Dermatoses of pregnancy

Severe case of pustular psoriasis during pregnancy

Pustular psoriasis of pregnancy (PPP) is a rare variant of generalised pustular psoriasis occurring during or after pregnancy. PPP can have significant maternal and fetal morbidity if left untreated. In this case report, we present a pregnant woman with this rare cutaneous disorder and how it was treated. Due to the limited available evidence regarding the treatment of PPP, we describe the treatment that was given based on the clinical manifestations and severity of the disease.

Recognizing, Diagnosing, and Managing Pregnancy Dermatoses

Pregnancy dermatoses are inflammatory skin disorders that occur during pregnancy or immediately postpartum. This heterogenous group of disorders includes pemphigoid gestationis, polymorphic eruption of pregnancy, intrahepatic cholestasis of pregnancy, atopic eruption of pregnancy, and pustular psoriasis of pregnancy. In this article, we provide a comprehensive literature review of each condition focusing on nomenclature, epidemiology, pathogenesis, clinical presentation, diagnosis, differential diagnosis, maternal risk, fetal risk, and treatment. We aim to increase awareness and help clinicians recognize, diagnose, and manage these unique conditions.

Prevalence and Relevance of Pruritus in Pregnancy

Pregnant women are at greater risk to suffer from chronic pruritus, but data on this symptom in this group is very limited. The aim of this study was to investigate the prevalence, clinical characteristics, and the importance of pruritus in pregnant women. A total of 292 consecutive pregnant women at the 33.0 ± 6.1 weeks of gestation (WoG) were recruited into this prospective, cross-sectional study. All patients underwent thorough anamnesis and detailed physical examination with the special emphasis on pruritus. Pruritus was assessed according to Visual Analogue Scale (VAS). Quality of life was measured with the Dermatology Life Quality Index (DLQI). The point prevalence of pruritus was 20.2% (n = 59), while pruritus prevalence during the entire pregnancy was 38.0% (n = 111). Pruritus started on average at the 27.2 ± 7.6 WoG; it was significantly more common among women in third trimester. The mean VAS was 4.8 (±2.4) points. The DLQI scoring significantly correlated with VAS (r = 0.52, p < 0.001). Based on the results of our study about one-third of women suffer from pruritus during pregnancy. Many of them find it a very distressing and disturbing symptom.

[Pemphigoid gestationis and aplasia cutis congenita: report of a case]

La pemphigoïde gestationis est une dermatose gravidique apparaissant en général entre la 28^ème et la 32^ème semaine d'aménorrhée. L’éruption cutanée est prurigineuse, bulleuse ou vésiculopapuleuse et de topographie péri-ombilicale. Outre la clinique, son diagnostic repose sur la biopsie cutanée avec analyse en immunofluorescence directe. Elle se caractérise par sa tendance à récidiver. Le traitement habituel nécessite des dermocorticoïdes. Les conséquences peuvent être maternelles (menace d'accouchement prématuré), fœtales (retard de croissance intra-utérin), et néo-natales (éruption cutanée). Nous rapportons un cas de pemphigoïde gestationis associé à une aplasie cutanée congénitale type 2. S'agit il d'une association fortuite?

Specific dermatoses of pregnancy and their treatment

The specific dermatoses of pregnancy represent a diverse group of intensely pruritic dermatoses, occurring only in the puerperal state. The relative rarity of these conditions, the often variable clinical appearance, and the lack of definitive diagnostic tests have led to confusion regarding the appropriate diagnosis and management of the specific dermatoses of pregnancy. Herein we review the clinical characteristics, diagnosis and treatment of five dermatoses occurring during pregnancy: pruritic urticarial papules and plaques of pregnancy, atopic eruption of pregnancy, pemphigoid gestationis, intrahepatic cholestasis of pregnancy, and pustular psoriasis of pregnancy.

Intra-hepatic Cholestasis of Pregnancy: A Comprehensive Review

Intra-hepatic cholestasis of pregnancy is a cholestatic disorder characterized by i) pruritus, with onset in the third trimester of pregnancy, without any primary skin lesions, ii) elevated fasting serum bile acids > 10 μmol/L (and elevated serum transaminases), iii) spontaneous relief of signs and symptoms within two to three weeks after delivery, and iv) absence of other disease that cause pruritus and jaundice. It is believed to be a multi-factorial disease with interplay between genetic, environmental and hormonal factors. Incidence is between 0.02% to 2.4% of all pregnancies; with wide geographical variations. Maternal prognosis is usually good but can result in adverse fetal outcomes like meconium staining of amniotic fluid, fetal bradycardia and even fetal loss. Response to anti-histaminic is poor. Of all the medical therapies that have been described for the treatment for IHCP, ursodeoxycholic acid has the best response in relieving pruritus in mother, and probably has a role in preventing even the perinatal complications. Timely diagnosis and treatment is urged in order to prevent fetal complications and an early delivery between 37 to 38 weeks should be contemplated in severe cases, especially once fetal lung maturity is attained.

