Efficacy of Oral, Topical, and Intradermal Tranexamic Acid in Patients with Melasma - A Meta-Analysis

Background and Objective

Tranexamic acid (TXA) has recently shown promising results in the treatment of melasma. The objective of this study was to generate statistical evidence on the efficacy of TXA with different routes.

Materials and Methods

We searched studies in PubMed, Cochrane, ClinicalTrials.gov, and Scopus using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. A change in melasma area and severity index (MASI)/modified MASI score from the baseline at the end of 8 and 12 weeks was seen. Inverse variance method was used for continuous data to measure standard mean difference (SMD) at a 95% confidence interval (CI). RevMan version 5.4 was used for analysis, and statistical heterogeneity across studies was reported using I2 statistics. P < 0.05 was considered significant.

Results

Totally, 28 randomized control trials were included. At 8 weeks, oral TXA showed a significant change in SMD of 1.61, 95% CI 0.44-2.79, P = 0.007; at 12 weeks, oral TXA showed SMD of 2.39, 95% CI 1.42-3.35, P < 0.00001 compared to adjuvant treatment. At 8 weeks, topical TXA did not show a significant change with SMD of -0.05, 95% CI -1.08-0.97, P = 0.92; at 12 weeks, topical TXA did not show a significant change with SMD of 0.66, 95% CI -0.10-1.42, P = 0.09 compared to adjuvant treatment. Similarly, for intradermal TXA at 8 weeks, results were not significant with SMD of 1.21, 95% CI -0.41-2.83, P = 0.14, and at 12 weeks, SMD was -0.55, 95% CI -2.27-1.18, P = 0.54 compared to adjuvant treatment.

Conclusion

Tranexamic acid in an oral formulation can be used along with adjuvant treatment for the management of melasma. Data are still required for topical and intradermal routes. Owing to the fact that our included studies had a lot of heterogeneity, more research is needed along with addressing the adverse effects of tranexamic acid as well as its variation in different skin colors.

Modified computed tomography severity index in evaluation of acute pancreatitis and its correlation with clinical outcome: A prospective observational study from a tertiary care teaching hospital, India

Introduction

Acute pancreatitis (AP) is one of the most common yet, the most complex and challenging abdominal emergencies encountered by clinicians globally. It runs an unpredictable course. One-fifth of all AP patients develop complications. Many prognostic predictive scoring systems are used for AP. The aim of our study was to evaluate the usefulness of modified computed tomography severity index (MCTSI) scores to predict the need for intensive care unit (ICU) stay, complications, and mortality in patients of AP.

Methodology

An observational, prospective study was conducted for 1 year. Fifty cases diagnosed as AP were included in this study. Contrast-enhanced computed tomography of the abdomen and pelvis was carried out in all patients. MCTSI was calculated according to CT findings. Patients' demographic details, clinical findings, duration of hospital stay, complications, and interventions were recorded. SPSS version 26.0 was used for statistical analysis.

Results

A.

total of 50 patients were enrolled in the study. The mean age was 43.34 years. Total hospital stay was 9.02 ± 6.47 days, mean ward stay was 6.08 ± 2.73, and mean ICU stay was 2.94 ± 4.7 days. Five deaths were reported. There was a significant correlation between the necessity of ICU admission and grade of pancreatitis. There is significant correlation with age and ICU stay (r = 0.344, P = 0.014), age and ward stay (r = -0.340, P = 0.016), total duration of hospital stay and MCTSI score (r = 0.742, P = 0.000), duration of ward stay and MCTSI score (r = -0.442, P = 0.001), and strong correlation with duration of ICU stay and MCTSI score (r = 0.869, P = 0.000). A higher MCTSI score was significantly associated with the presence of local as well as systemic complications and with death (P = 0.0001).

Conclusion

Grading by modified CT severity index has a significant direct correlation with the necessity of ICU admission, duration of ICU stay, and total duration of hospital stay. A modified CT severity index can be used to predict the possibility of developing local and systemic complications as well as the need for interventions. Modified CTSI is a reliable predictor of clinical course and outcome in cases of acute pancreatitis.

