Triple Trouble.

We present a case of a 24-year-old female recently diagnosed with acute leukemia who came with complaints of fever for 14 days, progressive lower limb weakness, and multiple episodes of vomiting in the last 1 day. In nerve conduction studies, a diagnosis of Guillain-Barré syndrome (GBS) was established. Fever with thrombocytopenia workup revealed a positive dengue nonstructural protein 1 (NS1) and immunoglobulin M (IgM) report. Immunophenotyping confirmed pre-B acute lymphoblastic leukemia (ALL). As leukemia is an immunocompromised state, the peripheral nervous system vulnerability is increased, or infection could precipitate an immune neuropathy. About 10% of adult ALL presents with central nervous system (CNS) leukemias; a higher incidence is seen in mature B ALL. There is some evidence to suggest immunosuppression secondary to intensive chemotherapy (vincristine-induced dying back neuropathy), which was not started in our case. This rare combination in a short period of time with a worsening situation paralyzed the line of management. Few reports described GBS in patients with dengue in adults. The association of Guillan-Barre syndrome and ALL could be coincidental or has a pathophysiological basis and is under basic investigation.

Dengue-related acute liver failure-A scoping review.

Infection by dengue virus is common in tropical countries. Hepatic involvement in dengue can range from asymptomatic elevation of transaminases to life-threatening acute liver failure (ALF). Dengue-related ALF (DALF) is responsible for significant morbidity and mortality, especially in Southeast Asia. However, there is a scarcity of literature on DALF, necessitating a thorough examination of its clinical determinants and management strategies. All relevant studies related to DALF were reviewed until December 2023. Case reports, case series and studies reporting ALF in dengue infection were included. Demographics, clinical profiles, management and outcomes of DALF cases were analyzed, which revealed a predominance of DALF incidence in pediatric patients (1.1% to 15.8%) and an upward trend over the years, particularly in India. The proportion of ALF cases attributable to dengue was also higher among pediatric ALF patients (6.7% to 34.3%). Age ≤ 40 years, persistent nausea, vomiting and elevated serum bilirubin and alkaline phosphatase (ALP) with aspartate aminotransferase (AST) > 1000 IU/mL within the first five days of illness, more than 10% of atypical lymphocytes in peripheral blood, platelet count of < 50,000/cu·mm, severe hepatitis at presentation and baseline model for end-stage liver disease (MELD) > 15 were the risk factors for the development of DALF. Histopathological features of DALF included multi-lobular hepatic necrosis, steatosis and occasional cholestasis. Mortality in DALF ranged from 0% to 80%; admission pH and lactate strongly predicted mortality, while mortality was found to be significantly higher in patients with cirrhosis. N-Acetyl cysteine (NAC) has been used as a treatment modality with varying results. There is limited evidence regarding the use of extra-corporeal support systems, while candidate selection for liver transplantation (LT) in DALF remains poorly defined.

Dengue en paciente de 32 días de vida. Reporte de un caso poco habitual / Dengue fever in a 32-day-old patient. A rare case report

El dengue es una enfermedad viral transmitida por la picadura del mosquito Aedes aegypti. El comportamiento del dengue en Argentina es epidémico; la mayoría de los casos se observan en los meses de mayor temperatura. Hasta la semana epidemiológica (SE) 20/2023, se registraron en Argentina 106 672 casos; se vieron afectadas 18 de las 24 provincias que conforman el país. Dentro de los principales grupos de riesgo, se incluyen los menores de 2 años. Reconocer los signos, síntomas e identificar los factores de riesgo es fundamental para el manejo de casos con mayor riesgo de gravedad. Presentamos el caso de una paciente de 32 días de vida que se internó por síndrome febril sin foco, con diagnósticos diferenciales de meningitis viral y sepsis, evolucionó con leucocitosis, plaquetopenia, hipoalbuminemia, asociado a exantema y edemas. Se llegó al diagnóstico de dengue por la clínica, epidemiologia e IgM positiva.

Dengue fever is a viral disease transmitted by the Aedes aegypti mosquitoes. In Argentina, dengue fever is an epidemic disease; most cases are reported during the hot months.Until epidemiological week (EW) 20/2023, 106 672 cases were reported across 18 of the 24 provinces of Argentina. Children younger than 2 years are among the main groups at risk. Recognizing signs and symptoms and identifying risk factors is fundamental for the management of cases at a higher risk of severity. Here we describe the case of a 32-day-old female patient who was hospitalized due to febrile syndrome without a source, who had a differential diagnosis of viral meningitis and sepsis and progressed to leukocytosis, thrombocytopenia, hypoalbuminemia in association with rash and edema. The diagnosis of dengue fever was established based on clinical, epidemiological, and positive IgM data.

Dengue-associated longitudinally extensive transverse myelitis.

We diagnosed a patient with dengue fever who developed acute onset of sensorimotor quadriparesis with bladder involvement, and facial nerve involvement. Despite initial negative results in routine investigations and cerebrospinal fluid analysis, spinal MRI confirmed longitudinally extensive transverse myelitis. The aetiological workup was negative, prompting an investigation into the presence of dengue in the cerebrospinal fluid, which returned positive. This case underscores the importance of considering rare neurological complications in dengue, the value of advanced diagnostic techniques and the potential effectiveness of tailored interventions in challenging cases.

