Background: The EULAR Sjögren's syndrome (SS) disease activity index (ESSDAI) pulmonary domain is used to assess the activity of respiratory system involvement in Sjögren's disease (SjD). The most unfavorable form of respiratory involvement in SjD, after lymphomas, is interstitial lung disease (ILD)., Objectives: The aim of the study was to assess the involvement of the respiratory system in SjD patients and the occurrence of ILD in high-resolution computed tomography (HRCT), depending on immunological markers, the influence of cigarette smoking, and the age of the patients., Design: Single-center, registry, cohort study., Methods: Among all SjD patients, a group with involvement in the pulmonary domain was distinguished. This group was later subjected to a detailed analysis of immunological and serological markers and chest imaging tests., Results: In all, 64 patients out of 299 with SjD had involvement in the pulmonary domain defined according to the ESSDAI definition. The most frequently reported clinical symptoms of respiratory system involvement included dryness and chronic cough (over 80% of patients), followed by shortness of breath. Nine percent of patients with changes in lungs were asymptomatic. Patients with pulmonary involvement were older (54 vs 48 years, p  < 0.05). In the subpopulation of patients with SjD and pulmonary involvement, the presence of rheumatoid factor (73% vs 60%, p  < 0.05), and hematological domain involvement according to ESSDAI (54% vs 37%, p  < 0.05) were more common. In the group of 64 patients with a positive pulmonary domain, 34 (53%) had ILD on HRCT. A higher incidence of comorbidities was found in the population of patients with ILD. No correlation was found between the type of lung involvement and the immunological profile, inflammatory markers, age, and smoking habit., Conclusion: Involvement of the pulmonary domain is common in patients with SjD. However, the clinical picture is very heterogeneous, which determines the subsequent personalization of treatment., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2024.)

The total number of confirmed cases of COVID-19 caused by SARS-CoV-2 virus infection is over 621 million. Post-COVID-19 syndrome, also known as long COVID or long-haul COVID, refers to a persistent condition where individuals experience symptoms and health issues after the acute phase of COVID-19. The aim of this study was to assess the strength and fatigue of skeletal muscles in people recovered from COVID-19. A total of 94 individuals took part in this cross-sectional study, with 45 participants (referred to as the Post-COVID Cohort, PCC) and 49 healthy age-matched volunteers (Healthy Control Cohort, HCC). This research article uses the direct dynamometry method to provide a detailed analysis of post-COVID survivors' strength and power characteristics. The Biodex System 4 Pro was utilized to evaluate muscle strength characteristics during the fatigue test. The fatigue work in extensors and flexors was significantly higher in the PCC. The PCC also showed significantly less power in both extensors and flexors compared to the HCC. In conclusion, this study provides compelling evidence of the impact of post-COVID-19 fatigue on muscle performance, highlighting the importance of considering these effects in the rehabilitation and care of individuals recovering from the virus. PCC achieved lower muscle strength values than HCC.

Introduction: The total number of confirmed cases of COVID-19 caused by the SARS-CoV-2 virus infection is over 621 million in the world. In approximately 63% of cases, the patient still experiences persistent symptoms 30 days after the onset of symptoms or hospitalisation, and 45.9% of patients have experienced or will experience symptoms for at least three months. Despite the prevalence of chronic symptoms and pathological changes that may affect gait and functional mobility in people with a history of COVID-19, there are few publications investigating the impact of these abnormalities. This study aims to determine the long-term effects of COVID-19 on gait and the Timed-Up and Go Task., Material and Methods: A total of 30 individuals took part in the experiment. The subjects in the study group were infected with the COVID-19 virus and required hospital treatment. Prior to the study, the subjects had no chronic diseases or other conditions affecting the musculoskeletal system. The non-infected by COVID-19 group was a healthy population with no history of COVID-19 disease. The study used the inertial system wireless motion analysis system based on 15 inertial sensors (inertial measurement units, IMUs). IMU sensors were placed on the following body segments: head, sternum, middle and lower spine, shoulder, arm, forearm, hand, shank, for the left and right limb. Movement task reports generated from the recording were created using myoRESEARCH 3.10. The subjects in the study group were asked to perform a movement task test-the Timed-Up and Go Test (TUG): sit-to-stand, walk (3 m) without change in direction, walk termination, and stand-to-sit., Results: It took 46% longer for those infected by COVID-19 (participants) to complete the entire movement task compared to those in the not-infected by COVID-19 group. Sit-to-Stand Time [s] was greater in the infected by COVID-19 group and was 2.1 ± 0.7. Mean Walking Speed [m/s] was lower than in the not-infected by COVID-19 group and was 0.26 ± 0.07. Walking cadence [steps/min] was lower and was 21.2 ± 1.2. Infected by COVID-19 participants achieved a smaller anterior pelvic tilt angle ( p < 0.001) and a smaller hip flexion angle ( p = 0.025), with an increase in knee ( p < 0.001) and ankle ( p < 0.001) flexion angles., Conclusions: Individuals in the infected by COVID-19 group present changes in the ranges of motion and the time to complete the TUG task, despite the fact that at least eight weeks passed after hospital discharge.

