GLORIOSA SUPERBA
Family; Colchicaceae
Flame lily; glory lily
All parts of the plant, especially the
tubers, are extremely poisonous.
Colchicine, an alkaloid, is responsible
for the toxic effect.
The species also contains another
alkaloid 'gloriosine'.
Gkf 1
Colchicine
The toxic properties of the plant are
essentially due to the highly active
alkaloid - colchicine.
Colchicine: CAS number: 64-86-8
Molecular formula: C22H25NO6
Molecular weight: 399.44 Structural
name: colchicine
Other chemical contents
3-desmethyl colchicine,
beta-lumicolchicine,
N-Formyldesacetyl-colchicine,
2-desmethyl colchicine,
Chelidonic acid and
Salicylic acid
USES/CIRCUMSTANCES OF POISONING
The tuber is used traditionally for the Rx of
Bruises and sprains,
colic, chronic ulcers,
haemorrhoids,
cancer, impotence,
nocturnal seminal emissions,
leprosy and also
for inducing labour pains and
Other uses
Because of its similar pharmacological
action, the plant is sometimes used as
an adulterant of aconite ( Aconitum
sp.)
The leaf juice to kill head lice
Ingredient in arrow poisons.
Flowers&tubers
Flowers are used in religious ceremonies.
The tuber has commonly been used as a
suicidal agent among women in rural areas
and it has also been used for homicide.
The tuber also claims antidotal properties to
snake- bite and in India it is commonly
placed on window sills to deter snakes.
Many cultures believe the species to
have various magical properties.
High risk circumstances
In parts of tropical Africa and Asia
the tubers of G. Superba may be
mistakenly eaten in place of Sweet
Potatoes (Ipomoea batatas) since the
former is a weed of farmland and the
tubers resemble those of
Sweet Potatoes.
High risk geographical areas
The highest risk areas are likely to be
throughout the natural range of the
species (i.e. tropical Africa and Asia,
including Sri Lanka).
Accidental exposure to the plant may
also occur in cool temperate countries
of the West where it is grown as
an ornamental.
ROUTES OF EXPOSURE
1 Oral Ingestion of tubers or other parts
either Intentionally or accidentally.
2 Inhalation,
3 Dermal
4 Eye
5 Parenteral all NDA
KINETICS
Absorption by route of exposure
Colchicine is readily absorbed from the
Gastrointestinal tract.
Absorption may be modified by pH,
contents in the stomach and
intestinal motility.
Distribution by route of exposure
Colchicine is actively taken up
intracellularly.
Approximately 50% circulating
colchicine is bound to plasma
proteins.
The apparent volume of
distribution exceeds total body
water (2.2 賊 0.8 1/kg)
Biological half-life
by route of exposure Colchicine has an
extremely short plasma half life of
about 20 minutes (Ellenhorn et al., 1996).
Metabolism Colchicine is partially
deacetylated in the liver although as
much as 20% may be excreted
unchanged by the kidneys.
Large amounts of both colchicine and its
metabolites are subjected to
Elimination and excretion
Colchicine and its
metabolites are
excreted in urine and
faeces
Mode of action
Colchicine affects cell membrane
structure indirectly by inhibiting the
synthesis of membrane constituents
It binds to tubulin (the structural proteins
of microtubules) preventing its
polymerization into microtubules.
This antimiotic property disrupts the spindle
apparatus that separates chromosomes
high metabolic rate-cells
Cells with high metabolic rates (e.g. intestinal
epithelium, hair follicles and bone marrow)
are the most involved by the arrest of mitosis.
The variable effects of colchicine may depend on its
binding to the protein subunit of microtubules with
subsequent disruption of microtubule functions
Colchicine also has an inhibitory effect on various
phosphatases Gloriosine also has an
antimitotic effect (Gooneratne, 1966).
Toxicity
Human data
Adults, Nickolls (1965) has suggested that
the lethal dose of colchicine for man may
be about 60 mg although smaller
amounts have also caused death
(Angunawela &Fernando,1971).
