I read with interest the case report by Periwal et al. on pulmonary embolism (PE) as the primary presenting feature of nephrotic syndrome (NS). The case in question could be confidently added to the increasing number of similar cases reported in the literature., Apart from increasing alertness of the clinicians on PE as an initial presentation of NS, I presume the case in question has indirectly sent another sound clinical message. It is well-known that proteinuria is a marker of chronic kidney diseases. The available data have pointed out that about those who did not have proteinuria, patients who tested positive for protein had a 3.4-fold increased risk of venous thromboembolism (VTE) (odds ratio 3.4, 95% confidence interval [2.4, 5.0]). Such association was found to be unchanged when adjusted for other risk factors. In an interesting American study, the electronic medical records were retrospectively reviewed to measure the percentage of patients with acute VTE, who had a urinalysis (UA) and/or an evaluation of 24 h urine protein collection or urine protein to creatinine ratio. The study showed that UA was done in 63% of patients on the same admission for VTE and in the remaining 26% at a later date. Proteinuria, on routine urinalysis, was identified in 54% of patients. However, only 19% of these patients with proteinuria on UA had a formal evaluation of urine protein excretion, either by 24 h collection or by spot protein to creatinine ratio. Among them, 28% had NS. The study concluded that patients suffering from VTE might have proteinuria if not frank NS. Therefore, it has been recommended that UA should be part of the routine evaluation of a patient with VTE to disclose underlying proteinuria and even NS. Similarly, I presume that the take-home message sent by the case in question was simply “don't forget to dip the urine in a patient with PE.”
