EULAR 2009: Intravenous Cyclophosphamide Superior to Oral Cyclophosphamide as Induction Therapy in Lupus Nephritis Alice Goodman
"Real-life" studies in patients with lupus nephritis show that intravenous (IV) cyclophosphamide is superior to oral cyclophosphamide as induction therapy and that patients with end-stage renal disease (ESRD) can be safely managed with kidney transplantation.
"Almost Half of Those Over 60 Die While Waiting for Kidney Transplant"
These are the conclusions of 2 separate single-center studies presented here at EULAR 2009: The Annual European Congress of Rheumatology.
In a retrospective single-center study of patients with diffuse proliferative lupus nephritis, IV cyclophosphamide was superior to oral cyclophosphamide as induction therapy.
"Our results show that IV in cyclophosphamide as induction therapy is highly beneficial in Caucasian patients, compared with oral cyclophosphamide," said lead presenter M. Ramos-Casals, MD, from the Hospital Clinic in Barcelona, Spain. "These results are similar to those in Caucasian European patients, but in contrast with studies in North American and Asian patients."
Dose, Length of Cyclophosphamide Should Be Customized
Dr. Ramos-Casals said that the dose and length of cyclophosphamide needs to be individualized according to the patient's age, sex, and ethnicity.
She explained that the response to oral cyclophosphamide in this study is different from what has been reported in the literature, which she attributed to the introduction of newer medications, such as mycophenolate, that have come into use.
The investigators reviewed the outcomes of 206 patients diagnosed with lupus nephropathy between 1979 and 2007. Mean age at diagnosis was 31 years, and renal biopsy showed class IV nephritis, the focus of the study, in 81 patients (39%). All patients were treated with prednisone and immunosuppressive drugs. Induction therapy with cyclophosphamide was given to 62 (83%) of the 81 patients as part of the therapeutic regimen. Thirty-four patients received IV cyclophosphamide, 13 received oral cyclophosphamide, and 15 did not complete cyclophosphamide induction therapy.
Remission of lupus nephritis, defined as normalization of serum creatinine, was achieved in 82% of patients who received IV cyclophosphamide, in 50% who received oral cyclophosphamide, and in 36% who did not complete cyclophosphamide induction therapy.
Patients treated with IV cyclophosphamide also had improved renal response, less renal failure, fewer infections, and fewer cytopenias than those treated with oral cyclophosphamide. Frequency of death was 0% in those who received IV cyclophosphamide, 13% in those who received oral cyclophosphamide, and 23% in those who did not complete cyclophosphamide induction therapy.
Kidney Transplantation an Alternative to Renal Replacement Therapy
In a separate study at the same center, 22 years of experience (1986 to 2008) showed that kidney transplantation was a good alternative to renal replacement therapy in systemic lupus erythematosus (SLE) patients with kidney failure due to lupus nephritis.
"In our series, we had similar rates of graft failure and survival as reported with end-stage renal disease in other populations," said Gerald Espinosa, MD, from the Hospital Clinic in Barcelona.
Two factors were associated with graft rejection: antiphospholipid antibodies (APS) and hepatitis C virus (HCV) infection. "Both of these are treatable conditions. Anticoagulation is recommended for these patients, but some reports have related anticoagulation to hemorrhagic complications, so the management of these patients is difficult," he stated.
Forty kidney transplantations were performed in 29 patients between January 1986 and December 2008. Twenty patients had a single transplant, 22 (76%) had class IV lupus nephritis, and 83% were female.
Eleven cases of graft failure were reported (6 of 9 who were HCV- positive and 5 of 20 who were HCV-negative). APS antibodies were present in 76% of graft rejections and in 17% of functional grafts. Nine patients had retransplantations; 13 of the grafts deteriorated and those patients went on to dialysis (7 were HCV-positive). Two of these patients died.
"Cyclophosphamide Works"
"The clear message is that intravenous cyclophosphamide works and still should be considered effective. The other message is that if therapy for renal lupus doesn't prevent renal failure, patients can survive with a kidney transplant. Lupus [patients are] not different from nonlupus patients with ESRD — they can be transplanted," said Martin Aringer, MD, from the University of Dresden in Germany, who chaired the SLE session where these 2 presentations were given.
