RESUMEN

BACKGROUND: Cutaneous lupus erythematosus (CLE) may present as an isolated entity or be classified as Systemic lupus erythematosus (SLE) by the presence of laboratory abnormalities, including cytopenia, low complement levels, and/or autoantibodies (CLE with laboratory SLE). OBJECTIVE: To compare isolated CLE and CLE with laboratory SLE and to validate an existing 3-item score with age < 25 years (1 point), phototypes V to VI (1 point), antinuclear antibodies ≥ 1:320 (5 points) to predict the risk of progression from CLE to severe SLE (sSLE). METHODS: Monocentric cohort study including consecutive patients with CLE. CLE with laboratory SLE was defined by 2019 American College of Rheumatology/European League Against Rheumatism classification criteria for SLE score of ≥10 points at baseline with CLE as the sole clinical feature. RESULTS: Of the 149 patients with CLE, 20 had CLE with laboratory SLE. The median follow-up duration was 11.3 years (IQR: 5.1-20.5). Ten patients (7%) had sSLE developed. In survival analysis, the risk of progression to sSLE was higher among CLE with laboratory SLE (hazard ratio = 6.69; 95% CI: 1.93-23.14, P < .001) compared to isolated CLE. In both groups, none of the patients with a risk score ≤ 2 had sSLE developed. LIMITATIONS: Monocentric study with a limited number of patients. CONCLUSIONS: CLE with laboratory patients with SLE have a higher risk of progression to sSLE than isolated CLE.

RESUMEN

OBJECTIVES: To assess the prevalence, characteristics and knowledge about photosensitivity and the use of photoprotective measures in an international cohort of cutaneous and systemic lupus erythematosus patients. METHODS: We conducted an international, cross-sectional study based on a 46-question web-based survey including patients with medically confirmed LE conducted between November 2021 and April 2022. RESULTS: 600 patients with lupus erythematosus (94% female, median age: 41 years [IQR: 33-51]) from 50 countries were included. A history of photosensitivity was reported by 389/600 (64.8%) patients. Photosensitivity was associated with the presence of other cutaneous involvement (OR = 3.8; 95%CI 2.5-5.7; p < 0.001) and differed according to the area of habits and level of education (p < 0.001, for all). Photosensitivity was characterized by a wide range of clinical manifestations (both cutaneous and systemic symptoms in 56.1% and systemic symptoms only in 29.8% of patients). Fatigue was the most frequently reported systemic manifestation (82.3%). Overall, 559/600 (93%) patients were aware of the detrimental role of UV exposure in lupus erythematosus, but 160/480 (33.3%) were unaware of the importance of photoprotective measures, including 90/310 (29%) among those with photosensitivity. CONCLUSION: A high rate of self-reported photosensitivity characterize lupus erythematosus patients. Photosensitivity frequently includes subjective features, which makes it difficult to evaluate in clinical practice. As fatigue is frequent in LE, further study is needed to clarify its causal link with UV exposure. About one-third of lupus erythematosus patients are unaware of the importance of photoprotective measures. This should be improved through more frequent and targeted awareness interventions.

RESUMEN

OBJECTIVES: To describe the clinical and pathological features of biopsy-proven cutaneous vasculitis (CV) associated with SLE, focusing on diagnosis classification and impact on overall SLE activity. METHODS: Retrospective multicentric cohort study including SLE patients with biopsy-proven CV identified by (i) data from pathology departments of three university hospitals and (ii) a national call for cases. SLE was defined according to 1997 revised ACR and/or 2019 ACR/EULAR criteria. CV diagnosis was confirmed histologically and classified by using the dermatological addendum of the Chapel Hill classification. SLE activity and flare severity at the time of CV diagnosis were assessed independently of vasculitis items with the SELENA-SLEDAI and SELENA-SLEDAI Flare Index. RESULTS: Overall, 39 patients were included; 35 (90%) were female. Cutaneous manifestations included mostly palpable purpura (n = 21; 54%) and urticarial lesions (n = 18; 46%); lower limbs were the most common location (n = 33; 85%). Eleven (28%) patients exhibited extracutaneous vasculitis. A higher prevalence of Sjögren's syndrome (51%) was found compared with SLE patients without CV from the French referral centre group (12%, P < 0.0001) and the Swiss SLE Cohort (11%, P < 0.0001). CV was mostly classified as urticarial vasculitis (n = 14, 36%) and cryoglobulinaemia (n = 13, 33%). Only 2 (5%) patients had no other cause than SLE to explain the CV. Sixty-one percent of patients had inactive SLE. CONCLUSION: SLE-related vasculitis seems very rare and other causes of vasculitis should be ruled out before considering this diagnosis. Moreover, in more than half of patients, CV was not associated with another sign of active SLE.

