ABSTRACT

La tuberculosis es una enfermedad infectocontagiosa cuya forma de presentación más frecuente es la pulmonar; la afectación abdominal es poco frecuente, por lo que su diagnóstico continúa siendo un desafío. Las manifestaciones clínicas de la tuberculosis abdominal así como sus hallazgos en el examen físico suelen ser inespecíficos y, en muchas ocasiones, similares a los de otras patologías, por lo que es fundamental considerarla entre los diagnósticos diferenciales. Se presenta el caso clínico de un paciente de sexo masculino, de 15 años de edad, hospitalizado por un síndrome febril prolongado asociado a dolor abdominal, diarrea, sudoración nocturna y pérdida de peso


Tuberculosis is an infectious disease which most commonly compromises the respiratory system, whereas abdominal involvement is rare, thus its diagnosis is a challenge. The clinical manifestations of abdominal tuberculosis as well as its physical examination findings are usually non-specific and, frequently, similar to those of other diseases, so it is critical to consider abdominal tuberculosis among the differential diagnoses. Here we report the clinical case of a 15-year-old male patient hospitalized for a prolonged febrile syndrome associated with abdominal pain, diarrhea, night sweats, and weight loss.

ABSTRACT

Introduction: McKittrick-Wheelock syndrome is a rare entity characterized by chronic diarrhea, acute kidney injury, and hydroelectrolytic imbalance associated with a large rectal tumor, frequently a villous adenoma. Case report: A 69-year-old male with chronic diarrhea with mucus. He underwent a colonoscopy with biopsies, reporting adenocarcinoma of the rectum in situ, and underwent a robot assisted intersphincteric resection with colo-anal anastomosis and a protecitive ileostomy. Discussion: Described in 1954, this syndrome is manifested by electrolyte imbalance and acute renal injury secondary to diarrhea associated with a rectal villous adenoma, often with long lasting symptoms. The most frequent symptom being watery diarrhea with mucus. The definitive treatment consists of surgical resection. Conclusion: Although this is a rare pathology, it should be considered as a differential diagnosis in cases of chronic diarrhea associated with water and electrolyte disorders. (AU)

ABSTRACT

Introducción. El síndrome post-colecistectomía fue descrito hace más de 70 años y se define como la presencia de síntomas gastrointestinales que pueden persistir después de la colecistectomía o aparecer como nuevos síntomas. Este síndrome, poco conocido, puede manifestarse desde pocos meses hasta varios años luego de la cirugía y ocurre entre 5 % y 40 % de los pacientes. Método. Estudio de cohorte prospectiva, que incluyó pacientes a quienes se les realizó colecistectomía laparoscópica en tres unidades quirúrgicas de Bogotá, D.C., Colombia, durante un período de ocho meses, con seguimientos periódicos durante dos años. El síndrome post-colecistectomía se definió como la presencia de al menos un síntoma gastrointestinal a partir del primer mes de la cirugía. Resultados. Se incluyeron 380 pacientes de los cuales 183 (48,2 %) desarrollaron el síndrome. La edad tuvo diferencia estadísticamente significativa entre aquellos que lo desarrollaron y los que no (p=0,024). La diarrea fue el único síntoma preoperatorio asociado al desarrollo del síndrome. El síndrome post-colecistectomía se encontró en el 42,1 % de los pacientes al primer mes de seguimiento y en el 17,4 % al segundo año. Conclusiones. El síndrome post-colecistectomía ocurre en un porcentaje importante de pacientes. En concordancia con la literatura, se encontró que la diarrea prequirúrgica es un factor de riesgo independiente para el desarrollo del síndrome. Se recomienda un adecuado seguimiento de los pacientes después de una colecistectomía


Introduction. Post-cholecystectomy syndrome (PCS) was described more than 70 years ago and is defined as the presence of gastrointestinal (GI) symptoms that may persist after cholecystectomy or can present as new symptoms. This little-known syndrome can appear from a few months to several years after surgery and occurs between 5% and 40% of patients. Method. Prospective cohort study, which included patients who underwent laparoscopic cholecystectomy in three surgical units in Bogotá, Colombia, during a period of eight months, with periodic follow-up for two years. PCS was defined as the presence of at least one GI symptom from the first month after surgery. Results. Three-hundred and eighty patients were included, of which 183 (48.2%) developed the syndrome. Age had a statistically significant difference between those who developed PCS and those who did not (p=0.024). Diarrhea was the only preoperative symptom associated with the development of PCS. Post-cholecystectomy syndrome was found in 42.1% at the first month of follow-up and in 17.4% at the second year. Conclusions. Post-cholecystectomy syndrome occurs in a significant percentage of patients. Consistent with the literature, preoperative diarrhea was found to be an independent risk factor for the development of the syndrome. Adequate follow-up of patients after cholecystectomy is recommended

