RESUMEN

BACKGROUND: Although clinicians have traditionally used the Finnegan Neonatal Abstinence Scoring Tool to assess the severity of neonatal opioid withdrawal, a newer function-based approach - the Eat, Sleep, Console care approach - is increasing in use. Whether the new approach can safely reduce the time until infants are medically ready for discharge when it is applied broadly across diverse sites is unknown. METHODS: In this cluster-randomized, controlled trial at 26 U.S. hospitals, we enrolled infants with neonatal opioid withdrawal syndrome who had been born at 36 weeks' gestation or more. At a randomly assigned time, hospitals transitioned from usual care that used the Finnegan tool to the Eat, Sleep, Console approach. During a 3-month transition period, staff members at each hospital were trained to use the new approach. The primary outcome was the time from birth until medical readiness for discharge as defined by the trial. Composite safety outcomes that were assessed during the first 3 months of postnatal age included in-hospital safety, unscheduled health care visits, and nonaccidental trauma or death. RESULTS: A total of 1305 infants were enrolled. In an intention-to-treat analysis that included 837 infants who met the trial definition for medical readiness for discharge, the number of days from birth until readiness for hospital discharge was 8.2 in the Eat, Sleep, Console group and 14.9 in the usual-care group (adjusted mean difference, 6.7 days; 95% confidence interval [CI], 4.7 to 8.8), for a rate ratio of 0.55 (95% CI, 0.46 to 0.65; P<0.001). The incidence of adverse outcomes was similar in the two groups. CONCLUSIONS: As compared with usual care, use of the Eat, Sleep, Console care approach significantly decreased the number of days until infants with neonatal opioid withdrawal syndrome were medically ready for discharge, without increasing specified adverse outcomes.

RESUMEN

BACKGROUND: The incidence of anal cancer is substantially higher among persons living with the human immunodeficiency virus (HIV) than in the general population. Similar to cervical cancer, anal cancer is preceded by high-grade squamous intraepithelial lesions (HSILs). Treatment for cervical HSIL reduces progression to cervical cancer; however, data from prospective studies of treatment for anal HSIL to prevent anal cancer are lacking. METHODS: We conducted a phase 3 trial at 25 U.S. sites. Persons living with HIV who were 35 years of age or older and who had biopsy-proven anal HSIL were randomly assigned, in a 1:1 ratio, to receive either HSIL treatment or active monitoring without treatment. Treatment included office-based ablative procedures, ablation or excision under anesthesia, or the administration of topical fluorouracil or imiquimod. The primary outcome was progression to anal cancer in a time-to-event analysis. Participants in the treatment group were treated until HSIL was completely resolved. All the participants underwent high-resolution anoscopy at least every 6 months; biopsy was also performed for suspected ongoing HSIL in the treatment group, annually in the active-monitoring group, or any time there was concern for cancer. RESULTS: Of 4459 participants who underwent randomization, 4446 (99.7%) were included in the analysis of the time to progression to cancer. With a median follow-up of 25.8 months, 9 cases were diagnosed in the treatment group (173 per 100,000 person-years; 95% confidence interval [CI], 90 to 332) and 21 cases in the active-monitoring group (402 per 100,000 person-years; 95% CI, 262 to 616). The rate of progression to anal cancer was lower in the treatment group than in the active-monitoring group by 57% (95% CI, 6 to 80; P = 0.03 by log-rank test). CONCLUSIONS: Among participants with biopsy-proven anal HSIL, the risk of anal cancer was significantly lower with treatment for anal HSIL than with active monitoring.

RESUMEN

PURPOSE: To determine whether treatment of anal high-grade squamous intraepithelial lesions (HSIL), vs active monitoring, is effective in reducing incidence of anal cancer in persons living with HIV, the US National Cancer Institute funded the Phase III ANal Cancer/HSIL Outcomes Research (ANCHOR) clinical trial. As no established patient-reported outcomes (PRO) tool exists for persons with anal HSIL, we sought to estimate the construct validity and responsiveness of the ANCHOR Health-Related Symptom Index (A-HRSI). METHODS: The construct validity phase enrolled ANCHOR participants who were within two weeks of randomization to complete A-HRSI and legacy PRO questionnaires at a single time point. The responsiveness phase enrolled a separate cohort of ANCHOR participants who were not yet randomized to complete A-HRSI at three time points: prior to randomization (T1), 14-70 (T2), and 71-112 (T3) days following randomization. RESULTS: Confirmatory factor analysis techniques established a three-factor model (i.e., physical symptoms, impact on physical functioning, impact on psychological functioning), with moderate evidence of convergent validity and strong evidence of discriminant validity in the construct validity phase (n = 303). We observed a significant moderate effect for changes in A-HRSI impact on physical functioning (standardized response mean = 0.52) and psychological symptoms (standardized response mean = 0.60) from T2 (n = 86) to T3 (n = 92), providing evidence of responsiveness. CONCLUSION: A-HRSI is a brief PRO index that captures health-related symptoms and impacts related to anal HSIL. This instrument may have broad applicability in other contexts assessing individuals with anal HSIL, which may ultimately help improve clinical care and assist providers and patients with medical decision-making.

