ABSTRACT

Objetivo: Describir las situaciones relacionadas con la macrocitosis sin anemia en nuestrapoblación, entendida esta como un volumen corpuscular medio (VCM) mayor o igual a 97 fl ycifras de hemoglobina dentro de los límites normales poblacionales. Si descartadas las principalescausas recogidas en la literatura médica no existe justificación clara para esta macrocitosis,debe realizarse un test del aliento para valorar la posible asociación del aumento del VCM conla presencia de infección por Helicobacter pylori.Dise˜no: Transversal y descriptivo.Emplazamiento: Atención primaria.Mediciones principales: Las variables medidas fueron datos de filiación, antecedentes personalesy analíticos relacionados con la macrocitosis, consumo de tóxicos y fármacos. Todos estosdatos se recogieron de la historia clínica.Resultados: La prevalencia de macrocitosis sin anemia en la población de estudio fue de un7,12% (1.403/19.710). La principal causa que se encontró fue el hipotiroidismo en 37/234pacientes (15,8%), seguido del consumo elevado de alcohol en 34/234 pacientes (14,5%). Laasociación que se dio con mayor frecuencia fue la de consumo de alcohol y tabaco en 9/234pacientes (3,8%). En 87/234 pacientes (37,18%) no se halló causa conocida aparente de elevacióndel VCM. Se realizó el test del aliento a 37 pacientes y fue positivo en 23 pacientes(AU)


Conclusiones: La macrocitosis sin anemia es un hallazgo de alta prevalencia en nuestro medio.El hipotiroidismo es la causa que se encuentra en primer lugar, por delante del alcohol, causaprincipal en la literatura médica consultada, pero también es frecuente que exista más deuna causa por paciente que pueda justificar este hallazgo. Hoy en día, el H. pylori parecerelacionado con diversas enfermedades, digestivas o no, y puede ser causa de VCM elevado sinanemia. Sin embargo, en nuestro estudio no podemos concluir este hallazgo, pero podemosconfirmar la elevada prevalencia de H. pylori en nuestro medio(AU)


Objective: Observational study on a group of patients with macrocytosis without anaemia. Theprobable relationship of cause and effect between Helicobacter pylori and macrocytosis.Methods and material: An observational and cross-sectional study.Main measurements: The measured variables were: personal data, medical and analytical historyin relation to macrocytosis, alcohol and smoking habitss and drug use. This informationwas taken from the medical history of the patient.Results: The prevalence of macrocytosis without anaemia was 7.12%. The main cause found washyphothyroidism in 37/234 (15.8%) patients, followed by alcoholism in 34/234 (14.5%) patients.The most frequent association was alcohol and tobacco in 9/234 (3.8%) patients. It was notpossible to find a cause of the increased mean corpuscular volume (MCV) in 87/234 (37.18%)patients. Out of 37 tests conducted for Helicobacter pylori, 23 of them were positive.Discussion: Macrocytosis without anaemia has a high prevalence. Finding the most frequent causescould help in the early diagnosis and treatment. H. pylori currently appears to be associatedto different digestive tract and non-digestive tract diseases.It could be a cause of increasedMCV, but this study was unable demonstrate this(AU)

ABSTRACT

OBJECTIVE: Observational study on a group of patients with macrocytosis without anaemia. The probable relationship of cause and effect between Helicobacter pylori and macrocytosis. METHODS AND MATERIAL: An observational and cross-sectional study. MAIN MEASUREMENTS: The measured variables were: personal data, medical and analytical history in relation to macrocytosis, alcohol and smoking habits and drug use. This information was taken from the medical history of the patient. RESULTS: The prevalence of macrocytosis without anaemia was 7.12%. The main cause found was hypothyroidism in 37/234 (15.8%) patients, followed by alcoholism in 34/234 (14.5%) patients. The most frequent association was alcohol and tobacco in 9/234 (3.8%) patients. It was not possible to find a cause of the increased mean corpuscular volume (MCV) in 87/234 (37.18%) patients. Out of 37 tests conducted for Helicobacter pylori, 23 of them were positive. DISCUSSION: Macrocytosis without anaemia has a high prevalence. Finding the most frequent causes could help in the early diagnosis and treatment. H. pylori currently appears to be associated to different digestive tract and non-digestive tract diseases.It could be a cause of increased MCV, but this study was unable demonstrate this.
