New-Onset Anemia and Associated Risk of ESKD and Death in Non-Dialysis CKD Patients: A Multi-Cohort Observational Study

Background

Anemia is a common complication of chronic kidney disease (CKD), but its incidence in nephrology settings is poorly investigated. Similarly, the risks of adverse outcomes associated with new-onset anemia are not known.

Methods

We performed a pooled analysis of three observational cohort studies including 1031 non-anemic CKD patients with eGFR <60 mL/min/1.73 m² regularly followed in renal clinics. We estimated the incidence of mild anemia (hemoglobin 11–12 g/dL in women and 11–13 g/dL in men) and severe anemia (hemoglobin <11 g/dL or use of erythropoiesis-stimulating agents) during a 3-year follow-up period. Thereafter we estimated the risk of end-stage kidney disease (ESKD) and all-cause death associated with new-onset mild and severe anemia.

Results

The mean age was 63 ± 14 years, 60% were men and 20% had diabetes. The mean estimated glomerular filtration rate (eGFR) was 37 ± 13 mL/min/1.73 m² and the median proteinuria was 0.4 g/day [interquartile range (IQR) 0.1–1.1]. The incidence of mild and severe anemia was 13.7/100 patients-year and 6.2/100 patients-year, respectively. Basal predictors of either mild or severe anemia were diabetes, lower hemoglobin, higher serum phosphate, eGFR <30 mL/min/1.73 m² and proteinuria >0.50 g/day. Male sex, moderate CKD (eGFR 30–44 mL/min/1.73 m²) and moderate proteinuria (0.15–0.50 g/day) predicted only mild anemia. The incidence of anemia increased progressively with CKD stages (from 8.77 to 76.59/100 patients-year) and the proteinuria category (from 13.99 to 25.02/100 patients-year). During a median follow-up of 3.1 years, 232 patients reached ESKD and 135 died. Compared with non-anemic patients, mild anemia was associated with a higher adjusted risk of ESKD {hazard ratio [HR] 1.42 [95% confidence interval (CI) 1.02–1.98]} and all-cause death [HR 1.55 (95% CI 1.04–2.32)]. Severe anemia was associated with an even higher risk of ESKD [HR 1.73 (95% CI 1.20–2.51)] and death [HR 1.83 (95% CI 1.05–3.19)].

Conclusions

New-onset anemia is frequent, particularly in patients with more severe renal damage and in those with diabetes mellitus. The occurrence of anemia, even of a mild degree, is associated with mortality risk and faster progression towards ESKD.

[Update of the Italian Society of Nephrology Project No. 1 of the 2004-2006 SIN programme]

In the last few years the Italian Society of Nephrology has addressed many technical-scientific and management aspects to better patient satisfaction. Project No. 1 of the 2004-2006 programme on 'Quality and Accreditation of National Renal Units' focuses on four essential points. The first is the questionnaire mailed to all the Presidents and Regional Delegates on the relationship between Nephrology units, Local Government Health-System and the Regional Healthcare Agency. The results evidence that the 'political' decision-making power of nephrologists decreases in the absence of a national strategy. The second point, in collaboration with the National Census Group, includes the quality analysis and the standardization of resources (human and structural) and management of the Renal Units. The third point is based on 'Educational Courses for Quality and Accreditation' held in Rome (3-5 October 2005: L'Accreditamento all'Eccellenza dell'Unita' Operativa di Nefrologia, Dialisi e Trapianto; 17-19 October 2005: Il Manuale di Accreditamento della Specialità di Nefrologia). The courses aim at training members responsible for each region to hold courses in their specific region to create a network including each single Renal Unit to create an acceptable homogenous language on the models of analysis and on the correct use of 'The Guide for Excellence Accreditation'. The fourth point concerns both the on-line Guide for Excellence Accreditation and 'Peer Review Accreditation' and the NEQUASY (Nephrology Quality System) project. The manual must be 'user friendly' allowing each Centre to self-evaluate using national and regional standards.

Hostility as a feature of elderly suicidal ideators

Literature suggests that suicidal feelings are relatively rare in mentally healthy older adults. This research investigated the presence of death or suicidal ideation in a group of home-dwelling elderly people (N = 611, M age = 75.7 yr., SD = 7.2), taking into account their psychopathological profiles assessed by means of the Brief Symptom Inventory. Suicidality was investigated by the Italian translation of the 1974 questions from Paykel, Myers, Lindenthal, and Tanner. Elderly with death or suicidal ideation manifested depressive and anxious symptoms on the Brief Symptom Inventory. This psychopathological profile, which has been reported for these subjects in various contributions to the literature, was also characterized by the presence of hostility. The correlation with higher scores on the hostility scale is difficult to interpret, although these feelings are often accompanied by failure to control impulses, which is an essential characteristic in suicidal behaviour.