Impact of newer direct-acting antiviral drugs based on quality-adjusted life years: A prospective pharmacoeconomic study in hepatitis C patients

Context

The Indian government is dispensing newer direct-acting antiviral (DAA) drugs, which may have impact on hepatitis C virus (HCV) patients' quality of life (QoL).

Aims

To evaluate different DAA regimens and impact on QoL in terms of quality-adjusted life year (QALY) in HCV patients and to measure cost-effectiveness.

Methods

This prospective, observational study was carried out on patients who were diagnosed with HCV. Recruited patients were followed up until 12-24 weeks. Patients were recruited following the selection criteria. Along with demographic and drug details, the regimens used were analyzed and evaluated for cost minimization, cost-effectiveness, and cost-utility analysis. For health quality check, the Chronic Liver Disease questionnaire (CLDQ) was used which was also used for QALY assessment. Data were entered into MS Excel 2016. Difference in between the regimens for total cost was done using unpaired t-test and ANOVA test using SPSS 25.0. Overall cost-effectiveness, cost minimization, cost utility and cost of illness analysis was also calculated. P < 0.05 was considered statistically significant.

Results

A total of 31 patients were enrolled. A total of five drugs, namely, sofosbuvir, daclatasvir, ribavirin, velpatasvir, and ledipasvir were widely used. Sofosbuvir was most common (46.25%)component of drug combination in our study. A total of five types of regimen were used according to the genotype of patients. With 44,260.13 ± 15,884.92 INR of the total drug cost, 70.97% of patients spent around 30,000-40,000 INR for the whole pharmacotherapy. The total indirect cost was 2768.39 ± 3916.13 INR with the total direct cost of 48,660.90 ± 15,356.39 INR. The total cost including direct as well as indirect cost spent during 6-month therapy by 61.29% of patients was 40,000-50,000 INR. Based on the CLDQ score, QoL was 64.1 ± 25. Regimen 2 (sofosbuvir + velpatasavir) stood out with the lowest cost. Regimen 5 (ribavirin [200 mg] + sofosbuvir [400 mg] + velpatasvir [100 mg]) was found to be the most cost-effective. Considering 1 life year with good health after treatment, QALY was 0.31.

Conclusions

Ribavirin (200 mg) + sofosbuvir (400 mg) + velpatasvir (100 mg) was found to be the cost-effective and cost-saving regimen among DAAs.

Off-label drugs use in neurology outpatient department: A prospective study at a tertiary care teaching hospital

Background:

Off-label drug use refers to any use of an approved or cleared drug that is not included in that product's approved labeling or cleared indications for use. It may be in terms of indication, age group, dosage, or route of administration. Off-label drug prescriptions are common neurology practice.

Aim:

The aim of the study is to evaluate the prevalence pattern of off-label drug use in neurology.

Subjects and Methods:

A prospective, observational, cross-sectional study was carried out in the neurology outpatient department of tertiary care teaching hospital. Data of patients above 18 years were recorded after obtaining their informed consent. The National Formulary of India (NFI) and British National Formulary (BNF) guidelines were used as tools for evaluation of the prevalence of off-label drug use.

Results:

A total of 709 drugs were recorded from the prescription data of 205 patients collected in the duration of 2 months. The results reported 145 (20.45%) and 317 (44.71%) drugs as off-label as per the NFI and BNF, respectively. Prescriptions with minimum 1 off-label drug use were 78.05% – BNF and 46.83% – NFI. The indication was one of the most common causes of drugs being off-label. Out of the total 317 off-label drug uses reported, 84 were unlicensed drug use as per the BNF. There is strong and positive correlation established between the age of the patients, number of drugs prescribed, and total off-label drugs prescribed per patient in the given study. The most common off-label drug use noted was with clonazepam and amitriptyline.

Conclusion:

Off-label prescriptions practice is common in the field of neurology.

