Instructions: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: To investigate changes in autoreactive T-cell responses against PMP-22 and P2 antigen as well as a T-cell memory repertoire in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) induced by repeated intravenous immunoglobulin (IVIg) treatment.', 'In an observational trial, we prepared cryopreserved human peripheral blood monocytes from blood from 34 patients with CIDP (18 treatment naive and 16 maintenance IVIg treatment) and from 14 healthy controls (non-immune neuropathy and healthy control). Treatment response was defined by clinical evaluation. The autoantigen-specific T-cell response was analysed by enzyme linked immunosorbent spot (ELISPOT) assay before IVIg start (baseline) and at follow-up. The T-cell memory subsets were analysed by using flow cytometric analysis.', 'Myelin-derived P2-specific and PMP-22-specific IFN- producers were increased in IVIg responders compared with non-responders before treatment, which decreased by repeated IVIg infusion cycles. Treatment responders but not non-responders showed higher frequencies of CD4 T effector memory (TEM) and T central memory frequencies at baseline compared with maintenance IVIg treatment patients and controls. In addition, IVIg treatment was associated with a significant reduction in CD8 TEM at follow-up.
Output:
Does effective treatment with intravenous immunoglobulins reduce autoreactive T-cell response in patients with CIDP?
