RESUMEN

Introduction: Anaemia is one of the micronutrient deficiency disorders that have global public health implications. The present study aims to determine the association of minimum dietary diversity (MDD) with anaemia among children aged 6-59 months in rural North India. Methods: In Rohtak (a north Indian city), a cross-sectional survey was conducted in 2018-19 (n = 266). Univariate and bivariate analyses were performed. The Chi-square test was used for assessing the significance level during bivariate analysis. Further, multivariable regression analysis was used for determining the factors for anaemia prevalence among children aged 6-59 months. Results: About 62.4% (n = 166) of the children aged 6-59 months were found to have anaemia in the study area. The prevalence of MDD was 35.3% (n = 94). It was found that children with no MDD have a higher prevalence of moderate (42% vs. 25.5%; P < 0.001) and severe (12.8% vs. 8.5%; P < 0.001) anaemia. It was revealed that the children with no MDD had a significantly higher likelihood of being anaemic than children with MDD in model-1 [aOR: 2.09; CI: 1.23, 3.55] and model-3 [aOR: 1.70; CI: 1.01, 3.01]. Children with mothers who never attended school had significantly higher odds for anaemia in reference to those children whose mothers ever attended school in model-2 [aOR: 3.62; CI: 2.07,6.34] and model-3 [aOR: 3.00; CI: 1.62,5.56]. Conclusion: Measures to alleviate under-five anaemia should include empowering and educating women, expanding access to supplementation, fortification programmes, and promoting and raising awareness about feeding diverse foods, while also considering the socioeconomic status.

RESUMEN

Adolescents and young adult comprise a significant proportion of India's population. Although, this group of the population faces serious challenges to their health and well-being. To promote their health and well-being, Centre of Excellence (CoE) at King George's Medical University, Lucknow, India, serves as an advanced care facility for 10-24-year-old adolescents and young adult women. This paper reports the socio-demographic characteristics of, and health services availed to adolescents and young adults who are visiting the CoE in Lucknow, India. A total of 6038 beneficiaries received clinical services during June 2018-March 2022. Out of total clinical services, 38.37% counselling and 37.53% referral services were utilised. Menstruation (46.29%), sexual and reproductive (28.19%), nutrition (5.91%), and mental health (1.67%) related problems were highly reported. The age of beneficiaries is classified into three categories, i.e., 10-14, 15-19, and 20-24 years. Prevalence of overweight was highest among adolescents aged 20-24 years compared to other age groups. Other than nutrition, late-adolescent girls (15-19) faced more health problems than their counterparts. The percentage of beneficiaries decreased significantly during and post the COVID-19 period (<0.001). Therefore, age-specific programs are currently needed, and interventions need to be designed accordingly.

RESUMEN

BACKGROUND: Monitoring ocular morbidity among pediatric patients requires regular follow-up visits. We found that the follow-up rate was poor among children in our setting. Therefore, we intended to assess the effectiveness of 2 interventions-(1) counseling and (2) SMS text messaging and phone calls-to improve the follow-up rates. OBJECTIVE: This study aimed to evaluate the effectiveness of 2 interventions, counseling and SMS and phone calls group, as well as a routine standard care for improving the follow-up rate of pediatric patients. METHODS: A Nonrandomized, quasiexperimental design was used. Children (aged 0-16 years) with ocular conditions requiring at least 3 follow-up visits during the study period were included. A total of 264 participants were equally allocated to the 3 intervention groups of (1) counseling, (2) SMS and phone calls, and (3) routine standard care group. A 20-minute counseling session by a trained counselor with the provision of disease-specific leaflets were given to those in the counseling group. For the second intervention group, parents of children received an SMS text 3 days before and a phone call 1 day before their scheduled follow-up visits. Participants allocated for the routine standard care group were provided with the existing services with no additional counseling and reminders. Participants attending 3 follow-ups within 2 days of the scheduled visit date were considered compliant. The difference in and among the proportion of participants completing all 3 follow-up visits in each group was assessed. RESULTS: The demographic characteristics of the participants were similar across the study groups. Only 3% (8/264) of participants completed all 3 follow-up visits, but overall compliance with the follow-up, as defined by the investigators, was found to be only 0.76% (2/264). There was no statistically significant difference in the proportion of follow-up between the intervention groups. However, the proportion of participants attending the first and second follow-ups, as well as the overall total number of follow-ups, was more in the SMS and phone-call group followed by the counseling group. CONCLUSIONS: We did not find any evidence on the effectiveness of our interventions to improve the follow-up rate. The primary reason could be that this study was conducted during the COVID-19 pandemic. It could also be possible that the intensity of the interventions may have influenced the outcomes. A rigorously designed study during the absence of any lockdown restrictions is warranted to evaluate intervention effectiveness. The study also provides useful insights and highlights the importance of designing and systematically developing interventions for improving the follow-up rate and ensuring a continuum of care to children with visual disabilities in Nepal and similar contexts.

