| Abstract|| |
Context: Alopecia areata (AA), an autoimmune disorder, can affect any hair-bearing area. No treatment so far has produced a consistent response. Narrow band ultraviolet B (NBUVB) has not been studied in its management. Aims: Comparative evaluation of intralesional triamcinolone acetonide injection, NBUVB, and their combination in AA. Materials and Methods: Forty patients (28 males and 12 females) with at least three patches of hair loss were enrolled after obtaining written informed consent. Patches were subdivided as follows: Patch 1 was injected with triamcinolone acetonide 2.5 mg/ml (total of three injections) at 3 weeks interval. Patch 2 - NBUVB was given twice a week for a total of 12 weeks. Patch 3 - combination of injection and NBUVB. Therapeutic response was recorded as regrowth of terminal hair (G0 to G4). Statistical Analysis Used: Chi-square test. P < 5% was considered significant. Results: At the end of treatment and follow-up, that is, at week 12, more than 50% of hair regrowth was evident in 27 (67.5%) patients with intralesional steroid; 7 (17.5%) with NBUVB; and 25 (62.5%) patients with their combination. This difference in the clinical response was statistically significant. Conclusions: Intralesional steroid is more effective than NBUVB and their combination is not synergistic in terms of the clinical response in AA.

| Introduction|| |
Hair is extremely important cosmetically, emotionally, and psychologically. Alopecia areata (AA) is a recurrent, chronic, autoimmune, nonscarring type of hair loss that can affect any hair-bearing area occurring in genetically predisposed individuals. Intralesional corticosteroids are extensively used in the management of AA.  They are considered the first-line treatment in localized alopecia involving <50% of the scalp. However, intralesional steroid injections are associated with a variety of side effects and are also painful. As a result, the search for alternatives to steroids has been felt as the need of the hour. Impressed by the results of psoralen photochemotherapy in AA, we thought of trying narrow band ultraviolet B (NBUVB) in AA. An extensive review of the literature, however, revealed only one study done by Bayramgürler et al. in 2011. In this study, 8/25 (32%) patients received monthly intramuscular corticosteroid injections. Four (22.2%) patients in extensive patchy hair loss group and 2 (20%) patients in entire scalp hair loss group achieved an excellent response. Four of these six patients who achieved excellent response also received monthly intramuscular corticosteroid injections. NBUVB was found to have excellent treatment responses in 20% patients with severe AA, most of whom were also treated with systemic corticosteroids.  However, this study did not distinguish as to what was the cause of therapeutic effect: Steroids or NBUVB. Hence, this study was undertaken to do a comparative evaluation of intralesional triamcinolone acetonide injection, NBUVB, as well as their combination.
| Aims and objectives|| |
- To evaluate the therapeutic efficacy of intralesional triamcinolone acetonide injection 2.5 mg/ml in AA
- To assess the therapeutic efficacy of NBUVB in AA
- To assess the therapeutic efficacy of combined intralesional triamcinolone acetonide injection 2.5 mg/ml and NBUVB in AA
- Comparative evaluation of intralesional triamcinolone acetonide injection 2.5 mg/ml, NBUVB, and their combination in AA.

Department of Dermatology, Venereology, and Leprology, G. G. S. Medical College and Hospital, Faridkot.
A total of 40 patients of AA with at least three patches were enrolled from Outpatient Department of Dermatology, Venereology, and Leprology at G. G. S. Medical College and Hospital, Faridkot.
The diagnosis was based upon the clinical examination, hair microscopy for exclamation mark hair, and potassium hydroxide examination to rule out fungal infection.
- Patients having a minimum of three patches of AA
- Patients of both genders between the ages of 15-50 years.
A written informed consent was taken from each patient before starting the study. A detailed history and general physical examination and local examination were conducted in each case and were recorded on a prescribed proforma.
- Children aged <15 years
- Patients with cicatricial alopecia
- Patients with alopecia universalis
- Patients with history of photosensitivity
- Patients with lupus erythematosus
- Patients with past or present history of skin cancer
- Patients taking photosensitizing/phototoxic drugs.
Each patient was subjected to the following investigations at the time of reporting:
- Total leucocyte count, differential leucocyte count
- Peripheral blood film
- Fasting blood sugar
- Renal function tests
- Liver function tests
- Total and differential serum proteins
- Serum electrolytes and serum calcium
- Hair microscopy for exclamation mark hairs
- Potassium hydroxide mounts to rule out fungal infection
- Thyroid stimulating hormone, T3, T4
- Anti-nuclear antibody
- Venereal Disease Research Laboratory
- Human immunodeficiency virus enzyme-linked immunosorbent assay.
