Thiazolidinediones may cause fluid retention through proposed mechanism of increasing reabsorption in the collecting duct of the kidney and increasing vascular permeability in adipose tissue. Bile acid sequestrants work in the intestine to bind bile acids which doesn’t affect fluid retention. GLP-1 receptor agonists work to activate these receptors to secrete insulin from beta pancreatic cells/decrease glucagon secretion/ increase satiety and doesn’t affect fluid retention. SGLT2 inhibitors actually cause increase of fluid elimination through the kidneys. Alpha-glucosidase inhibitors work in the gut to decrease carb absorption/digestion and have no affect on fluid retention.

Metformin should be stopped when eGFR falls below 30. This is the only cutoff that is recommended for absolute discontinuing. If the eGFR falls between 30-44 while ontherapy, benefits and risks of discontinuing should be evaluated. New initiation is only recommended when eGFR >45.

Primary treatment for stenotrophomonas maltophilia is SMX-TMP. Meropenem, ciprofloxacin, Ampicillin and vancomycin have no coverage.