RESUMEN

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.

RESUMEN

Four cycles of rituximab plus CHOP chemotherapy is as effective as 6 cycles in low-risk diffuse large B-cell lymphoma (DLBCL). Here we report a post-hoc analysis of a prospective clinical trial in patients with HIV-associated DLBCL and high-grade lymphoma treated with 4-6 cycles of EPOCH plus rituximab based a response-adapted treatment strategy. 106 evaluable patients with HIV-associated DLBCL or high-grade CD20-positive non-Hodgkin's lymphoma were randomized to receive rituximab (375 mg/m2) given either concurrently prior to each infusional EPOCH cycle, or sequentially (weekly for 6 weeks) following completion of EPOCH. EPOCH consisted of a 96-hour IV infusion of etoposide, doxorubicin, and vincristine plus oral prednisone followed by IV bolus cyclophosphamide every 21 days for 4 to 6 cycles. Patients received 2 additional cycles of therapy after documentation of a complete response (CR) by computerized tomography after cycles 2 and 4. 64 of 106 evaluable patients (60%, 95% CI 50%, 70%) had a CR in both treatment arms. The 2-year event-free survival (EFS) rates were similar in the 24 patients with CR who received 4 or fewer EPOCH cycles (78%, 95% confidence intervals [55%, 90%]) due to achieving a CR after 2 cycles, compared with those who received 5-6 cycles of EPOCH (85%, 95% CI 70%, 93%) because a CR was first documented after cycle 4. A response-adapted strategy may permit a shorter treatment duration without compromising therapeutic efficacy in patients with HIV-associated lymphoma treated with EPOCH plus rituximab, which merits further evaluation in additional prospective trials. Clinical Trials.gov identifier NCT00049036.

RESUMEN

BACKGROUND: Oral human papillomavirus (HPV) infection has been causally linked to a subset of oropharyngeal cancers in Western populations, and both oropharyngeal cancer and oral HPV infection are increased among HIV-positive individuals. India has high incidences of oral and oropharyngeal cancers, and Indian HIV-positive men who have sex with men (MSM) may be at increased risk of developing oropharyngeal cancers. However, there is little information available on the prevalence of oral HPV in this population. METHODS: We tested 302 HIV-positive Indian MSM for oral HPV infection using L1 HPV DNA PCR with probes specific for 29 types and a mixture of 10 additional types. CD4+ level and plasma HIV viral load (VL) were measured. Participants completed an interviewer-administered questionnaire including a sexual history. RESULTS: The prevalence of oral HPV was 23.7% (95% CI: 19-29%) and 2.4% of participants had oncogenic HPV types. No participants had oral HPV type 16 (HPV-16) and the prevalence of other anogenital HPV types was low. Participants with higher CD4+ levels had reduced odds of having any oral HPV infection (OR: 3.1 [1.4-6.9]) in multivariable analyses. CONCLUSIONS: This is the first report of oral HPV among Indian HIV-positive MSM. Our results show a high prevalence of oral HPV infection consistent with studies from Western populations. However, oncogenic anogenital HPV types were relatively uncommon in our study population. It is unknown what the impact of this distribution of oral HPV will be on oropharyngeal cancers. HIV-positive MSM in India should be monitored closely for oral and oropharyngeal pre-cancer and cancer.

