Mycophenolate mofetil in steroid-dependent idiopathic nephrotic syndrome

Background

Prospective studies have established the mycophenolate mofetil (MMF) efficiency in childhood idiopathic nephrotic syndrome (INS) but reports on the long-term outcome are lacking. Moreover, the search for factors influencing its efficiency would be useful to define its place among the other treatments.

Methods

We performed a monocentric retrospective study including 96 children with steroid-dependent INS followed for 4.7 years (median) (IQ 3–6) after the onset of MMF treatment. The characteristics of responder patients (n?=?74), as defined by a 50 % decrease of relapse rate and/or a 60 % decrease of steroid dose, and of non-responder patients (n?=?22) were compared by univariate analysis and multivariate logistic regression.

Results

Withdrawal of prednisone was achieved in 48/96 patients after a median duration of 18.1 months (IQ 7.8–30.0) of MMF. Only 26/48 patients did not relapse under MMF alone. After MMF was stopped in these patients, only six remained in remission without any treatment at last follow-up. Responders had a shorter time to remission at the first flare (9.5 vs. 15 days, p?=?0.02), a shorter disease duration prior to the onset of MMF (22.2 vs. 94.5 months, p?=?0.001), and were younger at the MMF initiation (6.7 vs. 10.1 years, p?=?0.02) than non-responder patients. The age of MMF initiation was an independent factor associated with efficiency (OR?=?0.80, 95 % CI [0.69, 0.93], p?<?0.01).

Conclusions

MMF is more efficient in young patients treated early in the disease course. Nevertheless, MMF has no remnant effect while nearly all patients relapsed after withdrawal of the drug.

     

Association between vaginal bulge and anatomical pelvic organ prolapse during pregnancy and postpartum: an observational study

Introduction and hypothesis

Pelvic organ prolapse (POP) is defined as the coexistence of anatomical POP and relevant symptoms. Vaginal bulge is the symptom most closely associated with the anatomical condition in nonpregnant women. Even if childbearing is a major risk factor for the development of POP, there is scant knowledge on the prevalence of specific POP symptoms, and how these symptoms relate to anatomical POP during pregnancy and postpartum. The aim of this study was to explore whether vaginal bulge symptoms were associated with anatomical POP in pregnancy and postpartum, and to present the prevalence of vaginal bulge symptoms throughout this period.

Methods

A prospective observational study was carried out following 300 nulliparous pregnant women with repeat assessments from mid-pregnancy until 1 year postpartum. Symptoms of vaginal bulge defined as the sensation of a vaginal bulge inside and/or outside the vagina were assessed by electronic questionnaires. Anatomical POP defined as pelvic organ prolapse quantification system (POP-Q) stage ≥2 has been presented in a previous publication and showed a range of 1–9%. The association between the symptom vaginal bulge and anatomical POP at the various visits was analyzed using Fisher’s exact test.

Results

Prevalence of vaginal bulge ranged between 16 and 23%. At 6 weeks postpartum the symptom was associated with anatomical POP; otherwise, these two features were unrelated.

Conclusions

The symptom vaginal bulge was barely associated with anatomical POP, and cannot identify anatomical POP in pregnancy or postpartum.

     

Posttraumatic Stress Disorder Following Diagnosis of Multiple Sclerosis

The Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) recognizes life-threatening illness as a potential stressor that can precipitate posttraumatic stress disorder (PTSD). This study represents the first study of PTSD in the context of having a diagnosis of multiple sclerosis (MS). Fifty-eight MS patients were administered the Clinician Administered PTSD Scale, the Geriatric Depression Scale, and Disease Steps Questionnaire. Nine participants (16%) met symptom criteria for PTSD. In terms of those who satisfied the reexperiencing criterion, 75% of participants reported intrusions related to future-oriented concerns about their prognosis. These findings suggest that a significant proportion of MS patients experience PTSD-type reactions. These results are discussed in terms of the suitability of the PTSD framework to account for the distinctive nature of stress reactions secondary to life-threatening illness.     