ABSTRACT

El síndrome urémico hemolítico (SUH), descripto en 1955, se caracteriza por la tríada de anemia hemolítica no inmunomediada, trombocitopenia y lesión renal aguda. En su patogenia interviene la toxina Shiga, producida con mayor frecuencia por E. coli O157:H. Puede manifestarse a cualquier edad, aunque es infrecuente en adultos, y se desarrolla en forma esporádica o en brote. Se presenta con un cuadro de dolor abdominal, diarrea, fiebre y vómitos. Puede afectar el sistema nervioso central, pulmones, páncreas y corazón. En adultos, el síndrome evoluciona tras un período de incubación de 1 semana posterior a la diarrea y tiene alta morbimortalidad, a diferencia de los casos pediátricos. Presentamos el caso de una paciente adulta, que cursó internación por síndrome urémico hemolítico. (AU)


Hemolytic uremic syndrome (HUS), described in 1955, is characterized by the triad of non-immune mediated hemolytic anemia, thrombocytopenia, and acute kidney injury. Shiga toxin, produced most frequently by E coli O157:H, is involved in its pathogenesis. Hus can manifest at any age, although it is rare in adults and develops sporadically or in outbreaks. HUS presents with a picture of abdominal pain, diarrhea, fever and vomiting. It can affect the central nervous system, lungs, pancreas, and heart.In adults, the syndrome evolves after an incubation period of 1 week after diarrhea, with high morbidity and mortality, unlike pediatric cases.We present the case of an adult patient who was hospitalized for hemolytic uremic syndrome.

ABSTRACT

El síndrome de enterocolitis inducido por proteínas de los alimentos (FPIES, por su sigla en inglés) es una reacción alérgica no mediada por inmunoglobulina E (IgE) con síntomas gastrointestinales, como vómitos y diarrea. El diagnóstico se basa en criterios clínicos y en una prueba de provocación para confirmarlo. Es una enfermedad desconocida en las unidades neonatales, debido a la inespecificidad de los síntomas en los recién nacidos. La cifra de metahemoglobina elevada es una opción sencilla de aproximación diagnóstica. Se describe el caso clínico de un recién nacido que ingresa al servicio de urgencias por deshidratación, letargia, vómitos, diarrea y acidosis metabólica grave con elevación de metahemoglobina, con mejora clínica y recuperación total tras el inicio del aporte de fórmula elemental. La sospecha diagnóstica se confirmó tras la prueba de provocación positiva.


Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE mediated allergic reaction with gastrointestinal symptoms, such as vomiting and diarrhea. FPIES diagnosis is based on clinical criteria and on a food challenge test. It is an unknown disease in neonatal units due to its nonspecific symptoms in newborn infants. An elevated methemoglobin level is a simple way to approach diagnosis. Here we describe a clinical case of a newborn admitted to the emergency department because of dehydration, lethargy, vomiting, diarrhea, severe metabolic acidosis, and a high methemoglobin level. Clinical improvement and complete recovery was achieved after initiation of elemental formula. The diagnostic suspicion was confirmed after a positive challenge test.

ABSTRACT

Las diarreas y enteropatías congénitas (CODE por su sigla en inglés) son un grupo de trastornos monogénicos que se han descrito en los últimos años. Dentro de las CODE, la mutación del gen de la diacilglicerol o-aciltransferasa 1 (DGAT1) es un trastorno enzimático poco común asociado con diarrea crónica grave de aparición temprana. El objetivo es presentar a dos hermanas que consultaron por diarrea crónica, retraso en el crecimiento, vómitos e hipoalbuminemia en la primera infancia. En ambas pacientes se encontró un compuesto heterocigota de la mutación del DGAT1. Esta mutación se describió previamente en la población asiática; sin embargo, estas son las dos primeras pacientes en tener esta mutación en la población latinoamericana. Estos dos casos pueden ampliar nuestro conocimiento sobre las diarreas congénitas en general y las características clínicas de los pacientes con mutaciones en DGAT1 en particular.


Congenital diarrhea and enteropathies (CODEs) are a group of monogenic disorders that have been described in recent years. Within the CODEs, the mutation in the diacylglycerol O-acyltransferase 1 (DGAT1) gene is a rare enzyme disorder associated with severe, early-onset chronic diarrhea. Our objective is to describe the case of 2 sisters who consulted for chronic diarrhea, growth retardation, vomiting, and hypoalbuminemia in early childhood. A compound heterozygous DGAT1 mutation was found in both patients. This mutation was previously described in the Asian population; however, these are the first 2 patients to show this mutation in the Latin American population. These 2 cases may expand our knowledge about congenital diarrhea in general and the clinical characteristics of patients with DGAT1 mutations in particular.

