Maintenance treatment of pemphigus with rituximab in real life: A single-center study of 50 patients.

BACKGROUND: Following the RITUX 3 therapeutic trial, the French national diagnosis and care protocol (NDCP) for the treatment of pemphigus was updated in 2018. The updated protocol recommends initial treatment with rituximab (RTX) followed by maintenance therapy at 12 and 18 months, and potentially at 6 months where there are risk factors for early relapse. We evaluated these recommendations regarding the management of our own patients. PATIENTS AND METHODS: Our single-center retrospective study included all patients with pemphigus diagnosed between 01/2015 and 10/2020 and receiving at least one initial infusion of RTX. We collected the following data: type of pemphigus, severity, levels of anti-desmoglein 1 and 3 antibodies at diagnosis and between 2 and 6 months after initial RTX, presence or absence of maintenance therapy and modalities, time to first relapse and duration of associated systemic corticosteroid therapy ≥5 mg/day. Maintenance treatment modalities were as follows: no maintenance treatment, maintenance "on demand" (MT1) i.e. not performed at the rate imposed by the NDCP, and maintenance "according to NDCP" (MT2). RESULTS: Fifty patients were included (women 54%, median age 58 years, pemphigus vulgaris 68%, moderate to severe 68%). Initial RTX was combined with systemic corticosteroid therapy at 0.5 to 1 mg/kg in 74% of cases. Twenty-seven patients (54%) received no maintenance therapy, 13 were on an MT1 regimen (26%), and 10 were on an MT2 regimen (20%). Median follow-up was 42 months. At the last follow-up, 39 patients (78%) were in complete remission. A total of 25 patients (50%) relapsed: 18/27 (67%) patients without maintenance, 5/13 (38%) with MT1, and 2/10 (20%) with MT2 (p = 0.026). The probability of relapse over time was significantly lower in patients receiving maintenance therapy compared to those who receiving none (p = 0.022). The median time to relapse was 15 months in patients without maintenance, and 30 and 28 in those with maintenance (p = 0.27). The median duration of systemic corticosteroid therapy ≥ 5 mg/day in the no-maintenance group was 10 months, compared to 7 and 9 months respectively in MT1 and MT2 (p = 0.91). CONCLUSION: Our study confirms the value of RTX maintenance therapy in pemphigus in real life.

A Pragmatic Randomized Trial Comparing Surgical Clipping and Endovascular Treatment of Unruptured Intracranial Aneurysms.

BACKGROUND AND PURPOSE: Surgical clipping and endovascular treatment are commonly used in patients with unruptured intracranial aneurysms. We compared the safety and efficacy of the 2 treatments in a randomized trial. MATERIALS AND METHODS: Clipping or endovascular treatments were randomly allocated to patients with one or more 3- to 25-mm unruptured intracranial aneurysms judged treatable both ways by participating physicians. The study hypothesized that clipping would decrease the incidence of treatment failure from 13% to 4%, a composite primary outcome defined as failure of aneurysm occlusion, intracranial hemorrhage during follow-up, or residual aneurysms at 1 year, as adjudicated by a core lab. Safety outcomes included new neurologic deficits following treatment, hospitalization of >5 days, and overall morbidity and mortality (mRS > 2) at 1 year. There was no blinding. RESULTS: Two hundred ninety-one patients were enrolled from 2010 to 2020 in 7 centers. The 1-year primary outcome, ascertainable in 290/291 (99%) patients, was reached in 13/142 (9%; 95% CI, 5%-15%) patients allocated to surgery and in 28/148 (19%; 95% CI, 13%-26%) patients allocated to endovascular treatments (relative risk: 2.07; 95% CI, 1.12-3.83; P = .021). Morbidity and mortality (mRS >2) at 1 year occurred in 3/143 and 3/148 (2%; 95% CI, 1%-6%) patients allocated to surgery and endovascular treatments, respectively. Neurologic deficits (32/143, 22%; 95% CI, 16%-30% versus 19/148, 12%; 95% CI, 8%-19%; relative risk: 1.74; 95% CI, 1.04-2.92; P = .04) and hospitalizations beyond 5 days (69/143, 48%; 95% CI, 40%-56% versus 12/148, 8%; 95% CI, 5%-14%; relative risk: 0.18; 95% CI, 0.11-0.31; P < .001) were more frequent after surgery. CONCLUSIONS: Surgical clipping is more effective than endovascular treatment of unruptured intracranial aneurysms in terms of the frequency of the primary outcome of treatment failure. Results were mainly driven by angiographic results at 1 year.

