RESULTS: The rare C allele frequency of TBXA2R+795T>C was significantly higher in AIA than in ATA (P=0.03) and the TBXA2R+795T>C polymorphism was also associated with extent of percent fall in forced expiratory volume in 1 s (FEV1) after the inhalation of lysine-acetyl salicylic acid in AIA patients (P=0.009); AIA patients homozygous for the +795 C allele had a greater percent fall of FEV1 compared with individuals with TBXA2R+795 CT or TT genotypes. The frequency of patients carrying both the TBXA2R+795T>C rare allele and HLA DPB1(*)0301 was significantly higher in AIA patients (29.4%) than in ATA patients (7.3%) (P=0.008, odds ratio=5.3). CONCLUSION: These results suggest that the polymorphism of TBXA2R+795T>C may increase bronchoconstrictive response to ASA, which could contribute to the development of the AIA phenotype.

Guest guest Posted June 15, 2008 Report Share Posted June 15, 2008 So, an update on my angina... I decreased my aspirin to 325 mg/day on June 4th. Prior to that date, I was experiencing chest pain almost everyday, if not multiple times a day. Since the decrease in aspirin, I have only had pain twice. Whether or not my doctors believe it, this seems like a pretty straight forward conclusion to me. Nothing else has changed... not medication, not lifestyle, not food, nothing. Aspirin is the only variable. Between the abstracts that you've found, the research that I have done, and my own experience, I think this is enough information to hopefully convince my ENT that some further studies need to be done. We'll see. Kate P.S. Luckily I've found another support group for variant angina. I also asked them if anyone there suffered from " allergies " and whether they thought it was related. I didn't want to bring up Samter's since there are probably a lot of undiagnosed people out there that just think they have allergies/asthma. Anyway, no one there seemed to think there was any relationship either. For everyone's sake, I hope there isn't. But maybe I'm living proof that there is. > > I found by chance this abstract, which says that some people have > genetic thromboxane receptor defects, and that they are more likely to > have aspirin-intolerant asthma.

Guest guest Posted June 15, 2008 Report Share Posted June 15, 2008 No one in my family has polyps, aspirin sensitivity, ear problems, or asthma but me. My father is 87 - my mother died at 72 following a heart valve replacement surgery but her death was due to human error in the hospital.

Guest guest Posted June 16, 2008 Report Share Posted June 16, 2008 I developed my asthma when I was 27 after a bout of very bad bronchitis and the rest as they say is history. I have a daughter just turned 23 and she doesn’t have any allergies, asthma or anything and I’m praying that she’s going to stay that way. I’m not sure if I have IBS or not but I certainly have some of the symptoms. As to stress, yes that does play a huge part, I went through a very upsetting divorce five years ago and had shocking asthma at that stage and about six months later had to undergo polyp surgery. Maybe we could get a poll going with some of the symptoms we have?

Guest guest Posted June 16, 2008 Report Share Posted June 16, 2008 I too think that stress is a factor in triggering Samters. I come from an asthmatic family - my father and two sisters and a brother all had it. My sibblings had it in childhood and have largely grown out of it. I escaped for most of my life and had only hayfever to contend with. For me Samters symptons all came along soon after a very messy divorce. It took me over 2 years to get my ex to agree to a settlement - she engaged a solicitor who was intent upon draining our resources rather than reaching a deal, but unfortunately my ex believed everything he said. She had to eventually settle on less than I had offered 18 months earlier as he had messed up big time. However there are no victors in such things and perhaps I escaped financially better than might have been the case without the fight but health wise I now pay a very high price. There is always a silver lining and I developed a much closer bond with my three children during that stressful time and the words in the three fathers day cards I had hand delivered yesterday lifted my spirits after a rotten Samters week. Two of my children had chronic childhood asthma but one, like me, escaped. They are all fine young adults now, making their way in the world. Suffice to say I'm a proud dad!

From: Mike Hammond [mailto:rovenmike@...] Sent: Monday, 16 June 2008 10:52 PM samters Subject: RE: Variant angina and Samter's I too think that stress is a factor in triggering Samters. I come from an asthmatic family - my father and two sisters and a brother all had it. My sibblings had it in childhood and have largely grown out of it. I escaped for most of my life and had only hayfever to contend with. For me Samters symptons all came along soon after a very messy divorce. It took me over 2 years to get my ex to agree to a settlement - she engaged a solicitor who was intent upon draining our resources rather than reaching a deal, but unfortunately my ex believed everything he said. She had to eventually settle on less than I had offered 18 months earlier as he had messed up big time. However there are no victors in such things and perhaps I escaped financially better than might have been the case without the fight but health wise I now pay a very high price. There is always a silver lining and I developed a much closer bond with my three children during that stressful time and the words in the three fathers day cards I had hand delivered yesterday lifted my spirits after a rotten Samters week. Two of my children had chronic childhood asthma but one, like me, escaped. They are all fine young adults now, making their way in the world. Suffice to say I'm a proud dad!

