Calcium and vitamin D depletion and elevated parathyroid hormone following biliopancreatic diversion

Abstract

Background Biliopancreatic diversion (BPD) is associated with a 70% excess weight loss (EWL) at 10 years, but there are concerns regarding long-term nutritional sequelae. Metabolic bone disease has been documented following Roux-en-Y gastric bypass.Methods Patients who underwent a BPD from 1998 to 2001 were studied. A questionnaire was designed to review BPD patients and collect information on weight loss, frequency of gastrointestinal disturbances and compliance with multivitamin recommendations. The review included a blood test for vitamin D, parathyroid hormone (PTH), alkaline phosphatase (ALP) and calcium.Results Of the 82 patients who underwent BPD during this period, the median %EWL at 36 months was 73.0%. 75.6% suffered diarrhea. At median follow-up of 32 months (18-50), 25.9% of patients were hypocalcemic, 50% had low vitamin D, 23.8% had elevated ALP, and 63.1% had elevated PTH, despite 82.9% taking multivitamins.Conclusion BPD results in significant weight loss. However, 1 in 4 patients are hypocalcemic, and 1 in 2 have a low vitamin D, despite multivitamin supplementation. BPD patients require routine calcium and vitamin D supplementation for life. Long-term sequelae from these abnormal serum levels are not known.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • After BPD/DS, more than 50% of patients have vitamin D deficiency and estimates of secondary hyperparathyroidism range from 60% to 100% even with aggressive supplementation.

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.
