Clinico-microbiological Profile and Outcomes of Asymptomatic Bacteriuria in Pregnancy.

Background: Asymptomatic bacteriuria (ASB) during pregnancy can lead to symptomatic urinary tract infection (UTI), with increased fetal and maternal morbidity and mortality. We evaluated the incidence, clinical and microbiological profile, and outcome of ASB in pregnant women attending our antenatal clinic. Materials and Methods: This prospective study was conducted on 3769 pregnant women in a routine antenatal clinic at a tertiary care center. Participants were divided into two groups, ASB and non-bacteriuria. Data were collected in a standard proforma and analyzed using the software Statistical Package for the Social Sciences (SPSS) v. 20. Results: The incidence of ASB was 3.29% (124/3769). Majority of the women were in the age group of 21-30 years (78.76%, n = 89). Escherichia coli (61.06%) was the most common organism isolated. Maternal anemia (30.08% and 2.93% in the ASB and non-bacteriuria groups, respectively), low birth weight (LBW; 42.5% and 27.98% in the ASB and non-bacteriuria groups, respectively), intrauterine death (4.4% and 1.4% in the ASB and non-bacteriuria groups, respectively), and preterm delivery (37.2% and 22.31% in the ASB and non-bacteriuria groups, respectively) were were associated with ASB (P = 0.001). Conclusion: ASB was associated with maternal anemia, preterm delivery, intrauterine death, and LBW. Early detection and treatment of ASB may result in favorable maternal outcome.

A Prospective Observational Study of Renal Involvement in Hematological Malignancies.

Patients with hematological malignancies (HMs) are at high risk of infections and comorbidities that substantially increase the occurrence of renal failure. Thus, the management of renal dysfunction in patients with HMs is crucial. The current study aimed to determine the incidence of renal involvement in patients with HMs and analyze their clinical profile in the context of renal disorders. A prospective observational study was conducted on 200 patients suffering from various HMs. Renal involvement was determined through blood and urine analyses. The mean age of the patients was 51.84 ± 17.47 years, with the male-to-female ratio being 1.5:1. Multiple myeloma (MM) (30.5%) and non-Hodgkin's lymphoma (NHL) (30.5%) were the most commonly observed types of HM, whereas plasmacytoma (1%) was the least observed. Moreover, 39.5% and 16.5% of patients were diagnosed with moderate and severe anemia, respectively. Mean calcium, creatinine, and blood urea nitrogen levels were 8.97 ± 1.19 mg/dL, 1.41 ± 1.37 mg/dL, and 16.83 ± 14.50 mg/dL, respectively. Mean sodium, potassium, and uric acid levels were 135.49 ± 6.79 mEq/L, 4.157 ± 0.65 mEq/L, and 5.81 ± 2.82 mg/dL, respectively. Twelve percent of the patients (24 out of 200) presented with renal insufficiency and nephrotic syndrome. Ten patients were diagnosed with NHL, 10 patients with MM, two with chronic myeloid leukemia, and two with acute myeloid leukemia. The causes of renal impairment in most cases were patchy interstitial lymphoid infiltrates, cast nephropathy, acute tubular necrosis, and minimal change disease.

Clinico-biochemical Profile of Biopsy-proven Minimal Change Disease in Adults from a Tertiary Care Center in South India.

Minimal change disease (MCD) is the most common cause of nephrotic syndrome (NS) in children, and in adults, it contributes to 10%-25% of NS. MCD in adults follows a slightly different course associated with increased incidence of steroid resistance, hematuria, and HTN. This is a prospective-record analysis study aimed to analyze the profile of MCD in adults, response to treatment, and relapse rates. A retrospective observational study was carried out and data were collected retrospectively from all biopsy-proven MCD patients between 2012 and 2018. A total of 86 adults were diagnosed to have biopsy-proven MCD. Of these, 32 were excluded due to insufficient data/lost for follow-up. The IBM SPSS Statistics version 22.0 was used for the statistical analysis. Descriptive analysis includes expression of all the explanatory and outcome variables in terms of frequency and proportions for categorical variables whereas in terms of mean ± standard deviation for continuous variables. Chi-square test was used to compare the age, gender, remission, renal failure and response of different drugs, treatment durations, comorbidity conditions, relapse episodes, and different types of infections based on the degree of proteinuria among study patients. A total of 54 biopsy-proven adult MCD patients were analyzed. The mean age of the patients studied was 36.67 years, with the oldest patient being 76 years. In the study group, 37 (68.5%) patients were male and 14 (31.5%) were female. In the study population, 20 (37%) were hypertensive, 3 (5.6%) were diabetic, and 10 (18.5%) had renal failure at presentation. On treatment, 52 out of 54 patients received steroids, of which 41 (75.9%) were steroid responsive, 6 (11.1%) steroid dependent, and 7 (13%) steroid resistant. The mean time for remission in steroidsensitive patients was 8.8 weeks. Among the steroid-dependent and steroid-resistant patients, 11 patients received calcineurin inhibitors (CNIs), of which 3 were CNI resistant. In the study Group 1 patient received cyclophosphamide and two received rituximab. In the study population, two patients failed to achieve remission and one patient was initiated on hemodialysis and later lost for follow-up. Minimal change NS is a type of NS which is highly responsive to steroids with good prognosis in children. Adult MCD patients require a higher and prolonged course of steroid when compared to children. CNIs and rituximab form a promising second-line drug in patients who are steroid resistant/dependent. However, CNI dependency or relapse after stopping steroids is a concern.

