IntroductionAdverse events (AEs) of immune checkpoint inhibitors (ICIs) are frequent and mainly due to an overactivity of the immune system leading to excessive inflammatory responses (immune-related AE) that can affect any organ of the body. Beside the most frequent AEs, there are rare AEs whose diagnosis and treatment can be challenging. We report here a singular case of capillary leak syndrome (CLS) associated with chylothorax occurring in a patient who has been treated with adjuvant nivolumab (anti-PD1) for resected AJCC stage IIB primary melanoma.Case presentationA 43-year-old woman was diagnosed with a nodular stage IIB melanoma of her left thigh, according to the AJCC 8th edition (T3bN0M0). The woman was treated with adjuvant nivolumab. She stopped the treatment after 4 infusions due to thrombopenia. Three months later, she developed facial and leg edema and ascites due to capillary leak syndrome. The CLS was associated with chylothorax and elevated vascular endothelial growth factor. The patient was initially treated with several pleural puncturing and steroids. CLS and chylothorax progressively decreased with intravenous immunoglobulins and fat-free diet without recurrence of melanoma at one-year follow-up.ConclusionCLS is a rare and potentially life-threatening AE of ICIs such as anti-PD1. This AE may be associated with chylothorax probably related to lymphatic permeability induced by anti-PD1. more...

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Angiosarcoma (AS) is a rare aggressive sarcoma with differentiation toward blood or lymphatic endothelium. There are few epidemiological data available on AS. To address this limitation, we investigated the epidemiological and clinical features of angiosarcoma diagnosed in a French administrative area (the Doubs department) from 1979 to 2016. A retrospective cohort study was conducted using the Doubs cancer registry database. A total of 45 patients with invasive AS were diagnosed between 1979 and 2016 in the Doubs department. Among the 45 AS, 51% were either cutaneous AS (27%), including head and neck and extremities, or breast AS (24%) as compared to visceral AS (42%). Eleven patients had metastasis at diagnosis (26%). Age-standardized incidence rate was 0.15 per 100,000 persons-years (95%CI, 0.10–0.20) for the entire study period (1979–2016) and 0.26 (95%CI, 0.15–0.42) for the last decade (2007–2016). Crude survival at 1, 3, 5 years after diagnosis was 44%, 21%, and 12%, respectively. Our population-based study provides updated data on the incidence and overall survival of AS in a French population-based cancer registry. more...

Dermatology ,RL1-803 - Abstract
Background. Although infliximab (IFX) has been available since 2005, there are very little data on the long-term drug survival of infliximab in real-life. Objective. Our aim was to identify and describe psoriasis patients treated with IFX for longer than 6 years. Methods. Psoriasis patients treated with IFX for longer than 6 years were retrospectively included. Demographic and clinical data were collected in May 2018. Results. Between January 2005 and December 2012, 43 patients were maintained on IFX for 6 years or longer. IFX was introduced as a 4.5 line of systemic therapy. The mean duration of IFX treatment was 8.5 years (6–12). In May 2018, 30 patients (70%) were still maintained on IFX at 4–6 mg/kg every 8–10 weeks with an efficiency of about 100%. IFX was stopped in 13 patients (30%) mainly for loss of efficacy in 6 patients (46%). Three patients developed solid cancer including bladder cancer, lung cancer, and prostate cancer. Limitation. Retrospective study. Conclusion. We report the efficacy and safety of IFX maintained for up to 12 years in psoriasis patients. The long-term use of IFX was associated with a high BMI confirming the critical role of weight-based dosing for this drug. more...

Background: The long-term effectiveness of immune checkpoint inhibitor (ICI) rechallenge for progressive or recurrent advanced melanoma following previous disease control induced by ICI has not been thoroughly described in the literature. Patients and methods: In this retrospective multicenter national real-life study, we enrolled patients who had been rechallenged with an ICI after achieving disease control with a first course of ICI, which was subsequently interrupted. The primary objective was to evaluate tumor response, while the secondary objectives included assessing the safety profile, identifying factors associated with tumor response, and evaluating survival outcomes. Results: A total of 85 patients from 12 centers were included in the study. These patients had advanced (unresectable stage III or stage IV) melanoma that had been previously treated and controlled with a first course of ICI before undergoing rechallenge with ICI. The rechallenge treatments consisted of pembrolizumab (n = 44, 52%), nivolumab (n = 35, 41%), ipilimumab (n = 2, 2%), or ipilimumab plus nivolumab (n = 4, 5%). The best overall response rate was 54%. The best response was a complete response in 30 patients (35%), a partial response in 16 patients (19%), stable disease in 18 patients (21%) and progressive disease in 21 patients (25%). Twenty-eight adverse events (AEs) were reported in 23 patients (27%), including 18 grade 1–2 AEs in 14 patients (16%) and 10 grade 3–4 AEs in nine patients (11%). The median progression-free survival (PFS) was 21 months, and the median overall survival (OS) was not reached at the time of analysis. Patients who received another systemic treatment (chemotherapy, targeted therapy or clinical trial) between the two courses of ICI had a lower response to rechallenge (p = 0.035) and shorter PFS (p = 0.016). Conclusion: Rechallenging advanced melanoma patients with ICI after previous disease control induced by these inhibitors resulted in high response rates (54%) and disease control (75%). Therefore, ICI rechallenge should be considered as a relevant therapeutic option. more...

