Coinfections and In-Hospital Mortality in a Group of Patients With HIV/AIDS: A Longitudinal Study.

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.

Prescription Patterns of Inducers and Inhibitors of Cytochrome P450 and Their Potential Drug Interactions in the Real World: A Cross-Sectional Study.

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.

Use of Prophylactic Antibiotics in Hand Surgeries in Colombia.

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.

Pharmacological Management and Potentially Inappropriate Prescriptions for Patients with Acne.

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.

TINU: A Multisystemic Inflammatory Disorder-Case Report and Literature Review.

Background. The syndrome of tubulointerstitial nephritis and uveitis (TINU) is a rare oculorenal condition, mainly seen in children and women. The underlying cause of this disease is unknown. Case Presentation. We report a 24-year-old male without any past medical history, diagnosed with bilateral uveitis and azotemia. Biopsy revealed tubulointerstitial nephritis, consistent with TINU syndrome. Fluorescein angiogram revealed peripheral retinal vasculitis. Discussion. TINU is a rare disorder that needs to be distinguished from sarcoidosis, Sjogren's disease, and tuberculosis. Treatment is indicated in patients with progressive renal insufficiency, consisting of steroid therapy. Most patients recover kidney function. Its early recognition is important to offer the best chance of organ preservation.

Prescription patterns of ambrisentan in some cities of Colombia.

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.

Desenlaces maternos y perinatales asociados con embarazo múltiple en pacientes con diabetes gestacional / Maternal and perinatal outcomes associated with multiple pregnancy in patients with gestational diabetes

Resumen OBJETIVO: Evaluar y comparar la asociación entre diabetes gestacional y desenlaces adversos materno-perinatales en pacientes con embarazo múltiple. MATERIALES Y MÉTODOS: Estudio de cohorte retrospectiva, emprendido en pacientes con embarazo gemelar, sin comorbilidades diagnosticadas y admitidas en un centro de referencia de Medellín, Colombia, entre enero de 2013 y enero de 2017. Se compararon los desenlaces maternos y perinatales hasta el alta de los recién nacidos de madres con y sin diabetes gestacional. Para el análisis estadístico se estimaron asociaciones crudas y ajustadas. RESULTADOS: Se registraron 87 pacientes con embarazo gemelar: 35 en comparación con 52 con y sin diabetes gestacional, respectivamente, entre 228 embarazos gemelares atendidos en el periodo de estudio. El sobrepeso-obesidad predominó en ambos grupos n = 30 de 35 en comparación con n = 35 de 52; p = 0.112. Las variables: primigesta, antecedente de diabetes gestacional y macrosomía fueron significativamente más frecuentes en el grupo de diabetes gestacional p < 0.05. La mediana de semanas de gestación al diagnóstico fue de 27 rango intercuartílico entre 24.3 a 30. En los desenlaces maternos de ambos grupos no se encontraron diferencias estadísticamente significativas. Las semanas de gestación al parto fueron 35 en ambos grupos RR: 0.01; -0.90-0.92; p = 0.980. Solo se registraron muertes neonatales en el grupo de embazadas sin diabetes gestacional n = 52 de 87, en 3 2.9% de los 104 nacidos vivos. El peso al nacimiento fue similar en ambos grupos; no obstante, las embarazadas con diabetes gestacional tuvieron mayor riesgo de taquipnea transitoria que el grupo control RR: 2.06; IC95%: 1.08-3-92, incluso después de ajustar el peso al nacimiento RR: 2.59; IC95%: 1.35-4.57. La diabetes gestacional fue un factor de riesgo independiente de trastorno hidroelectrolítico, especialmente trastornos del potasio RR: 8.09; IC95%: 1.60-41.01. CONCLUSIONES: La diabetes gestacional en mujeres con embarazo gemelar no supone un factor que, en general, empeore los desenlaces maternos y perinatales adversos.

