The authors report two cases of the Shulman's syndrome. Twenty one cases of this new entity are found in the literature. The main signs are the acute painful onset after an unusual physical exertion, the development of fasciitis, and (or) myositis, and (or) scleroderma of limbs, the absence of Raynaud's phenomenon, visceral involvement, constant eosinophilia and hypergammaglobulinemia; the prognosis is good with an improvement sometimes spontaneous or coincident with prednisone therapy. One of the observations is interesting by the association with Gougerot-Sjogren's syndrome, and a familial case of morphea. The prognosis in this case is mediocre: failure of corticotherapy, and incomplete remission with cyclophosphamide.

We reported 9 cases of primary Sjogren syndrome (SS) who were complicated with nervous system involvement. All were women. Age between 24 to 58 years old. Their clinical symptoms of the nervous system varied widely, 7 of them manifested with the involvement of central nervous system, the main features were in case 1 bouts of seizures, case 2 multi-level damage of the brain and spinal cord which was similar to multiple sclerosis, case 3 recurrent hemiplegia caused by cerebral thrombosis then fatal vascular hemorrhage, case 4 sudden hemiplegia, case 5 persistent psychological disturbance, case 6 cranial neuropathy of V and VII, case 9 multi-focal symptoms of ataxia, myelopathy and transient blindness. 5 of the 9, case 3, 6-9 all appeared with the symptoms of peripheral neuropathy, case 7 also complicated with carpal tunnel syndrome. 4 of the 9 cases also complicated with renal tubular acidosis and/or chronic active hepatitis and/or fibrosing alveolitis and/or thrombocytopenic purpura and/or myositis. No differences of the positivity of autoantibodies was observed between those with or without nervous system involvement.

The convergence of studies in the clinical and basic sciences has resulted in the definitive identification of many intracellular antigens which are the targets of autoantibodies in patients with systemic lupus erythematosus, scleroderma, dermatomyositis/polymyositis, Sjogren's syndrome, mixed connective tissue disease, and drug-induced autoimmunity. Some of this new knowledge includes the identification of the Sm and RNP antigens as ribonucleoprotein particles involved in splicing of precursor messenger RNA, Scl-70 as DNA topoisomerase I, proliferating cell nuclear antigen as auxiliary protein of DNA polymerase delta, and certain antigens in myositis as aminoacyl transfer RNA synthetases. This information confirms, at a molecular level, the presence of specific profiles of autoimmune responses so that autoantibodies can be used in clinical medicine as diagnostically useful immune markers. In addition the data give compelling reasons to consider that certain autoimmune diseases are antigen-driven. Many auto-antibodies have the interesting feature of recognizing epitopes on the antigens which are active or functional sites of the molecule. It is suggested that the data provide clues to the nature of the intracellular particle initiating the immune response and may help to elucidate some of the early mechanisms of the autoimmune process.

Using ELISA on fixed endothelial hybridoma (EAhy.926) cells we investigated the occurrence of antiendothelial antibodies (AEA) in the sera from patients with scleroderma systematica (SS) (n = 70) and Raynaud's disease (RD) (n = 19). The mean IgG and IgA-AEA levels were significantly higher in the SS patients than RD patients (p < 0.001) and controls (p < 0.001). We have detected circulating IgG-AEA in 64.2% of patients with SS, 35.2% of SS sera were positive for IgA-AEA. In patients with RD, the frequency of AEA corresponded to that of the random population sample. We have found a high incidence of Raynaud's phenomenon, myositis, telangiectasia and marked digital ischaemia (digital ischemic pulp ulcers, digital scars, osteolysis and autoamputation) among AEA positive patients with SS. AEA-positive patients were characterized by high extent and severity of Raynaud's phenomenon and higher average nailfold capillary microscopy scores. No correlations were found between AEA and different clinical or laboratory parameters, including the type of scleroderma (diffuse and limited), the presence of anti-Scl-7O and anticentromere antibodies and the clinical features of SS (lungs, kidneys and heart involvement, esophageal dysfunction, calcinosis, Sjogren's syndrome). There was no significant correlation between the AEA level and patient age, extent of skin involvement (skin score). Thus, in SS, AEA is associated with a peripheral vasculopathy and represent a useful marker for the diagnosis of endothelial dysfunction.

