| 4209434 | Orosomucoid content of pleural and peritoneal effusions. | 1974 Jul | 22 nonneoplastic, noninflammatory effusions (cirrhosis and congestive heart failure), 12 non-neoplastic inflammatory effusions (tuberculosis, lupus erythematosus, rheumatoid arthritis, and idiopathic pleuropericarditis), and 58 neoplastic effusions (cancer of lung, breast, ovary, and pancreas, and lymphoma) were analyzed by radial immunodiffusion for orosomucoid concentration. The average concentration +/-SE was 35+/-4, 65+/-17, and 130+/-13 mg/100 ml in the three types of effusion, respectively. By gel filtration and ion exchange chromatography, orosomucoid was isolated from 12 nonmalignant and 14 malignant fluids. The orosomucoid preparations reacted as single components in acrylamide gel electrophoresis at pH 9.0, and in immunodiffusion and immunoelectrophoresis against antisera to human serum and to human plasma orosomucoid. In radial immunodiffusion, the slope of the line relating concentration to the square of the diameter of the precipitate area was identical for orosomucoid isolated from normal human plasma and from nonneoplastic effusions, but was subnormal for orosomucoid isolated from neoplastic fluids. All orosomucoid preparations had normal amino acid composition. Orosomucoid from the nonmalignant effusions had normal carbohydrate content. 11 of 14 samples of orosomucoid isolated from neoplastic fluids had abnormalities in carbohydrate composition, consisting of subnormal content of sialic acid (11 of 14), hexose (10 of 14), and hexosamine (3 of 14), and abnormally high content of hexosamine (4 of 14). Discriminant analysis showed that concentration of orosomucoid distinguished between neoplastic and nonneoplastic noninflammatory effusions more effectively than concentration of total protein, albumin, alpha(1), alpha(2), beta, or gamma-globulin. | |
| 6374900 | Immunopathologic and clinical studies in pulmonary hypertension associated with systemic l | 1984 May | PH is an uncommon manifestation of SLE. The symptoms of PH develop within a few years after the onset of the multisystem disease. The most common presenting complaints of SLE patients with PH are dyspnea on exertion, chest pain, nonproductive cough, edema, and fatigue or weakness. The important physical findings are a loud second pulmonic heart sound and a right ventricular lift. The chest roentgenogram shows a cardiomegaly, a prominent pulmonary segment, and usually clear lung fields. Pulmonary function tests may show evidence of restrictive lung disease; however, the physiologic abnormalities are mild and out of proportion to the severity of the PH. The diagnosis of PH is established by cardiac catheterization showing elevated pulmonary artery pressure, normal capillary wedge pressure, and no evidence of intracardiac or extracardiac shunts. Pathologic examination of the lung demonstrates angiomatoid lesions involving muscular pulmonary arteries. There is a thickening of the media and subintima of the arterioles. Immunoglobulin and complement deposits are found in the walls of pulmonary arteries. Immunoglobulin eluted from the lung contains rheumatoid factor and antinuclear antibody including antibody to DNA activity. DNA antigen is also present in walls of blood vessels. These results suggest an immune complex deposition process as a mechanism in the pathogenesis of PH in SLE. The clinical course of PH in SLE is variable. Symptoms may be mild and the disease follows a stable and protracted course for several years. It can, however, develop a progressive course ending in death in a few years. The clinical response of SLE patients with PH to treatment with high doses of systemic corticosteroids is not consistent or predictable. | |
| 6439969 | [Detection of autoantibodies to polymerized human serum albumin]. | 1984 Nov | Binding activity of antibodies against polymerized human serum albumin (pHSA) was measured in the serum of 348 patients with various hepatic and non-hepatic diseases and in the serum of 108 control persons. The methods used were passive hemagglutination (PH) with antigen loaded human erythrocytes and radial immunodiffusion (ID). In the PH-method only HBsAg-positive sera reacted. Blocking experiments with pHSA, polymerized bovine serum albumin (pBSA) and monomeric human serum albumin (mHSA) showed, that the PH-method measures HBsAG associated receptors for pHSA. In HBeAG-positive cases titers were significantly higher than in anti-HBe-positive sera. Using the ID-method it could be shown, that 40% of sera of patients with liver diseases (n = 272), 37% of patients with LED (n = 27), 72% of patients with rheumatoid arthritis (n = 32), 6% of patients with glomerulonephritis (n = 17) and 2% of normal persons (n = 108) reacted. These sera reacted in the immunodiffusion assay with pHSA and pBSA but not with mHSA. Autoantibodies against non species specific determinants of pHSA which are not specific for liver diseases and possibly due to disturbed immunoregulation can be demonstrated by immunodiffusion. They may possibly be modulators of the pHSA mediated binding of hepatitis B-virus to hepatocytes. | |
