Cap polyposis is a rare and under-recognised cause of rectal bleeding in children. Our study has characterized the disease phenotype and treatment outcomes in a pediatric cohort.
Information on demographics, disease presentation, laboratory findings, radiological investigations, and endoscopic and histological findings were obtained from the patients' medical records.RESUlTS 32 patients were diagnosed with IBD, 30 of whom had Crohn's disease and 2 had ulcerative colitis. The incidence of IBD rose from an initial rate of 2.2 per 100,000 patients in the year 2000 to a peak of 11.4 patients per 100,000 patients by 2008. Median age of onset of symptoms was 10.5 years. There were more boys (63%) than girls in the group and a higher representation of Indians (34.4%). The most common presenting symptoms were abdominal pain (87.5%), diarrhoea (75.0%) and weight loss (71.9%). Extraintestinal manifestations such as fever and arthralgia were found in over 50% of patients. The most common physical findings were perianal abnormalities (56.3%), mouth ulcers (37.5%) and growth failure (15.6%). Abnormal laboratory findings such as low albumin, raised erythrocyte sedimentation rate, anaemia, thrombocytosis and high C-reactive protein were found in nearly half of the patients. Endoscopic and histological findings showed that a majority of patients (90.6%) also had evidence of inflammation in the upper gastrointestinal tract.CONClUSION Paediatric IBD is on the rise. The higher occurrence in Indians, earlier onset and more florid presentation may suggest different genetic and environmental influences specific to Asian children.
BackgroundExclusive enteral nutrition (EEN) is as effective as corticosteroids in inducing remission in children with Crohn’s disease (CD). However, over 50% of these children relapse by 12 months of diagnosis. Thiopurines are commonly prescribed as maintenance therapy for CD, but evidence for its efficacy is controversial. Data on the effectiveness of EEN in Southeast Asian (SEA) children with CD is scarce. This study aims to evaluate the efficacy of EEN induction therapy in a cohort of SEA children with newly diagnosed CD. The secondary aim was to evaluate concomitant early azathioprine (EAZ) use in determining remission rate at 6 and 12 months.MethodsCase records of all children with newly diagnosed CD from 2011 to 2014 were reviewed and relevant demographic as well as clinical data were extracted. The primary outcome measure was the number of patients who completed EEN induction therapy and achieved remission (Paediatric Crohn’s Disease Activity Index; PCDAI≤10). Factors influencing duration of remission were evaluated in particular early azathioprine (EAZ) defined as starting azathioprine within one month of diagnosis versus late azathioprine (LAZ) use.ResultsForty children with newly diagnosed CD were identified. Thirty-three children: 67% boys, median age 13y (range 3–17) completed 8 weeks of EEN induction therapy and 91% achieved remission. Significant improvements were seen in PCDAI scores (32.7 ± 9.2 to 4.2 ± 5.1; p < 0.001), mean BMI z-score (− 1.38 ± 1.57 to − 0.82 ± 1.27; p = 0.004) and baseline inflammatory markers: Erythrocyte Sedimentation Rate (51.6 ± 30.1 mm/h to 13.3 ± 7.1 mm/h; p < 0.0001) C-Reactive Protein (44.6 ± 51.0 mg/L to 5.2 ± 7.6 mg/L; p = 0.001), Albumin (30.7 ± 7.5 g/L to 38.7 ± 3.9 g/L; p < 0.0001), Platelets (464 ± 161 × 109 to 370 ± 111 × 109; p < 0.0001),. Early azathioprine initiation was associated with a remission rate of 80 and 73% at 6 and 12 months respectively. Remission was also maintained for longer duration in EAZ vs LAZ groups (p = 0.048).ConclusionEEN effectively induces remission in this cohort of SEA children with newly diagnosed CD. Early initiation of thiopurine with EEN induction therapy is effective in maintaining steroid-free remission for at least one year.
This is a case report of a 12-year-old returned traveler with typhoid and scrub typhus coinfection. The diagnosis of typhoid was made early with blood cultures and Widal Weil Felix serology. Persistent fever despite appropriate antibiotics for typhoid fever prompted a search for concomitant infection, which led to the diagnosis of scrub typhus confirmed by Orientia tsutsugamushi serology. The patient was given doxycycline with good clinical response. Scrub typhus infection should be an early consideration in the differential diagnoses of fever in a returned traveler from regions where it is endemic. Coinfections should be taken into consideration particularly when fever or symptoms persist despite adequate therapy for a previously identified microorganism.
