Grainger J, Bussel J, Tarantino M, et al., 2023, A single-arm, long-term efficacy and safety study of subcutaneous romiplostim in children with immune thrombocytopenia., Blood Adv, Vol: 7, Pages: 396-405
Romiplostim is a thrombopoietin (TPO) receptor agonist approved for children and adults with immune thrombocytopenia (ITP) for ≥6 months, recommended as second-line treatment. This phase 3b, single-arm, multicenter study investigated long-term efficacy and safety of romiplostim in children ≥1 to <18 years old with ≥6 months' ITP duration and platelet counts ≤30 × 109/L. Children received weekly subcutaneous romiplostim (1 μg/kg titrated to 10 μg/kg) to maintain platelets within 50 to 200 × 109/L. A subset underwent bone marrow examinations. The primary end point was percentage of time with platelet response during the first 6 months' treatment (counts ≥50 × 109/L without rescue medication within the preceding 4 weeks). Overall, 203 patients (median age, 10.0 years) received ≥1 dose of romiplostim, median treatment duration was ∼3 years, and median average weekly dose was 6.9 μg/kg. Ninety-five (46.8%) discontinued (lack of efficacy, n = 43 [21.2%]). Platelet responses were achieved a median (interquartile range) of 50.0% (16.7%-83.3%) of the time during the first 6 months, increasing to 78.2% (26.7%-90.4%) during the overall 36-month treatment period. Eleven patients (5.4%) achieved sustained responses (consecutive counts ≥50 × 109/L without ITP medications for ≥24 weeks). Treatment-related adverse events (AEs) occurred in 56 patients (27.6%), with 8 (3.9%) experiencing serious treatment-related AEs; all of these led to discontinuation, including 4 cases of neutralizing antibodies (romiplostim, n = 3; TPO, n = 1). Bleeding occurred in 141 patients (69.5%), decreasing over time; grade ≥3 bleeding events occurred in 20 (9.9%). At year 2, eight of 63 evaluable patients (12.7%) had grade 2 reticulin. Long-term romiplostim resulted in sustained on-treatment platelet responses with an overall safety profile consistent with previous studies. This trial was registered at ww
Malik A, Sayed AA, Han P, et al., 2023, The role of CD8+ T cell clones in immune thrombocytopenia., Blood
Immune thrombocytopenia (ITP) is traditionally considered an antibody-mediated disease. However, a number of features suggest alternative mechanisms of platelet destruction. In this study, we use a multi-dimensional approach to explore the role of cytotoxic CD8+ T cells in ITP. We characterised patients with ITP and compared them to age-matched controls using immunophenotyping, next-generation sequencing of T cell receptor (TCR) genes, single-cell RNA sequencing, and functional T cell and platelet assays. We found that adults with chronic ITP have increased polyfunctional, terminally differentiated effector memory CD8+ T cells (CD45RA+CD62L-) expressing intracellular interferon-g, tumour necrosis factor-a, and Granzyme B defining them as TEMRA cells. These TEMRA cells expand when the platelet count falls and show no evidence of physiological exhaustion. Deep sequencing of the T cell receptor showed expanded T cell clones in patients with ITP. T cell clones persisted over many years, were more prominent in patients with refractory disease, and expanded when the platelet count was low. Combined single-cell RNA and TCR sequencing of CD8+ T cells confirmed that the expanded clones are TEMRA cells. Using in vitro model systems, we show that CD8+ T cells from patients with ITP form aggregates with autologous platelets, release interferon-g and trigger platelet activation and apoptosis through TCR-mediated release of cytotoxic granules. These findings of clonally expanded CD8+ T cells causing platelet activation and apoptosis provide an antibody-independent mechanism of platelet destruction, indicating that targeting specific T-cell clones could be a novel therapeutic approach for patients with refractory ITP.
Burnham KL, Maher AK, Jones EM, et al., 2022, Transcriptional reprogramming from innate immune functions to a pro-thrombotic signature by monocytes in COVID-19, Nature Communications, Vol: 13, Pages: 1-17, ISSN: 2041-1723
Although alterations in myeloid cells have been observed in COVID-19, the specific underlying mechanisms are not completely understood. Here, we examine the function of classical CD14+ monocytes in patients with mild and moderate COVID-19 during the acute phase of infection and in healthy individuals. Monocytes from COVID-19 patients display altered expression of cell surface receptors and a dysfunctional metabolic profile that distinguish them from healthy monocytes. Secondary pathogen sensing ex vivo leads to defects in pro-inflammatory cytokine and type-I IFN production in moderate COVID-19 cases, together with defects in glycolysis. COVID-19 monocytes switch their gene expression profile from canonical innate immune to pro-thrombotic signatures and are functionally pro-thrombotic, both at baseline and following ex vivo stimulation with SARS-CoV-2. Transcriptionally, COVID-19 monocytes are characterized by enrichment of pathways involved in hemostasis, immunothrombosis, platelet aggregation and other accessory pathways to platelet activation and clot formation. These results identify a potential mechanism by which monocyte dysfunction may contribute to COVID-19 pathology.
Robbins AJ, Che Bakri NA, Toke-Bjolgerud E, et al., 2022, The effect of TRV027 on coagulation in COVID 19: A pilot randomized, placebo-controlled controlled trial, British Journal of Clinical Pharmacology, ISSN: 0306-5251
COVID-19 causes significant thrombosis and coagulopathy, with elevated D-dimer a predictor of adverse outcome. The precise mechanism of this coagulopathy remains unclear, one hypothesis is that loss of Angiotensin Converting Enzyme 2 activity during viral endocytosis leads to pro-inflammatory angiotensin II accumulation, loss of angiotensin-1-7 and subsequent vascular endothelial activation. We undertook a double blind randomised, placebo controlled experimental medicine study to assess the effect of TRV027, a synthetic angiotensin-1-7 analogue on D-dimer in 30 patients admitted to hospital with COVID-19 (REC ref. 20/HRA/3414), Clinical Trial No. NCT04419610.The study showed a similar rate of adverse events in TRV027 and control groups. There was a numerical decrease in D-dimer in the TRV027 group and increase in D-dimer in the placebo group, however, this did not reach statistical significance (p=0.15). A Bayesian analysis demonstrated there was a 92% probability that this change represented a true drug effect.

