Patient perceived quality of cirrhosis care- adjunctive nurse-based care versus standard medical care: a pragmatic multicentre randomised controlled study.

BACKGROUND: Cirrhosis treatment implies prevention and alleviation of serious disease events. Healthcare providers may, however, fail to meet patients' expectations of collaboration and specific needs of information and support. Individualised nursing care could meet patients' needs. The aim was thus to measure patient-perceived quality of care after adjunctive registered nurse-based intervention Quality Liver Nursing Care Model (QLiNCaM) compared with standard medical care. METHODS: This pragmatic multicentre study consecutively randomised patients to either adjunctive registered nurse-based care, or standard medical care for 24 months (ClinicalTrials.gov NCT02957253). Patients were allocated to either group at an equal ratio, at six Swedish outpatient clinics during 2016-2022. Using the questionnaire 'Quality of care from the patient's perspective', patients rated their perceived lack of quality for the adjunctive registered nurse-based intervention compared with the control group at 12 and 24 months, respectively. RESULTS: In total, 167 patients were recruited. Seven out of 22 items in the questionnaire supported the finding that 'lacking quality' decreased with adjunctive registered nurse-based care (p < 0.05) at 12 months follow-up; however, these differences could not be established at 24 months. CONCLUSION: Additional structured registered nurse-based visits in the cirrhosis outpatient team provided support for improved patient-perceived quality of care during the first 12 months. Registered nurses increase patient involvement and present easy access to cirrhosis outpatient care. Patients express appreciation for personalised information. This study reinforces registered nurses' role in the outpatient cirrhosis team, optimising patient care in compensated and decompensated cirrhosis.

Feeling safe or falling through the cracks-Patients' experiences of healthcare in cirrhosis illness: A qualitative study.

INTRODUCTION: Patients with cirrhosis have a long-lasting relationship with medical personnel. Hierarchy in the healthcare contacts and feeling stigmatised may affect the patient's interactions with these care providers. Despite healthcare professionals' awareness of patients' increased self-care needs, patients report getting insufficient information and support. The patients' expectations and experiences of interacting with healthcare professionals in cirrhosis care is hence a research area that needs further investigation. PURPOSE: To capture patients' descriptions of healthcare experiences in relation to cirrhosis illness. MATERIAL AND METHODS: Data comprise semi-structured interviews (N = 18) and open-ended questionnaire responses (N = 86) of patients with cirrhosis. Braun and Clarke's thematic analysis process was used, including both semantic and inductive elements. The study is reported following the COREQ guidelines. FINDINGS: The analysis resulted in two themes: 1) Struggle to be in a dialogue and 2) Being helped or harmed. Six sub-themes were identified concerning aspects of experiences within each theme during the analysis. These sub-themes included: 'getting information', 'being involved', 'being perceived as a person', 'enduring care', 'feeling lost in the healthcare organisation', and 'not being taken care of'. CONCLUSIONS: Patients with cirrhosis express concerns regarding where to turn in the continuum of cirrhosis care. They emphasise the importance of being involved in the dialogue with the healthcare professional, to be perceived as a person with a unique need to be informed. The healthcare organisation and continuity of care are either viewed as confusing or as helping to shape a safe and trustful contact, which was an important difference in feeling helped or harmed. Hence, patients wished for improved collaboration with healthcare professionals and to receive increased information about their disease. Person-centred communication in nurse-led clinics may increase patient satisfaction and prevent patients from falling through the cracks.

T cell perturbations persist for at least 6 months following hospitalization for COVID-19.

COVID-19 is being extensively studied, and much remains unknown regarding the long-term consequences of the disease on immune cells. The different arms of the immune system are interlinked, with humoral responses and the production of high-affinity antibodies being largely dependent on T cell immunity. Here, we longitudinally explored the effect COVID-19 has on T cell populations and the virus-specific T cells, as well as neutralizing antibody responses, for 6-7 months following hospitalization. The CD8+ TEMRA and exhausted CD57+ CD8+ T cells were markedly affected with elevated levels that lasted long into convalescence. Further, markers associated with T cell activation were upregulated at inclusion, and in the case of CD69+ CD4+ T cells this lasted all through the study duration. The levels of T cells expressing negative immune checkpoint molecules were increased in COVID-19 patients and sustained for a prolonged duration following recovery. Within 2-3 weeks after symptom onset, all COVID-19 patients developed anti-nucleocapsid IgG and spike-neutralizing IgG as well as SARS-CoV-2-specific T cell responses. In addition, we found alterations in follicular T helper (TFH) cell populations, such as enhanced TFH-TH2 following recovery from COVID-19. Our study revealed significant and long-term alterations in T cell populations and key events associated with COVID-19 pathogenesis.

