THE NATIONAL INSTITUTES OF HEALTH CHRONIC PROSTATITIS SYMPTOM INDEX: DEVELOPMENT AND VALIDATION OF A NEW OUTCOME MEASURE

AbstractPurpose: Chronic abacterial prostatitis is a syndrome characterized by pelvic pain and voiding symptoms, which is poorly defined, poorly understood, poorly treated and bothersome. Research and clinical efforts to help men with this syndrome have been hampered by the absence of a widely accepted, reliable and valid instrument to measure symptoms and quality of life impact. We developed a psychometrically valid index of symptoms and quality of life impact for men with chronic prostatitis.Materials and Methods: We conducted a structured literature review of previous work to provide a foundation for the new instrument. We then conducted a series of focus groups comprising chronic prostatitis patients at 4 centers in North America, in which we identified the most important symptoms and effects of the condition. The results were used to create an initial draft of 55 questions that were used for formal cognitive testing on chronic prostatitis patients at the same centers. After expert panel review formal...

The interstitial cystitis symptom index and problem index

OBJECTIVES To develop 2 brief self-administered indices for measuring lower urinary tract symptoms and their impact in patients with interstitial cystitis (IC). METHODS An initial set of questions was developed and evaluated in focus groups. The index was revised, shortened, and validated with patients diagnosed in 3 large urologic practices with experience in interstitial cystitis (N = 45). Controls were recruited from a group of healthy volunteers in a gynecology clinic (N = 67). Internal consistency, construct validity, and test-retest reliability were evaluated. RESULTS The IC symptom index and the IC problem index measure urinary and pain symptoms and assesses how problematic symptoms are for patients with interstitial cystitis. Psychometric performance of both instruments is good, with the symptom index demonstrating excellent ability to discriminate characteristics between patients and controls. CONCLUSION Both indices should be useful in the evaluation and management of patients with IC and should be particularly useful in clinical trials of new therapies for this condition, where reliable, validated, and reproducible outcome measures are critically important.

A brief male sexual function inventory for urology

OBJECTIVES To develop a brief questionnaire to measure male sexual function. METHODS An initial set of questions was refined and reduced through cognitive testing and two serial validation studies. In each study, men were recruited from a sexual dysfunction clinic and a general medicine practice to complete the instrument. Test-retest reliabilities, internal consistencies, and construct validities were examined. RESULTS The final instrument covers sexual drive (two items), erection (three items), ejaculation (two items), perceptions of problems in each area (three items), and overall satisfaction (one item). Psychometric performance was generally very satisfactory, although self-assessments of ejaculate volume are problematic. Translations have been developed and pilot tested in a number of languages. CONCLUSIONS The Brief Sexual Function Inventory may be useful for measuring male sexual function in practice and research.

Outcomes of Localized Prostate Cancer Following Conservative Management

CONTEXT Most newly diagnosed prostate cancers are clinically localized, and major treatment options include surgery, radiation, or conservative management. Although conservative management can be a reasonable choice, there is little contemporary prostate-specific antigen (PSA)-era data on outcomes with this approach. OBJECTIVE To evaluate the outcomes of clinically localized prostate cancer managed without initial attempted curative therapy in the PSA era. DESIGN, SETTING, AND PARTICIPANTS A population-based cohort study of men aged 65 years or older when they were diagnosed (1992-2002) with stage T1 or T2 prostate cancer and whose cases were managed without surgery or radiation for 6 months after diagnosis. Living in areas covered by the Surveillance, Epidemiology, and End Results (SEER) program, the men were followed up for a median of 8.3 years (through December 31, 2007). Competing risk analyses were performed to assess outcomes. MAIN OUTCOME MEASURES Ten-year overall survival, cancer-specific survival, and major cancer related interventions. RESULTS Among men who were a median age of 78 years at cancer diagnosis, 10-year prostate cancer-specific mortality was 8.3% (95% confidence interval [CI], 4.2%-12.8%) for men with well-differentiated tumors; 9.1% (95% CI, 8.3%-10.1%) for those with moderately differentiated tumors, and 25.6% (95% CI, 23.7%-28.3%) for those with poorly differentiated tumors. The corresponding 10-year risks of dying of competing causes were 59.8% (95% CI, 53.2%-67.8%), 57.2% (95% CI, 52.6%-63.9%), and 56.5% (95% CI, 53.6%-58.8%), respectively. Ten-year disease-specific mortality for men aged 66 to 74 years diagnosed with moderately differentiated disease was 60% to 74% lower than earlier studies: 6% (95% CI, 4%-8%) in the contemporary PSA era (1992-2002) compared with results of previous studies (15%-23%) in earlier eras (1949-1992). Improved survival was also observed in poorly differentiated disease. The use of chemotherapy (1.6%) or major interventions for spinal cord compression (0.9%) was uncommon. CONCLUSIONS Results following conservative management of clinically localized prostate cancer diagnosed from 1992 through 2002 are better than outcomes among patients diagnosed in the 1970s and 1980s. This may be due, in part, to additional lead time, overdiagnosis related to PSA testing, grade migration, or advances in medical care.

