HIV and the Brain in Hyderabad: From Subtle Cognitive Slowing to Cryptococcal Meningitis — Every Stage Has a Specific Management Plan at KIMS

Yes — and this is an important reality that is under-recognised. HAND (HIV-Associated Neurocognitive Disorders) affects approximately 30–50% of people living with HIV, even those with well-controlled viral loads on effective ART. HIV enters the brain early in infection, before treatment starts, and establishes persistent viral reservoirs in brain macrophages. Ongoing neuroinflammation from prior high viral loads, direct HIV neurotoxicity, and the ageing process all contribute. The most common symptoms: slowed thinking, difficulty concentrating, forgetting things more than before, taking longer to complete familiar tasks, and mood changes. These are real neurological symptoms, not just stress. At KIMS, a formal neuropsychological assessment identifies which cognitive domains are affected and guides management, which includes ART regimen review for CNS penetration. Call 040-44885000.

Call 040-46324365 immediately. A CD4 count of 50 with new headache and confusion is cryptococcal meningitis until proven otherwise. At this CD4 level, Cryptococcus neoformans — a fungus — can infect the brain and spinal cord covering, causing meningitis that is uniformly fatal without treatment. Time matters: every hour without antifungal therapy (liposomal amphotericin B) is time during which the fungus continues to replicate in the CSF and brain tissue. The emergency number at KIMS is 040-46324365. Do not wait.

Ring-enhancing brain lesions in an HIV-positive patient most commonly have two causes: toxoplasma encephalitis (reactivation of prior Toxoplasma gondii infection when immunity falls) and primary CNS lymphoma (EBV-driven B-cell lymphoma at very low CD4). The approach at KIMS: first, check toxoplasma IgG serology — if positive and CD4 is below 100–200, start empirical treatment (pyrimethamine + sulfadiazine + folinic acid) immediately without brain biopsy. Reassess with MRI at 2 weeks: if the lesions have reduced significantly, toxoplasma is confirmed and treatment continues. If the lesions are unchanged or worsening at 2 weeks, CNS lymphoma is more likely — CSF EBV PCR and brain biopsy are then arranged. Most patients can be diagnosed and treated without biopsy using this approach. Call 040-44885000.

Not yet — and this is a critical safety point. Fluconazole maintenance (200mg daily) for cryptococcal meningitis should be continued until CD4 is consistently above 200 cells/mm³ for at least 6 months on a suppressive ART regimen. With your CD4 at 350, you may be approaching the threshold, but both criteria — CD4 above 200 AND 6 months above that level — need to be met before fluconazole can be safely stopped. Premature discontinuation carries a significant risk of cryptococcal relapse, which can be more difficult to treat than the original infection. At KIMS, we arrange a specific review appointment to assess fluconazole discontinuation eligibility. Please call 040-44885000 to book this review.

Several strategies are available at KIMS for HAND on suppressive ART. First, ART regimen review: your current regimen is assessed for CNS Penetration Effectiveness (CPE) — if the score is low, switching to a higher CPE regimen may improve cognitive symptoms over months. Second, investigation for contributing factors: depression (which is extremely common in PLHIV and profoundly amplifies cognitive symptoms), sleep disorders, anaemia, thyroid dysfunction, vitamin B12 deficiency, and hepatitis C co-infection — all are identified and treated at KIMS. Third, neuropsychological assessment and rehabilitation: specific cognitive strategies for memory and attention, occupational therapy, and structured cognitive training. Fourth, treatment of depression: SSRIs (sertraline, escitalopram) or SNRIs are effective and important for PLHIV with depression. Call 040-44885000.
