Conclusion
PFAPA
DISEASE
PFAPA is the disease of unknown aetiology. With our work, we tried to provide a comprehensive view of PFAPA, its clinical and laboratory picture and therapeutic possibilities. We characterised the Slovak cohort of PFAPA patients for the first time. However, our results are also relevant for patients in other countries. It is the second work to date which has proven a possible prophylactic effect of ketotifen on frequent PFAPA attacks and the first work with such a large cohort of patients treated with ketotifen. Further research in this area is needed to confirm our findings.
