Association of Serum Ferritin With Severity of Disease in Real-Time Reverse Transcription-Polymerase Chain Reaction Negative COVID-19 Patients

BACKGROUND

Coronavirus disease 2019 (COVID-19) is still causing disastrous effects in various parts of the world through recurring waves. Real-time reverse transcription polymerase chain reaction (RT-PCR)-negative COVID-19 is particularly challenging as these patients are less likely to receive treatment and more likely to progress to severe disease. Thus, it is imperative to find markers that can predict the severity of disease at an early stage. The objective of the present study was to analyze the association of ferritin levels with severe disease in RT-PCR-negative COVID-19 patients.

METHODS

A prospective cross-sectional analytical study was conducted in adults with COVID-19 pneumonia with a negative RT-PCR test from October 2020 to September 2021. Hematologic, biochemical, and inflammatory parameters were investigated within 24 h of hospitalization. Demographic, clinical, and laboratory findings were compared between patients with and without severe disease.

RESULTS

A total of 220 patients were included. The mean age of the study participants was 47.3 ± 14.2 years, and 55.5% (n=122) were male. C-reactive protein, D-dimer, and ferritin levels were significantly higher in patients with severe disease (p<0.01). Receiver operating characteristic curve analyses were performed, and ferritin was found as significant predictor of severe disease (area under the curve=0.642, p<0.001).

CONCLUSION

Early analysis of ferritin can predict the severity of disease in COVID-19 patients, irrespective of the RT-PCR status.

Outcomes With Levothyroxine Treatment in Early Pregnancy With Subclinical Hypothyroidism

Introduction

Adverse pregnancy outcomes in women with subclinical hypothyroidism (SCH) are well documented, whereas data regarding the risk and benefit of levothyroxine treatment in such cases are insufficient and inconsistent. Our study aimed to evaluate the effects of levothyroxine treatment on pregnancy outcomes in these women.

Materials and methods

Healthy women with a singleton pregnancy were screened before 12 weeks of gestation for subclinical hypothyroidism using 2017 American Thyroid Association guidelines. They were treated with an initial dose of 50 mcg of levothyroxine and the dose was adjusted at six-week intervals to achieve a normal thyrotropin level. All the participants were followed up with thyroid function tests and ultrasonography till delivery. Pregnancy outcomes were compared with those of healthy pregnant women with normal thyroid function.

Results 

A total of 1058 women were screened and 5.1% (n=54) were found to have subclinical hypothyroidism, out of which 57.4% (n=31) were thyroid peroxidase antibody positive. The median gestational age at the initiation of levothyroxine treatment was nine weeks. The risks for miscarriage (odds ratio (OR): 1.284, p=0.811), gestational hypertension (OR: 1.993, p=0.365), intra-uterine growth restriction (OR: 1.688, p=0.488), low birth weight (OR: 1.591, p=0.392), and preterm birth (OR: 1.606, p=0.529) were not significantly higher in women with subclinical hypothyroidism as compared to euthyroid women. However, the risk of gestational diabetes mellitus was significantly higher in women with SCH (OR: 3.432, 95% confidence interval (95% CI): 1.115-10.562).

Conclusion

Levothyroxine therapy initiated in the first trimester of pregnancy has possible beneficial effects in subclinical hypothyroidism but with a higher risk for gestational diabetes.

Primary signet cell adenocarcinoma of bladder

Primary signet cell cancer of the urinary bladder is a relatively rare entity. Since there is no mucinous epithelium in the bladder, It is proposed that the tumor arises from metaplastic urothelium. Two thirds of the tumours are mucin secreting, in most of which the site of the deposition is either extracellular or intracellular displacing the nucleus to a peripheral crescent, giving the cells a signet ring appearance. The tumours are most often infiltrative and diffusely involving the majority of the bladder akin to its name sake in stomach. It is essential to distinguish this carcinoma from gastrointestinal metastases as different therapeutic strategies are often necessary.

Clinical evaluation of selected Yogic procedures in individuals with low back pain

The present study has been conducted to evaluate selected yogic procedures on individuals with low back pain. The understanding of back pain as one of the commonest clinical presentations during clinical practice made the path to the present study. It has also been calculated that more than three-quarters of the world's population experience back pain at some time in their lives. Twelve patients were selected and randomly divided into two groups, viz., group A yogic group and group B control group. Advice for life style and diet was given for all the patients. The effect of the therapy was assessed subjectively and objectively. Particular scores drawn for yogic group and control group were individually analyzed before and after treatment and the values were compared using standard statistical protocols. Yogic intervention revealed 79% relief in both subjective and objective parameters (i.e., 7 out of 14 parameters showed statistically highly significant P < 0.01 results, while 4 showed significant results P < 0.05). Comparative effect of yogic group and control group showed 79% relief in both subjective and objective parameters. (i.e., total 6 out of 14 parameters showed statistically highly significant (P < 0.01) results, while 5 showed significant results (P < 0.05).

