RESUMO
The incidence of exercise-induced hematuria is reported to be between 5% and 25% and available literature suggests that it lasts for a few hours to a maximum of 3 days. We analyzed the urine sediment of healthy participants between the age of 20 and 50 years before and after a 5 km run. Anyone with abnormal pre-exercise sediment was excluded from the study. Of 491 participants, 59 (12%) developed post exercise hematuria when the run had to be completed in allotted time. However, when the run was completed without time limit, only 1.3% (4 of 316) developed hematuria (p < 0.001). We found that the younger participants (age < 30 years) had a significantly higher incidence of hematuria as compared to their older compatriots (p = 0.019). The mean duration of hematuria was 1.98 ± 1.89 days and 81% of the participants cleared their hematuria within 3 days. In 12% it lasted between 3 and 7 days and in 7% it continued beyond 7 days. Three individuals had persistence of hematuria beyond day 14 and all these were found to have primary glomerular disease on renal biopsy [two had IgA nephropathy and one focal segmental glomerulosclerosis (FSGS)]. We conclude that exercise-induced hematuria can last up to a fortnight. However, if it persists beyond a fortnight, it is unlikely to be functional and an underlying cause is likely. Hematuria following exercise seems to be related to the intensity of effort during exercise rather than its duration.

INTRODUCTION: Chronic kidney disease (CKD) is associated with significant morbidity and mortality. Screening and detection of early stages of CKD can help institute interventions that may delay the progression of the disease. One aim was to study the prevalence of early stages of CKD in the Army. METHODS: A cross-sectional study of Army Personnel in an Army cantt in Central India was carried out. All participants filled a structured questionnaire and anthropometric data was collected. Investigative profile included routine urine exam, semi-quantitative microalbuminuria (MAU), serum creatinine, lipid profile and fasting blood glucose. Glomerular Filteration rate (eGFR) was calculated using the Modification of Diet in Renal Diseases (MDRD) study equation. RESULT: A total of 1920 subjects were examined with 731 (38.07%) from Arms and 1189 (61.93%) from Services. 348 were excluded and of the remaining 1572 subjects, 141 (8.97 %) had MAU and 157 (9.99 %) had deranged Albumin Creatinine Ratio (ACR). Mean eGFR by MDRD equation was 102 ± 25.84 ml/min/1.73m (2) . Early CKD was seen in 150 (9.54 %) with 84 (5.34 %) in stage I CKD, 55 (3.5%) in stage II and 11 (0.7%) in stage III. Multiple logistic regression showed BMI > 23, the presence of DM and HTN were independent risk factors for CKD. CONCLUSION: 9.54% of healthy army personnel were found to have early stages of CKD. Institution of screening programs can result in early detection of CKD.
RESUMO
BACKGROUND: BK polyoma viral nephropathy (BKVAN) has emerged as a significant cause of renal allograft loss. The literature on BK viral infection from India is scarce. The study was therefore undertaken to evaluate impact of BK polyoma viral (BKV) infection on renal allograft recipients in Indian scenario from a service renal transplantation centre. METHODS: Renal allograft recipients who underwent graft biopsy formed the part of this descriptive cross-sectional study group. The clinicopathological profile of the patients was analysed. The diagnostic modalities employed were histopathology, immunohistochemistry using antibody for Simian virus 40 large T antigen along with real time quantification of the BK viral DNA load in the urine and the serum. RESULTS: One hundred forty seven renal allograft recipients were evaluated. 73.47 percent (108/147) patients presented with graft dysfunction and rest were protocol biopsies. There were 53 cases of rejection related diagnosis, 8 cases of graft pyelonephritis, 64 cases showed normal histology and rest exhibited miscellaneous causes. Nineteen percent (28/147) cases were positive for BKV DNA (viruria 26/147, 17.6% and viraemia 8/147, 5.44%. 3.4 percent (5/147) exhibited histological and immunohistochemical evidence of BKVAN. Nuclear enlargement, smudging and intranuclear inclusions along with plasma cell rich interstitial nephritis were important features observed on histopathology. Concomitant acute rejection was seen in 4/5 cases of BKVAN. All cases of BKVAN exhibited viraemia (> 2500 copies/mL), though cut-off values could not be defined statistically due to small sample size. Positive statistical correlation was observed between use of anti-thymocyte globulin (induction therapy and/or treatment of steroid resistant rejection, Pearson ×(2) value 6.9, P=0.008) and rejection episodes (Pearson ×(2) value 9.8, P = 0.007) with BKV infection. CONCLUSION: BK polyoma nephropathy should be added to the list of differential diagnosis considered for a renal allograft dysfunction. Renal biopsy remains the gold standard for diagnosis supplemented by non-invasive molecular techniques for screening and monitoring of BKV infection.

