Sensitivity and specificity of three diabetes diagnostic criteria in people with non-alcoholic fatty liver disease (NAFLD) and otherwise healthy people: Analysis of NHANES III.

AIMS: Establishing whether fasting plasma glucose (FPG), postprandial glucose (PPG), and HbA1c have the same diagnostic accuracy in NAFLD versus otherwise healthy people could inform T2DM screening recommendations for those with NAFLD. METHODS: Cross-sectional analysis of the Third National Health and Nutrition Examination Survey (NHANES III) 1989-1994. T2DM was defined as PPG ≥ 200 mg/dL, FPG ≥ 126 mg/dL, or HbA1c ≥ 6.5 %. We estimated sensitivity and specificity between the six pairwise combinations between the three T2DM definitions in people with and without NAFLD. With Poisson regressions, we investigated if people with NAFLD were more likely to have T2DM with two diagnostic criteria yet not with the third one. RESULTS: There were 3652 people with mean age 55.6 years and 49.4 % were men; 673 (18.4 %) people had NAFLD. Compared to NAFLD-free individuals, those with NAFLD had lower specificity in all pairwise comparisons except when PPG was the reference vs HbA1c [98.28 % (95 % CI: 97.73 %-98.72 %) in people without NAFLD vs 96.15 % (95 % CI: 94.28 %-97.54 %)]. The sensitivity of FPG was slightly superior to PPG and HbA1c in people without NAFLD; for example, 64.62 % (95 % CI: 55.75 %-72.80 %) for FPG vs 56.58 % (95 % CI: 44.71 %-67.92 %) for HbA1c. People with NAFLD were more likely to be diagnosed with FPG and PPG yet not with HbA1c (PR=2.15; p = 0.020). CONCLUSIONS: While these T2DM diagnostic criteria may capture different patients both in people with and without NAFLD, in the NAFLD population FPG appears to have the best sensitivity and there were no differences between PPG and HbA1c in terms of specificity.

Adverse reactions to antituberculosis drugs presenting as DRESS syndrome and acute liver failure.

Drug induced liver injury (DILI) can be can be triggered by many medications including antituberculosis drugs. We present the case of a 37-year-old woman with a smear- positive pulmonary tuberculosis who started treatment with first-line antituberculosis drugs and 4 weeks later presented jaundice, somnolence and a morbilliform generalized rash with progressive neurologic deterioration which had a fatal outcome. Antituberculosis drugs can cause DILI in 2 to 28% of patients and drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) in 1.2%. Acute liver failure (ALF) can occur in 35% of patients with DILI with an overall mortality of 9.7%. If the ALF is unresponsive to medical treatment, liver transplantation has shown promising results and can avoid progression of complications. DILI can be a serious medical condition in patients receiving antituberculosis drugs. If ALF develops and is unresponsive to medical treatment, liver transplantation should be considered as the treatment of choice.

Phenotypes of non-alcoholic fatty liver disease (NAFLD) and all-cause mortality: unsupervised machine learning analysis of NHANES III.

OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is a non-communicable disease with a rising prevalence worldwide and with large burden for patients and health systems. To date, the presence of unique phenotypes in patients with NAFLD has not been studied, and their identification could inform precision medicine and public health with pragmatic implications in personalised management and care for patients with NAFLD. DESIGN: Cross-sectional and prospective (up to 31 December 2019) analysis of National Health and Nutrition Examination Survey III (1988-1994). PRIMARY AND SECONDARY OUTCOMES MEASURES: NAFLD diagnosis was based on liver ultrasound. The following predictors informed an unsupervised machine learning algorithm (k-means): body mass index, waist circumference, systolic blood pressure (SBP), plasma glucose, total cholesterol, triglycerides, liver enzymes alanine aminotransferase, aspartate aminotransferase and gamma glutamyl transferase. We summarised (means) and compared the predictors across clusters. We used Cox proportional hazard models to quantify the all-cause mortality risk associated with each cluster. RESULTS: 1652 patients with NAFLD (mean age 47.2 years and 51.5% women) were grouped into 3 clusters: anthro-SBP-glucose (6.36%; highest levels of anthropometrics, SBP and glucose), lipid-liver (10.35%; highest levels of lipid and liver enzymes) and average (83.29%; predictors at average levels). Compared with the average phenotype, the anthro-SBP-glucose phenotype had higher all-cause mortality risk (aHR=2.88; 95% CI: 2.26 to 3.67); the lipid-liver phenotype was not associated with higher all-cause mortality risk (aHR=1.11; 95% CI: 0.86 to 1.42). CONCLUSIONS: There is heterogeneity in patients with NAFLD, whom can be divided into three phenotypes with different mortality risk. These phenotypes could guide specific interventions and management plans, thus advancing precision medicine and public health for patients with NAFLD.

