RESUMO

Cytomegalovirus is the most common cause of congenital infection worldwide. 90 % of children infected in utero are born without symptoms, but 15 % of them will develop disorders within the first five years of life. The most common disorders affect the inner ear, resulting in sensorineural hearing loss and/or vestibular dysfunction (VD). VD is often unrecognized and confused with conditions -affecting the central nervous system. It can cause delays in psychomotor development and predispose to overall developmental delay. Early diagnosis and treatment are essential to prevent or limit these sequelae. Antiviral treatment during the pre- and neonatal periods should be considered.


Le cytomégalovirus est la cause la plus fréquente d'infection congénitale dans le monde. 90 % des enfants infectés in utero naissent sans symptôme, mais 15 % d'entre eux vont développer des atteintes au cours des cinq premières années de vie. Les plus fréquentes touchent l'oreille interne, engendrant une­surdité neurosensorielle et/ou une dysfonction vestibulaire (DV). La DV est souvent méconnue et confondue avec des atteintes du système nerveux central. Elle peut provoquer des retards du ­développement psychomoteur et prédisposer à un retard global du développement. Un diagnostic et une prise en charge précoces sont essentiels pour prévenir ou limiter ces séquelles. Un traitement antiviral en période pré et néonatale doit être considéré.

RESUMO

Objective: To explore the disease spectrum and corresponding clinical indicators of infantile cholestasis so as to provide a basis for the diagnosis of this type of disease at an early stage. Methods: The clinical data was collected from 203 hospitalized children diagnosed with infantile cholestasis at the Department of Gastroenterology of Maternal and Child Health Care, Guiyang City, from January 2018 to March 2023, including 130 males and 73 females. Patients general condition, personal history, and blood biochemical test indicators, including liver and coagulation function, blood ammonia, blood lipid profile, blood sugar, TORCH, thyroid function, and others, were retrospectively analyzed after admission. Cholangiography and high-throughput gene sequencing were performed in certain patients. The etiology of the enrolled cases were analyzed. Children's clinical data were compared with distinct inherited metabolic liver diseases (Group A) and biliary atresia (Group B). The statistical analysis was conducted using the t-test, Mann-Whitney test, Kruskal-Wallis test, or χ2 test, according to different data. Results: In 33 cases, infectious factors-primarily CMV infection-were the etiology of cholestasis. Forty cases had aberrant bile duct development, primarily biliary atresia, choledochal cysts, and intrahepatic bile duct dysplasia. In 26 cases, genetic metabolic factors mainly included citrin protein deficiency, sodium-taurocholate co-transporting polypeptide deficiency, and Alagille syndrome. 11 cases had drug/poisoning factors (parenteral nutrition-associated cholestasis). 19 cases had idiopathic infantile cholestasis. Three cases had other factors; however, all of them had Kawasaki disease. 71 cases had an unclear diagnosis. There was no statistically significant difference in terms of gender and age between groups A and B (P>0.05). The alkaline phosphatase (ALP) and bile acid levels were significantly higher in Group A than Group B, with a P<0.05, while the gamma glutamyltransferase (GGT), direct bilirubin (DBil), and albumin levels were lower than those in Group B, with a P<0.05. The cytomegalovirus infection rate was higher in Group B (62.50%) than Group A (34.62%), and the difference between the two groups was statistically significant (χ2=3.89, P<0.05). The alanine aminotransferase, aspartate aminotransferase, GGT, DBil, and albumin were significantly lower in patients with citrin protein deficiency than those in patients with biliary atresia, while ALP, bile acid, and blood ammonia were higher than those in patients with biliary atresia. Patients with sodium-taurocholate co-transporting polypeptide deficiency had higher bile acid than patients with biliary atresia, while the DBil was lower than that in patients with biliary atresia, and the difference was statistically significant (P<0.05). Conclusion: Infantile cholestasis etiology is diverse. ALP, bile acids, GGT, DBil, and albumin levels can serve as simple indicators for early-stage differentiation between inherited metabolic liver disease and biliary atresia. The cholestasis etiology should be determined as early as possible following biliary atresia exclusion by actively completing genetic metabolic gene detection.

