Comparative Study to Evaluate the Effect of Low-Protein Diet Supplementation with Taurine and N-Acetylcysteine, N-Acetylcysteine and Pyridoxamine Dihydrochloride in Preventing the Progression of Chronic Renal Failure in Patients with Non-Diabetic Kidney Disease.

Chronic Kidney Disease(CKD) has multifactorial etiology and there are lots of grey zone in understanding its complex pathophysiology. There is no silver bullet for optimal care of CKD. Oxidative stress being well understood and considered as an important common progressive factor for CKD of different etiology. Several research studies focused on reducing oxidative stress and have shown diverse outcomes. In this randomized, open-label, three arms, controlled, single center study we evaluated the role of N acetylcysteine which is a direct scavenger of free radical, in combination with taurine and pyridoxamine in retarding the progression of non-diabetic kidney disease. METHODS: 69 non-dialysis, non-diabetic patients diagnosed with chronic renal failure with GFR more than 15 ml/min/1.73m2 and less than 60ml/min/1.73m2 receiving standard of care were enrolled in the study, of which 22 were in the placebo arm, 23 treated with NT (500 mg Taurine + 150 mg NAC) arm and 24 in the NP (300mg NAC+ 50mg pyridoxamine di-hydrochloride) arm. The subjects in the treatment arm received the study drug twice a day along with low protein (0.6gm protein per Kg body weight) isocaloric diet with 25-30 Kcal/Kg/D and were evaluated monthly up to 6 months. Change in eGFR accorss 3 groups over 6 months were compared. RESULT: Mean age of the subjects was 57 ± 13 years of 56.25% were male and 43.75% were female. 69 patients completed the study. The Empirical Distribution Function (EDF) of NP group was dominant over control and NT group indicating a positive effect of NT on non-diabetic CKD at 10% level of significance. In the subgroup analysis a significant effect was observed in the cases of patients receiving NP with baseline eGFR more than 45 ml/min. The mean increase in eGFR readings over six months was 8.15 units higher in the NP group than in the control group. The two-sided p-values of the t-test, the Wilcoxon test and the Kolmogorov-Smirnov test were 0.0496, 0.0316 and 0.0354, respectively. Thus, all the three tests reject the hypothesis of identical changes in eGFR at the 5% level. In subjects with bicarbonate more than 22 mg/dl, the mean increase in eGFR over six months was 10.86 units higher in the NP group than in the control group indicating NP has a positive effect on increasing eGFR over 6 months, in patients without the presence of any metabolic acidosis. The two-sided p-vales of the t-test, the Wilcoxon test and the Kolmogorov-Smirnov test were 0.0325, 0.0205 and 0.1495, respectively. Thus, two of the three tests reject the hypothesis of identical changes in eGFR at the 5% level which clearly indicates that NP had better efficacy than other groups. CONCLUSION: N-acetyl cysteine along with pyridoxine may be a useful intervention along with a low protein diet in retarding progression of CKD in the nondiabetic population in early CKD.

Hepatitis E-Induced Acute Myocarditis in an Elderly Woman.

Hepatitis E is a common, mainly water-borne hepatotropic virus prevalent mainly in Southeast Asia, Africa, the Middle East, and Central America. In the eastern part of India epidemics of acute hepatitis E are well reported. Hepatitis E commonly presents as self-limiting acute viral hepatitis among young adults, except for some critical clinical complications during pregnancy. In epidemiological research, subclinical acute hepatitis E infection is also reported from different parts of the world, including developed nations such as the USA (predominantly in the population aged >60 years). Though primarily hepatotropic, in the literature there are reports of rare extrahepatic manifestation of acute hepatitis E. Here we present an elderly lady with acute hepatitis E who primarily presented with acute myocarditis.

Colistin-induced myasthenic syndrome in a patient with end-stage renal disease.

With resurgence of multidrug resistance (MDR) bacteria and no new novel broad-spectrum antibiotic in research pipeline, usage of older generation antibiotics, once discarded due to their toxicity profile are becoming popular again. Often these drugs are the only option left in managing MDR bacteria-related sepsis. Colistin is one of such antibiotic which is often used in recent times after decades of its avoidance due to its diverse toxicity profile. In this case report, we present a rare myasthenic syndrome like neuromuscular complication developed in a patient after receiving colistin for treatment of MDR Klebsiella-related urosepsis.

Dialysis disequilibrium leading to posterior reversible encephalopathy syndrome in chronic renal failure.

Dialysis disequilibrium syndrome is a neurological adverse effect of acute hemodialysis in advanced uremic patients. Dialysis disequilibrium has a wide spectrum of clinical manifestations starting from subtle uneasiness, confusion, to florid and complex life threatening neurological deficit. In this case study, we present a patient who developed sudden cortical blindness following hemodialysis due to posterior reversible encephalopathy, which is a rare presentation of dialysis disequilibrium syndrome.

Passenger Lymphocyte Syndrome in a Renal Transplant Recipient.

New onset anaemia within three months after renal transplantation though not very common sometimes present as diagnostic challenge to the renal physicians. Understanding the etiology is necessary for correct management and avoiding adverse graft outcome. Passenger lymphocyte syndrome (PLS) is a rare entity of immune haemolytic anaemia that sometimes occurs in recipient of minor ABO mismatched renal transplantation. In this case report we present an AB positive renal allograft recipient who received organ from an O positive donor and developed acute haemolytic anaemia and jaundice, 19 days after renal transplantation due to PLS.

Unusual presentation post renal transplant lymphocele.

Retroperitoneal lymphocele is one of the common complications following renal transplantation, and usually present with persistent lymphatic drain in immediate post transplant period or perigraft collection in post transplant routine ultrasound. In this case report, we present a renal transplant recipient who presented with acute urinary retention and right sided lower limb swelling mimicking deep vein thrombosis (DVT), due to a large lymphocele behind the bladder compressing bladder neck and common iliac vessels, approximately 2 months after renal transplant. Though lymphocele is not uncommon post transplant complication, the presentation of lymphocele after 2 months post transplant with pressure effect of this type is uncommon. In this case, pressure on common iliac vessels mimicking DVT and on bladder neck, leading to acute retention of urine and leading to hydronephrotic graft; which occurred in CNI (Cyclosporine) based regimen is extremely rare.
