Gastrointestinal disorders in systemic sclerosis: cluster analysis and prognosis from a French prospective cohort.

OBJECTIVES: The gastrointestinal tract (GIT) is frequently involved in systemic sclerosis (SSc) and is responsible for alteration of quality of life. Many complications can occur, including chronic intestinal pseudo-obstruction, digestive haemorrhage and small-intestinal bacterial overgrowth. Since early development of organ failure is associated with poor prognosis, we need to identify risk factors associated with severe GIT involvement to prevent severe forms of the disease. METHODS: We conducted an observational prospective study, which included 90 SSc patients from December 2019 to September 2021. We collected questionnaires about digestive manifestations and quality of life, blood and stool samples, and performed imaging. At inclusion and throughout the study we assessed the occurrence of malnutrition and severe GIT disorders. We performed statistical analysis to highlight eventual risk factors associated with digestive manifestations, including hierarchical cluster analysis. RESULTS: A majority of our patients had gastro-oesophageal manifestations (93.3%), followed by intestinal manifestations (67.8%) and anorectal manifestations (18.9%). We found a correlation between anorectal disorders and cardiac disease, and between gastro-oesophageal involvement and impaired pulmonary function tests. Smoking was significantly associated with occurrence of severe GIT disorders. Malnutrition was frequent and associated with more cardiac and pulmonary disease. Cluster analysis identified three groups of patients, including one cluster with cardiac and digestive involvement. CONCLUSIONS: GIT manifestations are frequent and severe in SSc. Smoking appears to be associated with severe disease. Anorectal manifestations may be associated with cardiac disease, but we need more studies to validate these results.

Nailfold dermoscopy predicts the absence of a capillaroscopy sclerodermic pattern: The multicentre, prospective VASCUL-R trial.

BACKGROUND: Nailfold capillaroscopy is recommended to diagnose primary or secondary Raynaud's phenomenon (RP). Capillaroscopy is normal in primary RP, which is the most frequent. Screening for RP capillary anomalies with nailfold dermoscopy has been promising. OBJECTIVE: To determine whether normal nailfold dermoscopy-based on the absence of five criteria that define a sclerodermic pattern-is able to predict normal capillaroscopy with good positive-predictive value (PPV). METHODS: Prospective, 2-phase (monocentre and multicentre) study on patients at first consultation for RP undergoing nailfold video capillaroscopy (NVC) and nailfold dermoscopy by two different 'blinded' trained observers, respectively, a vascular specialist and a dermatologist, not familiar with capillaroscopy. The five criteria noted were as follows: disorganization, megacapillaries, low capillary density, avascular areas and haemorrhages. RESULTS: Based on 105 patients, the dermoscopy PPV for a normal NVC was 100% (p = 0.015), with 37.9% sensitivity, when no criterion was observed. Excluding haemorrhages, the PPV remained 100% (p < 0.0001), with sensitivity rising to 73.7% and 100% specificity. CONCLUSION: Normal nailfold dermoscopy with the absence of four easy-to-observe criteria predicts normal NVC with an excellent PPV.

Severe Scabies: A French Multi-centre Study Involving 95 Patients with Crusted and Profuse Disease and Review of the Literature.

The aim of this multi-centre French retrospective study was to identify severe, i.e. crusted and profuse, scabies patients. Records were retrieved from 22 Dermatology or Infectious Diseases departments in the Ile-de-France from January 2009 to January 2015 to characterize epidemiology, demography, diagnosis, contributing factors, treatment features, and outcomes in severe scabies. A total of 95 inpatients (57 crusted and 38 profuse) were included. A higher number of cases was observed among elderly patients (>75 years), mostly living in institutions. Thirteen patients (13.6%) reported a history of previously treated scabies. Sixty-three patients (66.3%) had been seen by a previous practitioner for the current episode (up to 8 previous visits). Initial misdiagnosis (e.g. eczema, prurigo, drug-related eruptions, psoriasis) was documented in 41 patients (43.1%). Fifty-eight patients (61%) had already received 1 or more previous treatments for their current episode. Forty percent received corticosteroids or acitretin for an initial diagnosis of eczema or psoriasis. Median time from the onset of symptoms to the diagnosis of severe scabies was 3 months (range 0.3-22). Itch was present in all patients at diagnosis. Most patients (n=84, 88.4%) had comorbidities. Diagnostic and therapeutic approaches varied. Complications occurred in 11.5% of cases. To date, there is no consensus for diagnosis and treatment, and future standardization of is required for optimal management.

