Five children with Sharp syndrome are described presenting a non-erosive polyarthritis, hand and finger swelling, Raynaud phenomenon, myositis, dermatomyositis or SLE-like rash. Characteristic laboratory findings are, apart from elevated sedimentation rate, anemia and leucopenia, high titer IgM rheumatoid factors and antinuclear antibodies (ANA). The latter show speckled pattern, contain IgG, bind complement components and are directed against ribonuclease-sensitive nuclear antigens. All patients have antibodies against the so-called extractable nuclear antigens (Anti-ENA) and antibodies against ribonucleoproteins (Anti-RNP). Since children with Sharp syndrome rarely show renal or cerebral involvement, the prognosis seems to be fairly good.

Two patients aged 47 and 48 years respectively were found to have associated immunity disorders: myasthenia and DLE in the first case, and erythroblastic anemia, myasthenia, a lupus syndrome, and a thymoma in the second case. The association of myasthenia and DLE has been reported 39 times in the published literature (20 times only if stricter biological criteria are applied). The association does not increase the severity of the patient's condition and a thymoma is not present more frequently. Studies on the major histocompatibility complex and lymphocyte levels are still insufficient in this context: the haplotype was HLA A1 B8 in three cases out of seven. The physiopathological data available cannot confirm the possibility of a common pathogenesis in which the thymus and lymphocytes could play a determining role.

Antibodies to histones were investigated in the serum of forty-five patients with spontaneously occurring systemic lupus erythematosus (SLE) who were not receiving any form of treatment. Twenty-three had active and twenty-two had inactive disease. Thos with active disease were also studied after the initiation of corticosteroid treatment to determine the effect of treatment on anti-histone antibodies. Both a complement fixation method and indirect immunofluorescence of acid-eluted histone-reconstituted tissue sections were used, with excellent correlation between these two methods. Eleven of the forty-five SLE patients, but none of forty-five normal controls had antibodies to histone. Untreated patients with active and inactive disease had a similar incidence of antibodies to histone. They disappeared, however, soon after the initiation of treatment in the patients with active disease. Patients with antibodies to histones had a higher prevalence of cutaneous vasculitis, anaemia, lupus nephropathy and Raynaud's phenomenon, but a lower prevalence of lupus brain involvement than those without such antibodies. Only the latter, however, reached statistical significance.

The 25,000 dalton protein of Mason-Pfizer monkey virus (MPMV) was isolated by gel filtration chromatography. In agreement with results from other laboratories, antisera to type-C and the non-type-C bovine leukemia and equine infectious anemia viruses did not precipitate 125I-labelled MPMV p25. In addition, these viruses did not cross-react in a competition radioimmunoassay for MPMV p25. Twenty-one human tissues (15 breast carcinomas, 2 normal breasts, 3 acute myelogenous leukemias and 1 sarcoma) were fractionated by detergent solubilization, ammonium sulfate precipitation, and DE-52 anion exchange chromatography. These methods were shown to be highly effective for purification of MPMV p25. Under assay conditions which minimized incubation damage to the 125I-MPMV p25, all tissues failed to react in the competition radioimmunoassay (RIAT). Two hundred and two human sera or plasma specimens, including those from patients with breast cancer and 33 age-matched controls, from 50 patients with hematologic malignancies, from 12 patients with amyotrophic lateral sclerosis, and from 14 patients with systemic lupus erythematosis, were examined for antibodies to MPMV p25. With the exception of two multiple myeloma plasma which produced artifactual false positive reactions based on hypergammaglobulinemia, a known complication of salt precipitation radioimmunoassays, the remainder of the specimens were negative for evidence of MPMV p25 antibodies.

Glomerulonephritis constitutes an important category of renal diseases in animals and has been recognized with increasing frequency in the last decade. We report here the comparative morphologic aspects of glomerulonephritis as a naturally occurring disease of animals. We briefly review the immunopathogenesis of glomerulonephritis. The morphology of renal lesions occurring in glomerulonephritis in dogs, cats, cattle, sheep, horses and swine has been reviewed with emphasis on the range and specificity of various glomerular lesions and on the comparison of lesions between various species. A distinction was made between glomerulonephritis as a primary disease entity and glomerulonephritis associated with other disease processes. Primary idiopathic glomerulonephritis occurred in all species but was most commonly recognized as a clinically important disease in dogs and cats. Glomerulonephritis also occurred in association with other diseases such as equine infectious anemia, chronic hog cholera, canine pyometra, dirofilariasis, feline leukemia virus infection and canine systemic lupus erythematosus.

A diagnosis of systemic lupus erythematosus (SLE) was established in a 54-year-old woman with a compatible history, as well as patchy alopecia, anemia, arthralgias, and a positive LE cell preparation. Sixteen months later bilateral hilar and mediastinal lymph nodes appeared on chest roentgenogram. Sarcoidosis was diagnosed when hypercalcemia and noninfectious, noncaseating epithelioid granulomas were found in the skin and liver. The sarcoidosis remitted with corticosteroid therapy, but slowly advancing renal failure ultimately resulted in the patient's death. We believe the concurrence of SLE and sarcoidosis had not been previously reported in the English literature. Immune mechanisms are discussed.

