Early progression in follicular lymphoma in the absence of histological transformation or high-risk Follicular Lymphoma International Prognostic Index still has a favourable outcome. Br J Haematol 2023; 200:306-314. [PMID: 36261137 DOI: 10.1111/bjh.18522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 10/03/2022] [Accepted: 10/07/2022] [Indexed: 01/21/2023]
Abstract
Although follicular lymphoma (FL) patients relapsing within 24 months after first-line treatment (POD24) have a poor prognosis, some cases show notable survival after first relapse (SF1R). We aimed to characterize the POD24 FL population and to identify the main prognostic factors at progression. We selected 162 POD24 patients (80F; median age at first relapse 59 years) from a cohort of 1067 grades 1-3a FL-treated patients. The remaining 905 patients treated with first-line immunochemotherapy and diagnosed during the same period were used to compare outcomes in terms of survival. After a median follow-up of 11.0 years, 96 patients died (10y-SF1R of 40%). Age over 60 years (p < 0.001), high lactate dehydrogenase (LDH) (p < 0.001), haemoglobin (Hb) less than 120 g/L (p < 0.001), advanced stage (p < 0.001), high-risk Follicular Lymphoma International Prognostic Index (FLIPI) (p < 0.001), histological transformation (HT) (p < 0.001) and reaching less than complete response (CR) after salvage therapy (p < 0.001), predicted poor SF1R at relapse. In multivariate analysis only high-risk FLIPI and HT maintained prognostic significance for SF1R. POD24 patients not transformed and with low/intermediate FLIPI at relapse behaved better than the remaining cases. POD24 patients showed an excess mortality of 38% compared to the general population. Although outcome of POD24 FL patients is poor, a considerable group of them (low/intermediate FLIPI and not transformed at first relapse) behave better.

Comparative clinical prognosis of massive and non-massive pulmonary embolism: A registry-based cohort study. J Thromb Haemost 2021; 19:408-416. [PMID: 33119949 DOI: 10.1111/jth.15146] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 09/29/2020] [Accepted: 10/21/2020] [Indexed: 01/16/2023]
Abstract
AIMS Little is known about the prognosis of patients with massive pulmonary embolism (PE) and its risk of recurrent venous thromboembolism (VTE) compared with non-massive PE, which may inform clinical decisions. Our aim was to compare the risk of recurrent VTE, bleeding, and mortality after massive and non-massive PE during anticoagulation and after its discontinuation. METHODS AND RESULTS We included all participants in the RIETE registry who suffered a symptomatic, objectively confirmed segmental or more central PE. Massive PE was defined by a systolic hypotension at clinical presentation (<90 mm Hg). We compared the risks of recurrent VTE, major bleeding, and mortality using time-to-event multivariable competing risk modeling. There were 3.5% of massive PE among 38 996 patients with PE. During the anticoagulation period, massive PE was associated with a greater risk of major bleeding (subhazard ratio [sHR] 1.72, 95% confidence interval [CI] 1.28-2.32), but not of recurrent VTE (sHR 1.15, 95% CI 0.75-1.74) than non-massive PE. An increased risk of mortality was only observed in the first month after PE. After discontinuation of anticoagulation, among 11 579 patients, massive PE and non-massive PE had similar risks of mortality, bleeding, and recurrent VTE (sHR 0.85, 95% CI 0.51-1.40), but with different case fatality of recurrent PE (11.1% versus 2.4%, P = .03) and possibly different risk of recurrent fatal PE (sHR 3.65, 95% CI 0.82-16.24). CONCLUSION In this large prospective registry, the baseline hemodynamic status of the incident PE did not influence the risk of recurrent VTE, during and after the anticoagulation periods, but was possibly associated with recurrent PE of greater severity.

Relapse rate and renal prognosis in ANCA-associated vasculitis according to long-term ANCA patterns. Clin Exp Immunol 2020; 203:209-218. [PMID: 33020895 DOI: 10.1111/cei.13530] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 09/15/2020] [Accepted: 09/28/2020] [Indexed: 01/30/2023] Open
Abstract
Long-term observation of patients with ANCA-associated vasculitis (AAV) allows the identification of different longitudinal patterns of ANCA levels during follow-up. This study aimed to characterize these patterns and to determine their prognostic significance. All ANCA determinations performed in two university hospitals during a 2-year period were retrospectively reviewed. Patients were included in the analysis if they had high titers of anti-myeloperoxidase (anti-MPO) or anti-proteinase 3 (anti-PR3) antibodies at least once, ≥ 5 serial ANCA determinations and AAV diagnosed by biopsy or American College of Rheumatology (ACR) classification criteria. Patients' time-course ANCA patterns were classified as monophasic, remitting, recurrent or persistent. Associations between ANCA patterns and prognostic variables (relapse rate and renal outcome) were analysed by univariate and multivariate statistics. A total of 99 patients [55 with microscopic polyangiitis (MPA), 36 with granulomatosis with polyangiitis (GPA) and eight with eosinophilic granulomatosis with polyangiitis (EGPA)] were included. Median follow-up was 9 years. Among patients diagnosed with MPA or GPA, recurrent or persistent ANCA patterns were associated with a higher risk of clinical relapse [hazard ratio (HR) = 3·7, 95% confidence interval (CI) = 1·5-9·1 and HR = 2·9, 95% CI = 1·1-8·0, respectively], independently of clinical diagnosis or ANCA specificity. In patients with anti-MPO antibodies, the recurrent ANCA pattern was associated with worsening renal function [odds ratio (OR) = 5·7, 95% CI = 1·2-26·0]. Recurrent or persistent ANCA patterns are associated with a higher risk of clinical relapse. A recurrent ANCA pattern was associated with worsening renal function in anti-MPO-associated vasculitis.

Abstract
Background:Anti-PM/Scl antibodies are associated to systemic sclerosis (SSc) but are not specific to SSc. The true prevalence of anti-PM/Scl antibodies in SSc is unknown, ranging from 2.5% to 12.5%. An association between anti-PM/Scl antibodies with muscular involvement, pulmonary fibrosis, calcinosis, and a relatively benign prognosis have been described.Objectives:To compare the clinical manifestations and prognosis of SSc patients according the presence of anti-PM/Scl antibodies in the cohort of RESCLE (Spanish Scleroderma Registry).Methods:From the Spanish Scleroderma Study Group database, we selected patients in whom anti-PM/Scl antibodies had been tested. We compared demographic features, clinical manifestations, laboratory characteristics, and survival data between patients according the anti-PM/Scl antibodies status.Results:72 out of 947 (7%) patients tested positive for anti-PM/Scl antibodies. As presenting SSc manifestations, patients with anti-PM/Scl antibodies had higher prevalence of puffy fingers (11% versus 2%; p=0.002) and arthralgias (11% versus 4%; p=0.03), and lower prevalence of Raynaud’s phenomenon (65% versus 82%, p=0.002). Regarding cumulative manifestations, myositis (51% versus 15%; p<0.001), arthritis (43% versus 22%; p=0.001), and interstitial lung disease (ILD) (60% versus 45%, p=0.014) were more prevalent in patients with anti-PM/Scl antibodies. In fact, those patients with anti-Pm/Scl antibodies presented with FVC (77.4% ± 23.1% versus 85.8% ± 23,1%; p=0.006) and more severe ILD defined as FVC <70% (41% versus 24%; p=0.004). Death rate was similar in patients with and without PM/Scl antibodies (18% versus 17%; p=0.871).We did not find differences in terms of death rate nor in the causes of death (SSc and non-SSc related) according to the anti-PM/Scl antibodies profile.The 5- and 10-years survival rates of patients with anti-PM/Scl antibodies were 91% and 82% respectively, without differences with those without these antibodies (93% and 85%, respectively).Conclusion:In Spanish SSc patients, the presence of anti-PM/Scl antibodies confer a distinctive clinical profile. However, anti-PM/Scl antibodies do not play a role in the prognosis of these patients.References:[1]Stochmal A, Czuwara J, Trojanowska M, Rudnicka L.

