A condition due to a dietary deficiency of ascorbic acid (vitamin C), characterized by malaise, lethargy, and weakness. As the disease progresses, joints, muscles, and subcutaneous tissues may become the sites of hemorrhage. Ascorbic acid deficiency frequently develops into SCURVY in young children fed unsupplemented cow's milk exclusively during their first year. It develops also commonly in chronic alcoholism. (Cecil Textbook of Medicine, 19th ed, p1177)
An acquired blood vessel disorder caused by severe deficiency of vitamin C (ASCORBIC ACID) in the diet leading to defective collagen formation in small blood vessels. Scurvy is characterized by bleeding in any tissue, weakness, ANEMIA, spongy gums, and a brawny induration of the muscles of the calves and legs.
A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.
Rats bearing mutant genes which are phenotypically expressed in the animals.
Long chain organic acid molecules that must be obtained from the diet. Examples are LINOLEIC ACIDS and LINOLENIC ACIDS.
Plasma glycoproteins that form a stable complex with hemoglobin to aid the recycling of heme iron. They are encoded in man by a gene on the short arm of chromosome 16.
A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur. (Merck Manual, 16th ed)
A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.
The most abundant protein component of HIGH DENSITY LIPOPROTEINS or HDL. This protein serves as an acceptor for CHOLESTEROL released from cells thus promoting efflux of cholesterol to HDL then to the LIVER for excretion from the body (reverse cholesterol transport). It also acts as a cofactor for LECITHIN CHOLESTEROL ACYLTRANSFERASE that forms CHOLESTEROL ESTERS on the HDL particles. Mutations of this gene APOA1 cause HDL deficiency, such as in FAMILIAL ALPHA LIPOPROTEIN DEFICIENCY DISEASE and in some patients with TANGIER DISEASE.
A condition produced by dietary or metabolic deficiency. The term includes all diseases caused by an insufficient supply of essential nutrients, i.e., protein (or amino acids), vitamins, and minerals. It also includes an inadequacy of calories. (From Dorland, 27th ed; Stedman, 25th ed)
The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.
Anemia characterized by larger than normal erythrocytes, increased mean corpuscular volume (MCV) and increased mean corpuscular hemoglobin (MCH).
Detection of RNA that has been electrophoretically separated and immobilized by blotting on nitrocellulose or other type of paper or nylon membrane followed by hybridization with labeled NUCLEIC ACID PROBES.
The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait).

Dietary antioxidants and magnesium in type 1 brittle asthma: a case control study. (1/213)

BACKGROUND: Type 1 brittle asthma is a rare form of asthma. Atopy, psychosocial factors and diet may contribute to this condition. As increased dietary magnesium has a beneficial effect on lung function and selenium, vitamins A, C and E have antioxidant properties, a study was undertaken to test the hypothesis that patients with brittle asthma have diets deficient in these nutrients compared with subjects with non-brittle asthma and healthy adults. METHODS: A case control study of the dietary intakes of 20 subjects with brittle asthma, 20 with non-brittle asthma, and 20 healthy adults was performed using five day weighed dietary records. Intake of magnesium was the primary outcome measure with selenium and vitamins A, C and E as secondary outcomes. Serum levels were measured at the same time as the dietary assessment. RESULTS: Sixty subjects (27 men) of mean age 49.5 years were recruited and completed the study. Subjects with brittle asthma had statistically lower median dietary intakes of vitamins A and E than the other groups (vitamin A: brittle asthma 522.5 micrograms/day, non-brittle asthma 869.5 micrograms/day, healthy adults 806.5 micrograms/day; vitamin E: brittle asthma 4.3 mg/day, non-brittle asthma 4.6 mg/day, healthy adults 4.5 mg/day). Median dietary intakes for the other nutrients were not significantly different between groups. Serum levels were within normal ranges for each nutrient in all subjects. Intakes less than the reference nutrient intake (RNI) for magnesium and vitamins A and C, and less than the safe intake (SI) for vitamin E were more likely in patients with brittle asthma than in those with non-brittle asthma. CONCLUSION: Nutrient deficiency and reduced antioxidant activity may contribute to disease activity in type 1 brittle asthma, although a prospective study of replacement therapy will be needed to confirm this hypothesis.  (+info)

Parenteral vitamin requirements during intravenous feeding. (2/213)

