Abstract

Background: Serum chromogranin A (CgA) is regarded as a reliable marker of neuroendocrine proliferation. We previously described increased serum CgA levels during short‐term profound gastric acid inhibition. Aim: To investigate serum gastrin and CgA levels in dyspeptic patients during continuous medium‐ (6 weeks to 1 year), or long‐term (1–8 years) gastric acid suppressive therapy. Patients and methods: 114 consecutive dyspeptic patients referred for upper gastrointestinal endoscopy were enrolled in a cross‐sectional, case‐control study [62 patients on continuous antisecretory therapy, either with proton pump inhibitors (n = 47) or H 2‐receptor antagonists (H 2 RA) (n = 15) for gastro‐oesophageal reflux disease with or without Barrett’s oesophagus or functional dyspepsia, and 52 age‐ and sex‐matched patients without medical acid inhibition and with normal endoscopic findings (control group)]. Omeprazole doses ranged from 20 mg to 80 mg daily and ranitidine from 150 mg to 450 mg daily. Fasting serum CgA and serum gastrin levels were measured by radioimmunoassay (reference values: serum CgA < 4.0 nmol/L; serum gastrin < 85 ng/L). Results: Fasting serum CgA levels positively correlated with serum gastrin in the entire study population (r = 0.55, P = 0.0001). Median serum CgA values were higher in patients treated with a proton pump inhibitor than H 2 RA [2.8 (2.0–5.9) nmol/L vs. 2 (1.9–2.3) nmol/L, P < 0.002] and controls [2.8 (2.0–5.9) nmol/L vs. 1.8 (1.5–2.2) nmol/L, P < 0.0001) and did not differ between patients treated with H 2 RA or controls. Serum gastrin and CgA levels in patients on proton pump inhibitor therapy positively correlated with the degree and duration of acid inhibition. Patients on long‐term proton pump inhibitor therapy had significantly higher fasting serum gastrin and CgA than those on medium‐term proton pump inhibitor therapy [127 (73–217) ng/L vs. 49 (29–78) ng/L, P < 0.0001 and 4.8 (2.8–8) ng/L vs. 2.1 (1.9–2.6) ng/L, P < 0.001]. No such relation was found in patients on medium‐ vs. long‐term H 2 RA. Overall, patients with positive Helicobacter pylori serology had higher serum gastrin and CgA levels than those with negative H. pylori serology [51 (27–119) ng/L vs. 27 (14–79) ng/L, P = 0.01, 2.4 (1.9–3.4) nmol/L vs. 2.0 (1.7–2.5) nmol/L, P = 0.05]. Conclusions: During long‐term continuous proton pump inhibitor treatment, serum gastrin and CgA levels are significantly elevated compared to H 2 RA treatment and nontreated dyspeptic controls. H. pylori infection seems to affect gastric ECL cell secretory function. Increased serum CgA values during long‐term profound gastric acid inhibition could reflect either gastric enterochromaffin‐like cell hyperfunction or proliferative changes.

  • The longer the use of proton pump inhibitor, the higher the chromogranin A levels will be.

    “Sanduleanu et al (1999) suggested that the longer the use of PPI, the higher the CgA levels will be.”
  • An association between chromogranin A levels and proton pump inhibitor use has already been described: a Dutch cross-sectional study of 114 dyspeptic patients showed chromogranin A levels were higher during long-term proton pump inhibitor treatment than during H2-receptor antagonist treatment or no treatment.

    “An association between CgA levels and the use of PPI has already been described: a Dutch group published a cross-sectional study of 114 dyspeptic patients and showed that CgA levels were higher during long-term PPI treatment than during H2RA treatment, or no treatment (Sanduleanu et al, 1999).”
  • Decrease in acidity leads to release of gastrin.

    “These studies suggested that decrease in acidity leads to release of gastrin.”

    From Discontinuation of proton pump inhibitors during assessment of chromogranin A levels in patients with neuroendocrine tumours (2011) · cites this paper as Sanduleanu et al, 1999

    The supplied passage is bibliographic metadata (no section or page), not a finding about gastrin release. Searches for decreased acidity, gastrin secretion, and acid suppression found no non-abstract passage in our copy establishing the claimed relationship. (LLM, conf=0.70)

  • Elevated gastrin leads to hyperplasia of ECL cells and subsequently to an increase in chromogranin A levels.

    “Elevated gastrin leads to hyperplasia of ECL cells and, subsequently, to an increase in CgA levels (Waldum et al, 1996; Sanduleanu et al, 1999).”

    From Discontinuation of proton pump inhibitors during assessment of chromogranin A levels in patients with neuroendocrine tumours (2011) · cites this paper as Sanduleanu et al, 1999

    The retrieved passages are bibliographic metadata, with no section or page text addressing whether elevated gastrin causes ECL-cell hyperplasia and a subsequent rise in chromogranin A. Searches for ECL cells, enterochromaffin-like cells, and hyperplasia found no substantive passage in our copy to verify that sequence. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
