Management of comorbidities is essential to a patient-centered approach to the treatment of chronic inflammatory arthritis. The aim of this study was to compare the prevalence of comorbidities and their risk factors in rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) in a single center outpatient cohort. This cross-sectional study included adult patients diagnosed with RA, PsA, and axSpA from a single rheumatology outpatient center. Comorbidities were documented by physicians, and patients were categorized into two age groups, younger (< 45 years) and older (≥ 45 years), with age- and gender-based comparisons. Disease activity, comorbidities, and cardiovascular (CV) risk factors were analyzed using chi-squared tests for categorical variables and independent samples t-tests for continuous variables, with p values < 0.05 considered statistically significant. Comorbidities were registered by physicians using GoTreatIt® Rheuma software. Among 508 RA, 267 PsA, and 285 axSpA patients, the four most common comorbidities were hypertension (36.4%, 25.1%, and 19.7%, respectively), dyslipidemia (19.5%, 15.4%, 14.7% respectively), obesity (16.9%, 22.5%, 14% respectively) and thyroid disease (21.5%, 13.9%, 11.2% respectively). Other comorbidities differed among the diseases and included osteoporosis, osteoarthritis, diabetes mellitus, arrhythmia, and asthma in RA, diabetes mellitus, depression and asthma in PsA, osteoporosis and serious infection in axSpA. RA patients, compared to axSpA had a higher prevalence of coronary artery disease (4.1% vs. 0.7%, p = 0.006), arrhythmia (6.9% vs. 2.5%, p = 0.008) and major adverse cardiac events (2.6% vs. 0.4%, p = 0.024) compared to axSpA. Osteoporosis was more frequent in RA (19.1%) and axSpA (8.4%) than in PsA (2.3%; p < 0.001) and was frequently diagnosed in patients aged < 45. Depression prevalence was surprisingly low (1.6%, 5.2%, and 1.8%, respectively). RA patients had the highest multimorbidity rate, with 26.6% reporting three or more comorbidities, compared to 16.8% in PsA and 10.6% in axSpA (p < 0.001). Health status was poorest in RA and worse in women compared to men for all diseases. RA, PsA, and axSpA share the same four most common comorbidities: hypertension, dyslipidemia, obesity, and thyroid disease but have different prevalence of other disorders and CV risk factors, indicating the need for an individual screening and prevention approach. The possible unrecognition of depression should be evaluated.

Endothelial dysfunction (ED) is defined as an impairment in the vasodilatory, anti-thrombotic, and anti-inflammatory properties of the cells that make up the lining of blood vessels. ED is considered a key step in the development of atherosclerotic cardiovascular disease. The association between ED and systemic inflammatory diseases is well established. However, the prevalence and clinical significance of ED in psoriatic arthritis (PsA) have been investigated to a lesser extent. This review aims to explore the link between ED and PsA, including ED in macro- and microcirculation, as well as risk factors for its occurrence in PsA and its relationship with atherosclerosis in PsA. Furthermore, the ED in PsA was compared with that of rheumatoid arthritis (RA). Regarding ED in the microcirculation, the coronary flow reserve was found to be significantly reduced in individuals with PsA. The relationship between PsA and macrovascular ED is more pronounced, along with more advanced atherosclerosis detected in patients with PsA. These results are consistent with those obtained in RA studies. On the other hand, arterial stiffness and signs of vascular remodeling were found more frequently in RA than in PsA, with the potential role of efficient anti-TNF treatment in patients with PsA and psoriasis explaining this finding. The impact of ED on cardiovascular diseases and the burden of this risk caused independently by PsA have not yet been precisely established, however, this group of patients requires special attention with regard to cardiovascular events.

Background: Comorbidities are frequent in psoriatic arthritis (PsA) and may contribute to worse health-related outcomes. Patient-reported outcomes (PROs) are used to evaluate the burden of the assessed disease. The aim of this study is to evaluate the impact of comorbidities on selected PROs in PsA. Methods: Adult patients, diagnosed with PsA, based on CASPAR criteria, were included in this cross-sectional, observational study. Collected data encompassed the comorbidities and PROs (Health Assessment Questionnaire [HAQ], Multi-Dimensional Health Assessment Questionnaire [MDHAQ], 36-Item Short Form Health Survey [SF-36]). Standard statistic methods were performed for data assessment. Results: There were 267 participants included in the study (54.7% females). The most prevalent comorbidities were cardiovascular diseases (CVD) (29.2 %). Multimorbidity was observed in 50.2% cases and was associated with poorer results of SF-36 questionnaire, regarding bodily pain (34.7 [30.1, 39.3] vs. 47.5 [43.1, 52.0]; p<0.01), physical functioning (52.1 [47.3, 56.9] vs. 63.1 [58.9, 67.4]; p<0.01) and role physical (28.5 [21.2, 35.9] vs. 42.8 [35.2, 50.4]; p<0.01). CVD were associated with poorer MDHAQFn score (β=0.17, p<0.01), while mental disorders negatively influenced mental health (β= -0.35, p<0.01), vitality (β= -0.22, p<0.01), general health (β= -0.19, p<0.01), social functioning (β= -0.15, p=0.04) and role emotional (β= -0.30, p<0.01) dimensions of SF-36. Conclusions: Multimorbidity exerts significant impact on physical aspects of quality of life (QoL) in PsA. CVD and mental disorders adversely influence functional capacity as well as mental and social dimensions of QoL, respectively. The impact of comorbidities should be taken into account by clinicians and researchers assessing PROs.

