Cytomegalovirus infection and disease in systemic lupus erythematosus patients at a high-complexity hospital in southwestern Colombia.

Cytomegalovirus (CMV) infection and disease is a condition usually described in immunocompromised patients, but among them, those with connective tissue diseases are poorly represented. Here we present the clinical, laboratory characteristics, management and outcomes of systemic lupus erythematosus (SLE) patients who presented with a CMV infection/disease to a high complexity hospital in southwestern Colombia between 2011 and 2020. 16 SLE patients were found to have a CMV infection.

Viperidae snake envenomation from a highly complex hospital in southwestern Colombia.

Background: Snake envenomation is a medical condition with high morbidity and mortality in southwestern Colombia.

Objectives: To describe the characteristics of the envenomation caused by Viperidae snakes view in a highly complex hospital in Southwestern Colombia.

Methods: A cross-sectional study was carried out.

Idiopathic gigantomastia exacerbated during pregnancy. Its relationship with autoimmunity: A case report.

Gigantomastia is a rare entity characterized by diffuse and excessive breast enlargement. It mainly occurs during puberty and pregnancy as a consequence of hormonal fluctuations. We report an unusual case of gigantomastia in a 29-year-old woman with a history of personal and familiar autoimmune phenomena.

Diagnostic Performance of Anti-dsDNA Tests by Indirect Immunofluorescence and Enzyme-linked Immunosorbent Assay in Patients with Systemic Lupus Erythematosus.

Background: Several laboratory techniques for anti double-stranded (ds) DNA detection in systemic lupus erythematosus (SLE) are available, with variable diagnostic performance. We aimed to evaluate anti-dsDNA's diagnostic performance by indirect immunofluorescence (IIF) and enzyme-linked immunosorbent assay (EIA).

Methods: We conducted a single-center retrospective (2015 to 2020) study.

B-cell activating factor (BAFF) and its receptors' expression in pediatric nephrotic syndrome is associated with worse prognosis.

Aim: Immune pathogenesis of nephrotic syndrome (NS) is not completely understood. We aimed to evaluate the expression of B-cell activating factor (BAFF) and its receptors in renal samples from pediatric NS patients and its relationship with renal function survival.

Materials And Methods: We conducted an ambispective study on 33 patients with pediatric NS.

Profile of specific and associated autoantibodies in patients with idiopathic inflammatory myopathies in a Colombian population.

Objectives: Idiopathic inflammatory myopathies (IIMs) are chronic, autoimmune diseases with several forms of presentation. Diagnosis is mostly clinical in our region. Our aim was to evaluate the autoantibody profile of patients with IIMs.

Lymphoid follicular hyperplasia in patients with systemic lupus erythematosus after multiple cycles of rituximab.

Rituximab is indicated in some patients with refractory systemic lupus erythematosus (SLE). Occasionally, this medication is required in chronic form to maintain control of the disease. We described two patients who developed lymphoid follicular hyperplasia (LFH) after multiple cycles of rituximab and evaluated the expression of B cell activating factor belonging to the tumor necrosis factor (TNF) family (BAFF) and its receptors [BAFF-receptor (BAFF-R) and B cell maturation antigen (BCMA)], as possible factors related to lymphoid node enlargement.

Description of the Etiologies, Clinical Characteristics, and Outcomes in Patients with Hyperferritinemia in a Colombian Tertiary Hospital.

Background: This study analyzes the clinical characteristics, outcomes, and conditions associated with hyperferritinemia (≥5000 ng/mL) in a high-complexity center in Colombia.

Methods: This retrospective and descriptive study was performed between 2011 and 2020, at the Fundación Valle del Lili, Cali, Colombia, by reviewing medical charts from patients who had serum ferritin measurements equal to or greater than 5000 ng/mL.

Results: We found 350 reports of ferritin values ≥5000 ng/mL, corresponding to 317 patients, with a median ferritin value of 8789 (6001-15 373)  ng/mL.

Association of Antiribosomal P Antibody with Neurological and Systemic Manifestations in Patients with Systemic Lupus Erythematosus in Southwestern Colombia.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by heterogeneous pathogenesis, various clinical manifestations, and a broad spectrum of autoantibodies which recognize different cellular components. This study examines the clinical significance and serological associations of serum antiribosomal P antibodies (anti-P) derived from SLE patients in a population from southwestern Colombia.

Methods: We performed a cross-sectional study of 66 SLE patients.

Lymphomagenesis predictors and related pathogenesis.

Sjögren's syndrome (SS) is a systemic autoimmune disease characterised by a wide range of clinical manifestations and complications, including B-cell lymphoma. This study aims to describe the predictors associated with lymphomagenesis in patients with Sjögren's syndrome, emphasising the pathophysiological bases that support this association. We performed a review of the literature published through a comprehensive search strategy in PubMed/MEDLINE, Scopus, and Web of science.

Reproducibility of minor salivary gland biopsy reports in Sjögren's syndrome and its correlation with disease biomarkers.

Introduction/objective: Sjögren's syndrome (SS) is a systemic autoimmune disease that is challenging to diagnose. Although minor salivary gland biopsy (MSGB) is a useful ancillary study, different factors make its interpretation difficult. Also, the significance of distinct histopathological findings is unknown.

Systemic lupus erythematosus in the intensive care unit: a systematic review.

Systemic lupus erythematosus (SLE) is an autoimmune disease with heterogeneous pathophysiologic mechanisms and diverse clinical manifestations. SLE is a frequent cause of intensive care unit (ICU) admissions. Multiple studies with controversial findings on the causes, evolution and outcomes of ICU-admitted patients with SLE have been published.

Clinical characterization, outcomes, and prognosis in patients with systemic lupus erythematosus admitted to the intensive care unit.

Objective: Systemic lupus erythematosus (SLE) is a clinically heterogeneous autoimmune disease, and in some conditions, admission to the intensive care unit (ICUs) is required. This study describes the clinical and prognostic factors in SLE patients admitted to the ICU.

Methods: We conducted a retrospective study that reviewed all clinical records of patients with SLE admitted to the ICU between 2011 and 2018.

Sjögren Syndrome in the Intensive Care Unit: An Observational Study.

Background/objective: Studies on the clinical characteristics, prognosis, and factors associated with mortality in patients with Sjögren syndrome (SS), particularly those in the intensive care unit (ICU), are limited. The present study aimed to describe clinical and immunological variables associated with mortality in patients with SS admitted to ICU at a single center in Cali, Colombia.

Methods: An observational, medical records review study was performed between 2011 and 2019 by reviewing the clinical records of patients with SS admitted to ICU at a high-complexity center.

Description of criteria for near miss in high-complexity obstetric population with sickle cell anemia: an observational study.

Sickle cell disease (SCD) is one of the most common monogenic diseases worldwide, affecting approximately 30 million people across the globe. It is one of the most common hemoglobinopathies affecting pregnancy, particularly in the black population. Pregnant women with SCD, in conjunction with the physiological changes of pregnancy, have an increased risk of developing severe maternal and fetal complications.
