RESUMO

Introduction: Retaining doctors and dentists in remote areas of Indonesia remains a national priority of the Indonesian government. The purpose of this study was to analyze the interventions for retention of doctors and dentists in remote areas using the discrete choice experiment (DCE) approach. Materials and Methods: A DCE was conducted to investigate preferences of doctors and dentists for retention in remote areas. This research was conducted in 78 primary healthcare settings across 15 provinces in Indonesia. The conditional logit model was used to explore stated preferences for each attribute. Results: The total number of respondents was 158, including 113 doctors and 45 dentists. In general, doctors placed the highest preference on getting priority for government scholarships to facilitate retention in remote areas (OR=5.65, p<0.001). Specifically, dentists preferred security guarantees from local government (OR = 4.87, p<0.001). Both groups valued having an official residence (OR=3.6, p<0.001) as a factor for retention in remote areas. Conclusion: Scholarship, security guarantees, housing facilities, and medical facilities were the most considered factors for retaining doctors and dentists in a remote area. This study confirms the importance of a combination of interventions in maintaining doctors and dentists in remote areas. Policy options in the form of non-financial and financial intervention packages can be combined to improve their retention.

RESUMO

OBJECTIVES: Renal complications of COVID-19 are not yet well studied. We aimed to evaluate acute kidney injury prevalence among hospitalized patients with COVID-19 infection and explore its effect on patient outcomes. MATERIALS AND METHODS: We retrospectively evaluated 586 hospitalized patients with COVID-19. Of these patients, 267 (45.5%) developed acute kidney injury, as classified according to the Kidney Disease Improving Global Outcomes guidelines. We compared this group with 319 patients (54.5%) without acute kidney injury. RESULTS: Most patients in both study groups were men; mean age was 60.8 ± 14 versus 51.7 ± 16 years. Comorbid conditions that were substantially predominant among patients with acute kidney injury were diabetes mellitus (64% vs 42.9%), hypertension (72.6% vs 43.5%), and ischemic heart disease (25% vs 14.7%). Fever, cough, shortness of breath, and dehydration were the main presentations among patients with acute kidney injury, and patients in this group had greater prevalence of radiological findings concordant with COVID-19 (86.8% vs 59.8%). Sepsis, volume depletion, shock, arrhythmias, and acute respiratory distress syndrome were higher in patients with acute kidney injury. Anticoagulation (85% vs 59.2%), vasopressors, plasma infusions, antimicrobials, and steroids were more frequently used in patients with acute kidney injury. More patients with acute kidney injury had acute respiratory failure requiring mechanical ventilation (62.3% vs 32.9%), with higher overall mortality rate (63.2% vs 31.1%). CONCLUSIONS: We found more frequent prevalence of acute kidney injury associated with severe COVID-19 than shown in reports from Chinese, European, and North American cohorts. Patients with COVID-19 who developed acute kidney injury had risk factors such as hypertension and diabetes, greater need for mechanical ventilation, were males, and were older age. Mortality was high in this population, especially among older patients and those who developed Kidney Disease Improving Global Outcomes stage 3 disease.

RESUMO

To show the incidence of airway complications in ICU. Endotracheal intubation is an essential skill performed by multiple medical specialists to secure a patient's airway as well as provide oxygenation and ventilation through the oral route or nose. The goal of endotracheal intubation in the emergency setting is to secure the patient's airway and obtain first-pass success. There are many indications for endotracheal intubation, including poor respiratory drive, questionable airway patency, hypoxia, and Hypercapnia. These indications are assessed by evaluating the patient's mental status, conditions that may compromise the airway, level of consciousness, respiratory rate, respiratory acidosis, and level of oxygenation. In the setting of trauma, a Glasgow Coma Scale of 8 or less is generally an indication for intubation. There are many different complications of intubation as hoarseness of voice, dental injuries, arytenoid dislocation, laryngeal stenosis, tracheal stenosis and tracheomalacia. . 150 patients who were sat in the ICU that developed certain complications. 86 patients (57.3%) were sitting in the ICU develoed certain complications. Liver diseases were the main cause of ICU admission 34 (22.7%) patients then shock 32 (21.3%) patients. Blockage of endotracheal tube was the main ICU complications 18 (12%) patients then sinusitis 16 (10.7%) patients. Endotracheal intubation is a lifesaving procedure and its complications are significant problems in ICUs. A successful procedure of intubation avoids complications. Skilled endotracheal intubation in the ICU decreases the complications.

