The aim of this study was to determine the status of vitamins A, D, E, and C in the blood of a group of children with CFSPID. Material and Methods: A total of 89 children were enrolled in the study (Me: 3.6 years, 52.8% boys), as follows: 28 with CFSPID, 31 with CF (cystic fibrosis), and 30 HC (healthy children). Their blood concentrations of vitamins A, D, E, and C, and their dietary intake of these vitamins were analysed in the study groups on the basis of a three-day food diary. Results: The patients with CFSPID had significantly higher serum vitamin D (p = 0.01) and E (p = 0.04) concentrations, compared to the children with CF. None of the children with CFSPID revealed vitamin A or E deficiencies. Patients with CF had been consuming significantly higher vitamin D and E amounts (p = 0.01). The vitamin concentrations did not depend either on the pancreatic\/liver function or on anthropometric parameters. In total, 32.14% of patients with CF did not cover the baseline recommended calorie intake, and 53.6% and 36% did not take the recommended vitamin E and vitamin A intake, respectively. Conclusion: Children with CF and CFSPID did not fully cover the dietary recommendations for vitamin supply, but vitamin deficiency was found only in CF.<\/jats:p>","DOI":"10.3390\/nu14214661","type":"journal-article","created":{"date-parts":[[2022,11,4]],"date-time":"2022-11-04T04:00:51Z","timestamp":1667534451000},"page":"4661","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Vitamin Status in Children with Cystic Fibrosis Transmembrane Conductance Regulator Gene Mutation"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3038-9646","authenticated-orcid":false,"given":"Paulina","family":"Wysocka-Wojakiewicz","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Faculty of Medical Sciences, Medical University of Silesia, 40-752 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Halina","family":"Wo\u015b","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, University of Bielsko-Biala, 43-309 Bielsko-Bia\u0142a, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Wielkoszy\u0144ski","sequence":"additional","affiliation":[{"name":"Higher School of Strategic Planning and Laboratory Medicine Centre, 41-303 D\u0105browa G\u00f3rnicza, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7520-8506","authenticated-orcid":false,"given":"Aleksandra","family":"Pyziak-Skupie\u0144","sequence":"additional","affiliation":[{"name":"Department of Children\u2019s Diabetology, Silesian Medical University in Katowice, 40-752 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Urszula","family":"Grzybowska-Chlebowczyk","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Faculty of Medical Sciences, Medical University of Silesia, 40-752 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Cystic Fibrosis Foundation, Borowitz, D., Parad, R.B., Sharp, J.K., Sabadosa, K.A., Robinson, K.A., Rock, M.J., Farrell, P.M., Sontag, M.K., and Rosenfeld, M.
