The Outcomes and Adverse Drug Patterns of Immunomodulators and Thrombopoietin Receptor Agonists in Primary Immune Thrombocytopenia Egyptian Patients with Hemorrhage Comorbidity. Pharmaceuticals (Basel) 2023; 16:868. [PMID: 37375815 DOI: 10.3390/ph16060868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 05/26/2023] [Accepted: 05/29/2023] [Indexed: 06/29/2023] Open
Abstract
Immune thrombocytopenia (ITP) treatment has evolved recently. However, none of the treatments have only benefits without drawbacks. This study aimed to compare the clinical outcomes and adverse drug patterns of Eltrombopag, Romiplostim, Prednisolone + Azathioprine, High Dose-dexamethasone (HD-DXM) (control group), and Rituximab in primary ITP Egyptian patients. All patients were initiated with corticosteroids, HD-DXM, as a first-line treatment for the first month immediately following diagnosis. Four hundred sixty-seven ITP patients were randomly assigned to five groups. The outcome measures were judged at baseline, at the end of treatment (6 months), and after an additional 6-month free treatment period. The follow-up period for which relapse is noted was 6 months after the end of treatment. Eltrombopag and Romiplostim resulted in a significantly higher incidence of sustained response than Rituximab, HD-DXM, and Prednisolone + Azathioprine (55.2% and 50.6% vs. 29.2%, 29.1%, and 18%, respectively; p-value < 0.001). More patients on immunomodulators (Prednisolone+ Azathioprine, HD-DXM, and Rituximab) relapsed than those on Romiplostim and Eltrombopag (81.9%, 70.8%, and 70.7% vs. 49.3%, and 44.7%, respectively; p-value < 0.01). We also describe 23 reports of pulmonary hypertension with Prednisolone+ Azathioprine and 13 reports with HD-DXM. The thrombotic events occurred in 16.6% and 13% of patients who received Eltrombopag and Romiplostim treatment, respectively. Most patients had at least one or two risk factors (92.8% of cases). Corticosteroids are effective first-line therapy in primary ITP patients. However, relapse is frequent. Eltrombopag and Romiplostim are safer and more effective than Prednisolone, HD-DXM, and Rituximab. They might be reasonable beneficial options after a one-month HD-DXM regimen.

Abstract
Primary immune thrombocytopenia (ITP) is an acquired blood disorder that causes a reduction in circulating platelets with the potential for bleeding. The incidence of ITP is slightly higher in adults and affects more women than men until 60 years, when males are more affected. Despite advances in basic science, primary ITP remains a diagnosis of exclusion. The disease is heterogeneous in its clinical behavior and response to treatment. This reflects the complex underlying pathophysiology, which remains ill-understood. Platelet destruction plays a role in thrombocytopenia, but underproduction is also a major contributing factor. Active ITP is a proinflammatory autoimmune disease involving abnormalities within the T and B regulatory cell compartments, along with several other immunological abnormalities. Over the last several years, there has been a shift from using immunosuppressive therapies for ITP towards approved treatments, such as thrombopoietin receptor agonists. The recent COVID-19 pandemic has hastened this management shift, with thrombopoietin receptor agonists becoming the predominant second-line treatment. A greater understanding of the underlying mechanisms has led to the development of several targeted therapies, some of which have been approved, with others still undergoing clinical development. Here we outline our view of the disease, including our opinion about the major diagnostic and therapeutic challenges. We also discuss our management of adult ITP and our placement of the various available therapies.

Abstract
Background and Objectives: TPO-RAs (romiplostim/eltrombopag/avatrombopag) have broadly demonstrated high efficacy rates (59-88%), durable responses (up to three years) and a satisfactory safety profile in clinical trials. The effect of TPO-RAs is classically considered to be transient because platelet numbers usually dropped rapidly to baseline unless therapy was maintained. However, several groups have reported the possibility of successfully discontinuing TPO-RAs in some patients without further need for concomitant treatments. This concept is usually referred as sustained remission off-treatment (SROT). Materials and Methods: Unfortunately, we still lack predictors of the response to discontinuation even after the numerous biological, clinical and in vitro studies performed to study this phenomenon. The frequency of successful discontinuation is matter of controversy, although a percentage in the range of 25-40% may probably be considered a consensus. Here, we describe all major routine clinical practice studies and reviews that report the current position on this topic and compare them with our own results in Burgos. Results: We report our Burgos ten-step eltrombopag tapering scheme with which we have achieved an elevated percentage rate of success (70.3%) in discontinuing treatment. Conclusions: We hope this protocol may help successfully taper and discontinue TPO-RAs in daily clinical practice.

