A prior Cochrane meta-analysis (dated January 2002) found 21 randomized trials of saw palmetto and concluded that the evidence supported a modest beneficial effect of saw palmetto on 134 both symptoms and flow rates and found few adverse effects associated with its use discount extra super viagra 200mg without a prescription impotence marijuana facts. These trials employed sample sizes of 85 to 225 participants with follow-up times lasting three to 12 months discount 200mg extra super viagra with amex purchase erectile dysfunction drugs. All trials used a dose of 320 mg per day of the extract in single or divided doses order extra super viagra 200mg on line erectile dysfunction milkshake. In addition to the placebo-controlled trials cheap extra super viagra 200 mg without prescription shakeology erectile dysfunction, two trials compared saw palmetto 320 mg/day with 139, 140 tamsulosin 0. Five other trials examined combinations of dietary supplements, in which one of the constituents was saw palmetto (see below). Efficacy and Effectiveness Outcomes Symptoms and Quality of Life © Copyright 2010 American Urological Association Education and Research, Inc. Despite an apparent improvement in symptoms among the participants in each treatment group, within-group comparisons are of little value for assessment of specific pharmacologic efficacy of any supplement, as this response may be due to regression to the mean and a strong placebo effect. In both studies, only small changes in any treatment group were observed over the follow-up periods and there were no statistically significant or clinically meaningful differences in changes between groups. The results were similar in the one trial with tamsulosin-treated controls that reported sexual-functioning outcomes; this study also reported that saw palmetto- allocated participants had fewer ejaculatory disturbances compared to those assigned to the alpha- 139 blocker. None of the trials reported a significant difference in Qmax between saw palmetto and placebo-treated participants, 142, 137 including the one trial that did find a difference in symptoms. The active-controlled studies comparing saw palmetto with tamsulosin also found no significant difference in urinary flow rates at 139, 140 closeout. Safety Outcomes Adverse Events No significant differences in rates of adverse events were found between the two arms of all placebo-controlled trials, though only one study conducted thorough laboratory testing for potential 136 toxicity. Urtica Dioica In addition to saw palmetto, the only other single phytotherapeutic with recently published data is an extract of the stinging nettle plant (Urtica dioica). Prior studies of Urtica have been inconsistent; few trials of a pure Urtica extract exist. In this trial, the Qmax was substantially improved in the Urtica-treated group 146 compared to the placebo group (+8. Postvoid residual volume declined to a greater extent in the active treatment 146 group compared to the placebo group (37 vs. Safety Outcomes Adverse Events No adverse events in either treatment group were reported in this trial and withdrawal rates 146 were similar between the two arms. Most of these products contain saw palmetto in addition to a variety of other dietary supplements. Among the more recently published randomized trials, six studies have reported comparative effects of five different herbal blends: two trials of a combination of saw palmetto 147 148 and Urtica dioica (one placebo-controlled, the other using a tamsulosin comparator), three placebo- 149-151 controlled trials of a product containing saw palmetto and one trial of an Ayurvedic herbal blend of 152 phytotherapies that did not contain saw palmetto. Sample sizes for these trials ranged from 40 to 257 and follow-up times varied from three months to 15 months. Efficacy and Effectiveness Outcomes © Copyright 2010 American Urological Association Education and Research, Inc. The two largest trials of saw palmetto-containing herbal combinations showed 147, 150 significant improvements in the active-treatment arms compared to the placebo arms; the two smaller trials found no significant differences but may have been hindered by insufficient statistical 149, 151 power (the first of these was a mechanistic study and was not intended to be fully powered for symptom outcomes). The same study reported no effect of either the saw palmetto-Urtica blend 148 or the alpha-blocker on indices of sexual or erectile functioning over the course of the trial. Marks et al (2000) reported that participants treated with a saw palmetto blend had a greater reduction in% 149 epithelium and an increase in the percent of atrophic glands in biopsy specimens. Peak urine flow outcomes were not reported for either of the active- comparator trials. Among the four placebo-controlled trials of saw palmetto-containing compounds, three found no significant difference between treatment groups while one reported a small but 151 significant difference between groups. Prostate volume was measured in two placebo-controlled studies of saw palmetto-containing combination products. In both of these trials, there was little change in overall prostate size and no significant differences between groups in observed changes in the prostate volume. The lumen of the prostatic urethra is directly visualized with an endoscope and two needles are inserted from the prostatic lumen laterally into the prostatic adenoma. A double needled is inserted on both the right and left sides (some have likened the appearance to the antennae of a butterfly). Each needle simultaneously emits radiofrequency energy sufficient to heat the prostate to a temperature exceeding that necessary to cause prostatic tissue necrosis in an oval-shaped lesion around the needle tips. Four areas of necrosis result from each round of treatment, which lasts several minutes. Depending on prostatic size and length, multiple dual insertions at different levels along the length of the prostate may be utilized. The concept is to heat the transition zone of the prostate while sparing the urethral mucosa; preserving the mucosa reduce pain and improve patient tolerance. The conclusion now is that the reduction in prostatic volume is less than initially anticipated. Concepts such as prostatic muscle dysfunction, alpha adrenergic nerve dysfunction and other concepts were proposed; however, no clear conclusion has been reached. No significant short-term complications, including need for transfusion, were reported in 155 either arm of these three reports, nor was bleeding reported a fourth randomized trial. The improvement for both arms was sustained at five years but there was a slight deterioration in both 153 154 arms. Short-term complications, including the need for transfusion, are uncommon or nonexistent. Four are larger 156-159 group studies; the others included fewer than 50 patients. These cohort studies are often retrospective and occasionally stated to include consecutive patients. These studies confirm that symptom scores, QoL and Qmax improve in a fashion very similar to that reported in the randomized trials and will not be detailed again here.

