41 children with juvenile rheumatoid arthritis (JRA) and 6 with postinfectious arthropathies, aged 3--15 years, were treated with acetylsalicylic acid for 14 days during which time the patients were hospitalized. Three different acetylsalicylic acid preparations were used: a microencapsulated form, an enteric-coated form and standard acetylsalicylic acid tablets. Serum salicylate concentrations were measured by Trinder's photometric method. With doses of 90--120 mg/kg/day symptoms of salicylism appeared in about 50% of the cases. Daily doses of 2 g/m2 (not exceeding 70 mg/kg) proved relatively safe in this study, whereas symptoms and signs of intoxication appeared at doses exceeding 3 g/m2/day. In this respect there were no significant differences between the three acetylsalicylic acid preparations used. The results of this study also suggest that the serum salicylate concentrations should not exceed 2000 mumol/l (about 27 mg/100 ml). The symptoms of salicylism correlated closely with serum salicylate levels, which, in turn, correlated well with the dosage in g/m2. Elevation of serum aspartate aminotransferase was noted in 1/3 of the cases. All of these had a dose exceeding 2 g/m2, and the frequency of elevated enzyme activities increased with increasing dosage. In the group receiving enteric coated form of acetylsalicylic acid, there were fewer positive benzidine tests (12%) than in the two other groups (22--28%).

To evaluate the adverse effects associated with long-term methotrexate (MTX) therapy in children with juvenile rheumatoid arthritis, we conducted a retrospective review of 62 patients with polyarticular juvenile rheumatoid arthritis, treated from 84 to 296 weeks with MTX weekly. Pulmonary function testing was performed before MTX therapy on 46 patients older than 6 years of age; 26 patients had serial pulmonary function testing, and no abnormalities were detected. In all 62 patients, liver function (alanine aminotransferase and aspartate aminotransferase activity) was monitored every 3 months. Transient liver function abnormalities developed in nine patients during treatment. Twelve patients underwent percutaneous liver biopsies after receiving 815 to 2980 mg of MTX; none had fibrosis or cirrhosis. Macrocytic anemia developed in one child receiving simultaneous long-term trimethoprim-sulfamethoxazole therapy and resolved after the trimethoprim-sulfamethoxazole was discontinued. No stomatitis or rashes were observed. Six patients were able to discontinue MTX therapy when their disease remitted; 56 continue MTX therapy. No child permanently discontinued MTX therapy because of an adverse effect. These data suggest that MTX may be better tolerated in children with juvenile rheumatoid arthritis than in adults with rheumatoid arthritis.

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.

Macrophage activation syndrome is a form of secondary haemophagocytic lymphohistiocytosis seen in the context of rheumatic diseases. It is seen most frequently in association with systemic onset juvenile arthritis or childhood Still's disease. Hemophagocytosis is part of a sepsis-like clinical syndrome caused by hypercytokinemia due to a highly stimulated but ineffective immune response. Coagulopathy and hemorrhages, decreased white cell count, elevated levels of aspartate aminotransferase, fever, rash, hepatosplenomegaly and central nervous system dysfunction are some of diagnostic criteria of macrophage activation syndrome, but it is very difficult to diagnose due to the lack of specific clinical signs. We report a 8-year-old child who was admitted to the ICU with lethargy, fever, acute respiratory failure, coagulopathy, metabolic acidosis and multiorgan failure. Septic shock was suspected, but he was diagnosed with macrophage activation syndrome and treated with corticosteroids and intravenous immunoglobulin and later discharged from the ICU.
