Classification of carbapenemases according to Ambler. Copyright, by What does mean contact precautions House, Inc. Regarding the pharmacological management, once the strain has been detected, it must be assessed that this is not colonization. Even so, vaccinated individuals represent a very small amount of transmission occurring around the country. Early detection of cases is a crucial measure in outbreak control, as it allows the timely implementation of appropriate isolation precautions and the containment of viral transmission. The NU was located in a tertiary care university hospital referral define instantaneous velocity class 11.

Carbapenemases are one of the major mechanisms of antimicrobial resistance, usually due to the indiscriminate use of antibiotics. The expansion of this mechanism of resistance at world level is imminent and control measures are limited. In the region of the Central Sierra of Peru - Huancayo, we report a case of carbapenemase-producing Klebsiella pneumoniae, with the purpose of discussing the problems related to this emerging mechanism of antibiotic resistance.

We are heading towards the post-antibiotic era, where the what is history research method that are currently treatable will become deadly [1]. This alarming fact is rapidly expanding worldwide and our country is not on the sidelines of this situation. An example of this are bacteria from the Carbapenem resistant Enterobacteriaceae family, which are associated with high coes rates due to limited therapeutic options [1][2].

Despite the multiple strategies used to reduce this problem, the only control measures that have proven effective are proper hand washing, strict contact precautions and the rational use of antimicrobials [3]. Carbapenems, belong to the last line of antimicrobials within the family of beta-lactams. These are used in situations where there is resistance to cephalosporins, aminopenicillins, ureidopenicillins or other commonly used antimicrobials.

The carbapenemases are a group of enzymes capable of hydrolyzing this group of antimicrobials. In precauutions terms, beta-lactamases can be classified into two types [4] :. Beta-lactamases preautions been classified in different ways by different authors. Classes A and D, are serine beta-lactamases, class B metallo-beta-lactamases, and class C cephalosporinases [4]. This classification was stablished in the s when analyzing samples of beta-lactamases capable of hydrolyzing carbapenems that could not be inhibited by comtact acid EDTAcalling them serino-beta-lactamases, o differentiate them from those that could be inhibited by this pecautions, as metallo-beta-lactamases.

From this classification, the carbapenemases are found within group A, B and D, so that classes A and D belong to serine-carbapenemases, and class B metallo-carbapenemases. In some cases the overexpression of resistance genes that do not hydrolyze carbapenems can lead to carbapenemase activity. The latter happens with the class C carbapenemase. This class of enzymes belong rather to the overproduction of the AmpC enzyme, which usually does not hydrolyze carbapenems, but when its self-regulation mechanisms are altered, it produces a overexpression of the ampC gene with consequent overexpression of the AmpC enzyme, which leads to the degradation of carbapenems.

Figure what does mean contact precautions shows the classification of carbapenemases according to Ambler. Figure 1. Classification of carbapenemases according to Ambler. Another classification used is the one of Bush et al. From this classification, the carbapenemases belong to groups 1, group 2 2df, 2f and group 3 3a, 3b and 3c. The first cases of carbapenemase producing Klebsiella pneumoniae were reported in the United States in ; the first case of carbapenemase producing Klebsiella pneumoniae in Latin America Medellin - Colombia was reported inlater a case was reported in Chile in and in in Lima-Peru [6] what does mean contact precautions, [7].

Table 1 shows the integration between the classifications [5] of Ambler and Bush. Table 1. The objective of this case report is to discuss the rational use of antimicrobials, and the real need to treat asymptomatic urinary tract infections through the presentation of a clinical case. Even when the resistance phenotype tempts the physician to eliminate the microorganism, it must always be kept in mind that this could be part of a microbiota that colonizes the patient, so treating such colonization can lead to the expression of various mechanisms of resistance in microorganisms that naturally do not express them, and that do not cause illness.

A year-old male, from Huancayo — Peru, with a history of spinal cord injury associated with paraplegia, precautuons reason why he undergoes motor kinesiotherapy and uses a Foley catheter intermittently. In the what is congenital defects 5 years, the patient has presented five episodes of urinary tract infections, receiving in two episodes treatment with ciprofloxacin on an outpatient basis.

Later, the last three episodes of urinary tract infections have required hospitalization. Ceftriaxone was the treatment used in the first hospitalization and imipenem in the last two hospitalizations. In August 28,the patient was contaxt after having a urine culture result with development of Klebsiella pneumoniae resistant to carbapenems see table 2receiving in this opportunity antimicrobial treatment with imipenem until completing seven days, awaiting assessment by the Infectology team.

At the same time, contact precautions for the patient were established, in addition to the active search for inhospital and intra-domiciliary contacts. During the hospital period this pathogen was not isolated in any other sample 28 beds, wife and childand the patients who were in contact did not present any acute infection during their hospitalization. Months later, two control urine cultures were performed on the patient, with an interval of 15 days apart, showing the presence of the same microorganism and resistance phenotype as in previous stages, all these in the absence of urinary symptoms, this was a reason to consider this as a colonization.

Currently, one year after the strain was investigated, the patient is stable, does not what does mean contact precautions urinary symptoms and continues receiving motor kinesiotherapy for the sequelae of spinal cord injury. The strain of Klebsiella pneumoniae with phenotype of resistance to carbapenems was identified. Diagnostic confirmation of carbapenemase production was carried out through the Kirby Bauer method, according to the Comtact Laboratory Standards Institute standards and the manual of procedures for the phenotypic detection of resistance mechanisms of the Peruvian microbiology society Similarly, the Hodge phenotypic test was carried meaj.

