RESUMEN

Human immunodeficiency virus (HIV) is a global public health problem. Coinfections in HIV patients are frequent complications that increase their mortality. The aim of this study was to assess coinfections and in-hospital mortality in a group of patients infected with HIV in Colombia. A retrospective longitudinal study was carried out. Patients treated in 4 highly complex clinics in Colombia between 2015 and 2023 were included. The cases were identified from International Classification of Diseases codes related to HIV. Sociodemographic, clinical, laboratory and pharmacological variables were collected. Descriptive, bivariate, and multivariable analyses were performed. Of the 249 patients identified, 79.1% were men, and the median age was 38.0 years. Approximately 81.1% had a diagnosis of acquired immune deficiency syndrome (AIDS). Coinfections caused by Mycobacterium tuberculosis (24.1%) and Treponema pallidum (20.5%) were the most frequent. A total of 20.5% of the patients had sepsis, 12.4% had septic shock, and the fatality rate was 15.7%. Antibiotics and antifungals were used in 88.8% and 53.8%, respectively, of the patients. Patients with a diagnosis of HIV before admission, those infected with M. tuberculosis, and those who presented with sepsis were more likely to die, whereas patients who received antiretroviral agent treatment before admission presented a lower risk. In this study, most HIV patients were in an advanced stage of the disease. Coinfection with M. tuberculosis was common and was associated with an increased risk of death. Previous HIV diagnosis and sepsis also increased the risk. Approximately half of the patients with a previous HIV diagnosis were receiving antiretroviral therapy and had a better prognosis.

RESUMEN

PURPOSE: The aim of the investigation was to determine the rate of prophylactic antibiotic use in hand surgeries and the factors related to their use in a group of Colombian patients. METHODS: This was a descriptive study of patients undergoing hand surgery between January 2021 and December 2022. Sociodemographic, clinical, and pharmacological variables were analyzed. The use of prophylactic antibiotics in clean wounds was considered inappropriate except in those who needed placement of an internal fixation implant. Variables related to inappropriate use of prophylactic antibiotics were analyzed. RESULTS: A total of 523 patients were reviewed, with an average age of 44.3 years; 51.2% were men. Most of the patients had a diagnosis of hand fracture (28.7%), trigger finger (24.5%), or ganglion (18.5%). The surgical wound was considered clean in 79.0% of cases. A total of 91.0% received prophylactic antibiotics, mostly cefazolin (63.3%). Some 55.7% were considered inappropriate by our criteria. Women (odds ratio [OR], 3.19; 95% confidence interval [CI], 1.85-5.47), middle-low to high socioeconomic status (OR, 1.88; 95% CI, 1.05-3.38), treatment in clinic #1 (OR, 9.67; 95% CI, 4.81-19.43), history of diabetes mellitus (OR, 2.90; 95% CI, 1.07-7.86), and diagnosis of trigger finger (OR, 19.92; 95% CI, 9.95-39.88), ganglion (OR, 24.53; 95% CI, 11.72-51.34), or tenosynovitis (OR, 19.61; 95% CI, 6.78-56.73) were associated with receiving inappropriate prophylactic antibiotics. At hospital discharge, 60.6% received prophylactic antibiotics. CONCLUSIONS: In a low-middle income country, the use of inappropriate antibiotics in hand surgical procedures is as common as in higher-income countries. The causes appear multifactorial, including the characteristics of the health systems, doctors, and patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