I have a daughter just turned 23 and she doesn’t have any allergies, asthma or anything and I’m praying that she’s going to stay that way. I’m not sure if I have IBS or not but I certainly have some of the symptoms. As to stress, yes that does play a huge part, I went through a very upsetting divorce five years ago and had shocking asthma at that stage and about six months later had to undergo polyp surgery. Maybe we could get a poll going with some of the symptoms we have?

I varied my diet and found that wheat caused my IBS so now I avoid wheat. Before Samters I was fine eating wheat. I have had tests and am not a Coeliac. Just a thought.

Department of Allergy and Rheumatology, Ajou University School of Medicine, Suwon, Korea. BACKGROUND AND OBJECTIVE: The thromboxane A2 receptor (TBXA2R) is a receptor for a potent bronchoconstrictor, TBXA2 which is known to be related to bronchial asthma and myocardial infarction. TBXA2R antagonist and TBX synthase inhibitors have been found to be effective in the management of asthmatic patients. This study was aimed to evaluate whether genetic variants of TBXA2R may be related with development of acetyl salicylic acid (ASA)-intolerant asthma (AIA). METHODS: TBXA2R gene polymorphisms (TBXA2R+795T>C, TBXA2R+924T>C) were determined using a single-base extension method in 93 AIA patients compared with 172 patients with ASA-tolerant asthma (ATA) and 118 normal controls (NCs) recruited from the Korean population. HLA DPB1*0301 genotype was performed using a direct sequencing method. RESULTS: The rare C allele frequency of TBXA2R+795T>C was significantly higher in AIA than in ATA (P=0.03) and the TBXA2R+795T>C polymorphism was also associated with extent of percent fall in forced expiratory volume in 1 s (FEV1) after the inhalation of lysine-acetyl salicylic acid in AIA patients (P=0.009); AIA patients homozygous for the +795 C allele had a greater percent fall of FEV1 compared with individuals with TBXA2R+795 CT or TT genotypes. The frequency of patients carrying both the TBXA2R+795T>C rare allele and HLA DPB1(*)0301 was significantly higher in AIA patients (29.4%) than in ATA patients (7.3%) (P=0.008, odds ratio=5.3). CONCLUSION: These results suggest that the polymorphism of TBXA2R+795T>C may increase bronchoconstrictive response to ASA, which could contribute to the development of the AIA phenotype. Sent from .

Guest guest Posted June 16, 2008 Report Share Posted June 16, 2008 Mine came after a very stressful period too - we were redecorating our bedroom and had time-limit of a weekend to complete painting before a new carpet was to be fitted. Also, our toddler and baby came down with chicken pox and both were covered and our baby boy hasd such a high temp he went into hospital for a while. I was so stressed with it all and didn't sleep for 3 days, then started what I thought was a cold, but it didn't stop, it just carried on for weeks and weeks getting worse - it was the samters developing, first the polyps and sinusitis then the asthma. But that difficult weekend was the start of it all.I know it's not as stressful as divorce, but I still remember how very stressed I felt - it was an acute stress on top of longer-term stress. Also, my symptoms are always worse now when I'm stressed...that makes sense really! BeckyBob <rthomp0215@...> wrote: It could. Mine came after a very stressful period.

Guest guest Posted June 16, 2008 Report Share Posted June 16, 2008 I suffered with IBS for most of my young life through about my early 30s. I found, and research supports, that if you take at least, 250mg of magnesium a day, the symptoms go away. Many believe that IBS is directly related to a magnesium deficiency. I find that when I start skipping it, I run into trouble again. I take 500 mg. daily at bedtime.

The frequency of patients carrying both the TBXA2R+795T>C rare allele and HLA DPB1(*)0301 was significantly higher in AIA patients (29.4%) than in ATA patients (7.3%) (P=0.008, odds ratio=5.3). CONCLUSION: These results suggest that the polymorphism of TBXA2R+795T>C may increase bronchoconstrictive response to ASA, which could contribute to the development of the AIA phenotype. ------------------------------------ Quote Link to comment Share on other sites More sharing options...
Guest guest Posted June 16, 2008 Report Share Posted June 16, 2008 I have been diagnosed with Samters almost as long as I have been married! That's 28 years! I often tell my hubby that he is the number one Polyp in my life. Actually, our life has been anything but stress-free and I can most definitely note times in my life when flare ups occurred at very stressful times. In fact, most of my 13 polyp surgeries seemed to always happen at the worst times, when we had no money or some other significant issue was happening at the same time. I definitely feel there is a relationship between stress and flare-ups.

