Before antibiotic medicines became widely used, rheumatic fever was the single biggest cause of valve disease. Rheumatic fever is a complication of untreated strep throat caused by a group A streptococcal infection. Rheumatic fever can damage body tissues by causing them to swell, but its greatest danger lies in the damage it can do to your heart.
Rheumatic Fever and Rheumatic Heart Disease a Historical Perspective
Rheumatic fever is an inflammatory reaction that can develop as a complication of a Group A streptococcal infection, such as strep throat or scarlet fever.
It occurs when the infection has been untreated or undertreated. Not everyone who has a streptococcal infection will develop rheumatic fever RF , but if RF does develop, symptoms normally appear 2 to 4 weeks after infection. It most commonly affects boys and girls aged 5 to 15 years, but it can occur in adults and younger children. Neurologic complications seem to be more common in females.
RF can have long-term complications, the most common being rheumatic heart disease RHD which develops in 30 to 45 percent of those with RF. Worldwide, RHD is responsible for , — , deaths per year. Before the widespread introduction of antibiotics , RF was a leading cause of acquired heart disease in developed nations, but it is now relatively rare in these countries.
Thanks to routine treatment of Strep throat, RF now only occurs in about 0. RF is caused by a reaction to the bacteria that cause strep throat , so that diagnosis and treatment of this condition can prevent it from developing into RF.
Signs and symptoms generally develop 2 to 4 weeks after a streptococcal infection. Some individuals will experience just one or two of the following symptoms, but others may experience most of them:. Arthritis , or pain and swelling in the joints, affects 75 percent of patients. It normally starts in the larger joints, such as the knees, ankles, wrists, and elbows, before moving to other joints. This inflammation normally resolves within weeks, without causing permanent damage.
Inflammation of the heart can lead to chest pain, palpitations, a sensation that the heart is fluttering or pounding hard, panting, and shortness of breath, and fatigue. On average, around 50 percent of patients develop carditis or valvulitis, a potentially fatal inflammation of the heart that can have serious, long-term effects. Younger children are more susceptible. Symptoms usually pass within a few months but can last up to 2 years.
They are not normally permanent. Other symptoms include a red, blotchy, skin rash, which appears in 1 in 10 cases. Less common are nosebleeds, abdominal pain, bumps and lumps, or nodules, under the skin, and a high fever over degrees Fahrenheit.
Treatment aims to destroy the bacteria, relieve symptoms, control inflammation, and prevent recurrences of RF. Antibiotics, such as penicillin , may be given to destroy any remaining strep bacteria in the body. Further antibiotics may be prescribed, to prevent recurrence. This may continue for years depending on the age of the person and whether or not the heart is affected.
Long-term, and even lifelong, preventive antibiotics may be necessary to prevent recurring inflammation of the heart. It is important to remove all traces of streptococcal bacteria, as any remaining bacteria can lead to repeated occurrences of RF and a significantly higher risk of heart damage, which can become permanent.
Anti-inflammatory drugs : Naproxen, for example, may help to reduce pain, inflammation, and fever. Corticosteroids : Prednisone may be given if the patient does not respond to first-line anti-inflammatory medications, or if there is inflammation of the heart. Anticonvulsant medications : These can treat severe chorea symptoms. Examples include valproic acid Depakene or Stavzor , carbamazepine Carbatrol or Equetro , haloperidol Haldol and risperidone Risperdal.
Anyone who has RF as a child will need to inform their doctor as they get older because heart damage can appear many years later. They will pay particular attention to any recent illness along with the following:. Symptoms of RF, and specifically inflammation, may persist for weeks, months, or longer, causing long-term problems. Globally, RHD is estimated to affect more than 15 million people per year and cause more than , deaths. The inflammation causes permanent damage to the heart, most commonly the mitral valve, the valve between the upper and lower chambers of the left side of the heart.
Other conditions that may develop if there is damage to heart tissue, the mitral valve, or other heart valves include:. RF is now rare in developed countries, but it remains a risk elsewhere.
Researchers continue to seek effective ways to prevent RF and its complications. The main cause of RF is Group A streptococcus GAS , a bacteria that can cause infections such as Strep throat with or without scarlet fever and skin infections like impetigo , and cellulitis.
Genetic factors may increase the risk. The chance of having RF appears to be higher if another family member has had it. Strep bacteria have a protein that resembles one found in some body tissues. In RF, the tissues that they attack are those of the heart, joints, central nervous system CNS and skin.
These tissues react by becoming inflamed. If a patient with Strep bacteria takes a complete course of antibiotic treatment, the chances of RF developing are very low. In 8 out of 10 cases, the signs and symptoms of RF resolve within 12 weeks. Between 30 and 45 percent of people with RF will develop heart problems. Recurrences of rheumatic fever often occur within 5 years.
In the past, RF was a major cause of mortality, but now this is rare in industrialized countries. However, RF is fatal in 1. Environmental factors, such as overcrowding, poor sanitation, and poor access to healthcare increase the risk of developing RF. Leaving strep throat or scarlet fever untreated or partially treated by not finishing a complete course of antibiotics increases the risk of RF significantly. Having low blood pressure with a high pulse can be a normal response to certain situations, such as after exercising or standing up too quickly.

NICE has issued rapid update guidelines in relation to many of these. This guidance is changing frequently. Rheumatic fever RF used to be a fairly common disease amongst children in developed countries until about the middle of the 20th century. It was a major cause of death in children until and a common cause of chronic structural heart disease in developed countries. In developing countries it still remains a major cause of death and heart disease.
In March , a year-old woman in the USA was hospitalized for a month with a life-threatening streptococcal infection at a New Haven, Connecticut, hospital. She had streptococcal septicemia from childbirth. Treatments with sulfa drugs, blood transfusions, and surgery had no effect. As a last resort, her doctors injected her with a tiny amount of an obscure experimental drug called penicillin. Her hospital chart, now at the Smithsonian Institution, indicates a sharp overnight drop in temperature; by the next day, she was no longer delirious.

Росио натянула ночную рубашку, глубоко вздохнула и открыла дверь в комнату. Когда она вошла, глаза немца чуть не вывалились из орбит. На ней была черная ночная рубашка; загорелая, орехового оттенка кожа светилась в мягком свете ночника, соски призывно выделялись под тонкой прозрачной тканью. - Komm doch hierher, - сказал немец сдавленным голосом, сбрасывая с себя пижаму и поворачиваясь на спину. Росио через силу улыбнулась и подошла к постели. Но, посмотрев на распростертую на простынях громадную тушу, почувствовала облегчение.
Вот как? - снисходительно произнес Стратмор холодным как лед голосом. - Значит, тебе известно про Цифровую крепость. А я-то думал, что ты будешь это отрицать. - Подите к черту. - Очень остроумно.
- Джабба засопел и сделал изрядный глоток. - Если бы в игрушке Стратмора завелся вирус, он бы сразу мне позвонил. Стратмор человек умный, но о вирусах понятия не имеет. У него в голове ничего, кроме ТРАНСТЕКСТА. При первых же признаках беды он тут же поднял бы тревогу - а в этих стенах сие означает, что он позвонил бы. - Джабба сунул в рот кусочек сыра моцарелла.
