Aim
Joint damage due to haemarthrosis can be effectively monitored with point‐of care ultrasound using the Haemophilia Early Arthropathy Detection with US (HEAD‐US) scoring system. A post hoc ...comparative analysis of the joint status of patients with severe haemophilia A (HA) or B (HB) was performed.
Methods
The databases of two observational, cross‐sectional studies that recruited patients with HA or HB from 12 Spanish centres were analysed to compare the status of the elbows, knees and ankles in patients with severe disease according to treatment modality. The HEAD‐US score was calculated in both studies by the same trained operators.
Results
Overall, 95 HA and 41 HB severe patients were included, with a mean age of 35.2 ± 11.8 and 32.7 ± 14.2 years, respectively. The percentage of patients who received prophylaxis, over on‐demand (OD) treatment, was much higher in HA (91.6%) than in HB (65.8%) patients. With a similar number of target joints, the HEAD‐US score was zero in 6.3% HA and 22.0% HB patients (p < .01), respectively. The HA population showed significantly worse HEAD‐US scores. Whilst osteochondral damage occurred more frequently in patients OD or tertiary prophylaxis, our data suggest that articular damage is less prominent in primary/secondary prophylaxis, regardless of the type of haemophilia. These latter treatment modalities were also associated with a lower prevalence of synovial hypertrophy, particularly in HB patients.
Conclusion
This post hoc analysis indicates that joint status seems to be significantly influenced by haemophilia type (HA or HB) and treatment modality in these severe Spanish populations with severe disease. Continuing HEAD‐US monitoring for the early detection and management of intra‐articular abnormalities, as well as more efficiently tailored therapies should be warranted.
Introduction
The Haemophilia Early Arthropathy Detection with Ultrasound (HEAD‐US) system and scoring scale has proven to be an accurate and time‐efficient imaging method for identifying joint damage ...in patients with haemophilia.
Aim
Observational, multicentre, cross‐sectional study conducted in 8 centres in Spain that assessed the joint status of adult patients with severe haemophilia A (SHA) using HEAD‐US.
Methods
Joint status of the elbow, knee and ankle was evaluated in adults with SHA receiving on‐demand (OD) treatment, or primary (PP), secondary (SP), tertiary (TP) or intermittent (IP) prophylaxis.
Results
Of the 95 patients enrolled, 87 received prophylaxis (6.3% PP, 38.9% SP, 43.2% TP and 3.2% IP). Mean age was 35.2 years, and 59% of patients had not undergone image testing in the last year. The HEAD‐US score was 0 in all joints in 6.3% of patients. The ankle was the most affected joint, regardless of treatment regimen. Patients receiving OD treatment, TP or IP had the overall worst scores, mainly in the ankles and elbows; a similar but milder profile was observed in patients on SP; and patients on PP had the best score in all joints.
Conclusion
Joint function may be effectively preserved in patients with SHA on PP, but OD treatment or later initiation of prophylaxis does not seem to prevent progression of arthropathy. Disease worsening was observed in patients OD, TP or IP, most often affecting ankles and elbows. Closer ultrasound imaging monitoring may improve management of these patients.
Primary immune thrombocytopenia (ITP) is a complex autoimmune disease whose hallmark is a deregulation of cellular and humoral immunity leading to increased destruction and reduced production of ...platelets. The heterogeneity of presentation and clinical course hampers personalized approaches for diagnosis and management. In 2021, the Spanish ITP Group (GEPTI) of the Spanish Society of Hematology and Hemotherapy (SEHH) updated a consensus document that had been launched in 2011. The updated guidelines have been the reference for the diagnosis and management of primary ITP in Spain ever since. Nevertheless, the emergence of new tools and strategies makes it advisable to review them again. For this reason, we have updated the main recommendations appropriately. Our aim is to provide a practical tool to facilitate the integral management of all aspects of primary ITP management.
Eltrombopag is safe and effective in primary chronic ITP. However, lack of clinical trials avoids a clear demonstration of its utility in newly diagnosed and persistent ITP. Our aim here is to report ...Spanish results for this type of patients. We retrospectively evaluated 220 adult primary ITP patients. According to standard definition, patients were allocated to newly diagnosed (
n
= 30), persistent (
n
= 30), and chronic (
n
= 160) ITP. Groups were homogenous regarding most relevant parameters. 180 (90%) of 220 patients achieved a platelet response (R) with 167 (75.9%) complete responses (CR) after a 15-month follow-up. No statistical significant differences among groups but a trend towards a greater efficacy in newly diagnosed ITP were observed (93.3% of responses with 86.7% of CR). Efficacy in persistent ITP (83.3% of responses with 80.0% of CR) and chronic ITP (79.4% of responses with 73.1% of CR) was similar. 70 patients (31.8%) experienced adverse events. 15 of them were grade 3–4. Most common adverse effects were headache and hepatobiliary laboratory abnormalities (HBLAs). One persistent ITP had a venous thrombosis and one chronic ITP had grade II myelofibrosis. We consider Eltrombopag use for the early stage ITP as effective and safe as it is in chronic ITP.
