Immunosuppressive agents

Acquired aplastic anemia (AA) is an immune-mediated bone marrow (BM) failure where marrow disruption is driven by a cytotoxic T-cell-mediated autoimmune attack against hematopoietic stem cells. The key diagnostic challenge in children, but also in adults, is to exclude the possible underlying congenital condition and myelodysplasia. The choice of treatment options, either allogeneic hematopoietic cell transplantation (alloHCT) or immunosuppressive therapy (IST), depends on the patient's age, comorbidities, and access to a suitable donor and effective therapeutic agents...

UNLABELLED: Giant cell myocarditis (GCM) is a potentially lethal subtype of myocarditis. Herein, we report a case of a 22-year-old woman with GCM who was successfully treated with prednisolone monotherapy. The patient had a fever and shortness of breath and was referred to our hospital. Laboratory test results revealed elevated troponin I levels. Cardiac magnetic resonance (CMR) showed high intensity in the inferoseptal segment of the left ventricle on T2-weighted short tau inversion recovery imaging without late gadolinium enhancement (LGE), suggesting predominant edema rather than necrosis...

UNLABELLED: Inflammatory bowel disease (IBD) is a complex chronic inflammatory intestinal disease. The development of de novo IBD after solid organ transplantation with immunosuppressive agents has been rarely reported. We present the case of a 65-year-old man with repeated colitis after heart transplantation (HTx) who was diagnosed with Crohn's disease (CD). The patient underwent HTx due to non-ischemic dilated cardiomyopathy. Six months after HTx, he developed serious diarrhea and a transient fever, which persisted for about 6 months...

BACKGROUND: Immune checkpoint blockers (ICBs) can induce immune-related adverse events (irAEs) whose management is based on expert opinion and may require the prescription of steroids and/or immunosuppressants (ISs). Recent data suggest that these treatments can reduce the effectiveness of ICBs. OBJECTIVE: To investigate the relationship between the use of steroids and/or ISs and overall survival (OS) and progression-free survival (PFS) among ICB-treated patients with an irAE...

UNLABELLED: objective：The management of thyroid eye disease (TED) has undergone significant changes for decades. The study sought to investigate current clinical practice on the management of TED in China. METHODS: An online questionnaire survey was conducted from April to May 2023. The questionnaire involved diagnostic criteria for TED, multidisciplinary treatment (MDT) collaboration, and treatment preference for mild, moderate, and severe TED. RESULTS: A total of 289 questionnaires were collected, with 165 from endocrinologists and 124 from ophthalmologists...

BACKGROUND: While survival rates among cardiac allograft recipients have improved, there has been a rise in post-transplant malignancies, with gastric cancer being less commonly reported. This study presented a successful treatment of gastric cancer in an individual 10 years after undergoing a heart transplant. CASE PRESENTATION: A 66-year-old Chinese man presented to the gastrointestinal clinic with a complaint of diagnosis of gastric cancer for 4 months and treated with neoadjuvant therapy for 1 month...

Large granular lymphocytic (LGL) leukaemia is a rare chronic lymphoproliferative disorder characterized by an expansion of cytotoxic T or NK cells. Despite a usually indolent evolution, most patients will require a treatment over the course of the disease because of cytopenia or symptomatic associated autoimmune disorders. First-line treatment is based on immunosuppressive agents, namely cyclophosphamide, methotrexate and ciclosporin. However, relapses are frequent, and there is no consensus on the management of relapsed/refractory patients...

Despite advances in cancer treatment, hepatocellular carcinoma (HCC), the most common form of liver cancer, remains a major public health problem worldwide. The immune microenvironment plays a critical role in regulating tumor progression and resistance to therapy, and in HCC, the tumor microenvironment (TME) is characterized by an abundance of immunosuppressive cells and signals that facilitate immune evasion and metastasis. Recently, anti-cancer immunotherapies, therapeutic interventions designed to modulate the immune system to recognize and eliminate cancer, have become an important cornerstone of cancer therapy...

Intrahepatic cholestasis of pregnancy is an intrahepatic etiology of acute cholestasis commonly defined by pruritus and increased bile acids, liver transaminases, and, occasionally, bilirubin. Azathioprine is an immunosuppressive agent associated with various forms of hepatoxicity, ranging from transient rises in serum aminotransferase levels, acute cholestatic injury, and chronic hepatic injury. In this report, we present a 20-year-old pregnant woman who presented with cholestatic liver injury due to intrahepatic cholestasis of pregnancy with a clinical picture complicated by increased levels of azathioprine metabolites...

Keratoacanthoma (KA) is a common, low-grade, rapidly growing cutaneous squamous cell carcinoma that presents as an enlarging crateriform nodule, which may spontaneously involute but rarely metastasizes. Immunosuppression, ultraviolet light, viral infection, surgical procedures, and trauma are associated with their development. Overall, tattoo-induced squamous cell neoplasms are infrequently described in the literature. Carcinogenesis is hypothesized to result from trauma caused by the tattooing procedure or a foreign body reaction to the pigment...

