BACKGROUND: Post-transplant diabetes mellitus (PTDM) is a relatively common complication of kidney transplantation. The aim of our work was to compare the incidence of PTDM in kidney transplant recipients with and without autosomal dominant polycystic kidney disease (ADPKD) in a matched-pair design study. METHODS: In total, 98 pairs of graft recipients, all of Caucasian origin and who received a kidney from the same cadaveric donor, were included in the study. The following clinical data were collected for statistical analysis: age, body mass index (BMI) before transplant, length and type of dialysis treatment, residual diuresis, and cold and warm graft ischemia time. Diabetes was diagnosed based on American Diabetes Association (ADA) criteria. RESULTS: Incidence of PTDM was 19.4% in the ADPKD group and 18.4% in the non-ADPKD group, with no significant differences between groups. Multivariate logistic regression analysis of the PTDM risk in the ADPKD group including age, gender, BMI, and dialysis time as independent variables indicated that only higher residual diuresis is a significant independent risk factor (OR = 5.64 per every L/24 h, 95% CI = 1.31-24.33, p = 0.017). Similarly, logistic regression analysis adjusted for age and gender in the non-ADPKD group has shown that significant independent risk factors are BMI (OR = 1.30 per every kg/m(2), 95% CI = 1.06-1.59, p = 0.0094), longer dialysis time prior to transplant (OR = 1.036 per each month, 95% CI = 1.004-1.070, p = 0.025), and a history of arterial hypertension (OR = 9.09, 95% CI = 1.20-68.66, p = 0.030). CONCLUSIONS: In this paired analysis, our results suggest that diagnosis of ADPKD does not increase risk of PTDM. 相似文献

CONTEXT: Diabetic ketoacidosis and severe hypoglycemia are acute complications of type 1 diabetes that are related, respectively, to insufficient or excessive insulin treatment. However, little is known about additional modifiable risk factors. OBJECTIVE: To examine the incidence of ketoacidosis and severe hypoglycemia in children with diabetes and to determine the factors that predict these complications. DESIGN, SETTING, AND PARTICIPANTS: A cohort of 1243 children from infancy to age 19 years with type 1 diabetes who resided in the Denver, Colo, metropolitan area were followed up prospectively for 3994 person-years from January 1, 1996, through December 31, 2000. MAIN OUTCOME MEASURES: Incidence of ketoacidosis leading to hospital admission or emergency department visit and severe hypoglycemia (loss of consciousness, seizure, or hospital admission or emergency department visit). RESULTS: The incidence of ketoacidosis was 8 per 100 person-years and increased with age in girls (4 per 100 person-years in < 7; 8 in 7-12; and 12 in > or =13 years; P<.001 for trend). In multivariate analyses, sex-adjusted and stratified by age (<13 vs > or =13 years), the risk of ketoacidosis in younger children increased with higher hemoglobin A(1c) (HbA(1c)) (relative risk [RR], 1.68 per 1% increase; 95% confidence interval [CI], 1.45-1.94) and higher reported insulin dose (RR, 1.40 per 0.2 U/kg per day; 95% CI, 1.20-1.64). In older children, the risk of ketoacidosis increased with higher HbA(1c) (RR, 1.43; 95% CI, 1.30-1.58), higher reported insulin dose (RR, 1.13; 95% CI, 1.02-1.25), underinsurance (RR, 2.18; 95% CI, 1.65-2.95), and presence of psychiatric disorders (for boys, RR, 1.59; 95% CI, 0.96-2.65; for girls, RR, 3.22; 95% CI, 2.25-4.61). The incidence of severe hypoglycemia was 19 per 100 person-years (P<.001 for trend) and decreased with age in girls (24 per 100 patient-years in < 7, 19 in 7-12, and 14 in > or =13 years). In younger children, the risk of severe hypoglycemia increased with diabetes duration (RR, 1.39 per 5 years; 95% CI, 1.16-1.69) and underinsurance (RR, 1.33; 95% CI, 1.08-1.65). In older children, the risk of severe hypoglycemia increased with duration (RR, 1.34; 95% CI, 1.25-1.51), underinsurance (RR, 1.42; 95% CI, 1.11-1.81), lower HbA(1c) (RR, 1.22; 95% CI, 1.12-1.32), and presence of psychiatric disorders (RR, 1.56; 95% CI, 1.23-1.98). Eighty percent of episodes occurred among the 20% of children who had recurrent events. CONCLUSIONS: Some children with diabetes remain at high risk for ketoacidosis and severe hypoglycemia. Age- and sex-specific incidence patterns suggest that ketoacidosis is a challenge in adolescent girls while severe hypoglycemia continues to affect disproportionally the youngest patients and boys of all ages. The pattern of modifiable risk factors indicates that underinsured children and those with psychiatric disorders or at the extremes of the HbA(1c) distribution should be targeted for specific interventions. 相似文献

