    ABSTRACT: We aimed to analyse the impact of psychosocial work environment on non-work-related sickness absence (NWRSA) among a prospective cohort study, stratified using a random sampling technique. Psychosocial variables were assessed among 15,643 healthy workers using a brief version of the Spanish adaptation of Copenhagen Psychosocial Questionnaire. A one year follow-up assessed the total count of NWRSA days. Zero-inflated negative binomial regression was used for multivariate analyses. After adjusting for covariates, low levels of job control and possibilities for development (Odds Ratio [OR]: 1.17; 95% CI: 1.01-1.36 [men]; OR: 1.39 95% CI: 1.09-1.77 [women]), poor social support and quality of leadership (OR: 1.29; 95% CI: 1.11-1.50 [men]; OR: 1.28; 95% CI: 1.01-1.63 [women]), and poor rewards (OR: 1.34; 95% CI: 1.14-1.57 [men]; OR: 1.30; 95% CI: 1.01-1.66 [women]) predicted a total count of sickness absence greater than zero, in both men and women. Double presence was also significantly associated with NWRSA different than 0, but only among women (OR: 1.40; 95% CI: 1.08-1.81). Analyses found no association between psychosocial risk factors at work and the total count (i.e., number of days) of sickness absences. The results suggest that work-related psychosocial factors may increase the likelihood of initiating an NWRSA episode, but were not associated with the length of the sickness absence episode. Among our large cohort we observed that some associations were gender-dependent, suggesting that future research should consider gender when designing psychosocial interventions aimed at decreasing sickness absences.

    ABSTRACT: This study investigated the sensitization pattern of crustacean allergic patients according to tolerance to molluscs. Thirty-one patients with anaphylaxis to crustaceans (14 with mollusc allergy and 17 with mollusc tolerance) were studied using skin prick tests (SPTs), specific IgEs (sIgE) and SDS-PAGE immunoblotting. IgE-reactive shrimp proteins were identified by proteomic analyses. Patients with mollusc allergy presented more frequently SPTs positive to molluscs and higher sIgE titres in response to both molluscs and crustaceans. Shrimp-sIgE and rPen a1-sIgE values of 1.57 kUA /L and 4.38 kUA /L respectively, showed positive likelihood ratios of 4.3 and 10.9 for identification of mollusc allergy. Patients with mollusc allergy reacted more frequently to tropomyosin in immunoblots than did patients without it (93% versus 35% respectively, P=0.004). Reactivity to proteins other than tropomyosin (n=14) was not different between the two groups. Among patients with crustacean anaphylaxis, patients with mollusc allergy and mollusc tolerance show a different pattern of sensitization, something that may help identify them.

    ABSTRACT: Although decreased counts of peripheral blood (PB) B cells-associated with an apparently contradictory polyclonal hypergammaglobulinemia-have been reported in chronic alcoholism, no information exists about the specific subsets of circulating B cells altered and their relationship with antibody production. Here, we analyzed for the first time the distribution of multiple maturation-associated subpopulations of PB B cells in alcoholism and its potential relationship with the onset of liver disease. PB samples from 35 male patients-20 had alcoholic hepatitis (AH) and 15 chronic alcoholism without liver disease (AWLD)-were studied, in parallel to 19 male healthy donors (controls). The distribution of PB B-cell subsets (immature/regulatory, naïve, CD27(-) and CD27(+) memory B lymphocytes, and circulating plasmablasts of distinct immunoglobulin-Ig-isotypes) was analyzed by flow cytometry. Patients with AH showed significantly decreased numbers of total PB B lymphocytes (vs. controls and AWLD), at the expense of immature, memory, and, to a lesser extent, also naïve B cells. AWLD showed reduced numbers of immature and naïve B cells (vs. controls), but higher PB counts of plasmablasts (vs. the other 2 groups). Although PB memory B cells were reduced among the patients, the percentage of surface (s)IgA(+) cells (particularly CD27(-) /sIgA(+) cells) was increased in AH, whereas both sIgG(+) and sIgA(+) memory B cells were significantly overrepresented in AWLD versus healthy donors. Regarding circulating plasmablasts, patients with AH only showed significantly reduced counts of sIgG(+) cells versus controls. In contrast, the proportion of both sIgA(+) and sIgG(+) plasmablasts-from all plasmablasts-was reduced in AH and increased in AWLD (vs. the other 2 groups). AH and AWLD patients display a significantly reduced PB B-cell count, at the expense of decreased numbers of recently produced immature/regulatory B cells and naïve B cells, together with an increase in Ig-switched memory B lymphocytes and plasmablasts, particularly of IgA(+) cells.

