Published on Leave a comment on Antibiotics Better Than Ibuprofen For UTI Treatment

The majority of women experience at least one urinary tract infection (UTI) at some point in their life. The normal treatment is antibiotics, but some researchers have questioned whether this is necessary - because some studies found most cases will simply resolve on their own without antibiotic treatment. Another issue is growing antibiotic resistance in treating UTIs - some women try one antibiotic after another in their UTI treatment due to antibiotic resistance.

Recently a study was conducted in 3 Scandinavian countries that looked specifically at this issue: Can uncomplicated UTIs be simply treated with non-prescription ibuprofen (e.g. Advil) or are antibiotics better? Women with UTIs were randomly assigned to a 3 day course of antibiotics (178 women) or a 3 day course of the pain reliever ibuprofen (181 women). They found that 53% of the ibuprofen group recovered without antibiotics (even though it took about 3 days longer than women who received antibiotics). However, seven cases (3.9%) of pyelonephritis occurred in the ibuprofen group, and none in the antibiotic group. Five of these patients were even hospitalized - but all recovered with antibiotics. Pyelonephritis is a kidney infection (the bacteria of the UTI has traveled to the kidneys).

There were no cases of pyelonephritis in the antibiotic group (they took  pivmecillinam). But even with an initial 3 day course of antibiotics - 11.2% of the antibiotic group needed a second course of antibiotics within 1 month to recover. The researchers main conclusions: since we can't tell who will respond well without antibiotics - therefore everyone should take them for a UTI.

My only question is: why not do this same study testing a course of D-mannose vs antibiotics for UTIs? One study found that non-prescription D-mannose to be as effective as antibiotics in treating recurring UTIs. Anecdotal evidence (from women) is that it works especially well for those caused by E. coli (up to 90% of UTIs). And antibiotic resistance will never happen taking it, because it's not an antibiotic. (Post on a mannose product for UTIs in development).  ...continue reading "Antibiotics Better Than Ibuprofen For UTI Treatment"

Published on Leave a comment on Surprising Effect in Men Taking Ibuprofen For Extended Periods

A recent study by a team of researchers from France and Denmark highlighted the point that all medicines have side-effects, even though we may not realize it for years. Ibuprofen is a great non-prescription pain reliever - a nonsteroidal anti-inflammatory drug (NSAID), but it should be taken only when needed. Ibuprofen is found in such commonly used medicines as Advil and Motrin. The researchers found that ibuprofen has antiandrogenic effects (alters or disrupts the endocrine system) which results in a temporary condition called "compensated hypogonadism" when taken for extended periods by healthy young men (in the study 600 mg was taken daily for 6 weeks).

The researchers stress that this "depression of important aspects of testicular function, including testosterone production" was temporary from short term use, but they were concerned with those who take it daily for longer periods, such as athletes. They wondered whether this could be contributing to lowered sperm levels and the drops in male fertility that we are seeing in western developed countries. [Note that ibuprofen use has also been linked to a higher risk of cardiac arrest.] From Medical Xpress:

Taking ibuprofen for long periods found to alter human testicular physiology

A team of researchers from Denmark and France has found that taking regular doses of the pain reliever ibuprofen over a long period of time can lead to a disorder in men called compensated hypogonadism. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study, which involved giving the drug to volunteers and monitoring their hormones and sperm production.

To learn more about the possible impacts of the popular anti-inflammation drug Ibuprofen on male fertility when taken for long periods of time, the researchers asked 31 men between the ages of 18 and 35 to take 600 milligrams (three tablets) a day of the drug for six weeks. Other volunteers were given a placebo. Over the course of the study, the volunteers were tested to see what impact the drug had on their bodies.

The researchers report that just two weeks into the study, they found that all of the volunteers had an increase in luteinizing hormones, which the male body uses to regulate the production of testosterone. The increase indicated that the drug was causing problems in certain cells in the testicles, preventing them from producing testosterone, which is, of course, needed to produce sperm cells. They further report that the change caused the pituitary gland to respond by producing more of another hormone, which forced the body to produce more testosterone. The net result was that overall testosterone levels remained constant, but the body was overstressing to compensate for the detrimental impact of the Ibuprofen—a state called compensated hypogonadism.