Stent-Assisted Coiling in the Treatment of Unruptured Intracranial Aneurysms: A Randomized Clinical Trial.

BACKGROUND AND PURPOSE: Stent-assisted coiling may improve angiographic results of endovascular treatment of unruptured intracranial aneurysms compared with coiling alone, but this has never been shown in a randomized trial. MATERIALS AND METHODS: The Stenting in the Treatment of Aneurysm Trial was an investigator-led, parallel, randomized (1:1) trial conducted in 4 university hospitals. Patients with intracranial aneurysms at risk of recurrence, defined as large aneurysms (≥10 mm), postcoiling recurrent aneurysms, or small aneurysms with a wide neck (≥4 mm), were randomly allocated to stent-assisted coiling or coiling alone. The composite primary efficacy outcome was "treatment failure," defined as initial failure to treat the aneurysm; aneurysm rupture or retreatment during follow-up; death or dependency (mRS > 2); or an angiographic residual aneurysm adjudicated by an independent core laboratory at 12 months. The primary hypothesis (revised for slow accrual) was that stent-assisted coiling would decrease treatment failures from 33% to 15%, requiring 200 patients. Primary analyses were intent to treat. RESULTS: Of 205 patients recruited between 2011 and 2021, ninety-four were allocated to stent-assisted coiling and 111 to coiling alone. The primary outcome, ascertainable in 203 patients, was reached in 28/93 patients allocated to stent-assisted coiling (30.1%; 95% CI, 21.2%-40.6%) compared with 30/110 (27.3%; 95% CI, 19.4%-36.7%) allocated to coiling alone (relative risk = 1.10; 95% CI, 0.7-1.7; P = .66). Poor clinical outcomes (mRS >2) occurred in 8/94 patients allocated to stent-assisted coiling (8.5%; 95% CI, 4.0%-16.6%) compared with 6/111 (5.4%; 95% CI, 2.2%-11.9%) allocated to coiling alone (relative risk = 1.6; 95% CI, 0.6%-4.4%; P = .38). CONCLUSIONS: The STAT trial did not show stent-assisted coiling to be superior to coiling alone for wide-neck, large, or recurrent unruptured aneurysms.

Surgical or Endovascular Treatment of MCA Aneurysms: An Agreement Study.

BACKGROUND AND PURPOSE: MCA aneurysms are still commonly clipped surgically despite the recent development of a number of endovascular tools and techniques. We measured clinical uncertainty by studying the reliability of decisions made for patients with middle cerebral artery (MCA) aneurysms. MATERIALS AND METHODS: A portfolio of 60 MCA aneurysms was presented to surgical and endovascular specialists who were asked whether they considered surgery or endovascular treatment to be an option, whether they would consider recruitment of the patient in a randomized trial, and whether they would provide their final management recommendation. Agreement was studied using κ statistics. Intrarater reliability was assessed with the same, permuted portfolio of cases of MCA aneurysm sent to the same specialists 1 month later. RESULTS: Surgical management was the preferred option for neurosurgeons (n = 844/1320; [64%] responses/22 raters), while endovascular treatment was more commonly chosen by interventional neuroradiologists (1149/1500 [76.6%] responses/25 raters). Interrater agreement was only "slight" for all cases and all judges (κ = 0.094; 95% CI, 0.068-0.130). Agreement was no better within specialties or with more experience. On delayed requestioning, 11 of 35 raters (31%) disagreed with themselves on at least 20% of cases. Surgical management and endovascular treatment were always judged to be a treatment option, for all patients. Trial participation was offered to patients 65% of the time. CONCLUSIONS: Individual clinicians did not agree regarding the best management of patients with MCA aneurysms. A randomized trial comparing endovascular with surgical management of patients with MCA aneurysms is in order.

