Reversible total IgA deficiency associated with phenytoin treatment
1Department of Infectious Diseases, Lund University Hospital, Sweden.
Abstract:
A 55-y-old male developed long-standing upper respiratory symptoms during phenytoin treatment of epileptic fits. Complete lack of serum IgA was noted repeatedly. Following replacement of phenytoin, normal IgA levels were found and a slow improvement in respiratory symptoms occurred. Immunoglobulin deficiency, in particular low levels of IgA, are not uncommon among phenytoin treated subjects. The occurrence of frequent respiratory infections in such patients justifies the investigation of immunoglobulin levels.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
