T1 - Adrenal Cortical Insufficiency-a Life Threatening Illness With Multiple Etiologies JF - Deutsches Ärzteblatt International N2 - Background: The clinical signs of adrenal cortical insufficiency (incidence, ca. 25 per million per year; prevalence, ca. 400 per million) are nonspecific, and misdiagnoses are therefore common. Glucocorticoid substitution therapy has been in use for 50 years but is not a wholly adequate treatment. Our understanding of this disease remains incomplete in many ways. Methods: We selectively searched the Medline database for publications on adrenal cortical insufficiency, with particular attention to studies from the year 2000 onward (search terms: "adrenal insufficiency" or "Addison's disease" or "hypopituitarism"). Results: Hydrocortisone substitution therapy is often given in doses of 10-25 mg/day, timed according to the circadian rhythm. Gastrointestinal and other, febrile infections account for 30-50% of life-threatening adrenocortical crises. Such crises affect 8 of 100 persons with adrenal cortical insufficiency per year and must be treated by the immediate administration of glucocorticoids and fluids. When persons with adrenal cortical insufficiency are acutely ill or are otherwise under unusual stress, they may need additional amounts of hydrocortisone, often in the range of 5-10 mg but occasionally as high as 200 mg. The sustained administration of excessive amounts of steroid can shorten patients' lives by several years. Inappropriate substitution therapy can cause other major medical conditions, such as metabolic syndrome and osteoporosis. Conclusion: Important measures for the prevention of adrenocortical crises include improved care by treating physicians, education of patients and their families, the provision of emergency identifying documents, and the prescription of glucocorticoid emergency kits.

Often, the physicians who first treat patients with ACC have no prior experience with the disease. The aim of our study was to evaluate the quality of medical care for patients with ACC in Germany. Methods: Data from the German ACC registry were analyzed with regard to the patients’ preoperative diagnostic evaluation, histopathological reporting, and clinical followup. The findings were compared with the recommendations of the European Network for the Study of Adrenal Tumors (ENSAT). Results: Data were analyzed from 387 patients who had been given an initial diagnosis of ACC in the years 1998 to 2009. 21% of them underwent no hormonal evaluation before surgery, and 59% underwent an inadequate hormonal evaluation. This exposed the patients to unnecessary perioperative risks and impaired their follow-up. 48% did not undergo CT scanning of the chest, even though the lungs are the most frequent site of metastases of ACC. For 13% of the patients, the diagnosis of ACC was later revised by a reference pathologist. For 11% of the patients, the histopathology report contained no information about resection status, even though this is an important determinant of further treatment and prognosis. Optimal management requires re-staging at three-month intervals, yet some patients underwent re-staging only after a longer delay, or not at all. Conclusion: We have identified significant deficits in the care of patients with ACC in Germany. We suspect that the situation is similar for other rare diseases. The prerequisite to better care is close and early cooperation of the treating physicians with specialized centers.

Telomere-related genes, such as TERT and ATRX, have been recently described in PPGL, supporting the association between the activation of immortalization mechanisms and disease progression. However, the contribution of other genes involving telomere preservation machinery has not been previously investigated. In this work, we aimed to analyze the prognostic value of a comprehensive set of genes involved in telomere maintenance. For this study, we collected 165 PPGL samples (97 non-metastatic/63 metastatic), genetically characterized, in which the expression of 29 genes of interest was studied by NGS. Three of the 29 genes studied, TERT, ATRX and NOP10, showed differential expression between metastatic and non-metastatic cases, and alterations in these genes were associated with a shorter time to progression, independent of SDHB-status. We studied telomere length by Q-FISH in patient samples and in an in vitro model. NOP10 overexpressing tumors displayed an intermediate-length telomere phenotype without ALT, and in vitro results suggest that NOP10 has a role in telomerase-dependent telomere maintenance. We also propose the implementation of NOP10 IHC to better stratify PPGL patients.

An unanswered question JF - Journal of Personalized Medicine N2 - A relevant issue on the treatment of adrenocortical carcinoma (ACC) concerns the optimal duration of adjuvant mitotane treatment. We tried to address this question, assessing whether a correlation exists between the duration of adjuvant mitotane treatment and recurrence-free survival (RFS) of patients with ACC. We conducted a multicenter retrospective analysis on 154 ACC patients treated for ≥12 months with adjuvant mitotane after radical surgery and who were free of disease at the mitotane stop. During a median follow-up of 38 months, 19 patients (12.3%) experienced recurrence. We calculated the RFS after mitotane (RFSAM), from the landmark time-point of mitotane discontinuation, to overcome immortal time bias. We found a wide variability in the duration of adjuvant mitotane treatment among different centers and also among patients cared for at the same center, reflecting heterogeneous practice. We did not find any survival advantage in patients treated for longer than 24 months. Moreover, the relationship between treatment duration and the frequency of ACC recurrence was not linear after stratifying our patients in tertiles of length of adjuvant treatment. In conclusion, the present findings do not support the concept that extending adjuvant mitotane treatment over two years is beneficial for ACC patients with low to moderate risk of recurrence.