RESUMEN

INTRODUCTION: Both the induction and inhibition of cytochrome P450 are associated with multiple pharmacological interactions, which can lead to loss of efficacy or increase the risk of adverse drug reactions. OBJECTIVE: The aim was to determine the prescription patterns of cytochrome P450-inducing and -inhibiting drugs and their contraindicated and major pharmacological interactions in a group of patients from Colombia. METHODS: This cross-sectional observational study included patients who received drugs that induce or inhibit metabolism and examined their contraindicated and major pharmacological interactions. The patients were identified from a population-based database of drug dispensing. Patients were included between December 1 and December 31, 2021. Inhibitors and inducers of cytochrome P450 were classified based on FDA (Food and Drug Administration) guidelines. Drug interactions were identified using the Micromedex® database. Descriptive, bivariate and multivariable analysis was performed. RESULTS: A total of 63,433 patients were analyzed. Antiseizure medications (35.9%) and antifungals (27.6%) were the most used inducers and inhibitors. A total of 30.1% of patients had potential contraindicated or greater interactions. The following factors were associated with a higher probability of presenting a potential pharmacological interaction: being male (OR 1.14; 95% CI 1.10-1.19), aged 18-39 years (OR 1.77; 95% CI 1.67-1.89) or 40-64 years (OR 1.64; 95% CI 1.56-1.72), having neurological diseases (OR 1.28; 95% CI 1.21-1.35), having psychiatric diseases (OR 3.84; 95% CI 3.58-4.13), having rheumatologic diseases (OR 1.32; 95% CI 1.23-1.41), receiving comedications with statins (OR 1.14; 95% CI 1.08-1.19), receiving comedications with analgesics (OR 1.33; 95% CI 1.27-1.38), receiving comedications with antiparasitics (OR 2.88; 95% CI 2.66-3.11) and an increase in the number of medications (OR 1.24; 95% CI 1.23-1.25). CONCLUSION: Among the users of cytochrome P450 inhibitors and inducers, potential contraindications and greater interactions are very common, especially in men under 65 years of age with comorbidities and polypharmacy.

RESUMEN

The aim was to estimate the vaccination timeliness defined as the proportion of children under 6 years of age who received their immunization in the time range established by the Colombian Expanded Immunization Program (EIP). A retrospective cohort study that collected reports of vaccination opportunities between 2014 and 2019 provided by the Ministry of Health. Age, sex, city, ethnicity, health system affiliation regimen, vaccine applied, and timing of vaccination were considered for the time range under study. A total of 3,370,853 immunized children were included from all regions of the country. More than 80% of children had a timeliness to get most vaccines. The exceptions were yellow fever (17%) and seasonal influenza (42%). No differences in timeliness were found according to geographic region or by health system affiliation regime, but the average timeliness for all vaccines of children of the indigenous population (65.8% ±18.4%) was lower than that of the rest of the population (78·6% ± 19·3%) (p = 0·021). The timeliness for vaccination under the EIP of Colombia is high, with proportions of 72-96%, but intergroup differences were identified, mainly lower timeliness among indigenous people. These findings warrant improvement strategies that would guarantee the immunization of the entire child population.

RESUMEN

Objective: Acne is a chronic inflammatory disease that involves the pilosebaceous follicle. Its pharmacological treatment involves topical and systemic medications, but a heterogeneous group of drugs may exacerbate or induce skin lesions. The aim of this study was to identify the pharmacological management and medications related to the exacerbation of skin lesions in patients diagnosed with acne. Methods: This was a cross-sectional study that identified the outpatient medication prescription patterns of patients with acne from a dispensing database of 8.5 million members of the Colombian Health System. Sociodemographic and pharmacological variables and the identification of prescriptions that were potentially inappropriate due to the risk of worsening acne were considered. Results: A total of 21,604 patients with acne were identified. Median age was 20.8 years (interquartile range: 17.3-27.3 years), and 60.7 percent were female. Treatment mainly involved antibiotics (79.9% of patients), especially doxycycline (66.0%), and retinoids (55.7%). A total of 17.2 percent of patients had potentially inappropriate prescriptions, predominantly progestogens with androgenic properties (8.9%). Female patients (odds ratio [OR]: 3.55; 95% confidence interval [CI]:3.24-3.90) and patients with pathologies such as systemic lupus erythematosus (OR: 18.61; 95% CI: 7.23-47.93) and rheumatoid arthritis (OR: 10.80; 95% CI: 5.02-23.23) were more likely to receive inappropriate prescriptions, and the risk increased with each year of life (OR: 1.02; 95% CI: 1.02-1.03). Limitations: Access to medical records was not obtained to verify clinical characteristics of acne. Conclusion: Patients with acne are excessively treated with systemic antibiotics, counter to clinical practice guidelines. Approximately one-fifth of these patients received some potentially inappropriate medication that could exacerbate their skin lesions.

