Abstract
CONTEXT Human studies have reported conflicting results on the association of hypoalbuminemia with osteoporosis. OBJECTIVE The aim of the study is to test the independent association between hypoalbuminemia and osteoporosis. DESIGN This is a cross-sectional observation. SETTING AND PARTICIPANTS Patients are the outpatient consecutive individuals with available clinical, laboratory, and densitometry data from 2001 to 2013 in our tertiary care academic medical center. EXPOSURE Exposure is hypoalbuminemia defined as serum albumin less than 3.5 g/dL. MAIN OUTCOME MEASURE Osteoporosis is defined as bone mineral density of 2.5 SD or less below the mean peak bone mass of young, healthy adults. RESULTS Overall, 21 121 patients were included. Mean of age was 61 years (SD 14). There were 4244 males (20.1%) and 1614 patients of African-American ethnicity (7.6%). There was a graded decrease in rate of osteoporosis from 28.0% (n = 33) at albumin of 3 g/dL or less to 9.3% (n = 1548) at albumin greater than 4 g/dL (P < .001) at the femoral neck and from 20.3% (n = 24) to 6.1% (n = 1011) at the total hip (P < .001). In a fully adjusted model, the odds of osteoporosis at albumin of 3 g/dL or less was 3.31-fold (95% confidence interval [CI] 2.08-5.28, P < .001) at the femoral neck, 2.98-fold (95% CI 1.76-5.01, P < .001) at the total hip, and 2.18-fold (95% CI 1.43-3.31, P < .001) at the lumbar spine as compared with albumin greater than 4 mg/dL. A similar independent association was identified with a longer-observed duration of hypoalbuminemia. CONCLUSION In a large population, we report an independent association of osteoporosis with lower levels of serum albumin and a longer-observed duration of hypoalbuminemia.

Abstract
Health care reform is directing clinical practice towards improving outcomes and minimizing complications. Preoperative identification of high-risk patients and modifiable risk factors present opportunity for clinical research. A total of 49,475 total hip arthroplasty patients were identified from National Surgical Quality Improvement Program between 2006 and 2013. We compared morbidly obese patients (BMI≥40 kg/m(2)) and non-morbidly obese patients (BMI 18.5-40 kg/m(2)). We also compared patients with hypoalbuminemia (serum albumin <3.5 g/dL) against those with normal albumin. Our study demonstrates that hypoalbuminemia is a significant risk factor for mortality and major morbidity among total hip arthroplasty patients, while morbid obesity was only associated with an increased risk of superficial surgical site infection. Impressively, hypoalbuminemia patients carried a 5.94-fold risk of 30-day mortality.

Abstract
OBJECTIVE To examine the association between nutritional markers at initiation and during follow up in two different cohorts of HIV-infected adults initiating highly active antiretroviral therapy (HAART) in West Africa. METHODS The ATARAO study was a one year prospective study carried in Mali. It consisted of a sample of consecutive patients initiating HAART in one of four participating centers during that period. Data were collected at time of treatment initiation (baseline) and every 3 months thereafter. The ANRS 1290 study followed Senegalese patients recruited in similar conditions. Bivariate analyses were used to identify nutritional and immunological covariates of malnutrition at baseline. Longitudinal trajectories of body mass index, hemoglobin and albumin, and their associated factors, were evaluated using mixed linear models. RESULTS In ATARAO, 250 participants were retained for analyses; of which, 36% had a BMI < 18.5 kg/m(2), nearly 60% were anemic and 47.4% hypoalbuminemic at time of treatment initiation. At baseline, low hemoglobin, hypoalbuminemia and low CD4 levels were associated with a BMI < 18.5 kg/m(2). Similarly, low BMI, low albumin and low CD4 counts were linked to anemia; while, hypoalbuminemia was associated with low hemoglobin levels and CD4 counts. In ANRS, out of the 372 participants retained for analyses, 31% had a low BMI and almost 70% were anemic. At baseline, low BMI was associated with low hemoglobin levels and CD4 counts, while anemia was associated with low CD4 counts and female sex. While treatment contributed to early gains in BMI, hemoglobin and albumin in the first 6 months of treatment, initial improvements plateaued or subsided thereafter. Despite HAART, malnutrition persisted in both cohorts after one year, especially in those who were anemic, hypoalbuminemic or had a low BMI at baseline. CONCLUSION In ATARAO and ANRS, malnutrition was common across all indicators (BMI, hemoglobin, albumin) and persisted despite treatment. Low BMI, anemia and hypoalbuminemia were associated with attrition, and with a deficient nutritional and immunological status at baseline, as well as during treatment. In spite of therapy, malnutrition is associated with negative clinical and treatment outcomes which suggests that HAART may not be sufficient to address co-existing nutritional deficiencies.

