- OBJECTIVES: To examine the risk of developing adrenal carcinomas and clinically overt hypersecreting tumours during short-term follow-up in patients with adrenal incidentalomas. DESIGN: 229 (98 males and 131 females) patients with adrenal incidentalomas were investigated in a prospective follow-up study (median time 25 months; range 3-108 months). The patients were registered between January 1996 and July 2001 and followed until December 2004. Twenty-seven Swedish hospitals contributed with follow-up results. METHODS: Diagnostic procedures were undertaken according to a protocol including reinvestigation with computed tomography scans after 3-6 months, 15-18 months and 27-30 months, as well as hormonal evaluation at baseline and after 27-30 months of follow-up. Operation was recommended when the incidentaloma size increased or if there was a suspicion of a hypersecreting tumour. RESULTS: The median age at diagnosis of the 229 patients included in the follow-up study was 64 years (range 28-84 years) and the median size of the adrenal incidentalomas when discovered was 2.5 cm (range 1-8 cm). During the follow-up period, an increase in incidentaloma size of > or =0.5 cm was reported in 17 (7.4%) and of > or =1.0 cm was reported in 12 (5.2%) of the 229 patients. A decrease in size was seen in 12 patients (5.2%). A hypersecreting tumour was found in 2% of the hormonally investigated patients: Cushing's syndrome (n = 2) and phaeochromocytoma (n = 1). Eleven patients underwent adrenalectomy, but no cases of primary adrenal malignancy were observed. CONCLUSIONS: Patients with adrenal incidentaloma had a low risk of developing malignancy or hormonal hypersecretion during a short-term follow-up period.

- Objectives: To assess effects of GH replacement therapy on cardiac structure and function, exercise capacity as well as serum lipids in elderly patients with GH deficiency (GHD). Patients and methods: Thirty-one patients (six females, 25 males), aged 60–79 years (mean 68 years) with GHD on stable cortisone and thyroxine substitution were studied. All men with gonadotropin deficiency had testosterone and one woman had oestrogen replacement. They were randomized in a double-blind manner to GH or placebo treatment for 6 months, followed by another 12 months GH (Humatrope, Eli Lilly & Co, Uppsala, Sweden). GH dose was 0·017 mg/kg/week for 1 month and then 0·033 mg/kg/week divided into daily subcutaneous injections at bedtime. Echocardiography, exercise capacity tests and serum lipid measurements were performed at 0, 6, 12 and 18 months. Results: During the 6-month placebo-controlled period there were no significant changes in the placebo group, but in the GH-treated group there was a significant increase in IGF-I to normal levels for age, with median IGF-I from 6·9 to 18·5 nmol/l, increase in resting heart rate and maximal working capacity. During the open GH study, IGF-I increased from 8·7 to 19·2 nmol/l at 6 months and 18·8 nmol/l at 12 months (P ≤ 0·001). At 6 months, in the open GH study group, a minor decrease in aortic outflow tract integral (VTI) from 21·8 to 20·7 cm (P = 0·031) and an increase in heart rate at rest from 63 to 67 bpm (P = 0·017), heart rate at maximum exercise from 138 to 144 bpm (P = 0·005) and maximum load at exercise from 142 to 151 Watts (P = 0·014) were seen. These changes were temporary and returned at 12 months with no significant difference from baseline values. Left ventricular dimensions and blood pressure showed no significant changes. At 6 months, in the open GH study group, there was a significant decrease in serum low-density lipoprotein (LDL) cholesterol from 3·7 to 3·4 mmol/l (P = 0·006), a decrease in LDL/HDL ratio from 3·4 to 3·1 (P = 0·036) and a decrease in serum total cholesterol from 5·6 to 5·3 mmol/l (P = 0·036). At 12 months, serum lipids showed same changes with a significant decrease in serum LDL cholesterol (P = 0·0008), in LDL/HDL ratio (P = 0·0005) and in serum total cholesterol (P = 0·049). Serum HDL cholesterol showed no significant change at 6 months, at 12 months a significant increase was seen from 1·2 to 1·4 mmol/l (P = 0·007). There were no significant changes in serum triglycerides. Conclusions: GH substitution to elderly patients with GHD caused only a transient increase in heart rate. At the end of the 12 months there were no significant changes on cardiac noninvasive structural and functional parameters. Maximal working capacity transiently improved. Thus, the therapy was safe without negative effects on cardiac structural and functional noninvasive parameters. Lipid profiles improved with reduction of serum LDL cholesterol accompanied by significant improvement of LDL/HDL ratio and serum HDL cholesterol after 12 months treatment.

