Dengue fever is a mosquito borne arboviral disease endemic in tropical countries. The spectrum of presentation of dengue fever ranges from classical flu like illness to dengue hemorrhagic fever and dengue shock syndrome. It is usually regarded as a non-neurotropic virus and neurological manifestations of dengue are rare and hypokalemic quadriparesis is even rarer. Here we present a case report of a patient who presented with hypokalemic quadriparesis due to dengue.

Expanded Dengue Syndrome

Dengue is a mosquito-borne disease (female mosquitoes of the Aedes genus, principally Aedes aegypti) caused by any one of four closely related dengue viruses. It is endemic in tropical and subtropical continent. World health organization (WHO) currently estimates there may be 50 -100 million dengue infections worldwide every year with over 2.5 billion people at risk of dengue. Symptomatic dengue virus infection may manifests as undifferentiated fever, classical dengue fever (with or without unusual hemorrhages), and dengue hemorrhagic fever (with or without shock). Isolated organopathy or expanded dengue syndrome (EDS) was coined by WHO in the year 2012 to describe cases, which do not fall into either dengue shock syndrome or dengue hemorrhagic fever. The atypical manifestations noted in expanded dengue are multisystemic and multifaceted with organ involvement, such as liver, brain, heart, kidney, central/peripheral nervous system, gastrointestinal tract, lympho reticular system. Dengue virus has long been considered as a non-neurotropic virus, as animal studies have shown that virus does not cross blood brain barrier. Hyponatremia may be found in association with dengue fever and is thought to be caused by peripheral fluid extravasation and resulting intravascular hypovolaemia. But hyponatremia due to syndrome of inappropriate secretion of anti-diuretic hormone (SIADH) in Dengue fever is rare. We report a 40 years old male who was diagnosed as Dengue fever (Dengue Ns1Ag positive) with thrombocytopenia and hyponatremia. He was admitted and further investigations revealed SIADH. He responded well to cautious sodium replacement and addition of tolvaptan. He recovered completely and was discharged after one week. Thus, all clinicians should keep in mind the possibility of SIADH as a part of expanded dengue syndrome.

Background: Dengue fever has become one of the most important public health concerns now a day due to increasing complications and fatal outcomes. Dengue hemorrhagic fever and dengue shock syndrome are life threatening but reversible complications of dengue fever. Objectives: This study was performed to evaluate the relationship between platelet count and hematocrit with the severity of dengue infection in pediatric age group. Materials & Methods: This was a prospective observational study which included 280 dengue seropositive children of 1 month to 15 years, conducted during 1st June to 30th November, 2018 in a tertiary care hospital of Dhaka. Results: Out of 280 dengue cases, 187(66.78%) had thrombocytopenia and 88(47%) had raised hematocrit. Among the thrombocytopenic patients 44% had dengue fever, 47% had dengue hemorrhagic fever and 9% dengue shock syndrome. A significant co-relation was observed between the severities of thrombocytopenia and raised hematocrit with the appearance of dengue warning signs in case of dengue hemorrhagic fever. Conclusion: Thrombocytopenia and raised hematocrit were related to the severity of dengue hemorrhagic fever. Bangladesh J Child Health 2020; VOL 44 (2) :74-77

Background: Dengue infections can result in a wide spectrum of disease severity ranging from an influenza-like illness (dengue fever; DF) to the life-threatening dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS). The study was aimed to compare the clinical profile of all patients diagnosed with dengue viral infection at NCMC.Methods: This retrospective study included 24 patients infected with dengue virus, aged 19 years to 45 years. Laboratory and haematological data were included.Results Peak of infection occurred in November 2019 and no cases were recorded in October 2019. Common clinical symptoms were fever, joint pains, headache and rash. Common haematological abnormalities were thrombocytopenia. All patients survived. There was no case of dengue hemorrhagic fever or dengue shock syndrome.Conclusions: Significant differences in the clinical profile is possibly because of infection with different serotypes of dengue virus (DENV), concurrent/sequential infection of more than one serotype, and differences in host immune responses associated with host genetic variations.

