Cutaneous candidiasis caused by Candida kefyr.

Candidiasis is an acute or subacute fungal infection caused by fungi that belongs to candida genus, with Candida albicansbeing the most frequent causative agent. Candida kefyr is a rare cause of candidiasis which has been reported in systemic candidiasis and deep infections. However, to date, it has never been reported as a cause in dermatophytosis. We report a case of candidiasis caused by Candida kefyr in a 72-year-old woman with a chief complaint of pruritic erythematous rash on the back from one day prior to admission. Diagnosis was established based on clinical features, direct microscopic examination with 10% potassium hydroxide solution, gram staining. The fungal species was determined by carbohydrate fermentation test which showed a positive result for Candida kefyr. The patient was treated with miconazole cream and fusidic cream and showed significant clinical improvement.

Interventions for preventing mastitis after childbirth.

BACKGROUND: Despite the health benefits of breastfeeding, initiation and duration rates continue to fall short of international guidelines. Many factors influence a woman's decision to wean; the main reason cited for weaning is associated with lactation complications, such as mastitis. Mastitis is an inflammation of the breast, with or without infection. It can be viewed as a continuum of disease, from non-infective inflammation of the breast to infection that may lead to abscess formation. OBJECTIVES: To assess the effectiveness of preventive strategies (for example, breastfeeding education, pharmacological treatments and alternative therapies) on the occurrence or recurrence of non-infective or infective mastitis in breastfeeding women post-childbirth. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (3 October 2019), and reference lists of retrieved studies. SELECTION CRITERIA: We included randomised controlled trials of interventions for preventing mastitis in postpartum breastfeeding women. Quasi-randomised controlled trials and trials reported only in abstract form were eligible. We attempted to contact the authors to obtain any unpublished results, wherever possible.  Interventions for preventing mastitis may include: probiotics, specialist breastfeeding advice and holistic approaches.   DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and assessed the certainty of the evidence using GRADE. MAIN RESULTS: We included 10 trials (3034 women). Nine trials (2395 women) contributed data. Generally, the trials were at low risk of bias in most domains but some were high risk for blinding, attrition bias, and selective reporting. Selection bias (allocation concealment) was generally unclear. The certainty of evidence was downgraded due to risk of bias and to imprecision (low numbers of women participating in the trials). Conflicts of interest on the part of trial authors, and the involvement of industry funders may also have had an impact on the certainty of the evidence. Most trials reported our primary outcome of incidence of mastitis but there were almost no data relating to adverse effects, breast pain, duration of breastfeeding, nipple damage, breast abscess or recurrence of mastitis. Probiotics versus placebo Probiotics may reduce the risk of mastitis more than placebo (risk ratio (RR) 0.51, 95% confidence interval (CI) 0.35 to 0.75; 2 trials; 399 women; low-certainty evidence). It is uncertain if probiotics reduce the risk of breast pain or nipple damage because the certainty of evidence is very low. Results for the biggest of these trials (639 women) are currently unavailable due to a contractual agreement between the probiotics supplier and the trialists. Adverse effects were reported in one trial, where no woman in either group experienced any adverse effects. Antibiotics versus placebo or usual care The risk of mastitis may be similar between antibiotics and usual care or placebo (RR 0.37, 95% CI 0.10 to 1.34; 3 trials; 429 women; low-certainty evidence). The risk of mastitis may be similar between antibiotics and fusidic acid ointment (RR 0.22, 95% CI 0.03 to 1.81; 1 trial; 36 women; low-certainty evidence) or mupirocin ointment (RR 0.44, 95% CI 0.05 to 3.89; 1 trial; 44 women; low-certainty evidence) but we are uncertain due to the wide CIs. None of the trials reported adverse effects. Topical treatments versus breastfeeding advice The risk of mastitis may be similar between fusidic acid ointment and breastfeeding advice (RR 0.77, 95% CI 0.27 to 2.22; 1 trial; 40 women; low-certainty evidence) and mupirocin ointment and breastfeeding advice (RR 0.39, 95% CI 0.12 to 1.35; 1 trial; 48 women; low-certainty evidence) but we are uncertain due to the wide CIs. One trial (42 women) compared topical treatments to each other. The risk of mastitis may be similar between fusidic acid and mupirocin (RR 0.51, 95% CI 0.13 to 2.00; low-certainty evidence) but we are uncertain due to the wide CIs. Adverse events were not reported. Specialist breastfeeding education versus usual care The risk of mastitis (RR 0.93, 95% CI 0.17 to 4.95; 1 trial; 203 women; low-certainty evidence) and breast pain (RR 0.93, 95% CI 0.36 to 2.37; 1 trial; 203 women; low-certainty evidence) may be similar but we are uncertain due to the wide CIs. Adverse events were not reported. Anti-secretory factor-inducing cereal versus standard cereal The risk of mastitis (RR 0.24, 95% CI 0.03 to 1.72; 1 trial; 29 women; low-certainty evidence) and recurrence of mastitis (RR 0.39, 95% CI 0.03 to 4.57; 1 trial; 7 women; low-certainty evidence) may be similar but we are uncertain due to the wide CIs. Adverse events were not reported. Acupoint massage versus routine care Acupoint massage probably reduces the risk of mastitis compared to routine care (RR 0.38, 95% CI 0.19 to 0.78;1 trial; 400 women; moderate-certainty evidence) and breast pain (RR 0.13, 95% CI 0.07 to 0.23; 1 trial; 400 women; moderate-certainty evidence). Adverse events were not reported. Breast massage and low frequency pulse treatment versus routine care Breast massage and low frequency pulse treatment may reduce risk of mastitis (RR 0.03, 95% CI 0.00 to 0.21; 1 trial; 300 women; low-certainty evidence). Adverse events were not reported. AUTHORS' CONCLUSIONS: There is some evidence that acupoint massage is probably better than routine care, probiotics may be better than placebo, and breast massage and low frequency pulse treatment may be better than routine care for preventing mastitis. However, it is important to note that we are aware of at least one large trial investigating probiotics whose results have not been made public, therefore, the evidence presented here is incomplete. The available evidence regarding other interventions, including breastfeeding education, pharmacological treatments and alternative therapies, suggests these may be little better than routine care for preventing mastitis but our conclusions are uncertain due to the low certainty of the evidence. Future trials should recruit sufficiently large numbers of women in order to detect clinically important differences between interventions and results of future trials should be made publicly available.