Aetiological treatment of venous leg ulcers with compression therapy: real-life outcomes with two different procedures.

OBJECTIVE: To evaluate the healing outcomes and costs associated with the aetiological management of venous leg ulcers (VLUs) treated with recommended multicomponent bandages (MCBs) and short-stretch bandages (SSBs). METHOD: This observational study is a retrospective comparative study (Level 2b), based on the French administrative healthcare database (Système National des Données de Santé, SNDS). It includes patients treated from onset with reimbursed MCBs and SSBs for a VLU episode, between July 2018 and September 2020. Although other compression systems, such as long-stretch bandages, are commonly used for the treatment of VLUs, they are not recommended by health authorities in France and thus, were not considered for this study. A binomial regression model was performed to estimate the adjusted relative risk of wound closure rates at three months for each group, based on potential confounding factors including, notably, age, sex, key comorbidities, and wound dressing size. The mean healthcare cost was calculated for patients whose VLUs healed within the study period. RESULTS: The reimbursement data (including prescribed compression systems and nursing care) of the 25,255 selected patients were analysed in the study. There were no significant differences between the MCBs and SSBs groups when considering patient characteristics. The healing rates after three months' treatment, were 42% and 35% (p<0.001) in the MCBs and SSBs groups, respectively. When adjusting the statistical model, the chance of healing at three months was still 12% higher with MCBs compared with SSBs (p<0.0001). The median healing time was estimated at 115 (interquartile range (IQR): 60-253) days in the MCB group versus 137 (IQR: 68-300) days in the SSBs group. The average treatment cost per patient with a healed ulcer was €2875±3647 in the MCB group and €3580±5575) in the SSBs group (p=0.0179), due to lower hospital stay and nursing costs in the MCB group. Differences in wound characteristics between the two groups cannot be totally excluded, due to the limited content of the database in terms of clinical data, but should have been addressed, to some extent, through the study selection criteria and the chosen regression model. CONCLUSION: In this study, this SNDS analysis seemed to confirm that the healing outcomes achieved in real-life with MCBs were in line with those reported in clinical trials, and superior to SSBs, which reinforces the current position from the guidelines.

Correlation of nailfold capillaroscopy findings with history of digital ulcer on same finger: Results of SCLEROCAP study.

Systemic sclerosis may be complicated by digital ulcers. Nailfold capillaroscopy on one finger might reflect an increased risk of digital ulcer (DU). In the present study we studied the correlations between a history of ulcer and capillary findings on the finger. METHOD: This study is part of Sclerocap, a multicenter study aiming at validating prospectively the prognostic value of Maricq's and Cutolo's capillaroscopic classifications during a three-year longitudinal follow-up. A history of past or present digital ulcer was recorded at inclusion and nailfold capillaroscopy was performed. Elementary findings as well as Cutolo and Maricq's classifications were assessed. RESULTS: 387 patients were included in Sclerocap (327 females, 60 males) and 3096 fingers were examined by capillaroscopy at inclusion: 316 fingers (10%) belonging to 113 patients had a history of DU. Late Cutolo's stage was statistically correlated with a history of DU, both by univariate: OR 2.08 [1.09-3.96] and multivariate analysis: OR 1.97 [1.06-3.63]. Among the elemental abnormalities, only edema and decreased capillary density were correlated with a history of DU by multivariate analysis: respectively OR 1.92 [1.17-3.16] and 0.65 [0.49-0.85]. CONCLUSION: This cross-sectional study in a large cohort of patients with systemic sclerosis shows a correlation between a history of digital ulcer and edema, a decrease in capillary density and the late stage in Cutolo's classification. The extent of capillary abnormalities on one finger is associated with a history of local digital ulcer. Capillaroscopy might be used to predict the risk of DU but these results need first to be confirmed by prospective studies.