Dr. Ramos-Casals, Dr. Espinosa, and Dr. Aringer have disclosed no relevant financial relationships.

"Inhibitory effect of dexamethasone on in vivo erythropoiesis"
"Erythropoietic depression was elicited by cyclophosphamide administration"
It's curious how these VERY popular drugs .. reduce blood cell count. Reduce the number of red blood cells. Somewhat like .. bloodletting.
Enhanced hypoxia-stimulated erythropoietin production in mice with depression of erythropoiesis induced by hyperoxia. High Alt Med Biol. 2003 Spring;4(1):73-9. Bozzini CE, Barceló AC, Conti MI, Martínez MP, Alippi RM. Department of Physiology, Faculty of Odontology, University of Buenos Aires, Argentina. ceb...@fisio.odon.uba.ar
Current evidence suggests that a modulatory action on O(2)-dependent EPO secretion is exerted by the erythroid/precursor cell population in the erythropoietic organs through a negative feedback system. The hypothesis is based on studies of stimulated-EPO secretion performed in mice in whom the erythropoietic rates were either enhanced or depressed in the presence of normal plasma EPO half- lives. Since erythropoietic depression was elicited by cyclophosphamide administration, which could have altered EPO production directly, the aim of the present investigation was to estimate hypoxia-stimulated EPO secretion in a mouse model of functional depressed erythropoiesis induced by exposure to normobaric hyperoxia. Females CF#1 mice aged 70 d were divided into control (C) and experimental (E) groups. The former was maintained in plastic cages in a normal environment, while the latter was placed in an environment of 60% O(2)/40% N(2) in an 85-dm(3) atmospheric chamber with air flow of 1 L/min. Erythropoiesis was evaluated by either 24-h RBC-(59)Fe uptake or iron kinetics performed 3 h after IV injection of a tracer dose of (59)Fe. Both indexes of the red cell production rate were significantly depressed in E mice. Plasma disappearance of exogenous EPO in C mice, as well as in E mice exposed to hyperoxia for 4 d, was estimated by injecting (125)I-rHuEPO intravenously. Linear regression analysis indicated that neither the differences between the slopes of both curves nor the Y-intercepts were significant. Hypobaric hypoxemia was used as stimulus for EPO production. Plasma immuno-EPO titer after a 4-h exposure to hypobaric air was 73% higher in mice with hyperoxia-induced hypoerythropoiesis than in control mice with normal erythropoiesis. Data support the concept that the rate of erythropoiesis, perhaps through the number of the erythroid progenitor/precursor cell population, modulates O(2)-dependent EPO secretion.

Almost Half of Those Over 60 Die While Waiting for Kidney Transplant By Serena Gordon HealthDay Reporter THURSDAY, June 18 (HealthDay News) -- Nearly one of every two people over the age of 60 who are hoping for a kidney transplant will die while on the waiting list, new research shows.
The study also found that other factors, such as having diabetes, being black, having certain blood types, being older than 70, or waiting for a transplant in certain areas of the country increased the odds that someone would die while waiting for a donated kidney.
"The prognosis, particularly for older patients waiting for a kidney transplant, has deteriorated rapidly over the past decade," said study author Jesse Schold, an assistant professor of medicine at the University of Florida in Gainesville.
"Wait-list times have increased, but the rate of transplant hasn't increased markedly," he explained, adding that this leaves "older candidates at a significantly greater risk, because they have a higher risk of mortality in general."
Results of the study were published in the June 18 online edition of the Clinical Journal of the American Society of Nephrology.
Schold said the findings emphasize the need for people to get on transplant waiting lists immediately. "If you know this is something you're interested in, get on a waiting list before you even start dialysis, if possible," he advised.
Dr. Robert Provenzano, chief of nephrology for St. John Hospital and Medical Center in Detroit, agreed that people should get on a waiting list as soon as possible and consider getting on the waiting list at more than one medical center to improve the odds of getting a donated kidney.
The current study looked at data from 1995 through 2007 and included 54,669 candidates who were older than 60 and on a waiting list for a kidney transplant.
