Efficacy of anifrolumab in long-term intractable alopecia due to discoid lupus erythematosus.

Alopecia associated with lupus erythematosus is broadly classified into reversible nonscarring alopecia seen in the acute phase, such as worsening of systemic lupus erythematosus (SLE) and cicatricial alopecia seen in chronic cutaneous lupus erythematosus represented by discoid lupus erythematosus (DLE). In DLE-induced alopecia, early therapeutic intervention before developing scarring alopecia is important, but the condition is often resistant to conventional treatment. Anifrolumab (ANI), a novel therapeutic agent for SLE that inhibits Type I interferon activity, has been shown to be effective against acute skin lesions, including alopecia, in patients with SLE. However, there are very few reports on the effect of ANI on alopecia due to DLE. We report on a 27-year-old Japanese woman with SLE whose alopecia due to chronic DLE was refractory to topical therapy and systemic therapy with oral glucocorticoid, multiple immunosuppressants, and belimumab for ∼8 years after onset and whose alopecia improved with ANI. ANI can be considered to be an effective treatment option in lupus patients presenting with alopecia due to DLE, even in the chronic refractory stage.

Morphea-like discoid lupus erythematosus in a patient with a history of polyacrylamide gel injection: A case report.

BACKGROUND: Discoid lupus erythematosus (DLE) is an autoimmune disease with multifactor etiology which develops in genetically susceptible patients. Rarely, DLE lesions can mimic other connective tissue disorders such as morphea. The growing application of soft tissue fillers is associated with increasing complications. Some substances used for soft tissue augmentation such as silicon implants may trigger lupus erythematosus diseases. CASE REPORT: Here we report a case of morphea-like discoid lupus erythematosus developed several years after polyacrylamide dermal filler (PAAG) injection for facial rejuvenation. CONCLUSION: As noninvasive procedures like dermal filler injections are increasing worldwide, physicians may consider the long-term probable side effects of these compounds.

Case report of canine discoid lupus erythematosus in Guatemala.

An 11-year-old male Golden Retriever was presented for consultation due to a chronic progressive lesion on the nose that had started a year before. The majority of the nasal mucosa was affected, with the disruption of the normal architecture, pigment atrophy and abundant peeling on the rostral plane. Histopathology revealed a band of lichenoid infiltrate at the interface and vacuolation of the cells in the basal layer consistent with a diagnosis of canine discoid lupus erythematosus.

Cutaneous lupus erythematosus is associated with an increased risk of cardiac and vascular diseases: a large-scale, propensity-matched global retrospective cohort study.

BACKGROUND: Autoimmune skin diseases can expedite various systemic sequelae involving other organs. Although limited to the skin, cutaneous lupus erythematosus (CLE) was noted to be associated with thromboembolic diseases. However, small cohort sizes, partially discrepant outcomes, missing data on CLE subtypes, and incomplete risk assessment limits these findings. METHODS: The Global Collaborative Network of TriNetX provides access to medical records of more than 120 million patients worldwide. We used TriNetX to elucidate the risk for cardiac and vascular diseases after diagnosis of CLE, and its subtypes chronic discoid (DLE) and subacute cutaneous lupus erythematosus (SCLE). We included 30,315 CLE, 27,427 DLE, and 1613 SCLE patients. We performed propensity-matched cohort studies determining the risk to develop cardiac and vascular diseases (ICD10CM:I00-99) following diagnosis of CLE, DLE, or SCLE. Patients with systemic lupus erythematosus were excluded. FINDINGS: We document that CLE and its subtype DLE but less so SCLE are associated with a higher risk for various cardiac and vascular diseases. This included predominantly thromboembolic events such as pulmonary embolism, cerebral infarction, and acute myocardial infarction, but also peripheral vascular disease and pericarditis. For example, the hazard ratio of arterial embolism and thrombosis was 1.399 (confidence interval: 1.230-1.591, p < 0.0001) following CLE diagnosis. The study is limited by retrospective data collection and reliance on ICD10-disease classification. INTERPRETATION: CLE and its major subtype DLE are associated with an increased risk for the development of a wide range of cardiac and vascular diseases. FUNDING: This research was funded by Deutsche Forschungsgemeinschaft (EXC 2167, CSSL/CS01-2022) and the Excellence-Chair Program of the State of Schleswig-Holstein.

Systemic lupus erythematosus presenting as lupus erythematosus tumidus and lupus nephritis: a case report.

