Treatment Patterns and Effectiveness of Tofacitinib in Patients Initiating Therapy for Rheumatoid Arthritis: Results From the CorEvitas Rheumatoid Arthritis Registry.

OBJECTIVE: This real-world analysis assessed baseline demographics/characteristics and treatment patterns/effectiveness in patients with rheumatoid arthritis (RA) initiating tofacitinib (TOF) in the US CorEvitas RA Registry. METHODS: The primary analysis of this study included patients with RA initiating TOF with a 12-month follow-up visit from November 2012 to January 2021. Outcomes included baseline demographics/characteristics and TOF initiation/discontinuation reasons, treatment patterns, and effectiveness (disease activity and patient-reported outcomes [PROs] at 12 months); the primary effectiveness outcome was Clinical Disease Activity Index low disease activity (CDAI LDA). All data, analyzed descriptively, were stratified by TOF regimen (monotherapy vs combination therapy), line of therapy (second- to fourth-line), time of initiation (2012-2014, 2015-2017, or 2018-2020), and dose (5 mg twice daily vs 11 mg once daily). RESULTS: Of 2874 patients with RA who initiated TOF, 1298 had a qualifying 12-month follow-up visit; of these, 43.1% were monotherapy and 66.5% were fourth-line therapy. Overall, tumor necrosis factor inhibitors (40.8%) were the most common treatment immediately prior to TOF initiation. The most common reason for TOF initiation (among those with a reason) was lack/loss of efficacy of prior treatment (67.7%). Overall, at 12 months, 31.9% and 10.1% had achieved CDAI LDA and remission, respectively; 22.4%, 10.4%, and 5% had achieved ≥ 20%, ≥ 50%, and ≥ 70% improvement in modified American College of Rheumatology core set measures, respectively; and improvements in PROs were observed. Effectiveness was generally similar across TOF stratifications. CONCLUSION: TOF effectiveness (CDAI LDA) was observed in a US real-world setting of patients with RA regardless of TOF regimen, line of therapy, time of initiation, and dose.

Comparative effectiveness of abatacept versus TNF inhibitors in rheumatoid arthritis patients who are ACPA and shared epitope positive.

BACKGROUND: The HLA-DRB1 shared epitope (SE) is a risk factor for the development of rheumatoid arthritis (RA) and the production of anti-citrullinated protein antibodies (ACPAs) in RA patients. Our objective was to examine the real-world effectiveness of abatacept versus tumor necrosis factor inhibitors (TNFi) in patients with RA who were SE and anti-cyclic citrullinated peptide antibody (anti-CCP3) positive. METHODS: Abatacept or TNFi initiators who were SE + and anti-CCP3+ (> 20 U/mL) at or prior to treatment and had moderate or high CDAI score (> 10) at initiation were identified. The primary outcome was mean change in CDAI score over six months. Analyses were conducted in propensity score (PS)-trimmed and -matched populations overall and a biologic-experienced subgroup. Mixed-effects models were used. RESULTS: In the overall PS-trimmed (abatacept, n = 170; TNFi, n = 157) and PS-matched cohorts (abatacept, n = 111; TNFi, n = 111), there were numerically greater improvements in mean change in CDAI between abatacept and TNFi but were not statistically significant. Similar trends were seen for biologic-experienced patients, except that statistical significance was reached for mean change in CDAI in the PS-trimmed cohort (abatacept, 12.22 [95% confidence interval (95%CI) 10.13 to 14.31]; TNFi, 9.28 [95%CI 7.08 to 11.48]; p = 0.045). CONCLUSION: In this real world cohort, there were numerical improvements in efficacy outcomes with abatacept over TNFi in patients with RA who were SE + and ACPA+, similar to results from a clinical trial population The only statistically significant finding after adjusting for covariates was greater improvement in CDAI with abatacept versus TNFi in the bio-experienced PS-trimmed cohort..

Brentuximab vedotin with AVD for stage II-IV HIV-related Hodgkin lymphoma (AMC 085): phase 2 results from an open-label, single arm, multicentre phase 1/2 trial.

