- Changes in their daily lives that patients endure because of hemodialysis are major and also essential so they can stay alive. The aim of this study was to describe changes in life for patients with renal failure undergoing hemodialysis. The study has a qualitative descriptive approach with a qualitative content analysis based on in-depth interviews with patients undergoing hemodialysis. Results show that life in hemodialysis is experienced as a transition from liberty to captivity, adjusting to the new life, and the new life moving towards reconciliation. This study shows that support towards reconciliation is crucial for patient health.

- Background: Soluble P-selectin (sP-selectin) and high-sensitivity C-reactive protein (hsCRP) have previously been associated with hypertension, but the relation with out-of-office blood pressure (BP) and coronary artery calcification score is unknown. We aimed to examine the relationship between sP-selectin, hsCRP and home BP, as well as coronary artery calcification score and carotid artery plaques.Methods: In the Swedish CArdioPulmonary bioImage Study (SCAPIS), 5057 randomly selected participants were evaluated with office and home BP using the semi-automatic Omron M10-IT device. For this cross-sectional study, participants with sP-selectin <4 standard deviations above mean and hsCRP <5 mg/l, representing low-grade inflammation, were included. Using generalized linear models, these inflammatory markers were evaluated in relation to BP classifications, as well as coronary artery calcification score and carotid artery plaques.Results: Of participants, 4548 were included in the analyses. The median age was 57.2 (53.4–61.2) years, and 775 (17.0%) reported taking medication for hypertension. Participants in the highest quartile of sP-selectin [odds ratio (OR) 1.67, 95% confidence interval (CI) 1.40–1.98, P < 0.001] and hsCRP [OR 2.25, (95% CI 1.89–2.60), P < 0.001] were more likely to have sustained hypertension. Participants in the highest quartile of hsCRP were also more likely to have masked hypertension, OR (95% CI) 2.31 (1.72–3.10), P < 0.001 and carotid artery plaques, OR (95% CI) 1.21 (1.05–1.38), P = 0.007.Conclusion: Increased sP-selectin and hsCRP were independently associated with sustained hypertension. These findings indicate an association between hypertension and platelet activity, as expressed by sP-selectin.

Cytomegalovirus seropositivity is a major determinant of CD28null T cell expansion in patients with coronary artery disease
- 2014

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objective: Accumulation of CD4+28null cells, with a proinflammatory and senescent phenotype, has been associated with unstable conditions of coronary artery disease (CAD). Human cytomegalovirus (HCMV) is known to exert profound effects on T cells, including loss of CD28. Here, we longitudinally assessed the proportions of CD28null and CD28nullCD57+ cells in CD4+ and CD8+ T cell populations of patients with CAD and related the findings to HCMV seropositivity.Methods: HCMV antibody levels and expression of CD28 and CD57 on CD4+ and CD8+ T cells were analysed in 31 patients with acute coronary syndrome (ACS), 34 patients with stable angina (SA) and 37 healthy controls. Samples were taken prior to 34 coronary angiography and after 3 and 12 months. In a subsample, HCMV-specific IFN-γ and TNF production was assessed ex vivo.Results: Increased proportions of CD4+CD28null, but not CD8+CD28null cells, were significantly associated with presence of CAD. Significant increases in CD28null 37 and CD28nullCD57+ cells occurred within CD4+ and CD8+ T cell compartments in both ACS and SA patients during 12-month follow-up. HCMV was the major determinant of CD28null and CD28nullCD57+ T cell levels in both patients and controls (p <0.001). There were no obvious signs of CMV reactivation in patients.Conclusion: HCMV was a major determinant of the presence of CD28null and CD28nullCD57+ T cells in patients with CAD, independent of clinical stage. Findings also indicate that HCMV might have a large impact on the T cell aging process that occurred in patients after a cardiac event.

Lymphocyte Subpopulations in Lymph Nodes and Peripheral Blood: A Comparison between Patients with Stable Angina and Acute Coronary Syndrome

- Objective: Atherosclerosis is characterized by a chronic inflammatory response involving activated T cells and impairment of natural killer (NK) cells. An increased T cell activity has been associated with plaque instability and risk of acute cardiac events. Lymphocyte analyses in blood are widely used to evaluate the immune status. However, peripheral blood contains only a minor proportion of lymphocytes. In this study, we hypothesized that thoracic lymph nodes from patients with stable angina (SA) and acute coronary syndrome (ACS) might add information to peripheral blood analyses. less thanbrgreater than less thanbrgreater thanMethods: Peripheral blood and lymph nodes were collected during coronary by-pass surgery in 13 patients with SA and 13 patients with ACS. Lymphocyte subpopulations were assessed by flow cytometry using antibodies against CD3, CD4, CD8, CD19, CD16/56, CD25, Foxp3, CD69, HLA-DR, IL-18 receptor (R) and CCR4. less thanbrgreater than less thanbrgreater thanResults: Lymph nodes revealed a lymphocyte subpopulation profile substantially differing from that in blood including a higher proportion of B cells, lower proportions of CD8(+) T cells and NK cells and a 2-fold higher CD4/CD8 ratio. CD4(+)CD69(+) cells as well as Foxp3(+) regulatory T cells were markedly enriched in lymph nodes (p andlt; 0.001) while T helper 1-like (CD4(+)IL-18R(+)) cells were more frequent in blood (p andlt; 0.001). The only significant differences between ACS and SA patients involved NK cells that were reduced in the ACS group. However, despite being reduced, the NK cell fraction in ACS patients contained a significantly higher proportion of IL-18R(+) cells compared with SA patients (p andlt; 0.05). less thanbrgreater than less thanbrgreater thanConclusion: There were several differences in lymphocyte subpopulations between blood and lymph nodes. However, the lymphocyte perturbations in peripheral blood of ACS patients compared with SA patients were not mirrored in lymph nodes. The findings indicate that lymph node analyses in multivessel coronary artery disease may not reveal any major changes in the immune response that are not detectable in blood.

- Although reduced natural killer (NK) cell levels have been reported consistently in patients with coronary artery disease (CAD), the clinical significance and persistence of this immune perturbation is not clarified. In this study we characterized the NK cell deficit further by determining (i) differentiation surface markers and cytokine profile of NK cell subsets and (ii) ability to reconstitute NK cell levels over time. Flow cytometry was used to analyse NK cell subsets and the intracellular cytokine profile in 31 patients with non-ST elevation myocardial infarction (non-STEMI), 34 patients with stable angina (SA) and 37 healthy controls. In blood collected prior to coronary angiography, the proportions of NK cells were reduced significantly in non-STEMI and SA patients compared with controls, whereas NK cell subset analyses or cytokine profile measurements did not reveal any differences across groups. During a 12-month follow-up, the proportions of NK cells increased, although not in all patients. Failure to reconstitute NK cell levels was associated with several components of metabolic syndrome. Moreover, interleukin (IL)-6 levels remained high in patients with sustained NK cell deficit, whereas a decline in IL-6 (P < 0·001) was seen in patients with a pronounced increase in NK cells. In conclusion, we found no evidence that reduction of NK cells in CAD patients was associated with aberrations in NK cell phenotype at any clinical stage of the disease. Conversely, failure to reconstitute NK cell levels was associated with a persistent low-grade inflammation, suggesting a protective role of NK cells in CAD.
