Breast cancer has emerged as a major health problem among women in India. There are few Indian studies which have looked at prevalence of molecular subtypes of breast cancer in Indian population. The primary objective of our study was to find out the prevalence of various molecular subtypes in operated cases of breast cancer patients presenting to us. Three hundred sixty patients who were operated in our department were analysed. Clinicopathological features of all cases were recorded. Classification into various molecular subtypes was done using St. Gallen 2013 criteria. Luminal B HER2 negative was the predominant molecular subtype in our study population constituting 30.3% of patients. The percentage of aggressive subtypes, viz. triple negative breast cancer and HER2 enriched, were 21.7% and 11.4% respectively. Only 19.4% of patients in our study population had tumour size ≤ 2 cm with nodes being positive in 56.9% of our patients at presentation. Data from our study and other studies published from India show that the two most aggressive subtypes of, viz. triple negative breast cancer and HER2 enriched, may be more prevalent in our population as compared to western population., Competing Interests: Conflict of InterestThe authors declare no competing interests., (© Indian Association of Surgical Oncology 2021.)

Background and Aim: There is a paucity of data on the clinical presentations and outcomes of Corona Virus Disease-19 (COVID-19) in patients with underlying liver disease. We aimed to summarize the presentations and outcomes of COVID-19-positive patients and compare with historical controls., Methods: Patients with known chronic liver disease who presented with superimposed COVID-19 (n = 28) between 22 April 2020 and 22 June 2020 were studied. Seventy-eight cirrhotic patients without COVID-19 were included as historical controls for comparison., Results: A total of 28 COVID-19 patients (two without cirrhosis, one with compensated cirrhosis, sixteen with acute decompensation [AD], and nine with acute-on-chronic liver failure [ACLF]) were included. The etiology of cirrhosis was alcohol (n = 9), non-alcoholic fatty liver disease (n = 2), viral (n = 5), autoimmune hepatitis (n = 4), and cryptogenic cirrhosis (n = 6). The clinical presentations included complications of cirrhosis in 12 (46.2%), respiratory symptoms in 3 (11.5%), and combined complications of cirrhosis and respiratory symptoms in 11 (42.3%) patients. The median hospital stay was 8 (7-12) days. The mortality rate in COVID-19 patients was 42.3% (11/26), as compared with 23.1% (18/78) in the historical controls (p = 0.077). All COVID-19 patients with ACLF (9/9) died compared with 53.3% (16/30) in ACLF of historical controls (p = 0.015). Mortality rate was higher in COVID-19 patients with compensated cirrhosis and AD as compared with historical controls 2/17 (11.8%) vs. 2/48 (4.2%), though not statistically significant (p = 0.278). Requirement of mechanical ventilation independently predicted mortality (hazard ratio 13.68). Both non-cirrhotic patients presented with respiratory symptoms and recovered uneventfully., Conclusion: COVID-19 is associated with poor outcomes in patients with cirrhosis, with worst survival rates in ACLF. Mechanical ventilation is associated with a poor outcome.

Introduction: Transmission of hepatitis E virus (HEV) through transfusion has been reported from countries where genotype 3 virus is predominant. Data from countries with predominantly genotype 1 HEV, such as India, are limited. We studied the risk of HEV transmission following transfusion of blood or blood components in India., Methods: Adult patients undergoing cardiac surgery who received transfusion of blood or blood products in the peri-operative period and who lacked history of any transfusion or surgery in the preceding 1 year were studied. A pre-transfusion blood specimen was collected for IgG anti-HEV antibody test. For the participants who were seronegative for anti-HEV, follow up specimens were collected at every 2-3-month intervals for up to 6 months after surgery and were tested for IgM and IgG anti-HEV antibodies., Results: Of the 335 participants originally enrolled, 191 (57%) could be followed up. Of them, 103 (53.9%) were seropositive for HEV IgG at baseline and were excluded. Of the remaining 88 participants (age 42 ± 14.1 years; 55 [63%] male), none reported hepatitis-like illness during the follow up period of 81 ± 23 days. Also, none of these 88 participants was found to have seroconversion to anti-HEV IgM or IgG positivity in the follow up specimens., Conclusion: Transfusion-mediated transmission of HEV was not observed in our cohort and may be infrequent in the Indian population, where genotype 1 is the predominant HEV type.