BACKGROUND: Renal transplantation is the treatment modality of choice for patients with end stage kidney failure. We present our experience of graft and patient survival of initial 500 renal transplants performed between May 1991 and July 2006, at Army Hospital (R&R). MATERIAL AND METHODS: All patients received triple drug immunosuppression with cyclosporine/tacrolimus, azathioprine/ mycophenolate mofetil and steroids. Patients in high risk group received induction therapy with IL-2 receptor blockers/anti-thymocyte globulin. RESULTS: Majority of the recipients (79%) were males, whereas majority of the donors (59.4%) were females. In the donor profile, 385 (77%) transplants were live related, 108 (21.6 %) were spousal and 7 (1.4%) were cadaveric transplants. Mean age of the donors and recipients was 42.11 ± 11.53 years (range 19-72 years) and 33 ± 9.39 years (range 5-60 years) respectively. Eighty two patients (16.4%) were lost to follow up and the present data on rejections, patients and graft survival pertains to 418 patients. These patients have been followed up for a mean period of 2.63 years (SE, 0.122; median 1.8 years; range 0-13.36 years). Acute rejection episodes occurred in 115 (27.3%) patients and 95% of these could be reversed with steroids/ATG. Sixty eight patients (16%) have died on follow-up. Our one-year, 5 year and 10 year estimated graft survival is 95.4% (SE, 0.01), 80.5% (SE, 0.03) and 53.1% (SE, 0.09) respectively and patient survival at one year is 93.2% (SE, 0.01). The estimated graft and patient survival in our series is 9.83 (95% CI, 8.92-10.73) and 9.80 (8.93-10.67) years respectively. CONCLUSION: This centre's short-term graft survival of 95.4% is comparable to the best centres of the world.
RESUMO
BACKGROUND: Laparoscopic donor nephrectomy (LDN) has been gaining popularity among kidney donors. There have been concerns about the safety and efficacy of the procedure as compared to open donor nephrectomy (ODN). We compare our results on LDN with ODN. METHODS: We retrospectively analysed our data of LDN and ODN. Duration of surgery, blood loss, period of hospitalisation, per oral intake and analgesic requirements. RESULT: 22 LDNs were done, the operation time ranged from 220-300 minutes, and blood loss from 100-150ml. In the first 10 laparoscopic operations four cases required conversion to open surgical dissection. Only one case was converted to open surgery in the subsequent 12 laparoscopic cases. Oral intake was started on the first postoperative day. Analgesic requirement in laparoscopy cases was less. Patients were mobilised on the first day after surgery. Patients were discharged by seventh day. There was no significant difference in the functioning of the graft after revascularisation in the recipient. CONCLUSION: Laparoscopic donor nephrectomy is a safe and effective technique of donor nephrectomy.
RESUMO
BACKGROUND: HBV DNA quantitation is used extensively world wide for the diagnosis and monitoring of treatment of Hepatitis B virus (HBV) infection. However, it has still to be popular in India. The aim of this study was to quantitate HBV - DNA by Real time - PCR method in Hepatitis B and in immuno-compromised patients, to compare the results with HBeAg detection and to monitor the response to therapy of chronic Hepatitis B patients to antivirals. METHODS: Ninety one serum samples of Hepatitis group of patients (all HBsAg positive), 41 samples from immuno-compromised patients (all HBsAg negative) and 49 patients of Chronic Hepatitis B group (all HBsAg positive) were the subjects of this first ever study in Armed Forces. Twenty serum samples from healthy volunteers and non-hepatitis B patients served as negative controls. The amplification detection was carried out in a Rotor-Gene 2000-sequence detector. RESULTS: Amongst Hepatitis B group, 33% (30/91) of the samples were positive for HBV-DNA and 26% (24/91) of samples were positive for HBeAg. In the immuno-compromised group of patients 14.6% (6/11) of samples were positive for HIV-DNA and 9.7% (4/41) were positive for HBeAg. Of the Chronic Hepatitis B patients on treatment, all (100%) were positive by HBV-DNA, whereas 29/49 (59.2%) were positive by HBeAg before treatment. After treatment with antivirals, 06/49 (12.2%) were positive by both tests and 11/49 (22.5%) were positive only by HBV-DNA. 32/49 (65.3%) patients became negative serologically after therapy. CONCLUSION: HBeAg status did not necessarily reflect HBV-DNA level in the serum, as 10/91 (11%) in the Hepatitis B group, 2/41 (4.9%) in the immuno compromised group and 20/49 (40.8%) patients in the Chronic Hepatitis B group were positive for HBV-DNA but negative for HBeAg. HBV-DNA was not found to be positive amongst any of the negative controls. Real time - PCR is a sensitive and reproducible assay for HBV-DNA quantitation and may be started in Armed Forces referral centers in the near future.
RESUMO
BACKGROUND: 170 million people are infected with the Hepatitis C virus (HCV) around the world. Approximately 50%-70% patients infected with HCV develop chronic liver disease. Haemodialysis patients constitute an especially important group with high HCV prevalence. Outbreaks of HCV infection in dialysis units have been documented. Detection of anti-HCV antibodies is a convenient and conventional mode of documentation. However, in this group, it has it's own caveats. METHODS: 48 patients who had undergone or were on haemodialysis (HD) and had undergone a minimum of 15 dialysis sittings were studied. HCV infection was documented both by anti-HCV antibody detection and HCV RNA testing. A comparative evaluation of results by both tests was done. RESULTS: Out of a total of 48 patients, HCV RNA was detected in 38 (79.16%) and anti-HCV antibodies in 13(27.07%). Out of 48 patients 10(20.83%) were negative for both parameters. 22.91% (11/48) of patients were positive for both HCV RNA and anti-HCV antibody. 56.25% (27/48) were HCV RNA positive but anti-HCV antibodies were not detectable in their sera. 2 patients (04.16%) had a positive anti-HCV antibody status despite HCV RNA being negative. In 20.83% (10/48) both parameters were undetectable. CONCLUSION: Chronic liver disease (CLD), particularly due to HCV infection, is a major complication amongst haemodialysis (HD) patients. Without reliable assays for antigenemia and the inability of antibody tests to define viremia in all cases, the detection of viral nucleic acid is necessary for diagnosis of active HCV infection.
RESUMO
This single-center study was carried out on living related and unrelated renal transplant recipients (RTRs) to evaluate the usefulness of surveillance biopsies in monitoring stable renal allografts using immuno-histological markers for immune-activation. This is a prospective, longitudinal study. Protocol biopsies of 60 RTRs with stable graft function were evaluated at three, six and 12 months post-transplant. Immuno-histological evaluation was carried out using immune-activation markers (perforins, granzyme and interleukin-2R), phenotypic markers (CD-3 and CD-20), viral markers and C4d. The demographic and clinical profile was recorded for each patient. All cases of acute sub-clinical rejection (SCR) were treated and borderline SCR cases were followed-up without treatment. SCR at three and six months post-transplant was evident in 16.7% and 3.7% of RTRs, respectively. Positive statistical association of SCR was seen with HLA-DR mismatches, whereas patients receiving induction therapy and tacrolimus-based immunosuppression exhibited a lower incidence of SCR. T cell phenotype with persistent expression of immune-activation markers exhibited positive statistical association with interstitial fibrosis and tubular atrophy at 12-month follow-up biopsy. The mean creatinine levels were significantly lower in the protocol biopsy group than the non-protocol biopsy group. No significant difference was found between the mean creatinine levels of the SCR group after treatment and the non-SCR cases within the protocol biopsy group. Early treatment of sub-clinical acute rejection leads to better functional outcomes. However, persistent immune-activation is associated with chronicity and may have implications on long-term graft survival.

