Procedural pain in patients with cancer: a Delphi expert management consensus.

OBJECTIVES: Diagnosis, treatment and care of cancer often involve procedures that may be distressing and potentially painful for patients. The PROCEDIO Study aimed to generate expert-based recommendations on the management of moderate to severe procedural pain in inpatients and outpatients with cancer. METHODS: Using a two-round Delphi method, experts from pain and palliative care units, medical and radiation oncology and haematology departments expressed their agreement on 24 statements using a 9-point Likert scale, which were classified as appropriate (median 7-9), uncertain (4-6) or inappropriate (1-3). Consensus was achieved if at least two-thirds of the panel scored within the range containing the median. RESULTS: With an overall agreement on the current definition of procedural pain, participants suggested a wider description based on evidence and their clinical experience. A strong consensus was achieved regarding the need for a comprehensive pre-procedural pain assessment and experts emphasised that healthcare professionals involved in procedural pain management should be adequately trained. Most panellists (98.2%) agreed that pharmacological treatment should be chosen considering the duration of the procedure. Transmucosal fentanyl (96.5%) and morphine (71.7%) were recommended as the most appropriate drugs. Oral and nasal transmucosal fentanyl were agreed as the most suitable for both outpatients and inpatients, while consensus was reached for intravenous and subcutaneous morphine for inpatients. CONCLUSIONS: These results provide updated expert-based recommendations on the definition, prevention and treatment of moderate to severe procedural pain, which could inform specialists involved in pain management of patients with cancer.

Psychometric properties of the Clarke questionnaire for hypoglycemia awareness in the Spanish population with type 2 diabetes.

OBJECTIVES: The Clarke questionnaire, validated in Spanish language, assesses hypoglycemia awareness in patients with type 1 diabetes. This study aimed to analyze its psychometric properties in patients with type 2 diabetes (T2DM). METHODS: This was a questionnaire validation study. Patients with T2DM and treated with insulin, sulfonylureas or glinides were consecutively recruited from six endocrinology consultations and six primary care centers. The internal structure of the 8-item Clarke questionnaire was analyzed by exploratory (training sample) and confirmatory (testing sample) factor analysis; the internal consistency using Omega's McDonald coefficient; and goodness of fit with comparative fit index (CFI, cutoff >0.9), Goodness of Fit Index (GFI, cutoff >0.9), and root mean-square error of approximation (RMSEA, cutoff <0.09), as well as unidimensionality indicators. RESULTS: The 265 participants (56.8% men) had a mean age of 67.8 years. Confirmatory factor analysis for one dimension obtained poor indicators: fit test (p < 0.001); CFI = 0.748; RMSEA = 0.122 and SRMR = 0.134. Exploratory factor analysis showed 2 or 3 dimensions with poor adjustment indicators. Omega's McDonald was 0.739. CONCLUSIONS: The Spanish version of the Clarke questionnaire was not valid or reliable for assessing hypoglycemia awareness in people with T2DM in Spanish population.

One-year longitudinal association between changes in dietary choline or betaine intake and cardiometabolic variables in the PREvención con DIeta MEDiterránea-Plus (PREDIMED-Plus) trial.

BACKGROUND: Choline and betaine intakes have been related to cardiovascular health. OBJECTIVES: We aimed to explore the relation between 1-y changes in dietary intake of choline or betaine and 1-y changes in cardiometabolic and renal function traits within the frame of the PREDIMED (PREvención con DIeta MEDiterránea)-Plus trial. METHODS: We used baseline and 1-y follow-up data from 5613 participants (48.2% female and 51.8% male; mean ± SD age: 65.01 ± 4.91 y) to assess cardiometabolic traits, and 3367 participants to assess renal function, of the Spanish PREDIMED-Plus trial. Participants met ≥3 criteria of metabolic syndrome and had overweight or obesity [BMI (in kg/m2) ≥27 and ≤40]. These criteria were similar to those of the PREDIMED parent study. Dietary intakes of choline and betaine were estimated from the FFQ. RESULTS: The greatest 1-y increase in dietary choline or betaine intake (quartile 4) was associated with improved serum glucose concentrations (-3.39 and -2.72 mg/dL for choline and betaine, respectively) and HbA1c levels (-0.10% for quartile 4 of either choline or betaine intake increase). Other significant changes associated with the greatest increase in choline or betaine intake were reduced body weight (-2.93 and -2.78 kg, respectively), BMI (-1.05 and -0.99, respectively), waist circumference (-3.37 and -3.26 cm, respectively), total cholesterol (-4.74 and -4.52 mg/dL, respectively), and LDL cholesterol (-4.30 and -4.16 mg/dL, respectively). Urine creatinine was reduced in quartile 4 of 1-y increase in choline or betaine intake (-5.42 and -5.74 mg/dL, respectively). CONCLUSIONS: Increases in dietary choline or betaine intakes were longitudinally related to improvements in cardiometabolic parameters. Markers of renal function were also slightly improved, and they require further investigation.This trial was registered at https://www.isrctn.com/ as ISRCTN89898870.

