Introduction: The GEM-CESAR trial is a potentially curative strategy for high-risk smoldering multiple myeloma (HRsMM) patients (pts) in which the primary endpoint is the achievement of bone marrow ...minimal residual disease (MRD) negativity. However, other methods of disease evaluation in serum such as heavy+light chain (HLC) assessment, with a potential complementary value to the IMWG response criteria, have also been tested.
Aim: To evaluate the performance of HLC assay in HRsMM pts at diagnosis and after consolidation, comparing the results with standard serological methods and Next Generation Flow (NGF) for the assessment of bone marrow MRD.
Patients and Methods: Ninety HRsMM pts included in the GEM-CESAR trial received six 4-weeks cycles of carfilzomib, lenalidomide and dexamethasone followed by high dose melphalan and 2 further cycles of consolidation with the same regimen. All pts received maintenance treatment with lenalidomide for up to 2 years. SPEP and IFE were performed using standard procedures. Serum IgGk, IgGl, IgAk and IgAl HLC concentrations were measured using Hevylite (The Binding Site Group Ltd, Birmingham, UK) on a SPA PLUS turbidimeter. HLC concentrations and ratios were considered abnormal if they were outside the 95% reference ranges provided by the manufacturer. MRD was analyzed by flow cytometry following EuroFlow recommendations (sensitivity, 2x10-6). Standard response assignment was carried out as per the IMWG guidelines. Hevylite responses were assigned and HLC-pair suppression was defined as in Michalet et al (Leukemia 2018).
Results:
Out of 90 HRsMM pts, 75 had monoclonal intact immunoglobulin and samples available at diagnosis (50 IgG and 25 IgA). HLC ratio was abnormal in 98% of IgG pts and in 100% of IgA pts. Response assessment by Hevylite and standard IMWG criteria were available in 62 pts post-consolidation (Table 1). A good agreement was found between the two methods (kappa quadratic weighting = 0,6327 (0,4016 - 0,8638)). Among 46 pts with assigned CR as per the IMWG response criteria, there were 3 and 8 pts in PR and VGPR according to the Hevylite method, respectively. In 62 cases, paired Hevylite and MRD assessment data were available. Concordant results were found in 72.5% of cases (45/62; HLC+/NGF+ in 15 and HLC-/NGF- in 30 cases) while in the remaining 27.4% of cases results were discordant (17/62; HLC-/NGF+ in 6 and HLC+/NGF- in 11 cases). Post-consolidation, 24, 25.8 and 42.3% of the 62 samples were positive by SPEP, NGF and Hevylite, respectively. HLC-pair suppression was identified in 13/62 pts; 10 had severe HLC-pair suppression at the end of consolidation. After a median follow-up of 32 months (8-128), 93% of pts remain alive and progression-free. Three patients that have already progressed had their responses assessed post-consolidation. The first pt was assigned VGPR by the standard IMWG criteria and PR by Hevylite and was MRD positive by NGF; the second pt was assigned CR by IMWG criteria and Hevylite but had severe HLC-pair immunosuppression and was MRD positive by NGF; the third pt was in CR by IMWG and HLC criteria and was MRD positive by MFC.
Conclusions: Moderate agreement was found between response assessment by Hevylite and the standard IMWG methods as well as between Hevylite and MRD assessment by NGF. Most discordances were a result of Hevylite detecting disease in samples negative by the standard methods, but longer follow-up is needed to ascertain its clinical value. HLC assessment could have anticipated the progression noted in 2 (out of 3) patients.

Cystic fibrosis neonatal screening (CFNS), based on double determination of immunoreactive trypsinogen (IRT IRT1/IRT2), has been available in Andalusia since May 2011. If screening is positive, a ...sweat test is performed, and if that is positive or inconclusive, genetic testing is requested.
To analyze CFNS, based on results from the first 4.5 years of the program.
Prospective descriptive study of neonates undergoing CFNS. IRT levels, sweat chloride, and mutations were recorded. Statistical analysis was performed using SPSS 12.0.
