ABSTRACT

A infecção do trato urinário (ITU) nada mais é do que o acometimento das vias urinárias por microrganismo. Entre as infecções hospitalares de maior incidência está a infecção do trato urinário, acometendo mais mulheres do que homens. Uma das possíveis causas dessa infecção, em pacientes na unidade de terapia intensiva (UTI), é o uso de cateter vesical. Seu tratamento inadequado pode ocasionar uma pielonefrite, podendo adentrar à circulação sanguínea, gerando uma infecção sistêmica e levar o paciente a óbito. A resistência antimicrobiana é uma das principais dificuldades encontrada em UTI sendo considerado um problema de saúde pública. O objetivo deste trabalho foi realizar um breve relato, baseado na literatura, sobre a resistência antimicrobiana na infecção urinária em unidade de terapia intensiva adulta. Em ambientes hospitalares o principal microrganismo causador de ITU é Escherichia coli, sendo 55,5% das culturas positivas estão associadas a procedimentos invasivos, como as sondas vesicais de demora, como consequência este é o microrganismo que mais apresenta resistência aos antimicrobianos utilizados como a ampicilina, trimetoprima e ciprofloxacino. O uso indiscriminado de antibióticos deixa em evidência a necessidade de análise criteriosa da real necessidade de qual antimicrobianos usar, tempo de uso e forma correta de administração. Portanto é necessária a ação dos profissionais de saúde frente a atenção ao paciente, desde a higiene das mãos, uso do cateter, quando necessário observar a real necessidade do uso do antimicrobianos e que esse seja feito após cultura e antibiograma.


Urinary tract infection (UTI) is nothing more than the involvement of the urinary tract by a microorganism. Among the hospital infections with the highest incidence is urinary tract infections, affecting more women than men. One of the possible causes of this infection in patients in the intensive care unit (ICU) is the use of a bladder catheter. Its inadequate treatment can cause pyelonephritis, which can enter the bloodstream, generating a systemic infection and leading the patient to death. Antimicrobial resistance is one of the main difficulties encountered in ICUs and is considered a public health problem. The objective of this study was to present a brief report, based on the literature, on antimicrobial resistance in urinary tract infections in an adult intensive care unit. In hospital environments, the main microorganism that causes UTI is Escherichia coli, and 55.5% of positive cultures are associated with invasive procedures, such as indwelling urinary catheters, as a consequence, this is the microorganism that is most resistant to antimicrobials used, such as ampicillin, trimethoprim and ciprofloxacin. The indiscriminate use of antibiotics highlights the need for a careful analysis of the real need for which antimicrobials to use, time of use, and correct form of administration. Therefore, it is necessary for the action of health professionals in the care of the patient, from the hygiene of the professional to, the use of the catheter, when necessary to observe the real need for the use of antimicrobials and that this is done after culture and antibiogram.


La infección del tracto urinario (ITU) no es más que la afectación de las vías urinarias por un microorganismo. Entre las infecciones hospitalarias con mayor incidencia se encuentra la infección del tracto urinario, que afecta más a mujeres que a hombres. Una de las posibles causas de esta infección en pacientes en la unidad de cuidados intensivos (UCI) es el uso de una sonda vesical. Su tratamiento inadecuado puede causar pielonefritis, la cual puede ingresar al torrente sanguíneo, generando una infección sistémica y llevando al paciente a la muerte. La resistencia a los antimicrobianos es una de las principales dificultades encontradas en las UCI y se considera un problema de salud pública. El objetivo de este estudio fue presentar un breve informe, basado en la literatura, sobre la resistencia antimicrobiana en infecciones del tracto urinario en una unidad de cuidados intensivos de adultos. En ambientes hospitalarios, el principal microorganismo causante de ITU es Escherichia coli, y el 55,5% de los cultivos positivos están asociados a procedimientos invasivos, como sondas vesicales permanentes, por lo que este es el microorganismo más resistente a los antimicrobianos utilizados, como la ampicilina. ., trimetoprima y ciprofloxacino. El uso indiscriminado de antibióticos pone de relieve la necesidad de un análisis cuidadoso de la necesidad real de qué antimicrobianos utilizar, el momento de uso y la forma correcta de administración. Por lo tanto, es necesaria la actuación de los profesionales de la salud en el cuidado del paciente, desde la higiene del profesional, uso del catéter, cuando sea necesario observar la necesidad real del uso de antimicrobianos y que este se realice previo cultivo y antibiograma.

