Delirium tremens

Delirium tremens (DTs), (Latin, "shaking frenzy"), is a rapid onset of confusion usually caused by withdrawal from alcohol.[2] When it occurs, it is often three days into the withdrawal symptoms and lasts for two to three days.[2] Physical effects may include shaking, shivering, irregular heart rate, and sweating.[1] People may also hallucinate.[2] Occasionally, a very high body temperature or seizures (colloquially known as "rum fits")[5][6] may result in death.[2] Alcohol is one of the most dangerous drugs to withdraw from.[7]

Delirium tremens typically occurs only in people with a high intake of alcohol for more than a month.[8] A similar syndrome may occur with benzodiazepine and barbiturate withdrawal.[3] Withdrawal from stimulants, such as cocaine, does not have major medical complications.[9] In a person with delirium tremens it is important to rule out other associated problems such as electrolyte abnormalities, pancreatitis, and alcoholic hepatitis.[2]

Prevention is by treating withdrawal symptoms using similarly acting compounds to taper off the use of the precipitating substance in a controlled fashion.[2] If delirium tremens occurs, aggressive treatment improves outcomes.[2] Treatment in a quiet intensive care unit with sufficient light is often recommended.[2] Benzodiazepines are the medication of choice with diazepam, lorazepam, chlordiazepoxide, and oxazepam all commonly used.[8] They should be given until a person is lightly sleeping.[2] Non-benzodiazepines are often used as adjuncts to manage the sleep disturbance associated with condition. The antipsychotic haloperidol may also be used,[2] as a major tranquilizer, in order to combat the overactivity and possible excitotoxicity caused by the withdrawal from a GABA-ergic sedative. The vitamin thiamine is recommended to be given intramuscularly,[2] because long term high alcohol intake and the often attendant nutritional deficit damages the small intestine, and so leads to a thiamine deficiency which sometimes cannot be rectified by supplement pills alone.

Mortality without treatment is between 15% and 40%.[4] Currently death occurs in about 1% to 4% of cases.[2]

About half of people with alcoholism will develop withdrawal symptoms upon reducing their use.[2] Of these, 3% to 5% develop DTs or have seizures.[2]

The name delirium tremens was first used in 1813; however, the symptoms were well described since the 1700s.[8] The word "delirium" is Latin for "going off the furrow," a plowing metaphor.[4] It is also called the shaking frenzy and Saunders-Sutton syndrome.[4] There are numerous nicknames for the condition, including "the DTs" and "seeing pink elephants".

Signs and symptoms

The main symptoms of delirium tremens are nightmares, agitation, global confusion, disorientation, visual and auditory hallucinations,[10] tactile hallucinations, fever, high blood pressure, heavy sweating, and other signs of autonomic hyperactivity (fast heart rate and high blood pressure). These symptoms may appear suddenly but typically develop two to three days after the stopping of heavy drinking, being worst on the fourth or fifth day.[11]

These symptoms are characteristically worse at night.[12] For example, in Finnish, this nightlike condition is called "liskojen yö", "the night of the lizards", for its sweatiness, general unease, and hallucinations tending towards the unseemly and frightening.

In general, DT is considered the most severe manifestation of alcohol, or other GABA-receptor active drug, withdrawal, and occurs 2–10 days following the last drink.[10] It often overcomes the patient by surprise, because a brief period of uneventful sobriety of 1–2 days tends to precede it, it can fully manifest itself within a single hour, and unlike usual withdrawal symptoms experienced by an alcoholic, the condition will not easily go away using the typical intake amount or schedule of the drug.

Other common symptoms include intense perceptual disturbance such as visions or feelings of insects, snakes, or rats. These may be hallucinations or illusions related to the environment, e.g., patterns on the wallpaper or in the peripheral vision that the patient falsely perceives as a resemblance to the morphology of an insect, and are also associated with tactile hallucinations such as sensations of something crawling on the subject—a phenomenon known as formication. Delirium tremens usually includes extremely intense feelings of "impending doom". Severe anxiety and feelings of imminent death are common DT symptoms.[13]

DT can sometimes be associated with severe, uncontrollable tremors of the extremities and secondary symptoms, such as anxiety, panic attacks, and paranoia. Confusion is often noticeable to onlookers as those with DT will have trouble forming simple sentences or making basic logical calculations.

