Abstract
Alopecia areata (AA) is a kind of alopecia that affects hair follicles and nails. It typically comes with round patches and is a type of nonscarring hair loss. Various therapies are accessible for the management and treatment of AA, including topical, systemic and injectable modalities. It is a very complex type of autoimmune disease and is identified as round patches of hair loss and may occur at any age. This review paper highlights the epidemiology, clinical features, pathogenesis and new treatment options for AA, with a specific emphasis on nanoparticulate drug-delivery systems. By exploring these innovative treatment approaches, researchers aim to enhance the effectiveness and targeted delivery of therapeutic agents, ultimately improving outcomes for individuals living with AA.

Abstract
Treatments for alopecia areata (AA) have traditionally been prescribed off-label, and there has been no universal agreement on how to best manage the condition. Baricitinib is the first oral selective Janus kinase (JAK) inhibitor approved for the treatment of adults with severe AA. As a better understanding of the evidence supporting the management of AA in clinical practice is needed, we conducted a systematic literature review and subsequent narrative review to describe available evidence pertaining to the efficacy and tolerability of treatments currently recommended for adults with moderate-to-severe forms of AA. From 2557 identified records, a total of 53 records were retained for data extraction: 9 reported data from 7 randomized controlled trials (RCTs) versus placebo, and 44 reported data from unique RCTs with no placebo arm, non-randomized trials, or observational studies. Across drug classes, data were reported heterogeneously, with little consistency of data collection or clinical endpoints used. The most robust evidence was for the JAK inhibitor class, in particular the JAK1/JAK2 inhibitor baricitinib. Five RCTs (three for baricitinib) demonstrated a consistent benefit of JAK inhibitor therapy over placebo across various clinical outcomes in adult patients with at least 50% scalp hair loss. Overall, hair regrowth varied widely for the other drug classes and was generally low for patients with moderate-to-severe AA. Relapses were commonly observed during treatment and upon discontinuation. Adverse effects were generally consistent with the known safety profile of each intervention. The heterogeneity observed prevented the conduct of a network meta-analysis or an indirect comparison of different treatments. We found that the current management of patients with moderate-to-severe AA often relies on the use of treatments that have not been well evaluated in clinical trials. The most robust evidence identified supported the use of baricitinib, and other oral JAK inhibitors, in patients with severe AA.

Abstract
BACKGROUND Alopecia areata (AA) is a common disease characterized by hair loss with an autoimmune background. There are many lines of therapy, but no standard line for all cases. Consequently, treating severe forms of AA is challenging. OBJECTIVE This study aimed to compare the efficacy and safety of the combination of diphenylcyclopropenone (DPCP) and platelet-rich plasma (PRP) with DPCP alone in treating patients with severe or refractory AA. PATIENTS AND METHODS Our randomized clinical trial was conducted on patients with severe and recalcitrant AA. Group A included 13 patients who received only DPCP, while Group B included 11 patients who received both DPCP and PRP. After sensitization in both groups of patients, DPCP was applied to half the scalp weekly. In addition, PRP injection in all scalp was performed once a month in group B. The patients in both groups completed the study for six months. RESULTS The regrowth scale results were 53.85% and 54.5% for groups A and B, respectively. Although the response rate of group B was higher than that of group A, there is no statistically significant difference between the two groups. CONCLUSION From our clinical trial, it can be concluded that DPCP alone or combined with PRP is an effective and safe method for treating severe or recalcitrant AA.