Chitosan and phospholipid assisted topical fusidic acid drug delivery in burn wound: Strategies to conquer pharmaceutical and clinical challenges, opportunities and future panorama.

Burn is the immense public health issue globally. Low and middle income countries face extensive deaths owing to burn injuries. Availability of conventional therapies for burns has always been painful for patients as well as expensive for our health system. Pharmaceutical experts are still searching reliable, cheap, safe and effective treatment options for burn injuries. Fusidic acid is an antibiotic of choice for the management of burns. However, fusidic acid is encountering several pharmaceutical and clinical challenges like poor skin permeability and growing drug resistance against burn wound microbes like Methicillin resistant Staphylococcus aureus (MRSA). Therefore, an effort has been made to present a concise review about molecular pathway followed by fusidic acid in the treatment of burn wound infection in addition to associated pros and cons. Furthermore, we have also summarized chitosan and phospholipid based topical dermal delivery systems customized by our team for the delivery of fusidic acid in burn wound infections on case-to-case basis. However, every coin has two sides. We recommend the integration of in-silico docking techniques with natural biomacromolecules while designing stable, patient friendly and cost effective topical drug delivery systems of fusidic acid for the management of burn wound infection as future opportunities.

Hepatotoxicity and hematologic complications induced by fusidic acid in a patient with hepatitis B cirrhosis: A case report.