BACKGROUND: Cardiovascular (CV) risk factors are influenced by behavioral, cultural, and social factors, suggesting that acculturation plays a significant role in the emergency and growth of chronic disease. The objective of this study was to determine the relation between CV risk factors and the main components of acculturation, in Yaquis and Tepehuanos Indians from Mexico. METHODS: This was a cross-sectional population-based study in Yaquis and Tepehuanos communities from the Yaqui Valley in Sonora and the Sierra Madre Occidental Mountains in Durango, in northwest Mexico. Acculturation status is different in both ethnic groups, with Tepehuanos living in small and remote communities retaining their traditional lifestyle and Yaquis living in well-communicated communities that have assumed Westernized lifestyles. RESULTS: A total of 278 indigenous (120 Tepehuanos and 158 Yaquis) were randomly enrolled. Prevalence of obesity (48.1 and 6.7%, p <0.001), diabetes (18.3 and 0.83%, p <0.001), hypertriglyceridemia (43.0 and 15.0%, p <0.001), alcohol consumption (46.8 and 26.6%, p >0.001), and smoking (29.7 and 15.0%, p = 0.006) were significantly higher in Yaquis Indians. High blood pressure (6.3 and 3.3%, p = 0.40) and low HDL-cholesterol (42.4 and 34.2%, p = 0.22) were similar between Yaquis and Tepehuanos. Multivariate regression analysis adjusted by sex and age showed a significant association between calorie intake from saturated fat, but not other nutrients of customary diet, with hyperglycemia (OR 7.4, 95% CI 2.6-20.1), hypertriglyceridemia (OR 3.1, 95% CI 1.5-6.3), and obesity (OR 3.4, 95% CI 1.6-10.1). CONCLUSIONS: Among the components of acculturation, intake of saturated fat is the most strongly associated with the development of CV risk factors. 相似文献

伴急性/亚急性间质性肺炎的临床无肌炎皮肌炎1年生存随访及危险因素分析 总被引:1,自引:0,他引:1
目的 了解伴发急性/亚急性间质性肺炎的临床无肌炎皮肌炎患者在不同治疗方案干预后1年的生存状况,并分析其危险因素.方法 回顾性分析上海交通大学医学院附属仁济医院风湿科于1998年1月-2007年12月收治的伴发急性/亚急性间质性肺炎的成人临床无肌炎皮肌炎患者51例,追踪1年时的生存情况,采用Kaplan-Meier法比较不同治疗方案干预后1年的生存曲线,以COX回归分析该组患者的危险因素.结果 Kaplan-Meier生存分析显示,联合激素+免疫抑制剂方案(95%CI值为8.10~10.69)优于单纯激素治疗方案(95%CI值为1.03~4.57,P<0.001).与硫唑嘌呤+激素治疗方案(95%CI值为4.49~10.11)相比,应用环孢素+激素治疗方案的生存时间显著延长(95%CI值为8.27~12.66,P=0.045).通过COX回归分析,筛选到的危险因素分别是治疗方案未联合使用免疫抑制剂(RR=2.73,P=0.001),间质性肺炎为急性型(RR=3.10,P=0.020),以及治疗初始已出现低氧血症(RR=6.17,P=0.005).结论 在现有各种药物治疗干预下伴急性/亚急性间质性肺炎的临床无肌炎皮肌炎预后仍不乐观,间质性肺炎的类型固然是预后的决定因素之一,但早期用药、联合激素与免疫抑制剂治疗能延长患者的生存时间,其中联合环孢素的治疗方案更佳. 相似文献