The researchers note that while compensated hypogonadism can cause a temporary reduction in the production of sperm cells, reducing fertility, it is generally not cause for alarm. What is more of a concern, they note, is using the drug for longer periods of time. It has not been proven yet, but the researchers suspect such use, as is seen with some professional athletes or others with chronic pain issues, might lead to a condition called overt primary hypogonadism, in which the symptoms become worse—sufferers report a reduction in libido, muscle mass and changes in mood. Additional studies are required, they note, to find out if this is, indeed, the case. [Original study.]

Published on Leave a comment on Ibuprofen Use and Cardiac Arrest Risk?

A new study has been released that reminds us that all drugs (whether prescription or non-prescription) have side-effects.  This time a nation wide study from Denmark found that short-term use of the non-steroidal anti-inflammatory drugs (NSAIDs) ibuprofen (e.g. Advil and Motrin) and diclofenac is linked to a higher risk of cardiac arrest (the heart suddenly stops beating). It was an observational study so can't definitely say that ibuprofen and diclofenac caused the cardiac arrests, but the findings match a growing body of evidence.

Since Ibuprofen and other NSAIDs are popular non-prescription medicines used worldwide, people assume they are safe to use. In Denmark, ibuprofen is the only NSAID sold as an over-the-counter drug, and only in small amounts. In the U.S., both ibuprofen and diclofenac are sold in both non-prescription and prescription forms.

In the study, they found an increased risk of cardiac arrest in ibuprofen and diclofenac users. However, they did not find a risk of cardiac arrest with the use of COX-2 selective inhibitors, rofecoxib and celecoxib, nor with the NSAID naproxen. One of the researchers (Dr. Gislason) therefore advises consumers to try to avoid diclofenac, to limit the use of ibuprofen to no more than 1200 mg per day, and that perhaps the safest is naproxen (up to 500 mg per day). From Medical Xpress:

'Harmless' painkillers associated with increased risk of cardiac arrest

Painkillers considered harmless by the general public are associated with increased risk of cardiac arrest, according to research published today in the March issue of European Heart Journal - Cardiovascular Pharmacotherapy.....The current study investigated the link between NSAID use and cardiac arrest. All patients who had an out-of-hospital cardiac arrest in Denmark between 2001 and 2010 were identified from the nationwide Danish Cardiac Arrest Registry. Data was collected on all redeemed prescriptions for NSAIDs from Danish pharmacies since 1995. These included the non-selective NSAIDs (diclofenac, naproxen, ibuprofen), and COX-2 selective inhibitors (rofecoxib, celecoxib).

A total of 28 947 patients had an out-of-hospital cardiac arrest in Denmark during the ten year period. Of these, 3 376 were treated with an NSAID up to 30 days before the event. Ibuprofen and diclofenac were the most commonly used NSAIDs, making up 51% and 22% of total NSAID use, respectively. Use of any NSAID was associated with a 31% increased risk of cardiac arrest. Diclofenac and ibuprofen were associated with a 50% and 31% increased risk, respectively. Naproxen, celecoxib and rofecoxib were not associated with the occurrence of cardiac arrest, probably due to a low number of events.

"The findings are a stark reminder that NSAIDs are not harmless," said Professor Gislason. "Diclofenac and ibuprofen, both commonly used drugs, were associated with significantly increased risk of cardiac arrest. NSAIDs should be used with caution and for a valid indication. They should probably be avoided in patients with cardiovascular disease or many cardiovascular risk factors." NSAIDs exert numerous effects on the cardiovascular system which could explain the link with cardiac arrest. These include influencing platelet aggregation and causing blood clots, causing the arteries to constrict, increasing fluid retention, and raising blood pressure. [Original study.]
