A series of curcumin bis-conjugates 3a-q, 5a-k and 6a-k were synthesized in good yields utilizing an optimized reaction condition. We explored the effect of different amino acids and protecting groups on biological activities of curcumin. The conjugates were screened for anti-inflammatory, analgesic and antimicrobial properties. Some of the conjugates showed promising biological observations with a potency comparable with the standard references. The variations in biological properties concerning different amino acids and protecting groups are interesting observations. Effects of the synthesized conjugates on splenocytes and the production of nitric oxide by lipopolysaccharide-stimulated peritoneal macrophages are correlated with the observed anti-inflammatory properties. We have also established the safety profile of the most active conjugates. Robust 2D-QSAR studies supported and validated biological data.

Visceral leishmaniasis (VL) is a public health threat for several tropical countries, including Brazil. Therapy failures and relapses aggravate VL morbidity and mortality. Our study aimed at identifying predictors of relapse and thus contributes to directing therapeutic options and patient follow-up.. A nonconcurrent cohort of 571 subjects who completed successful therapy for VL in the city of Bauru, São Paulo State, Brazil, was followed for 24 months in order to identify the incidence and predictors of relapse. Extensive review of medical charts and laboratory files was conducted. Univariate and multivariable Cox regression models were used to identify predictors for the outcome of interest. A hierarchical strategy was used for variable selection in multivariable models.. Relapses occurred in 6.8% of treated subjects, after a median of 6 months (interquartile range, 4-9). In a comprehensive multivariable model, relapse was associated with: HIV-coinfection (hazard ratio [HR], 7.47; 95% confidence interval [CI], 2.58-21.55); the presence of lower limb edema (HR, 6.06; 95%CI, 1.38-26.77) and low platelet count upon admission (HR for platelet count × 1000, 0.99; 95%CI, 0.98-0.99) ; and secondary pneumonia (HR, 5.49; 95%CI, 1.49-20.18). On the other hand, therapy with Liposomal Amphotericin (as opposed to Antimoniate) was not independently associated with relapse (HR, 5.97; 95%CI, 0.63-56.29).. Besides reinforcing the impact of HIV coinfection on the outcome of VL, our study points to clinical and laboratory findings that characterize patients who were more likely to relapse. Those groups should be more closely followed, and possibly could benefit from novel therapeutic options.

To characterize the clinical and epidemiological profiles of patients with visceral leishmaniasis (VL) treated with liposomal amphotericin B (LAmB) and to identify prognostic factors for death from VL in 2008-2012 in the state of Minas Gerais, Brazil.. A historical cohort study was conducted using data obtained from treatment requests forms, Brazilian Notifiable Disease Information System and the Mortality Information System. Case-fatality rates of patients with VL treated with LAmB were compared with patients treated with other therapies. Logistic regression analysis was used to identify prognostic factors for death.. The overall case-fatality rate of the 577 patients treated with LAmB was 19.4%. Prognostic factors for death from VL were age between 35 and 49 years (OR 2.7; 95% CI 1.3-5.4) and above 50 years (OR 2.6; 95% CI 1.3-4.9), jaundice (OR 2.2; 95% CI 1.2-3.7), kidney disease (OR 2.8; 95% CI 1.6-4.9), presence of other infections (OR 2.4; 95% CI 1.5-4.1), edema (OR 2.0; 95% CI 1.1-3.4), platelet count below 50.000/mm3 (OR 3.6; 95% CI 2.1-6.0), AST higher than 100 U/L (OR 2.2; 95% CI 1.3-3.8), and assistance in non-specialized institutions (OR 1.9; 95% CI 1.0-3.5).. Case-fatality rates were higher than that observed among patients with VL treated with other therapies. Identification of prognostic factors of death from VL may allow early diagnosis of patients prone to such outcome and prompt an expeditious and appropriate management of VL to reduce fatality rates.

