Abstract
BACKGROUND Levamisole has recently been implicated as a cause of cutaneous vasculopathy in cocaine abusers. The objective of this study was to describe this relatively new entity by reviewing published cases identified through a literature search. METHODS Published reports identified through a search of PubMed database (from 1964 to November 2011) were reviewed to record clinical, serological and pathologic findings. RESULTS A cohort of 32 patients had a mean age of 44 ± 9 years with a female predominance (75%). Rash predominately affected lower extremities (87.5%), followed by face (78%) and ears (69%) and typically presented as purpuric plaques, which were seen in a retiform pattern in 16 (50%) and had central necrosis in 11 patients (34%). Leukopenia and neutropenia were found in 20 patients (63%). Antinuclear cytoplasmic antibody (ANCA) was positive in 30 patients (94%); p-ANCA in 28 patients (87.5%), c-ANCA in 19 (59%) and both in 17 patients (53%). Skin biopsy results were available for 29 patients: 14 (48%) had pure thrombotic vasculopathy, 4 (14%) had pure small vessel vasculitis and 11 (38%) had evidence of both. Treatment information was available for 30 patients. Only supportive care was given to 11 patients (37%), steroids to 16 (53%) and surgical treatment for 5 (17%). Clinical course of lesions was available for 24 patients. Rash resolved in 11 patients (46%) and improved in 13 (54%). During median follow-up of 21 days (range, 7-270 days), 10 of 22 patients had recurrences related to cocaine use. CONCLUSION Levamisole-induced cutaneous vasculopathy in cocaine users is characterized by a female predominance, a retiform purpuric rash with a predilection for lower extremities, autoantibody production, leukopenia and/or neutropenia and recurrences with future cocaine use.

Abstract
A rare case of a patient with an unusual skin rash after using cocaine is presented. A clinical diagnosis of levamisole-induced vasculitis was made based on initial presentation of purpuric skin lesions involving the ears and positive cocaine on urine toxicology screening. The diagnosis was confirmed after laboratory findings of neutropenia, positive serum levamisole, and a histopathologic test of the skin lesions. The pathophysiology of this condition is discussed. Treatment with methylprednisolone and prednisone led to the resolution of the neutropenia and complete recovery of the skin lesions. With the growing use of levamisole-tainted cocaine, clinicians should be aware of the symptoms of vasculitis and neutropenia induced by this combination of drugs to avoid unnecessary tests and delayed diagnosis.

Abstract
We report a case of cutaneous vasculopathy associated with the use of levamisole-adulterated cocaine. This recently described clinical entity is characterized by a purpuric rash with a predilection for the ears, leukopenia, and anti-neutrophilic cytoplasmic antibody (ANCA) positivity. It is estimated that more than 70% of the current United States cocaine supply is contaminated with levamisole. Levamisole is a widely available, inexpensive, white powder used as a "cutting agent" in cocaine to expand volume and increase profits. It may also increase the euphoric and stimulatory effects of cocaine by increasing brain dopamine levels and producing amphetamine-like metabolites. Our patient exhibited a characteristic rash with involvement of the ears, leukopenia, and cocaine metabolites were detected in serum and urine. The presence of levamisole was confirmed in the urine utilizing gas chromatography-mass spectrometry. ANCA positivity was also present. Punch biopsy of the skin demonstrated vascular thrombosis and necrosis without true vasculitis. We review the literature for reported cases of cocaine-levamisole cutaneous vasculopathy syndrome, highlight the salient immunologic abnormalities, and contrast the features of this entity with idiopathic systemic vasculitis.

Abstract
The prevalence of cocaine-induced pseudovasculitis (CIP) causing cutaneous destruction is increasing, and plastic surgeons need to be aware of this condition because they are a part of the multidisciplinary treatment team. Differentiation of CIP from a true autoimmune vasculitis can be exceedingly challenging, and misdiagnosis with ensuing treatment may be fatal. This article is a succinct review of CIP, guided by a clinical case of 30% total body surface area skin necrosis, to familiarize the reader with this syndrome. Diagnostic aids include history of cocaine use, localized disease manifestation to skin or mucosa, discordance of antineutrophil cytoplasmic antibody and target antibody patterns typical for true vasculitis, and testing for antihuman neutrophil elastase and levamisole. Treatment is primarily supportive, and wound care, with regard to dressings and surgery, is a cross between to that of burns and meningococcemia patients.

