MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1153. [PMID: 39064581 PMCID: PMC11279052 DOI: 10.3390/medicina60071153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/10/2024] [Revised: 07/07/2024] [Accepted: 07/16/2024] [Indexed: 07/28/2024]
Abstract
Background and Objectives: Immune thrombocytopenia (ITP) is an autoimmune disease characterized by the autoantibody-mediated destruction of platelets. The treatment of ITP aims to maintain a sufficient platelet count to prevent bleeding. First-line treatment options include corticosteroids and intravenous immunoglobulin (IVIg), while second-line treatments include splenectomy, rituximab and other immunosuppressive agents, and thrombopoietin (TPO) receptor agonists. This study aims to discuss the treatment methods and results from 100 patients with ITP at the Muğla Training and Research Hospital through a pharmacological approach. Materials and Methods: Demographic characteristics, clinical findings, bone marrow aspiration and biopsy results, and treatments and treatment responses at the time of diagnosis of the 100 patients with ITP who were treated and followed up in the period 2015-2023 were evaluated retrospectively. Results: In the third month after treatment, the overall response percentage was 100% in patients who received steroids only and 88% in patients who received IVIg treatment alone or in combination with steroids (p > 0.05). The most preferred second-line treatments were splenectomy (41%), eltrombopag (26%), and rituximab (10%). Bone marrow biopsy was performed in 54% of patients, where 35.1% showed increased megakaryocytes, 44.4% adequate megakaryocytes, and 14.8% decreased megakaryocytes. It is noted that eltrombopag and rituximab, in particular, yield higher complete remission rates than immunosuppressive drugs. Conclusions: Considering the side effects of immunosuppressive medications, IVIg, splenectomy, and steroid therapy, the use of new agents such as eltrombopag, which are easily tolerated and have a lower risk of side effects, is expected to increase.

Int Immunopharmacol 2024; 131:111810. [PMID: 38492341 DOI: 10.1016/j.intimp.2024.111810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 02/27/2024] [Accepted: 03/04/2024] [Indexed: 03/18/2024]
Abstract
Immune thrombocytopenia (ITP) is an acquired immune disorder characterized by increased platelet destruction and reduced platelet (Plt) production. Hypoxia-inducible factor-1α (HIF-1α) have regulatory effects on Treg/Th17 axis balance and may represent relevant factors in the pathogenesis of ITP. Treg/Th17 ratio, serum levels and gene expression were investigated in new diagnosed ITP (NITP) and chronic ITP (CITP). The Treg/Th17 ratio obviously decreased in CITP (P = 0.001). The ratio of Treg/Th17 was correlated with the level of HIF-1α level both in mRNA (r = 0.49, P < 0.0001) and serum level (r = 0.50, P < 0.0001). However, none statistical upregulation of HIF-1α was observed in CITP. In vitro, There was significant polarization difference of Treg/Th17 axis (P = 0.042) and Foxp3-MFI/IL17-MFI (P = 0.0003) in hypoxic condition between NITP and CITP. These findings suggest that HIF-1α induced by hypoxia plays a crucial role in the chronicity of ITP by mediating the imbalance of the Treg/Th17 axis.

Abstract
There are not many publications that provide a holistic view of the management of primary and secondary ITP as a whole, reflecting the similarities and differences between the two. Given the lack of major clinical trials, we believe that comprehensive reviews are much needed to guide the diagnosis and treatment of ITP today. Therefore, our review addresses the contemporary diagnosis and treatment of ITP in adult patients. With respect to primary ITP we especially focus on establishing the management of ITP based on the different and successive lines of treatment. Life-threatening situations, "bridge therapy" to surgery or invasive procedures and refractory ITP are also comprehensively reviewed here. Secondary ITP is studied according to its pathogenesis by establishing three major differential groups: Immune Thrombocytopenia due to Central Defects, Immune Thrombocytopenia due to Blocked Differentiation and Immune Thrombocytopenia due to Defective Peripheral Immune Response. Here we provide an up-to-date snapshot of the current diagnosis and treatment of ITP, including a special interest in addressing rare causes of this disease in our daily clinical practice. The target population of this review is adult patients only and the target audience is medical professionals.

Abstract
The pathophysiology of immune thrombocytopenia (ITP) is complex and encompasses innate and adaptive immune responses, as well as megakaryocyte dysfunction. Rituximab is administered in relapsed cases and has the added benefit of inducing treatment-free remission in over 50% of patients. Nevertheless, the responses to this therapy are not long-lasting, and resistance development is frequent. B cells, T cells, and plasma cells play a role in developing resistance. To overcome this resistance, targeting these pathways through splenectomy and novel therapies that target FcγR pathway, FcRn, complement, B cells, plasma cells, and T cells can be useful. This review will summarize the pathogenetic mechanisms implicated in rituximab resistance and examine the potential therapeutic interventions to overcome it. This review will explore the efficacy of established therapies, as well as novel therapeutic approaches and agents currently in development.

