What do the kidneys do? Most people have two kidneys, one located on either side of the spine, just below the rib cage. Each kidney is about the size of a fist and weighs about 160 grams. Your kidneys are connected to your bladder by tubes called ureters. The kidneys carry out many Return vitamins, amino acids, essential functions, including: glucose, hormones and other Filtering the blood to get rid vital substances back into the of waste products from the bloodstream bloodstream Blood enters each kidney Keeping the salt (e.g. sodium through the renal artery and and potassium) and water passes through thousands of tiny content of the body constant filtering systems called nephrons (see Figure 1). Each nephron Controlling blood pressure contains a small cluster of Producing a number of specialised blood vessels called essential hormones the glomerulus and a tubule These functions are described which eventually connects to the in more detail below. bladder. Blood is passed through the glomerulus, which acts as a filter. Not all components that Waste products make up blood can pass through Healthy kidneys filter the the glomerulus.

Why does myeloma cause kidney disease? Myeloma kidney disease is a common complication of myeloma. Up to 20% of patients will have some degree of kidney disease at diagnosis and a further 40% will develop kidney disease at some point during the course of their myeloma. Myeloma kidney disease can and two identical light chains occur for a variety of reasons. (see Figure 2). The abnormal protein produced A healthy person produces by myeloma cells can damage a mixture of the different the kidneys by blocking the immunoglobulins made up of tubules. Other complications of different combinations of heavy myeloma, such as dehydration and light chains, each of which and a high calcium level plays a specialised role in fighting (hypercalcaemia), as well as infection. some of the drugs used in the treatment of myeloma, can also In myeloma, however, a large cause or contribute to myeloma amount of a single type of kidney disease. immunoglobulin (called paraprotein) is produced. Paraprotein plays no useful Light chains and paraprotein role in the body. In a healthy immune system, In about 20% of patients, the there are several different myeloma cells produce only light types of immunoglobulin (also chains (sometimes called Bence known as antibodies). Each Jones proteins) and no whole immunoglobulin is a Y-shaped immunoglobulins at all. This is structure and is always made up called ‘light chain’ or ‘Bence of two identical heavy chains Jones’ myeloma. Infoline: 0800 980 3332 9
Light chains are also elevated HEAVY LIGHT and measurable in the vast CHAIN CHAIN majority of myeloma patients that produce whole immunoglobulins (paraprotein). The excessive amount of light chains circulating in the bloodstream in myeloma can damage the kidneys. When they enter the kidney they are small enough to pass through the glomeruli and into the tubules. In the tubules, they often combine HEAVY LIGHT CHAIN CHAIN with another protein called Figure 2. Immunoglobulin structure Tamm Horsfall protein. The combination of lights chains with Tamm Horsfall protein can produce a big ©www.myeloma.org.uk protein design that sticks by www.blink.biz Figure: MUK02_Ig_structure-2COL in and blocks the tubule, rather than passing through into the urine. This can cause severe kidney damage. In addition to physically blocking the tubules, light chains are also directly toxic to the kidney, causing inflammation to the kidney tissues and worsening the damage. 10 www.myeloma.org.uk
Hypercalcaemia putting the kidneys under Bone is high in calcium and as it additional pressure. is broken down, a large amount For the majority of myeloma of calcium is released into the patients with any degree of blood. Myeloma commonly kidney disease at diagnosis, causes excess bone breakdown kidney function can be and this can cause high blood improved by keeping up a high calcium levels (hypercalcaemia). fluid intake.

strain on them if they are already damaged. Therefore bisphosphonates such as zoledronic acid (also known as Zometa®) are used with caution and often at lower doses – or temporarily stopped – in patients with myeloma kidney disease. Non-steroidal anti-inflammatory drugs (NSAIDs) – such as ibuprofen (Nurofen®), diclofenac and high-dose aspirin (300mg) – can be toxic to the kidneys and are therefore not recommended for myeloma patients. It is important that you inform your doctor about any non- prescription drugs, vitamins or supplements that you may be taking to ensure that they will not have any negative effects on your kidneys. 12 www.myeloma.org.uk
What are the symptoms of myeloma kidney disease? When the kidneys are not working properly, harmful toxins and excess fluids build up in the body, which causes symptoms. The symptoms of myeloma It is therefore important to kidney disease may include: mention any new symptoms to Thirst your doctor straight away, so the correct cause, or causes, can be Fatigue identified. Persistent headaches Patients with myeloma kidney Loss of appetite disease can have no symptoms.

Infoline: 0800 980 3332 13
Tests used to detect and monitor myeloma kidney disease The main test that is performed to diagnose and monitor myeloma kidney disease, and to determine the extent of any damage, is a blood test that measures the level of a molecule called creatinine. Creatinine is a waste product that is normally filtered out by the kidney and passed into the urine. A high creatinine level indicates that the kidneys are not working normally. The creatinine level is combined damage – where they may with your age, gender and require dialysis – is less than ethnicity to provide a more 15 ml/min. accurate measurement of Other blood tests you’ll have kidney function.
