ABSTRACT
BACKGROUND: Since the development of the OMERACT Systemic Lupus Erythematosus (SLE) Core Outcome Set (COS) in 1998, many new SLE domains have been identified and measures developed, creating a need to update the SLE COS. To revisit the 1998 SLE COS and research agenda domains, and generate new candidate domains, we conducted this study of patients with SLE and collaborators. OBJECTIVE: (1) To evaluate existing candidate SLE domains for inclusion in the SLE COS. (2) To generate additional candidate SLE domains for COS consideration. (3) To engage SLE collaborators, including patients, in developing the updated SLE COS. METHODS: The OMERACT SLE Working Group's steering committee developed a survey to assess the importance of candidate SLE domains and generate additional domains for consideration towards the SLE COS. Patients with SLE followed at the University of Toronto Lupus Clinic (patient group) and members of the OMERACT SLE Working Group (collaborator group) were invited to complete the survey between August 2022 and February 2023. RESULTS: A total of 175 patients were invited and 100 completed the survey. Of 178 collaborators invited, 145 completed the survey. Patients tended to prioritize life-impact domains while collaborators prioritized clinical domains. Both patients and collaborators recommended additional domains to those included in the 1998 SLE COS and research agenda. CONCLUSION: The domain inclusion and importance results demonstrate that patients and collaborators prioritize different domains, so capturing the perspectives of both groups is essential to ensure a holistic assessment of SLE. The results of the study identify domains that already have a high level of agreement for potential inclusion in the SLE COS, domains that require further explanation, and novel domains that warrant consideration.
ABSTRACT
The ß-catenin dependent canonical Wnt signaling pathway plays a crucial role in maintaining normal homeostasis. However, when dysregulated, Wnt signaling is closely associated with various pathological conditions, including inflammation and different types of cancer.Here, we show a new connection between the leukocyte inflammatory response and the Wnt signaling pathway. Specifically, we demonstrate that circulating human primary monocytes express distinct Wnt signaling components and are susceptible to stimulation by the classical Wnt ligand-Wnt-3a. Although this stimulation increased the levels of ß-catenin protein, the expression of the classical Wnt-target genes was not affected. Intriguingly, treating circulating human monocytes with Wnt-3a induces the secretion of cytokines and chemokines, enhancing monocyte migration. Mechanistically, the enhanced monocyte migration in response to Wnt stimuli is mediated through CCL2, a strong monocyte-chemoattractant.To further explore the physiological relevance of these findings, we conducted ex-vivo experiments using blood samples of patients with rheumatic joint diseases (RJD) - conditions where monocytes are known to be dysfunctional. Wnt-3a generated a unique cytokine expression profile, which was significantly distinct from that observed in monocytes obtained from healthy donors.Thus, our results provide the first evidence that Wnt-3a may serve as a potent stimulator of monocyte-driven immune processes. These findings contribute to our understanding of inflammatory diseases and, more importantly, shed light on the role of a core signaling pathway in the circulation.

BACKGROUND: The Outcome Measures in Rheumatology (OMERACT) Systemic Lupus Erythematosus (SLE) Working Group held a Special Interest Group (SIG) at the OMERACT 2023 conference in Colorado Springs where SLE collaborators reviewed domain sub-themes generated through qualitative research and literature review. OBJECTIVE: The objective of the SIG and the subsequent meetings of the SLE Working Group was to begin the winnowing and binning of candidate domain sub-themes into a preliminary list of candidate domains that will proceed to the consensus Delphi exercise for the SLE COS. METHODS: Four breakout groups at the SLE SIG in Colorado Springs winnowed and binned 132 domain sub-themes into candidate domains, which was continued with a series of virtual meetings by an advisory group of SLE patient research partners (PRPs), members of the OMERACT SLE Working Group Steering Committee, and other collaborators. RESULTS: The 132 domain sub-themes were reduced to a preliminary list of 20 candidate domains based on their clinical and research relevance for clinical trials and research studies. CONCLUSION: A meaningful and substantial winnowing and binning of candidate domains for the SLE COS was achieved resulting in a preliminary list of 20 candidate domains.

