Multidrug-Resistant Candida auris Fungemia in Critical Care Units: Experience from a Tertiary Care Hospital in India.

Candida auris, a recently identified multiresistant Candida species, was first reported in Japan in 2009. It is different from other pathogenic yeast species because of its propensity to cause outbreaks and transmits between patients within health care settings. The invasive infections caused by C. auris are associated with high mortality rates, approaching 70% particularly in intensive care unit patients. Conventional biochemical methods are inaccurate in identifying this species of Candida. Although C. auris is frequently reported as multi-, extended-, or pan drug resistant to antifungal drugs, there is a wide variability in the susceptibility among reports worldwide. In this study we report a case series of five hospitalized patients with multidrug-resistant candidemia caused by C. auris in a tertiary hospital in India. Our finding suggests that correct identification followed by therapeutic intervention is necessary for favorable outcome in patients with C. auris fungemia.

Oxidative stress in chronic pancreatitis: pathophysiological relevance and management.

SIGNIFICANCE: Chronic pancreatitis (CP) is a progressive, inflammatory disease of the pancreas leading to slow destruction of pancreatic parenchyma and progressive fibrosis. The pathophysiological mechanism of CP is not well understood. RECENT ADVANCES: A pathophysiologic role of oxidative stress in CP has, however, been suggested in recent years. Pancreatic acinar cells contain phase I cytochrome P450 (CYP 450) biotransforming enzymes and phase II conjugation reactions for the metabolism of xenobiotics. The oxidative stress in the acinar cell may result from generation of free radicals through CYP induction, concurrent exposure to a chemical that undergoes bioactivation, and insufficiency of micronutrients that are required to sustain antioxidant (AO) capacity. CRITICAL ISSUES: Studies have shown that there is indeed a state of oxidative stress as evidenced by increased levels of products of oxidative stress and reduced AO capacity in patients with CP. A recent randomized, controlled trial has shown beneficial effect of AO therapy in CP; a combination of AOs (0.54 g ascorbic acid, 9000 IU ß-carotene, 270 IU α-tocopherol, 600 µg organic selenium, and 2 g methionine per day in divided doses) led to significant reductions in pain and oxidative stress in patients with CP. FUTURE DIRECTIONS: Similar studies from other centers and multicenter studies should confirm that oxidative stress plays an important role in the pathophysiology of CP and supplementation with AOs leads to significant pain relief in patients with this disease.

A randomized controlled trial of antioxidant supplementation for pain relief in patients with chronic pancreatitis.

BACKGROUND & AIMS: Oxidative stress has been implicated in the pathophysiology of chronic pancreatitis (CP). We evaluated the effects of antioxidant supplementation on pain relief, oxidative stress, and antioxidant status in patients with CP. METHODS: In a placebo-controlled double blind trial, consecutive patients with CP were randomized to groups that were given placebo or antioxidants for 6 months. The primary outcome measure was pain relief, and secondary outcome measures were analgesic requirements, hospitalization, and markers of oxidative stress (thiobarbituric acid-reactive substances [TBARS]) and antioxidant status (ferric-reducing ability of plasma [FRAP]). RESULTS: Patients (age 30.5+/-10.5 years, 86 male, 35 alcoholic, and 92 with idiopathic CP) were assigned to the placebo (n=56) or antioxidant groups (n=71). After 6 months, the reduction in the number of painful days per month was significantly higher in the antioxidant group compared with the placebo group (7.4+/-6.8 vs 3.2+/-4, respectively; P< .001; 95% CI, 2.07, 6.23). The reduction in the number of analgesic tablets per month was also higher in the antioxidant group (10.5+/-11.8 vs 4.4+/-5.8 respectively; P= .001; 95% CI, 2.65, 9.65). Furthermore, 32% and 13% of patients became pain free in the antioxidant and placebo groups, respectively (P= .009). The reduction in the level of TBARS and increase in FRAP were significantly higher in the antioxidant group compared with the placebo group (TBARS: placebo 1.2+/-2.7 vs antioxidant 3.5+/-3.4 nmol/mL; P= .001; 95% CI 0.96, 3.55; FRAP: placebo -5.6+/-154.9 vs antioxidant 97.8+/-134.9 microMFe(+2) liberated, P= .001, 95% CI 44.98, 161.7). CONCLUSIONS: Antioxidant supplementation was effective in relieving pain and reducing levels of oxidative stress in patients with CP.

Dietary counseling versus dietary supplements for malnutrition in chronic pancreatitis: a randomized controlled trial.

BACKGROUND & AIMS: Up to 50% of patients with chronic pancreatitis (CP) are malnourished. There are limited data on the role of dietary intervention in improving the nutritional status of such patients. The aim was to compare the efficacy of medium chain triglyceride (MCT)-enriched commercial dietary supplements with dietary counseling for homemade food in the management of malnutrition in patients with CP. METHODS: In a randomized controlled trial, consecutive undernourished patients with CP (body mass index [BMI] <18.5 kg/m(2)) at a tertiary care hospital were randomized to receive either dietary counseling for regular homemade food or commercial MCT-enriched dietary supplements for a period of 3 months to compensate for the dietary calorie deficit. All patients received standard management for CP including pancreatic enzyme supplements. Primary outcome measure was improvement in BMI. RESULTS: Sixty malnourished patients with CP were randomized to counseling group (n = 29; mean age, 32 +/- 10 years; male, 83%) and supplementation group (n = 31; mean age, 28 +/- 10 years; male, 84%). BMI increased in both the counseling group and supplementation group (17.2 +/- 1.7 vs 18.1 +/- 1.8 kg/m(2), P = .001; 16.7 +/- 1.6 vs 18.2 +/- 1.6 kg/m(2), P = .001). There were similar improvements in triceps skinfold thickness, dietary intake, fecal fat, and pain score during a period of 3 months in both groups. There was, however, no significant difference between the counseling and supplementation groups with regard to any of the outcome measures. CONCLUSIONS: Dietary counseling for a balanced homemade diet is as good as commercial food supplements in improving malnutrition in patients with CP.
