Abstract Background In 2002, CDC initiated the Anthrax Vaccination Program (AVP) to provide voluntary pre-exposure anthrax vaccination for individuals at high risk for exposure to Bacillus anthracis spores. The AVP offered an opportunity to investigate hypothesized reasons for a reported gender difference in injection site adverse events (AEs) following anthrax vaccine adsorbed (AVA). Objectives To evaluate in women the impact of body mass index (BMI), pre-vaccination serum progesterone levels, and pre-vaccination anti-anthrax protective antigen immunoglobulin G concentrations (anti-PA IgG) on the occurrence of AEs following subcutaneous AVA vaccination. Methods Participants' BMI was determined at enrollment. Also, pre-vaccination blood samples were assayed for serum progesterone and anti-PA IgG. Post-vaccination solicited AEs were recorded by participants using a 4-day diary card. Results Obese group had an elevated risk for arm soreness. Decreased pre-vaccination serum progesterone level was associated with arm swelling. Increased pre-vaccination anti-PA IgG was associated with itching on the arm; and within the obese group, was associated with arm swelling, lump or knot, redness, soreness, and warmth. Conclusions In AVA vaccinated women, obesity was associated with arm soreness and decreased pre-vaccination serum progesterone levels were associated with increased rate of arm swelling. Increased pre-vaccination anti-PA IgG may be associated with an increased frequency of itching on the arm, and in obese women, may increase the occurrence of arm swelling, lump or knot, redness, and warmth. Administering AVA according to a woman's menstrual phase may reduce the occurrence of certain injection site reactions. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Forearm blood flow in pre-eclampsia

Objective 1. To characterise the forearm vascular reactivity of women with pre-eclampsia in the third trimester of pregnancy and compare it with that in normal or gestational hypertensive pregnancies. 2. To document female sex steroid (oestradiol, progesterone, oestriol and ,hCG) levels in the three groups of women. Design Forearm blood flow was measured by venous occlusion plethysmography during intra-arterial infusion of saline and vasoactive substances: angiotensin II, sodium nitroprusside, acetylcholine and NG -monomethyl- l -arginine (l -NMMA). Setting Research laboratory at St George Hospital, Kogarah, Sydney, Australia. Sample Fifteen non-pregnant women in the follicular phase of the menstrual cycle, 15 third trimester normal pregnant women, 13 women in the third trimester with gestational hypertension and 15 women with pre-eclampsia. Main outcome measures Changes in forearm blood flow in response to vasoactive substances. Results Normal pregnant women had higher baseline forearm blood flow than non-pregnant women, decreased vasodilator responses to sodium nitroprusside and reduced vasoconstrictor responses to angiotensin II. No difference in response to angiotensin II, sodium nitroprusside or l -NMMA was found among normal pregnant, pre-eclampsia or gestational hypertension women, but vasodilatory responses of pre-eclamptic women to acetylcholine were reduced compared with normal pregnant women. Higher serum progesterone levels were found in women with pre-eclampsia and gestational hypertension than in normal pregnancy. Conclusion The hyperdynamic circulation of normal pregnancy is characterised by refractoriness to angiotensin II but this is not altered in pre-eclampsia. Pre-eclamptic women demonstrate a reduced vasodilator response to acetylcholine which, in the absence of any alteration in response to l -NMMA, implies that factors other than nitric oxide deficiency mediate the vasoconstriction of pre-eclampsia.
