Thymomas are the most common masses located in the anterior mediastinum, and they are often associated with autoimmune disorders including myasthenia gravis, polymyositis, and aplastic anemia (AA). Autoreactive T-cell clones generated by the thymoma may lead to autoimmune disorders. We report the case of a 14-year-old boy who was examined for AA, and the underlying cause was determined to be an immune-mediated complication of thymoma. He had no matched sibling donors. He underwent thymectomy, and 3 months later he was treated with immunosuppressive therapy (IST), consisting of antithymocyte globulin and cyclosporine A...

PURPOSE OF STUDY: Immune-mediated adverse drug reactions occur commonly in clinical practice and include mild, self-limited cutaneous eruptions, IgE-mediated hypersensitivity, and severe cutaneous adverse drug reactions (SCAR). SCARs represent an uncommon but potentially life-threatening form of delayed T cell-mediated reaction. The spectrum of illness ranges from acute generalized exanthematous pustulosis (AGEP) to drug reaction with eosinophilia with systemic symptoms (DRESS), to the most severe form of illness, Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)...

Aplastic anemia (AA) is generally considered as an immune-mediated bone marrow failure syndrome. Several studies show that bone marrow mesenchymal stem cells (BM-MSCs), as key cellular components of the bone marrow microenvironment, are also involved in the pathogenic mechanism of AA. Cyclosporin A (CsA) is a classic immunosuppressive drug for AA, and it specifically inhibits mammalian T cells by preventing activation of transcription factors involved in cytokine gene expression. However, little is known about the effect of CsA on the BM-MSCs...

Cyclosporine and aspirin are routinely used in combination to treat immune-mediated hemolytic anemia (IMHA) in dogs. Cyclosporine is a potent immunosuppressive agent that targets T cell production of the cytokines IL-2 and IFN-γ. Low-dose aspirin is often used to inhibit platelet function in dogs with IMHA, since these animals are prone to life-threatening thromboembolic disease. In rodents and humans, aspirin and cyclosporine have both been shown to variably affect T cell cytokine production, and also numbers of circulating regulatory T cells (Tregs)...

OBJECTIVE: To describe the management of cyclosporine overdose using hemodialysis and hemoperfusion in a dog. CASE SUMMARY: A 6-year-old, spayed female Australian Shepherd was presented for treatment of cyclosporine overdose and acute kidney injury. Five days prior to presentation, the dog had been diagnosed by its referring veterinarian with immune-mediated thrombocytopenia. Treatment was initiated with prednisone, but since no response was noted, azathioprine (50 mg PO q 24 h) and cyclosporine (6 mg/kg IV q 24 h) were added...

Although steroids are routinely used as an adjunct to plasma exchange (PEX) therapy in the treatment of immune-mediated thrombotic thrombocytopenic purpura (iTTP), limited data regarding their efficacy or effect on ADAMTS13 biomarkers are available. We report the results of a prospective, randomized study that compared the effectiveness of prednisone or cyclosporine (CSA) as adjuncts to PEX in the treatment of iTTP. A total of 26 of the planned 72 subjects were enrolled and treated from November 2007 until February 2014 before the study was halted after a planned interim analysis...

We have demonstrated that vaccination of cockatiels (Nymphicus hollandicus) with killed parrot bornavirus (PaBV) plus recombinant PaBV-4 nucleoprotein (N) in alum was protective against disease in birds challenged with a virulent bornavirus isolate (PaBV-2). Unvaccinated birds, as well as birds vaccinated after challenge, developed gross and histologic lesions typical of proventricular dilatation disease (PDD). There was no evidence that vaccination either before or after challenge made the infection more severe...

A 5-year-old male castrated Lhasa Apso cross was evaluated for a 1-month history of inappetence, lethargy, gagging, and progressive right thoracic limb lameness. Synovial fluid analysis revealed nonseptic suppurative inflammation, and a diagnosis of immune-mediated polyarthritis (IMPA) was made. After 3 months of treatment with prednisone and later cyclosporine, the dog developed multiple firm cutaneous and subcutaneous masses and a focal mass within the jejunum. Cultures of blood, urine, skin lesions, and the jejunal mass identified Nocardia veterana by matrix-absorption laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) and allowed for earlier identification of the organism compared to more traditional secA1 gene sequencing...

Psoriasis is a chronic, relapsing, inflammatory, immune-mediated systemic disease with mainly skin and joint manifestations. The available treatment options to cure psoriasis include topical therapy, phototherapy, and biological therapy. Biological therapy has become a promising option due to the rapid action and less adverse effects associated with its use. The newly developed biologic itolizumab is a humanized recombinant anti-CD6 monoclonal antibody of IgG1 isotype that binds to domain 1 of CD6, thereby immunomodulating human lymphocytes without interfering with the binding of CD6 to the activated leukocyte-cell adhesion molecule...