Resume Introduction L’elastolyse du derme papillaire – pseudoxanthome elastique-like (PXE-PDE) est une entite rare, ressemblant cliniquement au pseudoxanthome elastique (PXE). Nous en rapportons un cas typique. Observation Une femme de 77 ans consultait pour une eruption papuleuse acquise qui evoluait depuis environ quatre ans. Son seul antecedent pathologique etait un cancer du sein en remission. L’eruption avait debute sur l’aisselle droite puis s’etait etendue sur l’hemithorax droit puis l’aisselle gauche, ainsi que sur le haut de la nuque et le pli inguinal droit. Il n’y avait pas de signe fonctionnel associe. Les papules etaient non folliculaires, molles, couleur chair, sans anetodermie. L’examen histologique en coloration hematoxyline-eosine et a l’orceine mettait en evidence une elastolyse du derme papillaire et moyen, sans elastorrhexie. Devant cet aspect clinique de PXE mais avec une elastolyse histologique, le diagnostic de PXE-PDE etait pose. Discussion Le PXE-PDE est une maladie rare, acquise, qui affecte exclusivement la femme, habituellement apres 60 ans. Bien que cliniquement proche du PXE, le PXE-PDE s’en differencie par son âge d’apparition tardif, l’absence d’atteinte systemique et son aspect histologique. L’examen dermoscopique peut egalement contribuer au diagnostic differentiel. L’anatomopathologie fait le diagnostic de certitude en montrant des fibres elastiques normales mais rarefiees, voire totalement absentes, dans le derme papillaire et moyen. La physiopathologie reste imprecise ; elle impliquerait le vieillissement cutane, des anomalies de l’elastogenese et l’exposition aux UV. Aucun traitement n’a montre d’efficacite. Conclusion Le PXE-PDE est une pathologie rare, d’aspect anatomoclinique stereotype. La connaissance de cette entite permet d’eviter les explorations complementaires inutiles et de rassurer rapidement le patient. more...

Summary Introduction Incontinentia pigmenti (IP) is an X-linked genodermatosis caused by mutation of the NEMO/IKBKG gene. While lethal in male foetuses, heterozygous females survive because of X-inactivation mosaicism. Herein we discuss 9 male patients with IP. Materials and methods This is an observational, descriptive, retrospective, multicentre, French study carried out with the help of the SFDP research group. Statistical analysis was performed both on our own patients and on those reported in the literature. Results Nine boys with no family history of IP but with typical neonatal skin reactions were included. Genetic analysis of blood (n = 8) and skin biopsy (n = 3) confirmed the diagnosis of IP by identification of common deletion of the IKBKG/NEMO gene (exons 4 to 10) in the state of somatic mosaic in 6 and 2 cases respectively. Where analysed, the karyotype was normal (n = 6). Over a median follow-up period of 48 months (3 months to 10 years), 3 patients had neurological abnormalities, 2 had severe ophthalmologic abnormalities, and 1 had dental abnormalities. Extensive skin involvement is a systemic risk factor, unlike cutaneous scarring. Conclusion IP in boys is often due to a mosaic mutation that should be sought in blood and skin. Long-term neurological and ophthalmological monitoring is essential, especially in cases of extensive skin involvement. more...

Introduction Le dupilumab est la premiere biotherapie disponible pour la dermatite atopique (DA). Il repose sur l’inhibition de l’IL-4 et de l’IL-13. Cette therapie peut entrainer des conjonctivites, dont l’incidence est evaluee a 5–28 % selon les etudes cliniques. Les mecanismes impliques dans la conjonctivite associee au dupilumab (CAD) ne sont pas elucides. Notre objectif etait d’etudier la faisabilite et de comparer les profils cytokiniques des larmes collectees de facon non invasive avant puis sous traitement par dupilumab, chez les patients avec et sans conjonctivite induite. Materiel et methodes Nous avons mene une etude prospective monocentrique de patients recevant du dupilumab pour une DA. Des echantillons lacrymaux etaient collectes par capillarite a l’initiation du traitement, puis a 4 mois et 8 mois apres l’instauration. Les patients ayant developpe une conjonctivite etaient suivis ensuite tous les deux mois. Une recherche de demodex sur les cils etait aussi effectuee a l’instauration. Les dosages d’IL-2, 4, 6, 10, 17A, d’IFNg et de TNFa etaient realises en cytometrie de flux. Une numeration et formule des leucocytes lacrymaux etait aussi effectuee. Resultats Vingt et un patients traites par dupilumab etaient inclus et 10 controles sains etaient aussi preleves pour comparaison. Cinq patients (24 %) ont developpe une conjonctivite induite, apres une moyenne de 2,3 mois. A l’instauration du dupilumab, le temps de rupture du film lacrymal au diagnostic etait plus court (6 secondes versus 4,5 s, NS) et le taux de lymphocytes lacrymaux etaient plus eleve chez les patients qui developpaient ensuite une conjonctivite. Les taux de cytokines lacrymales IL2, IL17A, IL10, IFNg semblaient plus eleves chez les patients qui ont ensuite developpe une CAD, mais non significatifs (p > 0,1), par rapport aux autres patients et temoins. L’IFNg, le TNF et l’IL-10 diminuaient sous traitement avec dupilumab (p Discussion Notre etude demontre la possibilite d’analyser de facon non invasive les cytokines dans les larmes de patients. Nos resultats preliminaires n’ont pas permis d’identifier de marqueur lacrymal significatif de CAD, probablement a cause d’un manque de puissance. Un taux eleve de lymphocytes et de polynucleaires eosinophiles au niveau lacrymal pourrait etre associe au developpement ulterieur d’une CAD. more...