Reporte de caso de dengue clásico a predominio de sintomatología dermatológica en el marco de la epidemia en la provincia de Misiones 2023-2024 / Case of classic dengue with predominance of dermatologic symptoms in the 2023-2024 epidemic in the province of Misiones

Se presenta un caso femenino de dengue clásico (DC) en el marco de la epidemia 2023-2024 en la provincia de Misiones, con predominio de síntomas dermatológicos de exantemas máculo papulosos, habonosos y eritrodérmicos sobre los síntomas sindrómicos cardinales. Las lesiones presentan componente humoral y de extravasación, sin diátesis ni componentes purpúricos apreciables, presentando una rápida y efectiva evolución al eritema y la normalización con tratamiento antihistamínico y corticoide parenteral. De la misma manera se evalúan alteraciones analíticas hematológicas y hepáticas de gran magnitud, con escasa repercusión clínica, que se mensuran en función del riesgo relativo al dengue hemorrágico (DH) y el pronóstico de la paciente. (AU)

A female case of classic dengue (DC) is presented in the context of the 2023-2024 epidemic in the province of Misiones, with a predominance of dermatologic symptoms of maculopapular, hives, and erythrodermic rashes overlapping the cardinal syndromic symptoms. The lesions have a humoral and extravasation component, without any significant diathesis or purpuric components, showing rapid and effective progression to erythema and normalization with antihistamine and parenteral corticosteroid treatment. Similarly, hematologic and hepatic analytical alterations of great magnitude are evaluated, with little clinical impact, measured in terms of relative risk for hemorrhagic dengue (HD) and the prognosis of the patient.

Ischemic Stroke During Dengue Infection: A Report of 2 Cases.

BACKGROUND Involvement of the central nervous system during infection with dengue virus (DENV) is recognized. However, ischemic stroke is rarely reported. Herein are described 2 cases of patients with ischemic stroke in which DENV infection was demonstrated. CASE REPORT The first patient was a 51-year-old woman that presented altered consciousness, monoparesis, facial palsy, dysarthria, Babinski sign, and syncope 7 days from the onset of fever. She had a history of carotid artery atherothrombosis and previous stroke. Magnetic resonance imaging (MRI) showed an acute infarction of the right middle cerebral artery. DENV was confirmed by the presence of NS1 and IgM in serum. The patient was treated with intravenous fluids and recovered well, with only right facial paresis still present at discharge. The second patient was a 50-year-old man who presented with headache, altered consciousness, and mutism after a febrile episode 1 week prior. This patient had a previous history of stroke, glioblastoma resection, epilepsy, hypothyroidism, and diabetes. MRI demonstrated a subacute ischemic event. The diagnosis of dengue was confirmed by serum NS1 and IgM and by RT-PCR in serum and cerebrospinal fluid. DENV-1 serotype was observed in serum and cerebrospinal fluid. The patient was treated with intravenous fluids and was discharged in good condition. In both patients, thrombocytopenia and leukopenia was demonstrated, and hemoconcentration was demonstrated in the second patient. CONCLUSIONS In tropical and subtropical countries, DENV infection can represent a potential cause of ischemic stroke in patients with a history of comorbidities, including stroke.

[Síndrome hemofagocítico linfohistiocitario secundario a Dengue en una paciente de 6 años: reporte de caso].

Background: Dengue fever is a mosquito-borne infectious disease endemic in over 100 countries around the world. Among the complications that dengue can cause the Hemophagocytic Lymphohistiocytosis is one of great concern for its severity and complex diagnosis. Case report: Hereby we document a case of this disease expressed on a previously healthy 6-year-old female patient whose dengue infection was so severe that needed intensive care management with vasoactive drugs and diuretics. After a short period of wellness began newly with fever, pancytopenia, hepatitis, and inflammatory response symptoms. Conclusions: A Dengue associated Hemophagocytic Lymphohistiocytosis syndrome was suspected and treated with intravenous corticosteroids on a 3-day scheme at no signs of malignancy with excellent response. The health care professionals must know about this not novel entity in order to reach an efficient diagnosis and treatment mostly, but not only, those in tropical and sub-tropical regions of the word were dengue virus is endemic.

Antecedentes: La fiebre por dengue es una enfermedad infecciosa transmitida por mosquitos, endémica en más de 100 países alrededor del mundo. La Linfohistiocitosis Hemofagocítica, dentro de las complicaciones que puede ocasionar el dengue, es una de las más preocupantes por su complejidad diagnostica y gravedad. Reporte de caso: Femenino de 6 años de edad, previamente sana, cuya infección por dengue fue tan grave que requirió manejo en cuidados intensivos. Después de un breve período de bienestar recrudeció la fiebre, además de pancitopenia, hepatitis y síntomas de respuesta inflamatoria. Conclusiones: Se sospechó síndrome de Linfohistiocitosis Hemofagocítica asociada a Dengue y se trató con corticoides intravenosos en un esquema de 3 días con excelente respuesta. Los profesionales de la salud deben conocer esta entidad no novedosa para poder llegar a un diagnóstico y tratamiento eficaz en su mayoría, pero no solo, en las regiones tropicales y subtropicales del mundo donde el virus del dengue es endémico.

