Diagnosis and Therapy of Localized Scleroderma

JOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 2009
Alexander Kreuter
Abstract Localized scleroderma is a rare autoimmune disease with primary affection of the skin, and occasional involvement of the fat tissue, muscle, fascia, and bone. Depending on the clinical subtype, the spectrum of skin lesions ranges from singular plaque lesions to severe generalized or linear subtypes which may lead to movement restrictions and permanent disability. This German S1-guideline proposes a classification of localized scleroderma that, considering the extent and depth of fibrosis, distinguishes limited, generalized, linear, and deep forms of localized scleroderma, together with its associated subtypes. The guideline includes a description of the pathogenesis, of differential diagnoses, and particular aspects of juvenile localized scleroderma, as well as recommendations for histopathologic, serologic, and biometric diagnostic procedures. Based on studies of topical and systemic treatments as well as phototherapy for localized scleroderma published in international literature, a treatment algorithm was developed which takes account of the different subtypes and the extent of disease.

Abstract:, Localized scleroderma is a connective tissue disorder that is limited to the skin and subcutaneous tissue. Macrophages have been reported to be particularly activated in patients with skin disease including systemic sclerosis and are potentially important sources for fibrosis-inducing cytokines, such as transforming growth factor ,. To clarify the features of immunohistochemical characterization of the immune cell infiltrates in localized scleroderma focusing on macrophages, skin biopsy specimens were analysed by immunohistochemistry. The number of cells stained with monoclonal antibodies, CD68, CD163 and CD204, was calculated. An evident macrophage infiltrate and increased number of alternatively activated macrophages (M2 macrophages) in their fibrotic areas were observed along with their severity of inflammation. This study revealed that alternatively activated macrophages (M2 macrophages) may be a potential source of fibrosis-inducing cytokines in localized scleroderma, and may play a crucial role in the pathogenesis of localized scleroderma.

Simultaneous occurrence of linear scleroderma and homolateral segmental vitiligo

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 1 2006
C Bonifati
Abstract Localized scleroderma and vitiligo only rarely have been reported to occur simultaneously. Here we report a case of a 21 year old man affected with both linear scleroderma of the left upper limb and homolateral segmental vitiligo of the trunk. Since the two diseases appeared during the same period, involved the same side of the body and their progression paralleled, a possible non-coincidental association between these two diseases is discussed.

Elevated serum BAFF levels in patients with localized scleroderma in contrast to other organ-specific autoimmune diseases

EXPERIMENTAL DERMATOLOGY, Issue 2 2007
Takashi Matsushita
Abstract:, Serum levels of B-cell activating factor belonging to the tumor necrosis factor family (BAFF), a potent B-cell survival factor, are elevated in patients with systemic autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis and systemic sclerosis (SSc). The objective of this study was to determine serum BAFF levels and relate the results to the clinical features in patients with organ-specific autoimmune diseases of the skin, such as localized scleroderma and autoimmune bullous diseases. Serum BAFF levels were examined by enzyme-linked immunosorbent assay in 44 patients with localized scleroderma, 20 with pemphigus vulgaris/pemphigus foliaceus, 20 with bullous pemphigoid and 30 healthy controls. Twenty patients with SSc and 20 with SLE were also examined as disease controls. Serum BAFF levels were elevated in localized scleroderma patients compared with healthy controls. Concerning localized scleroderma subgroups, patients with generalized morphea, the severest form of localized scleroderma, had higher serum BAFF levels than linear scleroderma or morphea patients. The BAFF levels of generalized morphea were comparable with those of SSc or SLE. Furthermore, serum BAFF levels correlated positively with antihistone antibody levels and the severity of skin lesion as well as the number of skin lesions. By contrast, serum BAFF levels were not significantly elevated in patients with pemphigus or pemphigoid. These results suggest that BAFF may be contributing to autoimmunity and disease development in localized scleroderma. [source]

Photodynamic therapy in dermatology: state-of-the-art

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 3 2010
Philipp Babilas
Photodynamic therapy (PDT) has become an established treatment modality for dermatooncologic conditions like actinic keratosis, Bowen's disease, in situ squamous cell carcinoma and superficial basal cell carcinoma. There is also great promise of PDT for many non-neoplastic dermatological diseases like localized scleroderma, acne vulgaris, granuloma anulare and leishmaniasis. Aesthetic indications like photo-aged skin or sebaceous gland hyperplasia complete the range of applications. Major advantages of PDT are the low level of invasiveness and the excellent cosmetic results. Here, we review the principal mechanism of action, the current developments in the field of photosensitizers and light sources, practical aspects of topical PDT and therapeutical applications in oncologic as well as non-oncologic indications.

