In 50 patients with mitral stenosis in the stage of maximal clinical improvement a correlation between the functional state of liver and the morphological changes was estblished. For this purpose the serum total bilirubin concentration was determined together with the serum total protein, albumin and globulin levels, serum alanine aminotransferase, aspartate aminotransferase, cholinesterase, leucylaminopeptidase, and alkaline phosphatase activities. The bromsulphalein test, provoked hypoprothrombinemia test, and histological examination of liver biopsy specimens were made. It was found that with increasing liver morphological lesions there is a gradual but not parallel impairment of function. The most sensitive index of hepatic functional disturbances was the test of provoked hypoprothrombinemia according to Kirchmayer and Bromowiczowa. For full assessment of the degree to which the changes in the congested liver have advanced it is necessary to perform liver function tests in combination with histological examination of the organ.

A patient who developed chronic salicylism associated with salicylate therapy for treatment of juvenile rheumatoid arthritis is described, and the clinical presentation and treatment of chronic salicylism are reviewed. A 5 1/2-year-old boy was receiving aspirin 150/mg/kg/day for treatment of juvenile rheumatoid arthritis. While on salicylate therapy, the patient developed tachypnea and became increasingly hyperthermic, lethargic, and disoriented. The patient developed a maculopapular rash, weakness, and a decreased level of consciousness during the 11 days before admission to the hospital. Physical examination and laboratory determinations revealed that the patient had hypoprothrombinemia, hypoglycemia, and severe hepatic encephalopathy secondary to long-term salicylate toxicity. The patient was treated for hypoglycemia, electrolyte imbalances, thrombocytopenia, and anemia and was discharged after 24 days. Diagnosing chronic salicylism with hepatic dysfunction was difficult because the symptoms are similar to those of stage I to stage II Reye's syndrome. Liver enzymes, including aspartate aminotransferase (also called SGOT), alanine aminotransferase (also called SGPT), alkaline phosphatase, and lactate dehydrogenase, may be elevated in juvenile arthritis patients with hepatic dysfunction. Liver dysfunction usually improves when salicylate therapy is discontinued. Supportive therapy should always be used in symptomatic patients. Children on long-term, high-dose salicylate therapy should be monitored closely, and baseline liver function tests should be performed. The clinical effectiveness of administering sodium bicarbonate in attempts to alkalinize urine and increase salicylate elimination is controversial. In patients with juvenile rheumatoid arthritis who develop chronic salicylism, careful analysis of the patient's medication history, laboratory values, and clinical presentation are necessary to rule out Reye's syndrome.
