Langerhans cell histiocytosis in children with refractory diarrhoea and hypoalbuminaemia as the initial presentation: two case reports and a literature review.

Langerhans cell histiocytosis (LCH) involving the gastrointestinal tract is a rare condition for which clinical experience is limited. We describe the cases of two patients who initially presented with chronic diarrhoea, hypoproteinaemia, and intermittent fever. These findings suggest that in cases of refractory diarrhoea accompanied by recurrent hypoalbuminaemia, especially with abdominal rash, LCH should be considered. Gastrointestinal endoscopy, biopsy, and imaging studies are essential for obtaining a definitive diagnosis. This approach might be helpful for the early recognition of gastrointestinal tract involvement in LCH.

The effect of albumin and hemoglobin levels on the prognosis of early-stage cervical cancer: a prospective, single-center-based cohort study.

BACKGROUND: Serum albumin (ALB) and hemoglobin (HGB) are important serum biochemical indices of the nutritional status of patients and are associated with cancer development. We investigated the relationship between ALB and HGB levels and clinicopathologic characteristics of early-stage cervical cancer to determine the influence of ALB and HGB on the prognosis of early-stage cervical cancer. METHODS: The clinical data of 560 patients with International Federation of Gynaecology and Obstetrics (FIGO, 2009) stage IA1-IIA2 cervical cancer from January 2005 to December 2010 were retrospectively analyzed. The relationship between serum ALB and HGB levels and clinicopathological characteristics of patients were analyzed. The patients were followed-up for 12-138 months. The effects of ALB and HGB levels on the prognosis were analyzed by Cox regression, log-rank test, and the Kaplan-Meier method. RESULTS: The rate of patients with pelvic lymph node metastasis (PLNM), tumor diameter ≥ 4 cm, lymphovascular space invasion (LVSI), and deep stromal invasion was significantly higher in the anemia and hypoalbuminemia group than in the normal group (P < 0.05). The progression-free survival (PFS) and overall survival (OS) of patients in the hypoalbuminemia group and anemia group were significantly lower than that of the normal group (P < 0.05). FIGO stage, tumor diameter, PLNM, depth of stromal invasion, LVSI, the levels of ALB and HGB were risk factors for the prognosis of cervical cancer patients (P < 0.05). CONCLUSION: Patients with hypoproteinemia and anemia in early-stage cervical cancer are more likely to have higher tumor stage, larger tumor size, PLNM, LVSI, and deep stromal invasion. In addition, patients with hypoproteinemia and anemia have a poorer prognosis than those without the condition. Therefore, it is of great significance to detect the ALB and HGB levels of patients and improve the nutritional status of patients in a timely manner for better prognosis of cervical cancer.

Prognostic value of computed tomography associated body composition measurement changes in metastatic colorectal cancer patients.

BACKGROUND: Sarcopenia is associated with poor prognosis in metastatic colorectal cancer (mCRC) patients. PURPOSE: To investigate the prognostic value of body composition measurement changes measured by computed tomography (CT) in mCRC patients. MATERIAL AND METHODS: The abdominal skeletal muscle density (SMD) and skeletal muscle (SMI) indices, as well as the visceral (VATI) and subcutaneous fat tissue (SATI) indices, were calculated by automatic segmentation method on the abdominal CT images obtained before (n = 71) and after chemotherapy (n = 52). Skeletal muscle gauge (SMG = SMD × SMI) was calculated. We calculated the percentage change of body composition measurements with respect to the first measurements. The cutoff value for the change in SMG was calculated by receiver operating characteristic analysis. Kaplan-Meier and Cox regression analyses were performed to calculate the prognostic value of age, gender, tumor location, metastasis site and carcinoembriogenic antigen (CEA) elevation, hypoalbuminemia, body mass index classification, presence of sarcopenia and SMG changes in terms of overall survival. RESULTS: There was a significant association between SMG change and mortality (P = 0.037). According to survival analyses, highly decreased SMG, hypoalbuminemia and CEA variables of the patients were the significant factors (P < 0.001, P = 0.015 and P = 0.019, respectively). According to multivariate regression analysis, hypoalbuminemia (P = 0.004, hazard ratio = 3.60) and highly decreased SMG (P < 0.001, hazard ratio = 14.98) were found to be significant prognostic factors together. CONCLUSION: In mCRC patients, hypoalbuminemia and highly decreased SMG are significant prognostic factors for overall survival. Therefore, we suggest that the change in SMG calculated in follow-up images should also be evaluated in the prognosis estimation of this patient group.

