Dr Aviwe Ntsethe’s curiosity in the Medical field deepened when he started exploring the complexities of human physiology and the crucial role of the immune system in cancer, leading to him graduating with a PhD.

Growing up in the small town of Bizana in the Eastern Cape, Ntsethe attended Ntabezulu High School, where his passion for Medical Science took root. Despite facing significant challenges, including limited funding opportunities for his studies, he remained determined to advance in the discipline.

Throughout his PhD journey at UKZN, Ntsethe had to juggle multiple jobs to support himself and his studies while conducting his research. He worked at Netcare Education and the KwaZulu-Natal College of Emergency Care, and later took up a position as a contractual laboratory technician in the Department of Physiology at UKZN. It was with the guidance of his PhD supervisor, Professor Bongani Nkambule, that he learned critical work ethics and advanced laboratory techniques. The co-supervision of Professor Phiwayinkosi Dludla further enriched his research experience and contributed to his academic growth.

Ntsethe’s thesis focused on investigating B cell function and immune checkpoint expression in patients with Chronic Lymphocytic Leukaemia (CLL). The study found that patients with CLL had higher levels of immune checkpoint proteins in their B cell subsets, which play a crucial role in regulating the immune system.

Furthermore, using monoclonal antibodies that target these immune checkpoints, he found these patients could potentially benefit from immunotherapy. Specifically, immunotherapy may improve the function of B cells, key players in fighting infections and cancers, thereby offering new hope for better outcomes in patients with CLL.

He has published three papers from this study. ‘I am excited and proud when I reflect on my achievement of completing this significant journey which was both challenging and rewarding, pushing me to expand my knowledge and skills in ways I never imagined.’

Now, a lecturer at Nelson Mandela University, Ntsethe is committed to mentoring the next generation of Medical scientists. He continues to use the invaluable knowledge and experience he gained during his PhD studies to inspire students and cultivate their passions in research and health sciences. Looking ahead, Ntsethe hopes to expand his research, focusing on immune system interactions in chronic diseases while also encouraging students from diverse backgrounds to pursue careers in Medical Science.

Outside academia, Ntsethe enjoys travelling, staying physically active through workouts, playing chess and indulging in coding or programming.

Monday, 27 May 2024. The passing of esteemed cardiologist Dr Surendra Singh (11 April 1955 – 16 May 2024) at the age of 69 after a short illness is a tremendous loss to healthcare in KwaZulu-Natal, the communities he served and everyone who knew him.

“We wish to express our sincere condolences to Dr Singh’s wife, Professor Shanta, and his children Rajiv, Ameet and Rhea,” said Netcare uMhlanga Hospital general manager Wendy Beato.

“We mourn the passing of an exceptional healthcare professional and a man of stature. Dr Singh was highly respected and much loved by his colleagues, patients and the staff and management of Netcare uMhlanga Hospital, where he has practised for several years.

“Dr Singh will be deeply missed by all who had the privilege to know him,” she says.

After qualifying as a cardiologist in 1990, Dr Singh embarked on a journey during which he harnessed the power of his knowledge to heal others. Known for this brilliance both as a man and a doctor, he possessed a rare combination of exceptional expertise, humility and deep caring.

“Dr Singh’s dedication to his patients was evident throughout his career, and he continued to provide much valued service at Netcare uMhlanga Hospital until he became ill. His passing leaves a deep void for all who knew him and the countless patients whose lives he touched throughout his career.

“Dr Singh’s legacy as a caring healthcare provider and respected cardiologist will endure. Through his considerable dedication and expertise, he improved and saved lives while inspiring a new generation of healthcare professionals. His passion for healing and deep commitment to his patients will be forever remembered. Although his time with us was cut short, the impact of his life’s work will continue to be felt for many years to come,” Beato concluded.

Unemployed Doctors March to Department of Health

Over 80 unemployed doctors marched from UNISA campus on Longmarket Road to the KwaZulu-Natal Department of Health’s offices in Langalibele Street, Pietermaritzburg, on Monday.

They went to hand over their CVs and a memorandum demanding that the healthcare budget be increased to accommodate over 700 qualifying medical practitioners. The department was given 14 days to respond.

Eighty-four unemployed doctors also signed a register handed to the department.

The doctors were met by Deputy Health Minister Sibongiseni Dhlomo who said health minister Joe Phaahla had another engagement. Dhlomo said the department was working to address the issue of unemployed doctors, and that the minister would raise it this week in Parliament and ask that healthcare be exempt from budget cuts.

Dr Siya Shozi, part of a “small committee” of unemployed doctors with no political affiliation mandated to liaise with the department, said the march was coordinated through a WhatsApp group. Shozi was happy with the turnout but said it did not represent the large number of unemployed doctors in KZN and its rural areas.

Busiziwe Mancotywa, a grade one medical officer who has been unemployed since completing her training at the end of last year, said, “You apply for some positions where you meet the minimum requirements but for whatever reason you are never contacted”.

Mancotywa was joined by her brother, Nqaba, who is finishing his internship at Greys Hospital. He said if action is not taken now, he won’t find a job in the future.

Nomfundo Mbanjwa, also a grade one medical officer, complained about the cost of applying for jobs, including printing applications and transport to interviews. Mbanjwa says she had to sell her car to cover these costs.

Representatives from the South African Medical Association Trade Union (SAMATU) and the Public Servants Association of South Africa (PSA) joined the march and pledged support for the doctors.

