Low CD4 cell count and older age associated with increased risk of TB after starting HIV therapy

By Michael Carter as seen on AIDSmap.com

 

People with HIV reduce their overall risk of tuberculosis (TB) by starting antiretroviral therapy, an international team of investigators report in the online edition of Clinical Infectious Diseases. Despite this, the risk of the disease increased in the first three months of HIV treatment, especially for older people and those with a low CD4 cell count. For severely immunosuppressed people, the risk of TB remained increased in the longer term.

“Physicians should be aware of the potentially increased risk of developing tuberculosis after cART [combination antiretroviral therapy] initiation,” comment the investigators.

The study was conducted because of uncertainty about the level of protection which starting HIV therapy provides against TB.

The immune restoration which accompanies the initiation of antiretroviral treatment should offer protection against the infection. However, it can also be associated with a short-term risk of what is called immune reconstitution inflammatory syndrome (IRIS). This could be because of the paradoxical worsening of previously treated TB, or the ‘unmasking’ of sub-clinical disease. The risk of IRIS is greatest during the first three months of HIV therapy.

Investigators from Europe and the US therefore designed a study involving approximately 65,000 people who received HIV care between 1996 and 2007. All these participants were antiretroviral naive at baseline. The overall risk of TB was compared between individuals who started HIV therapy and those who did not. The risk of the disease was also calculated according to the time since HIV therapy was started and also according to risk factors such as CD4 cell count and age.

During a median of 28 months of follow-up, a total of 712 patients were diagnosed with TB. This provided an overall incidence of three cases per 100 person-years.

Overall, starting HIV therapy was associated with a substantial reduction in the risk of TB (HR = 0.56; 95% CI, 0.44-0.72), leading the investigators to comment: “This study shows a reduction of 44% in tuberculosis incidence among HIV-positive individuals who start cART in high income countries.”

However, incidence of TB differed according to a number of HIV-related and demographic characteristics.

It was highest among people with a CD4 cell count below 50 cells/mm(8.4 cases per 100 person-years) and lowest for those with a CD4 cell count above 500 cells/mm3 (2.1 cases per 100 person-years). This difference is explained by the much higher numerical incidence of TB at lower CD4 cell counts.

Incidence also differed according to HIV risk group. It was lowest among gay and other men who have sex with men (one case per 100 person-years), and highest in people who originated from sub-Saharan Africa (7.7 cases per 100 person-years).This difference is explained by the population burden of latent TB infection and by higher infection rates in sub-Saharan Africa.

Incidence of the infection was lower in younger people compared to older people (under 35 = 2.4 cases per 100 person-years vs over 50 = 4.8 cases per 100 person-years), due in part to a lower duration of potential exposure to TB among younger people,

“Impaired immunological responses to M. tuberculosis in people starting cART at very low CD4 cell counts and those above 50 years of age warrant further investigation,” comment the investigators.

Despite the overall reduction in the risk of TB associated with HIV therapy, the investigators found that people starting treatment actually had an increased risk of the disease during the first three months of treatment compared to those who remained antiretroviral naive (HR = 1.36; 95% CI, 0.98-1.89).

HIV therapy lasting longer than three months was associated with a 56% reduction in the risk of TB (HR = 0.44; 95% CI, 0.34-0.58).

“The epidemiological pattern suggests that unmasking IRIS may be playing a role,” write the authors.

But even after three months of therapy, people with a CD4 cell count below 50 cells/mm3 were still more likely to develop TB than those who had not started antiretroviral treatment (HR = 1.02; 95% CI, 0.44-2.36).

“These patients remain in a state of relevant immunodeficiency in spite of cART for longer periods and are therefore at higher risk of reactivating latent tuberculosis beyond 3 months after starting cART,” suggest the investigators. “Further follow-up of these cohorts will show whether the risk of tuberculosis does eventually drop with longer exposure to cART.”

The role of IRIS in TB risk was further suggested by the overall reduction in the incidence and risk of PCP (Pneumocystis jirovecii pneumonia) that accompanied the initiation of antiretroviral treatment in both the short and long term.

The authors conclude: “For cART to be useful in tuberculosis control, prompt HIV infection testing is needed so cART can be started when clinically indicated rather than at advanced immunodeficiency. Diagnosis and treatment of M. tuberculosis infection, as national and international guidelines recommend, should be reinforced. Even in countries with low tuberculosis transmission, intensified case finding remains essential.”

Immune-Correlates Analysis of an HIV-1 Vaccine Efficacy Trial

HIV Vaccine Study Offers Up Possible Antibody Protection Clues

Scientists continued to unravel clues as to why a combination of two preventive HIV vaccines—ALVAC HIV and AIDSVAX B/E—may have worked for some but not others in a large scale clinical trial reported in 2009. A new paper (see below) published online ahead of print in The New England Journal of Medicine (NEJM) suggests those who produced relatively high levels of a specific antibody after receiving the vaccinations in study RV 144 were less likely to become infected with HIV, compared with those who did not.