Abstract
OBJECTIVE To conduct a meta-analysis assessing the efficacy and safety of cyclosporine-based combinations for primary immune thrombocytopenia (ITP). METHODS Randomized controlled clinical trials were collected by systematically searching databases (PubMed®, MEDLINE®, EMBASE, The Cochrane Library, China National Knowledge Infrastructure) from inception to June 2022. All studies included patients with ITP who received cyclosporine-based regimens. We performed comprehensive analyses of the overall response rate (ORR), complete response (CR) rate, partial response (PR) rate, relapse rate, platelet count, and adverse drug reaction (ADR) rate. RESULTS Seven studies (n = 418) were ultimately included. According to a fixed-effects model, cyclosporine-based combinations improved the ORR and CR rate and reduced the relapse rate. The ADR rate was not increased in the cyclosporine-based combination group. Cyclosporine-based regimens effectively increased the platelet count. Subgroup analysis illustrated that cyclosporine-based combinations were linked to higher ORRs in both children (odds ratio [OR] = 5.74, 95% confidence interval [CI] = 1.79-18.41) and adults (OR = 5.46, 95% CI = 2.48-12.02) and a higher CR rate in adults (OR = 2.97, 95% CI = 1.56-5.63). CONCLUSION Cyclosporine exhibited efficacy in the treatment of ITP without increasing the risk of ADRs.

Abstract
OBJECTIVES Cyclosporin is one of the therapeutic regimens for hemophagocytic lymphohistiocytosis (HLH); however, the optimal dosage of cyclosporine in children with HLH is unknown. It has been found that piperacillin-tazobactam affects the cyclosporine pharmacokinetic process in pediatric HLH patients. Thus, the purpose of the present study was to recommend cyclosporin dosage for pediatric HLH with and without piperacillin- tazobactam. METHODS A previously established cyclosporine population pharmacokinetic model for pediatric HLH patients has been used in this study to recommend optimal dosage based on Monte Carlo simulation. The pediatric HLH patients have been included in eight weight groups (5, 10, 20, 30, 40, 50, 60, 70 kg) for sixteen dosages (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 mg/kg), split into one dose or two doses. RESULTS The optimal cyclosporin dosages for children having HLH without piperacillin-tazobactam have been found to be 15, 13, 12, 11, 10, and 9 mg/kg, split into two doses for weights of 5-7, 7-10, 10-20, 20-28, 28-45, and 45-70 kg, respectively. For children with HLH, optimal cyclosporin dosages with piperacillin-tazobactam have been found to be 8 and 7 mg/kg, split into two doses for weights of 5-20 and 20-70 kg, respectively. CONCLUSION It is the first time that the cyclosporin dosage regimens for HLH in children have been developed based on Monte Carlo simulation, and the initial dosage optimizations of cyclosporine in pediatric HLH patients have been recommended.

Efficacy and safety of cyclosporine A treatment in autoimmune cytopenias: the experience of two Italian reference centers. Ther Adv Hematol 2022; 13:20406207221097780.

Abstract
Background: Immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA) show
good responses to frontline steroids. About two-third of cases relapse and
require second-line treatment, including rituximab, mainly effective in
AIHA, and thrombopoietin-receptor agonists (TPO-RAs) in ITP, while the use
of splenectomy progressively decreased due to concerns for
infectious/thrombotic complications. For those failing second line,
immunosuppressants may be considered. Objectives: The aim of this study was to evaluate the efficacy of cyclosporine treatment
in patients with ITP and AIHA. Design: In this retrospective study, we evaluated the efficacy and safety of
cyclosporine A (CyA) in ITP (N = 29) and AIHA
(N = 10) patients followed at two reference centers in
Milan, Italy. Methods: Responses were classified as partial [Hb > 10 or at least 2 g/dl increase
from baseline, platelets (PLT) > 30 × 109/l with at least
doubling from baseline] and complete (Hb > 12 g/dl or
PLT > 100 × 109/l) and evaluated at 3, 6, and 12 months.
Treatment emergent adverse events were also registered. Results: The median time from diagnosis to CyA was 35 months (3–293), and patients had
required a median of 4 (1–8) previous therapy lines. Median duration of CyA
was 28 (2–140) months and responses were achieved in 86% of ITP and 50% of
AIHA subjects. Responders could reduce or discontinue concomitant treatment
and resolved PLT fluctuations on TPO-RA. CyA was generally well tolerated,
and only two serious infectious complications in elderly patients on
concomitant steroids suggesting caution in this patient population. Conclusion: CyA may be advisable in ITP, which is not well controlled under TPO-RA, and
in AIHA failing rituximab, particularly if ineligible in clinical trial.

