Treatment

According to the pathogenesis of HIVE, treatment should aim at suppressing the viral replication in the CNS. It is an unresolved issue whether the antiviral com- pounds need to penetrate into the CSF. A variety of clinical (Letendre 2004), vi- rological (de Luca 2002), pathological and electrophysiological studies suggest that substances reaching higher CSF concentrations are more effective. In contrast, we found no association of the number of CNS-penetrating substances and their CSF levels with the magnitude of CSF viral load suppression (Eggers 2003). HAART- induced neurocognitive improvement correlates more closely with viral load sup- pression in the CSF than in the plasma (Marra 2003).
In the absence of prospective, controlled, and randomized studies with clinical end points, we consider it important that any antiretroviral regimen in patients with HIVE includes as many as possible CNS-penetrating substances. We suggest any of the following: zidovudine, lamivudine (high concentrations in ventricular CSF; unpublished observations), nevirapine and indinavir. With the substances approved for clinical use in the recent years, CNS penetration is low or unknown.

HIV-associated myelopathy 651



A number of small studies investigated the effect of Selegelin, Nimodipin, Lexipa- fant, and valproic acid for treatment of HIVE. These drugs act on the molecular pathogenesis of HIVE and are used in conjunction with antiretroviral treatment. Although a trend for clinical and neuropsychologic improvement was seen with some substances, none of them can be recommended for clinical routine.
Prognosis: An optimal HAART may lead to significant clinical improvement of HIVE. The extent of improvement includes restoration of working ability in pa- tients previously dependent on caregivers. This effect can be observed for up to four years, in parallel with sufficiently suppressed plasma viraemia (Cysique 2006). During the first months of treatment, the radiological signs of leukoencephalopathy may become more prominent, but eventually regress over the following one to two years.
Autopsy studies and clinical case series show, however, that some patients develop
a clinically apparent CNS disease despite effective HAART-induced suppression of plasma viral load (Brew 2002; own unpublished observations). Even with rapid decrease of plasma viraemia during HAART, many HIVE patients show a signifi-
cantly protracted decrease of the CSF viral load (Eggers 2003). On these grounds
we recommend that in patients with HIVE, the CSF viral load should be determined during the first one or two years of HAART. Modification of the antiviral regimen should be considered when clinical and virologic studies suggest ongoing CNS viral replication with complete suppression of plasma viraemia.


HIV-associated myelopathy

Clinical characteristics

HIV-infected patients may develop a myelopathy without the neuropsychological signs and symptoms of HIVE, labelled HIV associated myelopathy (HIVM). The histopathological hallmark are vacuoles most prominent in the cervical and thoracic parts of the spinal cord and lipid-laden macrophages, hence the term ìvacuolar myelopathyî (Petito 1985). These changes are reminiscent of severe combined de- generation and may occur with HIV-negative patients. As HIV viral products have only inconsistently been shown to be part of the lesions, the role of the virus for the disease is uncertain. Pathogenetically, a disturbance of cobalamin-dependent trans- methylation has been discussed. Like HIVE, HIVM occurs mainly with advanced immunosuppression. Only a proportion of patients with the autoptic finding of vacuolar myelopathy shows clinically apparent myelopathy during life (dal Pan
1994).

Diagnostic workup

A patient may be suspected of having HIVM if he has a spastic-atactic gait, hyper- reflexia with positive Babinski sign, disturbance of sphincter control, erectile dys- funtion, and slight signs of sensory dysfunction in a glove and stocking distribu- tion. The diagnosis of an independent HIVM should only be made when a con- comittant cognitive impairment is significantly less prominent than the myelopathy. Electrophysiological tests which show increased latencies of somatosensory evoked

potentials (SEP) and the motor evoked potentials on transcranial magnetic stimula- tion are compatible with the diagnosis. CSF, microbiological and spinal imaging studies are inconspicuous or unspecific, and they have their importance in the ex- clusion of differential diagnosis, as listed in Table 4. Spinal imaging should include MRI of the cervical and, possibly the thoracic cord.
