RESUMEN

PURPOSE: To perform a retrospective post hoc subgroup analysis of the FOCUS trial to assess the visual acuity outcomes and treatment benefits for patients receiving combination therapy who, at the time of enrollment, were naive to verteporfin photodynamic therapy (PDT) or had previously received PDT. METHODS: In this retrospective post hoc analysis of 24-month data from the FOCUS trial, PDT-naive and previously PDT-treated patients (n = 162) were included. Patients were randomized in a 2:1 ratio to receive 0.5 mg of ranibizumab monthly plus PDT or PDT alone. We retrospectively identified patients who had or had not received prior PDT for a post hoc subgroup analysis of 12- and 24-month outcomes. RESULTS: For the PDT-naive patients, mean change in the visual acuity at 24 months was +4.1 letters for the ranibizumab plus PDT group and -11.5 letters for the PDT monotherapy group, a treatment benefit over control group of 15.6 letters (95% confidence interval: 7.1-24.2). For the previously treated patients, mean change in the visual acuity at 24 months was +5.2 letters for the ranibizumab plus PDT group and -4.3 letters for the PDT monotherapy group, a treatment benefit over control group of 9.5 letters (95% confidence interval: 2.3-16.8). CONCLUSION: In the FOCUS subanalysis, the PDT-naive patients showed a trend toward greater treatment benefit over control subjects compared with patients previously treated with PDT. However, this study was not designed to address this question, and the confidence intervals were wide. Furthermore, the mean change in the visual acuity from baseline to 24 months was similar for both the PDT-naive and previously treated patients receiving combination therapy.

RESUMEN

RATIONALE: Higher rates of sepsis have been reported in minorities. OBJECTIVES: To explore racial differences in the incidence and associated case fatality of severe sepsis, accounting for clinical, social, health care service delivery, and geographic characteristics. METHODS: Retrospective population-based cohort study using hospital discharge and U.S. Census data for all persons (n = 71,102,655) living in 68 hospital referral regions in six states. MEASUREMENTS AND MAIN RESULTS: Age-, sex- and race-standardized severe sepsis incidence and inpatient case fatality rates, adjusted incidence rate ratios, and adjusted intensive care unit (ICU) admission and case fatality rate differences. Of 8,938,111 nonfederal hospitalizations, 282,292 had severe sepsis. Overall, blacks had the highest age- and sex-standardized population-based incidence (6.08/1,000 vs. 4.06/1,000 for Hispanics and 3.58/1,000 for whites) and ICU case fatality (32.1 vs. 30.4% for Hispanics and 29.3% for whites, P < 0.0001). Adjusting for differences in poverty in their region of residence, blacks still had a higher population-based incidence of severe sepsis (adjusted rate ratio, 1.44 [95% CI, 1.42-1.46]) than whites, but Hispanics had a lower incidence (adjusted rate ratio, 0.91 [0.90-0.92]). Among patients with severe sepsis admitted to the ICU, adjustments for clinical characteristics and the treating hospital fully explained blacks' higher ICU case fatality. CONCLUSIONS: Higher adjusted black incidence and the lower Hispanic incidence may reflect residual confounding, or it could signal biologic differences in susceptibility. Focused interventions to improve processes and outcomes of care at the hospitals that disproportionately treat blacks could narrow disparities in overall mortality from severe sepsis.

RESUMEN

PURPOSE: Smoking, age, and nutrition have been associated with the development of neovascular age-related macular degeneration (AMD) and can increase the risk of arterial thromboembolic events (ATEs). This study assesses annual rates of ATEs in new-onset neovascular AMD patients compared with matched controls. DESIGN: Retrospective study. PARTICIPANTS: New-onset neovascular AMD patients and age-, race-, gender-, and database length-matched controls from the 5% Medicare database. METHODS: We conducted a retrospective analysis of the 5% Medicare database from 2001 to 2003. New-onset neovascular AMD patients were included if they were > or =65 years old, had 2 diagnoses of neovascular AMD, and had at least 1 year of data before the first diagnosis of AMD within the dataset. A control group was constructed in a 3:1 ratio from those without a diagnosis of a major eye disorder and matched by age, race, gender, and length of data. Annual prevalence rates were determined for myocardial infarctions (MIs) and ischemic cerebral vascular accidents (CVAs). MAIN OUTCOME MEASURES: Rates of MIs and ischemic CVAs in new-onset neovascular AMD patients and matched controls from 2001 to 2003. RESULTS: There were 15771 new-onset neovascular AMD patients identified and matched with 46 408 controls. Average age was 80.5 years, with 64% > or =80; 65% were female; and 95.9% were white. Inpatient MI rates for neovascular AMD patients and controls were 2.2% and 2.2%, respectively (P = 0.74). Inpatient ischemic CVA rates for neovascular AMD patients and controls were 3.5% and 3.6%, respectively (P = 0.59). Myocardial infarction rates and ischemic CVA rates for both groups increased with age. Subgroups of patients with comorbidities known to be risk factors for ATEs (i.e., hypertension, hyperlipidemia, diabetes, and arrhythmias) had a higher rate of events. Patients with previous ATEs were also at a higher risk of subsequent events, at 7.4% for inpatient MI and 35.1% for inpatient ischemic stroke. CONCLUSION: Despite the shared risk factors associated with neovascular AMD and ATEs, Medicare beneficiaries with neovascular AMD had a rate of ATEs similar to that of matched controls. Rates of ATEs increased in patients with comorbidities and for patients with previous events.

RESUMEN

Drotrecogin alfa (activated) has been approved by the United States Food and Drug Administration for treatment of patients at high risk of death from severe sepsis. Severe sepsis is common, and its occurrence increases dramatically with age. Clinical use data, however, suggest that drotrecogin alfa (activated) may be underused in older patients, possibly due to concern over the drug's anticoagulant effects and perceived high cost. In addition, clinicians often treat older patients less aggressively than younger patients. We reviewed a subgroup analysis of patients aged 75 years and older from a large clinical trial evaluating efficacy and safety of drotrecogin alfa (activated), as well as cost-effectiveness data from real-world clinical use of the drug in older patients. We also explored ethical dilemmas of treating older patients with sepsis. Drotrecogin alfa (activated) is safe, effective, and cost-effective in older patients with severe sepsis and should be considered for elderly intensive care patients who are high risk of death and who have no contraindications to treatment.
