Understanding Antibodies and Drug Allergies: Is There a Connection?
A 27-year-old female patient with a medical background that includes Crohn's disease and allergies to several biologic treatments (specifically Humira, Remicade, and now Stelara), who also underwent IPAA surgery, presents an interesting dilemma. This inquiry delves deeper into topics typically addressed in more general discussions, but let's us focus on the relevant details. I currently administer Stelara for my inflammatory bowel disease and have been on it for an extended period. However, recent symptoms, particularly hives, prompted me to undergo testing for antibody levels associated with the medication. The results revealed a high production of antibodies against Stelara. My primary concern revolves around the relationship between the presence of antibodies and allergic reactions. I find myself perplexed since, in past experiences, I was advised to discontinue medication when elevated drug antibodies were detected, with the understanding that these antibodies were indicative of an allergy—particularly considering that the reactions I've experienced have been similar to hives encountered previously.

It's understandable to be concerned about the relationship between drug antibodies and allergic reactions, especially given your medical history with Crohn's disease and previous allergic responses. The presence of high levels of antibodies against Stelara suggests your body is reacting to the medication, which can be linked to an increased risk of allergic reactions, such as hives.
Explanation
Antibodies are proteins produced by your immune system in response to what it perceives as foreign substances, including medications. In many cases, elevated drug-specific antibodies can indicate your body's potential to experience hypersensitivity or allergic reactions. Since you have experienced hives and have had to discontinue previous biologic treatments, your current situation with Stelara warrants careful management.
Next Steps
-
Document Symptoms: Keep a detailed log of any symptoms, including when they occur, their duration, and any potential triggers. This will help you identify patterns and communicate effectively with your healthcare team.
-
Review Medication History: Make a list of all medications you've taken (including biologics) and any allergic reactions experienced. This history is crucial for your healthcare team in assessing your current situation.
-
Evaluate Treatment Options:
- Discuss with your healthcare provider the possibility of discontinuing Stelara, especially given your elevated antibody levels and history of allergic reactions.
- Explore alternative treatments for your Crohn's disease that may have a different immunogenic profile, as you have had challenges with multiple biologic therapies.
-
Consider Allergy Evaluation: An evaluation by a specialist in allergies or immunology may be beneficial to better understand your reactions and guide future treatment choices.
-
Follow-Up Testing: Regular monitoring of your antibody levels and symptoms over time will give clearer insights into your response to Stelara or any new treatment.

Unexplained Urticaria Episodes
A 28-year-old woman, measuring 158 cm and weighing 72 kg, has been experiencing episodes of urticaria for the past month without any obvious cause. The issue began following a localized reaction to her migraine treatment, particularly the medication erenumab. Generally, she has minor reactions to this injection; however, the last two doses have led to significant flare-ups. Subsequently, she began to notice hives appearing sporadically, primarily without identifiable triggers. These episodes tend to intensify during the night but usually subside after taking cetirizine, an antihistamine. Additionally, she has known drug allergies to ciprofloxacin and penicillin. Recently, after taking cefpodoxime, she developed a rash within a few hours, although cefixime did not provoke any adverse reactions.
Rash on the Dorsal Side of My Hands
A 24-year-old male, standing 5'3" and weighing 125 pounds, is not currently taking any medications. While I do not smoke, I am often exposed to secondhand smoke from those around me, and I have recently spent time in an environment where a significant amount of unpleasant smoke is produced due to casting activities. For approximately three weeks, I have been experiencing a rash on the backs of both my hands. I initially became aware of it after working on my car's engine. The rash has led to dryness and itching, and I took a photo after my shower today, highlighting the redness that has become particularly noticeable. What are some effective treatments for this condition?
Understanding Symptoms of Salmonella: What to Do Next
My boyfriend, who is 26, experienced a fever that peaked at approximately 99.5°F yesterday morning. Thankfully, after resting and taking NyQuil, his fever subsided by this morning. However, he has been dealing with severe abdominal pain and persistent diarrhea since last evening, which has not shown much improvement. He has been making frequent trips to the restroom, nearly every hour throughout the night and again today. While I initially thought he might be improving since the fever has decreased, I became alarmed upon noticing bright red blood in his stool and on the toilet paper after he wipes. It has been around 40 hours since the fever began, and my concern has heightened now that blood has appeared. I’ve come across some online information suggesting these symptoms might be typical for salmonella infections, and I’m uncertain whether we should seek medical attention immediately or if it’s advisable to wait another day or two to see if his condition improves. I realize that consulting a doctor as soon as possible would be the best course of action. However, he currently lacks insurance, which makes him hesitant to get checked right away. Any guidance on this matter would be greatly appreciated, thank you.
Navigating Alcohol Challenges
My partner has recently developed issues with alcohol. Over the past year, he has been consuming significant amounts—roughly two bottles of distilled spirits each week, in addition to beer. A decade ago, he struggled with inhalants and even faced near-fatal consequences, but he had maintained sobriety until he turned to drinking. He believes he has plenty of time before the effects of alcohol will manifest. How long can he continue this way before it becomes a serious problem? He is a 53-year-old male, weighing 325 pounds, standing at 5 feet 11 inches, and he is currently on medication for hypertension. Although we plan to separate later this year, it’s clear that this situation will have an impact on our three children.
Persisting Chills Without Fever for Three Weeks After a Cold
Greetings! I'm a 30-year-old male dealing with a rather unusual situation, and I'm at a loss for what to do next. As mentioned in the title, I recently experienced a cold, which presented all the expected symptoms, but the chills have lingered. It's been around three weeks now, and I still feel cold despite wearing multiple layers and having the heater running in my home. Strangely, throughout this episode, I haven't had a single fever. I consulted my primary care physician, who also seemed puzzled by my symptoms. She has requested some blood tests which are scheduled for Monday, even though I had blood work done three months ago that showed normal results. Does anyone have insights into what might be causing this? I understand there could be various explanations, but I'm unsure how to proceed. I am not currently on any medications and don't have any known chronic health conditions. Any guidance on how to tackle this issue would be greatly appreciated! 🙏
