Pemphigus and pregnancy. Analysis and summary of case reports over 49 years

Neonatal pemphigus vulgaris

A neonate presented to a tertiary clinic with blisters and erosions over his trunk and extremities. The mother had multiple erosions with crusts affecting the scalp, oral cavity and trunk present since the first trimester and worse since delivery. Skin biopsy for histopathology and direct immunofluorescence confirmed pemphigus vulgaris (PV) in the mother. Indirect immunofluorescence assays for serum antibodies against desmogleins 1 and 3 were positive in both mother and baby confirming a diagnosis of neonatal PV. The baby's lesions healed spontaneously within 2 weeks, and the mother was clear at 2 months following treatment with rituximab.

Pemphigus and Pregnancy

Pemphigus in pregnancy is a special clinical scenario that has potential consequences on both maternal and fetal outcomes. Being an autoimmune disease with Th2 preponderance, pemphigus is expected to flare in pregnancy, especially in the first two trimesters. Fetal outcomes like stillbirth and neonatal pemphigus have been reported, the latter being a consequence of a transient transplacental transfer of autoantibodies. Management needs to be individualized keeping the risk/benefit ratios of therapies in mind while optimizing maternal and fetal health. It is crucial to have appropriate counseling regarding conception for women with pemphigus in the child-bearing period because the probability of adverse materno-fetal outcomes is higher if the disease is severe.

Pregnancy in pemphigus vulgaris: A systematic review

PROBLEM

Pemphigus vulgaris may worsen during pregnancy, leading to both maternal and fetal complications. The relationship between pemphigus vulgaris and pregnancy remains unclear, and the outcomes and treatments of pemphigus vulgaris during pregnancy have not been extensively discussed.

METHOD OF STUDY

This article systematically reviews the literature, focusing on the relationship between pemphigus vulgaris and pregnancy. We conducted comprehensive searches in PubMed, Embase, Cochrane Library, and Web of Science databases, identifying 42 studies reporting the disease course, pregnancy outcomes, and management of both pregnancy and pemphigus vulgaris.

RESULTS

A total of 57 cases were included in the analysis, categorized into three distinct forms: pemphigus vulgaris onset before pregnancy (n = 33), onset during pregnancy (n = 20), and onset during the postpartum period (n = 4). Fifty four cases reported treatment strategies, among them, 44 cases (81.5%) initially received systemic corticosteroid therapy during pregnancy. Out of these cases, 7 (15.9%) did not achieve successful remission and required alternative treatment approaches. In terms of pregnancy outcomes, 23 out of 62 neonates (37.1%) exhibited skin lesions or tested positive for anti-dsg IgG in their serum, while 16 neonates (25.8%) experienced other complications.

CONCLUSIONS

These findings highlight the importance of effectively managing pemphigus vulgaris during pregnancy to ensure optimal outcomes.

Pemphigus vulgaris in a neonate born to a mother with pemphigus vulgaris: A case report

Key Clinical Message

Active pemphigus vulgaris in the mother can lead to neonatal pemphigus vulgaris, which is usually self-limiting. Systemic corticosteroids are the mainstay of managing PV during pregnancy and until the child is breastfed.

Abstract

Pemphigus vulgaris (PV) is a potentially life-threatening autoimmune disease characterized by bullae and erosions over the skin and mucous membrane. PV is rarely reported in pregnant women and neonates. We reported the case of a 28-year-old Gravida 2 Parity 2 Living 1 who developed painful blisters and erosions in the oral cavity during third trimester of pregnancy. However, the diagnosis was delayed due to late presentation. The patient presented to our hospital at 37 weeks gestation with bullae and erosions distributed all over the body. Based on clinical evaluation and histopathology reports, she was diagnosed with PV. She delivered a child via cesarean section. The child also had similar lesions and was diagnosed with neonatal PV. Maternal PV was managed with prednisolone followed by azathioprine, leading to complete remission. No active intervention was required for neonatal PV as the condition was self-limiting.

