Atopic Manifestations: Dermatitis,Allergic Rhinitis and Asthma in Patients With Hypogammaglobulinemia

Background:

Most of the hypogammaglobulinemic patients have a clinical history in favor of allergic respiratory disease. Nevertheless, in these patients the importance and prevalence of atopic disorders have not been completely explained.

Objectives:

This study was aimed to evaluate atopic manifestations (dermatitis, allergic rhinitis and asthma) and pulmonary function in patients with hypogammaglobulinemia.

Patients and Methods:

We used the international study of asthma and allergies in childhood (ISAAC) questionnaire in forty-five patients diagnosed with hypogammaglobulinemia and spirometry was done in 41 patients older than 5 years.

Results:

Spirometry results were normal in 21 (51%), and showed obstructive in 15 (37%) and restrictive pattern in 5 (12%) of the 41 patients who were evaluated. By the end of the study, asthma was diagnosed in nine (20%) patients and other atopies (rhinitis and dermatitis) identified in 10 (22%), and four (9%), respectively.

Conclusions:

Atopic conditions should be investigated in the hypogammaglobulinemic patients and the prevalence in these patients may be higher than in normal population. Also, it is recommended to perform a pulmonary function test as a routine procedure in patients with hypogammaglobulinemia and atopy should be assessed in these patients.     

Incidence of Neonatal Hyperphenylalaninemia in Fars Province,South Iran

Objective

Phenylalanine hydroxylase or its cofactor, tetrahydrobiopterin (BH₄), deficiency causes accumulation of phenylalanine in body fluids and central nervous system. Considering the fact that hyperphenylalaninemia is a preventable cause of mental retardation in infants, the objective of this study was to determine the incidence of congenital hyperphenylalaninemia in Fars province, south of Iran.

Methods

In a period of one year from November 2007 to November 2008 blood samples were withdrawn from all newborns born in Fars province for measurement of serum phenylalanine. The samples with a serum level of≥ 2 mg/dl were referred to pediatric endocrine clinic for confirmation and determination of the type of hyperphenylalaninemia by quantitive serum phenylalanine measurements by using High-Pressure liquid chromatography (HPLC) method.

Findings

Nine out of 76966 newborns had a serum phenylalanine level≥2mg/dl, of which 8 cases were confirmed by HPLC. The incidence of the disease was 1:10000. The incidence of mild hyperphenylalaninemia and phenylketonuria (PKU) among the patients was 62.5% and 37.5% respectively and the incidence of BH₄ deficiency was 1/76966.

Conclusion

These findings indicate a high incidence of hyperphenylalaninemia, in the newborns from Fars province. The high incidence makes a comprehensive screening program for management of the disease necessary.     

Staphylococcus aureus bloodstream infections in children: A population-based assessment

BACKGROUND:

Although Staphylococcus aureus is a major cause of bloodstream infections, population-based data on these infections in children are limited.

OBJECTIVE:

To describe the epidemiology of S aureus bacteremia in children.

METHODS:

Population-based surveillance for all incident S aureus bacteremias was conducted among children (18 years of age or younger) living in the Calgary Health Region (Alberta) from 2000 to 2006.

RESULTS:

During the seven-year study, 120 S aureus bloodstream infections occurred among 119 patients; 27% were nosocomial, 18% health care associated and 56% community acquired. The annual incidence was 6.5/100,000 population and 0.094/1000 live births. A total of 52% had a significant underlying condition, and this was higher for nosocomial cases. Bone and joint (40%), bacteremia without a focus (33%), and skin and soft tissue infections (15%) were the most common clinical syndromes. Infections due to methicillin-resistant S aureus were uncommon (occurring in one infection) and three patients (2.5%) died.

CONCLUSIONS:

S aureus bacteremia is an important cause of morbidity in the paediatric age group. Underlying medical conditions and implanted devices are important risk factors. Methicillin-resistant S aureus and mortality rates are low.     

CT Findings in Pediatric Novel Influenza A (H1N1)-Associated Pneumonia

Objective

To explore CT findings in pediatric novel influenza A (H1N1)-associated pneumonia

Methods

We examined the CT findings in a series of six children with influenza H1N1-associated pneumonia.

Findings

In this series of cases, the predominant CT patterns were consolidations surrounded by ground glass opacities (GGOs) as well as isolated GGOs in all patients. Atelectasis was present in the right upper lobe (n=2) in three cases and pneumomediastinum in two.