Serum vitamin levels of 40 patients undergoing parenteral nutrition over a 5-to 42-day period were studied while the subjects received daily water-soluble and once weekly fat soluble vitamin formulations intravenously. Initial serum deficiencies of vitamins A, C, and folate were noted in a large portion of the severely malnourished population. At the replacement levels used in this study a small number of patients developed subnormal levels of vitamins A and D. Improvement in levels for vitamin C and folate were noted for most patients. Vitamin B12 deficiencies were not noted in any patient. Currently available commercial vitamin preparations can be used with safety in the parenterally nourished population and recommended guidelines for weekly infusion of both water and fat soluble vitamins are presented.  (+info)

Aortic wall damage in mice unable to synthesize ascorbic acid. (3/213)

By inactivating the gene for L-gulono-gamma-lactone oxidase, a key enzyme in ascorbic acid synthesis, we have generated mice that, like humans, depend on dietary vitamin C. Regular chow, containing about 110 mg/kg of vitamin C, is unable to support the growth of the mutant mice, which require L-ascorbic acid supplemented in their drinking water (330 mg/liter). Upon withdrawal of supplementation, plasma and tissue ascorbic acid levels decreased to 10-15% of normal within 2 weeks, and after 5 weeks the mutants became anemic, began to lose weight, and die. Plasma total antioxidative capacities were approximately 37% normal in homozygotes after feeding the unsupplemented diet for 3-5 weeks. As plasma ascorbic acid decreased, small, but significant, increases in total cholesterol and decreases in high density lipoprotein cholesterol were observed. The most striking effects of the marginal dietary vitamin C were alterations in the wall of aorta, evidenced by the disruption of elastic laminae, smooth muscle cell proliferation, and focal endothelial desquamation of the luminal surface. Thus, marginal vitamin C deficiency affects the vascular integrity of mice unable to synthesize ascorbic acid, with potentially profound effects on the pathogenesis of vascular diseases. Breeding the vitamin C-dependent mice with mice carrying defined genetic mutations will provide numerous opportunities for systematic studies of the role of antioxidants in health and disease.  (+info)

Ascorbate is depleted by smoking and repleted by moderate supplementation: a study in male smokers and nonsmokers with matched dietary antioxidant intakes. (4/213)

BACKGROUND: Lack of reliable dietary data has hampered the ability to effectively distinguish between effects of smoking and diet on plasma antioxidant status. As confirmed by analyses of comprehensive food-frequency questionnaires, the total dietary intakes of fruit and vegetables and of dietary antioxidants were not significantly different between the study groups in the present study, thereby enabling isolation of the effect of smoking. OBJECTIVE: Our objective was to investigate the effect of smoking on plasma antioxidant status by measuring ascorbic acid, alpha-tocopherol, gamma-tocopherol, beta-carotene, and lycopene, and subsequently, to test the effect of a 3-mo dietary supplementation with a moderate-dose vitamin cocktail. DESIGN: In a double-blind, placebo-controlled design, the effect of a vitamin cocktail containing 272 mg vitamin C, 31 mg all-rac-alpha-tocopheryl acetate, and 400 microg folic acid on plasma antioxidants was determined in a population of smokers (n = 37) and nonsmokers (n = 38). The population was selected for a low intake of fruit and vegetables and recruited from the San Francisco Bay area. RESULTS: Only ascorbic acid was significantly depleted by smoking per se (P < 0.01). After the 3-mo supplementation period, ascorbic acid was efficiently repleted in smokers (P < 0.001). Plasma alpha-tocopherol and the ratio of alpha- to gamma-tocopherol increased significantly in both supplemented groups (P < 0.05). CONCLUSIONS: Our data suggest that previous reports of lower concentrations of plasma vitamin E and carotenoids in smokers than in nonsmokers may primarily have been caused by differences in dietary habits between study groups. Plasma ascorbic acid was depleted by smoking and repleted by moderate supplementation.  (+info)

Plasma vitamin C and food choice in the third Glasgow MONICA population survey. (5/213)