Bring me home: Renal dialysis in the Kimberley

SUMMARY:   The incidence of end-stage renal failure (ESRF) in the Kimberley region at the top end of Western Australia far exceeds known national rates and trend analysis demonstrates a close parallel to what is occurring in the Northern Territory. Dialysis prevalence in the Kimberley has nearly tripled in the last decade and has increased at a much faster rate than the rest of Western Australia. Almost all of these people with ESRF are Aboriginal Australians living in remote communities.
In January 2004, the Western Australia Country Health Service and Kimberley Aboriginal Medical Services' Council, under the auspices of the Kimberley Aboriginal Health Planning Forum, embarked upon a review of renal disease in the Kimberley funded by the Western Australia Department of Health. The main purpose of the review was to identify the scope of the problem and make projections upon which to base programme and service development over the next 10 years.
This paper outlines the findings of the Review of Renal Disease in the Kimberley and presents, for the first time, regional data analysis and comparisons. In addition, future projections on the impact of ESRF and recommendations for improving current service delivery are discussed. Given the challenges of remoteness and individuals' desire to return home, this review recommends development of locally-based expertise capable of providing training and support to patients and their families, reinvigoration of community-based dialysis modalities, and the initiation of planning for a second satellite service in the Kimberley.     

Extended treatment of primary osteoporosis by sodium fluoride combined with 25 hydroxycholecalciferol

Summary Nineteen patients suffering from primary osteoporosis, all having at least one vertebral collapse, initially received 50 mg of sodium fluoride alone per day for 6–18 months. Subsequently fluoride was associated with 25–50g of 25 OH cholecalciferol (calcifediol) per day for 6–18 months in 12 of these patients and 9 were treated for 31–58 months. As control group, 9 patients were given placebo for 6–18 months. The effect of the treatment was assessed by three methods: 1) the metacarpal index (MI) determined by radiogrammetry, 2) the calcium content of the hand bone (Ca) measured by local neutron activation, 3) the iliac bone histomorphometry. MI and (Ca) did not change significantly at any time in any group. In each group there was a significant increase in trabecular bone volume, osteoid volume, osteoid surfaces and a significant decrease in mineralization fronts. On the other hand, the changes in osteoblastic surfaces, osteoclastic surfaces, number of osteoclasts/mm2 were not significant in any group. No change was observed in the placebo group. These data suggest that the increase in the trabecular volume of fluorided bone is mainly due to the increase in osteoid which itself is due to a bone mineralization defect despite the association of calcifediol. This is probably one of the reasons why (Ca) does not change significantly.     

Physical activity behaviour in children and adolescents before,during and after cancer treatment

Purpose

Childhood cancer survivors show reduced physical activity (PA) levels which may considerably impact child development, quality of life, social participation and sequelae such as functional and cardiovascular health. This study aims to evaluate different aspects of PA behaviour in patients with childhood cancer (PaC) before (bT), during (dT) and after (aT) cancer treatment.

Methods

In this cross-sectional, multicentre study, 114 PaC and 37 healthy controls between 4 and 20 years of age were enrolled. PA behaviour was assessed using an adapted questionnaire which included items asking about PA level, PA intensity and domains of PA.

Results

Patients reported lower PA levels and less minutes of PA at moderate-intensity dT than aT and bT (P?≤?0.05). Healthy controls reported higher PA levels than patients aT (P?≤?0.05). At school, 41.7% of PaC did not participate in physical education aT or bT. Lastly, 45.6% of PaC who were engaged in sport club activities bT did no more participate in sport club activities aT.

Conclusion

Patients reported different PA behaviours dT and aT than bT. Therefore, monitoring of PA should be considered to increase PA levels in PaC. Future studies also need to examine how PA behaviour can be influenced in a positive way in PaC.