SARS-CoV-2 Specific Antibody Response and T Cell-Immunity in Immunocompromised Patients up to Six Months Post COVID: A Pilot Study.

COVID-19 generates SARS-CoV-2-specific antibodies in immunocompetent individuals. However, in immunocompromised patients, the humoral immunity following infection may be impaired or absent. Recently, the assessment of cellular immunity to SARS-CoV-2, both following natural infection and vaccination, has contributed new knowledge regarding patients with low or no antibody responses. As part of a prospective cohort study which included hospitalized patients with COVID-19, we identified immunocompromised patients and compared them with age- and sex-matched immunocompetent patients regarding co-morbidities, biomarkers of COVID-19 and baseline viral load by real-time PCR in nasopharyngeal swabs. Spike and nucleocapsid antibody responses were analyzed at inclusion and after two weeks, six weeks and six months. Plasma immunoglobulin G (IgG) levels were quantified, lymphocyte phenotyping was performed, and SARS-CoV-2 specific CD4 and CD8 T cell responses after in vitro antigen stimulation were assessed at six months post infection. All patients showed IgG levels above or within reference limits. At six months, all patients had detectable SARS-CoV-2 anti-spike antibody levels. SARS-CoV-2 specific T cell responses were detected in 12 of 12 immunocompetent patients and in four of six immunocompromised patients. The magnitude of long-lived SARS-CoV-2 specific T cell responses were significantly correlated with the number of CD4 T cells and NK cells. Determining the durability of the humoral and cellular immune response against SARS-CoV-2 in immunocompromised individuals could be of importance by providing insights into the risk of re-infection and the need for vaccine boosters.

Specific T-cell responses for guiding treatment with convalescent plasma in severe COVID-19 and humoral immunodeficiency: a case report.

BACKGROUND: The immune response to SARS-CoV-2 virus, the cause of COVID-19, is complex. Antibody mediated responses are important for viral clearance but may also drive hyperinflammation in severe COVID-19. We present a case of an individual with a genetic inability to produce antibodies and severe COVID-19, receiving no other specific anti-viral treatment than convalescent COVID-19 plasma, illustrating that hyperinflammation can occur in the absence of a humoral anti-viral response. In addition, the case illustrates that the assessment of SARS-CoV-2 T cell responses can facilitate clinical decision making in patients with COVID-19 and weak or absent humoral immune responses. CASE PRESENTATION: A male with X-linked agammaglobulinemia on regular immunoglobulin replacement therapy, hospitalized for 35 days due to severe COVID-19. Systemic inflammatory parameters were highly elevated. After treatment with convalescent COVID-19 plasma he became afebrile and the fatigue diminished. He was discharged on day 42 and nasopharyngeal SARS-CoV-2 PCR eventually was negative on day 49. Evidence of SARS-CoV-2 specific T cells prior to administration of plasma therapy suggested that antibodies were crucial for viral clearance. Regular assessment showed robust and persistent SARS-CoV-2 specific T-cell responses after recovery suggested that prophylactic administration of convalescent COVID-19 plasma was unnecessary. CONCLUSION: Assessment of SARS-CoV-2T-cell responses can facilitate the clinical management of COVID-19 patients with humoral immunodeficiencies.

A backward-spinning star with two coplanar planets.

It is widely assumed that a star and its protoplanetary disk are initially aligned, with the stellar equator parallel to the disk plane. When observations reveal a misalignment between stellar rotation and the orbital motion of a planet, the usual interpretation is that the initial alignment was upset by gravitational perturbations that took place after planet formation. Most of the previously known misalignments involve isolated hot Jupiters, for which planet-planet scattering or secular effects from a wider-orbiting planet are the leading explanations. In theory, star/disk misalignments can result from turbulence during star formation or the gravitational torque of a wide-orbiting companion star, but no definite examples of this scenario are known. An ideal example would combine a coplanar system of multiple planets-ruling out planet-planet scattering or other disruptive postformation events-with a backward-rotating star, a condition that is easier to obtain from a primordial misalignment than from postformation perturbations. There are two previously known examples of a misaligned star in a coplanar multiplanet system, but in neither case has a suitable companion star been identified, nor is the stellar rotation known to be retrograde. Here, we show that the star K2-290 A is tilted by [Formula: see text] compared with the orbits of both of its known planets and has a wide-orbiting stellar companion that is capable of having tilted the protoplanetary disk. The system provides the clearest demonstration that stars and protoplanetary disks can become grossly misaligned due to the gravitational torque from a neighboring star.