| 6331969 | Total care for rheumatic disorders in an integrated health care system. | 1983 Sep | Utilization of care for rheumatic disorders (chapt XIII of ICD) was studied in an area of Sweden during 1978. In the total health care system, approximately 16 to 18% of the population with a rheumatic disorder were seen. The majority (12% of the population) of these patients were treated at the primary care centres. Only 1% were registered as in-patients, 1/4 of whom were admitted to the rheumatology department. Cases with back disorders constituted the largest diagnostic group of rheumatic disorders, both in primary care and in the departments of internal medicine, at the district level as well as in the regional hospital. The most important contribution of the rheumatology department was the care of a select group of patients--those with rheumatoid arthritis and systemic rheumatic diseases. However, primary care saw more patients also within the whole group of inflammatory rheumatic diseases. In the department of orthopaedic surgery, osteoarthritis was the major diagnosis among rheumatic disorders, totalling 38% of their rheumatic in-patients. Selection of patients for specialized care depended upon diagnosis, age, sex and distance to the hospital. | |

| 7288211 | IgM antibody response to staphylococcal infection. | 1981 Oct | Of patients with staphylococcal infections, high levels of IgM antibodies of staphylococci measured by radioimmunoassay were present in 13 of 17 patients with endocarditis, nine of 23 with complicated bacteremia, one of 20 with uncomplicated bacteremia, and two of 21 with nonbacteremic infections. Of control subjects, high levels of IgM antibodies were present in seven of 26 individuals with gram-positive infections, two of 16 with gram-negative infections, two of 20 with rheumatoid arthritis, and two of 50 uninfected persons. Concomitant elevation of IgG and IgM antibody levels occurred in 20 of 40 patients with endocarditis or complicated bacteremia compared with two of 41 patients with other types of staphylococcal infections and three of 112 control subjects. IgM antibodies only were present early in the infection in six of 13 patients with staphylococcal endocarditis or complicated bacteremia. IgG or IgM antibody levels remained elevated at least four weeks after initiation of treatment. | |
| 151713 | "Tie-in" trapezium prosthesis: Long-term results. | 1978 Sep | Seventeen of 20 thumbs treated with a silicone-Dacron trapezium replacement arthroplasty for disabling rheumatoid and osteoarthritis at the base of the thumb were reviewed. Patients were uniformly satisfied with the results. Relief of pain was achieved in all but three patients. The latter required excision for tissue reaction to the implant. (Histological findings are reported in these cases.) Motion and stability were satisfactory but not normal. Postoperative subluxation occurred in six cases. Wear and bone erosion were present in two cases after operation. | |
| 166095 | Inorganic pyrophosphate pool size and turnover rate in arthritic joints. | 1975 Jun | Recent studies have shown elevated inorganic pyrophosphate (PPi) levels in most knee joint fluid supernates from patients with pseudogout (PG) or osteoarthritis (OA) and more modestly elevated levels in some supernates from patients with gout or rheumatoid arthritis (RA) relative to PPi levels found in the venous blood plasma of normal or arthritic subjects. We measured the intraarticular PPi pool and its rate of turnover to better understand the significance of the joint fluid-plasma PPi gradient. Preliminary studies in rabbits showed that (32-P)PPi passed from joint space to blood and vice versa without detectable hydrolysis. Incubation of natural or synthetic calcium pyrophosphate dihydrate (CPPD) microcrystals with synovial fluid in vitro in the presence