Abstract
ATP-binding cassette (ABC) subfamily A member 3 (ABCA3) is a lipid transporter expressed in alveolar type II cells and localized in the limiting membrane of lamellar bodies. It is crucial for pulmonary surfactant storage and homeostasis. Mutations in the ABCA3 gene are the most common genetic cause of respiratory distress syndrome in mature newborns and interstitial lung disease in children. Apart from lung transplantation, there is no cure available. To address the lack of causal therapeutic options for ABCA3 deficiency, a rapid and reliable approach is needed to investigate variant-specific molecular mechanisms and to identify pharmacological modulators for mono- or combination therapies. To this end, we developed a phenotypic cell-based assay to autonomously identify ABCA3 wild-type-like or mutant-like cells by using machine-learning algorithms aimed at identifying morphological differences in WT and mutant cells. The assay was subsequently used to identify new drug candidates for ABCA3 specific molecular correction by high-content screening of 1,280 food and drug administration-approved small molecules. Cyclosporin A (CsA) was identified as a potent corrector, specific for some, but not all ABCA3 variants. Results were validated by our previously established functional small format assays. Hence, CsA may be selected for orphan drug evaluation in controlled repurposing trials in patients.

Incidence and outcomes of refractory immune thrombocytopenic purpura in children: a retrospective study in a single institution. Sci Rep 2021; 11:14263.

Abstract
Treatment of children with refractory immune thrombocytopenic purpura (ITP) is challenging and poorly established. We retrospectively reviewed the clinical data of 87 patients under the age of 16 years who were diagnosed with ITP from April 1998 to March 2017 in our institution. Refractory ITP was defined as a platelet count of < 50 × 109/L at 14 days after receiving intravenous immunoglobulin (IVIG) and prednisolone. We presumed that there was a pathophysiological overlap between refractory ITP and refractory thrombocytopenia (RT): a subtype of refractory cytopenia of childhood (RCC). Immunosuppressive therapies including anti-thymocyte globulin and cyclosporine (CsA) have been adopted for children with RCC in Japan. Thus, from 2009 onwards, we changed the diagnosis from refractory ITP to RT and introduced CsA for refractory ITP/RT. Nine of 42 patients developed refractory ITP in the 1998–2008 group, who received conventional treatments such as IVIG and steroid therapy. Eight of 45 patients developed refractory ITP in the 2009–2017 group, who received CsA with or without IVIG therapy. The response rate at three years after diagnosis was significantly higher in the 2009–2017 group (98%) than in the 1998–2008 group (83%) (p = 0.019). In conclusion, our strategy of introducing CsA for refractory ITP/RT contributed to better outcomes.

Abstract
BACKGROUND The standard therapies for autoimmune cytopenias, including idiopathic thrombocytopenia (ITP), autoimmune hemolytic anemia (AIHA) and Evans syndrome (ES), are corticosteroids and intravenous immunoglobulin G. However, the recurrence rate is high. METHOD Data from 80 patients with ITP, AIHA and ES who were refractory to corticosteroids/relapsed and were treated with tacrolimus from January 2018 to January 2019 in Peking Union Medical Colleague Hospital were reviewed retrospectively. RESULTS There were 24 males and 56 females, with a median age of 43 (14-81) years, including 66 with ITP, 11 with AIHA and 3 with ES. The median disease duration before tacrolimus was 16 (2-432) months. The complete response (CR) rates were 30.3%, 63.6% and 0%; the overall response (OR) rates were 63.6%, 72.7% and 66.7% for ITP, AIHA and ES, respectively; and the median time to response was 3 (2-10) months. In a median of 18 (10-24) months of follow-up time, 21.4% of ITP patients relapsed at a median time of 7 months. No relapse was found for patients with AIHA and ES. Side effects occurred in 16.3% of patients, including elevated creatinine (N = 3, 3.8%), gastrointestinal reactions (N = 3, 3.8%), and pulmonary infection (N = 2, 2.5%), and resulted in 3 patients stopping tacrolimus. The OR rate was found to be related with age (P = 0.01) but not with sex (P = 0.62), the duration of disease (P = 0.66), tacrolimus concentration (P = 0.99) or disease type (P = 0.84). CONCLUSION Tacrolimus can achieve a durable response with mild side effects in patients with steroid-refractory/relapsed autoimmune cytopenias. Patients with younger age had a better response.

