Epidemiology of Metastatic Hepatocellular Carcinoma,A Nationwide Perspective

Background

Hepatocellular carcinoma (HCC) is the most common primary tumor of the liver.

Aims

The aim of this study was to describe the prevalence, trends, and predictors of metastatic HCC on a national scale.

Methods

We used two nationwide datasets for our study: the University Health Consortium (UHC) and the Nationwide Inpatient Sample (NIS) databases. We included adults with a primary diagnosis of HCC from 2000 to 2011. We collected information regarding demographics, insurance, HCC risk factors, liver decompensation, and the sites and frequencies of metastases. Multivariable regression analysis was used to examine predictors of metastatic HCC. Trend analysis was performed to examine the change in metastatic HCC prevalence over time.

Results

We included 25,671 and 26,054 HCC patients from UHC and NIS, respectively. Prevalence of metastatic HCC was 18 % with lung being the most frequent site (31 %). Compared with Caucasian, African American ethnicity was an independent predictor of metastasis in both the NIS [OR 1.13 (1.02–1.25)] and UHC [OR 1.4 (1.3–1.6)] databases. Lack of long-term insurance was associated with significantly higher prevalence of metastasis in both the NIS [OR 1.6 (1.4–1.9)] and UHC [OR 1.9 (1.6–2.2)] databases. There has been an increased prevalence of metastatic HCC over the last decade with an annual percentage change of +1.25 and +1.60 % (p = 0.03 and p = 0.08) for the NIS and UHC databases, respectively.

Conclusions

Metastasis is not rare among HCC patients and is rising in prevalence over the last decade. Lungs were the most common metastatic site. Ethnicity and insurance status are independent predictors of metastasis.     

Endocarditis infecciosa en 2 hospitales universitarios españoles que difieren en su localización y en la presencia de servicio quirúrgico

Objectives

To assess possible differences in clinical presentation, microbiology, morbidity and mortality of infective endocarditis between two Spanish hospitals, one on the mainland that has cardiac surgery and one in the Canary Islands without this service.

Method

A total of 229 patients consecutively diagnosed of endocarditis between 2005 and 2012, including pediatric population, were studied in the Reina Sofía Hospital (Córdoba, n = 119) and Nuestra Señora de Candelaria Hospital (Tenerife, n = 110). We compared the clinical, microbiological and echocardiographic data and analyzed mortality differences by binary logistic regression analysis.

Results

There were no differences in underlying heart disease, proportion of surgery, or the microbiological profile. The proportion of infections attributable to catheter was higher in the Canary Islands hospital (13.6% vs 3.4%). Mortality was also higher (31.8% vs 18.5%, P = .020), although this difference was no longer significant in the multivariate analysis (OR = 1.85; 95% CI, 0.70-4.87; P = .213). Age (OR = 1.04/year; 95% CI, 1.01-1.07; P = .006), cardiac complications (OR = 5.05; 95% CI, 1.78-14.34; P = .002), persistent sepsis (OR = 4.89; 95% CI, 2.09-11.46; P < .001), and emergent surgery (OR = 4.43, 95% CI, 1.75-11.19; P = .002) were independent predictors of death. Time to surgery, length of stay in the hospital without a surgical service (20 [13-30.5] vs 13 [6-25] days; P = .019) was not associated with outcome.

Conclusions

There are differences in the presentation of endocarditis between two distant hospitals in Spain. The different hospital mortality can not be directly related to the presence of a surgery service.     

Evaluación inicial del programa de prevención de la transmisión materno-infantil de la infección por el virus de la inmunodeficiencia humana en Guinea Ecuatorial

Background

The prevalence of human immunodeficiency virus (HIV)-infected pregnant women in Equatorial Guinea (EG) has been reported as 7.3%. In 2008 an updated version of the PMTCT protocol was accepted according to the current WHO guidelines. The aim of this study was to describe the characteristics and outcome of children exposed to HIV after the introduction of the protocol.

