BG> "Xerostomia Associated with Didanosine" Lancet (12/19-26/92) Vol.
BG> 340, No. 8834/8835, P. 1542 (Valentine, Chris et al.)
BG> Xerostomia is not a direct result of the use of didanosine (DDI)
BG> to treat AIDS, write Chris Valentine et al. of the Royal Brompton
BG> National Heart and Lung Hospital in London, U.K. Dodd and colleagues
BG> report in the Sept. 26 issue of the Lancet on the association between
BG> DDI treatment and xerostomia. But the true incidence of xerostomia
BG> associated with DDI is probably considerably less than the 35 percent
BG> figure suggested by Dodd et al. Xerostomia has been reported as a
BG> feature of HIV infection, and their group has previously reported
BG> salivary gland abnormalities in HIV-positive patients before DDI was
BG> in clinical use. Because DDI is available in the United States to
BG> treat AIDS in combination with AZT, these patients will usually have a
BG> more advanced stage of HIV infection in which there may be a higher
BG> incidence of xerostamia. Data presented at the Eighth International
BG> Conference on AIDS suggest that this effect is due to the drug rather
BG> than stage of infection. Dodd et al. do not mention whether their
BG> study design allowed them to address the question of whether the
BG> apparent difference in resting saliva production between their
BG> patients receiving DDI and those not may be a result of the effect of
BG> stage of HIV infection rather than the effect of DDI. Dodd et al.
BG> state that DDI is exerting its effect on resting salivary flow by
BG> causing a neuropathy which reduces the normal sympathetic flow to the
BG> gland. However, the researchers conclude it is, instead, more likely
BG> that the effect is more similar to the well-documented effect of DDI
BG> on the pancreas.
