Ibuprofen’s Anti-androgenic Effect May Result in Hypogonadism in Males

PNAS reports use of ibuprofen by males may result in antiandrogen effects that may contribute to adult male reproductive problems.

Young men exposed to ibuprofen show changes of “compensated hypogonadism," a condition usually seen among elderly men and associated with reproductive and physical disorders. In the men, luteinizing hormone (LH) and ibuprofen plasma levels were positively correlated, and the testosterone/LH ratio decreased.

Researchers used a combination of a randomized, controlled clinical trial and ex vivo and in vitro approaches, and found a univocal depression of testicular function, including testosterone production, after use of over-the-counter ibuprofen.

Also, ibuprofen use results in selective transcriptional repression of endocrine cells in the human testis. This repression results in the elevation of the stimulatory pituitary hormones, resulting in a state of compensated hypogonadism.

Thes findings show ibuprofen alters the endocrine system via selective transcriptional repression in the human testes, thereby inducing compensated hypogonadism.

Musculoskeletal Events with Statin Use

Analysis of the FDA Adverse Event Reporting System data examined the association between statins' musculoskeletal adverse events (MAEs).

Review of the data shows that atorvastatin and rosuvastatin (with strong low‐density lipoprotein cholesterol‐lowering effects) had a higher risk and a faster onset of MAEs when compared with simvastatin.

They could not detect whether concomitant drugs shifted the onset timing of MAEs.

JAMA has published a large Canadian claims-based study showing that nonsteroidal anti-inflammatory drug (NSAID) use in patients with hypertension, heart failure, or chronic kidney disease was not associated with a significant safety risk - but this only looked at short-term outcomes (7-37 days of exposure). 

Update on Checkpoint Inhibitor Safety

“Autoimmunity is the Achilles heel of onco-immunotherapy” per Dr. Leonard Calabrese, which leaves a dilemma for rheumatologists. Onco-immunotherapy induces immune dysregulation to allow patients to develop an immune response to their cancer cells. An unfortunate side effect for patients taking onco-immunotherapy is often autoimmune-like diseases referred to as immune adverse reactions (irAEs). Studies in France and the United States have shown that irAEs can be a good prognostic sign, suggesting these therapies are working. Rheumatology is faced with new problems as onco-immunotherapies may induce new chronic diseases in multiple different forms secondary to the treatment.
