The autoinflammatory diseases.

Summary The monogenic autoinflammatory syndromes are conditions caused by mutations of genes coding for proteins that play a pivotal role in the regulation of the inflammatory response. Due to their genetic nature, most of these disorders have an early onset. Clinically they are characterised by recurrent flares of systemic inflammation presenting most of the time as sudden fever episodes associated with elevation of acute phase reactants and with a number of clinical manifestations such as rash, serositis, lymphadenopathy and arthritis. Symptom-free intervals are characterised by complete wellbeing, normal growth and complete normalisation of acute phase reactants. Familial Mediterranean fever (FMF), mevalonate-kinase deficiency (MKD) and tumour necrosis factor (TNF) receptor-associated periodic syndrome (TRAPS) are the three monogenic disorders subsumed under the term periodic fevers, while a systemic inflammation dominated by a characteristic urticarial rash associated with a number of other clinical manifestations is typical of familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and chronic infantile neurological cutaneous and articular syndrome (CINCA). These diseases represent the clinical spectrum of different mutations of a gene named cold-induced autoinflammatory syndrome 1 (CIAS-1, or NLRP3) coding for a protein called cryopyrin. Hence these disorders are also known as cryopyrin-associated periodic syndromes (CAPS). Other conditions are characterised by typical granulomatous formations (granulomatous disorders). Blau's syndrome (familial juvenile systemic granulomatosis) presents with non-caseating granulomatous inflammation affecting the joint, skin, and uveal tract (the triad of arthritis, dermatitis and uveitis) and is associated with mutations of the NACHT domain of the gene CARD15 (or NOD2)

Type I interferonopathies in pediatric rheumatology.

Defective regulation of type I interferon response is associated with severe inflammatory phenotypes and autoimmunity. Type I interferonopathies are a clinically heterogenic group of Mendelian diseases with a constitutive activation of this pathway that might present as atypical, severe, early onset rheumatic diseases. Skin vasculopathy with chilblains and livedo reticularis, interstitial lung disease, and panniculitis are common. Recent studies have implicated abnormal responses to nucleic acid stimuli or defective regulation of downstream effector molecules in disease pathogenesis. As observed for IL1-β and autoinflammatory diseases, knowledge of the defects responsible for type I interferonopathies will likely promote the development of targeted therapy

A Learning Module in Post-Traumatic Stress Disorder (PTSD) and the Use of 3,4-Methylenedioxymethamphetamine (MDMA) Assisted Psychotherapies in Patients who have PTSD and Other Alike Disorders

ABSTRACT Background: Patients who have PTSD are particularly vulnerable to inefficient treatment modalities and subsequent lifelong suffering. Multiple studies have exposed these inefficiencies in conventional therapies and established a potentiality for MDMA use during psychotherapy sessions in this patient population. Ketamine represents an anesthetic with a similar psychedelic profile to MDMA that is used in current clinical settings. Context: Mount Sinai Medical center is a 672-bed hospital in Miami Beach, Florida, where the Miami Beach Anesthesiology Associates (MBAA) group provides anesthesia services. Many procedures requiring anesthesia are carried out to a vast patient population, many of which are patients with PTSD and associative symptoms of depression. Objectives: The objective of the Evidence-Based Learning Module is to expand CRNA knowledge of PTSD and the use of 3,4-Methylenedioxymethamphetamine (MDMA) assisted psychotherapies in patients who have PTSD and other similar disorders. Methods: A pre-implementation survey assessed the providers’ initial knowledge of PTSD, including current treatment modalities and overall inefficiencies, and the pharmacology and history of MDMA. A virtual educational intervention then followed this. When completed, anesthesia providers were redirected to a post-intervention survey to establish the growth of knowledge. Results: Overall, there was an improvement in provider knowledge following the education intervention. There was no change regarding the likelihood of researching MDMA further on the CRNA’s own time. Conclusions: Currently, there exist many insufficiencies in the treatment of patients with PSTD. During the perioperative period, an area of heightened vulnerability for this population, a universal standard of care or anesthetic plan specific to patients with PTSD is lacking. The educational intervention provided was effective in improving anesthesia provider knowledge of PTSD and MDMA

Long-Term Clinical Profile of Children With the Low-Penetrance R92Q Mutation of the TNFRSF1A Gene

Objective: To analyze the long-term impact of the R92Q mutation of TNFRSF1A in children with periodic fever, in comparison with children with tumor necrosis factor receptor-associated periodic syndrome (TRAPS) with TNFRSF1A structural mutations and children with periodic fever of unknown origin fulfilling the criteria for periodic fever, aphthosis, pharyngitis, and adenitis syndrome (PFAPA). Methods: The extracellular region of TNFRSF1A was analyzed in 720 consecutive children with periodic fever, using denaturing high-performance liquid chromatography and DNA sequencing. Followup data on 11 pediatric patients with TNFRSF1A structural mutations (cysteine or T50M), 23 pediatric patients with an R92Q substitution, and 64 pediatric patients with PFAPA were collected during routine clinic visits. The 50-item Child Health Questionnaire was used to assess health-related quality of life (HRQOL). Results: The frequency of typical TRAPS-related clinical manifestations was significantly lower and the impact of the disease on HRQOL was significantly reduced in patients with the R92Q mutation compared with TRAPS patients carrying structural mutations of TNFRSF1A. Followup data on 11 TRAPS patients with TNFRSF1A structural mutations (mean followup 7.9 years), 16 patients with theR92Q substitution (mean followup 7.3 years), and 64 patients with PFAPA (mean followup 5.2 years) were available. Patients with R92Q mutations and patients with PFAPA displayed a higher rate of self-resolution or amelioration of the fever episodes than did TRAPS patients with structural mutations. Conclusion: Although some cases may progress to a more chronic disease course, the majority of children with an R92Q mutation of the TNFRSFA1 gene show a milder disease course than that in children with TNFRSFA1 structural mutations and have a high rate of spontaneous resolution and amelioration of the recurrent fever episodes. \ua9 2011, American College of Rheumatology

Periodic fever syndromes in Eastern and Central European countries: results of a pediatric multinational survey

<p>Abstract</p> <p>Objective</p> <p>To analyze the prevalence of diagnosed and suspected autoinflammatory diseases in Eastern and Central European (ECE) countries, with a particular interest on the diagnostic facilities in these countries.</p> <p>Methods</p> <p>Two different strategies were used to collect data on patients with periodic fever syndromes from ECE countries- the Eurofever survey and collection of data with the structured questionnaire.</p> <p>Results</p> <p>Data from 35 centers in 14 ECE countries were collected. All together there were 11 patients reported with genetically confirmed familial Mediterranean fever (FMF), 14 with mevalonate-kinase deficiency (MKD), 11 with tumor necrosis factor receptor associated periodic syndrome (TRAPS) and 4 with chronic infantile neurological cutaneous and articular syndrome (CINCA). Significantly higher numbers were reported for suspected cases which were not genetically tested. All together there were 49 suspected FMF patients reported, 24 MKD, 16 TRAPS, 7 CINCA and 2 suspected Muckle-Wells syndrome (MWS) patients.</p> <p>Conclusions</p> <p>The number of genetically confirmed patients with periodic fever syndromes in ECE countries is very low. In order to identify more patients in the future, it is important to organize educational programs for increasing the knowledge on these diseases and to establish a network for genetic testing of periodic fever syndromes in ECE countries.</p
