Abstract
OBJECTIVES To report healthcare resource utilization (HCRU) and safety outcomes in systemic light chain (AL) amyloidosis from the EMN23 study. MATERIALS AND METHODS The retrospective, observational, multinational EMN23 study included 4,480 patients initiating first-line treatment for AL amyloidosis in 2004-2018 and assessed, among other objectives, HCRU and safety outcomes. HCRU included hospitalizations, examinations, and dialysis; safety included serious adverse events (SAEs) and adverse events of special interest (AESIs). Data were descriptively analyzed by select prognostic factors (e.g., cardiac staging by Mayo2004/European) for 2004-2010 and 2011-2018. A cost-of-illness analysis was conducted for the UK and Spain. RESULTS HCRU/safety and dialysis data were extracted for 674 and 774 patients, respectively. Of patients with assessed cardiac stage (2004-2010: 159; 2011-2018: 387), 67.9% and 61.0% had ≥ 1 hospitalization, 56.0% and 51.4% had ≥ 1 SAE, and 31.4% and 28.9% had ≥ 1 AESI across all cardiac stages in 2004-2010 and 2011-2018, respectively. The per-patient-per-year length of hospitalization increased with disease severity (cardiac stage). Of patients with dialysis data (2004-2010: 176; 2011-2018: 453), 23.9% and 14.8% had ≥ 1 dialysis session across all cardiac stages in 2004-2010 and 2011-2018, respectively. The annual cost-of-illness was estimated at €40,961,066 and €31,904,386 for the UK and Spain, respectively; dialysis accounted for ∼28% (UK) and ∼35% (Spain) of the total AL amyloidosis costs. CONCLUSIONS EMN23 showed that the burden of AL amyloidosis is substantial, highlighting the need for early disease diagnosis and effective treatments targeting the underlying pathology.

Abstract
Smoldering multiple myeloma (SMM) is an asymptomatic precursor to active multiple myeloma (MM). The aim of this study was to report clinical characteristics and outcomes of patients with SMM stratified based on their risk of progression to MM using the Mayo 20/2/20 criteria. Data were leveraged from the Czech Myeloma Group Registry of Monoclonal Gammopathies (RMG). Key outcomes included progression-free survival from SMM diagnosis to active MM diagnosis or death (PFS), progression-free survival from SMM diagnosis to progression on first line (1 L) MM treatment or death (PFS2), and overall survival (OS). Of 498 patients, 174 (34.9%) were classified as high risk and 324 (65.1%) as non-high risk. Median follow-up was approximately 65 months. During follow-up, more patients in the high-risk vs non-high-risk group received 1 L MM treatment (76.4% vs 46.6%, p < 0.001). PFS, PFS2, and OS were significantly shorter in high-risk vs non-high-risk patients (13.2 vs 56.6 months, p < 0.001; 49.9 vs 84.9 months, p < 0.001; 93.2 vs 131.1 months, p = 0.012, respectively). The results of this study add to the growing body of evidence that patients with high-risk vs non-high-risk SMM have significantly worse outcomes, including OS.

Abstract
INTRODUCTION Chronic graft-versus-host disease (GVHD) is a life-threating complication of allogeneic hematopoietic stem cell transplantation (HSCT) leading to high morbidity and quality of life issues. We conducted a systematic literature review on the patient reported symptom burden of chronic GVHD. AREAS COVERED English-language articles published between 2005 and November 2018 were searched using CENTRAL, EMBASE and MEDLINE. Studies that used the 2005 or 2015 National Institute of Health consensus criteria for the diagnosis and staging of chronic GVHD were included. EXPERT OPINION Patient reported symptom burden was widely assessed in the literature (n = 38). The Lee Chronic GVHD Symptom Scale was the most frequently used instrument (n = 28), followed by the NIH Patient-reported Symptom scores (n = 11). Association of symptom burden with clinical outcome assessment endpoints (e.g. mortality) and with quality of life measures was investigated by fairly low number of studies with limited generalizability. By systematically investigating the influencing factors of symptom burden this review helps to better understand patients' perceptions and may help improving the management and care of chronic GVHD. However, data on influencing factors was quite diverse, which indicates that specific questions identified as research gaps need to be incorporated in randomized clinical trials in a more systematic way.

