Amphotericin B- and fluconazole-resistant Candida spp., Aspergillus fumigatus, and other newly emerging pathogenic fungi are susceptible to basic antifungal peptides. (1/1523)The present study shows that a number of basic antifungal peptides, including human salivary histatin 5, a designed histatin analog designated dhvar4, and a peptide from frog skin, PGLa, are active against amphotericin B-resistant Candida albicans, Candida krusei, and Aspergillus fumigatus strains and against a fluconazole-resistant Candida glabrata isolate.

Synergic effects of tactolimus and azole antifungal agents against azole-resistant Candida albican strains. (2/1523)We investigated the effects of combining tacrolimus and azole antifungal agents in azole-resistant strains of Candida albicans by comparing the accumulation of [3H]itraconazole. The CDR1-expressing resistant strain C26 accumulated less itraconazole than the CaMDR-expressing resistant strain C40 or the azole-sensitive strain B2630. A CDR1-expressing Saccharomyces cerevisiae mutant, DSY415, showed a marked reduction in the accumulation of both fluconazole and itraconazole. A CaMDR-expressing S. cerevisiae mutant, DSY416, also showed lower accumulation of fluconazole, but not of itraconazole. The addition of sodium azide, an electron-transport chain inhibitor, increased the intracellular accumulation of itraconazole only in the C26 strain, and not in the C40 or B2630 strains. Addition of tacrolimus, an inhibitor of multidrug resistance proteins, resulted in the highest increase in itraconazole accumulation in the C26 strain. The combination of itraconazole and tacrolimus was synergic in azole-resistant C. albicans strains. In the C26 strain, the MIC of itraconazole decreased from >8 to 0.5 mg/L when combined with tacrolimus. Our results showed that two multidrug resistance phenotypes (encoded by the CDR1 and CaMDR genes) in C. albicans have different substrate specificity for azole antifungal agents and that a combination of tacrolimus and azole antifungal agents is effective against azole-resistant strains of C. albicans.

A comparison of itraconazole versus fluconazole as maintenance therapy for AIDS-associated cryptococcal meningitis. National Institute of Allergy and Infectious Diseases Mycoses Study Group. (3/1523)This study was designed to compare the effectiveness of fluconazole vs. itraconazole as maintenance therapy for AIDS-associated cryptococcal meningitis. HIV-infected patients who had been successfully treated (achieved negative culture of CSF) for a first episode of cryptococcal meningitis were randomized to receive fluconazole or itraconazole, both at 200 mg/d, for 12 months. The study was stopped prematurely on the recommendation of an independent Data Safety and Monitoring Board. At the time, 13 (23%) of 57 itraconazole recipients had experienced culture-positive relapse, compared with 2 relapses (4%) noted among 51 fluconazole recipients (P = .006). The factor best associated with relapse was the patient having not received flucytosine during the initial 2 weeks of primary treatment for cryptococcal disease (relative risk = 5.88; 95% confidence interval, 1.27-27.14; P = .04). Fluconazole remains the treatment of choice for maintenance therapy for AIDS-associated cryptococcal disease. Flucytosine may contribute to the prevention of relapse if used during the first 2 weeks of primary therapy. (+info)
Randomized placebo-controlled trial of fluconazole prophylaxis for neutropenic cancer patients: benefit based on purpose and intensity of cytotoxic therapy. The Canadian Fluconazole Prophylaxis Study Group. (4/1523)A randomized, double-blind trial comparing oral fluconazole (400 mg daily) with placebo as prophylaxis for adult patients receiving intensive cytotoxic therapy for acute leukemia or autologous bone marrow transplantation was conducted in 14 Canadian university-affiliated hospitals. Although fluconazole prophylaxis did not obviate the need for parenteral antifungal therapy compared with placebo (81 [57%] of 141 vs. 67 [50%] of 133, respectively), its use resulted in fewer superficial fungal infections (10 [7%] of 141 vs. 23 [18%] of 131, respectively; P = .02) and fewer definite and probable invasive fungal infections (9 vs. 32, respectively; P = .0001). Fluconazole recipients had fewer deaths attributable to definite invasive fungal infection (1 of 15 vs. 6 of 15, respectively; P = .04) and achieved more frequent success without fungal colonization (52 [37%] of 141 vs. 27 [20%] of 133, respectively; P = .004; relative risk reduction, 85%) than did placebo recipients. Patients benefiting the most from fluconazole prophylaxis included those with acute myeloid leukemia who were undergoing induction therapy with cytarabine plus anthracycline-based regimens and those receiving marrow autografts not supported with hematopoietic growth factors. Fluconazole prophylaxis reduces the incidence of superficial fungal infection and invasive fungal infection and fungal infection-related mortality among patients who are receiving intensive cytotoxic chemotherapy for remission induction.

