Abstract
Early-onset ataxia with ocular motor apraxia and hypoalbuminemia (EAOH) is one of the most common forms of autosomal recessive cerebellar ataxia. We identified six new alternative transcripts produced by the aprataxin gene responsible for EAOH. Total eight transcripts encoded truncated proteins that were located within the nucleus or cytoplasm and showed different binding abilities to wild-type (WT) aprataxin. Thus, the alternative splicing increases the molecular diversity of aprataxin and the expression profiles of these transcripts in various tissues may be related to the tissue-specific phenotypes.

Abstract
We report here a case of upper airway obstruction occurring after extubation in a 55-yr-old 60 kg man after elective nephrectomy. Anesthesia was maintained with O2 (33%), N2O, sevoflurane (1.5-2%), and propofol infusion (2 mg x kg(-1) x hr(-1)). Blood loss was 1,965 ml, part of which was substituted by blood transfusion and albumin infusion. After surgery, the patient recovered uneventfully and could be extubated shortly. Twenty minutes after extubation, he developed dyspnea progressively with stridor and became cyanotic despite the use of oxygen mask and assisted ventilation. Oxygen saturation decreased gradually, and bradycardia (<30 beats x min(-1)) and severe hypotension were also observed. Cardiopulmonary resuscitation using epinephrine was immediately started. Re-intubation of the trachea was difficult due to severe edema, but eventually performed using a tube of a smaller size (internal diameter 7.0 mm). Subsequent investigations using a fiberscope confirmed extensive soft tissue swelling, maximal at the level of the vocal cord and extending up- and down-wards to the trachea, indicating that the obstruction is caused by severe laryngeal edema. We believe that edema may have been caused by hypoalbuminemia (1.3 g x dl(-1)) at the end of operation. Therefore, it should be noted that hypoalbuminemia may cause laryngeal edema leading to acute airway obstruction.

Abstract
The current approach for therapeutic drug monitoring in renal transplant recipients receiving mycophenolate mofetil (MMF) is measurement of total mycophenolic acid (MPA) concentration. Because MPA is highly bound, during hypoalbuminemia the total concentration no longer reflects the free (pharmacologically active) concentration. The authors investigated what degree of hypoalbuminemia causes a significant change in protein binding and thus percentage free MPA. Forty-two renal transplant recipients were recruited for the study. Free and total concentrations of MPA (predose, and 1, 3, and 6 hours post-MMF dose samples) and plasma albumin concentrations were determined on day 5 posttransplantation. Six-hour area under the concentration-time curve (AUC(0-6)) values were calculated for free and total MPA, and percentage free MPA was determined for each patient. The authors found a significant relationship between low albumin concentrations and increased percentage free MPA (Spearman correlation = -0.54, P < 0.0001). Receiver operating characteristic (ROC) curve analysis was performed on the albumin versus percentage free MPA data. The cutoff value of albumin determined from the ROC analysis that differentiated normal from elevated percentage free MPA (defined as > or = 3%) in this patient population was 31 g/L. At this cutoff value albumin was found to be a good predictor of altered free MPA percentage, with a sensitivity and specificity of 0.75 and 0.80, respectively, and an area under the ROC curve of 0.79. To rationalize MMF dosing regimens in hypoalbuminemic patients (plasma albumin < or = 31 g/L), clinicians should consider monitoring the free MPA concentration.

Abstract
UNLABELLED Hypovitaminosis D has been reported in tropical countries, but this hormone has seldom been studied in Brazil. Our purpose was to study the prevalence of hypovitaminosis D in patients hospitalized in internal medicine wards in Southern Brazil. Possible associated factors were studied. We studied 81 adult patients in early spring. Mean serum 25(OH)D was 12 +/- 8.57 ng/mL; hypovitaminosis D was severe (< 10 ng/mL) in 27 (33.3%) patients, and moderate (> or = 10 ng/mL and < 20 ng/mL) in 36 (44.5%) patients. Clinical evaluation did not yield any data associated with hypovitaminosis D. Serum 25(OH)D levels of up to 20 ng/mL were associated with decreased mean serum total calcium (p = 0.001), ionized calcium (p = 0.01), and phosphorus (p = 0.044) levels, and increased mean serum PTH level (p = 0.001). In a multiple regression model, serum PTH level was independently affected by serum total calcium (p = 0.01), phosphorus (p = 0.009), and albumin (p = 0.009) levels. Hypovitaminosis D patients had lower mean serum albumin levels (p = 0.004), and serum 25(OH)D levels were directly correlated to serum albumin levels (p < 0.0001). Albumin influenced independently PTH response to hypovitaminosis D; normoalbuminemic hypovitaminosis D patients had higher mean serum PTH than hypoalbuminemic patients. CONCLUSION Hypovitaminosis D prevalence was very high in medical inpatients in Southern Brazil, in early spring. Nevertheless, secondary hyperparathyroidism was less intense in hypoalbuminemic hypovitaminosis D patients suggesting that in these patients free serum 25(OH)D was closer to normal.