Abstract
Hemophagocytic syndrome (HPS) is a potentially life-threatening complication of systemic inflammatory disorders. Adult-onset Still disease (AOSD) is one of the systemic autoimmune diseases associated with reactive hemophagocytic syndrome (RHS). This study aimed to evaluate the characteristic findings, predictive factors, and prognosis of RHS in patients with AOSD. We retrospectively evaluated 109 patients diagnosed with AOSD and reviewed their clinical data and laboratory findings, including the biopsy results of 21 AOSD patients with RHS. Moreover, data from 17 hemophagocytic lymphohistiocytosis (HLH) patients evaluated during the same period were compared with those from the RHS patients. Twenty-one patients (19.3%) developed RHS during the course of AOSD, and only 7 patients (6.4%) were confirmed by bone marrow, liver, or lymph node biopsy. AOSD patients with RHS showed significantly higher frequencies of splenomegaly, hepatomegaly, and lymphadenopathy than did those without RHS. Moreover, patients with RHS showed significantly higher relapse rates than those without RHS (61.9% vs 18.2%, P < 0.001). Possible triggering factors inducing hemophagocytosis were detected in 16 of 21 RHS patients (76.2%): disease flare in 12 patients (75%), infection in 3 patients (18.8%), and drug use in 1 patient (6.3%). AOSD patients with RHS showed higher frequencies of leukopenia, anemia, thrombocytopenia, hypoalbuminemia, hypofibrinogenemia, hypertriglyceridemia, hyperferritinemia, and elevated lactate dehydrogenase levels than did those without RHS. Multivariate logistic regression with forward selection procedure showed that low platelet count (<121,000/mm³), anemia, and hepatomegaly were independent predictors of RHS. Patients with definite RHS and those with probable RHS showed comparable results. Although RHS is a life-threatening complication of AOSD, long-term prognosis was observed to be similar in patients with and those without RHS. Compared to RHS patients, HLH patients had poor prognosis, such as higher death rates (52.9% vs 9.5%, P = 0.005). RHS can be considered when an AOSD patient shows at least 2 of the following 3 findings: low platelet count, anemia, and hepatomegaly. Diagnostic confirmation by biopsy may not be essential if typical clinical findings of RHS are present. Moreover, prognosis of RHS was better than that of HLH diagnosed by the presence of trilineage cytopenia at admission.

Abstract
BACKGROUND Protein deficiency (PD) is a known risk factor for surgical complications; however, the risks of PD by weight class have not been well described. It was hypothesized that the combination of obesity and PD is associated with increased surgical complications compared with normal weight and normoalbuminemic patients. METHODS A total of 85,833 general surgery patients undergoing elective operations within the 2011 National Surgical Quality Improvement Program were analyzed. Patients with conditions that could potentially confound serum albumin (SA) were excluded. Patients were stratified by normal (>3.0 g/dL) versus low (<3.0 g/dL) SA. The relative impact of SA and body mass index (BMI) (as individual and as combined variables) on surgical morbidity and mortality were assessed. Multivariate analyses were performed to identify independent risk factors for morbidity and mortality. RESULTS Overall, 2,088 (2.43%) patients had low preoperative SA. 587 (28.1%) patients with low preoperative SA were obese (BMI>30), versus 39,299 (46.9%) with normal preoperative SA. Importantly, the interaction of hypoalbuminemia and BMI was independently associated with all complications among hypoalbuminemic patients with BMI>40, and mortality for patients with BMI>30 after controlling for appropriate demographic characteristics, co-morbidities, surgical wound classification, operation type, and complexity (c-statistic: .803 and .874 respectively). CONCLUSION PD and obesity appear to synergistically increase the risk of surgical complications. Paradoxically, malnutrition may be less easily recognized in obese individuals and surgeons may need to more carefully evaluate this population before surgery. Future studies should investigate therapy to correct PD specifically among obese patients before surgery.

