Metzeler et al demonstrated that in ELN favorable-risk Approximately half of younger patients and 90% of older patients patients with CN-AML who have a CEBPAdm and or NPM1mut/FLT3- 36 relapse and these relapses often appear to be associated with clonal ITDneg buy 250 mg divalproex visa, TET2 mutated patients did poorly on all survival end points 500 mg divalproex amex.

Although multivariable analysis strated that the founding clone in the primary AML gains mutations revealed an independent impact of TET2 mutations cheap 250mg divalproex with mastercard, age may be an and evolves into the relapse clone and a subclone of the founding important confounding factor. This is supported by the report from clone survives initial therapy, gains additional mutations, and Gaidzik et al focusing on a large cohort of homogeneously treated 39 35 expands at relapse. In both scenarios, it may be helpful for the younger adults. In that study, TET2 mutations had no prognostic clinician to know the genetic background of the disease at relapse. Younger patients, is limited; in older patients, a conﬁrmatory study of the results adults (age 16-49 years) who relapsed after intensive consolidation from Metzeler et al is needed. DNMT3A has been found to be mutated frequently in AML with Based on these data, the current practice to postpone allo-HSCT in normal karyotype (30%-35%). Marcucci et al years and therefore the results cannot be generalized. In addition, reported on a differential prognostic effect of DNMT3A mutations in clonal evolution may inﬂuence the probability of achieving a second older versus younger patients according to the affected codon; older CR, which has been exemplarily shown by Kro¨nke et al in AML patients with DNMT3A mutations in codon R882 in exon 23 had an with NPM1 mutations.

A new alternative could also be boosting of atazanavir (or darunavir) with cobicis- tat order 500 mg divalproex free shipping.

Replacement of thymidine analogs with other NRTIs The thymidine analogs AZT and d4T cheap divalproex 250mg overnight delivery, which play a leading role in mitochondrial toxicity, is frequently replaced with other nucleoside analogs. In McComsey 2004 and Moyle 2005, only patients with LA were investigated. In particular, the subcutaneous fat of the limbs increases, although at first the improvement is often unrecognizable clinically and can only be detected in DEXA scans (Martin 2004). Histological inves- tigations have shown that the elevated rate of apoptosis in adipocytes normalizes when d4T is replaced (Cherry 2005, McComsey 2005). Based on the available data, it seems advisable to replace d4T with another nucleo- side analog. According to a warning letter by the company BMS of March 2011, d4T should only be used if other antiretroviral substances can not be used and duration of treatment should be as short as possible, and patients should change to a more suitable therapy alternative whenever possible. Unfortunately, it still plays a role in 208 ART resource-limited regions for the time being. A dose reduction may be able to reduce adverse events (McComsey 2008). With regard to AZT, a replacement should be con- sidered when lipoatrophy or anemia becomes manifest. To avoid a hypersensitivity reaction the patient’s HLA status should be known before switching to abacavir (Carr 2002). Switching to tenofovir Studies on ART-naïve patients have shown that the short-term mitochondrial toxi- city of tenofovir is lower than that of d4T or AZT (Gallant 2004+2006). In the 903 Study, lipids improved in patients that were switched from d4T to tenofovir. There was also an increase of the mean limb fat after three years (Madruga 2007). Several studies, some of them randomized trials, point in the same direction. Lipids, lipoatrophy, mitochondrial toxicity and patient satisfaction improve on tenofovir (Milinkovic 2007, DeJesus 2008, Ribera 2008, Fischer 2010, McComsey 2012, Martinez 2012). Recently, a double-blind, placebo-controlled, randomized study showed unexpected results. In ACTG A5206, the addition of tenofovir alone to existing virologically-sup- pressed ART regimens improved lipid parameters compared to placebo (Tungsiripat 2010). However, the mechanism of the lipid-lowering effect warrants further study. In a retrospective study, replacing d4T with tenofovir improved both lipids and liver enzymes (Schewe 2006). There is also one trial showing that switching from ABC+3TC to FTC+TDF in persons with hypercholesterolemia on efavirenz maintains virologi- cal control and significantly improves key lipid parameters (Moyle 2015). It must be noted that also negative effects may arise when switching to tenofovir. Randomized studies in treatment-naïve patients have observed a stronger reduction of bone density on tenofovir, compared to other NRTIs (Martin 2009, Stellbrink 2010). This negative effect is also seen in pretreated patients and there are also studies showing significant decreases in bone density after a switch to tenofovir (McComsey 2011, Haskelberg 2012, Rasmussen 2012). Bone turnover markers do improve when tenofovir is replaced by raltegravir or abacavir (Bloch 2012, Negredo 2015). The potential nephrotoxicity of tenofovir is another point. Switching to tenofovir-containing triple-nuke combinations must be avoided in general, as several studies have shown a high risk for an increase in viral load when switching to this combination (Hoogewerf 2003, Perez-Elias 2005), even after many years on successful ART. The resistance barrier is too low, as the patients example above shows. In practice, changes are often made that go further than PI and d4T/AZT, such as replacement of ddI, simply due to concerns over long-term toxicity. Such switching is based on laboratory studies showing a certain hierarchy with respect to mito- chondrial toxicity. A lot of attention is being drawn to simplification of therapy, in which mono- or nuke-sparing strategies are being used (see below). So far, there is no clear clinical evidence to show that this procedure has any benefit for the patient.