ABSTRACT

Introdução: A suplementação nutricional em pessoas vivendo com HIV ainda é pouco difundida, sendo essencial o levantamento de evidências que apontem as terapêuticas mais eficientes para beneficiar a saúde desta população. Ao se tratar do público infantil, no qual a prevalência de carências nutricionais é elevada, o conhecimento acerca da suplementação nutricional é bastante profícuo. Objetivo: Analisar relatórios de pesquisa acerca dos efeitos do uso de suplementos nutricionais em crianças vivendo com HIV. Desenho do estudo e local: Uma revisão narrativa realizada na Universidade Federal do Maranhão, em Imperatriz, município localizado no oeste do estado do Maranhão. Método: Foi realizada uma busca nos bancos de dados Cochrane, PubMed, Scopus, WHO/OMS e biblioteca digital de teses e dissertações da USP entre setembro de 2021 a janeiro de 2022. Resultados: Foram incluídas 26 produções, as quais demonstraram que o uso de múltiplos nutrientes reduziu o tempo de hospitalização em crianças admitidas com diarreia ou pneumonia, melhorando a morbidade, concentração de hemoglobina e ganho ponderal. A oferta de ferro foi considerada satisfatória no combate à progressão da doença, vitamina A melhorou o quadro de diarreia persistente e vitamina D a habilidade motora neuromuscular. Conclusão: Os estudos sobre suplementação nutricional e a relação dos nutrientes com os diversos aspectos de saúde das crianças vivendo com HIV tem avançado. Logo, é necessário alargar as pesquisas no tema em contextos distintos, a fim de incrementar e gerar novas evidências, colaborando para uma conduta mais assertiva dos profissionais de saúde e consequente melhora no prognóstico dessas crianças.


Background: Providing nutritional supplementation to people living with human immunodeficiency virus (HIV) is a therapeutic intervention still not widespread, so it is essential to gather evidence supporting efficient therapies to benefit the health of this population. The prevalence of nutritional deficiencies is high in children; consequently, the knowledge about nutritional supplementation in this age group is quite fruitful. Objective: To analyze research reports on the effects of nutritional supplementation in children living with HIV. Design and setting: A narrative review was conducted at the Federal University of Maranhão, Imperatriz, west of the Maranhão State. Methods: The searches were performed in the Cochrane, PubMed, Scopus, and World Health Organization (WHO) databases and the São Paulo University's digital library of theses and dissertations from September 2021 to January 2022. Results: Twenty-six studies were included and showed that using multiple nutrients reduced the hospitalization time of children admitted with diarrhea or pneumonia, improving morbidity, hemoglobin concentration, and weight gain. The supply of iron was considered effective in combating the progression of the disease, vitamin A improved the condition of persistent diarrhea, and vitamin D improved neuromuscular motor skills. Conclusion: Studies have advanced on nutritional supplementation, the relationship between nutrients, and the different health aspects of children living with HIV. Therefore, it is necessary to expand research on the subject in different contexts to increase and generate new evidence, contributing to more assertive conduct of health professionals and consequent improvement in the prognosis of these children.


Antecedentes: La administración de suplementos nutricionales a las personas que viven con el virus de la inmunodeficiencia humana (VIH) es una intervención terapéutica aún poco extendida, por lo que es fundamental reunir pruebas que apoyen terapias eficaces en beneficio de la salud de esta población. La prevalencia de deficiencias nutricionales es elevada en niños, por lo que el conocimiento sobre la suplementación nutricional en este grupo de edad es bastante fructífero. Objetivo: Analizar los informes de investigación sobre los efectos de la suplementación nutricional en niños que viven con el VIH. Diseño y escenario: Se realizó una revisión narrativa en la Universidad Federal de Maranhão, Imperatriz, al oeste del Estado de Maranhão. Métodos: Las búsquedas se realizaron en las bases de datos Cochrane, PubMed, Scopus y Organización Mundial de la Salud (OMS) y en la biblioteca digital de tesis y disertaciones de la Universidad de São Paulo desde septiembre de 2021 hasta enero de 2022. Resultados: Se incluyeron 26 estudios que mostraron que el uso de múltiples nutrientes redujo el tiempo de hospitalización de los niños ingresados con diarrea o neumonía, mejorando la morbilidad, la concentración de hemoglobina y el aumento de peso. El aporte de hierro se consideró eficaz para combatir la progresión de la enfermedad, la vitamina A mejoró el cuadro de diarrea persistente y la vitamina D mejoró las habilidades motoras neuromusculares. Conclusiones: Los estudios han avanzado sobre la suplementación nutricional, la relación entre los nutrientes y los diferentes aspectos de la salud de los niños que viven con el VIH. Por lo tanto, es necesario ampliar las investigaciones sobre el tema en diferentes contextos para aumentar y generar nuevas evidencias, contribuyendo para una conducta más asertiva de los profesionales de salud y consecuente mejoría en el pronóstico de estos niños.