Abstract
We report the case of a 22-year-old primiparous, admitted to our hospital with a 2-week history of vulvar edema that had evolved within 24 hours to the point of stopping urine flow and hindering ambulation. The only remarkable finding in relation with the edema was hypoalbuminemia for no apparent cause. The correction of hypoalbuminemia and the establishment of diuretic treatment, with the drainage of the edema allowed for a complete resolution of the edema.

Abstract
Hypoalbuminemia is considered an independent predictor of mortality, especially in elderly patients. It is common in patients with congestive heart failure, when is due to several mechanisms: increased volume of distribution, significant stasis in the mesenteric circulation and altered protein metabolism in the liver. These alterations are even more pregnant when tricuspid regurgitation is associated or aggravated by different risk factors (recent infections, anemia, hyperthyroidism). We present the case of an elderly patient with severe hypoproteinemia and important hypoalbuminemia associated with congestive heart failure and aggravation of tricuspid regurgitation. The differential diagnosis concluded that hypoalbuminemia was influenced by tricuspid regurgitation as it enhanced liver dysfunction and enteral protein absorption due to increased stasis in mesenteric system. On the other hand, hypoalbuminemia contributed to the progression of heart failure by favoring myocardial edema, volume overload, and diuretic resistance. This is why correct management of this situation should include removal of subclinical excess of fluid and renutrition. A multidisciplinary approach is needed in order to achieve a good control of the symptoms and a significant improvement of quality of life.

Abstract
BACKGROUND The prognostic significance of hypoalbuminemia and the dynamic changes in serum albumin during hospitalization in internal medicine wards has not been sufficiently investigated. METHODS Demographic, clinical and laboratory data were collected from 276 patients admitted to our internal medicine ward for a variety of acute disorders. Following discharge, all-cause mortality was recorded. These data were compared between patient groups, according to levels of albumin: hypoalbuminemia or normoalbuminemia (serum albumin <34 g/l and ≥ 34 g/l, respectively), on admission and discharge. RESULTS Hypoalbuminemia on admission and on discharge was found in 46% and 54% of patients, respectively. Anemia, renal dysfunction, malignant disease, hypocholesterolemia, lymphopenia and albuminuria were more prevalent in patients with hypoalbuminemia, compared to those with normoalbuminemia (p ≤ 0.03). During a median follow-up period of 23 months, 107 of 276 patients died. Mortality was significantly higher (p<0.001) in patients with hypoalbuminemia than normoalbuminemia on admission (52.0% vs. 27.5%) and on discharge (53.7% vs. 21.2%), including those admitted with normoalbuminemia and discharged with hypoalbuminemia (43.6%). Survival rate was higher for patients admitted with hypoalbuminemia and discharged with normoalbuminemia than for those remaining with hypoalbuminemia (82.4% vs. 42.8%, p=0.004). The level of albumin on discharge (each 10 g/l decrement) was the most powerful predictor of shortened survival (relative risk 2.79, 95% confidence interval 2.04-3.70). CONCLUSIONS Hypoalbuminemia on admission, as well as persistence or development of hypoalbuminemia throughout hospitalization, was associated with poor prognosis. Treatment aimed at increasing low albumin or maintaining its normal level may improve survival.

