The local peripheral antihyperalgesic effect of levetiracetam and its mechanism of action in an inflammatory pain model.
    Anesthesia and analgesia, 2012, Volume: 115, Issue:6

    We have recently shown that levetiracetam, administered systemically, exerts an antihyperalgesic effect in a rat inflammatory pain model. In this study, we examined whether levetiracetam has local peripheral antihyperalgesic/anti-edematous effects in the same model of localized inflammation and whether opioidergic, adrenergic, purinergic, 5-HTergic, and GABAergic receptors are involved in its antihyperalgesic action.. Rats were intraplantarly (IPL) injected with carrageenan. A paw pressure test was used to determine the effect/s of (a) levetiracetam when applied IPL, on carrageenan-induced hyperalgesia, and (b) naloxone (a nonselective opioid receptor antagonist), CTAP (a selective μ-opioid receptor antagonist); yohimbine (a selective α(2)-adrenoceptor antagonist), BRL 44408 (a selective α(2A)-adrenoceptor antagonist), MK-912 (a selective α(2C)-adrenoceptor antagonist); caffeine (a nonselective adenosine receptor antagonist), DPCPX (a selective adenosine A(1) receptor antagonist); methysergide (a nonselective 5-HT receptor antagonist), GR 127935 (a selective 5-HT(1B/1D) receptor antagonist); and bicuculline (a selective GABA(A) receptor antagonist), all applied IPL, on the levetiracetam-induced antihyperalgesia. Moreover, levetiracetam's influence on paw inflammatory edema was measured by plethysmometry.. Levetiracetam (200-1000 nmol/paw) produced a significant dose-dependent reduction of the paw inflammatory hyperalgesia and edema induced by carrageenan. Naloxone (75-300 nmol/paw), CTAP (1-5 nmol/paw); yohimbine (130-520 nmol/paw), BRL 44408 (50-200 nmol/paw), MK-912 (5-20 nmol/paw); caffeine (500-1500 nmol/paw), DPCPX (3-30 nmol/paw); methysergide (10-100 nmol/paw) and GR 127935 (50-200 nmol/paw); but not bicuculline (400 nmol/paw), significantly depressed the antihyperalgesic effects of levetiracetam (1000 nmol/paw). The effects of levetiracetam and antagonists were attributed to local peripheral effects because they were not observed after administration into the contralateral hind-paw.. Our results show that levetiracetam produces local peripheral antihyperalgesic and anti-edematous effects in a rat model of localized inflammation. Antihyperalgesia is at least in part mediated by peripheral μ-opioid, α2A,C-adrenergic, A1 adenosine, and 5-HT1B/1D receptors, but not by GABAA receptors. These findings could contribute toward a better understanding of the analgesic effects of levetiracetam, and improved treatments of inflammatory pain with a lower incidence of systemic side effects and drug interactions of levetiracetam.

Short report: A calcified Taenia solium granuloma associated with recurrent perilesional edema causing refractory seizures: histopathological features.
    The American journal of tropical medicine and hygiene, 2011, Volume: 85, Issue:3

    We describe the first detailed histological description of an excised calcified Taenia solium granuloma from a patient who developed recurrent seizures associated with perilesional edema surrounding a calcified cysticercus (PEC). The capsule, around a degenerated cysticercus, contained marked mononuclear infiltrates that extended to adjacent brain, which showed marked astrocytosis, microgliosis, and inflammatory perivascular infiltrates. The presence of large numbers of mononuclear cells supports an inflammatory cause of PEC. Immunosuppression or anti-inflammatory measures may be able to treat and prevent PEC and recurrent seizures.