Successful Reperfusion is Associated with Favorable Functional Outcome despite Vessel Perforation during Thrombectomy: A Case Series and Systematic Review.

BACKGROUND: Arterial perforation is a potentially serious complication during endovascular thrombectomy. PURPOSE: Our aim was to describe interventional approaches after arterial perforation during endovascular thrombectomy and to determine whether reperfusion remains associated with favorable outcome despite this complication. DATA SOURCES: Data from consecutive patients with acute stroke undergoing endovascular thrombectomy were retrospectively collected between 2015 to 2020 from a single-center cohort, and a systematic review was performed using PubMed, EMBASE, and Ovid MEDLINE up to June 2020. STUDY SELECTION: Articles reporting functional outcome after arterial perforation during endovascular thrombectomy were selected. DATA ANALYSIS: Functional outcomes of patients achieving successful reperfusion (TICI 2b/3) were compared with outcomes of those with unsuccessful reperfusion in our single-center cohort. We then summarized the literature review to describe interventional approaches and outcomes after arterial perforation during endovascular thrombectomy. DATA SYNTHESIS: In our single-center cohort, 1419 patients underwent endovascular thrombectomy, among whom 32 (2.3%) had vessel perforation and were included in the analysis. The most common hemostatic strategy was watchful waiting (71% of cases). Patients with successful reperfusion had a higher proportion of favorable 90-day mRS scores (60% versus 12.5%; P = .006) and a lower mortality rate (13.3% versus 56.3%, P = .01) than patients without successful reperfusion. Thirteen articles were included in the systematic review. Successful reperfusion also appeared to be associated with better outcomes. LIMITATIONS: Given the low number of published reports, we performed only a descriptive analysis. CONCLUSIONS: Arterial perforation during endovascular thrombectomy is rare but is associated with high mortality rates and poor outcome. However, successful reperfusion remains correlated with favorable outcome in these patients.

Flow Diversion in the Treatment of Intracranial Aneurysms: A Pragmatic Randomized Care Trial.

BACKGROUND AND PURPOSE: Flow diversion is a recent endovascular treatment for intracranial aneurysms. We compared the safety and efficacy of flow diversion with the alternative standard management options. MATERIALS AND METHODS: A parallel group, prerandomized, controlled, open-label pragmatic trial was conducted in 3 Canadian centers. The trial included all patients considered for flow diversion. A Web-based platform 1:1 randomly allocated patients to flow diversion or 1 of 4 alternative standard management options (coiling with/without stent placement, parent vessel occlusion, surgical clipping, or observation) as prespecified by clinical judgment. Patients ineligible for alternative standard management options were treated with flow diversion in a registry. The primary safety outcome was death or dependency (mRS > 2) at 3 months. The composite primary efficacy outcome included the core lab-determined angiographic presence of a residual aneurysm, aneurysm rupture, progressive mass effect during follow-up, or death or dependency (mRS > 2) at 3-12 months. RESULTS: Between May 2011 and November 2020, three hundred twenty-three patients were recruited: Two hundred seventy-eight patients (86%) had treatment randomly allocated (139 to flow diversion and 139 to alternative standard management options), and 45 (14%) received flow diversion in the registry. Patients in the randomized trial frequently had unruptured (83%), large (52% ≥10 mm) carotid (64%) aneurysms. Death or dependency at 3 months occurred in 16/138 patients who underwent flow diversion and 12/137 patients receiving alternative standard management options (relative risk, 1.33; 95% CI, 0.65-2.69; P = .439). A poor primary efficacy outcome was found in 30.9% (43/139) with flow diversion and 45.6% (62/136) of patients receiving alternative standard management options, with an absolute risk difference of 14.7% (95% CI, 3.3%-26.0%; relative risk, 0.68; 95% CI, 0.50-0.92; P = .014). CONCLUSIONS: For patients with mostly unruptured, large, anterior circulation (carotid) aneurysms, flow diversion was more effective than the alternative standard management option in terms of angiographic outcome.

