Six patients were studied to evaluate the efficacy and safety of plasma exchange (PE) in the treatment of primary biliary cirrhosis (PBC). All patients were affected by PBC at stage III-IV and presented symptoms refractory to pharmacologic therapy. Patients underwent PE for a mean period of 40 weeks (range 10-88). A mean of 33 liters (range 17-64) of plasma per patients was removed. Patients reported less fatigue (4/6), pruritus (5/5), nausea (3/3), Sjogren's syndrome (2/6), and painful neuropathy (2/3). A reduction of xanthomata was noted in one of the three affected patients. Definitive improvement was seen in the patient with Raynaud's phenomenon. A significant reduction was noted for serum cholesterol and gammaglobulins. ALT, AST, gamma-GT, alkaline phosphatase, bilirubin, prothrombin activity, AMA titers were not affected by PE. All patients suffered some mild adverse effects during PE. Two patients (IV stage) developed late edema and ascites after 34 and 44 weeks of treatment. We conclude that PE can be considered effective chronic treatment for advanced symptomatic PBC refractory to pharmacological therapy.

Primary biliary cirrhosis (PBC) is a chronic nonsuppurative, destructive cholangitis, whose etiology is unknown. Morbidity arises early from pruritus and later from hypercholesterolemia with xanthoma formation. Therapy is supportive and directed at the complications of cholestasis. Plasmapheresis has been reported to benefit patients with hyperlipidemia and PBC; thus a pilot study of plasmapheresis utilizing the Haemonetics Model 30 with replacement by albumin and saline was conducted. Five patients (four female and one male) with a mean age of 43 (range 29-58) and a mean duration of illness of 9.5 years (range 6-21) with marked jaundice, xanthomas, xanthelasma, hepatomegaly, fatigability, anorexia, and pruritus, as well as mild nausea were studied. Peripheral neuropathy was present in two patients. Two patients had splenomegaly. Two patients had an associated Sjogren syndrome. All patients had high serum bilirubin, alkaline phosphatase, and cholesterol levels and mild elevations in aspartate amino transferase and alanine amino transferase activities. Immune complexes measured in four patients were present. Antimitochondrial antibody titers were significant in all patients. Patients underwent a mean of 63 plasmapheresis procedures over a mean of 112 weeks removing a mean of 94.7 liters of plasma. No serious toxicity was seen. All patients showed a reduction in pruritus, xanthomas, xanthelasmas, and serum cholesterol values. The two patients who had evidence of Sjogren syndrome noted subjective improvement. All patients who had fatigue, anorexia and nausea also noted moderate improvement. There was no change in hepatomegaly or splenomegaly in patients demonstrating such organomegaly. Liver function did not change significantly. Overall, four patients had improvement in their condition and one patient achieved stability.(ABSTRACT TRUNCATED AT 250 WORDS)

Over 100 cases of disorders closely resembling classic autoimmune diseases have been reported among patients who were injected or implanted with a diverse group of chemicals including paraffins, vegetable oils or silicone. Most cases have occurred in silicone breast implant recipients, especially those who received their prostheses 2-10 years prior to onset of symptoms. A high proportion of patients exhibit classic signs and symptoms of Sjogren's syndrome or scleroderma. Affected patients typically experience some combination of fatigue, myalgia, joint pain, sicca syndrome (dry eyes and mouth), synovitis, rash, alopecia, muscular weakness or lymphadenopathy, and autoantibody formation. Less commonly, patients may have the CREST syndrome (calcinosis, Raynaud's phenomena, esophageal hypomotility, sclerodactyly and telangiectasias), hypertension, pulmonary fibrosis, or central nervous system pathology.

Sjogren's syndrome (SS) is an autoimmune disease characterized by a chronic inflammatory response mainly localized to the lacrimal and salivary glands. However, it sometimes involves extraglandular organs culminating in systemic disorders. Hematological abnormalities are not uncommon, although they rarely have clinical significance. In this study we examined 99 patients with primary SS who visited our hospital during 1989 to 1999. Patient's mean age was 54.1 years and 95 out of 99 were female. Lymphopenia and leukopenia was noted in 35 patients (35.3%) and 26 patients (26.2%) respectively, and 7 patients (7.1%) had thrombocytopenia. 43 patients (43.4%) had either of these hematological abnormalities. Patients with lymphopenia showed significantly low frequency of arthralgia and anti-SS-A/B antibody was more common in this group. Only one patient in this group required prednisolone therapy because of polyarthritis and general fatigue while others needed no specific therapy. Patients with thrombocytopenia were significantly younger and a male/female ratio was higher than those without this abnormality. They had higher tendency to accompany with skin eruption, positive anti-SS-B antibody, anti-nuclear antibody and rheumatoid factor. Three out of 8 patients with thrombocytopenia were treated with prednisolone according to the protocol for idiopathic thrombocytopenic purpura. All of 3 patients had positive PA-IgG and normocellular bone marrow. Autoimmune mechanism such as polyclonal B cell activation may play a role in the pathogenesis of thrombocytopenia.

