Understanding GBS and MCTD: A Patient's Journey
A 44-year-old woman, who stands 5 feet 8 inches tall and weighs 155 pounds, presents a medical history marked by supraventricular tachycardia (SVT). To summarize her experience, she received a flu shot at the end of November, after which she began experiencing a range of systemic symptoms. It started with an enlarged thyroid, severe headaches, and excruciating back pain. This was soon followed by widespread nerve pain and optic neuritis. After several weeks and a few orthopedic evaluations, she consulted with a neurology nurse practitioner (NP) who suspected a link to the vaccination, yet refrained from diagnosing it as Guillain-Barré Syndrome (GBS). An MRI of the brain was conducted to eliminate other potential conditions, yielding normal results with a follow-up planned for six months later. Determined to believe that her condition would improve, she found herself several months later with minimal progress and an array of dysautonomia symptoms, including ongoing SVT, blurred vision, fluctuations in blood pressure, and tinnitus. Although she experienced some reduced reflexes early on, she has not faced muscle weakness or coordination issues. Her new primary care physician (PCP) performed laboratory tests, which revealed positive results for antinuclear antibodies (ANA) and RNP antibodies, while other checks returned negative. Her NP is considering the possibility of mixed connective tissue disease (MCTD), but she remains convinced that her symptoms align more closely with a variant of GBS. Notably, she does not exhibit many of the usual symptoms associated with MCTD. With weeks, if not months, to wait for appointments with rheumatology or neurology, the uncertainty is becoming increasingly frustrating for her. She seeks insights from others on whether RNP antibodies are frequently found in cases of GBS, as her research suggests this occurs approximately 36% of the time. She is pondering whether her PCP should also check for GQ1b antibodies or perform an ANA test using fluorescence microscopy. As a knowledgeable nurse, she feels somewhat out of her depth in this situation, eager to address some of these questions while waiting for further medical guidance.

It's understandable to feel overwhelmed and frustrated by your health journey, especially with the uncertainty surrounding your symptoms and possible diagnoses. Here's a summary and actionable insights based on your situation.
Main Points:
- Your symptoms post-flu shot and the findings of positive RNP antibodies raise questions about both Guillain-Barré Syndrome (GBS) and mixed connective tissue disease (MCTD).
- RNP antibodies do appear in some patients with GBS, but GBS is characterized more by subtype-specific antibodies, often not including RNP.
- It makes sense to consider further tests, such as checking for GQ1b antibodies and performing an ANA test using fluorescence microscopy if you haven't already.
Explanation:
Guillain-Barré Syndrome is an autoimmune disorder where the immune system attacks the nerves, often triggered by infections or vaccines. While some antibodies (like GQ1b) are more closely associated with GBS, RNP antibodies can point towards a connective tissue disease, such as MCTD, which shares symptoms like fatigue and dysautonomia. However, the presence of these antibodies does not rule out GBS, but it complicates the diagnosis.
Next Steps:
-
Consultation Follow-Up: While waiting for your appointments, keep a detailed record of your symptoms, noting their onset, duration, and any changes. This can be insightful when discussing your case with healthcare providers.
-
Discuss Testing Options: Prepare a list of your questions for your PCP regarding further antibody testing, particularly:
- GQ1b antibody testing to evaluate the possibility of GBS.
- An ANA test using fluorescence microscopy for a clearer picture regarding autoimmune conditions.
-
Symptom Management: Focus on managing the symptoms you can control:
- Stay hydrated and maintain a balanced diet to support your overall health.
- Engage in gentle exercises (if approved by your PCP) to help with blood circulation and alleviate some symptoms of dysautonomia.
-
Stay Informed: Continue educating yourself on both GBS and MCTD. Knowledge can empower you to have more productive discussions with your healthcare team.
-
Support System: Connect with support groups (online or local) for individuals with similar conditions. Sharing experiences can provide emotional support and practical advice.
It's normal to feel uncertain and concerned in your situation. Remember that you're advocating for your health, which is crucial. If you experience any new symptoms or significant changes, reach out to your healthcare provider sooner. Keep focused on your health journey, one step at a time.

Inquiry About Dental Procedures Before Major Surgery
Recently, my mother made a sudden decision to undergo a total dental extraction. She had her upper teeth removed approximately two weeks ago, and just yesterday, the lower ones were taken out. She is slated for a pre-operative assessment on Monday morning, ahead of a significant back surgery scheduled for Tuesday, which may last between eight to ten hours and necessitates intubation. I am curious about the likelihood that her doctor might postpone the surgery due to her recent dental procedure. This concern is heightened as we have booked a hotel and my husband has arranged to take two days off work for this event. Although I am still within the timeframe to cancel our hotel reservation, I am hesitant to do so if her surgery is still on track. To give a bit more context, my mother is a 54-year-old Caucasian woman, standing 5'6" and weighing 160 pounds. She does not consume alcohol, has been a potential smoker, and recently (a few months back) ceased using drugs (meth) as mandated by drug court. As far as I know, she isn’t currently prescribed any medications, apart from possibly antibiotics and Lortabs following her tooth extractions.
