Context: Studies find surgery superior to medications in the treatment of primary aldosteronism (PA). It would be ideal to compare surgical and medical therapy in patients with unilateral PA only, who have the option between these treatment modalities. However, this is challenging as most patients with unilateral PA on adrenal vein sampling (AVS) undergo surgery., Objective: To compare outcomes of surgery and medications in patients with confirmed or likely unilateral PA., Design: Retrospective cohort study of 274 patients with PA managed at two referral centres from 2000 to 2019., Patients: 154 patients identified with unilateral PA using AVS and a validated clinical prediction model were treated with surgical (n = 86) or medical (n = 68) therapy., Measurements: Primary outcome was a composite incident cardiovascular event comprising acute myocardial infarction, coronary revascularization, stroke, atrial fibrillation or congestive cardiac failure. Secondary outcomes were clinical and biochemical control., Results: Cardiovascular outcomes were comparable, with the surgery group having an adjusted hazard ratio of 0.93 (95% CI: 0.32-2.67), p = .89. Both treatments improved clinical and biochemical control, but surgery resulted in better systolic blood pressure, 133.0 ± 11.7 mmHg versus 137.9 ± 14.6 mmHg, p = .02, and lower defined daily dosages of antihypertensive medications, 1.0 (IQR 0.0-2.0) versus 2.6 (IQR 0.8-4.3), p < .001. In addition, 12 of 86 patients in the surgery group failed medical therapy before opting for surgery., Conclusion: In patients with unilateral PA who can tolerate medications, medical therapy improves clinical and biochemical control, and may offer similar cardiovascular protection. However, surgery reduces pill burden, may cure hypertension and is recommended for unilateral PA., (© 2020 John Wiley & Sons Ltd.)

Objective: Men with congenital adrenal hyperplasia (CAH) have impaired fertility. We aimed to assess fertility outcomes and the importance of hypogonadotropic hypogonadism, testicular failure and the presence of testicular adrenal rest tumours (TART)., Design: Retrospective analysis of men attending an adult CAH clinic in a tertiary centre., Patients: Fifty men with CAH due to 21 hydroxylase deficiency were identified of whom 35 were salt wasting and 15 were non-salt-wasting., Measurements: Review of fertility history and parameters including luteinizing hormone (LH), follicle-stimulating hormone (FSH), androstenedione, 17-hydroxyprogesterone (17-OHP), semen analysis and the presence of testicular adrenal rest tissue (TART) on ultrasound., Results: TART were detected by ultrasound in 21 (47%), and their presence was associated with an elevated FSH (P = 0·01). Severe oligospermia was present in 11 of 23 (48%), and this was associated with an elevated FSH (P = 0·02), suppressed LH (P < 0·01) and TART (P = 0·03) when compared to those with a sperm count >5 × 10(6) per ml. Of those that desired fertility, 10 of 17 (59%) required treatment intensification and four underwent in vitro fertilization. Intensification resulted in a rise in median LH (0·6-4·3 IU/l; P = 0·01). Live birth rate was 15 of 17 (88%) with a median (range) time to conception of 8 (0-38) months., Conclusions: Suppressed LH is a marker for subfertility and is often reversible. Testicular failure is closely associated with TART formation. If TART are detected, sperm cryopreservation should be offered given the risk of progression to irreversible testicular failure. Male fertility in CAH can be improved by intensified treatment and assisted reproductive technology., (© 2015 John Wiley & Sons Ltd.)
