Thus cheap 50mg imitrex with visa, the current (and realistic) goal of ART in 2015/16 is to prolong the patient’s life and maintain the best possible quality of health and life generic 50mg imitrex free shipping. Patients and physicians most likely have to deal with lifelong treatment. Lifelong, meaning decades, as many epidemiological studies suggest a normal life expectancy for HIV+ patients (Obel 2011, Nakagawa 2012). The goals and principles of lifelong treatment will be discussed in the first part of this. The treatment goal “HIV cure” will be discussed separately in the second part. Success and failure of lifelong treatment Both success and failure of treatment can be evaluated using the same criteria – viro- logic, immunologic or clinical. The first indicator, virologic, is the change in viral load. This is followed, often a little later, by immunologic markers (rise or fall in CD4 T cell count). Clinical outcome usually only becomes apparent much later – first the lab values deteriorate, then the patient; or vice-versa, as lab values get better, the patient generally follows. The clinical success of ART for asymptomatic patients is often not perceived, although the risk of opportunistic infections is reduced to half after only three months on ART (Ledergerber 1999) – the individual may not realize what was avoided by starting therapy. Virological treatment success and failure On ART, viral load declines in at least two phases (see Monitoring). An initial, very rapid decrease in the first few weeks is followed by a longer phase, in which plasma viremia declines slowly. Virological treatment success is usually understood as being the reduction of viral load to below the level of detection (usually 50 copies/ml). This should be reached after 3–4 months; in cases of very high baseline viral load it may take longer. However, a viral load above the level of detection after six months of treatment almost always needs to be evaluated. The same is true if a rebound in viral load is confirmed. The more rapid and greater the decrease in viral load, the longer the therapeutic effect (Kempf 1998, Powderly 1999). In the early INCAS Trial, the relative risk of treatment failure in patients who had reached a viral load below 20 copies/ml was 20 times lower than in those who never reached 400 copies/ml (Raboud 1998). Virologic treatment failure can be recognized quite early. In practice, viral load should be monitored after four weeks on ART. This is useful not only to the patient for reasons of well-being (“less virus, more CD4 cells”). But it is also an important indi- cation for the continued success of treatment. If the viral load is not below 5,000 copies after four weeks of ART, later treatment failure is likely (Maggiolo 2000). If the viral load is not below 500 copies/ml or at least one log below baseline, the like- lihood of having a viral load of 500 copies/ml at week 24 is only 9% (Demeter 2001). In ACTG 5202, a less robust week 4 virologic response was associated with higher risk for subsequent virologic failure (Gant 2013). According to another prospective study, virological response can be predicted even after 7 days (Haubrich 2011). However, viral load testing after such short periods of ART in previously untreated patients is not clinical routine. Goals and principles of therapy 145 The cut-off point of 20 or 50 copies/ml is somewhat arbitrary. It is based on the currently available viral load assays. Whether 60 copies/ml are indeed worse than 30 copies/ml and indicate a lower success of treatment has yet to be proven. In the case of a persistent low level viremia (LLV) between 20 and 50 copies/ml, the risk of virological failure seems not to be increased (Charpentier 2012). There are, however, other studies suggesting an association between the level of viremia and virological failure, even at very low levels (Maggiolo 2012, Pugliuese 2013). Thus, the signifi- cance of LLV is still a matter of a debate. At such low levels, methodological inac- curacies must also be taken into account.
