What Is Invasive Candidiasis
Medical illustration of Candida albicans.
Invasive candidiasis is an infection caused by a yeast called Candida. Unlike Candida infections in the mouth and throat or vaginal yeast infections, which are localized to one part of the body, invasive candidiasis is a serious infection that can affect the blood, heart, brain, eyes, bones, or other parts of the body.1
Candida normally lives inside the body and on the skin without causing any problems.2 However, in certain patients who are at risk, Candida can enter the bloodstream or internal organs and cause an infection. A Candida bloodstream infection, also called candidemia, is the most common form of invasive candidiasis.1 In the United States, candidemia is one of the most common causes of bloodstream infections in hospitalized patients,34 and it often results in long hospital stays and death. It is also responsible for high medical costs.5
Antifungal medication can treat invasive candidiasis. Certain patients such as those with cancer or bone marrow or organ transplants might receive antifungal medication to prevent invasive candidiasis.6
Seroprevalence And Determinants Of Transfusion Transmissible Infections Among Voluntary Blood Donors In Homabay Kisumu And Siaya Counties In Western Kenya
2018, BMC Research Notes
Transfusion transmissible infections especially human immunodeficiency virus and hepatitis viruses, are a constant threat to blood safety for the recipient, and more endemic in Africa, thus making donors in this region vulnerable to risk of exposure . Moreover, co-infection is also common due to similar routes of transmission , with prevalence varying with time and regions . Infections with HIV compromises immunological status of a person, hepatitis B and C viral infections cause liver cirrhosis and hepatocellular carcinoma while infections with syphilis results in neonatal mortality thus, high quality screening for the four major TTIs have become mandatory and irreducible minimum that must be tested in all blood donations to achieve safety threshold .
What Is The Treatment For Invasive Candidiasis
Antifungal medication is used to treat invasive candidiasis. Antifungal medications that are called echinocandins, like caspofungin, are given by intravenous injection. Those called azoles, like fluconazole, are given intravenously or orally.
If you have candidemia, your treatment will continue for two weeks after your symptoms go away and the Candida is out of your bloodstream. Invasive candidiasis in the heart, brain, or bones needs a longer time to be treated.

Can I Take The Test At Home
Vaginal yeast infection test kits are available for home testing. However, at-home testing does not include all of the tests that can be performed in a medical office, such as a culture, microscopic examination of discharge, and a physical examination. Types of at-home vaginal yeast infection tests include:
- At-home vaginal pH testing: This test allows you to test your vaginal pH at home using a test strip. When taking this test, its important to remember that an at-home vaginal pH test alone cannot determine if vaginal yeast is the source of your symptoms.
- At-home NAAT testing: These at-home vaginal yeast infection tests enable you to collect a sample of vaginal discharge at home and mail it to a lab for analysis. NAAT testing can detect common causes of vaginitis, including yeast, bacterial vaginosis, and the STD trichomoniasis.
Because at-home testing cannot be tailored to match your medical history and symptoms, at-home vaginal yeast infection tests should not be used in place of a visit to your doctor or gynecologist.
More information about at-home testing for yeast infections is available at at-home yeast infection testing.
What Doctors Look For When They Suspect A Yeast Infection
At your doctors office, your doctor will ask you about your symptoms and your overall medical history, including past vaginal infections and sexually transmitted diseases.
Your doctor will then conduct a gynecological exam to check for redness, swelling, discharge, and odor.
Your doctor will also examine your cervix for swelling and redness, and your vaginal walls for dry, white spots.
To get a concrete diagnosis, your doctor will likely take a sample of your vaginal secretions and examine it under a microscope.

Roc Analysis Of Apache Ii Score And Serum Albumin
APACHE II score and serum albumin were the factors most strongly associated with mortality among patients with fungal bloodstream infections. After subjecting these variables to ROC analysis, the results showed that when the APACHE II score was > 19, the area under the curve was 0.801, and when serum albumin was 25g/L, AUC was 0.636, which indicated that these were the best predictors for mortality among fungal bloodstream infection patients .

Blood Infection: Causes Symptoms And Treatment
Do you know that a blood infection can be due to a bacterial infection in your blood?
Blood infection or Sepsis is a serious infection and can occur when bacteria are in your bloodstream.
When the infection-fighting process turns on your body, it can cause organs to function poorly and abnormally.
Moreover, sepsis can progress to septic shock. It can cause a drop in blood pressure that can lead to severe organ problems and death.
Early treatment with antibiotics and intravenous improves your chance of survival.
However, understanding your risk is the first step in preventing the condition.

