Treatment patterns of antidiabetic and kidney protective therapies among patients with type 2 diabetes mellitus and chronic kidney disease in Colombia. The KDICO descriptive study.

BACKGROUND: Type 2 diabetes mellitus is one of the most common causes of chronic kidney disease (CKD) worldwide and prevalence of 1.75 per 100 inhabitants in Colombia. The aim of this study was to describe the treatment patterns of a group of patients with type 2 diabetes mellitus and CKD in an outpatient setting from Colombia. METHODS: A cross-sectional study in adult patients with type 2 diabetes mellitus and CKD identified in the Audifarma S.A. administrative healthcare database between April 2019 and March 2020 was performed. Sociodemographic, clinical and pharmacological variables were considered and analyzed. RESULTS: A total of 14,722 patients with type 2 diabetes mellitus and CKD were identified, predominantly male (51%), with a mean age of 74.7 years. The most common treatment patterns of type 2 diabetes mellitus included the use of metformin monotherapy (20.5%), followed by the combination of metformin + dipeptidyl peptidase-4 inhibitor (13.4%). Regarding the use of drugs with nephroprotective properties, the most prescribed treatments were angiotensin receptor blockers (67.2%), angiotensin converting enzyme inhibitors (15.8%), sodium glucose cotransporter 2 inhibitors (SGLT2i) (17.0%) and glucagon-like peptide-1 analogs (GLP1a) (5.2%). CONCLUSION: In Colombia, the majority of patients with type 2 diabetes mellitus and CKD identified in this study were treated with antidiabetic and protective medications to ensure adequate metabolic, cardiovascular, and renal control. The management of type 2 diabetes mellitus and CKD may be improved if the beneficial properties of new groups of antidiabetics (SGLT2i, GLP1a), as well as novel mineralocorticoid receptor antagonists, are considered.

Quality of life, self-reported outcomes and impact of education among people with moderate and severe hemophilia A: An integrated perspective from a Latin American country.

Collecting and interpreting self-reported outcomes among people with hemophilia A supports the understanding of the burden of the disease and its treatment to improve holistic care. However, in Colombia, this information is limited. Therefore, this study aimed to describe the knowledge, perception and burden of hemophilia A from the patients' perspective. A cross-sectional study was conducted in the context of a hemophilia educational bootcamp held from November 29th to December 1st, 2019, in Medellin, Colombia. The bootcamp was organized by a hemophilia patient association responsible for contacting and inviting patients with hemophilia A (PwHA). Information on patients' health beliefs, treatment experiences, and health-related quality of life (HRQoL) was obtained through focus groups, individual interviews and the Patient Reported Outcomes, Burdens and Experiences (PROBE) questionnaire. A total of 25 moderate or severe PwHA were enrolled in this study and completed the PROBE questionnaire. Acute pain was the most frequently reported symptom, with 88% of the patients reporting the use of pain medication. Difficulty with activities of daily living was reported by 48%. Furthermore, 52% reported having more than 2 spontaneous bleeding events in the last year. Treatment was administered at home for 72% of patients, with regular prophylaxis as the most common treatment regimen. In terms of overall HRQoL, the median EQ-5D VAS score was 80 (IQR: 50-100). PwHA in Colombia still suffer from disease complications related to bleeding events, pain and disability that affect their HRQoL, which highlights the need to develop patient-centered initiatives to improve the wellness of this population.

Uso ambulatorio de cefalosporinas en una población colombiana: estudio de prescripción-indicación / Outpatient cephalosporin use in a Colombian population: prescription-indication study

INTRODUCCIÓN: El uso indebido de cefalosporinas puede provocar resistencia de las bacterias. OBJETIVO: Determinar el perfil de prescripción e indicación de cefalosporinas en un grupo de pacientes afiliados al Sistema de Salud de Colombia. MÉTODOS: Estudio transversal. A partir de una base de datos poblacional se obtuvo una muestra aleatoria de pacientes atendidos en consulta ambulatoria para identificar las indicaciones de cefalosporinas en registros clínicos. Se evaluaron variables farmacológicas relacionadas con formulación no indicada según guías de práctica clínica. RESULTADOS: En 381 pacientes, con edad media 41,2 ± 15,4 años, el 61,4% (n = 234) eran mujeres. Cefalexina fue la más utilizada (n=318; 83,5%), con duración media del tratamiento de 7,3 ± 3,2 días, seguida de cefradina (n = 43, 11,3%) y ceftriaxona (n = 20, 5,2%). Se prescribieron para infecciones de piel y tejidos blandos (n = 177; 46,4%, de las cuales 47,5% eran purulentas), del tracto urinario (n = 70; 18,4%), de vías respiratorias superiores (n = 57; 15,0%), e infecciones de transmisión sexual (n = 21; 5,5%). Estaban indicadas en 169 pacientes (44,4%), pero sólo 103 (60,9%) tenían prescripciones que cumplían las recomendaciones de dosificación. CONCLUSIONES: Más de la mitad de pacientes prescritos con cefalosporinas en un contexto ambulatorio tenían prescripciones consideradas no indicadas, en particular por su uso en infecciones de piel y tejidos blandos purulentas.

