Transient elastography to rule out esophageal varices and portal hypertensive gastropathy in HIV-infected individuals with liver cirrhosis.

Background/aims: It is recommended that patients with cirrhosis undergo endoscopic screening to rule out the presence of gastroesophageal varices: a noninvasive predictive method to identify cirrhotic patients with a very low risk of esophageal varices could potentially avoid unnecessary endoscopies.

Methods: We studied in 85 HIV-infected patients with cirrhosis the association between the absence of esophageal varices and portal hypertensive gastropathy, assessed by endoscopy, and liver stiffness measurement by transient elastography. We analyzed other parameters related to portal hypertension and hepatic function.

[Controversies and future of the approach to cardiovascular disease in HIV patients].

Cardiovascular diseases are an increasing problem in patients with HIV infection. The causes of the increased cardiovascular risk in HIV-infected patients are multifactorial. Currently, the question of which factor has the most weight in this equation - whether traditional risk factors, the virus per se or antiretroviral therapy - remains to be determined.

[Hypertension, HIV infection, and highly active antiretroviral therapy].

The decline in mortality resulting from the use of highly active antiretroviral therapy (HAART) has been accompanied by an increase in metabolic complications that produce accelerated atherosclerosis. Hypertension is one of the most important cardiovascular risk factors. Little is known about the impact of HAART on blood pressure, and it is uncertain whether chronic HIV infection or HAART have a role in the development of hypertension.
