Nursing diagnosis after hematopoietic stem cell transplant due to Fanconi anemia

ABSTRACT Objectives: to identify nursing diagnoses in patients who underwent hematopoietic stem-cell transplants due to Fanconi anemia, according to the NANDA-I taxonomy. Methods: exploratory study using a retrospective analysis of 85 records from patients who underwent hematopoietic stem-cell transplants due to Fanconi anemia, developed in a specialize transplant center in the South of Brazil. The results were analyzed using descriptive statistics. Results: 73 different diagnoses were found in 9 out of the 13 domains from the NANDA-I taxonomy. From these, 22 were in 50% or more of the patients investigated, and most of them are related to the domain Safety/Protection. Conclusions: it was possible to identify the nursing diagnosis in the patients who underwent hematopoietic stem cell transplants due to Fanconi anemia, contributing to design a plan for the care of these patients. The same was true for those with other syndromes of chromosomal instability that need to undergo this transplant.

Viral cultures, PCR Cycle threshold values and viral load estimation for COVID-19 infectious potential assessment in transplant patients: systematic review - Protocol Version 29 December 2021

This is the protocol for a systematic review focussing on people receiving solid organ or hematopoietic stem cell transplants. Our research questions are as follows: What is the relationship between serial PCR Ct value or other measures of viral burden, and the likelihood and duration of the presence of infectious virus from viral culture, among transplant recipients with SARS-CoV-2 infection? What is the influence of age, sex, underlying pathologies, degree of immunosuppression, vaccination status, COVID-19 symptoms and COVID-19 disease course on viral burden and the likelihood of presence of infectious SARS-CoV-2? We will include single studies reporting serial Cts from sequential rt-PCR testing or other measures of viral burden such as RNA gene copies of respiratory samples (from nasopharyngeal specimens) along with viral culture data on the same samples, from patients about to receive a transplant or who are post transplant with SARS-CoV-2 infection.

Analyses and Correlation of Pathologic and Ocular Cutaneous Changes in Murine Graft versus Host Disease

Graft versus host disease (GVHD) is initiated by donor allo-reactive T cells activated against recipient antigens. Chronic GVHD (cGVHD) is characterized by immune responses that may resemble autoimmune features present in the scleroderma and Sjogren’s syndrome. Unfortunately, ocular involvement occurs in approximately 60–90% of patients with cGVHD following allo-hematopoietic stem cell transplants (aHSCT). Ocular GVHD (oGVHD) may affect vision due to ocular adnexa damage leading to dry eye and keratopathy. Several other compartments including the skin are major targets of GVHD effector pathways. Using mouse aHSCT models, the objective was to characterize cGVHD associated alterations in the eye and skin to assess for correlations between these two organs. The examination of multiple models of MHC-matched and MHC-mismatched aHSCT identified a correlation between ocular and cutaneous involvement accompanying cGVHD. Studies detected a “positive” correlation, i.e., when cGVHD-induced ocular alterations were observed, cutaneous compartment alterations were also observed. When no or minimal ocular signs were detected, no or minimal skin changes were observed. In total, these findings suggest underlying cGVHD-inducing pathological immune mechanisms may be shared between the eye and skin. Based on the present observations, we posit that when skin involvement is present in aHSCT patients with cGVHD, the evaluation of the ocular surface by an ophthalmologist could potentially be of value.

Infectious Complications in Autoimmune Hemolytic Anemia

Autoimmune hemolytic anemia (AIHA) may be frequently challenged by infectious complications, mainly as a result of immunosuppressive treatments administered. Furthermore, infectious agents are known triggers of AIHA onset and relapse. Although being risk factors for mortality, infections are an underestimated issue in AIHA. This review will collect the available evidence on the frequency and type of infectious complications in AIHA, detailing the risk related to each treatment (i.e., steroids, rituximab, splenectomy, classic immunosuppressive agents, and new target drugs). Moreover, we will briefly discuss the infectious complications in AIHA secondary to other diseases that harbor an intrinsic infectious risk (e.g., primary immunodeficiencies, systemic autoimmune diseases, lymphoproliferative disorders, solid organ and hematopoietic stem cell transplants). Finally, viral and bacterial reactivations during immune suppressive therapies will be discussed, along with suggested screening and prophylactic strategies.