Introduction: This multicenter, real-world, retrospective cohort study aimed to assess the effectiveness and safety of tofacitinib (TOFA) in rheumatoid arthritis (RA)., Material and Methods: Two hundred nine patients with active RA treated with TOFA, unresponsive to at least 2 conventional synthetic disease-modifying drugs, were recruited. Clinical characteristics were extracted from an electronic registry and supplemented with manual chart review and data linkage with ambulatory care. Drug retention and reasons for discontinuation were evaluated., Results: Median (interquartile range) follow-up in the whole sample was 16.9 (5.93-31.7) months. Mean (standard deviation) age was 51.44 (±11.84) years, with female predominance ( n = 168, 80.4%). Only 30 patients (14.4%) had no pre-existing traditional cardiovascular (CV) risk factor at TOFA initiation. Tofacitinib retention rates were high, with median survival estimated at 89.3% at 6 months, 82.4% at 12 months, and 60.4% at 24 months. Ineffectiveness was the primary cause of discontinuation ( n = 50). The rate of adverse events (AEs) was relatively low, with lipid abnormalities, blood count alterations, and infectious events among the most common. No major adverse CV event was reported. The incidence rate of AEs necessitating treatment switch was 60.34 (95% CI: 37-92) per 1,000 person-years of follow-up. Presence of multiple (> 3) CV risk factors was associated with lower odds of TOFA retention and treatment effectiveness., Conclusions: Tofacitinib demonstrated high retention rates and a favorable safety profile in RA patients, including those with traditional CV risk factors. Tofacitinib may be a valuable treatment option for RA patients when combined with individualized CV risk management. Further studies are warranted to explore the long-term effects of TOFA and its CV impact in larger populations., Competing Interests: Karolina Palej, Kornelia Chmurzyńska, and Krzysztof Batko declare no conflict of interest., (Copyright: © 2023 Narodowy Instytut Geriatrii, Reumatologii i Rehabilitacji w Warszawie.)

Introduction: The aim was to detect subclinical structural retinal abnormalities in optical coherence tomography (OCT) in ophthalmologically asymptomatic systemic lupus erythematosus (SLE) patients without signs of lupus retinopathy or drug toxicity in fundus examination and in OCT and to assess the relationship between OCT parameters and disease activity, therapy type and burden on other organs to demonstrate the utility of OCT in early retinal impairment in SLE patients., Material and Methods: Cross-sectional study. Thirty-three SLE patients (57 eyes) and 31 healthy individuals (56 eyes) were enrolled in the study. We excluded patients with evidence of lupus retinopathy or hydroxychloroquine (HCQ) toxicity on OCT or fundus examination to reveal any subclinical changes. All patients underwent full ophthalmologic examination in the slit lamp including best corrected visual acuity, tonometry, and OCT. The Kolmogorov-Smirnov distribution test was used to assess the normal distribution in quantitative values. The differences between the individual measured parameters in the groups were analyzed using the Mann-Whitney U test. Spearman's rank correlation test was used to assess the correlation between the measured parameters and quantitative clinical data., Results: There was no difference in the OCT findings between SLE and healthy control groups. Among the study group a negative correlation was found between disease duration and age and retinal nerve fiber layer thickness in the inferior quadrant ( p = 0.0063, p = 0.0036). No correlations were observed between examined retinal parameters and duration of hydroxychloroquine therapy, hydroxychloroquine as well as chloroquine cumulative dose and disease activity indices., Conclusions: Optical coherence tomography is a widespread ophthalmic modality used for SLE retinopathy and HCQ toxicity screening. Our study did not demonstrate its clinical potency in diagnosis of subclinical retinal involvement. An optical coherence tomography device seems to be less sensitive in subclinical retinal impairment detection than optical coherence tomography angiography., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2023 Narodowy Instytut Geriatrii, Reumatologii i Rehabilitacji w Warszawie.)

