Chicken infectious anaemia (CIA) is a disease with a highly economic impact in the poultry industry. The infected chickens are characterized by aplastic anaemia and extreme immunosuppression, followed by the increased susceptibility to secondary infectious pathogens and suboptimal immune responses for vaccination. Commercially available CIA vaccines are routinely used in the breeders in Taiwan to protect their progeny with maternal-derived antibodies. However, CIA cases still occur in the field and little is known about the genetic characteristics of Taiwanese chicken anaemia viruses (CAVs)...

REVIEW
Matthew D Howard, John C Su, Alvin H Chong
The number of solid organ transplants has been increasing annually worldwide. Advances in transplantation surgery and community awareness of organ donation have been key contributors. Combined with increased understanding of immunosuppression, there are a growing number of solid organ transplant recipients in the community as a result of improved long-term outcomes. There remains a high incidence of deaths worldwide post-transplant due to non-melanoma skin cancer (NMSC), which has greater morbidity and mortality in this population than in the general community...

BACKGROUND AND OBJECTIVE: Tacrolimus, a major immunosuppressant used after transplantation, is associated with large interindividual variation involving genetic polymorphisms in metabolic processes. A common variant of the cytochrome P450 (CYP) 3A5 gene, CYP3A5*3, affects blood concentrations of tacrolimus. However, tacrolimus pharmacokinetics at the early stage of transplantation have not been adequately studied in heart transplantation. We retrospectively examined the impact of the CYP3A5 genotype on tacrolimus pharmacokinetics at the early stage of heart transplantation...

Due to medical advances and the availability of efficient immunosuppressive therapies, the life-expectancy of people suffering from inflammatory rheumatic diseases is continuously increasing. In Germany, geriatric patients (definition: age older than 70 years combined with geriatric multimorbidity) affected, e. g. by rheumatoid arthritis (RA) frequently receive corticosteroids and less often biologic disease-modifying antirheumatic drugs (bDMARDs) and conventional DMARDs (cDMARDs), which is justified by additionally existing comorbidities and polypharmacy...

Immune-mediated necrotising myopathy (IMNM) is a type of inflammatory myopathy characterised by acute or subacute severe proximal muscle weakness, significantly elevated creatine kinase levels, and prominent myofibre necrosis and regeneration with little or no inflammation. A subtype of IMNM identified by anti-HMG-CoA reductase (HMGCR)antibodies has been shown to be associated with statin exposure. Treatment of IMNM consists of immunosuppression with steroids, steroid-sparing agents, intravenous immune globulin and/or biologics...

OBJECTIVE: Aging is associated with the development of diseases because of immunosuppression and altered functioning of the neuroendocrine system. The medicinal properties of Morinda citrifolia L. have been widely exploited for the treatment of age-associated diseases. This study aims to investigate the in vitro and in vivo effects of noni (M. citrifolia) fruit juice (NFJ) on neuro-immunomodulation in the lymph node lymphocytes of F344 rats. METHODS: Lymphocytes isolated from axillary and inguinal lymph nodes of young (3-4 months) and old (18-21 months) rats were treated in vitro with different concentrations (0...

For most patients, adenoviruses cause few acute health concerns and are often self-limiting. Patients who are immunocompromised or immunosuppressed, however, are at risk for disseminated adenovirus and suffer high morbidity and mortality, without well-defined treatment options. We report the case of a 9-month-old boy who was successfully treated for disseminated adenovirus infection with intravenous immunoglobulin and cidofovir 3 months post heart transplant, tailored to serum adenoviral load and clinical response...

Progressive multifocal leukoencephalopathy rarely occurs in patients with multiple myeloma. Intracranial central nervous system invasion is also an uncommon event in multiple myeloma, occurring in less than 1% of cases. We describe herein an exceptional case of coexisting progressive multifocal leukoencephalopathy and intraparenchymal central nervous system myeloma infiltration. A 73-year-old woman with relapsed multiple myeloma was treated with 15 cycles of lenalidomide and dexamethasone, but therapy had to be stopped because of a hip fracture after a fall...

Distant metastases are the major cause of mortality in cancer patients. Bone metastases may cause bone fractures, local pain, hypercalcemia, bone marrow aplasia, and spinal cord compression. Therefore, the management of bone metastases is important in cancer treatment. Normal bone remodeling is regulated by osteoprotegerin ligand (OPGL), receptor activator of NF-κB ligand (RANKL), parathyroid hormone-related protein (PTHrP), and other cytokines. In the tumor microenvironment, tumor cells induce a vicious cycle that promotes osteoblastic and osteolytic lesions...

