The present study was aimed at determining the prevalence of H. pylori infection among cirrhotic patients and to explore its relationship to demography, etiology of cirrhosis, and liver function.The prevalence of Helicobacter pylori in patients with alcoholic and nonalcoholic cirrhosis is uncertain. The present study was aimed at determining the prevalence of H. pylori infection among cirrhotic patients and to explore its relationship to demography, etiology of cirrhosis, and liver function.Materials and Methods.Thirty-three cirrhotic patients were included. H. pylori infection was determined by the 14C urea breath test (n = 30) and endoscopy with antral biopsy (n = 4). Etiology of cirrhosis was classified as alcoholic or nonalcoholic. The rate of H. pylori infection was related to age, gender, etiology, Child-Pugh grading, portal hypertension, and portal-systemic encephalopathy (PSE). None of the patients received antibiotics for at least the last 3 months.Thirty-three cirrhotic patients were included.

The rate of H. pylori infection was related to age, gender, etiology, Child-Pugh grading, portal hypertension, and portal-systemic encephalopathy (PSE). None of the patients received antibiotics for at least the last 3 months.Results.Twelve alcoholic and 21 nonalcoholic cirrhotics, with a median age of 57 years and a male:female ratio of 1 : 1.4 were studied. Overall H. pylori prevalence was 45.5%. This prevalence varied from 47.1% to 43.8% in those younger and older than the median age, and from 35.7% to 52.6% in men and women, respectively. Fifty percent of alcoholic and 42.9% of nonalcoholic cirrhotics were H. pylori–positive. According to Child-Pugh grading, 69% of grade A, 40% of grade B, and 0% of grade C were infected ( p = .03). Among patients with PSE, 25% were H. pylori–positive compared to 52% of those without PSE ( p = .24).Twelve alcoholic and 21 nonalcoholic cirrhotics, with a median age of 57 years and a male:female ratio of 1 : 1.4 were studied.

Among patients with PSE, 25% were H. pylori–positive compared to 52% of those without PSE ( p = .24).Conclusions.The prevalence of H. pylori infection in cirrhotics is 45.5%. Prevalence was unrelated to age, gender, and etiology of cirrhosis. An inverse relation to the Child-Pugh grading and a tendency to a lower prevalence in PSE was found.The prevalence of H. pylori infection in cirrhotics is 45.5%.

Existen numerosas descripciones y representaciones de bultos sagrados en fuentes coloniales y en documentos pictográficos prehispánicos, siendo la región de la Mixteca la que mayor cantidad de ejemplos presenta. Este aspecto de la religiosidad mixteca manifestada a través de los bultos se puede encontrar en rituales de fundación, en ceremonias de entronización de los gobernantes, en las fiestas periódicas que involucraban a toda la comunidad, pero también en cultos particulares o privados que realizaba el dueño de algún bulto. Al parecer, el culto a los fardos sagrados estaba tan extendido en la Mixteca que quizá constituyó la principal manifestación religiosa de esta región en la época prehispánica.