Conclusion

In this series of cases, there may be no imaging differences between pediatric and reported adult influenza H1N1 cases and other viral pneumonia cases even with CT. Pneumomediastinum and atelectasis, especially in the right upper lobe, may frequently present in influenza H1N1-associated pneumonia as well as in other pediatric respiratory diseases.     

Th1/Th2 Cytokine Profile and Its Diagnostic Value in Mycoplasma pneumoniae Pneumonia

Background:

The levels of Th₁/Th₂ cytokine can alter in pathogenic infection in children with pneumonia.

Objectives:

To evaluate Th₁/Th₂ cytokine profile and its diagnostic value in M. pneumoniae pneumonia in children.

Patients and Methods:

Children with M. pneumoniae mono-infection and 30 healthy children were tested with cytokines assay. We used real time PCR to detect M. pneumoniae in children with pneumonia.

Results:

M. pneumoniae test was positive in 2188 (16.62%) out of 13161 pneumonia children. Children aged 5 - 9 years had the highest rate and summer was a season with high rate of M. pneumoniae incidence in Zhejiang province. During the course of study, in 526 pneumonia children with M. pneumoniae mono-infection and 30 healthy children cytokines assay was performed. IL-2 level of M. pneumoniae pneumonia children was lower than that of healthy children (median levels, pg/mL: IL-2: 3.2 vs. 5.7, P = 0.00), while IL-4, IL-10 and IFN-γ were higher than in healthy children (median levels, pg/mL: IL-4: 3.2 vs. 1.5, P = 0.00; IL-10: 5.6 vs. 2.5, P = 0.001; IFN-γ: 20.4 vs. 4.8, P = 0.001).

Conclusions:

IL-2 decreases and IL-4, IL-10 and IFN-γ increase in children with M. pneumoniae pneumonia, which has a promising prospect in diagnosis of this disease in clinical practice.     

Nephrotic Syndrome Following H1N1 Influenza in a 3-Year-Old Boy

Background

The pandemic influenza A/H1N1, spread through the world in 2009, producing a serious epidemic in Italy. Complications are generally limited to patients at the extremes of age (<6 months or >65 years) and those with comorbid medical illness. The most frequent complications of influenza involve the respiratory system.

Case Presentation

A 3-year-old boy with a recent history of upper respiratory tract infection developed a nephrotic syndrome. Together with prednisone, furosemide and albumin bolus, a therapy with oseltamivir was started since the nasopharyngeal swab resulted positive for influenza A/H1N1. Clinical conditions and laboratory findings progressively improved during hospitalization, becoming normal during a 2 month follow up.

Conclusion

The possibility of a renal involvement after influenza A/H1N1 infection should be considered.     

Maternal Folate and Vitamin B12 Status and Neural Tube Defects in Northern Iran: A Case Control Study

Objective

This study was conducted to determine the serum level of folic acid and vitamin B12 in neural tube defects pregnancies (NTD) and healthy controls in Northern Iran.

Methods

This case-control study was performed on women with neural tube defects pregnancies and controls with unaffected pregnancies in Northern Iran during 2006. Twenty three pregnant women whose pregnancies were diagnosed as NTD by a second-trimester ultrasonographic examination were recruited as cases. The control group (n=23) consisted of women who were selected among socio-economic status (SES) matched women who had a normal targeted ultrasound during the second trimester with documented normal fet al outcome. Fetal NTD was suspected with targeted second-trimester ultrasound during the 16^th week of gestation and confirmed with high maternal serum α-fetoprotein levels. Folate, vitamin B₁₂, homocysteine and alpha fetoprotein were evaluated after target ultrasonography.

Findings

Serum alpha fetoprotein level (mean±SD) in cases and controls was 120.2±64.1 and 50±33.5 iu/ml, respectively (P<0.05). The mean±SD folate in cases and controls was 8.4±4.2 versus 9.3±4.2 ng/ml, respectively. This difference was not significant. Folate deficiency was found in 30.4% of the cases and 13% of the controls (OR=2.9, 95%: 0.54–19.8). Vitamin B12 deficiency was found in 13% of cases and 17.7% of the controls (OR=0.7, 95%: 0.1-4.9).

Conclusion

This study showed that the probability of having a newborn with NTDs in maternal folate deficiency is three times higher than with normal folate in Northern Iran.     

