Children Direct comparisons 52 generic 3 ml bimat with visa, 82-86 Six head-to-head trials included children (Evidence Tables 1 and 2) buy bimat 3ml mastercard. One was poor quality due to a combination of flaws that indicate probable bias generic 3ml bimat overnight delivery, including lack of blinding buy generic bimat 3ml on line, unclear randomization and allocation concealment methods generic 3 ml bimat otc, uncertainty regarding between-groups balance of baseline characteristics, and analyses that excluded a proportion of the original patient Antiemetics Page 29 of 136 Final Report Update 1 Drug Effectiveness Review Project 83 population. A small study comparing intravenous ondansetron with oral disintegrating tablets 85 in children receiving any chemotherapeutic regimen was poor quality for multiple reasons. Randomization resulted in uneven groups, with 56 assigned to intravenous formulation and 39 assigned to oral disintegrating tablet. A smaller proportion of children received chemotherapy with a Hesketh score of 3 to 4 in the intravenous group than the oral disintegrating tablet group (58% compared with 76%). Granisetron compared with ondansetron Two trials comparing granisetron and ondansetron in children found no significant differences in 52, 82 82 efficacy outcomes. Evaluation of efficacy outcomes was based on patient days as the unit of measurement, rather than number of patients, and it is unknown whether the distribution of baseline patient characteristics remained balanced between groups in this type of analysis. Results were stratified by age and the subgroup analysis of 51 (26%) participants under age 18 (mean age not reported) is reported here. Granisetron and ondansetron, respectively, were associated with 0. Between-groups balance of baseline and prognostic factors is unknown because patient-related information was only provided for the group as a whole. Oral ondansetron syrup compared with intravenous ondansetron There were no significant differences in complete response between oral ondansetron syrup compared with intravenous ondansetron (78% compared with 81%) in younger children (mean age 8 years) undergoing moderately to highly emetogenic chemotherapy for various 84 malignancies. Children received loading doses of either oral ondansetron syrup 8 mg or 2 intravenous ondansetron 5 mg/m. Then, all patients then 4 mg of oral ondansetron syrup plus 2- 4 mg of oral dexamethasone every 6 to 8 hours for up to 8 days and 4 mg of oral ondansetron oral solution twice daily for the 2 days that followed cessation of the chemotherapy. Palonosetron compared with ondansetron 2 Intravenous palonosetron 0. Mean age of the children was 11 years and 69% were male. Rates of complete control were 92% for palonosetron and 72% for ondansetron (P=0. There was no significant difference between palonosetron and ondansetron in rate of complete control on days 4 to 7. At baseline there was a significantly greater proportion of undernourished children in the palonosetron group (20% compared with 8%, P=0. Consequently, risk of emetic events in the palonosetron group may have been greater at baseline. Yet despite this imbalance, the palonosetron group had better control of emetic events. If the groups initially were more balanced, the advantage of Antiemetics Page 30 of 136 Final Report Update 1 Drug Effectiveness Review Project palonosetron might have been even greater. However, randomization resulting in uneven groups is indicative of a flawed randomization process, which could bias result in unknown ways. Therefore, we suggest that these results be interpreted with caution. Prevention of nausea and vomiting associated with radiation therapy Adults Direct comparisons No study evaluated the direct comparative efficacy of newer antiemetics in adults undergoing radiation therapy. One small study evaluated both oral granisetron 2 mg (N=18) and oral ondansetron 8 mg (N=15), but only as each compared with a historical control group who did not 87 receive any 5-HT3 antagonists (N=90). Significantly more patients in the granisetron and ondansetron groups had complete control compared to the historical control group (27. Based on our analyses using the Fisher’s exact test (StatsDirect software), direct comparison of complete control rates for granisetron and ondansetron did not find a significant difference between the 5-HT3 antagonists. Placebo-controlled and active-control trials We identified a number of placebo-controlled and active-control trials of dolasetron, granisetron, 2, 88-97 95 and ondansetron (Evidence Tables 7 and 8). Four of the trials of granisetron and 89-91 ondansetron, plus 1 incompletely published trial comparing ondansetron with 98 99 metoclopramide, were previously analyzed in a good-quality systematic review. This review by Tramer et al (1998) made no indirect comparisons and noted that the evidence was limited by variability in underlying risk (wide ranges in placebo response