Sublingual immunotherapy (SLIT) with monomeric carbamylated allergoid administered in accordance with the standard regimen has proven to be effective and safe. Achieving clinical benefit, however, requires a lengthy period of time so it is not very suitable for short-lasting allergies. We thus performed this study to compare an administration protocol starting in the coseasonal period (with a 4-day build-up phase) with a precoseasonal scheme to verify if the former regimen provides the same benefit in a shorter period of time. The prospective, randomized, drug therapy-controlled study was conducted in 33 rhinitic patients monosensitized to Olea with or without asthma. Ten patients were assigned to the coseasonal therapy with 5000 allergic units (AU)/week for 6 weeks, 11 to the precoseasonal therapy with 3000 AU/week for 10 weeks, and 12 to drug therapy. They were treated from April or May to June 2008. A visual analog scale (VAS) was performed at baseline and after treatment to assess the well being of the patients. Drug consumption was evaluated by means of a monthly diary. There was greater VAS improvement in both the SLIT groups versus the controls, but it was statistically significant only in the coseasonal group (p < 0.01). Furthermore, there was a reduction in the rescue medication only in the coseasonal SLIT (p < 0.05 versus drug therapy). One mild adverse event was observed. The allergoid SLIT was shown to be effective and safe in Olea allergy in particular when a coseasonal regimen was used.

The purpose of this study was to evaluate aortic wall thickness after periodontal disease and/or obesity induction in a Wistar rat model.Sixty male Wistar rats were randomly divided into four groups: control (CT), periodontal disease (PD), obesity (OB), and obesity plus periodontal disease (OB+PD). Groups OB and OB+PD received cafeteria diet for 17 weeks. After they had acquired obesity (week 12), periodontal disease was induced by placing a silk ligature on the maxillary right second molar of groups PD and OB+PD. During the experimental period, body weight and Lee index were assessed. Mean alveolar bone loss (ABL) was evaluated, and aortas were prepared for histometric analysis of the aortic wall by ImageJ software. Body weight and Lee index increased in rats exposed to cafeteria diet. Mean ABL was higher in Groups PD and OB+PD than in control and OB (p<0.05). ABL was 18% higher in Group OB+PD than in Group PD, with statistically significant difference (p<0.001). Aortas were thicker in Groups OB and OB+PD than in control and PD groups, respectively (2.31mm ± 0.28 and 2.33 ± 0.29 vs. 2.18 ± 0.26 and 2.14 ± 0.27). Group OB differed significantly from the control group (p=0.036), and OB+PD and OB differed significantly from PD (p=0.004 and p= 0.001, respectively). Obesity alters aortic wall thickness in Wistar rats. However, the presence of periodontal disease did not affect the aortic wall thickness under the conditions of the present study.
