Trial of Lithium Carbonate for Treatment of Osteoporosis-pseudoglioma Syndrome

Osteoporosis Pseudoglioma

This was a pilot study of 10 patients with Osteoporosis-pseudoglioma syndrome (OPPG) from the Old Order Mennonite community and 16 controls, who did not have OPPG. Five of the 10 OPPG patient elected to participate in the Lithium trial and 5 participated only in baseline data (labs, pQCT). The 5 with OPPG who were given lithium for 6 months had both dual energy xray absorptiometry (DXA), peripheral quantitative computerized tomography (pQCT) and lab assessment at baseline and 6 months. Studies in the mouse model of OPPG showed that lithium normalized their bone strength. Controls (n=16) were recruited from the Old Order Mennonite community, to minimize the effects of environmental and lifestyle factors. The controls were not be given lithium. The age range of participants was 4-64 years.

Prednisolone in Infantile Spasms- High Dose Versus Usual Dose

Infantile SpasmsWest Syndrome

Infantile spasms comprise a difficult to treat type of epilepsy in young children. Hormonal treatment, i.e. Prednisolone and ACTH are considered the treatment of choice. There is no consensus on the dosage of Prednisolone required for the treatment of infantile spasms. Recent data has shown that a high dose (4 mg/kg/day) may be more efficacious than the usual dose (2 mg/kg/day). However, there are no randomized controlled trials comparing these doses. A higher steroid dose may also be associated with more side effects. Therefore, this study was planned to compare the efficacy and tolerability of the high dose versus the usual dose in children with infantile spasms, in a randomized open-label trial design

A Randomized, Controlled Trial of Ganaxolone in Patients With Infantile Spasms

Infantile Spasms

The study consists of cohorts where participants are randomized, in a 2:1 ratio, to 1 of 2 sequences, A and B. In each cohort, Sequence A, comprised of participants, who will receive ascending doses of ganaxolone and ascending doses of placebo. Sequence B, comprised of participants, who will receive ascending doses of placebo and ascending doses of ganaxolone. The dosing level in each subsequent cohort will be based upon experience gained from previous cohorts.

Prednisolone Versus Vigabatrin in the First-line Treatment of Infantile Spasms

Infantile Spasms

Infantile Spasms, is an rare age-specific epilepsy of early infancy. A 2012 American Academy Neurology/ Child Neurology Society practice parameter update on the medical treatment of infantile spasms concluded: adrenocorticotrophic hormone or vigabatrin may be offered for short-term treatment of infantile spasms. There was insufficient evidence to recommend the use of prednisolone, dexamethasone, and methylprednisolone. The cost of ACTH and the side effects of vigabatrin have led to the consideration of alternative medications to treat infantile spasms. The United Kingdom Infantile Spasms Study (UKISS) in 2004, comparing the efficacy of intramuscular synthetic ACTH to high dose oral prednisolone, showed a response rate of 74% for ACTH and 70% for prednisolone. Since the UKISS paper was published, many institutions in the United States and Australia have used oral prednisolone instead of ACTH, partly due to the exorbitant cost of intramuscular ACTH but also its ease of use and better adverse event profile compared to ACTH. Prednisolone and vigabatrin are both oral medications, which can be initiated promptly upon diagnosis of infantile spasms, expediting treatment and shortening treatment lag time. Because the UKISS trial is the only Class 3 study providing evidence for oral prednisolone in the first-line treatment of infantile spasms, further prospective studies are needed.

Trial of the Modified Atkins Diet in Infantile Spasms Refractory to Hormonal Therapy

Infantile Spasms

Infantile spasms comprise an infantile epileptic encephalopathy characterized by hypsarrhythmia on EEG, and frequent neurodevelopmental regression. Unfortunately the treatment of this disorder remains difficult. The first-line options which include hormonal therapy, i.e., adrenocorticotropic hormone (ACTH) or oral corticosteroids, and vigabatrin are effective in 60-70% of the patients. Hormonal therapy is considered the best available treatment. Vigabatrin being expensive and of limited availability is not a feasible option for most patients in our setting. Also, these are however associated with significant side effects, and high relapse rates. Newer drugs such as topiramate, zonisamide, and levetiracetam have also been evaluated; however these drugs are less effective than ACTH. The ketogenic diet (KD) is a high fat, low carbohydrate diet. It has been used for treatment of intractable childhood epilepsy. The KD has also been shown to be effective for intractable infantile spasms; often after ACTH and vigabatrin have failed. The modified Atkins diet is a non-pharmacologic therapy for intractable childhood epilepsy that was designed to be a less restrictive alternative to the traditional ketogenic diet. This diet is started on an outpatient basis without a fast, allows unlimited protein and fat, and does not restrict calories or fluids. Preliminary data have shown efficacy in refractory infantile spasms. This diet is also ideal for resource-constraint settings with paucity of trained dieticians. Hence this study has been planned to evaluate the efficacy and tolerability of the modified Atkins diet in children with infantile spasms refractory to hormonal treatment in a randomized controlled trial.

Multicentre Real-life Follow-up Study of Rare Epileptic Syndromes in Children and Adolescents

EpilepsyWest Syndrome1 more

Rare epilepsies as a whole account for 20-30% of epilepsies, but knowledge about prognostic factors is currently limited. This means that it is difficult to provide adequate information to families at diagnosis and during follow-up. Prognostic factors are also important for management as they can have an impact on the patient's outcome (time to intervention, choice of one molecule over another, etc.). Finally, few treatments are currently available for these epilepsies. One of the limitations to the development of treatments is the lack of real life data as it is difficult to create reliable primary endpoints such as the rate of patients becoming seizure free naturally compared to a therapeutic intervention. The aim of this real-life study is to evaluate the response to treatment as well as to see the evolution of cognitive and psychiatric comorbidities. As explained above, there are very few randomised trials except for 3 rare epilepsies (infantile spasm syndrome, Dravet syndrome, Lennox-Gastaut syndrome). This has led to the virtual absence of management recommendations, including for the three syndromes mentioned above, where attempts at treatment algorithms have been proposed, although these have not been able to be considered as evidence-based recommendations. As a result, there is some diversity in the management of rare epilepsies from one centre to another. However, this diversity in management can be an asset in a real-life study. This will make it possible to compare different management methods, both in terms of seizure control and medium-term outcome.

Growth Hormone for Osteoporosis Pseudoglioma Syndrome

Osteoporosis Pseudoglioma Syndrome

Osteoporosis pseudoglioma (OPPG) syndrome is a rare autosomal recessive condition of childhood osteoporosis and congenital blindness for which new treatments are needed. We have found that body fat is increased in OPPG and muscle mass is reduced. We hypothesize that growth hormone therapy will improve muscle mass and bone strength in OPPG.

Intravenous Methylprednisolone Versus Oral Prednisolone for Infantile Spasms

Infantile Spasm

Infantile Spasms (IS) are classically refractory to the usual antiepileptic drugs and often pose a therapeutic challenge. Since, there is associated significant morbidity, much effort has been directed over the past years to evaluate the role of various anticonvulsants in the management of IS. High dose oral prednisolone has been shown to cause early cessation of spasms and resolution of hypsarrythmia on Electroencephalogram. Recently, role of intravenous methylprednislone pulse therapy has been explored as one of the therapeutic modality in IS, in order to avoid the development of side-effects associated with prolonged oral steroid therapy and maintain long-term efficacy.However, there are no studies comparing iv methylprednisolone pulse therapy with high dose oral prednisolone..
