Mucormycosis Presented with Facial Pain in a Renal Transplant Patient: A Case Report

1st International Transplant Network Congress -- OCT 17-21, 2018 -- Antalya, TURKEYIntroduction. Mucormycosis is a severe infection in renal transplant recipients. Here, we report a case of maxillary sinus mucormycosis in a patient who presented with a facial pain complaint. Case. A 51-year-old female patient with renal transplantation due to autosomal dominant, polycystic kidney disease and diabetic nephropathy was admitted to our hospital with facial pain and minimal edema of the left half of her face on the 8th month of transplantation. On physical examination, there was only tenderness and slight edema on the left half of the face. On the paranasal computed tomography, extensive soft tissue densities involving septations, filling the left maxillary sinus, extending to the nasal cavity, and obliterating the left osteometeal unit were observed. Because facial pain was not relieved by antibiotics and several, potent analgesic drugs on the second day, mucormycosis infection with bone involvement was suspected. A left maxillary sinus excision was performed. Microscopic examination of the debridement specimen revealed necrotic bone interspersed with fungal hyphae, and culture isolated Rhizopus oiyzae. Liposomal amphotericin B was started. The patient was on tacrolimus, prednisolone, and mycophenolate mofetil. Tacrolimus was switched to cyclosporine to regulate serum glucose levels. The left maxillary sinus was washed with liposomal amphoterin B daily and curetted with intervals. The patient started dialysis because of severe renal function loss. The patient was discharged on the 96th day of liposomal amphotericin B. Conclusion. It should be kept in mind that mucormycosis may be present in the sinuses even if there is no evidence for nasal, oral, and dental examination in renal transplant patients with facial pain

Infection by the hepatitis C virus in chronic renal failure patients undergoing hemodialysis in Mato Grosso state, central Brazil: a cohort study

BACKGROUND: Hepatitis C virus (HCV) is a significant problem for patients undergoing hemodialysis therapy. This situation has never been studied in Mato Grosso state, central Brazil. This study was conducted aiming to estimate the prevalence of the anti-HCV and the incidence of seroconversion in the main metropolitan region of the state. METHODS: 433 patients from the six hemodialysis units were interviewed and anti-HCV was tested by a third-generation enzyme immunoassay. An open cohort of patients who tested negative for anti-HCV at the entry of the study was created and seroconversions was assessed monthly. The staff responsible for the units were interviewed to assess whether the infection control measures were being followed. Logistic and Cox regression analysis were performed in order to assess risk factor to HCV. RESULTS: The entry on the study took place between January 2002 and June 2005. 73 out of 433 (16.9%, CI95%: 13.3–20.8) was found to be anti-HCV reactive. The multivariate analysis indicated as risk factors associated to anti-HCV the duration of the hemodialysis treatment, the number of transfusions received, and the unit of treatment. An open cohort of 360 patients who tested negative for anti-HCV was created, with a following average of 24 (± 15) months. Forty seroconversions were recorded corresponding to an incidence density of 4.6/1000 patient-months, ranges 0 to 30 among the units. Cox regression indicated the time of hemodialysis (RR = 2.2; CI95%: 1.1–4.6; p < 0.05) and the unit where treatment was performed (RR = 42.4; CI95%: 9.9–180.5; p < 0.05) as risk factors for seroconversion. The three units with highest anti-HCV prevalence and incidence were identified as those that more frequently failed to apply control measures. CONCLUSION: The study demonstrated high prevalence and incidence of anti-HCV in some of the hemodialysis units. Time on hemodialysis therapy was an independent factor associated to HCV. Blood transfusion was associated with anti-HCV in initial survey but was not important in incident cases. Failure of applying control meaures was more evident in units with the highest HCV prevalence and incidence. The results suggest that nosocomial transmission was the main spread factor of HCV in the studied population

The role of hemodialysis machines dedication in reducing Hepatitis C transmission in the dialysis setting in Iran: A multicenter prospective interventional study

BACKGROUND: Hepatitis C virus (HCV) infection is a significant problem among patients undergoing maintenance hemodialysis (HD). We conducted a prospective multi-center study to evaluate the effect of dialysis machine separation on the spread of HCV infection. METHODS: Twelve randomly selected dialysis centers in Tehran, Iran were randomly divided into two groups; those using dedicated machines (D) for HCV infected individuals and those using non-dedicated HD machines (ND). 593 HD cases including 51 HCV positive (RT-PCR) cases and 542 HCV negative patients were enrolled in this study. The prevalence of HCV infection in the D group was 10.1% (range: 4.6%– 13.2%) and it was 7.1% (range: 4.2%–16.8%) in the ND group. During the study conduction 5 new HCV positive cases and 169 new HCV negative cases were added. In the D group, PCR positive patients were dialyzed on dedicated machines. In the ND group all patients shared the same machines. RESULTS: In the first follow-up period, the incidence of HCV infection was 1.6% and 4.7% in the D and ND group respectively (p = 0.05). In the second follow-up period, the incidence of HCV infection was 1.3% in the D group and 5.7% in the ND group (p < 0.05). CONCLUSIONS: In this study the incidence of HCV in HD patients decreased by the use of dedicated HD machines for HCV infected patients. Additional studies may help to clarify the role of machine dedication in conjunction with application of universal precautions in reducing HCV transmission