    ABSTRACT: Baseline serum tryptase concentrations are commonly used in clinical practice as a marker of the body's mast cell burden. This study aimed to investigate serum tryptase concentrations in heavy drinkers. Serum tryptase concentrations were determined in 126 heavy drinkers (75% males, median age 47 years) who were admitted to the hospital because of alcohol withdrawal syndrome (n = 60), general symptoms with abnormalities on biochemical tests that indicated acute liver disease (n = 19), complications of advanced liver disease (n = 33), and miscellaneous reasons (n = 14). Results were compared with those of 70 healthy controls (66% males, median age 40 years). Serum tryptase concentrations were lower in heavy drinkers than in healthy controls (median 2.23 μg/l vs. median 3.25 μg/l, p < 0.001). Ten heavy drinkers (7.9%) had undetectable (<1 μg/l) serum tryptase levels versus none of the healthy controls (p = 0.01). The association of low tryptase levels with heavy drinking was independent of age, gender, and smoking status. Among heavy drinkers, the lowest tryptase concentrations were observed in patients with alcohol withdrawal syndrome and patients with general symptoms with abnormalities on biochemical tests that indicated acute liver disease. Furthermore, serum tryptase concentrations were negatively correlated with markers of acute liver damage or alcohol consumption (serum aspartate aminotransferase and gamma-glutamyl transferase). Atopy (skin prick test positivity) was not associated with serum tryptase concentrations in heavy drinkers. Serum concentrations of mast cell tryptase are lower in heavy drinkers than in healthy controls. Copyright © 2015 by the Research Society on Alcoholism.

    ABSTRACT: Adiposity has been linked to both higher risk of asthma and reduced lung function. The effects of adiposity on asthma may depend on both atopic status and gender, while the relationship is less clear with respect to lung function. This study aimed to explore longitudinal weight changes to changes in forced expiratory volume in first second (FEV1) and forced vital capacity (FVC), as well as to incident cases of asthma and wheezing, according to atopy and gender. A general population sample aged 19-72 years was examined with the same methodology five years apart. Longitudinal changes in weight, body mass index, waist circumference, and fat percentage (bio-impedance) were analyzed with respect to changes of FEV1 and FVC (spirometry), and incidence of asthma and wheezing (questionnaire). Gender, atopy (serum specific IgE-positivity to inhalant allergens) and adipose tissue mass prior to adiposity changes were examined as potential effect modifiers. A total of 2,308 persons participated in both baseline and five-year follow-up examinations. Over the entire span of adiposity changes, adiposity gain was associated with decreasing levels of lung function, whereas adiposity loss was associated with increasing levels of lung function. All associations were dependent on gender (p-interactions < 0.0001). For one standard deviation weight gain or weight loss, FEV1 changed with (+/-)72 ml (66-78 ml) and FVC with (+/-)103 ml (94-112 ml) in males. In females FEV1 changed with (+/-) 27 ml (22-32 ml) and FVC with (+/-) 36 ml (28-44 ml). There were no changes in the FEV1/FVC-ratio. The effect of adiposity changes increased with the level of adipose tissue mass at the start of the study (baseline), thus, indicating an aggregate effect of the total adipose tissue mass. Atopy did not modify these associations. There were no statistically significant associations between changes in adiposity measures and risk of incident asthma or wheeze. Over a five-year period, increasing adiposity was associated with decreasing lung function, whereas decreasing adiposity was associated with increasing lung function. This effect was significantly greater in males than in females and increased with pre-existing adiposity, but was independent of atopy.

    ABSTRACT: Kikuchi-Fujimoto disease is a rare histiocytic necrotizing lymphadenitis that affects typically young women causing fever and painful laterocervical lymphadenopathy. The etiology is unknown, but several viral infections and autoimmune diseases have been related with the disease. Bacterial infections are less frequent. Diagnosis needs for excisional lymph node biopsy that shows paracortical areas of coagulative necrosis with abundant debris, distortion of the nodal architecture, and a large amount of histiocytes at the margins of the necrotic areas. There is no specific treatment for the disease. We present the case of a young woman with Kikuchi-Fujimoto disease associated with lower respiratory tract infection by Streptococcus pneumoniae and review the literature.

