A possible link is suggested between hepatic diseases and rheumatic disease. Polyarthralgia and polyarthritis may be seen during the prodromal period of acute viral hepatitis, especially in hepatitis B virus (HBV). The symptoms of arthritis, mild, localized or generalized, mostly involve the small joints of hands. Joint symptoms frequently precede the onset of jaundice, no residual joint deformities. Circulating immune complexes are believed to play a causative role in the development of vasculitis and arthritis. Hemochromatosis is an antosomal recessive disorder of iron. About 43%-81% of patients with hemochromatosis have arthritis. The common extrahepatic manifestations of autoimmune hepatitis are arthralgia and skin rash. The reported prevalence of symptomatic inflammatory arthropathy in patients with primary biliary cirrhosis ranges from 4% to 50%. Skeletal involvement with Wilson's disease is common. Such patients may complain of pain and stiffness, mainly in the knee, wrist, or other large joints. Shwachman's syndrome is a disorder of pancreatic exocrine. Symmetric bone lesions have been reported in 10% to 15% of patients. They are involved predominantly at the femoral neck. Rheumatic symptoms are seen in one third of adult patients with cystic fibrosis and arthritis in 2.5% to 12% of patients. The arthritis caused by pancreatic panniculitis is usually symmetrical and involves the small joints of the hand, wrist, and feet, but may involve such larger joints as the elbow, ankle, and knee.

There are multiple relations between rheumatic diseases and the liver, nevertheless the liver is extremely rare involved in rheumatic diseases. "Elevated liver enzymes" are quite often found in patients who are under the medication with immunosuppressive drugs or/and non-steroidal antirheumatics. The most frequent cause for "elevated liver enzymes" are toxic and allergic side effects of drugs; however, in rare cases it might be extremely helpful to examine, whether an independent liver disease exists. Underlying liver diseases which might be associated with the rheumatic disorder or exist accidentally may change the therapeutic management of the patient. If the liver disease present can cause the rheumatic disorder (e. g. virus-induced vasculitis, hemochromatosis), a specific hepatological therapy should precede the immunosuppression.

Recently, a number of medications approved for nondermatologic use have proved useful against dermatologic diseases. This article reviews the dermatologic uses and effects of deferasirox, bortezomib, dasatinib, and cyclosporine eye drops. Deferasirox--an oral iron chelator--could be an effective treatment against porphyria cutanea tarda, hemochromatosis, and pathogens such as mucor that thrive in iron rich environments. Bortezomib, a proteasome inhibitor and multiple myeloma treatment, may be effective against nodular amyloid and has been effectively used against squamous cell carcinoma; although trials demonstrate it is ineffective against metastatic melanoma. Bortezomib has many cutaneous side effects including erythematous plaques or nodules, a generalized morbilliform erythema with ulcerations and fever, purpuric eruptions, leukocytoclastic vasculitis, Sweet's syndrome, and folliculitis. Dasatinib is a multi-targeted tyrosine kinase inhibitor active in vitro against most cell lines containing BCR-ABL mutations that confer resistance to imatinib. Dasatinib is likely to be effective against dermatofibroma sarcoma protuberans and cutaneous acute lymphoblastic leukemia, and has caused panniculitis. Cyclosporine 0.05% ocular emulsion (eye drops) are approved to treat dry eyes including dry eyes caused by collagen vascular disease. Cyclosporine eye drops might also have utility in treating eye pathology of ocular rosacea, atopic keratoconjunctivitis, graft versus host disease, herpes keratitis, chronic sarcoidosis of the conjunctiva, conjunctival manifestations of actinic prurigo, keratitis of keratitis-ichthyosis deafness (KID) syndrome, and lichen planus-related kerato-conjunctivitis. This article speculates that cyclosporine eye drops would also be useful for any disease causing ectropion or eclabion of the eye as well as toxic epidermal necrolysis-related eye pathology (in particular corneal scarring).

Alpha-1-antitrypsin deficiency (AATD) is a genetic disorder that manifests as pulmonary emphysema, liver cirrhosis and, rarely, as the skin disease panniculitis, and is characterized by low serum levels of AAT, the main protease inhibitor (PI) in human serum. The prevalence in Western Europe and in the USA is estimated at approximately 1 in 2,500 and 1 : 5,000 newborns, and is highly dependent on the Scandinavian descent within the population. The most common deficiency alleles in North Europe are PI Z and PI S, and the majority of individuals with severe AATD are PI type ZZ. The clinical manifestations may widely vary between patients, ranging from asymptomatic in some to fatal liver or lung disease in others. Type ZZ and SZ AATD are risk factors for the development of respiratory symptoms (dyspnoea, coughing), early onset emphysema, and airflow obstruction early in adult life. Environmental factors such as cigarette smoking, and dust exposure are additional risk factors and have been linked to an accelerated progression of this condition. Type ZZ AATD may also lead to the development of acute or chronic liver disease in childhood or adulthood: prolonged jaundice after birth with conjugated hyperbilirubinemia and abnormal liver enzymes are characteristic clinical signs. Cirrhotic liver failure may occur around age 50. In very rare cases, necrotizing panniculitis and secondary vasculitis may occur. AATD is caused by mutations in the SERPINA1 gene encoding AAT, and is inherited as an autosomal recessive trait. The diagnosis can be established by detection of low serum levels of AAT and isoelectric focusing. Differential diagnoses should exclude bleeding disorders or jaundice, viral infection, hemochromatosis, Wilson's disease and autoimmune hepatitis. For treatment of lung disease, intravenous alpha-1-antitrypsin augmentation therapy, annual flu vaccination and a pneumococcal vaccine every 5 years are recommended. Relief of breathlessness may be obtained with long-acting bronchodilators and inhaled corticosteroids. The end-stage liver and lung disease can be treated by organ transplantation. In AATD patients with cirrhosis, prognosis is generally grave.