Background: Little is known about the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in Ladakh, a mountainous region with low population density. We, therefore, determined these and tried to identify risk factors associated with these infections., Methods: Randomly selected residents of Ladakh region were tested for hepatitis B surface antigen (HBsAg), antibodies to hepatitis B core antigen (anti-HBc) and antibodies to HCV (anti-HCV). A subset of HBsAg-positive persons were tested for hepatitis B e-antigen (HBeAg) and HBV DNA and those with anti-HCV for HCV RNA. Viral genotype was also determined., Results: Of the 2674 subjects, 141 (5.3%) tested positive for HBsAg, i.e. had current HBV infection and 339 (12.7%) tested positive for either HBsAg and or anti-HBc, i.e. had either current or past infection with HBV. Anti-HCV antibody was detected in 22 (0.8%) subjects. The HBsAg positivity rate was higher in Kargil district (8.3%) than in Leh district (3.3%). No particular risk factor was identified for either infection. Of the 141 and 22 specimens that contained HBsAg and anti-HCV, respectively (one had both), 74 and none tested positive for HBV DNA and HCV RNA, respectively. Of the 29 specimens that had sufficient HBV DNA for genotyping, 21, 7, and 1 specimens had HBV genotypes D, C, and A, respectively., Conclusion: The overall prevalence of HBV infection seems to be higher in Ladakh region, especially the Kargil district. The prevalence of anti-HCV was similar to that in other parts of India. ᅟ ᅟ.

Hepatitis C virus (HCV) is a parenterally-transmitted hepatotropic virus that often causes chronic infection, which can progress to cirrhosis and hepatocellular carcinoma. Development of highly effective direct-acting anti-viral agents (DAAs) has led to a paradigm change in the treatment of HCV infection over the last 4-5 years. Patients with chronic kidney disease (CKD) are at a higher risk of acquiring HCV infection. In these patients, diagnosis of HCV infection, assessment of the consequent liver disease and management of HCV infection pose some specific problems. This article reviews the available recent information on HCV infection and CKD, including the association between these conditions and their effect on each other, and prevention, evaluation, and management of HCV infection in persons with CKD. This review looks at this issue particularly from the perspective of readers in Asia, especially India, since the epidemiology of HCV-CKD association and the repertoire of anti-HCV drugs available in this region differ from those elsewhere.

Sentinel lymph node (SLN) biopsy has become the standard of care in axillary staging of breast cancer patients who are clinically node negative as it reduces the morbidity of axillary nodal dissection. SLN biopsy using blue dye and radioisotopes have high identification rates but its limitations include anaphylaxis, disposal of radioactive waste, and potential second surgery in up to 35% of patients who show nodal metastases on SLN biopsy. Contrast-enhanced ultrasound (CEUS) has the potential for SLNs to be identified without the aforementioned risks. CEUS involves the administration of intravenous contrast agents containing microbubbles of perfluorocarbon or nitrogen gas. The bubbles greatly affect ultrasound backscatter and increase vascular contrast in a similar manner to intravenous contrast agents used in CT and MRI. It is safe and easily performed with no requirement for ionizing radiation and no risk of nephrotoxicity. Microbubbles are taken up by lymph nodes when injected directly into tissues, including sub-areolar injection in the breast cancer patient. This method may prove valuable in patients with ductal carcinoma in situ, where operative SLN biopsy remains controversial, and in women undergoing prophylactic mastectomies for high risk. This technique may also have a role after neoadjuvant chemotherapy where frequently there is fibrosis in the treated SLNs.

Background: Hepatitis E virus (HEV) is transmitted primarily through contaminated water and food. Recently, HEV viremia in blood donors and transfusion-related transmission of HEV have been reported, leading to calls to screen donated blood for this virus. However, these data are from regions where genotype 3 HEV is predominant. In India, where human infections are caused only by genotype 1 HEV, the frequency of subclinical HEV viremia is unknown., Methods: Minipools of sera prepared from three donor units each from our institution's  blood bank in Lucknow, India, were tested for HEV RNA using a sensitive amplification-based assay. A randomly selected subset was also tested for IgG anti-HEV antibodies using a commercial (Wantai) immunoassay., Results: Sera from 1799 donors (median [range] age 30 [18-63] years; 1746 [97.0%] men) were collected (June-July 2016, 900; November-December 2016, 899). Of these, 17 (0.95%), 16 (0.90%), and 3 (0.17%) tested positive for HBsAg, anti-HCV, and anti-HIV antibodies, respectively. None of the donors tested positive for HEV RNA. Of 633 randomly selected donors (age 30 [18-63] years, 613 [96.8%] male) tested for IgG anti-HEV, 383 (60.5%) tested positive. Seropositivity rate increased with age, being 70/136 (52%), 177/299 (59%), 100/154 (65%), 30/34 (88%), and 6/10 (60%) in the 18-24, 25-34, 35-44, 45-54, and 55 years or older age groups, respectively., Conclusions: In healthy blood donors from northern India, HEV viremia is infrequent though anti-HEV antibody prevalence is high. This suggests that asymptomatic HEV viremia may be less frequent in areas with genotype 1 predominance than those with genotype 3 predominance.

