Micronutrient malnutrition is usually highly prevalent in areas endemic for Chagas disease. Nevertheless, the contribution of micronutrient deficiency to the immunopathology of this infection is often overlooked. In the present work, we assessed the effects of vitamin E deficiency on acute Trypanosoma cruzi (Y strain) infection of Holtzman rats. At 20 days post infection, vitamin E deficiency induced changes in leukocyte levels and exacerbated the myocarditis and sympathetic denervation of ventricular hearts. Vitamin E-deficient infected rats displayed significant leukopenia, evidenced by the decline in the numbers of CD45RA(+)CD3(-) B-cells and CD3(+)CD4(+) T-lymphocytes in the peripheral blood compared with infected control rats. In contrast, vitamin E deficiency induced monocytosis as well as an increased differentiation rate of monocytes to macrophages, as revealed by immunohistochemical analysis.

The myocarditis associated with reovirus in commercial turkeys was studied retrospectively. Fifty-two cases were identified between 1991 and 2009. The lesions occurred in four different poultry companies in California and affected male and female turkeys with an average age of 19 days. Increased mortality in the turkey flocks ranged from 0.35% to 3% per week in 47 cases. Reovirus was isolated from the heart in 14 out of 19 cases. Twenty-four out of 28 birds from nine cases had low vitamin E levels in the liver ranging from 0.29 to 2.5 ppm (normal 3.0 to > or = 15 ppm). Transmission electron microscopy of the heart revealed degenerative changes in the myocardial cells. Reovirus has been suggested as a probable etiology of this condition. Vitamin E deficiency might also contribute to the development of the lesions.