Abstract
BACKGROUND Alopecia areata is an autoimmune disease leading to nonscarring hair loss on the scalp or body. There are different treatments including immunosuppressants, hair growth stimulants, and contact immunotherapy. OBJECTIVES To assess the benefits and harms of the treatments for alopecia areata (AA), alopecia totalis (AT), and alopecia universalis (AU) in children and adults. SEARCH METHODS The Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, ClinicalTrials.gov and WHO ICTRP were searched up to July 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) that evaluated classical immunosuppressants, biologics, small molecule inhibitors, contact immunotherapy, hair growth stimulants, and other therapies in paediatric and adult populations with AA. DATA COLLECTION AND ANALYSIS We used the standard procedures expected by Cochrane including assessment of risks of bias using RoB2 and the certainty of the evidence using GRADE. The primary outcomes were short-term hair regrowth ≥ 75% (between 12 and 26 weeks of follow-up), and incidence of serious adverse events. The secondary outcomes were long-term hair regrowth ≥ 75% (greater than 26 weeks of follow-up) and health-related quality of life. We could not perform a network meta-analysis as very few trials compared the same treatments. We presented direct comparisons and made a narrative description of the findings. MAIN RESULTS We included 63 studies that tested 47 different treatments in 4817 randomised participants. All trials used a parallel-group design except one that used a cross-over design. The mean sample size was 78 participants. All trials recruited outpatients from dermatology clinics. Participants were between 2 and 74 years old. The trials included patients with AA (n = 25), AT (n = 1), AU (n = 1), mixed cases (n = 31), and unclear types of alopecia (n = 4). Thirty-three out of 63 studies (52.3%) reported the proportion of participants achieving short-term hair regrowth ≥ 75% (between 12 and 26 weeks). Forty-seven studies (74.6%) reported serious adverse events and only one study (1.5%) reported health-related quality of life. Five studies (7.9%) reported the proportion of participants with long-term hair regrowth ≥ 75% (greater than 26 weeks). Amongst the variety of interventions found, we prioritised some groups of interventions for their relevance to clinical practice: systemic therapies (classical immunosuppressants, biologics, and small molecule inhibitors), and local therapies (intralesional corticosteroids, topical small molecule inhibitors, contact immunotherapy, hair growth stimulants and cryotherapy). Considering only the prioritised interventions, 14 studies from 12 comparisons reported short-term hair regrowth ≥ 75% and 22 studies from 10 comparisons reported serious adverse events (18 reported zero events and 4 reported at least one). One study (1 comparison) reported quality of life, and two studies (1 comparison) reported long-term hair regrowth ≥ 75%. For the main outcome of short-term hair regrowth ≥ 75%, the evidence is very uncertain about the effect of oral prednisolone or cyclosporine versus placebo (RR 4.68, 95% CI 0.57 to 38.27; 79 participants; 2 studies; very low-certainty evidence), intralesional betamethasone or triamcinolone versus placebo (RR 13.84, 95% CI 0.87 to 219.76; 231 participants; 1 study; very low-certainty evidence), oral ruxolitinib versus oral tofacitinib (RR 1.08, 95% CI 0.77 to 1.52; 80 participants; 1 study; very low-certainty evidence), diphencyprone or squaric acid dibutil ester versus placebo (RR 1.16, 95% CI 0.79 to 1.71; 99 participants; 1 study; very-low-certainty evidence), diphencyprone or squaric acid dibutyl ester versus topical minoxidil (RR 1.16, 95% CI 0.79 to 1.71; 99 participants; 1 study; very low-certainty evidence), diphencyprone plus topical minoxidil versus diphencyprone (RR 0.67, 95% CI 0.13 to 3.44; 30 participants; 1 study; very low-certainty evidence), topical minoxidil 1% and 2% versus placebo (RR 2.31, 95% CI 1.34 to 3.96; 202 participants; 2 studies; very low-certainty evidence) and cryotherapy versus fractional CO2 laser (RR 0.31, 95% CI 0.11 to 0.86; 80 participants; 1 study; very low-certainty evidence). The evidence suggests oral betamethasone may increase short-term hair regrowth ≥ 75% compared to prednisolone or azathioprine (RR 1.67, 95% CI 0.96 to 2.88; 80 participants; 2 studies; low-certainty evidence). There may be little to no difference between subcutaneous dupilumab and placebo in short-term hair regrowth ≥ 75% (RR 3.59, 95% CI 0.19 to 66.22; 60 participants; 1 study; low-certainty evidence) as well as between topical ruxolitinib and placebo (RR 5.00, 95% CI 0.25 to 100.89; 78 participants; 1 study; low-certainty evidence). However, baricitinib results in an increase in short-term hair regrowth ≥ 75% when compared to placebo (RR 7.54, 95% CI 3.90 to 14.58; 1200 participants; 2 studies; high-certainty evidence). For the incidence of serious adverse events, the evidence is very uncertain about the effect of topical ruxolitinib versus placebo (RR 0.33, 95% CI 0.01 to 7.94; 78 participants; 1 study; very low-certainty evidence). Baricitinib and apremilast may result in little to no difference in the incidence of serious adverse events versus placebo (RR 1.47, 95% CI 0.60 to 3.60; 1224 participants; 3 studies; low-certainty evidence). The same result is observed for subcutaneous dupilumab compared to placebo (RR 1.54, 95% CI 0.07 to 36.11; 60 participants; 1 study; low-certainty evidence). For health-related quality of life, the evidence is very uncertain about the effect of oral cyclosporine compared to placebo (MD 0.01, 95% CI -0.04 to 0.07; very low-certainty evidence). Baricitinib results in an increase in long-term hair regrowth ≥ 75% compared to placebo (RR 8.49, 95% CI 4.70 to 15.34; 1200 participants; 2 studies; high-certainty evidence). Regarding the risk of bias, the most relevant issues were the lack of details about randomisation and allocation concealment, the limited efforts to keep patients and assessors unaware of the assigned intervention, and losses to follow-up. AUTHORS' CONCLUSIONS We found that treatment with baricitinib results in an increase in short- and long-term hair regrowth compared to placebo. Although we found inconclusive results for the risk of serious adverse effects with baricitinib, the reported small incidence of serious adverse events in the baricitinib arm should be balanced with the expected benefits. We also found that the impact of other treatments on hair regrowth is very uncertain. Evidence for health-related quality of life is still scant.