Methods

A retrospective review was conducted on the clinical characteristics of the infants born to HIV-infected mothers in the Hospital Regional de Bata and Primary Health Care Centre Maria Rafols in Bata (EG) between June 2008 and November 2011. The diagnosis of HIV infection in children was based on rapid serology tests.

Results

A total of 103 children were included, of which 47 were males. Fifty three patients (51%) completed the follow-up (51%). Fourteen children (26%) were diagnosed with HIV infection (11 presumptive diagnosis, 3 due to persistence of antibodies at 18 months). Six children (12%) died before a definitive diagnosis. Just over than half (52%) of mothers received antiretroviral therapy (ART) during pregnancy. The transmission rate in children whose mothers received ART was 16% (3/19), compared with 43% (10/23) in children whose mothers did not receive it. Only one child was infected (8%) when the mother received ART, and child received postnatal prophylaxis.

Conclusions

The PMTCT protocol compliance was still very low. Antiretroviral therapy in pregnant women decreased the rate of vertical transmission, but the rate still remains very high. Many children were lost to follow-up. Strategies to prevent loss to follow-up and methods for earlier virological diagnostic are needed.     

Documento de consenso: Recomendaciones para el manejo de la enfermedad ósea metabólica en pacientes con virus de la inmunodeficiencia humana

Objective

To provide practical recommendations for the evaluation and treatment of metabolic bone disease in human immunodeficiency virus (HIV) patients.

Participants

Members of scientific societies related to bone metabolism and HIV: Grupo de Estudio de Sida (GeSIDA), Sociedad Española de Endocrinología y Nutrición (SEEN), Sociedad Española de Investigación Ósea y del Metabolismo Mineral (SEIOMM), and Sociedad Española de Fractura Osteoporótica (SEFRAOS).

Methods

A systematic search was carried out in PubMed, and papers in English and Spanish with a publication date before 28 May 2013 were included. Recommendations were formulated according to GRADE system (Grading of Recommendations, Assessment, Development, and Evaluation) setting both their strength and the quality of supporting evidence. Working groups were established for each major part, and the final resulting document was later discussed in a face-to-face meeting. All the authors reviewed the final written document and agreed with its content.

Conclusions

The document provides evidence-based practical recommendations on the detection and treatment of bone disease in HIV-infected patients.     

Enfermedades inflamatorias mediadas por inmunidad en pacientes con enfermedad inflamatoria intestinal. Datos basales del estudio Aquiles

Objective

To determine the prevalence of immune-mediated inflammatory diseases (IMID) in a cohort of patients with inflammatory bowel disease (IBD) enrolled in hospital gastroenterology outpatients units for the AQUILES study, a prospective 2-year follow-up study.

Material and methods

We included patients ≥ 18 years old with a prior or new diagnosis of IBD (Crohn disease [CD], ulcerative colitis [UC] or indeterminate colitis). Diagnoses were collected in a cross-sectional manner from the clinical records at enrollment of a new patient in the study.

Results

We included 526 patients (mean age 40.2 years; 47.3% men, 52.7% women), 300 with CD (57.0%), 218 with UC (41.4%) and 8 with indeterminate colitis. Other types of IMID were present in 71 patients (prevalence: 13.5%, 95% CI: 10.8-16.7): 47 were spondyloarthropathies (prevalence: 8.9%); 18 psoriasis (3.4%); 5 pyoderma gangrenosum (1.0%), and 11 uveitis (2.1%). The prevalence of IMID was higher in patients with CD than in those with UC (17.0% [95% CI: 13.2-21.7] vs 9.2% [95% CI: 6.0-13.8], p = 0.011). In the multivariate analysis, the variables associated with the presence of IMID were diagnosis of CD (OR = 1.8 [95% CI: 1.1-3.2]) and duration of IBD ≥ 4 years (OR = 2.1 [95% CI: 1.1-4.1] in those with disease duration 4-8 years, and OR = 2.1 [95% CI: 1.2-3.9] in those with ≥ 8 years vs. < 4 years).

Conclusions

In the cohort of patients with IBD in the AQUILES study, 13.5% had another IMID, with a higher prevalence in patients with CD and > 4 years since disease onset.
