Coagulopathy parameters in patients with Crimean-Congo hemorrhagic fever and its relation with mortality.

BACKGROUND: Crimean-Congo hemorrhagic fever (CCHF) is an acute illness affecting multiple organ systems and characterized by ecchymosis, visceral bleeding, and hepatic dysfunction. In this study, we aimed to investigate the profile of coagulopathy markers (platelet count, activated partial tromboplastin time (aPTT), prothrombin time (PT), international normalized ratio (INR), fibrinogen, protein C, protein S, antithrombin III, activated protein C resistance (APCR), and D-dimer) and their clinical significance in 83 CCHF-infected patients. SUBJECTS AND METHODS: We studied 83 CCHF patients who were admitted to Ankara Numune Education and Research Hospital during the spring and summer of2007. We compared the coagulopathy markers of fatal CCHF patients (n=9) with nonfatal cases (n=74). RESULTS: Platelet count, PT, aPTT, INR, and fibrinogen were prognostic factors associated with mortality for CCHF. Especially, platelet count<20 x 10(9) cells/l and aPTT>60 sec were important. Protein C, protein S, APCR, and antithrombin III levels were not associated with mortality. CONCLUSION: Laboratory tests including classical parameters (platelet count, PT, aPTT, INR, and fibrinogen) of coagulopathy seem to be enough for the followup of CCHF. Protein S, protein C, APCR, and D-dimer levels were not associated with mortality.

Community-acquired acute bacterial meningitis in the elderly in Turkey.

This investigation aimed both to delineate the current status of community-acquired acute bacterial meningitis and to produce data on the interrelationships between clinical, laboratory and therapeutic parameters in the elderly. This retrospective cohort study was conducted in 28 Turkish institutions in 159 culture-positive patients over the age of 50 years. Streptococcus pneumoniae was the most common pathogen (69.2%), followed by Listeria monocytogenes (8.8%). For this reason, antilisterial antibiotics such as ampicillin or benzylpenicillin should be added to the therapeutic regimen. Pathogen-specific mortality did not vary between S. pneumoniae and L. monocytogenes. The overall mortality was 2.5% at the third day, 12.6% at the seventh day, 20.1% at the 14th day and 21.4% at the 21st day. The risk factors for fatality were increasing age, the presence of stupor, sepsis and inappropriate antibiotic administration. Cerebrospinal fluid (CSF) leukocyte counts and CSF/blood glucose ratios were lower in patients who died. Fever did not differ between survivors and fatal cases. The mean duration of antibiotic therapy in survivors was 16.3 +/- 6.4 days. One-fifth of the patients had complications, and in 5.7% of the patients sequelae persisted at follow-up.

Glomerulonephritis associating parvovirus B19 infection.

We report a previously healthy, immunocompetent 17-year-old male patient, who developed acute glomerulonephritis during the course of Parvovirus B19 infection and this acute glomerulonephritis did not resolve spontaneously. His renal biopsy showed mild mesangial proliferation and focal segmental sclerosis. Parvovirus B19 DNA was detected in renal tissue by polymerase chain reaction.
