Blistering Disorders

Blisters that keep coming back, mouth sores that will not heal, or raw patches that slowly spread are not something to treat with a cream bought over the counter. Pemphigus vulgaris, bullous pemphigoid and the other autoimmune blistering diseases are uncommon, serious, and treatable once they are correctly identified. This sits under medical dermatology at Venus Aesthetics, so the first step is diagnosis, usually a skin biopsy, not a prescription. Dermatology appointments are Rs 3,500 and are booked in advance.

What it is

Understanding Blistering Disorders

Blistering disorders are conditions where the immune system attacks the proteins that hold skin cells together, or that anchor the skin to the layer beneath. In pemphigus vulgaris the attack happens inside the upper skin, so blisters are soft, break quickly and leave raw, painful areas, often starting in the mouth. In bullous pemphigoid the attack is deeper, so blisters are tense and fluid filled, itching is usually severe, and it is more common in older adults, generally past sixty. Other autoimmune blistering diseases, including pemphigus foliaceus, mucous membrane pemphigoid and dermatitis herpetiformis, behave differently again. They look alike to the eye, which is why a biopsy, not appearance, settles the diagnosis.

Signs we treat

Come in if you recognise any of these

  • Blisters that are tense and very itchy, or soft ones that burst almost as soon as they appear
  • Mouth ulcers or sore gums that have not healed for weeks and make eating painful
  • Raw, weeping patches that keep returning in the same places
  • An itchy, hive like rash that went on for weeks before any blister formed
  • Blisters on the scalp, chest, back, armpits, groin or inner thighs
  • Blistering that began within weeks of starting a new medicine
  • Red, gritty eyes or genital soreness alongside the skin blisters
How we treat it

Your plan, step by step

1

Consultation with a dermatologist

You are seen by a doctor. We go through when the blisters started, where they appear, whether they itch or burn, what medicines you take, and any mouth, eye or genital symptoms. Photographs of earlier flares help. Dermatology at Venus Aesthetics is by appointment only, Rs 3,500, across our 8 branches in Lahore, Karachi, Islamabad, Faisalabad and Gujranwala.

2

Biopsy to confirm what it actually is

Autoimmune blistering diseases resemble each other, and also resemble bullous impetigo, severe insect bite reactions, pompholyx on the hands and feet, and drug reactions. A small skin sample taken under local anaesthetic, sent for routine microscopy and for direct immunofluorescence, is what separates them. We do not commit you to long term treatment on a guess.

3

Baseline tests before treatment starts

Because treatment calms the immune system, we check first: blood counts, liver and kidney function, blood sugar, and screening for tuberculosis and hepatitis B and C, which matters in Pakistan. Antibody levels can be measured where the laboratory offers the test, and they are useful later for tracking the disease.

4

Settling the active disease

The active phase gets the strength of treatment the condition genuinely needs. That may be a potent topical steroid for limited pemphigoid, or oral steroids with a steroid sparing tablet where disease is widespread. Broken skin is dressed, any infection on top is treated, and mouth involvement gets its own plan so you can eat and drink.

5

Tapering to the lowest dose that holds

Once new blisters stop forming, doses come down in planned steps over months. This is where most relapses happen, usually when someone feels better and stops on their own. Your taper is written down for you, and we describe exactly what an early flare looks like so you telephone us instead of waiting.

6

Long term review and joint care

Review continues after the skin clears, both to catch relapse early and to monitor what long term medication does to blood sugar, blood pressure and bone health. Where the mouth, eyes or other areas are involved, we work alongside your physician, dentist or eye specialist rather than in isolation. Call 0311 111 7546 to arrange follow up.

FAQs

Blistering Disorders, answered honestly

What is the difference between pemphigus vulgaris and bullous pemphigoid?
Both are autoimmune, but the immune attack sits at different depths. Pemphigus vulgaris strikes inside the upper skin, so blisters are soft, burst almost as soon as they form, and leave raw areas, frequently in the mouth first. Bullous pemphigoid strikes deeper, so blisters are tense and hold fluid, itching is usually severe, and it mostly affects older adults. The treatments differ, so the distinction matters.
Can pemphigus or pemphigoid be cured?
Honest answer: these are long term immune conditions, so we talk about control and remission rather than cure. With correct treatment most people reach a stage where blisters stop forming, the skin heals, and medication is reduced to the lowest dose that keeps the disease quiet. Some stay well off treatment for years. Relapses do happen, and they respond better when caught early, which is why reviews continue after you feel fine.
I have mouth ulcers that will not heal. Could this be pemphigus?
It could be. Mouth ulcers are often the first sign of pemphigus vulgaris, sometimes months before any blister appears on the skin. Ulcers that keep spreading, hurt while eating, and do not settle after several weeks of ordinary treatment should be assessed by a dermatologist. Many other causes exist, from lichen planus to vitamin deficiency and infection, so bring your dental notes and previous prescriptions with you.
Do I need a skin biopsy, and what does it involve?
For a confirmed diagnosis, yes. Under local anaesthetic the doctor takes a small sample from a fresh blister and usually a second sample from nearby normal looking skin. That second sample goes for direct immunofluorescence, the test that shows where the antibodies are sitting. Blood tests can check antibody levels as well. It takes a few minutes, one or two stitches, and results are explained to you at review.
Are these blisters contagious? Can my family catch them?
No. Autoimmune blistering diseases come from your own immune system, not from a germ, so nobody catches them from you and nothing is passed on by sharing food, bedding or a bathroom. Broken skin can pick up a bacterial infection on top, and that part is treated separately. Impetigo and chickenpox do blister and are contagious, which is one more reason to confirm the diagnosis properly.
Can a medicine cause blistering?
Yes. Bullous pemphigoid can be triggered by certain medicines, including the gliptin group of diabetes tablets and some blood pressure and water tablets. Severe blistering drug reactions also exist and are medical emergencies. Bring every box, strip and prescription you use to the appointment, including anything from a hakeem or bought over the counter. Never stop a prescribed medicine on your own, let the doctor decide.
How long will I need steroids, and are they safe?
Steroids settle the disease quickly, then the dose is reduced in steps over months, often with a second medicine added so less steroid is needed overall. Length depends on how you respond and is decided at review, not promised in advance. Before starting, screening for tuberculosis, hepatitis B and C, blood sugar and blood pressure is standard practice here. Never stop suddenly, an abrupt stop can cause a flare.
A blister has burst. What should I do at home, and when is it an emergency?
Keep the area clean, do not peel off the roof of the blister, use the wash and dressing your doctor prescribed, and stay cool, because heat and sweating in our summers make raw skin worse. Go straight to an emergency department for widespread skin loss, fever, eye involvement, or blistering that stops you eating or drinking. For routine assessment, book an appointment, Rs 3,500, on 0311 111 7546.
