Special issue on panic disorder: Actual separations and losses during childhood, such parental death, parental separation or divorce (CPL), effect lifelong alterations in the physiological reactivity of the endogenous opioid system of healthy adults.
This is the final, published version of our paper, published in the special issue of Neuroscience & Biobehavioral Reviews Volume 46, Part 3, October 2014, Pages 345–351 Translational approaches to panic disorder http://www.sciencedirect.com/science/article/pii/S0149763414000827 PDF: Preter Klein 2014 final journal version Nov … Continue reading
The relationship between childhood parental loss and metabolic syndrome in obese subjects.
Pro-inflammatory effects of CPL? [M]ultivariate logistic regression analysis revealed that both childhood loss of a parent and a body mass index (BMI) value greater than 50 were significant predictors of metabolic syndrome. This study provides preliminary evidence linking childhood parental loss to risk factors for the development of metabolic syndrome. Continue reading
Association of Childhood Adversities and Early-Onset Mental Disorders With Adult-Onset Chronic Physical Conditions
Important paper on childhood adversities an adult-age chronic medical conditions, published just before our study on endogenous opioid dysregulation after early childhood adversity in psychiatrically and physically “healthy” adults.

N. Szajnberg, MD on “Lifelong opioidergic vulnerability through early life separation”
Bowlby was a careful observer. His entire volume on Loss spoke to the power of early childhood adversity and later life. More recently, a pediatric nephrologist at Kaiser in collaboration with others has shown that early childhood adversities, including loss, results in later adulthood medical ailments (Filetti et al); and Szajnberg and Massie followed Brodie’s cohort at thirty years to demonstrate this clinically.
Yet, Preter and Klein, citing the work of others, have shown pharmacological evidence of what appears to be a lifelong disorder in opiodergic systems due to childhood loss. Continue reading
Maurice Preter MD and Donald F. Klein, MD, DSc: Lifelong opioidergic vulnerability through early life separation: A recent extension of the false suffocation alarm theory of panic disorder.
“[…W]e objectively, experimentally showed a physiological link between endogenous opioid system deficiency and panic-like suffocation sensitivity in healthy adults. This is consonant with the expanded Suffocation-False Alarm Theory of panic suggesting an episodic functional endogenous opioid deficit (Preter and Klein, 1998). The specificity of the naloxone + lactate model of clinical panic should be tested using specific anti-panic components, possibly including opioidergic mixed agonist-antagonists such as buprenorphine. If specific, the naloxone + lactate effect in normal humans affords a screening method for testing putative anti-panic drugs which is currently not available. This could obviate the experimental treatment of panic disorder patients in drug development.
Our data also show for the first time that actual separations and losses during childhood, such parental death, parental separation or divorce (CPL), effect lifelong alterations in the physiological reactivity of the endogenous opioid system of healthy adults.
This result encourages epigenetic inquiry into the effects of CPL on endogenous opioid systems, and their role in resilience under extreme stress. In addition, a redefinition of what constitutes a (truly) healthy control in clinical research protocols may be called for.” Continue reading
