linear iga bullous dermatosis

Linear IgA bullous dermatosis (LABD) is a rare autoimmune blistering disease that may be triggered by some diseases and medications. For the latter one, non-steroidal anti-inflammatory drugs (NSAIDs) have been identified as one of the potential causative agents to develop LABD. Here, a rare case of drug-induced LABD is introduced. A 13-month-old Iranian boy presented with a history of generalized blisters, displaying the classic "string of pearls" sign who was eventually diagnosed as a case of LABD...

Adverse medication side effects are not uncommon in the inpatient setting, where polypharmacy is the norm. Linear IgA bullous dermatosis (LABD) can be a cutaneous side effect of commonly used inpatient medications, such as vancomycin. Symptoms of LABD can be severe, and proper recognition of this drug-induced disease is important to ensuring proper treatment, including the removal of the inciting agent. This report describes a case of vancomycin-associated LABD in a 66-year-old man and the proper management of drug-induced LABD...

Helicobacter pylori is a Gram-negative bacterium identified for the first time about 30 years ago and commonly considered as the main pathogenic factor of gastritis and peptic ulcer. Since then, it was found to be associated with several gastrointestinal and extra-gastrointestinal diseases. Helicobacter pylori is also associated with many skin disorders including, but not limited to, chronic urticaria, rosacea, lichen planus, atopic dermatitis, psoriasis, pemphigus vulgaris, vitiligo, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, primary cutaneous marginal zone B-cell lymphomas and cutaneous T-cell pseudolymphoma...

A 3-year-old boy presented with a 5-day history of bullous skin lesions localised mainly in the upper and lower limbs and in the genital region (figure 1). Lesions were not pruritic nor painful and showed a central crust. There was no family history of skin disorders or autoimmune diseases. The child never had fever and his physical examination was otherwise unremarkable. edpract;archdischild-2020-319179v1/BLKF1F1BLK_F1Figure 1Bullous skin lesions forming around a central crust, localised in the upper and lower limbs...

Pemphigus and pemphigoid diseases are organ-specific autoimmune diseases of the skin and/or mucous membranes, which are caused by autoantibodies targeting structural proteins of the skin. In other autoimmune diseases, a high prevalence of primary antibody deficiencies was noted. Conversely, a high prevalence of autoimmune diseases is reported in patients with primary antibody deficiencies. With the exception of one study, pointing toward a decrease of IgG in pemphigus patients, with a relative enrichment of IgG4, serum immunoglobulin (Ig) concentrations had not been studied in pemphigus and pemphigoid...

We report a case of linear IgA bullous dermatosis, a rare autoimmune blistering disorder that usually presents with the abrupt onset of tense bullae. We also emphasize the importance of direct immunofluorescence for the definitive diagnosis.

Neonatal autoimmune subepidermal blistering disease is rare. Mucosal involvement is more common in neonatal linear immunoglobulin A (IgA) bullous dermatosis. We describe a neonate with subepidermal cutaneous blistering disease with severe laryngeal and esophageal involvement leading to acute respiratory distress. Histopathology demonstrated a subepidermal blister with neutrophils and eosinophils at the dermal base. Collagen IV was detected at the dermal floor, and direct immunofluorescence showed linear IgG, IgA, and C3 deposits at the basement membrane zone...

Flame figures represent a characteristic but nondiagnostic histological finding in eosinophilic dermatoses. Some bullous autoimmune diseases with a predominant eosinophilic infiltrate, such as bullous pemphigoid, pemphigoid gestationis, and pemphigus vegetans, may show them. However, it is rare to find them in predominant neutrophilic bullous dermatoses such as linear immunoglobulin A. We present a 60-year-old man with a history of chronic urticaria, which presented a bullous disease after an acute parvovirus B19 infection...

Glycopeptides, such as vancomycin and teicoplanin, are primarily used in the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections, such as cellulitis, endocarditis, meningitis, pneumonia, and septicemia, and are some of the most commonly prescribed parenteral antimicrobials. Parenteral glycopeptides are first-line therapy for severe MRSA infections; however, oral vancomycin is used as a first-line treatment of Clostridioides difficile infections . Also, we currently have the longer-acting lipoglycopeptides, such as dalbavancin, oritavancin, and telavancin to our armamentarium for the treatment of MRSA infections...

Linear immunoglobulin A (IgA) bullous dermatosis (LABD) presents as a rare autoimmune disease that can either occur spontaneously or induced by certain drugs, the most common of which is vancomycin. LABD is a subepidermal blistering disease that is diagnosed by detecting linear IgA bands along the basement membrane. We present a case of a 59-year-old man with worsening blistering skin rash who was treated with vancomycin and piperacillin-tazobactam for pneumonia.

Linear IgA bullous dermatosis (LABD) is characterized by presence of multiple IgA autoantibodies, and a comparatively lesser number of IgG antibodies, directed against different hemidesmosomal antigens. The main autoantigens are LAD-1, LABD-97, BP180 and BP230, type VII collagen and laminin 332. We retrospectively studied the serology of 54 Italian patients with LABD using enzyme-linked immunosorbent assay (ELISA), immunoblotting assay, and indirect immunofluorescence on monkey oesophagus and salt-split skin...

Linear IgA dermatosis (LAD) is a rare autoimmune disorder in children. A 9-year-old boy was presented with blisters on the intact skin (face, body, arms, hands, soles, perigenital and perianal area) after amoxicillin treatment. Systemic corticosteroids and dapsone treatment for 6 weeks was successful. Clinical and immunofluorescence examinations are most important for differentiation of LAD and other drug-induced bullous dermatoses. They enable an early introduction of proper therapy.
