Epidemiological investigation out-of MP pneumonia and RWE out of 2003 to 2014

Epidemiological investigation out-of MP pneumonia and RWE out of 2003 to 2014

Mathematical research

All calculations were performed with SPSS V.14.0 (SPSS Inc.)parisons between groups were performed using the Student’s t-test, ? 2 test and Fisher’s exact test, and the data were expressed as mean±SD for continuous variables. A p value of <0.05 was considered statistically significant.


The fresh victims in the modern investigation were 793 customers with MP pneumonia and you may 384 customers with RWE in investigation months. To have epidemiological investigations, a whole 793 people were used, as the shown in the previously penned post.14 To have scientific evaluation amongst the teams, all in all, 501 MP pneumonia clients which were acknowledge throughout the brand new previous epidemics (241 cases in 2007–2006, and you can 260 cases last year), and 384 customers which have RWE was indeed analysed (contour step 1). Inside the investigation period, the number of accepted patients on the institution is a great complete twenty five 911 (but garden center customers). There had been everything 2100 accepted customers per year with a few variations in from year to year.

Most of MP pneumonia clients had realize-right up months at least three-years out of last crisis seasons out of 2011, nevertheless follow-up sufferers pleased with all of our possibilities requirements http://www.datingranking.net/pl/curves-connect-recenzja have been 180 among 501 cases about MP pneumonia classification and you can 206 one of 384 times regarding RWE category.

In the MP pneumonia people, there are clear episodes of cases within the 2003, 2006–2007 and 2011, with some circumstances happening regarding the interepidemic symptoms. There were relatively steady amounts of RWE cases annually throughout the study months. There have been no corresponding enhanced instances within the MP pneumonia epidemic ages but for the 2007 (profile 2). Zero MP pneumonia patient who had been readmitted due to MP reinfection over the epidemics was seen throughout investigation several months. The fresh mean years and ages delivery was in fact similar, as well as the peak age range was indeed dos–five years old in organizations (shape 3). During the seasonality away from one another groups, MP pneumonia are common inside decreasing order out-of fall, june, wintertime and you can spring season, if you find yourself customers having RWE were really commonplace in the trip, accompanied by spring, cold weather and you may june (study maybe not found).

Market and you will scientific qualities from MP pneumonia and RWE groups

Demographic, clinical and laboratory data in both groups are shown in table 1. The mean age and age distribution were similar in both groups as shown in figure 3 (5.4 years vs 5.6 years, p=0.312). Both groups had male predominance, and there were more males in the RWE group. As expected, cases with wheezing at presentation, the proportion of patients with history or family history of allergic diseases, and history of wheezing were higher in the RWE group. Recurrent wheezing after discharge was observed in 38 of 180 patients with MP pneumonia and 141 of the 206 patients with RWE (p<0.001).

In MP pneumonia patients, 52 of the total 501 patients (10.4%) had wheezing at presentation, 72 (14.4%) had a history of allergic diseases, 15 (3%) had RWE according to our definition and 40 (8%) had a family history of allergic diseases. When we divided the MP pneumonia patients into two groups of patients with wheezing (n=52) and without wheezing (n=449), the patients with wheezing were younger (3.7 years vs 5.6 years, p<0.001) and had higher proportions of history allergic diseases and wheezing history and higher values of leucocyte count and eosinophil differential (table 2). Among the 52 MP pneumonia patients with wheezing at admission, 10 were patient with RWE, while 42 had no previous RWE history. Thus, in this study, 66% (10 of 15) of patients with RWE history presented with wheezing, while 8.6% of patients without RWE history (42 of 486) had wheezing at presentation. In a follow-up study of patients who visited two or more times after discharge, 13 (including 5 cases of RWE) of 21 MP pneumonia patients with initial wheezing and 25 (including 2 cases of RWE) of 159 MP pneumonia patients without wheezing had at least one wheezing episode after discharge (table 2). Although not all patients were followed-up, it was estimated that at least 31 of the total MP pneumonia patients (n=501, 6.2%) showed a recurrent wheezing after initial MP infection.
