RESUMEN

BACKGROUND: No randomised controlled trial has ever been done in patients with metastatic phaeochromocytomas and paragangliomas. Preclinical and first clinical evidence suggested beneficial effects of sunitinib. We aimed to evaluate the safety and efficacy of sunitinib in patients with metastatic phaeochromocytomas and paragangliomas. METHODS: FIRSTMAPPP is a multicentre, international, randomised, placebo-controlled, double-blind, phase 2 trial done at 14 academic centres across four European countries. Eligible participants were adults (aged ≥18 years) with sporadic or inherited progressive metastatic phaeochromocytomas and paragangliomas. Patients were randomly assigned (1:1) to receive either oral sunitinib (37·5 mg per day) or placebo. Randomisation was stratified according to SDHB status (mutation present vs wild type) and number of previous systemic therapies (0 vs ≥1). Primary endpoint was the rate of progression-free survival at 12 months according to real-time central review (Response Evaluation Criteria in Solid Tumours version 1.1). On the basis of a two-step Simon model, we aimed for the accrual of 78 patients, assuming a 20% improvement of the 12-month progression-free survival rate from 20% to 40%, to conclude that sunitinib is effective. Crossover from the placebo group was allowed. This trial is registered with ClinicalTrials.gov, number NCT01371201, and is closed for enrolment. FINDINGS: From Dec 1, 2011, to Jan 31, 2019, a total of 78 patients with progressive metastatic phaeochromocytomas and paragangliomas were enrolled (39 patients per group). 25 (32%) of 78 patients had germline SDHx variants and 54 (69%) had used previous therapies. The primary endpoint was met, with a 12-month progression-free survival in 14 of 39 patients (36% [90% CI 23-50]) in the sunitinib group. In the placebo group, the 12-month progression-free survival in seven of 39 patients was 19% (90% CI 11-31), validating the hypotheses of our study design. The most frequent grade 3 or 4 adverse events were asthenia (seven [18%] of 39 and one [3%] of 39), hypertension (five [13%] and four [10%]), and back or bone pain (one [3%] and three [8%]) in the sunitinib and placebo groups, respectively. Three deaths occurred in the sunitinib group: these deaths were due to respiratory insufficiency, amyotrophic lateral sclerosis, and rectal bleeding. Only the latter event was considered drug related. Two deaths occurred in the placebo group due to aspiration pneumonia and septic shock. INTERPRETATION: This first randomised trial supports the use of sunitinib as the medical option with the highest level of evidence for anti-tumour efficacy in progressive metastatic phaeochromocytomas and paragangliomas. FUNDING: French Ministry of Health, through the National Institute for Cancer, German Ministry of Education and Research, and the German Research Foundation within the CRC/Transregio 205/2, EU Seventh Framework Programme, and a private donator grant.

RESUMEN

Based on recent data, a total number of about 29 000 patients with adrenal insufficiency can be calculated for Germany, and about 1500 fatalities due to adrenal crises have to be expected within the next decade. Management of adrenal crises is still unsatisfactory. The objectives of this study were to establish consensus for diagnostic criteria, prevention strategies, and treatment recommendations for adrenal crises. The study was conducted from January 2022 to April 2023, using Delphi technique. Four rounds of questionnaires were sent to 45 experts, selected by a coordinating group on behalf of the adrenal section of the German Society of Endocrinology. The survey was implemented online using the REDCap web application. Responses were captured anonymously. During the Delphi process the expert panel developed diagnostic criteria to identify patients likely to have an adrenal crisis. Education about adrenal insufficiency among patients as well as non-endocrine medical personnel were regarded as highly important. It was suggested that recommendations for the management of adrenal insufficiency have to be simplified and made widely available. This study provides pragmatic strategies to identify and treat patients prone to adrenal crisis, thereby highlighting the need for an improved management of patients with adrenal insufficiency.