    ABSTRACT: Splenic artery aneurysm (SAA) is uncommon, but it is the most frequent visceral artery aneurysm. It is more common in women, especially during pregnancy. SAA is usually asymptomatic, but abdominal pain and rupture may develop. At present, computerized tomography (CT) angiogram is the best diagnostic test but not the only. Surgical or endovascular treatment may be considered both in symptomatic or asymptomatic aneurysms greater then 2 cm in diameter. We present the case of an elderly woman with an SAA and review the literature.

    ABSTRACT: Objective: This study aims to investigate the influence of estimated glomerular filtration rate (eGFR) with two equations (and by one or two separate measurements), on the prevalence of chronic kidney disease (CKD) and its association with blood pressure, and cardiovascular and metabolic risk factors. Methods: Between January 2010 and October 2011, the Ibermutuamur CArdiovascular RIsk Assessment project included 128 588 workers (77.2% men, mean age 39.3 years, range 16-75), who underwent two consecutive yearly medical check-ups and had information for eGFR according to the MDRD-IDMS and CKD-EPI equations (serum creatinine was measured by a isotope-dilution mass spectrometry traceable method in a single central laboratory). CKD was defined by an eGFR less than 60 ml/min per 1.73 m(2). Subclinical (occult) renal disease was defined as an eGFR less than 60 ml/min per 1.73 m(2) in patients with serum creatinine below 1.3 mg/dl and below 1.2 mg/dl in men and women, respectively. Results: In this working population, prevalence of CKD was very low, but two to six times lower when two separate eGFRs below 60 ml/min per 1.73 m(2) were used. The prevalence of CKD was significantly lower with the CKD-EPI compared to the MDRD-IDMS equation. The same applies to occult CKD. In male workers, occult CKD was practically nonexistent. Multivariate analyses show that blood pressure, total serum cholesterol, and serum glucose (positively), and high-density lipoprotein and low-density lipoprotein (negatively) were associated with CKD, with both equations. Another metabolic factor (waist circumference) was only associated (positively) with CKD defined by the CKD-EPI equation, which appears to be associated with most components of the metabolic syndrome. Conclusions: The CKD-EPI formula, calculated on the basis of two reported blood samples, may provide the most specific definition of CKD.

    ABSTRACT: Intrauterine growth has been associated with atopic conditions. Growth and adult height have been associated with cardiovascular disease, cancers and mortality but are highly genetic traits. The objectives of the study were as follows: first, to define a height measure indicating an individual's height below or above that which could be expected based on parental height (genetic inheritance) and growth charts. It was named 'the additional height index' (AHI), defined as (attained-expected) height; second, to investigate possible associations of AHI with atopic versus non-atopic health outcomes and with ischaemic heart disease (IHD) and IHD mortality. General population-based study. Research centre. A random sample of 2656 men and women living in greater Copenhagen took part in the MONICA10 study (the Danish monitoring trends and determinants of cardiovascular disease). In total, 1900 participants with information of parental height were selected. Atopic sensitisation (serum IgE), questionnaire information of atopic dermatitis, rhinoconjunctivitis, asthma or wheezing, and registry-based diagnoses of IHD/IHD mortality from National Registries. Increasing levels of AHI were inversely associated with non-atopic asthma, non-atopic wheezing, IHD and IHD mortality (IHD-all). For one SD increase of AHI, the OR or HR with CI in adjusted analyses was non-atopic asthma OR=0.52 (0.36 to 0.74), non-atopic wheezing OR=0.67 (0.51 to 0.89), and IHD-all HR=0.89 (0.78 to 1.01). The level of AHI was higher among individuals with atopic dermatitis, allergic rhinoconjunctivitis and atopic sensitisation (all p values <0.001) compared with individuals without those conditions; however, the associations were not confirmed in adjusted analyses. Individuals with childhood conditions that led them to attain tallness higher than expected from their parents' height may be at lower risk of non-atopic asthma/wheeze and IHD/IHD mortality but possibly at higher risk of atopic conditions. The measure of tallness below or above the expected height could be a sensitive alternative to normal height in epidemiological analyses.

