A 66-year-old patient presents with bilateral otitis media with effusion and white patches in the mouth. What should the patient be evaluated for?

The presence of bilateral otitis media with effusion along with white patches in the mouth raises a concern for possible underlying immunosuppression or infection. Evaluating for HIV infection is particularly pertinent in this context, as the combination of these symptoms can suggest opportunistic infections or conditions associated with immunocompromised states. Specifically, oral lesions such as white patches could represent oral candidiasis, a common manifestation in individuals with weakened immune systems, including those with HIV/AIDS.

In older adults, it is important to consider signs that may indicate a compromised immune system, and the patient's age coupled with the presented symptoms point towards the need for an evaluation for HIV. This assessment can guide further management and treatment to ensure comprehensive care for the patient.
