The prevalence and activity of human herpesvirus-6 in patients with collagen vascular diseases (CVD) was determined. One hundred and fifty patients with CVD (56 with systemic lupus erythematosus-SLE, 92 with rheumatoid arthritis-RA, 1 with Sharp's syndrome and 1 with atypical polyclonal lymphoproliferation-APL and rheumatoid features) were screened serologically (IFA and ELISA) for antibodies against human herpesvirus-6 (HHV-6), Epstein-Barr virus (EBV) and cytomegalovirus (CMV). Virus isolation was attempted from peripheral blood lymphocytes (PBL) of 25 persons with various disorders. PBL were grown in tissue culture and tested with standard HHV-6-positive antisera for viral antigen expression. Supernatants of the patient's lymphocyte cultures were used to infect HSB2 cells, and virus infection in these cells was proven by IFA, in situ hybridization and by electron microscopy. Fifty-five percent of the SLE patients, 6.5% of the RA patients and both patients with Sharp's syndrome or with APL had antibody titers indicative of active HHV-6 infection. Virus cultures were positive in 9 of the 25 attempts with establishment of stable virus lines. These patients were 5 with SLE or UCVD, and one each with RA, CFS, APL as well as one healthy control. Reactivated and chronic active HHV-6 infections are frequent in SLE like EBV in RA. The role of these viruses in the pathogenesis of the diseases or in their reactivation still needs further investigation.

CFIDS (chronic fatigue and immune disfunction syndrome) is also known as CFS (chronic fatigue syndrome), CEBV (chronic Epstein-Barr virus), M.E. (myalgic encephalomyelitis), yuppie flu and by other names. It is a complex illness characterized by incapacitating fatigue (experienced as exhaustion and extremely poor stamina), neurological problems and a constellation of symptoms that can resemble many disorders, including; mononucleosis, multiple sclerosis, fibromyalgia, AIDS-related complex (ARC) and autoimmune diseases such as lupus. These symptoms tend to wax and wane, but any often severely debilitating and may last for many months or years. All sections of the population (including children) are at risk, but women under 45 seem to be most susceptible. The investigators suggest that CFIDS results from dysfunction of the immune system. The exact nature of this dysfunction is not yet well defined, but it can generally be viewed as an unregulated or overactive state which is responsible for most of the symptoms. There is also evidence of some immune suppression in CFIDS. None of the treatments is consistently satisfactory, but some may be helpful: psychotherapy, physiotherapy, exercise programs, acupunctures, small doses of antidepressants, etc.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating disease causing indefinite fatigue. ME/CFS has long been hypothesised to have an infectious cause; however, no specific infectious agent has been identified. We used metagenomics to analyse the RNA from plasma samples from 25 individuals with ME/CFS and compare their microbial content to technical controls as well as three control groups: individuals with alternatively diagnosed chronic Lyme syndrome (N = 13), systemic lupus erythematosus (N = 11), and healthy controls (N = 25). We found that the majority of sequencing reads were removed during host subtraction, thus there was very low microbial RNA content in the plasma. The effects of sample batching and contamination during sample processing proved to outweigh the effects of study group on microbial RNA content, as the few differences in bacterial or viral RNA abundance we did observe between study groups were most likely caused by contamination and batch effects. Our results highlight the importance of including negative controls in all metagenomic analyses, since there was considerable overlap between bacterial content identified in study samples and control samples. For example, Proteobacteria, Firmicutes, Actinobacteria, and Bacteriodes were found in both study samples and plasma-free negative controls. Many of the taxonomic groups we saw in our plasma-free negative control samples have previously been associated with diseases, including ME/CFS, demonstrating how incorrect conclusions may arise if controls are not used and batch effects not accounted for.
