Purpose: To evaluate real-life outcomes of XEN45 stent surgery including bleb needling (BN) and surgical bleb revision (SBR). Methods: Retrospective analysis of all XEN45 gel stents implanted in a tertiary glaucoma center with a minimum follow-up of 6 months. The main outcomes were intraocular pressure (IOP), the number of glaucoma medications, postoperative maneuvers like BN, and subsequent SBR. Success was defined as IOP ⩽ 18 and 20% reduction (criterion A), ⩽15 and 25% reduction (criterion B), and ⩽12 mmHg and 30% reduction (criterion C) reached with (qualified) or without (complete) medications at the last visit. Complete failure was defined as additional glaucoma surgery, loss of light perception, or sight-threatening complications. Multivariable Cox regression and Kaplan-Meier survival estimates tests were performed. Results: Fifty-eight eyes with either stand-alone or combined Phaco-XEN surgery were included. Complete success by the different definitions was 50.0% (95% confidence interval, 5.8%–84.5%) (A), 50.0% (5.8%–84.5%) (B), and 25% (0.9%–66.5%) (C) whereas qualified success was 38.3% (1.6%–80.1%), 31.7% (2.0%–71.4%), and 0%, respectively, at the 24-months visit. 30% of cases underwent BN with 5-Fluorouracil, and SBR was performed in 17.5% of eyes. Low IOP levels at 1-month and early BN were significantly associated with success. The highest chance of failure was achieved in the combined Phaco-XEN group undergoing SBR. Conclusions: In our real-life setting, the first month IOP was associated with greater success rates. Although BN obtained improved IOP values, SBR was associated with a greater bleb survival in the stand-alone XEN group. Both BN and SBR had poor outcomes in the combined Phaco-XEN group.

Abstract Purpose To compare clinical success rates and reductions in intraocular pressure (IOP) and IOP-lowering medication use following suture trabeculotomy ab interno (S group) or microhook trabeculotomy (μ group). Methods This retrospective review collected data from S (n = 104, 122 eyes) and μ (n = 42, 47 eyes) groups who underwent treatment between June 1, 2016, and October 31, 2019, and had 12-month follow-up data including IOP, glaucoma medications, complications, and additional IOP-lowering procedures. The Kaplan–Meier survival analysis was used to evaluate treatment success rates defined as normal IOP (> 5 to ≤ 18 mm Hg), ≥ 20% reduction of IOP from baseline at two consecutive visits, and no further glaucoma surgery. Results Schlemm’s canal opening was longer in the S group than in the μ group (P < 0.0001). The Kaplan–Meier survival analysis of all eyes showed cumulative clinical success rates in S and µ groups were 71.1% and 61.7% (P = 0.230). The Kaplan–Meier survival analysis of eyes with preoperative IOP ≥ 21 mmHg showed cumulative clinical success rates in S and μ groups were 80.4% and 60.0% (P = 0.0192). There were no significant differences in postoperative IOP at 1, 3, and 6 months (S group, 14.9 ± 5.6, 14.6 ± 4.5, 14.6 ± 3.9 mmHg; μ group, 15.8 ± 5.9, 15.2 ± 4.4, 14.7 ± 3.7 mmHg; P = 0.364, 0.443, 0.823), but postoperative IOP was significantly lower in the S group at 12 months (S group, 14.1 ± 3.1 mmHg; μ group, 15.6 ± 4.1 mmHg; P = 0.0361). There were no significant differences in postoperative numbers of glaucoma medications at 1, 3, 6, and 12 months (S group, 1.8 ± 1.6, 1.8 ± 1.5, 2.0 ± 1.6, 1.8 ± 1.5; μ group, 2.0 ± 1.6, 2.0 ± 1.6, 2.1 ± 1.6, 2.2 ± 1.7; P = 0.699, 0.420, 0.737, 0.198). Conclusion S and µ group eyes achieved IOP reduction, but μ group eyes had lower clinical success rates among patients with high preoperative IOP at 12 months.

