There are more things in heaven and earth then I dreamt of in our philosophy; and more things that we encounter in our offices than we can find in PubMed’s> 20,000.000 citations. A 35-year-old woman was started on a second course of isotretinoin for recurrent acne. Her previous treatment was two years earlier and was uneventful. A few weeks after restarting the medication, at a dose of 0.5 mg per kilogram per day, she experienced some malaise, muscle aches, and mild joint pain. There were no new skin findings. She called me and I allowed that I had not heard of these symptoms with isotretinoin, but ordered a CBC and an ANA. The CBC was normal, but the ANA was positive at 1:640 with a homogeneous pattern. A PubMed search retrieved no references to drug-induced lupus and isotretinoin. However, a Google search found some anecdotal reports and a few cases of suspected DIL with isotretinoin (there were 5 alleged cases of DIL out of 27,831 self- reported isotretinoin side-effects) eHealthme. With regards to our patient, I am going to repeat her ANA and obtain an anti-histone antibody test. If the ANA is still positive I will have her stop the isotretinoin and repeat the lab studies after 2–3 weeks. Should this likely be DIL then I think it is important that there be a report in the medical literature as undoubtedly other patients will experience this.
The Anti-Histone Antibodies Test is a blood test that detects antibodies against histones, and proteins associated with DNA in the cell nucleus. It helps in diagnosing autoimmune conditions like drug-induced lupus or certain types of arthritis. Anti-Histone Antibodies Test Here are the basic details of the Anti-Histone Antibodies Test. Test Name Anti-Histone Antibodies Test Also Known As Histone Antibodies Test Type Blood Test Purpose Detect Autoimmune Disorders Sample Type Blood Sample Preparation None Fasting Not Required Gender All Age Group All Normal Value Negative (No Antibodies Detected) Reporting Time Within 24 hours Cost 1000-2000 INR* *Price range may vary as per location, lab type, and procedure of lab test. Anti-Histone Antibodies Test Means The Anti-Histone Antibodies test measures the presence and concentration of antibodies against histones in a person's blood. Histones are proteins associated with DNA in the cell nucleus and play a role in gene regulation. This test is crucial for diagnosing autoimmune diseases like systemic lupus erythematosus (SLE) and drug-induced lupus. Results are reported as the presence or absence of these specific antibodies and their concentration, if present. Abnormal results may indicate autoimmune disorders affecting the connective tissues. The test aids in diagnosing and monitoring autoimmune conditions. Anti-Histone Antibodies Test Purpose The purpose of the Anti-Histone Antibodies Test is to: Diagnose autoimmune diseases like systemic lupus erythematosus (SLE). Detect the presence and concentration of anti-histone antibodies. Monitor autoimmune disorders affecting connective tissues. Assess treatment effectiveness and disease progression. Aid in the management of autoimmune conditions. Facilitate targeted medical interventions. Anti-Histone Antibodies Test Preparation Here is the basic preparation for the Anti-Histone Antibodies Test. Before Test No specific dietary restrictions. Inform the healthcare provider of any medications or medical conditions. Understand the test's purpose and its relevance to autoimmune disease diagnosis. During Test No specific actions are required during the test. After Test Follow any post-test instructions given by the healthcare provider. Discuss the results and their implications for autoimmune disease diagnosis and management. Be prepared to follow up with additional tests or treatments as recommended. Anti-Histone Antibodies Test Procedure Here is the basic Anti-Histone Antibodies Test Procedure. The Anti-Histone Antibodies Test involves collecting a blood sample from the patient, typically from a vein in the arm. The collected blood is processed in the laboratory to isolate the serum. The laboratory technician uses specific techniques, such as enzyme-linked immunosorbent assay (ELISA), to detect the presence and concentration of anti-histone antibodies. Test results are reported as the presence or absence of these antibodies and their concentration if detected. The procedure is crucial for diagnosing autoimmune diseases affecting connective tissues. Accurate results assist in managing autoimmune conditions effectively. Anti-Histone Antibodies Test Result Here is the basic reading of the Anti-Histone Antibodies Test results. Check the test report for the presence or absence of anti-histone antibodies. A positive result indicates the presence of these antibodies. The concentration is typically not provided in a binary result, but the presence suggests possible autoimmune conditions affecting connective tissues. Discuss the results with a healthcare provider for further evaluation and management. Anti-Histone Antibodies Test Positive Result Report Format Anti-Histone Antibodies Positive Test Report Anti-Histone Antibodies Test Positive Result Report Anti-Histone Antibodies Test Negative Result Report Format Anti-Histone