Epidemiology, Management, and Outcome of Atypical Hemolytic Uremic Syndrome in an Omani Cohort

Objectives

Atypical hemolytic uremic syndrome (aHUS) is a rare, life-threatening disease of chronic uncontrolled complement pathway activation that leads to thrombotic-microangiopathy, along with severe organ damage, including end-stage kidney disease. This study aimed to evaluate the epidemiology, management, and outcome of aHUS in an Omani population.

Methods

This retrospective descriptive cohort study assessed all cases of aHUS diagnosed and followed up at two tertiary care centers in Oman from January 2008 to December 2019, based on clinical features, complement pathway assays, histopathological, and genetic testing.

Results

The study accrued 19 patients who fulfilled the inclusion criteria, of whom 11 (57.9%) were male. The participants' median age was 25.0 years (range = 0.1-69.0). Most (15; 78.9%) patients presented in the acute phase of the disease. The triad of hemolytic anemia, acute kidney injury, and thrombocytopenia was present in all patients. A trigger factor (e.g., infection) was identified in 68.4% of cases. Of the 14 (73.7%) patients who underwent kidney biopsy, 10 (71.4%) were found to have aHUS in native kidneys and three in grafted kidneys. Of the 11 (57.9%) patients who underwent genetic analysis, five (45.5%) were found to have a known pathogenic variant in their aHUS susceptibility genes. Plasma exchange followed by eculizumab was the treatment method in 11 (57.9%) cases. Complete renal recovery was achieved in seven (36.8%) patients, while four (21.1%) passed away during the study period.

Conclusions

The wide spectrum and multiple expressions of aHUS make it a challenge to diagnose and consequently may delay the commencement of the targeted treatment. Eculizumab is considered the first-line therapy and should be commenced as early as possible.

Advanced practice nursing roles in Arab countries in the Eastern Mediterranean region: a scoping review

OBJECTIVE

The objectives of this review were to map and summarize evidence regarding advanced practice nursing roles in Arab countries located in the Eastern Mediterranean region.

INTRODUCTION

Many countries have reported an increase in the number and types of advanced practice nursing roles as research demonstrating their positive impact on patient and health system outcomes continues to accumulate. There is international evidence that the achievement of these outcomes depends on the effective implementation of advanced practice nursing roles at the organizational and country levels. A comprehensive review of the status of advanced practice nursing role implementation in Arab countries in the Eastern Mediterranean region has not been conducted.

INCLUSION CRITERIA

Eligible studies included advanced practice nursing roles (including, but not limited to, nurse practitioners and clinical nurse specialists) in Arab countries in the Eastern Mediterranean region. Studies were considered if they focused on role development, titles, entry-level education, regulation and scope of practice, and facilitators and barriers to role implementation.

METHODS

A comprehensive systematic search was completed for both published and non-published literature. The databases searched included CINAHL, PubMed, PsycINFO, Embase, Nursing and Allied Health Database, and Scopus. Gray literature was searched using websites such as Google Scholar, ProQuest Dissertations and Theses, International Council of Nurses, World Health Organization regional office for the Eastern Mediterranean region, and websites of nursing associations and Ministries of Health in Arab countries. The search included literature published in Arabic and English from the inception of the databases to August 2020.

RESULTS

A total of 35 articles were included, the majority (n = 24) of which were published from 2010 onward. Ten of the included studies were empirical research papers that used qualitative and quantitative research designs. Advanced practice nursing role development is still in its infancy in most of the Arab countries in the Eastern Mediterranean region and can be described as slowly and steadily evolving. The main driving forces for the implementation of the roles in this region included a shortage of physicians both in number and specialties, the emergence of chronic diseases due to lifestyle changes, the desire to have more cost-effective primary care, and to advance nursing as a profession. Clinical nurse specialists and nurse practitioners are the most common titles for the advanced nursing roles practiced in the region. Some advanced practice nursing roles stipulated a master's degree as a minimum requirement, while others required a 12-month in-house training program. Oman is the only Arab country that authorizes nurse practitioners to prescribe pre-set medications. The common barriers to advanced practice nursing role implementation included a lack of recognition of roles at national levels, role ambiguity, lack of clear scope of practice, resistance from male physicians, low involvement of nurses in policy-making, and low status of nursing as a profession.

CONCLUSION

The successful implementation and sustainment of advanced practice nursing roles in Arab countries in the Eastern Mediterranean region requires foundational work, including development of definitions, educational standards, regulations, and a clear scope of practice.
