[Transformation of effusion and formation of granulation tissue in the pathologic process of otitis media with effusion].

OBJECTIVE: To explore the transformation of stagnant effusion (SE) and the pathologic behavior leading to granulation tissue (GT) formation in the pathologic process of otitis media with effusion (OME). METHOD: The temporoal bone slides from 306 ears with OME at the Otopathology Laboratory of the University of Minnesota USA were studied histopathologically under light microscopy. RESULT: The observations revealed a pathologic process in which the type and the condition of stagnant effusion in the middle ear cleft was variable in the dynamics of OME progression from an early pathologic stage to an advanced pathologic stage. The granulation tissue was primarily formed by two types of fibroblast proliferation in subepithelial space. The absorption and the orgnization of SE and the formation of granulation tissue maybe occur simultaneously in same areas and a same pathologic process. CONCLUSION: The granulation tissue can only form in the areas where effusion has stagnated and has been absorpted. It is very important that effusion of the otitis media should be removed completly before the formation of granulation tissue.

[The measuring of ECP and IgE in middle ear effusion of patients with otitis media of effusion].

OBJECTIVE: To study the relationship between otitis media of effusion (OME) and allergy by investigating eosinophil cationic protein in middle ear effusion ( MECP), middle ear effusion IgE (MIgE) and serum eosinophil cationic protein (SECP). METHOD: The specimens drawn from 31 patients of OME were tested with Uni-CAP-100 allergic antigen testing system for the MECP, IgE and SECP. The results then were analyzed by statistical methods. RESULT: MECP were found in all the effusion specimens of 31 patients, the average concentration of which was 56.88 microg/L. The MECP concentration level in nine specimens (28.1%) was significantly elevated. The average concentration of MIgE was 27.2 ku/L. The MIgE concentration level in three specimens (9.7%) was remarkably increased. There was a positive correlation between the MECP level and the MIgE level( P <0.05). The average concentration of SECP was 5.6 microg/L. CONCLUSION: ECP exists in the middle ear effusion of OME. OME is an allergic inflammatory process more localized in middle ear itself in some patients. There may be a complicated allergic mechanism in OME.

Serum-effusion albumin gradient in dogs with transudative abdominal effusion.

A prospective clinical study in dogs with transudative abdominal effusions examined the clinical usefulness of the serum albumin-effusion albumin (SA-EA) gradient. In humans, the SA-EA gradient facilitates classification of abdominal effusion, with a gradient > or = 1.1 indicating the presence of portal hypertension. Gradient values proved useful for predicting therapeutic response to sodium restriction and diuresis in humans. Of 49 dogs evaluated, 25 had hepatobiliary disease (group 1) and 24 had other nonhepatobiliary conditions (group 2). Portal hypertension was clinically suspected in 24 of 25 dogs in group 1 and in 15 of 24 dogs in group 2. A broad range of SA-EA gradients was found. A gradient > or = 1.1 was found in 22 of 25 (88.0%) dogs with liver disease and in 14 of 24 (58.3%) dogs with other disorders. The median SA-EA gradient was higher in group 1 than in group 2, with values of 1.4 (range, 0.7-3.1) and 1.1 (range, 0.3-2.6), respectively (P < .04). Considerable overlapping of SA-EA gradients occurred between groups and among dogs with diverse conditions such that gradient values could not distinguish dogs with hepatobiliary disease from dogs with other conditions. The overall diagnostic accuracy of the SA-EA gradient in predicting portal hypertension in dogs with and without hepatobiliary disease (69.4%) exceeded that of hypoalbuminemia (57.1%). These findings suggest that portal hypertension is a predominant force in formation of transudative abdominal effusion in dogs with hepatobiliary disease and in dogs with other disorders. Whether the SA-EA gradient can be used to guide therapeutic mobilization of effusion in dogs remains to be proved.

Lysozyme activity and immunoglobulins in middle ear effusion fluid in acute purulent otitis media and in otitis media with effusion.

147 samples of punctured middle ear effusion fluid from cases of otitis media with effusion and 150 samples from patients with acute purulent otitis media were tested for lysozyme activity. In otitis media with effusion the concentration was 182.0 U/ml, in acute otitis 433.8 U/ml. The lysozyme concentration in otitis media with effusion depended upon the nature of the effusion. Serous fluid showed an activity of 124.8 U/ml and mucoid 311.6 U/ml, respectively. In culture-positive cases of acute otitis media the lysozyme level was 423.4 U/ml. Culture-negative cases showed about the same concentration, 438.3 U/ml. The possible role of lysozyme in defence systems of the middle ear is discussed.