Abstract
AIMS In Spain, the first line treatment of hyperphosphatemia in Chronic Kidney Disease (CKD) consists of calcium-based phosphate binders (CB). However, their use is associated with vascular calcification and an increased mortality risk. The aim of this study was to assess the incremental cost-effectiveness of second-line Lanthanum Carbonate (LC) treatment in patients not responding to CB (calcium carbonate and calcium acetate). MATERIAL AND METHODS A lifetime Markov model was developed considering three health states (predialysis, dialysis and death). Transitions between states and efficacy data were obtained from randomized clinical trials and the European Dialysis and Transplant Association Annual report. Mortality rate was adjusted with the relative risk related to serum phosphorus levels. According to the Spanish healthcare system perspective, only medical direct costs were considered. Dialysis costs (2013 prices in Euros) were obtained from diagnosis-related groups. Drug costs were derived from ex-factory prices, adjusted with 7.5% mandatory rebate. Quality of life estimates were based on a published systematic review. Costs and benefits were discounted at 3%. Deterministic and probabilistic sensitivity analyses (PSA) were conducted. RESULTS At the end of simulation, costs per patient with LC therapy were <euro>1,169 and <euro>5,044 with CB alone. 4.653 Quality Adjusted Life Years (QALYs) were gained per patient treated with LC, and 4.579 QALYs with CB. CB therapy is dominated by the LC strategy (i.e. lower costs, higher QALYs). Assuming a <euro>30,000/QALY threshold, LC was dominant in 100% of PSA simulations. CONCLUSIONS LC is a cost-effective second line treatment of hyperphosphatemia in CKD patients irrespective of dialysis status in Spain.

Abstract
Future costs are not usually included in economic evaluations. The aim of this study was to assess the extent of published economic analyses that incorporate future costs. A systematic review was conducted of economic analyses published from 2008 to 2013 in three general health economics journals: PharmacoEconomics, Value in Health and the European Journal of Health Economics. A total of 192 articles met the inclusion criteria, 94 of them (49.0%) incorporated future related medical costs, 9 (4.2%) also included future unrelated medical costs and none of them included future nonmedical costs. The percentage of articles including future costs increased from 2008 (30.8%) to 2013 (70.8%), and no differences were detected between the three journals. All relevant costs for the perspective considered should be included in economic evaluations, including related or unrelated, direct or indirect future costs. It is also advisable that pharmacoEconomic guidelines are adapted in this sense.

Abstract
INTRODUCTION The prevalence of Hepatitis C (HCV) in Spain is 2,5%, with a high morbimortality rate. Triple therapy based on telaprevir plus peginterferon/ribavirin ([T/PR]) has demonstrated to be an effective approach in treatment-naïve G1-HCV patients. This analysis evaluated, through a Markov model, the incremental cost-effectiveness ratio of triple therapy compared to peginterferon/ ribavirin ([PR]) alone in naïve patients depending on fibrosis stage, from the Spanish Healthcare Authorities perspective. METHODS Efficacy results and adverse events incidence were based on the combined results of ADVANCE and OPTIMIZE studies. Adverse events and disease-related costs (€, 2014) were built up from panel expert opinion except from transplant and post-transplant costs, taken from published data. Drug costs were obtained from national databases and adjusted for the mandatory deduction. Outcomes and costs were both discounted at 3%/year. RESULTS The analysis shows higher costs and improved outcomes associated with [TR/PR] relative to [PR] alone, resulting in an incremental cost-effectiveness ratio (ICER) of €18,288/ QALY for all the cohort, €14,152QALY for moderate fibrosis, €11,364QALY for bridging fibrosis, €15,929/QALY for cirrhosis. Over a lifetime period, the use of [T/PR] could avoid 12 cirrhosis and 4 liver transplants per 1,000 patients compared to [PR] alone. The probabilistic analysis, following 10,000 Montecarlo simulations, demonstrated the probability of an ICER below a €30,000/QALY gained threshold of 69%. At a willingness- to-pay of €30,000/QALY, [T/PR] could be considered as an efficient option compared with [PR] alone for treatment-naïve genotype 1 HCV patients, over a lifetime horizon.

Abstract
INTRODUCTION Due to the aging population in developed countries, epidemiological studies show an increasing tendency to the prevalence of epilepsy in the elderly. PATIENTS AND METHODS During 54 months, we have studied the electroclinical and neuroimaging features in outpatients older than 60, with active epilepsy. Every patient was interviewed by one of the authors. Then, we have reviewed the medical records about the clinical features, EEG and neuroimaging (NI) studies and seizures frequency (SF) outcome. Differences in crude proportions were assessed by chi 2 test for independence by 2 x 2 tables. RESULTS The study was been performed in 78 patients with 70.3 +/- 7.3 years of mean age at review. Partial seizures were significantly related with an higher SF at onset and, in the series of complex partial seizures was more frequent a temporal EEG topography. There was predominance of men, NI abnormal, symptomatic etiology and SF at onset > or = 1 by day in that patients who started their epilepsy after 60 years. A 51.3% was seizures-free in the last year and in 80% the SF was improved a 50% or more from the beginning. CONCLUSION A significantly greater percentage of patients remained with seizures in four cases: in those with a SF at onset greater than 1 every day, in those suffering complex partial seizures, in women and in patients with temporal EEG topography.