Abstract
Systemic complications of levamisole-adulterated cocaine (LAC) use have recently been described. The objective of this review is to increase awareness of these manifestations among oral and maxillofacial surgeons. LAC exposure through inhalation, nasal insufflation, or injection can induce cutaneous vasculopathy and hematologic abnormalities such as neutropenia or agranulocytosis. Unlike other vasculopathies involving the skin, LAC-induced vascular injury frequently manifests with purpuric and necrotic lesions that involve the face and ears. Oral manifestations have also been reported but are not yet well characterized. The aforementioned hematologic manifestations are not uncommon, and patients exposed to LAC are potentially at higher risk for infectious complications. When manifestations of LAC affect the head, neck, and oral cavity, oral and maxillofacial surgeons may be the first providers to encounter the patient. Early recognition of the clinical signs and laboratory abnormalities will better allow for distinguishing LAC-related effects from various clinical mimics, will facilitate appropriate patient management, and may further contribute to the understanding of the biological effects of LAC.

Abstract
A 2010 US report recently detected the presence of levamisole in greater than 77 % of seized cocaine samples. A syndrome of retiform purpura, often involving ears and flanks, with vasculopathy or vasculitis on biopsy, associated with anti-nuclear cytoplasmic antibodies as well as antiphospholipid antibodies, previously associated with therapeutic use of levamisole has now re-emerged, and is associated with cocaine adulterated with levamisole. Patients with this unusual constellation of signs and laboratory findings should be questioned about exposure to cocaine.

Abstract
The complex and fascinating spectrum of inflammatory skin disease, and the comprehension of it, is ever expanding and evolving. During the first decade of the 21st century, numerous advances in the understanding of inflammatory disease mechanisms have occurred, particularly in psoriasis and atopic dermatitis. Continuation of this trend will assure a future in which molecular tests for biomarkers of immediate clinical relevance are used in routine patient care, not only for diagnosis but also for prognosis and management. This article focuses on selected recent or noteworthy developments that are clinically relevant for the histologic diagnosis of inflammatory skin diseases.

Abstract
Although cocaine-induced pseudovasculitis and urticarial vasculitis have been reported in the past, levamisole-induced vasculopathy with ecchymosis and necrosis, termed here LIVEN, has only recently been described in association with cocaine use. Levamisole, a veterinary antihelminthic agent used previously as an immunomodulating agent, is present as a "cutting agent" in approximately two-thirds of the cocaine currently entering the United States. Levamisole is believed to potentiate the effects of cocaine and may also be used as a "signature" for tracing its market distribution. Herein, we report 2 cases of LIVEN in patients with histories of chronic cocaine use. In both the cases, a temporal association with neutropenia preceding the eruption was noted. A novel histopathologic finding present only in the second case was the presence of extensive interstitial and perivascular neovascularization. Our 2 cases reaffirm that neutropenia may precede the cutaneous eruption of LIVEN. Case 2 extends the spectrum of histopathologic findings to include the novel phenomenon of neovascularization-hitherto unreported in this entity.

Abstract
OBJECTIVES To report 4 cases of cocaine-related purpura and to review previously reported cases of levamisole, levamisole-contaminated cocaine, and cocaine-induced vasculopathy. METHODS We describe 4 patients suspected of vasculopathy associated with levamisole-tainted cocaine use. A retrospective review of the literature was performed using the PubMed, PubJet, MD consult, and Cochrane review databases. RESULTS Four cases (2 females and 2 males), 46 to 55 years of age, presented with cocaine-related purpura, mainly affecting the ears, neutropenia, and autoantibodies. Skin biopsies revealed a mixed pattern of leukocytoclastic vasculitis and microvascular thrombosis in 2 cases, and pure thrombosis in the third case. The mixed vasculopathic pattern in association with neutropenia, both known adverse effects of levamisole, and levamisole positivity in 2 cases point to this compound as the true etiologic agent in our patients. Eleven cases of levamisole-contaminated cocaine-induced vasculopathy have been described in the English literature. Among these, 10 were females. Age range was 22 to 57 years. Urine levamisole positivity was tested and confirmed in 3 of the 11 cases. The clinical characteristics, laboratory features, histology, treatment, and recovery rates were compared for the published cases of levamisole, levamisole-contaminated cocaine, and cocaine-induced vasculopathy. CONCLUSIONS Adulterated cocaine abuse is an increasingly recognized phenomenon in North America. Levamisole is among the many contaminants that have been detected in seized cocaine throughout North America and Europe. Recent reports described an association between levamisole-tainted cocaine and purpuric skin rash, neutropenia, and the presence of autoantibodies.