Prevalence and factors associated with long-term remission in cutaneous lupus: A longitudinal cohort study of 141 cases.

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.

A new compression system for treatment of venous leg ulcers: a prospective, single-arm, clinical trial (FREEDOM).

OBJECTIVE: To evaluate the efficacy, tolerability and acceptability of a new multicomponent compression system in one bandage for the local treatment of patients with venous leg ulcers (VLUs). METHOD: This was an international, prospective, non-comparative, clinical trial, conducted in France and Germany. Eligible participants had a VLU with a wound area of 2-20cm2, lasting for a maximum of 24 months. For a period of 6 weeks, patients were treated with a new multicomponent compression system in one bandage which was worn day and night, providing high working pressure and moderate resting pressure (UrgoK1). Clinical assessments, wound measurement and photographs were planned at weeks 1, 2, 4 and 6. The primary endpoint was the relative wound area reduction (RWAR) after 6 weeks of treatment. Secondary endpoints included wound closure rate, oedema resolution, change in patient's health-related quality of life (HRQoL), acceptability, adherence to the compression therapy, local tolerance, and physician's overall satisfaction with the evaluated compression system. RESULTS: A cohort of 52 patients (52% female, mean age 75.4±13.0 years) with VLUs, including oedema in 58% of cases, were recruited from 22 centres. At baseline, 42 patients had already been treated with a different compression system. VLUs had been present for 5.6±4.9 months and had a mean area of 5.7±4.3cm2. After 6 weeks of treatment, a median RWAR of 91% (interquartile range: 39.4; 100.0) was achieved. Wound closure was reported in 35% of patients. A RWAR ≥40% at week 4, predictive of wound healing at 12 weeks, was achieved in 62% of patients. At the final visit, oedema present at baseline was resolved in 57% of patients. Substantial improvements in the HRQoL of the patients were reported with a decrease of the pain/discomfort and anxiety/depression dimensions. Comfort in wearing the evaluated system was reported as 'very good' or 'good' by 79% of patients, resulting in a high patient adherence to compression therapy. Compared to previous compression systems, half of the patients reported more ease in wearing shoes, and greater satisfaction and comfort with this new system. Nine non-serious adverse events related to the device or its procedure occurred in seven patients. At the final visit, the majority of the physicians were 'very satisfied' or 'satisfied' with the new compression system overall. CONCLUSION: The new multicomponent compression system in one bandage has been shown to promote rapid healing of VLUs, reduce oedema, improve HRQoL and to be well tolerated and accepted. It appears to be a viable alternative to existing compression systems.

Nailfold capillaroscopy findings in cutaneous lupus erythematosus patients with or without digital lesions and comparison with dermatomyositis patients: A prospective study.

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.

Cutaneous Kikuchi disease-like inflammatory pattern without lymph node involvement is associated with systemic disease and severe features in lupus erythematous: A case-control study.

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.

Severe onychomycosis management with oral terbinafine in a kidney transplantation setting: Clinical follow-up by image analysis.

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.

Optimizing finger systolic blood pressure measurements with laser Doppler: Validation of the second phalanx site.

OBJECTIVE: Finger systolic blood pressure measurement (FSBP) has been shown helpful in the detection of distal arterial insufficiency in upper limbs. This work assesses the possibility to measure FSBP on the 2nd phalanx instead of the first one in order to improve its sensitivity and to verify this would not alter the repeatability of the measurement. METHODS: In this multicenter study, FSBP was measured twice in all fingers but the thumbs in consecutive systemic sclerosis patients on the first phalanx and the second phalanx in alternate order using laser-Doppler flowmetry. RESULTS: Thirty-seven patients were enrolled. The repeatability of FSBP was excellent and similar on the first and 2nd phalanxes with coefficients of variation respectively of 7.1% and 7.6%. While the correlation between the FSBP at the two sites was fair (Pearson coefficient 0.69; p < 0.001). The agreement was poor, with a mean difference of 14 mm Hg between the two sites. Significantly higher differences were found in fingers with digital ulcers. The ROC curves showed a better prediction of the 2nd phalanx measurements. CONCLUSION: FSBP has an excellent repeatability whatever the site of phalanx. However, measurements performed on the 2nd phalanx have a better sensitivity for the prediction of digital ulcers.

