Utilidad de las tiras reactivas para el diagnóstico temprano de peritonitis bacteriana espontánea en pacientes cirróticos con ascitis / Usefulness of test strips for early diagnosis of spontaneous bacterial peritonitis in cirrhotic patients with ascites

Introducción: La peritonitis bacteriana espontánea requiere un diagnóstico temprano para el inicio de antibioticoterapia. El estudio diagnóstico ideal es el citoquímico del líquido ascítico, el cual puede ser costoso, demorado y de disponibilidad limitada en centros primarios de atención en salud. Objetivo: Evaluar la utilidad y precisión diagnóstica de las tiras reactivas Multistix 10SG para el diagnóstico de peritonitis bacteriana espontánea en pacientes cirróticos con ascitis. Materiales y métodos: Estudio observacional descriptivo de prueba diagnóstica en pacientes cirróticos con ascitis. Se determinó el conteo de leucocitos del líquido ascítico por la escala colorimétrica de la tira reactiva Multistix 10SG y se comparó con el gold standard para el diagnóstico (polimorfonucleares ≥ 250 células/mm³). Resultados: De 174 pacientes con ascitis (51,7% mujeres, promedio de edad 59 años) 30 fueron diagnosticados con peritonitis bacteriana espontánea. Con un punto de corte grado ++, la tira reactiva tuvo sensibilidad 73,3%, especificidad 96,5%, valor predictivo positivo 81,4%, valor predictivo negativo 94,5%, razón de probabilidad positiva 21,2 y razón de probabilidad negativa 0,27. Conclusiones: Las tiras reactivas tienen adecuada especificidad y valor predictivo negativo, siendo una herramienta de bajo costo, uso sencillo, rápida interpretación y fácil acceso, para apoyar la decisión de no iniciar antibiótico en pacientes con ascitis y sospecha de peritonitis bacteriana espontánea. Por su baja sensibilidad no reemplazan al estudio citoquímico como prueba de elección para el diagnóstico definitivo, pero si es útil para optimizar el abordaje inicial de estos pacientes.

Introduction: Spontaneous bacterial peritonitis requires an early diagnosis to start antibiotic therapy. The ideal diagnostic study is the cytochemical of ascites fluid, which can be expensive, delayed and of limited availability in primary health care centers. Objective: Evaluate the usefulness and diagnostic accuracy of Multistix 10SG test strips for the diagnosis of spontaneous bacterial peritonitis in cirrhotic patients with ascites. Materials and methods: Observational descriptive study of diagnostic test in cirrhotic patients with ascites. The leukocyte count of ascites fluid was determined by the colorimetric scale of the Multistix 10SG test strip and compared with the gold standard for diagnosis (polymorphonuclear ≥ 250 cells / mm³). Results: Of 174 patients with ascites (51.7% women, average age 59 years) 30 were diagnosed with spontaneous bacterial peritonitis. With a grade ++ cut-off point, the test strip had sensitivity 73.3%, specificity 96.5%, positive predictive value 81.4%, negative predictive value 94.5%, positive likelihood ratio 21.2 and negative likelihood ratio of 0.27. Conclusions: The test strips have adequate specificity and negative predictive value, being a low cost tool, simple use, quick interpretation and easy access, to support the decision not to start an antibiotic in patients with ascites and suspected spontaneous bacterial peritonitis. Due to their low sensitivity they do not replace the cytochemical study as the test of choice for the definitive diagnosis, but it is useful for optimizing the initial approach of these patients.

Predictores de infección y mortalidad en pacientes con cirrosis hepática en el hospital de alta complejidad Virgen de la Puerta de Trujillo, Perú / Predictors of infection and mortality in patients with liver cirrhosis in the high complexity hospital Virgen de la Puerta from Trujillo, Peru

