Nonopportunistic infection leading to rapidly progressive dementia in a patient with HIV/AIDS: A case report

Rationale: Cognitive dysfunction is a common presenting symptom in patients with HIV/AIDS. It is usually directly associated with HIV infection or due to opportunistic infection. Rapidly progressive dementia, however, is rarely observed in acute HIV infection or during immune reconstitution. Recently, a case of Creutzfeld-Jakob disease (CJD) has been reported in a patient with chronic HIV infection. The incidence of CJD is not known to be increased among immunocompromised patients. Patient concerns: We here report the case of a 59-year-old male patient with a recent diagnosis of HIV/AIDS and Pneumocystis jiroveci pneumonia presenting with secondary behavioral changes and disorientation. Over the course of several weeks, progressive dementia developed characterized by apraxia, gait ataxia, and mutism. Diagnoses: After the exclusion of common HIV-associated neurologic conditions, the clinical course as well as findings on electroencephalogram (EEG), magnetic resonance imaging (MRI), and a positive 14-3-3 assay converged into a probable diagnosis of CJD. The diagnosis was later confirmed histopathologically. Outcomes: Palliative care was provided, and the patient passed away within 2 months of symptom onset. Lessons: HIV/AIDS is an important stratifying condition during the work-up of many clinical syndromes including encephalopathy but may prematurely exclude important differential diagnoses. Non-opportunistic etiologies have to be considered as part of a secondar...
