Abstract Background Pediatric lupus nephritis (pLN) is one of the most refractory secondary kidney diseases in childhood. The treat-to-target (T2T) strategy has become the standard treatment for systemic lupus erythematosus (SLE). This study reviewed clinical features, overall remission status, and factors affecting prognosis, to guide pLN management according to T2T strategy. Methods This single-center retrospective study studied 220 children diagnosed with LN from January 2012 to December 2018, with > 6-month follow-up data on 173 and complete data on 137 patients. Primary outcome was treatment failure (deterioration or no response) at the latest follow-up. Results The most common pLN manifestation was proteinuria (81.36%). Females presented more often with rash (P<0.001) and alopecia (P=0.026) than males. Class IV LN (33.33%) was the most common grade on kidney biopsy. Median follow-up was 27.20 months (IQR, 15.78–44.45 months). One-, 3-, and 5-year cumulative overall survival rates were 93.5%, 87.8%, and 86.5%, respectively. The 5-year cumulative kidney survival rate was 97.1%. Regarding initial therapy, efficacy of corticosteroids combined with immunosuppressive agents was significantly better than corticosteroids alone (P=0.010). Factors with P<0.05 in univariate analysis, including hypoalbuminemia, higher SCr at diagnosis, lower eGFR at diagnosis, anti-dsDNA positivity, heavy proteinuria, hypertension, nervous-system involvement, treatment non-compliance, and SLEDAI-2K score, were used for logistic regression analysis. Logistic regression analysis showed hypertension (OR=0.845, P=0.011), nervous-system involvement (OR=4.240, P=0.005), treatment non-compliance (OR=6.433, P=0.001), and lower estimated glomerular filtration rate at diagnosis (OR=1.020, P=0.021) affected prognosis. At end of follow-up, 34.31% achieved varying levels of remission, and 8.76% were in low disease activity state (LDAS). Conclusions pLN usually presented with proteinuria, and class IV LN was the dominant pathology. Hypertension, nervous-system involvement, treatment non-compliance, and lower eGFR at diagnosis were independent risk factors for poor prognosis of kidney outcomes. Compared with renal remission rate and cumulative overall survival rate, the proportion of targets achieved was not ideal, suggesting T2T strategy should be used to guide pLN management.

Background:Nervous system involvement is considered to be rare in systemic sclerosis (SSc). Its prevalence is highly variable in SSc cohort studies and its prognosis is not well established.Objectives:To determine the frequency, clinical characteristics, associations, and outcomes of different types of peripheral nervous system (PNS) and central nervous system (CNS) disease in a cohort of systemic sclerosis patients.Methods:We have carried out a retrospective observational study by systematically analyzing the medical records of patients diagnosed with SSc in Toulouse University Hospital and Ducuing Hospital, south west France. We included patients who met the following inclusion criteria: being over 18 years of age on diagnosis, meeting the ACR /EULAR 2013 classification criteria, being diagnosed after 01/01/1966 and before 31/12/2018, at least 12 months of follow-up. Patients were followed until 31/12/2019. Nervous system involvement associated with SSc was included when there was involvement on or after diagnosis and after exclusion of all other causes. Only symptomatic clinical involvement was included. Ischemic or hemorrhagic strokes were excluded. We calculated the incidence of CNS and/or PNS disease during the follow-up period per 1,000 person-years. Kaplan-Meier curves were plotted to determine the cumulative incidence of nervous system disease. We evaluated associated factors of CNS and/or PNS disease using multivariable Cox regression.Results:Of 447 SSc patients, 79.8% were female, 68 (15%) were diffuse cutaneous SSc, 342 (77%) were limited cutaneous SSc and 37 (8%) were sine scleroderma SSc. The mean ± SD age at diagnosis was 52.9 ± 14.3 years.During the study period, 82 (18%) patients experienced a PNS disease, 29 (6%) a CNS disease. The incidence was 28 per 1,000 patient-years of any nervous system disease, with 22 per 1,000 patient-years and 6 per 1,000 patient-years of PNS disease and CNS disease, respectively. The most frequent were carpal tunnel syndrome (63%) and polyneuropathies (12%) for PNS disease, and headache (45%) and seizures (10%) for CNS disease.Three significant independent associated factors with PNS disease occurrence were identified using multivariable Cox regression: BMI>23.1kg/m2(HR = 1.06 [1.01-1.12]), joint involvement (HR = 2.7 [1.3-5.5]), and an alteration in the left ventricular ejection fraction (HR = 3.8 [1.4-10.3]).Four significant independent associated factors with CNS disease occurrence were identified: age > 54 years (HR = 2.5 [1.1-6.0]), positive anti-PmScl testing (HR = 6.4 [1.5-28.2]), Caucasian origin (HR = 0.2 [0.1-0.5]) and hemoglobin < 12g/dl (HR = 0.2 [0.04-0.8]).Nervous system disease occurrence did not appear to have a negative impact on the survival of SSc patients (log-rank p=0.56).Conclusion:This study shows that specific nervous system disease in SSc is not uncommon and does not appear to increase mortality, but it could have an impact on functional prognosis and needs to be monitored.Disclosure of Interest:None declared

