which of the following procedures is a treatment method for acute iron toxicity

Severe poisonings will require IV (intravenous) chelation therapy. The patient receives a series of IVs containing deferoxamine mesylate (Desferal), a chemical that binds to iron in the blood and is then excreted in urine. Deferoxamine can be administered by IV or shot, but the IV route is preferred for easier dose adjustment.

Can iron pills be accidental?

Most iron ingestions are accidental. As for any medication, preventive measures include keeping the bottles of iron supplements, with childproof tops, inaccessible to children. Changing the appearance of prenatal vitamins to make them look less like candy has been considered. This would be ideal.

How long does deferoxamine last?

For severe toxicity, administer deferoxamine for 24 hours. Because these end points are arbitrary, observe the patient for the recurrence of toxicity 2-3 hours after the deferoxamine has been stopped. Adverse effects from deferoxamine are unusual.

Can you monitor asymptomatic patients at home?

Asymptomatic patients may be monitored at home in collaboration with the local poison control center. Observation at home can also be used for patients who have ingested less than 40 mg/kg of elemental iron and who are having mild symptoms (eg, nausea, vomiting). Patients who have ingested children's chewable vitamins plus iron or carbonyl iron or polysaccharide-iron complex formulations should be observed at home with appropriate follow-up. [ 8]

What is the mechanism of iron toxicity?

Mechanism of iron toxicity. Iron is highly reactive, easily alternating between two states – iron III and iron II – in a process which results in the gain and loss of electrons, generating harmful free radicals (atoms or molecules with unpaired electrons).

What are the complications of iron overload?

Complications of iron overload. Untreated transfusional iron overload in thalassaemia major is fatal in the second decade of life, usually as a result of cardiac complications ( Zurlo 1989 ). Iron overload also causes pituitary damage, leading to hypogonadism and poor growth.

What causes iron overload?

Iron overload occurs when iron intake is increased over a sustained period of time, either as a result of red blood cell transfusions or increased absorption of iron through the gastrointestinal tract (GI). Both of these occur in thalassaemia, with blood transfusion therapy being the major cause of iron overload in thalassaemia major ...

Is chelation therapy necessary?

In the absence of any mechanism of the human body to excrete excess iron, chelation therapy is essential and constitutes the second important arm, besides transfusion therapy, of the clinical management of these patients.

Is iron a reactive element?

Iron is highly reactive, easily alternating between two states – iron III and iron II – in a process which results in the gain and loss of electrons, generating harmful free radicals (atoms or molecules with unpaired electrons). These can damage lipid membranes, organelles and DNA causing cell death and the generation of fibrosis. In health, iron is ‘kept safe’ by binding to molecules such as transferrin, but in iron overload their capacity to bind iron is exceeded both within cells and in the plasma compartment. The resulting ‘free iron’ damages many tissues in the body and is fatal unless treated by iron chelation therapy.

Is iron overload fatal?

Untreated transfusional iron overload in thalassaemia major is fatal in the second decade of life, usually as a result of cardiac complications ( Zurlo 1989 ). Iron overload also causes pituitary damage, leading to hypogonadism and poor growth. Endocrine complications, namely diabetes, hypothyroidism and hypoparathyroidism, are also seen. Liver disease with fibrosis and eventually cirrhosis, particularly if concomitant chronic hepatitis is present, is also a serious complication. (These complications are described in greater detail in the relevant chapters of this book.)

What is the goal of chelation therapy?

Goals of iron chelation therapy. The primary goal of chelation therapy is to maintain safe levels of body iron at all times. Unfortunately, once iron overload has accumulated, removal of storage iron is slow and inefficient, because only a small proportion of body iron is available for chelation at any given time.

How to treat iron poisoning in children?

How long does it take for iron poisoning to show up?

Symptoms of iron poisoning usually become evident within 6 hours after an excessive amount of iron is swallowed. Iron corrodes your intestinal lining and is a direct irritant to the stomach. People with iron poisoning can have the following symptoms: Severe vomiting. Diarrhea.

How do you know if you have iron poisoning?

Diarrhea. Abdominal pain. Dehydration and lethargy if not treated adequately. In a child, bloody vomit or stool.

What is IV chelation therapy?

Severe poisonings will require IV (intravenous) chelation therapy. The patient receives a series of IVs containing deferoxamine mesylate ( Desfer al ), a chemical that binds to iron in the blood and is then excreted in urine.

What is the role of iron in the body?

Iron is essential for all living organisms. Many iron-containing proteins and metabolic pathways play a key role in almost all cellular and physiological functions. The diversity of the activity and function of iron and its associated pathologies is based on bond formation with adjacent ligands and the overall structure of the iron complex in proteins or with other biomolecules. The control of the metabolic pathways of iron absorption, utilization, recycling and excretion by iron-containing proteins ensures normal biologic and physiological activity. Abnormalities in iron-containing proteins, iron metabolic pathways and also other associated processes can lead to an array of diseases. These include iron deficiency, which affects more than a quarter of the world’s population; hemoglobinopathies, which are the most common of the genetic disorders and idiopathic hemochromatosis. Iron is the most common catalyst of free radical production and oxidative stress which are implicated in tissue damage in most pathologic conditions, cancer initiation and progression, neurodegeneration and many other diseases. The interaction of iron and iron-containing proteins with dietary and xenobiotic molecules, including drugs, may affect iron metabolic and disease processes. Deferiprone, deferoxamine, deferasirox and other chelating drugs can offer therapeutic solutions for most diseases associated with iron metabolism including iron overload and deficiency, neurodegeneration and cancer, the detoxification of xenobiotic metals and most diseases associated with free radical pathology.

