As Summer Peaks, the US House of Representative Appropriations Committee Proposes Budget that Keeps Fogarty International Center Intact
 
Gretchen L. Birbeck, MD, MPH, Without Borders Editor, Rochester, NY
 
Most in the ‘global know’ were dumbfounded in March when both President Trump’s “skinny” budget and the subsequent detailed one explicitly targeted the Fogarty International Center (FIC) for closure.1 Happy news arrived earlier this month when the appropriations committee for the House of Representatives approved a bill that did not close Fogarty but in fact allocated FIC a 1.5% increase ($73.4 million total budget).2 Despite its teeny, tiny budget (described by some as amounting to “less than pencil dust” in the overall NIH budget, Fogarty’s work yields serious benefits to U.S citizens and the global community alike including Fogarty’s leadership in the Brain Disorders programme which has played such a central role in the globalization of US Neurology.3 A disclosure—as an investigator funded through the Brain Disorders program and a Fogarty International Center Advisory Board member, I am seriously conflicted here. So don’t take my word for it—you can read any number of Op Eds and commentaries testifying to the critical nature of the FIC.1, 4-6 The Senate appropriations committee take this up in September. We certainly live in interesting times. Stay tuned.

Humanitarian crises and the use of teleneurology
 
Gretchen L. Birbeck, MD, MPH, Without Borders Editor, Rochester, NY
 
For an interesting read, check out this report on Teleneurology from Saadi and Mateen detailing neurology referrals from Doctors without Borders delivered via a Collegium Telemedicus platform. As is so often the case with relatively new healthcare services, the report raises as many questions as it answers. If anyone reading this has utilized this system for MSF neurology consultation requests, it would be fascinating to better understand what the barriers are to referral given the relatively low numbers received. So few referrals were requested, I was reminded of the Peanuts cartoon with Lucy sitting all alone in her consultation booth awaiting the opportunity to give Psychiatry consultations for ¢5. Having provided these asynchronous telemedicine consultations myself, I must say my comfort level when offering advice to physicians located in regions where I have professional experience working and am very familiar with local clinical epidemiology, disease burden and health services capacity is quite high. In contrast, I am frankly uncomfortable when asked for my opinion on cases from regions where I lack these basic insights.

Acute symptomatic seizures in the tropics—The need to improve outcomes
 
Gretchen L. Birbeck, MD, MPH, Without Borders Editor, Rochester, NY
 
Regarding1 acute symptomatic seizure associated with tropical conditions such as cerebral malaria2 and Japanese encephalitis virus3 as being well-recognized to frequently result in neurologic sequelae including epilepsy, neurodevelopmental abnormalities and behavioral disorders, in the June issue of Seizure, Soni et al1 working in Chandigarh, India detail neurologic outcomes in a cohort of 604 children with acute symptomatic seizures due to a number of conditions. The acute mortality rate was 1% and all those who died had seizures as a result of CNS infections. Neurodevelopmental disabilities were seen in 16% and risk factors for this included requiring more than one antiepileptic drug during the index admission, sequelae at discharge, abnormal neuroimaging and an abnormal EEG. Even in the relatively short 6-month follow-up period, almost 6% of survivors developed epilepsy following their acute symptomatic seizure with risk factors for epilepsy development including CNS infection as the etiology for the index seizures, presenting with status epilepticus, abnormal EEG findings and abnormal imaging. Longer term outcomes and behavioral outcomes were not available. Unlike in the US with viral gastroenteritis is the commonest precursor of acute symptomatic seizures in children, in this region of India and many other tropical regions CNS infections predominate. NIH-funded clinical trials aimed at identifying targets for neuroprotection from cerebral malaria sequelae are underway now (NCT01660672; NCT01982812; NIHR01NS102176). Given the similarities in the incidence and type of sequelae seen in this larger India-based cohort, if neuroprotective trials for malaria are successful, expansion to this more heterogenous group might be warranted.

International AIDS Society 2017 Conference Report

Omar K. Siddiqi, MD, Beth Israel Deaconess Medical Center, Boston 

Siddiqi_2017

The Conference on Retroviruses and Opportunistic Infections (CROI) is an annual scientific meeting devoted to the science The International AIDS Society Conference on HIV Science was held in Paris, France from the 23-26 of July. As a first-time attendee of the conference, I was struck at how almost every lecture provided some take home lessons on global health in general, reinforcing the idea that HIV helped to invent the field of global health. There was no shortage of topics that touched on neurological issues of HIV.

Dolutegravir is an integrase inhibitor that has started to be scaled up as a first line treatment option in all settings because of its shorter duration to viral suppression, lower risk of drug resistance, and favorable side effect profile. The main side effect mentioned in multiple sessions was CNS in nature, specifically chronic insomnia and sleep disturbances. The overall CNS complaints are still less in comparison to Efavirenz. In addition, there are important interactions between Dolutegravir and the most commonly used anti-epileptics in resource limited settings (RLS), phenobarbital and carbamazepine. Carbamazepine and phenobarbital may increase metabolism of Dolutegravir resulting in decreased serum levels. The suggestion is to avoid this combination, if possible, or potentially increase the baseline dose of Dolutegravir. This has important implications for HIV patients with co-morbid epilepsy.

