Several factors are thought to influence patients’ ability and willingness to adhere. So far, however, consensus is lacking regarding patient characteristics that predict nonadherence. The purpose of this study was to identify predictors of nonadherence to antidepressant treatment that can be ascertained at treatment start.Method: The present study used data from a randomized controlled trial with the main objective of studying the effect of two different compliance-enhancing programs on treatment adherence and treatment response in 1031 primary care patients with major depression. In this study, logistic regression analyses were performed to examine patient- and illness-related characteristics potentially associated with nonadherence.Results: Nonadherence to antidepressant treatment was predicted by age under 35 or over 64 years, presence of personality disorder, sensation-seeking personality traits, substance abuse, and absence of concomitant medications.Conclusion: Certain patient- and illness-related characteristics may imply an increased risk of nonadherence to antidepressant treatment. Giving special attention to subjects with such characteristics may improve adherence.Keywords: unipolar depression, antidepressant, adherence, compliance, SSRI, predictor

Diabetes in patients with acromegaly treated with pegvisomant: observations from acrostudy

Purpose: To explore the effects of pegvisomant (PEGV) on glucose metabolism in patients with acromegaly within ACROSTUDY, an international, observational, prospective safety surveillance study. Methods: Patients were retrospectively divided into two cohorts, with (DM group) or without diabetes mellitus (no-DM). Parameters of glucose metabolism and IGF-I values were analyzed yearly both cross-sectionally for 4 years (yrs) and longitudinally at 1 and 4–5 yrs of PEGV treatment. Results: Among 1762 patients, 510 (28.9%) had DM before PEGV start. At cross-sectional analyses, in the DM group mean blood glucose was 140.0 ± 58.7 mg/dl at baseline, 116.4 ± 44.8 mg/dl at year 1 and 120.0 ± 44.3 mg/dl at yr 4. Mean HbA1c was 6.6 ± 1.2 % at yr 1 vs. 7.0 ± 1.4 % at baseline. HbA1c was above 6.5% in 61.9% at baseline and ranged from 45.4 to 53.8% at subsequent yearly time points. At the 4-yr longitudinal analysis, in the DM group (n = 109), mean blood glucose decreased by 20.2 mg/dl at yr 4, mean HbA1c was 7.0 ± 1.5% at baseline vs. 6.8 ± 1.4%. Patients achieved IGF-I normalization in 52.1% and 57.4% of cases in the DM and no-DM groups, respectively at 1 year. The mean daily PEGV dose (mg/day) was higher in the DM group (18.2 vs. 15.3) while the absolute change of IGF-I values from baseline was similar in both groups. PEGV was well tolerated in both groups without any unexpected AEs. Conclusions: Patients with DM had a moderate decrease in mean fasting glucose values during PEGV treatment

Adherence to Antidepressant Medication

Non-adherence to medication is a major obstacle in the treatment of depression. The objectives of the present study were to explore the effect of two interventions aiming to increase antidepressant treatment adherence, and to examine long-term consequences and costs of depression in adherent and non-adherent primary care patients. A randomised controlled design was used to assess the respective effects of a written educational adherence enhancing programme and therapeutic drug monitoring in patients with major depression treated with sertraline for 24 weeks. All patients were prospectively followed during two years. Treatment adherence was found in 41% of the 1031 included patients. None of the interventions resulted in a significant increase in adherence rate. However, significantly more patients in the group receiving the written educational material had responded at week 24 as compared to patients in the control group. The overall remission rate after two years was 68%. In total, 34% of the responders experienced at least one relapse. Response and remission rates at week 24, year 1 and year 2 were significantly higher in adherent as compared to non-adherent patients. No relationship between adherence and relapse rate was seen. The mean total cost per patient during two years was KSEK 363 whereof indirect costs represented 87%. No significant differences in costs between intervention groups or between adherent and non-adherent patients could be demonstrated. However, the mean cost per patient was 39% lower for treatment responders as compared to non-responders. Non-adherence was predicted by age below 35 or above 64 years, no concomitant medications, personality disorder, sensation seeking personality traits and substance abuse. The results indicate a strong positive relationship between treatment adherence and clinical outcome. In addition, the study shows that depression is a costly disease and that certain patient characteristics predict non-adherence

Overall and cause-specific mortality in GH-deficient adults on GH replacement.

OBJECTIVE: Hypopituitarism is associated with an increased mortality rate but the reasons underlying this have not been fully elucidated. The purpose of this study was to evaluate mortality and associated factors within a large GH-replaced population of hypopituitary patients. DESIGN: In KIMS (Pfizer International Metabolic Database) 13,983 GH-deficient patients with 69,056 patient-years of follow-up were available. METHODS: This study analysed standardised mortality ratios (SMRs) by Poisson regression. IGF1 SDS was used as an indicator of adequacy of GH replacement. Statistical significance was set to P<0.05. RESULTS: All-cause mortality was 13% higher compared with normal population rates (SMR, 1.13; 95% confidence interval, 1.04-1.24). Significant associations were female gender, younger age at follow-up, underlying diagnosis of Cushing's disease, craniopharyngioma and aggressive tumour and presence of diabetes insipidus. After controlling for confounding factors, there were statistically significant negative associations between IGF1 SDS after 1, 2 and 3 years of GH replacement and SMR. For cause-specific mortality there was a negative association between 1-year IGF1 SDS and SMR for deaths from cardiovascular diseases (P=0.017) and malignancies (P=0.044). CONCLUSIONS: GH-replaced patients with hypopituitarism demonstrated a modest increase in mortality rate; this appears lower than that previously published in GH-deficient patients. Factors associated with increased mortality included female gender, younger attained age, aetiology and lower IGF1 SDS during therapy. These data indicate that GH replacement in hypopituitary adults with GH deficiency may be considered a safe treatment