11548 Background: The mainstay therapy of operable STS remains surgery, which may include (neo)adjuvant therapies. Within the TSP, marginally inoperable STS are often treated with sequential chemo (CTX) and radiation (RT) therapy, followed by surgery (SX). Herein we present our experience of multi-modality therapies for marginally inoperable STS patients (pts). Methods: This was a dual-center, single program, retrospective review. Pts were included if deemed to have marginally inoperable primary or recurrent STS, as determined at the TSP tumor board. Pts included must have had CTX with the intent of having RT and SX after. Pts demographics, treatment details and clinical outcomes data were collected. Relapse free survival (RFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Multivariate analysis of the influence of disease characteristics and treatment on outcomes was assessed using Cox regression. Results: From June 2005 to May 2019, 75 pts were identified. Median age was 52 years (range 16-72). Pts were predominantly male (55%). Histological subtypes included dedifferentiated liposarcoma (29%), leiomyosarcoma (27%), synovial sarcoma (19%) and others (25%). Primary tumor was located in the retroperitoneum (48%), extremity (23%), pelvis (12%), thorax (9%), and other sites (8%). All pts had doxorubicin and ifosfamide CTX (median 4 cycles; range 1-6), while RT dose delivered was 50.4Gy/28 fractions in 58 (77%) of cases. Twenty three pts (31%) achieved partial response, 40 pts (53%) had stable disease and 12 pts (16%) had progression of disease (PD) on CTX, of which half (8%) did not undergo further treatment. Nine pts (12%) underwent CTX followed by SX due to significant response, 9 pts (12%) underwent CTX and RT without SX due to persistent tumor unresectability or PD. The final 50 pts (67%) completed multi-modality treatment (CTX, RT & SX). Overall, 59 pts (79%) had SX; negative margins were achieved in 53 (71%). 19 pts (25%) had postoperative complications, causing death in 2 pts (2.7%). With a median follow-up of 72 months, median RFS and OS were 26.9 months (95% CI: 0-86.0), and 65 months (95% CI: 13.5-116.4). Extremity location was associated with superior RFS (median not reached [NR], HR 0.28 95% CI 0.09-0.83, p = 0.022), and OS (median NR, HR 0.29 95% CI 0.09-0.90, p = 0.032). Receipt of RT was associated with superior RFS (median NR, HR 0.23 95% CI 0.10-0.52, p < 0.001); and OS (median NR, HR 0.21 95% CI 0.09-0.50, p < 0.001). Pts who had PD after CTX were associated with poor outcomes - RFS (median 4.7 months, HR 2.03 95% CI 0.61-6.76, p = 0.24); and OS (median 21.9 months, HR 2.48 95% CI 0.73-8.47, P = 0.144). Conclusions: Multi-modality approach resulted in successful resection for most pts with marginally inoperable STS. Extremity location and RT administration were associated with better RFS and OS, while progression on CTX confers worse survival outcomes.

Abstract Purpose To compare efficacy and safety of needling and open bleb revision after XEN-45 surgery. Methods This retrospective study represents real-life data of patients who underwent XEN-45 surgery between November 2014 and June 2018 in the Vienna General Hospital. The following groups were formed for data evaluation: (PSEA) primary surgery secondary intervention allowed (n = 268); (PS) primary surgery until secondary intervention (n = 268); (N) first needling until additional secondary intervention (n = 55); (BR) first bleb revision until additional secondary intervention (n = 105). Main outcome measures were pre- and postoperative intraocular pressure (IOP), number of glaucoma medication (GM), Kaplan–Meier success rates, and secondary intervention rates. Success was defined as postoperative IOP < 21 mmHg and < 18 mmHg together with ≥ 20% IOP reduction with medication allowed. Results IOP (and GM) was lowered from 23.5 ± 8.0 (GM 3.1 ± 1.0) to 14.9 ± 8.2 mmHg (1.2 ± 1.4) in group PSEA and 18.1 ± 8.2 mmHg (1.5 ± 1.4) in group PS, in group N from 23.2 ± 10.1 (1.5 ± 1.0) to 19.3 ± 8.5 mmHg (2.2 ± 1.3) and in group BR from 22.0 ± 8.0 mmHg (2.5 ± 1.1) to 15.5 ± 6.4 mmHg (1.3 ± 1.5) after a median follow-up of 16.0, 8.4, 4.8, and 7.3 months, respectively. Success rates at 1 year were significantly higher in group BR (50.7%) compared to PS (37.7%, p = 0.019) and N (24.3%; p = 0.015). An additional intervention was required less frequently in group BR (17.1%) compared to group PS (49.6%, p < 0.001) and group N (54.5%, p < 0.001). Conclusion Our data appear to indicate favorable outcomes for open XEN bleb revision in terms of Kaplan–Meier success rates and secondary intervention rate compared to the needling procedure.

