Abstract
BACKGROUND Patients with cancer who are treated with chemotherapy or receive a bone marrow transplant have an increased risk of acquiring fungal infections. Such infections can be life-threatening. Antifungal drugs are therefore often given prophylactically to such patients, or when they have a fever. OBJECTIVES To compare the benefits and harms of lipid soluble formulations of amphotericin B with conventional amphotericin B in cancer patients with neutropenia. SEARCH METHODS We searched PubMed from 1966 to 7 July 2014 and the reference lists of identified articles. SELECTION CRITERIA Randomised clinical trials comparing lipid soluble formulations of amphotericin B with conventional amphotericin B. DATA COLLECTION AND ANALYSIS The two review authors independently assessed trial eligibility and risk of bias and abstracted data. MAIN RESULTS We found 13 trials (1960 patients). Lipid-based amphotericin B was not more effective than conventional amphotericin B on mortality (relative risk (RR) 0.5; 95% confidence interval (CI) 0.64 to 1.14) but decreased invasive fungal infection (RR 0.65; 95% CI 0.44 to 0.97), nephrotoxicity defined as a 100% increase in serum creatinine (RR 0.45; 95% CI 0.37 to 0.54), and number of dropouts (RR 0.78; 95% CI 0.62 to 0.97).For the drug used in most patients, AmBisome (4 trials, 1214 patients), there was no significant difference in mortality (RR 0.77; 95% CI 0.54 to 1.10) whereas it tended to be more effective than conventional amphotericin B on invasive fungal infection (RR 0.63; 95% CI 0.39 to 1.01, P value 0.053).AmBisome, amphotericin B in Intralipid (6 trials, 379 patients), amphotericin B colloidal dispersion (ABCD) (2 trials, 262 patients), and amphotericin B lipid complex (ABLC) (1 trial, 105 patients) all decreased the occurrence of nephrotoxicity, but conventional amphotericin B was rarely administered under optimal circumstances. AUTHORS' CONCLUSIONS It is not clear whether there are any advantages of lipid-based formulations if conventional amphotericin B is administered under optimal circumstances, and their high cost prohibits routine use in most settings. There is a need for large trials comparing lipid-based formulations of amphotericin B with conventional amphotericin B given in the same dose, with routine premedication for prevention of infusion-related toxicity, and with supplementation with fluid, potassium, and magnesium for prevention of nephrotoxicity.

Abstract
The advances in science have resulted in the emergence of nanotechnology, which deals with the design and use of tools and devices of size 1-100 nm. The application of nanotechnologies to medicine is thus termed nanomedicine. Significant research has been focused on this new and exciting field and this review article will describe the basics of nanomedicine. This is followed by its experimental and clinical applications in diagnostics, drug therapy and regenerative medicine. Safety issues of in vivo use of nanomaterials are also discussed. In the future, it is foreseen that nanomedicine will facilitate the development of personalized medicine and will have a major impact on the delivery of better healthcare.

Abstract
The authors report on a 14-year-old adolescent boy suffering of Hodgkin disease in remission, who developed autoimmune anemia and thrombopenia. He was treated with high-dose steroids and he developed serious invasive lung aspergillosis, which was treated with antifungal agents and surgical intervention. Children suffering from cancer are prone to develop systemic fungal infections secondary to the severe immunosuppression caused by the disease itself and the antineoplastic therapy. Intravenous antifungal medications and, when feasible, surgery are used for treatment of pulmonary aspergillosis. Factors related to better outcome are early diagnosis, remission of underlying disease, aggressive antifungal therapy, and recovery from neutropenia.

Abstract
Invasive fungal infections often prove difficult to eradicate especially in the stem cell transplant setting. Amphotericin has been the mainstay of treatment for years but has significant toxicity. Newer antifungal agents, such as caspofungin, have shown promising results in adults, particularly when used in combination with amphotericin as both drugs differ in their mode of action. However, there are few data from children and no previous published information about the use of Caspofungin after paediatric stem cell transplantation. We report our experience in children with proven invasive fungal infections after stem cell transplantation. This combination was non-toxic, and two of three patients survived their infections.