RATIONALE: Fusidic acid (FA) is an active agent against gram-positive bacteria such as Staphylococcus, it is generally well tolerated and the major adverse effects are mild gastrointestinal discomfort, diarrhea, and headache. However, some rare side effects such as granulocytopenia and thrombocytopenia have also been reported. Here we report a case of FA-induced hepatotoxicity and hematologic toxicity. PATIENT CONCERNS: A 54-year-old woman with hepatitis B cirrhosis was referred to us because of fever, Staphylococcus aureus was identified in the twice blood culture, and intravenous FA was given (0.5 g, q8 hours). Twelve days after FA therapy, she developed nausea and jaundice. Meanwhile, complete blood cell count showed neutropenia (white blood cell count of 1360/µL, neutrophil of 619/µL) and aggravated thrombocytopenia (platelet count of 18,000/µL). Adverse drug reaction was suspected, and FA was stopped immediately, after 1 day of discontinuation of FA, nose bleeding occurred and the platelet count declined further and reached the lowest value of 4000/µL. DIAGNOSES: Hepatotoxicity and hematologic complications induced by FA were diagnosed. INTERVENTIONS AND OUTCOMES: The FA was stopped immediately, and concentrated platelet transfusion was used. Five days after withdrawal of FA, jaundice resolved and the hematologic index returned to the level before the medication. LESSONS: Hematologic adverse effect accompanying with hepatotoxicity may be induced by FA. Though the risk is rather low, it should not be overlooked.

Nano-engineered lipid-polymer hybrid nanoparticles of fusidic acid: an investigative study on dermatokinetics profile and MRSA-infected burn wound model.

Staphylococcus aureus (SA) and methicillin-resistant Staphylococcus aureus (MRSA) have been a major cause of morbidity in thermally injured patients. The skin barrier gets disrupted and loss of immunity further makes burn sites an easy target for bacterial colonization. In the current study, combined potential of lipid-polymer hybrid nanoparticles (LPHNs) with fusidic acid was explored as a promising strategy toward combating resistant bacteria in burn wound infection sites. The developed systems exhibited particle size (310.56 ± 5.22 nm), zeta potential (24.3 ± 4.18 mV) and entrapment efficiency (78.56 ± 3.56%) with a spherical shape. The hybrid nanoparticles were further gelled into carbopol and demonstrated better permeation (76.53 ± 1.55%) and retention characteristics (56.41 ± 4.67%) as compared to the conventional formulation. The topical delivery of FA into the skin layers by FA-LPHN gel was found to be significantly higher (p < 0.05) compared to FA-CC. The in vivo potential was further assessed in murine burn wound model inflicted with MRSA 33591 bacterium with the determination of parameters like bacterial burden, wound contraction, morphological and histopathological examination of wounds. The bacterial count decreased drastically in FA-LPHN gel group (5.22 log CFU/mL) on day 3 with significant difference in comparison to FA-CC. The wound size reduction in FA-LPHN gel (68.70 ± 3.65%) was higher as compared to FA-CC (73.30 ± 4.23%) and control groups (83.30 ± 4.40%) on day 5. The current study presents a safe and effective formulation strategy for the treatment of MRSA-infected burn wounds by providing moist environment and prevention from bacterial infection.

Successful control of hidradenitis suppurativa with verapamil: a case report.

An inappropriate immunologic response has been suggested to play a role in the pathogenesis of hidradenitis suppurativa (HS). Adalimumab was the first TNF-α inhibitor approved for moderate to severe HS. We report on a case of HS (Hurley stage 2) in a 39-year-old man, who had received fusidic acid and isotretinoin treatments without evident benefit during the last 8 years. The patient noticed a reduction in the number of lesions and quality of life (DLQI from 27 to 6) in the 2 months following verapamil initiation for cluster headache. When verapamil was stopped, the lesions recurred within 1.5 months. The patient resumed taking verapamil as before and a remission occurred. Verapamil has been shown to inhibit TNF-α and IL-1ß in vitro and in vivo. We hypothesize that verapamil inhibits the inflammatory process through the TNF-α/IL-1 pathway involved in the HS physiopathology. Compared to biologic agents as anti-TNF-α (adalimumab) and anti-IL1 (anakinra), verapamil is safer and cheaper. Given its possible role on TNF-α/IL-1, verapamil may represent an alternative therapeutic option in mild and moderate HS.

[Right treatment of red eyes - prescription of topical antibiotics for infectious conjunctivitis is still common in Sweden]. / Rekommendationer följs inte vid okomplicerad konjunktivit - Tillståndet behandlas ofta med topikala antibiotika i strid mot aktuell kunskap.

