The extent to which donor multidrug‐resistant organisms (MDROs) affect organ utilization remains unclear. We performed a retrospective cohort study at 4 transplant centers between 2015 and 2016 to evaluate this question. All deceased donors who donated at least one organ were included. Exposed donors had at least one MDRO on culture. Unexposed donors had no MDRO‐positive cultures. Only cultures obtained during the donor's terminal hospitalization were evaluated. Multivariable regression was used to determine the association between donor MDRO and (1) number of organs transplanted per donor and (2) the match run at which each organ was accepted. Subsequently, we restricted the analysis to donors with MDR‐Gram‐negative (GN) organisms. Of 440 total donors, 29 (7%) donors grew MDROs and 7 (2%) grew MDR‐GNs. There was no significant association between donor MDRO and either measure of organ utilization. However, donor MDR‐GNs were associated with a significant reduction in the number of organs transplanted per donor (incidence rate ratio 0.43, 95% confidence interval [CI] 0.39‐0.48, P < .01), and organs were accepted significantly further down the match list (relative count 5.08, 95% CI 1.64‐15.68, P = .01). Though donor MDR‐GNs were infrequent in our study, their growing prevalence could meaningfully reduce the donor pool over time.
Infective endocarditis is a common clinical problem in industrialized countries. Risk factors include abnormal cardiac valves, a history of endocarditis, intracardiac devices, prosthetic valves and intravenous drug use. We report a case of polymicrobial infective endocarditis in a 33 year-old female with a history chronic heroin use caused by Neisseria sicca and Haemophilus parainfluenzae. We believe the patient was exposed to these microbes by cleansing her skin with saliva prior to injection. Pairing a detailed history with the consideration of atypical agents is crucial in the proper diagnosis and management of endocarditis in patients with high-risk injection behaviors.
Antibiotic use in deceased organ donors has not been previously described. In a retrospective cohort of 440 donors, we found 427 (97%) received at least one antibiotic course, 312 (71%) received broad-spectrum antibiotics, and 61 (14%) received potentially redundant antibiotics during their terminal hospitalization, suggesting a need for stewardship.
Patient: Female, 29Final Diagnosis: MalariaSymptoms: FeverMedication: —Clinical Procedure: —Specialty: Infectious DiseasesObjective:Unusual setting of medical careBackground:Malaria infection during pregnancy is associated with increased perinatal and maternal morbidity and mortality.Case Report:A 29-year-old primigravida at 37 weeks of gestation, with no significant medical history, presented complaining of fever, chills, and generalized body aches. She had been living in Malawi for 1 year and was on atovaquone/proguanil prophylaxis until she was found to be pregnant. Prophylaxis was changed to mefloquine and discontinued upon her return to the US. Six weeks prior to presentation, she traveled to Malawi for 1 month when she was off prophylaxis. On admission, vital signs and physical exam results were normal. Given epidemiologic findings, a malaria smear was performed and showed 4% parasitemia. She was treated with mefloquine and discharged. Two days after discharge, she again presented with fever, chills, and body aches. A malaria smear showed <0.01% parasitemia, with 2 ring forms. Serologies for dengue, chikungunya, leptospira, and blood cultures were negative. These symptoms were deemed secondary to early recrudescence. The species was later identified as P. falciparum. The patient was treated with quinine sulfate and clindamycin. She delivered at full term without complication.Conclusions:Pregnant women are more susceptible to severe forms of malaria, such as P. falciparum. A high index of suspicion and early identification of malaria are vital to prevent deleterious outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
