Investigating disease severity in an animal model of concurrent babesiosis and Lyme disease.

Investigating disease severity in an animal model of concurrent babesiosis and Lyme disease. Int J Parasitol. 2018 Oct 24;: Authors: Bhanot P, Parveen N Abstract The incidence of babesiosis, Lyme disease and other tick-borne diseases has increased steadily in Europe and North America during the last five decades. Babesia microti is transmitted by species of Ixodes, the same ticks that transmit the Lyme disease-causing spirochete, Borrelia burgdorferi. B. microti can also be transmitted through transfusion of blood products and is the most common transfusion-transmitted infection in the U.S.A. Ixodes ticks are commonly infected with both B. microti and B. burgdorferi, and are competent vectors for transmitting them together into hosts. Few studies have examined the effects of coinfections on humans and those have had somewhat contradictory results. One study linked coinfection with B. microti to a greater number of symptoms of overall disease in patients, while another report indicated that B. burgdorferi infection either did not affect babesiosis symptoms or decreased its severity. Mouse models of infection that manifest pathological effects similar to those observed in human babesiosis and Lyme disease offer a unique opportunity to thoroughly investigate the effects of coinfection on the host. Lyme disease has been studied using the susceptible C3H mouse infection model, which can also be used to examine B. microti infection to understand pathological m...

Toxoplasma gondii, a protozoan parasite, undergoes a complex and poorly understood developmental process that is critical for establishing a chronic infection in its intermediate hosts. Here, we applied single-cell RNA-sequencing (scRNA-seq) on>5,400 Toxoplasma in both tachyzoite and bradyzoite stages using three widely studied strains to construct a comprehensive atlas of cell-cycle and asexual development, revealing hidden states and transcriptional factors associated with each developmental stage. Analysis of SAG1-related sequence (SRS) antigenic repertoire reveals a highly heterogeneous, sporadic expression pattern ...

AbstractThe present study evaluated the in vitro efficacy of miltefosine against cysts ofAcanthamoeba spp. belonging to genotypes T3, T4 and T5. Each genotype was incubated with miltefosine at the concentration of 2.42, 4.84, 9.68, 19.36, 38.72 and 77.44  mM for different periods; 1, 3, 5, 7 d at 37 °C. The viability was assessed by staining with 0.4% trypan blue and culturing on NNA medium at 30 °C for 1 month. The results showed 100% eradication of cyst stage of all concentrations, but exhibited a different degree of activity against differe nt genotypes. The MCC of 38.72 mM could kill ge...

This study assessed treatment patterns and healthcare resource utilization (HRU) of patients with severe aplastic anemia (SAA) with insufficient response to immunosuppressive therapy (IST). A retrospective chart review was conducted at Dana-Farber Cancer Institute (DFCI), United States, and H ôpital Saint-Louis (HSL), France. Eligible patients were ≥ 18 years old, diagnosed with acquired SAA between January 1, 2006, and July 31, 2016, had insufficient response to IST, and had ≥ 12 months of follow-up post-diagnosis. Overall survival (OS) was estimated using the Kaplan-Meier method. Among the 40 patients, mean a...

AbstractFanconi anemia (FA) is a DNA repair disorder resulting from mutations in genes encoding for FA DNA repair complex components and is characterized by variable congenital abnormalities, bone marrow failure (BMF), and high incidences of malignancies. FA mosaicism arises from reversion or other compensatory mutations in hematopoietic cells and may be associated with BMF reversal and decreased blood cell sensitivity to DNA-damaging agents (clastogens); this sensitivity is a phenotypic and diagnostic hallmark of FA. Uncertainty regarding the clinical significance of FA mosaicism persists; in some cases, patients have sur...

This study aimed to assess a comprehensive prevalence of most frequent thalassemia mutations in Khuzestan Province, where is a belt of thalassemia in Iran. A total of 6946 subjects were enrolled for evaluating alpha-beta thalassemia from 2012 to 2018. In order to determine the silent mutations, subjects with microcytic hypochromic without anemia with normal Hb, HbA2, and HbF were included too. Genomic DNA was extracted, and ARMS-PCR, Gap-PCR, and DNA sequencing were used to detect thalassemia mutations. Of 6946 individuals, just 880 (12.6%) were normal, and 6066 (87.3%) were the carrier for thalassemia. The most frequent p...

AbstractSplenomegaly is a key clinical manifestation of myelofibrosis, and splenectomy is currently indicated in patients with drug refractory, symptomatic splenomegaly or with the aim of improving refractory cytopenias. Transformation to acute myeloid leukemia occurs in up to 20% of patients with myelofibrosis, while cases of myeloid sarcoma have been reported very unfrequently. In this manuscript, we report the case of a 60-year-old man with a history of primary myelofibrosis who underwent splenectomy because of drug-refractory massive splenomegaly, systemic symptoms and anemia. At the opening of the peritoneal cavity, t...

We present the current portfolio of next-generation anti-Wolbachia candidates discovered through phenotypic screening of chemical libraries and validated in a range of in vitro and in vivo filarial infection models. Several novel chemotypes have been identified with selected narrow-spectrum anti-Wolbachia specificity and superior time-to-kill kinetics compared with doxycycline. We discuss the opportunities of developing these novel anti-Wolbachia agents as either cures, adjunct therapies or new preventatives for the treatment of veterinary filariasis.

We present the case of a 59-year-old patient with malabsorption syndrome which started with polyneuropathy. Capsule endoscopy and enteroscopy show villous denudation. Histological study confirms diaphragm disease of the small bowel. Diaphragm disease is a rare disease characterized by the presence of multiple thin diaphragms, such as septa, that narrow the intestinal lumen. The clinical features can be iron deficiency anemia, intestinal obstruction, change in bowel habits or acute abdomen secondary to perforation. It is usually generally with sustained use of high doses of non-steroidal anti-inflammatory drugs. The diagnos...

Authors: Fernández Conesa M, Milena Muñoz A, Valero González MÁ Abstract We read with interest the article by Guido Villa-Gómez, Manuel Alejandro Mahler and Dante Manazzoni "A new case of pseudoaneurysm of the right hepatic artery secondary to laparoscopic cholecystectomy". A 57-year-old cholecystectomized female was admitted due to abdominal pain with an analytical pattern of cholestasis and liver enzyme alterations, with cholangitis that progressed to septic shock of a biliary origin with gradual anemia and hypotension.
