An article in the July issue on latent treatment for TB infection using two months of rifampin and pyrazinamide should have stated that Edward Nardell, MD, was speaking of his experience at The Cambridge Hospital, and at his own TB clinic, where two patients of hepatitis were hospitalized. The patient in a third case, in Framingham, MA, was not hospitalized. In addition, Nardell is state TB control officer; and associate professor at Harvard Medical School. The halt on treatment with the two drugs applies only to Nardell’s clinic.