[Local administration of adriamycin (ADM) for malignant pleural effusion and pericardiac effusion in breast cancer].

We examined the efficacy, toxicity, and survival rate of patients treated with local administration of adriamycin (ADM) for malignant pleural effusion and pericardial effusion in breast cancer. From May 1996 to December 2002, we injected ADM into the pleural cavity for 21 courses and into the pericardial cavity for 2 courses in 18 patients. Thirteen patients showed CR (including 2 cases were injected into pericardial cavity), 2 PR, and 4 PD, and the overall response rate was 78.9%. Toxicities included nausea/vomiting, elevated fever, chest pain, and so on in 15 patients (83.3%). No severe toxicities, however, were observed. The overall survival rate after the removal of the drainage tube was 42.5% at 1 year and 16.5% at 2 years. The survival in patients with a first recurrence, and CR or PR was significantly better than other patients. We conclude that local administration of ADM is useful for treatment, without severe toxicities, of malignant pleural effusion and pericardial effusion in breast cancer.

[Cytological, biochemical and immunologic parameters of pleural effusions. Presentation of differences in relation to the nature of the effusion].

In 96 patients with pleural exudates of known origin the authors assessed different cytological, biochemical and immunological parameters in the fluid and serum. In 44 patients the pleural effusions were malignant, in 26 tuberculosis, in 17 bacterial and 9 of viral nature. Statistical analysis was carried on mean values of studied parameters. The results indicate that only bacterial effusions differ significantly from the other pleural effusions. In effusions of malignant, tuberculous and viral nature the studied parameters did not differ significantly and cannot be used as differentiating criteria.

Tuberculous pleural effusions: lymphocyte phenotypes in comparison with other lymphocyte-rich effusions.

This study investigated whether the analysis of T cell subsets and of activation markers on T cells in pleural fluids can be helpful for diagnostic purposes in tuberculous pleurisy and other lymphocyte-rich pleural effusions. Pleural effusion fluids were obtained from 18 patients with tuberculous pleurisy (TB), 21 with effusions following radiotherapy (RT) for a malignant disease, and 11 with congestive heart failure (CHF). Lymphocyte subsets were analyzed by a battery of monoclonal antibodies using an immunoperoxidase method. The majority of the lymphocytes were CD3-positive T cells (TB, 86 +/- 7% of lymphocytes; RT, 81 +/- 8%; CHF, 84 +/- 12%). The ratios of CD4-positive helper-inducer to CD8-positive suppressor-cytotoxic T cells were higher than those reported for the peripheral blood but not significantly different between the study groups (TB, 3.3 +/- 1.9; RT, 2.8 +/- 1.4; CHF, 2.5 +/- 1.1). The activation marker studies revealed that only a few pleural T cells were positive for CD38, CD25 (interleukin-2 receptor), HLA-DR antigen, and OKT9 (transferrin receptor), the proportion of CD25-positive T cells being higher in TB and in RT than in CHF and the proportion of HLA-DR-positive T cells being higher in TB than in CHF (P less than 0.05). Significant differences were not observed relative to the natural killer-cytotoxic phenotypes staining positive for Leu-7 or for CD16. Thus, we concluded that phenotypic analysis of lymphocytes is of limited diagnostic usefulness to differentiate tuberculous from other nonmalignant effusions.

Induction of inflammatory cytokines in effusion cavity by OK-432 injection therapy for patients with malignant effusion: role of interferon-gamma in enhancement of surface expression of ICAM-1 on tumor cells in vivo.

