va rugam, spuneti-ne si noua cum sta treaba. Pe prospectul de la acid folic scrie ca este contraindicat in neoplazii. totusi, multe studii arata ca lycopenul si acidul folic determina imbunatatiri fantastice in lupta cu acest virus.... Asadar... un papanicolau marit nu arata o modificare, un proces neoplazic? Luam sau nu acid folic? Sau... cand il luam si cand nu in acest proces?
iata ce se spune aici:
... study to test the hypothesis that systemic concentrations of folate are associated with the occurrence and duration of high-risk HPV infections after controlling for other micronutrients (vitamins B(12), A, E, and C, total carotene) and known risk factors for high-risk HPV infections and cervical cancer. Circulating concentrations of these micronutrients and risk factors for cervical cancer were determined in a cohort of 345 women who were at risk of developing cervical intraepithelial neoplasia. Using the hybrid capture 2 (HC-2) assay, high-risk HPV status was evaluated at 6-month intervals up to 24 months. All women had at least three consecutive visit high-risk HPV test results. Higher folate status was inversely associated with becoming HC-2 test-positive [odds ratio (OR): 0.27; 95% confidence interval (CI), 0.08-0.91; P = 0.04]. Women with higher folate status were significantly less likely to be repeatedly HC-2 test-positive (OR: 0.33; 95% CI, 0.13-0.86; P = 0.02) and more likely to become test-negative during the study (OR: 2.50; 95% CI, 1.18-5.30; P = 0.02). To our knowledge, this is the first long-term prospective follow-up study reporting an independent protective role of higher folate status on several aspects of the natural history of high-risk HPV after controlling for known risk factors and other micronutrients. Improving folate status in subjects at risk of getting infected or already infected with high-risk HPV may have a beneficial impact in the prevention of cervical cancer
?Un studiu american publicat ?n ediţia din Decembrie 2004 a Jurnalului ?Cancer Reseach? a urmărit 345 de femei cu risc ridicat de a dezvolta CIN vreme de 2 ani. Cercetătorii au analizat la 0, 6 şi 24 de luni ?n detaliu colului uterin al pacietelor, efectu?nd şi teste speciale pentru determinarea infecţiei cu HPV. Nivelul ?nalt de acid folic din organism a dus la o diminuare a riscului de a fi pozitive la testul iniţial cu 73% ( 95% CI, 0.08-0.91). Totodată, femeile care au avut un nivel mare de folat au avut o reducere cu 66% (OR: 0.33; 95% CI, 0.13-0.86) a riscului de a răm?ne pozitive la testele virale succesive, dar şi o sansă cu 150% (OR: 2.50; 95% CI, 1.18-5.30) mai mare a de deveni negative la următoarele teste. Cu alte cuvinte, ?n 73% din cazuri, acidul folic poate preveni infecţia cu toate tipurile de papiloma virus (HPV), nu doar cele oncogene, iar ?n 66% din cazuri, femeile care erau iniţial pozitive şi aveau un nivel mare de acid folic ?n organism au devenit negative, lucru ce marchează eliminarea virusului şi a infecţiei.?
Cresterea aportului de acid folic scade riscul de infectie cu HPV; un alt studiu arata ca o concentratie crescuta de trans- and cis-lycopene poate grabi procesul de disparitie a HPV din organism. ( http://www.ncbi.nlm.nih.gov/pubmed/1284 … t=Abstract 2003). Studiile arata ca deficientele de vitamina A, acid folic, zinc, selenium, calciu si fier, utilizarea pilulelor anticonceptionale si fumatul cresc riscul de cancer de col uterin. In special fumatul se pare ca joaca un rol deosebit, avand in vedere ca fumatoarele dezvolta mult mai frecvent cancer de col uterin decat nefumatoarele (http://articles.mercola.com/sites/artic … ?source=nl )
unde se gasesc trans si cis licopen ( trans ? cis Lycopene)? Licopen ( sau licopene) este un carotenoid aciclic, prezent in fructele de catina alba (http://www.univagro-iasi.ro/Horti/Lucr_ … va%20d.pdf), tomate, grapefruit rosu. Este disponibil si in unele suplimente alimentare. Atentie la extractele de lipcopen daca nu este precizat solventul folosit. ( ca idee, ce contine un extract de licopen realizat cu solventi gasiti aici http://eur-lex.europa.eu/LexUriServ/Lex … 045:RO:NOT ( cauta E 160d LICOPEN)
