what is drug induced lupus

Some people are born with a tendency toward developing lupus, which may be triggered by infections, certain drugs or even sunlight. Hundreds of drugs have been linked to lupus-like symptoms, alcoholic eyes but a few are particularly notable. Not everyone who takes these drugs will get lupus, but it’s helpful to be aware of the risk if you take one or more of these medications.

Tumor Necrosis Factor Inhibitors

Other autoantibodies against antigens including smith, ribonuclear protein (RNP), SCL70, centromere, Jo-1 are rare in DIL and may help differentiate DIL from other autoimmune disorders. Both interferon-alpha and interferon-beta have been linked to the development of DIL. As the case with anti-TNF agents, autoantibody development including ANA and Anti-dsDNA is common, while DIL develops in less than 2% cases.[10] Arthralgia, arthritis, and leukopenia are the usual manifestations. Minocycline induced lupus is more common in younger females, while procainamide or hydralazine induced lupus is more common in the elderly population. Hundreds of drugs have been reported to cause DIL.[2][3] While some drugs have good evidence of association with DIL, there are case reports implicating several other drugs as a possible cause of DIL. Several herbal medications have also been reported to cause a lupus-like syndrome.

Some people who have lupus due to quinidine or hydralazine may test ANA-negative. The study published in Nature found that there’s a T cell imbalance in lupus patients. T cells, in case you’re not familiar with them, are white blood cells that are part of the immune system, per the National Cancer Institute (NCI). alcohol and seizures can drinking cause epilepsy or convulsions T cells develop from stem cells in the bone marrow and help protect the body from infection, the NCI says. Diagnosing lupus can be challenging because symptoms can vary from person to person, and they can come and go. Sometimes it can take years to gather all the right information for an accurate diagnosis.

International Patients

Procainamide is an antiarrhythmic — a drug that treats irregular heart rhythms. The incidence of lupus as a side effect has been reported to be as high as 30 percent, according to StatPearls, a clinic support tool. The list of drugs implicated in triggering DILE is expanding as new drugs with novel mechanisms of action are being developed.

  1. Care must be taken to correctly diagnose the symptoms of DILE and differentiate it from systemic lupus erythematosus (SLE), and DILE should be recognized clinically and serologically for prompt intervention.
  2. For example, the first onset of typical subacute cutaneous LE in an older person, especially if involving the legs, should raise the suspicion of drug-induced LE.
  3. Since staying on it is dangerous, you and your healthcare provider will need to discuss alternative treatments for whatever condition the drug was intended to treat.
  4. The antibiotic minocycline (Minocin) is used to treat many infections, including respiratory tract issues such as pneumonia.
  5. This interaction causes the formation of reactive metabolites that directly affect lymphocyte function in the thymus, disrupting central T-cell tolerance to the patient’s own tissues and producing autoimmune T cells against them.

If patients with DILE are given anti-inflammatory medication, this may mask the symptoms and thus potentially result in misdiagnosis. Low doses of systemic corticosteroids may be prescribed for short periods if the symptoms of DILE are severe (eg, polyarthritis resulting in debilitating inflammation in many joints simultaneously). Fever is found in similar incidence in both TNF-α inhibitor–induced DILE and DILE caused by other categories of medications.

Angular Cheilitis vs. Lupus Rash: 4 Differences To Note

People with DIL caused by quinidine or hydralazine may have negative ANA results. It’s more likely to develop in White people than African-Americans, as well. More than 40 drugs have been known to cause this form of lupus, but several are considered primary culprits. Below are some of the most common questions and answers about drug-induced lupus. Keep your arms and legs covered, and use sunscreen with an SPF of at least 55.

Since drug-induced lupus is likely to improve once you stop taking the drug, long-term treatment is usually not necessary. Read on for a list of drugs that can cause lupus, how it’s diagnosed, and what you can expect if you have it. SLE is a chronic condition that can cause inflammation anywhere in the body, including internal organs such as the kidneys or lungs.

There are about 15,000 to 20,000 new cases of drug-induced lupus diagnosed each year in the United States, usually in people between 50 and 70 years old. They found that Type I interferon modulates a receptor called aryl hydrocarbon receptor (AHR) which leads to increased production alcohol withdrawal syndrome of a subset of T cells that activate B cells, resulting in an increase in inflammation. CDC supports national organizations, public health agencies, universities, and communities to undertake lupus awareness activities, epidemiologic research, and public health programs.

They may also order blood tests and urinalysis to check for certain antibodies, which can suggest an autoimmune process. If the diagnosis is drug-induced lupus, you’ll need to consult with the doctor who prescribed the drug so you can find an alternative treatment. Your doctor will work with you to find a substitute for the medication that caused the problem. Taking these medications does not mean you’ll develop drug-induced lupus. New research published in the journal Nature may have found the root cause behind lupus, pointing to abnormalities in the immune systems of people with the disease.