The intracavitary injection of OK-432, a streptococcal preparation, has been shown to be an effective immunotherapy for patients with malignant effusion. We found that this therapy increases surface expression of intercellular adhesion molecule-1 (ICAM-1) on tumor cells, and that the degree of increased ICAM-1 was correlated with therapeutic effects. In the present study, we investigated the ability of OK-432-induced inflammatory cytokines, such as interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1 beta (IL-1 beta), to enhance ICAM-1 expression. We treated 17 patients who had a malignant effusion with OK-432. At 24 hr after OK-432 injection, ICAM-1 levels on tumor cells were increased significantly in responders except in one case (n=9), whereas no change was evident in nonresponders except in two cases (n=8). Induced maximum levels of IFN-gamma in responders were significantly higher than those in nonresponders. In contrast, there was no significant difference in the induced TNF-alpha or IL-1 beta levels between the two groups. Two types of cultured tumor cells derived from responder patients were successfully established from the 17 different tumor cells in effusion. We performed an in vitro study using these cultured tumor cells. Treatment of the two cultured tumor cells with recombinant IFN-gamma, but not recombinant TNF-alpha or IL-1 beta, significantly increased their ICAM-1 expression to a clinically detectable level. Direct treatment of the tumor cells with cell-free effusion samples obtained from the same patients 24 hr after the therapy successfully increased ICAM-1 expression and this action was blocked completely only by a pretreatment with anti-IFN-gamma mAb. Our results suggests that in this therapy IFN-gamma plays a crucial role in enhancing ICAM-1 expression by tumor cells and that induced IFN-gamma levels may be a useful marker for evaluation of the therapeutic effect.

An immunological study of otitis media with effusion. Antibodies directed against coagulase-negative staphylococci in the effusion fluid.

From 14 chronic middle ear effusions (MEEs), 17 strains of coagulase-negative staphylococci (CS) were isolated. We then used an ELISA method to determine the antibody titers against these microorganisms in the corresponding effusion fluids and the blood sera of the patients and compared them to the antibody titers against a group of standard CS. In most cases, no specific immune response could be detected against the infecting CS in either the effusion fluids or in the sera. Our results can be explained by the inability of most CS strains to provoke a specific immune response in chronically inflamed middle ears due to their inhibition by non-specific antibodies, which reach the middle ear cavity by plasma leakage. The non-specific antibody titer against Staphylococcus hominis, however, seems to be much lower than against the other CS species. We found a high specific antibody titer against the infecting CS in the effusion fluid of a single case, but not in the serum. This finding supports the hypothesis that the middle ear mucosa has the ability to produce autonomous, local antibodies which are independent of a systemic immune response.

Therapeutic and life-prolonging effect of intrapleural injection with a streptococcal preparation, OK-432, and IL2-cultured effusion lymphocytes to breast cancer patients with malignant pleural effusion.

We developed a local AIT using PEL cultured with TCGF combined with preadministration of OK-432. Twenty-six patients of breast cancer with pleural effusion have been treated with this therapy since 1983. PEL expanded and tumor cells collapsed by day 9 in culture with TCGF. Cultured PEL possessed significantly higher cytotoxic activity against autologous tumor cells than PBL cultured in the same condition (p less than 0.05), but there was no difference between their cytotoxic activities against K562. The proliferation rate of PEL obtained after intrapleural administration of OK-432 was higher than that obtained before OK-432 (p less than 0.01). Moreover, the cytotoxic activities against both autologous tumor and K562 of cultured PEL obtained after OK-432 administration was significantly (p less than 0.05) higher than those cultured PEL obtained before. Cultured PEL (1 x 10(8)-6 x 10(9)) were transferred into the pleural cavity after the intrapleural administration of OK-432 (1-5 KE). The volume of pleural effusion increased temporarily after the administration of OK-432 but significantly (p less than 0.01) decreased after AIT. Tumor cells disappeared cytologically in 22 patients at the last puncture of pleural effusion. Pleural effusion disappeared completely in 19 of 26 patients and decreased by more than 50% in volume in 6 patients. Performance status improved in 22 patients. The response rate for OK-432-combined AIT in the present study was 96%. The survival period of the patients treated by OK-432-combined AIT in this trial was significantly (p less than 0.002) prolonged compared to that of the patients receiving chemotherapy alone.(ABSTRACT TRUNCATED AT 250 WORDS)

Role of pleural fluid C-reactive protein concentration in discriminating uncomplicated parapneumonic pleural effusions from complicated parapneumonic effusion and empyema.