Abstract
Invasive fungal infections are rare but life-threatening infections, most often occurring in immunocompromised patients. For a long time, Amphotericin B has been the best choice for treatment, because it is fungicidal with a broad antifungal spectrum and minimal risk of resistance development. The therapeutic use of amphotericin B has, however, been limited by its toxicity-both acute as well as chronic. To counter this, amphotericin B has been encapsulated in liposomes, which reduces its toxicity and allows higher doses to be given. Ambisome is a true, spherical, small unilamellar liposome with a median size of 80 nm. The pharmacokinetic profile was changed, and the maximum concentration and AUC of amphotericin B after AmBisome treatment were greater than those found with the conventional drug. The highest tissue concentrations of AmBisome were found in the liver and spleen, and less than 1% of the administered dose was recovered in other organs. At Huddinge University Hospital, we were the first to use and report on the experience of AmBisome. We now have more than 12 years' experience in transplant recipients, with a good safety profile, improved rate of curing mycological proven infections and reduced mortality in fungal infections. In two placebo-controlled prophylactic trials, we found that AmBisome was effective for preventing fungal colonization and invasive fungal infections, respectively, in allogeneic stem cell and liver transplantation. In uncontrolled and, more recently, in randomized controlled studies at other centers, AmBisome has revealed less toxicity and an efficacy equal or superior to that of the conventional drug in treating neutropenia-associated fever and proven invasive fungal infections in both adults as well as in children. Although investigators tend to increase the dose used, the optimal dose for probable or proven infection is still under debate. Based on our own experience in using AmBisome and the experience at other centers, we can conclude that AmBisome represents a major breakthrough in the treatment of invasive fungal infections, especially in immunocompromised patients.

Abstract
BACKGROUND Patients with cancer who are treated with chemotherapy or receive a bone marrow transplant have an increased risk of acquiring fungal infections. Such infections can be life-threatening. Antifungal drugs are therefore often given prophylactically to such patients, or when they have a fever. OBJECTIVES To compare the effect and adverse effects of AmBisome and other lipid soluble formulations of amphotericin B with conventional amphotericin B in cancer patients with neutropenia. SEARCH STRATEGY MEDLINE and Cochrane Library. Unpublished trials from conference proceedings and contact to industry. SELECTION CRITERIA Randomised trials comparing lipid soluble formulations of amphotericin B with conventional amphotericin B. DATA COLLECTION AND ANALYSIS Data on mortality, invasive fungal infection, nephrotoxicity, serum creatinine and dropouts were extracted by both authors independently. MAIN RESULTS AmBisome vs conventional amphotericin B (3 trials, 1149 patients): AmBisome tended to be more effective than conventional amphotericin B for invasive fungal infection (relative risk 0.63, 95% confidence interval 0.39 to 1.01, P=0.053) whereas there was no significant difference in mortality (relative risk 0.74, 95% CI 0.52 to 1.07). AmBisome decreased significantly the incidence of nephrotoxicity, defined as a 100% increase in serum creatinine (relative risk 0.51, 95% CI 0.40 to 0.64). Fewer patients dropped out on AmBisome but the difference was not significant (relative risk 0.78, 95% CI 0.56 to 1. 08). Amphotericin B in Intralipid vs conventional amphotericin B (4 trials, 145 patients): There were no significant differences in clinical effect whereas the patients treated with the lipid soluble formulation experienced significantly less nephrotoxicity (relative risk 0.34, 95% CI 0.15 to 0.75) and smaller increases in serum creatinine (weighted mean difference 32 micromol/l, 95% CI 21 to 43 micromol/l). Amphotericin B colloidal dispersion (ABCD) vs conventional amphotericin B (1 trial, 213 patients): There was lower nephrotoxicity with ABCD (relative risk 0.38, 95% CI 0.25 to 0.59). REVIEWER'S CONCLUSIONS AmBisome is a better drug than conventional amphotericin B but its high cost prohibits routine use in most settings. Furthermore, the advantages of AmBisome may be smaller than indicated in our review if conventional amphotericin B is administered under optimal circumstances. It is not clear whether other lipid formulations of amphotericin B could offer a worthwhile advantage compared to conventional amphotericin B.

