Effects of nintedanib on symptoms in patients with progressive pulmonary fibrosis.

BACKGROUND: Dyspnoea and cough can have a profound impact on the lives of patients with pulmonary fibrosis. We investigated the effects of nintedanib on the symptoms and impact of pulmonary fibrosis in patients with progressive pulmonary fibrosis (PPF) in the INBUILD trial using the Living with Pulmonary Fibrosis (L-PF) questionnaire. METHODS: Patients had a fibrosing interstitial lung disease (ILD) (other than idiopathic pulmonary fibrosis) of >10% extent on high-resolution computed tomography (HRCT) and met criteria for ILD progression within the prior 24 months. Patients were randomised 1:1 to receive nintedanib or placebo. Changes in L-PF questionnaire scores from baseline to week 52 were assessed using mixed models for repeated measures. RESULTS: In total, 663 patients were treated. Compared with placebo, there were significantly smaller increases (worsenings) in adjusted mean L-PF questionnaire total (0.5 versus 5.1), symptoms (1.3 versus 5.3), dyspnoea (4.3 versus 7.8) and fatigue (0.7 versus 4.0) scores in the nintedanib group at week 52. L-PF questionnaire cough score decreased in the nintedanib group and increased in the placebo group (-1.8 versus 4.3). L-PF questionnaire impacts score decreased slightly in the nintedanib group and increased in the placebo group (-0.2 versus 4.6). Similar findings were observed in patients with a usual interstitial pneumonia-like fibrotic pattern on HRCT and in patients with other fibrotic patterns on HRCT. CONCLUSION: Based on changes in L-PF questionnaire scores, nintedanib reduced worsening of dyspnoea, fatigue and cough and the impacts of ILD over 52 weeks in patients with PPF.

Effect of Nintedanib in Patients with Progressive Pulmonary Fibrosis in Subgroups with Differing Baseline Characteristics.

INTRODUCTION: In the INBUILD trial in patients with progressive pulmonary fibrosis other than idiopathic pulmonary fibrosis (IPF), nintedanib slowed the rate of decline in forced vital capacity (FVC; mL/year) over 52 weeks compared with placebo. We assessed the efficacy of nintedanib across subgroups in the INBUILD trial by baseline characteristics. METHODS: We assessed the rate of decline in FVC over 52 weeks and time to progression of interstitial lung disease (ILD) (absolute decline from baseline in FVC % predicted > 10%) or death over the whole trial in subgroups based on sex, age, race, body mass index (BMI), time since diagnosis of ILD, FVC % predicted, diffusing capacity of the lungs for carbon monoxide (DLco) % predicted, composite physiologic index (CPI), GAP (gender, age, lung physiology) stage, use of anti-acid therapy and use of disease-modifying antirheumatic drugs (DMARDs) at baseline. RESULTS: The effect of nintedanib versus placebo on reducing the rate of decline in FVC over 52 weeks was consistent across the subgroups by baseline characteristics analysed. Interaction p values did not indicate heterogeneity in the treatment effect between these subgroups (p > 0.05). Over the whole trial (median follow-up time ∼19 months), progression of ILD or death occurred in similar or lower proportions of patients treated with nintedanib than placebo across the subgroups analysed, with no heterogeneity detected between the subgroups. CONCLUSIONS: In the INBUILD trial, no heterogeneity was detected in the effect of nintedanib on reducing the rate of ILD progression across subgroups based on demographics, ILD severity or use of anti-acid therapy or DMARDs. These data support the use of nintedanib as a treatment for progressive pulmonary fibrosis. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier: NCT02999178.

Effect of nintedanib in patients with progressive pulmonary fibrosis associated with rheumatoid arthritis: data from the INBUILD trial.

