Abstract
Statins are hypolipidaemic in human immunodeficiency virus (HIV) positive individuals. However, their effect on all-cause mortality and rate of discontinuation is unclear. We conducted a systematic review to evaluate the impact of statins on all-cause mortality, discontinuation rates, and risk of adverse effects among HIV patients on highly active antiretroviral therapy (HAART). We searched four electronic databases from inception until October 2021 for trials and cohort studies evaluating the effects of statin treatment versus placebo in HIV patients. Forty-seven studies involving 91,594 patients were included. Statins were associated with significantly lower risk of discontinuation (RR, 0.701; 95% CI 0.508-0.967; p = 0.031). The risk of all-cause mortality (RR, 0.994; 95% CI 0.561-1.588; p = 0.827), any adverse effects (RR, 0.780; 95% CI 0.564-1.077; p = 0.131) and, diabetes mellitus (RR, 0.272; 95% CI 0.031-2.393; p = 0.241) with statin treatment were lower but not statistically significant compared to placebo/control. Statin treatment was associated with a trend of higher but statistically insignificant risk of myalgia (RR, 1.341; 95% CI 0.770-2.333; p = 0.299), elevated creatine kinase (RR, 1.101; 95% CI 0.457-2.651; p = 0.830) and liver enzyme activities (RR, 1.709; 95% CI 0.605-4.831; p = 0.312). Clinicians should consider the nocebo effect in the effective management of PLWH on statins, who present with common adverse effects such as myalgia and, elevated levels of creatine kinase and liver enzymes.

Differences in statin utilization and lipid lowering by race, ethnicity, and HIV status in a real-world cohort of persons with human immunodeficiency virus and uninfected persons. Am Heart J 2019; 209:79-87. [PMID: 30685678 DOI: 10.1016/j.ahj.2018.11.012] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Accepted: 11/30/2018] [Indexed: 12/31/2022]
Abstract
BACKGROUND Risks for cardiovascular diseases, including myocardial infarction and stroke, are elevated in people with HIV infection (PWH). However, no trials of statin utilization with clinical cardiovascular disease (CVD) end points have been completed in PWH, and there are sparse real-world data regarding statin use and lipid-lowering effectiveness. We therefore used a unique cohort of PWH and uninfected controls to evaluate (1) differences in statin types used for PWH versus uninfected persons; (2) lipid lowering achieved by statin use for PWH versus uninfected persons; and (3) racial and ethnic disparities in appropriate statin use among PWH and uninfected persons. METHODS We analyzed a cohort of 5,039 PWH and 10,011 uninfected demographically matched controls who received care at a large urban medical center between January 1, 2000, and May 17, 2017. Medication administration records, prescription data, and validated natural language processing algorithms were used to determine statin utilization. Statins were categorized by generic active ingredient name and intensity (high, moderate, or low). Lipid values collected in routine clinical care were available for analysis. The first set of analyses was restricted to PWH and uninfected matched controls taking statins and compared (1) differences in statin type and (2) difference in cholesterol levels after versus before statin initiation by HIV status. For the second set of analyses, we first used prevalent CVD risk factors to determine participants with statin indications and then determined how many of these participants were taking statins. We then compared statin utilization among persons with indications for statins by race/ethnic group for PWH and uninfected matched controls using multivariable-adjusted logistic regression. RESULTS Among people prescribed statins, PWH were more likely than controls to have ever taken pravastatin (34.8% vs 12.3%, P < .001) or atorvastatin (72.2% vs 65.6%, P = .002) and less likely to have ever taken simvastatin (14.2% vs 39.5%, P < .001). Among PWH with indications for statin utilization, 55.7% of whites, 39.4% of blacks, and 45.8% of Hispanics were prescribed statins (P < .001). These differences in statin prescription by race/ethnicity remained significant after adjustment for demographics (including insurance status), cardiovascular risk factors, antiretroviral therapy use, HIV viremia, and CD4 count. These racial/ethnic disparities in statin utilization were less pronounced among uninfected persons. CONCLUSIONS Among PWH with statin indication(s), blacks and Hispanics were less likely than whites to have been prescribed a statin. These racial/ethnic disparities were less pronounced among uninfected persons. There were significant differences in type of statin used for PWH compared to uninfected matched controls. Future efforts addressing disparities in CVD prevention among PWH are warranted.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the therapeutic approach for lipodystrophy syndromes with conventional treatment options and metreleptin therapy in detail and to point out the current investigational treatments in development. RECENT FINDINGS The observation of leptin deficiency in patients with lipodystrophy and the potential of leptin replacement to rescue metabolic abnormalities in animal models of lipodystrophy were followed by the first clinical study of leptin therapy in patients with severe lipodystrophy. This and several other long-term studies demonstrated important benefits of recombinant human leptin (metreleptin) to treat metabolic abnormalities of lipodystrophy. These studies ultimately led to the recent FDA approval of metreleptin for the treatment of generalized lipodystrophy and EMA approval for both generalized and partial lipodystrophy. Additional research efforts in progress focus on novel treatment options, predominantly for patients with partial lipodystrophy. Current treatment of generalized lipodystrophy includes metreleptin replacement as an adjunct to diet and standard treatment approach for metabolic consequences of lipodystrophy. Beyond metreleptin, a number of different compounds and treatment modalities are being studied for the treatment of partial lipodystrophy.