ABSTRACT

Introducción: el síndrome hemolítico urémico (SHU) es en muchos países, de las causas más frecuentes de insuficiencia renal aguda. La mayoría de los casos ocurre luego de un episodio de gastroenteritis aguda (GEA) por Escherichia coli productora de toxina Shiga (STEC). En Uruguay a pesar de ser una enfermedad de notificación obligatoria, existe subregistro. Objetivo: describir dos casos clínicos de SHU asociados a GEA con nexo epidemiológico. Casos clínicos: se trata de dos varones de 4 y 5 años, sanos. En los días previos, ingesta de carne en el mismo local comercial. Consultaron por dolor abdominal, deposiciones líquidas y vómitos reiterados. El niño de 4 años presentaba fiebre y deposiciones líquidas con sangre. El niño de 5 años dolor abdominal. El estado de hidratación y las constantes vitales eran normales en ambos. Fueron admitidos a cuidados moderados. A las 48 horas y a los 5 días, respectivamente, agregan palidez cutáneo-mucosa intensa, edemas y oliguria. Estudios complementarios: anemia, plaquetopenia e insuficiencia renal. Ingresaron a cuidados intensivos y se realizó diálisis peritoneal. La investigación de STEC fue negativa y la evolución favorable. Conclusiones: en menores de 5 años el SHU asociado a GEA es la forma de enfermedad más frecuente. En Uruguay predominan las cepas STEC no-O157. En estos casos no se pudo identificar el agente. La existencia de un nexo epidemiológico alerta sobre la necesidad de extremar los cuidados en la preparación y cocción de la carne. Debido a la asociación con una enfermedad prevalente, es necesario tener presente esta complicación para poder sospecharla e iniciar el tratamiento en forma precoz y oportuna.


Introduction: hemolytic uremic syndrome (HUS) is one of the most frequent causes of acute renal failure in many countries. Most cases occur after an episode of acute gastroenteritis (GEA) due to the Shiga toxin producing Escherichia Soli (STEC). In Uruguay, despite being a disease that requires mandatory notification, it is under reported. Objective: to describe two clinical cases of HUS associated with GEA with an epidemiological link. Clinical cases: these are two healthy boys aged 4 and 5 years. In the previous days, they reported meat intake in the same commercial premises. They consulted for abdominal pain, liquid stools and repeated vomiting. The 4 year old boy had a fever and bloody stools. The 5 year old boy had abdominal pain. They both showed normal hydration levels and vital signs. They were admitted to moderate care. At 48 hours and 5 days, respectively, they showed intense skin and mucosal paleness, edema and oliguria. Complementary studies: anemia, thrombocytopenia and renal failure. They were admitted to intensive care and peritoneal dialysis was performed. The STEC's investigation was negative and the evolution favorable. Conclusions: in children under 5 years of age, HUS associated with GEA is the most frequent form of the disease. In Uruguay, non-O157 STEC strains predominate. In these cases, the agent could not be identified. The existence of an epidemiological link warns us about the need for extreme care in the preparation and cooking of meat. Due to the association with a prevalent disease, it is necessary to keep this complication in mind in order to suspect it and initiate early and timely treatment.


Introdução: a síndrome hemolítico urêmica (SHU) é uma das causas mais frequentes de insuficiência renal aguda em muitos países. A maioria dos casos ocorre após um episódio de gastroenterite aguda (GEA) devido à Escherichia Coli, a toxina produtora de Shiga (STEC). No Uruguai, apesar de ser uma doença de notificação compulsória, há subnotificação. Objetivo: descrever dois casos clínicos de SHU associada à AGE com vínculo epidemiológico. Casos clínicos: dois meninos saudáveis com idades entre 4 e 5 anos. Nos dias anteriores, eles reportaram consumo de carne nos mesmos estabe- lecimentos comerciais. Eles consultaram para dor abdominal, fezes líquidas e vômitos repetidos. O menino de 4 anos teve febre e fezes com sangue. O menino de 5 anos teve dores abdominais. O estado de hidratação e os sinais vitais foram normais em ambos meninos. Foram internados em cuidados moderados. Às 48 horas e 5 dias, respectivamente, apresentaram aliás palidez intensa da pele e mucosas, edema e oligúria. Realizaramse estudos complementares: anemia, trombocitopenia e insuficiência renal. Eles foram internados em terapia intensiva e realizouse diálise peritoneal. A investigação do STEC foi negativa e a evolução favorável. Conclusões: em crianças menores de 5 anos, a SHU associada à GEA é a forma mais frequente da doença. No Uruguai, predominam cepas STEC não-O157. Nesses casos, o agente não pôde ser identificado. A existência de um nexo epidemiológico alerta para a necessidade de extremo cuidado no preparo e cozimento da carne. Devido à associação com doença prevalente, é necessário considerar essa complicação para suspeitar e iniciar o tratamento precoce e oportunamente.