RESUMEN

OBJECTIVE: Among specific autoantibodies in DM, the anti-small ubiquitin-like modifier activating enzyme (SAE) antibody is rare. We aim to describe the clinical characteristics, cancer prevalence, and muscle pathology of anti-SAE-positive DM. METHODS: Patients with a diagnosis of DM and sera positive for the anti-SAE antibody were recruited from 19 centres in this retrospective observational study. The available muscular biopsies were reviewed. We conducted a comparison with anti-SAE-negative DM and a review of the literature. RESULTS: Of the patients in the study (n = 49), 84% were women. Skin involvement was typical in 96% of patients, with 10% having calcinosis, 18% ulceration and 12% necrosis; 35% presented with a widespread skin rash. Muscular disease affected 84% of patients, with mild weakness [Medical Research Council (MRC) scale 4 (3, 5)], although 39% of patients had dysphagia. Muscular biopsies showed typical DM lesions. Interstitial lung disease was found in 21% of patients, mainly with organizing pneumonia pattern, and 26% of patients showed dyspnoea. Cancer-associated myositis was diagnosed in 16% of patients and was responsible for the majority of deaths, its prevalence being five times that of the general population. IVIG therapy was administered to 51% of the patients during the course of the disease. Comparison with anti-SAE-negative DM (n = 85) showed less and milder muscle weakness (P = 0.02 and P = 0.006, respectively), lower creatinine kinase levels (P < 0.0001) and less dyspnoea (P = 0.003). CONCLUSION: Anti-SAE positive DM is a rare subgroup associated with typical skin features but a potentially diffuse rash, a mild myopathy. Interstitial lung disease defines an organizing pneumonia pattern. Cancer associated DM prevalence is five times that of the general population.

RESUMEN

BACKGROUND: No study has assessed the risk factors of progression from discoid lupus erythematosus (DLE) to severe systemic lupus erythematosus (sSLE) (defined as requiring hospitalization and specific treatment). OBJECTIVE: To identify the risks factors of and generate a predicting score for progression to sSLE among patients with isolated DLE or associated with systemic lupus erythematosus with mild biological abnormalities. METHODS: In this registry-based cohort study, multivariable analysis was performed using risk factors identified from literature and pruned by backward selection to identify relevant variables. The number of points was weighted proportionally to the odds ratio (OR). RESULTS: We included 30 patients with DLE who developed sSLE and 134 patients who did not. In multivariable analysis, among 12 selected variables, an age of <25 years at the time of DLE diagnosis (OR, 2.8; 95% CI, 1.1-7.0; 1 point), phototype V to VI (OR, 2.7; 95% CI, 1.1-7.0; 1 point), and antinuclear antibody titers of ≥1:320 (OR, 15; 95% CI, 3.3-67.3; 5 points) were selected to generate the score. Among the 54 patients with a score of 0 at baseline, none progressed to sSLE, whereas a score of ≥6 was associated with a risk of approximately 40%. LIMITATIONS: Retrospective design. CONCLUSION: In our cohort, an age of <25 years at the time of DLE diagnosis, phototype V to VI, and antinuclear antibody titers of ≥1:320 were risk factors for developing sSLE.

RESUMEN

Extensive dermatophytosis caused by terbinafine-resistant Trichophyton indotineae harboring Phe397Leu and Leu393Ser substitutions in the squalene epoxidase enzyme was diagnosed in France. Analysis of internal transcribed spacer sequences revealed the wide spread of this species in Asia and Europe. Detection of T. indotineae in animals suggests their possible role as reservoirs.

