Prevalence and predictors of depression and anxiety in adult patients with type 1 diabetes in tertiary care setting.

AIMS: To determine gender and age differences in the prevalence of depression and anxiety and their predictive factors in adult patients with type 1 diabetes (DM1). METHODS: Random sample of DM1 adult patients from a tertiary care hospital cohort. To evaluate the presence of depression and anxiety, psychological evaluation was performed using structured clinical interview (MINI). For the specific evaluation of fear of hypoglycemia (FH), FH-15 questionnaire was used. RESULTS: 339 patients [51.6% male; 38.5 ± 12.9 years; HbA1c 7.5 ± 1.1% (58.5 ± 14.2 mmol/mol); 20.1 ± 12.0 years of DM1] met the inclusion criteria. Prevalence of depression, anxiety, and FH in men vs. women was as follows (%): depression: 15.4 vs. 33.5 (p < 0.05); anxiety: 13.7 vs. 26.2 (p < 0.05); and FH: 42.8 vs. 46.0 (p = NS). Among midlife female patients, prevalence of depression and anxiety was higher compared to male. Moreover, comorbid depressive and anxious symptoms were also higher in midlife female patients compared to age-matched male patients (3.5 vs. 14%, p < 0.05). Apart from age-related vulnerability, female gender, poor glycemic control, and microvascular and macrovascular complications were predictive factors for depressive and anxious symptomatology. Unawareness hypoglycemia and anxiety-prone personality were predictor factors for FH. CONCLUSIONS: In adults with DM1, prevalence of depression and anxiety is higher in women. Midlife patients, in particular women, show a significantly higher prevalence of anxiety symptoms and comorbid depression and anxiety. The presence of secondary complications and sustained poor glycemic control should alert to the possibility of these mental disorders, especially in the most vulnerable age population; clinical, gender and age-related patterns could help to design more effective psychological assessment and support in adult patients with DM1.

Validation of PHPQoL, a Disease-Specific Quality-of-Life Questionnaire for Patients With Primary Hyperparathyroidism.

CONTEXT: Health-related quality of life (HRQoL) is impaired in primary hyperparathyroidism (PHPT) but instruments to specifically assess this are scarce. OBJECTIVE: Validate the new disease-specific Primary Hyperparathyroidism Quality of Life (PHPQoL) questionnaire in usual clinical practice. DESIGN: Observational, prospective, and multicenter. SETTING: Public hospital ambulatory care. PATIENTS: Patients with PHPT of both sexes, aged more than or equal to 18 years either initiated treatment for PHPT (group A) or had stable PHPT, not requiring therapy (group B). Patients in group A had at least one surgical criterion according to the 2009 Third International Workshop on Management of Asymptomatic PHPT. INTERVENTION: Sociodemographic, clinical, and HRQoL data (PHPQol, Short Form-36, Psychological Well-Being Index, and patients' self-perceived health status) were collected. Group A underwent 4 evaluations (baseline, 3 ± 1, 6 ± 1, and 12 ± 2 months after a therapeutic intervention) and group B 2, at baseline and 1 month later to assess test-retest reliability. RESULTS: A total of 182 patients were included (104 group A, 78 group B) with a mean age (SD) of 61.4 (12.1) years; 79.7% were women. Group A increased PHPQoL score (SD) (better HRQoL) (52 ± 23 at baseline; 62 ± 24 at 12 months; P < .001). At baseline, symptomatic patients had a lower PHPQoL score (worse) than asymptomatic ones (51 ± 21 vs 68 ± 21; P < .001). Correlations were seen between PHPQoL and Short Form-36, Psychological Well-Being Index, and self-perceived health status (P < .001). PHPQoL had good internal consistency (Cronbach's α = 0.80), test-retest reliability (group B, intraclass correlation coefficient > 0.80), and sensitivity to detect HQRoL changes over time. CONCLUSIONS: PHPQoL is a valid HRQoL measure to assess the impact of PHPT on health perception in clinical practice.

Early hyponatraemia after pituitary surgery: cerebral salt-wasting syndrome.

Hyponatraemia is a common complication in patients undergoing neurosurgery. It can be caused either by the syndrome of inappropriate secretion of antidiuretic hormone or by the cerebral salt-wasting syndrome (CSWS). CSWS frequently occurs in patients suffering from subarachnoid haemorrhage and brain injury, but it is rare after pituitary tumour surgery. However, this diagnostic possibility should be considered as these disorders require specific treatment and have different prognoses. In this article, we present a case of acute and early hyponatraemia caused by CSWS after pituitary tumour surgery. We also revise the aetiology, mechanisms, differential diagnosis and treatment of hyponatraemia after pituitary surgery.