Treatment of calcinosis cutis in systemic sclerosis and dermatomyositis: A review of the literature.

BACKGROUND: We have limited data on the treatment of calcinosis cutis associated with systemic sclerosis and dermatomyositis. OBJECTIVE: To assess the efficacy and tolerance of available treatments for calcinosis cutis based on previously published studies. METHODS: We performed a systematic review of studies published in Medline, Embase, and the Cochrane library during 1980-July 2018. The strength of clinical data was graded according to the modified Oxford Centre for Evidence-Based Medicine levels of evidence. RESULTS: In all, 30 studies (288 patients) were included. Eleven therapeutic classes, surgery, and physical treatments were identified as potential treatment options for calcinosis cutis. On the basis of results of a small randomized controlled trial and 4 retrospective studies, low-dose warfarin should not be used for calcinosis cutis (level IB evidence). The results of several studies suggest diltiazem and bisphosphonates might be useful treatment options (level IV). Considering biologic therapies, rituximab has shown promising results in treating both dermatomyositis and systemic sclerosis, whereas tumor necrosis factor inhibitors might be useful for treating juvenile dermatomyositis (level IV). Intralesional sodium thiosulfate might be a promising alternative (level IV). LIMITATIONS: Few included studies had a high level of evidence. CONCLUSION: This study highlights the efficacy and tolerance profiles of available treatments for calcinosis cutis, with a focus on level of evidence.

Ockham's razor defeated: about two atypical cases of hemolytic uremic syndrome.

BACKGROUND: Medical investigation is a favorite application of Ockham's razor, in virtue of which when presented with competing hypotheses, the solution with the fewest assumptions should be privileged. Hemolytic uremic syndrome (HUS) encompasses diseases with distinct pathological mechanisms, such as HUS due to shiga-like toxin-producing bacteria (STEC-HUS) and atypical HUS, linked to defects in the alternate complement pathway. Other etiologies such as Parvovirus B19 infection are exceptional. All these causes are rare to such extent that we usually consider them mutually exclusive. We report here two cases of HUS that could be traced to multiple causes. CASES PRESENTATION: Case 1 presented as vomiting and diarrhea. All biological characteristics of HUS were present. STEC was found in stool (by PCR and culture). After initial remission, a recurrence occurred and patient was started on Eculizumab. Genetic analysis revealed the heterozygous presence of a CFHR1/CFH hybrid gene. The issue was favorable under treatment. In case 2, HUS presented as fever, vomiting and purpura of the lower limbs. Skin lesions and erythroblastopenia led to suspect Parvovirus B19 primo-infection, which was confirmed by peripheral blood and medullar PCR. Concurrently, stool culture and PCR revealed the presence of STEC. Evolution showed spontaneous recovery. CONCLUSIONS: Both cases defy Ockham's razor in the sense that multiple causes could be traced to a single outcome; furthermore, they invite us to reflect on the physiopathology of HUS as they question the classical distinction between STEC-HUS and atypical HUS. We propose a two-hit mechanism model leading to HUS. Indeed, in case 1, HUS unfolded as a result of the synergistic interaction between an infectious trigger and a genetic predisposition. In case 2 however, it is the simultaneous occurrence of two infectious triggers that led to HUS. In dissent from Ockham's razor, an exceptional disease such as HUS may stem from the sequential occurrence or co-occurrence of several rare conditions.

Circulating follicular helper T cells are increased in systemic sclerosis and promote plasmablast differentiation through the IL-21 pathway which can be inhibited by ruxolitinib.

