Pemphigoid is a rare autoimmune skin condition that most commonly affects older adults, causing fluid-filled blisters and intense itching that can significantly impact quality of life.

Understanding What to Expect: Prognosis

Learning that you have pemphigoid can feel overwhelming, but understanding what lies ahead can help you prepare both emotionally and practically. The outlook for pemphigoid varies from person to person, and it’s important to approach this information with both realism and hope.

Pemphigoid often follows an unpredictable course. Many people experience periods when the condition is more active, with new blisters appearing frequently, followed by quieter times when symptoms ease. The good news is that pemphigoid can spontaneously resolve on its own, typically within one to five years of onset. However, some individuals may need ongoing treatment for longer periods to keep symptoms under control.^[5][7]

Treatment can effectively control the condition in the majority of patients. Most people see very significant improvement after about three months of treatment. Some fortunate individuals go into long-term remission after initial treatment, while others may need a second round of therapy about a year later. Many people require ongoing management with medication, though often at lower doses than initially prescribed.^[17]

It’s important to acknowledge that pemphigoid can be serious, particularly for older adults or those with other health problems. The condition itself, combined with the powerful medications used to treat it, can lead to complications. Studies have shown that elderly patients with pemphigoid face increased risks, particularly from infections and side effects of corticosteroids (medications that reduce inflammation). High doses of steroid tablets can cause problems including high blood pressure, weakened bones, diabetes, stomach ulcers, and a higher chance of getting infections.^[2][10]

The mortality risk is something your healthcare provider will monitor closely. Research indicates that traditional high-dose oral steroids carry significant risks, including increased mortality, especially in elderly patients with multiple health conditions. This is why modern treatment approaches increasingly favor topical steroids when possible, as evidence shows they may lead to better survival rates compared to oral steroids.^[15]

How the Disease Develops Without Treatment: Natural Progression

Understanding what happens if pemphigoid goes untreated helps explain why seeking medical care is so important. The disease typically begins subtly, which can make early diagnosis challenging.

In most cases, pemphigoid starts with an itchy rash that may persist for weeks or even months before any blisters appear. This early phase, sometimes called the non-bullous stage, can be mistaken for other common skin conditions like eczema (a condition causing red, itchy, inflamed skin) or urticaria (hives). The rash may appear as itchy red patches, raised bumps, or red welts that look like nettle rash. This intense itching often starts before visible blisters form and can be one of the most troublesome symptoms.^[2][5]

Eventually, the condition progresses to what doctors call the bullous phase. During this stage, large, tense blisters filled with fluid begin to appear on the skin. These blisters are quite distinctive—they’re firm and don’t break easily, unlike some other blistering conditions. The fluid inside is usually clear, though it can sometimes contain blood. The blisters most commonly develop in areas where the skin folds, such as the armpits, groin, inner elbows, hands, feet, and abdomen. In severe cases, blisters can appear all over the body.^[1][3]

As more fluid builds up inside the blisters, they become larger and more tense. Eventually, they burst, leaving behind raw, painful areas of skin. These open sores are particularly concerning because they create an entry point for bacteria and other microorganisms that can cause infection. Without proper wound care and treatment, these areas can become seriously infected.^[5]

About a quarter of people with bullous pemphigoid develop blisters or sores inside their mouth. When this happens, eating and swallowing can become extremely painful. Some individuals may also develop a rare variant called mucous membrane pemphigoid, where blisters appear primarily in moist areas of the body, including the mouth, eyes, nose, throat, and genital area.^[1][5]

Left completely untreated, the immune system continues its misguided attack on the skin, leading to ongoing cycles of blister formation and rupture. The constant presence of open wounds significantly increases the risk of serious infections. For older adults or those with weakened immune systems, these infections can become life-threatening, potentially leading to sepsis (a dangerous whole-body response to infection).^[2]

Possible Complications: What Can Go Wrong

While pemphigoid itself is challenging, various complications can arise that make the situation more serious. Understanding these potential problems helps explain why close medical supervision is essential.

