Summary Aim: The cellular joint infiltrate in rheumatoid arthritis patients is rich in CD4-positive T-helper lymphocytes and macrophages, rendering anti-CD4 monoclonal antibodies (mAbs) suitable for specific immunoscintigraphy of human/ experimental arthritis. Following intravenous injection, however, mAbs are present both in the free form and bound to CD4-positive, circulating monocytes and T-cells. Thus, the present study aimed at analyzing the relative contribution of the free and the cell-bound component to the imaging of inflamed joints in experimental adjuvant arthritis (AA). Methods: AA rat peritoneal macrophages or lymph node T-cells were incubated in vitro with saturating amounts of 99mTc-anti-CD4 mAb (W3/25) and injected i.v. into rats with AA. Results: In vitro release of 99mTc-anti-CD4 mAb from the cells was limited (on average 1.57%/h for macrophages and 0.84%/h for T-cells). Following i.v. injection, whole body/joint scans and tissue measurements showed only negligible accumulation of radioactivity in inflamed ankle joints (tissue: 0.22 and 0.34% of the injected activity, respectively), whereas the radioactivity was concentrated in liver (tissue: 79% and 71%, respectively), kidney, and urinary bladder. Unlike macrophages, however, anti-CD4 mAb-coated T-cells significantly accumulated in lymphoid organs, the inflamed synovial membrane of the ankle joints, as well as in elbow and knee joints. Conclusion: While the overall contribution of cell-bound mAbs to the imaging of arthritic joints with anti-CD4 mAbs is minimal, differential accumulation of macrophages and T-cells in lymphoid organs and the inflamed synovial membrane indicates preferential migration patterns of these 2 cell populations in arthritic rats. Although only validated for 99mTc-anti-CD4 mAbs, extrapolation of the results to other anticellular mAbs with similar affinity for their antigen may be possible.

Fallot’S Tetralogy

SummaryA marked fibrinolytic activity could be demonstrated in the blood of 10 patients with polycythaemia. In these cases fibrinolysis was considered the result of a deficiency an antiplasmin. It could be demonstrated that this naturally occurring inhibitor of fibrinolysis is present in normal platelets but is lacking in the patient’s own thrombocytes. This factor is probably attached to the surface of the thrombocytes. It could be removed by repeatedly washing. Lack of antiplasmin is a dysfunction of platelets and a form of thrombopathy. It does not respond on treatment with ACA or prednisone. In primary polycythaemia busulfan (Myleran) was considered to be the treatment of choice, whereas in 1 case of secundary erythrocytosis (Fallot’s tetralogy) the reaction on unroasted peanuts was unmistakable. In 4 more patients an alcoholic extract of peanuts was given, and promising results were obtained in 3 of them. The importance of this “thrombopathic type’ of fibrinolysis has been pointed out especially in view of surgical interventions.

Recurrent Pericardial Effusion

<strong>Background:</strong> Patients with recurrent pericardial effusion and pericardial tamponade are usually treated in thoracic surgery clinics by VATS (video-assisted thoracoscopic surgery) or open pericardial window operation. The diagnostic importance of pathological evaluation of the pericardial fluid and tissue in the same patients has been reported in few studies. We reviewed pathological examination of the pericardial tissue and fluid specimens and the effect on the clinical treatment in our clinic, and compared the results with the literature. <br /><strong>Methods:</strong> We retrospectively analyzed 174 patients who underwent pericardial window operation due to pericardial tamponade or recurrent pericardial effusion. For all patients both the results of the pericardial fluid and pericardial biopsy specimen were evaluated. Clinicopathological factors were analyzed by using descriptive analysis. <br /><strong>Results:</strong> Median age was 61 (range, 20-94 years). The most common benign diagnosis was chronic inflammation (94 patients) by pericardial biopsy. History of malignancy was present in 28 patients (16.1%) and the most common disease was lung cancer (14 patients). A total of 24 patients (13.8%) could be diagnosed as having malignancy by pericardial fluid or pericardial biopsy examination. The malignancy was recognized for 12 patients who had a history of cancer; 9 of 12 with pericardial biopsy, 7 diagnosed by pericardial fluid. Twelve of 156 patients were recognized as having underlying malignancy by pericardial biopsy (n = 9) or fluid examination (n = 10), without known malignancy previously. <br /><strong>Conclusion:</strong> Recurrent pericardial effusion/pericardial tamponade are entities frequently diagnosed, and surgical interventions may be needed either for diagnosis and/or treatment, but specific etiology can rarely be obtained in spite of pathological examination of either pericardial tissue or fluid. For increasing the probability of a specific diagnosis both the pericardial fluid and the pericardial tissues have to be sent for pathologic examination.