- OBJECTIVE: The aim of this study was to determine bone mineral density (BMD), markers of bone metabolism, fractures, and steroids reflecting hormonal control in adult males with congenital adrenal hyperplasia (CAH). SUBJECTS, METHODS AND DESIGN: We compared CAH males with 21-hydroxylase deficiency (n=30), 19-67 years old, with age- and sex-matched controls (n=32). Subgroups of CYP21A2 genotypes, age, glucocorticoid preparation, poor control versus overtreatment, and early versus late (>36 months) diagnosis were studied. Bone mineral density (BMD) measured by dual-energy x-ray absorptiometry (DXA) and markers of bone metabolism and androgens/17-hydroxyprogesterone levels were investigated. RESULTS: All, including older (>30 yrs), CAH patients had lower BMD in all measured sites compared to control subjects. The null group demonstrated lower BMD in more locations than the other groups. Osteoporosis/osteopenia was present in 81% of CAH patients compared to 32% in controls (≥30 yrs). Fracture frequency was similar, osteocalcin lower, and fewer patients than controls had vitamin D insufficiency. IGF-I was elevated in the milder genotypes. In patients, total body BMD was positively correlated to weight, BMI, total lean body mass, triglycerides, and negatively to prolactin. Patients on prednisolone had lower BMD and osteocalcin levels than those on hydrocortisone/cortisone acetate. Patients with poor control had higher femoral neck BMD. There were no differences in BMD between patients with an early versus late diagnosis. CONCLUSIONS: CAH males have low BMD and bone formation markers. BMD should be monitored, adequate prophylaxis and treatment established, and glucocorticoid doses optimized to minimize the risk of future fractures.

- Objective: Life-long glucocorticoid therapy in patients with congenital adrenal hyperplasia (CAH) or the disease per se may result in increased cardiovascular risk. We therefore investigated cardiovascular and metabolic risk profiles in adult CAH males. Subjects and Methods: We compared CAH males (n=30), 19-67 years old, with age- and sex-matched controls (n=32). Subgroups of different ages (<30 years or older) and CYP21A2 genotypes (null, I2splice and I172N as the mildest mutation) were studied. Anthropometry, fat and lean mass measured by dual-energy x-ray absorptiometry (DXA), lipids, liver function tests, homocysteine, lipoprotein(a), glucose and insulin during an oral glucose tolerance test (OGTT), urine albumin, adrenal hormones, and 24h ambulatory blood pressure measurements were studied. Results: CAH males were shorter. Waist/hip ratio and fat mass were higher in older patients and the I172N group. Heart rate was faster in older patients, the I2splice, and I172N groups. Insulin levels were increased during OGTT in all patients and in the I172N group. Gamma-glutamyl transpeptidase was increased in older patients and in the I172N group. Testosterone was lower in older patients. Homocysteine was lower in younger patients which may be cardioprotective. The cardiovascular risk seemed higher with hydrocortisone/cortisone acetate compared to prednisolone. Urinary epinephrine was lower in all groups of patients except in I172N. Conclusions: Indications of increased risk were found in CAH males ≥30 years old and in the I172N group. In contrast, younger CAH males did not differ from age-matched controls. This is likely to reflect a better management in recent years.