Cook L, O'dell G, Vourvou E, et al., 2022, Third primary SARS-CoV-2 mRNA vaccines enhance antibody responses in most patients with haematological malignancies, Nature Communications, Vol: 13, Pages: 1-6, ISSN: 2041-1723
SARS-CoV-2 infection, and resulting disease, COVID-19, has a high mortality amongst patients with haematological malignancies. Global vaccine rollouts have reduced hospitalisations and deaths, but vaccine efficacy in patients with haematological malignancies is known to be reduced. The UK-strategyoffered a third, mRNA-based, vaccine as an extension to the primary course in these patients. The MARCH database is a retrospective observational study of serological responses in patients with blood disorders. Here we present data on 381 patients with haematological malignancies. By comparison with healthy controls, we report suboptimal responses following two primary vaccines, with significantly enhanced responses following the third primary dose. These responses however are heterogeneous and determined by haematological malignancy sub-type and therapy. We identify a group of patients with continued sub-optimal vaccine responses who may benefit from additional doses, prophylactic extended half-life neutralising monoclonal therapies (nMAB) or prompt nMAB treatment in the event of SARS-CoV-2 infection.

Joyce KE, Onabanjo E, Brownlow S, et al., 2022, Whole genome sequences discriminate hereditary hemorrhagic telangiectasia phenotypes by non-HHT deleterious DNA variants, Blood Advances, Vol: 6, Pages: 3956-3969, ISSN: 2473-9529
The abnormal vascular structures of hereditary hemorrhagic telangiectasia (HHT) often cause severe anemia due to recurrent hemorrhage, but HHT-causal genes do not predict the severity of hematological complications. We tested for chance inheritance and clinical associations of rare deleterious variants where loss-of-function causes bleeding or hemolytic disorders in the general population. In double-blinded analyses, all 104 HHT patients from a single reference centre recruited to the 100,000 Genomes Project were categorised on new MALO (more/as-expected/less/opposite) sub-phenotype severity scales, and whole genome sequencing data tested for high impact variants in 75 HHT-independent genes encoding coagulation factors, platelet, hemoglobin, erythrocyte enzyme and erythrocyte membrane constituents. Rare variants (all GnomAD allele frequencies <0.003) were identified in 56 (75%) of these 75 HHT-unrelated genes, and in 38/104 (36.5%) of the HHT patients. Likely deleteriousness assignments by Combined Annotation Dependent Depletion (CADD) scores >15 were supported by gene-level mutation significance cutoff (MSC) scores. CADD>15 variants were found for 1 in 10 patients within platelet genes; 1 in 8 within coagulation genes; and 1 in 4 within erythrocyte hemolytic genes. In blinded analyses, patients with greater hemorrhagic severity that had been attributed solely to HHT vessels had more CADD-deleterious variants in platelet (Spearman ρ=0.25, p=0.008) and coagulation (Spearman ρ=0.21, p=0.024) genes. However, the HHT cohort had 60% fewer deleterious variants in platelet and coagulation genes than expected (Mann Whitney p=0.021). In conclusion, HHT patients commonly have rare variants in genes of relevance to their phenotype, offering new therapeutic targets and opportunities for informed, personalised medicine strategies.

