As the benefits accrue early and a substantial number of re-hospitalizations occur in the first 2 months of heart failure discharge, in-hospital initiation of beta-blocker therapy is expected to result in even more significant reductions in total medical costs as well as lives saved. Children, from page 1 Pharmacokinetics Due to evolving organ function, pharmacokinetics change during infancy and childhood, with the greatest changes occurring during the first month of life. Aspects of developmental physiology which may affect drug therapy include drug bioavailability, renal and hepatic clearance, and changes in volume of distribution and plasma protein binding. Drug bioavailability may be affected by multiple factors in the neonatal gastrointestinal tract. The newborn has a neutral gastric pH. In addition, delayed gastric emptying, increased intestinal transit time, and frequent feeding affects drug absorption in the neonate. Drugs such as nelfinavir NLF ; may be metabolized in the neonate by fetal intestinal CYP34A7.5 Renal clearance starts out quite low in the newborn and rapidly increases during the first month of life. In childhood, renal function approaches adult levels by age 3 to 4.5 Most hepatic metabolic functions are significantly reduced in the neonate and do not reach adult levels until later in childhood. Activity of many hepatic metabolic enzymes exceeds adult values in early childhood declining to adult values after puberty.5 Total body water is higher in the neonate and is higher in the preterm than full-term neonate, resulting in an increased volume of distribution and thus requiring higher dosing of some drugs. Lower plasma protein concentration and protein-binding avidity requires other drugs to be dosed at lower levels.5 The PK parameters of multiple antiretroviral drugs in pediatric patients are known. The nucleoside reverse transcriptase inhibitor NRTI ; zidovudine ZDV ; has undergone extensive PK evaluation due to its use in prevention of perinatal transmission. Clearance of ZDV is diminished in neonates with total body clearance rates slower in the first 14 days of life and slower in preterm versus term infants. The resulting differences in half-life result in different dosing recommendations of neonatal ZDV based on gestational and chronological age. Other NRTIs such as lamivudine 3TC ; and abacavir ABC ; have varied clearance rates between neonates, infants 1-3 months of age, and infants older than 3 months. The NNRTIs viramune NVP ; and efavirenz EFV ; are primarily hepatically metabolized. Therefore with hepatic enzyme maturation comes different rates of clearance in the various pediatric groups. NVP when given to the mother during the intrapartum period results in a long half-life in the newborn. After birth, neonatal dosing results in a much shorter halflife. Since hepatic clearance of this drug exceeds adult values in early childhood, higher dosing of NVP is needed until age 9 in HIVinfected children. Similar to NVP, EFV also requires higher dosing in young children. Since the protease inhibitor NLF was available in powder form quickly after its release, much is known about its PK parameters in children. Like all PIs, NLF is hepatically metabolized and its kinetic features exhibit a great degree of inter-individual variability in adults. This variability is even more accentuated in children and particularly infants as hepatic function matures. Clearance rates generally are significantly higher in children than adults. Furthermore, clearance is not only affected by age but by weight, with children less than 25 kilograms requiring higher and more frequent dosing. Absorption is also variable since bioavailability of NLF is affected by food intake. 5 Any new ARV introduced must have PK data collected in multiple pediatric age groups with particular attention paid to how changes in body mass, gastrointestinal absorption, plasma protein concentration, hormonal changes of puberty, as well as renal and hepatic clearance, affect PK parameters. Adverse Events In general, clinical trials have shown that ARVs are well tolerated in pediatric patients. The adverse event profile is relatively similar to that of adults with few exceptions. Gastrointestinal side effects such as nausea, vomiting and diarrhea are approximately as frequent in pediatric patients as in adult patients. The incidence of rash is similar between children and adult patients treated with NNRTIs. Central nervous system complaints with EFV, however, are less frequent in children than adults.1, 6-8 2.
Lifestyle drugs may give the desired containment of treatment rates. It is also important for health plans to realize that promotional variables other than the prominent drug advertising highly influence prescription choice. Free samples are of particular interest. The vast majority of patients do not switch brands if the prescribed therapy yields satisfactory results, therefore the initial choice of the drug is crucial. Given the observed strong brand loyalty, it is not surprising that pharmaceutical manufacturers shower physicians with free samples. Physicians often accept detailing visits because they do appreciate free samples they can later distribute to their patients. But if patients respond well to the free samples, they are highly likely to continue with that brand. This would suggest that starter packs might provide the extra incentive to choose formulary drugs or generics, if available, at the time of diagnosis. DTCA, on the other hand, is given too much credit for influencing what drugs are utilized most heavily. Effective treatment for HIV requires a combination of at least three drugs. The best time to start treatment with HIV antiretroviral medication is controversial. Some medical authorities believe starting antiviral therapy soon after testing positive for HIV will help the body fight HIV. However, many practitioners prefer to wait until HIV viral load is between 30, 000-50, 000 copies, or the CD 4 count is between 300-400 before starting therapy. Antiretroviral medications include: Nucleoside Reverse Transcriptase Inhibitors NRTIs ; : examples are AZT Retrovir ; , d4T Zerit ; , ddI Videx Non-Nucleoside Reverse Transcriptase Inhibitors NNRTIs ; : examples are efavirenz Sustiva ; , nevirapine Viram7ne and Protease Inhibitors Pis ; examples are ritonavir Norvir ; , indinavir Crixivan ; . Many of these medications can have serious side effects including fatigue, fevers, headaches, rashes, depression and more. Since the liver metabolizes these drugs it is extremely important that people taking them be monitored for potential liver toxicity. The stepped-care model of depression draws attention to the different needs that depressed people have depending on the characteristics of their depression and their personal and social circumstances and the responses that are required from services. It provides a framework in which to organise the provision of services supporting both patients and carers, and healthcare professionals in identifying and accessing the most effective interventions see Figure 2.

