Can vaccination trigger Sweet’s syndrome?

Sweet’s syndrome triggered by vaccination.

There is some medical evidence to show that certain vaccinations can potentially trigger Sweet’s syndrome, but this is incredibly rare, and it is important to take the following information into consideration:

  • Sweet’s syndrome is rare, probably affecting no more than 3 people per 10,000 (Zamanian and Ameri, 2007).
  • It mainly affects adults not children, and only 5% to 8% of cases will be in children (Sharma et al, 2015).
  • In some people, something is needed to trigger the onset of Sweet’s syndrome, but in up to 71% of people with Sweet’s syndrome there is no known trigger (Tam and Ingraffea, 2015).
  • Infection, mainly upper respiratory tract infection, is a more common trigger for Sweet’s syndrome than vaccination. As a result, Sweet’s syndrome tends to be more common in countries where people are more likely to develop infections (Ginarte and Toribio, 2011:120).
  • There have only been 10 cases of Sweet’s syndrome triggered by vaccination reported in medical literature in the past 42 years – globally! In some of these cases, a definite connection between the vaccination and Sweet’s syndrome was not established.
  • Sweet’s syndrome has only been associated with certain vaccinations and not others (see below).

Which vaccinations have been associated with Sweet’s syndrome?

Sweet’s syndrome has been associated with the following vaccinations:

  • Bacillus Calmette-Guerin (BCG or tuberculosis) (Carpentier et al, 2002: 82; Cruz-Velasquez et al, 2016). Two cases. One in 1986, occurring 15 days after vaccination, but the authors of the medical article that reported this did not control the tuberculin (Mantoux) test. One reported in 2002, occurring 10 days after vaccination.
  • Streptococcus pneumonia (Carpentier et al, 2002: 82; Cruz-Velasquez et al, 2016; Pedrosa et al, 2013). Two cases. One reported in 1990, occurring 4 days after vaccination following a splenectomy. One reported in 2013, and the first with the 13-valent conjugate vaccine.
  • Smallpox (Carpentier et al, 2002: 82; Cruz-Velasquez et al, 2016). Two cases reported in 1975, occurring 3 days after vaccination.
  • Influenza (Cruz-Velasquez et al, 2016; Hali et al, 2010, Jovanovic et al, 2005; Tan el al. 2006; Wolf et al. 2009). Four cases. One reported in 2005; in 2006, one case of bullous Sweet’s syndrome following vaccination in a HIV-infected patient; in 2009, neutrophilic dermatosis of the hands occurring 12 hours after vaccination; in 2010, one case of Sweet’s syndrome after H1N1 influenza (swine fluvaccination.

Do vaccinations trigger Sweet’s syndrome because they are toxic, contain toxins or dangerous chemicals?

No, vaccinations do not trigger Sweet’s syndrome because they are toxic, contain toxins or dangerous chemicals, and anyone who tells you this is either lying to you, trying to scare you, or has no understanding of vaccinations or Sweet’s syndrome.

Why do vaccinations trigger Sweet’s syndrome?

Vaccination can trigger Sweet’s syndrome because of hypersensitivity reaction. This is not the same as allergic reaction.

What is hypersensitivity reaction?

Sweet’s syndrome is caused by errors in the innate immune system (the body’s most primitive, ‘hard-wired’ immune system, and a part of the immune system that doesn’t produce antibodies). Because of these errors, in some people with Sweet’s syndrome, their innate immune system responds to antigens (proteins that a part of your immune system called the adaptive immune system sees as a foreign invader and produces antibodies in response to) in a way that it shouldn’t, i.e. is hypersensitive and over-reacts to the presence of infectious, inflammatory, drug, or tumour cell antigens (Bhat et al, 2015: 257; Kasirye et al, 2011: 135). This means that the presence of antigens associated with certain health conditions, medications and vaccinations can potentially trigger Sweet’s syndrome by causing the innate immune system to activate inflammatory cells, particularly white blood cells called neutrophils (Gosheger et al, 2002: 70). This then leads to the symptoms of Sweet’s syndrome.

If I have Sweet’s syndrome should I avoid having vaccinations?

