Argon gas knife combined with cryotherapy for amyloidosis leading to severe airway stenosis
Publication date: Available online 14 October 2019Source: Respiratory Medicine Case ReportsAuthor(s): Chunli Che, Fushi Dong, Xue Wu, Wei Wang, Lixue JiangAbstractObjectiveThis case report shows that bronchoscopy is an important method to treat severe airway stenosis caused by bronchial amyloidosis. Bronchoscopic forceps were used to incise the intra-tracheal lump repeatedly. The incision was frozen with a cryosurgery probe, argon knife was used to stop the bleeding until the airway lumen stenosis was reduced to approximately 40%, after which, it continued to enter the lumen. We used bronchoscopic biopsy forceps to repeate...

An Unusual Cause of CPAP Intolerance
Continuous positive airway pressure (CPAP) is a first-line treatment for obstructive sleep apnea (OSA). However, the adherence to CPAP can be difficult for patients due to several reasons. In this case report we describe a patient with severe OSA who initially was treated successfully with CPAP, but after a few months adherence problems developed because of macroglossia. This was caused by amyloidosis due to multiple myeloma. During treatment with chemotherapy and stem cell transplantation, the size of the patient’s tongue decreased and he could successfully use his CPAP device again.Citation:van Loenhout L, van der ...

Cardiac amyloidosis—an underdiagnosed cause of heart failure in the elderly
We present the case of an 84-year-old man with chest tightness, dyspnoea, and ascites. He had a history of dyslipidaemia and ischaemic heart disease. Initial investigations showed severe diastolic dysfunction and elevated pulmonary artery systolic pressure on echocardiogram along with elevated serum natriuretic peptides. Further evaluation by a magnetic resonance imaging scan of the heart and endomyocardial biopsy confirmed the diagnosis of senile systemic amyloidosis. He made good progress after treatment with conventional heart failure drugs and is currently under consideration to start on specific medications to slow do...

Recognising and understanding cryopyrin-associated periodic syndrome in adults.
Abstract Cryopyrin-associated periodic syndrome (CAPS) is a group of rare hereditary autoinflammatory diseases characterised by recurrent flares of mild to severe systemic inflammation and fever. CAPS is the umbrella term for a spectrum of individual conditions, namely familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and neonatal-onset multisystem inflammatory disease (NOMID), also known as chronic infantile neurologic, cutaneous and articular (CINCA) syndrome. The flare symptoms include fever, fatigue, rashes, headaches, arthralgia and myalgia that can last for a few hours or for severa...

Differential roles of plasma protein corona on immune cell association and cytokine secretion of oligomeric and fibrillar beta-amyloid.
In this study, the effects of the plasma protein corona have been investigated with regard to the blood cell association and cytokine secretion of oligomeric (Aβo) and fibrillar Aβ1-42 (Aβf), two major forms of the peptide aggregates. Aβo displayed little change in membrane association in whole blood or washed blood (i.e., cells in the absence of plasma proteins) at 37 ºC, while Aβf showed a clear preference for binding with all cell types sans plasma proteins. Immune cells exposed to Aβo, but not to Aβf, resulted in significant expression of cytokines IL-6 and TNF measured in real-t...

Approach to the Diagnosis of Amyloidosis
AbstractAmyloidosis is heterogeneous group of disorder characterized by extracellular deposition of misfolded insoluble proteinaceous material with cross beta pleated sheet structure leading to organ dysfunction. This disease is rare and indeed heterogeneous, as it may be hereditary (familial amyloidosis), secondary to spectrum of inflammatory conditions (AA amyloidosis) or member of plasma cell neoplasm family (AL amyloidosis). AL amyloidosis is the most common type of amyloid, however, is rarely accompanied by multiple myeloma or other lymphoproliferative disorder. This disparity in its origin and presentation needs to b...

Hepatocyte-Targeted Delivery of siRNA Polyplex with PEG-Modified Lactosylated Dendrimer/Cyclodextrin Conjugates for Transthyretin-Related Amyloidosis Therapy.
Abstract Targeted drug delivery system (DDS) is required for RNA interference (RNAi) therapy to increase the therapeutic effect and to reduce the adverse effect. Especially in transthyretin (TTR)-related amyloidosis, hepatocyte specific delivery is desired because TTR mainly expresses in hepatocyte. Herein, we report on a hepatocyte-specific small interfering RNA (siRNA) delivery system using polyethylene glycol (PEG)-modified lactosylated dendrimer (generation 3; G3) conjugates with α-cyclodextrin (PEG-LαCs (G3)) for TTR-related amyloidosis therapy, and investigated the in vitro and in vivo gene silen...

Diagnosis and Treatment of Cardiac Amyloidosis Related to Plasma Cell Dyscrasias
Light chain amyloidosis is a deadly disease in which a monoclonal plasma cell dyscrasia produces misfolded immunoglobulin light chains (AL) that aggregate and form rigid amyloid fibrils. The amyloid deposits infiltrate one or more organs, leading to injury and severe dysfunction. The degree of cardiac involvement is a major driver of morbidity and mortality. Early diagnosis and treatment are crucial to prevent irreversible end-organ damage and improve overall survival. Treatment of AL cardiac amyloidosis involves eliminating the underlying plasma cell dyscrasia with chemotherapy and pursuing supportive heart failure manage...

Mutations promoting proteolytic remodeling and tetramer dissociation result in fragmented and full-length TTR monomers that misfold, aggregate and deposit at multiple sites (mainly nerves and heart) causing peripheral neuropathy and/or cardiomyopathy.

Transthyretin Cardiac Amyloidosis and Aortic Stenosis: Connection and Therapeutic Implications.
CONCLUSION: The relationship between aortic stenosis and transthyretin cardiac amyloidosis is not well understood. A few studies have proven successful surgical management when both conditions coexist. This systematic review suggests that transthyretin cardiac amyloidosis is common in elderly patients with aortic stenosis and tend to have high mortality rates after AVR. The significant incidence of the two diseases occurring simultaneously warrants further investigation to improve management strategies in the future.

Structural mapping of oligomeric intermediates in an amyloid assembly pathway
Transient oligomers are commonly formed in the early stages of amyloid assembly. Determining the structure(s) of these species and defining their role(s) in assembly is key to devising new routes to control disease. Here, using a combination of chemical kinetics, NMR spectroscopy and other biophysical methods, we identify and structurally characterize the oligomers required for amyloid assembly of the protein DN6, a truncation variant of human β2-microglobulin (b2m) found in amyloid deposits in the joints of patients with dialysis-related amyloidosis. The results reveal an assembly pathway which is initiated by the fo...

Transthyretin cardiac amyloidosis: an update on diagnosis and treatment
AbstractTransthyretin cardiac amyloidosis (ATTR ‐CA) demonstrates progressive, potentially fatal, and infiltrative cardiomyopathy caused by extracellular deposition of transthyretin‐derived insoluble amyloid fibrils in the myocardium. Two distinct types of transthyretin (wild type or variant) become unstable, and misfolding forms aggregate, r esulting in amyloid fibrils. ATTR‐CA, which has previously been underrecognized and considered to be rare, has been increasingly recognized as a cause of heart failure with preserved ejection fraction among elderly persons. With the advanced technology, the diagnostic tools have...
