DPCP is more stable in solution and is usually the agent of choice. Mechanism of action: Topical immunotherapy acts by varied mechanisms of action. The most important mechanism is a decrease in CD4 to CD8 lymphocyte ratio which changes from to after contact immunotherapy. A decrease in the intra-bulbar CD6 lymphocytes and Langerhan cells is also noted. Expression of class I and III MHC molecules, which are normally increased in areas affected by alopecia areata disappear after topical immunotherapy treatment Method of sensitization: The protocol for contact immunotherapy was first described by Happle et al in The scalp is the usual sensitization site.
Patients are advised to avoid washing the area and protect it from sunlight for 48 hours. After 2 weeks 0. The usual concentration of DPCP that ultimately causes mild contact eczema is 0. An eczematous response indicates that sensitization has taken place. It is important to remember that DPCP is degraded by light and should thus be stored in the dark and the patient should also wear a wig or hat during the day after application of DPCP.
DPCP immunotherapy has even been combined with oral fexofenadine treatment with good effect Evaluation of efficacy: The clinical response after six months of treatment is rated as per the grading system proposed by Mcdonald Hull and Norris Grade 3- Regrowth of terminal hair with patches of alopecia.
If no regrowth is observed within six months of treatment, the patient is considered to be a non-responder. Other reported poor prognostic factors include the presence of nail changes, early onset disease and a positive family history Topical immunotherapy can lead to certain side effects such as persistent dermatitis, painfull cervical lymphadenopathy, generalized eczema, blistering, contact leukoderma, and urticarial reaction. Systemic manifestations such as fever, arthralgia and yellowish discoloration of hair are noted more often with DNCB.
The method of application is the same as with DPCP but the applications are done once or twice weekly Good care should be taken to avoid contact with the allergen by handlers, including pharmacy and nursing staff. Those applying the antigen should wear gloves and aprons. There is no available data on the safety of contact immunotherapy during pregnancy and it should not be used in pregnant women or in women intending to become pregnant.
Yamamoto et al reported in their findings that tacrolimus stimulated hair growth in mice 41 , although subsequent studies have shown conflicting resultsRecently, Price et al reported an patient study in which none of the patients had terminal hair growth in response to tacrolimus ointment 0.
Garlic is a very commonly used home remedy in the treatment of alopecia areata in India and even in the rest of the world. One study analyzed the effect of a combination of topical garlic gel and betamethasone valerate ointment in alopecia areata in a double-blind study. The study found the combination useful in majority of the patients with a statistically significant difference between the treatment and control groups Among topical retinoids, tretinoin and bexarotene have been tried in alopecia areata with mixed results Irritation of the skin is a very common side effect and the efficacy is doubtful in the absence of double-blind randomized trials.
The propensity of certain prostaglandin analogues used as anti-glaucoma eye drops to cause hypertrichosis has been employed in the treatment of alopecia areata. These prostaglandin analogues include Latanoprost and Bimatoprost and they are used in the treatment of alopecia areata involving the eyelashes However, the results obtained with these drugs have not been really encouraging Systemic treatments, as a rule, are used only in progressive forms of alopecia areata and going by the immune nature of the disease, majority of these treatment options are immunosuppressants or immunomodulators in nature.
The use of systemic corticosteroids for the treatment of alopecia areata is under much debate. Some authors support a beneficial role of systemic steroids on halting the progression of alopecia areata, but many others have had poor results with this form of therapy. The suggested dosages are 0. Treatment course ranges from months, but prolonged courses should be avoided to prevent the side effects of corticosteroids.
Side effects profile of corticosteroids in conjunction with the long-term treatment requirements and high relapse rates make systemic corticosteroids a more limited option. In addition to the daily oral administration of corticosteroids, there are several reports of high-dose pulsed corticosteroid treatments employing different oral and intravenous regimens Many of these regimens have been tried in alopecia areata with encouraging results but the majority of these studies have been non-blind open studies.
One such pulsed administration employs a high dose oral corticosteroid on two consecutive days every week with a gap of 5 days between the two pulses. This modality of treatment is known as oral minipulse therapy OMP and it has been tried in many skin diseases in addition to alopecia areata like vitligo and lichen planusSome open label studies on corticosteroid OMP therapy have reported encouraging results in alopecia areata Because of its immunomodulatory and immunosuppressive actions, sulfasalazine has shown good hair regrowth in the treatment of alopecia areata.
The drug is administered orally usually as enteric coated tablets to minimize the gastrointestinal side effects. The treatment is started at a lower dose, usually in the range of mg twice daily and then the dose is gradually increased to 1 g three times a dayAdverse effects include gastrointestinal distress, liver toxicity and haemotological side effects. Sulfasalazine helps in alopecia areata because it causes inhibition of T cell proliferation, and natural killer cell activity and also inhibits antibody production.
