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.

We present a 27-year-old lady with HIV-1 infection who died due to rapidly worsening respiratory failure one day after commencing amphotericin B deoxycholate therapy for cryptococcal meningitis. Chest x-ray appearances were consistent with pneumocystis pneumonia but post mortem examination showed evidence of severe necrotizing cryptococcal pneumonia. Cryptococcal pneumonia is an underrecognized condition and should be considered in the differential of patients with HIV-1 infection and low CD4 count who develop respiratory symptoms.
- Comprehensive drug utilization review in neonates: liposomal amphotericin B. [Review]
- JPJ Pharm Pharmacol 2018; 70(3):328-334
- CONCLUSIONS: Although liposomal amphotericin B may be better tolerated and as efficacious as the conventional formulation based on the published literature, the weakness of the studies available on the subject cannot be overlooked. Additional randomized controlled trials are needed to determine the true benefits of this medication.

Protothecosis is an uncommon human infection caused by achlorophyllic algae of the genus Prototheca, especially P. wickerhamii. The skin is the most frequently involved organ and cases of protothecal tenosynovitis are very rare. A 71-year-old woman without prior medical history except hypertension presented with painful swelling of her right hand that did not improve despite receiving antibiotic treatment. She underwent tenosynovectomy and drainage. Histopathologic examination revealed necrotizing granulomatous inflammation and numerous spherical or morula-like organisms with a spoked wheel appearance. P. wickerhamii was identified from tissue culture. The lesion did not improve with empirical fluconazole therapy. Conventional amphotericin B was administered according to antifungal susceptibility tests and the lesion completely resolved. Protothecosis should be considered in the differential diagnosis for chronic tenosynovitis that does not respond to conventional antibacterial treatment; tissue biopsy with culture is required for diagnosis.

Basidiobolomycosis is an unusual fungal skin infection that rarely involves the gastrointestinal tract. This study reported a 5-year-old boy with gastrointestinal basidiobolomycosis that had been misdiagnosed as gastrointestinal lymphoma. He was treated by surgical resection and a combination of posaconazole and amphotericin B deoxycholate with an acceptable response and no recurrence.
- Rapidly Progressive Disseminated Sporotrichosis as the First Presentation of HIV Infection in a Patient with a Very Low CD4 Cell Count. [Journal Article]

Sporotrichosis is a human and animal disease caused by species of the Sporothrix schenckii complex. It is classically acquired through traumatic inoculation of fungal elements. Most frequently, sporotrichosis presents as a fixed cutaneous or as a lymphocutaneous form. A much smaller number of cases occur as cutaneous disseminated and disseminated forms. These cases require immediate diagnosis and management to reduce morbidity and mortality. We present the case of a 34-year-old male patient in whom the first presentation of HIV infection was a rapidly progressive sporotrichosis with multiple cutaneous lesions, a high fungal burden in tissues, and pulmonary involvement. He had an extremely low CD4 cell count (06/mm(3)). Treatment with amphotericin B deoxycholate led to complete clinical resolution. Sporotrichosis remains a neglected opportunistic infection among HIV-infected patients in Rio de Janeiro state, Brazil, and awareness of this potentially fatal infection is of utmost importance if treatment is not to be delayed and if potentially devastating complications are to be avoided.

- Marked peripheral eosinophilia due to prolonged administration of posaconazole. [Journal Article]
- JCJMM Case Rep 2017; 4(6):e005100
- CONCLUSIONS: At the time of writing, there have been only two other published cases of azole-associated peripheral eosinophilia. In reporting this case, we hope to increase health-care provider awareness of this rare adverse event. For patients receiving prolonged therapy with posaconazole, periodic monitoring of the complete blood count with differential may be considered.

Paracoccidioidomycosis (PCM) is a systemic granulomatous disease caused by Paracoccidioides brasiliensis or P. lutzii. It is a neglected tropical infectious disease that poses a major public health burden in endemic areas of Latin America. Mucosae of the upper digestive and respiratory tracts are commonly involved and many patients have disease at multiple mucosal sites, with or without lung involvement. Mucosal PCM presenting as solitary true vocal fold disease is relatively rare. We present the case of a 67-year-old Brazilian forest guard who presented with a 6-month history of hoarseness and globus pharyngeus due to a solitary left true vocal fold infiltration and vegetation diagnosed as PCM. Silent pulmonary disease was also present. A laryngoscopy video is offered as supplemental material to this report. He completely remitted after surgical removal and amphotericin B deoxycholate treatment.