Tuberculosis is an important infection encountered after renal transplantation in third-world countries. Over an 8-year period, 36 cases of tuberculosis were encountered in 305 renal transplant recipients (11.8%) with grafts functioning for more than 3 months followed up at our center. The infection was limited to the thoracic cavity in 41.7% and a single extrapulmonary site in 11.1%, and it was disseminated in 27.8% cases. In 19.4% of cases, the disease appeared as pyrexia of unknown etiology and the diagnosis was confirmed by a good therapeutic response to antitubercular therapy. Tuberculosis was diagnosed within 1 year of transplantation in 58.3% of cases. There was no significant difference in the incidence of tuberculosis in patients on different immunosuppressive regimens. The Mantoux test was positive in 33.3% patients. A total of 23 patients were treated with isoniazid and rifampicin, with the addition of a third drug for the first 2 months. Treatment was continued for 9 months in 11 cases with isolated pleuropulmonary disease and for 12-15 months in the other 12 patients. The other 13 were on cyclosporine and were given isoniazid, pyrazinamide, and ethambutol for 18 months. Two patients died of fulminant disease and five more died from unrelated causes. No recurrence of disease has been noted in any of the patients after a mean follow-up of 14.6 months. We conclude that the incidence of tuberculosis in renal allograft recipients in third world countries is much higher than that seen in the western world. Most of the cases are encountered in the first posttransplant year. Tuberculosis must be considered seriously in all patients who have prolonged fever of undetermined etiology. Treatment with isoniazid and rifampicin for 9 months is adequate for patients with localized pleuropulmonary disease. In patients on cyclosporine to whom rifampicin cannot be given because of economic considerations, treatment with isoniazid, pyrazinamide, and ethambutol should be given for 18 months.

