Spanish Intragastric Balloon Consensus Statement (SIBC): practical guidelines based on experience of over 20 000 cases.

BACKGROUND: intragastric balloons (IGBs) are a minimally invasive, increasingly popular option for obesity treatment. However, there is only one worldwide guideline standardizing the technical aspects of the procedure (BIBC, SOARD 2018). OBJECTIVES: to construct a practical guideline for IGB usage by reproducing and expanding the BIBC survey among the Spanish Bariatric Endoscopy Group (GETTEMO). METHODS: a 140-question survey was submitted to all GETTEMO members. Twenty-one Spanish experienced endoscopists in IGBs answered back. Eight topics on patient selection, indications/contraindications, technique, multidisciplinary follow-up, results, safety, and financial/legal aspects were discussed. Consensus was defined as consensus ≥ 70 %. RESULTS: overall data included 20 680 IGBs including 12 different models. Mean age was 42.0 years-old, 79.9 % were women, and the mean preoperative body mass index (BMI) was 34.05 kg/m². Indication in BMI > 25 kg/m², 10 absolute contraindications, and nutritional and medication measures at follow-up were settled. A mean %TBWL (total body weight loss) of 17.66 % ± 2.5 % was observed. Early removal rate due to intolerance was 3.62 %. Adverse event rate was 0.70 % and 6.37 % for major and minor complications with consensual management. A single case of mortality occurred. IGBs were placed in private health, prior contract, and with full and single payment at the beginning. Seven lawsuits (0.034 %) were received, all ran through civil proceeding, and with favorable final resolution. CONCLUSIONS: this consensus based on more than 20 000 cases represents practical recommendations to perform IGB procedures. This experience shows that the device leads to satisfactory weight loss with a low rate of adverse events. Most results are reproducible compared to those obtained by the BIBC.

European Registry on Helicobacter pylori Management: Effectiveness of First and Second-Line Treatment in Spain.

The management of Helicobacter pylori infection has to rely on previous local effectiveness due to the geographical variability of antibiotic resistance. The aim of this study was to evaluate the effectiveness of first and second-line H. pylori treatment in Spain, where the empirical prescription is recommended. A multicentre prospective non-interventional registry of the clinical practice of European gastroenterologists concerning H. pylori infection (Hp-EuReg) was developed, including patients from 2013 until June 2019. Effectiveness was evaluated descriptively and through a multivariate analysis concerning age, gender, presence of ulcer, proton-pump inhibitor (PPI) dose, therapy duration and compliance. Overall, 53 Spanish hospitals were included, and 10,267 patients received a first-line therapy. The best results were obtained with the 10-day bismuth single-capsule therapy (95% cure rate by intention-to-treat) and with both the 14-day bismuth-clarithromycin quadruple (PPI-bismuth-clarithromycin-amoxicillin, 91%) and the 14-day non-bismuth quadruple concomitant (PPI-clarithromycin-amoxicillin-metronidazole, 92%) therapies. Second-line therapies were prescribed to 2448 patients, with most-effective therapies being the triple quinolone (PPI-amoxicillin-levofloxacin/moxifloxacin) and the bismuth-levofloxacin quadruple schemes (PPI-bismuth-levofloxacin-amoxicillin) prescribed for 14 days (92%, 89% and 90% effectiveness, respectively), and the bismuth single-capsule (10 days, 88.5%). Compliance, longer duration and higher acid inhibition were associated with higher effectiveness. "Optimized" H. pylori therapies achieve over 90% success in Spain.

Combination of Bismuth and Standard Triple Therapy Eradicates Helicobacter pylori Infection in More than 90% of Patients.