Abstract
Background:Scleroderma renal crisis (SRC) prevalence is decreasing. However, no Systemic Sclerosis (SSc) patient’s registry has evaluated that decrease over time. No treatment have been able to prevent SRC development.Objectives:Primary objective: to identify SRC prevalence in 2 periods in the RESCLE(Registro deESCLErodermia) registry. Secondary objective: to idenfy which features could justify that change on SRC prevalence.Methods:Up to December 2018, 1937 SSc patients were included by 31 referral centers in RESCLE registry. SRC prevalence and incidence in diagnosed patients before and after 2003 was determined. Clinical characteristics of diagnosed patients in each period of time were analysed to identify differences between them.Results:Out of 1937 SSc, 43 (2.2%) developed SRC. Prevalence of SRC before and after 2003 was 3.5% and 1.08%. SRC Incidence: Graphic 1. Significant differences between Pre-2003 vs. Post-2003 SSc cohorts were found in univariate analysis: Table 1 and 2.Table. 1.Univariate analysisPre-2003(%)Post-2003(%)Demographic datalcSSc6359dcSSc2815ssSSc6.414Early SSc1.13.3Very early SSc1.99.6Age at SSc dx49.1(±15.2)y55.0(±15.6)yTime from SSc dx to SRC1.1(0.2-4.3)y0.6(0.1-1.5)yACR/EULAR 2013 criteria9986ComorbiditiesSmoked2037Arterial hypertension3529Diagnostic proceduresPAPs >40mmHg by Echocardiography3825Not-sclerodermal pattern at VCS8.919Lupus anticoagulant124.8Prognostic featuresOverall mortality2911ILD-related death101.6Conclusion:SRC Prevalence and Incidence has decreased. Prevalence is three-fold in diagnosed SSc cohort pre-2003 than in post-2003. The post-2003 cohort showed lesser prevalence of dcSSc subtype, earlier SSc diagnosis, less organic involvement and more intensive treatment than pre-2003 cohort. All these findings could explain the decline in the SRC prevalence.Figure:Table 2.Univariate analysisPre-2003 (%)Post-2003 (%)Clinical dataSkin sclerosis (as 1stsymptom)7.24.1Digital ulcers4931Telangiectasia6652Acroosteolysis124.6Calcinosis2914Joint contractures2813ILD4937Cardiac conduction alteration2027Left diastolic dysfunction4132Peripheral neuropathy136.1Sicca syndrome3724Treatment featuresCalcium channel blockers2340Specific vasodilators2.114Prostaglandin0.993.4Angiotensin system inhibitors5.116Corticosteroids1120Immunosuppressant315y: years old; lcSSc: limited cutaneous SSc; dcSSc: diffuse cutaneous SSc; ssSSc: sine scleroderma SSc; ILD: Interstitial lung disease; PAPs: systolic Pulmonary Arterial Pressure; VCS: Video-capillaroscopy; dx: diagnosisDisclosure of Interests:Xavier Pla Salas: None declared, Carles Tolosa Consultant of: Actelion pharmaceuticals, GSK, MSD., Alfredo Guillén del Castillo: None declared, María Esther Sánchez García: None declared, Jorge Sánchez-Redondo: None declared, Eduardo L.

Abstract
Background:Pulmonary arterial hypertension (PAH) and interstitial lung disease (ILD) are the major life-threatening complications in systemic sclerosis (SSc). Data on the impact of PAH and/or ILD in SSc patients (pts) are limited by their low prevalence.Objectives:To assess differences in demographic/clinical characteristics of SSc pts according to presence of PAH and how these are affected by ILD. The impact on characteristics and survival of PAH + ILD was also assessed.Methods:We compared data on SSc pts without PAH from the Spanish registry of patients with SSc (RESCLE) (SSc pts) and SSc pts with PAH from the Spanish registry of pts with PAH (REHAP) (SSc-PAH pts). Only data common in both registries were analyzed. Sub analyses were performed according to the presence/absence of ILD. Transplant-free survival from diagnosis of PAH was estimated using the Kaplan-Meier method.Results:1,579 pts with SSc (RESCLE) and 364 pts with SSc-PAH (REHAP) were analyzed. Compared to SSc pts, SSc-PAH pts had worse functional status (NYHA FC III/IV: 70.6% vs. 8.2% in SSc pts) and pulmonary function (lower mean forced vital capacity [FVC, 81.2±20.6% vs. 93.6±20] and diffusing capacity for carbon monoxide [DLCO, 45.3±17.7% vs. 79.0±36.6%]). More patients had FVC/DLCO ≥1.4 (77.8% vs. 34.8%), tricuspid regurgitation (91.4% vs. 46.1%) or pericardial effusion (30.0% vs. 5.1%). Mean systolic pulmonary artery pressure (sPAP) was higher (70.0±21.3 vs. 27.5±9.1 mmHg) (all respectively; P<0.001 for all). Prevalence of ILD on high-resolution computerized tomography was similar (44.9% [n=92] vs. 41.8% [n=422] in SSc pts; P=0.408). These differences were also found when splitting both cohorts according to the presence / absence of ILD. Compared to SSc-PAH pts without ILD (n=128), pts with PAH + ILD (n=92) had worse functional status (NYHA FC III: 69.6% vs. 55.5% in SSc-PAH pts without ILD; P=0.036), lower mean FVC (70.9±21.9 vs. 86.2±18.6) and lower DLCO (39.4 ±17.0 vs. 49.1±17.9) both P<0.001. Five-year survival rate was 35% in SSc-PAH pts with ILD vs. 45% in SSc-PAH without ILD (P=0.444 [figure 1]).Conclusion:PAH has a profound impact on functional status, pulmonary function and right ventricle function of SSc patients, independently of presence of ILD. Despite the deleterious effect of functional status and pulmonary function, in pts with SSc and PAH, presence of concomitant ILD has no impact on 5-year survival.Disclosure of Interests:Alfredo Guillén-del-Castillo Consultant of: Actelion pharmaceuticals, GSK, MSD., Manuel López-Meseguer Consultant of: Actelion pharmaceuticals, GSK, MSD., Carles Tolosa Consultant of: Actelion pharmaceuticals, GSK, MSD., Antonio Romás Broto Consultant of: Actelion pharmaceuticals, GSK, MSD., Dolores Colunga Argüelles Consultant of: Actelion pharmaceuticals, GSK, MSD., Isabel Blanco Consultant of: Actelion pharmaceuticals, GSK, MSD., Antoni Castro Consultant of: Actelion pharmaceuticals, GSK, MSD., Raquel López Reyes Consultant of: Actelion pharmaceuticals, GSK, MSD., Adela Marín Ballvé: None declared, Isabel Otero González Consultant of: Actelion pharmaceuticals, GSK, MSD., Vicent Fonollosa-Pla Consultant of: Actelion pharmaceuticals, GSK, MSD., Ernest Sala LLinas Consultant of: Actelion pharmaceuticals, GSK, MSD., Pilar Escribano Subías Consultant of: Actelion pharmaceuticals, GSK, MSD., Carmen Pilar Simeón-Aznar Consultant of: Actelion pharmaceuticals, GSK, MSD.

