Borrelia burgdorferi infection was diagnosed serologically in a dog with lethargy, stiffness, and anorexia. Treatment with ampicillin and chloramphenicol did not alleviate the signs. Azotemia, proteinuria, cylindruria, pyuria, and hematuria developed over a 3-month period. Antibody titer for B burgdorferi remained high (1:8,192) during this time. Renal histopathologic findings included severe, chronic, diffuse, membranoproliferative glomerulonephritis and moderate chronic, multifocal, interstitial nephritis. Borrelia burgdorferi organisms were identified in renal tissue and in urine by results of immunofluorescent studies and bacteriologic culture, respectively.

A guild of organisms carried by the same vector (Ixodes ticks) in Lyme-endemic areas may be confounding the understanding of Lyme disease in dogs. A new diagnostic method, the C6 peptide test for Lyme, and serology and PCR testing for Ehrlichia, Babesia, and Bartonella species will help to sort out seroprevalence and symptomatology caused by exposure to these agents or by coinfections. In addition, Rickettsia, Leptospira, Mycoplasma species, and more could be involved in dogs diagnosed with a "doxycycline-responsive" disease. The author does not recommend treating asymptomatic Borrelia carrier dogs, but does recommend screening them for proteinuria and for exposure to other agents. A positive Lyme titer is a marker of exposure to Ixodes ticks and the agents they carry. The risk/benefit of vaccination will be understood better as the symptomatology and immunopathogenesis of Lyme disease are defined. Meanwhile, tick control is highly recommended for all dogs in Lyme-endemic areas.

The purpose of this report is to offer a consensus opinion of ACVIM diplomates on the diagnosis, treatment, and prevention of Borrelia burgdorferi infections in dogs (canine Lyme disease). Clinical syndromes known to commonly be associated with canine Lyme disease include polyarthritis and glomerulopathy. Serological test results can be used to document exposure to B. burgdorferi but not prove illness. Although serum enzyme-linked immunosorbent assay/indirect fluorescent antibody assay titers can stay positive for months to years after treatment, quantitative C6 peptide antibody paired tests need more study. Serological screening of healthy dogs is controversial because it can lead to overdiagnosis or overtreatment of normal dogs, most of which never develop Lyme disease. However, serological screening can provide seroprevalence and sentinel data and stimulate owner education about tick infections and control. Although it is unknown whether treatment of seropositive healthy dogs is beneficial, the consensus is that seropositive dogs should be evaluated for proteinuria and other coinfections and tick control prescribed. Tick control can include a product that repels or protects against tick attachment, thereby helping to prevent transmission of coinfections as well as Borrelia spp. Seropositive dogs with clinical abnormalities thought to arise from Lyme disease generally are treated with doxycycline (10 mg/kg q24h for 1 month). Proteinuric dogs might need longer treatment as well as medications and diets for protein-losing nephropathy. The ACVIM diplomates believe the use of Lyme vaccines still is controversial and most do not administer them. It is the consensus opinion that additional research is needed to study predictors of illness, "Lyme nephropathy," and coinfections in Lyme endemic areas.

We report two cases of Lyme disease-associated glomerulonephritis. A 57-year-old female presented with rash, volume overload, hypertension and rapidly progressive glomerulonephritis. Biopsy confirmed an immune complex-mediated, membranoproliferative lesion. She was treated successfully with steroids and antibiotics. In a second case, a 40-year-old male, with a previously known microscopic hematuria, presented with rash, arthralgias, new proteinuria and gross hematuria following a tick bite. Biopsy revealed focal proliferative IgA nephropathy. Treatment with steroids and antibiotics resulted in rapid resolution of findings. Acute Lyme disease may contribute to the development of de novo, or activation of previously quiescent, immune-mediated glomerular disease.

Scleritis is a very uncommon manifestation in patients with IgA nephropathy. Here, we report the case of a patient presenting with diffuse anterior scleritis in which the laboratory disclosed microscopic haematuria and nephrotic range proteinuria. Renal function was normal. Serology for lupus, vasculitis and cryoglobulinaemia was negative. Rheumatoid factor was negative, and serum C3 and serum C4 were on the normal range. Serology for human immunodeficiency virus types 1 and 2, hepatitis B, hepatitis C, syphilis, and Lyme disease was also negative. A renal biopsy was performed and revealed IgA nephropathy. Oral steroids were then started, and 6 months later, the patient was asymptomatic. Scleritis did not recur, and ophthalmologic examination was normal; however, proteinuria was still in non-nephrotic range. Renal function still remains normal.
