Re: Infectious mononucleosis

Lennon et al’s clinical review of infectious mononucleosis recommends considering HIV testing in “high risk” groups, which they define as injecting drug users and men who have sex with men.[1] We disagree with this restricted indication.

The identification of risk factors for HIV infection is notoriously unreliable as a screening tool for deciding when to offer a test[2], In the HIDES 2 study, patients at 42 European centres that presented with mononucleosis were routinely offered an HIV test and 5.3% had undiagnosed HIV.[3] In London, primary care requests for a glandular fever screen underwent anonymous blinded testing for HIV and the prevalence was 1.3% (95% confidence interval 0.7 to 2.3%); 73% of the diagnoses had been missed at the primary care consultation.[4] Mathematical models estimate that it is cost-effective to test widely where the prevalence of undiagnosed HIV infection exceeds 0.1%.[5-7] In the United Kingdom, an estimated 107,800 people are currently living with HIV, of whom 24% have not been diagnosed.[8] European and national specialist societies concur that HIV testing should be offered to all patients with a mononucleosis-like syndrome[9,10]

Mononucleosis is clinically indistinguishable from acute (primary) HIV infection, and this represents an excellent opportunity for early HIV diagnosis. In the United Kingdom, patients who are diagnosed with HIV at an early stage (defined as a CD4 count of greater than 350 cells/mm3) have a life expectancy that is equal to the general population.[11] By contrast, late diagnosis is associated with opportunistic disease, markedly increased healthcare costs, and an increased risk of death.[12-13]

We believe that all patients presenting in any healthcare setting with a mononucleosis syndrome, regardless of identifiable risk factors, should be offered an HIV test. Furthermore, HIV testing should be routinely included in a glandular fever screening panel with an opt-out strategy for consent in view of the prevalence of undiagnosed HIV in patients with mononucleosis. Any healthcare professional should be competent to offer a test[9] and opportunities to diagnose the infection should not be missed.
