Kidney biopsy occupies a fundamental position in the management of kidney diseases. There are very few renal pathology studies available in the literature from developing world. This study scrutinized the frequency and clinicopathological relationship of kidney biopsies done at the kidney center from 1997 to 2013 amongst pediatric patients. Kidney allograft biopsy were excluded. The specimen was examined under light microscopy and immunofluorescence while electron microscopy was not done. The study includes 423 patients, mean age was 10.48 ± 4.58 years, males 245 (57.9%) were more than females 178 (42.1%). Nephrotic syndrome 314 (74.2%) was the most common clinical presentation followed by acute nephritic syndrome 35 (8.3%) and acute renal failure 24 (5.7%). Primary glomerulonephritis (PGN) was the most common group of diseases, seen in 360 (85.1%) followed by secondary glomerulonephritis (SGN) in 27 (6.4%) and tubulointerstitial nephritis in 21 (5.0%). Among PGN, minimal change disease (MCD) was the most dominant disease, with 128 (30.3%) cases followed by focal segmental glomerulosclerosis FSGS in 109 (25.8%) and membranous glomerulonephropathy in 27 (6.4%). Lupus nephritis (LN) was the leading cause of glomerular disease in SGN followed by hemolytic uremic syndrome. In conclusion, MCD is the most common histological finding, especially in younger children and FSGS is second to it. SGN is rare, and the most common disease in this category is LN while tubulointerstitial and vascular diseases are infrequent.
Sparse or outdated studies focus on thrombotic and bleeding risk in home parenteral nutrition (HPN). 236 HPN patients followed at a single center for a total of 684 patient‐years were evaluated. Rates of venous thrombosis and major bleeding, and prevalence of vena cava syndrome are provided. Anticoagulants might reduce thrombosis risk, but population‐specific safety concerns remain. Summary BackgroundHome parenteral nutrition (HPN) is necessary for patients with intestinal failure. Recurrent catheter‐related thrombosis (CRT) is common, leading to infectious complications, pulmonary embolism, vascular access loss and intestinal transplantation. The efficacy and safety of anticoagulants are unknown in this setting and based on sparse and low‐quality observational data. ObjectivesOur aim was to estimate the incidence of thromboembolic, bleeding and anticoagulant‐related complications in HPN patients, and evaluate risk factors for first venous thrombosis (VT). MethodsThis retrospective cohort study included all adult patients followed for long‐term HPN at our center between 1986 and 2014. Primary outcomes were symptomatic objectively diagnosed VT, encompassing CRT and venous thromboembolism, and major bleeding. Secondary outcomes were vena cava syndrome and heparin‐induced thrombocytopenia or hypersensitivity. ResultsA total of 236 patients were included (median HPN duration, 17 months) and 136 received anticoagulants at HPN onset (57.6%). Overall, the annual incidence of first VT was 11.4% (95% confidence interval [95% CI], 8.6–14.7%); VT was associated with a personal history of thrombosis (adjusted hazard ratio, 2.22; 95% CI, 1.06–4.64), whereas anticoagulation seemed to account only for a mild protection (adjusted hazard ratio, 0.72; 95% CI, 0.36–1.44). The annual incidence of major bleeding was 4.3% for patients on anticoagulants vs. 1.8% for those off anticoagulants. Vena cava syndrome developed in 20.7% of patients with VT. One patient had isolated heparin‐induced thrombocytopenia (0.6%) and four had heparin hypersensitivity (2.5%). ConclusionsPatients on HPN have a significant risk of venous thrombosis, major bleeding and vena cava syndrome. Anticoagulants might reduce thrombosis risk, but population‐specific safety concerns remain.
