Nourishing the Body: Medical and Nutritional Management of EPS

When Encapsulating Peritoneal Sclerosis (EPS) is diagnosed, the immediate goal is to stabilize the condition, ensure your body is strong enough to recover, and manage the symptoms. This process involves a transition in your dialysis care, intensive nutritional support, and an individualized medical approach to address inflammation and scarring ^[1][2].

Immediate First Steps: Transitioning Care

For patients actively on PD, a critical step is typically the transition away from Peritoneal Dialysis (PD) ^[3]. Because the dialysis fluid itself is a major contributor to the damage, your medical team will often move you to Hemodialysis to allow the peritoneal membrane to rest ^[4]. This transition is carefully managed, even if you are not currently experiencing a full bowel obstruction, to prevent further “hits” to the membrane ^[2].

Critical Safety Warning: Do NOT stop, alter, or taper your peritoneal dialysis on your own. Abruptly stopping PD without a medical plan can cause life-threatening fluid overload and severe uremia (a buildup of toxins in the blood). Your nephrology team must carefully supervise this transition.

Nutritional Support: The Center of Recovery

Malnutrition is one of the most significant risks in EPS. This occurs because the “cocoon” around your intestines restricts movement and causes obstructions, making you unable to tolerate adequate food intake ^[1]. Oral or enteral (tube) feeding is preferred whenever safe.

• Total Parenteral Nutrition (TPN): If your bowels are obstructed or cannot handle food, you may be started on TPN. This is a specialized liquid formula delivered directly into your bloodstream through a central vein ^[5]. TPN carries important risks—including bloodstream infections, thrombosis, liver complications, and metabolic abnormalities—so it is best managed by an intestinal-failure team or specialized dietitian ^[6].
• Bowel Rest: During an acute flare or obstruction, your doctors may recommend “bowel rest”—avoiding all oral food and drink—to reduce swelling and pressure in the intestines ^[7]. This must only be done under direct medical supervision, as you will need IV fluids and electrolytes.
• Gradual Transition: As the obstruction improves, you will slowly move from TPN to enteral nutrition (tube feeding) and eventually back to a soft or regular diet ^[8]. This process is carefully monitored by nutrition specialists to avoid refeeding syndrome, a dangerous shift in electrolytes ^[9].

Medical Therapy

Because EPS involves both active inflammation and permanent scarring, doctors often use an individualized approach to target these different phases. It can be difficult to tell which phase you are in, so treatments are frequently used together ^[1]. Evidence for these drugs is largely observational.

1. Corticosteroids (The Inflammatory Phase)

Drugs like prednisone or prednisolone are used off-label to dampen the “fire” of active inflammation in the abdomen ^[10]. Some observational research suggests that starting steroids early may help improve survival and reduce the severity of the disease ^[11]. These are often started at a high dose and then slowly tapered. Never stop steroids suddenly; they require a supervised taper ^[12].

2. Tamoxifen (The Fibrotic Phase)

Tamoxifen is traditionally a breast cancer drug, but in EPS, it is used off-label for its potential “anti-fibrotic” properties—its ability to possibly help modify or soften scar tissue ^[13].

• How it works: It is thought to block certain growth factors that tell your body to produce more collagen (scar tissue) ^[14].
• Evidence: Some observational registries have shown a trend toward better survival in patients who receive tamoxifen ^[4].

Crucial Safety Warning: Blood Clot Risk
Tamoxifen is known to be pro-thrombotic, meaning it significantly increases the risk of blood clots in the legs (Deep Vein Thrombosis) or lungs (Pulmonary Embolism) ^[15]. Seek immediate emergency care if you experience unilateral leg swelling, sudden chest pain, shortness of breath, or if you cough up blood. A reported case of EPS documented extensive blood clots and liver damage after eight months of tamoxifen ^[16].

If you have a history of clotting or a rare condition called calciphylaxis (calcium buildup in small blood vessels), your doctor may advise against tamoxifen, as it could worsen these issues ^[17].

Other Medical Options

Other drugs like mTOR inhibitors (sirolimus or everolimus) or Mycophenolate Mofetil (MMF) are sometimes tried ^[14]. These are potent immunosuppressants often used in transplant patients. However, the evidence for their use in EPS is currently limited to small case reports and is considered “low-certainty” ^[18][19]. Never change these doses without your transplant team’s explicit guidance.

Medical management is often a long-term commitment. Many centers recommend continuing therapy for several months as a practice pattern, as stopping too early is feared to lead to a relapse ^[20].
