Daily PrEP is safe for the kidneys


Jim Allen:
I would say that it's not an unexpected result but good they checked, and an interesting read for those interested. in full:

In short:

--- Quote ---According to a recent study, oral PrEP has a very good renal safety profile even after two years of use. The study also shows that on-demand PrEP has less impact on kidney function than daily PrEP, although this difference is not clinically significant.

Of the 1,253 participants, 40% were daily PrEP users, 39% were on-demand PrEP users and 21% switched regimens. Participants were mostly (98%) men who have sex with men and European (85%), with a median age of 34.

The sample’s median eGFR at baseline was 104 (interquartile range 92 – 114). There were 43% of participants who had baseline risk factors for kidney dysfunction: age over 40 and/or a baseline eGFR below 90 mL/min/1.73 m2. 

As seen in previous studies, eGFR dropped in the first three months after starting PrEP but increased gradually until month 24, whatever the PrEP regimen.

It is worth noting that over a median of 22 months of follow-up, only five PrEP users, evenly distributed between the groups, experienced an eGFR reduction of over 25%. Only two participants stopped PrEP because of a decrease in eGFR and both restarted it later without problems.