Abstract
BACKGROUND Patients with venous thromboembolism (VTE) secondary to transient risk factors may develop VTE recurrences after discontinuing anticoagulation. Identifying at-risk patients could help to guide the duration of therapy. METHODS We used the RIETE database to assess the prognostic value of d-dimer testing after discontinuing anticoagulation to identify patients at increased risk for recurrences. Transient risk factors were classified as major (postoperative) or minor (pregnancy, oestrogen use, immobilization or recent travel). RESULTS In December 2018, 1655 VTE patients with transient risk factors (major 460, minor 1195) underwent d-dimer measurements after discontinuing anticoagulation. Amongst patients with major risk factors, the recurrence rate was 5.74 (95% CI: 3.19-9.57) events per 100 patient-years in those with raised d-dimer levels and 2.68 (95% CI: 1.45-4.56) in those with normal levels. Amongst patients with minor risk factors, the rates were 7.79 (95% CI: 5.71-10.4) and 3.34 (95% CI: 2.39-4.53), respectively. Patients with major risk factors and raised d-dimer levels (n = 171) had a nonsignificantly higher rate of recurrences (hazard ratio [HR]: 2.14; 95% CI: 0.96-4.79) than those with normal levels. Patients with minor risk factors and raised d-dimer levels (n = 382) had a higher rate of recurrences (HR: 2.34; 95% CI: 1.51-3.63) than those with normal levels. On multivariate analysis, raised d-dimers (HR: 1.74; 95% CI: 1.09-2.77) were associated with an increased risk for recurrences in patients with minor risk factors, not in those with major risk factors. CONCLUSIONS Patients with raised d-dimer levels after discontinuing anticoagulant therapy for VTE provoked by a minor transient risk factor were at an increased risk for recurrences.

Abstract
A rare variant (BAFF-var) of the tumor necrosis factor superfamily 13b (TNFSF13B) gene has been recently associated with multiple sclerosis (MS) and systemic lupus erythematosus (SLE). The aim of this study was to investigate the association between TNFSF13B BAFF-var and susceptibility to rheumatoid arthritis (RA) and replicate that association in SLE. 6,218 RA patients, 2,575 SLE patients and 4,403 healthy controls from three different countries were included in the study. TNFSF13B BAFF-var was genotyped using TaqMan allelic discrimination assay. PLINK software was used for statistical analyses. TNFSF13B BAFF-var was significantly associated with RA (p = 0.015, OR = 1.21, 95% CI = 1.03-1.41) in the Spanish cohort. A trend of association was observed in the Dutch (p = 0.115) and German (p = 0.228) RA cohorts. A meta-analysis of the three RA cohorts included in this study revealed a statistically significant association (p = 0.002, OR = 1.24, 95% CI = 1.10-1.38). In addition, TNFSF13B BAFF-var was significantly associated with SLE in the Spanish (p = 0.001, OR = 1.41, 95% CI = 1.14-1.74) and the German cohorts (p = 0.030, OR = 1.86, 95% CI = 1.05-3.28), with a statistically significant p-value obtained in the meta-analysis (p = 0.0002, OR = 1.46, 95% CI = 1.09-2.32). The results obtained confirm the known association of TNFSF13B BAFF-var with SLE and, for the first time, demonstrate that this variant contributes to susceptibility to RA.

First clinical symptom as a prognostic factor in systemic sclerosis: results of a retrospective nationwide cohort study. Clin Rheumatol 2017; 37:999-1009.

Abstract
The objective of the study is to determine the importance of the mode of onset as prognostic factor in systemic sclerosis (SSc). Data were collected from the Spanish Scleroderma Registry (RESCLE), a nationwide retrospective multicenter database created in 2006. As first symptom, we included Raynaud's phenomenon (RP), cutaneous sclerosis, arthralgia/arthritis, puffy hands, interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), and digestive hypomotility. A total of 1625 patients were recruited. One thousand three hundred forty-two patients (83%) presented with RP as first symptom and 283 patients (17%) did not. Survival from first symptom in those patients with RP mode of onset was higher at any time than those with onset as non-Raynaud's phenomenon: 97 vs. 90% at 5 years, 93 vs. 82% at 10 years, 83 vs. 62% at 20 years, and 71 vs. 50% at 30 years (p < 0.001). In multivariate analysis, factors related to mortality were older age at onset, male gender, dcSSc subset, ILD, PAH, scleroderma renal crisis (SRC), heart involvement, and the mode of onset with non-Raynaud's phenomenon, especially in the form of puffy hands or pulmonary involvement. The mode of onset should be considered an independent prognostic factor in systemic sclerosis and, in particular, patients who initially present with non-Raynaud's phenomenon may be considered of poor prognosis.

Abstract
INTRODUCTION Whether women developing venous thromboembolism (VTE) while using hormonal therapy should be classified as having "unprovoked" or "provoked" VTE is controversial. METHODS We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to compare the rate of symptomatic VTE recurrences after discontinuing anticoagulation in 3 subgroups of women aged ≤50years without cancer, pregnancy or puerperium: (1) those with hormonal therapy and no additional risk factors (hormonal users only); (2) those with unprovoked VTE; and (3) those with additional risk factors, with or without hormonal therapy. RESULTS As of March 2016, 1513 women had been followed-up for at least one month after discontinuing anticoagulation. Of these, 654 (43%) were hormonal users only, 390 (26%) had unprovoked VTE and 469 (31%) had transient risk factors with or without hormonal therapy. After discontinuing anticoagulation, the rate of VTE recurrences in women with hormonal use only (2.44 per 100 patient-years; 95% CI: 1.53-3.69) was significantly lower than in those with unprovoked VTE (6.03; 95% CI: 3.97-8.77) and similar to those with transient risk factors (2.58; 95% CI: 1.50-4.13). Interestingly, the rate of VTE recurrences presenting as pulmonary embolism in women with hormonal use only (0.55 per 100 patient-years; 95% CI: 0.18-1.29) was similar to those with transient risk factors (0.46; 95% CI: 0.09-1.33) and 4-fold lower than in women with unprovoked VTE (2.23; 95% CI: 1.07-4.10). CONCLUSIONS After discontinuing anticoagulation, the rate of VTE recurrences in hormonal users only was significantly lower than in women with unprovoked VTE and similar to the rate in women with additional risk factors.

