Drug-induced linear IgA bullous dermatosis after vancomycin discontinuance in a patient with renal insufficiency

A Case of Oral-Vancomycin-Induced Rash in a Patient with Acute Kidney Injury

Clostridioides difficile infection (CDI) is one of the most common hospital-acquired infections. Its incidence has increased during the last decade in the community among individuals with no previous risk factors; however, morbidity and mortality are still considered high in elderly patients. Oral Vancomycin and Fidaxomicin are the first lines of treatment for CDI. The systemic bioavailability of oral Vancomycin is thought to be undetectable due to its poor absorption in the gastrointestinal tract; therefore, routine monitoring is not warranted. Only 12 case reports were found in the literature that described adverse reactions associated with oral Vancomycin and its related risk factors. We present a case of a 66-year-old gentleman with severe CDI and acute renal failure who was started on oral Vancomycin upon admission. On day five of treatment, he developed leukocytosis associated with neutrophilia, eosinophilia, and atypical lymphocytes, with no evidence of active infection. Three days later, he developed a pruritic maculopapular rash in more than 50% of his body surface area. Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) was ruled out since the patient only had three inclusion criteria for this diagnosis. No clear inciting agent was found. Oral Vancomycin was stopped and supportive treatment was supplied for a presumed Vancomycin-induced allergic reaction. The patient had an excellent response, with complete resolution of the rash and leukocytosis in less than 48 h. By reporting this case, we want to raise awareness among clinicians to remember that, albeit rare, oral Vancomycin can be the cause of adverse drug reactions in patients with severe illnesses.

Ocular Manifestations and Management of Autoimmune Bullous Diseases

Autoimmune bullous diseases with ocular involvement consist of a group of systemic entities that are characterized by formation of autoantibodies against the proteins of the epithelial basement membrane zone of the conjunctiva. Mostly, the elderly are affected by these diseases. The characteristic patterns of mucocutaneous involvement and the specific tissue components targeted by these autoantibodies are differentiating features of these diseases. Ocular pemphigus vulgaris exhibits intraepithelial activity, whereas the autoimmune activity in linear immunoglobulin A disease, mucous membrane pemphigoid, and epidermolysis bullosa acquisita occurs at a subepithelial location. Given the increased risk for blindness with delays in diagnosis and management, early detection of ocular manifestations in these diseases is vital. The precise diagnosis of these autoimmune blistering diseases, which is essential for proper treatment, is based on clinical, histological, and immunological evaluation. Management usually includes anti-inflammatory and immunosuppressive medications. Inappropriate treatment results in high morbidity and even potential mortality.

Drug-induced linear immunoglobulin A bullous dermatosis: A French retrospective pharmacovigilance study of 69 cases

AIMS

Linear immunoglobin A (IgA) bullous dermatosis is a rare autoimmune dermatosis considered spontaneous or drug-induced (DILAD). We assessed all DILAD cases, determined the imputability score of drugs and highlighted suspected drugs.

METHODS

Data for patients with DILAD were collected retrospectively from the French Pharmacovigilance network (from 1985 to 2017) and from physicians involved in the Bullous Diseases French Study Group and the French Investigators for Skin Adverse Reactions to Drugs. Drug causality was systematically determined by the French imputability method.

RESULTS

Of the 69 patients, 42% had mucous membrane involvement, 20% lesions mimicking toxic epidermal necrolysis (TEN), 21% eosinophil infiltrates and 10% keratinocytes necrosis. Direct immunofluorescence, in 80%, showed isolated linear IgA deposits. Vancomycin (VCM) was suspected in 39 cases (57%), 11 had TEN-like lesions, as compared with three without VCM suspected. Among the 33 patients with a single suspected drug, 85% had an intrinsic imputability score of I4. Among them, enoxaparin, minocycline and vibramycin were previously unpublished. For all patients, the suspect drug was withdrawn; 15 did not receive any treatment. First-line therapy for 31 patients was topical steroids. Among the 60 patients with available follow-up, 52 achieved remission, 10 without treatment. Four patients experienced relapse, four died and five had positive accidental rechallenges.

CONCLUSIONS

There is no major clinical difference between DILAD and idiopathic linear IgA bullous dermatosis, but the former features a higher prevalence of patients mimicking TEN. VCM, suspected in more than half of the cases, might be responsible for more severe clinical presentations. We report three new putative drugs.

