Background : It is known that severe infection and inflammation lead to hemostatic abnormalities. Recently, much attention is focused on the mechanisms of infection or inflammation and on how it plays a central role in effecting the coagulation system. Disseminated intravascular coagulation in particular, is a common phenomenon in patients with sepsis, but the clinical implications of this condition are not clear. Therefore we attempted to evaluate the changes of the coagulation system in patients with sepsis and studied the factors that lead to such changes.Methods : One hundred one patients diagnosed with sepsis were enrolled in this study. The patients were clinically evaluated for underlying disease and data for inflammatory status and coagulative changes were evaluated retrospectively.Results : The WBC count increased in 76% and decreased in 6% of sepsis patients in comparison to the reference interval. The platelet count decreased in 65.3%. Changes in coagulative tests such as prothrombin time, activated partial thromboplastin time, antithrombin III, and D-dimer were observed in 70.4%, 52.7%, 87.2% and 100% of the patients, respectively. Correlation between ESR and fibrinogen was the highest in relation to the other coagulation factors. CRP also showed the highest correlation with fibrinogen in contrast to the other coagulation factors.Conclusions : This study confirmed the clear activation of coagulation in patients with sepsis. Of the evaluated factors involved in coagulation and fibrinolysis, fibrinogen showed the highest correlation to indices representing the inflammatory state. However further studies on the anticoagulant pathway are necessary in elucidating this matter. (Korean J Lab Med 2007;27:157-61)

The infections by human papillomaviruses (HPVs) are clearly associated with the subsequent development of cervical cancer. In this study, HPV genotype distribution and prevalence were detected in Korean women from January to December 2008 using PCR-DNA sequencing. A total of 2,562 cervical samples from Korean women having routine Pap smear cytology screening were used. HPV DNA was extracted from cervical swab samples and amplified by PCR in L1 region of HPV. HPV DNA was detected in 23.2% and 65.5% from the groups of normal and abnormal Pap cytology, respectively. The prevalence of high-risk types of HPV had the highest frequency in the <30 year-olds' group (50.6%). The prevalence of HPV in normal, ASCUS, LSIL and HSIL groups was 23.2%, 58.1%, 96.3% and 97.0%, respectively. Moreover, the frequencies of the high-risk types of HPV were 16.2% in the normal Pap cytology, 44.7% in the ASCUS, 76.1% in the LSIL and 94.1% in the HSIL groups. The prevalence of the high-risk types of HPV increased in proportion to the severity of the cytological classification. In the HSIL group, HPV type 16 was the most frequently found at 32.4%, followed by types 58, 53 and 33 at 17.6%, 14.7% and 11.8%, respectively. HPV type 82 was found in 5.6% of the HSIL group and was not detected in the normal Pap cytology group. The frequency of high-risk type of HPV 82 is firstly reported in Korean women. This finding could be an informative basis for the development of future HPV vaccination strategies in Korean women.