Background Dissecting cellulitis of the scalp (DCS), also known as Hoffmann disease or perifolliculitis capitis abscedens et suffodiens, is a rare disease characterized by chronic inflammation of the scalp. Treatment is difficult and often disappointing. Objectives To report our experience of TNF inhibitors in a series of patients with DCS. Materials & methods We conducted a monocentric retrospective study of nine patients with DCS treated with TNF blocker after failure of other conventional treatments. Results After a mean duration of treatment by TNF inhibitors of 17 ± 16 months, four patients (44% versus 0%) had a Physician's Global Assessment score of 0 or 1. We observed a 67% reduction in the number of inflammatory nodules, an 88% reduction in purulent drainage and a 45% improvement in Dermatology Life Quality Index. The mean treatment satisfaction index was 6.6 ± 1.6 out of 10. Conclusion Our study suggests that TNF inhibitors are effective against disease activity and may improve quality of life in the management of DCS refractory to conventional treatments. more...

CD4 T cells play a key role in anticancer immunity. In this study, we investigate the clinical relevance of circulating CD4 T helper type 1 (Th1) response against telomerase (anti-TERT Th1 response) in patients with melanoma. The spontaneous anti-TERT Th1 response was detected in 54.5% (85/156) of patients with melanoma before treatment. The prevalence of this systemic response was inversely related to Breslow thickness >1 mm and American Joint Committee on Cancer stage ≥II (P = 0.001 and 0.032, respectively). In contrast to patients treated with targeted therapies, the anti-TERT Th1 immunity was associated with an objective response after immune checkpoint inhibitors treatment. Hence, 86% (18/21) of responder patients exhibited pre-existing anti-TERT Th1 versus 35% (6/19) in nonresponders (P = 0.001). This response was also associated with increased progression-free survival and overall survival in patients with melanoma treated with immune checkpoint inhibitors (P = 0.0008 and 0.012, respectively). Collectively, the presence of circulating anti-TERT Th1 response is inversely related to melanoma evolution and appears to be a predictive factor of response to immunotherapy. Our results highlight the interest in telomerase-specific CD4 Th1 response as a promising blood-based biomarker of immune checkpoint inhibitors therapy in melanoma. more...

Follow-up of juvenile dermatomyositis (JDM) patients has demonstrated the impact of the disease on several organs in the long term.As there is little information on the long-term outcome of JDM, we aimed to assess long-term outcomes in a series of JDM patients.After selection of JDM patients, a consultation with a dermatologist and a rheumatologist was held for each patient. Cutaneous, muscle, and disease damage was assessed using different validated scores including the abbreviated Cutaneous Assessment Tool (aCAT), 8-muscle Manual Muscle Testing (MMT8), Childhood Myositis Assessment Scale (CMAS), Myositis Damage Index (MDI), Childhood Health Assessment Questionnaire (CHAQ), and Health Assessment Questionnaire (HAQ). Long-term disease outcomes were recorded including growth and pubertal development, educational and vocational achievement, and development of comorbidities.Seven patients were included in the study. After a mean follow-up of 14.9±8.8 years, the mean aCAT score was 0.57±1.4 and only one patient had a positive aCAT activity score. The mean aCAT damage score was 1.4±1.3 and five (71%) patients had a score of ≥1. Five (71.4%) patients had normal muscle strength with an MMT8 score of72, and none had severe muscle weakness (MMT8 ≤32, and CMAS35). The mean total extent of damage according to the MDI was ≥1 in five (71%) patients and mainly involved the skin. Two (29%) patients had mild disability according to the CHAQ/HAQ disability index. In terms of quality of life, no patient had a score of40 (1 SD below the mean for healthy controls).Based on validated cutaneous and musculoskeletal scores, our study demonstrated the good functional outcomes of JDM at long-term follow-up. more...

Angiosarcoma (AS) is a rare aggressive sarcoma with differentiation toward blood or lymphatic endothelium. There are few epidemiological data available on AS. To address this limitation, we investigated the epidemiological and clinical features of angiosarcoma diagnosed in a French administrative area (the Doubs department) from 1979 to 2016. A retrospective cohort study was conducted using the Doubs cancer registry database. A total of 45 patients with invasive AS were diagnosed between 1979 and 2016 in the Doubs department. Among the 45 AS, 51% were either cutaneous AS (27%), including head and neck and extremities, or breast AS (24%) as compared to visceral AS (42%). Eleven patients had metastasis at diagnosis (26%). Age-standardized incidence rate was 0.15 per 100,000 persons-years (95%CI, 0.10–0.20) for the entire study period (1979–2016) and 0.26 (95%CI, 0.15–0.42) for the last decade (2007–2016). Crude survival at 1, 3, 5 years after diagnosis was 44%, 21%, and 12%, respectively. Our population-based study provides updated data on the incidence and overall survival of AS in a French population-based cancer registry. more...