New Single Nucleotide Deletion In the SMPD1 Gene Causes Niemann Pick Disease Type A in a Child from Southwest Iran: A Case Report

Objective

Niemann Pick disease (NPD) type A (NPA: MIM #257200) is a lipid storage disorder with an autosomal recessive inheritance and occurrs by defect of the SMPD1 gene encoding sphingomyelinase. Disruption of this enzyme leads to the accumulation of sphingomyelin in brain and liver, which in turn causes dysfunction or damage of tissue.

Methods

We report firstly a 2.5 year old boy with NPA in southwest Iran. Initially, the diagnosis was resulted on the basis of clinical symptoms. The genomic DNA of the suspected individual was subjected to exon sequencing of the SMPD1 gene. According to the human reference sequence {"type":"entrez-nucleotide","attrs":{"text":"NM_000543.4","term_id":"300795568","term_text":"NM_000543.4"}}NM_000543.4, a novel single guanine deletion resulting in a frameshift mutation (p.Gly247Alafs*9) was observed in the SMPD1 gene that might be causative for the outcome of the disease.

Findings

The present report is the first molecular genetics diagnosis of the NPA in southwest Iran. The detected deletion in the SMPD1 gene is remarkable because of its novelty.

Conclusion

Despite similar morbidity SGA infants exhibited higher lethal complication rates following delayed meconium passage compared to AGA infants.     

Thyroid Disorders in Children and Adolescents with Type 1 Diabetes Mellitus in Isfahan,Iran

Objective

Studies in different populations have shown great variation in the prevalence of thyroid diseases in patients with type 1 diabetes mellitus (T1DM). Our aim was to study the prevalence of thyroid disorders such as autoimmunity of thyroid (AIT), thyroid dysfunction, and goiter in children and adolescents with T1DM, compared with age- and sex-matched healthy controls in Isfahan.

Methods

One hundred patients with T1DM who were referred to Isfahan Endocrine and Metabolism Research Center and 184 healthy schoolchildren matched for age and sex were included. They were examined for goiter by two endocrinologists. Thyroid function test and serum thyroid antibodies (anti-TPO Ab and anti-Tg Ab) were measured.

Findings

The prevalence of subclinical hypothyroidism was high in both groups (18%). T1DM patients had lower frequency of goiter (21% vs. 38%, P=0.001), and higher prevalence of positive AIT (22% vs. 8%, P=0.001), anti-TPO Ab positivity (19.3% vs. 5.3%, P=0.000), and anti-Tg Ab (11.1% vs. 6.4%, P=0.1) in comparison with the control group. Being positive for AIT in diabetic patients meant an odds ratio of 5 (CI 95%: 1.5-15.6) for thyroid dysfunction. There was no association between age, sex, duration of diabetes and HbA_1C with serum anti-TPO Ab and anti-Tg Ab concentrations in this group.

Conclusion

Our results demonstrated the high prevalence of AIT and thyroid dysfunction in patients with T1DM. We suggest regular thyroid function and antibody testing in these patients.     

High-resolution computed tomography in young patients with cystic fibrosis: distribution of abnormalities and correlation with pulmonary function tests

Objective

To assess pulmonary abnormalities detected by high-resolution computed tomography (HRCT) in young children with cystic fibrosis (CF) and mild to moderate lung disease.

Study design

High-resolution computed tomography was performed in 60 children, 6 to 10 years old, with mild to moderate lung disease (forced expiratory volume in 1 minute [FEV₁], 52-137; mean, 102; SD, 15% predicted). HRCTs were scored by using a system that evaluates each lobe for severity and extent of CF lung disease. Findings of CF lung disease were tabulated in all subjects and in a subgroup with normal pulmonary function tests. HRCT scores were correlated with FEV₁, forced vital capacity (FVC), and forced expiratory flow between 25% and 75% of expired vital capacity (FEF_25-75) in 57 patients.

Results

Bronchiectasis was present in 35% of subjects, mucous plugging in 15%, and air trapping in 63%. No abnormality was detected in 25%. In 37 subjects with FEV₁, FVC, and FEF_25-75 >85% predicted, bronchiectasis was present in 30%. In 17% of these subjects, bronchiectasis was seen in ≥4 lobes. Correlations between HRCT scores and FEV₁ were significant and showed fair to moderate correlation (r = 0.36-0.46).

Conclusions

High-resolution computed tomography demonstrated a broad range of pulmonary abnormalities in young patients with CF with mild to moderate lung disease. In this study, abnormalities, including bronchiectasis, were common in young children with CF and normal pulmonary function tests.     

