Abstract
HISTORY AND CLINICAL FINDINGS A 20-years-old patient presented himself to our emergency room with extensive and extremely painful purpura with necrotizing spots and blisters, especially on the lower extremities, but also on the arms, trunk and ears. There was a pre-existing use of cocaine. MEDICAL EXAMINATIONS Laboratory tests showed increased signs of inflammation as well as an increase in proteinase 3- and myeloperoxidase-ANCA (Anti-neutrophil cytoplasmatic antibody). DIAGNOSIS In combination with the medical history, the clinical findings, and the laboratory values, vasculitis of the skin after cocaine use was revealed. THERAPY AND COURSE Under therapy with steroids and cocaine abstinence, there was a regression of the changes. CONCLUSION Vasculitis is a serious complication of cocaine use.

Abstract
Early identification of cutaneous manifestations of alcohol and illicit drug use can aid in the diagnosis and management of these uses, as well as their sequelae. In addition, the effects of alcohol and illicit drug use on the skin can result in significant morbidity. Alcohol misuse can present with jaundice, pruritus, pigmentary alterations, urticaria, hair and nail changes, and oral changes. It is also a risk factor for skin cancer and infections. Vascular disturbances associated with alcohol misuse include telangiectasias, palmar erythema, caput medusae, and flushing. Diseases related to alcohol misuse include nutritional deficiencies, porphyria cutanea tarda, psoriasis, seborrheic dermatitis, nummular dermatitis, and rosacea. Other conditions seen in alcohol misuse include Dupuytren contracture, Peyronie disease, and pancreatitis. Dermatologists should also be aware of hepatotoxic medications that are commonly prescribed for skin diseases so as to avoid initiating hepatoxicity in patients who use alcohol. Illicit drug use can manifest with cutaneous fibrosis, scarring, granulomas, ulceration, pruritus, infections, cocaine-levamisole-induced vasculitis, tooth decay, and oral disease. By recognizing the cutaneous stigmata of alcohol and illicit drug use, dermatologists can aid in the identification and treatment of patients suffering from these addictions.

Abstract
CASE PRESENTATION A 50-year-old woman presented to the ED with a 3-day history of increasing confusion. Prior to her presentation, the patient had been in her usual state of health as reported by her family. She had a history of bipolar disorder and attention-deficit/hyperactivity disorder but had stopped her psychiatric medications for the past 4 days secondary to loss of insurance coverage. History was limited due to the patient's altered state and confusion, and was obtained from family. There was no history of headache, loss of consciousness, weakness of extremities, seizures, fever, or recent trauma. The patient's medical history also included cocaine abuse. The patient's family believed she had been abstinent from cocaine use for several years.

Abstract
Novel drugs of abuse are synthetic illicit drugs, or analogues of known illicit drugs, that can be more potent. Novel drugs of abuse are often labeled as designer drugs, research chemicals, legal highs, or psychoactive substances. They are often sold as designated legal or nondrug products, such as incense, plant food, or bath salts, with labeling such as "Not for Human Consumption" or "For Use in Research Only." The prevalence of use of novel drugs of abuse is difficult to determine because specific drugs, compounds, and availability of these drugs are constantly evolving. Changes in chemical structures lead to heterogeneity in physiologic response and clinical symptoms, even within the same category of drug. Pediatricians and emergency medicine physicians should be knowledgeable about novel drugs of abuse and their resulting symptoms for prevention and identification of their use.

Abstract
Levamisole is an increasingly common cocaine adulterant that can cause severe and rapid onset cutaneous vasculitis in humans. While most cases may be managed conservatively, we describe a series of patients in whom the extent of skin and soft tissue necrosis mandated surgical intervention. A retrospective review of all patients admitted to one of two regional burn centers between 2006 and 2016 for soft tissue necrosis after exposure to levamisole-adulterated cocaine was included in our study. Ten patients, majority female (9/10) with an average age of 43.4 years (range 31-57), were included. Cocaine usage before presentation averaged 6 days (range 1-14). Presenting complaints consisted of arthralgia (5/10), fever (7/10), and purpuric lesions (10/10). Average TBSA involvement was 23.5% (range 4-70). Immunological testing revealed perinuclear antineutrophil cytoplasmic antibody (pANCA+) in 8 of 10 and cytoplasmic antineutrophil cytoplasmic antibody (cANCA+) in 4 of 8 patients. Operative intervention occurred by postadmission day 11.6 (range 3-30). The mean number of operations required was 3 (range 2-6); length of stay averaged 46.8 days (range 14-120); and survival to discharge was 100% (10/10). To our knowledge, this is the largest case study detailing the surgical management of levamisole-associated skin necrosis. Additionally, we describe the most extensive case of this disease process at 70% TBSA involvement. Based on our experience, we recommend waiting for purpuric rash resolution and soft tissue necrosis to be fully demarcated before fascial debridement and then staged skin grafting with allograft followed by autograft.