No, most people with Sweet’s syndrome don’t need to avoid having their vaccinations unless they can’t be vaccinated for other medical reasons. However, if the Sweet’s syndrome was initially triggered by a particular vaccination, e.g. influenza, then it would not be advisable to have the same kind of vaccination again.

How do I know if vaccination has triggered my Sweet’s syndrome?

Remember, Sweet’s syndrome triggered by vaccination is incredibly rare, but if it does happen, then symptoms usually develop within hours, days or less commonly, a few weeks after vaccination. Skin lesions sometimes appear at the vaccination site, but this can also happen because of the skin damage caused by having the vaccination (puncture wound from the needle) rather than the vaccine itself. This response is known as pathergy.

Are there other triggers for Sweet’s syndrome?

Yes, and aside from the triggers that have already been mentioned (infection, skin damage, and vaccination), other triggers for Sweet’s syndrome include:

  • Cancer and blood disorders in 15-20% of cases, e.g. solid tumours, and myelodysplastic syndrome which may progress to acute myeloid leukaemia (Chen et al, 2016).
  • Inflammatory bowel disease, e.g. Crohn’s disease and ulcerative colitis (Cohen, 2007).
  • Autoimmune conditions, e.g. rheumatoid arthritis and systemic lupus erythematosus.
  • Medications in up to 5% of cases.
  • Pregnancy in up to 2% of cases. This is probably associated with hormonal changes, but further research is required.
  • Overexposure to sunlight or ultraviolet (UV) light. This can sometimes trigger Sweet’s syndrome, but we are not entirely sure why this happens.

Mindfulness can reduce psychosocial distress in patients with conditions affecting the skin

What is mindfulness?

Taken from the UK mental health charity, MIND (MIND, 2016).

MIND describes mindfulness as:

‘ A technique which can help people manage their mental health or simply gain more enjoyment from life. It involves making a special effort to give your full attention to what is happening in the present moment – to what’s happening in your body, your mind or your surroundings, for example – in a non-judgemental way. Mindfulness describes a way of approaching our thoughts and feelings so that we become more aware of them and react differently to them.’

Can mindfulness help those with conditions affecting the skin to cope better?

Yes. A study by Montgomery et al has shown that mindfulness can help people ‘to reduce the distress associated with social anxiety and avoidance found in many skin conditions’ (Montgomery et al, 2016). This is very important, as those with conditions affecting the skin are at increased risk of developing anxiety and depression, often avoid social situations as a result of the distress that they cause, and can experience disability levels that are the same as those with other long term diseases.

Can anyone be mindful, and are there different ways to be mindful or practice mindfulness?

Yes. Anyone can be mindful, and there are many different ways in which you can practice mindfulness, e.g. by stopping to notice the small everyday things, by practising meditation or yoga, and by watching your thoughts or learning to view them in a different way (NHS Choices, 2016). For more information on how to be mindful, see ‘References’ below and click on the links.

Alternative and nutritional therapies that don’t work, should be used with caution, or avoided completely in patients with Sweet’s syndrome

Reposted on 13/10/16, updated on 25/04/17.

Can alternative or nutritional therapies be used to treat or cure Sweet’s syndrome?

No. There is absolutely no medical evidence to show that Sweet’s syndrome can be successfully treated or cured with alternative or nutritional therapies. However, some of these therapies may be helpful in promoting overall good health and well-being.

Are you sure that alternative or nutritional therapies can’t be used to treat or cure Sweet’s syndrome, or is this simply a lie that ‘Big Pharma’ wants us to believe?

Yes. At present, we are sure that there is no alternative or nutritional therapy that can be used to treat or cure Sweet’s syndrome. However, some people are being lied to, and told that there are natural and alternative cures for Sweet’s syndrome, but that ‘Big Pharma’ doesn’t want them to know about it.

Who or what is ‘Big Pharma’?