Variability in the presence of the metabolic syndrome in Type 2 diabetic patients attending a diabetes clinic. Influences of age and gender.

In this study, we have assessed age and gender-related influences on the presence of the metabolic syndrome (MS) and closely related variables in Type 2 diabetic patients attending a diabetes clinic. For this purpose, we have taken retrospective clinical and biochemical data from consecutive Type 2 diabetic patients (n = 291) and we have classified them by gender, age (with 55 and 70 years as cut-off levels) and having or not having the MS (using both the WHO and NCEP-ATP III MS definitions). A higher prevalence of adiposity and hypertension was present in the females. Males were characterized by higher uric acid and lower HDL-cholesterol and apoA(1) levels (two-way ANOVA considering jointly age and gender as main effects, P < 0.05 in every case). Overall the prevalence of NCEP-ATP III-defined MS was less frequent than WHO-defined MS (63.2% versus 81.1%, respectively). This difference was greater for males (42.1% versus 77.6%, respectively) than for females (75.5% versus 83.2% respectively). The kappa-coefficient for the concordance between both MS definitions was 0.46 for males and 0.72 for females in the first age band, 0.29 for males and 0.48 for females in the second age band and 0.24 for males and 0.51 for females in the third age band. Thus, this study reveals relevant differences in the application of WHO and NCEP-ATP III MS definitions in a clinic-based Type 2 diabetic population from Southern Spain. In addition, the data suggest that gender confers a specific influence upon some MS-associated features in Type 2 diabetic patients attending a diabetes clinic irrespective of age band.

Relationships of apolipoprotein B(100) with the metabolic syndrome in Type 2 diabetes mellitus.

The current study assessed whether features of the metabolic syndrome are associated with higher apolipoprotein B(100) (apoB(100)) levels in people with Type 2 diabetes (n = 298) not taking lipid-lowering drugs. Body-mass index (BMI), waist:hip ratio (WHR), urinary albumin excretion rate, presence or absence of hypertension, uric acid levels, and apoB(100) levels were assessed. Both higher BMI and urinary albumin excretion rate were associated with higher apoB(100) levels (1.02 +/- 0.25 ( +/- S.D.) g/l in normal weight, 1.07 +/- 0.22 g/l in overweight and 1.14 +/- 0.25 g/l in obese individuals; P < 0.01; 1.09 +/- 0.23 g/l in normoalbuminuric patients, 1.06 +/- 0.22 g/l if urinary albumin excretion rate 20-50 microg/min and 1.17 +/- 0.27 g/l if urinary albumin excretion rate > 50 microg/min; P < 0.05). An association between the number of features of the metabolic syndrome and higher apoB(100) levels was found (1.03 +/- 0.22 g/l if no features, 1.08 +/- 0.25 g/l if one feature, 1.11 +/- 0.20 g/l if two features and 1.15 +/- 0.27 g/l if > 2 features; P for trend < 0.01). Thus apoB(100) levels show an association with the metabolic syndrome and, hypothetically, to insulin-insensitivity in Type 2 diabetes. BMI (but not WHR) and urinary albumin excretion rate accounted for most of the power of this relationship.

Adding metformin versus insulin dose increase in insulin-treated but poorly controlled Type 2 diabetes mellitus: an open-label randomized trial.

To compare the effect of adding metformin to insulin therapy with a moderate increase in insulin dose alone in insulin-treated, poorly controlled Type 2 diabetic patients, 47 consecutive such patients (baseline daily dose >0.5 IU kg(-1) and HbA1c >8%) were openly randomized either to a combination of their previous insulin schedule plus metformin (2.55 g daily in three divided doses, n = 24) or to a moderate insulin dose increase (20% of baseline, n = 23). The patient status/biochemical profile was assessed at entry and at 4 months. Among those assigned to insulin + metformin, 18 took the drug. Upon an intention-to-treat basis, patients assigned to insulin dose increase had a statistically significant weight gain (1.16+/-1.9 vs 0.3+/-4.5 kg, p < 0.05). Patients assigned to the insulin + metformin regimen experienced a significantly greater fall in HbA1c (-1.87+/-2.16 vs 0.03+/-1.68%, p < 0.01), total cholesterol (-0.56+/-0.89 vs 0.14+/-0.72 mmol l(-1), p < 0.05) and LDL-cholesterol (-0.51+/-0.73 vs 0.19+/-0.6 mmol l(-1), p < 0.01). These data suggest that adding metformin to insulin in poorly controlled Type 2 DM patients offers an advantage in terms of glycaemic control and lipid plasma profile.