Objective: We aimed to characterize the course of COVID-19 in autoimmune inflammatory rheumatic disease (AIIRD) patients in Israel, taking into consideration several remarkable aspects, including the outcomes of the different outbreaks, the effect of vaccination campaigns, and AIIRD activity post-recovery. Methods: We established a national registry of AIIRD patients diagnosed with COVID-19, including demographic data, AIIRD diagnosis, duration and systemic involvement, comorbidities, date of COVID-19 diagnosis, clinical course, and dates of vaccinations. COVID-19 was diagnosed by a positive SARS-CoV-2 polymerase chain reaction. Results: Israel experienced 4 outbreaks of COVID-19 until 30.11.2021. The first three outbreaks (1.3.2020 - 30.4.2021) comprised 298 AIIRD patients. 64.9% had a mild disease and 24.2% had a severe course; 161 (53.3%) patients were hospitalized, 27 (8.9%) died. The 4th outbreak (delta variant), starting 6 months after the beginning of the vaccination campaign comprised 110 patients. Despite similar demographic and clinical characteristics, a smaller proportion of AIIRD patients had negative outcomes as compared to the first 3 outbreaks, with regards to severity (16 patients,14.5%), hospitalization (29 patients, 26.4%) and death (7 patients, 6.4%). COVID-19 did not seem to influence the AIIRD activity 1-3 months post-recovery. Conclusions: COVID-19 is more severe and has an increased mortality in active AIIRD patients with systemic involvement, older age and comorbidities. Vaccination with 3 doses of the mRNA vaccine against SARS-CoV-2 protected from severe COVID-19, hospitalization and death during the 4th outbreak. The pattern of spread of COVID-19 in AIIRD patients was similar to the general population.

OBJECTIVE: Screening for cognitive impairment (CI) in systemic lupus erythematosus (SLE) relies on the American College of Rheumatology (ACR) neuropsychological battery (NB). By studying the concurrent criterion validity, our goal was to assess the Montreal Cognitive Assessment (MoCA) as a screening tool for CI compared to the ACR-NB and to evaluate the added value of the MoCA to the Automated Neuropsychological Assessment Metrics (ANAM). METHODS: A total of 285 adult SLE patients were administered the ACR-NB, MoCA, and ANAM. For the ACR-NB, patients were classified as having CI if there was a Z score of ≤-1.5 in ≥2 domains. The area under the curve (AUC) and sensitivities/specificities were determined. A discriminant function analysis was applied to assess the ability of the MoCA to differentiate between CI, undetermined CI, and non-CI patients. RESULTS: CI was not accurately identified by the MoCA compared to the ACR-NB (AUC of 0.66). Sensitivity and specificity were poor at 50% and 69%, respectively, for the cutoff of 26, and 80% and 45%, respectively, for the cutoff of 28. The MoCA had a low ability to identify CI status. The addition of the MoCA to the ANAM led to improvement on the AUC by only 2.5%. CONCLUSION: The MoCA does not have adequate concurrent criterion validity to accurately identify CI in patients with SLE. The low specificity of the MoCA may lead to overdiagnosis and concern among patients. Adding the MoCA to the ANAM does not substantially improve the accuracy of the ANAM. These results do not support using the MoCA as a screening tool for CI in patients with SLE.

Prolonged steroid treatment has a suppressive effect on the immune system, however, its effect on the cellular response to mRNA vaccine is unknown. Here we assessed the impact of prolonged steroid treatment on the T-cell and humoral response to the SARS-CoV-2 spike (S) peptide following the third dose of the BNT162b2 vaccine in systemic autoimmune rheumatic disease patients. We found that CD4 T-cell response to the S peptide in patients on high-dose long-term steroid treatment showed significantly less S-peptide specific response, compare to low-dose or untreated patients. Remarkably, these results were not reflected in their humoral response, since almost all patients in the cohort had sufficient antibody levels. Moreover, S-peptide activation failed to induce significant mRNA levels of IFNγ and TNFα in patients receiving high-dose steroids. RNA-sequencing datasets analysis implies that steroid treatments' inhibitory effect of nuclear factor kappa-B signaling may interfere with the activation of S-specific CD4 T-cells. This reveals that high-dose steroid treatment inhibits T-cell response to the mRNA vaccine, despite having sufficient antibody levels. Since T-cell immunity is a crucial factor in the immune response to viruses, our findings highlight the need for enhancing the efficiency of vaccines in immune-suppressive patients, by modulation of the T-cell response.