Ultraviolet A1 phototherapy for treatment of acrosclerosis in systemic sclerosis: controlled study with half-side comparison analysis

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 6 2007
F. Durand
Background: Treatments currently used in acrosclerosis for patients with systemic sclerosis (SS) are not very efficient and are associated with adverse effects. Several reports concern the efficacy of ultraviolet A1 (UVA1) phototherapy for localized scleroderma. Recent studies appear to indicate the interest of UVA1 in acrosclerosis for patients with SS. However, these studies are uncontrolled. Objective: To determine whether UVA1 phototherapy is effective for acrosclerosis in SS with a randomized, investigator-blinded, controlled study. Methods: Nine patients with SS completed the study. The duration of disease ranged from 6 to 21 years. None of them had received glucocorticoids or immunosuppressive agents. Low-dose UVA1 phototherapy (40 J/cm2) of the randomized hand was performed three times weekly over a period of 14 weeks. The other hand served as control. The clinical evaluation used a modified semiquantitative skin scoring system, the index flexion and extension, and a visual analog scale (VAS) was performed at baseline and after treatment. Results: The mean of skin score and VAS improved significantly (P<0.05), but this improvement does not appear to be different between the treated or the untreated hands. There was no modification of the index flexion or extension. Two patients noticeably improved the functions of the treated hand. No side effects were observed. Conclusions: These results suggest that UVA1 phototherapy does not improve cutaneous thickness in acrosclerosis even if few functional improvements, and some ulcerations healings can be occasionally observed. However, a larger scale trial is necessary to confirm this inefficiency. [source]

Phototherapy and photochemotherapy of sclerosing skin diseases

The treatment of sclerosing skin diseases [systemic sclerosis, localized scleroderma, lichen sclerosus et atrophicus, sclerodermoid graft-vs.-host disease, scleredema adultorum (Buschke), scleromyxedema and necrobiosis lipoidica] is difficult and remains a great challenge. Numerous treatments, some with potentially hazardous side effects, are currently used with only limited success. The introduction of phototherapy and photochemotherapy for sclerosing skin diseases has considerably enriched the therapeutic panel and proven useful in a number of sclerosing skin diseases especially in localized scleroderma. Two phototherapeutic modalitites are used for the treatment of sclerosing skin diseases, long-wave ultraviolet A and psoralen plus ultraviolet A (PUVA). This article reviews current knowledge about the application of phototherapy and photochemotherapy to various sclerosing skin disorders. [source]

Effects of low dose ultraviolet A-1 phototherapy on morphea

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 4 2001
Claus J. Gruss
Aim: The effects of low dose ultraviolet A-1 (UVA-1) phototherapy on different clinical stages of morphea (localized scleroderma) were analyzed in this case study. Based on these data, the different types of phototherapy described in the literature and currently used for treatment of morphea are compared. Methods: Three patients with severe plaque type morphea in different stages were studied: one patient with late-stage lesions having stable sclerotic plaques; another patient with active inflammatory lesions; and a third patient with late-stage lesions associated with overlying lichen sclerosus et atrophicus (LSA). The treatment given was low dose UVA-1 phototherapy with single doses of 20 J/cm2 administered four times a week for 6 weeks, and once a week for another 6 weeks. Results: Following UVA-1 phototherapy, the sclerotic plaques resolved, leaving smooth and soft tanned skin with normal structure, consistency and folding capability. In morphea with overlying LSA the elastic fibers did not completely return to the superficial papillary dermis despite the clinical clearance of both morphea and LSA. These data suggest that low dose UVA-1 phototherapy may improve, but not completely reverse, the histopathological changes of LSA. No side effects were observed during or after treatment. Conclusion: Our observations show in three patients that low-dose UVA-1 phototherapy is highly effective for treatment of all stages of morphea, including early inflammatory and late sclerotic lesions, and morphea with overlying lichen sclerosus et atrophicus. Because of its safety and efficacy, low dose UVA-1 phototherapy appears to be the treatment modality of choice. [source]