Of those listed in 2006 and 2007, the researchers projected that 46% would die while on the waiting list. In 1995, that number was just 22%, according to the study. Those over 70 fared even worse, with 52% expected to die before receiving a kidney transplant.
The researchers found a wide disparity -- from 6% to 81% -- in the risk of dying while on the waiting list from region to region. The areas with the lowest death rates while on the waiting list include Alaska, Hawaii, Idaho, Montana, Oregon and Washington. Areas with the highest deaths for people over 60 while on the kidney transplant list include California, Arizona, Nevada, New Mexico and Utah.
The study also found a racial disparity, with 62% of blacks expected to die while waiting for a kidney transplant. Schold said that it can be harder for blacks to find a good matching donor under the current allocation system, and that donations tend to be lower within minority groups. But, he added, these factors are improving.
Other factors that increased the rate of death while on the transplant list included having blood type B or O, having diabetes, or already being on dialysis at the time you're put on the transplant list.
Both Schold and Provenzano said the findings highlight the need to reach out more to living donors, because the need for donated kidneys far exceeds the number of donations obtained from the deceased. Even if your loved one isn't an exact match, it's possible your doctor may be able to find a paired donation in which your willing donor gives his or her kidney to someone else, and that person's loved one gives his or her kidney to you. Recently, some medical centers have created living donor chains that have an even greater potential to increase the number of transplants.
"Be proactive in navigating the steps needed to get a transplant, and consider the center that's in your best interest. You have choices," Schold said.
Provenzano also said it's critical to "take care of yourself. Sometimes people on dialysis continue to be their own worst enemy by pushing off dialysis appointments. But, the more dialysis, the better. If you can get on night-time dialysis or home dialysis, you'll probably do significantly better."

Almost Half of Those Over 60 Die While Waiting for Kidney Transplant By Serena Gordon HealthDay Reporter THURSDAY, June 18 (HealthDay News) -- Nearly one of every two people over the age of 60 who are hoping for a kidney transplant will die while on the waiting list, new research shows.
The study also found that other factors, such as having diabetes, being black, having certain blood types, being older than 70, or waiting for a transplant in certain areas of the country increased the odds that someone would die while waiting for a donated kidney.
"The prognosis, particularly for older patients waiting for a kidney transplant, has deteriorated rapidly over the past decade," said study author Jesse Schold, an assistant professor of medicine at the University of Florida in Gainesville.
"Wait-list times have increased, but the rate of transplant hasn't increased markedly," he explained, adding that this leaves "older candidates at a significantly greater risk, because they have a higher risk of mortality in general."
Results of the study were published in the June 18 online edition of the Clinical Journal of the American Society of Nephrology.
Schold said the findings emphasize the need for people to get on transplant waiting lists immediately. "If you know this is something you're interested in, get on a waiting list before you even start dialysis, if possible," he advised.
Dr. Robert Provenzano, chief of nephrology for St. John Hospital and Medical Center in Detroit, agreed that people should get on a waiting list as soon as possible and consider getting on the waiting list at more than one medical center to improve the odds of getting a donated kidney.
The current study looked at data from 1995 through 2007 and included 54,669 candidates who were older than 60 and on a waiting list for a kidney transplant.
Of those listed in 2006 and 2007, the researchers projected that 46% would die while on the waiting list. In 1995, that number was just 22%, according to the study. Those over 70 fared even worse, with 52% expected to die before ...

"Cyclophosphamide depresses erythropoietin "
EULAR 2009: Intravenous Cyclophosphamide Superior to Oral Cyclophosphamide as Induction Therapy in Lupus Nephritis Alice Goodman
"Real-life" studies in patients with lupus nephritis show that intravenous (IV) cyclophosphamide is superior to oral cyclophosphamide as induction therapy and that patients with end-stage renal disease (ESRD) can be safely managed with kidney transplantation.
"Almost Half of Those Over 60 Die While Waiting for Kidney Transplant"
These are the conclusions of 2 separate single-center studies presented here at EULAR 2009: The Annual European Congress of Rheumatology.
