Metastasis to the skeleton frequently occurs in breast carcinoma patients resulting in different skeletal-related events including pain, hypercalcemia, pathological fracture, and spinal cord or nerve root compression. Bisphosphonates are class of agents most frequently used to reduce skeletal-related events in patients with bone metastases by inhibiting osteoclast activity through inhibition of mevolanate pathway which is also important in cholesterol synthesis. Statins are cholesterol lowering agents and inhibit the same pathway. Therefore statins may also reduce skeletal-related events in breast cancer patients with bone metastases by inhibiting osteoclastic activity.

Job's syndrome or hyper-immunoglobulin E syndrome is a primary immunodeficiency characterized by recurrent staphylococcal abscesses and markedly elevated serum immunoglobulin E concentrations. Here we report a case of a woman with hyper-immunoglobulin E syndrome with a diagnosis of peripheral T-cell lymphoma, and we review the pertinent literature.
BACKGROUND/AIMS: Angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists have beneficial effects on impaired fibrinolytic activity of hypertensive patients. The aim of the study was to evaluate the effect of antialdosterone treatment on impaired fibrinolysis of hypertensive patients. METHODS: Fourteen hypertensive outpatients and 14 normotensive healthy volunteers participated in this study. Blood samples for plasminogen activator inhibitor-1 (PAI-1) antigen and tissue plasminogen activator (t-PA) antigen were obtained at baseline in all patients and control subjects. Then all hypertensive patients used spironolactone 50 mg/day for a week. Blood samples were again obtained after a week of spironolactone treatment. RESULTS: The mean basal plasma level of PAI-1 of hypertensive patients was higher than those of the normotensive control group (60.98 +/- 4.2 vs. 24.09 +/- 1.61 ng/ml, p < 0.01) The mean basal t-PA level was similar in the hypertensive and control subjects (7.49 +/- 0.65 vs. 8.78 +/- 0.92 ng/ml, p > 0.05). The mean PAI-1 level decreased after a week of spironolactone treatment (60.98 +/- 4.2 vs. 42.99 +/- 7.98 ng/ml, p < 0.05). The mean plasma t-PA level of hypertensive patients increased after spironolactone treatment (7.49 +/- 0.65 vs. 11.09 +/- 1.33 ng/ml, p < 0.05). CONCLUSION: This study shows that spironolactone improves impaired fibrinolysis in systemic hypertension. It provides evidence for a direct link between aldosterone and the fibrinolytic system in humans.
