Abstract: In the UK, the annual cost of treatment and care for people with human immunodeficiency virus (HIV)/acquired immune deficiency virus (AIDS) rose by over 600% from £104 million in 1997 to £762 million in 2010; approximately two-thirds of the £762 million cost of treatment and care in 2010 was for the procurement of antiretrovirals and other related drugs. The number of people accessing care for HIV/AIDS rose from 22,000 in 2000 to 65,000 in 2009. Adoption of “test and treat” guidelines for treating all HIV-infected people with antiretro-virals would further increase the burden of costs. Given the current economic situation, there is now a new focus on strategies for treatment and care of people with HIV-1 infection which can maintain efficacy but at a lower cost. In this review, we propose three strategies which could potentially lower the costs of treatment and care, ie, stopping testing CD4 counts for patients with full HIV RNA suppression on antiretroviral treatment and recent CD4 counts above 350 cells/ L; more widespread use of generic antiretrovirals as replacements for patients currently taking patented versions; and use of darunavir-ritonavir monotherapy as a switch option for patients with full HIV RNA suppression on other antiretrovirals and no history of virological failure. However, it is important that high standards of clinical care are maintained despite cost-saving measures. Antiretrovirals with generic alternatives may have toxicity issues, eg, zidovudine and nevirapine. There could be ethical issues in starting patients on these drugs if they are currently tolerating other treatments. The use of darunavir-ritonavir monotherapy is not consistently recommended in international HIV treatment guidelines.Keywords: health economics, generics, darunavir-ritonavir monotherapy, nucleoside analogs, non-nucleoside reverse transcriptase inhibitors
IntroductionIn the UK, the annual cost of treatment and care for people with human immunode-ficiency virus (HIV)/acquired immune deficiency virus (AIDS) rose by over 600% from £104 million in 1997 to £762 million in 2010; approximately two-thirds of the £762 million cost of treatment and care in 2010 was for the procurement of antiretro-virals and other related drugs.1 The number of people accessing care for HIV/AIDS rose from 22,000 in 2000 to 65,000 in 2009.2 In 2000, there were an estimated 14,000 people receiving antiretroviral treatment in the UK; by 2009, this number had risen to 51,000. In 2010, there were 6750 people newly diagnosed with HIV infection in the UK compared with 500 HIV-related deaths. During the past 10 years, there has been a linear rise in the number of people diagnosed with HIV in the UK and starting antiretroviral treatment, with no sign of a plateau.2 If current trends continue, we can

SINCE THE FIRST ANTIRETROVIRALdrug was approved 25 years ago,improvements in the potency,tolerability, simplicity, and avail-
ability of antiretroviral therapy (ART)have resulted in dramatically reducednumbers of opportunistic diseases anddeaths where ART is accessible.1 Newdata show that viral suppression due toART results in decreased human immu-nodeficiencyvirus (HIV) transmissiononindividual2 and population levels1 andthat, when used consistently by HIV-uninfected persons, ART also may pro-vide protection against HIV infec-tion.3-5 Together, these developmentshave translated into newly articulated vi-
sions of the “beginning of the end ofAIDS.”6 This revision of the Interna-tional Antiviral (formerly AIDS) Society–
USA (IAS-USA) guidelines reflects newdata informing consideration of when toinitiate ART, new options for initial and
CME available online atwww.jamaarchivescme.comand questions on p 413.
Context New trial data and drug regimens that have become available in the last 2years warrant an update to guidelines for antiretroviral therapy (ART) in human immu-nodeficiency virus (HIV)–infected adults in resource-rich settings.
Objective To provide current recommendations for the treatment of adult HIV in-fection with ART and use of laboratory-monitoring tools. Guidelines include when tostart therapy and with what drugs, monitoring for response and toxic effects, specialconsiderations in therapy, and managing antiretroviral failure.
Data Sources, Study Selection, and Data Extraction Data that had been pub-lished or presented in abstract form at scientific conferences in the past 2 years were sys-tematically searched and reviewed by an International Antiviral Society–USA panel. Thepanel reviewed available evidence and formed recommendations by full panel consensus.