RESUMEN

Skin reactions are well described complications of tattooing, usually provoked by red inks. Chemical characterizations of these inks are usually based on limited subjects and techniques. This study aimed to determine the organic and inorganic composition of inks using X-ray fluorescence spectroscopy (XRF), X-ray absorption spectroscopy (XANES) and Raman spectroscopy, in a cohort of patients with cutaneous hypersensitivity reactions to tattoo. A retrospective multicenter study was performed, including 15 patients diagnosed with skin reactions to tattoos. Almost half of these patients developed skin reactions on black inks. XRF identified known allergenic metals - titanium, chromium, manganese, nickel and copper - in almost all cases. XANES spectroscopy distinguished zinc and iron present in ink from these elements in endogenous biomolecules. Raman spectroscopy showed the presence of both reported (azo pigments, quinacridone) and unreported (carbon black, phtalocyanine) putative organic sensitizer compounds, and also defined the phase in which Ti was engaged. To the best of the authors' knowledge, this paper reports the largest cohort of skin hypersensitivity reactions analyzed by multiple complementary techniques. With almost half the patients presenting skin reaction on black tattoo, the study suggests that black modern inks should also be considered to provoke skin reactions, probably because of the common association of carbon black with potential allergenic metals within these inks. Analysis of more skin reactions to tattoos is needed to identify the relevant chemical compounds and help render tattoo ink composition safer.

RESUMEN

OBJECTIVES: Type-I interferons (IFNs-I) have potent antiviral effects. IFNs-I are also overproduced in patients with systemic lupus erythematosus (SLE). Autoantibodies (AAbs) neutralising IFN-α, IFN-ß and/or IFN-ω subtypes are strong determinants of hypoxemic COVID-19 pneumonia, but their impact on inflammation remains unknown. METHODS: We retrospectively analysed a monocentric longitudinal cohort of 609 patients with SLE. Serum AAbs against IFN-α were quantified by ELISA and functionally assessed by abolishment of Madin-Darby bovine kidney cell protection by IFN-α2 against vesicular stomatitis virus challenge. Serum-neutralising activity against IFN-α2, IFN-ß and IFN-ω was also determined with a reporter luciferase activity assay. SARS-CoV-2 antibody responses were measured against wild-type spike antigen, while serum-neutralising activity was assessed against the SARS-CoV-2 historical strain and variants of concerns. RESULTS: Neutralising and non-neutralising anti-IFN-α antibodies are present at a frequency of 3.3% and 8.4%, respectively, in individuals with SLE. AAbs neutralising IFN-α, unlike non-neutralising AAbs, are associated with reduced IFN-α serum levels and a reduced likelihood to develop active disease. However, they predispose patients to an increased risk of herpes zoster and severe COVID-19 pneumonia. Severe COVID-19 pneumonia in patients with SLE is mostly associated with combined neutralisation of different IFNs-I. Finally, anti-IFN-α AAbs do not interfere with COVID-19 vaccine humoral immunogenicity. CONCLUSION: The production of non-neutralising and neutralising anti-IFN-I antibodies in SLE is likely to be a consequence of SLE-associated high IFN-I serum levels, with a beneficial effect on disease activity, yet a greater viral risk. This finding reinforces the recommendations for vaccination against SARS-CoV-2 in SLE.

