BACKGROUND Intravenous drug abuse is associated with a wide variety of acute and chronic medical complications. The increased longevity of drug users has seen the emergence of new diseases as a result of chronic bacterial and viral infection. We recently observed an increase in the number of cases of renal amyloidosis among intravenous drug users in central London. AIM To describe here the de...

Background Degenerative aortic stenosis (AS) and wild type transthyretin (TTR)-related cardiac amyloidosis (wt-ATTR) share a common demographic and clinical profile. It has been recently suggested that the coexistence of wt-ATTR could negatively influence the outcome of elderly patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). TTR-related cardiac amyloidosi...

Light chain amyloidosis has very rarely been reported in association with chronic lymphocytic leukemia (CLL). We reported on a 76-years-old female who presented with simultaneous kappa-restricted chronic lymphocytic leukemia (CLL) and a lambda-restricted multiple myeloma with plasma cells causing AL amyloidosis involving the heart. While monoclonal immunoglobulins occasionallyproduced by CLL ha...

Amyloidosis is characterized by extracellular deposition of abnormal protein, consisting of primary, secondary, hemodialysis-related, hereditary, senile and localized type. Primary amyloidosis is associated with monoclonal light chains. Secondary amyloidosis is associated with inflammatory, infectious, and neoplastic diseases. Amyloid deposition in the gastrointestinal tract can manifest the sy...

Seminal vesicle (SV) amyloidosis is a well-documented histological entity, but it is observed infrequently. Its incidence is on the rise, which is probably related to the increasing use of prostate biopsies to investigate patients with elevated serum prostate-specific antigen levels. Here, we report seven cases of incidental SV amyloidosis over a 3-year period and consider their relationship to...

AMYLOIDOSIS is a disease characterized by deposition of amyloid proteins in various body tissues. The natural history of primary amyloidosis is poorly understood, and the clinical diagnosis is often not made until the disease is far advanced. There is a high prevalence of conduction disturbances associated with this disease, and heart-related problems are a frequent cause of death for patients ...

Amyloidosis is a rare, mysterious and serious disorder. The extracellular deposition of seemingly homogenous and amorphous material actually represents the expression of very diverse pathologies. All amyloid fibrils share apple green birefringence under polarized light with Congo-red staining, and are arranged in beta-pleated structure on electron microscopy. More than 21 proteins have been ide...

Seven patients (five male and two female) with chronic renal failure (CRF) treated by periodical haemodialysis presented with swelling and effusion of more than three months' duration in knees (four bilateral), shoulders (two, one of them bilateral), elbow (one), and ankle (one). Four had a carpal tunnel syndrome both clinically and electromyographically (three bilateral). All patients had hype...

Amyloidosis is a syndrome characterized by deposition of a highly insoluble protein material in the extracellular space that may affect several organs. It may be generalized and idiopathic (primary amyloidosis). We describe the case of a 48 years-old woman with axonal neuropathy associated with proteinuria, whose final investigation resulted in diagnosis of primary amyloidosis (AL). She was sub...
