It should be noted that not every increase is indicative of virologic treatment failure and resistance buy 25 mg sominex with amex insomnia 40 weeks pregnant. Slight transient increases in viral load discount sominex 25mg with amex all natural sleep aid 3 ingredients, or blips, are usually of no consequence, as numerous studies in the last few years have shown (see chapter on Goals and Principles of Therapy). The possibility of mixing up samples always has to be considered. Unusually implausi- ble results should be double-checked with the laboratory, and if no cause is found there, they need to be monitored – people make mistakes. Should there be any doubt on an individual result; the lab should be asked to repeat the measurement from the same blood sample. Viral kinetics on ART The introduction of viral load measurement in 1996-1997 fundamentally changed HIV therapy. The breakthrough studies by David Ho and his group showed that HIV infection has significant in vivo dynamics (Ho 1995, Perelson 1996). The changes in viral load on antiretroviral therapy clearly reflect the dynamics of the process of viral production and elimination. The concentration of HIV-1 in plasma is usually reduced by 99% as early as two weeks after the initiation of ART (Perelson 1997). In one large cohort, the viral load in 84% of patients was already below 1000 copies/ml after four weeks. The decrease in viral load follows biphasic kinetics. The higher the viral load at initiation of therapy, the longer it takes to drop below the level of detection. In one study, the range was between 15 days with a baseline viral load of 1000 and 113 days with a baseline of 1 million viral copies/ml (Rizzardi 2000). The following figure shows a typical biphasic decrease in viral load after initial high levels. Monitoring 249 Figure 1: Viral load kinetics during the first months on first-line ART. The grey values derive from 10 patients who achieved a sustained virological suppression, the black values from 3 patients in which resistance mutations occurred during primary therapy (all 3 had NNRTI-based regimens) Numerous studies have focused on whether durable treatment success can be predicted early (Thiebaut 2000, Demeter 2001, Kitchen 2001, Lepri 2001). In a study on 124 patients, a decrease of less than 0. According to another prospective study, it is possible to predict virologic response at 48 weeks even after 7 days (Haubrich 2011). However, this has little clinical relevance, and in our opinion it is pointless to start measurement of viral load only one or two weeks after initiation of therapy. Many studies have evaluated the question whether long-term virological success can be predicted at early phases (Thibaut 2000, Demeter, Kitchen 2011, Lepri 2001). Many of them suggest that changes during the first days after treatment initiation are major correlates of longer-term virological responses. In a study on 124 HIV+ patients initiating a PI-based ART, a decline of less than 0. In another prospec- tive trial, week 1 HIV-RNA change was associated with virologic failure above 50 copies/ml at weeks 24 and 48 (Haubrich 2011). However, such an early measurement is not clinical routine. We recommend meas- uring viral load every four weeks until it has dropped to below detection of 20– 50 copies/ml. Once that is achieved, measurement every three to four months is enough. Eventually, longer intervals are possible (Chaiwarith 2010). In case of rebound, closer monitoring becomes necessary. Within the first 4 weeks of therapy initiation the viral load should be reduced by a factor of 100, after 3-4 months (6 months if viral load was high) it should be below the level of detection.

Klepin1 1Department of Internal Medicine, Section on Hematology and Oncology, Wake Forest School of Medicine, Winston-Salem, NC Characterizing “fitness” in the context of therapeutic decisions for older adults with acute myeloid leukemia (AML) is challenging. Available evidence is strongest in identifying those older adults who are frail at the time of diagnosis by characterizing performance status and comorbidity burden. However, many older adults with adequate performance status and absence of major comorbidity are “vulnerable” and may experience clinical and functional decline when stressed with intensive therapies. More refined assessments are needed to differentiate between fit and vulnerable older adults regardless of chronologic age. Geriatric assessment has been shown to add information to routine oncology assessment and improve risk stratification for older adults with AML. This review highlights available evidence for assessment of “fitness” among older adults diagnosed with AML and discusses future treatment and research implications. It is difficult to compare outcomes between The majority of patients with acute myeloid leukemia (AML) are intensive and less intensive strategies directly across clinical trials age 65 or older, with approximately one-third of patients 75 years in part due to inconsistent eligibility characterizations of fit versus of age at diagnosis. Compared with middle-aged patients, older adults (typically defined as 60 or 65 years) experience Ideally, at the pretreatment evaluation, we want to be able to shortened survival and increased treatment-associated morbidity. Rates of 5-year survival from time of diagnosis after treatment that may mitigate some of the treatment benefit) decline from 39% to 8. This would improve patient-centered treatment decision ence treatment-related death than younger patients, ranging from making, provide specific targets for supportive care interventions, 10% to 30% in many clinical trials.