Statin therapy and low-density lipoprotein cholesterol reduction in HIV-infected individuals after acute coronary syndrome: Results from the PACS-HIV lipids substudy. Am Heart J 2017; 183:91-101. [PMID: 27979047 DOI: 10.1016/j.ahj.2016.10.013] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2016] [Accepted: 10/17/2016] [Indexed: 01/09/2023]
Abstract
Knowledge about lipid interventions in secondary prevention in HIV-infected individuals is limited; studies are sparse. METHODS A prospective observational multicenter study enrolled 282 patients on statin 1 month after first acute coronary syndrome (ACS) (95 HIV-infected individuals, 187 HIV-uninfected). Data on fasting lipids (total cholesterol [TC], low-density lipoprotein cholesterol, high-density lipoprotein cholesterol [HDL-C], non-HDL-C, triglycerides, TC/HDL-C ratio) were collected over 3 years. The evolution of lipid concentrations was analyzed using mixed-effects models. Achievement of National Cholesterol Education Program Adult Treatment Panel III lipid goals and prescribed statin intensity was assessed. RESULTS Mean age of patients was 49.0 years, and 94% were men. Baseline lipids were similar in the 2 groups. Six months after first ACS, less low-density lipoprotein cholesterol reduction was observed in the HIV-infected GROUP (adjusted mean change -10.13; 95% CI -20.63 to 0.37; P=.06) than in the HIV-uninfected group (Adjusted mean change -38.51; 95% CI -46.00 to -31.04; P<.0001) Similar trends were observed for TC and non-HDL-C. After ACS, initial statin prescription for HIV-infected compared with HIV-uninfected individuals was more frequently a moderate-intensity statin (66% vs 45%) and less frequently a high-intensity statin (15% vs 45%). Over 3 years of follow-up, the proportion of HIV-infected patients receiving high-intensity statin remained persistently lower than the proportion observed in the HIV-uninfected group. CONCLUSIONS In this observational study, HIV-infected individuals after first ACS exhibited worse lipid profiles than controls particularly during the first 6 months while receiving less potent statins. Appropriate statin intensity should be prescribed in HIV-infected individuals with awareness of potential drug-drug interactions.

