Bardet-Biedl syndrome (BBS) is a rare cause of renal failure requiring renal replacement therapy. It is an autosomal recessive condition characterized by retinitis pigmentosa, postaxial polydactyly, central obesity, mental retardation, hypogonadism, and renal involvement. We report the first successful renal transplant in a case of BBS from India.

BackgroundIn critically sick adults, sustained low efficiency dialysis [SLED] appears to be better tolerated hemodynamically and outcomes seem to be comparable to CRRT. However, there is paucity of data in critically sick children. In children, two recent studies from Taiwan (n = 11) and India (n = 68) showed benefits of SLED in critically sick children.Aims and objectivesThe objective of the study was to look at the feasibility and tolerability of sustained low efficiency daily dialysis-filtration [SLEDD-f] in critically sick pediatric patients.Material and methodsDesign: Retrospective study Inclusion criteria: All pediatric patients who had undergone heparin free SLEDD-f from January 2012 to October 2017. Measurements: Data collected included demographic details, vital signs, PRISM III at admission, ventilator parameters (where applicable), number of inotropes, blood gas and electrolytes before, during, and on conclusion of SLED therapy. Technical information was gathered regarding SLEDD-f prescription and complications.ResultsBetween 2012–2017, a total of 242 sessions of SLEDD-f were performed on 70 patients, out of which 40 children survived. The median age of patients in years was 12 (range 0.8–17 years), and the median weight was 39 kg (range 8.5–66 kg). The mean PRISM score at admission was 8.77±7.22. SLEDD-f sessions were well tolerated, with marked improvement in fluid status and acidosis. Premature terminations had to be done in 23 (9.5%) of the sessions. There were 21 sessions (8.6%) terminated due to hypotension and 2 sessions (0.8%) terminated due to circuit clotting. Post- SLEDD-f hypocalcemia occurred in 15 sessions (6.2%), post- SLEDD-f hypophosphatemia occurred in 1 session (0.4%), and post- SLEDD-f hypokalemia occurred in 17 sessions (7.0%).ConclusionsThis study is the largest compiled data on pediatric SLEDD-f use in critically ill patients. Our study confirms the feasibility of heparin free SLEDD-f in a larger pediatric population, and even in children weighing <20 kg on inotropic support.

ABO incompatibility has been considered as an important immunological barrier for renal transplantation. With the advent of effective preconditioning protocols, it is now possible to do renal transplants across ABO barrier. We hereby present a single center retrospective analysis of all consecutive ABOi renal transplants performed from November 2011 to August 2014. Preconditioning protocol consisted of rituximab, plasmapheresis and intravenous immunoglobulin (IVIG) and maintenance immunosuppression consisted of tacrolimus, mycophenolate sodium, and prednisolone. The outcome of these ABOi transplants was compared with all other consecutive ABO-compatible (ABOc) renal transplants performed during same time. Twenty ABOi renal transplants were performed during the study period. Anti-blood group antibody titer varied from 1:2 to 1:512. Patient and graft survival was comparable between ABOi and ABOc groups. Biopsy proven acute rejection rate was 15% in ABOi group, which was similar to ABOc group (16.29%). There were no antibody-mediated rejections in ABOi group. The infection rate was also comparable. We conclude that the short-term outcome of ABOi and ABOc transplants is comparable. ABOi transplants should be promoted in developing countries to expand the donor pool.

Acute kidney injury (AKI) is a relatively frequent problem, occurring in approximately 20 % of hospitalized patients with cirrhosis. Although serum creatinine (S Cr) is the most commonly used method to determine AKI because of easy availability and low cost, practically it underestimates the extent of kidney injury in patients with chronic liver disease. AKI is defined as an abrupt rise in S Cr of 0.3 mg/dl or more (>26.4 mmol/l) or an increase of 150 % or more (1.5-fold) from baseline. The cause of AKI in cirrhosis is multifactorial and is unique in terms of pathogenesis. The most common causes of AKI in cirrhosis can be subdivided into either functional or structural. The functional group includes volume-responsive (prerenal azotemia) and volume-unresponsive states (hepatorenal syndrome). Volume responsive is the most common type of AKI due to frequent use of diuretics, large volume abdominal paracentesis and gastrointestinal bleeding in patients with liver disease. The structural causes include acute tubular necrosis, tubulointerstitial and glomerular diseases. Patients with decompensated cirrhosis are in a vasodilatory state leading to a decrease in effective arterial blood volume, predisposing to AKI. Therefore, management of AKI depends on the underlying cause, and therapy should be directed toward removal of the cause. The outcome in cirrhosis when patients are on dialysis is very dismal. Every effort should be made to prevent AKI.