This work investigated, in two large cohorts of French renal transplants treated with tacrolimus, the influence of donor and recipient ABCB1, CYP3A4 and CYP3A5 genotypes on the risk of allograft loss. A discovery and a replication population of 330 and 369 adult renal transplant patients, each from a different transplantation centre and all receiving a tacrolimus-based immunosuppressive regimen, were retrospectively genotyped. The influence of genetic factors and other known risk factors on allograft loss was investigated using multivariate Cox proportional hazard analyses...

BACKGROUND: Traceable and accurate results of cyclosporine A (CsA) mass concentrations in whole blood are required to ensure the monitoring of immunosuppressive therapy in transplant recipients. Metrological traceability and measurement uncertainty can allow ensuring reliability and comparability of these results over time and space. In this study, we provide a practical and detailed example of how the traceability and uncertainty of mass concentration of CsA results, obtained using an ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) procedure, can be described and estimated...

BACKGROUND: Cryptococcosis is an important opportunistic infection of organ transplant recipients. It is the third most common fungal infection of transplant patients and occurs especially in kidney recipients. Cryptococcus neoformans is a ubiquitous fungus which infects humans by inhalation of spores. C. gattii has more recently been recognised as a pathogen. Infection commonly is disseminated affecting mainly the central nervous system and the lungs. Cryptococcoma, a localised form of the disease, has been described in various organs...

Background & Aims: The European Crohn's and Colitis Organization recommends magnetic resonance imaging (MRI) of anal fistulas to decide on the drug/surgery strategy. No evidence is available on the long-term impact of MRI features on fistula healing. The aim of this study was to evaluate the benefit of combined drug/surgery strategies for the treatment of perianal Crohn's fistulas based on MRI factors at referral. Methods: The clinical event (anal abscess, new fistula tract, cellulitis), therapeutic intervention (introduction/optimization of immunosuppressant/biologics, anal surgery, intestinal resection, stoma), and MRI data were prospectively recorded for patients with Crohn's disease (CD) and anal fistulas...

Mycophenolic acid (MPA) has been shown to be promising for the treatment of autoimmune diseases in dogs and cats. In humans, MPA is highly bound to plasma proteins (~97%). It has been recommended to monitor free drug plasma concentrations because the free MPA correlates with its immunosuppressive effect. However, it is unknown if MPA is highly bound to plasma proteins in dogs and cats. The objectives of this study were to determine the extent of plasma protein binding of MPA and evaluate the effect of prednisolone and dexamethasone on the extent of protein binding of MPA in dogs and cats...

Murine models of allograft transplantation are valuable for understanding the immunological mechanisms of allograft acceptance and rejection, the evaluation of immunosuppressive drugs and strategies, and the restoration of functional defects. Herein, we describe methods to create a skin murine allograft surgical model and how to administer adipose-derived stromal cells (ASC) with limited numbers of donor bone marrow to create stable multilineage donor cell chimerism and indefinite immunological tolerance.

Antibodies targeting PD-1 have been demonstrated durable anti-cancer activity in certain cancer types. However, the anti-PD-1 antibodies are less or not efficacious in many situations, which might be attributed to co-expression of multiple inhibitory receptors or presence of immunosuppressive cells in the tumor microenvironment. Most of the anti-PD-1 antibodies used in clinical studies are of IgG4 isotype with the S228P mutation (IgG4S228P ). The functional impact by the interaction of anti-PD-1 IgG4S228P antibody with Fc gamma receptors (FcγRs) is poorly understood...

Group B streptococcus infections (GBSI) are commonly associated with neonates and pregnant women, but may also affect nonpregnant adults. Among its spectrum of manifestations, perinephric abscess (PA) is exceedingly rare. Comorbid conditions such as diabetes mellitus (DM) and immunosuppression increase the risk of GBSI. We describe a 61-year-old Vietnamese man with compensated alcoholic cirrhosis, who presented with acute encephalopathy following subacute, progressive abdominal pain. He was afebrile and hemodynamically stable...

Numerous risk factors have been linked to invasive candidiasis; however, they are nonspecific and often trigger empiric antifungal therapy in a large number of patients. Identification of more precise predictors could promote judicious use of empiric echinocandins. In this retrospective review, 127 patients with blood cultures positive for Candida spp. were compared to a randomly selected cohort of 134 patients on empiric micafungin for ≥3 days and with blood cultures negative for Candida spp. Factors associated with candidemia included total parenteral nutrition (TPN; 26...