First trimester impetigo herpetiformis in multiparous female successfully treated with oral cyclosporine

Impetigo herpetiformis or gestational pustular psoriasis can account for 4.25% of all pregnancy dermatoses seen. Unlike other pregnancy dermatoses, it can be associated with constitutional symptoms including fever, rigors, arthralgia and complications of secondary infection and sepsis. There is an increased risk of fetal anomalies and stillbirths. A 25-year-old para 1 presented to primary care at 7 weeks gestation with a peri-umbilical rash non-responsive to topical steroids and underwent hospital admission at 31 weeks gestation with fever and a widespread painful erythematous rash. Her condition worsened despite high-dose oral steroids. With the use of cyclosporine and regular opioid analgesia over 2 weeks, her symptoms were adequately controlled. She went into spontaneous labour at 41(+2) weeks and delivered a healthy male infant. Impetigo herpetiformis can be treated first line with topical and oral steroids and supportive measures, but immunomodulatory therapies such as cyclosporine have shown success in treating resistant cases.

Pregnancy dermatoses: diagnosis, management, and controversies

Some aspects regarding the etiology and the nosologic classification of various pregnancy dermatoses are highly controversial. While some authors highlight the existence of premises allowing several skin disorders to be re-grouped within broader disease concepts, others underline the absence of clear, undisputed etiopathogenetic data that could support such classifications. This review exhaustively analyzes the various pregnancy dermatoses (pemphigoid gestationis, intrahepatic cholestasis of pregnancy, impetigo herpetiformis, polymorphic eruption of pregnancy, and the papular dermatoses of pregnancy [prurigo of pregnancy, pruritic folliculitis of pregnancy, and the new classification, atopic eruption of pregnancy]) in an attempt to shed light over this confusing and disputed domain, while subsequently offering an algorithmic approach to their diagnosis and management. While for pemphigus gestationis, intrahepatic cholestasis of pregnancy, and impetigo herpetiformis, specific diagnostic tests such as histopathology, immunofluorescence, or laboratory investigations will confirm the diagnosis, the identification of the other types of pregnancy dermatoses is based only on clinical criteria. In this context, the review argues for the inclusion of the whole group represented by the papular dermatoses of pregnancy within the broad spectrum of polymorphic eruption of pregnancy, separating each of these entities by focusing on their onset: early-onset polymorphic eruption of pregnancy (comprising prurigo of pregnancy, pruritic folliculitis of pregnancy, and atopic eruption of pregnancy) and late-onset polymorphic eruption of pregnancy. In light of the same practical approach guiding it, the review provides updated treatment strategies for each of these conditions.

Dermatologic Manifestations of the Hypereosinophilic Syndromes

Skin is a commonly affected organ in hypereosinophilic syndromes (HES). Cutaneous lesions may be an important presenting sign, may be extremely debilitating, and often reflect disease activity in HES. Recognition of dermatologic manifestations is important in approaching diagnosis and treatment of HES. This article reviews cutaneous involvement in HES and other eosinophil-associated skin diseases.

Impetigo herpetiformis

Impetigo herpetiformis is a rare pustular disorder that occurs primarily in pregnancy and is often associated with hypocalcemia. The onset commonly presents in the last trimester of pregnancy; the condition may persist until delivery and it rarely continues in the postpartum period. There is an increase in morbidity and mortality for the mother and the fetus. As a result, immediate diagnosis and treatment is crucial. The purpose of this article is to delineate the clinical picture of this disease, its treatment, and the effect on the mother and the fetus.