Predictors of active cancer thromboembolic outcomes. RIETE experience of the Khorana score in cancer-associated thrombosis. Thromb Haemost 2017; 117:1192-1198. [PMID: 28276571 DOI: 10.1160/th16-11-0840] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Accepted: 02/23/2017] [Indexed: 12/14/2022]
Abstract
Even though the Khorana risk score (KRS) has been validated to predict against the development of VTE among patients with cancer, it has a low positive predictive value. It is also unknown whether the score predicts outcomes in patients with cancer with established VTE. We selected a cohort of patients with active cancer from the RIETE (Registro Informatizado Enfermedad TromboEmbolica) registry to assess the prognostic value of the KRS at inception in predicting the likelihood of VTE recurrences, major bleeding and mortality during the course of anticoagulant therapy. We analysed 7948 consecutive patients with cancer-associated VTE. Of these, 2253 (28 %) scored 0 points, 4550 (57 %) 1-2 points and 1145 (14 %) scored ≥3 points. During the course of anticoagulation, amongst patient with low, moderate and high risk KRS, the rate of VTE recurrences was of 6.21 (95 %CI: 4.99-7.63), 11.2 (95 %CI: 9.91-12.7) and 19.4 (95 %CI: 15.4-24.1) events per 100 patient-years; the rate of major bleeding of 5.24 (95 %CI: 4.13-6.56), 10.3 (95 %CI: 9.02-11.7) and 19.4 (95 %CI: 15.4-24.1) bleeds per 100 patient-years and the mortality rate of 25.3 (95 %CI: 22.8-28.0), 58.5 (95 %CI: 55.5-61.7) and 120 (95 %CI: 110-131) deaths per 100 patient-years, respectively. The C-statistic was 0.53 (0.50-0.56) for recurrent VTE, 0.56 (95 %CI: 0.54-0.59) for major bleeding and 0.54 (95 %CI: 0.52-0.56) for death. In conclusion, most VTEs occur in patients with low or moderate risk scores. The KRS did not accurately predict VTE recurrence, major bleeding, or mortality among patients with cancer-associated thrombosis.

The Clinical Course of Venous Thromboembolism May Differ According to Cancer Site. Am J Med 2017; 130:337-347. [PMID: 27884650 DOI: 10.1016/j.amjmed.2016.10.017] [Citation(s) in RCA: 65] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2016] [Revised: 09/21/2016] [Accepted: 10/24/2016] [Indexed: 11/28/2022]
Abstract
BACKGROUND We hypothesized that the clinical course of venous thromboembolism in patients with active cancer may differ according to the specificities of primary tumor site. AIM AND METHODS We used data from RIETE (international registry of patients with venous thromboembolism) to compare the clinical venous thromboembolism-related outcomes during the course of anticoagulation in patients with one of the 4 more frequent cancers (breast, prostate, colorectal, or lung cancer). RESULTS As of September 2014, 3947 cancer patients were recruited, of whom 938 had breast, 629 prostate, 1189 colorectal, and 1191 lung cancer. Overall, 55% had metastatic disease (42%, 36%, 53%, and 72%, respectively). During the course of anticoagulant therapy (mean duration, 139 days), the rate of thromboembolic recurrences was similar to the rate of major bleeding in patients with breast (5.6 [95% confidence interval (CI), 3.8-8.1] vs 4.1 [95% CI, 2.7-5.9] events per 100 patient-years) or colorectal cancer (10 [95% CI, 7.6-13] vs 12 [95% CI, 9.4-15] per 100 patient-years). In contrast, in patients with prostate cancer, the rate of venous thromboembolic recurrences was half the rate of major bleeding (6.9 [95% CI, 4.4-10] vs 13 [95% CI, 9.2-17] events per 100 patient-years), whereas in those with lung cancer, the rate of thromboembolic recurrences was twofold higher than the rate of major bleeding (27 [95% CI, 22-23] vs 11 [95% CI, 8.6-15] per 100 patient-years). CONCLUSIONS Significant differences in the clinical profile of venous thromboembolic-related outcomes were observed according to the site of cancer. These findings suggest the development of cancer-specific anticoagulant strategies as an area for further research.

First month prednisone dose predicts prednisone burden during the following 11 months: an observational study from the RELES cohort. Lupus Sci Med 2016; 3:e000153.

Abstract
Aim To study the influence of prednisone dose during the first month after systemic lupus erythematosus (SLE) diagnosis (prednisone-1) on glucocorticoid burden during the subsequent 11 months (prednisone-2–12). Methods 223 patients from the Registro Español de Lupus Eritematoso Sistémico inception cohort were studied. The cumulative dose of prednisone-1 and prednisone-2–12 were calculated and recoded into a four-level categorical variable: no prednisone, low dose (up to 7.5 mg/day), medium dose (up to 30 mg/day) and high dose (over 30 mg/day). The association between the cumulative prednisone-1 and prednisone-2–12 doses was tested. We analysed whether the four-level prednisone-1 categorical variable was an independent predictor of an average dose >7.5 mg/day of prednisone-2–12. Adjusting variables included age, immunosuppressives, antimalarials, methyl-prednisolone pulses, lupus nephritis and baseline SLE Disease Activity Index (SLEDAI). Results Within the first month, 113 patients (51%) did not receive any prednisone, 24 patients (11%) received average low doses, 46 patients (21%) received medium doses and 40 patients (18%) received high doses. There was a strong association between prednisone-1 and prednisone-2–12 dose categories (p<0.001). The cumulative prednisone-1 dose was directly associated with the cumulative prednisone-2–12 dose (p<0.001). Compared with patients on no prednisone, patients taking medium (adjusted OR 5.27, 95% CI 2.18 to 12.73) or high-dose prednisone-1 (adjusted OR 10.5, 95% CI 3.8 to 29.17) were more likely to receive prednisone-2–12 doses of >7.5 mg/day, while patients receiving low-dose prednisone-1 were not (adjusted OR 1.4, 95% CI 0. 0.38 to 5.2). If the analysis was restricted to the 158 patients with a baseline SLEDAI of ≥6, the model did not change. Conclusion The dose of prednisone during the first month after the diagnosis of SLE is an independent predictor of prednisone burden during the following 11 months.

Abstract
OBJECTIVES During the last years, genome-wide association studies (GWASs) have identified a number of common genetic risk factors for rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). However, the genetic overlap between these two immune-mediated diseases has not been thoroughly examined so far. The aim of the present study was to identify additional risk loci shared between RA and SLE. METHODS We performed a large-scale meta-analysis of GWAS data from RA (3911 cases and 4083 controls) and SLE (2237 cases and 6315 controls). The top-associated polymorphisms in the discovery phase were selected for replication in additional datasets comprising 13 641 RA cases and 31 921 controls and 1957 patients with SLE and 4588 controls. RESULTS The rs9603612 genetic variant, located nearby the COG6 gene, an established susceptibility locus for RA, reached genome-wide significance in the combined analysis including both discovery and replication sets (p value=2.95E-13). In silico expression quantitative trait locus analysis revealed that the associated polymorphism acts as a regulatory variant influencing COG6 expression. Moreover, protein-protein interaction and gene ontology enrichment analyses suggested the existence of overlap with specific biological processes, specially the type I interferon signalling pathway. Finally, genetic correlation and polygenic risk score analyses showed cross-phenotype associations between RA and SLE. CONCLUSIONS In conclusion, we have identified a new risk locus shared between RA and SLE through a meta-analysis including GWAS datasets of both diseases. This study represents the first comprehensive large-scale analysis on the genetic overlap between these two complex disorders.