Objective To assess the impact of rural-urban residence on children with obstructive sleep-disordered breathing (SDB) who were candidates for tonsillectomy with or without adenoidectomy (TA). Study Design Retrospective cohort study. Setting Tertiary children’s hospital. Methods A cohort of otherwise healthy children aged 2 to 18 years with a diagnosis of obstructive SDB between April 2016 and December 2018 who were recommended TA were included. Rural-urban designation was defined by ZIP code approximation of rural-urban commuting area codes. The main outcome was association of rurality with time to TA and loss to follow-up using Cox and logistic regression analyses. Results In total, 213 patients were included (mean age 6 ± 2.9 years, 117 [55%] male, 69 [32%] rural dwelling). Rural-dwelling children were more often insured by Medicaid than private insurance ( P < .001) and had a median driving distance of 74.8 vs 16.8 miles ( P < .001) compared to urban-dwelling patients. The majority (94.9%) eventually underwent recommended TA once evaluated by an otolaryngologist. Multivariable logistic regression analysis did not reveal any significant predictors for loss to follow-up in receiving TA. Cox regression analysis that adjusted for age, sex, insurance, and race showed that rural-dwelling patients had a 30% reduction in receipt of TA over time as compared to urban-dwelling patients (hazard ratio, 0.7; 95% CI, 0.50-0.99). Conclusion Rural-dwelling patients experienced longer wait times and driving distance to TA. This study suggests that rurality should be considered a potential barrier to surgical intervention and highlights the need to further investigate geographic access as an important determinant of care in pediatric SDB.

Background:Several previous observational studies have suggested that patients with anti-Ro/SSA antibody-positive rheumatoid arthritis (RA) may respond poorly to treatment, including tumor necrosis factor inhibitors1. However, its influence on methotrexate (MTX) treatment, which is the anchor drug of treat-to-target strategy in RA treatment, remains unclear.Objectives:We compared the clinical response to MTX in both anti-Ro/SSA antibody-positive and -negative patients with MTX-naiive RA and investigated the reasons for the difference in response.Methods:We recruited 210 consecutive patients with RA who were newly started on MTX in this retrospective cohort study. The effect of the presence of anti-Ro/SSA antibodies on achieving low disease activity (LDA) of DAS28-CRP at six months after initiating MTX was investigated by using logistic regression analysis. CDAI, SDAI, concomitant using DMARDs and painkillers, patient’s and evaluator’s VAS, tender joint counts, and swollen joint counts at six months were also compared between the anti-Ro/SSA-positive patients and -negative patients. Missing data were imputed by using multiple imputations before multivariate analysis.Results:32 anti-Ro/SSA antibody-positive patients and 178 anti-Ro/SSA antibody-negative patients were included. The rate of achieving DAS28-LDA at six months was significantly lower in the anti-Ro/SSA antibody-positive patients than those in the anti-Ro/SSA antibody-negative patients (56.2% versus 75.8%, P=0.03). in the logistic regression analysis, the presence of anti-Ro/SSA antibodies was an independent negative predictor for achieving DAS-28-LDA at six months (OR:0.431, 95%CI: 0.190-0.978, P=0.044) (Table1). Anti-Ro/SSA antibody-positive patients had significantly higher patient’s VAS at six months (median [IQR]: 22 [15-41] vs 19 [5-30], P=0.038), and prescribed NSAIDs (37.5% vs 18.0%, P=0.018). CDAI and SDAI after six months were not significantly different between the group.Conclusion:The presence of anti-Ro/SSA antibodies might be one of the predictive factors for the insufficient response to treat to target strategy in RA treatment. Residual pain was suspected as one of the mechanisms contributing to the lesser clinical response of MTX in anti-Ro antibody-positive RA.References:[1]Ran Matsudaira wt al.

