In this study, we evaluated pain sensitivity in patients with fibromyalgia or other types of chronic, diffuse musculoskeletal pain to establish whether fibromyalgia represents the end of a continuum of dysfunction in the nociceptive system. One hundred and forty five patients and 22 healthy subjects (HS) completed an epidemiological questionnaire to provide(More)
OBJECTIVE Alexithymia, a lack of emotional awareness, is common in chronic pain patients. The aim of the study was to investigate the relationship of alexithymia to ongoing pain, experimental pain sensitivity, and illness behavior in patients with chronic musculoskeletal pain. METHODS Sixty-eight women with fibromyalgia (age: average, 43.4 years; range,(More)
An application of the Southern blot technique is described which permits the detection of DNA fragmentation due to cell death by apoptosis. DNA fragments were isolated from cell suspensions and tissues, separated on agarose gel, transferred by Southern blot and hybridized with a radiolabeled total cellular DNA probe. The application of this procedure to(More)
We analysed the role of dosage, route and frequency of administration of clinical grade interferon-beta (IFN-beta) preparations in inducing anti-IFN-beta antibodies (IFN-beta-Abs) in 5 groups of relapsing-remitting multiple sclerosis (RRMS) patients who were respectively treated as follows: 1) weekly intramuscular (i.m.) injections of 30 mg of recombinant(More)
We analysed the kinetics and clinical impact of binding antibodies (BAbs) and neutralizing antibodies (NAbs) to three interferon beta (IFNbeta) products in patients with relapsing-remitting MS (RRMS). Patients with RRMS received IFNbeta-1b 8 MIU subcutaneously (SC) every other day, intramuscular (IM) IFNbeta-1a 30 mcg once weekly, or SC IFNbeta-1a 22 mcg(More)
Immunodominance is a complex phenomenon that relies on a mere numerical concept, while being potentially influenced at every step of the immune response. We investigated the mechanisms leading to the establishment of CTL immunodominance in a retroviral model and found that the previously defined subdominant Env-specific CD8(+) T cells are endowed with an(More)
BACKGROUND interferon beta (IFN-beta) reduces relapse rate and disease progression in patients with the relapsing-remitting form of multiple sclerosis (RRMS). IFN-beta may act by upregulating the expression of anti-inflammatory components of the immune system. OBJECTIVES To determine whether weekly intramuscular (i.m.) injection of IFN-beta1a had a short-(More)
Gonadal hormones are known to be affected by morphine and other opioids. In this paper, we summarize data collected in recent years which clearly indicate that the opioid-induced effects on steroid hormones depend on the opioid used and in some cases on the sex of the subject. Indeed morphine is able to reduce hormones like testosterone and cortisol in both(More)
B-cell-type chronic lymphocytic leukemia (B-CLL) patients have immunological abnormalities of both B and T lymphocytes. Since T cell defects might depend upon a defective accessory function of neoplastic B lymphocytes, we analyzed the ability of peripheral blood B cells of seven B-CLL patients to stimulate allogenic normal T cells in mixed lymphocyte(More)
