🎉to Charlotte Rabault - she published this after a 6-month fellowship in Joburg

In patients aged >90 days, prior antifungal use was associated with non-susceptible Candida bloodstream infection (OR 2.02). In young infants, hospital transmission was more influential.

Genomic epidemiology of Histoplasma in Africa

Rutendo Mapingo ... @neleshg.bsky.social Daniel Matute

Three genetically distinct lineages identified among African Histoplasma isolates

journals.asm.org/doi/10.1128/...
Phylogenetic tree and Principle Component Analysis of African histoplasma isolates Morphological characteristics of the Histoplasma Africa samples. We show the morphology of isolate SA1704, but all other isolates show similar characteristics. (A) Morphology of a 3-week-old Africa isolate growing on a plate of Sabouraud dextrose agar at 25°C. (B) Light microscope slide stained with lactophenol blue showing the mycelial stage of Histoplasma Africa. (C) A similarly prepared slide for T-3-1 which belongs to H. ohiense. (D) Culture of a 2-week-old Africa growing on brain heart infusion agar at 35°C. (E) Slide of electron microscopy image of a 2-week-old Africa (SA0297) growing on Sabouraud dextrose agar at 25°C showing the microconidia of mold form (magnification = ×2,000, extra high tension = 5.00 kV, working distance = 9.2 mm, Signal A = SE2, bar 10 µm). (F) Electron microscopy image of a 2-week-old Hcf (SA20VMK) growing on Sabouraud dextrose agar at 25°C showing a tuberculate macroconidium (magnification = x2,000, EHT = 5.00 kV, WD = 9.2 mm, Signal A = SE2, bar 10 µm).

Results from our CAST-NET cohort study published. Excellent national coverage of cryptococcal antigen screening in SA but real challenges to act on CrAg+ results to exclude meningitis and dispense pre-emptive antifungals

Jayne Ellis presenting data from our cohort with CD4 <100 undergoing CrAg screening in SA at #IAS2025 (poster 2803)

59% (86/146) had CMV viraemia - strongly & independently associated with ⬆️mortality, more than quadrupling odds of death at 6-months (adjusted OR 4.02, 95%CI 1.27-12.7)
Cumulative 6-month mortality amongst 146 adults with advanced HIV disease, stratified by baseline CMV viraemia status

During 2016–2023, among 21,195 US patients who tested positive for Candida auris skin colonisation, 6.9% were subsequently found to have a positive clinical specimen, 2.8% from blood

Probably an underestimate but useful to know

We brought together teams from 13 neonatal sepsis surveillance studies, conducted across 35 sites in South Asia and Africa, to pool data and estimate prevalence of capsule and O types amongst #Klebsiella pneumoniae causing sepsis in newborns, using Bayesian modelling.

Great updates and learning at the histoplasmosis working group meeting at the tail end of ISHAM triennial conference

And new targets will be set...

"Considering this conflicting evidence, there is equipoise to support a clinical trial in which persons with AHD without overt symptoms suggestive of histoplasmosis and with Histoplasma antigenuria are randomized to pre-emptive antifungal therapy or to observation."

Histoplasmosis remains an important cause of AIDS-related deaths in many regions

Histoplasma antigen tests are now cheap, accessible, and can be done at POC

Are such assays ready to be used for routine screening of patients with advanced HIV?

We have thoughts 🤔

Her clinical team was reluctant to talk to us about the futility of curative treatment or end-of-life care. They wanted to continue as though she would walk out of hospital.

This didn't make sense. We wanted her to be comfortable, and not to end her life in a busy noisy bright surgical ICU.

In 2008, my wonderful 84-year-old grandmother died in hospital with perforated diverticulitis. I was a newly-qualified clinical microbiologist then. When it became clear that she wouldn't recover, I asked for her to be transferred out of ICU, to receive palliative care and to stop antibiotics...

Cryptococcal Meningitis Treatment Beyond HIV: Recognizing the need for Individualized Immune-Based Strategies

Hyunah Yoon, Liise-anne Pirofsky, @drboulware.bsky.social

In non-HIV-associated CM, ⬇️ing immunosuppression --> ⬆️ inflammation --> 🧠 damage.

academic.oup.com/cid/advance-... #TxID #IDSky
A line graph illustrating immunosuppressive drug intensity and immune cell recovery (CD4+ T, B and NK cells) over months following kidney transplantation, highlighting a window of heightened cryptococcal disease risk. Two parabola diagrams comparing HIV-associated cryptococcal damage and non-HIV transplant-associated damage. In both settings, too little or too much immune response can result in host damage (left and right arms of the parabola). However, in non-HIV transplant patients, the overall position on the parabola is less predictable, due to the heterogeneous effects of immunosuppressive medications before and during cryptococcal infection.

Fungi can protect the environment, grow food and even develop new medicines. 🍄

But they can also cause disease.

As climate change spreads pathogenic fungi to new places, more people worldwide will be at risk.
