"Rheumatoid" subcutaneous nodules that were at one time considered diagnostic of rheumatoid arthritis or rheumatic fever have also been found in individuals withoug known disease, in patients with systemic lupus erythematosus, and in other conditions. In this report, subcutaneous nodules were described in one patient with fibrositis and in another scleroderma. Multiple pathogenic mechanisms are probably responsible for development of these nodules.

Clinical and laboratory test data of 77 patients with systemic lupus erythematosus (SLE) were evaluated by factor analysis. Six factors representing disease patterns were extracted: cutaneous symptoms of alopecia, malar rash, rash and photosensitivity; renal involvement; the anticoagulant syndrome of phlebitis and partial thromboplastic time inversely related to platelet count; lymphopenia; viral or fibromyalgia symptoms of headache, nervousness, joint and muscle pain; and serology of anti-DNA antibodies and complement inversely related. Application of factor analysis reveals various clinical presentations of SLE.

This study was designed to determine the prevalence and clinical significance of hyperprolactinemia in systemic lupus erythematosus (SLE) and other rheumatic diseases. Basal levels of prolactin were determined in 130 nonselected sera from patients with rheumatic diseases including 45 with SLE, 31 with rheumatoid arthritis, 23 with osteoarthritis, 18 with fibromyalgia, and 13 with polymyalgia rheumatica. Serum samples of 28 healthy subjects were used as normal controls. Serum prolactin was measured by radioimmunoassay. ANA, anti-DNA, RNP, Sm, Ro, La, and anticardiolipin antibodies were determined by standard techniques. Elevated serum levels of prolactin (PRL greater than 20 ng/ml) were found in a subset of SLE patients. In addition, a direct correlation with clinical disease and serological (ANA) activity was also found. These findings suggest a potential role for this immunoregulatory hormone in SLE pathogenesis.

Cells of the immune system synthesize prolactin and express mRNA and receptors for that hormone. Interleukin 1, interleukin 6, gamma interferon, tumor necrosis factor, platelet activator factor, and substance P participate in the release of prolactin. This hormone is involved in the pathogenesis of adjuvant arthritis and restores immunocompetence in experimental models. In vitro studies suggest that lymphocytes are an important target tissue for circulating prolactin. Prolactin antibodies inhibit lymphocyte proliferation. Prolactin is comitogenic with concanavalin A and induces interleukin 2 receptors on the surface of lymphocytes. Prolactin stimulates ornithine decarboxylase and activates protein kinase C, which are pivotal enzymes in the differentiation, proliferation, and function of lymphocytes. Cyclosporine A interferes with prolactin binding to its receptors on lymphocytes. Hyperprolactinemia has been found in patients with systemic lupus erythematosus. Fibromyalgia, rheumatoid arthritis, and low back pain patients present a hyperprolactinemic response to thyrotropin-releasing hormone. Experimental autoimmune uveitis, as well as patients with uveitis whether or not associated with spondyloarthropathies, and patients with psoriatic arthritis may respond to bromocriptine treatment. Suppression of circulating prolactin by bromocriptine appears to improve the immunosuppressive effect of cyclosporine A with significantly less toxicity. Prolactin may also be a new marker of rejection in heart-transplant patients. This body of evidence may have an impact in the study of rheumatic disorders, especially connective tissue diseases. A role for prolactin in autoimmune diseases remains to be demonstrated.

Deposits of IgG localized to collagen bundles/extracellular matrix components occurred in skin biopsies from patients with primary fibromyalgia (PF). None of these patients demonstrated a positive lupus band test. Control skin biopsies from healthy controls were negative but showed intense reactivity for IgG after collagenase treatment. PF-skin attached both homologous and heterologous serum IgG in indirect immunofluorescence, which may point to a qualitative alteration of dermal matrix components in PF. Skin from patients with systemic lupus erythematosus and rheumatoid arthritis showed a lower dermal fluorescence intensity than in PF patients. The cause of the presence of IgG in dermal tissue from PF patients is unclear. It may be caused by a non-specific attachment of IgG to the extracellular matrix related, for example, to tissue hypoxia and/or increased capillary leakage due to an increased number of mast cells in the PF-skin.

