Dolutegravir/Lamivudine Is Noninferior to Continuing Dolutegravir- and Non-Dolutegravir-Based Triple-Drug Antiretroviral Therapy in Virologically Suppressed People With Human Immunodeficiency Virus: DUALING Prospective Nationwide Matched Cohort Study.

Background: Confirming the efficacy of dolutegravir/lamivudine in clinical practice solidifies recommendations on its use.

Methods: Prospective cohort study (DUALING) in 24 human immunodeficiency virus (HIV) treatment centers in the Netherlands. HIV RNA-suppressed cases were on triple-drug antiretroviral regimens without prior virological failure or resistance and started dolutegravir/lamivudine.

Lower plasma calcium associated with COVID-19, but not with disease severity: a two-centre retrospective cohort study.

Background: Previous studies indicate hypocalcaemia as a potential diagnostic and prognostic marker of corona-virus disease 2019 (COVID-19). Our aim was to investigate these relations in more detail in a large test cohort and an independent validation cohort.

Methods: We retrospectively included 2792 COVID-19 suspected patients that presented to the emergency department (ED) of two hospitals.

Flow cytometric analysis of viable bacteria in urine samples of febrile patients at the emergency department.

Background: Fast and reliable diagnostics are important in febrile patients admitted to the emergency department. Current urine diagnostics are fast but moderately reliable or reliable but time consuming. Flow cytometry (FC) is a new promising technique in the diagnostics of complicated urinary tract infections by counting bacteria in urine samples.

Effectiveness and cost-effectiveness of a nurse-delivered intervention to improve adherence to treatment for HIV: a pragmatic, multicentre, open-label, randomised clinical trial.

Background: No high-quality trials have provided evidence of effectiveness and cost-effectiveness of HIV treatment adherence intervention strategies. We therefore examined the effectiveness and cost-effectiveness of the Adherence Improving self-Management Strategy (AIMS) compared with treatment as usual.

Methods: We did a pragmatic, multicentre, open-label, randomised controlled trial in seven HIV clinics at academic and non-academic hospitals in the Netherlands.

Accurate and fast urinalysis in febrile patients by flow cytometry.

Background: The urine culture is worldwide accepted as the gold standard in diagnosing urinary tract infections, but is time consuming and costly, other methods are fast but moderately reliable. We investigated whether counting the number of bacteria by flow cytometry could be a fast and accurate method to analyze urine samples in febrile patients at the emergency department (ED).

Methods: Urine samples were obtained from 140 febrile patients at the ED.

Follow-up of Contacts of Middle East Respiratory Syndrome Coronavirus-Infected Returning Travelers, the Netherlands, 2014.

Notification of 2 imported cases of infection with Middle East respiratory syndrome coronavirus in the Netherlands triggered comprehensive monitoring of contacts. Observed low rates of virus transmission and the psychological effect of contact monitoring indicate that thoughtful assessment of close contacts is prudent and must be guided by clinical and epidemiologic risk factors.

[Unexplained anaemia in men: be aware of hypogonadism].

Unexplained anaemia is not uncommon. We present two male patients suffering from longstanding mild anaemia, for which no cause could be found. We performed an extensive analysis, but there were no signs of malignant disease, chronic inflammation, renal failure, hypothyroidism, myelodysplastic syndrome, haemolysis or nutritional deficiencies.

[Evaluation of diagnosis and therapy of Staphylococcus aureus bacteraemia: recommended minimum treatment duration of 2 weeks not always met].

Objective: Bacteraemia caused by Staphylococcus aureus (SA bacteraemia) can run a relatively mild course, but can also be complicated by focal infections in bones, joints, soft tissue and the heart. The Infectious Disease Society of America (IDSA) advises a transoesophageal echocardiogram (TOE) be taken in each case of SA bacteraemia in order to rule out endocarditis, in addition to sampling blood for culture 2-3 days after the start of treatment. Both the IDSA and the Dutch Stichting Werkgroep Antibiotica Beleid (SWAB - Foundation for Antibiotic Policy Work Groups) recommend that patients with SA bacteraemia be treated intravenously for at least 14 days; longer if a complicated course is expected.

Time-measured phylogenies of gag, pol and env sequence data reveal the direction and time interval of HIV-1 transmission.

Objective: To investigate whether time-measured phylogenetic analysis of longitudinal viral sequences can establish the direction and timing of HIV-1 transmission in an epidemiologically linked transmission cluster of three homosexual men.

Design: An HIV-1-infected homosexual man (patient 1) and his long-term HIV-negative partner (patient 2) engaged in a triangular relationship with an additional partner (patient 3). On the basis of phylogenetic analysis of gag sequences, patient 3 was previously identified as the source for superinfection of patient 1 but the source of HIV-1 infection of patient 2, who seroconverted during the triangular relationship, remained unclear.

Abacavir/lamivudine/zidovudine maintenance after standard induction in antiretroviral therapy-naïve patients: FREE randomized trial interim results.

Maintenance with a triple nucleoside reverse transcriptase Inhibitor (NRTI) regimen after successful induction with a dual NRTI/protease inhibitor (PI) combination may be advantageous, because of low pill burden, favorable lipids, and less drug interactions. This strategy to become free of PI-related problems without losing viral efficacy has not been formally tested. We performed a randomized, open-label, multicenter, 96-week comparative study in antiretroviral therapy (ART)-naïve patients with CD4 View Article and Find Full Text PDF

[Chronic norovirus infection in an immunocompromised patient].

A 68-year-old man, immunocompromised due to non-Hodgkin lymphoma and chemotherapy, was admitted for a community-acquired norovirus infection. He developed chronic intermittent diarrhoea and cachexia. A video-capsule examination showed severe mucosal atrophy in the jejunum.

Recovery of viremic control after superinfection with pathogenic HIV type 1 in a long-term elite controller of HIV type 1 infection.

A human immunodeficiency virus type 1 (HIV-1)-infected elite controller (defined as an untreated HIV-1-infected person with a plasma HIV-1 RNA level <50 copies/mL for at least 12 months) who experienced a viremic episode after superinfection regained natural viremic control, although the viral loads in the patient's 2 partners, infected with the same viral strain, were continuously approximately 30-fold higher. Thus, host mechanisms seem to be able to repeatedly control HIV-1 replication, halting disease progression.

Tumor necrosis factor-alpha genetic predisposing factors can influence clinical severity in nephropathia epidemica.

Severe human infection with Hantavirus is characterized by high fever, cold chills, thrombocytopenia, arterial hypotension, acute renal failure, and/or adult respiratory distress syndrome (ARDS)-like pulmonary involvement, but the clinical course varies greatly between individuals. We investigated whether genetically determined differences in tumor necrosis factor (TNF)-alpha production can influence the severity of Hantavirus disease. We studied a TNF-alpha single-nucleotide promoter polymorphism (SNP) at position -238 (a guanine [G]-to-adenine [A] transition) and ex vivo TNF-alpha production in a recall study of 36 Belgian patients who had a serologically proven form of Puumala virus-induced Hantavirus infection with the kidney as main target organ.

Natural controlled HIV infection: preserved HIV-specific immunity despite undetectable replication competent virus.

Long-term non-progressive HIV infection, characterized by low but detectable viral load and stable CD4 counts in the absence of antiviral therapy, is observed in about 5% of HIV-infected patients. Here we identified four therapy naïve individuals who are strongly seropositive for HIV-1 but who lack evidence of detectable HIV p24 antigen, plasma RNA, and proviral DNA in routine diagnostic testing. With an ultrasensitive PCR, we established that frequencies of pol proviral DNA sequences were as low as 0.