RESUMO

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a complex and potentially fatal hypersensitivity condition. We present a unique case report and literature review focusing on DRESS syndrome-associated myocarditis resulting from reactivated viral infections in a 21-year-old female. 3 weeks after 5-day oral co-trimoxazole consumption due to acne, she developed symptoms consistent with DRESS syndrome, including a generalized maculopapular rash. Despite prednisolone treatment, the patient developed fatal fulminant myocarditis linked to HHV-6 and CMV reactivation. The patient's death highlights the importance of early recognition and careful management of DRESS syndrome, especially considering the potential viral reactivation that can lead to severe complications. Postmortem investigations revealed that viral reactivation caused myocarditis. Careful consideration must be given to corticosteroid usage in DRESS treatment, as inappropriate prescribing may promote viral reactivation and subsequent complications. While high-dose corticosteroids initiated within the first week effectively suppress HHV-6 reactivation. Conversely, low-dose or late-start high-dose corticosteroids prove ineffective in preventing HHV-6 viremia. Late- onset or low- dose corticosteroids may lead to fatal complications following the primary viral reactivation.

RESUMO

OBJECTIVE: Congenital cytomegalovirus infection (cCMV) is a common, frequently unrecognized cause of childhood disability. The aim of the present study was to determine the symptoms that raise the suspicion of cCMV, define the neurodevelopmental outcomes, and assess their correlations. METHODS: This longitudinal observational study comprised 78 children with symptomatic cCMV who underwent neuropediatric follow-up for 4 to 17.9 years. RESULTS: Symptoms of central nervous system involvement, hearing/visual impairments, and hepatic involvement were mostly recognized. The average age of disease suspicion was 3.3 months. In terms of outcomes, 10.53% of the children developed complex minor neurological dysfunction and 23.68% developed cerebral palsy. Visual and hearing impairments occurred in 38.16% and 14.47% of patients, respectively. Intellectual disability was present in 30.26% of patients, and epilepsy in 21.05%. Microcephaly and hearing impairment was significantly associated with overall neurodevelopmental outcome. Microcephaly was also associated with poor motor outcomes, hearing impairment, and severe visual impairment. Furthermore, microcephaly and intrauterine growth restriction were significantly associated with poor cognitive outcomes. CONCLUSION: Symptoms that raised the suspicion of cCMV-especially microcephaly, hearing impairment, and intrauterine growth restriction-were important parameters that were associated with outcomes; however, their recognition was often insufficient and/or late.

RESUMO

SUMMARY: Cytomegalovirus (CMV) is known to cause fatal pneumonia in human immunodeficiency virus (HIV) infected children. There is a paucity of literature on pediatric HIV and CMV coinfection in India. We describe six cases of severe pneumonia in infants infected with HIV. Four of these infants also had CMV coinfection, detected by urine polymerase chain reaction. There was a lack of antenatal and postnatal care in all cases. All four infants with CMV coinfection succumbed to severe acute respiratory distress syndrome, whereas the other two survived. In conclusion, a high index of suspicion for CMV should be kept in HIV-infected infants presenting with severe pneumonia, although CMV pneumonia is difficult to diagnose with certainty. The important role of antenatal care for mothers with HIV infection, as well as postnatal care for babies born to HIV-positive mothers, cannot be overstated.

RESUMO

Cytomegalovirus (CMV) is a pathogen that is common worldwide and is often present in individuals infected with human immunodeficiency virus (HIV). Pattern recognition receptors (PRRs) are host sensors that activate the immune response against infectious agents. However, it is unclear whether PRR single-nucleotide polymorphisms (SNPs) are associated with the occurrence of CMV DNAemia in subjects coinfected with HIV and CMV. HIV/CMV-coinfected patients with and without CMV DNAemia were recruited for this study. The DDX58 rs10813831 and IFIH1 (rs3747517 and rs1990760) polymorphisms were genotyped using the TaqMan Allelic Discrimination Assay, whereas the DDX58 rs12006123 and TLR3 (rs3775291 and rs3775296) SNPs were analyzed using a polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay. A mutation present in at least one allele of the DDX58 rs12006123 SNP occurred at least two times more frequently in HIV/CMV-coinfected patients with CMV DNAemia than in coinfected subjects without CMV DNAemia (OR, 2.50; 95% CI, 1.33-4.68; p = 0.004, in the dominant model). A higher level of CMV DNAemia was observed in subjects who had the heterozygous (GA) or homozygous recessive (AA) genotype for the DDX58 rs12006123 SNP compared with those who had the wild-type (GG) genotype (p = 0.0003). Moreover, in subjects with a mutation detected in at least one allele of the DDX58 rs12006123 SNP, a lower serum IFN-ß concentration was found compared with those who had a wild-type (GG) genotype for this polymorphism (p = 0.024). The DDX58 rs12006123 SNP is associated with CMV DNAemia in HIV/CMV-coinfected patients.