- Objective: Fertility in males with congenital adrenal hyperplasia (CAH) is reported from normal to severely impaired. We therefore investigated fertility/fecundity, social/sexual situation, and pituitary- gonadal function in CAH males.Subjects and methods: The patient cohort comprised 30 males with 21-hydroxylase deficiency, 19-67 yr. Their fertility was compared with age-matched national population data. For the evaluation of social/sexual factors and hormone status, age-matched controls were recruited (n=32). Subgroups of different ages (<30 years and older) and CYP21A2 genotypes: null (severe salt wasting), I2splice (milder salt wasting), and I172N (simple virilizing) were also studied. Patients underwent testicular ultrasound examination (n=21), and semen analysis (n=14).Results: Fertility was impaired in CAH males compared to national data (0.9±1.3 vs. 1.8±0.5 children/father, P<0.001). There were no major differences in social and sexual factors between patients and controls apart from more fecundity problems, particularly in the I172N group. The patients had lower testosterone/estradiol ratio and inhibin B, and higher FSH. The semen samples were pathological in 43% (6/14) of patients and sperm concentration correlated with inhibin B and FSH. Testicular adrenal rest tumours (TARTs) were found in 86% (18/21). Functional testicular volume correlated positively with the testosterone/estradiol ratio, sperm concentration and inhibin B. Patients with pathological semen had increased fat mass and indications of increased cardiometabolic risk.Conclusions: Fertility/fecundity was impaired in CAH males. The frequent occurrence of TARTs resulting in testicular insufficiency appears to be the major cause, but other factors such as elevated fat mass may contribute to a low semen quality.

- The aims were assessing liver function tests (LFT) in women with congenital adrenal hyperplasia (CAH) on glucocorticoids. Sixty-one women with genetically verified CAH due to 21-hydroxylase deficiency, aged 18-63 years were compared to 61 controls. Serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase (GGT), anthropometry and fat mass (dual energy X-ray absorptiometry) were measured. ALT and GGT were higher in the entire patient group (p=0.01 and 0.002); AST, GGT and ALP in patients > or =30 years (p=0.007-0.045); all LFT in salt-wasting (p<0.001-0.042); GGT in simple virilizing (p=0.008); ALT, GGT and ALP in Null/Null genotype (p=0.018-0.040); ALT and GGT in I2splice genotype (p<0.001 and 0.011). Using a recently proposed cut-off level for ALT (>0.317 microkat/L), 54% of patients vs 23% of controls had elevated levels (p=0.028). In patients, GGT and ALP correlated with waist circumference and with total body and trunk fat (r=0.274-0.406, p=0.001-0.043). However, ALT, GGT and ALP were increased even in non-obese patients (waist circumference < or =88 cm and body mass index <30 kg/m(2)) (p=0.012-0.045) mainly attributed to the patients > or =30 years who also demonstrated elevated insulin levels and HOMA-indices. In conclusion, compared with controls, women with CAH have higher LFT, in particular patients > or =30 years and those with severe forms, probably reflecting a higher lifetime glucocorticoid exposure. LFT were positively correlated to measurements of body fat. These women might have increased frequency of NAFLD. The finding of higher LFT also in non-obese patients suggests that not only central obesity but also glucocorticoids per se may influence.

- CONTEXT: The chronic, often supraphysiological glucocorticoid doses used in congenital adrenal hyperplasia (CAH) might increase morbidity in cardiovascular disease and diabetes. OBJECTIVE: Our aim was to assess risk factors for cardiovascular disease and diabetes in CAH women. SUBJECTS, METHODS, AND DESIGN: We compared 61 women, 18-63 yr, with CAH due to 21-hydroxylase deficiency with 61 age- and sex- matched controls. Twenty-seven were younger than 30 yr, and 34 were 30 yr or older. Anthropometry, fat and lean mass measured by dual-energy x-ray absorptiometry, serum lipids, insulin, and adrenocortical steroids were studied. MAIN OUTCOME MEASURE: Body composition and cardiovascular risk factors were the main outcome measures. RESULTS: Younger patients and controls had similar waist to hip ratio, lean and fat mass, and insulin. Older patients had higher waist to hip ratio, lean mass, and insulin than controls. Fat mass was similar to controls but higher than in younger patients. Lipid profiles were slightly more favorable in older patients than controls. Gestational diabetes was more common in patients (21% of pregnancies vs. 0, P < 0.026). Few older patients had hypertension, cardiovascular disease, or diabetes. Despite moderate glucocorticoid doses, most patients had suppressed androgens. CONCLUSIONS: No clear evidence of unfavorable cardiovascular risk factors were found. Increased fat mass and higher insulin levels were, however, found in patients older than 30 yr. High frequency of gestational diabetes is a risk marker for future diabetes. Lifelong follow-up, lifestyle modifications, and attempts to adjust and reduce the glucocorticoid doses seem important.