Abstract
PURPOSE OF REVIEW Diarrhea has great impact on enteral nutrition. The purpose of this review is to identify the factors leading to diarrhea during enteral nutrition and to provide the published updates on diarrhea prevention through nutritional intervention. RECENT FINDINGS Diarrhea in enteral fed patients is attributed to multiple factors, including medications (major contributor), infections, bacterial contamination, underlying disease, and enteral feeding. Diet management can alleviate diarrhea in enteral feeding. High content of fermentable oligosaccharides, disaccharides, and monosaccharides and polyols (FODMAPs) in enteral formula is postulated to induce diarrhea and lower FODMAPs formula may reduce the likelihood of diarrhea in enterally fed patients. Fiber-enriched formula can reduce the incidence of diarrhea and produce short-chain fatty acids for colonocytes. Ingesting prebiotics, nonviable probiotics or probiotic derivatives, and human lactoferrin may provide alternatives for reducing/preventing diarrhea. SUMMARY Enteral feeding is not generally considered the primary cause of diarrhea, which is frequently linked to prescribed medications. When diarrhea is apparent, healthcare members should evaluate the possible risk factors and systematically attempt to eliminate the underlying causes of diarrhea before reducing or suspending enteral feeding. Lower FODMAPs formula, prebiotics, probiotic derivatives, and lactoferrin may be used to manage enteral feeding-related diarrhea.

Abstract
OBJECTIVE Hypoalbuminemia is a common clinical deficiency in burn patients and is associated with complications related to increased extravascular fluid, including edema, abnormal healing, and susceptibility to sepsis. Some prognostic scales do not include biochemical parameters, whereas others consider them together with comorbidities. The purpose of this study was to determine whether serum albumin can predict mortality in burn patients. METHODS We studied burn patients ≥16 years of age who had complete clinical documentation, including the Abbreviated Burn Severity Index, serum albumin, globulin, and lipids. Sensitivity and specificity analyses were performed to determine the cut-off level of albumin that predicts mortality. RESULTS In our analysis of 486 patients, we found that mortality was higher for burns caused by flame (p=0.000), full-thickness burns (p=0.004), inhalation injuries (p=0.000), burns affecting >30% of the body surface area (p=0.001), and burns associated with infection (p=0.008). Protein and lipid levels were lower in the patients who died (p<0.05). Albumin levels showed the highest sensitivity and specificity (84% and 83%, respectively), and the area under the receiver-operating characteristic curve (0.869) had a cut-off of 1.95 g/dL for mortality. CONCLUSION Patients with albumin levels <2 g/dL had a mortality risk of >80%, with 84% sensitivity and 83% specificity. At admission, the albumin level could be used as a sensitive and specific marker of burn severity and an indicator of mortality.

Abstract
OBJECTIVE The aim of this study was to clarify the association between nutritional state on admission and in-hospital death in tuberculosis (TB) patients, including a high proportion of elderly patients. METHODS A retrospective cohort study of 246 TB patients was conducted. The serum albumin concentrations and peripheral blood lymphocyte counts were measured on admission, and the primary outcome of interest was in-hospital death. Patient mortality was categorized into two groups: TB death and non-TB death. A multivariate analysis was performed to evaluate the relationship between nutritional state on admission and in-hospital mortality in TB patients. RESULTS The median [interquartile range] patient age was 79 [69-83] years, and the in-hospital death rate was 20.73% (TB death: 26 patients; non-TB death: 25 patients). The multivariate analysis revealed that the serum albumin concentrations (OR: 0.21, 95% CI: 0.10-0.41; p<0.0001) and peripheral blood total lymphocyte counts (Category 2 [627.2-1,106.7/mm(3)] vs. 1 [<627.2/mm(3)]. OR: 0.28, 95% CI: 0.11-0.73; p=0.009, Category 3 [>1,106.7/mm(3)] vs. 1. OR: 0.24, 95% CI: 0.08-0.76, p=0.015) on admission were significantly associated with all in-hospital deaths in the TB patients. The serum albumin concentrations and peripheral blood total lymphocyte counts were also found to be associated with in-hospital deaths directly caused by TB. CONCLUSION Hypoalbuminemia and lymphocytopenia on admission are predictive risk factors for in-hospital mortality in TB patients. Nutritional defects should thus receive special attention in order to reduce TB patient mortality, particularly among elderly patients.