- NBUVB chamber
- UV blocking goggles
- Black gown and sheets to protect the nondiseased parts of body
- Injection triamcinolone acetonide 2.5 mg/ml
- Insulin syringe
- Sterile normal saline for a dilution of steroid injection.
Patches of AA were subdivided as follows:
Schedule of treatment
- Patch 1: Patch was injected with triamcinolone acetonide 2.5 mg/ml. Normal saline was used to dilute triamcinolone acetonide which is commercially available as 10 mg/ml. After cleaning the area with povidone iodine solution, insulin syringe was used to give multiple injections of 0.1 ml each, approximately 1 cm apart. The solution was injected in or just beneath the dermis and a maximum of 3 ml in one visit were used
- Patch 2: Patch was exposed to NBUVB with initial dose of 300 mJ/cm 2 with increments of 10% at every visit, till minimal erythema developed
- Patch 3: Patch was first injected with triamcinolone acetonide as described above followed by exposure to NBUVB with dose as mentioned above.
All the selected patches were assessed clinically as well as photographically at the baseline, at each visit, and at each follow-up visit.
- Patch 1: Injection triamcinolone acetonide 2.5 mg/ml was given at day 0, week 3, and week 6. After that, follow-ups were done fortnightly for the next 6 weeks, completing a total period of 12 weeks
- Patch 2: NBUVB exposure was done twice a week from day 0 to week 6. After that, follow-ups were done fortnightly for next 6 weeks, completing a total period of 12 weeks. During follow-ups, NBUVB exposures were continued if no hair regrowth was observed
- Patch 3: Day 0 - injection triamcinolone acetonide 2.5 mg/ml was given into the patch followed by exposure to NBUVB twice weekly. At week 3 - injection triamcinolone acetonide was given into the patch followed by continued NBUVB exposure twice weekly. At week 6 - injection triamcinolone acetonide 2.5 mg/ml was given. After that, follow-ups were done fortnightly, completing a total period of 12 weeks.
Patient's response to the treatment was graded as follows:
Results were analyzed photographically as well as statistically (using Chi-square test) after a follow-up period of 12 weeks.
- G0 no growth
- G1 <25% regrowth (poor)
- G2 <50% regrowth (fair)
- G3 <75% regrowth (good)
- G4 complete regrowth (excellent).
| Results and observations|| |
The maximum number of 14 patients was in the age group of 20-29 years and the minimum number of four subjects was in 40-49 years age group which shows decreasing incidence with age [Table 1]. Males outnumbered the females in this study [Table 2].
Patients from the urban area were more than the rural ones [Table 3]. The maximum number of patients was farmers (35%) and the minimum was those in government service (5%) [Table 4]. The most common site affected was the scalp (67.5%) [Table 5]. Most of the patients had <1 year of history [Table 6]. The family history of AA was positive in one patient [Table 7]. Sixty five percentage of the patients had three lesions while the rest of the cases had 4-8 patches [Table 8]. Nail changes were seen in 42.5% of cases in this study [Table 9].
Clinical response in terms of hair regrowth and re-pigmentation of hair is depicted in [Table 10] [Table 11] [Table 12] [Table 13] [Table 14] [Table 15] and [Graphs 1] [Graph 2] [Graph 3] [Graph 4] [Graph 5] [Graph 6].
| Discussion|| |
AA was previously known as pelade or area celsi. The disease was first described by Cornelius Celsus in 30 AD. The term AA was first used by Sauvages in 1760.
Age distribution of alopecia areata
In this study of 40 patients with age ranging from 15 to 50 years, majority of patients was in the age group of 20-29 years (35%), closely followed by 12 (30%) in the age group of 30-39 years, and 10 (25%) aged 10-19 years. Thus, a total of 90% occurred below the age of 40 years. This observation was similar to another study which states that 85.5% of the Asian patients with AA have disease onset before 40 years of age. 
Sex wise distribution of alopecia areata
In the present study comprising of 40 patients, there were 28 (70%) males and 12 (30%) females. Some studies show a significant male preponderance in the adult age group, although others identify contrasting results. ,
Patients from urban areas outnumbered the rural ones in this study. Of 40 cases, 25 (62.5%) were from urban area while 15 (37.5%) were rural.
Of 40 subjects, 14 (35%) were farmers followed in decreasing frequency by students 13 (32.5%), housewives 7 (17.5%), shopkeepers 4 (10%), and the least common were those in government service 2 (5%).