Introducción: La cirrosis hepática descompensada por infecciones bacterianas es uno de los principales diagnósticos de admisión a hospitalización, teniendo en cuenta que el riesgo per se en ello es más alto que en pacientes no cirróticos, conllevando a cifras altas de mortalidad. Objetivo: El presente estudio buscó determinar los predictores de infección y mortalidad en pacientes con cirrosis hepática, así como las características epidemiológicas-clínicas de los pacientes con cirrosis. Materiales y métodos: De manera prospectiva se recolectaron los datos de los pacientes cirróticos hospitalizados en el servicio de Gastroenterología y Medicina interna del hospital de alta complejidad Virgen de la Puerta desde el 2015 a Junio del 2018. Resultados: El estudio incluyó 66 pacientes. La frecuencia de infección fue de 37,88%, siendo más frecuente la peritonitis bacteriana espontánea (21,2%) y la mortalidad total fue de 12,12%. Al realizar regresión logística binaria y curva ROC se obtuvieron como predictores de mortalidad, el valor de MELD >13,5 (p=0,003), TP >18,26 (p=0,003) y el estadio Child Pugh C (p=0,02, IC 95% EXP(B) 0,13-0,365). Las variables que predicen ausencia de mortalidad fueron un valor de plaquetas ≥ 74 500 /mm3 (p=0,01) y Sodio ≥133 mEq/l (p=0,019). Los predictores de infección, valor de MELD ≤14,5 (p=0,0004) y el nivel de sodio ≥134,5 mEq/l (AUC 0,696, p=0,028), para predecir ausencia de infección. Conclusiones: El MELD alto es un factor predictor tanto de mortalidad como de infección. El Child Pugh C y los valores de tiempo de Protrombina altos son predictores de mortalidad. El nivel de sodio normal es un predictor de ausencia de mortalidad e infección, así como el valor de plaquetas discretamente disminuido es predictor de ausencia de mortalidad.

Introduction: Liver cirrhosis decompensated due to bacterial infections is one of the main diagnoses of admission to hospitalization, taking into account that the risk per se in it is higher than in non-cirrhotic patients, leading to high mortality rates. Objective: The present study sought to determine the predictors of infection and mortality in patients with liver cirrhosis, as well as the epidemiological-clinical characteristics of patients with cirrhosis. Material and methods: Prospective data were collected from hospitalized cirrhotic patients in the Gastroenterology and Internal Medicine Service of the Hospital High Complexity "Virgen de la Puerta", from 2015 to June 2018. Results: The study included 66 patients. The infection frequency was of 37.88%, being more frequent the spontaneous bacterial peritonitis (21.2%) and the total mortality was of 12.12%. When performing binary logistic regression and ROC curve, the MELD value> 13.5 (p=0.003), TP >18.26 (p=0.003) and the Child Pugh C stage were obtained as predictors of mortality (p=0.02, IC 95% EXP(B) 0.13-0.365). The variables that predict absence of mortality were a platelet value ≥74 500 /mm3 (p=0.01) and sodium ≥133 (p=0.019). The predictors of infection, MELD value ≤14.5 (p=0.0004) and sodium level ≥134.5 (AUC 0.696, p=0.028), to predict absence of infection. Conclusions: High MELD is a predictor of both mortality and infection. Child Pugh C and high values of Prothrombin time are predictors of mortality. The normal sodium level is a predictor of absence of mortality and infection, as well as platelet values discreetly low are predictors of absence of mortality.

Fecal peritonitis in aging rat model. Therapeutic response to different antibiotic strategies

Abstract Purpose: To evaluate the response of aging rats with sepsis to two different antibiotic regimens. Methods: The study was conducted with 30 aging rats (18 month-old) with autologous feces peritonitis. The animals were divided into three groups: Group 0 received no therapeutic intervention (control), while Group 1 received a single dose of 40 mg/kg meropenem and Group 2 received a single dose of 20 mg/kg moxifloxacin. The intervention in both Groups was made 6 hours after induction of peritonitis. The animals were followed up to 15 days for evaluating morbidity and mortality. The weights at baseline were similar in all groups. Results: At the end of follow-up, weight loss was significantly greater (p=0.0045) in Group 0 (non-intervention controls). Culture from a blood sample at the end of follow-up was positive in all the animals in Group 0, in two animals in Group 1 and in four animals in Group 2. Morbidity/mortality was significantly higher in Group 0 compared to both Groups 1 and 2 (p=0.003) but the scores were not significantly different between Groups 1 and 2 (p=0.6967). Conclusion: Both antibiotic regimens rendered promising results for the treatment of fecal peritonitis.