Thyroid diseases and skin autoimmunity

The skin is the largest organ of the body, at the boundary with the outside environment. Primarily, it provides a physical and chemical barrier against external insults, but it can act also as immune organ because it contains a whole host of immune-competent cells of both the innate and the adaptive immune systems, which cooperate in eliminating invading pathogens following tissue injury. On the other hand, improper skin immune responses lead to autoimmune skin diseases (AISD), such as pemphigus, bullous pemphigoid, vitiligo, and alopecia. Although the interplay among genetic, epigenetic, and environmental factors has been shown to play a major role in AISD etiology and progression, the molecular mechanisms underlying disease development are far from being fully elucidated. In this context, epidemiological studies aimed at defining the association of different AISD with other autoimmune pathologies revealed possible shared molecular mechanism(s) responsible for disease progression. In particular, over the last decades, a number of reports have highlighted a significant association between thyroid diseases (TD), mainly autoimmune ones (AITD), and AISD. Here, we will recapitulate the epidemiology, clinical manifestations, and pathogenesis of the main AISD, and we will summarize the epidemiological evidence showing the associations with TD as well as possible molecular mechanism(s) underlying TD and AISD pathological manifestations.

Vancomycin-associated linear IgA disease mimicking toxic epidermal necrolysis

Linear IgA dermatosis is a rare subepidermal autoimmune blistering disease characterized by linear deposition of IgA along the basement membrane zone. In the last three decades, many different drugs have been associated with the drug-induced form of the disease, especially vancomycin. We report a case of vancomycin-induced linear IgA disease mimicking toxic epidermal necrolysis. The aim of this work is to emphasize the need to include this differential diagnosis in cases of epidermal detachment and to review the literature on the subject and this specific clinical presentation.

A Rare Case of Vancomycin-Induced Linear Immunoglobulin A Bullous Dermatosis

Linear IgA bullous dermatosis (LABD) is an autoimmune vesiculobullous disease, which is typically idiopathic but can also rarely be caused by medications or infections. Vancomycin is the most common drug associated with LABD. Lesions typically appear 24 hours to 15 days after the first dose of vancomycin. It is best characterized pathologically by subepidermal bulla (blister) formation with linear IgA deposition at the dermoepidermal junction. Here we report an 86-year-old male with a history of left knee osteoarthritis who underwent a left knee arthroplasty and subsequently developed a prosthetic joint infection. This infection was treated with intravenous vancomycin as well as placement of a vancomycin impregnated joint spacer. Five days following initiation of antibiotic therapy, he presented with a vesiculobullous eruption on an erythematous base over his trunk, extremities, and oral mucosa. The eruption resolved completely when intravenous vancomycin was discontinued and colchicine treatment was begun. Curiously, complete resolution occurred despite the presence of the vancomycin containing joint spacer. The diagnosis of vancomycin-induced linear IgA bullous dermatosis was made based on characteristic clinical and histopathologic presentations.

Bullous Dermatosis in an End-Stage Renal Disease Patient: A Case Report and Literature Review

Patients with advanced chronic kidney disease including ESRD patients may present with a wide spectrum of cutaneous abnormalities, ranging from xerosis to hyperpigmentation to severe deforming necrotizing lesions. Skin problems are not uncommon in this population of patients, with a clinical presentation that can be quite bizarre, mandating a long list of differential diagnostic possibilities, and subsequent rise of a puzzling diagnostic challenge. We describe an ESRD patient who presented with blistering, nonhealing ulcerative lesions with a diagnostic skin biopsy revealing a mixed pattern of linear IgA bullous dermatosis and dermatitis herpetiformis. A clinical remission could be achieved with pulse intravenous steroids followed by oral maintenance in combination with dapsone, with no evidence of recurrence.

Immune-mediated reactions to vancomycin: A systematic case review and analysis

BACKGROUND

Vancomycin is a broad-spectrum antibiotic whose use may be limited by adverse drug reactions (ADRs). Although vancomycin toxic effects are known, there are limited data on vancomycin hypersensitivity reactions (HSRs).

OBJECTIVE

To understand the most commonly reported vancomycin HSRs through systematic case review.

METHODS

We performed a literature search for English-language case reports and series from 1982 through 2015 (last search July 31, 2015) on Ovid MEDLINE and PubMed. The search included the subject heading vancomycin with the subheading adverse effects and separate text searches for vancomycin with a list of specified HSRs. References of identified articles were reviewed to find additional articles. Clinical data were collected and summarized.

