Retrospective Analysis to Describe Associations Between Tumor Necrosis Factor Alpha Inhibitors and COPD-Related Hospitalizations

Background: Limited information exists on the impact of tumor necrosis factor inhibition on COPD exacerbations. This retrospective study characterized this impact among COPD patients with underlying autoimmune conditions, exposed to tumor necrosis factor inhibitors (TNFi) and/or non-biologic disease-modifying antirheumatic drugs (DMARDs).Patients and methods: Adult COPD patients with ≥1 diagnosis for rheumatoid arthritis (RA), psoriasis (PsO), psoriatic arthritis (PsA), or ankylosing spondylitis (AS) before or within 6 months following the index COPD diagnosis were identified from the Truven Health MarketScan® databases. Patients were required to have a second claim for RA, PsO, PsA, AS, or DMARD use (biologic or non-biologic) prior to or up to 6 months following the index date. Incidence of COPD-related hospitalizations and emergency room (ER) visits was evaluated in relation to treatment with TNFi and/or DMARDs and other potential risk factors.Results: The study cohort included 40,687 patients (untreated, 37.7%; non-biologic DMARD, 35.4%; TNFi + non-biologic DMARD, 18%; TNFi, 8.8%). The proportion of patients with a COPD-related hospitalization and the incidence of COPD-related hospitalization (per 100 person-years) were lowest in the TNFi cohort (8.6%; 3.54, 95% confidence interval [CI]: 3.16–3.95) and the TNFi + non-biologic DMARD cohort (8.4%; 2.85, 95% CI: 2.63–3.08). In multivariate models, treatment with TNFi + non-biologic DMARD reduced the risk of COPD-related hospitalization or ER visits by 32% relative to non-biologic DMARDs (hazard ratio: 0.68; 95% CI: 0.61–0.75).Conclusion: In real-world settings, TNFi monotherapy confers similar risk for COPD-related hospitalization or ER visits as a non-biologic DMARD. Decreased risk was found among those treated with both TNFi and a non-biologic DMARD

Trends in AIDS-defining and non-AIDS-defining malignancies among HIV-infected patients: 1989-2002

In a comparison of rates of acquired immunodeficiency syndrome (AIDS)-defining malignancies (ADMs) for 1989-1996 versus 1997-2002, we found a decrease in ADMs (rate ratio, 0.31; P\u3c.0001) and a significant increase in non-AIDS-defining malignancies (non-ADMs; rate ratio, 10.87; P\u3c.0002). The mean CD4 cell count was lower among patients with ADMs than among those with non-ADMs. A longer duration of survival during highly active antiretroviral therapy might explain the increasing incidence of non-ADMs

Distribution of health care expenditures for HIV-infected patients

BACKGROUND: Health care expenditures for persons infected with human immunodeficiency virus (HIV) in the United State determined on the basis of actual health care use have not been reported in the era of highly active antiretroviral therapy. METHODS: Patients receiving primary care at the University of Alabama at Birmingham HIV clinic were included in the study. All encounters (except emergency room visits) that occurred within the University of Alabama at Birmingham Hospital System from 1 March 2000 to 1 March 2001 were analyzed. Medication expenditures were determined on the basis of 2001 average wholesale price. Hospitalization expenditures were determined on the basis of 2001 Medicare diagnostic related group reimbursement rates. Clinic expenditures were determined on the basis of 2001 Medicare current procedural terminology reimbursement rates. RESULTS: Among the 635 patients, total annual expenditures for patients with CD4+ cell counts \u3c50 cells/microL (36,533 dollars per patient) were 2.6-times greater than total annual expenditures for patients with CD4+ cell counts \u3e or =350 cells/microL (13,885 dollars per patient), primarily because of increased expenditures for nonantiretroviral medication and hospitalization. Expenditures for highly active antiretroviral therapy were relatively constant at approximately 10,500 dollars per patient per year across CD4+ cell count strata. Outpatient expenditures were 1558 dollars per patient per year; however, the clinic and physician component of these expenditures represented only 359 dollars per patient per year, or 2% of annual expenses. Health care expenditures for patients with HIV infection increased substantially for those with more-advanced disease and were driven predominantly by medication costs (which accounted for 71%-84% of annual expenses). CONCLUSIONS: Physician reimbursements, even with 100% billing and collections, are inadequate to support the activities of most clinics providing HIV care. These findings have important implications for the continued support of HIV treatment programs in the United States

