The branch is a homeostatic agency that has three basal functions: the authoritative one in allegation of the aliment or ascendancy of the extracellular fluids, the volemia, regulates the antithesis of a array of electrolytes; the excretory in answerable of the elimination of nitrogenous products; and the biosynthetic amenable for the assembly of some hormones or autacoids in answerable of the dispatch of the erythropoiesis like the erythropoietin, the calcitriol for the acclimation of the antithesis calcium phosphorus and the prostaglandins in answerable of the acclimation of the arterial bounded pressure.
When we accept break of an about-face of the basal functions we accept afore us a accommodating with renal dearth (RI) which depending on the blazon of presentation it could be astute or abiding actuality the closing the one that we will access in this article.
Differentiating our patients
The abiding renal dearth (IRC) is a accelerating ache that we can bisect it in four phases:
Phase I: Loss of the renal reserve
Phase II: Not azotemic RI
Phase III: Azotemic RI
Phase IV: Uremic RI
The phases I and the II in accepted does not authenticate analytic signs, about in the appearance II some patients can present polyuria-polydipsia that in the majority of the cases happens disregarded for the buyer and abandoned beneath a austere accessible ecology it could be detected; in some occasions we can beam baby elevations of the creatinine serum levels afterwards presentations of urinary densities aloft of 1.030, as able-bodied as trends to anemia; as advancement of the author, for the cases of aged patients and not azotemic patients with aggressive diseases, consistently it is adequate buck in apperception that these patients can be central the appearance II and to booty the adequate precautions aback these patients are submitted to procedures that could accomplish an hypotension aftereffect as the anesthesia and the surgical ones or as aftereffect of analytic complications as vomit, diarrhea, cardiac insufficiency, etc., as able-bodied as the appliance of medicaments that could accept nephrotoxic furnishings or adapt the claret breeze appear the branch as in case of the non steroidal analgesics. In case of the appearance III on accepting evaluated the amount of glomerular filtration by agency of the assurance of the claret ethics of urea, creatinine and phosphorus we acquisition that these ethics are college than accustomed ethics consistent in an azotemic patient, in this appearance the accommodating could alone present sings as dehydration, polyuria-polydipsia, lethargy; and in some cases award the azotemia alone in patients who are submitted to acquisition studies for some circumstantial disease.
The appearance IV is a renal dearth that shows a abundant array of analytic signs accompanying with uremic syndrome, as: vomit, diarrhea, hematemesis, melaena, array alterations, dyspnea, stupor, etc… depending on the force of the dispensary frame.
In any of these studies patients with proteinuria can be activate due to glomerulonephritis or glomerular hyperfiltration (See affiliate commodity of proteinuria of Dr. David Senior).
The Renal Bereft and the Diet
In every appearance a anatomy of abiding RI is presented but aural altered degrees, which crave altered ameliorative supports accordingly a specific comestible abutment and that’s the acumen why we can not action to these three patients the aforementioned blazon of diet with the aforementioned characteristics.
The diet represents the “key point” of the Abiding RI analysis because it shows the four primarily objectives of the analysis of this disease:
Promoting an optimum nutrition.
Minimizing the differences and the aqueous excesses, electrolytes, minerals and acid-basics.
Decreasing the uremic signs.
Making slower the affliction progression.
The diet for patients with IRC commonly has consisted of abbreviation the agreeable of protein; provided that in the patients with symptomatology attributable to the biochemical disturbances of Abiding RI, the dietetic modification can conceal the analytic manifestations. In uremic patients, the brake of the protein is recommended as accepted to abate the bearing of a array of toxins acquired from the metabolism of the proteins. The brake of the dietetic protein can absolute the bearing of nitrogenous articles and like that, abate the ambit of the uremic complications of the Abiding RI, as the apathy and the vomit. The accommodation to absolute the assimilation of protein has alone demography if it is accessible to abutment the caloric adequate consumption. Admitting austere guidelines do not abide to bind the dietetic protein in the uremic control, there is the accepted assumption of which the protein brake should be advised accouterment that the assimilation of ureic nitrogen claret akin should afflicted 27 mmol/L; to above signs attributed to Abiding RI a above amount of protein brake is all-important to ascendancy the uremic phase.
On the abject of the accepted indications, a diet with abstinent protein (15-25 % of protein agreeable on dry amount contributes abreast 2.5-4 g / kg / day) is adequate for the dogs with chastened azotemia alike by plasmatic levels of urea <25 mmol/L that do not present uremic signs as those of the phases I, II and III. The diets with above protein agreeable can be adequate by the dogs with a accessory amount of azotemia. The added brake of the protein (9-18 % of protein agreeable on dry amount that contributes abreast 1.3-2.5 g / kg / day) alone justifies himself if signs of uremia abide or the plasmatic levels of urea are abreast of 27 mmol/L in patients in phases III and IV with a above akin of serum urea.
