Depression, High-Mauve Factor, & Recent Research

Depression is characterized by a persistent depressed mood and or interest in things that previously gave pleasure, which is a change for that individual.1 It is estimated that 6.6% of the population in the USA will experience depression.

The mauve factor is hydroxylactam of hemopyrrole, hydroxyhemopyrrolin-3-one (HPL).  Elevated urinary HPL results in neurobehavioral symptoms, which can be improved with nutrients vitamin B6 and zinc.  Increased excretion of HPL is associated with oxidative stress and emotional stress.


High-mauve factor is found in patients with Down syndrome, schizophrenia, autism, ADHD, and alcoholism.2 Pfeiffer et al. reports symptoms of high-mauve include upper abdominal pain, hyperactivity, explosive anger, low stress tolerance, and musculoskeletal pain.  These symptoms are expansive and can be difficult to distinguish from many mental health conditions such as major depression and schizophrenia.

The development of depression is complex and two major models in the literature describe the pathogenesis. The monoamine-deficiency hypothesis states that symptoms related to decreased norepinephrine and serotonin in multiple regions of the brain may be responsible for depression.  Abnormalities in the cortisol response, and chronically elevated cortisol may be contributory. Additionally, abnormal circadian rhythms and impaired synthesis or metabolism of neurotransmitters can result in inflammation causing depression. Twin studies suggest a 37% concordance suggesting genetics contribute to the development of depression.

HPL is correlated inversely with plasma glutathione and red-cell catalase, and directly with plasma nitric oxide. High-mauve denotes individuals that excrete excess HPL, and have resulting erythroid heme depression, low zinc, and increased nitric oxide.  Heme depression and increased nitric oxide results in considerable oxidative stress and inflammation throughout the body and brain.  There are many heme-dependent enzymes, which play vital roles in anti-oxidant defense, including catalase, peroxidase, and CYP450 synthesis. 

Heme synthesis begins with condensation of glycine and succinyl-CoA to form d-aminolevulinic acid (ALA). Vitamin B6, or pyridoxal phosphate (PLP) serves as a coenzyme for d-aminolevulinate synthesis (which is the rate-limiting step in heme synthesis). Aminolevulinic acid (ALA) condensation forms porphobilinogen by zinc-containing ALA dehydratase. The porphyrias are classified as erythropoietic or hepatic, depending on where the enzyme deficiency occurs in the erythropoietic cells of the bone marrow, or the liver. 


Depression and other mental health conditions have been associated with mitochondria dysfunction. Bioenergetics and neurodevelopment are highly influenced by mitochondrial function, and poor function is often due to altered redox balance and chronic low-grade inflammation. N-acetylcysteine has protective effects in multiple models of mitochondrial dysfunctions.3

Research completed by Torres et al. demonstrated protective effects in neurotoxicity associated with pyrroles in urine.  The sulfhydryl groups provided by NAC appear to inhibit the pyrrole-pyrrole crosslinking and prevent 2,5-hexanedion toxicity in a rat model.4


Anti-depressants, escitalopram, and placebo compared to S-adenosyle methionine (SAMe) showed inferior responses in major depression. Results of the study suggest that SAMe provide evidence for the use of SAMe in major depression.5

Same Rx, Higher Prices. Why?

The Institute for Clinical & Economic Review 
The U.S. is the only industrialized nation in the world that has not established an assessment program to determine how drugs are covered and how the drug prices are set. The multi-faceted obstacles in determining the pricing of drugs are embedded within the current healthcare system laws (Medicare, the single largest payer for Rx, is prohibited from negotiating pricing of drugs with the pharmaceutical industry). Visit the ICER website for comparative effectiveness and other analyses.

Withania somnifera & GABA

The botanical known as Ashwagandha (Withania somnifera) is often used for its adaptogenic properties, which modulate general conditions like insomnia, stress, anxiety, and cognitive function. GABA is the inhibitory neurotransmitter in the central nervous system mediating pathological processes such as anxiety, depression, epilepsy, and other cognitive disorders.  The study completed by Candelario et al.(2015) aimed to examine the root extract of Ashwagandha and its constituents, and how they inhibit GABA receptors in the CNS. Results of the study suggest that the key constituents in Ashwagandha may beneficially influence the signaling dysfunction found in general anxiety disorders, sleep disorders, and cognitive disorders by targeting GABA in the CNS.

Novel Mechanistic non-linear model & Circadian Oscillations of hormones in HPA-axis related to Depression

The etiology of depression is discussed in a study by Gudmand-Hoeyer et al. (2014).  While depression is associated with dysregulation of the HPA-axis many of the resulting hormones synthesized in this system are affected and downstream concentrations directly influence the energy in the brain and muscles. These hormones are synthesized at different rates and times during the day.  Utilizing a multi-scale modeling approach, this study was able to show both the circadian and ultradian oscillations of hormones as it is related to depression.  The three parameters varying between groups that were examined in this study reveal hypocortisolemic depressed, hypercortisolemic depressed, and non-depressed. The model utilized in this study allows for the complex interpretation of ACTH levels and the resulting synthesis of cortisol and associated depression.

Depression & HPA-Axis

Regulation of our internal environment involves three systems: the nervous system, immune system, and endocrine system. The hypothalamic-pituitary-adrenal (HPA) axis is integral to all three of these systems and is often disrupted and hyperactive in major depression (MD).  Neuroendocrine stimulation research suggests that negative coping strategies predicts the plasma cortisol response, which is controlled by the HPA-axis. Results of the study by N.Hohne et al.(2014) indicate that subjects with a lifetime history of major depression have HPA-axis dysregulation and negative coping strategies, compared to individuals that have never been depressed.

Laughter Interventions & Quality of Life

The Laughter Club movement (laughter yoga) has inspired researchers to investigate the health effects of simulated laughter. Some health practitioners require researched evidence to suggest laughter as an intervention to patients. Why? I'm not sure. For those of you that need the evidence, here it is…Available evidence on laughter research suggests that laughter has a positive, quantifiable physiological and psychological effect on health leading to an improved quality of life. Specifically, laughter affects the muscular, cardiovascular, respiratory, endocrine, immune, and central nervous systems.
