These are:

  • Malaria with the ICMR-NIMR in New Delhi

  • Visceral leishmaniasis with the ICMR and the Rajendra Memorial Research Institute of Medical Sciences (ICMR-RMRIMS) in Patna

  • Lymphatic filariasis with the ICMR and the Vector Control Research Centre (ICMR-VCRC) in Puducherry

Researchers have been developing their skills in key areas like data collection, storage and management; modelling; clinical trials and public health. Below several of the researchers discuss their experience taking part in the ICMR-NIMR and IDDO collaboration and the new skills they have acquired during the training.

 

I joined the ICMR-NIMR-IDDO project to utilize my skills and expertise of clinical trials in exploring various infectious disease. The training activities in all the modules were conducted in depth. All the resources like databases, materials, documents were provided effectively and in a timely manner. These training schedules have widened my capabilities some of them being preparation of protocol, designing of case report forms for a clinical trial, scoping and searching various databases, creating appropriate search strategies that can help in future trial designing and planning.

 – Dr Beauty Behera, Clinical Research Manager, ICMR-NIMR-IDDO

 

My motivation behind joining this project was to get trained in applying the huge amount of available data to identify knowledge gaps that will inform future research priorities in malaria. This training is a great learning experience, and it introduced me to different skills related to data in malaria research, clinical trials, and public health.

– Dr Reena Verma, Consultant, ICMR-NIMR-IDDO

 

Research is a vast field, and it is ever-growing. Joining the ICMR-NIMR-IDDO training suited my need to grow my skills and also provided an opportunity to work with the leading international researchers in the field of Malaria. It has been an amazing experience and the skills that I have acquired during this training will go a long way to help me grow professionally even more, and expand my knowledge horizon.

– Dr Sundus Ahmad, Consultant, ICMR-NIMR-IDDO

 

Being from the molecular biology background, joining the ICMR-NIMR-IDDO joint project seemed to me as a wonderful opportunity to widen my horizon and explore new avenues. The training was quite thorough and detailed, and I learned the basics of data collection, storage and management which are the pillars for every field of research and will help me to systematically design and execute my research plans.

 – Dr Minu Nain, Consultant, ICMR-NIMR-IDDO

 

My main motivation to join the IDDO-NIMR-ICMR training was to enhance the knowledge and open a new door of research on Infectious diseases like Malaria, visceral leishmaniasis, and lymphatic filariasis. The training modules were comprehensive and included detailed sessions on Systematic Review Meta-Analysis, REDCap and Covidence softwares which would be very useful for my future research plans.

– Dr Azhar Uddin, Consultant,  ICMR-VCRC-IDDO

 

I have recently joined the ICMR-NIMR-IDDO joint project with an aim to learn more about the emerging issues in malaria research, and the approaches that we could adopt to address these issues.

– Dr Pushpender Kumar, Consultant, ICMR-NIMR-IDDO

 

Being a PhD in Bioinformatics and with six months of working experience in construction, maintenance, analysis, etc. of celiac disease biorepository at AIIMS Delhi, I wanted to further explore new horizons in public and clinical health, and this was my motivation behind joining the ICMR-NIMR-IDDO joint project. During the training, I got an opportunity to learn from the pioneers of the respective fields. Currently, I am learning Geospatial modelling from the IDDO team and I am also engaged with the IDDO informatics team to learn about WWARN Data Manager and WWARN surveyors.

Estimating the proportion of relapse following treatment of Visceral Leishmaniasis: Meta-analysis of published studies

A meta-analysis aimed at estimating the proportion of relapse during the study follow-up period following treatment of Visceral Leishmaniasis (VL)

Women at meeting
Timeline

Analysis is ongoing with expected completion of the research activity by March-2022. Publication is expected by mid-2022 and dissemination of results will follow.

Rationale

Visceral Leishmaniasis (VL) is a vector-borne disease transmitted by sandflies and caused by protozoan parasites of the genus Leishmania. An estimated 50,000 to 90,000 new cases of VL occur worldwide annually. The disease is fatal if untreated. The ultimate endpoint of parasitological efficacy is defined as the absence of relapse within the follow-up period after achieving initial cure upon the completion of treatment. Most clinical efficacy studies adopt a 6-month follow-up post-treatment to capture relapsing cases. Relapses after 6 months have been reported in observational cohorts leading to suggestion that a longer follow-up period may be warranted [1].

Objectives

This project aims to quantify the proportion of relapses observed in VL patients at 6 and 12 months of follow-up after treatment with an antileishmanial drug. The specific objectives are:

  1. To estimate the proportion of relapses observed in VL clinical trials stratified by drug regimen, geographical region, follow-up duration, and mg/kg drug dosage administered
  2. To estimate the proportion of relapses captured at 6-months and at 12-months in studies with a follow-up duration longer than 6 months
Inclusion criteria for studies

This research will utilise data from the studies indexed in the IDDO VL living systematic review of all published clinical studies.

