Dr Boitumelo Pitso has received a Discovery Foundation Sub-Specialist Award to study Paediatric Pulmonology. She hopes to improve the quality of life of children with chronic lung diseases who often battle with coughing, sleeplessness and poor concentration.
With no healthcare role models while growing up in the small Northern Cape town of Kimberley, Dr Boitumelo Pitso was enthralled by the nurses who spilled out of a mobile clinic van that pulled up at her school one day.
“They were doing immunisation and I thought I’d really like to become a caring person like that,” she says. Life was to prove generous with the intervention of a Catholic nun who helped her and other Grade 11 classmates with biology lessons after school. The nun drew out their dreams and ambitions, telling Dr Pitso that she knew people who could show her more about nurses – and doctors. The result was a two-day guided visit to Kimberley Hospital about two hours away by car. “That experience was very influential in shaping my eventual decision to become a doctor,” Dr Pitso says.
She was raised by a single mother who was a teacher at a local school. Despite all the funding challenges for her undergraduate studies, she managed to pull through. Her other childhood memories as a middle child in a six-sibling family involve playing nanny to small children in the neighbourhood and babysitting for her cousin and two older sisters during holidays.
A natural with children
With a mild and patient temperament, she connected particularly well with children who seemed to innately trust her. “So, I decided then and there that I should eventually specialise in paediatrics,” she says.
Dr Pitso was the best student in her final MBChB examinations on Paediatrics and Child Health. Winning a second award for outstanding clinical performance in Internal Medicine was a bonus when she graduated cum laude from Medunsa in 2008. During her community service year, a six-month spell in the Paediatric Department at Kimberly Hospital boosted her passion for paediatrics. She became even more interested in intensive care through a mentor who spent time with her in the paediatric ICU.
In January 2019, Dr Pitso, having qualified as a paediatrician a year earlier, began her Discovery-funded sub-specialist training in Paediatric Pulmonology at the Steve Biko Academic Hospital.
Chronic lung disease prevalence in children
The prevalence of paediatric chronic lung disease in South Africa is currently unknown, but suspicions are that it is alarmingly high and confounded by the burden of infectious diseases such as HIV.
“At least 60% of our follow-up patients have HIV-related bronchiectasis [a condition where the lungs’ airways become damaged], often as a result of delayed diagnosis and late initiation of treatment,” Dr Pitso says.
On average, her unit at Steve Biko Academic Hospital sees about 80 to 100 patients each month from Mpumalanga, Limpopo and Gauteng. Dr Pitso describes patient and caregiver education as the cornerstone of management in paediatric pulmonology. When caregivers are not compliant with this treatment, the recovery process is affected. Failing to explain techniques as well as compliance to treatment makes controlling a condition much harder.
She says that patients with bronchiectasis should know how to do home physiotherapy, which may assist with clearing phlegm from the airway. Dr Pitso feels that the prevention-of-mother-to-child transmission programme has been a great success as well as the antiretroviral rollout programme, but that much more has to be done in rural areas to improve HIV stigma and denialism.
Married to a business development manager with a daughter aged six and son aged three, Dr Pitso lives in Centurion. Asked what her top intervention would be if there were no limits, she responds, “Access to medical care and establishing chronic lung disease centres in all our provinces. Patients die because there’s no follow up and there’s poor communication between the referral centres.”
Research that has also become her calling
Dr Pitso has completed a Discovery-funded MMed dissertation comparing polymerase chain reaction. This is a method widely used in molecular biology to make many copies of a specific DNA segment with conventional culture in detection of respiratory pathogens in subjects with non-cystic fibrosis bronchiectasis. This MMed thesis was accepted for poster presentation at the 2019 European Respiratory Society congress in Spain.
She will spend much of 2019 and 2020 researching the role of airway clearance techniques in improving the quality of life of children with chronic lung disease.
“I’d like to assess the use of a flutter device, with or without physiotherapy, to clear out the lungs of children with chronic lung diseases. Secretions are associated with persistent coughing, which in turn may result in sleeplessness, daytime somnolence, poor concentration and overall poor school performance. Studies so far have focused primarily on cystic fibrosis. I want to broaden the spectrum to other conditions, with the purpose to improve quality of life.”
About the Discovery Foundation
Each year, the Discovery Foundation gives five different awards to outstanding individual and institutional awardees in the public healthcare sector.
The Discovery Foundation is an independent trust with a clear focus to strengthen the healthcare system by making sure that more people have access to specialised healthcare services.
Since 2006, the Discovery Foundation has invested more than R230 million in training and support for more than 400 medical specialists and institutions. The grants support academic research and clinical science, sub-specialist training, rural medicine as well as programmes to develop public healthcare resources. For 2019, Discovery Foundation awarded 42 grants to medical specialists working in South Africa’s healthcare sector to the value of R27 million.
Sometimes a single carefully focussed intervention – like funding the training of an intensivist for an under-staffed, under-equipped intensive care unit at the Nelson Mandela Academic Hospital in Mthatha – can be the catalyst for dynamic change.
Dr Yandiswa Mnyanda, armed with her Discovery Foundation Rural Individual Fellowship Award, is determined to make a difference in her community by finding out why survivors of sexual violence in the Eastern Cape report so late for care.
With his Discovery Foundation Rural Individual Fellowship Award, Dr Andrew Oyemwimina investigated the prevalence of HIV infection among paediatric patients who were admitted to hospital in 2016 – the first study of its kind in the Eastern Cape.