Table 2. Carbapenemases what does mean contact precautions a group of enzymes which have the ability to hydrolyze what does mean contact precautions antibiotics. The carbapenemases of the type KPC Klebsiella pneumoniae carbapenemase belong to the class A of Ambler and group 2f of Bush; these enzymes are the most what does mean contact precautions isolated worldwide [5].

Factors for its acquisition include: immunosuppression, previous exposure to broad-spectrum antibiotics, presence of a urinary catheter and prolonged mexn in the intensive care unit [8][9]. Peru has been conducting epidemiological surveillance of antimicrobial resistance for six years [10]. Thus, in andthe first cases of carabapenemases were reported in the capital of our country Lima-Peru.

After these events, these resistance profiles have not been reported to what does mean contact precautions in other cities. Unfortunately, the two cases make a food chain with a producer and three consumers above were deadly, unlike this case, which represents a colonization by K.

Inthe Centers for Disease What does mean contact precautions and What does mean contact precautions CDC disseminated strategies for the control of infections caused by carbapenemase-producing enterobacteria. Taking as main points: the isolation of the index case, the implementation of detection protocols for carbapenemic resistant strains and the weekly monitoring of index case contacts [11].

Likewise, a study of patients colonized with by Klebsiella pneumoniae producing KPC carbapenemases reported that the establishment of contwct measures in hospitals of high prevalence decrease the incidence of this microorganism [12]. Another key point is to evaluate the colonization by carbapenemase producing Klebsiella pneumoniae. In the present case, the patient persists colonized contactt carbapenemase producing Klebsiella pneumoniae after one year.

Regarding the measures for the management of jean producing Klebisella pneumoniae infections, these are based on two main axes. First of all, it what does mean contact precautions essential to control and contain the index case, in order to reduce the transmissibility of the microorganism, these control measures consist of strict clinical hand washing, contact precautions and daily disinfection of the surfaces in the unit where the patient what does mean contact precautions located.

Considering that Klebsiella pneumoniae is part of the intestinal microbiota, some authors suggest the performance of routine rectal swabs [14] in order to detect early Klebsiella pneumoniae carriers with XDR resistance phenotypes, either beta-lactamase spectrum type extended ESBL or carbapenemase type KPC. It is important to keep in mind that carbapenemases produced by Klebsiella pneumoniae are plasmidial, so if the control measures are not established early, the risk of plasmidial transfer between different bacterial genera is high, being able to generate the same phenotype of resistance in other microorganisms.

Regarding the pharmacological management, once the strain has been detected, it must be assessed that this is not colonization. Subsequently, already defined that the microorganism is causing disease in prexautions patient, the recommended scheme consists of colistin polymyxin E associated with meropenem or imipenem, or the use of ceftazidime-avibactam [15].

Other authors have described total remission of Klebsiella pneumoniae infections in blood cultures with the use of high dose oral fosfomycin 9 g every every 8 hrs what is knowledge management system pdf with other antibiotics according to antibiogram, with negative blood cultures results after two days of started the scheme [16].

The use of fosfomycin monotherapy at high doses 8 g every precautikns hrs intravenously is another option too, resulting in negative cultures at 24 hours since the start of therapy [17]. As mentioned above, keeping in mind the pharmacokinetics of each antimicrobial [18] what does mean contact precautions, [19] is crucial in predicting the desired antibiotic concentration in different extravascular compartments.

The pharmacokinetic parameters of the antimicrobials indicated in Klebsiella pneumoniae KPC infection are presented in Table 3. Table 3. Pharmacokinetic parameters of antimicrobials [16] indicated for K. Regarding the impact on mortality associated with whwt pathogen, an associated mortality of There are no studies addressing mortality by KPC in our country, due to the low incidence reported.

In retrospective, detailing the clinical history, the irrational use of antimicrobials was found as risk factors for the acquisition of this strain, as well as the chronic use of intermittent catheterization by Foley catheter. No other data were obtained that contribute to the acquisition of a KPC strain. Unfortunately until now, our hospital does not have specific regulations for the management of these cases.

Our action responded to the alarming fact of isolating a multidrug-resistant germ and its probable repercussion within our hospital. The risk factors involved in the acquisition of carbapenemic-resistant strains in the present clinical case were the indiscriminate use of antimicrobials what does mean contact precautions previous hospitalizations together with the chronic use of intermittent Foley catheter.

Based what does mean contact precautions the information presented in the case, is a priority the creation of specific protocols for the management of cases of enterobacteria resistant to carbapenems, considering that these antimicrobials are the last line in the management of serious infections. Active surveillance by rectal swabs in hospitalized patients has given favorable results for the early detection of XDR resistance phenotypes, whether they are extended-spectrum beta-lactamases ESBLs such as KPC-type carbapenemase.

The use of colistin associated with meropenem or imipenem is indicated as long as the organism is causing disease, and is not part of the patient's microbiota as colonization. This translates into not initiating antimicrobial chemotherapy in patients with asymptomatic urinary tract infections. The use of fosfomycin in cases of Klebsiella pneumoniae infections resistant to carbapenems is shown as a good alternative when the first line schemes have been refractory.

The unnecessary taking of urine cultures tends to cause confusion regarding the management of patients with asymptomatic bacteriuria, tempting the clinician to indicate antimicrobial schemes whwt microorganisms that are part of the patient's microbiota, thus generating positive selection and the expression of mechanisms of resistance.
