What Doctors Treat hATTR Amyloidosis?

Hereditary transthyretin (hATTR) amyloidosis is a rare, progressive condition that results from a genetic mutation. This mutation leads to the production of unstable proteins that misfold and accumulate as amyloid deposits throughout the body. The complex nature of hATTR amyloidosis means that its treatment requires specialized and coordinated care. This article outlines the type of medical professionals involved in managing this condition.

Understanding hATTR Amyloidosis

Hereditary transthyretin amyloidosis occurs when the liver produces an abnormal transthyretin (TTR) protein due to a genetic mutation. These misfolded proteins, called amyloid fibrils, deposit in various organs and tissues. The accumulation of these amyloid deposits can damage organ function and lead to a wide range of symptoms.

The disease can affect multiple organ systems, leading to diverse symptoms. For instance, it can cause heart-related complications such as an enlarged heart, irregular heartbeats, and heart failure. Nerve damage can manifest as numbness, tingling, and weakness, particularly in the hands and feet, or issues with the autonomic nervous system which controls involuntary bodily functions like digestion, blood pressure, and sweating. Kidney involvement can lead to problems like foamy urine due to increased protein, and the digestive system may experience issues such as diarrhea, constipation, nausea, and unintended weight loss.

Key Medical Specialists

Given the varied ways hATTR amyloidosis can affect the body, a range of medical specialists is involved in its management. Each specialist focuses on the specific organ systems impacted by the disease.

Cardiologists play a central role in managing heart-related complications, particularly amyloid cardiomyopathy. They assess and address issues such as irregular heartbeats, heart failure, and fluid buildup in the body.

Neurologists focus on the effects of hATTR on the nervous system, including peripheral neuropathy (numbness, tingling, and weakness) and autonomic neuropathy (problems with blood pressure, digestion, and bladder control). They help manage symptoms like carpal tunnel syndrome and difficulty walking.

Gastroenterologists address digestive system issues such as chronic diarrhea, constipation, early satiety, and unexplained weight loss, which are common in hATTR amyloidosis due to autonomic nerve involvement. Nephrologists manage kidney involvement, monitoring kidney function and addressing issues like proteinuria and kidney damage. Genetic counselors provide information on the inherited nature of hATTR amyloidosis, explain genetic testing results, and discuss family planning implications.

The Multidisciplinary Care Approach

Effective treatment for hATTR amyloidosis relies on a coordinated, multidisciplinary team approach. This integrated strategy helps manage the disease’s complex and multi-organ involvement.

Different specialists communicate and collaborate to develop a comprehensive treatment plan tailored to the individual patient’s needs.

This team often includes cardiologists, neurologists, gastroenterologists, nephrologists, and genetic counselors. Additionally, other healthcare professionals contribute to supportive care, aiming to improve quality of life and manage symptoms. These include physical and occupational therapists for mobility, dietitians for nutrition, social workers for support, and palliative care specialists for symptom relief. The primary care physician also coordinates overall health management.

Role of Specialized Centers

Patients with hATTR amyloidosis can benefit significantly from receiving care at specialized amyloidosis centers or academic medical centers. They typically house the necessary multidisciplinary teams under one roof, fostering seamless collaboration among specialists.

Specialized centers often possess extensive experience with hATTR amyloidosis, leading to earlier and more accurate diagnoses. They may also provide access to the latest treatment advancements and clinical trials, offering patients options that might not be available elsewhere.