OBJECTIVES: Some patients with rheumatoid arthritis develop interstitial lung disease (RA-ILD) that develops into progressive pulmonary fibrosis. We assessed the efficacy and safety of nintedanib versus placebo in patients with progressive RA-ILD in the INBUILD trial. METHODS: The INBUILD trial enrolled patients with fibrosing ILD (reticular abnormality with traction bronchiectasis, with or without honeycombing) on high-resolution computed tomography of >10% extent. Patients had shown progression of pulmonary fibrosis within the prior 24 months, despite management in clinical practice. Subjects were randomised to receive nintedanib or placebo. RESULTS: In the subgroup of 89 patients with RA-ILD, the rate of decline in FVC over 52 weeks was -82.6 mL/year in the nintedanib group versus -199.3 mL/year in the placebo group (difference 116.7 mL/year [95% CI 7.4, 226.1]; nominal p = 0.037). The most frequent adverse event was diarrhoea, which was reported in 61.9% and 27.7% of patients in the nintedanib and placebo groups, respectively, over the whole trial (median exposure: 17.4 months). Adverse events led to permanent discontinuation of trial drug in 23.8% and 17.0% of subjects in the nintedanib and placebo groups, respectively. CONCLUSIONS: In the INBUILD trial, nintedanib slowed the decline in FVC in patients with progressive fibrosing RA-ILD, with adverse events that were largely manageable. The efficacy and safety of nintedanib in these patients were consistent with the overall trial population. A graphical abstract is available at: https://www.globalmedcomms.com/respiratory/INBUILD_RA-ILD . Key Points • In patients with rheumatoid arthritis and progressive pulmonary fibrosis, nintedanib reduced the rate of decline in forced vital capacity (mL/year) over 52 weeks by 59% compared with placebo. • The adverse event profile of nintedanib was consistent with that previously observed in patients with pulmonary fibrosis, characterised mainly by diarrhoea. • The effect of nintedanib on slowing decline in forced vital capacity, and its safety profile, appeared to be consistent between patients who were taking DMARDs and/or glucocorticoids at baseline and the overall population of patients with rheumatoid arthritis and progressive pulmonary fibrosis.

Responsiveness and meaningful change thresholds of the Living with Pulmonary Fibrosis (L-PF) questionnaire Dyspnoea and Cough scores in patients with progressive fibrosing interstitial lung diseases.

BACKGROUND: The Living with Pulmonary Fibrosis (L-PF) questionnaire assesses symptoms and quality of life in patients with fibrosing interstitial lung diseases (ILDs). Its Dyspnoea and Cough domains, whose items' responses are based on a 24-hour recall, have scores ranging from 0 to 100, with higher scores indicating greater symptom severity. We evaluated the ability of these domain scores to detect change and estimated their meaningful change thresholds in patients with progressive fibrosing ILDs. METHODS: The INBUILD trial enrolled subjects with progressive fibrosing ILDs other than idiopathic pulmonary fibrosis. The L-PF questionnaire was completed at baseline and week 52. The responsiveness of the Dyspnoea and Cough scores was evaluated by comparing changes in these scores with 52-week changes in three anchors: forced vital capacity % predicted and two self-reported items, one for global physical health and one for global quality of life. We used a triangulation approach including anchor-based and distribution-based methods to estimate meaningful change thresholds. RESULTS: The analyses included 542 subjects with an L-PF Dyspnoea score at baseline and week 52, and 538 subjects with an L-PF Cough score at baseline and week 52. The L-PF Dyspnoea and Cough scores were responsive to change over 52 weeks. Triangulation of anchor-based and distribution-based estimates resulted in meaningful change thresholds of 6 to 7 points for the L-PF Dyspnoea score and 4 to 5 points for the L-PF Cough score to differentiate subjects who were stable or improved from those who deteriorated. CONCLUSION: These analyses support the responsiveness, one aspect of validity, of the L-PF Dyspnoea and Cough domains scores as measures of symptom severity in patients with progressive fibrosing ILDs. Estimates for meaningful change thresholds in these domain scores may be of value in interpreting the effects of interventions in these patients. TRIAL REGISTRATION NUMBER: NCT02999178.

The psychometric properties of the King's Brief Interstitial Lung Disease questionnaire and thresholds for meaningful treatment response in patients with progressive fibrosing interstitial lung diseases.