Vein Disease

The objective: to evaluate the results of planned open surgical interventions (POSI) in pregnant women with primary symptomatic chronic vein disease (PSCVD). Materials and methods. The study included 457 pregnant women operated on a routine basis with PSCVD. The patients underwent ultrasound duplex angioscanning (USDA) of the veins of the lower extremities, inguinal canals, and iliac veins. The severity of the clinical manifestations of PSCVD was evaluated on a VCSS scale. With the help of the circadian visual-analog scale, the dynamics after the operative pain were studied. The effect of POSI on uterine tone and cardiac function of the fetus was investigated using cardiotocography. When forming the results for POSI, data from USDA, the severity of clinical and cosmetic manifestations of PCVD, the need for active prevention of thrombophlebetic, thromboembolic and hemorrhagic complications, minimization of surgical childbirth were taken into account. The results of treatment were studied in 2 groups of patients. Patients of the first group were treated with conservative therapy, the second group – POSI. Parametric indicators, which were presented as mean and standard error M(SD), were used for statistical data processing of the study, and their reliability was estimated using Student’s t-test. The species was determined to be significant at p<0.05. Results. 495 POSI were performed at 28-38 weeks gestation in an obstetric hospital (perinatal center), by a vascular surgeon from the staff of the center, who was familiarized with the peculiarities of working with this contingent of patients. Surgery was performed under local anesthesia in 346 (75.49%) pregnant women at one extremity, in 111 (24.51%) – at two in one session. According to the results of the study, it was noted that in the first group 33.7% of patients had a positive clinical result due to the reduction of pain syndrome, while 67.5% of patients had an increase and spread of varicose transformation in the area of saphenous and/or non-saphenous veins with spread of pathological venous reflux in the distal direction. 78% of patients had the need to administer prophylactic doses of low molecular weight heparins, both during pregnancy and in postpartum period. Out of 126 pregnant women with pronounced varicose veins of the external genital organs and perineum in 36 (28.6%) deliveries were performed by caesarean section. In 9 (3%) patients there was an acute thrombophlebitis of the subcutaneous veins of the lower extremities, which required 5 pregnant women to undergo urgent surgery when the inflammatory process had spread to the middle and above along the femoral vein of the large subcutaneous vein. Pregnant women of the second group with PSCVD on the basis of obstetric hospital (perinatal center) POSI were performed in the organization, which laid the ideology of the FTS program, strictly individual indications for intervention in the optimal terms of pregnancy, multidisciplinary management of patients, due to this in 93% of operated patients regression of clinical manifestations of the disease was noted, whch contributed to the correct and safe delivery of pregnancy with 100% absence of preterm birth, abnormalities in fetal development, pregnancy course, negative impact on obstetric and somatic condition of the pregnant woman. No hemorrhagic, thrombophlebic, thromboembolic complications were noted. Patients in the postoperative period did not require medical support, as during the period of pregnancy, during delivery and in the postpartum period. There were no indications for surgical delivery. 2.4% of patients experienced complications of post-operative wounds in the form of cheese, which had no effect on pregnancy and was eliminated before delivery. In the postoperative period, if necessary, it was recommended to use elastic compression class garments 1–2. Conclusion. POSI made at PSCVD in optimal terms of pregnancy in a specialized obstetric hospital by a vascular surgeon in strictly individual indications is safe, both for the fetus and the pregnant woman. It is promising to further study the results of POSI in pregnant women with PSCVD to introduce it into the arsenal of treatment of this pathology. Key words: FTS ideology, planned open surgical interventions in pregnant women.
