Immunogenicity and safety of quadrivalent and 9-valent human papillomavirus vaccines in Indian clinical trial participants.

The quadrivalent human papillomavirus (qHPV; HPV6/11/16/18) and 9-valent HPV (9vHPV; HPV6/11/16/18/31/33/45/52/58) vaccines have demonstrated efficacy, immunogenicity, and safety in international clinical trials. We report outcomes from three completed clinical trials in India: a single-arm study (V501-029 [NCT00380367]) in Indian girls (aged 9-15 years;  = 110) evaluating qHPV vaccine immunogenicity and safety; a subgroup analysis (n = 225) of Indian girls/boys (9-15 years) and women (16-26 years) from a global study (V503-002 [NCT00943722]) evaluating 9vHPV vaccine immunogenicity and safety; and a qHPV vaccine post-marketing safety surveillance study (V501-125) in Indian females (aged 9-45 years;  = 188) vaccinated during routine care. In V501-029 and V503-002, HPV vaccines were administered as 3 doses (Day 1, Month 2, Month 6).

The impact and cost-effectiveness of 9-valent human papillomavirus vaccine in adolescent females in Hong Kong.

Introduction: In Hong Kong (HK), a single-cohort vaccination program for 10-12-year-old girls with the 9-valent human papillomavirus (HPV) vaccine (9vHPV; types 6/11/16/18/31/33/45/52/58) has been launched. This study assessed the public health impact and cost-effectiveness of implementing routine 9vHPV vaccination (12-year-olds) with or without catch-up 9vHPV vaccination (13-18-year-olds) in HK.

Methods: The health impact and costs of implementing routine 9vHPV vaccination with or without catch-up vaccination over a 100-year time horizon were evaluated using a validated HPV-type transmission dynamic model adapted to the HK population; analyses were performed from a healthcare payer perspective.

Incremental healthcare resource utilization and costs for patients with cervical, vaginal, vulvar, anal, and oropharyngeal cancer in the United States.

Introduction: Human papillomavirus (HPV) cause cancers in a variety of anatomic sites presenting at various stages of disease. Current economic assessments rely on HPV-related cancer cost estimates from data prior to the launch of the nonavalent HPV vaccine (2014). The goal of the present study was to assess and describe the current direct medical care burden of HPV-related cancers in the US.

Systematic literature review of cross-protective effect of HPV vaccines based on data from randomized clinical trials and real-world evidence.

Background: The extent of cross-protection provided by currently licensed bivalent and quadrivalent HPV vaccines versus direct protection against HPV 31-, 33-, 45-, 52-, and 58-related disease is debated. A systematic literature review was conducted to establish the duration and magnitude of cross-protection in interventional and observational studies.

Methods: PubMed and Embase databases were searched to identify randomized controlled trials (RCT) and observational studies published between 2008 and 2019 reporting on efficacy and effectiveness of HPV vaccines in women against non-vaccine types 31, 33, 45, 52, 58, and 6 and 11 (non-bivalent types).

Systematic literature review of neutralizing antibody immune responses to non-vaccine targeted high-risk HPV types induced by the bivalent and the quadrivalent vaccines.

Introduction: Studies on the cross-protective effect of HPV bivalent and quadrivalent vaccines demonstrated inconsistent findings against additional HPV types covered by the nonavalent vaccine. The objective of this study was to conduct a systematic literature review to assess the consistency and durability of the cross-protective neutralizing antibody immune responses of the currently licensed bivalent and quadrivalent vaccines to non-vaccine HPV types targeted by the nonavalent vaccine (HPV 6, 11, 31, 33, 45, 52, and 58).

Methods: PubMed and EMBASE databases were searched from 2008 to 2019 to identify studies reporting antibody/immune response after vaccination with either the bivalent, quadrivalent, or nonavalent vaccine.

The clinical and economic benefits of school-based quadrivalent HPV vaccination in Singapore.

Objective: To investigate the clinical and economic impacts of school-based administration of the quadrivalent HPV vaccine.

Methods: A retrospective health-economic analysis was conducted using data collected in Singapore between 2004 and 2005. A dynamic transmission model was adapted for universal vaccination that provided 80% coverage among students aged 11-12 years.

Immunogenicity and safety of the pentavalent human-bovine (WC3) reassortant rotavirus vaccine (PRV) in Indian infants.

Objective: To evaluate the immunogenicity and safety of a pentavalent rotavirus vaccine (PRV) in Indian infants.

Study Design: Open-label, single-arm multicentric study.

Setting: Hospital facilities (out patients):

Subjects: One hundred and ten (110) healthy Indian infants were enrolled between the ages of 6 weeks and 12 weeks.

Liver function tests and their interpretation.

Liver function tests (LFT) are a helpful screening tool, which are an effective modality to detect hepatic dysfunction. Since the liver performs a variety of functions so no single test is sufficient to provide complete estimate of function of liver. Often clinicians are faced with reports that do not tally with the clinical condition of the patient and they face difficulty in interpreting the LFT.

Congenital intrahepatic porto-systemic venous shunt with galactosemia.

We report a 51-day-old infant with congenital intrahepatic porto-systemic venous shunt associated with galactosemia, who presented with cholestatic jaundice. He was treated with ursodeoxycholic acid, calcium supplements and galactose-free diet. The child was asymptomatic six weeks later.

Mitochondrial neuro-gastrointestinal encephalopathy syndrome.

Mitochondrial neurogastrointestinal encephalomyopathy is a rare disorder affecting the pediatric age group with a heterogeneous multisystem involvement. We happen to manage a young child with symptoms of constipation since infancy along with cachexia, seizures and peripheral neuropathy. The child later went into encephalopathy preterminally.

Pancytopenia in a child associated with hepatitis A infection.

Pancytopenia is a very rare condition associated with hepatitis A infection. We managed a 12 year old boy who had hepatitis A infection with anemia. His hemogram and bone marrow examination were suggestive of pancytopenia.