RESUMO

OBJECTIVES: Cystinosis is the most frequent cause of the inherited renal Fanconi syndrome and is also potentially treatable. In this study, we have reported our single-center experience of the longterm outcomes of kidney transplant in patients with cystinosis. MATERIALS AND METHODS: Pediatric patients with cystinosis (n = 17) were compared with a matched control group without cystinosis (n = 126). The 2 groups were compared with regard to demographic data, posttransplant complications, and graft and patient outcomes. RESULTS: Most patients with cystinosis were male teenagers (52.9%) with comparable mean age (12.4 ± 4.1 vs 14 ± 3.1 years) versus the group without cystinosis. The 2 study groups were comparable with regard to type of dialysis, type of donor, blood group, and pretransplant comorbidities (P > .05). Patients with cystinosis received significantly more potent induction therapy (P < 0.05), but both groups were maintained on comparable immunosuppressive regimens (mostly tacrolimus based) (P > .05). Most grafts in both groups displayed immediate graft function. The percentage of patients with cystinosis with primary graft function was significantly higher than the percentage of those patients without cystinosis who had primary graft function (P = .024); this was associated with a relatively lower baseline creatinine level, although this was not significant (P > .05). Posttransplant complications, especially posttransplant diabetes, cytomegalovirus viremia, or BK nephropathy, were comparable (P > .05). Moreover, patient and graft survival rates were similar in the 2 groups (P > .05). CONCLUSIONS: Under standard immunosuppression, renal transplant and cysteamine therapy were safe with good long-term outcomes in patients with cystinosis. Studies that can include more patients and that have longer follow-up are needed to better understand the nature of this genetic disease and to discover the best treatment options.

RESUMO

INTRODUCTION: COVID-19 is an ongoing pandemic with high morbidity and mortality and with a reported high risk of severe disease in kidney transplant recipients (KTR). AIM: We aimed to report the largest number of COVID-19-positive cases in KTR in a single center and to discuss their demographics, management, and evolution. METHODS: We enrolled all the two thousand KTR followed up in our center in Kuwait and collected the data of all COVID-19-positive KTR (104) from the start of the outbreak till the end of July 2020 and have reported the clinical features, management details, and both patient and graft outcomes. RESULTS: Out of the one hundred and four cases reported, most of them were males aged 49.3 ± 14.7 years. Eighty-two of them needed hospitalization, of which thirty-one were managed in the intensive care unit (ICU). Main comorbidities among these patients were hypertension in 64.4%, diabetes in 51%, and ischemic heart disease in 20.2%. Management strategies included anticoagulation in 56.7%, withdrawal of antimetabolites in 54.8%, calcineurin inhibitor (CNI) withdrawal in 33.7%, the addition of antibiotics in 57.7%, Tocilizumab in 8.7%, and antivirals in 16.3%. During a follow-up of 30 days, the reported number of acute kidney injury (AKI) was 28.7%, respiratory failure requiring oxygen therapy 46.2%, and overall mortality rate was 10.6% with hospital mortality of 13.4% including an ICU mortality rate of 35.5%. CONCLUSION: Better outcome of COVID-19-positive KTR in our cohort during this unremitting stage could be due to the younger age of patients and early optimized management of anticoagulation, modification of immunosuppression, and prompt treatment of secondary bacterial infections. Mild cases can successfully be managed at home without any change in immunosuppression.

