BACKGROUND: Solid-organ transplants provide a second chance to thousands of critically ill patients with end-organ failure each year. Immunosuppressants are administered to patients to prevent graft rejection of a transplanted organ, such as a heart, kidney, or liver, while placing the recipient at greater risk for infection and cancer. OBJECTIVE: The literature provides evidence of various cancers that have been found to develop in patients' posttransplantation...

Though there is an abundance of information on cutaneous malignancies in transplant recipients, cutaneous infections in solid organ transplant recipients (SOTRs) are underrepresented in the dermatological literature. Our paper provides a comprehensive review of bacterial cutaneous infections within the solid organ transplant population. Cutaneous bacterial infections may lead to significant morbidity and even mortality in this immunosuppressed population. Thus, it is to the benefit of both dermatologists and other transplant care providers to better understand and recognize the features of cutaneous bacterial infections in SOTRs...

Unexpected donor-derived infections (DDI) are relatively uncommon events complicating less than 1% of solid organ transplants (1). Disease can be severe, however, with malignancies and agents that infect the central nervous system carrying a particularly high risk of adverse outcomes (2). In most cases, this risk is managed by a combination of clinical assessment and pre-procurement donor testing. This article is protected by copyright. All rights reserved.

Cytomegalovirus (CMV) infection occurs frequently after solid organ transplantation. Therapeutic strategies, in particular when to start a curative treatment, has not yet been defined. The purpose of this study was to assess predictive factors associated with spontaneous clearance of CMV DNAemia in kidney transplant recipients. METHODS: All kidney recipients of a single center were recruited. Patients with at least one positive CMV DNAemia during the first year post transplantation were included in our analysis...

Invasive fungal infections (IFIs) are a major threat to patients undergoing solid organ transplantation (SOT). Owing to improvements in surgical techniques, immunosuppression therapy and antifungal prophylaxis, the incidence of IFIs has been decreasing in recent years. However, IFI-associated morbidity and mortality remain significant. Invasive candidiasis (IC) and aspergillosis (IA) are the main IFIs after SOT. Risk factors for IC and IA continue to evolve, and thus strategies for their prevention should be constantly updated and targeted to both individual patient risk factors and local epidemiology...

BACKGROUND: Approximately one-third of individuals with interstitial lung disease (ILD) have associated connective tissue disease (CTD). The connective tissue disorders most commonly associated with ILD include scleroderma/systemic sclerosis (SSc), rheumatoid arthritis, polymyositis/dermatomyositis, and Sjögren's syndrome. Although many people with CTD-ILD do not develop progressive lung disease, a significant proportion do progress, leading to reduced physical function, decreased quality of life, and death...

Prolonged exposure to dichlorvos (DDVP), a common pesticide used for food crops, has been related to the development of infections and malignancies. Macrophages are used as bioindicators of immunotoxicity; thus, evaluation of their activity in solid Ehrlich tumor-bearing mice (TBM) may be useful to evaluate the influence of pesticides on human health. To investigate the effects of low DDVP doses, Swiss mice were divided into the following groups: the DDVP group, composed of mice fed diets containing 10 mg/kg of DDVP; the TBM group, consisting of mice subcutaneously inoculated with 107 tumor cells/100 μl and fed a basal diet; the DDVP-TBM group, consisting of mice previously fed DDVP-containing diets for 28 days and then subcutaneously inoculated with tumor cells; and the control (CTRL) group, composed of mice fed a basal diet...

Background: Solid organ transplant recipients (SOTRs) are predisposed to infection due to the need for lifelong immunosuppression, although tools to measure the overall degree of immunosuppression are limited. In this study, we used a novel global cell-mediated immunity (CMI) assay to quantify the degree of immunosuppression and predict subsequent infections. Methods: Consecutive SOTRs were enrolled and provided whole blood to conduct the global CMI assay (QuantiFERON Monitor) at 1, 3, and 6 months posttransplant...

Tick-borne infections in solid organ transplant recipients are an infrequent and difficult diagnostic challenge owing to multiple routes of acquisition and unusual presentations. A 67-year-old male recipient of a combined liver and kidney transplant presented with recurrent fevers following surgery. Standard microbiologic workup was non-diagnostic. Shortness of breath, confusion, lethargy, and hypotension developed along with progressive anemia, requiring multiple blood transfusions. Workup suggested hemolysis and review of the peripheral smear was diagnostic for Babesia microti infection...