Abstract
BACKGROUND It is proposed that chronic inflammation is common to the pathogenesis of malnutrition and vascular disease, both frequently observed in patients with end-stage renal disease. However, previous studies were unable to differentiate between true protein malnutrition and hypoalbuminemia. METHODS This study was undertaken to determine the associations between malnutrition, measured by total-body nitrogen (TBN), and albumin, a marker of both nutritional status and chronic inflammation, with mortality and morbidity. One hundred nine patients starting dialysis therapy underwent nutritional assessment (TBN level and anthropometric measurements), vascular risk assessment (hypertension, hypercholesterolemia, diabetes mellitus, and smoking status), and serum albumin measurement. Subsequent patient mortality and new vascular events were recorded. RESULTS Survival was associated independently with both TBN (hazard ratio [HR], 1.6; 95% confidence interval [CI], 1.1 to 2.5; P = 0.02 for every 10% decrease in nitrogen index) and serum albumin levels (HR, 1.1; 95% CI, 1.0 to 1.2; P = 0.004 for every 0.1-g/dL (1-g/L) decrease in serum albumin level) adjusted for other variables. Only low serum albumin level predicted subsequent vascular morbidity (HR, 2.2; 95% CI, 1.0 to 4.9; P = 0.049), as did increasing age (HR, 2.0; 95% CI, 1.4 to 3.0; P = 0.0004 for every 10-year increase in age) adjusted for other important risk factors. CONCLUSION This study dissociates the effect of protein malnutrition and hypoalbuminemia on morbidity and mortality in patients starting dialysis therapy. Protein malnutrition and hypoalbuminemia are independently predictive of mortality, whereas hypoalbuminemia is predictive of vascular morbidity. The study supports the hypothesis that hypoalbuminemia is pathogenically associated with vascular disease, but dissociates this effect from protein malnutrition.

Abstract
We propose that hypoalbuminemia in preeclampsia is the result of reduced hepatic blood flow which is secondary to hypovolemia created by higher filtration pressure in the capillaries. Thus, hypoalbuminemia can be identified as an early sign in developing preeclampsia. We reviewed the medical records of 60 patients, aged 22-28, admitted with a diagnosis of preeclampsia during the third trimester of pregnancy. Normotensive patients served as a control group. Albumin levels were correlated with severity of the disorder. Levels between 3.0-3.5 g/dl were seen in both groups. All patients with severe preeclampsia had values below 3.0 gm/dl. Serum albumin levels may serve as an indicator of the severity of preeclampsia.

Abstract
We investigated the clinical risk factors and bacteriological examination for surgical site infection (SSI) in 144 portless endoscopic surgeries consisting of 66 clean and 78 clean-contaminated surgeries in urological diseases from April 2000 to December 2001. There were no cases of SSI in the clean surgeries. SSI occurred in 5 cases (3.5%) of clean-contaminated surgeries including total cystectomy and ileal conduit in 4 cases and total prostatectomy in 1 case. Multivariate statistical studies revealed that usage of ileum during operation and preoperative hypo-albuminemia were significant risk factors for SSI. Gram-negative rods and anaerobic bacteria were isolated from the operative wound in the total cystectomy and ileal conduit, suggesting that SSI in the operation with usage of the ileum was partially derived from contamination with endogenous bacteria, while, normal flora of the skin in the wound did not cause any post-operative SSI.

