Trans R Soc Trop Med Hyg 2024; 118:1-11. [PMID: 37702193 DOI: 10.1093/trstmh/trad067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 07/25/2023] [Accepted: 08/25/2023] [Indexed: 09/14/2023] Open
Abstract
Numerous studies have shown a correlation between dengue virus (DENV) infection and kidney disease. However, there is no existing meta-analysis on the prevalence of kidney diseases in the dengue population. A thorough systematic review and meta-analysis were undertaken to determine the prevalence of renal problems in people with DENV infection in order to fill this knowledge gap. A rigorous electronic literature search was carried out up to 25 January 2023 in a number of databases, including ProQuest, EBSCOhost, Scopus, PubMed and Web of Science. The search aimed to find articles that reported on the prevalence of kidney diseases in patients with DENV infection. Using the modified Newcastle-Ottawa Scale, the quality of the included studies was assessed. The meta-analysis included a total of 37 studies with 21 764 participants reporting on the prevalence of acute kidney injury (AKI) in individuals with DENV infection. The pooled prevalence of AKI in dengue patients was found to be 8% (95% confidence interval 6 to 11), with high heterogeneity across studies. The studies included are of moderate quality. The study revealed a high AKI prevalence in dengue patients, underlining the need for regular renal examination to detect AKI early and reduce hospitalization risk. Further research is needed to understand the dengue-kidney relationship and develop effective management strategies.

Abstract
Poor-quality medicines are a major threat to healthcare provision in low-income countries. The problem exacerbates disease vulnerabilities of already disadvantaged populations including children, women, and the elderly. However, while the higher-level structural drivers of this problem are well established, little is known about decision-making lower down pharmaceutical supply chains, and whether this might produce vulnerabilities for medicine quality. We conducted a mixed-methods study to explore retailer-supplier interactions and decision-making dynamics for antimalarial medicines in three regions of Tanzania: Tabora, Dodoma and Mbeya. A survey questionnaire was administered to 118 small scale-and mid-range retailers in urban and rural districts of the regions. We then conducted 12 in-depth interviews with staff and owners of medicine outlets in 2 districts of Tabora region to explore further the decision-making dynamics. Results show that private-sector retailers are driven first and foremost by business and economic practicalities when choosing a medicine supplier, prioritising low purchase price, free delivery, and availability of credit. Many also rely on suppliers with whom they have personal connections, developed either within or outside the business context. Medicine quality comes far lower down the list of priorities. These findings are perhaps not surprising in a context where businesses serving low-income customers are operating on very small margins. However, when price and personal connection eclipse any other considerations, there is a risk that poor-quality medicines may find their way into supply chains, especially in countries where regulatory capacity is limited, and pharmaceutical supply chains are complex and opaque.

Abstract
In recent decades, mosquito-borne illnesses have emerged as a major health burden in many tropical regions. These diseases, such as malaria, dengue fever, chikungunya, yellow fever, Zika virus infection, Rift Valley fever, Japanese encephalitis, and West Nile virus infection, are transmitted through the bite of infected mosquitoes. These pathogens have been shown to interfere with the host's immune system through adaptive and innate immune mechanisms, as well as the human circulatory system. Crucial immune checkpoints such as antigen presentation, T cell activation, differentiation, and proinflammatory response play a vital role in the host cell's response to pathogenic infection. Furthermore, these immune evasions have the potential to stimulate the human immune system, resulting in other associated non-communicable diseases. This review aims to advance our understanding of mosquito-borne diseases and the immune evasion mechanisms by associated pathogens. Moreover, it highlights the adverse outcomes of mosquito-borne disease.

Abstract
Dengue viral infections present with a wide clinical spectrum ranging from asymptomatic to severe manifestations with organ involvement. The term "expanded dengue syndrome" has been commonly used to illustrate the unusual or atypical manifestations; acute kidney injury (AKI) is one of the atypical manifestations of this syndrome. The use of heterogeneous criteria to determine the presence of AKI in dengue patients due to the vast diversity in populations led to difficulties in assessing the true incidence of dengue-associated AKI. This review presents a variable, but often high, frequency of dengue-associated AKI among vastly diverse populations with various disease severities. Dengue-associated AKI is not an uncommon complication, and its importance has often been neglected during the management of dengue patients. The risk factors and certain clinical and laboratory findings commonly reported among dengue patients with AKI should be considered to support a timely diagnosis and case management. This review highlights the need for clinicians to be aware of dengue-associated AKI to reduce the morbidity and mortality associated with this common and important tropical disease.

