Diagnostic Performance of a Commercial Assay for the Detection of Neuronal Antibodies

Paraneoplastic Neurological SyndromeAutoimmune Encephalitis

Detection of autoantibodies targeting neuronal surface or intracellular antigens is a keystone for the diagnosis and the treatment of auto-immune encephalitis and paraneoplastic neurological syndromes. A strategy commonly used for their detection is to perform a screening with a tissue-based immunofluorescence assay or immunohistochemistry assay and a second line test to confirm and identify the autoantibody. Since several years, commercial kits are used by a growing number of laboratories to screen the presence of these autoantibodies. However, the diagnostic performance of these commercial kits is highly variable and several studies reported a high prevalence of false-positive and false-negative results with commercial immunodots and cell-based assays. It is therefore essential to explore commercial kits limitations in order to avoid false-positive and false-negative results that could lead to misdiagnosis and/or to delay the treatments. To assess the diagnostic performance of commercial kits, the investigators performed a prospective study in which the investigators screened patients neuronal autoantibodies in cerebrospinal fluid and sera using commercial tissue-based indirect immunofluorescence assay and CBAs in comparison with an in-house tissue-based indirect immunofluorescence assay.

Physical Activity Monitoring in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)

Chronic Fatigue Syndrome (CFS)Myalgic Encephalomyelitis (ME)

The investigators will assess the feasibility of activity monitoring armbands for continuous measurement of physical activity level in ME/CFS patients, during 6 months follow-up. The main purpose is to assess if continuous measurement of activity level may be incorporated in outcome measures in future clinical interventional trials.

RAI & HRS: Relationship Between Relative Adrenal Insufficiency and Failure of Treatment in Hepatorenal...

Liver CirrhosisAcute Kidney Injury1 more

Hepatorenal syndrome is a life-threatening medical condition and a serious complication of advanced liver scarring (cirrhosis). It consists of a deterioration of the function of the kidneys caused by a severe alteration in the circulation (blood flow to the kidneys) due to liver cirrhosis. Only around half of the patients respond to treatment which consists of intravenous medication. Moreover, the adrenal glands, which are located on the kidneys, also suffer an alteration in the blood flow leading to deterioration in their function as well. Thus, these patients produced less cortisol than needed; this situation is called "relative adrenal insufficiency". Cortisol is an important hormone necessary in extreme situations such as severe diseases. This is a study which will assess the relationship between the presence of adrenal dysfunction and failure to treatment in patients with hepatorenal syndrome.

Risk Factors for Long-term Opioid Use

Pain Syndrome

Surgeons often see patients with pain to exclude organic pathology and consider surgical treatment. We examined factors associated with long-term opioid therapy among patients with foot/ankle, anorectal, and temporomandibular joint pain to aid clinical decision making. Using the IBM MarketScan® Research Database, we conducted a retrospective cohort analysis of patients aged 18-64 with a clinical encounter for foot/ankle, anorectal, or temporomandibular joint pain (January 2007-September 2015). Multivariable logistic regression was used to estimate adjusted odds ratios for factors associated with long-term opioid therapy, including age, sex, geographic region, pain condition, psychiatric diagnoses, and surgical procedures in the previous year.

Are Sleeping Disorders Associated With Visceral Hypersensitivity in Irritable Bowel Syndrome Patients...

Irritable Bowel Syndrome

Visceral hypersensitivity is frequent in IBS population up to 60% and is correlated with severity and altered quality of life. Sleeping troubles are most frequent in IBS population. Insomnia is a frequent disorder with an important cost for healthcare. Insomnia could decrease pain threshold. Visceral hypersensitivity was never measure in patients with insomnia. The hypothesis is IBS patients with insomnia probably have lower visceral pain threshold. The objective is to assess pain threshold during a barostat procedure in in IBS patients with or without insomnia in comparison with healthy volunteers or patients with insomnia. If the hypothesis are confirmed, insomnia should be look at in IBS patients and its treatments could improve visceral hypersensitivity and IBS symptoms.

Reversible Cerebral Vasoconstriction Syndrome With Concomitant Transient Global Amnesia

Transient Global AmnesiaReversible Vasoconstriction Syndrome

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe, unusual headaches associated with multifocal segmental vasoconstriction of the intracerebral arteries. In addition to headache, focal neurological deficit and/or seizures are quite frequently described, but anterograde amnesia seems to but extremely rare. Indeed, to date, only one case of RCVS associated with transient global amnesia (TGA) has been published. In case of an atypical presentation of TG, associated with brutal headaches, it is important not to ignore an assocation with RCVS because management, treatment, evolution and prognosis are different. Indeed, TGA is a monophasic phenomenon of less than 24 hours duration, without associated complications, which does not require any particular treatment. On the other hand, RCVS, although most often of excellent prognosis, can have severe complications such as intracerebral hemorrhage, subarachnoid hemorrhage, posterior reversible encephalopathy syndrome and cerebral infarction. In order to limit headaches and potential complications, RCVS require special management, including symptomatic treatments for headaches, complete rest, removal of precipitin factors and introduction of calcium channel blockers for a few weeks. This study aim to described three cases of patient who presented with concomitant TGA and RCVS, and to discuss pathogenic mechanism which may be similar in both these pathologies.

Prediction of Outcomes With a Miniaturized Transesophageal Echocardiography Probe in Patients With...

Acute Respiratory Distress Syndrome

The Superior Vena cava Respiratory Collapse Index (cVCS) is a haemodynamic parameter measured exclusively by transoesophageal ultrasound (TEE), which is used to assess cardiac precharge-dependence status. This may be an important prognostic factor in ARDS because it is a sign of hypervolemia and right heart failure.

Exploiting Epigenome Editing in Kabuki Syndrome: a New Route Towards Gene Therapy for Rare Genetic...

Kabuki Syndrome 1

Starting from isolating primary cells from affected patients, an in vitro disease model system for KS will be developed. Using alternative strategies to obtain patient-derived mesenchymal stem cells, an integrative approach will be adopted for defining both the transcriptional and epigenetic regulatory networks perturbed upon the loss of function of KMT2D. Combining the self-renewal potential of mesenchymal stem cells (MSCs) with CRISPR/Cas9 technology, an epigenome editing approach as therapeutic strategy to rescue the activity of MLL4 will be developed. A step forward is expected towards the understanding of those the molecular mechanisms governing the aetiology of Kabuki Syndrome (KS) and that the proposed in vitro disease model will provide to the scientific community an experimental system to study the KS. Importantly, the aim is to define the molecular bases of KS and to develop a therapeutic strategy that could ameliorate some of the abnormalities associated with KS.
