As Nigerian hospital deploys maggots’ healing power

As the country grapples with the second surge of the Covid-19 pandemic and Lassa fever, the Aminu Kano Teaching Hospital (AKTH), has pioneered the use of clinical graded maggots to treat chronic wounds that often lead to the amputation of limbs. The procedure is called Maggot  Debridement Therapy (MDT). It is an ancient process that has been rediscovered by Medical Entomologist for the benefit of humanity.  And it is now heart-warmingly  available in Nigeria. The maggots are applied to the wounds  that develop mostly  in patients that have underlying ailments, such as diabetes and vascular diseases. According to WebMD, “The maggots clean the wounds by consuming  all the dead and infected tissues, without hurting healthy tissues. They also help fight infection and speed healing by releasing chemicals that kill bacteria.” The use of specially breeded  selected species of  larvae in laboratory to treat stubborn sores at the Aminu Kano Teaching Hospital, which pioneered it in Nigeria, is  by Dr. Mustapha Ahmed Yusuf, a Medical Entomologist who completed a PhD program in 2020.

Dr Mustaph noted that  the Aminu Kano Teaching Hospital in Kano is the model  and pacesetter for maggot therapy in Nigeria  because, so far, it is the only tertiary health institution in the country that has a Maggot Debridement Therapy Centre. He added that,  “Medical entomologists work in collaboration with orthopaedic and  plastic surgeons in the hospital. The orthopaedic surgeons refer patients for maggot therapy as the final treatment option before amputation; and  plastic surgeons  conduct skin graft when the wound debridement is achieved, thus  it is a complementary role in patient care.” By December 2020,  Dr. Mustapha Ahmed Yusuf has successfully  treated and discharged  30 patients who had chronic wounds on  Maggot Therapy at the Aminu Kano Teaching Hospital, Kano. This record which was achieved within a year, is likely to be broken in the coming months as more patients become aware of the proceedure and seek treatment in the teaching hospital. Dr Mustapha emphasised in the interview that  “Maggot Therapy as process of debridement /disinfecting of chronic wound achieves quick healing rate and reduces extended hospital stay. It is a standard treatment process being practised in the developed nations and some African countries for patients with chronic wounds such as diabetic ulcers osteomyelitis and necrotising fasciitis.”

He said that for years, the United Kingdom and United States of America have approved this method because it is a simple bedside procedure for which patient don’t have to be taken to the theatre to undergo surgery, and that even patient with electrolytes imbalance can be treated using maggots therapy. Indeed,  writing in an edition of the Journal for Diabetes Science and Technology, Dr. Ronald Sherman of the BioTherapeutics, Education and Research Foundation,  California, United States  of America pointed out that, “The medical literature is rapidly growing with scientific evidence demonstrating the efficacy and safety of maggot therapy for a variety of problematic wounds.”

Dr. Sherman added that, “Diabetic foot ulcers alone are so common, affecting approximately 15 per cent of the diabetes patient population (in the USA) that they account for over 1.5 million foot ulcers and at least 70,000 amputations annually. While technological advances have led to significant improvements in medical care, including wound care, nonhealing wounds still remain a significant problem. The annual cost of management for these wounds exceeds $20 billion. Worse yet, the prevalence of nonhealing wounds is on the rise.”

In  an article on ‘Extremity Amputation in Nigeria – A Review of Indications and Mortality,’   Dr.    O. A. Thanni  and  A. O. Tade of the  Olabisi Onabanjo University, Teaching Hospital, Sagamu, discovered that  “the most common indication for amputation in Nigeria is trauma,  complications of TBS, malignant tumours, diabetic gangrene, infections and peripheral artery disease. The uncommon causes are snakebite, congenital malformation, ainhum and chronic ulcers.”

With the introduction of Maggot Debridement Therapy in Nigeria by the Aminu Kano Teaching Hospital, Kano, under the watch of the Chief Medical Director, Professor Abdulrahnan Sheshe, there is hope that many Nigerians afflicted by ulcerous and  gangareous wounds, sores and snakebites can be saved from  such extremity amputation of their affected limbs.
