It has numerous risk factors and triggers, including an aging population with several comorbidities and drug exposure. In the published paper, we reported a case about a 32 years old male patient with unknown medical conditions who presented with erythematous patches and plaques on the scalp, face, and trunk with scattered blisters two weeks after initiating doxycycline treatment for folliculitis. The exact pathogenesis of the drug-reaction in drug- associated bullous pemphigoid (DABP) remains controversial. In conclusion, it is crucial for clinicians to be aware of DABP when prescribing doxycycline. The purpose of this case report is to raise awareness of the possible association between bullous pemphigoid and doxycycline.展开更多

The Systemic Immune-Inflammation Index (SII) and Neutrophil-Lymphocyte Ratio (NLR), are inflammatory markers used to assess the body’s immune-inflammatory response. Objectives: The study aims to evaluate the significance of hematologic markers, specifically the Systemic Immune-Inflammation Index (SII) and Neutrophil-Lymphocyte Ratio (NLR), as diagnostic predictors of bullous pemphigoid (BP) and pemphigus vulgaris (PV). Methods: A retrospective study of 64 patients (36 with BP and 28 with PV). Patient clinical data: age, gender, complete blood count, autoimmune antibody levels (Dsg1, 3 and BP180, 230), IgE and C-reactive protein, and history of hypertension, diabetes, brain infarction, and coronary heart disease. The data was analyzed using SPSS. Results: The study involved 36 (56.3%) diagnosed with bullous pemphigoid (BP) and 28 (43.75%) with pemphigus vulgaris (PV). The average age in BP was 71 ± 8 and 52 ± 13 in PV. Laboratory findings showed high levels of Dsg1, Dsg3, neutrophil count, and lymphocyte count in PV, while high levels of eosinophils with a significant increase in C-reactive protein (CRP) in BP. Blood biomarkers, including NLR, PLR, SII, MPV, CRP, and IgE, proved an overall of 84.4% in disease prediction. Dsg1, Dsg3, BP180, and BP230 showed an overall of 88.1%. No significant relationship was noted between NLR, SII, and patients with comorbidities. Conclusion: The study highlights the diagnostic potential of SII and NLR in addition to hematologic markers in BP and PV, emphasizing their role in early diagnosis and therapeutic interventions, requiring further validation in larger patient cohorts.展开更多

Its morbidity and mortality have remained high owing to complications of extensive skin involvement as well as its conventional steroid therapy. We reviewed the medical literature and found indicators of an autoimmune etiology for its pathogenesis triggering genetically predisposed patients. Objective: to evaluate, prospectively, the role of Rituximab (R) therapy in its persistent, severe and extensive form. Patients and methods: A total of 12 patients, with disease duration of 6 ± 1 months, were treated with yearly R infusions (1 g followed by 1 g 2 weeks later). Results: Significant clinical improvement was achieved as documented by decrease in total score of Bullous Pemphigoid Disease Area Index from 60 ± 3 to 6 ± 2 that persisted for 26 ± 11 months of follow up. Moreover, IBP autoantibodies (anti-BP 180 and anti-320 IgG) levels fell from to 91 ± 3 and 81 ± 2 to 8 ± 2 and 9 ± 2, respectively. Conclusions: R is a safe and effective treatment for severe IBP and such response further confirms its autoimmune pathogenesis.展开更多

It typically presents with tense bullae and severe pruritus. Non-bullous pemphigoid is a subtype of BP characterized by lacking the typical bullae formation with different presentations including erythematous, eczematous, urticarial, polycyclic, targetoid, nodular, lichenoid, vesicular and erythrodermic. Aim: to document a new case presentation of urticarial BP who was treated for several years as chronic urticarial and chronic eczema. Case Report: A 56-year-old male patient presented with a history of recurrent severely pruritic urticarial wheals for 4 years duration involving the lower abdomen, lower back, upper and lower extremities associated with excoriations, keratosis, and post-inflammatory hyperpigmentations on resolved sites, diagnosed as urticarial BP on histopathology & direct immunofluorescence study (DIF) and was improved on systemic doxycycline therapy. Conclusion: BP can be presented with atypical manifestation. Urticarial BP is a rare variant of non-bullous pemphigoid that should be taken into consideration in the differential diagnosis of an atypical urticarial wheal not responding to conventional therapy.展开更多