RESUMEN

OBJECTIVE: The detection of somatic mutations among the genes of myeloid cells in asymptomatic patients-defining clonal haematopoiesis of indeterminate potential (CHIP)-is associated with a predisposition to cardiovascular events (CVEs) in the general population. We aimed to determine whether CHIP was associated with CVEs in SLE patients. METHODS: The study is an ancillary study of the randomized, double-blind, placebo-controlled, multicentre PLUS trial conducted from June 2007 through August 2010 at 37 centres in France, involving 573 SLE patients. The search for somatic mutations by high-throughput sequencing of 53 genes involved in clonal haematopoiesis was performed on genomic DNA collected at PLUS inclusion. CHIP prevalence was assessed in SLE and in a retrospective cohort of 479 patients free of haematological malignancy. The primary outcome was an incident CVE in SLE. RESULTS: Screening for CHIP was performed in 438 SLE patients [38 (29-47) years, 91.8% female]. Overall, 63 somatic mutations were identified in 47 patients, defining a CHIP prevalence of 10.7% in SLE. Most SLE patients (78.7%) carried a single mutation. Most variants (62.5%) were located in the DNMT3A gene. CHIP frequency was related to age and to age at SLE diagnosis, and was associated with a lower frequency of aPLs. CHIP occurred >20 years earlier (P < 0.00001) in SLE than in controls. The detection of CHIP at inclusion was not found to be associated with occurrence of CVEs during follow-up [HR = 0.42 (0.06-3.21), P = 0.406]. CONCLUSION: The prevalence of CHIP is relatively high in SLE for a given age, but was not found to be associated with incident CVEs.

RESUMEN

The word lupus (Latin term for the wolf) was used indistinctively since the Middle Ages for several types of diseases characterized by ulcerous lesions, mainly in the lower limbs. In the middle of the 18th century, the French dermatologist Cazenave mentioned for the first time the term "lupus érythémateux," while Kaposi reported discoid lupus as a separate entity. The true turning point in the history of lupus occurred at the beginning of the 19th century, when the distinction between lupus vulgaris and cutaneous lupus in its modern sense emerged slowly. Major subsequent contributions from Kaposi, Sequiera and Balean, and Osler enabled the recognition of the systemic nature of the disease, with its modern history being marked by the recognition of DNA as the main target of antinuclear antibodies and the central role of interferons. Although many nonpharmacologic treatments have been used throughout the ages, glucocorticoids, hydroxychloroquine, and immunosuppressive agents mainly appeared in the second half of the 20th century. The beginning of the 21st century is now characterized by an in-depth understanding of the pathogenesis of the disease and the appearance of biologic and targeted treatments, paving the way for a better care of lupus patients.

RESUMEN

BACKGROUND: Little is known about the prevalence and factors associated with long-term remission in cutaneous lupus erythematosus (CLE). OBJECTIVES: To assess the prevalence, the factors associated with remission, and the long-term remission with and without treatment during CLE. METHODS: Longitudinal cohort study including biopsy-proven patients with CLE seen between November 1, 2019 and April 30, 2021, with at least 6 months of follow-up after diagnosis. Demographic data, CLE subtypes, remission status, and treatments were recorded. Remission was defined by a Cutaneous Lupus Erythematosus Disease Area and Severity Index activity score of 0. Long-term remission was defined by remission >3 years. RESULTS: Among 141 patients included (81% of women), 93 (66%) were in remission at last follow-up with a median duration since diagnosis of 11.4 years (interquartile range, 4.2-24.7). Long-term remission was observed in 22 (19%) of 114 patients with at least 3 years of follow-up, including 5 (4.4%) with no systemic treatment. Active smoking (odds ratio, 0.22 [95%CI: 0.05-0.97]; P = .04) and discoid CLE lesions (odds ratio, 0.14 [95%CI, 0.04-0.48]; P = .004) were associated with a lower risk of long-term remission. LIMITATIONS: Partial retrospective data collection and tertiary center population. CONCLUSION: Long-term remission is rare in CLE and negatively associated with active smoking and discoid CLE.