An unusual case of bilateral renal enlargement due to primary renal lymphoma

Primary renal lymphoma is an uncommon variant of extranodal non-Hodgkin’s lymphoma. Manifestations are usually nonspecific hematuria, fever, flank pain, and renal insufficiency. Pathological data are scanty; few reports indicate it has a very poor prognosis. We describe a child with bilateral symmetrically palpable kidneys, low-grade pyrexia, and arthralgia. Clinically, diagnosis was missed partly due to the fact that bilateral large renal tumors commonly produce asymmetric renal swelling, renal dysfunction, and hematuria which were absent in this case and partly due to rarity of the condition. However, radiological investigations combined with renal histology helped in establishing diagnosis in the present case.

A comparative clinical trial of Chincha kshara and Kadali kshara on Amlapitta

A clinical trial was carried out on 30 patients of Amlapitta aged between 20 to 35 years with complaints of Avipaka, hrit-kanthadaha, tikta-amlodgara, utklesa, udarasula, adhmana and aruchi, who were registered from OPD and IPD of Gopabandhu Ayurveda Mahavidyalaya, Puri. They were equally divided into three groups Chincha kshara, Kadali kshara and placebo (who were administered with fresh wheat powder) for 30 days in a dose of 500 mg thrice daily with water. Investigations was done in order to exclude upper gastrointestinal tract ulcer, carcinoma in stomach, cholecystitis, carcinoma gall bladder, and heart diseases. The clinical assessments were carried out on the 30^th day by subjective and objective parameters and it was inferred that both Chincha kshara and Kadali kshara were effective and reduced the symptoms of amlapitta. Chincha kshara was found to be more effective than Kadali kshara. The study shows the effect of Chincha and Kadali kshara which led to cure in 4(40%) and 3(30%) patients respectively, and maximum improvement in 4(40%) and 5(50%) patients affected with amlapitta disease, respectively. No untoward effect was noticed due to administration of ksharas during the clinical trial period.

Acute demyelinating encephalomyelitis after anti-venom therapy in Russell's viper bite

INTRODUCTION

Russell's viper is a commonly encountered venomous snake in India. Morbidity and mortality following envenomation and the treatment thereof are frequent. We report a rarely seen complication after a treated Russell's viper bite.

CASE REPORT

A 36-year-old male farmer received 30 vials polyvalent anti-snake venom after a viper bite to his right leg. Improvement in initial hematemesis and circulatory shock was followed by acute renal failure managed with regular hemodialysis. He displayed no abnormalities on neurological examination at admission. Fourth day onwards his neurologic status started deteriorating with development of behavioral abnormalities, hemi-spatial neglect of left upper limb, paralysis of left facial nerve, left upper limb, and right lower limb. Acute disseminated encephalomyelitis was confirmed on magnetic resonance imaging (MRI) of brain with typical spectroscopic characteristics. High dose methyl prednisolone was administered and a rapid recovery followed.

CONCLUSION

Russell's viper bite followed by treatment with antivenom may be complicated by the development of immune complex mediated demyelination and development of acute disseminated encephalomyelitis. MRI spectroscopy helps in early identification of demyelination and in a definite diagnosis. Treatment with corticosteroids was associated with resolution of symptoms in this case.

Refeeding syndrome

We report a case of a fifty-year-old male who was admitted with a three month history of increasing weakness, prostration, decreasing appetite and inability to swallow. The patient was a chronic alcoholic, unemployed, and of very poor socioeconomic background. The patient was initially investigated for upper GI malignancy, Addisons disease, bulbar palsy and other endocrinopathies. Concurrent management was started for severe electrolyte abnormalities and enteral nutritional supplementation was begun. By the fourth day of feeding patient developed severe hypophosphatemia and other life-threatening features suggesting refeeding syndrome. The patient was managed for the manifestations of refeeding syndrome. A final diagnosis of chronic alcoholic malnutrition with refeeding syndrome was made. Refeeding of previously starving patients may lead to a variety of complications including sudden death.

A Prospective Randomized Study to Compare Ultrasound-Guided with Nonultrasound-Guided Double Lumen Internal Jugular Catheter Insertion as a Temporary Hemodialysis Access

Internal jugular venous catheters (IJVC) for hemodialysis are a commonly employed temporary vascular access for hemodialysis. Most hospitals still follow the use of blind technique, which uses anatomical landmarks. Even in the most experienced hands this procedure has a variable success rate. Ultrasound guidance can decrease the incidence of periprocedural complications and improve the success rate. In this randomized study we compared the procedure success rate and periprocedural complications in patients undergoing ultrasound guided vs. nonultrasound guided IJVC insertion for a temporary hemodialysis access.

METHODS

All patients subjected to insertion of an IJVC between March 2004 and June 2004 were enrolled into the study, randomized to either the blind (group A) or ultrasound guided (group B) procedure, which uses a portable ordinary ultrasound machine without a needle guide. The aseptic Saldinger technique was used for catheterization in both the groups. Baseline characteristics of patient and periprocedural events were recorded.