RESUMEN

Patients with salt-wasting congenital adrenal hyperplasia (SW-CAH) usually show pronounced impairment of aldosterone secretion and, therefore, also require mineralocorticoid replacement. While a lot of research and discussion focusses on the glucocorticoid therapy in SW-CAH to replace the missing cortisol and to control adrenal androgen excess, very little research is dealing with mineralocorticoid replacement. However, recent data demonstrated an increased cardiovascular risk in adult CAH patients urging to reflect also on the current mineralocorticoid replacement therapy. In this review, we explain the role and function of the mineralocorticoid receptor, its ligands and inhibitors and its relevance for the therapy of patients with SW-CAH. We performed an extensive literature search and present data on mineralocorticoid therapy in SW-CAH patients as well as clinical advice how to monitor and optimise mineralocorticoid replacement therapy.

RESUMEN

BACKGROUND: Appropriate glucocorticoid dose adjustment in specific situations significantly impacts quality of life and performance of patients with adrenal insufficiency. It is also pivotal for the prevention of adrenal crisis. OBJECTIVES: Improving medical care for patients with adrenal insufficiency. MATERIALS AND METHODS: Selective literature research focussing on the most recent studies. RESULTS: Optimal glucocorticoid substitution aims at closely mimicking physiological fluctuations of cortisol levels. In recent years glucocorticoid preparations with modified pharmacokinetics have expanded the therapeutic arsenal. Adrenal crises occur with an incidence of 4.8-9.3 crises per 100 patient years. With a mortality of 0.5 per 100 patient years adrenal crisis is a life-threatening event. Therefore, it is of the utmost importance to adjust glucocorticoid dose in situations with increased cortisol demand in order to prevent as well as appropriately treat adrenal crisis. CONCLUSIONS: To prevent life-threatening adrenal crisis, patients, their families and medical staff require training.

RESUMEN

Familial neurohypophyseal diabetes insipidus (FNDI) is an autosomal dominant hereditary disorder characterized by severe polydipsia and polyuria that usually presents in early childhood. In this study, we describe a new arginine vasopressin (AVP) gene mutation in an ethnic German family with FNDI and provide an overview of disease-associated AVP-gene mutations that are already described in literature. Three members of a German family with neurohypophyseal diabetes insipidus were studied. Isolated DNA from peripheral blood samples was used for mutation analysis by sequencing the whole coding region of AVP-NPII gene. Furthermore, we searched the electronic databases MEDLINE (Pubmed) as well as HGMD, LOVD-ClinVar, db-SNP and genomAD in order to compare our cases to that of other patients with FNDI. Genetic analysis of the patients revealed a novel heterozygote missense mutation in exon 2 of the AVP gene (c.274T>G), which has not yet been described in literature. We identified reports of more than 90 disease-associated mutations in the AVP gene in literature. The novel mutation of the AVP gene seems to cause FNDI in the presented German family. Similar to our newly detected mutation, most mutations causing FNDI are found in exon 2 of the AVP gene coding for neurophysin II. Clinically, it is important to think of FNDI in young children presenting with polydipsia and polyuria.

RESUMEN

BACKGROUND: Patients with adrenal insufficiency (AI) require lifelong glucocorticoid (GC) replacement. AI patients need to adjust GC dosage in response to stressful events and illness in order to prevent life-threatening adrenal crisis (AC). AIM: To evaluate self-management of patients with AI. METHODS: Four German centres, which are using patient's diary as part of their routine clinical practice, instructed AI patients to prospectively document any discomfort, intercurrent illness or stressful events as well as changes in GC therapy on a daily basis. Diaries of 80 patients (44 females, 52.9 ± 15.9 years, 34 primary AI) were collected and analysed. A symptom score sheet was used to evaluate severity of discomfort. RESULTS: In total, 34 074 patient days (93.4 years) were recorded. 4622 days with discomfort were documented. On 35% of those days (n = 1621), patients increased their GC dose (4.8% of all days). Patients who recorded discomfort had a median of four episodes of discomfort, which lasted a median of 2 days. Women documented significantly more episodes of discomfort than men (P = 0.014). Low-to-median symptom scores resulted in GC increase by 50%-60%, whereas high symptom scores and/or fever resulted in doubling GC daily dose. However, dose increase was only 55% in situations indicating gastrointestinal (GI) infection. CONCLUSION: Severe discomfort did not always result in dose increase, especially in GI infection. However, low symptom scores resulted in an inappropriate GC increase in some patients. This underscores an urgent need for improved training methods. Keeping daily records might be a useful tool for continued and individualized patient education.