Impacto das mudanças da microbiologia na peritonite bacteriana espontânea em três diferentes períodos ao longo de 17 anos / Impact of microbiological changes on spontaneous bacterial peritonitis in three different periods over 17 years

ABSTRACT BACKGROUND: Spontaneous bacterial peritonitis is a serious complication in cirrhotic patients, and changes in the microbiological characteristics reported in the last years are impacting the choice of antibiotic used for treatment. OBJECTIVE: The aim of the present study is to evaluate the changes in the epidemiology and bacterial resistance of the germs causing spontaneous bacterial peritonitis over three different periods over 17 years. METHODS: All cirrhotic patients with spontaneous bacterial peritonitis and positive culture of ascites fluid were retrospectively studied in a reference Hospital in Southern Brazil. Three periods were ramdomly evaluated: 1997-1998, 2002-2003 and 2014-2015. The most frequent infecting organisms and the sensitivity in vitro to antibiotics were registered. RESULTS: In the first period (1997-1998) there were 33 cases, the most common were: E. coli in 13 (36.11%), Staphylococcus coagulase-negative in 6 (16.66%), K. pneumoniae in 5 (13.88%), S. aureus in 4 (11.11%) and S. faecalis in 3 (8.33%). In the second period (2002-2003), there were 43 cases, the most frequent were: Staphylococus coagulase-negative in 16 (35.55%), S. aureus in 8 (17.77%), E. coli in 7 (15.55%) and K. pneumoniae in 3 (6.66%). In the third period (2014-2015) there were 58 cases (seven with two bacteria), the most frequent were: E. coli in 15 (23.1%), S. viridans in 12 (18.5%), K. pneumoniae in 10 (15.4%) and E. faecium 5 (7.7%). No one was using antibiotic prophylaxis. Considering all staphylococci, the prevalence increased to rates of the order of 50% in the second period, with a reduction in the third period evaluated. Likewise, the prevalence of resistant E. coli increased, reaching 14%. CONCLUSION: There was a modification of the bacterial population causing spontaneous bacterial peritonitis, with high frequency of gram-positive organisms, as well as an increase in the resistance to the traditionally recommended antibiotics. This study suggests a probable imminent inclusion of a drug against gram-positive organisms in the empiric treatment of spontaneous bacterial peritonitis.

RESUMO CONTEXTO: A peritonite bacteriana espontânea é uma complicação séria em pacientes cirróticos e as alterações nas características microbiológicas relatadas nos últimos anos podem afetar a escolha do antibiótico utilizado no tratamento. OBJETIVO: Os objetivos do presente estudo são avaliar as mudanças na epidemiologia e perfil de resistência bacteriana dos germes causadores de peritonite bacteriana espontânea em três períodos diferentes ao longo de 17 anos. MÉTODOS: Todos os pacientes cirróticos com peritonite bacteriana espontânea e cultura positiva de fluido ascítico foram estudados retrospectivamente em um hospital de referência no Sul do Brasil. Foram avaliados três diferentes períodos selecionados de forma randômica: 1997-1998, 2002-2003 e 2014-2015. Os organismos infecciosos mais frequentes e a sensibilidade in vitro a antibióticos foram registados. RESULTADOS: No primeiro período (1997-1998) houve 33 casos; os mais comuns foram: E. coli em 13 (36,1%), Staphylococcus coagulase-negativo em 6 (16,7%), K. pneumoniae em 5 (13,9%), S. aureus em 4 (11,1%) e S. faecalis em 3 (8,3%). No segundo período (2002-2003), houve 43 casos, os mais frequentes foram: Staphylococus coagulase-negativo em 16 (35,5%), S. aureus em 8 (17,8%), E. coli em 7 (15,5%) e K. pneumoniae em 3 (6,7%). No terceiro período (2014-2015), houve 58 casos (sete com duas bactérias), os mais frequentes foram: E. coli em 15 (23,1%), S. viridans em 12 (18,5%), K. pneumoniae em 10 (15,4%) e E. faecium 5 (7,7%). Nenhum paciente estava usando profilaxia antibiótica. Quando considerados todos os estafilococos, a prevalência aumentou para taxas da ordem de 50% no segundo período, apresentando redução no terceiro período avaliado. Do mesmo modo, a prevalência de E coli resistente aumentou, chegando a 14%. CONCLUSÃO: Houve modificação da população bacteriana causadora de peritonite bacteriana espontânea, com alta frequência de organismos gram-positivos, bem como aumento da resistência aos antibióticos tradicionalmente recomendados. Este estudo sugere uma provável inclusão iminente de um medicamento contra organismos gram-positivos no tratamento empírico da peritonite bacteriana espontânea.

