Cierre primario de la herida operatoria versus cierre diferido en pacientes con peritonitis apendicular generalizada. Ensayo clínico con asignación aleatoria / Primary versus delayed closure of surgical wound in patients with generalized appendicular peritonitis. Randomized controlled trial

Introducción: La infección del sitio operatorio (ISO), es una de las principales complicaciones en la cirugía de la peritonitis generalizada por apendicitis aguda (PGAA). La mejor opción entre cierre primario (CP) y diferido (CD) de la laparotomía, aún es materia de controversia. El objetivo de este estudio fue determinar asociación entre tipo de cierre y desarrollo de ISO en pacientes con PGAA. Material y método: Ensayo clínico con asignación aleatoria (ECA) Se reclutó a pacientes con PGAA sin exclusión de sexo ni edad, e intervenidos quirúrgicamente en el Servicio de Cirugía del Hospital Obrero Nº 1 (La Paz, Bolivia) entre julio de 2019 y noviembre de 2021; y se les asignó de forma aleatoria a CP y CD; con un seguimiento mínimo de 30 días postoperatorio. Se aplicó estadística descriptiva (cálculo de porcentajes, de medidas de tendencia central y de dispersión); y posteriormente, se aplicaron estadísticas analíticas para estudiar asociación entre variables (test exacto de Fisher para variables categóricas y t de student para variables continuas). Se determinaron RA, RR, OR NNT y sus respectivos IC95%. Resultados: Se incluyeron 100 pacientes, divididos en 59 con CP y 41 con CD, con promedio de edad, peso, estatura e IMC de 43±13,1 años, 71±8,5 kilogramos, 1,61±0,8 metros y 27,6±3,2 respectivamente. La ISO fue de 29,8% y 4,7% en los grupos de CP y CD respectivamente. La incidencia de ISO para el CD fue de 0,05 (5%) y de 0,30 (30%) para el CP. Para los seromas, el RA para el CD es de 0,27 y para el CP de 0,55. El Número Necesario a Tratar (NNT) fue 3,97 (IC95%: 2,75-5,19). No hubo mortalidad. Conclusión: El CD se asocia a menor incidencia de ISO.

Introduction: Surgical site infection (SSI) is one of the main complications in surgery for generalized peritonitis due to acute appendicitis (GPAA). The best option between primary (PC) and delayed (CD) laparotomy closure is still a matter of controversy. The objective of this study was to determine the association between the type of closure and the development of SSI in patients with GPAA. Material and method: Randomized Clinical trial. Patients with GPAA were recruited without exclusion of sex or age, and underwent surgery in the Surgery Service of Hospital Obrero No. 1 (La Paz, Bolivia) between July 2019 and November 2021; they were randomly assigned to PC and DC; with a minimum follow-up of 30 days postoperatively. Descriptive statistics were applied (calculation of percentages, measures of central tendency, and dispersion); and subsequently, analytical statistics were applied to study the association between variables (Fisher's exact test for categorical variables and Student's T test for continuous variables). AR, RR, OR, NNT and their respective 95% CI were determined. Results: 100 patients were included, divided into 59 with PC and 41 with CD, with average age, weight, height, and BMI of 43±13.1 years, 71±8.5 kilograms, 1.61±0.8 meters and 27.6±3.2 respectively. The SSI was 29.8% and 4.7% in the PC and DC groups respectively. The incidence of SSI for DC was 0.05 (5%) and 0.30 (30%) for PC. For seromas, the AR for DC is 0.27 and for PC 0.55. The Number Needed to Treat (NNT) was 3.97 (95% CI: 2.75-5.19). There was no mortality. Conclusion: DC is associated with a lower incidence of SSI.

Epidemiología, resistencia antimicrobiana y tratamiento antibiótico empírico en peritonitis secundarias de la comunidad en un centro de la prov. de Buenos Aires / Epidemiology and review of antibiotic treatment in secondary community peritonitis in a province Buenos Aires's center