Abstract
Patients with cirrhosis frequently require admission to the intensive care unit as complications arise in the course of their disease. These admissions are associated with high short- and long-term morbidity and mortality. Thus, understanding and characterizing complications and unique needs of patients with cirrhosis and acute-on-chronic liver failure helps providers identify appropriate level of care and evidence-based treatments. While there is no widely accepted critical care admission criteria for patients with cirrhosis, the presence of organ failure and primary or nosocomial infections are associated with particularly high in-hospital mortality. Optimal management of patients with cirrhosis in the critical care setting requires a system-based approach that acknowledges deviations from canonical pathophysiology. In this review, we discuss appropriate considerations and evidence-based practices for the general care of patients with cirrhosis and critical illness.

Abstract
ABSTRACT The oral thrombopoietin receptor agonist eltrombopag has some side effects. One of them is related to bilirubin metabolism. Two patients with neuroblastoma in remission underwent stem cell transplantation with the Busulfan-melphalan regimen. Eltrombopag was started because of platelet engraftment failure. Indirect hyperbilirubinemia was detected after eltrombopag treatment. Laboratory and radiological investigations were all normal. The drugs and their side effects they used were examined. After eltombopag cutting, bilirubin levels of them returned to normal. These cases are presented to emphasize that eltrombopag can cause liver toxicity with hypertransaminesemia and hyperbilirubinemia. Drug side effects should be considered in the differential diagnosis of the patients. The significance of this case is that testing for serum aminotransferase and bilirubin levels should be monitored before and after eltrombopag use.

Abstract
For many decades immune thrombocytopenia (ITP) was managed using therapies which had not undergone randomised clinical trials and included corticosteroids, immune suppression or splenectomy. These older therapies are associated with an increase in morbidity and mortality. These empirical therapies have variable efficacy and well-described side effects for many patients with minimal benefit to the patient. Over the past 10 years there has been a shift away from immune suppression and non-evidence-based therapies towards using treatments with reduced or no immune suppression with an increasing reliance on the recently developed and approved thrombopoietin receptor agonists. The recent COVID-19 pandemic has made it more urgent that we develop non-immune suppressive strategies for ITP. In this commentary we describe our proposal for a contemporary approach to the management of ITP in adults that is based on our hospital practices and published guidelines.

Abstract
BACKGROUND Eltrombopag is an orally administered thrombopoietin receptor agonist linked to a heightened risk of treatment-related thromboembolism. Both venous and arterial thromboses have been documented in the medical literature.
CASE SUMMARY In the absence of nephropathy, a 48-year-old patient receiving eltrombopag for immune thrombocytopenia (ITP) developed renal vein thrombosis and pulmonary embolism. The renal vein thrombus spontaneously resolved during subsequent anticoagulant treatment, restoring venous circulation.
CONCLUSION A rapid upsurge in platelets, rather than their absolute number, may trigger thrombotic events in this setting. For patients at high thrombotic risk, individualized eltrombopag dosing and vigilance in platelet monitoring are perhaps needed during treatment of ITP.

Abstract
Immune thrombocytopenia (ITP) is an autoimmune disorder in which a combination of defective platelet production and enhanced clearance leads to thrombocytopenia. The primary aim for therapy in patients with this condition is the prevention of bleeding. However, more recently, increased rates of venous and arterial thrombotic events have been reported in ITP, even in the context of marked thrombocytopenia. In this review we discuss the epidemiology, aetiology and management of thrombotic events in these patients. We consider the impact of ITP therapies on the increased thrombotic risk, in particular the use of thrombopoietin-receptor agonists (TPO-RAs), as well as factors inherent to ITP itself. We also discuss the limited evidence available to guide clinicians in the treatment of these complex cases.