Contamination of the preservation fluid (PF) used for donated organs is a potential source of post-transplant infection. However, the information on this issue is scarce. We therefore conducted a systematic review and meta-analysis to assess the incidence of culture-positive PF and its impact on solid organ transplant (SOT) recipients. Seventeen studies were identified and included. The overall incidence of culture-positive PF was 37% (95% CI: 27% to 49%), and the incidence of PF-related infections among SOT recipients with PF cultures that grew pathogenic microorganisms was 10% (95% CI: 7% to 15%)...

BACKGROUND: Vascular graft infections (VGI) are associated with considerable morbidity and mortality, and antimicrobial treatment is an important adjunct to surgical treatment. While microbial aetiology of VGI is often difficult to determine, other techniques such as sonication of implanted material may be used to enhance the recovery of biofilm-associated organisms. METHODS: We performed a retrospective analysis of 22 consecutive patients treated for VGI at University Medical Centre Ljubljana from May 2011 through January 2015...

Post-transplant lymphoproliferative disorder (PTLD) is defined as a heterogeneous group of lymphoid and plasmocytic proliferations with variable malignant potential. They often arise in immunocompromised post solid organ transplant (SOT) patients linked with Epstein-Barr virus (EBV) infection. Clinical manifestations include fever, lymphadenopathy and organ involvement. Diagnosis of PTLD requires morphopathological tissue examination. Treatment of EBV-related PTLD in SOT patients includes immunosuppressive (IS) agents' reduction, use of antiviral medication, anti-B-lymphocyte antibodies and chemotherapy for high-risk patients...

Reactivation of the varicella-zoster virus (VZV) causes dermatomal herpes zoster (HZ) and more rarely severe disseminated HZ including diffuse rash, encephalitis, hepatitis, and pneumonitis. An atypical form of VZV infection, disseminated HZ has been described primarily in immunocompromised hosts. We report 2 cases of atypical disseminated HZ in immunocompromised patients presenting with diffuse, nondermatomal, vesicular eruptions. We also provide a review of the literature and summarize the current guidelines for the treatment and prophylaxis of HZ in patients with human immunodeficiency virus (HIV) infection, solid organ transplantation (SOT), and hematopoietic stem cell transplantation (HSCT)...

Chemotherapy-induced lung toxicity can affect pulmonary parenchyma, pleura, airways, pulmonary vascular system, mediastinum or the neuromuscular system that is responsible for respiration. Chemotherapy-induced pulmonary toxicity is a diagnosis of exclusion. When the patients with malignancies develop pulmonary toxicity such as pneumonitis and distinguishing it from alternative diseases such as infectious, thrombotic, cardiac, malignant or exacerbation of chronic lung conditions can be difficult. Moreover, such patients are often immunosuppressed, physically stressed from the underlying disease and the cancer treatment and hence, more susceptible to usual and unusual or opportunistic infections...

Invasive fungal infections remain a major cause of morbidity and mortality in the solid organ transplant population. Non-Aspergillus infections are of particular concern due to the reduced antifungal susceptibility of many of these fungi (Scedopsorium, Lomentospora, Fusarium etc), the difficulty in distinguishing these organisms from Aspergillus spp based on histopathology alone, and the higher associated mortality observed with these organisms. Current treatment options for these fungi are limited, and voriconazole is the most commonly recommended primary agent1, 2 with combination therapy (terbinafine or an echinocandin) also recommended by some experts...

Cytomegalovirus (CMV) is an agent of global infection, and its acquisition in a population is characterized by an age-dependent rise in seropositivity. After primary infection, CMV remains in the host cells in latent form, and it can reactivate in the case of immune suppression. The risk of CMV recurrence is dependent on the level of incompetency of the immune system, manifested as an impairment of T-cell immunity, including the presence and function of CMV-specific cytotoxic T lymphocytes. This article presents data on the incidence of CMV recurrence in groups of immunocompromised patients, including allogeneic hematopoietic stem cell transplantation (HSCT) patients and other groups of patients, based on a summary of reported data...

BACKGROUND: Infection by Nocardia species is an uncommon cause of severe clinical syndromes, particularly in immunocompromised patients, and solid-organ transplantation is the most common underlying condition. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) has been described thus far in lung and stem cell transplants with systemic nocardiosis. CASE REPORT: We report the first case of SIADH in a female elderly renal transplant recipient diagnosed with systemic nocardiosis 2 years after transplantation...
