Sensor-augmented CSII therapy with predictive low-glucose suspend following total pancreatectomy.

Pancreatogenic diabetes is characterised by recurrent severe hypoglycaemia due to changes in both endocrine and exocrine functions. There are no guidelines to manage these individuals. Herein, we describe the post-operative management of two people who developed pancreatogenic diabetes following total pancreatectomy for neuroendocrine malignancy. In both individuals, diabetes was managed using sensor-augmented predictive low-glucose suspend continuous subcutaneous insulin infusion (CSII). We demonstrate the benefit of sensor-augmented CSII in averting hypoglycaemia whilst optimising glycaemic control. Expected rates of severe hypoglycaemia in individuals with pancreatogenic diabetes can be averted with the use of continuous glucose monitoring (CGM) technology, optimising quality of life and reducing the risk of diabetes-related complications. LEARNING POINTS: There are no clear guidelines to manage people with pancreatogenic diabetes.We describe the use of CGM with predictive low-glucose suspend continuous subcutaneous insulin infusion (CSII) in the management of two individuals post-pancreatectomy.Predictive low-glucose suspend technology can achieve excellent glycaemic control whilst avoiding recurrent and severe hypoglycaemia in people with pancreatogenic diabetes.Predictive low-glucose suspend CGM should be considered as an effective therapeutic option for the management of pancreatogenic diabetes.

Gaps and barriers in health-care provision for co-morbid diabetes and chronic kidney disease: a cross-sectional study.

BACKGROUND: Patients with diabetes and chronic kidney disease (CKD) are a complex subset of the growing number of patients with diabetes, due to multi-morbidity. Gaps between recommended and received care for diabetes and chronic kidney disease (CKD) are evident despite promulgation of guidelines. Here, we document gaps in tertiary health-care, and the commonest patient-reported barriers to health-care, before exploring the association between these gaps and barriers. METHODS: This cross-sectional study recruited patients with diabetes and CKD (eGFR < 60 mL/min/1.73 m2) across 4 large hospitals. For each patient, questionnaires were completed examining clinical data, recommended care, and patient-reported barriers limiting health-care. Descriptive statistics, subgroup analyses by CKD stage and hospital, and analyses examining the relationship between health-care gaps and barriers were performed. RESULTS: 308 patients, of mean age 66.9 (SD 11.0) years, and mostly male (69.5%) and having type 2 diabetes (88.0%), participated. 49.1% had stage 3, 24.7% stage 4 and 26.3% stage 5 CKD. Gaps between recommended versus received care were evident: 31.9% of patients had an HbA1c ≥ 8%, and 39.3% had a measured blood pressure ≥ 140/90 mmHg. The commonest barriers were poor continuity of care (49.3%), inadequate understanding/education about CKD (43.5%), and feeling unwell (42.6%). However, barriers associated with a failure to receive items of recommended care were inadequate support from family and friends, conflicting advice from and poor communication amongst specialists, the effect of co-morbidities on self-management and feeling unmotivated (all p < 0.05). CONCLUSIONS: Barriers to health-care varied across CKD stages and hospitals. Barriers associated with a deviation from recommended care were different for different items of care, suggesting that specific interventions targeting each item of care are required.

Outcomes of twin pregnancies complicated by gestational diabetes: a meta-analysis of observational studies.