Variations in the Human Serum Albumin Gene: Molecular and Functional Aspects.

The human albumin gene, the most abundant serum protein, is located in the long arm of chromosome 4, near the centromere, position 4q11-3. It is divided by 14 intervening introns into 15 exons, the last of which is untranslated. To date, 74 nucleotide substitutions (mainly missense) have been reported, determining the circulating variants of albumin or pre-albumin. In a heterozygous state, this condition is known as alloalbuminaemia or bisalbuminaemia (OMIM # 103600). The genetic variants are not associated with disease, neither in the heterozygous nor in the homozygous form. Only the variants resulting in familial dysalbuminaemic hyperthyroxinaemia and hypertriiodothyroninaemia are of clinical relevance because affected individuals are at risk of inappropriate treatment or may have adverse drug effects. In 28 other cases, the pathogenic variants (mainly affecting splicing, nonsense, and deletions), mostly in the homozygous form, cause a premature stop in the synthesis of the protein and lead to the condition known as congenital analbuminaemia. In this review, we will summarize the current knowledge of genetic and molecular aspects, functional consequences and potential therapeutic uses of the variants. We will also discuss the molecular defects resulting in congenital analbuminaemia, as well as the biochemical and clinical features of this rare condition.

Hypoalbuminemia as a prognostic biomarker for higher mortality and treatment complications in acute myeloid leukemia.

Older age and poor performance status lead to worse outcomes in acute myeloid leukemia (AML) patients. Hypoalbuminemia is a negative predictor of morbidity and mortality in several malignancies. We evaluated the relationship between baseline serum albumin levels on treatment-related complications, as well as short-term mortality and overall survival (OS) in 756 newly diagnosed AML patients. We conducted a retrospective multicenter study to examine treatment-related complications and OS according to pretreatment serum albumin levels: normal albumin ≥3.5 g/dl, marked hypoalbuminemia <2.5 g/dl, and hypoalbuminemia 2.5-3.4 g/dl. In an adjusted multivariate analysis, a lower baseline albumin was independently associated with a higher number of grade ≥3 complications when adjusting for age, secondary AML, sex and intensive treatment. When comparing normal to markedly low albumin levels, the estimated mean number of complications increases by a factor of 1.35. Patients who had a normal baseline albumin had a 30 day-mortality rate of 4.8%, which was significantly lower compared with patients with hypoalbuminemia (16.5%) and marked hypoalbuminemia (33.9%; p < 0.01). Similarly, 60-day mortality rate was significantly higher in the hypoalbuminemia group (24.0%) and marked hypoalbuminemia group (45%) compared with normal albumin group (8.3%; p < 0.01). Patients with lower baseline albumin levels have increased treatment-related morbidity and mortality, suggesting that pre-treatment serum albumin is an important independent prognostic marker.

Maximal diameter of liver abscess independently predicts prolonged hospitalization and poor prognosis in patients with pyogenic liver abscess.