Pruritic urticarial papules and plaques of pregnancy: polymorphic eruption of pregnancy (PUPPP)

The most commonly diagnosed pruritic dermatosis of pregnancy has a confusing nomenclature. The most commonly term used in the United States is pruritic urticarial papules and plaques of pregnancy (PUPPP), and in Great Britain, since 1982, polymorphic eruption of pregnancy. The etiology of PUPPP is still unknown. Placental products, hormonal alterations, and damage to connective tissue with subsequent conversion of nonantigenic molecules to antigenic ones, have been proposed as possible causes. The maternal and fetal prognosis is excellent. Treatment consists of topical or oral corticosteroids. Delivery does not usually provide relief of symptoms.

Dermatologia e gestação

Neste estudo conduz-se uma revisão bibliográfica da literatura sobre dermatologia e gravidez abrangendo o período de 1962 a 2003. O banco de dados do Medline foi consultado com referência ao mesmo período. Não se incluiu a colestase intra-hepática da gravidez por não ser ela uma dermatose primária; contudo deve ser feito o diagnóstico diferencial entre suas manifestações na pele e as dermatoses específicas da gravidez. Este apanhado engloba as características clínicas e o prognóstico das alterações fisiológicas da pele durante a gravidez, as dermatoses influenciadas pela gravidez e as dermatoses específicas da gravidez. Ao final apresenta-se uma discussão sobre drogas e gravidez.

[Pemphigoid gestationis and vasculorenal syndrome: a fortuitous association?]

Pemphigoid gestationis is a gestational skin disease usually appearing between the 28th and the 32nd week of amenorrhea. It is a rare vesiculobullous skin disease and the eruption is located around the umbilicus. The diagnosis is made with clinical symptoms but mainly on histologic examination (after skin biopsy) and direct immunofluorescence. One of the main complications is the rate of recurrence. The main treatment is based on topical corticosteroids. The effects of the pemphigoid gestationis are maternal (preterm labor), fetal (intrauterine growth retardation) and neonatal (bullous disease). We report a case of pemphigoid gestationis associated to a gestational hypertensive disorder and we try to rely on both entities.

Specific dermatoses of pregnancy: an evidence-based systematic review

OBJECTIVE

We conducted an evidence-based systematic analysis of the literature on specific dermatoses of pregnancy.

STUDY DESIGN

The bibliographic databases MEDLINE and EMBASE were screened for studies and reports in all languages about herpes gestationis, pruritic urticarial papules and plaques of pregnancy, pruritic folliculitis of pregnancy, and prurigo of pregnancy from January 1962 to January 2002. As main index terms, including analogs and derivatives, we used the names of specific dermatoses of pregnancy. Intrahepatic cholestasis of pregnancy, not a primary dermatosis, was included herein because this disorder is associated with pregnancy and its secondary skin manifestations must be differentiated from specific dermatoses of pregnancy. Other sources were abstract books of symposia and congresses, theses, textbooks, monographs, reviews, editorials, letters to the editor, free or rapid communications, and the reference lists from all the articles that were retrieved. All articles selected for inclusion in this review were evaluated critically with regard to their impact factor and evidence-based contribution to this field, as measured by their citation index and impact factor of the journal in which they were published. Approximately 39% of articles met the selection criteria.

RESULTS

The clinical features and prognosis of the specific dermatoses of pregnancy have been delineated through a number of retrospective and cohort studies. The molecular biologic and immunogenetic properties of herpes gestationis, pruritic urticarial papules and plaques of pregnancy, and intrahepatic cholestasis of pregnancy have been further clarified. A meta-analysis in this review reveals a higher prevalence of multiple gestation pregnancy (11.7%) among patients with pruritic urticarial papules and plaques of pregnancy. Several investigations have unraveled the fetal complications in intrahepatic cholestasis of pregnancy and herpes gestationis. New treatment modalities in intrahepatic cholestasis of pregnancy (cholestyramine, ursodeoxycholic acid) and herpes gestationis (cyclosporin, intravenous immunoglobulin, and tetracyclines postpartum) have shown promise and warrant further evaluation.

CONCLUSION

During the past few decades, a significant amount of new data has provided new insights into the classification, pathogenesis, treatment, prognosis, and fetal risks that are associated with the specific dermatoses of pregnancy.

Dermatoses of pregnancy

The dermatoses of pregnancy can be classified into the following 3 groups: physiologic skin changes in pregnancy, dermatoses and cutaneous tumors affected by pregnancy, and specific dermatoses of pregnancy. Correct diagnosis and classification are essential for the treatment of these disorders, when necessary. Laboratory investigations are required when the diagnosis remains in question despite a careful history and thorough physical examination. A discussion with the pregnant woman about the nature of her skin condition, and the possible fetal risks associated with it, is imperative.