BACKGROUND: There is a lack of fully validated patient-reported outcome measures for progressive fibrosing interstitial lung disease (ILD). We aimed to validate the King's Brief Interstitial Lung Disease (K-BILD) questionnaire for measuring health-related quality of life (HRQoL) in these patients. We also aimed to estimate the meaningful change threshold for interpreting stabilisation of HRQoL as a clinical end-point in progressive fibrosing ILD, where the current goal of treatment is disease stability and slowing progression. METHODS: This analysis evaluated data from 663 patients with progressive fibrosing ILD other than idiopathic pulmonary fibrosis from the INBUILD trial. Validation of the measurement properties was assessed for internal consistency, test-retest reliability, construct validity, known-groups validity and responsiveness. We calculated meaningful change thresholds for treatment response using anchor-based (within-patient) and distribution-based methods. RESULTS: K-BILD had strong internal consistency (Cronbach's α was 0.94 for total score, 0.88 for breathlessness and activities, 0.91 for psychological, and 0.79 for chest symptoms). The test-retest reliability intraclass correlation coefficient was 0.74 for K-BILD total score. K-BILD demonstrated weak correlations with forced vital capacity (FVC) percent predicted. Known-groups validity showed significant differences in K-BILD scores for patient groups with different disease severity based on use of supplemental oxygen or baseline FVC % pred (≤70% or >70%). We estimated a meaningful change threshold of ≥ -2 units for K-BILD total score for defining patients who remain stable/improved versus those with progressive deterioration. CONCLUSIONS: Our results validate K-BILD as a tool for assessing HRQoL in patients with progressive fibrosing ILD and set a meaningful change threshold of ≥ -2 units for K-BILD total score.

Treatment with EPs 7630, a Pelargonium Sidoides Root Extract, Is Effective and Safe in Patients with the Common Cold: Results From a Randomized, Double Blind, Placebo-Controlled Clinical Trial.

BACKGROUND: EPs 7630 was shown to be effective and safe in the treatment of acute respiratory tract infections such as acute bronchitis, acute rhinosinusitis, and acute tonsillopharyngitis. A clinical trial was conducted to investigate its efficacy and safety in the common cold. METHODS: In this multicenter, randomized, double-blind phase 3 clinical trial, 105 adults suffering from common cold symptoms were randomized to a thrice-daily administration of either 1 film-coated tablet containing 40 mg EPs 7630 or matched placebo for a treatment period of 10 days. The primary outcome measure was the sum of differences in the cold intensity score (CIS) from day 1 to day 5, defined as the Sum of the Symptom Intensity Differences (SSID), indicating the degree of symptom improvement in the course of 5 days of treatment. Among the secondary outcomes were clinical cure defined as (a) complete resolution of all cold symptoms (CIS = 0 points) or (b) complete resolution of all or all but one cold symptom, treatment outcome, satisfaction with treatment, and safety parameters. RESULTS: On day 5, the mean (±SD) SSID was significantly higher in the EPs 7630 group compared with the placebo group (12.5 ± 4.4 points versus 8.8 ± 6.8 points). Moreover, 55% of patients in the EPs 7630 group rated the treatment outcome as at least "major improvement" compared with 15% of patients in the placebo group. On day 10, 45% of patients of the EPs 7630 group and 12% of patients of the placebo group had reached 0 points on the CIS (=clinical cure, definition a), whereas all or all but one symptom (clinical cure, definition b) had completely resolved in 74% (EPs 7630) and 25% of patients (placebo), respectively. Satisfaction with treatment was higher in the EPs 7630 than in the placebo group (75% vs 37%) (P values ≤ .0002). During the clinical trial, adverse events occurred in 5 patients (9.4%) in the EPs 7630 and in 7 (13.5%) in the placebo group. All adverse events were of mild intensity, with the exception of 3 events in the placebo group, which were classified as moderate. CONCLUSIONS: Treatment with EPs 7630 was shown to be superior to placebo in patients with the common cold indicating faster reduction of symptom intensity and distinctly more pronounced effects achieved by administration of the investigational drug in patients suffering from the common cold. Results extend previous findings on efficacy, safety, and tolerability of this active substance.

Ginkgo biloba extract EGb 761® alleviates neurosensory symptoms in patients with dementia: a meta-analysis of treatment effects on tinnitus and dizziness in randomized, placebo-controlled trials.

