Raccoon eyes as a newly reported sign of Sweet’s syndrome

Raccoon eyes sign (RES) is a newly reported sign of Sweet’s syndrome in two male patients, a 27-year-old man with a 10 day history of upper respiratory tract infection and a 52-year-old man with acute myeloid leukaemia and a history of testicular cancer (Salman et al, 2018). Both cases were successfully treated with methylprednisolone.

What is raccoon eyes sign?

RES (also known as owl eyes or panda eyes) or periorbital ecchymosis is a sign of basal skull fracture as a result of traumatic periorbital haemorrhage, periorbital referring to the area around the eye. It can also be caused by systemic amyloidosis, neuroblastoma and other conditions.

Can conditions affecting the skin cause raccoon eyes?

Yes, RES can be a sign of neonatal lupus erythematosus, lichen planus pigmentosus, chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome (CANDLE), and Sweet’s syndrome.

What does raccoon eyes look like?

RES describes bruising and discoloration around the eyes that looks like the dark circles around a raccoon’s eyes, and may affect just one eye or both. In Sweet’s syndrome, RES has presented as swollen or haemorrhagic plaques (larger raised, reddened or purple skin lesions) around the eyes (Salman et al, 2018).

What causes raccoon eyes in Sweet’s syndrome?

The exact cause of RES in Sweet’s syndrome is unknown. However, Salman et al argue that it could be caused by secondary damage to blood vessels as a result of white blood cells called neutrophils releasing noxious substances, and the thin skin around the eyes being more sensitive to damage (Ibid).

3 Self-Management Tips for Living with Sweet’s Syndrome

Updated 15/10/18.

Sweet’s syndrome: 3 self-management tips.

1. Take good care of yourself. ❤️

  • Immunosuppressants & infection: prednisone, a steroid medication and immunosuppressant, is the most common form of treatment for Sweet’s syndrome (SS). Immunosuppressants are medications that suppress or ‘dampen down’ the immune system and reduce inflammation in the body. This means that your immune system will be weakened and you’ll be at increased risk of developing infection. If you are taking prednisone or another immunosuppressant, try to take good care of yourself and minimize exposure to infection.

Important! Even if your immune system is suppressed, you’ll need to avoid herbal supplements that have been proven to boost the immune system, i.e. increase immune system activity. Some of these include alfalfa, astraglus, chlorella and echinacea. These supplements can interact with certain medications, and they prevent immunosuppressants from working properly. If you have developed your SS secondary to an autoimmune condition, please be aware of the fact that they can sometimes make autoimmune conditions worse, and if the autoimmune condition flares up, then so can your SS. Read more here.

  • Hypersensitivity reaction to infection: some people with SS are hypersensitive to infection, particularly upper respiratory tract infection, e.g. coughs, colds, flu-like illness and flu. This means that if they develop an infection it can trigger their condition. If you are hypersensitive to infection, try to take good care of yourself and if possible, minimize exposure to infection. Read more here.
  • Fatigue: this is a common symptom of both autoimmune and autoinflammatory conditions, including SS. It occurs as a result of the inflammation in the body that these conditions cause. Symptoms of fatigue can include tiredness and exhaustion (the kind that you can’t ‘shake-off’); ‘fogginess’ or slight dizziness, poor memory and concentration (‘brain-fog’); limb heaviness (every movement can be a real effort); flu-like symptoms. If you are having problems with fatigue, please try to get adequate rest, and don’t be too hard on yourself if you don’t have the energy to do what you normally do.

2. Prevent or minimize skin damage. 🤕

Some people with SS are hypersensitive to skin damage and this can cause new skin lesions to develop or make existing lesions worse. This response to skin damage is known as pathergy and is similar to another response called Koebner phenomenon. Read more here.

3. Avoid overexposure to sunlight. 🌞

Overexposure to sunlight or ultraviolet light can sometimes trigger a SS flare-up, but we still aren’t entirely sure why this happens. The most important things to remember are to avoid or minimize the use of sunbeds, protect your skin in the sun and avoid sunburn! Read more here.

Other information.

1. Stress: some people with SS feel that their condition gets worse when they are stressed, and during times of stress, steroid medication may need to be restarted or the dosage increased. Read more here.

2. Hormones: some female members of the Sweet’s Syndrome UK group have stated that their SS starts to get worse around a week before their period. There are some conditions affecting the skin that can get worse around this time due to increased progesterone hormone levels, but no SS research has been conducted to investigate this possibility. However, as SS can be triggered by both pregnancy and the contraceptive pill, a possible hormonal link to SS has been acknowledged, but further research is needed.