Abstract
Autoimmune pancreatitis is a rare, distinct and increasingly recognized form of chronic inflammatory pancreatic disease secondary to an underlying autoimmune mechanism. We report on a 14-year-old boy who developed autoimmune pancreatitis, while he was under treatment with eltrombopag for chronic immune thrombocytopenia. Therapy with corticosteroids resulted in complete remission of both. This is the first report on the co-occurrence of autoimmune pancreatitis and chronic immune thrombocytopenia in childhood, and clinicians should be aware of this rare association, because early diagnosis and therapy of autoimmune pancreatitis may prevent severe complications.

Abstract
Staphylococcus epidermidis is a common cause of nosocomial infections, and readily adheres to medical apparatus to form biofilms consisting of highly resistant persister cells. Owing to the refractory infections caused by S. epidermidis biofilms and persisters in immunosuppressed patients, it is crucial to develop new antimicrobials. In the present study, we analyzed the antimicrobial effects of the thrombopoietin receptor agonist eltrombopag (EP) against S. epidermidis planktonic cells, biofilms, and persister cells. EP was significantly toxic to S. epidermidis with the minimal inhibitory concentration of 8 μg/ml, and effectively inhibited the biofilms and persisters in a strain-dependent manner. In addition, EP was only mildly toxic to mammalian cells after 12 to 24 h treatment. It also partially synergized with vancomycin against S. epidermidis, which enhanced its antimicrobial effects and reduced its toxicity to mammalian cells. Taken together, EP is a potential antibiotic for treating refractory infections caused by S. epidermidis.

Abstract
Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by platelet count less than 100×109/L and an increased risk of bleeding. The risk of bleeding increases in proportion with the degree of thrombocytopenia. Although several medications are used for primary thrombocytopenia treatment, refractoriness remains a concern. Romiplostim and eltrombopag, two relatively new drugs, have been shown to be successful in ITP treatment after standard treatment failure. The current guidelines recommend their use as a second-line treatment. In this article, we have tried to compare which of these two medications is the best option considering clinical effectiveness, cost-effectiveness, adverse effects, and the possibility of switching between them in case of ineffectiveness. The studies used in this article were found in the PubMed database. All the studies are limited to adults. Based on these studies, both medications seem to be a largely effective, safe option. Romiplostim appears to have slightly fewer adverse effects and higher costs. Switching between thrombopoietin receptor agonists (TRAs) is a successful way to overcome adverse effects and inadequacy according to the currently available literature. We believe that more detailed studies are needed to determine which of these drugs should be considered the first choice, to report long term efficacy and adverse effects, and to determine if treatment guidelines can change regarding the use of TRAs as first-line treatment.

Abstract
Aim: Eltrombopag and romiplostim are US FDA approved for treatment of immune thrombocytopenia in patients with insufficient response to other treatments. Clinical or real-world data comparing outcomes of the two drugs are limited. Methods: This retrospective cross-sectional study sought information on bleeding-related episodes (BREs), adverse events (AEs) and other outcomes of eltrombopag or romiplostim treatment in immune thrombocytopenia. Results: Patients receiving eltrombopag experienced significantly reduced BREs, severe BREs, rescue medication use and platelet transfusions. Diarrhea and headache were significantly less frequent in patients receiving eltrombopag; other AEs occurred equally in both groups. Conclusion: There may be a potential advantage for the use of eltrombopag versus romiplostim in the practice settings studied, based on rates of BREs and AEs and rescue medication utilization.

Abstract
Introduction: Immune thrombocytopenia (ITP) is an autoimmune disease. Even though there are many treatments available, some patients remain resistant to multiple treatments. Therefore, it is very important to develop new treatment options. Areas covered: Here, the authors summarize several current and emerging treatments developed for ITP in recent years. They include a summary of their mechanisms of action and clinical trial results. Expert opinion: At present, the first-line treatment of ITP is glucocorticoid and intravenous immunoglobulin (IVIg). Other traditional therapies include splenectomy, thrombopoietin (TPO), rituximab and other immunosuppressive agents. The several emerging treatments developed recently for ITP may change the treatment pattern in the future.