Reinfection Rate after Successful Helicobacter pylori Eradication in Children

Objective

Reinfection rate of Helicobacter pylori after successful eradication is low in developed countries. This study was performed to determine the reinfection rate of H. pylori during a follow up period of 12 months in Iranian children.

Methods

In this prospective study, children with H. pylori infection were treated with triple omeprazole based regimen. Patients with negative ¹³C urea breath test (UBT) performed after 8 weeks of therapy, were followed up by the same test after 1 year.

Findings

Thirty seven patients, aged 5 to 17 years, were studied. Among them 25 (67.5%) were boys. After eradication therapy of H. pylori, 34 patients had negative ¹³C UBT. Reinfection occurred in 5 (14.7%) patients. Reappearance or continuing symptoms after treatment were associated with higher rate of recurrence (P=0.042).

Conclusion

Recurrence rate of H. pylori was high in our children. Successful eradication significantly decreased complaints and further symptoms. Follow up and reevaluation of patients is necessary especially when there are symptoms after eradication.     

Flixweed vs. Polyethylene Glycol in the Treatment of Childhood Functional Constipation: A Randomized Clinical Trial

Background:

Polyethylene glycol (PEG) is often considered as the first-line treatment for functional constipation in children. Descurainia sophia (L.) Webb et Berth (D. sophia) is a safe recommended medicine in Iranian folk and Traditional Persian Medicine for the treatment of constipation.

Objectives:

To clinically compare D. sophia with PEG 4000 (without electrolyte) in pediatric constipation and to assess its efficacy and side effects.

Patients and Methods:

120 patients aged 2 - 12 years with constipation for at least 3 months were included in an 8 weeks lasting randomized controlled trial within two parallel-groups. Children received either PEG, 0.4 g/kg/day, or D. sophia seeds, 2 grams (for children aged 2 - 4 years) and 3 grams (for those aged > 4 years) per day.

Results:

A total of 109 patients completed the study (56 in D. sophia and 53 in PEG group). At the end of the study, 36 (64.3%) patients in D. sophia group and 29 (54.7%) in PEG group were out of Rome III criteria (P = 0.205). Median weekly stool frequency in 0, 1, 2, 3 weeks of the treatment was found to be 2, 5, 5, 5 in D. sophia and 3, 4, 4, 5 in PEG group (P = 0.139, 0.076, 0.844, 0.294), respectively. The number of patients who suffered flatulence was less (5, 8.9%) in D. sophia group as compared to PEG group (6, 11.3%) at the end of the trial (P = 0.461). D. sophia taste was less tolerated.

Conclusions:

D. sophia is introduced as a cheap and available medication which can be applied as a safe alternative to conventional PEG in the management of pediatric chronic functional constipation.     

Clinical and Genetic Features in Patients with Cystic Fibrosis in Southwestern Iran

Objective

Cystic fibrosis (CF) is a common autosomal recessive genetic disease caused by a mutation in the CF transmembrane conductance regulatory (CFTR) gene. This study attempted to identify the most common CFTR mutations and any correlations between certain mutations and the clinical presentation of the disease in CF patients in southwestern Iran.

Methods

Twenty nine common CFTR gene mutations were examined in 45 CF patients.

Findings

Chronic cough, intestinal obstruction, dehydration, heat exhaustion and steatorrhea were the most common early clinical symptoms among our patients. The most common mutation was ΔF508, with an allele frequency of 21%. The homozygous ΔF508 mutation was observed in eight patients (18%), and three patients (7%) were ΔF508 carriers. The 2183AA > G mutation was observed in four patients, one of whom was also a ΔF508 carrier. The R1162X mutation was detected in two patients. The G542X, R334W and N1303K mutations were detected each in one patient, the first of whom was also a ΔF508 carrier.

Conclusion

Out of 45 patients, 27 (60%) had none of the CFTR gene mutations we tested for. The most frequent mutations in southwestern Iranian patients with CF should be identified by sequencing the entire CFTR gene in order to optimize the design of a diagnostic kit for common regional mutations.     

Serum alpha1-fetoprotein in cystic fibrosis

In 38 children and adolescents with cystic fibrosis, in 19 normal children and 62 healthy adults the serum ₁-fetoprotein concentrations were measured by radioimmunoassay. In cystic fibrosis patients 97.5% and in normal children 95% of the ₁-fetoprotein values were within the normal range for healthy adults (1–9 ng/ml). Critical judgement of the reported findings in literature and our own results demonstrate that the investigation of ₁-fetoprotein in the serum cannot serve for detecting homozygotes of cystic fibrosis genes or heterozygote carriers.

