To the Editor,

Unlike what is seen in children, adult minimal change disease (MCD) is a rare disease accounting for only 10-15% of cases of adult primary nephrotic syndrome (NS). [1],[2] Most cases of NS seen in adults are secondary to diabetes mellitus, connective tissue diseases, infections, malignancies, drugs or toxins.

Indeed in a city like Khartoum, various tropical allergens are expected to be present in the air, food, soil and from parasitic infestations which might be triggering agents for relapsing minimal change nephrotic syndrome. [3],[4],[5],[6] In general practice, an intensive work-up is done for all adults with NS to rule out a primary cause; this includes a detailed history, thorough clinical examination and an exhaustive list of general and specific investigations, considering the possibility an allergen-induced immune response as well. Once an adult is labeled as having a primary glomerular disease, an initial kidney biopsy is mandatory. Repeat biopsies are always considered in those who fail to respond to steroids or other immuno-suppressants. [7]

It seems interesting to look in depth in adults with relapsing MCNS, their serum IgE levels and their sensitivity to food antigens by skin testing, radioallergosorbent or basophil degranulation, though not commonly applied in clinical practice.

Overall, it is always important to consider an alternative diagnosis in adults with primary minimal change nephrotic syndrome, who fail to respond to treatment or follow an atypical course. [7]