Abstract
PURPOSE OF REVIEW To evaluate evidence that statins reduce cardiovascular risk in patients living with HIV. RECENT FINDINGS Moderate to high-dose atorvastatin and rosuvastatin appear to reduce noncalcified coronary plaque volume and slow progression of carotid intima-media thickness in patients with treated HIV infection. Expected lipoprotein changes with statins on the background of modern antiretroviral therapy are similar to the general population. In addition to lipids, the statin benefit may be mediated in part by improvements in vascular inflammation and levels of T-cell and monocyte activation. One concern is the potential for rosuvastatin to cause insulin resistance. Decisions to prescribe statins must be done in the context of global risk assessment, but traditional risk calculators such as the Framingham Risk Score or the American College of Cardiology/American Heart Association pooled-risk equations underestimate risk in this population. Furthermore, many patients with subclinical disease would not be recommended for statins according to the most recent American College of Cardiology/American Heart Association guidelines. SUMMARY Statins are likely to improve cardiovascular outcomes for patients with HIV, but results of the first outcome study are not expected until 2020. In the meantime, clinicians should individualize statin prescriptions, and should consider using more potent statins (rosuvastatin, atorvastatin, and pitavastatin) when possible.

Abstract
Patients infected with HIV have a high risk of developing dyslipidemia. Effective therapeutic strategies can be challenging due to an increase risk of drug interactions and other comorbidities. Understanding the underlying pathophysiology and the principles of pharmacological and non-pharmacological therapeutic interventions can be of value in the appropriate management of dyslipidemia in the HIV-infected patient.

Abstract
Background HIV-infected patients on antiretroviral therapy frequently develop dyslipidemias and, despite therapy with potent lipid-lowering agents, a high percentage does not achieve guideline recommended lipid targets. In this study, we examined the efficacy of combination treatment with a statin and the cholesterol transport blocker, ezetimibe, vs. monotherapy with a statin in HIV-infected patients not achieving lipid goals. Methods This was a 12-week, prospective, randomized, open-label clinical trial. Patients were eligible if they had an apolipoprotein B (apoB) >0.80 g/L despite therapy with rosuvastatin 10 mg daily for a minimum of 12 weeks. Patients were randomized to take ezetimibe 10 mg/rosuvastatin 10 mg or rosuvastatin 20 mg for 12 weeks. Percentage and absolute change in apoB (primary outcome), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, apoliporpotein A1 (apoA1), apoB/apoA1, TC/HDL-C, atherogenic index of plasma (API), and high-sensitivity C-reactive protein (hsCRP) were compared. Changes in safety parameters (such as AST, ALT, CK) and clinical symptoms were also assessed. Results Forty-three patients (23 on ezetimibe 10 mg/rosuvastatin 10 mg and 20 on rosuvastatin 20 mg) completed the trial. Baseline characteristics did not differ between the groups. Significant improvements in apoB were seen with both ezetimibe plus rosuvastatin (mean of -0.17 g/L, p < 0.001) and rosuvastatin 20 mg (mean of -0.13 g/L, p = 0.03) treatment groups, but did not differ between groups (p = 0.53). Significant between-group differences were observed for mean TC (-1.01 mmol/L vs. -0.50 mmol/L, p = 0.03), TG (-0.62 mmol/L vs -0.17 mmol/L, p = 0.03), and non-HDL-C (-0.97 mmol/L vs. -0.53 mmol/L, p = 0.03) all in favour of the ezetimibe plus rosuvastatin group. Two patients, both in the rosuvastatin 20 mg group, experienced mild myalgias; neither discontinued the study. Conclusions The addition of ezetimibe to rosuvastatin appears to be safe in patients with HIV. Furthermore, the combination of ezetimibe and rosuvastatin improved TG, AIP and non-HDL cholesterol levels more than a dose increase in rosuvastatin in patients with HIV-associated dyslipidemia.

Abstract
Lipodystrophies are rare acquired and genetic disorders characterized by the selective loss of adipose tissue. One key metabolic feature of patients with congenital inherited lipodystrophy is hypertriglyceridemia. The precise mechanisms by which the lack of adipose tissue causes dyslipidemia remain largely unknown. In recent years, new insights have arisen from data obtained in vitro in adipocytes, yeast, drosophila, and very recently in several genetically modified mouse models of generalized lipodystrophy. A common metabolic pathway involving accelerated lipolysis and defective energy storage seems to contribute to the dyslipidemia associated with congenital generalized lipodystrophy syndromes, although the pathophysiological changes may vary with the nature of the mutation involved. Therapeutic management of dyslipidemia in patients with lipodystrophy is primarily based on specific approaches using recombinant leptin therapy. Preclinical studies suggest a potential efficacy of thiazolidinediones that remains to be assessed in dedicated clinical trials.

