Exploring a 12-Year-Old's Immunological Challenges
Hello everyone! My son, who is 12 years old, is currently under the care of an immunologist to investigate a selective IgA deficiency he discovered during a coeliac disease screening. In addition to this diagnosis, he has undergone allergy testing, which revealed significantly high IgE levels and heightened eosinophil counts. He also manages asthma. What has everyone puzzled is a persistent petechial rash that appears on his ankles, feet, and shins every few weeks. Interestingly, his older brother also experiences this same rash, which began at around the same age. After extensive testing for him, doctors identified no irregularities, leading the hematology team to decide against further testing. While reviewing my son’s previous test results, the immunologist hasn’t pinpointed any clear issues beyond the allergies and IgA deficiency, prompting them to order a comprehensive array of blood tests. The results largely returned normal, except for a low complement C4 level, mild lymphocytosis with a typical CD4 to CD8 ratio, and raised eosinophils. As a librarian, I tend to dive into research as a means to cope with uncertainties. Therefore, I am reaching out to see if anyone here has insights or suggestions regarding this case. Currently, I’m inclined to consider Sjögren’s syndrome as a potential avenue of exploration.

It sounds like you're facing quite a complex situation with your son's health, including selective IgA deficiency, allergy issues, asthma, and a recurring petechial rash. While there are several factors at play, it's understandable to seek clarity and guidance amidst uncertainty.
Main Points
- Underlying Causes: The petechial rash, alongside the immune challenges, may suggest various potential causes that need monitoring.
- Further Investigations: Given your concerns, there may be merit in exploring other related conditions or factors.
- Observations and Management: Keeping a detailed track of symptoms and rashes could help in identifying triggers or patterns.
Explanation
-
Petechial Rash: Petechiae are small, red or purple spots on the skin that can occur due to bleeding under the skin. They may be associated with various conditions, including allergic reactions, infections, or platelet abnormalities. The fact that both your sons experience this raises the possibility of a familial or environmental factor.
-
Immunological Considerations: Selective IgA deficiency can affect the immune response, and while it may not directly cause the petechial rash, it could contribute to an overall heightened sensitivity, especially with the allergies and asthma present.
-
Complement C4 Level: A low complement level can indicate problems with immune function or inflammation and warrants observation, especially if symptoms develop.
Next Steps
-
Symptom Diary: Keep a detailed record of when the rash occurs, any associated activities, foods consumed, or environmental changes. This could help identify triggers.
-
Follow Up Testing: Consider discussing further testing for autoimmune conditions like Sjögren’s syndrome, especially if symptoms evolve. Requesting specific antibody tests could be worthwhile.
-
Consult with Allergist/Immunologist: Continue collaboration with your immunologist and discuss any concerns regarding the eosinophilia and its relationship to the rash. They may also suggest additional treatments or management strategies for asthma and allergies.
-
Monitor and Educate: Stay informed about IgA deficiency and related conditions. Understanding these can empower you and your son in managing potential health implications.
Engaging in research is a great way to feel more in control; however, balancing it with professional medical advice is crucial to avoid unnecessary worries. You’re doing an excellent job of advocating for your son’s health! Please feel free to reach out again if you have more questions or need further assistance.

Inadvertently Used My Dog's Gabapentin
Recently, I made a rather foolish decision by taking my dog's gabapentin. I previously used this medication for my own issues, but it's been several years since I last took it. My dog was prescribed a dose, and in a moment of confusion, I consumed 300 mg, mistakenly believing it was equivalent to what humans take. Now, I am regretting this choice, concerned that since it was intended for my dog, I may experience adverse effects. The packaging indicates gabapentin at a dosage of 100 mg, yet it does not provide detailed ingredient information. A bit about myself: I am a 24-year-old woman, standing at 5 feet 2 inches and weighing 130 pounds. Additionally, I take Lexapro on a daily basis and occasionally smoke. I would appreciate any guidance on what I should do next.

I've been wondering about a potential scoliosis diagnosis. How serious is this condition? Will it impact my growth in terms of height? Is there a possibility for treatment? What options are available to address this issue?
Elevated Heart Rate and Trembling Post Steam Bath
I recently had an experience that raised some concerns about my heart health. Despite not having any previously diagnosed heart conditions, I sometimes grapple with anxiety related to my heart. A recent medical check-up and blood work came back normal, which brought some relief. After a swimming session, I spent approximately 25 to 30 minutes unwinding in a steam room. However, upon exiting and moving to the shower, I noticed a dramatic spike in my heart rate, jumping from around 100 to 170 beats per minute as indicated by my smartwatch. This sudden elevation in heart rate left me feeling quite shaky. Fortunately, I was able to sit down, focus on calming myself, and avoided any fainting spells. In a short period of about three minutes, my heart rate decreased from the 160s back to 100. I frequently use the steam room without experiencing such a reaction previously. I can’t help but wonder if perhaps I didn’t hydrate adequately, consumed too much caffeine, or stayed in the steam room longer than usual. Could this episode indicate a more serious underlying issue, or was it just an isolated occurrence?
Are There Lasting Effects from Long-Term Use of Montelukast?
Hello everyone! To provide some background, I was prescribed montelukast at a young age—around 4 or 5 years old—continuing until I was about 10 or 11. During that time, I experienced significant levels of aggression. Unfortunately, none of the medical professionals we consulted suggested discontinuing the medication or indicated that my symptoms could have been related to its use. This has left me with some unresolved feelings so I’d rather not delve deeper into that right now. Currently, it has been some time since I stopped taking montelukast, but I find myself grappling with certain challenges. While I’m hesitant to elaborate unless absolutely necessary, I’m curious whether anyone knows about potential long-term side effects from prolonged use of this medication during childhood. Thank you so much for your insights! Much appreciated! <3
Food Bolus Lodged for an Extended Period
28-year-old female Currently taking Guanfacine, Prozac, and Lyrica. It’s been quite the rollercoaster for me these past two weeks! To give you some context, I’ve experienced my fair share of food getting lodged in my esophagus several times each week since I was in high school. Typically, it’s not a huge deal; I manage to induce vomiting and continue with my day. However, today was different. I took a single bite of a turkey sandwich, and ever since, I’ve been regurgitating saliva and the sensation of food being trapped persists. The food got stuck around 11 AM, and now it’s already 8 PM. What can I do to alleviate this predicament?