Peritonitis bacteriana espontánea por Listeria monocytogenes en un paciente con cirrosis hepática: reporte de un caso / Spontaneous bacterial peritonitis due to Listeria monocytogenes in a patient with cirrhosis: case report

Spontaneous bacterial peritonitis (SBP) is a frequent and severe complication in cirrhotic patients. Listeria monocytogenes is a rare cause of SBP, which should be suspected in individuals with impaired immunity such as advanced liver disease and inadequate response to standard antibiotic therapy. We report a case of a 72 year-old patient with liver cirrhosis secondary to alcohol consumption, asymptomatic carrier of Hepatitis B virus, diabetes Type II and coronary artery disease; who is admitted with a diagnosis of hepatic encephalopathy and suspicion of spontaneous bacterial peritonitis receiving empiric antibiotic treatment with ceftriaxona. Initially he showed clinical response but a few days later he got worse. Ascitic culture confirmed infection by Listeria monocytogenes. Antibiotic treatment was adjusted but patient continued deteriorating progressively, and finally died due to renal dysfunction.

La peritonitis bacteriana espontánea (PBE) es una complicación frecuente y grave en los pacientes cirróticos. Listeria monocytogenes es una causa poco frecuente de PBE, que debe sospecharse en individuos con inmunidad alterada como es la enfermedad hepática avanzada y con respuesta inadecuada a terapia antibiótica habitual. Presentamos el caso de un paciente de 72 años con antecedentes de cirrosis hepática secundaria a consumo de alcohol, portador asintomático del virus de la Hepatitis B (VHB), diabético tipo II y cardiópata coronario. Se hospitaliza por encefalopatía hepática secundaria a PBE, recibe tratamiento antibiótico empírico con ceftriaxona con respuesta clínica inicial y deterioro posterior. Cultivo de líquido ascítico confirma infección por Listeria monocytogenes. Pese a ajuste de tratamiento antibiótico, continúa empeorando y finalmente fallece por disfunción renal.

Campylobacter jejuni: un agente infrecuente de peritonitis en un niño con diálisis peritoneal / Campylobacter jejuni: A rare agent in a child with peritoneal dialysis-related peritonitis

La peritonitis es un problema grave en los niños que reciben diálisis peritoneal. La bacteria Campylobacter jejuni es una causa infrecuente de peritonitis. Un niño de 10 años de edad con insuficiencia renal terminal causada por síndrome urémico hemolítico atípico ingresó a nuestro hospital con dolor abdominal y fiebre. El líquido de la diálisis peritoneal era turbio; en el examen microscópico se observaron leucocitos abundantes. Se inició tratamiento con cefepime intraperitoneal. En el cultivo del líquido peritoneal se aisló Campylobacter jejuni, por lo que se agregó claritromicina oral al tratamiento. Al finalizar el tratamiento, el resultado del cultivo del líquido peritoneal era negativo. Hasta donde sabemos, no se había informado previamente peritonitis por C. jejuni en niños. Conclusión. Si bien la peritonitis por C. jejuni es rara en los niños, debe considerarse como factor etiológico de la peritonitis.