For the purpose of this review, we will describe pseudopemphigoid as caused by topical drugs, the most common etiology with ocular manifestations, and as caused by the pemphigus disease, a more rare etiology. Specifically, we will discuss the ophthalmological features of drug-induced cicatricial conjunctivitis, pemphigus vulgaris, and paraneoplastic pemphigus. Other etiologies of pseudopemphigoid exist that will not be described in this review including autoimmune or inflammatory conditions such as lichen planus, sarcoidosis, granulomatosis with polyangiitis(Wegener's granulomatosis), erythema multiforme(minor, major, and Stevens-Johnson syndrome), bullous pemphigoid, skin-dominated linear IgA bullous dermatosis, and skin-dominated epidermolysis bullosa acquisita. Prompt diagnosis of the underlying etiology in pseudopemphigoid is paramount to the patient's outcome as certain diseases are associated with a more severe clinical course, increased ocular involvement, and differential response to treatment. A completehistory and ocular examination may find early cicatricial changes in the conjunctiva that are important to note and evaluate to avoid progression to more severe disease manifestations. When such cicatricial changes are noted, proper diagnostic techniques are needed to help elucidate a diagnosis. Lastly, collaboration between ophthalmologists and subspecialists such as dermatologists, pathologists, immunologists, and others involved in the care of the patient is needed to ensure optimal management of disease.展开更多

Study design: Prospective and observational study conducted with 69 patients from May 2013 to May 2014 at the Dermatology Outpatient Clinic of the Clinical Hospital, University of São Paulo Medical School, Brazil. Data were analyzed for frequency in absolute values, percentage and correlation using the Chi-square test. Results: 84.1% of the patients had oral manifestations of vesiculobullous diseases (p = 0.001);25% had gingival lesions;18.2% had lesions in the buccal mucosa, and 17.6% in the lips, with no correlation between the location and the type of disease (p = 0.990). Among all patients with bullous pemphigoid, linear IgA dermatosis, and mucous membrane pemphigoid, 59 (93.6%) patients had gingival inflammation of dental origin but without significant correlation (p = 0.42). There was correlation between pemphigus vulgaris and periodontal disease (p = 0.05). Conclusion: Gingival inflammation seems to interfere negatively with the clinical course of these diseases. Further studies should be conducted to better clarify the interrelations between dental and gingival state, and between vesiculobullous diseases and oral involvement.展开更多

BP is characterized clinically by tense bullae on the extremities and trunk, histopathologically by subepi-dermal blisters with eosinophilic infiltration, and immunologically by autoantibodies to BP180 and BP230. Direct immunofluorescence of perilesional skin shows depositions of IgG and C3 in the basement membrane zone(1)BP rarely shows prominent milia formation, which is a hallmark of epidermolysis bullosa acquisita. We herein describe a 53-year-old man with refractory BP showing numerous milia during recovery.展开更多

