Why Ranitidine Given To Patient With Dengue Hemorrhagic Fever
Depends: If there is sepsis, the oxygen goes down and there could be acidosis (low ph). Otherwise, the carrying capacity of oxygen goes down due to lysis of cells but the oxygen seen, the saturation, may be the same. If there is fever, a person breaths faster and the ph goes up and co2 goes down. In short, there is nothing specific attributable to dengue fever in abg. ...Read more
Dengue: There are many mechanisms by which this could occur, including severe anemia induced by the intravascular hemolysis, renal failure, vascular collapse, dehydration and other mechanisms. You need to get a medical education to understand this fully, and don't think that this is place in which to obtain that. Good luck. ...Read more
I had dengue hemorrhagic fever 5 years ago & my lymph nodes swelled. Two have stayed swollen, squishy. Dr says it's normal, checked. How?
Quite similar: Both conditions are caused by dengue virus. One is a milder form but the second one is more serious due to development of very low platelet counts which can lead to bleeding(that is why it is called hemorragic) and occasional fatalities due to shock(fluid leaks) or bleeding. ...Read more
Are you kidding?: There is no way we can discuss pathophysiology in the short space allotted. People with homework assignments should go to the library or do their own web searches. We're here to answer clinical questions. ...Read more
Dengue Fever: Hemorrhagic fever is the most serious manifestation of dengue fever. It can lead to circulatory failure and shock. In it there's a plasma leakage syndrome with increased vascular permeability, platelet count less than 100, 000, fever lasing 2-7 days, and spontaneous bleeding with microvascular fragility. There may be small bruises (petechiae) in the skin all the way to profuse bleeding. ...Read more
American Red Cross:
recommends deferring blood donations for 6 months if you have had Dengue Fever. “In most countries, donors who have been infected with dengue virus are deferred for periods of up to 6 months or even longer if they have received blood transfusions.” REF: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2713854/

No: Dengue hemorrhagic fever is caused by one of four different dengue viruses and it is transmitted by mosquitoes. The cause of kawasaki disease remains unknown. The symptoms and course of the diseases is also very different. ...Read more
Good question: I don't think the exact mechanism is known, but the body's immune response to the virus is responsible for most of the symptoms, . Including the "bone-breaking" pain. In the hemorrhagic fever form, the prior exposure has already created antibodies against the virus and their levels are higher, leading to the bleeding complications. ...Read more
If I have had dengue fever before, should I avoid traveling to countries with prevalent dengue as a rule to avoid hemorrhagic fever?
Yes: Dengue is caused by any one of four related viruses transmitted by mosquitoes. Recovery from infection by one provides lifelong immunity against that particular serotype. However, cross-immunity to the other serotypes after recovery is only partial and temporary. Subsequent infections by other serotypes increase the risk of developing severe dengue. ...Read more
How does thrompocytopenia result in Hemorrhage?.. Whats the Main role of plateles that gets hampered due to dengue fever?
Platelets are the first line of defense in plugging any hole in a blood vessel. Microscopic holes happen with natural activity. Lack of platelets allows bleeding. Thrombocytopeina in Dengue occurs to due a combination of issues. You may consult this site for information.

Hi.im a G6PD patient.and last 2 days ive been suspected with dengue fever.now my whole body are felt itchy. Is that confirm dengue?
Itching?: Itching can happen with or without dengue, so itching does not confirm nor deny dengue. Dengue testing is of 2 types: antibody testing or PCR testing. Antibody testing looks for one's immune system's response to the virus (one's body makes antibodies against the virus). PCR testing looks for actual pieces of virus material, such as the RNA genetic material in the virus. ...Read more
Does repeat dengue fever (hemorrhagic) cause vascular damage leading to initiating aortic dissection ?
2-7 days: Dengue fever is increasing and is a common cause for fever in travelers returning from the tropics or subtropics. Symptoms develop 3-14 days after mosquito bite. Other symptoms include headache, pain behind eyes, muscle aches, joint pain, rash, and nausea. About 1% progress on to the more worrisome dengue hemorrhagic fever (dhf). If you suspect df see your doctor and avoid use of ibuprofen. ...Read more
Dengue Presentation: Dengue presents clinically in less than 20% of cases. The challenge is if you do not show an active disease process and at some point in the future you are bit again, there is a high risk for developing dengue hemorrhagic fever which can be fatal. Lab test are available to determine your exposure to dengue ...Read more
Dengue Fever: Most cases in the continental states are related to world travel and immigration. According to the centers for disease control and prevention, U.S. Citizens are impacted in endemic areas including puerto rico, guam, samoa and us. Virgin islands. ...Read more
Yes, lots of pain: Dengue fever's nickname is 'break bone fever' because every part of your body hurts so much it feels as if your bones are broken. People with dengue have flu-like symptoms including fever, headaches, and muscle aches. Rarely it progresses to severe dengue. It is a viral infection spread by mosquitos which bite during the day and prefer to live in towns & cities. Wear 30% deet to prevent it. ...Read more
Please speak with: Your physician about use of antihistamines to help reduce itching. Take care. ...Read more
Nothing proven: Evidence-based medicine has no specific therapy for dengue beyond rehydration, pain management, and transfusions as required. Water and blood may be the most natural of all treatments. A complementary practitioner familiar with dealing generally with muscle pain and distress might be very helpful. ...Read more
Possibly: Did you have a rash involving your hands with the Dengue? Did you repeatedly wash your hands or use hand sanitizers? Those can be drying to the skin. ...Read more
I am not sure about the cause of hepatomegaly in dengue fever, I would like you describe more, please! thank too much?
Hepatomegaly: Hepatic dysfunction is a well recognized feature of dengue infections, often demonstrated by hepatomegaly and mild-to-moderate increases in transaminase levels although jaundice and acute liver failure are generally uncommon. Debate continues as to whether dengue associated hepatic dysfunction indicates a direct viral effect, arises secondary to an aggressive host immune response to the virus, or reflects a complex interaction of these two mechanisms. ...Read more
Platelet transfusion: There is no known medication to counteract the Dengue virus, so the treatments are aimed at the symptoms and signs. Medications are not available to raise platelet count. Should the count fall low enough that bleeding is a risk, platelet transfusion is the only option to address the problem. ...Read more
I'm dengue fever positive. What can I do to increase my blood platelet level? Is there any food which i need to avoid?
Not likely: May not be dengue related , if there is no bleeind or bruising an platlet count is above 100 , then may just need to wait it out , should go to a blood specialist to make sure there is nothing else wnong. ...Read more