OBJECTIVE: Gestational diabetes mellitus (GDM) in singleton pregnancy is associated with large for gestational age neonates and adverse perinatal outcomes; however, the impact of GDM in twin pregnancy is unclear. Thus, the aim of this study is to assess the perinatal outcomes of twin pregnancies complicated by GDM by performing a meta-analysis of observational studies. STUDY DESIGN: Studies investigating GDM in twin pregnancy were identified through an online search of three databases: Medline, Embase and Web of Science. Selection criteria comprised full paper observational studies (retrospective or prospective) published in English that examined GDM in twin pregnancy compared with non-GDM twin pregnancy and reported on birth weight and/or adverse perinatal outcomes. Random-effects models with inverse-variance weighting were used to calculate standardized mean differences and unadjusted odds ratios. Sensitivity analyses were carried out to determine the impact of possible maternal confounders (body mass index and age) and GDM diagnostic criteria on perinatal outcomes. RESULTS: Thirteen observational studies were included. GDM twins were born at the same gestation as non-GDM twins, with marginally lower birth weight. There was no difference in the incidence of large or small for gestational age neonates. Although there was no correlation between GDM in twin pregnancy and respiratory distress, neonatal hypoglycemic or low Apgar score, GDM twins had a higher rate of neonatal intensive care unit admission (OR 1.49; 95% confidence interval: 1.10, 2.02; P<0.01). CONCLUSION: Identification and subsequent treatment of GDM in twin pregnancy demonstrates a similar risk of adverse perinatal outcomes compared with non-GDM twin pregnancies.

Clinical use of the co-formulation of insulin degludec and insulin aspart.

AIMS: To provide a review of the available data and practical use of insulin degludec with insulin aspart (IDegAsp). Premixed insulins provide basal and prandial glucose control; however, they have an intermediate-acting prandial insulin component and do not provide as effective basal coverage as true long-acting insulins, owing to the physicochemical incompatibility of their individual components, coupled with the inflexibility of adjustment. The molecular structure of the co-formulation of IDegAsp, a novel insulin preparation, allows these two molecules to coexist without affecting their individual pharmacodynamic profiles. METHODS: Clinical evidence in phase 2/3 trials of IDegAsp efficacy and safety in type 1 and type 2 diabetes mellitus (T1DM and T2DM) have been assessed and summarised. RESULTS: In people with T2DM, once- and twice-daily dosing provides similar overall glycaemic control (HbA1c ) to current modern insulins, but with lower risk of nocturnal hypoglycaemia. In prior insulin users, glycaemic control was achieved with lower or equal insulin doses vs. other basal+meal-time or premix insulin regimens. In insulin-naïve patients with T2DM, IDegAsp can be started once or twice-daily, based on individual need. People switching from more than once-daily basal or premix insulin therapy can be converted unit-to-unit to once-daily IDegAsp, although this strategy should be assessed by the physician on an individual basis. CONCLUSIONS: IDegAsp offers physicians and people with T2DM a simpler insulin regimen than other available basal-bolus or premix-based insulin regimens, with stable daytime basal coverage, a lower rate of hypoglycaemia and some flexibility in injection timing compared with premix insulins.

Efficacy and safety of canagliflozin when used in conjunction with incretin-mimetic therapy in patients with type 2 diabetes.

AIMS: To assess the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, in patients with type 2 diabetes enrolled in the CANagliflozin cardioVascular Assessment Study (CANVAS) who were on an incretin mimetic [dipeptidyl peptidase-4 (DPP-4) inhibitor or glucagon-like peptide-1 (GLP-1) receptor agonist]. METHODS: CANVAS is a double-blind, placebo-controlled study that randomized participants to canagliflozin 100 or 300 mg or placebo added to routine therapy. The present post hoc analysis assessed the efficacy and safety of canagliflozin 100 and 300 mg compared with placebo in subsets of patients from CANVAS who were taking background DPP-4 inhibitors or GLP-1 receptor agonists with or without other antihyperglycaemic agents at week 18. RESULTS: Of the 4330 patients in CANVAS, 316 were taking DPP-4 inhibitors and 95 were taking GLP-1 receptor agonists. At 18 weeks, canagliflozin 100 and 300 mg provided larger placebo-subtracted reductions in glycated haemoglobin (HbA1c) in patients taking DPP-4 inhibitors [-0.56% (95% confidence interval [CI]: -0.77, -0.35), and -0.75% (95% CI: -0.95, -0.54), respectively] and GLP-1 receptor agonists [-1.00% (95% CI: -1.35, -0.65), and -1.06% (95% CI: -1.43, -0.69), respectively]. Body weight and blood pressure (BP) reductions were seen with canagliflozin versus placebo in both subsets. Higher incidences of genital mycotic infections and osmotic diuresis-related adverse events (AEs) were seen with canagliflozin compared with placebo. The incidence of hypoglycaemia was numerically higher with canagliflozin versus placebo; nearly all events occurred in patients on background insulin or insulin secretagogues. CONCLUSIONS: In patients on background incretin mimetics, canagliflozin improved HbA1c, body weight and BP, with an increased incidence of AEs related to SGLT2 inhibition.