Abstract
BACKGROUND Alopecia areata (AA) is a chronic disease with an unpredictable disease course and severe psychological impact. OBJECTIVE To provide evidence- and consensus-based insights regarding the treatment of patients with AA in Korea. METHODS We searched for relevant studies on the topical and device-based treatment of AA in the literature from inception until May 2021. Evidence-based recommendations were also prepared. The evidence for each statement was graded and classified according to the strength of the recommendations. Hair experts from the Korean Hair Research Society (KHRS) voted on the statements, and an agreement of 75% or greater was considered as consensus. RESULTS Currently, there remains a scarcity of topical treatments, which is supported by robust evidence from a number of high-quality randomized controlled trials. Current evidence supports the efficacy of topical corticosteroids, corticosteroid intralesional injection, and contact immunotherapy in AA patients. Topical corticosteroids and contact immunotherapy are recommended for pediatric AA. A consensus was achieved in 6 out of 14 (42.8%), and 1 out of 5 (20.0%) statements pertaining to topical and device-based treatments in AA, respectively. The expert consensus was from a single country, and the study may not cover all the treatments used. CONCLUSION The present study provides up-to-date, evidence-based treatment guidelines for AA based on the consensus reached among experts after considering regional healthcare circumstances, adding diversity to the previous guidelines.

Abstract
BACKGROUND Alopecia areata (AA) is a chronic disorder and the best treatment regimen for it is unknown. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. AIM To evaluate the safety and efficacy of a novel method (multi-concentration patch test) versus standard protocol for topical immunotherapy. METHODS A prospective randomized clinical trial was conducted on 30 patients with Alopecia areata, half of them received DPCP with a novel method using multi-concentration patch test to determine the optimal initiating concentration of DPCP (case group) and the other half experienced immunotherapy according to the standard protocol (control group). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. (IRCT registration code: IRCT20141209020250N5). RESULTS Absolute and relative hair regrowth percentages were reported 25% and 41.49% in case group and 8.2% and 14.21% in control group respectively. Considerable response (more than 75% hair regrowth) was observed in 4 (26.6%) patients in case and 1 (6.6%) patient in control group. The clinical response was initiated about 7 weeks sooner in case compared to the control group (14 versus 7.38 weeks, P: 0.001). Overall, clinical response was higher in patients received new protocol, compared to control group. Moreover, patients who experienced new protocol had a higher level of treatment satisfaction in comparison with patients having standard protocol (P: 0.012). CONCLUSION This study revealed the effectiveness and safety of the novel multi-concentration patch test DPCP therapy for AA and its priority to conventional method, at least in terms of shortened duration of DPCP immunotherapy.