BACKGROUND: The COVID-19 outbreak has led to the rapid development and administration of the COVID-19 vaccines worldwide. Data about the immunogenicity and adverse effects of the vaccine on patients with systemic autoimmune rheumatic diseases (SARDs) is emerging. AIM: To evaluate Pfizer/BioNTech (BNT162b2) mRNA-based vaccine second-dose immunogenicity and safety, and the relation between them, in patients with SARDs. METHODS: A total of one hundred forty tow adults who received two doses of the BNT162b2 vaccine were included in the study. The SARDs group included Ninety-nine patients and the control group (forty-three participants) comprised a mixture of healthy participants and patients who were seen at the rheumatology clinic for non-SARDs. Anti-SARS-CoV-2 IgG antibodies against the Spike protein were evaluated using a SARS-CoV-2 IgG immunoassay. A level of > 150 AU/mL was considered positive. An adverse effects questionnaire was given to the participants upon their first visit to the clinic after their BNT162b2 vaccination. RESULTS: Of the 142 participants, 116 were seropositive (81.7%) and 26 (18.3%) were seronegative. Of the seronegative participants, 96.2% were SARDs patients. The proportion of seropositivity in the SARDs patients treated with any immunosuppressant was significantly lower (69.9%) compared to the control group and SARDs patients not receiving immunosuppressants (96.8%). A significant negative correlation between seronegativity and treatment with rituximab, mycophenolate mofetil (MMF), and prednisone was found in the SARDs group (p = 0.004, 0.044, 0.007 respectively). No fever was observed following the BNT162b2 vaccine in seronegative patients, and the frequency of musculoskeletal adverse effects upon the second dose of the BNT162b2 vaccine was significantly higher in seropositive compared to seronegative patients and in the control group compared to the SARDs patients (p = 0.045, p = 0.02 respectively). CONCLUSION: A decline in the immunogenicity to the second dose of BNT162b2 mRNA is seen in patients with SARDs, especially in patients treated with rituximab, MMF, and prednisone. Adverse effects of the vaccine including fever and musculoskeletal symptoms might be a signal for the acquisition of immunity in those patients. KEY POINTS: ⢠BNT162b2 mRNA vaccine is less immunogenic in SARDs patients compared to the control group. ⢠Rituximab, prednisone, and mycophenolate mofetil significantly reduced immunogenicity to the vaccine. ⢠There is a correlation between immunogenicity and adverse effects of the vaccine.

Systemic lupus erythematosus (SLE) is a multisystem chronic autoimmune disease with variable clinical manifestations. Neuropsychiatric systemic lupus erythematosus (NPSLE) includes the neurologic syndromes of the central, peripheral and autonomic nervous system and the psychiatric syndromes observed in patients with SLE. Neuropsychiatric systemic lupus erythematosus events may present as an initial manifestation of SLE or may be diagnosed later in the course of the disease. Older adults with NPLSE include those who are ageing with known SLE and those with late-onset SLE. The diagnosis of NPSLE across the lifespan continues to be hampered by the lack of sensitive and specific laboratory and imaging biomarkers. In this review, we discuss the particular complexity of NPSLE diagnosis and management in older adults. We first discuss the epidemiology of late-onset NPSLE, then review principles of diagnosis of NPSLE, highlighting issues that are pertinent to older adults and that make diagnosis and attribution more challenging, such as atypical disease presentation, higher medical comorbidity, and differences in neuroimaging and autoantibody investigations. We also discuss clinical issues that are of particular relevance to older adults that have a high degree of overlap with SLE, including drug-induced lupus, cerebrovascular disease and neurocognitive disorders. Finally, we review the management of NPSLE, mainly moderate to high- dose glucocorticoids and immunosuppressants, again highlighting considerations for older adults, such as increased medication (especially glucocorticoids) adverse effects, ageing-related pharmacokinetic changes that can affect SLE medication management, medication dosing and attention to medical comorbidities affecting brain health.

BACKGROUND: The evaluation of Patient Reported Outcomes Measurement Information System (PROMIS) computerized adaptive test (CAT) in adults with systemic lupus erythematous (SLE) is an emerging field of research. We aimed to examine the test-retest reliability and construct validity of the PROMIS CAT in a Canadian cohort of patients with SLE. METHODS: Two hundred twenty-seven patients completed 14 domains of PROMIS CAT and seven legacy instruments during their clinical visits. Test-retest reliability of PROMIS was evaluated 7-10 days from baseline using intraclass correlation coefficient (ICC (2; 1)). The construct validity of the PROMIS CAT domains was evaluated against the commonly used legacy instruments, and also in comparison to disease activity and disease damage using Spearman correlations. A multitrait-multimethod matrix (MMM) approach was used to further assess construct validity comparing selected 10 domains of PROMIS and SF-36 domains. RESULTS: Moderate to excellent reliability was found for all domains (ICC [2;1] ranging from lowest, 0.66 for Sleep Disturbance and highest, 0.93 for the Mobility domain). Comparing seven legacy instruments with 14 domains of PROMIS CAT, moderate to strong correlations (0.51-0.91) were identified. The average time to complete all PROMIS CAT domains was 11.7 min. The MMM further established construct validity by showing moderate to strong correlations (0.55-0.87) between select PROMIS and SF-36 domains; the average correlations from similar traits (convergent validity) were significantly greater than the average correlations from different traits. CONCLUSIONS: These results provide evidence on the reliability and validity of PROMIS CAT in SLE in a Canadian cohort.

