Other Agents: Carcinoid syndrome diarrhea is treated with SSAs, and telotristat is added when symptoms remain uncontrolled. A positive response to chemotherapeutic agents that treat the underlying NET, thereby reducing tumor activity, may alleviate carcinoid syndrome symptoms.

Why does carcinoid cause diarrhea?

Excess gastrin causes increased motility in the gut and motility means things just rapidly go through it. This is released when you eat and that is why some patients with elevated gastrin levels have diarrhea. Small bowel resection is the most common surgery that is performed on carcinoid patients.

Gastrin is another one. Motilin is another one. Another hormone that helps modulate is the chromogranin-A and these are all important, but the Sandostatin directly works on the motilin, gastrin and the 5-HIAA in reducing your diarrhea.

What does the small intestine do when you have diarrhea?

We eat the food, it goes into our stomach, it is digested and then the small intestine pulls out all the things that our body needs for metabolic and cellular activity. Large intestine or your bowel all it does is absorb water. That is its whole job. So this is how diarrhea happens.

Why do bile salts cause diarrhea?

This is the area that bile salts are released to break down the fats we eat. The bile salts are very irritating to this area and so this release of bile salts leads to diarrhea – rapid motility of the intestine to excrete this substance .

What is the diagnosis of carcinoid syndrome?

Diagnosis of carcinoid syndrome diarrhea is based on symptoms of diarrhea and flushing combined with objective findings of carcinoid tumor through biopsy, multiphase abdominal/pelvic CT, MRI, or biomarkers. 10 The biomarkers 5-hydroxyindoleacetic acid (5-HIAA; found in the urine) and chromogranin A (CgA; found in the serum) have acceptable specificity and sensitivity for carcinoid tumors. 10,11 Serotonin is metabolized by monoamine oxidase to 5-HIAA, and CgA is released from the walls of vesicles that store serotonin. Normal urine 5-HIAA levels range from 3 to 15 mg/24 h; an elevated level has 100% specificity and 73% sensitivity for carcinoid tumors. 11 Serum CgA levels tend to correlate with tumor bulk, but not with symptoms. CgA levels greater than 130 mcg/L are associated with 98.4% specificity and 62.9% sensitivity to carcinoid tumors. 11 Patients should avoid serotonin-rich foods 48 hours prior to urine collection. Urine levels of 5-HIAA can be falsely lowered by levodopa, whereas serum CgA levels can be falsely elevated by proton pump inhibitors, renal insufficiency, or inflammatory conditions. 10-13

How does somatostatin help with diarrhea?

11 SSAs are the mainstay of therapy for carcinoid tumors. Somatostatin influences several GI functions, including GI motility, secretion of pancreatic and intestinal hormones, and secretion of bile and colonic fluids. 13 When binding to receptors, somatostatin inhibits secretion of biologic mediators, which dramatically improves flushing and diarrhea by lowering serotonin, as shown by urine 5-HIAA reductions. 13 Tumor regression is also seen with SSAs. 12,14,15 See FIGURE 1 for the National Comprehensive Cancer Network (NCCN) guidelines for the treatment of carcinoid tumors.

What causes diarrhea in carcinoid syndrome?

Carcinoid syndrome diarrhea is largely a consequence of tumoral secretion of serotonin ( Fig. 1 ). 59 In a healthy individual, serotonin is primarily (95%) found in the GI tract with most secreted by enterochromaffin cells, the cellular source of NETs. Circulating serotonin is exclusively derived from the GI tract and is an important component of normal gut function. 60,61 Excess serotonin increases peristalsis, which results in reduced absorption of water and electrolytes, leading to diarrhea. 59,60,62,63 Patients with CS present with a significant increase in serotonin plasma levels and, consequently, in the levels of soluble urinary metabolite 5-HIAA. 64 Reduction in serotonin production, reflected in lower levels of 5-HIAA, is associated with improvement in CS diarrhea. 61

Is diarrhea a symptom of carcinoid syndrome?

Carcinoid syndrome diarrhea remains a very significant clinical problem with substantial symptom burden resulting in reduced QoL and negative financial impact in patients with metastatic NETs. Although tumor-directed therapy, especially SSAs, remains active, diarrhea may become refractory to conventional therapy. It is important to rule out and treat common morbidities that may mimic CS diarrhea, especially steatorrhea, short gut, dysmotility, and bile acid malabsorption. Telotristat ethyl is a novel agent inhibiting the tryptophan hydroxylase, the rate-limiting step in the production of serotonin by NETs, which is the main driver of CS diarrhea. It has demonstrated statistically significant reductions in bowel movement frequency. However, many patients receiving concurrent SSAs and telotristat ethyl continue to suffer from diarrhea. Peptide receptor radionuclide therapy with DOTATATE lutetium-Lu-177 can alleviate diarrhea in some patients, but better treatments are still needed for patients with poorly controlled symptoms. With a better understanding of the symptomatology and pathophysiology of NET symptom burden, our hope is that standard and novel therapies can be deployed for optimal patient benefit.

What causes diarrhea in carcinoid syndrome?
