Comparison of the Clinical Efficacy of Rituximab Infusion and Dexamethasone-Cyclophosphamide Pulse Therapy and Their Effect on Serum Th1, Th2, and Th17 Cytokines in Pemphigus Vulgaris-A Prospective, Nonrandomized, Comparative Pilot Study. Indian Dermatol Online J 2024; 15:464-472. [PMID: 38845632 PMCID: PMC11152478 DOI: 10.4103/idoj.idoj_558_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 09/15/2023] [Accepted: 10/24/2023] [Indexed: 06/09/2024] Open
Abstract
Background Rituximab infusion and dexamethasone-cyclophosphamide pulse (DCP) are the two most popular regimens used in pemphigus vulgaris (PV) in India. Objective The present study compared the clinical efficacy of rituximab and DCP in Indian PV patients and their effects on serum Th1,2, and 17 cytokine levels. Materials and Methods A total of 37 patients received DCP (Group A, n = 22) or rituximab (Group B, rheumatoid arthritis protocol (n = 15)) as per patients' preference. They were monitored for clinical response, adverse events (AEs), changes in serum anti-desmoglein-1,3 antibody titers and Th1,2 and 17 cytokine levels at baseline and weeks 20 and 52. Results The proportion of patients attaining disease control, remission, and relapse in groups A and B were 82% and 93%; 73% and 93%; and 27% and 50%, respectively, after a median duration of 2 months each for disease control; 4 and 4.5 months for remission; and 5 and 7 months for relapse post remission. The musculoskeletal AEs were the highest in the two groups. Significant and comparable decreases in anti-dsg1 and 3 titers from baseline to weeks 20 and 52 were observed in both groups. Th1 and Th17 cytokine levels decreased, while Th2 cytokines increased post-treatment in both groups. However, no correlation was found between change in body surface area of involvement by PV and anti-dsg titers and cytokine levels before and after therapy in both groups. Conclusion Comparable clinical efficacy between DCP and rituximab was observed.

Abstract
Pemphigus vulgaris (PV) is a chronic autoimmune blistering disorder characterized by the loss of intraepithelial adhesion, affecting the skin and mucous membranes. Both males and females are affected, although it predominantly affects females in their fifth and sixth decades of life. Approximately 1.4 to 3.7% of PV cases occur in the pediatric population (≤18 years of age), and may be classified into childhood/pediatric PV, which affects individuals under 12 years old, and juvenile/adolescent PV, affecting those between 12 and 18 years old. Due to its rare occurrence in children and adolescents, there is often a delay in diagnosis and treatment in this age group. A systematic literature search was conducted on MEDLINE/PubMed, Web of Science, EMBASE, SCOPUS, and Cochrane Library databases to evaluate the efficacy of rituximab (RTX) in childhood and juvenile PV patients. The Joanna Briggs Institute (JBI) Critical Appraisal Checklist was employed to assess the risk of bias in case reports and series, while the Cochrane ROBINS-I tool was utilized for evaluating observational studies or non-randomized intervention studies. A total of 18 studies encompassing 46 juvenile or childhood PV patients in the pediatric and adolescent age groups were included for qualitative synthesis. The studies included nine case reports, two case series, five retrospective studies, one prospective study, and one open-label pilot study. Almost all cases of childhood and juvenile PV achieved either complete or partial remission after undergoing RTX treatment during the final follow-up periods. Furthermore, most cases reported no relapse, and only minor adverse events were noted in the RTX treatment group. Despite its potential benefits, the utilization of RTX in pediatric patients raises concerns due to the scarcity of evidence and the absence of controlled studies specific to this age group. Further exploration is necessary to establish a standardized treatment regimen for RTX in pediatric PV, which involves identifying the optimal dosage, frequency, treatment cycle duration, and maintenance therapy duration.

