“…Furthermore, it may be that the pharyngeal swabs special for virus preservation decreased the MP/ CP detection rate compared with sputum samples used in other studies, and the single sampling may also decreased detection rate. Some other studies reported that children younger than 3 years, which are the majority in our study, are rarely infected by MP or CP (Almasri et al, 2011, Kamata et al, 2011.…”

This study aimed to find novel information concerning pathogen detection and some probable coinfection factors in hand, foot, and mouth disease (HFMD). In this study, 1104 clinically diagnosed HFMD patients were included. Enterovirus 71 (EV71), coxsackievirus A16 (CA16), and 14 different respiratory pathogens were examined from nasopharyngeal swabs using polymerase chain reaction (PCR) or reverse transcriptase PCR (RT-PCR). To evaluate the immune activation in HFMD patients, 8 cytokines and IgM antibodies to EV71 and CA16 from mild and severe patients were detected. Our results indicated that the severity of HFMD may affect the pathogen detection. The lower positive rates of enterovirus and respiratory viruses in severe HFMD cases by RT-PCR were probably related to stronger immune response. Therefore, immunological tests such as ELISA are essential supplements to PCR or RT-PCR in order to increase pathogen diagnosis in HFMD, especially in severe cases.

Immunoglobulin M for Acute Infection: True or False?

Immunoglobulin M (IgM) tests have clear clinical utility but also suffer disproportionately from false-positive results, which in turn can lead to misdiagnoses, inappropriate therapy, and premature closure of a diagnostic workup. Despite numerous reports in the literature, many clinicians and laboratorians remain unaware of this issue. In this brief review, a series of virology case examples is presented. However, a false-positive IgM can occur with any pathogen. Thus, when an accurate diagnosis is essential for therapy, prognosis, infection control, or public health, when the patient is sick enough to be hospitalized, or when the clinical or epidemiologic findings do not fit, IgM detection should not be accepted as a stand-alone test. Rather, whenever possible, the diagnosis should be confirmed by other means, including testing of serial samples and the application of additional test methods.

There is a well-known correlation between Herpes simplex (HSV) infection and erythema multiforme (EM). More recently, in Japan, it was found that Chlamydia pneumoniae (Cp) may promote the development of EM. All cases of Cp infection-associated EM that had been diagnosed in our clinic over the past two years (from 2011 to 2012) were analyzed. Cp infection was diagnosed on the basis of a significant increase (>2.00) in anti-Cp IgM titers, as measured by the HITAZYME-ELISA test. There were 7 cases of Cp-EM, one male and 6 females. Median age was 13 years (range 3-29 years). It is recommended that the possible involvement of Cp infection, besides HSV or Mycoplasma pneumoniae infections, should be considered in all cases of EM.