Early Parenteral Nutrition in Critically Ill Patients With Short-term Relative Contraindications to Early Enteral Nutrition: A Randomized Controlled Trial

IMPORTANCE Systematic reviews suggest adult patients in intensive care units (ICUs) with relative contraindications to early enteral nutrition (EN) may benefit from parenteral nutrition (PN) provided within 24 hours of ICU admission. OBJECTIVE To determine whether providing early PN to critically ill adults with relative contraindications to early EN alters outcomes. DESIGN, SETTING, AND PARTICIPANTS Multicenter, randomized, single-blind clinical trial conducted between October 2006 and June 2011 in ICUs of 31 community and tertiary hospitals in Australia and New Zealand. Participants were critically ill adults with relative contraindications to early EN who were expected to remain in the ICU longer than 2 days. INTERVENTIONS Random allocation to pragmatic standard care or early PN. MAIN OUTCOMES AND MEASURES Day-60 mortality; quality of life, infections, and body composition. RESULTS A total of 1372 patients were randomized (686 to standard care, 686 to early PN). Of 682 patients receiving standard care, 199 patients (29.2%) initially commenced EN, 186 patients (27.3%) initially commenced PN, and 278 patients (40.8%) remained unfed. Time to EN or PN in patients receiving standard care was 2.8 days (95% CI, 2.3 to 3.4). Patients receiving early PN commenced PN a mean of 44 minutes after enrollment (95% CI, 36 to 55). Day-60 mortality did not differ significantly (22.8% for standard care vs 21.5% for early PN; risk difference, -1.26%; 95% CI, -6.6 to 4.1; P = .60). Early PN patients rated day-60 quality of life (RAND-36 General Health Status) statistically, but not clinically meaningfully, higher (45.5 for standard care vs 49.8 for early PN; mean difference, 4.3; 95% CI, 0.95 to 7.58; P = .01). Early PN patients required fewer days of invasive ventilation (7.73 vs 7.26 days per 10 patient × ICU days, risk difference, -0.47; 95% CI, -0.82 to -0.11; P = .01) and, based on Subjective Global Assessment, experienced less muscle wasting (0.43 vs 0.27 score increase per week; mean difference, -0.16; 95% CI, -0.28 to -0.038; P = .01) and fat loss (0.44 vs 0.31 score increase per week; mean difference, -0.13; 95% CI, -0.25 to -0.01; P = .04). CONCLUSIONS AND RELEVANCE The provision of early PN to critically ill adults with relative contraindications to early EN, compared with standard care, did not result in a difference in day-60 mortality. The early PN strategy resulted in significantly fewer days of invasive ventilation but not significantly shorter ICU or hospital stays.

Ciprofloxacin or Tamsulosin in Men with Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Randomized, Double-Blind Trial