Abstract
We present three cases describing the various skin manifestations of presumed levamisole-contaminated cocaine use. Antibody-mediated vasculitis and neutropenia were consistent findings in these cases and repeat exposure resulted in distinct dermatologic complications. This phenomenon of levamisole-induced vasculitis and neutropenia is being increasingly described and has characteristic wound manifestations that must be recognised and treated early.

Abstract
This represents the largest case of skin necrosis related to levamisole, a common cocaine contaminant, requiring closure with skin grafts, and is the only case resulting in nasal amputation, central upper lip excision, extremity bone necrosis, and above knee amputation. The case report is followed by a review of the literature. Unique considerations for the full-thickness necrosis induced by levamisole vasculitis are highlighted, including antibody level monitoring, need for multiple excisions, timing of skin grafting, and potential for soft tissue and bone necrosis as well. A 54-year-old man presented to an outside facility with fever, generalized weakness, and agranulocytosis, with a history of cocaine use 3 weeks before. After admission, he developed generalized violaceous lesions and an elevated p-antineutrophilic cytoplasmic antibody and was diagnosed with disseminated vasculitis and agranulocytosis secondary to levamisole-contaminated cocaine exposure. On transfer to the authors' facility, 52% TBSA was involved with violaceous, nonblanching lesions, which progressed to full-thickness necrosis. Local wound care continued until necrotic areas fully demarcated and progressive necrosis stabilized, and skin grafting for closure was not performed until antibody levels normalized. Current treatment of levamisole-induced skin rash or necrosis focuses on discontinuation of levamisole. As demonstrated by this case, extensive necrosis secondary to levamisole-induced vasculitis can be successfully treated with multiple excisions until necrosis stabilizes, and then, split-thickness autografts may be applied. In areas with poor vascular supply or areas with poor functional prognosis, amputation may ultimately be required.

Abstract
The objective of this study was to describe a novel presentation of peripheral vasculitis associated with levamisole-adulterated cocaine. Cocaine abuse is widespread in the United States with 5.3 million people using cocaine in 2008. Over the past decade, drug enforcement officials have noticed the presence of levamisole in confiscated cocaine samples as an adulterant. Known side effects of cocaine-related levamisole ingestion have included agranulocytosis and a cutaneous acral purpura that is histopathologically characterized by a mixture of inflammation (vasculitis) and occlusion (vasculopathy). A 54-year-old man who nasally ingested cocaine laced with levamisole developed widespread necrotic/purpuric skin lesions on approximately 20% of his body with an acral accentuation. These lesions were complicated by multiple areas of sloughing and necrosis. He was initially treated with topical silver sulfadiazine dressing changes but progressed to require debridement and split-thickness skin grafting. Peripheral vasculitis/vasculopathy with severe necrosis resembling Coumadin necrosis is a relatively recently recognized sequelae from levamisole-adulterated cocaine use.

Abstract
Levamisole is a pharmaceutical with anthelminthic and immunomodulatory properties that was previously used in both animals and humans to treat inflammatory conditions and cancer. Levamisole has been identified as a cocaine adulterant in the United States since 2003. By 2009, the United States Drug Enforcement Administration (DEA) estimated that 69% of the cocaine seized contained levamisole. The first case reports of complications related to levamisole in cocaine users were published in 2009. The objectives of this article are to review the literature regarding the full spectrum of possible complications related to levamisole use for medical purposes, to review the current scope of levamisole-induced complications in cocaine users and to discuss the pharmacological properties that might explain the motivation behind the large-scale adulteration of cocaine with levamisole. Literature review revealed that significant complications were quickly reported when levamisole was used in inflammatory conditions. By 1976, several cases of leukopenia and agranulocytosis were reported. Recurrence with re-exposure was well described and agranulocytosis spontaneously reversed upon discontinuation of therapy. Vasculitis secondary to levamisole treatment was first reported in 1978 and mostly manifests as leukocytoclastic vasculitis, cutaneous necrotising vasculitis and thrombotic vasculopathy without vasculitis. These findings typically, but not invariably, involve the ear lobes. Discontinuation of levamisole therapy was again a critical part of the treatment. Various neurological side effects were described with levamisole therapy, the most concerning complication being multifocal inflammatory leukoencephalopathy (MIL). Literature review identified 203 unique cases of complications in cocaine users that can be attributed to levamisole adulteration. The two principal complications reported are haematological (140 cases of neutropenia) and dermatological (84 cases). Even though these complications can occur in isolation, many cases displayed both simultaneously. No formal case of leukoencephalopathy in the setting of cocaine use has been reported so far. A striking phenomenon is the apparent high level of recurrence (27.1%) of symptoms in cocaine users after re-exposure to cocaine that is presumably adulterated. The importance of accurately identifying levamisole-induced complications is therefore critical for symptomatic patients as discontinuation of exposure is fundamental and as a correct diagnosis prevents unnecessary and potentially dangerous use of other treatment modalities like powerful immunosuppressive therapy. Literature review suggests that levamisole might have the advantages of enhancing noradrenergic neurotransmission by inhibiting reuptake, by inhibiting MAO and/or COMT, by acting on ganglionic nicotinic receptors and by being partially metabolized into an amphetamine-like compound. It could also increase endogenous opioids and increase dopamine concentration in the cerebral reward pathway. These potential effects make levamisole an interesting choice as a cocaine adulterant. It seems unlikely that levamisole use as a cocaine adulterant will soon reach an end. More information is needed about the diagnosis and treatment of levamisole-induced complications, and the efforts of the medical and public health community is needed to face this challenging problem.