RESUMEN

Gonorrhea remains a major public health challenge, and current recommendations for gonorrhea treatment are threatened by evolving antimicrobial resistance and a diminished pipeline for new antibiotics. Evaluations of potential new treatments for gonorrhea currently make limited use of new understanding of the pharmacokinetic and pharmacodynamic contributors to effective therapy, the prevention of antimicrobial resistance, and newer designs for clinical trials. They are hampered by the requirement to utilize combination ceftriaxone/azithromycin therapy as the comparator regimen in noninferiority trials designed to seek an indication for gonorrhea therapy. Evolving gonococcal epidemiology and clinical trial design constraints hinder the enrollment of those populations at the greatest risk for gonorrhea (adolescents, women, and persons infected with antibiotic-resistant Neisseria gonorrhoeae). This article summarizes a recent meeting on the evaluation process for antimicrobials for urogenital gonorrhea treatment and encourages the consideration of new designs for the evaluation of gonorrhea therapy.

RESUMEN

BACKGROUND: Anal high-grade squamous intraepithelial lesions (HSILs) ablation may reduce the incidence of invasive cancer, but few data exist on treatment efficacy and natural regression without treatment. METHODS: An open-label, randomized, multisite clinical trial of human immunodeficiency virus (HIV)-infected adults aged ≥27 years with 1-3 biopsy-proven anal HSILs (index HSILs) without prior history of HSIL treatment with infrared coagulation (IRC). Participants were randomized 1:1 to HSIL ablation with IRC (treatment) or no treatment (active monitoring [AM]). Participants were followed every 3 months with high-resolution anoscopy. Treatment participants underwent anal biopsies of suspected new or recurrent HSILs. The AM participants underwent biopsies only at month 12. The primary end point was complete clearance of index HSIL at month 12. RESULTS: We randomized 120 participants. Complete index HSIL clearance occurred more frequently in the treatment group than in the AM (62% vs 30%; risk difference, 32%; 95% confidence interval [CI], 13%-48%; P < .001). Complete or partial clearance (clearance of ≥1 index HSIL) occurred more commonly in the treatment group (82% vs 47%; risk difference, 35%; 95% CI, 16%-50%; P < .001). Having a single index lesion, compared with having 2-3 lesions, was significantly associated with complete clearance (relative risk, 1.96; 95% CI, 1.22-3.10). The most common adverse events related to treatment were mild or moderate anal pain and bleeding. No serious adverse events were deemed related to treatment or study participation. CONCLUSION: IRC ablation of anal HSILs results in more clearance of HSILs than observation alone.

RESUMEN

BACKGROUND: In patients with heart failure (HF), high dietary sodium intake is common and associated with HF symptoms, poor health-related quality of life (HRQOL), and high hospitalization rates. PURPOSE: The aims of this study were to examine the feasibility of a tailored dietary intervention with a practical tool (MyFitnessPal) and to obtain preliminary data about the effects on sodium intake, factors affecting sodium intake (knowledge, skills, experiences, confidence, perceived benefits and barriers, and depressive symptoms), HF symptoms, and HRQOL. METHODS: A 6-session intervention was delivered to 11 participants. Paired t tests were used to compare the baseline outcomes with those at 3 months. RESULTS: Participants completed 98% of intervention sessions, and 91% used MyFitnessPal. Sodium intake was reduced, and factors affecting sodium intake, symptoms, and HRQOL were improved (all P < .05). CONCLUSION: The intervention was feasible and warrants further research to test the effects of the intervention on the outcomes using larger, heterogeneous samples.

RESUMEN

Background: Mycoplasma genitalium can result in pelvic inflammatory disease and adverse pregnancy outcomes. We analyzed data collected from a prospective study of asymptomatic bacterial vaginosis (BV) to determine the natural history of M. genitalium. Methods: Women aged 15-25 years, with asymptomatic BV and ≥2 risk factors for sexually transmitted infection were recruited from 10 sites throughout the United States. Vaginal swab samples were collected at enrollment and through home-based testing every 2 months over 12 months. M. genitalium nucleic acid amplification testing was performed for M. genitalium using transcription-mediated assays (Hologic). The prevalence, incidence, and persistence of M. genitalium, defined as all positive specimens during follow-up, were estimated with 95% confidence intervals (CIs). Adjusted odds ratios (AOR) were calculated using logistic and Poisson regression to evaluate participant characteristics associated with M. genitalium infection. Results: Among 1139 women, 233 were M. genitalium positive, for a prevalence of 20.5% (95% CI, 18.2%-22.9%); 42 of 204 had persistent M. genitalium (20.6%). Among 801 M. genitalium-negative women at baseline, the M. genitalium incidence was 36.6 per 100 person-years (95% CI, 32.4-41.3). Black race (AOR, 1.92; 95% CI, 1.09-3.38), age ≤21 years (1.40; 1.03-1.91), and prior pregnancy (1.36; 1.00-1.85) were associated with prevalent M. genitalium; only black race was associated with incident M. genitalium (P = .03). Conclusions: We identified high rates of prevalent, incident, and persistent M. genitalium infections among young, high-risk women with asymptomatic BV, supporting the need for clinical trials to evaluate the impact of M. genitalium screening on female reproductive health outcomes.