Sweet’s syndrome associated with infection due to adult-onset immunodeficiency with anti-interferon-gamma autoantibodies

Image: Talaromyces marneffei, Mycology Online, The University of Adelaide. Accessed 23/09/18.

This is the first reported case of Sweet’s syndrome associated with the fungal infectionTalaromyces marneffei, and the bacterial infection, Mycobacterium abscessus, due to adult-onset immunodeficiency with anti-interferon-gamma autoantibodies (Xu et al, 2018).

What is adult-onset immunodeficiency with anti-interferon-gamma autoantibodies?

Adult-onset immunodeficiency with anti-interferon-gamma autoantibodies is an immunodeficiency disorder mainly found in Southeast Asians that were previously healthy. The exact cause for this disorder is unknown, but may be linked to the genes HLA-DR and HLA-DQ (Chan et al, 2016). It causes the body to produce higher amounts of anti-interferon-gamma autoantibodies – specific immune system proteins that mistakenly target a person’s own tissues – and prevents immune cells called T-lymphocytes (T1) from responding properly (Chan et al, 2016). This weakens the immune system leading to infection. Symptoms commonly include multiple swollen lymph nodes and skin lesions, particularly Sweet’s syndrome and acute generalized exanthematous pustulosis (Phoompoung et al, 2017). There is no standard therapy for adult-onset immunodeficiency with anti-interferon-gamma autoantibodies and treatment depends on what kind of infection is present.

What is Talaromyces marneffei?

In Southeast Asia, T. marneffei is a fungal infection that has been linked to bamboo rats and soil from their burrows, and is most commonly found in patients with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) due to very weakened immune systems (Chan et al, 2016). Fairly recently, it has been associated with adult-onset immunodeficiency with anti-interferon-gamma autoantibodies.

What is Mycobacterium abscessus?

M. abscessus is a bacterium distantly related to the ones that cause tuberculosis and leprosy. It is a nontuberculous mycobacterial (NTM) infection that can be difficult to treat and is often resistant to antibiotics. NTM infection in people who were previously healthy and HIV negative has been associated with adult-onset immunodeficiency with anti-interferon-gamma autoantibodies (Phoompoung et al, 2017).

Case-study.

A 54-year-old Chinese man was admitted to hospital with a 2 month history of recurrent fever and a 1 month history of multiple swollen lymph nodes. There was nothing unusual about his history, apart from eating bamboo rats a year before. He went on to develop painful skin lesions on the face, back of hands, lower legs and feet. The antifungal, fluconazole, and the antibiotic, levofloxacin, were started to treat infection. The patient was also given the steroid, methylprednisone, and thalidomide to treat Sweet’s syndrome. His skin lesions eventually healed, but a new painful lesion developed under the left side of his jaw. He then had a recurrent fever and enlarging neck lymph nodes with swelling and flushing over his neck. These symptoms improved after levofloxacin was replaced with the antibiotic clarithromycin.

On admission, blood tests had shown raised white blood cell count, raised neutrophil (type of white blood cell) count, elevated erythrocyte sedimentation and C-reactive protein (two tests that can show increased levels of inflammation in the body). Test for HIV was negative, but anti-interferon gamma autoantibodies were positive. Bone marrow biopsy was normal. Blood and sputum cultures showed no fungal or bacterial infection. Biopsy of a skin lesion showed lots of neutrophils in the tissues and fluid in the dermal skin layer (uppermost part of dermis), these findings being consistent with Sweet’s syndrome. Biopsy of a lymph node from the right groin showed a yeast/fungal-like organism under microscope. Biopsy of the jaw lesion showed both yeast/fungal-like organisms and acid-fast rods, the latter indicating myobacterial infection. A diagnosis of deep mycosis (fungal infection in deeper tissues) caused by T. marneffei was given, and the mycobacterial infection was identified as M. abscessus.

A Rare Case of Syndrome of Inappropriate Antidiuretic Hormone Secretion Associated with Neuro-Sweet Disease in Myelodysplastic Syndrome

This is the first documented case of neuro-Sweet’s disease (NSD) in a 66-year-old Japanese woman with a 6 year history of myelodysplastic syndrome (MDS), who developed NSD in association with syndrome of inappropriate antidiuretic hormone secretion (SIADH) (Oka et al, 2017).

What is neuro-Sweet’s disease?

NSD is a rare neurological variant of Sweet’s syndrome (SS) that can affect the brain and spinal cord. Read more here.

What is syndrome of inappropriate antidiuretic hormone secretion?