Abstract
Pemphigus is a rare autoimmune blistering condition that used to be fatal before the introduction of corticosteroid (CS) and immunosuppressive agents. Rituximab is a monoclonal anti-CD-20 antibody that induces the pathologic B-cells apoptosis with significant efficacy in the treatment of pemphigus. The application of rituximab can lead to infectious events. We aim to review the reported infectious events in pemphigus patients who previously received rituximab and classify them based on the causative agents. A thorough search of PubMed was conducted using the keywords "rituximab," "pemphigus," "infection," "viral disease," "viral infection," "complication," "efficacy" and their combinations also applying their equivalent Mesh terms and including the references cited in each study. All studies that mentioned at least one infectious event were included. A total of 77 infectious events in 68 patients were reported in the literature out of which the most reported causative agent was viral but the most fatal one found to be bacterial. Although rituximab therapy has shown promising results in controlling pemphigus patients mainly the refractory cases, given possible fatal outcomes, we believe the medical profile of the patients before initiating the therapy warrants careful examination to search for any risk factors or predisposing conditions.

Abstract
BACKGROUND Pemphigus is an autoimmune disease that is challenging to treat and has few available therapeutic options. Recently, several studies have demonstrated that rituximab may be an efficacious first-line treatment in newest guidelines. AIM To compare the side effect profiles of rituximab administered after a course of immunosuppressant agents versus as a first-line therapy and evaluate the impact of patient characteristics and disease severity indices on occurrence of adverse effects. METHODS A retrospective cross-sectional study was conducted on 999 patients with pemphigus vulgaris who received rituximab either as a first-line treatment or after conventional adjuvant therapies. The occurrence of partial or complete remission as well as the incidence of drug-related adverse effects were evaluated and compared between the two groups. RESULTS Smoking, pulmonary comorbidity, and mucocutaneous phenotype were associated with an increased risk of developing infectious complications by 12.49, 5.79, and 2.37 fold, respectively. These associations were more prominent among those who received rituximab after immunosuppressant agents. CONCLUSIONS Early use of rituximab benefits pemphigus patients, especially those with a mucocutaneous phenotype, pulmonary comorbidity, or history of smoking, and reduces their risk of infectious adverse events.

Abstract
In patients who develop sepsis, whether due to primary, secondary or metastatic lesions, the skin is frequently affected. However, there are unresolved aspects regarding the general clinical manifestations in the skin or the prognosis and/or therapeutic implications. The main challenge in the approach to sepsis is its early diagnosis and management. In this review, we address the sepsis-skin relationship and the potential impact of early dermatological intervention on the septic patient through ten basic questions. We found little evidence of the participation of the dermatologist in sepsis alert programs. There are early skin changes that may alert clinicians on a possible sepsis, such as skin mottling or variations in acral skin temperature. In addition, the skin is an accessible and highly cost-effective tissue for etiological studies of some forms of sepsis (e.g., meningococcal purpura) and its involvement defines the prognosis of certain patients (e.g., infective endocarditis).

Abstract
BACKGROUND A combined regimen of rituximab with corticosteroids for the treatment of pemphigus was effective in a prospective randomized controlled trial. OBJECTIVE To assess real-life response to rituximab in patients with pemphigus. METHODS A retrospective cohort of patients with pemphigus treated with ≥1 rituximab cycles (1,000 mg on days 0 and 14). The primary outcome was remission rate after 1 cycle. For efficacy analyses, a minimal 6-month follow-up was required. Adverse events were assessed in all patients. RESULTS The cohort included 117 patients for safety analysis, 108 for efficacy analysis (median follow-up of 33 months). All but one received concomitant corticosteroids, a third also received adjuvants. Overall, 80/108 patients (74%) achieved remission after the first rituximab cycle at a median of 5.5 months. Relapses occurred in 39 patients (49%) at a median of 18 months. Repeating treatment in relapsed patients increased remission rates to 75 and 88% after the second and third cycles, respectively. Adverse events were similar to those of previous publications. Two elderly patients died of infections attributable to rituximab combined with high-dose corticosteroids. CONCLUSION In a large real-life long-term cohort, rituximab with corticosteroids ± adjuvants induced remission in most patients with pemphigus, with relatively favorable safety. Repeating treatment following relapse or remission failure was beneficial.