RESUMO

The significance of pretransplant donor-specific antibodies (DSAs) despite negative complement-dependent lymphocytotoxicity crossmatch (CDC-XM) would be useful for clinical decision-making. Hence, we aimed to determine the impact of pretransplant DSA despite negative crossmatch on the outcome of kidney transplantation. One hundred and eleven kidney recipients were prospectively enrolled in this study after being transplanted at Hamed Al-Essa Organ Transplant Center of Kuwait between January 2011 and December 2013. Of them, 50 recipients with positive DSA at the time of transplant were subjected to desensitization (Group 1). Three local protocols were utilized; first included plasma exchange, high-dose intravenous immunoglobulin (IVIG), and rituximab; second included immunoadsorption plus RTX, and the third included high-dose IVIG and rituximab. The second group included 61 recipients with negative DSA. All recipients had negative CDC-XM and flow cytometry crossmatch at the time of transplant. Panel-reactive antibody (±DSA) levels with mean fluorescence intensity and graft function were monitored along the first 24 months for all patients. There were no statistically significant differences between the two groups regarding early posttransplant graft function, patient and graft survivals. Pretransplant DSA with negative CXM carries a minimal clinical risk with optimized immunosuppression.

RESUMO

OBJECTIVES: The prevalence of BK-induced nephritis in renal transplant recipients is estimated to be 1% to 10%; the rate of graft loss within 1 year is 30% to 65%. We conducted this study to evaluate screening of BK virus in blood and/or urine among renal transplant recipients and to assess the effects of different therapeutic modalities in renal transplant recipients with BK nephropathy. MATERIALS AND METHODS: Kidney transplant recipients were screened at the time of transplant and then at 1, 2, 3, 6, 9, 12, 18, and 24 months posttransplant. Fiftynine patients were diagnosed with BK virus viremia. Patients were divided into 2 groups according to treatment: group 1 (n = 29) received an active treatment and group 2 (n = 30) received minimized immunosuppression. RESULTS: Most patients required graft biopsies to confirm diagnosis (86.2% in group 1 vs 50% in group 2; P = .03). Both groups were comparable regarding demographic data. Initial posttransplant graft function was significantly better in group 1 (P = .017); ultimately, there was no significant difference between both groups regarding graft survival (P= .51). Fifty percent of patients had biopsy-proven acute T-cell-mediated rejection before BK virus-associated nephropathy diagnosis (significantly higher in group 1). Serum creatinine levels were significantly better in group 2 at 3, 4, and 5 years after BK nephropathy (P = .001, .017, and .003, respectively). CONCLUSIONS: The prevalence of BK nephropathy in our renal transplant recipients was 5.9% with a rate of graft loss ranging from 43% to 51%. Regular screening, less intensive immunosuppressive therapy, and early intervention by reduction of immunosuppressive medications are advisable to obtain early diagnosis and to have better outcomes of BK virus-associated nephropathy with antiviral agents.

RESUMO

OBJECTIVES: Pregnancy after kidney transplant has a high risk for maternal and fetal complications; however, it can be successful if patients are properly selected. Here, we studied outcomes and complications of pregnancies in kidney transplant recipients who received calcineurin inhibitor-based immunosuppression. MATERIALS AND METHODS: In this case control study, we reviewed patients who became pregnant between 2004 and 2017. For this analysis, each pregnancy was considered an event. We divided pregnancies into 2 groups according to calcineurin inhibitor-based maintenance immunosuppression: group 1 (49 pregnancies) received cyclosporine, and group 2 (33 pregnancies) received tacrolimus. Patients also received steroids and azathioprine. Patients had regular antenatal follow-up at the Hamed Alessa Organ Transplant Center (Kuwait) and in the maternity hospital (monthly until month 7 and then weekly until delivery). RESULTS: Of 750 female kidney transplant recipients within childbearing potential, there were 82 pregnancies (10.9%) in 49 recipients (6.5%). Seventy-eight pregnancies were planned, and 4 pregnancies occurred while women were using contraception. There was 1 triple pregnancy, 5 double, and 76 single pregnancies. Two women had preeclampsia as maternal complication, 2 had uncontrolled hypertension, and 7 developed graft dysfunction. Forty-seven women (57.3%) had caesarean section, and the remaining had vaginal deliveries. Of 89 babies, 86 were viable (1 intrauterine fetal death and 2 abortions). Eight babies were delivered prematurely with low birth weight, and 2 needed incubators. Mean serum creatinine levels were 97.9 ± 24, 109 ± 38, 100 ± 39, 120 ± 46, and 115 ± 57 µmol/L at baseline, first, second, and third trimesters, and postpartum, respectively. Twelve patients showed high panel reactive antibodies but without donor-specific antibodies. CONCLUSIONS: Posttransplant pregnancy can be successful in most renal allograft recipients, but the increased risk of fetal and maternal complications, including low birth weight, spontaneous abortus, and preeclampsia, should be considered.