Skin infections represent one of the most common and dangerous complications. When blisters break, they leave areas of raw, exposed skin that are vulnerable to bacterial invasion. What starts as a surface infection can potentially spread deeper into tissues and even into the bloodstream. Sepsis, a life-threatening condition where infection spreads throughout the body, is a particularly serious risk for older patients or those with other health conditions. Healthcare providers watch carefully for signs of infection, including increased warmth around wounds, spreading redness, pus formation, or fever.^[2][5]

The medications used to treat pemphigoid, while necessary, carry their own risks. Steroid tablets, which are often prescribed to bring the condition under control, can cause numerous side effects. Your bones may become weaker, increasing the risk of fractures—a condition called osteoporosis. Blood sugar levels may rise, potentially leading to diabetes. Blood pressure can increase, putting strain on the heart and blood vessels. The stomach lining may develop ulcers, causing pain and bleeding. Perhaps most concerning, steroids suppress the immune system, making you more vulnerable to infections.^[2][10]

When pemphigoid affects the eyes, a particularly serious complication can develop. Scarring in the eyes can occur if blisters form in this delicate area, potentially leading to vision problems or even vision loss. This is why individuals with eye involvement need close monitoring by an eye specialist. Similarly, when blisters occur in the mouth or throat, eating and swallowing become difficult. Some people develop difficulty swallowing, called dysphagia, which can lead to weight loss and malnutrition if not properly managed.^[2][6]

Some medications have been reported to trigger pemphigoid, particularly certain diabetes medications called gliptins and cancer treatments known as checkpoint inhibitors. If you’re taking any of these medications and develop pemphigoid, your doctor will need to carefully consider whether to continue, adjust, or stop the triggering drug.^[6][13]

Less commonly, pemphigoid has been associated with other health problems. Some patients may have an underlying malignancy (cancer), though this connection isn’t fully understood. Rarely, people with bullous pemphigoid can develop acquired hemophilia, a bleeding disorder caused by antibodies attacking blood clotting factors.^[6][13]

Impact on Daily Life: Living with Pemphigoid

Pemphigoid doesn’t just affect your skin—it can touch nearly every aspect of daily living. Understanding these impacts can help you and your loved ones prepare for the adjustments that may be necessary.

Physical activities often become challenging. The blisters and sores can be painful, making movement uncomfortable. Simple tasks like walking, sitting, or using your hands may hurt, depending on where blisters appear. Many people find they need to modify their clothing choices, opting for soft, breathable fabrics that won’t irritate fragile skin. Tight clothes or rough textures can cause new blisters to form or existing ones to rupture. Some individuals carry dressings and medical supplies with them in a discreet bag, ready to address any unexpected problems that arise during the day.^[22]

Personal hygiene requires extra care and attention. Bathing needs to be gentle—scrubbing must be avoided, as it can damage fragile skin and cause new blisters. Many people switch to mild, non-irritating cleansers and pat their skin dry rather than rubbing with a towel. If you have mouth sores, oral care becomes particularly important yet painful. Soft toothbrushes, gentle brushing techniques, mint-free toothpaste, and alcohol-free mouthwashes can help manage oral hygiene without causing additional discomfort.^[20]

Eating can become a significant challenge, especially when blisters affect the mouth or throat. Foods that are spicy, acidic, crunchy, or very hot can irritate sores and cause intense pain. Many people find they need to avoid items like citrus fruits, tomatoes, hot sauces, chips, nuts, and steaming hot beverages. Instead, they rely on soft, bland foods that are easier to tolerate. Some individuals need longer periods to finish meals, and in severe cases, nutritional support may be necessary to prevent weight loss and malnutrition.^[20]

