Lichenoid and subacute cutaneous lupus erythematosus-like dermatitis associated with antihistamine therapy

Cutaneous lupus erythematosus induced by drugs - novel insights

Introduction: There is a growing list of drugs implicated in inducing both subacute and chronic forms of cutaneous lupus erythematosus. It is important to recognize these drugs in order to quickly treat patients with drug induced disease.Areas covered: This paper reviews the current literature describing drugs implicated in causing cutaneous lupus erythematosus. A Pubmed search was used to compile a list of medications implicated up to August 2019. It reviews new classes of drugs identified as causing cutaneous lupus erythematosus, the pathophysiology of the disease process, and current recommendations for treatment of the disease.Expert opinion: Many drugs have been identified as inducing lupus, and many more continue to be described in new reports. Further research is needed to understand this phenomenon, which will aid in the diagnosis and treatment of affected patients.

Lichenoid and interface dermatoses

The terms 'lichenoid' and 'interface' dermatitis are often used interchangeably to describe an inflammatory pattern characterized histologically by damage to the basal keratinocytes in the epidermis. The mechanism of cell damage of such cells is now best understood as apoptosis, or programmed cell death. This inflammatory pattern of dermatoses, is also accompanied frequently by a band of lymphocytes and histiocytes in the superficial dermis, that often obscures the dermal-epidermal junction, hence the term 'lichenoid'. A discussion of the more common lichenoid/interface dermatitides encountered in the routine clinical practice encompasses the following entities: lichen planus, lupus erythematosus, dermatomyositis, erythema multiforme, graft versus host disease, fixed drug reactions, and multiple others.

Trigger factors of cutaneous lupus erythematosus: a review of current literature

It is currently believed that autoimmune conditions are triggered and aggravated by a variety of environmental factors such as cigarette smoking, infections, ultraviolet light or chemicals, as well as certain medications and vaccines in genetically susceptible individuals. Recent scientific data have suggested a relevant role of these factors not only in systemic lupus erythematosus, but also in cutaneous lupus erythematosus (CLE). A variety of environmental factors have been proposed as initiators and exacerbators of this disease. In this review we focused on those with the most convincing evidence, emphasizing the role of drugs in CLE. Using a combined search strategy of the MEDLINE and CINAHL databases the following trigger factors and/or exacerbators of CLE have been identified and described: drugs, smoking, neoplasms, ultraviolet radiation and radiotherapy. In order to give a practical insight we emphasized the role of drugs from various groups and classes in CLE. We also aimed to present a short clinical profile of patients with lesions induced by various drug classes.

Antimalarial lichenoid tissue reactions in patients with pre-existing lupus erythematosus

Recently a number of cases of drug induction or exacerbation of lupus erythematosus (LE) specific skin disease have been described in the literature. Many of the responsible medications are also known for their ability to induce a lichenoid tissue reaction. Aminoquinoline antimalarials are currently the first line of therapy in cutaneous LE specific skin disease. Lichenoid tissue reactions are among the most common cutaneous side effects of aminoquinolone antimalarials. We report three cases of aminoquinolone antimalarial induced or exacerbated LE specific skin disease. We also review the pathophysiology of LE specific skin disease and propose a mechanism by which induction of the lichenoid tissue reaction may result in Koebnerization of LE specific skin lesions.

Subacute cutaneous lupus erythematosus and its association with drugs: a population-based matched case-control study of 234 patients in Sweden

BACKGROUND

Numerous case reports about drug-induced (DI) subacute cutaneous lupus erythematosus (SCLE) have been published. Various drug types with different latencies has been proposed as triggers for this autoimmune skin disease.

OBJECTIVES

To evaluate the association between exposure to certain suspected drugs (previously implicated to induce SCLE) and a subsequent diagnosis of SCLE.

METHODS

We performed a population-based matched case-control study in which all incident cases of SCLE (n=34) from 2006 to 2009 were derived from the National Patient Register. The control group was selected from the general population, matched (1:10) for gender, age and county of residence. The data were linked to the Prescribed Drug Register. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for the association between exposures to certain suspected drugs and the development of SCLE.

RESULTS

During the 6 months preceding SCLE diagnosis, 166 (71%) of the patients with SCLE had at least one filled prescription of the suspected drugs. The most increased ORs were found for terbinafine (OR 52.9, 95% CI 6.6-∞), tumour necrosis factor-α inhibitors (OR 8.0, 95% CI 1.6-37.2), antiepileptics (OR 3.4, 95% CI 1.9-5.8) and proton pump inhibitors (OR 2.9, 95% CI 2.0-4.0).

CONCLUSIONS

We found an association between drug exposure and SCLE. More than one third of the SCLE cases could be attributed to drug exposure. No significant OR was found for thiazides, which might be due to longer latency and therefore missed with this study design. DI-SCLE is reversible once the drug is discontinued, indicating the importance of screening patients with SCLE for potentially triggering drugs. A causal relationship cannot be established from this study and the underlying pathogenesis remains unclear.

