Synthesis of evidence for managing hypertensive disorders of pregnancy in low middle-income countries: a scoping review.

BACKGROUND AND OBJECTIVES: Hypertensive disorders of pregnancy (HDPs) remain one of the leading causes of maternal mortality globally, especially in Low- and middle-income countries (LMICs). To reduce the burden of associated morbidity and mortality, standardized prompt recognition, evaluation, and treatment have been proposed. Health disparities, barriers to access to healthcare, and shortage of resources influence these conditions. We aimed to synthesize the literature evidence for the management of HDPs in LMICs. METHODS: A scoping review was conducted in five databases (PubMed, Web of Science, Epistemonikos, Clinical Key and, Scielo) using MeSh terms, keywords, and Boolean connectors. We summarized the included studies according to the following categories: study design, objectives, settings, participant characteristics, eligibility criteria, interventions, assessed outcomes, and general findings. RESULTS: Six hundred fifty-one articles were retrieved from the literature search in five databases. Following the selection process, 65 articles met the predefined eligibility criteria. After performing a full-text analysis, 27 articles were included. Three themes were identified from the articles reviewed: prevention of HDPs, management of HDPs (antihypertensive and non-hypertensive management) and pregnancy monitoring and follow-up. The topics were approached from the perspective of LMICs. CONCLUSIONS: LMICs face substantial limitations and obstacles in the comprehensive management of HDPs. While management recommendations in most LMICs align with international guidelines, several factors, including limited access to crucial medications, unavailability of diagnostic tests, deficiencies in high-quality healthcare infrastructure, restrictions on continuing professional development, a shortage of trained personnel, community perceptions of preeclampsia, and outdated local clinical practice guidelines, impede the comprehensive management of patients. The development and implementation of protocols, standardized guides and intervention packages are a priority.

Clinical Characteristics and Outcomes of Patients With ANCA-Associated Vasculitides in a Colombian Hospital.

BACKGROUND/OBJECTIVE: Antineutrophil cytoplasmic antibody-associated vasculitides (AAVs) are uncommon systemic autoimmune diseases, of which few reports exist in Latin America. Our aim was to examine AAV evaluated in a high-complexity hospital in southwestern Colombia, with emphasis in severe forms. METHODS: A medical records review study of 67 patients was performed, and data were collected from electronic registries. Moderate and severe AAVs were defined as the presence of life-threatening complications, unfavorable Birmingham Vasculitis Activity Score outcomes, and hospitalization requirements at the time of diagnosis and by the last follow-up, between 2011 and 2019. Clinical manifestations, treatment, and outcomes were evaluated. The AAV subtypes were compared. RESULTS: A total of 67 cases were included. The majority were female (n = 44, 65.67%), and the median age was 52 (40-64) years. Granulomatosis with polyangiitis (GPA) was the most frequent with 42 patients (62.68%), followed by microscopic polyangiitis (MPA) and eosinophilic GPA, with 15 patients (22.38%) and 10 patients (14.92%), respectively. Forty-four patients (65.67%) presented pulmonary symptoms. The highest Birmingham Vasculitis Activity Score corresponded to MPA, with 21 (12-25) points. Fifteen patients (22.4%) were admitted to the intensive care unit throughout the course of the disease, of whom 10 had GPA. The longest stay and duration of mechanical ventilation were seen in MPA. The principal treatments were corticosteroids and cyclophosphamide, and the main outcome was end-stage renal disease. CONCLUSIONS: In this cohort of AAV, most of cases corresponded to GPA, and pulmonary manifestations were the most common. Microscopic polyangiitis was the more severe subtype as it showed worse impairment in clinical characteristics and intensive care unit requirements.
