N2 - Sera from adults from an area of Tanzania with high endemicity for Wuchereria bancrofti infection were examined for 4 serological markers of extracellular matrix activity, namely the amino-terminal propeptide of type III procollagen (PIIINP), the carboxy-terminal propeptide of type I procollagen (PICP), the carboxy-terminal telopeptide of type I collagen (ICTP), and hyaluronan. Sera from individuals with non-filarial elephantiasis and from healthy Danes were included as controls. No association was observed between the mean serum concentration of PIIINP or PICP and the clinical, microfilarial or circulating filarial antigen status of the individuals. The mean concentration of ICTP was significantly higher (P < 0.01) in sera from individuals with filarial and non-filarial elephantiasis than in sera from individuals living in filariasis endemic areas but without elephantiasis or in the Danish control sera. Among individuals from the filariasis endemic area, the mean serum concentration of hyaluronan was significantly higher (P < 0.01) in microfilaraemic than in amicrofilaraemic individuals, and significantly higher (P < 0.01) in individuals who had circulating filarial antigens than in those who did not, but there was no relation to the clinical status. The significance of the findings are discussed in relation to the pathological processes taking place in bancroftian filariasis.