RESUMO

To avoid graft rejection during pregnancy, frequent monitoring of serum drug levels is recommended. Pregnancy induces hyperfiltration in transplanted kidneys, as in native kidneys; therefore, detection of rejection can be difficult when monitoring by serum creatinine. If rejection is suspected, ultrasonographguided graft biopsy can be done; once proven, it can be treated with pulse steroids, but data are scarce regarding other agents. Here, we present a 28-year-old pregnant female patient with resistant acute rejection but with successful pregnancy outcome. Our patient had end-stage kidney disease secondary to lupus nephropathy and underwent living-donor renal transplant in May 2013 after hemodialysis support for 1 year. She received thymoglobulin as induction therapy and was maintained on prednisolone, mycophenolate mofetil, and tacrolimus. She had normal renal graft function without proteinuria. After she received counseling, she became pregnant in February 2015. In June 2015, she presented with acute graft dysfunction with serum creatinine level of 365 µmol/L. Her abdominal ultrasonography showed mild hydronephrosis and viable fetus. She received empirical pulse steroids with partial response, and her graft biopsy showed acute T-cell-mediated rejection and negative C4d. Intravenous immunoglobulins and minipulse steroids were administered but without response. After gynecologic counseling and informed consent, she received 5 doses of thymoglobulin. She was dialysis dependent until premature vaginal labor, which resulted in birth of a viable 2-kg boy. We suggest that successful pregnancy outcomes could occur with close monitoring and daily dialysis in female kidney transplant patients with resistant rejection.

RESUMO

Triplet and higher-order multiple pregnancies can carry increased fetal and maternal complications. Reports of triplet pregnancies after kidney transplant are scarce and have been associated with perinatal complications. Presence of diabetes in such cases worsens both fetal and maternal outcomes. Here, we present a triplet pregnancy in a kidney transplant recipient with diabetes. We also reviewed the literature for causes, prevalence, and outcomes in association with chronic kidney disease, kidney transplant, and diabetes mellitus. The patient, a 31-year-female who received a living-donor kidney transplant, had a first-time pregnancy 6 years after transplant. Pregnancy was complicated by gestational diabetes, preeclampsia, and miscarriage. She continued to have postpartum-impaired glucose tolerance. She became pregnant again after 6 months but required insulin therapy during her third trimester. Pregnancy was terminated by cesarean section for a viable small boy. Two years later, she had triplet pregnancy after ovulation induction with clomiphene. Glycemic control was maintained using intensive insulin therapy guided by frequent home blood glucose monitoring (HbA1c was 5.8% at 22 wk). Both gynecologic care and nephrologic care were carried out through outpatient follow-up. Pregnancy was complicated by hypertension and mild renal dysfunction without proteinuria and ended in elective premature cesarean section at 32 weeks of gestation. She had 3 male babies with low birth weights (1320, 1380, 1275 g), with the largest baby developing sepsis and requiring an intensive care unit stay and then incubator for 49 days. The other 2 required incubators for 36 days. Their weights after 22 months were 9, 16, and 11 kg. The mother is now normotensive with normal renal function and impaired glucose tolerance. Care of diabetic kidney recipients with triplet pregnancy constitutes a special challenge requiring a multispecialty skilled team to ensure the best outcome.