Cel pracy: Wstęp: Fibromialgia (FM) często współwystępuje z zaburzeniami psychicznymi. Ponadto, kilka badan wskazuje, że zaburzenia psychiczne mogą być związane z nasileniem i wpływem FM. Celem naszej pracy było po pierwsze: ocenić różne wymiary objawów psychopatologicznych wśród pacjentów z FM i po drugie: zbadać zależności pomiędzy psychopatologią a odpowiedzią na leczenie inhibitorami wychwytu zwrotnego serotoniny i noradrenaliny (serotonin and noradrenaline reuptake inhibitors - SNRI).Metoda: Metoda: Niniejsze badanie przekrojowe przeprowadzono pomiędzy grudniem 2020 i listopadem 2022. Oporność na SNRI zdefiniowano jako <30% redukcję bólu po ≥8 tygodniach leczenia. Włączono 30 pacjentów z FM odpowiadających na SNRI (FM T[+]), 32 pacjentów nieodpowiadających na SNRI (FM T[-]) i 30 zdrowych ochotników. Uczestnicy byli badani przez lekarzy i wypełniali narzędzia samooceny mierzące poziom depresji (Krótki Inwentarz Symptomatologii Depresji, Szpitalna Skala Lęku i Depresji), lęku (inwentarz Stanu i Cechy Lęku), anhedonii (Skala Przyjemności Snatih’a-Hamiltona), dwubiegunowości (Kwestionariusz Zaburzeń Nastroju, Skala Hipomanii) i dysocjacji (Skala Doświadczeń Dysocjacyjnych - wersja poprawiona). Aby ocenić związki zmiennych psychopatologicznych i odpowiedzi na SNRI przeprowadzono analizy ANOVA i serię prostych regresji logistycznych.Wyniki: Wyniki: FM T[-] vs. FM T[+] ujawniali wyższy poziom depresji, cechy i stanu lęku, anhedonii i wyższe proporcje wyników wskazujących na obecność zaburzeń lękowych. Większe nasilenie depresji, lęku i anhedonii były predyktorami oporności na SNRI.Wnioski: Wnioski: Modyfikowalne objawy psychopatologiczne różnią pacjentów FM T[+] vs. FM[-] i są predyktorami oporności na SNRI. Ocena psychologiczna powinna być częścią standardowej opieki nad osobami z FM.

The rapid development of COVID-19 vaccines became essential for addressing the global pandemic. Reactive arthritis after vaccination has been a rare phenomenon. Here, we present a case series of three patients with joint inflammation possibly attributed to COVID-19 immunization (mRNA and live adenovirus vectored vaccine). Symptoms were alleviated using non-steroid anti-inflammatory drugs and glucocorticoids. After follow-up, the patients have not been diagnosed with any other rheumatic disease. Reactive arthritis after the COVID-19 vaccine is an unusual adverse effect and poses a negligible risk in comparison to the benefits of immunization, but it should be considered in differential diagnostics by a practicing rheumatologist who cares for patients with new-onset arthritis without apparent cause at the time of pandemic.

Tumour necrosis factor-α (TNF- α) antagonists are considered a significant therapeutic option in the treatment of sarcoidosis. Nevertheless, their use can also paradoxically result in sarcoidosis-like reactions. Here, we present a case of a 56-year-old patient with psoriatic arthritis who after 3 months of certolizumab therapy developed pulmonary sarcoidosis. Therefore, certolizumab was discontinued and prednisone initiated. Subsequently, 4 months later a complete remission of interstitial lesions was observed. Due to insufficient control of psoriatic arthritis, upadacitinib and methotrexate were prescribed and despite initial improvement, a couple of months later a massive exacerbation of skin psoriasis occurred and the treatment was switched to secukinumab. As of today, no evidence of sarcoidosis recurrence has been noted. Drug-induced sarcoidosis-like reactions (DISR) appear to be less frequently associated with certolizumab rather than with other anti-TNF-α agents. However, specific mechanisms of this phenomenon remain unclear and require future investigation.