In a young male chronic generalized HBV infection (acute viral hepatitis in childhood, HBsAg, HBeAb, HBcAb in the blood serum) ran with a long-term fever and involvement of many organs and systems (the liver, lungs, CNS) complicating the diagnosis. The patient died in the presence of CNS affection and hepatorenal insufficiency. At biopsy and autopsy it was established that the patient had active hepatic cirrhosis, fibrosing alveolitis, pulmonary vasculitides, chronic pneumonia, cerebral vasculitis, myocarditis and postmyocarditis cardiosclerosis, necrotizing myositis, Sjogren's syndrome, mesangioproliferative glomerulonephritis.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the presence of antinuclear antibodies. We performed serological analysis of cDNA expression library (SEREX) to identify autoantibodies associated with SLE. The screening of three different cDNA expression libraries with pooled sera of patients with SLE yielded 11 independent clones that reacted with pooled sera of patients with SLE. In this screening, autoantibodies to poly(ADP-ribose) polymerase (PARP), U1snRNP, and galectin-3 were prevalent in the sera of patients with SLE (26/68, 25/68, 12/63, respectively). The frequency of autoantibody to PARP was significantly higher in SLE than that of healthy donors (0/76) (38.2% vs 0%, p<0.00001). The autoantibody to PARP was infrequently detected in the serum of patients with RA (1/50). However, autoantibody to PARP was not found in the sera of patients with other rheumatic diseases including Sjogren's syndrome (0/19), systemic sclerosis (0/18), and polymyositis/myositis (0/37). The frequency of autoantibody to human galectin-3 (12/63) was significantly higher in SLE than that of healthy donors (0/56) (19% vs 0%, p=0.0006). Autoantibody to galectin-3 was not found in the sera of patients with rheumatoid arthritis (0/50), Sjogren's syndrome (0/18), and systemic sclerosis (0/19). Interestingly, autoantibody to galectin-3 was also prevalent in the sera of patients with polymyositis/dermatomyositis (16/37, 43.2%). Further functional characterization of these autoantibodies would be necessary to determine their value as diagnostic markers or to define clinical subsets of patients with SLE. Statistical analysis revealed that the presence of autoantibody to PARP was inversely related with pleurisy, and the presence of autoantibody to galectin-3 related with renal disease.

Scleroderma can be accompanied by arthralgias, inflammatory arthritis, flexion contractures, nerve entrapment, myositis, or myopathy. Antibodies in scleroderma can occur in other connective tissue diseases; overlap syndromes between scleroderma and Sjogren's syndrome, lupus, and rheumatoid arthritis are reported. Many of the musculoskeletal symptoms in scleroderma are treated symptomatically; most treatments are not proven in randomized controlled trials in these patients. Musculoskeletal manifestations are a major cause of morbidity and disability in scleroderma.

Several extrahepatic manifestations have been associated with infection with Hepatitis C virus (HCV) infection. It has been associated with Sjogren's syndrome (SS) and inflammatory myositis (IM). The objective was to look at the prevalence of anti-HCV antibodies in the serum of SS and IM patients of Indian origin. Individuals satisfying the European Economic Community criteria for the diagnosis of SS and those satisfying the criteria of Bohan and Peter for the diagnosis of IM were recruited in the study. Routine evaluation for liver functions was made. Anti-HCV antibodies were tested by a third generation ELISA, using microplate HCV3.0 ELISA. Of the 23 patients with SS studied, 14 had extraglandular features. The commonest were anaemia and arthritis in six each, followed by in lymphopenia in two. One patient each had interstitial lung disease, hypothyroidism and chronic active hepatitis. Twenty-two patients with IM were studied alongside. None of the patients had abnormal liver functions. One patient with primary SS tested positive for anti-HCV antibodies. None of the patients with inflammatory myositis tested positive for anti-HCV antibodies. The presence of anti-HCV antibodies in our cohort of patients with SS and IM is low and more in keeping with the generally low prevalence of the infection in the Indian population.

Shrinking lung syndrome (SLS) is a rare complication of systemic lupus erythematosus (SLE) characterized by unexplained dyspnea, a restrictive pattern on pulmonary function tests, and an elevated hemidiaphragm. A total of 59 cases are reported in literature including the current case. The mean age of these patients is 36.85 years (range, 15-61 years), and the female-to-male ratio is 6:1. This disorder is seen primarily during the later stages of SLE. The most common presenting features include dyspnea and pleuritic chest pain. Myositis has been reported in only 8 of 59 patients (13%). Diagnosis is made with chest x-ray showing an elevated hemidiaphragm and a restrictive pattern on pulmonary function testing without any evidence of interstitial lung disease along with decreased transdiaphragmatic pressure (Pdi). Corticosteroids are the most common method of treatment. Immunosuppressive therapy, beta-agonists, and theophylline are used in those resistant to steroids. The prognosis is generally good. This article reports the case of a 22-year-old man presenting with a 7-month history of dry mouth and dry eyes accompanied by increasing difficulty in breathing, progressing to dyspnea at rest. The patient's history included bilateral parotid gland swelling and nephrotic syndrome diagnosed 4 years earlier. Pertinent physical and laboratory findings included positive Schirmer's test results; bilateral parotid gland enlargement; bibasilar lung crackles; synovitis of the second and third proximal interphalangeal joints; a positive antinuclear antibody (Ro/SSA), Sm, and anticardiolipin antibodies; and elevated right hemidiaphragm on chest x-ray. Pulmonary function tests demonstrated restrictive lung disease with normal high-resolution computerized axial tomography. A dramatic response to oral prednisone (60 mg daily) was observed in all of the patient's complaints in a matter of several days. A diagnosis of SLE with secondary Sjogren's syndrome (SS) and SLS was made. Although SLS has been reported in association with SLE, there has been only one previous report of SLS in SLE/SS overlap syndrome. Early recognition with appropriate treatment can decrease the morbidity associated with this rare syndrome.

In dermatomyositis (DM) there is strong histopathological evidence of a microvascular pathogenesis, including endothelial microtubular inclusions. In nonspecific myositis, perimysial and perivascular infiltrates in the muscle biopsy similar to DM are found. Microtubular inclusions in endothelial cells were systematically searched for and found in 4 of the 20 muscle biopsies of nonspecific myositis patients (20%). Three had a CTD (SLE, scleroderma, and Sjogren syndrome). Ten patients with DM and 5 patients with sporadic inclusion body myositis served as positive and negative controls, respectively.
