Abstract

The loss-of-function mechanism in progranulin (PGRN) mutation carriers makes PGRN an interesting target for upregulation as a therapeutic approach in neurodegenerative diseases like frontotemporal lobar degeneration. This gives rise to several questions: (1) how stable are PGRN levels in blood and cerebrospinal fluid (CSF) in follow-up? (2) Is it necessary to measure PGRN levels in CSF to monitor a therapeutic effect? Therefore, concentrations of PGRN were measured in paired CSF and serum samples of 22 patients with behavioural variant frontotemporal dementia, including one GRN mutation carrier (c.349+1G>C), 16 patients with amyotrophic lateral sclerosis and 17 non-neurodegenerative patients, which included 22 follow-up levels. PGRN levels of 14 patients with isolated dysfunction of the blood-CSF barrier were measured and PGRN was correlated with albumin quotients as a marker for blood-CSF barrier function. The intrathecal fraction of PGRN was calculated on the basis of CSF-to-serum ratios and hydrodynamic properties. Follow-up measurements of CSF and serum PGRN levels did not show any significant change in diagnostic groups. Mean PGRN levels are 35 times higher in blood than in CSF. However, the CSF-to-serum PGRN ratio does not correlate with the albumin quotient even in patients with severe impairment of the blood-CSF barrier. The calculated intrathecal fraction of CSF PGRN levels ranged between 80 and 90 %. Assuming that CSF PGRN is either brain-derived or transported from…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