RESUMEN

BACKGROUND: Cutaneous polyarteritis nodosa is a form of medium-sized vessel vasculitis. Despite a disabling and prolonged course, data on treatment efficacy and safety remain scarce. OBJECTIVES: We aimed to describe treatment efficacy and safety in patients with cutaneous polyarteritis nodosa. METHODS: This multicenter retrospective, observational study, recorded clinical and biologic data together with treatments received. The primary outcome was the rate of complete response at month 3. Secondary outcomes assessed drug survival and safety. RESULTS: We included 68 patients who received a median of 2 therapeutic lines (interquartile range, 1-3). Overall, complete response was achieved in 13 of 42 (31%) patients with colchicine, 4 of 17 (23%) with dapsone, 11 of 25 (44%) with glucocorticoids (GCs) alone, 1 of 9 (11%) with nonsteroidal anti-inflammatory drugs, 11 of 13 (84%) with GCs+azathioprine, and 7 of 15 (47%) with GCs+methotrexate. GCs+azathioprine had the best drug survival (median duration, 29.5 months; interquartile range, 19.5-36.0). Response at month 3 was decreased with peripheral neurologic involvement (odds ratio, 0.19; 95% confidence interval, 0.03-0.81; P = .04). Overall, the rate of treatment-related adverse events was 18%, which led to the discontinuation of treatment in 7% of patients. LIMITATION: Retrospective study. CONCLUSION: Colchicine seems to confer good benefit-risk balance in cutaneous polyarteritis nodosa without peripheral sensory neuropathy. GCs+azathioprine seem the best treatment in the event of relapse.

RESUMEN

BACKGROUND: The COVID-19 outbreak has dramatically impacted medical education, both bedside and academic teaching had to be adapted to comply with the reorganisation of care and social distancing measures. OBJECTIVES: To overview the impact of the pandemic on medical education, including the pedagogical responses adopted and their assessment by medical students and residents. MATERIAL AND METHODS: This restricted systematic review was performed using Rayyan QCRI, to select observational or interventional articles and field experience reports assessing the impact of the COVID-19 pandemic on medical education for medical students and residents. Study design, study population, geographical origin, use of an educational tools (including softwares and social media), their type and assessment, were recorded. For studies evaluating a specific tool the Medical Education Research Study Quality Instrument (MERSQI) was used to assess study quality. RESULTS: The literature search identified 1480 references and 60 articles were selected. Most articles focused on residents (41/60; 69%), and half (30/60; 50%) involved surgical specialties. Online courses were the most frequently used pedagogical tool (52/60; 88%). Simulation tools were used more frequently in articles involving surgical specialties (15/29; 52%) compared with medical specialties (2/14; 12%) (p=0.01). Only four studies reported the assessment of pedagogical tools by medical students, their MERSQI scores ranged from 5.5/18 to 9.0/18. CONCLUSION: Medical education was highly impacted by the COVID-19 pandemic particularly in surgical specialties. Online courses were the most frequently attempted solution to cope with social distancing constraints. Medical students' assessment of pedagogical tools was mostly positive, but the methodological quality of those studies was limited.

RESUMEN

OBJECTIVE: Identification of biological markers able to better stratify cardiovascular risks in SLE patients is needed. We aimed to determine whether serum cardiac troponin T (cTnT) levels measured with a highly sensitive assay [high sensitivity cTnT (HS-cTnT)] may predict cardiovascular events (CVEs) in SLE. METHOD: All SLE patients included between 2007 and 2010 in the randomized, double-blind, placebo-controlled, multicentre PLUS trial were screened. Patients with no past history of CVE at inclusion and a follow-up period of >20 months were analysed. HS-cTnT concentration was measured using the electrochemiluminescence method on serum collected at PLUS inclusion. The primary outcome was the incident CVE. Factors associated with the primary outcome were identified and multivariate analysis was performed. RESULTS: Overall, 442 SLE patients (of the 573 included in the PLUS study) were analysed for the primary outcome with a median follow up of 110 (interquartile range: 99-120) months. Among them, 29 (6.6%) experienced at least one CVE that occurred at a median of 67 (interquartile range: 31-91) months after inclusion. Six out of 29 patients had more than one CVE. In the multivariate analysis, dyslipidaemia, age and HS-cTnT were associated with the occurrence of CVE. Kaplan-Meier analysis showed that a concentration of HS-cTnT > 4.27 ng/l at inclusion increased by 2.7 [hazard ratio 2.7 (95% CI: 1.3, 5.6), P =0.0083] the risk of CVE in SLE. CONCLUSION: HS-cTnT measured in serum is the first identified biomarker independently associated with incident CVE in SLE patients.