RESUMO

OBJECTIVES: Low-dose valganciclovir prophylaxis is still under investigation in renal transplant procedures. Our aim was to assess the cost effectiveness of 450 mg versus 900 mg valganciclovir prophylaxis in kidney transplant recipients. MATERIALS AND METHODS: In this prospective trial, 201 kidney transplant patients were randomized (1:1) to receive 450 mg/d (group 1, n = 100) or 900 mg/d (group 2, n = 101) valganciclovir prophylaxis for the first 6 months after transplant. Patients were studied for incidence of cytomegalovirus disease, leucopenia episodes, rejection episodes, and graft outcomes along with associated costs over 1 year. Costs (in US dollars) of treatment of rejection were also analyzed. RESULTS: Demographic features of the studied groups were comparable. We found that the cost of cytomegalovirus care in group 1 patients was significantly lower (by 50% at 6 months; P < .001), with less leukopenia episodes (P = .04), lower doses of granulocyte colony-stimulating factor (by 30% at 6 months; P = .03), higher doses of mycophenolate mofetil (P = .04), and less rejection episodes (P = .01) compared with group 2. In group 2, there were more episodes of cytomegalovirus infection (P = .052) and BK virus nephropathy (P = .04). Graft and patient outcomes were satisfactory in both groups. CONCLUSIONS: Low-dose valganciclovir for cytomegalovirus prophylaxis after renal transplant is safer, effective and without breakthrough infection, and less costly than using the usual dose.

RESUMO

OBJECTIVES: The idea of transplanting organs is not new, nor is the disease of obesity. Obese transplant recipients have greater risk of early death than their cohorts, which is not due to increased rejection but due to obesity-related complications, including arterial hypertension, diabetes, and delayed graft function. Here, our aim was to evaluate the effects of bariatric surgery versus lifestyle changes on outcomes of moderate to severely obese renal transplant recipients. MATERIALS AND METHODS: Twenty-two morbidly obese patients with stable graft function who underwent bariatric surgery were compared with 44 obese patients on lifestyle management (control group). Both groups were evaluated regarding graft and patient outcomes. RESULTS: The studied groups were comparable demographically. In the bariatric study group versus control group, we observed that the mean body mass index was 38.49 ± 9.1 versus 44.24 ± 6 (P = .024) at transplant and 34.34 ± 7.6 versus 44.38 ± 6.7 (P = .002) at 6 months of bariatric surgery. Both groups received a more potent induction immunosuppression, but this was significantly higher in the obese nonbariatric control group (P < .05). There were more patients with slow and delayed graft functions in the same nonbariatric group. The 2 groups were comparable regarding new-onset diabetes after transplant, total patients with diabetes, and graft outcomes (P > .05). CONCLUSIONS: Bariatric surgeries are feasible, safe pro cedures for selected obese renal transplant recipients.

RESUMO

OBJECTIVES: Prophylaxis for cytomegalovirus infection is highly recommended for kidney transplant recipients. The use of daily 900 mg valganciclovir is the usual prophylactic dose, whereas 450 mg daily is under investigation. We evaluated the outcome of using 2 different doses of valganciclovir prophylaxis for cytomegalovirus infection after kidney transplant. MATERIALS AND METHODS: We randomized kidney transplant recipients (1:1) to receive 450 mg daily valganciclovir (group 1) or 900 mg daily valganciclovir (group 2) for the first 6 months after kidney transplant. Serologically, all patients were at moderate risk for cytomegalovirus infection. Patients were studied for incidence of cytomegalovirus disease, leukopenia attacks, rejection episodes, and graft outcomes for 1 year. RESULTS: Demographic features of group 1 (98 patients) and group 2 (98 patients) were comparable. More than 50% of patients received thymoglobulin induction therapy without difference between the groups. There were more leukopenia attacks in group 2 (P = .03) requiring higher doses of granulocyte colony-stimulating factor (P = .03). Group 2 patients received lower doses of mycophenolate mofetil (P= .04) and required reduced doses of valganciclovir (P = .045). Compared with group 1, the high-dose group developed numerically more rejection episodes (P = .057) and more cytomegalovirus infections requiring full treatment (P = .17). Graft and patient outcomes were satisfactory in both groups. CONCLUSION: Six months of low-dose valganciclovir prophylaxis for intermediate-risk kidney transplant recipients was as effective as high-dose valganciclovir with a better safety profile.