Abstract
The United States Public Health Service Administration is alerting medical professionals that a substantial percentage of cocaine imported into the United States is adulterated with levamisole, a veterinary pharmaceutical that can cause blood cell disorders such as severe neutropenia and agranulocytosis. Levamisole was previously approved in combination with fluorouracil for the treatment of colon cancer; however, the drug was withdrawn from the U.S. market in 2000 because of the frequent occurrence of agranulocytosis. The detection of autoantibodies such as antithrombin (lupus anticoagulant) and an increased risk of agranulocytosis in patients carrying the human leukocyte antigen B27 genotype suggest that toxicity is immune-mediated. In this perspective, we provide an historical account of the levamisole/cocaine story as it first surfaced in 2008, including a succinct review of levamisole pharmacology, pharmacokinetics, and preclinical/clinical evidence for levamisole-induced agranulocytosis. Based on the available information on levamisole metabolism in humans, we propose that reactive metabolite formation is the rate-limiting step in the etiology of agranulocytosis associated with levamisole, in a manner similar to other drugs (e.g., propylthiouracil, methimazole, captopril, etc.) associated with blood dyscrasias. Finally, considering the toxicity associated with levamisole, we propose that the 2,3,5,6-tetrahydroimidazo[2,1-b]thiazole scaffold found in levamisole be categorized as a new structural alert, which is to be avoided in drug design.

Abstract
PURPOSE OF REVIEW Most of the illicit cocaine consumed in the United States and elsewhere is contaminated with levamisole, a veterinary medication. Agranulocytosis caused by levamisole exposure through cocaine abuse was first described in 2009. Since then, levamisole has also been shown and is known to cause vascular and neurologic complications. In this review, we provide an overview of the medical consequences of exposure to levamisole from adulterated cocaine. RECENT FINDINGS Within the past year, several new case series have deepened our understanding of the levamisole-agranulocytosis vasculopathy syndrome. The common nature of this exposure has been delineated, cocaine contaminated with levamisole. Significant controversy surrounds the role of granulocyte colony stimulating factor (GCSF) in levamisole-associated agranulocytosis. SUMMARY More than three fourths of cocaine users in the United States are exposed to levamisole; a significant minority of these individuals will develop autoimmune-mediated neutropenia, cutaneous vascular complications, and/or leukoencephalopathy. Levamisole exposure should be considered in the differential diagnosis of patients who present with these conditions in the setting of cocaine abuse. Neutropenia appears to resolve rapidly with cessation of exposure, so that GCSF therapy and a work-up for other causes may not be needed in all patients.