RESUMEN

INTRODUCTION: Ambrisentan is a selective type A endothelin receptor antagonist that has shown significant effectiveness and safety in the management of patients with pulmonary hypertension. Its use pattern with real-world evidence in Colombia is unknown. OBJECTIVE: The objective of this study is to determine the prescription patterns of ambrisentan in some cities of Colombia. METHODS: A longitudinal descriptive study on the prescription patterns of ambrisentan in patients with pulmonary hypertension (all the groups) was conducted between January 2021 and December 2022 based on a population database of members of the Colombian Health System. Adherence at 1 year was determined using the Medication Possession Ratio (days the drug was dispensed/days from first dispensing to the end of the follow-up period × 100). Descriptive analysis was carried out. RESULTS: Sixty-seven patients taking ambrisentan were identified in 10 cities of the country. The individuals had a median age of 51.5 years (interquartile range-IQR: 39.8-64.0 years), and 82.1% were women. The drug possession rate was 82.2% (IQR: 65.0-96.8%), and persistence at 1 year was present in 49.3% (n = 33) of the cases. The average dose was 8.8 ± 5.0 mg/day, and 76.1% (n = 51) received it in combination therapy, mainly with phosphodiesterase type 5 inhibitors (61.2%, n = 41). CONCLUSIONS: Adherence to ambrisentan was good, but its persistence at 1 year was low. The dosages of the drug used were in accordance with the recommendations of the clinical practice guidelines, and it was used in combination therapy, especially with phosphodiesterase 5 inhibitors.

RESUMEN

Purpose: Chronic obstructive pulmonary disease (COPD) affects millions of people around the world. Poor adherence to treatment contributes to increased severity of symptoms, morbidity, and mortality. The objective of this study was to establish the adherence of patients diagnosed with COPD by their devices for inhalation in a group of patients, Colombia. Patients and Methods: This was a cross-sectional study of patients treated in the Colombian health system. Adherence to inhalation devices was evaluated with the TAI-10 instrument (Inhaler Adherence Test). A score of 50 points was considered good adherence. Results: A total of 500 patients from 84 cities were identified, with a median age of 79.0 years, and 59.2% were women. A total of 45% had GOLD B COPD, and 56.6% had good adherence. Average adherence was 47.4±5.3 points, and no significant differences were found according to inhalation devices (p=0.949). Training performed by specialist physicians (OR: 1.75; 95% CI: 1.17-2.62), use of an inhaler for less than 1 year (OR: 1.59; 95% CI: 1.04-2.43), use of short-acting ß2-adrenergic agonists (OR: 1.58; 95% CI: 1.05-2.38) and increased satisfaction with the inhalation device (OR: 1.09; 95% CI: 1.04-1.14) were associated with good adherence, while those from the central region (OR: 0.55; 95% CI: 0.36-0.83), who had a COPD evolution time of less than 5 years (OR: 0.57; 95% CI: 0.37-0.98) and had diabetes mellitus (OR: 0.60; 95% CI: 0.37-0.98) had lower adherence. Conclusion: Adherence to treatment with inhaled bronchodilators and glucocorticoids were not very high, with no significant differences by type of inhalation device. Satisfaction and training by specialists increased adherence.