Potential for non-combustible nicotine products to reduce socioeconomic inequalities in smoking: a systematic review and synthesis of best available evidence

While some experts have emphasised the potential for e-cigarettes to facilitate cessation among smokers with low socioeconomic status (SES), there is limited evidence of their likely equity impact. We assessed the potential for electronic cigarettes and other non-combustible nicotine-containing products (NCNPs) to reduce inequalities in smoking by systematically reviewing evidence on their use by SES in countries at stage IV of the cigarette epidemic

Therapy with Biologic Agents After Diagnosis of Solid Malignancies: Results from the Corrona Registry

OBJECTIVE: Guidelines suggest that rheumatoid arthritis (RA) patients with previously treated solid malignancy may be treated as patients without such history. The recommendation is based on limited evidence, and rheumatologists and patients are frequently hesitant to start or continue biologic therapy after a cancer diagnosis. The objective of this study was to describe biologic use in real-world patients with RA following a malignancy diagnosis. METHODS: RA patients enrolled in the Corrona registry and diagnosed with solid malignancy with at least 1 followup visit within 12 months after diagnosis were included in this analysis. The proportion of patients continuing or initiating biological/targeted synthetic disease-modifying antirheumatic drug (bDMARD/tsDMARD) after diagnosis was estimated. Median time to initiation of bDMARD/tsDMARD after diagnosis was calculated using the Kaplan-Meier method and the proportion initiating biologic treatment in 6-month time intervals was estimated using the life-table method. RESULTS: There were 880 patients who met inclusion criteria with 2585 person-years total followup time postdiagnosis. Of those, 367 (41.7%) were treated with bDMARD/tsDMARD within 12 months preceding malignancy, of whom 270 (30.7%) were taking such agents at first postdiagnosis visit. Forty-four (5%) switched biologic agents within 36 months and an additional 90 patients (10.2%) started a biologic. The majority of bDMARD/tsDMARD initiations during followup was a tumor necrosis factor inhibitor (TNFi; 53.5%). CONCLUSION: In real-world practice, nearly one-third of RA patients with a cancer diagnosis were treated with systemic therapy in the immediate visit after malignancy diagnosis and a considerable percentage of malignancy survivors initiated biologic therapy within 3 years. The majority of bDMARD/tsDMARD initiations post-malignancy diagnosis was a TNFi

Changes in Treatment Patterns in Patients with Psoriatic Arthritis Initiating Biologic and Nonbiologic Therapy in a Clinical Registry.

OBJECTIVE: Treatment options for psoriatic arthritis (PsA) have increased and improved in the past decade; treatment patterns in PsA remain poorly understood. Understanding current practices would aid in treatment management of patients with PsA. METHODS: This observational study was based on data from the Corrona registry of adult patients with PsA in North America collected between January 1, 2004, and December 31, 2012. Patients were divided among 3 therapy cohorts: tumor necrosis factor inhibitor (TNFi) monotherapy, methotrexate (MTX) monotherapy, and TNFi and MTX combination therapy. Patients were further divided among 3 study periods to understand changes over time: 2004-2006, 2007-2009, and 2010-2012. Data were collected on persistence, discontinuation, restarting, switching, adding/dropping therapy, and dose stretching. RESULTS: This study included 520 patients: 190 TNFi monotherapy, 217 MTX monotherapy, and 113 combination therapy; 110 from 2004 to 2006, 192 from 2007 to 2009, and 218 from 2010 to 2012. Over time, the proportion of patients initiating TNFi monotherapy decreased, while the proportion initiating combination therapy remained constant. The percentage of patients who were persistent decreased over time across all therapy cohorts, but remained higher in TNFi monotherapy than in other cohorts. Duration of persistence decreased over time. Patients initiating MTX monotherapy were more likely than their TNFi counterparts to add therapy. CONCLUSION: Treatment patterns in patients with PsA have changed from 2004 to 2012. Physicians are not more likely to initiate TNFi monotherapy, although clinical evidence supporting its effectiveness has increased over this study period, and patients remain more persistent with it