rates), clinical setting, drugs compared, radiation therapy regimen, and endpoints. Conclusions were that (1) ondansetron is consistently efficacious in preventing acute vomiting after total body or upper abdominal 90, 98 irradiation (number needed to treat = 3); (2) limited evidence suggests that ondansetron is 90, 98 efficacious in preventing acute nausea; and (3) there was no difference between granisetron or ondansetron and any placebo or active control in delayed protection from vomiting or 90, 95, 98 nausea. Although our review adds identification of trials that have been published since the final 2, 88, 97 search date for the Tramer review (January 1997), earlier trials that were not in the Tramer 2, 88, 93, 94, 96, 97 review for unknown reasons, and a placebo-controlled trial of the oral disintegrating tablet form of ondansetron, we also were unable to make any indirect comparisons due to the variability described above. Children Head-to-head trials of newer antiemetics for prevention of radiation-associated nausea and vomiting in children were not found. Prevention of postoperative nausea and vomiting Adults Head-to-head trials We included 22 head-to-head trials of 5-HT3 antagonists used to prevent postoperative nausea and vomiting in adults. Trials compared granisetron (10), dolasetron (6), oral aprepitant (2), or Antiemetics Page 31 of 136 Final Report Update 1 Drug Effectiveness Review Project the orally disintegrating tablet formulation of ondansetron (2) with the conventional oral and intravenous forms of ondansetron. There were also 3 trials that involved comparisons of dolasetron and granisetron. We found no head-to-head trials involving palonosetron for prevention of postoperative nausea and vomiting.

Post-Exposure Prophylaxis (PEP) THORE LORENZEN Transmission routes and risks Transmission of HIV may occur if someone comes into contact and incorporates the blood, semen or vaginal fluids of an HIV+ source person. Exposure of intact skin to HIV-contaminated material (e. Besides vertical transmis- sion, HIV transfer is possible if HIV-containing material enters the body by: • needlestick injury or incision by surgical instruments • exposure of damaged skin or mucosal membranes • unprotected sexual intercourse with an infected person • IDU needle or equipment sharing • transfusion of HIV-contaminated blood or blood products Overall, HIV is a low contagious pathogen. The transmission rate ranges between 1:100 and 1:1000. The transmission rate for hepatitis C and B are approximately 10 and 100 times higher, respectively. Factors associated with transmission risk include the amount of source-incorporated virus transmitted and the length of exposure time. Contact with body fluids of a patient with a high viral load probably holds a greater risk than a similar contact with body fluids of a patient on ART with a viral load below level of detection. Additionally, rapid removal of infectious material, e. For percutaneous contact with HIV-containing blood, a transmission rate of 0. Using retrospective data, rates have been calculated more precisely (Table 1). Table 1: Calculations to assess estimated individual transmission risk after HIV exposure* Type of Exposure Relative Risk Deep needle-stick injury or cut 16:1 Fresh blood on the penetrating instrument 5:1 Penetrating needle previously placed in blood vessel 5:1 Source person with high viral load 6:1 Exposition of mucosal membrane 1:10 Exposition of inflammatory damaged skin 1:10 * Source: German-Austrian recommendations for PEP against HIV infection 2013 For information about assumed transmission risk of other types of exposure, please refer to first chapter of this book (Introduction). Simian models show that in mucosal membranes, HIV primarily infects the local immunocompetent cells such as Langerhans cells. These cells and/or their sibling cells migrate to regional lymph nodes; detection of HIV in the blood occurs days later. The process of local infection and migration of the cells to the lymph nodes takes approximately 24–48 hours (Spira 1996, Otten 2000). Theoretically, immediate treatment may avert a systemic infection. Effectiveness and limitations of PEP Early reports on the use of AZT after occupational needle-stick injuries date from 1989. An analysis of retrospective case-control studies shows that even prophylaxis with a single antiretroviral agent after exposure reduces the probability of an infec- tion by approximately 80% (Tokars 1993). In theory, the combination of multiple drugs seems to be even more potent. Furthermore, transmission from patients on ART may lead to transfer of resistant virus strains. The rate of primary resistances in naïve patients varies by region and country, but over the years it has stabilized at approximately 10 to 15% for at least one agent or drug class. How to deal with this issue concerning PEP initiation still remains unclear since resistance testing takes some days or more.