Living donor liver transplantation (LDLT) has become one of the chief methods of saving patients with end-stage liver disease due to liver cirrhosis. Accumulation of knowledge about indication and perioperative managements improve outcome of this treatment. In this study, we elucidate the risk factors of LDLT, which still exist today. Sixty-one patients received LDLT in our institute between 2003 and 2009 were included in this study. Recipient age and sex, donor age and sex, etiology, preoperative model of end-stage liver disease (MELD) score, hepatocellular carcinoma (HCC), graft versus recipient weight ratio (GRWR), cold and warm ischemic time, operation time, blood loss, ABO compatibility, rejection, cytomegalovirus (CMV) infection, biliary stricture, and calcineurin inhibitor (FK506 or cyclosporin A) were the factors investigated. p < 0.05 was considered as statistically significant in the proportional hazard model. In univariate analysis, the recipients' age (p = 0.024) and rejection episode (p = 0.046) were selected as significant risk factors. In multivariate analysis including the factors that showed p < 0.2 (recipient age, GRWR, ABO compatibility, rejection episode) in univariate analysis, recipient age (p = 0.008, HR: 1.40; 95% CI: 1.09-1.80) and rejection episodes (p = 0.002, HR: 13.33; 95% CI: 2.53-71.43) were still selected as significant independent risk factors after LDLT. Recipient age was shown to be 1.40 times risk per 1 year older and the rejection episode was shown to be 13.33 times risk in the recent era with comprehensive indication and preoperative management for LDLT. Indication must be cautious for elderly patients, and prevention of rejection is crucial for the improvement of results for LDLT. 相似文献

Objective
Due to organ shortage, average waiting time for a kidney in Germany is about 4 years after start of dialysis. Number of kidney grafts recovered can only be maintained by accepting older and expanded criteria donors. The aim of this study was to analyse the impact of donor and recipient risk on kidney long-term function.Methods
All deceased kidney transplantations were considered. We retrospectively studied 332 patients between 2002 and 2006; divided in 4 groups reflecting donor and recipient risk.Results
Non-marginal recipients were less likely to receive a marginal organ (69 of 207, 33%) as compared to marginal recipients, of whom two-thirds received a marginal organ (p < 0.0001). Graft function significantly differed between the groups, but detrimental effect of marginal recipient status on eGFR after 12 months (-6 ml/min/1.73 qm, 95% CI -2 to -9) was clearly smaller than the effect of marginal donor status (-10 ml/min/1.73 qm, 95% CI -7 to -14).Conclusions
As we were able to show expanded criteria donor has a far bigger effect on long-term graft function than the "extra risk" recipient. Although there have been attempts to define groups of recipients who should be offered ECD kidneys primarily the discussion is still ongoing. 相似文献14.

Objective
To assess the efficacy and safety of Aidi injection plus transarterial chemoembolization (TACE) in patients with primary hepatic carcinoma.Methods
A comprehensive research of seven electronic databases was performed for comparative studies evaluating Aidi injection combined with TACE for primary hepatic carcinoma until September 2016. Two authors independently extracted data and assessed the methodological quality of the included trials using the Cochrane risk of bias tool from the Cochrane Handbook version 5.1.0. Data was synthesized by using RevMan 5.3 software.Results
Forty-nine studies involving 3435 patients met the inclusion criteria, most of which were low methodological quality. Compared with TACE alone, Aidi injection plus TACE can significantly improve the efficiency rate [RR = 1.33, 95%CI (1.24, 1.43), P < 0.000 01], clinical beneficial rate [RR = 1.25, 95% CI (1.17, 1.33), P < 0.000 01], survival rate [6 months, RR = 1.19, 95% CI (1.09, 1.29), P < 0.0001], 12 months, [RR = 1.37, 95% CI (1.24, 1.52), P < 0.000 01], 18 months, [RR = 2.00, 95% CI (1.26, 3.20), P < 0.004], 24 months, [RR = 1.44, 95% CI (1.22, 1.70), P < 0.0001], 36 months, [RR = 1.50, 95% CI (1.07, 2.11), P = 0.02 < 0.05], quality of life [RR = 1.84, 95% CI (1.64,2.05), P < 0.000 01] and immune function [CD3+, MD = 11.12, 95% CI (7.93, 14.30), P < 0.000 01], CD4+, [MD = 10.37, 95% CI (7.29, 13.45), P < 0.000 01], CD4+/CD8+, [MD = 0.30, 95% CI (0.07,0.53), P = 0.01 < 0.05], NK, [MD = 7.49, 95% CI (6.64,8.34), P < 0.000 01]. A significant improvement was also found in improvement of symptoms [RR = 1.64, 95%CI (1.38, 1.94), P < 0.000 01], leukopenia [RR = 0.60, 95% CI (0.54,0.66), P < 0.000 01], thrombocytopenia [RR = 0.46, 95% CI (0.34,0.61), P < 0.000 01], nausea and vomiting incidence [RR = 0.66, 95% CI (0.54, 0.81), P < 0.0001), liver damage rate [RR = 0.57, 95% CI (0.42, 0.77), P = 0.0003 < 0.05), and kidney damage rate [RR = 0.18, 95% CI (0.05, 0.68), P = 0.01 < 0.05].Conclusion
The results suggested that Aidi injection plus TACE significantly improve the clinical effect of TACE, and reduce the incidence of adverse events. However, rigorous multicenter trials with larger size are warranted to further confirm the findings. 相似文献15.