ABSTRACT

Se expone el caso de un recién nacido que desarrolló sepsis connatal precoz a Streptococcus agalactiae, con meningitis aguda supurada y osteoartritis de rodilla izquierda. Como factor de riesgo la madre no tenía realizado el exudado rectovaginal, pesquisa que detecta la colonización por estreptococo del grupo B (EGB). Se aisló el germen en hemocultivo y en líquido de punción articular. Recibió tratamiento antibiótico adecuado a la sensibilidad del microorganismo y según pauta de sepsis con meningitis, evolucionando favorablemente. En este trabajo se describe la epidemiología de la sepsis neonatal y los cambios ocurridos luego de la implementación de la profilaxis antibiótica en el preparto.


We hereby present the case of a newborn with early connatal sepsis due to Streptococcus agalactiae, with acute suppurative meningitis and left knee osteoarthritis. As a risk factor, the mother had not performed the rectus vaginal exudate screening that detects colonization by Group B Streptococcus (GBS). The germ was isolated in blood culture and in joint puncture fluid. The patient received germ-sensitive antibiotic treatment for meningitis sepsis and evolved favorably. This paper describes the epidemiology of neonatal sepsis and the changes that have occurred after the administration of the antibiotic prophylaxis during pregnancy.

ABSTRACT

A endocardite de valva nativa é uma doença incomum, complexa, e de alta morbimortalidade. Requer tratamento clínico prolongado, com várias complicações possíveis, e o seu tratamento cirúrgico é complexo e tecnicamente difícil. O ecocardiograma transtorácico e transesofágico são fundamentais na avaliação da doença, inclusive seus achados são parte dos critérios diagnósticos de endocardite. Adicionalmente, o ecocardiograma tridimensional (3D) contribui com detalhamento anatômico na avaliação das estruturas cardíacas acometidas pela doença. Mostramos um caso em que é ilustrado o papel da ecocardiografia no diagnóstico e avaliação de complicações da endocardite, comparando as imagens do ecocardiograma 3D pré-operatórias, com os achados durante o ato cirúrgico. (AU)


Native valve bacterial endocarditis is an uncommon, complex, and highly morbid disease that requires prolonged clinical treatment and challenging surgical interventions. Transthoracic and transesophageal echocardiography are paramount assessment tools whose findings are included in the diagnostic criteria. Three-dimensional echocardiography shows further realistic imaging details. Here we present a case demonstrating the role of echocardiography in the diagnosis of endocarditis and the identification of its complications to show how advanced imaging techniques may have a remarkable resemblance with in vivo surgical findings.

ABSTRACT

Resumen Paciente de sexo femenino de 65 años, con antecedentes de hipertensión arterial crónica, resistencia a la insulina, histerectomía total y fractura tibioperonea antigua, es hospitalizada por cuadro febril, sin foco, de 2 meses de evolución, con sospecha de endocarditis por parámetros inflamatorios elevados y soplo diastólico en foco aórtico 2/6. Se estudia con ecocardiograma, transtorácico (ETT) y transesofágico (ETE), que muestra vegetación en velo aórtico coronario izquierdo de 9 mm por 7 mm e insuficiencia aórtica leve, motivo por el cual se toma hemocultivo resultando positivo para Rothia aeria. La paciente evoluciona con embolia de riñón derecho y bazo, y posteriormente, con hemorragia subaracnoidea. Inicia tratamiento antibiótico con ampicilina, vancomicina y gentamicina, con lo cual presenta una evolución satisfactoria y es dada de alta luego de 28 días de hospitalización. Al revisar la literatura, se puede llegar a la conclusión de que la endocarditis por Rothia es extremadamente infrecuente y que, en cuanto al cuadro clínico, tiene tendencia a una forma de presentación subaguda, con presencia de vegetaciones grandes mayores a 10mm y un alto grado de complicaciones neurológicas.