The effect of fluconazole on cyclophosphamide metabolism in children. (5/1523)Fluconazole is increasingly used in children receiving chemotherapy. Many of these patients are being treated with cyclophosphamide, which must undergo hepatic metabolism to produce active alkylating species. As a consequence of the cytochrome P-450 inhibitory properties of fluconazole, a potential interaction exists between these two agents that could influence the therapeutic effect of cyclophosphamide. To investigate this interaction, a retrospective case series of patients was chosen from a population of children with a previously established profile of cyclophosphamide metabolism. Twenty-two children who were not receiving other therapy known to influence drug metabolism were selected and analyzed in terms of fluconazole treatment; of these, nine were receiving fluconazole and thirteen were identified as controls. Study design was not randomized. The plasma clearance of cyclophosphamide was lower in patients receiving fluconazole [mean(SD) 2.4(0.71) versus 4.2(1.2) l/h/m2, p =.001]. In vitro studies were performed to characterize the interaction between fluconazole and cyclophosphamide in six human liver microsomes. The concentration of fluconazole required to reduce the production of 4-hydroxycyclophosphamide to 50% of control values (IC50) varied between 9 and 80 microM (median 38 microM). Further studies of the effect of fluconazole on 4-hydroxycyclophosphamide production in vivo are warranted to determine whether this interaction reduces the therapeutic effect of cyclophosphamide in clinical practice.

Effects of azole antifungal drugs on the transition from yeast cells to hyphae in susceptible and resistant isolates of the pathogenic yeast Candida albicans. (6/1523)Oral infections caused by the yeast Candida albicans are some of the most frequent and earliest opportunistic infections in human immunodeficiency virus-infected patients. The widespread use of azole antifungal drugs has led to the development of drug resistance, creating a major problem in the treatment of yeast infections in AIDS patients and other immunocompromised individuals. Several molecular mechanisms that contribute to drug resistance have been identified. In C. albicans, the ability to morphologically switch from yeast cells (blastospores) to filamentous forms (hyphae) is an important virulence factor which contributes to the dissemination of Candida in host tissues and which promotes infection and invasion. A positive correlation between the level of antifungal drug resistance and the ability to form hyphae in the presence of azole drugs has been identified. Under hypha-inducing conditions in the presence of an azole drug, resistant clinical isolates form hyphae, while susceptible yeast isolates do not. This correlation is observed in a random sample from a population of susceptible and resistant isolates and is independent of the mechanisms of resistance. 35S-methionine incorporation suggests that growth inhibition is not sufficient to explain the inhibition of hyphal formation, but it may contribute to this inhibition.

Assessment of therapeutic response of oropharyngeal and esophageal candidiasis in AIDS with use of a new clinical scoring system: studies with D0870. (7/1523)We developed and compared five scoring systems designed to quantitate therapeutic response in cases of oropharyngeal candidiasis. We utilized prospectively collected data on 114 patients treated with several doses of the azole D0870. Patients were infected with fluconazole-susceptible (n = 49) or -resistant organisms (MIC, > or = 16 mg/mL; n = 61). Patients with fluconazole resistance had lower CD4+ cell counts at baseline; more symptoms (P = .0006); a higher frequency of dysgeusia (P = .004), dysphagia (P = .006), and throat pain (P = .0034); and greater oral coverage by plaques of Candida. There was no difference between the two groups in terms of colony-forming units, and any change did not correlate with response to therapy. Resolution of dysphagia (P < .01) and oral pain (P < .01) correlated well with response to therapy, unlike retrosternal pain and throat pain, which were also less frequent. Xerostomia, a "furry" taste, and dysgeusia were frequent nonspecific symptoms. Scoring system C, weighting resolution of a symptom higher than absence of a symptom at baseline, yielded the best correlation with global outcome (r = 0.86) and allows the quantitation of incomplete but clinically beneficial responses to therapy.

