Dr Bonita van der Westhuizen, Senior lecturer and Pathologist in the UFS Department of Medical Microbiology, identified the first case of S. oblongispora mucormycosis in sub-Saharan Africa and among HIV-positive patients.

Medical staff at the University of the Free State (UFS) and the National Health Laboratory Service (NHLS) at the Universitas Academic Hospital have identified the first case of S. oblongispora mucormycosis in sub-Saharan Africa and among HIV-positive patients.

This discovery was made when a 32-year-old male patient was admitted to the Universitas Academic Hospital with right-sided facial swelling. The patient was HIV-positive, with a CD4 count of 50 cells/µl, and on antiretroviral therapy (ART), together with trimethoprim–sulfamethoxazole (TMX) prophylaxis. Additionally, he had hypertension for which he was also receiving treatment. The patient’s facial swelling rapidly progressed, with extension of redness and swelling observed daily.

Four days after admission, he underwent computerised tomography (CT) scan, and tissue biopsies were collected. The patient died three days later.

 

A significant discovery

Dr Bonita van der Westhuizen, Senior lecturer and Pathologist in the UFS Department of Medical Microbiology, who identified this rare fungus said this discovery is significant because it highlights the presence of this fungal pathogen in a region where it may have been previously unrecognised or underreported. It now raises awareness about the diversity of fungal infections affecting immunocompromised populations and underscores the need for improved diagnostics, surveillance, and treatment strategies in the region.

Dr Van der Westhuizen says though it is unclear where the deceased might have picked up this infection, moulds are ubiquitous in the environment. Patients usually get infected by inhalation of spores or traumatic implantation.

Together with colleagues Drs Liska Budding and Christie Esterhuysen, both from the UFS Department of Anatomical Pathology and the NHLS, and Prof Samantha Potgieter, Infectious disease expert in the UFS Department of Internal Medicine, Dr Van der Westhuizen published the case earlier this month (August) in the Journal Case Reports in Pathology.

 

Progresses rapidly

“Mucormycosis, which is caused by fungi in the order Mucorales, progresses rapidly due to a combination of factors related to the fungus, the host, and external influences. Mucorales fungi are known for their fast growth and ability to invade blood vessels. This allows the infection to spread quickly through the body, potentially reaching vital organs,” she says.

These fungi, Dr Van der Westhuizen explains, can resist being killed by immune cells, allowing them to establish infection. Some Mucorales fungi can produce toxins that disrupt blood vessels, further aiding the spread of the infection. Additionally, certain host conditions weaken the body's defences, allowing the infection to spread quickly.

“External factors that may play a role are traumatic injuries, endothelial damage and rarely hospital acquired infections. In essence, the aggressive nature of Mucorales fungi combined with weakened host defences and external factors creates a perfect storm for rapid disease progression in susceptible individuals.

“The Mucorales as a group normally infects patients with underlying risk factors including factors including diabetes mellitus, malignancies, transplant recipients, and current or past COVID-19 infection, however, this organism in particular, usually infects immunocompetent patients after traumatic inoculation,” says Dr Van der Westhuizen.

It is important to note, she continues, that all available data comes from research done in tropical regions. There is no data on this organism in sub-Saharan Africa which means it is still unknown what role this pathogen plays in our local patient population. The diagnostic complexities and rapid disease progression may contribute to the paucity of data in developing countries.

This infection can be treated with available antifungal agents, as well as surgical debridement of infected tissue. The challenge, however, is the rapid disease onset and progression to death. There is only a tiny window to help the patient. That is why clinical suspicion is so important, as immediate aggressive surgical debridement with antifungal agents is the only way to improve patient outcome. Unfortunately, this infection still has a high mortality rate, despite therapy.

 

Fungal diagnostics is complex

An invasive fungal infection (IFI) was not suspected in this patient, and he received neither antifungal therapy nor surgical interventions. His cause of death, likely the IFI, was only identified after he passed away and because of a combination of different testing platforms was used to identify this infection. Says Dr Van der Westhuizen: “This is unfortunately the case with mould infections as most readily available diagnostic methods lack sensitivity and these pathogens take long to grow in the laboratory. Fungal diagnostics is a specialised field that requires expertise. However, if clinicians are aware of these infections and they have an increased index of suspicion, appropriate therapy can be initiated even before the results are available.

“If clinicians suspect this type of infection early and they involve the infectious diseases physicians, microbiology and histopathology for support and advice, they will be guided to collect the most appropriate samples to ensure that an accurate diagnosis is made.”

There is a possibility that these infections had been missed before and even still today. Fungal diagnostics is a very complex field for various reasons. There is no highly sensitive stand-alone test to make a rapid diagnosis available. As newer methods are being developed and molecular diagnostics are advancing, fungal diagnostics are improving. A combination of testing platforms is still required to improve the sensitivity of diagnosing these infections.

Her hope for this research, says Dr Van der Westhuizen, who will now also embark further research into local fungal species for her PhD, their epidemiology, diagnostics, and their impact on vulnerable populations, ultimately contributing to better clinical care and health outcomes, is to advance understanding and awareness of Invasive mould infections specifically S. oblongispora, in sub-Saharan Africa and among HIV patients. She aims to improve early diagnosis, treatment strategies, and clinical outcomes, as well as to highlight the importance of monitoring fungal infections in immunocompromised populations. Additionally, her goal includes encouraging further research and collaboration in this area to better address fungal infections in the region.