RESUMEN

BACKGROUND: Urogenital Chlamydia trachomatis infection remains prevalent and causes substantial reproductive morbidity. Recent studies have raised concern about the efficacy of azithromycin for the treatment of chlamydia infection. METHODS: We conducted a randomized trial comparing oral azithromycin with doxycycline for the treatment of urogenital chlamydia infection among adolescents in youth correctional facilities, to evaluate the noninferiority of azithromycin (1 g in one dose) to doxycycline (100 mg twice daily for 7 days). The treatment was directly observed. The primary end point was treatment failure at 28 days after treatment initiation, with treatment failure determined on the basis of nucleic acid amplification testing, sexual history, and outer membrane protein A (OmpA) genotyping of C. trachomatis strains. RESULTS: Among the 567 participants enrolled, 284 were randomly assigned to receive azithromycin, and 283 were randomly assigned to receive doxycycline. A total of 155 participants in each treatment group (65% male) made up the per-protocol population. There were no treatment failures in the doxycycline group. In the azithromycin group, treatment failure occurred in 5 participants (3.2%; 95% confidence interval, 0.4 to 7.4%). The observed difference in failure rates between the treatment groups was 3.2 percentage points, with an upper boundary of the 90% confidence interval of 5.9 percentage points, which exceeded the prespecified absolute 5-percentage-point cutoff for establishing the noninferiority of azithromycin. CONCLUSIONS: In the context of a closed population receiving directly observed treatment for urogenital chlamydia infection, the efficacy of azithromycin was 97%, and the efficacy of doxycycline was 100%. The noninferiority of azithromycin was not established in this setting. (Funded by the National Institute of Allergy and Infectious Diseases; ClinicalTrials.gov number, NCT00980148.).

RESUMEN

BACKGROUND: Clostridium difficile infection (CDI) is the most common hospital-acquired infection. Unfortunately, genes that identify CDI-susceptible patients have not been well described. We performed a genome-wide association study (GWAS) to determine genetic variants associated with the development of CDI. METHODS: A cohort study of Caucasian patients undergoing autologous stem cell transplantation for multiple myeloma was performed. Patients were genotyped using Illumina® Whole Genome Genotyping Infinium chemistry. We then compared CDI-positive to CDI-negative patients using logistic regression for baseline clinical factors and false discovery rate (FDR) for genetic factors [single nucleotide polymorphisms (SNPs)]. SNPs associated with CDI at FDR of p < 0.01 were then incorporated into a logistic regression model combining clinical and genetic factors. RESULTS: Of the 646 patients analyzed (59.7% male), 57 patients were tested CDI positive (cases) and were compared to 589 patients who were tested negative (controls). Hemoglobin, albumin, and hematocrit were lower for cases (p < 0.05). Eight SNPs on five genes (FLJ16171, GORASP2, RLBP1L1, ASPH, ATP7B) were associated with CDI at FDR p < 0.01. In the combined clinical and genetic model, low albumin and three genes RLBP1L1, ASPH, and ATP7B were associated with CDI. CONCLUSION: Low serum albumin and genes RLBP1L1 and ASPH located on chromosome 8 and ATP7B on chromosome 13 were associated with CDI. Of particular interest is ATP7B given its copper modulatory role and the sporicidal properties of copper against Clostridium difficile.

RESUMEN

Chlamydia trachomatis elementary body enzyme-linked immunosorbent assay (ELISA) was used to investigate serum anti-CT immunoglobulin G1 (IgG1; long-lived response) and immunoglobulin G3 (IgG3; short-lived response indicating more recent infection) from treatment (enrollment) and 6-month follow-up visits in 77 women previously classified as having spontaneous resolution of chlamydia. Of these women, 71.4% were IgG1+IgG3+, consistent with more recent chlamydia resolution. 15.6% were IgG3- at both visits, suggesting absence of recent chlamydia. Using elementary body ELISA, we demonstrated approximately 1 in 6 women classified as having spontaneous resolution of chlamydia might have been exposed to C. trachomatis but not infected. Further, we classified their possible infection stage.

