Renal Parenchymal Disease

Renal parenchymal disease is the most common cause of secondary hypertension. It is a group of different renal disorders which may include diabetic nephropathy, glomerulonephritis, interstitial renal parenchymal diseases, and polycystic kidney diseases.[rx] More than half of the patients with renal parenchymal diseases are found to have hypertension and the incidence of hypertension increases with the worsening of renal parenchymal disorders.[rx] Development of hypertension has a negative effect on renal parenchymal disease and it accelerates the worsening of renal function and leads to end-stage renal diseases.[rx]

Renal parenchymal diseases lead to impaired renal function that results in intravascular volume expansion. While an inappropriate activation of the renin-angiotensin-aldosterone and sympathetic system is the other mechanism responsible for hypertension in renal parenchymal diseases.[rx] Hypertension, on the other hand, leads to the worsening of the renal parenchymal disease and increases its progression to end-stage renal disease. The blood pressure in patients with advanced renal parenchymal disease is dependent on intravascular volume, that’s why fluid balance plays an essential role in controlling blood pressure in chronic kidney disease.

In endocrine disorders, different hormones are responsible for hypertension. In primary aldosteronism, higher levels of aldosterone result in volume expansion (by salt retention), while cortisol plays a similar role in Cushing`s syndrome.[rx][rx] Elevated serum levels of adrenaline and noradrenaline result in higher cardiac output as well as increased systemic vascular resistance, resulting in hypertension,  in patients with pheochromocytoma.[rx] Increased systemic vascular resistance is the primary mechanism of hypertension in vascular disorders, while secondary hyperaldosteronism plays a major role in the development of hypertension in renal artery stenosis.[rx]

Types of Renal Parenchymal Disease

Renal parenchymal disease (RPD) is classified into glomerular, tubular, interstitial, and vascular disease. These various diseases may be congenital (hereditary) or acquired.

There are two primary types of renal parenchymal disease, categorized based on the root cause of the condition.

1. Primary Renal Parenchymal Disease: This category includes conditions that originate within the kidneys themselves. Diseases like polycystic kidney disease, glomerulonephritis, or kidney stones fall under this category.
2. Secondary Renal Parenchymal Disease: These diseases occur as a result of another systemic condition or disease, such as diabetes or high blood pressure, which over time can damage the kidneys.

Further Classified

Let’s dive into the top types of renal parenchymal disease and what they mean in plain English.

1. Chronic Kidney Disease (CKD)

When kidneys are damaged for a long period (typically months or years), it’s called Chronic Kidney Disease or CKD. This means the kidneys can’t filter blood as well as they should, which leads to waste buildup in the body. It’s like when a garbage disposal system breaks down and trash starts piling up. Some causes of CKD include high blood pressure, diabetes, and recurrent kidney infections.

2. Kidney Stones

Think of kidney stones as small, hard pebbles that form in the kidneys when certain substances in the urine become too concentrated. Just like how crystals form when you leave salt water to dry, these ‘stones’ can block the urine flow and cause severe pain, much like a traffic jam in the kidneys.

3. Polycystic Kidney Disease (PKD)

Polycystic Kidney Disease is a genetic condition where multiple cysts (fluid-filled sacs) grow in the kidneys. These cysts take up space and gradually replace much of the kidneys, reducing their function over time. It’s like having a garden where weeds keep cropping up and suffocate the plants.

4. Glomerulonephritis

Glomerulonephritis affects tiny kidney filters called glomeruli. When these get inflamed or damaged, they can’t filter the blood properly, causing waste and excess fluid to build up in the body. It’s like when a sieve gets holes in it and can’t sift flour effectively.

5. Diabetic Nephropathy

Diabetic Nephropathy is a serious complication of diabetes, where high sugar levels damage the kidneys over time. It’s like when you pour too much sugar into a cup of tea, and it becomes undrinkable.

6. Hypertensive Nephrosclerosis

Hypertensive Nephrosclerosis is a type of kidney damage that results from long-standing, uncontrolled high blood pressure. It’s as if the kidneys are being squeezed tightly and over time, they can’t work properly.