RESUMEN

OBJECTIVE: This study aims to estimate the prevalence of human papillomavirus (HPV) vaccine usage and determine the factors for awareness about HPV vaccine among women in reproductive age group. METHODS: This is a cross-sectional survey under a cervical cancer prevention study. The sample size was 1020 women, aged 15-49 years [550 in Delhi and 470 in Rohtak]. Bivariate analysis and Fisher exact test along with binary logistic regression analysis were used to determine the factors for awareness. RESULT: About 18.0 % [Delhi: 24.2 % and Rohtak: 10.9 %] of the respondents had heard about the vaccine against cervical cancer. The women aged more than 30 years [AOR: 1.35; CI: 0.94, 1.94] were more likely to be aware of cervical cancer vaccine as compare to women of 30 years and less. However, the women from Rohtak [AOR: 0.90; CI: 0.48, 1.66] were less likely to be aware of vaccine against cervical cancer in reference to women aged 30 years and more [AOR: 1.61; CI: 1.01, 2.56] from Delhi. About 0.6 % [Delhi: 1.1 % and Rohtak: 0.0 %] of the respondents had received HPV vaccine. CONCLUSION: Women tend to have limited knowledge about cervical cancer vaccine and immunisation practices. The women's demographic makeup varied significantly between the two sites, i.e , Rohtak and Delhi, which had an impact on how well they understood and utilised the cervical cancer vaccination. It is worth mentioning that none of the women from Rohtak had received the immunisation. The awareness of the cervical cancer vaccine among women from the Rohtak was lower than the Delhi women.

RESUMEN

High ambient temperature is a key public health problem, as it is linked to high heat-related morbidity and mortality. We intended to recognize the characteristics connected to heat vulnerability and the coping practices among Indian urbanites of Angul and Kolkata. In 2020, a cross-sectional design was applied to 500 households (HHs) each in Angul and Kolkata. Information was gathered on various characteristics including sociodemographics, household, exposure, sensitivity, and coping practices regarding heat and summer heat illness history, and these characteristics led to the computation of a heat vulnerability index (HVI). Bivariate and multivariable logistic regression analyses were used with HVI as the outcome variable to identify the determinants of high vulnerability to heat. The results show that some common and some different factors are responsible for determining the heat vulnerability of a household across different cities. For Angul, the factors that influence vulnerability are a greater number of rooms in houses, the use of cooling methods such as air conditioning, having comorbid conditions, the gender of the household head, and distance from nearby a primary health centre (PHC). For Kolkata, the factors are unemployment, income, the number of rooms, sleeping patterns, avoidance of nonvegetarian food, sources of water, comorbidities, and distance from a PHC. The study shows that every city has a different set of variables that influences vulnerability, and each factor should be considered in design plans to mitigate vulnerability to extreme heat.

RESUMEN

INTRODUCTION: Food adequacy and dietary quality in the lactation period are fundamental for maternal and child health. Lactating mothers are vulnerable to malnutrition because of increased physiological demand, monotonous diet, lactogenesis process, and increased nutrient requirements. The micronutrient adequacy especially among women is not ensured in Indian diet. The dual course of gender bias and poverty, along with lack of knowledge about diet quality are significant impediments in maintaining minimum dietary diversity among Indian women. The study aimed to assess the prevalence of minimum dietary diversity and associated factors among lactating women. METHODOLOGY: A community-based cross-sectional study was conducted among 1236 lactating women through a multistage sampling procedure in Haryana state, India. Data were collected in Computer-assisted personal interviewing (CAPI) using a pretested structured interview schedule. Minimum Dietary Diversity for Women by Food and Agriculture Organization (FAO) was used to calculate the minimum dietary diversity. RESULTS: The mean dietary diversity score among lactating women from the ten food groups was 6.35 ± 2.57 and the prevalence of minimum dietary diversity was 77.1%. The complete model revealed that both individual and household factors can explain the variation in dietary diversity intake. Furthermore, the result of model 2 explained that women aged 31 to 35 years (AOR 5.92,95% (1.87-18.77), graduation and above qualified women (AOR 1.98, 95% (0.96-4.09) and lactating women with high knowledge on nutrition (AOR 2.00, 95% (1.34-4.57) were the significant factors promoting minimum dietary diversity. CONCLUSION: Three-fourths of the lactating women reached adequate minimum dietary diversity. Younger age, low educational level, and poor nutritional knowledge were significant constraints to achieving minimum dietary diversity. Further improvement in the minimum dietary diversity among lactating women is very much required. It is also advised that exiting platforms dispersing awareness on nutrition should be supported and strengthened.