Students' perceptions on feedback module in pharmacology

CONTEXT

Feedback is an integral part of formative assessment though underutilized in medical education. The objective of this study was to review our feedback module through students' perceptions.

METHODOLOGY

We have developed a feedback module which is practiced by us for last 10 years for term ending examination that gives collective feedback to the whole class, followed by individual student-teacher interactions. Students were also exposed to 6-7 multiple choice questions (MCQs) based assessment during the course of pharmacology. Immediately after each MCQ test the answer keys is displayed along with an explanation. Two classes of students were requested to give their perceptions about the feedback by responding on Likert scale for the statements in the questionnaire. All the 206 students who volunteered for the study were enrolled in the study. Mann-Whitney test was used to calculate the difference in perceptions.

RESULTS

Of 278 students of two classes, 206 responded (74%). Students' agreement varied from 93% to 98% for 5 items in the questionnaire for the feedback after term ending examinations. Perception of students attending one or more than one feedback session did not differ significantly. For MCQs, tests agreement was 91% to 98% for the 4 items. There was no significant difference between two classes in their perceptions regarding feedback practices (P < 0.05).

CONCLUSION

Students gave a favorable opinion for our feedback module. In the medical colleges with a large number of students, this module is feasible for feedback in formative assessment in the form of written tests.

Use of potentially inappropriate medications in hospitalized elderly at a teaching hospital: a comparison between Beers 2003 and 2012 criteria

Objectives:

To detect the prevalence and pattern of use of Potentially inappropriate medications (PIMs) in hospitalized elderly patients of a tertiary care teaching hospital using Beers 2012 criteria and to compare the same with Beers 2003 criteria.

Materials and Methods:

Prescriptions of the elderly patients aged 65 years and above were collected from the medicine ward and analyzed. PIMs were identified with help of Beers 2003 and Beers 2012 criteria and comparison was made between the two criteria. Predictors associated with use of PIM were identified using bivariate and multivariate logistic regression analysis.

Results:

A total of 210 patients received 2,267 drugs. According to Beers 2003 criteria, 60 (28.57%) elderly patients received at least one PIM and 2.9% drugs were prescribed inappropriately. According to Beers 2012 criteria, 84 (40%) elderly received at least one PIM while 22 (10.47%) received multiple PIMs and about 5% drugs were prescribed inappropriately. The most commonly prescribed PIM was mineral oil-liquid paraffin (30, 14.3%) followed by spironolactone (25, 11.9%), digoxin (19, 9%), and benzodiazepines (14, 6.7%). There was a significant association between the number of patients receiving more than six drugs and the use of PIMs (P < 0.01). Use of more than 10 drugs was a significant predictor for use of PIMs in the elderly.

Conclusion:

The study shows high prevalence of prescribing PIMs in hospitalized elderly patients. Beers 2012 criteria are more effective in identifying PIMs than Beers 2003 criteria.

A study of potential adverse drug-drug interactions among prescribed drugs in medicine outpatient department of a tertiary care teaching hospital

Objective:

To evaluate prevalence, types, and severity of potential adverse drug-drug interaction in medicine out-patient department.

Materials and Methods:

A single-point, prospective, and observational study was carried out in medicine OPD. Study began after obtaining approval Institutional Ethics Committee. Data were collected and potential drug-drug interactions (pDDIs) were identified using medscape drug interaction checker and were analyzed.

Result:

A total of 350 prescriptions with mean age 52.45 ± 14.49 years were collected over a period of 5 months. A total of 2066 pDDIs were recorded with mean of 5.90 ± 6.0. The prevalence of pDDI was 83.42%. Aspirin was most frequently prescribed drug in 185 (10.15%) out of total of 1821 drugs It was also the most frequent drug implicated in pDDI i.e. in 48.16%. The most common pDDI identified was metoprolol with aspirin in 126 (6.09%). Mechanism of interactions was pharmacokinetic in 553 (26.76%), pharmacodynamic in 1424 (68.92%) and 89 (4.30%) having an unknown mechanism. Out of all interactions, 76 (3.67%) were serious, 1516 (73.37%) significant, and 474 (22.94%) were minor interaction. Age of the patients (r = 0.327, P = 0.0001) and number of drugs prescribed (r = 0.714, P = 0.0001) are significantly correlated with drug interactions.

