Abstract
BACKGROUND Little is known about the etiology, clinical presentation, management, and outcome of central nervous system (CNS) infections in Indonesia, a country with a high burden of infectious diseases and a rising prevalence of HIV. METHODS We included adult patients with suspected CNS infections at two referral hospitals in a prospective cohort between April 2019 and December 2021. Clinical, laboratory, and radiological assessments were standardized. We recorded initial and final diagnoses, treatments, and outcomes during 6 months of follow-up. RESULTS Of 1051 patients screened, 793 were diagnosed with a CNS infection. Patients (median age 33 years, 62% male, 38% HIV-infected) presented a median of 14 days (IQR 7-30) after symptom onset, often with altered consciousness (63%), motor deficits (73%), and seizures (21%). Among HIV-uninfected patients, CNS tuberculosis (TB) was most common (60%), while viral (8%) and bacterial (4%) disease were uncommon. Among HIV-infected patients, cerebral toxoplasmosis (41%) was most common, followed by CNS TB (19%), neurosyphilis (15%), and cryptococcal meningitis (10%). A microbiologically confirmed diagnosis was achieved in 25% of cases, and initial diagnoses were revised in 46% of cases. In-hospital mortality was 30%, and at six months, 45% of patients had died, and 12% suffered from severe disability. Six-month mortality was associated with older age, HIV, and severe clinical, radiological and CSF markers at presentation. CONCLUSION CNS infections in Indonesia are characterized by late presentation, severe disease, frequent HIV coinfection, low microbiological confirmation and high mortality. These findings highlight the need for earlier disease recognition, faster and more accurate diagnosis, and optimized treatment, coupled with wider efforts to improve the uptake of HIV services.

Abstract
Central nervous system (CNS) viral infections are critical causes of morbidity and mortality in children; however, comprehensive data on etiology is lacking in developing countries such as Indonesia. To study the etiology of CNS infections in a pediatric population, 50 children admitted to two hospitals in Bandung, West Java, during 2017-2018 were enrolled in a CNS infection study. Cerebrospinal fluid and serum specimens were tested using molecular, serological, and virus isolation platforms for a number of viral and bacteriological agents. Causal pathogens were identified in 10 out of 50 (20%) and included cytomegalovirus (n = 4), Streptococcus pneumoniae (n = 2), tuberculosis (n = 2), Salmonella serotype Typhi (n = 1) and dengue virus (n = 1). Our study highlights the importance of using a wide range of molecular and serological detection methods to identify CNS pathogens, as well as the challenges of establishing the etiology of CNS infections in pediatric populations of countries with limited laboratory capacity.

Abstract
Introduction. Viral infections are increasingly an important cause of central nervous system (CNS) complications.
Hypothesis/Gap Statement. There is no comprehensive insight about CNS infections due to viral agents among Iranian children.
Aim. This study aimed to investigate the viral aetiology, clinical and epidemiological profile of children with acute infections of the CNS.
Methodology. A prospective study was conducted on children at the referral hospital in Isfahan, Iran, from June 2019 to June 2020. A multiplex PCR assay was used to detect the viral causative agent in cerebrospinal fluid and throat/rectal swab samples.
Results. Among 103 patients with eligible criteria, a confirmed or probable viral aetiology was detected in 41 (39.8 %) patients, including enteroviruses – 56.1 %, herpes simplex virus 1/2 (HSV-1/2) – 31.7 %, Epstein-Barr virus – 17.1 %, varicella-zoster virus (VZV) – 9.7 %, influenza A virus (H1N1) –4.9 % and mumps – 2.4 %. There was a higher proportion of PCR-positive samples in infants than in other age groups. Encephalitis and meningoencephalitis were diagnosed in 68.3 % (28/41) and 22 % (9/41) PCR-positive cases, respectively.
Conclusion. The findings of this research provide insights into the clinical and viral aetiological patterns of acute CNS infections in Iran, and the importance of molecular methods to identify CNS viruses. HSV and VZV were identified as important causes of encephalitis in young children.

Abstract
Chikungunya virus (CHIKV) is recognized but rarely considered as a cause of central nervous system infection in endemic areas. A total of 244 patients with acute meningoencephalitis in Indonesia were retrospectively tested to identify whether any CHIKV infection was associated with neurological manifestations, especially in provinces known for CHIKV endemicity. Cerebrospinal fluid (CSF) and blood specimens were tested using CHIKV-specific real-time reverse transcription polymerase chain reaction and IgM ELISA, alongside a panel of neurotropic viruses. We report four cases of suspected or confirmed CHIKV-associated neurological disease, including CHIKV RNA detection in CSF of one patient and in acute serum of another, and CHIKV IgM in CSF of three patients and in serum of a fourth. In conclusion, CHIKV should be considered as a cause of neurologic disease in endemic areas and especially during outbreaks, in addition to the more common arboviral diseases such as dengue and Japanese encephalitis viruses.