RESULTS

A total of 60 patients were randomized, 30 patients each in two groups. First attempt venous cannulation success rate was 56.7% in group A compared to 86.7% in group B. Chance of occurrence of adverse outcome was significantly more in the blind procedure (P=0.020). A post-procedure chest radiograph done in all patient showed no complications.

CONCLUSION

Ultrasound guided procedure for internal jugular vein catheter insertion using an ordinary ultrasound machine was significantly safer and more successful as compared to the blind technique.

Tacrolimus (Pan Graf) in Live Related Renal Transplantation: An Initial Experience of 101 Recipients in India

BACKGROUND

Success of modern transplantation is in large part due to the successful development of effective immunosuppressive agents. The safety and efficacy of tacrolimus in transplantation is well established. However, tacrolimus (Pan Graf, Panacea Biotec Ltd, India) has only been available in India for the last 2 years. This study was conducted to assess the safety and efficacy of tacrolimus in live related kidney transplantation. We report an initial experience of tacrolimus as de novo therapy in a live related renal transplantation program.

MATERIALS AND METHODS

One hundred one consecutive recipients of a live renal allograft were commenced on triple immunosuppression consisting of tacrolimus, mycophenolate mofetil or azathioprine, and steroids. The dose of tacrolimus was adjusted to keep trough levels at 10-12 ng/mL in the first 3 months, 8-10 ng/mL in the next 3 months, and 5-8 ng/mL thereafter. All patients were followed up for a period ranging from 4 weeks to 24 months. The effect of this regimen on the incidence of graft rejection, graft survival, patient survival, and new-onset diabetes mellitus was evaluated. Any evidence of graft dysfunction was evaluated using a graft biopsy.

RESULTS

There were 89 male and 12 female patients with mean age of 32.08 years. The incidence of acute rejection was 3.96%; 21.05% developed new-onset diabetes mellitus. Six patients were diabetic prior to transplantation and 9 patients were hepatitis C virus (HCV)-positive; 77.7% of HCV-positive patients and 15.1% of HCV-negative patients developed posttransplantation diabetes mellitus. The patient survival rate at the current follow-up was 92.07%. No graft was lost due to rejection.

CONCLUSION

Tacrolimus is a safe and effective immunosuppressant in live related renal transplantation.

Tacrolimus (Pan Graf) as de Novo Therapy in Renal Transplant Recpients in India

The safety and efficacy of tacrolimus in transplantation is well established. However, tacrolimus has only recently been available in India. We report an initial experience using tacrolimus as de novo therapy in a living related renal transplant program. Fifty-two consecutive recipients of living renal allografts were treated with tacrolimus, mycophenolate mofetil, or azathioprine and steroids. The dose of tacrolimus was adjusted to keep trough levels at 10 to 12 ng/mL in the first 3 months, 8 to 10 ng/mL in the next 3 months, and 5 to 8 ng/mL thereafter. Any evidence of graft dysfunction was evaluated by graft biopsy. The effect of this regimen on the lipid profile as well as the incidence of posttransplant diabetes mellitus was evaluated in an Indian population. All patients were followed for periods ranging from 6 to 72 weeks (mean = 29 weeks). The incidence of acute rejection was 3.84%; 17.3% developed posttransplant diabetes mellitus. Graft and patient survivals at the current follow-up were 100% and 96.26%. In conclusion, tacrolimus is a safe and effective immunosuppressant in a living related renal transplant program.

Significance of Protocol Biopsies in Living Related Renal Transplant Recipients

INTRODUCTION

Subclinical rejection (SCR) in a normally functioning renal allograft may have an impact on long-term graft outcome. SCR detection is best done by protocol biopsies in clinically normal grafts.

METHODS

We evaluated 20 stable living related renal allografts with protocol biopsies on days 7 and 90 posttransplant. SCR when detected was treated with a 3-day pulse of methylprednisolone therapy. The outcomes of these grafts were compared with 63 other clinically stable renal allografts that did not undergo protocol biopsies.

RESULTS

SCR was observed in 60% of cases. The patients who received antirejection therapy for SCR based on protocol biopsies showed better graft survival and mean serum creatinine values at the end of the follow-up period.

Functional assessment of immune markers of graft rejection: a comprehensive study in live-related donor renal transplantation