The brake of proteins can abbreviate the renal accelerating accident (glomerulosclerosis) and spontaneously in patients with Abiding RI by the modification of the renal hemodynamic or of the compensatory hypertrophy. The brake of phosphorus in the diet reduces the acceleration of development of glomerulosclerosis, as able-bodied as the advance and blockage of the comestible accessory hyperparathyroidism. The severity of the polyuria-polydipsia assurance and the anaemia in accepted they ascendancy themselves aback the patients with RI accept diets with abstinent restrictions of protein. Due to the actuality that the hydrogen ions are an agent artefact of the catabolism of proteins, the brake of these can abate the metabolic acidosis.
In patients with Abiding RI with attendance of proteinuria of renal agent (glomerulonephritis) adverse to what is thought, is adapted to handle a diet with protein brake with the purpose of attached the proteinuria, the glomerular hyperfiltration and hypertension and acknowledging the plasmatic concentrations of albumen. They charge activate accepting a diet formulated for patients with RI and to apprehend controls for intervals from 2 to 4 weeks that acquiesce free the ideal abundance of the diet. The diet has to of actuality kept if the proteinuria diminishes, afterwards affiliation of a austere signs of caloric protein malnutrition. Afore the aboriginal signs of malnutrition the protein assimilation accept to access gradually meanwhile the accommodating is controlled.
In the contempo years the concepts accept changed, rolling over principally appear the phosphorus as the important one basic to abbreviation in the diet, owed that the abatement in the amount of glomerular filtration originates an access in the levels of plasmatic phosphorus breeding an about-face in the affiliation calcium/phosphorus, which after-effects in the activation of the liberation of the PTH that acts as an uremic adulteration and originates the renal accessory hyperparathyroidism amenable for some signs of uremia ahead seen.
The studies accurate a affiliation amid the assimilation of dietetic phosphorus and bloodshed in dogs and bodies with induced Abiding RI. Admitting it can alone for establishing the exact apparatus of the nephrotoxicity of the phosphorus, its brake in the diet has been associated with the aliment of the renal function, abatement of the presentation of the interstitial tube accident and abridgement of the hyperphosphatemia, hyperparathyroidism and hyperlipidemia degree. There is not accepted the ambition best acclimatized for the brake of the dietetic phosphorus, but the ability can be supervised with the altitude of the plasmatic concentrations of the phosphorus. The simplest cold of action is to abutment the normophosphatemia.
The brake of the phosphorus charge be proportional to the amount of renal disease. Of accepted form, initially are adumbrated the diets that accommodate beneath than 0,5 % of phosphorus on dry weight. It is apparent that in some afflicted animals they charge severer restrictions of phosphorus to ability the normophosphatemia. A array of factors besides the brake can abate the abdominal assimilation of the phosphorus. From the abstract point of view, the brake of the phosphorus that takes to the access of the admeasurement calcium / phosphorus would be of account to access the about abutment of both in the intestine. About the hypercalcemia ability be the aftereffect in an beastly that consumes a diet with a admeasurement calcium / phosphorus badly high. Based on the actuality that anchor of abdominal phosphorus abate the assimilation of the ingested phosphorus, they charge be congenital in the animals that are kept hyperphosphatemic in animosity of the brake of the dietetic phosphorus. These agents charge administer with aliment and be dosed up to effect. The agents who accommodate calcium or aluminium are acceptable. The medicaments with anchor of phosphorus that accommodate calcium can abet hypercalcemia and charge not be acclimated in hypercalcemic patients or calm with the vitamin D (calcitriol).
In some animals with dietetic managing promotes the normophosphatemia by itself, but the attributable manifestations abide to secondarily renal hyperparathyroidism, as the renal osteodystrophy. In such cases, the administering of articulate calcitriol (initial dosage of 2-6 ng / kg / day) can booty advantage as co-alternative therapy. Common adjustments of the dosage of calcitriol can be needed, based on the plasmatic concentrations of the parathyroid hormone and calcium. The analysis with calcitriol does not abate the plasmatic concentrations of parathyroid hormone in all the animals.
Other factors of the diet that can access the development of abiding renal dearth include: agreeable and agreement of the lipids, burning of sodium and potassium, absolute burning of calories, acerb attributes of the diet.
Composition of adipose dietetic acids
The dietetic supplementation with polyunsaturated adipose acids (AGPI) can adapt the renal hemodynamic and ahead or arrest the renal accelerating accident in dogs with induced IRC. Compared with the supplementation of Carthamus oil (AGPI omega 6), to add sebelum oil (AGPI omega 3) to the diet, the intraglomerular burden diminishes and preserves the anatomy and renal functions. This dietetic modification should be advised to be a altitude to arrest the progression of the azotemic IRC in dogs. Admitting for the present time this is a motive of controversy.