Context Although the cause of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is unknown, physicians sometimes try to treat it with antibiotics or -receptor blockers. Contribution In this multicenter, double-blind factorial trial, 196 men with moderately severe CP/CPPS were randomly assigned to 6 weeks of treatment with ciprofloxacin, tamsulosin, both drugs, or placebo. Neither ciprofloxacin nor tamsulosin substantively reduced symptoms. Implications Ciprofloxacin and tamsulosin were not effective treatments for CP/CPPS. Cautions Patients had long-standing, refractory CP/CPPS and received trial treatments for only 6 weeks. Patients with new diagnoses who are given longer courses of the trial treatments might respond differently. The Editors Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disorder and accounts for approximately 2 million visits to physicians annually in the United States (1). The substantial impact of CP/CPPS includes bothersome lower urinary tract symptoms, sexual dysfunction, reduced quality of life (2-5), and increased health care expenditures (6). The syndrome is diagnosed only on the basis of symptoms, principally pain or discomfort in the pelvic region. No objective measures can help define the disease. Although bacteria can infect the prostate, most men with prostatitis have a negative midstream urine culture, indicating that bacteria may not be the cause of their symptoms (2). Such men are classified as having National Institutes of Health (NIH) category III prostatitis, the most common of the clinically defined prostatitis syndromes (7). It is by no means clear that the disease is characterized by inflammation of the prostate or that the prostate is responsible for symptoms in a substantial proportion of patients. Because of this uncertainty, the term CP/CPPS is used. Chronic prostatitis/chronic pelvic pain syndrome is commonly seen by primary care practitioners, internists, and urologists. In the Olmsted County Study of Urinary Symptoms and Health Status Among Men (8), a population-based study in Olmstead County, Minnesota, the overall prevalence rate of a physician-assigned diagnosis of prostatitis was 9%. Population-based surveys of symptoms have estimated that the prevalence of the syndrome ranges from 9% to 12% among men (9, 10). It is difficult to estimate the proportion of patients with symptoms lasting longer than 3 months whose disorder remains refractory to empirical therapy. These patients are commonly seen by urologists, but whether they represent a minor subpopulation of the overall symptomatic group or make up the majority of patients is unknown. We chose to study these patients because they present with a troubling, long-standing problem and are usually treated with agents of unclear benefit. Even if a relatively large number of men whose symptoms last 3 months or more are cured by standard empirical therapy and the clinical scenario we describe is uncommon, men with refractory symptoms still present a substantial problem to internists and urologists who have little information to guide therapy. Because the cause of CP/CPPS is unknown, affected men receive many empirical therapies. The 2 most common treatments prescribed by physicians are antimicrobial agents and -adrenergic receptor antagonists (2), although there is little objective evidence to support their use (11). Quinolones, such as ciprofloxacin, are commonly used to treat CP/CPPS because of their excellent penetration into the prostate and broad spectrum of coverage for uropathogens and other organisms traditionally believed to be associated with the syndrome (12). Tamsulosin, an -blocker, is an effective treatment for lower urinary tract symptoms in men with benign prostatic hyperplasia, and it has been hypothesized that tamsulosin may improve these symptoms in men with CP/CPPS. This randomized clinical trial was designed to evaluate whether ciprofloxacin or tamsulosin reduces symptoms of long-standing CP/CPPS of at least moderate severity, typical of the 488 men in our Chronic Prostatitis Cohort Study (2). The primary purpose of the trial was to test the most common prescription treatments given to men with CP/CPPS, who are commonly seen in our referral-based urologic practices. Methods Organization The Chronic Prostatitis Collaborative Research Network, a consortium sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), conducted the trial. Urologists and their clinical associates recruited patients at 10 sites in the United States and 1 site in Canada. The NIDDK established an independent data and safety monitoring board to review the progress, safety, and final analysis of the trial. The individual institutional review boards at each of the 10 participating clinical centers approved the study, and all men gave written informed consent. Participants The design of this trial has been described in detail previously (13). Participating urologists recruited both newly referred patients and patients with established CP/CPPS from their referral-based clinical practices at 10 tertiary medical centers in North America. Trial referrals came from primary care providers, internists, and other urologists. The primary diagnostic criterion was pain or discomfort in the pelvic region for at least 3 months in the previous 6 months. Severity of symptoms was assessed by using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) (14, 15). This instrument is a validated questionnaire, completed by the patient, consisting of 4 questions about pain, 3 about voiding symptoms, and 2 about quality of life. The scores in these 3 individual domains (pain, voiding, and quality of life) are combined without weighting to yield the NIH-CPSI total score. Eligible men were required to have at least moderate symptoms, defined as an NIH-CPSI score of at least 15 of 43 possible points, at the time of randomization. We excluded men who had a documented urinary tract infection (midstream urine culture > 100000 colonies/mL) within the past 3 months, a history of active genital herpes within the previous year, a history of genitourinary cancer, inflammatory bowel disease, active urethral stricture, prostate or bladder surgery, or neurologic disease affecting the bladder. We used ligase chain reaction to screen for Chlamydia in urethral urine samples and excluded men whose tests yielded positive results. Previous treatment with antimicrobial agents or -adrenergic receptor blockers, including the study drugs, had to be completed at least 4 weeks before eligibility screening. Additional details of the eligibility criteria are available elsewhere (13). Study Design and Interventions Men were randomly assigned in equal proportions within a 2 2 factorial design to receive placebo; ciprofloxacin alone, 500 mg twice daily; tamsulosin alone, 0.4 mg once daily; or a combination of both drugs (Table 1). Patients were treated for 6 weeks, at which time the primary end point was assessed. Symptoms at 9 and 12 weeks after randomization (6 weeks after completion of treatment) were also assessed to evaluate longer-term treatment response. The 2 baseline screening contacts and the primary end point contact at 6 weeks were clinic visits; interim contacts at 3, 9, and 12 weeks were conducted by telephone. Table 1. Study Design Each patient was randomly assigned by computer. A permuted block randomization schedule with varying block sizes was used, stratified by clinical site. The research pharmacist at each site provided the blinded study drugs in 2 tamper-evident bottles. All clinical investigators, research nurses, and patients were blinded to treatment assignments until all patients had completed follow-up. Outcomes The primary outcome was the change in the NIH-CPSI total score from baseline to 6 weeks. The NIH-CPSI was administered at each of the 2 baseline screening visits, 1 to 3 weeks apart, and every 3 weeks thereafter until 12 weeks. The average of the 2 scores before randomization was used as the baseline score. Evaluation of the responsiveness of the NIH-CPSI indicates that a 4-point change on a scale of 0 to 43 points represents a difference detectable by the patient. Secondary outcomes included changes in the pain, voiding, and quality-of-life subscales of the NIH-CPSI; physical and mental summary scores on the Medical Outcomes Study 12-Item Short-Form Health Survey (16); and a 7-point patient-reported global response assessment. Responders for the global response assessment were defined as men reporting that they were markedly improved or moderately improved at 6 weeks compared with baseline. Men for whom the global response assessment was missing were considered nonresponders and were included in the denominator for the assessment of response rates. Adverse events were monitored throughout the study and graded according to the National Cancer Institute Common Toxicity Criteria (ctep.cancer.gov/reporting/ctc.html). Patients were asked at each contact to report any adverse events that had occurred since the previous contact. The questions were open-ended, and researchers did not ask about any specific categories of adverse events. All events, regardless of whether they were expected reactions to the study drugs, were recorded. Attribution to treatment was also assessed. However, because it was difficult to determine whether certain adverse events, such as pain, were related to treatment or to CP/CPPS, all events were analyzed. Statistical Analysis For each of the 2 primary treatment comparisons, the recruitment goal of 184 patients provided 80% power, at a 2-sided significance level of 5%, to detect a 4-point treatment difference in the NIH-CPSI total score between baseline and 6 weeks. We recognized that although patients could detect this difference, most might not perceive it as a major improvement. However, we did not want to miss even a minor change in