‘Big Pharma’ is a term that’s used to refer to the pharmaceutical industry. Some conspiracy theorists believe that doctors, the pharmaceutical industry and the government, are trying to keep us sick and prevent or discourage us from accessing alternative ‘miracle cures’. This is supposedly being done so that we’ll be forced to buy and use the medications that ‘Big Pharma’ produce and sell, which will continue to make them very rich. There is no evidence to support this theory, but it is not unusual for those selling bogus treatments to resort to the ‘Big Pharma’ conspiracy simply to try and back up their false claims. This is done to try and convince you that their treatments really do work, but that ‘Big Pharma’ never wants you to discover this secret truth, because it will negatively affect their profits. If someone does resort to the ‘Big Pharma’ conspiracy to back up their claims, then it’s a red flag and a strong indication that they probably can’t be trusted.

Are alternative and nutritional therapies always safe to use?

Alternative and nutritional therapies are sometimes safe to use, but not always. Some of these therapies are potentially harmful, or could make Sweet’s syndrome worse. Herbal supplements in particular, can cause lots of problems. One real concern is that they can interact with medications or reduce their effectiveness, and sometimes, any interactions that do occur can be dangerous. Before trying an alternative or nutritional therapy, please check with your doctor first.

Alternative and nutritional therapies that don’t work, should be used with caution, or avoided completely in patients with Sweet’s syndrome.

This is list of alternative and nutritional therapies that don’t work, should be used with caution, or avoided completely. Despite this fact, they are still being advocated or sold as treatments or cures for Sweet’s syndrome by alternative therapists, other individuals, and businesses. These treatments include:

  • Acupuncture: no evidence to show that it works, and should be used with caution. This is because the skin damage caused by the treatment, i.e. the skin being punctured by the needles, may trigger the development of new lesions (pathergy). Read more here.
  • Baking soda (sodium bicarbonate): this is being advocated as a treatment for Sweet’s syndrome, myelodysplastic syndromes and leukaemia, and other cancers (in 15-20% of patients, Sweet’s syndrome develops secondary to some form of cancer). This is an incredibly dangerous pseudoscientific claim, i.e. a false or made-up claim that appears to be scientifically-based, but is not. Anyone who makes such claims should not be believed, and treated with caution. Read more here.
  • Change of diet or elimination of dietary toxins: there is no evidence to show that Sweet’s syndrome is caused by diet or dietary toxins, or that a change in diet can directly improve or cure it. Sweet’s syndrome is caused by errors in the innate immune system and involves factors such as hypersensitivity reaction, cytokine dysregulation and genetic susceptibility. Special diets, e.g. alkaline, anti-inflammatory, detox, gluten-free, Palaeolithic, dairy-free, and vegan are not treatments for Sweet’s syndrome, and could increase the risk of nutritional deficiency in some people. If possible, try to avoid a dairy-free diet, particularly a vegan diet, if you have been taking systemic steroid medication for more than 3 months. This kind of diet may be lower in calcium, and if you are taking steroids, it is very important that you meet your daily calcium requirements (Clarys et al, 2014: 1319, 1321, 1324, 1327). This is because you will be at increased risk of developing steroid-induced osteoporosis. You may also need to be careful about nutritional deficiency if you have other types of health condition, are pregnant, or on a low income. In regards to the latter, you might not have that much money to spend on food and may struggle to meet your nutritional needs as a result.
  • Chiropracty and osteopathy: Sweet’s syndrome does often cause joint pain (arthralgia) or joint pain and swelling (arthritis), and can sometimes develop secondary to autoimmune conditions that affect the joints, e.g. ankylosing spondylitis, rheumatoid arthritis, systemic lupus erythematosus, or Sjögren’s syndrome. However, there is no evidence to show that chiropracty or osteopathy can be used to treat or cure Sweet’s syndrome, and if the joints are painful and swollen, osteopathy and chiropracty should be avoided (NHS Choices, 2014; NHS Choices, 2015b). This is because joint manipulation could make symptoms worse. Physiotherapy is completely safe.
  • EAV or bioenergetics: these are tests that involve using electrodiagnostic devices to supposedly determine the cause of a disease by detecting the ‘energy imbalance’ causing the problem, or even cure a condition by correcting this imbalance. These tests and treatments are a scam, and there is absolutely no medical evidence to show that they work. In the United States (US), the importation of EAV devices has been banned. If you are in the US and someone offers you, or refers you for EAV testing, please report them to the relevant authorities.
  • Essential oils: no evidence to show that they work, and should be used with caution when applied to the skin. This is because the oils might cause irritation, potentially triggering the development of new skin lesions. Read more here.
  • Homeopathy: this is being advocated as a treatment for Sweet’s syndrome by some alternative therapists. This is a pseudoscientific claim, and there is no research to support this claim. In fact, in 2010, the House of Commons Science and Technology on Homeopathy stated that homeopathic remedies perform no better than placebos, and that the principles on which homeopathy is based are ‘scientifically implausible’ (NHS Choices, 2015a). Please take this into consideration before choosing to try homeopathy. However, if you do choose to try it, then it is probably safe.
  • Red root (blood root, bloodwort): this is being advocated as a treatment for Sweet’s syndrome by some alternative therapists. There is no evidence to support this claim, and red root should be used with caution, as it may not always be safe to use either orally or topically. When applied to the skin, it could potentially cause the development of new lesions, and should be completely avoided by those with certain health conditions. Read more here.
  • Some other herbs and supplements to be used with caution: there is no evidence to show that the following supplements can be used to treat Sweet’s syndrome. The algae chlorella is not suitable for those taking certain medications and could make the symptoms of autoimmune conditions, and possibly Sweet’s syndrome worse, particularly if the Sweet’s syndrome has developed secondary to an autoimmune condition. Alfalfa, astragalus, echinacea, and oral zinc should also be used with caution. Read more here.