Because of the late hour, it was agreed that all remaining items on the agenda would be postponed until the next Medical Control Committee meeting. The meeting was adjourned by Dr. DesChamps and pimozide. Of fat on average in these studies, there does appear to be a subset of people who do have abnormal accumulation of visceral abdominal fat with or without buffalo hump, breast enlargement, and excess fat in the neck and upper chest. The picture remains somewhat confusing, but it is fair to say that the term lipodystrophy, which does not accurately describe the type of change in fat, is falling out of favor in the medical community. In thinking about possible treatments for these changes in fat distribution, it is best to think about lipoatrophy and fat accumulation as separate processes that might both be occurring within an individual. But first it's worth considering why we might want to treat these changes in fat. Among the obvious reasons are that people with altered fat distribution are usually quite concerned about the change in their appearance, especially those who have lost fat in the face. Their selfesteem may be affected, and they may feel that their HIV status will be obvious to others. These concerns may cause some people to stop or skip doses of their antiretrovirals or even prevent them from starting HIV therapy when it is needed. People who have lost significant fat from the buttocks may have discomfort when sitting; women with breast enlargement may develop back pain. Others with increased neck fat may have difficulty moving their heads or with posture. In addition, the metabolic problems that often accompany the fat changes have potential to increase the risk of diabetes and heart disease. Treating the fat changes could have favorable effects on these metabolic disturbances and reduce the risk of these complications. Treatment of Lipoatrophy Switching Antiretrovirals A number of studies indicate that use of either Zerit or Retrovir AZT also in Combivir and Trizivir ; increases the lik elihood of developing lipoatrophy. Other drugs in this class known affectionately as "nukes" ; Epivir, Ziagen, Viread do not appear to be linked to lipoatrophy. It is possible that using a protease inhibitor PI ; with either Zerit or Retrovir speeds up the loss of fat, but this has not been proven conclusively. Although some studies have suggested that PIs may play a role in lipoatrophy, most studies that have looked at switching from a PI to different type of drug, such as a "non-nuke" like Sustiva or Viramune, have not shown gains of fat. phy, compared to only 17% of those on Kaletra plus two nukes and 9% taking Sustiva and Kaletra alone. But the lipoatrophy was mainly seen in those taking Zerit 42% ; or Retrovir 27% ; there was no significant difference in lipoatrophy between those taking Viread and those not taking any nukes. While the choice of nuke was important, overall twice as many people taking Sustiva developed lipoatrophy compared to those taking Kaletra, regardless of which nuke they took. But those who took Sustiva and Kaletra without any nukes saw their blood lipids cholesterol and triglycerides ; rise significantly more than those taking nukes. These results are in contrast to a prior study that found higher rates of lipoatrophy in patients taking the PI Viracept compared to Sustiva. Taken together, these results indicate that it may be the particular combination of drugs that is most important, rather than which class they belong to. The impact of ACTG 5142 on first-line treatment recommendations, if any, remains to be seen it will be important to tease out exactly which combinations have the least chance of lipoatrophy without increasing blood lipids. And of course, which regimens work best: 89% of people taking Sustiva had viral loads below 50, compared to 77% of those on Kaletra another surprising result. As a result of some of these observations, researchers have looked at the effects of switching from HIV drugs that are linked to lipoatrophy to other drugs. In most of these studies, people who switched from Zerit or Retrovir to Ziagen or Viread had modest gains in fat in their arms and legs compared to people who stayed on their original therapy. While researchers reported these gains using special scans, patients did not always notice changes in their appearance. Many of the studies lasted a year or less, so it is possible that with more time people who switched from the offending drug will gain enough fat back to make a noticeable difference. continued on next page. Single-dose viramund was found to be very effective in preventing mother-to-child transmission, and is commonly used now in the developing world for that purpose, but the full ramifications of widespread nnrti resistance among women in the developing world is not yet completely understood and orinase. Lipitor, can more substantially influence these cholesterol levels. Pravachol may be the statin least susceptible to interaction with CYP3A4 inhibitors. A recent abstract reported that, in HIV negative people, the median 24-hour concentration area-underthe-curve for Pravachol co-administered with Norvir Fortovase decreased a median of 0.5 fold while there was a 4.5-fold increase for Lipitor and 32-fold increase for Zocor. Potential problems include significantly increased skeletal muscle toxicity due to increased levels of statins caused by CYP3A4 inhibition by HIV PIs and lower levels of PIs possibly leading to virologic failure--increased viral load ; caused by p450 induction [liver function] by statins. Elevated levels of statins have been associated with the development of rhabdomyolysis [a muscle disorder], such that the FDA has issued warnings about using these medications in patients known to be taking an agent which inhibits their metabolism. Similarly, interactions between statin agents and the CYP3A4 inducers Vuramune and Sustiva may occur, possibly resulting in lower serum levels of statins!
