Abstract

Background

Rabies is fatal encephalitis which is a major public health problem in Asian and African countries. Till date, only 12 cases have been reported who have survived after rabies. Case Report: In this communication we report a patient who is unique as the first documented long term rabies survivor with PCR positivity even after 4½ years of illness. Child sustained dog bite following which he received adequate prophylaxis. Within two weeks, child developed encephalopathy requiring evaluation. Child continues to have persistent myoclonic jerks, seizures, is dependent on all activities with severe neurological deficits. Nested reverse transcriptase PCR (RT-PCR) specific for rabies nucleoprotein gene in CSF and nuchal skin biopsy were positive for rabies viral RNA. The nuchal skin biopsy was also positive for rabies nucleoprotein antigen by fluorescent antibody test (FAT). We describe the clinical evolution and sequential MRI brain changes in this child.

Conclusions

Despite the uniformly dismal prognosis of human rabies, these unusual reports of survival of rabies patients may provide an impetus to explore newer therapeutic strategies for this otherwise fatal disease.

Why this case is important?

Rabies is a disease that results in fatal encephalitis caused by RNA virus that continues to be a major public health problem in Asian and African countries with global annual mortality of 61,000 human deaths [1] and 20,000 deaths in India [2]. Though rabies is still considered 100% fatal, occasional survivors have been reported [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14] (Table 1).We report the survival of a patient, with neurological sequelae, 4½ years after

Case description

An eight-year old boy presented to our hospital with neurological disturbances of 4½ years duration Fig. 1. He sustained a dog bite at the age of four years (2010) on the face following which he received rabies immunoglobulin and rabies vaccine (purified chick embryo cell vaccine – Rabipur – Day 0,3,7,14). Details of the dog were unavailable. On day 25 after the dog bite (Fig. 1(a,b)), he developed generalised body aches, fever, seizures and altered sensorium. MRI showed T2 and Flair

Other similar and contrasting cases in the literature

Other similar cases of PCR positive Rabies survival (except in the initial 1-2 months) cases has not been reported as illustrated in Table 1.

Discussion

Though rabies is preventable following post-exposure prophylaxis, it is almost always fatal once clinical manifestations develop. In the literature, 11 cases (including this one) have been published of patients who survived clinical rabies. Probably, based on unpublished reports, more survival cases exist (Table 1; Fig. 1(a,b)). Four (30.8%) of them had complete recovery while the rest, including our patient, had moderate to severe neurological sequelae in the form of quadriparesis and

      The viruses can be transmitted through the bite of infected bats or other infected mammals, resulting in fever, agitation, excessive salivation, and hydrophobia. Rabies has a dismal prognosis and limited treatment options once symptoms set in, with only 12 reported survivors globally.51 Diagnosis can be made by skin biopsy with PCR testing.52

      Citation Excerpt :

      In the absence of preventive or post-exposure vaccination the disease is almost invariably fatal: after the onset of clinical signs there is no treatment protocol that could save the life of infected patients, leading to the death of more than 60 000 people every year, which number is probably underestimated [1]. To date, less than 20 survivors of rabies were reported, predominantly with severe neurological sequelae [2–7]. Efforts to establish reliable therapeutic strategies have been unsuccessful yet.

      Taken together, the results in experimental animals and in humans indicate that a disintegration of sleep and wake progresses to brain death in rabies encephalitis. Recently, an EEG study in a report of an exceptional survivor to rabies showed slow background activity 5–6 Hz and frequent spikes and sharp waves (Netravathi et al., 2015). In February 2016, WHO focused attention on Zika virus (ZIKV), declaring it a Public Health Emergency of International Concern (Gulland, 2016).