Abstract
BACKGROUND AND AIMS On-line drug markets flourish and consumers have high expectations of on-line quality and drug value. The aim of this study was to (i) describe on-line drug purchases and (ii) compare on-line with off-line purchased drugs regarding purity, adulteration and price. DESIGN Comparison of laboratory analyses of 32 663 drug consumer samples (stimulants and hallucinogens) purchased between January 2013 and January 2016, 928 of which were bought on-line. SETTING The Netherlands. MEASUREMENTS Primary outcome measures were (i) the percentage of samples purchased on-line and (ii) the chemical purity of powders (or dosage per tablet); adulteration; and the price per gram, blotter or tablet of drugs bought on-line compared with drugs bought off-line. FINDINGS The proportion of drug samples purchased on-line increased from 1.4% in 2013 to 4.1% in 2015. The frequency varied widely, from a maximum of 6% for controlled, traditional substances [ecstasy tablets, 3,4-methylenedioxy-methamphetamine (MDMA) powder, amphetamine powder, cocaine powder, 4-bromo-2,5-dimethoxyphenethylamine (2C-B) and lysergic acid diethylamide (LSD)] to more than a third for new psychoactive substances (NPS) [4-fluoroamphetamine (4-FA), 5/6-(2-aminopropyl)benzofuran (5/6-APB) and methoxetamine (MXE)]. There were no large differences in drug purity, yet small but statistically significant differences were found for 4-FA (on-line 59% versus off-line 52% purity for 4-FA on average, P = 0.001), MDMA powders (45 versus 61% purity for MDMA, P = 0.02), 2C-B tablets (21 versus 10 mg 2C-B/tablet dosage, P = 0.49) and ecstasy tablets (131 versus 121 mg MDMA/tablet dosage, P = 0.05). The proportion of adulterated samples purchased on-line and off-line did not differ, except for 4-FA powder, being less adulterated on-line (χ2 = 8.3; P < 0.02). Drug prices were mainly higher on-line, ranging for various drugs from 10 to 23% higher than that of drugs purchased off-line (six of 10 substances: P < 0.05). CONCLUSIONS Dutch drug users increasingly purchase drugs on-line: new psychoactive substances in particular. Purity and adulteration do not vary considerably between drugs purchased on-line and off-line for most substances, while on-line prices are mostly higher than off-line prices.

Abstract
Complications due to cocaine are a public health problem. The typical cutaneous disease is leukocytoclastic vasculitis and/or thrombotic vasculopathy affecting mainly the ears. No intense systemic involvement is usually present, but there may be several cutaneous, mucosal and systemic manifestations. Other findings associated as arthralgia, neutropaenia or agranulocytosis, low titer positive antinuclear antibodies, antiphospholipid antibody positivity and neutrophil cytoplasmic antibodies against multiple antigens help the diagnosis. This disease requires a clinical suspicion with a clinical history, a complete physical examination and a broad differential diagnosis for an early and correct diagnosis. The course is usually self-limited. In most cases the only treatment is to discontinue the use of cocaine associated with symptomatic treatment, no proven benefit of systemic corticosteroids.

Abstract
Levamisole is an antihelminthic and immunomodulator medication that was banned by the USFDA in 1998. It has been increasingly used to adulterate cocaine due to its psychotropic effects and morphological properties. Adverse reactions including cutaneous vasculitis, thrombocytopenia, and agranulocytosis have been well described. Despite systemic vasculitis in this setting, renal involvement is uncommon. We report here a case of ANCA positive systemic vasculitis with biopsy proven immune complex mediated glomerulonephritis likely secondary to levamisole/cocaine. A 40-year-old Caucasian male with no past medical history presented with 3-week history of fatigue, skin rash, joint pains, painful oral lesions, oliguria, hematuria, worsening dyspnea on exertion, and progressive lower extremity edema. He had a history of regular tobacco and cocaine use. Lab testing revealed severe anemia, marked azotemia, deranged electrolytes, and 4.7 gm proteinuria. Rheumatologic testing revealed hypocomplementemia, borderline ANA, myeloperoxidase antibody, and positive atypical p-ANCA. Infectious and other autoimmune workup was negative. Kidney biopsy was consistent with immune mediated glomerulonephritis and showed mesangial proliferation and immune complex deposition consisting of IgG, IgM, and complement. High dose corticosteroids and discontinuing cocaine use resulted in marked improvement in rash, mucocutaneous lesions, and arthritis. There was no renal recovery and he remained hemodialysis dependent.