Abstract
Leptin is a hormone secreted by adipocytes that regulates energy metabolism via peripheral action on glucose synthesis and utilization as well as through central regulation of food intake. Patients with decreased amounts of fat in their adipose tissue (lipoatrophy) will have low leptin levels, and hypoleptinemic states have been associated with a variety of metabolic dysfunctions. Pronounced complications of insulin resistance, dyslipidemia and fatty liver are observed in patients suffering from congenital or acquired generalized lipodystrophy while somewhat less pronounced abnormalities are associated with human immunodeficiency virus (HIV) and the use of highly active antiretroviral therapy, the so-called HIV-associated lipodystrophy. Previous uncontrolled open-label studies have demonstrated that physiological doses of leptin repletion have corrected many of the metabolic derangements observed in subjects with rare fat maldistribution syndromes such as generalized lipodystrophy. In the much more commonly encountered HIV-associated lipodystrophy, leptin replacement has been shown to decrease central fat mass and to improve insulin sensitivity, dyslipidemia, and glucose levels. The United States Food and Drug Administration has recently granted approval for recombinant leptin therapy for congenital and acquired generalized lipodystrophy, however large, well-designed, placebo-controlled studies are needed to assess long-term efficacy, safety and adverse effects of leptin replacement. In this review, we present the role of leptin in the metabolic complications of congenital and acquired lipodystrophy and discuss current and emerging clinical therapeutic uses of leptin in humans with lipodystrophy.

Abstract
BACKGROUND Rosuvastatin is one of the most potent statins and is currently widely prescribed. It is therefore important to know the dose-related magnitude of effect of rosuvastatin on blood lipids. OBJECTIVES Primary objective To quantify the effects of various doses of rosuvastatin on serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, non-HDL-cholesterol and triglycerides in participants with and without evidence of cardiovascular disease. Secondary objectives To quantify the variability of the effect of various doses of rosuvastatin.To quantify withdrawals due to adverse effects (WDAEs) in the randomized placebo-controlled trials. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 10 of 12, 2014 in The Cochrane Library, MEDLINE (1946 to October week 5 2014), EMBASE (1980 to 2014 week 44), Web of Science Core Collection (1970 to 5 November 2014) and BIOSIS Citation Index (1969 to 31 October 2014). No language restrictions were applied. SELECTION CRITERIA Randomized controlled and uncontrolled before-and-after trials evaluating the dose response of different fixed doses of rosuvastatin on blood lipids over a duration of three to 12 weeks. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility criteria for studies to be included and extracted data. WDAEs information was collected from the placebo-controlled trials. MAIN RESULTS One-hundred and eight trials (18 placebo-controlled and 90 before-and-after) evaluated the dose-related efficacy of rosuvastatin in 19,596 participants. Rosuvastatin 10 to 40 mg/day caused LDL-cholesterol decreases of 46% to 55%, when all the trials were combined using the generic inverse variance method. The quality of evidence for these effects is high. Log dose-response data over doses of 1 to 80 mg, revealed strong linear dose-related effects on blood total cholesterol, LDL-cholesterol and non-HDL-cholesterol. When compared to atorvastatin, rosuvastatin was about three-fold more potent at reducing LDL-cholesterol. There was no dose-related effect of rosuvastatin on blood HDL-cholesterol, but overall, rosuvastatin increased HDL by 7%. There is a high risk of bias for the trials in this review, which would affect WDAEs, but unlikely to affect the lipid measurements. WDAEs were not statistically different between rosuvastatin and placebo in 10 of 18 of these short-term trials (risk ratio 0.84; 95% confidence interval 0.48 to 1.47). AUTHORS' CONCLUSIONS The total blood total cholesterol, LDL-cholesterol and non-HDL-cholesterol-lowering effect of rosuvastatin was linearly dependent on dose. Rosuvastatin log dose-response data were linear over the commonly prescribed dose range. Based on an informal comparison with atorvastatin, this represents a three-fold greater potency. This review did not provide a good estimate of the incidence of harms associated with rosuvastatin because of the short duration of the trials and the lack of reporting of adverse effects in 44% of the placebo-controlled trials.