Data Synthesis Treatment is recommended for all adults with HIV infection; the strengthof the recommendation and the quality of the evidence increase with decreasing CD4cell count and the presence of certain concurrent conditions. Recommended initial regi-mens include 2 nucleoside reverse transcriptase inhibitors (tenofovir/emtricitabine or aba-cavir/lamivudine) plus a nonnucleoside reverse transcriptase inhibitor (efavirenz), a ritonavir-boosted protease inhibitor (atazanavir or darunavir), or an integrase strand transfer inhibitor(raltegravir). Alternatives in each class are recommended for patients with or at risk ofcertain concurrent conditions. CD4 cell count and HIV-1 RNA level should be monitored,as should engagement in care, ART adherence, HIV drug resistance, and quality-of-careindicators. Reasons for regimen switching include virologic, immunologic, or clinical fail-ure and drug toxicity or intolerance. Confirmed treatment failure should be addressedpromptly and multiple factors considered.
Conclusion New recommendations for HIV patient care include offering ART to allpatients regardless of CD4 cell count, changes in therapeutic options, and modifica-tions in the timing and choice of ART in the setting of opportunistic illnesses such ascryptococcal disease and tuberculosis.JAMA. 2012;308(4):387-402 www.jama.com

tion disorders, or liver synthetic abnor-malities, there are no restrictions onART. In persons with hepatic failure,HIV PIs and selected other antiretro-viral drugs should be avoided or usedwith caution.
Hepatitis B Virus. The optimal ARTregimenforHIV-andHBV-coinfectedper-sons should include tenofovir andemtri-citabine (or lamivudine) as the NRTI
background. If renal insufficiencyoccursin HBV- and HIV-coinfected persons, areduced dose of tenofovir, but not of theothercomponents in the regimen, canbeused. Entecavir has been used safely incoinfected patients but has impairedactivityagainst lamivudine-resistantHBVand can select for M184V in HIV reversetranscriptase.98 In persons withoutlamivudine-resistantHBV,entecavir is analternative to tenofovir ifusedwitha fullysuppressiveantiretroviral regimen.Treat-ment of coinfected patients with regi-mens containing lamivudine or emtri-citabineas theonlyantiviralswithactivityagainst HBV provides suboptimal effi-cacy and usually results in NRTI-resistant HBV.99,100 Interferon alfa isapproved for treatment of chronic HBVinfection but has not been rigorouslytested in HIV-coinfected persons.
Hepatitis C Virus. Peginterferon alfaand ribavirin have been routinely usedin HIV- and HCV-coinfected persons.Ribavirin cannot be used with didano-sine and has overlapping toxicity withzidovudine. It is not clear whetherpeginterferon alfa plus ribavirin is lesseffective when used with abacavir thanwith tenofovir. The addition of the HCVPIs telaprevir or boceprevir to pegin-terferon alfa and ribavirin improvestreatment responses for genotype 1chronic HCV infection.101,102 Like-wise, preliminary phase 2 data in HIV-/HCV-coinfected persons showed supe-rior responses in those randomized topeginterferon alfa, ribavirin, and bo-ceprevir or telaprevir compared withpeginterferon alfa, ribavirin, and pla-cebo.103,104 As phase 3 studies are on-going and US Food and Drug Admin-istration (FDA) approval is pending forcoinfected patients, the superior re-sponses suggest either telaprevir or bo-ceprevir should be added to peginter-feron alfa/ribavirin when treatinggenotype 1 chronic HCV infection.
Drug-drug interactions between te-laprevir or boceprevir and antiretrovi-ral drugs may alter the optimal choiceof ART when their use is anticipated.Data from clinical trials continue toevolve but are currently insufficient toguide firm recommendations about rec-
ommended regimens. Available datasuggest that tenofovir, emtricitabine,raltegravir, and etravirine may be safelyused with boceprevir, and these drugsand rilpivirine, atazanavir/r, and efa-virenz (with increased telaprevir dose)may be used with telaprevir. However,HIV and HCV RNA levels should becarefully monitored when coadminis-tering these drugs, and evolving data ondrug-drug interactions should be con-sidered.105
Malignancy. Concomitant use of an-ticancer drugs and ART is associatedwith overlapping toxicities and the po-tential for substantial drug interac-tions due to elimination using CYP450routes of metabolism. Raltegravir-based regimens may be considered inthis setting because of their favorabledrug interaction profile.106 Recommen-dations for initial regimen in the abovespecific circumstances are summa-rized in BOX 2.