Background Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare and potentially fatal adverse reaction. It can be difficult to diagnose, even more so among children, because symptoms may mimic other commonly encountered pediatric conditions. Objective To describe clinical and laboratory features of DRESS syndrome in the pediatric population (age ≤18 years) and establish causative agents and treatment modalities. Methods This was a multicenter retrospective study of probable and definite DRESS cases (Registry of Sever Cutaneous Adverse Reaction score ≥ 4) in children hospitalized in 15 French university hospitals between 2000 and 2020. Results We included 49 cases. All children had fever and rash, 69.4% had lymphadenopathy, and 65.3% had facial edema. The most common organ affected was the liver (83.7%). Treatment consisted of topical corticosteroid in only 30.6% and systemic corticosteroid in 55.1%; 12.2% received intravenous immunoglobulin. Among probable and likely culprit drugs, 65% were antibiotics and 27.5% were antiepileptics, median time to DRESS symptom onset after initiation of 15 days (13 days with antibiotics and 21 days with antiepileptics). Twenty-seven children had allergy assessment for causative agents, 65.4% of whom had positive tests. Conclusions Culprit drugs are frequently antibiotics and antiepileptic drugs, and onset is often less than 2 weeks after treatment starts, especially with antibiotics. Treatment with topical corticosteroids appears to be sufficient in the least severe cases. Treatment by systemic corticosteroid therapy remains the reference treatment in case of severe organ damage. more...

Little is known about whether immunosuppressed patients mount the immunological response necessary to ensure tubal occlusion. Theoretical concern for non-occlusion has limited the use of hysteroscopic sterilization in patients on immunosuppressive therapies. The effects of tumor necrosis factor-alpha (TNF-α) blockers and interleukin (IL)-17 inhibitors on contraception and pregnancy for patients with psoriasis are poorly documented. We report a case of pregnancy that ended in miscarriage in a patient treated first with TNF-α and then with IL-17 inhibitors for severe psoriasis after tubal sterilization with micro-inserts. Our observation suggests that the efficacy of tubal sterilization by micro-inserts may be impaired by these two biologics and that the risk of miscarriage may be increased in women with psoriasis treated with secukinumab. more...

Resume Introduction Le granulome annulaire fait partie des reactions granulomateuses qui peuvent etre induites par des medicaments. L’immunotherapie par anti-PD1 est utilisee dans le traitement des melanomes et d’autres cancers solides. Nous rapportons deux cas de granulome annulaire survenus chez des patientes traitees par un anti-PD1, le pembrolizumab. Observations Deux femmes traitees par pembrolizumab toutes les 3 semaines pour un melanome metastatique ont developpe un granulome annulaire sous traitement. L’immunotherapie a ete maintenue dans les deux cas. Les lesions ont continue d’evoluer par poussees et remissions chez la premiere patiente, alors qu’une disparition complete etait constatee apres un mois de corticotherapie locale chez la seconde. Discussion La survenue de reactions granulomateuses sous immunotherapie est connue et decrite dans la litterature, mais aucun cas de granulome annulaire induit par anti-PD1 n’avait ete rapporte jusqu’ici. L’hypothese pathogenique est qu’une dysregulation de l’immunite cellulaire secondaire au traitement entrainerait un processus reactionnel granulomateux dans les organes cibles. Le granulome annulaire fait donc partie des effets secondaires cutanes possibles sous anti-PD1. more...

Introduction Le granulome pyogenique ou botriomycome est une tumeur benigne acquise frequente. Nous rapportons 2 cas de granulomes pyogeniques eruptifs survenus spontanement sur des angiomes plans pre existants chez deux enfants. Materiel et methodes Cas N°1: Un enfant de 4 ans, de phototype V, etait vu en consultation pour l’apparition spontanee de multiples lesions tumorales saignotantes sur son angiome plan segmentaire du thorax. Certaines lesions de grande taille etant hemorragiques, une chirurgie etait realisee permettant de confirmer le diagnostic evoque cliniquement de granulomes pyogeniques. Dans les annees qui suivirent, l’enfant necessitait regulierement l’exerese de nouveaux granulomes pyogeniques. Un traitement par timolol maleate topique puis propranolol par voie orale ne permettaient pas d’empecher l’apparition de nouvelles lesions. Un traitement par laser vasculaire fut propose a l’âge de 16 ans. Cas No2 : un adolescent de 15 ans etait vu en consultation pour de multiples lesions survenues spontanement sur son angiome plan de la face (territoire V1–V2 gauche). L’analyse histologique d’une des lesions confirmait le diagnostic de granulome pyogenique. Un traitement par laser vasculaire n’empechait pas la survenue d’autres lesions, dont certaines necessiterent une exerese chirurgicale. Discussion Le granulome pyogenique est une tumeur benigne de cause inconnue mais survenant le plus souvent dans les suites d’un traumatisme, parfois mineur. Sa physiopathogenie reste inconnue mais l’hypothese d’un mecanisme declenchant la production de facteurs angiogeniques stimulant la proliferation endotheliale et la formation de fistules arterioveineuses est privilegiee. La survenue de granulomes pyogeniques sur des malformations vasculaires preexistantes a ete ponctuellement rapportee, en particulier sur des angiomes plans ou des malformations arterioveineuses mais il s’agit le plus souvent de lesion unique et apparue dans des circonstances favorisantes telles que la grossesse ou les traumatismes, en particulier apres traitement de la malformation vasculaire par cryotherapie ou laser vasculaire. Deux cas de granulomes pyogeniques multiples en plaque survenus sur des angiomes plans chez des enfants de moins de 1 an ont ete rapportes. Concernant la prise en charge de ces lesions, des options therapeutiques classiques telles que l’exerese chirurgicale, la cryotherapie et le laser vasculaire peuvent etre proposees. Plus recemment les beta-bloquants topiques ou per os ont ete rapportes comme efficaces, ce qui n’a pas ete le cas pour notre 1er patient. La survenue spontanee de granulomes pyogeniques eruptifs est donc une complication tardive possible des angiomes plans. more...