Abstract
Introduction: Rituximab is slowly getting recognized as a promising steroid-sparing agent in the treatment of moderate to severe cases of pemphigus vulgaris (PV). We evaluated and compared the effectiveness, safety, and cost of therapy of rituximab versus dexamethasone cyclophosphamide pulse (DCP) in Indian patients with PV. Materials and Methods: It is a retrospective data analysis, from the Immunobullous disease clinic in a tertiary centre of eastern India, of management of PV. In our institute we use either rituximab or DCP for the management of moderate to severe cases of PV, depending on that we retrospectively divided the treated cases of PV in two groups. Patients who were treated with rheumatoid arthritis (RA) protocol of rituximab were considered to be group 1. Patients who were treated with DCP were included in group 2. Response was assessed by pemphigus area, and activity score (PAAS), Dermatology life quality index (DLQI); photographic documentation, and blood parameters were monitored. Results: Both groups showed significant improvement in PAAS and DLQI, the improvement was faster and well sustained in the rituximab group. In terms of safety and development of new vesicles, rituximab had a better profile with only 1 patient having adverse effects and none with new vesicles as compared to DCP (3 had adverse effects and 2 developed new vesicles). Conclusions: Rituximab offers the advantage of early and prolonged remission, lesser adverse effects, better effectiveness, less risk of relapses, faster improvement of PAAS, and DLQI. Though rituximab is an expensive drug, but on evaluating the cost of whole therapy, it was seen that rituximab infusions are actually cheaper compared to DCP pulse. We suggest, rituximab can be used as the first-line of therapy for pemphigus vulgaris in the Indian context.

Abstract
B-cells are major effector cells in autoimmunity since they differentiate into plasmocytes that produce pathogenic auto-antibody such as anti-desmoglein antibodies in pemphigus patients. Major advances were obtained using whole B-cell depleting therapies including anti-CD20 antibodies in refractory pemphigus patients that lead to rituximab approval in pemphigus patients in EU and USA. This review summarizes the data supporting the efficacy of rituximab in pemphigus and provides an overview of the reported immunological changes underlying its therapeutic action. Short and long-term remission in pemphigus is explained by the removal of autoreactive B-cells involved in the production of pathogenic IgG auto-antibodies and by enhancement of the appearance of regulatory B-cells that could maintain long term immune tolerance.

Abstract
Pemphigus Vulgaris (PV) is a rare autoimmune blistering disease, which mainly causes mucosal and/or cutaneous lesions. In June 2018, FDA approved Rituximab (RTX)-a B-cell depleting agent-for the management of patients with moderate-to-severe pemphigus. Although the majority of patients respond well to this drug, some do not reach complete remission with a single cycle of RTX. In this review, following an overview of RTX and its clinical outcomes, we have focused on the possible outcomes after RTX therapy in patients with PV. The response is defined into four main categories; complete responders, partial responders, nonresponders, and paradoxical reactions, based on three possibilities of reaching the consolidation phase after 3 months, reaching remission until 6 months, and the ability of corticosteroid tapering in 6 months after RTX administration. Concerning the safety of RTX, three categories of infusion reactions, short and long-term side effects are discussed. Additionally, we have suggested approaches for the evaluation of clinical and serological responses at different critical time-points, including 1, 2, 3, and 6 months after RTX administration. Finally, available markers to predict the response to RTX and research gaps in the field of RTX therapy have been summarized.

Abstract
Bullous diseases are uncommon in children; however, as they have the potential to affect quality of life, occasionally have long-term side effects in the setting of scarring processes, and carry a rare risk of underlying malignancy [e.g., with paraneoplastic pemphigus (PNP)], knowledge of their clinical presentation and treatment options is essential. Given the rarity of these conditions, our current state of knowledge is largely derived from case reports and case series, with a paucity of evidence-based recommendations. In this review, we discuss the clinical presentation of and treatment options for linear immunoglobulin A disease, dermatitis herpetiformis, pemphigus vulgaris, pemphigus foliaceus, PNP, bullous pemphigoid, mucus membrane pemphigoid, epidermolysis bullosa acquisita, and inherited epidermolysis bullosa. In general, when these conditions, except for PNP, occur in childhood, they have a better prognosis than when they occur in adults. Clinical, histopathological, and immunologic features frequently overlap, but distinct differences have also been reported, most commonly in clinical presentation. Treatment is often similar to that in adults, although specific considerations are necessary for a pediatric population.