Work life may require adjustments. Depending on your occupation, you might need to reduce hours, modify job duties, or take medical leave during flare-ups. Jobs requiring physical labor, contact with the public, or exposure to irritants may become temporarily impossible. The fatigue that often accompanies chronic illness, combined with discomfort from blisters and side effects from medications, can make it difficult to maintain previous levels of productivity.^[19]

Social and emotional well-being often suffer. Visible blisters or scars may cause embarrassment or self-consciousness, leading some people to withdraw from social activities. The chronic nature of the condition, with its unpredictable flare-ups and remissions, can cause significant stress and anxiety. Depression is not uncommon among people living with chronic skin conditions. The constant pain and itching can disrupt sleep, which in turn affects mood, concentration, and overall quality of life.^[19]

Many patients report that managing pemphigoid feels like a full-time job. There are medications to take on schedule, wounds to dress and care for, medical appointments to attend, and constant vigilance to prevent infections. The need to avoid certain triggers—such as sun exposure, heat, or specific foods—requires ongoing attention and planning.^[19]

Support for Family: Helping Your Loved One Navigate Clinical Trials

If your family member has pemphigoid, you may wonder how to best support them, particularly when it comes to exploring treatment options through clinical trials. Your role as a family member or caregiver can be invaluable.

Clinical trials are research studies that test new treatments or new ways of using existing treatments. For pemphigoid, these might include testing newer medications like biological therapies, which target specific parts of the immune system. Some recent studies have explored treatments such as rituximab (which depletes certain immune cells), dupilumab (which blocks inflammatory signals), and omalizumab (which targets allergic antibodies). Understanding that these trials exist gives hope that better, safer treatments may become available.^[14]

The first way families can help is by staying informed. Learn about pemphigoid alongside your loved one. Understanding the disease, its symptoms, and treatment options helps you have meaningful conversations with healthcare providers and ask relevant questions. When your family member feels overwhelmed or tired, you can help ensure important information isn’t missed during medical appointments.

Help your loved one research clinical trial opportunities. Various registries and organizations maintain databases of ongoing trials. The International Pemphigus and Pemphigoid Foundation (IPPF) is an excellent resource that provides information about current research studies. Looking at these resources together can help identify trials that might be appropriate. Keep notes about eligibility criteria, locations, and contact information for trials that seem promising.

Practical support matters enormously. If your family member decides to participate in a trial, they may need transportation to research centers, which could be far from home. Clinical trial visits are often more frequent than regular medical appointments, and the schedule can be demanding. Offer to drive, accompany them to appointments, or help arrange transportation. Having someone there to take notes during complex medical discussions can be incredibly helpful.

Emotional support is equally crucial. Clinical trials involve uncertainty—the treatment being studied may not work, or it might have unexpected side effects. Your loved one may feel anxious about trying something new or guilty about the time and energy required for participation. Listen without judgment, validate their feelings, and remind them that exploring all options, including trials, is a brave and reasonable approach to managing their health.

Help with daily tasks becomes even more important during clinical trial participation. The additional medical visits, combined with potential side effects from experimental treatments, can be exhausting. Assistance with household chores, meal preparation, medication management, and wound care can significantly reduce your loved one’s burden.

Be an advocate. Healthcare systems can be complex and overwhelming, especially when dealing with clinical trials that involve additional paperwork, insurance questions, and coordination between research teams and regular doctors. Help your family member navigate these systems. Make phone calls, organize medical records, and ensure all healthcare providers are communicating effectively about the patient’s care.

Remember that participating in a clinical trial is ultimately your loved one’s decision. Your role is to support their choice, whatever they decide. Some people feel empowered by participating in research that might help others in the future, even if it doesn’t help them personally. Others prefer to stick with established treatments. Both choices are valid and deserve respect.

Finally, don’t forget to take care of yourself. Caring for someone with a chronic illness is demanding. Make sure you’re getting adequate rest, maintaining your own health, and seeking support when you need it. Support groups exist for caregivers too, and they can provide valuable strategies and emotional support as you help your loved one navigate their health journey.
