BACKGROUND: intlammatorybowel diseases(IBD) are et increasedrisk for thrombosis andvitamin deficienciesFew dataexist aboutthe relatianshiobetweenIBD andvitamin B6status Vitamin B6 de6nency is an independentrisk factor for thrombosispet se and by the inductionof hyperhomocystebtemia,which is frequentlyobservedin IBD AIM to evehts,tevitmtin 86 plasmalevelsin IBD patientsandtheir possiblecorrelationswith oatieots’clinicalfeatures.acuteobesereactantsandhvoerbomocvsteieemiaPATIENTS ~METHODS: we &died il IBD patients 32 C’&t’s d&se (IS tttw mean age37 3 + 1I I years) and29 tdcemtivecolitis (IS mea,mean age45.5 + 17 8 years) For each patient,3 gender-and age-matchedhealthycontrols were studied Plasmahomocysteinewas determinedby meansof HPLC. Vitamin B6 levelswere evaluatedby meansof a radiougrmatic asnay Statisticalanalysiswas performedby meansofMann-Whitney, Pishdr exact andSpearmancorrelationtests RESULTS medianwtaedn86 levelswere sigdicdy lower in IBD patients(22 0 pm&, range3 6-231 0 pm&l) than in controls (31.1 pmoVI,range3 7-363.4 pmol/l),(p

Stool sampleswere collected from 99 patientswith IBD (40 CD, 59 UC), 20 with intestinal neoplasticlesions(12 adenwarcinoma, 6 adenoma,2 lymphoma),32 patientswith irritable bowel syndrome (IBS) and 18healthy vokmteers ON) Fecal C was measuredby a quantitativecommercially availableenzyme-linkedimmwtoassey(Calprest, Eurosp~tal, Trieste, Itake) andexpressed es ,,g,g of stoo,; according to the menufacmre?sinstruction., the normalC value wes < 50 ps/B, while strongly positive results were >I00 ,t& Values between 50and lo0 pglg were consideredindetemtinateatd,in ibis study,were not usedfor the performanceevaluationofthe test Statisticalanalysiswas carried out by using the Kroskai-Wellis test and the Fish& exact test The medianC coocentrationr were the following 257 p& (CD), 234 &p/p (UC), 130 flk+d (neoplesia),20 pg/g @BS),25 Kg/g (HV) Valuesfrom patientswith organic disorders (IBD, neoplasta)tomed out to be significantlyhigherthan values from IBS andHV (p