STUDY OBJECTIVE: To determine the contribution of different foods to the estimated intakes of vitamin C among those differing in plasma vitamin C levels, and thereby inform dietary strategies for correcting possible deficiency. DESIGN: Cross sectional random population survey. SETTING: North Glasgow, Scotland, 1992. PARTICIPANTS: 632 men and 635 women, aged 25 to 74 years, not taking vitamin supplements, who participated in the third MONICA study (population survey monitoring trends and determinants of cardiovascular disease). MEASUREMENTS AND MAIN RESULTS: Dietary and sociodemographic information was collected using a food frequency and lifestyle questionnaire. Plasma vitamin C was measured in non-fasted venous blood samples and subjects categorised by cut points of 11.4 and 22.7 micromol/l as being of low, marginal or optimal vitamin C status. Food sources of dietary vitamin C were identified for subjects in these categories. Plasma vitamin C concentrations were compared among groups classified according to intake of key foods. More men (26%) than women (14%) were in the low category for vitamin C status; as were a higher percentage of smokers and of those in the older age groups. Intake of vitamin C from potatoes and chips (fried potatoes) was uniform across categories; while the determinants of optimal versus low status were the intakes of citrus fruit, non-citrus fruit and fruit juice. Optimal status was achieved by a combined frequency of fruit, vegetables and/or fruit juice of three times a day or more except in older male smokers where a frequency greater than this was required even to reach a marginal plasma vitamin C level. CONCLUSION: Fruit, vegetables and/or fruit juice three or more times a day increases plasma vitamin C concentrations above the threshold for risk of deficiency.  (+info)

Vitamin C status and mortality in US adults. (6/213)

BACKGROUND: Low vitamin C status may increase the risk of mortality from cancer and cardiovascular disease. OBJECTIVE: The objective was to test whether an association existed between serum ascorbate concentrations and mortality and whether the association was modified by cigarette smoking status or sex. DESIGN: Serum ascorbate concentrations were measured in adults as part of the second National Health and Nutrition Examination Survey (1976-1980). Vital status was ascertained 12-16 y later. RESULTS: The relative risk (RR) of death, adjusted for potential confounders, was estimated by using Cox proportional hazards models. Men in the lowest (<28.4 micromol/L) compared with the highest (>/=73.8 micromol/L) serum ascorbate quartile had a 57% higher risk of dying from any cause (RR: 1.57; 95% CI: 1.21, 2.03) and a 62% higher risk of dying from cancer (RR: 1.62; 95% CI: 1.01, 2.59). In contrast, there was no increased risk among men in the middle 2 quartiles for these outcomes and no increased risk of cardiovascular disease mortality in any quartile. There was no association between serum ascorbate quartile and mortality among women. These findings were consistent when analyses were limited to nonsmokers or further to adults who never smoked, suggesting that the observed relations were not due to cigarette smoking. CONCLUSIONS: These data suggest that men with low serum ascorbate concentrations may have an increased risk of mortality, probably because of an increased risk of dying from cancer. In contrast, serum ascorbate concentrations were not related to mortality among women.  (+info)

Oral contraceptives and ascorbic acid. (7/213)

Plasma, leukocyte, and platelet ascorbic acid levels are decreased in women ingesting oral contraceptive steroids. Studies have shown that it is the estrogenic component of the oral contraceptive agents that is associated with the decresased ascorbic acid concentrations. Urinary excretion of ascorbic acid does not appear to be increased by the steroids. Although serum levels of copper are increased by estrogens and oral contraceptives, ascorbic acid catabolism does not appear to be increased (unpublished). Our preliminary data on tissue uptake of ascorbic acid suggest that changes in tissue distribution are one possible answer for the observed effects of the steroids on blood levels of ascorbic acid.  (+info)

Fractured neck of femur in black patients: a prospective study. (8/213)

We explored the role of iron overload, deficiency of vitamin C and alcohol abuse in the aetiology of cervical and intertrochanteric fractures of the neck of the femur as a result of minor trauma. We studied prospectively 72 patients (45 men, 27 women). Levels of serum iron markers, vitamin C and alcohol markers were measured. Consumption of alcohol was estimated using questionnaires. The findings were compared with those of an age- and gender-matched control group. The mean age of the men was 59.5 years and of the women 66.9 years, with a male predominance. In the men, iron overload, as shown by high levels of serum ferritin (p < 0.001) and deficiency of vitamin C (p < 0.03), as well as abuse of both Western and the traditional type of alcohol, appear to be important aetiological factors. In women, alcohol abuse was also common, but iron markers and levels of vitamin C did not differ significantly from the control group.  (+info)

Ascorbic acid deficiency can occur due to several reasons, including:

1. Poor diet: A diet that is lacking in vitamin C-rich foods such as citrus fruits, leafy greens, and bell peppers can lead to a deficiency.
2. Inability to absorb vitamin C: Certain medical conditions such as celiac disease, Crohn's disease, and ulcerative colitis can impair the body's ability to absorb vitamin C from food.
3. Increased demand: Vitamin C is essential for wound healing, and during pregnancy and lactation, the body requires more vitamin C to support fetal growth and development.
4. Long-term use of antacids or proton pump inhibitors: These medications can reduce the absorption of vitamin C.