BACKGROUND: Tinnitus and dizziness are frequent in old age and often seen as concomitant symptoms in patients with dementia. In earlier clinical trials, Ginkgo biloba extract EGb 761® was found to alleviate tinnitus and dizziness in elderly patients. Consequently, a meta-analysis was conducted to evaluate the effects of EGb 761® at a daily dose of 240 mg on tinnitus and dizziness associated with dementia. METHODS: Randomized, placebo-controlled clinical trials of G. biloba extract EGb 761® identified by a systematic database search were included in a meta-analysis if they met all of the following selection criteria: 1) diagnosis of dementia according to generally accepted criteria, 2) treatment period of at least 20 weeks, 3) outcome measures covering at least two of the three conventional domains of assessment, 4) presence and severity of dizziness and tinnitus were assessed, and 5) assessment was done before and after randomized treatment. RESULTS: Five trials that met the inclusion criteria were included in the meta-analysis. The risk of bias was judged as low, with Jadad scores of 3 and 5. In all trials, 11-point box scales were used to assess the severity of tinnitus and dizziness. Overall, EGb 761® was superior to placebo, with weighted mean differences for change from baseline, calculated in meta-analyses using random effects models, of -1.06 (95% CI: -1.77, -0.36) for tinnitus (p = 0.003) and -0.77 (95% CI: -1.44, -0.09) for dizziness (p = 0.03). CONCLUSION: Our findings support the notion that EGb 761® is also effective in alleviating concomitant neurosensory symptoms in patients with dementia.

Treatment effects of Ginkgo biloba extract EGb 761® on the spectrum of behavioral and psychological symptoms of dementia: meta-analysis of randomized controlled trials.

ABSTRACTBackground:In randomized controlled trials, Ginkgo biloba extract EGb 761® has been found to be effective in the treatment of behavioral and psychological symptoms of dementia (BPSD). METHODS: To assess the effects of EGb 761® on specific BPSD, we analyzed data from all randomized, placebo-controlled, at least 20-week, trials of EGb 761® enrolling patients with dementia (probable Alzheimer's disease (AD), probable vascular dementia or probable AD with cerebrovascular disease) who had clinically significant BPSD (Neuropsychiatric Inventory (NPI) total score at least 6). Data were pooled and joint analyses of NPI single item composite and caregiver distress scores were performed by meta-analysis with a fixed effects model. RESULTS: Four trials involving 1628 patients (EGb 761®, 814; placebo, 814) were identified; treatment duration was 22 or 24 weeks; the daily dose of EGb 761® was 240 mg in all trials. Pooled analyses including data from the full analysis sets of all trials (EGb 761®, 796 patients; placebo, 802 patients) revealed significant superiority of EGb 761® over placebo in total scores and 10 single symptom scores. Regarding caregiver distress scores, EGb 761®-treated patients improved significantly more than those receiving placebo in all symptoms except delusions, hallucinations, and elation/euphoria. The benefit of EGb 761® mainly consists of improvement in symptoms present at baseline, but the incidence of some symptoms was also decreased. CONCLUSIONS: Twenty two- to twenty four-week treatment with Ginkgo biloba extract EGb 761® improved BPSD (except psychotic-like features) and caregiver distress caused by such symptoms.

Insulin Infusion Set Use: European Perspectives and Recommendations.

Insulin pump users worldwide depend on insulin infusion sets (IISs) for predictable delivery of insulin to the subcutaneous tissue. Yet emerging data indicates that IISs are associated with many pump-related adverse events and may contribute to potentially life-threatening problem of unexplained hyperglycemia. The relative scarcity of published research on IISs to date, the heterogeneity of regional IIS practices, and the increasing demand for international standards guiding their use prompted convening of a panel of diabetologists and diabetes nurse educators last February, in Milan, Italy, to discuss a framework for optimizing IIS practice in Europe. The multinational panel was tasked, first, with identifying the often-overlooked IIS issues that can affect patients' experience of pump therapy-e.g., partial or complete blockage of the cannula, skin pathologies, unpredictable variations in insulin absorption, dislodgment, and the demands of site rotation and set changes-and, second, with establishing direction for developing cohesive protocols to assure long-term success. As reported in this article, the panel examined IIS-related complications of pump therapy encountered in clinical practice, considered country-wide policies to prevent and mitigate such complications, and updated priorities for improving IIS education on issues of device selection, skin care, and troubleshooting unexplained hyperglycemia. These recommendations may be more relevant with the possibility of closed-loop systems available in the near future.