People with lupus nephritis have a higher risk of needing dialysis or a kidney transplant for treatment of their disease. The study found that giving people with lupus anifrolumab, a drug that blocks interferon, prevented the T-cell imbalance that likely leads to the disease. Many of the current options broadly suppress the immune system, including beneficial T cells that fight infection. And for some people with the disease, standard treatments aren’t effective. Now, a study published Wednesday in the journal Nature outlines a clear pathway for how the disease likely develops, pointing to abnormalities in the immune systems of people with lupus. A key mystery behind one of the most common autoimmune diseases may finally have an answer.

Constitutional symptoms, such as malaise, low-grade fever, and weight loss, are a frequent presenting symptom complex. Serositis (pleural effusion and pericarditis) and pneumonitis are classically found in procainamide-related DIL. Dermatologic manifestations, renal involvement, and neurologic symptoms are rare in classic DIL [23].

In some cases, a doctor may refer a person to a rheumatologist or another specialist. A person should speak with a doctor if they think they may be experiencing drug-induced lupus. But usually, it takes from several months to 2 years of regular use before you have symptoms. Several famous women have spoken out about having lupus, including Selena Gomez and Halsey.

Clinical and immunological features may vary for each agent responsible for the development of DIL. Work with your healthcare provider to find the correct diagnosis, an alternative drug, and the treatments that can help you manage the symptoms of DIL until they go away. Once you’re off the offending medication, the prognosis is generally excellent. To diagnose the condition, a doctor may order different tests and perform a physical exam. To determine which drug triggers drug-induced lupus, a person may have to stop certain medications under a doctor’s supervision and note changes. The symptoms will typically recede within weeks after a person stops taking the triggering medication.

Typically, after a person stops taking the medication, the symptoms of drug-induced lupus improve within a few weeks, and blood tests reveal a return to their natural state. There is no specific test to identify which drugs may be the cause of the condition, except for noting improvements in symptoms as a person stops and starts particular medications. This can be challenging, especially if a person takes several different medications. Choi, Rao and colleagues next want to expand their efforts into developing novel treatments for lupus patients.

Lupus can be difficult to diagnose because its signs and symptoms often mimic those of other ailments. The most distinctive sign of lupus — a facial rash that resembles the wings of a butterfly unfolding across both cheeks — occurs in many but not all cases of lupus. This test might also be done to rule out other conditions that cause rashes.

It has been estimated that 10% of cases of SLE are drug-induced and, in one case series, 20% of biopsy-proven cases of subacute cutaneous LE were drug-induced. Intrinsic genetic susceptibility may help explain why some patients experience DILE as a reaction to drug therapies, whereas others do not. In the United States, the population is almost evenly divided between those who are fast and those who are slow acetylators. Those with slow rates have a higher prevalence of DILE than those with faster rates. In contrast, SLE affects individuals with slow and fast rates approximately equally. DILE has been observed with increased frequency in association with human leukocyte antigen (HLA)‒DR4.

The medications and other exposures implicated in DILE and flares of SLE produce autoantibodies more often than systemic autoimmune symptoms. Despite these commonalities, research suggests that DILE and SLE have separate and distinct mechanistic pathways. Which drug characteristics cause the autoantibody formation is unclear, but several theories have been proposed. Most patients with DILE have 1 or more clinical symptoms of SLE, such as arthralgias, lymphadenopathy, rash, and fever, and have had no prior history of autoimmune disease.

In these atypical cases, we recommend trying a course of treatment of serum sickness, such as a course of antihistamines or steroids and—in patients who do not improve on this regimen—refer the patient to a rheumatologist for further evaluation. A large number of proton pump inhibitor (PPI)-induced subacute cutaneous lupus erythematosus cases have been reported, suggesting a shift over time in the spectrum of drugs implicated in DILE. Twenty-two articles comprising 29 DILE case reports published within the last 2 years are summarized in this review, including 12 (41.4%) systemic DILE. Antitumor necrosis factor (anti-TNF) drugs were the most frequently (41.7%) reported to introduce systemic DILE in these cases.

Chemotherapeutic drugs were the most common drug class (54.5%) involved in subacute cutaneous lupus erythematosus, with an observed higher incidence in female patients. Enhanced neutrophil extracellular trap (NET) formation induced by procainamide and hydralazine could be a new mechanism contributing to the pathogenesis of DILE. It is widely accepted that genetic susceptibility plays a role in development of DILE. Drugs such as procainamide, hydralazine and isoniazid contain a structure of aromatic amines or hydrazines, and are predominantly metabolized by acetylation utilizing N-acetyltransferase enzymes [13]. Interestingly, the risk of developing DILE is about the same in patients with the same serum concentration of procainamide, regardless of the acetylator phenotype [64].
