Systemic Scleroderma

Scleroderma is not one disease — it is a coordinated systemic challenge. Lung, GI, vascular, renal, and skin each move on their own timeline. The synthesis is everything.

About Systemic Sclerosis

What we mean when we say Systemic Sclerosis.

Systemic Sclerosis (SSc), commonly called Systemic Scleroderma, is a rare autoimmune connective tissue disease characterized by vascular dysfunction, immune dysregulation, and progressive fibrosis of the skin and internal organs. It is classified into limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc) subtypes, each with distinct trajectories and complication patterns.

The clinical landscape spans Raynaud's phenomenon, digital ulcers, interstitial lung disease (the leading cause of mortality), pulmonary arterial hypertension, GI dysmotility (esophagus, gastric, small bowel, colon, anorectum), scleroderma renal crisis, and cardiac involvement. Each organ system requires its own surveillance protocol and intervention thresholds.

Standard care is anchored in rheumatology but inevitably requires coordination across pulmonology, GI, cardiology, nephrology, and vascular medicine. The synthesis is rarely complete.

Prevalence

Approximately 18.87 per 100,000 globally — roughly 1.47 million people worldwide. Strong female predominance.

Systemic Scleroderma is rarely missed at diagnosis — the skin findings, Raynaud's, and antibody patterns get the attention they need from rheumatology. The gap is in what comes after. Scleroderma is a coordinated systemic challenge across lung, heart, GI, kidney, and vascular domains, and most patients don't have a single clinician synthesizing across all of them.

  1. 01
    Interstitial lung disease is the leading cause of scleroderma mortality, and ILD progression risk stratification is the highest-leverage decision in many cases. Yet the surveillance — HRCT, PFT, DLCO trend — is inconsistently coordinated, and decisions about mycophenolate, tocilizumab, nintedanib, and autologous stem cell transplant are often made without systematic literature integration.
  2. 02
    Pulmonary arterial hypertension screening is uneven. Echocardiographic screening and right heart catheterization are condition-appropriate, but in practice they happen at variable intervals and often only after symptoms develop.
  3. 03
    GI dysmotility — esophageal, gastric, small bowel, colonic, anorectal — is nearly universal in systemic sclerosis and rarely fully characterized. Most patients are managed for esophageal reflux without evaluation of the rest of the GI tract.
  4. 04
    Scleroderma renal crisis prevention and Raynaud's / digital ulcer management are areas where evidence-based intervention is well-established but inconsistently applied. ACE inhibitor strategy, calcium channel blocker selection, and IV iloprost or bosentan considerations vary by center.
How we approach it

The Ternary Health approach to Systemic Scleroderma.

01

Coordinate the multi-organ surveillance plan — pulmonary, cardiac, GI, renal, vascular — across the specific subtype (limited versus diffuse cutaneous) and autoantibody profile, rather than evaluating each organ in isolation.

02

Stratify ILD progression risk specifically and audit the treatment selection — mycophenolate, tocilizumab, nintedanib, and autologous stem cell transplant — against current evidence and your specific trajectory.

03

Characterize the GI dysmotility picture fully — manometry, scintigraphy, and small bowel evaluation where indicated — rather than managing as esophageal reflux alone. The full GI picture matters for nutrition, medication absorption, and quality of life.

04

Build the integrated medication and supplement plan. Immunosuppression interacts with PAH-directed therapy, with vascular agents, with GI prokinetics, and with the dietary and supplement landscape patients are often navigating on their own.

Signals we look for

The Ternary Signal Library for Systemic Sclerosis.

Our Signal Library for Systemic Scleroderma codifies the specific patterns that matter — autoantibody and subtype findings, pulmonary and cardiac surveillance, GI dysmotility and renal markers, and vascular progression patterns. Your case is mapped against these signals; each present signal is identified and prioritized for your presentation.

Autoantibody & Subtype Classification
  • ANA pattern — centromere, nucleolar, speckled
  • Specific antibodies — anti-Scl-70 (topoisomerase I), anti-centromere, anti-RNA polymerase III
  • Limited versus diffuse cutaneous classification
  • Modified Rodnan skin score trajectory
  • Overlap features — myositis, Sjögren's, mixed connective tissue disease
Pulmonary & Cardiac Surveillance
  • HRCT — ILD pattern, extent, fibrosis distribution
  • PFT trend — FVC, DLCO, restrictive pattern characterization
  • Echocardiogram — RV function, PAP estimation
  • Right heart catheterization where PAH screening positive
  • Cardiac MRI for myocardial fibrosis where indicated
GI Dysmotility & Renal Markers
  • Esophageal manometry and pH studies
  • Gastric emptying study where suspected
  • Small bowel evaluation — SIBO testing, manometry where available
  • Anorectal manometry where fecal incontinence present
  • Renal function trend and hypertension monitoring for scleroderma renal crisis
Vascular & Raynaud's Progression Patterns
  • Raynaud's frequency, severity, and trigger pattern
  • Digital ulcer history and current status
  • Nailfold capillaroscopy findings where performed
  • Vasodilator and antiplatelet trial history
  • Calcinosis distribution and management considerations
The nine-stage workflow, applied

How a Systemic Sclerosis case moves through our workflow.

