In sarcoidosis and other granulomatous non-caseous diseases, the election treatment is immunosuppressive, mainly with cortisones that ensure more than 70% lasting remissions. Continuous use of cortisones for a long time (8-30 months) in high doses leads to serious side effects: gastric and intestinal ulcers, obesity, osteoporosis, suprarenal dysfunction, sensitivity to infections. Good results and elimination of the important side effects were obtained by treatment with Reprimum--a semisynthetic antibiotic with a wide spectrum and immunosuppressive properties--administered alone or with prednisone in small doses (15-20 mg once) in 6 weeks' series: 2 weeks--Reprimum 10/mg/kg daily +/- prednisone and for other 4 weeks--Reprimum 15 mg/kg twice a week +/- prednisone followed by two weeks' break. In 75 patients with histopathologically confirmed sarcoidosis (of whom 7-9.3% with outside-the-lung situs, too), the treatment with Reprimum gave: 94.7% lasting remission, only 5.3% failures, reduction of the treatment period to 6-12 months and the absence of any important side reaction. In other 37 sarcoidosis cases, failures of cortisone therapy (of which 11-30% relapses after 2-6 years), the treatment with Reprimum together with prednisone allowed recovery of 29 patients (78.4%). The same treatment with Reprimum, used in 22 patients with immunosuppressive treatment indication (dermatomyositis, Kaposi's syndrome, thrombocytopenias, nodose periarteritis, silicosis), of whom 18 (81.8%) were failures of the cortisone therapy, healed 20 of these cases (90.9%). Reprimum immunosuppressive property acts at the level of T4+ lymphocyte, involved in sarcoidosis pathogenesis. The functional blockage of T4+ lymphocyte can be also achieved by cyclosporine A.(ABSTRACT TRUNCATED AT 250 WORDS)

Pemphigus vulgaris has never before been associated with silicosis, although there are many reports of silicosis accompanied by several autoimmune diseases such as progressive systemic sclerosis, systemic lupus erythematosus, dermatomyositis or rheumatoid arthritis. We observed a patient with pemphigus vulgaris accompanied with silicosis. The patient was a 75-year-old man with a 2-month history of repeated oral erosions and blisters on the back, thighs and axillas. Histological examination showed suprabasal cleavage with acantholysis. Immunoblotting analysis demonstrated binding of the patient's serum to the 130-kD pemphigus vulgaris antigen (desmoglein 3) and the 160-kD pemphigus foliaceus antigen (desmoglein 1). The patient has radiographically been diagnosed as having silicosis. An elevated serum IgG, antinuclear antibody, anti-ssDNA, antimicrosomal antibodies and a biologically false-positive reaction to the Wassermann test were also detected. Although the clinical symptoms improved after treatment with systemic steroids, the patient died due to pneumonia. This is the first reported case in which the characteristics of both pemphigus vulgaris and silicosis could be detected.

Bullous pemphigoid (BP) has never before been reported to associate with silicosis, although there are numerous reports of silicosis accompanied by different autoimmune diseases, such as systemic sclerosis, systemic lupus erythematosus, dermatomyositis or rheumatoid arthritis. We report on a 63-year-old Japanese patient with silicosis who developed tensed bullae, erosions and macular pigmentation on the trunk and extremities. Indirect immunofluorescence revealed anti-basement-membrane-zone antibodies; immunoblotting analysis demonstrated that the patient's serum reacted with the 230-kD BP antigen in the epidermal extracts, as well as a recombinant protein of the NC16a domain of 180-kD BP antigen. Clinical symptoms improved after treatment with systemic steroids. To the best of our knowledge, this is the first reported case of BP associated with silicosis.

We report on a sixty-seven year old miner with pemphigus vulgaris characterised clinically by a three month history of relapsing oral lesions and blisters/erosions on the trunk, axillae and extremities, histologically by suprabasal cleavage due to acantholysis, immunologically by the epidermal intercellular net-like pattern due to deposits of IgG- and IgM-antibodies and complement C3 in the direct immunofluorescence as well as by serum antibodies to desmoglein 3 (130 KD) and plakoglobin (85 KD) by immunoblotting analysis. Silicosis has already been known for 6 years. In addition, antinuclear antibodies, anti-ssDNA-antibodies and anti-topoisomerase antibodies were found. Clinical improvement and clearing of skin symptoms could be achieved by systemic steroids in combination with cyclophosphamide. However, the patient died of sepsis deriving from recalcitrant pneumonia. Although the association of silicosis with various autoimmune diseases such as systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis and dermatomyositis has been reported many times, our patient is, to the best of our knowledge, the second case with features of the two diseases: pemphigus vulgaris and silicosis.

Silicosis and other occupational diseases are still important even in the most developed countries. In fact, at present, silica exposure may be a risk factor for human health not only for workers but also for consumers. Furthermore, this exposure is associated with many other different disorders besides pulmonary silicosis, such as progressive systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis, glomerulonephritis and vasculitis. The relationships between these silica-related diseases need to be clarified, but pathogenic responses to silica are likely to be mediated by interaction of silica particles with the immune system, mainly by activation of macrophages. As regards renal pathology, there is no single specific clinical or laboratory finding of silica-induced nephropathy: renal involvement may occur as a toxic effect or in a context of autoimmune disease, and silica damage may act as an additive factor on an existing, well-established renal disease. An occupational history must be obtained for all renal patients, checking particularly for exposure to silica, heavy metals, and solvents.

There are few reports which describe the association of polymyositis/dermatomyositis (PM/DM) and silicosis. The purpose of this study is to describe the clinical features of PM/DM associated with silicosis. We first describe clinical features of two cases and provide a review of the literature. Finally, seven patients with PM/DM associated with silicosis are retrospectively evaluated. There were one female and six males. Histological specimens were obtained by open lung biopsy in five cases and not examined in two. The mechanism of the association between silicosis and PM/DM is discussed.
