CHICAGO -- John Holloway received a diagnosis of AIDS nearly two decades ago, when the disease was a speedy death sentence and treatment a distant dream.
Yet at 59 he is alive, thanks to a cocktail of drugs that changed the course of an epidemic. But with longevity has come a host of unexpected medical conditions, which challenge the prevailing view of AIDS as a manageable, chronic disease.
Mr. Holloway, who lives in a housing complex designed for the frail elderly, suffers from complex health problems usually associated with advanced age: chronic obstructive pulmonary disease, diabetes, kidney failure, a bleeding ulcer, severe depression, rectal cancer and the lingering effects of a broken hip.
Those illnesses, more severe than his 84-year-old father’s, are not what Mr. Holloway expected when lifesaving antiretroviral drugs became the standard of care in the mid-1990s.
The drugs gave Mr. Holloway back his future. But at what cost?
That is the question, heretical to some, that is now being voiced by scientists, doctors and patients encountering a constellation of ailments showing up prematurely or in disproportionate numbers among the first wave of AIDS survivors to reach late middle age.
The graying of the AIDS epidemic has increased interest in the connection between AIDS and cardiovascular disease, certain cancers, diabetes, osteoporosis and depression. The number of people 50 and older living with H.I.V., the virus that causes AIDS, has increased 77 percent from 2001 to 2005, according to the federal Centers for Disease Control, and they now represent more than a quarter of all cases in the United States.
The most comprehensive research has come from the AIDS Community Research Initiative of America, which has studied 1,000 long-term survivors in New York City, and the Multi-Site AIDS Cohort Study, financed by the National Institutes of Health, which has followed 2,000 subjects nationwide for the past 25 years.
The Acria study, published in 2006, examined psychological, not medical, issues and found unusual rates of depression and isolation among older people with AIDS.
The Multi-Site AIDS Cohort Study, or MACS, will directly examine the intersection of AIDS and aging over the next five years. Dr. John Phair, a principal investigator for the study, which has health data from both infected and uninfected men, said “prolonged survival” coupled with the “naturally occurring health issues” of old age raised pressing research questions: “Which health issues are a direct result of aging, which are a direct result of H.I.V. and what role do H.I.V. meds play?” The MACS investigators, and other researchers, defend the slow pace of research as a function of numbers. The first generation of AIDS patients, in the mid-1980s, had no effective treatments for a decade, and died in overwhelming numbers, leaving few survivors to study.
There are no data that compare the incidence, age of onset and cause of geriatric diseases in the general population with the long-term survivors of H.I.V. infection. But physicians and researchers say that they do not see people in their mid-50s, absent AIDS, with hip replacements associated with vascular necrosis, heart disease or diabetes related to lipodystrophy, or osteoporosis without the usual risk factors.
“All we can do right now is make inferences from thing to thing to thing,” said Dr. Tom Barrett, medical director of Howard Brown. “They might have gotten some of these diseases anyway. But the rates and the timing, and the association with certain drugs, makes everyone feel this is a different problem.”
One theory about why research on AIDS and aging has barely begun is “the rapid increase in numbers,” Dr. Emlet said. The federal disease centers’ most recent surveillance data, from 33 states that meet certain reporting criteria, showed that the number of people 50 and older with AIDS or H.I.V. infection was 115,871 in 2005, nearly double the 64,445 in 2001.
Another is the routine exclusion of older people from drug trials by big pharmaceutical companies. The studies are designed to measure safety and efficacy but generally not long-term side effects.
Those explanations do not satisfy Larry Kramer, founder of several AIDS advocacy groups. Mr. Kramer, 73 and a long-term survivor, said he had always suspected “it was only a matter of time before stuff like this happened” given the potency of the antiretroviral drugs. “How long will the human body be able to tolerate that constant bombardment?” he asked. “Well, we are now seeing that many bodies can’t. Once again, just as we thought we were out of the woods, sort of, we have good reason again to be really scared.”
The lack of research also limits a patient’s care. Dr. Barrett says the incidence of osteoporosis warrants routine screening. Medicare, Medicaid and private insurers, however, will not cover bone density tests for middle aged men.