Since HIV could theoretically remain undetected bimat 3ml with amex, sperm washing is currently regarded as a very effective risk reduc- tion order bimat 3ml on-line, although not risk-free order bimat 3 ml on line. Most of the European centers that offer assisted reproduction to HIV-discordant couples are part of the CREATHE network buy generic bimat 3ml line, which aims to optimize treatment and safety of the methods as well as to compile an extensive database bimat 3 ml visa. Compiled data from several centers hint on the safety and reliability of sperm washing (Bujan 2007). Pre-Exposure Prophylaxis (PrEP) Even before the FDA approval of Truvada as the first antiretroviral agent for the prevention of HIV transmission through sexual intercourse, PrEP before periovula- tory unprotected intercourse was an option for serodiscordant couples in some coun- tries. Couples abstain from condom use only during the woman’s fertile days. HIV and Wanting to be a Parent 551 Preconditions are an effectively suppressed viral load, the exclusion of sexually trans- mitted diseases, and unimpaired fertility status of both partners. Data from Switzerland and Germany shows high acceptance in couples. No case of HIV trans- mission has been reported in 53 couples, the pregnancy rate was 75% (Vernazza 2011). A growing number of studies shows the feasibility of this approach, especially in resource-limited settings (Adenji 2013, Whetham 2013). The fertility of HIV-neg- ative men does not seem to be impaired by taking PrEP (Were 2014). Up to now, there is no evidence that PrEP further reduces the already negligible risk of infection when the viral load of the HIV+ partner is effectively suppressed. Nevertheless, some couples prefer this option because it increases their feeling of safety. Female HIV infection For many HIV+ women having a child now is an important part of planning for the future (Fiore 2008, Loutfy 2009). In France 32% of the HIV+ women of reproductive age want to become mothers (Heard 2007). Treatment and care during pregnancy should be carried out according to the pre- vailing national or international guidelines (Fakoya 2008, DAIG 2011, Loutfy 2012). In some European countries reproductive options for women with unimpaired fer- tility include natural conception on the basis of the EKAF Statement as well as self- insemination, while self-insemination is still seen as the safest procedure. Couples who decide for natural conception should undergo screening to exclude STDs. The transmission risk might be further reduced when the intercourse without condoms is limited to the time of ovulation. Women should be advised on the impor- tance of adherence and regular checks of the viral load (Fakoya 2008). If a woman is not taking ART, the viral load is not successfully suppressed, or concerns about the remaining risk are strong, self-insemination may be the method of choice. In some cases, ovarian stimulation may be advisable. This, however, requires highly qualified supervision to avoid multiple gestations. A simple inexpensive way of determining whether the cycles are ovulatory, helpful in women who have regular cycles, is a basal temperature chart beginning about three months before the first self-insemination. At the time of ovulation, couples can either have protected intercourse with a sper- micide-free condom and introduce the ejaculate into the vaginal cavity afterwards, or the ejaculate can be vaginally injected using a syringe or applied with a diaphragm or portio cap. Thus the conception remains within the private sphere of the couple. After 6–12 months of unsuccessful self-insemination, the couple should have further fertility investigations with a view to assisted conception. Should the couple experience problems with self-insemination, intrauterine insemination (IUI) can be considered. HIV-specific and infective diagnostics are recommended. If no pregnancy has occurred over a period of 6–12 months (or earlier, if the couple so wishes) fertility diagnostics should be carried out (Table 1). If there are indicators of reduced fertil- ity in one or both partners, fertility diagnostics might be carried out at an earlier stage in the counselling process. Fertility disorders In some cases, women will only be able to conceive by intercourse without condom or self insemination. Dependent on the fertility status of both partners, IVF and ICSI can be considered as methods of choice. Fertility disorders in HIV+ women seem to have a higher prevalence than in an age- matched negative population (Ohl 2005, Gingelmaier 2010) and might lead to a 552 Women and Children lower success rate of assisted reproduction (Coll 2006) although data show some conflicting results.