OBJECTIVES: Systemic sclerosis (SSc) is an autoimmune disease characterised by widespread fibrosis, microangiopathy and autoantibodies. Follicular helper T (Tfh) cells CD4+CXCR5+PD-1+ cooperate with B lymphocytes to induce the differentiation of plasmocytes secreting immunoglobulins (Ig). Circulating Tfh (cTfh) cells are increased in several autoimmune diseases. However, there are no data about cTfh cells and their interaction with B cells in SSc. The aim of this study was to perform a quantitative and functional analysis of cTfh cells in SSc. METHODS: Using flow cytometry, we analysed cTfh cells from 50 patients with SSc and 32 healthy controls (HC). In vitro coculture experiments of sorted cTfh and B cells were performed for functional analysis. IgG and IgM production were measured by ELISA. RESULTS: We observed that cTfh cell numbers are increased in patients with SSc compared with HC. Furthermore, the increase in cTfh cells was more potent in patients with severe forms of SSc such as diffuse SSc and in the presence of arterial pulmonary hypertension. cTfh cells from patients with SSc present an activated Tfh phenotype, with high expression of BCL-6, increased capacity to produce IL-21 in comparison with healthy controls. In vitro, cTfh cells from patients with SSc had higher capacity to stimulate the differentiation of CD19+CD27+CD38hi B cells and their secretion of IgG and IgM through the IL-21 pathway than Tfh cells from healthy controls. Blocking IL-21R or using the JAK1/2 inhibitor ruxolitinib reduced the Tfh cells' capacity to stimulate the plasmablasts and decreased the Ig production. CONCLUSIONS: Circulating Tfh cells are increased in SSc and correlate with SSc severity. The IL-21 pathway or JAK1/2 blockade by ruxolitinib could be a promising strategy in the treatment of SSc.

Correlation between capillaroscopic classifications and severity in systemic sclerosis: results from SCLEROCAP study at inclusion.

OBJECTIVES: We assessed the correlation between severity of systemic sclerosis (SSc) and current staging systems based on nailfold capillaroscopy. METHODS: SCLEROCAP is a multicenter prospective study including consecutive scleroderma patients who have a yearly routine follow-up with capillaroscopy and digital blood pressure measurement. Capillaroscopy images were read by two observers blinded from each other, then by a third one in the case of discordance. A follow-up of 3 years is planned. The present study assessed the correlation between severity of systemic sclerosis (SSc) and current staging systems based on nail fold capillaroscopy at enrollment in the SCLEROCAP study. Univariate and multivariate logistic regression analysis was performed for both the Maricq and Cutolo classifications. RESULTS: SCLEROCAP included 387 patients in one year. Maricq's active and Cutolo's late classifications were very similar. In multivariate analysis, the number of digital ulcers (OR for 2 ulcers or more, respectively 2.023 [1.074-3.81] and 2.596 [1.434-4.699]) and Rodnan's skin score >15 (OR respectively 32.007 [6.457-158.658] and 18.390 [5.380-62.865]) correlated with Maricq's active and Cutolo's late stages. Haemoglobin rate correlated with Cutolo's late stage (hemoglobin<100 vs. >120 g/dl: OR 0.223 [0.051-0.980]), and total lung capacity with Maricq's active one: increase in 10%: OR0.833 [0.717-0.969]. CONCLUSIONS: The correlations found between capillaroscopy and severity of SSc are promising before the ongoing prospective study definitively assesses whether capillaroscopy staging predicts complications of SSc. Only two capillaroscopic patterns seem useful: one involving many giant capillaries and haemorrhages and the other with severe capillary loss.

Meningococcal purpura fulminans and severe myocarditis with clinical meningitis but no meningeal inflammation: a case report.