Abstract
OBJECTIVES This is the first Spanish multicentric inception lupus cohort, formed by SLE patients attending Spanish Internal Medicine Services since January 2009. We aimed to analyse drug therapy during the first year of follow-up according to disease severity. METHODS 223 patients who had at least one year of follow-up were enrolled upon diagnosis of SLE. Therapy with prednisone, pulse methyl-prednisolone, hydroxychloroquine, immunosuppressives and calcium/vitamin D was analysed. RESULTS Prednisone was given to 65% patients, at a mean (SD) daily dose of 11 (10) mg/d. 38% patients received average doses >7.5 mg/d during the first year. Patients with nephritis and with a SLEDAI ≥6 were treated with higher doses of prednisone. 81% of patients were treated with hydroxychloroquine, with higher frequency among those with a SLEDAI ≥6 (88% vs. 68%, p<0.001). The use of immunosuppressive drugs and methyl-prednisolone pulses was higher in patients with a baseline SLEDAI ≥6, however, differences were no longer significant when patients with lupus nephritis were excluded. The use of calcium/vitamin D increased with the dose of prednisone, however, 43% of patients on medium-high doses of prednisone did not take any calcium or vitamin D. CONCLUSIONS This study gives a real-world view of the current therapeutic approach to early lupus in Spain. The generalised use of hydroxychloroquine is well consolidated. There is still a tendency to use prednisone at medium to high doses. Pulse methyl-prednisolone and immunosuppressive drugs were used in more severe cases, but not as steroid sparing agents. Vitamin D use was suboptimal.

Abstract
The outcome of patients with acute venous thromboembolism (VTE) and abnormal platelet count (PlC) at baseline has not been consistently studied. In real-world clinical practice, a number of patients with abnormal PlC receive vitamin K antagonists (VKAs) to treat acute VTE despite their higher risk of bleeding.We used the Registro Informatizado de Enfermedad TromboEmbólica registry database to compare the rate of major bleeding in patients receiving VKA for long-term therapy of acute VTE according to PlC levels at baseline. Patients were categorized as having very low (<100,000/μL), low (100,000-150,000/μL), normal (150,000-300,000/μL), high (300,000-450,000/μL), or very high (>450,000/μL) PlC at baseline.Of 55,369 patients recruited as of January 2015, 37,000 (67%) received long-term therapy with VKA. Of these, 611 patients (1.6%) had very low PlC, 4006 (10.8%) had low PlC, 25,598 (69%) had normal PlC, 5801 (15.6%) had high PlC, and 984 (2.6%) had very high PlC at baseline. During the course of VKA therapy (mean, 192 days), there were no differences in the duration or intensity (as measured by international normalized ratio levels) of treatment between subgroups. The rate of major bleeding was 3.6%, 2.1%, 1.9%, 2.1%, and 3.7%, respectively, and the rate of fatal bleeding was 0.98%, 0.17%, 0.29%, 0.34%, and 0.50%, respectively. Patients with very low or very high PlC levels were more likely to have severe comorbidities.We found a nonlinear "U-shaped" relationship between PlC at baseline and major bleeding during therapy with VKA for VTE. Consistent alteration of PlC values at baseline suggested a greater frailty.

Abstract
Objective CD5 plays a crucial role in autoimmunity and is a well-established genetic risk factor of developing RA. Recently, evidence of positive selection has been provided for the CD5 Pro224-Val471 haplotype in East Asian populations. The aim of the present work was to further analyze the functional relevance of non-synonymous CD5 polymorphisms conforming the ancestral and the newly derived haplotypes (Pro224-Ala471 and Pro224-Val471, respectively) as well as to investigate the potential role of CD5 on the development of SLE and/or SLE nephritis. Methods The CD5 SNPs rs2241002 (C/T; Pro224Leu) and rs2229177 (C/T; Ala471Val) were genotyped using TaqMan allelic discrimination assays in a total of 1,324 controls and 681 SLE patients of Spanish origin. In vitro analysis of CD3-mediated T cell proliferative and cytokine response profiles of healthy volunteers homozygous for the above mentioned CD5 haplotypes were also analyzed. Results T-cell proliferation and cytokine release were significantly increased showing a bias towards to a Th2 profile after CD3 cross-linking of peripheral mononuclear cells from healthy individuals homozygous for the ancestral Pro224-Ala471 (CC) haplotype, compared to the more recently derived Pro224-Val471 (CT). The same allelic combination was statistically associated with Lupus nephritis. Conclusion The ancestral Ala471 CD5 allele confers lymphocyte hyper-responsiveness to TCR/CD3 cross-linking and is associated with nephritis in SLE patients.

Abstract
Peak age at onset of systemic sclerosis (SSc) is between 20 and 50 years, although SSc is also described in both young and elderly patients. We conducted the present study to determine if age at disease onset modulates the clinical characteristics and outcome of SSc patients. The Spanish Scleroderma Study Group recruited 1037 patients with a mean follow-up of 5.2 ± 6.8 years. Based on the mean ± 1 standard deviation (SD) of age at disease onset (45 ± 15 yr) of the whole series, patients were classified into 3 groups: age ≤ 30 years (early onset), age between 31 and 59 years (standard onset), and age ≥ 60 years (late onset). We compared initial and cumulative manifestations, immunologic features, and death rates. The early-onset group included 195 patients; standard-onset group, 651; and late-onset, 191 patients. The early-onset group had a higher prevalence of esophageal involvement (72% in early-onset compared with 67% in standard-onset and 56% in late-onset; p = 0.004), and myositis (11%, 7.2%, and 2.9%, respectively; p = 0.009), but a lower prevalence of centromere antibodies (33%, 46%, and 47%, respectively; p = 0.007). In contrast, late-onset SSc was characterized by a lower prevalence of digital ulcers (54%, 41%, and 34%, respectively; p < 0.001) but higher rates of heart conduction system abnormalities (9%, 13%, and 21%, respectively; p = 0.004). Pulmonary hypertension was found in 25% of elderly patients and in 12% of the youngest patients (p = 0.010). After correction for the population effects of age and sex, standardized mortality ratio was shown to be higher in younger patients. The results of the present study confirm that age at disease onset is associated with differences in clinical presentation and outcome in SSc patients.