How Common Are Yeast Infections In Diabetes
Yeast infections are twice as common among people with diabetes compared to the general population. This is more so among those with uncontrolled blood sugar levels.
Some diabetes medications such as Invokana , Jardiance , Farxiga , and Steglaro are associated with higher risk of yeast infections affecting the groin. This is because these medications lower blood sugar by having kidneys dump sugar in urine, therefore giving yeast a source of energy to grow.
Distribution Of Fungal Strains
Over the 10-year study period, 98 fungal strains from bloodstream infections, mainly Candida spp., were obtained from the blood cultures from 81 ICU patients. Candida albicans was most common , followed by C. tropicalis , C. glabrata , C. parapsilosis , C. krusei , and C. guilliermondii . Over the 10-year study period, the prevalence of C. albicans decreased, while other Candida spp. increased each year . In addition, three strains of Cryptococcus neoformans, two of Talaromyces marneffei, three of Pichia pastoris, and one of Saccharomyces cerevisiae were isolated.

Antimicrobial susceptibility of strains
The drug sensitivity analysis of the five main fungi in the 98 strains showed that > 95% of C. albicans strains were sensitive to all antifungal agents tested. All strains ofC. tropicalis were sensitive to caspofungin and amphotericin B, and> 90% were sensitive to azoles. Candida glabrata were relatively less sensitive to azoles 67% were sensitive to fluconazole and itraconazole, while all strains were sensitive to caspofungin and amphotericin B. Of the C. parapsilosis strains, 83% were sensitive to caspofungin, and all were sensitive to the other antifungals .

Complement In Candida Sepsis
Considerable evidence shows that complement activation plays a central role in systemic infection and sepsis.58,59 The interaction of C. albicans with complement has recently been reviewed in detail and we refer to the review of Luo et al.60 Although patients suffering from genetic defects in complement do not show increased risk for fungal infections, evidence from both murine and in vitro experiments indicates an important role of complement in antifungal responses. However, even in patients with chronic granulomatous disease a severe functional defect of neutrophils – numbers of invasive Candida infections are surprisingly low, . This may reflect both redundancy of immune effector functions or the fact that intestinal barrier integrity may be at large protective against Candida invasion.25,60a
Types Of Bacterial Infections In The Blood
Bacteria are a natural, healthy part of our bodies, especially in certain areas like the skin or gut. These areas are known as microbiomes. Science still hasn’t determined whether healthy humans have a blood microbiome .
However, when certain bacteria get into the bloodstream, they can cause a bacterial infection in the blood. While terms like “septicemia,” “sepsis,” “blood infection,” and “blood poisoning” are sometimes used interchangeably, there are important differences among them, such as:
- “Bacteremia” is a term meaning a bacterial infection of the blood.
- “” is the term for a life-threatening inflammatory response.
- “” is another term for “sepsis,” but is not used in the medical community
- “” is a rapid, life-threatening drop in blood pressure caused by sepsis.
- “Blood poisoning” is a non-medical term used to describe any infection of the blood. This term is often used interchangeably with septicemia.
- “Blood infection” is a general term for any infection of the blood. This is most often septicemia but can also include blood infections caused by viruses.

Causes Of Blood Infection
Blood infection occurs when bacteria causing infection in another part of your body enter your bloodstream.
The presence of bacteria in the blood is referred to as bacteremia or septicemia.
The terms septicemia and sepsis are often interchangeable, though technically they are not quite the same.
Moreover, is the state of having bacteria in your blood and can lead to sepsis.
However, any type of infection can cause sepsis.
It can be either bacterial fungal or viral.
And these infections agents do not necessarily need to be in your bloodstream to bring about sepsis.
Such infection often occurs in the lung, abdomen, and urinary tract.
Blood poisoning often occurs when bacteria enter your bloodstream in the conjunction with another infection, you will not have sepsis without having an infection.
Some common causes of infections that can also lead to sepsis are:

How To Prevent Yeast Infections
Having good can lower the risk of yeast infections among individuals with diabetes. Other factors that may reduce the risk of yeast infections include:
wearing underpants that allow moisture to escape, like those made of cotton
allowing skin foldslike the groin and space between toesto dry properly after bathing
avoiding unnecessary antibiotic use
If you are taking one of the diabetes medications mentioned above that increase sugar in urine, the risk of yeast infection may be reduced by drinking plenty of water and having good personal hygiene.

