Copiii predispu\u015fi genetic la diabet zaharat de tip 1 ar putea s\u0103-\u015fi reduc\u0103 riscul de a contracta boala, dac\u0103 primesc suficient\u0103 vitamina D
\nCopiii predispu\u015fi genetic la diabet zaharat de tip 1 ar putea s\u0103-\u015fi reduc\u0103 riscul de a contracta boala, dac\u0103 primesc suficient\u0103 vitamina D. Aceast\u0103 este concluzia unui nou studiu publicat \u00een revista Diabetes, scrie doctorexpres.ro. Cercet\u0103torii au descoperit c\u0103 acei copii care au un nivel sc\u0103zut al vitaminei D \u00een s\u00eenge au avut mai multe \u015fanse de a suferi de autoimunitatea insulelor Langerhans, \u00een compara\u0163ie cu cei care au avut un nivel mai ridicat de vitamina. Autoimunitatea insulelor Langerhan este un proces \u00een care sistemul imunitar atac\u0103 \u00een mod gre\u015fit celulele produc\u0103toare de insulin\u0103 ale pancreasului, provoc\u00eend diabetul de tip 1.<\/p>\n

1,25 milioane de copii \u015fi adul\u0163i din Statele Unite au diabet zaharat de tip 1<\/b><\/p>\n

Autorul studiului, Jill Norris, de la \u015ecoal\u0103 de S\u0103n\u0103tate Public\u0103 din Colorado, a Universit\u0103\u0163ii Anschutz din Aurora, spune c\u0103 studiul este primul care arat\u0103 c\u0103 nivelurile mai ridicate de vitamina D pot ajut\u0103 la prevenirea autoimunit\u0103\u0163ii insulelor.
\nDiabetul de tip 1 este o afec\u0163iune \u00een care organismul nu produce cantit\u0103\u0163i suficiente de insulin\u0103, hormonul care regleaz\u0103 nivelul glucozei din s\u00eenge. Sistemul imunitar lanseaz\u0103 un atac asupra celulelor pancreatice numite insulele Langerhans. Acestea s\u00eent grupuri de celule care con\u0163in celule beta, a c\u0103ror func\u0163ie este s\u0103 detecteze glucoz\u0103 din s\u00eenge \u015fi s\u0103 o elibereze atunci c\u00eend este necesar. C\u0103 urmare a atacului imun asupra insulelor Langerhans, celulele beta nu reu\u015fesc s\u0103 produc\u0103 cantit\u0103\u0163i suficiente de insulin\u0103, determin\u00eend cre\u015fterea nivelului de glucoz\u0103 din s\u00eenge. \u00cen timp ce diabetul zaharat de tip 1 poate ap\u0103rea la orice v\u00eerst\u0103, debutul este cel mai frecvent \u00een copil\u0103rie. Potrivit American Diabetes Association, aproximativ 1,25 milioane de copii \u015fi adul\u0163i din Statele Unite au diabet zaharat de tip 1.<\/p>\n

\u201eVitamina soarelui\u201d<\/b><\/p>\n

Vitamina D este adesea denumit\u0103 \u201evitamina soarelui\u201d \u015fi este prezen\u0163a \u00een alimente precum peste gras, br\u00eenz\u0103 \u015fi g\u0103lbenu\u015furi de ou, dar este disponibil\u0103 \u015fi c\u0103 supliment alimentar. Cercet\u0103torii sugereaz\u0103 c\u0103 direc\u0163ionarea receptorilor de vitamina D poate ajut\u0103 la sc\u0103derea riscului de diabet de tip 2. Dr. Norris \u015fi colegii s\u0103i au investigat dac\u0103 nivelurile de vitamina D afecteaz\u0103 sau nu autoimunitatea insulelor.<\/p>\n

Speran\u0163e pentru viitor<\/b><\/p>\n

Studiul a inclus 8.676 de copii cu risc genetic pentru dezvoltarea diabetului de tip 1. S-au prelevat probe de s\u00eenge de la fiecare copil la fiecare 3-6 luni de la na\u015ftere, timp de p\u00een\u0103 la 4 ani. Aceste probe au fost utilizate pentru a identifica nivelurile de vitamina D \u015fi autoimunitatea insulelor Langerhans. Un total de 376 copii au dezvoltat autoimunitate la insule, iar nivelurile de vitamina D ale acestor copii au fost comparate cu cele ale 1.041 copii care nu au dezvoltat aceast\u0103 afec\u0163iune.
\nCercet\u0103torii au descoperit c\u0103, \u00een r\u00eendul copiilor care au posedat o variant\u0103 a genei receptorului de vitamina D, nivelurile mai ridicate de vitamina D \u00een timpul copil\u0103riei au fost asociate cu un risc redus de a dezvolt\u0103 autoimunitatea insulelor. Norris \u015fi colegii s\u0103i cred c\u0103 rezultatele lor indic\u0103 faptul c\u0103 vitamina D are poten\u0163ialul de a preveni diabetul de tip 1 la copiii genetic predispu\u015fi la afec\u0163iune.<\/p>\n