Abstract
Chronic obstructive pulmonary disease (COPD) is a moderate risk factor for venous thromboembolism (VTE), but neither the clinical presentation nor the outcome of VTE in COPD patients is well known. The clinical presentation of VTE, namely pulmonary embolism (PE) or deep venous thrombosis (DVT), and the outcome at 3 months (death, recurrent VTE or bleeding) were compared between 2,984 COPD patients and 25,936 non-COPD patients included in the RIETE (Registro Informatizado de la Enfermedad TromboEmbólica) registry. This ongoing international, multi-centre registry includes patients with proven symptomatic PE or DVT. PE was the more frequent VTE presentation in COPD patients (n = 1,761, 59%). PE presentation was more significantly associated with COPD patients than non-COPD patients (OR 1.64, 95% CI 1.49-1.80). During the 3-month follow-up, mortality (10.8% versus 7.6%), minor bleeding (4.5% versus 2.3%) or first VTE recurrences as PE (1.5% versus 1.1%) were significantly higher in COPD patients than in non-COPD patients. PE was the most common cause of death. COPD patients presented more frequently with PE than DVT. It may explain the worse prognosis of COPD patients, with a higher risk of death, bleeding or VTE recurrences as PE compared with non-COPD patients. Further therapeutic options are needed.

Abstract
BACKGROUND The clinical significance of symptomatic isolated distal deep vein thrombosis (DVT) is uncertain. Consequently, this leads to important disparities in its management. OBJECTIVE To examine the clinical history of isolated distal DVT and to compare it with that of proximal DVT. METHODS Using data from the international, prospective, RIETE registry on patients with confirmed symptomatic venous thromboembolism (VTE), we compared the risk factors and 3-month outcome in patients with isolated distal DVT vs. proximal DVT. RESULTS Eleven thousand and eighty-six patients with symptomatic DVT, but without pulmonary embolism, were included between 2001 and 2008; 1921 (17.3%) exhibited isolated distal DVT. Anticoagulant treatment was received by 89.1% (1680/1885) of isolated distal DVT and 91.8% (7911/8613) of proximal DVT patients for the entire follow-up period. Isolated distal DVTs were more associated with transient risk factors (i.e. recent travel, hospitalization, recent surgery), whereas proximal DVTs were more associated with chronic states (i.e. > or =75 years or with active cancer). At 3 months, major bleeding rate was lower in patients with isolated distal DVT (1.0% vs. 2.2%, P < 0.01), whereas VTE recurrence rate was equivalent (2.0% vs. 2.7%, P = 0.07). The mortality rate was lower in patients with isolated distal DVT (2.7% vs. 7.5%; P < 0.001); this was mainly due to a lower rate of non-VTE-related deaths (2.2% vs. 6.3%; P < 0.001). Active cancer was the main predictive factor of death in patients with isolated distal DVT. CONCLUSIONS Proximal and isolated distal DVT patients differ in terms of risk factors and clinical outcomes, suggesting different populations. In the short term, the life expectancy of patients with isolated distal DVT depended chiefly on their cancer status.

Abstract
OBJECTIVE To examine the role of HLA-DRB1 and HLA-DQB1 alleles in the susceptibility to systemic sclerosis (SSc) and its clinical expression in a Spanish population. METHODS One hundred Spanish Caucasian patients with SSc and 130 controls were studied. Molecular HLA-DRB1 and HLA-DQB1 typing was performed by polymerase chain reaction (PCR) sequence-based typing and PCR sequence-specific oligonucleotide. RESULTS HLA-DRB1*11 was associated with genetic susceptibility to SSc, whereas HLA-DRB1*07 (HLA-DRB1*0701) showed a protective effect. A significant increase in the frequency of the DRB1*1104 allele was observed in patients with anti-topoisomerase I autoantibodies (anti-Topo I) while HLA-DRB1*01 and HLA-DQB1*05 alleles were significantly increased in patients with anti-centromere antibodies (ACA). The HLA-DRB1*11 allele was more frequent in patients with pulmonary fibrosis; however, no significant association with any HLA-DRB1 or DQB1 alleles was identified in patients with pulmonary arterial hypertension. CONCLUSION HLA alleles play a role in genetic susceptibility to SSc in Spanish patients. Some alleles are more prevalent in patients with pulmonary fibrosis and in patients with certain SSc-specific autoantibodies (anti-Topo I and ACA).

MATERIALS AND METHODS A retrospective study of TABs conducted between 1989 and 2007 at the 450-bed Hospital Parc Taulí, Sabadell. Demographic data, clinical manifestations, analytical data prior to the biopsy and final diagnoses were recorded, including only those cases in which these data were reflected in the clinical history. RESULTS In this period, 278 TABs were conducted in 181 women (65.1%) and 97 men (mean age 74 years). Seventy-nine (28.4%) were positive (GCA+) and 199 (71.5%) negative (TAB-). The most frequent final diagnoses in the TAB- group were: polymyalgia rheumatica (PMR) (18.6%), giant cell arteritis plus negative TAB (GCA-) (13.6%), tension headache (7.5%), infection (7.5%), other vasculitis (7.5%), and neoplasm (6.0%). The GCA+ group was compared with the TAB- group, the GCA- group and the PMR group. In the multivariate analysis only headache (RR 3.6), jaw claudication (RR 2.9) and abnormal temporal artery on palpation (RR 2.5) revealed statistical differences between the GCA+ and TAB- groups. CONCLUSION One third of the biopsies performed at our centre were positive for GCA. The clinical variables that best predicted a positive TAB in our series were headache, jaw claudication, and abnormal temporal artery on palpation.

Abstract
We hereby describe the satisfactory evolution of rituximab treatment in two patients with Wegener’s granulomatosis (WG). Rituximab was indicated for refractoriness to standard treatment in one case and life-threatening myelotoxicity due to alkylating agents in the other. A brief review of previous experience with the use of rituximab in the treatment of WG is presented.

Abstract
The aim of this study was to determine the potential role of three IRF3 gene polymorphisms (rs2304204, rs7251 and rs2304207) with systemic lupus erythematosus (SLE). Our study population consisted of 610 patients with SLE and 730 healthy controls. All individual were of Spanish Caucasian origin. The IRF3 polymorphisms were genotyped using a PCR system with pre-developed TaqMan allelic discrimination assay. No statistically significant differences were found when allele and genotype distribution of rs2304204, rs7251 and rs2304207 polymorphisms were compared between patients with SLE and controls [overall P values: rs7251, P = 0.06; rs2304204, P = 0.26 and rs2304207, P = 0.36, by chi-squared test on a 3 x 2 contingency table. Overall allelic P values: rs7251, P = 0.8, OR (95%CI) = 1.03 (0.87-1.22); rs2304204, P = 0.2, OR (95%CI) = 1.12 (0.93-1.34) and rs2304207, P = 0.8, OR (95%CI) = 1.02 (0.82-1.26)]. In addition, no evidence of association with haplotypes and clinical features of SLE was found. Our data suggest that the IRF3 polymorphisms do not appear to play a major role in the susceptibility or severity of SLE in a Spanish population.