The symptoms of ascorbic acid deficiency can vary depending on the severity of the deficiency and may include:

1. Fatigue and weakness
2. Mood changes such as irritability, anxiety, or depression
3. Difficulty healing from wounds or infections
4. Swelling or bleeding in the gums
5. Joint pain and stiffness
6. Frequent infections such as the common cold or flu
7. Poor digestion and diarrhea

If left untreated, ascorbic acid deficiency can lead to more severe conditions such as scurvy, which can cause:

1. Bleeding gums and teeth
2. Joint pain and swelling
3. Weakened immune system
4. Poor wound healing
5. Fatigue and weakness

Treatment for ascorbic acid deficiency typically involves supplementing with vitamin C, either orally or intravenously, and addressing any underlying causes of the deficiency. In severe cases, hospitalization may be necessary to monitor and treat any complications.

Prevention is key, so it's important to maintain a balanced diet that includes foods rich in vitamin C, such as citrus fruits, leafy greens, and berries. Additionally, avoiding smoking and limiting alcohol consumption can also help prevent ascorbic acid deficiency.

In conclusion, ascorbic acid deficiency is a common nutrient deficiency that can have significant impacts on overall health and well-being. Recognizing the causes, symptoms, and treatment options is essential for proper management and prevention of this condition.

There are several ways to prevent and treat scurvy, including:

* Eating foods rich in vitamin C, such as citrus fruits, leafy greens, and bell peppers.
* Taking vitamin C supplements.
* Increasing the intake of other nutrients that help the body absorb vitamin C, such as calcium and potassium.
* Avoiding foods and drinks that are high in oxalic acid, which can interfere with the absorption of vitamin C.

The discovery of scurvy and its treatment have had a significant impact on the history of medicine and nutrition. It led to the discovery of other essential nutrients and the development of modern nutrition science.

1. Anemia: Folic acid plays a critical role in the production of red blood cells, so a deficiency can lead to anemia, which can cause fatigue, weakness, and shortness of breath.
2. Birth defects: Folic acid is crucial for fetal development during pregnancy, and a deficiency can increase the risk of birth defects such as spina bifida and cleft palate.
3. Heart disease: Folic acid helps to regulate homocysteine levels in the blood, which are associated with an increased risk of heart disease and stroke.
4. Neurological problems: Folic acid is important for the health of the nervous system, and a deficiency can lead to neurological problems such as cognitive impairment, mood disturbances, and seizures.
5. Poor wound healing: Folic acid is necessary for the production of collagen, which is important for wound healing. A deficiency can lead to slow or poor wound healing.
6. Increased risk of cancer: Some studies suggest that a folic acid deficiency may increase the risk of certain types of cancer, such as colon cancer.
7. Hair loss: Folic acid is important for hair growth, and a deficiency can lead to hair loss.
8. Skin problems: Folic acid is important for skin health, and a deficiency can lead to skin problems such as dry, flaky skin and mouth sores.
9. Mood changes: Folic acid plays a role in the production of neurotransmitters, which are chemicals that regulate mood. A deficiency can lead to mood changes such as depression and anxiety.
10. Fatigue: Folic acid is important for energy metabolism, and a deficiency can lead to fatigue and weakness.

Folic acid deficiency can be caused by a number of factors, including:

1. Poor diet: A diet that is low in folate-rich foods can lead to a deficiency.
2. Malabsorption: Certain medical conditions such as celiac disease and Crohn's disease can lead to malabsorption of folic acid.
3. Pregnancy and lactation: Women who are pregnant or breastfeeding have a higher need for folic acid, and may be at risk for deficiency if they do not consume enough.
4. Alcoholism: Heavy alcohol consumption can interfere with the absorption of folic acid.
5. Certain medications: Some medications, such as antacids and proton pump inhibitors, can interfere with the absorption of folic acid.

To diagnose a folic acid deficiency, a healthcare provider may perform a physical exam, take a medical history, and order blood tests to measure folic acid levels. Treatment for a folic acid deficiency typically involves dietary changes and supplements. Dietary changes may include consuming more folate-rich foods, such as leafy green vegetables, legumes, and whole grains. Supplements may include folic acid tablets or liquid supplements. In severe cases of deficiency, injections of folic acid may be necessary. It is important to seek medical attention if you suspect a folic acid deficiency, as untreated deficiencies can lead to serious health problems.

