Addison's disease is an uncommon endocrine condition manifested by a variety of nonspecific symptoms, such as malaise, anorexia and nausea. Symptoms usually do not occur until most of the adrenal gland has been destroyed. Autoimmune disease has surpassed tuberculosis as the primary cause of Addison's disease. Nevertheless, tuberculosis still accounts for a significant proportion of cases. The rapid adrenocorticotropic hormone (ACTH) stimulation test is useful for identifying adrenal insufficiency. Maintenance therapy consists of hydrocortisone and fludrocortisone.

An adult horse with a 2-month history of anorexia, ataxia, and oral blisters had developed these clinical signs just prior to the appearance and growth of a cervical mass. Bullous stomatitis was characterized histologically as subepidermal clefting. Clinical signs were unresponsive to treatment with antibiotics or corticosteroids; however, surgical removal of the mass coincided with remission of all signs. Histologic findings of the mass were consistent with hemangiosarcoma. Results of indirect immunofluorescence and immunoprecipitation on frozen serum from the horse were characteristic of paraneoplastic pemphigus in human beings, a newly recognized mucocutaneous autoimmune disease associated with neoplasia.

Interferon treatment means for many patients prolongation of their life. On the other hand, this treatment is associated with many undesirable effects listed below. Symptoms reminding of influenza (fever, articular and muscle pain, fatigue, loss of appetite, gastrointestinal complaints and mild psychic irritability) are frequent. As regards laboratory examinations, interferon alpha treatment is associated with a drop of the number of leucocytes and to a smaller extent also other blood elements and with a rise of liver enzyme levels. Serious and life threatening undesirable effects are fortunately rare. In rare instances cardiovascular complications were observed (impaired rhythm, drop of blood pressure) and sometimes interferon treatment was suspected to be associated with myocardial infarction. Interferon alpha can cause deterioration of already existing autoimmune disease or cause renal failure. In rare instances psychoses induced by interferon alpha were described as well as central and peripheral neurological disorders. As the number of patients treated with interferon alpha is increasing, all doctors treating these patients should know its undesirable effects.

Acute adrenal insufficiency is a rare disorder associated with high morbidity and mortality if allowed to progress unrecognized. A constellation of nonspecific symptoms including weakness, easy fatigue, nausea, anorexia, and weight loss are typical features of adrenal insufficiency. The index of suspicion should be particularly high if the patient has hyperpigmentation; hyponatremia and/or hyperkalemia; a history of autoimmune disease (hypothyroidism, diabetes) or recent prior use of exogenous steroids or if the patient is on anticoagulant therapy. Any decline in clinical status (hypotension, fever, decreasing mental status), especially in the setting of an acute intercurrent illness, should be treated aggressively, even before laboratory confirmation of the diagnosis. Diagnostic testing is fairly straightforward and readily available. The development of purified synthetic corticosteroid preparations has provided a safe and effective means of replacement. Early awareness, recognition, and intervention remain significant steps in altering the course of acute adrenal insufficiency.

The seminal observation that secretion of the adipocyte-derived hormone leptin was induced by inflammatory challenge has been expanded upon to demonstrate the importance of the pro-inflammatory cytokines, especially tumor necrosis factor (TNF)-alpha, in inflammatory hyperleptinemia. Initially, it was thought that cytokine-induced hyperleptinemia might somehow be involved in the anorexia and cachexia that often accompany chronic infectious, neoplastic, and autoimmune disease. While the role of leptin in disease-associated anorexia and cachexia appears tenuous in light of recent findings, there is evidence that the hyperleptinemia induced by cytokines is an integral part of the acute phase response and necessary for comprehensive immunocompetence. This hints at the existence of an integrated communication network, wherein the energy status of the animal impacts its ability to fight pathogens.

Primary care physicians have often to provide care to elderly patients presenting with non specific general complaints such as anorexia, weight loss and fatigue associated with biological inflammatory tests (increased erythrocyte sedimentation rate, increased CRP, anemia of inflammatory origin). In elderly patients, inflammatory diseases of unknown origin are most often related to an infectious illness (particularly bacterial endocarditis or tuberculosis), a systemic autoimmune disorder (temporal arteritis, polymyalgia rheumatica or ANCA positive vasculitis) or a neoplastic process. A methodological clinical approach is discussed and the most valuable complementary tests are proposed.

