom onset (R2 = 0.0318, p = 0.0003). Additionally, the area under the curve (AUC) was increased to 0.979 in patients whose time from onset of symptoms >24 h, with a sensitivity of 98.04% and a specificity of 93.64%. Multivariate logistic regression demonstrated that MHR levels, history of hypertension, and coronary artery disease (CHD) emerged as independent predictors of AAD. Expert Opinion: MHR has a high diagnostic value in AAD patients, especially in those whose time from onset of symptoms >24 h.

Abstract
Purpose. To evaluate the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio(PLR) value in the development of branch retinal vein occlusion (BRVO)patients. Methods. 81 patients with BRVO and 81 age and sex-matched subjects were recruited as the control group. The BRVO diagnosis was confirmed under comprehensive ophthalmologic examinations. NLR and PLR parameters obtained from peripheral blood were recorded. Results. Both the mean NLR and PLR was significantly higher in the BRVO group compared with the control group (p < 0.001). In ROC analysis, the AUC for NLR was 0.82, and NLR of >2.48 predicted BRVO with a sensitivity of 58% and specificity of 98%. The AUC for PLR was 0.78, and PLR of >110.2 predicted BRVO with a sensitivity of 72% and specificity of 72%. Conclusion. The current study demonstrated that BRVO patients had increased NLR and PLR levels compared with control subjects. The NLR and PLR may be used as independent predictors for identifying risk for the development of BRVO.