Abstract
Fungal infections have emerged as one of the most significant complications of antineoplastic therapy and marrow transplantation in children. Morbidity and mortality associated with fungal infections are high. Recent trends indicate that the incidence and spectrum of fungal infections are increasing, partly because of the increase in the number of children receiving intensive chemotherapy and marrow transplantation, but also because of the successful management of bacterial and viral infections. Though many factors may contribute to risk for developing a fungal infection, prolonged neutropenia is the most important. Until recently, options for antifungal therapy were limited. Advances include less toxic formulations of amphotericin B and an expanding armamentarium of azoles as well as new antifungal compounds. This review addresses the therapeutic options available for treatment of fungal infections in immunocompromised children.

Abstract
BACKGROUND Disseminated fungal infections are a major problem in high risk neonates. Conventional antifungal agents are often unsatisfactory and have a high incidence of severe adverse effects. METHODS We administered liposomal encapsulated amphotericin B (AmBisome), which is an alternative to conventional amphotericin B, to 40 preterm (mean birth weight, 1090 +/- 313.6 g; mean gestational age, 28.35 +/- 2.13 weeks) and 4 full term (mean birth weight, 3080 +/- 118 g; mean gestational age, 39 +/- 0.7 weeks) newborn infants with a severe fungal infection. RESULTS Candida albicans was the most frequent fungus isolated (70%). The duration of intravenous AmBisome therapy ranged from 7 to 49 days; the cumulative dose ranged from 7 to 138.8 mg/kg (median, 45.2 mg/kg). Administration of AmBisome was effective in 72.7% of patients; 5 of 6 cases of meningitis also recovered; 63.6% of 33 very low birth weight infants survived. No side effects were observed. CONCLUSIONS To our knowledge this is the largest study of the treatment of neonates with liposomal amphotericin B, and the results confirm its effectiveness and safety. However, randomized clinical trials are required to establish the most effective administration protocol for AmBisome, i.e. the starting dosage, the maximum effective dosage and the cumulative dosage, and to verify whether the preparation should be associated with another antifungal agent.

Abstract
Systemic fungal infection occurs in 2 to 4.5% of very low birth-weight (VLBW) infants (< 1,500 g) and may be fatal in 25 to 54%. Candida sp. is the major pathogen and amphotericin B the treatment of choice. To reduce side effects and optimize drug action, a formulation of amphotericin B encapsulated in liposomes (AmBisome) has been introduced. Data on 21 VLBW infants who received a full course of AmBisome was collected and its toxic effects with emphasis on nephrotoxicity and hypokalemia assessed. The median gestational age was 25 weeks (range 23-31) with a median birth-weight of 730 g (range 450-1,370). Antifungal therapy was started at a median age of 13 days (range 1-49). The median dose given was 2.6 mg/kg/day (range 1-5), and the median duration of therapy was 28 days (range 11-79), corresponding to a median cumulative dose of 71 mg/kg (range 12-271). Hypokalemia (< 3.0 mmol/l) was observed in 30% before, and 15% during AmBisome treatment. Twenty-one days after the termination of therapy, hypokalemia was not present in any patient. Median maximum daily potassium supplementation did not exceed doses usually recommended for VLBW infants. The median of the maximum creatinine levels before treatment was 121 mumol/l (range 71-221) and fell to 68 mumol/l (range 31-171) during treatment and 46 mumol/l (range 26-62) 21 days after the termination of therapy. All patients treated with AmBisome eradicated fungi and recovered clinically. AmBisome showed no certain nephrotoxicity in VLBW infants in this study.

