3-Hydroxyisobutyryl-CoA hydrolase deficiency in an Iranian child with novel HIBCH compound heterozygous mutations

We report a patient presenting with developmental delay, Leigh-like abnormalities on MRI and elevated 3-hydroxyisovaleric acid levels. Upon whole-exome sequencing, he was diagnosed with 3-hydroxyisobutyryl-CoA hydrolase (HIBCH) deficiency, and hence subjected to specific dietary treatment. HIBCH deficiency should be considered in the differential diagnosis of Leigh-like disease and/or organic aciduria. © 2019 The Authors. Clinical Case Reports published by John Wiley & Sons Ltd

Coronary artery plaque progression and cardiovascular risk scores in men with and without HIV-infection

ObjectiveThe aim of this study was to assess the association of cardiovascular disease (CVD) risk scores and coronary artery plaque (CAP) progression in HIV-infected participants.MethodsWe studied men with and without HIV-infection enrolled in the Multicenter AIDS Cohort Study (MACS) CVD study. CAP at baseline and follow-up was assessed with cardiac computed tomography angiography (CCTA). We examined the association between baseline risk scores including pooled cohort equation (PCE), Framingham risk score (FRS), and Data collect of Adverse effects of anti-HIV drugs equation (D:A:D) and CAP progression.ResultsWe studied 495 men (211 HIV-uninfected, 284 HIV-infected). The adjusted odds ratio (aOR) of total plaque volume (TPV) and noncalcified plaque volume (NCPV) progression in the highest relative to lowest tertile was 9.4 [95% confidence interval (95% CI) 2.4-12.1, P < 0.001)] and 7.7 (95% CI 3.1-19.1, P < 0.001) times greater, respectively, among HIV-uninfected men in the PCE atherosclerotic cardiovascular disease (ASCVD) high vs. low-risk category. Among HIV-infected men, the association for TPV and NCPV progression for the same PCE risk categories, odds ratio (OR) 2.8 (95% CI 1.4-5.8, P < 0.01) and OR 2.4 (95% CI 1.2-4.8, P < 0.05), respectively (P values for interaction by HIV = 0.02 and 0.08, respectively). Similar results were seen for the FRS risk scores. Among HIV-uninfected men, PCE high risk category identified the highest proportion of men with plaque progression in the highest tertile, although in HIV-infected men, high-risk category by D:A:D identified the greatest percentage of men with plaque progression albeit with lower specificity than FRS and PCE.ConclusionPCE and FRS categories predict CAP progression better in HIV-uninfected than in HIV-infected men. Improved CVD risk scores are needed to identify high-risk HIV-infected men for more aggressive CVD risk prevention strategies