Abstract
BACKGROUND/OBJECTIVES There is inadequate knowledge regarding rituximab (RTX) administration in autoimmune bullous diseases (AIBDs), disease prevalence, clinical characteristics, and treatment outcomes within pediatric populations due to the rarity of AIBDs affecting the pediatric age group. The aim of this retrospective analysis was to evaluate the effectiveness, safety of RTX, and treatment outcomes in Turkish pediatric patients with pemphigus vulgaris (PV) and to review the literature. METHODS Five patients under 18 years of age and diagnosed with PV received RTX treatment and were identified in four dermatology departments of Turkey. RESULTS The mean age of the patients at the time of RTX therapy initiation was 15 years (range: 11-17 years), and the total duration of follow-up after RTX therapy was 42.6 months (range: 19-60 months). All patients showed a clinical response. At the last visit, complete remission off therapy was achieved in three patients. The remaining two patients achieved partial remission off therapy. No adverse events were observed. CONCLUSIONS This retrospective case series of five pediatric patients showed that RTX treatment can be effective and safe for the treatment of recalcitrant PV in pediatric patients. With increasing evidence, RTX is a good treatment choice in adults and pediatric patients with pemphigus.

Abstract
Pemphigus encompasses a heterogeneous group of autoimmune blistering diseases, which affect both mucous membranes and the skin. The disease usually runs a chronic-relapsing course, with a potentially devastating impact on the patients' quality of life. Pemphigus pathogenesis is related to IgG autoantibodies targeting various adhesion molecules in the epidermis, including desmoglein (Dsg) 1 and 3, major components of desmosomes. The pathogenic relevance of such autoantibodies has been largely demonstrated experimentally. IgG autoantibody binding to Dsg results in loss of epidermal keratinocyte adhesion, a phenomenon referred to as acantholysis. This in turn causes intra-epidermal blistering and the clinical appearance of flaccid blisters and erosions at involved sites. Since the advent of glucocorticoids, the overall prognosis of pemphigus has largely improved. However, mortality persists elevated, since long-term use of high dose corticosteroids and adjuvant steroid-sparing immunosuppressants portend a high risk of serious adverse events, especially infections. Recently, rituximab, a chimeric anti CD20 monoclonal antibody which induces B-cell depletion, has been shown to improve patients' survival, as early rituximab use results in higher disease remission rates, long term clinical response and faster prednisone tapering compared to conventional immunosuppressive therapies, leading to its approval as a first line therapy in pemphigus. Other anti B-cell therapies targeting B-cell receptor or downstream molecules are currently tried in clinical studies. More intriguingly, a preliminary study in a preclinical mouse model of pemphigus has shown promise regarding future therapeutic application of Chimeric Autoantibody Receptor T-cells engineered using Dsg domains to selectively target autoreactive B-cells. Conversely, previous studies from our group have demonstrated that B-cell depletion in pemphigus resulted in secondary impairment of T-cell function; this may account for the observed long-term remission following B-cell recovery in rituximab treated patients. Likewise, our data support the critical role of Dsg-specific T-cell clones in orchestrating the inflammatory response and B-cell activation in pemphigus. Monitoring autoreactive T-cells in patients may indeed provide further information on the role of these cells, and would be the starting point for designating therapies aimed at restoring the lost immune tolerance against Dsg. The present review focuses on current advances, unmet challenges and future perspectives of pemphigus management.

Abstract
Pemphigus is a severe autoimmune blistering disease mediated by pathogenic anti-desmoglein antibodies leading to an inter keratinocyte disjunction. Rituximab is a monoclonal antibody that binds to the CD-20 antigen of B lymphocytes, which causes B-cell depletion and a subsequent reduction in pathogenic autoantibodies. Its therapeutic role in pemphigus has been progressively growing with increasing evidence of successful outcomes. Rituximab was initially off-labeled used as an alternative in patients with recalcitrant or relapsing pemphigus and in patients with contraindications to systemic corticosteroids. Recently, a large randomized clinical trial has shown that first-line use of rituximab combined with short-term prednisone regimen was both more effective and potentially safer than a standard regimen of high doses of corticosteroids in patients with moderate to severe pemphigus.