Abstract
A score based on the combination of the systemic inflammatory response and albumin hazards ratio (HR) 1.70, 95% CI 1.23 - 2.35, P=0.001) was comparable in prognostic value to that based on stage and performance status (HR 1.48, 95% CI 1.12 - 1.95, P=0.006) in patients with inoperable non-small-cell lung cancer. The former is simple to measure and well standardised.

Abstract
OBJECTIVES This study evaluated the relative contribution of serum colloid osmotic pressure (COP) lowering and pulmonary artery wedge pressure (PAWP) elevation in the pathogenesis of pulmonary edema in patients with systolic or isolated diastolic heart failure (DHF). BACKGROUND The role of hypoalbuminemia and the resulting low COP have been shown in some patients with acute systolic heart failure (SHF). Colloid osmotic pressure and PAWP were determined in 100 patients with acute heart failure (HF) (56 with DHF and 44 with SHF; mean age, 78 +/- 12 years), in 35 patients with acute dyspnea from pulmonary origin, and in 15 normal controls. Pulmonary artery wedge pressure was estimated using transthoracic Doppler echocardiography. RESULTS Colloid osmotic pressure was significantly lower in the DHF group (20.5 +/- 5 mm Hg) than in the SHF group (24.2 +/- 3.7 mm Hg, p < 0.001), pulmonary disease group (25.1 +/- 4.2 mm Hg, p < 0.001), or normal control group (24.7 +/- 3 mm Hg). Low COP resulted from hypoalbuminemia due to age, malnutrition, and sepsis. Pulmonary artery wedge pressure was significantly higher in patients with SHF (26 +/- 6.3 mm Hg) than in the patients with DHF (20.3 +/- 7 mm Hg, p < 0.001) and was significantly higher in the patients with DHF than in the patients with pulmonary disease (13 +/- 4.2 mm Hg, p < 0.001). The COP-PAWP gradient was similar in patients with SHF (-1.6 +/- 7.1 mm Hg) and patients with DHF (0.7 +/- 6 mm Hg). CONCLUSIONS Frequent hypoalbuminemia resulting in low COP facilitates the onset of pulmonary edema in patients with DHF who usually have lower PAWP than patients with SHF.

Abstract
We sought to investigate prospectively the microbial etiology and prognostic indicators of 95 institutionalized elders with severe aspiration pneumonia, and to investigate its relation to oral hygiene in using quantitative bronchial sampling. Data collection included demographic information, Activity of Daily Living, Plaque Index, antimicrobial therapy, and outcome. Out of the 67 pathogens identified, Gram-negative enteric bacilli were the predominant organisms isolated (49%), followed by anaerobic bacteria (16%), and Staphylococcus aureus (12%). The most commonly encountered anaerobes were Prevotella and Fusobacterium species. Aerobic Gram-negative bacilli were recovered in conjunction with 55% of anaerobic isolates. The Plaque Index did not differ significantly between the aerobic (2.2 +/- 0.4) and the anaerobic group (2.3 +/- 0.3). Functional status was the only determinant of the presence of anaerobic bacteria. Although seven cases with anaerobic isolates received initially inadequate antimicrobial therapy, six had effective clinical response. The crude mortality was 33% for the aerobic and 36% for the anaerobic group (p = 0.9). Stepwise multivariate analysis identified hypoalbuminemia (p < 0.001) and the burden of comorbid diseases (p < 0.001) as independent risk factors of poor outcome. In view of the rising resistance to antimicrobial agents, the importance of adding anaerobic coverage for aspiration pneumonia in institutionalized elders needs to be reexamined.

Abstract
A 52-year-old man with Chilaiditi syndrome and mental retardation was admitted to Kanagawa Rehabilitation Hospital for severe hypoglycemic coma with malnutrition. This patient was first diagnosed as partial isolated adrenocorticotropin deficiency according to his symptoms and clinical course, but he was finally diagnosed as preclinical Cushing's syndrome. Manifestations of this case seemed unusual in spite of autonomic cortisol secretion and the detailed mechanisms of symptoms were unclear. The present case indicates that preclinical Cushing's syndrome may present with various manifestations, and careful diagnosis is necessary.