The specific dermatoses of pregnancy: a re-appraisal

Pregnancy is associated with immunological, endocrine, metabolic and vascular changes that may adversely affect the skin. The specific dermatoses of pregnancy are disease entities almost exclusively related to the pregnancy or the puerperium.

LEARNING OBJECTIVE

At the conclusion of this learning activity, participants should be aware of the main entities of the specific pregnancy dermatoses, their clinical presentations, the main diagnostic criteria and therapeutic options.

Common dermatoses of pregnancy

Awareness of pregnancy-related skin changes can facilitate improved care of women during pregnancy by identifying those skin changes that require further evaluation. Women experience significant endocrine and metabolic changes during pregnancy that can cause both physiologic and pathologic alterations in the skin, nails, and hair. This review discusses the physiologic changes and pruritic dermatoses that are specifically associated with pregnancy. The effect of pregnancy on preexisting skin diseases and safe treatment options for usage during pregnancy will be provided.

Pruritus gravidarum: a clinical and laboratory study

Five hundred pregnant women attending obstetrics OPD were screened for the presence of pruritus. The patients with other dermatological causes of pruritus (other than specific dermatosis of pregnancy) were excluded from the study. The selected patients were further subjected to routine laboratory investigations including liver function tests and IIBs Ag detection. The prevalence of pruritus in pregnancy was found to be 4.6% (23 cases). Ten patients were found to have specific dermatoses of pregnancy, including four cases of pruritus gravidarum and four of pruritic urticarial papules and papules of pregnancy. The prevalence of pruritus gravidarum was 0.8% of pregnancies. All the patients with pruritus gravidarum were primigravidae and had no clinical overlap with other specific dermatoses of pregnancy, jaundice, or intrahepatic cholestasis. One case of perinatal death was recorded among the pruritus gravidarum cases. This study has been helpful in determining the prevalence and severity of pruritus gravidarum in South India.

Eosinophilic vasculitis syndrome: recurrent cutaneous eosinophilic necrotizing vasculitis

We recently identified a syndrome of recurrent cutaneous eosinophilic vasculitis in three patients. These patients had in common widespread pruritic, erythematous, purpuric papules and angioedema of face and hands associated with peripheral blood eosinophilia. Eight skin biopsies from these three patients all showed necrotizing vasculitis of the small vessels of the skin, with exclusively eosinophilic infiltration and minimal or no leukocytoclasis. The disease followed a chronic course, with recurrent, itchy, swelling skin lesions and without evidence of systemic involvement over observation periods of 3, 17, and 23 years. The skin lesions responded promptly to systemic steroid treatment, but two patients required maintenance doses for control of the disease. Immunofluorescence studies showed marked deposition of the cytotoxic eosinophil granule major basic protein in the affected vessel walls. Eosinophil-active cytokine IL-5 was detected in the serum of one patient. Expression of the vascular cell adhesion molecule-1 for eosinophil adherence was detected on the endothelium of the affected vessels. Because this disease showed distinctive clinical manifestations and characteristic histopathological features, we believe it is a distinct entity and should be distinguished from other types of vasculitis.

A prospective immunofluorescence study of 111 cases of pruritic dermatoses of pregnancy: IgM anti-basement membrane zone antibodies as a novel finding

Since 1981, all pregnant women presenting to our department with a pruritic dermatosis have been investigated by histological and immunopathological techniques. We recruited 111 patients and performed skin histology in 77, 109 direct immunofluorescence tests (DIF), 74 indirect immunofluorescence tests (IIF) and 15 Western blots (WB). We identified: (i) five typical cases of pemphigoid gestationis (PG) (4.5%), corresponding to an incidence of 1/7000 pregnancies. (ii) Five cases without PG but showing circulating anti-BMZ antibodies of IgM type. With the exception of one case, clinical features were homogeneous--occurrence of erythematous papular and/or urticarial lesions on the trunk, and less often, on the limbs between the 32nd and 38th week of pregnancy. Rapid clearance of lesions within a few days was the rule. Whenever performed, DIF was negative and IIF showed circulating anti-BMZ antibodies of IgM type. Western blot studies were negative in these five cases. (iii) One hundred and one cases with negative immunofluorescence tests, considered to be suffering from polymorphic eruption of pregnancy. Our results show the value of systematic immunopathological investigations in pregnant women presenting with a pruritic dermatosis, and raise the possibility of a new entity, as defined by circulating anti-BMZ antibodies of IgM type.