RESUMEN

Glucocorticoid excess is a known risk factor for non-alcoholic fatty liver disease (NAFLD). Our objective was to analyse the impact of glucocorticoid replacement therapy on the development of NAFLD and NAFLD-related fibrosis and, therefore, on cardiovascular as well as hepatic morbidity in patients with adrenal insufficiency. Two hundred and fifteen individuals with primary (n = 111) or secondary (n = 104) adrenal insufficiency were investigated for hepatic steatosis and fibrosis using the fatty liver index (FLI), NAFLD fibrosis score (NAFLD-FS), Fibrosis-4 Index (FiB-4) plus sonographic transient elastography. Results were correlated with glucocorticoid doses and cardiometabolic risk parameters. The median dose of hydrocortisone equivalent was 20 mg daily, with a median therapy duration of 15 years. The presence and grade of hepatic steatosis and fibrosis were significantly correlated with cardiometabolic risk factors. We could not find any significant correlations between single, daily or cumulative doses of glucocorticoids and the grade of liver steatosis, nor with fibrosis measured via validated sonographic techniques. In patients with adrenal insufficiency, glucocorticoid replacement within a physiological range of 15-25 mg hydrocortisone equivalent per day does not appear to pose an additional risk for the development of NAFLD, subsequent liver fibrosis, or the cardiovascular morbidity associated with these conditions.

RESUMEN

CONTEXT: Patients with endogenous Cushing's syndrome (CS) may suffer from a wide range of neuropsychiatric symptoms leading to impaired quality of life (QoL). OBJECTIVE: Glucocorticoid receptor (GR) polymorphisms are associated with increased (BclI and N363S) or decreased (A3669G and ER22/23EK) GR sensitivity. HYPOTHESIS: GR genotypes may modulate and affect QoL and recovery after remission differently via GR sensitivity. METHODS: 295 patients with endogenous CS (81 active, 214 in remission) from 3 centers of the German Cushing's Registry were included for the cross-sectional analysis. All subjects were assessed with three questionnaires (CushingQoL, Tuebingen CD-25, SF-36). For the longitudinal part, 120 patients of them were analyzed at baseline and after 1.5 ± 0.9 yrs of follow-up. DNA samples were obtained from peripheral blood leukocytes for GR genotyping. RESULTS: Patients in remission scored significantly better than patients with active CS in the CushingQoL questionnaire and in the SF-36 sub-categories physical and social functioning, role-physical, bodily pain, and vitality. In cross-sectional analysis, no differences in QoL between minor allele and wildtype carriers were detected for all polymorphisms in active or cured CS. In longitudinal analysis, however, carriers with BclI minor allele showed significant improvement in SF-36 sub-categories vitality (P = .038) and mental health (P = .013) compared to wildtype carriers (active CS at baseline vs. CS in remission at follow-up). The outcome of the two questionnaires CushingQoL and Tuebingen CD-25 improved significantly in both wildtype and minor allele carriers. CONCLUSION: BclI minor allele carriers initially had the lowest QoL but recovered better from impaired QoL than wildtype carriers.

RESUMEN

OBJECTIVE: This study aimed to investigate the ability of the immune system assessment questionnaire (ISAQ) to predict adrenal crisis (AC) and infectious events in patients with primary adrenal insufficiency (PAI). DESIGN: This was a prospective single-centre study over three years. METHODS: Patients answered the ISAQ at baseline and were seen every 4-6 months in the endocrine outpatient clinic. At each visit previous infectious periods which required an increase in daily glucocorticoid dosage and AC were reported and documented. Seventy-five patients with PAI (53 women; 43 patients with autoimmune PAI, 20 patients with salt-wasting congenital adrenal hyperplasia and 12 patients who underwent bilateral adrenalectomy) were analysed. Due to the COVID-19 pandemic and consecutive lockdown measures, the data were analysed separately for March 2018 to March 2020 (period 1), and March 2020 to March 2021 (period 2). RESULTS: During period 1 the ISAQ score significantly correlated with the number of reported infectious events (r=0.351; p<0.01), but not during period 2 (r=0.059, p=0.613), in which the number of infectious events per patient-year significantly decreased (1.1±0.1 vs 0.4±0.1; p<0.001). The frequency of AC decreased from 8.8 to 2.4 per 100 patient-years between the two study periods. The ISAQ score was not different between patients with or without AC. CONCLUSIONS: The ISAQ score does not identify patients prone to ACs. The COVID-19 pandemic and consecutive lockdown measures significantly diminished the frequency of infectious events and ACs.

