Presentation
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]
A kidney ultrasound in this condition usually shows normal or small sized kidneys (occasionally cysts are present). [en.wikipedia.org]
Gastrointestinal
- 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]

- Suggestibility
Although earlier reports had suggested that one single gene may be responsible for this pathology, recent reports have shown that the FJN complex itself comprises a genetically heterogeneous group. [ncbi.nlm.nih.gov]

- 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]
There is no recognized gender predilection Presentation with polydipsia and polyuria, due to initial tubular injury, tends to progress to end stage renal failure, growth retardation, lethargy. [radiopaedia.org]
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 Pathologies
- 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
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. [mountsinai.org]
Treatment for MCKD may include correction of water and electrolyte imbalances, and dialysis followed by renal transplantation for end-stage renal failure. [diseaseinfosearch.org]
Prognosis
Sep 11, 2005 316 1 241 33 Status Medical Student #1 Both have "cysts" in the medulla but Medullary Cystic has a poor prognosis, and medullary sponge kidney is benign with just a predisposion to kidney stones (and less often, hematuria and UTI's). [forums.studentdoctor.net]
Prognosis for ARPKD Prognosis varies considerably. Patients who are born with oligohydramnios most often die due to pulmonary complications. [lecturio.com]
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]
Treat associated renal failure - usually haemodialysis followed by renal transplantation (the illness does not recur in the transplanted kidney). [ 1, 2 ] Prognosis Most children will develop renal failure by mean age of 13 years. [patient.info]
In addition to diagnosis, imaging studies play a pivotal role in long-term surveillance, assessing prognosis, and testing efficacy of drugs. [appliedradiology.com]
Etiology
Etiology and Pathophysiology of MCK MCK presents in two types, and both are inherited in an autosomal dominant fashion. [lecturio.com]
[…] renal calices → possibly caused by secondary hyperparathyroidism References: [3] [2] Pathology Differential diagnoses Multicystic dysplastic kidneys Definition : renal dysplasia with multiple cystic dilatation of nephrons during embryonic development Etiology [amboss.com]
We also propose that hypokalemia induced tissue proliferation may, at least in some cases, be the etiological factor for the often described association of renal tubular acidosis and cystic disease of the kidney. [bmcnephrol.biomedcentral.com]
Epidemiology
Definition / general Sporadic cystic disease characterized by bilateral cystic dilations of medullary collecting ducts; normal cortex Epidemiology 1 per 5000 births; no gender preference; not familial Associated with hemihypertrophy of body (25% of cases [pathologyoutlines.com]
Epidemiology Incidence ADPKD : ∼ 1/1,000 ; one of the most common inherited kidney diseases in humans ARPKD : ∼ 1/20,000 References: [1] [2] Epidemiological data refers to the US, unless otherwise specified. [amboss.com]
Multicystic Dysplastic Kidney (MCDK) Epidemiology of MCDK MCDK is one of the most frequent congenital kidney disorders. [lecturio.com]
[…] recessive and patients develop end-stage renal failure (ESRF) by adolescence. [ 1, 2 ] The protein products, named nephrocystins, which become abnormal in this disorder, have primarily a function in cilial structures (making it a ' ciliopathy '). [ 3 ] Epidemiology [patient.info]
Pathophysiology
Etiology and Pathophysiology of MCK MCK presents in two types, and both are inherited in an autosomal dominant fashion. [lecturio.com]
Definition Pathophysiology Classification (or lack thereof) Diseases 3. Cyst: fluid-filled sac that grows on the surface of, or within the kidney Generally arise from renal tubules 6. [slideshare.net]
Conclusion The association of cystic renal disease with hypokalemia, and the possible pathophysiological basis of the development of renal cysts in patients with severe hypokalemia, are discussed. [bmcnephrol.biomedcentral.com]
Improved understanding of pathophysiologic mechanisms has led to development and testing of novel drugs for some of these diseases. [appliedradiology.com]

These mutations alter the structure of the protein, preventing its release from kidney cells. Abnormal buildup of uromodulin may trigger the self-destruction (apoptosis) of cells in the kidneys, causing kidney disease. [ghr.nlm.nih.gov]