INTRODUCTION: Intravenous immunoglobulin (IVIg) is currently used with considerable success for the treatment of many autoimmune diseases, including systemic lupus erythematosus (SLE). Among its various indications, IVIg has also been found to be beneficial in myocarditis, whether or not it is associated with an autoimmune disease. Nevertheless, data regarding IVIg treatment for myocarditis/cardiomyopathy in patients with SLE are sparse. The objective of this case series was to describe our experience with IVIg as a treatment for lupus myocarditis and to review the literature for IVIg for this indication. PATIENT CONCERNS: We report 5 female patients with SLE, who presented with signs of acute heart failure including pulmonary congestion and arrhythmias. DIAGNOSIS: Echocardiography demonstrated new reduced left ventricular ejection fraction of 20% to 30%. Two patients underwent coronary artery angiography, which demonstrated normal coronary arteries, supporting the diagnosis of myocarditis or nonischemic cardiomyopathy. INTERVENTIONS: High-dose IVIg treatment was initiated in all 5 patients. OUTCOMES: Following the treatment, clinical and echocardiographic improvement in cardiac function occurred within a few days to 1âmonth. This dramatic improvement persisted for several years. CONCLUSION: Based on our case series, we believe that IVIg has an important role in the management of lupus acute cardiomyopathy. This safe, well-tolerated optional treatment should be considered, especially in severe cases.

BACKGROUND: SLE is an independent risk factor for cardiovascular disease (CVD). This study aimed to determine which among QRISK2, QRISK3, Framingham Risk Score (FRS), modified Framingham Risk Score (mFRS) and SLE Cardiovascular Risk Equation (SLECRE) best predicts CVD. METHODS: This is a single-centre analysis on 1887 patients with SLE followed prospectively according to a standard protocol. Tools' scores were evaluated against CVD development at/within 10 years for patients with CVD and without CVD. For patients with CVD, the index date for risk score calculation was chosen as close to 10 years prior to CVD event. For patients without CVD, risk scores were calculated as close to 10 years prior to the most recent clinic appointment. Proportions of low-risk (<10%), intermediate-risk (10%-20%) and high-risk (>20%) patients for developing CVD according to each tool were determined, allowing sensitivity, specificity, positive/negative predictive value and concordance (c) statistics analysis. RESULTS: Among 1887 patients, 232 CVD events occurred. QRISK2 and FRS, and QRISK3 and mFRS, performed similarly. SLECRE classified the highest number of patients as intermediate and high risk. Sensitivities and specificities were 19% and 93% for QRISK2, 22% and 93% for FRS, 46% and 83% for mFRS, 47% and 78% for QRISK3, and 61% and 64% for SLECRE. Tools were similar in negative predictive value, ranging from 89% (QRISK2) to 92% (SLECRE). FRS and mFRS had the greatest c-statistics (0.73), while QRISK3 and SLECRE had the lowest (0. 67). CONCLUSION: mFRS was superior to FRS and was not outperformed by the QRISK tools. SLECRE had the highest sensitivity but the lowest specificity. mFRS is an SLE-adjusted practical tool with a simple, intuitive scoring system reasonably appropriate for ambulatory settings, with more research needed to develop more accurate CVD risk prediction tools in this population.