A triad of symptoms characterises Felty's syndrome: seropositive rheumatoid arthritis (RA), splenomegaly and neutropenia. The treatment of Felty's syndrome is based on using classic synthetic and biological disease-modifying anti-rheumatic drugs (DMARDs). In this article, we present a case of a patient with Felty's syndrome who was treated with biologic treatment. A systematic search of the literature on the electronic medical database was conducted. The drugs from the DMARD group, despite reducing the activity of the disease, may cause significant clinical complications. It is important to know about the diagnosis, differentiation and treatment of neutropenia and the prevention of febrile neutropenia. The article discusses the current therapeutic possibilities using both classical and biologic DMARDs., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2023 Narodowy Instytut Geriatrii, Reumatologii i Rehabilitacji w Warszawie.)

Lupus retinopathy is the second most common eye involvement in systemic lupus erythematosus (SLE), associated with significant visual deterioration and well-known negative prognostic factor for survival. Ocular manifestation in SLE, relating the retina, ranges from asymptomatic vascular involvement to vision devastating vascular occlusions. Subclinical microvascular changes are undetectable in slit lamp examination, hence are underdiagnosed. Optical coherence tomography angiography (OCTA) is a novel, easy to interpret and non-invasive technique that allows retinal vessels visualization. OCTA simplifies clinical approach and measures the severity of decreased perfusion. The aim of the study was to demonstrate the retinal vascularization in a subclinical stage of ocular involvement in a cohort of SLE patients. Thirty-three patients (57 eyes) diagnosed with SLE were enrolled into the study group and 31 healthy individuals (56 eyes) into the control group. Vessel density reduction in parafovea, inferior and nasal quadrants of superficial retinal capillary plexus in a cohort of SLE patients was found. Among study group kidney involvement was associated with further microvasculature reduction. Knowing that retinal involvement may precede other organs impairment, early detection of retinal impairment and use of OCTA as a screening modality, may decrease overall disease morbidity.

Background: The COVID-GRAM is a clinical risk rating score for predicting the prognosis of hospitalized COVID-19 infected patients., Aim: Our study aimed to evaluate the use of the COVID-GRAM score in patients with COVID-19 based on the data from the COronavirus in the LOwer Silesia (COLOS) registry., Material and Methods: The study group (834 patients of Caucasian patients) was retrospectively divided into three arms according to the risk achieved on the COVID-GRAM score calculated at the time of hospital admission (between February 2020 and July 2021): low, medium, and high risk. The Omnibus chi-square test, Fisher test, and Welch ANOVA were used in the statistical analysis. Post-hoc analysis for continuous variables was performed using Tukey's correction with the Games-Howell test. Additionally, the ROC analysis was performed over time using inverse probability of censorship (IPCW) estimation. The GRAM-COVID score was estimated from the time-dependent area under the curve (AUC)., Results: Most patients (65%) had a low risk of complications on the COVID-GRAM scale. There were 113 patients in the high-risk group (13%). In the medium- and high-risk groups, comorbidities occurred statistically significantly more often, e.g., hypertension, diabetes, atrial fibrillation and flutter, heart failure, valvular disease, chronic kidney disease, and obstructive pulmonary disease (COPD), compared to low-risk tier subjects. These individuals were also patients with a higher incidence of neurological and cardiac complications in the past. Low saturation of oxygen values on admission, changes in C-reactive protein, leukocytosis, hyperglycemia, and procalcitonin level were associated with an increased risk of death during hospitalization. The troponin level was an independent mortality factor. A change from low to medium category reduced the overall survival probability by more than 8 times and from low to high by 25 times. The factor with the strongest impact on survival was the absence of other diseases. The medium-risk patient group was more likely to require dialysis during hospitalization. The need for antibiotics was more significant in the high-risk group on the GRAM score., Conclusion: The COVID-GRAM score corresponds well with total mortality. The factor with the strongest impact on survival was the absence of other diseases. The worst prognosis was for patients who were unconscious during admission. Patients with higher COVID-GRAM score were significantly less likely to return to full health during follow-up. There is a continuing need to develop reliable, easy-to-adopt tools for stratifying the course of SARS-CoV-2 infection.