Erythema multiforme associated with anti-plakin antibodies: a multicentric retrospective case series.

BACKGROUND: Erythema multiforme (EM) is a muco-cutaneous inflammatory disease mainly triggered by herpes simplex virus (HSV) recurrences. Association of EM and circulating auto-antibodies against plakins (anti-PLK-Abs [EM-PLK+]) has been reported. However, little is known about this subset of EM. OBJECTIVES: We aimed to describe the clinical and immunological features and response to treatment of EM-PLK+. METHODS: We conducted a retrospective multicentric study of EM-PLK+ selected from the database of the immunological laboratory of Bichat hospital, Paris, France, from January 2009 to December 2020. Anti-PLK-Abs were detected in ≥1 immunological tests: immunofluorescence assay, immunoblotting and/or ELISA. Patients with alternative diagnoses were excluded. RESULTS: We included 29 patients (16 women, median age 25 [range 2-58] years). EM-PLK+ were mostly major (EM with ≥2 mucosal involvements; n = 24, 83%) and relapsing (≥2 flares; n = 23, 79%). Cutaneous lesions were target (n = 13, 54%) and target-like lesions (n = 9, 38%) with usual topography (acral, n = 19, 79%; limbs, n = 21, 88%). Mucosal lesions affected the mouth (n = 27, 96%) and genitalia (n = 19, 68%), with a median of 2 [range 0-5] mucous membranes. EM-PLK+ were suspected as certain or possible postherpetic (EM-HSV) in 19 cases (65.5%); no triggering factors were detected in 9 (31%) patients. Desmoplakin-I/II Abs were the most frequent anti-PLK-Abs (n = 20, 69%); envoplakin and periplakin Abs were detected in 11 and 9 cases. Relapsing EM-PLK+ (n = 23) were still active (≥1 flare within 6 months) in 13 (57%) patients despite immunosuppressive therapy (n = 8, 62%). Antiviral drugs were ineffective in preventing relapse in 15/16 (94%) EM-HSV. CONCLUSION: The rationale for anti-PLK-Ab detection in EM is not elucidated. More systematic research of anti-PLK-Abs is warranted to better understand whether this association reflects humoral immune activity in a subset of EM or is fortuitous, related to an epitope spreading process. However, EM-PLK+ seems to be associated with major and relapsing subtypes, and difficult-to-treat cases.

Psoriasis-related treatment exposure and hospitalization or in-hospital mortality due to COVID-19 during the first and second wave of the pandemic: cohort study of 1 326 312 patients in France.

BACKGROUND: Data on treatment exposures for psoriasis and poor COVID-19 outcomes are limited. OBJECTIVES: To assess the risk of hospitalization or in-hospital mortality due to COVID-19 by treatment exposure in patients with psoriasis. METHODS: All adults with psoriasis registered in the French national health-insurance (Système National des Données de Santé, SNDS) database between 2008 and 2019 were eligible. Two study periods were considered: 15 February to 30 June 2020 and 1 October 2020 to 31 January 2021, the first and second waves of the COVID-19 pandemic in France, respectively. Patients were classified according to their baseline treatment: biologics, nonbiologics, topicals or no treatment. The primary endpoint was hospitalization for COVID-19 using Cox models with inverse probability of treatment weighting. The secondary endpoint was in-hospital mortality due to COVID-19. RESULTS: We identified 1 326 312 patients with psoriasis (mean age 59 years; males, 48%). During the first study period, 3871 patients were hospitalized for COVID-19 and 759 (20%) died; during the second period 3603 were hospitalized for COVID-19 and 686 (19%) died. In the propensity score-weighted Cox models, risk of hospitalization for COVID-19 was associated with exposure to topicals or nonbiologics [hazard ratio (95% confidence interval): 1·11 (1·04-1·20) and 1·27 (1·09-1·48), respectively] during the first period, and with all exposure types, during the second period. None of the exposure types was associated with in-hospital mortality due to COVID-19. CONCLUSIONS: Systemic treatments for psoriasis (including biologics) were not associated with increased risk of in-hospital mortality due to COVID-19. These results support maintaining systemic treatment for psoriasis during the pandemic.

