Fungal Infection Mimicking Spinal TB Found in 4 Covid-Recovered Patients
The discovery of a new post covid symptom among recovered patients in the last three months has raised serious concerns among the medical fraternity. The new cause of worry seems to be the detection of a fungal infection that has led to severe bone damage to the spinal-discs spaces of a patient.
The presence of this fungal infection came to the fore when a 66-year-old patient was found complaining of mild fever and severe lower back pain a month after recovering from COVID 19. Initially, the patient was treated with muscle relaxants and nonsteroidal anti-inflammatory drugs without relief.
A magnetic resonance imaging or MRI scan then revealed severe infection-led bone damage to the spinal-discs spaces called spondylodiscitis. Medically termed as aspergillus osteomyelitis, the invasive fungal infection was found to be difficult to diagnose as it mimics spinal tuberculosis (TB). Such fungal infection has been detected in mouth cavities of Covid-recovered patients, and, in rare cases, in lungs.
Deliberating on the issue, an infectious diseases expert told that so far vertebral osteomyelitis caused by aspergillus fungi species has been diagnosed in four patients in three months. Prior to this, vertebral osteomyelitis had not been documented in post-Covid patients in India, he added.
The common thread found in all four was that they had severe Covid and were treated with steroids to get over Covid-linked pneumonia and related complications. The expert contended that long-term use of corticosteroids may increase the risk of opportunistic infections, depending on the underlying disease being treated and what other drugs are being used.
Another rare yet critical fungal infection caused by a group of molds known as mucormycetes called mucormycosis has also been widely reported in recovered patients across India. These molds are present naturally in the environment. However, it affects humans when the body’s immunity system has been weakened and it is vulnerable. It affects the lungs and the sinuses following inhalation of fungal spores from the air. The fungus can also enter the body through open wounds or cuts. This infection is also said to be caused due to the long-term use of corticosteroids.
Earlier, a partial or temporary loss of voice was also detected among many Covid survivors. The experts contended that the condition which is causing hoarseness of voice in some victims due to lung fibrosis or a complete loss of speech for weeks is not directly caused due to the virus but because it is making the victims susceptible to larynx infections which are making them feeling choked.
This condition is said to set in between the first and third weeks of the Covid attack and may last up to 3 months. It has not cased caused a permanent loss of voice in anyone however, it has led to many of those suffering falls into depression.
