All these details must be discussed before initiating therapy as ART needs to become one more part of normal daily life 100mg zudena with visa. Adherence Compliance is defined as a patient’s consent and acceptance of therapy buy discount zudena 100mg on-line. In the mid- 90’s a new term, “adherence”, from the English, was adopted. Since then, the more politically correct term – “adherence” is frequently used. This term refers to both physician and patient working together to set up a treatment concept acceptable to both parties and emphasizes that responsibility for failure of the therapy is not auto- matically the patient’s fault. Adherence includes all factors that influence staying on a regimen, in terms of accept- ability, under these three headlines: 1. The success of a treatment is endangered if medication is taken irregularly 2. Clinicians tend to overestimate a patient’s adherence 3. Adherence diminishes with the complexity of the treatment Is the patient able to take the pills on his own? Did he understand that ART is a life- long treatment that should not be stopped when he feels better? Did he realize that there is no need to tolerate severe side effects? What is realistic, given his private and social background? No doubt: adherence is the Achilles’ heel of every antiretroviral therapy. Non-adher- ence is the main, if not the major factor for developing resistance and treatment failure (Turner 2000). Partial viral suppression with insufficient drug levels is an ideal condition under which resistance grows. Taking either more than 90% or less than 69% of the treatment are both associated with a lower risk of resistance (Sethi 2003). Not only drug users, those dependent on alcohol or patients with side effects are considered “risky patients” when it comes to adherence. In several studies, depressed patients, patients living alone and younger patients have been identified as problem groups (Murri 2001, Glass 2006). Positive factors are the physician’s experience, the patient’s confidence in the positive effects of ART, and social support. Race, sex or stage of disease does not seem to be relevant. The individual’s general view of illness and health, accepting modern medicine and fear of side effects are further consid- erations. However, all these factors vary greatly, and in the end, adherence is diffi- cult to predict in individual cases (Lerner 1998). The physician must rely on expe- rience and intuition. The importance of taking drugs regularly has been demonstrated in numerous studies. In one study with 99 patients, in which compliance was evaluated via an electronic monitoring system, the rate of viral treatment failure was only 22% in patients with a compliance level of at least 95% (95% of doses taken). Failure rates of 61% and as much as 80% were measured with a patient’s adherence between 80–94% and <80% (Paterson 2000). However, it must be taken into consideration that this much-cited study is outdated. Newer drugs, such as darunavir, with longer half-lives, higher resistance barriers and better overall pharmacokinetics may forgive a clearly higher non-compliance (Nelson 2010). In the previously mentioned study, clinicians misjudged their patient’s com- pliance in 41% of the cases. Nurses did better – judging incorrectly in only 30% of the cases (Paterson 2000). Adherence tends to be overestimated in other studies as well (Miller 2002). The importance of adherence was also demonstrated in patients with directly observed therapy (DOT) or directly administered ART (DAART), applied in some penal institutions in the US.

The BCR-ABL, in terms of the long-term prospects of survival is only ENESTnd study demonstrated adverse outcomes for patients 10% small. There is a 1% versus 3% risk of death over the subsequent 5 at 3 months whether they received frontline nilotinib or imatinib. These observations be any different for high-risk patients in whom the sole focus is suggest that, although the 3-month MR is a good indicator of the survival? At this stage, we do not have any evidence that molecular long-term probability of achieving a deep MR and the short-term and cytogenetic targets should be any different for high-risk risk of progression, it has limited value as an indicator of high risk patients. This is because 3 months will often be too late to reverse an adverse outcome. Survival and treatment-free remission For patients with a (non-CML-related) life expectancy of more than Risk-adapted therapy 10 years, the achievement of a deep MR will usually be a high Another important consideration when choosing frontline therapy is priority because it brings with it the possibility of a trial of drug the patient’s prognostic score. There are 3 scoring systems that are cessation and treatment-free remission. Assuming that the clinician currently being applied in CML, the Sokal, Hasford, and EUTOS and patient accept treatment-free remission as a long-term goal, how systems, and there is no clear indication that one is superior to the does this change the molecular targets of therapy? Regardless of which scoring system is used, a high score is patients in Australia demonstrated that the key molecular targets associated with a higher risk of progression to AP or BC. Because that were predictive for the achievement of stable undetectable both nilotinib and dasatinib have been shown to reduce the risk of MRD on ongoing imatinib therapy were a BCR-ABL value 10% CML progression, these drugs might be preferred over imatinib in by 3 months and 0. This conclusion is supported by the higher rates of deep There are many other predictive markers that may prove to be better MRs observed at 2 years and beyond with nilotinib or dasatinib in than the current risk scores or, more likely, provide additional the phase 3 trials compared with imatinib (Table 1). However, these predictors are either not widely available, have not been prospectively established as independent Relying on the early MR to identify the high-risk predictors, or both. Current recommendations cannot incorporate these biomarkers, but in the next section we cover the most patient promising candidates. One strategy designed to maximize the use of imatinib and only use more potent TKIs where there is evidence of a high risk of progression is to use frontline imatinib and rely on the MR at 3 Future prospects in optimizing frontline therapy and/or 6 months to identify the high-risk patients and switch them to A better strategy might be to select the optimal TKI on the basis of a more potent TKI. This was the rationale for the TIDEL II study in biological markers of risk or treatment response. Patients who were 10% BCR-ABL at 3 months were high risk of progression or drug resistance could potentially be dose escalated to imatinib 800 mg and, if still 10% at 6 months, identiﬁed at diagnosis and treated aggressively on investigational switched to nilotinib (cohort 1, n 105) or switched at 3 months protocols. To be valuable in this setting, the assay(s) must predict straight to nilotinib if they were 10% (cohort 2, n 105). The with a high degree of accuracy those patients destined to respond ﬁnal analysis is not yet complete, but it is clear that this approach poorly to imatinib. In addition, the assay should ideally describe the Hematology 2013 171 underlying resistance mechanism such that the next TKI or therapeu- GFI-1 tic strategy can be rationally selected.

It therefore remains unclear whether this assay can determination.