Abstract A 65-year-old female patient, with a history of chronic hypertension, insulin resistance, total histerectomy, and tibioperoneal fracture, is hospitalized for fever of unknown etiology. Basterial endocarditis was suspected due to elevated inflammatory parameters and a 2/6 diastolic murmur present in the aortic focus. Transthoracic and transesophageal echocardiography, showed a 9 mm by 7 mm vegetation in the left coronary aortic leaflet of and mild aortic insufficiency, Blood cultures were positive for Rothia aeria. She developed embolism of the right kidney and spleen, and subsequently, a subarachnoid hemorrhage. Antibiotic therapy was initiated with ampicillin, vancomycin and gentamicin, with a satisfactory evolution being discharged after 28 days of hospitalization. When reviewing the literature, it can be concluded that Rothia endocarditis is extremely rare and that, tends to have a subacute presentation with large vegetations, larger than 10 mm, and a high incidence of neurological complications.

Evoluciona favorablemente, es dado de alta al noveno día con diagnóstico de sepsis por Salmonella tipo D connatal. Coprocultivo de madre positivo para Salmonella. DISCUSIÓN: La prevalencia de infecciones por Salmonella se ha incrementado en neonatos. Es importante realizar prevención durante el embarazo además de un diagnóstico y tratamiento precoz. Se debe considerar este agente según factores de riesgo y como diagnóstico diferencial de hemorragia digestiva baja en el RN...


Salmonella infections are still a cause of entericdisease in Chile, with a predominance of the Enteritidis serotype. In neonatal sepsis the most frequent etiology is Group B Streptococcal (GBS) infection; enteric Gram-negative bacilli occupy second place. Salmonella spp. is infrequent. The transmission routes can be hematogenous, by birth canal, vertical, or horizontal. CASE REPORT: Healthy 31 year old female, 39 week pregnancy. Negative GBS culture. Presents with diarrhea the day before labor, with vaginal delivery, four hour dilation period,15 minute expulsion period, clear amniotic fluid, intra delivery temperature (T°) of 38.3°C. Male, adequate for gestational age newborn, Apgar 9/9, with rectal T° of 38.1°C at birth. During second day of life, presents green liquid stools with blood streaks, weight loss of 10.6 percent (367.82 gr), and rectal T° of 37.7°C. Patient is admitted to neonatology service, where he presents elevated C-Reactive Protein of 2.7 mg/dL.

ABSTRACT

Spontaneous bacterial peritonitis (SBP) is a life-threatening complication in patients with ascites caused by advanced liver disease. While gram negative bacteria, such as Escherichia coli and Klebsiella pneumonia are the common pathogens, Listeria monocytogenes has been recognized as a very rare pathogen. Empirical treatment with third generation cephalosporins does not provide adequate antibiotics coverage against L. monocytogenes. Diagnosis is often delayed as it requires confirmation from ascitic fluid culture. Herein, we describe the first case of SBP caused by L. monocytogenes in a patient with advanced alcoholic liver cirrhosis in Korea. Clinicians should be aware of the atypical pathogens, especially in patients with inadequate response to empirical antibiotics.

ABSTRACT

Listeria monocytogenes (L. monocytogenes) is an uncommon cause of bacterial meningitis in immunocompetent adults. Patients with immunosuppression are at increased risk of developing serious invasive diseases, particularly meningitis. We describe a case of meningitis caused by L. monocytogenes in an immunocompetent and previously healthy 34-year-old adult. The patient received treatment with intravenous ampicillin plus amikacin and made a full recovery. L. monocytogenes should be suspected in immunocompetent adults with bacterial meningitis who fail to respond to empirical antibiotic treatment.


Listeria monocytogenes (L. monocytogenes) é uma causa rara de meningite bacteriana em adultos imunocompetentes. Pacientes com imunossupressão têm maior risco de desenvolver graves doenças invasivas, especialmente a meningite. Descrevemos um caso de meningite por L. monocytogenes em um adulto imunocompetente e previamente sadio com idade de 34 anos. O paciente recebeu tratamento com ampicilina intravenosa mais amicacina e fez uma recuperação completa. L. monocytogenes deve ser suspeitada em imunocompetentes adultos com meningite bacteriana que não respondem ao tratamento antibiótico empírico.

ABSTRACT

Selective intestinal decontamination (SID) with norfloxacin has been widely used for the prophylaxis of spontaneous bacterial peritonitis (SBP) because of a high recurrence rate and preventive effect of SID for SBP. However, it does select resistant gut flora and may lead to SBP caused by unusual pathogens such as quinolone-resistant gram-negative bacilli or gram-positive cocci. Enterococcus hirae is known to cause infections mainly in animals, but is rarely encountered in humans. We report the first case of SBP by E. hirae in a cirrhotic patient who have previously received an oral administration of norfloxacin against SBP caused by Klebsiella pneumoniae and presented in septic shock.