In the largest purchase 3ml bimat fast delivery, highest-quality study 3ml bimat with mastercard, there were no significant differences between the formulations on the primary outcome measure (IOWA Conners’ scale) or on 11 secondary 42 measures in a randomized controlled trial of 312 children discount bimat 3 ml on-line. Similarly cheap bimat 3 ml mastercard, a much smaller crossover trial (68 children) that was 7 days long and included behavioral treatment discount bimat 3ml visa, found methylphenidate OROS to have lower scores on the Abbreviated Conners’ Parents scale (total), and on the inattention/overactivity item (out of 16 items), however no differences were found 41 based on assessments made by teachers and counselors. An additional study of 64 children was rated poor quality because it lacked adequate reporting on multiple measures to provide 50 meaningful results. Based on a definition of remission as a score of 0 or 1 (none or just a little) on the 18 items relating to ADHD symptoms only (excluding the items pertaining to oppositional defiant disorder) of the parent assessed SNAP-IV scale, methylphenidate OROS treatment resulted in more patients being classified as in remission at 8 weeks, with a number needed to treat near 4 (see Table 5). Similar results were found using other measures of parental assessment. Because the study was open to patients currently receiving treatment, including immediate-release methylphenidate, and it was unblinded, it is potentially biased against immediate-release methylphenidate. The proportion of patients taking immediate-release methylphenidate, methylphenidate OROS, or who were not taking drug therapy prior to study enrollment was not reported. We undertook an exploratory analysis, pooling the parent ratings of inattention/overactivity subscale items of the IOWA Conners’ scale from these 3 studies, as it was the only item reported across all 3 (see Table 5). While the Wolraich and Pelham studies did not find significant differences in the mean change on this item, the pooled analysis with the Steele study does result in a statistically significant finding, favoring methylphenidate OROS (weighted mean difference, –1. However, we did consider this an exploratory analysis because standard deviations were not provided in the Pelham and Wolraich studies and we made an assumption that the baseline and final scores were moderately correlated 2 (r = 0. A fourth study conducted in Taiwan found methylphenidate OROS superior to immediate-release methylphenidate, assessing the change in Conners’ Teacher Rating Scale Revised Short-Form score by either teacher or parent over 5 time points using a linear mixed model, P<0. The absolute difference in individual scores were not large (Table 4), with the largest difference in teacher ratings being 1. This study had the same potential for bias as the unblinded study by Steele, except that here all patients had previously been taking some form of methylphenidate, but again the proportions taking immediate-release methylphenidate compared with methylphenidate OROS or other formulations prior to enrollment was not reported. In contrast, findings from a retrospective study of 92 children from a “real-life clinical situation” in the United Kingdom suggested that 32% (P<0. The validity and generalizability of these findings were unclear, however, as the study was retrospective in nature, physicians’ use of personal case load to identify patients may have introduced a selection bias, treatment failure was not precisely defined, and it was unclear whether the United Kingdom formulation is comparable to methylphenidate OROS as included in this review. A small 2-week randomized controlled trial (34 children) of immediate-release methylphenidate 43 compared with methylphenidate SR found mixed results. The outcome measures included questionnaires (not validated) completed by a physician, a teacher, and a parent. The teacher questionnaires indicated significant differences in final total score and the “Conduct Problem” scores favored immediate-release methylphenidate. Parent questionnaires indicated a significant difference favoring methylphenidate SR on the “Conduct Problem” item final score, and