Pronounced antitumor effect of Thymalin in doses lower than the therapeutic doses was shown in experiments on albino outbred male rats with transplanted sarcoma 45. Tumor growth arrest and its regression were observed in more than half of animals and in other cases, the growth was suppressed by 78%. Microstructural changes in the thymus were analyzed. Significant increase in lymphoproliferative activity and the content of tissue basophils and plasmocytes in the thymus lobules was observed. Tumor regression was accompanied by the development of stable antistress adaptation reactions of calm and elevated activation...

INTRODUCTION: IgG4-related disease (IgG4-RD) is an immune- -mediated fibro-inflammatory condition with unknown etiology that can affect various organs. Although its prevalence is still unknown, it appears to be more frequent in adult males. Cardiovascular manifestations are rare and can include idiopathic retroperitoneal periaortic fibrosis, inflammatory aortic aneurism, inflammatory periarteritis and inflammatory pericarditis. Vascular involvement is a well-recognized feature and large vessel commitment, especially the aorta, can be the only manifestation of the disease...

Xanthomatous sialadenitis (XS) is rarely reported. Here we report XS in a case of HLA-B27-positive ankylosing spondylitis showing also anti-MAG-positive polyneuropathy with IgM-kappa dysimmunoglobulinemia/paraproteinemia, lung small cell carcinoma and buccal squamous cell carcinoma (SCC). The lesions were identified in submandibular and labial minor salivary glands of a neck dissection specimen (made during a buccal 1.7 cm large SCC resection procedure). The oral SCC was resected at 8 months after the diagnosis of the lung small cell carcinoma (with skull dome metastases, revealed by a superior cava syndrome) and at 2 months after radiotherapy...

Adenosine and adenosine triphosphate are involved in purinergic signaling which plays an important role in control of the immune system. Much data have been obtained regarding impact of purinergic signaling on dendritic cells, macrophages, monocytes and T lymphocytes, however less attention has been paid to purinergic regulation of B cells. This review summarizes present knowledge on ATP- and Ado-dependent signaling in B lymphocytes. Human B cells have been shown to express A1 -AR, A2A -AR, A2B -AR and A3 -AR and each subtype of P2 receptors...

Monoclonal gammopathy with renal significance (MGRS) is a relative new-described entity, diagnosed especially in older patients and deriving from the group with monoclonal gammopathy of undetermined significance (MGUS). Various renal lesions may arise in MGRS, according to the ultrastructural characteristics of the monoclonal immunoglobulin deposition in the kidney, from proliferative glomerulopathies and amyloidosis to light chain proximal tubulopathy and crystal-storing histiocytosis. Although both are considered premalign or non-malignant hematological conditions, kidney involvement in MGRS aggravates the prognosis of the patients and need to be treated aggressively...

Post-transplant lymphoproliferative disorder (PTLD) is defined as a heterogeneous group of lymphoid and plasmocytic proliferations with variable malignant potential. They often arise in immunocompromised post solid organ transplant (SOT) patients linked with Epstein-Barr virus (EBV) infection. Clinical manifestations include fever, lymphadenopathy and organ involvement. Diagnosis of PTLD requires morphopathological tissue examination. Treatment of EBV-related PTLD in SOT patients includes immunosuppressive (IS) agents' reduction, use of antiviral medication, anti-B-lymphocyte antibodies and chemotherapy for high-risk patients...

Multiple myeloma is a hematological malignancy, which sometimes creates difficulties in diagnosis, based on the presence of monoclonal protein in serum/urine and plasmocyte infiltration in the bone marrow, and on the other hand, synchronous cancers are also a diagnostic challenge. We present a case report of a patient with concurrent breast cancer and multiple myeloma. A 68-year-old woman was admitted to the hospital with diagnosis of left breast cancer in first stage of the disease. In the past, she had had several episodes of thrombocytopenia, leucocytosis, and mild anaemia, which were followed by hematologist in outpatient setting...

Sclerosing mesenteritis is a rare disease of the mesentery. Associations with surgery, trauma, autoimmunity and paraneoplastic syndrome have been suggested, but most of the cases remain idiopathic. Diagnosis is often incidental, based upon the finding of a single or multiple mesenteric lesions on abdominal CT and histopathological confirmation. Optimal treatment is still controversial, but most of the cases reported have a favourable prognosis. We present a case of a 54-year-old male with long-standing abdominal pain and nausea, whose CT revealed the presence of a large mesenteric mass...

We report the case of a 65-year-old woman who presented with a dysphonia. ENT tomography and laryngoscopy showed an endolaryngeal tumoral lesion extended to the right supraglottis. Biopsy of the lesion revealed dense lymphoid infiltrate in the lamina propria, without necrosis or ulceration of the mucosa. The infiltrate showed many CD3+, CD5+, CD4+, CD8+ lymphocytes and plasmocytes. Larger lymphoid cells with cytologic atypia expressed CD56 and cytotoxicity markers such as TIA1 and granzyme B. In situ hybridization for EBV revealed numerous positive cells...

In our opinion it is caused by incomplete awareness of the distribution of pathological process and the character of morphological changes in the patients. In this regard, we studied structural changes in the soft and bone tissue taken from various cavities of the middle ear system. Operating material was formed in paraffin after the fixation and proper processing. We proceed with decalcification of bone tissues in 15-20% nitric acid. We painted 5-6 mm thick peels prepared on the rotating microtome with hematoxylin and eosin...

Daily therapeutic plasma exchange (TPE) transformed the historically fatal prognosis of acquired, anti-ADAMTS13 antibody-mediated thrombotic thrombocytopenic purpura (TTP), leading to the current overall survival rates of >80%. However, relapses occur in up to 40% of patients and refractory disease with fatal outcomes still occurs, typically within the first days of management. In this context, the introduction of rituximab has been the second major breakthrough in TTP management. Rituximab is now routinely recommended during the acute phase, typically in patients with a suboptimal response to treatment, and increasingly as frontline therapy, with high response rates in the following weeks...

REVIEW
Siegfried Segaert, Caroline Hermans
Approximately one in four patients treated with anti-TNF agents (infliximab, etanercept, adalimumab, certolizumab, and golimumab) develops cutaneous adverse events, typically months to years after the initiation of treatment, with xerosis cutis, eczema (often psoriasiform), psoriasis, palmoplantar pustulosis, cutaneous infections, alopecia, and skin cancer being the most frequently encountered. The typical skin lesion of anti-tumor necrosis factor (TNF)-treated patients is orange-red psoriasiform eczema affecting the flexures, genitalia, scalp, or face, with high susceptibility to bacterial superinfection with Staphylococcus aureus...
