Background: Epilepsy is one of the commonest neurological conditions affecting women of reproductive age. Epilepsy management during pregnancy is a clinical conundrum, requiring a balance between seizure control and risk minimization for the women with epilepsy (WWE) as well as for their fetuses. The objective of this comprehensive review is to explore the reproductive health challenges of WWE in sub-Saharan Africa (SSA) and ways to address them. Method: Relevant documentation published until June 2019 were retrieved via literature searches performed in PubMed and Google Scholar, as well as a manual search to identify grey literature. Results: WWE in SSA are generally more stigmatized and sexually exploited than women without epilepsy. Contraception use among WWE was reported only in Senegal (51%) and Kenya (14.7%). Only two prospective studies (one in Senegal and one in Nigeria) investigated pregnancy outcomes for a total of 97 WWE. The prevalence of convulsive epilepsy in pregnancy was estimated at 3.33 per 1000. Among pregnant WWE treated with first line anti-epileptic drugs, 16.2% had miscarriages, 41.9% premature births, and 4.1% had babies with malformations. Carbamazepine, which is frequently prescribed to pregnant WWE in SSA, still entails a 2.1-fold increased risk of congenital malformation. No reports were found concerning pre-conceptual counseling and post-natal outcomes in WWE in SSA. Conclusion: Our review underscores the need for contextualized evidence-based clinical guidelines and a collaborative approach to treat WWE in SSA. High risks of congenital malformations and drug interactions with first line AED warrant the provision of safer second line alternatives.

A clinical trial performed in the Democratic Republic of Congo (DRC), among persons with epilepsy (PWE) infected with Onchocerca volvulus treated with anti-seizure medication suggested that ivermectin reduces the seizure frequency. We assessed the effect of ivermectin treatment on seizure frequency in PWE with and without anti-seizure medication in three onchocerciasis endemic areas (Maridi, South Sudan; Aketi, DRC; and Mahenge, Tanzania). Pre- and 3–5 months post-ivermectin microfilariae densities in skin snips and seizure frequency were assessed. After ivermectin, the median (IQR) percentage reduction in seizure frequency in the study sites ranged from 73.4% (26.0–90.0) to 100% (50.0–100.0). A negative binomial mixed model showed that ivermectin significantly reduced the seizure frequency, with a larger decrease in PWE with a high baseline seizure frequency. Mediation analysis showed that ivermectin reduced the seizure frequencies indirectly through reduction in microfilariae densities but also that ivermectin may have a direct anti-seizure effect. However, given the short half-life of ivermectin and the fact that ivermectin does not penetrate the healthy brain, such a direct anti-seizure effect is unlikely. A randomized controlled trial assessing the ivermectin effect in people infected with O. volvulus who are also PWE on a stable anti-seizure regimen may be needed to clarify the causal relationship between ivermectin and seizure frequency.

Despite a long history of community-directed treatment with ivermectin (CDTI), a high ongoing Onchocerca volvulus transmission is observed in certain onchocerciasis-endemic regions in Africa with a high prevalence of epilepsy. We investigated factors associated with higher microfilarial (mf) density after ivermectin treatment. Skin snips were obtained from O. volvulus-infected persons with epilepsy before, and 3 to 5 months after ivermectin treatment. Participants were enrolled from 4 study sites: Maridi (South Sudan); Logo and Aketi (Democratic Republic of Congo); and Mahenge (Tanzania). Of the 329 participants, 105 (31.9%) had a post-treatment mf density >20% of the pre-treatment value. The percentage reduction in the geometric mean mf density ranged from 69.0% (5 months after treatment) to 89.4% (3 months after treatment). A higher pre-treatment mf density was associated with increased probability of a positive skin snip after ivermectin treatment (p = 0.016). For participants with persistent microfiladermia during follow-up, a higher number of previous CDTI rounds increased the odds of having a post-treatment mf density >20% of the pre-treatment value (p = 0.006). In conclusion, the high onchocerciasis transmission in the study sites may be due to initially high infection intensity in some individuals. Whether the decreasing effect of ivermectin with increasing years of CDTI results from sub-optimal response mechanisms warrants further research.

Aims . To describe the clinical manifestations of epilepsy and access to antiseizure treatment in Mahenge in Central Tanzania, an onchocerciasis endemic area with a high prevalence of epilepsy. Methods . A door‐to‐door epilepsy prevalence survey was conducted in four rural and two sub‐urban villages. Trained community workers used five screening questions to identify persons suspected to have epilepsy. Such individuals were interviewed and examined by a neurologist or a medical doctor with additional training in epilepsy, and were tested for Onchocerca volvulus antibodies. Results . A total of 221 out of 8,062 (2.74%) surveyed individuals were confirmed to have epilepsy. The median age at seizure onset was 12 years (interquartile range: 7–16). Seventy‐nine persons with epilepsy (PWE) (36.1%) had a family member with epilepsy, which was a sibling in 52.1%. Tonic‐clonic seizures (142 individuals; 64.2%) were the most common seizure type. Nodding seizures were reported in 12.7% of PWE; the majority of them living in rural villages. Persons with nodding seizures reported more frequent seizures, presented with more psychiatric symptoms, and more often had onchocerciasis antibodies than those with other seizure types. The high rate of individuals with a seizure onset at between seven and 16 years is characteristic of onchocerciasis‐associated epilepsy (OAE). Of the PWE, 77.9% met the criteria for the clinical case definition of OAE. Eighty‐three PWE (37.6%) were not taking any antiepileptic medication. Phenobarbital was the antiepileptic drug most commonly prescribed in 76.1% of treated PWE. Conclusion . The high prevalence of epilepsy in rural villages in Mahenge most likely is related to the high prevalence of OAE. To prevent children developing OAE, strengthening the onchocerciasis elimination programme in Mahenge is urgently needed. Moreover, a decentralised epilepsy treatment programme is also needed to provide uninterrupted access to affordable antiepileptic drugs for the many PWE living in rural villages in the Mahenge area.