SIADH is a relatively rare condition where the body makes too much of a hormone called antidiuretic hormone (ADH). ADH is produced in a part of the brain called the hypothalamus, and is then released by the pituitary gland at the base of the brain. ADH helps the kidneys to control the amount of water your body loses through the urine. In SIADH, the body retains too much water, leading to abnormally low levels of sodium in the blood (hyponatraemia). This happens as a result of the excess water diluting the blood and lowering the concentration of sodium.

What causes syndrome of inappropriate antidiuretic hormone secretion?

Common causes for SIADH include medication, hormone treatments, surgery under general anaesthesia, brain conditions, and lung disease. Rare causes include a disease of the hypothalamus or pituitary, cancer, and mental disorders.

Case-study.

A 66-year-old Japanese woman with a 6 year history of MDS, a blood cancer known to trigger SS, developed a fever and skin lesions in the form of a rash over both legs (Oka et al, 2017). A biopsy of a lesion showed lots of white blood cells called neutrophils in the tissues and no inflammation of the blood vessels. These findings were indicative of SS. The patient was given the oral steroid, prednisolone, which is the main form of treatment for SS, and this brought her symptoms under control.

The patient was readmitted to hospital 9 months later with a fever and reduced level of consciousness. Blood tests showed raised C-reactive protein (CRP), indicating increased levels of inflammation in the body. White blood cell count (WBC) was low and neutrophil count was borderline/low, despite being raised in most cases of SS (see ‘Additional notes’). No brain abnormalities were detected on MRI scan. Examination of cerebrospinal fluid (CSF), a clear and colourless fluid found in the brain and spinal cord, showed no neutrophils or white blood cells called lymphocytes, but raised protein levels. Bacterial or viral meningitis were suspected, and intravenous (via a drip in the vein) meropenem and acyclovir were commenced. However, the patient’s fever didn’t improve and her level of consciousness continued to deteriorate.

On day 10 in hospital, the patient was found to be negative for HLA-B51, but positive for HLA-B54. HLA-B51 is a genetic marker associated with a similar condition to SS called Behcet’s syndrome (see ‘Further information’), while HLA-B54 is associated with SS, particularly in Japanese patients (Sweet’s Syndrome UK, 2018). Due to neurological involvement, a diagnosis of NSD instead of SS was suggested (Oka et al, 2017). The intravenous steroid, methylprednisolone, was given. The patient’s condition improved and she was then started on prednisolone.

On day 30, the patient developed a fever and her level of consciousness deteriorated again. Tests revealed a low WBC and neutrophil count; CSF showed no lymphocytes or neutrophils, but raised protein levels; greatly elevated levels of interleukin 6 (IL-6) (see ‘Additional notes’); rapidly falling sodium levels in the blood; no kidney, adrenal or thyroid problems; MRI abnormalities – sagittal T1-weighted MRI showing an absence of high intensity signals in the posterior pituitary lobe. As a result of these findings, a diagnosis of SIADH was given, and the NSD was considered to be the most likely cause for this. Prednisolone and cyclosporine were commenced to treat the NSD, cyclosporine having being found to be useful in SS patients who have developed their condition secondary to low-risk MDS. A 3% sodium chloride intravenous infusion was given for the low sodium levels. The patient’s condition improved, and after discharge from hospital on day 70, she remained stable for a year and there was no recurrence of her symptoms.

Additional notes.

Cytokines are proteins and molecular messengers and part of the body’s immune system. The overproduction or inappropriate production of cytokines, known as cytokine dysregulation, can result in disease. Cytokine dysregulation is a factor in SS, and the cytokine IL-6 plays a role in both NSD and SIADH (Oka et al, 2017). In this case, the patient’s IL-6 levels were greatly elevated, and this activates ADH secretion which can induce SIADH.

IN NSD, blood tests often show a raised WBC, including neutrophil count, and a raised CRP. CSF tends to show a slight increase in protein and an increase in the number of lymphocytes or neutrophils (Oka et al, 2017; Sweet’s Syndrome UK, 2018). However, MDS patients can sometimes have a lack of mature cells or neutrophils, and as a result, blood tests or CSF findings are less likely to clearly indicate NSD.

Sterile peritonitis as a rare symptom of Sweet’s syndrome

Links checked 15/01/18.

This is the first reported case of sterile peritonitis, a type of peritonitis not caused by infection, as a symptom of Sweet’s syndrome (SS) (Rajjoub et al, 2017). Peritonitis is inflammation of the peritoneum, the thin layer of tissue that lines the inside of the abdomen.

Case-study.

