amphotericin-b--deoxycholate-drug-combination and Acute-Disease

The urinary tract is a common source for life-threatening infections. Most patients with sepsis or septic shock from a urinary source have complicated urinary tract infection. This article explains the epidemiology, risk factors, and treatment. Effective management, appropriate collection of microbiology specimens, prompt initiation of antimicrobial therapy, source control, and supportive therapy are described.

Continuous administration of amphotericin B deoxycholate over 24 hours (24 h-D-AmB) is better tolerated than rapid infusions. However, toxicity and outcome have not been assessed in a homogenous patient population with acute myeloid leukaemia (AML). We retrospectively analysed renal function and outcome in all adult patients with AML undergoing intensive chemotherapy between 2007 and 2012 at our institution. We compared a patient group with exposure to 24 h-D-AmB to a patient group without exposure to 24 h-D-AmB. One hundred and eighty-one consecutive patients were analysed, 133 (73.5%) received at least 1 dose of 24 h-D-AmB, and 48 (26.5%) did not. Reasons for 24 h-D-AmB initiation were invasive fungal disease (IFD) in 63.5% and empirical treatment for febrile neutropenia in 36.5% of the cases. Most patients with IFD received an oral triazole drug at hospital discharge. Baseline characteristics were well matched. Amphotericin B deoxycholate over 24 hours was given for a median 7 days (interquartile range 3-13). Peak creatinine concentration was higher in the 24 h-D-AmB-group (104.5 vs. 76 μmol/L, P < .001) but normalized within 1 month after therapy (65.5 vs. 65 μmol/L, P = .979). In neither of the 2 groups, end-stage renal disease occurred. There was no difference in 60-day survival (90% vs. 90%) and 2-year survival (58% vs. 58%). Invasive fungal disease partial response or better was observed in 68% of the patients. We conclude that antifungal therapy with continuously infused amphotericin B deoxycholate is safe in patients with AML. An antiinfective strategy based on 24 h-D-AmB in first line followed by an oral triazole compound represents an economically attractive treatment option.

Meningitis is a common evolution in progressive disseminated histoplasmosis in children, and is asymptomatic in many cases. In leukemia, the impaired of the T cells function can predispose to the disseminated form. The attributed mortality rate in this case is 20%-40% and the relapse rate is as high as 50%; therefore, prolonged treatment may be emphasized. We have described a child with acute myeloid leukemia (AML), that developed skin lesions and asymptomatic chronic meningitis, with a good evolution after prolonged treatment with amphotericin B deoxycholate followed by fluconazole.

To report the clinical course of a woman with cryptococcal meningitis and no previous cardiac disease who developed a fatal cardiac arrhythmia after an acute overdose of amphotericin B and to review its toxicity.. A 41-year-old woman with a history of proliferative glomerulonephritis from systemic lupus erythematosus was admitted with a diagnosis of cryptococcal meningitis. Liposomal amphotericin B was prescribed at the standard dose of 5 mg/kg/day; however, amphotericin B deoxycholate 5 mg/kg was inadvertently administered (usual dose of the deoxycholate formulation is 0.5-0.8 mg/kg/day). The patient developed cardiac arrhythmias, acute renal failure, and anemia. The medication error was noticed after she had received 2 doses of amphotericin B deoxycholate, and it was then discontinued. Despite treatment in the intensive care unit, the woman died on the sixth day after admission.. Amphotericin B deoxycholate has been reported to produce significant cardiac toxicity, with ventricular arrhythmias and bradycardia reported in overdoses in children and in adults with preexisting cardiac disease, even when administered in conventional dosages and infusion rates. Use of the Naranjo probability scale indicated a highly probable relationship between the observed cardiac toxicity and amphotericin B deoxycholate therapy in this patient.. Given the fulminant course of amphotericin B deoxycholate overdosage and lack of effective therapy, stringent safeguards against its improper administration should be in place.
