LUPUS & LYME — NEWPORT BEACH
Lupus Symptoms That Overlap With Chronic Lyme Disease
Lupus and chronic Lyme disease share many symptoms — fatigue, joint pain, rashes, brain fog. Learn the overlap and how to get tested in Newport Beach.
The Problem
Two Conditions, Strikingly Similar Symptoms
Lupus (systemic lupus erythematosus) and chronic Lyme disease share an unusually large symptom overlap: fatigue, joint pain, skin rashes, sensitivity to light, fevers that come and go, and cognitive symptoms often described as “brain fog.” This overlap is well-documented enough that Lyme disease is sometimes referred to as “the great imitator” — and lupus is one of the conditions it’s most often mistaken for, or found alongside.

The Diagnostic Gap
Why This Matters for Diagnosis and Treatment
Lupus is diagnosed through a combination of clinical criteria and specific antibody testing (like ANA and anti-dsDNA). These tests are well-established for lupus itself, but they don’t rule out a coexisting infection. If a chronic tick-borne infection is present alongside a lupus diagnosis — or driving lupus-like symptoms without a confirmed lupus diagnosis — it can mean:
- ●
Symptoms that don’t fully respond to standard lupus treatment
- ●
Flares that don’t follow a typical lupus pattern
- ●
A diagnosis of “probable lupus” or “lupus-like syndrome” that’s never been fully confirmed
The Mechanism
The Infection Connection
Chronic infections are increasingly discussed as potential triggers or aggravating factors for autoimmune activity, through a process called molecular mimicry — where the immune system’s response to an infection cross-reacts with the body’s own tissue. This doesn’t mean Lyme disease causes lupus, but it does mean ruling out an underlying infection is a reasonable step, particularly for symptoms that aren’t responding as expected.
Could this be Lyme?The Testing Gap
Why Standard Lyme Testing Often Falls Short
Standard Lyme testing (Western blot, standard ELISA) is frequently not sensitive enough to catch early-stage or persistent infection. This means a patient can have active Lyme disease and still test negative — leaving an infectious contributor to their symptoms undetected.
At Newport Integrative, we use the TickBorne Complete panel — combining PCR and antibody testing — to catch what standard testing often misses.