RESULTS

Of 201 identified articles, 84 were screened and 57 fully assessed; these 57 articles contained 71 vancomycin HSR cases that were included in analysis. Vancomycin HSRs were immediate (anaphylaxis, n = 7) and nonimmediate (n = 64). Nonimmediate HSRs included linear IgA bullous dermatosis (LABD, n = 34), drug rash eosinophilia and systemic symptoms (DRESS) syndrome (n = 16), acute interstitial nephritis (AIN, n = 8), and Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN, n = 6). Median times of vancomycin therapy before HSR onset was 7 days (interquartile range [IQR], 4-10 days) for LABD, 9 days (IQR, 9-22 days) for SJS/TEN, 21 days (IQR, 17-28 days) for DRESS syndrome, and 26 days (IQR, 7-29 days) for AIN. Overall, 11 patients (16%) died, and 4 (6%) had deaths attributed to the HSR.

CONCLUSION

Vancomycin causes a variety of HSRs; the most commonly identified were nonimmediate HSRs, with LABD being most frequent. We observed a high frequency of HSR mortality. Further data are needed to understand the frequency and severity of vancomycin HSRs.

Vancomycin revisited - 60 years later

Vancomycin is one of the older antibiotics that has been now in clinical use close to 60 years. Earlier on, vancomycin was associated with many side effects including vestibular and renal, most likely due to impurities contained in early vancomycin lots. Over the years, the impurities have been removed and the compound has now far less vestibular adverse effects, but still possesses renal toxicity if administered at higher doses rendering trough serum levels of >15 mcg/mL or if administered for prolonged periods of time. Vancomycin is effective against most Gram-positive cocci and bacilli with the exception of rare organisms as well as enterococci that became vancomycin resistant, mostly Enterococcus faecium. The major use of vancomycin today is for infections caused by methicillin-resistant Staphylococcus aureus (MRSA), methicillin-resistant Staphylococcus epidermidis (MRSE) and amoxicillin-resistant enterococci. In its oral form, vancomycin is used to treat diarrhea caused by Clsotridium difficile. With S. aureus, there are only a handful of vancomycin-resistant strains. Nevertheless, a "vancomycin creep" that is slow upward trending of vancomycin MIC from <1 mcg/mL to higher values has been noted in several parts of the world, but not globally, and strains that have MIC's of 1.5-2 mcg/mL are associated with high therapeutic failure rates. This phenomenon has also been recently recognized in methicillin-susceptible S. aureus (MSSA). While vancomycin is relatively a safe agent adverse events include the "red man" syndrome, allergic reactions, and various bone marrow effects as well as nephrotoxicity. Vancomycin has been a very important tool in our therapeutic armamentarium that remained effective for many years, it is likely remain effective as long as resistance to vancomycin remains controlled.

Drug-Induced Linear IgA Bullous Dermatosis

We report the case of a 69-year-old Japanese woman with multiple blistering lesions covering almost her whole body. Linear IgA and C3 depositions were seen at the basement membrane zone on direct immunofluorescence (IF). Linear IgA bullous dermatosis (LABD) is one of the autoimmune diseases resulting in subepidermal blisters. It is clinically similar to bullous pemphigoid and IF is required to distinguish the two diseases. In this case, the blistering lesions appeared after vancomycin treatment. This drug was strongly suspected as a cause of LABD in light of the clinical course of the patient even though a drug-lymphocyte stimulating test was negative. Among the various implicated causative drugs, vancomycin is the most commonly associated with LABD.

Linear IgA bullous disease presenting as toxic epidermal necrolysis: a case report and review of the literature

A 91-year-old female presented with widespread skin sloughing and bullae clinically mimicking toxic epidermal necrolysis (TEN). The patient was on multiple antibiotics, including vancomycin and piperacillin/tazobactam. Histopathology and direct immunofluorescence were consistent with a diagnosis of linear IgA bullous disease (LABD). In a PubMed review of the literature from 1975 to the present, there have been 15 cases of LABD presenting as TEN clinically and with characteristic linear IgA deposits on direct immunofluorescence studies. Vancomycin and phenytoin were the most commonly implicated medications. Twelve patients saw a resolution or healing of skin lesions after discontinuation of the implicated medication. There were, however, 5 patients who died of complications related to their comorbidities. It is important to include LABD in the differential diagnosis when evaluating patients who clinically present with TEN.

Linear IgA bullous dermatosis: a rare side effect of vancomycin

Following a motor vehicle accident, a 70-year-old white female was admitted with lower limb fractures that required operative repair. The postoperative course was complicated by sepsis. Vancomycin and piperacillin/tazobactam were initiated empirically. Five days later, she developed a pruritic maculopapular rash in the groin and axilla. The rash progressed to a non-hemorrhagic vesicles and bullae on an erythematous base and spread to involve the trunk, palms and the inner aspects of the lips. Skin biopsy and direct immunofluorescence testing were consistent with vancomycin-induced linear IgA bullous dermatosis. Vancomycin was stopped with complete resolution of the lesions in the subsequent 2 weeks. Being aware of vancomycin-induced linear IgA bullous dermatosis in patients who develop a blistering skin rash while receiving this antibiotic should lead to timely interventions. Stopping vancomycin promptly and encouraging early skin biopsy to confirm the diagnosis will prevent disease progression and avoid unnecessary costs and suffering.