A better understanding of the immunobiological processes and predictors of graft rejection holds promise for the development of potential therapeutic strategies and also individualization of immunosuppression. The objective of this study is to analyze the clinical relevance of immune parameters such as antidonor antihuman leukocyte antigen (anti-HLA) antibodies, monitoring of cytokines and their receptors on the graft outcome following live-related donor renal transplantation. Flow cytometry-based methods were used to detect antidonor antibodies (flow cytometry crossmatch, FCXM) and intracellular cytokines. Enzyme-linked immunosorbent assay (ELISA) methods were employed to detect anti-HLA class I and class II antibodies and quantitative serum-soluble interleukin-2 receptor (sIL-2R) levels. The data revealed that patients with HLA class I-specific IgG antibody experienced higher acute rejection (AR) episodes at 1 yr in comparison to the antibody negative group (82% vs. 56%, p = 0.01). On the contrary, donor-specific class II antibodies (B+) did not have any influence on the graft survival. However, 15 recipients having both T- and B-cell antidonor antibodies (T+B+) had significantly poor graft survival (60%) as compared to the antibody-negative group (T-B-, 82%, p = 0.05). Additionally, patients having non-donor but HLA-specific antibodies (FCXM-/ELISA+) had poor graft survival as compared to the antibody-negative group (64% vs. 88%, p < 0.05). Further, patients undergoing AR episodes had significantly higher expression of IFN-gamma-producing T cells (19.16 +/- 7.4% median 17.50) as compared to their pre-transplant levels (5.68 +/- 1.63%, Median 5.20) and the non-rejecter group (5.97 +/- 4.39%, median 4.3, p = 0.0004). Similarly sIL-2 was significantly increased in AR episodes during the first month of transplantation (292 +/- 131.5 pmol/L) as compared to those with well-functioning grafts (p = 0.01) and healthy controls (p = 0.001). Evaluation of antidonor antibodies by flow cytometry is found to be relatively more sensitive and a better predictor of graft outcome. Further monitoring of cytokine expression profile of primed peripheral T-helper cells and quantitative analysis of sIL-2R offer additional valuable diagnostic and prognostic tools for follow-up of transplant subjects and a better alternative for functional assessment of immunosuppression.

Fibrosing cholestatic hepatitis in renal transplant recipient with CMV infection: a case report

Fibrosing cholestatic hepatitis (FCH) is an uncommon complication of renal transplantation. It is usually associated with hepatitis B and C viral infection. It is further rare in renal transplantation in absence of HBV and HCV infection. To the best of our knowledge, only three cases of FCH in renal transplantation, which were both HBV and HCV negative, have been reported to date. Out of these, two cases were diagnosed to have CMV infection and the third was attributed to azathioprin. We are presenting another case of FCH in a renal transplant recipient with CMV infection.

Prospective randomized control trial of isoniazid chemoprophylaxis during renal replacement therapy

BACKGROUND

Infectious diseases remain among the major morbid events in patients with end-stage renal disease (ESRD) on renal replacement therapy (RRT). In developing countries, tuberculosis (TB) has been found to occur more frequently in these patients than in the general population. Efficacy of isoniazid (INH) chemoprophylaxis has been seen in other situations, such as human immunodeficiency virus infection. However, studies on INH prophylaxis in ESRD patients on RRT are limited.

METHODS

In this prospective randomized controlled trial, from April 2000 to June 2001, a total of 109 ESRD patients registered for renal transplant and accepted for maintenance hemodialysis in our hospital were included and followed up until June 2004 to assess the role of INH prophylaxis in preventing development of TB. At the time of acceptance for hemodialysis, 54 patients were assigned to receive daily INH for 1 year and 55 patients were assigned to the control group. Primary outcome was development of TB. Secondary outcome was INH hepatotoxicity. To evaluate the effect of INH prophylaxis on the development of TB, a Kaplan-Meier survival estimate was used to plot TB-free survival curve and log-rank test was used for comparison.

RESULTS

Overall, TB was diagnosed in 27 patients during RRT, with an incidence of 24.8%. TB developed in 9 (16.7%) patients in the INH group and in 18 (32.7%) patients in the control group. There was a significantly lower incidence of TB in the INH group as compared with the control group. The risk ratio of INH vs. control group for development of TB was 0.40 (95% confidence index [CI], 0.17-0.92; P=0.032). In the INH group 27 (50%) patients and in the control group 17 (30.9%) patients developed some hepatic dysfunction. However, significant hepatitis that required discontinuation of INH developed in only 9 (16.7%) patients in the INH group. Furthermore, significant hepatitis also developed in 6 (10.9%) patients in the control group. The majority of patients with significant hepatitis in both groups (INH as well as control) were subsequently found to be positive for hepatitis B and/or hepatitis C viral infection. Mild hepatitis (which did not require discontinuation of INH) was seen in 18 (33.3%) patients in the INH group and 11 (20%) patients in the control group. Viral hepatitis infection was not found in any of the milder cases of hepatitis in either group.

CONCLUSION

This study shows significant efficacy of INH chemoprophylaxis during RRT in preventing development of TB, when the INH was started during dialysis itself. INH chemoprophylaxis was safe and well tolerated in the majority of patients. However, mild hepatic dysfunction was common, both in the treatment as well as in the control group. As the incidence of viral hepatitis overall was high in our patients on RRT, it is difficult to identify INH-induced hepatitis in this clinical setting.

