    It is well known that there might be an epidemiological association between Helicobacter pylori infection and extraintestinal diseases. This study aimed at determining H. pylori infection in epileptic patients. Forty-seven cryptogenic epileptic patients (Group 1) and 35 healthy people (Group 2) participated in this study. Presence of H. pylori infection was examined by H. pylori stool antigen (HpSA), H. pylori IgG, and IgM. HpSA was detected in 21 participants (44.6%) in Group 1 and in 3 participants (8.5%) in Group 2. H. pylori IgM was positive in 27 participants (57.4%) in Group 1 and in 8 participants (22.8%) in Group 2. H. pylori IgG was positive in 37 participants (78.7%) in Group 1 and in 13 participants (38%) in Group 2. The difference of rates of HpSA, H. pylori IgM and IgG in Groups 1 and 2 were found statistically significant (chi(2) = 4.18, p = 0.04; chi(2) = 9.18, p = 0.0017; chi(2) = 14.58, p < 0.001, respectively). We also compared presence of H. pylori infection between the epileptic patients with poor and good prognosis; HpSA positivity was detected in 15 (62.5%) of 24 and 6 (26%) of 23, respectively, and the differences were statistically significant (chi(2) = 6.30, p = 0.012). H. pylori IgM positivity was detected in 16 (66%) of 24 patients with poor prognosis and 11 (47.8%) of 23 patients with good prognosis (p > 0.05). H. pylori IgG positivity was detected in 18 (75%) of 24 patients with poor prognosis and 19 (82.6%) of 23 patients with good prognosis. The differences of H. pylori IgM and IgG positivity rates in epileptic patients with poor and good prognosis were not found statistically significant (p > 0.05). These results suggest a probable association between the acute H. pylori infection and epilepsy, especially with poor prognosis. (C) 2006 British Epilepsy Association. Published by Elsevier Ltd.

    Pregnancy associated plasma protein-A and epilepsy
    (2007) Coşkun, Abdurrahman; Özdemirli, Burcu; Memişoğullari, Ramazan
    Abstract: In this study, we aimed to investigate the role of pregnancy-associated plasma protein-A (PAPP-A) as insulin-like growth factor binding protein-4 (IGFBP-4) protease in epilepsy patients. We studied 16 epilepsy patients and 10 healthy controls. Serum PAPP-A levels of epilepsy patients (6.8 ± 3.2 mU/L) were higher than of the control group (5.1 ± 1.9 mU/L), but the difference was not statistically significant (P > 0.05). We concluded that PAPP-A may increase the bioavailability of insulin-like growth factors (IGFs) due to decreased neurogenesis and synthesis of IGFs in chronically epilepsy patients.
