Abstract

Corticosteroids (CTCs) are the first-line treatment to manage immune thrombocytopenia (ITP). Prolonged immunosuppression is associated with adverse events, especially infection and loss of bone mineral density. Guidelines recommend avoiding the use of prednisone/methylprednisolone and dexamethasone >6-8 weeks and >3 cycles, respectively. Prophylaxis is recommended in patients who undergo long CTC exposure. We analyzed if recommendations regarding CTC use are followed by practitioners experienced in ITP management after implementation of national guidelines. A nationwide, retrospective, observational study was performed by the Spanish ITP Group. Two-hundred and forty-seven ITP treatments with =12 month post-treatment follow-up were reported. CTCs were given as first-line therapy in 200/247 (81.0%) cases. Prednisone/methylprednisolone and dexamethasone were administered in 161 and 84 cases, respectively. The median (interquartile range) duration of prednisone/methylprednisolone first-line treatment was 64 (43-83) and 69 (39-144) days in newly-diagnosed (n=102) and chronic (n=32) ITP patients, respectively. Dexamethasone treatment lasted =4 cycles in 15/84 (17.9%) cases. Prophylaxis against herpes simplex virus/herpes zoster virus, Pneumocystis carinii and osteopenia was administered before/during CTC treatment to 1/187 (0.5%), 16/140 (11.4%) and 10/37 (27.0%) eligible patients, respectively. In this representative cohort, management of CTCs is far from compliance with recommendations. Actions should be taken to address this shortcoming.

Introduction

Although new therapies have become available to manage immune thrombocytopenia (ITP) [1], corticosteroids (CTCs) remain the first-line of treatment [2-4]. However, the prolonged use of CTCs is associated with toxicity. More than 95% of treated ITP patients have reported adverse events (AEs) in survey studies [5]. There is consensus that the duration of this therapy has to be tightly controlled [2-4]. Prolonged immunosuppression places patients at a significant risk of severe conditions such as infection or ischemic events [6-8], and complications such as hyperglycemia or osteoporosis [9]. The risk is higher in elderly patients [8,10,11].

Safety of CTC therapy relies on two cornerstones: drug burden, associated with dose and therapy duration, and prophylaxis to prevent opportunistic infections and loss of bone mineral density. Guidelines regarding duration and dosage of treatments with prednisone, methylprednisolone or dexamethasone have long been available, and have not changed notably with successive updating [2-4,12-14]. Prophylaxis is recommended in long-term CTC treatment [15-17], although well-defined eligible patients and specific actions have only recently been included in treatment guides [2]. The Spanish ITP Group (GEPTI) of the Spanish Society of Hematology and Hemotherapy (SEHH) brings together clinicians with experience in ITP management. The GEPTI Registry is open to Spanish hematology practitioners to include patients [2,14,18-20]. Our objective was to assess if CTC-based therapies are properly and safely administered to ITP patients in a nationwide scenario.

Methods

Patients and Design

A nationwide, retrospective, multicenter, observational study was conducted. Those ITP patients who were treated with CTCs between January-2020 to April-2024 and had a minimum 12-month followup were included. All CTC-based treatments that were administered during this period were reported, regardless of whether more than one of them could have been administered to the same patient. Provided that enough information about dosing, prophylaxis and outcomes was available, treatments administered before the recruitment period were included. Inclusion criteria were age >18 years, and use of CTC treatment to manage an ITP, diagnosed according to updated ITP international consensus criteria [4]. Patients were monitored during a 12-month post-treatment follow-up period. Treatment response, relapse, toxicities and AEs were reported. The exclusion criterion was the simultaneous presence of thrombocytopenia-predisposing conditions other than ITP. The study (code 1104-N-23) was approved by the Medical Research Ethics Committees of all hospitals. All patients signed the Informed Consent Form, and their data were anonymized. The study was conducted in accordance with the Declaration of Helsinki.

Assessments

Type of CTC Treatment: CTC type, dose and duration were reported. Treatment duration in patients >75 years was also calculated [21]. In chronic ITP patients, CTC was considered as first-line treatment again when they suffered a relapse =2 years after the end of first-line treatment.

Effectiveness: Effectiveness was assessed according to the response criteria defined by the updated ITP international consensus report (Table S1) [2-4,22].

Prophylaxis: Compliance with prophylaxis according to the guidelines recently detailed by GEPTI investigators was analyzed [2]. The proportion of candidates who were administered prophylaxis against herpes simplex virus/herpes zoster virus (HSV/HZV), Pneumocystis carinii, hepatitis B virus (HBV) and/or osteopenia/ osteoporosis was calculated. The criteria to identify patients where prophylaxis would be recommended are outlined in Table S2.

Toxicities and AEs: Infections requiring hospitalization, ischemic events and bone fractures were considered as main AEs. Other toxicities were development/worsening of type 2 diabetes mellitus (T2DM), arterial hypertension, dyslipidemia, Cushing syndrome, myopathy and folliculitis.

Statistical Analysis

Discrete variables were summarized as numbers and percentages and continuous variables were described by median (interquartile range [IQR]). The chi-square test compared effectiveness and relapse among treatments. The Kruskal-Wallis test compared time to relapse among treatments. The Mann-Whitney U test compared duration of treatment according to subsequent development of infection.

Results

Baseline Features

Two-hundred and twelve ITP patients who had received treatment with CTCs between January-2020 and April-2024 were recruited (Figure 1). Seventy percent of patients had been newly diagnosed, and 59% were female. Thirty-six (17.0%) patients presented with another autoimmune disease, 26 of whom (72.2%) were female (Table 1).
