Introduction

Upper respiratory tract infection, defined as a generic term of acute inflammation in the nasal cavity, pharynx, or larynx, is a common acute respiratory infection (1,2). Due to their still developing immune function, children have weaker protection against bacterial invasion, with those younger than 5 years old being susceptible to upper respiratory tract infection. Diarrhea is a common complication of upper respiratory tract infection in children. It is mainly caused by immune system disorder, bacterial invasion, or common colds, with those in critical condition occasionally suffering from convulsions, acute abdominal pain, or other effects, which cumulatively pose a significant threat to children’s physical and mental health (3,4). The risk of respiratory tract infection in children with diarrhea is significantly increased. According to related reports, under the same environmental conditions, the risk of respiratory tract infection in children with diarrhea is 28% higher than that in normal children. Cefuroxime axetil, a commonly used antibiotic drug has a good therapeutic effect on the treatment of upper respiratory tract infection precipitated by a variety of pathogenic bacteria. Xingpi Yanger granules are a Chinese patent medicine, whose activity includes clearing away heat and toxic materials, relieving diarrhea, nourishing the blood, and tranquilization, and can be used to treat acute and chronic diarrhea caused by intestinal flora disturbance. When using antibiotics to treat respiratory tract infections in children, antibiotics should be used regularly to avoid the occurrence of antibiotic resistance, and a series of side effects caused by excessive use of antibiotics should also be paid attention to. Pay attention to the combination of drug treatment and the increase of physical resistance to avoid over-treatment. With the aim providing a better reference for clinical treatment, we investigated the effects of cefuroxime axetil combined with Xingpi Yanger granules on the treatment of upper respiratory tract infection accompanied by diarrhea in children. We present the following article in accordance with the CONSORT reporting checklist (available at https://dx.doi.org/10.21037/tp-21-314).

Methods

General information

A total of 124 children with upper respiratory tract infection accompanied by diarrhea admitted to the department of pediatrics in Baoji maternal and child health care hospital from May 2019 to May 2020 were enrolled and divided into a study group (n=62) and a reference group (n=62), according to admission number. The study is a parallel study and allocation ratio is 1:1. All procedures performed in this study involving human participants were in accordance with the Declaration of Helsinki (as revised in 2013). The study was approved by ethics board of Baoji maternal and child health care hospital (No.: 2018121403) and informed consent was taken from all the patients.

Inclusion criteria

The inclusion criteria were as follows: (I) children met the diagnostic criteria of upper respiratory tract infection and diarrhea as outlined in the 17th edition of the Nelson Textbook of Pediatrics (5); (II) children had diarrhea lasting for more than 1 day and that required medical treatment; and (III) according to the conditions of approval mandated by the Hospital Ethics Committee, the children and their family members all signed the informed consent.

Exclusion criteria

The exclusion criteria were as follows: (I) children had severe diseases of the respiratory system, nervous system, or urinary system; (II) children had systemic infection or infections on other sites, and (III) children had poor mental status or treatment compliance and could not cooperate with others.

Study methods

In the reference group, the children received routine clinical treatment by the means of placing ice bags on children’s heads, using ethanol to wipe the areas around the great vessels (e.g., the axilla, groin, neck), or advising them to drink more warm water (6,7). In addition to physical cooling, the children were given ibuprofen suspension (State Food and Drug Administration approval number H19991011; Shanghai Johnson and Johnson Pharmaceutical Co., Ltd., Shanghai, China) orally no more than 4 times a day at 5–10 mg/kg until their body temperature returned to normal. The children were also given ribavirin granules (State Food and Drug Administration approval number H20066463; Sunflower Pharmaceutical Group Defeier Co., Ltd., Hengshui, China) orally, at 10 mg/kg, 3 times a day, along with live combined Bifidobacterium and Lactobacillus tablets (State Food and Drug Administration approval number S19980004; Inner Mongolia Shuangqi Pharmaceutical Co., Ltd., Inner Mongolia, China), 2 tablets each time and 3 times each day. In addition, depending on each child’s condition, intravenous infusion was carried out to correct electrolyte levels and maintain acid-base balance (8,9).

In addition to above treatment in the control group, the children in the study group were administered cefuroxime axetil dispersible tablets (State Food and Drug Administration approval number H20030854; Guangzhou Nucien Pharmaceutical Co., Ltd., Guangzhou, China) 0.125 g each time, twice each day. Furthermore, the children were also given Xingpi Yanger granules (State Food and Drug Administration approval number Z20025415; Guizhou Jianxing Pharmaceutical Co., Ltd, Guiyang, China); the granules were mixed with warm water. The administration protocol for the Xingpi Yanger granules was follows: children younger than 1 year: 2 g each time and twice each day; children aged 1–2 years old: 4 g each time and twice each day: children aged 3–6 years old: 4 g each time and 3 times per day. The children in both groups underwent 3 consecutive treatment cycles, with 1 cycle lasting 3 days.

