Novas estratégias contra as infeções a bacilos de gram-negativo multirresistentes

Abstract

A resistência antimicrobiana é um problema global e emergente, sendo as β-lactamases o principal mecanismo de resistência bacteriana aos antibióticos β-lactâmicos em bactérias de Gram-negativo. Este é um obstáculo que se tem que ultrapassar, de forma a garantir tratamentos eficazes e diminuir a morbilidade e mortalidade associadas às infeções bacterianas comuns. O uso de medicamentos imunossupressores, de antibióticos de largo espectro e de outras classes de medicamentos conduziu ao aumento considerável do número de doentes com infeções causadas por bacilos de Gram-negativo multirresistentes, em todo o mundo. Esta situação evidencia a necessidade urgente em desenvolver não só novos medicamentos, como também em apelar ao uso racional dos antibióticos já existentes. Com o presente trabalho, pretende fazer-se uma revisão dos novos antibióticos que se encontram em ensaios clínicos para combater as infeções a bacilos de Gram-negativo, em especial, os produtores de β-lactamases. Neste contexto será dado um ênfase especial aos novos inibidores não β-lactâmicos das β-lactamases e suas associações com antibióticos β-lactâmicos, avaliando as vantagens e limitações de cada um.

Antimicrobial resistance is a global and emerging problem. β-lactamases are the main mechanism of bacterial resistance to β-lactam antibiotics in Gram-negative bacteria. This is an obstacle that has to be overcome in order to ensure effective treatment and decrease the morbidity and mortality associated with common bacterial infections. The use of immunosuppressive agents, broad spectrum antibiotics and other classes of drugs led to a significant increase in the number of patients with infections caused by multidrug-resistant Gram-negative bacilli worldwide. This highlights the urgent need to develop not only new drugs but also to appeal to the rational use of existing antibiotics. The present work is intended to review new antibiotics that are being developed to combat Gram-negative bacilli infections, in particular, the β-lactamase producers. In this context it will be given a special emphasis on new non-β-lactam β-lactamase inhibitors and their association with β-lactam antibiotics, evaluating the advantages and limitations of each one.