In a retrospective single-center study of patients with diffuse proliferative lupus nephritis, IV cyclophosphamide was superior to oral cyclophosphamide as induction therapy.
"Our results show that IV in cyclophosphamide as induction therapy is highly beneficial in Caucasian patients, compared with oral cyclophosphamide," said lead presenter M. Ramos-Casals, MD, from the Hospital Clinic in Barcelona, Spain. "These results are similar to those in Caucasian European patients, but in contrast with studies in North American and Asian patients."
Dose, Length of Cyclophosphamide Should Be Customized
Dr. Ramos-Casals said that the dose and length of cyclophosphamide needs to be individualized according to the patient's age, sex, and ethnicity.
She explained that the response to oral cyclophosphamide in this study is different from what has been reported in the literature, which she attributed to the introduction of newer medications, such as mycophenolate, that have come into use.
The investigators reviewed the outcomes of 206 patients diagnosed with lupus nephropathy between 1979 and 2007. Mean age at diagnosis was 31 years, and renal biopsy showed class IV nephritis, the focus of the study, in 81 patients (39%). All patients were treated with prednisone and immunosuppressive drugs. Induction therapy with cyclophosphamide was given to 62 (83%) of the 81 patients as part of the therapeutic regimen. Thirty-four patients received IV cyclophosphamide, 13 received oral cyclophosphamide, and 15 did not complete cyclophosphamide induction therapy.
Remission of lupus nephritis, defined as normalization of serum creatinine, was achieved in 82% of patients who received IV cyclophosphamide, in 50% who received oral cyclophosphamide, and in 36% who did not complete cyclophosphamide induction therapy.
Patients treated with IV cyclophosphamide also had improved renal response, less renal failure, fewer infections, and fewer cytopenias than those treated with oral cyclophosphamide. Frequency of death was 0% in those who received IV cyclophosphamide, 13% in those who received oral cyclophosphamide, and 23% in those who did not complete cyclophosphamide induction therapy.

In a separate study at the same center, 22 years of experience (1986 to 2008) showed that kidney transplantation was a good alternative to renal replacement therapy in systemic lupus erythematosus (SLE) patients with kidney failure due to lupus nephritis.
"In our series, we had similar rates of graft failure and survival as reported with end-stage renal disease in other populations," said Gerald Espinosa, MD, from the Hospital Clinic in Barcelona.
Two factors were associated with graft rejection: antiphospholipid antibodies (APS) and hepatitis C virus (HCV) infection. "Both of these are treatable conditions. Anticoagulation is recommended for these patients, but some reports have related anticoagulation to hemorrhagic complications, so the management of these patients is difficult," he stated.
Forty kidney transplantations were performed in 29 patients between January 1986 and December 2008. Twenty patients had a single transplant, 22 (76%) had class IV lupus nephritis, and 83% were female.
Eleven cases of graft failure were reported (6 of 9 who were HCV- positive and 5 of 20 who were HCV-negative). APS antibodies were present in 76% of graft rejections and in 17% of functional grafts. Nine patients had retransplantations; 13 of the grafts deteriorated and those patients went on to dialysis (7 were HCV-positive). Two of these patients died.

"The clear message is that intravenous cyclophosphamide works and still should be considered effective.

Current evidence suggests that a modulatory action on O(2)-dependent EPO secretion is exerted by the erythroid/precursor cell population in the erythropoietic organs through a negative feedback system. The hypothesis is based on studies of stimulated-EPO secretion performed in mice in whom the erythropoietic rates were either enhanced or depressed in the presence of normal plasma EPO half- lives. Since erythropoietic depression was elicited by cyclophosphamide administration, which could have altered EPO production directly, the aim of the present investigation was to estimate hypoxia-stimulated EPO secretion in a mouse model of functional depressed erythropoiesis induced by exposure to normobaric hyperoxia. Females CF#1 mice aged 70 d were divided into control (C) and experimental (E) groups. The former was maintained in plastic cages in a normal environment, while the latter was placed in an environment of 60% O(2)/40% N(2) in an 85-dm(3) atmospheric chamber with air flow of 1 L/min. Erythropoiesis was evaluated by either 24-h RBC-(59)Fe uptake or iron kinetics performed 3 h after IV injection of a tracer dose of (59)Fe. Both indexes of the red cell production rate were significantly depressed in E mice. Plasma disappearance of exogenous EPO in C mice, as well as in E mice exposed to hyperoxia for 4 d, was estimated by injecting (125)I-rHuEPO intravenously. Linear regression analysis indicated that neither the differences between the slopes of both curves nor the Y-intercepts were significant. Hypobaric hypoxemia was used as stimulus for EPO production.

