    After the devastating effects of the 2015 earthquake in Nepal, the provisions for safe drinking water, personal hygiene, and sewage management were compromised among displaced people living in temporary shelters. Typhoid fever is endemic in Kathmandu valley, which is transmitted among people by the faecal–oral route and outbreaks can occur in post-disaster situations. To reduce the risk of transmission and outbreaks, typhoid vaccine was introduced for young children and adolescents for whom the risk of typhoid fever was highest. With the collaboration of Siddhi Memorial Hospital, Nepal Paediatric Society, and Nagasaki University, a typhoid vaccination campaign was implemented in Bhaktapur district in the valley. The campaign was conducted in all 23 temporary camps in the district. Among 4,263 children aged 2 to 15 years, 4,216 (98.9%) received a single dose of the typhoid Vi polysaccharide vaccine. Most of the children (47.8%) were 11 to 15 years of age, and girls were 50.2%. Only four children (0.1%) had an adverse event following immunization (AEFI). Local camp leaders, public health officials, and local youth clubs participated in the immunization programme. In a review of admissions to the local children’s hospital, there was no apparent increase in typhoid cases in the post-earthquake period. Despite the various difficulties in the post-earthquake situation in Nepal in 2015, the vaccination campaign for the prevention of typhoid fever was successfully carried out among young children and adolescents

    Background: Among pneumococcal serotypes, some serotypes are more prevalent in the nasopharynx than others; determining factors for higher prevalence remain to be fully explored. As non-vaccine serotypes have emerged after the introduction of 7-valent conjugate vaccines, study of serotype specific epidemiology is in need. When two or more serotypes co-colonize, they evolve rapidly to defend host\u27s immune responses; however, a clear association of cocolonization with a clinical outcome is lacking. Methods: Children less than 5 years old who were admitted to hospital due to acute respiratory infections (ARI) (n = 595) and healthy children (n = 350) were recruited. Carriage of pneumococcus was determined by culture and lytA PCR in the nasopharyngeal samples. Serotype/serogroup detection and its quantification were done by the nanofluidic real time PCR system. Spearman\u27s correlation and logistic regression were used to examine a correlation of serotype/serogroup specific bacterial load with its prevalence and an association of co-colonization with ARI respectively. Results: Serotype/serogroup specific bacterial load was correlated with its prevalence, both in ARI cases (Spearman\u27s rho = 0.44, n = 186; P<0.0001) and healthy children (Spearman\u27s rho = 0.41, n = 115; P<0.0001). The prevalence of multiple serotypes was more common in ARI cases than in healthy children (18.5% vs 7.1%; aOR 2.92, 95% CI: 1.27-6.71; P = 0.01). The dominant serotype in the co-colonization had a 2 log10 higher bacterial load than the subdominant serotype, both in ARI cases (P<0.001) and healthy children (P<0.05). Conclusions: High bacterial load in the nasopharynx may help transmit pneumococci among hosts, and increase the chance of successful acquisition and colonization. Co-colonization of multiple serotypes of pneumococci is linked with ARI, which infers the interactions of multiple serotypes may increase their pathogenicity; however, they may compete for growth in number

    Background The emergence of multidrug-resistant (MDR) and extended-spectrum beta-lactamase (ESBL)-producing uropathogens has complicated the treatment of urinary tract infections (UTI). Paediatric UTI is a common illness, which if not treated properly, may lead to acute and long-term complications, such as renal abscess, septicaemia, and renal scarring. This study aimed to determine the prevalence of MDR and ESBL-producing uropathogens among children. Methods During the study period (April 2017–April 2018), midstream urine samples were collected following aseptic procedures from children < 16 years in Siddhi Memorial Hospital. Standard culture and biochemical tests were performed to identify uropathogens and antimicrobial susceptibility test was done by modified Kirby-Bauer disc diffusion method following Clinical and Laboratory Standard Institute (CLSI) guidelines. ESBL-producing uropathogens were screened by ceftazidime (30 μg) and cefotaxime (30 μg) discs, and confirmed by the combination disc tests: ceftazidime + clavulanic acid (30/10 μg) or cefotaxime + clavulanic acid (30/10 μg) as recommended by CLSI. Results We processed 5545 non-repeated urine samples from the children with symptoms of UTI. A significant growth of uropathogens was observed in 203 samples (3.7%). The median age of the children was 24 months (interquartile range (IQR), 12–53 months). Escherichia coli (n = 158, 77.8%) and Klebsiella pneumoniae (n = 30, 14.8%) were common among the uropathogens. Among them, 80.3% were resistant to amoxycillin and 51.2% were resistant to cotrimoxazole. Most of them were susceptible to amikacin, nitrofurantoin, and ofloxacin. MDR was detected in 34.5% (n = 70/203) and ESBL producers in 24.6% (n = 50/203) of them. The proportion of MDR isolates was higher in children < 5 years (n = 59/153, 38.6%) than children ≥ 5 years (n = 11/50, 22%) (P = 0.03). Conclusions Nitrofurantoin, ofloxacin, and amikacin can be used for the empirical treatment for UTI in children in Bhaktapur, Nepal. MDR and ESBL-producing uropathogens are prevalent; this warrants a continuous surveillance of antimicrobial resistance

    Background The nutritional status of children may deteriorate after natural disasters such as earthquakes. A 7.8 Richter scale earthquake struck Nepal in 2015 that affected 1.1 million children. Children whose homes were destroyed and had to live in temporary shelters were at risk of malnutrition. With the support of Nagasaki University School of Tropical Medicine and Global Health (TMGH) and Siddhi Memorial Hospital (SMH), we conducted a nutritional survey of under-5 children living in temporary shelters in Bhaktapur Municipality in 2015 immediately after the earthquake and a follow-up survey in 2017. Results We found 591 under-5 children living in 22 temporary shelters in 2015. A total of 285 children were followed up and re-assessed in 2017. In a paired analysis (n = 285), the prevalence of underweight children increased from 10.9% in 2015 to 14.0% in 2017 (P < 0.001), stunting increased from 26.7 to 31.9% (P = 0.07), and wasting decreased from 4.2 to 2.5% (P = 0.19). Conclusions Children who lived in temporary shelters after the 2015 Nepal earthquake might be at increased risk of a deterioration in nutritional status

    Identification of the causative pathogen in infectious diseases is important for surveillance and to guide treatment. In low- and middle-income countries (LMIC), conventional culture and identification methods, including biochemical methods, are reference-standard. Biochemical methods can lack sensitivity and specificity and have slow turnaround times, causing delays in definitive therapy. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) is a rapid and accurate diagnostic method. Most studies comparing MALDI-TOF MS and biochemical methods are from high-income countries, with few reports from LMIC with tropical climates. The aim of this study was to assess the performance of MALDI-TOF MS compared to conventional methods in the Philippines. Clinical bacterial or fungal isolates were identified by both MALDI-TOF MS and automated (VITEK2) or manual biochemical methods in the San Lazaro Hospital, Metro Manila, the Philippines. The concordance between MALDI-TOF MS and automated (VITEK2) or manual biochemical methods was analyzed at the species and genus levels. In total, 3530 bacterial or fungal isolates were analyzed. The concordance rate between MALDI-TOF MS and biochemical methods was 96.2% at the species level and 99.9% at the genus level. Twenty-three isolates could not be identified by MALDI-TOF MS. In this setting, MALDI-TOF MS was accurate compared with biochemical methods, at both the genus and the species level. Additionally, MALDI-TOF MS improved the turnaround time for results. These advantages could lead to improved infection management and infection control in low- and middle-income countries, even though the initial cost is high