SUMMARYVitamin D could modulate pathways leading to dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). We examined the associations of serum total 25-hydroxy vitamin D [25(OH)D] and vitamin D binding protein (VDBP) concentrations in patients with uncomplicated dengue fever (DF) with risk of progression to DHF/DSS. In a case–control study nested in a cohort of DF patients who were followed during the acute episode in Bucaramanga, Colombia, we compared 25(OH)D and VDBP at onset of fever between 110 cases who progressed to DHF/DSS and 235 DF controls who did not progress. 25(OH)D concentrations were also compared between the acute sample and a sample collected >1 year post-convalescence in a subgroup. Compared with 25(OH)D ⩾75 nmol/l, adjusted odds ratios (95% CI) for progression were 0·44 (0·22–0·88) and 0·13 (0·02–1·05) for 50 to 75 nmol/l (vitamin D insufficiency) and <50 nmol/l (vitamin D deficiency), respectively (P, trend = 0·003). Mean 25(OH)D concentrations were much lower post-convalescence compared with the acute episode, regardless of case status. Compared with controls, mean VDBP was non-significantly lower in cases. We conclude that low serum 25(OH)D concentrations in DF patients predict decreased odds of progression to DHF/DSS.

Background: Dengue is an arthropod borne viral hemorrhagic fever. It is a major public health concern throughout the tropical and subtropical regions of the world. Objectives: To study clinical profile and laboratory findings of dengue infection in children. Materials and Methods: Children up to the age of 15 years who were confirmed serologically dengue positive (either positive NS1 antigen or positive IgM antibody by ELISA method were included in study. Total 100 patients were studied. Pre tested, semi structured questionnaire were developed and used for data collection. Result and Discussion: In current study, maximum patients were found in Dengue Hemorrhagic Fever (DHF) group (68%), followed by Dengue Fever (25%). Fever was most common clinical manifestation. Maximum patients in this study were in 10 to 15 years of age group, male being more commonly affected. Thrombocytopenia and leukopenia were present in 90% and 69% of patients respectively. Conclusion: School going children were more exposed to mosquito bites during day time school activities, thus maximum patients were from 10 to 15 years of age group. In early diagnosis of dengue fever, ELISA NS1 antigen is seen more promisable. When used in combination with ELISA IgM antibody, it significantly improves the diagnostic algorithm. Thrombocytopenia is more consistent feature of Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Key words: Dengue Hemorrhagic Fever (DHF), Dengue Shock Syndrome (DSS), ELISA NS1 antigen, ELISA IgM antibody.

Background: Dengue epidemic is a major health problem in India. Kerala has reported the highest number of dengue related deaths in the country in 2017 as per the reports of the directorate of National Vector Borne Disease Control Programme (NVBDCP). The aim of the present study is to find out the cardiac manifestations of patients admitted with dengue fever during the epidemic in 2017 in a rural tertiary care centre in coastal Kerala. Method: 341 patients who were admitted in the medicine department of a rural tertiary care Centre in Kerala with Dengue were included in the study. W.H.O case definitions were used for the diagnosis. Complete blood counts, RBS, serum creatinine and liver function tests and E.C.G were carried out in all patients. Echocardiogram and cardiac biomarkers were done when indicated. Results: Males predominated. 317 were diagnosed as dengue fever, 12 as dengue hemorrhagic fever and 12 had dengue shock syndrome. Only four patients succumbed to death. Head ache and myalgia were the common symptoms at the time of presentation. 72 patients had abnormal ECG, but all had normal ECG at the time of discharge, indicating a transient change during the episode. Conclusion: This retrospective observational study included 341 patients admitted in a rural tertiary care Centre in Kerala. Patients were diagnosed as per W.H.O. case definition for dengue. 317 were diagnosed as dengue fever, 12 as dengue hemorrhagic fever and 12 had dengue shock syndrome. Study population was predominantly males. 72 patients had abnormal ECG, but all had normal ECG at the time of discharge, indicating a transient change during the episode.