Between May 2011 and December 2016, 474,953 neonates underwent CFNS. Of these, 1087 (0.23%) had elevated IRT2. Since CFNS was introduced, 73 cases of cystic fibrosis were diagnosed; 60 were diagnosed by positive CFNS, and 13 were diagnosed by other means. In one case, the patient developed a typical clinical picture of cystic fibrosis, but had not undergone CFNS at the decision of the parents; the remaining 12 had a negative CFNS (false negatives). Of these, one patient was diagnosed before symptoms developed, as his twin brother had a positive CFNS result; another had chloride at the upper limit of normal, and was subsequently diagnosed with genetic testing before symptoms appeared; and 10 patients developed clinical signs and symptoms. Excluding patients with meconium ileus, sensitivity and specificity of the CFNS program were 85.71% and 99.78%, respectively. The incidence of the disease in Andalusia is 1/6506 live births.
These results are a basis for reflection on possible areas for improvement of the CFNS algorithm, and thought may be given to the introduction of genetic studies to increase sensitivity and reduce false positives.
Andalucía dispone de screening neonatal de fibrosis quística (SNFQ) desde mayo 2011, basado en doble determinación de tripsinógeno inmunorreactivo (TIR TIR1/TIR2). Si el screening es positivo realizamos un test del sudor y si es positivo o dudoso solicitamos genética.
Analizar el SNFQ, basado en los resultados de los primeros 4,5 años.
Estudio descriptivo prospectivo de los neonatos sometidos a SNFQ. Se recogen los niveles de TIR, cloruro en sudor, mutaciones. Mediante SPSS12.0 se realizó análisis estadístico.
Desde mayo 2011 a diciembre 2016, 474.953 neonatos fueron sometidos a SNFQ. Mil ochenta y siete (0,23%) presentaron TIR2 elevado. Desde la implantación del SNFQ se diagnosticaron 73 casos con fibrosis quística; 60 de ellos fueron diagnosticados mediante un SNFQ positivo, mientras que 13 no. Concretamente un paciente comenzó con clínica clásica de fibrosis quística y se comprobó que no se había realizado el SNFQ por decisión paterna; los 12 restantes tuvieron un SNFQ negativo (falsos negativos). De estos, un paciente fue diagnosticado presintomáticamente al tener su hermano gemelo con SNFQ positivo; otro con cloruro en el límite alto de la normalidad se diagnosticó presintomáticamente mediante genética; 10 pacientes comenzaron clínicamente. Excluyendo los pacientes con íleo meconial, la sensibilidad y especificidad del programa de SNFQ asciende al 85,71 y 99,78% respectivamente. La incidencia de la enfermedad en Andalucía es de 1/6.506 recién nacidos vivos.
Los presentes resultados nos permiten reflexionar sobre posibles áreas de mejoras adicionales del algoritmo del SNFQ, que debe pasar por la introducción de estudios genéticos para así aumentar la sensibilidad y disminuir los falsos positivos.
Introduction:SMM is an asymptomatic and heterogeneous plasma cell disorder. The Spanish Myeloma Group demonstrated that patients at high risk of progression benefit from early treatment with Rd. In ...addition, our preliminary results of the curative approach (GEM-CESAR) showed encouraging results (Mateos ASH 2017).
Aim: The primary end-point was to evaluate the Minimal Residual Disease negative (MRD-ve) rate by next generation flow (NGF) after induction and ASCT and the sustained MRD-ve rate at 3 and 5 yrs after ASCT as secondary end-points. Our aim was to increase the MRD -ve rate from 34% (reported in NDMM patients after VTD and ASCT) to 50%. As all patients have completed induction and ASCT, we report the results of the primary end point, efficacy and safety after induction and ASCT.
Methods: In this phase II single arm trial, 90 SMM patients at high-risk of progression (>50% at 2 yrs), younger than 70 yrs and transplant candidates were included. The high risk was defined by the presence of both ≥PC 10% and MC ≥3g/dL (Mayo criteria) or ifonly one criterion was present, patients must have a proportionof aberrant PCs within the total PCsBM compartment by immunophenotypingof 95% plus immunoparesis (Spanish criteria). Asymptomatic MM patients with any of the three biomarkers recently included into the definition of active MM were allowed to be included. Induction therapy consisted on six 4-weeks cycles of KRd in which K was given at dose of 36 mg/m2twice per week plus R at dose of 25 mg on days 1-21 and dexamethasone at dose of 40 mg weekly. Melphalan at dose of 200 mg/m2followed by ASCT was given as intensification therapy and three months later, patients received two KRd consolidation cycles followed by maintenance with R at dose of 10 mg on days 1-21 plus dex at dose of 20 mg weekly for up to 2 yrs
Results: Between June 2015 and June 2017, the 90 SMM patients at high risk of progression were recruited. Twenty-eight pts (32%) shared at least one of the new biomarkers predicting imminent risk of progression to MM.