Retroperitoneal fibrosis is an uncommon disease, characterized by the replacement of normal retroperitoneal tissue with fibrosis and/or chronic inflammation. In two thirds of the cases retroperitoneal fibrosis is idiopathic (IRF), whereas in the remaining ones it is secondary/associated to cancer, infections, drugs, autoimmune disease and vasculitis. IRF appears as a dense, fibrous plaque that usually arises between the level of the lower aorta and the common iliac arteries. As the plaque progresses, it engulfs the adjacent structures (e. g., ureters). In its early stages IRF is characterized by a rich infiltrate of lymphocytes, plasma cells and macrophages interspersed within fibroblasts and collagen bundles. In its advanced stages it becomes relatively avascular and acellular with abundant collagen bundles and scattered calcifications. The pathogenesis is unknown: some Authors suggest that IRF is a consequence of a local autoimmune reaction against atherosclerotic plaque antigens whereas others propose that it is the manifestation of a systemic autoimmune disease. The presenting signs and symptoms are non-specific; systemic manifestations (fever, anorexia, weight loss), often associated with local symptoms, are usually found to be related to the entrapment of retroperitoneal structures. The most common local symptom is lumbar and/or abdominal pain. The treatment can be surgical and/or medical: the former is required when obstructive complications are present; the latter, associated or not with surgery, can significantly improve the outcome of IRF patients and usually modifies the natural history of the disease. Steroids and tamoxifen are the most used drugs, whereas other agents such as azathioprine, methotrexate and cyclosporine are usually given to non-responder patients.

Autoimmune hepatitis (AIH) is rare in Asian countries compared to the West, and an exceptionally low prevalence was noted previously in Taiwan. Using the revised criteria of the IAIHG, 48 cases of AIH patients were diagnosed. All patients were consecutively diagnosed over a period of 5 years. Detailed medical histories including disease onset, hepatitis B and C, alcohol, drugs, blood transfusion, and family history of autoimmune disease were recorded. Clinical manifestations, result of steroid therapy, outcome, and survival rate were investigated and analyzed. Clinical data on AIH patients with cirrhosis and without cirrhosis were compared and analyzed for their outcome. The statistical methods used were Fisher's exact test, Wilcoxon rank sum test, and Kaplan-Meier curve. Forty-eight patients were diagnosed as AIH type 1, with a median age of 58 years and a female:male ratio of 37:11. The most common clinical features at presentation were fatigue, jaundice, and anorexia. Ninety-eight percent of patients were ANA positive, and most of the patients showed elevated values of AST, ALT, serum globulin, and bilirubin. A substantial proportion of patients presented with poor liver function at entry and 35% of patients had liver cirrhosis, with relatively prolonged PT (P=0.001) and poorer outcome (P=0.005) compared to the noncirrhotics. As a whole there was a favorable treatment response and the overall survival rate was 85%. We conclude that the incidence of AIH in Taiwan is much higher than previously presumed and AIH type 1 is the predominant type of the disease. Although a substantial proportion of AIH patients presented with poor hepatic function at entry, as a whole there was a favorable clinical outcome.

A 62-year-old man developed a fever, fatigue, anorexia and arthralgia. Central hypocorticoidism and central hypothyroidism were observed, and a low serum antidiuretic hormon level without symptoms of diabetes insipidus, as well. Images showed swelling of pituitary stalk, mediastinal and hilar lymphnodes and pancreas, pulmonary infiltrates and retroperitoneal mass. Serum CRP level was 20.6 mg/dL, and IgG4 level was 292 mg/dL. Lung biopsy revealed pseudotumor containing IgG4-positive plasmacytes, and obliterative vasculitis both in arterioles and venules. These features were similar to those of reported IgG4-related autoimmune disease. However, replacement steroid therapy for hypocorticoidism brought about almost complete recovery except that diabetes insipidus got apparent. This is the first report on the efficacy of only a small dose of steroid, and on features of pituitary stalk involvement and central hypocorcicoidism.

Many cases of coeliac disease, a gastrointestinal autoimmune disorder caused by sensitivity to gluten, can remain in a subclinical stage or undiagnosed. In a significant proportion of cases (10-15%) gluten intolerance can be associated with central or peripheral nervous system and psychiatric disorders.A 38-year-old man was admitted as to our department an inpatient for worsening anxiety symptoms and behavioural alterations. After the addition of second generation antipsychotic to the therapeutic regimen, the patient presented neuromotor impairment with high fever, sopor, leukocytosis, raised rhabdomyolysis-related indicators. Neuroleptic malignant syndrome was strongly suspected. After worsening of his neuropsychiatric conditions, with the onset of a frontal cognitive deficit, bradykinesia and difficulty walking, dysphagia, anorexia and hypoferraemic anaemia, SPET revealed a reduction of cerebral perfusion and ENeG results were compatible with a mainly motor polyneuropathy. Extensive laboratory investigations gave positive results for anti-gliadin antibodies, and an appropriate diet led to a progressive remission of the encephalopathy.