BACKGROUND: Brentuximab vedotin in combination with doxorubicin, vinblastine, and dacarbazine (AVD) is approved in the upfront setting for advanced stage classical Hodgkin lymphoma (cHL). People living with HIV have been excluded from these studies. We aimed to understand the activity and safety of brentuximab vedotin-AVD in people living with HIV diagnosed with Hodgkin lymphoma, while focusing on HIV disease parameters and antiretroviral therapy (ART) interactions. METHODS: We present the phase 2 portion of a multicentre phase 1/2 study. Eligible patients were 18 years or older, had untreated stage II-IV HIV-associated cHL (HIV-cHL), a Karnofsky performance status of more than 30%, a CD4+ T-cell count of 50 cells per µL or more, were required to take ART, and were not on strong CYP3A4 or P-glycoprotein inhibitors. Patients were treated intravenously with 1·2 mg/kg of brentuximab vedotin (recommended phase 2 dose) with standard doses of AVD for six cycles on days 1 and 15 of a 28-day cycle. The primary endpoint of the phase 2 portion was 2-year progression-free survival (PFS), assessed in all eligible participants who began treatment. Accrual has been completed. This trial is registered at ClinicalTrials.gov, NCT01771107. FINDINGS: Between March 8, 2013, and March 7, 2019, 41 patients received study therapy with a median follow up of 29 months (IQR 16-38). 34 (83%) of 41 patients presented with stage III-IV and seven (17%) with stage II unfavourable HIV-cHL. 37 (90%) of 41 patients completed therapy, all 37 of whom achieved complete response. The 2-year PFS was 87% (95% CI 71-94) and the overall survival was 92% (78-97). The most common grade 3 or worse adverse events were peripheral sensory neuropathy (four [10%] of 41 patients), neutropenia (18 [44%]), and febrile neutropenia (five [12%]). One treatment-related death was reported, due to infection. INTERPRETATION: Brentuximab vedotin-AVD was highly active and had a tolerable adverse event rate in HIV-cHL and is an important therapeutic option for people with HIV-cHL. The complete reponse rate is encouraging and is possibly related to a unique aspect of HIV-cHL biology. Upcoming 5-year data will evaluate the sustainability of the outcomes obtained.

Characteristics of Patients with Crohn's Disease With or Without Perianal Fistulae in the CorEvitas Inflammatory Bowel Disease Registry.

BACKGROUND: There are limited real-world data characterizing perianal fistulae in patients with Crohn's disease (CD). AIM: To describe characteristics of patients with CD with and without perianal fistulae. METHODS: In this cross-sectional study, characteristics, treatment history, and health outcomes of patients with CD enrolled in the CorEvitas IBD Registry were described according to perianal fistula status (current/previous or none). RESULTS: Eight hundred and seventy-eight patients were included. Compared with patients with no perianal fistulae (n = 723), patients with current/previous perianal fistulae (n = 155) had longer disease duration since CD diagnosis (mean 16.5 vs 12.3 years; difference 4.3 years; 95% CI, 2.0, 6.6) and fewer had Harvey-Bradshaw Index scores indicative of remission (0-4, 56.8% vs 69.6%; difference - 12.9%; 95% CI, - 21.6, - 4.2). More patients with current/previous fistulae reported a history of IBD-related emergency room visits (67.7% vs 56.1%; difference 11.6%; 95% CI, 3.4, 19.8), hospitalizations (76.1% vs 58.4%; difference 17.7%; 95% CI, 10.1, 25.4), and surgeries (59.4% vs 27.7%; difference 31.7%; 95% CI, 23.3, 40.1), and a history of treatment with tumor necrosis factor inhibitors (81.3% vs 60.7%; difference 20.6%; 95% CI, 13.5, 27.7), immunosuppressants (51.6% vs 31.2%; difference 20.4%; 95% CI, 11.9, 29.0), and antibiotics (50.3% vs 23.7%; difference 26.6%; 95% CI, 18.2, 35.1) than patients without perianal fistulae. CONCLUSIONS: Patients with CD with current/previous perianal fistulae have more symptomatic experiences of disease, higher medication use, hospitalization rates, and emergency room visits than patients without perianal fistulae. Interventions to prevent/reduce risk of developing fistulae may help improve outcomes in CD.

