obsolete autosomal recessive polycystic kidney

Autosomal Recessive Polycystic Kidney Disease (ARPKD) was previously known as "infantile PKD" or "obligate infantile PKD". This term referred to the condition's tendency to manifest in infancy, with symptoms and characteristics that were distinct from those of adult-onset polycystic kidney disease (ADPKD).

Key Features:

• Infantile presentation: ARPKD was characterized by its early onset, often presenting in the perinatal or neonatal period.
• Renal involvement: The condition primarily affected the kidneys, with cyst

Based on the provided context, here are the signs and symptoms of autosomal recessive polycystic kidney disease (ARPKD):

Common Features

• Enlarged kidneys with a "salt-and-pepper" appearance due to multiple cysts [1]
• Abdominal fullness and pain caused by enlarged kidneys taking up most of the space in the abdomen [2]
• Elevated blood pressure above the 97th percentile for age [6]

Other Possible Symptoms

• Nonspecific symptoms such as abdominal pain, hematuria (blood in urine), and urinary tract infections [10]
• Hepatosplenomegaly (enlarged liver and spleen) [6]
• Fullness in the renal area due to enlarged kidneys [6]

Complications

• Cyst hemorrhage
• Nephrolithiasis (kidney stones)
• Cyst infection
• Hematuria
• Reduced quality of life

Note: The symptoms mentioned above are based on the context provided and may not be an exhaustive list. It's essential to consult a medical professional for accurate diagnosis and treatment.

Summary

Diagnosing autosomal recessive polycystic kidney disease (ARPKD) can be challenging due to its rarity and similarity in symptoms with other conditions. However, several diagnostic tests can help confirm the diagnosis. These include:

• Imaging studies: Ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) scans can reveal cysts in the kidneys and liver.
• Genetic testing: Analysis of DNA from blood or tissue samples can identify mutations in the PKHD1 gene associated with ARPKD.
• Biochemical tests: Measuring levels of certain enzymes, such as gamma-glutamyl transferase (GGT), can help diagnose ARPKD.

Detailed Information

Here are some specific diagnostic tests used to diagnose ARPKD:

• Ultrasound: This non-invasive test uses high-frequency sound waves to create images of the kidneys and liver. It can detect cysts, which are a hallmark of ARPKD (1).
• CT scans: CT scans use X-rays and computer technology to produce detailed cross-sectional images of the body. They can help identify cysts in the kidneys and liver (2).
• MRI scans: MRI scans use magnetic fields and radio waves

Based on my analysis, it appears that you are looking for information on the drug treatment of a specific genetic disorder.

According to my search results:

• Search Result 1: Autosomal Recessive Polycystic Kidney Disease (ARPKD) is a rare genetic disorder characterized by the growth of numerous cysts in both kidneys. [1]
• Search Result 2: The primary treatment for ARPKD is supportive care, including pain management and addressing related complications such as hypertension and proteinuria. [2]
• Search Result 3: There are no specific medications approved for the treatment of ARPKD. However, some studies have investigated the potential benefits of certain drugs in managing symptoms and slowing disease progression. [3]

Some of these studies have focused on:

• Search Result 4: The use of sirolimus, an mTOR inhibitor, to reduce cyst growth and improve kidney function in patients with ARPKD. [4]
• Search Result 5: The potential benefits of everolimus, another mTOR inhibitor, in managing symptoms and slowing disease progression in patients with ARPKD. [5]

It's essential to note that these studies are limited, and more research is needed to fully understand the effectiveness of these treatments.

In summary:

• Key Point 1: Autosomal Recessive Polycystic Kidney Disease (ARPKD) is a rare genetic disorder characterized by cyst growth in both kidneys.
• Key Point 2: The primary treatment for ARPKD is supportive care, including pain management and addressing related complications.
• Key Point 3: There are no specific medications approved for the treatment of ARPKD, but some studies have investigated the potential benefits of certain drugs in managing symptoms and slowing disease progression.

Based on the provided context, it appears that you are looking for information on the differential diagnosis of autosomal recessive polycystic kidney disease (ARPKD), specifically in cases where the condition is considered obsolete.

Possible Differential Diagnoses:

• Autosomal Dominant Polycystic Kidney Disease (ADPKD): This is a common hereditary cystic kidney disease that can be distinguished from ARPKD based on family history, clinical presentation, and genetic testing. [1][2]
• Congenital Hepatic Fibrosis: This condition involves the formation of fibrotic tissue in the liver and can be associated with ARPKD. However, it is essential to consider other causes of congenital hepatic fibrosis when making a differential diagnosis. [3][4]
• Multicystic Renal Dysplasia: This is a rare congenital disorder characterized by the presence of multiple cysts in the kidneys. While it can be confused with ARPKD, multicystic renal dysplasia typically presents with a more complex and variable clinical picture. [5][6]
• Bardet-Biedl Syndrome: This is a genetic disorder that affects various organs, including the kidneys, liver, and pancreas. It can be distinguished from ARPKD based on its characteristic features, such as obesity, intellectual disability, and retinitis pigmentosa. [7][8]

Other Considerations:

• Age of the patient: The age of the patient at presentation can help narrow down the differential diagnosis. For example, if the patient is an infant or young child, congenital hepatic fibrosis or multicystic renal dysplasia may be more likely.
• Family history: A thorough family history can provide clues about the presence of other genetic disorders that may be relevant to the differential diagnosis.

It's essential to note that the differential diagnosis for ARPKD can be complex and requires a comprehensive evaluation of clinical, radiological, and genetic findings. Consultation with a specialist in nephrology or genetics is often necessary to ensure accurate diagnosis and management.
