High prevalence of malnutrition in systemic sclerosis: Results from a French monocentric cross-sectional study.

OBJECTIVES: Systemic sclerosis (SSc) can cause malnutrition due to frequent gastrointestinal involvement. However, prevalence of malnutrition in SSc is poorly known. The aim of this study was to evaluate the prevalence of malnutrition in SSc and its potential associations with disease features in patients from a tertiary referral center. METHODS: All patients meeting American College of Rheumatology/European Alliance of Associations for Rheumatology criteria for SSc followed between January 1, 1985, and January 1, 2019, at the Department of Internal Medicine, Saint Eloi University Hospital, were included. Malnutrition was assessed using the 2020 French recommendations for SSc and the malnutrition universal screening tool score. Severe malnutrition was defined via the French Haute Autorité de Santé (National Health Authority) 2007 criteria. RESULTS: A total of 120 patients were included, with mean age 64 (± 15) y and a female-to-male sex ratio of 5:1. According to 2020 French recommendations, 71 patients (59.2%) were malnourished and 30 (25%) had at least one criterion of severe malnutrition. With the malnutrition universal screening tool score, 41.7%, 20%, and 38.3%, respectively, had low, medium, and high risk of malnutrition. Multivariate analysis revealed the following results: 1) malnutrition was associated with cardiac involvement (P < 0.01); 2) a high malnutrition universal screening tool score was also associated with specific cardiac involvement (P < 0.01); and 3) severe malnutrition was strongly correlated with interincisal distance <35 mm (P = 0.02). CONCLUSIONS: Malnutrition affects more than half of SSc patients and is associated with specific cardiac involvement. Interincisal distance <35 mm could be a red flag for severe malnutrition in SSc.

Prevalence of anti-neutrophil cytoplasmic antibody-associated vasculitis in the south of France, using the capture-recapture method.

OBJECTIVES: This study aimed to estimate the prevalence of ANCA-associated vasculitis (AAV), ie granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA), in Southern France in 2018, and evaluate differences among Europeans and non-Europeans. METHODS: This population-based, cross-sectional study used four sources (hospitals, community-based physicians, laboratories, National Health Insurance) to identify adults ≥ 15 years diagnosed with GPA, MPA or EGPA, living in Hérault and Gard in 2018. Cases were defined using the ACR/EULAR classification criteria, and if necessary, the European Medicines Agency algorithm. Prevalence estimates were standardised to the world population and capture-recapture analysis was used to assess the comprehensiveness of the estimation. The influence of geographical origin was evaluated. RESULTS: 202 patients were selected, with 86 cases of GPA (42.6%), 85 cases of MPA (42.1%), and 31 cases of EGPA (15.3%). The standardised prevalence estimates per million inhabitants for 2018 were: 103 (95%CI 84 - 125) for AAV, 48 (95%CI 35 - 64) for GPA, 39 (95%CI 28 - 53) for MPA and 16 (95%CI 9 - 26) for EGPA, 36 (95%CI 25 - 50) for anti-PR3 positive AAV, 46 (95%CI 34 - 61) for anti-MPO positive AAV, and 16 (95%CI 9 - 26) for ANCA-negative AAV. The global estimation of comprehensiveness by capture-recapture analysis was 80.5%. The number of AAV cases was higher for non-European residents (P=0.001), particularly for MPA (P<0.0001). CONCLUSION: We provide a new estimate of AAV prevalence in France and show a higher prevalence of MPA in non-European patients.

Flare of Antiphospholipid Syndrome in the Course of COVID-19.

We report the case of a 48-year-old man followed since 2013 for primary antiphospholipid syndrome (APLS) revealed by venous thromboembolism in the presence of antiphospholipid antibodies (APL-Abs, anticardiolipin and anti-ß-2-glycoprotein-1), who decompensated in the course of coronavirus disease (COVID-19). Despite efficient anticoagulation, he suffered bilateral adrenal glands hemorrhage and limb arterial ischemia. The tropism of severe acute respiratory syndrome coronavirus-2 for endothelium can lead to microangiopathy and increased risk for thrombosis. If APL-Abs positivity can be an epiphenomenon under inflammatory and prothrombotic conditions, COVID-19 was herein responsible for disseminated thrombosis and a threat of catastrophic APLS, despite efficient anticoagulation.

Exophthalmos, Diplopia, and Bilateral Eyelid Edema: Symptoms of Ocular Mastocytosis.

PURPOSE: Mastocytosis is characterized by clonal mast cell proliferation with accumulation within various organs and uncontrolled activation with excessive mast cell mediator release. Ocular manifestations have rarely been published. We describe a 63-year-old man with bilateral exophthalmos that led to the diagnosis of systemic mastocytosis. CASE REPORT: A patient presented with bilateral eyelid edema with exophthalmos associated with binocular diplopia. Ophthalmologic examination showed bilateral axial, symmetrical, and painless exophthalmos with eyelid edema, and limitation in elevation of the right eye. Visual acuity was normal. Orbital magnetic resonance imaging showed increased volume of both the superior and medial recti muscles and right inferior oblique muscle, and histopathological examination of orbital fat and muscle biopsies revealed an infiltration by mast cells. Serum tryptase was elevated. The patient also complained of a long history of pruritis and diffuse skin erythema that could be elicited with just mild pressure (Darier's sign). A bone marrow biopsy confirmed the infiltration of abnormal mast cells with a D816V mutation in the KIT gene. Treatment with cladribine was initiated and resulted in resolution of both ocular and systemic signs and symptoms that persisted without relapse 18 months after discontinuation. Ocular mastocytosis is a rare condition, which was previously reported to involve the conjunctiva, cornea, uvea, eyelid, orbit, and choroid. Cases of ocular mastocytosis can be classified into two main groups: mast cells tumors (mastocytomas) and ocular manifestations associated with systemic mastocytosis. Histological examination of ocular samples is rarely performed, and there are no standard criteria for the diagnosis of ocular mastocytosis. Our case emphasizes cladribine could represent an alternative treatment. CONCLUSIONS: Our case is the first published case of exophthalmos and eyelid edema associated with systemic mastocytosis confirmed by pathologic examination of periocular biopsies that was treated effectively with cladribine.

Pulmonary cryptococcosis in a patient with Crohn's disease treated with prednisone, azathioprine and adalimumab: exposure to chicken manure as a source of contamination.

BACKGROUND: Biotherapies targeting TNFα were proven to be effective in the most severe cases of Crohn's Disease, a chronic granulomatous inflammatory bowel disease that can involve any portion of the digestive tract. The tolerance of anti-TNFα therapy is usually good, although several infectious complications have been reported with these drugs. METHODS: We report a case of a Crohn's disease patient who developed pulmonary cryptococcosis following chicken manure exposition while he received adalimumab and azathioprine. CASE: A 54-year-old man, with history of severe Crohn's disease and ankylosing spondylitis, was admitted for diarrhea and abdominal pain under azathioprine treatment. In December 2010, he was treated with oral prednisone (1 mg/kg/day), but Crohn's disease relapsed when prednisone dose was lower than 30 mg/a day. The patient was then treated with adalimumab, but six weeks later he developed severe pulmonary cryptococcosis. The patient experienced a good outcome under antifungal therapy. We retrospectively found a high exposure to chicken manure in the last weeks. CONCLUSION: Cryptococcosis is an opportunistic infection that can occur under anti-TNFα therapy. The environmental exposure to Cryptococcus spp. (in particular in chicken manure) is a source of contamination. Avoiding exposition to bird manure should be a recommendation for patients who are living in rural areas.
