Hepatic hydrothorax in the absence of ascites: respiratory failure in a cirrhotic patient.

The frequency of hepatic hydrothorax in cirrhotic patients is reported to be approximately 5%. The pleural effusion is predominantly right-sided (85% of cases) but may be bilateral. Although most often accompanied by significant ascites, it can occur in its absence.

Beta 2-microglobulin and immunoglobulins are more useful markers of disease progression in HIV than neopterin and adenosine deaminase.

Reference change values of six biochemical quantities (beta 2-microglobulin, neopterin, adenosine deaminase and immunoglobulins IgA, IgG and IgM) have been established in asymptomatic human immunodeficiency virus (HIV)-infected patients following the method described by Harris and Yasaka in 1983. Patients included in the evaluation were classified as A1, A2 or A3 according to the classification of the Centers for Disease Control (CDC) (January 1993). All patients were followed-up quarterly, with a minimum of four samples each available for statistical analysis.

The predictive value of several markers in the progression to acquired immunodeficiency syndrome.

Serum beta 2-microglobulin, neopterin, immunoglobulins A, G and M, adenosine deaminase and CD4+ lymphocyte count were evaluated as predictors of progression of HIV-1 infection to AIDS. A population of HIV-1 seropositive, initially asymptomatic men (n = 213) and women (n = 101) was followed up quarterly. We estimated the AIDS-free time using the actuarial method (median survival time 47.
