Carbapenems are a class of antibiotic agents which kill a broad spectrum of bacteria. Infections due to gram-negative bacteria which have acquired resistance to carbapenems are increasing, especially with Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa . The optimal treatment of such infections is not known. Antibiotics like polymyxin, tigecycline and rifampin are used alone or in combination with other antibiotics. The outcome of using these new and old drugs is not well studied. This observational study aims to study the clinical and microbiological outcomes of these infections and treatment at our institution.
1. To define the demographic and risk factor profile of patients acquiring CRGNB infection.
2. To define the characteristics of CRGNB infection.
3. To report the different treatments employed for CRGNB infection.
4. To report the microbiological and clinical outcomes of different treatment options
- a. Microbiological outcomes: frequency of microbiological success. Microbiological success will be defined as two successive negative cultures from the same site as from where the CRGNB was originally isolated.
- b. Clinical outcomes: clinical success (clinical cure), adverse effects of treatment especially the nephrotoxicity in relation to the use of polymyxin, ICU length of stay (if applicable), hospital length of stay, ICU mortality (if applicable), hospital mortality and in-hospital recurrence of infection. Clinical success will be defined as resolution or improvement of clinical symptoms and signs of infection and discontinuation of the antibiotics.
We plan to collect the data for a one year period. Based on the current prevalence rate at our institution, we anticipate having data for 300 patients.

A frequent complication of drug therapy for microbial infection. It may result from opportunistic colonization following immunosuppression by the primary pathogen and can be influenced by the time interval between infections, microbial physiology, or host resistance. Experimental challenge and in vitro models are sometimes used in virulence and infectivity studies.
The ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).
A work that reports on the results of a clinical study in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions (as in an interventional study).
Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.
Simultaneous resistance to several structurally and functionally distinct drugs.