of (32P)PPi tracer showed no change in PPi specific activity in the supernate over a 19-h period so that exchange of PPi in solution with that in CPPD microcrystals could be ignored. Clearance rates of (32P)PPi and of (33P)Pi, as determined by serially sampling the catheterized knee joints of volunteers with various types of arthritis over a 3-h period, were nearly identical. The (32P)PPi/(32P)Pi was determined in each sample. A mixture of a large excess of cold PPi did not influence the clearance rate of either nuclide. The quantity of PPi turned over per hous was calculated from the pool size as determined by isotope dilution and the turnover rate. The residual joint fluid nuclide was shown to be (32P)PPi. The PPi pool was generally smaller and the rate of turnover was greater in clinically inflamed joints. The mean plus or minus SEM pool size (mu-moles) and turnover rate (percent/hour) in PG knees was 0.23 plus or minus 0.07 and 117 plus or minus 11.9, hydrolysis rate (%/h) to Pi was 27.7 plus or minus 13.2; in OA knees: 0.45 plus or minus 0.26 and 72 plus or minus 9.2, hydrolysis 6.9 plus or minus 0.9; in gouty knees: 0.8 plus or minus 0.41 and 50 plus or minus 11.6, hydrolysis 9.8 plus or minus 2.8; and in RA knees: 0.14 plus or minus 0.14 and 114 plus or minus 35.8, hydrolysis 236 plus or minus 116. PPi turnover (mumoles/hour) correlated with the degree of OA change present in the joint as graded by radiologic criteria irrespective of the clinical diagnosis. Mean PPi turnover in joints with advanced OA was greater than in those with mild or moderate changes (P smaller than 0.001), but the mild and moderate groups showed no significant difference. We conclude that synovial PPi turnover and elevated PPi fluid concentrations are not specific for PG patients, and that these factors alone cannot be the only determinants of CPPD crystal deposition. | |
| 3857425 | Parotid hypertrophy with bulimia: a report of surgical management. | 1985 May | Benign hypertrophy of the salivary glands can occur in patients with anorexia nervosa. This enlargement has been related to nutritional deficiencies and bulimia, which is a form of episodic binge eating followed by vomiting. The surgical management of a patient with bulimia and benign bilateral parotid enlargement secondary to bulimia will be discussed. Superficial parotidectomy may be a useful adjunct in managing the cosmetic and psychological aspects of patients with anorexia nervosa and bulimia complicated by massive parotid hypertrophy intractable to medical management. | |
| 6650167 | Malignant lymphoepithelial lesion of the submandibular gland. | 1983 Sep | A case of malignant lymphoepithelial lesion affecting the submandibular gland of a 48-year-old Japanese man is described. Histologically, a well-encapsulated tumorous mass replacing almost the whole gland was composed of lymphoid and epithelial elements, and the latter revealed severe anaplasia with frequent mitotic figures indicating malignant changes. There is no sign of recurrence up to now, 32 months after the operation. Ultrastructural studies on a formalin-fixed sampling from the gland demonstrated the squamous nature of the epithelial component. This is the first case of malignant lymphoepithelial lesion of the submandibular gland detected in Japan. | |
| 7204101 | Hypergammaglobulinemic purpura and Sjögren's syndrome in a child. | 1980 Dec | Hypergammaglobulinemic purpura of Waldenström and Sjögren's syndrome are rarely reported in children. This paper reports the case of a 12-year-old girl suffering from both diseases. In the serum of this patient the presence of circulating immune complexs was demonstrated, but there was no clinical sign suggesting an immune complexe disease. After a 28-month follow-up no clinical or biological change was observed. | |
| 432890 | [Measurement by means of 99mTc-pertechnetate of the function of salivary glands before and | 1979 Mar | Judgement on xerostomia in systemic diseases of the salivary glands and on the sicca-syndrome as a side-effect of radiation therapy or of a treatment with psychopharmaca has been improved by the function test of the parotidic glands for each side individually with 99mTc-pertechnetate, particularly in view of the detection of lateral differences. Measurements of the salivation volume and activity are completive of the function test, yielding knowledge of the total excretory power of all the salivary glands. Functional remainders and reserves can be visualized objectively by additional utilization of the pilocarpine stimulation test (to-day performed with carbachol). The findings will be still more precise if the parotidic salivation is collected and measured for each side separately. This exploration method is appropriate for frequent controls in the course of a disease and for the forming of an opinion upon therapeutic effects of sialagogic agents. | |