RESUMEN

BACKGROUND: We hypothesized that disconcerting lymphedema rates in both sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND) may be because of unrecognized vunerable variations in arm lymphatic drainage within the axilla. Axillary reverse mapping (ARM) facilitates identification and avoidance of arm lymphatics within the axilla and its use may reduce lymphedema. METHODS: This institutional review board-approved study from June 2007 to December 2013 involved patients undergoing SLNB with or without ALND, or ALND alone. Technetium is injected subareolarly for localization of the breast SLN and isosulfan blue dye (5 mL) is injected in the ipsilateral upper arm for localization of nonbreast lymphatics. Data were collected on identification and preservation of arm lymphatics, crossover rates, blue node metastases, axillary recurrence, and lymphedema as measured by volume displacement. RESULTS: A total of 654 patients prospectively underwent 685 ARM procedures with a SLNB and/or ALND. Objective lymphedema rates for SLNB and ALND were 0.8% and 6.5% respectively, with 26-month median follow up. Blue lymphatics were identified in 29.2% (138/472) of SLNB and 71.8% (153/213) of ALND. Crossover was seen in 3.8% (18/472) of SLNB and 5.6% (12/213) of ALND. Blue node metastases rate was 4.5% (2/44). Axillary recurrence rate was 0.2% and 1.4% for SLNB and ALND, respectively. CONCLUSIONS: ARM allows frequent identification of arm lymphatics in the axilla, which would have been transected during routine surgery. Rates of metastases in noncrossover nodes and axillary recurrences are low. Lymphedema rates are dramatically reduced using ARM when compared with accepted standards.

RESUMEN

The toxicity of dose-intensive regimens used for Burkitt lymphoma prompted modification of cyclophosphamide, vincristine, doxorubicin, high-dose methotrexate/ifosfamide, etoposide, and high-dose cytarabine (CODOX-M/IVAC) for HIV-positive patients. We added rituximab, reduced and/or rescheduled cyclophosphamide and methotrexate, capped vincristine, and used combination intrathecal chemotherapy. Antibiotic prophylaxis and growth factor support were required; highly active antiretroviral therapy (HAART) was discretionary. Thirteen AIDS Malignancy Consortium centers enrolled 34 patients from 2007 to 2010. Median age was 42 years (range, 19-55 years), 32 of 34 patients were high risk, 74% had stage III to IV BL and CD4 count of 195 cells per µL (range, 0-721 cells per µL), and 5 patients (15%) had CD4 <100 cells per µL. Twenty-six patients were receiving HAART; viral load was <100 copies per mL in 12 patients. Twenty-seven patients had at least one grade 3 to 5 toxicity, including 20 hematologic, 14 infectious, and 6 metabolic. None had grade 3 to 4 mucositis. Five patients did not complete treatments because of adverse events. Eleven patients died, including 1 treatment-related and 8 disease-related deaths. The 1-year progression-free survival was 69% (95% confidence interval [CI], 51%-82%) and overall survival was 72% (95% CI, 53%-84%); 2-year overall survival was 69% (95% CI, 50%-82%). Modifications of the CODOX-M/IVAC regimen resulted in a grade 3 to 4 toxicity rate of 79%, which was lower than that in the parent regimen (100%), without grade 3 to 4 mucositis. Despite a 68% protocol completion rate, the 1-year survival rate compares favorably with 2 studies that excluded HIV-positive patients. This trial was registered at http://clinicaltrials.gov as #NCT00392834.

RESUMEN

The U.S. Preventive Services Task Force (USPSTF) recommended screening mammography every 1-2 years for women 40 years and older in 2002, and changed its recommendations in 2009 to no routine screening for women between 40 and 49 years of age; and biennial screening for women between 50 and 74 years of age. This study evaluates the change in mammographic use after the issuance of the revised recommendations. Women who participated in a cross-sectional study of breast cancer risk factors from 2007 to 2013 were asked if they had received a mammogram in the preceding 2 years. All 3442 study participants who enrolled in the study after January 1, 2011 were matched by race, age, and educational level with women enrolled between 2007 and 2010. The proportions of women who stated they had received a mammogram in the past 2 years were compared between the two groups. One fourth of the participants were African American and 39% were 40-49 years of age. Among white women, significant decreases in recent mammogram use from 2007-2010 to 2011-2013 were detected for women 40-49 years of age (-10.3%, p < 0.001) and 50-74 years of age (-8.8%, p < 0.001). Among African-American women, the change in recent mammogram use was not statistically significant for women 40-49 years of age (-2.7%, p = 0.440) or 50-74 years of age (-2.2%, p = 0.398). Following the change in the USPSTF guidelines, mammography use among white women declined; however, no change was observed among African-American women.