RESUMEN

BACKGROUND: To characterize the use of sacubitril/valsartan in a group of patients with heart failure in Colombia. RESEARCH DESIGN AND METHODS: Follow-up study of patients with heart failure who started sacubitril/valsartan and were affiliated with the Colombian health system between 2019 and 2021. Sociodemographic, clinical, and pharmacological variables and adherence and persistence of use were identified. RESULTS: A total of 514 patients were identified, with a mean age of 65.7 years, 73.7% of whom started sacubitril/valsartan at low doses, and only 12.5% reached the maximum dose. Adherence was 78.2% and persistence was 56.8% at 1 year of follow-up. The increase in systolic blood pressure (odds ratio (OR): 1.01; 95% CI: 1.00-1.03) and the use of ß-blockers (OR: 2.63; 95% CI: 1.42-4.85) were correlated with a greater persistence, while receiving furosemide (OR: 0.59; 95% CI: 0.39-0.89) and not having received renin - angiotensin - aldosterone system inhibitors in the 3 months before starting sacubitril/valsartan (OR: 0.48; 95% CI: 0.31-0.76) were associated with lower persistence. CONCLUSIONS: The persistence of treatment 1 year after starting sacubitril/valsartan was not high, and a small proportion of patients reached the target dose of the drug. Nontitration of the drug dose was common.

RESUMEN

Intestinal parasites continue to be a public health problem in low- and middle-income countries. Broad use of anthelmintics during deworming programs is still necessary in many regions. However, description of the usage of these medications in general medical practice has been limited. The objective of this study was to determine the use of anthelmintic drugs and their indications in a group of Colombian patients. This was a descriptive study from a drug-dispensing database, identifying patients with prescriptions for anthelmintic drugs. A total of 381 cases were randomly selected, and their medical records were reviewed, analyzing sociodemographic, clinical, and pharmacological variables (indication of use). The lack of diagnosis registration or clinical manifestations of parasites was determined as a prescription without indication. In total, 50.9% (n = 194) of patients were female, and 67.4% of all patients were under 18 yr of age. The diagnosis of helminthiases was clearly stated in 114 (29.9%) patients, and only 4.2% (n = 16) of these had microbiological confirmation. The most commonly used anthelmintic drug was albendazole (70.4% of all prescriptions). The use of anthelmintics was not indicated in 266 cases (69.8%). Nutritional supplements or vitamin prescriptions were associated with using anthelmintics without indication (odds ratio: 2.25; 95% confidence interval: 1.26-4.03). A high proportion of patients lacked symptoms or diagnoses in their clinical records that supported the use of anthelmintic drugs.

RESUMEN

BACKGROUND: Irritable bowel syndrome (IBS) is a functional disorder that leads to abdominal pain; its diagnosis is based on Rome IV criteria (recurrent abdominal pain at least 1 day per week in the last 3 months with more than two of the following: related to defecation, associated with a change in stool frequency and/or with a change in stool appearance). OBJECTIVE: To characterize an outpatient population diagnosed with IBS in Colombia during 2017-2018. METHODS: A cross-sectional study based on a review of clinical records of patients with a primary diagnosis of IBS. A representative sample of 380 individuals was recruited from a population of 38,182 people with a new diagnosis of IBS from a drug-claim database. Sociodemographic, clinical (symptoms, type of IBS, alarm features, etc.), treatment (pharmacological or not), and follow-up variables (for those with additional medical care at 3-12 months) were analyzed. The diagnosis and treatment used in the consultation were compared with clinical guidelines. RESULTS: Most of the 380 patients were women (n = 238; 62.6%), and the mean age was 40.1 ± 15.0 years. None of the physicians recorded the Rome IV criteria in the medical records. Unclassified IBS was the most prevalent subtype (n = 311; 81.8%), and the main symptom was abdominal pain (n = 327; 86.1%). Only 73 patients (19.2%) had follow-up data. The most frequently used drugs were aluminum hydroxide (n = 203; 53.4%) and hyoscine N-butyl bromide (n = 200; 52.6%). Regarding drugs included in the clinical practice guidelines, 19 people received loperamide (5.0%), 3 received trimebutine (0.8%), and 1 received sertraline (0.3%). CONCLUSIONS: The patients were diagnosed without clearly established criteria, and they were treated symptomatically with little follow-up.

