Pre-eclampsia Is Predictable

Pre-eclampsia is a condition, which can threaten a woman’s health and also the unborn baby. It can occur in the second and third trimester. These latter stages of pregnancy (there are 3 stages) are where the doctor should check for early pre-eclampsia signs. In the past this would go unchecked and develop to the full-blown condition of eclampsia and be a significant cause of maternal mortality rate
and fetal mortality rate. With prenatal visits and check-ups the early signs are easily recognized: the pregnant woman would complain that her rings would not fit her any more. Significant weight increase due to fluid retention where her legs and the area of her shinbone would be puffy, is called edema. The dipstick test would tell more: it would indicate the presence of protein in the urine sample. These changes are a cause of high blood pressure, which is another important clinical sign and can be readily checked. For these reasons it is imperative that regular pre-natal visits take place at the doctor’s office.

Pre-eclampsia occurs, when substances are released from the placenta into the bloodstream of the mother, and they affect the kidneys. If the condition progresses to eclampsia, it can lead to kidney damage and seizures, and the outcome will be fatal.
For a long time it was a puzzle to physicians, why some women would show pre-eclamptic symptoms and others would remain problem-free.
New research on patients’ medical history from the John Radcliffe Hospital, Department of Obstetrics and Gynecology in Oxford, Great Britain has been able to point out predisposing risks for pre-eclampsia in pregnant women.

A family history and history of previous eclampsia increases the risk, but also certain health problems make it more likely that pre-eclampsia will occur in the later stages of pregnancy: diabetes mellitus, kidney disease and high blood pressure are medical conditions that increase the risk. Beside these health conditions an increased body mass index at the start of pregnancy can be a predisposing factor, and a high maternal age-women over 40 years of age- are more likely to have the complication of pre-eclampsia. It is obvious that the risk gets higher, if several of these predisposing factors are present. The highest risk is found in women with a rare inherited variation of lupus, called anti-phospholipid syndrome, where blood clots are a problem and pre-eclampsia is a high risk with pregnancy.

Risk Factors For Pre-Eclampsia According To Meta Analysis (published
in the Brit.Med.Journal, March 12, 2005)

Pre-eclampsia Risks

Explanation of independent risk factors: A= Previous History Of Pre-eclampsia; B= In Women With Anti-Phospholipid Antibodies; C= Pre-existing Diabetes; D= Twin Pregnancy; E= First Child; F= Family History; G= High Blood Pressure; H= High Body Mass Index;
I= Maternal Age 40 or more

While it is absolutely imperative that regular pre-natal checks are part of proper health care, there are other consequences. There would be reason to be especially watchful with predisposing conditions. Last not least, prevention also has its place.

It is important that health concerns are already addressed as part of planning for a healthy pregnancy. Avoidance of alcohol and quit smoking are of extreme importance, followed by achieving a normal weight. Good eating habits are needed throughout the entire pregnancy. Opting for pregnancy after age 40 seems trendy in some celebrity circles, but with the knowledge of risk factors, it should be looked at with caution. Nature equipped the human species to have children in the age of 20 to 30, and even though a forty year old may have a youthful appearance, the genetic material is aged, and the biological clock cannot be fooled. Prevention also means that any health condition like preexisting diabetes should be well controlled before a pregnancy.
With a proactive and common-sense approach pre-eclampsia can be either avoided or recognized and treated early, resulting in healthy outcome for mother and baby.

CRP Test Better Than Cholesterol Test

At the 75th Annual Scientific sessions of the American Heart Association in Chicago several presentations centered around the use of the C-reactive protein test to evaluate risks for heart attacks, strokes and the risk of restenosing after doing a cardiac procedure to reopen stenosed coronary arteries.

I have previously reported about the use of the C-reactive protein (CRP) test in a review regarding Dr. Paul Ridker’s study in the New England Journal of Medicine.

This study is ongoing and is known under the name “Women’s Health Study”. He followed a large group of women and found that an increase of the CRP was closely associated with heart attacks. Other investigators found now that an increase of CRP is closely linked with obesity, with the metabolic syndrome (also known under “insulin resistance”) and hormone replacement therapy.

There appears to be a pivotal shift among cardiologists in that it is now clear that inflammation seems to be at the center of the process of hardening of the arteries, not just in a few cases, but in everybody who has heart disease.  Below I  summarized some of the features of CRP in a table.

C-reactive protein (CRP) and risk for heart disease
Facts: Comments:
CRP is produced by the endothelial cells that line the arteries CRP is intimately involved with arteriosclerosis. It has been identified as the culprit, which produces hardening of the arteries together with LDL cholesterol
CRP interferes with nitric oxide release from the endothelial cells, which is required for normal function this leads to a dysfunction of the lining of the arteries, atheromatous plaque formation and it stimulates scavenger cells, called macrophages, to take up LDL. CRP also causes plaque destabilization and clotting
these factors elevate CRP: obesity, the metabolic syndrome, hormone replacement in menopause with artificial hormones, but NOT with bio-identical hormones
these factors lower CRP: low carbohydrate diet, exercise, statins, rosiglitazone (Avandia), lowering of insulin

There will be a lot of information coming out in the next few years. Two major trials have been started where patients with a normal cholesterol, but an abnormally high CRP, will be followed along.

The JUPITER trial will look at the effect of treating these patients with rosuvastatin (brand name: Crestor). About 15,000 patients will be enrolled in this trial and followed for about 4 years. The Canadian 4R trial (Risk Reduction with Ramipril in patients with high CRP) uses ramipril (brand name: Altace) for 12 weeks to see whether it reduces CRP levels. Much more research is needed, but the doctors already know enough about CRP to state that it is a major player when it comes to hardening of arteries. They also know that LDL cholesterol is not outdated, as both LDL cholesterol and CRP play important roles in this process.

Based on a cardiology update in the Medical Post, Dec. 31, 2002, page 17 to 19.

Comments on Dec. 10, 2012: The 4 R Canadian study showed a tendency towards a lowering of CRP with Ramipril, but it was statistically not significant due to numbers that were too low and the observation period was not long enough. The Jupiter trial had to be abandoned after two years as there was concern of diabetes being caused by Crestor and because the effect of prevention of heart attacks was not seen early enough (the number of treatments required before a beneficial effect could be seen was too high). Here is a review why  rosuvastatin (brand name: Crestor) should be approached with caution.

Deliveries Of Male Infants Mean More Complications

A recent article in the British Journal of Medicine on Jan. 18, 2003 (BMJ 2003;326:137) is about a retrospective risk analysis of two groups of full-term delivered newborns that were delivered at a Dublin (Ireland) University Hospital. The delivery records of 4070 male and 4005 female newborns between 1997 and 2000 were analyzed. Dr. Maeve A. Eogan said that the team noted significantly more Cesarean section rates due to more frequent fetal distress in males. There were more forceps deliveries with males and drugs to induce labor had to be used more often in males as well.

One known factor is the that males have a higher birth weight as well as larger heads compared to their female counterparts. But the investigators are looking for further explanations of why males seem to be more prone to distress during deliveries than females. There may be a genetic component that may also play a role, but more investigations are needed to find out why this would be so. In the meantime doctors have to play it safe and watch both mother and the baby about to be born and make sure that there is a good outcome.

This means monitoring the fetal heart rate to check on the baby and monitoring the mother with regard to progress of labor. In case of problems  it usually means a Cesarean section or induced labor, both of which are procedures that are associated with potentail complications.
