Five common complications of Multiple Myeloma

Multiple Myeloma is a cancer of plasma cells, also known as activated B cells, capable of producing a monoclonal line of globulins. This cancer is frequently seen in populations in risk of radioactivity, for example in sites of nuclear explosions. MM is seen in old people, reaching its peak at 70. Males are slightly more hit than females.

 

Five common complications:

Bone lesions: Bones are frequently the first site of lesion in the body. Cancerous cells can either line up inside the bone tissue, causing fragility and fractures, or produce cytokines that activate the Osteoclasts. Osteoclasts are cells that cause bone reabsorbtion, in order to keep the calcium homeostasis. In normal ground, Osteoclasts have their counterpart, the Osteoblast, that build bone tissue. If Osteoclasts work lot more than Osteoblasts, the bones become faulty, risking the fractures even in no trauma at all.

Recurrent Infections: Multiple Myeloma can cause severe infections, because of the way the immunity functions. Normally, the antibodies have polyclonal antigen binding sites, being able to fight a very wide range of risky agents. In MM, only one clone of antibodies is produced, and during the time, the other clones already produced start to fall in number. Thus the infections start, and if not controlled can lead to death.

Chronic Kidney Failure: It is a very frequent complication in patients with MM. CKF has a number of factors, like:

-           Hypercalcaemia from bone reabsorption

-           Amyloid deposits

-           Hyperuricemia

-           Recurrent infections

-           Cancer cells infiltrating the kidneys

Anemia: Patients with MM have frequently a Normocytic and Normochromic anemia. This means that the anemia is caused by a reduced number of blood cells. The factors that can lead to this type of anemia are:

-           Bone marrow infiltration by the cancerous cells

-           Cytokines produced by MM cells, interfere with the blood production

 

Neurological signs: Rarely seen, this symptoms can be: Lethargy, Confusion, Coma. High calcium in blood can be a causal factor.

New Drug List, and their Side Effects

1. Glimepiride (Amaryl) Glimepiride is an anti-diabetic drug, from the class of Sulfonylureas. It stimulates the release of insulin from the pancreas and makes the insulin receptors more sensible. This helps the lowering of blood glucose levels. It’s main side effects are: Gastro-intestinal disturbance, rarely thrombocytopenia (low platelets), leukopenia (low white cells), hemolytic anemia, occasionally allergic … Continue reading

Weekly Update Nr.1: Carotid Stenosis, Malaria, ADHD guidelines

1. The management of Asymptomatic Carotid Stenosis. The diagnosis of ACS is often casual. It happens when the physician is using ultrasound or other imaging to study blood vessels near the carotid region, or when studying the coronaries. The big debate is between two types of therapy, the Medical and the Surgical ones. Two studies are … Continue reading

Heart failure shouldn’t be your failure!

First of all, this will not be an easy topic. And it surely will be too far from funny.
Well, people die. Despite of legends, none has lived forever. The only two sure things in the world are Death and Taxes. For the fact that this website is mainly about medicine and health conditions, I’m not talking about Taxes!
But, what are the most frequent causes of death?
More than 30 % of deaths are caused only by cardiovascular problems. It means that there comes a time in life, in which the heart or the blood vessels give up! No more blood circulation, no more living. There are also a lot of other organ disorders that can make the heart stop. Then we have to mention other death causes, like Cancer, Infections, Trauma and many many others. Continue reading

Symptoms and treatment of Iron Deficiency Anemia

Iron Deficiency Anemia is called the blood disease in which the total number of red blood cells is diminished because of a Lower-than-normal quantity of Iron in the body. This condition is also called: -Sideropenic Anemia (from ancient greek: Sideros=iron, Paenia=less, An=absent, Haemia=blood) -Sideropenic Microcytic Anemia (from ancient greek: Micro=small, Cytic=cellular) -It is also spelled … Continue reading

Understanding Achalasia, the “impossible-eating” disorder!