Las peritonitis secundarias constituyen una causa frecuente de internación y de uso de antibioticoterapia dentro de las infecciones intraabdominales. Realizamos un estudio retrospectivo, descriptivo y observacional de centro único desde enero a diciembre de 2021. El objetivo del estudio fue conocer la epidemiología local y adecuar el tratamiento empírico de las peritonitis secundarias de la comunidad. Se incluyeron pacientes mayores a 16 años con peritonitis secundaria, intervención quirúrgica, envío de material a cultivo y desarrollo microbiano de bacterias aerobias a través de la revisión de historias clínicas. Se analizaron cultivos de 36 pacientes, 64% de sexo masculino con una media de edad de 48,8 años. El 22% requirió internación en unidad de cuidados intensivos. La principal causa fue apendicitis aguda en el 61%, seguido por perforación secundaria a tumores. Se aislaron 43 bacterias aerobias (1,2 bacterias por episodio) siendo E. coli el microorganismo más frecuente. En la institución se utiliza piperacilina-tazobactam como tratamiento empírico. De acuerdo a las recomendaciones de la Sociedad Argentina de Infectología de 2018, en infecciones no complicadas podría utilizarse aminoglucósidos + metronidazol, optando por piperacilina-tazobactam en casos graves. No es recomendado como tratamiento empírico el uso de ampicilina-sulbactam y ciprofloxacina para infecciones graves o con difícil control del foco por la alta tasa de resistencia. En base a nuestro estudio podemos concluir que la epidemiología de los pacientes coincide con lo descrito en publicaciones nacionales, lo que nos lleva a reconsiderar el tratamiento empírico en casos leves, pudiendo optar por aminoglucósidos + metronidazol.

Secondary peritonitis is a frequent cause of hospital admission and an usual cause of use of antibiotic therapy in abdominal infections. We did a retrospective and observational study in one health center between January 2021 and December 2021. The aim of the study was to analyze the local epidemiology and adapt antibiotic empirical therapy of secondary community peritonitis. Patients aged 16 years and older with secondary peritonitis were included in this study. These patients needed surgical intervention and they had a positive culture with aerobic microorganism. We analyzed abdominal cultures from 36 patients, 64% men with a median age of 48.8 years. Twenty- two percent of these patients were admitted to intensive care unit. Acute appendicitis was the principal cause of secondary peritonitis in 61% of cases, followed by tumors. We found 43 aerobic bacterias (1.2 bacteria/episode), E.coli was the most frequent microorganism. In our hospital we use piperacillin- tazobactam for empirical treatment. According to the 2018 recommendations from the Argentine Society of Infectious Diseases, aminoglycosides + metronidazole can be used for uncomplicated intra-abdominal infections, and piperacillin-tazobactam should be used only in severe cases. However, ampicillin-sulbactam or ciprofloxacin is not recommended for severe cases or complicated infections due to the high resistance rates. Based on the finding of the study, it could be said that the epidemiology of the patients coincides with what was described in other national medical journals. Therefore, we should reconsider the use of aminoglycosides + metronidazole as empirical treatment for mild cases.

Etiological diagnostic value of metagenomic next-generation sequencing in peritoneal dialysis-related peritonitis / 中华肝脏病杂志

Objective: To explore the etiological diagnostic value of metagenomic next-generation sequencing (mNGS) in peritoneal dialysis (PD)-related peritonitis. Methods: The study was a retrospective cohort study. The clinical data of patients with PD-related peritonitis who were treated and underwent microbial cultivation and mNGS test at the same time from June 2020 to July 2021 in the Affiliated Drum Tower Hospital, Medical School of Nanjing University were analyzed. The positive rate, detection time and consistency between mNGS test and traditional microbial culture were compared. Results: A total of 18 patients with age of (50.4±15.4) years old and median dialysis time of 34.0 (12.4, 62.0) months were enrolled in the study, including 11 males and 7 females. Pathogenic microorganisms were isolated in 17 patients by mNGS test, with a positive rate of 17/18, which was higher than 13/18 of microbial culture, but the difference was not statistically significant (P=0.219). Both mNGS test and microbial culture isolated positive pathogenic bacteria in 12 patients, and mNGS test isolated the same types of pathogenic bacteria as microbial cultivation did in 11 patients. In five patients with negative microbial culture, mNGS test also isolated pathogenic microorganisms, including 3 cases of Staphylococcus epidermidis, 1 case of Mycobacterium tuberculosis and 1 case of Ureaplasma urealyticum. In 1 patient, microbial culture isolated pathogenic bacteria (Escherichia coli) whereas mNGS test did not. The detection time of mNGS was 25.0 (24.0, 27.0) h, which was significantly shorter than 89.0 (72.8, 122.0) h of microbial culture (Z=3.726, P<0.001). Conclusions: mNGS test can improve the detection rate of pathogenic microorganisms in PD-related peritonitis and greatly shorten the detection time, and has good consistency with microbial culture. mNGS may provide a new approach for pathogen identification of PD-related peritonitis, especially refractory peritonitis.