Safety and Tolerability of Carboplatin and Paclitaxel in Cancer Patients with HIV (AMC-078), an AIDS Malignancy Consortium (AMC) Study.

BACKGROUND: Persons living with human immunodeficiency virus are an underserved population for evidence-based cancer treatment. Paclitaxel and carboplatin (PCb) is an active regimen against a variety of solid tumors, including several seen in excess in patients with HIV infection. We performed a pilot trial to evaluate the safety of full-dose PCb in people living with human immunodeficiency virus and cancer. METHODS: Eligible patients, stratified by concurrent antiretroviral therapy (ART) that included CYP3A4 inhibitors or not, received paclitaxel (175 mg/m2) in combination with carboplatin (target AUC 6) intravenously every 3 weeks for up to 6 cycles. RESULTS: Sixteen evaluable patients received 64 cycles of PCb, including 6 patients treated with CYP3A4 inhibiting ART (ritonavir). The adverse event profile was consistent with the known toxicity profile of PCb, with no differences between the 2 strata. There were 4 partial responses (25%, 95% CI: 7%-52%), and overall, CD4+ lymphocyte count was similar after completion of therapy (median: 310/µL) compared with baseline values (median: 389/µL). Pharmacokinetic studies in 6 patients revealed no significant differences in Cmax or AUCinf for paclitaxel between the 2 cohorts. CONCLUSION: Full doses of PCb chemotherapy are tolerable when given concurrently with ART in people living with human immunodeficiency virus with cancer, including patients receiving CYP3A4 inhibitors.

AMC-070: Lenalidomide Is Safe and Effective in HIV-Associated Kaposi Sarcoma.

PURPOSE: Kaposi sarcoma (KS), an endothelial cell tumor associated with KS herpesvirus (KSHV), remains among the most common malignancies occurring with HIV infection (HIV-KS). As an oral anti-inflammatory, antiangiogenic, and immunomodulatory agent, lenalidomide is potentially an attractive alternative to standard chemotherapy for KS. EXPERIMENTAL DESIGN: The primary objectives of this phase I/II trial were to determine the maximum tolerated dose (MTD) and response rates for lenalidomide in HIV-KS. Secondary objectives included correlating response with natural killer (NK) and T-cell subsets, plasma cytokines, viral copy number, and KSHV gene expression in biopsies. Four dose levels of oral lenalidomide taken 21 consecutive days of 28-day cycles were evaluated in adults with HIV-KS on antiretroviral therapy with controlled viremia. RESULTS: Fifteen and 23 participants enrolled in phases I and II, respectively, 76% of whom had received prior KS therapy. The MTD was not reached, declaring 25 mg as the recommended phase II dose (RP2D). The most frequent adverse events were neutropenia, fatigue, leukopenia, and diarrhea. Of the 25 evaluable participants receiving RP2D, 60% responded. Correlative studies performed in a subset of participants demonstrated a significant increase in proportions of blood T cells with T-regulatory phenotype, and plasma cytokines trended toward a less inflammatory pattern. Clinical response was associated with loss of KSHV transcription. CONCLUSIONS: Lenalidomide is active in HIV-KS. The most common adverse events were manageable. With 60% of participants receiving RP2D obtaining a partial response and <10% discontinuing due to adverse events, the response and tolerability to lenalidomide support its use in HIV-KS.

Impact of Myc in HIV-associated non-Hodgkin lymphomas treated with EPOCH and outcomes with vorinostat (AMC-075 trial).

EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin) is a preferred regimen for HIV-non-Hodgkin lymphomas (HIV-NHLs), which are frequently Epstein-Barr virus (EBV) positive or human herpesvirus type-8 (HHV-8) positive. The histone deacetylase (HDAC) inhibitor vorinostat disrupts EBV/HHV-8 latency, enhances chemotherapy-induced cell death, and may clear HIV reservoirs. We performed a randomized phase 2 study in 90 patients (45 per study arm) with aggressive HIV-NHLs, using dose-adjusted EPOCH (plus rituximab if CD20+), alone or with 300 mg vorinostat, administered on days 1 to 5 of each cycle. Up to 1 prior cycle of systemic chemotherapy was allowed. The primary end point was complete response (CR). In 86 evaluable patients with diffuse large B-cell lymphoma (DLBCL; n = 61), plasmablastic lymphoma (n = 15), primary effusion lymphoma (n = 7), unclassifiable B-cell NHL (n = 2), and Burkitt lymphoma (n = 1), CR rates were 74% vs 68% for EPOCH vs EPOCH-vorinostat (P = .72). Patients with a CD4+ count <200 cells/mm3 had a lower CR rate. EPOCH-vorinostat did not eliminate HIV reservoirs, resulted in more frequent grade 4 neutropenia and thrombocytopenia, and did not affect survival. Overall, patients with Myc+ DLBCL had a significantly lower EFS. A low diagnosis-to-treatment interval (DTI) was also associated with inferior outcomes, whereas preprotocol therapy had no negative impact. In summary, EPOCH had broad efficacy against highly aggressive HIV-NHLs, whereas vorinostat had no benefit; patients with Myc-driven DLBCL, low CD4, and low DTI had less favorable outcomes. Permitting preprotocol therapy facilitated accruals without compromising outcomes. This trial was registered at www.clinicaltrials.gov as #NCT0119384.

Novel isomeric metabolite profiles correlate with warfarin metabolism phenotype during maintenance dosing in a pilot study of 29 patients.

: For this pilot study, we leveraged metabolite patterns for warfarin patients to more accurately assess clinically relevant differences in drug metabolism. We tested our hypothesis that plasma metabolite levels correlate with the influence of clinical factors on R-warfarin and S-warfarin metabolism (warfarin metabolic phenotype). We recruited 29 patients receiving a maintenance dose and testing within targeted therapeutic range. We determined their CYP2C9 and vitamin K epoxide reductase genotype and profiled 14 isomeric forms of warfarin and its metabolites. We employed three novel types of clearance ratios using analyte levels to perform multiple-linear regression analyses with clinical factors impacting drug metabolism and dose-responses. Competitive clearance ratios correlated with seven clinical factors including lifestyle choices (smoking), genetics (CYP2C9 and vitamin K epoxide reductase 1), and drug interactions (omeprazole) along with age, weight, and malignancy. Significant competitive clearance ratio correlations (P = 0.04 to < 0.001) explained 21-95% variability. Their performances surpassed that of oxidative and metabolic clearance ratios based on the number and significance of correlations. Competitive clearance ratios may accurately assess significance of factors on maintaining levels of pharmacologically active forms of the drug and metabolites related to dose-responses and thus provide a strategy to minimize adverse events and improve safety during anticoagulant therapy. This unique capacity could provide a strategy in a future, higher power study with a larger cohort of patients to more accurately assess the significance of clinical factors on active drug levels contributing to warfarin dose-responses.

Safety and Preliminary Efficacy of Vorinostat With R-EPOCH in High-risk HIV-associated Non-Hodgkin's Lymphoma (AMC-075).

INTRODUCTION: Vorinostat (VOR), a histone deacetylase inhibitor, enhances the anti-tumor effects of rituximab (R) and cytotoxic chemotherapy, induces viral lytic expression and cell killing in Epstein-Barr virus-positive (EBV+) or human herpesvirus-8-positive (HHV-8+) tumors, and reactivates latent human immunodeficiency virus (HIV) for possible eradication by combination antiretroviral therapy (cART). PATIENTS AND METHODS: We performed a phase I trial of VOR given with R-based infusional EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin hydrochloride) (n = 12) and cART in aggressive HIV-associated B-cell non-Hodgkin lymphoma (NHL) in order to identify safe dosing and schedule. VOR (300 or 400 mg) was given orally on days 1 to 5 with each cycle of R-EPOCH for 10 high-risk patients with diffuse large B-cell lymphoma (1 EBV+), 1 EBV+/HHV-8+ primary effusion lymphoma, and 1 unclassifiable NHL. VOR was escalated from 300 to 400 mg using a standard 3 + 3 design based on dose-limiting toxicity observed in cycle 1 of R-EPOCH. RESULTS: The recommended phase II dose of VOR was 300 mg, with dose-limiting toxicity in 2 of 6 patients at 400 mg (grade 4 thrombocytopenia, grade 4 neutropenia), and 1 of 6 treated at 300 mg (grade 4 sepsis from tooth abscess). Neither VOR, nor cART regimen, significantly altered chemotherapy steady-state concentrations. VOR chemotherapy did not negatively impact CD4+ cell counts or HIV viral loads, which decreased or remained undetectable in most patients during treatment. The response rate in high-risk patients with NHL treated with VOR(R)-EPOCH was 100% (complete 83% and partial 17%) with a 1-year event-free survival of 83% (95% confidence interval, 51.6%-97.9%). CONCLUSION: VOR combined with R-EPOCH was tolerable and seemingly efficacious in patients with aggressive HIV-NHL.

