Serous retinopathy is a complication of lupus nephritis and may mimic HCQ retinopathy. - Dr M Petri on ophthalmology may be too quick to blame eye diseases on HCQ. #CCRW26

Petri recc that we pay attention to the 3 things that increases organ same and SLE death: 1. Disease activity 2. Steroids 3. Comordities #CCRW26

Protocol kidney biopsy at 1 year may be helpful to see if pts are in remission. As pts in complete renal response (CRR) may have active LN - M Petri #CCRW26

Non LN on renal biopsies will show CKD. Modify risks with RAASi, SGLT2i/GLP1i - M Petri #CCRW26

From AMP study, 71% SLE pts with microalbuminuria had LN, almost half of these have “actionable” LN… meaning you should treat. - M Petri #CCRW26

“Microalbuminuria is bad.” It increases mortality, esp for men and increases MACE. Lupus nephritis doubles the risk of mortality. - M Petri #CCRW26

If a patient’s HCQ level is persistently low despite adherence verification, see if it is taking the med with a binder (eg magnesium, antacids)- have them take HCQ separate from other med/supplements - M Petri Pearls #CCRW26

Petri Pearls Part 3 1. “Lupus nephritis is like voting in Chicago” Treat it early and often. 2. 3rd leading cause of deaths is Infection. Pls #vaccinate. Vaccines do not cause SLE or Lupus flares. #CCRW26 @RheumNow

12. ACEi/ARBs are protective against venous thrombosis (low dose ASA does not reduce risk for thrombosis)

13. CV events occur in the first 2 years of diagnosis 14. ILD in SLE is rare (no need to screen, can wait until they have symptoms) 15. “Even first month matters” when it comes to prednisone. 20 mg/d for more than 1 month increase risk of AVN. Risk of depression later