Peritonitis is a serious problem in children receiving peritoneal dialysis. Campylobacter jejuni is an unusual cause of peritonitis. A 10-year-old boy who had end stage renal failure due to atypical hemolytic uremic syndrome was admitted to our hospital with abdominal pain and fever. Peritoneal dialysis fluid was cloudy and microscopic examination showed abundant leukocytes. Intraperitoneal cefepime treatment was started. Campylobacter jejuni was isolated from peritoneal dialysis fluid culture and oral clarithromycin was added to the treatment. At the end of therapy, peritoneal fluid culture was negative. To our knowledge, C. jejuni peritonitis was not reported in children previously. Conclusion : Although C. jejuni peritonitis is rarely encountered in children, it should be considered as an etiologic factor for peritonitis.

Peritonitis fúngica por Rhodotorula mucilaginosa en una paciente en diálisis peritoneal automatizada: revisión de la literatura / Fungal peritonitis due to Rhodotorula mucilaginosa in a patient with automated peritoneal dialysis: literature review

Fungal peritonitis is a major complication of peritoneal dialysis associated with high mortality. Most survivors have a high rate of abandonment of peritoneal dialysis. We report a case of fungal peritonitis due to an unusual agent. An 83 year-old woman, with a history of type 2 diabetes mellitus and multiple episodes of bacterial peritonitis associated to technical flaws in the implementation of automated peritoneal dialysis, was admitted due to abdominal pain and cloudy peritoneal fluid. Rhodotorula mucilaginosa was identified in the peritoneal fluid by MALDI-TOF. She was treated with catheter removal and oral posaconazole for 14 days showing clinical resolution and non-recurrence.

La peritonitis fúngica es una complicación mayor de la diálisis peritoneal, con una alta mortalidad asociada y la mayoría de los sobrevivientes presentan una alta tasa de abandono de diálisis peritoneal como terapia de reemplazo renal. Se presenta un caso de peritonitis fúngica por un agente infrecuente. Mujer de 83 años, diabética con múltiples episodios de peritonitis bacteriana asociada a fallas técnicas en la ejecución de diálisis peritoneal automatizada, ingresa por cuadro clínico de dolor abdominal y líquido peritoneal turbio. Se confirmó la presencia de Rhodotorula mucilaginosa en líquido peritoneal mediante MALDI-TOF. Fue tratada con retiro del catéter y posaconazol oral por 14 días, presentando una evolución favorable.

Complications Requiring Hospital Admission and Causes of In-Hospital Death over Time in Alcoholic and Nonalcoholic Cirrhosis Patients

BACKGROUND/AIMS: Data on the epidemiology of alcoholic cirrhosis, especially in Asian countries, are limited. We compared the temporal evolution of patterns of alcoholic and nonalcoholic cirrhosis over the last decade. METHODS: We retrospectively examined the inpatient datasets of five referral centers during 2002 and 2011. The study included patients who were admitted due to specific complications of liver cirrhosis. We compared the causes of hospital admissions and in-hospital deaths between patients with alcoholic and nonalcoholic cirrhosis. RESULTS: Among the included 2,799 hospitalizations (2,165 patients), 1,496 (1,143 patients) were from 2002, and 1,303 (1,022 patients) were from 2011. Over time, there was a reduction in the rate of hepatic encephalopathy (HE) as a cause of hospitalization and an increase in the rate of hepatocellular carcinoma. Deaths that were attributable to HE or spontaneous bacterial peritonitis (SBP) significantly decreased, whereas those due to hepatorenal syndrome (HRS) significantly increased over time in patients with alcoholic cirrhosis. However, in patients with nonalcoholic cirrhosis, hepatic failure and HRS remained the principal causes of in-hospital death during both time periods. CONCLUSIONS: The major causes of in-hospital deaths have evolved from acute cirrhotic complications, including HE or SBP to HRS in alcoholic cirrhosis, whereas those have remained unchanged in nonalcoholic cirrhosis during the last decade.