| 752274 | [Angioimmunoblastic lymphadenopathy (AIL) rich in epithelioid cells presenting a Gougerot- | 1978 | The authors report the case of a 62-year-old woman in whom, 18 months following the development of bilateral parotid hypertrophy followed by a dry syndrome, there was the onset of an angioimmunoblastic lymphadenopathy (AIL) which consisted of the association of a multiple lymphadenopathy with a characteristic histological appearance, although poor in plasmocytes, and a febrile syndrome, but in the absence of a complete syndrom from a laboratory standpoint. This fact, incombination with the richness of the nodes in epitheloid cells, is such that this case resembles the type II "dysimmune and pseudo-lymphomatous lymphadenopathies" (DPLL) of Delsol et al. Although the term AIL has never been used before in the title of previous publications of pseudo-lymphomas occuring during Sjögren's syndrome, it would seem possible, as has already been suggested by Diebold et al. (3) with regard to several cases, that certain of these pseudo-lymphomas are true AIL. The rapidly fatal course with visceral spread shown at autopsy and above all the presence of exclusively immunoblastic plaques in several mode areas led, on the basis of the criteria of Nathwani et al. (22), to acceptance of the coexistence of an immunoblastic sarcoma. | |
| 64473 | A soluble acidic protein of the cell nucleus which reacts with serum from patients with sy | 1977 Feb | A soluble nuclear antigen that reacts with sera obtained from patients with systemic lupus erythematosus and Sjögren's syndrome has been described. The antigen, tentatively named the Ha antigen after the prototype serum, was shown to react with specific antibodies by precipitin, complement fixation, and immunofluorescence techniques. The Ha antigen prepared from isolated nuclei of calf thymus glands, calf liver, and rat liver showed identical immunological reactivities; a wide distribution among different species and tissues is presumed. The Ha antigen was destroyed by trypsin and relatively mild heat or pH variation from neutrality, but was resistant to DNase or RNase. Many of these characteristics are similar to those of the "B" antigen to which antibodies have recently been described in Sjögren's syndrome. The nuclear origin of the Ha antigen was confirmed by the speckled nuclear immunofluorescence staining pattern given by purified antibody to Ha obtained from a specific immune precipitate. Preliminary results showed approximately 13% of patients with systemic lupus erythematosus and 30% of patients with Sjögren's syndrome had precipitating antibodies to the Ha antigen. | |
| 189431 | [Pathogenic considerations in an association of systemic sclerodermia, Gougerot-Sjögren s | 1977 Jan 16 | The authors, report a case of scleroderma associated with Sjogren's syndrome and chronic active hepatitis, and propose a series of theories on the relationship between these 3 conditions. Each is successively considered as the cause of the two others through a cellular immune deficiency although the possibility of a chance association cannot be excluded. | |
| 6148050 | Salivary gamma-glutamyl transferase activity in internal diseases. | 1984 Sep | Salivary gamma-glutamyl transferase (GGT) activity was measured in 116 patients with several diseases that involved the hepatobiliary tract, pancreas, and miscellaneous disorders and in 20 normal subjects. We have found significantly elevated values of salivary GGT in cirrhosis of the liver (8.3 +/- 0.9 [mean +/- SEM] units/L), hepatic tumors (10.4 +/- 1.3 units/L), acute cholecystitis (18.3 +/- 2 units/L), acute pancreatitis (15.1 +/- 2.4 units/L), diabetic ketoacidosis (11.6 +/- 1 units/L), and Sjögren's syndrome (19.6 +/- 4.8 units/L). Salivary GGT activities were unmodified in fatty liver, infectious hepatitis, silent cholelithiasis, and mumps. Several mechanisms explain high salivary GGT activity. Measurement of salivary GGT activity in internal medicine merits further investigations to determine its potential diagnostic value. | |