Feasibility Test of a Community-Relevant Intervention Designed to Promote African American Participation in Translational, Breast Cancer Disparities Research: Know About Health Options for Women (Know HOW).

There are marked racial differences in breast cancer, the second leading cause of death among US women. Understanding the causes of these differences is essential to eliminate breast cancer inequities. More prevalent in African American than in Caucasian women, metabolic syndrome has been associated with breast cancer outcomes. Further research is needed to understand metabolic syndrome's role in breast cancer disparities, thus novel strategies to increase minority participation in research are important. We embedded two approaches (comprehensive, focused) to increase African American participation in breast cancer research in a state-wide service program and pilot tested both approaches in rural African American women. We conducted three comprehensive and three focused outreach programs (n = 48) and assessed research participation through consent and actual provision of data for four types of data: survey, anthropometric, blood, and mammography records. The majority of participants provided written consent for all data collection procedures (96 % survey; 92 % anthropometric; 94 %, blood; 100 % mammography). There were no between group differences in consent rates. There was variation in the overall proportion of participants who provided data (96 % survey; 92 % anthropometric; 73 % blood; 40 % mammography). Women in the comprehensive approach were less likely to return for a scheduled mammogram than women in the focused approach (19 % vs 64 %, p = 0.0236). Both outreach programs promoted African American engagement in research. Differences in the provision of data by type may have been due to participant burden (i.e., time required to provide data). Study designs that embed research in service programs have promise to increase minority research participation.

Brentuximab vedotin with AVD shows safety, in the absence of strong CYP3A4 inhibitors, in newly diagnosed HIV-associated Hodgkin lymphoma.

OBJECTIVE: Brentuximab vedotin is a Food and Drug Administration approved anti-CD30 antibody drug conjugate potently active in Hodgkin lymphoma. Trials of brentuximab vedotin with doxorubicin, vinblastine, and dacarbazine (AVD-BV) excluded patients with HIV. We studied the safety of AVD-BV in newly diagnosed HIV-associated classical Hodgkin lymphoma . DESIGN AND METHODS: Patients diagnosed with stage II-IV HIV-associated classical Hodgkin lymphoma received AVD-BV on days 1 and 15 every 28 days for six cycles. Anti-HIV medications with strong CYP3A4 inhibition were excluded. This phase 1 trial followed a 3+3 dose de-escalation design started with brentuximab vedotin at 1.2 mg/kg with standard dosing of AVD. Dose-limiting toxicities were defined in cycle one. RESULTS: Seven patients were enrolled with six being evaluable: five of six stage III/IV, three with an international prognostic score at least 4. With no dose-limiting toxicities identified, all six were treated at the 1.2 mg/kg dose. Only five grade (G) three nonhematological adverse events were noted in three patients: pulmonary infection, diarrhea, and peripheral neuropathy. No G4/5 adverse events occurred. PET/computer tomography was negative in five of six after cycle 2 and six of six post therapy. Progression-free survival was 100% at 25 months with all patients in remission. One patient was deemed ineligible for taking ritonavir, a strong CYP3A4 inhibitor, but developed G3/4 adverse events including febrile neutropenia, and pancreatitis and though consented was excluded from all evaluation. CONCLUSION: AVD-BV was well tolerated at recommended phase 2 dose of 1.2 mg/kg. Concurrent strong CYP3A4 inhibitors should be avoided. A phase 2 study of AVD-BV is currently enrolling (NCT01771107).