RESUMEN

BACKGROUND: Toll-like receptor-4 (TLR4) has been implicated in the pathogenesis of different renal diseases in rodent models. However, in human kidney disease, TLR4 expression and regulation is not well understood. We hypothesized that renal TLR4 expression plays a role in chronic kidney disease (CKD) and is associated with proteinuria, kidney function, histological diagnosis, and inflammatory mediators. METHODS: We quantified TLR4 mRNA as well as expression of macrophage chemoattractant protein-1 (MCP-1), transforming growth factor-ß1 (TGF-ß1) and interleukin-6 (IL-6) in human kidney biopsies from 70 patients with CKD. We measured kidney function, urinary MCP-1 protein excretion, and the amount of chronic damage. Macrophage load was quantified by CD68 and vascularization by CD34 immunostaining. RESULTS: TLR4 expression correlated significantly with MCP-1 and TGF-ß1 expression. High TLR4 expression was associated with high IL-6 expression. TLR4 expression was significantly upregulated in patients with severe proteinuria, and in patients with chronic ischemic renal damage and IgA nephropathy, when compared to patients with thin glomerular basement membrane disease. TLR4 expression did not correlate with creatinine clearance, renal outcome, macrophage load or chronic damage. CONCLUSIONS: We show for the first time that renal TLR4 expression was significantly associated with the pro-inflammatory marker MCP-1 and the profibrotic molecule TGF-ß1 in kidney biopsies from patients with CKD, suggesting that increased expression of TLR4 is an important feature of CKD.

RESUMEN

Adrenal insufficiency (AI) requires life-long treatment with glucocorticoid replacement therapy. Over- or under-substitution carries the risk of increased morbidity in the form of side effects or adrenal crises. Glucocorticoid replacement therapy needs to be flexible with dose adaptation in special situations. This could not be managed by medical personnel on a daily basis, but requires an educated patient who has a good knowledge of the disease, understands his medical therapy and is able to perform situational dose adaptation. The rarity of the disease in combination with the need to respond to stressful situations with rapid glucocorticoid dose adjustment underlines that a well-trained patient is crucial for optimal management of the disease.In this literature review we provide background information further clarifying the need of education in patients with AI including the current shortcomings of medical therapy and of the treatment of patients with AI. We outline the aims of therapeutic patient education, present the concept of structured patient education in Germany, and discuss available results of patient group education programs. Furthermore, we propose strategies how therapeutic patient education for adrenal insufficiency can be organized under COVID-19 pandemic conditions.

RESUMEN

SUMMARY: Apart from adrenal myelolipomas, adrenal lipomatous tumors are rare and only seldom described in the literature. We present the case of a 50-year-old man, with a classical form of congenital adrenal hyperplasia (CAH), which was well treated with prednisolone and fludrocortisone. The patient presented with pollakisuria and shortness of breath while bending over. On MRI, fat-equivalent masses were found in the abdomen (14 × 19 × 11 cm on the right side and 10 × 11 × 6 cm on the left side). The right adrenal mass was resected during open laparotomy and the pathohistological examination revealed the diagnosis of an adrenal lipoma. Symptoms were subdued totally postoperatively. This is the first report of a bilateral adrenal lipoma in a patient with CAH that we are aware of. LEARNING POINTS: Macronodular hyperplasia is common in patients with congenital adrenal hyperplasia (CAH). Solitary adrenal tumors appear in approximately 10% of adult CAH patients and are often benign myelolipomas. The Endocrine Society Clinical Practice Guideline does not recommend routine adrenal imaging in adult CAH patients. Adrenal imaging should be performed in CAH patients with clinical signs for an adrenal or abdominal mass. Adrenal lipoma is rare and histopathological examinations should rule out a differentiated liposarcoma.

