Hypocomplementemia with Negative ANA Results?

Greetings to all! I’m a 26-year-old graduate student based in the USA, grappling with an escalation of chronic pain that has persisted since my early teenage years. Recently, I consulted a new rheumatologist who ran several tests because of my family’s autoimmune history—my mother has psoriatic arthritis, and my sister struggles with ankylosing spondylitis. During my last evaluation in 2022, my tests showed negative outcomes except for low levels of C3 (79 mg/dL) and C4 (15 mg/dL). My recent assessments mirrored these results: negativity for anti-dsDNA, anti-Sm, and ANA, alongside a normal CRP count, yet again with low C3 (now 85) and C4 (17). No additional tests were conducted, although x-rays of my pelvis and hands appeared normal. To provide more context, here are some ongoing symptoms I’ve experienced intermittently: - Hair shedding - Regular pink rashes on my cheeks, often accompanied by headaches behind my eyes (accompanied by mild fever) and a sore throat—sometimes the rash also appears on my nose - Dry skin, dry eyes, and dry mouth, occasionally resulting in mouth ulcers - Itchy, red, and swollen hands that feel warm, frequently disrupting my sleep—sometimes this inflammation extends to my feet and seems triggered by stress, heat, consumption of alcoholic beverages like champagne or wine (whereas others have no reaction), sun exposure, and fluorescent lights—I avoid using overhead lights at work as they are particularly bothersome. - Severe fatigue and mental fog—my level of disorientation warranted a drug test during a sleep study, despite never having consumed non-prescription substances - Muscle soreness and joint stiffness, particularly after prolonged walking or upon waking - Difficulty with writing and gripping objects; I have previously participated in occupational therapy and now utilize pencil grips similar to those intended for young learners! My once hypermobile hands are now prone to locking up. These symptoms intensify periodically, erratically worsening every few months for about a week, making it extremely difficult to rise each day and attend work. I am eager to discern whether my concerns have a psychological basis or if my physical ailments can be accounted for by existing conditions. I find it challenging to locate a healthcare professional willing to help me assemble the entire picture, especially since I have various other diagnoses that are relatively well-controlled. Currently, my diagnoses include: - Raynaud’s phenomenon - Moderate dry eyes - Chronic migraine without aura, intractable - Gastroparesis with slow intestinal motility (post-GPOEM surgery, which was quite effective!) - Mild intermittent asthma - Oral allergy syndrome - Severe seasonal allergies - Increased mast cells identified in intestinal biopsy - Neuropathic pain - Hypermobile Ehlers-Danlos Syndrome diagnosed in 2021 - Childhood eczema - Recurrent sinus and ear infections (though it’s been a while since I last experienced any illness) - Frequent urinary tract infections, often presenting blood clots or protein in the urine My medications are as follows: - Gabapentin, 1200mg each day - Meloxicam - Montelukast - Zyrtec (4 tablets daily) - Omeprazole - Famotidine - Hydroxyzine - Aspirin drops - Dulera inhaler - Monthly Emgality injection - Botox for migraines Thank you for any insights or guidance you can provide—I truly value your expertise! As a pharmacology PhD student entering my final year, the stress is amplifying my situation, and I hope to uncover some answers before graduating and embarking on my career.

Thank you for sharing your concerns and detailed history. Your symptoms and lab results indicate a complex situation that may intersect with autoimmune and rheumatologic issues. Here’s a concise summary of key points, an explanation, and actionable next steps.

Main Points:

1. You have low complement levels (C3 and C4) and negative results for common autoimmune markers (ANA, anti-dsDNA, etc.).
2. Your symptoms, including skin rashes, joint pain, and chronic fatigue, are likely linked to your existing diagnoses, particularly concerning the possibility of an autoimmune condition.
3. The challenge lies in piecing together your symptoms and test results, especially considering your family history of autoimmune disease.

Explanation:

Hypocomplementemia, or low complement levels, can be associated with various conditions, including autoimmune diseases like lupus or Sjögren's syndrome, though your negative autoimmune tests may suggest something else. The intermittent rashes, fatigue, dry eyes, and joint issues could stem from a few overlapping conditions, such as:

• Sjögren's Syndrome: Given your dry eyes, dry mouth, and systemic symptoms, this could be a factor worth investigating, even if initial tests were negative.
• Other Autoimmune Conditions: It's possible you have another rheumatologic condition not yet identified.
• Ehlers-Danlos Syndrome: Since you have hypermobile EDS, it can also cause widespread pain and soft tissue changes, complicating your other symptoms.
• Mast Cell Activation Syndrome: Increased mast cells and symptoms of urticaria (hives) could indicate mast cell issues, especially given your allergies.

Next Steps:

1. Symptom Diary: Start tracking your symptoms meticulously. Note occurrences, triggers (e.g., stress, sunlight, specific foods), and treatments you try. This documentation can be valuable for your healthcare team.

2. Seek a Specialist Perspective: Consider consulting a rheumatologist who specializes in complex cases or autoimmune diseases. Look for someone with experience in EDS or mast cell disorders, as they can explore potential connections to your symptoms.

3. Consider Re-evaluating Autoimmune Testing: Discuss with your specialist the possibility of more specific tests for autoimmune conditions, like Sjögren's syndrome markers (e.g., anti-Ro/SSA, anti-La/SSB), particularly given your dry eyes and mouth.

4. Manage Stress: Since stress exacerbates many of your symptoms, explore techniques like mindfulness, yoga, or gentle exercise, which can help alleviate some symptom intensity.

5. Medication Review: Regularly review your medications with a healthcare professional to ensure optimal management of symptoms. There might be alternative treatments or combinations that can better address your pain and cognitive fog.

6. Support Network: Engage with support groups or counseling if you feel overwhelmed. Connecting with others who have similar experiences can be therapeutic.

Your concerns are valid, and it’s important to advocate for comprehensive evaluations to address your symptoms effectively. Take these steps to empower yourself in managing both your health and your academic life. If you need any further clarification or support, feel free to reach out!