RESUMEN

BACKGROUND: Differential diagnosis between cutaneous lupus erythematosus (CLE) and dermatomyositis (DM) may be challenging if digital lesions occur. OBJECTIVES: To compare nailfold capillaroscopy (NFC) findings in CLE patients with or without digital involvement, and to compare capillaroscopic findings between CLE patients with digital lesions and DM patients. METHODS: Prospective monocentric study including CLE and DM patients. NFC was performed and standardized items were recorded. RESULTS: Fifty-one CLE patients and 10 DM patients with digital lesions were included. A scleroderma pattern was found in 6 patients (12%): in 5 out of 17 patients with digital lesions, compared with only 1 out of 34 patients without digital lesions (p = 0.01). In multivariate analysis, CLE digital lesions and digital ulcerations were statistically associated with scleroderma pattern. CLE digital lesions were significantly associated with architectural disorganization (p = 0.0003) and capillary rarefaction (p = 0.0038). A scleroderma pattern was significantly more frequent in DM patients (80%) than in CLE patients with digital lesions (30%, p = 0.018). Capillaroscopic findings were not significantly different between CLE patients with digital lesions and DM patients. CONCLUSION: Although scleroderma pattern is more frequent in DM patients than in CLE patients with digital lesions, NFC cannot formally distinguish CLE from DM.

RESUMEN

INTRODUCTION: Kikuchi-Fujimoto disease (KFD) is a self-limited histiocytic necrotizing lymphadenitis sometimes affecting the skin. "Kikuchi disease-like inflammatory pattern" (KLIP) has been described in cutaneous lesions as similar pathological features in patients without lymph node involvement and as a potential clue for the diagnosis of lupus. We aimed to describe KLIP-associated clinical and immunological features in lupus patients with a retrospective case-control study. METHODS: Thirteen cases of KLIP were included as well as thirty-nine age- and sex-matched control lupus patients without KLIP. At the time of KLIP diagnosis, 4/13 patients (31%) had isolated cutaneous lupus erythematosus (CLE) and 9/13 had (69%) systemic lupus erythematosus (SLE) including 6 (46%) with severe haematological, lung, cardiac or renal disease. KLIP features were observed in skin biopsies of different clinical presentations. RESULTS: Compared with our control group, KLIP patients more frequently had SLE 9/13 (69%) versus 8/39 (21%) (OR 12.9; IC95% [2.86-58.2]; p = 0.0004) and more frequently severe SLE. Two out of four CLE exhibiting KLIP lesions (50%) developed severe SLE with cardiac or renal involvement after 12 and 24 months, respectively.Treatment with thalidomide 100 mg/day allowed rapid and complete clearance of cutaneous lesions in 6/6 KLIP patients. The need to use thalidomide tended to be more frequent in KLIP patients than in controls. CONCLUSION: Our study suggests that KLIP features in lupus skin lesions are associated with SLE and severe systemic features. Despite a limited number of isolated CLE patients with KLIP features in the skin, this observation may warrant closer follow-up on patients with a higher risk of developing SLE.

RESUMEN

OBJECTIVE: Pruritus is an important symptom frequently accompanying various inflammatory skin conditions and some recent data indicated that it may be associated with autoimmune connective tissue diseases. The aim of this study was to assess the frequency and clinical presentation of itch in CLE. METHODS: A multinational, prospective, cross-sectional study was performed to assess the prevalence, intensity and clinical characteristic of pruritus in various subtypes of CLE. A total of 153 patients with active CLE lesions were included. Their age ranged between 17 and 82 years (mean 49.8 ± 15.4 years), and 115 patients (75.2%) were women. The disease activity and damage were assessed according to the Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI). Pruritus severity was assessed with Numeric Rating Scale (NRS) and the 12-Item Pruritus Severity Scale. Dermatology Life Quality Index and EQ-5D questionnaire were used to measure quality of life. RESULTS: Pruritus was present in 116 (76.8%) of patients of whom half had NRS scoring equal or above 4 points indicating moderate or severe pruritus. Most commonly itch was localized on the scalp, face (excluding ears and nose) and arms (40.5%, 36.2%, 31.9%, respectively). Sensations connected with pruritus were most frequently described as burning, tingling and like ants crawling feeling, but 31.9% patients described it as "pure itch". More than half of patients reported that pruritus was present every day, and it was most frequent during the evenings. The pruritus scoring and the CLASI activity score were significantly correlated (r = 0.42, p = 0.0001), while no correlation was found with the CLASI damage score (p = 0.16). Both the maximum and average itch intensity were correlated with systemic lupus erythematosus (SLE) activity measured with the Systemic Lupus Erythematosus Disease Activity Index. CONCLUSIONS: Pruritus is a common, but frequently overlooked symptom of CLE. Its intensity correlates with the activity of CLE, but not with the skin damage. In more than a half of patients it occurs on a daily basis. The correlation between the intensity of pruritus and the activity of the skin lesions and the systemic involvement indicate that pruritus could be an individual indicator of both SLE and CLE activity.

