Testis sparing management of tuberculous epididymitis - Case report.

Tuberculous epididymitis is uncommonly encountered and is a very rare complication of Bacillus Calmette-Guérin (BCG) intravesical therapy for the treatment of bladder urothelial cancer. With the increased use of BCG, it is conceivable that practicing urologists will see more patients presenting with this infection. Herein, we describe an unusual presentation of tuberculous epididymitis treated successfully in a conservative fashion with anti-tuberculotic medications and describe current diagnostic, as well as medical and surgical management strategies.

Invasive Fungal Diseases in Hospitalized Patients with COVID-19 in Israel: A Multicenter Cohort Study.

Highly variable estimates of COVID-19-associated fungal diseases (IFDs) have been reported. We aimed to determine the incidence of clinically important fungal diseases in hospitalized COVID-19 patients during the first year of the pandemic. We performed a multicenter survey of IFDs among patients hospitalized with COVID-19 in 13 hospitals in Israel between February 2020 and May 2021. COVID-19-associated pulmonary mold disease (PMD) and invasive candidiasis (IC) were defined using ECMM/ISHAM and EORTC/MSG criteria, respectively. Overall rates of IC and PMD among patients with critical COVID-19 were 10.86 and 10.20 per 1000 admissions, respectively, with significant variability among medical centers. PMD rates were significantly lower in centers where galactomannan was a send-out test versus centers with on-site testing (p = 0.035). The 30-day mortality rate was 67.5% for IC and 57.5% for PMD. Treatment with an echinocandin for IC or an extended-spectrum azole for PMD was associated with significantly lower mortality rates (adjusted hazard ratio [95% confidence interval], 0.26 [0.07-0.91] and 0.23 [0.093-0.57], respectively). In this multicenter national survey, variable rates of PMD were associated with on-site galactomannan testing, suggesting under-detection in sites lacking this capacity. COVID-19-related IFDs were associated with high mortality rates, which were reduced with appropriate antifungal therapy.

Erythropoietin administration is associated with improved T-cell properties in patients with myelodysplastic syndromes.

The immune system is impaired in myelodysplastic syndromes (MDS) and plays a role in the pathogenesis of the disease. Here we show effects of recombinant human erythropoietin (rHuEPO) on T cell (CD4+, CD8+ and CD4+CD25+) number and function in MDS patients. Healthy (20 subjects), MDS patients without rHuEPO treatment ('MDS', 13), and MDS patients treated with rHuEPO ('MDS+EPO', 17) were examined. CD4+ and CD8+ T cell numbers were reduced and increased respectively in MDS compared to healthy subjects. EPO treatment normalized these levels. CD4+CD25+ cell numbers, lower in MDS, were normalized in MDS+EPO. In vitro activation of CD4+ and CD8+ cells with phytohemagglutinin as measured by CD69 expression, demonstrated a 7.2 fold increase in CD4+ activation vs 13.6 fold for MDS and MDS+EPO respectively (p=0.004); and 10.2 fold (MDS) vs 18.6 fold (MDS+EPO, p<0.003) for CD8+ T cells. Expression of the co-stimulatory marker CD28, decreased in CD4+ and CD8+ T cells in MDS, was normalized in MDS+EPO CD4+ T cells. Subgroup analysis of milder disease (WHO RA and RARS) and more advanced disease revealed no difference in CD4+ and CD8+ T cell numbers. However, the activation of these cells in the RA/RARS subgroup was impaired in EPO-untreated and enhanced in EPO-treated MDS patients. Our data suggest that EPO treatment improves immune abnormalities in MDS and may depend on disease severity.