RESUMEN

Introduction: Millions of snake bites occur worldwide each year. Clinical practice guidelines generally do not recommend the use of prophylactic antibiotics. Objective: To determine the sociodemographic, clinical, and pharmacological variables and the use of antibiotics in a group of patients with snake bites in Colombia. Methods: A retrospective cross-sectional study was carried out. Patients affiliated with a Colombian health insurer who presented with snake bites between 2015 and 2022 were included. The cases were identified from the National Public Health Surveillance System. Sociodemographic, clinical and pharmacological variables were identified. Descriptive and bivariate analyses were performed. Results: A total of 643 patients were analyzed, with a median age of 30.8 years, and 74.7% were men. The most frequently identified genus of snake was Bothrops (88.8%), and most incidents were classified as mild ophidian accidents (61.6%). A total of 59.7% of patients received snake antivenom. A total of 13.8% and 2.2% of the patients had cellulitis or abscesses, respectively. A total of 63.5% received antibiotics (50.6% for prophylaxis and 12.9% for treatment), especially cephalexin (25.9%), and most of the antibiotic management was considered inappropriate (91.7%). Conclusion: Most patients with snake bites received antibiotics, especially for prophylactic purposes, a clinical behavior that goes against current evidence. The use of antibiotics with an unsuitable spectrum for the microorganisms that are usually found in the wounds of these patients is frequent. The development of local clinical practice guidelines is required to help reduce the overprescription of antibiotics, as the excessive use of antimicrobials is the main determinant of antimicrobial resistance.

RESUMEN

PURPOSE: Fracture Liaison Services programs reduce mortality and the risk of refracture and increase treatment and adherence rates. Greater coverage is an important priority for the future. The aim was to determine the characteristics of patients over 50 years old who suffered fractures and the effectiveness of a Fracture Liaison Services program in a health care institution in Colombia. METHODS: This was a retrospective follow-up study of a cohort of patients with vertebral and nonvertebral fractures managed in a Fracture Liaison Services program. Sociodemographic, clinical and pharmacological variables were identified. Key performance indicators were used to evaluate the effectiveness of the program. Descriptive and bivariate analysis was performed. RESULTS: A total of 438 patients were analyzed. The average age was 77.5 years, and 78.5% were women. Hip and vertebral fractures were the most common (25.3% and 24.9%, respectively). Vertebral fractures prevailed in men (33.0% vs 22.7%; p = 0.041) and those of the radius/ulna in women (20.3% vs 10.6%; p = 0.031). A total of 29.7% had experienced a previous fracture, and 16.7% had received antiosteoporosis drugs. A total of 63.5% of the cases were managed surgically. At discharge, 58.8% received prescriptions for calcium/vitamin D, and 50.7% with prescriptions of antiosteoporotic therapy, especially teriparatide (21.2%) and denosumab (16.4%), without significant differences by sex. However, in women with hip fractures, anti-osteoporotic management prevailed (83.7% vs 64.0; p = 0.032). The effectiveness of the overall program per year was 74.6%. On follow-up, only 9.1% of patients had experienced a new fall, and of those 3.7% presented a new fracture. A total of 4.3% died during follow-up. CONCLUSIONS: Good adherence to the recommendations of the country's clinical practice guidelines was found, and overall, the effectiveness of the program was very satisfactory, with a low incidence of new fractures during follow-up. Fracture Liaison Services programs reduce mortality and the risk of refracture. A retrospective follow-up study of a cohort of patients with vertebral and nonvertebral fractures managed in a Fracture Liaison Services, showed that the effectiveness was 73.6%. On follow-up, 9.1% of patients had experienced a new fall, and of those 3.7% presented a new fracture.