MONITORINGSuppression of plasma HIV-1 RNA toless than 50 copies/mL by 24 weeksshould occur with effective therapy, re-gardless of prior treatment experi-ence. No recent work has defined theoptimal frequency of monitoring in re-source-rich economies, despite the per-ception that such research could leadto substantial cost savings.107 There-fore, previous recommendations for fre-quency of CD4 cell count and HIV-1RNA monitoring have not changed.7
Recently introduced third-genera-tion HIV-1 RNA assays show a lowerlimit of quantification of 40 or 20 cop-ies/mL and can report qualitative RNAdetection below these cutoffs. Inaddition, many patients receiving stablesuppressive treatment show residualviremia of 1 to 10 copies/mL usingresearch-based assays. The source, sig-nificance, and optimal management ofdetectable viremia of less than 50 cop-ies/mL during treatment are poorly de-fined. Recent studies indicate thatdetectable HIV-1 RNA below the 50-copies/mL threshold predicted re-bound; however, the lower the viralload, the less likely it is to result in con-
Box 2. Recommendationsfor Initial Treatment in theSetting of SpecificConditions, With Strengthof Recommendations andQuality of Evidencea
In patients with or at high risk of car-diovascular disease, avoiding use ofabacavir, ritonavir-boosted lopina-vir, or ritonavir-boosted fosam-prenavir might be considered (BIIa).
In patients with reduced renal func-tion, tenofovir should be avoided, orif treatment for hepatitis B virus(HBV) coinfection is needed, dos-ing should be adjusted according tothe prescribing information (AIIa).
Given the increased risk of fragilityfractures, it may be prudent to avoidtenofovir as part of initial therapy inpostmenopausal women (BIIa).
The recommended initial ART regi-men in the setting of rifampin-based tuberculosis treatment is efa-virenz plus 2 nucleos(t)ide reversetranscriptase inhibitors (NRTIs)(AIa).
The recent recommendation for useof a 3-month, once-weekly regimenof isoniazid with rifapentine for treat-ment of latent TB infection is not rec-ommended for human immunode-ficiency virus (HIV)–infected patientsreceiving ART (BIII).
The ART regimen for HIV- and HBV-coinfected persons should includetenofovir and emtricitabine (or la-mivudine) as the NRTI background(AIIa).

firmed rebound.108,109 Evolution of vi-ral resistance can occur in the settingof low-level viremia. In 2 clinical trialsand a cohort analysis, new resistancemutations were detected in 37% and65%, respectively, of participants whodeveloped persistent low-level vire-mia.110,111 There is lack of consensus onmanagement of patients with HIV-1RNA levels between 50 and 200 copies/mL. The AIDS Clinical Trials Groupdefinition of virologic failure (con-firmed detectable HIV-1 RNA !200copies/mL after virologic suppres-sion) is commonly used.112 However,the optimal management of these pa-tients has not been determined.
There is limited evidence that ARTmodifications have an appreciable im-pact for patients with residual HIV-1RNA levels between 1 and 10 copies/mL.113 In practice, it is recommendedthat a detectable HIV-1 RNA level dur-ing therapy should be confirmed in asubsequent sample, usually drawnwithin 2 to 4 weeks, prior to makingmanagement decisions. However, theoptimal interval before repeating theHIV-1 RNA test after low-level vire-mia occurs has not been determined,and guidance about management strat-egies awaits further evidence.113
Publisheddata suggest that thepreva-lence of transmitted drug resistancehas remained stable worldwide and av-erages 11% in Europe and 15% in NorthAmerica.114 The presence of transmitteddrug resistance may be underestimatedif a resistance test is not performed earlyin infection. Although some mutationsmay persist in the long term (such as re-sistance mutations to NNRTIs), others(suchasM184V)thatconfer impairedfit-ness are quickly replaced by wild-typeHIVvariants.Patientswithresistancemu-tationsdetectedprior to initiationofARThavea3- to5-foldgreaterriskofvirologicfailure if a drug to which the virus is re-sistant is includedintheregimen,under-scoring the importanceofpretherapyre-sistancetesting.115Forconfirmedvirologicfailure, resistance testing is essential andshould, when possible, be performedwhile thepatient is still receiving the fail-ing regimen.7
Therapeutic drug monitoring is notrecommended for general care. How-ever, it may be useful in pregnantwomen, children, and patients with re-nal or liver impairment to minimizeoverexposure and adverse effects.Therapeutic drug monitoring also mayserve to assess adherence or to evalu-ate virologic failure in the absence ofresistance. Therapeutic drug monitor-ing may be useful if HCV PIs (telapre-vir or boceprevir) must be used withART for which the drug interactions areeither not clarified or are known tocause substantially increased or de-creased exposure of 1 of the drugs.Awareness of the potential for drug in-teractions with these agents is impor-tant.105,116,117
Increasing attention has been fo-cused on determinants, measurements,and interventions to improve entry intoand retention in care and monitoring ofand interventions to improve ART ad-herence. Recent recommendations havecovered these issues.9 National initia-tives118 have generated quality-of-care in-dicators, including in the area of fol-low-up of patients receiving treatment.An important quality-of-care factor ismanagement by physicians experi-enced in HIV medicine.119,120 Recom-mendations for monitoring are summa-rized in BOX 3.
