Severe Scedosporium apiospermum Infection in a Recent Renal Transplant Recipient: Case Report.

Infections in transplanted patients are still an important cause of morbidity and mortality. Among them, fungal infections with pathogens have become increasingly more prevalent in the last decade. We report the clinical course and management of disseminated Scedosporium apiospermum infection in a kidney transplant recipient, with microbiological isolation of the fungus in cerebrospinal fluid culture. S apiospermum is a fungus that is distributed worldwide and can be grown from soil samples or stagnant water. Disseminated infection is the most frequent form of infection, with cerebral involvement in most cases, which leads to a very high mortality (around 75%). Post-transplant renal infections require a thorough evaluation. Specifically, a high suspicion index is necessary, considering Scedosporium infection among the differential diagnosis of invasive fungal diseases in renal transplantation patients. It is essential to confirm the microbiological diagnosis for an adequate diagnosis and treatment.

Impact of Asystolic Donations in Kidney Transplant Activity From Cadaveric Donors in Andalusia.

BACKGROUND: Kidneys from donors after brain death (DBD) cannot meet the demand for renal transplants in Andalusia. METHODS: We analyzed the impact of using non-heart-beating donors (NHBD) in Andalusia from the start of this program to the present. RESULTS: From 2010 to 2014, brain-death kidney donations remained at a standstill (1,635 in total) although NHBD increased from 2.4% to 16% annually, to 5% of the total (n = 164: 83 type II Maastricht [NHBD-T2] and 81 type III Maastricht [NHBD-T3]). The donors were more frequently men (T2 80.5% and T3 76.5% vs DBD 58.2%; P < .001). NHBD were younger (48.9 ± 10.8 y vs DBD 53.3 ± 16 y; P < .001); 11.6% of NHBD were >60 and 0% >70 years old, versus 39.4% and 15.2% of DBD, respectively; this is mostly explained by NHBD-T2 (48.9 ± 10.8 y vs DBD 53.3 ± 16 y). NHBD were used much less frequently than DBD in recipients over the age of 65 years or for retransplanted or hyperimmunized patients and never on priority recipients (children and combined transplant patients). Blood groups differed significantly among different donor types (A, O, B, AB): NHBD-T2 65.1%, 27.7%, 7.2%, and 0%, respectively; NHBD-T3 45.7%, 45.7%, 8.6%, and 0%; and DBD 46.5%, 39.4%, 10.2 %, and 3.9% (P = .01). The immediate output of the graft also differed in the proportion of primary nonfunction and delayed graft function: NHBD-T2 9.8% and 70.7%, respectively; NHBD-T3 5.0% and 65.0%; and DBD 5.9% and 28.7%. CONCLUSIONS: The development of an NHBD program allows us to maintain and even increase transplants in our region. The impact on transplant access for O group recipients without priority will depend on the type of NHBD (low proportion of O group in NHBD-T2).

Treatment With Darbepoetin During the First Year After Renal Transplantation: The Starting Point.

INTRODUCTION: Multiple factors are associated with post-transplantation anemia, and renal function is the main factor. The aims of this study were to compare the evolution of hemoglobin in the first year post-transplantation according to darbepoetin (DA) treatment, and factors related to it, to evaluate the difference between earlier versus delayed treatment, and to describe the dose change pattern. PATIENTS AND METHODS: We describe a retrospective study of cohorts in 462 transplant recipients (2004-2011). The variables reported were from donor, transplantation recipient, and DA treatment. RESULTS: In this study, 67.5% of patients were treated with DA, 32.5% were not. The comparison of hemoglobin in both groups during the first year showed a similar evolution with significant differences between consecutive measures until the second trimester. The hemoglobin of the treated group was significantly lower. The evolution of renal function was not different. Multivariate analysis related DA treatment to delayed graft function (DGF) and albuminuria in the first year. Patients with early versus delayed DA introduction did not show a difference regarding length of treatment, but the total dose in the delayed introduction was lower. The evolution of creatinine and hemoglobin was similar in both groups. CONCLUSION: The introduction of DA was related to DGF and albuminuria. The delayed introduction of DA meant the following: less total dose than earlier introduction, no difference in length of treatment, and a similar evolution in hemoglobin and renal function in both groups. The lack of guidelines about DA treatment in renal transplantation makes it difficult to establish a pattern of dose adjustment.

Predictive factors of infection in the first year after kidney transplantation.

BACKGROUND: Infectious disease, a complication favored by immunosuppression, is the main cause of 1st-year mortality in solid organ transplantation. In renal transplant recipients (RTRs), urinary tract infection (UTI) is the most common, and the microorganisms that are isolated depend on chronology. METHODS: We present an observational study comprising 129 RTRs from January 2010 to December 2011 who were followed during the 1st year after transplantation. We analyzed occurrence of infections, predisposing factors, timing, severity, site of infection, and microorganisms. RESULTS: The patients had a total of 424 infectious episodes during the 1st year (3.29 episodes/patient/year). The predominant focus was the urinary tract, with at least 1 episode in 69.8% of patients. Bacteremia was recorded in 25.6% of patients and surgical wound infection in 20.9%. Cytomegalovirus infection or disease was diagnosed in 46.5%. Severe infections occurred in 30.2%. The predominant pathogen was E. coli. There was a significant correlation between hospital stay and the number of infections (P = .000; r = 0.407) and between body mass index and hospital stay (P = .001; r = 0.282). Severe infections were more frequent in diabetics, patients with a double-J stent, and those treated with basiliximab. Patients with cytomegalovirus replication had a higher number of infections (4.1 ± 1.2 vs 2.5 ± 5; P = .000) and significantly higher annual serum creatinine (1.65 ± 5.7 vs 1.31 ± 1.3 mg/dL; P = .003). CONCLUSIONS: The prevalence of infections in the 1st year after kidney transplantation is very high, occurring mainly in the early period, in the urinary tract, and due to E. coli. Cytomegalovirus replication is associated with a higher number of infections and higher serum creatinine at 1 year. Body mass index is a predictor of early infection and of bacteremia in the post-transplantation period. Basiliximab induction and having a double-J stent were predictors of severe infections.