the physician scores showed no difference. A 3-week study using over-encapsulation for blinding enrolled 327 children, ® comparing immediate-release methylphenidate to Equasym (sold in the United States as ® Metadate CD ). The study analyzed only 87% of patients in the main per-protocol analysis with 47 unclear description of those excluded. The study included a non-inferiority analysis, assuming a difference of ≤ 1. At weeks 1, 2, and 3 immediate-release methylphenidate ® was found equivalent to Equasym. Intent-to-treat analysis as well as subgroup analyses (country, dose, ADHD subtype) was reported in the discussion as supporting these results. Additional analysis examined the effects of the drugs in the morning and afternoon, but a direct comparison was made only to the placebo group as both methylphenidate groups were found similarly superior to placebo at both time points throughout the study. Immediate-release methylphenidate compared with methylphenidate multilayer-release ® (Biphentin ). Two small, fair-quality, crossover studies compared immediate-release ® methylphenidate to methylphenidate multilayer-release (Biphentin , available in Canada, not 53, 54 available in the United States as of September 2011). In the first study, 90 children were randomized to either immediate-release methylphenidate or methylphenidate multilayer-release and had dose titration over 2-3 weeks, with observation by parent, teacher, and investigator over 54 2 weeks. Discontinuations were similar between groups (86% methylphenidate multilayer- release, 89% immediate-release methylphenidate), and mean daily doses were similar between treatments (0. Using the Conners’ scales, “normal” was defined as a final T-score of <65 on each of the 4 subscales. After 5 weeks of treatment, more children taking immediate- release methylphenidate had achieved a normal score on the ADHD Index compared with those taking methylphenidate multilayer-release (90% compared with 79% on the teacher scale and Attention deficit hyperactivity disorder 43 of 200 Final Update 4 Report Drug Effectiveness Review Project 81% compared with 77% on the parent scale). The authors reported that the mean ADHD Index T-scale score was statistically significantly better (lower) with immediate-release methylphenidate based on the teacher scale (mean differences, 3. No other differences were found between treatment groups. The second, smaller study (N=18) reported only single-day measurements after 1 week of 53 immediate-release methylphenidate, methylphenidate multilayer-release, or placebo.
The second systematic review rated included studies as ‘moderate’ quality (range 26 to 82 on a 100-point scale) and found limited evidence 60 on the effectiveness of skeletal muscle relaxants cheap 3ml bimat. One earlier good-quality systematic review evaluated the efficacy of cyclobenzaprine 65 versus placebo for treatment of back pain (Table 1 and Evidence Table 2) buy bimat 3ml fast delivery. This systematic review examined 14 trials of fair overall quality (one abstract and eight trials sponsored by a pharmaceutical company) and found that cyclobenzaprine was associated with better ‘global improvement’ scores at day 14 (odds ratio 4 discount bimat 3 ml with amex. For individual symptoms bimat 3 ml without a prescription, the systematic review found a modest magnitude of improvement (effect size 0 order bimat 3ml online. Information regarding other skeletal muscle relaxants evaluated in included trials (diazepam and methocarbamol) was specifically excluded from analysis in this systematic review. Another good-quality systematic review evaluated the efficacy of 62 cyclobenzaprine versus placebo for treatment of fibromyalgia. It found five trials and assigned an average quality rating score of 4. Although patients on cyclobenzaprine were more likely to report themselves ‘improved’ compared to placebo (odds ratio 3. One fair-quality non-systematic meta-analysis evaluated the comparative efficacy of 70 cyclobenzaprine, diazepam and placebo (Table 1 and Evidence Table 2). This study summarized results of 20 unpublished short-term (2 week) trials performed in the U. It included patients with post-traumatic injury, musculoskeletal