Abstract
Therapeutics of autoimmune bullous disease has seen a major shift of focus from more global immunosuppression to targeted immunotherapy. Anti CD 20 monoclonal antibody Rituximab revolutionized the therapeutics of autoimmune bullous disease particularly pemphigus. Though it is still being practiced off-label, evidences in the form of RCT and meta analysis are now available. Other novel anti CD 20 monoclonal antibodies like ofatumumab, veltuzumab, and ocrelizumab, tositumomab or obinutuzumab/GA101 may add to the therapeutic options in coming days. Beyond anti CD 20 monoclonal antibodies other options that show promise at least in select scenario are omalizumab, TNF inhibitors plasmapheresis and intravenous immunoglobulin. The present article will discuss the role of rituximab and other newer therapeutics in the treatment of autoimmune blistering disease, especially pemphigus and suggests their positions in the therapeutic ladder.

Abstract
INTRODUCTION Pemphigus vulgaris (PV) is a chronic, autoimmune, vesiculobullous disease. As a result of the relative rarity of PV, published randomized controlled trials (RCTs) are limited, which makes it difficult to evaluate the efficacy of different treatment regimens in this disease. This also precludes conduct of a meta-analysis. METHODS English-language publications describing treatment outcomes of patients with PV were identified by searches of electronic databases through May 2015, and additionally by review of the bibliography of these publications. A total of 89 papers, which included 21 case reports, 47 case series, 8 RCTs, and 13 observational studies, were identified. The findings from these publications, including information on disease course and prognosis, medications used, treatment responses, and side effects, are summarized in the tables and text of this review. RESULTS Prior to availability of corticosteroid therapy, PV had a high fatality rate. Early publications from the 1970s reported high-dose, prolonged corticosteroid use and significant associated side effects. Later reports described use of corticosteroids along with steroid-sparing adjuvants, which allows a reduction in the total dose of corticosteroids and a reduction in observed mortality and morbidity. For the majority of patients in these reports, a long-term course on medications lasting about 5-10 years was observed; however, subgroups of patients requiring shorter courses or needing longer-term therapy have also been described. Early diagnosis of PV and early initiation of treatment were prognostic factors. In recent publications, commonly used initial regimens include corticosteroids in combination with mycophenolate or azathioprine; whereas, for patients with inadequate response to these regimens, adjuvants such as intravenous immunoglobulin (IVIg) or rituximab are used. CONCLUSION The review findings emphasize the importance of early diagnosis, early initiation of treatment, and use of steroid-sparing adjuvants to allow a reduced total dose and duration on corticosteroids. Also highlighted is the need for more RCTs.

Abstract
BACKGROUND Rituximab is a promising therapy in pemphigus. However, there is no consensus on optimum dose. OBJECTIVES To compare the efficacy, in terms of clinical and immunological outcomes in patients with pemphigus, of a high (2 × 1000 mg) vs. a low dose (2 × 500 mg) of rituximab. METHODS This was a randomized, observer-blinded trial wherein 22 patients with pemphigus were randomized into two treatment groups. Patients received either two doses (day 0 and day 15) of 1000 mg rituximab or 500 mg rituximab, and were followed up for 48 weeks. Clinical activity was assessed by a blinded investigator. Indices of enzyme-linked immunosorbent assays (ELISAs) for desmoglein (Dsg)1 and Dsg3, and CD19 cell count were examined at regular intervals. RESULTS There was no statistically significant difference in early and late clinical end points, and total cumulative dose of corticosteroids between the two groups. At week 40, the fall in Ikeda severity score was significantly more in the 2 × 1000 mg group than in 2 × 500 mg group (P = 0·049). Patients in the 2 × 500 mg group received a significantly higher cumulative dose of azathioprine (P = 0·018). The ELISA indices of Dsg1 and Dsg3 showed a statistically significant decline in the 2 × 1000 mg group only. B cell repopulation occurred earlier in the 2 × 500 mg group by 8 weeks. CONCLUSIONS A few clinical and immunological study parameters have suggested improved outcomes in patients receiving high-dose (2 × 1000 mg) rituximab.