DT should be distinguished from alcoholic hallucinosis, the latter of which occurs in approximately 20% of hospitalized alcoholics and does not carry a risk of significant mortality. In contrast, DT occurs in 5–10% of alcoholics and carries up to 15% mortality with treatment and up to 35% mortality without treatment.[14]

Causes

Delirium tremens is mainly caused by a long period of drinking being stopped abruptly. Withdrawal leads to a biochemical regulation cascade.

Delirium tremens is most common in people who are in alcohol withdrawal, especially in those who drink 10–11 standard drinks (equivalent of 7 to 8 US pints (3 to 4 L) of beer, 4 to 5 US pints (1.9 to 2.4 L) of wine or 1 US pint (0.5 L) of distilled beverage) daily. Delirium tremens commonly affects those with a history of habitual alcohol use or alcoholism that has existed for more than 10 years.[15]

Pathophysiology

Delirium tremens is a component of alcohol withdrawal hypothesized to be the result of compensatory changes in response to chronic heavy alcohol use. Alcohol positively allosterically modulates the binding of GABA, enhancing its effect and resulting in inhibition of neurons projecting into the nucleus accumbens, as well as inhibiting NMDA receptors. This combined with desensitization of alpha-2 adrenergic receptors, results in a homeostatic upregulation of these systems in chronic alcohol use.[16]

When alcohol use ceases, the unregulated mechanisms result in hyperexcitability of neurons as natural GABAergic systems are down-regulated and excitatory glutamatergic systems are upregulated. This combined with increased noradrenergic activity results in the symptoms of delirium tremens.[16]

Diagnosis

Diagnosis is mainly based on symptoms. In a person with delirium tremens, it is important to rule out other associated problems, such as electrolyte abnormalities, pancreatitis, and alcoholic hepatitis.[2]

Treatment

Delirium tremens due to alcohol withdrawal can be treated with benzodiazepines. High doses may be necessary to prevent death.[17] Amounts given are based on the symptoms. Typically the person is kept sedated with benzodiazepines, such as diazepam, lorazepam, chlordiazepoxide, or oxazepam.

In some cases antipsychotics, such as haloperidol may also be used. Older drugs such as paraldehyde and clomethiazole were formerly the traditional treatment but have now largely been superseded by the benzodiazepines.[18]

Acamprosate is occasionally used in addition to other treatments, and is then carried on into long-term use to reduce the risk of relapse. If status epilepticus occurs it is treated in the usual way.

It can also be helpful to provide a well lit room as people often have hallucinations.[19]

Alcoholic beverages can also be prescribed as a treatment for delirium tremens,[20] but this practice is not universally supported.[21]

High doses of thiamine often by the intravenous route is also recommended.[2]

Society and culture

Nicknames for delirium tremens include "the DTs", "the shakes", "the oopizootics", "barrel-fever", "the blue horrors", "the rat's", "bottleache", "bats", "the drunken horrors", "seeing pink elephants", "gallon distemper", "quart mania", "heebie jeebies", "pink spiders", and "riding the ghost train",[22] as well as "ork orks", "the zoots", "the 750 itch", and "pint paralysis". Another nickname is "the Brooklyn Boys", found in Eugene O'Neill's one-act play Hughie set in Times Square in the 1920s.[23] Delirium tremens was also given an alternate medical definition since at least the 1840s, being known as mania a potu, which translates to 'mania from drink'.[24]

English author George Eliot provides a case involving delirium tremens in her novel Middlemarch (1871–72). Alcoholic scoundrel John Raffles, both an abusive stepfather of Joshua Riggs and blackmailing nemesis of financier Nicholas Bulstrode, dies, whose "death was due to delirium tremens" while at Peter Featherstone's Stone Court property. Housekeeper Mrs. Abel provides Raffles' final night of care per Bulstrode's instruction whose directions given to Abel stand adverse to Tertius Lydgate's orders.