RESUMO

BACKGROUNDCongenital cytomegalovirus (cCMV) infection can cause developmental impairment and sensorineural hearing loss (SNHL). To determine the relationship between immune responses to cCMV infection and neurologic sequelae, T cell responses were compared for their connection to clinical symptoms at birth and neurodevelopmental outcomes.METHODSThirty cCMV-infected and 15 uninfected infants were enrolled in a single-center prospective observational case-control study. T cell pp65-specific cytokine responses; CD57, CD28, and PD-1 expression; and memory subsets were compared.RESULTSInfected neonates (73% symptomatic at birth) lacked pp65-specific cytokine-secreting T cells, with elevated frequencies of CD57+, CD28-, and PD-1+CD8+ T cells and effector memory subsets. Though frequencies overlapped between cCMV symptom groups, asymptomatic infants had higher frequencies of CD57+PD-1+CD8+ T cells. Neonates with subsequent developmental delay lacked detectable CMV-specific T cell responses, with patterns resembling those of uninfected infants. Two children with progressive SNHL had high frequencies of PD-1+CD8+ T cells over the first year compared with children without progressive SNHL.CONCLUSIONSimilar to published reports, neonatal viral antigen-specific cytokine-secreting T cell responses were not detected, but overall patterns indicate that globally differentiated memory CD8+ T cell populations were induced by cCMV infection, with higher frequencies of terminally differentiated PD-1+CD8+ T cells potentially associated with asymptomatic infection. In this cohort, a lack of in utero T cell differentiation was associated with developmental delay, and high frequencies of PD-1+CD8+ T cells persisted only in children with progressive SNHL. Further work is needed to define the specificity of these T cells and their mechanistic connection to these outcomes.FUNDINGThis study was funded through an intramural research award at Nationwide Children's Hospital, the Pediatric Infectious Disease Society Fellowship Award funded by Stanley and Susan Plotkin and Sanofi Pasteur, the Abigail Wexner Research Institute at Nationwide Children's Hospital, and the Pichichero Family Foundation Vaccines for Children Initiative Research Award from the Pediatric Infectious Diseases Society Foundation.

RESUMO

BACKGROUND/AIM: The mortality rate for alimentary tract hemorrhage remains high due to a variety of contributing factors. In this report, we present a case of post-severe trauma patient with life-threatening gastrointestinal bleeding caused by cytomegalovirus (CMV)-induced damage to the terminal ileum. CASE REPORT: A 76-year-old female with a history of hypertension and gastrointestinal bleeding developed CMV ileitis post-severe trauma. Despite negative CMV IgM antibodies, PCR testing confirmed CMV infection in the biopsy tissue. Histopathological examination revealed viral inclusion bodies, with immunohistochemistry confirming CMV presence. RESULTS: Intravenous ganciclovir effectively managed symptoms and halted bleeding. CMV ileitis, typically seen in immunocompromised states, may occur sporadically in immunocompetent individuals, including post-orthopedic surgery patients. The exact mechanism remains unclear, possibly related to surgical stress. Diagnosis relies on histopathology and immunohistochemistry. CONCLUSION: Early recognition and treatment are vital for optimal outcomes, emphasizing the need for awareness among orthopedic surgeons regarding CMV as a potential cause of postoperative complications.

