Diuretic pills not recommended for preventing pre-eclampsia

24.01.2007
Although they were prescribed widely in the 1960s to women looking to avoid dangerously high blood pressure during pregnancy, diuretic drugs should not be recommended as a way to prevent this serious condition, called preeclampsia, according to a recent review of studies.

Women who took diuretics -- commonly known as "water pills" -- during pregnancy were not any less likely to develop preeclampsia, to deliver prematurely or to lose their babies than those who did not take the pills, said obstetrician David Churchill of New Cross Hospital in West Midlands, England, and colleagues.

However, women who took diuretics were significantly more likely to have nausea and vomiting.

"From this review, no clear benefits have been found from the use of diuretics to prevent preeclampsia," Churchill said.

The review included five studies and 1,836 women.

The review appears in the latest issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.

Women with preeclampsia, usually diagnosed after 20 weeks of pregnancy, have high blood pressure and protein in their urine. The condition can be dangerous for both mother and fetus, causing pregnancy complications, early delivery and even death.

"Currently, the only cure for the disease is delivery of the baby and the placenta, but this leads to many babies being born prematurely and vulnerable," Churchill said.

For this reason, doctors have focused on diet changes, such as prescribing more calcium-rich foods and other treatments that may prevent the condition before it appears, rather than searching for ways to lessen its effects, said Lisa Bodnar, Ph.D., a maternal nutrition specialist at the University of Pittsburgh.

"There are no changes that a woman can make that will lessen symptoms or 'cure' her disease once she has overt preeclampsia. The dietary modifications that women should make are in early pregnancy, or even before a woman gets pregnant," Bodnar said.

Researchers and doctors originally prescribed diuretics to prevent preeclampsia because they thought the condition was caused by excess salt and water retained by pregnant women. Diuretics increase urination and remove water and salt from the body that can cause serious symptoms in liver, kidney and heart disease, including high blood pressure.

However, doctors stopped recommending diuretics as a regular preventive measure in the 1980s when studies began to link the pills with a decrease in pregnant women's plasma levels, the liquid part of blood that carries blood cells. Plasma levels normally increase as part of a healthy pregnancy.

Diuretics are still prescribed to pregnant women, although less than they used to be.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