Liver cirrhosis turns life into an unpredictable roller coaster: A qualitative interview study.

AIM: To explore how persons living with liver cirrhosis experience day-to-day life. BACKGROUND: Liver cirrhosis is the sixth most common cause of death among adults in Western countries. Persons with advanced liver cirrhosis report poor quality of life, in comparison with other chronic diseases. However, knowledge regarding day-to-day life during earlier stages of the disease is lacking. In other chronic diseases, the suffering process is well explored, while in liver cirrhosis, suffering is insufficiently investigated. DESIGN: An exploratory study, with a qualitative inductive interview approach. METHODS: A purposive maximum variation sample of 20 informants with liver cirrhosis aged 25-71, from two gastroenterology outpatient clinics in mid-Sweden, were interviewed from September 2016 to October 2017. Interview data were analysed inductively with qualitative content analysis. Reporting followed the COREQ guidelines. RESULTS: The experiences of day-to-day life living with liver cirrhosis comprised four sub-themes. Living with liver cirrhosis implied varying levels of deterioration, the most apparent being exhaustion or tiredness. The informants had to find ways of adapting to a new life situation. The insecurity of future health evoked existential reflections such as feeling emotionally and existentially distressed. Shame and guilt were reasons for feeling stigmatised. These sub-themes emerged into one overarching theme of meaning: life turns into an unpredictable roller coaster. This is based on experiences of liver cirrhosis as an unpredictable disease with fluctuating symptoms, worries and disease progression. CONCLUSION: Living with cirrhosis implies an unpredictable condition with a progressive, stigmatising disease. The fluctuating symptoms and deep concerns about future life pose an increased personal suffering. RELEVANCE TO CLINICAL PRACTICE: Within health care, knowledge of the person's experience is vital to enable and fulfil the person's healthcare needs. Clinical registered nurses need a person-centred approach to strengthen their patients to cope with their new life situation.

Treatment effects of fingolimod in multiple sclerosis: Selective changes in peripheral blood lymphocyte subsets.

BACKGROUND: Treatment with fingolimod reduces inflammation in multiple sclerosis (MS) by inhibiting lymphocyte egress from lymph nodes. We aimed to map, in detail, the alterations in peripheral blood lymphocyte subpopulations in relation to clinical outcome in MS patients treated with fingolimod. METHODS: Paired blood samples from relapsing-remitting MS patients (n = 19) were collected before and after one year of treatment with fingolimod (0.5 mg/day). Absolute counts and relative proportions of a broad set of T- B- and NK-cell subsets were analyzed by flow cytometry. Blood samples from 18 healthy controls were used for baseline comparisons. RESULTS: Treatment with fingolimod markedly decreased the absolute numbers of all major lymphocyte subsets, except for NK cells. The reduction was most pronounced within the T helper (Th) and B cell populations (p<0.001). By phenotyping differentiation status of T cells, dramatic reductions within the naïve and central memory (CM) cell populations were found (p<0.001), while a less pronounced reduction was observed among effector memory (EM) cells (p<0.001). The numbers of regulatory T cells (Tregs) were also decreased (p<0.001), but to a lesser extent than other T cell populations, resulting in a relative preservation of Tregs with a memory phenotype (p = 0.002). CONCLUSIONS: Our results confirm that fingolimod therapy markedly reduces lymphocyte counts in peripheral blood of MS patients. Subgroup analysis of T cells showed that naïve and CM Th cells were the most profoundly affected and that memory Tregs were relatively preserved.

Nurse-led clinic for patients with liver cirrhosis-effects on health-related quality of life: study protocol of a pragmatic multicentre randomised controlled trial.

