RESUMO
AIM: To explore ocular surface manifestations of dry eye disease (DED) and its influencing factors in systemic lupus erythematosus (SLE) patients. METHODS: Ophthalmological examinations were conducted in SLE patients (n=43) and controls (n=41), including Ocular Surface Disease Index (OSDI), objective scatter index (OSI), tear meniscus height (TMH), lipid layer thickness (LLT), non-invasive Keratograph tear breakup time (NIKBUT), corneal fluorescein score (CFS), Schirmer I test. DED was diagnosed according to the Tear Film and Ocular Surface Society Dry Eye Workshop II Criteria. SLE patients were further divided into DED group and non-DED group, the disease activity, clinical manifestations and laboratory investigations were compared between the two groups. The disease activity was evaluated by Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K). Receiver operative characteristic (ROC) curve and multiple-factor binary logistic regression were performed. RESULTS: SLE patients showed higher OSDI [9.1 (2.8-15.9) vs 6.3 (2.2-7.5), P=0.035], higher OSI [1.67 (1.09-2.60) vs 0.96 (0.87-1.60), P=0.001], higher CFS [1 (0-2) vs 0 (0-1), P=0.001], lower LLT [65 (42-100) vs 100 (79.5-100), P=0.010], and lower NIKBUT [8.03 (4.02-9.73) vs 9.67 (5.26-12.71), P=0.030] than controls. The 32.6% of SLE patients had DED, which was higher than 12.2% of healthy controls. DED group showed higher SLEDAI-2K score [9.7±6.1 vs 5.4±3.4, P=0.025], higher anti-cardiolipin antibody (ACL) [8.7 (3.5-13.2) vs 3.6 (2.0-6.9), P=0.035], and higher proportion of patients with cutaneous eruption [42.9% vs 6.9%, P=0.015] than non-DED group. According to multiple-factor binary logistic regression analysis, the SLEDAI-2K score (OR=1.194, P=0.041) and cutaneous eruption (OR=7.094, P=0.045) could be consider as risk factors for DED in SLE patients. The ROC curve of the combined factors including age, disease duration, SLEDAI-2K score, ACL, and cutaneous eruption was analyzed, with a sensitivity of 0.786, a specificity of 0.793, and an area under curve of 0.820. CONCLUSION: Ocular surface affection is frequent in SLE patients, and patients with high disease activity and cutaneous eruption show increased risk of DED.
RESUMO
OBJECTIVE: To compare the postoperative recovery of primary pterygium excision combined with either limbal stem cell transplantation (LSCT) or amniotic membrane transplantation (AMT). METHODS: All relevant studies on the primary pterygium excision combined with either LSCT or AMT conducted before August 2022 were extracted from PubMed, EMBASE, Web of Science, and Cochrane Library databases. The main outcomes compared were tear film stability at 1, 3, and 6 months after surgery, postoperative corneal epithelial healing time, recurrence rate, and complications. RESULTS: Sixteen randomized controlled trials (RCTs) with 1390 eye cases were included in this meta-analysis. We found that patients of the AMT group improved significantly in the results of the tear break-up time (BUT) and Schirmer I test at 1 month after surgery (BUT: MD=-0.37, 95% CI: -0.62, -0.12, P<0.05; Schirmer I test: MD=-0.32, 95% CI: -0.57, -0.07, P<0.05) compared with those of the LSCT group, suggesting that the early stage of tear film stability after primary pterygium excision combined with AMT was superior to the LSCT combination. However, according to the Schirmer I test result, the patients in the LSCT group showed increased tear production compared to the AMT group at 3 and 6 months after surgery (3 months: MD=0.36, 95% CI: 0.08, 0.64, P<0.05; 6 months: MD=0.33, 95% CI: 0.07, 0.60, P<0.05), suggesting that the LSCT combination was superior to the AMT combination in long-term postoperative tear film stability. As for postoperative corneal epithelial healing time, the LSCT group exhibited shorter time than the AMT group (MD=-1.17, 95% CI: -2.15, -0.19, P<0.05). Furthermore, the recurrence rate was lower in the LSCT group than in the AMT group (RR=0.42, 95% CI: 0.30, 0.59, P<0.05). Lastly, there was no statistical difference in BUT and complication rate at 3 and 6 months after surgery between the LSCT and AMT groups. CONCLUSIONS: Our analysis suggests that primary pterygium excision combined with LSCT may be a better choice compared to the combination with AMT in postoperative recovery.