Abstract
OBJECTIVE To describe the clinical and serologic abnormalities in 6 patients who presented with retiform purpura and extensive cutaneous necrosis after exposure to levamisole-adulterated cocaine. METHODS All patients were evaluated at San Francisco General Hospital or the University of California San Francisco Medical Center. Each underwent standard screening for substances of abuse and had urine tested for the presence of levamisole by liquid chromatography tandem mass spectrometry. Routine laboratory, autoantibody, and antiphospholipid antibody testing was performed in the hospitals' clinical or reference laboratories. Testing for atypical antineutrophil cytoplasmic antibodies (ANCAs) was performed separately using commercially available enzyme-linked immunosorbent assay kits. RESULTS The patients were women ages 39-50 years who presented with retiform purpura and cutaneous necrosis. Skin biopsies revealed a predominantly small-vessel thrombotic vasculopathy with varying degrees of vasculitis. Four patients were neutropenic. All tested positive for lupus anticoagulant, had IgM antibodies to cardiolipin, and tested strongly positive for ANCAs in a perinuclear pattern by immunofluorescence. Each patient had antibodies to multiple components of neutrophil granules, including neutrophil elastase, lactoferrin, cathepsin G, proteinase 3, and myeloperoxidase. CONCLUSION Rheumatologists should be aware of this distinctive form of necrotic purpura, its associated autoantibodies, and its link to levamisole-adulterated cocaine.

Abstract
We describe a case of antineutrophil cytoplasmic antibody-positive vasculitis from levamisole-tainted cocaine with concomitant cocaine-induced midline destructive lesions of the palate and nasal septum. The diagnosis was confirmed after extensive clinical, laboratory, pathologic, and radiographic testing. Timely recognition of this clinical entity is critical to avoid misdiagnosis and unnecessary treatment with potentially harmful cytotoxic agents. Given the high rate of levamisole contamination within the nation's cocaine supply, clinicians should be alerted to this emerging health threat.

Abstract
Five patients with an antineutrophil cytoplasmic antibody (ANCA)-associated cutaneous vasculopathy secondary to levamisole-adulterated cocaine were prospectively followed up at a single hospital. All patients presented with retiform purpura, with ear involvement being the most characteristic finding. Cocaine metabolites were present on urine toxicology screening, with 2 of 4 of those tested also being positive for levamisole. High-titer polyspecific ANCA and positive antiphospholipid antibody tests were defining laboratory features. Thrombosis and/or leukocytoclastic vasculitis were seen on skin biopsy. Improvement of skin lesions and laboratory findings occurred with cessation of cocaine; however, arthralgias and other complications developed. Levamisole-adulterated cocaine is a cause of a cutaneous vasculopathy associated with characteristic laboratory and clinical features that allow it to be distinguished from classic ANCA-associated small-vessel vasculitides. The chronic sequelae of this syndrome and the potential role for immunosuppression are yet to be completely defined.

Abstract
OBJECTIVES Levamisole is an antihelminthic agent found in nearly 70% of seized U.S. cocaine. Sporadic case literature describes a life-threatening agranulocytosis associated with levamisole exposure secondary to cocaine use. The authors compared the distribution of hematologic indices in a population of cocaine users with and without a confirmed exposure to levamisole. METHODS The records of all patients in the Lifespan hospital system who underwent comprehensive toxicologic testing between September 2009 and December 2009 (n = 799) were reviewed. Of these, 95 patients were eligible for inclusion (cocaine-positive with a simultaneous complete blood count). Patients were grouped into levamisole-positive (n = 47) and -negative (n = 48) groups. The primary outcome measures were total white blood cell count (WBC), absolute neutrophil count (ANC), and absolute lymphocyte count (ALC); secondary outcome measures included percent neutrophils, lymphocytes, eosinophils, monocytes, and basophils, as well as identified co-ingestants. RESULTS Both groups had a similar makeup of age, sex, and race. The total WBC count, ANC, and ALC were not significantly different between the two groups. There was no significant difference in relative proportion of neutrophils, eosinophils, basophils, or monocytes between the groups. There was one neutropenic patient in the levamisole-positive group, while three patients were neutropenic in the negative group. Additionally, a literature review of case reports describing levamisole-induced agranulocytosis (n = 33) was conducted. In 52% of these cases, patients presented with an oropharyngeal chief complaint; in an additional 27%, patients presented with soft tissue infections or purpura. CONCLUSIONS The overall incidence of neutropenia was 4.2% in all cocaine users and 2.1% in the levamisole-positive group. A striking number of the reported patients with levamisole-associated neutropenia have presented to care with oropharyngeal complaints, vasculitis, or fever. A clinical algorithm for identifying levamisole toxicity in the emergency department setting is provided. Further research is necessary to determine the circumstances required for levamisole-associated neutropenia.