Development of diagnostic criteria for juvenile rheumatoid arthritis, systemic lupus erythematosus, a juvenile dermatomyositis, as well as advances in molecular biology, have assisted epidemiologic study of the rheumatic disorders of childhood. It may be misleading to extrapolate the incidence and prevalence of pediatric forms of arthritis from population studies of adults. Additional study of the frequency of childhood musculoskeletal disorders is very much needed. Classification criteria for Kawasaki syndrome, fibrositis in children, and the juvenile spondyloarthropathies are also desirable.

Self-report questionnaire scales to assess various constructs of health status were compared in 602 patients with five rheumatic diseases, including 134 rheumatoid arthritis (RA), 216 osteoarthritis (OA), 84 fibromyalgia, 124 systemic lupus erythematosus (SLE), and 43 scleroderma patients. RA patients showed significantly higher degrees of difficulty, dissatisfaction, and pain in performing eight activities of daily living (ADL) compared to patients with the other four diseases (P less than 0.01), while SLE patients reported the least difficulty, dissatisfaction and pain. Fibromyalgia patients showed significantly higher scores on a visual analog pain scale than patients with the other four diseases (P less than 0.05), followed by OA patients. Fibromyalgia patients reported significantly higher levels of learned helplessness, assessed according to a rheumatology attitudes index (RAI), than patients with all other diseases, and scleroderma patients showed significantly lower RAI scores (P less than 0.05). Patients with all five diseases who had not completed high school showed poorer clinical status than patients who had completed high school on all six scales. Significant differences in questionnaire scores were seen for 24 of 30 comparisons (five diseases and six scales) according to formal education level, versus only two according to age, and none according to duration of disease.

Patients eventually diagnosed as having the fibromyalgia syndrome often have symptoms which suggest alternate diagnoses such as peripheral neuropathy, spondylitis, metabolic myopathy, polymyalgia, early rheumatoid arthritis, early systemic lupus erythematosus or a chronic fatigue syndrome. Delay in diagnosis of fibromyalgia often proves costly and frustrating to the patient and may lead to inappropriate therapy.

Seventeen families of patients with primary fibromyalgia were studied for evidence of inherited primary fibromyalgia. Fifty parents and siblings were included in the analysis. Twenty-six (52%, mean age 33.5 years) had characteristic symptoms and findings of primary fibromyalgia. Eleven (22%, mean age 28 years) were asymptomatic but had clinical evidence of abnormal muscle consistency to palpation without tender or trigger points. One person had clinical evidence of lupus. Thirteen (26%) had no evidence of fibromyalgia or abnormal muscle consistency. The mode of inheritance was autosomal dominant. Identical twins are described who developed symptoms of primary fibromyalgia within six months of each other, as are two brothers who developed abnormal palpable muscle consistency years before acquiring the characteristic findings of the fibromyalgia syndrome. Primary fibromyalgia may be an inherited condition with a variable latent stage before clinical expression of the disease.

Consultation-liaison psychiatry has contributed much to our understanding of the psychological complications of physical illness, both in general responses to illness and in particular problems related to specific diseases. We reviewed 100 psychiatric consultations from a specialized rheumatology unit. Eighty percent of the consultations consisted of patients with systemic lupus erythematosus (36%), rheumatoid arthritis (29%), and fibrositis (15%). The majority of S.L.E. patients had organic brain syndromes related to central nervous system involvement or corticosteroids, while the majority of rheumatoid arthritis patients had a depressive diagnosis. Fibrositis patients showed no specific psychiatric diagnosis. Some future areas of research for consultation-liaison psychiatry in this area are suggested.