Noninvasive Angiographic Results of Clipped or Coiled Intracranial Aneurysms: An Inter- and Intraobserver Reliability Study.

BACKGROUND AND PURPOSE: Noninvasive angiography is commonly used to assess the outcome of surgical or endovascular treatment of intracranial aneurysms in clinical series or randomized trials. We sought to assess whether a standardized 3-grade classification system could be reliably used to compare the CTA and MRA results of both treatments. MATERIALS AND METHODS: An electronic portfolio composed of CTAs of 30 clipped and MRAs of 30 coiled aneurysms was independently evaluated by 24 raters of diverse experience and training backgrounds. Twenty raters performed a second evaluation 1 month later. Raters were asked which angiographic grade and management decision (retreatment; close or long-term follow-up) would be most appropriate for each case. Agreement was analyzed using the Krippendorff α (αK) statistic, and the relationship between angiographic grade and clinical management choice, using the Fisher exact and Cramer V tests. RESULTS: Interrater agreement was substantial (αK = 0.63; 95% CI, 0.55-0.70); results were slightly better for MRA results of coiling (αK = 0.69; 95% CI, 0.56-0.76) than for CTA results of clipping (αK = 0.58; 95% CI, 0.44-0.69). Intrarater agreement was substantial to almost perfect. Interrater agreement regarding clinical management was moderate for both clipped (αK = 0.49; 95% CI, 0.32-0.61) and coiled subgroups (αK = 0.47; 95% CI, 0.34-0.54). The choice of clinical management was strongly associated with the size of the residuum (mean Cramer V = 0.77 [SD, 0.14]), but complete occlusions (grade 1) were followed more closely after coiling than after clipping (P = .01). CONCLUSIONS: A standardized 3-grade scale was found to be a reliable and clinically meaningful tool to compare the results of clipping and coiling of aneurysms using CTA or MRA.

Reliability of the Diagnosis of Cerebral Vasospasm Using Catheter Cerebral Angiography: A Systematic Review and Inter- and Intraobserver Study.

BACKGROUND AND PURPOSE: Conventional angiography is the benchmark examination to diagnose cerebral vasospasm, but there is limited evidence regarding its reliability. Our goals were the following: 1) to systematically review the literature on the reliability of the diagnosis of cerebral vasospasm using conventional angiography, and 2) to perform an agreement study among clinicians who perform endovascular treatment. MATERIALS AND METHODS: Articles reporting a classification system on the degree of cerebral vasospasm on conventional angiography were systematically searched, and agreement studies were identified. We assembled a portfolio of 221 cases of patients with subarachnoid hemorrhage and asked 17 raters with different backgrounds (radiology, neurosurgery, or neurology) and experience (junior ≤10 and senior >10 years) to independently evaluate cerebral vasospasm in 7 vessel segments using a 3-point scale and to evaluate, for each case, whether findings would justify endovascular treatment. Nine raters took part in the intraobserver reliability study. RESULTS: The systematic review showed a very heterogeneous literature, with 140 studies using 60 different nomenclatures and 21 different thresholds to define cerebral vasospasm, and 5 interobserver studies reporting a wide range of reliability (κ = 0.14-0.87). In our study, only senior raters reached substantial agreement (κ ≥ 0.6) on vasospasm of the supraclinoid ICA, M1, and basilar segments and only when assessments were dichotomized (presence or absence of ≥50% narrowing). Agreement on whether to proceed with endovascular management of vasospasm was only fair (κ ≤ 0.4). CONCLUSIONS: Research on cerebral vasospasm would benefit from standardization of definitions and thresholds. Dichotomized decisions by experienced readers are required for the reliable angiographic diagnosis of cerebral vasospasm.