BACKGROUND: During fulminant meningococcal septicaemia, meningococci are often observed in the cerebrospinal fluid (CSF) although the patients have frequently no meningeal symptoms. Meningococcal meningitis, by contrast, usually features clinical meningeal signs and biochemical markers of inflammation with elevated white blood cell count (pleiocytosis) in the CSF. Cases of typical symptomatic meningitis without these biochemical features are uncommon in adults. CASE PRESENTATION: A 21-year-old male presented with meningococcal purpura fulminans and disseminated intravascular coagulation (DIC) associated with multiple organ dysfunction syndrome requiring hospitalization in the Intensive Care Unit. Despite typical meningeal clinical signs, lumbar puncture showed no pleiocytosis, normal glycorachia and normal proteinorachia, whereas the lactate concentration in the CSF was high (5.8 mmol/L). CSF culture showed a high inoculum of serogroup C meningococci. On day 2, after initial improvement, a recurrence of hypotension led to the diagnosis of acute meningococcal myocarditis, which evolved favourably within a week. During the hospitalization, distal ischemic and necrotic lesions were observed, predominantly on the fingertips, which were treated with local and systemic vasodilators. CONCLUSIONS: We report a rare case of adult meningococcal disease characterized by an intermediate form of meningitis between purulent meningitis and meningeal inoculation from fulminant meningococcal septicaemia, without classical signs of biological inflammation. It highlights the diagnostic value of CSF lactate, which may warrant administration of a meningeal dosing regimen of beta-lactam antibiotics. This case also demonstrates the potential severity of meningococcal myocarditis; we discuss its pathophysiology, which is distinct from other sepsis-related cardiomyopathies. Finally, the observed effects of vasodilators on the meningococcal skin ischemia in this case encourages future studies to assess their efficacy in DIC-associated necrosis.

Cutaneous Arteriolosclerosis Is Not Specific to Ischemic Hypertensive Leg Ulcers.

BACKGROUND: The histological characteristic of hypertensive leg ulcers (HLU) is the presence of "arteriolosclerosis." The pertinence of performing a skin biopsy to diagnose HLU is questionable, as cutaneous arteriolosclerosis may be related to patient comorbidities. The objective here was to evaluate the frequency of arteriolosclerosis in skin leg biopsies performed in patients without ulcer and in control patients with HLU. METHODS: We performed a retrospective study between January 2013 and July 2014. Patients were included if they had undergone a deep skin biopsy on the lower limbs, in the absence of any leg ulcer. Controls were patients with typical HLU. RESULTS: Fifty-eight patients and 6 controls were included. Hypertension was present in 25 patients (43%). Arteriolosclerosis, defined as fibrous endarteritis, was present in 35 out of 58 patients (60%) and in all of the controls. No hyalinosis or hyperplastic proliferative arteriolosclerosis was observed in the patients or controls. Only age was an independent factor associated with the presence of cutaneous arteriolosclerosis (p &x#3c; 0.0001). CONCLUSION: Cutaneous arteriolosclerosis is significantly and independently associated with age. Thus, skin biopsy seems not to be necessary for the diagnosis of HLU but only for a differential diagnosis.

Lower-limb Ulcers in Systemic Sclerosis: A Multicentre Retrospective Case-control Study.

Lower-limb ulcers in systemic sclerosis patients are rarely reported. The aim of this study was to describe the main causes and outcomes of lower-limb ulcers in systemic sclerosis patients and to assess factors associated with ischaemic causes (arterial disease and/or microvascular impairment). A retrospective, multicentre, case-control study was conducted in 2013 and 2014, including 45 systemic sclerosis patients presenting lower-limb ulcers between 2008 and 2013. The estimated prevalence of lower-limb ulcers among systemic sclerosis patients was 12.8%. Ulcers were related to venous insufficiency in 22 cases (49%), ischaemic causes in 21 (47%) and other causes in 2 (4%). Complete healing was observed in 60% of cases in a mean time of 10.3 months; 59% relapsed during a mean follow-up of 22 months. Ischaemic lower-limb ulcer outcomes were poor, with a 28.6% amputation rate. Logistic-regression multivariate analyses between ischaemic lower-limb ulcer cases and matched systemic sclerosis-controls identified past or concomitant digital ulcer and cutaneous sclerosis of the feet as independent risk factors associated with ischaemic lower-limb ulcers.