Clinical Outcome and Risk Factors of Treatment Failure of Peritoneal Dialysis Associated Peritonitis Caused by Klebsiella Pneumoniae:A Multicenter Study / 中国医学科学院学报

Objective To investigate the treatment outcomes,prognosis,and risk factors of treatment failure of peritoneal dialysis associated peritonitis (PDAP) caused by Klebsiella pneumoniae,and thus provide clinical evidence for the prevention and treatment of this disease. Methods The clinical data of PDAP patients at four peritoneal dialysis centers from January 1,2014 to December 31,2019 were collected retrospectively.The treatment outcomes and prognosis were compared between the patients with PDAP caused by Klebsiella.pneumoniae and that caused by Escherichia coli.Kaplan-Meier method was employed to establish the survival curve of technical failure,and multivariate Logistic regression to analyze the risk factors of the treatment failure of PADP caused by Klebsiella pneumoniae. Results In the 4 peritoneal dialysis centers,1034 cases of PDAP occurred in 586 patients from 2014 to 2019,including 21 cases caused by Klebsiella pneumoniae and 98 cases caused by Escherichia coli.The incidence of Klebsiella pneumoniae caused PDAP was 0.0048 times per patient per year on average,ranging from 0.0024 to 0.0124 times per patient per year during 2014-2019.According to the Kaplan-Meier survival curve,the technical failure rate of Klebsiella pneumoniae caused PDAP was higher than that of Escherichia coli caused PDAP (P=0.022).The multivariate Logistic regression model showed that long-term dialysis was an independent risk factor for the treatment failure of Klebsiella pneumoniae caused PDAP (OR=1.082,95%CI=1.011-1.158,P=0.023).Klebsiella pneumoniae was highly sensitive to amikacin,meropenem,imipenem,piperacillin,and cefotetan,and it was highly resistant to ampicillin (81.82%),cefazolin (53.33%),tetracycline (50.00%),cefotaxime (43.75%),and chloramphenicol (42.86%). Conclusion The PDAP caused by Klebsiella pneumoniae had worse prognosis than that caused by Escherichia coli,and long-term dialysis was an independent risk factor for the treatment failure of Klebsiella pneumoniae caused PDAP.

Melanoma metastásico en intestino delgado: causa infrecuente de perforación: reporte de caso / Metastatic melanoma in the small intestine: infrequent cause of perforation: case report / Melanoma metastático em intestino delgado: causa rara de perfuração: relato de caso

El intestino delgado es el sitio de asiento más frecuente del melanoma metastásico. Su diagnóstico es un desafío por cursar asintomático o con síntomas inespecíficos. Son pocos los casos que presentan complicaciones, siendo infrecuente la peritonitis por perforación. El objetivo del trabajo es comunicar el caso clínico de una peritonitis por perforación de una metástasis de melanoma en intestino delgado. Caso clínico: Paciente de sexo masculino de 66 años con diagnóstico de melanoma de cuello y secundario óseo, encefálico y pulmonar, fue intervenido de urgencia por peritonitis aguda por perforación de metástasis en intestino delgado. El estudio histológico confirmó secundarismo de melanoma cutáneo. Conclusión: Sabiendo que el yeyuno íleon es el sitio de asiento más frecuente de las metástasis de melanoma, ante la presencia de síntomas digestivos inespecíficos o anemia se debe sospechar su compromiso y evaluar posibles alternativas terapéuticas.

The small intestine is the most frequent site of metastatic melanoma. However, its diagnosis continues to be a challenge since it is usually asymptomatic or with non-specific symptoms. Few cases result in complications, peritonitis due to perforation being infrequent. The objective of the work is to report a clinical case of peritonitis due to perforation of a melanoma metastasis in the small intestine. Clinical case: A 66-year-old male patient diagnosed with melanoma of the neck and secondary bone, brain and lung melanoma, underwent emergency surgery for acute peritonitis due to perforation of metastasis in the small intestine, which was resected and anastomosed. The histology confirmed the secondary nature of the cutaneous melanoma. Conclusion: Knowing that the jejunum-ileum is the most frequent site of melanoma metastases, in the presence of non-specific digestive symptoms or anemia, its involvement should be suspected and possible therapeutic alternatives should be evaluated.