Abstract
BACKGROUND Alopecia areata (AA) is a chronic autoimmune disorder. Finding the best treatment regimen for it remains a challenge. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. AIM To evaluate the safety and efficacy of combined DPCP and anthralin versus standard protocol (DPCP alone). METHODS A prospective randomized clinical trial was conducted on 50 patients with Alopecia areata who received DPCP alone (group D) or in combination with anthralin (group D/A). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. RESULTS Complete hair regrowth was observed among three patients in each group (18.75% in Group D and 15.79% in Group D/A) after 6 months. Moreover, 25% and 31% of patients in group D and 21% and 47% of patients in group D/A had > 75% and > 50% hair regrowth respectively at the end of the study (P-value: 0.696). In addition, earlier age of onset, chronicity of lesions, nail involvement, facial hair loss and extensive lesions at baseline were associated with poor clinical outcome. CONCLUSION DPCP and anthralin was as effective as DPCP alone and anthralin did not add to the effect of DPCP in treating AA.

Abstract
Treatment of extensive or recalcitrant alopecia areata (AA) is a major clinical challenge. Even after thorough investigation of several medications, its treatment outcomes have remained unsatisfactory. While there is no US Food and Drug Administration-approved medication for AA yet, topical immunotherapy has been a well-documented treatment option. Dinitrochlorobenzene, squaric acid dibutylester, and diphenylcyclopropenone are three substances that have demonstrated efficacy in the treatment of extensive or recalcitrant AA. Despite being commonly used, the mechanism underlying topical immunotherapy is not well-elucidated and a wide range of clinical efficacies have been reported in the literature. The aim of this review was to summarize and update the pharmacology, mechanism of action, therapeutic efficacy, and tolerability of topical immunotherapy in the treatment of AA.

[PMID: 33325128 DOI: 10.1111/exd.14254] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 11/19/2020] [Accepted: 12/03/2020] [Indexed: 12/19/2022]
Abstract
Topical immunotherapy with diphenylcyclopropenone (DPCP) is considered to be the most effective treatment of severe AA. However, the mechanism is unclear and an early predictor for the efficacy needs to be explored. The TSLP/OX40L/IL-13 pathway is an important pathway to initiate and maintain Th2 immune responses. Our previous work suggests this pathway may play a role in severe AA treated with DPCP. Thus, to further investigate the mechanism of TSLP/OX40L/IL-13 pathway in severe AA treated with DPCP and explore the predictor for the efficacy of DPCP therapy, we conducted a prospective study to compare expression levels of TSLP, OX40L, Th2 cytokines IL-4, IL-5 and IL13, and Th1 cytokine IFN-γ in severe AA patients before and after the treatment. Results showed that 21 AA patients were responsive (responders) to the DPCP therapy and 12 were not responsive (non-responders). Responders had lower levels of TSLP, OX40L and IL-13 than non-responders before the treatment. After the DPCP treatment, TSLP, IL-5 and IL-13 increased and IFN-γ decreased in responders while there were no changes of TSLP, IL-4, IL-13 and IFN-γ in non-responders. Our data suggest that the TSLP/OX40L/IL-13 pathway is down-regulated in some severe AA patients and DPCP might play a therapeutic role by up-regulating the pathway in these severe AA patients. The TSLP/OX40L/IL-13 pathway could be a predictor of response to the DPCP therapy for severe AA patients.