Fibrillary Glomerulonephritis Presenting as Rapidly Progressive Renal Failure in a Young Female: A Case Report

Fibrillary Glomerulonephritis (FGN) is a rare clinical entity presenting in majority of patients with nephrotic range proteinuria, microscopic hematuria, impaired renal function and hypertension. The mean age of presentation is reported to be beyond 50 years with 50 patients developing end stage renal disease within a few years. A 28-year-old female presented to us with non-nephrotic range proteinuria, rapidly progressive renal failure (RPRF), microscopic hematuria and mild hypertension. The patient had undergone a renal biopsy at a peripheral center, which was reported as membranoproliferative glomerulonephritis (MPGN) and was being treated with steroids without any benefit. The patient on re-biopsy at our center was diagnosed as FGN on electron microscopy (EM). The patient responded to intravenous pulse methylprednislone and oral cyclophosphamide and is off dialysis for 10 months now. This case highlights the varied clinical and histological presentations of FGN which makes the disease difficult to diagnose more so, in a country like ours where EM is available in only a few centers. An accurate diagnosis aided by high index of clinical suspicion and EM can help in the initiation of appropriate therapy, thereby improving the outcome in this disease which otherwise has a poor prognosis.

Antegrade endopyelotomy in pelvic kidney

Antegrade endopyelotomy was performed in a patient with pelvic kidney. Nephrostomy tube had been placed in the patient during a previous open pyelolithotomy. The nephrostomy tract was used for establishing percutaneous access. The ureteropelvic junction (UPJ) was balloon dilated and incised laterally under vision. At 3-month-follow-up renal dynamic scan showed no evidence of UPJ obstruction.

Frequency and role of hepatitis-C virus and type II cryoglobulinemia in membranoproliferative glomerulonephritis

BACKGROUND

Many studies have claimed a major role of chronic hepatitis-C virus (HCV) infection in immune-mediated diseases such as membranoproliferative glomerulonephritis (MPGN). Chronic HCV infection is also known to produce essential mixed cryoglobulinemia (EMC), which in turn may manifest as vasculitis and cryoglobulinemic MPGN.

OBJECTIVE

The aim of the study therefore, was to determine frequency of association and pathogenetic role of HCV infection as well as that of EMC in MPGN patients.

METHODS

Fifty-three adult patients of MPGN were studied for HCV, HBsAg, EMC, C3, anti-nuclear antibody (ANA), rheumatoid factor serologically. Histopathology, immunofluorescence (IF) were conducted in all patients and electron microscopy (EM) in those who were found HCV positive. Simultaneously 37 follow-up patients of HCV associated chronic hepatitis were investigated for EMC, renal functions and urinalysis done for evidence of glomerulonephritis (GN).

RESULTS

Thirteen percent MPGN patients were HCV positive, however, no viral particle could be seen in electron microscopy in glomeruli of these patients. There was no serologic evidence of HCV induced immune complex GN. None of the MPGN patients showed cryoglobulinaemia. Similarly none from HCV associated chronic hepatitis group had EMC nor showed evidences of glumerulonephritis.

CONCLUSION

Thirteen percent of adult MPGN patients in north India were seropositive for HCV, indicating significant association. However, clear evidence in favour of its pathogenetic role was lacking in our study. Secondly, this study reveals that MPGN is non-cryoglobulinemic and HCV is not a major cause in our population compared to what is reported from other countries. These observations need confirmation by a larger study.

Prospective randomised trial of isoniazid prophylaxis in renal transplant recipient

Renal transplantation (RT) recipients are at a high risk of developing tuberculosis (TB) following transplantation. Effectiveness of isoniazid (INH) in preventing TB is well documented in immunocompetent as well as immunocompromised persons. There is paucity of data on role of INH prophylaxis in RT recipients. Thus, a prospective randomised trial of INH in RT recipients was carried out to determine the efficacy of daily INH monotherapy in the prevention of TB in these patients. Patients of end stage renal disease (ESRD) taken for RT formed the subjects of study. Patients with active TB and active hepatitis at the time of RT were excluded from the study. Patients were randomised to receive INH 300 mg with pyridoxine 20 mg daily from the day of RT. The duration of the treatment was planned for 1 year or till the development of TB, which ever was earlier. Between October 1998 and September 2000, 114 RT were done at our hospital. Of these, 24 (21%) patients had active TB at the time of RT and thus were excluded. Patients included were randomised with 1:2 ratio of treatment and control group. Of the 90 patients thus enrolled, 30 were randomised in treatment group and 60 in control group. Of the included patients five patients had very early graft loss (three in treatment and two in control group) within days and thus excluded from the analysis. Three of the 27 (11.1%) patients in treatment group and 15 (25.8%) in control group developed TB (P = 0.10). The risk ratio of (RR) of INH versus control group of TB was 0.36 (95% CI, 0.10-1.32) but the difference was not statistically significant (P = 0.12). Only one patient developed INH induced hepatitis. In conclusion, with INH prophylaxis, there was a trend towards protection from TB, though it was not statistically significant. Further, all patients tolerated INH and hepatotoxicity was not a major problem in this group of patients.

