Article Synopsis
  • Lupus nephritis is an immune-mediated kidney disease related to systemic lupus erythematosus (SLE), showing diverse effects across different populations, particularly in the Colombian Caribbean.
  • In a study of 401 SLE patients, most were women with a median age of 42, 90% had proliferative kidney lesions, and over half did not respond to treatment, highlighting challenges in management.
  • Key factors linked to poor outcomes included high initial proteinuria levels and elevated serum creatinine, emphasizing the need for personalized treatment strategies to enhance patient care and survival.

Article Synopsis
  • * A cross-sectional study involving 42 patients with biopsy-proven LN used tools like the Lupus Quality of Life (LupusQoL) and the Compliance Questionnaire in Rheumatology 19 (CQR19) to evaluate HRQoL and medication adherence, defining non-adherence as taking less than 80% of their prescribed medication.
  • * Results showed that 60% of patients were

Objective: This study aimed to identify by in silico methods tropomyosin consensus B and T epitopes of shrimp species, house dust mites, insects, and nematodes associated with allergic diseases in tropical countries.

Methods: In silico analysis included tropomyosin from mites (Der p 10, Der f 10, Blo t 10), insects (Aed a 10, Per a 7, Bla g 7), shrimp (Lit v 1, Pen m 1, Pen a 1), and nematode (Asc l 3) all sequences were taken from the UniProt database. Linear IgE epitopes were predicted with AlgPred 2.

Objective: To evaluate the IgE reactivity of sera in patients suffering from type 1 diabetes (T1D), lupus nephritis (LN) and juvenile idiopathic arthritis (JIA) against a molecule constructed from T epitopes of allergens.

Methods: We designed and expressed a synthetic multi-epítope protein named MP1 from A. lumbricoides and house dust mites allergens.

Pregnancy-associated atypical hemolytic uremic syndrome (P-aHUS) is a rare condition characterized by microangiopathic hemolytic anemia and kidney injury from thrombotic microangiopathy. P-aHUS occurs in approximately 1 in 25,000 pregnancies and is strongly related to complement dysregulation and pregnancy-related disorders, such as preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, low platelet (HELLP) syndrome, resulting in adverse perinatal and fetal outcomes. Complement dysregulation in P-aHUS is commonly attributed to genetic mutations or autoantibodies affecting complement factors, including , , and We present a case of a 25-year-old primigravida who experienced severe preeclampsia and HELLP syndrome followed by the development of complicated P-aHUS during the early postpartum period.

Atypical hemolytic uremic syndrome (aHUS) is a rare complement-mediated kidney disease with genetic predisposition and represents up to 10% of pediatric hemolytic uremic syndrome (HUS) cases. Few studies have evaluated aHUS in Latin American population. We studied a Colombian pediatric cohort to delineate disease presentation and outcomes.

Introduction: Sickle cell anemia (SCA) is a hemoglobinopathy presenting severe endothelial damage associated with increased prevalence of hypertension (HTN). Few studies have used ambulatory blood pressure monitoring (ABPM) in pediatric patients with SCA. The aim of this study was to characterize the ABPM profile in children with SCA.

Introduction: Chronic spontaneous urticaria (CSU) is an inflammatory skin disease related to poor quality of life. Previous studies have found that vitamin D deficiency and vitamin D receptor () , and gene single-nucleotide polymorphisms (SNPs) influence immune response and susceptibility to skin disorders.

Aim: To explore the role of SNPs, and the association of vitamin D serum levels in a sample of Colombian Caribbean CSU patients.

Our study aimed to describe the glomerular diseases, both primary glomerular disease (PGD) and secondary glomerular disease (SGD) in the Colombian Caribbean based on the first regional Colombian Nephropathy Registry (NEFRORED®). A descriptive and retrospective study of adult patients with glomerular diseases from the Colombian Caribbean region was made. All diagnoses by renal biopsy with light microscopy and immunofluorescence obtained between January 2008 and June 2018 were recorded.

Introduction: Atypical hemolytic uremic syndrome (aHUS) is a rare and genetically mediated systemic disease most often caused by uncontrolled and chronic complement activation that leads to systemic thrombotic microangiopathy, renal and extra-renal damage.

Materials And Methods: This is descriptive, retrospective and multicenter study, which reports demographic, clinical, laboratory, and genetic characteristics, as well as their treatment response and outcome of 20 aHUS patients diagnosed between 2014 and 2018.

Results: Most patients were female adults (75%) and 30% were associated to pregnancy/postpartum, 15% to autoimmune disease, and 65% to infections.
