[PMID: 31882462 DOI: 10.21873/invivo.11744] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2019] [Revised: 10/05/2019] [Accepted: 10/10/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND/AIM In literature, few studies have examined the diagnostic or prognostic potential of matrix metalloproteinases (MMP) in pterygium, whose formation and progression are closely related to imbalance in the extracellular microenvironment. In this study, we investigated the contribution of MMP7 promoter (A-181G and C-153T) polymorphic genotypes to pterygium risk. MATERIALS AND METHODS A total of 134 cases and 268 controls were collected and their MMP7 genotypes at A-181G and C-153T were examined by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The AA, AG and GG genotypes at MMP7 promoter A-181G were non-significantly differentially distributed between the two groups at 85.8, 11.2 and 3.0%, respectively, in pterygium cases and 88.4, 9.7 and 1.9% in controls, respectively (p for trend=0.6822). There was no polymorphic genotype for MMP7 C-153T among our Taiwanese cohort. CONCLUSION A-181G and C-153T genotypes at MMP7 do not have a direct role in determining Taiwanese susceptibility to pterygium.

Evaluation of Neutrophil-Lymphocyte Ratios, Mean Platelet Volumes, and Platelet-Lymphocyte Ratios in Pterygium. BEYOGLU EYE JOURNAL 2019; 4:163-167. [PMID: 35187453 PMCID: PMC8842070 DOI: 10.14744/bej.2019.30164] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/22/2019] [Accepted: 09/15/2019] [Indexed: 11/29/2022]
Abstract
Objectives: To assess the neutrophil-to-lymphocyte ratio (NLR), mean platelet volumes (MPV), platelet–lymphocyte ratios (PLR) and other complete blood count parameters (CBC) as indicators of inflammation in patients with pterygium. Methods: This study was carried out retrospectively in 111 consecutive pterygium patients and 106 control subjects. Laboratory and clinical parameters were obtained from the patient data management system. NLR and PLR were calculated by dividing neutrophil and platelet count by lymphocyte count. Results: A significant difference was found in NLR and lymphocyte values between the pterygium and control groups (p<0.05). However, there was no significant difference found in MPV, PLR and other parameters between groups (p>0.05). Conclusion: NLR may have an association with pterygium, which should be investigated at larger subgroups in further studies.