Increased risk of lung cancer in individuals with a family history of the disease: a pooled analysis from the International Lung Cancer Consortium.

BACKGROUND AND METHODS: Familial aggregation of lung cancer exists after accounting for cigarette smoking. However, the extent to which family history affects risk by smoking status, histology, relative type and ethnicity is not well described. This pooled analysis included 24 case-control studies in the International Lung Cancer Consortium. Each study collected age of onset/interview, gender, race/ethnicity, cigarette smoking, histology and first-degree family history of lung cancer. Data from 24,380 lung cancer cases and 23,305 healthy controls were analysed. Unconditional logistic regression models and generalised estimating equations were used to estimate odds ratios and 95% confidence intervals. RESULTS: Individuals with a first-degree relative with lung cancer had a 1.51-fold increase in the risk of lung cancer, after adjustment for smoking and other potential confounders (95% CI: 1.39, 1.63). The association was strongest for those with a family history in a sibling, after adjustment (odds ratios (OR) = 1.82, 95% CI: 1.62, 2.05). No modifying effect by histologic type was found. Never smokers showed a lower association with positive familial history of lung cancer (OR = 1.25, 95% CI: 1.03, 1.52), slightly stronger for those with an affected sibling (OR = 1.44, 95% CI: 1.07, 1.93), after adjustment. CONCLUSIONS: The occurrence of lung cancer among never smokers and similar magnitudes of the effect of family history on lung cancer risk across histological types suggests familial aggregation of lung cancer is independent of those risks associated with cigarette smoking. While the role of genetic variation in the aetiology of lung cancer remains to be fully characterised, family history assessment is immediately available and those with a positive history represent a higher risk group.

Quantitation of locked nucleic acid antisense oligonucleotides in mouse tissue using a liquid-liquid extraction LC-MS/MS analytical approach.

BACKGROUND: A significant challenge of oligonucleotide bioanalysis is the selective extraction from complex tissue samples, where the molecules that distribute into the intracellular space are extensively protein bound and sit amongst a high concentration of endogenous nucleic acid material. Published analytical methodology currently purports extensive sample preparation requirements that include cell lysis steps, homogenization and dual cleanup with liquid-liquid extraction and solid-phase extraction, prior to injection. RESULTS: We have developed a simple liquid-liquid extraction approach to rapidly isolate antisense oligonucleotides from biological tissues with high recovery and combined these preparative steps with a robust monolithic column LC-MS/MS setup. The platform showed improved chromatographic resolution and detection sensitivity over standard reversed-phase columns and required a low sample volume. CONCLUSION: The high-throughput method was sufficient to accurately quantify multiple antisense oligonucleotides in mouse tissue and plasma down to low ng/g and ng/ml levels, respectively, for pharmacokinetic determination, and exhibited a high degree of specificity.

The pattern of invasion of early carcinomas in Barrett's esophagus is dependent on the depth of infiltration.

The differential diagnosis "high-grade intraepithelial neoplasia" or "well-differentiated Barrett's adenocarcinoma limited to the mucosa" is controversial. We investigated 277 endoscopically resected specimens of early Barrett's carcinoma. Depth of infiltration was classified as follows: m 1=carcinoma limited to Barrett's mucosa; m 2=carcinoma infiltrating the neo-muscularis mucosae; m 3=infiltration of the original lamina propria of the esophageal mucosa; m 4=infiltration of the original muscularis mucosae; sm 1, sm 2, and sm 3=infiltration into the upper third, middle third, and lower third of the submucosa. The pattern of invasion was classified and graded as follows: tubular (D 0)=only neoplastic tubuli showing cytologic criteria of malignancy - no tumor cell dissociation; dissociation grade 1 (D 1)=few dissociated tumor cells; D 2=moderate amount of dissociated tumor cells; D 3=pronounced tumor cell dissociation. 74-96% of m 1-m 4 Barrett's carcinomas limited to the mucosa have a D 0-pattern. Tubular invasion decreases only when the submucosa has been infiltrated (sm 1: 70.4%, sm 2: 30.0%, sm 3: 24.0%). Our study shows that the pattern of invasion in early cancer in Barrett's esophagus statistically significantly depends on depth of infiltration.