A systematic review of drug-induced subacute cutaneous lupus erythematosus

The initial appearance of subacute cutaneous lupus erythematosus (SCLE) skin lesions in conjunction with Ro/SS-A autoantibodies occurring as an adverse reaction to hydrochlorothiazide [i.e. drug-induced SCLE (DI-SCLE)] was first reported in 1985. Over the past decade an increasing number of drugs in different classes has been implicated as triggers for DI-SCLE. The management of DI-SCLE can be especially challenging in patients taking multiple medications capable of triggering DI-SCLE. Our objectives were to review the published English language literature on DI-SCLE and use the resulting summary data pool to address questions surrounding drug-induced SCLE and to develop guidelines that might be of value to clinicians in the diagnosis and management of DI-SCLE. A systematic review of the Medline/PubMed-cited literature on DI-SCLE up to August 2009 was performed. Our data collection and analysis strategies were prospectively designed to answer a series of questions related to the clinical, prognostic and pathogenetic significance of DI-SCLE. One hundred and seventeen cases of DI-SCLE were identified and reviewed. White women made up the large majority of cases, and the mean overall age was 58·0 years. Triggering drugs fell into a number of different classes, highlighted by antihypertensives and antifungals. Time intervals ('incubation period') between drug exposure and appearance of DI-SCLE varied greatly and were drug class dependent. Most cases of DI-SCLE spontaneously resolved within weeks of drug withdrawal. Ro/SS-A autoantibodies were present in 80% of the cases in which such data were reported and most remained positive after resolution of SCLE skin disease activity. No significant differences in the clinical, histopathological or immunopathological features between DI-SCLE and idiopathic SCLE were detected. There is now adequate published experience to suggest that DI-SCLE does not differ clinically, histopathologically or immunologically from idiopathic SCLE. It should be recognized as a distinct clinical constellation differing clinically and immunologically from the classical form of drug-induced systemic lupus erythematosus.

Drug-induced subacute cutaneous lupus erythematosus

Subacute cutaneous lupus erythematosus (SCLE) is a subset of cutaneous lupus erythematosus with unique immunologic and clinical features. The first description dates back to 1985 when a series of five patients were found to have hydrochlorothiazide-induced SCLE. Since that time, at least 40 other drugs have been implicated in the induction of SCLE.

Interface dermatitis

Interface dermatitis can be classified based upon the cell type that dominates the infiltrate (ie, neutrophilic, lymphocytic, or lymphohistiocytic) or by the intensity of the interface inflammation. Regarding lymphocytic interface dermatitis, there are 2 broad categories: cell-poor interface dermatitis, when only a sparse infiltrate of inflammatory cells is present along the dermoepidermal junction, or cell rich, which typically occurs as a heavy bandlike infiltrate that obscures the basal layers of the epidermis. In the case of lymphocytic interface dermatitis, the latter is often termed a lichenoid interface dermatitis. This review focuses upon the mononuclear cell-predominant forms of interface dermatitis.

Cutaneous lupus erythematosus: A personal approach to management

SUMMARY Skin disease in patients with lupus erythematosus may be subdivided into two broad categories - those lesions that when biopsied demonstrate interface dermatitis and those that do not demonstrate interface dermatitis. The skin lesions that are represented by the interface dermatitis include discoid lupus erythematosus, subacute cutaneous lupus erythematosus and acute cutaneous lupus erythematosus. Patients with these 'specific' manifestations have varying degrees of systemic involvement from rare systemic disease in patients with localized discoid lupus erythematosus to common and often severe involvement in patients with acute cutaneous lupus erythematosus. Patients who do not demonstrate interface dermatitis also may have systemic disease and in some instances the skin manifestations are linked to some of the more severe systemic manifestations. Many patients with cutaneous lesions characterized by the interface dermatitis can be controlled with 'standard' therapies including sunscreens, protective clothing and behavioural alteration, and topical corticosteroids with or without an oral antimalarial agent. This review presents a brief summary of each common cutaneous manifestation of lupus erythematosus, its relationship to systemic involvement and treatment issues to effectively deal with the lupus erythematosus patient who has skin disease.

Acebutolol-Induced Subacute Cutaneous Lupus Erythematosus

Beta-blocking medications are rarely associated with drug-induced lupus erythematosus syndrome and have never been incriminated as a cause of subacute lupus erythematosus (SCLE). We present herein the first case of SCLE induced by acebutolol. A 57-year-old woman presented with a 1-month history of a cutaneous eruption of the photo-exposed areas. One month ago, the patient had started a treatment with oral acebutolol to cure a hypertension of 1-year evolution. Physical examination revealed erythematous scaly annular plaques, involving the face, arms and trunk. Immunologic serology findings revealed a positive titer of antinuclear antibodies up to 1/1,280 with positivity of antihistone and Ro/SSA antibodies. Acebutolol was stopped, and the lesions cleared completely 4 months later. Literature data, along with our case, suggest a link between acebutolol therapy and the onset of a lupus syndrome. Although this is the first report of acebutolol-induced SCLE, we should be aware of this occurrence, and avoidance of acebutolol is recommended in patients with stigmata of lupus erythematosus.

