Frequency of vitamin K oxidoreductase complex subunit-1 (VKORC1) polymorphisms and warfarin dose management in patients with venous thromboembolism

Warfarin works by inhibiting VKORC1, so polymorphisms of this gene modify the required drug dose. The aim of this study is to examine the relation between therapeutic weekly dose of warfarin and C1173T/G1639A polymorphism of VKORC1 in patients with VTE. Seventy-five patients with VTE were enrolled. Weekly warfarin doses and time (day) to reach therapeutic INR were evaluated retrospectively along with VKORC1–C1173T and G1639A alleles. The mean weekly warfarin dose was lower and time to reach therapeutic INR was shorter in homozygote alleles (AA and TT) (p  0.05). In particular, patients who need overdose of warfarin or whose bleeding score is high, study of these polymorphisms can be considered

Yüksek serum YKL-40 düzeyi akciğer kanserinde kötü prognozla ilişkilidir

High serum YKL-40 level is associated with poor prognosis in patients with lung cancer Introduction: YKL-40 is a glycoprotein that plays role in inflammation and malignant processes. High serum YKL-40 levels are associated with short survive in cancer and chronic obstructive pulmonary disease (COPD) is another reason to increase its’ level. However, limited knowledges are known in YKL-40 along with lung cancer and COPD. Materials and Methods: One hundred patients were involved to study with lung cancer (84 men, 16 women, and median age 62). Results were compared with 30 healthy volunteers. Thirteen patients were small cell lung cancer (SCLC), 87 patients were nonsmall cell lung cancer (NSCLC). 62% of patients were inoperable. results: Median YKL-40 level was 222.7 ± 114.1 ng/mL in patients and was 144.5 ± 105.7 ng/mL in controls (p 0.05). Patients with COPD had worse survive above all cut-off values (p 0.05). Özellikle 133 ng/mL‘ye göre KOAH tanılı 42 hastada KOAH olmayanlara göre yaşam süresi anlamlı derecede daha kısaydı (p= 0.01). sonuç: YKL-40 akciğer kanserinde yararlı bir belirteç ancak hücre tipi ve yaşam süresiyle ilişkisiz. KOAH’ın eşlik ettiği akciğer kanserli hastalarda ise yüksek serum düzeyleri kötü prognozla ilişkili bulunmuştur.http://tuberktoraks.or