RESUMO

OBJECTIVES: Congenital Cytomegalovirus (cCMV) has been associated with hearing, vision, and neurodevelopmental long-term sequelae. Despite the social burden associated with the disease, a universally accepted consensus on screening, diagnostic, therapeutic and follow-up approaches has not been reached. The present observational retrospective study aims at describing long-term sequelae and radiological abnormalities associated with cCMV in children early identified by extended hearing-targeted screening and evaluated by audiological follow-up in a single III Level Audiological Referral Center for at least 2 years. METHODS: Audiological neonatal and follow-up data were available for all subjects. Data collection included clinical neonatal and virological assessment at birth. Ophthalmological, neurodevelopmental and neuroradiological follow-up abnormalities compatible with cCMV sequelae were collected by clinical reports. Spearman's rank correlation coefficient (rho-ρ) was used to evaluate possible correlations among the considered parameters. RESULTS: 61 newborns were identified by extended hearing-targeted cCMV screening and diagnosed mostly (83.6 %) by PCR viral DNA extraction in urine collected within the 15° day of life. Seventeen babies were born preterm, with a mean gestational age of 33.5 weeks. Sixteen patients (26.2 %) were admitted to an Intensive or sub-Intensive Neonatal Care Unit. At birth, 35 newborns were symptomatic (57.3 %), and 19 of them received antiviral treatment by valganciclovir or ganciclovir. Overall, 20 children (32.7 %) were diagnosed with sensorineural hearing loss (SNHL), among them 17 (85 %) were refer at the newborn hearing screening while 3 (15 %) were Pass. 5/20 children (25 %) presented isolated SNHL, while in 15/20 (75 %) children SNHL was associated to other long-term sequelae. In 5 patients (25 %) a progression of the hearing threshold was observed, with a mean age of progression of 26 months of age. Risk factors for progression were a worse final hearing threshold (Spearman's ρ = 0.434; p = 0.0001) and a worse hearing threshold at birth (Spearman's ρ = 0.298; p = 0.020). Thirteen children were fitted with hearing aids, 8 of whom subsequently underwent cochlear implantation. Concerning long term impairments, 10/61 children (17 %) presented a variety of ophthalmological sequelae, while 16/40 cCMV patients (40 %) were diagnosed with neurodevelopmental abnormalities. Language delays were significantly associated with a worse hearing threshold (ρ = 0.582; p = 0.0001) and with other neurocognitive abnormalities (ρ = 0.677, p = 0.0001). 30 children underwent radiological brain evaluation by Magnetic Resonance Imaging, and 63.3 % of them presented abnormalities compatible with cCMV. Mean viral load at birth did not show significant associations with long-term sequelae. CONCLUSIONS: The study highlights the diverse and significant long-term sequelae of cCMV infection detected through early screening. With a significant proportion of cCMV children developing sensorineural hearing loss, ophthalmological and neurodevelopmental issues, the results emphasize the importance of continuous, multidisciplinary follow-up. Early identification and tailored interventions are crucial for improving the long-term health and quality of life of children affected by cCMV.

RESUMO

PURPOSE OF REVIEW: The purpose of this review is to summarize the very recent literature surrounding hearing outcomes of children with congenital cytomegalovirus (cCMV) detected through systematic screening programs. RECENT FINDINGS: There are several different approaches to cCMV screening including forms of targeted vs. universal screening of newborns as well as maternally-derived prenatal testing. However, many studies fail to document hearing-related outcomes both in the newborn period and further into childhood when late-onset sensorineural hearing loss (SNHL) can occur. This systematic review included studies of neonates screened for cCMV reporting hearing outcomes for at least one point in time. Hearing targeted screening appeared the most widely reported for detection of unilateral and bilateral SNHL in those with cCMV. A few studies examined these clinical findings in relation to antiviral treatment. SUMMARY: Congenital CMV is an important and common cause of childhood hearing loss. Newborn screening programs may expand opportunities for early diagnosis and treatment of the infection and its sequelae.

