Destructive arthritis in a patient with chikungunya virus infection with persistent specific IgM antibodies

Abstract: Background: Chikungunya fever is an emerging arboviral disease characterized by an algoeruptive syndrome, inflammatory polyarthralgias, or tenosynovitis that can last for months to years. Up to now, the pathophysiology of the chronic stage is poorly understood.

“…Following the 2005-2006 epidemic in Indian Ocean islands, radiographic evidence emerged of bone pathologies similar to those in rheumatoid arthritis (RA) in CHIKV-infected patients (5,6). Recently, bone pathologies in joints of CHIKV patients have been reported, providing clinical evidence that alphaviruses may also affect skeletal health (7).…”

“…Persistent CHIKV infection also has been observed for weeks to months in experimentally infected mice (137,147) and NHPs (105,163), with vRNA detected in joint tissue (150), muscle, and spleen (105). In addition, persistent IgM levels have been detected in patients and animals experiencing chronic arthritis (8,105,126,153,164,165). These data suggest that persistent CHIKV antigen, or perhaps infection, in protected cellular reservoirs triggers inflammation that culminates in chronic CHIKV rheumatic disease (Figure 3).…”

“…19 Viral or antigen persistence also has been suggested as a possible mechanism for the prolonged production of IgM antibodies seen with other viruses, such as chikungunya, Japanese encephalitis, and rubella. [20][21][22] A third possible explanation for prolonged IgM antibody synthesis is an incomplete class switching either caused by alterations in the vaccine virus because of the attenuation process or potential interference of the vaccine virus in the regulation or recognition of molecules needed for class switching. 23,24 Finally, subsequent exposure to YF virus or a related flavivirus could have caused IgM antibodies to persist or reform after infection.…”