The following inclusion criteria is adopted:

  1. Studies with at least 6 months of post-treatment follow-up period
  2. Studies that aimed to capture relapse during the post-treatment follow-up period

The following studies will be excluded

  1. Studies with unclear information regarding the follow-up duration
  2. Studies not reporting the number of patients who were initially cured
  3. Studies that enrolled patients with HIV co-infection
Data extraction and analysis

Data on the following aspects of the included studies were extracted: study design, location, publication year, age range of the participants, total number of participants enrolled including the number of patients achieving initial cure, relapse. When reported, the number of the patients with these outcomes were extracted for each of the following time-interval: within 6 months of post-treatment follow-up, between 6-12 months or after 1 year of follow-up. The proportion of patients with relapse will be combined using random effects meta-analysis after applying logit transformation. The pooled estimates will be presented together with the associated 95% confidence intervals (95% CIs) and sub-group meta-analyses will be undertaken to explore potential sources of heterogeneity.

Our work

IDDO is working with the visceral leishmaniasis (VL) research community to collate global data and deliver robust science to address knowledge gaps and save lives with better treatment. The platform aims to facilitate pooled analysis of individual patient data (IPD) to answer the research questions of key interest to the VL research community.

A living systematic review

IDDO has found that data exists on more than 35,000 patients enrolled in over 150 trials in the past 20 years. This is captured in the VL Surveyor, an interactive tool that maps VL clinical trials and provides a clear visualisation of the research landscape.

This scattered but rich resource informs knowledge gaps in treatment optimisation that could influence future research. However, usually only summary statistics are available from publications, with results often not reported in a standardised and statistically comparable manner across different trials. This makes comparative analysis of efficacy between drugs, regimens and regions almost impossible. 

A harmonised database of VL clinical trials

IDDO has assembled a harmonised database of VL clinical trials containing over 14,000 IPD, representing nearly one-third of the published sample size. Study groups investigating key research questions using the combined IPD have been launched in collaboration with data contributors and research experts.

Case report form for uncomplicated VL

In collaboration with the VL research community and partners including DNDi, IDDO has developed a freely-available case report form annotated to CDISC standards for uncomplicated VL. The case report form provides a flexible standard for use by VL researchers in clinical trial research.

Study groups

IDDO facilitates collaborative Study Groups to undertake individual patient data meta-analyses to answer specific research questions about visceral leishmaniasis (VL) treatments.  Working together, and combining data from different regions and populations, is improving our understanding of the disease, and will advance research and subsequent drug development.

Systematic reviews

Our global collaborations have produced systematic reviews investigating critical areas of concern surrounding VL treatment and clinical trial research.

Open call to join new studies launched by the VL research community

Two new Study Groups, a collaboration between IDDO and the global visceral leishmaniasis (VL) research community, have been formed to answer specific research questions about treatments. They will undertake individual patient data meta-analyses using datasets from multiple studies, across sub-populations of interest, to help explore sources of between-study heterogeneity in therapeutic responses. Colleagues from across the VL research community are invited to join.

Group of children

One Group will explore Anaemia among patients with VL and haematological dynamics post treatment and aim to characterise the haematological parameters at baseline and during the initial treatment and in the ensuing follow-up period using individual participant data hosted at IDDO VL data platform.

The other will look at Host, parasite, and drug determinants of therapeutic responses. There is a marked regional heterogeneity in therapeutic response against antileishmanial therapies in VL. Single dose Liposomal Amphotericin B remains the current first line therapy in the Indian subcontinent due to the emergence and evolution of drug resistant parasites against pentavalent antinomy (PA). However, PA in combination with Paromomycin has demonstrated a high efficacy in Africa and continues to be used as a first line therapy. Such heterogeneity in therapeutic responses has been thought to arise due to regional differences in parasite sensitivity/susceptibility. The importance of host and drug parameters as a determinant of observed differences in clinical response demand further investigations.

Both Study Groups will be co-led by Dr Prabin Dahal and Dr Sauman Singh. Colleagues from the VL research community interested in joining the Study Groups should email vl@iddo.org for more information.

Prabin Dahal, one of the study co-leads remarked: “Individual participant data (IPD) meta-analysis is increasingly recognised as a gold-standard method for evidence synthesis. It allows a more thorough and flexible analysis to be undertaken that would otherwise not be possible through published aggregate data. For example, the number of relapses in any single trials are few. Pooling IPD from several studies would allow us to explore the host, parasite and drug determinants of relapses which can be used to inform optimal case management. These study groups are therefore a unique opportunity for the global VL community to answer some of the long standing questions related to disease and the drugs.“

VL, also known as kala-azar, is transmitted to humans through the bites from infected female phlebotomine sand flies. If left untreated, it is fatal in 95% of cases. Globally, it is estimated there are up to 22,000 new cases of VL each year which occur in Brazil, Ethiopia, India, Kenya, Somalia, South Sudan and Sudan.

IDDO is a scientifically independent, multi-disciplinary coalition of the global infectious disease community. It is unique among data-sharing initiatives in taking many different types of data and standardising these to create larger-scale datasets to enable global research collaborations to pose new scientific questions.
