Hepatitis C crónica: aspectos clínicos, serológicos y de tratamiento en dos centros de atención en Bogotá, Colombia.

Introduction: Hepatitis C affects about 170 million people worldwide. The World Health Organization (WHO) has estimated global prevalence at 2%. Overall, about 40% of patients respond to dual therapy treatment for genotype. In Colombia data available for confirm a similar pattern and for describing the clinical characteristics of patients with this infection are scarce. Methods: Medical records of patients in the Hepatology outpatient service at the Clínica Universitaria Colombia who had been diagnosed with chronic hepatitis C by one of the authors between January 1, 2010 and May 30, 2013 were retrospectively reviewed for clinical characteristics, serological characteristics and treatment responses. Results: The medical records of 163 patients were evaluated: 62% were female, 38% were male, and their mean age was 58.2 years. The main risk factor for acquiring hepatitis C was a history of transfusions before 1992. This factor was present in 62% of the patients. The decision to start treatment was made for 77 patients (47.2%), but 86 patients (52.8%) did not start treatment. Reasons included advanced age and advanced cirrhosis which together accounted for more than 50% of these patients. Other reasons for not starting treatment were minimal disease (4.7%), minimal sign of disease plus advanced age (10.5%), spontaneous healing (14%), low probability of response (3.3%) and others (14%). Of the 62 patients for whom information about previous or recent treatments was available, 30.6% had sustained virological responses (SVR), 29.0% were classified as relapsers, 8.1% as partial responders, 19.4% had no response, and 12.9% discontinued treatment because of intolerance. Conclusions: The most frequent antecedent of HCV in the group of patients studied a history of transfusions associated with gynecological surgery before 1992. About half of the patients were diagnosed late. Hepatitis was more likely to have been treated in these patients than in patients in other studies, but the SVR rate was similar to those found in other series. This study opens doors to the realization of other studies to more broadly define the prevalence, risk factors and treatment response variables of this entity in our country. [ABSTRACT FROM AUTHOR]
