How Is Ichthyosis Vulgaris Diagnosed
Ichthyosis vulgaris is often mistaken for simple dry and scaly skin, so it can easily go undiagnosed. If applying moisturizer twice a day doesnt help, a dermatologist can diagnose ichthyosis vulgaris by examining the skin and distinguishing the condition from other skin diseases.
Before seeing the doctor:
- Find out if any of your blood relatives have similar skin conditions.
- Take note of when the symptoms first appeared.
- Make a list of any other medical or skin conditions you have, and the medications, vitamins and supplements you are taking.
The doctor might perform a biopsy . Since the disease is inherited in children, the doctor might also order a genetic test.
What Are The Symptoms Of Ichthyosis Vulgaris
Symptoms of ichthyosis vulgaris include:
- Dry, itchy skin
- Thick, rough skin that looks dirty, most noticeably on the palms and soles of the feet
- White, gray or brown scales on the front of the legs, back of the arms, scalp, back or stomach. If scales appear on the face, its mostly on the forehead and cheeks. Sometimes the edges of the scales curl, making the skin feel rough.
- Extra lines on the palms of the hands and the soles of the feet. The lines may run deep in severe cases, causing cracks in the skin. If the cracks are deep enough, an infection may develop.
- Rough bumps on the arms, thighs and buttocks . The bumps are often mistaken for acne blemishes.
- Inability to perspire adequately. This happens in severe cases and can cause overheating .
Many patients dont realize they have ichthyosis vulgaris because symptoms can be so mild. They simply believe their skin is dry, so they apply moisturizer, which can reduce scaling.
Ichthyosis vulgaris tends to get worse during the winter, when cold and dry air can cause symptoms. In the summer, the disease can virtually disappear because of the warm, moist air.
Sometimes patients notice ichthyosis vulgaris symptoms before they are diagnosed with more serious diseases. On the other hand, ichthyosis vulgaris symptoms sometime appear years after patients are diagnosed with more serious conditions.
Treatments Your Physician May Prescribe
To treat the dry, scaly skin of ichthyosis vulgaris, the physician may recommend a topical cream or lotion containing the following:
- Prescription-strength alpha- or beta-hydroxy acids
- Prescription-strength urea
- A retinoid medication such as tretinoin or tazarotene
- High concentrations of propylene glycol
- Isotretinoin, a very strong medication with many potential side effects, usually used in the treatment of severe, scarring acne

Demographics And Clinical Characteristics Of Ichthyosis Subjects
21 individuals with 3 ichthyosis subtypes were included: 13 patients with two forms of ARCI , EI , or NS , ages 10 years, with known genetic mutations . ARCI patients are typically born as collodion babies ,, and have the eventual phenotype ranging from large plate-like scales overlying variable erythema to fine flaky scale and intense erythema ., All LI patients had mutations in TGM1, encoding transglutaminase, which enables stratum corneum crosslinking CIE subjects had a range of mutated genes , particularly encoding proteins of the hepoxilin pathway.,, EI patients display erythema under warty scale all our patients had KRT10 mutations. NS, resulting from mutations in SPINK5,, encoding a protease inhibitor, ranges from milder erythema with unique scaling to generalized erythroderma . Normal skin from healthy individuals as well as lesional and non-lesional skin from moderate-to-severe adults with two common skin disorders, atopic dermatitis and psoriasis , were also included for appropriate comparisons with all polar cytokine pathways . Due to age differences between groups, with ichthyosis being the youngest cohort , all analyses were age-adjusted .
Identifying Eczema Vs Psoriasis On The Face
According to Dr. Camp, when psoriasis affects the face it often appears on the hairline, in or behind the ear, or on the scalp. Though, it can also occur on the eyebrows and the skin surrounding the nose. The patches or plaques are often well defined with sharp borders, he adds. On the face, psoriasis sometimes occurs in association with seborrheic dermatitis, a common skin condition that can also cause red or pink scaly patches.
Conversely, he says that eczema on the face is more common on the eyelid skin or around the mouth, often as a result of a contact dermatitis. Prolonged eczema around the eyes can make the skin look wrinkled and discolored, a phenomenon sometimes referred to as ‘allergic shiners.’
Given the similarities, Garshick admits that it can be especially challenging to distinguish between eczema and psoriasis on the face. That said, she points out that the biggest hints are that eczema favors the area or around the eyes and mouth, while psoriasis favors the forehead, extending from the brows to the hairline, sometimes covering everything in between.

