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...

Cytotoxic T-cells (CTLs) play an important role in many immune-mediated inflammatory diseases. Targeting cytotoxicity of CTLs would allow to interfere with immune-mediated tissue destruction. Here we demonstrate that WF-10, a pro-oxidative compound, inhibits CTL-mediated cytotoxicity. WF-10 did not influence early steps of target-cell killing, but impaired the ability of CTLs to detach from the initial target cell and to move to a second target cell. This reduced serial killing was accompanied by stronger enrichment of the adhesion molecule LFA-1 in the cytolytic immune synapse...

Amodiaquine (AQ) is associated with a relatively high incidence of idiosyncratic drug-induced liver injury (IDILI) and agranulocytosis. A previous study reported that a combination of high dose AQ and glutathione (GSH) depletion led to liver injury. However, the characteristics of this toxicity were very different from AQ-induced liver injury in humans. We developed a model of AQ-induced liver injury with characteristics similar to the injury in humans by treating mice with lower doses of AQ for several weeks...

Psoriasis is an immune-mediated inflammatory skin disease frequently associated with metabolic disorders, including diabetes, dyslipidaemia and metabolic syndrome. Moreover, a growing number of studies confirm the association between psoriasis and obesity. It has been found that obesity, as measured by body mass index >30 kg/m(2), can double the risk of incident psoriasis. A positive correlation between different measures of adiposity and the severity of psoriasis has also been reported. Epidemiologic studies have also provided robust evidence confirming the association between obesity and psoriatic arthritis...

BACKGROUND: Aplastic anaemia (AA) is a rare acquired bone marrow failure syndrome resulting from the immune-mediated destruction of haemopoietic stem cells. For adults in whom first-line haemopoietic progenitor cell transplantation is not feasible, combination anti-thymocyte globulin (ATGAM) plus cyclosporine A is standard therapy; however, there are minimal data available regarding the optimal ATGAM dosage in terms of efficacy and survival. AIMS: Our institutions have historically used different dosing protocols of ATGAM in the treatment of AA...

Autoimmune lymphoproliferative syndrome (ALPS) is a rare childhood disorder characterized by chronic non-malignant lymphoproliferation and autoimmunity. Patients with ALPS frequently exhibit episodic and intermittent, severe autoimmune- induced hemolytic anemia, thrombocytopenia or combined cytopenias. The co-occurrence of immune-mediated cytopenias, autoimmune thrombocytopenia and autoimmune hemolytic anemia is also known as Evans syndrome. This report describes a child who presented with Evans syndrome symptoms and who, after the detection of increased percentage of double negative T cell population in the peripheral blood, was diagnosed as ALPS...

Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease characterized by hepatocellular inflammation, necrosis, and fibrosis, which can progress to cirrhosis and fulminant hepatic failure. The standard treatment for AIH includes corticosteroids alone or in combination with azathioprine. Although most patients achieve remission using the standard regimen, some patients do not respond due to either drug intolerance or refractory disease; in such cases alternative immunosuppressive agents should be explored...
