Outcomes in progressive systemic sclerosis treated with autologous hematopoietic stem cell transplantation compared with combination therapy.

OBJECTIVES: Autologous hematopoietic stem cell transplantation (AHSCT) has been shown to improve long-term survival for early diffuse progressive systemic sclerosis (SSc) compared with cyclophosphamide. Cyclophosphamide, however, does not provide a long-term benefit in SSc. The combination of mycophenolate mofetil (MMF) and rituximab is a potent alternative regimen. We aimed to retrospectively compare the outcomes of SSc patients who underwent AHSCT to patients who met the eligibility criteria for AHSCT but received upfront combination therapy with MMF and rituximab. METHODS: Repeated assessments of modified Rodnan Skin Score (mRSS), forced vital capacity (FVC), and diffusing capacity (DLCO) values were conducted. Clinical improvement was defined as an mRSS decrease > 25% or an FVC increase > 10%. Event-free survival (EFS) was defined in the absence of persistent major organ failure or death. RESULTS: Twenty-one SSc patients in the combination therapy group were compared with sixteen in the AHSCT group. Age, sex and disease duration were similar between the two groups. Clinical improvement at 12 months was seen in 18 (86%) patients in the combination group compared with 13 (81%) in the AHSCT group (p= 0.7). The hazard ratio for EFS at 24 months favored the combination group (HR = 0.09, P= 0.04). During follow-up, both groups exhibited a significant and comparable reduction in mRSS and an increase in FVC values at each time interval up to 24 months. CONCLUSION: MMF and rituximab compared with AHSCT in SSc patients eligible for AHSCT resulted in similar skin and lung clinical improvement with a better safety profile at 24 months.

A deep look into the storm: Israeli multi-center experience of coronavirus disease 2019 (COVID-19) in patients with autoimmune inflammatory rheumatic diseases before and after vaccinations.

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.

Normotensive scleroderma renal crisis as the presenting symptom of systemic sclerosis sine scleroderma: A case report.

Scleroderma renal crisis is a rare but serious complication of systemic sclerosis. It is usually associated with marked hypertension and carries significant risk for morbidity and mortality. Its occurrence prior to the development of skin sclerosis is exceedingly rare. We report a case of a patient who presented with recurrent pericardial effusion and later tested positive for anti-nuclear and anti-topoisomerase antibodies. He later developed normotensive renal crisis as confirmed by kidney biopsy despite complete absence of skin involvement. To our knowledge, this is the first published case of a patient presenting with normotensive renal crisis without any skin involvement.

The association between elevated serum interleukin-22 and the clinical diagnosis of axial spondyloarthritis: A retrospective study.

OBJECTIVE: There is an unmet need for a reliable biomarker for the differentiation of axial spondyloarthritis (AxSpA) from its mimickers. Serum levels of interleukin-22 (IL-22) have previously been found to be significantly elevated in patients with AxSpA compared with healthy individuals or persons with osteoarthritis. METHODS: Consecutive patients with established or suspected AxSpA were enrolled. The clinical data, as well as results of laboratory and imaging studies, were acquired from patients' charts. The final diagnosis of definite or probable SpA, or an alternative diagnosis, was determined, and the serum levels of IL-22 were examined by enzyme-linked immunosorbent immunoassay. RESULTS: Interleukin-22 levels were significantly higher in patients with definite AxSpA (29 patients) compared with patients with alternative diagnoses (14 patients) and healthy volunteers (16 individuals; P < 0.001 for both comparisons). The sensitivity and specificity of the serum IL-22 for the AxSpA diagnosis were 0.68 (95% CI 0.49-0.84) and 0.86 (95% CI 0.68-0.95), respectively, for the cut-off value of 5 pg/mL. In patients with AxSpA, serum IL-22 levels did not correlate with modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score (ASDAS), or serum C-reactive protein. CONCLUSION: Serum IL-22 levels are elevated in patients with the clinical diagnosis of AxSpA and can potentially serve as an independent biomarker for the differentiation of AxSpA from its non-inflammatory mimickers.

Vascular Reactivity of Adult-Onset Systemic Lupus Erythematosus Patients.

BACKGROUND: Cardiovascular disease (CVD) is more frequent in patients with systemic lupus erythematosus (SLE) compared with age- and sex-matched healthy subjects. SLE is an autoimmune disease that is more prevalent in women (9:1). Women tend to develop CVD in post-menopausal years; however, women with SLE may develop endothelial dysfunction and CVD at a younger age in the pre-menopausal years. OBJECTIVES: To study the endothelial function of adult-onset SLE patients from the north of Israel (the Galilee region) and to determine whether modern management (including biological treatments) changes the risk of developing CVD. METHODS: Thirteen females with adult-onset SLE without renal involvement were recruited to this prospective study. Clinical parameters (age, height, body mass index [BMI]), laboratory parameters (C-reactive protein [CRP] and hemoglobin level), and vascular responsiveness (flow mediated diameter percent change [FMD%]) were evaluated and compared to 11 age-matched healthy females. Student's t-test was used to find differences between the two groups. RESULTS: No difference was observed in adult-onset SLE female patients and their age- and sex-matched controls with regard to age (42.1 ± 11.8 years vs. 36.6 ± 10.8 years, P = NS), BMI (25 ± 1.8 kg/m2 vs. 25 ± 2.5 kg/m2, P = NS), and hemoglobin level (11.9 ± 0.9 gr% vs. 12.7 ± 1.2 gr%, P = NS). However, a significant difference was found in CRP (2.57 ± 2.2 mg vs. 0.60 ± 0.37 mg, P = 0.001), vascular responsiveness (0.94 ± 6.6 FMD% vs. 9.2 ± 8.1 FMD%, P = 0.012), and height (165.7 ± 4.5 cm vs. 171.6 ± 5.8 cm, P = 0.009). CONCLUSIONS: Adult-onset SLE females had impaired endothelial function even though they were treated by modern protocols.
