OBJECTIVE: Idiopathic recurrent serositis (IRS) is the most frequent serositis encountered in real-life medical sceneries, and its management represents a therapeutic challenge. There are few epidemiologic data related to IRS, though most studies have focused on recurrent pericarditis, revealing that 70% of all forms of pericarditis are idiopathic and caused by innate immunity abnormalities. The aim of this study was to evaluate outcome and recurrence rates of patients with IRS, assessing management modalities used in our Periodic Fever Centre of the Gemelli Hospital, Rome, Italy, in comparison with previous treatments in other centres. PATIENTS AND METHODS: Retrospectively, we analyzed the medical charts of 57 unselected patients with history of IRS managed during the period 1998-2017. RESULTS: A strong heterogeneity emerged by evaluating treatments of this cohort. In particular, in our Centre there was a larger use of combined therapies: 14 patients out of 27 (52%) were treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and colchicine, compared to only 2 patients (7.4%) previously treated with combined treatments. We used corticosteroid monotherapy only in 1 case, against 7 from other centres. The mean duration of NSAID treatment in other hospitals was 43.8 days (SD ±27.40) and 191.25 days (SD ±42.23) in our Centre; the mean duration of corticosteroid treatment in other hospitals was 101.5 days (SD ±56.40) and 180.7 days (SD ±84.87) in our Centre. Colchicine was administered in other hospitals for the same duration of NSAIDs, and corticosteroids with an average duration of 111 days (SD ±30); conversely, we administered colchicine for an average duration of 250.12 days (SD ±80.7). Relapses of IRS were reported in 1/3 of cases who had discontinued therapies. CONCLUSIONS: The overall duration of treatments to manage IRS has a weight in terms of patients’ outcome. A reduced duration of therapy with corticosteroids and a longer duration of therapy with NSAIDs determine a longer disease-free interval. A significant discriminating effect in terms of risk of IRS recurrence relies in an earlier combination therapy with colchicine independently from the start with either NSAIDs or corticosteroids. Finally, the evaluation of genes causing autoinflammatory diseases has not revealed any pathogenetic variants in a subcohort of 20/57 patients with IRS.
