Immunoglobulin Fab Fragments

The American Journal of Tropical Medicine and Hygiene

Single doses (250, 500, 1,000, or 2,000 units/kg) of an ovine polyclonal-specific Fab fragment directed against tumor necrosis factor-alpha (TNF-alpha) were given to 17 adult patients with severe falciparum malaria immediately before treatment with artesunate in a pilot study to assess safety and optimal dosage with a view to future studies. Clinical and laboratory variables were compared with 11 controls. In the groups given Fab, there was a tendency for a faster resolution of clinical manifestations and reduction of fever but also a tendency towards longer parasite clearance times.

CONTEXT: Ashwagandha, a popular Ayurvedic medicine, is now available in the United States. Alkaloids found in this herb have structural similarity with digoxin. OBJECTIVE: To study potential interference of Ashwagandha with serum digoxin measurement by immunoassays. Potential interference was also investigated with immunoassays for 11 other commonly monitored drugs. In addition, interaction of components of Ashwagandha with the Fab fragment of antidigoxin antibody (Digibind) was investigated.