Risk Knowledge in Relapsing Multiple Sclerosis (RIKNO 1.0)--Development of an Outcome Instrument for Educational Interventions.

BACKGROUND: Adequate risk knowledge of patients is a prerequisite for shared decision making but few attempts have been made to develop assessment tools. Multiple Sclerosis (MS) is a chronic inflammatory disease of young adults with an increasing number of partially effective immunotherapies and therefore a paradigmatic disease to study patient involvement. OBJECTIVE/METHODS: Based on an item bank of MS risk knowledge items and patient feedback including perceived relevance we developed a risk knowledge questionnaire for relapsing remitting (RR) MS (RIKNO 1.0) which was a primary outcome measure in a patient education trial (192 early RRMS patients). RESULTS: Fourteen of the RIKNO 1.0 multiple-choice items were selected based on patient perceived relevance and item difficulty indices, and five on expert opinion. Mean item difficulty was 0.58, ranging from 0.14 to 0.79. Mean RIKNO 1.0 score increased after the educational intervention from 10.6 to 12.4 (p = 0.0003). Selected items were particularly difficult (e.g. those on absolute risk reductions of having a second relapse) and were answered correctly in only 30% of the patients, even after the intervention. CONCLUSION: Despite its high difficulty, RIKNO 1.0 is a responsive instrument to assess risk knowledge in RRMS patients participating in educational interventions.

Mortality associated with primary hyperparathyroidism.

561 patients with primary hyperparathyroidism were followed between 1961 and 1994. Relative survival was compared to that of the Australian population studied during the same time interval. Mortality was significantly greater in the hyperparathyroid population (P<0.001). Mortality was not greater in the patients with serum calcium levels >3.00 mmol/L compared to those with a serum calcium levels <3.00 mmol/L. 113 patients did not have parathyroid surgery. Their relative survival was not significantly different from those who had surgery but their mean serum calcium and parathyroid hormone (PTH) levels were significantly lower than those who had surgery. A re-analysis of the 453 patients followed between 1972 and 2011 was carried out and a 20-year survival analysis made of those diagnosed between 1972 and 1981 and those diagnosed between 1982 and 1991. The latter group had significantly worse relative mortality than the former group (P<0.001) but was significantly older at the time of diagnosis (56.94 ± 14.83 vs 52.01 ± 13.58, P<0.001). The serum calcium and serum PTH levels were not significantly different between these two groups.

Red clover isoflavones enriched with formononetin lower serum LDL cholesterol-a randomized, double-blind, placebo-controlled study.

BACKGROUND: Although postmenopausal combined hormone replacement therapy reduces the risk of hip fracture, long-term use may be associated with an increased risk of breast cancer, and in women more than 10 years after menopause it is associated with an increased risk of cardiovascular disease. Isoflavones, because of preferential binding to estrogen receptor beta, may retain the beneficial effects on bone but lessen the adverse effects on the breast. OBJECTIVE: The objective of this study was to study the effects of an isoflavone obtained from red clover (Rimostil) on bone mineral density, and on low-density lipoprotein (LDL) cholesterol. DESIGN: In a double-blind, randomized, placebo-controlled trial, 50 mg of Rimostil was given to women who were menopausal for at least 1 year. Bone mineral density of the spine, femoral neck and forearm and serum LDL cholesterol were measured at baseline and at 6-month intervals. The duration of follow-up was 2 years. RESULTS: There was no beneficial effect of Rimostil on bone density at any site. There was a 12% fall in serum LDL cholesterol in the Rimostil-treated arm, which was significantly greater than the 2% drop seen in the control arm (P=0.005).