Hepatitis B virus (HBV) has several genotypes. In the Indian population, genotypes A and D are the most frequent. HBV infection is hyper-endemic in the Lahaul and Spiti district in Himachal Pradesh; however, the virus genotype in this area is not known. We sequenced a 398-nucleotide segment of HBV genome that included parts of pre-S1/S2 and polymerase genes from 17 specimens from this district, and assigned a viral genotype to these. Of the 17 specimens studied, 13 (76% [95% confidence interval = 50-92%]) showed the presence of genotype C HBV; the remaining four were genotype D (n = 4; 24%) HBV. Prevalence of genotype C HBV was much higher in the district than in other parts of India. This may reflect the historical mixing of this population with that in China. Since genotype C has a higher risk of chronicity and mother-to-child transmission, prevention of HBV infection may need particular emphasis in this area.

Objective: To compare the efficacy and safety of mifepristone followed by misoprostol with misoprostol alone in the management of early pregnancy failure (EPF)., Study Design: A randomized double-blind placebo-controlled clinical trial., Methods: Ninety-two women with EPF ≤12 weeks were recruited and randomly allocated to receive either mifepristone 200 mg ( n  = 46) or placebo ( n  = 46). Forty-eight hours later, patients in both the groups were given 800 µg misoprostol per-vaginum. If no expulsion occurred within 4 h, repeat doses of 400 µg misoprostol were given orally at 3-hourly interval to a maximum of 2 doses in women ≤9 weeks by scan and 4 doses in women >9 weeks by scan., Results: Pre-treatment of misoprostol with mifepristone significantly increased the complete abortion rate (86.7 vs. 57.8%, p  = 0.009) and, hence, reduced the need for surgical evacuation (13.3 vs. 42.2%, p  = 0.002), induction to expulsion interval (4.74 ± 2.24 vs. 8.03 ± 2.77 h, p  = 0.000), mean number of additional doses of misoprostol required (0.68 vs. 1.91, p  = 0.000), and side effects., Conclusion: Use of mifepristone prior to misoprostol in EPF significantly improves the efficacy and reduces the side effects of misoprostol alone., Competing Interests: Compliance with Ethical StandardsNone.

Background: Hepatitis E is caused by infection with hepatitis E virus (HEV), which has four well-known genotypes. Genotypes 1 and 2 HEV have been reported from human cases in areas where the disease is highly endemic. By contrast, genotypes 3 and 4 HEV, which primarily infect several animal species worldwide, have been reported mainly from sporadic human cases in non-endemic areas such as Japan and high-income countries of Europe and North America. To determine whether genotype 3/4 HEV cause sporadic disease in India, a disease-endemic area, we determined HEV genotype in a group of patients with such disease., Methods: A part of the HEV open reading frame (ORF) 1 was amplified and sequenced from sera of 74 patients with sporadic acute viral hepatitis E from four cities in India. The sequences were compared with prototype sequences for various HEV genotypes and subgenotypes and analyzed using phylogenetic tools to determine the genotype of the isolates. For 12 specimens, a part of HEV ORF2 was also similarly analyzed., Results: Partial ORF1 sequences of all the 74 isolates belonged to genotype 1 HEV, with 88.2% to 100% nucleotide identity with the prototype genotype 1 isolates. Partial ORF2 sequences for all the 12 isolates also belonged to genotype 1 HEV. On phylogenetic analysis, 71 isolates clustered with prototype genotype 1a HEV; the remaining three isolates were located between subgenotypes 1a and 1c but were closer to the former., Conclusion: Human sporadic acute hepatitis E in India is caused almost exclusively by genotype 1 HEV.

Objective: To study the prevalence, clinical and laparoscopic characteristics of endometriosis in infertile women., Study Design: This is a hospital-based prospective study., Patients: Five hundred and two (502) patients underwent diagnostic laparoscopy for evaluation of cause for infertility. Staging of endometriosis was done according to the rAFS scoring system., Results: Out of 502 women, 276 (54.98 %) showed the presence of endometriosis, while 226 (45.01 %) did not have endometriosis. One hundred and eighty-three (66.3 %) women had stage I endometriosis, 49 (17.77 %) had stage II, 23 (8.33 %) had stage III and 21 (7.6 %) had stage IV endometriosis., Conclusion: More than 50 % of patients in our study were asymptomatic; however, the presence of menorrhagia, dysmenorrhoea, dyspareunia and chronic pelvic pain are also clinically statistically significant. So, we would like to recommend the evaluation and treatment of a patient reporting in gynaecological OPD with the above-mentioned complaints with high suspicion of endometriosis.