What is the treatment for Sweet’s syndrome?

Additional note.

Sweet’s Syndrome UK does not promote the use of alternative or nutritional therapies. This is because there is no medical evidence to show that these therapies are effective, or sometimes even safe to use in those with Sweet’s syndrome. If anyone does have information that proves that alternative or nutritional therapies can be used to treat Sweet’s syndrome, I will be more than happy to read it. However, only peer-reviewed medical articles and case-studies will be accepted as evidence. The following will not be accepted as evidence: anecdotal evidence and personal stories; testimonials; YouTube videos; information on blogs or websites where there are no references or links to peer-reviewed medical articles or case-studies, or where the author is not willing to provide this information; blogs or websites where someone tries to pass off their feelings or instincts, beliefs or opinions as facts or evidence.

Two neutrophilic dermatoses captured simultaneously on histology (Sweet’s syndrome and neutrophilic eccrine hidradenitis)

Links checked on 2/03/17.

This is the second reported case of Sweet’s syndrome and neutrophilic eccrine hidradenitis occurring in a patient with acute myeloid leukaemia at the same time (Wlodek et al, 2016).

Key points.

  • Sweet’s syndrome (SS) is a rare autoinflammatory (not autoimmune) condition and form of neutrophilic dermatosis (ND), and in 15-20% of patients can be triggered by cancer, including blood cancers.
  • Other forms of ND include neutrophilic dermatosis of the dorsal hands, Behcet’s syndrome, pyoderma gangrenosum, neutrophilic eccrine hidradenitis (NEH), erythema elevatum diutinum, and bowel-associated dermatitis-arthritis syndrome.
  • ND are skin conditions that occur as a result of lots of white blood cells called neutrophils infiltrating the tissues.
  • A number of ND are associated with cancer and their treatment, but more than one kind of ND rarely occurs together in the same patient at the same time.

Case-study.

This is a case of a 72-year-old man who was being treated for acute myeloid leukaemia (AML) with chemotherapy – daunorubicin and cytarabine. Within 48 hours of starting treatment he developed a fever, and two days later, wide-spread non-tender pink plaques (skin lesions that appear in the form of large raised areas) on the limbs and trunk. A skin biopsy showed lots of white blood cells in the tissues – lymphocytes and histiocytoid cells, but mainly neutrophils. Neutrophils had also infiltrated the fatty tissue under the skin, and this is known as panniculitis. All of these finding were consistent with SS. In addition, neutrophils and lymphocytes were also present around the sweat glands, and this is consistent with NEH. NEH is commonly caused by chemotherapy, including cytarabine, but can sometimes occur for other reasons.