Healthcare professional requirements for the care of adult diabetes patients managed with insulin pumps in Australia.

BACKGROUND: Healthcare professional (HCP) time supporting insulin pump therapy (IPT) has not been documented, yet it is important in planning and allocating resources for effective care. AIM: This study aims to determine HCP time spent in IPT patient care to inform resource planning for optimal IPT delivery. METHODS: Twenty-four Australian adult IPT-experienced institutions (14 government funded, seven private, three both) collected data between April 2012 and January 2013 prospectively, including: patient demographics, HCP classification, purpose of HCP-patient interaction, interaction mode and HCP time with the patient. A subset of patients was tracked from pre-pump education until stable on IPT. RESULTS: Data on 2577 HCP-adult patient interactions (62% face-to-face, 29% remote, 9% administrative) were collected over 12.2 ± 6.4 weeks for 895 patients; age 35.4 ± 14.2 years; 67% female; 99% type 1 diabetes, representing 25% of all IPT patients of the institutions. Time (hours) spent on IPT interactions per centre per week were: nurses 5.4 ± 2.8, dietitians 0.4 ± 0.2 and doctors 1.0 ± 0.5. IPT starts accounted for 48% of IPT interaction time. The percentage of available diabetes clinic time spent on outpatient IPT interactions was 20.4%, 4.6% and 2.7% for nurses, dietitians and doctors respectively. Fifteen patients tracked from pre-pump to stabilisation over 11.8 ± 4.5 weeks, required a median (range) of 9.2 (3.0-20.9), 2.4 (0.5-6.0) and 1.8 (0.5-5.4) hours per patient from nurses, dietitians and doctors respectively. CONCLUSIONS: IPT patient care represents a substantial investment in HCP time, particularly for nurses. Funding models for IPT care need urgent review to ensure this now mainstream therapy integrates well into healthcare resources.

Use of dermal injection of activated protein C for treatment of large chronic wounds secondary to pyoderma gangrenosum.

BACKGROUND: Pyoderma gangrenosum (PG) is a systemic disease that presents with cutaneous necrotizing ulceration, producing deep necrotic ulcers, usually with a raised, undermined, violaceous border. Treatment typically involves high dose immunosuppressive drugs, but more recently anti-tumour necrosis factor and monoclonal antibodies have been used. Activated protein C (APC) stimulates wound healing in patients with treatment-refractory skin ulcers, possibly by stimulating angiogenesis and re-epithelialization, and preventing inflammation. AIM: To investigate whether APC may be beneficial as a treatment for ulcers related to cutaneous PG. METHODS: Two patients were recruited with a clinical history and physical and histopathological evidence of acute PG. A total of 400 µg (1.0 mL) of APC was injected subcutaneously into the dermal edge of necrotic PG ulcers weekly for a total treatment period of 6 weeks. Photographs were taken, and clinical progress, ulcer size and pain score were monitored during this period and after the cessation of treatment, at weeks 8 and 12. RESULTS: Over the 12 weeks of the trial, APC led to a reduction in wound size from 3.8 cm(2) to 0.8 cm(2) in patient 1 (78.9% decrease) and from 41 cm(2) to 16 cm(2) in patient 2 (70.0% decrease, respectively), and a reduction in pain scores from 10 to 0 (100% decrease) in both patients. CONCLUSION: Although this study has limited because of its small sample size and lack of a true placebo group, it does indicate that APC has potential as a therapeutic option for patients with chronic skin ulcers from PG.