RATIONALE: Eosinophilic fasciitis (EF) is an uncommon connective tissue disorder characterized by limb and trunk erythema, with symmetrical thickening of the skin. Its pathogenesis is poorly understood. Treatment consists mainly of glucocorticoids. Yet, no randomized trials have evaluated therapies for this rare disease and the optimal treatment modality remains unclear. Although most patients show partial or complete response to glucocorticoids, many relapse upon drug tapering, while others either do not respond at all or fail to sustain prolonged remission. Second-line therapy for this rare disorder includes mainly methotrexate (MTX), azathioprine, cyclosporine and hydroxychloroquine. Recently, several attempts using rituximab and intravenous immunoglobulins (IVIG) have shown good clinical results. PATIENT CONCERNS: The three patients had good clinical response to glucocorticoid treatment, followed by disease flare when the drug dose was tapered. Adding methotrexate in all patients and azathioprine to patient 3 did not lead to remission. DIAGNOSES: EF was diagnosed in all patients based on clinical presentation accompanied by fascia biopsy that demonstrated eosinophilic fasciitis. INTERVENTIONS: The patients were successfully treated with rituximab or IVIG, achieving sustained remission. OUTCOMES: The three cases had good clinical response to glucocorticoid treatment, followed by disease flare when the drug dose was tapered. The patients were then successfully treated with rituximab or IVIG, achieving sustained remission. LESSONS: This review of three cases of EF supports the results of previous reports, suggesting addition of rituximab and IVIG is an effective treatment for patients with refractory disease.

OBJECTIVES: To study the clinical phenotypes, determined based on cumulative disease activity manifestations, and sociodemographic factors associated with depression and anxiety in SLE. METHODS: Patients attending a single centre were assessed for depression and anxiety. SLE clinical phenotypes were based on the organ systems of cumulative 10-year SLE Disease Activity Index 2000 (SLEDAI-2K), prior to visit. Multivariable logistic regression analyses for depression, anxiety, and coexisting anxiety and depression were performed to study associated SLE clinical phenotypes and other factors. RESULTS: Among 341 patients, the prevalence of anxiety and depression was 34% and 27%, respectively, while 21% had coexisting anxiety and depression. Patients with skin involvement had significantly higher likelihood of anxiety compared with patients with no skin involvement [adjusted odds ratio (aOR) = 1.8; 95% CI: 1.1, 3.0]. Patients with skin involvement also had higher likelihood of having coexisting anxiety and depression (aOR = 2.0, 95% CI: 1.2, 3.9). Patients with musculoskeletal (MSK) (aOR = 1.9; 95% CI: 1.1, 3.5) and skin system (aOR = 1.8; 95% CI: 1.04, 3.2) involvement had higher likelihood of depression compared with patients without skin or musculoskeletal involvement. Employment status and fibromyalgia at the time of the visit, and inception status were significantly associated with anxiety, depression, and coexisting anxiety and depression, respectively. CONCLUSION: SLE clinical phenotypes, specifically skin or MSK systems, along with fibromyalgia, employment and shorter disease duration were associated with anxiety or depression. Routine patient screening, especially among patients with shorter disease duration, for these associations may facilitate the diagnosis of these mental health disorders, and allow for more timely diagnosis.

OBJECTIVE: Screening for cognitive impairment in systemic lupus erythematosus (SLE) conventionally relies on the American College of Rheumatology (ACR) neuropsychologic battery (NB), which is not universally available. To develop a more accessible screening approach, we assessed validity of the Automated Neuropsychological Assessment Metrics (ANAM). Using the ACR NB as the gold standard for cognitive impairment classification, the objectives were 1) to measure overall discriminative validity of the ANAM for cognitive impairment versus no cognitive impairment, 2) to identify ANAM subtests and scores that best differentiate patients with cognitive impairment from those with no cognitive impairment, and 3) to derive ANAM composite indices and cutoffs. METHODS: A total of 211 consecutive adult patients, female and male, with SLE were administered the ANAM and ACR NB. 1) For overall discriminative validity of the ANAM, we compared patients with cognitive impairment versus those with no cognitive impairment on 4 scores. 2) Six ANAM models using different scores were developed, and the most discriminatory subtests were selected using logistic regression analyses. The area under the receiver operating characteristic curve (AUC) was calculated to establish ANAM validity against the ACR NB. 3) ANAM composite indices and cutoffs were derived for the best models, and sensitivities and specificities were calculated. RESULTS: Patients with no cognitive impairment performed better on most ANAM subtests, supporting ANAM's discriminative validity. Cognitive impairment could be accurately identified by selected ANAM subtests with top models, demonstrating excellent AUCs of 81% and 84%. Derived composite indices and cutoffs demonstrated sensitivity of 78-80% and specificity of 70%. CONCLUSION: This study provides support for ANAM's discriminative validity for cognitive impairment and utility for cognitive screening in adult SLE. Derived composite indices and cutoffs enhance clinical applicability.