Abstract
BACKGROUND Treatment is often challenging in patients with alopecia areata. We often try topical immunotherapy to treat alopecia areata in Japan. Anthralin is sometimes used in other countries. OBJECTIVES The aim of this study was to examine effectiveness of combination therapy with both topical immunotherapy with squaric acid dibutylester or diphenylcyclopropenone and anthralin in the treatment of refractory alopecia areata. METHODS We treat four patients with refractory alopecia areata by topical immunotherapy and anthralin. Two patients had alopecia areata multilocularis and the other two patients had alopecia totalis. The entire scalp was treated with weekly application of squaric acid dibutylester or diphenylcyclopropenone and daily 0.5% anthralin ointment. Patients were followed up weekly, and adverse effects were recorded. RESULTS One patient with multifocal patches of alopecia areata got complete hair regrowth at week 30, the other patient with multifocal patches of alopecia areata turned for the worse at week 30 and recovered at week 52. Hair regrowth was not seen in the other two patients with alopecia totalis. Localized pruritis and hyperpigmentation of the scalp were seen in two patients. CONCLUSIONS To treat alopecia areata unresponsive to topical immunotherapy alone, topical immunotherapy in combination with anthralin is worth a try.

Abstract
Diphenylcyclopropenone (DPCP) is an effective topical immunotherapy for recalcitrant alopecia areata (AA), which sometimes requires prolonged treatment. We developed a new treatment protocol to shorten the duration of therapy. This study aimed to compare the efficacy and safety of the new treatment protocol with the standard treatment protocol in the treatment of recalcitrant AA. We conducted a 6-year retrospective comparative study of patients with AA who received one of the DPCP treatment protocols at our institute. Patients’ information was collected and subsequent statistically analyzed. Thirtynine patients (16 in the new treatment group and 23 in the standard treatment group) were included. There were no statistically significant differences in area of hair regrowth. Mean duration to initial hair regrowth and mean duration to significant hair regrowth in the new treatment group were significantly shorter than in the standard treatment group (P=0.002 and 0.01, respectively). Adverse effects were slightly higher in the new treatment group. The present study reveals the effectiveness and safety of the new treatment protocol, which shortens the duration of DPCP treatment and could represent an alternative regimen.

Abstract
Diphenylcyclopropenone (DPCP) is widely considered the most effective topical immunotherapy for refractory or extensive alopecia areata (AA), but questions regarding how long to try DPCP therapy before terminating and what factors are prognostic of therapeutic success still remain unanswered. In this retrospective study of 50 AA patients, we evaluated DPCP efficacy and identified patient factors predictive of therapeutic success/failure. The median duration of DPCP treatment was 3 years, with 47% patients experiencing their first regrowth in the first 6 months of DPCP therapy, 20% between 6 months-1 year, and 8% between 1-2 years. In our study, treatment success, defined as ⩾50% terminal hair regrowth, was reached in 71% of alopecia totalis patients and in 56% of alopecia universalis patients. Three factors were statistically significant predictors of poor treatment outcome-extent of hair loss before DPCP treatment, history of thyroid disease, and extent of body hair involvement. Relapse was observed in 44% of patients and significantly associated with history of thyroid disease. Common side effects were itching, rash, and local lymphadenopathy. The results of this study support our belief that DPCP therapy is a viable treatment option, can be successfully accomplished at home, and should not be terminated before 2 years.

Abstract
Diphencyprone (DPCP) is a potent topical sensitizing agent that has been used since the late 1970s by physicians for the treatment of alopecia areata (AA), viral warts (human papillomavirus) and cutaneous metastases of melanoma. Although to date the compound is not approved as a drug by the FDA or EMA, physicians have continued to use DPCP because of its proven effects in these dermatological conditions. The use of the drug has been highly variable because of differences in compounding, and as a result, the literature reports vary widely in the concentrations used for sensitization and challenge treatment with DPCP. The efficacy of DPCP has generally been ascribed to immunological reactions by the host. Inducing inflammation with a contact sensitizer is counterintuitive to treating AA, an autoimmune disorder. We have hypothesized that the body's attempt to downregulate the inflammation caused by the contact sensitizer may also ameliorate AA. Studies using microarray and miRNA profiling may provide information about how DPCP induces inflammation in human skin at different times. Gene targets and microRNAs identified through these data may be modulated by an RNA interference approach to enhance DPCP efficacy and response rates. In addition, this approach may result in the discovery and development of drugs that are more potent and selective for the treatment of AA.

