Therapeutic options for carbapenemase-producing Enterobacteriaceae    

                        
PATRICIA SALGADO, FERNANDO GILSANZ, EMILIO MASEDA              

Carbapenemase-producing Enterobacteriaceae (CPE) has spread worldwide becoming a threat to public health. However, no randomized clinical trials about the efficacy of optimizing antibiotic treatment have been published. Experimental studies have been designed to find combinations of antibiotics with synergistic activity. Their main aim has been increasing the speed of bacterial destruction and decreasing resistance. The latest guidelines recommend combination therapy. The carbapenems has been chosen as the basis of such therapy. We face limited therapeutic options. Polymyxins, fosfomycin and gentamicin have reemerged in this context, becoming the basis of multiple combination regimens, with beneficial effects both in vitro and in murine models of infection.

Inhaled medication and inhalation devices for lung disease     

                        
AMPARO SOLÉ, ROSA Mª GIRÓN              

Nebulized antibiotic therapy is an attractive therapeutic option given the high concentration obtained from the drug at the site of infection, minimizing the adverse effects and possible drug interactions. Inhalation of drugs as treatment of cystic fibrosis (CF) related lung disease has been proven to be highly effective. Consequently, an increasing number of drugs and devices have been developed for CF lung disease or are currently under development. Other limited areas of experience in this field are lung transplant recipients, immunosuppressed patients, bronchiectasis and ventilated patients. In this review document we analyse the current status of the inhaled medications, their modes of administration and indications and their results as well as side effects. Specifically we address antibiotics, and additionally, we review the current knowledge on devices for inhalation therapy with regard to optimal particle sizes and characteristics of wet nebulisers, dry powder and metered dose inhalers. Several factors contribute to a highly variable pulmonary drug deposition as the devices, the physical properties of the administered antimicrobial agent, the type of respiratory disease and the inhalation technique. Despite many clinicians have obtained a valuable experience from the aerosolized administration of antimicrobials and persuaded of their efficacy and safety. However, RCTs out of CF are needed to answer important clinical questions, such as what is the appropriate dose, the optimal delivery device, the optimal way of drug administration, as well as the exact therapeutic role and pharmacokinetic profile of aerosolized drug.

Duration of antimicrobial therapy     

                        
JUAN PASQUAU, MAYRA MATESANZ              

The management of infectious diseases is always complex, not only because of its high incidence and mortality, but the difficulty of designing effective treatments that minimize the development of bacterial resistance in the clinical setting. One of the most important options is the reduction of exposure to antibiotic treatment, optimizing by desescalation and shortening the duration of therapy.

Filamentous fungal infections in immunosuppressed patients: prophylaxis and treatment     

                        
ISABEL RUIZ-CAMPS, MADDALENA PEGHIN              

Although the incidence of invasive aspergillosis has decreased in haematologic patients and solid organ transplant recipients due to the use of prophylaxis; aspergillosis has emerged in other populations undergoing immunosuppressive drugs where prophylaxis is not well defined presenting different clinical patterns. Voriconazole is the gold standard in the treatment of aspergillosis and probably combined therapy, with voriconazole plus anidulafungin, could have a role in the initial management of the infection.

Therapeutic update in hepatitis C     

                        
MARÍA JOSÉ DEVESA, FRANCISCA CUENCA, SONIA IZQUIERDO, PILAR SÁNCHEZ-POBRE, JOSÉ MARÍA LADERO, GUSTAVO LÓPEZ-ALONSO, MANUEL DÍAZ-RUBIO, ENRIQUE REY              

Hepatitis C virus infection is a major health burden affecting 130-170 million people worldwide. Approximately 10-30% of those with chronic hepatitis C will progress to cirrhosis over 20-30 years. The development of new direct-acting antivirals has changed the management of the disease, allowing efficacious Interferon-free therapies superior to prior treatment regimens with minimal side effects, even in some subgroups previously thought to be difficult to cure such as cirrhotic patients.
