METHODS: The clinical, biochemical, sonographic and histopathological findings in 186 members of six large Cypriot families with ADMCKD-1 are presented. [ncbi.nlm.nih.gov]

• Enuresis

  Secondary enuresis. Renal impairment. Renal failure with metabolic acidosis, anaemia, renal osteodystrophy and end-stage renal failure (ESRF). Once uraemia occurs - patients may have nausea, anorexia and generalised lethargy. [patient.info]

  A 6 year-old patient presents to your clinic with symptoms of polyuria, polydipsia, and nocturnal enuresis. You check a urine dip and it is negative for glucose and fasting glucose is normal. [hawaii.edu]

  Enuresis was defined as persistent bed wetting after the age of 4 years. [doi.org]

  The key symptom of MCKD is urinary concentrating defect that results in polyuria, secondary enuresis, and consistently drinking through the night. Acute gouty arthritis is another feature of this disorder. [renalandurologynews.com]

  urinary tract infections are common presenting symptoms in select symptomatic patients. [appliedradiology.com]

• Pallor

  Pallor is another characteristic finding. In contrast to other renal diseases in which the degree of anemia depends on the stage of renal insufficiency, in nephronophthisis, the severity of the anemia exceeds the degree of renal insufficiency. [emedicine.medscape.com]

  Symptoms that are common with kidney failure such as edema and pallor are rare on initial presentation. [lecturio.com]

• Failure to Thrive

  Nephronophthisis-medullary cystic disease In children, this disorder can lead to a failure to thrive, growth retardation, bone deformities, or muscle spasms caused by low calcium. Juveniles may have poor bone formation and neurologic abnormalities. [my.clevelandclinic.org]

  Common findings include a failure to thrive and weakness. Anorexia, nausea, pruritus, bone pain, and neurologic symptoms herald ESRD. Because of salt wasting, hypertension is rare, except in the infantile form of nephronophthisis. [emedicine.medscape.com]

  Unilateral or bilateral nephrectomy is performed in cases of respiratory compromise in neonates or when failure to thrive is present. Dialysis and transplantation are treatments of choice in end stage renal disease. [lecturio.com]

• Short Arm

  License: Open Access ARPKD is caused by a mutation in the PKHD1 gene on the short arm of chromosome 6. The protein encoded by the gene is expressed by renal and hepatic epithelial cells, but its function remains only partially understood. [lecturio.com]

  The genes responsible for ADPKD include PKD1 (located on the short arm of chromosome 16 and encoding polycystin 1), PKD2 (located on the long arm of chromosome 4, encoding polycystin 2), and PKD3 (location not definitively known). [hawaii.edu]

• Kidney Failure

  CONCLUSION: MUC1 mutation results in progressive chronic kidney failure with a bland urinary sediment. [ncbi.nlm.nih.gov]

  Although dialysis is a life-sustaining treatment, people with kidney failure may also be able to undergo a kidney transplant. MCKD leads to end-stage renal disease — in other words kidney failure will occur eventually. [healthline.com]

  As the disease progresses, kidney failure develops. Treatment may involve taking medicines and diet changes, limiting foods containing phosphorus and potassium. You may need dialysis and a kidney transplant. [nlm.nih.gov]

• Polyuria

  The first sign of MCKD is polyuria; later, the clinical findings relate to renal insufficiency. Originally, NPH and MCKD were considered separate entities. [ncbi.nlm.nih.gov]

  Nephronophthisis and autosomal dominant tubulointerstitial kidney disease cause inability to concentrate urine (with polydipsia and polyuria), sodium wasting, anemia, and ESRD. [merckmanuals.com]

  Symptoms typically appear at an average age of 28 years and may include polyuria (excessive production or passage of urine) and low urinary osmolality (decreased concentration) in the first morning urine. [diseaseinfosearch.org]

  Other clinical features at presentation can include abdominal pain, palpable abdominal masses, hematuria (gross or microscopic), polyuria with a urinary concentrating defect, UTI, or hernias. [hawaii.edu]

• Renal Insufficiency

  The patient in the index case presented with renal insufficiency as a child. [ncbi.nlm.nih.gov]

  Thirty-four subjects suffered from hyperuricaemia and 28 suffered from renal insufficiency. The pedigrees for families 2 and 3 identify all subjects who suffered from hyperuricaemia or renal insufficiency. [doi.org]

  Later, symptoms of renal insufficiency typically progress to include anemia, metabolic acidosis and uremia. End stage renal disease (ESRD) eventually follows. [diseaseinfosearch.org]

• Nocturnal Enuresis

  A 6 year-old patient presents to your clinic with symptoms of polyuria, polydipsia, and nocturnal enuresis. You check a urine dip and it is negative for glucose and fasting glucose is normal. [hawaii.edu]

• Uric Acid Increased

  This decreased concentrating ability probably results in increased urinary salt and water excretion, resulting in increased proximal tubular reabsorption of uric acid. [doi.org]

• Lymphocytic Infiltrate

  In case 3, tubules were ensheathed by dense acellular hyaline material. 3 In family 4, biopsy samples showed focal tubular atrophy with interstitial fibrosis and lymphocytic infiltration. [doi.org]

Treatment for MCKD MCKD is a slow, progressive disease. There is no cure. Treatment aims to manage the symptoms and decrease the risk of complications. [betterhealth.vic.gov.au]

Therefore, it may represent a treatment of choice in MCKD1 patients with ESRD. [ncbi.nlm.nih.gov]

Lifelong treatment may control the symptoms of chronic kidney disease. [nlm.nih.gov]

Outlook (Prognosis) The age at which people with ADTKD reach end-stage kidney disease varies, depending on the form of the disease. It can be as young as in the teens or in older adulthood. [mountsinai.org]