BACKGROUND: Lupus nephritis and lupus erythematosus tumidus (LET) are uncommon manifestations of systemic lupus erythematosus (SLE), and their coexistence as the initial presentation of SLE is exceedingly rare. Here, we report such a case, emphasizing the diagnostic challenges and therapeutic implications of this unusual association. CASE REPORT: A 38-year-old North African woman presented in Nephrology department with a history of lower extremity edema, fatigue, and weight loss of 3 kg in 4 weeks. Physical examination revealed LET lesions on the chest and the Neck. Laboratory investigations showed lymphopenia, low C3 and C4 complement levels, positive antinuclear antibodies, anti-dsDNA antibodies, and anti-SSA/Ro antibodies. Renal function tests showed normal serum creatinine and nephrotic proteinuria. Renal biopsy revealed Class V lupus nephritis. Skin biopsy confirmed the diagnosis of LET, with the presence of lymphohistiocytic infiltrates and dermal mucin. The patient was diagnosed with SLE based on the 2019 EULAR/ACR criteria and treated with prednisone (1 mg/kg/day) and hydroxychloroquine. She showed significant improvement in her cutaneous and renal symptoms at 6 and 12 months follow-up. CONCLUSION: The rarity of the coexistence of LET and lupus nephritis as the initial manifestation of SLE, especially in the North African population, underscores the need for further research to elucidate the immunopathogenic mechanisms and prognostic factors associated with this association.

Collagen Vascular Diseases: A Review of Cutaneous and Systemic Lupus Erythematosus, Dermatomyositis, and Distinguishing Features in Skin of Color.

Collagen vascular diseases such as lupus erythematosus and dermatomyositis (DM) occur 2 to 3 times more often among patients with skin of color. In this article, the authors review DM and cutaneous lupus erythematosus, including acute cutaneous lupus erythematosus, subacute cutaneous lupus erythematosus, and discoid lupus erythematosus. They discuss the distinguishing features between these entities and highlight distinct presentations and management considerations in patients with skin of color to aid in prompt and correct diagnoses in this patient population.

Scarring Alopecia.

African hair shaft and pigmented scalp have unique features that challenge diagnosis in scarring alopecia. In addition, Black patients may associate 2 or more types of hair disorders. Therefore, it is imperative to understand their findings thoroughly to establish a good diagnosis. Differential diagnosis on the frontal scalp includes traction alopecia and frontal fibrosing alopecia. Disorders such as central centrifugal cicatricial alopecia, fibrosing alopecia in a pattern distribution, discoid lupus erythematosus, and lichen planopilaris usually affect the middle scalp. Folliculitis decalvans, dissecting cellulitis, and acne keloidalis nuchae are the main differential diagnosis of the posterior scalp.

A 30-Year-Old Woman with a History of Autoimmune Hyperthyroidism Presenting with Fever and Oral Ulcers, Diagnosed with Discoid Lupus Erythematosus.

BACKGROUND Lupus erythematosus (LE) is mainly clinically divided into cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) depending on the presence of multi-system manifestations. The most common subtype of CLE is discoid lupus erythematosus (DLE). Graves' disease (GD) is immunologically characterized by lymphocytic infiltration of the thyroid gland and the presence of thyroid-stimulating hormone (TSH) receptor antibodies (TSH-R-Ab), and is the most common autoimmune pathogenic cause of hyperthyroidism. Autoimmune thyroid dysfunction has been widely described in association with rheumatic diseases. A certain rate of coexistence of GD with LE, mainly SLE, has been reported in the literature. Herein, we present a rare case of Graves' hyperthyroidism complicated with DLE. CASE REPORT A 30-year-old female patient, with a history of hyperthyroidism and discontinued methimazole treatment, initially presented with symptoms of infection and oral ulcers. Thyroid hormone, thyroid-stimulating hormone receptor antibody, and immunological tests were consistent with a diagnosis of Graves' hyperthyroidism-associated DLE. Corticosteroids and radioactive iodine (RAI) were used to treat DLE and GD, respectively. Post-treatment evaluation suggested the remission of her hyperthyroidism and active DLE. CONCLUSIONS Autoimmune thyroid diseases have been previously described in association with rheumatic diseases. This association shows the importance of prompt awareness of the increased risk of DLE when evaluating autoimmune thyroid dysfunction, especially under certain conditions, such as after treatment with anti-thyroid drugs (ATDs), or in the absence of multiple organ damage manifestations of SLE.

Open-Label Phase 2 Pilot Study of Oral Tofacitinib in Adult Subjects With Discoid Lupus Erythematosus (DLE).

CITATION: Alsukait S, Learned C, Rosmarin D. Open-label phase 2 pilot study of oral tofacitinib in adult subjects with Discoid Lupus Erythematosus (DLE). J Drugs Dermatol. 2023;22(4): 425-427. doi:10.36849/JDD.7098.

Comedonic lupus, a rare variant of chronic cutaneous lupus erythematosus (CCLE): case series and literature review.

BACKGROUND: Cutaneous lupus erythematosus (CLE) is an autoimmune disease with several clinical presentations. The chronic form predominantly presents as discoid rashes but may present with less common morphological findings that can sometimes make diagnosis difficult. Comedonic lupus is a rare and underdiagnosed variant, with unknown etiology and still poorly defined treatment. METHODS: The report illustrates a series of five cases of patients diagnosed with comedonic lupus, and it reviews 18 cases previously published in the literature. RESULTS: The clinical presentation is of comedonal lesions, mostly located on the face, making a differential diagnosis with other benign conditions such as acne vulgaris, Favre-Racouchot syndrome, and syringoma, emphasizing the importance of clinical practice and histopathology for diagnostic confirmation. CONCLUSIONS: There is scarcity in the literature regarding the condition and therapeutic possibilities for these cases of comedonic lupus.

