About the Disease
IgG Heavy Chain Disease (Gamma chain disease) is classified as a neoplastic plasma cell disorder. Its hallmark is the hyperproduction of heavy chains from monoclonal immunoglobulins. The normal process of immunoglobulin production is disrupted, leading to the presence of fragmented heavy chains of immunoglobulin—an abnormal protein (paraprotein)—in the blood and urine.
The exact causes of gamma chain disease are not established. Researchers associate the pathology of IgG heavy chains with complications arising from certain systemic diseases.
The most common symptoms of IgG heavy chain disease include:
- recurrent infections;
- enlargement of lymph nodes, spleen, and liver;
- anemia;
- chronic fatigue and general weakness;
- loss of appetite, weight changes, and other gastrointestinal symptoms.
The subtype associated with gamma chain disease (IgG) is typically characterized by aggressive progression, with symptoms resembling malignant lymphoma. Laboratory tests reveal decreased levels of normal immunoglobulins, atypical circulating lymphocytes, leukopenia, eosinophilia, anemia, and thrombocytopenia. Approximately 25% of patients experience palatal swelling. In rare cases, the disease presents benignly without symptoms.

Treatment Methods for the Disease
Treatment of gamma heavy chain disease is specific and depends on the stage of the disease, the overall condition of the patient, and the presence of associated symptoms and conditions. The Ichilov clinic has developed clinical experience in treating this rare pathology. Currently, there is no standard treatment protocol, and therapy recommendations may vary depending on the progression of the disease in the individual patient.
Chemotherapy
Chemotherapy protocols similar to those used for treating other non-Hodgkin lymphomas and chronic lymphocytic leukemia are applied for the treatment of gamma heavy chain syndrome. The protocols recommend antitumor chemotherapeutic cytostatic alkylating agents and similar acting drugs.
Corticosteroids
Corticosteroids are used in the treatment of gamma heavy chain disease for their anti-inflammatory and immunosuppressive effects. Corticosteroids reduce inflammation by blocking substances that cause inflammatory reactions.
They suppress the immune system, which helps reduce the activity of altered immune cells and decrease the formation of pathological antibodies.
Corticosteroids can induce apoptosis in certain immune system cells, including B-lymphocytes, and reduce tumor mass by destroying cancer cells or decreasing their ability to divide and grow.
Monoclonal Antibody Therapy
Monoclonal antibodies are laboratory-created proteins that can specifically bind to antigens on the surface of cancer cells. They are used in the treatment of many diseases, including certain types of cancer and autoimmune diseases. In the context of treating IgG heavy chain disease, they are used to destroy the cells causing the disease.
The monoclonal antibody targets the CD20 protein, which is typically present on the surface of B-lymphocytes, including abnormal cells. The antibodies are designed to fully bind to specific molecules (antigens) on the surface of cells.
Monoclonal antibodies can be used as guides to deliver toxins, drugs, or radioactive elements directly to cancer cells, minimizing damage to healthy cells.
Combined Immunochemotherapy
Combined immunochemotherapy is a treatment strategy that combines the use of monoclonal antibodies (immunotherapy) with chemotherapeutic agents. In the case of gamma heavy chain disease, this approach can enhance therapeutic effectiveness by targeting cancer from multiple directions simultaneously.
The method is based on synergistic action, where immunotherapy combined with chemotherapy enhances each other's effectiveness. Monoclonal antibodies can facilitate access for chemotherapeutic agents to cancer cells or even make cancer cells more sensitive to chemotherapy.
Stem Cell Transplantation
In some cases, allogeneic hematopoietic stem cell transplantation may be considered, especially in young patients with severe disease progression.

Diagnostic Methods for the Disease
The diagnosis of IgG heavy chain disease is a comprehensive process. It includes numerous diagnostic activities, the main goal of which is to identify fragmented free monoclonal IgG chains in urine and blood. Most often, three working days are required to establish a diagnosis.
First Day
The doctor collects a detailed medical history, including family history and information about current symptoms. A physical examination is conducted, during which signs indicating chronic infections, enlarged lymph nodes, liver, or spleen are identified.
Second Day
Laboratory blood tests
- Complete blood count to detect anemia or other abnormalities.
- Biochemical blood test to detect changes in protein levels, liver, and kidney function.
- Immunoelectrophoresis or immunofixation electrophoresis of serum to detect abnormal immunoglobulins or their fragments.
- Measurement of quantitative immunoglobulin levels to determine specific deficiencies.
Urine tests
- For the presence of Bence-Jones protein.
- Urine electrophoresis to detect paraproteins.
Radiological studies: X-ray, CT, or MRI to assess the condition of internal organs, the presence of tumors, or enlarged lymph nodes.
Biopsy and histological analysis
- Tissue samples are taken, most often from lymph nodes, bone marrow, or other affected organs.
- If necessary, immunohistochemical analysis is performed to detect abnormal proteins.
Molecular genetic studies to identify genetic mutations or cellular anomalies that may be associated with the disease.
Third Day
Confirming the diagnosis requires a comprehensive analysis of the results from all examination methods. Due to the rarity of the disease, the individual nature of the symptoms, and the lack of a unified approach to therapy, a team of doctors at the Ichilov clinic works on developing a treatment strategy. Hematologists, oncologists, and radiologists thoroughly evaluate the data set to clarify the diagnosis and formulate a treatment plan.
- Computed Tomography
- Magnetic Resonance Imaging (MRI)
- X-ray
- Biopsy and Histological Studies
- Blood Biochemistry
How Much Does Treatment Cost
Gamma heavy chain disease is a rare condition that requires a strictly personalized approach to diagnosis and therapy. The cost of the program at the medical center depends on the number and complexity of diagnostic and therapeutic procedures. The price is influenced by the reputation and qualifications of the treating physician, as well as the need to involve external experts.
Call the phone number, and a professional medical coordinator will assist you in navigating the application process for treatment, advise on where to find reviews about the clinic and specific departments. You can ask questions regarding therapy, financial, and logistical issues in the online chat or through a special form on the website.