Abstract
BACKGROUND AND AIMS Many patients treated with statins are considered statin-resistant because they fail to achieve adequate reduction of low density lipoprotein cholesterol (LDL-C) levels. Some patients are statin-intolerant because they are unable to tolerate statin therapy at all or to tolerate a full therapeutic statin dose because of adverse effects, particularly myopathy and increased activity of liver enzymes. RESULTS The resistance to statins has been associated with polymorphisms in the 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA-R), P-glycoprotein (Pg-P/ABCB1), breast cancer resistance protein (BCRP/ABCG2), multidrug resistance-associated proteins (MRP1/ABCC1 and MRP2/ABCC2), organic anion transporting polypeptides (OATP), RHOA, Nieman-Pick C1-like1 protein (NPC1L1), farnesoid X receptor (FXR), cholesterol 7alpha-hydroxylase (CYP7A1), Apolipoprotein E (ApoE), proprotein convertase subtilisin/kexin type 9 (PCSK9), low density lipoprotein receptor (LDLR), lipoprotein (a) (LPA), cholesteryl ester transfer protein (CETP), and tumor necrosis factor α (TNF-α) genes. However, currently, there is still not enough evidence to advocate pharmacogenetic testing before initiating statin therapy. Patients with inflammatory states and HIV infection also have diminished LDL-C lowering as a response to statin treatment. Pseudo-resistance due to nonadherence or non-persistence in real-life circumstances is probably the main cause of insufficient LDL-C response to statin treatment. CONCLUSIONS If a patient is really statin-resistant or statin-intolerant, several other treatment possibilities are nowadays available: ezetimibe alone or in combination with bile acid sequestrants, and possibly in the near future mipomersen, lomitapide, or monoclonal antibodies against PCSK9.

Abstract
OBJECTIVES To evaluate the 5 year effects of an intensive intervention versus the standard-of-care intervention on cardiovascular risk factors in HIV-infected patients on antiretroviral therapy (ART). METHODS This was a longitudinal study including virologically suppressed patients with at least two cardiovascular risk factors or a Framingham risk score ≥10%. Intensive and standard-of-care interventions aimed for low-density lipoprotein cholesterol (LDL-C) <100 and <130 mg/dL, respectively, by using lipid-lowering drugs. In the intensive group, switching ART when needed to achieve the LDL-C target and low-dose aspirin were used. Achievement of LDL-C targets and changes in carotid intima-media thickness (cIMT) and cardiovascular biomarkers were compared between groups at different timepoints through a 5 year period. RESULTS Twenty-two and 25 patients in the intensive and standard intervention groups, respectively, were followed up. At 5 years, pre-specified LDL-C targets were achieved in 82% (intensive) and 81% (standard of care) of patients. The median (IQR) change in LDL-C in the intensive and standard intervention groups was -78 (-96/-39.7) and -49 (-72/-3) mg/dL, respectively (P = 0.04), and in the Framingham score was -4% (-8%/-1%) and 0% (-4%/6.5%), respectively (P = 0.01). There were no significant intra- or between-group changes in cIMT measurements. A significant decrease was observed in the intensive and standard groups in interleukin 6 (P = 0.001 and P = 0.002, respectively) and in tumour necrosis factor α (P = 0.023 and P = 0.052, respectively). Asymptomatic creatine phosphokinase elevations were observed in two patients assigned to the standard intervention group. CONCLUSIONS An intensive intervention on cardiovascular risk factors in HIV-infected patients on ART was feasible, safe and capable of achieving LDL-C targets in the long term. Both intensive and standard interventions were accompanied by antiatherosclerotic changes in inflammatory cytokines and lack of cIMT progression.