Conclusion:

Aspirin being the most common drug interacting. The use of electronic decision support tools, continuing education and vigilance on the part of prescribers toward drug selection may decrease the problem of pDDIs.

Evaluation of rationality in prescribing, adherence to treatment guidelines, and direct cost of treatment in intensive cardiac care unit: A prospective observational study

BACKGROUND

Cardiovascular diseases (CVDs) remain the most common cause of sudden death. Hence, appropriate drug therapy in intensive cardiac care unit (ICCU) is crucial in managing cardiovascular emergencies and to decrease morbidity and mortality.

OBJECTIVE

To evaluate prescribing pattern of drugs and direct cost of therapy in patients admitted in ICCU.

MATERIALS AND METHODS

Patients admitted in ICCU of a tertiary care teaching hospital were enrolled. Demographic data, clinical history, and complete drug therapy received during their stay in ICCU were noted. Data were analyzed for drug utilization pattern and direct cost of treatment calculated using patient's hospital and pharmacy bills. Rationality of therapy was evaluated based on American College of Cardiology/American Heart Association (ACC/AHA) guidelines.

RESULT

Data of 170 patients were collected over 2 months. Mean age of patients was 54.67 ± 13.42 years. Male to female ratio was 2.33:1. Most common comorbid condition was hypertension 76 (44.7%). Most common diagnosis was acute coronary syndrome (ACS) 49.4%. Mean stay in ICCU was 4.42 ± 1.9 days. Mean number of drugs prescribed per patient was 11.43 ± 2.85. Antiplatelet drugs were the most frequently prescribed drug group (86.5%). Mean cost of pharmacotherapy per patient was '2701.24 ± 3111.94. Mean direct cost of treatment per patient was '10564.74 ± 14968.70. Parenteral drugs constituted 42% of total drugs and 90% of total cost of pharmacotherapy. Cost of pharmacotherapy was positively correlated with number of drugs (P = 0.000) and duration of stay (P = 0.027).

CONCLUSION

Antiplatelet drugs were the most frequently prescribed drug group. Mean number of drugs per encounter were high, which contributed to the higher cost of pharmacotherapy. ACC/AHA guidelines were followed in majority of the cases.

Drug utilization in emergency medicine department at a tertiary care teaching hospital: A prospective study

Background and Objectives:

The practice of emergency medicine has the primary mission of evaluating, managing and providing treatment to those patients with unexpected injury or illness. Instituting appropriate therapy is necessary for safety of the patients and to decrease mortality and morbidity. The objectives were to study the drug utilization pattern and direct cost of therapy in emergency medicine department of a tertiary care teaching hospital.

Materials and Methods:

Data of the patients admitted to emergency medicine department was collected prospectively for 48 h from the time of admission over 2 months. The prescriptions were analyzed for drug use pattern and direct cost of therapy was calculated.

Results:

A total of 156 patients received 1635 drugs with the mean of 9.99 ± 2.55 drugs/patient. Most common diagnosis was acute coronary syndrome 35 (21.79%). Ondansetron 135 (86.53%) was most frequently prescribed drug followed by pantoprazole 133 (85.25%) and furosemide 68 (43.58%). Amongst antimicrobials ceftriaxone 51 (32.69%) was the most commonly prescribed drug. Direct cost of treatment per patient for the first 48 h was र 4051 ± 1641.

Conclusion:

Ondansetron and pantoprazole were the most commonly prescribed drugs in the emergency department. However, their use in all patients was not justified. Polypharmacy was prevalent. A closer look at the rationality of therapy would help in highlighting issues involved and would be helpful to authorities in deciding prescribing policies.
