Not an exotic bird in Brisbane!<\/p><\/div>\n<p style=\"text-align: left\">The biggest news this week at the 12th IAS Conference on HIV Science here in Brisbane, Australia, was the results of <a href=\"https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMoa2304146\">REPRIEVE<\/a>, a large randomized clinical trial conducted in people with HIV.<\/p>\n<p>It&#8217;s not a study of novel antiretroviral regimens, or of treatment or prevention of opportunistic infections, or of an HIV eradication strategy using latency-reversing agents or immunotherapy.<\/p>\n<p>Nope &#8212; it&#8217;s a study of cardiovascular prevention with an exotic class of drugs called <em>statins<\/em>.<\/p>\n<p><em>(Sarcasm alert.)<\/em><\/p>\n<p>That&#8217;s right, statins. As noted here <a href=\"https:\/\/blogs.nejm.org\/hiv-id-observations\/index.php\/make-preventing-heart-disease-hiv-fun-exciting\/2017\/02\/13\/\" target=\"_blank\" rel=\"noopener\">several years ago<\/a>, REPRIEVE recruited stable people with HIV age 40 or older, on ART, and at low to moderate risk of cardiovascular disease &#8212; people for whom a statin would generally not be prescribed. Since HIV confers up to a 2-fold increased risk of CVD compared to people without HIV, the hypothesis was that a statin would reduce the risk of a major adverse cardiovascular event compared to placebo.<\/p>\n<p>The drug chosen was pitavastatin, since it doesn&#8217;t interact with any ART regimen. 7769 people enrolled at study sites throughout the world, with diverse demographics and broad geographic representation. It was a &#8220;simple&#8221; (nothing this size is really simple) study design, with randomization to pitavastatin or matching placebo.<\/p>\n<p>After a median follow-up of approximately 5 years, the data and safety monitoring board overseeing the study stopped the study early because of a highly significant benefit of pitavastatin &#8212; the risk reduction for pitavastatin vs. placebo was 35%.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">REPRIEVE:  Significant decrease in major adverse cardiovascular events with pitavastin.<\/p>\n<p>RCT trial enrolled only low-to-moderate CV risk PWH, for whom a statin might not otherwise be prescribed.<\/p>\n<p>Important clinical trial with direct relevance to pt care. <a href=\"https:\/\/t.co\/dVtQgtAGhz\">https:\/\/t.co\/dVtQgtAGhz<\/a> <a href=\"https:\/\/t.co\/eI5ZeOvzcB\">pic.twitter.com\/eI5ZeOvzcB<\/a><\/p>\n<p>&mdash; Paul Sax (@PaulSaxMD) <a href=\"https:\/\/twitter.com\/PaulSaxMD\/status\/1683276511179325442?ref_src=twsrc%5Etfw\">July 24, 2023<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>The benefits of pitavastatin were consistent across baseline demographics and medical issues, with point estimates favoring the intervention over placebo in virtually every group. Overall, this translated to a 5-year number needed to treat (NNT) to prevent a major cardiovascular event of 106 (95% CI, 64 to 303), in line with or better than other widely adopted interventions (treatment of hypertension, or aspirin) to prevent this complication.<\/p>\n<p>Presenting the study results to a packed conference room at the IAS meeting, lead investigator Dr. Steven Grinspoon highlighted several uncertainties that await further study, among them:<\/p>\n<ul>\n<li><em>What is the mechanism of this risk reduction?<\/em> The magnitude was greater than would have been expected solely based on the lipid-lowering effect, implying the anti-inflammatory property of the statin also played a major role.<\/li>\n<li><em>Is the higher incidence of diabetes with statin therapy enough to counter any of these favorable results?<\/em> This risk is in line with what has been observed in other statin studies, though in some regions where diabetes is very common, this could be an issue.<\/li>\n<li><em>Are there certain subgroups likely to have more or less benefit?<\/em> Oddly, people with hypertension did not appear to benefit as much &#8212; probably just a fluke. And we&#8217;ve been tracking certain antiretrovirals with CV risk for many years; it will be fascinating to see if any specific regimens confer excess risk, with or without pitavastatin.<\/li>\n<li><em>How will we interpret absolute vs. relative risk in clinical practice?<\/em> Not surprisingly, those at lowest cardiovascular risk have a higher NNT (200) to benefit one patient. Even if pitavastatin lowers the risk by 35% in this group, does the low absolute risk make it worthwhile to add another drug?<\/li>\n<li><em>Would another statin have comparable results?<\/em> After all, pitavastatin is rarely prescribed today, as generic statins are much less expensive. The drug is also not available in many countries.<\/li>\n<li><em>What was the impact of COVID-19 on outcomes?<\/em> The study started enrolling in 2015, and completed in 2023. That means a lot of participants got COVID-19 during the study, both before and after vaccines became available.<\/li>\n<li><em>Would we get the same result in people without HIV?<\/em> Not saying that REPRIEVE is going to answer this question &#8212; just wondering. The &#8220;put statins in the water&#8221; camp certainly believe this!<\/li>\n<\/ul>\n<p>Numerous substudies are ongoing or planned to try and tease out the answer to these and other questions. As we await them, we can congratulate Steve (whom I&#8217;ve known for years as a thoughtful and collaborative investigator) and his large research team for completing this remarkable study.<\/p>\n<p>We can also again reflect on how far we have come in HIV medicine in making PWH rock-solid healthy, so that non-ID health issues, in particular diseases of aging, dominate their wonderfully long lives. Steve is an endocrinologist; the protocol co-chair (Dr. Pamela Douglas) is a cardiologist. And while there are <a href=\"https:\/\/www.reprievetrial.org\/our-team\/clinical-coordinating-center-ccc\/\" target=\"_blank\" rel=\"noopener\">ID doctors on the leadership team<\/a> (hello Drs. Carl Fitchenbaum and Judy Aberg!), it&#8217;s notable that major advances in HIV research have drifted away from an ID doctor&#8217;s typical areas of focus.<\/p>\n<p>More importantly, a conversation about the risks and benefits of statin use is mainstream general medicine discourse, something that happens thousands if not millions of times a day in primary care. Stable people with HIV are overwhelmingly just that &#8212; stable.<\/p>\n<p>These provider-patient discussions will have nothing to do with complex resistance genotypes, novel antiretroviral drug classes, or life-threatening opportunistic infections. About the most complicated aspect of this discussion from the ID\/HIV standpoint will be the drug interactions if your patient is still on a regimen containing the pharmacokinetic boosters ritonavir or cobicistat, a rapidly dwindling patient group, and you choose to use atorvastatin.<\/p>\n<p>(That&#8217;s easy &#8212; just start with a low dose, 10 milligrams daily.)<\/p>\n<p>Now <em>I<\/em> still enjoy the general medicine that comes with longitudinal HIV follow-up, but I do understand if some ID doctors opt out. And whether these statin yea-or-nay discussions should be in the domain of ID specialists, or general internists, or both, <a href=\"https:\/\/blogs.nejm.org\/hiv-id-observations\/index.php\/what-is-the-future-of-hiv-primary-care\/2023\/04\/28\/\" target=\"_blank\" rel=\"noopener\">is another topic entirely.<\/a><\/p>\n<p>Notably, Australia has never put HIV care in the sole domain of ID specialists. It&#8217;s a model we should look at increasingly over the next years-to-decades, thanks to the success of HIV treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The biggest news this week at the 12th IAS Conference on HIV Science here in Brisbane, Australia, was the results of REPRIEVE, a large randomized clinical trial conducted in people with HIV.