Abstract
β-Lactams are routinely prescribed in the treatment of serious infections. Empirical dosing schedules are typically derived from studies in healthy volunteers and largely fail to consider the significant changes in antibacterial pharmacokinetics often encountered in the critically ill. These changes are primarily driven by the underlying pathophysiology and the interventions provided, leading to altered protein binding, poor tissue penetration, and fluctuations in the volume of distribution and drug clearance. Each separately, and in combination, is likely to complicate successful β-lactam administration in this setting. Although antibacterial therapeutic drug monitoring (TDM) has traditionally been employed to minimise drug toxicity, the challenges to achieving 'optimal' drug concentrations in the critically ill suggest β-lactam TDM as an attractive means to optimise drug exposure. Whilst there is currently little evidence to support routine widespread application of such a service, β-lactam TDM may still have a role in select patients where difficulty in establishing therapeutic concentrations can be illustrated. This series utilises three representative cases from a β-lactam TDM service that highlight the utility of this intervention in optimising antibacterial dosing. These preliminary data support an expanding role for β-lactam TDM in select critically ill patients and provide insight into the subpopulations most at risk of suboptimal drug exposure. Future studies investigating the clinical outcome benefits of β-lactam TDM in these patient groups are now warranted.

Abstract
BACKGROUND/AIMS Anthropometric measures such as body mass index (BMI) and waist circumference (WC) have differential associations with incident chronic kidney disease (CKD) and mortality. We examined the associations of BMI and WC with various CKD complications. METHODS We conducted a cross-sectional analysis of 2,853 adult participants with CKD in the National Health and Nutrition Examination Surveys 1999-2006. The associations of BMI and WC (both as categorical and continuous variables) with CKD complications such as anemia, secondary hyperparathyroidism, hyperphosphatemia, metabolic acidosis, hypoalbuminemia and hypertension were examined using logistic regression models while adjusting for relevant confounding variables. RESULTS When examined as a continuous variable, an increase in BMI by 2 points and in WC by 5 cm was associated with higher odds of secondary hyperparathyroidism, hypoalbuminemia and hypertension among those with CKD. CKD participants with BMI ≥30 have higher odds of hypoalbuminemia and hypertension than those with BMI <30. CKD participants with high WC (>102 cm in men and >88 cm in women) have higher odds of hypoalbuminemia and hypertension and lower odds of having anemia than those with low WC. CKD participants with BMI <30 and high WC (vs. BMI <30 and low WC) were not associated with any increase in CKD complications. CONCLUSIONS Anthropometric measures such as BMI and WC are associated with secondary hyperparathyroidism, hypoalbuminemia and hypertension among adults with CKD. Higher WC among those with BMI <30 is not associated with CKD complications.