Factors associated with successful dietary changes in an energy-reduced Mediterranean diet intervention: a longitudinal analysis in the PREDIMED-Plus trial.

PURPOSE: Long-term nutrition trials may fail to respond to their original hypotheses if participants do not comply with the intended dietary intervention. We aimed to identify baseline factors associated with successful dietary changes towards an energy-reduced Mediterranean diet (MedDiet) in the PREDIMED-Plus randomized trial. METHODS: Longitudinal analysis of 2985 participants (Spanish overweight/obese older adults with metabolic syndrome) randomized to the active intervention arm of the PREDIMED-Plus trial. Dietary changes were assessed with a 17-item energy-reduced MedDiet questionnaire after 6 and 12 months of follow-up. Successful compliance was defined as dietary changes from baseline of ≥ 5 points for participants with baseline scores < 13 points or any increase if baseline score was ≥ 13 points. We conducted crude and adjusted multivariable logistic regression models to identify baseline factors related to compliance. RESULTS: Consistent factors independently associated with successful dietary change at both 6 and 12 months were high baseline perceived self-efficacy in modifying diet (OR6-month: 1.51, 95% CI 1.25-1.83; OR12-month: 1.66, 95% CI 1.37-2.01), higher baseline fiber intake (OR6-month: 1.62, 95% CI 1.07-2.46; OR12-month: 1.62, 95% CI 1.07-2.45), having > 3 chronic conditions (OR6-month: 0.65, 95% CI 0.53-0.79; OR12-month: 0.76, 95% CI 0.62-0.93), and suffering depression (OR6-month: 0.80, 95% CI 0.64-0.99; OR12-month: 0.71, 95% CI 0.57-0.88). CONCLUSION: Our results suggested that recruitment of individuals with high perceived self-efficacy to dietary change, and those who initially follow diets relatively richer in fiber may lead to greater changes in nutritional recommendations. Participants with multiple chronic conditions, specifically depression, should receive specific tailored interventions.

Pro-vegetarian food patterns and cardiometabolic risk in the PREDIMED-Plus study: a cross-sectional baseline analysis.

PURPOSE: We explored the cross-sectional association between the adherence to three different provegetarian (PVG) food patterns defined as general (gPVG), healthful (hPVG) and unhealthful (uPVG), and the cardiometabolic risk in adults with metabolic syndrome (MetS) of the PREDIMED-Plus randomized intervention study. METHODS: We performed a cross-sectional analysis of baseline data from 6439 participants of the PREDIMED-Plus randomized intervention study. The gPVG food pattern was built by positively scoring plant foods (vegetables/fruits/legumes/grains/potatoes/nuts/olive oil) and negatively scoring, animal foods (meat and meat products/animal fats/eggs/fish and seafood/dairy products). The hPVG and uPVG were generated from the gPVG by adding four new food groups (tea and coffee/fruit juices/sugar-sweetened beverages/sweets and desserts), splitting grains and potatoes and scoring them differently. Multivariable-adjusted robust linear regression using MM-type estimator was used to assess the association between PVG food patterns and the standardized Metabolic Syndrome score (MetS z-score), a composed index that has been previously used to ascertain the cardiometabolic risk, adjusting for potential confounders. RESULTS: A higher adherence to the gPVG and hPVG was associated with lower cardiometabolic risk in multivariable models. The regression coefficients for 5th vs. 1st quintile were - 0.16 (95% CI: - 0.33 to 0.01) for gPVG (p trend: 0.015), and - 0.23 (95% CI: - 0.41 to - 0.05) for hPVG (p trend: 0.016). In contrast, a higher adherence to the uPVG was associated with higher cardiometabolic risk, 0.21 (95% CI: 0.04 to 0.38) (p trend: 0.019). CONCLUSION: Higher adherence to gPVG and hPVG food patterns was generally associated with lower cardiovascular risk, whereas higher adherence to uPVG was associated to higher cardiovascular risk.