Abstract
INTRODUCTION: Herpesviruses, enteroviruses, and arboviruses are important because of their clinical relevance and ability to cause meningitis, encephalitis, meningoencephalitis, and other diseases. The clinical virology associated with diagnostic technologies can reduce the morbidity and mortality of such neurological manifestations. Here we aimed to identify the genomes of agents that cause neurological syndromes in cerebrospinal fluid (CSF) samples from patients with suspected nervous system infections admitted to the University Hospital of the University of Campinas, São Paulo, Brazil, in 2017-2018. METHODS: CSF samples collected from adult patients with neurological syndrome symptoms and negative CSF culture results were analyzed using polymerase chain reaction (PCR), reverse transcriptase-PCR, and real-time PCR, and their results were compared with their clinical symptoms. One CSF sample was obtained from each patient. RESULTS: Viral genomes were detected in 148/420 (35.2%) CSF samples: one of 148 (0.2%) was positive for herpes simplex virus-1; two (0.5%) for herpes simplex virus-2; eight (1.9%) for varicella-zoster virus; four (1%) for Epstein-Barr virus; one (0.2%) for cytomegalovirus; 32 (7.6%) for human herpesvirus-6; 30 (7.1%) for non-polio enterovirus; 67 (16.0%) for dengue virus, three (0.7%) for yellow fever virus, and 21 (5%) for Zika virus. CONCLUSIONS: The viral genomes were found in 35.2% of all analyzed samples, showing the high prevalence of viruses in the nervous system and the importance of using a nucleic acid amplification test to detect viral agents in CSF samples.

Abstract
Central nervous system involvement of dengue virus is increasingly reported from endemic areas. This study describes the clinical characteristics and laboratory features of a pediatric patient enrolled in a central nervous system illness study conducted in 2017-2018 to identify viral and bacterial etiologies in Indonesian children. Dengue diagnostics including molecular and serological testing were performed on an encephalitis patient who presented with both classical dengue and neurological clinical symptoms. Dengue virus serotype 1 RNA was detected in both cerebrospinal fluid and serum by serotype-specific reverse transcription polymerase chain reaction, and the E gene was successfully sequenced. Anti-dengue virus immunoglobulin M was detected in both admission and discharge sera, whereas anti-dengue virus immunoglobulin G was identified only in the discharge serum. This study describes the central nervous system complications in a case with dengue virus infection in West Java, Indonesia, and highlights the potential for dengue virus serotype 1, a serotype rarely associated with neurotropism, to cause encephalitis.

Abstract
BACKGROUND Survivors of childhood encephalitis often suffer from physical and neurocognitive sequelae, particularly in tropical, resource-limited areas with a large burden of arboviral, neurotropic pathogens and limited resources with which to address chronic morbidities. Research into overall and pathogen-specific outcomes following childhood encephalitis may help identify risk factors for poor outcomes, quantify the burden of sequelae, assist with resource allocation and help focus rehabilitative efforts. However, such research is limited. To this end, we systematically reviewed the literature on this topic to identify gaps in knowledge worthy of future investigation. METHODS A search of PubMed, Web of Knowledge and the Cochrane databases was performed 10 January through 20 February 2020, using 17 search terms for sequelae and 14 for tropical, arboviral pathogens. Eligible reports demonstrated post-discharge follow-up of ≥3 months and assessment of clinical outcome in a child with an arboviral encephalitis ≤18 years of age at diagnosis. RESULTS Of 1513 articles, 35 were eligible, comprising 693 children. Japanese encephalitis accounted for 18 articles and 93.2% of all subjects (646 total). Sequelae were documented in ∼60% of subjects overall and in those with Japanese encephalitis. For non-Japanese encephalitis virus encephalitides (47 children), sequelae were found in 78.1%. No studies utilized comprehensive neurocognitive testing or assessed the efficacy of rehabilitative efforts. Only nine studies reported data from ≥1 follow-up visit. CONCLUSION Investigation into long-term outcomes following tropical childhood encephalitis is limited, particularly for neurocognitive sequelae, serial assessments over time and the effect of rehabilitative measures. LAY SUMMARY Encephalitis, an infection of the brain, is frequently caused by arboviruses (viruses spread via the bite of infected arthropods, such as mosquitoes) in tropical locales. Following infection, surviving children may be plagued with severe physical and cognitive deficits. Unfortunately, research into the type of deficits, their frequency and their responsiveness to rehabilitative efforts is lacking. We identified and reviewed 35 studies describing outcomes in children recovering from tropical, arboviral encephalitis at least 3 months following hospital discharge. Poor outcomes were common and found in up to 60% of children. Long-term and serial follow-up visits were rare, as was the use of comprehensive neurocognitive testing. No studies assessed the efficacy of rehabilitative measures. Further study into these areas is recommended.

