The persistence of serum-specific anti-chikungunya IgM antibodies (CHIKV-IgM) can vary after chikungunya fever (CHIK) infection. However, the factors related to its production are not yet known. We described a case series drawn up from data collected from 57 patients between 12 and 36 months after the acute phase of CHIK infection in Northeastern Brazil. CHIKV-IgM was detectable in 7/57 (12.3%) patients after 28.3 months of infection. No frequency differences in chronic musculoskeletal manifestations and underlying conditions were detected between patients with or without CHIKV-IgM. CHIKV-IgM was detected for up to 35 months in Brazilian patients after CHIK infection.
在感染基孔肯雅热(CHIK)后,血清特异性抗基孔肯雅病毒 IgM 抗体(CHIKV-IgM)的持续存在情况可能有所不同。然而,其产生的相关因素尚不清楚。我们描述了一组病例系列,这些病例是从巴西东北部 CHIK 感染急性期后 12 至 36 个月期间收集的 57 名患者的数据中得出的。在感染 28.3 个月后,7/57(12.3%)名患者可检测到 CHIKV-IgM。在有无 CHIKV-IgM 的患者中,慢性肌肉骨骼表现和基础疾病的发生频率没有差异。在巴西患者中,CHIK 感染后 CHIKV-IgM 可检测长达 35 个月。
