The efficacy of Pelargonium sidoides in the treatment of upper respiratory tract infections in children with transient hypogammaglobulinemia of infancy.

Transient hypogammaglobulinemia of infancy (THI), defined as prolongation of physiological hypogammaglobulinemia normally seen between the initial 3rd and 6th months of life, is one of the most common immune deficiencies of childhood. Recurrent upper respiratory tract infections (URTI) are rather common in this group of patients, and generally, antibiotic treatment is the usual choice, although viruses involved in most cases. Pelargonium sidoides extract a herbal drug with known immunmodulator, antiviral and antibacterial effects. In this randomized, placebo controlled, prospective, monocentric pilot study, 14 of 28 patients with a diagnosed THI, were given Pelargonium sidoides, while 14 were given placebo during the period of URTI. Before and after the treatment period of one week, complete blood count, prothrombin time, activated prothromboplastin time, serum alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transpeptidase, total and direct bilirubin levels were measured. Mothers were asked to fill in a questionnaire for the recovery of the clinical symptoms during the treatment. The results were evaluated and compared in both group to assess the effect of Pelargonium sidoides. As a conclusion, the Pelargonium sidoides group showed increased appetite. The Pelargonium sidoides were found to beneficial for the nasal congestion, recovery of daily and nocturnal cough but not found be significant. Further studies with large number of participants are necessary to highlight the effect of Pelargonium sidoides in children with transient hypogammaglobulinemia of infancy.
