Calves (n = 4) were given neomycin (2.25 or 4.5 mg/kg) twice daily IM and were compared with 2 calves given penicillin IM. The 2 hallmarks of aminoglycoside toxicosis, nephrotoxicosis and ototoxicosis, were seen with both dosages of parenterally administered neomycin. Nephrotoxicosis was confirmed by abnormal findings in urinalysis (granular casts, proteinuria, low specific gravity), renal biopsy results (tubular degeneration and necrosis), and increased 24-hour amounts of urinary enzymes (alanine aminopeptidase and gamma-glutamyltranspeptidase). Azotemia, decreased creatinine clearance, polyuria, and polydipsia also were documented in calves given neomycin. Clinically, deafness was suspected in 2 calves and was documented by electrical auditory-evoked response tests. Abnormalities in partial thromboplastin times and renal residues of neomycin were seen in all 4 calves that were given neomycin, but not in calves that were given penicillin.

Alpha 1-Antitrypsin deficiency predisposes to pulmonary emphysema, liver cirrhosis and hepatocellular carcinoma. Anecdotal evidence and a large autopsy study suggest that severe lung and liver disease rarely coexist in the same subject, but this has not been studied in patients. Therefore we investigated 27 patients with severe alpha 1-deficiency (Pi ZZ) and pulmonary emphysema for signs of liver disease and impaired hepatic function. A subgroup of 7 patients underwent quantitative liver function tests. On physical examination or ultrasonography, cirrhosis or tumor was not suspected in any patient. Conventional liver function tests were completely normal in 17 patients. Elevated serum activities of gamma-glutamyltranspeptidase and/or aminotransferases were seen in 10 patients. In some, the elevation was only marginal and in none more than twice normal. The serum bilirubin concentration and activity of alkaline phosphatase were increased in 1 patient. Serum protein, albumin, fibrinogen, antithrombin III, alpha 1-fetoprotein concentrations, serum activities of cholinesterase and glutamate dehydrogenase, activated partial thromboplastin time and prothrombin time were normal in all patients. The indocyanine green half-life was abnormal only in 1 of 6 patients, suggesting that hepatic blood flow was not impaired in the study group. However, the lidocaine half-life and galactose elimination capacity, parameters of hepatic metabolization, were impaired in 4 and 6 of 7 patients, respectively. We conclude that liver disease or impaired liver function is not a clinically relevant problem in most patients with pulmonary emphysema due to alpha 1-antitrypsin deficiency. But results of quantitative liver function tests, although performed in only a small group of patients, suggest that hepatic metabolization might be impaired even in those patients who present with pulmonary disease.
