A case series of melioidosis: An underdiagnosed entity in Kerala
Abstract
Melioidosis is an emerging infection in India and is caused by a Gram-negative oxidase-positive bacilli, Burkholderia
pseudomallei which is present in soil and surface water in the endemic region. Clinical manifestations are protean varying from asymptomatic infection, multiple skin abscesses, chronic pneumonia mimicking tuberculosis, and fulminant septic shock with abscesses in multiple internal organs. Isolation of bacilli from aspirated fluids remains the gold standard of diagnosis. Lack of microbiological services in many parts of the state, protean nature of clinical manifestations, lack of awareness among clinicians, and misidentification of the organism as Pseudomonas
spp leads to delay in diagnosis and treatment. We have, retrospectively, analyzed 14 cases with culture-proven melioidosis diagnosed during 10 years. Case records of culture-positive patients were retrospectively analyzed for demographic data, clinical characteristics, management, complications, and clinical outcomes. Out of these, 13 cases were male. The most common age group affected was 50–59 years. The major occupation affected was manual laborer. Nonbacteremic melioidosis accounted for 12 cases. Concerning clinical presentations, intra-abdominal abscesses mainly in the liver and spleen accounted for seven cases. All the isolates were susceptible to ceftazidime, meropenem, and doxycycline, whereas 12 isolates were susceptible to chloramphenicol, 11 isolates were susceptible to…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