Abstract
BACKGROUND Viruses are a common cause of central nervous system (CNS) infections. However, studies of CNS viral pathogens in pediatric patients are poorly explored because viral infections are often erroneously diagnosed as bacterial infections. METHODS 299 CNS samples were collected from pediatric patients aged from one month to 14 years old. A total of 140 viral meningitis cases that met the inclusion criteria were included in this study. In 38 of the 140 cerebral spinal fluid (CSF) samples (27.1%), conventional and real-time PCR were used to identify viruses commonly associated with CNS infections. RESULTS Among them, 23 patients (16.5%) tested positive for flaviviruses such as dengue, Zika, and yellow fever virus, eight patients (5.7%) were positive for enterovirus (ENTV), and six patients (4.3%) were positive for human herpesvirus 1/2. We also identified one case of dengue virus and ENTV co-infection. CONCLUSIONS A correlation between clinical symptoms and laboratory findings for the viruses was identified. Our study also reinforces the importance of including viruses in the laboratory diagnosis of CNS infections especially flaviviruses, which assists public health authorities in implementing early interventions.

[PMID: 33167379 PMCID: PMC7663808 DOI: 10.3390/ijms21218281] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 09/17/2020] [Accepted: 09/19/2020] [Indexed: 12/20/2022] Open
Abstract
The goal of the study was to develop a specific, sensitive, and cost-effective molecular RT-PCR diagnostic assay for the rapid and simultaneous detection of the serotypes of dengue virus (DENV) and Chikungunya virus (CHIKV) from sera of suspected febrile patients. A single-tube, single-step multiplex RT-PCR (mRT-PCR) assay was designed for the detection of viral genomes from clinical and field samples. Specificity and sensitivity of the mRT-PCR assay were evaluated against six different combinations using two reverse transcriptases (AMV-RT and RT-Ace) and three DNA polymerases (LA-Taq, rTaq, and Tth). Among the six combinations, the AMV-RT and LA-Taq combination was more specific and sensitive than other enzyme combinations for detecting viral genomes of DENV-1, DENV-2, DENV-3, and DENV-4 (p < 0.01), and for detecting viral genomes of CHIKV (p < 0.05). The detection limits of the mRT-PCR were 10 focus forming units (FFU) for CHIKV and 1 FFU, 20 FFU, 0.1 FFU, and 10 FFU for DENV-1, DENV-2, DENV-3, and DENV-4, respectively. The primers used for the mRT-PCR did not show any cross-reactivity among the serotypes of DENV or CHIKV. Specificity and sensitivity of the newly developed mRT-PCR were validated using serum samples collected from febrile patients during dengue outbreaks in Bangladesh. The sensitivity for serotype detection of DENV and CHIKV was superior to the virus isolation method and the antigen detection method using the Dengue NS1-Ag assay. This novel mRT-PCR method can be used for molecular epidemiological surveillance of DENV and CHIKV in epidemic and endemic countries.

Spatial epidemiology of Japanese encephalitis virus and other infections of the central nervous system infections in Lao PDR (2003-2011): A retrospective analysis. PLoS Negl Trop Dis 2020; 14:e0008333. [PMID: 32453806 PMCID: PMC7274481 DOI: 10.1371/journal.pntd.0008333] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 06/05/2020] [Accepted: 04/28/2020] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Central nervous system (CNS) infections are important contributors to morbidity and mortality and the causative agents for ~50% patients are never identified. The causative agents of some CNS infections have distinct spatial and temporal patterns. METHODOLOGY/PRINCIPAL FINDINGS Here we present the results of a spatial epidemiological and ecological analysis of CNS infections in Lao PDR (2003-2011). The data came from hospitalizations for suspected CNS infection at Mahosot Hospital in Vientiane. Out of 1,065 patients, 450 were assigned a confirmed diagnosis. While many communities in Lao PDR are in rural and remote locations, most patients in these data came from villages along major roads. Japanese encephalitis virus ((JEV); n = 94) and Cryptococcus spp. (n = 70) were the most common infections. JEV infections peaked in the rainy season and JEV patients came from villages with higher surface flooding during the same month as admission. JEV infections were spatially dispersed throughout rural areas and were most common in children. Cryptococcus spp. infections clustered near Vientiane (an urban area) and among adults. CONCLUSIONS/SIGNIFICANCE The spatial and temporal patterns identified in this analysis are related to complex environmental, social, and geographic factors. For example, JEV infected patients came from locations with environmental conditions (surface water) that are suitable to support larger mosquito vector populations. Most patients in these data came from villages that are near major roads; likely the result of geographic and financial access to healthcare and also indicating that CNS diseases are underestimated in the region (especially from more remote areas). As Lao PDR is undergoing major developmental and environmental changes, the space-time distributions of the causative agents of CNS infection will also likely change. There is a major need for increased diagnostic abilities; increased access to healthcare, especially for rural populations; and for increased surveillance throughout the nation.