Phase II/III placebo-controlled randomized trial of safety and efficacy of growth hormone treatment in incomplete chronic traumatic spinal cord injury.

STUDY DESIGN: This is a double blind phase II/III placebo-controlled randomized trial of the safety and efficacy of GH treatment in incomplete chronic traumatic spinal cord injury. OBJECTIVE: The aim of this study was to investigate the possibility to use exogenous GH administration for motor recovery in chronic traumatic incomplete human SCI. The objectives were to establish safety and efficacy of a combined treatment of subcutaneous GH (or placebo) and rehabilitation in this population. SETTING: Hospital Nacional de Parapléjicos METHODS: The pharmacological treatment was a subcutaneous daily dose of growth hormone (GH, Genotonorm 0.4 mg, Pfizer Pharmaceuticals) or placebo for one year. The pharmacological treatment was performed, during the first six months under hospitalization and supervised rehabilitation. RESULTS: The main findings were that the combined treatment of GH plus rehabilitation treatment is feasible and safe, and that GH but not placebo increases the ISNCSCI motor score. On the other hand, the motor-score increment was marginal (after one-year combined treatment, the mean increment of the motor-score was around 2.5 points). Moreover, we found that intensive and long-lasting rehabilitation program per se increases the functional outcome of SCI individuals (measured using SCIM III and WISCI II). CONCLUSIONS: It is important to highlight that our aim was to propose GH as a possible treatment to improve motor functions in incomplete SCI individuals. At least with the doses we used, we think that the therapeutic effects of this approach are not clinically relevant in most subjects with SCI.

OBJETIVO: Determinar las prevalencias ajustadas por edad y sexo de concentraciones bajas de colesterol HDL (cHDL-bajo) y de dislipidemia aterogénica (DA), y valorar sus asociaciones con factores de riesgo cardiovascular, enfermedad renal crónica, enfermedades cardiovasculares y cardiometabólicas. MÉTODOS: Estudio observacional transversal de base poblacional realizado en atención primaria, con sujetos adultos seleccionados aleatoriamente. Se consideró DA si los pacientes tenían hipertrigliceridemia (triglicéridos≥150mg/dL) y cHDL-bajo (<40mg/dL [hombres],<50mg/dL [mujeres]). Se determinaron las tasas de prevalencia crudas y ajustadas por edad y sexo, y se realizó análisis univariado y multivariante para evaluar los factores cardiometabólicos relacionados. RESULTADOS: Población de estudio con 6.588 adultos (55,9% mujeres) con edad media de 55,1 (±17,5) años. Las medias de cHDL fueron 49,2 (±12,6) mg/dL en hombres y 59,2 (±14,7) mg/dL en mujeres. Las prevalencias crudas de cHDL-bajo y de DA fueron 30,8% (IC95%: 29,7-31,9), y 14,3% (IC95%: 13,5-15,2), respectivamente. Las prevalencias ajustadas de cHDL-bajo fueron 28% en hombres y 31% en mujeres, y de DA fueron 16,4% en hombres y 10,6% en mujeres. El 73% de la población con DA tenía riesgo cardiovascular alto o muy alto. Los factores independientes asociados con cHDL-bajo o con DA fueron diabetes, tabaquismo, obesidad abdominal y obesidad. Los principales factores asociados con cHDL-bajo y con DA fueron hipertrigliceridemia y diabetes, respectivamente. CONCLUSIONES: Casi un tercio de la población adulta presentaba cHDL-bajo y la mitad de ellos cumplía criterios de DA. Los factores cardiometabólicos se asociaban con cHDL-bajo y DA, destacando la hipertrigliceridemia con el cHDL-bajo, y la DM con la DA