Abstract Background and Aims Anemia is a well-know complication of Chronic Kidney Disease (CKD) and it seems to contribute for deterioration of kidney function. Experimental data suggest that anemia produces hypoxia of tubular cells which leads to tubulointerstitial damage resulting on CKD progression. Other mechanism described is that red blood cells have antioxidant properties that prevent the damage of tubulointerstitial cells and glomerulosclerosis from oxidative stress. There aren’t many observational studies that evaluated the association between anemia and progression of CKD. Therefore, our aim was to evaluate the association of anemia and CKD progression and its association outcomes in an outpatient ND-CKD population. Method We conduct a retrospective, patient-level, cohort analysis of all adult ND-CKD patients evaluated in an outpatient nephrology clinic over a 6 years period. The follow up time was at least 12 months. Anemia was defined according to the WHO definition (hemoglobin [hb] &lt; 13.0 g/dL in men and 12.0 g/dL in women). Progression of CKD was defined by one of the following criteria: decline in eGFR (CKD-EPI) superior to 5 ml/min/1.73 m2/year; duplication of serum creatinine or the need renal replacement therapy. Demographics and clinical data were also accessed. Results Out of 3008 patients referred to the nephrology clinic, 49.9% had anemia (mean age 71.9±15.9 years; 50.4% male; 92% white; mean follow-up time of 2.3±1.2 years). The mean Hb was 11.8 ±1.9 g/dL. Important cardiovascular comorbidities in patients with anemia were arterial hypertension (86.7%), obesity (65.5%), Diabetes Mellitus (DM) (52%) and dyslipidemia (46%). In univariate analysis, mortality was associated with anemia (36.9 vs 13.0%, p&lt;0.001), obesity (30.1 vs 21.8%, p&lt;0.001) and DM (30.1 vs 21.1%, p&lt;0.001). Of the patients with anemia, 738 met the criteria for CKD progression. In univariate analysis, CKD progression was associated with anemia (49.6 vs 43.9%, p=0.002), male gender (49.5 vs 43.6% p= 0.001); DM (49.6 vs 44.8 % p=0.009) and hypertension (47.9 vs 42.3% p=0.0018). In multivariate logistic regression analysis, anemia emerged was an independent predictor of CKD progression (OR 1.435, CI 95% 1.21-1.71, p&lt;0,001). Comparing hb values intervals (hb ≤10g/dl; hb10-12 g/dL; hb ≥12 g/dL), in the multivariate logistic regression analysis, hb ≤10g/dl was not associated with CKD progression and hb value between 10-12 g/dL was associated (OR 1,486, CI 95% 1.23-1.80, p&lt;0,001), when compared with the group with hb ≥12g/dL. In multivariate logistic regression analysis, the independent predictors of mortality were: older age (OR per 1 year increase: 1.048, 95% CI 95% 1.04-1.06, p&lt;0.001); arterial hypertension (OR 0.699 CI 95% 0.51-0.96, p=0.0029); obesity (OR 0.741, CI 95% 0.60-0.91, p=0.004) and hb value (OR per 1 g/dL decrease: 1.301, CI 95% 1.23-1.38, p&lt;0.001). Cardiovascular events were correlated with Hb levels between 10-12 g/dL (univariate analysis: OR 2.021, CI 95% 1.27-3.22, P=0.003), but not with