Abstract
OBJECTIVES The aim of this study was to evaluate the relevance of genetic variants of TLR5 (rs5744168) and TLR7 (rs179008) gene in systemic lupus erythematosus (SLE) in a Spanish population. MATERIAL AND METHODS Our study population consisted of 752 SLE patients and 1107 healthy controls. All individual were of Spanish Caucasian origin. The TLR5 and TLR7 polymorphisms were genotyped using a PCR system with pre-developed TaqMan allelic discrimination assay. RESULTS No statistically significant differences were observed when the allele and genotype distribution of TLR5 rs5744168 and TLR7 rs179008 polymorphisms was compared between SLE patients and healthy controls. A significant increase frequency in the CC genotype of the TLR5 rs5744168 polymorphism among SLE patients without nephritis was found (93% vs. 87% in SLE patients with nephritis, p=0.03, OR=2.11 95%CI 0.93-3.51). However, this difference did not reach statistical significance in the allele frequencies (p=0.08). CONCLUSION These results suggest that the tested variations of TLR5 and TLR7 genes do not confer a relevant role in the susceptibility or severity to SLE in the Spanish population.

Abstract
BACKGROUND Thrombocytopenia is a common haematological abnormality and no simple diagnostic test is available to diagnose thrombocytopenia pathogenesis. AIM To evaluate sensitivity and specificity of reticulated platelets (RP) as a diagnostic test for thrombocytopenia with increased thrombopoietic activity. DESIGN Prospective observational study in thrombocytopenic patients. METHODS A direct, whole-blood, dual-labelling flow cytometric method was used. Direct, whole-blood double coverage was achieved using a monoclonal anti-glycoprotein (GP)-III antibody (CD61 PerCP) for platelet identification and thiazole orange (Retic-count) as platelet mARN stain. RESULTS RP were measured in 101 thrombocytopenic patients and 104 non-thrombocytopenic controls. The mean RP percentage in 60 thrombocytopenic patients with no increased thrombopoietic activity was 7.5% (CI for 95%: 5.2-9.7) and RP absolute number was 3.2 x 10(9)/l (CI for 95%: 2.1-4.3). The mean RP percentage in 41 thrombocytopenic patients with increased thrombopoietic activity was 30.3% (CI for 95%: 25.1-35.5) and RP absolute number was 6.2 (CI for 95%: 4.8-7.7). The RP percentage cut-off for a diagnosis of thrombocytopenia with increased thrombopoietic activity was 11% [sensitivity 93%, specificity 85%, positive predictive value (PPV) 83%, negative predictive value (NPV) 95%]. CONCLUSION RP measurement by flow cytometry, directly from whole-blood, is a useful screening test to differentiate between thrombocytopenia with high or low thrombopoietic activity. A RP percentage in excess of 11%, has a high sensitivity and good specificity for a diagnosis of thrombocytopenia with increased thrombopoietic activity.

Abstract
The clinical characteristics and 3-month clinical outcome of 7,664 patients with acute deep vein thrombosis(DVT), 3,968 patients with pulmonary embolism(PE), and 2,287 with signs of both DVT and PE were compared. As compared to patients with DVT signs, PE patients were more commonly females, older and had less often cancer, prior VTE or recent surgery. By contrast, they had more often chronic lung disease,chronic heart failure or renal insufficiency. Patients with both DVT and PE signs were also more commonly females and older than those with only DVT signs, but they had more often a prior episode VTE, cancer, chronic lung disease, chronic heart failure or renal insufficiency. As for the 3-month clinical outcome,patients with PE signs had a significantly higher incidence of major bleeding, recurrent PE, fatal PE and overall death than those with only DVT signs,but a lower incidence of recurrent DVT. Besides, patients with DVT and PE signs had an even worse clinical outcome.

Abstract
OBJECTIVES To examine the clinical characteristics and outcomes of cancer patients with venous thromboembolism (VTE) in order to identify factors that place these patients at an increased risk for fatal pulmonary embolism (PE) or fatal bleeding. PATIENTS AND METHODS Registro Informatizado de la Enfermedad Trombo Embólica (RIETE) is a prospective registry of consecutive patients with symptomatic, objectively confirmed, acute VTE. RESULTS Up to January 2006, a total of 14 391 patients with symptomatic acute VTE were enrolled in RIETE, of whom 2945 (20%) had cancer. During the 3-month follow-up period the frequency of fatal PE in cancer patients was 2.6%, and that of fatal bleeding 1.0%. These frequencies were significantly higher than in VTE patients without cancer (1.4% and 0.3%, respectively). In patients with cancer, abnormal renal function, metastatic disease, recent major bleeding and recent immobility for >or= 4 days (42% of the 108 patients who died from PE or bleeding had recent immobility) were factors independently associated with an increased risk for both fatal PE and fatal bleeding. In addition, PE diagnosis on admission was an independent risk factor for fatal PE, while body weight < 60 kg was an independent risk factor for fatal bleeding. CONCLUSIONS Both fatal PE and fatal bleeding are more common in cancer patients with VTE than in those patients without cancer. In cancer patients, abnormal renal function, metastatic disease, recent major bleeding and recent immobility for >or= 4 days are associated with an increased risk for both fatal PE and fatal bleeding.

Abstract
OBJECTIVES To evaluate the prevalence and incidence of antimalarial myopathy in patients with rheumatic diseases treated with antimalarial drugs. METHODS Over a three year period, all patients with rheumatic diseases who were taking antimalarial drugs were studied. Serum muscle enzymes were assessed at the time of inclusion and every six months thereafter. Muscle strength, electromyography (EMG), and muscle biopsy were assessed in patients with a persistent muscle enzyme disturbances. RESULTS 119 patients were included (111 chloroquine, eight hydroxychloroquine). Of these, 22 (18.5%) had a persistent muscle enzyme disturbance: lactate dehydrogenase 19/22 (86%); creatine kinase 7/22 (32%), and aldolase 3/22 (14%). Findings of antimalarial myopathy were detected in 3/15 biopsied patients (20%) by light microscopy and in all 15 by electron microscopy. Eleven patients had myopathy at the time of inclusion (prevalence 9.2%) and four patients developed muscle injury during follow up (annual incidence 1.2%). Muscle weakness was observed in 8 of 15 patients with biopsy proven myopathy, giving a prevalence of clinical antimalarial myopathy of 6.7%. All these patients also had a myopathic pattern on electromyography. CONCLUSIONS The prevalence of antimalarial myopathy is higher than previously recognised when muscle enzyme determination is used as a screening method. When a persistent muscle enzyme disturbance is observed, clinical and electromyographic studies should be undertaken periodically to detect the development of clinical myopathy. In cases of clinical myopathy, an anatomical-pathological tissue study, including an ultrastructural study, is mandatory to confirm the diagnosis.

Abstract
We report the case o a 40-year-old male patient with "primary antiphospholipid syndrome" who developed ischemic cerebral infarctions and renal microangiopathy with infarction. A review of the literature on renal involvement in the primary antiphospholipid syndrome disclosed the differences from the antiphospholipid syndrome in the systemic lupus erythematosus. We describe the evolution of the patient at eight years, and we emphasize the importance of the treatment with warfarin. Also, we review the pathophysiology of severe secondary arterial hypertension.

