Newborns can acquire significant coagulation factor deficiencies due to placental transfer of maternal antiphospholipid antibodies, including the lupus anticoagulant and anticardiolipin antibody. 2. These neonates can present with significant thrombosis, including purpura fulminans. Ill. Specific clinical conditions a venous thromboembolic disorders 1. General considerations a. Most venous thrombosis occur secondary to centtal venous catheters. Spontaneous (i.E., noncatheter-related) venous thrombosis can occur in renal veins, adrenal veins, inferior vena cava, portal vein, hepatic veins, and the venous system of the brain. Hematologic disorders i 549 b.

Certain solid dosage forms should not be crushed because crushing would alter release characteristics. 40 for example, controlled-release, extended-release, and sustained-release preparations should not be crushed, nor should sublingual dosage forms. Enteric-coated dosage forms generally are designed to protect acid-labile medications from stomach acid. When these dosage forms reach the small bowel with its higher ph, the drug is released into an environment in which it is more stable. Alternatively, enteric-coated dosage forms protect the stomach from medications that could cause irritation. Thus, crushing the enteric coating defeats the purpose of the dosage form and could lead to decreased efficacy or increased adverse events. Medications available commercially as compressed tablets can be crushed for administration through tubes. After crushing, the fine powder should be mixed with 10 to 30 ml of fluid (usually warm water) for administration. A powdered dosage form inside a hard-gelatin capsule can be poured out and mixed with water for administration through tubes. Soft-gelatin capsules can be dissolved in warm water. Some enteric-coated and delayedrelease microencapsulated products can be opened and individually coated particles administered through the tube without crushing if the tube has a large enough diameter. If a liquid dosage form of a medication exists, it would seem rational to use this for administration through a feeding tube. This may decrease potential for tube clogging but may in some instances decrease tolerability of medication administration. Sorbitol is an excipient found in many liquid medications in amounts sufficient to cause diarrhea. If diarrhea secondary to sorbitol is suspected, contact with the manufacturer to ascertain sorbitol content may be necessary. Another potential problem with administration of liquid medications through feeding tubes is high osmolality of some products. Dilution of hypertonic medications with 30 to 60 ml of water or administration of smaller dosages more frequently may help prevent diarrhea. Although administration of iv medications through feeding tubes may be entertained, these dosage forms frequently are hypertonic and contain problematic excipients when given via the gi tract. It is generally not recommended to mix medications directly into en formula because physical incompatibilities might lead to tube occlusion. Limited data currently available indicate that acidic syrups and elixirs may be most harmful, causing physical incompatibility when admixed with en formulas.

Filtered proteins are reabsorbed in the renal tubules, which activates the tubular cells to produce inflammatory and vasoactive cytokines and triggers complement activation. These cytokines cause interstitial damage and scarring in the renal tubules, leading to damage and loss of more nephrons. Ultimately, the process leads to progressive loss of nephrons to the point where the number of remaining functioning nephrons is too small to maintain clinical stability, and kidney function declines. Assessment because ckd often presents without symptoms, assessment for ckd relies on appropriate screening strategies in all patients with risk factors for developing ckd. Evaluation for ckd and the subsequent treatment strategies depend on the diagnosis, comorbid conditions, severity and complications of disease, and risk factors for the progression of ckd. Early treatment of ckd and the associated complications of ckd are the most important factors to decrease morbidity and mortality associated with ckd. Screening for ckd should be performed in all people with an increased risk for developing ckd, including patients with dm, hypertension, genitourinary abnormalities, autoimmune disease, increased age, a family history of kidney disease, or following aki. Assessment for ckd includes measurement of scr, urinalysis, blood pressure, serum electrolytes, and/or imaging studies. A key part of ckd assessment is analysis for proteinuria, which is the primary marker of structural kidney damage, even in patients with normal gfr. Protein excretion can be assessed by measuring urine albumin-to-creatinine ration (acr), urine protein-to-creatinine ratio, or urinalysis with a reagent strip test. 3 a urinary protein excretion of 30 mg/day or more or an acr or 30mg/g (or 3. 5 mg/mmol for female and 2. 5 mg/mmol for male but varies between different guidelines and locations) or more on a random untimed urine sample is considered to be significant in the context of ckd. 1 albuminuria should be assessed with gfr at least annually in people with ckd. Assessment of protein excretion is particularly important in patients with dm, even without ckd. Screening for albumin excretion should be performed 5 years after the diagnosis of type 1 dm and at the time of diagnosis of type 2 dm. 14 complications the decline in kidney function is associated with a number of complications, which are discussed later in the chapter, including. •• hypertension •• fluid and electrolyte disorders •• anemia •• metabolic bone disease chapter 26  |  chronic and end-stage renal disease  403 treatment desired outcomes the primary goal is to slow and prevent the progression of ckd to prevent a cardiovascular event, ckd complications and the need for kidney replacement therapy. This requires early identification of patients at risk for ckd to initiate interventions early in the course of the disease. Nonpharmacologic therapy »» nutritional management reduction in dietary protein intake has been shown to slow the progression of kidney disease. 15 protein intake should be lowered to 0. 8 g/kg/day in adults with diabetes or people with a gfr less than 30 ml/min/1. 73 m2 (0. 29 ml/s/m2) who are not on dialysis.
