Adverse Drug Reactions and Prescription Patterns of Antiretroviral Drugs: A Longitudinal Observational Study From a Tertiary Care Hospital in Western India

Background In 2018, the World Health Organisation (WHO) released interim guidelines, advising a change of regimens to dolutegravir-based first- and second-line antiretroviral therapy (ART), based on which, in 2021, the National Aids Control Organisation (NACO) updated its guidelines to include the tenofovir + lamivudine + dolutegravir (TLD) regimen as a first line of therapy for all people living with HIV (PLHIV) and second- and third-line regimens to dolutegravir-based regimens. Considering this change of regimen, the adverse drug reaction (ADR) profiling and longitudinal prescription pattern of antiretroviral and concomitant medications in adult patients at the ART centre of a tertiary care hospital were assessed in this study. Methods Ninety-seven PLHIV out of all the patients who attended the ART centre from September 2021 to July 2022 were enrolled and followed up for six months. The ADRs that occurred during this period were collected along with details of prescription patterns and analyzed by descriptive statistics. Causality assessment for ADR was done using the World Health Organisation-Uppsala Monitoring Centre (WHO-UMC) scale. Results Seventy-eight percent (n=76 out of 97) of patients experienced at least one ADR, and 128 ADRs were seen in 97 patients. The most common ADRs were increased alkaline phosphatase (39.0%, n=128), dyslipidaemia (12.5%, n=128), and nephrotoxicity (10.1%, n=128). The drug most suspected of causing ADRs was dolutegravir (27.5%, n=342). The most common therapeutic regimen was TLD (71.2%, n=97). The most prescribed drug was lamivudine (30.6%, n=1183). The most prescribed concomitant medication was cotrimoxazole (15%, n=312). Conclusions Dolutegravir-based regimens have been implemented for PLHIV in a phased-out manner from previous non-dolutegravir-based ART regimens, which is in line with the recent NACO guidelines. However, it has also led to an increase in dolutegravir-associated ADRs like increased alkaline phosphatase, dyslipidaemia, and nephrotoxicity. Continuous monitoring of prescriptions and ADRs can add to our knowledge regarding their use and ADRs.

Investigator knowledge, awareness, and registrations of academic clinical trials with the Clinical Trial Registry of India: An observational study

Introduction

In 2019, the Central Drugs Standard Control Organization (CDSCO) introduced the New Drugs and Clinical Trials Rules 2019 (NDCTR), which separated the research guidelines for "Clinical Trials" and "Biomedical and Health Research." As a result, guidelines issued by Indian Council of Medical Research were stated to apply to academic clinical trials (ACTs). This change is important because academic studies are crucial for scientific advancement and repurposing of approved drugs in health-care industry. However, conducting an ACT can pose challenges. We assessed the level of awareness, knowledge, and challenges faced by investigators. Our aim is to overcome some of these challenges and encourage more academic studies for the betterment of healthcare and scientific knowledge in India.

Methodology

The study was conducted in two phases after obtaining approval from the Institutional Ethics Committee (EC) of three tertiary care hospitals in Mumbai. In the first phase, the number of ACTs was assessed from the clinical trial registry India website, while the number of registered and re-registered ECs were assessed from the CDSCO website. The second phase involved assessing investigator awareness and knowledge about ACTs using a prevalidated questionnaire with a content validity index score of 0.93.

Results

In 2020, the highest numbers of studies were registered, with the highest numbers of registered and re-registered ECs from Maharashtra. All participants completed the questionnaire and were aware of the need to follow guidelines for clinical trials. Sixty-seven percent of participants knew that the guidelines for ACTs differed from those of sponsored clinical trials, but only 58% were aware of the exact definition of an ACT as per NDCTR, 2019. Eighty-five percent of participants knew who could initiate an ACT, but only 27% knew about the applicability of results of an ACT and 33% had in-depth knowledge about the required approvals, while only 10% knew the archival period. Although 71% of participants had knowledge about serious adverse event reporting, few answered in-depth questions correctly. Only 31 participants reported facing varied challenges.

Conclusion

To conduct ACTs effectively and contribute to healthcare and scientific advancement, it is crucial to enhance investigators' existing knowledge about ACTs.
