Neuroendocrine mechanisms of immune dysregulation: applications to allergy and asthma

OBJECTIVE

To review the current information and hypotheses related to the underlying mechanisms that link psychological stress and asthma activity via a neuroimmune network dysfunction that may manifest as increased morbidity of immune diseases, such as asthma.

DATA SOURCES

Literature searches of MEDLINE for published human and animal studies and review articles published in English-language periodicals. Keywords searched included individual and various combinations of psychoneuroimmunology, neuroimmune, neuroimmunology, stress, immunity, allergy, asthma, and inflammation. Both review articles and specific hypothesis-driven articles that focused on immune effects of stress were included. Manuscripts that focused on animal studies were excluded from this review.

STUDY SELECTION

Representative studies that reflect the consensus of the field based on the expert opinion of the author.

RESULTS

This article demonstrates the established relationships between the neuroendocrine and immune systems and the impact of both acute and chronic psychological stress on neuroendocrine and immune network function. The adverse impact of stress appears to occur more on immune dysregulation rather than immune suppression.

CONCLUSION

Psychological stress, allergy and asthma morbidity, and allergy and asthma incidence are all steadily increasing in our society. Establishing a firm relationship can provide a possible new therapeutic direction for evaluation and management of difficult-to-treat patients and possible prophylactic strategies in susceptible populations.

The rationale and foundations of group psychotherapy for women with metastatic breast cancer

Group psychotherapy has become an important modality of intervention in contemporary psychooncology. This article reviews and describes the rationale and foundations for group psychotherapy for women with metastatic breast cancer. It emerges from a replication study of an earlier study performed by Spiegel (Spiegel, Bloom, Kraemer & Gottheil, 1989), which demonstrated that participation in structured group psychotherapy resulted in improved psychosocial adjustment and a significant survival effect on women with metastatic breast cancer. Other intervention studies, psychosocial effects of psychosocial interventions, as well as psychosocial variables associated with the course of illness, are described. The contribution of existential considerations in psychotherapy is also articulated as a component of the group-supportive expressive intervention. Clinical illustrations, emerging from ongoing treatment groups, are used to demonstrate theoretical concepts.

Factors related to non-attendance in a population based melanoma screening program

A total of 127 non-attenders in a population-based melanoma screening program, 58 women and 69 men, were asked in a telephone interview about reasons for non-attendance. Of those, 105 also completed a mailed questionnaire, measuring perceived susceptibility to and knowledge about melanoma. During the same period, attenders (n = 286) at the screening clinic completed the same questionnaire. The most commonly reported reasons for non-attendance were 'I forgot about it', 'lack of time' and 'no need for examination'. A majority of non-attenders held a positive attitude towards preventive programs in general and to the present invitation. Most of the improvements suggested by the non-attenders were strategies to reduce practical barriers. Non-attenders scored lower than attenders on perceived susceptibility. High and equal levels of knowledge about melanoma were found among attenders and non-attenders. Men were more likely to be non-attenders. Higher perceived susceptibility and a higher level of knowledge about melanoma were found among women as compared to men. The results suggests that there is potential to increase attendance in future melanoma programs by reducing practical barriers.
