Oleaceae-induced pollinosis in an area with exposure to olive and ash trees

Background: navarre,in northern spain,is an area with moderate exposure to olive and ash tree pollen objective: to assess the relevance of ash as a cause of pollinosis in our region. methods: the study sample comprised 85 patients from navarre with clinical symptoms of pollinosis. specific immunoglobulin e (sige) was determined to fra e 1,ole e 1,and a mixture of amino- and carboxy-terminal domains of ole e 9 (ole e 9 nc) (advia-centaur). at the same time,the presence of sige to other pollen allergens was studied. prick tests were performed with ash pollen (n=33) and olive pollen (n=85) and the symptomatic period was recorded (n=85). as a control group,we studied the serum of 98 patients with olive pollen allergy,intense exposure to olive pollen,and no exposure to ash. results: sensitization to oleaceae was detected in 24/85 patients in the study group (28.2%). in this group,the mean (sd) level of ige to fra e 1 was 8.5 (10) kua/l and to ole e 1 6.07 (7.88) kua/l (p<.001). in the control group,these fi gures were 103.64 (132.19) kua/l and 86.43 (118.5) kua/l (p<.001),respectively. in all patients with positive sige to fra e 1,ige to ole e 1 was also detected (concordance ndex,k=1),both in the study group and in the control group. patients who were sensitized to frae1 did not present a longer symptomatic period and their symptoms did not have an earlier onset. conclusion: we did not find evidence of clinically relevant sensitization to ash in navarre. © 2011 esmon publicidad.