The primary end point of the trial was met, since 55% of the patients who completed induction and ASCT achieved MRD -ve by NGF (sensitivity 3 x 10-6). Upon analyzing the results after induction, 88 patients completed the 6 induction cycles and were evaluable for response (two patients early discontinued): the ORR was 98% including 41% of ≥CR (32% sCR and 9% CR) and 41% of VGPR rate. Two patients were mobilization failures and one patient rejected ASCT. Two additional patients experienced biological progression before ASCT and went off the study. Eighty-three patients, therefore, proceeded to HDT-ASCT and were evaluable at day +100: the ORR was 100% including ≥CR in 63% of the patients (51% sCR and 12% CR) and VGPR rate in 23%. The MRD-ve rate increased from 31% after induction to 55% with the ASCT. No differences in outcome have been observed according neither to the definition of high risk (Mayo or Spanish model) nor ultra high risk SMM.
Concerning toxicity, during induction, G3-4 neutropenia and thrombocytopenia were reported in 5 (6%) and 10 pts (11%), respectively. G3-4 infections were the most frequent non-hematological AE observed in 16 pts (18%), followed by skin rash in 8 pts (9%). One patient reported G1 atrial fibrillation and another cardiac failure secondary to respiratory infection. Three patients reported hypertension (G2 in two and G3 in one). Thirteen patients required lenalidomide dose reduction whilst carfilzomib was not reduced in any patient. In four patients, dexamethasone was reduced. In all but two of the pts, PBSC collection was successful with a median of 4.10 x 106/Kg CD34 cells collected. All patients engrafted. Consolidation and maintenance phases are ongoing.
After a median follow-up of 17 months (5-36), 94% of patients remain alive and free of progression and 97% of them alive. Three patients experienced biological progression and discontinued the study: one of them was refractory to the rescue therapies and died and the other two are receiving rescue therapies. One additional patient died early during induction due to a massive ischemic stroke unrelated to the treatment.
Conclusions: Although longer follow-up is required, this “curative strategy for high risk SMM” continues being encouraging with an acceptable toxicity profile. The study has met its primary endpoint. The depth of response improved over the treatment: 63% of patients who completed induction and ASCT achieved ≥CR with a MRD-ve rate of 55%.

We evaluated the safety and viral rebound, after analytical treatment interruption (ATI), of vedolizumab and ART in recent HIV-1 infection. We used this model to analyze the impact of α4β7 on the ...HIV-1 reservoir size. Participants started ART with monthly Vedolizumab infusions and ATI was performed at week 24. Biopsies were obtained from ileum and caecum at baseline and week 24. Vedolizumab levels, HIV-1 reservoir, flow cytometry and cell-sorting and antibody competition experiments were assayed. Vedolizumab was safe and well-tolerated. No participant achieved undetectable viremia off ART 24 weeks after ATI. Only a modest effect on the time to achieve >1000 HIV-RNA copies/mL and the proportion of participants off ART was observed, being higher compared to historical controls. Just before ATI, α4β7 expression was associated with HIV-1 DNA and RNA in peripheral blood and with PD1 and TIGIT levels. Importantly, a complete blocking of α4β7 was observed on peripheral CD4+ T-cells but not in gut (ileum and caecum), where α4β7 blockade and vedolizumab levels were inversely associated with HIV-1 DNA. Our findings support α4β7 as an important determinant in HIV-1 reservoir size, suggesting the complete α4β7 blockade in tissue as a promising tool for HIV-cure combination strategies.We evaluated the safety and viral rebound, after analytical treatment interruption (ATI), of vedolizumab and ART in recent HIV-1 infection.

Introduction: Smoldering Multiple Myeloma (SMM) is an asymptomatic plasma cell disorder that includes patients with different risk of progression to Multiple Myeloma (MM). The Spanish Myeloma Group ...demonstrated that early treatment with Rd versus observation in SMM at high risk (HR) of progression resulted into a significant benefit in terms of progression to MM and overall survival. Our next step was to design this phase 2 trial with the potential goal of cure, defined by a sustained minimal residual disease (MRD) negativity for at least 5 years (yr).
