Myeloma – an overview

that are normally found in the bone marrow. Plasma

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,

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

      The excessive amount of

      damage the kidneys. When they

      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

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.

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.