Abstract OBJECTIVE: To evaluate and compare the association between gestational diabetes and adverse maternal-perinatal outcomes in patients with multiple pregnancies. MATERIALS AND METHODS: Retrospective cohort study, undertaken in patients with twin pregnancy, without diagnosed comorbidities, admitted to a reference center in Medellín, Colombia, from January 2013 to January 2017. Maternal and perinatal outcomes were compared until discharge of the newborn of mothers with and without gestational diabetes. For statistical analysis, crude and adjusted associations were estimated. RESULTS: A total of 87 patients with twin pregnancies were registered: 35 vs 52 with and without gestational diabetes, respectively, among 228 twin pregnancies attended in the study period. Overweight/obesity predominated in both groups n = 30 of 35 vs n = 35 of 52; p = 0.112. The variables: primigravida, history of gestational diabetes and macrosomia were significantly more frequent in the gestational diabetes group p < 0.05. The median gestational age at diagnosis was 27 weeks interquartile range between 24.3-30. No statistically significant differences were found in the maternal outcomes of both groups. The gestational age at delivery was 35 weeks in both groups RR: 0.01; -0.90-0.92; p = 0.980. Neonatal deaths were only recorded in the group of pregnant women without gestational diabetes n = 52 of 87, in 3 2.9% of the 104 live births. Birth weight was similar in both groups; However, pregnant women with gestational diabetes had a higher risk of transient tachypnea than the control group RR: 2.06; 95%CI: 1.08-3-92, even after adjusting for birth weight RR: 2.59; 95%CI: 1.35-4.57. Gestational diabetes was an independent risk factor for hydroelectrolyte disorders, especially potassium disorders RR: 8.09; 95%CI: 1.60 -41.01. CONCLUSIONS: Gestational diabetes in women with twin pregnancies is not a factor that, in general, worsens adverse maternal and perinatal outcomes.

Adherence to Inhalation Devices in Patients with Chronic Obstructive Pulmonary Disease.

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.

Use of sacubitril/valsartan in patients with heart failure: evidence from the real world.

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.

Clinical characteristics and use of antibiotics in a group of patients with snake bites in Colombia.

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.

The frequency of complications in a cohort of patients diagnosed with hemophilia A and hemophilia B receiving prophylactic treatment in Colombia: A retrospective noninterventional study.

INTRODUCTION: Hemophilia A and B are disorders associated with the deficit of coagulation factors VIII and IX. OBJECTIVE: Was to determine the incidence of complications in a cohort of patients diagnosed with moderate and severe hemophilia A or B under treatment in a specialized institution. METHODS: A retrospective study of a cohort of patients with replacement therapy for hemophilia A or B, evaluating treatment and complications between January/2012 and July/2019. Sociodemographic, clinical and disease management-related variables were extracted from the medical records. Time to inhibitor development and rate associated with bleeding and hospitalizations were evaluated. RESULTS: A total of 159 male patients were identified with hemophilia A (n = 140; 88.1%) and B (n = 19; 11.9%) with a mean follow-up of 5.9±2.3 years. The mean age was 23.6±16.1 years, hemophilia was reported as severe in 125 patients in hemophilia A (89.3%) and 13 patients in hemophilia B (68.4%). Primary prophylaxis was registered in 17.0% of patients, 44.7% secondary, and 38.3% tertiary, with recombinant factors (n = 84; 52.8%) followed by plasma derived factors (n = 75; 47.2%). The incidence of inhibitor development was 0.3 per 100 patients/year, with mean time to event of 509 days. The incidence of bleeding was 192 per 100 patients/year, especially at the joint (n = 99; 62.3%) and muscle (n = 25; 15.7%) level. The incidence of hospitalization was 3.7 per 100 patients/year. CONCLUSIONS: The most common complication was joint bleeding which was expected in this type of patients. Low proportion of patients developed factor inhibitors during the follow up.

Characterization and effectiveness of a Fracture Liaison Services program in Colombia.

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.

Potentially Inappropriate Use of Opioids in the Management of Migraine in Colombia.