Background.Imbalance of serum sodium in the form of hypo and hypernatremia has bad prognostic impact, and linked with increase morbidity and mortality. Covid 19 is a deadly viral infection can be complicated with either of the two state. This increases the complications associated with the covid 19 infection.Material and method.This is the observational cohort study, conducted at The Indus Hospital Karachi, from March 2020 to September 2020. All patients were divided in to three groups on the basis of their serum sodium level, and distribution of variables was observed in all these three groups. To observe the effect of dysnatremias on outcome, binary logistic regression was run and odds ratios with 95% confidence interval were obtained.Results.We included 655 patients, in which 70.7% were male, while 29.3% were female. Mean age was 54 ± 15.5 with minimum of 1 year and maximum of 95 year. Hyponatremia was more common 154(23.5%) than hypernatremia 79(12.1%) patients. Dysnatremia were common in patients of age group of 51 – 65 years (Hyponatremia 72(46.8%) hypernatremia 36(45.6%). Hyponatremia didn’t show any significant effect on the clinical manifestation, critical illness and outcome of the patients except drowsiness (p=0.022). On the other hand hypernatremia had highly significant effect on clinical manifestation, critical illness and outcome of the patients. The patients who had hypernatremia died 16.8 times more than patients with normal sodium (p= 0.001).Conclusion.Dysnatremias has profound impact on the outcome of covid patients. We found development of hypernatremia has devastating effect on patient survival.
Renal biopsy is crucial while evaluating for the diagnosis of glomerular, vascular, tubulointerstitial, and genetic diseases. It gives vital information which helps in estimating the disease prognosis, progression, and management. This is the retrospective analysis of all adult patients aged above 18 years, who underwent percutaneous renal biopsy at The Kidney Center Post Graduate Training Institute, Karachi, over a duration of 18 years, i.e., January 1, 1996, to December 2013. Renal graft biopsies and those which were inadequate were excluded from analysis. Of the1962 biopsies performed, we included 1521 biopsies in our assessment. The mean age of the population was 38 ± 15.26 years (range 18-88 years). There were 920 (60.5%) males and 601 (39.5%) females. The most common clinical indication of kidney biopsy was nephrotic syndrome, i.e., 741 (45.7%), followed by chronic kidney disease, 253 (16.6%); acute renal failure, 184; (12.1%) and rapidly progressive glomerulonephritis (GN), 124 (8.2%). Primary GN was found in the majority of the patients, 984 (64.7%), followed by secondary GN in 249 (16.4%), tubulointerstitial disease in 224 (14.7%), and vascular disease in 64 (4.2%). In primary GN, focal segmental glomerulosclerosis was the most common histopathological diagnosis in 297 (19.5%) patients, followed by MGN in 224 (14.7%), chronic GN in 98 (6.4%), crescentic GN in 93 (6.1%), minimal change disease in 87 (5.7%), membranoproliferative glomerulonephritis in 58 (3.8%), and postinfection glomerulonephritis in 53 (3.5%) patients. This study shows that focal segmental glomerulosclerosis is the most common lesion in renal biopsy in the young age group followed by membranous nephropathy. Diabetic nephropathy and chronic interstitial nephritis were dominant secondary pathological lesions in older age group, whereas lupus nephritis was the most common secondary disease in young age females.
Catheter malfunctions and infections frequently occurred in NTDLC used for HD, which culminated early removal of catheter. Early creation of PVA should be encouraged to reduce the complications in already immunocompromised patients.
Patients with diabetes may have kidney diseases other than the diabetic kidney disease. Kidney biopsy is the investigation of choice when this is suspected. This retrospective analysis included all patients known to have diabetes mellitus (DM) and who had a kidney biopsy at our center between 1998 and 2014. The aim of this study was to assess if an association exists between the clinical factors on the presence or absence of diabetic nephropathy (DNP). A total number of 206 patients were included in our study. The association between the diabetic retinopathy (DRP) and DNP was high (P = 0.001). We found that the DRP is highly specific for the presence of DNP [89.7% (78 out of 87)] whereas sensitivity of DRP for DNP was 56.3% (67 out of 119). Among other factors, only duration of DM showed a significant association (P = 0.005) (odds ratio: 1.1085 and confidence interval: 1.025-1.149) with the development of DNP. We conclude that the absence of DRP is strongly associated with the presence of nondiabetic renal disease while the presence of DRP has a low sensitivity for the presence of DNP.