Background: Solitary kidney may be congenital or as a result of nephrectomy. There is a lot of literature available on quality of life in these patients, but there is limited data on pregnancy outcome., Objectives: To study pregnancy outcome in patients with solitary kidney either congenital or due to nephrectomy., Materials and Methods: Study Design This is a retrospective observational study conducted at tertiary health center in Ahmedabad, from 2011 to 2014. Sample Size There were 164 patients of solitary kidney, out of which two patients had congenital solitary kidney and the remaining had solitary kidney due to nephrectomy. Among 164 patients, 96 (58.53 %) patients had completed family, 37 (22.56 %) patients did not try for pregnancy, 15 (9.14 %) patients have conceived, 12 (7.3 %) were lost to follow up and 4 (2.43 %) patients were infertile. Method Patients in reproductive age group (20-40 years), with solitary kidney either congenital or due to nephrectomy, were included. Maternal and fetal outcome was studied, and patients were followed up till 2 years postpartum. Exclusion Criteria Patients with solitary kidney due to post-renal transplant were excluded., Results: There were 15 (9.14 %) patients who had conceived, out of which 11 (73.33) patients delivered and 4 (26.67 %) patients had spontaneous abortion. Two patients developed gestational hypertension and one had preeclampsia. On follow-up, all babies were normal and none of them had delayed developmental milestones., Conclusion: Preconceptional counseling should be done in these patients regarding risk of developing preeclampsia during pregnancy and preterm delivery. These patients can have good pregnancy outcome with close monitoring during antenatal period.

Background: Direct-acting antiviral drugs (DAAs) are favored for the treatment of hepatitis C virus (HCV) infection. However, the experience with the DAAs currently available in India in the treatment of genotype-3 HCV is limited. We therefore reviewed our experience with these drugs in treating patients with chronic genotype-3 HCV infection, including those with cirrhosis., Methods: We prospectively followed adult patients with genotype-3 HCV infection who had received treatment regimens containing sofosbuvir with/without daclatasvir. Patients were categorized as chronic hepatitis C (CHC), compensated cirrhosis (CC), and decompensated cirrhosis (DC). They received either (i) sofosbuvir and ribavirin, with or without pegylated interferon (Peg-IFN) for 12 or 24 weeks, or (ii) sofosbuvir and daclatasvir, with or without ribavirin for 12 or 24 weeks. Response was assessed using HCV RNA testing after 2 or 4 weeks of treatment (rapid virological response [RVR]), at treatment completion (end-of-treatment response [ETR]) or 12 weeks after treatment completion (sustained virological response [SVR12])., Results: Of the 160 patients (90% treatment-naïve; CHC 49%, CC 32%, and DC 19%), 39 (24%) received Peg-IFN, sofosbuvir and ribavirin, 21 (13%) received sofosbuvir and ribavirin, and 100 (63%) received sofosbuvir and daclatasvir, with or without ribavirin. On intention-to-treat basis, RVR, ETR, and SVR12 in the entire cohort were 146/160 (91.3%), 151/160 (94.4%), and 147/160 (91.9%), respectively. Seven patients died (CC 2, DC 5) during treatment; four (2 CHC, 2 DC) patients discontinued treatment; and two patients with CC relapsed., Conclusions: Dual-DAA-based regimens were safe and highly effective in treating genotype-3 HCV infection in CHC and CC patients.

Increasing anthelmintic resistance and the impact of conventional anthelmintics on the environment, it is important to look for alternative strategies against helminth parasite in sheep. Important lipogenic enzymes like glucose-6-phosphate dehydrogenase (G-6-PDH) and malate dehydrogenase (MDH) show subcellular distribution pattern. Activity of G-6-PDH was largely restricted to cytosolic fraction while MDH was found in both cytosolic and mitochondrial fraction in Gastrothylax indicus. Following in vitro treatment with ethanolic and aqueous extracts of Punica granatum fruit peel and commercial anthelmintic, albendazole G-6-PDH activity was decreased by 19-32 %, whereas MDH was suppressed by 24-41 %, compared to the respective control. Albendazole was quite effective when compared with negative control and both the extracts. The results indicate that phytochemicals of plant may act as potential vermifuge or vermicide.