INTRODUCTION: Liver cirrhosis affects health-related quality of life (HRQoL) even in its early stages. Morbidity is especially high when the disease decompensates and self-care actions become essential. Nurse involvement in secondary prevention in other chronic diseases has contributed to better symptom control, less need of inpatient care and improved HRQoL. In order to evaluate the impact of nurse involvement in the follow-up of patients with liver cirrhosis, we decided to compare structured nurse-led clinics, inspired by Dorothea Orem's nursing theory and motivational strategies, with a group of patients receiving standard care. The primary outcome is HRQoL and the secondary outcomes are quality of care, visits to outpatient clinics or hospitals, disease progress and health literacy. METHODS AND ANALYSIS: This is a pragmatic, multicentre randomised controlled study conducted at six Swedish hepatology departments. Eligible patients are adults with diagnosed cirrhosis of the liver (n=500). Participants are randomised into either an intervention with nurse-led follow-up group or into a standard of care group. Recruitment started in November 2016 and is expected to proceed until 2020. Primary outcomes are physical and mental HRQoL measured by RAND-36 at enrolment, after 1 and 2 years. ETHICS AND DISSEMINATION: The study is ethically approved by the Regional Ethical Review Board in Uppsala. The results shall be disseminated in international conferences and peer-reviewed articles. TRIAL REGISTRATION NUMBER: NCT02957253; Pre-results.

Regulatory T-cell Subpopulations in Severe or Early-onset Preeclampsia.

PROBLEM: A deficiency in regulatory T (Treg) cells causing reduced immune regulatory capacity has been proposed in preeclampsia. OBJECTIVE: Utilizing recent advances in flow cytometry phenotyping, we aimed to assess whether a deficiency of Treg subpopulations occurs in preeclampsia. METHOD OF STUDY: Six-color flow cytometry was used for Treg phenotyping in 18 preeclamptic women (one early-onset, one severe and 16 both), 20 women with normal pregnancy, and 20 non-pregnant controls. RESULTS: No differences were found in major Treg populations including CD127(low) CD25(+) /CD127(ow) FOXP3(+) , resting (FOXP3(dim) CD45RA(+) ), and activated (FOXP3(bright) CD45RA(-) ) Treg cells, whereas preeclamptic women showed increased CTLA-4(+) and CCR4(+) proportions within resting/activated Treg populations. Corticosteroid treatment prior to blood sampling (n = 10) affected the distribution of Treg populations. CONCLUSIONS: Although we found no major alterations in circulating Treg frequencies, differences in CTLA-4(+) and CCR4(+) frequencies suggest a migratory defect of Treg cells in preeclampsia. Corticosteroid treatment should be taken into account when evaluating Treg cells.

Long-lasting immune responses 4 years after GAD-alum treatment in children with type 1 diabetes.

A phase II clinical trial with glutamic acid decarboxylase (GAD) 65 formulated with aluminium hydroxide (GAD-alum) has shown efficacy in preserving residual insulin secretion in children and adolescents with recent-onset type 1 diabetes (T1D). We have performed a 4-year follow-up study of 59 of the original 70 patients to investigate long-term cellular and humoral immune responses after GAD-alum-treatment. Peripheral blood mononuclear cells (PBMC) were stimulated in vitro with GAD(65). Frequencies of naïve, central and effector memory CD4+ and CD8+ T cells were measured, together with cytokine secretion, proliferation, gene expression and serum GAD(65) autoantibody (GADA) levels. We here show that GAD-alum-treated patients display increased memory T-cell frequencies and prompt T-cell activation upon in vitro stimulation with GAD(65), but not with control antigens, compared with placebo subjects. GAD(65)-induced T-cell activation was accompanied by secretion of T helper (Th) 1, Th2 and T regulatory cytokines and by induction of T-cell inhibitory pathways. Moreover, post-treatment serum GADA titres remained persistently increased in the GAD-alum arm, but did not inhibit GAD(65) enzymatic activity. In conclusion, memory T- and B-cell responses persist 4 years after GAD-alum-treatment. In parallel to a GAD(65)-induced T-cell activation, our results show induction of T-cell inhibitory pathways important for regulating the GAD(65) immunity.

GAD-alum treatment induces GAD65-specific CD4+CD25highFOXP3+ cells in type 1 diabetic patients.

Type 1 diabetes results from autoimmune destruction of insulin producing pancreatic ß-cells. We have shown that treatment with alum-formulated glutamic acid decarboxylase 65 (GAD-alum) preserved residual insulin secretion and induced antigen-specific responses in children with recent onset type 1 diabetes. The aim of this study was to further investigate the immunomodulatory effect of GAD-alum, focusing on CD4(+)CD25(high) cells and their association to cytokine secretion. Samples obtained 21 and 30months after the initial injection of GAD-alum or placebo were included in the present study. GAD(65)-stimulation enhanced the percentage of CD4(+)CD25(high)FOXP3(+) cells, but reduced the percentage of CD4(+)CD25(+) cells, in samples from the GAD-alum treated group. Further, the GAD(65)-induced secretion of IL-5, -10, and -13 correlated with the expression of CD4(+)CD25(high)FOXP3(+) cells, but inversely with CD4(+)CD25(+) cells. These new data suggest that GAD-alum treatment induced GAD(65)-specific T cells with regulatory features.