Abstract Introduction: Identification of patients with high-risk (HR) multiple myeloma (MM) is important to optimise their treatment. In 2015, revised International Staging System (R-ISS) guidelines were published (Palumbo, 2015) where HR cytogenetics (CG) and elevated serum lactase dehydrogenase (LDH) were added to the traditional ISS staging criteria. Thus, R-ISS stage III includes one of the HR CG abnormalities or elevated LDH, ISS stage I patients have no HR CG and normal LDH; the rest of patients belong to R-ISS stage II. There are limited data on the prevalence of R-ISS groups in comparison to the old ISS grouping and impact on clinical outcomes in the real-life setting. The aim of the present analysis was to use structured longitudinal electronic health records (EHR) provided by the Finnish Auria Biobank to compare the prevalence and survival outcome between patients in ISS and R-ISS groups in a real-life patient cohort of 100 patients treated at Turku University Hospital. Auria Biobank covers roughly 15% of the population of Finland and collects samples with the associated data from all diseases treated at Turku University Hospital based on the Finnish Biobank Act. Methods: Auria Biobank database was analysed retrospectively for all MM-patients diagnosed between 2008-2013 (incident cohort) and whose fluorescence in situ hybridization analysis was performed at the time of diagnosis. Data for age, gender, LDH, creatinine, ISS, R-ISS, CG, time to next treatment and overall survival were collected from Auria Biobank. Classification into ISS groups was done based on data at the time of diagnosis and OS. Classification into R-ISS staging was done according to IMWG (Palumbo, 2015). For HR CG at least one of the following CG abnormalities was required: del(17), t(4:14), or t(14:16). Estimated glomerular filtration rate was calculated by using the CKD-EPI formula. Drug treatments were classified as conventional (e.g. melphalan + prednisolone) or novel (proteasome inhibitors, IMIDs). Descriptive methods and Kaplan-Meier survival analysis were used for comparison of the groups. Results: The median age of the 100 patients was 64 yrs (range: 37 - 80), and 43% were female. At the time of diagnosis, 17% of patients had high risk CG status, 32% had at least moderate kidney failure (estimated glomerular filtration rate <60ml/min) and 26 % had elevated LDH. 41% patients received autologous stem cell transplant and 64% and 14% were treated with novel and conventional treatments in first line, respectively. 26%, 48% and 26% were classified to ISS stage I, II and III groups respectively, and 21%, 63% and 16% to R-ISS stage I, II and III groups, respectively. Criteria to include patients into R-ISS III were HR CG in 62 %, elevated LDH in 69 % and 31 % fulfilled both criteria. Neither ISS- nor R-ISS staging had any influence on first line treatment decisions between novel and conventional treatments. In all patients 2-year OS (from diagnosis) was 82% (median OS not yet reached). The 2-year OS in ISS I, II and III groups was 90%, 88%, and 60% respectively, and in R-ISS I, II and III groups 87%, 85% and 42%, respectively. R-ISS had a statistically significant effect on survival time (log rank P=0.032), with R-ISS III patients having a 3.8-fold risk of death compared to R-ISS I (Fig 1). R-ISS III patients had also shorter (ns) treatment free survival than R-ISS I patients (HR 2.1, log rank P=0.479) (Fig 2). No statistically significant difference was observed between the survival curves stratified by ISS staging groups. Conclusion: The new R-ISS staging system, using additional information including CG-profile and serum LDH, separated in our real-life setting more profoundly patients with poor prognosis than the old ISS staging. Structured EHRs can successfully be used to derive useful clinical and prognostic data from real-life MM patients. Figure 1 Kaplan-Meier curves for overall survival in different R-ISS groups.

Abstract Background: New antiretrovirals improved the treatment success for heavily experienced HIV-infected patients as treatment failures or resistance to ART may limit the options for further therapy. Nonetheless, construction of ‘salvage’ regimens remains a complex and challenging issue worldwide. This study assessed real-life virologic success, long-term survival and adverse events in treatment experienced patients initiating either Raltegravir or other drugs for salvage regimens.Methods: we conducted a retrospective cohort study on adults with treatment failure (HIV-1 RNA viral load [PVL] >1000 copies/mL) who started either Raltegravir or other drugs (Darunavir/Ritonavir, Maraviroc or Etravirine). Propensity score (PS) matching methods were used to account for baseline clinical differences. We used Kaplan-Meier method and Generalized Wilcoxon tests for the matched subset to evaluate probability of virologic suppression (PVL<50 copies/mL) during follow up. Comparison of Mortality rates, cases of toxicity, treatment interruption, virologic failure and loss of follow-up, were ascertained using Poisson regression.Results: 168 patients (123 on Raltegravir; 45 on other drugs). Of these, 90 patients were matched by PS, 45 patients from each group, equivalent to 98 person-years of follow-up. During follow-up, virologic suppression was similar for both regimens (77.8% vs 82.2%, p=0.73). During a mean follow-up of 1.09 (SD = 0.32) years rates of mortality (4.04 vs 6.18 persons per 100 person-years; p=0.67), drug toxicity (0.00 vs 2.06 persons per 100 person-years; p=0.49), treatment interruption (8.07 vs 0.00 persons per 100 person-years; p=0.06), virologic failure (2.02 vs 4.12 persons per 100 person-years; p=0.61) and loss of follow-up (6.05 vs 4.12 persons per 100 person-years; p=0.70) did not differ between Raltegravir and other salvage regimens recipients.Conclusion: Similar survival and virologic success rates were found for Raltegravir and other drugs for salvage regimens, with similar rates of drug toxicity, treatment interruption, virologic failure and loss of follow-up.

