Multidisciplinary respiratory medicine •
Pidotimod is a synthetic dipeptide that modulates both innate and acquired immunity, with the highest number of scientific publications (as documented in PubMed) which have demonstrated its efficacy and safety in different clinical settings. A board of experts promoted a multidisciplinary Delphi Consensus to increase clinicians' knowledge of the possible areas of pidotimod use and also offer useful tools for informed use based on consolidated data. A series of statements concerning the use of pidotimod in different clinical settings and conditions was anonymously voted on by a panel of qualified Italian specialists, including pediatricians, otorhinolaryngologists, allergologists, and pulmonologists, using a web platform. All the statements obtained full agreement from the panel about the scientific value of evidence on pidotimod efficacy and safety in managing children and adults with recurrent respiratory infections, both in prevention and add-on therapy. In addition, there was agreement about the use of pidotimod in specific situations, including combined therapy (antibiotics plus pidotimod) for pneumonia, Down syndrome, COVID-19, PFAPA, wheezing, and urinary infections. In conclusion, pidotimod is a safe and effective drug helpful in preventing recurrent respiratory infections in susceptible patients and as an adjuvant in managing patients with infections.

Analogies or differences of periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome in children and adults are barely known. The aim of our study was to compare the overall characteristics of a large cohort of patients, both children and adults, diagnosed with PFAPA syndrome. In the last decade, we identified 120 children and 63 adults with periodically recurring fevers, who fulfilled the criteria for PFAPA diagnosis. The two subcohorts were analyzed according to demographic features, clinical manifestations, laboratory data, and responses to therapies. The mean age of onset was 2.4 ± 1.5 and 19.7 ± 10.3 years, respectively, in children and adults, while attacks occurred every 3.8 ± 0.8 and every 4.3 ± 2.3 weeks, respectively, in children and adults. A higher prevalence of exudative pharyngitis was observed in children (58.8%), and the majority of children had only two cardinal signs during flares. In adults, there was a higher interpersonal variability of the intercritical periods. Inflammatory markers measured during non-febrile periods were normal in children but altered in the totality of adults during febrile periods. A strong efficacy of corticosteroids in controlling the pediatric syndrome was observed, but response rates to steroids were less brilliant in adults. Colchicine and interleukin-1 inhibitors were used in the management of the steroid-resistant adult syndrome. Conversely, tonsillectomy was performed in a very low number of children, but was effective in 60.7% of adults when treated after 16 years. The mean age of disappearance of PFAPA symptoms has been 6.4 ± 2.4 years in children, while only 27% of adults have shown a complete drug-free symptom regression. A linear conformity of the PFAPA syndrome has been observed between pediatric and adult patients. PFAPA symptoms tended to disappear with no sequelae in 94.1% of children, while the disease was still active in almost 3/4 of adults at the time of our assessment.