Methods: In this phase 2 single-arm trial, 90 SMM patients (pts) at high-risk of progression (>50% at 2 yr), younger than 70 yr and transplant candidates were included. The HR was defined by the presence of both bone marrow plasma cells (PCs)≥ 10% and serum M-protein ≥3g/dL (Mayo) or ifonly one criterion was present, patients must have a proportionof aberrant PCs within the total PCs bone marrow compartment by immunophenotypingof 95% plus immunoparesis (Spanish). Asymptomatic MM patients with any of the three biomarkers that currently define active MM were allowed to be included, because the design of the trial was done before the publication (Lancet Oncol 2014). Induction therapy consisted on six 4-weeks cycles of KRd in which K was given at dose of 36 mg/m2 twice per week plus R at dose of 25 mg on days 1-21 and dexamethasone (dex) at dose of 40 mg weekly. Melphalan at dose of 200 mg/m2 followed by autologous stem-cell transplant (ASCT) was given as intensification therapy and three months later, patients received two KRd consolidation cycles followed by maintenance with R at dose of 10 mg on days 1-21 plus dex 20 mg weekly for up to 2 yr. MRD was evaluated by next-generation flow cytometry after induction, ASCT, consolidation and annually thereafter.
Results: the 90 planned patients were recruited between June 2015 and June 2017. Although 126 patients signed the informed consent (IC), there were 36 screening failures, including 21 (17%) pts due to the detection of lytic lesions by PET-CT or MRI (the most frequent exclusion criteria). The median age of the whole series was 59 yr. All pts were at HR according to the Mayo and/or Spanish models, including 28 pts (31%) that shared at least one of the new MM biomarkers (MDE).
Forty-three patients have completed the 6 induction cycles and are evaluable for response: the ORR was 98% including 46% of ≥CR (37% sCR and 9% CR) and 37% of VGPR. MRD by NGF was evaluated in 34 out of these 43 pts and was negative in 13 (38%). Twenty-nine patients have received ASCT and were evaluable at 3 months: the ORR was 100% including ≥CR in 69% of the patients (65% sCR and 3% CR) and VGPR rate in 21%. MRD was negative in 17 out of these 29 patients (58%). Nineteen patients have completed the two planned consolidation cycles and 85% of them are in ≥CR, including sCR in 74%, CR in 11% and VGPR in 16%.
As far as toxicity during induction is concerned, , G3-4 neutropenia and thrombocytopenia were reported in 4 (4%) and 2 pts (2%), respectively. G3-4 infections were the most frequent non-hematological adverse events (AE), observed in 9 pts (10%), followed by skin rash in 7 pts (8%). With regard to cardiovascular events, 1patient reported atrial fibrillation and another cardiac failure, both of G1, and 2 patients reported G2 arterial hypertension. In all but one of the pts, peripheral blood stem cell collection was successful, with a median number of CD34+ cells collected of 6,79 x 106/Kg. Engraftment occurred in all patients and the median number of CD34+ infused was 3.29 x 106/Kg. During consolidation, 2 pts developed G3-4 neutropenia, 3 pts G3-4 infections and 1 pt skin rash.
After a median f/u of 13 months (1-108), 98% of patients remain free of progression and alive. Three patients early discontinued: one withdrew the IC; and two treatment unrelated deaths, one during induction due to a massive ischemic stroke and the other one because of refractory disease after induction. No discontinuations due to related-AE have been reported.
Conclusions: Although longer follow-up is required, this “curative strategy for high-risk SMM” seems to be encouraging. The depth of response improved along with the duration of treatment, achieving up to 85% of ≥CR in patients who completed induction, ASCT and consolidation, with an acceptable safety profile. Interestingly, novel imaging techniques at screening allowed us to identify up to 17% of MM that would have been considered SMM with the conventional criteria.

Newborn Screening Programs (NSP) in Spain were born in the city of Granada in 1968. Till the 1980s, they were developed around the so-called "National Plan for Preventing Subnormality", covering up ...to 30% of the Spanish newborns. From 1982, when the health system management was transferred to the different autonomous regions, the NSP began to expand, and the bases to transform them into an organized and multidisciplinary activity, integrated and coordinated from the National Health System were settled. Despite this expansion, it is not until the 1990s when their coverage reaches almost 100% newborns in Spain. NSP grew up asymmetrically across the different autonomous regions. In 2005 and 2006 the scientific societies SEQC (Spanish Society of Clinical Chemistry) and AECNE (Spanish Society of Newborn Screening), coordinated by the Health Promotion Area of the General Directorate of Public Health, gathered together the necessary information to elaborate a report on the NSP in Spain addressed to the Interterritorial Council of the National Health System. In July 2013, that Council approved the seven diseases that should be part of each region newborn screening panel, being the first step towards the NSP harmonization in Spain. Currently, the NSP include between 8 and 29 diseases in their panels, thus more still more efforts are needed in order to achieve a higher uniformity.
