Plausibly, the same impaired immunity that leads to reactivation of V.Z. and atypical shingles manifesting as ME/CFS would also tend to let loose other infections and thereby confound diagnosis.

The problem with making a case for the chicken pox virus (V.Z. or H.Z.) as a cause of ME/CFS is that the virus is endemic and infection is lifelong if usually asymptomatic. Most researchers will reject it as unworthy of closer inquiry.

Moreover, blood tests are seen as a poor indicator of V.Z. levels, with cerebrospinal fluid samples seen as required for definitive proof. That is usually avoided since it means imposing the risks and pains of a spinal tap.

Since central nervous system (CNS) involvement is now known to be common in chicken pox (about 40% of all cases), a large proportion of the population must be regarded as susceptible to CNS effects when shingles develops along the same neural pathways. Yet CNS effects are rarely noted in shingles. Might it be that such cases are instead recorded as ME/CFS?

"Distinct Cerebrospinal Fluid Proteomes Differentiate Post-Treatment Lyme Disease from Chronic Fatigue Syndrome"

http://www.ncbi.nlm.nih.gov/pubmed/21383843

Abstract

BACKGROUND:

Neurologic Post Treatment Lyme disease (nPTLS) and Chronic Fatigue (CFS) are syndromes of unknown etiology. They share features of fatigue and cognitive dysfunction, making it difficult to differentiate them. Unresolved is whether nPTLS is a subset of CFS.

METHODS AND PRINCIPAL FINDINGS:

Pooled cerebrospinal fluid (CSF) samples from nPTLS patients, CFS patients, and healthy volunteers were comprehensively analyzed using high-resolution mass spectrometry (MS), coupled with immunoaffinity depletion methods to reduce protein-masking by abundant proteins. Individual patient and healthy control CSF samples were analyzed directly employing a MS-based label-free quantitative proteomics approach. We found that both groups, and individuals within the groups, could be distinguished from each other and normals based on their specific CSF proteins (p<0.01). CFS (n = 43) had 2,783 non-redundant proteins, nPTLS (n = 25) contained 2,768 proteins, and healthy normals had 2,630 proteins. Preliminary pathway analysis demonstrated that the data could be useful for hypothesis generation on the pathogenetic mechanisms underlying these two related syndromes.

CONCLUSIONS:

nPTLS and CFS have distinguishing CSF protein complements. Each condition has a number of CSF proteins that can be useful in providing candidates for future validation studies and insights on the respective mechanisms of pathogenesis. Distinguishing nPTLS and CFS permits more focused study of each condition, and can lead to novel diagnostics and therapeutic interventions.