BACKGROUND: Anaemia is a cardinal feature of chronic renal failure and classically it is normochromic normocytic. Hypochromic anaemia in these patients is often attributed to iron deficiency. AIM: This study was aimed to find the contribution of aluminium in causation of anaemia in CRF patients. METHODS: Dialysis dependent patients of chronic renal failure with adequate dietary intake (> 1500 Cals/day) and no apparent source of blood loss were evaluated for type of anaemia. (During period of this study centre didn't have reverse osmosis plant for water treatment). Evaluation included upper GI endoscopy, complete hemogram, serum proteins, serum iron, total iron binding capacity, and bone marrow iron status. For aluminium evaluation serum aluminium levels were done. RESULTS: Sixty-four patients were evaluated for type of anaemia. Mean age of patients was 41.19 years (15-76 years) with male:female ratio 2.3:1. Classical normochromic picture was seen in 28.5% while rest had hypochromic picture. On bone marrow aspiration study two patients had zero iron stores while all others had normal/excessive iron stores. In 10 patients with hypochromic picture, mean serum aluminium levels were 170 micrograms/L (30-310 micrograms/L). CONCLUSIONS: This study highlights the high prevalence of hypochromic anaemia in patients with adequate dietary intake and aluminium overload in Indian CRF patients.

Infections are the commonest cause of morbidity and mortality in renal transplant recipients. In India, tuberculosis is a one such common infection in these patients and presents with protean manifestations. We report here a case of pyrexia of unknown origin (PUO) and segmental portal hypertension in a renal transplant recipient. Search for the cause of portal hypertension revealed abdominal tubercular lymphadenitis. Treatment with anti-tubercular therapy caused regression of segmental portal hypertension.