Background The definite pathogenesis of hemorrhagic cystitis (HC) after allogenic hematopoietic stem cell transplantation (allo-HSCT) has not been well elucidated. The role of cytomegalovirus (CMV) reactivation and graft-versus-host disease (GVHD) in the development of HC remains obscure. This study determined the incidence and risk factors for HC after allo-HSCT and analyzed its association with CMV reactivation and GVHD.Methods We retrospectively studied 250 patients at high risk for CMV disease who underwent allo-HSCT all based on busulfan/cyclophosphamide (BU/CY) myloablative regimens. The incidence, etiology, risk factors and clinical management of HC were investigated. Results HC developed within 180 days of transplant in 72 patients, with an overall incidence of 28.8% and an incidence of 12.6% in patients with HLA-matched related donors (MRD), 34.38% in those with HLA-matched unrelated donors (MUD), 49.45% in those with mismatched related donors (MMRD). CMV-viremia significantly increased the incidence of later onset HC (LOHC); however, only 9 out of 15 patients with CMV viruria actually developed LOHC. Multiple regression analysis identified grade II–IV acute GVHD (RR=2.75; 95% CI 1.63–4.66; P<0.01) and grafts from MUD or MMRD (RR=2.60; 95% CI 1.52–5.20; P<0.01) as independent risk factors for HC. Event sequence analysis indicated a majority of HC episodes began around GVHD initiation.Conclusions CMV-viremia is a high risk factor for LOHC. Our data also showed a correlation between acute GVHD and HC, which suggested that alloimmunity may be involved in the pathogenesis of HC. 相似文献

Methods The databases of Medline, EMBASE, Elsevier, Cochrane library, Wanfang and CNKI were searched for randomized controlled trials. Quality assessment and data extraction were performed by two independent reviewers. Statistical analyses were conducted with Stata 10.0 and RevMan 5.0 software. Results Eight studies (NORDI-STEMI, TRANSFER-AMI, WEST, CARESS-AMI, CAPITAL-AMI, GRACIA-Ⅰ, SIAMI Ⅲ & PRAGUE-Ⅰ) involving a total of 3157 patients fulfilled the inclusion criteria. Meta-analysis results showed that, as compared with the control group, (1) the combined endpoint of 30 day mortality, re-infarction and ischemia was significantly lower in early PCI within 24 h of thrombolysis group [relative risk (RR)=0.52, 95% confidence interval (CI)0.42-0.65, P<0.001]; (2) 30-day re-infarction decreased in early PCI within 24 h of thrombolysis group (RR=0.57, 95% CI 0.40-0.81, P=0.002); (3) 30-day ischemia had a significant reduction in early PCI within 24 h of thrombolysis group (RR=0.27, 95% CI 0.14-0.52, P<0.001); (4) 30-day major hemorrhage or mortality rates were not significantly different between two groups (RR=1.07, 95% CI 0.78-1.46, P=0.69; RR=0.86, 95% CI 0.62-1.20, P=0.38 respectively). Conclusion When primary PCI is not feasible, our meta-analysis favors early PCI within 24 h of thrombolysis for acute ST-elevation myocardial infarction. Early PCI is associated with a lowered recurrence of major adverse cardiac events, ischemia and re-infarction. But there is no elevated risk of major hemorrhage and mortality. 相似文献