the group with hb≤10 g/dL (univariate analysis: OR 1.837, CI 95% 0.96-3.51, P=0.066), having the group with hb ≥12g/dL was reference. Anemia was strongly associated with hospitalizations (multivariate logistic regression analysis: OR per 1 g/dL of Hb decrease: 1.256 CI 95% 1.12-1.32 p&lt;0.001), and this strong association was also observed on the groups with hb hb≤10 g/dL (multivariate logistic regression analysis: OR 3.591 CI 95% 32.67-4.84 p&lt;0.001) and between 10-12 g/dL (multivariate logistic regression analysis: OR 1.678 CI 95% 1.40-2.02, p&lt;0.001) Conclusion Our study suggests that anemia, at first consultation, increases the risk for rapid CKD progression and global mortality. This study could guide us on the development of futures studies in order to prove if anemia correction can slow the progression of CKD.

Background: Decompressive hemicraniectomy (DH) is a level IA therapy for malignant middle cerebral artery (MCA) infarction. However, randomized trials were performed in high income countries with better access to post-stroke care and rehabilitation services. We aimed to assess long term functional outcome and the associated prognostic factors of patients undergoing DH in Brazil. Methods: From January 2013 and July 2018, all patients undergoing DH for malignant MCA infarction in a single comprehensive stroke center were retrospectively identified. Outcomes were the modified Rankin Scale (mRS) (dichotomized as ≤ 4 vs. > 4) and mortality at follow-up. The mRS at follow-up was collected prospectively by telephone using a validated structured interview. Logistic regression analysis was performed to assess independent predictors of outcome. Results: Eighty patients who underwent DH for malignant MCA infarction were identified. Age ranged from 16 to 78 years (median 48 years, IQR 42 - 54,7 years), 46 (57.6%) were males and median time from stroke onset to hemicraniectomy was 30.75 hours (IQR 17.8-46.0). Hospital discharge mRS ≤ 3 and ≤ 4 was observed in 5 (6.2%) and 74 (92,5%) patients respectively. Follow-up information was available for 65 (81.2%) patients. At follow-up (raging from 1.1 to 5.6 years), mRS ≤ 4 was observed in 23 (35.3%) patients. In binary logistic regression analysis, age (OR 1.09, 95% CI 1.02 - 1.17, p=0.01), and right MCA infarction (OR 16.70, 95% CI 1.8-152.30, p=0.01) were independently associated with a worse functional outcome at follow-up. Admission NIHSS (OR 1.0 ,95% CI 0.8-1.3, p=0.45), IV rt-PA (OR 0.5, 95% CI 0.08-3.00, p=0.46) or time of hemicraniectomy (OR 1.00, 95% CI 1.00 - 1.00, p=0.94) were not associated with functional outcome at follow-up. Mortality was 26% (N=21) at hospital discharge and 46% (N=30) at follow-up. Conclusion: The large effect size of DH for malignant MCA infarction is significantly diminished in the population of patients treated under the less than ideal conditions typically found in the public healthcare system of a developing country. Poor access to post-stroke care and rehabilitation services might be possible reasons for the results observed.