Death ideation and its correlates: survey of an over-65-year-old population

The presence of dissatisfaction with life or thoughts of death or suicide has been variously surveyed in adolescent samples and in the general population, but there is a paucity of research on the elderly. The aim of this study was to assess, in an elderly community-dwelling population: a) the prevalence of death and/or suicidal feelings and thoughts and any attempted suicides; and b) factors associated with these experiences. A total of 611 over-65-year-old subjects were interviewed at home. Seventeen percent of the total (F:M = almost 2:1) responded affirmatively to at least one of the questions on suicidality. Elderly people reporting suicidal feelings presented markedly higher levels of physical and psychological distress, such as depression, anxiety, and hostility. Results indirectly confirm that depressive symptomatology is not adequately treated. Greater attention is warranted in psychological evaluation of the elderly to take into account those risk factors that, if identified and managed, could reduce the frequency of suicidal thoughts and, probably, associated actions.

Management of suicide attempts in Italy and Sweden. A comparison of services offered to consecutive samples of suicide attempters

The aim of the study was to compare the management of suicide attempts by patients in Sweden and Italy with a view to providing a perspective on differences in treatment. Two consecutive samples of suicide attempters from Huddinge (n=97) and Padua (n=100) were studied in terms of sociodemographic characteristics, previous care, referral, medical and psychiatric care, hospitalization, aftercare, and short-term compliance. In Italian somatic management of acute suicidal crises, there are more physicians specializing in anesthesia or internal medicine working in ambulances and emergency wards, and there is a heavier emphasis on somatic care. Swedish management procedures seem to entail more medical examinations and biohumoral tests. Moreover, the procedures at the Swedish hospital give priority to early psychiatric intervention, and admission to psychiatric inpatient care is more frequent. However, it is not normal practice in emergency psychiatric care at either of the centers for specialists to serve in the immediate liaison consultation. There are differences in assessment and treatment between the two countries that may provide a perspective on their procedures, implying that current procedures for managing patients belonging to groups identified as "high-risk" in terms of suicide may be modified.

Blindness, fear of sight loss, and suicide

Numerous studies have examined the emotional impact exerted by sight loss. Research has tended to focus on clinical-diagnostic rather than therapeutic-preventive aspects. Blindness and sight restoration have been reported to induce both temporary and longer term psychopathology, usually followed by psychosocial readjustment. However, in some cases, readjustment may not occur and suicide may result. Together with an extensive review of available literature, the authors present cases taken from their psychological autopsy study database. When compared with a hearing-impaired control group, impaired sight alone can acutely affect otherwise psychologically healthy individuals. Ophthalmologists need to be aware of this problem and to develop closer collaboration with mental health professionals. Serious consideration of this problem and definition of clear guidelines may prevent suicidal behaviour.

Pharmacological and psychotherapeutic treatment of personality disorders in the elderly

Although estimates as to the incidence of personality disorder in the elderly remain controversial, it is well known that such a disorder is prevalently ego-syntonic and capable of interfering with the onset and treatment of other somatic and psychic pathologies, especially in later life, when individuals tend tobe particularly vulnerable. Misdiagnosis or failure to treat these disorders may greatly diminish the quality of life of older adults and their families. The aim of this work is to define the chief psychopharmacological and psychotherapeutic guidelines for treating personality disorders in the elderly. Pharmacologically, patients require treatment with molecules designed to rebalance neurotransmitter system alterations, which underlie the symptomatological picture. As regards psychotherapeutic treatment, although there are only a few validation studies, we believe that dialectical behavior therapy and interpersonal psychotherapy may constitute valid therapeutic approaches that meet both the needs and the individual characteristics of patients affected by personality disorder and those of elderly patients.

Peripheral lymphocyte subsets in human chronic pyelonephritis

Comparative study of peripheral blood lymphocyte surface markers in chronic pyelonephritis (CP) and chronic glomerulonephritis (GN) patients, and in normal controls showed no differences between controls and GN patients. In CP patients, a significant absolute increase in B cells, and an absolute decrease in T cells were observed as well as significantly lower and higher percentages of OKT4 and OKT8 cells, respectively, leading to a decrease in the OKT4/OKT8 ratio. Furthermore, the percentage of large granular cells was significantly higher in CP patients, while no differences in TIa cells emerged. The overall picture shown by the CP patients is compatible to a cell-mediated immune (CMI) response defect.

Dimethylformamide risk. An evaluation in the production of artificial organic leather

This study aimed to evaluate the exposure to DMF during the different stages in the production of synthetic polyurethanic leathers. Environmental surveys and biological surveillances were carried out in order to classify the working areas and the tasks of the employees as regards DMF-risk. Design improvements to reduce, as far as possible, environmental pollution are discussed.
