A human immunodeficiency virus-seronegative acquired immunodeficiency syndrome patient with opportunistic infections: A case report

Abstract

Background

In rare cases, people living with chronic human immunodeficiency virus (HIV) infection do not develop antibodies despite demonstrable infection. Delayed or missed diagnosis of HIV infection leads to a lack of timely therapy, resulting in rapid disease progression with opportunistic infections or malignancies.

Case Report

A 44-year-old Chinese man presented with sore throat, oral leukoplakia, fever, dyspnoea and diffuse ground glass-like lesions in both lungs. Serum cytomegalovirus DNA was detectable, and CD4⁺ T-cell count was low. The patient was suspected of being a person living with HIV despite of the repeatedly negative HIV antibody tests using enzyme-linked immunsorbent assay and Western blot. Subsequently, high-plasma HIV RNA viral load was found on two repeated tests, while HIV DNA was also positive. Thus, the patient was confirmed as presenting with HIV-seronegative acquired immunodeficiency syndrome (AIDS). The symptoms improved in response to effective anti-fungal and anti-retroviral therapy after diagnosis.

Conclusion

This is the third reported case of an HIV-seronegative AIDS patient in China, which are also rarely reported globally. HIV nucleic acid testing is important to screen out HIV infection, especially in those who present with severe immunodeficiency but remain HIV serogenative.