1. Scurvy: A disease caused by a lack of vitamin C in the diet, leading to bleeding gums, weakened immune system, and poor wound healing.
2. Rickets: A disease that affects children and is caused by a lack of calcium and vitamin D, leading to soft and weak bones.
3. Anemia: A condition where the body does not have enough red blood cells or hemoglobin, which can be caused by a lack of iron, folate, or vitamin B12.
4. Beriberi: A condition that affects the heart and nervous system and is caused by a lack of vitamin B1 (thiamine), leading to muscle weakness, fatigue, and heart failure.
5. Goiter: An enlarged thyroid gland that can be caused by a lack of iodine in the diet, leading to hypothyroidism and other complications.
6. Pellagra: A disease caused by a lack of niacin (vitamin B3) in the diet, leading to diarrhea, dermatitis, and dementia.
7. Kwashiorkor: A condition that occurs in children who are malnourished due to a lack of protein in their diet, leading to edema, skin lesions, and diarrhea.
8. Marasmus: A severe form of malnutrition that can be caused by a lack of calories, protein, or other essential nutrients, leading to weight loss, wasting, and weakened immune system.

Deficiency diseases can be prevented by consuming a well-balanced diet that includes a variety of whole foods, such as fruits, vegetables, whole grains, lean proteins, and healthy fats. In some cases, deficiency diseases may also be treated with supplements or other medical interventions.

It is important to note that deficiency diseases can have far-reaching consequences for individuals, families, and communities. Malnutrition can lead to reduced productivity, increased healthcare costs, and a lower quality of life. Therefore, it is essential to prioritize nutrition and take steps to prevent deficiency diseases.

Body weight is an important health indicator, as it can affect an individual's risk for certain medical conditions, such as obesity, diabetes, and cardiovascular disease. Maintaining a healthy body weight is essential for overall health and well-being, and there are many ways to do so, including a balanced diet, regular exercise, and other lifestyle changes.

There are several ways to measure body weight, including:

1. Scale: This is the most common method of measuring body weight, and it involves standing on a scale that displays the individual's weight in kg or lb.
2. Body fat calipers: These are used to measure body fat percentage by pinching the skin at specific points on the body.
3. Skinfold measurements: This method involves measuring the thickness of the skin folds at specific points on the body to estimate body fat percentage.
4. Bioelectrical impedance analysis (BIA): This is a non-invasive method that uses electrical impulses to measure body fat percentage.
5. Dual-energy X-ray absorptiometry (DXA): This is a more accurate method of measuring body composition, including bone density and body fat percentage.

It's important to note that body weight can fluctuate throughout the day due to factors such as water retention, so it's best to measure body weight at the same time each day for the most accurate results. Additionally, it's important to use a reliable scale or measuring tool to ensure accurate measurements.

Symptoms of macrocytic anemia may include fatigue, weakness, pale skin, and shortness of breath. Diagnosis is typically made through a complete blood count (CBC) test that shows an elevated mean corpuscular volume (MCV) and reticulocyte count. Treatment depends on the underlying cause, but may include vitamin supplements, changes in medication, or addressing any underlying medical conditions.

In summary, macrocytic anemia is a type of anemia characterized by large red blood cells that are prone to breakdown and can be caused by various factors. It can cause symptoms such as fatigue, weakness, and shortness of breath, and diagnosis is made through a CBC test. Treatment depends on the underlying cause.

There are several possible causes of methemoglobinemia, including:

1. Exposure to certain medications or chemicals, such as nitrates or aniline dyes.
2. Genetic disorders that affect the production or function of hemoglobin.
3. Infections, such as bacterial infections of the blood or respiratory tract.
4. Poor nutrition or malnutrition.
5. Certain chronic medical conditions, such as sickle cell anemia or thalassemia.

Methemoglobinemia can be diagnosed through a variety of tests, including:

1. Complete blood count (CBC) to measure the levels of methemoglobin in the blood.
2. Blood gas analysis to measure the partial pressure of oxygen and carbon dioxide in the blood.
3. Co-oximetry to measure the levels of methemoglobin and other forms of hemoglobin.
4. Urine tests to check for the presence of abnormal hemoglobin.
5. Genetic testing to identify inherited disorders that may be causing the condition.