RESEARCH OBJECTIVE: To identify the frequency of opioid use in a group of patients diagnosed with migraine in Colombia. METHODS: Study of a retrospective cohort of patients with a diagnosis of migraine and a first prescription of antimigraine drugs from emergency services and a priority outpatient clinic. Sociodemographic, clinical, and pharmacological variables were identified; a 12-month follow-up was carried out to identify the use of a new opioid. RESULTS: A total of 6309 patients with a diagnosis of migraine were identified, with a mean age of 35.5 ± 12.3 years, of which 81.3% were women. Nonsteroidal anti-inflammatory drugs (51.1%) were the most frequently prescribed medications, followed by ergotamine + caffeine (31.3%), acetaminophen (15.05%), and acetaminophen + codeine (14.4%). At the time of the index, 1300 (20.6%) patients received some opioid. During the follow-up, a total of 1437 (22.8%) patients received a new opioid, of which 31.8% belonged to the group that received an initial opioid and 20.4% to the group that did not receive one, which was statistically significant (OR:1.81; 95%CI:1.58-2.07; p < 0.001). CONCLUSIONS: The frequent use of opioids in the management of migraines is potentially inappropriate and can lead to problems of tolerance, abuse and dependence. This combined with the low prescription of triptans, offers an opportunity for improvements in medical practice.

Patterns and Trends in the Use of Medications for COPD Control in a Cohort of 9476 Colombian Patients, 2017-2019.

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.

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.

Antibiotic Management of Uncomplicated Skin and Soft Tissue Infections in the Real World.

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.

Patterns of use of medications used to treat urinary incontinence and potentially inappropriate prescriptions.

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.

Pattern of prescription drugs used for patients diagnosed with systemic vasculitis / Patrón de prescripción de medicamentos utilizados en pacientes con diagnóstico de vasculitis sistémicas

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.

Use Pattern of Ophthalmic Antiglaucoma Agents with and without Preservatives: A Cross-Sectional Study.

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.

Clinical Characteristics, Patterns of Use, and incidence of Adverse Events in Patients With Nonvalvular Atrial Fibrillation Treated With Oral Anticoagulants in Colombia.

Purpose: The aim was to analyze the characteristics, treatment patterns, and clinical outcomes of Colombian patients with non-valvular atrial fibrillation (NVAF) under treatment with oral anticoagulants (OAs). Patients and Methods: Retrospective cohort in patients with NVAF identified from a drug dispensing database, aged ≥18 years, with first prescription of an OA (index) between January/2013 and June/2018, and a follow-up until June/2019. Data from the clinical history, pharmacological variables, and outcomes were searched. International Classification of Diseases-10 codes were used to identify the patient sample and outcomes. Patients were followed until a general composite outcome of effectiveness (thrombotic events), bleeding/safety or persistence (switch/discontinuation of anticoagulant) events. Descriptive and multivariate analyzes (Cox regressions comparing warfarin and direct oral anticoagulants-DOACs) were carried out. Results: A total of 2076 patients with NVAF were included. The 57.0% of patients were women and the mean age was 73.3±10.4 years. Patients were followed for a mean of 2.3±1.6 years. 8.7% received warfarin before the index date. The most frequent OA was rivaroxaban (n=950; 45.8%), followed by warfarin (n=459; 22.1%) and apixaban (n=405; 19.5%). Hypertension was present in 87.5% and diabetes mellitus in 22.6%. The mean CHA2DS2-VASc Score was 3.6±1.5. The 71.0% (n=326/459) of the warfarin patients presented the general composite outcome, and 24.6% of those with DOACs (n=397/1617). The main effectiveness and safety outcomes were stroke (3.1%) and gastrointestinal bleeding (2.0%) respectively. There were no significant differences between patients with warfarin and DOACs regarding thrombotic events (HR: 1.28; 95% CI: 0.68-2.42), but warfarin was associated with higher bleeding/safety events (HR: 4.29; 95% CI: 2.82-6.52) and persistence events (HR: 4.51; 95% CI: 3.81 -5.33). Conclusion: The patients with NVAF in this study were mainly older adults with multiple comorbidities. Compared to warfarin, DOACs were found to be equally effective, but safer and had a lower probability of discontinuation or switch.