Intensification of medication and glycaemic control among patients with type 2 diabetes - the ADVANCE trial.

AIMS: The aim of this study was to assess associations between patient characteristics, intensification of blood glucose-lowering treatment through oral glucose-lowering therapy and/or insulin and effective glycaemic control in type 2 diabetes. METHODS: 11 140 patients from the Action in Diabetes and Vascular disease: preterAx and diamicroN-MR Controlled Evaluation (ADVANCE) trial who were randomized to intensive glucose control or standard glucose control and followed up for a median of 5 years were categorized into two groups: effective glycaemic control [haemoglobin A1c (HbA1c) ≤ 7.0% or a proportionate reduction in HbA1c over 10%] or ineffective glycaemic control (HbA1c > 7.0% and a proportionate reduction in HbA1c less than or equal to 10%). Therapeutic intensification was defined as addition of an oral glucose-lowering agent or commencement of insulin. Pooled logistic regression models examined the associations between patient factors, intensification and effective glycaemic control. RESULTS: A total of 7768 patients (69.7%), including 3198 in the standard treatment group achieved effective glycaemic control. Compared to patients with ineffective control, patients with effective glycaemic control had shorter duration of diabetes and lower HbA1c at baseline and at the time of treatment intensification. Treatment intensification with addition of an oral agent or commencement of insulin was associated with a 107% [odds ratio, OR: 2.07 (95% confidence interval, CI: 1.95-2.20)] and 152% [OR: 2.52 (95% CI: 2.30-2.77)] greater chance of achieving effective glycaemic control, respectively. These associations were robust after adjustment for several baseline characteristics and not modified by the number of oral medications taken at the time of treatment intensification. CONCLUSIONS: Effective glycaemic control was associated with treatment intensification at lower HbA1c levels at all stages of the disease course and in both arms of the ADVANCE trial.

Low circulating protein C levels are associated with lower leg ulcers in patients with diabetes.

Activated protein C (APC) promotes angiogenesis and reepithelialisation and accelerates healing of diabetic ulcers. The aim of this study was to determine the relationship between the incidence of lower leg ulcers and plasma levels of APC's precursor, protein C (PC), in diabetic patients. Patients with diabetes who had a lower leg ulcer(s) for >6 months (n = 36) were compared with age-, type of diabetes-, and sex-matched subjects with diabetes but without an ulcer (n = 36, controls). Total PC was assessed using a routine PC colorimetric assay. There was a significantly (P < 0.001) lower level of plasma PC in patients with ulcers (103.3 ± 22.7, mean ± SD) compared with control (127.1 ± 34.0) subjects, when corrected for age and matched for gender and type of diabetes. Ulcer type (neuropathic, ischaemic, or mixed) was not a significant covariate for plasma PC levels (P = 0.35). There was no correlation between PC levels and gender, type of diabetes, HbA1c, or C-reactive protein in either group. In summary, decreased circulating PC levels are associated with, and may predispose to, lower leg ulceration in patients with diabetes.

Association of HbA1c levels with vascular complications and death in patients with type 2 diabetes: evidence of glycaemic thresholds.