Epidemiologic study in a real-world analysis of patients with treatment for psoriasis in the French national health insurance database.

BACKGROUND: Psoriasis is one of the most frequent chronic inflammatory dermatoses in the world. Data on the prevalence of psoriasis in adults differ depending on the study. OBJECTIVE: To estimate the prevalence of patients with treatment for psoriasis in France and to identify and characterize patients receiving systemic treatments. METHODS: This was a French, nationwide cohort study based on health administrative data from the French national health insurance scheme linked to the national hospital discharge database (SNDS-PMSI). All adults with psoriasis registered in the SNDS between 1 January 2008 and 31 December 2016 were eligible for inclusion. All patients with a new prescription for a systemic treatment for psoriasis were included. RESULTS: A total of 874 549 patients were identified as having psoriasis (mean ± SD age 53.8 ± 17 years; 52.4% males); 112 969 (13%) had filled at least one prescription for a systemic medication used to treat psoriasis. The prevalence of patients with treatment for psoriasis was estimated at 1.3%. Overall, 73 168 and 16 545 were new users of conventional systemic treatments and biologics, respectively. The most frequent comorbidities associated with psoriasis were hypertension, dyslipidaemia, diabetes and chronic obstructive pulmonary disease. CONCLUSION: The prevalence of psoriasis we found was lower than in other studies. It was probably underestimated because we identified only patients with treatment for psoriasis. Our results concerning comorbidities associated with psoriasis patients requiring systemic treatment were similar to those from other published studies using other data sources, highlighting our ability to catch moderate-to-severe psoriasis. This study highlights the usefulness and reliability of the use of insurance databases in studies, because they allow for a better application to the general population.

Exophthalmos following mechanical thrombectomy for anterior circulation stroke: A retrospective study and review of literature.

BACKGROUND: Anecdotal cases of exophthalmos after acute mechanical thrombectomy have been described. We sought to estimate the incidence in a large cohort of patients with acute anterior circulation stroke treated with mechanical thrombectomy. Secondarily, we aimed to evaluate the underlying mechanism and to differentiate it on imaging from other pathology with similar clinical orbital features. METHODS: Between November 2016 and November 2018, we performed a retrospective single-center study of 250 patients who underwent anterior circulation mechanical thrombectomy. Development of exophthalmos was independently evaluated by two readers on preprocedure and 24-h postprocedure non-contrast cerebral CT. RESULTS: In the mechanical thrombectomy cohort, six individuals (2.4%) developed interval ipsilateral exophthalmos at 24 h. Of these, at least two patients developed clinical symptoms. There was almost perfect agreement between assessments of the two readers (Cohen's kappa = 0.907 (95% confidence interval: 0.726, 1.000)). In two patients, there was delayed ophthalmic artery filling on digital subtraction angiography. None of the patients had features of a direct carotid-cavernous fistula. CONCLUSIONS: Exophthalmos is not uncommon after mechanical thrombectomy (2.4%). The underlying mechanism is difficult to confirm, but it is most likely due to orbital ischemia from hypoperfusion or distal emboli.

Reliability of CT Angiography in Cerebral Vasospasm: A Systematic Review of the Literature and an Inter- and Intraobserver Study.