Gooneratne (1966) has reported a patient
who survived after ingestion of 350 mg
of colchicine tuber.
LD50
Children No data
available. Relevant animal
data LD50 of colchicine
for rats was 5 mg/kg
(Dunuwille et al., 1968).
Urine analysis
G. superba tubers are used
for abortion (Duke, 1985).
Urine analysis could show
haematuria, proteinuria or
haemoglobin casts.
The commonest clinical
presentation
Severe gastroenteritis
NVD with blood leading to dehydration,
hypovolaemic, shock
&ARF.
Muscle weakness, hypoventilation,
ascending polyneuropathy, bone marrow
depression and coagulation Disorders.
are the other features of poisoning.
Death
Death in severe poisoning occurs due
to shock or respiratory failure although
haemorrhagic or infective
complications may cause
death after the first
day.
Cardiovascular
Heart - there is no direct effect on the
heart,but fluid and electrolyte loss,
often causes hypovolaemic
shock manifested by
hypotension and tachycardia.
Respiratory
Respiratory failure is thought to be due
to the paralysis of intercostal muscles
rather than the direct depression of the
respiratory centre by colchicine
(Angunawela & Fernando, 1971).
The patient may be dyspnoeic
and cyanotic.
Neurological
Central nervous system (CNS)
There is progressive paralysis of the
central nervous system and peripheral
nervous system (Wijesundere, 1986).
Confusion and delirium may develop
either secondary to poor cerebral
perfusion or as a result of direct
cerebral toxicity (Ellenhorn et al., 1996).
NS
It may also cause convulsions,
restlessness and coma.
Peripheral nervous system
Ascending polyneuropathy, weakness,
loss of deep tendon reflexes may be
described.
Autonomic nervous system NDA
Skeletal and smooth muscle
Colchicine could have a direct toxic
effect on skeletal muscles causing
muscular weakness.
Rhabdomyolysis may occur with
significant increase in muscle enzymes
and myoglobinuria as a result of direct
muscular damage.
Muscle weakness that may persist for many
weeks may contribute to respiratory
deficiency (Ellenhorn et al., 1996).
Gastrointestinal
Gastroenteritis including nausea,
vomiting and diarrhoea with blood
accompanied by colic and tenesmus.
Loss of fluids and electrolytes
leads to hypovolaemia.
Intestinal ileus may develop within the first
several days and may persist up to a week
(Ellenhorn et al., 1996).
Hepatic
Colchicine may
exert direct hepatic
toxicity with
moderate cytolysis.
Renal
Any direct toxic effect of the toxin on
kidney is not clear.
Renal failure is probably secondary to
excess fluid loss or hypovolaemia and
is preceded by oliguria and haematuria.
Proteinuria could also occur (Murray et
al., 1983).
Endocrine and reproductive
systems
Vaginal bleeding has been reported as a feature of
intoxication. Tubers are used as an abortifacient
in some countries.
Dermatological Alopecia usually occurs one or two
weeks after the ingestion of G. superba.
A case of generalized depilation has also been
reported (Gooneratne, 1966). Desquamative
dermatitis has been reported as another
dermatologic manifestation (Angunawela &
Fernando, 1971).
Both these conditions can be attributed to the
antimitotic activity of the colchicine and gloriosine.
Eye, ear, nose, throat
local effects Subconjunctival
haemorrhages have been observed
(Gooneratne, 1966). Burning and
rawness of the throat may be early
symptoms of toxicity.
Haematological
BM depressant- transient leucocytosis
followed by leucopenia. thrombocytopenia
that may give rise to various coagulation
disorders resulting in vaginal bleeding,
conjunctival and gastrointestinal
haemorrhages. Severe thrombocytopenia
occurring within 6 hours of poisoning has
been documented (Saravanapavananthan,
1985). Anaemia may occur, mostly secondary
to haemorrhages
ImmunologicalPatients are prone to
infections as a result of leucopenia.