BACKGROUND/AIMS: This study aimed to investigate the factors associated with prolonged hospital stay and in-hospital mortality in patients with pyogenic liver abscess. METHODS: We retrospectively reviewed data from patients with pyogenic liver abscess who were admitted between 2005 and 2018 at three tertiary hospitals in Jeonbuk province, South Korea. Prolonged hospital stay was defined as a duration of hospital admission of more than 21 days. RESULTS: A total of 648 patients (406 men and 242 women) diagnosed with pyogenic liver abscess were enrolled in the study. The mean maximal diameter of the liver abscess was 5.4 ± 2.6 cm, and 74.9% of the lesions were single. The three groups were divided according to the maximal diameter of the abscess. Laboratory parameters indicated a more severe inflammatory state and higher incidence of complications and extrahepatic manifestations with increasing abscess size. Rates of percutaneous catheter drainage (PCD) insertion, multiple PCD drainage, and salvage procedures as well as duration of drainage were also higher in the large liver abscess group. Of note, the duration of hospitalization and in-hospital mortality were significantly higher in the large hepatic abscess group. A multivariate analysis revealed that underlying diabetes mellitus, hypoalbuminemia, high baseline high-sensitivity C-reactive protein (hs-CRP) and procalcitonin levels, and large maximal abscess diameter were independent factors associated with prolonged hospital stay. Regarding in-hospital mortality, acute kidney injury at admission and maximal diameter of the abscess were independent factors associated with in-hospital mortality. CONCLUSIONS: A large maximal diameter of the liver abscess at admission indicated prolonged hospitalization and poor prognosis. More aggressive treatment strategies with careful monitoring are warranted in patients with large liver abscesses.

Hypoalbuminemia as Surrogate and Culprit of Infections.

Hypoalbuminemia is associated with the acquisition and severity of infectious diseases, and intact innate and adaptive immune responses depend on albumin. Albumin oxidation and breakdown affect interactions with bioactive lipid mediators that play important roles in antimicrobial defense and repair. There is bio-mechanistic plausibility for a causal link between hypoalbuminemia and increased risks of primary and secondary infections. Serum albumin levels have prognostic value for complications in viral, bacterial and fungal infections, and for infectious complications of non-infective chronic conditions. Hypoalbuminemia predicts the development of healthcare-associated infections, particularly with Clostridium difficile. In coronavirus disease 2019, hypoalbuminemia correlates with viral load and degree of acute lung injury and organ dysfunction. Non-oncotic properties of albumin affect the pharmacokinetics and pharmacodynamics of antimicrobials. Low serum albumin is associated with inadequate antimicrobial treatment. Infusion of human albumin solution (HAS) supplements endogenous albumin in patients with cirrhosis of the liver and effectively supported antimicrobial therapy in randomized controlled trials (RCTs). Evidence of the beneficial effects of HAS on infections in hypoalbuminemic patients without cirrhosis is largely observational. Prospective RCTs are underway and, if hypotheses are confirmed, could lead to changes in clinical practice for the management of hypoalbuminemic patients with infections or at risk of infectious complications.

Calcium state estimation by total calcium: the evidence to end the never-ending story.

Background Total blood calcium (TCa) is routinely used to diagnose and manage mineral and bone metabolism disorders. Numerous laboratories adjust TCa by albumin, though literature suggests there are some limits to this approach. Here we report a large retrospective study on agreement rate between ionized calcium (iCa) measurement and TCa or albumin-adjusted calcium measurements. Methods We retrospectively selected 5055 samples with simultaneous measurements of iCa, TCa, albumin and pH. We subgrouped our patients according to their estimated glomerular filtration rate (eGFR), albumin levels and pH. We analyzed each patient's calcium state with iCa as reference to determine agreement rate with TCa and albumin-adjusted calcium using Payne, Clase, Jain and Ridefelt formulas. Results The Payne formula performed poorly in patients with abnormal albumin, eGFR or pH levels. In patients with low albumin levels or blood pH disorders, Payne-adjusted calcium may overestimate the calcium state in up to 80% of cases. Similarly, TCa has better agreement with iCa in the case of hypoalbuminemia, but performed similarly to the Payne formula in patients with physiological albumin levels. The global agreement rate for Clase, Jain and Ridefelt formulas suggests significant improvement compared to Payne calcium adjustment but no significant improvement compared to TCa. Conclusions Total and albumin-adjusted calcium measurement leads to a misclassification of calcium status. Moreover, accurate calcium state determination depends on blood pH levels, whose measurement requires the same pre-analytical restrictions as iCa measurement. We propose that iCa should instead become the reference method to determine the real calcium state.

Hypoalbuminemia differently affects the serum bone turnover markers in hemodialysis patients.