Updates on the dermatopathology of pregnancy-associated skin conditions

Pathologists provide valuable input in the dermatological care of pregnant patients in various contexts. This article provides dermatopathology updates on cutaneous changes associated with pregnancy, organized based on the following classification system: physiological skin changes in pregnancy, specific dermatoses of pregnancy, dermatoses modified in pregnancy, and skin neoplasms in pregnancy. Awareness of the impact of pregnancy on the skin by pathologists is important, as this is an opportunity to contribute to diagnostic precision in this patient population.

Staphylococcal Scalded Skin Syndrome in Neonates: Case Series and Overview of Outbreaks

Skin and soft tissue infections caused by Staphylococcus aureus (S. aureus) cover a wide spectrum of diseases in neonates, including staphylococcal scalded skin syndrome (SSSS). We describe a representative case of SSSS in neonatal twins, which despite recurrence showed a mild clinical disease course. This case was part of a small outbreak on a neonatal intensive care unit and therefore exemplifies the existence of neonatal outbreaks with skin and soft tissue infections by S. aureus. Diagnosis is generally based on the clinical picture and response to antibiotics, but can be aided by histology and cultures. Sequence-based molecular techniques are available to evaluate typing and virulence of S. aureus in outbreak or surveillance settings. The pillars of treatment are antibiotics and supportive care. Methicillin resistance remains a topic of concern, especially in outbreak settings. Our overview of numerous outbreaks of neonatal S. aureus skin infections underlines the importance of outbreak management strategies, including screening to identify the source of the outbreak, and limiting exposure through hygienic measures and establishment of physical boundaries.

Burden of pemphigus vulgaris with a particular focus on women: A review

Pemphigus vulgaris is a chronic autoimmune mucocutaneous blistering disorder. Apart from the disease itself, other aspects of patients' life, including psychological, social, and financial, can be affected. Women are particularly more disposed to the impact of the disease due to their physiological characteristics, the specific periods of pregnancy and lactation as well as their social and familial role. In this review, we summarized the burden of pemphigus vulgaris on various aspects of women's lives. It is essential to understand these problems and provide appropriate support for patients with such a burdensome disease.

Diagnosis, fetal risk and treatment of pemphigoid gestationis in pregnancy: A case report

BACKGROUND

Pemphigoid gestationis (PG) is a rare autoimmune blistering disease that usually presents in the second or third trimester, with an incidence of 1 per 50000 pregnancies. PG tends to recur with an earlier onset and a more severe course in subsequent pregnancies. Skin biopsy markers can be confirmed by direct immunofluorescence staining.

CASE SUMMARY

Our patient was diagnosed with PG at 8 mo of gestation with fresh bullous lesion marks on the abdomen and limbs. Termination of the pregnancy was performed by cesarean section at 37 + 4 wk of gestation. The patient delivered an infant weighing 3620 gm. The infant had urticaria-like and vesicular skin lesions and was diagnosed with PG. The patient was discharged on prednisolone and in a satisfactory condition. The infant was discharged after anti-inflammatory therapy for one week.

CONCLUSION

PG is a rarely reported disease, and 10% of newborns develop mild clinical symptoms consisting of urticaria-like or vesicular skin lesions. We intend to remind clinicians to consider this condition when a patient presents with such lesions so that treatment can be started early and neonatal morbidity can be taken into account.

Current status and prospects for the diagnosis of pemphigus vulgaris

Introduction: Pemphigus vulgaris (PV) is an intraepidermal autoimmune bullous disease (AIBD) characterized by autoantibodies against desmosomal adhesion proteins, most commonly desmoglein (Dsg)3, leading to the suprabasal cleft formation and acantholysis.Areas covered: Direct immunofluorescence (DIF) and indirect immunofluorescence (IIF) studies display the intercellular deposition of IgG/C3 throughout the epidermis and presence of circulating autoantibodies respectively, as a net-like pattern. However, the target antigen remains unknown using immunofluorescence techniques. Thanks to the development of Dsg ELISA, using recombinant technology, circulating antibodies against Dsg1 and 3 could be detected sensitively. It is possible to differentiate PV from pemphigus foliaceus (PF) using this assay. BIOCHIP mosaic and multivariant ELISA are two novel serologic methods with the added value of the ability to screen several AIBDs simultaneously.Non-Dsg1/3 antigens are also involved in the pathogenesis of PV and investigated more deeply thanks to the protein microarrays technique. Additionally, patients with high values of anti-Dsg1/3 may be lesion-free, suggesting the presence of nonpathogenic autoantibodies.Expert opinion: Newer diagnostic methods to replace traditional techniques should possess high sensitivity and specificity and be widely available, noninvasive, and relatively cheap. The newly developed methods need to be further evaluated before being recommended for routine use.

