ABSTRACT

Invasive aspergillosis (IA) is associated with a high mortality rate in kidney-transplant recipients. Azole-resistance is increasing in Aspergillus fumigatus. We report a clinical case of a kidney-transplant recipient with cerebellar and pulmonary aspergillosis caused by azole-resistant Aspergillus parafelis (molecular identification through ß-tubulin sequence). The patient experienced an effective resolution after three surgical procedures and associated antifungal therapy. This case highlights that azole-resistant aspergillosis should be considered in every patient with IA as long as susceptibility testing results are not known. Therefore, in selected patients with IA and central nervous system involvement, empirical combination antifungal therapy could be considered.

ABSTRACT

Introducción. Los Staphylococcus coagulasa negativos(SCN) se han convertido en uno de los patógenos nosocomialesmás frecuentes y con una elevada tasa de mortalidad, debido ala mayor supervivencia de enfermos graves, estados deinmunosupresión prolongados y presencia de materialesextraños, como catéteres, prótesis, marcapasos, etc. Además,existe un importante aumento en las resistencias frente a losantimicrobianos, sobre todo betalactámicos, y se hadocumentado cómo el incremento en la CMI para vancomicinaconlleva una pérdida de su eficacia clínica, por lo que se buscannuevas alternativas terapéuticas, como daptomicina.El objetivo de este trabajo es estudiar la actividad dedaptomicina, ciprofloxacino, clindamicina y cotrimoxazol endos grupos de SCN clínicamente significativos, uno con CMI90para vancomicina ≤ 1 mg/L y el otro con CMI90 de 2 mg/L.Métodos. Se identificaron y estudiaron las CMI90 paraciprofloxacino, clindamicina y cotrimoxazol de 54 cepas de SCNclínicamente significativos mediante los paneles combo 22 deMicroScan (Dade behring, Siemens). La CMI90 para daptomicinase realizó mediante Etest (AB BioMèrieux, Solna, Suecia) enplacas de Mueller Hinton (BioMèrieux, Francia).Resultados. En el Grupo I (CMI90 para vancomicina ≤ 1mg/L) se estudiaron 19 cepas y en el Grupo II (CMI90 paravancomicina = 2 mg/L) se estudiaron 35 cepas. Expresadas enmg/L, los rangos de CMI90 para daptomicina fueron 0.047-0.5en el Grupo I y 0,064-0,5 en el Grupo II. Para ciprofloxacinohubo 8 cepas sensibles y 11 resistentes en el Grupo I y 10sensibles y 25 resistentes en el Grupo II. Para clindamicina hubo7 cepas sensibles y 12 resistentes en el Grupo I y 16 sensibles y19 resistentes en el Grupo II. Finalmente, Para cotrimoxazolhubo 10 cepas sensibles y 9 resistentes en el Grupo I y 19sensibles y 16 resistentes en el Grupo II...(AU)


Introduction. Coagulase Negative Staphylococci (CNS)have become one of the most common nosocomial pathogensand it has a high mortality rate due to the increased ofseriously ill patients survival, long states immunosuppressionand presence of foreign bodies, such as catheters, prostheses,pacemakers, etc. In addition, there is a significant increase inresistance to antimicrobial drugs, especially beta-lactams, andthe increase in the MIC for vancomycin leads to a loss ofclinical efficacy. This necessitates the search for newtherapeutic alternatives, such as daptomycin.The aim of this paper is to study the activity ofdaptomycin, ciprofloxacin, clindamycin and cotrimoxazole intwo groups of clinically significant CNS. a MIC90 withvancomycin ≤ 1 mg/L and the other with MIC90 2 mg/L.Methods. We identified and studied MIC90 tociprofloxacin, clindamycin and cotrimoxazole from 54 strainsof clinically significant by the CNS Combo 22 Microscan panels(Dade Behring, Siemens). The MIC90 for daptomycin wasperformed using Etest (AB BioMérieux, Solna, Sweden) onMueller Hinton plates (BioMérieux, France).Results In Group I (vancomycin MIC90 ≤ 1 mg/L) were 19 strains whereas in Group II (vancomycin MIC90 = 2 mg/L) were35 strains. Expressed in mg/L, MIC90 ranges for daptomycinwere 0.047-0.5 in Group I and 0.064-0.5 in Group II. Forciprofloxacin were 8 sensitive strains and 11 resistant in GroupI and 10 sensitive and 25 resistant in Group II. For clindamycinwere 7 sensitive strains and 12 resistant in Group I and 16sensitive and 19 resistant in Group II. Finally, for cotrimoxazolewere 10 sensitive strains and 9 resistant in Group I and 19sensitive and 16 resistant in Group II...(AU)

ABSTRACT

Objetivo. Se estudia la posibilidad de que la medición en líquido cefalorraquídeo de la proteína ß-traza y la cistatina C pueda resultar de utilidad para discriminar la existencia o la ausencia de meningitis bacteriana, comparada con la medida de los siguientes componentes del líquido cefalorraquídeo: glucosa, proteínas, recuento de leucocitos polimorfonucleares, enolasa neuronal específica, adenosina deaminasa y proteína C reactiva, usando como procedimiento de medida de referencia la tinción de Gram y el cultivo bacteriano positivos. Material y método. Se analizaron 73 muestras, dividiéndolas en varios grupos según su condición clínica: grupo control, grupo de meningitis bacteriana y un tercer grupo en el que se incluyeron diferentes enfermedades neurológicas, incluidas 4 meningitis virales. Resultados. Se comparó el grupo control frente al grupo de meningitis bacteriana y frente al grupo de diferentes enfermedades neurológicas, y los grupos de meningitis bacteriana y de diferentes enfermedades neurológicas entre sí, y se encontraron diferencias significativas en todos los casos. Se realizó, también, un algoritmo diagnóstico para diferenciar la meningitis bacteriana del resto de grupos usando la medida de la glucosa, la proteína ß-traza, la cistatina C y los leucocitos polimorfonucleares. Conclusiones. A pesar del escaso número de casos de meningitis bacteriana, la cistatina C y la proteína ß-traza podrían ser buenos indicadores para discriminar la etiología bacteriana de la meningitis(AU)


Objective. We studied the possibility that the laboratory tests ß-trace protein and cystatin C in cerebrospinal fluid could discriminate the existence or absence of a bacterial meningitis, compared to other tests such as glucose, protein, polymorphonuclear leukocytes count, neuron-specific enolase, adenosine deaminase and C-reactive protein, using Gram staining and bacterial cultures as reference techniques. Material and method. We analyzed 73 cerebrospinal fluid samples, divided into 3 groups: control group, bacterial meningitis group, and a third group of other diseases with neurological repercussions, including viral meningitis. Results. The control group was compared against the bacterial meningitis group and the group of diverse diseases, and the last 2 were both compared. Significant differences were observed between the bacterial meningitis group and the control group. Furthermore, a diagnosis algorithm was developed to differentiate bacterial meningitis from the other groups, based on the levels of glucose, ß-trace protein, cystatin C and the polymorphonuclear leukocytes count. Conclusions. Despite the small number of bacterial meningitis cases included, this study suggests that‚ ß-trace protein and cystatin C could be good laboratory tests in order to discriminate a bacterial aetiology(AU)