RESUMEN

BACKGROUND: Longitudinal studies have consistently found a significant association between bacterial vaginosis (BV) and acquisition of sexually transmitted diseases. However, there are limited prospective data to confirm these findings. METHODS: We conducted a prospective, randomized, open-label trial of home screening and treatment of young women with asymptomatic BV who were also at high risk for sexually transmitted diseases. These women were screened every 2 months for 12 months and randomized to treatment with oral metronidazole 500 mg twice daily for 7 days or observation alone. The primary outcome was the incidence of gonorrhea and/or chlamydia. RESULTS: A total of 1365 subjects were enrolled in the study across 10 sites. Adherence with mailing specimens obtained at home was excellent in both groups (84%-88%). The incidence of gonorrhea and/or chlamydia was 19.1 per 100 person-years (95% confidence interval, 15.1-22.1) for the treatment group and 18.5 per 100 person-years (15.1-22.8) for the observation arm, a difference that was not statistically significant. CONCLUSIONS: Young women were very amenable to home screening for BV, gonorrhea, and chlamydia. Treatment of asymptomatic BV with 1 week of oral metronidazole did not decrease the incidence of gonorrhea and/or chlamydia. CLINICAL TRIALS REGISTRATION: NCT00667368.

RESUMEN

PURPOSE: We examined first (incident) reports of selected adverse experiences associated with medical therapy in men with lower urinary tract symptoms secondary to benign prostatic hyperplasia. MATERIALS AND METHODS: We studied the 6 most common adverse experiences, including nonsexual function related experiences (dizziness, orthostatic hypotension and weakness) and sexual function related experiences (impotence, decreased libido and abnormal ejaculation) reported in the MTOPS (Medical Therapy of Prostatic Symptoms) Study. A total of 3,047 men were randomized to placebo, doxazosin, finasteride or combination therapy and followed for a mean duration of 4.5 years. We compared the incidence rates of adverse experiences at year 1 to the rates thereafter. RESULTS: For each assigned treatment group, the incidence rates were significantly higher for all 6 adverse experiences examined at year 1 compared with the rates thereafter. Men assigned to combination therapy experienced the highest rates at year 1 with rates 3.4-fold to 10.6-fold higher than rates after year 1. The incidence rates for orthostatic hypotension and dizziness were significantly higher in the doxazosin and combination therapy groups compared with the placebo group at year 1. The incidence rates of the 3 examined sexual function related adverse experiences were significantly higher in the finasteride and combination therapy groups than in the placebo group at year 1. CONCLUSIONS: Rates of the first report of sexual function related and other adverse experiences associated with doxazosin, finasteride and combination therapy were greatest during year 1 of treatment. These patterns should be considered by patients and physicians when treatment for lower urinary tract function is initiated with these drugs.

RESUMEN

Limited comparative data exist for the treatment of HIV-associated non-Hodgkin lymphoma. We analyzed pooled individual patient data for 1546 patients from 19 prospective clinical trials to assess treatment-specific factors (type of chemotherapy, rituximab, and concurrent combination antiretroviral [cART] use) and their influence on the outcomes complete response (CR), progression free survival (PFS), and overall survival (OS). In our analysis, rituximab was associated with a higher CR rate (odds ratio [OR] 2.89; P < .001), improved PFS (hazard ratio [HR] 0.50; P < .001), and OS (HR 0.51; P < .0001). Compared with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), initial therapy with more dose-intense regimens resulted in better CR rates (ACVBP [doxorubicin, cyclophosphamide, vindesine, bleomycin and prednisolone]: OR 1.70; P < .04), PFS (ACVBP: HR 0.72; P = .049; "intensive regimens": HR 0.35; P < .001) and OS ("intensive regimens": HR 0.54; P < .001). Infusional etoposide, prednisone, infusional vincristine, infusional doxorubicin, and cyclophosphamide (EPOCH) was associated with significantly better OS in diffuse large B-cell lymphoma (HR 0.33; P = .03). Concurrent use of cART was associated with improved CR rates (OR 1.89; P = .005) and trended toward improved OS (HR 0.78; P = .07). These findings provide supporting evidence for current patterns of care where definitive evidence is unavailable.
