LEP and vibrio infectious disease: Importantly, our data not only suggest that leptin levels may be associated with cholera, including the level of immune responses to T cell–dependent antigens, but also suggest that leptin levels may remain suppressed for at least a month after clinical recovery from cholera, raising the possibility that the nutritional and immunologic impact of an episode of cholera may extend long after the period of apparent clinical stabilization, rehydration, and resolution of diarrhea.