Site of involvement in alopecia areata
The most common site affected was scalp in 27 (67.5%) while beard was involved in 24 (60%) cases. The least affected site was eyebrows in only 2 (5%) patients.
Duration of the disease ranged from 1 month to 8 years. Maximum number of the patients, that is, 26 (65%) had <1 year of history, 11 (27.5%) had duration between 1 and 5 years, and 3 (7.5%) had more than 5 years of the problem of hair loss.
Past history of alopecia areata
Of 40 patients, 12 (30%) had a past history of AA. Eight patients had a single episode, two had two episodes, and 1 patient each had three and multiple episodes, respectively.
One (2.5%) out of 40 patients had a positive family history of the disease in this study which differs from other studies having a significant family history.
Various other studies show that family incidence of AA varies from 10 to 20%. 
Number of lesions of alopecia areata
The majority of patients 26 (65%) had three lesions, 4 (10%) had four lesions while the remaining had five or more lesions. Small patches closely arranged in the reticulate pattern have been found to carry a poorer prognosis. 
Nail changes were evident in 17 (42.5%) of the total 40 patients in the form of leukonychia, pitting, longitudinal striations, longitudinal ridging, and beau's lines.
Gandhi et al. observed pitting to be the most common nail finding in patients with alopecia areata, but leukonychia was the most frequent nail change in this study. 
Response to treatment
At week 4, 5 (12.5%) achieved Grade 3 response and 4 (10%) had Grade 2 hair regrowth among P1 group. In P2 treated with NBUVB, only 1 (2.5%) could show Grade 2 response. In P3, 6 (15%) showed Grade 2 hair regrowth.
At week 8, more than 50% hair growth was seen in 13 (32.5%) in P1, 5 (12.5%) in P2, and 11 (27.5%) in P3. Again the response was statistically significant.
At the end of treatment and follow-up, that is, at week 12, more than 50% response was evident in 27 (67.5%) with 14 (35%) showing Grade 4 regrowth in P1 group. Among P2 patches treated with NBUVB, only 7 (17.5%) showed >50% response with 5 (12.5%) having Grade 4 hair regrowth. In P3, 25 (62.5%) had >50% hair gain with 13 (32.5%) showing Grade 4 response.
At week 4, 23 (57.5%) in P1, 5 (12.5%) in P2, and 23 (57.5%) in P3 showed growth of pigmented hair. De-pigmented hair were seen in 3 (7.5%) in P1, 3 (7.5%) in P2, and 6 (15%) in P3. This difference in the clinical response was statistically significant (P = 0.000).
Assessment at week 8 revealed 34 (85%) in P1 showing pigmented hair while corresponding values for P2 and P3 were 23 (57.5%) and 32 (80%), respectively (P = 0.050).
At week 10, the response in the form of pigmentation of hair among the three groups became insignificant (P = 0.331) with 34 (85%) in P1, 28 (70%) in P2, and 32 (80%) in P3 showing growth of pigmented hair. These effects were maintained at week 12 as well. The follow-ups of patients are depicted in [Figure 1] and [Figure 2].

Review of literature regarding the use of NBUVB in AA revealed only one retrospective study done by Bayramgürler et al. which showed an excellent response in 20% of patients, most of whom were also treated with systemic corticosteroids. Hence, this study did not answer as to whether steroids or NBUVB led to clinical response. 
In this study, good clinical response to NBUVB in the form of more than 50% hair regrowth was seen in only 17.5% of cases which is lower than the treatment effect seen in the study done by Bayramgürler et al. This could be attributed to the concurrent use of systemic corticosteroids in the study done by Bayramgüürler et al.
Good hair growth was evident in 67.5% of patients treated with a total of three intralesional steroid injections given at 3 weekly intervals in this study which was close to what was observed by Abell and Munro. 
The side effects associated with NBUVB were minimal with minority of patients complaining of transient itching or redness in the treated area. Otherwise, it was well tolerated. However, intralesional triamcinolone acetonide injection was associated with significant side effects such as pain, minor bleeding, folliculitis, and transient atrophy.
| Conclusions|| |
To conclude, intralesional steroids were more effective than NBUVB and their combination was not synergistic in terms of the clinical response. There was no statistical difference in terms of pigmented hair regrowth in either of the treatment modalities. Minimal to no side effects were reported with NBUVB while intralesional steroid injection was associated with side effects such as pain, minor bleeding, folliculitis, and transient atrophy.