In recent past, direct-acting anti-viral drugs (DAAs) have become the standard of care for the treatment of hepatitis C virus (HCV) infection. However, the experience with the use of these drugs in Indian renal transplant recipients is limited. We retrospectively reviewed our experience with DAA-based treatment for HCV infection in such patients. Between April 2015 and December 2016, six adults (median age 41 [range 34-52] years, male 5; GT1 2, GT3 3, and GT4 1; including three with prior failed interferon-based treatment) had received genotype-guided, DAA-based anti-HCV treatment 1 to 158 (median 15) months after renal transplantation. Of them, four completed the planned 24-week treatment without any significant adverse event. One of them had increase in serum creatinine after 16 weeks of treatment with sofosbuvir and daclatasvir, with acute interstitial nephritis on kidney biopsy; his renal function improved on stopping the drugs. The other patient had preexisting mild renal dysfunction, which worsened after 8 weeks of sofosbuvir-ledipasvir treatment; this did not reverse on stopping treatment. All the six patients achieved undetectable HCV RNA after 4 weeks of treatment and also achieved sustained virologic response, i.e. lack of detectable HCV RNA in serum 12 weeks after stopping treatment. Overall, DAA-based treatment was effective in treating HCV infection in our renal transplant recipients; however, caution and monitoring of renal function during such treatment is advisable in patients who have additional factors that predispose to renal injury.

Anthelmintic activity of both ethanolic and aqueous extracts of Calotropis procera flowers, Azadirachta indica leaves and Punica granatum fruit peel in comparison with albendazole was evaluated through in vitro studies by the worm motility inhibition assay. Significant anthelmintic effects (p < 0.0005) were observed on live Gastrothylax indicus worm as evident from their mortality at 4 h post exposure to both ethanolic and aqueous extracts. Phytochemical analysis of extracts revealed the presence of phenols, alkaloids, saponins, tannins, flavonoids, steroids and triterpenoids. LC-50 values were determined to be 12.05 mg/ml ± 3.24 and 23.52 mg/ml ± 6.4 for C. procera , 24.37 mg/ml ± 4.11 and 21.02 mg/ml ± 4.6 for A. indica , 18.92 mg/ml ± 4.54 and 24.43 mg/ml ± 6.96 for P. granatum ethanolic and aqueous extracts respectively, whereas it was 29.23 μg/ml ± 4.51 for albendazole. The mean mortality index (MI) was 1.0 and 0.90 for C. procera , 0.90 for A. indica and 0.73 and 0.80 for P. granatum ethanolic and aqueous extracts respectively whereas for albendazole it was 1.0. Percent mean worm motility inhibition (%WMI) was observed to be between 70 and 100 % for different extracts.Various concentrations (5-5000 μg/ml) of all the plant extracts and albendazole were used to detect their cytotoxic effects against HeLa cell line to determine CC-50 by MTT assay. CC-50 values, of all the plant extracts were determined to be >1000 μg/ml and for albendazole it was found to be >10 μM. All the three plants can be potential sources for novel anthelmintics.

Purpose of the Study: To study the role of endometrial and subendometrial blood flow measured by 3D power Doppler as predictors of pregnancy in frozen embryo transfer (FET) cycles., Methods: A hospital-based prospective study of two hundred and twenty-one (221) women undergoing FET cycles with a triple-line endometrium ≥7 mm on day 14 endometrial and subendometrial blood flow was assessed using 3D power Doppler, and various indices endometrial volume, subendometrial volume and their vascularisation index (VI), flow index (FI) and vascularisation flow index (VFI) were obtained and compared between the pregnant and the non-pregnant group. Primary outcome was clinical pregnancy., Results: Out of 221 women, 97(43.89 %) became pregnant, while 124 (56.10 %) failed to become pregnant. The endometrial volume was comparable between the two groups. Endometrial VI, FI and VFI were significantly higher in the pregnant as compared to the non-pregnant group. There was a significant difference in subendometrial VI and VFI between the two groups, but FI was similar., Conclusions: Endometrial and subendometrial vascularity by 3D power Doppler can be a useful parameter in predicting pregnancy in FET cycles., Competing Interests: Compliance with Ethical Standards Conflicts of interest None Declared. Ethical statement Informed written consent taken from every patient to enroll them in this study.

Background: The number of patients undergoing renal transplant are increasing with time. Most of these patients fall in the reproductive age group, who are going to conceive sooner or later. But there are few recipients who either are infertile before transplant or became infertile due to underlying renal pathology responsible for transplantation., Objective: To study fertility outcome in female renal transplant recipients., Study Design: This is a retrospective study conducted at tertiary health center in Ahmedabad, from 2004 to 2014., Inclusion Criteria: Renal transplant recipients in the reproductive age group (20-40 years of age) were followed up in gynecology outdoor patient department., Sample Size: There were 211 female renal transplant recipients, out of which 113 (53.5 %) patients had complete family, 3 (1.41 %) patients were infertile, 16 (7.58 %) patients have conceived, 33 (15.63 %) patients were lost to follow-up and remaining 46 (21.8 %) did not try for pregnancy., Exclusion Criteria: Unmarried patients, divorced and widow patients were excluded., Results: Out of 19 patients, 16 patients conceived and 3 were infertile. The main cause of infertility in these patients was ovarian factor in 2 patients and tubal factor in 1 patient. Among 16 patients, 8 patients had missed abortion, 2 patients had preterm deliveries and 6 patients had term deliveries., Conclusion: Peritransplant and preconceptional counseling plays an important role for renal transplant recipients to help them understand the effect of renal pathology and transplantation on their fertility. They can have good fertility and pregnancy outcome with optimum functioning graft., Competing Interests: None. Ethical Approval It is an observational study carried out at IKDRC, Ahmedabad. The study does not involve experiment on any animal or human being. Informed Consent Informed consent was obtained from all individual participants included in the study.