BACKGROUND & AIMS: Due to the poor eradication rates of standard triple therapy, the addition of bismuth salts has been proposed for first-line eradication of Helicobacter pylori. We assessed the effectiveness and safety of the combination of bismuth and the standard, clarithromycin-containing triple therapy in eradication of H pylori infection, using data from a large multi-center registry. METHODS: We performed an interim analysis of data from the European Registry on H pylori Management, a prospective trial registering clinical data and outcomes from infected patients from 27 countries in Europe since 2013. We extracted data on 1141 treatment-naïve patients who received first-line treatment with bismuth salts (240 mg) and a proton pump inhibitor (57% received esomeprazole, 18% received omeprazole, 11% received pantoprazole, and 14% received rabeprazole), amoxicillin (1 g), and clarithromycin (500 mg), all taken twice daily. RESULTS: Intention to treat and per-protocol rates of eradication were 88% and 94%, respectively. Intention to treat eradication increased to 93% in patients who received 14-day treatments. Adverse events occurred in 36% of patients; 76% of these events were mild, with a mean duration of 6 days. In multivariate analysis, eradication was associated with treatment compliance (odds ratio [OR], 13.0), a double dose (equivalent to 40 mg omeprazole) of proton pump inhibitor (OR, 4.7), and 14-day duration of treatment (OR, 2.0). CONCLUSIONS: In an analysis of data from a large multi-center registry, we found the addition of bismuth to 14-day standard triple therapy with clarithromycin and amoxicillin to eradicate H pylori infection in more than 90% of patients, based on intention to treat analysis, with an acceptable safety profile and level of adherence.

Primary hypolactasia diagnosis: Comparison between the gaxilose test, shortened lactose tolerance test, and clinical parameters corresponding to the C/T-13910 polymorphism.

BACKGROUND & AIMS: There is no consensus on the most accurate method to diagnose primary hypolactasia. We aimed to compare the diagnostic accuracy of the new gaxilose test with 2 traditional tests (lactose tolerance test and clinical criteria) for the diagnosis of primary hypolactasia using the C/T-13910 polymorphism as a reference standard. METHODS: Patients with a clinical suspicion of lactose intolerance were subjected to gaxilose tests, shortened lactose tolerance tests, and symptom questionnaires before and after overload with 50 g lactose and after a lactose-free diet. The diagnostic accuracy and degree of agreement and correlation were assessed using a genetic test (C/T-13910 polymorphism) as a reference standard and their respective 95% confidence intervals. RESULTS: Thirty consecutive patients (70% women) participated in the study. The genetic test confirmed the C/T-13910 polymorphism in 11 patients (36.8%). The presence of diarrhoea and the symptom score after lactose overload, along with the tolerance test, were the variables with the highest degree of agreement (κ > 0.60). Area under the ROC curve was >0.82 (p < 0.05), with sensitivity and specificity values of >0.80. However, the gaxilose test obtained lower values: κ, 0.47; area under curve, 0.75 (0.57-0.94); sensitivity, 0.82 (0.55-1); and specificity, 0.68 (0.45-0.92). The multivariate analysis showed an association between the post-overload symptom questionnaire and the results of the genetic test (odds ratio: 1.17; 1.04-1.31; p < 0.01). CONCLUSIONS: The presence of diarrhoea and the symptom score after overload with 50 g lactose showed a higher degree of agreement and diagnostic accuracy for primary hypolactasia than the gaxilose test when the genetic test is used as a reference standard.

Correlation Between Capillary and Venous Blood Glucose in the Lactose Tolerance Test.

BACKGROUND: The lactose tolerance test is a classic method for the study of lactose malabsorption. However, the methodology used has not been standardized, and this leads to differences in results. AIM: The aim of this report was to analyze whether capillary blood glucose measurement is in agreement with venous blood glucose when performing lactose tolerance test. METHODS: This is a prospective study of consecutive patients with suspected lactose malabsorption who had lactose tolerance test performed in venous and capillary blood simultaneously, using a load of 50 g lactose. Agreement was measured using the concordance correlation coefficient of Lin (95 % CI) and Bland-Altman plots. The degree of agreement was measured using the Kappa index. A value of p < 0.05 was considered statistically significant. RESULTS: Eighty-four patients (68 % women) were included. The concordance correlation coefficient showed very poor agreement between the two techniques: 0.68 (0.58-0.77), 0.72 (0.62-0.8), and 0.77 (0.69-0.83) for baseline, 30, and 60 min, respectively. The Bland-Altman plots showed that capillary blood glucose measurements result in higher levels than venous blood glucose measurements, with mean differences of 0.39, 0.77, and 1.1 mmol/L at baseline, 30, and 60 min, respectively. The degree of agreement was low, with a Kappa index of 0.59 (p < 0.001). CONCLUSIONS: The test measured in venous blood is not in agreement with the measurement obtained from capillary blood. It is likely that the diagnostic accuracy attributed without distinction to lactose tolerance test in different studies for lactose malabsorption is incorrect, making it necessary to specify the analysis method.