Antibodies Negative Test Report Anti-Histone Antibodies Test Negative Result Report Anti-Histone Antibodies Test Normal Range Here is the normal range of the Anti-Histone Antibodies Test Value Explanation of Results <1.0 Negative 1.0-1.5 Weak Positive 1.6-2.5 Moderate Positive >2.5 Strong Positive Anti-Histone Antibodies Test Interpretation Here is the Interpretation of the Anti-Histone Antibodies Test. Test Result Interpretation Positive Elevated antibodies Negative Antibodies absent Anti-Histone Antibodies Test Positive Results Here are the potential causes of Anti-Histone Antibodies Test Positive Results. Potential Causes Description Drug-Induced Lupus Some medications, such as hydralazine and procainamide, can lead to drug-induced lupus with positive anti-histone antibodies. Idiopathic or Autoimmune Disorders Positive results may be associated with autoimmune diseases, such as systemic lupus erythematosus (SLE) or idiopathic cases. Inflammatory or Connective Tissue Diseases Conditions like rheumatoid arthritis or mixed connective tissue disease may lead to positive results. Infections Certain infections, like viral hepatitis, may trigger the production of anti-histone antibodies. Environmental or Occupational Exposure Exposure to environmental toxins or occupational hazards can lead to positive anti-histone antibodies. Medications Some medications used to treat conditions like cancer and autoimmune diseases can induce the production of anti-histone antibodies. Positive anti-histone antibody results typically warrant further investigation to determine the underlying cause and to guide treatment decisions. A healthcare professional should be consulted for a comprehensive evaluation. Anti-Histone Antibodies Test Negative Results Here are the potential causes of Anti-Histone Antibodies Test Negative Results. Potential Causes Description Absence of Autoimmune Conditions Negative results may suggest the absence of autoimmune diseases associated with anti-histone antibodies. No Drug-Induced Lupus A lack of histone antibodies may indicate that drug-induced lupus is not present. No Infections The absence of certain infections that can trigger anti-histone antibody production. No Environmental or Occupational Exposure The individual may not have been exposed to relevant toxins or occupational hazards. Medication History Negative results may be due to the absence of medications known to induce anti-histone antibodies. Healthy Immune System A well-functioning immune system may not produce anti-histone antibodies in the absence of relevant triggers. Negative anti-histone antibody results are typically reassuring, but further clinical evaluation may be necessary if the suspicion of autoimmune or drug-induced conditions remains. Consulting a healthcare professional is essential for proper interpretation and diagnosis. Specimen Requirements For Anti-Histone Antibodies Test Here are the specimen requirements for the Anti-Histone Antibodies Test. Specimen Serum Volume 1 ml Container Red-top tube or gel-barrier tube Collection Separate serum from cells within one hour of collection. Transfer to a plastic transport tube before shipping. Storage Refrigerate or freeze. Sample Stability Temperature Period Room temperature 14 days Refrigerated 14 days Frozen 14 days Causes for Rejection Hemolysis; icterus; lipemia; bacterial contamination. Anti-Histone Antibodies Test is Safe? The Anti-Histone Antibodies Test is safe, involving a routine blood sample collection conducted by trained professionals. The test's risks are minimal, with potential side effects limited to mild discomfort or bruising at the blood draw site. It is considered a safe diagnostic tool used for the detection of autoimmune conditions. When Do You Get Anti-Histone Antibodies Test Results? Anti-Histone Antibodies Test results are typically available within 24 hours, depending on the laboratory's processing speed. Patients can expect to receive their test results from their healthcare provider once the analysis is finished. Anti-Histone Antibodies Test Limitation Here is the basic limitation of Anti-Histone Antibodies Test. The presence of anti-histone antibodies does not confirm a specific autoimmune disease. Results may not capture fluctuations in antibody levels over time. Limited to detecting anti-histone antibodies and may not identify other relevant autoantibodies. Interpretation can be challenging due to variations in antibody profiles. Positive results require clinical correlation for a definitive diagnosis. Anti-Histone Antibodies Test Risk Factors Here are some of the risk factors of the Anti-Histone Antibodies Test. Risk factors may include autoimmune diseases like systemic lupus erythematosus (SLE). Medications or medical conditions that can cause drug-induced lupus. Previous exposure to drugs or environmental factors associated with lupus. Demographic factors may influence antibody prevalence, such as age and gender. Inaccurate results can occur if the test is not conducted correctly or interpreted in isolation. Doctor Recommendations After Anti-Histone Antibodies Test Result Here are the Doctor's recommendations or consult a specialist after the Anti-Histone Antibodies Test.

