Abstract

Background

Because the most suitable management of subclinical Cushing syndrome (SCS, which involves hypersecretion of cortisol without clinically evident disease) still is undefined, the current study aimed to compare retrospectively the outcome for a cohort of patients treated by medical therapy or laparoscopic adrenalectomy (LA).

 

Methods

Over a 12-year period, 47 patients with SCS have been treated by means of LA (19 patients, group A) or medical therapy (28 patients, group B). Group A consisted of 15 women and 4 men with a mean age of 54.8 years. Eight patients had a left adrenal mass, whereas nine had a right adrenal mass, and one patient had bilateral lesion. Group B was composed of 18 women and 10 men with a mean age of 57.8 years. Of these patients, 14 had a left adrenal lesion, 12 had a right adrenal lesion, and 1 had bilateral lesion. The patients were followed up for a mean 4 years (range, 1–11 years) by both an endocrinologist and a surgeon.

 

Results

In group A, hypertension improved for 66.3% of the patients; body mass index (BMI) decreased for 47.4%; and hyperlipidemia based on high-density lypoproteins (HDL) cholesterol, total cholesterol ratio, and triglyceridemic concentration improved for 63.2% of the patients. No changes in bone parameters were seen after surgery in SCS patients with osteoporosis. Some patients in group B, during their long-term medical therapy, experienced worsening hypertension (14.2%), hyperlipidemia (17.8%), and diabetes mellitus (8%).

 

Conclusions

This retrospective study focused on a cohort of patients with SCS. Their medium long-term follow-up evaluation showed that LA is better than medical therapy for treating this condition, especially by reducing the cardiovascular risk (hypertension-hyperlipidemia).

Abstract

Background

Adrenalectomy remains the definitive therapy for most adrenal neoplasms. Introduced in the 1990s, laparoscopic adrenalectomy is reported to have lower associated morbidity and mortality. This study aimed to evaluate national adrenalectomy trends, including major postoperative complications and perioperative mortality.

 

Methods

The Nationwide Inpatient Sample was queried to identify all adrenalectomies performed during 1998–2006. Univariate and multivariate logistic regression were performed, with adjustments for patient age, sex, comorbidities, indication, year of surgery, laparoscopy, hospital teaching status, and hospital volume. Annual incidence, major in-hospital postoperative complications, and in-hospital mortality were evaluated.

 

Results

Using weighted national estimate, 40,363 patients with a mean age of 54 years were identified. Men made up 40% of these patients, and 77% of the patients were white. The majority of adrenalectomies (83%) were performed for benign disease. The annual volume of adrenalectomies increased from 3,241 in 1998 to 5,323 in 2006 (p < 0.0001, trend analysis). The overall in-hospital mortality was 1.1%, with no significant change. Advanced age (<45 years as the referent; ≥65 years: adjusted odds ratio [AOR], 4.10; 95%; confidence Interval [CI], 1.66–10.10) and patient comorbidities (Charlson score 0 as the referent; Charlson score ≥2: AOR, 4.33; 96% CI, 2.34–8.02) were independent predictors of in-hospital mortality. Indication, year, hospital teaching status, and hospital volume did not independently affect perioperative mortality. Major postoperative in-hospital complications occurred in 7.2% of the cohort, with a significant increasing trend (1998–2000 [5.9%] vs 2004–2006 [8.1%]; p < 0.0001, trend analysis). Patient comorbidities (Charlson score 0 as the referent; Charlson score ≥2: AOR, 4.77; 95% CI, 3.71–6.14), recent year of surgery (1998–2000 as the referent; 2004–2006: AOR, 1.40; 95% CI, 1.09–1.78), and benign disease (malignant disease as the referent; benign disease: AOR, 1.98; 95% CI, 1.55–2.53) were predictive of major postoperative complications at multivariable analyses, whereas laparoscopy was protective (no laparoscopy as the referent; laparoscopy: AOR, 0.62; 95% CI, 0.47–0.82).

 

Conclusion

Adrenalectomy is increasingly performed nationwide for both benign and malignant indications. In this study, whereas perioperative mortality remained low, major postoperative complications increased significantly.

Long-term unemployment associated with poorer health

Patients with long-term chronic conditions, such as Cushing’s disease or Klinefelter’s syndrome, appear to be at increased risk for long-term unemployment related to their disease.

 

Researchers compared unemployment rates with re-employment rates for 130 patients (81 women) aged 65 years or younger with Addison’s disease, Cushing’s disease, craniopharyngioma or Klinefelter’s syndrome. The researchers presented the results at the Annual Society for Endocrinology BES 2010 in Manchester, England.

 

Based on telephone questionnaires, 83 patients (63.8%) were employed at the time of diagnosis. However, 79 patients (60.8%) were later unemployed, related to their long-term chronic condition.

 

Seventy-seven patients (59.2%) reported being satisfied with their current working status and ability to work. Among those unemployed, nine of 53 patients (40.8%) said they would like to work but did not feel supported.

 

Although the study was small and did not include all chronic endocrine conditions, the researchers said data show a high rate of unemployment for this patient population.

 

“Long-term unemployment is a significant problem for people with chronic diseases,” John Wass, MD, professor of endocrinology at Oxford University and consultant endocrinologist at Oxford Radcliffe Hospitals, said in a press release. “More people should consider returning to work following diagnosis, and more doctors need to encourage and support their patients in this. While a return to work may not be suitable for all patients, it can significantly improve their well-being and quality of life.”