AIM: To determine the crude and sex- and age-adjusted prevalence rates of atherogenic dyslipidemia (AD) and low HDL-cholesterol levels (low-HDLc), and to assess their associations with cardiovascular risk factors, chronic kidney disease, cardiovascular and cardiometabolic diseases. METHODS: Population-based cross-sectional study conducted in Primary Care, with randomly selected adult subjects. The AD was considered if the patients had hypertriglyceridemia (triglycerides≥150mg/dL) and low-HDLc (<40mg/dL [men];<50mg/dL [women]). Crude and sex- and age-adjusted prevalence rates were determined, and univariate and multivariate analysis were performed to assess related cardiometabolic factors. RESULTS: Study population with 6,588 adults (55.9% women) with mean age 55.1 (±17.5) years. The mean HDLc levels were 49.2 (±12.6) mg/dL in men and 59.2 (±14.7) mg/dL in women. The crude prevalence rates of low-HDLc and AD were 30.8% (95%CI: 29.7-31.9), and 14.3% (95%CI: 13.5-15.2), respectively. The adjusted prevalence rates of low-HDLc were 28.0% in men and 31.0% in women, and AD were 16.4% in men and 10.6% in women. Seventy-three percent of the population with AD had high or very high cardiovascular risk. The independent factors associated with low HDLc or with AD were diabetes, smoking, abdominal obesity, and obesity. The major factors associated with low HDLc and AD were hypertriglyceridemia and diabetes, respectively. CONCLUSIONS: Almost a third of the adult population had low HDL-C and half of them met AD criteria. Cardiometabolic factors were associated with low HDL-C and AD, highlighting hypertriglyceridemia with low HDLc, and DM with AD

Graft infusion of adipose-derived mesenchymal stromal cells to prevent rejection in experimental intestinal transplantation: A feasibility study.

BACKGROUND: Mesenchymal stromal cells (MSC) have been proposed as a promising complement to standard immunosuppression in solid organ transplantation because of their immunomodulatory properties. The present work addresses the role of adipose-derived MSC (Ad-MSC) in an experimental model of acute rejection in small bowel transplantation (SBT). MATERIAL/METHODS: Heterotopic allogeneic SBT was performed. A single dose of 1.5x106 Ad-MSC was intra-arterially delivered just before graft reperfusion. Animals were divided into CONTROL (CTRL), CONTROL+Ad-MSC (CTRL_MSC), tacrolimus (TAC), and TAC+Ad-MSC (TAC_MSC) groups. Each Ad-MSC groups was subdivided in autologous and allogeneic third-party groups. RESULTS: Rejection rate and severity were similar in MSC-treated and untreated animals. CTRL_MSC animals showed a decrease in macrophages, T-cell (CD4, CD8, and Foxp3 subsets) and B-cell counts in the graft compared with CTRL, this decrease was attenuated in TAC_MSC animals. Pro- and anti-inflammatory cytokines and some chemokines and growth factors increased in CTRL_MSC animals, especially in the allogeneic group, whereas milder changes were seen in the TAC groups. CONCLUSION: Ad-MSC did not prevent rejection when administered just before reperfusion. However, they showed immunomodulatory effects that could be relevant for a longer-term outcome. Interference between tacrolimus and the MSC effects should be addressed in further studies.

Metabolomics-guided insights on bariatric surgery versus behavioral interventions for weight loss.

OBJECTIVE: To review the metabolomic studies carried out so far to identify metabolic markers associated with surgical and dietary treatments for weight loss in subjects with obesity. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: Thirty-two studies successfully met the eligibility criteria. The metabolic adaptations shared by surgical and dietary interventions mirrored a state of starvation ketoacidosis (increase of circulating ketone bodies), an increase of acylcarnitines and fatty acid ß-oxidation, a decrease of specific amino acids including branched-chain amino acids (BCAA) and (lyso)glycerophospholipids previously associated with obesity, and adipose tissue expansion. The metabolic footprint of bariatric procedures was specifically characterized by an increase of bile acid circulating pools and a decrease of ceramide levels, a greater perioperative decline in BCAA, and the rise of circulating serine and glycine, mirroring glycemic control and inflammation improvement. In one study, 3-hydroxybutyrate was particularly identified as an early metabolic marker of long-term prognosis after surgery and proposed to increase current prognostic modalities and contribute to personalized treatment. CONCLUSIONS: Metabolomics helped in deciphering the metabolic response to weight loss treatments. Moving from association to causation is the next challenge to move to a further level of clinical application.

Lokomat robotic-assisted versus overground training within 3 to 6 months of incomplete spinal cord lesion: randomized controlled trial.