INTRODUCTION: Cutaneous lupus erythematosus (CLE) encompasses a spectrum of dermatologic manifestations which can occur with or without systemic lupus erythematosus (SLE). Treatment of CLE is challenging as the traditional treatments are off label and often fail and there is no drug specifically approved for CLE. The knowledge gained from the emerging trials on biologic therapy in SLE has provided insight into the utility of biologic therapy for CLE. AREAS COVERED: An overview is provided on the biological agents studied for CLE discussing their immunological target, their efficacy in treating the various CLE manifestations and the outcome measures used. EXPERT OPINION: There is a paucity of trials dedicated to the biologic treatment of CLE. Several of the described biological treatments' efficacy suggests that different clinical phenotypes of CLE may require different immunological targeted therapies. Recently published and ongoing trials of SLE focusing on novel agents for CLE using the Cutaneous Lupus Area and Severity Index (CLASI) as the outcome measure have shown promising results. Further trials designed specifically to study the efficacy of biologic treatment in CLE subgroups with or without systemic involvement using specific metrics for assessing cutaneous involvement are needed and will aid in illuminating the role of biologic therapy in CLE.

INTRODUCTION: There are insufficient data on the aetiologic factors underlying splenic infarction (SI). Therefore, there is no consensus regarding the appropriate diagnostic approach. METHODS: We conducted a retrospective analysis of all patients admitted with SI from January 2004 to December 2014. Medical records were screened for the clinical presentation, underlying causes, associated medical conditions and methods of patient evaluation. RESULTS: We found 89 subjects with 90 episodes of SI. Presentation of SI was characterized by abdominal, flank and chest pain (82.2%, 18.9%, 7.8%, respectively); leukocytosis (in 67% of tested subjects); elevated LDH (72%), CRP (97.5%) and D-Dimer (100%). The main underlying mechanisms were cardioembolic (54.4%), vascular (20%), haematologic disorders (15.6%) and multiple causes (21.1%). Atrial fibrillation and atherosclerosis were common in older patients (age > 70 years) while antiphospholipid syndrome occurred exclusively in younger individuals. SI was the presentation of previously unknown medical conditions in 38% of patients. Abdominal CT, ECG, echocardiography and blood cultures demonstrated the highest diagnostic yield. CONCLUSIONS: Contributing factors are identified in the majority of SI patients. We recommend CT, ECG, echocardiography and blood cultures in all cases. Atrial fibrillation should be sought in older patients, while APLS and haematologic disorders should be suspected in younger ones. KEY MESSAGES There is no consensus regarding the diagnostic approach and management of splenic infarction. Cardiovascular disease and atrial fibrillation are the main causes for SI in elderly subjects while hematological, infectious and other causes are more prevalent in younger ones. Our data strongly suggests a high diagnostic yield for CT scan, ECG, blood culture and echocardiogram in every patient with SI.

BACKGROUND: Physical inactivity is a pivotal factor in the development and progression of various chronic diseases. However, most fitness facilities exclude unhealthy individuals. Therefore, an exercise program that admits such patients is imperative. OBJECTIVES: To evaluate the effectiveness of a fitness facility that admits adult subjects with multiple chronic diseases. METHODS: We conducted a retrospective screening of patient records from the Medical Fitness Facility at Meir Medical Center, Israel. Intake of subjects was done by a multidisciplinary team. For each individual, personalized diet and exercise plans were developed and patients attended the facility twice a week. Each participant was evaluated at enrolment and after 4 months for well-being, metabolic parameters, exercise capacity, and laboratory blood tests. RESULTS: A total of 838 individuals were enrolled, mean age 57 years. Their medical conditions included dyslipidemia (48.8%), hypertension (37.6%), and diabetes mellitus (24.9%), followed by musculoskeletal problems (arthropathy 19%, lower back pain 16.1%) and ischemic heart disease (13.4%). Less common diagnoses were vascular diseases, pulmonary diseases, and malignancy. Only 40.5% of participants adhered to the regimen with advanced age being the best predictor for adherence. At the follow-up visit, body mass index was lower (31.2 vs. 30.2 kg/m2, P <0.0001), exercise capacity increased (measured as maximal MET; 7.1 vs. 8.1, P < 0.0001), and well-being improved (measured by Short Form Survey [SF-36]; 69.3 vs. 76.0, P <0.0001). CONCLUSIONS: We show that a fitness program for patients with multiple chronic diseases is feasible and effective in improving prognostic parameters, albeit significantly challenged by adherence limitations.