7. Pyelonephritis

Pyelonephritis is a type of kidney infection often resulting from a urinary tract infection that has traveled up to the kidneys. It’s like when an invader manages to get past your home’s defenses and causes chaos.

Understanding renal parenchymal disease is the first step to effective management and treatment. Remember, your kidneys are essential workers in the body, keeping things clean and running smoothly. Take care of them as best you can, and they’ll keep working hard for you.

Causes

The Top Causes of Renal Parenchymal Disease:

1. High Blood Pressure: This is a primary cause. It damages the kidney’s small blood vessels, impacting their ability to filter waste from your blood effectively.
2. Diabetes: High sugar levels can overwork the kidneys, leading to damage over time. Both types 1 and 2 diabetes can cause this.
3. Polycystic Kidney Disease: A genetic condition causing numerous cysts to grow in the kidneys, gradually impairing kidney function.
4. Glomerulonephritis: Inflammation of the kidney’s tiny filtering units can cause renal parenchymal disease. It can follow a strep infection or may have other causes.
5. Interstitial Nephritis: Inflammation of spaces between the tubules in your kidneys. Often caused by medications, infections, or autoimmune disorders.
6. Kidney Stones: These can cause damage if they block the urinary tract, causing pressure and potential injury to the kidney tissue.
7. Urinary Tract Obstructions: These can cause kidney damage due to back pressure.
8. Vesicoureteral Reflux: A condition where urine flows back into the kidneys from the bladder, causing potential damage.

Symptoms

Let’s explore the top symptoms you should be aware of.

1. Fatigue: If you find yourself feeling unusually tired or drained, it might not just be due to a busy day. Your kidneys help produce a hormone called erythropoietin, which triggers the creation of red blood cells. In renal parenchymal disease, kidney function decreases, causing less hormone production and leading to fatigue.
2. Swollen Ankles, Feet, or Hands: Kidneys play a major role in removing extra fluid from your body. When they’re not working properly, this fluid can build up, causing swelling, usually in the lower parts of the body.
3. Shortness of Breath: When your kidneys can’t remove excess fluid effectively, it can accumulate in your lungs, making it difficult to breathe.
4. Back Pain: Kidney issues often cause discomfort or pain in the lower back, roughly where your kidneys are located. It can be a dull ache or a sharp pain, depending on the condition’s severity.
5. High Blood Pressure: Kidneys help regulate blood pressure. When they’re damaged, blood pressure can rise, potentially leading to additional kidney damage in a vicious cycle.
6. Changes in Urination: Notice any changes in color, frequency, or the amount of urine? Dark, foamy urine or frequent nighttime trips to the bathroom might signal a kidney problem.
7. Blood in Urine: Healthy kidneys filter waste from the blood, but not the blood cells. If blood appears in your urine, it could be a sign of renal parenchymal disease.
8. Loss of Appetite: With kidney disease, toxins build up in the body, leading to a loss of appetite. You might find food less appealing, or you may experience a metallic taste.
9. Nausea and Vomiting: The accumulated toxins in the body can also cause feelings of nausea and sometimes even lead to vomiting.
10. Muscle Cramps: Kidneys help maintain electrolyte balance. If they’re damaged, imbalances can cause muscle cramping.
11. Itchy Skin: Kidneys remove waste products from the bloodstream. When they’re not functioning properly, these wastes can accumulate, causing itchy skin.
12. Trouble Sleeping: When kidneys don’t properly filter toxins from the blood, it can cause sleep disturbances.
13. Persistent Puffiness Around Your Eyes: Protein in the urine, a common sign of kidney damage, often causes puffy eyes.
14. Cognitive Issues: Brain fog, trouble with concentration, or memory issues might not immediately make you think of kidney disease, but they’re potential signs.
15. Unintentional Weight Loss or Gain: Changes in appetite or an unexplained weight loss or gain can be linked to kidney problems.
16. Cold Sensitivity: If you’re feeling unusually cold, even in a warm environment, it may be a symptom of renal parenchymal disease.
17. Frequent Urinary Tract Infections: These infections can be both a symptom and a cause of renal parenchymal disease.
18. Headaches: Frequent, severe headaches could be a symptom of high blood pressure, often associated with kidney disease.
19. Pale Skin: Decreased red blood cell production can lead to anemia, causing your skin to appear paler than usual.
20. Decreased Sex Drive: A general feeling of illness, along with hormonal changes, can result in a decreased libido.

