🧵 SAPHO Syndrome: The Skin–Bone Connection

1/
Ever seen acne + arthritis + osteitis in the same patient?
That strange cluster could be SAPHO syndrome — a rare, under-recognised autoinflammatory disorder.

Let’s break it down 👇
@IhabFathiSulima @DrAkhilX @CelestinoGutirr #MedTwitter #RheumatXImage 2/
🔤 SAPHO = Synovitis, Acne, Pustulosis, Hyperostosis, Osteitis
It’s not just an acronym.
It’s a unifying concept linking skin lesions + bone/joint inflammation. Image

A diagnostic puzzle every rheumatologist must know:
Adult-Onset Still’s Disease (AOSD) 👇 @IhabFathiSulima @DrAkhilX @CelestinoGutirr @RACC_UK @RheumNow
#Rheumatology #MedTwitterImage Tweet 2 (Basics)
🔑 What is AOSD?
•Rare systemic autoinflammatory disease.
•Triad: high fevers, evanescent rash, arthritis.
•Shares features with infections, malignancy, and autoimmune disease → often misdiagnosed.Image

🔥 🧵 Thread: “When Vasculitis Wears a Disguise”

Vasculitis is a shapeshifter.
It never walks into clinic saying, “Hello, I am vasculitis.”
Instead, it hides behind everyday symptoms.
Here are the common masks it wears 👇
@IhabFathiSulima @DrAkhilX @CelestinoGutirr #MedTwitter #RheumatXImage 1. Just a rash?
Palpable purpura on the legs may look like “allergy.”
But when it’s non-blanching, raised, and painful → small-vessel vasculitis should be suspected. Image

Here’s a thread on 10 general medicine lessons reinforced in rheumatology 🧵
Tweet 1:
Rheumatology isn’t “super-specialised.”
It’s general medicine… but deeper.
Every principle we learnt in MBBS comes back in rheumatology.

🌡️ Fever of unknown origin
Clues to think beyond infection:
• Rash that comes & goes
• Cytopenias
• Very high ferritin
• Hepatosplenomegaly
• Serositis

Sometimes, fever is inflammation wearing a disguise. Image

🧵: The Eye & Rheum: A Clinician’s Guide to Ocular Manifestations
Tweet 1:
1/10 👁️ The eye isn’t just the window to the soul—in medicine, it’s a window to systemic disease. Many rheumatic conditions write their first, or most severe, chapters on the ocular surface. A thread for clinicians on the critical link between Rheumatology & Ophthalmology. #RheumTwitter #OphthoTwitter #MedEd @IhabFathiSulima @Janetbirdope @DrAkhilX @ACRheum @RheumNowImage Tweet 2: Anatomy Primer
2/10 Before we dive in, let’s map the battlefield. Key structures where rheumatology makes its mark:
•Uvea: The pigmented middle layer (iris, ciliary body, choroid).
•Sclera: The tough, white outer layer.
•Cornea: The transparent front.
•Lacrimal Glands: The tear producers.Image

Early inflammatory arthritis(IA): the 3–3–3 rule
•Onset ≤3 months
•Morning stiffness ≥30–60 minutes
•≥3 swollen joints (MCP/MTP common)
If present, manage as IA: urgent rheum referral; NSAIDs if no contraindications.

Screen for: systemic (fever, weight loss, night sweats), vascular (new headache >50y, jaw/limb claudication), neuro/renal (hematuria, neuropathy).
Any present → same-week labs (CBC, ESR/CRP, creatinine, urinalysis) and escalate. Image

🧵 ANA (Antinuclear Antibody): What Every GP Needs To Know—2025 Guide

1/ What is ANA—and Why Test It?
ANA is a blood test that helps detect autoantibodies against cell nuclei, seen in autoimmune diseases like lupus, Sjögren’s, and more. It’s NOT a screening test for general complaints. Use it when history or exam genuinely points to autoimmune disorders
@IhabFathiSulima @DrAkhilX @CelestinoGutirr @Janetbirdope @SarahSchaferMD @NeuroSjogrens #MedTwitter #RheumatXImage 2/ Who Should Be Tested?
Test ANA only when you see signs such as:
•Unexplained, non-infectious joint pain/swelling
•Persistent rash, especially photosensitive
•Raynaud’s phenomenon
•Sicca symptoms (dry eyes/mouth)
•Multi-system symptoms (e.g., nephritis, serositis) Image

🧵 Red Flag Symptoms NOT to Miss in Rheumatic Diseases

1/ Systemic (Whole-Body) Red Flags
•Fever, unexplained weight loss, night sweats, loss of appetite, persistent fatigue
•Malaise or feeling generally unwell, lymph node swelling, new pallor
These often signal serious underlying inflammation, infection, or even malignancy.
@IhabFathiSulima @DrAkhilX @CelestinoGutirr @SarahSchaferMD @NeuroSjogrens #MedTwitter #RheumatologyImage 2/ Pain and Swelling Not Acting Like “Usual Arthritis”
•Acute, severe, or rapidly increasing joint pain (especially a single hot, swollen joint)
•Bone pain, deep/throbbing—not just joint tenderness
•Recurrent or migratory joint pain, especially with redness or heat. Image

🧵 Unlocking Rheumatology: What Every Joint, Patient & Clinician Should know👇

Tweet 1/5: The Anatomy of Arthritis
Ever wondered what sets a healthy joint apart from one with rheumatoid arthritis?
🔹 Healthy knees have smooth cartilage and clean bone architecture.
🔸 RA knees show swelling, inflamed synovium (the joint lining), and bone erosion—key targets for early intervention!

Stiff, aching joints first thing in the morning? You’re not alone.
For many with RA and similar diseases, getting out of bed is the hardest part. Targeted therapy and gentle movement can really help. Image

🧵 The Gut–Joint Connection: How Your Microbiome Influences Arthritis

🦠🤔 Could your gut bacteria be making your arthritis worse?
Emerging science says YES.
Your gut microbiome can shape your immune system… and may even trigger autoimmune joint disease.
Let’s connect the gut to the joints 👇
#MedTwitter #guthealthmatters @DurgaPrasannaM1 @nileshnolkha @IhabFathiSulima @DrAkhilX @CelestinoGutirr @drkeithsiau @SarahSchaferMDImage The microbiome’s hidden role
Your gut hosts trillions of microbes.
When balanced → they help digestion & immunity.
When imbalanced (“dysbiosis”) → they can mis-train the immune system, sparking inflammation far beyond the gut. Image

🧵 HBV Reactivation — How to Avoid Triggering a Silent Killer Before Steroids or Biologics