O intestino delgado é o local mais frequente de melanoma metastático. O diagnóstico é um desafio por ser assintomático ou apresentar sintomas inespecíficos.

Biliary peritonitis was of traumatic origin in two patients, and typhoid in eight. Postoperatively, there were four cases of sepsis and three cases of parietal suppuration. Three patients died. Conclusion: Biliary peritonitis discovered during laparotomies for peritonitis, was secondary to typhoid cholecystitis, and had a high morbidity and mortality.

Diagnóstico, manejo y tratamiento de pacientes con peritonitis secundaria en una unidad de cirugía general / Diagnosis, management and treatment of patients with secondary peritonitis in a general surgery unit

La peritonitis es una inflamación aguda o crónica del peritoneo que generalmente tiene un origen infeccioso. Existen varios tipos, siendo la de tipo secundario la más frecuente. El término peritonitis secundaria se define como la inflamación localizada o generalizada de la membrana peritoneal causada por infección polimicrobiana posterior a la ruptura traumática o espontánea de una víscera o secundaria a la dehiscencia de anastomosis intestinales. Esta entidad se caracteriza por la presencia de pus en la cavidad peritoneal o de líquido; que, en el estudio microscópico directo, contiene leucocitos y bacterias. El tratamiento de esta patología constituye una urgencia y puede ser de tipo clínico y/o quirúrgico. El objetivo del manejo operatorio se basa en identificar y eliminar la causa de la infección, recoger muestras microbiológicas, realizar una limpieza peritoneal y prevenir la recidiva. El tratamiento clínico se ocupa de las consecuencias de la infección mediante la reanimación perioperatoria y el tratamiento antibiótico1. A pesar de los avances en diagnóstico, procedimientos quirúrgicos, terapia antimicrobiana y cuidados intensivos, la mortalidad asociada con la peritonitis secundaria grave es aún muy alta. El pronóstico y el manejo oportuno representan la clave para mejorar la sobrevida y reducir la mortalidad asociada a infecciones intraabdominales extensas2. Es importante establecer lineamientos en cuanto al diagnóstico, manejo antibiótico y pautas de tratamiento quirúrgico para disminuir la morbilidad y mortalidad asociada a esta enfermedad. Palabras clave: Peritonitis; Peritoneo; Cavidad Abdominal/cirugía; Cavidad Peritoneal; Líquido Ascítico/patología; Procedimientos Quirúrgicos Operativos.

Peritonitis is an acute or chronic inflammation of the peritoneum that generally has an infectious origin. There are several types, with secondary peritonitis being the most frequent. The term secondary peritonitis is defined as localized or generalized inflammation of the peritoneal membrane caused by polymicrobial infection following traumatic or spontaneous rupture of a viscus or secondary to dehiscence of intestinal anastomoses. This entity is characterized by the presence of pus in the peritoneal cavity or fluid which, on direct microscopic examination, contains leukocytes and bacteria. The treatment of this pathology constitutes an emergency and can be clinical and/or surgical. The aim of operative management is based on identifying and eliminating the cause of the infection, collecting microbiological samples, performing peritoneal cleansing and preventing recurrence. Clinical management deals with the consequences of the infection by perioperative resuscitation and antibiotic treatment1 . Despite advances in diagnosis, surgical procedures, antimicrobial therapy and intensive care, mortality associated with severe secondary peritonitis is still very high. Prognosis and timely management represent the key to improving survival and reducing mortality associated with extensive intra-abdominal infections2. It is important to establish guidelines for diagnosis, antibiotic management and surgical treatment guidelines to reduce the morbidity and mortality associated with this disease.