ABSTRACT

The intestine has a very important role in the homeostasis of the internal medium. Bile acids play a regulatory role in the digestion and absorption of nutrients. Among them, deoxycholic acid, when its luminal concentration increases due to bacterial overgrowth, modifies hydroelectrolytic transport, producing an increase in the volume of water and electrolytes in stools.


El intestino tiene un papel muy importante en la homeostasis del medio interno. Los ácidos biliares cumplen una función reguladora en la digestión y absorción de nutrientes. Entre ellos el ácido deoxicólico, cuando aumenta su concentración luminal por sobrecrecimiento bacteriano, modifica el transporte hidroelectrolítico produciendo aumento del volumen de agua y electrolitos en las deposiciones.

ABSTRACT

Chronic diarrhea is a frequent cause of consultation in daily clinical practice. There are multiple diagnostic algorithms that allow a staggered approach to the most frequent pathologies, leaving out some lesser-known ones. This article reports the case of a 66-year-old female patient with a history of arterial hypertension, dyslipidemia and resected AB thymoma and a history of chronic diarrhea of 8 weeks of evolution. The etiological study ruled out infectious causes, celiac disease and negative viral serology. Due to a history of thymoma, immunoglobulin count was performed, showing severe pan-hypogammaglobulinemia. Good's Syndrome is the combination of thymoma and hypogammaglobulinemia, where patients may present with diarrhea secondary to immunodeficiency. Hypogammaglobulinemia associated with the presence of a thymoma is a rare cause but widely described in the literature as Good's Syndrome. Therefore, it seems relevant to describe a case, its approach and subsequent management.


La diarrea crónica constituye una causa frecuente de consulta en la práctica clínica diaria. Existen múltiples algoritmos diagnósticos que permiten realizar un abordaje escalonado de las patologías más frecuentes y permiten descartar algunas menos conocidas. En el presente artículo se reporta el caso de una paciente de género femenino de 66 años, antecedentes de hipertensión arterial, dislipidemia y timoma AB resecado con historia de diarrea crónica de 8 semanas de evolución. Dentro del estudio etiológico se descartan las causas infecciosas, enfermedad celíaca y serologías virales negativas. Por antecedente de timoma, se realizó recuento de inmunoglobulinas, evidenciando una severa pan-hipogammaglobulinemia. El Síndrome de Good es la combinación de timoma e hipogammaglobulinemia, donde los pacientes podrían presentar diarreas secundarias a inmunodeficiencia. La hipogammaglobulinemia asociada a la presencia de un timoma es una causa poco frecuente pero ampliamente descrita en la literatura como Síndrome de Good. Por lo antes señalado, nos parece relevante describir un caso, su abordaje y manejo posterior.

ABSTRACT

Porcine epidemic diarrhea (PED) is a highly contagious disease that causes high mortality in suckling piglets. Although several licensed inactivated and live attenuated vaccines were widely used, the infection rate remains high due to unsatisfactory protective efficacy. In this study, mRNA vaccine candidates against PED were prepared, and their immunogenicity was evaluated in mice and pregnant sows. The mRNA PED vaccine based on heterodimer of viral receptor binding region (RBD) showed good immunogenicity. It elicited robust humoral and cellular immune responses in mice, and the neutralizing antibody titer reached 1:300 after a single vaccination. Furthermore, it induced neutralizing antibody level similar to that of the inactivated vaccine in pregnant sows. This study developed a new design of PED vaccine based on the mRNA-RBD strategy and demonstrated the potential for clinical application.