BACKGROUND AND PURPOSE: Computed tomography angiography offers a non-invasive alternative to DSA for the assessment of cerebral vasospasm following subarachnoid hemorrhage but there is limited evidence regarding its reliability. Our aim was to perform a systematic review (Part I) and to assess (Part II) the inter- and intraobserver reliability of CTA in the diagnosis of cerebral vasospasm. MATERIALS AND METHODS: In Part I, articles reporting the reliability of CTA up to May 2018 were systematically searched and evaluated. In Part II, 11 raters independently graded 17 arterial segments in each of 50 patients with SAH for the presence of vasospasm using a 4-category scale. Raters were additionally asked to judge the presence of any moderate/severe vasospasm (≥ 50% narrowing) and whether findings would justify augmentation of medical treatment or conventional angiography ± balloon angioplasty. Four raters took part in the intraobserver reliability study. RESULTS: In Part I, the systematic review revealed few studies with heterogeneous vasospasm definitions. In Part II, we found interrater reliability to be moderate at best (κ ≤ 0.6), even when results were stratified according to specialty and experience. Intrarater reliability was substantial (κ > 0.6) in 3/4 readers. In the per arterial segment analysis, substantial agreement was reached only for the middle cerebral arteries, and only when senior raters' judgments were dichotomized (presence or absence of ≥50% narrowing). Agreement on the medical or angiographic management of vasospasm based on CTA alone was less than substantial (κ ≤ 0.6). CONCLUSIONS: The diagnosis of vasospasm using CTA alone was not sufficiently repeatable among observers to support its general use to guide decisions in the clinical management of patients with SAH.

Does Increasing Packing Density Using Larger Caliber Coils Improve Angiographic Results of Embolization of Intracranial Aneurysms at 1 Year: A Randomized Trial.

BACKGROUND AND PURPOSE: The impact of increased aneurysm packing density on angiographic outcomes has not been studied in a randomized trial. We sought to determine the potential for larger caliber coils to achieve higher packing densities and to improve the angiographic results of embolization of intracranial aneurysms at 1 year. MATERIALS AND METHODS: Does Embolization with Larger Coils Lead to Better Treatment of Aneurysms (DELTA) was an investigator-initiated multicenter prospective, parallel, randomized, controlled clinical trial. Patients had 4- to 12-mm unruptured aneurysms. Treatment allocation to either 15- (experimental) or 10-caliber coils (control group) was randomized 1:1 using a Web-based platform. The primary efficacy outcome was a major recurrence or a residual aneurysm at follow-up angiography at 12 ± 2 months adjudicated by an independent core lab blinded to the treatment allocation. Secondary outcomes included indices of treatment success and standard safety outcomes. Recruitment of 564 patients was judged necessary to show a decrease in poor outcomes from 33% to 20% with 15-caliber coils. RESULTS: Funding was interrupted and the trial was stopped after 210 patients were recruited between November 2013 and June 2017. On an intent-to-treat analysis, the primary outcome was reached in 37 patients allocated to 15-caliber coils and 36 patients allocated to 10-caliber coils (OR = 0.931; 95% CI, 0.528-1.644; P = .885). Safety and other clinical outcomes were similar. The 15-caliber coil group had a higher mean packing density (37.0% versus 26.9%, P = .0001). Packing density had no effect on the primary outcome when adjusted for initial angiographic results (OR = 1.001; 95% CI, 0.981-1.022; P = .879). CONCLUSIONS: Coiling of aneurysms randomized to 15-caliber coils achieved higher packing densities compared with 10-caliber coils, but this had no impact on the angiographic outcomes at 1 year, which were primarily driven by aneurysm size and initial angiographic results.

Persistence of apremilast in moderate-to-severe psoriasis: a real-world analysis of 14 147 apremilast- and methotrexate-naive patients in the French National Health Insurance database.