strain, radiculopathy, and osteoarthritis. This meta-analysis was rated fair-quality because it did not adequately describe included trials and used an unvalidated method to measure ‘global response’. This study found that the ‘global response’ was equivalent for cyclobenzaprine and diazepam (66% marked or moderate improvement) and significantly better than placebo (40%). Results of head-to-head trials None of the 12 head-to-head trials was rated good-quality; all had at least two important methodological flaws (Evidence Table 5). All trials were rated fair except one trial of cyclobenzaprine versus diazepam that was rated poor because in addition to other flaws, it 126 only reported results for 52 of the 105 enrollees and did not account for the other patients. Of the fair-quality trials, the trial that appeared to be of best quality compared carisoprodol and 129 diazepam. In this trial the authors did not describe allocation concealment techniques, and they used unvalidated methods for assessing outcomes. Carisoprodol was found to be significantly superior to diazepam using unvalidated methods of stiffness, tension, and relief, with average differences for carisoprodol compared to diazepam averaging about 0. No significant differences were seen for pain, activity impairment, or sleep impairment. In other head-to-head trials, a variety of methods were used for measuring outcomes, including various scales for pain (4, 5, or 9 point scales and visual analogue scales), tenderness, and functional status. Most assessment scales were unvalidated, and methods of reporting these outcomes were inconsistent. Functional status was either not measured or assessed using unstandardized and unvalidated methods. Doses of medications investigated were cyclobenzaprine 10 to 20 mg tid; tizanidine 2 to 8 mg tid, chlorzoxazone 500 mg tid to 750 mg qid, carisoprodol 350 mg qid, and diazepam 5 to10 mg tid (Table 4). In these trials, there was no clear evidence that one skeletal muscle relaxant was superior to any other for 123 efficacy. In a trial comparing tizanidine and chlorzoxazone in patients with back pain, there were no significant differences between treatments for muscle pain, muscle tension, tenderness, and activity. More patients reported ‘excellent’ overall results with tizanidine (57%) compared to chlorzoxazone (23%), but similar proportions of patients reported ‘good or excellent’ results (79% vs. A trial of cyclobenzaprine versus methocarbamol in patients with localized muscle spasm found that there were no significant differences in the proportion Skeletal Muscle Relaxants Page 19 of 237 Final Report Update 2 Drug Effectiveness Review Project of patients reporting absent or mild muscle spasm, limitation of motion, or limitation of daily 20 activities. A slightly greater proportion of patients on cyclobenzaprine reported mild or absent local pain compared to methocarbamol (40% vs. In a trial of cyclobenzaprine versus 124 carisoprodol in patients with acute back pain and spasms there were no significant differences for pain, muscle stiffness, activity impairment, sleep impairment, tension, or relief scores compared to baseline. Other head-to-head trials compared an included skeletal muscle relaxant to diazepam. One other 128 trial reported decreased tenderness, decreased limitation of motion and better ‘global evaluation’ for cyclobenzaprine vs. All three of these trials received funding support from a pharmaceutical manufacturer (Merck) and were published in the same book. For most outcomes that favored cyclobenzaprine, the magnitude of difference between treatments was greater at the end of week one than at the end of week two. In one trial comparing chlorzoxazone to diazepam, chlorzoxazone was superior for unvalidated measures of pain, spasm, tenderness, limitation of 51 motion, and interference with activities.

Combination therapy studies comparing rosiglitazone to metformin with both groups 148, 151 receiving other oral agents did not show significant differences between treatment groups. Rosiglitazone was superior to repeglanide (each as monotherapy; no statistics provided). Subjects taking metformin at study entry were randomized to add-on sulfonylurea.