BACKGROUND: Misuse of cephalosporins can lead to bacterial resistance. Aim: To determine the prescription profile and indication of cephalosporins in the patients affiliated to the Colombian Health System. METHODS: Cross-sectional study. From a population database, a random sample of patients treated in an outpatient consultation was obtained, to identify the indications of the prescribed cephalosporins in their clinical record. Pharmacological variables, and those related to non-indicated formulations were evaluated according to the clinical practice guidelines. RESULTS: In 381 patients, the mean age was 41.2 ± 15.4 years, and 61.4% (n = 234) were women. Cefalexin was the most widely used (n=318; 83.5%), with a mean duration of treatment of 7.3 ± 3.2 days; followed by cefradine (n = 43; 11.3%), and ceftriaxone (n = 20; 5.2%). The most common uses were for skin and soft tissue infections (n = 177; 46.4% of which 47.5% were purulent), urinary tract infections (n = 70; 18.4%), upper respiratory airway infections (n = 57; 15.0%) and sexually transmitted diseases (n = 21; 5.5%). The use was considered indicated in 169 patients (44.4%), but only 103 (60.9%) had prescriptions that met the dosage recommendations from the clinical practice guidelines. CONCLUSIONS: More than half of the patients prescribed with cephalosporins in the outpatient setting had prescriptions considered not indicated, particularly for their use in purulent skin and soft tissue infections.

Availability of secondary healthcare data for conducting pharmacoepidemiology studies in Colombia: A systematic review.

Real-world evidence (RWE) is emerging as a fundamental component of the post-marketing evaluation of medicinal products. Even though the focus on RWE studies has increased in Colombia, the availability of secondary data sources to perform this type of research is not well documented. Thus, we aimed at identifying and characterizing secondary data sources available in Colombia. We performed a systematic literature review on PubMed, EMBASE, and VHL using a combination of controlled vocabulary and keywords for the concepts of electronic health records, epidemiologic studies and Colombia. A total of 323 publications were included. These comprised 123 identified secondary data sources including pharmacy dispensing databases, government datasets, disease registries, insurance databases, and electronic heath records, among others. These data sources were mostly used for cross-sectional studies focused on disease epidemiology in a specific population. Almost all databases (95%) contained demographic information, followed by pharmacological treatment (44%) and diagnostic tests (39%). Even though the database owner was identifiable in 94%, access information was only available in 44% of the articles. Only a pharmacy-dispensing database, local cancer registries, and government databases included a description regarding the quality of the information available. The diversity of databases identified shows that Colombia has a high potential to continue enhancing its RWE strategy. Greater efforts are required to improve data quality and accessibility. The linkage between databases will expand data pooling and integration to boost the translational potential of RWE.

Nuevos enfoques farmacológicos en el manejo de la angina de pecho estable / New pharmacological approaches in the management of stable angina

RESUMEN En años recientes han sido introducidos nuevos antianginosos al mercado con mecanismos de acción novedosos, complementarios a los del arsenal farmacoterapéutico existente. Aunque el tratamiento de primera línea continúan siendo los betabloqueadores, antagonistas de canales de calcio y nitratos, el descubrimientos de nuevos aspectos fisiopatológicos de la enfermedad permitieron el desarrollo de blancos terapéuticos innovadores a nivel celular y molecular. El nicorandil, la trimetazidina, la ivabradina y la ranolazina se consideran nuevos fármacos antianginosos y constituyen la segunda línea de tratamiento de la angina de pecho estable; están indicados en pacientes que persisten sintomáticos a pesar del manejo de primera línea o en aquellos que presentan intolerancia o contraindicación a los betabloqueadores o antagonistas de canales de calcio. La trimetazidina, a través de su mecanismo de acción metabólico, mejora la tolerancia al ejercicio y puede ser útil en pacientes con falla cardíaca y contraindicación al uso de digitales; la ivabradina tiene un efecto cronotrópico negativo sin afectar el inotropismo ni la tensión arterial por lo que se puede usar en pacientes con taquiarritmias o falla cardíaca concomitante; en contraste, la ranolazina no afecta el cronotropismo por lo que se usa en pacientes con bradiarritmias aunque puede generar prolongación del intervalo QTc. La elección de alguno de estos medicamentos antianginosos de primera o segunda línea debe ser individualizado para cada paciente y se basa en las comorbilidades, contraindicaciones y preferencias del paciente.