A phase 1/pharmacokinetic study of sunitinib in combination with highly active antiretroviral therapy in human immunodeficiency virus-positive patients with cancer: AIDS Malignancy Consortium trial AMC 061.

BACKGROUND: The treatment of non-acquired immunodeficiency syndrome-defining cancers may be complicated by drug interactions between highly active antiretroviral therapy (HAART) and chemotherapy. This trial is the first by the AIDS Malignancy Consortium to assess targeted therapies and HAART in human immunodeficiency virus-positive patients (ClinicalTrials.gov identifier: NCT00890747). METHODS: In a modified phase 1 study of sunitinib, patients were stratified into 2 treatment arms based on whether they were receiving therapy with ritonavir, a potent CYP3A4 inhibitor. Patients in treatment arm 1 (non-ritonavir HAART) received standard sunitinib dosing (50 mg/day). Treatment arm 2 (ritonavir-based HAART) used a phase 1, 3 + 3 dose escalation design (from 25 mg/day to 50 mg/day). Cycles were comprised of 4 weeks on treatment followed by a 2-week break (6 weeks total). The pharmacokinetics of sunitinib and its active metabolite (N-desethyl sunitinib) were assessed. RESULTS: Nineteen patients were enrolled and were evaluable. Patients on treatment arm 1 tolerated treatment with no dose-limiting toxicity observed. In treatment arm 2, a dose-limiting toxicity was experienced at a dose of 37.5 mg, and an additional 3 of 5 patients experienced grade 3 neutropenia (toxicity graded as per National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.0]), an uncommon toxicity of sunitinib. No patient achieved a response, but 10 patients had stable disease, including 8 with prolonged disease stability. Efavirenz, a potent inducer of CYP3A4, resulted in increased exposure of N-desethyl sunitinib, whereas ritonavir caused decreased exposure of the metabolite. Hand-foot syndrome was associated with higher steady-state trough concentrations of sunitinib. CONCLUSIONS: Patients receiving non-ritonavir-based HAART regimens tolerated standard dosing of sunitinib. Patients receiving ritonavir-based therapy who were treated with a dose of 37.5 mg/day experienced higher toxicities. Dose reductions of sunitinib to 37.5 mg may be warranted in patients receiving ritonavir.

Treatment assignment guesses by study participants in a double-blind dose escalation clinical trial of saw palmetto.

OBJECTIVES: This report assesses participant perception of treatment assignment in a randomized, double-blind, placebo-controlled trial of saw palmetto for the treatment of benign prostatic hyperplasia (BCM). DESIGN: Participants randomized to receive saw palmetto were instructed to take one 320 mg gelcap daily for the first 24 weeks, two 320 mg gelcaps daily for the second 24 weeks, and three 320 mg gelcaps daily for the third 24 weeks. Study participants assigned to placebo were instructed to take the same number of matching placebo gelcaps in each time period. At 24, 48, and 72 weeks postrandomization, the American Urological Association Symptom Index (AUA-SI) was administered and participants were asked to guess their treatment assignment. SETTINGS: The study was conducted at 11 clinical centers in North America. PARTICIPANTS: Study participants were men, 45 years and older, with moderate to low severe BPH symptoms, randomized to saw palmetto (N=151) or placebo (N=155). OUTCOME MEASURES: Treatment arms were compared with respect to the distribution of participant guesses of treatment assignment. RESULTS: For participants assigned to saw palmetto, 22.5%, 24.7%, and 29.8% correctly thought they were taking saw palmetto, and 37.3%, 40.0%, and 44.4% incorrectly thought they were on placebo at 24, 48, and 72 weeks, respectively. For placebo participants, 21.8%, 27.4%, and 25.2% incorrectly thought they were on saw palmetto, and 41.6%, 39.9%, and 42.6% correctly thought they were on placebo at 24, 48, and 72 weeks, respectively. The treatment arms did not vary with respect to the distributions of participants who guessed they were on saw palmetto (p=0.823) or placebo (p=0.893). Participants who experienced an improvement in AUA-SI were 2.16 times more likely to think they were on saw palmetto. CONCLUSIONS: Blinding of treatment assignment was successful in this study. Improvement in BPH-related symptoms was associated with the perception that participants were taking saw palmetto.

