ABSTRACT
Background: The SARS-CoV- 2 pandemic has led to changes in the way we manage autoimmune disease such as immune thrombocytopenia (ITP). Immunosuppression is a risk factor for severe COVID-19 and also leads to reduced vaccine responses. Medical therapy for ITP is broadly divided into immunosuppressive or that which stimulates megakaryopoeisis. Aim(s): To assess changes in medical therapy for ITP during the SARS-CoV- 2 pandemic using data from the UK adult ITP registry Methods: The UK registry of primary adult ITP (https://www.qmul. ac.uk/itpre gistr y/), one of the largest internationally, produces annual treatment reports on therapy use, trends and to identify cohorts for study. We reviewed data from annual reports to assess treatment changes. Result(s): At the time of analysis, there were 4503 patients in the registry: 224 diagnosed with ITP in 2019, 105 in 2020 and 97 in 2021 (median age 57y, 59y and 55y respectively). Table 1 shows changes in treatment 2019-2021. Most patients still received steroids as part of the treatment for ITP acutely. IVIG use remained static between 2019 and 2021. For diagnoses made between 2019 and 2021 all patients received at least 1 treatment. Immunosuppressive therapy use reduced from pre-2019 levels (data not tabulated) where almost 23% patients received rituximab and 18% MMF to 0% and 3% respectively by 2021. Use of TPO-RA increased, from 33% in 2019 to 43% in 2021. Median time to starting TPO-RA was 3.76 months (IQR 1.317,9.225) in 2019 reducing to 0.985 months (IQR 0.58,1.465) in 2021. Platelet response criteria will undergo analysis once additional data entry has taken place. Conclusion(s): Steroids continue to be used acutely for most ITP patients but TPO-RA are being used ahead of other immunosuppressive therapy in line with interim NHSE pandemic policy. Most patients entered received at least one line of treatment -likely reflecting those frequently attending sites to access healthcare.
ABSTRACT
Immune thrombocytopenia (ITP) is an acquired autoimmune disorder defined by a platelet count < 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. 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. 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 patients with ITP. Furthermore, data from subsets of patients will address (6) the impact of COVID-19 in patients with ITP;and (7) special issues affecting ITP in pregnancy. A steering committee of ITP expert physicians and patient advocacy group representatives are designing and will endorse the patient and physician surveys now nearing readiness after several meetings to determine the areas of greatest need of assessment. In addition, a control group will be included. Survey launch and data collection are scheduled to commence in early Q4 2020. Patients and physicians will complete similar online surveys. Both patient and physician surveys include a screener and sections of questions related to the specific objectives of I-WISh 2.0. The surveys include updates to key topics in I-WISh 1.0 (impact of fatigue, impact on daily life, treatment of ITP, emotional impact of ITP);validated patient-reported outcome tools to measure fatigue (MFIS-5), presence and severity of depression (PHQ-9), work-related burden (WPAI), and impact on quality of life (ILQI) tools;and questions related to COVID-19, telemedicine (remote patient monitoring), and pregnancy and ITP. Patients will be recruited to I-WISh 2.0 via treating physicians and patient advocacy groups, and will be included if they are ≥ 18 years of age, diagnosed with ITP, and agree to participate. Participating physicians will be required to be actively managing patients with ITP and have a minimum caseload of 3 ITP patients currently under their care;physicians must also have a primary specialty of hematology or hematology-oncology. Approval will be sought from an independent centralized Institutional Review Board. Data analysis will be primarily descriptive and correlative in nature. Breakdown by country and geographic areas will be included. A global sample is planned from 21 countries across 6 continents, with the aim of surveying more than 2000 patients and 600 physicians. I-WISh 2.0 will be the largest observational global survey ever conducted in ITP. If accepted, preliminary data are planned to be presented at the ASH meeting. I-WISh 2.0 will build on the strengths of I-WISh 1.0, which highlighted areas requir ng further assessment and will explore aspects of ITP of great interest that were neither conclusively addressed in the first survey nor well-studied in the past.