Introduction Le dupilumab est la premiere biotherapie disponible pour le traitement de la dermatite atopique (DA) moderee a severe de l’enfant âge de 6 a 11 ans, necessitant un traitement systemique. Sa prescription en France a ete possible par l’intermediaire d’une ATU depuis aout 2020. L’objectif de cette etude etait d’evaluer son efficacite et sa tolerance en vie courante a partir des donnees observationnelles des centres prescripteurs francais. Materiel et methodes Il s’agit d’une cohorte retrospective multicentrique. Les enfants ( Resultats 80 enfants (âge moyen : 9,6 ± 2,0 ans ; fille, n = 46, 57,5%) ont ete inclus. A M3, il existait une diminution significative du SCORAD moyen : 21,8 ± 13,8 a M3 vs 54,0 ± 17,8 a J0 ; p 500/mm3) n’etait significativement pas plus elevee a M3 (n = 40) qu’avant le traitement (n = 39), cependant on notait une majoration de l’hypereosinophilie a plus de 2500/mm3 chez 3 patients a 3 mois. 31 patients ont presente des poussees de DA sous traitement dont 3 avec une localisation « tete et cou ». 14 (17%) ont signale des douleurs au site d’injection ; et 5 (6%) ont arrete le traitement, dont 2 du fait des douleurs et contraintes liees a l’injection. Discussion Cette etude rapporte les premieres donnees en vie courante d’enfants de moins de 12 ans traites par dupilumab. Les limites sont le caractere retrospectif et le nombre de donnees manquantes. Les resultats suggerent une efficacite a M3, superposable aux donnees des essais chez l’enfant. Les effets indesirables telles que les conjonctivites et l’hypereosinophilie semblent etre identiques a ceux de l’adulte, par contre les poussees « tete et cou » semblent etre moins frequentes chez l’enfant. Les douleurs et contraintes de l’injection peuvent etre un motif d’arret de traitement plus frequent a prendre en compte. Ces premieres donnees en vie courante confirment l’efficacite du dupilumab chez l’enfant atteint de DA moderee a severe avec une bonne tolerance. Cependant, le mode d’administration sous forme injectable peut etre un frein a cet âge. more...

Introduction Le lupus erythemateux systemique (LES) a debut pediatrique est une maladie rare. Nous rapportons un cas de LES du nourrisson. Materiel et methodes Un nourrisson de sexe feminin de 14 mois presentait depuis l’âge de 9 mois des lesions erythemato-squameuses infiltrees asymptomatiques du visage, persistantes malgre l’application de dermocorticoides et de tacrolimus topique, associees a des ulcerations buccales. Le reste de l’examen clinique notait une stagnation ponderale depuis l’âge de 9 mois et une cassure de taille a 12 mois. Biologiquement on retrouvait un complement total effondre, des fractions C3, C4 normales, des anticorps anti-nucleaires a 1/640 et la positivite des anticorps anti-cardiolipides IgG a 101 unites et anti-beta-2-glycoproteine 1 IgG a 133 unites. Le reste du bilan biologique etait normal. La signature interferon etait positive tandis que le bilan immunologique maternel etait negatif. Le diagnostic de lupus erythemateux systemique a debut precoce etait donc retenu. Compte tenu de l’âge de debut du LES et de l’abaissement du CH50, un dosage de C1q etait realise et effondre : 12 mg/L (118-244). Une analyse genetique etait effectuee montrant un variant faux-sens homozygote dans le gene C1QA considere comme pathogene et herite de chacun des 2 parents avec un risque de recidive de 25 % pour une prochaine grossesse. D’un point de vu therapeutique une association hydroxychloroquine-corticotherapie orale etait debutee, associee ensuite a du methotrexate. Devant la persistance des lesions cutanees, de la stagnation ponderale et l’apparition d’arthralgies inflammatoires, le methotrexate etait remplace par du mycophenolate mofetil (dosage selon AUC). Discussion Le lupus systemique infantile est une entite rare. Il est caracterise par sa plus grande severite. Il n’existe pas de consensus sur le suivi et sur le traitement pour ces formes a debut pediatrique. Devant un LES d’apparition precoce il est necessaire de penser au lupus monogenique a transmission autosomique recessive ou dominante, en particulier en cas de deficit du complement (principalement C1q et C4) ou de signature interferon tres positives (interferonopathies). L’identification de nouvelles voies moleculaires impliquees dans ces LES pourrait conduire a la decouverte de nouvelles cibles therapeutiques. more...