BACKGROUND: About 75% of persons with ASIA (American Spinal Injury Association) Impairment Scale C and D incomplete spinal cord injury (SCI) achieve walking ability. OBJECTIVE: To compare a walking reeducation program using Lokomat with conventional overground training among individuals with incomplete SCI of both traumatic and nontraumatic etiology. METHODS: A total of 80 participants from 3 to 6 months after onset admitted to 1 site for rehabilitation were included in a single-blind randomized clinical trial of 2 parallel groups, with blind evaluation by independent observers. Patients received 40 walking reeducation sessions of equal time using a Lokomat program with overground practice or overground mobility therapy alone. Primary measurements of outcome were walking speed and the Walking Index for Spinal Cord Injury (WISCI II). Secondary outcomes were the 6-minute walk test, locomotor section of the Functional Independence Measure, Lower Extremity Motor Score (LEMS), Ashworth Scale, and Visual Analog Scale for pain. RESULTS: No significant differences were found at entry between treatment groups. Walking speed for Lokomat (0.4m/s [0.6-0.2]) and overground therapy (0.3m/s [0.5-0.2]) groups did not differ. The WISCI II for the Lokomat group (16 [8.5-19]) was better than for overground therapy (9 [8-16]). The 6-minute walk test and LEMS displayed significant differences in favor of Lokomat therapy but were not corrected for multiple comparisons. CONCLUSIONS: Robotic-assisted training was equivalent to conventional walk training in patients with a variety of nonprogressive spinal cord pathologies for walking speed, but the need for orthotics and assistive devices was reduced, perhaps because of greater leg strength in the robotic group.

Primary mucinous neoplasms of the renal pelvis: report of two cases.

OBJECTIVE: To describe the histopathologic features and clinical presentation of two primary mucinous neoplasms of the renal pelvis. METHODS: We describe two cases and its correlation with histopathologic findings. RESULTS: Primary mucinous neoplasm of the renal pelvis was diagnosed by histopathology in two patients who received medical treatment for abdominal tumor. CONCLUSIONS: Primary mucinous neoplasms of the renal pelvis are extremely rare; the first symptom is usually abdominal growth, followed by hematuria and flank pain; it is difficult to suspect the diagnosis before surgery, because in most cases it is established with biopsy.

Modulation of human monocyte CD36 by type 2 diabetes mellitus and other atherosclerotic risk factors.

BACKGROUND: The pathophysiological role of CD36 in atherosclerosis seems to be largely dependent on its pro-inflammatory function and ability to take up oxidized low-density lipoprotein. Controversy exists concerning the potential beneficial/harmful effects of vascular CD36 inhibition in atherosclerosis. However, as atherosclerosis in murine models does not result in clinical end points such as plaque rupture and thrombotic ischaemia, typical of human disease, clinical studies are required to understand the functional role of CD36 in human atherosclerosis. MATERIALS AND METHODS: Our aim was to investigate whether CD36 expression in monocytes is modulated by the presence of an increasing number of atherosclerotic risk factors, and specifically by hyperglycaemia because of diabetes mellitus. The study included 33 patients with advanced atherosclerosis and eight healthy blood donors, as controls. The patients were classified according to the presence of atherosclerotic risk factors. Diabetes mellitus was classified as either well-controlled or poorly controlled. Monocytes were exposed in vitro to low (5·5mM) or high glucose (26mM) concentrations for increasing times. RESULTS: Our results demonstrated that protein levels of glycated CD36 were significantly higher in patients with 3-4 atherosclerotic risk factors than in those with 0-2 atherosclerotic risk factors or in subjects with no atherosclerotic symptoms (P=0·04, in both cases). However, when we analysed just the poorly controlled diabetic patients, their glycated CD36 levels were lower. These data were corroborated by in vitro studies demonstrating that increasing glucose concentrations reduced glycated protein levels (P<0·05). CONCLUSIONS: Our results demonstrate that CD36 expression is altered by hyperglycaemia in atherosclerotic patients.

Results of a sector-wide quality improvement initiative for substance-abuse care: an uncontrolled before-after study in Catalonia, Spain.

