ABSTRACT

Schizophyllum commune is a well-known mushroom forming fungi which is an edible one due to its nutritive value. It exhibits a special wood degrading mechanism to grow in decay matters by releasing a series of enzymes. These enzymes might make them an opportunistic pathogen which has been reported to infect various animals and human beings too. Although these fungi were identified as human and animal pathogens, their mechanisms of pathogenesis and the key virulence factors involved in disease establishment are not known. In this study, we reported this fungal infection in freshwater fish for the first time and its morphological features. Further, we employed RNA-seq technique to identify the major virulence factors involved in the pathogenesis in fish and the network of interaction between the identified virulence factors were analysed. Also, we confirmed the virulence roles of this fungus during infection by qRT-PCR analysis. This study emphasizes the virulence nature of the common mushroom forming food fungus and the involvement of enzymes such as phosphoinositide phospholipase C, hexosaminidase and few toxins such as pesticidal and insecticidal crystal proteins which opened a new avenue in the virulence nature of edible mushrooms.

ABSTRACT

AIMS: To study the toxicity of ABVE-PC (doxorubicin, bleomycin, vincristine, etoposide, prednisone and cyclophosphamide) and modified-BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone) in intermediate-risk and high-risk Hodgkin lymphoma patients. METHODS: High-risk patients received 4 cycles of modified-BEACOPP (m-BEACOPP) plus 4 cycles of ABVD. Intermediate-risk patients received 4 cycles of ABVE-PC plus 2 cycles of ABVD. RESULTS: From 2010 to 2014, 17 patients received 66 cycles of m-BEACOPP and 9 patients received 40 cycles of ABVE-PC. In the m-BEACOPP and ABVE-PC courses, respectively, significant thrombocytopenia (<50,000/mm(3)) occurred in 10.6% vs 0% of courses; anemia (Hb. <8 gm/dl) in 27.3% vs 15%; neutropenia (ANC<500/mm(3)) in 46.9% vs 32.5%; and febrile neutropenia in 33.3% vs. 22.5%. Only episode of documented infection (hepatic abscess) occurred in ABVE-PC. There were no episodes of sepsis, typhlitis or pneumonia in either group. All 26 patients are in remission with a median follow-up of 35 months (range, 17-61); and there have been no relapses. Two of 26 (7.7%) patients failed to achieve rapid early response after 2 cycles and complete remission after 4 cycles of chemotherapy; both achieved remission with more intensive regimens followed by radiation. The remaining 24 patients did not receive radiation therapy. CONCLUSIONS: Both m-BEACOPP and ABVE-PC regimens have acceptable toxicity; and thus can be used in most centres with optimum supportive care facilities. They offer promising response rate and relapse free survival without the need for radiation therapy in most patients; and thus may be considered for children with high-risk and intermediate-risk Hodgkin lymphoma.

ABSTRACT

Glutaric acidemia type 1 (GA1) is a rare inherited metabolic disorder which goes underdiagnosed due to its latency period and subtle presentation. A pilot clinical study was conducted to assess the usefulness, specificity and sensitivity of the tandem mass (MS/MS) spectrometer, specifically the Abbott (AB) Sciex 3200, in the screening for GA1 using dried blood spots. A total of 17,100 specimens, comprising pediatric patients and healthy newborns, were screened from June 2012 to June 2014. A selection criterion was applied to increase the range of samples tested. 14 of the total specimens tested presumptive positive for GA1, of whom all were symptomatic. The diagnosis was confirmed in 4 of the 14 cases and they were started on treatment. 4 cases expired before confirmation. The remaining cases were empirically started on treatment. Most of the patients responded favorably to the dietary management. One important observation was that the older symptomatic children diagnosed with GA1 had poorer outcomes in terms of recovery of delayed milestones and mental deterioration, further emphasizing the need for early diagnosis of organic acidemias along with the other biochemical defects. Tandem mass spectrometry was found to be more than 93.33% sensitive and more than 99.42% specific. The screening test proved to be very simple and economical.