Abstract
Lipodystrophy is a medical condition characterized by complete or partial loss of adipose tissue. Not infrequently, lipodystrophy occurs in combination with pathological accumulation of adipose tissue at distinct anatomical sites. Patients with lipodystrophy exhibit numerous metabolic complications, which indicate the importance of adipose tissue as an active endocrine organ. Not only the total amount but also the appropriate distribution of adipose tissue depots contribute to the metabolic state. Genetic and molecular research has improved our understanding of the mechanisms underlying lipodystrophy. Circulating levels of hormones secreted by the adipose tissue, such as leptin and adiponectin, are greatly reduced in distinct subpopulations of patients with lipodystrophy. This finding rationalizes the use of these adipokines or of agents that increase their circulating levels, such as peroxisome proliferator-activated receptor γ (PPARγ) agonists, for therapeutic purposes. Other novel therapeutic approaches, including the use of growth hormone and growth-hormone-releasing factors, are also being studied as potential additions to the therapeutic armamentarium. New insights gained from research and clinical trials could potentially revolutionize the management of this difficult-to-treat condition.

Abstract
HIV-infected patients are living decades longer than before owing to combination antiretroviral therapy. However, complications are emerging in this population at rates higher than the general population, including cardiovascular disease (CVD). HIV-infected patients have many traditional risk factors that account for a significant part of their increased risk of CVD. However, HIV factors, including complications from antiretroviral therapy and increased inflammation associated with chronic HIV infection, also play a role. Clinicians need to be ever-vigilant to calculate and help attenuate any modifiable CVD risk factors for each HIV-infected individual.

Abstract
BACKGROUND dyslipidemia is common and is often treated with 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors (statins). Little is known about the comparative effectiveness of statins among human immunodeficiency virus (HIV)-infected patients. This study compared the effectiveness and toxicity of statins among HIV-infected patients in clinical care. METHODS we conducted a retrospective cohort study of patients starting their initial statin medications at 2 large HIV clinics (N = 700). The primary observation was change in lipid levels during statin therapy. Secondary observations included whether individualized National Cholesterol Education Program (NCEP) goals for low density lipoprotein cholesterol (LDL-C) and non-high density lipoprotein cholesterol (non-HDL-C) levels were reached, and toxicity rates. We used linear regression to examine change in lipid levels, controlling for baseline lipid values and demographic and clinical characteristics. We conducted secondary analyses using propensity scores to address confounding by indication. RESULTS the most commonly prescribed statins were atorvastatin (N = 303), pravastatin (N = 280), and rosuvastatin (N = 95). One year after starting a statin therapy, patients who received atorvastatin or rosuvastatin had significantly greater decreases in total cholesterol, LDL-C, and non-HDL-C than patients on pravastatin. The likelihood of reaching NCEP goals for LDL-C levels was higher with the use of rosuvastatin (OR 2.1; P = .03) and atorvastatin (odds ratio [OR], 2.1; P = .001) compared with that of pravastatin. The likelihood of reaching NCEP goals for non-HDL-C levels was higher for rosuvastatin (OR 2.3; P = .045) but not atorvastatin (OR, 1.5; P = .1) compared with pravastatin. Toxicity rates were similar for all 3 statins: 7.3% for atorvastatin, 6.1% for pravastatin, and 5.3% for rosuvastatin. CONCLUSIONS our findings suggest that atorvastatin and rosuvastatin are preferable to pravastatin for treatment of HIV-infected patients with dyslipidemia, due to greater declines in total cholesterol, LDL-C, and non-HDL-C, with similar lower toxicity rates.

