Sixty six patients with non-Hodgkin's lymphomas (NHL) were studied, interleukin-6 (IL-6) was revealed in the blood sera of 33 patients. IL-6 was revealed more frequently in patients with high-grade malignant (p < 0.05) than in those with low-grade malignancy. The largest group of IL-6 positive patients included NHL patients with diffuse large B-cell lymphoma and angioimmunoblastic lymphoma. The marked relationship was found between the serum IL-6 levels and the stage of disease: the serum IL-6 level was significantly lower in untreated patients with Stages II and III disease than in those with end-stage (IV) NHL. IL-6 significantly decreased upon remission, comparable with its level before the initiation of treatment. Analysing the association of prognosis of disease with the serum IL-6 showed that in the group of patients with good (The SNLG index < 2) and intermediate (2 < SNLG index < by 2.6) prognosis, the concentration of this cytokine was significantly lower than in those with poor prognosis (SNLG index > 2.6). There was a significant decrease of the total survival rates of NHL with serum IL-6 found. Therefore, IL-6 is a good prognostic marker in NHL and associated with the activity of a malignant process. Additionally, the increased serum IL-6 levels correlated with NK activities positively and with serum IL-4 levels negatively.

James Wylie was a native of Kincardine-on-Forth and completed medical training at Edinburgh University in 1789. He emigrated to Russia in 1790 where he joined the Eletsky Regiment as a surgeon. He travelled 150,000 miles in his military medical capacity during several campaigns including the Napoleonic wars. He became the favourite of three successive Czars and made an enormous contribution to developing medical services, both military and civil being not only a notable physician and surgeon but a most effective administrator.
It was established that most patients with non-Hodgkin malignant lymphomas against the background of secondary immunodeficiency show an activation of the saprophytic bacterial and mycotic flora that results in the development of different infectious complications essentially, thus, influencing the course and prognosis of the disease. A dependence was established between the malignancy grade of non-Hodgkins lymphomas and frequency of development of non-infectious complications.
UNLABELLED: Of 105 patients with acute leukoses secondary pneumonias were found in 47.6%. A dependence was found of the frequency of pneumonia on the severity of initial hyperleukocytosis and duration of post-cytostatic agranulocytosis. The efficiency of routine criteria of diagnosis was 66% and increased significantly in microbiological and cytological investigation of the bronchoalveolar lavage fluid. TREATMENT: combined antibacterial therapy, antifungal, desintoxicating agents; in severe cases--endobronchial administration of monogroup leucocytic mass.

Based on an examination of 105 patients with cirrhosis of the liver with the syndrome of portal hypertension complicated by gastroduodenal bleedings who were subjected to splenectomy (in 86 patients there were proximal splenorenal anastomoses) the authors make a conclusion that infectious complications in the postoperative period in the group under analysis were developing against the background of the concomitant and predisposing conditions and can be compared in their incidence with infectious complications after other similar in severity operative interventions on organs of the abdominal cavity. In remote terms after operation the normalization of the indices of both cellular and humoral immunity was noted.

The data of computed tomography (CT) were used to study the semiotics of extranodal manifestations in 78 patients with varying malignancy non-Hodgkin's lymphomas. The most common lesions were found in the viscera: liver, spleen, peritoneum, omentum, pancreas, adrenals, mesentery. The CT pattern of these lesions is diverse, each site has its own specific features. Combining the clinical manifestations and CT signs of lesions to individual organs, recording the extent of lymphadenopathy will aid in establishing the diagnosis of non-Hodgkin's lymphoma. A lesion detected in some organs located both above and below the diaphragm is a typical feature of high-grade malignancy.
The potentialities of computer-aided tomography (CAT) in the diagnosis of lymphomas were studied. A total of 223 patients with disseminated lymphadenopathy were examined (78 with malignant non-Hodgkin's lymphomas, 48 with Hodgkin's disease, 54 with metastatic involvement of the lymph nodes, 18 with HIV infection, and 25 with reactive and inflammatory lymphadenopathy). CAT helped precisely assess the dissemination of the pathological process and disease stage in patients with malignant lymphomas, permitted follow up the time course of the disease, and facilitated differentiation of the condition from other diseases manifesting by disseminated lymphadenopathies.
Thirty-four primary (untreated) patients with non-Hodgkin's lymphomas (NHL) infected with Epstein-Barr virus (EBV) were examined. Their HLA phenotype and the production of interleukin-1 beta and tumor necrosis factor alpha were assessed. Serological profiles characteristic of the late stages and reactivation of EBV infection were detected in 16 (47.1%) patients. NHL of low malignancy predominated in EBV-infected patients. A greater number of blank HLA-A antigens and a higher incidence of HLA-DR7 antigen was observed in infected patients. Serum concentration of tumor necrosis factor alpha was reliably higher in them, whereas the production of this cytokine by the peripheral blood mononuclears decreased. Hence, serum tumor necrosis factor is a product of transformed B lymphocytes. Spontaneous and stimulated production of interleukin-1 beta by peripheral blood mononuclears was significantly decreased in EBV-infected patients, and the serum concentration of this cytokine similarly had a trend to decrease, which indicates an inhibition of interleukin-1 beta production in EBV-infected patients with NHL.