Conjunctivitis is one of the most common ophthalmologic conditions in general medical practice. In most cases, it is self-limiting and do not require topical antibiotic therapy. In a retrospective, observational cohort study during 2013-2017 in a region in Sweden conjunctivitis was diagnosed in 32 000 cases in primary care. Antibiotics were prescribed in 66% of undefined and in 83% of purulent conjunctivitis. Fusidic acid was the most common medication with 81% followed by chloramphenicol with 17%. Although unnecessary, the treatment is probably harmless. Toxicity is uncommon and the cost is low. Increased consciousness of this issue may however decrease resistance to antibiotics and support evidence-based medical practice.

Cationic-bilayered nanoemulsion of fusidic acid: an investigation on eradication of methicillin-resistant Staphylococcus aureus 33591 infection in burn wound.

AIM: The aim of the current study was to investigate the therapeutic efficacy of cationic-charged bilayered nanoemulsion for topical delivery of fusidic acid in eradicating methicillin-resistant Staphylococcus aureus (MRSA) bacterial burn wound infection. MATERIALS & METHODS: The developed carriers were characterized for particle size, antibacterial activity, cell viability assay in HaCat cell lines, rheological profile, ex vivo and in vivo studies, namely, full thickness MRSA 33591 murine burn wound infection via topical route. RESULTS: The developed cationic bilayered nanogel offered enhanced drug permeation, reduction in bacterial load and enhanced wound contraction along with faster re-epithelialization in burn wounds. CONCLUSION: The results encourage the exploration of the potential of cationic nanogel in treating resistant microorganisms such as MRSA, especially for application in burn wound infection.

Targeting PRPK Function Blocks Colon Cancer Metastasis.

The biological functions of the p53-related protein kinase (PRPK) remain unclear. We have previously demonstrated that PRPK is phosphorylated by the T-LAK cell-originated protein kinase (TOPK) and that phosphorylated PRPK (p-PRPK) promotes colon cancer metastasis. Here, we analyzed colon adenocarcinomas from 87 patients and found that higher expression levels of p-PRPK were associated with later stages of metastatic dissemination (stage III and IV) as compared with earlier stages (stages I and II). Indeed, levels of p-PRPK were higher in metastatic versus malignant human colon adenocarcinomas. Knocking down PRPK expression attenuated colorectal liver and lung metastasis of colon cancer cells in vivo An in vitro kinase assay indicated that active PRPK does not phosphorylate p53 directly. We found that PRPK phosphorylates survivin, a regulator of colon cancer metastasis. PRPK phosphorylates survivin at Thr34, which is important for survivin stability. Taken together, our data strongly suggest that the PRPK signaling pathway promotes colon cancer metastasis by modulating survivin stability, and that PRPK could be a new prognostic marker for the survival of colon cancer patients. In addition, we identified an FDA-approved bacteriostatic antibiotic, fusidic acid sodium salt (fusidic acid or FA) as an inhibitor of PRPK, and show that FA combined with 5-fluorouracil (5-FU) inhibited PRPK activity and colon cancer metastasis to the lung in mice. We contend that the combination of FA with 5-FU could be an alternative therapeutic strategy to traditional chemotherapy for colon cancer patients with poor prognosis.

Oral and Topical Antibiotics for Clinically Infected Eczema in Children: A Pragmatic Randomized Controlled Trial in Ambulatory Care.

PURPOSE: Eczema may flare because of bacterial infection, but evidence supporting antibiotic treatment is of low quality. We aimed to determine the effect of oral and topical antibiotics in addition to topical emollient and corticosteroids in children with clinically infected eczema. METHODS: We employed a 3-arm, blinded, randomized controlled trial in UK ambulatory care. Children with clinical, non-severely infected eczema were randomized to receive oral and topical placebos (control), oral antibiotic (flucloxacillin) and topical placebo, or topical antibiotic (fusidic acid) and oral placebo, for 1 week. We compared Patient Oriented Eczema Measure (POEM) scores at 2 weeks using analysis of covariance (ANCOVA). RESULTS: We randomized 113 children (40 to control, 36 to oral antibiotic, and 37 to topical antibiotic). Mean (SD) baseline Patient Oriented Eczema Measure scores were 13.4 (5.1) for the control group, 14.6 (5.3) for the oral antibiotic group, and 16.9 (5.5) for the topical antibiotic group. At baseline, 104 children (93%) had 1 or more of the following findings: weeping, crusting, pustules, or painful skin. Mean (SD) POEM scores at 2 weeks were 6.2 (6.0) for control, 8.3 (7.3) for the oral antibiotic group, and 9.3 (6.2) for the topical antibiotic group. Controlling for baseline POEM score, neither oral nor topical antibiotics produced a significant difference in mean (95% CI) POEM scores (1.5 [-1.4 to 4.4] and 1.5 [-1.6 to 4.5] respectively). There were no significant differences in adverse effects and no serious adverse events. CONCLUSIONS: We found rapid resolution in response to topical steroid and emollient treatment and ruled out a clinically meaningful benefit from the addition of either oral or topical antibiotics. Children seen in ambulatory care with mild clinically infected eczema do not need treatment with antibiotics.

