Abstract Context Hyperthyroidism is associated with low levels of cholesterol and triglycerides, and hypothyroidism is associated with hypercholesterolemia and hypertriglyceridemia. Objective The aim of this systematic review was to investigate the impact of therapy for overt and subclinical hyper- and hypothyroidism on serum lipids. Data Sources We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Scopus from 1970 through April 5, 2018. Study Selection Pairs of independent reviewers selected randomized and observational studies evaluating lipid parameters in patients undergoing treatment for hyper- or hypothyroidism. Data Extraction Pairs of independent reviewers extracted data and appraised studies. Data Synthesis Treatment of overt hyperthyroidism showed a significant increase in total cholesterol (TC) by 44.50 mg/dL (95% confidence interval [CI]: 37.99, 51.02), low-density lipoprotein cholesterol (LDL-C) by 31.13 mg/dL (95% CI: 24.33, 37.93), high-density lipoprotein cholesterol (HDL-C) by 5.52 mg/dL (95% CI: 1.48, 9.56), apolipoprotein A (Apo A) by 15.6 mg/dL (95% CI: 10.38, 20.81), apolipoprotein B (apo B) by 26.12 mg/dL (95% CI: 22.67, 29.57), and lipoprotein (Lp[a]) by 4.18 mg/dL (95% CI: 1.65, 6.71). There was no significant change in triglyceride (TG) levels. Treatment of subclinical hyperthyroidism did not change any lipid parameters significantly. Levothyroxine therapy in overt hypothyroidism showed a statistically significant decrease in TC by -58.4 mg/dL (95% CI: -64.70, -52.09), LDL-C by -41.11 mg/dL (95% CI: -46.53, -35.69), HDL-C by -4.14 mg/dL (95% CI: -5.67, -2.61), TGs by -7.25 mg/dL (95% CI: -36.63, 17.87), apo A by -12.59 mg/dL (95% CI: -17.98, -7.19), apo B by -33.96 mg/dL (95% CI: 41.14, -26.77), and Lp(a) by -5.6 mg/dL (95% CI: -9.06, -2.14). Levothyroxine therapy in subclinical hypothyroidism showed similar changes but with a smaller magnitude. The studies contained varied population characteristics, severity of thyroid dysfunction, and follow-up duration. Conclusions Treatment of overt but not subclinical hyperthyroidism is associated with worsening of the lipid profile. Levothyroxine therapy in both overt and subclinical hypothyroidism leads to improvement in the lipid profile, with a smaller magnitude of improvement in subclinical hypothyroidism.
MON-164 Determinants of Quality of Life in Primary and Secondary Adrenal Insufficiency from Two Large Tertiary Care Centers in the United States
Abstract Background: Patients with primary adrenal insufficiency (PAI) and secondary adrenal insufficiency (SAI) report impaired quality of life. Predictors of adverse outcomes include duration of disease, supraphysiologic glucocorticoid (GC) use, and presence of other comorbidities. There is limited evidence to suggest that quality of life is disproportionately affected in one subtype of adrenal insufficiency. Objective: To identify determinants of quality of life in patients with PAI vs SAI. Method: Survey study of patients with the diagnosis of AI between 2015 and 2019 was evaluated at two large tertiary medical centers in the United States. Collected variables included data on circumstances of AI diagnosis, symptoms, management, burden of disease, and overall well-being. Patients with AI due to exogenous glucocorticoid use were excluded. Results: Patients with PAI (n=310, 65% women) were diagnosed at a younger age (37 ± 19 vs 48 ± 16 years, p<.01) than patients with SAI (n=255, 57% women). Patients with SAI were more likely not to understand their diagnosis (13% vs 4% in PAI, p<.01), or to report a discordant diagnosis (16% vs 9% in PAI, p=.02). Patients with PAI were on a higher dose of daily GC (23.8 mg vs 18.5 mg hydrocortisone (HC) equivalent, p <.01), with higher number of patients on HC> 25 mg/day (33% vs 15%, p<.01). Patients with PAI reported a higher compliance with wearing medical alert ID (79% vs 