Drug-induced linear IgA bullous dermatosis after discontinuation of cefuroxime axetil treatment

BACKGROUND

Linear immunoglobulin A (IgA) bullous dermatosis (LABD) is a rare autoimmune blistering disorder. The disease may be either idiopathic or druginduced. Over the past 30 years, approximately one hundred LABD cases have been described as induced by a wide range of drugs, chiefly antibiotics.

MAIN OBSERVATIONS

We report the case of 37-year-old woman who developed pruritic bullous lesions spread all over the body three weeks after her last dose of cefuroxime axetil. Antibiotic therapy was started due to rhino-sinusitis.

CONCLUSIONS

In most reported cases of drug-induced LABD, skin lesions occur within the time of drug administration. However, the onset of disease may be even after discontinuation of treatment. It seems that in such cases, other clinical conditions (like infection) act, as cofactors of immunologic response.

Linear immunoglobulin A bullous dermatosis

Linear immunoglobulin A (IgA) bullous dermatosis, also known as linear IgA disease, is an autoimmune mucocutaneous disorder characterized by subepithelial bullae, with IgA autoantibodies directed against several different antigens in the basement membrane zone. Its immunopathologic characteristic resides in the presence of a continuous linear IgA deposit along the basement membrane zone, which is clearly visible on direct immunofluorescence. This disorder shows different clinical features and distribution when adult-onset of linear IgA disease is compared with childhood-onset. Diagnosis is achieved via clinical, histopathologic, and immunopathologic examinations. Two common therapies are dapsone and sulfapyridine, which reduce the inflammatory response and achieve disease remission in a variable period of time.

Ocular manifestations of blistering diseases

Ocular manifestations are a comorbidity of a group of chronic autoimmune blistering diseases that includes mucous membrane pemphigoid, linear immunoglobulin A disease, epidermolysis bullosa acquisita, and ocular pemphigus vulgaris. Various diagnostic measures differentiate between the diseases and allow for appropriate treatment including a specific selection of immunomodulatory medications. New treatment modalities offer alternatives that may minimize disease severity and residual tissue damage and may reduce treatment-related complications.

[Cutaneous drug reactions induced by glycopeptides]

Glycopeptides are a class of antibiotics used with a rising frequency because of the increasing number of infections due to Methicillin-resistant staphylococci. The dermatological adverse effect of vancomycin are well-known: "red man syndrome", maculopapular exanthema, etc., with some distinctive features such as Ig A linear dermatosis. Drug eruptions are less common but not insignificant when using teicoplanin, a more recent molecule. A given glycopeptide cannot be considered as an alternative for every patient "allergic" to another, because of cases of cross-reaction and the morbi-mortality of some cutaneous drug reactions. This emphasizes the importance to recognize early clinical signs. In this article, we review the various dermatological adverse drug reactions induced by glycopeptides, and suggest a possible management to clinicians who could be confronted with this problem.

Bullous dermatosis associated with gemcitabine therapy for non-small-cell lung carcinoma

Gemcitabine considered is to be a well-tolerated cytostatic drug with little known side effects. Cutaneous reactions are well known but still rarely reported. We report the case of a 75-year-old man with stage IV non-small-cell lung carcinoma treated with combination of gemcitabine 1000 mg/m2 and cisplatin 75 mg/m2 repeated every 28 days, who developed bilateral cutaneous bullous lesions of lower limbs following gemcitabine administration. Histopathologic examination did not show any toxidermy aspect and there was not any sign of immunoglobulin deposit in direct immunofluorescence test. Chemotherapy was stopped and lesions disappeared without any treatment. Even delayed with regard to gemcitabine administration, the causal relationship of gemcitabine treatment with skin reaction is possible according to the Naranjo probability scale. Pathologists should be aware of this kind of side effect in managing chemotherapy drugs and report any dermatologic reactions in order to identify the cause of toxicity and avoid a misdiagnosis.