BACKGROUND: Patients with a history of hepatitis B virus (HBV) infection who are receiving immunosuppressive therapy are at risk of HBV reactivation and disease. Therefore, HBV screening is required prior to administering antirheumatic drugs with immunosuppressive effects. This study aimed to determine the status of hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), and hepatitis B surface antibody (HBsAb) screening prior to the initiation of drug therapy, including new antirheumatic drugs, in patients with rheumatoid arthritis...

BACKGROUND: Recent evidence shows that immunosuppressive agents can affect the gut microbiota in autoimmune diseases. However, the relationship between the gut microbiome and B-cell depletion immunotherapy in neuromyelitis optica spectrum disorder (NMOSD) remains poorly understood. OBJECTIVES: To evaluate the distinct intestinal microbial patterns and serum cytokine levels after short-term rituximab treatment (three months) in patients with NMOSD. METHODS: Firstly, we conducted a cross-sectional study involving 46 treatment-naïve NMOSD patients and 48 matched healthy controls...

Immunotherapy is an emerging approach for the treatment of solid tumors. Although chemotherapy is generally considered immunosuppressive, specific chemotherapeutic agents can induce tumor immunity. In this study, we developed a targeted, acid-sensitive peptide nanoparticle (DT/Pep1) to deliver doxorubicin (DOX) and triptolide (TPL) to breast cancer cells via the enhanced permeability and retention (EPR) effect and the breast cancer-targeting effect of peptide D8. Compared with administration of the free drugs, treatment with the DT/Pep1 system increased the accumulation of DOX and TPL at the tumor site and achieved deeper penetration into the tumor tissue...

Acquired hemophilia A (AHA) is a rare autoimmune bleeding disorder caused by autoantibodies against FVIII. Severe AHA is life-threatening. Currently, licensed hemostatic agents for the treatment of severe AHA have short half-lives and require intravenous administration, leading to a need for hospitalization, higher costs, and negative effects on quality of life. We present two cases of severe AHA with high inhibitor titers where emicizumab was safely and effectively used with intensive immunosuppression...

OBJECTIVE: Psoriasis patients may have been affected by COVID-19 differently than the normal population due to using different types of treatments, including immunosuppressive agents and biological therapies, the probability of lower effectiveness, and different side effects of the vaccines. This study aimed to evaluate the epidemiologic and clinical features of COVID-19 and the effect of the psoriasis treatment on it. MATERIALS AND METHODS: Psoriasis patients followed up in our clinic between March 2020 and July 2022 were evaluated in terms of clinicodemographic characteristics, treatment methods, and COVID-19 vaccination status and compared regarding COVID-19 history...

Among specific skin manifestations of systemic lupus erythematosus such as leukocytoclastic vasculitis, and vasculopathy, the development of leg ulcers is rare and frequently seen in patients with antiphospholipid antibody positivity. Here we report the rapid healing of a leg ulcer without antiphospholipid antibody positivity in a patient with lupus in response to anticoagulant therapy. As in our case, when immunosuppressive agents are inadequate in lupus patients who develop leg ulcers, it may be beneficial to support the treatment with anticoagulants...

PURPOSE OF REVIEW: Historically, systemic treatments for atopic dermatitis (AD) primarily consisted of immunosuppressive agents such as corticosteroids and Disease Modifying Antirheumatic Drugs (DMARDS), which provided symptomatic relief but often had long-term adverse effects. Newer treatments have shown significant efficacy with less side effects in clinical trials. This review discusses and compares conventional and newer systemic treatments for AD. RECENT FINDINGS: Newer medications for AD including dupilumab, tralokinumab, lebrikizumab, and oral JAK inhibitors have been shown to be safe and efficacious...

Vaccines against coronavirus disease 2019 (COVID-19) have been distributed in most countries for the prevention of onset and aggravation of COVID-19. Recently, there have been increasing numbers of reports on new-onset autoimmune and autoinflammatory diseases following COVID-19 vaccination, however, only little information is available on the long-term safety of these vaccines. Here, we experienced three cases of new-onset rheumatic diseases following COVID-19 vaccination, one case each of rheumatoid arthritis (RA), anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and systemic lupus erythematosus (SLE)...

Azathioprine is recommended as the first-line steroid-sparing immunosuppressive agent for myasthenia gravis. Mycophenolate and methotrexate are often considered as second-line choices despite widespread consensus on their efficacy. We aimed to gather real-world data comparing the tolerability and reasons for discontinuation for these agents, by performing a national United Kingdom survey of side effects and reasons for discontinuation of immunosuppressants in myasthenia gravis. Of 235 patients, 166 had taken azathioprine, 102 mycophenolate, and 40 methotrexate...

Atopic dermatitis (AD) has become a common childhood disease that affects a large number of children worldwide and has become a chronic skin disease that cause a huge economical and psychological damage to the whole family. Despite the use of steroids, immunosuppressants and various topical preparation, the prognosis is still poor. Hence, this review aimed to explore the potential of using essential oils (EO) as an active ingredient in managing AD. The review was completed by using Pubmed, Scopus and Medline to search for relevant articles that study pathophysiology of AD, the properties of EO, the use of EO in managing AD and the suitable advanced formulation to incorporate EO...
