Diabetes mellitus is the leading cause of end-stage renal disease, and uncontrolled hyperglycemia is directly related to the increased mortality in this setting. As kidney function decreases, it becomes more challenging to control blood glucose since the risk of hypoglycemia increases. Decreased appetite, changes in glycaemia homeostasis, along with reduced renal excretion of anti-hyperglycemic drugs tend to facilitate the occurrence of hypoglycemia, despite the paradoxical occurrence of insulin resistance in advanced kidney disease. Thus, in patients using insulin and/or oral anti-hyperglycemic agents, dynamic adjustments with drug dose reduction or drug switching are often necessary. Furthermore, in addition to consider these pharmacokinetics alterations, it is of utmost importance to choose drugs with proven cardio-renal benefits in this setting, such as sodium-glucose co-transporter 2 inhibitors and glucagon-like peptide 1 receptor agonists. In this review, we summarize the indications and contraindications, titration of doses and side effects of the available anti-hyperglycemic agents in the presence of advanced diabetic kidney disease (DKD) and dialysis, highlighting the risks and benefits of the different agents. Additionally, basic renal function assessment and monitoring of glycemic control in DKD will be evaluated in order to guide the use of drugs and define the glycemic targets to be achieved. 相似文献

The objective of this study was to determine the prevalence, clinical spectrum, and outcome of paediatric HIV infection in 281 consecutive children admitted to hospital in rural South Africa between October 1996 and January 1997. HIV infection was defined as two positive ELISAs in those aged > 12 months; a positive ELISA plus a positive IgG3 in those aged 6-12 months; and a positive ELISA plus positive p24 antigen or PCR in those aged 0-5 months. In all, 72 (26 per cent) children were HIV infected. Age-specific HIV prevalence was at least 25 per cent in all 1-5 year age groups. HIV-infected children were more likely to have been previously admitted (46 per cent vs. 23 per cent; p = 0.0002), and were more likely to have severe malnutrition (52 per cent vs. 17 per cent; p < 0.0001). Both HIV-infected and HIV-uninfected most frequently presented with diarrhoeal disease (51 per cent vs. 32 per cent), acute respiratory infection (13 per cent vs. 23 per cent), and malnutrition (18 per cent vs. 11 per cent). Satisfactory response to antibiotic therapy was less likely among the HIV-infected (56 per cent vs. 73 per cent; p = 0.02), and mortality was higher among the HIV-infected (21 per cent vs. 7 per cent; p = 0.005). It is concluded that HIV-infected children present with disease syndromes common to this setting, but do so more frequently and with worse outcome than their uninfected counterparts. The high burden of paediatric HIV disease in this setting poses a substantial challenge for health resources. 相似文献

Cholesterol granulomas (CGs) are tumor-like lesions seldom encountered by neuropathologists. CGs develop in reaction to localized hemorrhage, often occurring in bony sites with possible impaired drainage of blood and blood products. The most common bony location is the petrous apex, although orbital, frontal sinus, and maxillary sinus sites have been reported. We compare and contrast three recent cases seen at our institution that illustrate the spectrum of clinical, radiographic, and pathologic features that can be seen with these mass lesions. One case demonstrated the unique pathological features of Gamma-Gandy body formation, epithelioid histiocytes heavily encrusted with iron pigments, and extensive tophi. The latter most likely represented aggregates of calcium pyrophosphate crystals associated with extensive iron deposition. 相似文献

OBJECTIVES: To determine hepatitis A seroprevalence and notification rates in Australia in order to inform vaccination policy. DESIGN: Seroprevalence was determined by cross-sectional survey of opportunistically collected sera; notifications were extracted from the National Notifiable Diseases Surveillance System. PARTICIPANTS: 3,043 serum samples collected in 1998 were obtained from 46 laboratories around Australia. Sample size in each age group was based on expected seroprevalence, and States and Territories were sampled proportionally to their population size. Males and females were equally represented. Notifications were extracted for cases with onset between 1 January 1991 and 31 December 1998. MAIN OUTCOME MEASURES: Seroprevalence and notifications were analysed by age, sex and State/Territory. RESULTS: 41.1% of serum samples were seropositive for hepatitis A (95% CI, 39.4%-42.9%) (population-weighted seroprevalence, 38.3%). Seroprevalence was significantly associated with increasing age (P<0.001), but did not differ between the sexes (male:female ratio, 1.04:1; 95% CI, 0.95-1.14). However, significantly more notifications were recorded for males than females (male:female ratio, 1.65:1; 95% CI, 1.60-1.70). The Northern Territory had the highest seroprevalence (68.8%; 95% CI, 52.7%-84.8%) and annual notification rates (48.7 per 100,000 population; 95% CI, 45.0-52.4 per 100,000). CONCLUSIONS: These data show that about half the Australian population has not been exposed to hepatitis A and is therefore susceptible to infection. However, any decision on national routine childhood hepatitis A vaccination requires a cost-benefit analysis. Routine vaccination of high-incidence communities remains controversial. 相似文献

The 1998 Australian Measles Control Campaign had as its aim improved immunization coverage among children aged 1-12 years and, in the longer term, prevention of measles epidemics. The campaign included mass school-based measles-mumps-rubella vaccination of children aged 5-12 years and a catch-up programme for preschool children. More than 1.33 million children aged 5-12 years were vaccinated at school: serological monitoring showed that 94% of such children were protected after the campaign, whereas only 84% had been protected previously. Among preschool children aged 1-3.5 years the corresponding levels of protection were 89% and 82%. During the six months following the campaign there was a marked reduction in the number of measles cases among children in targeted age groups. 相似文献