Abstract
Delivery of diphencyprone (DPCP) and minoxidil to hair follicles and related cells is important in the treatment of alopecia. Here we report the development of "squarticles," nanoparticles formed from sebum-derived lipids such as squalene and fatty esters, for use in achieving targeted drug delivery to the follicles. Two different nanosystems, nanostructured lipid carriers (NLC) and nanoemulsions (NE), were prepared. The physicochemical properties of squarticles, including size, zeta potential, drug encapsulation efficiency, and drug release, were examined. Squarticles were compared to a free control solution with respect to skin absorption, follicular accumulation, and dermal papilla cell targeting. The particle size of the NLC type was 177 nm; that of the NE type was 194 nm. Approximately 80% of DPCP and 60% of minoxidil were entrapped into squarticles. An improved drug deposition in the skin was observed in the in vitro absorption test. Compared to the free control, the squarticles reduced minoxidil penetration through the skin. This may indicate a minimized absorption into systemic circulation. Follicular uptake by squarticles was 2- and 7-fold higher for DPCP and minoxidil respectively compared to the free control. Fluorescence and confocal images of the skin confirmed a great accumulation of squarticles in the follicles and the deeper skin strata. Vascular endothelial growth factor expression in dermal papilla cells was significantly upregulated after the loading of minoxidil into the squarticles. In vitro papilla cell viability and in vivo skin irritancy tests in nude mice suggested a good tolerability of squarticles to skin. Squarticles provide a promising nanocarrier for topical delivery of DPCP and minoxidil.

Abstract
Diphencyprone (DCP) is a contact sensitizer which is used to treat dermatological disorders with an immunological origin, such as extensive alopecia areata (AA). Vitiligo is a rare but known side effect of DPCP therapy which is formed in the treatment site or remote areas. In this paper a 37-year-old man developed alopecia totalis with loss of eyebrows and eyelashes who presented some vitiligo patches on his scalp and arm distant from the location of DPCP application and a 42-year-old woman with 25 years history of hair loss and 3 months DPCP application who revealed some vitiligo patches on the scalp with distant to the site of application at the 6th week are reported. Considering the absence of personal and family history of Vitiligo in our two cases, the hypothesis of latent Vitiligo is not proved. The positive patch test in left arm of one of the patients also suggests the direct role of DPCP as the cause of Vitiligo occurrence. As the development of vitiligo by DCP is unpredictable and the depigmentation may persist indefinitely, it is important to inform all patients about this potential adverse effect before starting the treatment.

Abstract
Alopecia Areata (AA) is a common non-scarring alopecia directed against the anagenic hair follicle. Various treatment modalities have been used for the treatment of severe AA. Topical immunotherapy is the best documented treatment so far for severe and refractory AA. Dinitrochlorobenzene (DNCB), squaric acid dibutylester (SADBE), and diphencyprone (DPCP) are the contact allergens used for this purpose. DNCB has been found to be mutagenic by the Ames test and is largely replaced by DPCP and SADBE. DPCP and SADBE are both known to be non-mutagenic compounds and have comparable efficacy results and relapse rates. SADBE requires special solvents and additives to maintain its potency and is more expensive than the rest. DPCP has a response rate varying from 60% in severe Alopecia Areata to 17% in patients with alopecia totalis or universalis, and shows about 88 to 100% high response rate in patients with patchy Alopecia Areata.

