Policitemija vera je redak, sporo napreduju\u0107i oblik raka krvi kod koga ko\u0161tana sr\u017e proizvodi previ\u0161e crvenih krvnih zrnaca. Policitemija vera tako\u0111e mo\u017ee da rezultira proizvodnjom previ\u0161e drugih tipova krvnih \u0107elija, poput belih krvnih zrnaca ili krvnih plo\u010dica. Ove prekomerne \u0107elije \u010dine krv gu\u0161\u0107om i dovode do pojave komplikacija, poput rizika od stvaranja krvnog ugru\u0161ka ili krvarenja. <\/span><\/p>\n

Simptomi<\/span><\/h2>\n

Budu\u0107i da se obi\u010dno sporo razvija, pacijent mo\u017ee godinama da ima ovo oboljenje bez da primeti bilo kakav znak ili simptome. Kod mnogih pacijenata policitemija vera \u010dak i ne mora da dovede ni do kakvog znaka ili simptoma. \u00a0Me\u0111utim, neki osobe mogu da osete slede\u0107e probleme: <\/span><\/p>\n

Visok krvni pritisak;<\/span><\/p>\n

Glavobolje i zamu\u0107en vid;<\/span><\/p>\n

O\u0161amu\u0107enost;<\/span><\/p>\n

Slabost;<\/span><\/p>\n

Prekomerno znojenje;<\/span><\/p>\n

Nelagodnost u stomaku;<\/span><\/p>\n

Bolno oticanje jednog zgloba, obi\u010dno na palcu noge; <\/span><\/p>\n

Te\u0161ko\u0107e u disanju dok pacijent le\u017ei;<\/span><\/p>\n

Utrnulost. golicanje, \u017earenje ili slabost u rukama, stopalima i nogama;<\/span><\/p>\n

Ose\u0107aj nadutosti i sitosti u gornjem levom delu stomaka zbog ote\u010denosti slezine;<\/span><\/p>\n

Crvena ko\u017ea, naro\u010dito u predelu lica, ruku i stopala;<\/span><\/p>\n

Problemi sa krvarenjem\u00a0 – poput onog iy nosa i brz nastanak modrica;<\/span><\/p>\n

Giht, koji mo\u017ee da uzrokuje bolove u zglobovima, ukru\u0107enost i otok. <\/span><\/p>\n

\u00a0<\/span><\/p>\n

Uzroci<\/span><\/h2>\n

Policitemija vera javlja se kada mutacija u \u0107elijama ko\u0161tane sr\u017ei uzrokuje problem vezan za proizvodnju krvnih \u0107elija. U normalnim uslovima, telo pa\u017eljivo reguli\u0161e broj svakog od tri tipa krvnih \u0107elija. Me\u0111utim, kod policitemije vera, ovaj regulatorni mehanizam biva o\u0161te\u0107en i ko\u0161tana sr\u017e proizvodi previ\u0161e \u0107elija jednog tipa. Smatra se da mutacija koja se javlja kao posledica policitemije vera, uti\u010de na proteinski svi\u010d koji navodi \u0107eliju na abnormalno umno\u017eavanje. Ve\u0107ina osoba sa policitemijom vera ima ovu vrstu mutacije. Nije jasan njen uzrok, ali nau\u010dnici veruju da se ona javlja nakon za\u010de\u0107a, tako da se mo\u017ee re\u0107i da se radi o ste\u010denom, a ne poreme\u0107aju koji se nasle\u0111uje od roditelja. <\/span><\/p>\n

\u00a0<\/span><\/p>\n

Fakori rizika<\/span><\/h2>\n

Rizik od policitemije vera pove\u0107ava se sa godinama. Mnogo se \u010de\u0161\u0107e javlja kod osoba starijih od 60 godina, iako se bolest mo\u017ee javiti u bilo kom uzrastu. <\/span><\/p>\n

\u00a0<\/span><\/p>\n

Komplikacije<\/span><\/h2>\n

Bez ikakvog ili bez adekvatnog le\u010denja, policitemija vera mo\u017ee da bude opasna po \u017eivot. Me\u0111utim, uz odgovaraju\u0107u lekarsku negu, mnoge osobe mogu da osete samo par problema vezanih za ovu bolest. Tokom vremena, postoji rizik od progresivnih promena ka te\u017eim oblicima raka krvi, poput mijelofibroze ili akutne leukemije. <\/span><\/p>\n

Me\u0111u mogu\u0107e komplikacije izazvane policitemijom vera spadaju:<\/span><\/p>\n

Krvni ugru\u0161ci<\/span><\/p>\n

Pove\u0107ana slezina<\/span><\/p>\n

Problemi sa ko\u017eom<\/span><\/p>\n

Problem vezani za visok nivo crvenih krvnih zrnaca<\/span><\/p>\n

Drugi poreme\u0107aji krvi<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Prevencija<\/span><\/h2>\n

Na\u017ealost, ne postoji na\u010din da se spre\u010di policitemija vera. Me\u0111utim, rizik od sekundarne policitemije mo\u017ee da se smanji zdravim na\u010dinom \u017eivota i ne provo\u0111enjem puno vremena na velikim nadmorskim visinama. tako\u0111e, simptomi i komplikacije mogu biti spre\u010deni ili odlo\u017eeni uz odgovaraju\u0107i le\u010denje. <\/span><\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-71340","disease","type-disease","status-publish","hentry"],"yoast_head":"\nPolicitemija vera - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"sr_RS\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Policitemija vera - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Policitemija vera je redak, sporo napreduju\u0107i oblik raka krvi kod koga ko\u0161tana sr\u017e proizvodi previ\u0161e crvenih krvnih zrnaca.