La injuria hepática inducida por fármacos (IHIF) puede ser desencadenado por varios medicamentos incluyendo fármacos anti tuberculosos. Presentamos el caso de una paciente mujer de 37 años con un frotis positivo para tuberculosis pulmonar quien inició tratamiento de primera línea y 4 semanas después, presentó ictericia, somnolencia y un exantema generalizado de tipo morbiliforme con deterioro neurológico progresivo y un desenlace fatal. Los fármacos anti tuberculosos pueden producir injuria inducida por fármacos en 2 a 28% de pacientes y síndrome de DRESS (reacción de sensibilidad a medicamentos con eosinofilia y síntomas sistémicos) en 1,2%. La falla hepática aguda (FHA) en pacientes con injuria hepática inducida por fármacos, puede presentarse en un 35% con una mortalidad del 9,7%. Si la FHA no responde a tratamiento médico, el trasplante hepático ha mostrado resultados positivos y evita la progresión de complicaciones. La IHIF puede ser una condición médica grave en pacientes que reciben medicamentos antituberculosos. Si se desencadena una FHA y no responde a tratamiento médico, debe considerarse con urgencia la posibilidad de trasplante hepático.

Epidemiology and associated factors of irritable bowel syndrome in an Andean community from Peru.

INTRODUCTION: Irritable bowel syndrome (IBS) is a chronic functional bowel condition with an average world prevalence of 11.2%. Is associated with multiple factors as female sex, young age, stress, anxiety and depression which can have a negative impact on quality of life. IBS in Peru is not investigated at all specially in the Andean region. The objective of this study is to determine the prevalence and associated factors of IBS in an Andean community from Peru using the Rome IV criteria. MATERIALS AND METHODS: Cross-sectional study in a rural community dedicated to livestock and agriculture in Peru at 3,235 meters above sea level. Questionnaires provided by the Rome Foundation as the Rome IV - Diagnostic questionnaire for adults, Irritable Bowel Syndrome - Symptom Severity Scale and Bristol stool scale were used. RESULTS: 130 residents met the inclusion criteria. 46.9% were males with an average age of 54 years old. 11.54% presented red flags and were not included in the analysis. 13.1% were diagnosed with IBS and 52.9% presented constipation as predominant bowel pattern. 52.9% presented a mild course of the disease. In the chi-square analysis, factors as depression, anxiety, female sex, younger age, liquefied petroleum gas exposure for cooking and education achievement were statistically significant associated to IBS. In the logistic regression analysis, anxiety was the unique independent predictor factor with an OR of 9.6 (95% IC: 1.78-51.82). CONCLUSION: IBS is a prevalent condition in the Andean region and should be managed as a public health issue to improve quality of life.

Laparoscopic splenectomy and proximal splenorenal shunt for portal hypertension due to portal vein thrombosis in a patient with protein S deficiency.

Portal vein thrombosis (PVT) is a rare condition in the general population that develops serious complications if left untreated for long time. We present a case of a 29-year-old woman who developed PVT due to protein S deficiency versus neonatal funiculitis. Over time, the patient developed upper gastrointestinal bleeding due to esophageal varices and hypersplenism with splenic sequestration that caused minor bleeding episodes. Laparoscopic splenectomy and proximal splenorenal shunt with distal pancreatectomy due to aneurysmal dilatations of the splenic artery were successfully performed to avoid mayor progression of portal hypertension. Patient was discharged with indefinite anticoagulation and after surgery platelets raised up to 200x103/mm3. Laparoscopic splenectomy and proximal splenorenal shunt for portal hypertension due to portal vein thrombosis is an adequate surgery procedure which should be applied in these medical cases.