Abstract
BACKGROUND Although diphenylcyclopropenone (DCP) is frequently used for the treatment of alopecia areata (AA), large studies with more than 100 patients are still scarce. OBJECTIVE To determine the efficacy of DCP immunotherapy in a large cohort of patients with AA who had been treated in our institute from January 2000 to December 2006. METHODS A total of 142 patients with AA undergoing topical DCP therapy in a self-controlled design were evaluated retrospectively. RESULTS Seven patients (4.9%) were anergic to DCP. Two of 135 patients (1.5%) discontinued DCP therapy because of adverse effects. Fifty-one patients (37.8%) had a complete response (CR: >90% re-growth of hair), 20 patients (14.8%) exhibited a partial response (PR: >50-90% re-growth), 26 patients (19.3%) experienced a minimal response (MR: 10-50% re-growth) and 38 patients (28.1%) had no response after DCP therapy (NR: <10% re-growth). Bivariate logistic analysis revealed that severity of hair loss at the beginning of DCP (P=0.001) is the only significant prognostic factor for therapeutic outcome. Twenty-three patients (45.1%) with CR had relapses upon discontinuation of the treatment or even during prolonged DCP therapy. CONCLUSION Topical immunotherapy with DCP of patients with AA is rather effective and mostly well tolerated. The extent of hair loss before therapy is the main predictor for the therapeutic success of DCP. However, DCP therapy is associated with a high degree of relapse of which patients should be well informed.

The aim of our study was to assess the long-term safety and efficacy of MTX in patients with chronic severe forms of AA totalis. PATIENTS AND METHODS Thirty-three patients (24 women and nine men) with AA totalis or universalis were included. Mean disease duration was 7.7 years and these patients had not responded to prior standard treatment. The initial weekly dosage of MTX was 15 mg (n=2), 20mg (n=16) or 25mg (n=15). Nineteen patients (58%) were treated with MTX and low doses of corticosteroids (prednisone 10-20mg/d), while 14 patients (42%) received MTX alone. The primary end-point was complete hair regrowth under treatment. RESULTS Twenty-one patients had total hair regrowth and 13 patients were considered as treatment failures, with 10 of these having partial regrowth and three having no regrowth. Complete regrowth was seen in 12 of 19 patients (63%) on combined treatment and in eight of 14 patients (57%) on MTX alone. The onset of hair regrowth was noted after a median delay of 3 months. At the end of the study, after a median of 30 months' follow-up, the median cumulative dose of MTX was 1.8 g (400mg-5.5 g). Relapse was observed on corticosteroid dose reduction or withdrawal in 16 of the 20 patients in whom total hair regrowth initially occurred. Regrowth after treatment of relapse was seen in 14 of these 16 patients (87%). Seven patients experienced adverse events consisting of transient elevated transaminases (n=4), persistent nausea (n=2) and lymphocytopenia (n=1). CONCLUSION MTX alone or in combination with low doses of oral corticosteroids resulted in complete hair regrowth in about half of these patients presenting AA totalis or universalis. Lasting improvement required continuous treatment in most cases.

Abstract
OBJECTIVE To evaluate the efficacy of two topically applied immunomodulative agents through the detection of lymphocyte subsets using monoclonal antibodies against CD4, CD8 and MHC II. METHODS Fifty patients from the Departments of Medical Biochemistry, Dermatology and Pathology at Cairo University with different degrees of alopecia areata (AA) were included in this study. They were classified into two groups each of 25 patients. Each patient was treated with the immunomodulative agent on one side of the scalp and the other side was left as a control. Biopsies were taken from all patients at the beginning of treatment and at the end of the study. Tissue specimens were prepared for histologic and immunophenotypic analysis. The main outcome measures were the uses of diphencyprone (DPCP) and topical tacrolimus as two topical immunotherapeutic modalities in the treatment of AA. RESULTS A clinical response of 68% was achieved in group A (treated with DPCP) while group B (treated with 0.1% tacrolimus) showed an insignificant clinical response. Decreased expression of CD4 and increased expression of CD8 and MHC II was detected in the post-treated areas compared with pretreated areas in cases treated with DCPC. In tacrolimus-treated cases, there was a decrease in CD4 and MHC II, with no change in CD8 between the pre- and post-treated areas. CONCLUSION DCPC is one of the most accepted therapeutic modalities in the treatment of AA, with a favourable prognosis among patchy hair loss. MHC II expression was the one correlating with clinical response. Tacrolimus, though beneficial in other dermatoses, could not be considered effective in the treatment of AA.