Introduction Les progres therapeutiques (immunotherapie [IT] et therapies ciblees [TC]) ont transforme la prise en charge du melanome metastatique (MM) avec une efficacite autorisant eventuellement l’interruption du traitement (Tt) et une remission sur plusieurs annees. Materiel et methodes Nous avons realise un sondage (e-mails) sous l’egide du Groupe de Cancerologie Cutanee afin de decrire les pratiques cliniques d’arret des anti-PD1 et de suivi apres Tt systemique d’un MM. Resultats Nous avons recueilli l’avis de 30 praticiens (29 dermatologues et 1 oncologue) travaillant dans 26 centres (20 centres hospitaliers universitaires, 7 hopitaux generaux, 4 centres de lutte contre le cancer et 1 clinique privee) en France. En cas de controle d’un MM, l’interruption de l’IT anti-PD1 etait proposee apres reponse complete (RC) > 12 mois (50 %), > 6 mois (43 %), apres reponse partielle (RP) > 24 mois (23 %), > 12 mois (13 %) ou apres stabilite de la maladie > 24 mois (27 %). Neanmoins, une partie des praticiens n’interrompait pas l’IT anti-PD1 en cas de stabilite (37 %) ou de RP (23 %). Concernant la surveillance (Surv) apres Tt d’un MM, les praticiens proposaient une Surv clinique trimestrielle pendant 3 an s puis semestrielle pendant 2 ans puis annuelle a vie (80 %, 97 % et 55 % des medecins apres Tt adjuvant (Adj), IT anti-PD1 et lors d’une reponse (R) prolongee aux TC (> 2–3 ans) respectivement. Concernant l’imagerie, une Surv par echographie (57 %, 27 % et 20 %) et scanner/PET-scanner/IRM cerebrale (70 %, 83 % et 77 %) tous les 3–6 mois pendant 3 ans etait proposee apres Tt Adj, apres IT anti-PD1 et lors d’une R prolongee aux TC, respectivement. Les praticiens proposaient de poursuivre une Surv par imagerie au-dela de 3 ans de Surv apres IT anti-PD1 (27 %) et R prolongee aux TC (60 %). La Surv biologique (LDH) etait proposee par 70 % des medecins apres IT anti-PD1, par 83 % des medecins en cas de R prolongee aux TC et plus rarement (36 %) apres Tt Adj. Lors d’une R prolongee aux TC, les praticiens proposaient une Surv biologique a vie. Le suivi de l’ADN tumoral circulant etait propose par 20 % des medecins lors d’une R aux TC et par 10 % dans les autres cas. Discussion Les pratiques semblent globalement homogenes. Une surveillance clinique trimestrielle pendant 3 ans puis semestrielle pendant 2 ans puis annuelle a vie avec une imagerie tous les 3–6 mois pendant 3 ans sont rapportees par la majorite des medecins repondeurs. L’imagerie et la surveillance biologique sont realisees de facon plus prolongee lors d’une reponse prolongee aux TC. L’arret des anti-PD1 est propose un peu plus tardivement que dans les recommandations de l’ESMO 2020 (6 mois de RC). La place de l’ADN tumoral circulant doit etre evaluee. Dans le futur, des etudes evaluant le devenir a long terme des patients atteints de melanome avance traites par IT ou TC permettront d’ameliorer les modalites de suivi de nos patients. more...

Monoclonal antibodies targeted against the immune checkpoint molecules CTLA-4 and PD-1 have recently obtained approval for the treatment of metastatic melanoma and advanced/refractory non small-cell lung cancers and metastatic renal cancer. Besides their efficacy profile, these immune targeted agents also generate immune-related adverse events that may be life threatening if not anticipated and managed appropriately. This new family of dysimmune toxicities remains largely unknown to the broad oncology community. We propose here some practical guidelines for the oncologist to help in the clinical care of patients under immune checkpoint molecules. more...

Ischemic digital ulcers (DU) represent a major complication of systemic sclerosis (SSc). We investigated the impact of controlling the ulcerative disease on disability, pain, and quality of life in SSc patients receiving bosentan.ECLIPSE (Study AC-052-517) is a 2-year prospective, multicenter, and observational study. Patients with SSc who experienced at least 1 DU in the previous year and received bosentan were included between October 2009 and March 2011. Disability scores [Cochin Hand Function Scale (CHFS) and Health Assessment Questionnaire Disability Index (HAQ-DI)], pain scores (visual analog scale), and quality-of-life scores (SF-36) were collected at inclusion and 1 year later (primary endpoint). A controlled ulcerative disease was defined by the absence of ongoing/new DU episode between inclusion and 1-year follow-up.Data were available at 1 year for 120 patients out of 190 included. During follow-up, 46 (38.3%) patients experienced a new DU episode. The number of DU per patient decreased from 1.4 ± 1.8 at inclusion to 0.6 ± 1.6 (p0.0001) at 1 year. Disability scores decreased from 1.0 ± 0.7 to 0.9 ± 0.7 (p = 0.04) for the HAQ-DI and from 29 ± 20 to 25 ± 20 (p = 0.005) for the CHFS; the pain score decreased from 4.3 ± 3.1 to 2.9 ± 2.8 (p0.0001). This improvement was attributed to patients with a controlled ulcerative disease (48.3%), who significantly improved HAQ-DI (p = 0.04), CHFS (p = 0.04), and pain score (p = 0.046).In patients with SSc, control of the ulcerative disease for 1 year was associated with significant attenuation of hand disability. more...