    ABSTRACT: AimsWe investigated the potential influence of a moderate-to-high cardiovascular (CV) risk (CVR) (defined as a Systematic COronary Risk Evaluation model, or SCORE ≥ 4%), in the absence of an established CV disease, on the duration and cost of CV and non-CV sick leave (SL) resulting from common and occupational accidents or diseases.Methods and resultsWe conducted a prospective cohort study on 690 135 workers with a 1-year follow-up and examined CV- and non-CV-related SL episodes. To obtain baseline values, CVR factors were initially assessed at the beginning of the year during routine medical examination. The CVR was calculated with the SCORE charts for all subjects. Moderate-to-high CVR was defined as SCORE ≥ 4%. A baseline SCORE ≥ 4% was associated with a higher risk for long-term CV and non-CV SL, as revealed by follow-up assessment. This translated into an increased cost, estimated at €5 801 464.18 per year. Furthermore, pharmacological treatment for hypertension or hyperlipidaemia was significantly associated with longer SL duration.Conclusion Moderate-to-high CVR in asymptomatic subjects was significantly associated with the duration and cost of CV and non-CV SL. These results constitute the first body of evidence that the SCORE charts can be used to identify people with a non-established CV disease, which might ultimately translate into more lost workdays and therefore increased cost for society.

    ABSTRACT: BACKGROUND: Development of alcoholic hepatitis (AH) may be favored by the activation of the innate immune response. Recently, decreased numbers of circulating regulatory T cells (Tregs) have been reported in diseases associated with an immune activation status, but no studies have focused so far, in investigating the distribution of Tregs in chronic alcoholism and its potential association with liver disease. Here, we analyzed for the first time the frequency of peripheral blood (PB) Tregs and Treg subsets in AH and its relationship with the production of inflammatory cytokines by PB monocytes and dendritic cells (DCs). METHODS: PB samples from 25 male patients with AH were studied; in parallel, 15 male chronic alcoholic patients without liver disease (AWLD) and 17 male healthy donors were also studied, as controls. The distribution of CD4(+) CD25(hi) CD127(-/lo) Tregs and their maturation subsets (naïve, central memory, and peripheral memory Tregs) was analyzed by flow cytometry. Spontaneous and in vitro-stimulated production of inflammatory cytokines by PB monocytes and DCs was analyzed by flow cytometry at the cytoplasmic level. RESULTS: Patients with AH showed decreased (p < 0.05) numbers of PB CD4(+) CD25(hi) CD127(-/lo) Tregs at the expense of all maturation-associated subsets, while AWLD and healthy subjects showed a similar (p > 0.05) distribution of PB CD4(+) CD25(hi) CD127(-/lo) Tregs. Interestingly, significantly increased amounts of spontaneously produced inflammatory cytokines were found among circulating monocyte-derived DCs and monocytes from AH (and AWLD) patients in comparison with healthy donors. Conversely, the ability of these cell subsets to produce cytokines after in vitro stimulation was lower (p < 0.05) in AH versus the 2 control groups. CONCLUSIONS: PB CD4(+) CD25(hi) CD127(-/lo) Tregs are significantly decreased in patients with AH when compared to both healthy and AWLD; this may contribute to explain the more pronounced activation of the innate immune response observed in AH, as reflected by an increased secretion of inflammatory cytokines by PB DCs and monocytes, and could facilitate the development of liver disease.

    ABSTRACT: Background: Although the prevalence of chronic kidney disease (CKD) is 10–14%, several prospective studies note a low rate of progression to end-stage renal disease (ESRD) in stages 3 and 4. A correct classification of risk of progression, based on demonstrated predictive factors, would allow better management of CKD. Recent studies have demonstrated the high predictive value of a classification that combines estimated (e) glomerular filtration rate (GFR) and urine albumin–creatinine ratio (ACR). We estimated the clinical risk of progression to ESRD and cardiovascular mortality predicted by the combined variable of eGFR and ACR in the Spanish general population. Materials and Methods: This study was a cross-sectional evaluation in the Epirce sample, representative of Spanish population older than 20 years. GFR was estimated using MDRD and CKD-EPI formulas; microalbuminuria was considered to be an ACR 20–200 mg/g (men) or 30–300 mg/g (women) and macroalbuminuria was indicated beyond these limits. Population-weighted prevalence of risk of progression of CKD to ESRD was estimated. Results: With MDRD, 1.4% of the adult Spanish population was at moderate risk of progression to ESRD, 0.1% at high risk, and 12.3% at low risk. With CKD-EPI, the moderate risk ratio rose to 1.7% and low risk to 12.6%, but high risk remained stable. Conclusions: The addition of ACR to eGFR best classifies the population at risk for renal impairment relative to Kidney/Disease Outcomes Quality Initiative grades 3 and 4. Estimating GFR with CKD-EPI modifies the distribution of low and moderate risk.