Abstract
PURPOSE Four children with an osteomyelitic process in the jaw bones while on cytotoxic chemotherapy were treated by radical surgery and antimicrobial chemotherapy. PATIENTS AND METHODS Symptoms (local swelling and pain in the jaw, necrotic gingivitis, and spontaneous loss of teeth) appeared 3 weeks, 4 weeks, and 8 months after diagnosis of leukemia, and 8 days posttransplant in a patient with severe aplastic anemia. Three had the process in the mandible and one in the maxilla. Specific diagnoses of Aspergillus flavus, Saccharomyces cerevisiae, and Actinomyces species were obtained histologically from surgical samples. Treatment was radical surgery to remove all infected and necrotic tissue: removal of a substantial part of the mandible and loss of seven to eight permanent teeth in those with mandibular lesions. Actinomycosis was treated with penicillin for 2 years. The patients with fungal lesions received amphotericin B for 2, 5, and 6 months, with adjuvant itraconazole, fluconazole, or 5-fluorocytosine for 9-12 months. Anti-cancer chemotherapy was continued. RESULTS All the bony lesions healed. The patient with acute myeloid leukemia died in relapse 1 year postdiagnosis; her aspergillus osteomyelitis had been inactive for 8 months. The other three patients are alive and well 1.9, 2.1, and 1.9 years after termination of antimicrobial therapy. CONCLUSIONS We emphasize the necessity of specific diagnosis from appropriate surgical samples and conclude that in patients undergoing chemotherapy bony lesions caused by opportunistic microorganisms may be curable with aggressive surgery and prolonged medication.

Abstract
Five children with malignancies developed invasive pulmonary aspergillosis during chemotherapy-induced neutropenia. All patients were treated with liposomal amphotericin B and human recombinant granulocyte colony-stimulating factor. Two patients did not recover from bone marrow aplasia and died from organ-infiltrating fungal invasion. Two patients who recovered from bone marrow aplasia survived after surgery of the pulmonary lesions. The fifth patient had a complete resolution of invasive pulmonary aspergillosis after neutrophil recovery without surgical intervention. We conclude that not only the antifungal treatment but also the recovery of granulocytes are important in localizing invasive forms of Aspergillus infections in patients with profound immunosuppression.

Abstract
OBJECTIVE To examine the range of disease caused by invasive Candida infection in neonates and infants and to discuss the available treatment options, particularly surgery and drug therapy. PATIENTS AND METHODS Five consecutive infants with invasive urinary tract Candida infection presenting over an 18-month period were reviewed. Treatment protocols included a combination of surgery and treatment with amphotericin, flucytosine and fluconazole. RESULTS The range of disease severity from simple Candida urinary tract infection to overwhelming multi-organ sepsis was demonstrated. Urinary tract obstruction was identified as a predisposing factor in three of the five cases. In all cases, infection was cleared by the treatment protocol. Two cases with bilateral renal pelvic fungal balls showed resolution with no surgery in three kidneys and showed no advantage of pyelotomy and perfusion. CONCLUSION The results question the role of surgery, which may be limited to the relief of primary urological obstruction. We advocate the use of oral fluconazole to prevent or treat early systemic infection and, for severe systemic infections, a prolonged course of fluconazole in combination with flucytosine should be considered as an alternative to amphotericin, which is toxic and can only be given intravenously.

Abstract
BACKGROUND Most cases of mucormycosis occur in immunosuppressed children. Intracranial extension is lethal and must be prevented with early specific treatment. CASE REPORT A 42 month-old boy was admitted suffering from acute lymphoblastic leukemia. Edema of the left eyelid developed on the sixth day of induction chemotherapy. Mucormycosis was suspected because of gradual extension of infection to nasal ala and periorbital area with fever, edema of nasal turbinates and nasal black secretions. Chemotherapy was discontinued and the patient was given intravenous amphotericin B (1.0 mg/kg/day) and heparin associated with G.CSF. Improvement was only temporary and scan examination performed on day 17 showed involvement of the orbit, eye and wall of the maxillary sinus; cultures of secretions were positive for staphylococcus and Absidia corymbifera. Remission of leukemia was obtained a few days later permitting surgical resection of involved tissues on day 30. A relapse of mucormycosis was observed six weeks later despite prolonged administration of amphotericin B requiring extended resection of necrotic areas and replacement of amphotericin B by its liposomal form (Ambisome). Bone marrow relapse of leukemia required further chemotherapy. The patient is in good condition 30 months after the initial symptoms. CONCLUSION Our patient seems to be the first with prolonged remission of facial mucormycosis and acute leukemia despite relapse of both diseases. This favorable outcome could be due to the use of Ambisome.