Vancomycin-induced linear IgA bullous disease presenting as toxic epidermal necrolysis

Linear IgA bullous dermatosis (LABD) is a rare autoimmune vesiculobullous disorder characterized by variable clinical presentations that may mimic bullous pemphigoid, dermatitis herpetiformis, cicatricial pemphigoid and erythema multiforme. A few cases of drug-induced LABD that clinically resembled toxic epidermal necrolysis (TEN) have been reported. A subset of patients with LABD have been found to be drug-induced; the most common drug being vancomycin. The diagnosis of LABD is confirmed by the presence of a linear band of IgA along the basement membrane zone on direct immunofluorescence microscopy. We report a case of a 77-year-old man who presented to us with vancomycin-induced LABD that presented clinically as TEN. He had a complete recovery over a 3-week period following discontinuation of the vancomycin and the addition of oral dapsone therapy. It is important to be aware that drug-induced LABD can mimic TEN.

Localized linear IgA disease induced by ampicillin/sulbactam

We describe a patient who developed an exclusively perianal-intergluteal vesicular eruption after receiving a course of ampicillin/sulbactam. Direct immunofluorescence microscopy of perilesional skin demonstrated linear deposits of IgA along the dermal-epidermal junction. Circulating IgA autoantibodies against the 120-kd soluble ectodomain of bullous pemphigoid antigen 180 (LAD-1 autoantigen) were detected by immunoblotting. Discontinuation of the antibiotics resulted in a rapid resolution of the skin lesions. This is a most unusual case of localized drug-induced linear IgA disease.

The miscellaneous blistering disorders

Historically, the classification of the blistering disorders has been arbitrarily assigned by common clinical features (ie, vesicle, bullae), etiologic factors (ie, infectious, immunologic), or histologic parameters (ie, intraepidermal and subepidermal). There are distinct advantages to each of these classification systems, yet there remain a small number of either common conditions that rarely manifests as a blistering disorder or uncommon conditions that routinely blister, defying conventional classification. Such misfits comprise a miscellaneous group of blistering conditions that merit special consideration.

Vancomycin-associated linear IgA bullous dermatosis mimicking toxic epidermal necrolysis

Vancomycin is the most frequent trigger of drug-induced linear IgA bullous dermatosis. We describe a fulminant case of linear IgA bullous dermatosis in a 74-year-old man who experienced skin sloughing of 90% of his body surface after receiving vancomycin.

Linear IgA dermatosis induced by a new angiotensin-converting enzyme inhibitor

A 68-year-old female patient treated with benazepril for arterial hypertension developed oral and cutaneous blistering. Biopsy of the oral and cutaneous lesions showed neutrophilic microabscesses in the mesenchymal papillae, with epitheliomesenchymal separation. Direct immunofluorescence revealed linear immunoglobulin deposits at the epithelial basement membrane zone, consisting predominantly of IgA. The histologic results supported the clinical diagnosis of drug-induced linear IgA disease. The substitution of benazepril with a beta blocker resulted in complete resolution of all mucocutaneous lesions.

Gender differences in vesiculobullous autoimmune skin diseases

Autoimmune vesiculobullous skin diseases are a common occurrence in dermatology practice and do have gender differences. While most dermal antigens and autoantibodies in these diseases have been identified, the etiology and clinical characteristics of the autoimmunity remain obscure, such as why more than 70% of autoimmune diseases are more frequent in women. Researching gender differences and the mechanisms of autoimmune diseases will shed light on the answers to such questions.

Bullous skin disease: an unusual allergic reaction to vancomycin

Severe reactions due to vancomycin are uncommon. We describe a case of vancomycin-induced linear immunoglobulin A bullous disease and review the literature pertinent to this entity. This is a rare subepidermal blistering disorder, with a heterogenous clinical presentation. It is characterized by IgA deposition in a linear pattern along the basement membrane zone. It seems to be autoantibody-mediated and is not dose-dependent. Spontaneous and complete skin healing follows vancomycin withdrawal; rechallenge reproduces the disease with a more rapid and severe onset. Because vancomycin is almost never suspected to be the cause of such manifestations, awareness of this rare autoimmune reaction is crucial. Early diagnosis through direct immunofluorescence of the perilesional skin would avoid unnecessary laboratory investigations and therapeutic measures and would shorten significantly the pain and suffering of these patients.

Vancomycin-induced linear IgA disease with autoantibodies to BP180 and LAD285

Linear IgA disease (LAD) is an acquired autoimmune subepidermal bullous disease characterized by the linear deposition of IgA at the basement membrane zone. A minority of cases are induced by drugs, of which the most frequently implicated is vancomycin. The target antigens in idiopathic LAD are heterogeneous, but have not previously been reported in vancomycin-induced LAD. We report three cases, and in two of these we investigated the target antigens. In both we identified IgA antibodies to LAD285 and IgA and IgG antibodies (dual response) to BP180.