RESUMEN

This study determined the coverage and timeliness of immunization in children <6 y from Risaralda, Colombia. A retrospective cross-sectional study evaluated data from a vaccination coverage and timeliness verification survey conducted in 2019, including 2457 children <6 y from Risaralda, Colombia. Variables included demographics, a record of vaccinations included in the Colombian Vaccination Plan, and date of immunization. Vaccination was defined as timely until 29 d after the day established by the plan. Coverage was over 95% for all vaccinations, except the boosters of diphtheria/pertussis/tetanus (DTP) and oral polio at 18 months (91.0%), influenza (85.6%), and yellow fever (49.2%). Most surveyed children demonstrated very high timeliness of vaccination, with values close to, or over, 90%, although there were exceptions for pentavalent (DTP+Haemophilus influenzae type B+hepatitis B) and polio vaccines at 6 months (79.4%), influenza (85.6%), and yellow fever (49.2%). Before the COVID-19 pandemic, Colombian Vaccination Plan demonstrated high coverage and timeliness of vaccination of children <6 y of age; however, timeliness for the third dose of DTP-Hib-HBV and polio showed opportunities for improvement.

RESUMEN

Purpose: Chronic obstructive pulmonary disease (COPD) affects approximately 174 million people worldwide. The objective was to determine the trends of COPD medication use in a group of Colombian patients. Patients and Methods: This was a retrospective study on prescription patterns of bronchodilators and other medications used in COPD from a population database with follow-up at 12 and 24 months. Patients older than 18 years of age of any sex with a COPD diagnostic code between 2017 and 2019 were included. Sociodemographic variables, medications, treatment schedules for COPD, comorbidities, comedications, and the specialty of the prescriber were considered. Results: Data from 9476 people with COPD was evaluated. The mean age was 75.9 ± 10.7 years, 50.1% were male, and 86.8% were prescribed by a general practitioner. A total of 57.9% had comorbidities, most often hypertension (44.4%). At the baseline measurement, on average, they received 1.6 medications/patient, mainly short-acting antimuscarinics (3784; 39.9%), followed by short-acting ß-agonists (2997, 31.6%) and inhaled corticosteroids (ICS) (2239, 23.6%); more than half (5083, 53.6%) received a long-acting bronchodilator. Prescription of triple therapy (antimuscarinic, ß-agonist, and ICS) went from 645 (6.8%) at baseline to 1388 (20.6%) at the 12-month mark. Conclusion: This group of patients with COPD treated in Colombia frequently received short-acting bronchodilators and ICS, but a growing proportion are undergoing controlled therapy with long-acting bronchodilators, a situation that can improve the indicators of morbidity, exacerbations, and hospitalization.

RESUMEN

Background: Skin and soft tissue infections are one of the main causes of consultations worldwide. The objective was to determine the treatment of a group of patients with uncomplicated skin and soft tissue infections in Colombia. Methods: Follow-up study of a cohort of patients with skin infections who were treated in the Colombian Health System. Sociodemographic, clinical and pharmacological variables were identified. Treatments were evaluated using clinical practice guidelines for skin infections. Results: A total of 400 patients were analyzed. They had a median age of 38.0 years and 52.3% were men. The most commonly used antibiotics were cephalexin (39.0%), dicloxacillin (28.0%) and clindamycin (18.0%). A total of 49.8% of the subjects received inappropriate antibiotics, especially those with purulent infections (82.0%). Being cared for in an outpatient clinic (OR: 2.09; 95% CI: 1.06-4.12), presenting pain (OR: 3.72; 95% CI: 1.41-9.78) and having a purulent infection (OR: 25.71; 95% CI: 14.52-45.52) were associated with a higher probability of receiving inappropriate antibiotics. Conclusions: Half of patients with uncomplicated skin and soft tissue infections were treated with antibiotics that were not recommended by clinical practice guidelines. This inappropriate use of antibiotics occurred in the vast majority of patients with purulent infections because the antimicrobials used had no effect on methicillin-resistant Staphylococcus aureus.

