Antibodies to hepatitis B virus and hepatitis C virus in alcoholic hepatitis and cirrhosis: their prevalence and clinical relevance. The VA Cooperative Study Group (No. 119)

Patients with overt alcoholic liver disease who had participated in a multicenter therapeutic trial and subgroups of controls (i.e., alcoholic patients without liver disease and patients with neither alcoholism nor liver disease) were tested for hepatitis B virus and hepatitis C virus antibodies to determine the prevalence of these antibodies to determine the prevalence of these antibodies and any clinical association in the progression and outcome of alcoholic liver disease. Antibodies to hepatitis B (anti-HBs and/or anti-HBc) were found in 29.2% of patients with alcoholic liver disease, in 26.1% of hospitalized alcoholic patients without liver disease and in 24.2% of hospitalized nonalcoholic patients without liver disease; frequencies were not significantly different from one another. HBsAg was not evaluated because HBsAg+ patients had been excluded from the original trial. The presence of these antibody markers correlated with ethnic origin of and immunoglobulin levels in the patients. In contrast, antibody to hepatitis C, as detected by enzyme immunoassay, was positive in 27.1%, 4.8% and 3.0% of the three groups, respectively, the first differing significantly from the other two. Antibody to hepatitis C virus positivity correlated significantly with clinical severity of the disease and with the presence of histological features that imply chronic viral infection (periportal inflammation, cirrhosis), despite the fact that the supplementary assay for antibody to hepatitis C virus, using recombinant immunoblot assay, reduced the positive rate by 79%.(ABSTRACT TRUNCATED AT 250 WORDS)

Alpha-fetoprotein alterations in alcoholics with liver disease. V.A. Cooperative Study Groups.

Sera on 409 male alcoholics with liver injury were assayed for alpha-fetoprotein (AFP) as part of a VA co-operative study on the natural history and therapy of alcoholic liver disease. In 78% of the patients values below normal were observed and 42% had undetectable levels. Clinically the lowest AFP concentrations were observed in the more severely ill patients with the poorest 1 year survival. Furthermore, improvement in AFP was associated with improved survival. Correlation analysis showed a relationship of AFP to (1) visceral protein concentrations (i.e. albumin, transferrin, retinal binding protein); (2) variables related to hepatic fibrogenesis (i.e. Ito cell activity, quantitative estimates of fibrosis and Kupffer cell abnormalities); and (3) changes in immunoglobulin levels particularly IgG. These findings suggest that AFP is a good index of disease prognosis.

Polymicrobial bacteremia.

Of 26,961 blood cultures taken during an 18-month period at the Cincinnati General Hospital, 1,715 (6%) were positive. Ninety-four patients had blood cultures containing more than one organism. Although aerobic and anaerobic streptococci were the most frequently isolated bacteria, a variety of microorganisms, including Staphylococcus aureus and the Klebsiella-Enterobacter-Serratia group, was isolated in different combinations depending on the underlying disease. Neurological illness, malignant neoplasms, burns, and decubitus ulcers were among the most common underlying conditions found. The overall mortality was 54%, but only 58% of these deaths were specifically related to an episode of polymicrobial bacteremia. Patient survival was significantly related to appropriate antimicrobial therapy.

Aspergillus flavipes group osteomyelitis.

Lumbar vertebral osteomyelitis caused by Aspergillus Flavipes group organisms developed in a nonchronically immunosuppressed patient. Diagnosis was confirmed morphologically and culturally from both closed needle biopsy of the vertebrae and subsequent lumbar laminectomy. The patient was treated with 3 g of amphotericin B with apparent eradication of the organism.

Carbenicillin nephrotoxicity.

A patient with biopsy-proven interstitial nephritis associated with nafcillin and dicloxacillin therapy developed fever, hematuria, pyuria, and renal insufficiency after the administration of carbenicilin five months later. Cephalosporin therapy was given to this patient without signs of renal toxicity. This is the first reported case of probable carbenicillin-induced interstitial nephritis and serves to emphasize the danger of giving any penicillin analogue to patients with a history of pencillin-induced interstitial nephritis.

Amphotericin B and 5-fluorocytosine: in vitro effects on lymphocyte function.

The effects of amphotericin B, 5-fluorocytosine, and the combination of both drugs on lymphocyte function in vitro were investigated. Amphotericin B, alone or in combination with 5-fluorocytosine, significantly suppressed both spontaneous lymphocyte transformation and the response of lymphocytes to stimulation with streptokinase-streptodornase. 5-Fluorocytosine had no effect on spontaneous or antigen-induced transformation. Lymphocyte responses to the mitogens phytohemagglutinin and concanavalin A were not changed by exposure to amphotericin B, 5-fluorocytosine, or the combination of both drugs. T-lymphocyte receptors for sheep erythrocytes and B-lymphocyte surface immunoglobulin and receptors for complement were not changed by treatment with amphotericin B or 5-fluorocytosine.

Evaluation of influenza A/New Jersey/76 split-product virus vaccine in a summer camp.

An evaluation of two doses of split-product A/New Jersey/76 virus vaccines was conducted at a boys' summer camp. Two doses of either 200 chick cell-agglutinating (CCA) or 400 CCA units of vaccine were administered four weeks apart. There were no significant side effects. Of 60 subjects, 59 developed a significant titer of serum antibody after two doses. There was no correlation between titer of antibody and total dose of vaccine. Younger subjects developed a higher titer than older subjects. A single dose of vaccine was insufficient to achieve a protective level of antibody.

Case report: invasive pulmonary aspergillosis in a nonimmunosuppressed patient.

A patient with no known underlying immunosuppressive disorder who developed invasive pulmonary aspergillosis is described. A review of the English literature revealed ten other presumably nonimmunosuppressed patients with invasive aspergillosis. All had evidence of necrotizing pneumonitis with frequent cavity formation. Nine of the 11 patients died without the diagnosis of aspergillosis having been entertained. Invasive pulmonary aspergillosis does occur in the nonimmunosuppressed host and should be considered when an etiologic agent is not readily identified in a patient with rapidly progressive diffuse necrotizing pneumonitis.