Immune-Correlates Analysis of an HIV-1 Vaccine Efficacy Trial

As seen in The New England Journal of Medicine 

BACKGROUND

In the RV144 trial, the estimated efficacy of a vaccine regimen against human immunodeficiency virus type 1 (HIV-1) was 31.2%. We performed a case–control analysis to identify antibody and cellular immune correlates of infection risk.

METHODS

In pilot studies conducted with RV144 blood samples, 17 antibody or cellular assays met prespecified criteria, of which 6 were chosen for primary analysis to determine the roles of T-cell, IgG antibody, and IgA antibody responses in the modulation of infection risk. Assays were performed on samples from 41 vaccinees who became infected and 205 uninfected vaccinees, obtained 2 weeks after final immunization, to evaluate whether immune-response variables predicted HIV-1 infection through 42 months of follow-up.

RESULTS

Of six primary variables, two correlated significantly with infection risk: the binding of IgG antibodies to variable regions 1 and 2 (V1V2) of HIV-1 envelope proteins (Env) correlated inversely with the rate of HIV-1 infection (estimated odds ratio, 0.57 per 1-SD increase; P=0.02; q=0.08), and the binding of plasma IgA antibodies to Env correlated directly with the rate of infection (estimated odds ratio, 1.54 per 1-SD increase; P=0.03; q=0.08). Neither low levels of V1V2 antibodies nor high levels of Env-specific IgA antibodies were associated with higher rates of infection than were found in the placebo group. Secondary analyses suggested that Env-specific IgA antibodies may mitigate the effects of potentially protective antibodies.

CONCLUSIONS

This immune-correlates study generated the hypotheses that V1V2 antibodies may have contributed to protection against HIV-1 infection, whereas high levels of Env-specific IgA antibodies may have mitigated the effects of protective antibodies. Vaccines that are designed to induce higher levels of V1V2 antibodies and lower levels of Env-specific IgA antibodies than are induced by the RV144 vaccine may have improved efficacy against HIV-1 infection.

The Odyssey of Therapeutic Vaccines for HIV


The Odyssey of Therapeutic

Vaccines for HIV

tagline Spring 2012

by Richard Jefferys

In the earliest days after the discovery of HIV in the mid-1980s, uncertainty reigned regarding how the immune system responded to the virus. Initially, it was thought that the time between HIV infection and the development of severe immuno- deficiency and disease represented a period of viral inactivity or latency. In this context, it seemed logical to propose that perhaps vaccination could be used to bolster immune response to HIV and thus delay or even prevent the development of illness. But the first efforts toward this goal quickly mired therapeutic vaccine research in controversy, casting an initial pall across the field that was compounded by the failure of any candidate to show significant efficacy. Additionally, the scientific rationale for the approach evolved as more was learned about the pathogenesis of HIV infection and the types of immune responses that may be effective—and ineffective—at controlling the virus. After a period in which enthusiasm regarding the prospects for therapeutic vaccines waned, the recent resurgence in interest in research aiming to cure HIV infection has offered new reasons to pursue their development.

Toward a Cure: The Potential of Therapeutic Vaccines

by Tim Horn at AIDSmeds.com

While gene therapies that render the immune system impervious to HIV and drugs that potentially purge the virus from resting CD4 cells continue to be watched closely by AIDS cure researchers and advocates, therapeutic vaccines may serve an important supporting role in these efforts, according to a commentarypublished by activist Richard Jefferys in the Spring 2012 TAGline newsletter.

“After a period in which enthusiasm regarding the prospects for therapeutic vaccines waned,” Jefferys writes, “the recent resurgence in interest in research aiming to cure HIV infection has offered new reasons to pursue their development.”

Notable therapeutic vaccines for the virus use HIV particles, sometimes paired with other viruses, or largely intact HIV, to jumpstart the immune system’s perceived ability to control viral replication in the body. Such vaccines have been conceptualized and explored since the mid-1980s. “But the first efforts toward this goal quickly mired therapeutic vaccine research in controversy,” Jefferys writes, “casting an initial pall across the field that was compounded by the failure of any candidate to show significant efficacy.”

Jefferys explains that therapeutic vaccines are now in their third—and potentially most critical—era of development, noting that the first two eras didn’t pan out for important reasons.

In the first era, dating back to the 1980s and early 1990s, therapeutic vaccine candidates of the day faced significant hurdles that were unknown at the time. For example, it was once assumed that HIV is mostly dormant during the asymptomatic and untreated years of infection and that CD4 cells lacked the ability to respond to HIV. Subesequent findings proving these hypotheses wrong, Jefferys writes, “seriously called into question the idea that adding more HIV antigens into the mix via therapeutic vaccination—when the virus itself was failing to induce protective immunity—would be beneficial.”

In the second era, with viral load technology and combination antiretroviral therapy (ART) widely available, therapeutic vaccination plans evolved. One approach was to bolster the immune response to HIV while study volunteers were keeping their viral loads undetectable using available ARVs, followed by treatment interruptions to test the immune system’s ability to control HIV replication in the absence of therapy.