The authors of this study have determined that the neutrophilic infiltrate that is found in a patient with SS has the potential to extend around the sweat glands, thus leading to NEH.

What NOT to say to someone with Sweet’s syndrome!

If  you know someone with Sweet’s syndrome (SS), please don’t say the following things to them. Unfortunately, they are things that people with SS hear all too often, and even though a few of them are well-meant, some are incredibly insulting.

What NOT to say to someone with Sweet’s syndrome!

1. ‘But you don’t look sick’ or ‘Are you faking it?’

The commonest symptom of SS is tender or painful skin lesions, but these are often covered up in some way, e.g. with make-up, by hair or clothing. Also, most of the symptoms of SS cannot be seen, but just because you can’t see them, doesn’t mean that someone with SS isn’t very sick or that they’re faking being ill.

2. ‘You should try this new diet or supplement. It can’t hurt to give it a try.’

SS is an autoinflammatory condition caused by errors in the innate system, and there is no special diet or supplement that can correct these errors. Sometimes, a change in diet or certain vitamins and supplements might help to improve overall health, but they are certainly not a replacement for proper medical treatment. Also, some diets and supplements can do more harm than good, and be very costly. For example, restrictive diets can lead to nutritional deficiency and health problems; certain supplements may not be safe to take or interact with medications; special diets and supplements can be something that many people with SS really can’t afford to buy, and their money could be better spent elsewhere.

3. ‘I’m too busy to get ill’ or ‘You need to keep busy and just get on with it!’

NEVER smugly say to someone with SS, ‘I’m too busy to get ill’. Being busy is not a protection against illness, and no matter how busy or in demand you are, illness can still affect you and stop you from doing the things that you want to do at any time. People with SS don’t choose to get ill, and even when they desperately want to just ‘get on with it!’, they can’t. Also, keeping busy isn’t going to make SS go away or lessen its impact, and doing too much can sometimes make symptoms worse.

 4. ‘I wish I had the luxury of being sick so that I could stay at home all day’.

Being sick is not a luxury, and most people with SS would give anything to be well again. They do not enjoy being ill (do you enjoy it?), and can get very frustrated and depressed because they can no longer work or do the things that they once did. In fact, many with long-term SS go through a grieving process where they mourn the loss of the person that they were and the life that they once had.

5. ‘If you learnt to cope better or didn’t get stressed then you wouldn’t be sick’.

As already mentioned, SS is caused by errors in the innate immune system, and at present, there is no evidence to show that it is directly caused by stress. Some people do find that their SS gets worse when they are stressed, but this might happen for a number of different reasons, including their steroid medication being reduced or stopped. However, in others, their condition flares-up when they are not feeling stressed at all. Also, it is ridiculous to expect those with SS to avoid stress completely. Living with SS can be very stressful in itself, and for all of us, stress is part of everyday life.

6. ‘Don’t give in’, ‘Stop complaining’ or ‘Why do you have to be so negative?’

People with SS are not giving in or being negative when they admit to having a bad day or struggling to cope with their condition. They have the right to have a bad day, just the same as anyone else. NO-ONE can be upbeat, positive and optimistic all of the time, and having a moan or rant or even a bit of a cry can sometimes be very healthy. It can help you to release your feelings and reduce emotional stress.

Can medication trigger Sweet’s syndrome?

Updated 03/03/17.

Can medication trigger Sweet’s syndrome?

Yes. In up to 5% of cases, Sweet’s syndrome is triggered by medication (Cohen, 2007). This is known as drug-induced Sweet’s syndrome.

How will you know if your Sweet’s syndrome has been triggered by medication?

In at least 95% of patients with Sweet’s syndrome, their condition is not triggered by medication. However, drug-induced Sweet’s syndrome should be considered if:

  • Your Sweet’s syndrome developed not long after a particular medication was started.
  • Your Sweet’s syndrome has continued to persist for many months or years, even after treatment.

What will happen if your doctor thinks you have drug-induced Sweet’s syndrome?

