Carcinoid syndrome is a paraneoplastic syndrome comprising the signs and symptoms that occur secondary to neuroendocrine tumors (formerly known as carcinoid tumors). [1] The syndrome is caused by neuroendocrine tumors most often found in the gut releasing biologically active substances into the blood causing symptoms such as flushing and diarrhea, and less frequently, heart failure, vomiting ...
This can occur as a result of alcoholism, long-term diarrhea, carcinoid syndrome, Hartnup disease, and a number of medications such as isoniazid. [1] Diagnosis is typically based on symptoms and may be assisted by urine testing. [3] Treatment is with either niacin or nicotinamide supplementation. [1]
A carcinoid (also carcinoid tumor) is a slow-growing [1] type of neuroendocrine tumor originating in the cells of the neuroendocrine system. In some cases, metastasis may occur. Carcinoid tumors of the midgut (jejunum, ileum, appendix, and cecum) are associated with carcinoid syndrome. Sometimes, carcinoids cause paraneoplastic syndromes, which ...
Hartnup disease (also known as " pellagra -like dermatosis " [1] and "Hartnup disorder" [2]) is an autosomal recessive [3] metabolic disorder affecting the absorption of nonpolar amino acids (particularly tryptophan that can be, in turn, converted into serotonin, melatonin, and niacin). Niacin is a precursor to nicotinamide (both are forms of ...
A small intestine neuroendocrine tumor is a carcinoid in the distal small intestine or the proximal large intestine. It is a relatively rare cancer and is diagnosed in approximately 1/100000 people every year. In recent decades the incidence has increased. [1] The prognosis is comparatively good with a median survival of more than 8 years. [2]
Lanreotide. Lanreotide, sold under the brand name Somatuline among others, is a medication used in the management of acromegaly and symptoms caused by neuroendocrine tumors, most notably carcinoid syndrome. It is a long-acting analogue of somatostatin, like octreotide. Lanreotide (as lanreotide acetate) is manufactured by Ipsen.
Carcinoid syndrome is a rare condition characterized by an abnormal increase in circulating biologically active hormones, largely serotonin, with early symptoms involving diarrhea, abdominal cramping and episodic flushing. [7] Excess circulating serotonin is usually manufactured by EC-cell-originated carcinoid tumors in the small bowel or appendix.
Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [2] MTC was first characterized in 1959.
