Lupus nephritis. Part I. Histopathological classification, activity and chronicity scores

CITATION: Bates, W. D. et al. 1991. Lupus nephritis. Part I. Histopathological classification, activity and chronicity scores. South African Medical Journal, 79:256-259.The original publication is available at http://www.samj.org.zaRenal biopsy has made a major contribution to the understanding and management of patients with lupus nephritis. In a 5-year retrospective study the renal morphology of 55 biopsies from 51 patients with lupus nephritis was classified acccrding to World Health Organisation criteria. In addition, semi-quantitative activity and chronicity scores were documented. The findings were similar to series from other parts of the world. Of the biopsies reviewed, 6 were class II, 13 class III, 32 class IV and 4 class V. In situations of overlap, segmental proliferative features determined the class to which a biopsy specimen was assigned. Twenty-five of the patients, all WHO class IV, showed activity scores in the severe range. Most of the activity score features were common and easily recognised but necrotising angiitis was only seen in 1 patient. Haematoxylin bodies were difficult to document and the nature and value of the haematoxylin body is questioned.Publisher’s versio

Lupus nephritis. Part II. A clinicopathological correlation and study of outcome

CITATION: Halland, A.-M. et al. 1991. Lupus nephritis. Part II. A clinicopathological correlation and study of outcome. South African Medical Journal, 79:260-264.The original publication is available at http://www.samj.org.zaA 5-year retrospective study of lupus nephritis at Tygerberg Hospital was performed in an attempt to document the clinical and histological spectrum of the disease and to study the outcome of the illness. Activity and chronicity scores were used in addition to the World Health Organisation classification system. Of 55 biopsies from 51 patients reviewed, 6 were class II, 13 class III, 32 class IV and 4 class V. There were 19 deaths and in 15 of these the histological classification was IV. Renal failure and infections, often with uncommon pathogens, were the most important causes of death. Serum creatinine values and creatinine clearance at the time of biopsy or follow-up, and hypertension at follow-up showed a significant relationship with outcome. WHO class IV was associated with a poor outcome (P= 0,048) when compared with the other WHO classes combined. Activity scores showed a significant relationship to the outcome (P = 0,018). The anticardiolipin antibodies IgG and IgM were not associated with WHO class or outcome. The study revealed a spectrum of histological results similar to that of other studies, with a high mortality rate, particularly in class IV disease. Poor renal function, persistent hypertension, histological classification IV, and high activity scores were found to be important prognostic indicators.Publisher’s versio

Bleeding peptic ulcer: characteristics and outcomes in Newcastle, NSW

Background: Peptic ulcer disease risk factors have changed, as has the impact of treatment on morbidity and mortality. Recent data on clinical presentation and outcome are sparse in Australia. Aim: To determine the characteristics and outcome of patients presenting with a bleeding peptic ulcer to a tertiary referral centre. Methods: We evaluated patients diagnosed with peptic ulcer bleeding between 2004 and 2008 at a tertiary referral hospital. Variables assessed included demographic data, comorbidities, medication use and Rockall score. Outcomes of interest were the time to endoscopy, peptic ulcer treatment, transfusion requirements, urgent surgery and survival. Results: Peptic ulcers were confirmed in 265 patients (55% male), of which 145 were gastric and 119 duodenal.The mean age was 71 years. On admission 38% of patients had haemodynamic instability and 92% had one or more comorbidity. Consumption of ulcerogenic medications at the time of admission was frequent (non-steroidal anti-inflammatory drugs (NSAIDs) 22%, aspirin 41%, clopidogrel or warfarin 10%) and proton pump inhibitors infrequent (15%). A gastroenterologist managed all patients according to their usual practice. Only a minority of patients received over three units of packed red cells. Few patients were referred for surgery (3%) or died (3%), but both events were significantly higher for the duodenal ulcer group. Conclusion: The characteristics and outcomes in patients with peptic ulcer bleeding have changed. Peptic ulcer disease remains a public health problem with modifiable risk factors, such as Helicobacter pylori infection and NSAIDs, which should be targeted to reduce the burden of illness

A case-control study of childhood trauma in the development of irritable bowel syndrome

