Emergence of De Novo Conditions Following Remission of Cushing Syndrome: A Case Report and Scoping Review.

OBJECTIVE: Onset and exacerbation of autoimmune, inflammatory or steroid-responsive conditions have been reported following the remission of Cushing syndrome, leading to challenges in distinguishing a new condition versus expected symptomatology following remission. We describe a case of a 42-year-old man presenting with new-onset sarcoidosis diagnosed 12 months following the surgical cure of Cushing syndrome and synthesise existing literature reporting on de novo conditions presenting after Cushing syndrome remission. METHODS: A scoping review was conducted in Medline, Epub, Ovid and PubMed. Case reports and case series detailing adult patients presenting with new-onset conditions following Cushing syndrome remission were included. RESULTS: In total, 1641 articles were screened, 138 full-text studies were assessed for eligibility, and 43 studies were included, of which 84 cases (including our case) were identified. Most patients were female (85.7%), and the median reported age was 39.5 years old (IQR = 13). Thyroid diseases were the most commonly reported conditions (48.8%), followed by sarcoidosis (15.5%). Psoriasis, lymphocytic hypophysitis, idiopathic intracranial hypertension, multiple sclerosis, rheumatoid arthritis, lupus and seronegative arthritis were reported in more than one case. The median duration between Cushing remission and de novo condition diagnosis was 4.1 months (IQR = 3.75). Of those patients, 59.5% were receiving corticosteroid therapy at the time of onset. CONCLUSION: Our scoping review identified several cases of de novo conditions emerging following the remission of Cushing syndrome. They occurred mostly in women and within the year following remission. Clinicians should remain aware that new symptoms, particularly in the first year following the treatment of Cushing syndrome, may be manifestations of a wide range of conditions aside from adrenal insufficiency or glucocorticoid withdrawal syndrome.

The effect of ASA, ticagrelor, and heparin in ST-segment myocardial infarction patients with prolonged transport times to primary percutaneous intervention.

OBJECTIVES: To investigate the effects of early upstream antithrombotic therapy administration (ATTA) in ST-segment elevation myocardial infarction (STEMI) patients with prolonged transport times to primary percutaneous intervention (PPCI) on major clinical outcomes. BACKGROUND: It remains unclear whether early upstream administration of aspirin, ticagrelor, and unfractionated heparin (UFH) confers additional benefits compared with in-hospital administration. METHODS: Between 2015 and 2018, we performed PPCI in 709 included consecutive STEMI patients. We compared 482 STEMI patients who received aspirin, ticagrelor, and UFH loading in a non-PCI capable spoke hospital before transfer (NPHT) versus 227 prehospital triage setting (PTS) STEMI patients who received in-ambulance aspirin, followed by ticagrelor and UFH in the hub catheterization laboratory. The primary outcome was the presence of a pre-PPCI TIMI flow 2-3 in the infarct related artery (IRA). The secondary outcomes included definite acute stent thrombosis and hemorrhagic complications. RESULTS: The median times from ticagrelor and heparin administration to angiography in the NPHT group and the PTS group were 80.5 min (Interquartile Range (IQR) 68.5-94) and 10 min (IQR 5-15) respectively (p < .0001). Using inverse probability of treatment weighting to minimize heterogeneity between groups, we showed significant differences for the primary outcome (44.6 versus 18.5%, p < .0001) and for definite acute stent thrombosis (0.6 versus 2.6%, p = .03), with no difference in the combined in-hospital BARC 2-5 bleeding events (1.9 versus 3.5%, p = .18) in the NPHT versus the PTS group, respectively. CONCLUSION: In this single-center retrospective cohort study, after adjusting for baseline covariates, early upstream ATTA with aspirin, ticagrelor, and UFH was associated with greater pre-PPCI TIMI flow and less definite acute stent thrombosis in STEMI patients, without increased bleeding risk.
