BACKGROUND: Anecdotal reports support the position that the adulticidal heartworm treatment utilizing doxycycline and Advantage Multi®/Advocate® for Dogs (10% imidacloprid + 2.5% moxidectin) has successfully converted antigen-positive dogs to antigen-negative. To date, no controlled experimental studies have demonstrated the adulticidal efficacy of this treatment regimen. The aim of this study was to evaluate the parasitological and clinical efficacy of Advantage Multi® for Dogs (IMD + MOX) and doxycycline in heartworm-infected beagles...

Fungi are ubiquitous in the environment and humans constantly encounter them in the soil, air, water, and food. The vast majority of these interactions are inconsequential. However, in the context of immunodeficiency precipitated by HIV infection, hematologic malignancy, or transplantation, a small subset of fungi can cause devastating, systemic infection. The most deadly of the opportunistic environmental fungi, Cryptococcus neoformans, is estimated to cause hundreds of thousands of deaths per year, mostly in the context of HIV co-infection...

Diverticular disease is frequent amongst the elderly and immunosuppressed patients. It mainly presents as sigmoid diverticulitis, but severe complications, like bleedings, infections and colon perforation may occur, frequently due to immunosuppressive therapy. Moreover, antibiotherapy and hemostatics may not efficiently control evolution in such cases. Early diagnose and adequate treatment of colonic diverticulosis complicated with lower gastrointestinal bleeding and diverticulitis in immunocompromised patients...

Approximately one-third of patients with Crohn's disease do not respond to conventional treatments, and some experience significant adverse effects, such as serious infections and lymphoma, and many patients require surgery due to complications. Increasing evidence suggests that specific changes in the composition of gut microbiota, termed as dysbiosis, are a common feature in patients with inflammatory bowel disease (IBD). Dysbiosis can lead to activation of the mucosal immune system, resulting in chronic inflammation and the development of mucosal lesions...

Left ventricular assist device (LVAD) is one of the modern management therapies in patients with advanced heart failure, and it serves as a bridge to heart transplantation or even as destination therapy. However, it is burdened with a high risk of thromboembolic, hemorrhagic, and infectious complications despite prophylactic management. Splenic abscesses, as septic complications following implantation of mechanical ventricular support, have not yet been described in the literature. We report of a patient with severe left ventricular insufficiency (NYHA II/III), pulmonary hypertension, and arrhythmia who underwent implantation of the Heart Ware® pump for left ventricular support with simultaneous tricuspidvalvoplasty, as a bridge therapy to heart transplantation...

Hepatitis E virus genotype 3 (HEV-3) is the causal pathogen of chronic hepatitis E. We report here the full-length genome sequence of an HEV-3 strain, isolated from a kidney transplant recipient in Switzerland (SW/16-0282). This HEV-3 strain showed less than 88% homology compared to known strains, suggesting a new HEV-3 strain.

In the general population, older age is associated with short leukocyte telomere length and with high risk of infections. In a recent study of allogeneic hematopoietic cell transplantation for severe aplastic anemia, long donor leukocyte telomere length was associated with improved survival in the recipients. These findings suggest that leukocyte telomere length could possibly be a marker of immune competence. Therefore, we tested the hypothesis that shorter leukocyte telomere length is associated with higher risk of infectious disease hospitalization and infection related death...

The acquisition of self-perpetuating, immunological tolerance specific for graft alloantigens has long been described as the "holy grail" of clinical transplantation. By removing the need for life-long immunosuppression following engraftment, the adverse consequences of immunosuppressive regimens, including chronic infections and malignancy, may be avoided. Furthermore, autoimmune diseases and allergy are, by definition, driven by aberrant immunological responses to ordinarily innocuous antigens. The re-establishment of permanent tolerance towards instigating antigens may, therefore, provide a cure to these common diseases...

Candida auris is an emerging, often multidrug resistant pathogen with important public health implications. Infections are associated with high mortality, and prevention of transmission requires stringent infection control measures, making C. auris a potential barrier to transplantation. We describe the first donor-derived C. auris transmission in a lung transplant recipient.

Background.: Infections by multidrug-resistant Pseudomonas aeruginosa (MDRPa) are an important cause of morbidity and mortality in patients after allogeneic hematopoietic stem cell transplantation (HSCT). Humid environments can serve as a reservoir and source of infection by this pathogen. To minimize the risk of infection from these reservoirs, we performed extensive remodeling of sanitation and water installations as the focus of our hygiene bundle. Methods.: During the reconstruction of our transplantation unit (April 2011- April 2014) we implemented several technical modifications to reduce environmental contamination by and subsequent spreading of MDRPa, including a newly designed shower drain, disinfecting siphons underneath the sinks, and rimless toilets...

The association between BK virus infection and hemorrhagic cystitis (HC) in hematopoietic stem cell transplant (HSCT) recipients is well established. However, BK virus-associated HC has not been described in liver transplant (LT) recipients. We present a case of BK virus-associated HC in a LT recipient. Our patient presented with worsening liver function tests 2 years after transplantation and was found to have acute cellular rejection. He was treated with increased immunosuppression and subsequently developed hematuria...

Clostridium difficile infection (CDI) is a well-known complication of antibiotic therapy. It is associated with significant morbidity, mortality, and cost in the hospital setting. The main symptoms include watery diarrhea, abdominal pain, and distension, but CDI can also present as toxic megacolon, bowel perforation with peritonitis, sepsis and renal failure. Therapy includes metronidazole and oral vancomycin, with rectal vancomycin and fecal transplant reserved for more complicated cases. Adjunctive treatments such as probiotics have been tried with mixed results...

Anti-glomerular basement membrane (anti-GBM) disease is a rare small vessel vasculitis that affects the capillary beds of the kidneys and lungs. It is an archetypic autoimmune disease, caused by the development of directly pathogenic autoantibodies targeting a well characterized autoantigen expressed in the basement membranes of these organs, although the inciting events that induce the autoimmune response are not fully understood. The recent confirmation of spatial and temporal clustering of cases suggests that environmental factors, including infection, may trigger disease in genetically susceptible individuals...

BACKGROUND: Clostridium difficile infection (CDI) is a major infectious disease focus for which fecal microbiota transplantation (FMT) has been used with success in various patient populations. METHODS: We conducted a retrospective study of FMT in immunocompetent and immunocompromised patients to review outcomes at our center, with a focus on identifying risk factors for FMT failure in solid organ transplant (SOT) patients. FMT was conducted using universal banked frozen stool via naso-duodenal tube in patients with recurrent CDI of 3 or more episodes per our institutional protocol...

Epstein-Barr virus (EBV) is typically associated with post transplant lymphoproliferative disease (PTLD) after solid organ and stem cell transplantation. However, it is rarely associated with neurological complications. We report a case of severe encephalitis complicating primary EBV infection six months post renal transplantation, and review the literature on EBV encephalitis in solid organ transplantation in adults. A 55-year-old male presented 6 months post cadaveric renal transplant with headache, fever and confusion...