Metabolic Acid-base disturbances Metabolic
acidosis.Fluid and electrolyte disturbances
There is an extensive fluid and electrolyte
loss due to intense vomiting and diarrhoea or
sometimes due to haemorrhages.
Hypokalaemia, hypocalcaemia,
hypophosphataemia and hyponatraemia may
occur (Murray et al., 1983).
Pregnancy: Data on effects of G.
superba on the foetus are not available.
However, colchicine is contraindicated
in pregnancy. Down's syndrome and
spontaneous abortions have been
reported.
MANAGEMENT 10.1 General principles Hospitalize
the patient immediately. Constant and prolonged
monitoring is essential. Ensure adequate ventilation.
Before instituting symptomatic and supportive
therapy remove the plant material from
gastrointestinal tract by emesis or gastric lavage
without delay to minimize further absorption. Give
adequate intravenous fluids. Correct any electrolyte
imbalance. Maintain a fluid balance chart. Specific
measures should also be taken for the management
of shock. Cardiac monitoring is useful. Early forced
diuresis may be of value. Specific fragments a) b)
have been experimented on animals. No human data
are available.
Life supportive procedures and
symptomatic/specific treatment
Observation and monitoring: Monitor
pulse, respiration and blood pressure.
Fluid and electrolytes replacement:
Give adequate oral fluids. If the patient
is unable to take oral fluids Ha 9 + 14.
Hypotension and shock:
Hypotension and shock: Fluid loss may
lead to hypovolaemic shock with
hypotension: Correct hypotension as
required. Ensure a clear airway,
improve ventilation and give oxygen
(Ha 4 + 5 + 6).
Decontamination If consciousness is not
impaired AP4 + AP
Enhanced elimination Forced diuresis,
if instituted early should be of benefit
by eliminating colchicine.
Haemodialysis, haemoperfusion and other
relevant measures are of no value because of
large volume of distribution and limited renal
excretion of colchicine (Ellenhorn et al.,
1996).
Antidote/antitoxin treatment
Adults There is no specific antidote available,
but immunotherapy (fragments fab) is
available for clinical trial on humans in some
countries (France).
Children There is no specific antidote
available, but immunotherapy (fragments fab)
is available for clinical trial on humans in
some countries (France).
CLINICAL EFFECTS
Acute poisoning
Ingestion Acute manifestations begin two to
six hours after ingestion and consist of
burning pain in the mouth and throat
with thirst, followed by nausea, intense
vomiting, colicky abdominal pain and
severe diarrhoea with blood, leading to
hypotension and shock.
course
Delirium, loss of consciousness, convulsions,
respiratory distress,
haematuria, oliguria,
transient leucocytosis followed by leucopenia,
thrombocytopenia with haemorrhages,
anaemia,
muscle weakness which may progress to
polyneuropathy are seen in the second or third day.
Alopecia occurs 1 to 2 weeks after intoxication as a
late manifestation in survivors.
Early haemodynamic monitoring is very
helpful (Murray et al., 1983).
Respiratory: If respiratory depression is present assisted ventilation
and oxygen may be necessary.
Renal failure: Renal failure with oliguria is a common feature. Maintain
an adequate urine output with plenty of intravenous fluids.
Established renal failure may require peritoneal or haemodialysis.
Leucopenia: Fresh blood transfusions are necessary to correct
leucopenia.
Prophylactic antibiotic therapy is advisable if leucopenia is present.
Coagulation disorders: If clotting time is abnormal, vitamin K and
fresh frozen plasma should be given.
Haemorrhagic manifestations should be treated with fresh blood
transfusions.
Hypothermia: This may be a poor prognostic sign. Adopt measures to
keep the patient warm.

  • 31. Elimination and excretion Colchicine and its metabolites are excreted in urine and faeces
  • 32. Mode of action Colchicine affects cell membrane structure indirectly by inhibiting the synthesis of membrane constituents It binds to tubulin (the structural proteins of microtubules) preventing its polymerization into microtubules. This antimiotic property disrupts the spindle apparatus that separates chromosomes
  • 33. high metabolic rate-cells Cells with high metabolic rates (e.g. intestinal epithelium, hair follicles and bone marrow) are the most involved by the arrest of mitosis. The variable effects of colchicine may depend on its binding to the protein subunit of microtubules with subsequent disruption of microtubule functions Colchicine also has an inhibitory effect on various phosphatases Gloriosine also has an antimitotic effect (Gooneratne, 1966).
