Liposyn infusion increases plasma prostaglandin concentrations.

To determine whether Liposyn infusion results in increased plasma prostaglandin (PG) concentrations, the following study was performed in 33 adult rabbits with chronically implanted arterial and venous catheters. Plasma PG concentrations were determined by radioimmunoassay for two vasodilators, PGE2 and PGI2 (as measured by its metabolite 6-keto-PGF1 alpha), and two vasoconstrictors, thromboxane (TX) A2 and PGF2 alpha, as measured by their metabolites TXB2 and PGF2 alpha-M, respectively. A 1-hour infusion of Liposyn at 4 ml per kg resulted in statistically significant increases in arterial and venous concentrations of PGE2 and 6-keto-PGF1 alpha (p less than 0.001) and of TXB2 (p less than 0.04). There were no significant changes in PGF2 alpha-M plasma concentrations. Liposyn infusion also resulted in a small but statistically significant increase in PaO2 of 4.7 +/- 1.5 torr (p less than 0.01). It is concluded that Liposyn infusion results in statistically significant increases in plasma concentrations of PGE2, 6-keto-PGF1 alpha, and TXB2.

Pirprofen (Rengasil) in the treatment of juvenile rheumatoid arthritis. A segment I study.

Thirty-two patients with JRA were enrolled in a 4-wk open-labeled, non-controlled multicentre trial of pirprofen. An initial dose of about 300 mg/m2/d (range 250-330) was gradually increased to a maximum of 600 mg/m2/d (range 413-761). The medication was provided as an aqueous suspension (10 mg/ml), and was given 4 times/d. Efficacy analysis showed significant decreases occurred in the DMS, travel time, grip strength, and the severity of swelling score (in all cases p less than 0.05 based on the paired Student t test, 2-tailed). Nineteen patients reported a total of 27 adverse experiences; 6 of which were attributable to pirprofen. At the study dosages used pirprofen seems to be very similar in efficacy and safety to other nonsteroidal antiinflammatory drugs investigated in children with JRA.

Juvenile dermatomyositis (JDMS): new clues to diagnosis and pathogenesis.

The localization of focal inflammatory myopathy (IM) is aided by MRI, which facilitates diagnostic testing (muscle biopsy or EMG). Antibodies to antigens involved in protein synthesis are specific for IM and characterize distinct subsets of adult IM, but are rare in pediatric IM. In definite juvenile dermatomyositis, serological indicators of disease activity include neopterin and von Willebrand factor antigen, markers of macrophage activation, and endothelial cell damage, respectively; nailfold capillarioscopy documents small blood vessel involvement. Monitoring the percentage of circulating B cells may indicate the response to therapy.

Atypical Pneumocystis carinii pneumonia in a child with hyper-IgM syndrome.

Children with hyper-immunoglobulin M (hyper-IgM) syndrome are at increased risk for Pneumocystis carinii pneumonia (PCP), an opportunistic infection often found in immunodeficient hosts. PCP can present with increasing hypoxia, fever, cough, and respiratory distress. We describe a child with hyper-IgM syndrome in whom bronchoalveolar washings were negative for PCP. However, there was an atypical lung response in which caseating granulomas predominated. The histopathology, resembling that found in tuberculosis, stresses the importance of a high index of clinical suspicion and histologic confirmation for early intervention and treatment. Immunocompromised children with rapidly progressive pulmonary disease may require lung biopsy and stains such as GMS to identify PCP.
