Seasonal influenza is a frequent cause of hospitalization and mortality among patients with systemic autoimmune diseases. Despite this evidence, vaccination coverage is generally much lower than the minimum 75% target proposed by the WHO. Therefore, an active campaign was implemented in the years 2019/2020 and 2020/2021 within the Rheumatology Department of the Niguarda Hospital (Milan, Italy) to improve the vaccination coverage in patients with inflammatory arthritis. This study aims to evaluate the vaccination coverage in the 2019/2020 and 2020/2021 (active campaigns) seasons and to compare these results with the 2018/2019 season. A monocenter observational study was conducted among adult patients with rheumatoid arthritis, spondylarthritis, or psoriatic arthropathy, who were referred to the Rheumatology Department of the Niguarda Hospital. Patients were given a questionnaire to investigate previous years' vaccination coverage and to propose an influenza vaccine for the 2020/2021 season. Compared with 2018/2019, a trend for increase in vaccination coverage was reported in 2019/2020 season (+ 10.7%, p = 0.055; 45.5% of coverage) and a statistically significant increase was reported in 2020/2021 (+ 31.2%, p < 0.001; 65.9% of coverage). The increase was also significant when comparing the 2020/2021 and 2019/2020 seasons (+ 20.5%, p < 0.001). The greatest increase in vaccination coverage was observed among under-65-year-old patients. Obtained results support the implementation of active vaccination campaigns to increase vaccination coverage among patients with systemic autoimmune diseases and highlight the importance of external factors (such as the COVID-19 pandemic) in directing the patient to adopt preventive measures to avoid infections and related complications., (© 2022.

Background: Little evidence is available about the impact of diet on disease activity of axial spondyloarthritis (axSpA). This study evaluated the impact of a 6-month nutritional advice based on the Mediterranean diet on the disease activity of axSpA., Methods: We prospectively collected the information of a group of axSpA patients who were offered nutritional advice for a 6-month period, who were compared to axSpA patients followed at the same center who were not on a specific diet. A nutritionist gave suggestions for dietary modification at baseline and thereafter every 2 months until month 6. Adherence to the Mediterranean diet was evaluated with the PREDIMED questionnaire ranging from 0 (no adherence) to 10 (optimal adherence); disease activity was evaluated with ASDAS-CRP. A multivariable regression analysis was conducted to identify independent predictors of PREDIMED and of ASDAS-CRP improvement (improvement ≥ 20% of each score)., Results: A total of 161 patients were included: 81 receiving nutritional advice and 80 controls; 47 in the nutritional group and 63 controls had complete information until month 6. Overall, 40 (36.4%) were females, the mean age was 51.7 ± 1.3 years, and 58 (52.7%) were affected with psoriasis. No relevant change of anthropometric or laboratory measures was observed in either group. Adherence to the Mediterranean diet was moderate (PREDIMED score 6.7 ± 1.8 at baseline; 7.6 ± 2.1 at month 6) and improved more in the nutritional group compared to controls (p = 0.020). Predictors of a PREDIMED improvement ≥ 20% were receiving nutritional advice (OR 4.53, 1.36-15.1, p = 0.014), age (per 10-year increase OR 1.05, 1.02-1.68, p = 0.007), and BMI (OR 0.77, 0.63-0.9, p = 0.006). An ASDAS-CRP improvement ≥ 20% was more frequent in the nutritional group compared to controls (p = 0.020). A PREDIMED improvement ≥ 20% was associated with a ASDAS-CRP improvement ≥ 20% (OR 6.75,1.8-25.3, p = 0.005). Psoriasis and disease duration were negatively but not significantly associated to the ASDAS-CRP improvement., Conclusions: Improving adherence to the Mediterranean diet may have a beneficial impact on the activity of axSpA. Patients with a lower BMI and older patients are less prone to modify their diet towards the Mediterranean diet following nutritional advice. Patients with psoriasis may have a limited benefit from dietary improvement., Study Registration: Protocol No. 52723, Padova Hospital Medical Ethical Committee (October 11, 2010)., (© 2021.

Mud-bath therapy (MBT) has been used as a treatment for rheumatic diseases and musculoskeletal complaints in the Euganean Thermal Area (near Padova, Italy) since ancient time. There is no consensus about the use of MBT in patients with inflammatory rheumatic diseases, although experimental studies have suggested a beneficial effect of MBT on chronic articular inflammation. To evaluate the effects of MBT in patients affected by seronegative spondyloarthritis, very common chronic inflammatory rheumatic diseases, randomized controlled trials (RCT) performed in the Euganean Thermal Area have been reviewed. A significant improvement of spondylitis parameters was observed in enteropathic spondylitis, without bowel symptom exacerbation. A long-term amelioration of clinical evaluation indices was found in ankylosing spondylitis. A significant improvement of cutaneous lesions, arthritis activity, and patient's functional ability was observed in psoriatic arthritis. MBT was usually well tolerated and adverse side effects were rarely reported. The review of the RCT suggests that MBT may exert additional beneficial effects in patients with seronegative spondyloarthritis treated with pharmacological therapy.