Of those listed in 2006 and 2007, the researchers projected that 46% would die while on the waiting list. In 1995, that number was just 22%, according to the study. Those over 70 fared even worse, with 52% expected to die before receiving a kidney transplant.
The researchers found a wide disparity -- from 6% to 81% -- in the risk of dying while on the waiting list from region to region. The areas with the lowest death rates while on the waiting list include Alaska, Hawaii, Idaho, Montana, Oregon and Washington. Areas with the highest deaths for people over 60 while on the kidney transplant list include California, Arizona, Nevada, New Mexico and Utah.
The study also found a racial disparity, with 62% of blacks expected to die while waiting for a kidney transplant. Schold said that it can be harder for blacks to find a good matching donor under the current allocation system, and that donations tend to be lower within minority groups. But, he added, these factors are improving.
Other factors that increased the rate of death while on the transplant list included having blood type B or O, having diabetes, or already being on dialysis at the time you're put on the transplant list.
Both Schold and Provenzano said the findings highlight the need to reach out more to living donors, because the need for donated kidneys far exceeds the number of donations obtained from the deceased. Even if your loved one isn't an exact match, it's possible your doctor may be able to find a paired donation in which your willing donor gives his or her kidney to someone else, and that person's loved one gives his or her kidney to you. Recently, some medical centers have created living donor chains that have an even greater potential to increase the number of transplants.
"Be proactive in navigating the steps needed to get a transplant, and consider the center that's in your best interest. You have choices," Schold said.
Provenzano also said it's critical to "take care of yourself. Sometimes people on dialysis continue to be their own worst enemy by pushing off dialysis appointments. But, the more dialysis, the better. If you can get on night-time dialysis or home dialysis, you'll probably do significantly better."

"Erythropoietic depression was elicited by cyclophosphamide administration"
It's curious how these VERY popular drugs .. reduce blood cell count. Reduce the number of red blood cells. Somewhat like .. bloodletting.
Enhanced hypoxia-stimulated erythropoietin production in mice with depression of erythropoiesis induced by hyperoxia. High Alt Med Biol. 2003 Spring;4(1):73-9.

Current evidence suggests that a modulatory action on O(2)-dependent EPO secretion is exerted by the erythroid/precursor cell population in the erythropoietic organs through a negative feedback system. The hypothesis is based on studies of stimulated-EPO secretion performed in mice in whom the erythropoietic rates were either enhanced or depressed in the presence of normal plasma EPO half- lives. Since erythropoietic depression was elicited by cyclophosphamide administration, which could have altered EPO production directly, the aim of the present investigation was to estimate hypoxia-stimulated EPO secretion in a mouse model of functional depressed erythropoiesis induced by exposure to normobaric hyperoxia. Females CF#1 mice aged 70 d were divided into control (C) and experimental (E) groups. The former was maintained in plastic cages in a normal environment, while the latter was placed in an environment of 60% O(2)/40% N(2) in an 85-dm(3) atmospheric chamber with air flow of 1 L/min. Erythropoiesis was evaluated by either 24-h RBC-(59)Fe uptake or iron kinetics performed 3 h after IV injection of a tracer dose of (59)Fe. Both indexes of the red cell production rate were significantly depressed in E mice. Plasma disappearance of exogenous EPO in C mice, as well as in E mice exposed to hyperoxia for 4 d, was estimated by injecting (125)I-rHuEPO intravenously. Linear regression analysis indicated that neither the differences between the slopes of both curves nor the Y-intercepts were significant. Hypobaric hypoxemia was used as stimulus for EPO production. Plasma immuno-EPO titer after a 4-h exposure to hypobaric air was 73% higher in mice with hyperoxia-induced hypoerythropoiesis than in control mice with normal erythropoiesis. Data support the concept that the rate of erythropoiesis, perhaps through the number of the erythroid progenitor/precursor cell population, modulates O(2)-dependent EPO secretion.