Abstract
BACKGROUND Despite an increase in the number of therapies available to treat patients with immune thrombocytopenia (ITP), there are minimal data from randomized trials to assist physicians with the management of patients. OBJECTIVE These evidence-based guidelines of the American Society of Hematology (ASH) are intended to support patients, clinicians, and other health care professionals in their decisions about the management of ITP. METHODS In 2015, ASH formed a multidisciplinary guideline panel that included 8 adult clinical experts, 5 pediatric clinical experts, 2 methodologists with expertise in ITP, and 2 patient representatives. The panel was balanced to minimize potential bias from conflicts of interest. The panel reviewed the ASH 2011 guideline recommendations and prioritized questions. The panel used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, including evidence-to-decision frameworks, to appraise evidence (up to May 2017) and formulate recommendations. RESULTS The panel agreed on 21 recommendations covering management of ITP in adults and children with newly diagnosed, persistent, and chronic disease refractory to first-line therapy who have non-life-threatening bleeding. Management approaches included: observation, corticosteroids, IV immunoglobulin, anti-D immunoglobulin, rituximab, splenectomy, and thrombopoietin receptor agonists. CONCLUSIONS There was a lack of evidence to support strong recommendations for various management approaches. In general, strategies that avoided medication side effects were favored. A large focus was placed on shared decision-making, especially with regard to second-line therapy. Future research should apply standard corticosteroid-dosing regimens, report patient-reported outcomes, and include cost-analysis evaluations.

Abstract
PURPOSE OF REVIEW Medical therapies for the treatment of immune thrombocytopenia (ITP) complicating SLE are increasingly being investigated as alternatives to splenectomy and IVIG. The purpose of this review is to highlight the therapies that are utilized in the treatment of primary ITP and ITP secondary to lupus. RECENT FINDINGS Corticosteroids are still the standard initial treatment of ITP, with the addition of IVIG when a rapid response is needed. There are few studies dedicated to assessing the efficacy of disease-modifying antirheumatic (DMARD), biologic, and nonimmunosuppressive agents as treatment for lupus thrombocytopenia/lupus ITP. Rituximab and thrombopoeitin mimetics have been the most extensively studied therapies for primary ITP in recent years. Results of trials show adequate initial responses; however, the duration of therapy and sustainability of responses are variable. Splenectomy is less often utilized. SUMMARY Although corticosteroids, intravenous immunoglobulin and splenectomy have proven to be effective measures to treat immune thrombocytopenia, newer studies have demonstrated positive outcomes of immunosuppressives and thrombopoeitin mimetics. In most cases, the reported duration of therapy was not prolonged. More studies are needed to fully assess the effect of medical therapy in lupus ITP and to determine how long to continue maintenance therapy.

Abstract
Immune thrombocytopenic purpura (ITP) is an autoimmune condition that affects nearly 1:10,000 people in the world. It is traditionally defined by a platelet count of less than 100 x 109L, but treatment typically depends on symptomology rather than on the platelet count itself. For primary idiopathic ITP, corticosteroids have been the standard first-line of treatment for symptomatic patients, with the addition of intravenous immune globulin (IVIG) or Rho(D) immune globulin (anti-RhD) for steroid-resistant cases. In cases of refractory or non-responsive ITP, second-line therapy includes splenectomy or rituximab, a monoclonal antibody against the CD20 antigen (anti-CD20). In patients who continue to have severe thrombocytopenia and symptomatic bleeding despite first- and second-line treatments, the diagnosis of "chronic refractory ITP" is appropriate, and third-line treatments are evaluated. This manuscript describes the efficacy of different treatment options for primary ITP and introduces the reader to various third-line options that are emerging as a means of treating chronic refractory ITP.

Abstract
INTRODUCTION Immune thrombocytopenia (ITP) is an autoimmune bleeding disorder of heterogeneous pathophysiological mechanisms. Treatment endpoints include elevation of platelets and reduction of bleeding risk, elevation of quality of life, reduction of concomitant therapies and prevention from bleeding. Persistent and chronic ITP is more common in adults but occurs in children. Standard therapies include corticosteroids and immunoglobulins, both associated with side effects. There are new treatments, such as thrombopoietin-receptor agonists and promising investigational drugs. AREAS COVERED Experience from the management of adults is valuable for children with persistent and chronic symptomatic ITP. In this review first- and second-line therapies, but also investigational drugs for children with ITP are discussed. EXPERT OPINION Although time-consuming and based on experience, children with no or mild bleeding can be safely managed with a watch and wait strategy. Chronic symptomatic immune thrombocytopenia is an area of second-line treatments based on a highly individualized approach. Furthermore, there are investigational drugs, which may also be of benefit for children with chronic symptomatic ITP.
