GP88 (Progranulin; PGRN) is a secreted glycosylated protein with important functions in several processes, including immune response and cancer growth. Recent reports have shown that PGRN is a therapeutic target for rheumatoid arthritis (RA) because of its capability to bind with tumor necrosis factor receptor (TNFR). However, the serum PGRN level in RA patients has not been investigated. We used enzyme-linked immunosorbent assay (ELISA) to quantify the serum levels of PGRN in 417 healthy subjects, 56 patients with RA and 31 patients with osteoarthritis (OA). In RA patients, we also measured the serum TNF-α and sTNFR concentration. Immunohistochemical staining of PGRN was performed using synovectomy tissue of RA patients. The serum PGRN normal range was established as 40.1 ± 8.7 ng/ml. PGRN levels were not influenced by sex or age. A significant increase in serum PGRN levels was observed in RA (50.2 ± 11.1 ng/ml) and OA (45.4 ± 6.6 ng/ml) groups compared to those in age-matched healthy controls (40.4 ± 9.9 ng/ml) (p<0.05, Tukey). Further, PGRN levels in the synovial fluid of RA patients (68.4 ± 3.4 ng/ml) were found to be significantly higher than those in OA patients (35.9 ± 16.8 ng/ml). Immunohistochemical staining of PGRN revealed that the highest positive signal was detected in macrophages. Circulating PGRN in RA patients was weakly associated with TNF-α and sTNFR 2 concentration. Furthermore, PGRN/TNF-α ratio was correlated the stage of the disease in RA patients. The concentrations of serum PGRN in RA were found to be significantly higher than those in age-matched healthy controls, although it remains to be clarified how blood PGRN is related to the pathogenesis of RA. Our results showed that the serum PGRN may be a useful approach to monitor the disease activity in RA patients.

A 58-year-old female presented with a unique case of multifocal primary intracerebral malignant fibrous histiocytoma (MFH) manifesting as partial seizure. Neuroimaging showed a mass lesion in the right frontal lobe, which was totally removed. The histological diagnosis was MFH. Follow-up neuroimaging one month after surgery showed another lesion rapidly growing in the left frontal lobe. This lesion was totally removed, and identified as MFH. Her condition gradually worsened. Neuroimaging performed 3 months after first operation revealed bilateral recurrence. She died of respiratory failure 7 months after the initial diagnosis of MFH. Primary intracranial MFH is an extremely rare entity with only 31 cases of solitary tumor previously reported.

Background and purposeWe report the results of endosaccular coil embolization of asymptomatic unruptured intracranial aneurysms (UIAs) in elderly patients (≥65 years).MaterialsThere were 375 elderly patients with 400 asymptomatic UIAs. Patients were divided into two groups: group A included patients aged 65–74 years and group B patients aged ≥75 years.ResultsEndovascular procedures were completed in 97.8% of patients. Immediate anatomical outcomes showed complete occlusion in 53.7%, residual neck in 18.9%, and residual aneurysm in 27.4%. Anatomical follow-ups (mean 36.3±28.1 months) were unchanged in 55.7%, improved in 22.6%, minor recurrence in 11.5%, and major recurrence in 10.2%. Procedure related complications occurred in 31 patients (8.3%). 15 patients had ischemic and 10 hemorrhagic complications. Retreatments were performed in 16 patients (4.3%). Among 366 patients technically completed, 363 (99.2%) showed a favorable clinical outcome (modified Rankin Scale (mRS) score <1) at 30 days. The remaining three patients showed a worsening of mRS >0 at 30 days. The latest clinical follow-up outcomes showed: mRS score 0 in 362 patients; mRS score 1 in one; mRS score 3 in one; mRS score 4 in one; and mRS score 5 in one patient. Permanent morbidity and mortality rates were 1.1% and 0%, respectively. There were no statistically significant differences in gender, comorbidities, aneurysm size, neck width, dome-to-neck ratio, immediate anatomical outcomes, anatomical follow-up outcomes, or procedure related complications between the groups.ConclusionsEndosaccular coil embolization is safe and feasible for elderly patients with asymptomatic UIAs. Old age itself should not be a contraindication.
