  • What are the consequences of glomerulonephritis?

    Glomerulonephritis is referred to as a kidney disease, in which glomerular epithelium is responsible for the processes of urine formation. The glomeruli consist of modified capillaries, which resemble laces and are not intended for blood supply to the kidney, but serve to filter blood from liquids and substances in it. Glomeruli can be considered as a filtering apparatus of the kidney, which consists not only of glomeruli, but also of the Bowman-Shumlyansky capsule.

    Capsule, glomerulus and convoluted tubule system( Henle loop) is a nephron that performs the function of primary urine formation. Nephrons in the kidney are many, they fill almost all the cortical substance, and some nephrons reach the limit of cortical and cerebral matter.

    The tubules of nephrons lying in the cortex are of different lengths, some of them reach the brain substance. Also, the brain substance is represented by small kidney cups, which pass into a large kidney cup, and they in turn form a renal pelvis. It collects all the formed urine and on the ureters, departing from the renal pelvis, it goes into the bladder.

    Causes of glomerulonephritis

    Glomerulonephritis can be acute, chronic and fast-progressive. Any of these forms proceeds with the defeat of the glomerular apparatus of the kidney, however, the time of onset of visible disturbances is different in each case. Most often, both kidneys are involved in the process.

    The cause of glomerulonephritis can be both infectious and non-infectious agents. Among the infectious factors of greatest importance are streptococci, staphylococci, pneumococci. Of the staphylococci, the most dangerous is beta-hemolytic streptococcus in group A. Glomerulonephritis can also develop as a complication after rubella, herpes, hepatitis B, after vaccinations and the introduction of prophylactic sera. The harmful effect on the kidneys is alcohol. Increases the likelihood of glomerulonephritis exposure to cold, high humidity, cavitary operations, excessive physical and psycho-emotional stress.

    In most cases, glomerulonephritis arises from an imperfect immune response to irritant factors, so there is always an explanation in the definition of the disease that this is an autoimmune disease.

    Clinical manifestations of glomerulonephritis

    Among the main symptoms of glomerulonephritis are:

    • Bilateral pain in the lumbar region.
    • High temperature.
    • Headaches, blurred vision, decreased visual acuity.
    • Hearing loss.
    • Insomnia.
    • Mental and motor anxiety.
    • Changing the color of urine is a pale pink color.
    • Swelling of the face and eyelids in the morning, in severe cases, liquid can accumulate in the cavities of various organs - the heart, lungs, abdominal cavity.
    • Cardialgia and shortness of breath.
    • Increased blood pressure, but the pulse rate decreases.
    • Changes in the fundus - swelling of the nipple of the optic nerve, narrowing of the small arteries of the eye.

    Not necessarily all of the above symptoms should be present simultaneously in the patient, it depends on the form in which the disease and the degree of activity of the process. But the more significant damage to the glomerular apparatus, the greater the number of symptoms present in the clinical picture and the more likely the development of complications.

    Complications of glomerulonephritis

    With glomerulonephritis, the kidneys can not fully perform their functions, and the body gradually accumulates excess fluid, as well as metabolic products. This is primarily due to inflammation in the kidneys and the formation of scar tissue. It is a kind of barrier, dissociates healthy kidney tissue from inflammation. As a rule, scar tissue forms foci of sclerosis, which are unable to perform the basic functions of the kidneys. The more extensive the inflammation, the larger the focus of sclerosis, the less the kidney is able to filter and form urine. So, the more pronounced the symptoms and the more difficult the general condition of the patient.

    Therefore, the effects of glomerulonephritis can be expressed in sclerosis in the kidney and the development of acute heart failure, which is also called cardiac pulmonary edema. In addition, the complications can be in the form:

    • Acute renal failure;
    • Strokes;
    • Sudden acute visual impairment( transitory condition due to spasm of retinal vessels);
    • Eclampsia.

    The most dangerous for life and health are acute renal failure and eclampsia.

    Eclampsia

    Eclampsia manifests itself in the convulsive readiness of the striated, respiratory musculature and diaphragm. Eclampsia is also called angiospastic encephalopathy.

    Leading symptoms with eclampsia:

    • Severe headaches;
    • Tonic, and then clonic convulsions after a noisy sigh or loud scream;
    • Loss of consciousness;
    • Blue face and neck;
    • Swelling of the veins of the neck;
    • Dilation of pupils;
    • Blood-colored foam from the mouth( due to the bite of the tongue);
    • High blood pressure numbers, a rare pulse;
    • Noisy, wheezing.


    Without the provision of emergency medical care for eclampsia, a hemorrhagic stroke is possible. The attack lasts no more than 20-30 minutes and leads to a short-term co-morbid( inhibited) state, although occasionally the patient falls into the eclampsic coma. The main treatment for eclampsia is to ensure a strict bed rest, rest physically and emotionally. With the help of medications, vascular spasm is removed, blood pressure is normalized, and excess fluid is eliminated from the body.

    Acute renal failure

    In describing what glomerulonephritis is dangerous for, it is worth mentioning one more serious complication. As a result of processes that violate the basic renal functions - renal blood flow, glomerular filtration and the reverse absorption of certain substances, the secretion of hormones( renin and angiotensin), there is a sharp shift in the water-electrolyte and acid-base balance of the body and develops acute renal failure.

    In the initial stages of acute renal failure, a shock clinic( lowering blood pressure below 90/50 mmHg, pallor and moistening of the skin, increasing heart rate), nausea, abdominal pain and a daily diuresis decrease 3-4 times lowernorms. After a while( within 2 hours) the patient's condition worsens, urine output decreases to 300 ml per day, and in especially severe cases up to 50 ml, there are pains in the lower back, drowsiness, weakness, headaches, cramps, the tongue becomes dry, covereda thick layer of brown plaque.

    Symptoms of pulmonary edema, left ventricular failure may develop. In the future, with appropriate therapy in the conditions of intensive care, the patient leaves this state, the amount of urine released increases, the pressure increases, and gradually the general well-being improves, symptoms of poisoning of the body go away. However, clinical recovery occurs only with adequate and prolonged therapy, as a result of which it is possible to restore the efficiency of the kidneys.

    Prognosis with glomerulonephritis

    If glomerulonephritis was acute, then with proper treatment, recovery is achieved in half a dozen months. Sometimes the disease lasts up to a year and a half and the kidney function is normal. But if, at the end of this period, changes in the functioning of the kidneys persist at the physical or laboratory level, it can be said that the process has acquired a chronic course.