Patients diagnosed with OCP were examined by clinical history, slit-lamp biomicroscopy features and IVCM images. The results of direct immunofluorescence(DIF) biopsies and indirect immunofluorescence(IIF) were also recorded. Local and systemic immunosuppressive therapy were administered and adjusted according to response.·RESULTS: A total of 12 consecutive OCP patients(7male, 5 female; mean age 60.42 ±10.39y) were recruited.All patients exhibited bilateral progressive conjunctival scarring and recurrent chronic conjunctivitis was the most frequent clinical pattern. The mean duration of symptoms prior to diagnosis of OCP was 2.95 ±2.85y(range: 5mo to 10y). The Foster classification varied from stage I to IV and 20 eyes(83%) were within or greater than Foster stage Ⅲ on presentation. Two of the 12patients(17%) demonstrated positive DIF; 3 of the 12(25%) patients reported positive IIF. The mean duration of the follow-up period was 20.17 ±11.88mo(range: 6 to48mo). IVCM showed variable degrees of abnormality in the conjuctiva-cornea and conjuctival scarring was detected in all the involved eyes. Corneal stromal cell activation and dendritic cell infiltration presented asocular surface inflammation, ocular surface keratinization along with the destroyed Vogt palisades was noted in eyes with potential limbal stem cell deficiency. After treatment, remission of ocular surface inflammation was achieved in all the patients, 18 eyes(75%) remained stable, 6 eyes(25%) had recurrent conjunctivitis and cicatrization in 2 eyes(8%) was progressing.· CONCLUSION: As an autoimmune disease, OCP manifests as variable degrees of clinical and laboratory abnormalities with both local and systemic immunosuppressive treatment playing important roles in disease therapy. IVCM can be as a valuable non-invasive technique to assess ocular surface changes in a cellular level with a potential value for providing diagnostic evidence and monitoring therapeutic effects during follow-up.展开更多

An overview of the different forms of SABD are discussed including bullous pemphigoid (BP), epidermolysis bullosa acquisita (EBA), cicatricial pemphigoid (CP), bullous systemic lupus erythematosus (BSLE), and Anti-p200 pemphigoid. Emphasis on recent advancement is presented. In recent years, improved knowledge of the mechanisms of intercellular and cell-matrix adhesion has led to better understanding of the blistering process in some SABD. Defects of such structures cause the subepidermal bullous diseases and have also led to the discovery of new diseases (e.g. anti-p200-pemphigoid). Recent studies have outlined the important role of autoantibodies, mast cell lymphocytes and their cytokines in pathogenesis of SABD.展开更多

文摘Bullous pemphigoid (BP) is the most prevalent autoimmune sub-epidermal blistering disease that affects mainly the elderly and could lead to serious morbidity. It has numerous risk factors and triggers, including an aging population with several comorbidities and drug exposure. In the published paper, we reported a case about a 32 years old male patient with unknown medical conditions who presented with erythematous patches and plaques on the scalp, face, and trunk with scattered blisters two weeks after initiating doxycycline treatment for folliculitis. The exact pathogenesis of the drug-reaction in drug- associated bullous pemphigoid (DABP) remains controversial. In conclusion, it is crucial for clinicians to be aware of DABP when prescribing doxycycline. The purpose of this case report is to raise awareness of the possible association between bullous pemphigoid and doxycycline.

