Introduction: Sjögren’s syndrome is an autoimmune disease belonging to the group of collagenases. It is characterized by lymphocytic infiltration of the exocrine glands, leading to their impairment or complete dysfunction. The inflammatory process usually involves cells of the salivary or lacrimal glands. However, also other organs and systems can be affected. Purpose: The presentation of a Sjögren’s syndrome case. The pathologist’s role in the disease diagnosis. Case presentation: A 63-year-old female patient with the enlarged left parotid salivary gland and symptoms of xerostomia and xerophtalmia was referred for ultrasound imaging and fine-needle aspiration biopsy (FNAB). Ultrasonography revealed inhomogeneous echostructure of the salivary gland with multiple tiny, oval, hypoechoic areas, hyperechoic zones of fibrosis and enhanced vascularization of the gland. The pathological analysis of FNA showed a benign lymphoepithelial lesion, and Sjögren’s syndrome was suggested. Blood serum analysis found anti Ro-52 (SS-A), anti-La (SS-B) and anti-ANA antibodies at 1:1,000 titer. Sjögren’s syndrome was diagnosed based on accessory investigations and the clinical condition of the patient. Conclusions: The pathomorphological analysis of fine-needle aspiration biopsy of the salivary gland contributed to the diagnosis of Sjőgren’s syndrome in the patient.

Purpose: To evaluate the clinical significance of MMP-2 and TIMP-2 concentrations in the sera of patients diagnosed with colorectal cancer. Methods: The study group comprised 48 patients with colorectal carcinoma and 24 healthy controls. The serum concentration of MMP-2 and TIMP-2 proteins was evaluated by the ELISA method. Results: The mean level of MMP-2 in the sera of patients with colorectal cancer was 39.4 ng/ml and was significantly lower compared with the control (p<0.001). A decrease in TIMP-2 protein in the sera of patients with colorectal cancer was also observed where its mean level was 132.3 ng/ml. The concentration of MMP-2 and TIMP-2 did not correlated with any clinicopathological parameters, except for the patients’ age. In addition, the concentration of MMP-2 in the sera of patients with CRC correlated negatively with the number of white blood cells in the blood and the prothrombin index. The concentration of TIMP-2 correlated positively with potassium and urea concentration in the blood. Conclusions: The results of our study indicate lack of clinical usefulness of determining the levels of MMP-2 and TIMP-2 in the sera of patients with colorectal cancer. However, these proteins play an important role in the carcinogenesis of colorectal cancer.

Purpose: Growth differentiation factor-15 (GDF- 15) protein belongs to a transforming growth factor-β family which determines the growth and differentiation of cells. In cancers, GDF-15 influences on the proliferation, differentiation, viability, migration and invasiveness of cancer cells. The aim of our study was to evaluate the expression of GDF-15 in the tissue and its levels in sera of patients with colorectal cancer. Materials and methods: The level of GDF-15 in the sera of 55 patients diagnosed with colorectal cancer was determined using the ELISA method whereas expression of this protein was performed by immunohistochemical method. Results: The mean value of GDF-15 levels in the sera of patients with colorectal cancer was significantly higher than in healthy control group (p<0.001). The expression of GDF-15 in the tissue was weak, moderate and strong in 23.6%, 15.7% and 60.7% cases, respectively. Statistical analysis showed that the expression of GDF-15 correlated with patients’ age (p<0.005) and non-mucinous type of cancer (p<0.001). The high GDF-15 levels in the serum was associated with tumor size (p<0.01) and distant metastases (p<0.05). Conclusions: According to our results, we postulate that the level of GDF-15 in serum can be use to assess the metastatic behavior of colorectal cancer