Renal osteodystrophy (ROD) represents bone disorders related to chronic kidney disease (CKD) and several bone biomarkers are used clinically to predict ROD in CKD and hemodialysis (HD) patients. Serum albumin associates with inflammation other than nutritional status in these patients. Chronic inflammation is proved to relate with bone loss, however, the influence of hypoalbuminemia on bone biomarkers is still unclear. In this study, we evaluated the pattern of bone biomarker changes and further studied the influence of hypoalbuminemia on these biomarkers. A total of 300 maintenance HD patients were evaluated and 223 HD patients were included in the study. The patients were grouped according to serum parathyroid hormone (PTH) levels (PTH ≤150 pg/mL, PTH 150-300 pg/mL, PTH 300-600 pg/mL and PTH >600 pg/mL). Bone biomarkers and inflammatory markers were measured and their relation with PTH levels was determined. Significantly increased interleukin-6 (IL-6) and lower albumin levels were noted among PTH>600 pg/mL group. Bone turnover markers were significantly higher in PTH >600 pg/mL group (p< 0.05). Hypoalbuminemia significantly increased the fibroblast growth factor-23 (FGF-23) and procollagen type 1N-terminal propeptide (P1NP) in PTH ≤150 pg/mL, PTH 150-300 pg/mL, PTH 300-600 pg/mL groups, whereas no such relation was noted among PTH> 600 ng/dL group. In conclusion, hypoalbuminemia represents a chronic inflammation which differently relates to bone turnover markers according to serum PTH levels in SHPT patients. Thus, serum albumin measurement should be considered in determining bone disorders among these patients.

Clinical Features of Nephrotic Syndrome with Cerebral Hemorrhage.

BACKGROUND Cerebral hemorrhage has been increasingly reported in patients with nephrotic syndrome (NS). However, the clinical features and pathogenesis of NS patients with cerebral hemorrhage remain unclear. MATERIAL AND METHODS From January 2007 to August 2017, continuous NS patients with cerebral hemorrhage at the First Affiliated Hospital of Guangxi Medical University were selected. The clinical manifestations, laboratory measurements, and neurological images of these patients were collected and analyzed. RESULTS Acute cerebral hemorrhage was recorded in 15 of 10 461 NS patients. The average age of these 15 patients (9 males and 6 females) was 50.87±23.27 years old. Among these 15 patients, conventional vascular risk factors were identified in 8 patients, hypoalbuminemia and proteinuria were recorded in all 15 patients, coagulopathy was observed in 9 patients, increased D-dimer level was recorded in 13 patients, hyperlipidemia was recorded in 11 patients, and impaired renal function was recorded in 9 patients. The hemorrhage developed in the lobe (n=9), basal ganglia (n=3), cerebellum (n=2), and cerebral hemisphere (n=1). Eight patients were in a coma on the day the cerebral hemorrhage occurred, while 12 patients had a poor prognosis after 30 days of hemorrhage onset. CONCLUSIONS Poor prognosis was recorded in NS patients with cerebral hemorrhage. Although conventional vascular risk factors have only been identified in 8 patients, biochemical abnormalities (hypoalbuminemia, proteinuria, elevated D-dimer, and hyperlipidemia) were recorded in the majority of these 15 patients. Furthermore, most of the hemorrhages developed in the lobes. Coagulopathy might be the potential pathogenesis of cerebral hemorrhage in NS patients.

Retinal and choroidal thickness in paediatric patients with hypoalbuminaemia caused by nephrotic syndrome.