Early induction of GAD(65)-reactive Th2 response in type 1 diabetic children treated with alum-formulated GAD(65).

BACKGROUND: We have previously shown that two injections of 20 µg alum-formulated glutamic acid decarboxylase 65 (GAD(65)) (GAD-alum; Diamyd(®)) in children with recent-onset type 1 diabetes lead to preservation of residual insulin secretion. In vitro cytokine production at the 15 months' follow-up indicated immunomodulation. In the present study, we took advantage of peripheral blood mononuclear cells, cryopreserved during early follow-ups, to investigate whether the immunomodulatory effect of GAD-alum was apparent earlier after treatment, preceding the changes previously reported at 15 months. METHODS: Peripheral blood mononuclear cells from 70 type 1 diabetic children, randomly assigned GAD-alum (n = 35) or placebo (n = 35), that had been frozen at baseline (n = 27) and after 1 (n = 58), 3 (n = 67) and 9 (n = 66) months, were stimulated in vitro with GAD(65), tyrosine phosphatase-like protein IA-2 peptide, insulin peptide, GAD-alum, alum formulation or phytohaemagglutinin. Interleukin (IL)-5, -6, -10, -12, -13, -17, tumour necrosis factor and interferon-γ were measured in cell supernatants and serum samples using Luminex. Expression of FOXP3 and transforming growth factor-ß was determined by real-time reverse transcription polymerase chain reaction. RESULTS: Already 1 month after the first injection, GAD(65)-induced IL-5 and IL-13 together with FOXP3 were enhanced in GAD-alum-treated patients compared to those with placebo. The in vitro response at 3 and 9 months was characterized by a broader range of cytokines in the treated group. Notably, only the T-helper 2-associated cytokines IL-5 and IL-13 together with FOXP3 increased continuously over time. CONCLUSIONS: Treatment with GAD-alum in type 1 diabetic children induced an early T-helper 2 immune enhanced response to GAD(65), followed by a wider spectrum of cytokines at 3 and 9 months.

GAD treatment and insulin secretion in recent-onset type 1 diabetes.

BACKGROUND: The 65-kD isoform of glutamic acid decarboxylase (GAD) is a major autoantigen in patients with type 1 diabetes mellitus. This trial assessed the ability of alum-formulated GAD (GAD-alum) to reverse recent-onset type 1 diabetes in patients 10 to 18 years of age. METHODS: We randomly assigned 70 patients with type 1 diabetes who had fasting C-peptide levels above 0.1 nmol per liter (0.3 ng per milliliter) and GAD autoantibodies, recruited within 18 months after receiving the diagnosis of diabetes, to receive subcutaneous injections of 20 microg of GAD-alum (35 patients) or placebo (alum alone, 35 patients) on study days 1 and 30. At day 1 and months 3, 9, 15, 21, and 30, patients underwent a mixed-meal tolerance test to stimulate residual insulin secretion (measured as the C-peptide level). The effect of GAD-alum on the immune system was also studied. RESULTS: Insulin secretion gradually decreased in both study groups. The study treatment had no significant effect on change in fasting C-peptide level after 15 months (the primary end point). Fasting C-peptide levels declined from baseline levels significantly less over 30 months in the GAD-alum group than in the placebo group (-0.21 vs. -0.27 nmol per liter [-0.62 vs. -0.81 ng per milliliter], P=0.045), as did stimulated secretion measured as the area under the curve (-0.72 vs. -1.02 nmol per liter per 2 hours [-2.20 vs. -3.08 ng per milliliter per 2 hours], P=0.04). No protective effect was seen in patients treated 6 months or more after receiving the diagnosis. Adverse events appeared to be mild and similar in frequency between the two groups. The GAD-alum treatment induced a GAD-specific immune response. CONCLUSIONS: GAD-alum may contribute to the preservation of residual insulin secretion in patients with recent-onset type 1 diabetes, although it did not change the insulin requirement.
