Syndrome of undifferentiated recurrent fever (SURF) is an autoinflammatory disorder that is recognised in an increasing number of patients. In this study, we aimed to assess the data of SURF patients from the main reference centres in our country. Data for this retrospective multicentre observational cohort study were obtained from the records of SURF patients aged 0-18 years who were followed up in 10 pediatric rheumatology clinics in Türkiye between 2010 and June 2023. Patients with recurrent fever that could not be explained by periodic fever, aphthous stomatitis, pharyngitis and adenopathy (PFAPA) and hereditary recurrent fevers and had no other cause were included in the study. Of the 134 patients included in the study, 74 (55.2%) were male. The median age at diagnosis was 67 months. The most common symptom was abdominal pain in 98 (73.1%), arthralgia in 82 (61.2%), malaise in 77 (57.5%). The age at symptom onset was ≤ 5 years in 109 patients (81.3%). Pharyngitis was more common symptom in children aged ≤ 5 years (p = 0.008), headache, arthralgia, chest pain were more common findings in children > 5 years (p = 0.008, p = 0.032, p = 0.045). There were 113 patients receiving colchicine alone or in combination therapy and 74.3% of them achieved complete or partial remission. The presence of abdominal pain (p = 0.021, OR = 0.254) increased the remission rate with colchicine. SURF patients present with a wide range of clinical manifestations. Distinguishing between SURF and PFAPA is not concrete. Further omics studies will enlighten whether there is a true group of SURF. Key Points • SURF is an autoinflammatory disease that is becoming increasingly recognised. • The clinical manifestations of SURF are quite heterogeneous. • Colchicine and anti-IL-1 treatment is effective in most SURF patients. • It is controversial whether it should be called SURF or PFAPA-like syndrome, especially in children aged ≤ 5 years.

Our aim in this study is to reveal the frequency of febrile seizures in patients with Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome and to compare it to normal population. Patients with Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome, who were diagnosed accord- ing to Turkish pediatric Familial Mediterranean Fever diagnostic criteria and Marshall criteria, were enrolled to the study. A form containing questions about febrile seizures history was pre- pared for Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome patients. Demographic data and febrile seizures history of Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis patients were obtained by calling the parents by phone. Familial Mediterranean Fever patients were randomly selected during their routine follow-up. The frequency of febrile seizures in both disease groups was compared with the prevalence of previous febrile seizures studies in the general population in Turkey. A total of 417 Familial Mediterranean Fever and 152 Periodic Fever, Aphthous stomati- tis, Pharyngitis, cervical Adenitis subjects were recruited to the study. The frequency of febrile seizures in Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome was similar (8.4% vs. 8.6%; P > .05). The frequency of febrile seizures in Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome patients was found to be significantly higher than the frequency in general population (8.4% vs. 4.4%) [P < .0001, OR: 1.99 (CI: 1.4-2.8)]; (8.6% vs. 4.4%) [P < .01, OR: 2.03 (CI: 1.1-3.6)], respectively. The frequency of febrile seizures in patients with Familial Mediterranean Fever and Periodic Fever, Aphthous stomatitis, Pharyngitis, cervical Adenitis syndrome was found to be significantly higher than in the general population. This increased frequency of febrile seizures in both periodic syndromes seems to be a result of recurrent fever.

The purpose of this study is to share our experience about clinical findings, natural course, and treatment response rates of a large cohort of patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome. Medical records of patients who were diagnosed with PFAPA syndrome between January 2010 and May 2021 at Istanbul University-Cerrahpasa Cerrahpasa Medical Faculty pediatric rheumatology department were reviewed retrospectively. A total of 607 patients (females: 277, males: 330) with PFAPA syndrome were included. The median duration of episodes was 3 (1-15; interquartile range (IQR) 3-5) days, and the median interval between episodes was 20 days (5-120; IQR 15-30). The median age at the last attack and median disease duration were 66 (24-168; IQR 48-84) months and 40 (4-132; IQR 27.5-60) months, respectively. Fever (100%) was the most common clinical finding, followed by pharyngitis/exudative tonsillitis in 594 (97.9%), aphthous stomatitis in 308 (50.7%), cervical lymphadenopathy in 278 (45.8%), abdominal pain in 249 (41%), and arthralgia in 228 (37.6%) of the patients. Among the clinical findings, there was no statistical difference according to gender, except for cervical lymphadenitis being higher in males (P < .001). Of the patients who were given steroids during attacks, 94.6% were responsive. Colchicine was effective in 93 (63.7%) patients. The disease episodes ceased in 313 (95.4%) of patients who had tonsillectomy/adenoidectomy. Clinicians should be alert for additional symptoms such as abdominal pain, arthralgia, and headache apart from the cardinal signs. Although tonsillectomy is highly effective, its use is controversial. Colchicine may be a good alternative for prophylaxis.