Eficacia de la impronta citológica peritoneal para decidir cuándo detener los lavados peritoneales programados / Efficacy of Peritoneal Cytological Imprinting in Deciding When to Stop Scheduled Peritoneal Lavages

Introducción: La no existencia de un parámetro preestablecido que permita determinar el momento preciso para suspender los lavados peritoneales programados, conlleva a que muchas veces se realice un número insuficiente de ellos, o tal vez estos se prolonguen de forma innecesaria y aumentan las probabilidades de fallecimiento del paciente. Objetivo: Determinar la eficacia de la impronta citológica peritoneal para decidir cuándo detener los lavados peritoneales programados. Métodos: Se realizó un estudio descriptivo de exactitud diagnóstica, en una serie de casos, con recogida prospectiva de datos desde enero de 2010 hasta diciembre de 2014, en el Hospital Provincial Clínico-Quirúrgico Docente "Celia Sánchez Manduley. La muestra quedó conformada por 42 pacientes que fueron tratados por peritonitis secundaria persistente. Se clasificaron según cuatro categorías de correlación y se tomó como estándar de referencia a la biopsia por parafina. Resultados: Las muestras con inflamación aguda peritoneal y curación de la inflamación peritoneal se identificaron correctamente en 39/42 casos, por lo tanto, el porcentaje predictivo global de la impronta citológica fue del 92,86 por ciento. La sensibilidad en el diagnóstico de inflamación aguda peritoneal fue del 100 por ciento, la especificidad del 92,68 por ciento, el valor predictivo positivo fue del 24,99 por ciento y el valor predictivo negativo del 100 por ciento. Las razones de verosimilitudes positiva y negativa fueron 13,67 y 0, respectivamente. El coeficiente (κ) fue de 0,376. Conclusiones: La impronta citológica peritoneal constituye un método diagnóstico eficaz para descartar inflamación aguda peritoneal cuando el resultado es negativo y se consideró de gran utilidad para detener los lavados peritoneales programados(AU)

Introduction: The lack of a pre-established parameter that allows determining the precise moment to suspend the scheduled peritoneal lavages, often leads to performing insufficient number of them, or perhaps these are unnecessarily prolonged, increasing the probability of the patient´s death. Objective: To determine the efficacy of peritoneal cytological imprinting in deciding when to stop scheduled peritoneal lavages. Methods: A descriptive study of diagnostic accuracy was carried out, in a series of cases, with prospective data collection in the five-year period from 2010 to 2014 at Celia Sánchez Manduley Provincial Clinical-Surgical Teaching Hospital. The sample was made up of 42 patients who were treated for persistent secondary peritonitis. They were classified according to four correlation categories, taking paraffin biopsy as reference standard. Results: Samples with acute peritoneal inflammation and healing of peritoneal inflammation were correctly identified in 39/42 cases. Therefore, the global predictive percentage of the cytological imprint was 92.86 percent. The sensitivity in the diagnosis of acute peritoneal inflammation was 100 percent, the specificity was 92.68 percent, the positive predictive value was 24.99 percent, and the negative predictive value was 100 percent. The positive and negative likelihood ratios were 13.67 and 0, respectively. Cohen's kappa coefficient (κ) was 0.376. Conclusions: The peritoneal cytological imprint is an effective diagnostic method to rule out acute peritoneal inflammation when the result is negative and it was considered very useful to stop scheduled peritoneal lavages(AU)

Caracterización clínica de la peritonitis secundaria en una institución de tercer nivel y factores relacionados con mortalidad / Clinical characterization of secondary peritonitis in a tertiary level of care institution and factors related to mortality

Introducción. La peritonitis secundaria es una enfermedad con altos índices de mortalidad, por lo que se considera de gran importancia identificar los factores que inciden en ella. Método. Se realizó un estudio analítico entre 2019 y 2020 en el que se incluyeron pacientes con peritonitis secundaria, se caracterizaron las variables más relacionadas con el pronóstico, como aspectos demográficos y clínicos, y se analizó la asociación entre la mortalidad y estas variables. Resultados. La mortalidad hospitalaria fue del 30,7 %, encontrando como condiciones relacionadas con la mortalidad la ubicación de la fuente séptica en abdomen superior, la presencia de dolor en abdomen superior, atención en UCI, control del foco en la primera intervención, pacientes que cursaron con falla renal, edad del paciente y valores de hemoglobina. Conclusiones. En la cohorte estudiada se encontraron índices de mortalidad dos veces superiores a los reportados en Suramérica y 1,5 veces a los del resto del país. El mayor poder predictivo de mortalidad en el análisis bivariado fue dado por la presencia de falla renal y el valor de la hemoglobina.