A number of clinical studies have documented a positive effect of sulfasalazine in alopecia areata. Azathioprine, being an immunosuppressive agent has also been tried in alopecia areata. The drug is used in many cutaneous disorders owing to its effect on circulating lymphocytes as well as Langerhan cells. This drug has proven effective in the treatment of alopecia areata because of its immunosuppressive and hypertrichotic properties.
The side effect profile and high rate of recurrence render the drug a poor choice for the use in alopecia areata. So the drug is to be attempted only in severe forms of alopecia areata not responding to treatment Methotrexate either alone or in combination with prednisolone has been used in the treatment of alopecia areata in various studies with variable success rates Tumour necrosis factor inhibitors such as Adalimumab, Infliximab and Etanercept have been tried in alopecia areata, but the results have not been encouraging Clinical trials conducted till now have failed to demonstrate the efficacy of any biological agent in alopecia areata.
Several uncontrolled studies regarding PUVA therapy for the treatment of alopecia areata exist. The mechanism of action is considered to be the interference in the presentation of follicular antigens to T-lymphocytes by depletion of the Langerhan cells. The relapse rate following treatment is high, sometimes demanding repeated treatments for a prolonged period with implications for carcinogenic risks To mitigate the side effects of systemic psoralens, PUVA-turban therapy is used for alopecia areata involving the scalp.
In this form of photochemotherapy, very dilute solutions of 8-methoxy psoralen are applied on the scalp by utilizing a cotton towel as a turban. Although narrowband UVB is among the most effective treatment options in a number of immune mediated skin diseases, the same efficacy has not been found in alopecia areata.
Properly designed randomized trials are needed to elucidate whether NBUVB has any role in the management of alopecia areata Excimer laser and excimer light are two more recent additions to the phototherapeutic armamentarium for many skin and hair disorders. While the main use of these phototherapeutic modalities remains to be psoriasis and vitiligo, their immunomodulatory effect can be made use of in many other skin disorders. Some clinical studies have documented the efficacy of excimer laser and excimer light in alopecia areata In one such study, Various non-conventional therapeutic agents have been used in alopecia areata with some degrees of success.
These include fractional Er-Glass laser 77 , topical azelaic acid 78 , topical onion juice 79 , topical 5-fluorouracil ointment 80 and photodynamic therapyThe efficacy and safety of these therapeutic agents need to be confirmed in large-scale, double-blind, placebo-controlled trials before they can be recommended for treatment of alopecia areata.
In this treatment tiny pigment dots of pigment are used on the skin on the region of the eyebrows to mask the underlying alopecia Alopecia areata is now regarded as an autoimmune disease involving the cellular immunity through the CD8 lymphocytes that act on follicular antigens. The pathogenesis of alopecia areata is being unravelled with various animal and human studies.
The localized forms often heal spontaneously or respond to simple treatments such as topical or intralesional corticosteroids. The severe forms have a reserved prognosis and are difficult to treat. In these cases the best results are achieved by topical immunotherapy technique. References Dawber R. Alopecia areata. Monogr Dermatol ; Safavi K.

Some people with alopecia areata may choose accessories, wigs, or cosmetic alternatives to address their hair loss, while others opt not to cover affected areas.
Corticosteroids taken in the form of a pill are sometimes prescribed for extensive scalp hair loss to try to suppress disease activity and regrow hair. Some patients may experience hair regrowth during the short period of time they are able to tolerate using this medication. Healthy, young adults can usually tolerate corticosteroid pills with few side effects. However, doctors do not prescribe corticosteroid pills as often as other treatments for alopecia areata, because of the health risks and side effects associated with using them for a long period of time.
As with other options, hair regrown with corticosteroid use may fall back out once treatment is stopped. Topical immunotherapy is used to treat extensive alopecia areata, alopecia totalis and alopecia universalis. This causes an allergic rash allergic contact dermatitis that looks like poison oak or ivy, which alters the immune response.
Patients who successfully regrow scalp hair usually must continue treatment in order to maintain the regrowth. Side effects — redness, itching and a rash at the site of application — are common. The National Alopecia Areata Foundation can help you find a specialist who offers this treatment in the U.
Immunomodulatory drugs — specifically, Janus kinase JAK inhibitors — such as tofacitinib Xeljanz and ruxolitinib Jakafi , are a new type of therapy being tested for alopecia areata. These medications were originally approved to treat certain blood disorders and rheumatoid arthritis. They are not approved by the FDA for alopecia areata yet, and are only available right now in the form of an oral medication.
A topical formulation is currently in clinical trials in the United States. This has been observed in the small number of patients studied so far. Patients with alopecia areata, alopecia totalis and alopecia universalis can be treated based on age and severity of the condition. This algorithm outlines an approach that can be used from mild to severe forms of the disorder. There are now choices that the patient can decide on what is best for them based on efficacy, cost and side effect profile.
