Impetigo herpetiformis (IH) is a very rare and specific pustular dermatosis of pregnancy that can be life-threatening for both mother and child. This entity is currently considered as a variant of pustular psoriasis. We report an observation of a 35-year-old female patient who presented with extensive erythematous-pustular plaques for which the diagnosis of impetigo herpetiformiswas made clinically and histologically. The lesions appeared in the third trimester of pregnancy without fetal or maternal impact. The treatment was prednisone, vitamin D supplementation and a macrolide for 10 days.

Blasenbildende Autoimmunerkrankungen sind seltene, meist schwere Erkrankungen von Haut und Schleimhäuten, die immunologisch durch zirkulierende Antikörper gegen Adhäsionsmoleküle der Epidermis und der dermoepidermalen Junktionszone charakterisiert sind; diese führen zum Adhäsionsverlust von Haut und Schleimhäuten und klinisch zur Ausbildung von Blasen oder Erosionen. Beim Pemphigus findet der Adhäsionsverlust in der Epidermis statt, während beim Pemphigoid, der linearen IgA-Dermatose, der Epidermolysis bullosa acquisita und der Dermatitis herpetiformis Duhring der Adhäsionsverlust subepidermal, d. h. innerhalb oder unterhalb der dermoepidermalen Basalmembranzone statt findet. Die Autoantigene dieser Erkrankungen sind weitesgehend identifiziert und charakterisiert. Die Diagnostik bullöser Autoimmundermatosen basiert auf Histologie und direkter Immunfluoreszenz perilesionaler Haut sowie dem serologischen Autoantikörpernachweis mittels indirekter Immunfluoreszenz und rekombinanten Proteinen. Therapeutisch erfolgt in den meisten Fällen die systemische Therapie mit Glukokortikoiden, die mit adjuvanten Immunsuppressiva kombiniert werden, um die Steroiddosis kurzfristig reduzieren zu können. Eine prospektive Studie beim Pemphigus zeigt, dass die zusätzliche Behandlung mit Azathioprin, Mykophenolat Mofetil bzw. Cyclophosphamid die kummulative Steroiddosis bis zur klinischen Remission reduziert. Beim bullösen Pemphigoid führt die topische Therapie mit Clobetasol ohne die unerwünschten Nebenwirkungen der systemischen Steroidtherapie zu kompletten klinischen Remissionen. Die therapeutische B-Zelldepletion mit Rituximab als Second Line-Therapie hat die Prognose des Pemphigus wesentlich verbessert. Bei weiteren Erkrankungen wie der Dermatitis herpetiformis und Epidermolysis bullosa acquisita liegen vergleichbare, kontrollierte Therapiestudien bislang noch nicht vor.

Estimado editor, Por medio de la presente nos gustaría traer a discusión la importancia que tiene la enfermedad celiaca (EC), también conocida como esprúe celiaco o enteropatía sensible al gluten, la cual corresponde a una enfermedad autoinmune desencadenada por la ingesta de gluten en individuos predispuestos genéticamente (1). La EC se caracteriza por una amplia variabilidad de manifestaciones clínicas, pero su forma clásica es la más habitual en el adulto; aquí los síntomas guía son de naturaleza gastrointestinal (diarrea, esteatorrea y dolor abdominal inespecífico). Por otro lado, las formas no clásicas y silentes son cada vez más frecuentes y se caracterizan por un amplio abanico de signos y síntomas como osteoporosis, hipovitaminosis D, anemia ferropénica, dermatitis herpetiforme, ataxia, polineuropatía sensitiva periférica, migrañas y alteración de las pruebas de función hepática (2).