Abstract
AIM The aim of this study was to investigate the annual rate of glomerular filtration rate (GFR) decline and associated risk factors with this decline in diabetic nephropathy patients. PATIENTS AND METHODS A total of 122 type 2 diabetes mellitus (DM) patients (66F, mean follow up time 39 +/- 19 months, mean age 56 +/- 10 years, mean duration of diabetes diagnosis 12.1 +/- 9.5 years) between 2003 and 2010 were evaluated retrospectively. Socio-demographic characteristics and blood pressure data, laboratory parameters, HbAlc, daily urine protein excretion both of the first and last visits of all patients were recorded. Patients were separated into three groups according to rate of GFR decline. Group 1 (n:35), group 2 (n:42) and group 3 (n:45) consisted of patients < 1 ml/dk/1.73 m2, 1-5 ml/dk/1.73 m2 and > 5 ml/dk/1.73 m2 annual rate of GFR decline respectively. Demographics, laboratory data and their treatments were compared in all three groups and were investigated factors that may influence the rate of GFR decline. RESULTS The annual rate of GFR decline was 1.4 +/- 2.3 ml/sec, -2.9 +/- 1.0 ml/sec and -11.9 +/- 9.1 ml/sec in group 1, 2 and 3 respectively. Daily urine protein excretion was 0.9 +/- 1.3, 1.2 +/- 1.5 and 5.2 +/- 5.5 g in groups respectively, was found significantly higher in group 3 (p < 0.001). Serum albumin level was significantly lower in group 3 (p < 0.001). We found positive correlation between annual rate of GFR decline and last visit systolic blood pressure (SBP), daily proteinuria and parathormone levels (r: 0.339, 0.447 and 0.289 p < 0.001, < 0.001 and 0.02 respectively) and negative correlation between GFR decline and deltaSBP (delta systolic blood pressure), pretreatment albumin, calcium and hemoglobin levels (r: -0.409, -0.526, -0.233 and -0.467, p < 0.001, < 0.001, < 0.001 and 0.016 respectively). CONCLUSIONS Proteinuria, hypoalbuminemia, anemia, and a change in SBP were found most effective in annual rate of GFR decline in patients with diabetic nephropathy. The early detection of these factors may slow the progression of nephropathy.

Abstract
BACKGROUND Postoperative infections are frequent complications after liver resection and have significant impact on length of stay, morbidity and mortality. Surgical site infection (SSI) is the most common nosocomial infection in surgical patients, accounting for 38% of all such infections. OBJECTIVES This study aimed to identify predictors of SSI and organ space SSI after liver resection. METHODS Data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for patients who underwent liver resection in 2005, 2006 or 2007 in any of 173 hospitals throughout the USA were analysed. All patients who underwent a segmental resection, left hepatectomy, right hepatectomy or trisectionectomy were included. RESULTS The ACS-NSQIP database contained 2332 patients who underwent hepatectomy during 2005-2007. Rates of SSI varied significantly across primary procedures, ranging from 9.7% in segmental resection patients to 18.3% in trisectionectomy patients. A preoperative open wound, hypernatraemia, hypoalbuminaemia, elevated serum bilirubin, dialysis and longer operative time were independent predictors for SSI and for organ space SSI. CONCLUSIONS These findings may contribute towards the identification of patients at risk for SSI and the development of strategies to reduce the incidence of SSI and subsequent costs after liver resection.

Abstract
Congenital analbuminemia is a rare autosomal recessive disorder characterized by the absence of serum albumin, or by its presence in very low concentrations. Up to now, only 43 cases have been reported. There is little information about analbuminemia, and no operation on an analbuminemic patient has been reported. This, we believe, is the 1st report of an operation on an analbuminemic patient for coronary artery disease in which the perioperative experience is presented.

Abstract
BACKGROUND Pneumonectomy is still a high-risk surgical procedure. Postpneumonectomy bronchopleural fistula is an especially severe complication with a high mortality rate. Although several reports have discussed risk factors for early bronchopleural fistula after pneumonectomy, only a few have reported them for late bronchopleural fistula. We reviewed cases of late bronchopleural fistula after pneumonectomy and investigated its risk factors. METHODS Sixty-four patients with nonsmall cell lung cancer underwent pneumonectomy at our institution from June 1999 to December 2004. Among them, 5 who developed bronchopleural fistula were investigated. RESULTS All of the 5 patients were male; 3 had undergone right pneumonectomy and 2 left pneumonectomy. The period between surgery and the appearance of bronchopleural fistula ranged from 36 to 164 days. We found that the preoperative serum albumin level was significantly lower in the patients with late bronchopleural fistula. Induction therapy, surgical side, age, anemia, arterial blood oxygen, and respiratory function did not affect the occurrence of bronchopleural fistula after pneumonectomy. CONCLUSIONS A preoperative low-serum albumin level, indicative of poor nutritional status, is a risk factor for late bronchopleural fistula after pneumonectomy for nonsmall cell lung cancer.

