Importancia de la interacción médico-paciente con enfermedad inflamatoria intestinal

Preferencias terapéuticas de los pacientes con enfermedad de Crohn: desarrollo del cuestionario IMPLICA

Introduction and objective: Patient preferences with respect to available therapies must be taken into account if the quality of care of patients with Crohn's disease is to be improved. The objective was to develop the IMPLICA preferences questionnaire for Crohn's disease patients treated with biological therapies. Methods: As per standard methodology, the questionnaire was developed in Spanish language, in five stages: 1. Literature review to identify attributes related to biological therapies in Crohn's disease; 2. Expert meeting to identify attributes most relevant for patients; 3. Scoring of the most relevant attributes and generation of scenarios; 4. Patient comprehension test for selection and validation of scenarios; and 5. Final list of scenarios and qualitative evaluation of those most accepted by patients. Results: Three attributes related to various characteristics of biological treatments were selected: route of administration, place/duration of administration and person administering the treatment; a combination of them produced seven possible scenarios. The comprehension test gave rise to significant modifications in the instructions, text of the scenarios and response categories. Conclusion: IMPLICA is the first questionnaire to evaluate treatment preferences of Crohn's disease patients receiving biological therapies. This questionnaire facilitates patient's selection of the most appropriate real world treatment option and, therefore, it can be considered a useful tool when deciding the most appropriate and feasible treatment in normal clinical practice.

Test de tolerancia a la lactosa reducido a 30 minutos: un estudio exploratorio de su factibilidad e impacto

Introduction: Lactose malabsorption (LM) is a very common condition with a high prevalence in our setting. Lactose tolerance test (LTT) is a basic, affordable test for diagnosis that requires no complex technology. It has been recently shown that this test can be shortened to 3 measurements (baseline, 30 min, 60 min) with no impact on final results. The purpose of our study was to assess the feasibility and benefits of LTT simplification and shortening to 30 min, as well as the financial impact entailed. Material and methods: A multicenter, observational study of consecutive patients undergoing LTT for LM suspicion. Patients received 50 g of lactose following a fasting period of 12 h, and had blood collected from a vein at all 3 time points for the measurement of blood glucose (mg/dl). Differences between the shortened and complete test forms were analyzed using McNemar's test. A comparison of blood glucose levels between patients with normal and abnormal results was performed using Student's T-test for independent mean values. Consistency was assessed using the kappa index. A p < 0.05 was considered to be statistically significant. Results: A total of 270 patients (69.6% females) were included, with a mean age of 39.9 ± 16 years. LTT was abnormal for 151 patients (55.9%). We observed no statistically significant differences in baseline blood glucose levels between patients with normal and abnormal LTT results (p = 0.13); however, as was to be expected, such differences were obvious for the remaining time points (p < 0.01). Deleting blood glucose measurements at 60 minutes only led to overdiagnose LM (false positive results) in 6 patients (2.22 %), with a kappa index of 0.95 (95% CI: 0.92-0.99) (p < 0.001) versus the complete test. Suppressing measurements at 60 min would have saved at least € 7,726. Conclusion: The shortening of LTT to only 2 measurements (baseline and 30-min) hardly leads to any differences in final results, and would entail savings in time, materials, and personnel.

Introducción: la malabsorción a la lactosa (ML) es una patología muy frecuente con alta prevalencia en nuestro medio. El test de tolerancia a la lactosa (TTL) es una prueba básica y económica que permite su diagnóstico sin precisar tecnología compleja. Recientemente se ha demostrado que este test puede reducirse a 3 determinaciones (basal, 30 y 60 min) sin afectar al resultado final. El propósito de nuestro estudio fue el valorar la factibilidad y ventajas de poder acortar y simplificar el TTL a 30 min, así como el impacto económico que conllevaría. Material y métodos: estudio multicéntrico y observacional de pacientes consecutivos a los que se les realiza un TTL ante la sospecha de ML. Los enfermos reciben 50 g de lactosa tras 12 h de ayuno y se les realiza extracción de sangre venosa en los 3 tiempos para la medición de la glucemia (mg/dl). La diferencia entre el test reducido y el completo se analizaron con el test de McNemar. La comparación de los niveles de glucemia entre los pacientes con test normal y patológico fue realizada usando el test t-Student para comparación de medias independientes. La concordancia fue evaluada con el índice Kappa. Se consideró p < 0,05 como estadísticamente significativo. Resultados: se incluyeron 270 pacientes (69,6 % mujeres) con edad media de 39,9 ± 16 años. El TTL fue patológico en 151 casos (55,9 %). No observamos diferencias estadísticamente significativas entre las glucemias basales de los pacientes con TTL normal o patológico (p = 0,13), sin embargo, como cabía esperar, estas diferencias fueron evidentes en los demás tiempos (p < 0,01). La eliminación de la determinación de glucemia a los 60 min tan solo sobrevaloró el diagnóstico de ML (falsos positivos) en 6 enfermos (2,22 %), con índice kappa de 0,95 (IC 95 %: 0,92-0,99) (p < 0.001) respecto al test completo. Si se hubiera suprimido la determinación de los 60 min, se podría haber ahorrado al menos 7.726 euros. Conclusión: el reducir el TTL a 2 determinaciones (basal y 30 min) no implica apenas cambios en el resultado final del test, sin embargo conllevaría un ahorro de tiempo, material y personal.

