Efficacy and safety of XEN®-Implantation vs. trabeculectomy: Data of a "real-world" setting.

ABSTRACT:

Objective

To compare surgical success, postoperative intraocular pressure and complication rates between trabeculectomy and XEN gelstent surgery in a cohort of glaucoma patients in a typical clinical setting.

Methods

A retrospective cohort study of consecutive patients with refractory open-angle glaucoma including patients who underwent either stand-alone XEN gelstent insertion with Mitomycin C or trabeculectomy with Mitomycin C between 2016 and 2018 at the University Eye Hospital Mainz, Germany. Primary outcome measure was the proportion of surgical success 1 year after surgery. Patients with an IOP ?18mmHg, an intraocular pressure reduction of >20% and in no need of revision surgery or topical medication were considered a complete surgical success. If topical therapy was necessary, they were considered a qualified success. Multivariable logistic regression analysis was carried out for the primary outcome including gender, age, preoperative intraocular pressure and number of medication classes used preoperatively as adjustment variables.

Results

171 eyes of 144 patients were included, including 82 eyes of 58 patients in the XEN group and 89 eyes of 86 patients in the trabeculectomy group. The primary outcome defined as the proportion of surgical success after 1 year (mean 11.1 months ± 2.2) was similar for both groups. The complete success proportion was 65.5% (95%-CI: 55.6-75.9%) in the trabeculectomy group, and 58.5% (95%-CI: 47.6-69.4%) in the XEN group and not statistically different in our analysis model (crude OR = 0.61; 95%-CI: 0.31-1.22; adjusted OR = 0.66; 95%-CI: 0.32-1.37). The intraocular pressure reduction, as secondary outcome measure, was higher in the trabeculectomy group (10.5 mmHg) compared to the XEN group (7.2 mmHg; p = 0.003) at the 12-month follow-up.

Conclusion

Both XEN gelstent implantation and trabeculectomy show similar proportions of surgical success and of complications and are therefore both recommendable for clinical routine. However, trabeculectomy seems to be more effective in lowering intraocular pressure than the XEN implantation. A prospective randomized clinical trial is necessary to evaluate differences in the long-term clinical outcome.

Project description:BackgroundThere are 3 main epileptic conditions in hospital settings that may require intravenous antiepileptic treatment: status epilepticus, acute repetitive convulsive seizures, and postoperative seizures. Generic intravenous levetiracetam (IV LEV) (Focale; Great Eastern Drug Co, Bangkok, Thailand), has been reported to have comparable efficacy to original IV LEV for treating status epilepticus and acute repetitive convulsive seizures in a randomized controlled trial. At present, there are limited data on the efficacy and tolerability of generic intravenous LEV in real-world situations.ObjectiveThis study aimed to evaluate the clinical outcomes of generic IV LEV in a real-world setting.MethodsA retrospective study and analyses were conducted. All adult patients who used IV LEV at University Hospital, Khon Kaen University, Thailand from June 1, 2019, until February 15, 2020, were included. Data were analyzed and reported in terms of the efficacy and tolerability of generic IV LEV.ResultsNinety-three patients received IV LEV by 3 indications: status epilepticus, acute repetitive convulsive seizures, and postoperative seizures. The proportions of these 3 indications were 41.94% (39 patients), 9.67% (9 patients), and 48.39% (45 patients), respectively. The average seizure control rate at 24 hours was 89.25%. The seizure control rate was significantly higher in the acute repetitive convulsive seizures and postoperative seizure groups than in the status epilepticus group when generic IV LEV was given as the first-line treatment (75.00%; 88.37% vs 50.00%; P 0.035). The average length of hospital stay was 18.24 (25.40) days. There was no significant discharge status among the 3 groups (P = 0.348). Moreover, the average mortality rate was 5.38%. Side effects were reported in 14 patients (15.05%). The 2 most common side effects were vomiting and bronchospasm (3 patients; 3.22%). There were 10 patients with uncontrolled seizures at 24 hours (10.75%). The only factor associated with uncontrolled seizures at 24 hours was a history of epilepsy. The uncontrolled seizure group had a higher proportion of epilepsy patients than the seizure-controlled group (70.00% vs 33.73%; P = 0.037). Poor discharge status (not improved/death) was 18.28% (17 patients). There was no significant factor between those with an improved or poor discharge status.ConclusionsGeneric IV LEV was effective and relatively well tolerated in the 3 clinical settings (ie, status epilepticus, acute repetitive convulsive seizures, and postoperative seizures). Further clinical data are still required to confirm the results of this study.(Curr Ther Res Clin Exp. 2022; 83:XXX-XXX).

Project description:BackgroundIn patients with advanced hepatocellular carcinoma (HCC) progressing after atezolizumab and bevacizumab, the optimal therapeutic sequence is still unclear and no second-line agent has proven its efficacy.ObjectivesThe aim of this retrospective multicenter real-world cohort study was to provide an evaluation of the efficacy and safety of the use of second-line tyrosine kinase inhibitors (TKIs) in this population.MethodsAll patients with advanced HCC, treated in first-line setting by atezolizumab-bevacizumab, and who received at least one dose of treatment with TKI were included in this study. All the data were retrospectively collected from medical records. The primary outcome was progression-free survival (PFS). Secondary outcomes were overall survival (OS), overall global survival (OGS), and safety. A total of 82 patients were included in this study.ResultsPatients were assigned to the regorafenib group (n = 29, 35.4%) or other TKI (sorafenib n = 41, lenvatinib n = 8, or cabozantinib n = 4) group (n = 53). PFS was not significantly different between the two groups [2.6 versus 2.8 months, HR 1.07 (95% CI: 0.61-1.86), p = 0.818]. Median PFS rates were 2.6, 4.4, and 2.8 months in sorafenib-, lenvatinib-, and cabozantinib group, respectively. OS was statistically different between the regorafenib group and other TKI group [15.8 versus 7.0 months, HR 0.40 (95% CI: 0.20-0.79), p = 0.023]. When adjusting on confounding factors, there was still a difference in OS favoring the regorafenib group (adjusted hazard ratio 0.35, p = 0.019). OGS of patients who received regorafenib was improved compared to other TKI [18.6 versus 15.0 months, HR 0.42 (95% CI: 0.22-0.84), p = 0.036]. Twenty percent of patients had grade 3 and none had grade 4 or 5 adverse events. In patients who experienced disease progression and fit for a third-line treatment, 80% and 50% received cabozantinib in regorafenib group and other TKI group, respectively.ConclusionEfficacy of any TKI in the second-line setting was not affected by atezolizumab-bevacizumab treatment as first-line therapy. The safety profile in the second-line setting was consistent with the results shown in pivotal studies. PFS rates of patients were similar, regardless of TKI type. Regorafenib was associated with better OS and OGS rates compared to other TKI. These data need to be confirmed in prospective comparative studies.