Abstract
INTRODUCTION AND MATERIAL During 54 months, we have studied the electro-clinical and neuroimaging features in outpatients with active epilepsy. Each patient was interviewed for one of us. Then, we have reviewed the medical records about both the clinical featuring. EEG and neuroimaging (NI) studies and seizures frequency (SF) outcome. Differences in crude proportions were assessed by chi 2 test for independence by 2 x 2 tables. RESULTS AND CONCLUSIONS It has been 207 patients with 49 +/- 19.6 years of mean age at review. Partial seizures was significantly related with both a higher SF at onset and politherapy. Also, with a focal EEG distribution but only in case of complex partial seizures. Abnormal NI was significantly more frequent in oldest patients. A greater proportion of patients were in politherapy in four situation: SF at onset > 1 by day, a focal EEG distribution, duration of epilepsy longer than 20 years and age of onset lesser than 60 years. A 37.2% was seizures-free in the last year and in 34% the SF was improved a 50% or more from the beginning. A significantly greater proportion of patients was following with seizures in four cases: when the SF at onset has been > or = 1 by day, being partial seizures, women and having politherapy.

Abstract
INTRODUCTION In complex partial crises (CPC) some characteristics of the way in which they occur may be helpful in localizing the focus of origin in the cerebral cortex. Thus, the appearance of any kind of status epilepticus will not predominate depending on the origin of the epileptic focus, but the complex partial state will be rare when the origin is temporal and more frequent when the origin is frontal. The appearance of CPC in a cluster form is, on the other hand, characteristic of crises originating in the frontal lobe. MATERIAL AND METHODS We review the clinical history of 151 epileptics with CPC, evaluating the way in which the crises appear, together with other clinical data. We define the start of the crisis in a specific lobe, when this was the site of maximum voltage of the epileptic anomaly or of maximum phase opposition. RESULTS 10% of the patients showed grouping of their CPC; in the remainder the appearance was isolated, 15% showed status epilepticus at some point in their illness. We found a statistical difference when relating this to the anomalous topography of the EEG; between 15% and 42% more patients with status epilepticus were counted when the topography of the anomaly in the EEG was extratemporal. There was also between 37.2% and 76.4% more patients with cluster crises in the cases with an extratemporal focus.

Abstract
Neuro-imaging studies (NI) in patients with complex partial seizures (CPC) demonstrate the epileptogenicity of a more or less localized underlying lesion. Correlation with the topography of the EEG focus permits affirmation of the origin. We analyze anomalies on NI and on the EEG of 151 patients with CPC. The EEG was abnormal in 128 and showed a unilateral epileptic focus in 117. NI was focal and unilateral in 72 of the 102 abnormal cases. Topographic correlation was 78.5%. This close correlation in our series makes us consider the localized lesions to be the probable aetiological factor.

Abstract
With the appearance of MR, a great advance has been made in the study of the aetiology of epilepsy. This technique can show anomalies not detected in CT scans, obtain images of multiple planes, improve the differentiation of cerebral tissues and allow improved visualization of the temporal lobe, making it very useful in the study of patients with complex partial crises (CPC). We studied 151 epileptics with CPC by means of CT scan and MR in all cases; the anomolous topography was the same in all cases, but the diagnosis was not. In patients with a previously normal CT scan, on MR anomalies were detected in 24 cases. We found a statistical differences on evaluation of the MR anomaly depending on whether the CT scan was normal or abnormal. Statistical differences were also found when there were a greater number of anomalies on MR depending on the frequency of crises at the onset of the disorder.

Abstract
The authors evaluated the type of neurological involvement existing in patients with Behçet's syndrome over a 10 year period. Nine patients presenting several bouts with neurological symptomatology were studied with headache being clinically predominant followed in order of frequency by sensitive and/or motor ictal pictures. Suspected localization was both hemispheric and brain stem. No diagnostic test was able to clear up the origin of the lesions in the first stages of the disease, however the authors were able to observe, upon performing visual and/or brain stem evoked potentials and nuclear magnetic resonance at the time of the control, that several asymptomatic patients showed alterations in both tests. Thus, the value of the above mentioned tests must be emphasized in the follow up and control of neuro-Behçet's disease.

Abstract
The indications for endomyocardial biopsy were evaluated from 116 consecutive cases. The diagnostic value of this invasive but well tolerated procedure was in agreement with data from the literature. An accurate diagnosis, unforseeable in 8% of the patients, was established in 12%. The diagnosis of apparently primary myocardiopathy with ventricular dilatation was confirmed in 45 out of 59 cases; there were 3 cases of myocarditis, 3 cases of restrictive cardiopathy (haemochromatosis, fibroplastic endocarditis) and 1 case of hypertrophic cardiopathy. No tissue abnormality was noted in 6 cases. An accurate diagnosis was obtained by biopsy in 1 case of "eosinophilic lung" without overt cardiac involvement. In malignant diseases treated with anthracyclines in doses reaching maximal theoretical total dosage (30 patients), severe tissue lesions were present in 10% of the cases, incipient haemochromatosis in 16.6% and subendocardial fibrosis in 3.3%. However, total doses of up to 600 mg/m2 could be administered to 90% of the patients. Myocardial lesions could be demonstrated in 1 of 2 patients with collagen disease. Endomyocardial biopsy therefore seems to be justified in myocardiopathies with ventricular dilatation, in some collagen diseases with a tendency to cardiac involvement and to monitor treatment with anthracyclines in total doses higher than the theoretical maximum dosage.