Dermatology - Abstract
Introduction Le developpement des immunotherapies a revolutionne la prise en charge des cancers, notamment celle du carcinome epidermoide cutane avance. Le cemiplimab, un anti-PD1, a demontre son efficacite dans un essai de phase II chez les patients atteints de carcinome epidermoide cutane (CEC) avance. L’objectif de notre travail etait de rapporter les donnees de vie reelle d’efficacite du cemiplimab dans le traitement du CEC avance. Materiel et methodes Nous avons inclus les patients traites par cemiplimab (3 mg/kg toutes les 2 semaines IV ou 350 mg toutes les 3 semaines) pour un carcinome epidermoide cutane (CEC) inoperable ou metastatique au CHU de Besancon. Nous avons evalue l’efficacite et la tolerance du traitement. La reponse au traitement etait evaluee selon les criteres radiologiques RECIST 1.1. Resultats Nous avons retrospectivement inclus 15 patients atteints de CEC avances ayant recu un traitement par cemiplimab entre aout 2018 et mai 2020. Les patients etaient des hommes (n = 15, 100 %), d’âge median de 80 ans (45–96 ans), prealablement traites par chirurgie (n = 9, 60 %), radiotherapie (n = 8, 53 %) ou chimiotherapie (n = 2, 13 %) pour un CEC stade III de l’AJCC (n = 4, 27 %) ou stade IV (n = 11, 73 %). Le taux de reponse globale etait de 73 % (n = 11), incluant 9 reponses partielles (60 %) et 2 reponses completes (13 %). Quatre patients n’ont pas repondu au traitement (27 %) dont un patient qui a presente une reponse dissociee. Trois patients sont decedes au cours du suivi dont 1 seul de son CEC avance. Un patient est decede de la COVID-19 et un patient est decede des complications d’un autre cancer. Vingt pour cent des patients ont presente des toxicites de grades 1–2 (n = 3) n’ayant pas empeche la poursuite du traitement. Aucune toxicite severe n’etait observee. Les medianes de survie sans recidive et de survie globale n’etaient pas atteintes apres un suivi median de 6 mois (de 1 a 20 mois). Discussion Nous rapportons un taux de reponse globale superieur a celui rapporte dans la litterature (73 % versus 47 % dans l’etude de phase II de Midgen et al. NEJM 2018). Cette difference pourrait etre due au faible effectif de notre cohorte, mais suggere une bonne efficacite du cemiplimab dans une population differente de celle des essais cliniques. Ainsi, nos resultats confirment l’efficacite et la tolerance du cemiplimab en vie reelle. D’autres etudes de plus grands effectifs sont necessaires pour confirmer ces resultats encourageants dans une pathologie au pronostic severe. more...

Dermatology - Abstract
Introduction Certaines causes genetiques doivent etre evoquees devant un eczema severe ne repondant pas aux traitements usuels. Nous rapportons le cas d’un enfant atteint d’eczema severe dont le bilan a mis en evidence une mutation gain de fonction (GOF) de JAK1, ameliore par un traitement par baricitinib. Observations Un petit garcon de 11 ans etait suivi depuis l’âge de 6 mois pour une dermatite atopique severe associee a des allergies alimentaires multiples et a un asthme. Il presentait une dermatite atopique erythrodermique associee a un retard staturo-ponderal. Il n’avait jamais eu de complication infectieuse severe. Les dermocorticoides, le methotrexate et la ciclosporine etaient inefficaces avec un Scorad moyen a 60. Il avait developpe une insuffisance surrenalienne iatrogene liee aux dermocorticoides. Il existait une hypereosinophilie a 1300/mm3 et un taux d’IgE totales a 39 000 UI/mL. Au vu du contexte, une dermatite atopique syndromique etait evoquee. L’etude par sequencage haut debit (NGS) a mis en evidence la mutation heterozygote faux-sens c.415G > A, (p.Glu139Lys) de JAK1. Les etudes fonctionnelles ont permis de demontrer un impact GOF de la proteine codee par JAK1. L’enfant presentait donc une dermatite atopique severe liee a une mutation GOF de JAK1. Compte tenu de la gravite du tableau clinique un traitement par inhibiteur JAK1/2 (baricitinib) etait debute. A 3 mois de traitement, la dermatite atopique etait controlee avec un Scorad a 16. La tolerance clinique et biologique du traitement etait excellente. Discussion Les proteines JAK (JAK1/2/3 et TYK2) sont des tyrosine-kinases intra-cytoplasmiques. Elles regulent l’expression de genes impliques dans l’activation, la proliferation et la differenciation cellulaires. Dans un modele murin, une mutation GOF de JAK1 conduit a une dermatose prurigineuse avec anomalie de la differenciation et hyperproliferation des keratinocytes et surexpression de proteases a serine en particulier de peptidases apparentees a la kallikreine, ces dernieres ayant un role dans l’inflammation cutanee et la fonction barriere de la peau. Une seule publication rapporte le cas d’une famille avec une mutation GOF germinale de JAK1. Ces patients presentaient le meme phenotype clinique : une dermatite atopique severe, un retard staturo-ponderal, des allergies multiples et une hypereosinophilie sanguine. Un traitement par ruxolitinib (inhibiteur JAK1/2) a permis d’ameliorer la dermatose et les parametres de croissance et a entraine une reduction de l’hypereosinophilie. Les mutations gain de fonction de JAK1 sont une cause rare de dermatite atopique severe hereditaire avec hypereosinophilie. Le sequencage de ce gene pourrait donc etre envisage chez ces patients. more...