BACKGROUND: A study was conducted to evaluate the choroidal thickness (CT) and retinal thickness (RT) in paediatric patients with hypoalbuminaemia caused by nephrotic syndrome (NS). We also studied the correlation between the subfoveal choroidal thickness (SFCT) and serum protein concentration. METHODS: This was a cross-sectional study. Fifty-one paediatric patients with hypoalbuminaemia caused by NS and 41 normal subjects were included in the study. Enhanced depth imaging optical coherence tomography (EDI-OCT) was performed to measure the RT and CT. The RT and CT were measured manually at intervals of 0.5 mm along a horizontal line through the macular fovea between 2.5 mm nasal and 2.5 mm temporal to the fovea. Clinical data including measurements of serum proteins were obtained. RESULTS: The mean RTs at the T2.5, T2, N1.5, N2, and N2.5 locations and the average macular horizontal RT were slightly greater in the NS group than those in the control group. The mean CTs at all locations were significantly greater in the NS group than those in the control group; the difference was most significant at the fovea (373.8 ± 74.9 µm vs. 280.2 ± 57.1; p < 0.001). The SFCT in patients with NS was correlated with age (r = - 0.307, p = 0.003), body height (r = - 0.320, p = 0.022), body weight (r = - 0.343, p = 0.014), axial length (AL, r = - 0.237, p = 0.023), total protein (TP, r = - 0.302, p = 0.031), albumin (ALB, r = - 0.285, p = 0.042), prealbumin (PA, r = - 0.303, p = 0.033) and 24-h urine volume (UV, r = - 0.298, p = 0.034). Multiple linear regression analysis showed that the TP concentration and body weight had the highest correlation with the SFCT (R2 = 0.220, p < 0.05). CONCLUSIONS: The macular RT is slightly increased and the macular CT is significantly increased in paediatric patients with hypoalbuminaemia caused by NS, indicating fluid accumulation in the retina and choroid. There is a negative correlation between the SFCT and serum TP concentration. Thus, the serum TP concentration is an important indicator of CT in patients with hypoalbuminaemia.

Hypoalbuminaemia segregates different prognostic subgroups within the refined standard risk acute graft-versus-host disease score.

Hypoalbuminaemia has been previously described to predict worse non-relapse mortality (NRM) and inferior overall survival (OS) in allogeneic haematopoietic cell transplant (allo-HCT) recipients. Here, we evaluate the role of hypoalbuminaemia (<35 g/l) at time of onset of acute graft-versus-host disease (aGVHD) when incorporated into the refined aGVHD score. The study population consisted of 522 patients, median age 53 (18-75) years, who underwent an allo-HCT mostly for haematological malignancies. Standard risk (SR) aGVHD comprised 467 patients (89%) and the number of high risk (HR) cases was 55 (11%). Median follow-up for all surviving patients was 26 (3-55) months. Two-year OS was significantly better in patients with SR aGVHD with a serum albumin ≥35 g/l compared to SR with albumin <35 g/l [70% (95% CI = 64-76%) vs. 49% (95% CI = 42-56%), P < 0·0001]. Also, patients with SR aGVHD and a serum albumin level of ≥35 g/l had a significantly lower NRM at 1-year post-transplantation [6% (95% CI = 3-10%) vs. 25% (95% CI = 20-32%), P < 0·0001]. After our findings are validated in a large cohort of patients, we propose that hypoalbuminaemia should be incorporated into the refined aGVHD risk score to further its ability to predict outcomes within this group.

A Host-Dependent Prognostic Model for Elderly Patients with Diffuse Large B-Cell Lymphoma.

BACKGROUND: Decision-making models for elderly patients with diffuse large B-cell lymphoma (DLBCL) treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) are in great demand. PATIENTS AND METHODS: The Society of Lymphoma Treatment in Japan (SoLT-J), in collaboration with the West-Japan Hematology and Oncology Group (West-JHOG), collected and retrospectively analyzed the clinical records of ≥65-year-old patients with DLBCL treated with R-CHOP from 19 sites across Japan to build an algorithm that can stratify adherence to R-CHOP. RESULTS: A total of 836 patients with a median age of 74 years (range, 65-96 years) were analyzed. In the SoLT-J cohort (n = 555), age >75 years, serum albumin level <3.7 g/dL, and Charlson Comorbidity Index score ≥3 were independent adverse risk factors and were defined as the Age, Comorbidities, and Albumin (ACA) index. Based on their ACA index score, patients were categorized into "excellent" (0 points), "good" (1 point), "moderate" (2 points), and "poor" (3 points) groups. This grouping effectively discriminated the 3-year overall survival rates, mean relative total doses (or relative dose intensity) of anthracycline and cyclophosphamide, unanticipated R-CHOP discontinuance rates, febrile neutropenia rates, and treatment-related death rates. Additionally, the ACA index showed comparable results for these clinical parameters when it was applied to the West-JHOG cohort (n = 281). CONCLUSION: The ACA index has the ability to stratify the prognosis, tolerability to cytotoxic drugs, and adherence to treatment of elderly patients with DLBCL treated with R-CHOP. The Oncologist 2017;22:554-560 IMPLICATIONS FOR PRACTICE: Currently, little is known regarding how to identify elderly patients with diffuse large B-cell lymphoma who may tolerate a full dose of chemotherapy or to what extent cytotoxic drugs should be reduced in some specific conditions. The Society of Lymphoma Treatment in Japan developed a host-dependent prognostic model consisting of higher age (>75 years), hypoalbuminemia (<3.7 g/dL), and higher Charlson Comorbidity Index score (≥3) for such elderly patients. This model can stratify the prognosis, tolerability to cytotoxic drugs, and adherence to treatment of these patients and thus help clinicians in formulating personalized treatment strategies for this growing patient population.

