Rampant use of antibiotics making pneumonia a killer
Rampant use of antibiotics making pneumonia a killer

NAGPUR: More incidences of a disease generally equip doctors to manage it better. However, it is the opposite in case of pneumonia, especially the one acquired at the hospitals. Doctors blame indiscriminate use of antibiotics, which has made the pathogens causing this disease more resistant, for making this condition a potentially fatal one.
These were among the many topics discussed during a symposium and clinical meeting of Academy of Medical Sciences on pneumonia held ahead of the World Pneumonia Day that falls on November 9. While Dr PP Joshi and Dr Amol Sagdeo presented some interesting cases, Dr Ravindra Sarnaik, Dr Sanjeev Mehta, Dr Shrinivas Samavedam, Dr Yagnesh Thakkar and Dr Nainesh Patel spoke about the various aspects of managing the disease.
President of AMS Dr Rajan Barokar said other than the known viral originated pneumonia, bacterial and fungal pneumonia is increasingly being reported. "Managing pneumonia and its higher form - acute respiratory distress syndrome (ARDS) - is a challenge for the critical care team," he said. Agreeing with this, Dr Chandrashekhar Cham, secretary of AMS, added that secondary infections of this kind acquired at hospitals are emerging as big killers in ICUs. Dr Sarnaik said with many ailments coexisting, the treatment gets more complicated and longer.
Dr Samavedam informed that 40 per cent patients visiting OPD have respiratory infections while 15 per cent have pneumonia. "A lot of cases do not even get reported as they occur at places where medical services may not be well developed," he said. He warned that parents must be cautious when children have fever that persists for more than two days or is acquired after returning from a holiday or after consuming outside food.
Dr Mehta gave the example of France where government rewards the doctors who give least number of antibiotics and make the patients aware about their misuse. "The pathogens that cause hospital acquired infections are immune to many of the common antibiotics. This has given rise to stronger microbes that are lurking around the hospital. Instead of trying different medications, doctors must send the cultures for laboratory tests to decide the course of drugs," said Dr Thakkar.
Dr Patel spoke of a newly emerging form of pneumonia that has resulted from high resistance among the pathogens called health care associated infections. "This means that the disease, even if acquired outside the hospital or in the community, becomes difficult to treat due to resistance from the organisms causing them," he explained.
Dr SK Deshpande blamed lack of hygiene and overcrowded living spaces for this phenomenon. "Urban slums and a general apathy towards cleanliness have made this situation so bad," he said.

Zinc plus antibiotics saves lives of children with pneumonia, study finds
By: Formulary staff
Zinc used in addition to antibiotics significantly reduced mortality in children ages 6 months to 59 months with severe pneumonia when compared with antibiotics alone, according to the findings of a recent study done in Uganda.
The study, published online February 8 in BMC Medicine, also indicated that the adjunct therapy had a greater effect among HIV-infected children than those who were not infected with HIV.
The double-blind, randomized, placebo-controlled study was led by Maheswari G. Srinivasan, from the Department of Pediatrics and Child Health at the School of Medicine, in Uganda. Researchers enrolled 352 children, aged 6 months to 59 months, who were admitted to the Mulago Hospital pediatric emergency ward with severe pneumonia between September 2006 and March 2007.
"There are 2 key findings in this study: overall, zinc supplementation in these children significantly decreased case fatality, but did not reduce the time to normalization of the parameters for disease severity," the authors stated, noting that these findings come from the secondary objective rather than the primary objectives, which were to assess the effect of zinc as an adjunct therapy on time to normalization of respiratory rate, temperature, and oxygen saturation.
The investigators randomly assigned the children to receive standard antibiotic therapy plus zinc (10 mg for children aged under 12 months; 20 mg for children 12 months and older) or standard antibiotic therapy plus placebo daily. The children were assessed every 6 hours for the first 48 hours and then every 12 hours for 7 days of treatment.
The investigators found no evidence that zinc decreased length of time to recovery. They did, however, note the number of deaths was lower among the children who were treated with zinc (4.0% vs 11.9%; RR=0.33; 95% CI, 0.15-0.76).
In addition, the researchers noted that the effect of zinc supplementation appeared stronger among children infected with HIV. There were more deaths among HIV-positive children assigned to placebo compared with those who received zinc (25.9% vs 0%; RR=0.1; 95% CI, 0.0-1.0).
Among those children who were not infected with HIV and who received placebo, the death rate was 5.5% versus 3.9% among HIV-uninfected children who received zinc (RR=0.7; 95% CI, 0.2-2.2).
“Acute respiratory tract infections are the most common cause of morbidity and deaths in children less than 5 years,” the authors wrote in their background. “Given these results,” the authors stated, “zinc could be considered for use as adjunct therapy for severe pneumonia, especially among Highly Active Antiretroviral Therapy-naïve, HIV-infected children in our environment.”