McManus D, Naughton BD. A systematic review of substandard, falsified, unlicensed and unregistered medicine sampling studies: a focus on context, prevalence, and quality. BMJ Glob Health 2020; 5:e002393.

Abstract
Substandard and falsified (SF) medicines are a global issue contributing to antimicrobial resistance and causing economic and humanitarian harm. To direct law enforcement efficiently, halt the spread of SF medicines and antimicrobial resistance, academics, NGOs and government organisations use medicine quality sampling studies to estimate the prevalence of the problem. A systematic review of medicine quality studies was conducted to estimate how the methodological quality of these studies and SF prevalence has changed between 2013 and 2018. We also aimed to critique medicine sampling study methodologies, and the systematic review process which generates prevalence estimates. Based on 33 studies, the overall estimated median (Q1-Q3) prevalence of SF medicines appears to have remained high at 25% (7.7%-34%) compared with 28.5% in 2013. Furthermore, the methodological quality of prevalence studies has improved over the last 25 years. Definitive conclusions regarding the prevalence of SF medicines cannot be drawn due to the variability in sample sizes, consistency of design methods, and a lack of information concerning contextual factors affecting medicine quality studies. We contend that studies which present cumulative average prevalence figures are useful in a broad sense but could be improved to create more reliable estimates. We propose that medicine quality studies record the context of the study environment to allow systematic reviewers to compare like with like. Although, the academic rigour of medicine quality studies is improving, medicine sampling study limitations still exist. These limitations inhibit the accurate estimation of SF medicine prevalence which is needed to support detailed policy changes.

Abstract
Dengue virus (DENV) infections may result in asymptomatic cases or evolve into a severe disease, which involves multiple organ failure. Renal involvement in dengue can be potentially related to an increased mortality. Aiming to better understand the role of DENV in renal injury observed in human fatal cases, post-mortem investigations were performed in four DENV-4 renal autopsies during dengue epidemics in Brazil. Tissues were submitted to histopathology, immunohistochemistry, viral quantification, and characterization of cytokines and inflammatory mediators. Probably due the high viral load, several lesions were observed in the renal tissue, such as diffuse mononuclear infiltration around the glomerulus in the cortical region and in the medullary vessels, hyalinosis arteriolar, lymphocytic infiltrate, increased capsular fibrosis, proximal convoluted tubule (PCT) damage, edema, PCT debris formation, and thickening of the basal vessel membrane. These changes were associated with DENV-4 infection, as confirmed by the presence of DENV-specific NS3 protein, indicative of viral replication. The exacerbated presence of mononuclear cells at several renal tissue sites culminated in the secretion of proinflammatory cytokines and chemokines. Moreover, it can be suggested that the renal tissue injury observed here may have been due to the combination of both high viral load and exacerbated host immune response.

Abstract
Background Flavivirus diseases such as dengue fever (DENV), West Nile virus (WNV), Zika and yellow fever represent a substantial global public health concern. Preexisting chronic conditions such as cardiovascular diseases, diabetes, obesity, and asthma were thought to predict risk of progression to severe infections. Objective We aimed to quantify the frequency of chronic comorbidities in flavivirus diseases to provide an estimate for their prevalence in severe and non-severe infections and examine whether chronic diseases contribute to the increased risk of severe viral expression. Methods We conducted a comprehensive search in PubMed, Ovid MEDLINE(R), Embase and Embase Classic and grey literature databases to identify studies reporting prevalence estimates of comorbidities in flavivirus diseases. Study quality was assessed with the risk of bias tool. Age-adjusted odds ratios (ORs) were estimated for severe infection in the presence of chronic comorbidities. Results We identified 65 studies as eligible for inclusion for DENV (47 studies) and WNV (18 studies). Obesity and overweight (i.e., BMI> 25 kg/m2, prevalence: 24.5%, 95% CI: 18.6–31.6%), hypertension (17.1%, 13.3–21.8%) and diabetes (13.3%, 9.3–18.8%) were the most prevalent comorbidities in DENV. However, hypertension (45.0%, 39.1–51.0%), diabetes (24.7%, 20.2–29.8%) and heart diseases (25.6%, 19.5–32.7%) were the most prevalent in WNV. ORs of severe flavivirus diseases were about 2 to 4 in infected patients with comorbidities such as diabetes, hypertension and heart diseases. The small number of studies in JEV, YFV and Zika did not permit estimating the prevalence of comorbidities in these infections. Conclusion Higher prevalence of chronic comorbidities was found in severe cases of flavivirus diseases compared to non-severe cases. Findings of the present study may guide public health practitioners and clinicians to evaluate infection severity based on the presence of comorbidity, a critical public health measure that may avert severe disease outcome given the current dearth of clear prevention practices for some flavivirus diseases.