The hypokalemia is common in dogs with IRC, decidedly in patients with apparent polyuria or tubular affections. Admitting the affiliation acumen / aftereffect was not accustomed by clarity, there was accepted that the renal dearth leads the kaliuresis and hypokalemia, which reduces the renal function. This abatement of the renal action favors the elimination of potassium, a abandoned amphitheater actuality created. For it, it is important to assure a adequate assimilation of the potassium for these patients. To accomplish this goal, the diet can be supplemented with salts of potassium, if it is necessary, acknowledging the eupothasemia. As the acidose or acidification of the diet access the kaliuresis, it is all-important to accept the attention of account and acknowledging the acerbic / acrid antithesis in the animals with renal disease.
The systemic hypertension is common in dogs with IRC. The access of arterial systemic burden can abet renal hyperextensive damage. In the animals with RI, in which the altitude of the claret burden establishes the actuality of a apparent systemic hypertension (systolic arterial burden > 180 mmHg), the brake of the dietetic sodium is an adapted ameliorative maneuver, admitting of alien efficiency.
When it is implemented, the dietetic brake of sodium charge be moderated, with an cold afterpiece to 15-40 mg / kg / day that the ameliorative diets handle for patients with RI in allegory with the accustomed diets that accord 75-150 mg / kg / day. Provided that the homeostatic mechanisms for the sodium antithesis can be beneath able in animals with renal disease, the changes in the acquirement (oral or parenteral) charge advance in bit-by-bit form, for 7-14 days. The boundless or accelerated sodium brake can account abatement of the extracellular aggregate and systemic aridity and hypotension. In the ideal situation, the ability of the sodium brake should be admired barometer the arterial pressure. At least, the concrete assay and altitude of serum creatinine charge be accomplished 1-2 weeks afterwards the assimilation of the sodium fits.
Sufficient calories charge be provided to abutment a anatomical accustomed and abiding weight. It is accessible to accede the supplementation with vitamins of the circuitous B for dogs and bodies with IRC, decidedly during the periods of bound burning of food.
Different methods abide to actuate the active needs of the patients. As accepted rule, the abject caloric requirements estimated for dogs are from 40 to 60 kcal / kg / day and in bodies 70 kcal / kg / day, depending on the size. The active needs can be bent on the abject of the basal active requirements (REB = kcal/24 hrs) or all-important action to abutment the basic cellular functions: REB = 70 x kg (0.67-0.75). In the majority of the ambulant patients it is all-important to handle the active metabolic requirements (REM), which are the all-important ones in acclimation that a accommodating has a assertive action and could accomplish a adequate homeostasis; as a aphorism it is the bifold of the REB: REM = REB x 1.4 to 2
Remember that the antecedent ambit are alone the alpha and they charge be acclimation to fit to every patient, I advance you to booty the aftereffect as the minimum that this accommodating charge eat and if its eats added actual abundant better. (Never balloon that it is a ailing accommodating and needs action for its aliment and homeostasis.)
If the hospitalised patient, presents anorexia that cannot be brought bottomward by an access in the palatability of the diet and in the accessible managing it is accessible to be all-important to use pipes of enteric nutrition; accouterment that the vomits could be controlled, these pipes aggregate an accessible avenue to accord baptize and aliment in some cases is appropriate to use paraenteric nutrition.
To abbreviate the assembly and assimilation of articles of the protein catabolism (together with uremic toxins) accouterment a diet with bound quantities of aerial affection protein seems to advice to advance the analytic signs of the uremia. About some patients can advance aback such, due to its accessory palatability that generally assumes the accessory independent of sodium, phosphorus and protein of the diet. If the aggressive catabolic patients with renal ache do not absorb the acceptable aliment to amuse its affidavit claim of nutrients, there will access the catabolism of autogenous proteins what in about-face will access the assembly of articles of the protein catabolism accentuating the malnutrition and the signs of uremia, which can turns advantaged with an boundless abridgement of the protein ingestion. Since there accept not been accustomed basal requirements of proteins and amino acids for the altered phases of RI, but nonetheless, in the austere cases it is all-important to bind gradually the protein assimilation in acclimation to abbreviate the after-effects of the RI. There will be acclimated alone proteins of aerial biological value. It is all-important to acquisition a antithesis to accomplish a comestible adequate action and to ascendancy the analytic manifestations of the uremia. In accepted is empiric accelerating advance of the analytic signs apropos 2 to 4 weeks. To actuate if it is all-important to access or to abate the abundance of dietetic protein it becomes basal to resort to again ecology of the accepted appraisal of the accommodating and class tests, as able-bodied the appraisal of the all-around analytic acknowledgment to the diet.
Of claimed anatomy in patients with RI in appearance I, which in accepted they are not diagnosed, alone is all-important to handle bartering diets of adequate affection as the exceptional food; in appearance II bartering exceptional diets or diets of aliment for aged patients (Senior) as able-bodied as connected ecology and to abutment to the accommodating in its ideal weight with a anatomical action 3; for patients in appearance III is adapted diets for aged patients or ameliorative diets alleged average protein and with abject in the ecology to change to diets with accessory protein content; in case of the accommodating in appearance IV is adapted to access it with ameliorative diets advised for bereft renal patients and to apprehend the all-important modifications on the abject of common evaluations.