AIMS/HYPOTHESIS: There is conflicting evidence regarding appropriate glycaemic targets for patients with type 2 diabetes. Here, we investigate the relationship between HbA(1c) and the risks of vascular complications and death in such patients. METHODS: Eleven thousand one hundred and forty patients were randomised to intensive or standard glucose control in the Action in Diabetes and Vascular disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE) trial. Glycaemic exposure was assessed as the mean of HbA(1c) measurements during follow-up and prior to the first event. Adjusted risks for each HbA(1c) decile were estimated using Cox models. Possible differences in the association between HbA(1c) and risks at different levels of HbA(1c) were explored using linear spline models. RESULTS: There was a non-linear relationship between mean HbA(1c) during follow-up and the risks of macrovascular events, microvascular events and death. Within the range of HbA(1c) studied (5.5-10.5%), there was evidence of 'thresholds', such that below HbA(1c) levels of 7.0% for macrovascular events and death, and 6.5% for microvascular events, there was no significant change in risks (all p > 0.8). Above these thresholds, the risks increased significantly: every 1% higher HbA(1c) level was associated with a 38% higher risk of a macrovascular event, a 40% higher risk of a microvascular event and a 38% higher risk of death (all p < 0.0001). CONCLUSIONS/INTERPRETATION: In patients with type 2 diabetes, HbA(1c) levels were associated with lower risks of macrovascular events and death down to a threshold of 7.0% and microvascular events down to a threshold of 6.5%. There was no evidence of lower risks below these levels but neither was there clear evidence of harm.

The motherhood choice: themes arising in the decision-making process for women with multiple sclerosis.

OBJECTIVE: This study aimed to determine the main themes and concerns for women with Multiple Sclerosis when considering motherhood. METHOD: Twenty women with multiple sclerosis from various stages in the decision-making process participated in focus-groups where information was gathered regarding their experiences of making this decision. RESULTS: The themes emerging most frequently during the decision-making process were: a) concerns about the mother's own health and well-being; b) well-being of the child; c) coping with parenting; d) societal attitudes; e) experiencing parenting and f) timing and pressure of the decision. CONCLUSION: The results indicate that information regarding the effect of MS on pregnancy and child-rearing and the effect of pregnancy on MS and its progression need to be made more accessible to women. Information would be a valuable resource for women going through this decision-making process.

Glargine is superior to neutral protamine Hagedorn for improving glycated haemoglobin and fasting blood glucose levels during intensive insulin therapy.

AIM: To compare glycaemic control and symptomatic hypoglycaemia rates with glargine versus neutral protamine Hagedorn (NPH) in poorly controlled type 1 diabetes patients. METHODS: Patients (n = 125) received preprandial insulin lispro and either glargine (n = 62) or NPH (n = 63) at bedtime for 30 weeks in a multicentre, randomized, single-blind (a blinded investigator made titration decisions) study. Basal insulin dosage was titrated to achieve fasting blood glucose (FBG) values < 5.5 mmol/L. RESULTS: Baseline characteristics were similar for the two groups (mean diabetes duration 17.5 +/- 10.1 years) except mean glycated haemoglobin (HbA(1c)), which was lower in the glargine versus NPH group (9.2 +/- 1.1% vs 9.7 +/- 1.3%; P < 0.02). At end-point, mean HbA(1c) was 8.3 versus 9.1% for the glargine versus NPH groups. Adjusted least-squares mean (LSM) change from baseline was -1.04 versus -0.51%, a significant treatment benefit of 0.53% for HbA(1c) in favour of glargine (P < 0.01). Mean baseline FBG were similar for the glargine and NPH groups (11.2 vs 11.4 mmol/L). The means for end-point FBG were 7.9 versus 9.0 mmol/L. Adjusted LSM change from baseline was -3.46 versus -2.34 mmol/L, with a significant difference of 1.12 mmol/L in favour of glargine (P < 0.05). There were similar total numbers of daytime mild, moderate or severe hypoglycaemia episodes in the two treatment arms. However, significantly fewer moderate or severe nocturnal hypoglycaemic episodes were observed in the glargine group (P = 0.04 and P = 0.02). CONCLUSION: Glargine is superior to NPH for improving HbA(1c) and FBG levels during intensive insulin therapy in patients with type 1 diabetes, and is associated with less severe nocturnal hypoglycaemia.

Short-term peaks in glucose promote renal fibrogenesis independently of total glucose exposure.

