Abstract

We compared paired plasma and dried blood spot (DBS) samples from 54 HIV-1-treated children living in Bangui, Central African Republic, for antiretroviral-resistance-associated mutations. All children displayed virological failure (HIV-1 RNA >3.70 log10copies/ml). Testing for resistance genotype was carried out in a reference laboratory in Paris, France. A successful test result was obtained in 54 (100%) plasmas and 25 DBSs (46%). Among the 732 resistance-associated mutations analyzed, 718 were identical, leading to a high concordance rate of 98.1%. Genotypic resistance tests on DBS samples were found to be highly feasible and accurate in a foreign reference laboratory, but with additional costs for shipping and decreased sensitivity.

Ob bei einer Notfalloperation nach Schenkelhalsfraktur eine Hemiarthroplastik oder eine totale Endoprothese (TEP) eingebaut wird, sollte nicht allein vom Alter der Patientinnen und Patienten abhängen. Auch über 90-Jährige können von der TEP profitieren.

Niedriger diastolischer Blutdruck erhöht Risiko für schwere kardiovaskuläre Komplikationen

25.04.2024 Hypotonie Nachrichten

Wenn unter einer medikamentösen Hochdrucktherapie der diastolische Blutdruck in den Keller geht, steigt das Risiko für schwere kardiovaskuläre Ereignisse: Darauf deutet eine Sekundäranalyse der SPRINT-Studie hin.

Bei schweren Reaktionen auf Insektenstiche empfiehlt sich eine spezifische Immuntherapie

Insektenstiche sind bei Erwachsenen die häufigsten Auslöser einer Anaphylaxie. Einen wirksamen Schutz vor schweren anaphylaktischen Reaktionen bietet die allergenspezifische Immuntherapie. Jedoch kommt sie noch viel zu selten zum Einsatz.

Therapiestart mit Blutdrucksenkern erhöht Frakturrisiko

25.04.2024 Hypertonie Nachrichten

Beginnen ältere Männer im Pflegeheim eine Antihypertensiva-Therapie, dann ist die Frakturrate in den folgenden 30 Tagen mehr als verdoppelt. Besonders häufig stürzen Demenzkranke und Männer, die erstmals Blutdrucksenker nehmen. Dafür spricht eine Analyse unter US-Veteranen.