Dermatology - Abstract
La reponse immunitaire lymphocytaire T CD4 Th1 joue un role important dans l’immunite anti tumorale et a ete etudiee dans de nombreux cancers. Nous avons evalue la reponse immunitaire T CD4 Th1 grâce a la reponse T CD4 Th1 anti-telomerase (anti-TERT) chez des patients atteints de melanome de tous stades AJCC. La reponse anti-TERT des lymphocytes de patients atteints de melanome etait evaluee par ELISpot IFN-γ et comparee aux donnees clinico-biologiques des patients. Au total, 171 patients atteints de melanome etaient inclus et 156 d’entre eux avaient une evaluation de la reponse anti-TERT disponible. Une reponse anti-TERT etait retrouvee chez 55 % des patients. La reponse anti-TERT etait moins frequemment retrouvee lorsque les patients avaient un melanome primitif avec un indice de Breslow > a 1 mm et lorsque le stade AJCC etait ≥ II par rapport aux patients ayant un indice de Breslow ≤ 1 mm et un stade AJCC I (p = 0,010 et 0,032 respectivement). Les patients ayant une reponse anti-TERT repondaient plus frequemment a l’immunotherapie que ceux n’ayant pas de reponse anti-TERT (n = 22) (p = 0,007). Parmi les 3 parametres immunologiques mesures dans le sang des patients (MDSC, FGL1 soluble, PD-L1), le taux de MDSC etait correle de facon inverse a la presence d’une reponse anti-TERT (p = 0,008). La reponse immunitaire T CD4 Th1 anti-TERT apparait comme un facteur de bonne reponse a l’immunotherapie. Le suivi de la reponse anti-TERT represente un outil potentiel de suivi de la reponse anti-tumorale chez les patients atteints de melanome traites par immunotherapie. more...

Introduction Le belimumab est indique dans le lupus erythemateux systemique (LES), actif notamment dans ses manifestation cutaneomuqueuses. Le but de cette etude etait d’evaluer l’efficacite du belimumab dans le lupus erythemateux cutane (LEC) refractaire aux therapeutiques conventionnelles. Materiel et methodes Cette etude retrospective realisee entre 2014 et 2018 incluait tous les patients presentant un LEC evolutif, en poussee et resistant aux therapeutiques habituelles, qui ont ete traites par belimumab. L’efficacite de ce traitement etait evaluee cliniquement par les scores RCLASI, CLASI et DLQI apres 6 a 12 mois de traitement. Le suivi global sous belimumab, incluant la tolerance et l’evolution des traitements associes, etait egalement analyse. Resultats Sept patients suivis pour un LEC ont ete inclus. Une amelioration significative des scores d’activite RCLASI et CLASI etait constatee chez 83 % des patients (5/6), avec 1 reponse complete et 4 reponses partielles, sans aggravation des sequelles cutanees. Le score de qualite de vie DLQI etait significativement ameliore chez 80 % des patients (4/5). La corticotherapie orale a pu etre arretee chez tous les patients concernes. La tolerance etait bonne, avec la survenue d’un seul effet indesirable severe (bacteriemie). Discussion Le belimumab (anticorps monoclonal recombinant anti-BAFF (B-cell activating factor)), en bloquant la liaison de la proteine BAFF sur les lymphocytes B, inhibe la differenciation et la survie anormale des lymphocytes B a l’origine de la perte de tolerance du soi dans le LES. L’efficacite du belimumab sur les manifestations cutaneo-muqueuses du LES a ete observee dans une analyse post-hoc des etudes pilotes du medicament et dans plusieurs etude en vie reelle. Le belimumab est ainsi indique en 3e intention dans le traitement des manifestations dermatologiques du LES, apres le methotrexate et le thalidomide (PNDS Lupus systemique, 2017). Chong et al. (2014), ont montre des taux sanguins de BAFF plus eleves chez les patients avec un LEC chronique (LECC) associe a un LES que chez les patients atteints de LECC isole. Neanmoins, cette equipe a egalement montre une augmentation significative des taux d’ARNm de BAFF et de ses recepteurs dans la peau de LECC compare a la peau normale ou psoriasique, sans difference significative en fonction de la presence ou non d’un LES. Wenzel et al. (2018) ont confirme ces travaux, en montrant une augmentation de l’expression de BAFF et de ses recepteurs dans la peau de chaque sous type de LEC compare a la peau normale. Ces resultats suggerent l’interet du belimumab dans l’atteinte cutanee lupique, independamment de la presence d’une atteinte systemique lupique associee. Conclusion Notre travail demontre donc l’interet du belimumab sur l’activite de la maladie, sur la qualite de vie et sur la cortico-dependance dans une cohorte de 7 patients atteints de LEC severe, refractaire aux traitements habituels. more...
