Lophomonas blattarum infection in immunocompetent patient

Lophomonas blattarum (L. blattarum) is a protozoan parasite living in intestinal tracts of termites and cockroaches. Chen and Meng from China repoted first case of pulmonary L. blattarum infection in 1993. 137 cases have only been reported in literature between 1993 to 2013. Majority of these infections occur in immunocompromised patients and have been reported from China. We report a case of this rare entity in an immunocompetent young Indian male.

“…However, presence of L. blattarum, which has similar morphology like other protozoal forms, has been reported in some studies [2–4, 12]. A detailed review based on extensive search of PubMed and Google Scholar about L. blattarum and bronchopulmonary protozoal infections has recently been published [13]. …”

Flagellated protozoa that cause bronchopulmonary symptoms in humans are commonly neglected. These protozoal forms which were presumed to be “flagellated protozoa” have been previously identified in immunosuppressed patients in a number of studies, but have not been certainly classified so far. Since no human cases of bronchopulmonary flagellated protozoa were reported from Turkey, we aimed to investigate these putative protozoa in immunosuppressed patients who are particularly at risk of infectious diseases. Bronchoalveolar lavage fluid samples of 110 immunosuppressed adult patients who were admitted to the Department of Chest Diseases, Hafsa Sultan Hospital of Celal Bayar University, Manisa, Turkey, were examined in terms of parasites by light microscopy. Flagellated protozoal forms were detected in nine (8.2%) of 110 cases. Metronidazole (500 mg b.i.d. for 30 days) was given to all positive cases and a second bronchoscopy was performed at the end of the treatment, which revealed no parasites. In conclusion, immunosuppressed patients with bronchopulmonary symptoms should attentively be examined with regard to flagellated protozoa which can easily be misidentified as epithelial cells.

“…[1] which concludes that, “In the past 20 years, all the diagnosed cases as pulmonary Lophomonas blattarum infection reported in our country were misdiagnosed. Currently, there is no evidence to show Lophomonas blattarum as a pathogen resulting in pulmonary infection.” This conclusion is at odds with a literature review in which we identified 61 case reports of pulmonary L. blattarum [2]. …”