RESUMEN

BACKGROUND: The present study aims to estimate the prevalence and determine the factors for cervical cancer screening among women in the reproductive age group in Delhi and Rohtak, India. METHODS: The data were utilized from a survey conducted as part of a larger study to increase the access to cervical cancer screening and care by MAMTA-Health Institute for Mother and Child in collaboration with the Health Departments of Palam, New Delhi, and Rohtak, Haryana between 2015 and 2017. Data pertaining to the socio-economic and demographic information along with the information related to cervical cancer screening were utilized for the present study. The sample size was 1020 women in reproductive age group. Descriptive statistics (percentage and frequency distribution), bivariate analysis along with multivariable analysis were done to represent the results.  The Fisher exact test was used to test the level of significance during bivariate analysis. RESULTS: About 35.2% [Delhi: 44.9% and Rohtak: 23.8%] of the respondents had heard about cervical cancer screening. Further about 3.9% [Delhi-2.9% and Haryana-5.1%] had screened for cervical cancer. Women who had heard about cervical cancer were five times more likely to go for screening [aOR: 5.27; CI: 2.53,10.96]. It was found that women over 30 years of age had 12.04 significantly higher  odds of going for cervical cancer screening in reference to women aged 30 years and less [aOR: 12.04; CI: 3.01,53.20]. Women from households with a monthly income of more than 15000 had 2.98  significantly higher odds of going for cervical cancer screening in reference to women from households with an income of 5000 and less [aOR : 2.98; CI: 1.12,9.09]. CONCLUSION: Findings suggest that awareness about cervical cancer screening test along with its thorough knowledge about its benefits would be an effective intervention to increase the uptake of cervical cancer screening.

RESUMEN

BACKGROUND: Early-stage cervical cancer diagnoses may be the consequence of timely medical care in the presence of symptoms which can be linked to awareness of the symptoms and risk factors. This study aims to determine the knowledge about risk factors and symptoms of cervical cancer and associated factors among women aged 20-49 years. METHODS: Data were utilized from the survey under the intervention "Increasing access to cervical cancer screening and care through the community-centric continuum of care initiative in India" (2015). The sample size was 1,020 women in the age group of 20-49 years. Descriptive statistics, along with bivariate analysis, was done to represent the preliminary results. Multivariable regression analysis was used to represent the estimates. RESULTS: About 40.1% [Delhi: 56.9% and Rohtak: 20.4%] and 45.5% [Delhi: 52.2% and Rohtak: 37.7%] of respondents had good knowledge about risk factors and symptoms of cervical cancer, respectively. Respondents with primary educational status had an 86% significantly higher likelihood for good knowledge about identified risk factors of cervical cancer [ adjusted odds ratio (aOR): 1.86; CI: 1.12-3.10]. Respondents who were married or widowed/divorced/separated had significantly higher odds for good knowledge about identified risk factors and symptoms of cervical cancer in reference to respondents who were never married. Respondents from Rohtak had 72% and 35% significantly higher odds for good knowledge about identified risk factors [aOR:0.28; CI: 0.21,0.39] and symptoms [aOR:0.65; CI: 0.48,0.88] of cervical cancer, respectively, in reference to respondents from Delhi. CONCLUSION: Overall awareness about cervical cancer and Human papillomavirus (HPV) as the causative agent was low, more so in Rohtak. This is extremely worrisome as blocking HPV infection is one of the most effective ways to prevent cervical cancer. Moreover, the knowledge about the risk factors and symptoms of cervical cancer is also inadequate, particularly in women from Rohtak.