Objective: To predict the effectiveness of granulocyte colony-stimulating factor (GCSF) in the treatment of persistent thin endometrium resistant to other treatments in frozen embryo transfer (FET) cycles., Study Design: This is a hospital-based prospective study., Patients: Thirty-five women with persistent thin endometrium (<7 mm) resistant to standard treatments were involved in this study., Interventions: Intrauterine infusion of GCSF (300 mcg/1 ml) was done in patients with thin endometrium on day 14 of FET cycles, and their endometrial thicknesses were measured after 48 h of infusion., Main Outcome Measures: The primary outcome was an increase in endometrial thickness and the secondary outcome measures were chemical and clinical pregnancies., Results: The endometrial thickness increased from 5.86 ± 0.58 to 6.58 ± 0.84 mm after GCSF infusion. In 19 of the 35 participants (54.28 %) endometrial thickness increased to ≥7 mm and they subsequently underwent embryo transfer. Of these, 3 (15.78 %) patients had chemical pregnancy, but there was no clinical pregnancy. In 16 participants, embryo transfer was canceled in view of insufficient endometrial thickness (<7 mm)., Conclusion: GCSF caused a small increase in endometrial thickness in women with persistent thin endometrium, but there was no improvement in their pregnancy rates., Competing Interests: Vineet Mishra, Sumesh Choudhary, Urmila Sharma, Rohina Aggarwal, Ritu Agarwal, Khushali Gandhi, and Nilesh Goraniya declare that they have no conflicts of interest. Informed consent All procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2008. Informed consent was obtained from all patients for being included in the study.

Background: Hepatic venous outflow tract obstruction (HVOTO) and extrahepatic portal venous obstruction (EHPVO) are important causes of portal hypertension and related complications in India. Both these conditions result from splanchnic venous thrombosis. In recent years, a V617F somatic mutation in Janus kinase 2 (JAK2) gene which is highly specific for myeloproliferative disorders has been detected in 40 % to 50 % and 30 % to 35 % of Western patients with HVOTO and EHPVO, respectively. However, data on this mutation in these conditions from Asian countries are limited., Methods: We looked for JAK2 V617F mutation in Indian patients with HVOTO (n = 40, median age 31 [range 17-51] years, 21 female) and EHPVO (n = 50, median age 23 [15-70] years, 25 female) by using two separate methods. Both the methods involved polymerase chain reaction using allele-specific primers. Positive results on one or both of these techniques were confirmed using DNA sequencing., Results: None of the 40 patients with HVOTO and only 1 of 50 patients with EHPVO was found to have JAK2 V617F mutation. In the one patient who was found to have this mutation, both the PCR methods and DNA sequencing showed positive results., Conclusion: Hypercoagulability associated with JAK2 V617F mutation and associated chronic myeloproliferative disorders was not a major cause of HVOTO and EHPVO in this population.

Background and Aim: Restless leg syndrome (RLS) has recently been shown to be increased in patients with liver cirrhosis (LC). We prospectively studied the prevalence and severity of RLS, and the effect of its presence on the quality of life (QoL) in Indian patients with LC., Methods: Adult patients with stable LC (n = 121; 98 male; median age 47 [range 18-68] years; Child-Pugh class A/B/C 59/39/23), were prospectively enrolled along with a group of healthy, adult controls (n = 121; 84 male; median age 42 [19-70] years). Patients with recent (<4 weeks) worsening were excluded. The subjects underwent an initial screening for RLS, followed by a re-evaluation to confirm the diagnosis, using the International RLS Diagnostic Criteria, and assessment of its severity. All participants underwent QoL assessment., Results: RLS was commoner in LC patients (8/121; 6.6 %) than in controls (1/121; p < 0.05; odds ratio = 8.5 [1.1-69.0]). Presence of RLS showed no association with specific gender (male 7/98, female 1/23), Child-Pugh class (A 5/59, B 1/39 and C 2/23) or cause of liver disease (alcohol 3/32, hepatitis B 1/18, hepatitis C 3/28, and cryptogenic 1/25). RLS severity was moderate (5), severe (2), or very severe (1). Though QoL scores were lower in patients with LC than in controls, those in patients with and without RLS were similar., Conclusion: RLS was commoner in patients with LC than in controls, but did not correlate with liver disease severity and did not adversely influence QoL in LC.

