Vidarabine was evaluated in renal transplant patients as a potential therapeutic agent in
cytomegalovirus
(CMV) infection. Four patients received vidarabine on an open protocol, then ten additional patients were enrolled in a double-blind protocol. Among the nine patients who received vidarabine, no notable clinical improvement occurred in either the vidarabine- or placebo-treated groups. Thus, vidarabine showed no therapeutic effect in the treatment of CMV infections at the dosages used. Four patients showed dramatic CNS deterioration within several days of the onset of vidarabine therapy. Tremors and myoclonus were common, and one patient had unusual brain pathologic changes with widespread neuronal chromatolysis. The pathologic findings in the brain in the other three patients were complex and included intracerebral hemorrhage,
Fabry's disease
, coccidioidomycosis meningitis, and cerebral vascular occlusion. Thus, there was no conclusive proof that vidarabine contributed to the sudden neurologic deterioration of these patients.

In Werdnig-Hoffman disease, mannosidosis, and Hurler's syndrome, two groups of neurons (the Onuf's and intermediomedial nuclei) in the ventral horn of the mid-sacral region are found to share common selective sparing or vulnerability with the intermediolateral nuclei of the thoracolumbar and sacral regions of the spinal cord. This finding confirms the previous observations on the characteristic involvement or sparing in
Fabry's disease
(14), Shy-Drager syndrome (17), amyotrophic lateral sclerosis, anterior poliomyelitis, and neuronal intranuclear hyaline
inclusion disease
(15), and supports the assumption that the Onuf's and intermediomedial nuclei in the ventral horn represent autonomic neurons much as the thoracolumbar and sacral intermediolateral nuclei.

Sustained transgene expression will be required for the successful treatment of most genetic diseases being considered for gene therapy. The initially high levels of expression attained with plasmid DNA (pDNA) vectors containing viral promoters, such as that from
cytomegalovirus
(CMV), decline precipitously to near-background levels within two to three weeks. Here we constructed pDNA vectors containing the human cellular UBB (encoding ubiquitin B; Ub) promoter and evaluated their expression in the mouse lung. Cationic lipid-pDNA complexes were instilled intranasally (IN) or injected intravenously (IV) into immunodeficient BALB/c mice. Chloramphenicol acetyltransferase (CAT) reporter gene expression from the UBB promoter was initially very low at day 2 post-administration, but by day 35 exceeded the level of expression attained from a CMV promoter vector by four- to ninefold. Appending a portion of the CMV enhancer 5' of the UBB promoter (CMV-Ub) increased CAT expression to nearly that of the CMV promoter and expression persisted in the lung for at least 3 months, with 50% of day 2 levels remaining at day 84. In the liver, expression from the CMV-Ub hybrid promoter was sustained for 42 days. As previous studies have shown that eliminating immunostimulatory CpG motifs in pDNA vectors reduces their toxicity, we constructed a CpG-deficient version of the CMV-Ub vector expressing alpha-galactosidase A, the enzyme deficient in
Fabry disease
, a lysosomal storage disorder. After IN or IV administration, levels of alpha-galactosidase A from this vector were not only undiminished but increased 500% to 1500% by day 35. Our results indicate that CpG-reduced plasmid vectors containing a CMV-Ub hybrid promoter may provide the long-term expression required for a practical gene therapeutic.