Cochlear implant failure, revision, and reimplantation.

OBJECTIVE: To evaluate the long-term adverse cochlear implant (CI) outcomes resulting in revision surgery including CI reimplantation (CIR). PATIENTS: Pediatric and adult patients requiring revision procedures after CI placement. INTERVENTION(S): Revision surgery on cochlear implant patients. MAIN OUTCOME MEASURES: Device type, length of total device follow-up, time to device failure, cause for failure, peak pre-CIR and post-CIR audiometric performance, rate of surgical site complications, and operative findings. RESULTS: A total of 317 patients, receiving 439 CIs between January 2000 and April 2012, met inclusion criteria for this series. For the patients implanted at our institution, the revision surgery rate was 4.1%, with a CIR rate of 3.0%. The CIR rates among the pediatric and adult populations were 5.0% and 1.3%, respectively (p = 0.0336). The rate of revision procedures because of failed fixation or device extrusion was 0.9%. Device failure was experienced in 8 patients in our series, with 75% occurring with the CI24R (CS) device. CONCLUSION: All reimplanted patients with available data had good audiometric outcomes, with the exception of those reimplanted for soft failure who had poor immediate auditory function. Using the manufacturers' recommended surgical technique, including drilling a bony recess with suture fixation, very low surgical revision rates were achieved. Pediatric patients experienced significantly higher complications requiring CIR. All hard failures in this series occurred in the pediatric group and in a single device. Continued follow-up will be needed to determine if additional devices will succumb to this mode of failure.

Do HIV-infected non-small cell lung cancer patients receive guidance-concordant care?

BACKGROUND: The incidence of lung cancer cases among HIV-infected individuals is increasing with time. It is unclear whether HIV-infected individuals receive the same care for lung cancer as immunocompetent patients because of comorbidities, the potential for interaction between antiretroviral agents and cancer chemotherapy, and concerns regarding complications related to treatment or infection. OBJECTIVES: The objective of this study was to assess the effect of HIV infection on receipt of guidance-concordant care, and its impact on overall survival among non-small cell lung cancer Medicare beneficiaries. DESIGN: The study design was a matched case-control design where each HIV patient was matched by age group, sex, race, and lung cancer stage at diagnosis with 20 controls randomly selected among those who were not HIV infected. SUBJECTS: The patients included in this study were Medicare beneficiaries diagnosed with non-small cell lung cancer between 1998 and 2007, who qualified for Medicare on the basis of age and were 65 years of age or older at the time of lung cancer diagnosis. HIV infection status was based on Medicare claims data. A total of 174 HIV cases and 3480 controls were included in the analysis. MEASURES: Odds ratios for receiving guidance-concordant care and hazard ratios for overall survival were estimated. RESULTS: HIV infection was not independently associated with the receipt of guidance-concordant care. Among stage I/II patients, median survival times were 26 and 43 months, respectively, for those with and without HIV infection (odds ratio=1.48, P=0.021). CONCLUSIONS: HIV infection was not associated with receipt of guidance-concordant care but reduced survival in early-stage patients.

Geographic variability in human papillomavirus vaccination among U.S. young women.