Abstract
Some studies on discharge against medical advice (AMA) in general hospitals report a prevalence between 0.7-7% with 11-42% of this population identified as psychiatric patients. To study the sociodemographic and psychopathological features of patients who leave AMA, we performed a retrospective case-control comparison study of length of hospitalization and presence of psychiatric disturbances on patients who left AMA from the University General Hospital in Catalan Spain over a two-year period. An analysis of the hospital epidemiological discharge register and retrospective chart review for presence of psychiatric disturbances found that AMA prevalence was 0.34%, the total discharge number in the 2-year period being 41,648. AMA rates by medical department were 0.44% for the internal medicine department; 0.24% for surgery; 0.26% for orthopedic surgery, 0.32% for obstetrics-gynecology and 0.93% for rehabilitation. The mean age for AMA patients was 38.63 years, with a higher number of men (59.9%). A total of 45.8% AMA discharges were from the internal medicine department. No significant differences were found in the average length of hospitalization between the AMA and control groups. The presence of psychiatric pathology was significantly higher among the AMA group (P<.05). The prevalence of AMA at our hospital was low in comparison to the rates reported in the literature. The patient at high risk for AMA discharge is a young man with a history of psychiatric pathology, mainly narcotic dependence.

Abstract
Idiopathic pylephlebitis and primary sclerosing peritonitis are two highly unusual entities. To our knowledge, the association of the two diseases has not been described previously. We report a 42-year-old patient with a protein S deficiency who presented with fever and chills, in whom idiopathic pylephlebitis was diagnosed. A year later, the patient was readmitted because of recurrent vomiting and weight loss. An exploratory laparotomy yielded diagnosis of sclerosing peritonitis, which resolved after surgery. The short time interval between the processes suggests that they were related to each other, and also to the protein S deficiency.

Abstract
OBJECTIVE To identify survival prognostic factors and markers of morbidity among patients with systemic sclerosis (SSc). PATIENTS AND METHODS The study included 72 patients diagnosed with SSc. According to the extent of skin involvement, three groups of patients were established: group 1, without sclerosis and with sclerosis of fingers and neck; group 2, with sclerosis of face and distal to elbows and knees; group 3, with generalised sclerosis including the trunk. All patients were included in a study protocol to determine visceral involvement. Cumulative survival after first symptom has been estimated according to the Kaplan-Meier method. The association between a hypothetical prognostic factor and cumulative survival after first symptom was assessed by log rank test. The association between a hypothetical risk factor and the prevalence of severe morbidity was assessed by the odds ratio. Multiple logistic regression models were used to identify the main predictors of severe morbidity. RESULTS Survival was estimated to be 85% 10 years after first SSc symptom. Survival was higher among SSc patients with skin involvement distal to elbows and knees than among the rest of patients; a forced vital capacity (FVC) on spirometry lower than 70% of expected value was associated with a shorter survival, even after adjustment for diffuse SSc. Skin involvement proximal to elbows or knees was associated with a higher prevalence of severe morbidity (OR = 46.57; p < 0.001). According to a multiple logistic regression, severe morbidity was higher among patients with skin involvement proximal to knees or elbows (OR = 40.92; p < 0.001) or among patients with pulmonary hypertension detected by Doppler echocardiography (OR = 23.66 p < 0.001). CONCLUSIONS In patients with SSc the extent of skin sclerosis was found to be a determining factor on the prognosis. According to skin sclerosis extent two main subsets of SSc patients with different survival incidence and degree of morbidity could be clearly established: limited SSc, formed by patients with no skin sclerosis or with sclerosis distal to elbows and knees and diffuse SSc, formed by patients with skin sclerosis distal and proximal to elbows and knees. Moreover, lung involvement (FVC < 70% on survival study and pulmonary hypertension on morbidity study) was an important and independent prognostic factor.

Abstract
Renal involvement is unusual in giant cell (temporal) arteritis (GCA). Microscopic hematuria and minimal proteinuria responsive to steroid therapy have been described as the most frequent renal alterations. The nephrotic syndrome in GCA has been rarely reported. We describe 2 cases of GCA with nephrotic syndrome, one at the time of diagnosis, the other 2 years after treatment. Percutaneous renal biopsy in both cases disclosed secondary renal amyloidosis confirmed by permanganate sensitivity and immunohistochemical analysis. To our knowledge, cases of GCA and secondary amyloidosis have not been reported.

Abstract
Exclusively penial lymphatic affections can be considered a highly infrequent occurrence. In the absence of an scrotal oedema, an "elephantiac" involvement with tumoral appearance in the penis, is indeed exceptional. A clinical case is briefly commented here. It refers to a patient with a significant sociopathy who presented a lymphedema confined to the penis in its maximum expression (elephantiasis verrucosa nostras).

Abstract
PURPOSE To determine whether the features of the antiphospholipid syndrome (APS) are in any way influenced by the presence or absence of systemic lupus erythematosus (SLE). We followed up patients with 'primary' APS (PAPS) and APS secondary to SLE (APS plus SLE) with the objective of comparing laboratory and clinical events and of determining whether patients with PAPS would have evolution to SLE. PATIENTS AND METHODS A total of 114 patients from 3 European referral centers were included in this study. Fifty-six had APS plus SLE and 58 had PAPS. Laboratory and clinical data were collected during an average 2-year period. RESULTS Patients with PAPS and patients with APS plus SLE had similar clinical and laboratory profiles, with the exceptions of autoimmune hemolytic anemia, endocardial valve disease, neutropenia, and low C4 levels, all of which occurred more frequently in patients with APS plus SLE (p values: < 0.05, < 0.005, < 0.01, and < 0.001, respectively). On follow-up, 10 thrombotic episodes occurred in 10 patients, 8 of whom were receiving anticoagulant therapy. No patient with PAPS had either anti-DNA or anti-extractable nuclear antigen antibodies, and these patients had a significantly lower prevalence of antinuclear antibodies (41%) than patients with APS plus SLE (89%). CONCLUSIONS Patients with APS plus SLE and PAPS have similar clinical profiles, although heart valve disease, hemolytic anemia, low C4 levels, and neutropenia seem to be more common in patients with APS plus SLE. Patients with APS may develop further thrombotic events despite anticoagulation therapy.

In order to ascertain the incidence of monoclonal gammopathy (MG) in systemic lupus erythematosus (SLE), 120 SLE patients were evaluated. Four patients (3.3%), two of whom were under 50 years of age, were found to have a monoclonal immunoglobulin in their serum. Our data agree with the previous literature in demonstrating a higher incidence of MG in SLE patients in comparison with the general population. Neither the clinical importance nor the pathogenetic significance of this association is known.

Abstract
There are few studies addressing the frequency and etiology of anemia in progressive systemic sclerosis. Anemia is present in about 25% of these patients. Among the implicated causes are ferropenia, generally associated with gastrointestinal hemorrhage, and renal failure. In a considerable number of patients, the specific etiology of anemia remained unknown. We report a 59-year-old female with autoimmune hemolytic anemia and incomplete CREST syndrome. We emphasize the rarity of autoimmune hemolysis as a cause of anemia in systemic sclerosis, and we discuss its significance as indirectly supporting the possible autoimmune pathogenesis of that condition.