Background: The etiology of irritable bowel syndrome (IBS) is not been fully elucidated, but childhood trauma may disturb the brain–gut axis and therefore be important. Thus, we conducted a family based case–control study of IBS cases and their relatives with the aims to (i) determine the frequency of childhood trauma among IBS cases and controls as well as their relatives, and (ii) assess childhood trauma among IBS cases with affected relatives (familial IBS). Methods: Outpatients with IBS, matched controls, and their first-degree relatives completed a self-report version of Bremner' Early Trauma Inventory. Percent of cases and controls with a family history were compared and odds ratios were computed using chi-squared test; recurrence risks to relatives were computed using logistic regression and generalized estimating equations. Key Results: Data were collected from 409 cases, 415 controls, 825 case relatives, and 921 control relatives. IBS cases had a median age of 50 and 83% were women. Of IBS cases, 74% had experienced any general trauma compared to 59% among controls, yielding an odds ratio of 1.56 (95% CI: 1.13–2.15, p < 0.008). There were no statistical differences between IBS relatives and control relatives with regards to lifetime trauma. Conclusions & Inferences: IBS is associated with childhood trauma, and these traumas often occur prior to onset of IBS symptoms. This provides further insight into how traumatic childhood events are associated with development of adult IBS

Short- and long-term outcomes for patients with variceal haemorrhage in a tertiary hospital

Background/Aim: To determine short- and long-term outcomes among a cohort of patients with variceal haemorrhage at a tertiary referral centre, and to determine the predictive value of the model for end-stage liver disease (MELD) score for mortality in these patients. Methods: Prospective database hospital audit that captured patients who presented with or were transferred with variceal haemorrhage between 2004 and 2008, and a retrospective review of long-term outcomes. Patients who presented to or were transferred to John Hunter Hospital, a tertiary referral hospital, with confirmed variceal bleeding were included. The main outcome measures were in-hospital, 6 weeks and end-of-audit mortality. We also recorded cause, location and degree of planning surrounding the deaths in this patient group. We analysed the MELD score for patients with complete survival data. Results: We recorded 93 episodes of variceal haemorrhage from 78 unique patients during the initial study period. The in-hospital mortality, 6 weeks mortality and end-of-audit mortality were 2.6, 9.0 and 59, respectively, and median survival time was 3.2 years (95% confidence interval 0.0, 6.1). The most frequent cause of death was related to complications of end-stage liver disease at 74%, followed by variceal bleeding (19%) and unknown (6%). A Cox proportional hazard model showed that the risk of mortality is increased by 1.06 (1.01–1.11) for each unit increase in MELD score. Conclusions: Short-term outcomes for patients with variceal bleeding continue to improve, but long-term prognosis remains guarded and should prompt further emphasis on advanced care planning to optimise patient care

Prevalence correlates and impact of fecal incontinence among older women

BACKGROUND: Fecal incontinence is a common problem that has been associated with anatomic, physiological, and medical conditions. There are very few data on the factors associated with fecal incontinence in elderly women. OBJECTIVES: We aimed to determine the factors associated with fecal incontinence via a population-based survey in a large cohort of elderly Australian women. DESIGN AND SETTING: Data from a large longitudinal population-based study of elderly Australian women aged 82 to 87 years were analyzed. PATIENTS: Participants were 5560 women (aged 82–87 years) who participated in the Australian Longitudinal Study on Women’s Health; 4815 women responded to questions relating to fecal incontinence. MAIN OUTCOME MEASURES: Fecal incontinence was defined as leakage of liquid and/or solid stool at least once per month over the past 12 months. Self-reported medical conditions and lifestyle factors as well as demographic factors were recorded. RESULTS: The prevalence of fecal incontinence was 10.4% (95% CI, 9.6–11.3) (n = 510). The prevalence was significantly higher among institutional- versus community-dwelling women (14.1% vs 9.7%; p = 0.0002). Univariately, lifestyle factors including fruit intake and fluid intake, along with a range of comorbidities, were associated. However, independent factors for fecal incontinence among community-dwelling women included diabetes mellitus (OR, 1.51; 95% CI, 1.14–2.01; p = 0.004), depression (OR, 1.84; 95% CI, 1.30–2.62; p = 0.001), urinary incontinence (OR, 2.29; 95% CI, 1.83–2.86; p < 0.0001), and osteoarthritis (OR, 0.73; 95% CI, 0.57–0.94; p = 0.013). Among institutional-dwelling women, however, we found urinary incontinence (OR, 4.43; 95% CI, 2.83–6.93; p < 0.0001) and poorer general health (OR, 0.98; 95% CI, 0.97–0.99; p = 0.003) to be independently associated. LIMITATIONS: This is a cross-sectional study, which prevents making conclusions about the cause and effect of observed correlations. CONCLUSIONS: The independent factors associated with fecal incontinence in this population do not appear readily modifiable, and many previously identified risk factors may not be important in the elderly women with fecal incontinence
