[…] kidney function and eventually end-stage renal disease by the fifth or sixth decade of life. 2 Worldwide, about 12.5 million people have ADPKD, and it accounts for about 10% of cases of end-stage renal disease. 1,3,4 ADPKD has a variety of clinical presentations [mdedge.com]

A few prognostic factors for disease progression are presently available to aid in the identification of earlier supportive treatment needs. [ajpb.com]

This leads to progressive impairment of renal function. 7 Patient presentation and history The initial workup of a patient presenting with ADPKD should include a full history and physical exam. [clinicaladvisor.com]

Referral should be considered for patients presenting with cystic renal disease, or those who may be at risk of this. [newcastle-hospitals.org.uk]

Physical signs at presentation in elderly patients with ADPKD. The most common presentation was hypertension in 70.6%. [pubs.sciepub.com]

• Localized Pain

  Infected cysts cause localized pain or tenderness, fever, leukocytosis, elevated erythrocyte sedimentation rate, and high serum concentration of alkaline phosphatase 65. The rupture of a hepatic cyst can cause acute abdominal pain and ascites. [revistanefrologia.com]

• Abdominal Fullness

  However, a recent report of the HALT-PKD trials showed that symptoms relating to abdominal fullness and pain are greater in patients with more advanced disease. 13 Additionally, while a relationship between loss of kidney function and increasing healthcare [ajpb.com]

• Long Arm

  A second defect, termed ADPKD type 2 (ADPKD2), is responsible for 10-15% of ADPKD cases and is found on the long arm of chromosome 4. [emedicine.medscape.com]

• Hyperactivity

  Angiotensin I is converted to angiotensin II by ACE in distal tubules, which in turn stimulates angiotensin II receptors, causing sodium and water retention in distal tubules. 37 This may be responsible for hypertension in the initial stages; however, RAAS hyperactivity [mdedge.com]

ADPKD workup In the initial workup of an individual with ADPKD, special attention should be given to the family history, social history, and medical history as well as to the genitourinary, GI, and cardiac/vascular portions of the physical exam. [clinicaladvisor.com]

• Pyuria

  Pyuria is common even without bacterial infection; thus diagnosis of infection should be based on culture results and clinical findings (eg, dysuria, fever, flank pain) as well as urinalysis. [merckmanuals.com]

  In the past, the incidence of urinary tract infection may have been overestimated in ADPKD because of the frequent occurrence of sterile pyuria. [revistanefrologia.com]

• Abnormal Renal Function

  Mean age of rupture is lower than in the general population (39 years vs 51 years) and may not be associated with abnormal renal function or blood pressure. [patient.info]

No treatments are currently approved for ADPKD. Early supportive treatment of symptoms to slow disease progression may reduce healthcare utilization and costs by reducing disease burden. [ajpb.com]

Most patients with polycystic liver disease have no symptoms and require no treatment 62. The treatment of symptomatic disease includes the avoidance of estrogens and the use of H2 blockers or proton pump inhibitors for symptomatic relief. [revistanefrologia.com]

Treatment Treatment is symptomatic in the case of ADPKD and also includes monitoring for complications such as heart valve disease and brain aneurysms. In children with ARPKD, treatment is more urgent and intensive. [news-medical.net]

Prognosis In ARPKD, the prognosis depends on how early the cysts start to develop. Thus if a developing fetus shows kidney cysts, the disease is more severe than if the cysts first occur after birth. [news-medical.net]