Almost Half of Those Over 60 Die While Waiting for Kidney Transplant By Serena Gordon HealthDay Reporter THURSDAY, June 18 (HealthDay News) -- Nearly one of every two people over the age of 60 who are hoping for a kidney transplant will die while on the waiting list, new research shows.
The study also found that other factors, such as having diabetes, being black, having certain blood types, being older than 70, or waiting for a transplant in certain areas of the country increased the odds that someone would die while waiting for a donated kidney.
"The prognosis, particularly for older patients waiting for a kidney transplant, has deteriorated rapidly over the past decade," said study author Jesse Schold, an assistant professor of medicine at the University of Florida in Gainesville.
"Wait-list times have increased, but the rate of transplant hasn't increased markedly," he explained, adding that this leaves "older candidates at a significantly greater risk, because they have a higher risk of mortality in general."
Results of the study were published in the June 18 online edition of the Clinical Journal of the American Society of Nephrology.
Schold said the findings emphasize the need for people to get on transplant waiting lists immediately. "If you know this is something you're interested in, get on a waiting list before you even start dialysis, if possible," he advised.
Dr. Robert Provenzano, chief of nephrology for St. John Hospital and Medical Center in Detroit, agreed that people should get on a waiting list as soon as possible and consider getting on the waiting list at more than one medical center to improve the odds of getting a donated kidney.
The current study looked at data from 1995 through 2007 and included 54,669 candidates who were older than 60 and on a waiting list for a kidney transplant.
Of those listed in 2006 and 2007, the researchers projected that 46% would die while on the waiting list. In 1995, that number was just 22%, according to the study. Those over 70 fared even worse, with 52% expected to die before receiving a kidney transplant.
The researchers found a wide disparity -- from 6% to 81% -- in the risk of dying while on the waiting list from region to region. The areas with the lowest death rates while on the waiting list include Alaska, Hawaii, Idaho, Montana, Oregon and Washington. Areas with the highest deaths for people over 60 while on the kidney transplant list include California, Arizona, Nevada, New Mexico and Utah.
The study also found a racial disparity, with 62% of blacks expected to die while waiting for a kidney transplant. Schold said that it can be harder for blacks to find a good matching donor under the current allocation system, and that donations tend to be lower within minority groups. But, he added, these factors are improving.
Other factors that increased the rate of death while on the transplant list included having blood type B or O, having diabetes, or already being on dialysis at the time you're put on the transplant list.
Both Schold and Provenzano said the findings highlight the need to reach out more to living donors, because the need for donated kidneys far exceeds the number of donations obtained from the deceased. Even if your loved one isn't an exact match, it's possible your doctor may be able to find a paired donation in which your willing donor gives his or her kidney to someone else, and that person's loved one gives his or her kidney to you. Recently, some medical centers have created living donor chains that have an even greater potential to increase the number of transplants.
"Be proactive in navigating the steps needed to get a transplant, and consider the center that's in your best interest. You have choices," Schold said.
Provenzano also said it's critical to "take care of yourself. Sometimes people on dialysis continue to be their own worst enemy by pushing off dialysis appointments. But, the more dialysis, the better. If you can get on night-time dialysis or home dialysis, you'll probably do significantly better."

Chemical lowering of red blood cells / cyclophosphamide / bloodletting.
Increased red blood cell production is found in diabetes and kidney disease. In lupus they use a drug which lowers red blood cell count and curiously with lupus TOO commonly have .. kidney disease.
Coincidence .. of .. course.
"Cyclophosphamide depresses erythropoietin "
EULAR 2009: Intravenous Cyclophosphamide Superior to Oral Cyclophosphamide as Induction Therapy in Lupus Nephritis Alice Goodman
"Real-life" studies in patients with lupus nephritis show that intravenous (IV) cyclophosphamide is superior to oral cyclophosphamide as induction therapy and that patients with end-stage renal disease (ESRD) can be safely managed with kidney transplantation.
