ABSTRACT
BACKGROUND: Anti-centromere antibodies, anti-topoisomerase-1 antibodies (ATA), and anti-RNA-polymerase III antibodies are three Systemic Sclerosis (SSc)-specific autoantibodies. Their detection is helpful in determining the prognosis. We aimed to evaluate whether ATA levels were associated with disease severity at diagnosis or disease progression during follow-up in ATA positive patients. METHODS: We conducted a single-centre French retrospective observational study, between 2014 and 2021. ATA positive patients fulfilling the ACR/EULAR 2013 classification criteria for SSc with a minimal follow-up of 1 year and 2 ATA dosages were included. SSc patients with high IgG ATA levels at baseline (>240IU/mL) were compared with SSc patients with low levels (≤240IU/mL), at inclusion and at 1 and 3 years. A variation of at least 30 % of ATA levels was considered significant. RESULTS: Fifty-nine SSc patients were included and analysed. There was a predominance of women and of patients with diffuse interstitial lung disease. Patients with high ATA levels exhibited a higher skin sclerosis assessed by the modified Rodnan skin score (P=0.0480). They had a lower carbon monoxide transfer coefficient (P=0.0457), a lower forced vital capacity (FVC) (P=0.0427) and more frequently had a FVC under 80 %, when compared to patients with low ATA levels (P=0.0423). Initial high ATA levels were associated with vascular progression at one year (21.95 % vs. 0 %; P=0.0495). CONCLUSION: ATA levels are associated with skin sclerosis and vascular progression in SSc. Beyond the detection of ATA, quantifying this autoantibody might be of interest in predicting disease severity and prognosis in SSc.

INTRODUCTION: Lymphadenopathies are a major cause of consultation in internal medicine, with various causes of diagnosis. Unexplained persistent lymphadenopathy must be biopsied to rule out malignant tumor. CASE REPORT: We report the case of a 53-year-old man, with inguinal lymphadenopathy evolving for more than one year. The patient had no associated symptoms and his blood tests were unremarkable. Due to the progression of the adenopathy and its hypermetabolism on PET-CT, an excisional biopsy was performed. Histological analysis revealed an intranodal proliferation of spindle cells with a palisading pattern. ß-catenine and smooth muscle actin labelling were positive, leading to the diagnosis of intranodal palisaded myofibroblastoma, a benign tumour. CONCLUSION: Intranodal palisaded myofibroblastoma is a rare benign cause of adenopathy, with often inguinal lymph node localization and slow growth and without risk of recurrence after surgical removal.

INTRODUCTION: Infections are associated with morbimortality of patients with giant cell arteritis (GCA). The aim of this work was twofold: the identification of factors predisposing to the risk of infection and the description of patients hospitalized with an infection occurring during the treatment period of CAG. METHODS: A monocentric retrospective study was conducted in GCA patients, comparing patients hospitalized for infection with patients without infection. The analysis included 21/144 (14.6%) patients with 26 infections (cases) and 42 control matched on sex, age, and diagnosis of GCA. RESULTS: Both groups were similar except for a higher frequency of seritis in cases (15% vs. 0%, p=0.03). Relapses of GCA were less common in cases (23.8% vs 50.0%, p=0.041). Hypogammaglobulinemia was present during infection. More than half of the infections (53.8%) occurred in the first year of follow-up with an average dose of 15mg/day of corticosteroids. Infections were mainly pulmonary (46.2%) and cutaneous (26.9%). CONCLUSION: Factors associated with infectious risk were identified. This preliminary monocentric work will continue with a national multicentre study.

BACKGROUND: Combining fat graft with platelet derived products is now common practice in regenerative surgery. We proposed to assess the safety and efficacy of Platelet-Rich Plasma (PRP) addition to a micro-lipofilling protocol for facial treatment of patients suffering from Systemic Sclerosis (SSc). OBJECTIVE: Main objective was to evaluate the improvement of the Mouth Handicap In Systemic Sclerosis (MHISS) scale score at 6 months post-therapy. METHOD: Included SSc patients had a MHISS score equal or up to 20. Surgery was performed under general anesthesia. Micro-fat and PRP (CCA-NA from DEPA Classification) were mixed in a 70/30 ratio, before injection in peri-oral sites according to a specific protocol. Efficacy criteria were recorded at baseline, 3 and 6 months. Moreover, we compared this cohort (current study) to a former (2015) non-enriched micro-lipofilling cohort in the same indication, using the same protocol. RESULTS: Thirteen women patients with mean age of 53.2 years (±14.3) have been included. At baseline, mean MHISS score was 29.5 (±8.7) and significantly decreased to 22.5 (±7.8) at 6 months (P=0.016), corresponding to a 22.0% of improvement from baseline, with a mean decrease of 6.5 points (±7.5) at 6 months. Patients received a mean volume of 30.8ml PRP-micro-fat (±8.1ml). CONCLUSION: PRP addition appeared beneficial, however, controlled studies are required to determine its superiority to facial micro-lipofilling.
