OBJECTIVE: To determine the survival benefit of kidney transplantation in human immunodeficiency virus (HIV)-infected patients with end-stage renal disease (ESRD). SUMMARY BACKGROUND DATA: Although kidney transplantation (KT) has emerged as a viable option for select HIV-infected patients, concerns have been raised that risks of KT in HIV-infected patients are higher than those in their HIV-negative counterparts. Despite these increased risks, KT may provide survival benefit for the HIV-infected patient with ESRD, yet this important clinical question remains unanswered...

BACKGROUND: The incidence of visceral leishmaniasis (VL) after solid organ transplantation (SOT) is increasing. The optimal therapy for post-transplant VL remains unclear, as relapses after liposomal amphotericin B (L-AmB) are common. Miltefosine has been shown to be effective for treating VL in immunocompetent patients, although data in the specific population of SOT recipients are lacking. METHODS: In the setting of an outbreak of leishmaniasis occurring in Southwest Madrid, we reviewed our experience in 6 SOT recipients with persistent or relapsing VL who received a 28-day course of miltefosine (2...

Hemolytic uremic syndrome (HUS) is a thrombotic microangiopathy defined by thrombocytopenia, non-immune microangiopathic hemolytic anemia and acute renal failure. HUS is typically classified into two primary types: 1) HUS due to infections, often associated with diarrhea (D+HUS, Shiga toxin-producing Escherichia Coli-HUS), with the rare exception of HUS due to a severe disseminated infection caused by Streptococcus; 2) HUS related to complement, such HUS is also known as "atypical HUS" and is not diarrhea associated (D-HUS, aHUS); but recent studies have shown other forms of HUS, that can occur in the course of systemic diseases or physiopathological conditions such as pregnancy, after transplantation or after drug assumption...

Chronic Hepatitis C is a major public health problem. The chronicity of the Hepatitis C can lead to advanced liver disease, cirrhosis and even hepatocellular carcinoma. Chronic hepatitis C is the leading indication of for liver transplantation in the United States. Since the introduction of directly acting antiviral agents (DAAs), there have been there have been dramatic advances in treatment of hepatitis C in terms of tolerability, duration of therapy with significant increases in the rates of sustained virology response (SVR)...

Babesia microti, an intraerythrocytic parasite, is tickborne in nature. In contrast to transmission by blood transfusion, which has been well documented, transmission associated with solid organ transplantation has not been reported. We describe parasitologically confirmed cases of babesiosis diagnosed ≈8 weeks posttransplantation in 2 recipients of renal allografts from an organ donor who was multiply transfused on the day he died from traumatic injuries. The organ donor and recipients had no identified risk factors for tickborne infection...

BKV infection and nephropathy complicate pediatric HTx, but the incidence and time course of the disease are unknown. We assessed the incidence of BKV infection and its association with kidney dysfunction in pediatric HTx recipients. A single center prospective study compared pediatric (<18 years) HTx recipients, with and without BKV infection, who received an allograft between September 2013 and December 2014. Screening of urine for BKV was performed prior to transplant, and at week 1, and at months 3, 6, 9, 12, and 15 months post-transplantation...

Human metapneumovirus (hMPV) is a paramyxovirus that causes respiratory tract infections ranging from mild upper airway infection to severe pneumonia. Patients with haematological disease, especially haematopoietic stem cell transplantation (HSCT) recipients, are more likely to develop more severe infections. We describe three cases of hMPV infection in HSCT patients. The most reliable diagnostic procedure for hMPV is multiplex ligation-dependent probe amplification (MLPA) on a nasopharyngeal swab. Sensitivity and specificity of MLPA to detect hMPV is high and time to diagnosis is short...

BACKGROUND: Diagnosis of engraftment syndrome (ES) following allogeneic hematopoietic stem cell transplantation (HSCT) can be a challenge due to the systemic presentation and alternative etiologies. With a goal of establishing biomarkers to more accurately distinguish ES, we prospectively analyzed levels of cytokines during HSCT. PROCEDURES: We performed a prospective study of children ≤21 years who underwent allogeneic HSCT. Blood samples for interleukin (IL)-6, IL-8, IL-10, IL-1b, IL-12p70, interferon-γ, tumor necrosis factor alpha (TNF-α) and procalcitonin were obtained from each subject prior to conditioning, at day 0, and then biweekly through engraftment and at days 30, 60 and 100...