Treatment of methemoglobinemia depends on the underlying cause and may include:

1. Administration of oxygen therapy to increase the amount of oxygen in the blood.
2. Use of medications to reduce the levels of methemoglobin and increase the levels of normal hemoglobin.
3. Transfusions of red blood cells to replace abnormal hemoglobin with normal hemoglobin.
4. Management of underlying medical conditions, such as infections or genetic disorders.
5. Dietary changes to address any nutritional deficiencies that may be contributing to the condition.

In severe cases of methemoglobinemia, hospitalization may be necessary to provide oxygen therapy and other treatments. In some cases, patients with methemoglobinemia may require long-term management and follow-up care to prevent complications and manage the underlying cause of the condition.

The condition is inherited in an X-linked recessive pattern, meaning that the gene for G6PD deficiency is located on the X chromosome and affects males more frequently than females. Females may also be affected but typically have milder symptoms or may be carriers of the condition without experiencing any symptoms themselves.

G6PD deficiency can be caused by mutations in the G6PD gene, which can lead to a reduction in the amount of functional enzyme produced. The severity of the condition depends on the specific nature of the mutation and the degree to which it reduces the activity of the enzyme.

Symptoms of G6PD deficiency may include jaundice (yellowing of the skin and eyes), fatigue, weakness, and shortness of breath. In severe cases, the condition can lead to hemolytic anemia, which is characterized by the premature destruction of red blood cells. This can be triggered by certain drugs, infections, or foods that contain high levels of oxalic acid or other oxidizing agents.

Diagnosis of G6PD deficiency typically involves a combination of clinical evaluation, laboratory tests, and genetic analysis. Treatment is focused on managing symptoms and preventing complications through dietary modifications, medications, and avoidance of triggers such as certain drugs or infections.

Overall, G6PD deficiency is a relatively common genetic disorder that can have significant health implications if left untreated. Understanding the causes, symptoms, and treatment options for this condition is important for ensuring appropriate care and management for individuals affected by it.

The symptoms of SARS typically begin within 2-10 days after exposure and can include:

* Fever (>38°C)
* Chills
* Headache
* Body aches
* Fatigue
* Dry cough
* Shortness of breath or difficulty breathing
* Pneumonia

In severe cases, SARS can progress to respiratory failure, which can lead to death. The virus is highly contagious and can be spread through close contact with an infected person, as well as through contact with contaminated surfaces and objects.

SARS was first identified in 2003 in China, and it quickly spread to other countries around the world, causing a global outbreak. The World Health Organization (WHO) declared SARS a Public Health Emergency of International Concern (PHEIC) in March 2003, and it was eventually contained through a combination of measures such as isolation of infected individuals, contact tracing, and the use of personal protective equipment (PPE).

There is no specific treatment for SARS, but supportive care such as oxygen therapy and mechanical ventilation may be provided to help manage symptoms. Antiviral medications have been developed to treat SARS, but their effectiveness is still being studied. Prevention of SARS primarily relies on good hygiene practices, such as frequent handwashing, avoidance of close contact with people who are sick, and wearing PPE when caring for infected individuals.

Overall, Severe Acute Respiratory Syndrome (SARS) is a serious and potentially life-threatening respiratory illness that can be spread through close contact with an infected person. While it has been largely contained through public health measures, it remains important to continue practicing good hygiene and be aware of the risks of SARS in order to prevent its spread.

There are two main types of hemolysis:

1. Intravascular hemolysis: This type occurs within the blood vessels and is caused by factors such as mechanical injury, oxidative stress, and certain infections.
2. Extravascular hemolysis: This type occurs outside the blood vessels and is caused by factors such as bone marrow disorders, splenic rupture, and certain medications.

Hemolytic anemia is a condition that occurs when there is excessive hemolysis of RBCs, leading to a decrease in the number of healthy red blood cells in the body. This can cause symptoms such as fatigue, weakness, pale skin, and shortness of breath.

Some common causes of hemolysis include:

1. Genetic disorders such as sickle cell anemia and thalassemia.
2. Autoimmune disorders such as autoimmune hemolytic anemia (AIHA).
3. Infections such as malaria, babesiosis, and toxoplasmosis.
4. Medications such as antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), and blood thinners.
5. Bone marrow disorders such as aplastic anemia and myelofibrosis.
6. Splenic rupture or surgical removal of the spleen.
7. Mechanical injury to the blood vessels.

Diagnosis of hemolysis is based on a combination of physical examination, medical history, and laboratory tests such as complete blood count (CBC), blood smear examination, and direct Coombs test. Treatment depends on the underlying cause and may include supportive care, blood transfusions, and medications to suppress the immune system or prevent infection.
