Long interval between HCV infection and development of hepatocellular carcinoma

Abstract: A high prevalence of HCV infection has been reported in patients with hepatocellular carcinoma. The progression from acute transfusion-associated hepatitis to hepatic cirrhosis and hepatocellular carcinoma has been suggested in several studies to be very long. We have investigated the prevalence of anti-HCV and the interval between HCV infection and hepatocellular carcinoma among 191 consecutive patients with cirrhosis and liver-cell carcinoma. Serum samples from 191 patients with cirrhosis and hepatocellular carcinoma, consecutively diagnosed in our hospital between 1988 and 1993, were tested for serological markers of HBV and HCV infection. One hundred and forty-eight patients (77.5%; 95% confidence interval (c.i): 76% to 80%) were anti-HCV positive by 2nd generation enzyme immunoassay (confirmed by 2nd generation recombinant immunoblot assay) and 152 patients (79.5%; 95% c.i: 76% to 80%) were anti-HCV positive by 3rd generation enzyme immunoassay, while only 14 (7.4%; 95% c.i: 5% to 10%) were HBsAg positive. Of the 29 anti-HCV positive patients with previous transfusion, the interval between the date of blood transfusion and the diagnosis of hepatic cirrhosis was 24±12.5 years and that of hepatocellular carcinoma was 26.8±12.4 years. These results confirm the high prevalence of HCV infection in patients with hepatocellular carcinoma and the slow sequential progression from HCV infection through cirrhosis and hepatocellular carcinoma.

Salivary Secretory Disorders,Inducing Drugs,and Clinical Management

Background: Salivary secretory disorders can be the result of a wide range of factors. Their prevalence and negative effects on the patient''s quality of life oblige the clinician to confront the issue.Aim: To review the salivary secretory disorders, inducing drugs and their clinical management.Methods: In this article, a literature search of these dysfunctions was conducted with the assistance of a research librarian in the MEDLINE/PubMed Database.Results: Xerostomia, or dry mouth syndrome, can be caused by medication, systemic diseases such as Sjögren''s Syndrome, glandular pathologies, and radiotherapy of the head and neck. Treatment of dry mouth is aimed at both minimizing its symptoms and preventing oral complications with the employment of sialogogues and topical acting substances. Sialorrhea and drooling, are mainly due to medication or neurological systemic disease. There are various therapeutic, pharmacologic, and surgical alternatives for its management. The pharmacology of most of the substances employed for the treatment of salivary disorders is well-known. Nevertheless, in some cases a significant improvement in salivary function has not been observed after their administration.Conclusion: At present, there are numerous frequently prescribed drugs whose unwanted effects include some kind of salivary disorder. In addition, the differing pathologic mechanisms, and the great variety of existing treatments hinder the clinical management of these patients.The authors have designed an algorithm to facilitate the decision making process when physicians, oral surgeons, or dentists face these salivary dysfunctions.     

Transient elastography in DAA era. Relation between post‐SVR LSM and histology

The natural history of HCV chronic infection has drastically changed after direct‐acting antiviral treatment. Due to the high sustained virological response (SVR) achieved, noninvasive estimation of liver fibrosis regression has become a major key point. The present study tries to evaluate the relation between liver histology and liver stiffness measurement (LSM) by transient elastography (TE) after SVR.     

Documento de consenso sobre el fenotipo mixto EPOC-asma en la EPOC

Introduction

Although asthma and COPD are different pathologies, many patients share characteristics from both entities. These cases can have different evolutions and responses to treatment. Nevertheless, the evidence available is limited, and it is necessary to evaluate whether they represent a differential phenotype and provide recommendations about diagnosis and treatment, in addition to identifying possible gaps in our understanding of asthma and COPD.

Methods

A nation-wide consensus of experts in COPD in two stages: 1) during an initial meeting, the topics to be dealt with were established and a first draft of statements was elaborated with a structured «brainstorming» method; 2) consensus was reached with two rounds of e-mails, using a Likert-type scale.

Results

Consensus was reached about the existence of a differential clinical phenotype known as «Overlap Phenotype COPD-Asthma», whose diagnosis is made when 2 major criteria and 2 minor criteria are met. The major criteria include very positive bronchodilator test (increase in FEV₁ ≥ 15% and ≥ 400 ml), eosinophilia in sputum and personal history of asthma. Minor criteria include high total IgE, personal history of atopy and positive bronchodilator test (increase in FEV₁ ≥ 12% and ≥ 200 ml) on two or more occasions. The early use of individually-adjusted inhaled corticosteroids is recommended, and caution must be taken with their abrupt withdrawal. Meanwhile, in severe cases the use of triple therapy should be evaluated. Finally, there is an obvious lack of specific studies about the natural history and the treatment of these patients.

Conclusions

It is necessary to expand our knowledge about this phenotype in order to establish adequate guidelines and recommendations for its diagnosis and treatment.     

Metabolic syndrome in Spain: prevalence and coronary risk associated with harmonized definition and WHO proposal. DARIOS study

Introduction and objectives

To update the prevalence of metabolic syndrome and associated coronary risk in Spain, using the harmonized definition and the new World Health Organization proposal (metabolic premorbid syndrome), which excludes diabetes mellitus and cardiovascular disease.

Methods

Individual data pooled analysis study of 24 670 individuals from 10 autonomous communities aged 35 to 74 years. Coronary risk was estimated using the REGICOR function.

Results

Prevalence of metabolic syndrome was 31% (women 29% [95% confidence interval, 25%-33%], men 32% [95% confidence interval, 29%-35%]). High blood glucose (P=.019) and triglycerides (P<.001) were more frequent in men with metabolic syndrome, but abdominal obesity (P<.001) and low high-density lipoprotein cholesterol (P=.001) predominated in women. Individuals with metabolic syndrome showed moderate coronary risk (8% men, 5% women), although values were higher (P<.001) than in the population without the syndrome (4% men, 2% women). Women and men with metabolic syndrome had 2.5 and 2 times higher levels of coronary risk, respectively (P<.001). Prevalence of metabolic premorbid syndrome was 24% and the increase in coronary risk was also proportionately larger in women than in men (2 vs 1.5, respectively; P<.001).

Conclusions

Prevalence of metabolic syndrome is 31%; metabolic premorbid syndrome lowers this prevalence to 24% and delimits the population for primary prevention. The increase in coronary risk is proportionally larger in women, in both metabolic syndrome and metabolic premorbid syndrome.Full English text available from:www.revespcardiol.org