Recurrent Pregnancy Induced Pemphigus Vulgaris: A Rare Case Report

Pemphigus vulgaris is a potentially life-threatening bullous autoimmune disease that can be triggered by various factors, one of which is pregnancy. Cases of pregnancy induced pemphigus are rare, and can result in devastating outcomes, both from the maternal or fetal perspectives if not treated promptly and adequately. The use of systemic corticosteroids is paramount to improve the outcome of the patient and fetus and it is a first-line treatment for the disease. Patients with a history of pemphigus should plan their pregnancies carefully, taking into consideration a minimum of 6 months remission before conception. This case report is about a 28-year-old woman with a history of pemphigus vulgaris that did not seek medical treatment of her pemphigus, which resulted in the intrauterine fetal death. The patient was treated with systemic corticosteroids and achieved great resolution to her blisters and overall wellbeing.

Treatment of Autoimmune Bullous Diseases During Pregnancy and Lactation: A Review Focusing on Pemphigus and Pemphigoid Gestationis

Pregnancy may induce the onset or exacerbation of autoimmune bullous diseases such as pemphigus or pemphigoid gestationis. A shift toward T helper (Th) 2 immune response and the influence of hormonal changes have been evoked as possible triggering factors. Therapeutic management of this setting of patients may represent a challenge, mainly due to safety concerns of some immunosuppressive drugs during pregnancy and lactation. In this narrative review, we provided a comprehensive overview of the therapeutic management of autoimmune bullous diseases in pregnant and breastfeeding women, focusing on pemphigus and pemphigoid gestationis.

The Influence of Pregnancy on the Clinical Evolution and Prognosis of Pre-Existing Inflammatory and Autoimmune Skin Disorders and Their Management

BACKGROUND

Although the possible occurrence of typical dermatoses during pregnancy is well recognized, little is known about the influence of pregnancy on the clinical evolution and prognosis of different pre-existing chronic dermatological disorders.

SUMMARY

In this study a comprehensive search of the available literature and reviews has been undertaken in order to collect and analyze articles reporting pre-existing chronic skin disorders in pregnant women and report current knowledge on their particular clinical and therapeutic aspects.

Neonatal Pemphigus Vulgaris: A Case Report

: Pemphigus vulgaris (PV) is an autoimmune blistering disorder of the skin and mucous membranes. The transplacental passage of maternal immunoglobulin G (IgG) autoantibodies to desmoglein-3 (a transmembrane glycoprotein component in the skin) from the mother’s blood to the fetus can cause transient PV in the neonatal period. The duration of PV is short in the neonatal period, and the disease is improved with no prolonged sequelae. The similarity of skin lesions in PV to other skin conditions, such as infectious diseases caused by bacterial, viral, and fungal pathogens, or inherited bullous disorders, such as epidermolysis bullosa and incontinentia pigmenti, leads to misdiagnosis, inappropriate hospital admission, and poor antimicrobial treatment of patients. On the other hand, the maternal history of PV, besides laboratory examination, confirms the exact diagnosis. In this case report, we present a male term neonate with multiple pustules and blisters on the skin, developed within the first hours of life. The patient was admitted to the neonatal ward of our hospital for a sepsis workup and antibiotic treatment. Regarding the positive maternal history of PV in the second trimester of pregnancy and neonatal examinations skin biopsy confirmed the diagnosis of this disease.