Abstract
BACKGROUND AND OBJECTIVES Approximately 70% of illicit cocaine consumed in the United States is contaminated with levamisole. Most commonly used as a veterinary antihelminthic agent, levamisole is a known immunomodulating agent. Prolonged use in humans has been associated with cutaneous vasculitis and agranulocytosis. We describe the development of a systemic autoimmune disease associated with antineutrophil cytoplasmic antibodies (ANCA) in cocaine users. This complication appears to be linked to combined cocaine and levamisole exposure. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Cases were identified between March 2009 and November 2010 at Massachusetts General Hospital's ANCA laboratory. Cocaine exposure was identified from patient history in all cases. Medical records were reviewed for clinical presentation and for laboratory and diagnostic evaluation. RESULTS Thirty cases of ANCA positivity associated with cocaine ingestion were identified. All had antimyeloperoxidase antibodies and 50% also had antiproteinase 3 antibodies. Complete clinical and laboratory data were available for 18 patients. Arthralgia (83%) and skin lesions (61%) were the most frequent complaints at presentation. Seventy-two percent of patients reported constitutional symptoms, including fever, night sweats, weight loss, or malaise. Four patients had biopsy-proven vasculitis. Two cases of acute kidney injury and three cases of pulmonary hemorrhage occurred. From the entire cohort of 30, two cases were identified during the first 3 months of our study period and nine cases presented during the last 3 months. CONCLUSIONS We describe an association between the ingestion of levamisole-contaminated cocaine and ANCA-associated systemic autoimmune disease. Our data suggest that this is a potentially life-threatening complication of cocaine use.

Abstract
Based on the best available data, approximately 2.1 million Americans use illicit cocaine each month; for the last several months, 30% of that cocaine has been "cut" with a veterinary pharmaceutical, levamisole. Levamisole can cause agranulocytosis, leaving patients susceptible to fulminate and opportunistic infections and also can cause a debilitating cutaneous necrotizing vasculitis. In this manuscript, we describe a case and provide an image of levamisole-induced necrotizing vasculitis of the ears.

Abstract
BACKGROUND Dermatologists at the University of California, San Francisco recently reported two patients in the online Journal of the American Academy of Dermatology with purpura presumably induced by levamisole in contaminated cocaine. Levamisole-induced vasculitis and neutropenia has been reported elsewhere in the United States and Canada. Up to 70% of cocaine in the United States could be contaminated. OBJECTIVE We sought to describe similar cases of vasculitis associated with cocaine use. METHODS This is a retrospective case series. RESULTS We report 6 remarkably similar patients seen over just the past few months with retiform purpura on the body and tender purpuric eruptions, necrosis, and eschars of the ears after cocaine use in New York and California. All of these patients had positive perinuclear antineutrophil cytoplasmic antibody values and 3 of the 6 also had an associated neutropenia. Direct immunofluorescence studies suggested an immune complex-mediated vasculitis. LIMITATIONS This case series is descriptive in nature and, because testing is not easily performed, we did not test for levamisole in the serum or blood to prove this is the causative agent. CONCLUSION It appears the use of cocaine is associated with the peculiar clinical findings of ear purpura, retiform purpura of the trunk, and neutropenia. We believe this case series may represent the tip of the iceberg as a looming public health problem caused by levamisole. Although the direct causal relationship may be difficult to establish, the astute dermatologist or primary care physician should be able to recognize the characteristic skin lesions and should be wary of the potential development of agranulocytosis.

Abstract
OBJECTIVES Reports of an association between antineutrophil cytoplasmic antibodies (ANCA) and autoimmune neutropenia have rarely included cases of proven vasculitis. A case of ANCA-associated vasculitis (AAV) with recurrent neutropenia is described and relevant literature on the association between ANCA, neutropenia, and vasculitis is reviewed. METHODS Longitudinal clinical assessments and laboratory findings are described in a patient with AAV and recurrent episodes of profound neutropenia from December 2008 to October 2010. A PubMed database search of the medical literature was performed for articles published from 1960 through October 2010 to identify all reported cases of ANCA and neutropenia. RESULTS A 49-year-old man developed recurrent neutropenia, periodic fevers, arthritis, biopsy-proven cutaneous vasculitis, sensorineural hearing loss, epididymitis, and positive tests for ANCA with specificity for antibodies to both proteinase 3 and myeloperoxidase. Antineutrophil membrane antibodies were detected during an acute neutropenic phase and were not detectable in a postrecovery sample, whereas ANCA titers did not seem to correlate with neutropenia. An association between ANCA and neutropenia has been reported in 74 cases from 24 studies in the context of drug/toxin exposure, underlying autoimmune disease, or chronic neutropenia without underlying autoimmune disease. In these cases, the presence of atypical ANCA patterns and other antibodies were common; however, vasculitis was uncommon and when it occurred was usually limited to the skin and in cases of underlying toxin exposure. CONCLUSIONS ANCA is associated with autoimmune neutropenia, but systemic vasculitis rarely occurs in association with ANCA and neutropenia. The interaction between neutrophils and ANCA may provide insight into understanding both autoimmune neutropenia and AAV.