Neoral monitoring by limited sampling area under the concentration time curve in stable indian renal transplant recipients

The optimization of cyclosporine (CsA) immunosuppression remains a challenge because of the narrow therapeutic window and highly variable pharmacokinetics (PK). The highly variable PK were improved by the introduction of the current microemulsion preparation Neoral. However, the best clinical benefit of this CsA microemulsion can only be obtained by regular PK monitoring. During the past decade, various PK strategies have been proposed, such as C(0), C(2), level monitoring, abbreviated or limited sampling approach, and various prediction algorithms to replace the conventional area under the curve (AUC). In this study we evaluated the Neoral PK in stable Indian renal transplant recipients using a limited sampling approach. The C(0) (mean +/- SE) was 175 +/- 15 ng. mL(-1); C(max) 970 +/- 101 ng. mL(-1), and the AUC (0-4) 2734 +/- 258 ng. h. mL(-1). The C(0) showed a poor relationship to AUC (0-4) (r =.65) but high correlations were obtained with C(2) (r = 0.93) and C(3) (r =.96). Our finding suggest that stable Indian renal transplant recipients should either be monitored using C(2) or C(3).

A case of chronic myeloid leukemia complicated with minimal change nephrotic syndrome

We present a 28-year-old patient with chronic myeloid leukemia (CML) in chronic phase complicated with nephrotic syndrome. The bone marrow cells revealed the presence of Philadelphia chromosome, the cytogenetic hallmark of CML, that results from a balanced, reciprocal translocation between the long arms of chromosomes 9 and 22, t(9;22)(q34;q11). This reciprocal translocation leads to the formation of the BCR/ABL fusion gene, the presence of which was confirmed using the highly sensitive fluorescence in situ hybridization technique. The renal biopsy was compatible with minimal change nephrotic syndrome. To the best of our knowledge, this is the first case of minimal change nephrotic syndrome associated with CML before the administration of any therapy.

Pulmonary mucormycosis in a diabetic renal transplant patient

A 50-year-old male, diabetic, post transplant patient had recurrent pneumonia. The first episode responded well to antibiotics, while on the second occasion he had a necrotising pneumonia, which developed into a thick-walled cavity. Despite antibiotics, his condition rapidly deteriorated precluding bronchoscopy or percutaneous biopsy. Post-mortem lung biopsy revealed typical hyphae of mucormycosis.

Pneumocystis carinii pneumonia: role of high resolution computed tomography

Pneumocystis carinii (PC) is a common opportunistic infection in renal transplant recipients and requires an early diagnosis for its successful treatment. For its definitive diagnosis PC needs to be demonstrated in bronchoalveolar lavage (BAL) fluid. At times BAL may not be possible or get delayed. In such conditions typical appearances seen on high resolution CT of the chest help in early diagnosis of PC pneumonia (PCP). This easily performed procedure helped in early diagnosis of PCP in two patients.

Influence of HLA compatibility on renal graft survival using live unrelated & cadaver donors in India

BACKGROUND & OBJECTIVES

Living unrelated donor (LURD) renal transplantation has shown a rising trend over the last 5 yr at our center following the passing of The Transplantation of Human Organs Act by the Government of India in 1994. In this paper, the results of LURD and cadaver (CAD) donor renal transplantation are compared. We have also looked into factors that have a bearing on graft survival such as the extent of HLA mismatch (MM), infections, acute rejections (AR), donor age and sex.

METHODS

A total of 42 LURD and 25 CAD renal transplants performed between March 1994 and February 1999 has been included in the study. HLA typing, panel reactive antibody (PRA) screening and T and B cell cross match assay were performed by the complement dependent cytotoxicity (CDC) method for all patients.

RESULTS

The graft survival rates were generally higher in the LURD category as compared to the CAD group and were significant at 6 month period (90 vs 56%, P = 0.002). A follow up of the patients up to 60 months revealed a matching effect since the 3, 4 allele MM group had better survival rates as compared to the 5, 6 MM group. Twenty six of the 67 recipients (39%) experienced episodes of acute rejection (AR). Patients with 3, 4 MM had fewer such episodes than those with 5, 6 allele MM (P < 0.05). Of the 32 deaths, 20 were those with a functional kidney, of which 15 were caused by severe infections.

INTERPRETATION & CONCLUSION

Better HLA matching ensures fewer episodes of rejection and better long term graft survival in comparison to the poorly matched grafts. The graft survival for LURD recipients was appreciably higher than that of CAD recipients.

Results of renal transplantation on conventional immunosuppression in second decade in India: a single centre experience

BACKGROUND

In-spite of many renal transplant (RT) centres in the country, there is paucity of data on the survival results in India. Furthermore, there is hardly any data of results in second decade. In this study we present the results of RT in second decade at our centre.

METHODS

RT at our hospital is being done since 1972. First eight years saw occasional RT and complete data is not available in these patients. So, we have excluded these patients from the study. We have included rest all 144 patients who had RT between Jan. 1981 to Dec. 1989, so as to have at least 10 years of follow-up or more. All these patients were on conventional immunosuppression.

