Determinants of severity among hospitalised COVID-19 patients: Hospital-based case-control study, India, 2020.

BACKGROUND: Risk factors for the development of severe COVID-19 disease and death have been widely reported across several studies. Knowledge about the determinants of severe disease and mortality in the Indian context can guide early clinical management. METHODS: We conducted a hospital-based case control study across nine sites in India to identify the determinants of severe and critical COVID-19 disease. FINDINGS: We identified age above 60 years, duration before admission >5 days, chronic kidney disease, leucocytosis, prothrombin time > 14 sec, serum ferritin >250 ng/mL, d-dimer >0.5 ng/mL, pro-calcitonin >0.15 µg/L, fibrin degradation products >5 µg/mL, C-reactive protein >5 mg/L, lactate dehydrogenase >150 U/L, interleukin-6 >25 pg/mL, NLR ≥3, and deranged liver function, renal function and serum electrolytes as significant factors associated with severe COVID-19 disease. INTERPRETATION: We have identified a set of parameters that can help in characterising severe COVID-19 cases in India. These parameters are part of routinely available investigations within Indian hospital settings, both public and private. Study findings have the potential to inform clinical management protocols and identify patients at high risk of severe outcomes at an early stage.

Reasons for the delay in the initiation of treatment and initial default among drug-resistant tuberculosis patients in Ahmedabad corporation area.

The emergence of drug-resistant tuberculosis (DR-TB) has become a significant health problem in India. Delays in diagnosis and treatment initiation are frequently observed among patients with DR-TB, resulting in an increased risk of disease complications and high mortality and pretreatment lost to follow-up rates. To understand the factors associated with delays between the diagnosis and treatment, the study was carried out in Ahmedabad Municipal Corporation Area. A total of 177 DR-TB patients diagnosed in the year 2014 who had a delay in the initiation of treatment, and 23 initial defaulters were studied using a structured questionnaire. Fifty-four DOTS providers were also interviewed. Of 177 patients, 62.15% initiated treatment between 7 and 15 days and nearly 12% of them started the treatment after a month. The median duration of delay was 12 days (range: 8-144 days and interquartile range: 9-20 days). The most common reason for the delay in the initiation and initial default was the social and personal factors (48.80%), and in 34 (20%) of the patients, the delay was attributed to the effect of the previous treatment.

Epidemic investigation of the jaundice outbreak in girdharnagar, ahmedabad, gujarat, India, 2008.

BACKGROUND: Since 1976, seven outbreaks of hepatitis E occurred in Ahmedabad. Clusters of jaundice cases were reported on June 19, 2008, by a civic center, Girdharnagar ward, Ahmedabad. OBJECTIVES: THE OBJECTIVES WERE AS FOLLOWS: (1) to identify the etiological agent, source of outbreak, and mode of transmission; (2) to propose a control measure based on the outbreak investigation. MATERIALS AND METHODS: We defined a case as an acute illness with (a) a discrete onset of symptoms and (b) jaundice or elevated serum aminotransferase levels, from March to September 2008 in the households of the Girdharnagar ward. We collected data through a door-to-door survey and hospital records. We described the outbreak in terms of time, place, and person. We collected laboratory investigation reports of case patients admitted to the civil hospital. To test our hypothesis we conducted a retrospective cohort study to find out the relative risk for hepatitis. We conducted environment investigation to find out the source of contamination of water supply. RESULTS: A total 233 case patients of hepatitis were identified with the attack rate of 10.9/1000 population. Cases were reported in all the age groups with a higher attack rate in the age group of 20-29 years (18.5/1000). Out of 17 case patients, 16 were positive for the hepatitis E IgM antibody. The attack rate was two times more among those who were exposed to the leaking pipeline than the non-exposed (RR=2.3, 95% CI 1.76, 2.98). Environmental investigation also confirmed the sewage contamination of drinking water in the distribution system. CONCLUSION: The outbreak was due to hepatitis E virus. We recommended a temporary alternative water supply, repair of the leakages, and water quality surveillance.

Effectiveness of Different Models of DOTS Providers under RNTCP in Ahmedabad City, Gujarat.

BACKGROUND: The most effective DOTS provider will be the one who is accessible, acceptable to the patient, and accountable to the health system. OBJECTIVES: The objective was to assess the effectiveness of the different types of DOTS providers functioning under Revised National Tuberculosis Control Programme (RNTCP). MATERIALS AND METHODS: Atotal of 200 patients, treated under RNTCP during September to December 2004, were selected for the study. RESULTS: A total of 105 and 95 patients were under the supervision of tuberculosis health visitors (TBHVs) and non-TBHVs, respectively. During the intensive phase, around 95% of the patients took the medicine under the direct observation in both the groups. Supervision of the first dose of treatment in a week during the continuation phase was significantly better with the TBHV (94.74%) as compared to the non-TBHV (79.31%). However, there was no significant difference in the cure and the completed rate which was 76.19% with the TBHV and 86.13% with the non-TBHV. CONCLUSION: The available community workforce could be involved in supervising the intermittent short course chemotherapy.

A case of melanoma in xeroderma pigmentosum.

Xeroderma pigmentosum (XP) was first described in 1874 by Hebra and Kaposi. [1] It is a rare autosomal recessive disorder characterized by photosensitivity, pigmentary changes, premature skin aging, and malignant tumor development due to cellular hypersensitivity to ultraviolet radiation resulting from a defect in DNA repair. The basic defect in XP is in nucleotide excision repair (NER), leading to deficient repair of damaged DNA. A 12-year-old boy presented with a large growth over the right side of the forehead. The lesion was first noticed before two years as a 2 x 2 cm 2 mass. It was slowly growing and attained the present size of 10 x 8 x 7 cm 3 . The surface showed ulceration with areas of hemorrhage and blackish pigmentation. Also, the patient had hyperpigmented macules over the skin since early childhood. The macules appeared initially over the face and later developed over the other areas of the body. The macules were more over the sun exposed areas. He also had photophobia and both eyes showed corneal opacities. Histopathological examination of the excised growth showed features consistent with melanoma. This case is being presented because of its rare association with xeroderma pigmentosum patients in India.

Study of incidence of measles and vaccination coverage in Ahmedabad urban slums.

Measles incidence and vaccination coverage survey was carried out in Ahmedabad urban slums in February 2000. A total of 3073 children between 9 to 59 months were studied. The incidence rate of measles was 11.2% (95% C.I-10.04-12.36). Measles vaccination coverage was only 59.88%. There was no gender difference in vaccine coverage or measles incidence rate. Diarrhoea was the most common complication observed among both vaccinated and unvaccinated children and it was significantly more among unvaccinated children. Among 1840 vaccinated children only 529 (28.75%) children received vitamin A along with measles vaccination.

Prevalence of tuberculosis infection among children in slums of Ahmedabad.

Children below 15 yrs. of age without BCG scar were chosen for the tuberculin testing. Total 210 children were tested in 30 selected clusters (7 children in each cluster). Median age of the surveyed children was 6.33. Prevalence of infection in children was found to be 30.4% as 64 children out of 210 showed positive result (had induration > or = 10mm in size). Average ARI in the 0-14 yrs of age group was 5.4%. Tuberculosis is still one of the commonest problems in the urban slums. It is important to evaluate the epidemiology of tuberculosis in the changing face of century.