Nature or nurture; BMI and blood pressure at 90. Findings from the Belfast Elderly Longitudinal Free-living Aging STudy (BELFAST).

Hypertension is a key risk factor for stroke, cardiovascular disease and dementia. Although the link between weight, sodium and hypertension is established in younger people, little is known about their inter-relationship in people beyond 80 years of age. Associations between blood pressure, anthropometric indices and sodium were investigated in 495 apparently healthy, community-living participants (age 90, SD 4.8; range 80­106), from the cross-sectional Belfast Elderly Longitudinal Free-living Aging STudy (BELFAST) study. In age-sex-adjusted logistic regression models, blood pressure ≥140/90 mmHg significantly associated with body mass index (BMI) [odds ratio (OR) = 1.28/ kg/m2], with weight (OR = 1.22/kg) approaching significance (P = 0.07). In further age-sex-adjusted models, blood pressure above the 120/80 mmHg normotensive reference value significantly associated with BMI (OR = 1.44/kg/m2), weight (OR = 1.36/kg), skin-fold-thickness (OR = 1.33/mm) and serum sodium (OR = 1.37 mmol/l). In BELFAST participants over 80 years old, blood pressure ≥140/90 mmHg is associated with BMI, in apparently similar ways to younger groups.

Bacterial base excision repair enzyme Fpg recognizes bulky N7-substituted-FapydG lesion via unproductive binding mode.

Fpg is a bacterial base excision repair enzyme that removes oxidized purines from DNA. This work shows that Fpg and its eukaryote homolog Ogg1 recognize with high affinity FapydG and bulky N7-benzyl-FapydG (Bz-FapydG). The comparative crystal structure analysis of stable complexes between Fpg and carbocyclic cFapydG or Bz-cFapydG nucleoside-containing DNA provides the molecular basis of the ability of Fpg to bind both lesions with the same affinity and to differently process them. To accommodate the steric hindrance of the benzyl group, Fpg selects the adequate rotamer of the extrahelical Bz-cFapydG formamido group, forcing the bulky group to go outside the binding pocket. Contrary to the binding mode of cFapydG, the particular recognition of Bz-cFapydG leads the BER enzymes to unproductive complexes which would hide the lesion and slow down its repair by the NER machinery.

Synthesis of a stabilized version of the imidazolone DNA lesion.

Imidazolone (dIz) is an abundant, highly mutagenic, and rather unstable DNA lesion that can cause dG-->dC transversion mutations. dIz is generated in DNA by a variety of oxidative processes such as type I photooxidation. Herein we report the synthesis of a carbocyclic nucleoside analogue of dIz and of DNA containing this stabilized lesion analogue. The carbocyclic modification protects this lesion analogue from anomerization. As the repair of the lesion analogue by DNA glycosylases is not possible, this analogue should allow cocrystallization studies together with wild-type repair enzymes. Characterization of the lesion analogue was performed by using spectroscopic methods and enzymatic digestion experiments of the oligonucleotides.

Combined endoscopic erbium:YAG laser goniopuncture and cataract surgery.