RESUMEN

We report on a 25-year-old woman with pronounced generalized lipodystrophy and a progeroid aspect since birth, who also had Marfan syndrome (MFS; fulfilling the Ghent criteria) with mild skeletal features, dilated aortic bulb, dural ectasia, bilateral subluxation of the lens, and severe myopia in addition to the severe generalized lipodystrophy. She lacked insulin resistance, hypertriglyceridemia, hepatic steatosis, and diabetes. Mutation analysis in the gene encoding fibrillin 1 (FBN1) revealed a novel de novo heterozygous deletion, c.8155_8156del2 in exon 64. The severe generalized lipodystrophy in this patient with progeroid features has not previously been described in other patients with MFS and FBN1 mutations. We did not find a mutation in genes known to be associated with congenital lipodystrophy (APGAT2, BSCL2, CAV1, PTRF-CAVIN, PPARG, LMNB2) or with Hutchinson-Gilford progeria (ZMPSTE24, LMNA/C). Other progeria syndromes were considered unlikely because premature greying, hypogonadism, and scleroderma-like skin disease were not present. Our patient shows striking similarity to two patients who have been published in this journal by O'Neill et al. [O'Neill et al. (2007); Am J Med Genet Part A 143A:1421-1430] with the diagnosis of neonatal progeroid syndrome (NPS). This condition also known as Wiedemann-Rautenstrauch syndrome is a rare disorder characterized by accelerated aging and lipodystrophy from birth, poor postnatal weight gain, and characteristic facial features. The course is usually progressive with early lethality. However this entity seems heterogeneous. We suggest that our patient and the two similar cases described before represent a new entity, a subgroup of MFS with overlapping features to NPS syndrome.

RESUMEN

CONTEXT: An important clinical feature of Cushing's syndrome (CS) is proximal muscle myopathy caused by glucocorticoid induced protein metabolism. However, interindividual differences cannot be explained solely by the pure extent of hypercortisolemia. OBJECTIVE: To evaluate the effects of glucocorticoid receptor (GR) polymorphisms (BclI, N363S, ER22/23EK and A3669G), which influence peripheral glucocorticoid sensitivity on muscular function in endogenous CS. METHODS: 205 patients with proven endogenous CS (128 central, 77 adrenal) from 3 centers of the German Cushing's Registry and 125 subjects, in whom CS was ruled out, were included. All subjects were assessed for grip strength (via hand grip dynamometer) and performed a chair-rising test (CRT). DNA samples were obtained from peripheral blood leukocytes for GR genotyping. RESULTS: In patients with active CS, normalized handgrip strength of the dominant and nondominant hand was higher in A3669G minor allele than in wildtype carriers (P = .006 and P = .021, respectively). CS patients in remission and ruled-out CS showed no differences in handgrip strength regarding A3669G minor allele and wildtype carriers. Male CS patients harboring the ER22/23EK wildtype presented lower hand grip strength than minor allele carriers (P = .049 dominant hand; P = .027 nondominant hand). The other polymorphisms did not influence handgrip strength. CRT showed no differences regarding GR polymorphisms carrier status. CONCLUSION: Handgrip strength seems to be more susceptible to hypercortisolism in A3669G wildtype than in A3669G minor allele carriers. This might partially explain the inter-individual differences of glucocorticoid-induced myopathy in patients with endogenous CS. ER22/23EK polymorphism seems to exert sex-specific differences.

RESUMEN

OBJECTIVE: Patients with adrenal insufficiency (AI) suffer from impaired quality of life and are at risk of adrenal crisis (AC) despite established replacement therapy. Patient education is regarded an important measure for prevention of AC and improvement of AI management. A standardized education programme was elaborated for patients with chronic AI in Germany. DESIGN: Longitudinal, prospective, questionnaire-based, multi-centre study. METHODS: During 2-h sessions, patients (n = 526) were provided with basic knowledge on AI, equipped with emergency cards and sets and trained in self-injection of hydrocortisone. To evaluate the education programme, patients from eight certified centres completed questionnaires before, immediately after and 6-9 months after training. RESULTS: 399 completed data sets were available for analysis. Questionnaire score-values were significantly higher after patient education, indicating successful knowledge transfer (baseline: 17 ± 7.1 of a maximum score of 29; after training: 23 ± 4.2; P < 0.001), and remained stable over 6-9 months. Female sex, younger age and primary cause of AI were associated with higher baseline scores; after education, age, cause of AI and previous adrenal crisis had a significant main effect on scores. 91% of patients would dare performing self-injection after training, compared to 68% at baseline. An improvement of subjective well-being through participation in the education programme was indicated by 95% of the patients 6-9 months after participation. CONCLUSION: Patient group education in chronic AI represents a helpful tool for the guidance of patients, their self-assurance and their knowledge on prevention of adrenal crises. Repeated training and adaptation to specific needs, for example, of older patients is needed.