Aim
The use of musculoskeletal ultrasound (MSK‐US) following protocols for haemophilic arthropathy and the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD‐US) score can help standardize ...monitoring in haemophilia. This study evaluated the joint status (elbows, knees and ankles) of patients with haemophilia B (HB) in Spain using MSK‐US and the HEAD‐US score.
Methods
Haemophilia B patients ≥14 years old were included in this observational, multicentre, cross‐sectional study, regardless of their clinical condition, HB severity and treatment received. Two blinded observers were involved in image acquisition and scoring in each centre.
Results
Eighty‐two patients from 12 centres were enrolled: 27% mild HB, 23% moderate, 50% severe HB. Mean age was 38.9 ± 16.4 years, 60% were treated on demand (OD) and 40% were on prophylaxis. HEAD‐US was zero in all joints in 28.6% OD patients and 36.4% on prophylaxis. Mean scores significantly worsened with HB severity, except for the left knee. Patients on primary and secondary prophylaxis had significantly better joint health vs OD patients in all joints, except the right ankle. Among OD patients, those with severe disease presented significantly worse scores in all HEAD‐US items related to permanent damage.
Conclusion
Joint status of HB patients in Spain is influenced by severity and treatment modality, related to the development of arthropathy, which appears prevalent in OD patients with severe HB. Routine assessment with an imaging tool such as ultrasound and HEAD‐US system may help to improve joint health by personalizing and adjusting treatment in this population.
To evaluate if the detection of N antigen of SARS-CoV-2 in plasma by a rapid lateral flow test predicts 90-day mortality in COVID-19 patients hospitalized at the wards.
The presence of N-antigenemia ...was evaluated in the first 36 hours after hospitalization in 600 unvaccinated COVID-19 patients, by using the Panbio COVID-19 Ag Rapid Test Device from Abbott (Abbott Laboratories Inc., Chicago, IL, USA). The impact of N-antigenemia on 90-day mortality was assessed by multivariable Cox regression analysis.
Prevalence of N-antigenemia at hospitalization was higher in nonsurvivors (69% (82/118) vs. 52% (250/482); p < 0.001). The patients with N-antigenemia showed more frequently RNAemia (45.7% (148/324) vs. 19.8% (51/257); p < 0.001), absence of anti-SARS-CoV-2 N antibodies (80.7% (264/327) vs. 26.6% (69/259); p < 0.001) and absence of S1 antibodies (73.4% (240/327) vs. 23.6% (61/259); p < 0.001). The patients with antigenemia showed more frequently acute respiratory distress syndrome (30.1% (100/332) vs. 18.7% (50/268); p = 0.001) and nosocomial infections (13.6% (45/331) vs. 7.9% (21/267); p = 0.026). N-antigenemia was a risk factor for increased 90-day mortality in the multivariable analysis (HR, 1.99 (95% CI,1.09–3.61), whereas the presence of anti-SARS-CoV-2 N-antibodies represented a protective factor (HR, 0.47 (95% CI, 0.26–0.85).
The presence of N-antigenemia or the absence of anti-SARS-CoV-2 N-antibodies after hospitalization is associated to increased 90-day mortality in unvaccinated COVID-19 patients. Detection of N-antigenemia by using lateral flow tests is a quick, widely available tool that could contribute to early identify those COVID-19 patients at risk of deterioration.

To determine whether treatment with eliglustat produces, in adult GD1 patients, ans optimal response in daily clinical practice.
We designed a real-life study with 2 years of follow-up (TRAZELGA GEE-ELI-2017-01) to uniformly evaluate the response and adverse events to eliglustat treatment. This study, conducted in 30 patients across Spain and previously treated with other therapies, included the evaluation of safety and efficacy by assessing visceral enlargement, bone disease (DEXA and T and Z scores), concomitant treatments and adverse events, as well as a quality of life evaluation (SF-36). In addition, the quantification of classical biomarkers (chitotriosidase activity, CCL18/PARC and glucosylsphingosine (GluSph)) and new candidates for GD biomarkers (YKL-40, cathepsin S, hepcidin and lipocalin-2 determined by immunoassay) were also assessed. Non-parametric statistical analysis was performed and p < 0.05 was considered statistically significant.