Eczema Vs Psoriasis: Key Differences
Now that you know that both eczema and psoriasis can be itchy and inflamed, you might be scratching your head wondering what exactly sets them apart then. To help break it down, weve listed out the key differences, below.
Anaptysbio Reports Imsidolimab Poplar Phase 2 Clinical Trial In Moderate
- Imsidolimab treatment did not demonstrate statistically significant improvement over placebo in PPPASI change from baseline at week 16 primary endpoint
- Imsidolimab was generally well tolerated and no serious or severe adverse events were reported in the drug arm of the trial
- AnaptysBio does not currently plan to conduct further clinical development in PPP
- Advancement of imsidolimab to continue across 5 other distinct indications, including anticipated advancement into Phase 3 trial in generalized pustular psoriasis in mid-2021
SAN DIEGO, March 08, 2021 — AnaptysBio, Inc. , a clinical-stage biotechnology company developing first-in-class antibody product candidates focused on emerging immune control mechanisms applicable to inflammation and immuno-oncology indications, today announced that top-line data from its Phase 2 clinical trial of imsidolimab for the treatment of moderate-to-severe palmoplantar pustulosis , also known as the POPLAR trial, failed to meet its primary endpoint.
While further clinical development in PPP is not currently anticipated, AnaptysBio will continue development of imsidolimab in five other immuno-dermatological indications, including GPP, EGFRi-mediated skin toxicity, ichthyosis, hidradenitis suppurativa and acne. Initiation of a Phase 3 clinical trial in GPP is anticipated during mid-2021 following completion of protocol alignment with the FDA.

Appearance Of The Skin Lesion
The skin appearance of in case of eczema may resemble that of psoriasis, but they do have evident differences that set them apart from each other. Eczema is described as dry skin that may appear to be small blisters or raised spots. It is also coupled with excessive itching. On the other hand, psoriasis is rough, red and raised skin, which can be itchy too. The main difference between eczema and psoriasis is that the latter is characterized by scaly flaking that may often cause skin bleeding.
What Happens When You Dont Keep Eczema Moisturised
People with eczema need to keep their skin well moisturised by using emollients at least twice a day. Emollients are used to treat eczema and a good skin care routine, using emollients for both washing and moisturising the skin, soothes, protects and repairs the skin barrier, which can also help reduce itch and eczema flares. If a person with eczema does not moisturise, their skin will be constantly dry and itchy, it could also crack and infection could become a complication. Dry skin is always itchy skin, which is scratched and then damaged, which results in an eczema flare.

What Is Harlequin Ichthyosis And Is It Serious
Harlequin ichthyosis is a rare form of ichthyosis that is present at birth. A newborn with the condition will have thick plates of skin that crack and split apart. Eating and breathing may be difficult, and infection may occur.
In the past, it was difficult to survive more than a few days with this condition. Now, however, treatment is available. If applied immediately, it can be effective. Some children with harlequin ichthyosis are already living into their teens and 20s.
Most cases of ichthyosis vulgaris are caused by a mutation in the gene responsible for encoding filaggrin. This is a protein that helps create the skins natural barrier.
Without an effective barrier, the skin struggles to retain moisture and a consistent pH.
Chronically dehydrated skin cells begin to thicken and harden as they age. They then move to the surface of the skin, where they become fixed scales.
A vast majority of ichthyosis cases are inherited. Individuals with one copy of the abnormal gene tend to have milder cases than those with two copies.
The condition can also be caused by:
- the use of certain medications
- systemic conditions
- conditions that affect the entire body
Common causes of acquired ichthyosis include:
- impaired thyroid function
Ichthyosis vulgaris causes extremely dehydrated skin resulting in thick and scaly skin.
The most commonly impacted regions of the body include:
- extensor region of the limbs, especially the elbows and shins
- face, typically the forehead and cheeks
What Is The Difference Between Ichthyosis And Psoriasis
The disorder has long baffled scientists, Paller said. However, her team’s research may have identified the underlying cause of ichthyosis, and it’s similar to what drives a far more common skin condition — psoriasis. Like ichthyosis, psoriasis is associated with an overactive Th17 pathway.
One may also ask, what is the best treatment for ichthyosis? Treatments may include: Exfoliating creams and ointments. Prescription creams and ointments containing alpha hydroxy acids, such as lactic acid and glycolic acid, help control scaling and increase skin moisture.
Accordingly, what causes ichthyosis?
Ichthyosis vulgaris is commonly caused by a genetic mutation that’s inherited from one or both parents. Children who inherit a defective gene from just one parent have a milder form of the disease. Those who inherit two defective genes have a more severe form of ichthyosis vulgaris.
Does ichthyosis go away?
Most have a normal lifespan. Ichthyosis vulgaris also can become less serious with age. Most people, however, need to continue treating their skin for life. If the disease can be cured, the ichthyosis may go away.

