Hepatotoxicity during TB treatment in people with HIV/AIDS related to NAT2 polymorphisms in Pernambuco, Northeast Brazil.

Hepatotoxicity during TB treatment in people with HIV/AIDS related to NAT2 polymorphisms in Pernambuco, Northeast Brazil. Ann Hepatol. 2019 Oct 24;: Authors: Araujo-Mariz C, Militão de Albuquerque MFP, Lopes EP, Ximenes RAA, Lacerda HR, Miranda-Filho DB, Lustosa-Martins BB, Pastor AFP, Acioli-Santos B Abstract INTRODUCTION AND OBJECTIVE: Hepatotoxicity during tuberculosis (TB) treatment is frequent and may be related to the Arylamine N-Acetyltransferase (NAT2) acetylator profile, in which allele frequencies differ according to the population. The aim of this study was to investigate functional polymorphisms in NAT2 associated with the development of hepatotoxicity after initiating treatment for TB in people living with HIV/AIDS (PLWHA) in Pernambuco, Northeast Brazil. MATERIAL AND METHODS: This was a prospective cohort study that investigated seven single nucleotide polymorphisms located in the NAT2 coding region in 173 PLWHA undergoing TB treatment. Hepatotoxicity was defined as elevated aminotransferase levels and identified as being three times higher than it was before initiating TB treatment, with associated symptoms of hepatitis. A further 80 healthy subjects, without HIV infection or TB were used as a control group. All individuals were genotyped by direct sequencing. RESULTS: The NAT2*13A and NAT2*6B variant alleles were significantly associated with the development of hepatotoxicity during TB treatment in PLWHA (p

Conclusions: The efficacies of daily TDF and event-driven TDF use were not significantly different in preventing new infections among HIV-negative MSM. Event-driven TDF use is economical and effective and is worth popularizing. Our results provide evidence for the application and promotion of the PrEP strategy in the MSM population in China.

This study investigated the interaction of synthesized immunogenic ‘a’ determinant (aD) region of hepatitis B virus surface antigen (HBsAg) with PAMAM G4 and anti-HBsAg antibody, as a potential bio-nanogate for anti-HBsAg detection. The aD peptide fused with maltose binding protein (MBP), was confirmed with Western blotting. Nano-Differential Scanning Fluorimetry (nano-DSF) study revealed that the interaction of MBP-aD with anti-HBsAg indicated a higher thermal stability as compared to its interaction with PAMAM G4. Electrochemical impedance spectroscopy showed that a higher binding constant of MBP-aD interacti...

AbstractThis paper presents a probable case of subligamentous tuberculous spondylitis (STBS), a rare form of extra ‐pulmonary tuberculosis, diagnosed in the skeleton of a middle‐aged male discovered in the ossuary of the Franciscan crypt of the St. Anthony and St. Eusebius church, which lies in north‐western Italy. The skeleton can be dated back between the 17th‐19th centuries. This rare type of tubercul osis was identified in the thoracic and lumbar spine, with no further evidences at the level of the cranial and other postcranial bones. The concomitance of osteoclastic and osteoblastic activities, scalloping, rea...

Authors: Lionetti V, Barile L Abstract Over the last 20 years increasing number of patients with multimorbidity and polypharmacy underwent different types of elective non-cardiac and cardiac surgery. Despite surgery is safer today than in the past, rate of perioperative major adverse cardiovascular events is still attracting significant attention from both clinicians and researchers. The perioperative myocardial infarction (PMI), a permanent damage of the heart, is a major cause of short and long term morbidity and mortality in current surgical populations. Although it is primarily the result of local myocardial is...

Conclusion The vaccination comprises a misguided and unsafe national health care program which claims to prevent disease. Many significant health injuries are associated with vaccinating adults. Government resources are being spent researching and developing new and different vaccinations. Subjecting adults to more vaccinations is likely to cause more health injury and illness.

Chawla Viral hepatitis is a cause for major health care burden in India and is now equated as a threat comparable to the “big three” communicable diseases – HIV/AIDS, malaria and tuberculosis. Hepatitis A virus and Hepatitis E virus are predominantly enterically transmitted pathogens and are responsible to cause both sporadic infections and epidemics of acute viral hepatitis. Hepatitis B virus and Hepatitis C virus are predominantly spread via parenteral route and are notorious...

The 2030 Agenda for Sustainable Development has recognised an infectious disease that the Millennium Development Goals omitted. UN Member States have now made a commitment to combat hepatitis under Goal 3.3 of the Sustainable Development Goals (SDGs),1 as a threat comparable to the “big three” communicable diseases—HIV/AIDS, tuberculosis, and malaria. Viral hepatitis is not an emerging infectious disease, but the cause of a silent epidemic of serious and often fatal liver disease, including liver cancer; the causative agents (hepatitis A, B, C, D, and E viruses) have been circulating in the human population for millennia.