Abstract
Levamisole is an immunomodulatory and antihelminthic drug, previously removed from the United States market, and now estimated to be present in the vast majority of cocaine distributed in the United States. Levamisole-adulterated cocaine (LAC) exposure can result in neutropenia, thrombocytopenia, and vasculitis with a predilection for subsites of the face. The objective of this review is to increase awareness among otolaryngologists of the manifestations of LAC exposure. We present the case of a 33-year-old woman with a history of cocaine use, consulted for purpuric, necrotic lesions of the nose, cheeks, and ears, with accompanying leukopenia, thrombocytopenia, and positive antineutrophil cytoplasmic antibodies (ANCA). The effects of levamisole are immune mediated, with antibodies directed against neutrophils causing neutropenia, and vasculitis caused by antibody deposition or secondary to induction of antiphospholipid antibodies causing thrombosis. LAC exposure can be differentiated from other similar appearing pathologies by evaluating serology for specific ANCA. The most important treatment is cessation of cocaine use, which most often results in complete resolution of symptoms. Awareness of the presentation, complications, and treatment of LAC exposure may be especially important for otolaryngologists, who may be one of the firsts to evaluate an affected patient.

Abstract
Cocaine-induced vasculitis is a rare complication found in drug abusers. It occurs due to cocaine adulterated with levamisole. Levamisole was once used as a chemotherapy and immunomodulator for different conditions. One of the side effects of this medication is necrotizing vasculitis which has been reported in the US and Puerto Rico. Here we present another case of cocaine induced vasculitis in Puerto Rico. We describe a 43-year-old female with past medical history of bronchial asthma, migraine, and crack smoking who presented to the emergency room due to blood in her urine for 5 days. She also reported fever, chills, and fatigue. At the physical exam she had a right knee ulcer with swelling erythema, warmth, and pain. Also, she had retiform purpuric plaque lesions in her ears, bilaterally. Eroded plaques with elevated borders at left foot and finger dorsum were also present. Laboratory workup was positive for cocaine. The patient showed leucopenia and microcytic anemia with a normal absolute neutrophil count in her cell blood count. Blood cultures, urine cultures, and ulcer cultures were negative. Urinalysis was positive for proteinuria and hematuria. Also, the patient had positive perinuclear anti-neutrophil cytoplasmic antibody, cytoplasmic anti-neutrophil cytoplasmic antibody, and antinuclear antibody tests and elastase specificity. She showed negative anticardiolipin and lupus anticoagulant antibodies. Her complement levels were decreased. The punch biopsy of her ear showed superficial thrombosis of superficial vascular plexus with perivascular lymphocytic infiltrates and deeper sections showed epidermal necrosis and necrotizing vasculitis. She was started on a high dose of steroids, but could not complete the treatment because she escaped from the hospital before finishing her treatment.

Abstract
Background: Levamisole was removed from the market due to complications of agranulocytosis and skin necrosis. Levamisole has been reported in a high proportion of seized cocaine in North America and has been associated with multiple cases of skin necrosis. Objective: We report three cases of levamisole/cocaine-induced skin necrosis who responded to treatment with plasmapheresis and immunosuppression. Results: Three patients presented with painful necrotic skin lesions on the ears, cheeks, breasts, and buttocks. The extremities were involved in two patients and the upper respiratory tract mucosa in one patient. All had markers of immune activation, with elevated C-reactive protein, antinuclear antibody, and perinuclear antineutrophil cytoplasmic antibody. Skin biopsy in all cases revealed a mixed pattern of thrombosis and vasculitis within dermal vessels, with overlying ischemic ulceration of skin and soft tissues. One patient required extensive debridement of the skin and soft tissue of the calves and also had respiratory involvement. All patients were treated with plasmapheresis and immunosuppression with rapid stabilization and/or improvement of the lesions. Conclusion: Levamisole is frequently added to crack/cocaine; we report three patients who developed vascular lesions and skin necrosis after using cocaine/levamisole. These improved with plasmapheresis and immunosuppression as well as abstention from the drugs; one patient with severe disease required debridement and skin grafting.