When To Seek Medical Care
If your child continues to have very dry, scaly skin despite twice daily application of an over-the-counter moisturizer, be sure to tell his/her pediatrician.Any adult who develops dry, scaly skin that is not improved by twice daily application of an over-the-counter moisturizer should see a physician for evaluation.
Skin Infections Or Infestations
Skin can be infected by a wide variety of bacteria, viruses or fungi. Symptoms can range from mild to severe:
- Bacterial infections organisms enter the skin through a hair follicle, an insect bite or a cut symptoms begin as small red bumps that slowly increase in size
- Viral skin infections such as measles or chickenpox cause a mild to severe rash and fever
- Fungal infections usually develop in moist areas of the body such as the feet or underarms some are contagious but arent life-threatening
- Parasitic skin infections tiny insects or organisms burrow underneath the skins, lay eggs and cause a burning itching rash on skinbed bugs and scabies fall into this category

What Causes Ichthyosis Vulgaris
Ichthyosis vulgaris results from loss-of-function mutations in the gene encoding the protein filaggrin , which is mapped on the epidermaldifferentiation complex on chromosome 1q21. The mutations lead to defective production of filaggrin.
Filaggrin is a filament-associated epidermal protein required for the binding of keratin fibres in epidermal cells, to form an effective skin barrier. It helps maintain the skin pH, retain moisture in the stratum corneum, and reduce trans-epidermal water loss .
Xerosis or dryness results from the reduced skin hydration associated with defective filaggrin. Excessive scale results from the inability of the squames to remain hydrated as they move upward through the stratum corneum. Hyperkeratosis results from compensatory repair mechanisms increasing cell proliferation.
There Can Be Overlap Between Eczema And Psoriasis
Still in some children, its hard to tell the difference. In this case, a dermatologist might diagnose the child with psoriasiform dermatitis.
Sometimes, a child has both eczema and psoriasis, so there can be some overlap.
A dermatologist, however, will generally be able to differentiate between these two relatively common skin disorders.

Identifying Eczema Vs Psoriasis On The Body
Remember: Eczema typically falls within joint folds, while psoriasis congregates just about anywhere, though most commonly on the knees, elbows, and scalp. However, if you have inverse psoriasis , Gmyrek says that you may also find psoriasis scales in groin folds, under the arms, and below the breasts. Additionally, if you notice little dents in your nails, that could also be a sign of psoriasis.
Beyond location, Dr. Camp points out the eczema is much less defined than psoriasis. So, if you notice dry patches without redness or a raised silhouette, eczema is most likely more to blame. However, remember that only a doctor can officially deem it so.
The most definitive way to distinguish the two is with a skin biopsy, although there are scenarios when even that is not conclusive to differentiate the two,Garshick says.
What Is The Itch Scratch Cycle
Dry skin is always itchy, which will then be scratched, which results in a flare . Constant scratching leads to damage, broken skin, which becomes wet and weepy due to infection. This is known as the itch-scratch-damage-cycle the first point at stopping this cycle from developing is to keep eczema well moisturised to prevent dry and itchy skin. This dry, flaky and scaly skin is unsightly, and the itch, discomfort plus embarrassment can lead to reduced self-confidence and affect quality of life for many people3.

How Is Psoriasis Treated
The type of psoriasis and the severity of the individual’s psoriasis will help to determine what course of treatment will be appropriate. There are a variety of topical treatments that may help improve symptoms of psoriasis, including topical corticosteroids. Other ways to manage and treat psoriasis symptoms include light therapy , systemic treatments, biologics, other medications, lifestyle modifications or alternative and complementary therapies.3
Ichthyotic Skin Shows A Th17
To evaluate primary Th1, Th2, Th9, Th17, Th22 cytokines and some epidermal markers, which are often below detection levels on gene-arrays, we performed qRT-PCR. We observed large increases in expression of general inflammatory and some innate immune markers in ichthyosis compared with control skin . These increases were comparable and even higher than those in AD and psoriasis. Interestingly, TNF was up-regulated in AD and psoriasis compared to controls, but not in ichthyosis, although higher levels were seen in NS, as reported .,, Expression of Th1-related markers was also increased in ichthyosis compared to controls . The expression of Th2 cytokines was lower in ichthyosis than in AD, and largely similar to controls . Some Th2 markers showed increases in NS, but much smaller than in AD and comparable or even lower than in psoriasis . IL-9/Th9 cytokine was not increased in ichthyosis compared with controls .

What Is The Difference Between Eczema And Psoriasis
Eczema and psoriasis are separate skin conditions, most people have either eczema or psoriasis but a small number of people have both. They are both skin conditions with defects in the immune system and skin barrier but the immune pathways are different. Eczema affects the skin barrier , as the skin is not able to produce as many fats and oils which results in being less able to retain water. This means the skin, as a protective barrier, is compromised and gaps open up between the skin cells and moisture is lost through the skin from the deeper skin layers. This allows bacteria, irritants and allergens to pass through the skin, which irritates the skin and causes eczema to flare.
In psoriasis the stratum corneum is affected in an opposite way, it is thickened, as the skin replacement process speeds up, taking just a few days to replace skin cells that usually take 21-28 days. This accumulation of skin cells builds up to form raised plaques on the skin, which can also be flaky, scaly, red on Caucasian skin, darker patches on darker skin tones.
Eczema and psoriasis can both affect any part of the body, classically eczema is seen on skin creases and psoriasis on outer parts of skin , both conditions are itchy.