ABSTRACT

Fusobacteria are anaerobic gram-negative, non-spore forming bacilli found in normal flora of the oral cavity, urogenital tract, and gastrointestinal tract. Fusobacterium nucleatum has been seldom reported as a cause of liver abscess, particularly in immunocompetent hosts. A 55-year-old man with frequent periodontal disease visited our hospital with intermittent fever and headache for 2 months. Abdominal CT scan revealed an 8.2x6 cm mass in the right hepatic lobe with central low density. Abscess culture revealed F. nucleatum as the causative organism. Percutaneous abscess drainage and intravenous administration of antibiotics for 4 weeks improved symptoms and decreased the abscess size. We report a rare case of liver abscess due to F. nucleatum in an immunocompetent man with periodontal disease.

ABSTRACT

Introducción: A la fecha no se ha publicado un estudio aleatorizado que soporte las recomendaciones de tratamiento combinado en neumonía de la comunidad (NAC). El objetivo de este ensayo piloto fue evaluar los efectos clínicos de la adición de un macrólidoa la terapia empírica en pacientes con NAC. Materiales y métodos: Se aleatorizaron sesenta y dos pacientes hospitalizados por NAC a recibir ampicilina/sulbactam IV más azitromicina oral (n=32) versus ampicilina/sulbactam IV más placebo (n=30) a doble ciego. El punto final principal fue la cura precoz, evaluada al 5to día, definida como alta médica antes del 5to día ó estabilización clínica sin necesidad de cambios terapéuticos. Los puntos finales secundarios fueronestadía hospitalaria, fallo terapéutico y mortalidad. Resultados: La cura precoz fue mayor en el grupo macrólidos (81% vs 53%) (p=0.02), con una reducción de riesgo relativa de 60% (95% CI: 10-82%), una reducción absoluta de riesgo de 28% (95% CI: 5-50%) y un número necesario a tratar de 3 pacientes (95%CI: 2-18). La estadía hospitalaria fue menor en el grupo macrólidos (6,5 ± 2,3 vs 8,5 ±4,5 días, p=0.027). No hubo diferencias en cuanto a fallo terapéutico (3 versus 6 pacientes) ni mortalidad entre ambos grupos. Conclusiones: En este estudio piloto, el uso de azitromicina oral en combinación conbetalactámicos se asoció a una mayor tasa de cura precoz y menor estadía hospitalaria, sugiriendo una resolución clínica acelerada de la neumonía.


Background and objectives: To date, no randomized trials support the recommendation of combination therapy for community-acquired pneumonia (CAP). The aim of the pilot study was to determine the clinical efficacy of the addition of a macrolide as part of anempirical therapy of patients with CAP.Methods: Sixty-two patients admitted for non-severe CAP were randomized into two double-blind groups: intravenous ampicillin/sulbactam plus oral azithromycin (n=32) versusintravenous ampicillin/sulbactam plus placebo (n=30). The primary end point was early cure, evaluated at 5th day, and defined as 1) discharge before 5th day; or 2) clinical stability without changes in the antibiotic therapy. The secondary end points were lengthof stay, treatment failure and mortality. Results: The early cure rate was higher in the macrolide group than in the placebo group (81% vs 53%) (p = 0.02), with a relative risk reduction of 60% (95% CI: 10 - 82%), anabsolute risk reduction of 28% (95% CI: 5 - 50%) and a needed number of 3 patients to be treated (95% CI: 2 - 18). The length of stay was shorter in the macrolide group (6.5 ±2.3 vs 8.5 ± 4.5 days, p = 0.027), and there were no differences in treatment failure (3 vs6 patients) or mortality. Conclusion: The use of oral azithromycin in combination with ampicillin/sulbactam wasassociated with a higher early cure rate and a shorter length of stay, suggesting an accelerated clinical resolution of CAP.

