Dietary habits and physical activity patterns in relation to nutritional status among school-aged children in Pakistan: A cross-sectional study.

Background: Childhood malnutrition remains a significant public health problem impacting the physical and mental growth if school aged children, particularly in limited-resource countries. Objective: The study objective was to assess levels of physical activity, patterns of screen time (S.T.), the relationship between physical activity and screen time patterns, and how these factors affect growth status (adjusting for socioeconomic status). Methodology: A cross-sectional study included 3,834 children between 6-14 years attending pre-selected schools. Teachers, students, and parents were invited to fill out a standardized questionnaire, and Body Mass Index (BMI) was calculated using Center for disease control (CDC) centile charts. A Chi-square was performed to see the possible association between any height and weight abnormalities and all possible risk factors. Multivariate logistic regression was applied to see the effect of variables significantly associated with univariate analysis. Results: Approximately 2,447 (63.8%) children were between 11-14 years old and 1,387 (36.2%) were between 4-10 years old. The mean height was 143.71 ± 16.51 centimetres, the mean weight was 36.5 ± 12.9 kilogram, and the mean BMI was 17.16 ± 3.52. Multivariate logistic regression status and junk food combined affected stunting socioeconomic status was significantly associated with being underweight p = 0.001. Conclusion: Childhood obesity and stunting remain significant problems in Pakistani school-going children. These are significantly associated with poverty, a lack of physical activity opportunities, and available food quality.

Iatrogenic post biopsy hemobilia with pseudoaneurysm.

Hemobilia is defined as bleeding into the biliary tree from an abnormal communication between a blood vessel and bile duct. It is an uncommon cause of upper gastrointestinal hemorrhage and iatrogenic most of the times. We report a case of hemobilia secondary to percutaneous liver biopsy presenting with classical Quincke's triad in a young lady which was treated with combined biliary balloon sweep thrombectomy and transarterial embolization for complete resolution of symptoms.

Time for change: conventional interferon regimes should not be the standard of care for management of Pakistani genotype-3 in chronic hepatitis C.

The aim of the present study was to determine the efficacy and side effect profile of conventional interferon alpha-2b plus ribavirin for treating chronic hepatitis C genotype-3 infections in Pakistan. The study was conducted on treating 220 treatment-naïve individuals at KRL Hospital with conventional interferon given for 6 months. Both the response and side effects were analyzed using simple descriptive statistics. Out of total cohort, 84.92% (169 out of 199) achieved end of treatment response (ETR) while 63.31% (126 out of 199) achieved sustained virological response (SVR). Leukopenia, gastrointestinal and miscellaneous systemic complaints were the most common adverse effects. In the context of a low ETR and SVR but a similar side effect profile as that of pegylated regimes, conventional therapy needs to be replaced with peg-interferon as the treatment of choice.

Occult HCV or delayed viral clearance from lymphocytes of Chronic HCV genotype 3 patients after interferon therapy.

BACKGROUND: A recently discovered occult HCV entity reported by various investigators seems to be highly controversial. Especially, the clinical significance of these findings remains uncertain. For optimal outcome of antiviral therapy, investigation of occult HCV needs a broad-based probe in order to investigate the results of viral therapy and its host/viral interaction. The current study was aimed at determining the prevalence of occult HCV in peripheral blood lymphocytes of predominantly genotype 3 HCV-infected patients after completion of antiviral therapy and to investigate long term outcomes in the presence or absence of PBMC positivity. METHOD: A total of 151 chronic, antiHCV and serum RNA-positive patients were enrolled in the study. Patients with a complete virological response at the end of treatment were screened for the presence of viral RNA in their PBMCs and were followed for up to one year for the presence of serum and PBMC viral genomic RNA. RESULTS: Out of 151 patients, 104 (70%) responded to the prescribed interferon treatment and showed viral-clearance from serum. These were screened for the presence of genomic RNA in their PBMCs. Sixteen samples were PBMC-positive for viral RNA at the end of treatment (EOT). All these patients had also cleared the virus from peripheral blood cells after the 6-12 month follow-up study. CONCLUSION: True occult hepatitis C virus does not exist in our cohort. Residual viremia at the EOT stage merely reflects a difference in viral kinetics in various compartments that remains a target of immune response even after the end of antiviral therapy and is eventually cleared out at the sustained viral response (SVR).

Response rates to standard interferon treatment in HCV genotype 3a.

BACKGROUND: Chronic Hepatitis C infection infects almost 130 to 170 million or approximately 2.2-3% of world's population. HCV is one of the main causes of chronic liver disease leading to progressive liver injury, fibrosis, cirrhosis and liver cancer. It is also one of the leading indications for liver transplantation worldwide. The objective of the study was to determine the response of treatment with standard Interferon and Ribazole in treatment naïve Hepatitis C infected patients. METHODS: This quasi-experimental study was carried out at the Department of Medicine, KRL General Hospital Islamabad, from January 2003 to January 2005. A total of 250 patients were enrolled in this descriptive study. All patients were anti HCV positive, PCR positive for HCV RNA and had 3a genotype. A non-probability purposive sampling technique was applied to collect data. After taking a written and informed consent; specially designed performa containing the patient profile, family transmission, and baseline laboratory values was filled. Patients were treated with a set protocol of Interferon plus Ribavarin therapy (IFN alpha 2a, 3 mIU thrice weekly for 24 weeks plus Ribavarin 1,000 to 1,200 mg/day) for six months. Chi-Square tests were used to analyse the data. Primary end point was a sustained virological response (SVR) that is response assessed after six months of completion of treatment. RESULTS: Response rates to standard Interferon plus Ribazole therapy were studied over two years period. Out of the total of 250 patients, 60 patients were excluded; as 30 patients did not meet inclusion criteria, 23 patients were lost to follow. Seven patients declined treatment. Out of the 190 patients, 155 (81.6%) achieved End of Treatment Complete Response (EOTCR) whereas 35 (18.4%) were nonresponders (NR). These 155 patients, who showed complete response were followed for six months after the treatment to assess sustained viral response, which was seen in 112 (72.25%) patients whereas 43 (27.7%) were relapsers. Response rates were co-related with gender, baseline ALT and necro-inflammatory stage assessed by liver biopsy, probable risk factors and family history. CONCLUSION: Management of Hepatitis C with genotype 3a, with standard Interferon and Ribazole for six months showed lower SVR compared to that reported in previous international and local data.
