Always reactivation.

Evidence for:

Reactivation of Epstein-Barr Virus (EBV)
Reactivation of latent Tuberculosis (LTBI)
Reactivation of dormant cancer cells.

The downstream negative population health effects of unmitigated SARS-CoV-2 transmission are undeniable now.
We've known that Covid increases the risk in survivors of cancer, but today @nature.com a mechanism of reactivation of cancer cells elucidated in the experimental model

Very obvious now that SARS-CoV-2 infection can be characterised as: AAA

A: Acceleration (e.g. dementia, vascular)
A: reActivation (e.g. EBV, LTBI)
A: Aging (inflammation, telomere shortening)

Longevity and / or healthspan cannot be fully addressed without understanding this.
Covid accelerates vascular aging
An 18-country, 38-center study of ~2,000 participants
—Effect predominantly in women, adding 5 years of aging
—Seen with non-hospitalized and mild-moderate Covid
—Reversible in some at 1-year; vaccination link to protection

Algo me dice que es bastante más del 65% en el colectivo LTBI+ y bastante menos en el G.

New paper out with 💫 internal medicine resident (now staff) John Kim evaluating outcomes of military members at our base with positive LTBI screens between 1/22-6/24

We found:
6,321 QFT-Plus assays
192 (3%)➕
97 (51%) LTBI
58 (60%) initiated 💊
41 (71%) completed 💊

remember, during Ramadan, you can recommend that patients take their medications at night when the fasting period is over — otherwise, consider deferring nonurgent treatments (HCV, HBV, LTBI) to after

Polio, HIV, Measles, Viral Hepatitis, Tuberculosis/LTBI, STIs, it'll all balloon without the essential work of the WHO.

Vax hesitancy will likely explode even moreso and in concert with other US health policies, child mortality will likely be worse everywhere.

Because of that, the U.S. does not routinely use BCG, even during outbreaks. After a TB exposure, the focus is testing and treatment of latent TB infection (LTBI), not vaccination.

- El 30,6% de las personas LGTBI+ vive en riesgo de pobreza, un 13% más que la media.
- Las mujeres LTBI+ tienen una tasa de paro del 17,39%, mucho más alta que la de la población en general.
- 4 de cada 10 mayores LGBTI+ están en desempleo felgtbi.org/wp-content/u... @felgtbi.bsky.social

For this reason IGRAs including Quantiferon gold are not recommended to monitor response to LTBI therapy.
Guidelines are very clear on this. I do not repeat IGRA to assess treatment efficacy and clinical decision-making should not hinge on post-treatment IGRA results.

have you explored RBT > RIF?

but to answer your q, yes, we do LTBI rx with FQ for intolerance of RIF and INH! we base this on the MDR contact data

Don't do this.
Not sensitive enough for ne IGRA to rule out active TB.
Not specific for active disease as possible in LTBI (and previous disease).
Rarely MIGHT be helpful in swinging balance of probabilities in difficult cases where microbiology/ molecular testing not possible.

I was curious what the historical latent TB prevalence rate was in US.

4-5%, (highest in middle-aged ppl and elderly), as of 2016 & declining very slowly.

200 in a single school is extremely high. Yikes. Today is a GREAT day to clean the air.

In some individuals, the T-cell response wanes enough to fall below the assay threshold but that immune memory is heterogeneous and durable in many people, so results vary. Across studies some patients revert to negative after LTBI treatment but many remain persistently positive.