EVALUATION OF LEUKOCYTE ESTERASE REAGENT STRIPS TEST IN THE DIAGNOSIS OF SPONTANEOUS BACTERIAL PERITONITIS IN CHILDREN WITH CIRRHOSIS / Avaliação de tiras reagentes de teste de esterase de leucócitos no diagnóstico de peritonite bacteriana espontânea em crianças com cirrose

BackgroundSpontaneous bacterial peritonitis is defined as an ascetic fluid infection without an evident intra-abdominal surgically treatable source. Spontaneous bacterial peritonitis is one of the severe complications in patients with cirrhosis and ascites. Without early antibiotic treatment, this complication is associated with high mortality rate; therefore, early diagnosis and treatment of spontaneous bacterial peritonitis is necessary for survival. Leukocyte esterase reagent can rapidly diagnose the spontaneous bacterial peritonitis.ObjectiveThis study aimed to find out the diagnostic accuracy of leukocyte esterase dipstick test for the diagnosis of spontaneous bacterial peritonitis.MethodsA single centered hospital-based cross-sectional study was conducted during July 2013 to August 2014 on children with cirrhotic liver disease and ascites who were admitted in the Department of Pediatric Gastroenterology in Nemazee Hospital affiliated to Shiraz University of Medical Sciences (Iran). All patients underwent abdominal paracentesis, and the ascitic fluid was processed for cell count, leukocyte esterase reagent strip test (Combiscreen SL10) and culture. Spontaneous bacterial peritonitis was defined as having a polymorphonuclear count (PMN ≥250/m3) in ascitic fluid. Sensitivity, specificity, positive predictive value and negative predictive value of leukocyte esterase test were calculated according to the formula.ResultsTotally, 150 ascitic fluid sample of cirrhotic male patients (53.2%) and their mean age (4.33±1.88 years) were analyzed. Biliary atresia (n=44, 29.4%) and idiopathic neonatal hepatitis (n=29, 19.3%) were the most frequent etiology of cirrhosis. Also, abdominal pain (68.6%) and distension (64%) were the most common presenting complaint. Of all cases, 41patients (27.35%) were diagnosed to have spontaneous bacterial peritonitis (PMN ≥250/mm3). Sensitivity and specificity of leukocyte esterase reagent test according to PMNs ≥250mm3 were 87.80% and 91.74%, also on ascitic fluid culture results were 88.23% and 77.44%. Positive predictive value and negative predictive value of this test in PMNs ≥250mm3 were 80% and 95.23% and in cases with positive culture 33.33% and 98.09% were obtained, respectively. Efficiency of leukocyte esterase reagent test in diagnosing spontaneous bacterial peritonitis, according to PMNs ≥250mm3 and culture results were 90.66% and 78.66%.ConclusionThe leukocyte esterase strip test may be used as rapid test for diagnosis of spontaneous bacterial peritonitis due to its high diagnostic validity.

ContextoA peritonite bacteriana espontânea é definida como uma infecção do fluido ascítico sem evidente origem intra-abdominal cirurgicamente tratável. A peritonite bacteriana espontânea é uma das complicações graves em pacientes com cirrose e ascite. Sem tratamento antibiótico precoce, esta complicação é associada com alta taxa de mortalidade. Portanto, o diagnóstico precoce e tratamento de peritonite bacteriana espontânea são necessários para a sobrevivência. O reagente de esterase de leucócitos pode rapidamente diagnosticar a peritonite bacteriana espontânea.ObjetivoEste estudo teve como objetivo descobrir a acurácia diagnóstica do teste com tiras de esterase de leucócitos para o diagnóstico de peritonite bacteriana espontânea.MétodosUm estudo transversal hospitalar unicêntrico foi realizado entre julho de 2013 e agosto de 2014 em crianças com cirrose hepática e ascite que foram admitidas no Departamento de Gastroenterologia Pediátrica no Hospital de Nemazee afiliado à Universidade de Ciencias Médicas de Shiraz (Irã). Todos os pacientes foram submetidos a paracentese abdominal, e o líquido ascítico foi processado para contagem de células, teste de tira de reagente de esterase de leucócitos (Combiscreen SL10) e cultura. Peritonite bacteriana espontânea foi definida como tendo uma contagem de polimorfonucleares (PMN ≥250/m3) no líquido ascítico. Sensibilidade, especificidade, valor preditivo positivo negativo do teste de esterase de leucócitos foram calculados de acordo com a fórmula.ResultadosForam analisados um total de 150 amostras de líquido ascítico de pacientes cirróticos; (53,2%) eram do sexo masculino e sua média de idade (4,33±1,88 anos). A atresia biliar (n=44, 29,4%) e hepatite neonatal idiopática (n=29, 19,3%) foram as etiologias mais frequentes de cirrose. Além disso, dor abdominal (68,6%) e distensão (64%) foram as queixas mais comuns de apresentação. De todos os casos, 41 (27,35%) foram diagnosticados com peritonite bacteriana espontânea (PMN ≥250/mm3). A sensibilidade e especificidade do teste de reagente de esterase de leucócitos segundo PMN ≥250mm3 foi de 87,80% e 91,74% e, para os resultados de cultura de líquido ascítico, de 88,23% e 77,44%. Valor preditivo positivo e valor preditivo negativo do teste em PMN ≥250mm3 foi de 80% e 95,23% e em casos com cultura positiva 33,33% e 98,09%, respectivamente. A eficiência do teste de reagente esterase de leucócitos no diagnóstico de peritonite bacteriana espontânea, de acordo com resultados de ≥250mm3 e cultura PMN, foi de 90,66% e 78,66%.ConclusãoO teste de tiras de esterase de leucócitos pode ser usado como um teste rápido para diagnóstico de peritonite bacteriana espontânea, devido a sua alta validade diagnóstica.