Results were presented from the ACTA trial--a randomized controlled, non-inferiority trial from 9 centers in Malawi, Zambia, Cameroon, and Tanzania for patients presenting with their first episode of cryptococcal meningitis. The aim of the trial was to see if alternatives to two weeks of IV amphotericin B (AmB) were feasible given its lack of availability and difficulty of administration in RLS. Participants were randomized to:

1) oral regimen of high dose fluconazole (1200mg/day) plus flucytosine (100mg/kg/day) for 14 days.
2) one week regimen of IV AmB (1mg/kg/d) plus high dose fluconazole followed by 7 days of high dose fluconazole.
3) one week regimen of IV AmB plus flucytosine, followed by 7 days of high dose fluconazole.
4) IV AmB plus high dose fluconazole for 14 days.
5) IV AmB plus flucytosine for 14 days (gold standard).

The outcome measured was 2 and 10 week mortality. The most interesting findings were that short course 1 wk AmB-based therapy and the exclusively oral regimen or high dose fluconazole/flucytosine were non-inferior to 2wks AmB-based therapy. In addition, 1 wk AmB + flucytosine was associated with better survival compared with all other arms. This study indicates the urgent need to make flucytosine widely available in sub-Saharan Africa where it is currently not registered in the majority of countries.

Dr. Felicia Chow, Assistant Professor of Neurology at UCSF, had an oral presentation “Higher HDL, better brain? Higher HDL is associated with better cognition in a cohort of older persons living with HIV infection”. Her group looked at data from 988 patients from a prospective cohort of older patients in the AIDS Clinical Trials Group A5322 study looking an association between cardiovascular risk and performance on a brief neurocognitive screen. In a multivariate regression analysis, her group demonstrated that longer ART duration and HDL was associated with better cognition in an older cohort of HIV patients. The study suggests that modifying HDL cholesterol may be one way of improving cognitive outcomes in older HIV patients.

Finally, there was a lot of time dedicated to the idea of differentiated care meaning a patient-centered approach to adapt HIV care based on where a patient falls in the treatment cascade. For example, the approach to children, adolescents, pregnant women, and adult males should be different rather than one size fits all. One interesting model of differentiated care is ART adherence clubs. It reduces the burden that stable patients place on healthcare facilities, increasing available clinical human resources for new patients and those clinically unstable who are at risk of failing treatment. In the model, 30 patients are allocated to an ART club. The group meets either at a facility or community venue for less than an hour every 2 months. Group meetings are facilitated by a lay club facilitator who provides a quick clinical assessment, referral when necessary, and dispenses pre-packed ART.1 I immediately thought this model could apply to well controlled epilepsy patients in RLS. I have a large group of stable epilepsy patients who wait hour and hours in my clinic just to get a medication refill. I think the adherence club model would lend itself well to this group. There are countless lessons from HIV care that can improve neurological services in RLS.

Conference Report from the Conference on Retroviruses and Opportunistic Infections

David Bearden, MD, Assistant Professor of Neurology and Pediatrics, Rochester, NY -- USA, MD, PhD 

The Conference on Retroviruses and Opportunistic Infections (CROI) is an annual scientific meeting devoted to the science around the pathophysiology, prevention, and treatment of Human Immunodeficiency Virus (HIV) and opportunistic infections in patients living with HIV. Given that patients with HIV are living longer and are less likely to develop opportunistic infections, there has been growing interest in non-communicable disorders associated with HIV, such as HIV-associated Neurocognitive Disorders (HAND) and HIV-associated stroke. This year at CROI (held February 13-16 in Seattle), the primary emphasis was on the possibility of HIV cure, but there were a number of interesting presentations related to CNS complications of HIV. There were several epidemiologic studies demonstrating that cognitive complications of HIV remain a major issue, even in the era of combined antiretroviral therapy (cART). In IMPAACT P1104s, longitudinal neurocognitive testing was performed in cART-treated children with HIV ages 5-11 in 6 countries in Sub-Saharan Africa. Children with HIV demonstrated significantly worse neurocognitive performance compared to controls, and longitudinal testing demonstrated that these differences persisted or worsened over time. One exciting aspect of CROI this year was that we are beginning to see results from treatment studies. For example, The SABES study randomized patients with very early HIV infection to immediate vs. deferred treatment, and found significant improvements in cognition with early treatment. There were also two interesting studies presented looking at a treatment intensification strategy for treatment of HAND. The first, using the CCR5 antagonist maraviroc, failed to meet the primary endpoint of decreased CSF inflammatory markers, but did show a statistically significant improvement in executive function. The second trial, using the novel CCR5/CCR2 antagonist cenicriviroc, demonstrated a significant improvement in global cognitive function as well as a decrease in CSF inflammatory markers. Both studies were small, open label, uncontrolled trials, and so should be viewed with some skepticism, but treatment intensification appears to be a promising strategy for treatment of cognitive complications of HIV
