French recommendations for the management of non-infectious chronic uveitis.

This French National Diagnostic and Care Protocol (NDPC) includes both pediatric and adult patients with non-infectious chronic uveitis (NICU) or non-infectious recurrent uveitis (NIRU). NICU is defined as uveitis that persists for at least 3 months or with frequent relapses occurring less than 3 months after cessation of treatment. NIRU is repeated episodes of uveitis separated by periods of inactivity of at least 3 months in the absence of treatment. Some of these NICU and NIRU are isolated. Others are associated with diseases that may affect various organs, such as uveitis associated with certain types of juvenile idiopathic arthritis, adult spondyloarthropathies or systemic diseases in children and adults such as Behçet's disease, granulomatoses or multiple sclerosis. The differential diagnoses of pseudo-uveitis, sometimes related to neoplasia, and uveitis of infectious origin are discussed, as well as the different forms of uveitis according to their main anatomical location (anterior, intermediate, posterior or panuveitis). We also describe the symptoms, known physiopathological mechanisms, useful complementary ophthalmological and extra-ophthalmological examinations, therapeutic management, monitoring and useful information on the risks associated with the disease or treatment. Finally, this protocol presents more general information on the care pathway, the professionals involved, patient associations, adaptations in the school or professional environment and other measures that may be implemented to manage the repercussions of these chronic diseases. Because local or systemic corticosteroids are usually necessary, these treatments and the risks associated with their prolonged use are the subject of particular attention and specific recommendations. The same information is provided for systemic immunomodulatory treatments, immunosuppressive drugs, sometimes including anti-TNFα antibodies or other biotherapies. Certain particularly important recommendations for patient management are highlighted in summary tables.

[Familial chilblain lupus: Four cases spanning three generations]. / Lupus-engelures familial : quatre cas sur trois générations.

BACKGROUND: Familial chilblain lupus is a hereditary form of cutaneous lupus erythematosus seen in young children. It shows autosomal dominant inheritance due to mutations in the TREX-1 gene, or, more rarely, SAMHD1 or TMEM173 (STING). It belongs to the type I interferonopathies, i.e. inflammatory diseases associated with excessive interferon production and characterized by a positive "interferon signature". This is a rare entity with fewer than 10 families described to date. We report a new family followed over several years. PATIENTS AND METHODS: The patients were four subjects from the same family and spanning three generations (a brother and sister aged 17 and 15 years, their 39-year-old mother, and their 60-year-old grandfather). The initial cutaneous lesions on the extremities were described as papular, erythematous, purplish, infiltrated, hyperkeratotic, pruritic and/or painful. They occurred in childhood, improved during summer and stabilized over time. Immunological abnormalities such as positive antinuclear antibodies were noted. The interferon signature was positive in all patients. Molecular analysis of TREX-1, SAMHD1 and STING genes in both children showed no evidence of mutation. DISCUSSION: The cutaneous involvement was classic except for absence of the scarring and mutilating progression, photosensitivity and vasculopathy reported in other families. There was no intrafamily variability other than unconstant immunological abnormalities. At the molecular level, no mutations in the known genes were identified. A complementary molecular analysis is in progress. CONCLUSION: We report a new case of familial LEF, thus adding to knowledge about this very rare form of lupus erythematosus.

[Pansclerotic morphea with a rapidly fatal outcome in an 11-year-old girl]. / Morphée pansclérotique d'évolution rapidement létale chez une jeune fille de 11ans.

BACKGROUND: Pansclerotic morphea is a poorly described but extremely debilitating variant of localized scleroderma. We report a case with a rapidly fatal outcome in an 11-year-old girl. PATIENTS AND METHODS: An 11-year-old girl with a 2-year history of morphea presented at our institution in April 2012. The sclerosis had started on her trunk and progressed rapidly to involve her entire skin. Initial treatment with corticosteroids was ineffective and she presented extremely painful ulcerations of the lower limbs. The outcome was rapidly fatal, in early 2014, due to cachexia and sepsis after two amputations and several failed treatments including methotrexate. DISCUSSION: Pansclerotic morphea is characterized by rapidly progressing sclerosis involving the entire skin, trophic cutaneous ulcers, painful contraction and limited joint mobility. The prognosis is poor since the disease has an incapacitating and potentially fatal outcome. No reliably effective treatment has yet been established. CONCLUSION: Our case highlights the clinical characteristics of this uncommon form of localized scleroderma, the extremely severe prognosis, and the therapeutic challenge involved.

Complex regional pain syndrome type I in children. Clinical description and quality of life.

INTRODUCTION: Complex regional pain syndrome type 1 (CRPS I) in children differs from its adult counterpart and relevant literature is scarce. Our aim was to investigate potential risk factors and to assess midterm outcome and quality of life. MATERIAL AND METHODS: Medical records of patients diagnosed with CRPS I between 2004 and 2012 were analyzed. Patients and parents were called for a phone interview including the PEDS Quality of Life 4-0 questionnaire. Results were compared to a control group matched for age, gender and socio-economic status. RESULTS: Seventy-three patients were included (64 girls, 9 boys). Mean age at diagnosis was 11.5 years and mean time to diagnosis was 14.2 months. The lower limb was affected in 89% of cases. Allodynia, coldness and cyanosis were noted in 95%, 81% and of 74% of cases, respectively. Forty-nine percent of patients reported a physical injury. Multivariate analysis showed a strong association with being anxious (OR = 44.9, 95% CI [7.4-273]), presence of an atopic background (OR = 25.0, 95% CI: [4.6-135]), being good to excellent school performers (OR = 8.4 95% CI [1.3-52.1]), and having trouble falling asleep (OR = 5.3, 95% CI [1.6-17.0]). At a mean 37 months' follow-up (12-102), PEDS QL 4-0 score was significantly lower in CRPS patients compared to controls. Fifty-seven percent of patients acknowledged healing and 55% had presented a relapse. CONCLUSION: Childhood onset CRPS I affects predominantly preadolescent girls at the ankle. The present study highlights the relatively poor outcome, especially its physical and emotional aspects and the large role of psychology. LEVEL OF EVIDENCE: IV.