RESUMEN

Mitotane is the only approved drug for advanced adrenocortical carcinoma (ACC) and no biomarkers are available to predict attainment of therapeutic plasma concentrations and clinical response. Aim of the study was to evaluate the suitability of cytochrome P450(CYP)2W1 and CYP2B6 single nucleotide polymorphisms (SNPs) as biomarkers. A multicenter cohort study including 182 ACC patients (F/M = 121/61) treated with mitotane monotherapy after radical resection (group A, n = 103) or in not completely resectable, recurrent or advanced disease (group B, n = 79) was performed. CYP2W1*2, CYP2W1*6, CYP2B6*6 and CYP2B6 rs4803419 were genotyped in germline DNA. Mitotane blood levels were measured regularly. Response to therapy was evaluated as time to progression (TTP) and disease control rate (DCR). Among investigated SNPs, CYP2W1*6 and CYP2B6*6 correlated with mitotane treatment only in group B. Patients with CYP2W1*6 (n = 21) achieved less frequently therapeutic mitotane levels (>14 mg/L) than those with wild type (WT) allele (76.2% vs 51.7%, p = 0.051) and experienced shorter TTP (HR = 2.10, p = 0.019) and lower DCR (chi-square = 6.948, p = 0.008). By contrast, 55% of patients with CYP2B6*6 vs. 28.2% WT (p = 0.016) achieved therapeutic range. Combined, a higher rate of patients with CYP2W1*6WT+CYP2B6*6 (60.6%) achieved mitotane therapeutic range (p = 0.034). In not completely resectable, recurrent or advanced ACC, CYP2W1*6 SNP was associated with a reduced probability to reach mitotane therapeutic range and lower response rates, whereas CYP2B6*6 correlated with higher mitotane levels. The association of these SNPs may predict individual response to mitotane.

RESUMEN

CONTEXT: Appropriate management of adrenal insufficiency (AI) in pregnancy can be challenging due to the rarity of the disease and lack of evidence-based recommendations to guide glucocorticoid and mineralocorticoid dosage adjustment. OBJECTIVE: Multicenter survey on current clinical approaches in managing AI during pregnancy. DESIGN: Retrospective anonymized data collection from 19 international centers from 2013 to 2019. SETTING AND PATIENTS: 128 pregnancies in 113 women with different causes of AI: Addison disease (44%), secondary AI (25%), congenital adrenal hyperplasia (25%), and acquired AI due to bilateral adrenalectomy (6%). RESULTS: Hydrocortisone (HC) was the most commonly used glucocorticoid in 83% (97/117) of pregnancies. Glucocorticoid dosage was increased at any time during pregnancy in 73/128 (57%) of cases. In these cases, the difference in the daily dose of HC equivalent between baseline and the third trimester was 8.6 ± 5.4 (range 1-30) mg. Fludrocortisone dosage was increased in fewer cases (7/54 during the first trimester, 9/64 during the second trimester, and 9/62 cases during the third trimester). Overall, an adrenal crisis was reported in 9/128 (7%) pregnancies. Cesarean section was the most frequent mode of delivery at 58% (69/118). Fetal complications were reported in 3/120 (3%) and minor maternal complications in 15/120 (13%) pregnancies without fatal outcomes. CONCLUSIONS: This survey confirms good maternal and fetal outcome in women with AI managed in specialized endocrine centers. An emphasis on careful endocrine follow-up and repeated patient education is likely to have reduced the risk of adrenal crisis and resulted in positive outcomes.

