Home care organization impacts patient management and survival in ALS.

OBJECTIVE: Progression of amyotrophic lateral sclerosis (ALS) depends on several factors linked to the disease. However, both the patient's living place and care organization role need to be evaluated. METHODS: We analysed the effect on survival of factors linked to ALS or the socio-geographical context in a prospective cohort of 203 patients followed between 2003 and 2011. RESULTS: Patients were 97 females and 106 males with a mean age of 65.5 years. Survival was longer in younger patients, in case of upper limb involvement, longer time to diagnosis, and initially higher forced vital capacity. Non-invasive positive pressure ventilation (NIPPV) and percutaneous gastrostomy (PEG) failed to demonstrate benefit. Patients who lived at home had longer survival. The nature of non-medical organization at home statistically influenced survival, which was longer with an organized network than with an unorganized one and shorter in absence of non-medical organization. In patients with indication of PEG and NIPPV, the proposition was statistically different according to the care givers. CONCLUSIONS: Besides the natural history of ALS, survival depended on home organization and the presence or the nature of a home-care system. Home organization was an important factor of decision for NIPPV and PEG proposals.

Anti-N-methyl-D-aspartate receptor encephalitis after Herpes simplex virus-associated encephalitis: an emerging disease with diagnosis and therapeutic challenges.

INTRODUCTION: Morbidity and mortality of Herpes simplex virus encephalitis (HSE) remain high. Relapses of neurological signs may occur after initial clinical improvement under acyclovir treatment. METHODS: We report here a case of post-HSE anti-N-methyl-d-aspartate receptor-mediated encephalitis in an adult and perform a systematic search on PubMed to identify other cases in adults. RESULTS: We identified 11 previously published cases, to discuss diagnostic and therapeutic management. Symptoms in adults are often inappropriate behaviors, confusion and agitation. Diagnosis of anti-NMDA-R encephalitis after HSE is often delayed. Treatment consists in steroids, plasma exchange, and rituximab. Prognosis is often favorable. CONCLUSION: Anti-NMDA-R antibodies should be searched in cerebrospinal fluid of patients with unexpected evolution of HSE. This emerging entity reopens the hot debate about steroids in HSE.
