CANDIDIASIS
*CANDIDIASIS*, also called thrush or moniliasis, is a yeast infection. (Candida albicans) its an organism that normally makes a quiet home for itself on your skin and doesn't bother anyone. We all carry this organism on our skin, in our mouth, in our gastrointestinal tract (gut), and, in the case of women, in the vagina.
Occasionally the yeast multiplies uncontrollably, causing pain and inflammation. Candidiasis may affect the skin. This includes the external surface skin and the skin of the vagina, the penis, and the mouth. Candidiasis may also infect the blood stream or internal organs such as the liver or spleen. By far the most common problems are skin, mouth and vaginal infections. It also is a common cause of diaper rash. These can be bothersome infections, but are not life threatening.
Candidiasis can kill if it reaches the bloodstream or vital organs such as the heart, but this is rare even in people with damaged immune systems and is almost unheard of in healthy people. Nevertheless, candidiasis is a constant nuisance, and sometimes a serious threat to people with AIDS and some cancer patients who lack the immune resources to fight it.
You don't catch candidiasis. The yeast is already there. A number of factors can increase the chance of the yeast growing out of control. The leading cause is overuse of *Antibiotics*. Yeast must compete for the right to live on us with various other organisms, many of them bacteria. These bacteria, which live on the skin and in the intestine and vagina, among other places, are harmless but good at fighting off yeast. When we take antibiotics to deal with less friendly bacteria, we kill off these harmless ones as well. Yeast, which is unaffected by antibiotics, moves into the vacated spots once occupied by bacteria, and starts to grow and multiply.
Causes
Steroids and some cancer medications weaken the immune system and can allow yeast to flourish. Candida albicans infections of the mouth (known as oral thrush) most often develop in people with diseases such as cancer and AIDS. They can also develop in people with diabetes or in people who have long-term irritation resulting from dentures. Taking birth control pills increases your chances of getting vaginal candidiasis. Hot weather, poor hygiene, and tight clothing are also risk factors, as they create the ideal environment for candida.
Other conditions that tend to encourage yeast include obesity and pregnancy. Yeast generally infects intertriginous areas, that is, areas where skin contacts skin. Overweight people have more folds in their skin. They also sweat more, and Candida albicans is fond of moist skin. Pregnancy causes temporary obesity and may weaken the immune system, increasing the risk of yeast infections.
Experts disagree on the question of sexual transmission. Some research has suggested that it's very unlikely for an infected woman to give a man candidiasis. On the other hand, it's not unlikely that a man could give candidiasis back to his partner once he has it. Recent research has actually found Candida albicans in the sperm of men whose partners suffered from recurrent yeast infections. You should be aware of this possibility if a yeast infection keeps coming back.
Candida yeasts are generally present in healthy humans, frequently part of the human body's normal oral and intestinal flora, and particularly on the skin; however, their growth is normally limited by the human immune system and by competition of other microorganisms, such as bacteria occupying the same locations in the human body. Candida requires moisture for growth, notably on the skin. For example, wearing wet swimwear for long periods of time is believed to be a risk factor. In extreme cases, superficial infections of the skin or mucous membranes may enter into the bloodstream and cause systemic Candida infections.
Factors that increase the risk of candidiasis include HIV/AIDS, mononucleosis, cancer treatments, steroids, stress, antibiotic usage, diabetes, and nutrient deficiency. Hormone replacement therapy and infertility treatments may also be predisposing factors. Treatment with antibiotics can lead to eliminating the yeast's natural competitors for resources in the oral and intestinal flora; thereby increasing the severity of the condition. A weakened or undeveloped immune system or metabolic illnesses are significant predisposing factors of candidiasis. Almost 15% of people with weakened immune systems develop a systemic illness caused by Candida species Diets high in simple carbohydrates have been found to affect rates of oral candidiases.
C. albicans was isolated from the vaginas of 19% of apparently healthy women, i.e., those who experienced few or no symptoms of infection. External use of detergents or douches or internal disturbances (hormonal or physiological) can perturb the normal vaginal flora, consisting of lactic acid bacteria, such as lactobacilli, and result in an overgrowth of Candida cells, causing symptoms of infection, such as local inflammation. Pregnancy and the use of oral contraceptives have been reported as risk factors. Diabetes mellitus and the use of antibiotics are also linked to increased rates of yeast infections.
In penile candidiasis, the causes include sexual intercourse with an infected individual, low immunity, antibiotics, and diabetes. Male genital yeast infections are less common, but a yeast infection on the penis caused from direct contact via sexual intercourse with an infected partner is not uncommon
Symptoms and Complications
A candida infection of the skin appears as a clearly defined patch of red, itchy skin, often leaking fluid. Scabs and pustules may be seen around the edge of the rash. It will usually be found in areas such as the groin, the folds of the buttocks, between the breasts, toes, or fingers, and in the navel. It may be hard to see on people with darker skin.
A vaginal yeast infection may well result in a slow leakage of a thick, white, clumpy (cottage-cheese-like) substance with no or minimal odour. The vagina may itch or burn, especially during urination or sex. Pain or discomfort during intercourse is common.
Candidal paronychia is candidiasis of the fingernails. It often strikes people whose hands are in water a lot. Sometimes it presents as a painful, red, swollen area around the fingernail. In worse cases, the fingernail may separate, revealing a discoloured white or yellow nail bed.
Yeast infections of the penis are rare but may cause the tip to be red, swollen, and painful.
Signs and symptoms
Signs and symptoms of candidiasis vary depending on the area affected. Most candidal infections result in minimal complications such as redness, itching, and discomfort, though complications may be severe or even fatal if left untreated in certain populations. In healthy (immunocompetent) persons, candidiasis is usually a localized infection of the skin, fingernails or toenails (onychomycosis), or mucosal membranes, including the oral cavity and pharynx (thrush), esophagus, and the genitalia (vagina, penis, etc.); less commonly in healthy individuals, the gastrointestinal tract, urinary tract, and respiratory tract are sites of candida infection.
In immunocompromised individuals, Candida infections in the esophagus occur more frequently than in healthy individuals and have a higher potential of becoming systemic, causing a much more serious condition, a fungemia called candidemia.
Symptoms of esophageal candidiasis include difficulty swallowing, painful swallowing, abdominal pain, nausea, and vomiting.
Thrush is commonly seen in infants. It is not considered abnormal in infants unless it lasts longer than a few weeks.
Infection of the vagina or vulva may cause severe itching, burning, soreness, irritation, and a whitish or whitish-gray cottage cheese-like discharge. Symptoms of infection of the male genitalia (balanitis thrush) include red skin around the head of the penis, swelling, irritation, itchiness and soreness of the head of the penis, thick, lumpy discharge under the foreskin, unpleasant odour, difficulty retracting the foreskin (phimosis), and pain when passing urine or during sex.
Common symptoms of gastrointestinal candidiasis in healthy individuals are anal itching, belching, bloating, indigestion, nausea, diarrhea, gas, intestinal cramps, vomiting, and gastric ulcers. Perianal candidiasis can cause anal itching; the lesion can be erythematous, papular, or ulcerative in appearance, and it is not considered to be a sexually transmissible disease. Abnormal proliferation of the candida in the gut may lead to dysbiosis. While it is not yet clear, this alteration may be the source of symptoms generally described as the irritable bowel syndrome, and other gastrointestinal diseases.