Association between hypoalbuminemia and surgical site infection in vulvar cancers.

OBJECTIVE: To determine if preoperative hypoalbuminemia is associated with postoperative wound complications among patients with vulvar cancer. METHODS: The National Surgical Quality Improvement Program database was queried for cases of vulvar cancer undergoing vulvectomy with or without lymphadenectomy (LND) from 2008 to 2013. Primary outcome was major wound complication. Secondary outcome was minor wound complication. Hypoalbuminemia was defined as albumin<3.5g/dL. Descriptive statistics and multivariable logistic regression were used for analysis. RESULTS: Of 777 vulvar cancer patients, 514 (66.2%) had vulvar surgery alone and 263 (30.3%) had a LND. Median age was 66 (range 20-90) and median BMI was 28.9kg/m(2) (range 14.3-65.5). The incidence of wound complication was 10.4% (81/777) with 48 minor and 39 major complications. There was no difference in major wound complications when a LND was performed (p=1.0). Preoperative albumin was recorded in 429 patients (55.2%). Patients with hypoalbuminemia were more likely to have a major wound complication (OR 2.9 95% CI 1.1-7.3, p=0.02), even after adjusting for BMI, age, preoperative hematocrit, and diabetes (aOR 2.7 95% CI 1.1-7.1, p=0.04). In bivariable analysis, age, diabetes, and BMI were not associated with wound complication. Patients with a wound infection had 10 times the odds of being readmitted within 30days (OR 9.5, 95% CI 4.9-18.4, p<0.01). CONCLUSIONS: Low preoperative albumin is associated with major postoperative wound complications in women undergoing surgery for vulvar cancer. When obtaining informed consent, patients with low albumin should be counseled regarding higher risks of postoperative wound complication.

A kwashiorkor case due to the use of an exclusive rice milk diet to treat atopic dermatitis.

Although several cases of severe hypoalbuminemia resulting from rice milk have been described in the past, today the use of rice milk without nutritional counseling to treat eczema is still a continuing, poor practice. We describe a kwashiorkor case in an infant with severe eczema exclusively fed with rice milk. It is well documented that rice milk is not a sufficient protein source. Moreover, only a small portion of eczema is triggered by food allergy. In conclusion this case raises the importance of managing dietary changes facing food allergies with responsibility for specialized consensus among pediatricians, nutritionists, endocrinologists and allergists all of them specialist professionals.

Severe glomerular fibrin thrombosis in a dog.

Here, we present a case of severe glomerular fibrin thrombosis in a dog with lymphoma. A 3-year-old neutered male Chihuahua presented with acute kidney injury, hypoalbuminemia, and transudate ascites. The dog showed symmetric enlargement of the spleen, which was diagnosed as B-cell lymphoma based on cytology and polymerase chain reaction tests. The dog died after intensive care, and the kidneys were removed for histopathological examination. Light microscopy, immunofluorescence, and electron microscopy analyses were performed for renal pathology; however, the findings did not support the evidence of protein-losing nephropathy. Instead, the endocapillary accumulation of fibrin thrombi was prominent in most glomeruli. A diagnosis of severe glomerular fibrin thrombosis was established, and hypoalbuminemia was considered the underlying cause of kidney damage.

