Dear Doctor: I’m 27 years old and have itchy skin that my doctor says is psoriasis. It’s not all the time -- it comes and goes. Sometimes it’s bad, and other times it’s not that noticeable. I’ve heard that what you eat matters. Can my diet help prevent or control the condition?

Dear Reader: Psoriasis is a chronic skin condition associated with a malfunction of the immune system. It is marked by the overproduction of skin cells, which results in raised areas of dry, reddened and flaking skin. These areas of inflammation, which are sometimes topped by silvery scales, most often appear on the elbows, knees and scalp. However, they can occur anywhere on the body. Additional symptoms can include burning, soreness and itching; nails that grow thicker than normal or develop pits or ridges; and stiffness or swelling in the joints. Susceptibility to psoriasis, which occurs in both women and men, is inherited. The condition is much more common in adults than in children.

The reasons that the immune system goes a bit haywire aren’t yet fully understood. However, flares are associated with triggers such as physical or emotional stress, cold weather, the use of tobacco products and skin injuries. And you are correct that some studies have found that diet may also play a role.

Research suggests that avoiding inflammatory foods may help ease some psoriasis symptoms and lessen the frequency of flares. Chief among the culprits is sugar, which has long been linked to inflammation. In a mouse study published last year in the Journal of Investigative Dermatology, researchers were able to trigger inflammatory changes in the skin in just a few weeks on a high-sugar diet. Other foods that have been linked to inflammation include alcohol, red meat, saturated fats and the highly refined carbohydrates found in snack foods and ultra-processed foods.

What you do eat can be just as important. Some studies have found that the so-called Mediterranean diet, with its focus on fish, seafood and olive oil, as well as a wide range of fresh vegetables, fruit and leafy greens, may also improve symptoms. These fish-forward diets are rich in n-3 polyunsaturated fatty acids, which are also known as omega-3 fatty acids. These types of fats appear to have an influence on something known as eicosanoids, which are molecules that play a role in causing inflammation. With an increase of omega-3 fatty acids in the diet, researchers suspect that inflammatory processes may be suppressed.

Diet alone has not been found to either control or cure psoriasis, so it’s important that you follow the treatment plan outlined by your doctor. And when it comes to food, the responses to dietary changes in people living with psoriasis are highly individual. Some patients have found that a vegetarian diet can lessen the severity of their condition. Others have reported an increased sensitivity to gluten. Pay attention to what you eat, and note whether or not it appears to consistently correspond to changes in your level of inflammation. You may uncover some personal dietary triggers that can help you in managing your condition.

Aortic Regurgitation Often Symptom-Free When Mild

Dear Doctor: I am a 72-year-old man and have been diagnosed with aortic regurgitation. My cardiologist said since I’m not experiencing any of the usual symptoms connected with this, he thinks I should just continue to monitor it until I do. What can I expect if and when I do start experiencing symptoms?

Dear Reader: Aortic regurgitation is a condition in which the aortic valve in the heart isn’t closing properly. The aortic valve separates the left ventricle, which is the lower pumping chamber of the heart, from the aorta. When functioning properly, it’s a one-way valve that closes completely between heartbeats. As with the other three cardiac valves, the main job of the aortic valve is to maintain the one-way flow of blood through the heart.

When someone has aortic regurgitation, the valve isn’t closing tightly. This allows a portion of the oxygen-rich blood, which the left ventricle had just pushed into the aorta during a heartbeat, to flow back into the chamber as the ventricle relaxes. The leakage interferes with optimal blood flow through the heart and throughout the body.

As a result of inadequate blood flow, which delivers oxygen to the tissues of the body, people with aortic regurgitation can become easily fatigued and out of breath. In order to compensate for the glitch in the system, the heart will begin to work harder. Over time, this can cause the left ventricle to become enlarged. It can also cause a condition known as hypertrophy, which is when the walls of the ventricles thicken due to the extra work they’re being asked to do. These structural changes make the left ventricle less efficient and add to the burden on the heart.

Aortic regurgitation is often symptom-free when it is mild. It is typically detected when a physician listens to the heart and hears the tell-tale sounds of a leaky valve. As the condition begins to worsen, symptoms can include the fatigue and shortness of breath that we mentioned, as well as chest pain, irregular heartbeat, swelling in the feet and ankles and difficulty breathing when lying down. These are what your physician will be looking for. In more severe cases, diastolic blood pressure -- that’s the bottom number -- becomes low and is often accompanied by a forceful heartbeat, known as a “bounding” pulse. Some people may experience severe light-headedness that can lead to fainting.

The decision to monitor your condition without a surgical intervention at this time is known as watchful waiting. In making that choice, a cardiologist weighs a number of factors. These include the severity of the individual’s condition, the appearance of their heart as obtained through scans, and the person’s general health. When someone does need surgery to repair or replace an aortic valve, it can often be done via a catheter that is threaded through a vein. Although this is a minimally invasive procedure, it’s still surgery and, therefore, carries some risks.

If you begin experience any of the more advanced symptoms that we have discussed, it’s important to seek out immediate medical care.

Lupus Treatment Often Requires Many Medications

Dear Doctor: My daughter got a rash across her cheeks that we thought was an allergy. A year later, she was diagnosed with lupus. She’s only 17, and the doctors keep putting her on different meds, which worries her dad and me. I’ve been reading that ginger can be helpful. What do you think?

Dear Reader: Lupus is what is known as a chronic autoimmune disease. That means it’s a long-term condition in which the immune system, which isn’t behaving properly, has begun to attack the body’s own tissues. There are several forms of the disease, but the most common is systemic lupus, which can affect the joints, skin and certain internal organs, including the heart and kidneys.

Although anyone can develop the disease, about 90% of people with a form of lupus are female. It usually appears between the ages of 15 and 44, which are a woman’s reproductive years. Genetics plays a part, and people who have a family member with lupus, or another kind of autoimmune disease, are at higher risk of developing it. It’s also more common in people of African American, Native American, Asian, Latino and Hispanic descent.

The rash that you noticed on your daughter’s face is one of the classic signs of a flare, or episode, of systemic lupus. Known as a butterfly rash, it looks somewhat like a localized sunburn that affects the upper cheeks and spreads across the bridge of the nose. Additional symptoms can include fatigue; swelling, pain or stiffness in the joints; chest pain; dry eyes; and other types of rashes.

Treatment consists of managing symptoms, which, as you have discovered, can require a number of medications. They address issues such as blood clots, inflammation, immune system response, fluid retention, infections and high blood pressure. Each case of lupus is different, with different levels of severity and varying symptoms. As a result, a shifting range of medications can be required. This can be daunting, and even alarming, and we encourage you to discuss your concerns with your daughter’s rheumatologist.

As to your question about ginger, there’s an interesting new study led by researchers from the University of Michigan. When they looked into the effects of 6-gingerol, the main bioactive compound in ginger, they found evidence it inhibited a specific mechanism associated with abnormal clot formation. Mice that were given 6-gingerol had lower levels of sticky, weblike proteins known as neutrophil extracellular traps, or NETs. These play an important role in immune function. In autoimmune diseases, however, NETs become overactive. After giving the mice 6-gingerol, the researchers noted that the formation of blood clots was markedly reduced.

While this research is exciting, and even encouraging, it’s only an early step in a long process. More research is needed in animal models, and then, if that continues to be promising, with humans. In the meantime, your daughter should continue to make regular visits to her rheumatologist and use the medications prescribed. Her doctors will monitor her disease and recommend the treatment protocols that her specific type of lupus requires.
