Chennai, April 30, 2024 – Apollo Cancer Centres (ACC) advocates raising awareness and addresses the challenges posed by the often-overlooked Primary Immunodeficiency Disorders (PIDs). In commemoration of the World Primary Immunodeficiency Week, observed from April 22nd to 29th, ACC spearheads discussions around this crucial health issue, shedding light on its prevalence and impact.

Primary Immunodeficiency Disorders represent a group of inherited conditions that compromise the body’s immune system, leaving individuals susceptible to infections. Shockingly, a significant portion of individuals with PIDs remain undiagnosed, leading to untreated complications and heightened risks. Despite the widespread impact of PIDs, there is alarmingly high mortality rates among affected infants, particularly those below one-year-old. Undiagnosed cases significantly contribute to this concerning statistic. While PIDs tends to be more severe in children, it can also affect adults, albeit with differing diagnostic challenges. In adults, the road to diagnosis may be prolonged, sometimes spanning up to 25 years from the onset of initial symptoms to an accurate PID diagnosis. This delay underscores the importance of heightened awareness and proactive screening initiatives to ensure timely medical intervention and improved outcomes for individuals affected by PID.

Over 6 million people globally suffer from PIDs, with an alarming 70-90% of cases remaining undiagnosed


In India, where consanguineous marriages are prevalent, the incidence of PIDs is notably high, exacerbating the challenge. It is estimated that there could be more than one million patients with PID in India. Since PID is a genetic condition, there is a chance of every pregnancy being affected. Prenatal diagnosis or testing the foetus at 10 to 11 weeks for pregnancy can help detect whether the foetus is affected or not and families need to be counselled accordingly.

According to WHO (World Health Organization and IUIS (International Immunological Societies), over 120 Primary Immunodeficiency Disorders (PIDs) exist, with antibody deficiencies like CVID (Common Variable Immunodeficiency), and XLA (X-linked Agammaglobulinemia), topping the list.

It wasn’t until Apollo Cancer Centre diagnosed and treated me for PIDs. Despite the fear, the medical team’s counselling provided immense comfort and I hope for a healthier future.”
