RESUMO
OBJECTIVES: This study was designed to assess the monocyte-to-high-density lipoprotein (HDL) ratio (MHR) as a possible marker of systemic inflammation in patients with branch retinal vein occlusion (BRVO). METHODS: A study group of 62 patients with BRVO and a control group of 60 age-matched, healthy individuals were enrolled in the study. The blood lipid profile, hematology profile, and C-reactive protein (CRP) level were measured. The MHR was calculated as the ratio of the monocyte count to the HDL level, and the neutrophil-to-lymphocyte ratio (NLR) was calculated as the ratio of the neutrophil count to the lymphocyte count. RESULTS: In patients with BRVO versus controls, the mean MHR was 14.1±5.1 vs 12.2±4.3 (p=.032), the mean NLR was 1.99±0.69 vs 2.01±0.86 (p=.889), and the mean CRP level was 3.44±2.53 mg/L vs 2.81±1.57 mg/L (p=.102). The area under the receiver operating characteristic curve for the MHR and the NLR was 0.621 and 0.519, respectively. The sensitivity and specificity of the MHR and the NLR to predict BRVO was 51% and 73% vs 79% and 35%, respectively. CONCLUSION: The MHR values were higher in patients with BRVO compared with those of the control group. BRVO seems to be associated with systemic inflammation.
RESUMO
PURPOSE: Psychiatric conditions and not just the treatments themselves might be involved in the pathophysiology of dry eye disease (DED). The aim of our study was to evaluate the association between depression and DED using objective and subjective tests in patients with newly diagnosed depressive disorder who were not using any medication which may help us to determine the sole effect of depression on dry eye. METHODS: Thirty-six patients from the psychiatry clinic with a new diagnosis of depressive disorder and 32 controls were included in the study. All met the Diagnostic and Statistical Manual IV criteria for depression. Beck Depression Inventory (BDI) was used to measure depression severity and the State-Trait Anxiety Inventory (Stai1, Stai2) for concomitant anxiety symptoms. The Ocular Surface Disease Index (OSDI) and Visual Functioning Questionnaires (VFQ25) were completed and used to confirm diagnosis of DED in conjunction with the tear break up time (TBUT), ocular surface vital dye staining, and Schirmer's test. RESULTS: The comparison of depressive and control groups revealed significantly lower Schirmer (20.3 ± 9.9 vs. 25.7 ± 9.3 mm) and TBUT (7.8 ± 5.7 vs. 12.5 ± 7.8 s) scores with a consistently higher Oxford score (1.8 ± 3.2 vs. 0.2 ± 0.4) in the depressive group. Although the parameters were affected in the depressive group, this did not influence OSDI (86.1 ± 13.6 vs. 86.6 ± 13.3) and VFQ25 (30.8 ± 21.6 vs. 38.5 ± 29.1) scores. In both groups, the three psychological test scores (Stai1-2 and BDI) were correlated to each other but none of these tests were correlated to OSDI, VRQL, Schirmer, TBUT, and Oxford staining scores. CONCLUSION: Our study shows a definite association between depression and DED. We feel that it is important that psychiatrists take this into account especially while prescribing antidepressants which may aggravate dry eye signs.