Abstract
BACKGROUND There is evidence that the thrombopoietin-receptor agonists romiplostim and eltrombopag may have different therapeutic values and adverse reaction profiles. Here we present new data and provide a review of all studies dealing with switching between these two drugs. MATERIALS AND METHODS A total of 89 patients (38 males and 51 females, aged between 14-87 years) were treated with eltrombopag and/or romiplostim between 2007 and 2016 at our institution. Eltrombopag was switched to romiplostim or vice versa in 32 patients. In addition, all published data concerning patients treated sequentially with different thrombopoietin-receptor agonists were identified via a computer-assisted search and summarised in this article. RESULTS Thirty-two of 89 patients treated with a thrombopoietin-receptor agonist in our institution were given both eltrombopag and romiplostim sequentially. Therapy was switched to the alternate thrombopoietin-receptor agonist 36 times, due to inefficacy (n=21), adverse reactions (n=14), and a patient's preference (n=1). In addition, data from 126 patients who have been treated with both agonists have been published by other groups. In total eltrombopag was replaced by romiplostim in 56 cases due to poor or no response or to adverse reactions. Forty-five patients responded to treatment with romiplostim, 11 patients shared cross-resistance and nine had adverse reactions to romiplostim. In contrast, romiplostim was replaced by eltrombopag in 106 cases. Seventy-eight patients responded to eltrombopag, 27 shared cross-resistance and 19 had adverse reactions to eltrombopag. DISCUSSION Eltrombopag and romiplostim often share bidirectional cross-resistance and/or adverse reactions. Both drugs appear to cause more adverse reactions than have been previously reported.

Abstract
INTRODUCTION Eltrombopag and romiplostim are thrombopoietin receptor agonists (TPO-RAs) marketed for immune thrombocytopenia (ITP). Thrombotic events have been reported with both drugs. This study was aimed at assessing whether there is a signal for differential risks of thrombosis between these two TPO-RAs. METHODS We carried out a disproportionality analysis in the World Health Organization global individual case safety report (ICSR) database (VigiBase(®)). We selected all ICSRs with exposure to a TPO-RA between January 2011 and December 2014. We searched for exposures to eltrombopag or romiplostim in thrombosis reports as compared with other ICSRs, and we calculated adjusted reporting odds ratios (aRORs). RESULTS We identified 5850 ICSRs, including 764 cases of thrombosis. In multivariate analyses, there was a signal for an increased risk of thrombosis (venous or arterial; aROR 1.72, 95 % confidence interval [CI] 1.47-2.02), venous thrombosis (aROR 1.88, 95 % CI 1.53-2.31), arterial thrombosis (aROR 1.54, 95 % CI 1.18-2.00), ischaemic stroke (aROR 1.65, 95 % CI 1.13-2.42) and myocardial infarction (aROR 1.50, 95 % CI 1.05-2.13) with eltrombopag as compared with romiplostim. Restriction to ICSRs reported by physicians led to similar results. However, worldwide dispensing data for romiplostim and eltrombopag were not accessible, so the rates of thrombosis with both drugs were not normalized by the daily defined doses and the generalizability of the results is limited. CONCLUSION This study suggests the presence of a signal for an increased risk of thrombosis with eltrombopag compared with romiplostim. These results must be confirmed and quantified by large aetiological pharmacoepidemiological studies.

Abstract
Immune thrombocytopenia (ITP) represents the epitome of acquired bleeding diseases for the hematologist. Stemming from the interest for the safety of thrombopoietin-receptor agonists (TPO-ra) romiplostim and eltrombopag, recent data have investigated if thrombotic risk is also increased in this disorder. In patients not treated with TPO-ra, a slightly higher risk of venous thrombosis (VTE) is consistently found in ITP, but not to a rate demanding special attention in the generality of cases. No significant increase of arterial thrombosis (AT) is apparent. However, age, splenectomy, and personal risk factors may put some ITP patient to a particularly higher risk of venous and arterial thrombosis (three to four times higher than the average subject). Patients exposed to TPO-ra present indirect evidence of a much higher risk of both AT and VTE. Unfortunately, no matched control population is available and the prospective and registrative nature of these studies may have emphasized the incidence of thrombosis, which was recorded as adverse event. The clinician should be able to individualize the best treatment for the patient, taking also into account the thrombotic risk, limiting active treatment of ITP to those patients really at risk of bleeding.
