Livedoid vasculopathy: fast involution after anticoagulant and hyperbaric oxygen therapy

Livedoid vasculopathy: A multidisciplinary clinical approach to diagnosis and management

Livedoid vasculopathy (LV) is a rare, chronic, and occlusive disease of the veins supplying the upper parts of the skin. The pathogenesis of the disease is not precisely understood, and its attacks are often unpredictable but tend to worsen during the summer. LV affects women more often. This increased risk for LV in women might be related to sex-specific physiological conditions, such as pregnancy, or a higher incidence of LV-associated conditions, such as connective tissue diseases, hypercoagulable states, and venous stasis in women. The typical clinical appearance of LV consists of three main findings: livedo racemose, atrophie blanche, and skin ulcers. The purpose of this comprehensive review was to analyze LV in all aspects and mainly focus on early diagnosis for successful clinical management with a holistic and multidisciplinary approach. A detailed history, dermatological examination, and laboratory testing are essential for a diagnosis of LV. When LV is clinically suspected, a skin biopsy should be taken to confirm the diagnosis. Another critical step is to investigate the underlying associated conditions, such as connective tissue diseases, hypercoagulable states, thrombophilia, and malignancy. Unfortunately, no associated conditions can be detected in approximately 20% of all cases (idiopathic LV) despite all efforts. The diagnosis of the disease is delayed in most patients. Thus, irreversible, permanent scars appear. Early and appropriate treatment reduces pain and prevents the development of scars and other complications. Antiplatelet drugs and anticoagulants can be preferred as the first-line treatments along with general supportive measures. Other therapeutic options might be considered in unresponsive cases. Preference for refractory cases is based on availability, clinical experience, and patient-related factors (comorbidities, age, sex, and compliance). These include anabolic steroids, intravenous immunoglobulin, hyperbaric oxygen therapy, psoralen-ultraviolet A, vasodilators, fibrinolytics, immunomodulators, and immunosuppressives.

From dermatological conditions to COVID-19: Reasoning for anticoagulation, suppression of inflammation, and hyperbaric oxygen therapy

COVID‐19 generates a complex systemic inflammatory response that can lead to death due to wide macrophage activation, endothelial damage, and coagulation in critically ill patients. SARS‐CoV‐2‐induced lung injury due to inflammatory mediated thrombosis could be similar to the livedoid vasculopathy in the skin, supporting a translational comparison of these clinical settings. In this article, we discuss anticoagulation, suppression of inflammatory response, and hyperbaric oxygen therapy in the context of severe COVID‐19 and livedoid vasculopathy.

Livedoid vasculopathy: Clinical course and long-term outcome in Asian patients with a review of the literature

Livedoid vasculopathy (LV) is an uncommon, chronic, and recurrent thrombo-occlusive vascular disorder. Data specific to LV in Thai population remains scarce. This study aimed to evaluate the clinical course and treatment outcomes of LV in Thai patients, and to perform a literature review for studies that reported on anticoagulant treatment in LV. Seventy-four patients with a mean age of 37.6 ± 14.7 years were included. The female to male ratio was 5.2:1, and the median follow-up was 10.5 months. Most patients had primary LV disorder. Forty-eight patients were improved with treatments, with a median duration of 11.4 months. Combination treatments were commonly used, including anti-inflammatories, antiplatelets, and immunosuppressants. Add-on therapy with anticoagulant or psoralen plus ultraviolet-A (PUVA) led to disease improvement in a majority of the patients treated. Kaplan-Meier analysis demonstrated that 38.5%, 53.7%, and 57.9% would have disease improvement at 1, 2, and 3 years, respectively. Of 39 studies (n = 219) that reported on anticoagulant treatment in LV, anticoagulant drug was used as monotherapy in 104 patients. The mean duration of anticoagulant treatment was 7.2 ± 3.8 months, which led to disease improvement in 97 patients (93.3%). Bleeding side effect was found in 9 patients (8.7%). The highest incidence of LV was found among females aged 30 to 40 years. Combination therapy with anti-inflammatory drugs, antiplatelet drugs, and immunosuppressants led to disease improvement. The observed efficacy of add-on PUVA or anticoagulant is promising and should be further investigated. Further studies are needed to guide the development of an LV management guideline.

Livedoid Vasculopathy: diagnosis and treatment in pregnant women

Livedoid Vasculopathy is a disease characterized by occlusion of the capillaries of the dermis, without inflammatory signs. It begins with purpuric papules or macules that develop into painful ulcers, mainly involving the ankles and feet. In this case report, we describe diagnosis and treatment in a young pregnant patient, with excellent clinical response.