Adaptación transcultural y validación al español del "Adult Eosinophilic Esophagitis Quality of Life Questionnaire"

Background: The "Adult Eosinophilic Esophagitis Quality of Life (EoE-QoL-A) Questionnaire" was developed in English as a valid, reliable, and disease-specific health-related QoL measure. This research aims to adapt and validate this questionnaire for Spanish-speaking patients. Patients and methods: A multicenter, observational, prospective study was conducted at 8 Spanish hospitals. The cultural adaptation of the original EoE-QoL-A questionnaire was undertaken through a standardized 3-phase procedure: 1. Translation; 2. Retrotranslation; and 3. Pilot study. Patients completed the Hospital Anxiety and Depression Scale (HADS), the Short Form (SF)-12, the Brief Illness Perception Questionnaire (BIPQ), and the adapted EoE-QoL-A, with a retest 3 months later. Statistical analysis included construct validity, internal consistency, criterion validity, and reproducibility. Results: One hundred and seventy adult EoE patients (73.5 % male; aged 33.5 ± 11.4-y) were included in the study. With regard to internal validity, all Cronbach alpha values were > 0.75. A significant correlation between items assessed in the SF-12, BIPQ and EoE-QoL-A questionnaires (p < 0.001) was observed. Correlations with the HADS were stronger for anxiety than for depression levels. Anxiety related to disease diagnosis and choking were the most affected dimensions; less affected were the dimensions related to eating, social, and emotional development. Intraclass correlation coefficients between the test and retest assessments were acceptable for all questionnaires, with the highest values (0.73-0.84) calculated for the EoE-QoL-A Spanish version. Conclusion: The Spanish version of the EoE-QoL-A is a reliable, valid, and responsive questionnaire. Diagnosis and choking anxiety were the most affected dimensions in the health-related QoL in adult EoE patients.

Utilidad de la ecografía abdominal en el diagnóstico y seguimiento de la enfermedad inflamatoria intestinal

Abdominal ultrasonography has been undervalued for years as technique used in examining the gastrointestinal tract. However, thanks to the technological advances that have been seen in ultrasonography probes and the use of high frequency equipment, we are able to obtain high quality images of the intestinal wall. Moreover, due to the increased sensitivity of the colour Doppler, we can detect the parietal vascularization. Finally, in recent years, intravenous ultrasonography contrast agents have been used that allow not only the inflammatory activity to be quantified but also the presence of complications with a diagnostic accuracy similar to computed tomography (CT) and full magnetic resonance (full-RM), without the associated radiation risk and at a lower cost. This article reviews the utility of abdominal ultrasonography in inflammatory bowel disease, in particular Crohn's disease, both during initial diagnosis and follow-up of the disease; the article also reviews the ability of the technique to be used in the detection of complications (stenosis, fistulas and abscesses).

La ecografía abdominal ha sido una técnica infravalorada durante años para evaluar el tubo digestivo. Sin embargo, gracias al avance tecnológico que han experimentado los equipos ecográficos y al uso de sondas de alta frecuencia somos capaces de obtener imágenes de alta calidad de la pared intestinal. Por otra parte, debido al aumento de la sensibilidad del Doppler color podemos detectar la vascularización parietal. Finalmente, en los últimos años se están utilizando los contrastes ecográficos intravenosos que permiten no solo cuantificar la actividad inflamatoria, sino también detectar la presencia de complicaciones con una fiabilidad diagnóstica similar a la tomografía computarizada (TC) y la enterorresonancia magnética (entero-RM) sin riesgo de radiación y a un coste menor. En este artículo se hace una revisión de la utilidad de la ecografía abdominal en la enfermedad inflamatoria intestinal, especialmente en la enfermedad de Crohn, tanto en el diagnóstico inicial como durante el seguimiento de la enfermedad, así como de la capacidad de la técnica en la detección de complicaciones (estenosis, fístulas y abscesos).