Background: The prevalence of hepatitis D virus (HDV) infection among persons with hepatitis B virus (HBV) infection shows geographic variation and has declined in recent times in several regions. In India, studies during the 1990s showed highly variable anti-HDV prevalence rates among HBV-infected persons; however, data using molecular testing and recent data are not available. We therefore studied the prevalence of HDV infection in HBV-infected patients using tests for anti-HDV and HDV ribonucleic acid (RNA)., Methods: Two cohorts of patients with HBV infection were enrolled (cohort A, n = 150, January to December 2012; cohort B, n = 168, October 2013 to April 2014). Sera from cohort A were tested for IgG anti-HDV using three enzyme immunoassays and those from cohort B for IgG anti-HDV using an enzyme immunoassay and for HDV RNA using a real-time amplification assay., Results: Of the 318 subjects (259 male; mean age 36.9 years), 161 (50.6 %) had chronic hepatitis B, 101 (31.8 %) had cirrhosis, 52 (16.3 %) had acute viral hepatitis, and 4 (1.3 %) had acute liver failure. In cohort A, all specimens tested negative for anti-HDV antibodies using all the three assays. In cohort B, all specimens tested negative for anti-HDV IgG as well as HDV RNA., Conclusion: Our data indicate that HDV infection is uncommon in northern India.

Background: Hepatitis E virus (HEV) infection is highly endemic in India, being the most common cause of acute hepatitis; however, no case of chronic infection has been reported. All the human isolates of HEV from India till date have belonged to genotype 1. In contrast, in non-endemic areas, genotype 3 is the most prevalent, and persistent HEV infection has been reported among solid-organ transplant recipients. Whether persistent infection occurs with genotype 1 HEV is unclear. We therefore looked for evidence of HEV infection among renal transplant recipients with elevated alanine transaminase (ALT)., Methods: Renal transplant recipients receiving immunosuppressive therapy were screened for ALT levels, irrespective of time duration since renal transplant. For those with ALT levels equal to or exceeding 50 IU/mL on at least two occasions ≥3 weeks apart, serum was tested for HEV RNA using a sensitive real-time reverse transcription polymerase chain reaction assay. For those testing positive, HEV genotyping and follow up for duration of viral persistence were planned., Results: Of the 275 patients studied, 49 (17.8 %, 44 male, median age = 39.5 years) had elevated ALT levels (median = 62 [range = 50-477] IU/L). None of these 49 patients had detectable HEV RNA in the serum using an assay with detection sensitivity of 300 copies of RNA/mL of specimen., Conclusion: Our data indicate that persistent HEV infection is an infrequent cause of ALT elevation in Indian renal transplant recipients who are receiving immunosuppressive drugs. This suggests that infection with genotype 1 HEV may have either no or low potential to cause persistent infection.

Background: Autoantibody testing is used to diagnose autoimmune hepatitis (AIH), a cause of chronic liver disease (CLD). However, various autoantibodies are often detectable in patients with CLD due to other causes too. Since data on autoantibody prevalence in Indian patients with CLD are limited, we decided to undertake the current study., Methods: Patients with CLD with a known cause other than AIH and a separate group of patients with CLD in whom no cause could be identified were studied. Indirect immunofluorescence assays were used to detect anti-nuclear antibodies (ANA), anti-smooth muscle antibodies (ASMA) and anti-liver-kidney microsomal antibodies (anti-LKM). Serum dilutions tested were 1:80 for ANA and 1:40 for other autoantibodies., Results: Of the 175 patients with CLD of a known cause, 69 (39 %) had one or more autoantibodies, including ANA in 35 (20 %) patients and ASMA in 44 (25 %) patients. None had anti-LKM. The prevalence rates of any autoantibody, ANA and ASMA were similar in patients with CLD due to alcohol (34 %, 20 %, and 24 %, respectively), HCV infection (43 %, 20 %, and 26 %) and HBV infection (40 %, 18 %, and 25 %). The most common ANA pattern observed was speckled (29/35 patients), followed by nucleolar (5/35) and homogeneous (1/35). The ASMA titers did not exceed 1:80. The antibody prevalence rates were similar in patients with liver cirrhosis and chronic hepatitis, and in those with different disease severity. Serum IgG levels were similar in patients with and without detectable autoantibodies. Patients with no known cause of CLD (n = 50) had similar prevalence rates of autoantibodies, ANA or ASMA., Conclusion: Autoantibodies were detected in a large proportion of patients with CLD, both cryptogenic and with known cause. Detection of autoantibodies in CLD does not necessarily indicate a diagnosis of AIH, and presence of homogenous pattern of ANA may be more relevant. Indiscriminate testing for autoantibodies in patients with CLD, especially those with a known cause, may not be warranted.

