Summary
Dermatologists evaluate vasculitis patients by examining skin manifestations and histopathology. This study investigates the link between vasculitis, particularly immune-complex-mediated types, and antiphospholipid antibodies, suggesting potential diagnostic insights.
Area of Science:
- Dermatology and Immunology
- Rheumatology
- Pathology
Background:
- Vasculitis encompasses various conditions affecting blood vessels, with dermatologists often managing small-vessel vasculitis and cutaneous polyarteritis nodosa (CPN).
- Cutaneous manifestations and histopathological findings are crucial for diagnosing vasculitis, including antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis and immune-complex-mediated vasculitis.
- Previous observations suggest a potential role for thrombosis in vasculitis pathogenesis, prompting investigation into its association with antiphospholipid antibodies.
Purpose of the Study:
- To characterize the initial cutaneous manifestations and histopathological findings in patients with vasculitis.
- To explore the association between vasculitis, specifically immune-complex-mediated vasculitis, and antiphospholipid antibodies.
- To investigate the potential role of specific antiphospholipid antibodies in the pathogenesis of Henoch-Schönlein purpura (HSP) and CPN.
Main Methods:
- Clinical examination of cutaneous manifestations in vasculitis patients.
- Histopathological assessment of skin biopsies, including examination for microvascular thrombus and leucocytoclastic vasculitis.
- Measurement of serum levels of antiphospholipid antibodies, such as IgA anticardiolipin antibody (aCL) and anti-phosphatidylserine-prothrombin complex antibodies.
Main Results:
- Histological examination of cryoglobulinaemic vasculitis revealed microvascular thrombus and leucocytoclastic vasculitis.
- Elevated serum levels of IgA anticardiolipin antibody (aCL) were observed in the active stage of adult HSP.
- A potential association between CPN and the presence of anti-phosphatidylserine-prothrombin complex antibodies was suggested.
Conclusions:
- Clinical and histopathological evaluation of cutaneous manifestations aids in refining vasculitis diagnostic strategies.
- Antiphospholipid antibodies, particularly IgA aCL, may play a role in the onset of adult HSP.
- CPN might be associated with anti-phosphatidylserine-prothrombin complex antibodies, warranting further investigation.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:11Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:28Inflammation: Introduction
Inflammation is a fundamental, protective biological response of vascularized tissues to cellular injury, infection, or harmful stimuli. Its primary function is to eliminate the initial cause of injury, clear necrotic cells and damaged tissue, and initiate the necessary repair processes.Cardinal SignsAcute inflammation presents with classic signs. Redness results from vasodilation and increased blood flow. Heat is due to increased metabolism and circulation. Swelling results from the...
