Links between orexin and amyloid processes have been underlined recently. During the Alzheimer's process an upregulation of the orexin mechanism has been observed. The pathophysiological mechanism of narcolepsy type 1 is linked to orexin deficiency. Thus, the investigators hypothesized that patients with narcolepsy may be protected from amyloid brain lesions, hallmarks of the Alzheimer's process. To test this hypothesis, the investigators analyzed the brain amyloid load measured by PET-scan amyloid brain imaging in patients with narcolepsy type 1 compared to controls without cognitive deficits.

Efficacy of 308-nm excimer laser for primary localized cutaneous amyloidosis treatment in Asians, pilot study.

To estimate distribution's parameters of 18F-Flutemetamol (Vizamyl®) fixation on myocardium for patients with amyloid cardiac injuries.

Transthyretin amyloid polyneuropathy (ATTR-PN) is a fatal illness resulting from autosomal dominantly inherited single-point mutations on the transthyretin gene. Tafamidis is a specific stabilizer of both variant and wild-type TTR. Tafamidis binds to TTR at the thyroxine binding sites and inhibits TTR tetramer dissociation, the rate limiting step in the amyloidogenic process. The result disrupts the amyloid cascade and fibril formation and interrupts disease progression. This study provides the basis for the study of the effect of tafamidis on the stability of transthyretin and its safety, tolerance and efficacy in patients with transthyretin amyloid polyneuropathy.

Research Objective:At present, there is no standard therapeutic regimen for monoclonal immunoglobulin light chain (AL) amyloidosis in the world. To compare the efficacy and safety of the regimens between bortezomib-thalidomide-dexamethasone (BTD) and bortezomib-cyclophosphamide-dexamethasone (BCD) in the treatment of AL amyloidosis, so as to provide more clinical evidence for the standard treatment for the disease. Research Design:This study was designed as a prospective, randomized and controlled clinical study. Patients who meet the inclusion criteria of this study will be randomized to the BTD scheme group or BCD scheme group.

Periodic Fever, Aphthous stomatitis, Pharyngitis and cervical Adenitis (PFAPA) is one of the most common, least explored periodic fever syndrome in childhood. This study aims to investigate whether a single dose of an interleukin beta (IL-1) antagonist, Canakinumab will be able to abort PFAPA flares in patients who experience a flare in an average of 2 weeks or less. This will be a single arm open label pilot study. 10 patients will be recruited from 1 center (Pediatric rheumatology unit -Schneider children's medical center of Israel). Patients in ages 2-10 years old who are diagnosed with PFAPA according to clinical criteria at least 3 months prior to enrollment and who are under regular care for this disease (single dose of glucocorticoids during flare) and who suffer from more than 4 PFAPA flares for the last 2 months, will be screened for this study. In the second documented flare, patients will be enrolled to receive a single dose of subcutaneous (SC) Canakinumab 4 mg/kg. The primary outcome is defined as - 50% reduction in PFAPA flares for the next 2 consecutive months as reported by the patient (use of diary) and documented by the patient primary care physician and/ or the researcher in a monthly follow up visits. Secondary outcome measure are define as time to flare (days) and Parent/patient quality of life assessment measured by 100mm visual analog scale (VAS).

INTRODUCTION: Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a very rare manifestation of cerebral amyloid angiopathy, characterized by acute/subacute neurological deterioration and T2/FLAIR corticosubcortical or deep white matter hyperintensity. With the advent of new diagnostic criteria, there are more and more case reports and series reported; nevertheless, MRI findings and follow-up data need to be thoroughly described. OBJECTIVES: Our aim in this multicentrical and retrospective study was to describe the clinical and radiological features of patients with CAA-ri and assess long-term prognosis. METHODS: We reviewed the characteristics of 28 patients with CAA-ri including clinical data, systematic MRI analysis, cerebrospinal fluid results (including Alzheimer's disease biomarkers) and APOE genotype. HYPOTHESIS: We aimed at describing the clinical and radiological characteristics of a cohort of patients with CAA-ri.

Transthyretin is a protein produced in the liver that transports thyroid hormone and vitamin A. A single substitution of an amino acid in the structure of TTR can result in a relatively unstable protein, the breakdown products of which (predominantly monomers) aggregate abnormally and produce proteinaceous deposits in nerves and the heart. These deposits are known as amyloid and produce progressive nerve and heart damage. Amyloidosis due to a mutant TTR is usually an autosomal dominant and hence is a familial condition. Wild-type TTR is also capable of producing amyloid deposits which predominantly involves the heart (rather than the nervous system) resulting in a progressive decrease in cardiac function with increasing signs of heart failure. This study aims to determine whether subcutaneous injection of an antisense oligonucleotide drug, known as inotersen, that has been specifically designed to reduce production of the protein transthyretin by the liver, can slow or stop the progression of TTR amyloid cardiomyopathy as compared to historical controls, using advanced echocardiography and cardiac MRI. The study also aims to determine the tolerability and safety of this drug when administered over a 24-month period to patients with TTR amyloid cardiomyopathy.

This phase II clinical trial aimed at influencing the improvement of major organ functions, especially the objective response rate, in Amyloid light-chain amyloidosis involving myocardium.