Abstract
Zika virus (ZIKV) has recently been confirmed as endemic in Indonesia, but no congenital anomalies (CA) related to ZIKV infection have been reported. We performed molecular and serological testing for ZIKV and other flaviviruses on cord serum and urine samples collected in October 2016 to April 2017 during a prospective, cross-sectional study of neonates in Jakarta, Indonesia. Of a total of 429 neonates, 53 had CA, including 14 with microcephaly. These 53, and 113 neonate controls without evidence of CA, were tested by ZIKV-specific real-time reverse transcription polymerase chain reaction (RT-PCR), pan-flavivirus RT-PCR, anti-ZIKV and anti-DENV IgM ELISA, and plaque reduction neutralization test. There was no evidence of ZIKV infection among neonates in either the CA or non-CA cohorts, except in three cases with low titers of anti-ZIKV neutralizing antibodies. Further routine evaluation throughout Indonesia of pregnant women and their newborns for exposure to ZIKV should be a high priority for determining risk.

Rickettsia felis identified in two fatal cases of acute meningoencephalitis. PLoS Negl Trop Dis 2020; 14:e0007893.

Abstract
BACKGROUND Rickettsia felis has recently emerged worldwide as a cause of human illness. Typically causing mild, undifferentiated fever, it has been implicated in several cases of non-fatal neurological disease in Mexico and Sweden. Its distribution and pathogenicity in Southeast Asia is poorly understood. METHODOLOGY/PRINCIPAL FINDINGS We retroactively tested cerebrospinal fluid (CSF) or sera from 64 adult patients admitted to hospital in North Sulawesi, Indonesia with acute neurological disease. Rickettsia felis DNA was identified in the CSF of two fatal cases of meningoencephalitis using multi-locus sequence typing semi-nested PCR followed by Sanger sequencing. DNA from both cases had 100% sequence homologies to the R. felis reference strain URRWXCal2 for the 17-kDa and ompB genes, and 99.91% to gltA. CONCLUSION/SIGNIFICANCE The identification of R. felis in the CSF of two fatal cases of meningoencephalitis in Indonesia suggests the distribution and pathogenicity of this emerging vector-borne bacteria might be greater than generally recognized. Typically Rickettsia are susceptible to the tetracyclines and greater knowledge of R. felis endemicity in Indonesia should lead to better management of some acute neurological cases.

Predictive Role of Electroencephalography in Regard to Neurological and Cognitive Sequelae After Acute Central Nervous System Infection. Acta Inform Med 2019; 27:234-239. [PMID: 32055089 PMCID: PMC7004286 DOI: 10.5455/aim.2019.27.234-239] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/29/2022] Open
Abstract
Introduction: Electroencephalography can also be used to monitor long-term recovery of the patient after acute phase of the disease. Impaired neurocognitive function after infection, similar to brain injury, may present a transient but also prolonged problem for the functioning of an individual. Some studies have shown that importance of EEG may not be significant in sequel monitoring, because the extensive changes in EEG seen with severe forms of CNS infection do not necessarily imply a longer-term poor outcome. Aim: To examine the predictive potential of electroencephalography (EEG) in regard to the emergence of neurological and cognitive sequelae of acute central nervous system (CNS) infection. Methods: The study included 62 patients treated at the Clinic for Infectious Diseases, Clinical Center of Sarajevo University, who were diagnosed with acute CNS infection. The EEG record was characterized as: normal, non-specific changes of mild, moderate and severe degree and specific changes. The sequelae (headache, cognitive dysfunction, neurological and neurophysiological disorders, audiological and behavioral disorders) was evaluated by combining neurological, psychiatric, pediatric, otolaryngological, ophthalmic and infectological examination in the Neuroinfective Counseling Department for up to 6 months after discharge. Results: After a treatment of an acute CNS infection 25 (40.3%) patients had no sequelae and 37 (59.7%) were with sequelae. The EEG in the initial stage of the disease (Wald’s coefficient = 12.8), followed by the age of the patients (Wald = 6.4), had the greatest influence on the prediction of sequela (p=0.0001). For each additional degree of verified pathological changes in the EEG, the risk of sequelae was increased by 5 degrees (OR = 5.3), respectively. There was no statistically significant association between changes in cerebrospinal fluid (CSF) findings, meningeal symptoms, and signs with sequelae development. Conclusion: Younger age, as well as severe clinical status of a patient, which implies a disorder of consciousness and seizures on admission, are associated with irreversible consequences on a previously mentally healthy individual. Pathological changes (Delta and Theta waves, spike slow complex wave) on the EEG finding significantly predicted presence of sequelae. .