Autoimmune bullous diseases during pregnancy: Solving common and uncommon issues

Autoimmune bullous diseases during pregnancy pose a therapeutic challenge for medical dermatologists. There are main concerns with regard to the regimen, dose, route of administration, and potential harm to the fetus. Many therapeutic options may be safe during pregnancy despite official classifications. Furthermore, there are always questions regarding management during the lactation period. Additionally, issues exist about male and female fertility and the time of discontinuation of certain medications before conception. In this article, we present an overview of the literature based on answers to these issues to solve common and uncommon management problems that arise about a spectrum of autoimmune bullous diseases before conception, as well as during pregnancy and the lactation period.

Management of autoimmune blistering diseases in pregnancy and the neonate

The management of autoimmune blistering diseases (AIBD) is therapeutically challenging, particularly in patients who plan to conceive, or are pregnant or breastfeeding. Not only is a patient's immune system altered by pregnancy-associated hormonal changes, but several medications used for AIBD treatment are not recommended for use in pregnancy or lactation. The data acquired regarding the safety and efficacy of these therapeutic interventions are gathered from studies or case reports from other diseases, as the treatment modalities are similar and randomized controlled trials are typically not performed in the setting of pregnancy. Although some medications for AIBD treatment are considered unsafe for use in pregnancy, many effective and tolerable therapies are able to provide benefit to these patients. In fact, most first-line agents may be used in pregnancy, to a given extent. This article discusses the medications used to treat AIBD prior to conception, during pregnancy, and while breastfeeding, as well as highlights those that are contraindicated. The preferred approach to management in these patients is also discussed. Additionally, we present the available information regarding neonates of mothers with a diagnosis of AIBD, including the likelihood, identification, and management of neonatal blistering and the effects from medication exposure in utero.

Consensus on the treatment of autoimmune bullous dermatoses: pemphigus vulgaris and pemphigus foliaceus - Brazilian Society of Dermatology

Pemphigus are intraepidermal autoimmune bullous dermatoses that occur with lesions on the skin and / or mucous membranes. The most frequent types are pemphigus vulgaris and pemphigus foliaceus (classic and endemic). This consensus aims to present a complete and updated review of the treatment of these two more frequent forms of pemphigus, based on the literature and the personal experience of the authors. In moderate and severe cases of pemphigus vulgaris and foliaceus, systemic corticosteroid therapy (prednisone or prednisolone) is the treatment of choice. Adjuvant drugs, usually immunosuppressive drugs (azathioprine, mycophenolate mofetil, methotrexate, cyclophosphamide) may be prescribed as corticosteroid sparers in refractory cases or with contraindications to corticosteroids to minimize side effects. In severe and nonresponsive cases, corticosteroids in the form of intravenous pulse therapy, immunoglobulin and plasmapheresis / immunoadsorption can be administered. Immunobiological drugs, particularly rituximab, appear as a promising alternative. For milder cases, smaller doses of oral corticosteroid, dapsone and topical corticosteroids are options. At the end flowcharts are presented as suggestions for a therapeutic approach for patients with pemphigus vulgaris and pemphigus foliaceus.

Autoimmune bullous diseases during pregnancy: insight into pathogenetic mechanisms and clinical features

Pemphigoid gestationis (PG), also known as herpes gestationis, is the prototypic pregnancy-associated autoimmune bullous disease (AIBD), but also the other AIBDs, notably pemphigus vulgaris, may begin or exacerbate during pregnancy. Although the increase in concentration of T and B regulatory cells makes pregnancy a state of increased immunologic tolerance toward the semiallogeneic fetal antigens, a prevalent T helper (Th) 2 profile, that is reported to be associated with pregnancy, may cause exacerbation of pemphigus and AIBDs in general during this period. Active disease may lead to stillbirth, spontaneous abortion, preterm pregnancy, low birthweight, and neonatal pemphigus. PG is a rare AIBD usually starting during the third trimester of pregnancy and healing in the postpartum. It is due to the formation of autoantibodies directed against different epitopes of bullous pemphigoid (BP) 180 as a consequence of the aberrant expression of BP180 in the placental tissue of genetically predisposed women. PG is characterized by vesicles with herpetiform distribution, blisters and urticarial elements typically involving the periumbilical area and the distal portion of the upper limbs. Diagnosis is based on: 1) physical examination; 2) histopathological pattern consisting of a dermal inflammatory infiltrate rich in eosinophils; 3) direct immunofluorescence test demonstrating linear deposits of complement fraction 3 and immunoglobulin G along the basement membrane zone; 4) detection of circulating autoantibodies by means of indirect immunofluorescence or enzyme linked immunosorbent assay. Here, we provide an updated overview on the pathophysiologic mechanisms of pregnancy-associated or pregnancy-exacerbated AIBDs, focusing also on peculiar clinical features of these disorders.