Quality of Life Is Impaired in Men with Chronic Prostatitis: The Chronic Prostatitis Collaborative Research Network

OBJECTIVE: Health-related quality of life (HRQOL) impairment may be a central component of chronic prostatitis for men afflicted with this condition. Our objective was to examine HRQOL, and factors associated with HRQOL, using both general and condition-specific instruments.DESIGN: Chronic Prostatis Cohort (CPC) study.SETTING: Six clinical research centers across the United States and Canada.PARTICIPANTS: Two hundred seventy-eight men with chronic prostatitis.MEASUREMENTS AND MAIN RESULTS: The Short Form 12 (SF-12) Mental Component Summary (MCS) and Physical Component Summary (PCS), and the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) were measures used. CPC subjects’ MCS scores (44.0±9.8) were lower than those observed in the most severe subgroups of patients with congestive heart failure and diabetes mellitus, and PCS scores (46.4±9.5) were worse than those among the general U.S. male population. Decreasing scores were seen in both domains with worsening symptom severity (P<.01). History of psychiatric disease and younger age were strongly associated with worse MCS scores, whereas history of rheumatologic disease was associated with worse PCS scores. Predictors of more severe NIH-CPSI scores included lower educational level and lower income; history of rheumatic disease was associated with higher scores.CONCLUSIONS: Men with chronic prostatitis experience impairment in the mental and physical domains of general HRQOL, as well as condition-specific HRQOL. To optimize the care of men with this condition, clinicians should consider administering HRQOL instruments to their patients to better understand the impact of the condition on patients’ lives.