Lupus erythematosus induced by medications, ultraviolet radiation, and other exogenous agents: A review, with special focus on the development of subacute cutaneous lupus erythematosus in a genetically predisposed individual

Exogenous agents implicated in or suspected of precipitating subacute cutaneous lupus erythematosus (SCLE) and lupus erythematosus (LE) are reviewed. An illustrative case of environmentally induced SCLE is presented. A previously healthy 30-year male homozygous for the tumor necrosis factor-alpha (TNF-alpha) 308. A promoter allele developed SCLE after spending several hours removing fertilizer- and pesticide-containing hay from an agricultural barn in the springtime. The cutaneous eruption soon resolved, only to reappear 3 weeks later on the day the patient re-entered the barn. An environmental agent present in the barn, coupled with springtime ultraviolet light, likely triggered the disease in this immunogenetically susceptible individual.

Progress in the understanding of the pathology and pathogenesis of cutaneous drug eruptions : implications for management

Cutaneous drug eruptions are among the most common adverse reactions to drug therapy. The etiology may reflect immunologic or nonimmunologic mechanisms, the former encompassing all of the classic Gell and Combs immune mechanisms. Cumulative and synergistic effects of drugs include those interactions of pharmacokinetic and pharmacodynamic factors reflecting the alteration by one drug of the effective serum concentration of another and the functions of drugs and their metabolites that interact to evoke cutaneous and systemic adverse reactions. Recent observations include the role of concurrent infection with lymphotropic viruses and drug effects that, through the enhancement of lymphoid blast transformation and/or lymphocyte survival and the contribution of intercurrent systemic connective tissue disease syndromes, promote enhanced lymphocyte longevity and the acquisition of progressively broadening autoantibody specificities. The latter are particularly opposite to drug-induced lupus erythematosus and to drug reactions in the setting of HIV infection. Specific common types of cutaneous drug eruptions will be discussed in this review. Successful management of cutaneous drug eruptions relies upon the prompt discontinuation of the causative medication; most drug eruptions have a good prognosis after this is accomplished. Oral or topical corticosteroids can be administered to aid in the resolution of some types of eruptions. Antihistamines or anti-inflammatory agents may also be administered for some eruptions.

Terbinafine-induced subacute cutaneous lupus erythematosus

BACKGROUND

Recently, the induction of subacute cutaneous lupus erythematosus (SCLE) and exacerbation of systemic lupus erythematosus by terbinafine have been reported.

OBJECTIVE

We describe 4 cases of SCLE, one associated with chilblain lupus, which occurred during therapy with oral terbinafine for onychomycosis.

METHODS

Of 21 consecutive patients with SCLE attending the outpatient dermatology department at Muenster University clinic during a 1-year period, 4 patients with terbinafine-induced SCLE were seen. Patients were examined fully and photographed; histologic findings as well as serologic and follow-up data were evaluated.

RESULTS

In addition to high titers of antinuclear antibodies (ANA) with a homogeneous pattern, anti-Ro(SS-A) antibodies were present; in 3 of 4 women, anti-La(SS-B) antibodies were also found. All patients had anti-histone antibodies as in drug-induced lupus and showed the characteristic genetic association of SCLE with the HLA-B8,DR3 haplotype; moreover, in 2 cases, HLA-DR2 was also present. After discontinuation of terbinafine, ANA titers decreased; anti-histone antibodies also became undetectable within 4(1/2) months in 3 patients concomitant with subsidence of the SCLE eruption in all patients.

CONCLUSION

Terbinafine is a drug that appears to infrequently induce SCLE with high titers of ANAs and anti-histone antibodies in genetically susceptible persons.

The cutaneous pathology of lupus erythematosus: a review

The presentation of lupus erythematosus (LE) ranges from a skin rash unaccompanied by extracutaneous stigmata to a rapidly progressive lethal multiorgan disease. The diagnosis and subclassification is traditionally based on the correlation of serological and clinical findings. The latter include a photoinduced skin rash, arthralgia, arthritis, fever, Raynaud's phenomenon, anemia, leukopenia, serositis, nephritis and central nervous sysdtem disease. The conventional classification scheme includes systemic, subacute cutaneous and discoid LE. Recent advances in our understanding of the cutaneous histopathology which correlates with the traditional forms of LE, along with certain novel LE subtypes, are the focus of this review. In addition to the main subtypes of LE, we will discuss associated vasculopathic lesions and the contribution of immunofluorescence microscopy to the diagnosis of LE and related connective tissue disease syndromes. Consideration will be given to unusual variants of LE such as anti-Ro/SSA-positive systemic lupus erythematosus (SLE), bullous SLE, lymphomatoid LE, lupus erythematosus profundus, drug induced LE, linear cutaneous LE, chiblains LE and parvovirus B19-associated LE.

Recent advances in the pathology of cutaneous drug eruptions

Cutaneous reactions to drug therapy may be of either immunologic or nonimmunologic etiology. It is important that the dermatologist and pathologist be familiar with these types of cutaneous reactions. This article discusses the clinical features, pathogenesis, and histopathology of various cutaneous drug eruptions.
