    Carbamazepine, Sodium Valproate and Levetiracetam Modulate Wnt Inhibitors in Indian Women with Epilepsy
    (National Academy of Medical Sciences (India), 2018-07) Bushra, Parveen; Tripathi, Manjari; Vohora, Divya
    Background:Antiepileptic drug (AED) therapy has been claimed to deteriorate bone health. Majority of the research was inclined towards vitamin-D deficiency as the patho-mechanism. However, after the role of Wnt in bone metabolism was discovered, it has paved way for investigating the role of Wnt inhibitors in mediating effects on bone accrual. Recently, we have reported the modulation of two Wnt inhibitors, sclerostin and dickkopf-1 (DKK-1), following AED therapy in Indian women with epilepsy, however, the subgroup analysis for individual drug is elucidated in this report. Methods: Individual analysis for our earlier cross-sectional study on three AEDs, carbamazepine (CBZ), sodium valproate (SVP) and levetiracetam (LTM), on sclerostin and dickkopf-1, and their correlation with receptor activator of nuclear factor kappaB ligand (RANKL) and serum 25-hydroxy vitamin D (25OHD) was assessed in Indian women with epilepsy. Results: We observed enhanced sclerostin and 25OHD levels with all three AEDs while serum RANKL was higher with SVP and LTM only. Further, serum DKK-1 levels were lowered with CBZ and LTM. Sclerostin showed a positive correlation with RANKL in CBZ group, while DKK-1 presented no such relationship

    Effect of combined treatment of thioperamide with some antiepileptic drugs on methionine-sulfoximine induced convulsions in mice.
    (2010-08) Vohora, Divya; Khanam, Razia; Pal, Shanthi N; Pillai, K K
    Methionine-sulfoximine (MSO), a convulsant is known to increase the activity of histamine N-methyl transferase. The effect of a selective H3 receptor agonist R- ( ) methylhistamine (RAMH) and antagonist (thioperamide, THP) and some antiepileptic drugs (gabapentin and sodium valproate) have been evaluated on MSO-induced convulsions in mice. The effect of THP was also evaluated in combination with these antiepileptic drugs. Sodium valproate (300 mg/kg, po) and gabapentin (400 mg/kg, po) offered protection against MSO-induced convulsions as evidenced by a significant prolongation of latency to abnormal dorsoflexion and complete protection against mortality within 6 h of administration. THP (15 mg/kg, ip) alone and in combination with sub-effective doses of gabapentin (75 mg/kg, po) and sodium valproate (75 mg/kg, po) revealed no significant differences from the control group or either drug alone. Hence, the convulsant action of MSO does not appear to be mediated via histaminergic mechanisms.
