RESUMO

OBJECTIVES: To assess the prevalence of acute kidney injury (AKI), and its impact on outcome in hospitalized pediatric patients with Lassa fever (LF). METHODS: We reviewed the presenting clinical and laboratory features and outcomes of 40 successive hospitalized children with PCR-confirmed LF. The diagnosis and staging of AKI was based on KDIGO criteria. We compared groups of patients using t- or χ2 tests as necessary, and took p-values <0.05 as indicative of the presence of significant differences. RESULTS: Sixteen (40%) children had AKI. Case fatality rate (CFR) was 9/16 (56%) in children with and 1/24 (4%) in those without AKI (OR [95% CI] of CFR associated with AKI = 29.57 [3.17, 275.7]). Presentation with abnormal bleeding (p = 0.008), encephalopathy (p = 0.004), hematuria plus proteinuria (p = 0.013), and elevated serum transaminase levels (p <0.02) were significantly associated with an increased prevalence of AKI. CONCLUSION: AKI prevalence in hospitalized pediatric patients with Lassa fever is high, and correlated with illness severity/CFR. The high prevalence underscores the need for access to hemodialysis, and clinical presentation and/or presence of hematuria plus proteinuria could serve as a ready prompt for referral for such specialized care.

RESUMO

Few reports on the prevalence of acute abdomen (AAbd) in pediatric patients with Lassa fever (LF) are available, and no firm policy on its management exists. Here, we report on its prevalence in and the response to treatment among a cohort of children with confirmed LF. Six (10.3%) of 58 children with LF had AAbd, whereas 6 (2.8%) of 215 children with AAbd had LF. Nonoperative treatment was successful in 5 of the 6 children with both AAbd and LF. We conclude that AAbd is not uncommon in pediatric patients with LF, and it could be responsive to nonoperative treatment. Testing for LF in all children with febrile AAbd might be justified in areas in which LF is endemic.

RESUMO

Background: The general lack of comprehensive data on the trends of Lassa fever (LF) outbreaks contrasts with its widespread occurrence in West Africa and is an important constraint in the design of effective control measures. We reviewed the contribution of LF to admissions and mortality among hospitalized patients from 2001 to 2018 in the bid to address this gap. Methods: Observational study of LF caseload and mortality from 2001 to 18 in terms of the contribution of confirmed LF to admissions and deaths, and case fatality (CF) among patients with confirmed LF at a specialist center in Nigeria. The diagnosis of LF was confirmed using reverse transcription polymerase chain reaction (RT-PCR) test, and medians and frequencies were compared using Kruskal-Wallis, Mann-Whitney and χ2 tests, with p-values <0.05 taken as significant. Results: The contribution of confirmed LF to deaths (362/9057, 4.0%) was significantly higher than to admissions (1,298/185,707, 0.7%; OR [95% CI] = 5.9 [5.3, 6.7], p < 0.001). The average CF among patients with confirmed LF declined from 154/355 (43%) in 2001-09 to 183/867 (21.1%) (OR [95% CI] = 2.9 [2.2, 3.7], p < 0.001) in 2011-18. The annual CF declined from 94% in 2001 to 15% in 2018 whereas the caseload increased from 0.3 to 3.4%. The outbreaks were characterized by irregular cycles of high caseload in 2005-2007, 2012-2014, and 2016-2018, and progressive blurring of the seasonality. Conclusion: LF outbreaks in Nigeria have upgraded spatially and temporally, with the potential for cycles of increasing severity. The strategic establishment of LF surveillance and clinical case management centers could be a pragmatic and cost-effective approach to mitigating the outbreaks, particularly in reducing the associated CF. Urgent efforts are needed in reinvigorating extant control measures while the search for sustainable solutions continues.

RESUMO

The Lassa virus is known to cause disease in different organ systems of the human body, with varying clinical manifestations. The features of severe clinical disease may include bleeding and/or central nervous system manifestations. Whereas Lassa fever encephalopathy and encephalitis are well described in the literature, there is paucity of data on Lassa virus meningitis. We present the clinical description, laboratory diagnosis, and management of 4 consecutive cases of aseptic meningitis associated with Lassa virus infection without bleeding seen in a region of Nigeria known to be endemic for both the reservoir rodent and Lassa fever. The 4 patients recovered fully following intravenous ribavirin treatment and suffered no neurologic complications.