- To determine quality of life (QoL) in adult males with congenital adrenal hyperplasia (CAH). CAH males with 21-hydroxylase deficiency (n = 30), 19-67 years old, were compared with controls (n = 32). QoL was assessed using questionnaires on general living conditions and sexual issues, and the psychological well-being index (PGWB) form. Fewer CAH males than controls were students (3 vs. 25 %, P = 0.028) and more had blue-collar work (57 vs. 33 %, P = 0.023). Patients were less interested in sports (47 vs. 72 %, P = 0.034) and art/literature/film (10 vs. 47 %, P = 0.004). PGWB total score was 82.7 ± 13.7 versus 87.0 ± 11.1 (P = NS), but hydrocortisone/cortisone acetate treated scored lower than controls and prednisolone treated. Glucocorticoid over-treated had lower QoL than those with poor control (PGWB total score 77.1 ± 13.5 vs. 92.4 ± 11.1, P = 0.026) and controls (P = 0.025). Total PGWB score was positively correlated with adrenal androgens and steroid precursors. Subscale scores indicated that patients with late diagnosis were more depressive (12.1 ± 2.8 vs. 13.9 ± 1.4, P = 0.011) and had a lower self-control (11.3 ± 3.6 vs. 13.1 ± 1.0, P = 0.019) compared with controls. Sexual satisfaction was similar in spite of more patients being sexually inactive (27 vs. 6 %, P = 0.040). Adult CAH males differed from controls with respect to type of occupation and spare time interests but had similar QoL despite being less sexually active. Optimizing glucocorticoid therapy might further improve QoL. Some disadvantages found in patients diagnosed late will hopefully not be seen in patients diagnosed by neonatal screening, but this has yet to be studied.

- CONTEXT: Gender-atypical behavior has been described in young girls as well as in women with congenital adrenal hyperplasia (CAH) due to a CYP21A2 deficiency. OBJECTIVE: The aim of the study was to assess health-related, psychosexual, and psychosocial parameters and correlate the results to CYP21A2 genotype. DESIGN AND PARTICIPANTS: Sixty-two Swedish women with CAH and age-matched controls completed a 120-item questionnaire and a validated quality of life instrument [psychological general well-being (PGWB) formula] to identify psychosexual and psychosocial parameters. The patients were divided into four CYP21A2 genotype groups. RESULTS: The women with CAH held more male-dominant occupations (30%) compared to controls (13%) (P = 0.04), especially those in the null genotype group (55%) (P = 0.006). They also reported a greater interest in rough sports (74%) compared to controls (50%) (P = 0.007). Eight women with CAH (14%) reported a prime interest in motor vehicles, compared to none of the controls (P = 0.002). Non-heterosexual orientation was reported by 19% of women with CAH (P = 0.005), 50% in the null genotype group (P = 0.0001), 30% in I2 splice (NS), and 5% in I172N (NS). PGWB total score did not differ between patients and controls. CONCLUSION: We identified increased gender-atypical behavior in women with CAH that could be correlated to the CYP21A2 genotype. This speaks in favor of dose-dependent effects of prenatal androgens on the development of higher brain functions. The impact of the disease on upbringing and interpersonal relationships did not correlate with disease severity, indicating that other factors, such as coping strategies, are important for psychosocial adaptation. This illustrates the need for psychological support to parents and patients.
