Assessments consisted of spirometry, cardiopulmonary exercise testing, quality of life measurements, biochemical markers and assessment by the criterion 4\u2010component model of body composition. Alanine therapy was associated with a 15% gain in total body protein. However, the patient showed no functional improvement and reported feeling worse after treatment. Further controlled studies in a small group may be warranted, but not widespread use of this therapy.<\/jats:p>","DOI":"10.1007\/s10545-006-0238-7","type":"journal-article","created":{"date-parts":[[2006,4,6]],"date-time":"2006-04-06T21:48:10Z","timestamp":1144360090000},"page":"226-229","source":"Crossref","is-referenced-by-count":12,"title":["The effect of <scp>L<\/scp>\u2010alanine therapy in a patient with adult onset glycogen storage disease type II"],"prefix":"10.1002","volume":"29","author":[{"given":"H.