ABSTRACT In recent years, new antianginal agents with novel mechanisms of action have been launched to the market, as a complement to the existing therapeutic arsenal. Even though the beta-blockers, calcium channel blockers and nitrates continue to be the first line of treatment, recent discoveries of pathophysiological aspects of the disease led to the development of innovative therapeutic targets on both cellular and molecular level. Nicorandil, trimetazidine, ivabradine and ranolazine are novel antianginal drugs and constitute the second line of treatment of stable angina; these drugs are indicated for those patients who persist symptomatic despite treatment with first line agents or in those with contraindication or intolerance to beta-blockers o calcium channel blockers. Trimetazidine, through its metabolic mechanism of action, improves exercise tolerance and might be useful in patients with concomitant heart failure and contraindication to digitalis; ivabradine can be used in patients with concomitant tachyarrhythmias due to its negative chronotropic effect without affecting inotropism or blood pressure; in contrast, ranolazine doesn't affect chronotropism and can be used in patients with bradyarrhythmias, however, it might cause prolongation of the QTc interval. The choice of treatment with either of the first line or second line antianginal agents must be individualized for each patient and based on comorbidities, contraindications and patient's preference.

Autoimmune thyroid disease in Colombian patients with systemic lupus erythematosus.

OBJECTIVES: To determine the prevalence and the predictive factors of autoimmune hypothyroidism (AH) within a systemic lupus erythematosus (SLE) cohort and to analyse the current information concerning the prevalence and impact of autoimmune thyroid disease (AITD) and thyroid autoimmunity in patients with SLE. METHODS: A total of 376 patients with SLE were assessed for the presence of the following: (i) confirmed AH, (ii) positive thy-roperoxidase/thyroglobulin antibodies [TPOAb/TgAb] without hypothyroidism, (iii) nonautoimmune hypothyroidism and (iv) SLE patients with neither. Multivariate analysis and a classification and regression tree model were used to analyse data. The current information was discussed through a systematic literature review (SLR). RESULTS: In our cohort, the prevalence of confirmed AH was 12%. However, in euthyroid patients with SLE, TPOAb and TgAb were observed in 21% and 10%, respectively. Patients with confirmed AH were significantly older and had later age at onset of the disease. Smoking (adjusted odds ratio (AOR) 6·93, 95% CI 1·98-28·54, P = 0·004), Sjögren's Syndrome (SS) (AOR 23·2, 95% CI 1·89-359·53, P = 0·015) and positivity for anticyclic citrullinated peptide (anti-CCP) (AOR 10·35, 95% CI 1·04-121·26, P = 0·047) were associated with AH-SLE, regardless of gender and duration of the disease. Smoking and SS were confirmed as predictors of AH-SLE. In the SLR, the prevalence of AITD ranged from 1% to 60%. The factors associated with this polyautoimmunity were female gender, older age, smoking, certain autoantibodies, SS, and cutaneous and articular involvement. CONCLUSIONS: AITD is frequent in SLE and does not affect the severity of SLE. Identified risk factors will assist clinicians in the search for AITD. Our results encourage smoke-free policies in patients with SLE.

The coexistence of antiphospholipid syndrome and systemic lupus erythematosus in Colombians.

OBJECTIVES: To examine the prevalence and associated factors related to the coexistence of antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) in a cohort of Colombian patients with SLE, and to discuss the coexistence of APS with other autoimmune diseases (ADs). METHOD: A total of 376 patients with SLE were assessed for the presence of the following: 1) confirmed APS; 2) positivity for antiphospholipid (aPL) antibodies without a prior thromboembolic nor obstetric event; and 3) SLE patients without APS nor positivity for aPL antibodies. Comparisons between groups 1 and 3 were evaluated by bivariate and multivariate analysis. RESULTS: Although the prevalence of aPL antibodies was 54%, APS was present in just 9.3% of SLE patients. In our series, besides cardiovascular disease (AOR 3.38, 95% CI 1.11-10.96, p = 0.035), pulmonary involvement (AOR 5.06, 95% CI 1.56-16.74, p = 0.007) and positivity for rheumatoid factor (AOR 4.68, 95%IC 1.63-14.98, p = 0.006) were factors significantly associated with APS-SLE. APS also may coexist with rheumatoid arthritis, Sjögren's syndrome, autoimmune thyroid diseases, systemic sclerosis, systemic vasculitis, dermatopolymyositis, primary biliary cirrhosis and autoimmune hepatitis. CONCLUSIONS: APS is a systemic AD that may coexist with other ADs, the most common being SLE. Awareness of this polyautoimmunity should be addressed promptly to establish strategies for controlling modifiable risk factors in those patients.

Lupus mimickers.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multisystem organ involvement, heterogeneity of clinical features, and variety in degree of severity. The differential diagnosis is a crucial aspect in SLE as many other autoimmune diseases portray clinical similarities and autoantibody positivity. Lupus mimickers refer to a group of conditions that exhibit both clinical features and laboratory characteristics, including autoantibody profiles that resemble those present in patients with SLE, and prompt a diagnostic challenge in everyday clinical practice. Thus, lupus mimickers may present as a lupus-like condition (i.e., 2 or 3 criteria) or as one meeting the classification criteria for SLE. Herein we review and classify the current literature on lupus mimickers based on diverse etiologies which include infections, malign and benign neoplasms, medications, and vaccine-related reactions.