PURPOSE OF REVIEW: In this article, we review the indications and latest management of high-risk penetrating keratoplasty. RECENT FINDINGS: Despite the immune-privilege status of the cornea, immune-mediated graft rejection still remains the leading cause of corneal graft failure. This is particularly a problem in the high-risk graft recipients, namely patients with previous graft failure due to rejection and those with inflamed and vascularized corneal beds. A number of strategies including both local and systemic immunosuppression are currently used to increase the success rate of high-risk corneal grafts...

A derivative formula, DGBX, which is composed of three herbs (Radix astragali, Radix Angelicae sinensis, and Coptis chinensis Franch), is derived from a famous Chinese herbal formula, Danggui Buxue Tang (DBT) (Radix astragali and Radix Angelicae sinensis). We aimed to investigate the effects of DGBX on the regulation of the balance between proliferation and apoptosis of hematopoietic stem cells (HSCs) due to the aberrant immune response in a mouse model of aplastic anemia (AA). Cyclosporine (CsA), an immunosuppressor, was used as the positive control...

BACKGROUND: Opportunistic invasive fungal infections (OIFIs) occur in dogs administered immunosuppressive medications. However, the epidemiology of OIFIs among dogs undergoing immunosuppressive treatment is poorly understood. The aims of this study were to (1) estimate the incidence of OIFIs among dogs diagnosed with certain immune-mediated diseases and treated with immunosuppressive drugs, and (2) determine if administration of particular drug(s) was a risk factor for OIFIs. HYPOTHESIS: Dogs receiving cyclosporine treatment (alone or as part of a multidrug protocol) are at higher risk of developing OIFIs...

Hemophagocytic lymphohistiocytosis (HLH) is an immune-mediated disorder resulting in hyper-activation of inflammatory cytokines. If left untreated, the uncontrolled inflammatory response can lead to significant tissue injury and potentially life-threatening multi-organ dysfunction. Conventional immunosuppressive agents are available for the management of HLH, including dexamethasone, cyclosporine, and etoposide; however, patients may not respond to these therapies. Clinicians may turn toward alternative pharmacologic agents that likely have less clinical evidence...

Acquired aplastic anemia, the prototypical bone marrow failure disease, is characterized by pancytopenia and marrow hypoplasia. Most aplastic anemia patients respond to immunosuppressive therapy, usually with anti-thymocyte globulin and cyclosporine, but some relapse on cyclosporine withdrawal or require long-term administration of cyclosporine to maintain blood counts. In this study, we tested efficacy of rapamycin as a new or alternative treatment in mouse models of immune-mediated bone marrow failure. Rapamycin ameliorated pancytopenia, improved bone marrow cellularity, and extended animal survival in a manner comparable to the standard dose of cyclosporine...

AbstractErythema nodosum leprosum (ENL), also known as type II leprosy reaction, is a severe immune-mediated complication of multibacillary leprosy. For ENL, corticosteroids and thalidomide are the mainstays of treatment. Other immunosuppressants, such as clofazimine, cyclosporine, and azathioprine have also been used. Although most patients with ENL respond well to conventional treatments, a small number are refractory to these therapies and have severe morbidity or mortality. We report the case of a 24-year-old man with refractory ENL treated with high-dose corticosteroids for 15 months...

BACKGROUND: Although rabbit anti-T-lymphocyte globulin (ATLG) is largely used for the prevention of immune-mediated complications in patients given allogeneic haemopoietic stem-cell transplantation (HSCT) from an unrelated donor, the optimum dose of this drug in children is still undefined. We aimed to test whether a higher dose of ATLG was superior to a lower dose for prevention of grade II-IV acute graft-versus-host disease (GVHD). METHODS: We conducted a multicentre, randomised, open-label, phase 3 trial in seven Italian centres comparing two different doses of ATLG (30 mg/kg vs 15 mg/kg, given intravenously over 3 days, from day -4 to -2) in children (aged 0-18 years) with haematological malignancies transplanted from an unrelated donor, selected using high-resolution typing for HLA-class I/II loci...

AIMS: Kaposi's sarcoma (KS) is a lymphoangioproliferative multicentric disorder. Among its four distinct clinical variants, iatrogenic KS (iKS) typically affects patients who have received immunosuppressant regimens for organ transplants, proliferative disorders, or immune-mediated diseases. The aim of the current study was to examine the characteristics of a cohort of patients with iKS, evaluating the differences in terms of epidemiological and clinical features, management and outcomes between organ transplant recipients (OTR) and patients immunosuppressed for other medical conditions...

Kawasaki disease is an acute, self-limited vasculitis of childhood and has become the leading cause of acquired pediatric heart disease in the USA. Prompt treatment is essential in reducing cardiac-related morbidity and mortality. The underlying etiology remains unknown. The disease itself may be the characteristic manifestation of a common pathway of immune-mediated vascular inflammation in susceptible hosts. The characteristic clinical features of fever for at least 5 days with bilateral nonpurulent conjunctivitis, rash, changes in lips and oral cavity, changes in peripheral extremities, and cervical lymphadenopathy remain the mainstay of diagnosis...