Devido à mudança do perfil microbiológico, percebe-se a necessidade de uma instituição analisar o seu perfil microbiológico, para melhor assistência aos seus usuários (AU)

Introduction: Spontaneous bacterial peritonitis (SBP) is one of the most common infections in cirrhotic patients, leading to high morbidity and mortality. Methods: Cross-sectional, retrospective, descriptive study. A review of records of ascites fluid with positive culture for SBP was carried out. Results: Gram-negative bacilli constituted 57.1% positive cultures, and E. coli accounted for 28.5%, followed by Klebsiella sp (14.2%). Gram positive cocci accounted for 38%, and of these the most frequent ones were Enterococcus sp. (23.8%) and Streptococcus sp. (9.5%). Conclusion: The sample showed a higher prevalence of enterococci as compared with what is described in world literature. Due to the change in the microbiological profile, we highlight the need for an institution to analyze its microbiological profile, for better assistance to its members (AU)

Evaluación de la realización de paracentesis en pacientes cirróticos ingresados a dos servicios de medicina interna de hospitales mediana complejidad / Assessment of the fulfillment of paracentesis in cirrotic patients admited in two services of internal medicine in hospitals of median complexity

La peritonitis bacteriana espontánea (PBE) es una complicación severa de la cirrosis hepática (CH). Su pronóstico depende del momento de inicio de la terapia para lo que se requiere un diagnóstico oportuno. Objetivo: Evaluar la realización de paracentesis diagnóstica (PD) en cirróticos con ascitis durante su hospitalización. Materiales y métodos: Estudio observacional, analítico y prospectivo, realizado en un período de 11 meses consecutivos. Resultados: Se registraron 92 ingresos, el promedio de edad fue de 60,3 años (DE 11,7), correspondiendo un 57,6% a hombres, la etiología de CH más frecuente fue alcohólica (48,9%). Se realizaron 40 PD (43,5%), de ellas 35% con PBE positiva. Del total de PD, un 47,5% se efectuaron al ingreso y/o al presentar signos de alarma. El promedio de días de hospitalización fue mayor en aquellos en que se realizó la PD tardíamente. El MELD (Model for the End stage Liver Disease) tanto al ingreso como egreso es significativamente mayor en los pacientes puncionados al ingreso. Conclusión: Se realiza PD en menos de la mitad de los cirróticos hospitalizados, siendo su realización oportuna solo en 1 de cada 5 de los ingresos. El realizar PD en el momento adecuado disminuye los días de hospitalización y morbimortalidad.