| 6086552 | [Current status of serial sialography and sialoscintigraphy in the diagnosis of salivary g | 1984 May | Sialographic investigation of enlarged salivary glands contribute to the important decision whether a secretion blockage is caused by a stone, chronic inflammation, sialoadenosis, or a tumour. The results of sialographic investigations have been much improved by the method described by Brands and Schnepper (1967) of specific serial sialography using a single-shot and fast-repeating camera, under fluoroscopic control. The success rate of the sialographic diagnosis on 141 patients in the ENT Department of Saarland University Hospital was 80%. The fact that in four cases spaces, occupying lesions were falsely interpreted or undetected leads to the conclusion that where a tumour is suspected negative sialography should be followed by further diagnostic steps. Scintigraphy of the salivary glands with 4 mCi 99mTechnetium Pertechnetate produces extra information which clearly increases diagnostic accuracy. However, experience to date shows that it is not an alternative to serial sialography but rather a supporting diagnostic method. | |
| 6420361 | A case of benign lymphoepithelial lesion of the hard palate. | 1983 Oct | The benign lymphoepithelial lesion is a rare condition, most frequently affecting the parotid gland. A review of the literature brought to light 4 earlier cases with localization in the accessory salivary glands in the oral cavity. The present report presents a 5th case arising from the accessory salivary glands on the left side of the hard palate. Destruction of the underlying bone was demonstrated radiologically; the latter has not previously been described. The present report contains a survey of the literature, as well as a review of the pathogenesis, clinical aspects and treatment of the disease. | |
| 7204107 | [Changes of the lip salivary glands in glossodynia. Histologic and morphometric analysis ( | 1981 Jan | The minor salivary glands of the lower lips were analyzed histologically and morphometrically from biopsy specimens taken from 29 patients with glossodynia and 12 normal controls. The causes of glossodynia included Sjögrens syndrome [5], stomatological disorders such as diabetes mellitus, prosthesis allergy, etc. [5], psychiatric depressions [6], and idiopathic [13]. Using semi-thin tissue sections, the following results were obtained: 1. The control group had an average acinous area of 70.2%. This area was moderately reduced in the older patient. In patients with glossdynia, the acinous area was reduced to a mean value of 38.9%. Some severe cases showed values of 10% and less. 2. The area of duct structures was 9.3% in control tissues, and increased to 13.1% in patients with glossodynia. Values to 26% were rarely observed. 3. The interstitial tissue of the control group was inconspicuous and contained only few inflammatory cells. In glossodynia, the reduction of glandular acini could be positively correlated with the proliferation of the connective tissue and to stromal infiltration by lymphocytes and plasma cells. In diffuse lymphocytic sialadenitis, the mean value of the acinous area was 46%. An additional focal lymphocytic infiltration resulted in a further reduction to 27.3%. 4. The most severe cases of sialadenitis were found in glossodynia associated with Sjögren's syndrome. As such, the lip biopsy was found to be a useful method for diagnosis of the syndrome. | |
| 81178 | Human triclonal anti-IgG gammopathy. III. Determination of the clonal persistence of the I | 1978 Sep | The persistence in the structure of IgM anti-IgGs obtained from the serum of a patient (Gil) with Felty's syndrome was studied. Co-isoelectric focusing experiments showed that intact IgM from early (1970) and late (1973) sera, and their heavy and light chains had identical isoelectric points (pI). Light chains from 1970, 1973, and 1974 IgM-Gil had identical amino terminal amino acid sequences and belonged to the v Kappa II light chain subgroup. Specificity studies of IgM-Gil isolated from serum obtained in 1970, 1972 and 1974 showed identical patterns of reactivity with IgG and IgG subunits of all gamma chain subclasses. Finally, by haemagglutination-inhibition, antisera specific for idiotypic determinants of IgM-Gil-1970 were shown to be shared by IgM from 1970, 1972 and 1974 sera. The data support the notion that autoantibody-producing cell clones persist unaltered during the course of an untreated autoimmune disease, in this instance for 4 1/2 years. |
