BackgroundIn Cushing’s syndrome (CS), when surgery is unsuccessful or contraindicated, ketoconazole is the drug most frequently used to treat hypercortisolism.In July 2013, European Medicines Agency announced their negative risk-benefit assessment of oral ketoconazole as treatment of fungal infections, because it can cause liver damage and drug interactions due to cytochrome P450 inhibition. Ketoconazole was suspended as an antifungal in the European Union, but compassionate use is authorised for CS.PurposeTo analyse the hormonal effects and tolerance of ketoconazole in CS over the last year.Material and methodsNine patients [32–83 years old] were treated in hospital. All patients were retrospectively studied with a follow-up of 26 months; their treatment had lasted from 12 days–25 years. One patient had ectopic ACTH production, two had pituitary adenoma, and six had adrenal neoplasia. Four patients had previously had surgery, but it was not effective in two cases. The dose of ketoconazole was between 200–1,200 mg/day.Liver tests checked: transaminases, total bilirubin and alkaline phosphatase. Hormonal control was observed with Nugent’s test and 24 h urinary free cortisol. The patient’s current treatment was noted to check for drug interactions.ResultsAll patients were checked. No adrenal insufficiency was observed. Liver function tests were normal. Five patients stopped ketoconazole: two for surgery; two died of metastatic cancer; and one because of a potential drug interaction with calcium antagonism. 77.8% of the patients had some possible drug interactions, but only one stopped ketoconazole. Other interactions were with drugs metabolised by CYP450; or with proton pump inhibitors which reduce the pH-dependent absorption of ketoconazole. These problems were solved by changing the dose of the drugs concerned.ConclusionKetoconazole seems to be a safe and efficacious treatment in CS. However, it is necessary to perform a bigger study to get significant conclusions.ReferenceFeelders RA, Hofland LJ, de Herder WW.

BackgroundPleural aspergillosis (PA) was first described in 1842 but remains a relatively rare entity when compared with other Aspergillus infections.PurposeTo describe the pharmacological management of a patient diagnosed with PA and the efficacy of intracavitary instillation of amphotericin B (ICAB) treatment.Material and methodsA 32-year-old woman with multiple drug allergy syndrome (NSAIDs, pyrazolones, quinolones, lincosamides, SSRIs, ondansetron) was admitted to our hospital because of postoperative Pseudomonas pneumonia complicated with empyema and bronchopleural fistula. The patient underwent thoracostomy. Pleural biopsy showed septate fungal hyphae and pleural fluid culture grew Aspergillus fumigatus while serum galactomannan antigen was negative. Systemic antifungal therapy, with oral voriconazole at first and then with posaconazole, was started. Concurrently, amphotericin B deoxycholate, diluted in 75 ml of 5% glucose solution, was infused directly into the pleural cavity, at 5 mg on the first day, rising to 10 mg and 25 mg on the second and third day, respectively, and then 50 mg, after washing of the pleural cavity with 5% glucose solution. Daily dressing with amphotericin B-impregnated gauze was introduced in the cavity. Local treatment was continued for about two weeks.ResultsThe treatment was well tolerated with no adverse drug reactions. The symptoms and the physical signs improved greatly during hospitalisation and the patient left the hospital 3 days after the end of treatment. Repeat pleural fluid culture was negative 2 weeks after the end of treatment.ConclusionICAB may improve the efficacy of systemic antifungal therapy and it should be considered as an additional treatment option. Moreover, the use of this method avoids repeated needling of the cavity and may allow extended treatment on a domiciliary basis.ReferenceKravitz JN, Berry MW, Schabel SI, et al.

Objetivo: conocer si hay precipitación en nutriciones parenterales (NP) con gluconato cálcico y glicerofosfato sódico en las cantidades límites del documento de consenso español de preparación de nutrición parenteral SENPE/SEGHNP/SEFH 2008.Métodos: se prepararon por triplicado siete NP: cinco de 100 ml con concentraciones de aminoácidos, calcio y fósforo similares a las concentracionesmáximas de precipitación del documento consenso SENPE/SEGHNP/SEFH y dos controles, uno sin calcio y fósforo y otro con alto contenido de calcio y fósforo y baja concentración de aminoácidos. Las NP no contenían lípidos. Las NP se almacenaron 20 horas a temperatura ambiente y cuatro horas a 35 °C, y se filtraron con un fi ltro de 0,2 micras. Estos fi ltros se transportaron y observaron parcialmente por microscopía electrónica. Los cristales observados se analizaron por espectrometría por dispersión de rayos X a 1.000 aumentos. Al observarse gran cantidad de precipitados, que no se correspondían a los estudios publicados, se realizaron estudios complementarios para conocer su origen.Resultados: en todos los casos, a excepción del control sin calcio y fósforo, se observaron precipitados. Sin embargo, estos cristales, según nuestros estudios, se produjeron después de la fi ltración y en su composición está el calcio, pero no el fósforo. También se observaron partículas provenientes de la preparación de nutrición parenteral.Conclusiones: en nuestro estudio no encontramos precipitados de fosfato cálcico en los límites recogidos en el documento consenso SENPE/SEGHNP/SEFH. Sin embargo, es posible que se formen microprecipitados con calcio en su composición. Es importante fi ltrar las NP previamente a su administración.