  • 34. Toxicity Human data Adults, Nickolls (1965) has suggested that the lethal dose of colchicine for man may be about 60 mg although smaller amounts have also caused death (Angunawela &Fernando,1971). Gooneratne (1966) has reported a patient who survived after ingestion of 350 mg of colchicine tuber.
  • 35. LD50 Children No data available. Relevant animal data LD50 of colchicine for rats was 5 mg/kg (Dunuwille et al., 1968).
  • 36. Urine analysis G. superba tubers are used for abortion (Duke, 1985). Urine analysis could show haematuria, proteinuria or haemoglobin casts.
  • 37. The commonest clinical presentation Severe gastroenteritis NVD with blood leading to dehydration, hypovolaemic, shock &ARF. Muscle weakness, hypoventilation, ascending polyneuropathy, bone marrow depression and coagulation Disorders. are the other features of poisoning.
  • 38. Death Death in severe poisoning occurs due to shock or respiratory failure although haemorrhagic or infective complications may cause death after the first day.
  • 39. Cardiovascular Heart - there is no direct effect on the heart,but fluid and electrolyte loss, often causes hypovolaemic shock manifested by hypotension and tachycardia.
  • 40. Respiratory Respiratory failure is thought to be due to the paralysis of intercostal muscles rather than the direct depression of the respiratory centre by colchicine (Angunawela & Fernando, 1971). The patient may be dyspnoeic and cyanotic.
  • 41. Neurological Central nervous system (CNS) There is progressive paralysis of the central nervous system and peripheral nervous system (Wijesundere, 1986). Confusion and delirium may develop either secondary to poor cerebral perfusion or as a result of direct cerebral toxicity (Ellenhorn et al., 1996).
  • 42. NS It may also cause convulsions, restlessness and coma. Peripheral nervous system Ascending polyneuropathy, weakness, loss of deep tendon reflexes may be described. Autonomic nervous system NDA
  • 43. Skeletal and smooth muscle Colchicine could have a direct toxic effect on skeletal muscles causing muscular weakness. Rhabdomyolysis may occur with significant increase in muscle enzymes and myoglobinuria as a result of direct muscular damage. Muscle weakness that may persist for many weeks may contribute to respiratory deficiency (Ellenhorn et al., 1996).
  • 44. Gastrointestinal Gastroenteritis including nausea, vomiting and diarrhoea with blood accompanied by colic and tenesmus. Loss of fluids and electrolytes leads to hypovolaemia. Intestinal ileus may develop within the first several days and may persist up to a week (Ellenhorn et al., 1996).
  • 45. Hepatic Colchicine may exert direct hepatic toxicity with moderate cytolysis.
  • 46. Renal Any direct toxic effect of the toxin on kidney is not clear. Renal failure is probably secondary to excess fluid loss or hypovolaemia and is preceded by oliguria and haematuria. Proteinuria could also occur (Murray et al., 1983).
  • 47. Endocrine and reproductive systems Vaginal bleeding has been reported as a feature of intoxication. Tubers are used as an abortifacient in some countries. Dermatological Alopecia usually occurs one or two weeks after the ingestion of G. superba. A case of generalized depilation has also been reported (Gooneratne, 1966). Desquamative dermatitis has been reported as another dermatologic manifestation (Angunawela & Fernando, 1971). Both these conditions can be attributed to the antimitotic activity of the colchicine and gloriosine.
  • 48. Eye, ear, nose, throat local effects Subconjunctival haemorrhages have been observed (Gooneratne, 1966). Burning and rawness of the throat may be early symptoms of toxicity.