This relapsed after a prolonged course of amphotericin B and flucytosine. An eight week course of liposomal amphotericin produced a marked clinical improvement which was sustained for one year. A subsequent relapse was associated with transformation to myelodysplastic leukaemia.

Abstract
Various formulations have been developed in an effort to reduce the toxicity of amphotericin B. We report a case of cryptococcal meningitis in a 31-year-old HIV-positive man which was successfully treated with amphotericin B lipid emulsion.

Abstract
The unilamellar liposomal formulation of amphotericin B, AmBisome, is composed of hydrogenated soy phosphatidylcholine, distearoyl phosphatidylglycerol and cholesterol. Early studies of its efficacy in an open design showed that remissions could be induced in candidosis and aspergillosis and that doses of up to 5 mg/kg could be used. Adverse events were infrequent, with the main abnormality seen being hypokalaemia in about 18% of patients. Subsequent developments have extended this work. AmBisome has been used in two open studies of patients with invasive aspergillosis; in one of these remission was achieved in 77% of 17 patients with confirmed infection who had failed to respond to conventional amphotericin B. In AIDS patients with cryptococcosis AmBisome given for 6 weeks at 3 mg/kg daily produced mycological remission of meningitis in 67%. Other infections treated with the drug include zygomycete (mucormycosis) and Fusarium infections. AmBisome has also been used as preventative therapy in bone marrow transplant recipients and was found to reduce fungal colonisation rates. There were fewer systemic fungal infections in the treated versus placebo groups although this did not achieve statistical significance. Lack of renal and liver toxicity or anaemia has been confirmed in subsequent studies. In addition febrile reactions to the AmBisome are rare. The drug has also been used effectively in children, including infants, with systemic fungal infections. In visceral leishmaniasis patients, including HIV positive individuals, remissions have been obtained using drug regimens of 1-2 mg/kg of 2.1 days and 3 mg/kg for 10 days.

Abstract
Conventional amphotericin B (Amph-B) is the drug of choice for treating systemic fungal infections. Recently, a new formulation has become available, encapsulated in liposomes (Amph-lip). This new form of administration was developed in order to lower the acute side effects and to offer the possibility of administering high doses of amphotericin B. Experience with Amph-lip is limited, especially in children. We treated four children with documented systemic fungal infections with Amph-lip and administered it empirically to 12 children. Fifteen of these 16 children were severely granulocytopenic oncologic patients. One 3-month-old baby suffered from systemic candidiasis. Amph-lip was preferred to conventional Amph-B in children with organ dysfunction developing as a consequence of conventional chemotherapy or bone marrow transplantation, after failure of conventional Amph-B to improve a fungal infection, and after adverse drug reactions had occurred. The daily doses of Amph-lip ranged from 1 to 6 mg/kg (median 3 mg/kg), the cumulative doses from 13 to 311 mg/kg (median 75 mg/kg). Acute adverse reactions or organ function abnormalities attributable to Amph-lip did not occur in 402 administrations. Amph-lip has proven to be well tolerated by children in terms of acute toxicity and in the long term. Although large cumulative doses were given, organ function abnormalities attributable to Amph-lip doses were not detected in any of ten long-term survivors over a median observation time of 36 months (range 30-44 months). Amph-lip appears to be a promising alternative antifungal treatment, especially for patients with impaired organ function, when high doses of amphotericin B are necessary.
