Gout is a disorder of uric acid metabolism, characterised by deposition of monosodium urate crystals in joints and periarticular soft tissues as well as renal calculi and chronic nephropathy. The accumulation of crystals in the joints and periarticular soft tissue may cause recurrent episodes inflammatory arthritis. Over the years chronic form may occur with presence of tophi and chronic arthropathy frequently in peripheral and rarely in axial joints. Surgical intervention is usually reserved for cases of recurrent attacks with deformities, severe pain and joint destructions.

| Introduction|| |
Gout is a metabolic disease that can manifest as acute or chronic arthritis and deposition of monosodium urate crystals in joints, bones and different body tissues, including the skin and soft tissues. Thus patients presenting with raised uric acid levels should be evaluated thoroughly to avoid further chronic conditions of gouty arthritis. The patients should also be monitored for renal function tests as there is a chance that high uric acid levels can lead to acute kidney injury. The high serum uric acid levels might be reasonable to determine which patients were at higher risk for worsening renal function in the near future and complicating the condition of gout further more. Thus the rare and unique feature about this case is that it showed the correlation of how high serum uric acid levels led to the derangement of renal function tests leading to acute kidney injury and vice versa.
| Case Report|| |
A 58-year-old male, resident of Nigdi, Pune, presented with multiple joint pain and difficulty in walking. The patient developed a swelling over the right foot 15 years back along with the elbow joint, wrist joint, and knee joint gradually [Figure 1] and [Figure 2]. He also complained of discharge of pus from few of the swellings. The swellings were painful and did not cause any restriction of the movement at the joint. There were stiffness and tenderness associated with the pain.

The laboratory parameters of the patient showed raised serum uric acid levels. The patient was thus treated with tablet febuxostat 40 mg bd and anti-fungal in view of the pus collection. Eventually, within a span of a week, there was a gradual rise in renal function tests (RFTs) of the patient. All other causes of acute kidney injury (AKI) were ruled out. This condition resolved gradually. He was then transferred to plastic surgery department where he underwent the surgery of removal of the lesions. Debridement was performed of the minor swellings. The AKI which had evolved as a consequence of the underlying condition was eventually resolved once the uric acid levels were back to normal. The pus collection from the swelling was taken on a swab and sent to microbiology department for examination [Figure 3]. Deposition of monosodium urate crystals in the bones was seen out of which smears were formed of the crystals on the slide and were sent to the pathology department for further investigation. The monosodium urate crystals were observed under polarizing microscopy [Figure 4].

After clinicopathological workup, the diagnosis of gouty arthritis was made. On starting the treatment, the patient iimproved clinically, and uric acid levels were maintained within normal limits. The patient discharged on tablet febuxostat 40 mg twice a day.
| Discussion|| |
This case conveys us to be vigilant about the effects of high serum uric acid levels on kidney and vice versa how deranged RFTs will raise the serum uric acid levels.
The highest incidence occurs in the 65+ years age group, with males more than twice as likely to be afflicted as females.
High uric acid level can be attributed to uric acid elevating drugs, genetic predisposition, and dietary factors.
Gout is a metabolic disorder in which needle-shaped crystal of monosodium urate from supersaturated fluids is deposited in tissues resulting in gouty arthritis, tophi formation, uric acid nephrolithiasis, and renal impairment.,
Gout is an inflammatory arthritis caused by cellular reaction to monosodium urate crystal deposition. Tophi are chalky, gritty accumulations of monosodium urate crystals that build up in soft tissue of an untreated gouty joint.