RESUMEN

BACKGROUND: The follow-up of pediatric patients ensures regular ocular morbidity monitoring and better treatment outcome. Hiralal Santudevi Pradhan Institute of Ophthalmic Science (Bharatpur Eye Hospital [BEH]) noticed that the follow-up rate was only 22% among its pediatric patients. Several factors like lack of awareness and forgetfulness among patients may contribute to a lower number of follow-up visits. Therefore, BEH decided to find if counseling and reminders through SMS text messaging and phone calls would improve the follow-up rates. OBJECTIVE: This study aims to evaluate the impact of interventions like counseling and reminder SMS text messaging and phone calls in improving the follow-up rate of pediatric patients. METHODS: This is a public health intervention study being conducted using quantitative analysis. All children (0-16 years) with ocular conditions requiring at least 3 follow-up visits in the study period will be included. In all, 264 participants will be allocated to 3 groups: routine standard care, counseling, and reminders with SMS text messaging and phone calls. In counseling, patients will take part in 20-minute counseling sessions with trained counselors at each visit, and information leaflets will be provided to them. In the reminder SMS text messaging and phone call group, patients will receive an SMS text message 3 days prior and a phone call 1 day prior to their scheduled visits. Patients attending within 2 days of the scheduled date will be considered compliant to follow-up. The proportion of patients completing all the follow-up visits in each group will be assessed. Informed consent will be taken from parents and children. Univariate and multivariate analyses will be conducted. RESULTS: The ethical approval for this study has been obtained from the Ethical Review Board (ERB) of Nepal Health Research Council (ERB protocol registration #761/2020 P). The data collection was initiated on January, 24, 2021, but due to the COVID-19 pandemic, as of September 2021, we have only been able to enroll 154 of the planned 264 participants (58.3% of the sample size). CONCLUSIONS: This study will reliably document not only the factors associated with follow-up rate through an intervention package (counseling and reminders through SMS text messaging and phone calls) but also the cost effectiveness of the intervention package, which can be applied in all the departments of the hospital.

RESUMEN

Extreme heat and heat waves have been established as disasters which can lead to a great loss of life. Several studies over the years, both within and outside of India, have shown how extreme heat events lead to an overall increase in mortality. However, the impact of extreme heat, similar to other disasters, depends upon the vulnerability of the population. This study aims to assess the extreme heat vulnerability of the population of four cities with different characteristics across India. This cross-sectional study included 500 households from each city across the urban localities (both slum and non-slum) of Ongole in Andhra Pradesh, Karimnagar in Telangana, Kolkata in West Bengal and Angul in Odisha. Twenty-one indicators were used to construct a household vulnerability index to understand the vulnerability of the cities. The results have shown that the majority of the households fell under moderate to high vulnerability level across all the cities. Angul and Kolkata were found to be more highly vulnerable as compared to Ongole and Karimnagar. Further analysis also revealed that household vulnerability is more significantly related to adaptive capacity than sensitivity and exposure. Heat Vulnerability Index can help in identifying the vulnerable population and scaling up adaptive practices.

RESUMEN

OBJECTIVE: To study the prevalence of Group A beta haemolytic Streptococcus in patients with acute pharyngitis and correlation of Modified Centor Score and Rapid Antigen Detection Test. METHODS: The multi-centre, prospective, cross-sectional study was conducted in 8 major cities of Pakistan between June 2012 and February 2013, and comprised patients presenting with acute pharyngitis. The subjects were above 3 years of age presenting to primary care physician with sore throat, temperature over 100.4 degrees F, tonsillar exudates and/or cervical adenopathy (duration of symptoms < 14 days). They were scored using Modified Centor Score and were tested with Rapid Antigen Detection Test for Group A beta haemolytic Streptococcus. SPSS 19 was used for statistical analysis. RESULTS: Of the 5140 patients, 1299 (25.3%) tested positive, for RADT Group A beta haemolytic Streptococcus in acute pharyngitis. There was no significant difference across different age groups (p < 0.08). There was a strong correlation between Modified Centor Score and Rapid Antigen Detection Test results (p < 0.001). Of the patients with positive result, 3 (0.4%) had a Modified Centor Score < or = 0; 23 (1.8%) had score of 1; 152 (11.7%) had score of 2; 511 (39.3%) had score of 3; and 609 (46.9%) had Centor score of > or = 4. CONCLUSION: The prevalence of Group A beta haemolytic Streptococcus as a cause of acute pharyngitis was 25.3%. Modified Centor Score had a strong positive correlation with Rapid Antigen Detection Test in identifying Group A beta haemolytic Streptococcus as a cause of acute pharyngitis.