A 37-year-old female patient who had previously been diagnosed with SS in 1998 had been having repeat episodes of peritonitis. On admission to hospital, she had a 48-hour history of right sided abdominal pain and feeling sick, high temperature, fast pulse rate, low blood pressure, and a raised white blood cell count, including neutrophil count. There was no vomiting, problems with bowel movements, urinary symptoms, or vaginal discharge, and the patient reported that she had never been sexually active. One month prior to admission, her SS had also flared up, which was treated with steroid medication.

It was in 2000 that the patient had first started experiencing abdominal pain, alongside left groin pain and a high temperature. She was treated with antibiotics, and then had a laparoscopy, otherwise known as abdominal ‘keyhole’ surgery. This is a minimally invasive surgical procedure that allows a surgeon to access the inside of the abdomen, while avoiding large incisions. The laparoscopy showed a large amount of pus in the pelvis and abdomen associated with pelvic adhesions. These are fibrous bands between tissues and organs that occur as a result of inflammation or injury. Due to the complexity of the situation, the laparoscopy was changed to ‘open’ or traditional surgery so that the patient’s abdomen could be more thoroughly examined. Her appendix, although it appeared to be normal, was removed. A sample of the pus was sent for analysis, but showed no bacterial growth, i.e. no signs of infection. It was thought that the absence of infection was due to the patient being given antibiotics before surgery.

On a later admission, the patient had another laparoscopy for ongoing lower abdominal pain. Once again, there was a large amount of pus in the pelvis and abdomen, and a subphrenic abscess. This is a collection of pus between the diaphragm, liver, and spleen. There were also extensive adhesions, and as a result of this finding, the patient was started on antibiotics and initially diagnosed with pelvic inflammatory disease (PID) of unknown cause. PID is an infection of the female upper genital tract, including the womb, fallopian tubes and ovaries, and mostly affects sexually active women aged 15 to 24.

As the patient had reported never being sexually active and having a SS flare-up before admission, it was decided that the PID diagnosis was incorrect, and her peritonitis and pus in the pelvis and abdomen were probably SS-associated. Rajjoub et al have hypothesized that this is because neutrophils have the potential to accumulate in the peritoneal cavity causing a widespread reaction and development of pus and adhesions. It was also hypothesized that steroids may have initially worsened the existing problem, but not caused it, by increasing the movement of white blood cells into the peritoneum.

The patient was eventually discharged from hospital with a pelvic drain in place to drain away any further fluid or pus, and antibiotics to prevent infection.

Sweet’s syndrome associated with antiphospholipid antibody syndrome

Links checked 16/01/18.

Sweet’s syndrome (SS) can develop secondary to autoimmune conditions. This is a rare case of SS developing in association with antiphospholipid antibody syndrome (APS) (Alves et al, 2017).

Case-study.

A 55-year-old man developed skin lesions, fever, joint pain in hands, and the inflammatory eye condition, episcleritis. All of these symptoms were consistent with SS.

Blood tests revealed increased levels of inflammation in the body, and a biopsy of a lesion showed SS. The patient also had a stroke, cavernous sinus thrombosis (blood clot in the hollow spaces located under the brain, and behind each eye socket), and was positive for antiphospholipid antibodies. He was then given a diagnosis of SS-associated APS. Unfortunately, the patient did not respond well to steroids, the most common treatment for SS. The medications methotrexate and hydroxychloroquine were started but stopped, due to bone marrow suppression. Treatment with the biologic, infliximab, led to significant improvement.

Are there any other cases of SS developing in association with APS?

Yes. An earlier case of SS-associated APS was reported in a man with multiple pulmonary emboli (blockages in the artery that carries blood from the heart to the lungs) (Cohen, 2007). He was given the steroid, prednisone, which initially worked well, but experienced SS flare-ups when the dosage was reduced. In 2008, Sweet-like lesions were reported in a 37-year-old man with insufficient blood flow to the brain and APS (Tomb et al, 2008).

What is APS?

APS, or Hughes syndrome, is an autoimmune condition where the immune system produces abnormal antibodies called antiphospholipid antibodies (NHS Choices, 2015). These antibodies then target proteins attached to fat molecules (phospholipids), making the blood more likely to clot.

What are the symptoms of APS?

Symptoms of APS include high blood pressure; deep vein thrombosis; stroke; heart attack; pulmonary embolism. The syndrome can also cause other symptoms, which are sometimes mistaken for the symptoms of multiple sclerosis – balance and mobility problems; vision problems; speech and memory problems; tingling or pins and needles; fatigue; repeat headaches or migraines.