Assessment of Clinical Response to Anifrolumab in Patients With Refractory Discoid Lupus Erythematosus.

This case series examines the efficacy of anifrolumab as a therapeutic option for patients with lupus erythematosus.

Comedogenic lupus: a rare variant of chronic cutaneous lupus erythematosus - case series.

BACKGROUND: Comedogenic lupus is an uncommon variant of cutaneous lupus, clinically characterized by the presence of comedones, papules and erythematous-infiltrated plaques, cysts and scars in photo-exposed areas, mimicking acne vulgaris and acneiform eruptions. OBJECTIVES: To report clinicopathological characteristics of patients with comedogenic lupus in a tertiary dermatology service over a 15-year period and review cases described in the literature. METHODS: Retrospective study of patients with clinical and histopathological diagnoses of comedogenic lupus between the years 2006 and 2021. The literature search was carried out in the PubMed and VHL Regional Portal databases, using the terms: "comedogenic lupus" and "acneiform lupus" in Portuguese and English. RESULTS: Five patients were diagnosed during the described period, all female, with a mean age of 56.6 years. Smoking was observed in three cases, as well as pruritus. The most affected site was the face, especially the pre-auricular, malar and chin regions. Follicular plugs, epidermal thinning and liquefaction degeneration of the basal layer were predominant histopathological findings. Hydroxychloroquine was used as the first-line treatment; however, other medications were used, such as dapsone, methotrexate, tretinoin cream, and topical corticosteroids. The literature search identified 17 cases, with a mean age of 38.9 years, 82% of which were women. Only 23% had a diagnosis of systemic lupus erythematosus. Hydroxychloroquine was the most recommended systemic medication. STUDY LIMITATIONS: Retrospective, single-center study. The literature search was carried out in two databases. CONCLUSIONS: Dermatologists should be aware of acneiform conditions with poor response to the usual treatment. Early diagnosis and treatment reduce the risk of unaesthetic scars.

Linear discoid lupus erythematous simulating en coup de sabre morphea in a female chronic granulomatous disease carrier.

Discoid lupus erythematosus (DLE), a subtype of chronic cutaneous lupus may be observed in a linear pattern. A 21-year-old woman with history of chronic granulomatous disease state presented to our clinic for a chronic six-year skin eruption on her left eyebrow, left cheek, and left forehead. A punch biopsy of involved left forehead skin was performed and revealed perivascular and periadnexal lymphohistiocytic infiltrate without features of morphea or panniculitis, confirming the histopathologic changes of cutaneous lupus erythematous. The patient was diagnosed with linear DLE, mimicking en coup de sabre, within Blaschko lines. The pathogenesis for DLE in association with chronic granulomatous disease is ambiguous; however, X-linked lyonization is crucial for both conditions and may explain cooccurrence of disease states.

Depression, stigma and social isolation: the psychosocial trifecta of primary chronic cutaneous lupus erythematosus, a cross-sectional and path analysis.

OBJECTIVE: Depression is common in individuals with chronic cutaneous lupus erythematosus (CCLE). However, how CCLE may impact patients' psychological well-being is poorly understood, particularly among disproportionally affected populations. We examined the relationships between depression and psychosocial factors in a cohort of predominantly Black patients with primary CCLE (CCLE without systemic manifestations). METHODS: Cross-sectional assessment of individuals with dermatologist-validated diagnosis of primary CCLE. NIH-PROMIS short-forms were used to measure depression, disease-related stigma, social isolation and emotional support. Linear regression analyses (ɑ=0.05) were used to test an a priori conceptual model of the relationship between stigma and depression and the effect of social isolation and emotional support on that association. RESULTS: Among 121 participants (87.6% women; 85.1% Black), 37 (30.6%) reported moderate to severe depression. Distributions of examined variables divided equally among those which did (eg, work status, stigma (more), social isolation (more), emotional support (less)) and did not (eg, age, sex, race, marital status) significantly differ by depression. Stigma was significantly associated with depression (b=0.77; 95% CI0.65 to 0.90), whereas social isolation was associated with both stigma (b=0.85; 95% CI 0.72 to 0.97) and depression (b=0.70; 95% CI0.58 to 0.92). After controlling for confounders, stigma remained associated with depression (b=0.44; 95% CI0.23 to 0.66) but lost significance (b=0.12; 95% CI -0.14 to 0.39) when social isolation (b=0.40; 95% CI 0.19 to 0.62) was added to the model. Social isolation explained 72% of the total effect of stigma on depression. Emotional support was inversely associated with depression in the univariate analysis; however, no buffer effect was found when it was added to the multivariate model. CONCLUSION: Our findings emphasise the psychosocial challenges faced by individuals living with primary CCLE. The path analysis suggests that stigmatisation and social isolation might lead to depressive symptoms. Early clinical identification of social isolation and public education demystifying CCLE could help reduce depression in patients with CCLE.