Abstract
BACKGROUND In the general population, a mildly elevated plasma total homocysteine (tHcy) level is an independent and graded risk factor for cardiovascular disease (CVD). In patients with end-stage renal disease (ESRD), CVD is highly prevalent and a major cause of premature mortality, and plasma tHcy levels are as much as three to four times greater than in the general population. Several other risk factors, such as diabetes mellitus (DM), inflammation, and malnutrition, also are prevalent and contribute to CVD in patients with ESRD, and there are strong associations between inflammation, malnutrition, and hypoalbuminemia in these patients. Several investigations in patients with ESRD have shown the important role of vitamin status for plasma tHcy, but little attention has been given to the influence of nutritional status. However, it is obvious that hypoalbuminemia is of interest because a substantial fraction of tHcy (>70%) is protein bound, mainly to albumin. RESULTS In studies of patients with ESRD in whom the prevalence of hyperhomocysteinemia was very high (>90%), tHcy level was strongly related to serum albumin level, and patients with malnutrition had lower levels of both tHcy and serum albumin than those with normal nutritional status. Furthermore, inflammation, DM, and CVD are associated with hypoalbuminemia and therefore a lower degree of hyperhomocysteinemia. In our studies, in different groups of patients with ESRD, we showed that greater tHcy levels were associated with lower CVD mortality. However, this apparently paradoxical association between lower CVD mortality and lower plasma tHcy levels (although still abnormally high) does not refute the concept that hyperhomocysteinemia is a risk factor for CVD because almost all patients may have had long-standing elevated plasma tHcy levels within a range that makes them prone to develop atherosclerosis. Instead, a potentially detrimental effect of hyperhomocysteinemia on CVD in patients with ESRD may be obscured by the influence of hypoalbuminemia, whatever the cause, because hypoalbuminemia and its causes are strong predictors of mortality. CONCLUSION Our findings imply that nutritional status and serum albumin level, as well as the presence of inflammation and DM, should be taken into consideration when evaluating tHcy as a risk factor for CVD in patients with ESRD.

Abstract
BACKGROUND Both peritonitis and serum albumin level are associated with morbidity and mortality in peritoneal dialysis (PD) patients. Severe cases of peritonitis result in hypoalbuminemia. However, it is not clear whether hypoalbuminemia predicts the development of peritonitis. METHODS We performed a retrospective analysis of a prospectively collected database from six centers in western Pennsylvania and West Virginia. Incident PD patients with a Charlson Comorbidity Index (CCI) score at the start of PD therapy and serum albumin level measured within 30 days of initiation were selected. Poisson regression was used to analyze predictors of peritonitis. RESULTS Three hundred ninety-three patients had a CCI score and serum albumin level measured at the start of PD therapy. Overall peritonitis rate was 0.65 episodes/dialysis-year. Significant univariate predictors were albumin level (rate ratio [RR], 0.79 per 1-g/dL [10-g/L] increase; 95% confidence interval [CI], 0.65 to 0.95; P = 0.015), male sex (P = 0.003), and being dialyzed in the Veterans Administration (RR, 1.97; 95% CI, 1.48 to 2.62; P < 0.001) or other center (RR, 1.68; 95% CI, 1.92 to 5.62; P < 0.001). Although CCI score correlated inversely with albumin level (r = -0.305; P < 0.001), CCI score was only marginally predictive of peritonitis (P = 0.068). In multivariate analysis, predictors were albumin level (RR, 0.74; 95% CI, 0.31 to 1.75; P = 0.002) and race (RR, 1.36; P = 0.024). Patients with an initial serum albumin level less than 2.9 g/dL (29 g/L) had a peritonitis rate of 1.5 episodes/dialysis-year compared with 0.6 episodes/dialysis-year for patients with an initial serum albumin level of 2.9 g/dL or greater (P < 0.001). CONCLUSION Hypoalbuminemia at the start of PD therapy is an independent predictor of subsequent peritonitis. Intervention studies to decrease peritonitis risk in this high-risk subset of patients are needed.