Abstract
The term 'cocaine-induced pseudovasculitis' was coined to encompass a constellation of clinical and laboratory findings which mimics a systemic vasculitis but lacks confirmatory evidence of vasculitis on biopsy. Antineutrophil cytoplasmic antibodies reacting with human neutrophil elastase (HNE) have been reported to distinguish the cocaine-related syndrome from a true autoimmune vasculitis. Published cases of retiform purpura related to cocaine use are rare and an etiologic role for levamisole, a common adulterant of cocaine, has been postulated. We describe two female patients aged 39 and 49 years with cocaine-related retiform purpura, mainly affecting the legs. The initial clinical and serological profile in case 1 led to a suspicion of anti-phospholipid syndrome and in case 2 to Wegener's granulomatosis with an unexplained associated neutropenia. Skin biopsies revealed a mixed pattern of leukocytoclastic vasculitis and microvascular thrombosis in case 1 and pure microvascular thrombosis in case 2. Identification of anti-HNE antibodies in both patients linked their disease to cocaine. The mixed vasculopathic pattern in case 1 and the associated neutropenia in case 2, both known adverse effects of levamisole, point to this as the true etiologic agent. Urine toxicology shortly after a binge of cocaine use in each case was positive for levamisole.

Abstract
More than 2 million Americans use cocaine each month (National Survey on Drug Use and Health, Department of Health and Human Services: Substance Abuse and Mental Health Services Administration (SAMHSA) & Office of Applied Studies (OAS), Rockville, MD 2007). Starting in early 2003, South American cocaine cartels began to add levamisole, a pharmaceutical agent, to bulk cocaine prior to shipment to the USA (Valentino and Fuentecilla 2005). A dramatic increase in the prevalence of levamisole in cocaine was noted in early 2008. By October, 30% of cocaine bricks analyzed by the United States Drug Enforcement Administration contained levamisole (Casale et al. 2008). Exposure to levamisole can cause agranulocytosis (Amery and Bruynseels 1992). We report the first confirmed case of agranulocytosis associated with consumption of levamisole-contaminated cocaine in the USA. A previously healthy adult male presented to the emergency department with 5 days of mouth pain. He admitted to chronic active ethanol and crack cocaine abuse. Laboratory studies revealed severe neutropenia, with an absolute neutrophil count of 19 cells/mm³ (normal = 1,500-8,000 cells/mm³). A urine screen for drugs of abuse was positive for cocaine metabolites and opiates. Evaluation of a peripheral blood smear showed leukopenia with severe absolute neutropenia. A bone marrow biopsy revealed recently injured bone marrow showing early recovery. While in the hospital, the patient had little spontaneous bone marrow recovery. He received granulocyte colony-stimulating factor with improvement in peripheral white blood cell counts. The residue in the patient's crack pipe contained 10% levamisole. Subsequently, levamisole was detected in the patient's urine. Levamisole-associated agranulocytosis should be considered in the diagnosis of patients who present with neutropenia and a history or evidence of cocaine use.

Levamisole tainted cocaine causing severe neutropenia in Alberta and British Columbia. Harm Reduct J 2009; 6:30.

Abstract
BACKGROUND Five cases of severe neutropenia (neutrophil counts < 0.5 per 109 cells/L) associated with exposure to cocaine and levamisole, an antihelimithic agent no longer available in Canada, were identified in Alberta in 2008. Alberta and British Columbia (BC) public health officials issued an advisory and urged health care professionals to report cases to public health. This paper presents the findings of the public health investigations. METHODS Cases were identified prospectively through reporting by clinicians and a retrospective review of laboratory and medical examiners data from January 1, 2006 to March 31, 2009. Cases were categorized as confirmed, probable or suspect. Only the confirmed and probable cases are included in this paper. RESULTS We compare cases of severe neutropenia associated with tainted cocaine (NATC) identified in Alberta and BC between January 1, 2008 to March 31, 2009. Of the 42 NATC cases: 23(55%) were from Alberta; 19(45%) were from British Columbia; 57% of these cases reported crack cocaine use (93% of those who identified type of cocaine used); 7% reported using cocaine powder; and the main route of cocaine administration was from smoking (72%). Fifty percent of the NATC cases had multiple episodes of neutropenia associated with cocaine use. Cases typically presented with bacterial/fungal infections and fever. One Alberta NATC case produced anti-neutrophil antibodies, and four were positive for anti-neutrophil cytoplasmic antibody (ANCA). Analysis of two crack pipes and one drug sample obtained from NATC cases confirmed the presence of both cocaine and levamisole. A further 18 cases were identified through the retrospective review of laboratory and medical examiner data in Alberta INTERPRETATION Our findings support a link between neutropenia and levamisole tainted cocaine; particularly from smoking the crack form of cocaine. Some patients may be genetically predisposed to develop levamisole-related neutropenia. Awareness of the differential diagnosis will assist clinicians with case timely detection and appropriate management.