RESUMEN

Background: The pharmacological treatment of urinary incontinence (UI) may involve bladder antimuscarinics, which can generate risks in the elderly. Objective: The aim was to determine the treatment patterns of a group of patients with UI and possible potentially inappropriate prescriptions. Design and methods: This was a cross-sectional study that identified prescription patterns of medications for outpatient use in patients with UI between December 2020 and November 2021 based on a population database of members of the Colombian Health System. Patients were identified based on the codes of the international classification of diseases, version-10. Sociodemographic and pharmacological variables were considered. Results: A total of 9855 patients with UI were identified, with a median age of 72 years, and 74.6% were women. Unspecified UI was the most frequent form (83.2%), followed by specified UI (7.9%), stress UI (6.7%), and UI associated with an overactive bladder (2.2%). A total of 37.2% received pharmacological treatment, mainly with bladder antimuscarinics (22.6%), mirabegron (15.6%), and topical estrogens (7.9%). Pharmacological management predominated in UI associated with overactive bladder, in women and in patients between 50 and 79 years of age. Of the patients who received bladder antimuscarinics, 54.5% were 65 years old or older, and 21.5% also had benign prostatic hyperplasia, sicca syndrome, glaucoma, constipation, or dementia. A total of 2.0% of women had been prescribed systemic estrogens and 1.7% had been prescribed peripheral α-adrenergic antagonists. Conclusion: Differences in the prescriptions were found according to the type of UI, sex, and age group. Potentially inappropriate or risky prescriptions were common.

RESUMEN

ABSTRACT Introduction: Vasculitis is a heterogeneous group of diseases characterized by inflammation of the blood vessel wall, which can cause thrombosis, stenosis, or occlusion. Its pharmacological management involves corticosteroids and conventional and biological disease-modifying antirheumatic drugs. Objectives: The objective was to determine the different types of systemic vasculitis and their pharmacological treatment in a group of patients from Colombia, 2019-2020. Materials and methods: This was a cross-sectional study that identified different types of systemic vasculitis and their pharmacological management in a group of patients from a drug-dispensing database of approximately 8.5 million people. Sociodemographic, comorbidity and pharmacological variables were considered. A descriptive analysis was performed. Results: A total of 621 patients with a diagnosis of systemic vasculitis were identified. The patients had a median age of 55.0 years, and 74.4% were women. The most common vasculitis types were those limited to the skin (30.1%), granulomatosis with polyangiitis (17.6%), and necrotizing vasculopathy (10.8%). A total of 81.0% of cases received corticosteroid prescriptions, 44.0% received azathioprine, and 24.0% received methotrexate; only 1.6% were prescribed biological antirheumatic drugs. Cardiovascular diseases were the most common comorbidity. Conclusions: The pattern of prescription medications used for patients diagnosed with systemic vasculitis is heterogeneous. Much of this population has associated comorbidities, which increases the use of medications according to the current management guidelines.

RESUMEN Introducción: Las vasculitis son un grupo heterogéneo de enfermedades caracterizadas por la inflamación de la pared de los vasos sanguíneos, lo cual puede llegar a ocasionar trombosis, estenosis u oclusión. Su manejo farmacológico incluye corticoesteroides, antirreumáticos modificadores de enfermedad convencionales y biológicos. Objetivos: El objetivo de este estudio fue determinar los diferentes tipos de vasculitis sistémicas y su tratamiento farmacológico en un grupo de pacientes de Colombia. Materiales y métodos: Se trató de un estudio de corte transversal que identificó los diferentes tipos de vasculitis sistémicas y su manejo farmacológico en un grupo de pacientes, a partir de una base de datos de dispensación de medicamentos de aproximadamente 8,5 millones de personas. Se consideraron variables sociodemográficas, comorbilidades y variables farmacológicas, y se hizo un análisis descriptivo. Resultados: Se identificaron 621 pacientes con diagnóstico de vasculitis sistémicas, con una mediana de edad de 55,0 anos, el 74,4% mujeres, siendo las vasculitis más frecuentes las limitadas a la piel (30,1%), la granulomatosis con poliangeitis (17,6%) y la vasculopatía necrosante (10,8%). El 81,0% de los casos recibió corticoesteroides, el 44,0% azatioprina y el 24,0 metotrexate, mientras que solo el 1,6% tenía prescritos antirreumáticos biológicos. Las comorbilidades cardiovasculares fueron las más comunes. Conclusiones: El patrón de prescripción de medicamentos utilizados en pacientes con diagnóstico de vasculitis sistémicas es heterogéneo y acorde con las guías actuales de manejo. Gran parte de esta población cursa con comorbilidades asociadas, lo cual incrementa el uso de medicamentos.

