The WHI Study of Cognitive Aging (WHISCA) was an ancillary study to the WHI and 206 WHIMS and started 3 years after WHI randomization alli 60mg lowest price. CEE/MPA appeared to have different effects on various cognitive domains in older women after 4 purchase alli 60mg. There were no significant differences between treatment and placebo for other cognitive domains, depressive symptoms, and affect. In the CEE-only study of the WHI, the incidence of probable dementia was not significantly increased at mean follow-up of 5. Rates of mild cognitive impairment 207 were also not significantly increased. Similar to patterns in the CEE/MPA trial, global cognitive function increased for the first 4 years, then decreased, with no significant differences 204 between treatment groups. Subjects with lower baseline scores in cognitive function had the 204 greatest decline in cognitive function (p<0. The largest declines in scores occurred more frequently in CEE than in placebo, and the relative risk of decline of 10 units in the Mini Mental 204 State exam with CEE compared to placebo was 1. Cholecystitis HERS/HERS II reported increased risks for biliary tract surgery among estrogen users 194 with long-term use (mean follow-up of 6. The Nurse’s Hormone therapy Page 55 of 110 Final Report Update 3 Drug Effectiveness Review Project 209 Health Study also reported an increased risk with long-term use (RR=2. Data from this study also suggests that risk for cholecystitis increases with duration of estrogen use. The HERS/HERS II trial reported increased risks for biliary tract surgery among estrogen 194 users early in the study (RR 1. This outcome is supported by results of the Nurse’s Health Study, a large prospective observational study of estrogen users 209 compared to nonusers (RR 1. Ovarian cancer and endometrial cancer The WHI and HERS/HERS II reported no increase in ovarian or endometrial cancer 4, 194 with CEE and MPA. Other studies of unopposed estrogen have indicated increased 210 endometrial cancer for a woman with a uterus. Observational studies of estrogen imply an 211, 212 213 increased risk for ovarian cancer while others do not. Systematic review A recent Cochrane systematic review assessed the effect of long-term hormone therapy on mortality, heart disease, venous thromboembolism, stroke, transient ischemic attacks, breast cancer, colorectal cancer, ovarian cancer, endometrial cancer, gallbladder disease, cognitive 214 function, dementia, fractures, and quality of life. Fifteen randomized controlled trials were included, but the WHI and HERS, the largest trials, contributed most of the data. This review concluded that combined continuous hormone therapy significantly increased the risk of both venous thromboembolism and coronary events after one year, stroke after 3 years, breast cancer after 5 years, and gallbladder disease. In women over age 65, the incidence of dementia was also increased. In younger women (age 50 to 59 years) taking either combined regimens or estrogen-only hormone therapy, there was an increased risk of venous thromboembolism, but the absolute risk was low. Are there subgroups of patients for which one medication or preparation is more effective or associated with fewer adverse effects? Age groups Trials of estrogen and menopausal symptoms were usually conducted among women ranging in age from 40 to 60 years old with the mean age in the early 50’s. Data was not stratified by age and direct within-study comparisons cannot be made. Generally, women with the most symptoms had the most benefit. Trials of estrogen and bone density and fractures were conducted predominantly in older women in order to detect significant treatment effects because the prevalence of low bone density and fractures is higher among older women. The most comprehensive trials of adverse effects (WHI and HERS/HERS II) enrolled older women with mean ages of 63 and 67 at baseline respectively. Data were not stratified by 149 age in HERS/HERS II. In the WHI, there was no evidence that the effect of CEE in reducing fracture risk differed by age or time since menopause. It is not clear how well the findings of these trials relate to younger women using estrogen for short-term relief of symptoms. Younger post-menopausal women (50-54 years of age) who reported moderate-to-severe vasomotor 85 symptoms at baseline were examined in the WHI CEE/MPA study and there was a positive Hormone therapy Page 56 of 110 Final Report Update 3 Drug Effectiveness Review Project effect on sleep disturbance, but no effect on other HRQL measures, despite significant improvement in vasomotor symptoms. These data were consistent with results in older women For Update #3, several studies examined older women and results were similar to studies among younger women. A study of oral estradiol compared to placebo in women over 70 years with an intact uterus did not report significant changes in a “SF-36 score” or in cognitive 26 function. In a study of community-dwelling women 65 years of age and older, Greenspan and 31 colleagues reported no significant difference between treatment with CEE 0. The ULTRA study examined the use of low-dose transdermal estradiol in women 60 to 80 years and found that active treatment did not improve menopausal symptoms, urinary incontinence, or 30, 39, 78 cognitive function at 2 years.