Guest guest Posted June 18, 2008 Report Share Posted June 18, 2008 Samter's is indeed genetic in origin, ie patients have what is called a gene polymorphism (or maybe several, this is not really that well established), meaning a genetic variation, that affects what is known as the arachidonic acid metabolism, a chemical cascade of reactions, and this pathway does not function exactly the way it ought to. But empirical observations show that this does not mean at all that all descendants of a patient will develop the disease, and even if it develops in some children, the form it takes may vary from one generation to the other as well as from one sibling to another. Like all genes, there is no certainty that the gene will be inherited in the same form, and even then, there is no certainty that the gene will express itself. Many genes stay quiet for the better ! To express itself, it has been hypothesized that this gene (like others, this is not really specific behaviour) needs triggers that can be internal or environmental. Some articles speak of viruses, smoke, diesel particles or similar things as potential triggers. Maybe taking aspirin or NSAIDS can be counted as triggers, meaning that they may " wake up " the gene, but I don't remember if it has been demonstrated or not. So, whatever, the sensible attitude should be that, since we do not know whether or not our children have inherited any gene, they should be as reasonably as possible spared excessive exposure to potential triggers. For instance, smoking would be a risk ; working in a heavily polluted environment might be another ; same thing for taking aspirin or NSAIDS. > > Afyso, > > If aspirin sensitivity is genetic then I will shoot myself (joke).

Guest guest Posted July 18, 2008 Report Share Posted July 18, 2008 Excellent, I think taking all the med’s affect our nervous systems as I am jumpy and have palpatations for no reason, I have cut back to 2 coffee’s max a day and sometimes none and taking some supplements make me feel a little more relaxed. I aim to cut my coffee/caffeine intake further and I never ever drink soft drinks like , fanta, sprite, coke etc these are a definite no no for samters sufferers. It took me years to completely stop as I loved coke, Irn Bru, lemonade but it’s makes a huge difference. Also without getting any deeper into this subject I love my wine and have now found some great Organic brands which I stock up on, cheap wine generally means more acid and more problems with sneezing etc with sulphites but this is an area most samters suffers should look at sorting out, and also I do not drink beer/lager it gives me an instant sore head and the hangover is terrible.

Guest guest Posted July 18, 2008 Report Share Posted July 18, 2008 Actually, I think it more boils down to what affects different people and how. I live on caffeine. I drink a 16 oz travel mug of coffee in the morning and at least 3 12 oz diet coke's every day during the week. There was a period a couple years ago I had to go completely off caffeine for several months due to unexplained tachycardia. I did not notice any improvement in my sinus health during that time. And the tachycardia was never explained but ultimately blamed on stress and less-than-fully-controlled asthma (and it did go away and I am back to drinking my normal amount of caffeine!). I drink beer and wine. Yes, they stuff me up and usually after 1 beer or 1-2 glasses of wine I am stuffy and can't smell anything but by morning I am fine, so I refuse to give them up. Sometimes I drink these things and don't have problems, sometimes the problems are worse. No idea what it is, but I suspect alcohol in general as mixed drinks will also make me stuffy. Go figure. But I think it boils down to no, I can't explain what it is in beer that affects you. For me I suspect it is my strong grass allergies affecting me. But who knows? K.

Guest guest Posted July 22, 2008 Report Share Posted July 22, 2008 I’m sure the medications have to affect the nervous system. I was put on anti depressants because of anxiety attacks and still get jumpy or agitated, more so if I have too much coffee or fizzy drinks. In Australia there’s organic wines and I’ve found them to be excellent as I love the odd glass. I would have around two beers a year if that and only if it’s very hot and I’m extremely thirsty, but they’re ‘lite’ so no problems. I’m going to try the magnesium supplements though after reading your comment Beverley From: Steve [mailto:skunkburner@...] Sent: Saturday, 19 July 2008 2:24 AM samters Subject: RE: Re: Variant angina and Samter's Importance: High Excellent, I think taking all the med’s affect our nervous systems as I am jumpy and have palpatations for no reason, I have cut back to 2 coffee’s max a day and sometimes none and taking some supplements make me feel a little more relaxed. I aim to cut my coffee/caffeine intake further and I never ever drink soft drinks like , fanta, sprite, coke etc these are a definite no no for samters sufferers. It took me years to completely stop as I loved coke, Irn Bru, lemonade but it’s makes a huge difference. Also without getting any deeper into this subject I love my wine and have now found some great Organic brands which I stock up on, cheap wine generally means more acid and more problems with sneezing etc with sulphites but this is an area most samters suffers should look at sorting out, and also I do not drink beer/lager it gives me an instant sore head and the hangover is terrible. Any beer/lager drinkers out there to comment on this, I just can’t handle beers/lagers not sure if it’s the chemicals , wheat whatever, yeast…… Cheers Steve From: samters [mailto:samters ] On Behalf Of Beverley Paine Sent: 16 July, 2008 20:06 samters Subject: Re: Variant angina and Samter's Steve, you described me to a 'T': a real stress bunny, always looking for something to do, happiest when I'm busy or around others who are busy (although I do love sitting and talking for hours on end!), and yes, since I started taking magnesium supplements my life is a lot more balanced and my symptoms lessened.

Guest guest Posted July 22, 2008 Report Share Posted July 22, 2008 I cannot drink any alcohol, especially wine. My understanding is that it is the yeast used in the fermenting process that is left over especially in wine and beers that is the culprit.