Clinical features and histological patterns of lupus nephritis in a single center of South India.

Renal involvement occurs in up to 60% of patients with systemic lupus erythematosus (SLE) and signifies a poor prognosis. The class of lupus nephritis (LN), determined on renal biopsy evaluation, guides the therapeutic management and has prognostic connotations. Our aim is to determine the clinicolaboratory features and histopathological patterns of LN at presentation in our local (South Indian) population. The study was conducted in a tertiary care hospital in South India between 2009 and 2014 on SLE patients with clinical evidence of LN. The renal biopsies were examined by light and immunofluorescence microscopy and were classified according to the International Society of Nephrology/Renal Pathology Society Classification of LN. A total of 46 patients were included, with age range of 12-60 years and a female to male ratio of 8.2:1. Arthritis, dermatological manifestations, and fever occurred, respectively, in 43.5%, 39.1%, and 30.4% of the cases. Class IV LN was present in 17 (37.1%), Class III LN in ten (21.7%), Class II LN in nine (19.5%), Class V LN in eight (17.4%), Class I LN in one (2.2%), and Class VI LN in one (2.2%) patients. Antinuclear antibody (ANA) and dsDNA positivity were present, respectively, in 82.6% and 65.2% of the patients. The most common pattern of LN was Class IV LN followed by Class III LN. Relatively higher proportions of ANA and anti-dsDNA positivity were present in proliferative LN, and there was a high frequency of arthritis at presentation in our LN patients.

Nondiabetic Renal Disease in type 2 Diabetes Mellitus Patients: A Clinicopathological Study.

BACKGROUND: The prevalence of nondiabetic renal disease (NDRD) among type 2 diabetics varies widely depending on the populations being studied and the selection criteria. Also, for patients found to have NDRD different predicting factors have been identified by different studies. OBJECTIVES: TO DETERMINE: (i) Frequency and spectrum of NDRD in type 2 diabetics with atypical clinical renal disease, in our set up and (ii) common clinical markers that are associated with NDRD in our local population. MATERIALS AND METHODS: Ninety-three type 2 diabetic patients with atypical clinical renal disease who had undergone renal biopsy to rule out NDRD were recruited. Patients were grouped into Group 1 with isolated NDRD, Group 2 with NDRD superimposed on diabetic nephropathy (DN), and Group 3 with isolated DN; and their clinical and biochemical parameters were statistically analyzed using analysis of variance, Kruskal-Wallis test, and Chi-square tests of statistical significance. RESULTS: 68.8% of the patients had NDRD with or without concurrent DN. Patients with isolated NDRD had shorter duration of diabetes compared to the other groups. Absence of retinopathy and presence of microscopic hematuria and active urinary sediment had positive predictive value of 79.24, 81, and 100%, respectively, for NDRD in type 2 diabetics. Chronic interstitial nephritis was the commonest NDRD and membranous glomerulonephritis was the commonest glomerular NDRD in our setup. INTERPRETATION AND CONCLUSIONS: The frequency of NDRD in type 2 diabetics with atypical clinical renal disease is high in our setup thereby making the renal biopsy procedure imperative to rule out the same. Shorter duration of diabetes, absence of retinopathy, presence of microscopic hematuria, and active urinary sediment are markers associated with NDRD in type 2 diabetes with clinical renal disease.

Evaluation of high sensitivity C-reactive protein and glycated hemoglobin levels in diabetic nephropathy.

Diabetic nephropathy (DN) is one of the major long-term complications of diabetes mellitus (DM). Type 2 DM is frequently associated with an inflammatory status, but limited information is available on the relationship between low-grade inflammation and DN. The aim of the study is to determine the serum level of high sensitivity C-reactive protein (hsCRP) in DN patients and to compare with that of normal subjects and to study the association between serum hsCRP levels and glycated hemoglobin (HbA1c) levels. Fifty DN patients in the age group of 50- 60 years with more than ten years of duration of diabetes were recruited for this study and 25 age-and sex-matched healthy subjects were included in this study as controls. Serum hsCRP levels were measured by turbidometry method. There was a statistically significant increase in serum hsCRP levels in DN cases as compared to normal controls. The hsCRP levels showed a positive correlation with HbA1c in DN. These results suggest that estimation of serum hsCRP levels and aiming at good glycemic control help in early intervention and prevention of further com-plications in diabetic patients.

Opportunistic infections in a renal transplant recipient.

With the present progress in transplantation procedures, there is an improvement in patient and allograft survival. However, the immunosuppression necessary to sustain the allograft predisposes these transplant recipients to infection, which is now a significant cause of morbidity and mortality. We describe a case of a 30-year-old renal transplant recipient with two opportunistic infections, namely, primary cutaneous aspergillosis and intestinal tuberculosis, with terminal enterococcal pleuritis and peritonitis. Control of the degree of immunosuppression, and prompt recognition and treatment of infection are vital for successful organ transplantation.