    ABSTRACT: Background: Loss-of-function mutations of the filaggrin (FLG) gene cause an impaired skin barrier and increase the risk of atopic dermatitis. Interestingly, FLG mutations have also been found to be associated with a high risk of peanut allergy. Objective: We investigated the association of FLG mutations with self-reported food allergy, symptoms of oral allergy syndrome (OAS), and alcohol sensitivity. Methods: A total of 3,471 adults from the general population participated in a health examination. Information on food allergies, OAS and alcohol sensitivity was obtained by questionnaire. FLG mutation carriers were defined as having at least one null mutation allele of R501X or 2282del4. Primary lactose intolerance (PLI) was defined as the C/C genotype of the rs4988235 polymorphism. Results: FLG mutations were associated with a higher risk of self-reported allergy to eggs (OR 3.22 and 95% CI 1.46-7.11), milk (OR 2.10 and 95% CI 1.12-3.92), fish (OR 4.54 and 95% CI 1.88-10.96) and wheat (OR 3.59 and 95% CI 1.61-8.02), but not with symptoms of OAS (OR 1.05 and 95% CI 0.73-1.51). Serum-specific IgE was measured in a subsample and confirmed the association between FLG and IgE to milk. A significant gene-by-gene interaction between FLG and PLI was observed in relation to self-reported allergy to milk. Furthermore, FLG mutations were associated with a higher risk of alcohol sensitivity. Conclusions: We found that loss-of-function mutations in the FLG gene were significantly associated with self-reported food allergy and alcohol sensitivity, but not with OAS. These findings, if confirmed, support the idea that skin barrier functions may be involved in the pathogenesis of food allergy.

    ABSTRACT: BACKGROUND: Asthma has been linked to obesity and the presence of the metabolic syndrome. Objective: To explore which components of the metabolic syndrome that were associated with wheezing, a main symptom of asthma. Further, to explore whether these associations were different in individuals with and without rhinitis symptoms. METHODS: We used data from the Ibermutuamur Cardiovascular Risk Assessment Plan (ICARIA) including 85,555 Spanish workers (median age = 34, range = 16-75 years) with assessments of self reported wheezing and rhinitis symptoms. Fasting blood samples were analysed for serum triglyceride (s-TG), HDL (s-HDL) and glucose; blood pressure, waist circumference (WC) and body mass index (BMI) were measured. RESULTS: In mutually adjusted analyses including all components of the metabolic syndrome and possible confounders, elevated WC (or BMI), elevated s-TG and low s-HDL were significantly associated with wheezing. Odds ratio (OR) with confidence interval (CI) were: elevated WC = 1.54 (1.46-1.62), elevated s-TG = 1.24 (1.18-1.30), low s-HDL = 1.17 (1.12-1.22). These associations were stronger in individuals without than in those with rhinitis symptoms, OR's (CI's) were WC = without rhinitis 1.70 (1.57-1.85) vs. with rhinitis 1.47 (1.37-1.58). Elevated s-TG = without rhinitis 1.36 (1.26-1.46) vs. with rhinitis 1.21 (1.13-1.29). Low s-HDL = without rhinitis 1.24 (1.15-1.34) vs. with rhinitis 1.11 (1.04-1.18). CONCLUSIONS: High s-TG and low s-HDL were associated with wheezing after adjustment for adiposity. This may substantiate elevated s-TG and lowered s-HDL as markers or inducers of inflammation associated disease. The study supports the notion that these biochemical markers have differential effects on different types of wheezing.