Fifteen patients of idiopathic nephrotic syndrome who failed to respond to 8 weeks of corticosteroid therapy formed the material for this study. There were 10 males and 5 females, age ranging from 4 to 56 years. Three patients had hypertension. Histological lesions were focal and segmental glomerulosclerosis (FSGS) in 8; membranous glomerulonephritis in 3; mesangial proliferative glomerulonephritis in 2 and membranoproliferative glomerulonephritis in 2 patients. Proteinuria ranged from 3.64 to 8.66 g/1.73 m2/day. Serum albumin ranged between 2.2 to 3.3 g/dl. Serum creatinine was elevated > 1.5 mg/dl in 3 cases. After discontinuing steroids, enalapril was started in a dose of 2.5 mg/day and increased by 2.5 mg/day every 3-4 days till the maximum tolerated dose but not exceeding 20 mg/day. Proteinuria, serum albumin and serum creatinine estimations were done every 4 weeks for six months and every three months thereafter. Patients were followed up for 6 to 30 months. Proteinuria decreased to < 1.5 g/1.73 m2/day in 12 patients (80%) and to < 0.5 g/1.73 m2/day in 10 patients (66.7%) by 8 weeks. There was no significant decrease in proteinuria in 3 (20%) patients; two of these were cases of FSGS and one of membranoproliferative glomerulonephritis. Oedema, hypoalbuminaemia and hypercholesterolaemia returned to normal in all patients who had a decrease in the proteinuria. There was no correlation between the histological lesion and response to enalapril. There was no rise in the serum creatinine level above the baseline in any of the patients. Except for cough in one patient, no other significant side effects were observed. We conclude that enalapril is effective in reducing proteinuria and thereby the morbidity in steroid resistant nephrotic syndrome irrespective of the underlying pathology.

A case of invasive pulmonary aspergillosis and nocardiosis following high dose prolonged steroid therapy given for suspected rapidly progressive glomerulonephritis is reported. A favourable response was achieved with a combination of amphotericin B and cotrimoxazole. A high index of suspicion and aggressive investigations are necessary for confirmation of diagnosis and early institution of appropriate therapy.

BACKGROUND: A variety of renal lesions have been reported in HIV positive patients from western world however there is paucity of Indian data. METHODS: Over a four year period, all hospitalised HIV positive patients were screened for renal involvement. Screening was done with urinalysis. Those with abnormality in urine examination underwent further assessment with clinical, biochemical, immunological profile and renal biopsy. Renal histology was studied by light and electron microscopy. RESULTS: Twenty-five (17.6%) of the 142 patients screened, had proteinuria/abnormal urinary sediment however none of the patient had proteinuria in nephrotic range. Fourteen of these 25 patients were asymptomatic while others had AIDS. Renal biopsy was studied by light microscopy in all and by electron microscopy in 11 cases. On histology mesangioproliferative GN was encountered in eight, focal segmental glomerulosclerosis in four and collapsing GN in one patient. In two cases cryptococcal infiltration and in one lymphomatous deposits were seen in glomerulus and interstitium. In one patient interstitium showed granulomas and in other three mononuclear cell infiltration. Histology was normal in 8 (32%) patients. On EM visceral cell hyperplasia and vacuolisation was seen in all, two had collapse of glomerular basement membrane and in three cases tubuloreticular structures were seen. There was no co-relation of renal histology with duration or severity of the disease (p > 0.05). No deterioration of renal function was seen over a short follow up period of 4.2 months (1-20 months). CONCLUSION: This study highlights that HIV patients exhibiting abnormal urinary sediment usually have underlying renal lesion and at times unexpected opportunistic infections may be present.

Chronic renal failure means progressive and irreversible destruction of nephrons involving almost every organ system of the body. Early diagnosis of the disease and conservative therapy can slow down progression towards end stage renal disease. Nocturia/polyuria, anaemia, hypertension, osteodystrophy, reduced kidney size and associated acute renal failure are features which help physician in an early diagnosis. Detailed evaluation of these features has been suggested.