PURPOSE: To study the safety and efficacy of endoscopic erbium:YAG (Er:YAG) laser goniopuncture combined with cataract surgery to treat glaucoma. SETTING: Department of Ophthalmology, Albert-Ludwigs-University Freiburg, Freiburg, Germany, and Institute of Applied Physics, University of Bern, Bern, Switzerland. METHODS: In this nonrandominized clinical trial, 20 eyes of 20 patients with cataract and glaucoma were treated by combined phacoemulsification and Er:YAG goniopuncture. The primary study endpoints were intraocular pressure (IOP), visual acuity, and number of antiglaucoma drugs 1 year after surgery. Two- and 3-year postoperative data were also measured. This prospective treatment arm was compared to a retrospective inclusion-matched control group treated by cataract surgery alone. RESULTS: The mean IOP dropped by 30% (23.5 mm Hg +/- 3.9 [SD] to 16.3 +/- 2.7 mm Hg) after 12 months in the laser-treated group (P<.0001) and by 9% (19.8 +/- 1.3 mm Hg to 18.1 +/- 1.8 mm Hg) in the control group (P =.12). After 3 years, the mean IOP in the laser group was 15.0 +/- 2.0 mm Hg. The mean number of antiglaucoma drugs needed decreased from 1.6 +/- 0.9 to 0.5 +/- 0.8 in the laser group (P<.0001) and from 1.0 +/- 0.9 to 0.8 +/- 0.9 in the control group (P =.21). Anterior chamber hemorrhage occurred in 12 eyes after laser treatment and resolved within 72 hours in all but 1 patient who was on warfarin sodium (Coumadin) therapy. There were no cases of hypotony in either group. CONCLUSIONS: Endoscopic Er:YAG laser goniopuncture was a successful adjunct to cataract surgery in glaucoma patients. Sustained IOP reduction was achieved with few postoperative complications.

Comparison of long-term fluctuations: laser scanning tomography versus automated perimetry.

BACKGROUND: The aim of our study was to investigate the long-term variability of laser scanning tomography and to compare it with the long-term variability of automated perimetry. METHOD: We retrospectively reviewed the charts of 199 patients (394 eyes) who underwent both automated perimetry (Octopus) and laser scanning tomography (Heidelberg retina tomograph, HRT) in our hospital since 1994. All patients either had ocular hypertension (OHT) or early stage glaucoma. The mean follow-up time was 5.4 years; the average number of examinations was 7.7. The variability was described by the variance ratio VR. RESULTS: The HRT parameters showed very similar long-term fluctuations as the Octopus parameters. In detail: VR of HRT parameters ranged from 0.04 (cup area, cup volume, mean cup depth) to 0.35 (contour height variation), whereas VR of Octopus parameters ranged from 0.12 (mean sensitivity) to 0.15 (loss variance). CONCLUSIONS: The long-term variability of HRT parameters is in the same range as the long-term variability of visual field parameters. Since it is now widely accepted that visual field changes over time should be reproduced at least once or twice before clinical consequences can be drawn, the same should be postulated for HRT changes over time.

Endoscopically controlled erbium:YAG goniopuncture versus trabeculectomy: effect on intraocular pressure in combination with cataract surgery.

PURPOSE: . To compare the efficacy of endoscopic erbium:YAG laser goniopuncture in glaucoma treatment to trabeculectomy, both methods as adjuncts to cataract surgery. METHODS: . Fifty-nine eyes of 59 glaucoma patients with coexistent cataract were treated by phacoemulsification and endoscopic Er:YAG goniopuncture in a combined fashion. The primary study endpoints were intraocular pressure (IOP), number of antiglaucomatous drugs, postoperative complications, hospitalisation time and visual acuity at 1 year after surgery. To date, 24 eyes have finished the 1-year follow-up. This prospective treatment arm was compared to a retrospective inclusion-matched control group treated by trabeculectomy and cataract surgery in a single procedure. RESULTS: . In the laser-treated group, the mean IOP dropped by 30% from 23.4+/-3.7 mmHg to 16.3+/-6 mmHg ( P<0.0001) after 12 months. Without reoperation, treatment was successful in 71% of these eyes. In the control group, the IOP decreased by 33.5% from 22.7+/-3.3 mmHg to 15.1+/-3.8 mmHg ( P<0.0001). The success rate without reoperation was 46%. The number of antiglaucomatous drugs needed decreased from 1.48+/-0.95 to 0.48+/-0.7 ( P<0.0001) in the laser-treated group and from 2.0+/-0.9 to 0.39+/-0.6 ( P<0.0001) in the control group. Postoperative complications were found more frequently in the control group ( P<0.0001). Hospitalisation was shorter in the laser group ( P<0.0001). Postoperative visual acuity was lower in the control group ( P=0.004). CONCLUSION: . Combined Er:YAG goniopuncture and cataract surgery lowers the IOP to an extent comparable to combined trabeculectomy and cataract surgery. Due to fewer postoperative complications, Er:YAG goniopuncture seems to be superior to standard fistulation surgery as the primary approach within the first year.