Infección por dengue sin signos de alarma en un niño con cardiopatía chagásica crónica / Dengue infection in a child with chronic heart disease for Chagas

Se presenta el caso de un preescolar en que se diagnosticó una cardiomiopatía chagásica crónica posterior a una infección aguda por virus dengue. El niño, residente de un área endémica para enfermedad de Chagas, debutó con insuficiencia cardíaca que mejoró con el tratamiento de soporte y tras la resolución completa de la arbovirosis, persistieron los cambios de cardiomiopatía crónica. Esta evidencia de alteración estructural miocárdica se atribuyó a la cardiomiopatía chagásica de base previamente subclínica. La coexistencia de enfermedades infecciosas en el trópico representa un reto diagnóstico, situación a la que se agregan problemas socioeconómicos como la pobreza y falta de acceso a servicios sanitarios básicos.

A case is reported of a chronic chagasic cardiomyopathy in a two-years old child who was diagnosed after an acute dengue virus infection. The patient residing in an endemic area for Chagas disease, debuted with heart failure that improved with support treatment and after the complete resolution of the arbovirus, the changes of chronic cardiomyopathy persisted. The myocardial structural alteration was attributed to subclinical chagasic cardiomyopathy. The coexistence of infectious diseases in the tropics represents a diagnostic challenge, a situation to which are added problems such as poverty and lack of access to basic health services.

Unique Immune Blood Markers Between Severe Dengue and Sepsis in Children.

BACKGROUND: Pediatric dengue and sepsis share clinical and pathophysiologic aspects. Multiple inflammatory and regulatory cytokines, decoy receptors and vascular permeability factors have been implicated in the pathogenesis of both diseases. The differential pattern and dynamic of these soluble factors, and the relationship with clinical severity between pediatric dengue and sepsis could offer new diagnosis and therapeutic strategies. METHODS: We evaluated the concentration levels of 11 soluble factors with proinflammatory, regulatory and vascular permeability involvement, in plasma from children with dengue or sepsis, both clinically ranging from mild to severe, in the early, late and convalescence phases of the disease. RESULTS: During early acute infection, children with sepsis exhibited specific higher concentration levels of IL-6, vascular endothelial growth factor (VEGF), and its soluble decoy receptor II (sVEGFR2) and lower concentration levels of IL-10 and the soluble tumor necrosis factor receptor 2 (sTNFR2), in comparison with children with severe dengue. In addition, the circulating amounts of soluble ST2, and VEGF/sVEGFR2 were widely associated with clinical and laboratory indicators of dengue severity, whereas secondary dengue virus infections were characterized by an enhanced cytokine response, relative to primary infections. In severe forms of dengue, or sepsis, the kinetics and the cytokines response during the late and convalescence phases of the disease also differentiate. CONCLUSIONS: Dengue virus infection and septic processes in children are characterized by cytokine responses of a specific magnitude, pattern and kinetics, which are implicated in the pathophysiology and clinical outcome of these diseases.

Sheehan's Syndrome unmasked by dengue fever: A case report and review of literature.

Sheehan's syndrome is a pituitary disease resulting from severe postpartum hemorrhage and can present with varying degrees of pituitary insufficiency. Although its incidence is decreasing in developed countries, it continues to be one of the most common causes of hypopituitarism in underdeveloped and developing countries. Here, we report a case of Sheehan's syndrome which was diagnosed following an episode of severe dengue infection, in a 38-year-old female.

Role of N-acetylcysteine in liver injury due to dengue fever.

Dengue fever (DF) is a common mosquito-borne viral infection which is endemic in Southeast Asia. Liver involvement may vary from asymptomatic elevation of liver enzymes to fulminant hepatitis. Although the valuable effects of N-acetylcysteine (NAC) in paracetamol toxicity and non-paracetamol liver failure have been extensively studied, its use in DF-associated hepatitis remains unclear. We made a literature search in an online format from libraries such as PubMed, Google Scholar, and EMBASE, and selected 33 articles including original research articles, case reports, and systemic analyses. The majority of the articles reviewed had a positive outcome but treatment strategies involved NAC together with supportive care. Hence, data on sole use of NAC from large randomised control trials remain unclear.

Apparent Dengue Fever Turned Out to be Hemophagocytic Lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is an extremely uncommon hematologic condition that is potentially fatal. It is a disease of histiocyte or lymphocyte hyperactivity, which can be inherited (primary) or acquired (secondary). Dengue fever and HLH both can present with fever, lethargy, and a blood profile of pancytopenia, which makes it difficult to diagnose HLH promptly in a region with dengue endemicity. Clinical and supportive biochemistry findings help clinicians to suspect and diagnose HLH. This article presents a case report of a patient who was diagnosed with dengue fever during initial presentation with subsequent swerves toward HLH. Diagnosing HLH associated with dengue can be difficult. However, it is of utmost importance to diagnose it early, as an early diagnosis and management can lead to significantly improved outcomes.
