Chronic urticaria (CU) is characterized by repeated occurrence of wheals or itching for more than 6 weeks. When urticaria symptoms repeatedly occur despite taking Western medicines such as antihistamines, Chinese medicine (CM) has been shown to relieve symptoms and prevent recurrence. However, the lack of robust evidence from the evidence-based medicine perspective is hindering acceptance of CM by the Western medicine community. In recent years, more and more evidence-based studies of CU treatment by CM were report in English literatures, including acupuncture, herbs, and food, although some of evidence is still with low quality. These progress in CM treatment of CU will inspire high quality evidences via randomized, controlled trials assessing effificacy and safety of CM treatment of CU.

Primary cutaneous cryptococcosis (PCC) has been confirmed as a distinct clinical entity with secondary cutaneous cryptococcosis from systematic infection since 2003. Although it has been confirmed as a distinct clinical entity, little has progressed on PCC in immunocompetent hosts compared to their immunocompromised counterpart. We reviewed the literature on cases of PCC in immunocompetent patients from 2004 to 2014, and 21 cases from 16 reports were identified. Males are more likely to develop PCC infections, with a ratio of 17:4 male to female. These patients were found to be almost all senior population except for patients from Asia. Asymptomatic or moderate itching manifesting in a painful nodule is the most common presentation, although there is no typical clinical manifestation recorded. Upper limbs are the most common site of infection, accounting for 71.4 % of all patients. Of the 12 identified isolates, 6 strains are identified as C. neoformans, 5 as C. gattii, and 1 as C.laurentii. Fluconazole was used in 10 cases; however, only 80 % of the 10 cases could confirm that fluconazole was effective in clearing the infections. Interestingly although not approved as a treatment option, Itraconazole was effective in the seven cases it was used to treat cryptococcosis, with a dosage range of 100-400 mg/d and duration from 3 to 6 months. Even though the prognosis of these patients was generally good, more data are need to determine which antifungal azole is the better treatment option and whether primary skin infections could disseminate to systematic infection.

To summarize the epidemiology, clinical features, treatment, and outcome of cryptococcal meningitis (CM) in autoimmune hemolytic anemia (AIHA) patients and to provide a reference for the prevention and control of AIHA complicated with CM, we evaluated five cases of CM in patients with AIHA treated in our hospital from 2003 to 2013 and eight related foreign cases. All of the clinical isolates were Cryptococcus neoformans var. grubii and grouped into the VNI genotype and serotype A. The clinical features exhibit significant features. Headache, nausea, and fever are common symptoms of AIHA complicated with CM. The early clinical manifestations lack specificity, which may lead to delayed diagnosis and treatment. Long-term use of prednisone (≥15 mg day−1), poor control of anemia, and splenectomy are risk factors for AIHA complicated with cryptococcal infection. The combination of intravenous amphotericin B and oral 5-fluorocytosine remains the preferred treatment for AIHA complicated with CM.

Amphotericin B deoxycholate (AmB), a classic antifungal drug, remains the initial treatment of choice for deep fungal infections, but it is not appropriate for treatment of cryptococcal meningitis due to its inability to pass through the blood–brain barrier (BBB). We examined the efficacy of amphotericin B-polybutylcyanoacrylate nanoparticles (AmB-PBCA-NPs) modified with polysorbate 80 that had a mean particle diameter less than 100 nanometers (69.0 ± 28.6 nm). AmB-PBCA-NPs were detected in the brain 30 minutes after systemic administration into BALB/c mice and had a higher concentration than systemically administered AmB liposome (AmB-L, P < 0.05); AmB was not detected in the brain. Following infection for 24 hours and then 7 days of treatment, the survival rate of mice in the AmB-PBCA-NP group (80%) was significantly higher than that of the AmB (0%) or AmB-L (60%) treatment groups. Fungal load was also lower when assessed by colony-forming unit counts obtained after plating infected brain tissue (P < 0.05). Our study indicates that AmB-PBCA-NPs with polysorbate 80 coating have the capacity to transport AmB across the BBB and is an efficient treatment against cryptococcal meningitis in a mouse model.
Objective To study the epidemiology and clinical features of primary cutaneous cryptococcosis from 2000 to 2008.Methods Cases of primary cutaneous cryptococcosis from 2000 to 2008 were retrospectively analysed and the differences with those between 1985 and 2000 were compared.Results PCC occurred more commonly in the older and the male in the recent 8 years.There was no difference in the onset between immunocompetent and immunocompromised hosts,while HIV positive patients had the lower probability to get PCC,xternal injury might be the important causative factors,erythra still happened majorly in extremities or other exposure sites,the erythra had changed from whitlow or cellulitis to ulcer,nodus,erythema,and so on,the oral antifungal drugs combined with surgery were most acceptable treatment and fluconazole was still the first choice for PCC,and the prognosis was good.Conclusions In recent years,PCC obtained some new characteristics.We considered that the immune state affected less or had no effect on incidence of PCC,while majorly affected the final outcome of Cryptococcus infection.
Objective To investigate the effect of Cryptococcus neoformans on the viability of keratinocytes.Methods Strains of Cryptococcus neoformans B3501 and its acapsule mutant cap64 were cocultured with keratinocytes and the viability of the keratinocytes was measured by flow cytometry after 0.5 h,1 h and 2 h.Results were compared with those of negative control,hear-killed fungi,and the fungi indirectly contacted with keratinocytes.Results Viability of keratinocytes decreased significantly cocultured with Cryptococcus neoformans by time prolonging,while more significantly after 1 h and 2 h's coculture with B3501.There was no difference in the viability of keratinocytes between coculture with killed B3501 and indirect coculture with B3501.Conclusions Capsule of Cryptococcus neoformans plays an important role in viability of keratinocytes.Indirect contact with Cryptococcus neoformans is necessary for viability decreasing.
SummaryCryptococcus neoformans is a medically important fungus and can infect all the organs of the body. As vascular endothelial cell is an important target for C. neoformans to penetrate any organs, the differential protein expression of human umbilical vascular endothelial cell (HUVEC) after incubating with C. neoformans may be the key to penetration. The proteins of HUVECs incubated with C. neoformans and normal HUVECs were collected and purified. After two‐dimensional electrophoresis, the differential protein expression was identified by matrix‐assisted laser desorption/ionisation mass spectrometry. The mRNA levels of some proteins were measured by real‐time PCR. Three proteins were found significantly overexpressed in HUVECs incubated with C. neoformans, and nine other proteins were downregulated. The mRNA levels of S100A10 and peroxiredoxin I fluctuated with the protein levels. These results suggested that the expressions of peroxiredoxin I and S100A10 were regulated during the process of invasion of HUVECs by C. neoformans. We hypothesise that these proteins take part in the modifications of HUVEC cytoskeleton and the tolerance to oxidative stress, which may affect the process of invasion by C. neoformans.