AIM: To determine if patients with failing kidney transplants who opt to have peritoneal dialysis (PD) have poor short-term PD technique survival and increased rates of peritonitis. METHODS: We performed a retrospective analysis comparing 50 consecutive patients starting PD after a failed kidney transplant to 93 incident patients starting PD (matching for age, gender, diabetes causing renal failure, ethnicity and year of starting PD). RESULTS: The mean follow-up period was 26 months...

We conducted a 17-year nationwide survey (1999-2015) to elucidate the clinical outcomes of patients with primary myelofibrosis (PMF) in Japan. Questionnaires were sent annually to approximately 500 hematology departments. Newly diagnosed patients with PMF were enrolled in this study, and were followed up annually to collect prognostic information. Approximately 50 patients were enrolled per year, yielding a total of 780 patients with PMF included in this study. The median age at diagnosis was 66 years. At the time of analysis, the median survival duration was 47 months, and the 3-year overall survival rate was 59 %...

BACKGROUND: The reasons for improved outcomes associated with preemptive kidney transplantation (PKT) are incompletely understood, and post-transplant complications have been scarcely investigated. METHODS: We evaluated the outcomes of PKT in both unmatched (n = 1060) and propensity score matched cohorts (n = 186) of adults who underwent living kidney transplant between 2000 and 2014. Outcomes were estimated glomerular filtration rate (eGFR), biopsy-proven rejection, cytomegalovirus (CMV) infection, post-transplant diabetes mellitus (PTDM), cardiovascular disease (CVD), graft failure (non-censored for death), and malignancy...

A 24-year-old woman with a high fever presented at our hospital. She had been diagnosed with Kabuki syndrome at the age of 4 years because she had the typical facial features of the condition ; she had undergone living donor renal transplantation 12 years prior. She was prescribed a course of antibiotics to treat pyelonephritis of the transplanted kidney and the high fever disappeared, but the fever developed again 3 days after the discharge. Abdominal computed tomography revealed a tubular structure of recent onset running from the left dorsal side to the lower part of the bladder...

Attenuated poxvirus Modified vaccinia Ankara (MVA) is a useful viral-based vaccine for clinical investigation, because of its excellent safety profile and property of inducing potent immune responses against recombinant (r) antigens. We developed Triplex by constructing an rMVA encoding three immunodominant CMV antigens which stimulates a host anti-viral response: UL83 (pp65), UL123 (IE1-exon4), and UL122 (IE2-exon5). We completed the first clinical evaluation of the Triplex vaccine in 24 healthy adults, with or without immunity to CMV and vaccinia virus (previous DryVax smallpox vaccination)...

Cytomegalovirus (CMV) infection is a significant complication in hematopoietic cell transplantation (HCT) recipients. Four antiviral drugs are used for preventing or treating CMV: ganciclovir, valganciclovir, foscarnet, and cidofovir. With prolonged and repeated use of these drugs, CMV can become resistant to standard therapy, resulting in increased morbidity and mortality, especially in HCT recipients. Antiviral drug resistance should be suspected when CMV viremia (DNAemia or antigenemia) fails to improve or continue to increase after 2 weeks of appropriately dosed and delivered antiviral therapy...

OBJECTIVES: Individuals older than 60 years represent a large proportion of the organs available for orthotopic liver transplant. However, the use of organs from older donors remains controversial. We hypothesized that the use of older donors would not affect patient and graft survival due to significant improvements in donor-recipient management. MATERIALS AND METHODS: We conducted a retrospective cohort analysis using the United Network for Organ Sharing database from February 2002 through December 2012, including non-HCV-infected adults (18 and older) who underwent primary orthotopic liver transplant...

OBJECTIVES: It has been hypothesized that BK polyomavirus infection leads to nephropathy in kidney transplant patients via various plausible mechanisms, such as stimulation of chemokines. The CXCL11 gene may also play a role in BK polyomavirus-associated nephropathy. Our aim was to compare expression levels of CXCL11 in BK polyomavirus-infected versus noninfected kidney transplant patients with nephropathy and healthy controls. MATERIALS AND METHODS: We performed a cross-sectional study of 58 kidney transplant patients with the risk of BK polyomavirus infection; these patients were subgrouped as BK polyomavirus-infected (23 patients) and noninfected (35 patients)...