Unfortunately, there is no special test to tell you whether or not your Sweet’s syndrome is being triggered by medication. However, if it is suspected that your Sweet’s syndrome is drug-induced, your doctor will:

  • Stop the medication that is possibly causing your Sweet’s syndrome. Your Sweet’s syndrome should then start to settle down, but you may still need treatment.
  • Re-introduce the medication (rechallenge) to see if your Sweet’s syndrome flares-up again. Sometimes, your doctor will decide that this is not necessary.

Why does medication trigger Sweet’s syndrome in some people?

Drug-induced Sweet’s syndrome is often caused by hypersensitivity reaction, but it can sometimes happen for other reasons too, e.g. a treatment that increases white cell production, or causes hormonal changes. Read more here.

What is hypersensitivity reaction, and is it the same as allergic reaction?

No. Hypersensitivity reaction is not the same as allergic reaction.

Hypersensitivity reaction.

Sweet’s syndrome is caused by errors in the innate immune system (the body’s most primitive, ‘hard-wired’ immune system, and a part of the immune system that doesn’t produce antibodies). Because of these errors, in some people with Sweet’s syndrome, their innate immune system responds to antigens (proteins that a part of your immune system called the adaptive immune system sees as a foreign invader and produces antibodies in response to) in a way that it shouldn’t, i.e. is hypersensitive and over-reacts to the presence of infectious, inflammatory, drug, or tumour cell antigens (Bhat et al, 2015: 257; Kasirye et al, 2011: 135). This means that the presence of antigens associated with certain health conditions and medications can potentially trigger Sweet’s syndrome by causing the innate immune system to activate inflammatory cells, particularly white blood cells called neutrophils (Gosheger et al, 2002: 70). This then leads to the symptoms of Sweet’s syndrome.

Allergic reaction.

The most common type of allergy is an IgE-mediated allergy. This is an adverse reaction that the body has to a particular substance that is foreign to the body, e.g. a food, pollen, or pet hair, that does not normally cause harm. This substance is known as an allergen (a type of antigen). Allergic reaction occurs when the immune system mistakes an allergen for a foreign invader such as a bacteria or virus. The adaptive immune system then quickly produces allergen-specific immunoglobulin E (IgE) antibodies in response to this, in order to fight the allergen off. Chemicals such as histamine are also produced, with the overall immune response causing the symptoms of allergy.

What medications have been reported to have triggered Sweet’s syndrome?

Medications that have been reported to trigger Sweet’s syndrome include:

Analgesics (non-opioids).

  • Paracetamol (triggered a Sweet’s syndrome-like condition) (Culla et al, 2014).

Antibiotics.

  • Amoxicillin (possibly) (Volpe, 2016).
  • Clindamycin (Cruz-Velasquez et al, 2016).
  • Tetracycline.
  • Doxycycline (Ibid).
  • Minocycline (Cohen, 2007).
  • Nitrofurantoin.
  • Norfloxacin.
  • Ofloxacin.
  • Trimethoprim/sulfamethoxazole.
  • Quinupristin/dalfopristin (Ibid).
  • Piperacillin/tazobactam (Cruz- Velasquez et al, 2016).

Anti-epileptics.

  • Carbamazepine (Cohen, 2007).
  • Diazepam.

Anti-hypertensives.

  • Hydralazine (Cohen, 2007).

Anti-malarials.

  • Chloroquine (Cruz-Velasquez et al, 2016).

Anti-manic agents.

  • Lithium (Xenophontos et al, 2016).

Anti-neoplastics.

  • Bortezomib (Llamas-Velasco et al, 2015).
  • Decitabine (Kasirye et al, 2011: 134).
  • Imatinib mesylate (Cohen, 2007).
  • Ipilimumab (Gormley et al, 2014).
  • Lenalidomide (Cohen, 2007).
  • Obinutuzumab (triggered a Sweet’s syndrome-like condition) (Korman et al, 2016).

Anti-viral drugs.

  • Abacavir (Cohen, 2007).
  • Acyclovir (Cruz-Velasquez et al, 2016).
  • Interferon-α.

Colony stimulating factors.

  • Granulocyte-colony stimulating factor (G-CSF). This is the most common treatment to trigger Sweet’s syndrome (Cohen, 2007).
  • Granulocyte-macrophage-colony stimulating factor (GM-CSF).
  • Pegfilgrastim (Ibid).