Pseudodiverticulosis esofágica intramural: una causa poco frecuente de disfagia

Tratamiento endoscópico de enfermedades comunes con un nuevo sistema de sutura

Background: Overstitch endoscopic suturing system (Apollo Endosurgery. Austin, Texas) was created for NOTES procedures. As it demonstrated to be feasible, secure and effective in this field, further studies have evaluated its use in common gastrointestinal disorders in which current therapeutic tools, endoscopic or not, are not efficient or safe enough. Published results are promising. We present our initial experience with this system in the management of pathologies we usually face in our clinical practice. Method: Suturing system was evaluated for: 1. Endoscopic fixation of metallic stent to prevent migration in patients with gastrointestinal non-neoformative pathology. 2. Outlet reduction in patients with weight regain following Roux-en-Y gastric bypass. Results: During a period of 6 months Overstitch endoscopic suturing system was used in 5 patients: For stent fixation in 3 and for outlet reduction in 2. Technical success: Suture was performed in all the patients. Only 1 stitch was lost. Effectiveness: Stent fixation and outlet reduction were achieved in all the patients. However, in 1 patient the final anastomotic size was not close enough. Clinical success: Clinical recovery was achieved in all the patients in whom endoscopic stent fixation was performed. The patient which appropriated outlet closure developed a significant weight loss. The patient in which final size was not close enough did not lose weight. Conclusions: We found Overstitch endoscopic suturing system feasible, safe and effective, as it has been previously described. We encourage the publication of further studies evaluating the real utility of this tool, mostly taking into account that it allows a successful management of usual disorders for which there are not current effective therapies.

Gastritis flemonosa: una entidad poco frecuente como diagnóstico diferencial del abdomen agudo. Descripción de un caso y revisión bibliográfica

Phlegmonous gastritis is a rare bacterial infection of the gastric wall, which progress rapidly. It is characterized by a purulent inflammation that can affect the entire gastrointestinal tract and presents a high mortality rate. We are reporting a case of phlegmonous gastritis in an HIV-seropositive man successfully treated with antibiotics. Moreover, a review of the English and Spanish literature is carried out, from 1980 to the present time. The most frequently involved microorganism is Streptococcus spp. (57 %), but the polimicrobial infection is also frequent (17 %). The most important symptom is the intensive epigastric pain associated with vomits and most cases were diagnosed by CT and/or fibrogastroscopy. There are many existing risk factors described. The main one is the immunesuppression, although in 40 % of the cases no risk factors were identified. The global mortality is 27 % without identifying significant differences between antibiotics and surgical treatment, for that reason it is recommended to initiate antibiotic treatment right from the beginning and postponing surgery for the refractory cases and complications.

La gastritis flemonosa es una infección bacteriana poco frecuente y rápidamente progresiva de la pared gástrica. Se caracteriza por una inflamación purulenta que puede afectar a todo el tracto gastrointestinal y que presenta un índice elevado de mortalidad. En este trabajo se comunica un caso de gastritis flemonosa en un paciente seropositivo para la infección por VIH tratado exitosamente con antibioticoterapia. Además, se realiza una revisión de los casos publicados en la bibliografía médica, en inglés y español desde 1980 hasta la actualidad. El microorganismo más frecuentemente implicado es Streptococcus spp. (57 %), pero también destaca la infección polimicrobiana (17 %). El síntoma más común es el dolor epigástrico intenso asociado a vómitos y la mayoría de casos fueron diagnosticados mediante TC y/o endoscopia. Existen numerosos factores de riesgo descritos, el principal es la inmunosupresión, aunque en el 40 % de los casos no se identificó ningún factor de riesgo. La mortalidad global es del 27 %, sin identificar diferencias significativas entre el tratamiento antibiótico y quirúrgico, por lo que se recomienda instaurar el tratamiento antibiótico de manera precoz y reservar la cirugía para los casos refractarios y las complicaciones.