Our nine-stage workflow is the same for every engagement. What changes per condition is the content at each stage — the records we pull, the signals we apply, the specialists we map, the pathways we evaluate. Below, how your case specifically would move through each stage.

Stage 01 · 0–2
Qualification
Fit screen confirms diagnosed systemic sclerosis with subtype classification and autoantibody profile, access to prior workups, and current treatment status. ILD status and progression risk factors matter for case prioritization.
Stage 02 · 3–7
Intake & data aggregation
Records pull emphasizes HRCT and PFT trend, echocardiogram and any right heart catheterization, GI workup history, renal function trend, and complete immunosuppression and vasodilator history. Skin score and Raynaud's documentation collected.
Stage 03 · 7–11
Case structuring
Case schema populated. Subtype and antibody profile mapped to risk stratification. Multi-organ surveillance gaps identified. Treatment trajectory analyzed against current evidence.
Stage 04 · 11–15
Signal analysis
The Ternary Signal Library for systemic scleroderma is applied. Typical case activates 16–24 signals across antibody, pulmonary-cardiac, GI-renal, and vascular domains. Each signal evaluated for your specific presentation.
Stage 05 · 15–20
Evidence retrieval
Literature scan emphasizes the EUSTAR cohort data, ILD treatment trials including SLS-II, FocuSSced, and SENSCIS, autologous stem cell transplant trials (ASTIS, SCOT), PAH treatment landscape, and the GI dysmotility and renal crisis literature. Condition-specific Evidence Matrix refreshed.
Stage 06 · 20–25
Pathway mapping
Pathway map built across scleroderma-experienced rheumatology, ILD-specialized pulmonology, PAH-experienced cardiology, GI motility, and where indicated nephrology and vascular medicine. Specialists mapped from our Specialist Graph.
Stage 07 · 25–30
Synthesis & plan construction
Every option weighed against the three questions (Evidence × Personalization × Action), then prioritized and sequenced. Dependencies encoded as a directed graph — ILD progression risk informs treatment intensity, GI motility findings inform medication absorption considerations, renal status informs ACE inhibitor strategy, vascular findings inform Raynaud's and ulcer management.
Stage 08 · 30–34
Delivery & calibration
Findings call with attention to ILD treatment optimization, PAH and renal surveillance, GI and vascular management priorities. Your priorities and constraints update the plan before finalization.
Stage 09 · 34–64
Execution support
30 days of asynchronous follow-up through the typical scleroderma consultation sequence — scleroderma center rheumatology, ILD pulmonology, PAH cardiology, GI motility, and any indicated subspecialist consultations. Outcomes captured into the Ledger.

Frequently coexisting conditions

What we look for alongside Systemic Sclerosis.

Patients with Systemic Scleroderma frequently present with one or more of the following. Ternary reports evaluate the full picture rather than the condition in isolation.

Common questions — Systemic Scleroderma

What prospective Systemic Scleroderma clients ask most.

Should I be on mycophenolate, tocilizumab, or nintedanib for my ILD?
Depends on your antibody profile, FVC and DLCO trajectory, extent of fibrosis on HRCT, and prior treatment response. The trials — SLS-II, FocuSSced, SENSCIS — established each agent in different populations, and combination strategies are increasingly used. The Ternary report stratifies your ILD progression risk and audits treatment selection against current evidence.
Do I need to be screened for pulmonary hypertension?
Yes — annually at minimum if you have systemic sclerosis, more frequently if you have specific risk factors (limited cutaneous subtype, anti-centromere positive, decreased DLCO, advanced age). Echocardiographic screening followed by right heart catheterization when indicated is the standard. We audit your surveillance schedule against current recommendations.
What about autologous stem cell transplant?
An option for selected patients with early diffuse cutaneous disease, internal organ involvement, and treatment failure on conventional immunosuppression. The trials (ASTIS, SCOT) showed durable benefit at the cost of significant procedural risk. Candidacy is highly specific, the centers are limited, and the timing matters. The Ternary report evaluates whether ASCT consideration is appropriate for your case.
Do I need a confirmed diagnosis before applying?
A systemic sclerosis diagnosis with subtype classification and antibody profile is preferred. If you have Raynaud's plus a positive ANA and you're working through the differential, we can frame the evaluation pathway.
How do you handle the GI symptoms?
As a multi-organ workup, not as reflux alone. Esophageal manometry and pH studies, gastric emptying when indicated, small bowel evaluation including SIBO testing, and anorectal manometry for fecal incontinence are all part of the comprehensive scleroderma GI picture. We characterize the full tract and build the management plan accordingly.
