ADIPONECTIN LEVELS IN GRAVES' DISEASE - SYSTEMATIC REVIEW AND META-ANALYSIS

Context

Graves' disease is the most prevalent cause of hyperthyroidism worldwide. Adiponectin, the most abundant adipokine, plays a significant role in a cluster of prevalent diseases connected to metabolic disorders.

Objective

Although the association between adiponectin and Graves' disease has been studied, the existing data is inconsistent. Therefore, we conducted this systematic review and meta-analysis to evaluate the relationship between adiponectin levels and Graves' disease.

Methods

We performed a systematic electronic search on PubMed, EMBASE, Scopus and Cochrane Library using predefined keywords. We used the NHLBI quality assessment tools to assess the included studies.

Results

There were 11 studies involving 781 subjects included in our qualitative synthesis, while 6 studies were included in our quantitative synthesis. We observed significantly increased adiponectin levels in Graves' disease patients compared to controls (MD 2.983 [95% CI 0.138-5.828]) and hypothyroidism patients (MD 3.389 [95% CI 1.332-5.446]). Nevertheless, no significant MD was observed when comparing Graves' disease patients with and without Graves' ophthalmopathy (MD -27.124 [95% CI -88.893 - 34.645]).

Conclusions

Adiponectin levels were significantly higher in patients with Graves' disease compared to controls and hypothyroidism patients. However, patients with and without Graves' ophthalmopathy did not present a significant mean difference in adiponectin levels.

Quality of Life in Patients with Acromegaly - A Romanian Single Center Cross-Sectional Study

CONTEXT

Acromegaly, a severe condition characterized by excessive and unmodulated secretion of growth hormone, leads to morphologic disturbances and multisystem complications.

OBJECTIVE

The purpose of this study was to evaluate the quality of life (QOL) in patients with acromegaly compared to matched obese patients.

DESIGN

This was an observational cross-sectional study.

SUBJECTS AND METHODS

We enrolled 49 patients with acromegaly and 49 obese patients. AcroQoL (acromegaly QoL questionnaire) was applied to all patients and IGF-1 (type 1 insulin-like growth factor 1) was measured.

RESULTS

Patients with acromegaly had a worse QoL compared to patients with obesity (score= 77(53-86) vs. 96(90-102), p<0.001). In the group of patients with acromegaly, there was no difference in the QoL regarding the activity of the disease (active, controlled, or cured). Men had a higher AcroQoL score than women (score= 88(55-95) vs. 74(52.75-82), p=0.02), but there was no difference between patients with microadenomas and the ones with macroadenomas (score= 82(66-88.5) vs. 73(55-83), p=0.136). The most frequent complications were cardiovascular complications (81.63%), articular complications (73.46%), dyslipidemia (65.30%) and digestive complications (63.26%).

CONCLUSIONS

Despite complex treatment and hormonal control, the presence of complications reduces the quality of life in patients with acromegaly, even when compared with obese patients.