Current Letter presents design, synthesis and biological evaluation of a novel series of pyrazolylthiazole carboxylates 1a-1p and corresponding acid derivatives 2a-2p. All 32 novel compounds were tested for their in vivo anti-inflammatory activity by carrageenan-induced rat paw edema method as well as for in vitro antimicrobial activity. All the tested compounds exhibited excellent AI activity profile. Three compounds 1p (R=Cl, R(1)=Cl), 2c (R=H, R(1)=F) and 2n (R=Cl, R(1)=OCH3) were identified as potent anti-inflammatory agents exhibiting edema inhibition of 93.06-89.59% which is comparable to the reference drug indomethacin (91.32%) after 3h of carrageenan injection while most of the other compounds displayed inhibition ⩾80%. In addition, pyrazolylthiazole carboxylic acids (2a-2p) also showed good antimicrobial profile. Compound 2h (R=OCH3, R(1)=Cl) showed excellent antimicrobial activity (MIC 6.25μg/mL) against both Gram positive bacteria comparable with the reference drug ciprofloxacin (MIC 6.25μg/mL).

Trichosporon (T.) asahii can cause superficial skin infections and can be an opportunistic pathogen that produces potentially fatal systemic infections in immunocompromised hosts. We report a case of lower limb infection due to T. asahii in an immunocompetent patient who displayed no evidence of underlying disease. There is a strong possibility that our patient had been colonized at the infection site as part of the normal skin flora. After one-month bed rest due to an accidental fall and fracture of the right shoulder blade, a 61-year-old woman experienced severe edema and redness in the right lower limb and received topical treatment with iodine solution and antibiotics without improvement. She presented at our Outpatient Clinic with cellulitis and lymphedema. Samples collected from the affected areas revealed T. asahii and the patient was referred to a hospital for infectious diseases for appropriate therapy. The patient was treated with wound dressings until she was admitted to our intensive care unit when her general condition abruptly deteriorated. Despite in vitro susceptibility results, therapy with liposomal amphotericin and voriconazole could not change the fatal outcome. Nowadays, physicians must suspect this emerging difficult-to-treat fungal pathogen and treatment must start promptly in these infections.

Fungal orbital infections are rare among children, especially in immunocompetent infants. Two infants presented to us with unilateral proptosis and swelling of the eyelids and periorbital area. Imaging showed an intraorbital mass causing proptosis and bony orbital expansion. There was no sinus, nasal, or intracranial involvement. Systemic evaluation did not reveal any evidence of a compromised immune system. A biopsy from the mass showed the presence of fungal infection. Both infants responded well to medical therapy with intravenous amphotericin B.

Rhinocerebral mucormycosis is a rapidly progressive and often fatal infection frequently seen in patients with uncontrolled diabetes mellitus and hematologic malignancies. The disease is difficult to diagnose because it often masquerades as bacterial sinusitis. The current report describes a 69-year-old white woman with diabetes mellitus who was prescribed high-dose prednisone therapy for chronic obstructive pulmonary disease. Two weeks after treatment initiation, she presented to the hospital with facial edema on the right side, mouth pain, and general weakness. No black eschars on the nasal mucosae or palates were present on admission. Although bacterial etiology was initially suspected, surgery and tissue samples revealed the presence of rhinocerebral mucormycosis. The patient died at 6 days postadmission despite aggressive medical and surgical intervention. The current report discusses the risk factors associated with rhinocerebral mucormycosis as well as the necessity of early diagnosis and treatment to improve patient outcomes.

The histopathological response of scrapie-infected hamsters treated at the late stage of the infection with an "anti-scrapie" drug, a polyene macrolide antibiotic designated MS-8209, was evaluated in the brain. The results showed that (1) MS-8209 prolonged significantly the incubation time of the experimental disease, (2) MS-8209 delayed the appearance of spongiosis and astrogliosis in the brain, (3) immunodetection of abnormal prion protein and glial fibrillary acidic protein was significantly reduced in the central nervous system. In addition, this report indicates that polyene antibiotics markedly delay the development of the classical brain lesions that result from scrapie infection.

Existing models of Candida albicans infection are semi-quantitative and do not allow continuous observations to be made on individual animals. We have used the inflammatory response in the footpad as an indirect measure of the number of yeast cells in a localised lesion. C. albicans infection of the footpad has been used in series of experiments in which changes in yeast-cell numbers in the local lesion have been compared with the degree of footpad oedema. Studies in animals treated with cyclophosphamide or amphotericin have confirmed that paw oedema parallels yeast-cell numbers in the local lesion. This quantitative approach will be helpful in the study of localised infection with C. albicans and other fungi and in the evaluation of antifungal agents.
