Potentially Inappropriate Prescriptions for Anticholinergic Medications for Patients with Constipation.

INTRODUCTION: Constipation is a very common functional gastrointestinal disorder in the general population and can be primary or secondary. OBJECTIVE: The aim of this study was to estimate the anticholinergic burden of prescribed drugs in a population diagnosed with constipation in Colombia. METHODS: This was a cross-sectional study that used a population database of 6.5 million people to identify the prescription of cholinergic antagonists and drugs for the management of constipation in outpatient services. The anticholinergic burden was evaluated using the Anticholinergic Drug Scale. Potentially inappropriate prescriptions that increased the risk of constipation were identified. RESULTS: A total of 3,887 patients with constipation were identified; the identified patients had a mean age of 54.4 ± 21.9 years, and 69.4% were women. Eighty percent received at least one laxative, and the most prescribed laxative was bisacodyl (50.5%). Forty-one percent (n = 1,586) of all patients received drugs with cholinergic antagonist activity, in particular codeine (6.5%) and valproic acid (6.5%). Being over 30 years of age (odds ratio [OR]: 1.79; 95% confidence interval [CI]: 1.24-2.57), being treated in the cities of Manizales (OR: 2.20; 95% CI: 1.50-3.21) and Pereira (OR: 1.49; 95% CI: 1.07-2.09), and having hypothyroidism as a comorbidity (OR: 1.37; 95% CI: 1.08-1.73) were associated with a greater probability of receiving medications with an anticholinergic burden of 3 or more points. CONCLUSIONS: The majority of patients with constipation were women and were using laxatives to manage constipation. A large proportion of patients were prescribed at least one cholinergic antagonist drug, with an increased probability of use after 30 years of age.

Patrones de prescripción de medicamentos antitiroideos en una población de Colombia / Patterns of prescription of antithyroid drugs in a Colombian population

Resumen Introducción: en Colombia no se conoce la prevalência de los trastornos asociados a tirotoxicosis ni se dispone de estudios fármacoepidemiológicos acerca de la prescripción de los medicamentos antitiroideos. Objetivo: determinar los patrones de prescripción de los antitiroideos y variables asociadas a su uso en una población de pacientes en Colombia. Métodos: estudio de corte transversal, realizado entre enero 1 y marzo 30 de 2015 sobre los hábitos de prescripción de medicamentos antitiroideos en una población afiliada al sistema de salud colombiano. Se midieron variables sociodemográficas, farmacológicas y de comedicación. Se diseñó una base de datos sobre el consumo de medicamentos y se utilizaron pruebas t de student, X 2 y modelos de regresión logística. Resultados: un total de 327 pacientes en tratamiento con medicamentos antitiroideos fueron incluidos. La edad media fue de 53.7±18.1 años y 78.3% de pacientes correspondió a mujeres. El metimazol se prescribió en 95.4% de los pacientes, el propiltiouracilo en 4.6%. En 76.8% de pacientes se presentó comedicación; en particular con antihipertensivos (38.2%) y adicionalmente con propranolol (34.3%). Conclusiones: la tendencia de prescripción de medicamentos antitiroideos en Colombia es similar a lo reportado en diferentes estudios a nivel mundial. El principal medicamento antitiroideo es metimazol, con una tasa de uso mayor a la reportada en Norteamérica y en estudios europeos. Las dosis del metimazol y de propiltiouracilo reportadas en este estudio se ajustan a las recomendaciones de la Asociación Americana de Endocrinología Clínica.

Abstract Introduction: the prevalence of disorders associated with thyrotoxicosis is not known in Colombia, nor pharmacoepidemiological studies are available on the prescription of antithyroid drugs. Objective: to determine the prescription patterns of antithyroid drugs and variables associated with their use in a population of Colombian patients. Methods: cross-sectional study, conducted between January 1 and March 30, 2015 on the prescription habits of antithyroid drugs in a population affiliated with the Colombian Health System. Sociodemographic, pharmacological and comedication variables were measured. A database on drug consumption was designed and student t-tests, X 2 and logistic regression models were used. Results: a total of 327 patients in treatment with antithyroid drugs were included. The mean age was 53.7 ± 18.1 years and 78.3% of patients corresponded to women. Methimazole was prescribed in 95.4% of patients, propylthiouracil in 4.6%. In 76.8% of patients, comedication was present in particular with antihypertensive agents (38.2%) and additionally with propranolol (34.3%). Conclusions: the prescription tendency of antithyroid drugs in Colombia is similar to that reported in different studies worldwide. The main antithyroid drug is methimazole, with a rate of use higher than that reported in North America and in European studies. The doses of methimazole and propylthiouracil reported in this study are in accordance with the recommendations of the American Association of Clinical Endocrinology.

Síndrome Carcinoide: Presentación de caso y revisión de la literatura / Carcinoid syndrome: case report and literature review

Se presenta el caso de una mujer de 63 años de edad, con cuadro clínico crónico de un año de evolución caracterizado por diarrea esteatorreica, asociado a episodios de dolor abdominal difuso, tipo cólico, “sensación de bochornos” y enrojecimiento en cara y tronco superior. El abordaje diagnóstico de la diarrea crónica es un reto para los médicos generales y especialistas, más aún, cuando se acompaña de manifestaciones inespecíficas como dolor abdominal y la presencia de “bochornos”. La coexistencia de varios de los anteriores síntomas, obliga a descartar diversas patologías que representan alta morbimortalidad para el paciente. El síndrome de intestino irritable, el feocromocitoma, el hipertiroidismo, el síndrome carcinoide, entre otras, son patologías a excluir en todo caso. El presente artículo pretende brindar el diagnóstico diferencial de las patologías que presentan dichos síntomas, buscando conducir al lector hasta el diagnóstico definitivo de la paciente.

A 63-year-old woman reported a chronic clinical evolution of one year characterized by steatorrhea, associated with episodes of diffuse abdominal pain, cramping and “hot flashes” also redness on the face and upper trunk . The diagnostic approach of chronic diarrhea is a challenge for physicians and specialists, especially, when accompanied by nonspecific manifestations such as abdominal pain and the presence of “hot flashes”. The coexistence of several of these symptoms must be ruled various pathologies that represent high morbidity and mortality for the patient. Irritable bowel syndrome, pheochromocytoma, hyperthyroidism, carcinoid syndrome, among others, are conditions to exclude in any case. This article aims to provide the differential diagnosis of the diseases that have these symptoms, seeking to lead the reader to the definitive diagnosis of the patient.
