A nail in the coffin of (hydro)chloroquine treatment against COVID-19?

27th May

Chloroquine and it’s analogue hydrochloroquine were proposed as candidate therapeutics against COVID-19, and were one of the drug regiments tested in the World Health Organisation (WHO) Solidarity Trial. However, on the 26th May 2020 the WHO announced the suspension of chloroquine/hydrochloroquine trials for COVID-19.

Chloroquine treatment and COVID-19

14th April

In 2005, after the 2002-3 SARS epidemic researchers demonstrated the in-vivo anti-viral effect of chloroquine in primate cell lines infected with SARS-CoV. These results were further confirmed by Gao et al., Wang et al., & Liu et al.., who also showed inhibitory effects of chloroquine on SARS-CoV-2, the etiological agent of COVID-19.

New insights – drug resistance malaria

05 June 2023

In a recent paper, scientists have discovered a drug resistance mechanism in one of the most dangerous malaria parasites affecting humans…

Molecular mimicry: perfect match propels pathologies

9th October

Molecular mimicry drives the pathogenesis of autoimmune neuropathies such as Guillain-Barré syndrome and multiple sclerosis.Does molecular mimicry also play a role in COVID-19 pathogenesis?

COVID-19 in vitro studies: Use the right cell line

18th August

Hoffman et al., demonstrated that (hydroxy)chloroquine inhibited viral entry in Vero (kidney-derived) cell-lines that did not express TMPRSS2, but had no inhibitory effect on Vero cells-lines that expressed TMPRSS2. Additionally, (hydroxy)chloroquine had limited effect on SARS-CoV-2 entry into TMPRSS2-expressing lung cell-lines.

Indian population could have intrinsic immunity to resist COVID-19 challenge

In a short span of time, COVID-19 has become a rapidly spreading communicable disease forcing the WHO to declare it as the “Public Health Emergency of International Concern” on January 30. As of April 16, the WHO pandemic update indicates a whopping 1,991,562 confirmed reported cases…

SOLIDARITY TRIAL: Testing existing drugs to treat COVID-19

3rd April

In an attempt to avoid repeating the mistakes of the 2014–16 West African Ebola epidemic, where clinical trials were set up late, leading to the under-recruiting of patients – in the current pandemic researchers have decided to start trials as soon as possible…

SOLIDARITY TRIAL: WHO COVID-19 treatment trial

1st April

In an unprecedented effort to obtain scientific data during the SARS-CoV-2 pandemic, the World Health Organization (WHO) has announced the new SOLIDARITY trial that would include thousands of patients from around the world (45 countries and counting)…

Immuno-Ethiopia: Malaria Highlight 2

18th March

Our second highlight is on talks that focused on understanding malaria parasite transmission, motility and emergence of anti-malarial resistance, as well as the neutrophil activity in malaria friend or foe. Prof. Frischknech (Ruprecht-Karis University, Heidelberg) gave a lecture on ‘’Transmission of malaria – from microscopy to experimental vaccine studies’’.

Immune Responses to Vaccination

Immune Response to HIV Vaccine Candidates The most efficacious HIV vaccine candidate to date was the RV144 vaccine run in a trial in Thailand – with 31.5% efficacy. Although the trial showed very modest efficacy, and was based on small numbers, it provided important knowledge towards making a more effective vaccine. Based on the results, Read More