RESUMO

BACKGROUND: There are still many patients newly diagnosed with HIV at an advanced stage in Indonesia. We aimed to identify factors associated with 1-year mortality among cytomegalovirus (CMV)-infected people living with HIV (PLHIV). METHODS: This retrospective cohort study was carried out at a tertiary-care hospital in Jakarta, Indonesia (January 2017 to December 2022). We included PLHIV with CMV end-organ disease (EOD) and CMV syndrome. The presence of CMV infection was confirmed by fulfilling one of the following criteria: (1) positive PCR from plasma, urine, cerebrospinal fluid, or other body fluids, or associated tissue for CMV EOD; (2) positive immunoglobulin M (IgM); or (3) consistent symptoms and signs of CMV retinitis. RESULTS: Out of 1737 PLHIV, 147 (8.5%, 95% CI: 7.2 to 9.9%) were diagnosed with CMV infection. Forty (27.2%, 95% CI: 20.6 to 35.1%) patients died within 1 year of being diagnosed. Only anti-retroviral therapy (ART) defaulting (aHR 3.31, 95% CI: 1.12 to 9.73) was found to be significantly associated with 1-year mortality in multivariate analysis. CONCLUSION: Defaulted ART status is significantly associated with reduced 1-year survival after CMV infection diagnosis. Patients with low CD4 counts, especially those with <50 cells/µL, should be assessed for CMV infection, monitored, and treated accordingly.

RESUMO

INTRODUCTION: This prospective cohort study aims to investigate the hearing dynamics and the changes in the central auditory pathways in infants with congenital cytomegalovirus (cCMV) infection. MATERIALS AND METHODS: cCMV-infected neonates aged ≤3 weeks old were recruited and underwent clinical and laboratory tests to detect viremia and symptomatic infection, hearing examinations at three and six months of age, and radiological imaging of brain auditory pathways using diffusion tensor imaging. RESULTS: From 26 eligible infants (52 ears), we detected symptomatic infection in nine (34.6%), viremia in 14 (14/25; 56.0%) and sensorineural hearing loss (SNHL) in 14 infants (53.8%). We observed 40 ears (76.9%) with unstable hearing thresholds, 17 (42.5%) of which fluctuated. Hearing fluctuation and progressivity were more common in symptomatic infection (66.7% vs. 14.7%, p<0.001; and 38.9% vs. 2.9%, p=0.002; respectively). A substantial proportion of ears had reduced fractional anisotropy (FA) in the medial geniculate body (59.1%), superior olivary nucleus (45.5%), trapezoid body (40.9%), auditory radiation (36.4%) and inferior colliculus (31.8%). Symptomatic infection was associated with an increased FA in the medial geniculate body (mean difference, MD: 0.12; 95% Confidence Intervals, 95%CI: 0.03, 0.22) and viremia in the inferior colliculus (MD: 0.09; 95%CI: 0.02, 0.16). An FA in the inferior colliculus of ≥0.404 had a sensitivity and specificity of 68.8% and 83.3% in predicting viremia (area under the curve 0.823; 95%CI: 0.633, 1.000, p=0.022). CONCLUSION: SNHL along with its fluctuation and progression are common in cCMV-infected infants. cCMV infection may induce structural changes in the central auditory pathway.

RESUMO

BACKGROUND: The role of cytomegalovirus infection as an opportunistic pathogen in exacerbating ulcerative colitis and its response to treatment remain a topic of ongoing debate. Clinicians encounter numerous challenges, including the criteria for differentiating between an acute ulcerative colitis flare and true cytomegalovirus colitis, the diagnostic tests for identifying cytomegalovirus colitis, and determining the appropriate timing for initiating antiviral therapy. CASE PRESENTATION: A 28-year-old Syrian female with a seven-year history of pancolitis presented with worsening bloody diarrhea, abdominal pain, and tenesmus despite ongoing treatment with azathioprine, mesalazine, and prednisolone. She experienced a new flare of acute severe ulcerative colitis despite recently completing two induction doses of infliximab (5 mg/kg) initiated four weeks prior for moderate-to-severe ulcerative colitis. She had no prior surgical history. Her symptoms included watery, bloody diarrhea occurring nine to ten times per day, abdominal pain, and tenesmus. Initial laboratory tests indicated anemia, leukocytosis, elevated C-reactive protein (CRP) and fecal calprotectin levels, and positive CMV IgG. Stool cultures, Clostridium difficile toxin, testing for Escherichia coli and Cryptosporidium, and microscopy for ova and parasites were all negative. Sigmoidoscopy revealed numerous prominent erythematous area with spontaneous bleeding. Biopsies demonstrated CMV inclusions confirmed by immunohistochemistry, although prior biopsies were negative. We tapered prednisolone and azathioprine and initiated ganciclovir at 5 mg/kg for ten days, followed by valganciclovir at 450 mg twice daily for three weeks. After one month, she showed marked improvement, with CRP and fecal calprotectin levels returning to normal. She scored one point on the partial Mayo score. The third induction dose of infliximab was administered on schedule, and azathioprine was resumed. CONCLUSION: Concurrent cytomegalovirus infection in patients with inflammatory bowel disease presents a significant clinical challenge due to its associated morbidity and mortality. Diagnosing and managing this condition is particularly difficult, especially regarding the initiation or continuation of immunosuppressive therapies.

