Long-Term Efficacy and Safety of Repeated Rituximab to Maintain Remission in Idiopathic Childhood Nephrotic Syndrome: An International Study.

BACKGROUND: Long-term outcomes after multiple courses of rituximab among children with frequently relapsing, steroid-dependent nephrotic syndrome (FRSDNS) are unknown. METHODS: A retrospective cohort study at 16 pediatric nephrology centers from ten countries in Asia, Europe, and North America included children with FRSDNS who received two or more courses of rituximab. Primary outcomes were relapse-free survival and adverse events. RESULTS: A total of 346 children (age, 9.8 years; IQR, 6.6-13.5 years; 73% boys) received 1149 courses of rituximab. A total of 145, 83, 50, 28, 22, and 18 children received two, three, four, five, six, and seven or more courses, respectively. Median (IQR) follow-up was 5.9 (4.3-7.7) years. Relapse-free survival differed by treatment courses (clustered log-rank test P<0.001). Compared with the first course (10.0 months; 95% CI, 9.0 to 10.7 months), relapse-free period and relapse risk progressively improved after subsequent courses (12.0-16.0 months; HRadj, 0.03-0.13; 95% CI, 0.01 to 0.18; P<0.001). The duration of B-cell depletion remained similar with repeated treatments (6.1 months; 95% CI, 6.0 to 6.3 months). Adverse events were mostly mild; the most common adverse events were hypogammaglobulinemia (50.9%), infection (4.5%), and neutropenia (3.7%). Side effects did not increase with more treatment courses nor a higher cumulative dose. Only 78 of the 353 episodes of hypogammaglobulinemia were clinically significant. Younger age at presentation (2.8 versus 3.3 years; P=0.05), age at first rituximab treatment (8.0 versus 10.0 years; P=0.01), and history of steroid resistance (28% versus 18%; P=0.01) were associated with significant hypogammaglobulinemia. All 53 infective episodes resolved, except for one patient with hepatitis B infection and another with EBV infection. There were 42 episodes of neutropenia, associated with history of steroid resistance (30% versus 20%; P=0.04). Upon last follow-up, 332 children (96%) had normal kidney function. CONCLUSIONS: Children receiving repeated courses of rituximab for FRSDNS experience an improving clinical response. Side effects appear acceptable, but significant complications can occur. These findings support repeated rituximab use in FRSDNS.

Liver complications of haemoglobin H disease in adults.

Haemoglobin H (HbH) disease is a type of non-transfusion-dependent thalassaemia. This cross-sectional study aimed at determining the prevalence and severity of liver iron overload and liver fibrosis in patients with HbH disease. Risk factors for advanced liver fibrosis were also identified. A total of 80 patients were evaluated [median (range) age 53 (24-79) years, male 34%, non-deletional HbH disease 24%]. Patients underwent 'observed' T2-weighted magnetic resonance imaging examination for liver iron concentration (LIC) quantification, and transient elastography for liver stiffness measurement (LSM) and fibrosis staging. In all, 25 patients (31%) had moderate-to-severe liver iron overload (LIC ≥7 mg/g dry weight). The median LIC was higher in non-deletional than in deletional HbH disease (7·8 vs. 2.9 mg/g dry weight, P = 0·002). In all, 16 patients (20%) had advanced liver fibrosis (LSM >7.9 kPa) and seven (9%) out of them had probable cirrhosis (LSM >11.9 kPa). LSM positively correlated with age (R = 0·24, P = 0·03), serum ferritin (R = 0·36, P = 0·001) and LIC (R = 0·28, P = 0·01). In multivariable regression, age ≥65 years [odds ratio (OR) 4·97, 95% confidence interval (CI) 1·52-17·50; P = 0·047] and moderate-to-severe liver iron overload (OR 3·47, 95% CI 1·01-12·14; P = 0·01) were independently associated with advanced liver fibrosis. The findings suggest that regular screening for liver complications should be considered in the management of HbH disease.

The effect of time interval of vaginal ring pessary replacement for pelvic organ prolapse on complications and patient satisfaction: A randomised controlled trial.

OBJECTIVES: Limited data are available on the effect of the time interval of vaginal ring pessary replacement for pelvic organ prolapse (POP). This study investigated the effect of different replacement intervals on complications and patient satisfaction. STUDY DESIGN: A double-blinded, randomized controlled trial was conducted in a tertiary urogynecology center. Women with a vaginal ring pessary for POP (stage I to IV) were randomly allocated to two groups: 3-monthly or 6-monthly ring pessary replacement. All women were blinded to the replacement interval. Investigators were blinded during outcome assessment. Subjects were followed up for 6 months. MAIN OUTCOME MEASURES: The primary outcomes were the complication rates and patient satisfaction scores at 6 months. Secondary outcomes were the change in patient-reported symptoms and staging of POP. RESULTS: Of 101 women were screened from June 2016 to November 2017, 60 were recruited and randomly allocated: 30 to the 3-monthly replacement group and 30 to the 6-monthly replacement group. The overall complication rate in the 6-monthly group was higher than that in the 3-monthly group at the third visit (9 [30%] vs. 3[10.3%]; OR 3.71; 95%CI 0.89-15.58), but the difference was not statistically significant (p = 0.061). There were no statistically significant differences between groups in patient satisfaction scores, other prolapse-related symptoms or staging of POP. CONCLUSIONS: We provide evidence on the effect of replacement interval for a vaginal pessary on complications and patient satisfaction. A higher complication rate was found in the 6-monthly group than in the 3-monthly group, although the difference was not statistically significant. Patient satisfaction scores were similar in both groups.