文摘Immunotherapy is an important treatment modality in cancer,but it can also cause adverse reactions,with skin toxicity being the most common.The increasing number of immune checkpoint inhibitors being used in the clinic will inevitably cause an increase in the rate of adverse skin reactions that markedly affect the patient's quality of life.A 58-year-old patient with intrahepatic cholangiocareinoma developed bullous pemphigoid(BP)nearly a year after using immune checkpoint inhibitors,which is different from what has been reported inthe literature within two weeks of treatment.Pathologically,the skin biopsy diagnosis was epidermal hyperplasia and focal sub-epidermal pustule formation,consistent with drug-induced dermatitis.The patient was treated with methylprednisolone,minocyeline,colchicine,nicotinamide,triamcinolone,and traditional Chinese medicine decoction.No new blisters developed after 1 week of treatment.The medication was gradually discontinued,and BP did not recur.Clinicians should carefully consider the risk-benefit ratio when using PD-1 inhibitors,particularly concerning rash severity.Further studies are needed to investigate the relationship between adverse skin reactions and drug efficacy.
文摘BACKGROUND There is limited literature on managing the airway of patients with linear immunoglobulin A(IgA)bullous dermatosis,a rare mucocutaneous disorder that leads to the development of friable bullae.Careful clinical decision making is necessary when there is a risk of bleeding into the airway,and a multidisciplinary team approach may lead to decreased patient morbidity during these high-risk scenarios,especially when confronted with an unusual cause for bleeding.CASE SUMMARY A 45-year-old African American female presented to our ambulatory surgical center for right corneal transplantation due to corneal perforation after blunt trauma in the setting of cicatricial conjunctivitis and diffuse corneal neovascularization from linear IgA bullous dermatosis.The diagnosis of IgA dermatosis was recent,and the patient had been lost to follow-up.The severity of the disease and extent of airway involvement was unknown at the time of the surgery.Significant airway bleeding was noticed upon intubation and the otorhinolaryngology team had to be called to the operating room.The patient required transfer to the intensive care unit where a multidisciplinary team was involved in her case.The patient was extubated on postoperative day 4.CONCLUSION A multidisciplinary approach to treating this disease is the best course of action before a surgical procedure.In our case,key communication between the surgery,anesthesia,and dermatology teams led to the quick and safe treatment of our patient’s disease.Ambulatory surgery should not be considered for these cases unless they are in full remission and there is no mucous membrane involvement.
文摘Introduction:Bullous pemphigoid is an acquired autoimmune bullous skin disease that occurs in the elderly,and nail involvement is relatively rare.Kaposi sarcoma(KS) is a rare opportunistic tumor in patients with iatrogenic immunosuppression and is rarely associated with autoimmune bullotic disease.Case presentation:The patient was diagnosed with bullous pemphigoid based on her history,bullous pemphigoid antibody,and skin pathological examination.And nail involvement occurred 20 days prior to the recurrence of the disease.Moreover,KS occurred during high-dose glucocorticoid therapy in this patient.Discussion:The patient was admitted to hospital because of a five-month history of erythema and blisters and a one-month history of nodules and plaques.The diagnosis of bullous pemphigoid was followed by treatment with glucocorticoids and intravenous gamma globulin.During treatment,the disease recurred due to discontinuation of glucocorticoids.There were erythema and blisters all over the body,and purple nodules,plaques appeared in the base of some blisters.Pathological examination of nodules was consistent with KS.In addition,nail involvement occurred 20 days before recurrence.The particularity of this case lies in the simultaneous occurrence of nail involvement,bullous pemphigoid,and KS.Conclusion:Patients with autoimmune bullous skin disease may suddenly develop abnormal nails,and such patients should be vigilant about recurrence of the disease.Doctors should be aware of the possibility of KS when rapidly progressing purplish red plaques or nodules appear in patients receiving high doses of corticosteroids or immunosuppressants.

文摘BACKGROUND Malignant glaucoma,caused by aqueous misdirection,is a challenging postsurgical complication presented with normal/high intraocular pressure and shallowing of the central and peripheral anterior chambers.Its incidence is about 0.6%-4.0%.It can be secondary to filtering surgeries,laser iridotomy,and cataract surgery.Short axial length and a history of angle closure glaucoma are its main risk factors.Here,we report a bilateral malignant glaucoma with bullous keratopathy in the patient’s left eye.CASE SUMMARY We present a case of bilateral malignant glaucoma.The cause of malignant glaucoma for each eye of this patient was different.Hence,the management strategy and selection of surgical methods were also different.However,the normal anterior chamber was ultimately maintained,and maximum visual function was preserved.Even though the left eye received multiple surgeries and corneal endothelial decompensation occurred,the formation of a retroendothelial fibrous membrane partially compensated for the function of the corneal endothelium.CONCLUSION The formation of a retroendothelial fibrous membrane partially compensated for the function of the corneal endothelium.
文摘With the widespread use of immunotherapy in numerous solid tumours,immunotherapy-related adverse events(irAEs)have started to emerge and bring new challenges for clinicians to manage.Among established irAEs,dermatologic toxicity is one of the most common toxicities;it is often mild but can be severe and potentially life-threatening,such as bullous pemphigoid.Here,we report a case of nivolumab-mediated severe,extensive,refractory bullous pemphigoid involving both skin and oral mucosa in a patient with metastatic renal cancer.We also summarise a list of selected case reports of immunotherapy-induced bullous pemphigoid by literature review.We highlight various presentations,investigations and managements of this type of skin irAEs.Meantime,we would like to discuss the correlation of skin irAEs incidence rate with immunotherapy drug benefit and resistance.
文摘Esophagitis dissecans superficialis(EDS)is a rare and severe endoscopic finding characterized by sloughing of large fragments of esophageal mucosal lining.Although EDS has been reported in association with serious illnesses and certain medications,the pathophysiological association of autoimmune bullous dermatoses with EDS has gained remarkable attention.Among these dermatoses,pemphigus vulgaris and pemphigoid frequently present with various types of esophageal involvement including EDS.We review the pathophysiology and clinical features of this involvement with the presentation of our experiences.The importance of endoscopic evaluation of this entity is discussed.

