Pediatric Neurology in Resource-Limited Settings: a Systematic Review

Improving epilepsy control among children with cerebral palsy in rural Bangladesh: a prospective cohort-based study

OBJECTIVE

To define the prevalence and seizure subtypes among children with cerebral palsy (CP) in rural Bangladesh and explore barriers to optimum epilepsy control.

DESIGN

Prospective cohort study.

SETTING

The study was conducted in Shahjadpur, a rural subdistrict of Bangladesh.

PARTICIPANTS

Children (<18 years) with CP and epilepsy identified using the Bangladesh CP Register (BCPR) in the study site.

METHODS

Assessments were conducted in three focused epilepsy clinics overseen by a paediatric neurologist between December 2016 and January 2018, with intervening phone and video-conference follow-ups. Details of event type, frequency and medication compliance were collected. Antiepileptic drugs (AEDs) were prescribed based on seizure type, family income, comorbidity and medication availability.

RESULTS

23.4% (170/726) of the BCPR cohort had a clinical diagnosis of epilepsy of whom 166 were assessed. Following the focused epilepsy clinics, 62.0% (103/166) children were clinically determined to have ongoing epileptic seizures. 62.1% (64/103) had generalised onset tonic clonic seizures, 27.2% (28/103) had focal onset seizures with impaired awareness and 10.7% (11/103) had other seizure types. None of the children with prolonged seizures (31/103) had an emergency seizure management plan. Non-epileptic events were being pharmacologically treated as seizures in 18.1% (30/166) children. Financial constraints were the main reason for non-compliance on follow-up.

CONCLUSIONS

Gaps in optimum epilepsy management in rural Bangladesh are amenable to improvement anchored with local healthcare workers. Training and clinical care focused on recognition of common seizure types, seizure mimics and rationalising use of available AEDs can be facilitated by better referral pathways and telehealth support.

Infantile spasms: Etiology, lead time and treatment response in a resource limited setting

•

Neonatal hypoglycemic brain injury was the commonest cause of Infantile Spasms (IS).

•

Comprehensive genetic evaluation was performed in presumed genetic IS patients.

•

Molecular diagnosis was achieved in 44% of presumed genetic patients.

•

Longer lead time to treatment was significantly associated with resistant spasms.

This study explores the etiology and lead time to treatment for infantile spasm (IS) patients and their effect on treatment responsiveness, in a limited resource setting. Patients with IS onset age ≤12 months’, seen over 3 years were recruited retrospectively. Clinical information, neuroimaging and genetic results retrieved. Patients categorized into three primary etiological groups: Structural (including Structural Genetic), Genetic, and Unknown. The effect of etiology and lead time from IS onset to initiating appropriate treatment on spasm resolution, evaluated. Total 113 patients were eligible. Mean IS onset age was 6.86(±4.25) months (M: F 3.3:1). Patients were grouped into: Structural 85, Genetic 11 and Unknown 17. Etiology was ascertained in 94/113 (83.1%) with neonatal hypoglycemic brain injury (NHBI) being the most common (40/113, 36%). A genetic etiology identified in 17 (including 6 Structural Genetic, of which five had Tuberous Sclerosis). Structural group was less likely to be treatment resistant (p = 0.013, OR 0.30 [0.12–0.76]). Median treatment lead time – 60 days. Longer lead time to treatment was significantly associated with resistant spasms (χ² for trend = 10.0, p = 0.0015). NHBI was the commonest underlying cause of IS. There was significant time lag to initiating appropriate treatment, affecting treatment responsiveness.