Coagulase-negative staphylococcus and enterococcus as predominant pathogens in liver transplant recipients with Gram-positive coccal bacteremia 总被引:2,自引:0,他引:2
SHI Shao-hua KONG Hai-shen JIA Chang-ku XU Jian ZHANG Wen-jin WANG Wei-lin SHEN Yan ZHANG Min ZHENG Shu-sen 《中华医学杂志(英文版)》2010,123(15):1983-1988
Background Gram-positive bacteria such as Staphylococcus aureus have been a common cause of infection among liver transplant (LT) recipients in recent decades. The understanding of local epidemiology and its evolving trends with regard to pathogenic spectra and antibiotic susceptibility is beneficial to prophylactic and empiric treatment for LT recipients. This study aimed to investigate etiology, timing, antibiotic susceptibility and risk factors for multidrug resistant (MDR) Gram-positive coccal bacteremia after LT.Methods A cohort analysis of prospectively recorded data was performed to investigate etiologies, timing, antibiotic susceptibility and risk factors for MDR Gram-positive coccal bacteremia in 475 LT recipients.Results In 475 LT recipients in the first six months after LT, there were a total of 98 episodes of bacteremia caused by Gram-positive cocci in 82 (17%) patients. Seventy-five (77%) bacteremic episodes occurred in the first post-LT month.The most frequent Gram-positive cocci were methicillin-resistant coagulase-negative staphylococcus (CoNS, 46 isolates),methicillin-resistant Staphylococcus aureus (MRSA, 13) and enterococcus (34, E. faecium 30, E. faecalis 4). In all Gram-positive bacteremic isolates, 59 of 98 (60%) were MDR. Gram-positive coccal bacteremia and MDR Gram-positive coccal bacteremia predominantly occurred in patients with acute severe exacerbation of chronic hepatitis B and with fulminant/subfulminant hepatitis. Four independent risk factors for development of bacteremia caused by MDR Gram-positive coccus were: LT candidates with encephalopathy grades Ⅱ-Ⅳ (P=0.013, OR: 16.253, 95% CI:1.822-144.995), pre-LT use of empirical antibiotics (P=0.018, OR: 1.029, 95% CI: 1.002-1.057), post-LT urinary tract infections (P 〈0.001, OR: 20.340, 95% CI: 4.135-100.048) and abdominal infection (P=0.004, OR: 2.820, 95% CI:1.122-10.114). The main infectious manifestations were coinfections due to gram-positive cocci and gram-negative bacilli.Conclusions Methicillin-resistant CoNS and enterococci are predominant pathogens among LT recipients with Gram-positive coccal bacteremia. Occurrences of Gram-positive coccal bacteremia may be associated with the severity of illness in the perioperative stage. 相似文献

CONTEXT: Microalbuminuria is a risk factor for cardiovascular (CV) events. The relationship between the degree of albuminuria and CV risk is unclear. OBJECTIVES: To estimate the risk of CV events in high-risk individuals with diabetes mellitus (DM) and without DM who have microalbuminuria and to determine whether levels of albuminuria below the microalbuminuria threshold increase CV risk. DESIGN: The Heart Outcomes Prevention Evaluation study, a cohort study conducted between 1994 and 1999 with a median 4.5 years of follow-up. SETTING: Community and academic practices in North and South America and Europe. PARTICIPANTS: Individuals aged 55 years or more with a history of CV disease (n = 5545) or DM and at least 1 CV risk factor (n = 3498) and a baseline urine albumin/creatinine ratio (ACR) measurement. MAIN OUTCOME MEASURES: Cardiovascular events (myocardial infarction, stroke, or CV death); all-cause death; and hospitalization for congestive heart failure. RESULTS: Microalbuminuria was detected in 1140 (32.6%) of those with DM and 823 (14.8%) of those without DM at baseline. Microalbuminuria increased the adjusted relative risk (RR) of major CV events (RR, 1.83; 95% confidence interval [CI], 1.64-2.05), all-cause death (RR, 2.09; 95% CI, 1.84-2.38), and hospitalization for congestive heart failure (RR, 3.23; 95% CI, 2.54-4.10). Similar RRs were seen for participants with or without DM, even after adjusting for other CV risk factors (eg, the adjusted RR of the primary aggregate end point was 1.97 [95% CI, 1.68-2.31] in those with DM and 1.61 [95% CI, 1.36-1.90] in those without DM).Compared with the lowest quartile of ACR (<0.22 mg/mmol), the RRs of the primary aggregate end point in the second quartile (ie, ACR range, 0.22-0.57 mg/mmol) was 1.11 (95% CI, 0.95-1.30); third quartile, 1.38 (95% CI, 1.19-1.60; ACR range, 0.58-1.62 mg/mmol); and fourth quartile, 1.97 (95% CI, 1.73-2.25; ACR range, >1.62 mg/mmol) (P for trend <.001, even after excluding those with microalbuminuria). For every 0.4-mg/mmol increase in ACR level, the adjusted hazard of major CV events increased by 5.9% (95% CI, 4.9%-7.0%). CONCLUSIONS: Our results indicate that any degree of albuminuria is a risk factor for CV events in individuals with or without DM; the risk increases with the ACR, starting well below the microalbuminuria cutoff. Screening for albuminuria identifies people at high risk for CV events. 相似文献

