The increasing consumption of amino acids from a wide variety of sources, including dietary supplements, natural health products, medical foods, infant formulas, athletic and work-out products, herbal medicines, and other national and international categories of nutritional and functional food products, increases the exposure to amino acids to amounts far beyond those normally obtained from the diet, thereby necessitating appropriate and robust safety assessments of these ingredients. Safety assessments of amino acids, similar to all food constituents, largely rely on the establishment of an upper limit [Tolerable Upper Intake Level (UL)] considered to be a guide for avoiding high intake, above which adverse or toxic effects might occur. However, reliable ULs have been difficult or impossible to define for amino acids because of inadequate toxicity studies in animals and scarce or missing clinical data, as well as a paucity or absence of adverse event reporting data.

Eosinophilic fasciitis (EF) is a rare connective tissue disease characterized by symmetrical and painful swelling with a progressive induration and thickening of the skin and soft tissues. The diagnosis of EF is often based on the association of characteristic skin or subcutaneous abnormalities and a thickened fascia with an inflammatory infiltration, mostly composed of lymphocytes and eosinophils. A peripheral eosinophilia is frequently present (60-90%) but is not mandatory for the EF diagnosis. Read More

Drug-induced eosinophilia is a potentially life-threatening adverse effect; clinical manifestations, eosinophilia-myalgia syndrome, mainly include severe skin eruption, fever, hematologic abnormalities, and organ system dysfunction. Using experimental methods to evaluate drug-induced eosinophilia is very complicated, time-consuming, and costly in the early stage of drug development. Thus, in this investigation, we established computational prediction models of drug-induced eosinophilia using SVM and naïve Bayesian approaches. Read More

The daily nutritional requirement for L-tryptophan (Trp) is modest (5 mg/kg). However, many adults choose to consume much more, up to 4-5 g/d (60-70 mg/kg), typically to improve mood or sleep. Ingesting L-Trp raises brain tryptophan levels and stimulates its conversion to serotonin in neurons, which is thought to mediate its actions. Read More

Eosinophilia-myalgia syndrome (EMS) is characterized by subacute onset of myalgias and peripheral eosinophilia, followed by chronic neuropathy and skin induration. An epidemic of EMS in 1989 was linked to consumption of L-tryptophan that had originated from a single source. Following the ban by the Food and Drug Administration (FDA) on the sale of L-tryptophan, the incidence of EMS declined rapidly. Read More

Objective: To assess L-tryptophan (LT) dose, age, sex, and immunogenetic markers as possible risk or protective factors for the development of LT-associated eosinophilia-myalgia syndrome (EMS) and related clinical findings.
Methods: HLA-DRB1 and DQA1 allele typing and Gm/Km phenotyping were performed on a cohort of 94 white subjects with documented LT ingestion and standardized evaluations. Multivariate analyses compared LT dose, age, sex, and alleles among groups of subjects who ingested LT and subsequently developed surveillance criteria for EMS, developed EMS or characteristic features of EMS (EMS spectrum disorder), or developed no features of EMS (unaffected).

Fibrosing disorders comprise a wide spectrum of heterogeneous diseases characterized by sclerosis of the dermis, subcutis, and sometimes the underlying soft tissues and bone. The hallmark of this group of diseases is skin thickening as in systemic sclerosis with a different distribution pattern and for this reason they have also been referred to as "scleroderma-like" disorders. These diseases may have a different clinical course ranging from a benign disease with a localized cutaneous involvement, to a widespread, systemic, life-threatening disease. Read More

Most attempts to reproduce the toxic oil syndrome in animals, either with case-related oils or with refined rapeseed oils, have been unsuccessful. An aniline-denatured rapeseed oil that was subsequently refined according to a protocol yielding relevant markers of "toxic oil" (oil RSO160401) had led to possibly relevant lesions following oral administration in mice. Therefore, in the present study, RSO160401 was subjected to a more extended in vivo testing. Read More

The eosinophilia-myalgia syndrome is accompanied by alterations in L-tryptophan metabolism with elevated levels of L-kynurenine and quinolinic acid having been recorded. It has been suggested that this is due to activation of indoleamine 2,3-dioxygenase by interferon-gamma. It is unknown whether these products of tryptophan metabolism play a role in the pathogenesis of this syndrome and the closely related condition of eosinophilic fasciitis. Read More

In contrast to early epidemiological evidence offering links between eosinophilia-myalgia syndrome (EMS) and microimpurities of L-tryptophan-containing dietary supplements (LTCDS), this account shows why reliance on a finite impurity from one manufacturer is both unnecessary and insufficient to explain the etiology of EMS. Excessive histamine activity has induced blood eosinophilia and myalgia (Greek: mys, muscle + algos, pain). Termination of the multiple actions of histamine is dependent on particular amine oxidases and histamine-N-methyltransferase. Read More

This paper reviews the preclinical and clinical evidence regarding the use of the dietary supplement 5-hydroxytryptophan (5-HTP) for the treatment of depression. In the absence of supplementation with exogenous 5-HTP, the amount of endogenous 5-HTP available for serotonin synthesis depends on the availability of tryptophan and on the activity of various enzymes, especially tryptophan hydroxylase, indoleamine 2,3-dioxygenase, and tryptophan 2,3-dioxygenase (TDO). Factors affecting each of these are reviewed. Read More

5-Hydroxy-L-tryptophan (5-HTP) is the immediate precursor in the biosynthesis of 5-hydroxy-tryptamine (5-HT; serotonin) from the essential amino acid L-tryptophan (L-Trp). The use of L-Trp as a dietary supplement was discontinued in 1989 due to an outbreak of eosinophilia-myalgia syndrome (EMS) that was traced to a contaminated synthetic L-Trp from a single manufacturer. 5-HTP has since become a popular dietary supplement in lieu of the removal of L-Trp from the market.

For most patients who have suspected drug-induced eosinophilic lung disease, the history provides a presumptive diagnosis that can be confirmed by pulmonary findings and eosinophilia after cessation of the drug. As new drugs are developed and released for clinical use, many will result in eosinophilic lung disease in susceptible patients. Therefore, development of pulmonary abnormalities in conjunction with blood or lung eosinophilia after prescription ofa newly released medication should raise the possibility of drug-induced lung disease, even if that medication has not yet been reported to cause eosinophilic lung disease.

Toxic oil syndrome burst upon the scene in Spain in May of 1981, draining the resources of a newly evolving political and social medicine system. The vehicle of the causative toxic agent was identified as an illicit oil that had been diverted from industrial use and refined in order to remove the aniline denaturant, and that was sold in unlabeled 5-liter containers by itinerant salesmen. Over 20,000 people were ultimately affected, and over 1,200 deaths from all causes have been recorded in the affected cohort. Read More