Introduction. Secondary peritonitis is a disease with high mortality rates, so it is considered of great importance to identify the factors that affect it. Methods. An analytical study was carried out between 2019 and 2020 in which patients with secondary peritonitis were included, the variables most related to prognosis were characterized, such as demographic and clinical aspects, and the association between mortality and these variables was analyzed. Results. Hospital mortality was 30.7%, finding conditions related to mortality to be the location of the septic source in the upper abdomen, the presence of pain in the upper abdomen, care in the ICU, control of the focus in the first intervention, patients who underwent kidney failure, patient age, and hemoglobin values. Conclusion. Mortality rates were found in the studied cohort twice higher than those reported in South America and 1.5 times higher than those of the rest of the country. The greatest predictive power of mortality in the bivariate analysis was given by the presence of kidney failure and hemoglobin.

RESUMEN La nutrición enteral es parte importante del soporte vital avanzado en el paciente crítico, y ha demostrado ser más fisiológica, económica y con resultados superiores a la nutrición parenteral. La yeyunostomía para alimentación enteral está indicada cuando no es posible la alimentación por vía oral y está contraindicada la utilización de una sonda nasogástrica o nasoyeyunal de alimentación. Es una vía de alimentación con escasa morbilidad, aunque no está exenta de complicaciones, y algunas de ellas pueden ser graves. Comunicamos un caso de necrosis intestinal vinculado a la alimentación enteral por yeyunostomía en un paciente sometido a una gastrectomía oncológica.

ABSTRACT Enteral nutrition is an important component of advanced life support in the critically ill patient, and has demonstrated to be more physiologic, cheaper and with better results than parenteral nutrition. Jejunostomy for enteral nutrition is indicated when the oral route is impossible and the use of a nasogastric or nasojejunal feeding tube is contraindicated. Although the rate of complications associated with enteral nutrition through jejunostomy is low, they may occur and be serious. We report a case of bowel necrosis associated with a jejunostomy performed for enteral nutrition in a patient who underwent oncologic gastrectomy.

Does ascitic fluid filtration improve the microbiological diagnosis of spontaneous bacterial peritonitis? An experimental laboratory study / A filtração do líquido ascítico melhora o diagnóstico microbiológico da peritonite bacteriana espontânea? Um estudo experimental laboratorial

Background: Spontaneous Bacterial Peritonitis (SBP) is a serious and frequent complication among cirrhotic patients with ascites and can be diagnosed by cytological analysis of the ascitic fluid. The microbiological culture of ascitic fluid, however, is positive in less than 40% of SBP cases, which often results in inappropriate antimicrobial therapy. Empirical therapy may be suboptimal, increasing patient's risk of aggravation, or overestimated, unnecessarily boosting bacterial resistance. Objective: This experimental laboratory study aimed to standardize and verify the technical feasibility of ascitic fluid vacuum filtration, as a way to optimize the etiological diagnosis of SBP, compared to the automated method. Method: The method evaluated and standardized in this study was ascitic fluid vacuum filtration. Its principle is the concentration of bacteria on a filter membrane. Results: This study included 36 cirrhotic patients treated at a public university hospital between 11.13.2017 and 06.30.2019. Among them, 47.2% (17/36) presented cytology test results compatible with SBP. For these patients, culture sensitivity using the automated method was 35.3% (6/17), against 11.8% (2/17) with the vacuum filtration method. Conclusion: In conclusion, vacuum filtration does not improve the microbiological diagnosis of SBP in this population compared to the automated method (AU)

Contexto: A Peritonite Bacteriana Espontânea (PBE) é uma complicação grave e frequente entre pacientes cirróticos com ascite, diagnosticada por meio da análise citológica do líquido ascítico. A cultura microbiológica do líquido ascítico, por sua vez, é positiva em menos de 40% dos casos de PBE, o que resulta frequentemente na instituição de terapia antimicrobiana inapropriada. A terapia empírica pode ser subótima, aumentando o risco de agravamento do paciente, ou superestimada, impulsionando desnecessariamente a resistência bacteriana. Objetivo: Estudo experimental laboratorial, propôs padronizar e verificar a viabilidade técnica da filtração a vácuo do líquido ascítico, como forma de otimizar o diagnóstico etiológico na PBE, comparativamente ao sistema automatizado de culturas de sangue. Método: O método avaliado e padronizado neste estudo foi a da filtragem a vácuo do líquido ascítico. Esse tem como princípio a concentração da bactéria em uma membrana filtrante. Resultados: Nesse estudo, foram incluídos 36 pacientes cirróticos atendidos em um hospital público universitário, entre 13.11.2017 e 30.06.2019. Entre eles, 47,2% (17/36) apresentaram citologia compatível com PBE. Nesses, a sensibilidade da cultura pelo método semi-automatizado foi de 35,3% (6/17) e da cultura pelo método da filtragem a vácuo foi de 11,8% (2/17). Conclusão: Em conclusão, a filtragem a vácuo não melhora o diagnóstico microbiológico da PBE em relação ao método automatizado (AU)

