Diabetes Insipidus is a medical condition characterized by excessively dilute urine production. The failure of the posterior pituitary in its excretory roles results in the infection of Nephrogenic Diabetes Insipidus. The importance of care and diagnosis in the management of this diabetic condition cannot be overstated. The standard form of diagnosis is the well-known water deprivation test ( Sands et.al).
Over the last ten years, human perception of NDI has evolved and improved dramatically. Understanding this infection relies heavily on cellular pathways experience of water re-absorption. There are essential cellular components whose response to Vasopressin lowers the osmotic gradient of water molecules hence causing the causative agents of NDI. Vasopressin plays a key role in the process of regulating collecting duct permeability in the kidney. The flow and control of the water and urine content form the Urine –concentrating mechanism. One of the important chemical substances in the re-absorption process is NaCl. The concentration gradient between this chemical substance and urea stimulates the process of re-absorption from the collecting duct into the inner interstitium ( Sands et.al). The congenital causes of NDI cannot be avoided in all dialysis and genetic diagnosis of this infection. Mutation in the V2 receptor is responsible for the X-link recessive inheritance mode.
Generation of the hypertonic medulla is a property which is associated with NDI. There are several congenital disorders which affect the generation this medulla. The process is performed under electrolyte imbalances, polydipsia and dehydration in the cystinosis mechanisms. The chemistry of urea transporters is slowly permeable across the lipid layers. Urea permeability is more than zero, and it will diffuse to achieve a resilient stability and steady state with time. Urea transporter –B is the transporter which is erythrocytic ( Sands et.al)
The role of a practitioner in the care of patients with this particular disease is vital. For adults who are victims of this disease, close medical care determines the number of years they live with it. The practitioners ensure that the patient's diet and the provisions of exogenous vasopressin are technically and keenly controlled and regulated ( Sands et.al). The experts are specialists in various ways of handling the infections, for example, Lithium Therapy.
Lithium Therapy is the most common cause of NDI. It is responsible for the complications in approximately 55% of NDI patients. It causes the infection through reduction of the protein abundances of UT-B, UT-A1 and AQP2. It also causes marked down-regulation of AQP2 protein, water restriction and vasopressin stimulation defects. Other causes include low protein diets, hypokalemia, hypercalcemia and ureteral obstruction release. Another natural cause is ageing. Normal ageing is a factor which reduces maximal urine concentration in both human beings and rats. The phenomenon of urine –concentration is attributed to both partial nephrogenic and central diabetes insipidus.
Finally, it is proven that NDI is a rare inflectional disorder which affects the human kidney. It can result from genetic disorders and abnormalities or in the loopholes of generating hypertonic medulla. For adults, the disorder is directly linked to their increasing ages. The treatment processes and systems need to embark majorly on the renal and bladder organs of the patient and provide suitable and quality testing and counselling.
