TPO antibody status prior to first radioactive iodine therapy as a predictive parameter for hypothyroidism in Graves' disease.

Objective: We investigated whether a positive thyroid peroxidase antibody (TPO Ab) status before radioactive iodine (RAI) therapy in patients with Graves' hyperthyroidism is a predictive factor for developing hypothyroidism post RAI. Methods: We performed a retrospective study of patients with Graves' hyperthyroidism with known TPO Ab status, receiving the first administration of RAI. Patients from four thyroid outpatient centres in Belgium receiving their first RAI therapy between the years 2011 and 2019 were studied. Clinical, laboratory, imaging, and treatment data were recorded from medical charts. Hypothyroidism and cure (defined as combined hypo- and euthyroidism) were evaluated in period 1 (≥2 and ≤9 months, closest to 6 months post RAI) and period 2 (>9 months and ≤24 months post RAI, closest to 12 months post RAI). Results: A total of 152 patients were included of which 105 (69%) were TPO Ab-positive. Compared to TPO Ab-negative patients, TPO Ab-positive patients were younger, had a larger thyroid gland, and had more previous episodes of hyperthyroidism. In period 1, 89% of the TPO Ab-positive group developed hypothyroidism and 72% in the TPO Ab-negative group (P = 0.007). In period 2, the observation was similar: 88% vs 72% (P = 0.019). In the multivariate logistic regression analysis, a positive TPO Ab status was associated with hypothyroidism in period 2 (adjusted OR: 4.78; 95% CI: 1.27-20.18; P = 0.024). In period 1, the aOR was 4.16 (95% CI: 1.0-18.83; P = 0.052). Conclusion: A positive TPO Ab status in patients with Graves' hyperthyroidism receiving the first administration of RAI is associated with a higher risk of early hypothyroidism.

Belgian data of ODYSSEY APPRISE: stringent LDL-c targets are in reach when using all available tools.

BACKGROUND: As lipid targets became more stringent in the latest ESC/EAS guidelines, many patients on statin monotherapy are left above their risk-based target, increasing the need for lipid-lowering therapies. The results of the ODYSSEY APPRISE study were recently published by Gaudet et al In this trial, alirocumab (a PCSK9 inhibitor) was investigated in high cardiovascular risk patients in a real-life setting. OBJECTIVE: We aim at analysing the characteristics, safety and efficacy of alirocumab in the Belgian population of the ODYSSEY APPRISE trial and, based on literature research, we aim to evaluate the importance and the need for the add-on, non-statin lipid-lowering therapy in clinical practice. METHODS AND RESULTS: ODYSSEY APPRISE is a multicentric, prospective, single-arm, Phase 3b open-label trial. A total of 68 Belgian patients were enrolled, 63 patients had heterozygous familial hypercholesterolaemia (HeFH). Baseline mean LDL-c was 188.7 mg/dL (SD ± 51.8). At week 12, 65 patients had an evaluable efficacy end point with a mean LDL-c reduction of 59.9% from baseline. The overall incidence of treatment-emergent adverse events (TEAEs) was 75.0%. The most frequent TEAE was back pain (10.3%), nasopharyngitis (10.3%) and injection site erythema (8.8%). Based on the literature, a majority of patients do not reach their risk-based lipid target despite statin therapy alone. CONCLUSION: In a real-life setting, alirocumab is both well-tolerated, safe and very effective in reducing LDL-c in this Belgian cohort. In clinical practice, more patients should be initiated on the add-on, non-statin lipid-lowering therapy in order to reach their risk-based lipid target.

Sarcoidosis presenting as cardiac tamponade: a case report.

A 62-year-old man without medical history presented with a cardiac tamponade due to a voluminous sterile hemorrhagic exudate. Hypermetabolic mediastinal lymph nodes were found on a PET-CT and pathological analysis revealed non-necrotizing granulomatous adenitis, a finding compatible with sarcoidosis. Steroids were started with rapid clinical improvement and complete resolution of the pericardial effusion.Although pericardial effusions are occasionally seen in cardiac sarcoidosis, symptomatic pericardial involvement with evolution to a tamponade is rare. Our patient is the 7th described case of a sarcoidosis presenting as a tamponade.