Observation indices

The evaluation of clinical efficacy is detailed in . The dehydration correction time, antipyretic time, antidiarrheal time, and total treatment time were recorded and compared between the 2 groups (secondary outcome). Five milliliters of fasting venous blood was collected from the children in both groups before treatment (T0), 1 day after treatment (T1), 3 days after treatment (T2), and 7 days after treatment (T3). After centrifugation, the upper serum was collected, and gastrin (GAS) (primary outcome), motilin (MOT) expression levels (primary outcome) in the serum samples were detected by using a multimode reader (HED-SY96S, Shandong Horde Electronic Technology Co., Ltd., Weifang, China) with auxiliary kits. Meanwhile, the somatostatin (SS) levels (primary outcome) were acquired by radioimmunoassay. The adverse reactions between the 2 groups were also compared.

Discussion

Upper respiratory tract infection is mainly caused by the invasion of various pathogenic bacteria, including viruses and bacteria, and studies have reported that most children are subject to secondary bacterial infection; therefore, the combination of antiviral and antibacterial therapy should be carried out in clinical treatment (10-12). Additionally, upper respiratory tract infection is characterized by a critical onset and high recurrence rate—reaching up to over 10 times annually—which seriously affects children’s growth, development, and their daily life. Treatment of this disease has thus become a major concern of pediatricians (13-15). In addition, the invasion of pathogenic bacteria incurred by upper respiratory tract infection can also lead to immune system disorders, which mainly manifest as an alteration in intestinal flora, meaning diarrhea is a common complication of upper respiratory tract infection. The affected children with diarrhea mostly present with increased frequency of defecation, changed stool shapes, and, in some severe cases, are even accompanied by different degrees of vomiting, abdominal pain, and other symptoms, or dehydration caused by an acid–base imbalance in their bodies (16). Generally, children with diarrhea have an acute and rapid progression; consequently, timely targeted drug treatment according to children’s clinical symptoms should be conducted to improve treatment effects.

Moreover, the regulation of the balance of intestinal flora should be prioritized in the treatment of upper respiratory tract infection accompanied by diarrhea in children (17,18). Xingpi Yanger granules, are a commonly used Chinese medicinal compound preparation for the treatment of upper respiratory tract infection in children. This compound has fewer side effects and higher clinical safety than do other drugs and exerts the effects of invigorating the spleen to eliminate dampness, regulating intestinal hormones and enhancing stronger adsorption of pathogenic bacteria, reducing the damage of pathogenic bacteria to the intestinal gastric mucosa to a certain extent, relieving intestinal clinical symptoms, and promoting the treatment of diarrhea (19-21). Cefuroxime axetil is a cephalosporin antibiotic, and its mechanism of action is to inhibit the synthesis of the bacterial cell wall by covalently binding to bacterial transpeptidase, which leads to bacterial death; it can also bind to penicillin to inhibit the formation of the bacterial cross-linking wall in the proliferation phase and kill bacteria in the reproduction phase; therefore, it is often used to treat upper respiratory tract infection caused by various bacteria. Cefuroxime axetil has good oral absorption and broad-spectrum antibacterial activity. Cefuroxime axetil has been widely used in the treatment of upper respiratory tract infections and diarrhea. The treatment of cefuroxime axetil in patients with upper respiratory tract infection and diarrhea can effectively remove bacteria in patients with good tolerance, safe and reliable curative effect, and has important clinical application value (22,23). GAS and MOT increased and SS decreased in children with pneumonia secondary diarrhea, indicating that there were changes in gastrointestinal hormones in children with diarrhea. Gastrointestinal hormones can significantly affect the secretion, movement and absorption of gastrointestinal tract, biliary tract and pancreas, and play a certain role in the pathophysiology of diarrhea. Xingpi Yanger granule has obvious regulatory effect on GAS, MOT and SS in children with pneumonia secondary diarrhea. The clinical effect of Xingpi Yanger granule was good, and the serum gastrin, plasma motilin and somatostatin were close to normal after treatment. MOT can stimulate the motility of intestinal smooth muscles, GAS is a hormone secreted by the mucosa of the small intestine that can increase the secretion of gastric acid and the contraction of antrum, and SS is a common inhibitory hormone that can reduce the basal level of gastric acid and relieve the peristalsis of the gastrointestinal tract in patients to some extent (24). In this study, the results revealed that serum GAS and MOT levels at T1, T2, and T3 in the study group were significantly lower than those in the reference group, whereas the SS levels at T1, T,2 and T3 in the study group were significantly higher than those in the reference group, indicating that cefuroxime axetil combined with Xingpi Yanger granules could lower serum GAS and MOT levels, improve SS levels, delay the peristalsis of the gastrointestinal tract, and reduce the occurrence of diarrhea. Pedata et al. (25) reported that after the children with pneumonia accompanied by diarrhea were treated with Xingpi Yanger granules, the serum MOT levels after treatment (448.71±13.42 µg/L) were significantly lower than those before treatment (583.29±42.66 µg/L), indicating that Xingpi Yanger granules can inhibit the secretion of serum MOT and improve intestinal function in children.

In conclusion, cefuroxime axetil combined with Xingpi Yanger granules can effectively improve gastrointestinal function in children with upper respiratory tract infection accompanied by diarrhea with significant clinical efficacy and high safety, and is thus worthy of application and promotion.