Abstract
Many children with steroid-dependent nephrotic syndrome (NS) have significant sequelae despite steroid-sparing therapies. Levamisole may reduce short-term relapse frequency (RF) with minimal side effects. Little data exist, however, as to its long-term effect. To assess both short- and long-term efficacy in NS, RF and cumulative annual steroid burden were quantified in ten consecutive children with steroid-dependent NS treated with levamisole. Data were analyzed for three time periods: 1 year prior to levamisole therapy (Pre-Lev), during 1 year of levamisole therapy (During-Lev), and the year after cessation of all levamisole therapy (Off-Lev). Median RF fell from 6.0 (4.0-9.0) relapses/patient per year Pre-Lev to 0.0 (0.0-4.0) During-Lev (p = 0.002) with 6/10 patients having no relapse and 0.5 (0.0-8.0) Off-Lev (p = 0.01) with 5/10 patients without relapse. Concurrently, cumulative annual steroid burden fell from 6,067 (1,660-8,691) mg/m(2) per year Pre-Lev to 2,920 (782-5,271) During-Lev (p = 0.002) and 716 (0-3,637) Off-Lev (p = 0.002). In 4/5 hypertensive children, blood pressure normalized During-Lev. Somatic indices also improved: height Z scores, which fell from 0.8 (-2.4 to 3.6) at diagnosis to -0.6 (-2.7 to 0.4) Pre-Lev (p = 0.004), remained stable at -0.6 (-3.0 to 0.6) after 1 year of therapy and -0.5 (-2.6 to 0.2) Off-Lev. Height velocity improved from 3.0 (0.3-6.0) cm/year Pre-Lev to 3.7 (0.0-8.0) cm/year During-Lev and 5.4 (0.0-9.1) Off-Lev. We conclude that levamisole is an effective short- and long-term steroid-sparing agent in pediatric NS.

Abstract
The effects of levamisole treatment on long-term outcome were evaluated in a retrospective study of frequently-relapsing (FRNS, n=15), steroid-dependent (SDNS, n=13), and steroid-resistant (SRNS, n=6) nephrotic syndrome in 34 children (21 boys, 13 girls, mean age 5.0+/-3.4 years) during a 60-month follow-up period. The definition of frequent relapses was > or = 4 relapses per year. The current relapse was treated with prednisolone 60 mg/m2 per day for 4 weeks, then with 40 mg/m2 every other day for 4 weeks, after which the dose was tapered by 10 mg weekly. From the beginning of the 5th week, levamisole was introduced at a dose of 2 mg/kg per day. The duration of levamisole treatment was 17+/-7 months. Before starting levamisole treatment the mean level of proteinuria was 2.17+/-1.34 g/day and the relapse rate was 4.41/year. By the end of levamisole therapy, proteinuria had fallen to 0.142+/-0.211 g/day and the relapse rate to 0.41/year. No relapse occurred in 23 of the 34 patients during levamisole treatment. In the 24-month follow-up period after the discontinuation of levamisole, 28 children remained in total remission, while 6 had relapses. The cumulative steroid dose before levamisole therapy was 7,564.4+/-3,497.1 mg/year and following the introduction of levamisole 1,472.9+/-1,729.9 mg/year (P<0.0001). We observed reversible neutropenia in 5 patients, but no other side effects were seen. Our findings suggest that in FRNS and SDNS levamisole significantly reduces both the relapse rate and the cumulative steroid dose; therefore, it could be recommended for these patients. In SRNS patients it has also some benefit because proteinuria and the cumulative steroid dose could be reduced significantly.
