Abstract
Obtaining Plasmodium vivax sporozoites is essential for in vitro culture of liver stage parasites, not only to understand fundamental aspects of parasite biology, but also for drug and vaccine development. A major impediment to establish high-throughput in vitro P. vivax liver stage assays for drug development is obtaining sufficient numbers of sporozoites. To do so, female anopheline mosquitoes have to be fed on blood from P. vivax-infected patients through an artificial membrane-feeding system, which in turns requires a well-established Anopheles colony. In this study we established conditions to provide a robust supply of P. vivax sporozoites. Adding a combination of serum replacement and antibiotics to the membrane-feeding protocol was found to best improve sporozoite production. A simple centrifugation method appears to be a possible tool for rapidly obtaining purified sporozoites with a minimal loss of yield. However, this method needs to be better defined since sporozoite viability and hepatocyte infection were not evaluated.

Abstract
Patients infected by the SARS-CoV-2 virus are commonly diagnosed with threatening liver conditions associated with drug-induced therapies and systemic viral action. RNA-Seq data from cells in bronchoalveolar lavage fluid from COVID-19 patients have pointed out dysregulation of kallikrein-kinin and renin-angiotensin systems as a possible mechanism that triggers multi-organ damage away from the leading site of virus infection. Therefore, we measured the plasma concentration of biologically active peptides from the kallikrein-kinin system, bradykinin and des-Arg9-bradykinin, and liver expression of its proinflammatory axis, bradykinin 1 receptor (B1R). We measured the plasma concentration of bradykinin and des-Arg9-bradykinin of 20 virologically confirmed COVID-19 patients using a liquid chromatography-tandem mass spectrometry-based methodology. The expression of B1R was evaluated by immunohistochemistry from post-mortem liver specimens of 27 COVID-19 individuals. We found a significantly higher blood level of des-Arg9-bradykinin and a lower bradykinin concentration in patients with COVID-19 compared to a healthy, uninfected control group. We also observed increased B1R expression levels in hepatic tissues of patients with COVID-19 under all hepatic injuries analyzed (liver congestion, portal vein dilation, steatosis, and ischemic necrosis). Our data indicate that des-Arg9-bradykinin/B1R is associated with the acute hepatic dysfunction induced by the SARS-CoV-2 virus infection in the pathogenesis of COVID-19.

Abstract
Background Over a third of the world’s population is at risk of Plasmodium vivax-induced malaria. The unique aspect of the parasite’s biology and interactions with the human host make it harder to control and eliminate the disease. Glucose-6-phosphate dehydrogenase (G6PD) deficiency and Duffy-negative blood groups are two red blood cell (RBC) variations that can confer protection against malaria. Methods Molecular genotyping of G6PD and Duffy variants was performed in 225 unrelated patients (97 with uncomplicated and 128 with severe vivax malaria) recruited at a Reference Centre for Infectious Diseases in Manaus. G6PD and Duffy variants characterizations were performed using Real Time PCR (qPCR) and PCR–RFLP, respectively. Results The Duffy blood group system showed a phenotypic distribution Fy(a + b−) of 70 (31.1%), Fy(a + b +) 96 (42.7%), Fy(a−b +) 56 (24.9%) and Fy(a−b−) 1 (0.44%.) The genotype FY*A/FY*B was predominant in both uncomplicated (45.3%) and severe malaria (39.2%). Only one Duffy phenotype Fy(a-b) was found and this involved uncomplicated vivax malaria. The G6PD c.202G > A variant was found in 11 (4.88%) females and 18 (8.0%) males, while c.376A > G was found in 20 females (8.88%) and 23 (10.22%) male patients. When combined GATA mutated and c.202G > A and c.376A > G mutated, was observed at a lower frequency in uncomplicated (3.7%) in comparison to severe malaria (37.9%). The phenotype Fy(a−b +) (p = 0.022) with FY*B/FY*B (p = 0.015) genotype correlated with higher parasitaemia. Conclusions A high prevalence of G6PD c202G > A and c.376A > G and Duffy variants is observed in Manaus, an endemic area for vivax malaria. In addition, this study reports for the first time the Duffy null phenotype Fy(a-b-) in the population of the Amazonas state. Moreover, it is understood that the relationship between G6PD and Duffy variants can modify clinical symptoms in malaria caused by P. vivax and this deserves to be further investigated and explored among this population.

Abstract
Abstract
Background
Life expectancy of people living with HIV (PLHIV) has been increasing since the advent of antiretroviral therapy. However, prevalence of non-communicable diseases (NCD) and associated deaths has followed the same trend. From these NCDs, those of cardiovascular origin have become the most prevalent among PLHIV.
Purpose
In this study we delineate a cascade of care for hypertension screening, diagnosis, treatment, drug adherence and control in PLHIV.
Methods
Male and female patients diagnosed with HIV above 40 years of age attending to an outpatient clinic of a reference tertiary care centre for infectious diseases were cross-sectionally screened for hypertension through blood pressure (BP) measurement during outpatient consultation.
Results
A total of 298 subject were enrolled. Of these, 107 (35.9%) presented elevated BP consistent with hypertension according to national guidelines. Of these, only 36 (33.6%) were aware of the diagnosis, 19 (17.7%) were on regular cardiological follow-up, 17 (15.8%) were under treatment and 11 (10.2%) responded to be adherent to BP lowering medication.
Care Cascade HIV_HTN
Conclusions
Steep decline was revealed in several steps of the cascade of care, especially regarding the awareness level. Integrative methods for NCD and HIV care are urgently needed. Early screening of hypertension, diagnosis, treatment, adherence and ongoing BP control should be equal targets in HIV care. Finally, there is an urgent need to encourage HIV primary care and infectious disease health professionals to early screen for cardiovascular outcomes.

Abstract
We describe a rare case of idiopathic thrombocytopenic purpura (ITP) triggered by Plasmodium vivax infection. The patient developed thrombocytopenia and bleeding associated with three episodes of malaria, and became dependent on corticosteroid therapy. The mechanisms by which this parasite evokes thrombocytopenia remain obscure.