RESUMEN

BACKGROUND: Verbal autopsy (VA) has been proposed to determine the cause of death (COD) distributions in settings where most deaths occur without medical attention or certification. We develop performance criteria for VA-based COD systems and apply these to the Registrar General of India's ongoing, nationally-representative Indian Million Death Study (MDS). METHODS: Performance criteria include a low ill-defined proportion of deaths before old age; reproducibility, including consistency of COD distributions with independent resampling; differences in COD distribution of hospital, home, urban or rural deaths; age-, sex- and time-specific plausibility of specific diseases; stability and repeatability of dual physician coding; and the ability of the mortality classification system to capture a wide range of conditions. RESULTS: The introduction of the MDS in India reduced the proportion of ill-defined deaths before age 70 years from 13% to 4%. The cause-specific mortality fractions (CSMFs) at ages 5 to 69 years for independently resampled deaths and the MDS were very similar across 19 disease categories. By contrast, CSMFs at these ages differed between hospital and home deaths and between urban and rural deaths. Thus, reliance mostly on urban or hospital data can distort national estimates of CODs. Age-, sex- and time-specific patterns for various diseases were plausible. Initial physician agreement on COD occurred about two-thirds of the time. The MDS COD classification system was able to capture more eligible records than alternative classification systems. By these metrics, the Indian MDS performs well for deaths prior to age 70 years. The key implication for low- and middle-income countries where medical certification of death remains uncommon is to implement COD surveys that randomly sample all deaths, use simple but high-quality field work with built-in resampling, and use electronic rather than paper systems to expedite field work and coding. CONCLUSIONS: Simple criteria can evaluate the performance of VA-based COD systems. Despite the misclassification of VA, the MDS demonstrates that national surveys of CODs using VA are an order of magnitude better than the limited COD data previously available.

RESUMEN

BACKGROUND: Computer-coded verbal autopsy (CCVA) methods to assign causes of death (CODs) for medically unattended deaths have been proposed as an alternative to physician-certified verbal autopsy (PCVA). We conducted a systematic review of 19 published comparison studies (from 684 evaluated), most of which used hospital-based deaths as the reference standard. We assessed the performance of PCVA and five CCVA methods: Random Forest, Tariff, InterVA, King-Lu, and Simplified Symptom Pattern. METHODS: The reviewed studies assessed methods' performance through various metrics: sensitivity, specificity, and chance-corrected concordance for coding individual deaths, and cause-specific mortality fraction (CSMF) error and CSMF accuracy at the population level. These results were summarized into means, medians, and ranges. RESULTS: The 19 studies ranged from 200 to 50,000 deaths per study (total over 116,000 deaths). Sensitivity of PCVA versus hospital-assigned COD varied widely by cause, but showed consistently high specificity. PCVA and CCVA methods had an overall chance-corrected concordance of about 50% or lower, across all ages and CODs. At the population level, the relative CSMF error between PCVA and hospital-based deaths indicated good performance for most CODs. Random Forest had the best CSMF accuracy performance, followed closely by PCVA and the other CCVA methods, but with lower values for InterVA-3. CONCLUSIONS: There is no single best-performing coding method for verbal autopsies across various studies and metrics. There is little current justification for CCVA to replace PCVA, particularly as physician diagnosis remains the worldwide standard for clinical diagnosis on live patients. Further assessments and large accessible datasets on which to train and test combinations of methods are required, particularly for rural deaths without medical attention.

RESUMEN

BACKGROUND: Physician-coded verbal autopsy (PCVA) is the most widely used method to determine causes of death (CODs) in countries where medical certification of death is uncommon. Computer-coded verbal autopsy (CCVA) methods have been proposed as a faster and cheaper alternative to PCVA, though they have not been widely compared to PCVA or to each other. METHODS: We compared the performance of open-source random forest, open-source tariff method, InterVA-4, and the King-Lu method to PCVA on five datasets comprising over 24,000 verbal autopsies from low- and middle-income countries. Metrics to assess performance were positive predictive value and partial chance-corrected concordance at the individual level, and cause-specific mortality fraction accuracy and cause-specific mortality fraction error at the population level. RESULTS: The positive predictive value for the most probable COD predicted by the four CCVA methods averaged about 43% to 44% across the datasets. The average positive predictive value improved for the top three most probable CODs, with greater improvements for open-source random forest (69%) and open-source tariff method (68%) than for InterVA-4 (62%). The average partial chance-corrected concordance for the most probable COD predicted by the open-source random forest, open-source tariff method and InterVA-4 were 41%, 40% and 41%, respectively, with better results for the top three most probable CODs. Performance generally improved with larger datasets. At the population level, the King-Lu method had the highest average cause-specific mortality fraction accuracy across all five datasets (91%), followed by InterVA-4 (72% across three datasets), open-source random forest (71%) and open-source tariff method (54%). CONCLUSIONS: On an individual level, no single method was able to replicate the physician assignment of COD more than about half the time. At the population level, the King-Lu method was the best method to estimate cause-specific mortality fractions, though it does not assign individual CODs. Future testing should focus on combining different computer-coded verbal autopsy tools, paired with PCVA strengths. This includes using open-source tools applied to larger and varied datasets (especially those including a random sample of deaths drawn from the population), so as to establish the performance for age- and sex-specific CODs.

