Evaluation of drug provocation test-related anxiety in patients with drug hypersensitivity.

BACKGROUND: Drug provocation tests (DPTs) are important in the treatment of patients with drug hypersensitivity (DH), but they carry certain hypersensitivity reaction risks, which lead to procedure-related concerns in patients. OBJECTIVE: To investigate DPT-related anxiety and its effect on long-term use of tested drugs. METHODS: The study included patients who underwent DPT from July 1, 2009, to July 1, 2012. After recording the patients' history and characteristics, a variety of psychiatric (Hospital Anxiety and Depression Scale, Panic and Agoraphobia Scale, and the Maudsley Obsessive-Compulsive Inventory) and quality-of-life (36-item Short Form Health Survey) tests were performed. DPT-related anxiety was also evaluated using a visual analog scale. The patients were requestioned about whether they had used the tested drug within 1 year. RESULTS: A total of 126 patients were included in the study. According to the Hospital Anxiety and Depression Scale, 23.4% and 30.6% of the patients had depression and anxiety symptoms, respectively. The mean (SD) visual analog scale anxiety scores after a negative DPT result were lower than those before DPTs (2 [2.5] after vs 5.2 [3.4] before; P < .001). In the long term, 15.9% of the patients did not use the drug because of ongoing anxiety related to drug reactions, despite negative DPT results and symptoms indicated for use of the drug. CONCLUSION: Our findings suggest that DPTs in themselves cause significant anxiety in patients with DH. Importantly, anxiety levels decreased after a negative test result. However, our results also suggested that a negative DPT result is not convincing enough for some patients to use the tested drug when needed in the future. Therefore, supporting strategies appear to be the most effective way to eliminate DH-related anxiety of patients.

Social support and the incidence and persistence of depression between antenatal and postnatal examinations in Turkey: a cohort study.

OBJECTIVES: This study aims to measure incidence and persistence of depression and to investigate the influence of self-reported antenatal social support and traditional/nuclear family structure on incidence and persistence of depression between the third trimester of pregnancy and following childbirth. We hypothesised that lower antenatal social support would be associated with incidence and persistence of case-level depressive symptoms and the family structure would have an effect on the incidence and persistence of depressive symptoms. SETTINGS: The cohort study described here was carried out in and around Ankara the capital of Turkey, because of the considerable heterogeneity of the population in terms of traditional Middle Eastern and 'modern' Western lifestyle and social environment. Samples were drawn from 20 urban and rural antenatal clinics (mainly primary care settings) within the geographic catchment. PARTICIPANTS: Of 730 women recruited in their third trimester, 578 (79.2%) were re-examined between 2 and 6 months after childbirth. Exclusion criteria were as follows: aged younger than 18 years, illiteracy, significant health problems and refusal to participate. PRIMARY AND SECONDARY OUTCOME MEASURES: Close Persons Questionnaire items enquired about relationships with the husband, mother and mother-in-law and depression was ascertained using the Edinburgh Postnatal Depression Scale at the each assessments. RESULTS: In those followed, onset of postnatal depression occurred in 13.9% and persistence of antenatal depression in 49.7%. After adjustment, worse emotional support from the mother-in-law was significantly associated with postnatal depression incidence (OR=0.93, 95% CI 0.87 to 0.99) and worse emotional support from the husband with postnatal persistence (OR=0.89, 95% CI 0.83 to 0.96) of antenatal depression. Family structure was not a risk or modifying factor. CONCLUSIONS: The incidence and persistence of postnatal depression in this Middle Eastern cohort were comparable to international findings. Certain family relationships predicted incidence and persistence of postnatal depression but no role of traditional/nuclear family structure was found.