The purpose of this qualitative research was to explore the lived experiences of women with Sjogren's Syndrome (SS), a chronic autoimmune syndrome in which invading lymphocytes attack moisture-producing glands of the body. This syndrome, affecting 4 million Americans, involves extreme dryness of the eyes and mouth and other systemic complications such as fatigue and muscle and joint pain. Ten women, ranging in age from 27 to 83, with SS were interviewed to understand their coping strategies and attitudes. This study used Strauss' framework to view the quality of life of the chronically ill-specifically, those with SS. Nine questions were asked to elicit information on limitations with daily living, relationships, emotions about lifestyle changes, and comparisons with others living with chronic disease. In addition to SS, 8 of the 10 women also had fibromyalgia, and 4 had other conditions such as lupus and rheumatoid arthritis (secondary Sjogren's). Their responses were categorized into four groups: helping, hindering, hoping, and hurting. This led to the development of the 4H Model of Chronic Autoimmune Disease with subcategories such as: supporting, joining, comparing, coping, health promoting, fearing, becoming a chronic sufferer, feeling, wishing, appearing, impeding, restricting, isolating, suffering, doctoring, and diagnosing.

Systemic lupus erythematosus (SLE), Sjogren's syndrome (SS), and dermatomyositis (DM)/polymyositis (PM) may be encountered in geriatric patients due to improved survival rates in patients with younger ages of onset or from elderly-onset (EO) disease. EO disease accounts for up to 20% of patients affected by these disorders, and is typically insidious rather than acute. Whereas SS and DM/PM are considered autoimmune diseases with distinct organ specificity, SLE is a systemic disorder that may affect multiple organ systems. Commonly used clinical and laboratory criteria for defining and diagnosing these diseases were largely developed for patients age <65, and need to be modified in the geriatric patient. Therapeutic strategies include attention to ongoing drug regimens, medical comorbidities, and the roles of fatigue, depression, and arthropathy. Each disease may be responsive to low-dose corticosteroids, with a role for first or second-line immunosuppressives as steroid-sparing agents.

Gulf War syndrome (GWS) is a perplexing multi-symptom condition comprising a constellation of signs and symptoms consistently described in the literature. These include muscle fatigue and tiredness, malaise, myalgia, impaired cognition, ataxia, diarrhoea, bladder dysfunction, sweating disturbances, headaches, fever, arthralgia, skin rashes, and gastrointestinal and sleep disturbances. Excessive chemical sensitivity and odour intolerance is reported. Epidemiological analysis suggests association with pyridostigmine bromide (PB) use as nerve gas prophylaxis, insect repellent, certain vaccination regimes, a variety of possible chemical exposures and physical and psychological stress. Pituitary adenylate cyclase-activating polypeptide (PACAP), calcitonin gene-related peptide (CGRP) and vasoactive intestinal peptide (VIP) are potent vasoactive (vasodilatory) neuropeptides (VNs) having pleiotropic functions as immunomodulators, neuroregulators and hormones. VNs also have neurotrophic and anti-apoptotic roles. VNs act on G protein-coupled receptors (GPCRs) to activate adenylate cyclase, an important step in cyclic AMP metabolism. Autoimmune dysfunction of these VNs or their receptors is postulated to give rise to fatigue-related conditions such as chronic fatigue syndrome (CFS). Complex mechanisms involving heat shock proteins (hsps) and cytosine-guanine dinucleotide (CpG) DNA fragments may also be associated with autoimmunity to VNs or their GPCRs in contributing to fatigue-related conditions. Dysfunction of certain VNs may be the missing link in explaining the nebulous nexus between PB and GWS. This paper explores a possible link between exposures to PB and other chemical, physical and psychological stressors in producing a fatigue-related illness possibly related to autoimmune dysfunction of certain VNs. Treatment options involving restoration of VN function are considered in the context of analogues with other neurotransmitter fatigue-related conditions such as myasthenia gravis (MG). While evidence associating these conditions is thin, vasoactive neuropeptide neurotransmitters of the VIP/PACAP family have acetylcholine co-transmission functions via specific GPCRs. Autoimmune reactions to these receptors may have parallels with muscarinic (e.g., Sjogren's syndrome) and nicotinic (e.g., MG) acetylcholine neurotransmission. Hence theoretically, treatment options such as thymectomy, corticosteroids, plasma exchange, anti-idiotype antibodies and receptor genomic expression reactivation/suppression may be considered. Paradoxically pyridostigmine may prove to have a role in therapy although VN treatment/replacement may be associated with tachyphylaxis.

