A patient is attending an HIV/AIDS clinic following an HIV test performed last month by the HCP

QUESTION

A patient is attending an HIV/AIDS clinic following an HIV test performed last month by the HCP. The patient initially presented to the HCP with oral thrush which was treated with oral nystatin. Since this infection is uncommon in adulthood, the HCP arranged for an HIV ELISA screening test followed by a western blot test to confirm the diagnosis. The patient has multiple risk factors for acquiring this viral infection including IV drug use, multiple sexual partners and not using condoms. The client recalls having a “bad cold and sore throat” around 3 years ago, but it resolved spontaneously without any treatment. Which CD4 count would be associated with a diagnosis of AIDS? Following a potential exposure to HIV, post-exposure prophylaxis should be started within… Following a potential exposure to HIV, post-exposure prophylaxis should be started within… 28 days 72 hours 6 months 7 days In which of the following patients would lopinavir/ritonavir be contraindicated? In which of the following patients would lopinavir/ritonavir be contraindicated? A patient with hypothyroidism. A patient with Crohn’s disease A patient with kidney disease A patient with severe heart failure

ANSWER

CD4 Count Associated with a Diagnosis of AIDS

In the context of HIV infection, a diagnosis of AIDS (Acquired Immunodeficiency Syndrome) is typically made when the CD4 (T-cell) count falls below 200 cells/mm³ or when certain AIDS-defining illnesses or conditions occur, regardless of CD4 count. These AIDS-defining illnesses include opportunistic infections and certain cancers.

However, it’s important to note that CD4 counts alone do not determine the progression to AIDS; the presence of specific clinical conditions or infections is equally important. In this case, the patient’s history of oral thrush and risk factors for HIV suggest that they may be at an advanced stage of HIV infection. Therefore, a CD4 count below 200 cells/mm³ would be associated with a diagnosis of AIDS for this patient.

Post-Exposure Prophylaxis (PEP) for HIV

Following a potential exposure to HIV, PEP should be initiated as soon as possible, ideally within 72 hours (3 days) of the exposure. PEP is most effective when started early, and initiating it within 72 hours significantly reduces the risk of HIV transmission. Therefore, the correct option is:

72 hours

Contraindications for Lopinavir/Ritonavir

Lopinavir/Ritonavir is a combination medication used in the treatment of HIV infection. It is essential to consider contraindications and potential drug interactions when prescribing this medication. In this case, the patient with severe heart failure would be contraindicated for Lopinavir/Ritonavir.

D. A patient with severe heart failure

Lopinavir/Ritonavir can have interactions with certain medications and may have cardiovascular side effects. Patients with severe heart failure may be at higher risk of experiencing adverse cardiovascular effects, and the medication should be used with caution or avoided in such cases. It is crucial for healthcare providers to assess each patient’s medical history and potential drug interactions before prescribing antiretroviral medications for HIV treatment.