The aim of this study was to determine whether pleural fluid C-reactive protein (CRP) is useful in distinguishing complicated parapneumonic pleural effusion (CPPE) and empyema from uncomplicated parapneumonic pleural effusions (UPPE). A total of 69 consecutive patients with parapneumonic effusions were enrolled in the study: 29 with UPPE, 29 with CPPE, and 11 with empyema. Concentrations of standard biochemical parameters together with CRP in the pleural fluid were measured using an immunoturbidimetric assay. Pleural CRP was significantly higher in CPPE (11.6 mg/dl) and in empyema (12.2 mg/dl) than in UPPE (3.9 mg/dl). A cutoff value of 8.7 mg/dl for pleural CRP in the diagnosis of CPPE and empyema resulted in a sensitivity, specificity, and area under the receiver-operating characteristic curve (AUC) of 0.80, 0.97 and 0.94, respectively. Traditional lactic dehydrogenase (LDH) > or = 1000 U/L and glucose < or = 60 mg/dl can differentiate CPPE and empyema from UPPE, with the sensitivity, specificity, and AUC achieving 0.75/0.60.1.00/1.00,0.95/0.22, respectively. However, for the detection of CPPE and empyema, the combination of pleural fluid CRP > or = 8.7 mg/dl and LDH > or = 1000 U/L was valuable in achieving a sensitivity, specificity, and AUC of 0.97/1,00/0.95. This study suggests that measurement of pleural CRP can be useful in the workup of patients with a parapneumonic effusion in order to differentiate CPPE from UPPE.

Proteinase activity in effusions from children with otitis media with effusion.

Proteinase activity has been demonstrated in middle ear effusions from patients suffering from otitis media with effusion. Proteinase activity was characterized by various biochemical, chemical and physical parameters. Chelators and sulfhydryl group reacting substances reduced the enzyme activity. Enzyme activity was positively correlated to the number of granulocytes present in the effusion. No correlation to bacteriological findings or to tympanic membrane status was seen and the proteinase activity showed wide ranges within different categories of middle ear effusions.

Anaplastic large cell lymphoma presenting as a pleural effusion and mimicking primary effusion lymphoma. A report of 2 cases.

BACKGROUND: Systemic anaplastic large cell lymphoma (ALCL) is predominantly a nodal disease, but extranodal involvement can occur during the disease course or as the primary presentation. We report two rare cases of ALCL presenting with a pleural effusion, mimicking primary effusion lymphoma (PEL). CASES: Two patients, a 47-year-old woman and an 81-year-old man, presented with a pleural effusion for investigation. The pleural fluid contained abundant, large, lymphoid cells with marked nuclear atypia. These neoplastic cells strongly expressed CD30 and EMA and showed a T-cell phenotype (CD3+CD45RO+ for case 1 and CD4+ for case 2). Case 1, in addition, showed ALK1 expression. The tumor cells in both cases were negative for human herpes virus type 8 (HHV8) and Epstein-Barr virus (EBV). ALCL shows overlapping cytologic features with PEL, but the T-cell phenotype, ALK1 expression in case 1, lack of association with HHV8 and EBV, HIV seronegativity and subsequent discovery of nodal disease in case 2 were all in favor of ALCL over PEL. CONCLUSION: In rare cases a pleural effusion is the presenting feature of ALCL, and distinction from PEL depends on correlation with clinical findings, detailed immunophenotyping and study of the status of HHV8 and EBV.

Secretory immunoglobulin A antibodies to respiratory viruses in middle ear effusion of chronic otitis media with effusion.

In order to obtain evidence that viral infection may be involved in chronic otitis media with effusion, an attempt was made to detect secretory IgA antibodies to respiratory viruses in the effusions. The enzyme-linked immunosorbent assay used with purified viral antigens was employed for detecting antibodies in this study. Secretory IgA antibodies against adenoviruses, respiratory syncytial, and parainfluenza type 2 viruses were demonstrated in 31 of 128 effusions (27 of 114 ears with chronic otitis media with effusions and 4 of 14 ears with blue eardrum conditions). The specificity of antibody activity to each virus was confirmed by an absorption test.

[Massive pericardial effusion in a patient with scleroderma with special reference to concentration of alpha-hANP in plasma and pericardial effusion].

A 41-year-old woman was admitted to our hospital because of scleroderma and combined valvular disease (mitral stenosis, aortic regurgitation, tricuspid regurgitation) associated with massive pericardial effusion. Plasma atrial natriuretic peptide (alpha-hANP) level was 130 pg/ml on admission, and increased temporarily with a decrease of pericardial effusion, without significant of changes of pulmonary capillary wedge pressure, pulmonary arterial pressure, right ventricular pressure nor right atrial pressure. These findings suggest that one of the mechanisms of alpha-hANP secretion, a stretch receptor mechanism, is interfered by the massive pericardial effusion. There was no relationship between atrial pressures and plasma alpha-hANP levels in this case. alpha-hANP concentration in pericardial effusion (486 pg/ml) was four to five folds higher than the plasma alpha-hANP levels.

