    Abstract: Allolio B, Oremus M, Reincke M, Schaeffer H-J, Winkelmann W, Heck G, Schulte HM. High-dose progesterone infusion in healthy males: evidence against antiglucocorticoid activity of progesterone. Eur J Endocrinol 1995;133:696–700. ISSN 0804–4643 High concentrations of unbound cortisol in late pregnancy have been explained by the antiglucocorticoid activity of high progesterone levels. To further test this hypothesis we studied the effect of high-dose progesterone on baseline and corticotrophin-releasing hormone (CRH)-induced hormone secretion in humans. In a double-blind crossover study eight healthy male volunteers received either progesterone (0.714 mg · kg −1 · h −1 for 60 min followed by a dose of 0.45 mg · kg −1 · h −1 over a total infusion time of 315 min) or vehicle as a continuous intravenous infusion. At 210 min a CRH test (0.1 μg/kg body weight as bolus iv) was performed. Within 30 min after the start of progesterone administration the serum progesterone level increased to 454 ± 31 nmol/l and remained in the range of third trimester pregnancy concentrations throughout the infusion period. During vehicle infusion the progesterone level remained in the normal range for healthy males and demonstrated a small but significant increase after CRH (1.52 ± 0.23 vs 0.74 ± 0.14 nmol/l; p 〈 0.01). However, baseline and CRH-stimulated serum cortisol and plasma adrenocorticotrophic hormone remained unaffected by high-dose progesterone. Moreover, unbound salivary cortisol also was not affected by progesterone, suggesting that there is no significant competition for transcortin binding sites. In conclusion, no antiglucorticoid activity was found after short-term administration of progesterone in males. These findings cast doubts on the concept that the alterations of the pituitary–adrenal axis in late pregnancy are induced by the antiglucocorticoid activity of high progesterone concentrations.

    Abstract: Acromegaly is a rare and challenging disease calling for management in highly specialised multidisciplinary teams (MDTs). Untreated disease has severe morbidity and a clearly increased mortality. Major attainments have been gained over the latest decades, and therefore, the aim of this review is to discuss recent achievements in modern multimodal therapy of acromegaly performed by MDTs, with an emphasis on an individualised, proactive management from the time of diagnosis to long-term outcome. Treatment by surgery is the only potential curative treatment, however, even with modern techniques still with modest cure rates, leaving the patients to often long-term medical treatment. Treatment strategies have changed dramatically in the Western world over recent years, implying a more proactive treatment algorithm often with a shorter or longer pre-surgical treatment period with somatostatin receptor ligands (SRLs). Not all patients will however respond to primary treatment with conventional SRLs and there has recently been a development of potential biomarkers for response that has been implemented in the clinical routine. By today, multimodal treatment can bring every patient in remission, but still almost a third of all patients are undertreated according to large, international registries. On the other hand, it might be a challenge not to over treat thereby bringing the patient into a state of relative or absolute growth hormone deficiency. Clinical series published during the last decade on treatment of patients with acromegaly have indicated a normalisation of mortality, most probably reflecting the proactive and individualised modern treatment. In conclusion, modern, multimodal treatment seems to have normalised mortality, but still the patients suffer from a high multi-organ morbidity and often multi-pharmacy. Every patient should receive an individualised, proactive treatment in order to improve long-term outcome and to reduce costs for the society.

    Abstract: Bone turnover is increased in acromegaly. Despite normalization of bone turnover after treatment, the risk for vertebral fractures remains increased. Gonadal status, but not BMD, is correlated with vertebral fractures. Trabecular bone score (TBS) is related to bone microarchitecture. Objective The aim of this study is to assess the longitudinal change in TBS and BMD following treatment for acromegaly. Design, Setting, Patients, Interventions, and Main outcome measures This longitudinal study included 48 patients with acromegaly between 2005 and 2015. BMD, TBS, and markers for bone turnover (P1NP and CTX-1) were measured at baseline and following treatment. Results Following treatment, the mean TBS decreased by 3.0 (±7.0) %, whereas the BMD at the lumbar spine (LS) increased by 3.2 (±4.9) % (both P 〈 0.01). The changes in BMD LS and TBS were not correlated ( P =0.87). The TBS change was found to be −4.5 % (±6.7; P =0.003) in men and −0.3 % (±6.8; P =0.85) in women ( P =0.063 for interaction men vs women). The mean BMD LS increased in men +4.2 g/cm 2 (±4.3; P 〈 0.001), but not in women +1.5 g/cm 2 (±5.6; P =0.36); ( P =0.073 for interaction). BMD increased in the ultradistal radius and total body (both P 〈 0.01). The increase in BMD LS was associated with a decrease in P1NP and CTX-1 ( P 〈 0.001) and with lower P1NP and CTX-1 at the follow-up ( P 〈 0.02). Conclusion Treatment of acromegaly affects TBS and BMD at LS in different manners. The reduction of bone turnover markers predicts the increase in BMD but not the decrease in TBS. The DXA changes were more pronounced in men. Alterations in trabecular bone architecture may explain the persistent fracture risk despite the increase in BMD after disease control.

    Abstract: We report the identification of a number of mutations that result in amino acid replacements (and their phenotypic characterization) in either the MogA-like domain or domains 2 and 3 of the MoeA-like region of the Aspergillus nidulans cnxE gene. These domains are functionally required since mutations that result in amino acid substitutions in any one domain lead to the loss or to a substantial reduction in all three identified molybdoenzyme activities (i.e., nitrate reductase, xanthine dehydrogenase, and nicotinate hydroxylase). Certain cnxE mutants that show partial growth with nitrate as the nitrogen source in contrast do not grow on hypoxanthine or nicotinate. Complementation between mutants carrying lesions in the MogA-like domain or the MoeA-like region, respectively, most likely occurs at the protein level. A homology model of CnxE based on the dimeric structure of E. coli MoeA is presented and the position of inactivating mutations (due to amino acid replacements) in the MoeA-like functional region of the CnxE protein is mapped to this model. Finally, the activity of nicotinate hydroxylase, unlike that of nitrate reductase and xanthine dehydrogenase, is not restored in cnxE mutants grown in the presence of excess molybdate.