Background/Aims. Previous studies have reported p-cresyl sulfate (PCS) was related to endothelial dysfunction and adverse clinical effect. We investigate the adverse effects of PCS on clinical outcomes in a chronic kidney disease (CKD) cohort study.Methods. 72 predialysis patients were enrolled from a single medical center. Serum biochemistry data and PCS were measured. The clinical outcomes including cardiovascular event, all-cause mortality, and dialysis event were recorded during a 3-year follow-up.Results. After adjusting other independent variables, multivariate Cox regression analysis showed age (HR: 1.12,P=0.01), cardiovascular disease history (HR: 6.28,P=0.02), and PCS (HR: 1.12,P=0.02) were independently associated with cardiovascular event; age (HR: 0.91,P<0.01), serum albumin (HR: 0.03,P<0.01), and PCS level (HR: 1.17,P<0.01) reached significant correlation with dialysis event. Kaplan-Meier analysis revealed that patients with higher serum p-cresyl sulfate (>6 mg/L) were significantly associated with cardiovascular and dialysis event (log rankP=0.03, log rankP<0.01, resp.).Conclusion. Our study shows serum PCS could be a valuable marker in predicting cardiovascular event and renal function progression in CKD patients without dialysis.

Background:LN is still a severe manifestation of Systemic lupus erythematosus (SLE) and multitarget therapy is needed to control the disease especially in refractory cases.Objectives:To evaluate renal response in SLE patients with glomerulonephritis (GN) treated with Belimumab in real-life setting.Methods:Patients with proteinuria >0.5 g/24 h and/or active sediment at baseline enrolled in a multicentre Italian cohort of SLE patients (BeRLiSS study), treated with monthly iv Belimumab 10 mg/kg plus standard of care were considered in this study. Complete renal response (CRR) was defined as proteinuria <0.5 g/24 h, estimated glomerular filtration rate (eGFR)≥90ml/min/1.73m2 and no rescue therapy. Primary efficacy renal response (PERR) was defined as proteinuria ≤0.7 g/24 h, eGFR ≥60ml/min/1.73m2 and no rescue therapy. Prevalence and predictive factors of CRR and PERR at 12 and 24 months after Belimumab initiation were analyzed by multivariate logistic regression analysis.Results:A total of 91 patients were considered in this study, 79 female, mean age 40.51±9.03 years, mean disease duration 12.18±8.15 years, median follow-up time after Belimumab initiation 22 months. Twenty patients had baseline proteinuria ≥0.5 <1 g/day, 17 ≥1 <2 g/day, 13 ≥2 g/day. Belimumab was started at GN onset in 20 (22%) patients and at the time of a renal flare in all other cases. Seventy-five patients underwent a renal biopsy: 1 class I, 4 class II, 14 class III, 47 class IV and 9 class V. Baseline serum creatinine was 82.44±29.26 umol/L; 15 patients showed eGFR<60ml/min/1.73m2 at baseline. Immunosuppresants were taken by 70 (76.9%) patients: 47 micofenolate, 15 azathioprine and 5 ciclosporine. Sixty patients (65.9%) were on antimalarials. During follow-up 34 (37.4%) patients achieved CRR. Among them 5 (14.7%) patients relapsed and 29 (85.3%) patients maintained remission. Mean time to achieved CRR was 9.71±5.91 months.High levels of baseline proteinuria were a negative independent predictor of CRR and PERR at 6 months (OR 0.044 CI95% 0.006-0.320 p=0.002 and OR 0.232 CI95% 0.091-0.596 p=0.002) and 12 months (OR 0.029 CI95% 0.002-0.556 p=0.019 and OR 0.056 CI95% 0.009-0.327 p=0.001). High levels of baseline creatinine were a negative independent predictor of renal response. Renal response at 6 months was a strong predictive factor of renal response at 12 and 24 months.Conclusion:Belimumab is an effective add-on therapy in the treatment of GN in real-life practice setting.Disclosure of Interests:None declared