Abstract
BACKGROUND Since the introduction of 2009 WHO dengue case classification, no literature was found regarding its effect on dengue death. This study was to evaluate the effect of 2009 WHO dengue case classification towards dengue case fatality rate. METHODS Various databases were used to search relevant articles since 1995. Studies included were cohort and cross-sectional studies, all patients with dengue infection and must report the number of death or case fatality rate. The Joanna Briggs Institute appraisal checklist was used to evaluate the risk of bias of the full-texts. The studies were grouped according to the classification adopted: WHO 1997 and WHO 2009. Meta-regression was employed using a logistic transformation (log-odds) of the case fatality rate. The result of the meta-regression was the adjusted case fatality rate and odds ratio on the explanatory variables. RESULTS A total of 77 studies were included in the meta-regression analysis. The case fatality rate for all studies combined was 1.14% with 95% confidence interval (CI) of 0.82-1.58%. The combined (unadjusted) case fatality rate for 69 studies which adopted WHO 1997 dengue case classification was 1.09% with 95% CI of 0.77-1.55%; and for eight studies with WHO 2009 was 1.62% with 95% CI of 0.64-4.02%. The unadjusted and adjusted odds ratio of case fatality using WHO 2009 dengue case classification was 1.49 (95% CI: 0.52, 4.24) and 0.83 (95% CI: 0.26, 2.63) respectively, compared to WHO 1997 dengue case classification. There was an apparent increase in trend of case fatality rate from the year 1992-2016. Neither was statistically significant. CONCLUSIONS The WHO 2009 dengue case classification might have no effect towards the case fatality rate although the adjusted results indicated a lower case fatality rate. Future studies are required for an update in the meta-regression analysis to confirm the findings.

Abstract
BACKGROUND/PURPOSE Dengue clinically dynamically changes over time; the World Health Organization (WHO) dengue classification framework proposed 3 dengue clinical phases-febrile (days 1-3), critical (days 4-6) and recovery (days ≥7) phases. This study aimed to better understand clinical and laboratory characteristics in adults (≥18 years) suffering dengue in different clinical phases at their hospital presentations. METHODS A retrospective analysis of adults suffering dengue between 2008 and 2014. RESULTS Of the 669 included dengue adults, 146 (21.8%) were elderly (≥65 years), and 27 (4%) suffered severe dengue. When compared with those in febrile phase, significantly higher incidence of ascites, mucosal bleeding, and/or gastrointestinal bleeding; lower white blood cell (WBC) and platelet counts; higher hematocrit, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) values were found in critical phase. When compared with their younger counterparts, elderly at febrile phase had significantly lower frequencies of bone pain, myalgia, headache and rash; higher frequencies of vomiting, pleural effusion and mucosal bleeding; higher WBC count, AST and ALT levels, and lower platelet count; in critical phase, elderly had significantly higher frequencies of pleural effusion, mucosal bleeding and gum bleeding. Four (0.6%) patients experienced severe dengue in recovery phase. Significantly higher proportions of elderly developed severe dengue in both febrile and critical phases as compared with younger adults. CONCLUSIONS Elderly had lower frequency of classical dengue symptoms, yet were at higher risk of development of severe dengue during their early dengue course. A small number of patients developed severe dengue at the WHO-proposed recovery phase.

Abstract
OBJECTIVES Dengue is a mosquito-borne disease caused by arbovirus and well known for its typical fever with thrombocytopenia syndrome. Acute hypokalemic quadriparesis is a rare presentation of dengue with uncertain pathogenesis. We aim to describe the clinical and biochemical characteristics of rapidly resolving weakness related to hypokalemia in patients infected with dengue virus. METHODS A retrospective review of the records of patients with diagnosis of dengue-associated hypokalemic weakness was performed. Demography, clinical, biochemical characteristics, and outcome of the patients were recorded during acute phase of illness. RESULTS Our study cohort comprised 12 patients and all were males from urban dwelling. The median age was 34.5 years (range, 18-50). Presentation was acute onset rapidly worsening pure motor quadriparesis preceded by short lasting febrile episode. Weakness ranged from 2/5 to 4/5 on Medical Research Council (MRC) scale with generalized hyporeflexia or areflexia. The baseline serum potassium was mean ± SD (2.7 ± 0.48 mmol/L). All patients showed elevation of liver transaminases and elevated creatine phosphokinase level. Weakness improved in 24-72 hours in all patients with correction of serum potassium. CONCLUSIONS Dengue-associated acute hypokalemic paralysis is an underrecognized entity having favorable outcome. It should be suspected in patients presenting as acute pure motor quadriparesis after febrile illness in dengue endemic areas.