Sjogren's syndrome is an autoimmune exocrinopathy that predominantly affects salivary and lachrymal glands, leading to dry eyes and mouth. The most common clinical problems faced by the rheumatologist are those of dry eyes and mouth, parotid swelling, fatigue and extraglandular manifestations. The first stage in management is to make an accurate diagnosis based on the American/European consensus criteria. The most frequent differential diagnoses are dry eyes and mouth symptoms, a variant of chronic fatigue syndrome and fibromyalgia, and sialosis, which causes a non-inflammatory enlargement of the parotid glands. The mainstay of treatment for the sicca symptoms is local therapy, and that for the milder systemic symptoms is hydroxychloroquine. Steroids and immunosuppressive drugs are reserved for more severe extraglandular disease. In spite of intensive research in other systemic treatments including biologic therapies, there is limited evidence to support their use in routine clinical practice.

Autoimmune diseases are a group of heterogeneous disorders equally characterized by the same pathogenetic mechanism: an immunological reaction against self antigens promoted by antibodies, immuno-complex formation, and self-reactive T lymphocytes. Autoimmune diseases may be separated into organ-restricted diseases and systemic ones. The damage of single organs produced by antibodies focused against specific cellular antigens characterizes the first group of diseases, whereas the latter are produced by a systemic inflammatory process initiated by inappropriate and excess immune activation that leads to immuno-complex formation and deposition onto sensitive tissues. Since connective and vascular tissue are principally damaged in these disorders, systemic autoimmune diseases are more commonly known as "connective tissue diseases" (CTD) and include: systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, Sjogren syndrome, and others. Although they are considered as different from a pathogenetic point of view, they overlap in many aspects, such as general symptoms as fever and fatigue, chronical ongoing, steroid therapy. As patients suffering from CTD are predominantly young women between the ages of 20 and 40 years, which is the period of the highest childbearing potential, particular interest must be regarded to the impact that these diseases and their therapies have on pregnancy and, conversely, the effect of pregnancy on these disorders, which may have long-lasting implications for mothers and neonates. Adverse fetal outcomes, maternal disease flares, and drug potential teratogenic risk are the main reasons why women suffering from CTD and who are pregnant or intend to become pregnant are considered a high-risk population. These patients require integrated, interdisciplinary care, addressing every aspect of rheumatology, obstetrics, and neonatology to reduce maternal, fetal, and neonatal complications.

Primary biliary cirrhosis (PBC) is a chronic and slowly progressive cholestatic liver disease of autoimmune etiology characterized by injury of the intrahepatic bile ducts that may eventually lead to liver failure. Affected individuals are usually in their fifth to seventh decades of life at time of diagnosis, and 90% are women. Annual incidence is estimated between 0.7 and 49 cases per million-population and prevalence between 6.7 and 940 cases per million-population (depending on age and sex). The majority of patients are asymptomatic at diagnosis, however, some patients present with symptoms of fatigue and/or pruritus. Patients may even present with ascites, hepatic encephalopathy and/or esophageal variceal hemorrhage. PBC is associated with other autoimmune diseases such as Sjogren's syndrome, scleroderma, Raynaud's phenomenon and CREST syndrome and is regarded as an organ specific autoimmune disease. Genetic susceptibility as a predisposing factor for PBC has been suggested. Environmental factors may have potential causative role (infection, chemicals, smoking). Diagnosis is based on a combination of clinical features, abnormal liver biochemical pattern in a cholestatic picture persisting for more than six months and presence of detectable antimitochondrial antibodies (AMA) in serum. All AMA negative patients with cholestatic liver disease should be carefully evaluated with cholangiography and liver biopsy. Ursodeoxycholic acid (UDCA) is the only currently known medication that can slow the disease progression. Patients, particularly those who start UDCA treatment at early-stage disease and who respond in terms of improvement of the liver biochemistry, have a good prognosis. Liver transplantation is usually an option for patients with liver failure and the outcome is 70% survival at 7 years. Recently, animal models have been discovered that may provide a new insight into the pathogenesis of this disease and facilitate appreciation for novel treatment in PBC.
