Levels of serum immunoglobulins were measured in healthy Vietnamese and in leprosy patients. Healthy Vietnamese had higher levels of IgG, IgA, IgM, and IgE than did healthy Dutch controls, as well as higher levels of three of the four subclasses of IgG (IgG1, IgG2, IgG3). Lepromatous leprosy patients had significant increases in all classes and subclasses of immunoglobulins, except for IgG2, in comparison with local controls. Tuberculoid leprosy patients had more IgG1, IgG3, and IgG4 than did local controls and had higher total IgG levels. The patients had no increase in autoantibodies against tissue antigens compared to local or Dutch controls.