Polymorphisms in cytokine genes and their association with acute rejection and recurrence of hepatitis B in Chinese liver transplant recipients 总被引:1,自引:0,他引:1
Xie HY Wang WL Yao MY Yu SF Feng XN Jin J Jiang ZJ Wu LM Zheng SS 《Archives of medical research》2008,39(4):420-428
BACKGROUND: Acute rejection (AR) and hepatitis B virus (HBV) recurrence after liver transplantation (LT) are the two major complications leading to chronic graft dysfunction. Genomic polymorphisms in interleukin (IL)-10, tumor necrosis factor (TNF)alpha and transforming growth factor (TGF)beta1 genes have been found to affect the susceptibility to certain diseases. However, the relationship between cytokine gene polymorphisms and risk of AR as well as HBV recurrence after LT in Han Chinese has not been reported. The objective of the present study was to investigate the association of polymorphisms within these cytokine genes with the risk of AR as well as HBV recurrence. METHODS: One hundred eighty six Chinese LT recipients in which 41 patients developed AR and 29 patients experienced HBV recurrence were enrolled; 151 age- and gender-matched healthy individuals were selected as controls. Single-nucleotide polymorphisms (SNPs) at loci of IL-10 -1082, -819, -592, and TNFalpha -308, -238, as well as TGFbeta1 -988, -800, -509, +869, and +915 were determined by using DNA sequencing and then confirmed by restriction fragment length polymorphism (PCR-RFLP). Analyses of linkage disequilibrium and haplotype frequency were performed using Haploview program. RESULTS: The -819 and -592 polymorphisms in the IL-10 gene were in complete linkage (r(2) = 1). Another linkage was found at -509 and +869 in the TGFbeta1 gene (r(2) = 0.66). A significant difference was observed in the distribution of allelic frequencies at position -819 and -592 in the IL-10 gene between ARs and non-ARs (p = 0.036, OR = 1.134, 95% CI 0.999-1.287 and p = 0.036, OR = 1.134, 95% CI 0.999-1.287, respectively). After adjustment for a Bonferroni correction, there was no significant difference between the polymorphism and AR (p >0.05). Furthermore, the overall genotype distribution between HBV recurrence patients and non-HBV recurrence patients was also not significantly different (p >0.05). CONCLUSIONS: Our study suggests that gene polymorphisms of IL10, TNFalpha, and TGFbeta1 do not have a major independent role in AR and HBV recurrence after LT and may not be risk factors of AR and HBV recurrence after LT in Chinese liver transplant recipients. 相似文献

Efficacy and tolerability of one-site versus two-site phaco- trabeculectomy: a meta-analysis of randomized controlled clinical trials 总被引:1,自引:0,他引:1
Background Phacotrabeculectomy can be performed using one-site or two-site incisions.This meta-analysis evaluated the efficacy and tolerability of one-site versus two-site phacotrabecuiectomy in the treatment of patients with coexisting cataract and glaucoma.Methods A comprehensive literature search was performed according to the Cochrane Collaboration methodology toidentify randomized controlled clinical trials comparing one-site with two-site phacotrabeculectomy.Studies meeting our predefined criteria were included in the meta-analysis.Efficacy estimates were measured by weighted mean difference (WMD) for the percentage intraocular pressure (IOP) reduction from baseline to end point, relative risk (RR) for the proportion of patients with a best-corrected visual acuity (BCVA) of 0.5 or better after surgery and complete success rates.Tolerability estimates were measured by RR for adverse events.All of outcomes were reported with 95% confidence interval (95% CI).Data were synthesised by Stata 10.1 for Windows.Results Two-site phacotrabeculectomy was associated with greater reductions in IOP than the one-site procedure (WMD: -5.99, 95% CI: -10.74-1.24, P=0.01).A greater proportion of patients also achieved a BCVA of 0.5 or better (RR:0.91, 95% CI: 0.74-1.12, P=0.36) and the target IOP without anti-glaucoma medication at the study end point (RR: 0.94,95% CI: 0.83-1.07, P=0.34) after two-site than one-site phacotrabeculectomy, but the differences were not significant.There were no significant differences in adverse events between two surgical procedures.Conclusions Two-site phacotrabeculectomy is superior to one-site phacotrabeculectomy in reducing IOP, but other post-operative effects are similar.One-site and two-site phacotrabeculectomies have similar adverse event rates. 相似文献