[Diagnostic value of the tumor markers TPA-M, CYPFRA 21-1 and CEA in pleural effusion. Prospective comparison of thoracoscopic investigations in patients with pleural effusion].

The diagnostic value of tumour markers in pleural effusion is not yet clearly defined. CEA (Carcinoembryonic Antigen), CYFRA 21-1 (Cytokeratin 19-Fragment) and TPA-M, a new monoclonal-based radioimmunoassay for TPA (Tissue Polypeptide Antigen), were measured in pleural fluid and sera of 125 consecutive patients who underwent medical thoracoscopy. The group consisted of 79 patients with malignant and 45 with non-malignant pleural effusion and 1 patient without definitive diagnosis, and hence 124 patients were available for assessing the diagnostic value. In pleural fluid based on a specificity of 90% versus benign diseases the sensitivity for CEA was 52.5%; with the maximum achievable specificity of 80% for CYFRA 21-1 the sensitivity was 68% and for TPA-M with 67% the sensitivity was 67%. Based on the cut-off values for these specificities the combined use of the three tumour markers resulted in a sensitivity of 85.7% but with a lower specificity of 59.1%. There is only a limited value for tumour markers in the diagnosis of pleural effusion.

Pericardial effusion, right-sided pleural effusion and ascites associated with stage IV endometriosis. A case report.

BACKGROUND: Endometriosis has rarely been associated with ascites and less often with pleural (usually right-sided) effusion. CASE: A multiparous, reproductive-aged woman was referred for evaluation of possible ovarian carcinoma following the development of dyspnea, progressive abdominal distention, weight loss and increasing secondary dysmenorrhea. Imaging demonstrated normal ovaries in the presence of massive ascites and right-sided pleural and pericardial effusions. At laparotomy, grade IV endometriosis was noted. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and appendectomy were performed, with subsequent resolution of all cavity fluid accumulations. CONCLUSION: Pericardial and pleural effusions in the presence of ascites may be associated with endometriosis.

Antibodies specific to outer membrane antigens of Moraxella catarrhalis in sera and middle ear effusions from children with otitis media with effusion.

OBJECTIVE: Recent studies have shown that bacterial DNA is present in a significant percentage of middle ear effusions, suggesting that persistent bacterial infection may be more important in pathogenesis and recurrence of otitis media with effusion (OME) than previously considered. Although Moraxella (M.) catarrhalis is one of the most common pathogens of otitis media, relatively little is known about immune response to the organism. The objective of the present study is to investigate how systemic and local immune activities against M. catarrhalis may be associated with severity of OME. METHODS: The antibody levels specific to outer membrane antigens of M. catarrhalis in sera and middle ear effusions (MEEs) from 59 children with OME were measured by enzyme-linked immunosorbent assay. Their ages ranged from 1 to 12 years with a median 5.0 years. The children were followed 1 year prospectively and classified into two groups with or without recurrent/persistent OME according to severity of OME during the follow-up 1 year. RESULTS: Serum IgG, IgM, and IgA antibodies specific to outer membrane antigens of M. catarrhalis were detected in all samples and the median levels were 35, 0.93, and 1.2 microg/ml respectively. The MEE IgG, IgM, IgA, and secretory IgA antibodies were detected in over 95% samples tested and the median levels were 371, 158, 20, and 50 ng/mg total protein respectively. A comparison between acute and subacute/chronic phases revealed that the median levels of MEE IgG and IgM antibodies were higher at the acute phase (692 vs. 340, P = 0.06; 35 vs. 10, P = 0.02, respectively); while the MEE secretory IgA antibody level was increased at the subacute/chronic phase (74 vs. 35, P = 0.02). Either serum or MEE IgG antibody level was significantly lower in recurrent/persistent OME group than that in nonrecurrent/non-persistent OME group (13 vs. 43 ,microg/ml, P = 0.009; 238 vs. 577 ng/mg protein, P = 0.006, respectively). CONCLUSIONS: These data provide additional information on the immunologic aspects of children with OME. Decreased serum and MEE IgG antibody levels specific to outer membrane antigens of M. catarrhalis may lead to failure to eliminate this organism, resulting in persistent and/or recurrent appearance of MEE.
