Real-life experience of hepatitis C treatment in a Spanish prison.

OBJECTIVE: Hepatitis C virus (HCV) infection is a major public health problem that causes multiple comorbidities. People in prisons who inject intravenous drugs are at increased risk of HCV infection, and HCV infection is 15-fold more prevalent among prisoners compared with the community. The objective of this study was to analyse the clinical and epidemiological characteristics of residents of a Spanish prison with HCV infection who received antiviral treatment. METHODS: An observational, descriptive and retrospective study was performed. All patients with HCV infection diagnosed or followed up in an Infectious Diseases attached to a penitentiary were included in this study. RESULTS: Of 81 patients analysed, sixty-nine (83.1%) patients were male. The mean age was 50.1 (SD8.8) years, and 70% of the inmates had a history of injection drug use. Coinfection with HIV was detected in 30%. In up to 25% of the sample, there were data on chronic liver disease in the degree of liver cirrhosis. The diagnosis of HCV infection had been made more than 15 years earlier in 28% of those studied. Decompensations from liver disease, hepatocellular carcinoma, or hospital admissions were exceptional. Most of the inmates with HCV accepted treatment, and approximately 94% of the patients who completed treatment achieved a sustained virological response without interactions or complications of interest. CONCLUSIONS: The availability of direct-acting antivirals and their exceptional side effects constitute an opportunity to reduce the burden of HCV infection in Spain, particularly in these high-risk populations.

Urinary tract infection caused by Enterococcus spp.: Risk factors and mortality. An observational study.

BACKGROUND AND OBJECTIVE: Urinary tract infections (UTIs) are frequently caused by Enterococcus spp. This work aims to define the risk factors associated with UTIs caused by Enterococci and to determine its overall mortality and predictive risk factors. MATERIALS AND METHODS: A retrospective study was conducted on bacteremic UTIs caused by Enterococcus spp. among inpatients. We compared 106 inpatients with bacteremic UTIs caused by Enterococcus spp. vs. a random sample of 100 inpatients with bacteremic UTIs caused by other enterobacteria. RESULTS: A total of 106 inpatients with UTIs caused by Enterococcus spp. were analyzed, 51 of whom had concomitant positive blood cultures. Distribution by species was 83% E. faecalis and 17% E. faecium. The mean Charlson Comorbidity Index score was 5.9±2.9. Upon comparing bacteremic UTIs caused by Enterococcus spp. vs. bacteremic UTIs caused by others enterobacteria, we found the following independent predictors of bacteremic UTI by Enterococcus: male sex, obstructive uropathy, nosocomial infection, cancers of the urinary system, and previous antimicrobial treatment. Overall, inpatient mortality was 16.5% and was associated with a higher Sequential Organ Failure Assessment (SOFA) score (>4); severe comorbidities such as immunosuppression, malignant hemopathy, and nephrostomy; and Enterococcus faecium species and its pattern of resistance to ampicillin or vancomycin (p<0.05). Appropriate empiric antibiotic therapy was not associated with a better prognosis (p>0.05). CONCLUSIONS: Enterococcus spp. is a frequent cause of complicated UTI in patients with risk factors. High mortality secondary to a severe clinical condition and high comorbidity may be sufficient for justifying the implementation of empiric treatment of at-risk patients.
