Virusul herpetic s-ar putea afla \u00een spatele a cel pu\u0163in jum\u0103tate dintre cazurile de boal\u0103 Alzheimer, conform teoriei unei cercet\u0103toare din Marea Britanie, citat\u0103 vineri de Press Association.<\/span><\/strong><\/p>\n

Exist\u0103 dou\u0103 tipuri de virus herpes simplex (HSV) – HSV1, cunoscut drept herpes oral, ce provoac\u0103 ulcera\u0163ii \u015fi r\u0103ni \u00een jurul gurii \u015fi pe fa\u0163\u0103; \u015fi HSV2, \u00een general responsabil de cazurile de herpes genital, potrivit Agerpres.<\/p>\n

Ruth Itzhaki, profesoar\u0103 la Universitatea din Manchester, care \u015fi-a petrecut peste 25 de ani studiind o posibil\u0103 asociere \u00eentre virusul herpetic \u015fi boala Alzheimer, a analizat cazul statului Taiwan, una dintre pu\u0163inele \u0163\u0103ri care colecteaz\u0103 date de la popula\u0163ie necesare pentru testarea acestei teorii.<\/p>\n

99,9% dintre locuitorii din Taiwan sunt cuprin\u015fi \u00eentr-o baz\u0103 de date pentru cercetare \u00een cadrul sistemului na\u0163ional de asigur\u0103ri de s\u0103n\u0103tate, care este ”minat\u0103” intens pentru colectarea de informa\u0163ii cu privire la infec\u0163iile microbiene \u015fi afec\u0163iuni.<\/p>\n

\u00cen 2017-2018 au fost publicate trei studii care au descris datele din Taiwan asupra dezvolt\u0103rii demen\u0163ei senile – a c\u0103rui cauz\u0103 principal\u0103 este boala Alzheimer – \u015fi tratamentul pacien\u0163ilor cu semne evidente de infec\u0163ii cu HSV or virus varicelo-zosterian (VZV).<\/p>\n

”Rezultatele uimitoare con\u0163in dovezi conform c\u0103rora riscul de demen\u0163\u0103 senil\u0103 este mult mai mare la cei care sunt infecta\u0163i cu HSV, iar tratamentul contra virusului herpetic provoac\u0103 o sc\u0103dere a num\u0103rului celor afecta\u0163i \u00een mod sever de HSV1 care provoac\u0103 mai t\u00e2rziu demen\u0163\u0103”, a explicat Itzhaki.<\/p>\n

”HSV1 poate sta la baza a 50% sau mai mult dintre cazurile de Alzheimer”, a ad\u0103ugat cercet\u0103toarea care a ad\u0103ugat c\u0103 ”rezultatele acestor studii realizate \u00een Taiwan se aplic\u0103 doar \u00een cazurile de infec\u0163ii severe cu HSV1 (sau VZV), care sunt rare”.<\/p>\n

”\u00cen mod ideal, am studia ratele cazurilor de demen\u0163\u0103 \u00een r\u00e2ndul persoanelor care au suferit infec\u0163ii u\u015foare HSV1, inclusiv herpes labialis sau herpes genital \u00een form\u0103 u\u015foar\u0103, \u00eens\u0103 acestea sunt de departe mai pu\u0163in documentate”, a subliniat autoarea studiului publicat \u00een jurnalul \u015ftiin\u0163ific Frontiers in Ageing Neuroscience.<\/p>\n

Profesor Itzhaki a demonstrat anterior c\u0103 leziunile ulceroase sunt mai frecvente la purt\u0103torii de APOE-4, o muta\u0163ie genetic\u0103 ce cre\u015fte riscul de apari\u0163ie a bolii Alzheimer.<\/p>\n

”Teoria noastr\u0103 sus\u0163ine c\u0103 la purt\u0103torii APOE-4 reactivarea este mult mai frecvent\u0103 sau mai d\u0103un\u0103toare \u00een cazul celulelor neuronale infectate cu HSV1, care se deterioreaz\u0103 progresiv, proces ce culmineaz\u0103 cu apari\u0163ia Alzheimer”, a ad\u0103ugat Ruth Itzhaki.<\/p>\n

\u00cen opinia dr. James Pickett, director \u015ftiin\u0163ific \u00een cadrul Alzheimer’s Society, cercetarea subliniaz\u0103 studii actuale conform c\u0103rora persoanele infectate cu virusul herpetic ar fi mai expuse riscului de apari\u0163ie a demen\u0163ei, \u00eens\u0103 nu demonstreaz\u0103 o rela\u0163ie cauz\u0103 – efect \u00eentre herpes \u015fi demen\u0163\u0103.<\/p>\n

”Herpesul este un subiect fierbinte \u00een studiul demen\u0163ei – infec\u0163ia pare a fi mai frecvent\u0103 \u00een cazul creierelor persoanelor cu Alzheimer \u00een compara\u0163ie cu cele s\u0103n\u0103toase, \u00eens\u0103 nu \u015ftim \u00eenc\u0103 suficient de multe despre rela\u0163ia dintre cele dou\u0103”, a subliniat dr. Pickett ad\u0103ug\u00e2nd c\u0103 ”este nevoie de mai multe cercet\u0103ri pentru a se stabili dac\u0103 medicamentele antivirale pot reduce riscul de demen\u0163\u0103”.<\/p>\n

”\u00cen Marea Britanie, o dat\u0103 la fiecare trei minute o persoan\u0103 dezvolt\u0103 demen\u0163\u0103, iar oamenii de \u015ftiin\u0163\u0103 de la Institutul pentru studiul demen\u0163ei lucreaz\u0103 din greu pentru a \u00een\u0163elege de ce se \u00eent\u00e2mpl\u0103 acest lucru pentru a identifica modalit\u0103\u0163ile de combatere a acesteia”, a ad\u0103ugat James Pickett.<\/span><\/p>\n