RESUMEN

BACKGROUND: Different drugs have been approved to reduce the intraocular pressure. However, most of them contain preservatives to maintain sterility and these can be toxic to the ocular surface. The aim was to determine the patterns of use of antiglaucoma agents and ophthalmic preservatives in a group of patients from Colombia. METHODS: A cross-sectional study that identified ophthalmic antiglaucoma agents from a population database of 9.2 million. Sociodemographic and pharmacological variables were considered. Descriptive and bivariate analyses were performed. RESULTS: A total of 38,262 patients were identified, with a mean age of 69.2 ± 13.3 years, and 58.6% were women. A total of 98.8% were prescribed antiglaucoma drugs in multidose containers. The most widely used were prostaglandin analogs (59.9%), especially latanoprost (51.6%) and ß-blockers (59.2%). A total of 54.7% of patients received combined management, especially with fixed-dose combination (FDC) drugs (41.3%). A total of 94.1% used antiglaucoma drugs with preservatives (benzalkonium chloride, 68.4%). CONCLUSIONS: The pharmacological treatment of glaucoma was very heterogeneous, but the most commonly used therapeutic groups were in accordance with the recommendations of clinical practice guidelines but with differences by sex and age. Most of the patients were exposed to preservatives, especially benzalkonium chloride, but the wide use of FDC drugs can minimize toxicity on the ocular surface.

RESUMEN

INTRODUCTION: Systemic lupus erythematosus is an autoimmune disease associated with serious complications and high costs. The aim was to describe the clinical characteristics and health care resource utilization of a Colombian systemic lupus erythematosus outpatient cohort. METHODS: This was a retrospective descriptive study. Clinical records and claims data for systemic lupus erythematosus patients from ten specialized care centers in Colombia were reviewed for up to 12 months. Baseline clinical variables, Systemic Lupus Erythematosus Disease Activity Index, drug use, and direct costs were measured. Descriptive statistics were analyzed using SPSS. RESULTS: A total of 413 patients were included; 361 (87.4%) were female, and the mean age was 42 ± 14 years. The mean disease evolution was 8.9 ± 6.0 years; 174 patients (42.1%) had a systemic manifestation at baseline, mostly lupus nephritis (105; 25.4%). A total of 334 patients (80.9%) had at least one comorbidity, mainly antiphospholipid syndrome (90; 21.8%) and hypertension (76; 18.4%). The baseline Systemic Lupus Erythematosus Disease Activity Index score was 0 in 215 patients (52.0%), 1-5 in 154 (37.3%), 6-10 in 41 (9.9%) and 11+ in 3 (0.7%). All patients received pharmacological therapy, and the most common treatment was corticosteroids (293; 70.9%), followed by antimalarials (chloroquine 52.5%, hydroxychloroquine 31.0%), immunosuppressants (azathioprine 45.3%, methotrexate 21.5%, mycophenolate mofetil 20.1%, cyclosporine 8.0%, cyclophosphamide 6.8%, leflunomide 4.8%) and biologicals (10.9%). The mean annual costs were USD1954 per patient/year, USD1555 for antirheumatic drugs (USD10,487 for those with biologicals), USD86 for medical visits, USD235 for drug infusions and USD199 for laboratory tests. CONCLUSIONS: Systemic lupus erythematosus generates an important economic and morbidity burden for the Colombian health system. Systemic lupus erythematosus outpatient attention costs in the observation year were mainly determined by drug therapy (especially biologics), medical visits and laboratory tests. New studies addressing the rate of exacerbations, long-term follow-up or costs related to hospital care are recommended.