"'Remember, if he calls for liquors of any sort, not to give it to him.'" (Lydgate to Bulstrode). "...he gave directions to Bulstrode as to the doses, and the point at which they should cease. He insisted on the risk of not ceasing, and repeated his order that no alcohol should be given.' (Bulstrode reflecting): "The thought was, that he had not told Mrs. Abel when the dose of opium must cease. ... He walked up-stairs, candle in hand, not knowing whether he should straitaway enter his room and go to bed, or turn to the patient's room and rectify his omission. ... He turned to his room. Before he had quite undressed, Mrs. Abel rapped at his door ...'If you please sir, should I have no brandy nor nothing to give the poor creetur? ...When I nursed my poor master, Mr. Robisson, I had to give him port-wine and brandy constant, and a big glass at a time,' added Mrs. Abel with a touch of remonstrance in her tone. ...a key was thrust through the inch of doorway, and Mr. Bulstrode said huskily, 'That is the key of the wine-cooler. You will find plenty of brandy there.'"

French writer Émile Zola's novel The Drinking Den (L'Assommoir) includes a character – Coupeau, the main character Gervaise's husband – who has delirium tremens by the end of the book.

American writer Mark Twain describes an episode of delirium tremens in his book The Adventures of Huckleberry Finn (1884). In chapter 6, Huck states about his father, "After supper pap took the jug, and said he had enough whisky there for two drunks and one delirium tremens. That was always his word." Subsequently, Pap Finn runs around with hallucinations of snakes and chases Huck around their cabin with a knife in an attempt to kill him, thinking Huck is the "Angel of Death".

One of the characters in Joseph Conrad's novel Lord Jim experiences "DTs of the worst kind" with symptoms that include seeing millions of pink frogs.

English author M. R. James mentions delirium tremens in his 1904 ghost story "'Oh, Whistle, and I'll Come to You, My Lad'". Professor Parkins while staying at the Globe Inn when in coastal Burnstow to "improve his game" of golf, despite being "a convinced disbeliever in what is called the 'supernatural'", when face to face with an entity in his "double-bed room" during the story's climax, is heard "uttering cry upon cry at the utmost pitch of his voice" though later "was somehow cleared of the ready suspicion of delirium tremens".

In the 1945 film The Lost Weekend, Ray Milland won the Academy Award for Best Actor for his depiction of a character who experiences delirium tremens after being hospitalized, hallucinating that he saw a bat fly in and eat a mouse poking through a wall.[25][26][27]

Writer Jack Kerouac details his experiences with delirium tremens in his book Big Sur.[28]

The M*A*S*H TV series episode "Bottoms Up" (season 9, episode 15, aired on March 2, 1981) featured a side story about a nurse (Capt. Helen Whitfield) who was found to be drinking heavily off-duty. By the culmination of the episode, after a confrontation by Maj. Margaret Houlihan, the character swears off alcohol and presumably quits immediately. At mealtime, roughly 48 hours later, Whitfield becomes hysterical upon being served food in the Mess tent, claiming that things are crawling onto her from it. Margaret and Col. Sherman Potter subdue her. Potter, having recognized the symptoms of delirium tremens orders 5 ml of paraldehyde from a witnessing nurse.

During the filming of the 1975 film Monty Python and the Holy Grail, Graham Chapman developed delirium tremens due to the lack of alcohol on the set. It was particularly bad during the filming of the bridge of death scene where Chapman was visibly shaking, sweating and could not cross the bridge. His fellow Pythons were astonished as Chapman was an accomplished mountaineer.[29]

Irish singer-songwriter Christy Moore has a song on his 1985 album, Ordinary Man, called "Delirium Tremens" which is a satirical song, directed towards the leaders in Irish politics and culture. Some of the people mentioned in the song include former Fianna Fáil leader Charles Haughey, at the time a Labour TD, later the party leader Ruairi Quinn, former Labour Party leader Dick Spring and Roger Casement, who was captured bringing German guns to Ireland for the 1916 Easter Rising.

The Belgian beer "Delirium Tremens," introduced in 1988, is a direct reference and also uses a pink elephant as its logo to highlight one of the symptoms of delirium tremens.[30][31]

In the 1995 film Leaving Las Vegas, Nicolas Cage plays a suicidal alcoholic who rids himself of all his possessions and travels to Las Vegas to drink himself to death. During his travels, he experiences delirium tremens on a couch after waking up from a binge and crawls in pain to the refrigerator for more vodka. Cage's performance as Ben Sanderson in the film won the Academy Award for Best Actor in 1996.

Russian composer Modest Mussorgsky (1839-1881) died of delirium tremens.[32]