Abstract
Pediatric pemphigus vulgaris (PV) is a rare autoimmune bullous dermatosis that poses a diagnostic and therapeutic challenge. Rituximab, an anti-CD20 monoclonal antibody, is an important medication in adult PV but has rarely been used to treat pediatric disease. We describe successful rituximab therapy in a 4-year-old, the youngest patient with PV ever reported to receive rituximab. A live attenuated vaccination was later given without incident. We also review rituximab clinical outcomes, toxicity, dosing protocols, and relapse in children with PV.

Abstract
BACKGROUND Autoimmune blistering diseases (AIBDs) are rare in children and their prevalence in Singapore is unclear. We aimed to investigate the clinical and immunopathologic characteristics of children diagnosed with AIBDs in Singapore. MATERIALS AND METHODS The clinical and histology databases at the National Skin Centre in Singapore were searched to identify patients younger than 18 years old diagnosed with an AIBD from January 1, 1998, through December 31, 2012. Patient demographic characteristics, presentation, triggers, investigations, treatments, and disease course were analyzed. RESULTS Twelve patients with AIBDs were identified; five (41.7%) had linear immunoglobulin A disease (LAD); two (16.7%) each had pemphigus vulgaris (PV), bullous pemphigoid, and bullous systemic lupus erythematosus; and one (8.3%) had pemphigus foliaceus. Four (33.3%) were female and eight (66.7%) male. The mean age of onset was 8.7 years (range 2-17 years). Most patients were treated with steroids and adjuvant immunosuppressants. Intravenous rituximab was used effectively in a patient with recalcitrant PV. The mean follow-up was 2.35 years (range 0.17-7.33 years). As of the last follow-up, four (33.3%) patients were in complete remission off therapy, two (16.7%) were in complete remission on therapy, four (33.3%) were in partial remission on therapy, and two (16.7%) were lost to follow-up. CONCLUSION Consistent with the existing literature, our study shows that LAD is the most common cause of AIBDs in children. Although common in the West, dermatitis herpetiformis was not identified in the current study. Intravenous rituximab may be considered in recalcitrant childhood PV, but vigilant monitoring for side effects is crucial. Immunohistopathologic evaluation is important and repeat biopsies may be of value in patients with atypical disease courses.

Abstract
Rituximab is a chimeric monoclonal antibody that selectively binds to the CD20 molecule on B cells, resulting in their lysis. In autoimmune blistering diseases, the auto-antibody-producing B cells are destroyed and auto-antibody levels are reduced or eliminated. In the majority of patients, rituximab produces rapid clinical response and early resolution. In part, this accounts for the increased use of rituximab. Rituximab does not distinguish normal from pathologic B cells. Hence, shortly after its use, B-cell levels are zero and remain so for several months. In most patients, the use of systemic corticosteroids and immunosuppressive agents are continued after rituximab therapy, while their dosages are significantly decreased. In the majority of patients rituximab is used according to the protocol used in treating lymphoma patients or patients with rheumatoid arthritis. Approximately 50% of patients experience a relapse, requiring additional therapy. Serious adverse events and fatal outcomes have been reported, although their incidence is less than that observed with conventional therapy. Nonetheless, the causes, i.e. infections and septicemia, are similar. Several gaps exist in our understanding of how to optimally benefit from the use of this valuable biological agent. Future studies need to be targeted in designing and implanting protocols that maximize the benefit of rituximab and result in producing sustained prolonged remissions with minimal adverse events and a high quality of life.

Abstract
Rituximab is a monoclonal therapeutic anti-CD20 antibody that has been approved for use in lymphoma and rheumatoid arthritis. Over the past decade several reports based on case series and observational studies have recorded the benefits of rituximab in particular groups of dermatological patients. Off-label use of rituximab in many dermatological indications is not uncommon in many countries in the world. This article reviews the available data that may be of use to the practicing dermatologist. Because of its potential complications, paucity of clinical data, and cost considerations, rituximab is favoured only when standard systemic therapies fail or corticosteroids are absolutely contraindicated. Further research is required in this field.

