Sir,

Progressive multifocal leukoencephalopathy (PML) is a rare opportunistic infection of the central nervous system caused by John Cunningham virus (JCV). PML frequently occurs in patients with acquired immunodeficiency syndrome, but it is rarely seen in idiopathic CD4 + lymphocytopenia.[1]

A 39 years old male was hospitalized with a new onset seizure. No chronic illnesses were noted. He had a weight loss of 20 kg in the last 6 months. He was alert, orientation was limited, and had difficulty in word finding. On follow up, there were recurrent generalized tonic clonic seizures. EEG showed left frontal 4–6 Hz slow waves. 1000 mg/day valproic acid was started. Patients' CD4 cell count was 446 cells/mm3, and HIV plasma viral load was 42800 copies/mL. CSF analysis showed protein 431 mg/dL, 30 leukocytes/mm3. CSF cultures and cryptococal antigen were negative. Ebstein Barr, herpes simplex 1-2, varicella zoster, cytomegalovirus were not detected by PCR. JCV- PCR was positive in CSF (2680 copies/mL).

Cranial magnetic resonance imaging (MRI) revealed hyperintensity in left frontoparietal on the T2, diffusion-weighted and FLAIR images revealed hyperintense lesion [Figure 1]. The patient was diagnosed with AIDS-related PML.{Figure 1}

Highly active antiretroviral treatment (HAART) and mirtazapine were initiated. Mirtazapine inhibits 5-hydroxytryptamine-2a serotonin receptor for JCV entry CNS.[2] On the fourth week of the HAART, HIV plasma viral load decreased to 48 copies/mL, CD4 cell count increased to 123 cells/mm3. Patient had right hemiparesia and motor aphasia. MRI showed the lesion had spread to neighboring regions [Figure 2]. Paradoxal immunologic reconstruction inflammatory response (IRIS) was diagnosed. In total, 1 g/day methylprednisolone was started. The oral taper was continued. Hemiparesia significantly improved. Two months later, he interrupted the treatment with his own will then HIV plasma viral load increased; CD4 cell count decreased. He had hemiplegia and mix aphasia. There was deterioration on MRI findings [Figure 3].{Figure 2}{Figure 3}

The first manifestation was an epileptic seizure related to PML underlying reason of HIV infection in our patient. Kim HK, et al.[3] reported two patients had experienced seizures as a presenting manifestation of the HIV-associated PML.

Nearly one-third of the HIV-infected patients with PML developed paradoxal IRIS after HAART. Low CD4 count and rapid immune recovery by prompt decrease in HIV plasma viral load were predictive factors development of the IRIS.[4] So our case was in high-risk group.

This case was found informative because AIDS-related PML diagnosed during the course of the new onset epileptic seizures and management of paradoxical IRIS.