Parasitic infestation often present with superficial nodular swelling. Fine needle aspiration cytology plays an important role in prompt diagnosis of the disease. To study the role of FNAC in the diagnosis of parasites presenting as skin or subcutaneous nodules. Total 361 cases of superficial swellings at various sites were subjected to fine needle aspiration cytology. Out of the 361 cases, 35 cases were diagnosed as suggestive of parasitic infestation. These 35 cases form the study group. In 14 cases out of 35 cases, a definitive diagnosis of parasitic infestation was made as parasite or fragments of parasite were seen in the aspirate. In 21 cases, neither parasite nor fragments could be identified on the aspirates and a diagnosis of parasitic inflammation was suggested on the basis of other cytomorphological findings. In 17 of these cases, a biopsy correlation was available, which revealed definitive parasite in 8 cases and the remaining 9 were reported as suggestive of parasitic cyst. The cytological diagnosis was confirmatory in cases where the parasite fragment were identified in the smears. However, in other cases, clear aspirate, presence of eosinophils, macrophages and typical granular dirty background are the features which should prompt the cytologist to the possibility of parasitic infestation.

Objective: To evaluate the demographic profile, high risk factors, fetomaternal outcome and management options in morbidly adherent placenta (MAP)., Study Design: Retrospective analysis., Methodology: Review of 20 case records of women with MAP during year 2001-2006., Results: The mean age and parity of the women was 27.7 ± 4.2 years and 2.5 respectively. 70 % women had previous uterine scar, and similar number had placenta previa. 60 % women presented with antepartum hemorrhage and 20 % with retained placenta. 85 % women underwent hysterectomy with 5 % requiring internal iliac artery ligation, another 5 % partial cystectomy and 15 % bladder repair. Blood loss was between one and nine litres requiring an average of six units whole blood and 4 units FFP. There were six (30 %) maternal deaths. 55 % of the newborns were preterm and the perinatal mortality was 33.3 %., Conclusion: Cesarean section and placenta previa are significant risk factors. MAP is associated with high fetomaternal morbidity and mortality.

Objective: Little is known about cow's milk protein intolerance (CMPI) in India. This study was aimed at finding CMPI cases and determining the role of IgG anti-beta-lactoglobulin antibody in the diagnosis of this condition in India., Methods: From June 2004 to December 2005, 30 children with presumptive diagnosis of CMPI, based on endoscopic rectal or duodenal biopsy showing excess eosinophils and response to milk withdrawal, were enrolled and studied prospectively. Definite diagnosis was made in 20 children on the basis of positive milk challenge. IgG anti-beta-lactoglobulin antibodies were tested in children with CMPI before and after stopping milk and after milk challenge. Antibody levels were also studied in 27 age-matched disease controls and 50 healthy adults., Results: The median age of 20 children (16 boys) with CMPI was 16.5 (6-36) months. Of them, 18 presented with diarrhea (12 bloody) and 2 had rectal bleeding. The presumptive diagnosis was most often (85%) based on colonic or rectal biopsy findings. Rectal biopsy was diagnostic in all 20 cases irrespective of the mode of presentation compared with duodenal biopsy which was diagnostic in 3 cases (p< 0.0001). There was no difference in antibody levels between cases and controls; the antibody level decreased significantly after milk withdrawal (p< 0.005), but did not rise significantly after milk re-challenge., Conclusions: CMPI is a common cause of chronic diarrhea in children in northern India. Sigmoidoscopy and rectal biopsy help in establishing the diagnosis in most cases. IgG anti-lactoglobulin antibody test is not useful in diagnosing CMPI in the Indian setting.

Background: Extra-hepatic portal vein obstruction due to portal vein thrombosis (PVT) is an important cause of portal hypertension in several regions including India. The cause of thrombosis in these patients remains unclear. We studied the frequency of mutations in genes for coagulation factors V and II (prothrombin) in 61 Indian patients with PVT and 49 healthy control subjects., Methods: The presence of factor V Leiden mutation and of G20210A prothrombin gene mutation was determined using polymerase chain reaction followed by restriction fragment length polymorphism. Chi-squared test was used to compare patients and controls., Results: Of the 61 patients (median age 11 years; 47 male) studied, 49 were children. One of 61 (1.6%) patients with PVT was heterozygous for factor V Leiden mutation and none had the G20210 prothrombin gene mutation. The frequencies of these mutations were not different from those in control subjects (2/49 and 0/46, respectively)., Conclusion: Factor V Leiden and G20210 prothrombin gene mutations are infrequent in Indian patients with PVT. Thus, these mutations are unlikely to be responsible for PVT in the Indian population.