Celiac disease, or gluten-sensitive enteropathy, is an immune-mediated disease of the small bowel that results in malabsorption. It classically presents with gastrointestinal symptoms including chronic diarrhea, weight loss, abdominal bloating and anorexia. It is becoming more frequently identified in asymptomatic patients with a diagnosis of deficiencies related to malabsorption of iron, folic acid, vitamin B12and vitamin D. It is increasingly identified as a cause for early or refractory osteoporosis. Occasionally, celiac disease presents with cutaneous manifestations alone. Dermatitis herpetiformis is a well-recognized cutaneous manifestation of celiac disease. Other cutaneous manifestations include alopecia, angular stomatitis and aphthous ulcerations. Described here is a case of a 24-year-old woman who presented with intermittent urticaria and gastrointestinal complaints. She was found to have celiac disease on small-bowel biopsy. Both her gastrointestinal symptoms and urticaria resolved when she was put on a gluten-free diet, suggesting that her urticaria was a cutaneous manifestation of celiac disease.

Dermatitis herpetiformis (DH) and bullous pemphigoid (BP) are skin diseases associated with eosinophilic and neutrophilic infiltrations. Although chemokines are critical for the selective accumulation and activation of various leukocyte subsets in the inflammatory process, there are few findings concerning inflammatory cells and production of coagulation factors in blistering diseases. Skin biopsies were taken from 14 patients with DH, 27 with BP, and 20 control subjects. The localization and expression of tissue factor (TF) in skin lesions and perilesional skin were studied by immunohistochemistry and confirmed by Western Blot. Moreover the plasma concentrations of TF were measured by immunoassays. D dimers, fibrinogen, and selected coagulation parameters were measured by routine methods. Expression of TF in the epidermis and in inflammatory influxed cells in dermis was detected in skin biopsies from BP patients. Examined TF expression was detected in perilesional skin of all BP patients too. The expression of TF was not observed in biopsies from healthy people and DH patients. The findings of the study show an increased expression of tissue factor in the lesional and perilesional skin of patients with bullous pemphigoid. The difference in chemokine pattern expression and variations in the cellular infiltration in BP and DH cause variable expression of TF.

Os pênfigos são dermatoses bolhosas autoimunes, em que há a produção de autoanticorpos direcionados contra moléculas de adesão dos epitélios, levando à perda da coesão celular. As doenças bolhosas intraepidérmicas são compostas pelo grupo dos pênfigos: pênfigo foliáceo clássico, pênfigo foliáceo endêmico, pênfigo eritematoso, pênfigo vulgar, pênfigo vegetante, pênfigo herpetiforme (variante clínica dos pênfigos vulgar e foliáceo), pênfigo por IgA, pênfigo paraneoplásico e pênfigo induzido por medicamentos. Devido à transferência placentária dos anticorpos IgG, existem casos de recém-nascidos com diagnóstico de Pênfigo Neonatal. Este artigo relata o caso de uma paciente recém-nascida de mãe com diagnóstico prévio de Pênfigo Vulgar com lesões exulceradas extensas na região perineal, couro cabeludo, cervical posterior e dorso, e também lesões bolhosas nos pés.Descritores: Pênfigo; Recém-Nascido; Dermatopatias; Doenças Autoimunes.ReferênciasSmolinski KN, Shah SS, Honig PJ, Yan AC.