Background: In acute ischemic stroke (AIS) patients due to intracranial atherosclerosis-related occlusions (ICAS-O), despite successful reperfusion with mechanical thrombectomy (MT), unexpected early reocclusion sometimes occurs and worsens clinical outcome. We investigated prevalence, outcomes, and predictors of early reocclusion within 48 hours of MT in AIS due to ICAS-O. Methods: In 557 consecutive AIS patients who underwent MT from January, 2016 to March, 2019 in two stroke centers, 71 patients due to ICAS-O were retrospectively evaluated. We divided them into two groups: patients with early reocclusion and those without. Clinical and angiographical findings and outcomes were compared between the 2 groups. Multivariable logistic regression analysis was used to investigate predictors of early reocclusion after MT. Results: Of 71 patients (aged 72 ± 10 years; 23 women; median NIHSS score, 15), early reocclusion was observed in 11 (15%). The first procedure for recanalization was stent retriever in 25 patients (35%), Penumbra system in 25 patients (35%), and balloon angioplasty in 21 patients (30%). Of these, 63 patients (88%) received rescue therapy (balloon angioplasty, 50; intracranial stenting, 13). In the early reocclusion group, more number of intraprocedural reocclusion (median [IQR], 3 [2-3] vs. 1 [0-1], p < 0.001), a higher rate of remaining stenosis on the final angiography (67.6 ± 5.9% vs 57.3 ± 15.9%, p = 0.044), and a higher rate of procedure-related adverse events (27% vs 5%, p = 0.043) were observed compared to the other group. On logistic regression analysis, a total number of intraprocedural reocclusion was independently associated with early reocclusion (odds ratio, 31.4; 95% confidence interval, 2.6-375.2). Early reocclusion was related to a low rate of favorable outcome at 90 days (modified Rankin Scale ≤ 2, 9% vs 54%, p = 0.007). Conclusions: In AIS patients due to ICAS-O, early reocclusion within 48 hours was not rare and associated with unfavorable outcome. Patients with repeated intraprocedural reocclusion are at high risk for early reocclusion; they might need follow-up angiographical assessment and intensive antithrombotic treatment.

Intramedullary Spinal Cord

OBJECTIVELaminoplasty has been used in recent years as an alternative approach to laminectomy for preventing spinal deformity after resection of intramedullary spinal cord tumors (IMSCTs). However, controversies exist with regard to its real role in maintaining postoperative spinal alignment. The purpose of this study was to examine the incidence of progressive spinal deformity in patients who underwent laminoplasty for resection of IMSCT and identify risk factors for progressive spinal deformity.METHODSData from IMSCT patients who had undergone laminoplasty at Beijing Tsinghua Changgung Hospital between January 2014 and December 2016 were retrospectively reviewed. Univariate tests and multivariate logistic regression analysis were used to assess the statistical relationship between postoperative spinal deformity and radiographic, clinical, and surgical variables.RESULTSOne hundred five patients (mean age 37.0 ± 14.5 years) met the criteria for inclusion in the study. Gross-total resection (> 95%) was obtained in 79 cases (75.2%). Twenty-seven (25.7%) of the 105 patients were found to have spinal deformity preoperatively, and 10 (9.5%) new cases of postoperative progressive deformity were detected. The mean duration of follow-up was 27.6 months (SD 14.5 months, median 26.3 months, range 6.2–40.7 months). At last follow-up, the median functional scores of the patients who did develop progressive spinal deformity were worse than those of the patients who did not (modified McCormick Scale: 3 vs 2, and p = 0.04). In the univariate analysis, age (p = 0.01), preoperative spinal deformity (p < 0.01), extent of tumor involvement (p < 0.01), extent of abnormal tumor signal (p = 0.02), and extent of laminoplasty (p < 0.01) were identified as factors associated with postoperative progressive spinal deformity. However, in subsequent multivariate logistic regression analysis, only age ≤ 25 years and preoperative spinal deformity emerged as independent risk factors (p < 0.05), increasing the odds of postoperative progressive deformity by 4.1- and 12.4-fold, respectively (p < 0.05).CONCLUSIONSProgressive spinal deformity was identified in 25.7% patients who had undergone laminoplasty for IMSCT resection and was related to decreased functional status. Younger age (≤ 25 years) and preoperative spinal deformity increased the risk of postoperative progressive spinal deformity. The risk of postoperative deformity warrants serious reconsideration of providing concurrent fusion during IMSCT resection or close follow-up after laminoplasty.