As of October 4 buy 200mg extra super viagra mastercard erectile dysfunction pills generic, 2007 generic 200 mg extra super viagra severe erectile dysfunction causes, 233 patients had entered the screening process trusted extra super viagra 200mg erectile dysfunction quiz test, 191 were eligible to begin study treatment buy discount extra super viagra 200mg erectile dysfunction pump rings, 191 had started study treatment, and 59 had completed 2 years of study treatment. As of October 4, 2007, a total of 114 patients had been screened, 80 had consented to enrollment, and 52 had been randomized to treatment. The other observational study is expecting to enroll 285 patients and follow them prospectively for long- term outcomes. One of the studies is a phase I study designed to look at the effect of hydroxyurea on morbidity and aerobic capacity in patients with chronic kidney disease and pulmonary hypertension. Two trials were described as evaluating the use of clotrimazole with hydroxyurea, but these trials were listed as starting in 1997 and 1999, so we are uncertain if these trials are in progress or were never initiated. From an e-mail communication with Bruce Barton, PhD, of the Maryland Medical Research Institute, we are aware of 17 analyses at various stages of development that will be extremely useful contributions to this body of knowledge. These are listed in Appendix C, Evidence Table 30, and include analyses of reproductive outcomes associated with the use of hydroxyurea, analgesia usage, pulmonary hypertension progression in patients on hydroxyurea, and others. However, there are still substantial research needs that relate to the use of hydroxyurea in patients with sickle cell disease. Also, effectiveness trials are needed to assess the use of hydroxyurea in a regular care setting. These could be clustered randomized trials in which some providers are randomized to use hydroxyurea in all patients and other are randomized to usual care, including the use of hydroxyurea when clinically indicated, or effectiveness studies in which one group of providers is actively encouraged to consider hydroxyurea when appropriate and another clinic is not targeted for education. Studies are needed in which patients are treated for a longer time, as are studies in which patients are followed for a longer time, even if the treatment is discontinued. This design is most relevant to assessing outcomes with a long latency period, such as leukemia and secondary malignancies, including skin cancers. Certainly, it may not be feasible to run randomized trials for many years, so a well-designed prospective study may be the optimal design. A registry of users of hydroxyurea could also be considered if the data collection and followup can be sufficiently rigorous. Effectiveness studies of the drug in resource-poor populations would be particularly beneficial. The interactions between hydroxyurea and these underlying diseases, and between hydroxyurea and therapies for these diseases, need to be understood. Further research on the place of hydroxyurea in therapy is indicated, since the existing studies have not defined the optimal time for initiation of the drug or identified the indicators that a patient has failed therapy with hydroxyurea. Other questions remain to be answered: Is there a role for rechallenge with the drug if there was no previous efficacy? What are the best intermediate outcomes that will predict clinical response to the drug? Given that we have concluded that there is evidence to support the efficacy of hydroxyurea, there is clearly a need for further research on the barriers to the use of this drug. These studies should specifically aim to identify barriers at the level of the patient, at the level of the provider, and at a societal level, perhaps with special attention to adult patients. After these barriers are better characterized, interventions to overcome these barriers should be tested, including replication of the one promising study that 75 demonstrated improved receipt of routine care in patients with sickle cell disease. The barriers and intervention that we identified as influencing the use of other treatments in sickle cell disease may provide an appropriate starting point for further study, and comparative effectiveness studies may be appropriate as well, in particular for testing established interventions for improving pain control. Implications this systematic review has important implications for clinicians, policymakers, and researchers. Clinicians should be encouraged by the established efficacy of hydroxyurea in sickle cell anemia. This drug has been demonstrated to have favorable hematological effects that, importantly, have been shown to clearly translate into clinical benefits. These findings affect the care of both children and adults with sickle cell disease. However, clinicians must also be aware of the paucity of long-term safety data, although the scanty evidence that exists is somewhat reassuring. In addition, clinicians must appreciate that there is very little information available regarding many important clinical issues, including the optimal dose for producing the best clinical outcomes, as well as clear indicators for initiating therapy or for discontinuing therapy because of a poor response. The major gaps in our knowledge about hydroxyurea, described in this report, should motivate researchers to search for answers. Also, if this drug is shown to have long-term safety, research needs to be directed at testing interventions to overcome barriers to the use of this drug so that patients have the opportunity to enjoy its benefits. This medication is not being evaluated for comparative effectiveness or comparative safety with reference to established therapies. Although it was beyond the scope of this report to describe the funding challenges in sickle cell disease research, we note a recent article that describes the state of funding for such 186 research. The report noted that even though cystic fibrosis affects fewer than half the number of Americans affected by sickle cell disease, there is a dramatic discrepancy in their funding. The implication is that patients from racial minorities, and often a low-socioeconomic stratum, may not have the organizational strength and resources to command research dollars.
