The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) associated with localized herpes zoster is rarely reported and may be under-appreciated. We describe two diabetic men with herpes zoster ophthalmicus (HZO) who developed hyponatremia (114 and 116 mmol/L) during acute illness. Both were euvolemic and had elevated urine osmolality (435 and 368 mmol/kg.H(2)O) and sodium (Na(+)) concentration (61 and 63 mmol/L) along with normal cardiac, renal, liver, and endocrine function consistent with the diagnosis of SIADH. Thorough investigation for other causes of SIADH, including detailed physical examination, laboratory studies, and computed tomography of the brain, chest, and abdomen, were negative. Despite antiviral therapy (acyclovir) for herpes zoster, ophthalmoplegia, keratitis, and post-herpetic neuralgia (PHN) developed. Even with fluid restriction and high salt diet, SIADH lasted for 3 to 4 months and resolved concomitantly with resolution of PHN, suggesting an association between SIADH and HZO. These two cases raise the potential for herpes zoster infection, especially HZO, to involve the regulatory pathway of ADH secretion, contributing to SIADH. The presence of PHN, which reflects greater neural damage may, at least in part, explain the prolonged ADH secretion and hyponatremia.

MAP kinases JNK and p38 play an important role in many immune and inflammatory processes, whereas glucocorticoids exert immunosuppressive and anti-inflammatory activities. We found previously that activation of p38 or JNK inhibits glucocorticoid receptor (GR)-mediated transcriptional activation of a mouse mammary tumor virus (MMTV) promoter-driven luciferase construct in HeLa cells. It appears that this effect is DNA regulatory element-specific, since p38 or JNK activation stimulates GR-dependent transcription from TAT3-ADH promoter-luciferase construct in the same cells. The apparent promoter-specificity of this action suggests that not all glucocorticoid-activated genes are negatively regulated by p38 or JNK. Using different MMTV/TAT3 chimeric reporters we demonstrate that the presence of other accessory binding sites of the MMTV construct contributes to the inhibitory effect of activated p38 or JNK on the MMTV-driven transcriptional activity; and diminishes, but does not reverse the stimulation observed using the TAT GREs from the TAT3-ADH promoter-luciferase construct. On the other hand, comparison of the effects of GRE sequences, either in isolation or in the context of the MMTV LTR accessory binding sites, demonstrates that the responsiveness of the GR depends on the GRE sequence; indicating that in addition to transcription factors bound nearby, interaction with the DNA itself modulates GR activity.