The management of lactose intolerance among primary care physicians and its correlation with management by gastroenterologists: the SEPD-SEMG national survey.

INTRODUCTION AND AIMS: The understanding of lactose intolerance (LI) is limited in some professional settings. Sociedad Española de Patología Digestiva (SEPD) and Sociedad Española de Medicina General (SEMG) have developed a survey in order to: a) Analyze primary care physicians (PCPs) knowledge and clinical management; and b) to compare results with those of a previous survey of Spanish gastroenterologists (GEs). MATERIAL AND METHODS: An online questionnaire was sent to SEMG members with 27 items on various issues: Demographics, occupational characteristics, outlook on LI, diagnostic tests, treatment, and follow-up. Results were compared to those from a survey of GEs. RESULTS: A total of 456 PCPs responded, versus 477 GEs. PCPs had an older mean age and longer professional experience. Level of understanding of LI was similar, albeit a higher proportion of PCPs lacked epidemiological awareness (p < 0.01). GEs tended to consider LI a "minor" condition (71.3 vs. 40.1%; p > 0.001), and LI symptoms as overlapping those of irritable bowel syndrome (93.5 vs. 88.2%; p = 0.005), although symptoms perceived as suspicious of LI were similar in both groups. Dietary recommendations were recognized as the primary therapeutic approach. CONCLUSION: This study reveals the outlook of PCPs on LI, and allows comparison with that of GEs, as a basis for the development of strategies aimed at improving LI understanding, approach and management in our setting.

Manejo de la intolerancia a la lactosa entre los médicos de atención primaria y su correlación con la de los especialistas en digestivo: encuesta nacional SEPD-SEMG / The management of lactose intolerance among primary care physicians and its correlation with management by gastroenterologists: The SEPD-SEMG national survey

INTRODUCCIÓN Y OBJETIVOS: el conocimiento sobre la intolerancia a la lactosa (IL) es limitado en algunos ámbitos profesionales. La Sociedad Española de Patología Digestiva (SEPD) y la Sociedad Española de Medicina General (SEMG) han elaborado una encuesta con los objetivos de: a) analizar el nivel de conocimiento y de manejo clínico de los médicos de atención primaria (MAP); y b) comparar sus resultados con los de la encuesta ya realizada entre los gastroenterólogos españoles (GE). MATERIAL Y MÉTODOS: se envió un cuestionario online a los socios de la SEMG, con 27 preguntas sobre distintas cuestiones: demografía y características laborales, actitud frente a la IL, métodos de diagnóstico, tratamiento y seguimiento. Los resultados fueron comparados con los de la encuesta a GE. RESULTADOS: se recopilaron 456 respuestas de MAP, que se compararon con las proporcionadas por 477 GE. Los MAP presentaron una edad media y experiencia profesional mayor. El nivel de conocimiento sobre IL fue parecido, si bien una mayor proporción de MAP desconocía la epidemiología del problema (p < 0,01). Los GE tendieron a considerar a la IL una patología "menor" (71,3 vs. 40,1%; p > 0,001), y a sus síntomas superponibles a los del síndrome del intestino irritable (93,5 vs. 88,2%; p = 0,005), si bien los síntomas reconocidos como sospechosos de IL fueron similares entre ambos grupos. Las recomendaciones dietéticas fueron reconocidas como la principal medida terapéutica. CONCLUSIÓN: este estudio permite conocer la actuación de los MAP ante la IL y compararla con la de los GE, como base para el desarrollo estrategias para mejorar el conocimiento, actitud y tratamiento de la IL en nuestro medio

Lactose tolerance test shortened to 30 minutes: An exploratory study of its feasibility and impact.

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.

Test de tolerancia a la lactosa reducido a 30 minutos: un estudio exploratorio de su factibilidad e impacto / Lactose tolerance test shortened to 30 minutes: an exploratory study of its feasibility and impact

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 (AU)