Population pharmacokinetics of rifampicin in adult patients with osteoarticular infections: interaction with fusidic acid.

AIMS: Rifampicin represents the key antibiotic for the management of osteoarticular infections. An important pharmacokinetic variability has already been described, particularly for absorption and metabolism. All previous pharmacokinetic studies have been focused only on patients treated for tuberculosis. The objective of the present study was to describe a population pharmacokinetic model of rifampicin in patients with staphylococcal osteoarticular infections, which has not been investigated to date. METHOD: Rifampicin concentrations were collected retrospectively from 62 patients treated with oral rifampicin 300 mg three times daily. Plasma concentration-time data were analysed using NONMEM to estimate population pharmacokinetic parameters. Demographic data, infection characteristics and antibiotics taken in addition to rifampicin antibiotics were investigated as covariates. RESULTS: A one-compartment model, coupled to a transit absorption model, best described the rifampicin data. Fusidic acid coadministration was identified as a covariate in rifampicin pharmacokinetic parameters. The apparent clearance and apparent central volume of distribution mean values [95% confidence interval (CI)] were 5.1 1 h-1 (1.2, 8.2 1 h-1 )/23.8 l (8.9, 38.7 l) and 13.7 1 h-1 (10.6, 18.0 1 h-1 )/61.1 1 (40.8, 129.0 1) for patients with and without administration of fusidic acid, respectively. Interindividual variability (95% CI) in the apparent clearance and apparent central volume of distribution were 72.9% (49.5, 86.0%) and 59.1% (5.5, 105.4%), respectively. Residual variability was 2.3 mg l-1 (1.6, 2.6 mg l-1 ). CONCLUSION: We developed the first population pharmacokinetic model of rifampicin in patients with osteoarticular infections. Our model demonstrated that fusidic acid affects rifampicin pharmacokinetics, leading to potential high drug exposure. This finding suggests that fusidic acid dosing regimens should be reconsidered.

An unusual case of folliculitis spinulosa decalvans.

We report the case of a 24-year-old man who presented with pustules, atrophic scars, and alopecia on the scalp, along with follicular keratotic papules on the cheeks, chest, abdomen, back, lateral upper arms, thighs, and axillae, of 6 years' duration. A diagnosis of folliculitis spinulosa decalvans (FSD) was made based on the clinical manifestation and histopathological findings. Dental examination also revealed dental anomalies and a fissured tongue, which are not known to be related to FSD. We provide an overview of the characteristic findings of FSD as well as a review of previously reported cases.

Where to from here? The treatment of impetigo in children as resistance to fusidic acid emerges.

Admissions for skin and soft-tissue infections have been increasing steadily in children and in the general population. Concerns have been raised recently about the increasing widespread use of topical fusidic acid and concurrent increase of fusidic acid-resistant Staphylococcus aureus. Fusidic acid resistance and methicillin resistant Staphylococcus aureus (MRSA) are both more prevalent in youngest age group (<5 year-olds) and particularly in the North island. In New Zealand, fusidic acid is recommended for treatment of minor impetigo and is the only fully-funded topical antibiotic. The evidence base for alternative treatment strategies for mild impetigo is limited. Most children with impetigo in the current Counties Manukau skin and sore throat schools programme received care with wound management with only a few requiring escalation. An upcoming randomised controlled trial comparing topical hydrogen peroxide cream, topical fusidic acid and wound management only (clean and cover) will help provide evidence about the effectiveness of alternative treatments in the New Zealand setting.