In vitro antifungal activity of nikkomycin Z in combination with fluconazole or itraconazole. (8/1523)Nikkomycins are nucleoside-peptide antibiotics produced by Streptomyces species with antifungal activities through the inhibition of chitin synthesis. We investigated the antifungal activities of nikkomycin Z alone and in combination with fluconazole and itraconazole. Checkerboard synergy studies were carried out by a macrobroth dilution procedure with RPMI 1640 medium at pH 6.0. At least 10 strains of the following fungi were tested: Candida albicans, other Candida spp., Cryptococcus neoformans, Coccidioides immitis, Aspergillus spp., and dematiacious fungi (including Exophiala jeanselmei, Exophiala spinifera, Bipolaris spicifera, Wangiella dermatitidis, Ochroconis humicola, Phaeoannellomyces werneckii, and Cladophialophora bantiana), and 2 strains each of Fusarium, Scedosporium, Paecilomyces, Penicillium, and Trichoderma spp. A total of 110 isolates were examined. Inocula of fungal elements were standardized by hemacytometer counting or spectrophotometrically. MICs and minimum lethal concentrations (MLCs) were determined visually by comparison of growth in drug-treated tubes with growth in drug-free control tubes. Additive and synergistic interactions between nikkomycin and either fluconazole or itraconazole were observed against C. albicans, Candida parapsilosis, Cryptococcus neoformans, and Coccidioides immitis. Marked synergism was also observed between nikkomycin and itraconazole against Aspergillus fumigatus and Aspergillus flavus. No antagonistic interaction between the drugs was observed with any of the strains tested. (+info)

It's important to note that these are just some of the possible causes of a sore throat and difficulty breathing, and it's always best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
A type of meningitis caused by a fungal infection. Fungal meningitis is a serious and potentially life-threatening condition that can occur when fungi enter the bloodstream and spread to the membranes surrounding the brain and spinal cord (meninges).
The most common types of fungi that cause fungal meningitis are Aspergillus, Candida, and Cryptococcus. These fungi can be found in soil, decaying organic matter, and contaminated food. People with weakened immune systems, such as those with HIV/AIDS or taking immunosuppressive drugs, are at a higher risk of developing fungal meningitis.
Symptoms of fungal meningitis may include fever, headache, stiff neck, sensitivity to light, and confusion. If left untreated, fungal meningitis can lead to serious complications such as brain damage, hearing loss, and seizures. Treatment typically involves the use of antifungal medications, and in severe cases, surgery may be necessary to remove infected tissue or relieve pressure on the brain.
Preventive measures for fungal meningitis include avoiding exposure to fungal sources, practicing good hygiene, and taking antifungal medications as prescribed by a healthcare professional. Early diagnosis and treatment are critical in preventing serious complications and improving outcomes for patients with fungal meningitis.
Candidemia can cause a range of symptoms, including fever, chills, rapid heart rate, and confusion. In severe cases, it can lead to organ failure and death. Treatment typically involves the use of antifungal medications, and in some cases, hospitalization is necessary to manage the infection and monitor the patient's condition.
Preventative measures to reduce the risk of developing candidemia include proper handwashing and hygiene, avoiding close contact with people who are sick, and ensuring that medical equipment and surfaces are properly cleaned and disinfected.