RESUMO

BACKGROUND: Road traffic injuries (RTIs) are among the most important issues worldwide. Several studies reported that infection with the neurotropic parasite Toxoplasma gondii (T. gondii) increased the risk of car accidents. In this study, our objective was to investigate the possible associations among latent T. gondii, Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV) infections with the risk of motorcycle accidents in Jahrom (Fars Province), which is a county with a high rate of motorcycle accidents in Iran. METHODS: In the setting of a case-control study; 176 motorcyclist men, including 88 survivors of motorcycle accidents and 88 motorcyclist without accidents, were considered as case and control groups, respectively. Rates of latent infections with T. gondii, CMV, and HSV were assessed by an enzyme-linked immunosorbent assay (ELISA). RESULTS: Eleven of 88 (12.5%) in the case group and 22 of 88 (25.0%) in controls were positive for anti-T. gondii IgG antibodies, this difference was statistically significant (OR = 0.42; CI: 0.19-0.95, p = 0.03). The general seroprevalence of CMV (94.3% in the case group vs. 87.5% in the control group, OR = 2.37; CI: 0.78-7.13, p = 0.12) and HSV (63.6% in the case group vs. 62.5% in the control group, OR = 1.05; CI: 0.57-1.94, p = 0.87) were not significantly different between the case and control groups. CONCLUSIONS: Although latent toxoplasmosis has been associated with traffic accidents in recent reports, we found a negative association between latent toxoplasmosis and motorcycle accidents among survivors of these accidents. As such, latent CMV and HSV infections did not differ significantly between the cases compared to the control groups.

RESUMO

Severe pneumonia accounts for 15% of the total severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, and the affected patients require hospitalization and oxygen support. In addition, 5% of patients with severe coronavirus disease 2019 (COVID-19) experience acute respiratory distress syndrome and sepsis, which contributes to the high mortality rate. Moreover, the risk of severe COVID-19 increases with age and is the highest among elderly people over 70 years of age. Notably, these pneumonia cases can be attributed to the reactivation of latent cytomegalovirus (CMV). We hereby report two cases of patients with COVID-19 who required prolonged mechanical ventilation and were later diagnosed with secondary CMV pneumonia. These cases support the theory that in some patients with severe COVID-19, there is a possibility of CMV reactivation, contributing to the disease's severity and pathogenesis. These cases also highlight the risk involved in using steroids for a long time and the requirement of routine evaluation for CMV infection in patients with COVID-19 who require prolonged mechanical ventilation or have difficulty weaning off from the ventilator support.