Thiazolidinediones Page 52 of 193 Final Report Update 1 Drug Effectiveness Review Project Key Question 2. For patients with type 2 diabetes do thiazolidinediones differ from each other, from placebo, and from other oral hypoglycemic agents in their effects on macrovascular and microvascular complications, and mortality from diabetes? Summary of the Evidence • Data were not sufficient to determine the comparative effectiveness of pioglitazone and rosiglitazone on microvascular or macrovascular complications of diabetes. Detailed Assessment None of the head-to-head studies identified in the original or updated review examined macro- or microvascular outcomes. Three placebo-controlled or no-treatment comparison studies identified in the original review examined cardiovascular outcomes; all examined patients with known 60, 103, 152 60 macrovascular disease and type 2 diabetes, including the PROACTIVE trial. These 3 trials did not provide sufficient data to determine comparative effectiveness of pioglitazone and rosiglitazone on microvascular or macrovascular complications of diabetes. Both studies provided some evidence of positive effects of these drugs on macrovascular outcomes among patients with preexisting coronary artery disease. Ninety-six percent of patients were taking other glucose-lowering agents, including insulin. The primary endpoint was the composite of all-cause mortality, non-fatal myocardial infarction (including silent myocardial infarction), stroke, acute coronary syndrome, endovascular or surgical intervention in the coronary or leg arteries, and amputation above the ankle. Congestive heart failure was not included in this composite endpoint, although congestive heart failure was examined as an adverse event. When examined individually (as secondary endpoints), none of the components of the primary endpoint changed significantly (P>0. The hazard ratio of the main secondary endpoint (a composite of all-cause mortality, myocardial infarction [excluding silent myocardial infarction], and stroke) was 0. Included patients were aged 50 to 73 years, had a diagnosis of coronary artery disease (>50% stenosis as proven on angiography), had established type 2 diabetes, and had undergone a percutaneous coronary intervention (Evidence Table 9). Forty-one percent took other anti-diabetic medications. At 6-month follow-up the incidence of coronary events was decreased in the rosiglitazone group (between-group P<0. A single-center poor-quality study examined the preventive effects of rosiglitazone on 152 restenosis after coronary stent implantation among 95 persons with type 2 diabetes. In this Thiazolidinediones Page 53 of 193 Final Report Update 1 Drug Effectiveness Review Project open-label, randomized controlled trial, the treatment group was placed on rosiglitazone 8 mg before undergoing catheterization and 4 mg daily thereafter, combined with conventional antidiabetic therapy using a variety of agents (details of concurrent therapy were not provided). The comparison group received conventional therapy only. The rate of restenosis was 18% in the rosiglitazone group and 38% in the control group (between-group P=0. There was also a significant difference in stenosis diameter between groups at 6 months (P=0. The available data provided no information on the comparative effectiveness of pioglitazone and rosiglitazone on macro- and microvascular outcomes when used as monotherapy or when added to or substituted for other oral hypoglycemic agents. Dormandy and 60 colleagues addressed the question of combined therapy as pioglitazone was added to other anti- 103 diabetic therapy in 96% of patients. In the study by Wang and coauthors monotherapy and combined therapy patients were aggregated, so conclusions cannot be drawn about each of these 2 approaches.
These 3 trials did not report outcomes on mortality buy 3 ml bimat with mastercard, end stage renal disease buy cheap bimat 3ml on-line, or quality of life generic bimat 3 ml without a prescription. One trial (N=51) reported percent decline in creatinine clearance for losartan compared 103 with enalapril at 3 months buy 3ml bimat fast delivery. The decline in creatinine clearance was noted to be greater in the enalapril (–15%) compared with the losartan group (percentage not reported) purchase bimat 3ml, but the difference was not statistically significant (P=0. Two trials (N=94) reported changes in creatinine clearance but only as compared with 93, 102 baseline, without inter-group comparisons. One trial (N=54) showed slightly lower diastolic blood pressures among those treated with losartan 93 compared with enalapril (P=0. All 3 studies reported overall withdrawals, but those withdrawals were not consistently broken down by study groups, limiting the ability to make inter-group comparisons. One study reported a subgroup analysis comparing the effect of losartan therapy on participants delineated by baseline proteinuria level (greater than or less than 1. This trial also reported changes in proteinuria between 2 varied