High frequency of IgM antiphospholid antibodies in young Iranian patients with stroke

To investigate the presence of IgG and IgM types of anticardiolipin [aCL] and antiphospholipid [aPL] antibodies in younger Iranian patients with ischemic stroke. Both IgG and IgM types of aPL [cardiolipin, anti phosphatidyl inositol, anti phosphatidyl serine, anti phosphatidic acid and beta 2-glycoprotein I [B2-GPI]] and aCL alone [cardiolipin and B2-GPI] were measured in 117 patients with ischemic stroke [aged <45 years] during an 18-month period from September 2002 to March 2004 in Al-Zahra Hospital, Isfahan, Iran. The demographic, clinical, and laboratory characteristics of patients with a positive titer were recorded. Seven men and 16 women [23 patients, 19.6%] had increased IgG types of aPL antibodies. Increased titers of IgM and IgG were found in 19 [82.6%] and 6 [26%] patients for aPL antibodies and in 15 [83.3%] and 8 [44.4%] cases for aCL alone. Despite European studies, high titers of IgM aPL antibodies found in a large number of patients can be caused by the presence of unknown triggering factors [infections or poisons], that are more prevalent in developing countries compared to developed countries. This hypothesis remains to be investigated further

Orthostatic hypotension in Iranian patients with Parkinson's disease

To prospectively investigate the prevalence and clinical relevance of orthostatic hypotension [OH] in Parkinson"s disease [PD] in Isfahan, Iran. We investigated 150 consecutive patients with PD [42 women, 108 men] in Al-Zahra Hospital, Isfahan, Iran from January 2002 to January 2004. Blood pressure was measured first in a supine position following a rest of at least 10 minutes, and then after 3 minutes of active standing. Data concerning the age, gender, duration of disease, and drug consumption were recorded in a questionnaire. Orthostatic hypotension in PD is more frequent in women, patients taking a higher dose of levodopa, in higher age groups, and patients with longer duration of the disease, however, a statistically significant difference was seen in the female group and patients taking a higher dose of levodopa. Orthostatic hypotension is mainly related to PD pathology and the clinical relevance of OH to gender, age, and disease duration may be due to the natural course for progression of human autonomic dysfunction during life. Higher doses of levodopa may increase the risk of OH