BACKGROUND: The Health Department of the Regional Government of Catalonia, Spain, issued a quality plan for substance abuse centers. The objective of this paper is to evaluate the impact of a multidimensional quality improvement initiative in the field of substance abuse care and to discuss potentials and limitations for further quality improvement. METHODS: The study uses an uncontrolled, sector-wide pre-post design. All centers providing services for persons with substance abuse issues in the Autonomous Community of Catalonia participated in this assessment. Measures of compliance were developed based on indicators reported in the literature and by broad stakeholder involvement. We compared pre-post differences in dimension-specific and overall compliance-scores using one-way ANOVA for repeated measures and the Friedman statistic. We described the spread of the data using the inter-quartile range and the Fligner-Killen statistic. Finally, we adjusted compliance scores for location and size using linear and logistic regression models. RESULTS: We performed a baseline and follow up assessment in 22 centers for substance abuse care and observed substantial and statistically significant improvements for overall compliance (pre: 60.9%; post: 79.1%) and for compliance in the dimensions 'care pathway' (pre: 66.5%; post: 83.5%) and 'organization and management' (pre: 50.5%; post: 77.2%). We observed improvements in the dimension 'environment and infrastructure' (pre: 81.8%; post: 95.5%) and in the dimension 'relations and user rights' (pre: 66.5%; post: 72.5%); however, these were not statistically significant. The regression analysis suggests that improvements in compliance are positively influenced by being located in the Barcelona region in case of the dimension 'relations and user rights'. CONCLUSION: The positive results of this quality improvement initiative are possibly associated with the successful involvement of stakeholders, the consciously constructed feedback reports on individual and sector-wide performance and the support of evidence-based guidance wherever possible. Further research should address how contextual issues shape the uptake and effectiveness of quality improvement actions and how such quality improvements can be sustained.

Assessing fatal cardiovascular disease risk with the SCORE (Systematic Coronary Risk Evaluation) scale in post-menopausal women 10 years after different hormone treatment regimens.

OBJECTIVE: To assess fatal cardiovascular disease (FCD) risk among women in early post-menopausal years, as evaluated with the Systematic Coronary Risk Evaluation (SCORE) scale. DESIGN: This was a retrospective study of parallel cohorts. Two hundred seventy-three healthy post-menopausal women. Participants received one of the following hormone treatment (HT) regimens: transdermal estradiol (50 microg) (n = 99), sequential cyclic HT with transdermal estradiol (50 microg/day) plus 200 mg/day natural micronised oral progesterone (cycle days 12-25) (n = 63) and combined HT using transdermal estradiol (50 microg) plus 100 mg/day of micronised oral progesterone (n = 61). A group of women who elected not to use HT served as control group (n = 50). SCORE values were assessed before HT or follow up. RESULTS: Only one woman displayed a high-risk SCORE value both before and after 10 years of HT, the remaining had low risk values (<5%) for FCD. After 10 years, SCORE values increased significantly as compared to baseline among HT users (all three regimens) and controls. Although post-treatment SCORE values significantly differed among groups, values were all below the high risk cut-off (5%). There were no FCD events during the 10 year observation period. CONCLUSION: As assessed with the SCORE scale, FCD risk in young post-menopausal women (HT users and controls) had a slight significant increase after 10 years, being values in the low risk range.

Pharmacokinetic interaction between rifampicin and the once-daily combination of saquinavir and low-dose ritonavir in HIV-infected patients with tuberculosis.

OBJECTIVES: To assess plasma steady-state pharmacokinetics (PK) of rifampicin, isoniazid, saquinavir and ritonavir in HIV and tuberculosis (TB) co-infected patients, and investigate potential interactions between TB drugs and protease inhibitors (PIs). METHODS: Open-label, single-arm, sequential PK study including 22 patients with HIV infection and TB. During the first 2 months, patients received rifampicin, isoniazid and pyrazinamide, with or without ethambutol (first PK study, n = 22). Then patients stopped pyrazinamide and ethambutol and started once-daily antiretroviral therapy (ART) with didanosine, lamivudine, ritonavir (200 mg) and saquinavir (1600 mg) (second PK study, n = 18). Patients stopped all TB drugs after 9 months continuing the same ART (third PK study, n = 15). Differences between TB drug parameters in the first and second PK studies, and between PI parameters in the second and third PK studies were used to assess interactions. RESULTS: Rifampicin and isoniazid pharmacokinetics did not change substantially with saquinavir and ritonavir. A significant 39.5%, 34.9% and 48.7% reduction in median saquinavir AUC(0-24), C(max) and C(trough), respectively, was seen with rifampicin and isoniazid. Ritonavir AUC(0-24), C(max) and C(trough) decreased 42.5%, 49.6% and 64.3%, respectively, with rifampicin and isoniazid. CONCLUSIONS: There was a significant interaction between saquinavir, ritonavir and rifampicin, with reduction in median plasma concentrations of saquinavir and ritonavir. Saquinavir should be given with caution in patients receiving rifampicin. Twice-daily dosing or higher saquinavir doses in once-daily administration should be tested to obtain more appropriate plasma levels.