After a follow-up of 3 years purchase alli 60mg line, patients in the low-hematocrit group cheap alli 60mg mastercard, compared with 10. Therefore, the CYTO PV study reduced the risk of the combined primary end point of nonfatal strongly supports control of the hematocrit to at least 0. The use of low-dose aspirin also reduced the 24,25 reduction in thrombosis. There is no evidence to support a risk of the second combined end point to a statistically signiﬁcant targeting the hematocrit 0. The incidence of major bleeding episodes was not related but unanswered dilemma that arises in clinical practice is signiﬁcantly increased in the low-dose aspirin group (relative risk, whether to control the hematocrit of a patient with a diagnosis of ET 1. Interestingly, neither who has the JAK2V617F mutation and whose hematocrit is above overall mortality nor cardiovascular mortality was signiﬁcantly 0. Masked PV should reduced; the trial was probably not adequately powered to address 13 certainly be excluded in these patients. In ET, the use of aspirin has never been addressed in distinction would include use of RBC mass, but because this test is a randomized controlled trial. Some studies, such as PT-1, included not widely available, other factors need to be considered. Such aspirin for all high-risk ET patients, whereas other more recent 15,16 additional factors would include: careful review of BM histology, studies, such as ANAHYDRET, did not. This reﬂects a di- replenishment of iron stores, review of erythropoietin level, and chotomy of opinion in the ﬁeld. These include concerns that testing for endogenous erythroid colonies; sometimes, careful bleeding is a particular risk for patients with very high platelet observation until more obvious signs appear has to sufﬁce. Regarding treatment targets, the European LeukemiaNet used a standard consensus approach to produce criteria for response; these For “low-risk” ET, a retrospective analysis from a group of Spanish criteria are designed primarily for clinical trials and also include investigators suggests variable beneﬁts for low-dose aspirin. Interna- treated with antiplatelet drugs (mainly aspirin) as monotherapy tional practice varies widely, as demonstrated in the ongoing (n 198) or followed with careful observation (n 102). Fol- EXELS study with a recently published analysis of treatment low-up was 802 and 848 person-years for antiplatelet therapy and patterns for high-risk ET across Europe,27 and there are many strong observation, respectively. Rates of thrombotic events were not opinions regarding whether HU or IFN should be the treatment of different at 21. IFN and HU form a mainstay of therapy and there is an therapy and observation, respectively (P.

Pioneering studies with IFN were let medication showed an increased risk of venous thrombosis reported by Silver in 1988. Major bleeding was observed in patients with platelet when started at low doses. This targeting of the JAK2V617F-mutated clone by this agent. In the remaining low-risk tion of IFN from AOP pharma is also of interest in this context, with ET patients, aspirin does not appear to be effective for primary provisional results approximately equivalent to that for other prophylaxis of thrombosis and observation may be an adequate formulations of IFN.

Two such trials are currently ments at weeks 24 and 144, respectively. Clinically meaningful ongoing internationally: MPD RC112, a phase 3 randomized study improvements in pruritus, night sweats, and bone pain were of HU versus Pegasys in newly diagnosed high-risk ET and PV, and observed within 4 weeks of the initiation of therapy and were PROUD-PV, a phase 3 study with AOP IFN in PV.

Three important Impact of JAK inhibitors and other novel therapies safety concerns have arisen with regard to JAK inhibition: a There are data supporting the ability of some JAK inhibitors to “withdrawal syndrome,” neurological toxicity, and risk of infec- control myeloproliferation in patients with PV and ET. An early report suggested a risk of severe inﬂammatory beyond this, aspects that are uncertain include whether they prevent syndrome after ruxolitinib withdrawal and that these patients had a thrombosis and if they affect the probability of accelerated-phase 37 poor outcome.