RESULTS

Of the 144 patients, 126 (87.5%) were males and the mean age was 29.5 +/- 8.5 years (range 14-54). Basic disease was presumed chronic glomenulonephritis (CGN) in 79.9%, vesicouretenic reflux (VUR) in 8% and diabetic nephropathy in 1.4% patients. Mean number of haemodialysis (HD) and blood transfusion before RT were 44 +/- 24.7 and 8.9 +/- 4.7 (range 0-25), respectively. Mean donor age was 40.9 +/- 10.1 year (range 18-62). HLA matching was haploidentical in 74.5% cases, HLA identical in 3% cases and 11.5% were less than two-antigen match. Of the 63% patients, who had at least one acute rejection (AR) during their follow-up, 78.8% cases had this AR within first three months after the renal transplant. During 10 years of follow up, 65 patients died (23 with normal graft function and 42 with chronic rejection) and 17 lost to follow-up. Eight patients lost their graft but were surviving at 10 years and 54 had functioning graft till the time of analysis. With mean follow-up of 83.9 +/- 61.2 (range 1-216) months, 10-year actuarial patients and graft survival was 53% and 47%, respectively. Graft half-life in these patients is 92 months. In multivariate analysis of the donor age, number of blood transfusion (BT), degree of HLA matching and AR, only AR was found to be statistically correlated with the graft outcome (p=0.004).

CONCLUSION

Our study concludes that in our set-up during eighties, on conventional immunosuppression, actuarial patient and graft survival at 10 year is 53% and 47%, respectively with graft half-life being 92 months. Only acute rejection has been found to affect the graft outcome in these patients.

Hepatitis C virus related cryoglobulinemic glomerulonephritis

A 46 years male presented with skin rash and acute nephritic syndrome. He had history of jaundice four months back. Rheumatoid factor and cryoglobulins were present in the serum. Although anti-HCV antibodies were negative, HCV RNA was detected by polymerase chain reaction. Kidney biopsy showed membranoproliferative glomerulonephritis and thrombi in the lumen of the glomerular capillary loops. His renal functions improved with steroids.

Tandem plasmapheresis and hemodialysis

Many patients requiring plasmapheresis (PE) have renal failure and also need hemodialysis. If done separately almost 6-7 h is required. Hence, we decided to perform the procedures simultaneously in those patients requiring both PE and hemodialysis. The plasmafilter was inserted into the extracorporeal circuit after the hemodialyzer. A total of 8 such sessions of tandem PE and hemodialysis were performed in 2 patients. This is called tandem PE/hemodialysis. The total procedure was completed in the same time as is required for routine hemodialysis. The total amount of priming fluid is also less when PE and hemodialysis are performed separately. Thus, it is economically beneficial to the hospital and also convenient to the patient. Apart from transient episodes of hypotension, which were corrected by saline infusion, no other complications were noted.

Chronic interstitial nephritis following parenteral copper sulfate poisoning

A 21-year-old male patient was admitted with acute renal failure and intravascular hemolysis following suicidal parenteral copper sulfate poisoning. He developed metabolic acidosis and septicemia; and was treated with intensive hemodialysis, blood transfusions and antibiotics. After remaining anuric for 4 weeks, his urine output gradually increased. However his renal functions improved only partially. Renal biopsy done 8 weeks after the episode showed chronic tubulo-interstitial nephritis (CIN). This is the first reported case showing CIN following acute copper sulfate intoxication.

Successful pregnancy outcome in advanced chronic renal failure

A 24 years female of advanced chronic renal failure due to lupus nephritis presented with pregnancy of eight weeks duration she continued the pregnancy against medical advice. At 29 weeks gestation further deterioration of renal function prompted weekly dialysis and hospitalisation for intensive maternal and fetal monitoring. At 35 weeks she was safely delivered by elective caesarian section. This is the first case of dialysis during pregnancy to be reported from India.

Impact of hepatitis C virus infection on renal transplant outcome in India--a single centre study

BACKGROUND

Hepatitis C virus (HCV) infection is currently the main cause of hepatotropic viral infection in renal transplant (RT) recipient throughout the world. Contrary reports are available as regard graft and patient survival and liver disease outcome in these patients. From India, outcome of HCV positive patients following RT has not been documented. Herewith, we present results of RT in HCV positive patients at our centre.

METHODS

Study design was prospective case control with primary end point being graft and patient survival and the exposure being HCV infection. Between June 1995 till February 1998, 128 patients had RT at our hospital, of which, 37 (28.9%) were anti-HCV positive at the time of RT. All the patients were on triple immunosuppressive therapy. As a policy of unit, none of the donor had HBV and/or HCV infection. Anti-HCV positive patients formed the subjects (Gr. I), while anti-HCV negative patients severed as control (Gr. II). Anti HCV was done using 3rd generation ELISA tests kit. HCV-RNA could not be done due to non-availability. None of the positive patient was treated with anti-viral therapy. Acute rejection, serious infections, patient and graft survival and outcome of liver disease was compared in these patients.