Correlation of the American urological association symptom index with self-administered versions of the Madsen-Iversen, Boyarsky and Maine medical assessment program symptom indexes

We correlated the American Urological Association (AUA) symptom index with other indexes that have been used to measure symptoms for benign prostatic hyperplasia (BPH) and compared their psychometric properties. A self-administered questionnaire that allowed derivation of AUA, Maine Medical Assessment Program, Madsen-Iversen and Boyarsky symptom scores was completed by 76 men with clinically defined BPH, 59 younger control subjects, and 27 men before and after prostatectomy. The scores from the 4 indexes were strongly correlated (r = 0.77 to 0.93). All 4 indexes had good internal consistency and test-retest reliabilities. All indexes were predictive of patient global ratings of the degree of bother from the urinary condition. The AUA index discriminated BPH patients from controls significantly better than the Maine Medical Assessment Program index, and equivalently to the Madsen-Iversen and Boyarsky indexes (despite having fewer items). All 4 indexes were responsive when BPH patients underwent prostatectomy, although the AUA and Madsen-Iversen indexes were significantly more sensitive.

Consolidation chemoradiotherapy and autologous bone marrow transplantation versus continued chemotherapy for metastatic neuroblastoma: a report of two concurrent Children's Cancer Group studies.

PURPOSE To compare event-free survival (EFS) for patients with stage IV neuroblastoma who were treated with induction chemotherapy followed by additional courses of the same chemotherapy or by intensive chemoradiotherapy and autologous bone marrow transplantation (ABMT). METHODS Two hundred seven children who were diagnosed with stage IV neuroblastoma after 1 year of age were given five to seven courses of induction chemotherapy consisting of cisplatin, etoposide, doxorubicin, and cyclophosphamide (CCC-321-P2). This chemotherapy was continued for 13 total courses for some patients, whereas intensive chemoradiotherapy with ABMT was given to others (CCG-321-P3). The decision to continue chemotherapy versus to consolidate with chemoradiotherapy was not randomized but was made by parents and physicians. Marrow used for ABMT was purged ex vivo and was free of immunocytologically detectable neuroblastoma cells. RESULTS One hundred fifty-nine of 207 patients (77%) remained event-free during induction therapy. Of these, 67 received chemoradiotherapy/ABMT (CCG-321-P3) and 74 continued chemotherapy (CCG-321-P2). Using Cox regression analysis, the relative risk (RR) of an event after chemoradiotherapy/ABMT was estimated to be 58% of that for patients who continued chemotherapy (P = .01). Similarly, Kaplan-Meier analysis estimated EFS at four years for the chemoradiotherapy/ABMT and chemotherapy groups to be 40% and 19% respectively (P = .019). Subgroups appearing to benefit from chemoradiotherapy/ABMT were those with only a partial tumor response to induction chemotherapy (RR = 0.43; P = .008; EFS, 29% v 6%) and those whose tumors had amplification of the N-myc gene (RR = 0.26; P = .112; EFS, 67% v 0%). CONCLUSION Consolidation with intensive, myeloablative chemoradiotherapy followed by purged ABMT may be more effective than continuing chemotherapy for patients with stage IV neuroblastoma.

Alfuzosin and Symptoms of Chronic Prostatitis–Chronic Pelvic Pain Syndrome

BACKGROUND In men with chronic prostatitis-chronic pelvic pain syndrome, treatment with alpha-adrenergic receptor blockers early in the course of the disorder has been reported to be effective in some, but not all, relatively small randomized trials. METHODS We conducted a multicenter, randomized, double-blind, placebo-controlled trial to evaluate the efficacy of alfuzosin, an alpha-adrenergic receptor blocker, in reducing symptoms in men with chronic prostatitis-chronic pelvic pain syndrome. Participation in the study required diagnosis of the condition within the preceding 2 years and no previous treatment with an alpha-adrenergic receptor blocker. Men were randomly assigned to treatment for 12 weeks with either 10 mg of alfuzosin per day or placebo. The primary outcome was a reduction of at least 4 points (from baseline to 12 weeks) in the score on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) (range, 0 to 43; higher scores indicate more severe symptoms). A 4-point decrease is the minimal clinically significant difference in the score. RESULTS A total of 272 eligible participants underwent randomization, and in both study groups, 49.3% of participants had a decrease of at least 4 points in their total NIH-CPSI score (rate difference associated with alfuzosin, 0.1%; 95% confidence interval, -11.2 to 11.0; P=0.99). In addition, a global response assessment showed similar response rates at 12 weeks: 33.6% in the placebo group and 34.8% in the alfuzosin group (P=0.90). The rates of adverse events in the two groups were also similar. CONCLUSIONS Our findings do not support the use of alfuzosin to reduce the symptoms of chronic prostatitis-chronic pelvic pain syndrome in men who have not received prior treatment with an alpha-blocker.