The Spontaneous Bacterial Peritonitis (SBP) is a severe complication of cirrhosis. The prognosis depends on the time of initiation of therapy that is required for early diagnosis. Objective: To evaluate the performance of diagnostic paracentesis (DP) in cirrhotic patients with ascites during hospitalization. Materials and methods: An observational, analytical, prospective, study conducted during October 2009 to June 2010. Results: There were 92 income, average age was 60.3 years (SD 11.7), corresponding to 57.6% men, the most common etiology of CH was alcohol (48.9%). There were 40 PD (43.5%), of which 35% positive SBP. Of the DP, 47.5% were performed on admission and / or submission of warning signs. The average period of hospitalization was higher in those who underwent late DP. The MELD score both at admission and discharge was significantly higher in patients on admission punctured. Conclusion: DP was done in less than half of hospitalized cirrhotic, and its timely completion only 1 in 5 of revenues. The DP perform at the right time reduces hospital days.

Accuracy of reagent strips in rapid diagnosis of spontaneous bacterial peritonitis

The objective of this study was to evaluate the accuracy of reagent strips for diagnosis of spontaneous bacterial peritonitis [SBP] in cirrhotic patients with ascites, taking polymorphonuclear cell count in ascetic fluid as standard criterion. One hundred and fifty patients having cirrhosis of liver and suspicion of SBP admitted in the medical ward of Services Hospital, Lahore were included in the study. Ascetic fluid of the patients was tested in the hospital laboratory for polymorph nuclear cell count and at the same time leukocyte esterase activity of the fluid was assessed by reagent strips. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of reagent strips were calculated. Frequency of SBP in cirrhotic patients with ascites was 28.67%. Specificity, sensitivity, positive predictive value, negative predictive value and diagnostic accuracy of reagent strips for diagnosis of SBP in cirrhotic patients with ascites, taking PMN cell count in ascetic fluid as standard criterion was calculated as 93.02%, 94.39%,86.97%,97.12% and 94% respectively. In view of the results of the current study reagent strip method can be recommended as a rapid and accurate method for diagnosis of SBP in cirrhotic patients

Peritonitis bacteriana espontánea asociada a bacteriemia por Vibrio cholerae no O1, no O139 / Spontaneous bacterial peritonitis associated with Vibrio cholerae non-O1, non-139 bacteremia

Vibrio cholerae is a Gram-negative bacilli with curved, comma shape that belongs to the family Vibrionaceae. The antigenic structure consists of a flagellar H antigen and a somatic O antigen (used to classify V cholerae in various serogroups). Serogroups 01 and 0139 have caused epidemics of cholera. Vibrio cholerae non-01 non-139 has been isolated from patients with bacteremia, acute secretory diarrhea, dysentery, abdominal pain, nausea, vomiting, fever and cellulitis. Invasive forms such as meningitis, spontaneous bacterial peritonitis (SBP) and encephalitis are uncommon. Immunosuppression and cirrhosis are risk factors for developing invasive disease. This case report describes a cirrhotic patient from Salta, Argentina, consulting for abdominal pain and fever. He was diagnosed with SBP and Vibrio cholerae non-01 non-139 bacteremia. He received antibiotic treatment with third generation cephalosporins for fourteen days with favorable clinical outcome.

Vibrio cholerae es un bacilo gramnegativo, curvo y móvil, perteneciente a la familia Vibrionaceae, que presenta antígenos flagelares H y somático O; este último permite clasificarlo en numerosos serogrupos. Los serogrupos O1 y O139 han causado epidemias de cólera. Vibrio cholerae serogrupo no O1, no O139 es no aglutinable con el antisuero específico y se manifiesta clínicamente como bacteriemias, diarrea acuosa, disentería, dolor abdominal, náuseas, vómitos, fiebre y celulitis. Raramente se describen formas invasoras tales como meningitis, peritonitis bacteriana espontánea (PBE) y cerebritis, entre otras. Dentro de los factores de riesgo para desarrollar enfermedad invasora se encuentran la inmunodepresión y la cirrosis hepática. Comunicamos el caso de un paciente procedente de la provincia de Salta, Argentina, con antecedentes de cirrosis hepática, que consulta por dolor abdominal y fiebre, en el que se diagnóstica PBE asociada a bacteriemia por Vibrio cholerae no 01, no 0139. Recibió tratamiento con cefalosporinas de tercera generación iv, por catorce días con una evolución clínica favorable.