Abstract
IMPORTANCE OF THE FIELD Patients infected with HIV are at high risk for dyslipidemia, insulin resistance and cardiovascular disease. Therapies to reverse these risks are complex, sometimes controversial, and not uniformly effective. AREAS COVERED IN THIS REVIEW Pathophysiology of the lipid abnormalities in HIV is discussed, including the causes of alterations in triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and insulin resistance. We discuss the therapy of dyslipidemia in HIV using a combination of available clinical evidence and expert opinion based on extensive clinical experience, with discussions of lifestyle intervention and diet, conventional pharmacotherapy with lipid-lowering medications including statins, fibrates, niacin and thiazolidinediones for dyslipidemia, and newer therapeutic approaches including omega fatty acids, acipimox, growth hormone and leptin. WHAT THE READER WILL GAIN A detailed understanding of the pathophysiology and rational or evidence-based approach to therapy of lipid abnormalities in patients infected with HIV. TAKE HOME MESSAGE Treatment of dyslipidemia in patients with HIV is challenging and complicated by the risk of drug interactions. Appropriate therapy requires a sound understanding of pathophysiology and the principles of pharmacological and nonpharmacological therapeutic interventions. An evidence-based approach that combines lifestyle changes and drugs that are both safe and effective, singly and in combination, is described.

Abstract
OBJECTIVE This article reviewed the collective evidence from routine clinical practice to summarize the existing literature on the effectiveness of rosuvastatin in treating hypercholesterolemia. METHODS A comprehensive Medline literature search identified all published articles, in all languages, from January 2003 through September 2008 on the use of rosuvastatin in the usual-care setting. The search identified 60 articles, and 16 articles were included in this review because they were observational and non-interventional and included sufficient data specific to rosuvastatin. Excluded articles were clinical trials, cost-effectiveness models, safety, reviews, pharmacokinetics, abstracts or editorials only, or all statins combined. Included rosuvastatin articles were categorized as (1) effectiveness in general population and (2) effectiveness in special populations (e.g., elderly, diabetes). RESULTS Seven studies consistently showed that diverse patients from different geographic regions who were newly initiated on rosuvastatin had significantly greater reduction in low-density lipoprotein cholesterol (LDL-C) (29-52%) compared with patients treated with other statins (16-43%). LDL-C goal attainment as recommended by National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III or European Society of Cardiology (ESC) guidelines was consistently and significantly higher among patients treated with rosuvastatin (64-81%) compared with patients treated with other statins (34-73%). Rosuvastatin-treated patients with diabetes or HIV or who were elderly had significantly greater LDL-C reduction and LDL-C goal attainment compared with patients treated with other statins. LIMITATIONS Channeling bias or confounding by indication may have influenced the results of the real-world studies, if physicians reserve rosuvastatin for sicker or more difficult to treat patients. CONCLUSIONS There is a strong and consistent body of evidence demonstrating the effectiveness of rosuvastatin in lowering LDL-C and LDL-C goal attainment in real life compared with other statins at commonly prescribed doses, which reflects the existing evidence from clinical trials.

Abstract
Metabolic abnormalities associated with the treatment of human immunodeficiency virus (HIV) infection are well-recognized problems that increase cardiovascular risk. As a result of the complexity of treating both HIV- and antiretroviral-related comorbidities, strategies that improve adverse drug events while maintaining viral control are in critical need. Although guidelines have somewhat helped in the general approach and in first-line strategies for managing dyslipidemia in patients receiving antiretrovirals, a paucity of data exist to guide clinicians in treating patients whose conditions are refractory to first-line options or who are at substantial risk for cardiovascular events. Further complicating the choice of lipid-lowering strategy is the lack of randomized controlled data from the HIV-affected population and a concern about clinically significant drug-drug interactions. We describe an HIV-infected patient with efavirenz-associated dyslipidemia at very high cardiovascular risk who had not achieved his primary or secondary lipid goals despite 2 years of treatment in a lipid specialty clinic. Lipid control was accomplished in 10 weeks with a targeted, stepwise approach of switching efavirenz to nevirapine, followed by rosuvastatin 20 mg/day, which was sustained for at least 10 months. Of most importance, this outcome was achieved without any clinically significant alteration in virologic or immunologic control. This case report highlights the potential for a pharmacist-guided, multistep approach that addresses HIV-related dyslipidemia and incorporates the pharmacokinetic literature to guide lipid-lowering therapy and promote the attainment of goals based on current standards of care.
