Familial Juvenile Hyperuricemic Nephropathy Type 1

FJHN


Presentation

  • There is marked interfamilial and intrafamilial variability that was also seen in the present family. Hyperuricemia is present in 83.3% of the cases and gout in 45% of mutation - positive cases.[indianjnephrol.org]
  • Genetic abnormalities are carefully presented within the appropriate physiologic context so that readers will understand not only which genes are linked to which diseases but also which pathways lead from a genetic “disturbance” to the systemic appearance[books.google.com]
  • Case presentation Case report The proband is an affected female who was first evaluated at the age of 24, when she presented with a gout attack and hyperuricemia. At age 27 she was told having renal failure.[link.springer.com]
  • Conclusions: The present study reported a novel mutation in exon 9 of UMOD in the Chinese Han population, within the GPI anchor signal segment of uromodulin.[karger.com]
Severe Pain
  • About two o'clock in the morning he is awakened by a severe pain in the great toe; more rarely in the heel, ankle, or instep. This pain is like that of a dislocation, and yet the parts feel as if cold water were poured over them.[books.google.com]

Chills
  • Then follow chills and shivers, and a little fever. The pain, which was at first moderate, becomes more intense. With its intensity the chills and shivers increase. ‎[books.google.com]

Shivering
  • Then follow chills and shivers, and a little fever. The pain, which was at first moderate, becomes more intense. With its intensity the chills and shivers increase. ‎[books.google.com]
Kidney Failure
  • 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.[medlineplus.gov]

  • They are not the same thing as polycystic kidney disease, which is a progressive disease that can lead to kidney failure. Simple kidney cysts most often do not cause harm.[webmd.com]
  • Dominant mutations in the REN gene, which encodes renin, have recently been described in families with hyperuricemia, anemia, progressive kidney failure, and progressive interstitial fibrosis. [11] These patients may also be considered to fall under the[emedicine.medscape.com]
Renal Impairment
  • Mild renal impairment is usually asymptomatic in the initial phases and, as such, this mutation is likely to be underdiagnosed.[bjd-abcd.com]
  • Renal impairment usually appears between 15 and 40 years of age, leading to end-stage renal disease (ESRD) within 10 to 20 years [ 1 ].[link.springer.com]

Workup

  • The ability to identify a disease-causing mutation also allows diagnostic workup for living-related transplantation to be more precise.[oapublishinglondon.com]

Treatment

  • Take advantage of expanded coverage of small molecule treatment, biologics, biomarkers, epigenetics, biosimilars, and cell-based therapies.[books.google.com]
  • However, there is no correlation between the presence of hyperuricemia or gout and development of ESRD. [9] Definitive treatment is renal transplantation.[indianjnephrol.org]
  • Simple Kidney Cyst Treatment If your cyst does not cause symptoms or complications, you do not need treatment. Your doctor may simply watch your cysts to make sure they don't cause any problems.[webmd.com]
  • ADSL no effective treatment has been identified. AICAR-TF/IMP-CH no effective treatment has been identified. Adenylate kinase treatment is supportive care of the hemolytic anemia resulting in this condition with transfusion.[clinicaladvisor.com]

Etiology

  • They are organised into groups, and further divided into clinical, etiological or histopathological sub-types.[orpha.net]

Pathophysiology

  • Moreover, the recent development of a recombinant form of urate oxidase transforming uric acid into allantoin (Rasburicase) has caused new interest in the pathophysiology of hyperuricemia and the potential applications of this new drug.[books.google.com]

  • Advancements in our understanding of the human genome, and specifically the different variants of MODY and their underlying pathophysiology, can lead to greater recognition and management of conditions such as type 5 monogenic diabetes type or RCAD.[bjd-abcd.com]

Prevention

  • It has been suggested that one of THP major role is of an urinary anti-adherence factor preventing type 1 fimbriated E coli from binding to the urothelial receptors [ 13 ].[link.springer.com]

  • With early diagnosis and treatment, clinical manifestations of gout can be prevented or delayed; however, there is only anecdotal evidence that allopurinol may slow the rate of progression to ESRD[ 41 ]. References[uscapknowledgehub.org]