ABSTRACT

Bacillus cereus is a common foodborne pathogen. Accidently eating food contaminated by B. cereus will cause vomiting or diarrhea, and even death in severe cases. In the present study, a B. cereus strain was isolated from spoiled rice by streak culture. The pathogenicity and drug resistance of the isolated strain were analyzed by drug sensitivity test and PCR amplification of virulence-associated gene respectively. Cultures of the purified strain were injected intraperitoneally into mice to examine their effects on intestinal immunity-associated factors and gut microbial communities, to provide references for the pathogenic mechanism and medication guidance of these spoilage microorganisms. The results showed that the isolated B. cereus strain was sensitive to norfloxacin, nitrofurantoin, tetracycline, minocycline, ciprofloxacin, spectinomycin, clindamycin, erythrocin, clarithromycin, chloramphenicol, levofloxacin, and vancomycin, but resistant to bactrim, oxacillin and penicillin G. The strain carries seven virulence-associated genes including hblA, hblC, hblD, nheA, nheB, nheC and entFM, which are involved in diarrhea-causing toxins production. After infecting mice, the isolated B. cereus strain was found to cause diarrhea in mice, and the expression levels of immunoglobulins and inflammatory factors in the intestinal mucosae of the challenged mice were significantly up-regulated. Gut microbiome analysis showed that the composition of gut microbial community in mice changed after infection with B. cereus. The abundance of the uncultured_bacterium_f_Muribaculaceae in Bacteroidetes, which is a marker of body health, was significantly decreased. On the other hand, the abundance of uncultured_bacterium_f_Enterobacteriaceae, which is an opportunistic pathogen in Proteobacteria and a marker of dysbacteriosis, was significantly increased and was significantly positively correlated with the concentrations of IgM and IgG. These results showed that the pathogenic B. cereus carrying diarrhea type virulence-associated gene can activate the immune system by altering the composition of gut microbiota upon infection.

ABSTRACT

OBJECTIVE@#To explore the genotyping characteristics of human fecal Escherichia coli( E. coli) and the relationships between antibiotic resistance genes (ARGs) and multidrug resistance (MDR) of E. coli in Miyun District, Beijing, an area with high incidence of infectious diarrheal cases but no related data.@*METHODS@#Over a period of 3 years, 94 E. coli strains were isolated from fecal samples collected from Miyun District Hospital, a surveillance hospital of the National Pathogen Identification Network. The antibiotic susceptibility of the isolates was determined by the broth microdilution method. ARGs, multilocus sequence typing (MLST), and polymorphism trees were analyzed using whole-genome sequencing data (WGS).@*RESULTS@#This study revealed that 68.09% of the isolates had MDR, prevalent and distributed in different clades, with a relatively high rate and low pathogenicity. There was no difference in MDR between the diarrheal (49/70) and healthy groups (15/24).@*CONCLUSION@#We developed a random forest (RF) prediction model of TEM.1 + baeR + mphA + mphB + QnrS1 + AAC.3-IId to identify MDR status, highlighting its potential for early resistance identification. The causes of MDR are likely mobile units transmitting the ARGs. In the future, we will continue to strengthen the monitoring of ARGs and MDR, and increase the number of strains to further verify the accuracy of the MDR markers.