BACKGROUND: Real-world data on the persistence of apremilast vs. methotrexate are inconclusive. OBJECTIVES: To assess and compare the long-term persistence of apremilast and methotrexate in a large cohort of patients with psoriasis. METHODS: All adult patients with psoriasis registered in the French national health insurance database ('Système National des Données de Santé') between 2009 and 2017 were eligible for inclusion. The study population comprised apremilast- and methotrexate-naive patients, defined as those with a first prescription of apremilast or methotrexate. Levels of persistence were compared using a Cox model with propensity-score matching that included potential confounders (notably age, sex, psoriatic arthritis, comorbidities and previous exposure to topical and systemic treatments). RESULTS: In this nationwide population-based cohort, 14 147 adult patients with psoriasis (mean age 52·3 years, 55·2% male) were found to be naive to both apremilast and methotrexate. After propensity-score matching, two subgroups of 4805 patients with similar baseline characteristics were included, of whom 3207 apremilast-treated patients and 2736 methotrexate-treated patients discontinued their treatment. Kaplan-Meier survival propensity-score analyses revealed a discontinuation rate of 69% for apremilast and 59% for methotrexate in the first year of treatment. Apremilast-treated patients had a higher risk of discontinuation than methotrexate-treated patients when considering the study population as a whole (hazard ratio 1·28, 95% confidence interval 1·23-1·34) or in a propensity-score-matched analysis (hazard ratio 1·34, 95% confidence interval 1·27-1·41; P < 0·001). CONCLUSIONS: Our real-world data suggest that in the first year of treatment, the discontinuation rate was significantly higher for apremilast-treated patients than for methotrexate-treated patients, regardless of the previous therapeutic lines received. What's already known about this topic? Psoriasis is a common chronic, relapse-remitting, inflammatory skin disease associated with severe psychosocial impact. Apremilast, a phosphodiesterase 4 inhibitor, is one of the most recently commercialized psoriasis drugs. Little is known about the long-term clinical effectiveness of apremilast. What does this study add? The discontinuation rate at 1 year for apremilast was 69%, compared with 58% for methotrexate, in a nationwide population-based cohort including 14 147 nonselected adult patients with psoriasis. Patients in the apremilast cohort had a higher risk of discontinuation than patients in the methotrexate cohort using propensity-score matching, including potentially relevant individual risk factors such as age, sex, comorbidities and psoriatic arthritis, and regardless of the previous therapeutic lines received. In daily practice, physicians should take these results into account when choosing between methotrexate and apremilast as a first-line systemic therapy.

A randomized trial of endovascular versus surgical management of ruptured intracranial aneurysms: Interim results from ISAT2.

BACKGROUND AND PURPOSE: Appropriate management of ruptured intracranial aneurysm (RIA) in patients eligible for surgical clipping but under-represented in or excluded from previous randomized trials remains undetermined. METHODS: The International Subarachnoid Aneurysm Trial-2 (ISAT-2) is a randomized care trial comparing surgical versus endovascular treatment (EVT) of RIA. All patients considered for surgical clipping but eligible for endovascular treatment can be included. The primary endpoint is death or dependency on modified Rankin score (mRS>2) at 1 year. Secondary endpoints are 1 year angiographic results and length of hospital stay. RESULTS: An interim analysis was performed after 103 patients were treated from November 2012 to July 2017 in 4 active centers. Fifty-two of the 55 patients allocated to surgery were treated by clipping, and 45 of the 48 allocated to EVT were treated by coiling, with 3 crossovers in each arm. The main endpoint (1 year mRS>2), available for 76 patients, was reached in 16/42 patients allocated to clipping (38%; 95%CI: 25%-53%), and 10/34 patients allocated to coiling (29%; 17%-46%). One year imaging results were available in 54 patients: complete aneurysm occlusion was found in 23/27 patients allocated to clipping (85%; 67%-94%), and 18/27 patients allocated to coiling (67%; 47%-81%). Hospital stay exceeding 20 days was more frequent in surgery (26/55 [47%; 34%-60%]) than EVT (9/48 [19%; 10%-31%]). CONCLUSION: Ruptured aneurysm patients for whom surgical clipping may still be best can be managed in a randomized care trial, which is feasible in some centers. More participating centers are needed.
