Objectives Cerebral sinus venous thrombosis (CSVT) is a rare stroke subtype that is more common in women, yet data regarding sex-specific characteristics are sparse. We aimed to study male-specific characteristics among patients with CSVT. Materials & methods Data of consecutive patients with CSVT, admitted to a single medical centre between 2005 and 2020, were retrospectively studied. Demographics, clinical presentations, radiological and outcome parameters were compared between male and female patients. Male patients were further divided into older and younger than 35 years old for additional comparisons. Results Out of 15,224 patients diagnosed with stroke, 150 patients (1%) presented with CSVT and 47 (31.3%) of them were males. Males had significantly higher rates of previous thrombotic events (22% vs. 7%, p = .009), malignancies (32% vs. 16%, p = .022) and Behcet's disease (22% vs. 2%, p < .001). Additionally, we found that malignancies were significantly more prevalent in older males (48% vs. 17%, p = .022), while Behcet's disease was more often found in younger patients (35% vs. 9%, p = .032). Additional age-related differences in disease characteristics among male patients included a higher frequencies of papilledema (42% vs. 13%, p = .028), and cortical vein thromboses (21% vs. 0% p = .021) observed in the younger men. Conclusions There are important differences in risk factors for thrombosis between men and women with CSVT. Behcet's disease is common in younger men, while malignancies are major causes of CSVT in older men.
Die Tartrat-resistente saure Phosphatase (TRAP) gilt als Markerenzym der Knochen-resorbierenden Osteoklasten. Die aktive Isoform 5b wurde bei Tumorpatienten als Indikator für einen durch Knochenmetastasen bedingten verstärkten Knochenabbau beschrieben. Bei Bestimmung von TRAP5b im Serum von Mammakarzinom-Patientinnen mit und ohne ossäre Metastasierung im Rahmen einer Studie fanden wir z.T. deutlich erhöhte Werte bei Patientinnen mit ausschließlich viszeraler Filialisierung in Progression.
