This article delves into the significance of serum vasoactive intestinal peptide, its role in various conditions, and what elevated or decreased levels might indicate.

What is Vasoactive Intestinal Peptide (VIP)?

Vasoactive intestinal peptide, also known as vasoactive intestinal polypeptide or simply VIP, is a neuropeptide. It is synthesized and released by various cells, including neurons in the central and peripheral nervous systems, as well as endocrine cells. Its presence is not confined to the gastrointestinal tissues; it is also found in other organs and can be detected in serum and plasma samples. The VIP axis is a complex system, and its proper functioning is crucial for maintaining homeostasis. Research has indicated that a dysfunctional vasoactive intestinal peptide axis can be linked to various pathological conditions.

The Role of Serum VIP in Diagnosis

The primary application of measuring serum vasoactive intestinal peptide levels is in the diagnosis and management of specific medical conditions, most notably vasoactive intestinal polypeptide-producing tumors, also known as VIPomas. These very rare pancreatic neuroendocrine tumors (PNETs) are characterized by excessive production and secretion of VIP.

When a VIPoma is suspected, particularly in patients presenting with chronic diarrheal diseases, a Vasoactive Intestinal Polypeptide; Vip Test is often ordered.作者：K Nishino·2025—Serum VIP levels are higher in patients with atrial fibrillation with LVAs, suggesting its potential as a noninvasive biomarker for detecting these areas. The serum vasoactive intestinal peptide level is used to measure the VIP level in the bloodSerum Vasoactive Intestinal Peptide as a Novel Biomarker .... A significantly elevated level, often described as serum VIP levels greater than 200 pg/mL, is highly suggestive of a VIPoma. For instance, patients with VIPoma generally have elevated serum VIP levels ranging from 60 to as high as 2100 pg/mL. It is often recommended that serum vasoactive intestinal peptide levels be measured ideally during a bout of diarrhea, as this can further aid in diagnosis.

Beyond VIPomas, research suggests that serum VIP levels may serve as a novel biomarker in other conditions.Vasoactive intestinal peptide (VIP) is a 28-amino-acid peptide known for its potent vasodilator activity and role in various biological functions across ... Studies have indicated that Serum VIP levels are higher in patients with atrial fibrillation with LVAs (Left Ventricular Abnormalities), suggesting its potential as a noninvasive biomarker for detecting these areas.Vasoactive Intestinal Polypeptide (VIP), Plasma - ARUP Lab Furthermore, research has explored the association between serum vasoactive intestinal peptide and conditions like Alzheimer's disease, with some studies observing that serum VIP levels were elevated in AD patients when compared with those in normal controls.Serum levels of vasoactive intestinal peptide (VIP) in ...

VIP Levels in Different Patient Populations

Understanding the normal range of serum vasoactive intestinal peptide is crucial for accurate interpretation. In healthy controls, a median VIP-serum level of 42.44 +/- 2.540 pg/ml (range, 12.9-98.5 pg/ml) has been reported. However, these levels can vary.Vipoma - Endocrine and Metabolic Disorders

Research has investigated serum levels of vasoactive intestinal peptide (VIP) in specific patient groups. For example, studies have examined serum levels of vasoactive intestinal peptide (VIP) in patients with pancreatic cancer and colonic adenocarcinoma compared to healthy individuals. Some findings suggest that Vasoactive intestinal peptide gene polymorphisms, associated with its serum levels, predict treatment requirements in early rheumatoid arthritis, highlighting a potential link between genetic factors and VIP levels in certain inflammatory conditions.

Conversely, other studies have pointed towards lower VIP levels in specific contexts.Endocrine cells derived chemokine vasoactive intestinal polypeptide ... For instance, one study concluded that EA patients with low baseline VIP levels have worse disease outcome, underscoring the prognostic significance of VIP levels in certain patient cohorts.

VIP and Its Physiological Functions

The multifaceted nature of Vasoactive Intestinal Peptide means it is involved in a wide array of biological functions. VIP plays a key role in regulating smooth muscle relaxation, secretion of water and electrolytes in the intestines, and modulation of immune responses. Its potent vasodilator activity contributes to blood flow regulation. Additionally, VIP acts as a mitogenic factor for embryonic neurons in the sympathetic nervous system, underscoring its importance in neural development.2025年8月10日—In healthy controls, amedian VIP-serum level of 42.44 +/- 2.540 pg/ml(range, 12.9-98.5 pg/ml) was found, while patients with pancreatic cancer ... The neuropeptide vasoactive intestinal peptide (VIP) has been identified as inhibiting osteoclastogenesis and suppressing inflammation, pointing to its anti-inflammatory properties.

The Vasoactive Intestinal Peptide Test

The Vasoactive intestinal peptide test is a straightforward blood test designed to quantify the amount of VIP in the bloodstream. To ensure accurate results, specific patient preparation is usually required. Generally, a patient should be fasting for 10-12 hours prior to the collection of the specimen.Plasma Vasoactive Intestinal Polypeptide Concentration ... The blood sample is typically collected in a pre-chilled tube, especially when testing for vasoactive intestinal polypeptide-producing tumors. The Vasoactive Intestinal Polypeptide; Vip Test is readily available through various laboratory services, offering a fast and accurate diagnosis for timely treatment.

Related Considerations for Serum VIP

While VIPomas are a primary focus, other conditions can influence serum VIP levels.