Abstract Background and Aims Pemphigus is a potentially life-threatening autoimmune bullous disorder. The pathogenesis involves with IgG antibodies against desmogleins (Dsg) (Dsg 1 and Dsg 3) on epithelial cell surface. Systemic corticosteroid is considered as the basis of the treatment for pemphigus. As an interventional treatment, plasmapheresis was introduced for treating severe or refractory pemphigus. The literature in this field is limited. This study aimed to review our 10 years’ experience in a single center. Method We retrospectively analyzed 17 patients with severe pemphigus who were unresponsive to high-dose prednisone and received double-filtration plasmapheresis (DFPP) treatment between January 2010 and January 2020. The information on demographic characteristics, clinical and laboratory data, treatment regimens, and clinical outcomes were collected. Results 1. Clinical characteristics: Among 17 patients, 11 patients had pemphigus vulgaris (PV), 3 patients had pemphigus foliaceus (PF), 2 patients had paraneoplastic pemphigus (PNP) and 1 patient had pemphigus herpetiform (PH). The mean age of patients was 47.8±10.0 years; 8 male patients and 9 female patients. All seventeen patients were suffering from severe pemphigus and had a period of at least one week of high-dose prednisone (1∼1.5mg/kg/d), but they were unresponsive to corticosteroid and immunosuppressants treatment. 2. As an adjuvant therapy, they received DFPP treatment with 1 to 4 sessions for each patient. Most of the patients (7 patients) received 2 sessions every other day, 5 patients received 3 sessions, 4 patients just received 1 session and only one patient received 4 sessions. For each session, the exchange volume was 1∼1.5 plasma equivalent. After DFPP treatment, the titers of Dsg antibodies significantly decreased (p<0.001, Figure 1), Nikolsky’s sign became negative and no new blisters appeared. The erosions showed reepithelialization and started healing gradually. The dosage of corticosteroid could begin to taper down rapidly in 1 to 2 weeks. On discharge, the dosage of prednisone was 0.8-1mg/kg/d. 3. As to adverse events, 4 patients had transient hypotension during the procedure, but they could recover spontaneously after parameter adjustment. No major adverse events happened. Conclusion Plasmapheresis is an effective and relatively safe treatment for severe pemphigus. Plasmapheresis can also contribute to the dosage reduction of steroid to avoid more drug-related side effect.

We describe a case of vancomycin-induced linear IgA bullous dermatosis (LABD) with unusual features in a 75-year old woman who received intravenous vancomycin for methicillin-resistant Staphylococcus Aureus infection. Our patient demonstrated an unusual lesional distribution with initial facial involvement and a longer latent period than usual, which to our knowledge has not yet been reported in the literature. A skin punch biopsy including direct immunofluorescence study (IMF) confirmed the diagnosis of LABD. The patient’s cutaneous eruptions resolved over the next 14 days with stoppage of medication and supportive care without the need for systemic steroids. Physicians should be aware of this rare type of autoantibody mediated drug reaction in patients put on vancomycin. Early diagnosis using a skin punch biopsy with direct IMF study would avoid unnecessary laboratory investigations and initiate prompt management.RésuméNous décrivons ici un cas de dermatose bulleuse à IgA linéaire (DIgAL) d’origine médicamenteuse et aux caractéristiques inhabituelles, chez une femme âgée de 75 ans ayant reçu de la vancomycine par voie intraveineuse pour traiter une infection causée par un Staphylococcus Aureus résistant à la méthicilline. La patiente présentait une distribution inhabituelle des lésions avec une atteinte initiale à la face et une période de latence plus longue que la normale. À notre connaissance, cela n’a jamais été rapporté dans la littérature. Une biopsie à l’emporte-pièce de la peau, doublée d’un test d’immunofluorescence directe, a confirmé le diagnostic de DIgAL. Les lésions cutanées de la patiente se sont résorbées dans les quatorze jours suivant l’arrêt du médicament, avec des soins de soutien et sans recours à des stéroïdes systémiques. Il est important que les médecins soient informés de ce type rare de réaction médicamenteuse à médiation d’autoanticorps chez les patients sous vancomycine. Un diagnostic précoce par biopsie à l’emporte-pièce et test d’immunofluorescence directe permet d’éviter des examens de laboratoire superflus et de débuter une prise en charge rapide.Case SynopsisA 75-year-old woman presented to the emergency department with an altered level of consciousness and sepsis requiring intubation. She had been treated with Keflex for a wound infection post L5-S1 lumbar discectomy and fusion surgery, but now presented with an epidural abscess and ventriculitis confirmed to be due to methicillin-resistant Staphylococcus Aureus bacteremia. The patient was taking naproxen, baclofen, levothyroxine, fenofibrate, omeprazole, sotalol, hydrochlorothiazide, ativan, zopiclone, and acetaminophen. The patient was started on vancomycin just prior to duraplasty with incision and drainage. 