---

Zusammenfassung Bei 38 Kindern und Jugendlichen mit cystischer Fibrose, 19 gesunden Kindern und 62 gesunden Erwachsenen wurden die Serumkonzentrationen des Alpha₁-Feto-proteins im Radioimmunoassay bestimmt. 97,5% der Alpha₁-Fetoprotein-Werte der Patienten mit cystischer Fibrose und 95% der Meßwerte der gesunden Kinder lagen innerhalb des Normbereiches (1–9 ng/ml), der für gesunde Erwachsene ermittelt worden war. Aufgrund unserer eigenen Untersuchungsergebnisse und bei kritischer Bewertung der bisher publizierten Befunde erscheint die Alpha₁-Fetoprotein-Bestimmung im Serum zur Erfassung der homozygoten und heterozygoten Genträger der cystischen Fibrose nicht geeignet.

     

Alpha 1 Antitrypsin Deficiency in Infants with Neonatal Cholestasis

Objective

Alpha1-antitrypsin deficiency (A1ATD) is the most important indication for liver transplantation in children. The gene frequencies vary in different ethnic groups. In the present study, we attempt to determine the frequencies of the most common defective alleles, Z and S, in Iranian children suffering from idiopathic neonatal cholestasis. Eighty-seven infants were typed for Z and S alleles.

Methods

In a single center study, 87 consecutive liver biopsies from infants with cholestasis were reviewed and patients with neonatal cholestasis enrolled in the study and cases with confirmed biliary tract atresia excluded. Formalin fixed paraffin embedded blocks were used for DNA extraction. AAT genotype was determined by polymerase chain reaction (PCR) assay and amplification of the two most common deficiency variants, S and Z alleles, and then sequencing of PCR products.

Findings

There were 48 (55.2%) males and 39 (44.8%) females, with a median age of 60 days. Out of 87 of the study subject, 2 (2.2%) were heterozygous for the S allele, and no ZZ, SS or MZ individual was found in the patients. No other polymorphism was found in the sequencing results.

Conclusion

In comparison to other populations, AAT deficiency seems not to be an important etiologic factor for neonatal cholestatic liver disease in Iran; however, further studies are recommended to estimate the true mutant gene frequencies.     

Saccharomyces Boulardii in Helicobacter Pylori Eradication in Children: A Randomized Trial From Iran

Background:

Helicobacter pylori infects around 50% of the human population and is asymptomatic in 70% of the cases. H. pylori eradication in childhood will not only result in peptic symptoms relief, but will also prevent late-term complications such as cancer. Today, probiotics are being increasingly studied in the treatment of gastrointestinal infections as an alternative or complement to antibiotics.

Objectives:

In this study we aimed to assess the effect of S. boulardii supplementation on H. pylori eradication among children in our region.

Patients and Methods:

In this randomized double-blind placebo-controlled clinical trial 28 asymptomatic primary school children with a positive H. pylori stool antigen (HpSA) exam were randomly allocated into the study group, receiving Saccharomyces boulardii, and the control group receiving placebo capsules matched by shape and size, for one month. The children were followed up weekly and were reinvestigated four to eight weeks after accomplished treatment by HpSA testing. The significance level was set at P < 0.05.

Results:

24 children completed the study. The mean HpSA reduced from 0.40 ± 0.32 to 0.21 ± 0.27 in the study group, indicating a significant difference (P = 0.005). However, such difference was not observed in the control group (P = 0.89). Moreover, the HpSA titer showed a 0.019 ± 0.19 decrease in the study group whereas the same value was 0.0048 ± 0.12 for the controls, again stating a significant difference (P = 0.01).

Conclusions:

Saccharomyces boulardii has a positive effect on reducing the colonization of H. pylori in the human gastrointestinal system but is not capable of its eradication when used as single therapy.     

Polymerase chain reaction detection of Kingella kingae in children with culture-negative septic arthritis in eastern Ontario

BACKGROUND:

The bacterium Kingella kingae may be an under-recognized cause of septic arthritis in Canadian children because it is difficult to grow in culture and best detected using molecular methods.

OBJECTIVES:

To determine whether K kingae is present in culture-negative joint fluid specimens from children in eastern Ontario using polymerase chain reaction (PCR) detection methods.