Low-dose broad-band UVA in morphea using a new method for evaluation

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 2 2000
M. El-Mofty
Until recently, various therapies for localized scleroderma have been used with limited success. Recently, phototherapy, with or without psoralen, was proposed as a successful treatment modality. The aim of this study was to evaluate the effect of broad-band low-dose ultraviolet A (UVA) phototherapy in patients with localized scleroderma, using a new method for evaluation. Twelve patients complaining of morphea were exposed to UVA irradiation at a dose of 20 J/cm2 3 times per week for 20 sessions. Selected covered plaques served as internal controls. The efficacy of therapy was judged clinically by sequential inspection and palpation. In biopsy specimens from exposed and covered plaques stained with hematoxylin and eosin (H & E) and Masson trichrome stains, the concentration of collagen per dermal surface area was measured with the use of a computerized image analyzer. All patients reported remarkable softening of skin lesions, confirmed by sequential palpatory assessment. A significant reduction in the mean concentration of collagen per surface area was detected in the plaques exposed to UVA (the P value being 0.007, P<0.01), whereas in the covered plaques the difference was not statistically significant (the P value being 0.10, P>0.05). The conclusion is that low-dose broad-band UVA phototherapy is a very effective and safe treatment modality for localized scleroderma. [source]

Case of localized scleroderma associated with osteomyelitis

Abstract We report a 4-year-old girl presenting with progressive linear scleroderma affecting the right leg. Biopsy specimen disclosed typical histopathological findings of localized scleroderma. Right leg magnetic resonance imaging (MRI) showed high signal areas on T2 -weighted images on the subcutaneous fatty tissue, muscles and bone marrow, suggesting that skin inflammation extended to the bone marrow. Oral corticosteroid therapy was instituted with improvement of both skin sclerosis and MRI findings. Our observations suggest that MRI examination should be considered in patients with localized scleroderma to evaluate the extension of the inflammation. [source]

Familial associations of rheumatoid arthritis with autoimmune diseases and related conditions

ARTHRITIS & RHEUMATISM, Issue 3 2009
Kari Hemminki
Objective In the era of genome-wide association studies, familial risks are used to estimate disease heritability and the likelihood of candidate-gene identification. This study was undertaken to estimate associations of rheumatoid arthritis (RA) with any of 33 autoimmune diseases and related conditions among parents and offspring, singleton siblings, twins, and spouses. Methods The Multigeneration Register in Sweden was used as a reliable source of information on Swedish families throughout the last century. Data on autoimmune diseases in individual family members were obtained through linkage to the Hospital Discharge Register. The standardized incidence ratio (SIR) was calculated as a measure of the relative risk of RA in family members of patients with RA or any of 33 other autoimmune diseases or related conditions, as compared with the relative risk of RA in those lacking an affected family member. Results Among a total of 447,704 patients, 47,361 were diagnosed as having RA. The SIRs for RA were 3.02 in offspring of affected parents, 4.64 in siblings, 9.31 in multiplex families, 6.48 in twins, and 1.17 in spouses. Significant associations with the familial risk of RA in offspring according to parental proband were observed for ankylosing spondylitis (SIR 2.96), localized scleroderma (SIR 2.40), Sjögren's syndrome (SIR 2.25), systemic lupus erythematosus (SIR 2.13), systemic sclerosis (SIR 1.65), Hashimoto thyroiditis/hypothyroidism (SIR 1.54), pernicious anemia (SIR 1.53), sarcoidosis (SIR 1.40), psoriasis (SIR 1.36), Wegener's granulomatosis (SIR 1.34), and asthma or polymyalgia rheumatica (SIR 1.32). Conclusion This is the first study to compare the familial risks of RA in relation to a large number of autoimmune diseases and related conditions using data from a single population. The high discordant familial risks in this population suggest that there is extensive genetic sharing between RA and the associated diseases. [source]

Eosinophilic fasciitis treated with psoralen-ultraviolet A bath photochemotherapy

BRITISH JOURNAL OF DERMATOLOGY, Issue 4 2000
R. Schiener
Eosinophilic fasciitis is a rare disorder which can markedly affect the quality of life in individual patients. So far, no generally accepted and effective treatment modality has been available. Although the precise nature of eosinophilic fasciitis is still unknown, it is often regarded as a variant of localized scleroderma (morphoea). Phototherapy and photochemotherapy have been shown to be effective in the treatment of sclerodermatous skin lesions. We report a patient with eosinophilic fasciitis which was successfully treated with psoralen plus ultraviolet A bath photochemotherapy within 6 months. [source]

Guttate morphoea in human T-cell lymphoma/lymphotrophic virus type-1 (HTLV-1) infection

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 4 2003
N. Oiso
Summary A 62-year-old Japanese man presented with multiple small atrophic macules on the trunk and extremities. The lesions were discrete, oval in shape and enclosed by lilac ring. They were distributed in a Christmas tree distribution, reminiscent of pityriasis rosea. Skin biopsy showed increased collagen fibres in the dermis and invading subcutaneous tissue. The clinico-pathological features were consistent with guttate morphoea, a rare variant of localized scleroderma. Serological tests revealed a positive reaction to human T-cell lymphoma/lymphotropic virus type-1 infection. [source]