Use of Traditional and Complementary Medicine as Self-Care Strategies in Community Health Centers: Cross-Sectional Study in Urban Pearl River Delta Region of China.

In China, Community Health Centers (CHCs) are major providers of primary care services, but their potential in empowering patients' self-management capacity has not been assessed. This study aims to describe self-care practice patterns amongst CHC attendees in urban China.In this cross-sectional quantitative study, 3360 CHC patients from 6 cities within the Pearl Delta Region were sampled using multistage cluster sampling.Thirty-seven per cent had used with over-the-counter Chinese herbal medicines (OTC CHMs) in the past year and majority of respondents found OTC CHMs effective. OTC CHMs were more popular amongst those who needed to pay out of pocket for CHC services. Less than 10% used vitamins and minerals, and those with a lower socioeconomic background have a higher propensity to consume. Although doubts on their usefulness are expressed, their use by the vulnerable population may reflect barriers to access to conventional health care, cultural affinity, or a defense against negative consequences of illnesses. About 25% performed physical exercise, but the prevalence is lower amongst women and older people. Taiji seems to be an alternative for these populations with promising effectiveness, but overall only 6% of CHC attendees participated.These results suggest that CHCs should start initiatives in fostering appropriate use of OTC CHM, vitamins, and minerals. Engaging community pharmacists in guiding safe and effective use of OTC CHM amongst the uninsured is essential given their low accessibility to CHC services. Prescription of Taiji instead of physical exercises to women and older people could be more culturally appropriate, and the possibility of including this as part of the CHC services worth further exploration.

Patient Perceptions of Expression of Empathy From Chinese Medicine Clinicians in a Chinese Population: A Cross-Sectional Study.

This study aims to examine the level of empathy perceived by patients receiving care from herbalists, acupuncturists and massage therapists and to investigate the factors that influence levels of perceived empathy.Participants who were 18 years or above; able to provide written informed consent; and able to read and write in Chinese without assistance were included. A total of 514 participants sampled from charity and semipublic Chinese medicine (CM) clinics in Hong Kong were recruited to assess levels of empathy perceived during various length of consultations (1-20 minutes) by the Chinese Consultation and Relational Empathy Measure (Chinese CARE). Multiple linear regressions were conducted to evaluate the associations between perceived levels of empathy and the type of CM practitioner consulted and participants' demographic and health characteristics.The average Chinese CARE total score for participants consulting CM practitioners was 34.3 of a maximum of 50. After adjusting for participants' health and demographic characteristics, acupuncturists received the highest ratings (P < 0.001), whereas massage therapists (P < 0.001) scored the lowest of the 3 modalities. Participants receiving social benefits (P = 0.013), those with longer waiting times (P = 0.002), and those with shorter consultation durations (P = 0.020) scored significantly lower on the Chinese CARE.The level of empathy perceived by participants using CM was similar to results found for those in conventional care, in contrast to findings in other geographical settings, where a high level of perceived empathy was a major motivator for participants to choose complementary medicine.

The impact of cutting alcohol duties on drinking patterns in Hong Kong.

AIM: In an effort to promote Hong Kong as a global wine hub, the government eliminated duties on wine and beer in 2008. The changes in alcohol consumption patterns are examined. METHODS: Anonymous, cross-sectional telephone surveys on a random sample of Chinese male and female residents aged 18-70 were carried out in 2011 (n = 4800) and 2012 (n = 1001). These data were compared with those of a 2006 (n = 9896) baseline survey conducted before the excise tax elimination. RESULTS: Prevalence of those ever drinking alcohol significantly increased from the 2006 baseline level of 66.6% to 82.0% in 2011 and to 85.2% in 2012. Of note, 10.2% of ever drinkers within the 2012 sample reported consuming alcohol for the first time in or after 2008. Younger, more educated or more affluent parts of the population are more likely to be ever drinkers. Unexpectedly, prevalence of binge drinking in the population decreased slightly from the 2006 baseline of 9.0% to 7.1% in 2011 and to 7.3% in 2012. Quantity of alcohol reportedly consumed by individuals did not change, while alcohol abuse and alcohol dependence levels decreased. However, binge drinking prevalence among the unemployed has increased. Logistic regression showed that those with lower educational achievement and the unemployed have higher likelihood of binge drinking. CONCLUSION: The government appears to have achieved its objective of making Hong Kong a world center for alcohol trade. However, the resulting access locally to cheaper alcohol has been associated with an increase in the numbers of those drinking alcohol. There has been a trend toward more adults drinking alcohol and greater risk of harm to some disadvantaged groups.