Detection of circulating normal and tumor plasma cells in newly diagnosed patients of multiple myeloma and their associations with clinical and laboratory parameters.

INTRODUCTION: Circulating plasma cells (CPCs) are frequently noted in variable frequencies in the entire spectrum of plasma cells neoplasms. With advent of high sensitivity multi-parametric flow cytometry, it is not only possible to detect CPCs present in very low numbers, but also to categorise them into circulating tumor plasma cells (CTPCs) and circulating normal plasma cells (CNPCs), based on their marker-profile. This study used multi-colour flow cytometry to evaluate the load of both CTPCs & CNPCs at the time of diagnosis and at six months' time-point of therapy, and evaluated associations of both with clinical and laboratory parameters. METHODS: Twenty one newly diagnosed MM patients were enrolled. Six to nine millilitres of EDTA-anticoagulated peripheral blood sample was used for flow cytometry. A ten colour antibody panel was used for analysis of CPCs, which were categorised further into CTPCs and CNPCs. Approximately 4.8 million events were acquired for the analysis. The percentage &absolute numbers of CTPCs and CNPCs were noted and the proportion of CTPCs out of all CPCs (CTPCs + CNPCs) were also calculated for evaluating their statistical associations. RESULTS: All 21 patients of newly diagnosed MM showed presence of CPCs (CTPCs and/or CNPCs) at the time of diagnosis. The CTPCs were detected in 76 % of the study population. The median percentage and absolute counts of CTPCs were 0.52 % and 54.9 cells /µL, respectively. CNPCs were found in 95 % and the median percentage and absolute counts of CNPCs were 0.025 % and 2.66 cells/µL. After six months of therapy, CPCs (CTPCs and/or CNPCs) were found in all nine patients evaluated for this assay. CTPCs were found 33 %, with a median of 0.075 % and CNPCs were found in 89 % with a median of 0.01 %. Our study showed that the load of CTPCs was found to be higher in patients with presence of lytic bone lesions, plasmacytoma, presence of PCs on peripheral blood film by light microscopy, presence of Chr 1p32 deletion, expression of CD56 and CD81 on CTPCs, and in patients with absence of very good partial response (VGPR). Conversely, the load of CTPCs was significantly lower in patients with concomitant amyloidosis. Also, percentage of bone marrow plasma cells exhibited a significant positive correlation with the absolute count of CTPCs. We observed that the mean percentage of CNPCs was significantly higher in female patients. The load of CNPCs was lower in patients with thrombocytopenia and with hypoalbuminemia. CONCLUSION: Increased burden of CTPCs was associated with presence of lytic lesions, plasmacytomas, Chr 1p32 deletion, expression of CD56 and CD81 on tumor cells and with failure to achieve very good partial response. The CNPCs were lower in patients with thrombocytopenia and with hypoalbuminemia. To best ot our knowledge, this is the first study from India on the relevance of circulating tumor plasma cells and the first study in the world to analyse the associations of circulating normal plasma cells in newly diagnosed patients of multiple myeloma. The study also highlights the utility of multi-parametric flow cytometry in identification and enumeration of circulating plasma cells. MICRO ABSTRACT: Circulating plasma cells indicates poorer outcomes in patients of multiple myeloma. Twenty one newly diagnosed multiple myeloma patients were evaluated by flow cytometry to enumerate and characterise circulating tumor plasma cells (CTPCs) and circulating normal plasma cells (CNPCs). Higher load of CTPCs correlated with known poor prognostic markers and poor response to therapy.

Hypoalbuminemia contributes to ascites formation via sodium and water retention: Evidence from clinical date and albumin deficient mice.