What Are The Symptoms Of Yeast Infections
Symptoms depend on the infection location:
Skin folds: itching, rash, and skin breakdown
Vagina: itching, burning, and whitish/yellowish vaginal discharge
Mouth: bitter taste, sore mouth or throat. White patches on the tongue and back of the mouth. Painful cracks at the corners of the mouth
Nails: change in nail shape and color
Candida Lives In And On The Body
Candida, the fungus that causes invasive candidiasis, normally lives inside the body and on the skin without causing any problems.1 In some people who are at higher risk for the infection, Candida can enter the bloodstream or internal organs and cause invasive candidiasis. For example, this can happen when a central venous catheter is inserted and left in place for a long time, during surgery, or when the immune system is weakened during chemotherapy. Healthcare workers can also carry Candida on their hands.2,3 A few outbreaks of candidemia have been linked to healthcare workers hands,4,5 so hand hygiene in healthcare settings is important for preventing the spread of infections.

Diabetes And Yeast Infections
Diabetes is a chronic condition affecting the body’s ability to process glucose , leading to dangerously high blood sugar levels. Researchers have found a link between these high blood sugar levels from diabetes and vaginal yeast infections.
People with type 2 diabetes may be even more susceptible to getting vaginal yeast infections, likely because they have more sugar in their system, disrupting the vagina’s balance of bacteria and yeast.

How Do You Get Bacteria In Your Blood
As mentioned, bacteremia is bacteria found in the blood, and it can sometimes lead to sepsis. Bacteremia can result from everyday activities, which may include brushing your teeth vigorouslyâthis can lead to bacteria living on the gums being forced into the bloodstream. Bacteria can also enter the bloodstream during digestion. Typically, bacteremia arising as a result of these normal activities is asymptomatic and doesnât last long because your immune system fights it off.
Medical or dental procedures can also cause bacteremia bacteria on the surface may enter the bloodstream after being dislodged during a visit to the dentist, or when catheters are placed into the body at a hospital. Bacterial infections such as pneumonia can also allow bacteria to enter the bloodstream, as can childhood bacterial infections such as ear infections, strep throat, or impetigo.

Candida species is a leading cause of nosocomial infections and the most common fungal infection in intensive care units. Candida infection ranges from invasive candidal disease to blood stream infections . The incidence of Candida infection has been rising over the past two decades, particularly with the use of immunosuppressive drugs for cancer and HIV1,2,3 , and most of these infections occur in ICU settings.4 Candida infection is associated with high mortality and morbidity. Studies have shown that mortality attributable to candidaemia ranges from 5 to 71% depending on the study. 5.6.7Candidaemia is also associated with longer length of hospital stay and higher cost of care.
Hospital and Definitions:
From this model, the candidaemia risk score calculated would be: Candidaemia risk score = 1.184 for previous or current antibiotic use + 0.639 for presence of central venous line + 1.186 for total parenteral nutrition + 0.760 for positive endotracheal culture for Candida + 1.255 for positive urine culture for Candida.

How Is Invasive Candidiasis Diagnosed
Your doctor may order one of the following Candida tests to diagnose invasive candidiasis.
Blood culture test. The most common test for invasive candidiasis is a blood culture test. Your doctor will take your blood sample and send it to a lab to see if Candida grows from it.
Mannan antigen and anti-mannan antibody. This Candida antibody test is used to diagnose invasive candidiasis. It checks for the presence of mannan, which is a carbohydrate present in the cell wall of Candida species.
C. albicans germ tube antibody . This Candida antibody test detects candidiasis caused by the fungus Candida albicans. It can also detect other Candida species with lower sensitivity.
-Î²-D-glucan . This test looks for the presence of BDG in the sample. Like mannan, BDG is a carbohydrate found in the cell wall of many fungus species. This test is effective in the detection of invasive fungal infections. But it canât be used to distinguish between Candida and other species of fungi.
Polymerase chain reaction . There’s no FDA-approved PCR test for Candida, but some commercial PCR tests are available. They use blood samples to detect Candida. These tests target the five most common infective Candida species: C. albicans, C. glabrata, C. parapsilosis, C. tropicalis, and C. krusei. This allows doctors to identify the exact species causing the condition, but the results can be difficult to interpret.
Once the tests are done, results are available in a few days.

Can Vaginal Yeast Infections Be Prevented
For most girls, there’s no way to prevent yeast infections. Girls may feel more comfortable and have less irritation if they wear breathable cotton underwear and loose clothes and avoid vaginal sprays and douches. Wearing cotton underwear may also help prevent yeast infections. If your daughter has diabetes, keeping her blood sugar levels under control will help her avoid getting yeast infections.
If you think your daughter has an infection, call your doctor for advice. Don’t give her leftover antibiotics or someone else’s antibiotics or medicine because they be the wrong choice for her condition. And taking antibiotics when they are not needed can make a girl more likely to get yeast infections.
