They have recommended periodic serum magnesium testing in patients prescribed PPIs but provide no guidance on timing of these measurements.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>To our knowledge, we are the first to perform a prospective study to explore specifically proton pump inhibitor associated hypomagnesaemia (PPIAH). We followed 56 patients new to PPIs prospectively as well as a further 100 patients on long term PPIs cross\u2010sectionally to identify what factors may be influencing the development of significant hypomagnesaemia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For the prospective arm of the study, we measured serum magnesium levels prior to starting a PPI and again at regular intervals for the next 8\u00a0months. For the cross\u2010sectional arm of the study we measured serum magnesium levels on patients on PPI therapy ranging from less than 1\u00a0year to over 5\u00a0years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We found that, although there was a significant downward trend in serum magnesium levels in patients new to PPI therapy with time, clinically relevant hypomagnesaemia was not readily identifiable on regular blood testing. We did however identify patients on concurrent diuretic therapy as being at higher risk and so would recommend regular serum magnesium testing alongside their regular renal function monitoring on a more frequent basis such as annually.<\/jats:p><\/jats:sec>","DOI":"10.1111\/bcp.12846","type":"journal-article","created":{"date-parts":[[2015,11,27]],"date-time":"2015-11-27T09:48:43Z","timestamp":1448617723000},"page":"753-758","source":"Crossref","is-referenced-by-count":12,"title":["Proton pump inhibitor associated hypomagnasaemia \u2010 a cause for concern?"],"prefix":"10.1111","volume":"81","author":[{"given":"Joe","family":"Begley","sequence":"first","affiliation":[{"name":"Department of Clinical Biochemistry Royal Bournemouth Hospital  Bournemouth"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Trevor","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Southampton Universities Hospital  Southampton"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kirsty","family":"Barnett","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Royal Bournemouth Hospital  Bournemouth"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Strike","sequence":"additional","affiliation":[{"name":"Department of Statistics Salisbury Hospital  Salisbury"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adnan","family":"Azim","sequence":"additional","affiliation":[{"name":"Diabetes and Endocrine Centre Royal Bournemouth Hospital  Bournemouth"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claire","family":"Spake","sequence":"additional","affiliation":[{"name":"Diabetes and Endocrine Centre Royal Bournemouth Hospital  Bournemouth"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tristan","family":"Richardson","sequence":"additional","affiliation":[{"name":"Diabetes and Endocrine Centre Royal Bournemouth Hospital  Bournemouth"},{"name":"Centre of Postgraduate Medical Research and Education Bournemouth University  Bournemouth UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,1,25]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2036.2006.02943.x"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0149-2918(01)80087-4"},{"key":"e_1_2_9_4_1","unstructured":"Business Services Authority N.
