History

In 1984, van der Meer published the first paper about HIDS, the new "periodic fever" syndrome he had discovered. This was the start of his research on interleukin-1 (IL-1) and his collaboration with Dr.
Charles A. Dinarello Charles A. Dinarello (born April 22, 1943) is a professor of medicine at the University of Colorado at Denver. He is an expert on inflammatory cytokines, specifically Interleukin 1. Education and career Dinarello received his Doctor of Medicine ...
, to find out whether this was an IL-1 disease. In the early 1990s together with his former PhD student Joost PH Drenth, he collected data on HIDS patients in the Netherlands and abroad and characterised the inflammatory response in HIDS (increased IL-1β production of the white blood cells). In 1999, Drenth and van der Meer could establish – together with the group of Dr. Marc Delpech in Paris – that the syndrome was due to mutations of the gene encoding for mevalonate kinase, an enzyme in the cholesterol synthesis pathway. Independently – and at the same time – the group of Professor Ronald Wanders (Amsterdam), also found this genetic defect. Together with Anna Simon and Joost Drenth he established that HIDS should be considered an auto-inflammatory syndrome. Some 5 years ago, his group discovered that recombinant interleukin-1 receptor antagonist (IL-1RA, anakinra) is effective as a treatment for HIDS. This finding not only provides patients with an effective therapy, but also provides further proof that HIDS is an interleukin-1 disease. Since 1987, van der Meer worked on the role of cytokines in health and inflammatory disease. The work started in Boston and was continued in Nijmegen. In the years to follow, Bart-Jan Kullberg (1992), Mihai Netea (1994) and Leo AB Joosten (2007) joined the group. Major findings of the group are: * Interleukin-1 (IL-1) stimulates host defence against infection through interference with lethal cytokinaemia * Hyperlipoproteinaemia defends the host against Gram-negative bacterial infection, but not against fungal infection. *

As a clinician confronted with patients with chronic fatigue syndrome (CFS), van der Meer was intrigued by their suffering. Since 1989 together with Gijs Bleijenberg and Jochem MD Galama, he performed research trying to understand CFS. Major findings are: * There is no evidence for a role of persistent infection (such as enteroviral infection,

Concerned about the increasing antimicrobial resistance in the world, he was one of the founders (and first chairman) of the Dutch working group on antibiotic policy, SWAB, which receives long-term support from the Ministry of Health in the Netherlands. At the European level, he was a co-founder and first chairman of the ESGAP (ESCMID study group on antimicrobial policy). Since 1990, van der Meer is involved with biomedical research development and capacity building in Indonesia (first in Semarang, later in Jakarta and Bandung). In 2004, together with Andre JAM van der Ven, he took the initiative to establish PRIOR (Poverty Related Infection Oriented Research), a virtual collaborative centre in which research groups in Jakarta and Bandung in Indonesia (Professor Sangkot Marzuki), KCMC Moshi, Tanzania (Professor Shao), Nijmegen (Professor AJAM van der Ven), Leiden (Professor Tom Ottenhoff), Maastricht (Professor Harm Hospers), RIVM Bilthoven (Professor Dick van Soolingen), and Wageningen (Professor Clive West †) work together in the combat of poverty-related infections (especially HIV infection and tuberculosis).