文摘Pseudopemphigoid can cause a chronic cicatricial conjunctivitis that is clinically identical to the manifestations seen in mucous membrane pemphigoid, a disorder with a common clinical phenotype and multiple autoimmune links. For the purpose of this review, we will describe pseudopemphigoid as caused by topical drugs, the most common etiology with ocular manifestations, and as caused by the pemphigus disease, a more rare etiology. Specifically, we will discuss the ophthalmological features of drug-induced cicatricial conjunctivitis, pemphigus vulgaris, and paraneoplastic pemphigus. Other etiologies of pseudopemphigoid exist that will not be described in this review including autoimmune or inflammatory conditions such as lichen planus, sarcoidosis, granulomatosis with polyangiitis(Wegener's granulomatosis), erythema multiforme(minor, major, and Stevens-Johnson syndrome), bullous pemphigoid, skin-dominated linear IgA bullous dermatosis, and skin-dominated epidermolysis bullosa acquisita. Prompt diagnosis of the underlying etiology in pseudopemphigoid is paramount to the patient's outcome as certain diseases are associated with a more severe clinical course, increased ocular involvement, and differential response to treatment. A completehistory and ocular examination may find early cicatricial changes in the conjunctiva that are important to note and evaluate to avoid progression to more severe disease manifestations. When such cicatricial changes are noted, proper diagnostic techniques are needed to help elucidate a diagnosis. Lastly, collaboration between ophthalmologists and subspecialists such as dermatologists, pathologists, immunologists, and others involved in the care of the patient is needed to ensure optimal management of disease.
文摘Kaposi&#39;s sarcoma (KS) is a rare,malignant vascular.tumor of the skin,mucosa,and viscera with an increased incidence in human immunodeficiency virus (HIV)-positive patients.According to the clinical characteristics and the affected population,four clinical types of KS have been described successively:classic,endemic to Africa,acquired immunodeficiency syndrome (AIDS)-associated,and immunosuppression associated type.Bullous pemphigoid (BP) is an acquired autoimmune bullous skin disease that frequently occurs in the elderly and is characterized by intraepidermal blisters and immunoglobulin G (IgG) deposits on the basement membrane.A few cases of KS have occurred in immunosuppressed patients with BP.Here,we report a Chinese female patient diagnosed with immunosuppression associated KS that was induced by the short-term use of immunosuppressive agents for BP.We also present a review of the literature on immunosuppressed KS with BP and discuss the potential role of human herpesvirus-8 (HHV-8) in the pathogenic mechanism.
文摘Objective: To determine the occurrence of oral manifestations, gingival index, dental state and associated therapeutic aspects in patients with vesiculobullous diseases. Study design: Prospective and observational study conducted with 69 patients from May 2013 to May 2014 at the Dermatology Outpatient Clinic of the Clinical Hospital, University of São Paulo Medical School, Brazil. Data were analyzed for frequency in absolute values, percentage and correlation using the Chi-square test. Results: 84.1% of the patients had oral manifestations of vesiculobullous diseases (p = 0.001);25% had gingival lesions;18.2% had lesions in the buccal mucosa, and 17.6% in the lips, with no correlation between the location and the type of disease (p = 0.990). Among all patients with bullous pemphigoid, linear IgA dermatosis, and mucous membrane pemphigoid, 59 (93.6%) patients had gingival inflammation of dental origin but without significant correlation (p = 0.42). There was correlation between pemphigus vulgaris and periodontal disease (p = 0.05). Conclusion: Gingival inflammation seems to interfere negatively with the clinical course of these diseases. Further studies should be conducted to better clarify the interrelations between dental and gingival state, and between vesiculobullous diseases and oral involvement.
文摘Introduction Bullous pemphigoid (BP) is an autoimmune blistering disease that affects patients of advanced age. BP is characterized clinically by tense bullae on the extremities and trunk, histopathologically by subepi-dermal blisters with eosinophilic infiltration, and immunologically by autoantibodies to BP180 and BP230. Direct immunofluorescence of perilesional skin shows depositions of IgG and C3 in the basement membrane zone(1)BP rarely shows prominent milia formation, which is a hallmark of epidermolysis bullosa acquisita. We herein describe a 53-year-old man with refractory BP showing numerous milia during recovery.