RESUMO

OBJECTIVES: There is no active treatment for postrenal transplant BK virus-associated nephropathy proven to be effective so far. We assessed the effectiveness of actively treating this condition with combined leflunomide, intravenous immunoglobulin, and ciprofloxacin on long-term graft outcome compared with minimization of immunosuppressive drugs. MATERIALS AND METHODS: Kidney transplant recipients were screened for BK virus-associated nephropathy. Group 1 comprised 22 kidney trans plant recipients with twice-positive BK virus polymerase chain reaction results in urine and blood. After diagnosis was confirmed with graft biopsy, antimetabolite (mycophenolate mofetil or azathioprine) was changed to leflunomide and intravenous immunoglobulin and oral ciprofloxacin were given. Group 2 comprised 33 BK virus-associated nephropathy patients treated conventionally with reduced immunosuppressive medications. RESULTS: Fifty-five patients were treated (38 males [69%], 28 patients [50.9%] with type 2 diabetes mellitus). Mean HLA antigen mismatches were 3.65, and 28 patients (50.9%) were HLA-Cw7 negative. All patients received induction therapy, 30 patients (55.6%) received thymoglobulin, and 29 patients (52.7%) received antirejection therapy before BK virus-associated nephropathy diagnosis. Maintenance immunosuppression was prednisolone in 53 patients (96.3%), mycophenolate mofetil (2 g daily) in 52 patients (94.5%), and tacrolimus in 28 patients (50.9%). Subsequent rejection episodes occurred in 38% of patients after diagnosis. Basal mean estimated glomerular filtration rate was 52.5 ± 25.5, which was reduced significantly to 38.1 ± 27.8 mL/min/1.73 m(2) (P < .0001) at end of study but without significant differences between the groups (P = .08 and P = .17). Follow-up was 7.3 ± 4.99 years. Although no significant differences were shown in patient outcome, graft survival was significantly better in group 2 (P = .032). CONCLUSIONS: Administration of 3 different anti-BK virus agents (leflunomide, intravenous immunoglobulin, ciprofloxacin) added no benefit to longterm outcome in patients with BK virus-associated nephropathy. Reduction of immunosuppressive medications appears to be a more effective treatment.

RESUMO

Focal segmental glomerulosclerosis is a common cause of end-stage renal disease in children. Focal segmental glomerulosclerosis recurrence in renal transplants is a challenging disease, and can cause graft dysfunction and loss. Different therapies exist with varying responses, from complete remission to resistance to all modes of treatment. Abatacept was recently introduced as a treatment for primary focal segmental glomerulosclerosis in native kidneys and in recurrent disease after transplant. We present a pediatric case with immunosuppression-resistant primary NPHS2-negative focal segmental glomerulosclerosis recur-rence after renal transplant. The standard therapy for recurrent focal segmental glomerulosclerosis (rituximab, plasmapheresis, high-dose cyclosporine, and corticosteroids) was tried but failed to induce remission. Abatacept (10 mg/kg) was given at 0, 2, and 4 weeks (total, 3 doses) with no good response. We conclude that abatacept may work in patients with B7-1-positive focal segmental glomerulosclerosis recurrence and its efficacy is uncertain in disease with B7-1-negative or unknown staining status.

RESUMO

OBJECTIVES: Nephropathy from BK virus is an increasing problem in renal transplant recipients and has been correlated with newer immunosuppressive agents and the decline in acute rejection rates. We aimed to evaluate the effect of BK virus-positive kidney donors on the outcome of kidney transplant recipients after mean follow-up 21 months. MATERIALS AND METHODS: Among 18 kidney donors with BK virus in blood and urine, 5 donors were fit for donation. Clinical information was reviewed for the 5 kidney transplant recipients who received kidney allografts from these donors (mean donor age, 35 ± 3 y). RESULTS: All recipients except 1 were women (mean age, 49.4 ± 4.2 y; body weight, 68.2 ± 4 kg, followup, 21.6 ± 4 mo). All patients except 1 received antithymocyte globulin induction, and all 5 patients received steroids, tacrolimus, and mycophenolate mofetil as maintenance therapy. Ureter stenting was a routine procedure in each case. Human leukocyte antigen Cw7 was detected in 4 of 5 recipients, and the fifth case, the antigen was detected in the donor. At last follow-up, all patients were enjoying functioning grafts without recurrence of BK virus infection. CONCLUSIONS: Polyoma BK virus-positive people can be accepted safely for kidney donation, especially with a possible protective role of human leukocyte antigen Cw7.