RESULTS

Mean age of the patients, number of males, number of pre-RT haemodialysis and blood transfusion, donor age and HLA-mismatch were comparable in both the groups. Mean follow-up in Gr. I was 28 +/- 9.4 months and in Gr. II 31.4 +/- 7.6 months. At the end of this follow-up, acute rejection was seen in 43% and 33.3% patient in Gr. I and II respectively. In Gr. I, serious infections were seen in 30% while the same in Gr. II was 11.8% (p < 0.01). There was no difference in graft survival in Gr. I and II (72% and 66%) and the patient survival were also similar (72% and 66%). Of the deaths in Gr. I, 80% died of sepsis and 20% died of liver cell failure related to one each of hepatitis B and hepatitis E. Of the deaths in Gr. II, 65% died of sepsis and 17% died of hepatic cell failure. But, there was no difference in causes of deaths in these two groups. In both the groups, none of liver related death was due to isolated HCV infection. There was no effect of donor age, HLA mismatch, number of haemodialysis and pre-RT blood transfusion on the survival of graft as well as patient.

CONCLUSION

In conclusion, HCV infection is major problem in RT with us. In a short follow-up of nearly 30 months, graft and patient survival is same in HCV positive and negative patients. However, serious infections are significantly more common in HCV positive patients.

Role of supravital staining of urine sediment and bright field microscopy in diagnosis of acute renal failure in bedside medicine

BACKGROUND

An early accurate etiological categorization of acute renal failure (ARF) into acute glomerulonephritis (AGN), acute tubular necrosis (ATN) and acute interstitial nephritis (AIN) is very important in clinical medicine.

METHODS

To evaluate the efficacy of a simple, cheap supravital staining method developed in our laboratory, we examined urine of 32 cases of ARF at their initial presentation in oliguric phase, which were later biopsied. The stain consisted of 1% crystal violet and 0.5% safranin in normal saline. The coverslip preparations of coded and stained urine sediments were examined under ordinary bright field microscope (BFM) by two independent observers.

RESULTS

The renal biopsy showed 12 cases of AGN, 12 ATN and 8 AIN. The diagnosis could be predicted by supravital staining method in 75% cases with 95% uniformity among two observers with a sensitivity of 85.7% for AGN followed by AIN (80%) and ATN (75%).

CONCLUSION

Thus this simple supravital staining technique can be used with ordinary BFM for accurate urine sediment analysis in cases of ARF in bedside medicine.

Spectrum of renal diseases in Indian adults

INTRODUCTION

Inspite of nephrology as a specialty since seventies, there is still paucity of data regarding the spectrum of renal diseases in India. Available literature from few hospitals shows data on specific clinical syndrome of renal diseases or specific renal diseases rather than the overall spectrum as a whole. This information will be useful for better resource management.

MATERIAL AND METHODS

We studied spectrum of renal diseases among 14,796 patients presenting for the first time to nephrology outpatients between January 1987 to Oct. 1998. Majority of patients in our clinic were adults. Patients 14 years or below who mostly attend pediatric renal unit of the hospital were excluded from the analysis. Till 1991, the study was retrospective but after 1991, patients were followed prospectively. Patients were grouped according to classical renal syndrome. After the initial presentation, patients were followed subsequently till their last follow-up in the clinic or till the time of reporting the present data.

RESULTS

Mean age of patients was 38.69 +/- 15.5 years with male predominance in majority of presentations. Chronic renal failure (CRF), nephrotic syndrome (NS), nephritic syndrome and hypertension were the four common presentations seen in 47.8%, 15.03%, 4.6% and 4.9% cases respectively. Other presentations were acute renal failure (1.9%), urinary tract infection (2.9%), stone disease (4.6%), obstructive uropathy (2.1%), isolated haematuria (1.2%) and asymptomatic urinary abnormalities (0.3%). Chronic glomerulonephritis was seen in 49.4% cases of CRF followed by diabetic nephropathy in 28.4% cases. Of the nephrotic syndrome cases, primary glomerulonephritis was seen 58.5% cases, of which minimal change disease was the commonest cause in 38% cases. Of the secondary glomerular diseases, diabetic nephropathy was commonest cause of NS (53%) followed by amyloidosis (16.4%) and lupus (8.3%). Tuberculosis was the commonest cause of renal amyloidosis seen in 50% cases. Of the nephritic syndrome, post-infective glomerulonephritis was commonest cause followed by rapidly progressive glomerulonephritis being the second commonest cause. In the hypertensive group, essential hypertension was the commonest cause followed by renovascular hypertension.

CONCLUSION

It is the first large study of its kind presenting the spectrum of renal diseases in the tertiary-care government hospital of the country and we expect the disease pattern to be reasonably similar in other similar government hospital of the country. Chronic renal failure, nephrotic syndrome and diabetes are three major diseases, with which we have to deal maximum. As CRF in young male patients is the largest load, with its wide social and economical implications in the Indian context, we must gear up to organise ourselves for providing the best possible care to these patients with the limited resources.