Endoscopic removal of a toothbrush in a young adult with psychiatric disorder / Extracción endoscópica de un cepillo de dientes en un adulto joven con trastorno psiquiátrico

ABSTRACT Ingestion of foreign bodies is a relative common situation in the emergency department; however, ingestion of toothbrush is rarely reported in the literature. We present the case of a 27-year-old man with a previous diagnosis of obsessive-compulsive disorder, who presented to the emergency department 17 hours after an ingestion of a toothbrush. We performed an endoscopic removal using a polypectomy snare in the Gastroenterology Department under moderate sedation. No complications were reported in the procedure and the patient was discharged few hours later. Ingestion of toothbrush is rare in the literature and some authors described techniques using overtube and retractable snares and forceps. Endoscopic removal of a toothbrush under moderate sedation can be a safe and successful procedure. However, if endoscopic removal fails, surgery should be performed.

RESUMEN La ingestión de cuerpos extraños es una situación relativamente común en el departamento de emergencias; sin embargo, la ingestión de cepillo de dientes rara vez se informa en la literatura. Presentamos el caso de un varón de 27 años con diagnóstico previo de trastorno obsesivo compulsivo, que acudió al servicio de urgencias 17 horas después de la ingestión de un cepillo de dientes. Realizamos una extirpación endoscópica usando un asa de polipectomía en el Servicio de Gastroenterología bajo sedación moderada. No se reportaron complicaciones en el procedimiento y el paciente fue dado de alta pocas horas después. La ingestión de cepillo de dientes es rara en la literatura y algunos autores describen técnicas que utilizan sobretubo y asas y fórceps retráctiles. La extracción endoscópica de un cepillo de dientes bajo sedación moderada puede ser un procedimiento seguro y exitoso. Sin embargo, si la extracción endoscópica falla, se debe realizar una cirugía.

Introducción : El síndrome del intestino irritable (SII) es una enfermedad intestinal funcional crónica con una prevalencia mundial promedio del 11,2%. Se asocia a múltiples factores como el sexo femenino, la juventud, el estrés, la ansiedad y la depresión que pueden tener un impacto negativo en la calidad de vida. El SII en Perú, no es investigado a profundidad, especialmente en la región andina. El objetivo de este estudio es determinar la prevalencia y factores asociados del SII en una comunidad andina de Perú utilizando los criterios de Roma IV. Materiales y métodos : Estudio transversal en una comunidad rural dedicada a la ganadería y la agricultura en Perú a 3 235 metros sobre el nivel del mar. Se utilizaron cuestionarios proporcionados por la Fundación de Roma como Rome IV - Cuestionario de diagnóstico para adultos, Síndrome del intestino irritable - Escala de gravedad de los síntomas y Escala de heces de Bristol. Resultados : 130 residentes cumplieron los criterios de inclusión. El 46,9% eran varones con una edad media de 54 años. El 11,54% presentó señales de alerta y no fueron incluidos en el análisis. El 13,1% fueron diagnosticados de SII y el 52,9% presentó estreñimiento como patrón intestinal predominante. El 52,9% presentó un curso leve de la enfermedad. En el análisis de chi-cuadrado, factores como depresión, ansiedad, sexo femenino, edad más joven, exposición a gas licuado de petróleo para cocinar y logros educativos fueron estadísticamente significativos asociados con el SII. En el análisis de regresión logística, la ansiedad fue el único factor predictor independiente con una OR de 9,6 (IC del 95%: 1,78-51,82). Conclusión : El SII es una condición prevalente en la región andina y debe ser manejado como un problema de salud pública para mejorar la calidad de vida.

La trombosis de la vena porta (TVP) es una afección poco común en la población general que desarrolla complicaciones graves si no se trata durante mucho tiempo. Presentamos el caso de una mujer de 29 años que desarrolló TVP por deficiencia de proteína S versus funiculitis neonatal. Con el tiempo, la paciente desarrolló hemorragia digestiva alta por varices esofágicas e hiperesplenismo con secuestro esplénico que provocó episodios hemorrágicos menores. La esplenectomía laparoscópica y la derivación esplenorrenal proximal con pancreatectomía distal por dilataciones aneurismáticas de la arteria esplénica se realizaron con éxito para evitar una mayor progresión de la hipertensión portal. La paciente fue dada de alta con anticoagulación indefinida y tras la cirugía se elevaron las plaquetas hasta 200x103/mm3. La esplenectomía laparoscópica y la derivación esplenorrenal proximal para la hipertensión portal por trombosis de la vena porta es un procedimiento quirúrgico adecuado que debe aplicarse en estos casos médicos.