The infant of a mother with systemic lupus erythematosus (SLE) developed an extensive cutaneous eruption at 5 weeks of age. Biopsy findings were consistent with cutaneous lupus erythematosus (LE). Splenomegaly, anemia, neutropenia, and depressed total hemolytic complemtnt levels were additional findings. The course was benign, and all manifestations disappeared by 4 months of age. Fifty-two previously reported infants with cutaneous lesions, congenital atrioventricular heart block, or hematologic manifestations of neonatal LE are reviewed.

Bacterial endocarditis is an elusive disease that challenges clinicians' diagnostic capabilities. Because it can present with various combinations of extravalvular signs and symptoms, the underlying primary disease can go unnoticed.A review of the various extracardiac manifestations of bacterial endocarditis suggests three main patterns by which the valvular infection can be obscured. (1) A major clinical event may be so dramatic that subtle evidence of endocarditis is overlooked. The rupture of a mycotic aneurysm may simulate a subarachnoid hemorrhage from a congenital aneurysm. (2) The symptoms of bacterial endocarditis may be constitutional complaints easily attributable to a routine, trivial illness. Symptoms of low-grade fever, myalgias, back pain and anorexia may mimic a viral syndrome. (3) Endocarditis poses a difficult diagnostic dilemma when it generates constellations of findings that are classic for other disorders. Complaints of arthritis and arthralgias accompanied by hematuria and antinuclear antibody may suggest systemic lupus erythematosus; a renal biopsy study showing diffuse proliferative glomerulonephritis may support this diagnosis. The combination of fever, petechiae, altered mental status, thrombocytopenia, azotemia and anemia may promote the diagnosis of thrombotic thrombocytopenic purpura. When the protean guises of bacterial endocarditis create these clinical difficulties, errors in diagnosis occur and appropriate therapy is delayed. Keen awareness of the varied disease presentations will improve success in managing endocarditis by fostering rapid diagnosis and prompt therapy.

Administration of oral ferrous salts is the preferred method of treatment for anemia due to iron deficiency. However, in certain clinical situations, the response to oral therapy may be suboptimal. Parenteral iron therapy is effective in these instances and may produce a faster response than the oral route.Of 30 patients treated by total dose intravenous infusion of iron-dextran, a prompt reticulocytosis occurred in all patients except one case associated with systemic lupus erythematosus. Hematologic improvement in this case followed remission of the systemic lupus erythematosus. Hematologic response was complete in 18 patients in five to nine weeks, but could not be evaluated in 11 cases because of recurrent bleeding. There were two adverse reactions: generalized pruritus after injection in one patient, and superficial thrombophlebitis at the injection site of another.The response to therapy in iron deficient anemia is dependent on bone marrow capacity, the severity of the anemia, and the availability of iron. Response was fastest in those who had been severely anemic for prolonged periods of time. Total dose infusion with iron-dextran is a safe and effective treatment for iron deficient anemia in selected cases. Initial response appears to be faster than that on oral therapy with the exception of those with a mild degree of anemia.

The coexistence of organ-specific and nonorgan-specific autoimmune diseases is an interesting phenomenon. A 52-year-old woman was admitted with fever, general discomfort, polyarthritis, and Raynaud's phenomenon. Physical examination revealed a goiter of stony consistency, hardening, paleness, and atrophy of the skin on the face and upper limbs, and blood hypertension (180/110 mmHg). The biological data included leukopenia, moderate anemia, and a very high sedimentation rate. The latex test was positive (+++); LE cells positive (+); hypergammaglobulinemia (3.5 g); antinuclear antibodies, 1/1280 with an immunofluorescence granular pattern; antithyroid antibodies, 1/160. There was pulmonary, renal, and gastrointestinal involvement compatible with scleroderma, which was confirmed by skin biopsy. A thyroidectomy revealed the existence of a papillary carcinoma with thyroiditis. Responde to treatment with immunosuppressive agents, hypotensive drugs, and thyroid substitution therapy was initially good. The patient was readmitted 8 months later with general discomfort and a severe hyperproteinemia (10 g/100 ml), including 65 percent gammaglobulin and requiring various sessions of plasmapheresis. The patient was discharged, but died suddenly 4 months later. The association of lupus and scleroderma in this patient is discussed and the possibility of its being a mixed connective tissue disease is discarded. The association of this condition with Hashimoto's thyroiditis, and the latter with papillary carcinoma of the thyroid are analyzed. The peculiar features of this case are pointed out. The authors postulate that the cause of the sudden death was a vascular cerebral complication induced by the extreme hyperproteinemia.