Raise awareness with these waterproof stickers! If using on products that need to be washed, please hand wash! There are four main types of lupus: systemic lupus erythematosus (SLE), discoid lupus erythematosus (DLE), drug-induced lupus, and neonatal lupus. Neonatal lupus can sometimes affect a child of a person with lupus, with most symptoms usually disappearing within six months of life. Drug-induced lupus is, as the name suggests, a lupus-like illness caused by certain medications. It causes SLE-like symptoms that are usually reversible. Discoid lupus erythematosus is a chronic inflammatory skin condition that causes sores and scarring, most commonly on the face and scalp, but can be anywhere. Sunlight can sometimes cause the sores to appear. Systemic lupus erythematosus is the most common type of lupus. It can affect many different parts of the body and can even lead to lupus nephritis, which is when lupus autoantibodies affect structures in the kidneys. On average, it takes people six years to get a lupus diagnosis. Purple is the awareness color for lupus.
Research funded by the Lupus Foundation of America has uncovered new ways to test for lupus.

Various drugs are known to cause musculoskeletal symptoms, such as arthralgias, myalgias, drug-induced lupus and serum sickness.1 In the rheumatology world, the most commonly recognized drugs that can cause musculoskeletal symptoms are hydralazine, minocycline, fluoroquinolones and, recently, the dipeptidyl peptidase 4 (DPP-4) inhibitor class of medications. Although beta blockers also have a noted side effect...

A 50-year-old female with a past medical history of bone tuberculosis diagnosed nine months ago was admitted in our infirmary for persistent fever with no evident cause. The patient was treated with isoniazid, rifampicin, pyrazinamide, and ethambutol for seven months and for the past two months, she was taking isoniazid and rifampicin. She went to our emergency room (ER) for back pain and fever that she had been experiencing for the last month. She was admitted with suspicion of disseminated tuberculosis that was never confirmed. Physical examination was unremarkable. Blood tests showed an elevation of inflammation parameters. A computed tomography (CT) scan of the chest showed a mild pleural effusion. She remained with fever during the three weeks in the infirmary while undergoing many other studies that were all negative. The back pain would change sides, and three consecutive thoracic radiographies showed a small-sized pleural effusion that was either predominantly right-sided or left-sided. Several differential diagnoses were considered in the process, namely an active infection, neoplasia, or autoimmune disease. The search for circulating lupus anticoagulant was positive. Antinuclear antibodies (ANA) were positive and the anti-histone antibody was strongly positive. At this point, we suspected a drug-induced lupus diagnosis, and isoniazid was discontinued. Following discontinuation of isoniazid, back pain and fever subsided and patient was discharged after one week. This case is a diagnostic challenge because of the rarity and symptom severity of isoniazid-induced lupus. Isoniazid rarely induced this lupus-like syndrome, with an incidence of considerably less than 1%.
Genentech, Inc. and Biogen Idec has announced that a Phase III study of Rituxan (rituximab) plus mycophenolate mofetil (MMF) and corticosteroids in patients with lupus nephritis did not meet its primary endpoint of significantly reducing disease activity at 52 weeks.
In contrast to ‘conventional’ neuro-inflammatory or neuro-immune diseases like multiple sclerosis, CNS involvement in systemic inflammatory disorders can be very difficult to recognise, and even more difficult to confirm. Vasculitis, lupus, sarcoidosis and other disorders all may involve the brain and/or spinal cord, and in each instance, presentation with exclusively neurological features is far from unknown. In most such disorders, there are no diagnostic clinical features; many of these diseases mimic each other. Once suspected, it is commonly the case that no tests are available that categorically prove the disease to be present—other than cerebral biopsy, and even this has limited sensitivity and clearly carries a certain risk. A number of investigations often considered valuable are neither sensitive nor specific, and are prone to over-interpretation. CNS inflammatory diseases may be aggressive, seriously disabling or even fatal—and yet most are highly treatable. Clinical nomenclature and definitions have not helped a complex field—many are at best confusing, and often wholly misleading. Vasculitis, for example, is neither a diagnosis nor a disease, but rather a histopathological description (intramural inflammation, often but not invariably with additional perivascular infiltrates, accompanied by necrosis of the blood vessel wall). Lupoid sclerosis, a term firmly embedded in the literature, probably does not exist; lupus vasculitis is a ‘diagnosis' in rather commonly usage, but in fact very rarely is it a useful or accurate description of CNS lupus-related disease. Nonetheless, progress in this difficult area is being made. Clinical scenarios when such disorders ought to feature in a differential diagnosis are better defined, and symptoms or signs that help raise suspicion of individual disorders may be putatively put forward (based in the main on lessons from internal medicine rather than neurology). Approaches to confirming CNS inflammatory diagnoses can be suggested, with increasing recognition of the limitations of investigative techniques. Finally, and admittedly again almost wholly informed by clinical research in systemic inflammatory disorders, rather than good quality clinical trials in patients with neurological disease, treatment regimes are improving. A brief overview of these changes will be presented.