RESUMO

BACKGROUND: Hemorrhagic varicella (HV) is a particular form of chicken pox.,with high mortality in adults. This form of the disease is rare, to date, approximately 4 cases have been reported. Occasional cases of HV have been documented in adults with hematologic disorders or other diseases. While there is one reported case of simultaneous reactivation of cytomegalovirus in an adult with chickenpox, there is a lack of information regarding changes in liver function indicators for such patients. This is unfortunate, as CMV reactivation can further exacerbate liver failure and increase mortality. In this report, we present a case of hemorrhagic varicella reactivation with cytomegalovirus and provide some relevant discussions. CASE PRESENTATION: We present the case of a 25-year-old male with HV, who had a history of nephrotic syndrome generally controlled with orally administered prednisone at a dosage of 50 mg per day for two months. The patient arrived at the emergency room with complaints of abdominal pain and the presence of hemorrhagic vesicles on his body for the past 3 days. Despite medical evaluation, a clear diagnosis was not immediately determined. Upon admission, the leukocyte count was recorded as 20.96 × 109/L on the first day, leading to the initiation of broad-spectrum antibiotic treatment. Despite the general interpretation that a positive IgG and a negative IgM indicate a previous infection, the patient's extraordinarily elevated IgG levels, coupled with a markedly increased CMV DNA quantification, prompted us to suspect a reactivation of the CMV virus. In light of these findings, we opted for the intravenous administration of ganciclovir as part of the treatment strategy. Unfortunately,,the patient succumbed to rapidly worsening symptoms and passed away. Within one week of the patient's demise, chickenpox gradually developed in the medical staff who had been in contact with him. In such instances, we speculate that the patient's diagnosis should be classified as a rare case of hemorrhagic varicella. CONCLUSION: Swift identification and timely administration of suitable treatment for adult HV are imperative to enhance prognosis.

RESUMO

OBJECTIVES: Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) infections in patients with Neuromyelitis optica spectrum disorder (NMOSD) remain unclear. The objective of this study was to investigate CMV and EBV infections in patients with NMOSD. METHODS: Serum immunoglobin (Ig) G antibodies against CMV and EBV were measured in patients with NMOSD and healthy controls (HCs), including anti-CMV, anti-EBV nuclear antigen-1 (EBNA-1), anti-EBV virus capsid antigen (VCA), and anti-EBV early antigen (EA) IgGs. The immune status ratio (ISR) was used to evaluate the serum anti-CMV and anti-EBV IgG levels and ISR ≧1.10 was defined as seropositivity. RESULTS: In total, 238 serum samples were collected from 94 patients with NMOSD and 144 HCs, and no significant difference of sex and age between NMOSD and HCs. Comparing to the HCs, patients with NMOSD exhibited significantly higher serum anti-CMV IgG level. In contrast, the serum anti-EBNA1 IgG level was significantly lower in patients with NMOSD than in HCs. The serum anti-VCA and anti-EA IgG levels did not differ between the two groups, but the anti-EA seropositivity was significantly higher in NMOSD group than that in HC group. We did not find associations between serum anti-CMV or anti-EBV IgG levels and NMOSD disease stage, immunotherapy, or disability score. CONCLUSIONS: Our findings indicated that increased CMV infection and EBV recent infection, as well as reduced EBV latency infection were associated with the risk of NMOSD. Prospective cohort studies are needed to verify our findings and clarify the correlation between CMV and EBV infections and clinical characteristics of NMOSD.

RESUMO

Background/aim: Cytomegalovirus (CMV) is the most common congenital viral infection. Although most children with congenital CMV (approximately 85%-90%) are asymptomatic at birth, findings such as sensorineural hearing loss, microcephaly, and neurodevelopmental retardation can be observed during the follow-up. Among the brain magnetic resonance imaging (MRI) findings of CMV are white matter abnormalities, polymicrogyria, and periventricular calcification. Since a definitive diagnosis of congenital CMV cannot be made after the neonatal period, the identification of the associated phenotype is diagnostically important, but data are limited in patients who have been retrospectively diagnosed with congenital CMV infection. The aim of this study was to evaluate the short- and long-term neurological follow-up results of congenital CMV infections in a tertiary hospital. Materials and methods: The neurological results of fifteen patients under the age of 18 years, who had a definitive diagnosis of congenital CMV infection and were followed up in a tertiary care hospital between 2011 and 2020, were retrospectively evaluated. Results: Ten of the patients in our study group were male. The mean age at presentation for neurological evaluation was 2.02 ± 1.54 months, with a median follow-up time of 36.3 months (range: 9.3-129.4 months). Neurological disorders detected during the long-term follow-up included cerebral palsy (46.7%), cognitive impairment (46.7%), epilepsy (40%), and sensorineural hearing loss (26.7%). The most common abnormality observed on MRI scans was white matter involvement (53.3%). Conclusion: Early diagnosis and intervention are crucial in congenital CMV infection, as it commonly results in neurological involvement among the patients in our series. This preventable condition warrants further research regarding prenatal/neonatal screening.
