amyloidosis/diarrhea

Seven patients with familial amyloid neuropathy (AF amyloidosis) were studied to clarify the pathophysiology of the diarrhea associated with this disorder. Fecal weight and fat determinations, 14C-glycocholate breath tests, and a test of B12 absorption were performed before and after treatment with

Early and accurate diagnosis and a prompt initiation of treatment are critical for the prognosis of light-chain amyloidosis. The present article describes a case involving a 62-year-old patient who experienced unexplained, chronic diarrhea with negative duodenal and rectal biopsies. Serum

Severe diarrhea improved dramatically with administration of the humanized anti-interleukin-6 receptor antibody tocilizumab (TCZ) in a patient with secondary reactive amyloidosis, which was associated with rheumatoid arthritis (RA). A 53-year-old woman with RA went into hypovolemic shock because of

A 32-year-old woman presented with Castleman's disease associated with intestinal amyloidosis. The association of amyloidosis and Castleman's disease is very rare, with only 15 cases reported in the literature. To our knowledge, this is the second case in which persistent diarrhea and malnutrition

BACKGROUND Chronic diarrhea in adults is a common symptom with a wide range of underlying etiologies. Although various strategies have been proposed for evaluation, there are still cases with undetermined origins even after extensive workup. Amyloidosis with gastrointestinal (GI) involvement is one

A 53-year-old man complained of orthostatic, non-rotating dizziness, and chronic watery diarrhea of several years duration. His nerve-conduction velocity test revealed peripheral sensory-motor polyneuropathy and he showed an autonomic function abnormality. Echocardiographic examination showed

In secondary amyloidosis (AA type), clinically significant cardiac and gastrointestinal involvement are uncommon, in contrast to the primary type. We report a case presenting with chronic diarrhea and cardiac manifestations who was diagnosed as having AA-amyloidosis with unknown predisposing illness

We report herein a case of intestinal amyloidosis with grave prognosis that caused intractable diarrhea and intestinal pseudo-obstruction, alternately in spite of intensive conservative treatment. A 44-year-old woman was admitted for fever, diarrhea, and crampy abdominal pain which had been

Secondary (AA) amyloidosis is a disease that is caused by systemic deposition of amyloid fibrils. Circulating serum amyloid A protein is an acute phase reactant and levels are therefore high during inflammatory states. Chronic elevation of serum amyloid A levels results in accumulation and

Amyloidosis is a systemic disease caused by the accumulation of extracellular protein into amyloid deposits. Due to the involvement of a variety of organs and tissues, the disease has no specific clinical features and a high rate of misdiagnosis. The present study describes one case of primary

A 53-year-old man with recurrent episodes of large joint pain and a low-grade fever at irregular intervals for 16 years developed right knee and ankle arthralgia, watery diarrhea, and abdominal pain. Following an ileum and colon biopsy, he was diagnosed with gastrointestinal amyloidosis. We

OBJECTIVE The cause of severe diarrhea in patients with systemic amyloidosis is obscure. We therefore performed pathophysiological studies in three such patients in an effort to determine the mechanism of amyloid diarrhea. METHODS Epithelial cell absorption rate of electrolytes was measured during

BACKGROUND Pre-weaning diarrhea (PWD) is a syndrome affecting farm-raised neonatal mink kits. Apart from diarrhea it causes greasy skin exudation, dehydration, and distressed behavior and can ultimately lead to death. No specific causative agents have been identified and the syndrome is regarded as

The acute phase response is a nonspecific inflammatory reaction of the host that occurs shortly after any tissue injury. The response includes changes in the concentration of plasma proteins called acute phase proteins (APPs). Calf diarrhea is an important disease that occurs in association with the

This report concerns two patients with severe protein losing enteropathy and refractory diarrhea due to AA amyloidosis who were successfully treated with corticosteroid and octreotide. In these patients, biopsied tissues from the gastrointestinal (GI) tract showed extensive deposition of AA amyloid,