True leadership may mean admitting disunity
 

In this edited extract from the inaugural King Moshoeshoe Memorial Lecture at the University of the Free State, Professor Njabulo S Ndebele explores the leadership challenges facing South Africa

RECENT events have created a sense that we are undergoing a serious crisis of leadership in our new democracy. An increasing number of highly intelligent, sensitive and committed South Africans, across class, racial and cultural spectrums, confess to feeling uncertain and vulnerable as never before since 1994.

When indomitable optimists confess to having a sense of things unhinging, the misery of anxiety spreads. We have the sense that events are spiralling out of control and that no one among the leadership of the country seems to have a definitive handle on things.

There can be nothing more debilitating than a generalised and undefined sense of anxiety in the body politic. It breeds conspiracies and fear.

There is an impression that a very complex society has developed, in the last few years, a rather simple, centralised governance mechanism in the hope that delivery can be better and more quickly driven. The complexity of governance then gets located within a single structure of authority rather than in the devolved structures envisaged in the Constitution, which should interact with one another continuously, and in response to their specific settings, to achieve defined goals. Collapse in a single structure of authority, because there is no robust backup, can be catastrophic.

The autonomy of devolved structures presents itself as an impediment only when visionary cohesion collapses. Where such cohesion is strong, the impediment is only illusory, particularly when it encourages healthy competition, for example, among the provinces, or where a province develops a character that is not necessarily autonomous politically but rather distinctive and a special source of regional pride. Such competition brings vibrancy to the country. It does not necessarily challenge the centre.

Devolved autonomy is vital in the interests of sustainable governance. The failure of various structures to actualise their constitutionally defined roles should not be attributed to the failure of the prescribed governance mechanism. It is too early to say that what we have has not worked. The only viable corrective will be in our ability to be robust in identifying the problems and dealing with them concertedly.

We have never had social cohesion in South Africa — certainly not since the Natives’ Land Act of 1913. What we definitely have had over the decades is a mobilising vision. Could it be that the mobilising vision, mistaken for social cohesion, is cracking under the weight of the reality and extent of social reconstruction, and that the legitimate framework for debating these problems is collapsing? If that is so, are we witnessing a cumulative failure of leadership?

I am making a descriptive rather than an evaluative inquiry. I do not believe that there is any single entity to be blamed. It is simply that we may be a country in search of another line of approach. What will it be?

I would like to suggest two avenues of approach — an inclusive model and a counter-intuitive model of leadership.

In an inclusive approach, leadership is exercised not only by those who have been put in some position of power to steer an organisation or institution. Leadership is what all of us do when we express, sincerely, our deepest feelings and thoughts; when we do our work, whatever it is, with passion and integrity.

Counter-intuitive leadership lies in the ability of leaders to read a problematic situation, assess probable outcomes and then recognise that those outcomes will only compound the problem. Genuine leadership, in this sense, requires going against probability in seeking unexpected outcomes. That’s what happened when we avoided a civil war and ended up with an “unexpected” democracy.

Right now, we may very well hear desperate calls for unity, when the counter-intuitive imperative would be to acknowledge disunity. A declaration of unity where it manifestly does not appear to exist will fail to reassure.

Many within the “broad alliance” might have the view that the mobilising vision of old may have transformed into a strategy of executive steering with a disposition towards an expectation of compliance. No matter how compelling the reasons for that tendency, it may be seen as part of a cumulative process in which popular notions of democratic governance are apparently undermined and devalued; and where public uncertainty in the midst of seeming crisis induces fear which could freeze public thinking at a time when more voices ought to be heard.

Could it be that part of the problem is that we are unable to deal with the notion of opposition? We are horrified that any of us could be seen to have become “the opposition”. The word has been demonised. In reality, it is time we began to anticipate the arrival of a moment when there is no longer a single, overwhelmingly dominant political force as is currently the case. Such is the course of history. The measure of the maturity of the current political environment will be in how it can create conditions that anticipate that moment rather than seek to prevent it. We see here once more the essential creativity of the counter-intuitive imperative.

This is the formidable challenge of a popular post-apartheid political movement. Can it conceptually anticipate a future when it is no longer overwhelmingly in control, in the form in which it is currently, and resist, counter-intuitively, the temptation to prevent such an eventuality? Successfully resisting such an option would enable its current vision and its ultimate legacy to our country to manifest in different articulations, which then contend for social influence. In this way, the vision never really dies; it simply evolves into higher, more complex forms of itself. Consider the metaphor of flying ants replicating the ant community by establishing new ones.

We may certainly experience the meaning of comradeship differently, where we will now have “comrades on the other side”.

Any political movement that imagines itself as a perpetual entity should look at the compelling evidence of history. Few movements have survived those defining moments when they should have been more elastic, and that because they were not, did not live to see the next day.

I believe we may have reached a moment not fundamentally different from the sobering, yet uplifting and vision-making, nation-building realities that led to Kempton Park in the early ’90s. The difference between then and now is that the black majority is not facing white compatriots across the negotiating table. Rather, it is facing itself: perhaps really for the first time since 1994. Could we apply to ourselves the same degree of inventiveness and rigorous negotiation we displayed leading up to the adoption or our Constitution?

This is not a time for repeating old platitudes. It is the time, once more, for vision.

In the total scheme of things, the outcome could be as disastrous as it could be formative and uplifting, setting in place the conditions for a true renaissance that could be sustained for generations to come.
