Children with HS

Chapter contents

I. Introduction

HS is more common after puberty, but younger kids can have it as well. In the United States, girls are more likely to have HS than boys. In pediatric patients with HS, you often find that other close family members also have HS, suggesting there might be genetic factors that contribute to having the disorder.

II. Clinical Features of Children with HS

A good screening question to ask if you are trying to determine if your child has HS is: have they had outbreaks of boils or abscesses during the last six months? Another good question to ask is: did they have at least two boils in one of the following locations: armpits, groin, genitals, under the breasts, buttocks, neck, or abdomen)?

A healthcare provider familiar with HS will be able to make the diagnosis of HS just by taking a medical history and examining the skin. No biopsies or lab tests are required.

III. Associated Conditions

Pediatric patients with HS have a higher chance of being obese or overweight, having acne, and having other conditions such as inflammatory bowel disease, inflammatory joint disease, anxiety, and depression. Kids with Down syndrome are at increased risk of HS. Sometimes your healthcare provider will need to do further work-up to rule out other associated diseases.

IV. Treatment of Children with HS

Treating HS is challenging. Unfortunately, treatments have largely not been studied in pediatric patients with HS, and treatment recommendations are taken from adult data. Early interventions might potentially modify disease progression. If inflammation is controlled early and disease severity does not progress, one could expect to prevent complications like scarring, but we need to study this further. Your healthcare provider might decide to start with topical treatments if the severity of the disease is mild; if moderate or severe, oral or injectable medications would be considered. Treatment options include antibiotics, retinoids, hormonal medications, biologics, laser, and surgery among others. As HS is made worse by heat, sweat, and friction, kids sometimes stop doing physical activities. It is important to control HS so they can continue to remain active and healthy.

V. Tips to help your child with HS

It can be helpful to educate your child about HS

The more your child understands about what is happening to their body, the easier it will be for them to talk to their friends about it, ask for help, and make healthy decisions for themselves.

Talking to your child to find out what bothers them most about their HS can also be helpful. As adults, our perceptions and values are different than that of our kids. You may focus on the long term effects of the disease, whereas your child may just be trying to figure out how they can change their clothes for gym class without anyone noticing, or how to apply their skin care while staying overnight at a friend’s house.

Finally, it is important to observe your child for signs of pain or depression and also assess their overall well-being. Pain related to an infection or worsening inflammation may be perceived by your child as “the usual chronic pain” they endure, and they may miss the opportunity to prevent a larger flare. Kids with HS have higher rates of depression. The emotional stress associated with HS can lead to feelings of sadness and hopelessness, causing kids to withdraw from normal activities and relationships. Growing up is challenging, but growing up with a chronic health problem can be overwhelming for some children. It is important to be aware of all the support services available to you and your child, and to encourage your child to talk to someone about their HS and how it affects them. This can happen through a counselor, support group, or even by joining a recommended online support group.

VI. Questions and Answers

Question 1 Will my child grow out of HS? Answer

Not likely. HS is a chronic inflammatory skin condition, meaning it does not go away on its own, but it can be treated. The severity of HS may vary over time. It may go through periods of time when it is not very active, but it can get worse and more severe with time. That is why early diagnosis and treatment are so important. The earlier HS is treated, the less severe it may become.

Question 2 Is HS different in kids than adults? Answer

No. It is the same disease process, but children and teens with HS may be more likely to have hormonal imbalances. Kids should always be screened for hormone-related diseases, such as causes for early puberty, obesity, and metabolic syndrome (including high cholesterol, diabetes, and high blood pressure).

Question 3 Are sports and exercise bad for my child’s HS? Answer

Keeping active is important. The goal is to allow kids to participate in activities they enjoy. Sports are a way for kids to socialize with their peers, and exercise can help kids maintain a healthy weight. However, the sweating and skin friction experienced with some sports may irritate existing HS lesions or create new ones, worsening pain. Ideally, the chosen exercise increases heart rate but minimizes sweat and friction.

Question 4 Can my child participate in age-appropriate activities such as swimming or sleepovers? Answer

Yes! The exercise from swimming is very beneficial. There may also be benefits when swimming in a chlorinated pool. However, a child who is experiencing a flare with open wounds may want to wait until the wounds have healed before swimming. As for sleepovers, absolutely. The more friends and laughter, the better. You may need to explain HS to other parents or your child’s friends, so they understand that your child does not have a contagious disease. Let your child lead as normal a life as possible.

Question 5 Will laser hair removal help my child’s HS? Answer

Some data suggests that laser hair removal in HS patients is helpful. It appears to be most effective in early stages of HS. However, it may not be covered by insurance and can take several treatments, which can be expensive. More information regarding laser treatments for HS can be found in Chapter 24.

Question 6 My relative has severe HS—will my child’s HS be as severe? Answer

While HS can run in families, the severity of disease can vary between family members. Not all people with HS develop severe disease, and for many patients, HS can improve over time if diagnosed and treated early.

Question 7 Is my child contagious? Answer

HS is not an infection. It is not sexually transmitted or caused by poor hygiene. It is an inflammatory skin condition believed to be caused by an overactive immune response. However, HS lesions can become infected with bacteria. It is important to keep those infected areas covered when they are draining, as the bacterial infection (not the HS) could be contagious.