TREATMENT-EXPERIENCEDPATIENTSNew regimens for ART-experienced pa-tients should include the most activedrugs available based on genotypicanalysis, treatment and adverse effecthistory, and availability of additionalclasses of drugs.
Initial Virologic FailureManagement of virologic failure of aninitial regimen is usually straightfor-ward, and a new regimen with 3 activedrugs can generally be constructed. Theregimen should be changed promptlyon confirmation of virologic failure.
Initial NNRTI-Based Regimens. De-laying a treatment change allows the ac-cumulation of additional NNRTI resis-tance mutations that may limit future
treatment options with etravirine andrilpivirine. Generating a new regimenwith 3 active agents is attainable usinga PI/r and active NRTIs. If choice is lim-

SINCE THE FIRST ANTIRETROVIRALdrug was approved 25 years ago,improvements in the potency,tolerability, simplicity, and avail-
ability of antiretroviral therapy (ART)have resulted in dramatically reducednumbers of opportunistic diseases anddeaths where ART is accessible.1 Newdata show that viral suppression due toART results in decreased human immu-nodeficiencyvirus (HIV) transmissiononindividual2 and population levels1 andthat, when used consistently by HIV-uninfected persons, ART also may pro-vide protection against HIV infec-tion.3-5 Together, these developmentshave translated into newly articulated vi-
sions of the “beginning of the end ofAIDS.”6 This revision of the Interna-tional Antiviral (formerly AIDS) Society–
USA (IAS-USA) guidelines reflects newdata informing consideration of when toinitiate ART, new options for initial and

Context New trial data and drug regimens that have become available in the last 2years warrant an update to guidelines for antiretroviral therapy (ART) in human immu-nodeficiency virus (HIV)–infected adults in resource-rich settings.
Objective To provide current recommendations for the treatment of adult HIV in-fection with ART and use of laboratory-monitoring tools. Guidelines include when tostart therapy and with what drugs, monitoring for response and toxic effects, specialconsiderations in therapy, and managing antiretroviral failure.
Data Sources, Study Selection, and Data Extraction Data that had been pub-lished or presented in abstract form at scientific conferences in the past 2 years were sys-tematically searched and reviewed by an International Antiviral Society–USA panel. Thepanel reviewed available evidence and formed recommendations by full panel consensus.
Data Synthesis Treatment is recommended for all adults with HIV infection; the strengthof the recommendation and the quality of the evidence increase with decreasing CD4cell count and the presence of certain concurrent conditions. Recommended initial regi-mens include 2 nucleoside reverse transcriptase inhibitors (tenofovir/emtricitabine or aba-cavir/lamivudine) plus a nonnucleoside reverse transcriptase inhibitor (efavirenz), a ritonavir-boosted protease inhibitor (atazanavir or darunavir), or an integrase strand transfer inhibitor(raltegravir). Alternatives in each class are recommended for patients with or at risk ofcertain concurrent conditions. CD4 cell count and HIV-1 RNA level should be monitored,as should engagement in care, ART adherence, HIV drug resistance, and quality-of-careindicators. Reasons for regimen switching include virologic, immunologic, or clinical fail-ure and drug toxicity or intolerance. Confirmed treatment failure should be addressedpromptly and multiple factors considered.
Conclusion New recommendations for HIV patient care include offering ART to allpatients regardless of CD4 cell count, changes in therapeutic options, and modifica-tions in the timing and choice of ART in the setting of opportunistic illnesses such ascryptococcal disease and tuberculosis.JAMA. 2012;308(4):387-402 www.jama.com