ABSTRACT

As infecções do trato urinário (ITU) são definidas como a presença de microrganismos no trato urinário, podendo se localizar desde a uretra até os rins. Dentre as doenças infecciosas, as ITU estão entre as mais comuns na prática clínica e acometem homens e mulheres em qualquer idade. O presente trabalho objetivou avaliar a ocorrência de ITU diagnosticadas no Laboratório da Universitário da URI - Campus Erechim/RS. Durante o período de outubro de 2006 a outubro de 2007 foram analisados os resultados de 195 uroculturas, onde foram identificados 36 casos de ITU. A identificação das bactérias foi realizada por métodos bioquímicos tradicionais e o antibiograma pelo método de disco-difusão. Pacientes do sexo feminino foram os mais acometidos (97,22%) Observou-se um predomínio de ITU em indivíduos com idade superior a 40 anos, totalizando 47,22% dos casos. A Escherichia coli foi o microrganismo mais frequente (80,55%). Os uropatógenos apresentaram maiores índices de susceptibilidade à Ofloxacina (94,11%) e maiores índices de resistência à Ampicilina (69,44%). O diagnóstico correto das ITU é extremamente importante, pois permite a aplicação de um tratamento adequado e uso prudente e racional dos antimicrobianos.

ABSTRACT

The epidemiology of acute pyelonephritis (APN) has changed with time. Therefore we investigated the current clinical characteristics of APN and the significance of proper surgical management for treatment of 1,026 APN patients in South Korea for the past 5 yr. The male-to-female ratio was about 1:8. The peak ages of female patients were 20s (21.3%) and over 60s (23.7%), while that of male was over 60s (38.1%). The occurrence of sepsis was 10.1%. Complicated APN patients were 35.4%. Ninety-four patients (9.2%) needed urological procedures. The duration of the flank pain and of the costovertebral angle tenderness in complicated APN patients was statistically significantly longer than that with simple APN patients (4.3 vs. 3.4 days, 4.4 vs. 4.0 days). If flank pain and costovertebral angle tenderness sustain over 4 days, proper radiologic studies should be performed immediately with the consideration of surgical procedure. Also the resistance to antibiotics was increasing. As the sensitivities to ampicillin (27.2%) and trimethoprim/sulfamethoxazole (44.7%) of Escherichia coli and Klebsiella pneumoniae were very low, it is necessary to take the careful choice of antibiotics into consideration.

ABSTRACT

Esse artigo objetivou avaliar a resistencia da Escherichia coli ao antibiotico ciprofloxacina a partir dos resultados de uroculturas e seus antibiogramas no municipio de Aracaju-SE, no ano de 2007. Para tal, utilizou-se os registros do setor de microbiologiade dois laboratorios ambulatoriais e um hospitalar. Foram executadas no periodo em estudo, 3.646 uroculturas, sendo 2.629 negativas e 1.017 positivas. Dentre as positivas (64,1%) foram para Escherichia coli, seguida de Enterobacter spp. (10,7%) Klebsiella spp. (10,1%), Staphylococcus spp. (7,3%), Proteus spp. (5,4%), Morganella spp. (1%), Serratia spp. (0,8%) e Pseudomonas spp. (0,7%). Jaos antibioticos utilizados nas uroculturas positivas foram: ciprofloxacina (98,9 %), ceftriaxona (97,5%), amicacina (95,3%), ampicilina (94,9%), ceftazidima (94,7%), nitrofurantoina (90,3%) e tobramicina (90,1%). Neste estudo a Escherichia coli mostrou uma resistencia de 21,3%. Mediante esse resultado sugere-se que, ao ser administrado ciprofloxacina para tratamento de infeccoes urinarias por Escherichia coli em Aracaju-SE, ele seja realizado com bastante parcimonia.


This article aimed to evaluate the resistance of the Escherichia coli to the ciprofloxacin antibiotic based on urine cultures results and antibiograms in Aracaju-SE of 2007. To reach this goal, records from the Microbiology sector of two ambulatory laboratories and one hospital laboratory were used. During this period of studies, 3.646 urine cultures were accomplished, of which 2.629 were negative and 1.017 were positive. The samples were positive for Escherichia coli (64,1%), followed by Enterobacter spp. (10,7%), Klebsiella spp. (10,1%), Staphylococcus spp (7,3%), Proteus spp. (5,4%), Morganella spp. (1%), Serratia spp. (0,8%) and Pseudomonas spp. (0,7%). The antibiotics used in positive urine cultures were ciprofloxacin (98,9%), ceftriaxone (97,5%), amikacin (95,3%), ampicilin (94,9%), ceftazidime (94,7%), nitrofurantoin (90,3%) and tobramycin (90,1%). In this study, Escherichia coli showed a resistance of 21,3%. These results suggest that the ciprofloxacin administration for treating urinary infections by Escherichia coli should bedone with frugality in Aracaju-SE.
