ABSTRACT

We investigated the factors associated with serum muscle enzyme elevation in patients with Sheehan's syndrome. A total of 48 patients who were newly diagnosed with Sheehan's syndrome were included and divided into 3 groups: Group 1, creatine kinase (CK) ≥ 1000 U/L; Group 2, 140 < CK < 1000 U/L; and Group 3, CK ≤ 140 U/L. Differences in serum muscle enzymes, serum electrolytes, blood glucose and hormones were compared among the 3 groups. A Spearman correlation analysis and multiple linear regression analysis were performed on serum muscle enzymes and the other variables. Four patients in Group 1 underwent electromyography. Fourteen, 26 and 8 patients were divided into Group 1, Group 2, and Group 3, respectively. The levels of plasma osmolality, serum sodium, free triiodothyronine (FT3) and free thyroxine (FT4) in Group 1 were lower than those in Group 3 at admission (P < .05). There were significant differences in CK, CK-MB, aspartate aminotransferase, lactate dehydrogenase, and alpha-hydroxybutyrate dehydrogenase among the three groups (P < .05). CK was correlated with serum sodium (r = -0.642, P < .001), serum potassium (r = -0.29, P = .046), plasma osmolality (r = -0.65, P < .001), FT3 (r = -0.363, P = .012), and FT4 (r = -0.450, P = .002). Moreover, creatine kinase isoenzyme-MB (CK-MB) was correlated with serum sodium (r = -0.464, P = .001) and plasma osmolality (r = -0.483, P < .001). The multiple linear regression showed that serum sodium was independently and negatively correlated with CK (r = -0.352, P = .021). The electromyogram results supported the existence of myogenic injury. Sheehan's syndrome is prone to be complicated by nontraumatic rhabdomyolysis, with both a chronic course and acute exacerbation. Serum muscle enzymes should be routinely measured. For patients with CK levels > 1000 U/L, a CK-MB/CK ratio < 6% can be a simple indicator to differentiate rhabdomyolysis from acute myocardial infarction. Abnormal serum muscle enzymes observed in Sheehan's syndrome may be associated with hypothyroidism and with hyponatremia in particular.

ABSTRACT

This review aimed to evaluate the level of fatigue in adults with type 2 diabetes measured by the validated Diabetes Symptom Checklist (DSC)and related factors. Ten studies were included. Both DSC (n = 4) and the revised (n = 6) have been used to measure fatigue. When the latter was used (n = 1082), the pooled level of fatigue was 1.77 (on a 0-5 scale). When the former was used (n = 674), the pooled level of fatigue was 1.73 (on a 0-10 scale). Participant demographics (e.g., gender), health information (e.g., BMI), and diabetes-specific factors (e.g., A1C and diabetes distress) were associated with fatigue. Fatigue was negatively related to self-care behaviors. The prevalence of significant fatigue remains unclear due to a lack of a cut-off point of the instrument. Future research is warranted to identify the threshold for clinically significant fatigue and investigate the causal relationship. Nurses are recommended to perform a routine assessment of fatigue.