ABSTRACT

Objective: In this study, we aimed to investigate the prevalence of low anterior resection syndrome (LARS) in patients who had survived for more than 5 years after sphincter-preserving surgery for rectal cancer and to analyze its relationship with postoperative time. Methods: This was a single-center, retrospective, cross-sectional study. The study cohort comprised patients who had survived for at least 5 years (60 months) after undergoing sphincter- preserving radical resection of pathologically diagnosed rectal adenocarcinoma within 15 cm of the anal verge in the Department of Gastrointestinal Surgery, Peking University People's Hospital from January 2005 to May 2016. Patients who had undergone local resection, had permanent stomas, recurrent intestinal infection, local recurrence, history of previous anorectal surgery, or long- term preoperative defecation disorders were excluded. A LARS questionnaire was administered by telephone interview, points being allocated for incontinence for flatus (0-7 points), incontinence for liquid stools (0-3 points), frequency of bowel movements (0-5 points), clustering of stools (0-11 points), and urgency (0-16 points). The patients were allocated to three groups based on these scores: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). The prevalence of LARS and major LARS in patients who had survived more than 5 years after surgery, correlation between postoperative time and LARS score, and whether postoperative time was a risk factor for major LARS and LARS symptoms were analyzed. Results: The median follow-up time of the 160 patients who completed the telephone interview was 97 (60-193) months; 81 (50.6%) of them had LARS, comprising 34 (21.3%) with minor LARS and 47 (29.4%) with major LARS. Spearman correlation analysis showed no significant correlation between LARS score and postoperative time (correlation coefficient α=-0.016, P=0.832). Multivariate analysis identified anastomotic height (RR=0.850, P=0.022) and radiotherapy (RR=5.760, P<0.001) as independent risk factors for major LARS; whereas the postoperative time was not a significant risk factor (RR=1.003, P=0.598). The postoperative time was also not associated with LARS score rank and frequency of bowel movements, clustering, or urgency (P>0.05). However, the rates of incontinence for flatus (3/31, P=0.003) and incontinence for liquid stools (8/31, P=0.005) were lower in patients who had survived more than 10 years after surgery. Conclusions: Patients with rectal cancer who have survived more than 5 years after sphincter-preserving surgery still have a high prevalence of LARS. We found no evidence of major LARS symptoms resolving over time.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy between herbal-moxa plaster and moxa-box moxibustion for diarrhea type irritable bowel syndrome (IBS-D) of spleen and kidney yang deficiency.@*METHODS@#Eighty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a herbal-moxa plaster group and a moxa-box moxibustion group, 40 cases in each group. The patients in the two groups were treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 24+), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Yinlingquan (SP 9), and Taixi (KI 3), etc. In addition, the patients in the herbal-moxa plaster group were treated with herbal-moxa plaster (Wenyang Fuzheng ointment, composed of prepared monkshood, prepared evodia rutaecarpa, dried ginger, cinnamon, etc.) at Shenque (CV 8), Guanyuan (CV 4), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Shenshu (BL 23) and Shangjuxu (ST 37); the patients in the moxa-box moxibustion group were treated with moxa-box moxibustion at the same acupoints as the herbal-moxa plaster group. The acupuncture-moxibustion treatment was provided once every other day for 4 weeks (14 treatments). Before and after treatment, the scores of clinical symptom of TCM, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Compared with those before treatment, each item scores and total scores of clinical symptom of TCM, and IBS-SSS scores in the two groups were reduced after treatment (P<0.05). The abdominal bloating score, stool frequency score and total score of clinical symptom of TCM as well as IBS-SSS score in the herbal-moxa plaster group were lower than those in the moxa-box moxibustion group (P<0.05). Compared with those before treatment, the IBS-QOL scores in the two groups were increased after treatment (P<0.05), and the IBS-QOL score in the herbal-moxa plaster group was higher than that in the moxa-box moxibustion group (P<0.05). The total effective rate was 92.5% (37/40) in the herbal-moxa plaster group, which was higher than 85.0% (34/40) in the moxa-box moxibustion group (P<0.05).@*CONCLUSION@#On the basis of conventional acupuncture treatment, herbal-moxa plaster could effectively improve the clinical symptoms and quality of life in IBS-D patients of spleen and kidney yang deficiency, and its efficacy is superior to that of moxa-box moxibustion.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of electroacupuncture (EA) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated with gastrointestinal dysfunction.@*METHODS@#A total of 100 patients with AECOPD complicated with gastrointestinal dysfunction were randomly divided into an EA group (50 cases, 2 cases dropped off, 1 case excluded) and a medication group (50 cases). Both groups were treated with symptomatic and supportive treatment such as low flow oxygen, nebulized inhalation of short-acting β2 agonist (SABA) or short-acting muscarinic antagonist (SAMA) combined with inhaled corticosteroid (ICS). The EA group was treated with EA at Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Shuifen (CV 9), Tianshu (ST 25), Chize (LU 5) and Lieque (LU 7), with discontinuous wave, 2 Hz in frequency, 30 min each time, once a day. In the medication group, oral mosapride citrate tablets were given, 3 times a day, 5 mg each time. Both groups were treated for 5 d. Before and after treatment, the gastrointestinal symptom rating scale (GSRS) score was observe, serum procalcitonin (PCT), C-reactive protein (CRP), and plasma oxygenation index (PaO2/FiO2) were detected, and patient satisfaction degree was evaluated in the two groups.@*RESULTS@#Compared with before treatment, except for diarrhea dimension in the medication group, the total scores and each dimension scores of GSRS were decreased (P<0.05), serum PCT and CRP were decreased (P<0.05), plasma PaO2/FiO2 was increased (P<0.05) in the two groups after treatment. After treatment, in the EA group, the total score and abdominal pain, dyspepsia, constipation and diarrhea scores of GSRS were lower than those in the medication group (P<0.05), meanwhile serum PCT and CRP were lower and plasma PaO2/FiO2 was higher than those in the medication group (P<0.05). The improvement of gastrointestinal symptoms, life quality and overall satisfaction degree in the EA group were superior to those in the medication group (P<0.05).@*CONCLUSION@#EA could improve the symptoms of patients with AECOPD complicated with gastrointestinal dysfunction, reduce inflammatory response, improve oxygenation and patient satisfaction degree.

ABSTRACT

Objective: To explore disease characteristics of primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) and compare the differences between PSC with and without IBD. Methods: Study design was cross sectional. Forty-two patients with PSC who were admitted from January 2000 to January 2021 were included. We analyzed their demographic characteristics, clinical manifestations, concomitant diseases, auxiliary examination, and treatment. Results: The 42 patients were 11-74(43±18) years of age at diagnosis. The concordance rate of PSC with IBD was 33.3%, and the age at PSC with IBD diagnosis was 12-63(42±17) years. PSC patients with IBD had higher incidences of diarrhea and lower incidences of jaundice and fatigue than in those without IBD (all P<0.05). Alanine aminotransferase, total bilirubin, direct bilirubin, total bile acid and carbohydrate antigen 19-9 levels were higher in PSC patients without IBD than in those with IBD (all P<0.05). The positive rates for antinuclear antibodies and fecal occult blood were higher in PSC patients with IBD than in those without IBD (all P<0.05). Patients with PSC complicated with ulcerative colitis mainly experienced extensive colonic involvement. The proportion of 5-aminosalicylic acid and glucocorticoid application in PSC patients with IBD was significantly increased compared with that of PSC patients without IBD (P=0.025). Conclusions: The concordance rate of PSC with IBD is lower at Peking Union Medical College Hospital than in Western countries. Colonoscopy screening may benefit PSC patients with diarrhea or fecal occult blood-positive for early detection and diagnosis of IBD.

