Thirty-two patients with spasticity due to multiple sclerosis were entered into a randomized, double-blinded, placebo-controlled crossover trial of the gamma-aminobutyric acid agonist, progabide. Each patient was treated with a maximum of 45 mg/kg of progabide during each of two four-week treatment periods, separated by a two-week washout. Twenty-five participants completed the study; seven failed to complete the study due to adverse events. Progabide was associated with lessened spasticity. There was no loss of motor power associated with progabide. The physician, patients, and study nurse coordinator all declared preferences for progabide for treatment of spasticity. Ten participants (40%) chose to remain on progabide in an open, long-term follow-up protocol. Seven serious adverse events occurred. One consisted of fever and weakness without infection; the other six consisted of elevated aspartate aminotransferase and alanine aminotransferase levels, four of which were asymptomatic. All adverse events resolved entirely when the drug was stopped. Progabide is an effective antispastic agent and its antispastic effect is not accompanied by increased motor weakness. The use of the drug, however, is associated with a high incidence of adverse events, which will likely limit progabide's therapeutic usefulness.

Variants in the ATL1 gene have been repeatedly described as the second most frequent cause of hereditary spastic paraplegia (HSP), a motor neuron disease manifested by progressive lower limb spasticity and weakness. Variants in ATL1 have been described mainly in patients with early onset HSP. We performed Sanger sequencing of all coding exons and adjacent intron regions of the ALT1 gene in 111 Czech patients with pure form of HSP and additional Multiplex-Ligation Probe Analysis (MLPA) testing targeting the ATL1 gene in 56 of them. All patients except seven were previously tested by Sanger sequencing of the SPAST gene with negative results. ATL1 diagnostic testing revealed only five missense variants in the ATL1 gene. Four of them are novel, but we suppose only two of them to be pathogenic and causal. The remaining variants are assumed to be benign. MLPA testing in 56 of sequence variant negative patients revealed no gross deletion in the ATL1 gene. Variants in the ATL1 gene are more frequent in patients with early onset HSP, but in general the occurrence of pathogenic variants in the ATL1 gene is low in our cohort, less than 4.5% and less than 11.1% in patients with onset before the age of ten. Variants in the ATL1 gene are a less frequent cause of HSP among Czech patients than has been previously reported among other populations.

Subacute neuroregression in association with raised neopterin and overexpression of interferon stimulated genes (ISGs) could indicate a type 1 interferonopathy. Here we describe a novel immunotherapy-responsive, clinico-immunological and imaging phenotype with evidence of innate immune activation. Three children (patient 1: 22-month-old boy; patient 2: 5-year-old girl; patient 3: 4-year-old girl) presented with asymmetric bilateral mixed dystonia and spasticity, regression in language (expressive more than receptive) and bulbar symptoms with no evidence of seizures. Symptoms evolved over several weeks to months. Brain MRI changes mimicked cerebral atrophy, initially asymmetric. CSF revealed raised neopterins. Blood RNA assay showed abnormal overexpression of ISGs and transient raised alanine aminotransferase (ALT). Importantly, all three children were treated with intravenous methylprednisolone and immunoglobulin with significant and sustained improvement in their motor and language function, and normalisation of imaging. Immune-mediated encephalitis can masquerade as subacute neuroregression.
