A retrospective examination was made of archival data on 98 patient episodes of infection with Plasmodium vivax occurring over a period of 4-11 weeks to document changes in hemoglobin (Hb) concentrations associated with continuing parasitemia. The mean percentage change in the Hb concentration for each of the 10 seven-day intervals was -13.4, -10.9, -4.8, 0.12, 0.94, 4.0, 0.69, 11.6, 2.4, and 8.3, respectively. An equilibrium appeared to be established between weeks 4 and 6. Decreases in Hb concentrations were greatest following the first week of parasitemia. Total restoration to preinfection levels did not occur during persistent parasitemia.
对98例间日疟原虫感染患者病程长达4 - 11周的档案数据进行回顾性检查，以记录与持续寄生虫血症相关的血红蛋白（Hb）浓度变化。在10个为期7天的时间段内，Hb浓度的平均百分比变化分别为-13.4、-10.9、-4.8、0.12、0.94、4.0、0.69、11.6、2.4和8.3。在第4周和第6周之间似乎建立了平衡。寄生虫血症第一周后Hb浓度下降最为明显。在持续寄生虫血症期间，Hb浓度并未完全恢复到感染前水平。