Skin diseases aggravated by pregnancy

During pregnancy, immunologic, endocrine, metabolic, and vascular changes occur that make the pregnant woman susceptible to aggravation of certain skin diseases. These diseases can be organized into five broad categories: infections, diseases of altered immunity, metabolic diseases, connective tissue disorders, and miscellaneous conditions. A discussion of how each of these diseases is altered by pregnancy and how treatment may differ during gestation is presented.

Linear IgM dermatosis of pregnancy

An intensely pruritic dermatosis that occurred in a woman during the third trimester of pregnancy is described. The clinical manifestations included red follicular papules symmetrically distributed on the skin of the forearms, abdomen, thighs, and legs. The histopathologic findings were not specific. However, immunopathologic examination revealed dense linear deposition of IgM in the dermoepidermal junction. The eruption and the immunopathologic findings disappeared at the end of the puerperium. This dermatosis differs from previously described specific dermatoses of pregnancy because of the clinical appearance and the immunopathologic findings. Thus we propose the term linear IgM dermatosis of pregnancy.

Contact dermatitis in Nigeria (i). Hand dermatitis in women

Of 545 consecutive contact dermatitis clinic patients, 271 (49.7%) were women, 29 (10.7%) of whom had hand dermatitis alone. 17 (58.6%) of these hand cases were allergic, the main sensitizers being nickel and essential oils in oranges. Dress makers were mostly affected by nickel, while orange sellers and peelers were positive to orange peel, fragrance mix, balsam of Peru and formaldehyde in varying combinations. 8 (27.6%) of the hand cases were due to irritants and wet jobs, and possibly to allergens not tested. 24 (83%) of the hand cases were occupational. Only 1 Nigerian woman had true housewife's hand dermatitis. It was not possible to define the rôle of atopy because of unreliable histories. 2 cases of pompholyx and a negative patch test occurred in the first trimester of pregnancy.

Autoimmune progesterone dermatitis with persistent amenorrhoea

A case of autoimmune progesterone dermatitis is reported. The patient developed a recurrent eruption, primarily on the extremities, after receiving oral progesterone for the treatment of persistent amenorrhoea. Intradermal injection of 17 alpha-hydroxyprogesterone produced a positive skin reaction after 30 min, but no delayed onset reaction was observed. A patch test with progesterone in petrolatum was negative. The lymphocyte transformation test was normal. Histamine release from passively sensitized peripheral blood leukocytes was increased by progesterone preincubated in normal serum as a stimulating antigen. Conjugated oestrogen therapy suppressed the rash. Cyclical eruptions with elevated basal body temperature persisted for more than 20 months without menstruation.

Physiologic skin changes in pregnancy

Pregnancy produces many skin changes, some of which are specifically related to pregnancy (dermatoses of pregnancy) and others that are more common and called physiologic. These physiologic skin changes usually do not impair the health of the mother or the fetus; nevertheless, some can be cosmetically significant and of importance to the dermatologist.

Pregnancy's effects on the skin. Common and uncommon changes

The skin almost always shows changes during pregnancy. Some of these alterations are so predictable as to be considered normal. Not nearly so common are a host of pruritic dermatoses, including pruritus gravidarum, herpes gestationis, pruritic urticarial papules and plaques of pregnancy, Spangler 's papular dermatitis of pregnancy, and impetigo herpetiformis. Some of these conditions can cause maternal and/or fetal complications and even death; others, although benign and transient, add to the stress of pregnancy. Physician adeptness at diagnosing and treating skin diseases specific to or affected by pregnancy is thus of vital importance in caring for pregnant women.

Dermatoses of pregnancy

Pregnancy is a period of profound endocrine and metabolic changes which are tolerated by the body for a relatively short time. During gestation both physiologic and pathologic changes can occur in the skin, nails, and hair shafts which should be recognized and appropriately managed by the dermatologist. These changes can conveniently be placed into five broad categories: (1) physiologic changes in skin and appendages caused principally by the hormonal milieu, (2) cutaneous tumors affected by pregnancy, (3) diseases specifically associated with pregnancy, (4) genital infections of perinatal importance, and (5) other dermatologic diseases influenced by pregnancy. A discussion of each of these topics reveals the vast spectrum of dermatologic disease seen in pregnancy and underscores the important role of the dermatologist in the care of pregnant patients.