Older people achieve lower levels of antibody titers than younger populations after Covid-19 vaccination and show a marked waning humoral immunity over time, likely due to the senescence of the ...immune system. Nevertheless, age-related predictive factors of the waning humoral immune response to the vaccine have been scarcely explored. In a cohort of residents and healthcare workers from a nursing home that had received two doses of the BNT162b2 vaccine, we measured specific anti-S antibodies one (T1), four (T4), and eight (T8) months after receiving the second dose. Thymic-related functional markers, including thymic output, relative telomere length, and plasma thymosin-α1 levels, as well as immune cellular subsets, and biochemical and inflammatory biomarkers, were determined at T1, and tested for their associations with the magnitude of the vaccine response (T1) and the durability of such response both, at the short- (T1-T4) and the long-term (T1-T8). We aimed to identify age-related factors potentially associated with the magnitude and persistence of specific anti-S immunoglobulin G (IgG)-antibodies after COVID-19 vaccination in older people.
Participants (100% men, n = 98), were subdivided into three groups: young (< 50 years-old), middle-age (50-65 years-old), and older (≥65 years-old). Older participants achieved lower antibody titers at T1 and experienced higher decreases in both the short- and long-term. In the entire cohort, while the magnitude of the initial response was mainly associated with the levels of homocysteine β (95% CI); - 0.155 (- 0.241 to - 0.068); p = 0.001, the durability of such response at both, the short-term and the long-term were predicted by the levels of thymosin-α1 - 0.168 (- 0.305 to - 0.031); p = 0.017, and - 0.123 (- 0.212 to - 0.034); p = 0.008, respectively.
Higher plasma levels of thymosin-α1 were associated with a lower waning of anti-S IgG antibodies along the time. Our results suggest that plasma levels of thymosin-α1 could be used as a biomarker for predicting the durability of the responses after COVID-19 vaccination, possibly allowing to personalize the administration of vaccine boosters.
Abstract Objective To determine whether an intervention based on patient-practitioner communication is more effective than usual care in improving diabetes self-management in patients with type 2 ...diabetes with low educational level. Methods 12-month, pragmatic cluster randomised controlled trial. Nine physicians and 184 patients registered at two practices in a deprived area of Granada (Andalusia, Spain) participated in the study. Adult patients with type 2 diabetes, low educational level and glycated haemoglobin (HbA1c) > 7% (53.01 mmol/mol) were eligible. The physicians in the intervention group received training on communication skills and the use of a tool for monitoring glycaemic control and providing feedback to patients. The control group continued standard care. The primary outcome was difference in HbA1c after 12 months. Dyslipidaemia, blood pressure, body mass index and waist circumference were also assessed as secondary outcomes. Two-level (patient and provider) regression analyses controlling for sex, social support and comorbidity were conducted. Results The HbA1c levels at 12 months decreased in both groups. Multilevel analysis showed a greater improvement in the intervention group (between-group HbA1c difference= 0.16; p = 0.049). No statistically significant differences between groups were observed for dyslipidaemia, blood pressure, body mass index and waist circumference. Conclusions In this pragmatic study, a simple and inexpensive intervention delivered in primary care showed a modest benefit in glycaemic control compared with usual care, although no effect was observed in the secondary outcomes. Further research is needed to design and assess interventions to promote diabetes self-management in socially vulnerable patients.
Research is an essential element in the practice of healthcare, and hospitals play a fundamental role in its promotion. Research in hospitals can improve the quality of care, knowledge of diseases ...and the discovery of new therapies. Hospitals can conduct research in various fields, including basic research, clinical research, population-based research and even hospital management research. The findings of hospital research can be directly applied to clinical practice and management, thereby enhancing the quality of patient care, a central paradigm in translational health. This article details the experience of the National Cancer Institute of Chile over the past 8 years in its role as a high-complexity public hospital, specialised institute, healthcare centre, teaching institution, and research facility.