New onset pemphigus foliaceus during pregnancy: A rare case

Pemphigus is a rare autoimmune disease during pregnancy. Among the different pemphigus types, pemphigus foliaceus (PF) is even rarer than pemphigus vulgaris. We present a case of PF in a 36-year-old female patient who presented with PF onset during pregnancy in the form of a disseminated, erythematosquamous rash. A diagnosis was made on the basis of histologic, immunofluorescence, and enzyme-linked immunosorbent assay results. A complete remission was recorded a month after steroid treatment initiation. The patient delivered a premature (33 weeks) but otherwise healthy baby girl. Only three cases of PF have been reported in two retrospective studies found in the English-language bibliography. Although pemphigus during pregnancy is a rare disease and treatment guidelines have not yet been elucidated, the management of these cases is individually evaluated. In all cases, the primary goal should be the control of the maternal disease along with the safety of the fetus.

AUTOIMMUNE BULLOUS DERMATOSES. DIFFERENTIAL DIAGNOSIS

The review presents modern ideas concerning autoimmune bullous dermatoses (pemphigoid group): Duhring disease, bullous pemphigoid, cicatrizing pemphigus, pemphigoid gestationis, linear IgA bullous dermatosis and acquired bullous epidermolysis. Pathogenesis, clinical manifestations and modern methods of disease diagnostics are reported. Particular attention is paid to the diagnosis of acquired bullous epidermolysis, in which the leading role belongs to the reaction of immunofluorescence. The pathogenetic similarity between bullous pemphigoid, linear IgA dermatosis, cicatrizing pemphigoid and pemphigoid gestationis is shown, which allows us to regard them as a variety of a single pathological process.

Medical treatments for pregnant patients with oral lichen planus

Oral lichen planus (OLP) is a common chronic inflammatory disorder that manifests as papular, reticular, or erosive lesions. OLP seriously affects a patient's quality of life, as it is associated with symptoms such as pain and a burning sensation. It is also accompanied by a risk of carcinogenic tendency. During pregnancy, the treatment will be more complicated because of the effect of medical treatment on both the mother and foetus. Thus, appropriate drugs for those pregnant patients will be more essential. This study aimed to review the safety of drugs used for the treatment of OLP during pregnancy and to establish an appropriate treatment plan for pregnant patients with OLP.

Oral and vulvovaginal changes in pregnancy

Physiologic alterations of the oral and vulvovaginal mucosal surfaces result from the profound hormonal and immunologic changes of gestation. High estrogen levels are responsible for the vascular changes noted on mucosal surfaces. Gingival hyperemia and edema, gingivitis and pyogenic granuloma are the most common alterations of the oral mucosa during gestation. Physiologic changes of the vulvovaginal area are mainly of vascular nature, and include among others varicose veins. The oral and vulvovaginal mucosal surfaces can be affected by diseases that can worsen or develop in pregnancy. Oral lesions are encountered in a large spectrum of diseases including aphthosis, pemphigus vulgaris, systemic lupus, and Behçet disease. Pregnancy dermatoses such as impetigo herpetiformis and gestational pemphigoid can exceptionally affect the oral mucosa. Infections of the vulvovaginal region by Candida species, Trichomononas vaginalis, human papilloma virus, and herpes simplex virus have been associated with fetal risks. The dermatologist, obstetric medicine physician, and neonatologist should be familiar with the above physiologic changes as well as maternal/fetal risks relevant to disease affecting these mucosal surfaces during gestation.
