| Popis: | Can, Demet (Balikesir Author) Background: In recent years, pets keeping has become widespread in Turkey. In parallel, the prevalence of allergy to cat has increased. It is important to distinguish cat allergy from sensitization to cat al-lergen. Studies investigating cat allergy in children are rare. In our study, it was planned to investigate the clinical features of cat allergy and sensitization to cat allergen in children living in big cities. Method: Skin prick test (SPT) included cat allergen was applied to 3499 (16.8%) patients among 20717 patients who applied with any al-lergic complaints to two center of Pediatric Allergy Outpatient Clinics in İzmir and Balıkesir between 01.01.2019– 31.12.2020. Accepted as sensitization to cat allergen if any average wheal diameter was ≥3 mm bigger than the negative control. 140 (4%) children with sensitization to cat allergen were included in this study. Cat allergy was defined as the occurrence of reproducible symptoms or signs initiated by ex-posure to a cat. The patients were divided into groups first as mono-sensitized and polysensitized, and then as those with cat allergy and sensitization to cat allergen. Demographic data, allergic histories and laboratory results of the patients in each group were recorded. SPT threshold values of those with cat allergies were calculated, a ques-tionnaire was applied for the precautions they took for cat allergy. Results: 32% of the patients had sensitization to cat allergen, 68% had cat allergy and the most common symptom was sneezing. 57% of children with cat allergy were male and the mean age was 12.1 years. 17% of children with sensitization to cat allergen and 16% of children with cat allergy were monosensitized. It was found that the threshold value for SPT was 6.3 mm in monoosensitized patients (13.5%) with cat allergy, and the SPT was above 6.5 mm in polysen-sitized patients (86.5%). In the polysensitized group, the most com-mon aroallergens detected sensitivity other than cat allergen were grass and olive tree pollen, respectively. 50% of families to cat al-lergy in their children gave up their ownership of cats and sent them to a relative. 88% of children with cat allergy said that they would like to be allergen- specific immunotherapy (AIT). Conclusion: Cat allergy is more common in boys and the most com-mon complaint is sneezing. In patients with suspicious history, the SPT threshold value may be helpful to differentiate sensitization to cat allergen from cat allergy. Half of those with cat allergies do not give up their cats and prefer AIT. |
