Recognizing the Signs: Symptoms of Reynolds Syndrome

In Reynolds syndrome, symptoms arise from two different systems: your liver and your skin/vascular system. Because it is an overlap syndrome, you may experience a combination of signs from both Primary Biliary Cholangitis (PBC) and limited Systemic Sclerosis (SSc) ^[1][2].

Understanding these signs can help you monitor your health and have more productive conversations with your care team.

The Liver Component (PBC)

The symptoms of PBC are caused by a backup of bile in the liver due to the immune system attacking small bile ducts ^[3]. While many people are asymptomatic at first, the most common signs include:

• Pruritus (Itching): This is often one of the most bothersome symptoms. It is a deep, persistent itch that typically feels worse at night and does not usually come with a rash ^[4][5].
• Fatigue: This is a profound, “bone-weary” tiredness that isn’t always related to how much you’ve slept. It is a hallmark symptom of PBC ^[6].
• Jaundice: In more advanced cases, a yellowing of the skin or the whites of the eyes may occur due to a buildup of bilirubin (a yellowish pigment) in the blood ^[7].

The Skin and Vascular Component (CREST)

The systemic sclerosis side of Reynolds syndrome usually follows the CREST pattern, which stands for five distinct clinical signs ^[8]:

1. Calcinosis: Small, painful white calcium deposits that form under the skin, often on the fingers or other pressure points ^[9].
2. Raynaud’s Phenomenon: A condition where the small blood vessels in the fingers and toes overreact to cold or stress. The skin may turn white, then blue, and finally red as blood flow returns ^[8].
3. Esophageal Dysmotility: This occurs when the muscles in the esophagus (the tube connecting the throat to the stomach) don’t move correctly, leading to heartburn or difficulty swallowing ^[10].
4. Sclerodactyly: This refers to the thickening and tightening of the skin on the fingers and toes, which can make them look “shiny” or make it harder to bend them ^[8].
5. Telangiectasia: Small, red, thread-like spots on the hands, face, or inside the mouth caused by widened blood vessels ^[8].

How Symptoms Overlap

In Reynolds syndrome, these two sets of symptoms coexist, but they may not all appear at once. Most patients find that the Raynaud’s phenomenon or skin changes appear first, often years before liver symptoms like itching are noticed ^[1].

What to Watch For

Because this syndrome is an overlap, it is important to watch for how these systems interact. For example, while the skin thickening (sclerodactyly) is usually limited to the hands and face, doctors will monitor you for any internal changes, such as digestive issues or changes in your breathing ^[11][12].

Regular check-ups are essential because the liver symptoms (like itching) and the vascular symptoms (like Raynaud’s) are managed with different types of treatments. Your medical team will look at the “big picture” to ensure both conditions are managed effectively ^[13][2]. For more on how these are tested, see The Science of Overlap: Diagnosis and Biology.