  • 49. Haematological BM depressant- transient leucocytosis followed by leucopenia. thrombocytopenia that may give rise to various coagulation disorders resulting in vaginal bleeding, conjunctival and gastrointestinal haemorrhages. Severe thrombocytopenia occurring within 6 hours of poisoning has been documented (Saravanapavananthan, 1985). Anaemia may occur, mostly secondary to haemorrhages
  • 50. ImmunologicalPatients are prone to infections as a result of leucopenia. Metabolic Acid-base disturbances Metabolic acidosis.Fluid and electrolyte disturbances There is an extensive fluid and electrolyte loss due to intense vomiting and diarrhoea or sometimes due to haemorrhages. Hypokalaemia, hypocalcaemia, hypophosphataemia and hyponatraemia may occur (Murray et al., 1983).
  • 51. Pregnancy: Data on effects of G. superba on the foetus are not available. However, colchicine is contraindicated in pregnancy. Down's syndrome and spontaneous abortions have been reported.
  • 52. MANAGEMENT 10.1 General principles Hospitalize the patient immediately. Constant and prolonged monitoring is essential. Ensure adequate ventilation. Before instituting symptomatic and supportive therapy remove the plant material from gastrointestinal tract by emesis or gastric lavage without delay to minimize further absorption. Give adequate intravenous fluids. Correct any electrolyte imbalance. Maintain a fluid balance chart. Specific measures should also be taken for the management of shock. Cardiac monitoring is useful. Early forced diuresis may be of value. Specific fragments a) b) have been experimented on animals. No human data are available.
  • 53. Life supportive procedures and symptomatic/specific treatment Observation and monitoring: Monitor pulse, respiration and blood pressure. Fluid and electrolytes replacement: Give adequate oral fluids. If the patient is unable to take oral fluids Ha 9 + 14. Hypotension and shock:
  • 54. Hypotension and shock: Fluid loss may lead to hypovolaemic shock with hypotension: Correct hypotension as required. Ensure a clear airway, improve ventilation and give oxygen (Ha 4 + 5 + 6).
  • 55. Decontamination If consciousness is not impaired AP4 + AP Enhanced elimination Forced diuresis, if instituted early should be of benefit by eliminating colchicine. Haemodialysis, haemoperfusion and other relevant measures are of no value because of large volume of distribution and limited renal excretion of colchicine (Ellenhorn et al., 1996).
  • 56. Antidote/antitoxin treatment Adults There is no specific antidote available, but immunotherapy (fragments fab) is available for clinical trial on humans in some countries (France). Children There is no specific antidote available, but immunotherapy (fragments fab) is available for clinical trial on humans in some countries (France).
  • 57. CLINICAL EFFECTS Acute poisoning Ingestion Acute manifestations begin two to six hours after ingestion and consist of burning pain in the mouth and throat with thirst, followed by nausea, intense vomiting, colicky abdominal pain and severe diarrhoea with blood, leading to hypotension and shock.
  • 58. course Delirium, loss of consciousness, convulsions, respiratory distress, haematuria, oliguria, transient leucocytosis followed by leucopenia, thrombocytopenia with haemorrhages, anaemia, muscle weakness which may progress to polyneuropathy are seen in the second or third day. Alopecia occurs 1 to 2 weeks after intoxication as a late manifestation in survivors.
  • 59. Early haemodynamic monitoring is very helpful (Murray et al., 1983). Respiratory: If respiratory depression is present assisted ventilation and oxygen may be necessary. Renal failure: Renal failure with oliguria is a common feature. Maintain an adequate urine output with plenty of intravenous fluids. Established renal failure may require peritoneal or haemodialysis. Leucopenia: Fresh blood transfusions are necessary to correct leucopenia. Prophylactic antibiotic therapy is advisable if leucopenia is present. Coagulation disorders: If clotting time is abnormal, vitamin K and fresh frozen plasma should be given. Haemorrhagic manifestations should be treated with fresh blood transfusions. Hypothermia: This may be a poor prognostic sign. Adopt measures to keep the patient warm.