AROIs are a major cause of morbidity and mortality in individuals with HIV/AIDS, and they can be prevented or treated with antimicrobial therapy, supportive care, and other interventions.
The most common cause of candidiasis is an imbalance in the natural bacteria and yeast that live in and around the vagina. This imbalance can be caused by a variety of factors, including:
* Taking antibiotics, which can kill off the "good" bacteria that keep candida in check
* Pregnancy and menopause, when hormonal changes can lead to an overgrowth of yeast
* Diabetes, which can cause excess sugar in the body that feeds the growth of yeast
* Weakened immune system
* Poor hygiene or poor fitting clothing and underwear that can trap moisture and create a warm environment for yeast to grow.
The symptoms of candidiasis can vary from person to person, but common signs include:
* Itching, burning, and redness of the vulva and vagina
* A thick, white discharge that looks like cottage cheese and has no odor or a mild, sweet smell
* Pain or discomfort during sex
* Difficulty getting pregnant (infertility) if the infection is severe or recurrent.
A healthcare provider can diagnose candidiasis by performing a physical examination and taking a sample of vaginal discharge for testing. The provider may also take a culture of the yeast to determine which type of candida is causing the infection.
Candidiasis can be treated with antifungal medications, such as clotrimazole or terconazole. These medications are available over-the-counter or by prescription and come in creams, tablets, or suppositories. To help clear the infection, treatment may also include:
* Avoiding irritants such as douches, powders, or scented soaps
* Wearing loose-fitting clothing and cotton underwear
* Keeping the genital area clean and dry
* Avoiding sex during treatment
If left untreated, candidiasis can lead to complications such as:
* Recurrent infections
* Inflammation of the vulva (vulvodynia)
* Inflammation of the vagina (vaginitis)
* Pain during sex
* Difficulty getting pregnant (infertility)
To prevent candidiasis, women can take the following steps:
* Practice good hygiene by washing the genital area gently with soap and water
* Avoid using douches, powders, or scented soaps
* Wear loose-fitting clothing and cotton underwear
* Change out of wet or sweaty clothes as soon as possible
* Avoid sex during treatment for candidiasis.
With proper treatment, the prognosis for candidiasis is good. The infection usually clears up within a week or two with antifungal medication. However, recurrent infections can be more difficult to treat and may require longer courses of therapy. In some cases, candidiasis can lead to complications such as inflammation of the vulva or vagina, which can be more challenging to treat.
It is important for women to seek medical attention if they experience any symptoms of candidiasis, as early diagnosis and treatment can help prevent complications and improve outcomes.
1. Gastroesophageal reflux disease (GERD): A condition in which stomach acid flows back up into the esophagus, causing symptoms such as heartburn and difficulty swallowing.

Diagnosis of blastomycosis is based on a combination of clinical findings, laboratory tests, and imaging studies. Treatment typically involves antifungal medications, which can be effective in resolving symptoms and preventing complications. However, the disease can be challenging to diagnose and treat, and long-term follow-up is often necessary to ensure that the infection has been fully cleared.
Preventive measures for blastomycosis include avoiding contact with contaminated soil and water, wearing protective clothing and equipment when working outdoors in areas where the fungus is prevalent, and taking antifungal medications as prescribed by a healthcare provider. Early diagnosis and treatment are critical to preventing severe complications and improving outcomes for patients with blastomycosis.
There are several types of fungal eye infections, including:
1. Aspergillosis: This is a common type of fungal infection that affects the eye. It is caused by the fungus Aspergillus and can occur in people with weakened immune systems or pre-existing eye conditions.
2. Candidemia: This is another common type of fungal infection that affects the eye. It is caused by the fungus Candida and can occur in people with weakened immune systems or pre-existing eye conditions.
3. Cryptococcosis: This is a rare type of fungal infection that affects the eye. It is caused by the fungus Cryptococcus and can occur in people with weakened immune systems, such as those with HIV/AIDS.
4. Histoplasmosis: This is a rare type of fungal infection that affects the eye. It is caused by the fungus Histoplasma and can occur in people who have been exposed to the fungus in soil or bird droppings.
5. Blastomycosis: This is a rare type of fungal infection that affects the eye. It is caused by the fungus Blastomyces and can occur in people who have been exposed to the fungus in soil or water.
Fungal eye infections can cause a range of symptoms, including redness, discharge, pain, and vision loss. Treatment typically involves antifungal medication and may also include surgery to remove any infected tissue. In severe cases, fungal eye infections can lead to blindness if left untreated.
Prevention measures for fungal eye infections include good hygiene practices, such as washing hands regularly and avoiding close contact with people who have the infection. People with weakened immune systems should also avoid exposure to fungi by avoiding outdoor activities during peak fungal growth seasons and wearing protective clothing when working or playing in areas where fungi are likely to be present.
Overall, fungal eye infections are uncommon but can be serious conditions that require prompt medical attention. If you suspect you may have a fungal eye infection, it is important to seek medical care as soon as possible to receive proper diagnosis and treatment.
Symptoms of neutropenia may include recurring infections, fever, fatigue, weight loss, and swollen lymph nodes. The diagnosis is typically made through a blood test that measures the number of neutrophils in the blood.
Treatment options for neutropenia depend on the underlying cause but may include antibiotics, supportive care to manage symptoms, and in severe cases, bone marrow transplantation or granulocyte-colony stimulating factor (G-CSF) therapy to increase neutrophil production.
