ABSTRACT
Objectives Anticardiolipin antibody (aCL) is an important component of antiphospholipid antibody (aPL) and a marker antibody of antiphospholipid syndrome (aPS). APL is positive in 20% to 40% of patients with systemic lupus erythematosus(SLE). This article investigated the clinical features and prognosis of SLE patients with aCL. Methods From January 1999 to December 2009, 495 cases of SLE patients detected aCL who were hospitalized for the first time in 26 hospitals in Jiangsu Province including Nanjing Drum Tower Hospital were divided into aCL-positive group and aCL-negative group according to the test results. The patients were followed up in survival status, and the demographic characteristics, affected organs, laboratory tests, treatment drugs, and prognosis were compared between two groups. Results 146 of the SLE patients in this group were positive for aCL. The proportion of women in aCL- positive group (96.6%) was significantly higher than that in aCL-negative group (90.8%), and the difference was statistically significant (P<0.05). The proportion of anemia (74.7% vs 61.3%), decreased C3(81.5% vs 71.1%), positive antinuclear antibody(97.2% vs 92.4%), and positive anti-dsDNA antibody (61.9% vs 49.6%) in aCL-positive group were significantly higher than those of aCL-negative group, and the difference was statistically significant (P<0.05). The aCL-positive group received a higher proportion of cyclophosphamide immunosuppressive therapy (39.5% vs 50.7%, P<0.05). At the end of follow-up, the mortality rate of aCL-positive group was 13.7%, and the mortality rate of aCL-negative group was 14.9% and there was no significant difference in mortality (P>0.05). Kaplan-Meier survival analysis showed that the 1-year, 5-year, and 10-year survival rates of aCL-positive group were 94.5%, 89.0%, and 82.9%, respectively, and there was no significant difference compared with aCL-negative group(P=0.776). The main causes of death in aCL-positive group were lupus encephalopathy (6 cases, 30.0%), renal failure (5 cases, 25.0%), heart failure (4 cases, 20.0%) and infection (3 cases, 15%). The main causes of death in aCL-negative group were infection (21 cases, 40.4%), lupus encephalopathy (11 cases, 21.2%) and heart failure (5 cases, 9.6%) and renal failure (4 cases, 7.7%). Conclusion SLE patients with aCL represent a high propotion in anemia, decreased C3, positive antinuclear antibody, positive anti-dsDNA antibody. There was no significant difference in disease activity and significant organ involvement between two groups. More SLE patients with aCL were treated with cyclophosphamide, and there was no significant difference in survival status between SLE patients with and without aCL during long-term follow-up.
ABSTRACT
AIM: To investigate the effects of vitrectomy combined with cataract surgery on the corneal endothelial cells in diabetic retinopathy.METHODS: A retrospective study was designed.160 patients(160 eyes) with diabetic retinopathy from Jan 2015 to Feb 2017 were divided into two groups according to cataract.74 patients(74 eyes) were operated on vitrectomy,and 86 patients(86 eyes) on vitrectomy combined with phacoemulsification cataract surgery and capsular bag implantation of foldable intraocular lens.To record the change of corneal endothelial cells density,average cellular area,coefficient of variation and percentage of hexagonal endothelial cell before and after treatment with Topcon corneal specular microscope.RESULTS: Before and after surgery,the results of corneal endothelial cells density,average cellular area,coefficient of variation and percentage of hexagonal endothelial cell in simple vitrectomy group were no significant difference(P>0.05);After treatment corneal endothelial cells density and percentage of hexagonal endothelial cell were changed with statistical difference as the same as average cellular area and coefficient of variation(P<0.05);There were significantly differences in corneal endothelial cells between two groups(P<0.05).CONCLUSION: It has certain influence on the corned endothelial cells when using vitrectomy combined with cataract surgery in diabetic retinopathy.For patients with indications,it should be paid attention to protecting the corneal endothelial cells.