Intestinal Perforation and Perianal Ulcer Due to Parasitic Infection / Perforación intestinal y úlcera perianal por infección parasitaria

Abstract Balantidium coli is the largest protozoan and the only ciliated parasite that infects humans. It causes balantidiasis, a disease humans acquire by fecal-oral transmission from its usual host: the pig. We report the case of an immunocompetent schoolgirl who presented with peritonitis due to intestinal perforation, with perianal ulceration secondary to polyparasitism caused by Balantidium coli, Enterobius vermicularis, and Trichuris trichiura. It is a rare, potentially preventable complication with extremely high mortality rates. The patient required eight surgical interventions.

Resumen Balantidium coli es el protozoario más grande y el único parásito ciliado que infecta a los seres humanos. Es el causante de la balantidiasis, enfermedad adquirida por los humanos por transmisión fecal-oral desde su hospedero habitual: el cerdo. Reportamos el caso de una escolar inmunocompetente, que presentó peritonitis por perforación intestinal, con ulceración perianal secundaria a poliparasitismo por Balantidium coli, Enterobius vermicularis y Trichuris trichiura. Esta es una complicación poco frecuente, potencialmente prevenible y con tasas de mortalidad extremadamente altas. La paciente requirió 8 intervenciones quirúrgicas.

Development and validation of a prediction model for treatment failure in peritoneal dialysis-associated peritonitis patients: a multicenter study / 南方医科大学学报

OBJECTIVE@#To develop and validate a risk prediction model of treatment failure in patients with peritoneal dialysis-associated peritonitis (PDAP).@*METHODS@#We retrospectively analyzed the data of patients undergoing peritoneal dialysis (PD) in 3 dialysis centers in Jilin Province who developed PDAP between January 1, 2013 and December 31, 2019. The data collected from the Second Hospital of Jilin University and Second Division of First Hospital of Jilin University) were used as the training dataset and those from Jilin Central Hospital as the validation dataset. We developed a nomogram for predicting treatment failure using a logistic regression model with backward elimination. The performance of the nomogram was assessed by analyzing the C-statistic and the calibration plots. We also plotted decision curves to evaluate the clinical efficacy of the nomogram.@*RESULTS@#A total of 977 episodes of PDAP were included in the analysis (625 episodes in the training dataset and 352 episodes in the validation dataset). During follow-up, 78 treatment failures occurred in the training dataset and 35 in the validation dataset. A multivariable logistic regression prediction model was established, and the predictors in the final nomogram model included serum albumin, peritoneal dialysate white cell count on day 5, PD duration, and type of causative organisms. The nomogram showed a good performance in predicting treatment failure, with a C-statistic of 0.827 (95% CI: 0.784-0.871) in the training dataset and of 0.825 (95% CI: 0.743-0.908) in the validation dataset. The nomogram also performed well in calibration in both the training and validation datasets.@*CONCLUSION@#The established nomogram has a good accuracy in estimating the risk of treatment failure in PDAP patients.

The clinical value of von Willebrand factor and VITRO score in evaluating disease progression in patients with HBV infection / 中华肝脏病杂志

