Rheumatologists' Comments

Jack-just a "heads-up" on chronic hydroxychloroquine use. While serving as in locums hospital attending at Westchester Medical Center recently I became aware of 3-4 cases of biopsy proven cardiomyopathy due to HCQ. Unlike the rare case of acute cardiac toxicity associated with short-term use of HCQ, these were all long-term treatments for "RA" and the patients presented with cardiac decompensation misattributed to ischemic and/or non-ischemic cardiomyopathy. Also note that HCQ toxicity is now more apparent than in the past.("In early toxicity there are no visible signs, but field, OCT and mfERG changes can be detected"). Have a good meeting in Hawaii-David