Abstract
BACKGROUND The aim of this study was to evaluate the value of hypoalbuminemia or hyperglycemia as predictors for need ventilator and for weaning success in critically ill trauma patients. METHODS A single center, retrospective trial was done on 600 trauma patients = or >16 years old admitted for three or more days to the intensive care unit. Patients were classified into five different groups according to the reason for respiratory failure. The subsequent parameters were noted: serum albumin and glucose concentration, Acute Physiology and Chronic Health Evaluation III score, need ventilator, ventilator days, and fluid balance. RESULTS The initial mean serum glucose concentration was 9.3 (167.4) +/- 0.2 (3.6 mg/dl) mmol/L and the initial mean serum albumin concentration was 30.2 (3.02) +/- 0.02 (0.2 g/dl) g/L. Even though the circulating albumin concentration was considerably lower and serum glucose concentration was significantly higher in ICU nonsurvivors than in ICU survivors, neither albumin (r=-0.031, p=0.23) nor blood glucose concentration (r=0.050, p=0.11) on ICU admission was a predictor of the duration of mechanical ventilation. The profile of albumin and glucose concentration changes was dissimilar between weaned and mechanical ventilation-dependent patients. An increase of 5 g/L (0.5 g/dl) in serum albumin concentration multiplied the relative success probability by 1.10. Patients with serum albumin concentration less than 30.3 (3.03 g/dl) g/L were 1.2 times more likely to need ventilator than normo-albuminemic patients (relative risk 1.2, 95% confidence interval 1.06-1.31). The risk of need mechanical ventilation did not increase with blood glucose concentration more than 11 mmol/L (200 mg/dl). CONCLUSION These results suggest that albumin and blood glucose are possible indexes of the metabolic status of the trauma patient, which could be essential in deciding the need ventilator and weanable status of the patients who are mechanically ventilated for extended periods of time.

Abstract
Congenital analbuminemia is a rare autosomal recessive disease in which albumin is not synthesized. Patients with this disorder generally have minimal symptoms despite complete absence of the most abundant serum protein. We report a family in which the proband presented with acute glomerulonephritis and was found to have underlying congenital analbuminemia. Consequently, the patient's two older sisters were diagnosed with the same condition. Sequencing of the human serum albumin gene was performed, and a homozygous mutation in exon 3 was found in all three patients. Together with these three patients of Arab ethnicity, this mutation, known as Kayseri, is the most frequently described mutation in congenital analbuminemia. This article discusses clinical features and diagnostic challenges of this disorder, particularly in this case, where concomitant renal disease was present.

Abstract
OBJECTIVES Seriously ill patients often suffer from disorders of salt and water balance and present with clinical signs of either dehydration or oedema. The relationship of hypoalbuminaemia to oedema is complex and controversial and formed the central issue of this study. DESIGN Prospective study. SETTING Medical wards of New Somerset Secondary Hospital, November 2004. SUBJECTS 50 patients admitted consecutively to the medical wards at New Somerset Hospital were evaluated; 26 males and 24 females participated. OUTCOME MEASURES An attempt was made to correlate causes of salt and water imbalance with the clinical assessment of volume status, oedema formation, nutritional state and serum albumin levels. RESULTS Hypoalbuminaemia was not related to oedema in this study. Of 24 patients with a serum albumin level below 30 g/l, only 6 had oedema. These patients all had other abnormalities that could have resulted in the oedema, notably primary salt retention by failing kidneys, cor pulmonale and malignancy. None of the patients with serum albumin levels below 15 g/l had any signs of oedema. The combined insult of a chronic inflammatory disease and malnutrition had a marked effect on serum albumin levels. CONCLUSION Significant hypoalbuminaemia was present in many of our patients, yet oedema was detected infrequently and generally had an easily identifiable cause not related to low albumin levels. Most patients with hypoalbuminaemia presented with normal or positive water balance. This study supports the notion that hypoalbuminaemia is infrequently associated with oedema and plays a minor role in its formation.