Postprandial hyperglycemia is implicated as a risk factor predisposing to vascular complications. This study was designed to assess recurrent short-term increases in glucose on markers of renal fibrogenesis. Human renal cortical fibroblasts were exposed to fluctuating short-term (2 h) increases to 15 mM d-glucose, three times a day over 72 h, on a background of 5 mM d-glucose. To determine whether observed changes were due to fluctuating osmolality, identical experiments were undertaken with cells exposed to l-glucose. Parallel experiments were performed in cells exposed to 5 mM d-glucose and constant exposure to either 15 or 7.5 mM d-glucose. Fluctuating d-glucose increased extracellular matrix, as measured by proline incorporation (P < 0.05), collagen IV (P < 0.005), and fibronectin production (P < 0.001), in association with increased tissue inhibitor of matrix metalloproteinase (MMP) (P < 0.05). Sustained exposure to 15 mM d-glucose increased fibronectin (P < 0.001), in association with increased MMP-2 (P = 0.01) and MMP-9 activity (P < 0.05), suggestive of a protective effect on collagen matrix accumulation. Transforming growth factor-beta(1) (TGF-beta(1)) mRNA was increased after short-term (90 min) exposure to 15 mM glucose (P < 0.05) and after 24-h exposure to 7.5 mM ? (P < 0.05). Normalization of TGF-beta(1) secretion occurred within 48 h of constant exposure to an elevated glucose. Fluctuating l-glucose also induced TGF-beta(1) mRNA and a profibrotic profile, however, to a lesser extent than observed with exposure to fluctuating d-glucose. The results suggest that exposure to fluctuating glucose concentrations increases renal interstitial fibrosis compared with stable elevations in d-glucose. The effects are, in part, due to the inherent osmotic changes.

Intravenous pamidronate in the treatment and prevention of osteoporosis.

BACKGROUND: Potent oral bisphosphonates are the mainstay of therapy for osteoporosis. However, there are patients who cannot have oral bisphosphonates (e.g. because of gastrointestinal side-effects). Therefore, we wanted to examine the effects of intermittent i.v. pamidronate (APD) on bone mineral density (BMD) in patients who needed bisphosphonate therapy but could not have oral bisphosphonates. AIM: To assess BMD before and after intermittent i.v. APD in patients requiring a bisphosphonate either for the prevention of osteoporosis on concurrent steroid therapy or for the treatment of osteoporosis. METHODS: This was a retrospective audit of 84 consecutive patients at risk of fractures commencing APD between October 1997 and May 2000. Patients were treated with intermittent i.v. APD. BMD as measured by dual-energy X-ray absorptiometry before and after APD was the main outcome. RESULTS: The mean length of treatment and mean total APD dose were 16.8 +/- 7.0 months and 186.1 +/- 79.5 mg respectively. The reasons for using APD were failure to qualify for oral bisphosphonates on the pharmaceutical benefits scheme due to lack of documented minimal trauma fractures (58%), symptomatic gastro--oesophageal disease (20%), intolerance of oral bisphosphonates (18%) and lack of efficacy of calcitriol (4%). Mean baseline T-score at lumbar (L) 2-4 spine and femoral neck were -1.54 +/- 1.22 and - 2.87 +/- 1.19, respectively. From baseline to after APD treatment, there was a significant increase in L2-4 BMD (0.883 +/- 0.175 vs 0.912 +/- 0.176 g/cm(2), P < 0.001, mean increase +3.5%), in femoral neck BMD (0.667 +/- 0.137 vs 0.680 +/- 0.134 g/cm(2), P= 0.001, mean increase +2.1%) and in trochanteric BMD (0.549 +/- 0.129 vs 0.566 +/- 0.132 g/cm(2), P < 0.001, mean increase +3.1%). One-third of the patients were on oral glucocorticoids at the time of the present study and they had a similar increase in BMD compared to patients not on gluco-corticoids. Mild side-effects occurred in seven patients, none of whom discontinued treatment. CONCLUSION: Intermittent APD increases BMD and may be a suitable alternative for patients who cannot have oral bisphosphonates.