doses of losartan; as neither of these subgroups addressed a comparison question between ACE-I and AIIRA, those results will not be discussed here, but details are available in Evidence Table 9. Information on harms was not reported these 3 studies with the exception of the withdrawals related to allergic reactions. Each trail reported 1 withdrawal related to allergic reaction to study medication, but which medication was not specified. Losartan compared with benazepril 88 94, Losartan was compared with benazepril in 3 trials (N=420) conducted in China and Poland. The Reno protection of Optimal Antiproteinuric Doses (ROAD) study by Hou and colleagues is notable as the largest and longest duration trial comparing monotherapy with AIIRA compared with ACE-I with 360 94 participants and 3 years follow-up. The 2 remaining trials followed participants for 5 months 104 and 20 months and had 30 participants each. These trials were produced by the same research DRIs, AIIRAs, and ACE-Is Page 51 of 144 Final Report Drug Effectiveness Review Project group in Poland. Two trials used doses of benazepril 10mg daily and losartan 50mg daily 94, 104 exclusively, while 1 used benazepril 10 mg daily and losartan 50 mg daily as starting doses, but also included escalating doses to maximum of benazepril 40 mg daily and losartan 200 mg 88 94, 104 daily. Two of these 3 trials were homogeneous in terms of participants and enrolled participants with mesangial glomerulonephritis, mesangiocapillary glomerulonephritis, IgA nephropathy, and membranous nephropathy. The 1 remaining trial included a different range of chronic kidney disease, and enrolled participants with glomerulonephritis, polycystic kidney disease, hypertensive renal disease, interstitial renal disease, and those with renal disease of 88 unknown etiology. Two trials included participants with relatively normal renal function (mean 2 94, 104 baseline creatinine clearance greater than 80 ml/min/1. All participants were required to have proteinuria at the time of enrollment; baseline proteinuria was approximately 2 grams per day on average in all 3 studies. A trial (N=360) conducted at a single center in China reported a composite outcome of death, end stage renal disease, and doubling of serum creatinine 88 over 3 years of follow-up. This trial was unique in that half of its participants were randomized to benazepril 10 mg daily compared with losartan 50 mg daily, while the other half were randomized to “maximum” dose groups of benazepril and losartan. In the “maximum” dose groups, doses were titrated to the dose at which each individual achieved optimal antiproteinuric efficacy (as high as benazepril 40 mg daily and losartan 200 mg daily). There was no significant difference for percent reduction in the primary endpoint for losartan compared with benazepril at any dose (P values not reported), but a statistically significant lower percentage of participants reached the primary endpoint in each “maximum” group compared with group on the lower dosage of the same medication. Two trials (N=60) conducted at the University of Gdansk in Poland reported whether or not change in creatinine clearance was significant as compared with baseline (P values not 94, 104 reported). After 5 months, Renke and colleagues found no significant difference in creatinine clearance between groups (P values not reported). In the study by Rutkowski and colleagues, after 14 months no significant change in creatinine clearance was seen between groups or compared with baseline. They noted a numerically greater percent decline in proteinuria for losartan compared with benazepril, but that difference was not statistically significant (P=0. One group (N=360) reported only that change in proteinuria was not statistically significant between losartan and benazepril treatment 88 groups. Raw numbers were not provided for proteinuria changes, so no rough percent change was calculated. One group did not report reduction in proteinuria for monotherapy 94 comparisons. There were no significant differences in blood pressure control between treatment arms in either study. One study did perform a subgroup analysis examining reduction in proteinuria for those participants who started with baseline proteinuria of greater than or less than 2 grams per 104 day. Those with proteinuria of greater than 2 grams per day showed significantly greater reduction in comparison with those with less than 2 grams per day proteinuria at baseline (P=0. Two trials reported overall withdrawals, but did not break down those withdrawals by 94, 104 treatment group. This trial noted a 23% to 25% withdrawal rate in the 2 benazepril groups, compared with a 6% withdrawal rate in the 2 losartan groups. The majority of those withdrawals DRIs, AIIRAs, and ACE-Is Page 52 of 144 Final Report Drug Effectiveness Review Project in the benazepril groups were related to cough; if the withdrawal rate for the benazepril groups is calculated excluding withdrawals for cough, then the withdrawal rate ranges from 4% to 8%.