Thirty patients were enrolled in the study. The median age was 41.5 years and the male-female ratio was 1.1:1. 84% of the patients had received ERT and 16% SRT as previous treatment. The most common symptoms at baseline were fatigue (42%) and bone pain (38%), no patient had a bone crisis during the study, and two years after switching, 37% had reduced their use of analgesics. Patient-reported outcomes showed a significant increase in physical function scores (p = 0.027) and physical pain scores (p = 0.010). None of the enrolled patients discontinued treatment due to adverse events, which were mild and transient in nature, mainly gastrointestinal and skin dryness. None of the biomarkers show a significant increase or decompensation after switching. CCL18/PARC (p = 0.0012), YKL-40 (p = 0.00004) and lipocalin-2 (p = 0.0155) improved after two years and GluSph after one year (p = 0.0008) and two years (p = 0.0245) of oral therapy.
In summary, this real-life study, showed that eliglustat maintains stability and can improve quality of life with few side effects. Significant reductions in classic and other novel biomarkers were observed after two years of therapy.
Background: Successful discontinuation of eltrombopag in certain immune thrombocytopenia (ITP) patients after complete response has already been demonstrated. However, the frequency of this ...phenomenon and type of candidate patients are still matter of discussion. Moreover, possibility of long term discontinuation responses is not clearly established.
Methods: Here we retrospectively evaluated our whole cohort of 508 adult patients (aged 18 years or more) with primary ITP treated with eltrombopag included in the Spanish Eltrombopag Registry with a focus on the patients who achieved a durable (at least six months) platelet response after stopping eltrombopag. Successful discontinuation of eltrombopag (SDOE) was defined as those patients who reached remission and maintained platelet counts ≥ 50x109/l for at least 6 months in absence of eltrombopag or any rescue therapies administered. Long term discontinuation of eltrombopag (LTDOE) was defined as those patients who reached remission and maintained platelet counts ≥ 50x109/l for at least 36 months in the absence of eltrombopag or any rescue therapies administered. The study was approved by the Hospital Universitario de Burgos Ethics Committee and fulfilled Helsinki declaration standards.
Results: While 37.4% of our patients relapsed of ITP with subsequent platelet count drop sometime during first six months of discontinuation of eltrombopag, a total of 74 patients (14.6%) were able to achieve SDOE.
The median age of SDOE patients was 62 range, 47-79 years. There were 47 women and 27 men. According to the standard definition, patients were allocated to newly diagnosed (n=17), persistent (n=15) and chronic (n=42) ITP groups. The median time from diagnosis to eltrombopag initiation was 31 range, 4-104 months. The median number of previous therapies was 2 range, 1-2, including splenectomy (14%), rituximab (18%) and romiplostim (12%). As expected, all patients but 1 achieved a complete response (platelet count ≥100 x 109/L) prior to eltrombopag discontinuation The median duration of eltrombopag treatment was 7 range, 2-19 months. Reasons for eltrombopag discontinuation were: persistent response despite a reduction in dose over time (n=43), platelet count >400x109/L (n=16), aspartate aminotransferase elevation (n=5), diarrhea (n=4), thrombosis (n=3), patient's request (n=2) and other reasons (n=1).
Analysis of these SDOE discontinued patients show that with a median follow-up of 55 range, 29-79 months, 38 patients (51.3%) maintained treatment-free response 36 months after stopping eltrombopag with no need of additional ITP therapies (median time of eltrombopag discontinuation was 70 range, 50-77 months).This condition is what we define now as LTDOE. Nevertheless, 36 patients relapsed beyond 6 months but before 36 months of eltrombopag discontinuation (median time of eltrombopag discontinuation was 10 range,7 -22 months).
Characteristics of LTDOE population were a median time since ITP diagnosis of 32 range, 5-88 months with 15/38 patients having ITP <1 year. 9 patients (24%) were male and their median age was 50 range, 37-64 years. They had received a median of only two previous treatment lines range: 1-2 lines. The median platelet count before starting eltrombopag was 19 x 109/L range, 8-40. Meanwhile, platelet count before eltrombopag stop was 218 x 109/L range, 123-356.
The main characteristics (age, gender, duration of ITP, prior ITP lines, platelet count before starting eltrombopag, duration of eltrombopag treatment, and platelet count before eltrombopag withdrawal) of the 38 patients with LTDOE were compared with those of the SDOE cohort who did not achieve a LTDOE. Unfortunately, no predictive factors of LTDOE could be identified.
Conclusion: Durable platelet response following eltrombopag cessation may be observed in only 15% of primary ITP patients treated with this drug. On the contrary, half of patients who achieve a sustained response after eltrombopag withdrawal will get a long term discontinuation. However, we are lacking predictor factors for successful and long-term discontinuation of eltrombopag in primary ITP.