27 days later, she developed a morbilliform maculopapular cutaneous eruption, which started on her face before progressing diffusely to the trunk and limbs (Figure 1A). The lesions were pruritic and urticarial with blanchable, erythematous, well-demarcated plaques containing some fine scale (Figure 1B). Blistering began ten days after presentation of the eruption resulting in erosion (Figure 1C and Figure 1D). There was no mucous membrane involvement or fever present.A BCD Figure 1. (A) Initial presentation of malar erythema on face. (B) Eruption involving extremities with a maculopapular (morbilliform) appearance. (C&D) Blistering began ten days after initial presentation of eruption. Investigations were unremarkable except for an elevated eosinophil level of 2.6 × 109/L and mild leukocytosis of 11.2 × 109/L. Peak serum vancomycin was found to be within therapeutic range at 21.2 μmol/L. A drug rash with eosinophilia and systemic symptoms (DRESS) syndrome was originally suspected; however, the patient had no fever nor any systemic symptoms making this diagnosis unlikely. A punch biopsy of skin lesion was performed for definitive diagnosis. Vancomycin was discontinued and changed to linezolid and the patient received intravenous fluids and topical steroids (betamethasone valerate 0.05% with 0.25% camphor and 0.25% menthol to affected areas of the body and valerate 2% to lesions on the face) to treat the eruption. The patient’s cutaneous eruptions resolved over the next 14 days with additional supportive care, which included pain control, fluid and electrolyte management and nutritional support without the need for systemic steroids.Histologic examination of the diagnostic skin punch biopsy showed a subepidermal blister with abundant inflammatory infiltrate in the dermis composed of numerous neutrophils, a few eosinophils and lymphocytes. The blister contained fibrin, neutrophils and eosinophils (Figure 2A and Figure 2B). Punch biopsy of peri-lesional skin for direct immunofluorescence (DIF) study showed IgA deposition in a linear fashion along the basement membrane zone (Figure 2C) confirming the diagnosis of LABD.ABC Figure 2. (A) Hematoxylin and eosin (H & E) stain of punch biopsy skin back shows a subepidermal blister (star) (B) Higher magnification showing abundant neutrophils (arrow, H&E stain). (C) Direct immunofluorescence (IMF) test on the perilesional skin shows linear IgA deposition along the basement membrane zone (arrow). DiscussionLinear immunoglobulin A (IgA) bullous dermatosis (LABD) is an acquired autoimmune subepidermal blistering disease of the skin and/or mucous membranes, which is defined by the histopathological finding of subepidermal vesicles with predominantly neutrophilic infiltration and linear IgA deposits in the basement membrane zone. This disease can occur in idiopathic and drug-induced forms. While the idiopathic form is more often seen in children and has been associated with specific HLA haplotypes, drug-induced LABD occurs predominantly in adulthood. 1,2 Drug-induced LABD has been reported with many drugs, including amiodarone, ampicillin, captopril, cefamandole, cyclosporine, diclofenac, glibenclamide, INF-gamma, IL-2, lithium, penicillin G, phenytoin, piroxicam, somatostatin, trimethoprim, vigabatrin, NSAIDs and acetaminophen.3,4 However, it has been most consistently associated with intravenous administration of vancomycin, which is responsible for approximately half the cases in the literature,5 and does not appear to be dose dependent.3 Although our patient was taking other medications that can precipitate LABD (NSAIDs and acetaminophen), the onset and time course of the disease strongly suggest that vancomycin is the causative agent.Vancomycin is known to produce a diverse variety of adverse drug reactions including the red man syndrome, which is an infusion-related reaction peculiar to vancomycin. Non- bullous maculopapular rash is the most frequent type of skin eruption, a hypersensitivity reaction. Systemic involvement causing DRESS syndrome has been rarely reported. Severe drug reactions such as leukocytoclastic vasculitis, extensive fixed drug eruptions (which are localized), Stevens-Johnson syndrome, toxic epidermal necrolysis and LABD are very rare.Vancomycin-induced LABD is a subepidermal blistering eruption, which is classically characterized by the appearance of many pruritic tense bullae on a base of annular erythema. However, the presentation can clinically mimic a variety of other vesiculobullous diseases, including patterns resembling dermatitis herpetiformis, bullous pemphigoid, erythema multiforme, and even more severe disorders like Stevens-Johnson syndrome and toxic epidermal necrolysis which makes the diagnosis difficult. 