"Almost Half of Those Over 60 Die While Waiting for Kidney Transplant"
These are the conclusions of 2 separate single-center studies presented here at EULAR 2009: The Annual European Congress of Rheumatology.
In a retrospective single-center study of patients with diffuse proliferative lupus nephritis, IV cyclophosphamide was superior to oral cyclophosphamide as induction therapy.
"Our results show that IV in cyclophosphamide as induction therapy is highly beneficial in Caucasian patients, compared with oral cyclophosphamide," said lead presenter M. Ramos-Casals, MD, from the Hospital Clinic in Barcelona, Spain. "These results are similar to those in Caucasian European patients, but in contrast with studies in North American and Asian patients."
Dose, Length of Cyclophosphamide Should Be Customized
Dr. Ramos-Casals said that the dose and length of cyclophosphamide needs to be individualized according to the patient's age, sex, and ethnicity.
She explained that the response to oral cyclophosphamide in this study is different from what has been reported in the literature, which she attributed to the introduction of newer medications, such as mycophenolate, that have come into use.
The investigators reviewed the outcomes of 206 patients diagnosed with lupus nephropathy between 1979 and 2007. Mean age at diagnosis was 31 years, and renal biopsy showed class IV nephritis, the focus of the study, in 81 patients (39%). All patients were treated with prednisone and immunosuppressive drugs. Induction therapy with cyclophosphamide was given to 62 (83%) of the 81 patients as part of the therapeutic regimen. Thirty-four patients received IV cyclophosphamide, 13 received oral cyclophosphamide, and 15 did not complete cyclophosphamide induction therapy.
Remission of lupus nephritis, defined as normalization of serum creatinine, was achieved in 82% of patients who received IV cyclophosphamide, in 50% who received oral cyclophosphamide, and in 36% who did not complete cyclophosphamide induction therapy.
Patients treated with IV cyclophosphamide also had improved renal response, less renal failure, fewer infections, and fewer cytopenias than those treated with oral cyclophosphamide. Frequency of death was 0% in those who received IV cyclophosphamide, 13% in those who received oral cyclophosphamide, and 23% in those who did not complete cyclophosphamide induction therapy.
Kidney Transplantation an Alternative to Renal Replacement Therapy
In a separate study at the same center, 22 years of experience (1986 to 2008) showed that kidney transplantation was a good alternative to renal replacement therapy in systemic lupus erythematosus (SLE) patients with kidney failure due to lupus nephritis.
"In our series, we had similar rates of graft failure and survival as reported with end-stage renal disease in other populations," said Gerald Espinosa, MD, from the Hospital Clinic in Barcelona.
Two factors were associated with graft rejection: antiphospholipid antibodies (APS) and hepatitis C virus (HCV) infection. "Both of these are treatable conditions. Anticoagulation is recommended for these patients, but some reports have related anticoagulation to hemorrhagic complications, so the management of these patients is difficult," he stated.
Forty kidney transplantations were performed in 29 patients between January 1986 and December 2008. Twenty patients had a single transplant, 22 (76%) had class IV lupus nephritis, and 83% were female.
Eleven cases of graft failure were reported (6 of 9 who were HCV- positive and 5 of 20 who were HCV-negative). APS antibodies were present in 76% of graft rejections and in 17% of functional grafts. Nine patients had retransplantations; 13 of the grafts deteriorated and those patients went on to dialysis (7 were HCV-positive). Two of these patients died.
"Cyclophosphamide Works"
"The clear message is that intravenous cyclophosphamide works and still should be considered effective. The other message is that if therapy for renal lupus doesn't prevent renal failure, patients can survive with a kidney transplant. Lupus [patients are] not different from nonlupus patients with ESRD — they can be transplanted," said Martin Aringer, MD, from the University of Dresden in Germany, who chaired the SLE session where these 2 presentations were given.
Dr. Ramos-Casals, Dr. Espinosa, and Dr. Aringer have disclosed no relevant financial relationships.
