Rat hepatitis E virus () in people living with HIV.

Rat hepatitis E virus (ratHEV; species ) is considered a newly emerging cause of acute hepatitis of zoonotic origin. ratHEV infection of people living with HIV (PLWH) might portend a worse, as with hepatitis E virus (HEV; species ), and consequently this group may constitute a high-risk population. We aimed to evaluate the prevalence of ratHEV by measuring viral RNA and specific IgG antibodies in a large Spanish cohort of PLWH.

Hepatocellular carcinoma after sustained virological response with interferon-free regimens in HIV/hepatitis C virus-coinfected patients.

Objective: To assess the possible association between the use of direct antiviral agents (DAA) and the risk of hepatocellular carcinoma (HCC) in HIV/hepatitis C virus (HCV)-coinfected patients.

Methods: The GEHEP-002 cohort recruits HCC cases in HIV-infected patients from 32 centers from Spain. Three analyses were performed: the proportion of HCC cases after sustained virological response (SVR) and the evolution of this proportion over time, the frequency of HCC after SVR in HIV/HCV-coinfected patients with cirrhosis, and the probability of HCC recurrence after curative therapies among those undergoing HCV therapy.

Bone alterations in hepatitis C virus infected patients.

Background And Aims: Most studies have shown that patients with chronic hepatitis C virus (HCV) infection are affected by osteoporosis. However, liver function impairment and deranged nutrition may both play a role in the bone alterations observed. In some works no osteoporosis was found, and some cases of osteosclerosis have been reported.

Similar inflammatory response in alcoholic and non-alcoholic sepsis patients.

Unlabelled: It is well known that alcoholics are prone to severe infections and that the immune system is impaired by chronic ethanol abuse. The aim of this study is to compare serum inflammatory mediators in response to sepsis in chronic alcoholic with sepsis, non-alcoholics with sepsis and non-infected alcoholics.

Method: We included 25 alcoholics with sepsis, 34 non-alcoholics with sepsis, 34 non-infected alcoholics admitted for programmed withdrawal, and 27 healthy control subjects.

Prognostic value of inflammatory markers (notably cytokines and procalcitonin), nutritional assessment, and organ function in patients with sepsis.

Objective: Procalcitonin is useful for the diagnosis of sepsis, but its prognostic value regarding mortality is unclear. Our objective was to determine the prognostic value of procalcitonin determined at the onset of sepsis, and to compare it with other markers of inflammatory response, malnutrition and organ dysfunction data.

Methods: We studied 253 hospitalized patients (146 men, 107 women) with a median age of 65 years.

Factors involved in the paradox of reverse epidemiology.

Background & Aims: The hypothesis of reverse epidemiology holds that some cardiovascular risk factors, such as obesity, hypercholesterolemia and hypertension, in the elderly or in some chronic diseases are not harmful but permit better survival. However, this phenomenon is controversial and the underlying reasons are poorly understood.

Objective: To search for factors simultaneously linked to reverse epidemiology and to short or long term survival.

Association of Harris lines and shorter stature with ethanol consumption during growth.

Ethanol consumption may impair bone growth. Transverse radiopaque lines (Harris lines) have been interpreted as manifestations of bone growth arrest due to nutritional stress. It is possible that ethanol consumption during growth leads to Harris lines formation and to a shorter stature.

Prognosis of community acquired pneumonia (CAP): value of triggering receptor expressed on myeloid cells-1 (TREM-1) and other mediators of the inflammatory response.

Unlabelled: TREM-1 is an activating receptor expressed on the surface of neutrophils and mature monocytes when stimulated by bacteria or fungi, leading to amplification of the inflammatory response. Our objective is to analyze the prognostic value of serum sTREM-1 levels and other mediators of the inflammatory response, in patients hospitalized for CAP, and to compare its prognostic value with those of advanced age, pneumonia severity scores, Charlson index, nutritional status and severity of sepsis.

Methods: We included 226 patients with CAP, 145 males and 81 females, median age of 74 years.

Clinical significance of homocysteine in elderly hospitalized patients.

Serum homocysteine levels, which increase with age, are now recognized as a vascular risk factor and are related to the development of heart failure and dementia in the elderly. However, relatively low serum homocysteine levels have also been reported to be an adverse prognostic factor in dialysis patients. The objective of the study was to analyze the prevalence, clinical significance, and prognostic value of serum homocysteine levels in patients older than 65 years, admitted to a general internal medicine hospitalization unit.

Rib fractures in chronic alcoholic men: Relationship with feeding habits, social problems, malnutrition, bone alterations, and liver dysfunction.

Rib fractures are common in alcoholics. This high prevalence might be due to ethanol-associated malnutrition, bone disease, liver dysfunction, or the peculiar lifestyle of the alcoholic with frequent trauma and altercations. In this study we try to discern the role of these factors on rib fracture (assessed on a plain thoracic X-ray film) in 81 consecutive alcoholic patients, 25 of them cirrhotics.