6 The histologic differential diagnoses for subepidermal blistering disease include bullous pemphigoid and dermatitis herpetiformis. Although there is histologic overlap between these conditions, predominance of neutrophils in the infiltrate and the classic IMF pattern of linear deposition of IgA along the basement membrane zone confirmed the diagnosis of LABD in our patient.Our patient presented with some unique clinical features worth mentioning. Firstly, cases of vancomycin-induced LABD in the literature are varied, but lesions have been reported to appear within 1–3 weeks of vancomycin administration.1,3,7 This is in contrast to the latency period of this case, where our patient’s lesions erupted almost one month after vancomycin administration. Additionally, cases in literature have most commonly reported cutaneous involvement affecting the limbs and trunk with sparing usually of the face and neck.1,8,9 However, our patient presented with a malar type eruption on the face at the initial presentation before spreading to the extremities. The variability in the presentation (latency period, lesional morphology, distribution) is important for clinicians to recognize so vancomycin-induced LABD is kept in the differential diagnosis and confirmatory skin biopsies are performed without delay. The variability of vancomycin-induced LABD may reflect the pathophysiology of the disease, which has still not been fully elucidated. Like other drug-induced immune conditions, it is possible the vancomycin cross-reacts with a component of the epidermal basement membrane, exposes sequestered antigens or alters the confirmation of epitopes resulting in the formation of autoantibodies.10 While the target antigens in idiopathic LABD have been extensively investigated, there are few reports of the causative target antigens in the drug-induced form.2 Reported basement membrane zone (BMZ) antigens include a 97 KDa protein (which may be identical to the extracellular portion of BPAg2), a 230 KDa protein (similar to BPAg1), BP180, LAD285, unidentified 210 KDa, 130 KDa and 83 KDa antigens.2,4,5,7,11 Most recently, IgA antibodies to the 145- and 165-kDa a3 subunits of laminin-332 have been reported in a case of vancomycin-induced LABD.12 The fact IgA autoantibodies have been reported to react with numerous BMZ antigens may explain why the disease presentation is so heterogeneous. Other laboratory investigations also underscore the variable and unpredictable manifestations of this drug-induced cutaneous disease because in addition to linear IgA deposition along the BMZ, patients may also have deposition of C3, IgG and circulating IgG and IgA autoantibodies (none of which were seen in our patient). 8,9A careful drug history is extremely important as immunohistopathological and clinical features are identical between drug-induced and idiopathic forms, yet prognosis and treatment are quite different.1 The prognosis of drug-induced LABD is usually favourable as patients experience remission with drug withdrawal, while spontaneous remission in the idiopathic form is 10–50%.7 Idiopathic LABD usually requires dapsone and if needed topical or oral steroid treatment, but its course may be protracted.13In conclusion, we report a case of vancomycin-induced LABD, which presented with a few unique clinical features that to the authors’ best knowledge have not been previously reported in the literature. Specifically, our patient’s morbilliform eruption started almost one month after the initiation of vancomycin and began on the face before spreading to the extremities. Prompt histological evaluation with IMF study allows precise diagnosis of this condition. This case report highlights the importance of keeping LABD in the differential diagnosis of vancomycin-induced blistering drug reactions which would prompt clinicians to perform a diagnostic skin biopsy, make a rapid diagnosis, initiate appropriate treatment and avoid unnecessary delay and investigations.DisclosureThe authors have no conflicts of interest.Ethics approval is not required for this type of research at our institution.References1.
