To test the hypotheses of modern human origin in East Asia, we sampled 12,127 male individuals from 163 populations and typed for three Y chromosome biallelic markers (YAP, M89, and M130). All the individuals carried a mutation at one of the three sites. These three mutations (YAP+, M89T, and M130T) coalesce to another mutation (M168T), which originated in(More)
OBJECTIVE To measure soluble factors having a possible role in fibromyalgia (FM) and compare the profiles of patients with recent onset of the syndrome with patients with chronic FM. METHODS The production of cytokines, cytokine-related molecules, and a CXC chemokine, interleukin (IL)-8, was examined. Fifty-six patients with FM (23 with <2 yr and 33 with(More)
OBJECTIVE To evaluate abatacept therapy in patients with non-life-threatening systemic lupus erythematosus (SLE) and polyarthritis, discoid lesions, or pleuritis and/or pericarditis. METHODS In a 12-month, multicenter, exploratory, phase IIb randomized, double-blind, placebo-controlled trial, SLE patients with polyarthritis, discoid lesions, or pleuritis(More)
Elevated spontaneous IgG production is characteristic of SLE. To identify the factors that support it, IL-6, a cytokine with an important role in the differentiation of IgG-secreting cells, was studied in SLE patients. Higher than normal levels of IL-6 were found, by a B9 assay, in sera of 63 of 70 patients (p less than 0.05). IL-6 was detected in 36 of 37(More)
OBJECTIVES To determine the frequency, accrual, attribution and outcome of neuropsychiatric (NP) events and impact on quality of life over 3 years in a large inception cohort of patients with systemic lupus erythematosus (SLE). METHODS The study was conducted by the Systemic Lupus International Collaborating Clinics. Patients were enrolled within 15(More)
Systemic lupus erythematosus (SLE) is the prototype of human autoimmune diseases. Its genetic component has been suggested by familial aggregation (lambdas = 20) and twin studies. We have screened the human genome to localize genetic intervals that may contain lupus susceptibility loci in a sample of 188 lupus patients belonging to 80 lupus families with(More)
To evaluate the association of alleles of regions having regulatory potential in the IL-6 gene, with SLE, the AT-rich minisatellite in the 3′ flanking region and the 5′ promoter-enhancer of the IL-6 gene were genotyped by PCR- and RFLP-based methods. The AT-rich minisatellite allele distribution pattern was significantly different in SLE (n = 146) as(More)
Six hundred nine private patients with systemic lupus erythematosus were followed up for a mean of ten years. Ninety percent were female; 79% were white. Three hundred sixty-nine received diagnosis before 1970, and 234 after. Three hundred seventy-nine did not have nephritis; 230 did. The overall ten-year survival was 79% (87% without nephritis, 65% with(More)
Five hundred seventy lupus erythematosus patients observed in a private practice between 1980 and 1989 were surveyed. Fifty-five percent were diagnosed after 1980. Five hundred three fulfilled criteria for systemic lupus erythematosus ( [SLE]; 464 idiopathic, 23 overlap, 16 drug-induced) and 67 had biopsy-documented cutaneous (discoid) lupus. In the(More)
OBJECTIVE To examine, in an inception cohort of systemic lupus erythematosus (SLE) patients, the association between neuropsychiatric (NP) events and anti-ribosomal P (anti-P), antiphospholipid (lupus anticoagulant [LAC], anticardiolipin), anti-beta2-glycoprotein I, and anti-NR2 glutamate receptor antibodies. METHODS NP events were identified using the(More)
