Syndrome of Inappropriate Secretion of Antidiuretic Hormone Cholestasis and Pericardial Effusion Due to Brucellosis Infection: A Case Report

Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is an extremely rare complication of infectious diseases. A rare case of brucellosis complicated by syndrome of inappropriate secretion of antidiuretic hormone (SIADH) cholestasis and pericardial involvement is reported. A 27-year-old woman was admitted for fever, abdominal pain, and scleral icterus. Her medical history revealed no recent use of diuretic agents. In addition to cholestasis and elevated liver enzymes, euvolemic hyponatremia, hypouricemia, low plasma osmolality, and high urinary osmolality were also detected. Surrenal and thyroid tests were also within normal range. Echocardiography revealed minimal pericardial effusion with normal cardiac functions. The final diagnosis was SIADH due to Brucellosis. Hyponatremia, cholestasis, and pericardial disease were resolved with effective antibrucellar treatment with streptomycine and doxycycline. After completing treatment of brucellosis, there was not any more evidence of cholestasis and pericardial fluid

Matrix Metalloproteinases in Pathogenesis of Hemorrhoidal Disease

The aim of this study is to investigate the accuracy of serum matrix metalloproteinase (MMP) levels in an effort to find a reliable factor that may play an important role in pathogenesis of hemorrhoidal disease. Twenty control subjects and 21 Grade I, 19 Grade II, 20 Grade III, and 21 Grade IV patients with internal hemorrhoid were included in this prospective study. The mean ages of control subjects were 47.65 +/- 6.71 standard deviation (SD) years (range, 37 to 60 years). The mean age of internal Grade I, Grade II, Grade III, and Grade IV patients with internal hemorrhoid were 48.85 +/- 6.44, 47.20 +/- 6.75, 44.90 +/- 6.13, and 42.95 +/- 3.49 SD years (ranges, 38 to 58, 38 to 60, 34 to 55, and 38 to 50 years), respectively. Ten milliliters of blood was taken from all subjects. Enzymelinked immunosorbent assay (ELISA) for MMP-1, -2, -7, and -9 levels were performed using an ELISA kit (R&D Systems) following the manufacturer's instructions. There was an important difference between Grade I and Grade II groups in the serum levels of MMP-9 (P <0.01). Patients with Grade III hemorrhoidal disease had significantly higher serum levels of all MMP than patients with Grade I and Grade II hemorrhoidal disease (P < 0.001). Also, patients with Grade 4 hemorrhoidal disease had higher serum levels of MMP-7 and -9 according to Grade I, II, and III groups (P < 0.01, 0.001). High serum levels of MMP are present in patients with hemorrhoids, suggesting the possible mechanism in the pathogenesis of hemorrhoids

Increase in the circulating level of hepatocyte growth factor in pancreatic cancer patients

Objective: Hepatocyte growth factor (HGF) has been reported the cause of many biological events, including cell proliferation, invasiveness, morphogenesis, and angiogenesis. Elevated HGF content in tumor tissue was reported to predict a more aggressive biology in breast and gastric cancer patients

Serum thymidine kinase is associated with gastric adenocarcinoma

Thymidine kinase (TK) plays an essential role in the processing of thymidine within the cell and therefore it is an important marker of proliferation, particularly in tumor cells. The aim of our study was to determine the diagnostic and prognostic importance of TK measurement in gastric adenocarcinoma. The serum level of TK was measured in 72 patients with gastric adenocarcinoma. Serum levels of TK were significantly elevated in gastric adenocarcinoma in comparison with healthy individuals. Also, we have found that there are significant variations in TK serum concentrations when measured that correlate with important variations in clinico-pathological features and prognostic significance (Tab. 2, Ref. 16).

Preoperative Serum Levels of Mesothelin in Patients with Colon Cancer

Background. Screening for biochemical markers is important for diagnosing colon cancer. In this study, the reliability of serum mesothelin levels as a potential diagnostic and screening instrument was evaluated concerning colon cancer. Methods. Ninety-five patients who had undergone colonoscopic examination and who were diagnosed with colon cancer were included in the study. The serum mesothelin levels were measured with the ELISA kits and were evaluated in terms of significant difference when compared between colon cancer and control group. Results. Patients with colon cancer had significantly higher mesothelin serum levels (P<0.001) than the control groups. We found significant associations between serum levels and tumor grade, perineural invasion, and vascular invasion (resp., P<0.001). Conclusion. Evaluating the serum levels of mesothelin has a potential to detect and screen the colon cancer in affected patients. Our data suggest that mesothelin exhibits effects towards colon cancer and serves as a biomarker for this deadly disease

Lipid Peroxidation and Transforming Growth Factor 1 Levels In Gastric Cancer at Pathologic Stages

OBJECTIVE: High levels of TGF-β1 and enhanced TGF-β1 receptor signaling are related to the pathology of gastric cancer. This effect is caused by oxidative stress and lipid peroxidation products. The aim of this study was to investigate the levels of TGF-β1 and lipid peroxidation products in gastric cancer patients and their correlation with pathologic stage. MATERIAL AND METHODS: Lipid peroxidation products and TGF-β1 levels were studied in the serum samples of 50 gastric cancer patients and 18 control subjects. RESULTS: HNE-protein adducts and TGF-β1 levels were significantly higher in T2, T3 and T4 gastric cancers than in either the T1 stage or controls (p<0.001). Pathologic stage was correlated with TGF-β1 levels (r=0.702, p<0.05). CONCLUSION: These markers production may contribute to tumor angiogenesis and aid in the prognosis of the gastric cancer

Human neutrophil peptides 1, 2 and 3 (HNP 1-3): elevated serum levels in colorectal cancer and novel marker of lymphatic and hepatic metastasis

Objective. Biological levels of localized colon tumors are needed for the diagnosis and prevention of colon cancer. Numerous biomarker studies are produced currently through research. We investigated some peptides with the aim of identifying biomarkers for colorectal cancer and lymphatic and hepatic metastasis. Materials and methods. A total of 100 patients with histologically proven colorectal cancer and 60 normal volunteers were included in this study. Preoperative serum was collected for analysis. Human neutrophil peptides levels (HNP) were assayed by solid phase RIA (Radio Immun Assay) based on monoclonal antibodies. Results. The HNP-1, -2 and -3-also known as alpha-defensin-1, -2 and -3-are present in elevated concentrations in the plasma from colorectal cancer patients. Conclusion. Preoperative high plasma HNP 1-3 levels are associated with colorectal cancer. The HNP 1-3 levels may procure information on patients with lymph node or hepatic metastasis