Abstract
Background The 2009 revised World Health Organization (WHO) guidelines for dengue describe fever as the core symptom. Accordingly, the diagnosis of non-febrile patients is complicated. The aim of this study was to evaluate the importance of fever in patients with dengue according to the 2009 revised WHO classification. Methods In this study, we assessed 30,670 dengue cases using enzyme-linked immunosorbent assay, detection of the non-structural protein 1, or polymerase chain reaction for diagnostic confirmation. Fisher’s exact test was used to evaluate associations between fever and related clinical manifestations. The Mann–Whitney U test was used to assess the association of dengue classification with fever and time to treatment. The effects of fever and time to treatment on the risk of progression were analyzed using an ordinal logistic regression to stereotype the model. Results Disease classification was found to associate significantly with both fever and time to treatment (both P < 0.001). Non-febrile patients were nearly four-fold more likely to exhibit “dengue without warning signs” than “severe dengue” (odds ratio [OR] = 3.74; 95% confidence interval [CI]: 3.20–4.36). Patients who received treatment within 7 days were twice as likely to have “dengue without warning signs” as opposed to “severe dengue” when compared to those who waited >7 days (OR = 2.23; 95% CI: 1.78–2.80). However, this difference was negligible in the multivariate analysis (OR = 1.02; 95% CI: 0.98–1.07). Conclusions Fever is a risk factor for disease progression in patients with dengue. However, non-febrile patients should not be neglected because this may delay treatment and could lead to more severe disease.

Diabetes, cardiac disorders and asthma as risk factors for severe organ involvement among adult dengue patients: A matched case-control study. Sci Rep 2017; 7:39872. [PMID: 28045096 PMCID: PMC5206669 DOI: 10.1038/srep39872] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2016] [Accepted: 11/29/2016] [Indexed: 12/22/2022] Open
Abstract
Progression to severe organ involvement due to dengue infection has been associated with severe dengue disease, intensive care treatment, and mortality. However, there is a lack of understanding of the impact of pre-existing comorbidities and other risk factors of severe organ involvement among dengue adults. The aim of this retrospective case-control study is to characterize and identify risk factors that predispose dengue adults at risk of progression with severe organ involvement. This study involved 174 dengue patients who had progressed with severe organ involvement and 865 dengue patients without severe organ involvement, matched by the year of presentation of the cases, who were admitted to Tan Tock Seng Hospital between year 2005 and 2008. Age group of 60 years or older, diabetes, cardiac disorders, asthma, and having two or more pre-existing comorbidities were independent risk factors of severe organ involvement. Abdominal pain, clinical fluid accumulation, and hematocrit rise and rapid platelet count drop at presentation were significantly associated with severe organ involvement. These risk factors, when validated in a larger study, will be useful for triage by clinicians for prompt monitoring and clinical management at first presentation, to minimize the risk of severe organ involvement and hence, disease severity.

Abstract
Dengue viruses are the most important arboviral pathogens in the world, which have adapted to human transmission and replication over several hundred years and were initially recognized to cause outbreaks of clinical disease in tropical and subtropical countries by Aedes aegypti mosquitoes. Subsequent global expansion of dengue infection outbreaks has occurred, with millions of cases yearly, probably from a combination of factors including proliferation of international travel and trade, possibly global climate changes, adaptation of the vectors to new environment, and emergence of a new mosquito vector, Aedes albopictus. Chikungunya virus, also transmitted by Aedes mosquitoes, causes a very similar clinical disease but with more prominent arthralgia or arthritis and was originally described in Africa in the 1960s. After a quiescent period of several decades, it reemerged in Africa in 2004 and rapidly spread across the Indian Ocean to involve Asian countries and parts of Europe. However, the past 2 years have seen the emergence of chikungunya virus in the western hemisphere with major outbreaks in the Caribbean and the Americas. Similar to dengue virus, chikungunya virus has adapted to Ae. albopictus mosquitoes which can transmit the disease. Although dengue infection is a more deadly disease especially in young children, chikungunya infection can cause prolonged severe disability and occasionally rare fatalities from encephalitis. No specific treatment is available for either diseases, but development of an effective vaccine for dengue infection is in progress. Until 2007, Zika virus [also transmitted by Aedes species] was associated with only sporadic mild infections in Africa and Asia. In 2007, Zika virus for the first time caused an outbreak beyond Africa and Asia to the Yap Island in the Federated States of Micronesia. Since then Zika virus has spread to French Polynesia, New Caledonia, Cook Islands, and Easter Island in the southeastern Pacific Ocean [Chile] in 2014 and by 2015 to Brazil. By January 2016, it became evident that Zika virus had caused an explosive outbreak in the Americas and the Caribbean with over 30 countries affected. On February 1, 2016, the World Health Organization declared Zika outbreak a global public health emergency. Zika virus infection is most commonly asymptomatic, and 20% of patients may develop a mild viral disease, but of major concern is the reported association of microcephaly in infected pregnant women in Brazil. This chapter explores the history, epidemiology, pathogenesis, clinical features, treatment, and prevention of these rapidly emerging zoonoses.