RESUMEN

BACKGROUND: Severe onychomycosis treatment in kidney transplant recipients (KTR) is challenging because of drug interactions and adverse events. Tacrolimus remains the antirejection treatment (ART) of choice in kidney transplantation but tolerance with systemic terbinafine for the management of severe onychomycosis has not been studied. OBJECTIVE: This study illustrates severe onychomycosis management in a kidney transplantation setting and investigates systemic terbinafine tolerance profile in KTR. PATIENTS/METHODS: We retrospective analysed clinical data of KTR with a confirmed diagnosis of severe onychomycosis. RESULTS: We retrieved a total of 29 KTR with severe onychomycosis needing an oral treatment to manage onychomycosis. In 55.1% (16/29) KTR, altered renal biological parameters or lack of guidelines to manage severe onychomycosis were the main reasons to deterring clinicians from prescribing oral treatments. 13 patients received an oral terbinafine treatment (9, 3 and 1 with a tacrolimus, cyclosporine and everolimus-based ART, respectively). Clinical and biological follow-up did not reveal severe drug interactions. ART blood levels showed significant variations in 2 patients without clinical consequences in renal graft. Two patients reported mild adverse events but after only one dose of terbinafine. Using an open-source image analysis program, clinical evolution of onychomycosis could be retrospectively quantified and followed up. CONCLUSIONS: The results presented here suggest that oral terbinafine can be proposed to treat severe onychomycosis with an acceptable tolerance profile in KTR with different ART such as tacrolimus and highlight the need of multicentric studies to establish guidelines for onychomycosis treatment in KTR.

RESUMEN

OBJECTIVES: In SLE, heterogeneous clinical expression and activity may reflect diverse pathogenic and/or effector mechanisms. We investigated SLE heterogeneity by assessing the expression of three gene sets representative of type I IFN (IFN-I), polymorphonuclear neutrophil (PMN) and plasmablast (PB) signatures in a well-characterized, multidisciplinary cohort of SLE patients. We further assessed whether individual gene products could be representative of these three signatures. METHODS: Whole blood, serum and clinical data were obtained from 140 SLE individuals. Gene expression was assessed by NanoString technology, using a panel of 37 probes to compute six IFN-I, one PMN and one PB scores. Protein levels were measured by ELISA. RESULTS: Depending on the score, 45-50% of SLE individuals showed high IFN-I gene expression. All six IFN-I scores were significantly associated with active skin involvement, and two of six were associated with arthritis. IFN-induced Mx1 protein (MX1) level was correlated with IFN-I score (P < 0.0001) and associated with a similar clinical phenotype. In all, 25% of SLE individuals showed high PMN gene expression, associated with SLE fever, serositis, leukopoenia and glucocorticoid use. PB gene expression was highly affected by immunosuppressant agents, with no association with SLE features. Combined IFN-I and PMN gene scores were significantly associated with high disease activity and outperformed anti-dsDNA and anti-C1q autoantibody and complement levels for predicting SLE activity. CONCLUSION: IFN-I and PMN gene scores segregate with distinct SLE clinical features, and their combination may identify high disease activity. MX1 protein level performed similar to IFN-I gene expression.