Albumin infusions improve circulatory and renal function in patients with decompensated cirrhosis. However, there is no convincing evidence that hypoalbuminemia contributes to ascites formation in liver cirrhosis. The aim of our study is to determine the exact role of hypoalbuminemia in the formation of ascites caused by liver cirrhosis and its underlying mechanism. Clinical profiles of patients with liver cirrhosis retrospectively analyzed. The details of albumin involved in ascites formation were investigated in rat model and murine model. Statistical analysis demonstrated hypoalbuminemia was an independent risk factor for ascites formation in patients with liver cirrhosis (OR = 0.722, P < 0.001). In carbon tetrachloride (CCl4)-induced rat model of liver cirrhosis, a significant reduction in serum albumin was observed in rats with ascites (13.37 g/L) compared with rats without ascites (21.43 g/L, P < 0.001). In thioacetamide (TAA)-treated mice, ascites amount of heterozygous albumin (Alb+/-) mice (112.0 mg) was larger than that of wild-type (Alb+/+) mice (58.46 mg, P < 0.001). In CCl4-induced chronic liver injury, ascites amounts of Alb+/- or Alb+/+ mice were 80.00 mg or 48.46 mg (P = 0.001). Further study demonstrated 24-h urinary sodium excretion in Alb+/- mice was lower than that of Alb+/+ mice in TAA/CCl4-induce murine models of liver cirrhosis. Additionally, serum sodium concentration of Alb+/- mice was lower than that of Alb+/+ mice. In cirrhotic mice, higher level of antidiuretic hormone was observed in Alb+/- mice compared with the control; and renal aquaporin (AQP2) expression in Alb+/- mice was significantly higher than that of WT mice. These revealed hypoalbuminemia contributed to the occurrence of ascites in liver cirrhosis through sodium and water retention.

Preoperative hypoalbuminemia is an independent predictor of poor perioperative outcomes in women undergoing open surgery for gynecologic malignancies.

OBJECTIVE: To quantify the impact of preoperative hypoalbuminemia on 30-day mortality and morbidity after gynecologic cancer surgery. METHODS: Patients included in the National Surgical Quality Improvement Program (NSQIP) dataset who underwent any non-emergent surgery for gynecologic malignancy between 1/1/2008 and 12/31/2010 were identified. Analysis was conducted with albumin both as a dichotomous variable (<3.5 g/dl was defined as low albumin) and as a continuous variable to determine a clinically relevant cut-off value. RESULTS: Of the total 3171 patients identified, 2110 had preoperative albumin levels available for analysis. In addition, 279 (13.3%) of these patients had low albumin levels. According to multivariate analysis, the low albumin group had significantly higher odds of developing one or more post-operative complications (OR-2,CI: 1.47-2.73, p<0.0001), three or more complications (OR-4.1,CI: 2.31-7.1, p<0.0001), surgical complications (OR-2.39,CI: 1.59-3.58, p<0.0001), thromboembolic complications (OR-2.59,CI: 1.33-5.06, p<0.0001), pulmonary complications (OR-4.06,CI: 2.05-8.03, p<0.0001), or infectious complications (OR-1.84,CI: 1.26-2.69, p<0.0001) and a higher 30-day mortality (OR-6.52,CI: 2.51-16.95, p<0.0001). Upon subgroup analysis, this difference was not found in patients undergoing laparoscopic surgery. In patients undergoing open surgery, the probability of experiencing one or more post-operative complications increased linearly with the decrease in albumin level; however, the probability of patients experiencing three or more complications and 30-day mortality increased sharply as soon as the albumin level decreased below 3g/dl. CONCLUSION: Preoperative albumin levels <3g/dL identify a population of patients at a very high-risk of experiencing perioperative morbidity and 30-day mortality after open surgery.

High burden of metastases and poor outcome in pelvic PNET.

Data on prognostic factors in pelvic PNET are minimal. We analyzed patients with pelvic PNET treated between June 2003 and November 2011 for prognostic factors. Forty-eight (13%) of 374 patients with PNET were pelvic PNET with median age 14.5 years (range: 5-33); 31 (65%) had metastases. After median follow-up of 20.4 months (range: 1.3-64.9), 3-year EFS, OS, and local-control-rate were 13.5 ± 5.5%, 15.4 ± 9%, and 41.3 ± 14.9%, respectively. Hypoalbuminemia (≤3.4 g/dl) predicted inferior EFS and OS for both entire cohort and metastatic group. All patients with hypoalbuminemia (n = 10) had low BMI as compared to 23/38 without hypoalbuminemia (P = 0.02).