Contraceptives.

  • Levonorgestrel/ethinyl estradiol (Triphasil) (Cohen, 2007).
  • Levonorgestrel-releasing intrauterine system (Mirena).

Diuretics.

  • Furosemide (Cohen, 2007).

Immunosuppressants.

  • Azathioprine (Salem et al, 2015). Sometimes, azathioprine-induced Sweet’s syndrome can be confused with azathioprine hypersensitivity syndrome (AHS) (Aleissa et al, 2017). This is a rare adverse reaction occurring a few days to weeks after azathioprine has been given. AHS can sometimes mimic Sweet’s syndrome, and an azathioprine rechallenge is not advised, as it may lead to a severe adverse reaction or even death.

Nonsteroidal anti-inflammatory drugs (NSAIDs).

  • Celecoxib (Cohen, 2007; Oh et al, 2016).
  • Rofecoxib (Cruz-Velasquez et al, 2016).
  • Diclofenac (Cohen, 2007; Gupta et al, 2015).

Platelet aggregation inhibitors.

  • Ticagrelor (Ikram and Veerappan, 2016).

Proton-pump inhibitors.

  • Esomeprazole (Cohen, 2015).
  • Omeprazole.

Psychotropics.

  • Clozapine (Cohen, 2007).
  • Amoxapine (Cruz-Velasquez et al, 2016).
  • Diazepam.
  • Lormetazepam (Ibid).

Retinoids.

  • All-trans retinoic acid (Cohen, 2007; Tam and Ingraffea, 2015).
  • 13-cis-retinoic acid (isotretinoin) (Cohen, 2007).

Sulfa drugs.

  • Sulfasalazine (Romdhane et al, 2016).

Thyroid drugs.

  • Propylthiouracil (Cruz-Velasquez et al, 2016).

Vaccinations.

  • Bacillus Calmette-Guerin (BCG or tuberculosis) (Carpentier et al, 2002: 82; Cruz-Velasquez et al, 2016). Two cases. One in 1986, occurring 15 days after vaccination, but the authors of the medical article that reported this did not control the tuberculin (Mantoux) test. One reported in 2002, occurring 10 days after vaccination.
  • Streptococcus pneumonia (Carpentier et al, 2002: 82; Cruz-Velasquez et al, 2016; Pedrosa et al, 2013). Two cases. One reported in 1990, occurring 4 days after vaccination following a splenectomy. One reported in 2013, and the first with the 13-valent conjugate vaccine.
  • Smallpox (Carpentier et al, 2002: 82; Cruz-Velasquez et al, 2016). Two cases reported in 1975, occurring 3 days after vaccination.
  • Influenza (Cruz-Velasquez et al, 2016; Hali et al, 2010, Jovanovic et al, 2005; Tan el al, 2006; Wolf et al. 2009). Four cases. One reported in 2005; in 2006, one case of bullous Sweet’s syndrome following vaccination in a HIV-infected patient; in 2009, neutrophilic dermatosis of the hands occurring 12 hours after vaccination; in 2010, one case of Sweet’s syndrome after H1N1 influenza (swine fluvaccination.

Sweet’s syndrome triggered by vaccination is so rare (only 10 cases reported in medical literature in the past 42 years) that a definite connection has not been established in all cases. Also, as infection is a more common trigger for Sweet’s syndrome than vaccination, you may be more likely to develop Sweet’s syndrome as a result of not having your vaccinations than having them.

If someone tells you that Sweet’s syndrome is triggered by vaccinations because they are toxic or poisonous, or contain toxins or dangerous chemicals, then they either have no understanding of Sweet’s syndrome or vaccinations, are not telling you the truth or are trying to scare you, and will have no evidence to support their claims. Sweet’s syndrome triggered by vaccination occurs because of errors in the innate immune system, and this part of the immune system responding to antigens in the way that it shouldn’t. It is nothing to do with toxins!

Xanthine oxidase inhibitors.

  • Allopurinol (Polimeni et al, 2015).

Other.

  • X-ray contrast agents (Cruz-Velasquez et al, 2016).
