Hydroxychloroquine reduces interleukin-6 levels after myocardial infarction : The randomized, double-blind, placebo-controlled OXI pilot trial

Objectives: To determine the anti-inflammatory effect and safety of hydroxychloroquine after acute myocardial infarction. Method: In this multicenter, double-blind, placebo-controlled OXI trial, 125 myocardial infarction patients were randomized at a median of 43 h after hospitalization to receive hydroxychloroquine 300 mg (n = 64) or placebo (n = 61) once daily for 6 months and, followed for an average of 32 months. Laboratory values were measured at baseline, 1, 6, and 12 months. Results: The levels of interleukin-6 (IL-6) were comparable at baseline between study groups (p = 0.18). At six months, the IL-6 levels were lower in the hydroxychloroquine group (p = 0.042, between groups), and in the on-treatment analysis, the difference at this time point was even more pronounced (p = 0.019, respectively). The high-sensitivity C-reactive protein levels did not differ significantly between study groups at any time points. Eleven patients in the hydroxychloroquine group and four in the placebo group had adverse events leading to in-terruption or withdrawal of study medication, none of which was serious (p = 0.10, between groups). Conclusions: In patients with myocardial infarction, hydroxychloroquine reduced IL-6 levels significantly more than did placebo without causing any clinically significant adverse events. A larger randomized clinical trial is warranted to prove the potential ability of hydroxychloroquine to reduce cardiovascular endpoints after myocar-dial infarction. (c) 2021 The Authors.

Manifestations and Outcome of Cardiac Sarcoidosis and Idiopathic Giant Cell Myocarditis by 25-Year Nationwide Cohorts

Background Cardiac sarcoidosis (CS) and giant cell myocarditis (GCM) share many histopathologic and clinical features. Whether they are parts of a one-disease continuum has been discussed.Methods and Results We compared medical record data of 351 CS and 28 GCM cases diagnosed in Finland since the late 1980s and followed until February 2018 for a composite end point of cardiac death, aborted sudden death, and heart transplantation. Heart failure was the presenting manifestation in 50% versus 15% (PP=0.044), of GCM and CS, respectively. At presentation, left ventricular ejection fraction was P=0.004). The median (interquartile range) of plasma NT-proBNP (N-terminal pro-B-type natriuretic peptide) was 5273 (2782-11309) ng/L on admission in GCM versus 859 (290-1950) ng/L in CS (PPPConclusions GCM differs from CS in presenting with more extensive myocardial injury and having worse long-term outcome. Yet the key determinant of prognosis appears to be the extent of myocardial injury rather than the histopathologic diagnosis.</p

PCOS Features and Steroid Profiles Among Young Adult Women with a History of Premature Adrenarche

Context: Premature adrenarche (PA) may increase the risk for polycystic ovary syndrome (PCOS). Objective: To study features of PCOS in young adult women with a history of PA. Methods: Thirty PA and 42 control females were followed from prepuberty to young adulthood (median age 18.1 years).The main outcome measures were ovarian function, the use of contraceptives, and clinical and biochemical indicators of hyperandrogenism. Results: We found no differences in the use of hormonal contraceptives (50 vs 50%, PA vs controls, respectively; P> .999), indication for using contraceptives (P= .193), or in the history of oligo- (17 vs 26%, P= .392) and amenorrhea (0 vs 0%, P> .999). Among women not using hormonal contraceptives, those with a history of PA had a higher prevalence of hirsutism (27 vs 0%, P= .023) but not acne (87 vs 67%, P= .252). Steroid profiles were broadly comparable between the groups, but PA women had lower sex hormone-binding globulin (SHBG) concentrations (30.1 vs 62.4 nmol/L, P< .001) resulting in higher free androgen index (3.94 vs 2.14, P< .001). The difference in SHBG levels persisted through body mass index adjustment. SHBG correlated negatively with the homeostasis model assessment for insulin resistance (r -0.498, P= .003). Anti-Mullerian hormone concentrations were comparable between the groups (39.3 vs 32.1 pmol/L, P= .619). Conclusion: PA was not associated with evident ovarian dysfunction in young adult women. However, women with a history of PA had decreased SHBG levels and thus, increased bioavailability of circulating androgens.Peer reviewe