BackgroundCoronary artery aneurysms (CAAs) are increasingly diagnosed on coronary angiography; however, controversies persist regarding their optimal management. In the present study, we analysed the long-term outcomes of patients with CAAs following three different management strategies.MethodsWe performed a retrospective review of patient records with documented CAA diagnosis between 2000 and 2005. Patients were divided into three groups: medical management versus percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG). We analysed the rate of major cardiovascular and cerebrovascular events (MACCEs) over a period of 10 years.ResultsWe identified 458 patients with CAAs (mean age 78±10.5 years, 74.5% men) who received medical therapy (N=230) or underwent PCI (N=52) or CABG (N=176). The incidence of CAAs was 0.7% of the total catheterisation reports. The left anterior descending was the most common coronary artery involved (38%). The median follow-up time was 62 months. The total number of MACCE during follow-up was 155 (33.8%); 91 (39.6%) in the medical management group vs 46 (26.1%) in the CABG group vs 18 (34.6%) in the PCI group (p=0.02). Kaplan-Meier survival analysis showed that CABG was associated with better MACCE-free survival (p log-rank=0.03) than medical management. These results were confirmed on univariate Cox regression, but not multivariate regression (OR 0.773 (0.526 to 1.136); p=0.19). Both Kaplan-Meier survival and regression analyses showed that dual antiplatelet therapy (DAPT) and anticoagulation were not associated with significant improvement in MACCE rates.ConclusionOur analysis showed similar long-term MACCE risks in patients with CAA undergoing medical, percutaneous and surgical management. Further, DAPT and anticoagulation were not associated with significant benefits in terms of MACCE rates. These results should be interpreted with caution considering the small size and potential for selection bias and should be confirmed in large, randomised trials.

The use of hydraulic silicate cements (HSCs) for vital pulp therapy has been found to release calcium and hydroxyl ions promoting pulp tissue healing and mineralized tissue formation. The present study investigated whether HSCs such as mineral trioxide aggregate (MTA) affect their biological and antimicrobial properties when used as long-term pulp protection materials. The effect of variables on treatment outcomes of three HSCs (ProRoot MTA, OrthoMTA, and RetroMTA) was evaluated clinically and radiographically over a 48–78 month follow-up period. Survival analysis was performed using Kaplan–Meier survival curves. Fisher’s exact test and Cox regression analysis were used to determine hazard ratios of clinical variables. The overall success rate of MTA partial pulpotomy was 89.3%; Cumulative success rates of the three HSCs were not statistically different when analyzed by Cox proportional hazard regression analysis. None of the investigated clinical variables affected success rates significantly. These HSCs showed favorable biocompatibility and antimicrobial properties in partial pulpotomy of permanent teeth in long-term follow-up, with no statistical differences between clinical factors.

Background: There is a need for identifying risk factors for hospitalization in Parkinson’s disease (PD) and also interventions to reduce acute hospital admission. Objective: To analyze the frequency, causes, and predictors of acute hospitalization (AH) in PD patients from a Spanish cohort. Methods: PD patients recruited from 35 centers of Spain from the COPPADIS-2015 (COhort of Patients with PArkinson’s DIsease in Spain, 2015) cohort from January 2016 to November 2017, were included in the study. In order to identify predictors of AH, Kaplan-Meier estimates of factors considered as potential predictors were obtained and Cox regression performed on time to hospital encounter 1-year after the baseline visit. Results: Thirty-five out of 605 (5.8%) PD patients (62.5±8.9 years old; 59.8% males) presented an AH during the 1-year follow-up after the baseline visit. Traumatic falls represented the most frequent cause of admission, being 23.7% of all acute hospitalizations. To suffer from motor fluctuations (HR [hazard ratio] 2.461; 95% CI, 1.065–5.678; p = 0.035), a very severe non-motor symptoms burden (HR [hazard ratio] 2.828; 95% CI, 1.319–6.063; p = 0.008), falls (HR 3.966; 95% CI 1.757–8.470; p = 0.001), and dysphagia (HR 2.356; 95% CI 1.124–4.941; p = 0.023) was associated with AH after adjustment to age, gender, disease duration, levodopa equivalent daily dose, total number of non-antiparkinsonian drugs, and UPDRS-IIIOFF. Of the previous variables, only falls (HR 2.998; 95% CI 1.080–8.322; p = 0.035) was an independent predictor of AH. Conclusion: Falls is an independent predictor of AH in PD patients.