Abstract
Background Some systemic diseases also affect the skeletal muscle to various degrees and with different manifestations. This review aimed at summarizing and discussing recent advances concerning the management of muscle disease in systemic diseases. Method Literature review by search of MEDLINE, and Current Contents with appropriate search terms. Results Secondary muscle disease occurs in infectious disease, endocrine disorders, metabolic disorders, immunological disease, vascular diseases, hematological disorders, and malignancies. Muscle manifestations in these categories include pathogen‐caused myositis, muscle infarction, rhabdomyolysis, myasthenia, immune‐mediated myositis, necrotising myopathy, or vasculitis‐associated myopathy. Muscle affection may concern only a single muscle, a group of muscles, or the entire musculature. Severity of muscle affection may be transient or permanent, may be a minor part of or may dominate the clinical picture, or may be mild or severe, requiring invasive measures including artificial ventilation if the respiratory muscles are additionally involved. Diagnostic work‐up is similar to that of primary myopathies by application of non‐invasive and invasive techniques. Treatment of muscle involvement in systemic diseases is based on elimination of the underlying cause and supportive measures. The prognosis is usually fair if the causative disorder is effectively treatable but can be fatal in single cases if the entire musculature including the respiratory muscles is involved, in case of infection, or in case of severe rhabdomyolysis. Conclusion Secondary muscle manifestations of systemic diseases must be addressed and appropriately managed. Prognosis of secondary muscle disease in systemic diseases is usually fair if the underlying condition is accessible to treatment.

[PMID: 27138448 PMCID: PMC4854400 DOI: 10.1371/journal.pone.0154772] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2015] [Accepted: 04/19/2016] [Indexed: 12/21/2022] Open
Abstract
We aimed to develop and validate a risk score to aid in the early identification of laboratory-confirmed dengue patients at high risk of severe dengue (SD) (i.e. severe plasma leakage with shock or respiratory distress, or severe bleeding or organ impairment). We retrospectively analyzed data of 1184 non-SD patients at hospital presentation and 69 SD patients before SD onset. We fit a logistic regression model using 85% of the population and converted the model coefficients to a numeric risk score. Subsequently, we validated the score using the remaining 15% of patients. Using the derivation cohort, two scoring algorithms for predicting SD were developed: models 1 (dengue illness ≤4 days) and 2 (dengue illness >4 days). In model 1, we identified four variables: age ≥65 years, minor gastrointestinal bleeding, leukocytosis, and platelet count ≥100×109 cells/L. Model 1 (ranging from −2 to +6 points) showed good discrimination between SD and non-SD, with an area under the receiver operating characteristic curve (AUC) of 0.848 (95% confidence interval [CI], 0.771–0.924). The optimal cutoff value for model 1 was 1 point, with a sensitivity and specificity for predicting SD of 70.3% and 90.6%, respectively. In model 2 (ranging from 0 to +3 points), significant predictors were age ≥65 years and leukocytosis. Model 2 showed an AUC of 0.859 (95% CI, 0.756–0.963), with an optimal cutoff value of 1 point (sensitivity, 80.3%; specificity, 85.8%). The median interval from hospital presentation to SD was 1 day. This finding underscores the importance of close monitoring, timely resuscitation of shock including intravenous fluid adjustment and early correction of dengue-related complications to prevent the progressive dengue severity. In the validation data, AUCs of 0.904 (95% CI, 0.825–0.983) and 0.917 (95% CI, 0.833–1.0) in models 1 and 2, respectively, were achieved. The observed SD rates (in both cohorts) were <3% for patients with a score <1 point, but >50% for those with a score of ≥2 points, irrespective of the day of illness onset, suggesting that our simple risk score can be easily implemented in resource-limited countries for early prediction of dengue patients at risk of SD provided that they have rapid dengue confirmed tests. For patients with other acute febrile illnesses or bacterial infections usually have SD risk score of >1. Thus, these scoring algorithms cannot totally replace good clinical judgement of the physician, and most importantly, early differentiating dengue from other febrile illnesses is critical for appropriate monitoring and management.