Abrupt Onset of Eye Discomfort
I’m a 23-year-old male with a history of slight near-sightedness but no other significant eye problems. About three days ago, I woke up to find that my eyes felt intensely painful, similar to the sensation one experiences after a lack of sleep. Although I've been getting ample rest each night, this discomfort hasn't subsided. Both eyes are affected equally without any redness, burning sensations, or visual disturbances. The soreness is quite pronounced, making it challenging to concentrate on everyday activities.
My Relationship with Milk Consumption
For nearly two decades, I have predominantly relied on milk as my primary source of hydration, consuming around five liters daily. Although I recognize that this reliance might not be the healthiest choice, my low appetite has perpetually left me underweight. In the past, I attempted to transition to drinking water; however, I noticed a concerning drop in weight along with persistent fatigue. My inquiry is whether there exists a more nutritious method to obtain calories without resorting to solid foods, and ideally, without incurring high costs?
When Can I Expect to Drive Again?
I’m a 35-year-old who suffered a spiral fracture in my right leg affecting both the fibula and tibia. Five weeks post-surgery, I've begun my rehabilitation journey, having undergone physical therapy for three weeks now. I’ve noticed that my leg is beginning to regain sensation, with improved control over my ankle and feeling returning to the sole of my foot. Given this progress, what is a realistic timeframe for when I might be able to drive safely once more?
Seeking Help for Ongoing Health Issues
I am reaching out in desperation for assistance! I'm wondering if anyone else has encountered similar health concerns or could recommend medications or specialists I should consider consulting. I'm truly at a loss and need guidance. As a 23-year-old male vegetarian weighing around 48 kg and standing at 5’4”, I have struggled with being underweight since my childhood. This condition has left me feeling utterly drained and overwhelmed. I’m eager to make a change but feel lost regarding where to begin or which healthcare professional to consult. In my youth, I was diagnosed with asthma, which has significantly improved; however, I continue to deal with low immunity, as I frequently catch colds and coughs from minor exposure to cold environments. Additionally, I’ve noticed that for the past few years, my body temperature feels abnormally high compared to those around me. I experience heat more acutely than my peers. Previously, I was quite active and could walk 4–5 kilometers daily without difficulty. Nowadays, even a short walk of 1–2 kilometers or climbing a few flights of stairs leaves me out of breath and exhausted. Even on days of little physical exertion, I feel weak and lethargic, as though all my vitality has been drained. My appetite has always been low, despite my efforts to increase it. I struggle to consume what would be considered an average meal for someone my age. Just two chapatis or a small bowl of rice or lentils fills me up completely, and attempting to eat more causes discomfort. I often find it perplexing how others manage to eat such larger portions. Dining out has become a challenge for me since even half a plate feels overwhelmingly full. Being extremely slender has made it difficult to find clothing that fits well and has adversely impacted my confidence over the years. For around 15 years, I have hesitated to take photographs of myself. Social and professional circles often regard me as younger than I am, sometimes even as a child, which has contributed to my feelings of invisibility and insecurity. My sensitivity to heat has intensified over the last few years. In seemingly normal room temperatures, I start sweating profusely while those around me remain comfortable. During cold weather, even in temperatures as low as 8°C, I don’t wear warm clothing, as I sweat excessively and feel anxious about overheating. The discomfort can escalate to a point where I feel faint from the heat. In my workplace, where the air conditioning is set at a standard temperature, I find it challenging. I begin to sweat visibly, leaving my clothes damp and prompting coworkers to inquire about my wellbeing. I often feel breathless and anxious that I might collapse if I remain there too long. This makes it very difficult to stay at the office or use public transportation, as even air-conditioned buses can feel uncomfortably warm to me. Over the past year, my situation has deteriorated further. I can no longer tolerate hot or even mildly spiced home-cooked meals, which I used to enjoy without issues. Now, even mildly spiced foods lead to excessive sweating, reddening of my face, and an intense burning sensation in my mouth, akin to consuming overly spicy dishes. As a result, my food intake has diminished even more. I often face ridicule for my dietary limitations, and I’m growing weary of trying to explain my condition, especially when my own family doesn't fully grasp the depth of my struggles, which adds to my distress. I am sharing my story because I truly need help. I wish to identify the underlying issues with my health and seek proper medical attention. If anyone has experienced similar problems or can recommend a suitable type of medical professional to consult, I would greatly appreciate your guidance and support during this challenging time. Thank you. 😭