Abstract
Pemphigus foliaceus (PF) and Behçet's disease (BD) are immune-mediated conditions which are usually treated with corticosteroids, immunosuppressants, and, when refractory, with biologic agents. In both diseases, interleukin (IL)-6 serum levels are increased driving the immune-mediated inflammatory process. Tocilizumab is a humanized monoclonal antibody, targeting IL6-receptor, used in the treatment of rheumatoid arthritis. Besides the current indication, it has been recently administered to patients with refractory immune inflammatory diseases as an off-label treatment. Here, we report the case of a woman affected with PF and BD, who did not respond to corticosteroids, immunosuppressants, and biologic agents including adalimumab, anakinra, and infliximab. A complete, long-lasting, clinical, and serological remission was achieved only with tocilizumab. To the best of our knowledge, the association between PF and BD has never been reported. Moreover, only two cases of BD and no cases of PF treated with tocilizumab have been described to date. A literature review on the use of biologic agents on patients with PF and BD was also carried out.

BACKGROUND Dexamethasone cyclophosphamide pulse (DCP) therapy is an established mode of treatment for pemphigus in India. AIMS To assess the therapeutic benefit of additional DCPs (phase II, consolidation phase) versus immediate oral cyclophosphamide, usually used in phase III (maintenance phase), after initial DCP therapy (phase I) and to assess which laboratory test (DIF or ELISA) will reflect the clinical relapse best. METHODS Nineteen newly recruited patients of pemphigus vulgaris (PV) received monthly DCPs in phase I and were then randomized into two groups. Group A (10 patients) received monthly DCPs for nine months and Group B (nine patients) received only oral cyclophosphamide for nine months. Direct immunofluorescence (DIF) and enzyme-linked immunosorbent assay (ELISA) were tested before starting DCP regimen, and at 0,3,6,9 months after randomization. RESULTS Clinical relapse by the end of follow-up period occurred in only one patient in each group. In these cases, DIF became (again) positive before the relapse. No statistically significant difference between the two groups was found at three, six and nine months by ELISA indices and DIF grading. CONCLUSION Although the DCP regimen is the standard therapy for pemphigus in India, we found no difference in the clinical outcome between patients receiving nine DCPs in phase II and patients shifted directly from phase I to III. Periodic testing using DIF and Dsg ELISA were found to be useful to monitor disease activity and predict a relapse. Further large scale studies are required to assess if patients can be shifted directly from phase I to III and maintained only on oral cyclophosphamide.

Abstract
INTRODUCTION Rituximab is increasingly used in patients with pemphigus vulgaris (PV) who are nonresponders to conventional therapy. METHODS A PubMed search was conducted using the words pemphigus vulgaris and rituximab therapy from papers published between 2000 and 2012. Two protocols were used. In the lymphoma protocol, patients received four weekly infusions of rituximab (dose 375 mg/m(2)). The rheumatoid arthritis (RA) protocol consisted of two infusions of 1,000 mg each 15 days apart. The variables recorded from each study included clinical remission off or on therapy, relapse rate, incidence of serious adverse events, concomitant therapies, duration of follow-up, and when available, levels of B cells and autoantibodies. RESULTS Forty-two studies were found, which reported 272 patients; 180 were treated by the lymphoma protocol and 92 by the RA protocol. Both protocols were effective in treating recalcitrant PV. The lymphoma protocol had a lower response rate, relapse rate and serious infections, but higher mortality, and there were nonresponders. The RA protocol produced a higher response rate, relapse rate, number of infections, but lower mortality rate, and lacked nonresponders. The cumulative follow-up for patients treated with the lymphoma protocol was 15.44 months (range 1-41) and 21.04 months (range 8.35-29) for the RA protocol. A major concern in both protocols was the high infection rates, some of which were fatal. A different protocol using a combination of rituximab with intravenous immunoglobulin in a defined manner with a definitive endpoint, used in a limited cohort of patients, showed promising results. CONCLUSION Neither protocol produced a sustained clinical remission and both required continued systemic therapy. Before initiation of treatment, physicians should have a specific goal and endpoint and be aware of its potential side effects and lack of information on its long-term effects. Patients should be carefully monitored during and after therapy.