ABSTRACT

Objective: To analyze the short-time efficacy of empagliflozin in the treatment of glycogen storage disease type Ⅰb (GSD Ⅰb). Methods: In this prospective open-label single-arm study, the data of 4 patients were collected from the pediatric department in Peking Union Medical College Hospital from December 2020 to December 2022. All of them were diagnosed by gene sequencing and had neutropenia. These patients received empagliflozin treatment. Their clinical symptoms such as height and weight increase, abdominal pain, diarrhea, oral ulcer, infection times, and drug applications were recorded at 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 12 months, and 15 months after treatment to assess the therapeutic effect. The liquid chromatography-tandem mass spectrometry method was used to monitor the changes in 1, 5-anhydroglucitol (1, 5AG) concentration in plasma. At the same time, adverse reactions such as hypoglycemia and urinary tract infection were closely followed up and monitored. Results: The 4 patients with GSD Ⅰb were 15, 14, 4 and 14 years old, respectively at the beginning of empagliflozin treatment, and were followed up for 15, 15, 12 and 6 months, respectively. Maintenance dose range of empagliflozin was 0.24-0.39 mg/(kg·d). The frequency of diarrhea and abdominal pain decreased in cases 2, 3, and 4 at 1, 2 and 3 months of treatment, respectively. Their height and weight increased at different degrees.The absolute count of neutrophils increased from 0.84×109, 0.50×109, 0.48×109, 0.48×109/L to 1.48×109, 3.04×109, 1.10×109, 0.73×109/L, respectively. Granulocyte colony-stimulating factor was gradually reduced in 1 patients and stopped in 3 patient. Plasma 1, 5 AG levels in 2 children were significantly decreased after administration of empagliflozin (from 46.3 mg/L to 9.6 mg/L in case 2, and from 56.1 mg/L to 15.0 mg/L in case 3). All 4 patients had no adverse reactions such as hypoglycemia, abnormal liver or kidney function, or urinary system infection. Conclusion: In short-term observation, empagliflozin can improve the symptoms of GSD Ⅰb oral ulcers, abdominal pain, diarrhea, and recurrent infection, also can alleviate neutropenia and decrease 1, 5AG concentration in plasma, with favorable safety.

ABSTRACT

Objective: We analyze the characteristics of Clostridioides difficile (C. difficile) infection among diarrhea patients in Kunming from 2018 to 2020 and provide evidence for follow-up surveillance and prevention. Methods: A total of 388 fecal samples of diarrhea patients from four sentinel hospitals in Yunnan Province from 2018 to 2020 were collected. Real-time quantitative PCR was used to detect the fecal toxin genes of C. difficile. The positive fecal samples isolated the bacteria, and isolates were identified by mass spectrometry. The genomic DNA of the strains was extracted for multi-locus sequence typing (MLST). The fecal toxin, strain isolation, and clinical patient characteristics, including co-infection with other pathogens, were analyzed. Results: Among the 388 fecal samples, 47 samples with positive reference genes of C. difficile were positive, with a total positive rate of 12.11%. There were 4 (8.51%) non-toxigenic and 43 (91.49%) toxigenic ones. A total of 18 strains C. difficile were isolated from 47 positive specimens, and the isolation rate of positive specimens was 38.30%. Among them, 14 strains were positive for tcdA, tcdB, tcdC, tcdR, and tcdE. All 18 strains of C. difficile were negative for binary toxins. The MLST results showed 10 sequence types (ST), including 5 strains of ST37, accounting for 27.78%; 2 strains of ST129, ST3, ST54, and ST2, respectively; and 1 strain of ST35, ST532, ST48, ST27, and ST39, respectively. Fecal toxin gene positive (tcdB+) results were statistically associated with the patient's age group and with or without fever before the visit; positive isolates were only statistically associated with the patient's age group. In addition, some C. difficile patients have co-infection with other diarrhea-related viruses. Conclusions: The infection of C. difficile in diarrhea patients in Kunming is mostly toxigenic strains, and the high diversity of strains was identified using the MLST method. Therefore, the surveillance and prevention of C. difficile should be strengthened.