METHODS:

K kingae PCR testing was performed using residual bacterial culture-negative joint fluid collected from 2010 to 2013 at a children’s hospital in Ottawa, Ontario. The clinical features of children with infections caused by K kingae were compared with those of children with infections caused by the ‘typical’ septic arthritis bacteria, Staphylococcus aureus and Streptococcus pyogenes.

RESULTS:

A total of 50 joint fluid specimens were submitted over the study period. Ten were culture-positive, eight for S aureus and two for S pyogenes. Residual joint fluid was available for 27 of the 40 culture-negative specimens and K kingae was detected using PCR in seven (25.93%) of these samples. Children with K kingae were significantly younger (median age 1.7 versus 11.3 years; P=0.01) and had lower C-reactive protein levels (median 23.8 mg/L versus 117.6. mg/L; P=0.01) than those infected with other bacteria.

CONCLUSIONS:

K kingae was frequently detected using PCR in culture-negative joint fluid specimens from children in eastern Ontario. K kingae PCR testing of culture-negative joint samples in children appears to be warranted.     

Evaluation of Serum and Pleural Levels of Angiopoietin-1 and Angiopoietin-2 in Children with Transudative and Exudative Pleural Effusions

Objective

Angiopoietins are involved in the pathogenesis of a variety of human diseases. We tried to evaluate the application of pleural and serum Angiopoietin-1 and 2 in categorizing pleural effusions (PEs) into exudates and transudates in children.

Methods

Pleural fluid (PF) and serum Angiopoietin (Ang)-1 and Ang-2 were measured in 80 children with PEs (40 transudative and 40 exudative) by using enzyme-linked immunosorbent assay.

Findings

PF Ang-2 levels were significantly higher in pleural exudates than in transudates (P 0.012). PF Ang-2 levels were significantly higher than serum Ang-2 levels in patients with pleural exudates and transudates (P<0.001). PF Ang-2 levels were higher in tuberculous than in non-tuberculous pneumonic PEs and empyema (P=0.01). PF Ang-2 levels correlate with serum Ang-2 levels (P<0.003). PF Ang-1 levels were significantly lower than serum Ang-1 levels both in patients with exudates and those with transudates (P<0.001). Cutoff points of serum and PF Ang-2, differentiating between transudative and exudative effusions were 3ng/ml and 8ng/ml respectively. Predictive potentials of serum and PF Ang-2 cutoff points were: Sensitivity 90% and 95% respectively, specificity 92.50% and 97.50% respectively, positive predictive value 92.30% and 97.40% respectively and negative predictive value 90.20% and 95.10% respectively.

Conclusion

Ang-2 levels were elevated in exudative PEs and correlated with levels of markers of pleural inflammation and pleural vascular hyperpermeability. It could categorize PE to exudates and transudates with valuable discriminative properties. That was detected more obviously in pleural fluids than in serum.     

Eradication of Helicobacter pylori in Children by Triple Therapy Regimens of Amoxicillin,Omeprazole, and Clarithromycin or Azithromycin

Background and Objectives:

The present study aimed to evaluate the effect of classical and azithromycin-containing triple therapy eradication regimen against H. Pylori in children, and to determine the level of patients’ tolerance.

Patients and Methods:

This single clinical trial was performed in 2014 on 2 to 15 years old children. All children, in whom H. Pylori infection was confirmed through multiple biopsies of the stomach and required treatment, were enrolled in the study. H. Pylori-positive patients were treated alternately with two different drug regimens; Group OCA received clarithromycin 7.5 mg/kg/day every 12 hours for 10 days, amoxicillin 50 mg/kg/day every 12 hours for 10 days, and omeprazole 1 mg/kg/day every 12 hours for two weeks, and Group OAA received azithromycin 10 mg/kg/day once a day (before meal) for 6 days along with amoxicillin and omeprazole. Four to six weeks after completion of treatment, patients’ stool was tested for H. Pylori through the monoclonal method using the Helicobacter antigen quick kit.

Results:

There were no significant differences between the two groups regarding gender and age of patients. Based on ITT analysis, the therapeutic response in the OAA and OCA groups were 56.2% and 62.5%, respectively (P = 0.40). Drug adverse effects were 15.6% in the OCA and 3.1% in the OAA group (P = 0.19).

Conclusions:

The therapeutic response was seen in more than half of the patients treated with triple therapy of H. Pylori eradication regimen including azithromycin or clarithromycin, and there was no significant difference between the two treatment groups.