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
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
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
Levamisole-induced vasculitis is a relatively new entity in people who use cocaine. We describe a 44-year-old woman with a history of cocaine use who presented with a complaint of a painful rash of 2-3 month’s duration on her extremities, cheeks, nose, and earlobes. She had not experienced fever, weight loss, alopecia, dry eyes, oral ulcers, photosensitivity, or arthralgia. Examination revealed tender purpuric eruptions with central necrosis on her nose, cheeks, earlobes, and extremities. Laboratory investigations revealed neutropenia, an elevated erythrocyte sedimentation rate (ESR), presence of lupus anticoagulant, low complement component 3 (C3), and presence of perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA). A urine toxicology screen was positive for cocaine, and gas chromatography–mass spectrometry was positive for levamisole. Skin biopsy showed leukocytoclastic vasculitis and small vessel thrombosis. Necrotic lesions of the nose led to its self-amputation. Large bullae on the lower extremities ruptured, leading to wound infection and extensive necrosis that required multiple surgical debridements. When necrosis progressed despite debridement, bilateral above-knee amputation of the legs was performed. Once new lesions stopped appearing, the patient was discharged home. Two months later, she had a recurrence related to cocaine use. To the best of our knowledge, this is only the second reported case of levamisole-induced vasculitis that required above-knee amputation.

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
PURPOSE OF REVIEW New drugs are continuously being developed and some rheumatic syndromes have been associated with specific drugs. As most of the rheumatic diseases are multisystem, it is worthwhile examining the wider case report literature to see whether any recent studies signify new associations between drugs and the rheumatic diseases. The last 2 years' case reports in English were scrutinized for noninfectious association with the rheumatic diseases. Cross-referencing from MEDLINE was performed using several databases including Google scholar; British Medical Journal (BMJ) case reports were also queried separately. RECENT FINDINGS Fifty-three articles comprising 56 case reports are included in the review, with 27 (48.2%) associated with the vasculitides, eight (14.3%) associated with lupus and 13 (23.2%) were associated with the myositis syndromes. The commonest four groups of drugs to potentially induce rheumatic diseases were anti-tumour necrosis factor (TNF) drugs, oncology drugs, propylthiouracil and interferons. SUMMARY It is important to recognise that drugs used in other specialties may induce rheumatic disease and vigilance on making a diagnosis is the key.

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
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
Cocaine abuse is relatively common in our society. To enhance profitability and acceptability of the product, it is not uncommon for illicit drugs to undergo several processes. The Drug Enforcement Agency (DEA) has reported that seventy percent (70%) of cocaine seized at USA borders has been adulterated with levamisole, previously used as chemotherapeutic and immunomodulator for several conditions. Among the side effects of levamisole-adulterated cocaine, necrotizing vasculitis is the more dramatic. We report three cases of necrotizing vasculitis associated with antineutrophils cytoplasmic antibodies (ANCAs) positivity, linked to the use of cocaine. To our knowledge, these are the first cases of cocaine induced vasculitis reported in the Caribbean.

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
Levamisole is found in more than 80% of illicit cocaine seized within United States borders. Percentages are somewhat lower in Europe. In 2009, controlled in vivo studies demonstrated that horses metabolize levamisole to aminorex. Earlier this year our laboratory demonstrated that the same conversion occurs in man. Levamisole itself causes aplastic anemia and numerous reports have begun to appear in the literature, but the conversion of levamisole to aminorex is of much more concern. Aminorex ingestion was responsible for a five-year epidemic (1967-1972) of idiopathic pulmonary hypertension (IPH) confined to Switzerland, Austria, and Germany, the only countries where aminorex had been marketed as an anorectic. The incidence of IPH reverted to normal levels as soon as aminorex was withdrawn. In most cases onset of symptoms in IPH began after six to nine months of aminorex use, with average dosage ranges of 10 to 40 mg per day. The outcome was almost uniformly fatal. The conversion rate of levamisole to aminorex has not been established, but given the high daily intake of cocaine by many abusers, it seems likely that many of them will have ingested enough contaminated cocaine to ultimately cause IPH. Until the disease is well established, the symptoms of IHP are vague, and existing drug registries specifically exclude drug abusers, making it difficult to track these cases. This review is intended to draw attention to what may be a slowly emerging new epidemic.
