- Ochratoxin A (OTA) is a mycotoxin found in food and feed products. Consumers can also take safety measures by choosing products from reputable sources and storing food properly. In one report, the mean value of OTA for the healthy control population was 3.3 1.5ng/mL (ppb) compared to a mean value of 18 7ng/mL (ppb) in those with chronic interstitial nephropathy of unknown origin [57]. National Library of Medicine Ethnic differences are seen in the prevalence of the disease with blacks affected seven times more often as whites with a worse prognosis once the disease is acquired [72]. A Review of the Mechanism of Injury and Treatment Approaches 8600 Rockville Pike They recall evidence of water damage and mold in several of their previous homes and confirmed the presence of elevated levels of indoor mold in their current home. Ochratoxins - You Are The Healer . Symptoms If biopsy samples are available, it would also be useful to test these tissues since elevated levels in the kidney, might support the removal of diseased kidneys at the time of transplantation as opposed to the common practice of leaving them in place. 2023 May;39(2):81-93. doi: 10.1007/s12550-023-00478-2. Her mother reports she required some initial resuscitation, but improved quickly and did not require transfer to neonatal intensive care unit. As a library, NLM provides access to scientific literature. FSGS is a potentially devastating kidney disease that occurs most frequently in children and young adults but can occur at any age. HHS Vulnerability Disclosure, Help INTRODUCTION Ochratoxin A (OTA) is a naturally occurring foodborne mycotoxin found in a wide variety of agricultural commodities worldwide, ranging from cereal grains to dried fruits to wine and coffee. Gautier JC, Richoz J, Welti DH, et al. - Ochratoxin A (OTA) is a mycotoxin produced by fungi that can contaminate food. The nephrotoxicity of OTA is undisputed in the literature in both extensive animal studies and more limited human studies. Additionally, several studies in animals have confirmed a causal connection between OTA exposure and cancers of the urinary tract, liver, and mammary glands [4952]. Lopes P, Sobral MMC, Lopes GR, Martins ZE, Passos CP, Petronilho S, Ferreira IMPLVO. Accessibility Despite the fact that a number of techniques have been suggested to remove OTA from the contaminated products, there are several restrictions to apply successfully these methods in industry.

Ochratoxin A in human blood in relation to nephropathy in Tunisia. Clark's review of ochratoxin in the blood concluded that the highest levels were observed in sampled populations that included persons with kidney disorders with serum level as high as 35100ng/mL (ppb) [1]. The relative contribution of each excretory route is influenced by the degree of serum macromolecular binding as well as differences in the enterohepatic recirculation of OTA [7].

Ochratoxin A in the food chain. Retinol, ascorbic acid and. Ochratoxin A (OTA) is a mycotoxin produced by several fungal species including Aspergillus ochraceus, A. carbonarius, A. niger, and Penicillium verrucosum. Limited information is available on the metabolic disposition of OTA in humans, although it has been suggested that it has a long serum half-life due to strong binding to human serum macromolecules [7, 14]. Immunity and tolerance to Aspergillus involve functionally distinct regulatory T cells and tryptophan catabolism. A kidney already damaged from any cause would be all the more negatively affected by the strain of excreting a potent nephrotoxin. Additionally OTA has been found in breast milk which could represent a significant source of exposure for infants [33, 60]. - The toxin can also lead to cognitive impairment, including memory and learning deficits. Preventing ochratoxin A exposure is crucial in avoiding associated neurological symptoms. Ochratoxin A and Kidney Oxidative Stress: The Role of Nutraceuticals in Veterinary Medicine-A Review. Peak effects were observed in the midbrain, caudate/putamen, and hippocampus [69]. Carcinogenicity of ochratoxin A in experimental animals.

In addition, it can interfere with the metabolism of energy in brain cells, which can lead to cell death. eCollection 2021. Ochratoxin A and Epigenetics Throughout the literature, much of the study of ochratoxin exposure focuses on exposure through ingestion. Clipboard, Search History, and several other advanced features are temporarily unavailable. Two patients histories of FSGS associated with OTA exposure encountered by the authors are presented. Ochratoxin A has a number of toxic effects in animals. Gekle M, Silbernagl S. The role of the proximal tubule in ochratoxin A nephrotoxicity in vivo: toxodynamic and toxokinetic aspects. This could interfere with the DNA repair systems and cell cycle controls systems and serve as an initiating point of carcinogenesis. Mycotoxins' Prevalence in Food Industry By-Products: A Systematic Review. In: Castegnaro M, Plestina R, Dirheimer G, Chernozemsky IN, Bartsch H, editors. Received 2011 Oct 10; Accepted 2011 Nov 7. Because of its long half-life, it accumulates in the food chain [143,144] and is frequently detected in human plasma at nanomolar concentrations Results of a recent biomonitoring study in Chile confirmed the presence of OTA in breast milk at levels such that the tolerable daily intake could be exceeded [75]. Ferrufino-Guardia EV, Tangni EK, Larondelle Y, Ponchaut S. Transfer of ochratoxin A during lactation: exposure of suckling via the milli of rabbit does fed a naturally-contaminated feed. Copyright 2019 Elsevier B.V. All rights reserved. Regular monitoring of food and feed for contamination is important. Unfortunately, in the case of exposures to mycotoxins including ochratoxin, it is imperative to address issues of cross contamination of items exposed to water-damaged/mold contaminated environment. There has been increasing recognition of causes in primary FSGS including genetic, viral, drug toxicity, and others. Other potential sequestrant treatments include the use of charcoal which is included in the military textbook recommendations for exposure to trichothecene mycotoxins which has been associated with Yellow Rain exposure [77].

See this image and copyright information in PMC. She was breastfed for 14 months. Concerns regarding exposure to ochratoxin have primarily centered on exposure to food contaminated with OTA such as wine, beer, coffee, dried vine fruit, grape juices, pork, poultry, dairy, spices, and chocolate [1]. Careers. Within months of starting treatment, the mother reported a significant decrease in the patients urinary protein excretion with the lowest levels found to date on recent testing. The patient worked as a marriage and family therapist from her home office until she was no longer able to work due to her illness. pp. Jonsyn FE, Maxwell SM, Hendrickse RG.

Remember, prevention is the best defense against Ochratoxin A toxicity. Common Neurological Symptoms Caused by Ochratoxin A Exposure, 3. Treatment is then discussed in the context of two patients diagnosed with FSGS who were found to have significantly elevated levels of urine OTA. Signs and symptoms depend on which organs are affected, but in general, invasive aspergillosis can cause: Fever and chills. Al-Anati L, Petzinger E. Immunotoxic activity of ochratoxin A. Montagnoli C, Fallarino F, Gaziano R, et al. Tissue distribution after exposure of animals to OTA has consistently revealed that the greatest concentration is in the kidneys followed by either liver or muscle and then fat [2527], but tissues found to contain OTA also include the adrenal medulla and cortex, skin, myocardium, gastric mucosa, and bone marrow [28]. If elevated levels of urinary OTA are found, there are a number of safe treatments that should be considered to lower the body burden of this mycotoxin. Several hundred different mycotoxins have been identified, but the most commonly observed mycotoxins that present a concern to human health and livestock Keywords: Mycotoxin.