NICD Issues Lassa Fever Alert over KZN Case

On By ModernMedia

The National Institute for Communicable diseases has reported that a case of Lassa fever was diagnosed in a man from KwaZulu-Natal on 12 May 2022. The man had extensive travel history in Nigeria before returning to South Africa. He fell ill after entering South Africa and was hospitalised in a Pietermaritzburg hospital. The diagnosis of Lassa fever was confirmed by lab tests. Sadly, the man succumbed to the infection.

Contact tracing and monitoring is underway. No secondary cases of Lassa fever have been confirmed at the time of this report. In February 2022, three cases of Lassa fever had been reported in the UK, with the first travelling from Mali and the other two resulting from secondary transmission.

Originally discovered in 1969, Lassa fever is a rodentborne viral haemorrhagic fever endemic to West African countries and is caused by Lassa virus. Up to 300 000 cases of Lassa fever, with about 5000 deaths, are recorded annually in the endemic countries. Currently there is no vaccine for Lassa fever. The clinical course of Lassa fever is either not recognised or mild in 80% of patients; however, about 20% of patients might experience severe disease, including facial swelling, hepatic and renal abnormalities, pulmonary oedema, and haemorrhage. Although overall case-fatality rates for patients with Lassa fever is about 1%, rates among hospitalised case-patients are >15%. Intravenous administration of the antiviral drug ribavirin has become the standard of care for treatment of Lassa fever, but data on the efficacy of intravenous ribavirin are limited. The original study among Lassa fever patients in Sierra Leone found survival to be significantly higher (p = 0.0002) among those who obtained ribavirin within the first 6 days of illness (55%) compared with those who never received the drug (5%). 

The natural reservoir of this virus in endemic countries is the Mastomys rat. The rats are persistently infected, shedding the virus in their urine and faeces. Humans can come into contact with the virus through direct contact or inhalation of the virus in areas that are infested with the infected rats. For example, contact with contaminated materials, ingestion of contaminated food or inhalation of air that has been contaminated with urine droplets. Person-to-person transmission of the virus does not occur readily and the virus is not spread through casual contact.

Person-to-person transmission is not common and is mostly associated with the hospital-setting where healthcare workers have contact with the infected blood and bodily fluids of a patient. Cases of Lassa fever in travellers returning from endemic countries are reported from time-to-time. In 2007 a case of Lassa fever was diagnosed in South Africa. That case involved a Nigerian citizen with extensive travel history in rural parts of Nigeria before falling ill, and he received medical treatment in South Africa. There were no reported secondary cases of Lassa fever on this occasion. Recently, in February 2022, an imported case of Lassa fever with secondary cases were identified in the United Kingdom.

Dozens of Healthcare Facilities Damaged in KZN Floods

The floods which have inundated KwaZulu-Natal this week and prompted the declaration of a national state of disaster, have damaged at least 58 healthcare facilities. So far, the floods have claimed the lives of 443 people, with 63 still missing.

Damage has been sustained to the roofs, floors and fencing of healthcare facilties, the KwaZulu-Natal health department said. Water shortages from infrastructure damage had forced some hospitals to divert patients elsewhere. Environmental health practitioners are monitoring clinical data for early identification of any waterborne diseases.

Health MEC Nomagugu Simelane said there had been an influx of patients due to the torrential rains.

“We can confirm that our hospitals and clinics have been seeing a higher number of trauma and emergency patients than usual, particularly in the densely populated districts,” she said.

Simelane thanked the courage and dedication of the province’s healthcare workers, noting that many had simply put in extra hours to compensate. Damage to infrastructure such as roads meant that some healthcare workers have had to sleep at the facilities, she noted. Other facilities will try and provide accommodation for them.

To cope with the strain on morgues, KZN Premier Sihle Zikalala said: “We have mobilised additional resources, including seven doctors, to ensure that post mortems are completed speedily, in order to avoid congestion and to enable those who are grieving to bury their loved ones. Our officials are constantly monitoring the situation and sending bodies to those facilities that do have space.”

“All the resources allocated for flood relief and the recovery and rebuilding process will be utilised in line with fiscal rectitude, accountability, transparency and openness. We want to emphasise the fact that, having learnt lessons of Covid-19, no amount of corruption, maladministration and fraud will be tolerated or associated with this province,” Premier Zikalala said.

Wastewater Analysis Shows KZN in Third Wave

On By ModernMedia

Viral load analysis of wastewater suggests that KwaZulu-Natal may already have entered the third wave of COVID infections, according to research by DUT.

The Institute for Water and Wastewater Technology, based at DUT, has been monitoring viral loads of wastewater at the central treatment plant in eThekwini since July 2020, and found a clear correlation between clinical cases and viral loads detected in wastewater.

While clinical cases were reported to be on the increase in KZN since April 20 this year, they had found an increase in wastewater viral load some three weeks earlier.

The Institute for Water and Wastewater noted that the peak of the COVID second wave in South Africa occurred in January with an average of 40 000 cases in KwaZulu-Natal.

Over this period, the researchers measured average viral loads of 4.72 log copies per 100 millilitres at the central wastewater treatment plant. However, over the last four weeks, viral loads have averaged 5.57 log copies per 100 millilitres.

This has led the institute to suggest that there are far more cases than have been reported clinically, with a significant presence of asymptomatic individuals.

A report [PDF] on the third wave by the National Institute for Communicable Diseases indicated that there was a seroprevalence for SARS-CoV-2, a proxy for previous infection, of 30% to 40% after the third wave. This indicates that COVID infections were already widespread, and lends credence to the institute’s notion of extremely widespread asymptomatic cases. Projections for KZN showed a much lower peak for hospital admissions.
