Study Links Autism and Mother's Illnesses
http://www.healthsentinel.com/news.p...st_item&id=596
"Study Links Autism and Mother's Illnesses", Reuters, February 7, 2005, Link: http://www.reuters.com/newsArticle.j...toryID=7560399 Expectant mothers suffering from asthma, allergies or a type of skin disease have a higher risk of giving birth to an autistic child, a study said on Monday. Asthma, allergies and psoriasis symptoms during pregnancy -- especially if diagnosed in the second trimester -- doubled the risk of autism in children compared to children who were not afflicted, researchers from Kaiser Permanente in Oakland, California, said. Autism is a mysterious condition that strikes roughly six in 1,000 children, mostly boys, and is associated with diminished social skills and an adherence to routines. The study looked at 88,000 children belonging to the Kaiser Permanente health plan born in Northern California between 1995 and mid-1999, 420 of whom were diagnosed with autism. The researchers said there was no statistical link between autism in children and 44 autoimmune diseases in mothers, including rheumatoid arthritis, lupus and multiple sclerosis. The exception was psoriasis, which doubled the risk of autism. Previous research has suggested there may be a link between autoimmune disease during pregnancy and autism, because autistic children often have high levels of autoimmune response chemicals in their bloodstreams. Women make up 78 percent of patients with autoimmune diseases, where the body's immune system attacks its own tissues. The report, which was published in The Archives of Pediatrics and Adolescent Medicine, speculated that there may be a common underlying genetic cause to such ailments as asthma and autism. Or, because the mother's condition was frequently diagnosed in the second trimester, the flare-up may have caused her immune system to produce more cytokines, which are associated with inflammation and could have damaged fetal brain development. |

Ah, something new to stress over!! I developed sneezy, itchy hayfever-like allergies around the beginning of my 2nd trimester. I use Nasonex to keep it under control (strangely, my neck and the skin under my chin get itchy with the allergy too, and nothing seems to help that). Well, nothing to be done but wait and see.

Asthma, allergies and psoriasis symptoms during pregnancy -- especially if diagnosed in the second trimester -- Does that mean diagnosed for the first time in the second trimester? Or existing chronically, continuing into the second trimester? Hope -- Riley 1993 c/s Tara 2002 HBAC #3 Sept 2005! http://groups.yahoo.com/group/crunchy_september_mamas/ |

@c13g2000cwb.googlegroups.com: Ah, something new to stress over!! I developed sneezy, itchy Not yet. Studies like the one described very often come up with false leads. The problem is that if you look for statistical associations between some outcome (say autism) and a large number of different potential causes (at least 47 different maternal conditions) in a single study, it's *very* likely that you'll see at least one association that meets the test of statistical significance but is merely due to chance. If, say, you find an association between autism and maternal asthma in such a study, all you've learned is that you need to do another study, with a different sample, looking *only* at that possible association. If one doesn't show up, it means that the original association in the multifactorial study was just due to the random characteristics of the sample involved. A study that looks at only one factor will be much less likely to come up with a false association than one that looks at many. |
