Malaria: the dramatic failure of mass drug administration

January 21, 2022 - 15:21 -- Pierre Lutgen

Against the malaria pandemia mass drug administration (MDA) of chloroquine, methylene blue, atabrine, pyrimethamine, mefloquine… was a component of many programs during the eradication era. It is far from a success story. The failure of chloroquine MDA is well known. Twenty years ago all these drugs were replaced by ACTs (artemisinin combined therapy).

What is MESA Track?

January 18, 2022 - 17:13 -- MESA Alliance

"What is MESA Track?" describes the MESA Track online platform, an open and living database of malaria research. This user-friendly and open-access tool informs the malaria community about which questions are being addressed, which innovative strategies are being tested, and aids collaboration and information-sharing.

New link between sickle cell and severe malaria found

January 4, 2022 - 09:40 -- Malaria World

31.12.2021 - SciDev.Net

Malaria parasites may have adapted so that they can cause severe malaria in people with sickle cell disease, a study suggests.

Sickle cell, a group of conditions which can cause red blood cells to become sickle shaped, is become common in Africa because the genes responsible for the disease can help prevent malaria during early childhood, according to the World Health Organization (WHO).

Concealed Erythrocytic Parasites and Elimination of Plasmodium vivax

December 22, 2021 - 22:53 -- Miles Markus

In the malaria research field, prior events are sometimes overlooked (or ignored). Being formerly of a mild disposition (not always entirely so now, if provoked by displays of poor ethics), thirty years elapsed before I drew attention to one of these events. An analogy is that when you tread on the tail of a dinosaur, there can be a long delay before it turns its head.

Artemisia afra, pancreas, diabetes

December 16, 2021 - 17:00 -- Pierre Lutgen

A few years ago, whilst running the clinical trials against malaria and bilharzia with Artemisia plants in Maniema, RDCongo, Dr. Jerome Munyangi noticed that these plants had cured or alleviated the diabetes of several patients.

     Munyangi J, Idumbo M, Mupenda B, Lutgen P. Five case reports on treatment of diabetes by Artemisia annua and Artemisia afra herbal tea. Pharm Pharmacol. Int J. 2020; 8(2):79‒85. DOI: 10.15406/ppij.2020.08.00283

This finding was recently confirmed by a case study in Burundi (see annex 1).

All you need to know about... the MESA Deep Dives

December 14, 2021 - 12:06 -- MESA Alliance

What are the Deep Dives?

The Deep Dives show -as far as possible- the state of the art of the main malaria research topics. Taking MESA Track as the information source, the Deep Dives gather all the projects around a specific research question and classify them according to research areas, timelines and geographic locations. The Deep Dives also include information on funding sources, principal institutions and principal investigators.

WHO: Malaria diagnosis - Addressing the issue of HRP2 gene deletions

December 13, 2021 - 17:49 -- Malaria World

Access to an accurate and timely diagnosis is critical to preventing a malaria infection from progressing to severe illness and death. WHO recommends prompt malaria diagnosis either through microscopy or rapid diagnostic tests (RDTs) for all patients with suspected malaria. The hundreds of millions of RDTs sold each year are designed to detect a specific protein in a person’s blood. Parasites that have mutated to no longer express that protein can evade detection by RDTs.

WHO Report - State of inequality: HIV, tuberculosis and malaria

December 9, 2021 - 20:29 -- Malaria World

This report is the first systematic global analysis of the state of inequality in HIV, TB and malaria. Drawing from two decades of global data about for a range of disease indicators and multiple dimensions of inequality, it aims to facilitate a broad understanding of inequalities in HIV, TB and malaria.

The state of inequality analysis assesses the latest situation of inequality (2011–2020), and shows how this compares to the previous decade (2001–2010). For each disease, analyses are contextualized within the current state of knowledge from the broader literature, including information about key and underserved populations. The report examines the implications of the findings, featuring examples of approaches to address unfair and remediable inequalities and opportunities for strengthening inequality monitoring. Additional resources accompany the report, including interactive visuals and data.

Can P. vivax sporozoites having the same genotype be both tachysporozoites and bradysporozoites?

December 2, 2021 - 01:13 -- Miles Markus

Lysenko et al.’s hypothetical P. vivax tachysporozoites [1] multiply in the liver soon after inoculation into the host, whereas their hypothetical bradysporozoites form hypnozoites [1], which are the origin of relapses. This "tachy" and "brady" terminology is an extension of usage unrelated to malaria [2].

Homologous P. vivax malarial recurrences are not necessarily relapses

November 26, 2021 - 10:29 -- Miles Markus

It was pointed out a decade ago that non-reinfection recurrences of Plasmodium vivax malaria caused by parasites that are closely related to those from an earlier time point are highly suggestive of a merozoite origin [1,2].

This would make them recrudescences (in an unknown proportion of cases), not relapses. In other words, hypnozoites [3] have nothing to do with such a recurrence.

Some recurrences that take place after 28 days post infection are also recrudescences (not relapses), as has recently been explained [2].

Artemisia afra irreversibly cures tuberculosis

November 16, 2021 - 21:19 -- Pierre Lutgen

Early this year we published the results of 15 case studies. In 2020 15 patients infected by tuberculosis had been cured after 3 weeks of administration of Artemisia afra infusions, alone or in combination with the WHO prescribed drugs.

      Daddy B, Lutgen P, Gisenya P. Breakthrough against tuberculosis: high efficacy of Artemisia afra infusions. Pharm Pharmacol Int J. 2021;9(2):58‒62.

Meanwhile in several countries of the Great Lakes, the tuberculosis of some 30 additional patients has been cured, mostly by Artemisia afra alone.