文摘AIM: To describe the clinical features and microstructural characteristics assessed by in vivo confocal microscopy(IVCM) in patients with ocular cicatricial pemphigoid(OCP).· METHODS: A descriptive, uncontrolled case series study. Patients diagnosed with OCP were examined by clinical history, slit-lamp biomicroscopy features and IVCM images. The results of direct immunofluorescence(DIF) biopsies and indirect immunofluorescence(IIF) were also recorded. Local and systemic immunosuppressive therapy were administered and adjusted according to response.·RESULTS: A total of 12 consecutive OCP patients(7male, 5 female; mean age 60.42 ±10.39y) were recruited.All patients exhibited bilateral progressive conjunctival scarring and recurrent chronic conjunctivitis was the most frequent clinical pattern. The mean duration of symptoms prior to diagnosis of OCP was 2.95 ±2.85y(range: 5mo to 10y). The Foster classification varied from stage I to IV and 20 eyes(83%) were within or greater than Foster stage Ⅲ on presentation. Two of the 12patients(17%) demonstrated positive DIF; 3 of the 12(25%) patients reported positive IIF. The mean duration of the follow-up period was 20.17 ±11.88mo(range: 6 to48mo). IVCM showed variable degrees of abnormality in the conjuctiva-cornea and conjuctival scarring was detected in all the involved eyes. Corneal stromal cell activation and dendritic cell infiltration presented asocular surface inflammation, ocular surface keratinization along with the destroyed Vogt palisades was noted in eyes with potential limbal stem cell deficiency. After treatment, remission of ocular surface inflammation was achieved in all the patients, 18 eyes(75%) remained stable, 6 eyes(25%) had recurrent conjunctivitis and cicatrization in 2 eyes(8%) was progressing.· CONCLUSION: As an autoimmune disease, OCP manifests as variable degrees of clinical and laboratory abnormalities with both local and systemic immunosuppressive treatment playing important roles in disease therapy. IVCM can be as a valuable non-invasive technique to assess ocular surface changes in a cellular level with a potential value for providing diagnostic evidence and monitoring therapeutic effects during follow-up.
文摘Subepidermal autoimmune bullous diseases (SABD) are some autoimmune skin diseases that can present in a variety of forms and can be a challenging disease to treat. An overview of the different forms of SABD are discussed including bullous pemphigoid (BP), epidermolysis bullosa acquisita (EBA), cicatricial pemphigoid (CP), bullous systemic lupus erythematosus (BSLE), and Anti-p200 pemphigoid. Emphasis on recent advancement is presented. In recent years, improved knowledge of the mechanisms of intercellular and cell-matrix adhesion has led to better understanding of the blistering process in some SABD. Defects of such structures cause the subepidermal bullous diseases and have also led to the discovery of new diseases (e.g. anti-p200-pemphigoid). Recent studies have outlined the important role of autoantibodies, mast cell lymphocytes and their cytokines in pathogenesis of SABD.