Two dogs were emaciated and hypoalbuminemic due to protein-losing enteropathy associated with a severe, focal, mucoid, cryptal ectasia of the duodenum and marked villus atrophy. In one case, diseased portions of the duodenum were obvious endoscopically and were limited to discrete, focal areas in the small intestine, with apparently more undiseased tissue than diseased tissue being present. The signs and lesions in one dog resolved after initiating combination dietary and pharmacological therapy.

Abstract
BACKGROUND Dyslipidemia frequently complicates chronic nephropathies and increases the risk of renal and cardiovascular events. This might be ameliorated by drugs, such as angiotensin-converting enzyme inhibitors, which effectively reduce proteinuria. METHODS AND RESULTS In this longitudinal study, we evaluated the extent to which uptitration of the ACE inhibitor lisinopril to maximum tolerated doses (median [range]: 30 [10 to 40] mg/d) ameliorated proteinuria and dyslipidemia in 28 patients with nondiabetic chronic nephropathies. Maximum lisinopril doses significantly and safely reduced proteinuria, serum total, LDL cholesterol, and triglycerides without substantially affecting serum HDL and renal hemodynamics. Proteinuria already decreased at 10 mg/d. Serum lipids progressively and dose-dependently decreased during uptitration to maximum doses. Reduction in total and LDL cholesterol correlated with increases in serum albumin/total protein concentration and oncotic pressure, peaked at lisinopril maximum doses, and persisted after treatment withdrawal. Despite less proteinuria reduction, hypercholesterolemia decreased more (and reflected the increase in serum albumin) in hypoalbuminemic than in normoalbuminemic patients who, despite more proteinuria reduction, had less decrease in cholesterol and no changes in serum albumin. Changes in serum triglycerides were independent of changes in serum proteins, were strongly correlated with lisinopril doses (r=-0.89, P=0.003) and recovered promptly after treatment withdrawal. Lisinopril was well tolerated, did not affect renal hemodynamics, and caused symptomatic, reversible hypotension in only two patients. CONCLUSIONS In chronic nephropathies, angiotensin converting enzyme inhibitor uptitration to maximum tolerated doses safely ameliorated hypertriglyceridemia by a direct, dose-dependent effect, and hypercholesterolemia through amelioration of the nephrotic syndrome, particularly in patients with more severe hypoalbuminemia.

Abstract
BACKGROUND Onset of ulcerative colitis and Crohn disease after the age of 65 (late-onset disease) is not common, and is usually associated with a worse prognosis. We review our experience with late-onset ulcerative colitis and define the predictors of short-term outcome. METHODS A retrospective analysis of our surgical experience with 33 patients suffering from late-onset ulcerative colitis. The medical records of 17 women and 16 men who had surgery between 1984 and 1999 were reviewed for age at surgery, sex, duration of disease, extent of disease, indications for surgery, surgical procedures and outcome. Additionally, we identified predictors of outcome. RESULTS The median age at surgery was 74 years (range 65-83). The most common indication for surgery was refractoriness to medical treatment. There were 4 deaths for a mortality rate of 12%, and 7 major complications. There was no mortality for elective procedures. On univariate analysis, albumin levels of 2.8 g/dl or less and urgent surgery were predictors of poor outcome. Disease of short duration (3 years or less from onset of disease to surgery) was also associated with a poor outcome, but this did not reach statistical significance. CONCLUSIONS We conclude that in the elderly population suffering from late-onset ulcerative colitis and requiring an operation, urgent surgery and hypoalbuminemia are predictors of adverse outcome. Age at surgery, sex and the extent of colonic involvement did not influence outcome. Low complication and death rates should be expected for elective procedures in the elderly.

Abstract
Two juvenile male Speke's gazelles (Gazella spekei) at the St. Louis Zoo showed poor body condition, slowed growth, hunched stance, rough hair coat, and profound hypophosphatemia. The first gazelle was treated with parenteral phosphorous supplements but continued to deteriorate clinically and was euthanatized. The second gazelle had serum 25-hydroxyvitamin D levels of 0 nmol/L and was treated with i.m. injections of vitamin D. It died shortly after starting therapy. The only significant necropsy finding was multiple rib fractures in various stages of healing. Hypovitaminosis D has been confirmed in multiple Speke's gazelles in this collection, indicating possible deficiencies in the diet or in the amount of ultraviolet light available to the gazelles.