RESUMEN

OBJECTIVE: To evaluate platelet count/ splenic size ratio as a non-invasive parameter to predict the presence and absence of esophageal varices in patients with cirrhosis of liver. DESIGN: An observational, cross- sectional study. PLACE AND DURATION OF STUDY: The medical units of the Civil Hospital, Karachi, between October 2003 and October 2004. PATIENTS AND METHODS: During one year of study, one hundred and thirteen (113) patients with cirrhosis of liver were studied. These patients were evaluated for the cause of chronic liver disease, ascites and splenic size by abdominal ultrasound, serum proteins and albumin, prothrombin time, complete blood count including platelet count and liver functions test. All the patients had upper GI endoscopy to determine if they had esophageal varices and were classified according to Child s-Pugh classification. It was determined if the platelet count/ splenic size ratio between the two groups was different and its relation to the presence or absence of esophageal varices was noted. RESULTS: Of the one hundred and thirteen (113) patients included in the study, 35(31%) were female and 78(69%) male. The mean age of these patients was 37.1(+/- 14.85) years. Thirty-eight patients had HBsAg, 59 had anti-HCV antibodies, 8 patients had both HbsAg and anti-HCV antibodies and the cause of cirrhosis in 8 patients was indeterminate. Fifty patients had ascites. Of 113 patients, 15(13.27%) were classified as Child s Pugh class A, 68(60.18%) in class B and 30(26.55%) in class C. Sixty-six (58.4%) patients had esophageal varices on upper GI endoscopy while 47(41.6%) had no endoscopic evidence of esophageal varices. The ratio between platelet count/ splenic size was found to be significantly (p < 0.001) different between patients who had esophageal varices and those who did not. CONCLUSION: Platelet count/splenic size ratio is an important and an independent parameter associated with the presence of esophageal varices.

RESUMEN

OBJECTIVE: To determine the frequency of hepatorenal syndrome in patients with chronic liver disease and ascites. DESIGN: A cross-sectional study. PLACE AND DURATION OF STUDY: From July 2001 to March 2002 at Civil Hospital, Karachi. PATIENTS AND METHODS: The study included 240 patients who were admitted in the Medical Wards of Civil Hospital, Karachi, during the study period. The subjects were diagnosed as having chronic liver disease and all of them had ascites. All the patients with renal dysfunction were identified and were worked up for hepatorenal syndrome and other causes of renal dysfunction. RESULTS: Of two hundred and forty (240) patients enrolled in the study, 148 were male (61.7%) and 92 were female (38.3%). Seventy-six (76) patients (31.6%) were found to have renal impairment as diagnosed by serum creatinine level of 1.5 mEq/L or greater. Six (6) patients showed improvement in their serum creatinine level (below 1.5 mg/dL) after receiving 1.5 liter of normal saline infusion and diuretic withdrawal. Eleven (11) patients were diagnosed to have primary renal disease based on urine analysis, urinary protein excretion and ultrasound examination. Six (6) patients were diagnosed to have renal dysfunction secondary to analgesic nephropathy and in seventeen (17) patients renal dysfunction was secondary to spontaneous bacterial peritonitis. The remaining 36 (47.4%) patients with renal dysfunction were diagnosed as suffering from hepatorenal syndrome based on the diagnostic criteria. This represents the frequency of 15% among patients with chronic liver disease and ascites. CONCLUSION: Hepatorenal syndrome is common complication in patients with cirrhosis and ascites. It was the most common cause of renal impairment in this series followed by other causes like spontaneous bacterial peritonitis, primary renal disease, analgesic nephropathy and hypovolemia.