64%, p=.01) and higher availability of injectable GC (74% vs 58%, p<.01). Patients with PAI reported a higher frequency of at least one adrenal crisis within the last 12 months that required self- injectable GC (32% vs 16%, p<.01), or prompted ER visits (56% vs 29%, p<.01) compared to those with SAI. Nevertheless, patients with PAI were more likely to report good general health (78% vs 65% in SAI, p<.01). When adjusted for current age, sex, duration of disease, supraphysiologic GC use, number of current symptoms and recent adrenal crises, patients with SAI had HR of 2.6 (CI 95% 1.5-4.3) for poor health, 1.6 (CI 95% 0.95-2.8) for physical limitations, 1.7 (CI 95% 1.1-2.7) for fatigue, and 2.7 (CI 95% 1.5-4.9) for social limitations compared to those with PAI. Conclusions: Patients with PAI receive higher daily GC and experience a higher number of adrenal crises when compared to patients with SAI. However, patients with PAI report a better general perception of health, possibly due to a more robust knowledge of their disease and higher comfort level managing AI. More effort is needed to ensure patients with AI are appropriately educated regarding their medical condition and therapy.
MON-160 The Burdens of Adrenal Insufficiency: A Survey Study from Two Tertiary Care Centers in the United States
Abstract Background: Adrenal insufficiency (AI) is a chronic disorder necessitating life-long replacement. Patients’ quality of life and health outcomes depend on knowledge and comfort level with self-management. Objective: To determine patients’ knowledge in regards to diagnosis and management, estimate burden of disease and to identify predictors of adverse outcomes in patients with AI Methods: Survey study of patients with AI evaluated at two tertiary medical centers between 2015 and 2019. Collected variables included data on circumstances of AI diagnosis, symptoms, management, burden of disease, and overall well-being. Results: Among 785 patients (mean age at diagnosis 44.2 ± 18.0, 64% women, and 92% Caucasian), 310 (40%) had primary AI (PAI), 255 (33%) had secondary AI (SAI) not related to glucocorticoid use, and 211 (27%) had steroid-induced AI (SIAI). Patients were diagnosed with AI after presenting with symptoms for a median of 1 year (0-6), 28% with symptoms lasting >2 years, 44% visiting emergency room (ER) at least once prior to diagnosis. A third of patients reported a discordant diagnosis from their medical record. Baseline glucocorticoid replacement therapy included hydrocortisone (HC) in 447 (59%), median of 20 mg (IQR 15 - 25mg), prednisone in 190 (25%), median of 5 mg (IQR 4 - 7.5mg), other regimens in 38 (5%), and no steroids in the remainder (85, 11%); 197 (26%) patients reported daily equivalent HC dose of >25 mg. Overall, 549 (73%) of patients reported use of stress dose steroids at least once per year, higher in patients taking HC >25 mg/day (3.2 vs 2.7 times per year if HC<25mg/day, p=0.01). Improper use of stress steroids was reported in 193, 25% patients. Patients taking HC>25 mg /day reported a higher number of adrenal crises (1.6 vs 1.3 in patients on HC<25 mg/day, p=0.04). Among 314 (41%) patients who reported ER visits due to adrenal crisis, only a third received prompt glucocorticoids. One third of patients described their general health as fair or poor. Predictors of negative perceptions of overall health included SIAI (OR 6.2 and 2.5, vs PAI and SAI respectively), poor understanding of diagnosis (OR 2.6), daily HC>25 mg (OR 2.1), and presence of at least one adrenal crisis (OR 2.3) (p<0.001 for all). Conclusion: Patients with AI experience delay in diagnosis, and a third do not fully understand their diagnosis. In addition to patient education, interventions to improve general health and outcomes may include selecting a physiological glucocorticoid replacement therapy, prevention of adrenal crisis, and improving ER care.