Objective: To explore the clinical value of von Willebrand Factor (vWF) and VITRO score (vWF:Ag/platelet count) in assessing disease progression in patients with HBV infection. Methods: Randomly collect relevant clinical data of 308 patients with HBV infection (including 154 cases of chronic hepatitis B, 66 cases of hepatitis B cirrhosis in compensatory period, 88 cases of hepatitis B cirrhosis in decompensated period) from December 1, 2018 to January 5, 2021 in the Second Affiliated Hospital of Chongqing Medical University. The vWF values are measured by a uniform optical method, and all data are included using a uniform standard. Analyze the difference and significance of plasma vWF level and VITRO score in chronic hepatitis B, hepatitis B cirrhosis in the compensatory phase and decompensated phase. Results: The plasma vWF level and VITRO score of the chronic hepatitis B group were (139.47±76.44) and (0.86±0.8), respectively, and the hepatitis B cirrhosis compensated group was (164.95±67.12 and 1.44±1.14), respectively. Hepatitis cirrhosis decompensated group were (317.48±103.32 and 6.81±4.98), respectively; plasma vWF level and VITRO score increased with the progression of HBV infection, and the difference was statistically significant (F=133.669,P=0.000F=137.598,P=0.000).The plasma vWF level and VITRO score in patients with hepatitis B cirrhosis were (185.65±85.07 and 2.3±2.37) in the Child-Pugh A group, (304.74±105.81 and 6.37±5.19) in the B grade group, and (369.48±73.238.28±5.38) in the C grade group; plasma vWF level and VITRO score in patients with hepatitis B cirrhosis increased with the increase of Child-Pugh grade, and the difference was statistically significant (F=60.236, P=0.000F=32.854, P=0.000). The area under the curve (AUC) of plasma vWF level and VITRO score for diagnosing the decompensated stage of hepatitis B cirrhosis were 0.897 [95% confidence interval (CI): 0.855-0.940, P＜0.01], 0.949 [95% CI: 0.916-0.982, P＜0.01). When the vWF level and VITRO score were taken as cut-off values of 238.5% and 1.65, respectively, the sensitivity of diagnosing the decompensated stage of hepatitis B cirrhosis was 79.5% and 94.3%, the specificity was 92.3% and 87.7%, and the positive predictive value was 80.5% and 94.3%, the negative predictive value was 91.9% and 97.5%, and the diagnostic accuracy was 88.6% and 89.3%. Among the patients with decompensated hepatitis B cirrhosis, the level of vWF in the group with gastrointestinal bleeding (367.24±68.29)% was significantly higher than that in the group without gastrointestinal bleeding (286.15±109.69)%, and the difference was statistically significant (P＜0.001) The VITRO score of the group with gastrointestinal bleeding (9.12±5.4) was significantly higher than that of the group without gastrointestinal bleeding (5.36±4.13), and the difference was statistically significant (P＜0.01). The vWF level in the spontaneous peritonitis group was (341.73±87.92)% higher than that in the non-spontaneous peritonitis group (296.32±111.74)%, and the difference was statistically significant (P＜0.05). There was no statistical difference in VITRO score between the two groups. significance. Conclusion: Plasma vWF level and VITRO score can evaluate the progression of liver disease and the degree of decompensation of liver cirrhosis in patients with HBV infection, and have a predictive effect on various complications after decompensation of liver cirrhosis, and have certain guiding significance for early intervention measures.

Clinical Characteristics and Treatment Outcome of Pseudomonas Peritoneal Dialysis-associated Peritonitis / 中国医学科学院学报

Objective To explore the clinical characteristics and treatment of Pseudomonas peritoneal dialysis-associated peritonitis(PsP). Methods The data of patients receiving peritoneal dialysis in four tertiary hospitals in Jilin province from 2015 to 2019 were retrospectively analyzed.According to the etiological classification,the patients with peritoneal dialysis-associated peritonitis(PDAP)were classified into PsP group and non-PsP group.The incidence of PsP was calculated,and the clinical characteristics and treatment outcomes of the two groups were compared.Kaplan-Meier method was used to draw the survival curve,and Cox regression was performed to analyze the risk factors affecting the technical failure of PsP.The treatment options of Pseudomonas aeruginosa-caused PDAP and the drug sensitivity of PsP were summarized. Results A total of 1530 peritoneal dialysis patients with complete data were included in this study,among which 439 patients had 664 times of PDAP.The incidence of PsP was 0.007 episodes/patient-year.PsP group had higher proportion of refractory peritonitis(41.38% vs.19.69%,P=0.005),lower cure rate(55.17% vs.80.79%, P=0.001),and higher extubation rate(24.14% vs.7.09%,P=0.003)than non-PsP group.The technical survival rate of PsP group was lower than that of non-PsP group(P<0.001).Multivariate Cox regression analysis showed that Pseudomonas aeruginosa was an independent risk factor for technical failure in patients with PsP(HR=9.020,95%CI=1.141-71.279,P=0.037).Pseudomonas was highly sensitive to amikacin,meropenem,and piperacillin-tazobactam while highly resistant to compound sulfamethoxazole,cefazolin,and ampicillin. Conclusion The treatment outcome of PsP is worse than that of non-PsP,and Pseudomonas aeruginosa is an independent risk factor for technical failure of PsP.