What is oxidative stress toxicity?

Introduction: Oxidative stress toxicity (OST) has been implicated in almost all pathological conditions. Despite the widespread use of natural antioxidants, no pharmaceutical antioxidants have yet been developed or prescribed in medical practise. Antioxidant drugs such as Deferiprone and N-acetylcysteine can target essential pathways of OST in many pathological conditions. The pharmacological parameters required by antioxidant drugs in relation to the OST target characteristics include the determination of the therapeutic index, ADMET and drug interactions. Antioxidant drug development efforts are currently targeting the treatment of severe diseases with no proven effective therapies. Areas covered: This article addresses the damaging effects of oxidative stress toxicity, prospects for the development of pharmaceutical antioxidants and clinical studies using other drugs with antioxidant potential. Expert opinion: Effective antioxidant therapeutic strategies should include the design of protocols for the inhibition of OST through iron chelation, administration of synthetic and natural antioxidants and enhancement of the antioxidant defences by increasing the production of endogenous antioxidants and activation of antioxidant mechanisms. Different therapeutic strategies apply in the use of antioxidant drugs for one or more targets, for prevention, treatment, or of post-treatment effects and for systematic, long-term or short-term applications. The design of new antioxidant drugs and effective protocols which can include Deferiprone and N-acetylcysteine combinations, could lead to the development of a new class of therapeutics for clinical use.

What is ferric maltol?

The trimaltol iron complex (International Non-proprietary Name: ferric maltol) was originally designed, synthesised, and screened in vitro and in vivo in 1980–1981 by Kontoghiorghes G.J. following his discovery of the novel alpha-ketohydroxyheteroaromatic (KHP) class of iron chelators (1978–1981), which were intended for clinical use, including the treatment of iron deficiency anaemia (IDA). Iron deficiency anaemia is a global health problem affecting about one-third of the world’s population. Many (and different) ferrous and ferric iron complex formulations are widely available and sold worldwide over the counter for the treatment of IDA. Almost all such complexes suffer from instability in the acidic environment of the stomach and competition from other dietary molecules or drugs. Natural and synthetic lipophilic KHP chelators, including maltol, have been shown in in vitro and in vivo studies to form stable iron complexes, to transfer iron across cell membranes, and to increase iron absorption in animals. Trimaltol iron, sold as Feraccru or Accrufer, was recently approved for clinical use in IDA patients in many countries, including the USA and in EU countries, and was shown to be effective and safe, with a better therapeutic index in comparison to other iron formulations. Similar properties of increased iron absorption were also shown by lipophilic iron complexes of 8-hydroxyquinoline, tropolone, 2-hydroxy-4-methoxypyridine-1-oxide, and related analogues. The interactions of the KHP iron complexes with natural chelators, drugs, metal ions, proteins, and other molecules appear to affect the pharmacological and metabolic effects of both iron and the KHP chelators. A new era in the treatment of IDA and other possible clinical applications, such as theranostic and anticancer formulations and metal radiotracers in diagnostic medicine, are envisaged from the introduction of maltol, KHP, and similar lipophilic chelators.

Where are automobile workshops located?

Automobile workshops can be found in many places in Pakistan and most of them are located near the residential areas. Some activities in automobile workshops can release heavy metals, having the adverse impacts for human health. Islamabad and Rawalpindi are twin cities in northern Pakistan where automobile workshops have been operated almost forty years and have never been studied their impact on the surroundings. Therefore, there is a need to identify heavy metal contaminants in the groundwater to avoid the health hazards. This research aimed to evaluate the heavy metal contaminants in the groundwater samples from thirty selected locations points near automobile workshops. The physicochemical properties including pH, electrical conductance (EC), total suspended solids (TSS), total dissolved solids (TDS), and the concentrations of anionic (F- and Cl-) and several heavy metal ions were assessed. The pH and TDS values of almost all samples were within the permissible limits. The EC values were ranging from 0.79 to 1.80 µS/cm with an average value of 1.12 µS/cm while the TSS values were ranging from 210 to 620 mg/L with an average value of 431.3 mg/L. Several samples had higher level of F- ions and several others had free of F- ions. The concentrations of Cl- ions were below the permissible limits. Almost all heavy metal ions such as Ni2+, Co2+, Zn2+, Pb2+, Cr3+, Cd2+, Fe2+ and Mn2+ were obtained in higher concentration than the permissible limits, except for As3+ ions. Besides, the existing of one metal has correlation with other metals. In future, the rapid, green, facile, and new method to remove or adsorb the heavy metal ions from groundwater or other environmental water samples can be investigated for large scale production.