OBJECTIVEPrimary Meige syndrome is characterized by blepharospasm and orofacial–cervical dystonia. Deep brain stimulation (DBS) is recognized as an effective therapy for patients with this condition, but previous studies have focused on clinical effects. This study explored the predictors of clinical outcome in patients with Meige syndrome who underwent DBS.METHODSTwenty patients who underwent DBS targeting the bilateral subthalamic nucleus (STN) or globus pallidus internus (GPi) at the Chinese People’s Liberation Army General Hospital from August 2013 to February 2018 were enrolled in the study. Their clinical outcomes were evaluated using the Burke–Fahn–Marsden Dystonia Rating Scale at baseline and at the follow-up visits; patients were accordingly divided into a good-outcome group and a poor-outcome group. Putative influential factors, such as age and course of disease, were examined separately, and the factors that reached statistical significance were subjected to logistic regression analysis to identify predictors of clinical outcomes.RESULTSFour factors showed significant differences between the good- and poor-outcome groups: 1) the DBS target (STN vs GPi); 2) whether symptoms first appeared at multiple sites or at a single site; 3) the sub-item scores of the mouth at baseline; and 4) the follow-up period (p < 0.05). Binary logistic regression analysis revealed that initial involvement of multiple sites and the mouth score were the only significant predictors of clinical outcome.CONCLUSIONSThe severity of the disease in the initial stage and presurgical period was the only independent predictive factor of the clinical outcomes of DBS for the treatment of patients with Meige syndrome.

Abstract Late recovery of left ventricular function in patients with non-severe ischemic mitral regurgitation and multivessel disease qualified to cardiosurgery treatment. Purpose In patients (pts) after myocardial infarction (MI) with chronic left ventricle (LV) dysfunction, the presence and degree of ischemic mitral regurgitation (IMR) are predominantly related to LV remodelling and mitral valvular deformation. The aim of this study was to compare functional recovery (LVFR) as well as reverse remodelling of the left ventricle (LVRR) in pts with non-severe IMR qualified for cardiosurgical treatment - coronary artery bypass grafting alone (CABGa) or CABG with mitral repair (CABGmr in the 12-month follow-up. Materials and methods A total of 100 pts (mean age 64,4 ± 7,9 years) after MI, eligible for CABG, were included in a prospective study. Echo and clinical assessment were performed before and 12-months after surgery. Pts were referred for CABG a(gr.1; n = 74) or CABGmr (gr.2; n = 26) based on clinical assessment, 2D echo at rest and exercise and myocardial viability assessment (low dose dobutamine - dbx). Effective regurgitation orifice area (EROA) was used for quantitative IMR assessment. An increase in EF≥ 5% (ΔEF) from baseline value was considered as LVFR. A decrease in LV end-systolic volume &gt; 15% from baseline value was considered as LVRR. Multivariable logistic regression analysis was used to identify the strongest factors of lack of LVFR and LVRR. Results An LVFR was observed, at late control, in 35 (49%) of pts in the CABGa group and in 11 (48%) of pts in CABGmr group (p = 0,948). LVRR was observed in 41 (56%) of pts in the CABGa group and in 16 (70%) of pts in CABGmr group 12 months follow-up (p = 0,5). In pts with LVFR, there was a lower incidence of at least moderate IMR at follow-up (ΔEF dbx≥5% vs ΔEFdbx &lt; 5%:11% vs 30% pts; p = 0,05). Multivariable logistic regression analysis revealed that in both CABGa and CABGmr group only preoperative age and EF changes during stress echo remained the independent predictors of the lack of LVFR in 12 months follow-up (table 1). Conclusions 1. LVFR and LVRR were reported in most of the pts in both analyzed groups. 2. Preoperative assessment of changes EF during dbx (ΔEFdbx)can be used to identify pts with IMR at increased risk of lack of improvement in LV function and risk of residual IMRin 12-month f-up after surgery.