Diagnosis

Medical History 

Obtaining a complete history and performing a good physical exam is very important when trying to find the underlying cause of secondary hypertension. Development of hypertension in extremes of age accelerated end-organ dysfunction due to hypertension, resistant hypertension, and sudden rise in blood pressure in hypertensive individuals, who are stable on drug therapy, are classical features of secondary hypertension.[rx][rx][rx] The following history and physical exam findings point towards a specific cause of secondary hypertension.

• Snoring, obesity, and daytime sleepiness could be indicative of obstructive sleep apnea.[rx]
• History of renal insufficiency, atherosclerotic cardiovascular disease, and edema may warrant further evaluation of chronic kidney disease (renal parenchymal disease).[rx]
• History of recurrent urinary tract infections, kidney stones, acute/chronic abdominal/flank pain, hematuria, and progressive renal failure may point towards autosomal dominant polycystic kidney disease (renal parenchymal disease).[rx]
• Worsening renal function with angiotensin-converting enzyme inhibitors (ACEi) and a systolic/ diastolic abdominal bruit point towards the reno-vascular disease.[rx]
• Episodic hypertension, headache, and palpitation, associated with acute stress, in a perioperative setting, could be the signs of pheochromocytoma or paragangliomas.[rx]
• Decreased or delayed femoral pulses, radio femoral delay, and differences in the blood pressure in the arms are seen in the coarctation of the aorta and vasculitic causes of secondary hypertension.[rx]
• Weight gain, fatigue, weakness, hirsutism, amenorrhea, moon facies, dorsal hump, purple striae, and truncal obesity are present in Cushing syndrome/disease.[rx]
• Fatigue, weight loss, hair loss, diastolic hypertension, and muscle weakness are seen in hypothyroidism.
• Heat intolerance, weight loss, palpitations, systolic hypertension, exophthalmos, tremor, and tachycardia will occur in hyperthyroidism.
• Kidney stones, osteoporosis, depression, lethargy, and muscle weakness are present in hyperparathyroidism.[rx]
• Headaches, fatigue, visual problems, enlargement of the hands, feet, and tongue are features of acromegaly.
• Heartburn, Raynaud phenomenon, and nail pitting on the exam may be suggestive of scleroderma.

However, a comprehensive understanding of the diagnosis and tests involved can help in managing the condition better guide to understanding the top 30 diagnoses and tests for renal parenchymal disease.

1. Physical Examination: This involves questioning the patient about any symptoms experienced, previous illnesses, family history of kidney disease, and lifestyle habits. Physical examination often checks for swelling in the legs, hands, or face.

2. Blood Tests:

• Complete Blood Count (CBC): CBC helps in checking for anemia (low red blood cell count), a common symptom in kidney diseases.
• Blood Urea Nitrogen (BUN) and Creatinine: These tests measure waste products in your blood, which increases if the kidneys aren’t functioning properly.
• Estimated Glomerular Filtration Rate (eGFR): A test calculated using creatinine levels, age, sex, and race to determine kidney function.

3. Urinalysis: This test checks for protein, blood, or other substances in the urine which might indicate kidney damage.

4. Urine Protein to Creatinine Ratio: Used to estimate the amount of protein passed in the urine in a day, indicating kidney damage when high.

5. Imaging Tests:

• Ultrasound: An ultrasound uses sound waves to generate images of the kidneys, showing size, shape, and any abnormalities.
• Computerized Tomography (CT) Scan: A more detailed image of the kidneys can be achieved using a CT scan, identifying any abnormalities or obstructions.
• Magnetic Resonance Imaging (MRI): MRI provides a detailed image of the kidneys and urinary tract.
