The aim of this pilot study was to determine health-related quality of life (HRQoL) in patients with history of medication overuse headache (MOH) after detoxification and a headache-specific inpatient rehabilitation program and to receive necessary information for future prospective studies.HRQoL and headache-related disability were cross-sectionally measured by Short Form 36 (SF-36), Hospital Anxiety and Depression Scale (HADS), Migraine Disability Score (MIDAS), Coping Strategies Questionnaire (CSQ), and Symptom Checklist 90 revised (SCL-90-R).
When genotype distribution for RAMP1rs7590387 was compared between healthy controls (n = 209) and MOH patients, carriers of rs7590387GG were found at lower risk of developing MOH (OR: 0.43, 95%CI: 0.22-0.85, P = 0.011).
In this association study, we sequenced all exons, intron/exon junctions, and 3'-5'UTR regions of HDAC3 in 23 MOH patients to investigate its role in medication overuse.
In the present study, we aimed to evaluate the role of 14 polymorphisms in 8 candidate genes potentially relevant for drug addiction (OPRM1, DRD2, DBH, COMT, BDNF, SLC6A4, 5HT2A, and SLC1A2) as predictors for detoxification outcome of MOH patients at 2 months of follow-up.
By multivariate logistic stepwise regression analysis, type of migraine, regular and sufficient dietary intake, and methylenetetrahydrofolate reductase (MTHFR) C677T (rs1801133) and dopamine D2 receptor (DRD2) rs6275" genes_norm="1813">C939T (rs6275) polymorphisms were selected as significant factors that contribute independently to the development from migraine to MOH (P < 0.05).
We therefore sought differences in SSEP sensitization and habituation in patients with MOH who underwent angiotensin converting enzyme (ACE) I/D polymorphism analysis.
In conclusion, our studydoes not provide evidence that the 5HTT, 5-HT1A, 5HT1B,5HT2A and 5HT6 gene polymorphisms play a role in the genetic predisposition to MOH.
In conclusion, our studydoes not provide evidence that the 5HTT, 5-HT1A, 5HT1B,5HT2A and 5HT6 gene polymorphisms play a role in the genetic predisposition to MOH.
These findings showed an influence of examined BDNF polymorphism in the MOH clinical features, supporting the idea that MOH is a substance abuse disorder.