    ABSTRACT: Assessment of serum concentration of lipopolysaccharide (LPS)-binding protein (LBP) has been suggested as a useful biomarker to indicate activation of innate immune responses to microbial products. We investigated LBP concentrations and associations with demographics, lifestyle factors, and common metabolic abnormalities in adults. We also examined if LBP concentrations were associated with common polymorphisms in genes coding for LBP (rs2232618), CD14 (rs2569190), and TLR4 (rs4986790), the molecules responsible for the innate immune response to LPS, or serum levels of soluble CD14 (sCD14) and proinflammatory cytokines. Serum LBP was measured with a commercial immunoassay in a random sample of the adult population (n = 420, 45% males, age 18-92 years) from a single municipality. Serum LBP concentrations increased with age (P<0.001) and were higher in individuals who were overweight or obese than in normal-weight individuals (P<0.001). Similarly, LBP concentrations were higher in individuals with metabolic syndrome than in individuals without it (P<0.001). Among metabolic syndrome components, LBP concentrations were independently associated with abdominal obesity (P = 0.002) and low concentrations of HDL-cholesterol (P<0.001). Serum LBP concentrations tended to be independently associated with smoking (P = 0.05), but not with alcohol consumption. Likewise, there was not significant association between LBP concentrations and gene polymorphisms. Concentrations of LBP significantly correlated with serum levels of proinflammatory cytokines (IL-6 and IL-8), sCD14, and with liver enzymes. Serum LBP concentrations increased with age. Overweight, obesity, and having metabolic syndrome (particularly, low HDL cholesterol levels) were associated with higher LBP concentrations. These findings are consistent with microbial exposure playing a role in these inflammatory, metabolic abnormalities.

    ABSTRACT: AIMS: To investigate whether there is an association between job stress, lipid profile and dyslipidemia diagnosis. METHODS: This study used a questionnaire to evaluate job stress and lifestyle variables in 91,593 workers undergoing periodic checkups. Serum lipid levels were measured in all cases. RESULTS: The prevalence of job stress was 8.7% (95% CI, 8.5-8.8%). In bivariate analyses, job stress was significantly associated with previous dyslipidemia diagnosis (p < 0.001), lipid-lowering therapy (p < 0.001), and altered total-cholesterol (p = 0.001), HDL-cholesterol (p < 0.001) and LDL-cholesterol levels (p = 0.025). After adjusting for potential confounding variables, job stress was still associated with current dyslipidemia diagnosis (OR = 1.10; 95% CI, 1.04-1.17), high LDL-cholesterol (OR = 1.14; 95% CI, 1.05-1.23), low HDL-cholesterol (OR 1.08; 95% CI, 1.01-1.15), high total cholesterol/HDL-cholesterol ratio (OR 1.13; 95% CI, 1.05-1.23) and high LDL-cholesterol/HDL-cholesterol ratio (OR 1.11; 95% CI, 1.04-1.19). CONCLUSION: These results support the hypothesis of an association between job stress and lipid disturbances.

    ABSTRACT: Increased tryptase concentrations are a risk marker for the severity of reactions to Hymenoptera stings or venom immunotherapy To investigate serum tryptase concentrations in beekeepers with and without Hymenoptera venom allergy (HVA). Serum tryptase concentrations were measured in adult patients with HVA (n = 91, 37 of whom were beekeepers), beekeepers without HVA (n = 152), and control individuals from the general adult population (n = 246). Multivariate analyses revealed that serum tryptase levels were positively associated with beekeeping activities (P < .001) and HVA (P < .001). Tryptase levels were also positively associated with age (P < .001) and male'sex (P = .02), and negatively associated with alcoho consumption (P = .002). Beekeeping and HVA are independently associated with increased concentrations of serum tryptase.

    ABSTRACT: Background: Although the prevalence of chronic kidney disease (CKD) is 10-14%, several prospective studies note a low rate of progression to end-stage renal disease (ESRD) in stages 3 and 4. A correct classification of risk of progression, based on demonstrated predictive factors, would allow better management of CKD. Recent studies have demonstrated the high predictive value of a classification that combines estimated (e) glomerular filtration rate (GFR) and urine albumin-creatinine ratio (ACR). We estimated the clinical risk of progression to ESRD and cardiovascular mortality predicted by the combined variable of eGFR and ACR in the Spanish general population. Materials and Methods: This study was a cross-sectional evaluation in the Epirce sample, representative of Spanish population older than 20 years. GFR was estimated using MDRD and CKD-EPI formulas; microalbuminuria was considered to be an ACR 20-200 mg/g (men) or 30-300 mg/g (women) and macroalbuminuria was indicated beyond these limits. Population-weighted prevalence of risk of progression of CKD to ESRD was estimated. Results: With MDRD, 1.4% of the adult Spanish population was at moderate risk of progression to ESRD, 0.1% at high risk, and 12.3% at low risk. With CKD-EPI, the moderate risk ratio rose to 1.7% and low risk to 12.6%, but high risk remained stable. Conclusions: The addition of ACR to eGFR best classifies the population at risk for renal impairment relative to Kidney/Disease Outcomes Quality Initiative grades 3 and 4. Estimating GFR with CKD-EPI modifies the distribution of low and moderate risk.