Abstract
OBJECTIVE To characterize the significance of correlated autoantibodies in systemic lupus erythematosus (SLE) and its complication lupus nephritis (LN) in a large cohort of patients. METHODS Clinical data were statistically analyzed in 1699 SLE patients with or without nephritis who were diagnosed and treated during 2002-2013 in the northeast region of China. Reactivity to a list of 16 autoantibodies was detected by the serum test Euroline ANA profile (IgG). Serum titers of the anti-nucleosome autoantibodies were measured by ELISA assays. Kidney biopsies were examined by pathologists. Immune complex deposition was identified by immunohistochemistry stain. RESULTS Simultaneous positivity of anti-dsDNA, -nucleosome and -histone antibodies (3-pos) was prevalent in SLE patients with LN compared to Non-renal SLE patients (41% vs 11%, p< 0.001). Significant correlations were found between any two of the above three anti-nucleosome antibodies in LN patients. In comparison to non-3-pos cohorts, 3-pos patients with LN had significantly higher serum levels of the three antibodies and more active disease; was associated with type IV disease; suffered from more severe renal damages; received more intensive treatment and had worse disease outcome. The serum levels of these three autoantibodies in 3-pos LN patients were significantly decreased when they underwent clinical recovery. CONCLUSIONS Simultaneous reactivity to anti-dsDNA, -nucleosome and -histone antibodies by Euroline ANA profile (IgG) may indicate severe nephropathy in patients with SLE.

Abstract
BACKGROUND The pathogenesis of Ebola virus disease (EVD) remains unclear. The sporadic nature of Ebola outbreaks and their occurrence in resource-limited settings have precluded the acquisition of extensive clinical and laboratory data. Rhabdomyolysis during EVD has been suggested to occur in previous studies showing increased aspartate aminotransferase-alanine aminotransferase ratios, but, to date, has not been confirmed with creatine kinase (CK) assays. METHODS We performed an observational study of 38 patients admitted to an Ebola treatment center from January to April 2015. CK values from patients with confirmed EVD were compared with those in patients without confirmed EVD. A panel of other analyses were also performed. In patients with EVD, characteristics were compared between survivors and nonsurvivors. RESULTS High levels of CK were more frequent in patients with EVD than in those without (P = .002), and rhabdomyolysis was more frequent (59% vs 19%, respectively; P = .03). CK levels >5000 U/L were observed in 36% of patients with EVD. Also in patients with EVD, fatal outcome was significantly associated with higher creatinine and bilirubin levels, international normalized ratio, and viral load. CONCLUSIONS Rhabdomyolysis is a frequent disorder in EVD and seems to be more common than in other viral infections. It may contribute to the renal failure observed in nonsurviving patients. More studies are needed to determine the impact of rhabdomyolysis on EVD outcome.

Abstract
BACKGROUND Anecdotal reports suggesting that survival rates among hospitalized patients with Ebola virus disease in Guinea are higher than the 29.2% rate observed in the current epidemic in West Africa. METHODS Survival after symptom onset was determined using Kaplan Meier survival methods among patients with confirmed Ebola virus disease treated in Conakry, Guinea from March 25, 2014, to August 5, 2014. We analyzed the relationship between survival and patient factors, including demographics and clinical features. RESULTS Of the 70 patients analyzed [mean age ± standard deviation (SD), 34 ± 14.1; 44 were men], 42 were discharged alive with a survival rate among hospitalized patients of 60% (95% confidence interval, 41.5-78.5%). The survival rate was 28 (71.8%) among 39 patients under 34 years of age, and 14 (46.7%) among 30 patients aged 35 years or greater (p = 0.034). The rates of myalgia (3 of 42 versus 7 of 28, p = 0.036) and hiccups (1 of 42 versus 5 of 28, p = 0.023) were significantly lower among patients who survived. CONCLUSIONS Our results provide insights into a cohort of hospitalized patients with Ebola virus disease in whom survival is prominently higher than seen in other cohorts of hospitalized patients.