Cooper N, Morrison MA, Vladescu C, et al., 2020, Identification of occult cerebral microbleeds in adults with immune thrombocytopenia, Blood, Vol: 136, Pages: 2875-2880, ISSN: 0006-4971
Management of symptoms and prevention of life-threatening hemorrhage in immune thrombocytopenia (ITP) must be balanced against adverse effects of therapies. Because current treatment guidelines based on platelet count are confounded by variable bleeding phenotypes, there is a need to identify new objective markers of disease severity for treatment stratification. In this cross-sectional prospective study of 49 patients with ITP and nadir platelet counts <30 × 109/L and 18 aged-matched healthy controls, we used susceptibility-weighted magnetic resonance imaging to detect cerebral microbleeds (CMBs) as a marker of occult hemorrhage. CMBs were detected using a semiautomated method and correlated with clinical metadata using multivariate regression analysis. No CMBs were detected in health controls. In contrast, lobar CMBs were identified in 43% (21 of 49) of patients with ITP; prevalence increased with decreasing nadir platelet count (0/4, ≥15 × 109/L; 2/9, 10-14 × 109/L; 4/11, 5-9 × 109/L; 15/25 <5 × 109/L) and was associated with longer disease duration (P = 7 × 10−6), lower nadir platelet count (P = .005), lower platelet count at time of neuroimaging (P = .029), and higher organ bleeding scores (P = .028). Mucosal and skin bleeding scores, number of previous treatments, age, and sex were not associated with CMBs. Occult cerebral microhemorrhage is common in patients with moderate to severe ITP. Strong associations with ITP duration may reflect CMB accrual over time or more refractory disease. Further longitudinal studies in children and adults will allow greater understanding of the natural history and clinical and prognostic significance of CMBs.

<jats:p>Immune thrombocytopenia (ITP) is an acquired autoimmune disorder defined by a platelet count &lt; 100 × 109/L without explanation, and an increased risk of bleeding. ITP itself as well as its treatments have multifaceted, often poorly understood impacts on patients' quality of life (QoL). These effects include impact on activities of daily living, emotional health, energy, ability to think well and clearly, and productivity in the workplace. There are limited data on which individual aspects of ITP are perceived both by patients and physicians as having the greatest impact on QoL. Understanding patients' perspectives is vital to optimize their QoL by specifying particular areas in need of therapy.</jats:p> <jats:p>I-WISh 1.0 was an exploratory, cross-sectional survey in which 1507 patients with ITP and 472 physicians across 13 countries completed separate, but related, online surveys that included assessments of ITP signs and symptoms, impact of symptoms, and patient-physician relationships. These findings have been presented at previous ASH and EHA congresses, and manuscripts are currently in preparation. However, although I-WISh 1.0 provided considerable insights into unexplored facets of the effects of ITP, an all-too-large number of gaps in understanding still remain. In response to this, I-WISh 2.0 is currently being developed.</jats:p> <jats:p>The objectives of the I-WISh 2.0 patient and physician cross-sectional surveys include: (1) to further explore the burden of fatigue and how it affects patients' lives, including what makes it better or worse; (2) to assess the emotional impact of living with chronic ITP, especially in relation to depression; (3) to assess how treatments for ITP can impact activities of daily living (positively and negatively); (4) to further relate effects of treatment to patients' QoL; and (5) to explore how telemedicine affects healthcare delivery for pati

