Levamisole toxicity resulting from the use of adulterated cocaine may be an increasing problem and should be considered in a cocaine user with neutropenia and reticular purpura. A patient in New York was diagnosed with and compromised kidney function caused by levamisole-adulterated cocaine, which scientists consider to be a rare occurrence. The study, “,” was published in. Levamisole is an anthelmintic (meaning “destructive to parasitic worms”) drug with immunomodulatory properties. License Ricoh. Bit depth is defined automatically and displayed in the sidebar.

As such, it has been used in the treatment of tumors and other diseases characterized by immune dysfunction, including. In 2000, however, levamisole was pulled from the U. Market because of adverse effects related to its toxicity. Although used legitimately for some uses in veterinary medicine, it is now being used illicitly as a, and experts believe it is in most of the cocaine distributed in the United States. The exact purpose for adding levamisole to cocaine is unknown, but scientists think it furthers cocaine’s stimulant effect. Complications associated with use of levamisole-adulterated cocaine include low levels of neutrophils (a type of white blood cell), severe reduction in the total amount of white blood cells, joint pain, branching purpuric skin lesions, inflammation of blood vessels walls (vasculitis), and skin necrosis (premature death of skin cells). However, renal side effects of these two drugs combined are uncommon. Researchers at in the Bronx, New York, described the case of a 40-year-old Hispanic man who was admitted to the rheumatology clinic with acute kidney problems. The patient had a history of cocaine addiction and was being treated at that same facility for chronic inflammatory arthritis. Biochemical testing revealed high serum creatinine levels, red blood cells and protein in the urine. Creatinine is a waste product from normal muscle metabolism. Healthy kidneys remove creatinine from the blood; so, a high concentration of creatinine is indicative of kidney damage. Kidney tissue analysis showed focal proliferation of cells inside Bowman’s capsule — the initial part of a nephron (the basic structural and functional unit of the kidney that removes waste from the body and produces urine) along with cellular death and mild immune complex deposition, which is a cluster of interlocking proteins and antibodies. To describe these disease features, doctors use the term “necrotizing crescentic glomerulonephritis,” which is typical of small-vessel vasculitis in the kidney. The patient also tested positive for proteinase 3, myeloperoxidase, anticardiolipin antibodies and antinuclear antibody, leading to a diagnosis of vasculitis. Investigators chose a treatment regimen tailored for, which apart from the patient having to stop using cocaine, included pulse dose steroids followed by maintenance prednisone to reduce inflammation, Rituxan (rituximab) to reduce the number of B-cells (immune cells involved in producing ANCA, the trigger for the immune system to start attacking the blood vessels), and cyclophosphamide to suppress the auto-reactive immune system. Consequently, the man’s kidney function improved, but did not return to normal. “We believe that his incomplete improvement was due to the degree of kidney injury on presentation [at the hospital] as well as recidivism with cocaine use,” investigators concluded.

Levamisole is an immunomodulatory agent that was used to treat various cancers before being withdrawn from the United States market in 2000 because of adverse effects. Levamisole is currently approved as an antihelminthic agent in veterinary medicine, but is also being used illicitly as a cocaine adulterant. Potential complications associated with use of levamisole-laced cocaine include neutropenia, agranulocytosis, arthralgias, retiform purpura, and skin necrosis. ![]() Treatment is primarily supportive, and skin lesions typically resolve with cessation of cocaine use. The incidence of hospitalizations related to use of levamisole-contaminated cocaine continues to increase and clinicians should be aware of the more common clinical manifestations. Cocaine use and its related complications are well-known public health issues. More than 5 million Americans use cocaine regularly via insufflation (snorting/sniffing), inhalation (smoking), and injection. Cocaine's effects on the health care system cross multiple medical disciplines, but clinicians may be less cognizant of the problems caused by some of the adulterants added to cocaine. Recent recognition of levamisole-induced agranulocytosis, vasculitis, and other complications, from contaminated cocaine, dictate that physicians be aware of these potential problems.