BACKGROUND: Little information is available on geographic disparity of human papillomavirus (HPV) vaccination among women aged 18-26 years in the U.S. Genital HPV is the most common sexually transmitted infection in the U.S. Persistent HPV infection with oncogenic types can cause cervical cancer. PURPOSE: This study utilized data collected from the 2010 National Health Interview Survey (NHIS). It identified geographic variability and other factors contributing to the disparities in HPV vaccine series initiation in a nationally representative sample of women aged 18-26 years. METHODS: The study utilized data collected from 1867 women who participated in the Cancer Control Module Supplement of the 2012 NHIS. A multivariable logistic regression model was used to assess characteristics associated with initiation of the HPV series. Analyses were performed in 2012. RESULTS: After adjusting for other characteristics, women living in the West and North Central/Midwest had 54% and 20% greater odds of initiating the HPV series, respectively, compared with those living in the Northeast. Other factors associated with HPV series initiation were younger age, Hispanic background, being single/never married, childlessness, a history of HPV, and current alcohol use. Factors correlated with failure to initiate the HPV series were: not having insurance, living below the 200% poverty level, not being a high school graduate, not currently using hormone-based birth control, most recent Pap >1 year ago, no regular provider, last clinic visit ≥12 months ago, and never having received the hepatitis B vaccine. CONCLUSIONS: Results demonstrate disparity in HPV vaccine uptake by region of residence in the U.S. among young women. Further research is needed to understand the factors contributing to this geographic disparity. Evaluation of vaccination policies and practices associated with higher coverage regions might help characterize effective methods to improve HPV vaccination among women aged 18-26 years.

Outcomes of cartilage tympanoplasty in the pediatric population.

OBJECTIVE: To justify the successful use of a patient selection algorithm based on age for primary cartilage tympanoplasty. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care pediatric hospital. SUBJECTS AND METHODS: We performed a retrospective chart review of patients between ages 4 and 13 years who underwent cartilage tympanoplasty for tympanic membrane perforations from August 2005 to November 2011. Demographics, complication data, and auditory outcomes were collected. RESULTS: Patients were subdivided into 3 age groups. Group 1 consisted of patients younger than 7 years (n = 43); group 2, ages 7 to 10 years (n = 40); and group 3, ages 10 to 13 years (n = 36). Mean follow-up was 595 days (range, 48-1742). Complication rates respective to the 3 groups were as follows: remnant perforation (6.97%, 5.00%, 2.78%), revision tympanoplasty (2.33%, 2.50%, 0%), and need for tympanostomy tubes (4.65%, 2.50%, 0%). Logistic regression models were used to evaluate complication rates between groups. No significant differences were found (remnant perforation, P = .710; repeat tympanoplasty, P = .998; tympanostomy tubes, P = .875). No significance was found among audiological outcomes between the 3 groups. CONCLUSION: These data suggest cartilage tympanoplasty can be performed effectively in young children when appropriate conditions exist.

Patterns of failure in canal wall down mastoidectomy cavity instability.

OBJECTIVE: To evaluate patterns of failure for canal wall down mastoid cavities requiring surgical revision. STUDY DESIGN: Retrospective review. SETTING: Academic tertiary referral center PATIENTS: Adults and children that underwent revision of an unstable open mastoid cavity from 1995 to 2010. INTERVENTION(S): Review of demographic data, tympanomastoid pathology, and plausible risk factors for an unstable cavity. Available computed tomography (CT) scans were reviewed for indicators of suboptimal cavity shape. Spearman's correlation analysis was undertaken. Findings were classified as Type 1 (primary tympanomastoid pathology), Type 2 (cavity shape/size), or Type 3 (negative host environment). MAIN OUTCOME MEASURE(S): Frequency of risk factors and correlation. RESULTS: Approximately 130 cases were reviewed. Stapes erosion (49.2%), absent malleus (26.2%), cholesteatoma (44.6%), tympanic membrane perforation (34.6%), and fibrotic middle ear mucosa (20.8%) were common. CT scans often demonstrated an intact open mastoid tip (87.5%) and a high facial ridge (54.2%). Notable correlations were discovered between the facial ridge height proximally and the height distally (r = 0.46437, p = 0.0256) and tympanic membrane perforation and absent malleus (r = -0.17944, p = 0.0419). Approximately 68% of the subjects had at least 1 Class 1 risk factor present among cholesteatoma, tympanic membrane perforation/atelectasis, and extruded prosthesis. All CT scans reviewed demonstrated at least 1 class 2 factor. CONCLUSION: Although primary tympanomastoid pathology is quite common, some aspect of suboptimal mastoid cavity size and shape is pervasive. Correlation analysis suggests that surgeons tend to either lower the facial ridge completely or not at all and that an absent malleus seems to be associated with a tympanic membrane perforation.