Primary immunodeficiency (PID) is characterized by recurrent and often life-threatening infections, autoimmunity and cancer, and it poses major diagnostic and therapeutic challenges. Although the most severe forms of PID are identified in early childhood, most patients present in adulthood, typically with no apparent family history and a variable clinical phenotype of widespread immune dysregulation: about 25% of patients have autoimmune disease, allergy is prevalent and up to 10% develop lymphoid malignancies1-3. Consequently, in sporadic (or non-familial) PID genetic diagnosis is difficult and the role of genetics is not well defined. Here we address these challenges by performing whole-genome sequencing in a large PID cohort of 1,318 participants. An analysis of the coding regions of the genome in 886 index cases of PID found that disease-causing mutations in known genes that are implicated in monogenic PID occurred in 10.3% of these patients, and a Bayesian approach (BeviMed4) identified multiple new candidate PID-associated genes, including IVNS1ABP. We also examined the noncoding genome, and found deletions in regulatory regions that contribute to disease causation. In addition, we used a genome-wide association study to identify loci that are associated with PID, and found evidence for the colocalization of-and interplay between-novel high-penetrance monogenic variants and common variants (at the PTPN2 and SOCS1 loci). This begins to explain the contribution of common variants to the variable penetrance and phenotypic complexity that are observed in PID. Thus, using a cohort-based whole-genome-sequencing approach in the diagnosis of PID can increase diagnostic yield and further our understanding of the key pathways that influence immune responsiveness in humans.

These updated EBMT guidelines review the clinical evidence, registry activity and mechanisms of action of haematopoietic stem cell transplantation (HSCT) in multiple sclerosis (MS) and other immune-mediated neurological diseases and provide recommendations for patient selection, transplant technique, follow-up and future development. The major focus is on autologous HSCT (aHSCT), used in MS for over two decades and currently the fastest growing indication for this treatment in Europe, with increasing evidence to support its use in highly active relapsing remitting MS failing to respond to disease modifying therapies. aHSCT may have a potential role in the treatment of the progressive forms of MS with a significant inflammatory component and other immune-mediated neurological diseases, including chronic inflammatory demyelinating polyneuropathy, neuromyelitis optica, myasthenia gravis and stiff person syndrome. Allogeneic HSCT should only be considered where potential risks are justified. Compared with other immunomodulatory treatments, HSCT is associated with greater short-term risks and requires close interspeciality collaboration between transplant physicians and neurologists with a special interest in these neurological conditions before, during and after treatment in accredited HSCT centres. Other experimental cell therapies are developmental for these diseases and patients should only be treated on clinical trials.

Downes K, Megy K, Duarte D, et al., 2019, Diagnostic high-throughput sequencing of 2396 patients with bleeding, thrombotic, and platelet disorders, Blood, Vol: 134, Pages: 2082-2091, ISSN: 1528-0020
A targeted high-throughput sequencing (HTS) panel test for clinical diagnostics requires careful consideration of the inclusion of appropriate diagnostic-grade genes, the ability to detect multiple types of genomic variation with high levels of analytic sensitivity and reproducibility, and variant interpretation by a multi-disciplinary team (MDT) in the context of the clinical phenotype. We have sequenced 2,396 index patients using the ThromboGenomics HTS panel test of diagnostic-grade genes known to harbour variants associated with rare bleeding, thrombotic or platelet disorders (BTPD). The molecular diagnostic rate was determined by the clinical phenotype, with an overall rate of 49.2% for all thrombotic, coagulation, platelet count and function disorder patients and a rate of 3.2% for patients with unexplained bleeding disorders characterized by normal hemostasis test results. The MDT classified 745 unique variants, including copy number and intronic variants, as Pathogenic, Likely Pathogenic or Variants of Uncertain Significance. Half (50.9%) of these variants are novel and 41 unique variants were identified in 7 genes recently found to be implicated in BTPD. Inspection of canonical hemostasis pathways identified 29 patients with evidence of oligogenic inheritance. A molecular diagnosis has been reported for 894 index patients providing evidence that introducing an HTS genetic test is a valuable addition to laboratory diagnostics in patients with a high likelihood of having an inherited BTPD.