RESUMEN

BACKGROUND: Cross-sectional imaging regularly results in incidental discovery of adrenal tumours, requiring exclusion of adrenocortical carcinoma (ACC). However, differentiation is hampered by poor specificity of imaging characteristics. We aimed to validate a urine steroid metabolomics approach, using steroid profiling as the diagnostic basis for ACC. METHODS: We did a prospective multicentre study in adult participants (age ≥18 years) with newly diagnosed adrenal masses. We assessed the accuracy of diagnostic imaging strategies based on maximum tumour diameter (≥4 cm vs <4 cm), imaging characteristics (positive vs negative), and urine steroid metabolomics (low, medium, or high risk of ACC), separately and in combination, using a reference standard of histopathology and follow-up investigations. With respect to imaging characteristics, we also assessed the diagnostic utility of increasing the unenhanced CT tumour attenuation threshold from the recommended 10 Hounsfield units (HU) to 20 HU. FINDINGS: Of 2169 participants recruited between Jan 17, 2011, and July 15, 2016, we included 2017 from 14 specialist centres in 11 countries in the final analysis. 98 (4·9%) had histopathologically or clinically and biochemically confirmed ACC. Tumours with diameters of 4 cm or larger were identified in 488 participants (24·2%), including 96 of the 98 with ACC (positive predictive value [PPV] 19·7%, 95% CI 16·2-23·5). For imaging characteristics, increasing the unenhanced CT tumour attenuation threshold to 20 HU from the recommended 10 HU increased specificity for ACC (80·0% [95% CI 77·9-82·0] vs 64·0% [61·4-66.4]) while maintaining sensitivity (99·0% [94·4-100·0] vs 100·0% [96·3-100·0]; PPV 19·7%, 16·3-23·5). A urine steroid metabolomics result indicating high risk of ACC had a PPV of 34·6% (95% CI 28·6-41·0). When the three tests were combined, in the order of tumour diameter, positive imaging characteristics, and urine steroid metabolomics, 106 (5·3%) participants had the result maximum tumour diameter of 4 cm or larger, positive imaging characteristics (with the 20 HU cutoff), and urine steroid metabolomics indicating high risk of ACC, for which the PPV was 76·4% (95% CI 67·2-84·1). 70 (3·5%) were classified as being at moderate risk of ACC and 1841 (91·3%) at low risk (negative predictive value 99·7%, 99·4-100·0). INTERPRETATION: An unenhanced CT tumour attenuation cutoff of 20 HU should replace that of 10 HU for exclusion of ACC. A triple test strategy of tumour diameter, imaging characteristics, and urine steroid metabolomics improves detection of ACC, which could shorten time to surgery for patients with ACC and help to avoid unnecessary surgery in patients with benign tumours.

RESUMEN

CONTEXT: Nonalcoholic fatty liver disease represents the hepatic manifestation of the metabolic syndrome. Nonalcoholic steatohepatitis (NASH) is the progressive form of liver injury. The pathophysiology that leads to NASH is not well understood. OBJECTIVE: We hypothesize that an altered cortisol metabolism in the liver may be a pathogenetic factor. DESIGN AND PATIENTS: 75 patients (28 men, 47 women) underwent liver biopsy for elevation in liver enzymes. Histological diagnosis identified normal liver in eight, fatty liver in 20, NASH grade 1 in 22, grade 2 in nine, grade 3 in three patients, and other forms of hepatitis or cirrhosis in 13 patients. We quantified hepatic 11beta-hydroxysteroid dehydrogenase type1 (11beta-HSD1) and hexose-6-phosphate-dehydrogenase (H6PDH) mRNA expression by real-time PCR. In addition, analysis of 24 h urinary excretion of cortisol metabolites using GCMS was performed and compared with healthy controls. RESULTS: 11beta-HSD1 mRNA expression correlated significantly (R2= 0.809; P < 0.001) with H6PDH mRNA expression, negatively with waist-to-hip ratio in women (R2= 0.394; P= 0.005), but not with urinary (THF + 5alpha-THF)/THE ratio, total cortisol metabolite excretion, age, BMI, degree of fatty liver or NASH stages. Total cortisol metabolite excretion was increased in patients with fatty liver or NASH compared with healthy controls. CONCLUSIONS: Our data suggest that expression of hepatic 11beta-HSD1 and H6PDH are closely interlinked. 11beta-HSD1 gene expression does not seem to be involved in the pathogenesis of fatty liver or NASH. However, those patients showed an increased 5alpha- and 5beta-reduction of cortisol leading to an increased cortisol turnover rate and an activation of the HPA axis.
